Description

Technical Field

[0001] The present invention relates to the technical field of water pumps, and particularly to an automatic pool pump and medicine filtering device. Background Art

[0002] The automatic pool pump and medicine filtering device is an automated device integrating a water pump and a filtering device, mainly used for the circulation, disinfection, and purification of pool water quality.

[0003] In the prior art, in a high-dose metering pump for a pool that is easy to disassemble and clean, disclosed in the Chinese patent document with the publication number CN211525109U, it is proposed that due to the relatively low pressure in the middle cavity, the drug fluid can be quickly sucked into the middle cavity. When spraying the drug fluid, under the pushing of the pump core, the pressure in the middle cavity is relatively high and the amount of drug fluid is relatively large, so that it can be quickly sprayed out, thereby improving the suction and spraying speeds of the drug fluid, facilitating the improvement of the metering pump drug delivery efficiency, and further realizing the high-dose delivery of the metering pump, which is suitable for the disinfection of the pool. However, consistent with the traditional method, in the process of pool water treatment by the traditional pump and medicine filtering device, although the filter element can preliminarily filter most of the particulate impurities, there is still a problem that fine impurities enter the through pipe along with the liquid medicine and gradually deposit at the bottom of the pipeline during operation. Once these deposits accumulate, they are likely to form blockages inside the pipeline, affecting the fluidity, resulting in a decrease in the system's medicine supply efficiency. Moreover, the traditional device mostly relies on manual cleaning of the deposits at regular intervals of shutdown, with cumbersome operations and high maintenance frequencies, which are extremely likely to cause system interruption or treatment delays. Especially in unattended or continuous operation scenarios, the stability is poor, it is difficult to ensure the continuous and accurate dosing of the liquid medicine, and in severe cases, it may even cause abnormal pipeline pressure or equipment damage. Therefore, the present application discloses an automatic pool pump and medicine filtering device. Summary of the Invention

[0015] Advantages of the present invention: 1. This automatic pool pump and medicine filtration device is equipped with a bypass component and a terminal filtration module. When the filtration system becomes blocked, the sliding plug block automatically opens the bypass channel under the pressure difference in the through pipe. While ensuring the continuous supply of medicine, the connecting rod driven by its linkage drives the movable filter plate to fit against the fixed filter plate. The mechanical ejection self-cleaning function of the blocked particles is realized by the staggered cooperation of the filtration holes and the ejector post structure, completing the on-line cleaning of the filter plate. This process is completely triggered by fluid pressure and automatically responds without additional control components. The structure is simple and the response is rapid. While improving the continuous operation ability of the system, it extends the service life of the filter plate, effectively reduces the maintenance frequency, and improves the overall operation efficiency and the stability of the liquid medicine dosing system.

[0016] 2. This automatic pool pump and medicine filtration device is equipped with a first and a second guide plate and a bottom sand scraping module. Some strongly sedimentable particulate impurities gradually deposit in the area below the filtration component as the liquid medicine flows. Since two inclined guide plates are arranged inside the through pipe, the particulate matter carried by the liquid flow gradually slides down under the action of gravity and the inclination angle of the guide plate. The first guide plate is located directly below the filter plate and can block the upper filtration residue from continuing to fall back, preventing the bottom of the filter element from being blocked. The second guide plate is located on one side and guides the impurities to concentrate and shift to the bottom of the through pipe for accumulation. When the bypass component automatically opens due to blockage, the connecting rod drives the scraper to move synchronously towards the side of the liquid outlet cavity. The bottom of the scraper closely adheres to the bottom of the through pipe and slides along the bottom surface, scraping and concentrating the deposited particulate impurities together from below the guide plate and guiding them to the area with a slag discharge structure for subsequent unified discharge.

[0017] 3. This automatic pool pump and medicine filtration device is equipped with a slag discharge module. The slag discharge module is equipped with a sedimentation cylinder and an inclined bottom plate structure, which can effectively collect the impurities swept by the bottom sand scraping module and prevent them from flowing back to pollute the filtration system. At the same time, in cooperation with the first closing plate and the second closing plate arranged oppositely on the slag discharge groove, through a multi-group spring and gear linkage structure, stable sealing in the closed state and synchronous opening at the moment of opening are realized, forming a short-term slag discharge channel. Under the high pressure of the pump body, the deposited impurities are quickly flushed out, ensuring high slag discharge efficiency and short response time without affecting the continuity of medicine supply. The core lies in the cooperation of the driving rod and the trigger block linked to the connecting rod, enabling the entire slag discharge action to be automatically completed during the bypass closing and resetting process without an independent control device, with a compact structure and reliable operation.

[0023] As Figures 1 to 11 shown, the automatic pool pump and medicine filtering device includes a pump body 1 and a mounting seat 4. A pump body inlet pipe 2 is provided on one side of the pump body 1, and a pump body outlet pipe 3 is provided on the top of the pump body 1; a filtering assembly, the filtering assembly is arranged above the mounting seat 4, one side of the filtering assembly is communicated with the pump body inlet pipe 2, and the filtering assembly is used for filtering the liquid medicine; a bypass assembly, the bypass assembly is arranged on one side of the filtering assembly, and the bypass assembly is used for assisting in discharging medicine when the inside of the filtering assembly is blocked; a cleaning assembly, the cleaning assembly is arranged inside the filtering assembly, and the cleaning assembly includes an end filtering module, a bottom sand scraping module, and a slag discharging module. The end filtering module is used for end filtering and self-cleaning itself synchronously when the bypass assembly is opened. The bottom sand scraping module is used for scraping the sundries at the bottom of the filtering assembly into the inside of the slag discharging module. The slag discharging module is used for driving the slag discharging module to be briefly opened for slag discharging operation during the process of the bypass assembly resetting after the filtering assembly is normal. Among them, the filtering assembly includes a through pipe 5 fixedly installed above the mounting seat 4. A filter 7 is arranged above one side of the through pipe 5, a filter inlet pipe 8 is arranged above the filter 7, a threaded section 6 is formed on the outer surface of one side of the through pipe 5, and the through pipe 5 is communicated with one side of the pump body 1 through the threaded section 6. A filter element 9 is arranged inside the filter 7, and the filter element 9 is detachably replaceable; After the pool water treatment system is started, the liquid medicine or potion first enters the filter 7 installed on the mounting base 4 through the filter inlet pipe 8. The filter element 9 in the filter 7 preliminarily filters the incoming liquid, intercepts particulate impurities, and the filtered liquid medicine enters the inlet pipe of the pump body 1 through the lower part of the through pipe 5. After being pressurized by the pump body 1, it is sent out from the outlet pipe of the pump body 1 to the pool system. During long-term operation, if the filter element 9 is blocked or the water flow resistance increases due to impurity accumulation, it can be disassembled for inspection and replacement. When the end filtration module is blocked by impurity accumulation, the bypass assembly is automatically opened, and the liquid medicine bypasses the end filtration module and continues to supply medicine through the bypass path, avoiding system interruption or alarm caused by blockage. The cleaning assembly starts to operate, and the end filtration module performs synchronous reverse self-cleaning in the bypass open state. The bottom sand scraping module starts, mechanically scrapes the sundries deposited at the bottom of the filter 7, and concentrates them to the slag discharging module; when the main filtration returns to normal and the bypass is closed, the slag discharging module is briefly opened to discharge the concentrated impurities from the system.

[0024] As Figures 1 to 4 shown, the bypass assembly includes a positioning housing 13 fixedly installed on the side of the through pipe 5 away from the threaded section 6. A liquid inlet cavity 14 communicating with the through pipe 5 is provided on one side of the positioning housing 13. An outlet liquid cavity 17 is provided on the side of the positioning housing 13 away from the through pipe 5. A fixing rod 16 is fixedly installed in the middle of the positioning housing 13. A sliding plugging block 18 is slidably sleeved on the side of the fixing rod 16 close to the liquid inlet cavity 14. A first return spring 19 is sleeved on the side of the sliding plugging block 18 away from the liquid inlet cavity 14, and the other end of the first return spring 19 is fixedly connected to the inner side of the outlet liquid cavity 17. The sliding plugging block 18 is used to block the communication between the liquid inlet cavity 14 and the outlet liquid cavity 17. A bypass outlet 15 is provided on the side of the outlet liquid cavity 17. A bypass pipe 21 is provided on the other side of the bypass outlet 15. A bypass inlet 22 is opened on the side of the through pipe 5 away from the positioning housing 13, and the other end of the bypass pipe 21 is connected to the bypass inlet 22. During normal operation of the system, the pump body 1 sucks in the liquid medicine for filtration through the filtration assembly, and the filtered liquid flows into the pump body 1 through the through pipe 5. When a blockage occurs and the liquid inlet is blocked, back pressure is generated in the through pipe 5, which in turn pushes the sliding plugging block 18 to move along the fixing rod 16 towards the outlet liquid cavity 17, compressing the first return spring 19, so that the originally blocked liquid inlet cavity 14 is connected to the outlet liquid cavity 17. The liquid medicine can enter the bypass pipe 21 through the bypass outlet 15 and then enter the downstream of the through pipe 5 again through the bypass inlet 22, bypassing the main filtration path to continue supplying medicine, ensuring that the pump body 1 does not interrupt the liquid supply. When the blockage of the filter element 9 is cleared, the through pipe 5 returns to normal, the flow rate of the main path returns to normal, the pressure drops, and the first return spring 19 pushes the sliding plugging block 18 back to its original position to re-close the bypass channel, so that the system returns to the main filtration path.

[0025] As Figure 3 、Figure 7 As shown, the end filtration module includes a fixed filter plate 10 fixedly installed on the side of the inner part of the through pipe 5 away from the positioning housing 13, and a movable filter plate 11 slidably installed on the side of the inner part of the through pipe 5 away from the positioning housing 13. The fixed filter plate 10 and the movable filter plate 11 are arranged one in front of the other. Both the fixed filter plate 10 and the movable filter plate 11 are inclined. A connecting rod 20 is fixedly connected to the side of the sliding plugging block 18 away from the first return spring 19. The connecting rod 20 penetrates through the fixed filter plate 10 and is fixedly connected to one side of the movable filter plate 11. The filter holes on the fixed filter plate 10 and the movable filter plate 11 are arranged staggeredly. Ejector posts 12 are arranged on the opposite surfaces of the fixed filter plate 10 and the movable filter plate 11. A number of ejector posts 12 respectively correspond to the filter holes on the fixed filter plate 10 or the movable filter plate 11. When the long-term operation of the filtration component causes the filter element 9 or the filter plate to be blocked and the flow rate of the through pipe 5 to decrease, the system pressure rises. The sliding plugging block 18 is pushed to slide towards the liquid outlet cavity 17 against the elastic force of the first return spring 19. While opening the bypass path, the integrated connecting rod 20 connected to it moves forward synchronously, driving the movable filter plate 11 to approach the fixed filter plate 10. Since the filter holes of the two filter plates are distributed staggeredly, during the process of their gradual fitting at this time, a number of ejector posts 12 arranged on the surface of the filter plate start to enter the holes of the other filter plate, and under the action of mechanical ejection pressure, the blocked particles are forcibly ejected from the holes, completing the self-cleaning action at the end. After the cleaning is completed, while the system resumes smoothness and the pressure drops, the sliding plugging block 18 returns to its original position under the action of the return spring, and the connecting rod 20 and the movable filter plate 11 also retreat to their original positions, restoring the normal filtration structure state. The whole action is completed by the differential pressure linkage when the bypass is enabled, without external energy consumption control.

[0026] As Figure 3 、 Figure 5 As shown, inclined first guide plate 39 and second guide plate 40 are also arranged staggeredly inside the through pipe 5. The first guide plate 39 is located directly below the filtration component, and the second guide plate 40 is located on one side below the filtration component. The first guide plate 39 and the second guide plate 40 are arranged one above the other. The bottom sand scraping module includes a scraper 41 closely attached to one side of the first guide plate 39, and the scraper 41 is fixedly sleeved on the side of the connecting rod 20 away from the positioning housing 13. The bottom of the scraper 41 closely adheres to the bottom of the through pipe 5, and the top of the scraper 41 is set as an inclined surface to reduce impurities from falling between the first guide plate 39 and the scraper 41. During the operation of the pool liquid medicine filtration system, some particulate impurities with strong sedimentation gradually deposit in the area below the filtration component as the liquid medicine flows. Since there are two inclined guide plates inside the through pipe 5, the particulate matter carried by the liquid flow gradually slides down under the guidance of gravity and the inclination angle of the guide plates. The first guide plate 39 is located directly below the filter plate, which can block the upper filter residue from continuing to fall back and prevent the bottom of the filter element 9 from being blocked. The second guide plate 40 is located on one side, guiding the impurities to concentrate and shift and accumulate towards the bottom of the through pipe 5. When the bypass component is automatically opened due to blockage, the connecting rod 20 drives the scraper 41 to move synchronously towards the liquid outlet cavity 17. The bottom of the scraper 41 closely adheres to the bottom of the through pipe 5 and slides along the bottom surface, scraping and concentrating the deposited particulate debris together from below the guide plates and guiding it to the area provided with a slag discharge structure for subsequent unified discharge.

[0027] As Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 As shown, the slag discharge module includes a sedimentation cylinder 23 provided between the through pipe 5 and the bypass component, and the sedimentation cylinder 23 is set to sink. The bottom of the sedimentation cylinder 23 is provided with a bottom plate 24 inclined towards the middle. A rectangular slag discharge groove 25 is provided in the middle of the bottom plate 24. Sliding grooves are opened on both sides of the slag discharge groove 25, and a first closing plate 26 and a second closing plate 27 are slidably installed in the sliding grooves. A plurality of second return springs 29 are provided on the sides of the first closing plate 26 and the second closing plate 27 away from each other, and the plurality of second return springs 29 are respectively fixed to the side of the sliding groove away from the slag discharge groove 25. The opposite surfaces of the first closing plate 26 and the second closing plate 27 are arranged as inclined surfaces that fit each other. A fixed seat 36 is fixedly installed in the middle of the top surface of the first closing plate 26. A trigger block 37 is slidably installed inside the fixed seat 36. A plurality of third return springs 38 are fixedly connected to the bottom surface of the trigger block 37, and the bottom surface of the third return springs 38 is fixedly connected to the inner bottom surface of the fixed seat 36. Both sides of the top surface of the trigger block 37 are arranged to be inclined. A driving rod 28 is also fixedly sleeved in the middle of the connecting rod 20. The initial position of the driving rod 28 is in the direction close to the scraper 41. A first extension plate 30 is provided on one side of the first closing plate 26. A plurality of first meshing teeth 31 are provided on one side of the bottom of the first extension plate 30. A second extension plate 32 is provided on one side of the second closing plate 27. A second meshing tooth 33 is provided on one side of the second extension plate 32. A positioning rod 34 is also provided on one side of the inner part of the bottom plate 24. A gear 35 is provided on one side of the positioning rod 34. The upper part of the gear 35 meshes with the first meshing teeth 31, and the lower part of the gear 35 meshes with the second meshing teeth 33. When the first extension plate 30 moves, it will drive the second extension plate 32 to move in the opposite direction; After the swimming pool pump filter device has been running for a long time, impurities scraped off by the bottom sand scraping module will gradually accumulate in the bottom sedimentation cylinder 23. At this time, if the bypass is triggered to open, the connecting rod 20 drives the driving rod 28 to move synchronously toward the liquid outlet cavity 17. During the movement toward the liquid outlet cavity 17, the driving rod 28 first squeezes the trigger block 37. Since the first closing plate 26 and the second closing plate 27 are in a close fit at this time, the squeezing force will only drive the first closing plate 26 to squeeze the second closing plate 27. In this squeezing direction, the first closing plate 26 will not be pushed to squeeze the second closing plate 27 to open. Only the two closing plates will be considered. The driving rod 28 contacts the inclined surface of the trigger block 37 during operation. Due to the buffering effect of the inclined surface structure and the third reset spring 38, the driving rod 28 will gradually compress the trigger block 37 and move it toward the inside of the fixed seat 36, and the driving rod 28 will gradually pass over it without destroying the closed state. When the filtration returns to normal and the bypass assembly is closed, the connecting rod 20 begins to reset in the reverse direction, driving the driving rod 28 to return to its original position, and the driving rod 28 contacts the other side inclined surface of the trigger block 37 again. After this inclined surface contacts the driving rod 28, because the first closing plate 26 is movable in this moving direction, The driving rod 28 is designed to be opened and closed by movement, so the driving rod 28 first presses against the inclined surface to drive the trigger block 37 to drive the first closing plate 26 to move, and at the same time pushes the first closing plate 26 connected thereto to open. At the same time, the gear 35 starts to rotate under the action of the first meshing tooth 31, and drives the second meshing tooth 33 meshing therewith to make the second closing plate 27 open synchronously in the opposite direction, forming a short-term slag discharge channel. Since the sedimentation cylinder 23 is connected to the pump body 1, the high-pressure liquid of the pump body 1 impacts the slag discharge groove 25 at the moment of opening, and is quickly ejected with impurities, realizing the short-term slag discharge function. When 20 continues to reset to the initial position, the driving rod 28 disengages from the trigger block 37, and the trigger block 37 returns to its original position under the action of the third reset spring 38. The first closing plate 26 and the second closing plate 27 are quickly closed under the drive of the second reset spring 29 to block the slag discharge groove 25. During this process, the torsion spring structure arranged on the second closing plate 27 pulls the closing plate to tilt and rotate when it is opened. When the closing plate is closed, its inclined edge first contacts the surface of the first closing plate 26, and slides and resets along its inclined surface during the continued closing process, thereby automatically scraping off impurities thereon and improving the cleanliness and sealing effect of the closed interface.
