Description

Technical Field

[0001] The present invention relates to the technical field of swimming pool pumps, and more particularly to a speed-regulating swimming pool pump unit with a self-cleaning function. Background Art

[0002] In a swimming pool's water circulation system, the pool pump is a core component. Its efficient and stable operation is crucial for maintaining clean water quality and fluidity. Pool water inevitably contains various impurities, including but not limited to leaves, sand, hair, microorganisms, and human secretions. A pool pump generally consists of a motor, pump body, impeller, and filter. The motor drives the impeller inside the pump body to rotate, drawing pool water into the pump. The water is then transferred through pipes to the filter for filtration and treatment. Finally, the treated water is returned to the pool, completing the operation of the entire pool circulation system.

[0003] Existing pool pumps generally use filter cartridges as their primary filtration component, intercepting impurities through pores within the cartridge. As these cartridges perform their filtration tasks, impurities accumulate over time, resulting in a disordered distribution of impurities within the cartridge, gradually occupying a significant portion of the space originally intended for water flow and filtration. This means that impurities are scattered throughout the cartridge, unable to be centrally located and collected, leaving no additional filtration space. Even if some areas within the cartridge remain unobstructed, the scattered impurities prevent the filter from fully functioning, requiring frequent cleaning to maintain filtration effectiveness. Summary of the Invention

[0004] The present invention provides a speed-regulating swimming pool pump unit with a self-cleaning function, which solves the technical problem in the related art that impurities are randomly scattered in the filter cartridge and cannot be centrally collected.

A plug rod is installed at one end of the rotating shaft, and a through hole for the rotating shaft to pass through is opened on the filter cartridge.

[0008] As a further optimization solution of the present invention, a plurality of second filter holes are provided on both the first filter plate and the second filter plate.

DETAILED DESCRIPTION

[0027] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0028] according to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a speed-controlled swimming pool pump unit with a self-cleaning function includes a swimming pool pump body, which includes a motor 11. A pump housing 12 is mounted on the motor 11, and an impeller 13 is provided inside the pump housing 12. The output shaft of the motor 11 is fixedly connected to the impeller 13. When the motor 11 rotates, the impeller 13 is controlled to rotate synchronously, thereby facilitating the transmission of water flow in the swimming pool.

[0029] The pump housing 12 is mounted with a filter chamber 14, which houses a filter cartridge 15. The filter cartridge 15 is provided with a plurality of first filter holes 151 for intercepting impurities in the water. In this embodiment, the filter cartridge 15 and first filter holes 151 are configured to filter impurities in the swimming pool, thereby keeping the pool water clean and recyclable. The filter chamber 14 is equipped with a water inlet 17 and a transfer port 18, located within the pump housing 12. The pump housing 12 also includes a water outlet 19.

[0030] Specifically, a cover plate 16 is threadedly connected to the filter bin 14 for limiting the position of the filter cartridge 15. During operation, the threaded connection of the cover plate 16 facilitates quick disassembly and assembly of the filter cartridge 15, so that the filter cartridge 15 can be cleaned, thereby keeping the water in the swimming pool clean.

[0031] During operation, drive motor 11 is powered on, and its output shaft begins to rotate, driving impeller 13 to rotate at high speed along with the output shaft of motor 11. The high-speed rotation of impeller 13 within pump housing 12 generates centrifugal force. Simultaneously, pool water flows through water inlet 17 into filter chamber 14. Inside filter chamber 14, the water passes through filter cartridge 15, where it is filtered. Impurities in the water, such as leaves, sand, and hair, are trapped within filter cartridge 15, ensuring that the water entering subsequent components is relatively clean.

[0032] After being filtered by filter cartridge 15, water enters pump housing 12 through transfer port 18 on filter chamber 14. Here, the centrifugal force generated by the high-speed rotation of impeller 13 accelerates the water and flings it toward the edge of pump housing 12 before being discharged through outlet 19 mounted on the pump housing 12. Simultaneously, the water is continuously squeezed during its flow, increasing its pressure. The discharged water then flows back into the pool through the corresponding pipes, repeating this cycle continuously to filter and circulate the pool water, maintaining its cleanliness and fluidity.

[0033] In one embodiment, according to Figures 4 to 8 As shown, a self-cleaning component is provided inside the filter cartridge 15 for cleaning impurities inside the filter cartridge 15 .

[0034] Specifically, the self-cleaning component includes two upper and lower groups of connecting frames 21 arranged inside the filter cartridge 15, and the connecting frames 21 are connected by a guide plate 22. The interior of the filter cartridge 15 is provided with a limiting groove in an annular shape, and the limiting groove is slidably connected to the guide plate 22. The two groups of connecting frames 21 are also rotatably connected with a rotating shaft 23 through a bearing, and the rotating shaft 23 is provided with a first filter plate 24 and a second filter plate 25; the rotating shaft 23 and the first filter plate 24 are rotatably connected through a bearing, and the first filter plate 24 is fixedly connected to the connecting frame 21; the rotating shaft 23 and the second filter plate 25 are slidably connected, and an annular groove is provided inside the connecting frame 21, and a guide block is slidably connected in the annular groove, and the guide block is fixedly connected to the second filter plate 25; a number of second filter holes 26 are provided on the first filter plate 24 and the second filter plate 25. In this embodiment, the second filter plate 25 is driven to rotate by the rotating shaft 23, thereby collecting impurities between the first filter plate 24 and the second filter plate 25, leaving a filtration space within the filter cartridge 15. This extends the filtration time, avoids frequent replacement of the filter cartridge 15, and cleans the filter cartridge 15, thereby achieving a self-cleaning effect. In addition, the arrangement of the first filter plate 24 and the second filter plate 25 allows for a secondary filtration of impurities within the filter cartridge 15, thereby improving the filtration effect.

[0035] It should be noted that according to Figure 7As shown, a chute 231 is provided at the position where the rotating shaft 23 contacts the second filter plate 25, and a slider 232 is slidably connected to the interior of the chute 231. The slider 232 is fixedly connected to the second filter plate 25. A first spring 233 is provided inside the chute 231, and the two ends of the first spring 233 are respectively fixedly connected to the chute 231 and the slider 232. In this embodiment, when the rotating shaft 23 is rotated into place and there are too many impurities between the first filter plate 24 and the second filter plate 25, causing the filter to be unable to close, the slider 232 rotates within the chute 231, squeezing the first spring 233 and providing space for the second filter plate 25 to make way, thereby facilitating the pressure and gathering of impurities. The impurities inside the filter cartridge 15 are gathered and collected, freeing up excess filtering space for convenient filtration.

[0036] Among them, according to Figure 9 As shown, the end of the rotating shaft 23 away from the cover plate 16 passes through the connecting frame 21 and extends to the outer surface of the filter cartridge 15. A plug rod 27 is mounted on the end of the rotating shaft 23 away from the cover plate 16. The filter cartridge 15 has a through hole for the rotating shaft 23 to pass through. In this embodiment, the provision of the plug rod 27 facilitates connection with the pressure monitoring assembly and subsequent rotation of the second filter plate 25. The provision of the through hole facilitates assembly of the rotating shaft 23, allowing the entire self-cleaning assembly to be disassembled and easily installed.

[0037] In yet another embodiment, according to Figure 6 As shown, multiple groups of reeds 251 are installed on the second filter plate 25 , and a ball 252 is installed at one end of the multiple groups of reeds 251 away from the second filter plate 25 , and the ball 252 abuts against the inner wall of the filter cartridge 15 .

[0038] During operation, when the rotating shaft 23 drives the second filter plate 25 to rotate, the second filter plate 25 drives the reed 251 and the ball 252 to rotate synchronously inside the filter cartridge 15 , so that the ball 252 slides along the inner wall of the filter cartridge 15 .

[0039] The spheres 252 are positioned so as to align with each row of first filter holes 151. This means that as the spheres 252 rotate within the filter cartridge 15, the elastic force of the springs 251 continuously releases elastic force against the first filter holes 151. This constant contact causes micro-vibrations in the filter cartridge 15, allowing impurities clogged in the first filter holes 151 to be removed.

[0040] In one embodiment, according to Figure 2 、 Figures 8 to 10As shown, the pump housing 12 is provided with a pressure monitoring component for detecting the pressure inside the pump housing 12 , so as to facilitate the self-driving self-cleaning component to clean the inside of the filter cartridge 15 .

[0041] Specifically, the pressure monitoring assembly includes a connecting pipe 31 installed on the pump casing 12, and the connecting pipe 31 is communicated with the interior of the pump casing 12. The interior of the connecting pipe 31 is slidably connected to a guide rod 32, and a protrusion 33 is installed on the guide rod 32. A rack plate 35 is installed at the end of the guide rod 32 away from the protrusion 33, and a gear 36 is meshed with the rack plate 35. A connecting shaft is installed on the gear 36, and the connecting shaft is rotatably connected to the filter bin 14 through a bearing. A rotating disk 37 is also provided inside the filter bin 14, and the rotating disk 37 is fixedly connected to the connecting shaft. A square hole is opened inside the rotating disk 37, and the square hole is engaged with the insertion rod 27.

[0042] A second spring 34 is further provided on the outside of the guide rod 32 , and one end of the second spring 34 is fixedly connected to the guide rod 32 , and the other end of the second spring 34 is fixedly connected to the inner wall of the connecting tube 31 .

[0043] according to Figure 10 As shown, a sealing shell 38 is installed on the connecting tube 31, and a limiting column 381 is slidably connected to the interior of the sealing shell 38. One end of the limiting column 381 passes through the connecting tube 31 and extends to the interior of the connecting tube 31. A third spring 382 is provided on the limiting column 381, and both ends of the third spring 382 are fixedly connected to the limiting column 381 and the sealing shell 38, respectively.

[0044] Furthermore, an inclined surface 331 is formed on the outer edge of the projection 33, and the end of the limiting post 381 located inside the connecting tube 31 is inclined. In this embodiment, the inclined surface 331 and the limiting post 381 are inclinedly matched, so that the inclined surface 331 can squeeze the limiting post 381, so that the projection 33 and the limiting post 381 can be locked and fixed, thereby limiting the movement of the projection 33.

[0045] In addition, a pull ring is provided on the limit column 381. When the impurities inside the filter cartridge 15 are manually cleaned and the filter cartridge 15 is reassembled, the pull ring of the limit column 381 can be pulled to start the swimming pool pump body. When the internal pressure returns to normal, the pull can be released to reset the first filter plate 24 and the second filter plate 25.

[0046] It should be noted that during normal operation, the internal pressure of the pump housing 12 is high, and the internal water flow can squeeze the protrusion 33 inside the connecting pipe 31, so that the second spring 34 is in a compressed state, and the first filter plate 24 and the second filter plate 25 are in an extended state for a long time. Figure 5 and Figure 6 shown.

[0047] When there are too many impurities inside the filter cartridge 15, resulting in poor water flow, the water flow inside the pump housing 12 is in a low-pressure state, so that the protrusion 33 is reset under the action of the restoring force of the second spring 34, so that the inclined surface 331 squeezes the limit column 381, and the third spring 382 produces elastic deformation, thereby locking the protrusion 33.

[0048] When the protrusion 33 is reset under the action of the restoring force of the second spring 34, the rack plate 35 is driven to move. Through the meshing connection between the rack plate 35 and the gear 36, the rotating disk 37 is driven to rotate, thereby driving the rotating shaft 23 to rotate synchronously, so that the second filter plate 25 is rotated to gather and collect impurities.

[0049] The above describes an embodiment of this specific implementation method, but this embodiment is not limited to the above specific implementation method. The above specific implementation method is merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
