本申请涉及一种手握式泵，该手握式泵特别是在容纳诸如洗手液、沐浴露、洗衣液等的卫生洗护制品的容器上使用。The present application relates to a hand-held pump, which is particularly used on a container containing sanitary cleaning products such as hand soap, shower gel, laundry detergent and the like.
在用于洗手液、沐浴露、洗衣液等的卫生洗护产品的容器中，通常会在该容器上设置用来分配产品的装置，例如按压泵等。In containers for sanitary cleaning products such as hand soap, shower gel, laundry detergent, etc., a device for dispensing the product, such as a press pump, etc., is usually provided on the container.
图10中示出了一种现有技术的按压泵1。该按压泵1包括压头10和气缸20，在压头10上连接有活塞30，活塞30延伸到气缸20的内部。在活塞30和气缸20之间设置有弹簧40。例如，如图10所示，弹簧40的一端支承在气缸20的底部上，另一端支承在活塞30的下端。通过弹簧40的作用，将活塞30连同压头10一起向上偏置。进一步地，在气缸20的底部设置有单向阀50。FIG10 shows a prior art compression pump 1. The compression pump 1 includes a pressure head 10 and a cylinder 20, and a piston 30 is connected to the pressure head 10, and the piston 30 extends to the inside of the cylinder 20. A spring 40 is provided between the piston 30 and the cylinder 20. For example, as shown in FIG10, one end of the spring 40 is supported on the bottom of the cylinder 20, and the other end is supported on the lower end of the piston 30. Through the action of the spring 40, the piston 30 is biased upward together with the pressure head 10. Further, a one-way valve 50 is provided at the bottom of the cylinder 20.
图10所示的按压泵1的操作方式如下：当使用人向下按压压头10时，活塞30在气缸20内部向下运动，使气缸20内的压力上升，使得容纳在气缸20内的产品受压而经压头10的压嘴11泵送出来，并且，在气缸20内部压力的作用下，单向阀50关闭，阻止气缸20内的产品回流到容器(未示出)内。而当使用人松开压头10时，在弹簧40的作用下，活塞30和压头10向上运动，此时气缸20内的压力下降，直至低于容器内的压力，从而在气缸20内形成负压，在该负压作用下，单向阀50打开，允许容器内的产品流入气缸20内部。The operation mode of the pressing pump 1 shown in FIG10 is as follows: when the user presses the pressure head 10 downward, the piston 30 moves downward inside the cylinder 20, causing the pressure inside the cylinder 20 to rise, so that the product contained in the cylinder 20 is pressurized and pumped out through the pressure nozzle 11 of the pressure head 10, and under the action of the pressure inside the cylinder 20, the one-way valve 50 is closed to prevent the product in the cylinder 20 from flowing back into the container (not shown). When the user releases the pressure head 10, under the action of the spring 40, the piston 30 and the pressure head 10 move upward, and the pressure inside the cylinder 20 decreases until it is lower than the pressure inside the container, thereby forming a negative pressure inside the cylinder 20, and under the action of the negative pressure, the one-way valve 50 opens to allow the product in the container to flow into the cylinder 20.
通常来说，使用人在操作图10所示的按压泵1时都是用单指来按压，特别是用食指来进行按压。食指的按压力量相对来说较小，而按压泵的出液量又比较大，因此在使用过程中会非常费劲，也十分地不方便。Generally speaking, when operating the pressing pump 1 shown in Fig. 10, the user uses a single finger to press, especially the index finger. The pressing force of the index finger is relatively small, and the liquid output of the pressing pump is relatively large, so it is very strenuous and inconvenient during use.
因此，存在对改进的用于分配产品的泵的需求，该泵允许使用人方便且省力地来分配容器中的产品。Therefore, there is a need for an improved pump for dispensing a product that allows a user to conveniently and labor-savingly dispense the product from a container.
发明内容Summary of the invention
本申请是为了解决以上所述的现有技术中所存在的技术问题而作出的。本申请的目的是提供一种泵，该泵能够允许使用人单手操作，并且便于使用人施力。This application is made to solve the technical problems existing in the above-mentioned prior art.

按压部，该按压部与气缸或活塞相连接或一体形成。A pressing portion is connected to or integrally formed with the cylinder or the piston.
在本申请的具有上述结构的手握式泵中，将气缸设置成其轴线沿着非竖直的方向延伸，进而在气缸或活塞上设置按压部，由此可允许使用人以手握的姿势来操作。因此，本申请的手握式泵允许使用人用单手来进行操作，且便于使用人施力。In the hand-held pump of the present application with the above structure, the cylinder is arranged so that its axis extends in a non-vertical direction, and a pressing portion is arranged on the cylinder or the piston, thereby allowing the user to operate it in a hand-held posture. Therefore, the hand-held pump of the present application allows the user to operate it with one hand, and it is convenient for the user to apply force.
进一步地，按压部可包括按压面，供使用人的手指按压，按压面被设置成，使使用人的手指施加在按压部上的按压力的方向与气缸的轴线相一致。Furthermore, the pressing portion may include a pressing surface for pressing by a user's finger, and the pressing surface is configured so that the direction of the pressing force applied by the user's finger on the pressing portion is consistent with the axis of the cylinder.
这样，使用人施加在按压部上的力可以基本上完全作用在气缸上，由此提高力的使用效率。In this way, the force applied by the user to the pressing part can basically act completely on the cylinder, thereby improving the efficiency of force use.
在本申请的一种实施方式中，手握式泵还包括量杯，量杯连接于出口，使得从出口泵出的产品能够流入量杯中。量杯上设置有刻度，从而便于计量由手握式泵从容器中泵送出的产品的量。In one embodiment of the present application, the hand-held pump further comprises a measuring cup, which is connected to the outlet so that the product pumped out of the outlet can flow into the measuring cup. The measuring cup is provided with a scale to facilitate measuring the amount of the product pumped out of the container by the hand-held pump.
较佳地，量杯包括量杯盖和/或导流口。量杯盖可保护量杯中的产品免受外部的影响，而导流口可在将产品从量杯中倾倒出来的时候起到导流的作用。Preferably, the measuring cup includes a measuring cup cover and/or a flow guide. The measuring cup cover can protect the product in the measuring cup from external influences, and the flow guide can play a role of guiding when pouring the product out of the measuring cup.
在另一种实施方式中，手握式泵还可包括出液管，出液管与出口相连接。由手握式泵从容器中泵送出的产品可经出液管直接流出。In another embodiment, the handheld pump may further include a liquid outlet tube connected to the outlet, and the product pumped from the container by the handheld pump may flow directly out through the liquid outlet tube.
较佳地，在出口中设置有通孔，而出液管能够相对于出口在第一位置和第二位置之间旋转，当出液管处于第一位置时，出口的通孔与出液管的侧壁相对，从而关闭出口与出液管的通道之间的连通，而当出液管处于第二位置时，出口的通孔与出液管的通道相连通，从而打开出口与出液管的通道之间的连通。通过该设置，可使手握式泵具有密封的出厂状态和打开的使用状态，并可在这两个状态之间切换。Preferably, a through hole is provided in the outlet, and the liquid outlet pipe can rotate relative to the outlet between a first position and a second position. When the liquid outlet pipe is in the first position, the through hole of the outlet is opposite to the side wall of the liquid outlet pipe, thereby closing the communication between the outlet and the channel of the liquid outlet pipe, and when the liquid outlet pipe is in the second position, The through hole of the outlet is connected to the channel of the liquid outlet pipe, thereby opening the communication between the outlet and the channel of the liquid outlet pipe. Through this arrangement, the hand-held pump can have a sealed factory state and an open use state, and can be switched between these two states.
较佳地，在出口中还可设置有第二单向阀，第二单向阀允许产品从手握式泵流到外部。由此，可进一步有利于控制对产品的分配。Preferably, a second one-way valve may also be provided in the outlet, the second one-way valve allowing the product to flow from the hand-held pump to the outside. Thus, it is further beneficial to control the distribution of the product.
较佳地，按压面上形成有手指仿形的凹陷部。这可便于使用人的手指按压在按压面上，并且防止手指在按压过程中打滑。进一步地，按压面可设置成供两个手指或更多手指按压。Preferably, a finger-shaped recess is formed on the pressing surface. This can facilitate the user's fingers to press on the pressing surface and prevent the fingers from slipping during the pressing process. Further, the pressing surface can be configured to be pressed by two or more fingers.
在一种具体结构中，入口和出口设置在气缸上，手握式泵还包括气缸盖，气缸盖安装在气缸上，以及In a specific structure, the inlet and the outlet are arranged on the cylinder, and the hand-held pump further comprises a cylinder cover, which is mounted on the cylinder, and
按压部具有筒形的外壁，筒形的外壁可滑动地套设在气缸和/或气缸盖的外周上，其中，活塞设置在按压部中，弹簧围绕着活塞的活塞杆设置，且弹簧的一端抵接在气缸盖上，弹簧的另一端抵接在按压部上。The pressing portion has a cylindrical outer wall, which can be slidably mounted on the outer periphery of the cylinder and/or the cylinder head, wherein the piston is arranged in the pressing portion, the spring is arranged around the piston rod of the piston, and one end of the spring abuts on the cylinder head, and the other end of the spring abuts on the pressing portion.
即，在该结构中，按压力使得活塞相对于气缸滑动，而气缸则相对固定。并且，在该结构中，弹簧是外置式的，不与产品相接触，从而可避免产品对弹簧的不利影响，如腐蚀等。That is, in this structure, the pressing force causes the piston to slide relative to the cylinder, while the cylinder is relatively fixed. In addition, in this structure, the spring is external and does not contact the product, thereby avoiding the adverse effects of the product on the spring, such as corrosion.
较佳地，在按压部的内部设置有活塞安装部，活塞连接在活塞安装部上；或者，活塞一体形成在按压部中。Preferably, a piston mounting portion is provided inside the pressing portion, and the piston is connected to the piston mounting portion; or, the piston is integrally formed in the pressing portion.
较佳地，在气缸内设置有与容器的内部相连通的平衡孔，当按压部处于被弹簧偏置的位置时，活塞的活塞头封闭平衡孔。通过设置该平衡孔，可以在泵送产品的过程中对容器中形成的负压进行补偿。Preferably, a balancing hole connected to the interior of the container is provided in the cylinder, and when the pressing portion is in a position biased by the spring, the piston head of the piston closes the balancing hole. By providing the balancing hole, the negative pressure formed in the container can be compensated during the process of pumping the product.
较佳地，手握式泵中还设置有锁定机构，锁定机构能够锁定活塞和/或按压部相对于气缸沿气缸的轴线的运动。Preferably, a locking mechanism is further provided in the handheld pump, and the locking mechanism can lock the movement of the piston and/or the pressing part relative to the cylinder along the axis of the cylinder.
该锁定机构的一种具体结构为，在活塞杆上形成有凸块，在气缸盖上形成有凹槽，有该凸块和凹槽构成锁定机构，其中当凸块与凹槽相对准时，允许活塞相对于气缸沿气缸的轴线运动，而当凸块与凹槽错开时，凸块与气缸盖相抵接，从而锁定活塞相对于气缸沿气缸的轴线的运动。由此，凸块和凹槽的结构形成锁定机构。A specific structure of the locking mechanism is that a bump is formed on the piston rod and a groove is formed on the cylinder head, and the bump and the groove constitute the locking mechanism, wherein when the bump and the groove are aligned, the piston is allowed to move relative to the cylinder along the axis of the cylinder, and when the bump and the groove are misaligned, the bump abuts against the cylinder head, thereby locking the movement of the piston relative to the cylinder along the axis of the cylinder. Thus, the structure of the bump and the groove forms the locking mechanism.
或者，在按压部和气缸盖中的一个上形成有内螺纹，在按压部和气缸盖的另一个上形成有外螺纹，内螺纹与外螺纹相配合，构成锁定机构。Alternatively, an internal thread is formed on one of the pressing portion and the cylinder head, and an internal thread is formed on the pressing portion and the cylinder head. An external thread is formed on the other of the two members, and the internal thread cooperates with the external thread to form a locking mechanism.
在另一种结构中，手握式泵还包括通道部，活塞固定连接或一体形成在通道部上，In another configuration, the handheld pump further includes a channel portion, the piston being fixedly connected to or integrally formed on the channel portion.
其中，通道部包括：入口部分，入口部分包括入口，并将容纳有产品的容器的内部与活塞的内部空间连通；出口部分，出口部分包括出口，并将活塞的内部空间与外部环境相连通；The channel portion includes: an inlet portion, which includes an inlet and connects the interior of the container containing the product with the internal space of the piston; and an outlet portion, which includes an outlet and connects the internal space of the piston with the external environment.
并且，气缸的一端开口，并可滑动地套设在活塞的活塞头上，而在气缸的另一端上设置有按压部，并且，在气缸的一端上设置有气缸盖，弹簧围绕着活塞的活塞杆设置，且弹簧的一端抵接在气缸盖上，弹簧的另一端抵接在活塞或通道部上。Furthermore, one end of the cylinder is open and slidably mounted on the piston head of the piston, and a pressing portion is provided on the other end of the cylinder. In addition, a cylinder cover is provided on one end of the cylinder, and a spring is provided around the piston rod of the piston, with one end of the spring abutting on the cylinder cover, and the other end of the spring abutting on the piston or the channel portion.
可见，在该结构中，按压力使得气缸滑动，而活塞保持不动。并且，在该结构中，弹簧也是外置式的。It can be seen that in this structure, the pressing force causes the cylinder to slide, while the piston remains stationary. Also, in this structure, the spring is also external.
进一步地，在通道部中形成有与容器的内部相连通的平衡孔，并且在气缸盖上形成有密封片，当气缸处于被弹簧所偏置的位置时，密封片封闭平衡孔。由此，形成对容器内的负压进行补偿的机构。Furthermore, a balancing hole connected to the interior of the container is formed in the channel portion, and a sealing sheet is formed on the cylinder head, and when the cylinder is in a position biased by the spring, the sealing sheet closes the balancing hole, thereby forming a mechanism for compensating for negative pressure in the container.
本申请中的弹性复位机构可以采取各种形式，例如弹性复位机构可以是弹簧，该弹簧的一端支承在诸如气缸之类的固定部件上，另一端支承在诸如活塞杆或按压部之类的活动部件上。或者，弹性复位机构可以是弹性条，其可由塑料制成。The elastic reset mechanism in the present application can take various forms, for example, the elastic reset mechanism can be a spring, one end of which is supported on a fixed component such as a cylinder, and the other end is supported on a movable component such as a piston rod or a pressing part. Alternatively, the elastic reset mechanism can be an elastic strip, which can be made of plastic.

图1a和1b示出了本申请的第一实施例的手握式泵100的示意性截面图，其中图1a示出的是该手握式泵100处于未被按压或锁定的状态，而图1b示出的是该手握式泵100处于被按压的状态。图2a～5b示出了该手握式泵100的各部件的具体结构。Figures 1a and 1b are schematic cross-sectional views of a hand-held pump 100 according to a first embodiment of the present application, wherein Figure 1a shows the hand-held pump 100 in an unpressed or unlocked state, and Figure 1b shows the hand-held pump 100 in a pressed state. Figures 2a to 5b show the specific structures of the components of the hand-held pump 100.
如图1a和1b所示，手握式泵100具有气缸110，在气缸110上连接有气缸盖120。按压部130套设在气缸110和/或气缸盖120上，并且在按压部130和气缸盖120之间设置有弹簧150，该弹簧150的一端抵接在气缸盖120上，另一端抵接在按压部130上，将按压部130朝着远离气缸110的方向偏压。As shown in FIGS. 1a and 1b , the hand-held pump 100 comprises a cylinder 110 to which a gas The pressing portion 130 is sleeved on the cylinder 110 and/or the cylinder head 120, and a spring 150 is provided between the pressing portion 130 and the cylinder head 120, one end of the spring 150 abuts on the cylinder head 120, and the other end abuts on the pressing portion 130, biasing the pressing portion 130 in a direction away from the cylinder 110.
活塞140连接在按压部130上，并穿过气缸盖120中的开口延伸到气缸110的内部空间中。The piston 140 is connected to the pressing portion 130 and extends into the inner space of the cylinder 110 through an opening in the cylinder head 120 .
在气缸110的下部连接有牙套160，该牙套160与容纳有产品的容器(未示出)的出口相连接，由此将气缸110安装到容器上。A toothed sleeve 160 is connected to the lower portion of the cylinder 110, and the toothed sleeve 160 is connected to an outlet of a container (not shown) containing a product, thereby mounting the cylinder 110 on the container.
进一步地，如图1a和1b所示，手握式泵100还包括量杯170，该量杯170与气缸盖120的出口相连通。由此，由手握式泵100泵送出的液态或半液态的产品首先流入量杯170中，从而允许使用人控制所要使用的产品的量。1a and 1b, the hand-held pump 100 further includes a measuring cup 170, which is connected to the outlet of the cylinder head 120. Thus, the liquid or semi-liquid product pumped by the hand-held pump 100 first flows into the measuring cup 170, thereby allowing the user to control the amount of the product to be used.
下面将参照图2a～5b同时结合图1a和1b来具体描述手握式泵100的各组成部件的结构和它们的连接关系。The structures of the components of the handheld pump 100 and their connection relationships will be described in detail below with reference to FIGS. 2a to 5b and in combination with FIGS. 1a and 1b.
气缸cylinder
图2a和2b分别示出了气缸110的纵向剖视图和立体图。如图2a所示，气缸110包括气缸本体113，该气缸本体113具有沿大致水平方向延伸的气缸轴线A。气缸本体113上设有气缸入口111和气缸出口112，其中气缸入口111通入容器内部，气缸出口112通向外部环境。从图1a中可见，在气缸入口111中设有入口单向阀118，在气缸出口112中设有出口单向阀119。在一种未示出的示例中，也可只在气缸入口111处设置单向阀，也可基本实现手握式泵100的泵送产品的功能。2a and 2b respectively show a longitudinal cross-sectional view and a stereoscopic view of the cylinder 110. As shown in FIG2a, the cylinder 110 includes a cylinder body 113 having a cylinder axis A extending in a substantially horizontal direction. The cylinder body 113 is provided with a cylinder inlet 111 and a cylinder outlet 112, wherein the cylinder inlet 111 leads to the interior of the container and the cylinder outlet 112 leads to the external environment. As can be seen from FIG1a, an inlet check valve 118 is provided in the cylinder inlet 111, and an outlet check valve 119 is provided in the cylinder outlet 112. In an example not shown, a check valve may be provided only at the cylinder inlet 111, and the function of pumping a product of the hand-held pump 100 may also be basically achieved.
气缸本体113的另一端开口，并且在其内周上设有卡配部117，用于安装气缸盖120。卡配部117的一种实例是周向凹槽，相应地，在气缸盖120上设置有周向凸条，在安装状态下，该周向凸条过盈配合在周向凹槽中，从而将气缸盖120固定在气缸110上。当然，卡配部117也可以是其它现有技术中已知的连接结构。例如，卡配部117可以是周向凹槽的形式，相对应的，在气缸盖120上设置的是形状互补的周向凸条，再例如，卡配部117可以是内螺纹，而在气缸盖120上相应地设置有相匹配的外螺纹。The other end of the cylinder body 113 is open, and a snap-fitting portion 117 is provided on the inner circumference thereof for installing the cylinder head 120. An example of the snap-fitting portion 117 is a circumferential groove, and accordingly, a circumferential convex strip is provided on the cylinder head 120. In the installed state, the circumferential convex strip is interference-fitted in the circumferential groove, thereby fixing the cylinder head 120 on the cylinder 110. Of course, the snap-fitting portion 117 may also be other connection structures known in the prior art. For example, the snap-fitting portion 117 may be in the form of a circumferential groove, and correspondingly, a circumferential convex strip with a complementary shape is provided on the cylinder head 120. For another example, the snap-fitting portion 117 may be an internal thread, and a matching external thread is correspondingly provided on the cylinder head 120.
图2a和2b所示的气缸110还包括安装部114，牙套160连接在安装部114上，如图1a中所示的。具体来说，在安装部114的下部形成有凸缘115，在安装好的状态下，牙套160的上部设置的卡爪161卡配在该凸缘115上。当然，此处所述的连接方式也是示例性的，也可用其它方式将牙套160配合在气缸110上，例如螺纹连接等。The cylinder 110 shown in Figures 2a and 2b also includes a mounting portion 114, and the toothed sleeve 160 is connected to the mounting portion 114, as shown in Figure 1a. Specifically, a flange 115 is formed at the lower portion of the mounting portion 114. In the installed state, the claw 161 provided on the upper part of the toothed sleeve 160 is clamped on the flange 115. Of course, the connection method described here is also exemplary, and the toothed sleeve 160 can also be matched on the cylinder 110 in other ways, such as threaded connection, etc.
作为一个较佳的结构，在气缸本体113上还设有平衡孔116，该平衡孔116被设置成，在使用过程中允许容纳产品的容器内部与外界空气连通，从而平衡容器内的负压，这将在下文中具体描述。As a preferred structure, a balancing hole 116 is also provided on the cylinder body 113. The balancing hole 116 is configured to allow the interior of the container containing the product to communicate with the outside air during use, thereby balancing the negative pressure in the container, which will be described in detail below.
活塞piston
图3a和3b分别示出了活塞140的纵向剖视图和立体图。活塞140包括活塞杆141和活塞头142，活塞杆141的一端连接在按压部130上，例如通过凹槽-凸条的配合结构，或者通过其它现有技术中已知的连接方式，如螺纹连接等。活塞头142的外径被设置成略大于气缸本体113的内径，从而与气缸本体113的内部紧密接触。3a and 3b respectively show a longitudinal cross-sectional view and a three-dimensional view of the piston 140. The piston 140 includes a piston rod 141 and a piston head 142. One end of the piston rod 141 is connected to the pressing portion 130, for example, by a groove-rib matching structure, or by other connection methods known in the prior art, such as threaded connection, etc. The outer diameter of the piston head 142 is set to be slightly larger than the inner diameter of the cylinder body 113, so as to be in close contact with the inside of the cylinder body 113.
在一种较佳的结构中，在活塞杆141上设置有凸块143，相应地，在气缸盖120上设置有凹槽121(见图1b)。当凸块143与凹槽121对准时，活塞140可以沿着气缸110的气缸轴线A在气缸110内部往复运动，如图1a所示的状态；通过旋转按压部130，使活塞140也随之旋转，从而使凸块143与凹槽121相互错开，此时凸块143与气缸盖120相抵接，由此锁定按压部130的运动，如图1b所示的状态。In a preferred structure, a protrusion 143 is provided on the piston rod 141, and correspondingly, a groove 121 is provided on the cylinder head 120 (see FIG. 1b). When the protrusion 143 is aligned with the groove 121, the piston 140 can reciprocate inside the cylinder 110 along the cylinder axis A of the cylinder 110, as shown in the state of FIG. 1a; by rotating the pressing part 130, the piston 140 also rotates, so that the protrusion 143 and the groove 121 are staggered, and at this time the protrusion 143 abuts against the cylinder head 120, thereby locking the movement of the pressing part 130, as shown in the state of FIG. 1b.
按压部Pressing part
图4a和4b分别示出了按压部130的剖视图和立体图。按压部130的外壁呈大致筒形的形状，在按压部130的内部形成有活塞安装部131，如以上所述的，活塞140能够如图1a和1b中所示的那样连接在活塞安装部131上。在另一种未示出的结构中，活塞140可以一体地形成在按压部130上。4a and 4b respectively show a cross-sectional view and a stereoscopic view of the pressing portion 130. The outer wall of the pressing portion 130 is substantially cylindrical, and a piston mounting portion 131 is formed inside the pressing portion 130. As described above, the piston 140 can be connected to the piston mounting portion 131 as shown in FIGS. 1a and 1b. In another structure not shown, the piston 140 can be integrally formed on the pressing portion 130.
当活塞140连接或一体形成在按压部130上时，在按压部130的筒形的外壁和活塞140的活塞杆141之间形成环形空间。弹簧150设置在该环形空间中，其一端抵接在按压部130上，另一端抵接在气缸盖120上，并包围着活塞140的活塞杆141，如图1a和1b所示。由此，在本申请中，弹簧140为外置式弹簧的形式，从而不与产品，由此可避免产品对弹簧的负面影响，比如腐蚀等。When the piston 140 is connected or integrally formed on the pressing portion 130, an annular space is formed between the cylindrical outer wall of the pressing portion 130 and the piston rod 141 of the piston 140. The spring 150 is arranged in the annular space, one end of which abuts on the pressing portion 130, and the other end abuts on the cylinder head 120, and surrounds the piston rod 141 of the piston 140, as shown in Figures 1a and 1b. Therefore, in the present application, the spring 140 is in the form of an external spring, so that it does not contact with the product, thereby avoiding the negative impact of the product on the spring, such as corrosion, etc.
按压部130一端开口，并可滑动地套设在气缸110和/或气缸盖120上，而在按压部130的另一端上则形成有按压面132。在使用过程中，使用人可用两个手指或多个手指按压在按压部130的按压面132上，并能够沿着气缸110的气缸轴线A施加按压力。One end of the pressing portion 130 is open and can be slidably mounted on the cylinder 110 and/or the cylinder head 120, and a pressing surface 132 is formed on the other end of the pressing portion 130. During use, the user can press the pressing surface 132 of the pressing portion 130 with two or more fingers, and can apply a pressing force along the cylinder axis A of the cylinder 110.
较佳地，按压面132上形成有手指仿形的凹陷，以便于手指按压在按压面132上，并有助于防止手指在按压过程中打滑。Preferably, a finger-shaped depression is formed on the pressing surface 132 to facilitate pressing of the finger on the pressing surface 132 and to help prevent the finger from slipping during the pressing process.
量杯Measuring cup
图5a和5b示出了量杯170的剖视图和立体图。量杯170的周壁上设有刻度，用于计量量杯170内的产品料液的量。量杯170的底部设置有量杯进口管171，该量杯进口管171与气缸110的气缸出口112相配合，使得经气缸出口112被泵出的产品料液进入量杯170中。如图5a中清楚地示出的，在量杯进口管171中较佳地可容纳有出口单向阀119。5a and 5b show a cross-sectional view and a stereoscopic view of the measuring cup 170. The measuring cup 170 has a scale on its peripheral wall for measuring the amount of the product liquid in the measuring cup 170. The measuring cup 170 has a measuring cup inlet pipe 171 disposed at the bottom thereof, and the measuring cup inlet pipe 171 cooperates with the cylinder outlet 112 of the cylinder 110 so that the product liquid pumped out through the cylinder outlet 112 enters the measuring cup 170. As clearly shown in FIG5a , an outlet check valve 119 may preferably be accommodated in the measuring cup inlet pipe 171.
较佳地，量杯170的上边沿上可设置有导流口173，在倾倒容纳在量杯170中的产品料液的时候，该导流口173起到导流的作用。此外，如图1a所示，量杯170还可包括量杯盖172，该量杯盖172盖住量杯170，以减少或避免外界环境对量杯170中产品的影响。Preferably, a guide port 173 may be provided on the upper edge of the measuring cup 170, and the guide port 173 plays a role of guiding when pouring the product liquid contained in the measuring cup 170. In addition, as shown in FIG. 1a, the measuring cup 170 may also include a measuring cup cover 172, and the measuring cup cover 172 covers the measuring cup 170 to reduce or avoid the influence of the external environment on the product in the measuring cup 170.
此处，量杯进口管171是可选的结构，也可仅在量杯170的底部设置开口，供气缸入口111穿过。Here, the measuring cup inlet pipe 171 is an optional structure, and an opening may be provided at the bottom of the measuring cup 170 for the cylinder inlet 111 to pass through.
量杯170可以是可拆卸地安装在气缸110的气缸出口112上，从而允许在不需要量杯170时将量杯170拆下，并用其它部件来替换，例如出液管等，这将在其它的实施例中详细描述。The measuring cup 170 can be detachably mounted on the cylinder outlet 112 of the cylinder 110, thereby allowing the measuring cup 170 to be removed when it is not needed and replaced with other components, such as a liquid outlet pipe, etc., which will be described in detail in other embodiments.
手握式泵的操作Hand Pump Operation
下面将具体描述以上所公开的手握式泵100的操作方式。The operation of the handheld pump 100 disclosed above will be described in detail below.
在不使用时，如图1a所示，按压部130和连接于按压部130上的活塞140在弹簧150的作用下朝着远离气缸110的方向被偏置。此时，在气缸110中包括平衡孔116的情况下，活塞140的活塞头142所封闭，从而容器中容纳的产品不会溢出到容器外。When not in use, as shown in FIG1a, the pressing portion 130 and the piston 140 connected to the pressing portion 130 are biased in a direction away from the cylinder 110 by the spring 150. At this time, in the case where the cylinder 110 includes a balancing hole 116, the piston head 142 of the piston 140 is closed, so that the product contained in the container does not overflow out of the container.
当需要从容器中分配产品时，使用人的两个或更多根手指按压在按压部130的按压面132上，使得按压部130朝着靠近气缸110的方向克服弹簧150的偏置力而运动，此运动过程称为“按压行程”。在按压行程过程中，连接在按压部130上的活塞140在气缸110的内部运动。较佳地，按压部130是沿着气缸110的气缸轴线A运动，且按压力的施加方向也与气缸轴线A的方向相一致。When it is necessary to dispense the product from the container, two or more fingers of the user press on the pressing surface 132 of the pressing portion 130 so that the pressing portion 130 overcomes the spring 150 in a direction close to the cylinder 110. The pressing part 130 moves due to the biasing force, and this movement process is called "pressing stroke". During the pressing stroke, the piston 140 connected to the pressing part 130 moves inside the cylinder 110. Preferably, the pressing part 130 moves along the cylinder axis A of the cylinder 110, and the direction of the pressing force is also consistent with the direction of the cylinder axis A.
随着活塞140沿着靠近气缸110的方向运动，气缸110的气缸本体113内的容积减小，使得容纳在气缸110内的产品料液的压力上升。该上升的压力使入口单向阀118关闭，阻止气缸110内的产品料液回流到容器内，并且该压力使出口单向阀119打开(如果设有出口单向阀119的话)，从而使气缸110中的产品料液经气缸出口112和量杯进口管171流入量杯中。As the piston 140 moves in a direction close to the cylinder 110, the volume of the cylinder body 113 of the cylinder 110 decreases, causing the pressure of the product liquid contained in the cylinder 110 to rise. The rising pressure closes the inlet check valve 118, preventing the product liquid in the cylinder 110 from flowing back into the container, and the pressure opens the outlet check valve 119 (if the outlet check valve 119 is provided), so that the product liquid in the cylinder 110 flows into the measuring cup through the cylinder outlet 112 and the measuring cup inlet pipe 171.
并且，随着活塞140的运动，原本封闭平衡孔116的活塞头142从平衡孔116移开，由此使容器内部能够与外界环境相连通。Furthermore, as the piston 140 moves, the piston head 142 that originally closes the balancing hole 116 moves away from the balancing hole 116, thereby allowing the interior of the container to communicate with the external environment.
在按压行程到达终点之后，使用人撤去对按压部130的按压力，按压部130和连接在按压部130上的活塞140在弹簧150的作用下朝着远离气缸110的方向运动，恢复其初始的状态，此运动过程为“恢复行程”。在此恢复行程中，气缸110中的内部空间变大，其中的压力下降，形成负压。在此负压作用下，出口单向阀119关闭，而入口单向阀118打开，允许容器中的产品补充到气缸110内。并且，平衡孔116仍保持未被活塞头142封闭的状态，从而容器内部与外部环境连通，从而补偿容器内部由于产品料液被泵出而产生的负压。After the pressing stroke reaches the end point, the user removes the pressing force on the pressing part 130, and the pressing part 130 and the piston 140 connected to the pressing part 130 move in a direction away from the cylinder 110 under the action of the spring 150, and restore their initial state. This movement process is the "recovery stroke". In this recovery stroke, the internal space in the cylinder 110 becomes larger, and the pressure therein decreases, forming a negative pressure. Under the action of this negative pressure, the outlet check valve 119 is closed, and the inlet check valve 118 is opened, allowing the product in the container to be replenished into the cylinder 110. In addition, the balance hole 116 remains unsealed by the piston head 142, so that the interior of the container is connected to the external environment, thereby compensating for the negative pressure generated inside the container due to the product liquid being pumped out.
而在恢复行程的终点，即，当按压部130和活塞140回到被弹簧150所偏置的位置时，活塞头142再次封闭平衡孔116，防止在不使用的时候容器内的产品溢出。At the end of the recovery stroke, that is, when the pressing portion 130 and the piston 140 return to the position biased by the spring 150, the piston head 142 closes the balancing hole 116 again to prevent the product in the container from overflowing when not in use.
当需要将按压部130设置在锁定位置时，先使按压部130和活塞140运动到按压行程的终点，然后转动按压部130，使活塞140的凸块143与气缸盖120的凹槽121错开。这样，凸块143就抵接在气缸盖120上，由此阻止按压部130和活塞140朝着远离气缸110的方向运动。When the pressing part 130 needs to be set in the locking position, the pressing part 130 and the piston 140 are first moved to the end of the pressing stroke, and then the pressing part 130 is rotated to make the protrusion 143 of the piston 140 staggered with the groove 121 of the cylinder head 120. In this way, the protrusion 143 abuts against the cylinder head 120, thereby preventing the pressing part 130 and the piston 140 from moving in a direction away from the cylinder 110.
图6示出了在以上所述的第一的基础上进行变型的手握式泵100’。在该变型结构中，弹簧150’为内置式的，其两端分别抵接在气缸110’的底部和活塞140的头部之间。进一步地，按压部130’上设置有内螺纹133’，相应地，在气缸盖120’上形成有外螺纹122’，内螺纹133’和外螺纹122’能够相啮合，以构成锁定机构，锁定按压部130’的运动。FIG6 shows a hand-held pump 100' modified on the basis of the first structure described above. In this modified structure, the spring 150' is built-in, and its two ends are respectively abutted between the bottom of the cylinder 110' and the head of the piston 140. Further, the pressing portion 130' is provided with an internal thread 133', and correspondingly, the cylinder cover 120' is formed with an external thread 122', and the internal thread 133' and the external thread 122' can mesh with each other. This constitutes a locking mechanism to lock the movement of the pressing portion 130 ′.
当然，也可以在按压部130’上设置外螺纹，而在气缸盖120’上设置内螺纹，同样可获得用来锁定按压部130’的运动的锁定机构。Of course, it is also possible to provide an external thread on the pressing portion 130' and an internal thread on the cylinder head 120', and to obtain a locking mechanism for locking the movement of the pressing portion 130'.
<第二实施例及其变型例><Second Embodiment and Its Modifications>
图7a示出了本申请的第二实施例的手握式泵200。该第二实施例中的结构与第一实施例的相同之处在此不再详细描述，下面将重点描述第二实施例与第一实施例不同的特征。Fig. 7a shows a handheld pump 200 according to a second embodiment of the present application. The similarities between the structure of the second embodiment and the first embodiment will not be described in detail here, and the following will focus on the features that are different from the first embodiment.
如图7a所示，手握式泵200包括通道部260，该通道部260包括进口部分261和出口部分262。如图7a所示，活塞240固定连接在通道部260上，通道部260的进口部分261具有通入容器内部的入口211，并将容纳有产品的容器的内部与活塞240的内部空间连通，而通道部260的出口部分262具有通向外部环境的出口212，并将活塞240的内部空间与外部环境相连通。气缸210的一端开口，并可滑动地套设在活塞240的活塞头上，而在气缸210的另一端上设置有按压部230，供使用人的手指按压。As shown in Fig. 7a, the hand-held pump 200 includes a channel portion 260, which includes an inlet portion 261 and an outlet portion 262. As shown in Fig. 7a, the piston 240 is fixedly connected to the channel portion 260, and the inlet portion 261 of the channel portion 260 has an inlet 211 leading to the interior of the container, and connects the interior of the container containing the product with the internal space of the piston 240, while the outlet portion 262 of the channel portion 260 has an outlet 212 leading to the external environment, and connects the internal space of the piston 240 with the external environment. One end of the cylinder 210 is open and slidably mounted on the piston head of the piston 240, and a pressing portion 230 is provided on the other end of the cylinder 210 for the user's finger to press.
在气缸210的开口的一端上设置有气缸盖220。弹簧250的一端抵接在该气缸盖220上，另一端抵接在活塞240或通道部260上。由此，通过该弹簧250的弹簧力，将气缸210朝着远离活塞240的方向偏置。A cylinder head 220 is provided at one end of the opening of the cylinder 210. One end of a spring 250 abuts against the cylinder head 220, and the other end abuts against the piston 240 or the channel portion 260. Thus, the spring force of the spring 250 biases the cylinder 210 in a direction away from the piston 240.
在通道部260的下部较佳地设置有与第一实施例中的安装部114相似的安装结构，用于与牙套相连接。较佳地，在该安装结构上形成有平衡孔216，用于平衡容器内的负压。与之相应地，在气缸盖220上设置有密封片221，在气缸210的恢复行程的终点处，即，当气缸210处于被弹簧250所偏置的位置时，该密封片221封闭平衡孔216，防止在不使用的时候容器内的产品溢出。A mounting structure similar to the mounting portion 114 in the first embodiment is preferably provided at the lower portion of the channel portion 260 for connection with the dental cap. Preferably, a balancing hole 216 is formed on the mounting structure for balancing the negative pressure in the container. Accordingly, a sealing sheet 221 is provided on the cylinder head 220. At the end of the recovery stroke of the cylinder 210, that is, when the cylinder 210 is in a position biased by the spring 250, the sealing sheet 221 closes the balancing hole 216 to prevent the product in the container from overflowing when not in use.
可见，在第二实施例中，与第一实施例的不同之处在于，活塞240是固定的，而气缸210是相对运动的，且按压部230设置在气缸210上。It can be seen that in the second embodiment, the difference from the first embodiment is that the piston 240 is fixed, while the cylinder 210 is relatively movable, and the pressing portion 230 is disposed on the cylinder 210 .
与第一实施例的另一不同之处在于，如图7a所示，气缸210的气缸轴线A’并非是大致水平的，而是与水平方向呈一定角度，但该角度为锐角，即，气缸210的气缸轴线A’不会呈竖直的状态。Another difference from the first embodiment is that, as shown in Figure 7a, the cylinder axis A' of the cylinder 210 is not approximately horizontal, but is at a certain angle to the horizontal direction, but the angle is an acute angle, that is, the cylinder axis A' of the cylinder 210 is not vertical.
第二实施例与第一实施例的又一不同之处在于，该手握式泵200不包括量杯，而是用出液管270来作为替代的结构。Another difference between the second embodiment and the first embodiment is that the hand-held pump 200 does not include Instead of a measuring cup, a liquid outlet tube 270 is used as an alternative structure.
在图7b所示的变型结构的手握式泵200’中，在出液管270’与气缸210’的出口212’之间的连接部分处设置有可切换密封结构。具体来说，如图7b所示，在气缸210’的出口212’处设置有通孔213’，并且出液管270’可相对于出口212’在第一位置和第二位置之间转动。In the handheld pump 200' of the modified structure shown in Fig. 7b, a switchable sealing structure is provided at the connection portion between the liquid outlet pipe 270' and the outlet 212' of the cylinder 210'. Specifically, as shown in Fig. 7b, a through hole 213' is provided at the outlet 212' of the cylinder 210', and the liquid outlet pipe 270' can rotate between a first position and a second position relative to the outlet 212'.
当出液管270’位于第一位置时，出口212’上的通孔213’与出液管270’的侧壁相对，从而阻止产品经出口212’流入出液管270’中。在此，该第一位置可被设置为该手握式泵200’的出厂状态或密封状态。When the liquid outlet pipe 270' is located at the first position, the through hole 213' on the outlet 212' is opposite to the side wall of the liquid outlet pipe 270', thereby preventing the product from flowing into the liquid outlet pipe 270' through the outlet 212'. Here, the first position can be set as the factory state or sealed state of the handheld pump 200'.
当使用人要使用该产品时，可将出液管270’从第一位置转动到第二位置(例如转动90°)，此时出口212’的通孔213’与出液管270’内的通道相连通，从而允许产品经出口212’流到出液管270’中。因此，可将出液管270’处于第二位置的状态设为使用状态。When the user wants to use the product, the liquid outlet pipe 270' can be rotated from the first position to the second position (for example, rotated 90 degrees), at which time the through hole 213' of the outlet 212' is connected to the channel in the liquid outlet pipe 270', thereby allowing the product to flow into the liquid outlet pipe 270' through the outlet 212'. Therefore, the state of the liquid outlet pipe 270' in the second position can be set as the use state.
可以了解，以上所述的第二实施例中区别于第一实施例的特征可以分别用来替代第一实施例中的对应特征。例如，可以将出液管270”设置在第一实施例中，替代其量杯的设置，而按压部230”则仍保持基本水平地设置，如图7c所示；或者第一实施例中的其它特征可以不变，而只是将气缸设置成相对于水平方向倾斜。It can be understood that the features of the second embodiment described above that are different from the first embodiment can be used to replace the corresponding features in the first embodiment. For example, the liquid outlet pipe 270" can be set in the first embodiment to replace the setting of the measuring cup, while the pressing part 230" is still kept in a substantially horizontal setting, as shown in FIG. 7c; or other features in the first embodiment can remain unchanged, but only the cylinder is set to be inclined relative to the horizontal direction.
<第三实施例><Third Embodiment>
图8示出了本申请的第三实施例的手握式泵300。该第三实施例中的结构与第二实施例大体类似，在此不再详细描述，下面将重点描述第三实施例与第二实施例不同的特征。Fig. 8 shows a handheld pump 300 according to a third embodiment of the present application. The structure of the third embodiment is generally similar to that of the second embodiment, and will not be described in detail here. The following will focus on the features that are different between the third embodiment and the second embodiment.
可以看到，第三实施例的手握式泵300的结构与第二实施例的手握式泵200的结构基本相同。所不同之处在于，与通道部360的出口部分362相连通的是量杯370。It can be seen that the structure of the hand-held pump 300 of the third embodiment is substantially the same as that of the hand-held pump 200 of the second embodiment, except that a measuring cup 370 is connected to the outlet portion 362 of the channel portion 360 .
<第四实施例><Fourth Embodiment>
图9a和9b示出了本申请的第四实施例的手握式泵400，其中9a示出了手握式泵400的放松状态，而9b则示出了手握式泵400的被按压状态。该第三实施例中与第一实施例～第三实施例相同或类似的结构在此不再详细描述，下面将重点描述第四实施例与之前的实施例不同的特征。9a and 9b show a hand-held pump 400 according to a fourth embodiment of the present application, wherein 9a shows the hand-held pump 400 in a relaxed state, and 9b shows the hand-held pump 400 in a pressed state. The structures of the three embodiments that are the same or similar to those of the first to third embodiments will not be described in detail here, and the following will focus on describing the features that are different from the previous embodiments of the fourth embodiment.
如图9a和9b所示，手握式泵400包括气缸410、按压部430和量杯470。与之前的实施例不同的是，在第四实施例的手握式泵400中设置有弹性条450，用于提到之前的实施例中的弹簧。该弹性条450一端固定在气缸410上，另一端固定在按压部430上。当对按压部430进行按压时，弹性条450受压而弯曲变形，积蓄弹性力，当松开按压部430时，弹性条450的弹性力使按压部430复位。As shown in Figs. 9a and 9b, the hand-held pump 400 includes a cylinder 410, a pressing portion 430 and a measuring cup 470. Different from the previous embodiment, the hand-held pump 400 of the fourth embodiment is provided with an elastic strip 450, which is used as the spring in the previous embodiment. One end of the elastic strip 450 is fixed to the cylinder 410, and the other end is fixed to the pressing portion 430. When the pressing portion 430 is pressed, the elastic strip 450 is compressed and bent and deformed, accumulating elastic force. When the pressing portion 430 is released, the elastic force of the elastic strip 450 causes the pressing portion 430 to return to its original position.
该弹性条430可以与手握式泵430的其它部分一样由塑料材料制成，并且，该弹性条430还可以设置在气缸430之外。The elastic strip 430 may be made of plastic material like other parts of the hand-held pump 430 , and the elastic strip 430 may also be disposed outside the cylinder 430 .
该第四实施例的手握式泵400也可结合有以上的实施例中所包括的特征，例如，可以将图9a和9b中所示的量杯470替换为第二实施例中的出液管。The handheld pump 400 of the fourth embodiment may also be combined with the features included in the above embodiments. For example, the measuring cup 470 shown in FIGS. 9 a and 9 b may be replaced with the liquid outlet tube in the second embodiment.
