Heating closestool cover plate and preparation process thereof

Abstract

The invention provides a heating closestool cover plate. The heating closestool cover plate comprises a seat ring and a heating wire in the seat ring. The seat ring comprises a first ring body and a second ring body. The heating wire is located between the first ring body and the second ring body and is embedded in the first ring body. The two ends of the heating wire are connected with positioning copper points. Positioning holes corresponding to the positioning copper points in position are formed in the first ring body. The positioning copper points fall into the positioning holes. The second ring body is formed on the surface where the first ring body is embedded with a heating wire to form a solid seat ring. The invention further provides a preparation process of the heating closestool cover plate. The heating wire is implanted in the seat ring, the heat conduction speed is high and stable, the product is attractive, light and thin, and the heating cost is low.

Description

technical field [0001] The invention relates to a heating toilet cover and a preparation process thereof. Background technique [0002] see Figure 1-4 The conventional heating toilet cover usually uses aluminum foil 11 as a heat transfer carrier, and the heating wire 12 is bonded to the aluminum foil 11 through an auxiliary adhesive to form a sheet heater. The back of the aluminum foil uses high-temperature resistant double-sided adhesive 13 directly After sticking to the inside of the seat ring 10, cover the bottom cover 14 to seal, such as figure 1 As shown, the seat ring 10 and the bottom cover 14 are made of plastics such as PP and ABS, and the seat ring 10 fuses the bottom cover 14 together by hot melting to form a sealed space. Since the parts are made of ordinary plastics, the products often have deformation and shrinkage, resulting in misalignment of the products after welding, edging or large gaps. Therefore, the seat ring 10 is often larger than the bottom cove...

AI Technical Summary

Problems solved by technology

Since the parts are made of ordinary plastic, the product often has deformation and shrinkage, which leads to dislocation, shattering or large gaps after welding.

Therefore, the seat ring 10 is often larger than the bottom cover 14 when designing, so that the misalignment of the product after welding is not obvious, but steps 15 will be generated, which will affect the appearance of the product, such as Figure 4 shown

In addition, due to structural limitations, the product needs to be assembled by overlapping and welding multiple parts. The product has a thick shape and cumbersome assembly.
