[0046] The following embodiments illustrate the present invention, but the present invention is not limited by these embodiments. Modifying the specific embodiments of the present invention or equivalently replacing some technical features without departing from the spirit of the present invention's solution shall all be covered within the scope of the technical solution claimed by the present invention.

[0047] Please refer to Figures 1-6, the present invention provides a stove detection device, including a frame 3 and an airtightness detection structure 100 installed on the frame 3. The airtightness detection structure 100 includes an airtightness detection station, a solenoid valve wiring structure, and a gas connection structure. The airtightness detection station is arranged on the frame 3 and is used to place the stove 2 to be detected. The solenoid valve wiring structure is installed on the frame 3, can be connected to the solenoid valve of the stove 2, and can control the on-off of the solenoid valve of the stove 2. The gas connection structure is installed on the frame 3, can be connected to the air passage of the stove 2, and is used to supply gas to the stove 2. Specifically, when detecting the airtightness of the stove 2, connect the inlet pipe of the stove 2 to the gas connection structure so that the gas connection structure can supply gas to the stove 2. Then, control the solenoid valve of the stove 2 to be powered on through the solenoid valve wiring structure, so that the solenoid valve is in the open state, and then perform the airtightness detection. Then, control the solenoid valve of the stove 2 to be powered off through the solenoid valve wiring structure, and then turn the knob 23 of the stove 2 (the knob 23 rotates counterclockwise by 90 degrees), so that the valve stem of the solenoid valve of the stove 2 is opened (at this time the solenoid valve is in the closed state), and perform the airtightness detection again, so as to realize the airtightness detection of the solenoid valve when it is opened and closed. After the test is completed, turn the knob 23 of the stove 2 to reset the knob 23, which solves the problem that in the prior art, only by unplugging and plugging the solenoid valve connection wire can the airtightness detection of the solenoid valve be realized when it is opened and closed, thereby improving the detection efficiency.

[0048] Specifically, the solenoid valve wiring structure is connected to the solenoid valve of the stove 2 by plugging into the solenoid valve interface 21 of the stove 2.

When the power-on pulley 15 moves relative to the power-on part 16 to the second position, the power-on part 16 is disconnected from the power supply structure. By controlling the position of the power-on pulley 15 moving relative to the power-on part 16, the on-off between the power-on part 16 and the power supply structure can be controlled, thereby realizing the quick connection and disconnection between the power-on part 16 and the power supply structure and improving the test efficiency.

Specifically, when the trachea docking device 111 is pressed downward so that the trachea docking device 111 is inserted into the ventilation portion 112, the trachea docking device 111 is connected to the ventilation portion 112 and the ventilation portion 112 is opened. At this time, the trachea docking device 111, the ventilation portion 112, and the ventilation pipe 12 are connected; when the docking device is pulled upward, the trachea docking device 111 resets and disengages from the ventilation portion 112, and thus is disconnected from the ventilation portion 112, and the ventilation portion 112 is closed. At this time, the trachea docking device 111, the ventilation portion 112, and the ventilation pipe 12 are disconnected.

The second end of the support rod 152 can always be higher than the first end of the support rod 152 under the elastic force of the elastic member 154, so that the pulley body 153 provided at the second end of the support rod 152 contacts the energized portion 16, thereby conducting the energized portion 16 and the power supply structure. When it is necessary to disconnect the connection between the energized portion 16 and the power supply structure, the upper end of the second support rod 152 is pressed down to overcome the elastic force of the elastic member 154, so that the pulley body 153 is disengaged from the energized portion 16, and the disconnection between the energized portion 16 and the power supply structure can be achieved.
