请参照图1与图2，本发明实施例提供一种新型节能燃气灶调节阀体装置，包括：Referring to FIG. 1 and FIG. 2 , an embodiment of the present invention provides a novel energy-saving gas stove regulating valve device, including:

一截止阀1，在该截止阀1上形成有一进气口11；a shut-offvalve 1, and anair inlet 11 is formed on the shut-offvalve 1;

一脉冲阀3，该脉冲阀3内具有一上腔体31与一下腔体32，在该上腔体 31内设置有一骨架33、设置于骨架33内侧且插入下腔体32内的一铁芯34、套设于骨架33外围的一线圈35、设置于线圈35一端且位于铁芯34外围的一永磁铁36、设置于下腔体32内且连接于铁芯34端部的一铁芯帽37、及套设于铁芯34外围且位于下腔体32内壁与铁芯帽37之间的一弹簧38，在该下腔体32内具有一第一阀口321，该铁芯帽37端部正对于第一阀口321设置；在该比例阀2与下腔体32之间形成有一第二通气口322，同时，在脉冲阀3上形成有一出气口12。Apulse valve 3, thepulse valve 3 has anupper cavity 31 and alower cavity 32, askeleton 33 is arranged in theupper cavity 31, and an iron core is arranged inside theskeleton 33 and inserted into thelower cavity 32 34. Acoil 35 sleeved on the periphery of theskeleton 33, apermanent magnet 36 disposed on one end of thecoil 35 and located on the periphery of theiron core 34, and an iron core cap disposed in thelower cavity 32 and connected to the end of theiron core 34 37, and aspring 38 sleeved on the periphery of theiron core 34 and located between the inner wall of thelower cavity 32 and theiron core cap 37, afirst valve port 321 is provided in thelower cavity 32, and theiron core cap 37 ends Asecond air port 322 is formed between theproportional valve 2 and thelower cavity 32 , and anair outlet 12 is formed on thepulse valve 3 at the same time.

本实施例截止阀1作为总阀，用于对进气进行控制。具体的，由进气口 11进入的燃气，由截止阀1对燃气是否能通过第一通气口21进入比例阀2 进行控制。而对于截止阀1的具体结构与工作原理，与本领域中常规的截止阀结构与原理相同。The cut-offvalve 1 in this embodiment is used as a master valve to control the intake air. Specifically, the gas entering through theair inlet 11 is controlled by the shut-offvalve 1 to control whether the gas can enter theproportional valve 2 through thefirst ventilation port 21. The specific structure and working principle of the cut-offvalve 1 are the same as those of conventional cut-off valves in the art.

比例阀2用于对灶具火力大小进行调节。而对于比例阀2的具体结构与工作原理，与本领域中常规的比例阀结构与原理相同。Theproportional valve 2 is used to adjust the fire power of the cooker. The specific structure and working principle of theproportional valve 2 are the same as those of the conventional proportional valve in the art.

脉冲阀3用于对灶具外环火的开启与关闭进行控制。具体的，在脉冲阀 3打开时，外环火开启点燃；在脉冲阀3关闭时，外环火关闭熄灭，而只剩下中心火。Thepulse valve 3 is used to control the opening and closing of the outer ring fire of the cooker. Specifically, when thepulse valve 3 is opened, the outer ring fire is opened and ignited; when thepulse valve 3 is closed, the outer ring fire is closed and extinguished, and only the center fire is left.

本实施例脉冲阀3的工作原理为：The working principle of thepulse valve 3 in this embodiment is:

当需要打开外环火时，通过控制电路向线圈35输入一方向电压，电压可以设定为正电压，也可以设定为负电压，线圈35通电后产生磁场，且线圈 35的磁极与永磁铁36的磁极相同，则线圈35产生的磁场与永磁铁36的磁场叠加，从而对铁芯34产生强磁吸力，该强磁吸力使得铁芯34瞬间朝远离第一阀口321的方向移动，压缩弹簧38，则此时，如图2所示，第一阀口321 打开，燃气可从第一阀口321通过，外环火打开点燃。接着，控制电路停止向线圈35输入电压，线圈35产生的磁场消失，而永磁铁36持续磁化铁芯 34，维持对铁芯34的磁吸力，使得铁芯34静止不动，则此时，第一阀口321 持续打开，外环火维持打开状态。由此可知，在维持第一阀口321打开状态，即外环火维持打开状态时，不需要给脉冲阀3通电，脉冲阀3处于断电状态，因此，大幅降低了电能的消耗。When the outer ring fire needs to be turned on, a voltage in one direction is input to thecoil 35 through the control circuit, and the voltage can be set to a positive voltage or a negative voltage. If the magnetic poles of 36 are the same, the magnetic field generated by thecoil 35 and the magnetic field of thepermanent magnet 36 are superimposed, thereby generating a strong magnetic attraction force on theiron core 34, which makes theiron core 34 move away from thefirst valve port 321 instantaneously, compressing Thespring 38, then, as shown in FIG. 2, thefirst valve port 321 is opened, the gas can pass through thefirst valve port 321, and the outer ring fire is opened and ignited. Then, the control circuit stops inputting voltage to thecoil 35, the magnetic field generated by thecoil 35 disappears, and thepermanent magnet 36 continues to magnetize theiron core 34, maintaining the magnetic attraction force to theiron core 34, so that theiron core 34 is stationary, then at this time, the firstA valve port 321 remains open, and the outer ring fire remains open. It can be seen that when thefirst valve port 321 is kept open, that is, when the outer ring fire is kept open, it is not necessary to energize thepulse valve 3, and thepulse valve 3 is in a power-off state, thus greatly reducing the power consumption.

当需要关闭外环火时，通过控制电路向线圈35输入反向电压，此处的电压与上述打开外环火时输入的电压正好相反，线圈35通电后产生磁场，且线圈35的磁极与永磁铁36的磁极相反，则线圈35产生的磁场抵消掉永磁铁36对铁芯34的磁吸力，在弹簧38的弹性恢复力作用下，铁芯34朝第一阀口321方向移动，铁芯帽37堵住第一阀口321，则此时，如图3所示，第一阀口321关闭，燃气无法从第一阀口321通过，外环火关闭熄灭。接着，控制电路停止向线圈35输入电压，线圈35产生的磁场消失，而永磁铁36对铁芯34的磁吸力无法触发铁芯34发生移动，则铁芯34维持静止状态，则此时，第一阀口321持续关闭，外环火维持关闭状态。由此可知，在维持第一阀口 321关闭状态，即外环火维持关闭状态时，不需要给脉冲阀3通电，脉冲阀3 处于断电状态，因此，大幅降低了电能的消耗。When the outer ring fire needs to be closed, a reverse voltage is input to thecoil 35 through the control circuit, and the voltage here is exactly opposite to the voltage input when the outer ring fire is turned on. The magnetic poles of themagnet 36 are opposite, the magnetic field generated by thecoil 35 cancels the magnetic attraction force of thepermanent magnet 36 to theiron core 34, and under the action of the elastic restoring force of thespring 38, theiron core 34 moves toward thefirst valve port 321, and theiron core cap 37 blocks thefirst valve port 321, then at this time, as shown in FIG. 3, thefirst valve port 321 is closed, the gas cannot pass through thefirst valve port 321, and the outer ring fire is closed and extinguished. Then, the control circuit stops inputting voltage to thecoil 35, the magnetic field generated by thecoil 35 disappears, and the magnetic attraction force of thepermanent magnet 36 to theiron core 34 cannot trigger theiron core 34 to move, so theiron core 34 maintains a static state, and at this time, the firstA valve port 321 is continuously closed, and the outer ring fire remains closed. It can be seen that when thefirst valve port 321 is kept closed, that is, when the outer ring fire is kept closed, it is not necessary to energize thepulse valve 3, and thepulse valve 3 is in a power-off state, thus greatly reducing the power consumption.

本实施例控制电路如图7所示，用于向线圈35输入正反向电压。由控制电路向线圈35输入正好相反的电压，使得在线圈35通电产生磁场后，实现两种不同的功能：一是，线圈35的磁极与永磁铁36的磁极相同，由此，线圈35产生的磁场与永磁铁36的磁场叠加，从而对铁芯34产生强磁吸力，该强磁吸力使得铁芯34瞬间朝远离第一阀口321的方向移动，则第一阀口321 打开；二是，线圈35的磁极与永磁铁36的磁极相反，由此，线圈35产生的磁场抵消掉永磁铁36对铁芯34的磁吸力，在弹簧38的弹性恢复力作用下，铁芯34朝第一阀口321方向移动，铁芯帽37堵住第一阀口321，则此第一阀口321关闭。The control circuit of this embodiment is shown in FIG. 7 , and is used to input forward and reverse voltages to thecoil 35 . The control circuit inputs the exact opposite voltage to thecoil 35, so that after thecoil 35 is energized to generate a magnetic field, two different functions are realized: First, the magnetic pole of thecoil 35 is the same as the magnetic pole of thepermanent magnet 36. The magnetic field and the magnetic field of thepermanent magnet 36 are superimposed, thereby producing a strong magnetic attraction force on theiron core 34, and the strong magnetic attraction force makes theiron core 34 move in a direction away from thefirst valve port 321 instantaneously, then thefirst valve port 321 is opened; second, The magnetic pole of thecoil 35 is opposite to the magnetic pole of thepermanent magnet 36, thus, the magnetic field generated by thecoil 35 cancels the magnetic attraction force of thepermanent magnet 36 to theiron core 34, under the action of the elastic restoring force of thespring 38, theiron core 34 moves toward the first valve Theport 321 moves in the direction, theiron core cap 37 blocks thefirst valve port 321, and thefirst valve port 321 is closed.

由上述可知，本实施例通过增设了永磁铁36的脉冲阀3结构设计，配合上可向线圈提供正反向电压的控制电路，只需要在脉冲阀3打开与关闭两个动作时向其通电，而在脉冲阀3维持工作时无需向其通电，由此，大幅降低了电能的消耗。因此，使得整个调节阀体装置功率降低，发热减少，并可选用较小功率的变压器，减少成本。As can be seen from the above, in this embodiment, thepulse valve 3 with thepermanent magnet 36 is added in the structural design, and the control circuit that can provide forward and reverse voltages to the coil is matched, and it only needs to be energized when thepulse valve 3 is opened and closed. , and there is no need to energize thepulse valve 3 when it keeps working, thereby greatly reducing the power consumption. Therefore, the power of the entire regulating valve body device is reduced, the heat generation is reduced, and a transformer with a lower power can be selected to reduce the cost.

在打开脉冲阀3时，铁芯34因受到强磁吸力上移，为了对铁芯34进行定位，本实施例在所述上腔体31内侧上壁设置有位于铁芯34正上方的一定位件39，对于定位件39的安装，本实施例在所述定位件39上端设置有卡入上腔体31内侧上壁的一安装凸块393。具体的，如图2、图3与图6所示，在该定位件39朝向铁芯34的一端部凸设有一定位凸台391，在该定位凸台 391上凹设有一定位槽392。同时，如图5所示，在所述铁芯34靠近定位件39的一端部上凹设有供定位凸台391卡入的一凹槽341，在该凹槽341内设置有与定位槽392相对应的一定位凸起342。在铁芯34因受到强磁吸力上移时，铁芯34的定位凸起342卡入定位件39的定位槽392中，定位件39的定位凸台391卡入铁芯34的凹槽341中，由此，对铁芯34进行定位，防止其偏移。When thepulse valve 3 is opened, theiron core 34 moves upward due to the strong magnetic attraction force. In order to position theiron core 34 , in this embodiment, a position located directly above theiron core 34 is provided on the inner upper wall of theupper cavity 31 in this embodiment. For the installation of the positioningmember 39, in this embodiment, aninstallation bump 393 is provided on the upper end of the positioningmember 39 to be snapped into the upper wall of the inner side of theupper cavity 31. Specifically, as shown in FIG. 2 , FIG. 3 and FIG. 6 , apositioning boss 391 is protruded from one end of the positioningmember 39 facing theiron core 34 , and apositioning groove 392 is recessed on thepositioning boss 391 . At the same time, as shown in FIG. 5 , agroove 341 is recessed on one end of theiron core 34 close to the positioningmember 39 for thepositioning boss 391 to be inserted into, and apositioning groove 392 is provided in the groove 341 Acorresponding positioning protrusion 342 . When theiron core 34 moves upward due to the strong magnetic attraction force, the positioningprotrusions 342 of theiron core 34 are inserted into thepositioning grooves 392 of the positioningmember 39 , and thepositioning bosses 391 of the positioningmember 39 are inserted into thegrooves 341 of theiron core 34 . , thereby positioning theiron core 34 and preventing it from shifting.

为了使铁芯34在发生动作时，能够竖直上下移动，本实施例在所述上腔体31内纵向设置有位于骨架33内的一导向轴套40，所述铁芯34与定位件 39设置于导向轴套40内。则铁芯34在发生动作时，能够在导向轴套40内竖直上下移动。In order to make theiron core 34 move vertically up and down when it is in action, in this embodiment, aguide bushing 40 is longitudinally arranged in theframe 33 in theupper cavity 31 . Theiron core 34 and the positioningmember 39 It is arranged in theguide shaft sleeve 40 . Then, theiron core 34 can move vertically up and down in theguide bushing 40 when the action occurs.

对于永磁铁36的安装，本实施例在所述骨架33下端形成有一容置槽 331，所述永磁铁36设置于容置槽331内，如图2与图4所示。For the installation of thepermanent magnet 36, in this embodiment, anaccommodating groove 331 is formed at the lower end of theframe 33, and thepermanent magnet 36 is arranged in theaccommodating groove 331, as shown in FIG. 2 and FIG. 4 .

对于弹簧38的安装，本实施例在所述下腔体32内侧顶部向下凸设有一上限位凸台323，在该铁芯帽37上设置有位于上限位凸台323正下方的一下限位凸台371，所述弹簧38上端套设于上限位凸台323外围，下端套设于下限位凸台371外围。在上限位凸台323与下限位凸台371的配合作用下，对弹簧38的安装位置、及弹性形变范围进行限制，利于在关闭脉冲阀3时，由弹簧38的弹性恢复力能够快速作用于铁芯34，使得铁芯34能够快速朝第一阀口321方向移动，关闭第一阀口321。For the installation of thespring 38 , in this embodiment, anupper limit boss 323 is protruded downward on the top of the inner side of thelower cavity 32 , and a lower limit is located directly below theupper limit boss 323 on theiron core cap 37 . For theboss 371 , the upper end of thespring 38 is sleeved on the periphery of theupper limit boss 323 , and the lower end is sleeved on the periphery of thelower limit boss 371 . Under the cooperative action of theupper limit boss 323 and thelower limit boss 371 , the installation position of thespring 38 and the elastic deformation range are limited, which is beneficial for the elastic restoring force of thespring 38 to quickly act on thepulse valve 3 when thepulse valve 3 is closed. Theiron core 34 enables theiron core 34 to quickly move toward thefirst valve port 321 to close thefirst valve port 321 .

本实施例灶具调节阀体装置的工作原理为：打开灶具时，截止阀1、比例阀2与脉冲阀3全打开，接着，通过比例阀2可调节火力大小。当调节火力小到设定值时，给个脉冲信号给控制电路，由控制电路向线圈35通电，则脉冲阀3关掉，外环火熄灭，只剩下中心火；当通过比例阀2调节火力大到设定值时，给个脉冲信号给控制电路，由控制电路向线圈35通电，则脉冲阀 3打开，外环火点燃。The working principle of the adjusting valve body device of the cooker in this embodiment is as follows: when the cooker is turned on, the cut-offvalve 1 , theproportional valve 2 and thepulse valve 3 are fully opened, and then theproportional valve 2 can adjust the fire power. When the adjusted fire power is small to the set value, a pulse signal is given to the control circuit, and the control circuit is energized to thecoil 35, then thepulse valve 3 is turned off, the outer ring fire is extinguished, and only the center fire is left; When the fire power reaches the set value, a pulse signal is given to the control circuit, and the control circuit energizes thecoil 35, thepulse valve 3 is opened, and the outer ring fire is ignited.

本发明还提供了基于上述新型节能燃气灶调节阀体装置的外环火控制方法，包括以下步骤：The present invention also provides an outer ring fire control method based on the above-mentioned novel energy-saving gas stove regulating valve body device, comprising the following steps:

(1)打开外环火：(1) Open the outer ring fire:

(1.1)通过控制电路向线圈35输入一方向电压，线圈35通电后产生磁场，且线圈35的磁极与永磁铁36的磁极相同，则线圈35产生的磁场与永磁铁36的磁场叠加，从而对铁芯34产生强磁吸力，该强磁吸力使得铁芯34 瞬间朝远离第一阀口321的方向移动，压缩弹簧38，则此时，第一阀口321 打开，外环火打开；(1.1) Input a voltage in one direction to thecoil 35 through the control circuit, after thecoil 35 is energized, a magnetic field is generated, and the magnetic pole of thecoil 35 is the same as the magnetic pole of thepermanent magnet 36, then the magnetic field generated by thecoil 35 and the magnetic field of thepermanent magnet 36 are superimposed, so that the Theiron core 34 generates a strong magnetic attraction, which makes theiron core 34 move in a direction away from thefirst valve port 321 instantaneously, compressing thespring 38, then at this time, thefirst valve port 321 is opened, and the outer ring fire is opened;

(1.2)接着，控制电路停止向线圈35输入电压，线圈35产生的磁场消失，而永磁铁36持续磁化铁芯34，维持对铁芯34的磁吸力，使得铁芯34 静止不动，则此时，第一阀口321持续打开，外环火维持打开状态；(1.2) Next, the control circuit stops inputting voltage to thecoil 35, the magnetic field generated by thecoil 35 disappears, and thepermanent magnet 36 continues to magnetize theiron core 34, maintaining the magnetic attraction to theiron core 34, so that theiron core 34 is stationary, then this , thefirst valve port 321 continues to open, and the outer ring fire remains open;

(2)关闭外环火：(2) Close the outer ring fire:

(2.1)通过控制电路向线圈35输入反向电压，线圈35通电后产生磁场，且线圈35的磁极与永磁铁36的磁极相反，则线圈35产生的磁场抵消掉永磁铁36对铁芯34的磁吸力，在弹簧38的弹性恢复力作用下，铁芯34朝第一阀口321方向移动，铁芯帽37堵住第一阀口321，则此时，第一阀口321关闭，外环火关闭；(2.1) Input a reverse voltage to thecoil 35 through the control circuit, thecoil 35 generates a magnetic field after being energized, and the magnetic pole of thecoil 35 is opposite to the magnetic pole of thepermanent magnet 36, then the magnetic field generated by thecoil 35 cancels thepermanent magnet 36 to theiron core 34. Magnetic attraction, under the action of the elastic restoring force of thespring 38, theiron core 34 moves toward thefirst valve port 321, and theiron core cap 37 blocks thefirst valve port 321, then at this time, thefirst valve port 321 is closed, and the outer ring fire off;

(2.2)接着，控制电路停止向线圈35输入电压，线圈35产生的磁场消失，而永磁铁36对铁芯34的磁吸力无法触发铁芯34发生移动，则铁芯34 维持静止状态，则此时，第一阀口321持续关闭，外环火维持关闭状态。(2.2) Next, the control circuit stops inputting voltage to thecoil 35, the magnetic field generated by thecoil 35 disappears, and the magnetic attraction force of thepermanent magnet 36 to theiron core 34 cannot trigger theiron core 34 to move, then theiron core 34 maintains a static state, then this , thefirst valve port 321 is continuously closed, and the outer ring fire remains closed.

其中，所述步骤(1)与步骤(2)无先后顺序。Wherein, the step (1) and the step (2) are in no order.

由上述可知，本实施例通过脉冲阀3的特殊结构设计，并由控制电路向线圈提供正反向电压，则只需要在脉冲阀3打开与关闭两个动作时向其通电，而在脉冲阀3维持工作时无需向其通电，由此，大幅降低了电能的消耗。因此，使得整个调节阀体装置功率降低，发热减少，并可选用较小功率的变压器，减少成本。It can be seen from the above that in this embodiment, through the special structural design of thepulse valve 3, and the control circuit provides forward and reverse voltages to the coil, it is only necessary to energize thepulse valve 3 when it opens and closes, while thepulse valve 3 needs to be energized when it is opened and closed. 3 There is no need to energize it to maintain operation, thereby greatly reducing power consumption. Therefore, the power of the entire regulating valve body device is reduced, the heat generation is reduced, and a transformer with a lower power can be selected to reduce the cost.

以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故采用与本发明上述实施例相同或近似的技术特征，而得到的其他结构，均在本发明的保护范围之内。The above descriptions are only preferred embodiments of the present invention, and do not limit the technical scope of the present invention. Therefore, other structures obtained by adopting the same or similar technical features as the above-mentioned embodiments of the present invention are all within the scope of the present invention. within the scope of protection.
