Then the water filling valve is opened. Under the action of negative pressure suction, the water filling pipe pumps the water in the pool and pours it into the water diversion tank body, thereby realizing the automatic water filling function.

All other embodiments obtained by ordinary technicians in the field without creative work based on the embodiments of the utility model shall fall within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides an embodiment: an automatic water adding device for a centrifugal pump water tank, comprising a water tank body 1, a water level detection tube 2, a water adding pipe 3, and a centrifugal pump body 10. The water adding pipe 3 is arranged on one side of the water tank body 1, and a water adding valve 301 is installed at one end of the water adding pipe 3;

[0023] Specifically, by operating the controller 8 to open the water adding valve 301, under the action of negative pressure suction, the water adding pipe 3 draws water from the pool and pours it into the water diversion tank body 1, and the water diversion tank body 1 is automatically filled with water;

[0024] The water level detection tube 2 is fixed inside the water diversion tank body 1, and a stopper 11 is arranged inside the water level detection tube 2, and a float 12 is connected to the top of the stopper 11, a lower laser transmitter 13 and a lower laser receiver 17 are respectively installed on the two outer walls at the bottom of the water level detection tube 2, and an upper laser transmitter 14 and an upper laser receiver 15 are respectively installed on the two outer walls at the top of the water level detection tube 2;

[0025] Specifically, the water inside the water diversion tank body 1 is poured into the water level detection tube 2 through the through hole 16. Under the buoyancy of the water, the float 12 drives the block 11 to move up to the position of the upper laser transmitter 14 and the upper laser receiver 15. The block 11 blocks the laser beam emitted by the upper laser transmitter 14. If the upper laser receiver 15 cannot receive the laser signal, the signal is transmitted to the controller 8, indicating that the water is full. Then, the centrifugal pump body 10 is started to pump out the water inside the water diversion tank body 1 through the water outlet pipe 9. A negative pressure state is gradually formed inside the water diversion tank body 1. As the water level continues to move downward, the float 12 drives the block 11 to move downward. When the water level drops to a low level, the block 11 is located at the position of the lower laser transmitter 13 and the lower laser receiver 17. The block 11 blocks the laser beam emitted by the lower laser transmitter 13. If the lower laser receiver 17 cannot receive the laser signal, the signal is transmitted to the controller 8, indicating that the water level is low.

[0026] The top of the water tank body 1 is respectively provided with a water inlet pipe 6 and an air inlet pipe 7, and the connection between the water inlet pipe 6 and the air inlet pipe 7 and the water tank body 1 is respectively provided with a water inlet valve 601 and an air inlet valve 701;

[0027] Specifically, open the water inlet valve 601 and the air inlet valve 701, add water to the water tank body 1 through the water inlet pipe 6, and close the water inlet valve 601 and the air inlet valve 701 after the water is full.

[0028] The centrifugal pump body 10 is arranged on the other side of the water diversion tank body 1, and the input end of the centrifugal pump body 10 is connected with the water diversion tank body 1 through the water outlet pipe 9 on the outer wall of the water diversion tank body 1, and a controller 8 is installed on the outer wall of the water diversion tank body 1;

[0029] The outer surface of the water level detection tube 2 is provided with through holes 16 at equal intervals;

[0030] A filter box 4 is installed at the connection between the water supply pipe 3 and the water diversion tank body 1. The filter box 4 is connected to the water diversion tank body 1, and a filter screen 18 is installed inside the filter box 4.

[0031] Specifically, water enters the water diversion tank body 1 through the filter box 4, and the filter screen 18 filters the water to filter out the impurities inside the water diversion tank body 1, thereby preventing the impurities from being deposited in the water diversion tank body 1 and extending the service life of the centrifugal pump body 10;

[0032] A flushing pipe 20 is installed on the top of the filter box 4 on one side of the filter screen 18;

[0033] A water pump 5 is installed on one side of the top of the water diversion tank body 1, and the input end of the water pump 5 is connected to the water diversion tank body 1 through a water pumping pipe 502, and the output end of the water pump 5 is connected to the flushing pipe 20 through a water delivery pipe 501;

[0034] A sewage collecting pipe 19 is installed on one side of the bottom end of the filter box 4;

[0035] A sewage pipe 21 is installed at the bottom end of the sewage collecting pipe 19, and a sewage valve 22 is installed inside the sewage pipe 21;

[0036] Specifically, the water pump 5 is started to pump out the water inside the water tank body 1 through the water pumping pipe 502 and transport it to the flushing pipe 20 through the water delivery pipe 501. The flushing pipe 20 sprays water and flushes the filter 18, so that the impurities intercepted by the filter 18 are washed down, and the impurities and sewage are collected in the sewage collecting pipe 19. The sewage valve 22 is opened, so that the impurities and sewage in the sewage collecting pipe 19 are discharged to the outside through the sewage discharge pipe 21, thereby realizing the automatic cleaning function of the filter 18;

[0037] The lower laser transmitter 13 , the lower laser receiver 17 , the upper laser transmitter 14 , and the upper laser receiver 15 are all sealed in a waterproof cover, and the lower laser transmitter 13 cooperates with the lower laser receiver 17 , and the upper laser transmitter 14 cooperates with the upper laser receiver 15 .

[0038] When the embodiment of the present application is used: first, the water adding pipe 3 is extended into the pool, and then the water inlet valve 601 and the air inlet valve 701 are opened, and water is added to the water diversion tank body 1 through the water inlet pipe 6. After the water is filled, the water inlet valve 601 and the air inlet valve 701 are closed. At this time, the water inside the water diversion tank body 1 is poured into the water level detection tube 2 through the through hole 16. Under the buoyancy of the water, the float 12 drives the stopper 11 to move up to the position of the upper laser transmitter 14 and the upper laser receiver 15, and the stopper 11 transmits the laser emitted by the upper laser transmitter 14 to the water level detection tube 2. When the laser beam is blocked and the upper laser receiver 15 cannot receive the laser signal, the signal is transmitted to the controller 8, indicating that the water is full. Then, the centrifugal pump body 10 is started to pump the water inside the water tank body 1 through the water outlet pipe 9. A negative pressure state is gradually formed inside the water tank body 1. As the water level continues to move downward, the float 12 drives the block 11 to move downward. When the water level drops to a low level, the block 11 is located at the position of the lower laser transmitter 13 and the lower laser receiver 17. The block 11 blocks the laser beam emitted by the lower laser transmitter 13. If the lower laser receiver 17 does not receive the laser signal, it transmits the signal to the controller 8, indicating that the water level is low. At this time, the water filling valve 301 is opened by operating the controller 8. Under the action of negative pressure suction, the water filling pipe 3 draws water from the pool and pours it into the water tank body 1, and the water tank body 1 is automatically filled with water. In this process, water passes through the filter box 4 and enters the water tank body 1. The filter 18 filters the water and filters out the impurities inside it, thereby preventing the impurities from being deposited in the water tank body 1 and prolonging the centrifugal force. The service life of the pump body 10 is extended. After a period of use, the water pump 5 is started to pump out the water inside the water tank body 1 through the pumping pipe 502 and transport it to the flushing pipe 20 through the water delivery pipe 501. The flushing pipe 20 sprays water and flushes the filter 18, so that the impurities intercepted by the filter 18 are washed down, and the impurities and sewage are collected in the sewage collecting pipe 19. The sewage valve 22 is opened to discharge the impurities and sewage in the sewage collecting pipe 19 to the outside through the sewage pipe 21, thereby realizing the automatic cleaning function of the filter 18.
