Description

Technical Field

[0001] This invention relates to a novel sealed pool pump. Background Technology

[0002] A pool pump is a water pump used in swimming pools and similar settings. It can be applied in residential areas, schools, swimming pools, fitness centers, bathhouses, and other places requiring a large flow of hot water. It draws pool water into the pump, filters and purifies it, and then returns the treated water to the pool, creating a water circulation system. This effectively keeps the pool water clear and clean, preventing water accumulation at the bottom and a decrease in alkalinity. It also removes impurities, solid particles, organic matter, and bacteria from the pool water, ensuring its quality and cleanliness. Pool pumps come in various types, classified by the number of impellers (single-stage pumps and multi-stage pumps) and by the impeller suction method (single-suction pumps). Pool pumps can be categorized into two types: 1) pumps with two inlets (double-suction pumps); 2) pumps with two outlets (double-inlet pumps); and 3) pumps with two outlets (double-suction pumps). Based on material, they can be classified as plastic pumps, cast iron pumps, copper pumps, stainless steel pumps, etc. The working principle of a pool pump is mainly based on the dynamics of the pump. Driven by a motor, a low-pressure zone is created, drawing pool water into the inlet. Force is then applied to force the water out of the pump, where it is filtered and purified again before returning to the pool. In daily use, pool pumps require frequent inspection and regular cleaning of the sludge basket, keeping the motor clean and the vents clear, and timely replacement of worn shaft seals and other components. In winter, water should be removed from the pump head, the inside and outside of the pump should be cleaned, and the pump should be stored in a dry and well-ventilated indoor environment.

[0003] Currently available pool pumps are characterized by large flow rates, high temperature resistance, simple structure, and filtration functions. However, errors may occur during the manufacturing, assembly, and use of pool pumps, easily leading to leakage problems at connection points. Especially when pumping pool water at high flow rates, the high pressure generated inside the pump can exert significant pressure on the sealing parts. During the pool pump's circulation and filtration process, although the pump has an impurity filtration function, prolonged use can cause severe clogging of the filter screen and increase the internal pressure of the pump body. This not only reduces the efficiency of pool water delivery but also easily damages the pump, shortening its service life. In such cases, the pump needs to be shut down for cleaning. However, frequent opening and closing of the top cover can cause wear at the connection points and increase the complexity of operation, making it impossible to clean while the pool water is circulating, thus causing inconvenience in the use of the pool pump. Summary of the Invention

[0004] To address the technical problem that pool pumps are prone to leakage at the sealing position due to high pressure, this invention provides a pool pump with a novel sealing structure.

[0005] To address the shortcomings of existing technologies, this application employs a combination of a top cover and a transparent cover to install the mesh frame. By improving the structure at the connection between the pump body, the mesh frame, and the transparent cover, and by using sealing rings and gaskets to achieve further compression and sealing, the connection point of the transparent cover is not affected by high pressure and high temperature, thus preventing leakage problems and improving sealing performance. At the same time, it ensures the stable installation of the mesh frame and facilitates the filtration of impurities entering the mesh frame.

[0006] To further address the problems in existing technologies: when the mesh frame filters impurities for an extended period, the guide plate and flow deflector work together to achieve spiral flow of pool water inside the pump body. A rotating scraper cleans the surface of the filter screen, allowing impurities filtered on the mesh frame to settle at the bottom, ensuring the filter screen's efficient filtration function and avoiding impact on the pump's delivery efficiency.

[0007] Furthermore, to address the problems in the existing technology: when the blockage inside the pump body becomes more severe, the high pressure generated causes the sleeve to move, enabling the automatic discharge of impurities and preventing excessive blockage caused by impurities. By discharging some pool water to flush out impurities, the impurities inside the pump body are automatically cleaned, eliminating the need for regular cleaning of the mesh frame. At the same time, it reduces the number of times the top cover is opened, which helps improve the sealing performance at the top cover connection and extends the service life of the pool pump.

[0008] The present invention solves the above-mentioned technical problems through the following technical solutions:

[0009] This invention provides a novel sealed pool pump, the novel sealed pool pump comprising:

[0045] In this technical solution, the injection pipe 307 has a trumpet-shaped structure. The injection pipe 307 is fixedly connected to one side of the pump body 100.

[0046] In this technical solution, a base plate 400 is fixedly connected to the bottom of the outer shell 300.

The inner wall of the outer shell 300 is fixedly connected to the cover 306. The cover 306, the outer shell 300, and the base plate 400 are all provided with interconnected channels 401. The channels 401 are inclinedly distributed below the pump body 100 at the bottom of the base plate 400. The base plate 400 at the bottom of the pump body 100 is inserted through the guide rod 207, and the block 209 at the bottom of the guide rod 207 is fitted and slidably inside the channel 401.

[0047] In this technical solution, the connecting mechanism includes a sealing gasket 402 and a sleeve 403. There are two sealing gaskets 402, which are fixedly connected to the bottom of the spray pipe 307 and the inner wall of the cover 306, respectively. The sleeve 403 is located between the sealing gaskets 402, and the sleeve 403 is movably sleeved with the end of the sewage pipe 205. The end of the sewage pipe 205 is fixedly connected with a connecting sleeve 404, and the connecting sleeve 404 is sealed to the inner wall of the sleeve 403. One side of the sleeve 403 is connected to the inner wall of the cover 306 through a connecting spring 405.

[0048] In this technical solution, the sleeve 403 has a first opening 406 on both sides that fits with the connecting sleeve 404, and the two sealing gaskets 402 have a second opening 407 that is staggered with the first opening 406. One of the second openings 407 is connected to the injection pipe 307, and the other second opening 407 is connected to the channel 401.

[0049] In use, the mesh frame 105 is inserted into the pump body 100, with the top of the mesh frame 105 overlapping the pump body 100. At this time, the square notch on one side of the mesh frame 105 corresponds to the guide plate 107. The transparent cover 101 is installed on the top of the pump body 100, with the sealing lead fitted into the edge of the transparent cover 101, causing the washer 103 to press firmly against the top of the mesh frame 105, thus securing the mesh frame 105. The mesh frame 105 is then connected to the top of the fixed pipe. The top cover 104 is then snapped onto the edge of the pump body 100, and rotated to lock it in place. The inlet pipe 108 is connected to the inlet pipe via the first locking cover 109, and the outlet pipe 3... 10. The pump body 100 is fixedly connected to the outlet pipe via the second locking cover 311. After water is injected into the pump body 100, the motor 302 is started. The motor 302 drives the impeller to rotate inside the impeller housing 305, creating a negative pressure inside the pump body 100. At this time, pool water enters from the inlet pipe 108 and is guided by the guide plate 107 to enter the edge of the pump body 100 from one side. This creates a vortex inside the pump body 100 and is spirally conveyed downwards by the guide plate 201. After impurities are filtered through the filter screen 106 of the mesh frame 105, the pool water enters the impeller housing 305 from the spray pipe 307 and is discharged through the outlet pipe 310, thus realizing the pool water... The water is transported by the pool water inside the pump body 100, which drives the blades 202 to rotate. This causes the blades 202 to drive the crossbar 203 and scraper 204 to rotate synchronously. The scraper 204 rotates on the surface of the filter screen 106 to clean impurities, causing them to settle at the bottom of the screen frame 105 for easy removal later. The pool water delivered from the spray pipe 307 pushes the baffle 308 to rotate, causing it to separate from the end 208. At this time, the elasticity of the return spring 210 pushes the guide rod 207 to move, causing the guide rod 207 to separate the block 209 from the channel 401. When the pool pump is in use, if too many impurities clog the filter screen 106, the water inside the pump body 100 will then... High pressure is generated in the drain pipe 205, which pushes the sleeve 403 to move. The sleeve 403 causes the first opening 406 to align with the second opening 407. At this time, impurities at the bottom of the mesh frame 105 enter the channel 401 with the pool water through the first opening 406 and the second opening 407. The block 209 then separates from the channel 401, allowing the impurities to be automatically discharged. After the impurities are discharged, the internal pressure of the pump body 100 returns to normal. At this time, the elasticity of the connecting spring 405 pushes the sleeve 403 to reset, achieving the sealing of the channel 401. This solves the problem of the pump body 100 working continuously under high pressure and improves the service life of the pool pump.
