[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-4 As shown, a dustproof device for a silicone heating plate comprises a silicone heating plate body 1 and a connecting wire 2 arranged at a side position of the silicone heating plate body 1; a connecting slot column 3 is arranged at a side position of the connecting wire 2; a connecting sealing sleeve 5 is arranged at an outer side position of the connecting slot column 3, a telescopic inflatable cylinder 7 is arranged at a side position of the connecting sealing sleeve 5, a connecting internal thread column 8 is arranged at a middle position of the telescopic inflatable cylinder 7, the connecting internal thread column 8 is rotatably connected to the connecting sealing sleeve 5 through a thread, a toggle rotating knob 6 is arranged at a side position of the telescopic inflatable cylinder 7, the toggle rotating knob 6 is rotatably connected to the telescopic inflatable cylinder 7 through a rotating shaft, a built-in rubber airbag ring 9 is arranged at the inner side position of the connecting sealing sleeve near the right side, rotating the toggle rotating knob 6 can squeeze the telescopic inflatable cylinder 7 so that the inside of the built-in rubber airbag ring 9 is inflated to expand it, and the expanded built-in rubber airbag ring 9 can squeeze the plug-in fitting position for extrusion sealing, thereby effectively blocking dust from entering, thereby effectively improving the safety of the silicone heating plate.

[0024] like Figure 2 As shown, vertical lines are arranged on the outer side surface of the toggle rotating knob 6, and the toggle rotating knob 6 is connected to the telescopic inflator 7 via a rotating shaft. The vertical lines of the toggle rotating knob 6 can increase the friction between the toggle rotating knob 6 and the user's hand, thereby facilitating the rotating, squeezing and adjusting operation.

[0025] like Figure 2As shown, the connection slot column 3 is made of PVC material, and a metal contact piece is arranged at the inner side of the connection slot column 3. The metal contact piece of the connection slot column 3 can be connected to an external plug connector for power transmission.

[0026] like Figure 4 As shown, a dustproof coating 10 is provided at the outermost position of the silicone heating sheet 1. The dustproof coating 10 is made of polyurethane material. The dustproof coating 10 contains components such as polyol, isocyanate, catalyst and coupling agent. These components form polyurethane through chemical reaction, have good hydrophobic effect, and help prevent dust adhesion.

[0027] like Figure 4 As shown, an outer silicone layer 11 is arranged at the inner side of the dustproof coating 10, and the outer silicone layer 11 is made of silicone material. An inner glass fiber layer 12 is arranged at the inner side of the outer silicone layer 11, and the inner glass fiber layer 12 is wrapped by the outer silicone layer 11. A metal connection heating element 13 is arranged at the side of the inner glass fiber layer 12, and the metal connection heating element 13 is connected to the connecting wire 2 and heated by electricity. The outer silicone layer 11 is its external main structure. The outer silicone layer 11 is mainly responsible for providing insulation, heat conduction, wear resistance, flame retardancy and other functions. It can fill the gap of the contact surface and reduce the contact thermal resistance generated between the heat source surface and the contact surface of the heat dissipation device, thereby improving the heat transfer efficiency. In addition, the silicone layer can also withstand a certain pressure to ensure the close contact between the heating plate and the heated object, as well as the durability and safety in different environments. The built-in glass fiber layer 12 mainly plays a role in enhancing the tensile strength and voltage resistance of the product. Since the thinner silicone heating sheet has poor tensile strength and is prone to tearing during use, adding a built-in glass fiber layer 12 can improve its toughness and strength, enhance its functional effects such as high shear strength, puncture resistance and tear resistance, while not affecting the various thermal properties of the thermal conductive material itself. The metal-connected heating element 13 is used to generate heat after external power is applied.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
