Abstract

The invention discloses an electric hot-water bag with the pressure relief function. The electric hot-water bag is composed of a bag body, a heating element and a pressure relief element. The bag body, the heating element and the pressure relief element are fixedly connected in a sealed mode. The pressure relief element is composed of a pressure valve, an alarm, a pressure relief hole and a replaceable activated carbon cover. The longitudinal section of the pressure relief hole is trapezoidal, a large opening of the pressure relief hole stretches to the surface outside the bag body, a small opening of the pressure relief hole is formed inside the bag body, a fixed stop dog and an elastic blocking piece are located on the small opening, the fixed stop dog and the elastic blocking piece are fixedly connected with the pressure relief hole, the pressure valve is arranged between the fixed stop dog and the elastic blocking piece, the activated carbon cover is connected with the large opening of the pressure relief hole in a threaded sealing mode, the activated carbon cover is composed of a cover edge and an elastic cap, the alarm is arranged on the pressure valve, and when the pressure valve goes beyond the elastic blocking piece, an alarm can be given automatically.

Description

technical field [0001] The invention relates to an electric hot water bag. Background technique [0002] The electric hot water bag is heated by heating water, which is what we commonly call a hot water bag. Unlike the traditional hot water bag, the electric hot water bag saves the trouble of adding water. It only needs to be plugged in for 10 minutes to heat up. Because it can be recycled and the cost is low, it is loved by consumers. [0003] However, phenomena such as explosions frequently occur in hot water bags currently on the market, causing personal injury. The reason for this explosion phenomenon is mainly because the liquid water in the bag is heated, the water produces a large amount of water vapor, and the CO2 in the water is released. Although there is a space for water vapor in the existing hot water bag, it is difficult to grasp the vapor pressure, and there is no corresponding measure. Contents of the invention [0004] The technical problem to be solved...
