Processing method of electrical heated tube type electric thermal bag

Abstract

A processing method of an electrical heated tube type electric thermal bag is disclosed. The electrical heated tube type electric thermal bag comprises an electrical heating assembly installed in the bag and a socket assembly connected between the electrical heating assembly and the bag body. An electrical appliance controller is arranged in the socket assembly. The bag body comprises an outer layer and an inner layer. A hot pressing edge is arranged at the edge of the bag body. The bag body is provided with a socket aperture and a watering exhaust hole. The socket assembly comprises a socketcover connected with the socket. A plug bush and a spiral cover are connected externally with the socket. The electrical heating assembly comprises an electrical heated tube and a leading wire. A protective bracket is installed outside the electrical heated tube. The processing method comprises the steps of: (1), manufacturing the electrical heating assembly; (2), molding a high temperature resisting insulating layer; (3), molding a PVC (Polyvinyl Chloride) connecting cover; (4), molding the socket cover; (5), welding the electrical heating assembly and the socket cover; (6), installing a temperature controller; (7), installing the socket assembly; (8), installing the protective bracket of the electrical heated tube; (9), preparing materials for the bag body; (10), punching the bag body; (11), welding the bag body; (12), testing pressure and detecting leakage; (13), adding a heat storage liquid; (14), testing electricity; and (15) packaging and putting in storage.

Description

technical field [0001] The invention relates to an electric heating bag (or called an electric hot water bag), in particular to a processing method of an electric heating tube type electric heating bag. Background technique [0002] The traditional warm water bag (or hot water bag) is made of rubber material, filled with hot water, and has the characteristics of simple structure and low cost. But its disadvantage is that it is easy to cool down, and it is troublesome to pour hot water. Now the amount is gradually reduced. Therefore, an electric heating bag (or electric hot water bag) has been developed. The bag body of the electric hot water bag is generally made of two layers of material, cloth and plastic. In the bag body, heating liquid is filled, and an electric heating device is installed. Heating, once it cools down, it can be reheated, it is more convenient to use, and the time can be controlled by yourself. Most of the heating devices of the existing electric heati...

Problems solved by technology

Most of the heating devices of existing electric heating bags are electrode-type heating, and the electrode cover has a protective bracket, but because there are still many potential safety hazards, the state has issued an explicit order to prohibit production
