Electric hot water bag

Abstract

The invention relates to an electric hot water bag. The electric hot water bag comprises a liner, a shell, an electric heating wire net and a socket, wherein the liner is used for filling liquid and is externally wrapped by the shell; the electric heating wire net is distributed in the liner; the socket is installed in the liner; the liner and the shell are formed through injection molding of soft materials; an air interlayer is formed between the liner and the shell; the liner and the shell are respectively formed by splicing upper and lower shells; the peripheries of the upper and lower shells of the liner are mutually spliced by adopting a welding process; the peripheries of the upper and lower shells of the shell are mutually spliced by adopting a welding process or an adhesive bonding process or a buckle connection process; a seal cover assembly corresponding to the position of the socket is arranged on the outer wall of the upper shell of the shell; and a plurality of fixing mechanisms used for fixing the electric heating wire net are arranged on the inner wall of the lower shell of the liner. The electric hot water bag has the characteristics of diverse preparation processes, low rejection rate, high product appearance plasticity, good sealing effects and high heating efficiency.

Description

technical field [0001] The invention relates to an electric hot water bag. Background technique [0002] With the improvement of people's living standards, electric hot water bags have become a must-have small household appliance, which can be used for heating, physical therapy and hot compress. Yet most electric hot water bags on the market still have the following defects: [0003] (1) Most of the electric hot water bags use PVC film as the water-holding shell, which is thin and easy to break, and has poor safety in use; [0004] (2) Since the electric hot water bag is made of laminated PVC film, the characteristics of PVC film doom it to be unable to make various three-dimensional shapes, the style is single, and the shape is rigid; [0005] (3) The shell of the electric hot water bottle adopts welding process, because the thickness of the PVC film is relatively thin, and it is easy to be welded through, so the requirements for welding technology are very high, and the ...

AI Technical Summary

Problems solved by technology

[0003] (1) Most of the electric hot water bags use PVC film as the water-holding shell, which is thin and easy to break, and has poor safety in use;

[0004] (2) Since the electric hot water bag is made of laminated PVC film, the characteristics of PVC film doom it to be unable to make various three-dimensional shapes, the style is single, and the shape is rigid;

[0005] (3) The shell of the electric hot water bottle adopts welding process, because the thickness of the PVC film is relatively thin, and it is easy to be welded through, so the requirements for welding technology are very high, and the scrap rate is also high;

[0006] (4) The shell of the electric hot water bag is made of PVC film, and the shape of the product is poorly shaped. Usually, the electric heating screen is used as the heating element. However, the position of the electric heating screen is not fixed, and it is easy to twist into a ball under the action of liquid or external force, so the inner tank The electric heating wire mesh in the bag is easy to break, and it is very easy to cause the accident that the bag body is scalded by the twisted electric heating wire mesh during the heating process
