Abstract

The present invention belongs to the technical field of temperature control valves, and in particular relates to a temperature control valve, which includes a first switch valve, a switch knob, a temperature control sensor, a mounting shell, a second switch valve, and a third switch valve. When igniting, if the battery is dead, the gas stove will not generate electric sparks. At this time, even if the switch button is rotated to turn on the first switch and the second switch, the gas stove will not ignite, that is, the temperature control sensor will not extend and the third switch valve will not open. In this case, after the second switch is closed under the action of the first volute spring, the channels at the air inlet and outlet ends are also closed accordingly. That is, the gas stove designed by the present invention can automatically cut off the gas supply of the gas stove if a child or an adult accidentally turns the switch button when the battery is dead, thereby reducing the danger to a certain extent.

Description

Technical Field

[0001] The present invention belongs to the technical field of temperature control valves, and in particular relates to a temperature control valve. Background Art

[0002] A gas stove refers to a kitchen appliance that uses gas fuels such as liquefied petroleum gas (liquid), artificial gas, and natural gas for direct heating.

[0003] When the gas stove switch is turned on, sparks will be generated and gas will be blown out to ignite; when the wind blows or soup overflows, the flame will be extinguished, and the temperature of the temperature sensor will drop; the temperature sensor will disconnect the gas of the gas stove through the power actuator, which plays a flameout protection function; but when igniting, if the battery is dead and the gas stove does not generate sparks, pressing the knob switch will cause gas to continue to blow out. At this time, as long as you do not release the button, the gas stove will not cut off the gas by itself, which is dangerous.

[0004] For commercial multi-burner gas stoves, such as those used in snack stalls, each burner needs to be controlled individually, which is very inconvenient to use. If all burners can be controlled at the same time and the size of the fire on each burner can be freely adjusted, it will be very convenient to use.

[0005] The present invention designs a temperature control valve to solve the above problems. Summary of the Invention

[0020] 1. During ignition, if the battery is dead, the gas stove will not generate sparks. At this time, even if the switch button is rotated to turn on the first switch and the second switch, the gas stove will not ignite, that is, the temperature control sensor will not extend and the third switch valve will not open. In this case, after the second switch is closed under the action of the first scroll spring, the passages at the air inlet and outlet ends are also closed accordingly. That is, the gas stove designed by the present invention can automatically shut off the gas if a child or an adult accidentally turns the switch button when the battery is dead, thereby reducing the risk to a certain extent.

[0021] 2. The temperature control valve designed in the present invention connects the first synchronous wheels between adjacent stove units through a first synchronous belt. When the switch button is rotated counterclockwise to turn on one of the stove units, the remaining stove units will also be turned on. After that, the size of each stove unit can be adjusted independently, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments or drawings are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] A temperature control valve 2, such as Figure 4 、 5 As shown, it includes a first switch valve 6, a switch knob 7, a temperature control sensor 8, a mounting shell 9, a second switch valve 10, and a third switch valve 11, wherein Figure 17 As shown, a limiting groove 52 is opened on the inner wall of the front end of the mounting shell 9. Figure 2 As shown, the mounting shell 9 is fixedly mounted on the front end of the stove 5; Figure 4 As shown, the first switch valve 6 is fixedly installed in the installation shell 9; Figure 10As shown, the front end of the first switch valve 6 outputs two electrical connectors 30 outward, and two control shafts 27 capable of controlling the opening and closing of the first switch valve 6 are output at the middle position between the front and rear ends of the first switch valve 6; one end of the driving inner rod 36 is slidably installed in the control shaft 27 at the front end of the first switch valve 6 through the cooperation of the guide block and the guide groove, and a third spring 32 is installed between the driving inner rod 36 and the control shaft 27 at the front end of the first switch valve 6; the switch knob 7 is fixedly installed on the other end of the driving inner rod 36; Figure 10 、 12 As shown, one end of the transmission sleeve 40 is fixedly mounted on the switch knob 7, and the other end of the transmission sleeve 40 is fixedly mounted with a transmission disc 43, and a second spring 31 is installed between the transmission disc 43 and the first switch valve 6; Figure 13 As shown, a telescopic inner ring 44 is fixedly mounted on the transmission disc 43, a telescopic outer sleeve 45 is slidably mounted on the telescopic inner ring 44, and a fourth spring 47 is mounted between the telescopic outer sleeve 45 and the telescopic inner ring 44; an annular electrical connecting piece 46 is fixedly mounted on the telescopic outer sleeve 45; Figure 10 As shown, the electrical connection piece 46 cooperates with the two electrical connectors 30 output from the first switch valve 6; Figure 13 As shown, a third transmission block 42 is slidably mounted on the outer circumference of the transmission sleeve 40, and a fifth spring 48 is installed between the third transmission block 42 and the transmission sleeve 40; one end of the third transmission block 42 extending from the transmission sleeve 40 has an inclined surface; the limiting rod 39 is fixedly mounted on the transmission sleeve 40, as shown Figure 17 As shown, the limit rod 39 cooperates with the limit groove 52 opened on the mounting shell 9; when the rotary switch knob 7 is not pressed, the limit rod 39 is located in the limit groove 52 and is close to the end surface of one side of the limit groove 52, and the limit groove 52 limits the counterclockwise rotation of the limit rod 39; Figure 12 As shown, the guide column 41 is fixedly mounted on the outer surface of the transmission sleeve 40, and the second support plate 38 is fixedly mounted in the mounting shell 9. Figure 16 As shown, the second support plate 38 is provided with an adjustment slot 51. Figure 15 As shown, the guide post 41 is located in the adjustment slot 51. When the control switch knob 7 rotates clockwise, the guide post 41 drives the transmission sleeve 40 to slide toward the first switch valve 6 under the guidance of the adjustment slot 51. When the control switch knob 7 rotates counterclockwise, the guide post 41 slides along the adjustment slot 51, but does not drive the transmission sleeve 40 to slide along the axial direction relative to the first switch valve 6. Figure 10 As shown, the first support plate 34 is fixedly mounted in the mounting shell 9, and the first synchronous wheel 35 is rotatably mounted on the first support plate 34, as shown in FIG. Figure 14 As shown, the fourth transmission block 49 and the fifth transmission block 50 are fixedly mounted on the inner circumference of the first synchronous wheel 35. Figure 11 、 19As shown, the fourth transmission block 49, the fifth transmission block 50 and the third transmission block 42 cooperate; the length of the fourth transmission block 49 is equal to the width of the first synchronous wheel 35, and the length of the fifth transmission block 50 is less than the width of the first synchronous wheel 35. In the initial state, the fifth transmission block 50 and the third transmission block 42 have an overlapping area in the circumferential direction. Looking from the front at the third transmission block 42, the fourth transmission block 49 and the fifth transmission block 50, the fourth transmission block 49 is located on the right side of the third transmission block 42, and the fifth transmission block 50 is located on the left side of the third transmission block 42; a second volute spring 33 is installed between the first synchronous wheel 35 and the second support plate 38.

[0045] Looking forward at the thermostatic valve 2, when the rotary switch knob 7 is not pressed, the limit rod 39 is located within the limit slot 52 and abuts against one end surface of the limit slot 52. The limit slot 52 limits the counterclockwise rotation of the limit rod 39. The limit slot 52 allows the limit rod 39 to rotate clockwise within it. That is, when the switch button is not pressed, the switch button can be manually rotated clockwise but not counterclockwise. If you want to rotate the switch button counterclockwise, you need to press the switch button first to disengage the limit rod 39 from the limit slot 52 before you can rotate it counterclockwise.

[0046] In the present invention, the first switch valve 6 has an air inlet end 12, and the third switch valve 11 has an air outlet end 17; during normal ignition, the switch button is first pressed and then rotated counterclockwise. When the switch button is pressed and moved, it will drive the transmission sleeve 40 to move, and the movement of the transmission sleeve 40 drives the transmission disk 43 to move. The movement of the transmission disk 43 drives the telescopic inner ring 44 to move. The movement of the telescopic inner ring 44 drives the telescopic outer sleeve 45 to move through the fourth spring 47. The movement of the telescopic outer sleeve 45 drives the electrical connecting piece 46 installed thereon to move, and the second spring 31 is compressed; when the electrical connecting piece 46 contacts and cooperates with the two electrical connectors 30 output from the front end of the first switch valve 6, the two electrical connectors 30 are connected to generate current; in this process, the movement of the switch button will drive the driving inner rod 36 to move relative to the control shaft 27 at the front end of the first switch valve 6, and the third spring 32 is compressed. During normal ignition, when the switch button is rotated counterclockwise, the limit rod 39 will slide out of the limit groove 52 as the transmission sleeve 40 moves. When the switch button is released after ignition, the transmission disk 43 moves and resets under the action of the second spring 31. The telescopic inner ring 44, the telescopic outer sleeve 45 and the electrical connection piece 46 installed on the transmission disk 43 will move and reset together with the transmission disk 43. The limit rod 39 drives the transmission sleeve 40 to rotate a certain angle due to the switch button, and is misaligned with the limit groove 52; therefore, the limit rod 39 will be close to the front inner wall of the mounting shell 9 after being reset together with the transmission disk 43 and the transmission sleeve 40; after resetting, the electrical connection piece 46 is disconnected from the two electrical connectors 30.

[0047] During the normal ignition counterclockwise rotation process of the switch button, the switch button is pressed before being rotated. When the switch button is pressed, the transmission sleeve 40 is driven to move, and the movement of the transmission sleeve 40 drives the third transmission block 42 installed thereon to move, so that the third transmission block 42 and the fifth transmission block 50, which originally had overlapping areas in the circumferential direction, are misaligned. Because in the initial state, when looking forward at the third transmission block 42 and the fifth transmission block 50, the fourth transmission block 49 is located on the right side of the third transmission block 42. Therefore, in the process of rotating the switch button counterclockwise after pressing the switch button, the fifth transmission block 50 is already misaligned with the third transmission block 42, so it will not affect the rotation of the third transmission block 42, that is, it will not affect the rotation of the transmission sleeve 40.

[0048] In the present invention, when the switch button is rotated counterclockwise, on the one hand, the switch button will drive the control shaft 27 at the front end of the first switch valve 6 to rotate by driving the inner rod 36 to open the first switch valve 6; on the other hand, the rotation of the switch button will drive the transmission sleeve 40 to rotate, and the transmission sleeve 40 will drive the electrical connection piece 46 to rotate through the transmission disk 43, the telescopic inner ring 44, the fourth spring 47 and the telescopic outer sleeve 45. The electrical connection piece 46 of the present invention is an annular piece. In the process of the transmission sleeve 40 being driven to rotate by the switch button, the electrical connection piece 46 that is driven to rotate together can ensure that the two electrical connectors 30 are always connected.

[0049] In the present invention, when the control shaft 27 at the front end of the first switch valve 6 is driven to rotate counterclockwise, the control shaft 27 at the rear end of the first switch valve 6 will also rotate counterclockwise. The rotation of the control shaft 27 at the rear end drives the installation shaft 20 to rotate through the second synchronous wheel 18 and the second synchronous belt 19. The rotation of the installation shaft 20 drives the first transmission wheel 21 to rotate. The first transmission wheel 21 drives the first transmission block 24 to rotate through the cooperation of the second transmission block 26 and the first transmission block 24. The second transmission wheel 23 rotates and drives the control shaft 27 of the second switch valve 10 to rotate. The first volute spring 29 is compressed, and the control shaft 27 of the second switch valve 10 rotates to open the second switch valve 10. That is, the connecting pipe 37 connecting the first switch valve 6 and the gas outlet end 17 is connected. At this time, the gas entering the first switch valve 6 from the gas inlet end 12 will be discharged from the gas outlet end 17 through the connecting pipe 37, and the gas stove is ignited. When the first and second transmission blocks 24 and 26 disengage during rotation, the second transmission block 26 loses its force on the first transmission block 24. Under the action of the first volute spring 29, the control shaft 27 of the second switch valve 10 rotates in the opposite direction. During rotation, due to the resistance exerted by the damper 28, the rotation speed is relatively slow. That is, the second switch valve 10 closes relatively slowly under the action of the first volute spring 29. During the closing process of the first one-way valve, the second transmission block 26 rotates in the opposite direction and passes through the first transmission block 24. During this process, when the second transmission block 26 contacts the first transmission block 24, the inclined surface of the first transmission block 24 causes the first transmission block 24 to move inward, compressing the first spring 25. After the second transmission block 26 passes the first transmission block 24, the inclined surface end of the first transmission block 24 moves outward under the action of the first spring 25. At this time, the first and second limit blocks return to their initial positions. The damper 28 is provided to ensure that the second switch valve 10 can close slowly, providing sufficient time for the opening of the third switch valve 11.

[0050] When the second switch valve 10 is closed under the action of the first volute spring 29, the connecting pipe 37 between the first switch valve 6 and the gas outlet end 17 is also closed. However, before that, because the gas stove is also ignited, the sensing end 4 installed on the stove top 5 is heated and the temperature is transferred to the temperature control sensor 8, causing the temperature control sensor 8 to extend, and the temperature control sensor 8 drives the rack 14 to move downward, and the rack 14 drives the gear 16 to rotate. The rotation of the gear 16 drives the control shaft 27 of the third switch valve 11 to rotate and open the third switch valve 11. Therefore, even if the second switch valve 10 is closed at this time, the gas entering the first switch valve 6 can also be discharged from the gas outlet end 17 through the third switch valve 11.

[0051] In the present invention, when the two electrical connectors 30 are connected via the electrical connector piece 46 , electric sparks are output to the gas outlet of the stove 5 for ignition.

[0052] like Figure 18As shown, the first switch valve 6, the second switch valve 10 and the third switch valve 11 in the present invention are all existing technologies. By rotating the control shaft 27 of the switch valve, the rotation of the valve core 54 in the switch valve can be controlled, that is, whether the air inlet and the air outlet of the switch valve are connected, whether the switch valve is opened and the size of the opening can be controlled.

[0053] like Figure 4 、 7 As shown, the mounting shaft 20 is rotatably mounted in the mounting housing 9, and a second synchronous wheel 18 is fixedly mounted on the mounting shaft 20 and the control shaft 27 at the rear end of the first switch valve 6. The two second synchronous wheels 18 are connected by a second synchronous belt 19; the first transmission wheel 21 is fixedly mounted on the mounting shaft 20, as shown. Figure 8 As shown, the second transmission block 26 is fixedly mounted on the outer circumference of the first transmission wheel 21; the second switch valve 10 is fixedly mounted in the mounting shell 9, and the second transmission wheel 23 is fixedly mounted on the control shaft 27 of the second switch valve 10. The first transmission block 24 and the sixth transmission block 58 are slidably mounted on the outer circumference of the second transmission wheel 23. The sixth transmission block 58 and the first transmission block 24 both have inclined surfaces, and the first spring 25 is installed between the first transmission block 24 and the sixth transmission block 58 and the second transmission wheel 23; the first transmission block 24 and the sixth transmission block 58 are located on both sides of the second transmission block 26 and cooperate with the second transmission block 26; in the initial state, the back of the first transmission block 24 and the sixth transmission block 58 at one end of the inclined surface contacts the second transmission block 26; during the opening process of the first switch valve 6, the second transmission block 26 can move the back of the first transmission block 24 or the sixth transmission block at one end of the inclined surface so that the first transmission block 24 drives the second transmission wheel 23 to rotate; the mounting sleeve 22 is fixedly mounted in the mounting shell 9, as shown Figure 9 As shown, the damper 28 is installed in the mounting sleeve 22, and the damper 28 is connected to the control shaft 27 of the second switch valve 10; a first volute spring 29 is installed between the control shaft 27 of the second switch valve 10 and the mounting sleeve 22; the third switch valve 11 is fixedly installed in the mounting shell 9, and the third switch valve 11 is connected to the first switch valve 6; the first switch valve 6 has an air inlet end 12, and the third switch valve 11 has an air outlet end 17; the first switch valve 6 and the air outlet end 17 are connected by a connecting pipe 37, and the connecting pipe 37 passes through the second switch valve 10; Figure 6 As shown, the fixing plate 13 is fixedly installed in the mounting shell 9, the upper end of the temperature control sensor 8 is fixedly installed on the fixing plate 13, and a rack 14 is fixedly installed on the lower end of the temperature control sensor 8. A gear 16 is fixedly installed on the control shaft 27 of the third switch valve 11, and the gear 16 is engaged with the rack 14; the temperature control sensor is connected to the sensing end 4 installed in the stove 5 through a connecting line 15.

[0054] like Figure 1 、 2As shown in FIG. 3 , the first synchronous wheels 35 in adjacent cooktop units 1 are connected through the first synchronous belt 3 .

[0055] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.

[0056] Implementation method: When the temperature control valve 2 designed by the present invention is used and ignition is normal, the switch button is first pressed and then rotated counterclockwise. When the switch button is pressed and moved, the transmission sleeve 40 is driven to move, and the movement of the transmission sleeve 40 drives the transmission disk 43 to move. The movement of the transmission disk 43 drives the telescopic inner ring 44 to move. The movement of the telescopic inner ring 44 drives the telescopic outer sleeve 45 to move through the fourth spring 47. The movement of the telescopic outer sleeve 45 drives the electrical connection piece 46 installed thereon to move, and the second spring 31 is compressed; when the electrical connection piece 46 contacts and cooperates with the two electrical connectors 30 output from the front end of the first switch valve 6, the two electrical connectors 30 are connected to generate current; when the switch button is rotated, the switch button drives the control shaft 27 at the front end of the first switch valve 6 to rotate by driving the inner rod 36 to open the first switch valve 6. When the control shaft 27 at the front end of the first switch valve 6 is driven to rotate, the control shaft 27 at the rear end of the first switch valve 6 will also rotate together. The rotation of the control shaft 27 at the rear end drives the installation shaft 20 to rotate through the second synchronous wheel 18 and the second synchronous belt 19. The rotation of the installation shaft 20 drives the first transmission wheel 21 to rotate. The first transmission wheel 21 drives the first transmission block 24 to rotate through the cooperation of the second transmission block 26 and the first transmission block 24, and the second transmission wheel 23 rotates, and the control shaft 27 of the second switch valve 10 rotates. The first volute spring 29 is compressed, and the second switch valve 10 controls the rotation shaft 27 to rotate so that the second switch valve 10 is opened, that is, the connecting pipe 37 connecting the first switch valve 6 and the gas outlet end 17 is connected. At this time, the gas entering the first switch valve 6 from the gas inlet end 12 will pass through the connecting pipe 37 and be discharged from the gas outlet end 17, and will be discharged from the two The spark output by the electrical connector 30 is ignited; at this time, the sensing end 4 installed on the stove top 5 is heated and transmits the temperature to the temperature control sensor 8, causing the temperature control sensor 8 to extend, and the temperature control sensor 8 drives the rack 14 to move downward, and the rack 14 drives the gear 16 to rotate. The rotation of the gear 16 drives the control shaft 27 of the third switch valve 11 to rotate to open the third switch valve 11. At the same time, the second switch valve 10 is closed under the action of the first volute spring 29; at this time, the gas entering the first switch valve 6 can also be discharged from the gas outlet end 17 through the third switch valve 11.

[0057] During ignition, if the battery is dead, the gas stove will not generate sparks. At this time, even if the switch button is rotated to turn on the first switch and the second switch, the gas stove will not ignite, that is, the temperature control sensor 8 will not extend or retract, and the third switch valve 11 will not open. In this case, after the second switch is closed under the action of the first volute spring 29, the channels of the air inlet end 12 and the air outlet end 17 are also closed accordingly. That is, when the gas stove designed by the present invention has a dead battery, if a child or an adult accidentally turns the switch button, the gas of the gas stove can also be cut off by itself, which reduces the danger to a certain extent.

[0058] like Figure 19 As shown, when the switch button is rotated clockwise, the switch button drives the transmission sleeve 40 to rotate, and the rotation of the transmission sleeve 40 drives the third transmission block 42 to rotate; because in the initial state, the fifth transmission block 50 and the third transmission block 42 have an overlapping area in the circumferential direction, looking from the front at the third transmission block 42, the fourth transmission block 49 and the fifth transmission block 50, the fourth transmission block 49 is located on the right side of the third transmission block 42, so at this time the straight surface of the third transmission block 42 cooperates with the fourth transmission block 49, and the rotation of the third transmission block 42 will drive the fourth transmission block 49 to rotate, and the rotation of the third transmission block 42 drives the first synchronous wheel 35 to rotate, and the rotation of the first synchronous wheel 35 drives the first synchronous wheel 35 in the adjacent cooktop unit 1 to rotate; when the first synchronous wheel 35 in the adjacent cooktop unit 1 rotates, it will drive the corresponding third transmission block 42 to rotate through the fifth transmission block 50 installed thereon, that is, drive the corresponding transmission sleeve 40 to rotate, and the rotation of the transmission sleeve 40 drives the switch button to rotate on the one hand, and the rotation of the switch button drives the front end control shaft 27 of the first switch valve 6 to rotate by driving the inner rod 36, as shown Figure 18 As shown, at the beginning, the vent hole of the valve core 54 in the first switch valve 6 is misaligned with the air inlet and the air outlet of the first switch valve 6, so the first switch valve 6 is in a closed state during this process; on the other hand, the transmission sleeve 40 will drive the guide column 41 installed thereon to rotate during the rotation process. At this time, the transmission sleeve 40 rotates clockwise. Under the action of the adjustment slide 51, the guide column 41 will drive the transmission sleeve 40 to move inward. On the one hand, the transmission sleeve 40 will drive the electrical connecting piece 46 to move through the transmission disc 43, the telescopic inner ring 44, and the telescopic outer sleeve 45. On the other hand, the movement of the transmission sleeve 40 will drive the third transmission block 42 to move, as shown in FIG. Figure 20As shown, after the electrical connection piece 46 contacts the two electrical connectors 30, the third transmission block 42 has not yet disengaged from the corresponding fifth transmission block 50. At this time, the third transmission block 42 continues to be driven to rotate, and the transmission sleeve 40 continues to move. Since the electrical connection piece 46 has contacted the two electrical connectors 30, the telescopic outer sleeve 45 is restricted from moving, so the fourth spring 47 between the telescopic inner ring 44 and the telescopic outer sleeve 45 is compressed; that is, at this time, the contact between the electrical connection piece 46 and the electrical connector 30 will not affect the continued rotation of the corresponding third transmission block 42; during the continued rotation of the third transmission block 42, the first switch valve 6 will open from the closed state for ventilation, and then the third transmission block 42 will continue to rotate. The third transmission block 42 continues to be driven to rotate until the third transmission block 42 is disengaged from the fifth transmission block 50, at which point the third transmission block 42 stops rotating. During this process, the switch button is driven to rotate 90 degrees, and all the stove units 1 are ignited and turned to the maximum. The reason for the design of the third transmission block 42 being disengaged from the fifth transmission block 50 is that in subsequent use, the stoves 5 can be adjusted automatically according to their requirements for fire size, either to reduce the size or to increase the size after reducing the size. That is, such a design will not affect other stove units 1 due to the small opening range of all stoves 5 when they are turned on at the same time. When a single stove is subsequently adjusted to increase the size, the transmission of the first synchronous belt 3 during the counterclockwise rotation of the switch button will not affect the other stove units 1.

[0059] In the process of the fifth transmission block 50 of the adjacent stove 5 shifting the third transmission block 42, the control shaft 27 at the rear end of the first switch valve 6 rotates clockwise through the second synchronous wheel 18 and the second synchronous belt 19 to drive the installation shaft 20 to rotate. The rotation of the installation shaft 20 drives the first transmission wheel 21 to rotate. The first transmission wheel 21 shifts the first transmission block 24 through the cooperation of the second transmission block 26 and the sixth transmission block 58 to drive the second transmission wheel 23 to rotate. The rotation of the second transmission wheel 23 drives the control shaft 27 of the second switch valve 10 to rotate. The first volute spring 29 is stretched, and the control shaft 27 of the second switch valve 10 rotates clockwise to open the second switch valve 10, that is, the connecting pipe 37 connecting the first switch valve 6 and the gas outlet end 17 is connected. At this time, the gas entering the first switch valve 6 from the air inlet end 12 will be discharged from the gas outlet end 17 through the connecting pipe 37, and the gas stove is ignited. When the sixth transmission block 58 and the second transmission block 26 disengage during rotation, the second transmission block 26 loses its force on the sixth transmission block 58. Under the action of the first volute spring 29, the control shaft 27 of the second switch valve 10 rotates in the opposite direction. During rotation, due to the resistance exerted by the damper 28, the rotation speed is relatively slow. That is, the second switch valve 10 closes relatively slowly under the action of the first volute spring 29. During the closing process of the first one-way valve, due to the reverse rotation of the second transmission block 26, it passes through the sixth transmission block 58. During this process, when the second transmission block 26 contacts the sixth transmission block 58, the inclined surface of the sixth transmission block 58 causes the sixth transmission block 58 to move inward, compressing the first spring 25. After the second transmission block 26 passes the sixth transmission block 58, the inclined surface end of the sixth transmission block 58 moves outward under the action of the first spring 25. At this time, the sixth and second limit blocks return to their initial states. The damper 28 is provided to ensure that the second switch valve 10 can close slowly, providing sufficient time for the opening of the third switch valve 11.

[0060] When the adjacent stove 5 is turned on, each switch button can be adjusted up or down and can also be turned off separately. The process of turning off the stove 5 is described below.

[0061] In the initial state, one of the stoves 5 is closed, and the three stoves 5 are opened to different degrees. The third transmission block 42 in the closed stove 5 and the stove 5 with a smaller opening degree returns to the initial position, and the fourth transmission block 49 is located on the right side of the third transmission block 42.

[0062] When the stove 5 with the smaller opening degree among the stoves 5 that are not closed is closed, the third transmission block 42 rotates counterclockwise to return to the initial state.

[0063] When the stove 5 that is most opened among the unclosed stoves 5 is closed, the first synchronous wheel 35, under the action of the corresponding second spiral spring 33, causes its fourth transmission block 49 to be close to the third transmission block 42 and gradually reset counterclockwise. During the resetting process, the fifth transmission blocks 50 of other stoves 5 gradually approach the third transmission block 42. When this stove 5 is completely closed, the fifth transmission blocks 50 of all stoves 5 pass over the inclined surface of the corresponding third transmission block 42 of their respective stoves 5 and reach the left side of the third transmission block 42. The third transmission block 42 slides out and resets again under the action of the fifth spring 48, completing the reset.
