The structure of the bimetallic strip 606 can be a combination of copper and steel, and the upper surface is copper and the lower surface is steel. When the temperature rises, due to the difference in thermal expansion coefficients of the two metals, the metal strip will bulge upward, that is, the copper surface will bend upward, and by setting the temperature sensing block 605, the heating area of ​​the bimetallic strip 606 can be increased, which can ensure that the bimetallic strip 606 obtains heat more quickly and evenly, thereby improving the heating efficiency of the bimetallic strip 606.

The rotation speed of the fan 3 increases the air flow in the box 1 and accelerates the heat dissipation. The fifth tooth plate 610 is slidably installed in the inner cavity of the box 1. The push plate 608 is fixedly connected to the bottom of the fifth tooth plate 610. The seventh gear 611 is fixedly installed at one end of the third shaft 603.

When the bimetallic strip 606 is heated and bulges upward, it can synchronously drive the fifth gear plate 610 to move upward, thereby driving the seventh gear 611 and the grille 602 to rotate counterclockwise, increasing the opening of the heat dissipation hole and accelerating heat dissipation.

[0049] Specifically, the working principle of the composite material box structure is as follows: when in use, the box 1 can be cooled in real time by the cooling fan 3, and the electric telescopic rod 408 can be operated at a fixed time by an external timer, thereby driving the first tooth plate 407 to move, thereby driving the first gear 406 to drive the mounting plate 402 to rotate 180 degrees, so that the two filter plates 404 are alternately connected to the ventilation holes 405 to filter the dust in the air, and when the mounting plate 402 rotates, the second gear 411 can be driven to rotate synchronously by the gear ring 409, and the second gear 411 can be driven to rotate synchronously by the gear ring 409. The third gear 412 drives the fourth gear 413 and the cleaning disk 414 to rotate, and cleans the dust on the surface of the filter plate 404 through the brush 415, which is convenient for use. At the same time, when the mounting disk 402 rotates, the arc block 422 contacts the arc groove surface of the driving block 423, and the driving block 423 drives the arc block 422 to move downward, driving the third tooth plate 421 to move downward synchronously, and drives the second tooth plate 419 and the filter plate 404 to move upward through the fifth gear 420, so that the brush 415 is close to the side wall of the filter plate 404, thereby improving the cleaning effect.

[0050] The insect-proof cover 501 can block insects from entering the inner cavity of the box body 1, preventing the risks of insects causing electrical short circuits, and when the electric telescopic rod 408 drives the mounting plate 402 to rotate, the first pulley 507 and the bidirectional screw rod 506 can be driven to rotate synchronously through the second pulley 508, so that the cleaning rollers 504 on both sides are driven to move closer to or away from each other through the threaded block 505, so as to clean the insects accumulated on the surface of the insect-proof cover 501 and ensure the ventilation effect, and the cleaning rollers 504 can be driven to rotate synchronously through the fourth tooth plate 509 to improve the cleaning efficiency.

[0051] When the temperature in the box 1 rises, the bimetallic strip 606 bulges upward due to the heat, thereby driving the connecting rod 607 and the push plate 608 to move upward, pushing the telescopic end of the speed control switch 609 to move upward, thereby increasing the rotation speed of the cooling fan 3 and improving the air flow in the box 1. When the bimetallic strip 606 bulges upward due to the heat, it can synchronously drive the fifth gear plate 610 to move upward, thereby driving the seventh gear 611 and the grille 602 to rotate counterclockwise, increasing the opening of the heat dissipation hole and accelerating heat dissipation.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
