According to fig. 1-9:
a novel waterproof thermostat structure, includes:
the waterproof insulating shell 1 comprises a heat conducting surface limiting hole 11, an outer connecting hole 12 and a wire outlet hole 13, wherein the outer connecting hole 12 and the heat conducting surface limiting hole 11 are arranged at the left end of the wire outlet hole 13 from outside to inside, and the heat conducting surface limiting hole 11 comprises a heat conducting surface limiting ring 111 arranged at the bottom;

the wire assembly 3 comprises a wire contact head 31 and a wire terminal 32 arranged from left to right.
Since the wire contacts 31 are connected to the terminals 28 by soldering, the wire assembly 3 can be tightly connected to the terminals 28 by soldering.
Because the connection section of the moving contact induction piece 2621 and the moving contact bottom fixed piece 2622 is in a U shape and the two pieces are formed integrally, and the moving contact induction piece 2621 is driven by the action rod 23 through the induction point 2623, when a user uses the present invention, through the U-shaped arrangement, when the action rod 23 presses the induction point 2623 downwards, the moving contact induction piece 2621 bends downwards through the moving contact bottom fixed piece 2622 as a bottom plate, so that the moving contact 261 is contacted and separated with the fixed contact 253, thereby disconnecting the circuit of the present invention, when the induction point 2623 loses the pressing of the action rod 23, the moving contact induction piece 2621 resets upwards through the moving contact bottom fixed piece 2622 as a bottom plate, thereby the moving contact 261 is contacted with the fixed contact 253 again, thereby conducting the circuit of the present invention.
Because the fixed contact 253 and the movable contact 261 are inductive with each other, when a user uses the present invention, the circuit of the present invention can be contacted and disconnected by the contact or separation of the fixed contact 253 and the movable contact 261.
Because the heat-conducting cover ring pieces 211 are respectively limited by the heat-conducting surface limiting rings 111, and the outer diameter of the heat-conducting cover 21 is equal to the inner diameter of the heat-conducting surface limiting hole 11, when a user uses the heat-conducting cover ring piece limiting device, the upward movement of the heat-conducting cover ring pieces 211 can be limited through limiting, so that the parts arranged at the bottom of the heat-conducting cover 21 are also limited, the upward movement is prevented, and the normal use of the heat-conducting cover ring piece limiting device is influenced.
Because the outer diameter of the action rod 23 is equal to the inner diameter of the action rod movable hole 243, and the action rod 23 moves up and down in the action rod movable hole 243, when a user uses the circuit, the action rod 23 does not shake or deflect when moving up and down in the action rod movable hole 243 due to the equal diameters, so that the circuit can be normally opened, closed and contacted.
Since the outer diameters of the guide frame 24 and the housing 27 are respectively equal to the inner diameter of the heat conducting cover 21, and the outer diameter of the guide housing engaging ring 242 is equal to the inner diameter of the housing 27, when a user uses the present invention, the guide frame 24 and the housing 27 are respectively and firmly installed in the heat conducting cover 21 from top to bottom due to the equal diameters, and the phenomenon of position shaking does not occur in the heat conducting cover 21, thereby affecting the normal use of the present invention.
When the present invention is operated, the external temperature is transferred to the bimetal strip 22 through the heat conductive cover 21, when the externally sensed temperature is greater than the temperature set by the bimetal 22, the bimetal 22 moves downward, then the action rod 23 is pressed downwards, in real time, the action rod 23 can press the induction point 2623 at the end of the movable contact induction sheet 2621 downwards, in real time, the movable contact induction sheet 2621 moves downwards, thereby causing the movable contact 261 to be disconnected from the stationary contact 253, breaking the circuit, and when the external temperature is lowered to the reset temperature of the bimetal strip 22, when the bimetal strip 22 is reset upwards, the force for pressing the action rod 23 is lost, the real-time moving contact sensing strip 2621 will rebound upwards, thereby driving the moving contact 261 to move upward, so that the moving contact sensing piece 2621 and the sensing contact 2623 are contacted again, and the circuit of the present invention is closed again.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
