Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically a water pump with a self-cleaning function. Background Technology

[0002] A water pump is a mechanical device used to move liquids (usually water) from one place to another. It is powered by a mechanical or electrical source, causing the liquid to flow through pipes or piping systems. Water pumps are commonly used in various industrial, agricultural, and domestic applications, including water supply systems, drainage systems, cooling systems, and irrigation systems.

[0003] A water pump works by using rotating or vibrating mechanical parts, such as impellers, screws, or pistons, to generate pressure, drawing in liquid and propelling it to a target location. Based on different working principles and application requirements, water pumps can be classified into various types, including centrifugal pumps, positive displacement pumps, axial flow pumps, and mixed flow pumps.

[0004] According to a public announcement of a self-cleaning water pump (publication number: CN113074109A), the above application describes a filter device installed at the water inlet to filter the water flow, preventing large particles such as mud and sand from entering the pump's interior and ensuring its cleanliness. The pump's internal components are cleaned by a baffle fan that rotates under the impact of the water flow. This rotating baffle fan pushes a protrusion to vibrate the filter screen within the mounting groove, dislodging large particles adhering to the filter screen and preventing them from clogging the screen and affecting its filtration efficiency. This ensures the pump's internal cleanliness and achieves automatic cleaning.

[0005] However, while this application addresses the filter cleaning issue to some extent, it still has some shortcomings in practical applications. Specifically, when cleaning impurities on the filter surface, the application only uses vibration to shake them off, without effectively collecting and treating the shaken-off impurities. This means that the shaken-off impurities remain near the inlet, and over time, these impurities may re-accumulate and adhere to the filter screen, or enter other parts of the water pump, posing a potential threat to the pump's operating efficiency and stability. Utility Model Content

[0006] The purpose of this invention is to provide a water pump with a self-cleaning function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a water pump with a self-cleaning function, comprising a water pump body, wherein an inlet pipe is fixed to the suction end of the water pump body, and the surface and interior of the inlet pipe are provided with a collection component for collecting gravel particles and a cleaning component for facilitating the cleaning of gravel particles and preventing filter clogging, wherein the collection component includes:

[0008] A collection box is fixed below the water inlet pipe and is connected to the water inlet pipe. A sealing door is installed on the surface of the collection box.

[0009] Preferably, the collection assembly further includes an annular groove, which is formed on the inner side of the collection box. A slider is slidably connected to the inner wall of the annular groove. A spring is fixed to the surface of the slider. The end of the spring away from the slider is fixed to the inner wall of the annular groove. An arc-shaped filter plate is fixed to the side of the slider away from the spring. A notch is formed at the top of the collection box. An abutment block is fixed to the surface of the arc-shaped filter plate. When the surface of the linkage rod abuts against the surface of the abutment block, the abutment block can drive the arc-shaped filter plate and the slider to move in the annular groove. The notch of the collection box opens, and the swept-off and shaken-off gravel particles enter the collection box. When the linkage rod no longer abuts against the surface of the abutment block, the slider and the arc-shaped filter plate return to their original positions, blocking the notch of the collection box and preventing the gravel particles inside from escaping from the collection box.

[0010] Preferably, the cleaning assembly includes a base plate fixed to the surface of the filter screen. An impeller is rotatably connected to the side of the base plate away from the filter screen. A fixing rod is fixed to the surface of the impeller. A connecting groove is formed on the surface of the fixing rod. A sliding rod is slidably connected to the inner wall of the connecting groove. A second spring is fixed to the surface of the sliding rod. The end of the second spring away from the sliding rod is fixed to the inner wall of the connecting groove. A groove is formed on the surface of the impeller. A striking rod is hinged to the inner wall of the groove. A third spring is fixed to the surface of the striking rod. The end of the third spring away from the striking rod is fixed to the inner wall of the groove. The striking rod is close to the filter screen. One protrusion is fixed to one side of the screen, and another protrusion is fixed to the surface of the filter screen. When the water pump body is started, the impeller rotates under the drive of the water flow. The fixed rod and sliding rod rotate synchronously with the impeller. The brushes on the surface of the fixed rod and sliding rod can clean the surface of the filter screen. At the same time, the striking rod rotates, causing protrusion one to rotate. When protrusion one and protrusion two come into contact, the striking rod flips over and spring three is compressed. When protrusion one no longer comes into contact with protrusion two, spring three is released, which allows the striking rod to drive protrusion one to reset. At the same time, protrusion one will hit the filter screen, causing the filter screen to vibrate and shake off gravel particles, thus enabling the water pump to perform self-cleaning.

[0011] Preferably, a brush is fixed to the side of the slide rod and the fixing rod near the filter screen to facilitate the cleaning of gravel particles.

[0012] Preferably, both the first and second protrusions are spherical and abut against each other, allowing the striking rod to flip without affecting its normal movement.

[0013] Preferably, a connecting rod is fixed to the surface of the end of the slide rod away from the second spring. When the slide rod rotates, it can contact the surface of the contact block, so that the arc-shaped filter plate no longer blocks the opening of the collection box, making it easier for gravel particles to enter the collection box.

[0014] Compared with the prior art, this utility model provides a water pump with a self-cleaning function, which has the following beneficial effects:

[0015] 1. This self-cleaning water pump, through its collection component, allows the surface of the connecting rod to contact the surface of the contact block, which in turn moves the arc-shaped filter plate and slider within the annular groove. This opens the collection box, allowing swept-down and shaken-down gravel particles to enter and be collected. When the connecting rod is no longer in contact with the contact block, the slider and arc-shaped filter plate return to their original positions, blocking the opening of the collection box and preventing gravel particles from escaping. The sealing door also facilitates easy cleaning of the gravel particles inside the collection box.

[0016] 2. This self-cleaning water pump, through the set cleaning components, starts the water pump body. Driven by the water flow, the impeller rotates. The fixed rod and slide rod rotate synchronously with the impeller. The brushes on the surface of the fixed rod and slide rod can clean the surface of the filter screen. At the same time, the striking rod rotates, and through the first protrusion, the first protrusion hits the filter screen, causing the filter screen to vibrate and shake off the gravel particles, thus enabling the water pump to self-clean.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a water pump with a self-cleaning function, including a water pump body 1, an inlet pipe 2 fixed to the suction end of the water pump body 1, a collection component 4 for collecting gravel particles and a cleaning component 5 for facilitating cleaning of gravel particles and preventing filter screen 3 from clogging, provided on the surface and inside of the inlet pipe 2, the collection component 4 includes: a collection box 40, the collection box 40 is fixed below the inlet pipe 2 and is interconnected with the inlet pipe 2, a sealing door 41 is installed on the surface of the collection box 40, the collection component 4 also includes an annular groove 43, the annular groove 43 is opened on the inner side of the collection box 40, a slider 42 is slidably connected to the inner wall of the annular groove 43, a spring 44 is fixed to the surface of the slider 42, the end of the spring 44 away from the slider 42 is fixed to the inner wall of the annular groove 43, and the slider 42 is away from the spring An arc-shaped filter plate 45 is fixed to one side of the collection box 40. A notch is opened at the top of the collection box 40. An abutment block 46 is fixed to the surface of the arc-shaped filter plate 45. The surface of the connecting rod 55 abuts against the surface of the abutment block 46, which causes the abutment block 46 to drive the arc-shaped filter plate 45 and the slider 42 to move in the annular groove 43, thereby compressing the spring 44. At this time, the notch of the collection box 40 opens, and the swept-down and shaken-down gravel particles enter the collection box 40. When the connecting rod 55 no longer abuts against the surface of the abutment block 46, the spring 54 is released, which allows the slider 53 and the connecting rod 55 to return to their original positions. At the same time, the spring 44 is released, which drives the slider 42 and the arc-shaped filter plate 45 to return to their original positions, blocking the notch of the collection box 40 and preventing the gravel particles inside from escaping out of the collection box 40. This allows the gravel particles in the water inlet pipe 2 to be collected.

[0023] The cleaning assembly 5 includes a base plate 50, which is fixed to the surface of the filter screen 3. An impeller 51 is rotatably connected to the side of the base plate 50 away from the filter screen 3. A fixing rod 52 is fixed to the surface of the impeller 51. A connecting groove 501 is formed on the surface of the fixing rod 52. A sliding rod 53 is slidably connected to the inner wall of the connecting groove 501. A second spring 54 is fixed to the surface of the sliding rod 53. The end of the second spring 54 away from the sliding rod 53 is fixed to the inner wall of the connecting groove 501. A groove 56 is formed on the surface of the impeller 51. A striking rod 57 is hinged to the inner wall of the groove 56. A third spring 58 is fixed to the surface of the striking rod 57. The end of the third spring 58 away from the striking rod 57 is fixed to the inner wall of the groove 56. A first protrusion 59 is fixed to the side of the striking rod 57 near the filter screen 3. A second protrusion 500 is fixed to the surface of the filter screen 3. Brushes are fixed to the sides of the sliding rod 53 and the fixing rod 52 near the filter screen 3. The first protrusion 59 and the second protrusion 500 are connected to the filter screen 3. Block 2 500 is spherical. A connecting rod 55 is fixed to the surface of the sliding rod 53 away from the spring 2 54. When the water pump body 1 is started, the filter screen 3 can filter the gravel particles in the water. At the same time, driven by the water flow, the impeller 51 rotates. The fixed rod 52 and the sliding rod 53 rotate synchronously with the impeller 51. At this time, the brushes on the surface of the fixed rod 52 and the sliding rod 53 can clean the surface of the filter screen 3 and sweep off the gravel particles adsorbed on the surface of the filter screen 3. At the same time, the striking rod 57 rotates, driving the protrusion 1 59 to rotate. When the protrusion 1 59 contacts the surface of the protrusion 2 500, the striking rod 57 flips and the spring 3 58 is compressed. When the protrusion 1 59 does not contact the surface of the protrusion 2 500, the spring 3 58 is released, which allows the striking rod 57 to drive the protrusion 1 59 to return to its original position. At the same time, the protrusion 1 59 will hit the filter screen 3, causing the filter screen 3 to vibrate and shake off the gravel particles.

[0024] In use, the water pump body 1 is started. The filter screen 3 filters out gravel particles in the water. Simultaneously, the water flow causes the impeller 51 to rotate, which in turn drives the fixed rod 52 and sliding rod 53 to rotate synchronously with the impeller 51. At this time, the brushes on the surfaces of the fixed rod 52 and sliding rod 53 clean the surface of the filter screen 3, sweeping away the gravel particles adsorbed on its surface. Simultaneously, as the impeller 51 rotates, the striking rod 57 rotates synchronously, which in turn drives the protrusion 59 to rotate. When the protrusion 59 and the protrusion... When block 2 500 contacts the surface of block 2 500, the striking rod 57 flips and the spring 3 58 is compressed. When protrusion 1 59 no longer contacts the surface of protrusion 2 500, the spring 3 58 is released, allowing the striking rod 57 to reset protrusion 1 59. Simultaneously, protrusion 1 59 impacts the filter screen 3, causing it to vibrate and dislodge gravel particles, thus achieving self-cleaning of the water pump body 1. At the same time, when the sliding rod 53 rotates, it drives the connecting rod 55 to rotate synchronously. When the surface of the connecting rod 55 contacts the arc-shaped filter plate 45, the connecting rod... Rod 55 drives slide rod 53 into connecting groove 501, spring 54 is compressed, and at the same time, the surface of connecting rod 55 abuts against the surface of contact block 46, which causes contact block 46 to drive arc-shaped filter plate 45 and slider 42 to move in annular groove 43, compressing spring 44. At this time, the notch of collection box 40 opens, and the swept-off and shaken-off gravel particles enter collection box 40. When connecting rod 55 no longer abuts against the surface of contact block 46, spring 54 is released, which allows slide rod 53 to move. When the linkage rod 55 resets, the spring 44 is released, causing the slider 42 and the arc-shaped filter plate 45 to reset, thus blocking the opening of the collection box 40 and preventing the gravel particles inside from escaping. This allows for the collection of gravel particles in the inlet pipe 2, preventing a large amount of gravel particles from remaining in the inlet pipe 2 after prolonged use of the water pump body 1, which would affect its use. When it is necessary to clean the collection box 40 after prolonged use, turn off the water pump body 1 and open the sealing door 41 to clean the inside of the collection box 40.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
