本发明涉及一种风扇及其用于该种风扇的喷嘴。The invention relates to a fan and a nozzle used for the fan.
背景技术Background technique
传统的风扇通常包括绕转轴旋转的一组叶片和用于驱动该组叶片旋转以产生气流的马达。该组叶片通常位于笼子内，该笼子允许气流穿过，而阻止人体接触到该组旋转的叶片。A conventional fan generally includes a set of blades rotating around a shaft and a motor for driving the rotation of the set of blades to generate air flow. The set of blades is typically located within a cage that allows airflow to pass through while preventing human access to the set of rotating blades.
该种风扇可以是各种尺寸和形状。例如，吊扇可具有至少l000mm的直径，且通常以悬挂的方式被安装在天花板上以提供向下的气流。又例如，台扇通常具有300mm的直径，且通常自由地竖立且易于移动。其它类型的风扇可放置于地板上或安装在墙壁上。Such fans can be of various sizes and shapes. For example, ceiling fans may have a diameter of at least 1000 mm and are typically mounted in a suspended fashion from the ceiling to provide downward airflow. As another example, desk fans typically have a diameter of 300mm and are typically free standing and easy to move. Other types of fans can be placed on the floor or mounted on a wall.
该种风扇的缺点是旋转叶片所产生的气流通常是不均匀的或“涌动的”。这对于使用者来说是不舒服的。另一缺点是旋转叶片虽然位于笼子内，但是在某些情况下，人体还有触及到旋转叶片的危险。The disadvantage of this type of fan is that the airflow produced by the rotating blades is usually uneven or "surge". This is uncomfortable for the user. Another disadvantage is that although the rotating blades are located in the cage, in some cases, the human body still has the danger of touching the rotating blades.
2011年7月20日授权公告号为CN201902359U的中国专利（申请号：201020647163.6）公开了一种风扇。该种风扇包括底座和设置有喷嘴的机头，该底座的顶面与机头底面之间球面滑动配合，使机头可相对于底座从不倾斜位置倾斜到倾斜位置。The Chinese patent (application number: 201020647163.6) with the authorized announcement number CN201902359U on July 20, 2011 discloses a fan. This kind of fan includes a base and a machine head provided with nozzles. The top surface of the base and the bottom surface of the machine head are in sliding fit, so that the machine head can be tilted from a non-tilted position to an inclined position relative to the base.
这种风扇没有外露的旋转叶片并能产生平稳的气流，提高了气流的质量和使用的安全性。但是，这种风扇的机头处于倾斜位置时，其稳定性不佳；风扇的整体外观也受到较大的影响。The fan has no exposed rotating blades and can generate a smooth airflow, which improves the quality of the airflow and the safety of use. However, when the machine head of this fan is in an inclined position, its stability is not good; the overall appearance of the fan is also greatly affected.

Since the supporting member 29 is a spring element, the spring element can effectively absorb some vibrations and noises from the motor 24 and the impeller 23 , otherwise these vibrations and noises are easily transmitted to the casing 21 through the impeller cover 22 and amplified.
底座10用于接合风扇100所在的表面。基座2还包括用于使基部8相对于底座10来回摆动的摆动机构，该摆动机构包括同步马达36，摆动机构的操作由电路装置37响应用户按下按钮13来控制。摆动范围优选地在60°和120°之间，且摆动机构被设置为每分钟执行3至6个摆动周期。用于供应电力到风扇的电缆（没有画出）穿过形成在底座10上的孔延伸。The base 10 is used to engage the surface on which the fan 100 is placed. The base 2 also includes a swing mechanism for swinging the base 8 back and forth relative to the base 10 , the swing mechanism comprising a synchronous motor 36 , the operation of which is controlled by a circuit arrangement 37 in response to pressing of the button 13 by the user. The swing range is preferably between 60° and 120°, and the swing mechanism is set to perform 3 to 6 swing cycles per minute. Cables (not shown) for supplying power to the fan extend through holes formed in the base 10 .
在本实施例中，马达24是直流无刷马达，马达的转速可通过电路装置37响应用户操作按钮12来改变。In this embodiment, the motor 24 is a DC brushless motor, and the rotation speed of the motor can be changed through the circuit device 37 in response to the user operating the button 12 .
为了操作风扇100，用户按下按钮11，响应该操作，电路装置37激活马达24以旋转叶轮23。叶轮23的旋转使空气通过空气进口9进入基座2的外壳21内。叶轮23所形成的气流经过集气罩32汇聚后被输送到喷嘴1中。To operate the fan 100 , the user presses the button 11 , in response to which the circuit arrangement 37 activates the motor 24 to rotate the impeller 23 . The rotation of the impeller 23 causes air to enter the housing 21 of the base 2 through the air inlet 9 . The airflow formed by the impeller 23 is delivered to the nozzle 1 after being converged by the air collecting hood 32 .
在喷嘴1中，气流分两股在主体4的内部通道14中行进。在内部通道14中行进的气流被排气口7所发射，喷嘴周围的部分空气被从排气口7所发射的气流所卷吸，这样从排气口7发射的气流与被卷吸的气流的结合构成从喷嘴1向前发射的总气流。In the nozzle 1 the gas flow travels in two streams in the internal channel 14 of the body 4 . The airflow traveling in the internal channel 14 is emitted by the exhaust port 7, and part of the air around the nozzle is entrained by the airflow emitted from the exhaust port 7, so that the airflow emitted from the exhaust port 7 and the entrained airflow The combination of constitutes the total air flow emitted forward from the nozzle 1.
图10展示了图1所示的风扇向前倾斜至某一位置的侧视图，图11展示了图1所示的风扇向后倾斜至某一位置的侧视图。从图1至图6、图10和图11中可以看出，当主体相对于进口部从不倾斜位置滑动到倾斜位置过程中，所述开口的朝向会发生变化；主体4相对于进口部3进行滑动或进行倾斜度的调整，能使喷嘴1的出风方向在竖直平面上发生变化，以满足用户的不同需求。Fig. 10 shows a side view of the fan shown in Fig. 1 tilted forward to a certain position, and Fig. 11 shows a side view of the fan shown in Fig. 1 tilted backward to a certain position. It can be seen from Fig. 1 to Fig. 6, Fig. 10 and Fig. 11 that when the main body slides from the non-tilted position to the inclined position relative to the inlet part, the orientation of the opening will change; the main body 4 relative to the inlet part 3 Sliding or adjusting the inclination can change the air outlet direction of the nozzle 1 on the vertical plane to meet different needs of users.
图12展示了图7所示的喷嘴的替换结构。从图12中容易看出，本实施例的喷嘴与图7所示的喷嘴有所不同。在本实施例中，主体4没有与外壳体6连接的第二构件18，而进口部3还包括位于外壳体6外并与进气管15连接的第三构件20，其中，在第一构件16与第三构件20之间具有间隙，并且外壳体6有部分位于该间隙中并与第三构件20相接触。该种结构的喷嘴也能使主体4相对于进口部3进行滑动或进行倾斜度的调整，使喷嘴1的出风方向在竖直平面上发生变化。FIG. 12 shows an alternative to the nozzle shown in FIG. 7 . It can be easily seen from FIG. 12 that the nozzle of this embodiment is different from the nozzle shown in FIG. 7 . In this embodiment, the main body 4 has no second member 18 connected to the outer shell 6, and the inlet portion 3 further includes a third member 20 located outside the outer shell 6 and connected to the intake pipe 15, wherein the first member 16 There is a gap with the third member 20 , and part of the outer housing 6 is located in the gap and contacts the third member 20 . The nozzle with this structure can also make the main body 4 slide or adjust the inclination relative to the inlet part 3, so that the air outlet direction of the nozzle 1 can be changed on the vertical plane.
尽管已经展示和描述了目前认为是优选的本发明的实施例，但显而易见，本领域的技术人员可以进行各种改变和改进，而不背离由所附权利要求书所限定的本发明的范围。While there has been shown and described what are presently considered to be the preferred embodiments of the invention, it will be obvious to those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the appended claims.
