Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to a garden pond filtering and purifying device. Background Art

[0002] Ponds, as a crucial component of garden landscapes, not only beautify the environment but also regulate the local microclimate and provide a habitat for plants and animals. However, due to their openness and specialized nature, the water quality of garden ponds is susceptible to a variety of factors, leading to deterioration. Garden ponds are often in direct contact with the outside world, and debris such as leaves, dust, insects, and bird droppings constantly drift into the water. Over time, this debris accumulates in the pond, not only affecting its aesthetics but also creating a breeding ground for microorganisms. The proliferation of these microorganisms depletes dissolved oxygen in the water, leading to deterioration in water quality and the emission of unpleasant odors. For example, during the hot summer months, ponds that are not promptly cleared of debris often experience algae blooms, causing the water to appear green or bluish-green, severely detracting from the aesthetic appeal of the garden landscape.

[0003] During the filtration and purification process, a filter structure is often used to initially separate large particles of debris (such as dead insects) from the water. However, after long-term use, existing garden pond filtration and purification devices tend to accumulate large particles on one side of the filter, causing the filter to become clogged. Once the filter becomes clogged, the filtration efficiency of the sewage is inevitably affected. Therefore, in response to the above situation, there is an urgent need to provide a garden pond filtration and purification device to overcome the shortcomings of current practical applications. Summary of the Invention

[0004] The purpose of the present invention is to provide a garden pond filtering and purification device, aiming to solve the problems in the above background technology.

When water enters the filter assembly, the scraper moves downward due to the impact force 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 reset, so that the scraper can scrape off large particles of debris.

[0009] As a further solution of the present invention: the filter assembly includes:

[0010] The filter cartridge is fixedly mounted on the base, and a second filter hole is opened on the side wall of the filter cartridge;

[0011] and a control cylinder sleeved on the filter cylinder, wherein the control cylinder and the filter cylinder are rotatably matched, and a filter hole 1 for communicating with the filter hole 2 is opened on the side wall of the control cylinder.

[0012] As a further solution of the present invention: the filter assembly further includes:

[0013] A water guide cover is fixedly mounted on the top of the control cylinder, and a closed cavity is formed between the water guide cover and the top of the control cylinder. A feed pipe connected to the closed cavity is provided on the housing;

[0014] A rotating pipe is rotatably mounted on the top of the housing, wherein the rotating pipe is fixedly connected to the water guide cover, and a motor is also provided on the housing for driving the rotating pipe to rotate;

[0015] and a second water guide hole opened on the top of the filter cylinder, and a first water guide hole opened on the top of the control cylinder for communicating with the second water guide hole;

[0016] When the water guide hole 1 and the water guide hole 2 coincide, the filter hole 1 and the filter hole 2 are staggered;

[0017] When the water guide hole 1 is staggered with the water guide hole 2, the filter hole 1 is overlapped with the filter hole 2.

[0018] As a further solution of the present invention: a strip-shaped hole for use with a scraping assembly is opened on the side wall of the rotating tube.

[0019] As a further solution of the present invention: the feed pipe is a telescopic pipe, and a plurality of branch pipes are provided at one end of the feed pipe away from the water guide shield.

[0020] As a further solution of the present invention: the portion of the base located inside the filter cartridge is a conical structure.

[0021] As a further solution of the present invention: the aperture of the second filter hole is smaller than the aperture of the first filter hole.

[0022] As a further solution of the present invention: the active traction assembly includes:

[0023] A moving block, the moving block being slidably mounted in the bar box;

[0024] An elastic member for pulling the moving block toward one side of the base, wherein one end of the elastic member is fixedly connected to the bottom of the strip box, and the other end of the elastic member is fixedly connected to the moving block;

[0025] And a traction tube fixedly installed on the moving block, a round hole for the traction tube to pass through is opened on the side wall of the strip box away from the base, and the end of the traction tube away from the moving block passes through the round hole and is fixedly connected to the scraper.

[0026] As a further solution of the present invention: a cavity one connected to the traction tube is provided in the moving block, and an air guide hole connected to the cavity one is provided on the moving block; a cavity two connected to the traction tube is provided in the scraper, and an air jet hole connected to the cavity two is provided on the surface of the scraper; an air intake pipe is provided on the top of the strip box, and circular holes for the air intake pipe to pass through are provided on the top of the filter cylinder, the top of the control cylinder and the water guide cover.

[0027] As a further solution of the present invention: a one-way valve is provided in both the air inlet pipe and the air guide hole.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] When the filter assembly is suspended, the water in the garden pool is introduced into the filter assembly, and the water can be pumped into the filter assembly by a water pump. When water enters the filter assembly, the scraper moves downward due to the impact of the water. After the scraper moves down to the designated position, the filter assembly starts to filter the water, and cooperates with the active traction assembly to drive the scraper upward. When the scraper moves upward, it can push the water to impact the filter assembly, thereby improving the filtration 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 returned to the garden pool, or further purified.

[0030] The linkage design of the scraping component and the filtering component automatically scrapes away large particles of debris during the filtration process, effectively preventing the filter holes from being blocked and ensuring long-term stable filtration efficiency.

[0031] During 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 downward to preliminarily scrape off impurities. During 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, accelerating drainage and scraping the filter cartridge for the second time, thereby improving filtration efficiency.

[0032] The airflow counter-flow design of the air jet holes 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;

[0033] The impact force of water flow is used to drive the scraper to move, combined with elastic reset, to reduce additional energy consumption and achieve a self-cleaning cycle;

[0034] The present invention avoids the problem of large particles of debris accumulating on one side of the filter screen after long-term use in the existing garden pond filtering and purification device by coordinating the scraping component with the filtering component, thereby causing the filter screen to be clogged. Once the filter screen is clogged, the filtration efficiency of the sewage is inevitably affected. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0046] The present invention will be further explained below with reference to specific embodiments.

[0047] See also Figures 1-6 The embodiment of the present invention provides a garden pond filtering and purifying device, the garden pond filtering and purifying device comprising:

[0048] The housing 1 and the base 8 are provided at the bottom of the housing 1. The base 8 is also provided with a drain pipe 9. The base 8 and the housing 1 are detachably connected.

[0049] A filter assembly located in the housing 1, wherein the filter assembly is disposed on a base 8;

[0050] And a scraping assembly is arranged in the filter assembly, which includes a strip box 12 fixedly installed in the base 8, and a scraper 13 is slidably installed on the strip box 12 for scraping off large particles of debris accumulated in the filter assembly, and an active traction assembly is also provided in the strip box 12 for pulling the scraper 13 to reset. When water enters the filter assembly, the scraper 13 moves downward due to the impact force of the water. After the scraper 13 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 13 to reset, so that the scraper 13 can scrape off large particles of debris.

[0051] When the filter element is suspended, the water in the garden pool is introduced into the filter element, and the water can be pumped into the filter element by using a water pump. When water enters the filter element, the scraper 13 moves downward by the impact of the water. After the scraper 13 moves down to the specified position, the filter element 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 the filter element, thereby improving the filtering efficiency. At the same time, the scraper 13 moving up and down can effectively scrape off large particles of debris to avoid clogging. The filtered water will be discharged through the drain pipe 9 and return to the garden pool, or undergo further purification treatment. Compared with the prior art, the present invention avoids the problem that large particles of debris on one side of the filter screen accumulate more and more after long-term use in the existing garden pool filtering and purification device through the coordinated arrangement of the scraping component and the filter component, thereby causing clogging of the filter screen. Once the filter screen is clogged, it will inevitably affect the filtration efficiency of the sewage.

[0052] In one embodiment of the present invention, see Figures 1-6 , the filtering component comprises:

[0053] The filter cartridge 10 is fixedly mounted on the base 8, and a filter hole 11 is formed on the side wall of the filter cartridge 10;

[0054] and a control cylinder 2 sleeved on the filter cylinder 10, wherein the control cylinder 2 and the filter cylinder 10 are rotatably matched, and a filter hole 1 3 is formed on the side wall of the control cylinder 2 for communicating with the filter hole 2 11;

[0055] The filter assembly further comprises:

[0056] The water guide cover 4 is fixedly mounted 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. The housing 1 is provided with a feed pipe 7 connected to the closed cavity;

[0057] The rotating tube 5 is rotatably mounted on the top of the housing 1. The rotating tube 5 is fixedly connected to the water guide cover 4. The housing 1 is also provided with a motor 6 for driving the rotating tube 5 to rotate.

[0058] A second water guide hole 21 is provided on the top of the filter cylinder 10 , and a first water guide hole 20 is provided on the top of the control cylinder 2 for communicating with the second water guide hole 21 ;

[0059] When the water guide hole 1 20 and the water guide hole 2 21 overlap, the filter hole 1 3 and the filter hole 2 11 are staggered;

[0060] When the water guide hole 1 20 and the water guide hole 2 21 are staggered, the filter hole 1 3 and the filter hole 2 11 overlap;

[0061] The side wall of the rotating tube 5 is provided with a strip-shaped hole for use with the scraping assembly;

[0062] The feed pipe 7 is a retractable pipe, and a plurality of branch pipes are provided at one end of the feed pipe 7 away from the water guide cover 4;

[0063] The portion of the base 8 located inside the filter cartridge 10 is a conical structure, which facilitates guiding water to the surroundings, thereby improving the filtration efficiency;

[0064] The aperture of the second filter hole 11 is smaller than that of the first filter hole 3 , so that most of the debris will be retained in the filter cartridge 10 .

[0065] In this embodiment, when in use, the feed pipe 7 is used to facilitate the introduction of water into the closed cavity, or the water and the treatment agent are introduced into the closed cavity at the same time, wherein the treatment agent can be a flocculant, which can be selected according to actual use needs. When water is introduced, the motor 6 is used to drive the rotating tube 5 to rotate, and the rotating tube 5 will use the water guide cover 4 to drive the control cylinder 2 to rotate, so that the water guide hole 1 20 and the water guide hole 2 21 coincide with each other. At this time, the filter hole 1 3 and the filter hole 2 11 are staggered, and the water will enter the top of the scraper 13. Since the filter hole 1 3 and the filter hole 2 11 are staggered, the water cannot be discharged, thereby pushing the scraper 13 to move. The plate 13 moves downward, and the scraper 13 scrapes the large particles of debris on the inner wall of the filter cartridge 10 during the downward movement. When the scraper 13 moves down to the specified position (the water intake can be controlled according to demand, that is, the greater the downward movement distance of the scraper 13, the greater the water intake), the motor 6 is used to drive the rotating tube 5 to rotate in the opposite direction, so that the water guide hole 1 20 and the water guide hole 2 21 are staggered. At this time, water will not be able to continue to enter the filter cartridge 10, and after the filter hole 1 3 overlaps with the filter hole 2 11, the water in the filter cartridge 10 will be discharged outward through the filter hole 2 11 and the filter hole 1 3, thereby realizing the filtering function.

[0066] In one embodiment of the present invention, see Figures 1-6 , the active traction assembly includes:

[0067] A moving block 17 slidably mounted in the strip box 12 ;

[0069] and a traction tube 15 fixedly mounted on the moving block 17. A circular hole for the traction tube 15 to pass through is opened on the side wall of the strip box 12 away from the base 8, and the end of the traction tube 15 away from the moving block 17 passes through the circular hole and is fixedly connected to the scraper 13;

[0070] The movable block 17 has a cavity 1 in communication with the traction tube 15, and an air guide hole 19 in communication with the cavity 1 is formed on the movable block 17. The scraper 13 has a cavity 2 in communication with the traction tube 15, and an air jet hole 14 in communication with the cavity 2 is formed on the surface of the scraper 13. An air inlet pipe 16 is provided at the top of the strip box 12, and a circular hole for the air inlet pipe 16 to pass through is formed on the top of the filter cylinder 10, the top of the control cylinder 2, and the water guide cover 4.

[0071] One-way valves are provided in the air inlet pipe 16 and the air guide hole 19 .

[0072] The filter 11 is then drawn out of the water, which is then drawn out of the filter 11. The water is then drawn out of the filter 11, which is then drawn out of the filter 11. The water is then drawn out of the filter 11, which is then drawn out of the filter 11. The water is then drawn out of the filter 11, which is then drawn out of the filter 11.

[0073] After long-term use, the base 8 and the scraping assembly can be disassembled for cleaning.
