The working principle of the hot water bag is as follows: when the heater is not connected to the hot-water bag body 1, the first water inlet 20a is in a closed state under the action of the first elastic member 4a by the first valve rod 3a of the first water inlet channel 22 in the hot-water bag body 1, and the first water inlet 20b is in a closed state under the action of the second elastic member 4b by the second valve rod 3b in the first water outlet channel 23; only when the plug 7 on the heater is inserted into the interface 2 on the hot water bag body 1, the first push rod 10a in the second water inlet channel 71 abuts against the first valve rod 3a in the first water inlet channel 22, so that the first water inlet 20a is communicated with the second water inlet 70a, similarly, the second push rod 10b in the second water outlet channel 72 abuts against the second valve rod 3 in the second water inlet channel 23 when the second valve rod 3 is started, so that the first water outlet 20b is communicated with the second water outlet 70b, the water pump 8 can be started, water in the hot water bag is pumped into the heating device 9 for heating, and water flow heated by the heating device 9 returns to the hot water bag, so that the hot water bag is filled with hot water.
In the invention, the interface with the first water stop valve is arranged on the hot water bag body, so that the water in the hot water bag body can be prevented from flowing outwards, and in addition, the water can be circulated only by the heater matched with the hot water bag, so that the hot water bag is filled with hot water, the hot water bag does not need to be heated in the hot water bag body, and the bag explosion phenomenon caused by heating in the hot water bag body is avoided; in addition, the hot water bag and the heater are split, so that the hot water bag and the heater are not influenced mutually, only a failed product needs to be replaced once one of the heater or the hot water bag fails, meanwhile, the heater is strong in universality, a plurality of hot water bags can be heated, and the heater is easy to detach and maintain after the heater fails.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
