[0002] The thermostat clip detection device is a supporting device for thermostat detection. The thermostat refers to a temperature-controlled switch that produces certain special effects by physically deforming the temperature sensing element inside the switch according to the temperature changes in the working environment.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a temperature controller clip detection device based on magnetic flux, which has the following beneficial effects: the temperature controller clip detection device based on magnetic flux uses a cylinder to press down the metal cover of the thermostat from the top, and then uses another cylinder to lower and raise the small magnet inside, causing the floating of the temperature sensing element inside the thermostat, and judges whether there is a clip phenomenon by detecting the change of magnetic flux.

The clamping plate is positioned to press the position of the thermostat element for positioning. After positioning, the driving cylinder is started to drive the connecting shaft and drive the position of the magnet to vibrate up and down, driving the middle rod-shaped mechanism to move up and down. The bottom is equipped with a magnet and reaches the middle position of the upper part of the metal cover. The magnetism of the magnet is used to make the temperature sensing piece in the metal cover float up and down, thereby generating a change in the magnetic flux. If the magnetic flux does not change, the instrument pointer is near 0, and it is determined that the thermostat has a defective clip. If the magnetic flux changes, the instrument pointer deflects to the right and then returns, which can be determined as no defective clip. The entire thermostat clip detection device has a simple structure, is easy to operate, and has a better effect than the traditional method. BRIEF DESCRIPTION OF THE DRAWINGS
