Description

Technical Field

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

[0002] In a pool water circulation system, the pool pump is a core component of the water circulation system. Its efficient and stable operation is crucial for maintaining the cleanliness of the pool water quality and the fluidity of the water body. Inevitably, various impurities will be mixed into the pool water, including but not limited to leaves, sand, hair, microorganisms, and human secretions, etc. Among them, the pool pump generally consists of a motor, a pump body, an impeller, a filter, etc. The motor drives the impeller in the pump body to rotate, sucks the pool water into the pump, then transmits it through a pipeline to the filter for filtration and treatment, and finally sends the treated water back into the pool to complete the operation of the entire pool circulation system.

[0003] Existing pool pumps generally use a filter cartridge as the main filtering component, and intercept impurities through the filter holes opened on the filter cartridge. When the existing filter cartridge performs the filtering task, as the use time increases, impurities will continuously accumulate inside the filter cartridge, resulting in the impurities being disorderly distributed inside the filter cartridge, gradually occupying a large amount of the space originally used for water flow through and filtration. That is to say, the impurities are randomly scattered inside the filter cartridge and cannot be centrally placed, so no extra filtering space can be vacated. Even if there are still some areas in the filter cartridge that are not completely blocked, due to the dispersion of the impurities, the filtering effect cannot be fully exerted, so that the staff needs to clean the filter cartridge frequently to maintain the filtering effect. Summary of the Invention

DETAILED DESCRIPTION

[0027] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative 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-regulating swimming pool pump unit with self-cleaning function includes a swimming pool pump body, the swimming pool pump body includes a motor 11, a pump housing 12 is mounted on the motor 11, and an impeller 13 is arranged inside the pump housing 12, and an 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, so as to facilitate the transmission of water flow in the swimming pool.

[0029] The pump housing 12 is provided with a filter chamber 14, and a filter cartridge 15 is provided inside the filter chamber 14; wherein, 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 the first filter holes 151 are provided for filtering impurities in the swimming pool, so that the water in the swimming pool can be kept clean for recycling. The filter chamber 14 is provided with a water inlet 17 and a transmission port 18, and the transmission port 18 is located inside the pump housing 12. The pump housing 12 is also provided with 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, the drive motor 11 is powered on and starts to rotate, and its output shaft begins to rotate to control the impeller 13 to rotate at a high speed along with the output shaft of the motor 11. The high-speed rotation of the impeller 13 inside the pump housing 12 generates centrifugal force. At the same time, the water in the swimming pool flows into the filter chamber 14 through the water inlet 17. Inside the filter chamber 14, the water flow passes through the filtration of the filter cartridge 15, and impurities in the water, such as leaves, sand, hair, etc., are intercepted inside the filter cartridge 15, thus ensuring that the water entering the subsequent components is relatively clean.

[0032] The water filtered by the filter cartridge 15 enters the inside of the pump housing 12 through the transfer port 18 on the filter chamber 14. At this time, under the action of the centrifugal force generated by the high-speed rotation of the impeller 13, the water is accelerated and thrown towards the edge of the pump housing 12, and then discharged from the water outlet 19 installed on the pump housing 12. At the same time, the water flow is continuously squeezed during the flowing process, thereby realizing the pressurization of the water. The discharged water flow then flows back into the swimming pool through the corresponding pipeline, and so on in a cycle, realizing the continuous filtration and circulation of the swimming pool water to maintain the cleanliness and fluidity of the swimming pool water.

[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 the impurities inside the filter cartridge 15.

[0034] Specifically, the self-cleaning component includes two sets of connecting frames 21 arranged up and down inside the filter cartridge 15, and the connecting frames 21 are connected by a guide plate 22. An annular limiting groove is formed inside the filter cartridge 15, and the limiting groove is slidably connected with the guide plate 22. A rotating shaft 23 is rotatably connected between the two sets of connecting frames 21 through a bearing, and a first filter plate 24 and a second filter plate 25 are provided on the rotating shaft 23; the rotating shaft 23 is rotatably connected with the first filter plate 24 through a bearing, and the first filter plate 24 is fixedly connected with the connecting frame 21; the rotating shaft 23 is slidably connected with the second filter plate 25. An annular groove is provided inside the connecting frame 21, and a guide block is slidably connected inside the annular groove, and the guide block is fixedly connected with the second filter plate 25; a plurality of second filter holes 26 are formed on both 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, which is convenient for gathering and collecting the impurities between the first filter plate 24 and the second filter plate 25, leaving the filtering space inside the filter cartridge 15, so as to extend the filtering time, avoid frequent replacement of the filter cartridge 15, and clean the filter cartridge 15, thereby achieving the self-cleaning effect. In addition, through the arrangement of the first filter plate 24 and the second filter plate 25, the impurities inside the filter cartridge 15 can be secondarily filtered to improve the filtering 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 inside the chute 231, and 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 in place, and there are too many impurities between the first filter plate 24 and the second filter plate 25 so that they cannot be closed, the slider 232 and the chute 231 are rotated to squeeze the first spring 233, and provide a space for the second filter plate 25 to make way, so as to facilitate the pressure and gathering of impurities, gather and collect impurities inside the filter cartridge 15, and free up excess filtering space for convenient filtering.

[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. The end of the rotating shaft 23 away from the cover plate 16 is installed with a plug rod 27, and the filter cartridge 15 is provided with a through hole for the rotating shaft 23 to pass through. In this embodiment, the provision of the plug rod 27 facilitates splicing with the pressure monitoring component and facilitates the subsequent driving and rotation of the second filter plate 25; the provision of the through hole facilitates the assembly of the rotating shaft 23, so that the entire self-cleaning component can be dismantled and installed conveniently.

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

[0039] The sphere 252 is arranged in an orientation aligned with each row of the first filter holes 151. That is, when the sphere 252 rotates inside the filter cartridge 15, under the elastic action of the reed 251, the sphere 252 continuously releases elastic force to the inside of the first filter holes 151, and in the continuous contact process, the filter cartridge 15 is micro-vibrated, so that the impurities blocked in the first filter holes 151 can be removed.

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

[0041] Specifically, the pressure monitoring component includes a connecting pipe 31 installed on the pump housing 12, and the connecting pipe 31 is in communication with the inside of the pump housing 12. A guide rod 32 is slidably connected inside the connecting pipe 31, and a convex block 33 is installed on the guide rod 32. One end of the guide rod 32 away from the convex block 33 is installed with a rack plate 35, 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 chamber 14 through a bearing. A rotating disk 37 is further provided inside the filter chamber 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] Wherein, a second spring 34 is further provided outside 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 pipe 31.

[0043] According to Figure 10 As shown, a sealing housing 38 is installed on the connecting pipe 31, and a limiting column 381 is slidably connected inside the sealing housing 38. One end of the limiting column 381 passes through the connecting pipe 31 and extends into the inside of the connecting pipe 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 housing 38 respectively.

[0044] Furthermore, an inclined surface 331 is provided on the outer edge of the convex block 33, and one end of the limiting column 381 located inside the connecting pipe 31 is inclined. In this embodiment, through the inclined cooperation of the inclined surface 331 and the limiting column 381, it is convenient for the inclined surface 331 to extrude the limiting column 381, so that the convex block 33 and the limiting column 381 can be engaged and fixed to limit the movement of the convex block 33.

[0045] In addition, a pull ring is provided on the limiting column 381. When manually cleaning the impurities inside the filter cartridge 15 and re-assembling the filter cartridge 15, the pull ring of the limiting column 381 can be pulled, and the main body of the pool pump is started. When the internal pressure returns to normal, the pulling is released, and the first filter plate 24 and the second filter plate 25 can be reset.

[0046] It should be noted that during normal operation, the pressure inside the pump casing 12 is relatively high, and the internal water flow can squeeze the convex block 33 inside the connecting pipe 31, causing the second spring 34 to be in a compressed state, so that the first filter plate 24 and the second filter plate 25 are in an unfolded state for a long time. According to 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 casing 12 is in a low-pressure state at this time. As a result, the convex block 33 is reset under the action of the restoring force of the second spring 34, so that the inclined surface 331 squeezes the limit post 381, and the third spring 382 generates elastic deformation, thereby locking the convex block 33.

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

[0049] The above describes the embodiments of the specific implementation manner, but this embodiment is not limited to the above specific implementation manner. The above specific implementation manner is only illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
