Embodiment Construction
[0012] There are many specific implementation methods of the present invention, two of which are illustrated as examples. In the first method, the bag body of the constant temperature hot water bag of the present invention has a heat storage material in a sealed interlayer, such as image 3 . In the second method, the bag body of the constant temperature hot water bag of the present invention is filled with a plurality of independently sealed heat storage materials such as Figure 4 .

The invention discloses a constant-temperature hot water bag, and relates to a hot water bag, particular to a hot water bag which is constant in temperature in a period of time. After a common hot water bag is filled with boiling water just now, the hot water bag is very hot, and a human body cannot be in direct contact with the hot water bag and can even be scalded. The hot water bag can be in direct contact with the human body when the temperature is reduced after a period of time, and much heat energy is wasted during the period. The invention aims to solve the technical problem about provision of the constant-temperature hot water bag, more specifically, the hot water bag which is not very high in temperature and suitable for human body contact, and can keep a constant temperature for a period of time. According to a technical scheme, the constant-temperature hot water bag consists of a bag body and a heat storage material, and is characterized in that the heat storage material absorbs heat energy after a boiling liquid is poured into the hot water bag; the temperature of the hot water bag is reduced; after a period of time, the temperature of the liquid is lower than that of the heat storage material; the heat storage material releases the heat energy, so that the temperature of the hot water bag is kept in a designed range constantly for a period of time. The constant-temperature hot water bag can be widely applied to families, hospitals and the like, and is particularly suitable for children, the aged, pregnant women and the like.
Description
technical field [0001] The invention relates to a hot water bag, in particular to a hot water bag with constant temperature for a period of time. Background technique [0002] Ordinary hot water bags will be very hot after being filled with boiling water, and the human body cannot be directly touched, and even burns may occur. It takes a period of time for the temperature to drop before direct contact, during which the heat energy of the hot water bag is wasted a lot. From high temperature to cooling in ordinary hot water bags, the temperature decreases in equal proportion with time, such as figure 1 . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a constant temperature hot water bag, more specifically, to provide a hot water bag whose temperature is not too hot, suitable for human body contact, and can keep the temperature constant for a period of time. [0004] In order to solve the above problems, the tec...
