Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and specifically to a filtering and purifying device for garden pools. Background Art

[0002] In garden landscapes, pools, as important components, can not only beautify the environment but also regulate the local microclimate and provide a living space for animals and plants. However, due to their openness and particularity, the water quality of garden pools is easily affected by various factors and deteriorates. Garden pools are usually in direct contact with the external environment, and sundries such as leaves, dust, insects, and bird droppings will continuously fall into the pool. Over time, these sundries accumulate in the pool, not only affecting the beauty of the pool but also becoming a breeding ground for microorganisms. The massive reproduction of microorganisms consumes the dissolved oxygen in the water, leading to water quality deterioration and unpleasant odors. For example, in the hot summer season, pools that are not cleaned in time often experience a large proliferation of algae, making the water body appear green or blue-green, seriously damaging the beauty of the garden landscape.

[0003] During the filtering and purifying process, a filtering structure is often used to preliminarily separate large particulate sundries (such as insect corpses) in the water. However, after long-term use of existing filtering and purifying devices for garden pools, the large particulate sundries on one side of the filter screen accumulate more and more, resulting in the blockage of the filter screen. Once the filter screen is blocked, it will inevitably affect the filtering efficiency of sewage. Therefore, in view of the above situation, there is an urgent need to provide a filtering and purifying device for garden pools to overcome the deficiencies in current practical applications. Summary of the Invention

A scraper for scraping off the large particulate sundries accumulated inside the filtering component is slidably installed on the strip-shaped box, and an active traction component for pulling the scraper back to its original position is further provided inside the strip-shaped box. When water enters the filtering component, the scraper moves downward under the impact force of the water. After the scraper moves down to a specified position, the filtering component starts to filter the water, and cooperates with the active traction component to drive the scraper back to its original position, so that the scraper scrapes off the large particulate sundries.

[0006] As a further solution of the present invention: The filtering component includes: A filter cartridge, which is fixedly installed on a base, and filter holes II are formed on the side wall of the filter cartridge; And a control cartridge sleeved on the filter cartridge, which is rotationally matched with the filter cartridge, and filter holes I for communicating with the filter holes II are formed on the side wall of the control cartridge.

[0008] As a further scheme of the present invention: A strip-shaped hole for cooperating with a cleaning and scraping assembly is formed on the side wall of the rotating pipe.

[0009] As a further scheme of the present invention: The feed pipe is a telescopic pipe fitting, and a plurality of branch pipes are arranged at one end of the feed pipe far away from the water guide cover.

[0010] As a further scheme of the present invention: The part of the base located inside the filter cartridge is of a conical structure.

[0011] As a further scheme of the present invention: The aperture of the filter hole II is smaller than the aperture of the filter hole I.

[0012] As a further scheme of the present invention: The active traction assembly includes: A moving block, which is slidably installed in a strip-shaped box; An elastic member for pulling the moving block towards the base side, one end of the elastic member is fixedly connected to the bottom of the strip-shaped box, and the other end of the elastic member is fixedly connected to the moving block; And a traction pipe fixedly installed on the moving block, a round hole for the traction pipe to penetrate is formed on the side wall of the strip-shaped box far away from the base end, and one end of the traction pipe far away from the moving block passes through the round hole and is fixedly connected to the scraping plate.

When water enters the filter assembly, the scraper moves down due to the impact of the water. After the scraper moves down to the specified position, the filter assembly starts to filter the water, and cooperates with the active traction assembly to drive the scraper to move up. When the scraper moves up, it can push the water to impact the filter assembly, thereby improving the filtering efficiency. At the same time, the scraper moving up and down can effectively scrape off large particles of debris to avoid blockage. The filtered water will be discharged through the drain pipe and return to the garden pool, or undergo further purification treatment; Through the linkage design of the scraping component and the filtering component, large particles of debris are automatically scraped off during the filtering process, effectively preventing the filter hole from being blocked and ensuring long-term stable filtering efficiency; In the water inlet stage, when the water guide hole 1 and the water guide hole 2 overlap, the filter hole 1 and the filter hole 2 are staggered, and the water flow pushes the scraper to move downward to preliminarily scrape off impurities. In the filtration stage, when the water guide hole 1 and the water guide hole 2 are staggered, the filter hole 1 and the filter hole 2 overlap, and the scraper moves upward under the action of the elastic member to accelerate drainage and scrape the filter cylinder for the second time to improve the filtration efficiency; The airflow counter-flow design of the jet hole promotes the mixing of the agent and water when adding flocculants, improves the flocculation and sedimentation effect, and is suitable for the purification of high turbidity water bodies; The impact force of water flow is used to drive the scraper to move, combined with elastic reset, to reduce extra energy consumption and achieve a self-cleaning cycle; The scraping assembly and the filtering assembly are arranged in coordination with each other to avoid the problem that after long-term use of the existing garden pond filtering and purification device, large particles of debris accumulate on one side of the filtering screen, thereby causing the filtering screen to be blocked. Once the filtering screen is blocked, the filtering efficiency of the sewage is bound to be affected. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The following further explains and illustrates the present invention in conjunction with specific embodiments.

[0028] Please refer to Figures 1-6 , a garden pool filtration and purification device provided by an embodiment of the present invention, the garden pool filtration and purification device includes: A housing 1 and a base 8 provided at the bottom of the housing 1, and a drain pipe 9 is also provided on the base 8; wherein the base 8 and the housing 1 are detachably connected; A filtration component located inside the housing 1, and the filtration component is provided on the base 8; And a cleaning and scraping component provided inside the filtration component. The cleaning and scraping component includes a strip-shaped box 12 fixedly installed inside the base 8. A scraper 13 for scraping off large particle debris accumulated inside the filtration component is slidably installed on the strip-shaped box 12. And an active traction component for pulling the scraper 13 to reset is also provided inside the strip-shaped box 12. When water enters the filtration component, the scraper 13 moves downward under the impact force of water. After the scraper 13 moves downward to a specified position, the filtration component starts to filter the water, and cooperates with the active traction component to drive the scraper 13 to reset, so that the scraper 13 scrapes off large particle debris.

[0029] In an embodiment of the present invention, when the filtering component pauses working, the water in the garden pool is introduced into the filtering component. The water can be pumped into the filtering component by a water pump. When water enters the filtering component, the scraper 13 moves downward under the impact force of the water. After the scraper 13 moves downward to a specified position, the filtering component starts to filter the water, and cooperates with the active traction component to drive the scraper 13 to move upward. When the scraper 13 moves upward, it can push the water to impact on the filtering component, improving the filtering efficiency. At the same time, the scraper 13 moving up and down can effectively scrape off large particle debris, avoiding blockage. The water that has passed through the filtration will be discharged through the drain pipe 9 and return to the garden pool again, or undergo further purification treatment; compared with the prior art, through the combined setting of the cleaning component and the filtering component, the present invention avoids the problem that in the existing garden pool filtering and purification device, after long-term use, more and more large particle debris accumulates on one side of the filter net, resulting in blockage of the filter net, and once the filter net is blocked, it will inevitably affect the filtering efficiency of sewage.

[0030] In an embodiment of the present invention, please refer to Figures 1-6 , the filtering component includes: A filter cylinder 10, which is fixedly installed on the base 8, and filter holes II 11 are provided on the side wall of the filter cylinder 10; And a control cylinder 2 sleeved on the filter cylinder 10. The control cylinder 2 is rotationally matched with the filter cylinder 10, and filter holes I 3 for communicating with the filter holes II 11 are provided on the side wall of the control cylinder 2; The filtering component further includes: A water guide cover 4, which is fixedly installed on the top of the control cylinder 2, and a closed cavity is formed between the water guide cover 4 and the top of the control cylinder 2. A feed pipe 7 communicating with the closed cavity is provided on the housing 1; A rotating pipe 5 rotatably installed on the top of the housing 1. The rotating pipe 5 is fixedly connected to the water guide cover 4, and a motor 6 for driving the rotating pipe 5 to rotate is further provided on the housing 1; And a water guide hole II 21 opened on the top of the filter cylinder 10. A water guide hole I 20 for communicating with the water guide hole II 21 is opened on the top of the control cylinder 2; When the water guide hole I 20 coincides with the water guide hole II 21, the filter holes I 3 are staggered from the filter holes II 11; When the water guide hole I 20 is staggered from the water guide hole II 21, the filter holes I 3 coincide with the filter holes II 11; A strip hole for cooperating with the cleaning component is opened on the side wall of the rotating pipe 5; The feed pipe 7 is a telescopic pipe fitting, and multiple branch pipes are provided at one end of the feed pipe 7 away from the water guide cover 4; The part of the base 8 located inside the filter cylinder 10 is of a conical structure, which is convenient for guiding water to all around, thereby improving the filtering efficiency; The aperture of the second filter hole 11 is smaller than that of the first filter hole 3, so that most of the sundries will be left inside the filter cylinder 10.

[0031] In this embodiment, when in use, the water inlet pipe 7 is used to facilitate the introduction of water into the sealed cavity, or the water and the treatment agent are introduced into the sealed cavity at the same time. The treatment agent can be a flocculant and can be selected according to actual usage requirements. When water enters, the motor 6 drives the rotating pipe 5 to rotate. The rotating pipe 5 drives the control cylinder 2 to rotate by means of the water guide cover 4, so that the first water guide hole 20 coincides with the second water guide hole 21. At this time, the first filter hole 3 is staggered from the second filter hole 11, and the water will enter above the scraper 13. Since the first filter hole 3 is staggered from the second filter hole 11, the water cannot be discharged, thus pushing the scraper 13 to move downward. During the downward movement of the scraper 13, a primary scraping of large-particle sundries on the inner wall of the filter cylinder 10 is realized. When the scraper 13 moves downward to a specified position (the water inlet volume can be controlled according to requirements, that is, the greater the downward movement distance of the scraper 13, the greater the water inlet volume), the motor 6 drives the rotating pipe 5 to rotate in the reverse direction, so that the first water guide hole 20 is staggered from the second water guide hole 21. At this time, the water cannot continue to enter the filter cylinder 10. After the first filter hole 3 coincides with the second filter hole 11, the water in the filter cylinder 10 will be discharged outward through the second filter hole 11 and the first filter hole 3, realizing the filtering function.

[0032] In an embodiment of the present invention, please refer to Figures 1-6 , the active traction assembly includes: A moving block 17, which is slidably installed in the strip-shaped box 12; An elastic member 18 for pulling the moving block 17 toward the base 8. One end of the elastic member 18 is fixedly connected to the bottom of the strip-shaped box 12, and the other end of the elastic member 18 is fixedly connected to the moving block 17; the elastic member 18 can be an elastic rope and is not limited herein; And a traction pipe 15 fixedly installed on the moving block 17. A circular hole for the traction pipe 15 to pass through is opened on the side wall of the strip-shaped box 12 far from the base 8, and one end of the traction pipe 15 far from the moving block 17 passes through the circular hole and is fixedly connected to the scraper 13; A first cavity communicating with the traction pipe 15 is opened in the moving block 17, and an air guide hole 19 communicating with the first cavity is opened on the moving block 17. A second cavity communicating with the traction pipe 15 is provided inside the scraper 13, and an air jet hole 14 communicating with the second cavity is opened on the surface of the scraper 13. An air inlet pipe 16 is provided at the top of the strip-shaped box 12, and circular holes for the air inlet pipe 16 to pass through are opened at the top of the filter cylinder 10, the top of the control cylinder 2, and the water guide cover 4; Check valves are provided in both the air inlet pipe 16 and the air guide hole 19.

[0033] In this embodiment, after the first filter hole 3 and the second filter hole 11 coincide, water will be discharged outward through the first filter hole 3 and the second filter hole 11. At this time, the elastic member 18 will pull the moving block 17 downward. Through the cooperation with the traction tube 15, the moving block 17 will pull the scraper 13 upward. By the thrust of the scraper 13, the flow of water through the first filter hole 3 and the second filter hole 11 can be accelerated. At the same time, the upward moving scraper 13 will achieve secondary scraping, improve the cleaning effect, and keep the second filter hole 11 unobstructed. When the moving block 17 moves downward, the external gas can be sucked into the strip box 12 through the air inlet pipe 16. When the moving block 17 moves upward, the gas in the strip box 12 can be compressed and introduced into the traction tube 15 through the air guide hole 19, and then introduced into the cavity two of the scraper 13 through the traction tube 15, and finally sprayed out through the air spray hole 14 to achieve the counterflush with water. In the case of using a flocculant, the fusion effect of the flocculant and water can be improved; After long-term use, the base 8 and the scraping assembly can be removed for cleaning.

[0034] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
