AI Technical Summary

Technical Problem

On the market, electric toothbrushes with metal shells have great risks due to easy separation between injection molded parts and hardware shells, poor waterproof airtightness, and failure of product structure.

Method used

The hardware outer shell is used to fixedly connect the hardware structural parts by welding, and the hardware structural parts are arranged in an annular cross-section on the hardware structural parts, which is closely attached to the inner wall of the hardware outer shell, and the fixed connection is achieved through a traceless welding process, replacing the traditional nano-injection molded structural parts.

Benefits of technology

It effectively reduces the overall cost of the product, solves the heat problem caused by post-process processing of traditional nano-injection molded structural parts, avoids the separation of plastic parts and hardware parts and poor airtightness, and avoids the risk of product failure caused by plastic aging.

Abstract

The utility model discloses a hardware shell structure of an electric toothbrush, which comprises a hardware outer shell which is of a cylindrical structure, a mounting cavity is formed in the hardware outer shell, and a hardware structural member is arranged in the mounting cavity; the hardware structural part is fixedly connected with the hardware outer shell in the mounting cavity in a welding machining mode. The hardware structural part arranged by adopting a traceless butt-welding process with lower processing cost is adopted to replace a traditional structural part formed by nano injection molding, so that the overall product cost can be effectively reduced, and the problems that a plastic part and the hardware part are separated due to heat generated by processing procedures such as subsequent processing and polishing of the traditional nano injection molding structural part, and the product quality is influenced are solved. And meanwhile, the technical problem of product failure caused by plastic aging is avoided.
