Problems solved by technology

However, once the thermostat fails and the electric hot water bag continues to heat, it will inevitably cause a large amount of water in the hot water bag to vaporize. Since the hot water bag is a sealed structure, the water cannot be released to the outside after vaporization, resulting in the increase of air pressure in the bag as the water temperature rises. When the pressure in the bag exceeds the capacity of the bag body, the air pressure can burst the hot water bag and cause an explosion
When this happens, the user is likely to be scalded by hot water and cause an accident.
[0003] Regarding the above-mentioned defects of electric hot water bags, I have designed several pressure-discharging explosion-proof electric hot water bags, but the common defect of these pressure-discharging explosion-proof electric hot water bags is that when the pressure is discharged, the water in the bag will be discharged together. The water inside may be charged when electrified, which creates a new unsafe factor

Embodiment Construction

[0016] Reference attached figure 1 An electric hot water bottle includes a bag body 1, a heating device, a temperature control device (not marked in the figure), an explosion-proof device 2, and a socket 3 in the bag body 1. The explosion-proof device 2 is installed in the center of the hot water bottle, and is glued to the bag body by thermal gluing, and the socket 3 is installed on the lower side of the explosion-proof device in the same way.

[0017] Reference attached figure 2 An explosion-proof device used on an electric hot water bottle includes a mounting seat 1, a locking sleeve 2, and a float 3.

[0018] The mounting seat 1 is made of plastic, with a hollow structure, a cylinder at the lower part, and a number of small meridional vents on the upper part of the cylinder; a larger outer circle in the middle part, the outer circle having a shorter axial dimension, and the upper end surface of the outer circle It is glued with the material of the bag body by heat, so that t...

Abstract

The invention relates to an explosion-protection electrical hot-water bag which comprises a bag body, a heater, a temperature controller, a plug, a water-storage device and an explosion-protection device. The explosion-protection device comprises a mount seat, a lock sleeve and a floating mark. By the arrangement of the explosion-protection device, the electrical hot-water bag thoroughly solves the problem that the conventional electrical hot-water bag can explode and hurt the user.

Description

1. Technical Field [0001] The invention relates to an explosion-proof electric hot water bottle. 2. Background technology [0002] The existing electric hot water bottle adopts electric heating, and the heating temperature is controlled by a temperature controller provided on the bag body. However, once the thermostat fails and the electric hot water bottle continues to heat up, it will inevitably cause a large amount of vaporization of the water in the hot water bag. Because the hot water bag is a sealed structure, the water cannot be discharged to the outside after vaporization, causing the air pressure in the bag to increase as the water temperature rises. Until the pressure in the bag exceeds the capacity of the bag body, the air pressure can burst the hot water bag and cause an explosion. When this happens, users are easily scalded by hot water and cause accidents. [0003] Regarding the above-mentioned shortcomings of electric hot water bottles, I have designed several pres...
