[0030] Reference Figures 1 to 4 A gas valve with precise on / off triggering includes a valve body 100 and a trigger switch 200. The valve body 100 includes a valve body 110 and a valve spindle 120 disposed on the valve body 110. The valve spindle 120 is used to open and close the gas valve. The valve body 110 has an integrally formed switch mounting portion 111, and a switch mounting position is provided beside the switch mounting portion 111. The valve spindle 120 has an integrally formed linkage portion 121. The trigger switch 200 is disposed at the switch mounting position and connected and fixed to the switch mounting portion 111. The trigger switch 200 has a trigger portion 210. When the valve spindle 120 is actuated, the trigger portion 210 is triggered by the linkage portion 121.

[0031] In the aforementioned gas valve, the trigger switch 200 is connected and fixed to the switch mounting part 111, which is integrally formed with the valve body 110. At the same time, the valve main shaft 120 is provided with an integrally formed trigger part 210, thereby reducing intermediate parts, avoiding error accumulation, improving the accuracy of the switch being triggered, and reducing the occurrence of incomplete triggering.

[0032] In this embodiment, the gas valve further includes a connecting seat 300, which is fixed to the switch mounting portion 111. The connecting seat 300 is provided with a mounting groove 310 adapted to the trigger switch 200, and the trigger switch 200 is disposed in the mounting groove 310. With the above structure, the trigger switch 200 can be further adapted and installed through the mounting groove 310 of the connecting seat 300, resulting in more stable installation and better protection of the trigger switch 200.

[0033] In this embodiment, the trigger switch 200 abuts against the switch mounting portion 111 via a connecting seat 300, which is an insulating component. Since the valve body 110 is generally made of metal, by making the connecting seat 300 an insulating component, the insulation between the trigger switch 200 and the valve body 110 can be effectively guaranteed, improving the safety of the gas valve. In this embodiment, the connecting seat 300 can be made of materials such as plastic, rubber, or fiberglass to achieve insulation.

[0034] In this embodiment, a plurality of terminals 220 are provided on one end face of the trigger switch 200, and a cover plate 320 is provided on the connector 300. The cover plate 320 is provided on the end of the trigger switch 200 where the terminals 220 are provided, and the cover plate 320 extends to cover the switch mounting portion 111. With the above structure, by providing the cover plate 320 to cover the switch mounting portion 111, the wires are less likely to come into contact with the switch mounting portion 111 after the trigger switch 200 is wired, thereby effectively ensuring mutual insulation.

[0035] In this embodiment, the cover plate 320 is provided with a plurality of extension pieces 321, which cover the trigger switch 200 and extend between and beside the terminals 220. This structure increases the fit between the connector 300 and the trigger switch 200, and the extension pieces 321 also increase the creepage distance.

[0036] In this embodiment, the switch mounting portion 111 is provided with a mounting hole 1111. Fasteners 400 pass through the trigger switch 200 and the connecting seat 300. The fasteners 400 are connected to the mounting hole 1111 and lock the trigger switch 200 and the connecting seat 300 together to the switch mounting portion 111. Using the above structure, the trigger switch 200 and the connecting seat 300 can be fixed together by the fasteners 400, resulting in a simple structure and convenient assembly.

[0037] In one embodiment, the fastener 400 is a screw, so the mounting hole 1111 of the switch mounting part 111 can be a screw hole; in other embodiments, the fastener 400 can also be a combination of bolts and nuts or a rivet, so the mounting hole 1111 can be a common through hole. In one embodiment, two sets of mounting holes 1111 and fasteners 400 are provided, so as to securely fix the device; it is conceivable that in other embodiments, the mounting holes 1111 and fasteners 400 can also be provided in other quantities and are not limited to the above-described embodiments.

[0038] It is conceivable that in other embodiments, the structure described above is not limited to fixing the connector 300 and the trigger switch 200; for example, the components can be fixed by plugging or snapping. It is understood that in some embodiments, the connector 300 may not be provided, and the trigger switch 200 may be directly fixed to the switch mounting portion 111; the specific configuration can be determined according to the actual situation.

[0039] In one embodiment, the valve body 110 includes a front seat and a rear seat, which are fixed to each other. The switch mounting part 111 is integrally formed with the front seat, and the valve spindle 120 is pivotally mounted on the front seat.

[0040] In this embodiment, the connecting seat 300 includes a base plate 330, a left side plate 340, a right side plate 350, and a lower side plate 360. The left side plate 340, right side plate 350, and lower side plate 360 ​​are respectively connected to the left, right, and lower sides of the base plate 330 and enclose to form a mounting groove 310. The connecting seat 300 described above has a simple structure, is easy to implement, and provides stable positioning for the trigger switch 200. In this embodiment, the cover plate 320 is connected to the upper end of the base plate 330.

[0041] In this embodiment, the valve spindle 120 passes through the valve body 110, and the valve body 110 is provided with a default portion 112 that allows the linkage part 121 of the valve spindle 120 to protrude from the default portion 112 of the valve body 110. The trigger switch 200 is provided with a trigger part 210, one end of which extends into the default portion 112. With the above structure, direct linkage between the trigger switch 200 and the valve spindle 120 can be easily achieved, and the overall structure is compact.

[0042] In this embodiment, the valve spindle 120 is configured to move axially and rotate. The linkage part 121 is a sloping step disposed on the outer periphery of the valve spindle 120. The trigger part 210 of the trigger switch 200 is a pressing structure, and the trigger part 210 is within the movement range of the sloping step when the valve spindle 120 moves axially. When the valve spindle 120 moves axially, the trigger part 210 of the trigger switch 200 can be pressed down directly by the sloping step, thereby triggering the switch. The linkage part 121 of the valve spindle 120 uses the above-described structure to achieve triggering. The structure of the valve spindle 120 is simple and easy to manufacture and implement.

[0043] In one embodiment, the trigger switch 200 may be a tactile switch, thus the trigger part 210 is a press-type structure. In another embodiment, axial movement and rotation can be achieved by providing a pivot hole in the valve body 110, allowing the valve main shaft 120 to pivot and slide within the pivot hole.

[0044] It is conceivable that in other embodiments, the linkage between the valve spindle 120 and the trigger switch 200 is not limited to the structure described above. For example, the trigger switch 200 may be a contact switch, and the valve spindle 120 may simply be a protrusion at a matching position. It is understood that the trigger switch 200 can be selected according to appropriate needs, such as a push-button type, a contact type, or a toggle type. The valve spindle 120 can be configured with a trigger part 210 corresponding to the type of the trigger switch 200, which may be the aforementioned inclined step, protrusion, or toggle handle.

[0045] In this embodiment, the valve body 110 is provided with a gas supply pipe section 113 for gas inlet and outlet. The gas supply pipe section 113 includes an integrally formed straight section 1131 and a vertical section 1132. One end of the straight section 1131 is connected to the valve body 110, and the other end is provided with a first gas inlet. One end of the vertical section 1132 is connected to the straight section 1131, and the vertical section 1132 is perpendicular to the straight section 1131. The other end of the vertical section 1132 is provided with a second gas inlet. With the above structure, the gas supply pipe section 113 integrates both the straight section 1131 and the vertical section 1132, allowing selection of the corresponding gas inlet for external connection, while unused gas inlets can be sealed, thus facilitating connection in different directions.

[0046] In this embodiment, the gas inlet can be sealed by the sealing head 114. In this embodiment, there are two gas supply pipes 113, which can be used for gas input and gas output respectively.

[0047] In this embodiment, the trigger switch 200 can be used for ignition, or in some embodiments, it can be used for valve action detection, which can be set as needed.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
