[0028] Reference Figure 2A gas valve comprises: a gas valve seat 10, which is made of a conductive material; a valve stem 20, which is rotatably mounted in the gas valve seat 10 and can move along its axis, and the valve stem 20 is made of a conductive material; a conductive member 50, which is fixed on the valve stem 20, and a channel for the conductive member 50 to move is also provided in the gas valve seat 10; a conductive sheet 40, which is arranged in the channel, and the conductive member 50 moves with the valve stem 20 and can be electrically connected to the conductive sheet 40; an insulating component, which is arranged between the conductive sheet 40 and the gas valve seat 10, and can insulate the conductive sheet 40 from the gas valve seat 10. When the valve stem 20 is pushed, the conductive member 50 will be driven together and contact the conductive sheet 40 to conduct electricity. The user only needs to push the valve stem 20 to complete the closing of the switch. At the same time, since the conductive member 50 is located inside the closed channel, it will not be disturbed by the outside world, and the insulating component insulates the conductive sheet 40 from the gas valve seat 10, so the contact between the two undoubtedly has the advantages of no need for auxiliary accessories and relatively stable contact. The conductive circuit is electrically connected to the conductive sheet 40 and the conductive member 50 respectively, so when the two are in contact, the circuit will be connected, which is equivalent to the switch being in a closed state, achieving the effect of pressing the switch.

[0029] Preferably, the conductive member 50 and the conductive sheet 40 are both made of conductive materials, and a terminal is further provided at the portion of the conductive sheet extending out of the gas valve seat 10. The terminal is used to connect to the conductive circuit. Another conductive circuit can be electrically connected to the valve stem 20, the gas valve seat 10 or the conductive member 50. Since the valve stem 20, the gas valve seat 10 and the conductive member 50 are all made of conductive materials, the three can be electrically conductive to each other, and the conductive circuit can be electrically connected to any of the three.

[0030] Preferably, the conductive member 50 is a pin made of copper or stainless steel. Copper or stainless steel are both excellent conductive materials, which can ensure that the conductive member 50 can smoothly transmit electricity.

[0031] Preferably, refer to Figure 2 and Figure 3 , a rotatable valve core 30 is also provided in the air valve seat 10, and a mounting groove 35 is also provided on the valve core 30, and the end of the conductive member 50 is inserted in the mounting groove 35; a long through hole or notch is also provided on the side wall of the mounting groove, and the conductive member 50 is located in the through hole or notch and passes through the through hole or notch. The conductive member 50 is equivalent to a pin connecting the valve stem 20 and the valve core 30. When the valve stem 20 rotates, the conductive member 50 will abut against the inner wall of the through hole or notch, thereby driving the valve core 30 to rotate together. The conductive member 50 acts as a pin, which not only does not require additional space for installing the conductive member 50, but the long through hole or notch can also provide a passage required for the movement of the conductive member 50.

[0032] Preferably, refer to Figure 2The insulating assembly includes a set of insulating rings 80 arranged on the outer periphery of the valve stem 20, and a clamping groove 83 is arranged on the insulating ring 80. The conductive sheet 40 is an annular structure and is installed in the clamping groove 83; the side wall of the clamping groove 83 close to the conductive member 50 is shorter than the other side wall, so as to allow the conductive sheet 40 in the clamping groove 83 to leak out. When the conductive member 50 moves, it will pass through the shorter side wall of the clamping groove 83 and contact the conductive sheet 40 inside it. There is a gap between the insulating ring 80 and the valve stem 20. The gap prevents the insulating ring 80 from contacting the valve stem 20, thereby avoiding interference with the insulating ring 80 when the valve stem 20 rotates. The insulating ring 80 can not only prevent the current on the conductive sheet 40 from flowing into the gas valve, but the clamping groove 83 in the insulating ring 80 can also provide a support and positioning position for the conductive sheet 40, thereby fixing the conductive sheet 40.

[0033] Preferably, refer to Figure 4 The gas valve seat 10 includes a supporting seat 12 and a connecting seat 11 connected to each other, and the insulating ring 80 is arranged in the supporting seat 12 and blocks the gap 14 at the connection between the supporting seat 12 and the connecting seat 11. The insulating ring 80 can block the gap between the supporting seat 12 and the connecting seat 11, thereby preventing impurities such as liquid from entering the interior of the supporting seat 12 or the connecting seat 11.

[0034] Further, refer to Figure 1 The support seat 12 and the connecting seat 11 are fixedly connected by bolts. The bolts clamp the two together, so that the cooperation between the two is more tight.

[0035] Preferably, refer to Figure 4 The support seat 12 is provided with a placement groove 13 at the connection seat 11, and the connection seat 11 is provided with a groove 16 at the connection with the support seat 12; the placement groove 13 and the groove 16 are connected to form a channel, and the insulating ring 80 is installed in the placement groove 13 and abuts against the notch of the groove 16. The insulating ring 80 abuts against the inner wall of the placement groove 13, and the insulating ring 80 also abuts against the notch of the groove 16. The abutting effect of the insulating ring 80 enables the insulating ring 80 to act as a seal to seal between the placement groove 13 and the groove 16, thereby preventing impurities from entering the interior of the two. The positions of the placement groove 13 and the groove 16 can be interchanged, so that the disassembly and assembly are more flexible.

[0036] Preferably, the placement groove 13 may also be arranged in the connecting seat 11 , and correspondingly, the groove 16 is arranged in the supporting seat 12 .

[0037] Preferably, refer to Figure 4, the placement groove 13 is located in the support seat 12, and the groove 16 is located in the connection seat 11; the placement groove 13 and the groove 16 are both circular grooves, and the notch diameter of the groove 16 is smaller than the notch diameter of the placement groove 13, and the outer side of the shorter side wall of the clamping groove 83 abuts against the end surface where the notch of the placement groove 13 is located. Therefore, the insulating ring 80 also abuts against the end surface where the notch of the placement groove 13 is located. The abutment of the insulating ring 80 prevents impurities from moving to the notch of the groove 16, thereby preventing impurities from entering the groove 16.

[0038] Preferably, refer to Figure 2 and Figure 3 The reset mechanism 70 includes a coil spring, which is arranged between the valve seat 10 and the valve stem 20. The two ends of the coil spring are respectively in contact with the valve seat 10 and the valve stem 20. When the valve stem 20 moves to the point where the conductive member 50 contacts the conductive sheet 40, the coil spring will be in a compressed state. When the force on the valve stem 20 is released, the coil spring will drive the valve stem 20 to rebound.

[0039] Preferably, the two ends of the coil spring are respectively in contact with the valve seat 10 and the conductive member 50. After the conductive member 50 moves into the valve seat 10 and the external force is removed, the coil spring will push the conductive member 50 to reset and drive the valve stem 20 to reset, thereby releasing the closed state of the switch.

[0040] Preferably, refer to Figure 2 The gas valve seat 10 and the valve stem 20 are both provided with steps, and the two ends of the coil spring are respectively abutted against the steps of the gas valve seat 10 and the valve stem 20. The step can provide a positioning point for the coil spring, thereby preventing it from moving.

[0041] Preferably, anti-rust oil is provided in the channel, which can effectively slow down the oxidation of the conductive sheet 40 , thereby increasing the service life of the conductive sheet 40 .

[0042] Preferably, refer to Figure 2 The valve stem 20 is also provided with a waterproof ring 90. The waterproof ring 90 can prevent moisture from entering the gas valve seat 10, thereby improving the stability of the work in the gas valve seat 10.

[0043] Preferably, the conductive member 50 may also be a hook (not shown in the figure) made of conductive material. The conductive sheet 40 is provided with a buckle groove (not shown in the figure) that matches the hook. When the hook contacts the buckle groove and continues to move forward, the hook will begin to deform and buckle into the buckle groove. The cooperation between the hook and the buckle groove can relatively fix the valve stem 20 and the conductive sheet 40, thereby ensuring the stability of the electrical connection.

[0044] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments or combinations, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
