Detailed Description

An electric hot-water bag anti-dry heating body comprises a heating tube 7, and a slurry coating layer 8 is die-cast outside the heating tube 7. The slurry coating layer 8 is mainly wrapped outside the middle section of the electrothermal tube 7.

This application technical scheme is through addding package thick liquid layer 8 in the outside of heating tube 7, and this package thick liquid layer 8 adopts aluminium system material. The contact area between the heating tube 7 and the liquid in the electric hot water bag is increased, and the heating is quicker and more uniform when the temperature is raised.

The heating tube 7 is bent into a W-shaped structure. The structure prolongs the length of the heating tube 7 in a limited space, and the high temperature point 8-3 in the middle is arranged near the temperature controller mounting seat 8-1 at the edge while the heating is faster.

The slurry coating layer 8 is integrally provided with a temperature controller mounting seat 8-1.

The slurry coating layer 8 is provided with a plurality of flow guide holes 8-2 with two through surfaces. The flow guide holes 8-2 have the functions of facilitating the water flow in the hot water bag to pass through and adjusting the water temperature to be more balanced.

The temperature controller mounting seat 8-1 is arranged close to a high temperature point 8-3 in the middle of the pulp coating layer 8.

The structure enables the temperature controller 6 to be closer to a high temperature point 8-3, and under the condition of dry burning, the power supply can be conveniently and quickly cut off through the heat preservation switch 4, so that the protection effect is achieved. The whole product has good dry heating preventing effect, and even under the condition that the hot water bag is anhydrous, the heating tube 7 continuously heats for about 20 seconds to realize power failure.

And heat conducting ribs 8-4 connected to a temperature controller mounting seat 8-1 are arranged on two sides of a high temperature point 8-3 in the middle of the slurry coating layer 8. The heat conducting ribs 8-4 play a role in heat conduction, so that the high temperature of the high temperature point 8-3 can be conveniently and quickly transmitted to the temperature controller 6, and dry burning is avoided.

The thickness of the coating pulp layer 8 is 1.2-1.35 mm.

The outer part of the heating tube 7 is buckled with an outer cover shell consisting of an upper net cover 9 and a lower net cover 10.

The outer casing outside be provided with electrical apparatus package 5, install electrically conductive plug pin seat 3 in the electrical apparatus package 5, electrically connect to heating tube 7 on electrically conductive plug pin seat 3 still electricity is connected with temperature controller 6 and heat preservation switch 4, temperature controller 6 installs on temperature controller mount pad 8-1.

The outer side of the electric appliance bag 5 is fixed with a panel 2, and the panel 2 is rotatably connected with a sliding cover 1 for shielding the protective conductive pin seat 3.

The free ends of the two side pipe parts 7-2 of the heating pipe 7 are folded to form an angle towards the middle, and after the heating pipe 7 is folded into a W-shaped structure, the middle point 7-1 of the heating pipe does not exceed the middle point connecting line of the two side pipe parts 7-2. The heat pipe 7 is bent into a W-shaped structure, and the bent part adopts an arc-shaped structure for transition.

The wrapping length of the slurry coating layer 8 exceeds one half of the position of the two side pipe parts 7-2 of the heating pipe 7.

Wiring pins 7-3 extend from both ends of the heating tube 7.
