Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps, in particular to a swimming pool water pump. Background Art

[0002] At present, the existing filter pumps for swimming pools use a filter element composed of a filter layer and a filter cotton layer for filtering. The impurities generated by the filtration are driven by a motor and an ultrasonic generator to achieve the cleaning of the impurities. However, the service life of the filter cotton layer is short and it needs to be replaced regularly.

[0003] Reference is made to a Chinese utility model patent (authorization announcement number: CN214144916U) which discloses an environmentally friendly swimming pool circulating water pump, comprising a circulating water pump body, a base being fixedly connected to the bottom of the circulating water pump body, a filter shell being connected to the water pumping end of the circulating water pump body, a filter core being arranged inside the filter shell, the filter core comprising a filter mesh layer and a filter cotton layer from the inside to the outside, a fixed cover being sleeved on the outer surface of the filter core, a fixed cover being fixedly connected to the top ends of the filter core and the fixed cover, the fixed cover being located on the upper surface of the filter shell, a circulating water inlet pipe being connected to the side wall of the filter core being extended to the inside of the filter shell and being communicated with the side wall of the filter core, a motor and an ultrasonic generator being fixedly connected to the upper surface of the fixed cover, a driving end of the motor being extended to the inside of the filter core being fixedly connected to a rotating rod, a sewage outlet being provided at the bottom end of the filter core, a spiral push block being fixedly connected to one end of the rotating rod away from the motor, and an ultrasonic vibration head being fixedly connected to the inner side wall of the filter core.

[0004] The above-mentioned prior art can filter the water flow when the water flow is circulated through the arrangement of the filter element, the filter mesh layer, the filter cotton layer, and the circulating water inlet pipe, and retain the silt impurities inside the filter element to ensure the clarity of the circulating water flow, which is convenient for use in the swimming pool and at the same time avoids the influence of the silt impurities on the operation of the circulating water pump. The double-layer filtration also further improves the filtering effect. Through the arrangement of the ultrasonic generator, the ultrasonic vibration head, the sewage outlet, and the sewage pipe, the ultrasonic vibration head can clean up the impurities attached to the inner wall of the filter element and discharge them through the discharge outlet together with the filtered impurities. At the same time, through the arrangement of the motor, the rotating rod, and the spiral push block, the silt impurities can be pushed out to avoid excessive silt impurities clogging the sewage outlet.

[0005] In the above-mentioned prior art, impurities on the inner wall of the filter element are cleaned by an ultrasonic generator and an ultrasonic vibration head. However, due to the high cost required for ultrasonic technology, and the setting of a motor, a rotating rod, and a spiral push block, the silt impurities can be pushed out to prevent excessive silt impurities from clogging the sewage outlet. If the silt impurities are not cleaned for a long time, the silt will accumulate for too long and will be difficult to handle. Therefore, the above-mentioned shortcomings need to be improved urgently. Utility Model Content

A connecting rod 33 is provided on the outer peripheral wall of the sleeve 32, and a brush 34 for cleaning the inner wall of the collection chamber 50 is provided at the end of the connecting rod 33.

[0026] Furthermore, the brush 34 includes a brush plate 37, on which a connecting post 36 is provided. In the present application, the number of the connecting posts 36 is three, and they are evenly distributed on the outer peripheral wall of the sleeve 32. In addition to three, the connecting posts 36 can be any number. In the present application, three connecting posts 36 are used, which can make the connection between the connecting posts 36 and the brush plate 37 more stable. In addition, a sliding cavity 331 that slides with the connecting post 36 is provided in the connecting rod 33, and a spring 35 is provided between the sliding cavity 331 and the connecting post 36. The spring 35 always has a tendency to push the brush 34 to move closer to the inner wall of the collection chamber 50, so that the brush 34 is always in contact with the collection chamber 50. The brush 34 contacts the inner wall of the collecting chamber 50, and the connecting column 36 slides in the sliding cavity 331. Therefore, when the brush 34 encounters a large foreign object on the inner wall of the collecting chamber 50, it will not be stuck by the foreign object, but will avoid it by sliding the connecting column 36 on the brush plate 37 in the sliding cavity 331. The brush 34 can also clean the foreign object multiple times and then clean the foreign object from the inner wall of the collecting chamber 50 to the bottom of the collecting chamber 50.

The filter cartridge 5 is located in the filter chamber 22. The water outlet pipe 20 is connected to the water purification chamber 24. The filter plate 4 includes a top plate 41, a mounting frame 43 mounted on the top plate 41, and filter cotton 42 mounted in the mounting frame 43. Seals are provided between the mounting frame 43 and the top plate 41 and the box body 2. A handle 411 is provided on the top plate 41, so that it is more convenient to pull out the filter plate 4 for replacement.

[0030] During use: the water to be filtered is sucked into the collecting chamber 50 through the water inlet pipe 21, the water to be filtered is filtered for the first time through the filter screen 52, and the impurities on the inner wall of the collecting chamber 50 are cleaned after the motor 3 is started. When the water filtered once by the filter screen 52 enters the filter chamber 22, and the filter chamber 22 is filtered for the second time through the filter cotton 42, the water after the second filtration enters the clean water chamber 24, and the water after the second filtration is discharged through the water outlet pipe 20, thereby realizing the water filtration function.

[0031] In addition, when the filter plate 4 needs to be replaced, it can be replaced by manually lifting the filter plate 4 with the handle 411. When replacing the filter cartridge 5 or cleaning the impurities on the inner wall of the collecting chamber 50, the filter cartridge 5 is taken out of the filter chamber 22 by manually pulling the groove 511, and the impurities or garbage on the inner wall of the collecting chamber 50 are manually cleaned, thereby increasing the life of the filter cartridge 5 and achieving a better cleaning effect.
