Referring to fig. 1 to 2, the device for solving the problem of the water diversion fault of the hot water pump in the utility model comprises a hot water pump 1, wherein the hot water pump 1 is connected with a sealed water storage container 3, the upper surface of the sealed water storage container 3 is connected with one end of a water suction pipe 2, and the other end of the water suction pipe 2 is a free end; when water needs to be pumped, the sealed water storage container 3 is kept in a full water state, the free end of the water suction pipe 2 is immersed in water, and then the hot water pump 1 is started to pump water.

Further, the longitudinal section of the barrel 2 is inverted L-shaped, the barrel 2 includes a longitudinal portion 21 parallel to the side of the sealed water storage container 3 and a lateral portion 22 parallel to the upper surface of the sealed water storage container 3, and the end of the lateral portion 22 is bent toward the sealed water storage container 3 and is sealingly connected to the sealed water storage container 3 by a flange 23. The transverse part 22 of the water suction pipe 2 is arranged above the sealed water storage container 3, so that water in the sealed water storage container 3 can not run off from the water suction pipe 2 and can be normally stored after the hot water pump 1 stops working. The flange 23 can detachably connect the sealed water storage container 3 and the water suction pipe 2, and when the water suction pipe 2 is soaked in water for a long time and rusts or is blocked, the flange can be detached for maintenance.

Furthermore, the free end of the longitudinal part 21 is connected with a filter cover 24, so that solid matters are prevented from entering the water suction pipe 2 to block the water suction pipe 2, and normal water diversion is influenced; more importantly, the hot water pump 1 is prevented from entering, and the hot water pump 1 is damaged.

Further, the upper surface of the sealed water storage container 3 is provided with a vent valve 34 and a water injection valve 32, wherein the vent valve 34 is adjacent to the flange 23, and the water injection valve 32 is connected with the water inlet pipe 31. When the water in the sealed water storage container 3 is too little or no water due to some inevitable factors, water can be added into the container through the water inlet pipe 31 and the water filling valve 32.

Further, a drain valve 33 is provided on the bottom side of the sealed water storage container 3. When the sealed water storage container 3 works for a long time, some impurities may be deposited in the container, and the water pump may be damaged and the valve may be blocked if the impurities are deposited more. The blowoff valve 33 can be opened periodically to clean the container, ensuring the cleanness in the container. After the cleaning is completed, water is injected into the water injection valve 32, and the sealed water storage container 3 is kept in a full water state.

Further, the hot water pump 1 is provided with two, and the requirement of different use scenes can be met.

Furthermore, a T-shaped suction pipe 122 is connected to the bottom side of the sealed water storage container 3, the T-shaped suction pipe 122 includes a longitudinal arm 122 and a cross arm 121 disposed in the middle of the longitudinal arm 122, and both ends of the cross arm 121 are respectively connected to the two hot water pumps 1 in a sealing manner through control valves 11.

Further, the sealed water storage container 3 has a cubic structure. The cube has a simple structure and a plurality of planes, and all parts connected with the sealed water storage container 3 can be connected on the container more easily, so that the construction difficulty is reduced.

The working principle of the embodiment is as follows: if the hot water pump 1 is not filled with liquid before starting, air exists in the pump, and the centrifugal force generated is small because the air density is small. The vacuum created at the suction port is not sufficient to draw liquid into the pump, and the hot water pump 1 is activated but is unable to deliver liquid. When water needs to be pumped, the sealed water storage container 3 is kept in a full water state, the free end of the water suction pipe 2 is immersed in water, and the hot water pump 1 is started to pump water. The full water condition can be achieved in two ways. Firstly, the ventilation valve 34 and the blow-down valve 33 are closed, water is filled into the water filling valve 32, and the state that the sealed water storage container 3 is full of water is kept; secondly, when the hot water pump 1 works, all parts of the whole device for solving the water diversion fault of the hot water pump are filled with water, and when the hot water pump 1 stops working, all water in the water suction pipe 2 falls back into the hot water pool due to the height difference; the transverse part 22 of the water suction pipe 2 is arranged above the sealed water storage container 3, so that water in the sealed water storage container 3 can not run off from the water suction pipe 2 and can be normally stored after the hot water pump 1 stops working.
