In a specific embodiment, the gas stove is provided with a plurality of firepower adjustment buttons 114, and the plurality of firepower adjustment buttons 114 are in one-to-one correspondence with the plurality of firepower modes. For example, the gas stove is provided with three firepower adjustment buttons 114, which are a first firepower adjustment button, a second firepower adjustment button, and a third firepower adjustment button, respectively, and the corresponding firepower modes are a fire mode, a medium fire mode, and a small fire mode. When the first firepower adjustment button is pressed, the motor starts to rotate the gas stove switch shaft to the place where the firepower is maximum, and the gas stove works in the fire mode. When the second firepower adjustment button is pressed, the motor starts to rotate the gas stove switch shaft to a place where the fire power is medium, and the gas stove works in the medium fire mode. When the third firepower adjustment button is pressed, the motor starts to rotate the gas stove switch shaft to the place where the firepower is the smallest, and the gas stove works in the low fire mode. In the prior art, the firepower is usually maximized when the gas stove switch button is rotated to the middle position. The second firepower adjustment button and the third firepower adjustment button also perform the adjustment of the firepower in the same manner.

It should be noted that after a certain firepower adjustment button 114 is pressed, the motor is energized, the motor drives the connecting member 101 to rotate by the transmission member 104, and the connecting member 101 drives the gas stove switch shaft 2 to rotate, thereby realizing the adjustment of the firepower. When the connecting member 101 is rotated to the preset position, the power supply circuit of the motor is turned off, and the motor stops outputting power. In this way, the firepower is maintained in the current state. As shown in FIG. 7, specifically, when the first thermal power adjustment button is pressed, when the connection hole position provided on the connection member 101 is rotated to the sensor 117 corresponding to the position of the large fire, the power supply circuit of the motor is turned off, and the motor stops rotating.

At this time, the first connecting member 1011 is mounted together with the OFF position positioning housing 4 and the gas stove switch button 1 and cannot be rotated relative to each other. The connecting member composed of the first connecting member 1011 and the second connecting member 1013 is a universal connecting member. It can be connected to various gas stove switch shafts 2. In the prior art, the gas stove switch shaft 2 is provided with different connection sections, and the angular relationship between the switching position of most of the gas stove switch shaft and the initial position of the OFF position positioning housing is 0 degree angle, 45 degree angle, and 8 angles such as 90 degree angle, 135 degree angle, 180 degree overlap, 225 degree angle, 270 degree angle, and 315 degree angle. At this time, the first connecting member 1011 can be matched with different gas cooker switch shaft cutting planes, and the first connecting member 1011 is rotatably fixed in the second connecting member 1013. For example, in a specific application scenario, the first connecting member 1011 can be disposed at a plurality of different positions relative to the second connecting member 1013. For example, when the gas stove switch shaft 2 is provided with a cutting plane of eight directions, the first connecting member The 1011 can be provided with eight different fixed positions relative to the second connecting member 1013 so that the first connecting member 1011 can be sleeved on the gas stove switch shaft 2. When the OFF position positioning housing 4 is in the initial position, the gas stove switch shaft 2 and the gas stove switch button 1 are both in the initial positions.

In order to solve the above technical problem, a plurality of protrusions may be disposed on the first connecting member 1011, and correspondingly, a plurality of grooves for accommodating the first connecting member 1011 may be disposed on the second connecting member 1013, and the first connecting member 1011 When rotating between the second connecting members 1013, it is possible to switch to different aspects to match the front of the gas stove switch shaft 2.

The connecting member 101 can be locked to the housing 102 by the locking member 103, so that the locking member 103 can be locked to lock the gas stove switch shaft 2, thereby ensuring the safety of use. In a specific application scenario, the hand cannot rotate the gas stove switch button 1. The fixing of the locking member 103 to the connecting member is completed by snapping or abutting.

Specifically, the locking member 103 can be provided as a screw with an inner corner head. In this way, a screwdriver or the like is required to rotate to complete the locking and opening, and the locking is reliable. When the gas stove firepower adjusting device 100 is built in the gas stove casing 3, the locking member 103 is disposed to pass through the elongated locking member 103 of the gas stove casing 3, and the end of the locking member is disposed in the gas stove Later, in this way, when the connector 101 is locked, the child or the like does not easily touch the locking member 103, thereby ensuring the safety of the gas stove.

Specifically, when the locking member 103 is engaged with the connecting member 101, a locking hole is provided in the connecting member 101, and the locking member 103 is snapped into the connecting member 101. It can be understood that, after the gas stove switch button 1 is turned on, the connecting member 101 is driven, and the aforementioned snap hole is dislocated, and the locking member 103 cannot lock the rotation of the switch shaft button 1 to ensure safety and prevent accidents.

Specifically, when the locking member 103 abuts against the connecting member 101, the locking member 103 contacts the connecting member 101, and the rotation of the connecting member 101 is blocked by frictional resistance. At this time, the locking member 103 may be a screw or the like.

Specifically, the locking member 103 can also be engaged with the elastic member. The locking member 103 is pressed to lock the connecting member 101, and the locking member 103 is pressed again to unlock. The elastic member at this time can apply a return spring. The lock member 103 is similar to a switch button (a manual reset switch, an automatic reset switch, etc.).
