Hot water bag with functions of adjusting temperature and maintaining constant temperature

Abstract

The invention discloses a hot water bag with functions of adjusting temperature and maintaining constant temperature. The hot water bag comprises a hot water bag body, a water injection port is formedin one side of the hot water bag body, and rotatably connected with a cover body which is arranged at the portion, close to the water injection port, on the hot water bag body, and a temperature sensor is arranged inside the hot water bag body; the hot water bag body comprises a heat preservation inner layer and a heat preservation outer layer, the heat preservation inner layer and the heat preservation outer layer are made of silica gel materials, a heating device is arranged inside the hot water bag body, and is a heating wire which is subjected to water proofing treatment, and one side ofthe hot water bag body is provided with a power socket, a temperature display device and a temperature control device separately; the temperature value is set through the temperature control device, the heating device can then start to heat water, after the temperature reaches the predetermined value, heating is stopped, and the constant temperature is maintained. The hot water bag is simple in structure and convenient to operate. By means of the hot water bag, people do not need to worry about frigidity or coldness in the hands and feet, and the hot water bag is safer.

Description

technical field [0001] The invention relates to a daily necessities, in particular to a hot water bag which can regulate and maintain a constant temperature. Background technique [0002] In cold winter, many people like to use hot water bag to keep warm, because existing hot water bag can not keep warm like this because of water temperature drop sometimes, makes it cold on the contrary, makes people unable to fall asleep. Now the use of electric hot water bags is more and more widespread, and electric hot water bags bring convenience to people for heating. The hole plugs used for the vent holes of existing electric hot water bags are difficult to pull out after being plugged tightly, so that excess gas cannot be discharged in time, which affects the use. , and the hole plug is easily lost after being pulled out. Electric hot water bags are mostly made of heat-transfer rubber materials, which makes electric hot water bags easy to burn at high temperatures, and also shortens...

AI Technical Summary

Problems solved by technology

[0002] In the cold winter, many people like to use hot water bags to keep warm. Because the existing hot water bags sometimes drop due to the water temperature, they cannot keep warm, but make them cold and make people unable to sleep.

Now the use of electric hot water bags is more and more widespread, and electric hot water bags bring convenience to people for heating. The hole plugs used for the vent holes of existing electric hot water bags are difficult to pull out after being plugged tightly, so that excess gas cannot be discharged in time, which affects the use. , and the hole plug is easily lost after being pulled out

Electric hot water bags are mostly made of heat-transfer rubber materials, which makes electric hot water bags easy to burn at high temperatures, and also shortens the heat preservation time

And the heat preservation time of existing many electric hot water bags is not too long, when some electric hot water bags are not placed in quilt etc., its heat preservation time is shorter, thereby brings some inconvenience to people's use
