Description

Technical Field

[0001] This application relates to the technical field of pool cleaning, and in particular to a pool cleaning device. Background Technology

[0002] Swimming pools are dedicated spaces for people to engage in swimming activities or competitions. Most swimming pools are built on land and can be categorized into regular swimming pools and heated pools based on water temperature. During use, pools accumulate trash and floating debris, which can breed bacteria, especially in outdoor pools. This debris mixes with the water or adheres to the pool bottom and sidewalls. Furthermore, the waterline area where the pool surface meets the sidewalls is in prolonged contact with this floating debris, resulting in a significant amount of surface contaminants adhering to the waterline on the walls.

[0003] Currently, to reduce the difficulty of manual cleaning, cleaning robots can be used to clean up trash in swimming pools, using scrapers on the machines to scrub the pool walls.

[0004] However, conventional water surface cleaning robots use a rotating silicone brush with a vertical axis to clean the waterline, which can easily lead to an imbalance of force on the cleaning machine, causing it to shake. Insufficient force on the pool wall may also result in poor cleaning effect. Utility Model Content

[0005] To improve the cleaning ability of swimming pools, this application provides a swimming pool cleaning device.

[0006] The swimming pool cleaning equipment provided in this application adopts the following technical solution: A swimming pool cleaning device includes a floating box and a cleaning assembly. The cleaning assembly is disposed on the floating box and includes a cleaning disc, a cleaning shaft, and a brush plate. A plurality of drive propellers are disposed on one vertical sidewall of the floating box. A drive unit for rotating the drive propellers is disposed in the floating box. The cleaning disc is disposed on one side of the vertical sidewall of the floating box adjacent to the drive propellers and is parallel to the vertical sidewall of the floating box. The cleaning shaft is connected to the cleaning disc and one end of the cleaning shaft is horizontally rotatably connected to the floating box. A drive source for rotating the cleaning shaft is disposed in the floating box. The brush plate is connected to the side of the cleaning disc away from the floating box, and cleaning bristles are disposed on the side of the brush plate away from the cleaning disc.

[0007] By employing the above technical solution, when cleaning a swimming pool, a floating box is first placed in the pool and floats on the water surface. A drive unit rotates a propeller, causing the floating box to move within the pool. By adjusting the speed of different propellers, the side of the floating box equipped with the brush plate is kept in contact with the pool wall. Driven by the drive unit, the brush plate rotates, and the cleaning bristles on it clean the waterline area of ​​the pool wall. Because the cleaning bearing is horizontally positioned, the stability of the brush plate is improved during cleaning. Furthermore, the speed difference of the propellers ensures close contact between the brush plate and the pool wall, enhancing the cleaning effect of the device. Through the coordinated operation of the floating box and the cleaning components, the cleaning capability of the swimming pool is significantly improved.

[0008] Optionally, the floating box has a horizontally opened water inlet on one side where the driving propeller is located. The water inlet extends through both opposite sides of the floating box. A slag removal assembly is provided in the water inlet. The slag removal assembly includes a slag removal plate and a rotating connecting ring. Two rotating connecting rings are rotatably sleeved in the water inlet. Several slag removal plates are connected between the two rotating connecting rings. The floating box is provided with a driving component for driving the rotating connecting rings to rotate.

[0009] By adopting the above technical solution, as the floating box moves in the pool, impurities on the water surface enter the inlet. The rotating connecting ring rotates under the drive of the driving component, causing the slag-removing plate to rotate. The slag-removing plate scoops up the impurities floating on the water surface and places them into the slag storage space of the equipment, thus achieving the collection of waste slag. This helps to further improve the cleaning effect on impurities on the pool surface.

[0010] Optionally, several sets of the cleaning components are provided on the same side of the floating box, and the slag removal plate is arranged in a non-planar shape.

[0011] By adopting the above technical solution, since the slag removal plate is non-planar, the water splash generated when the slag removal plate comes into contact with the water surface is buffered during the rotation of the slag removal plate, reducing the impact of the splashes or waves on the stability of the floating box, and making it impossible for the cleaning brush bristles to stick tightly to the pool wall.

[0012] Optionally, the cleaning disc has several grooves along the radial direction on the side near the brush plate, a slider is slidably disposed in the groove, a connecting rod is vertically connected to the slider, a locking block is disposed on the side of the connecting rod near the central axis of the cleaning disc, and several locking slots are disposed on the edge of the brush plate, with each locking slot corresponding to a locking block.

[0013] By adopting the above technical solution, when installing the brush plate, the brush plate is placed on the cleaning disc, and the slider is pushed so that the locking block is embedded in the locking groove on the brush plate, realizing the detachable connection between the brush plate and the cleaning disc, which makes it convenient for operators to install, remove and clean the brush plate.

[0014] Optionally, an elastic element is provided in the slide groove. One end of the elastic element is connected to the inner end wall of the slide groove, and the other end is connected to the slider. In its natural state, the connecting rod is pressed against the edge of the brush plate under the action of the elastic element.

[0015] By adopting the above technical solution, the elastic element ensures that the snap-fit ​​block is always embedded in the snap-fit ​​groove of the brush plate during the cleaning process, thereby improving the structural stability of the connection part.

[0016] Optionally, a backflush assembly is provided in the water inlet. The backflush assembly includes a backflush pump, a connecting hose, a blower pipe, and blower nozzles. The backflush pump is located in the floating box. The two ends of the connecting hose are respectively connected to the backflush pump and the blower pipe. The blower pipe is located in the water inlet and above the rotating connecting ring. Several blower nozzles are connected on the blower pipe and extend downwards towards the slag removal assembly.

[0017] By adopting the above technical solution, during the slag removal process, the backflush pump is started, and the slag removal plate passing through the slag inlet is backflushed through the connecting hose, air pipe and air nozzle, which reduces the possibility of impurities adhering to the slag removal plate.

[0018] Optionally, the floating box is provided with a water pump connected to the water pump. One end of the water pump extends vertically downward to the bottom of the floating box, and the other end extends to the side wall of the floating box where a cleaning disc is provided and is connected to a rinsing nozzle.

[0019] By adopting the above technical solution, the pump draws water from below the pool and sprays it onto the scrubbed pool wall through the rinsing nozzles to wash away residual impurities, which helps to improve the cleaning effect of the device.

[0020] Optionally, the bottom end of the water pumping pipe is connected to a filter cylinder, the bottom end of the water pumping pipe extends into the filter cylinder, and the filter cylinder has a plurality of filter holes.

[0021] By adopting the above technical solution, the filter cartridge filters the water entering the pumping pipe, reducing the possibility of impurities in the pool water clogging the pumping pipe.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The combination of the floatation box and the cleaning components enhances the cleaning ability of the swimming pool; 2. The arrangement of several cleaning components helps to improve the cleaning efficiency and effect on the pool wall, and also increases the contact area between the cleaning components and the pool wall, reducing the possibility of the brush plate lifting off the pool wall under the action of the differential drive propeller. 3. The water pump washes away the impurities remaining on the pool wall, which helps to improve the cleaning effect of the device. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be further described in detail below. Embodiments of this application provide a swimming pool cleaning device that improves the cleaning ability of swimming pools.

[0031] Example 1 Reference Figure 1 and Figure 2 A swimming pool cleaning device includes a floating box 1, a cleaning component 2, a debris removal component 3, and a backflushing component 4. The floating box 1 has a hollow interior and can float on the water surface. Two drive propellers 5 are horizontally rotatably connected to one of the vertical side walls of the floating box 1. The floating box 1 is equipped with a drive source for rotating the drive propellers 5. A water inlet 101 is horizontally opened on the vertical side wall of the floating box 1 where the drive propellers 5 are located, and the water inlet 101 extends through opposite sides of the floating box 1.

[0032] Reference Figure 2 and Figure 3 The slag removal assembly 3 is disposed in the water inlet 101. The slag removal assembly 3 includes slag removal plates 32, rotating connecting rings 33, and mounting shafts 34. Several rotating connecting rings 33 are vertically and parallelly arranged in the water inlet 101. One mounting shaft 34 is provided on each rotating connecting ring 33, and one end of the mounting shaft 34 is fixedly connected to the inner wall of the water inlet 101. Several slag removal plates 32 are fixedly connected between two rotating connecting rings 33 along the radial direction of the rotating connecting rings 33. The floatation box 1 is provided with a drive source (including but not limited to a servo motor) for driving the rotation of the rotating connecting rings 33.

[0033] Reference Figure 2 and Figure 3 The backflush assembly 4 is installed in the water inlet 101. The backflush assembly 4 includes a backflush pump 41, a connecting hose 42, a blower pipe 45, and blower nozzles 46. The backflush pump 41 is mounted on the floating box 1. Both ends of the connecting hose 42 are connected to the blower pipe 45 43 and the output end of the backflush pump 41, respectively. The blower pipe 45 is installed in the water inlet 101, located above the rotating connecting ring 33. The blower pipe 45 is correspondingly and parallel to each of the slag removal assemblies 3. Several blower nozzles 46 are connected to the blower pipe 45, with the opening end of each nozzle tilted downwards towards the corresponding slag removal assembly 3.

[0034] Reference Figure 1 , Figure 4 and Figure 5 The cleaning assembly 2 is mounted on the floating box 1 and includes a cleaning disc 21, a brush plate 22, a cleaning shaft 23, and cleaning bristles 24. The cleaning shaft 23 is rotatably connected to the vertical sidewall of the floating box 1 adjacent to the drive propeller 5. The cleaning disc 21 is fixed and coaxially connected to the end of the cleaning shaft 23 away from the floating box 1. The floating box 1 is equipped with a drive source for rotating the cleaning shaft 23. The brush plate 22 is coaxially mounted on the side of the cleaning disc 21 away from the floating box 1, and several brush plates 22 are located on the same vertical plane. Cleaning bristles 24 are provided on the side of the brush plate 22 away from the cleaning disc 21, and the brush plate 22 is connected to the cleaning disc 21 by a connector.

[0035] Reference Figure 5 The connecting components include a slider 6, a connecting rod 7, a locking block 8, and a connecting spring 9. Several grooves 211 are formed along the radial direction of the side of the cleaning disc 21 away from the floating box 1, and one slider 6 is slidably disposed in each groove 211. The connecting spring 9 is disposed in the groove 211, with one end connected to the inner wall of the groove 211 and the other end connected to the slider 6. In its natural state, the connecting rod 7 is pressed against the edge of the brush plate 22 by the action of the connecting spring 9.

[0036] Reference Figure 5 The connecting rod 7 is vertically and horizontally connected to the slider 6. One locking block 8 is connected to each connecting rod 7 on the side closest to the central axis of the cleaning disc 21. The locking block 8 has an abutment slope 81 on the side away from the cleaning disc 21. Several locking grooves are provided on the edge of the brush plate 22 on the side away from the cleaning disc 21, and each locking groove corresponds to one locking block 8.

[0037] Reference Figure 2 and Figure 1 A water pump 11 is connected to a water pump pipe 10 on the floating tank 1. The bottom end of the water pump pipe 10 extends vertically downward to the bottom of the floating tank 1, and is connected to a filter cylinder 12 with several filter holes 121. The top end of the water pump pipe 10 extends to the side wall of the floating tank 1 where the cleaning component 2 is located and is connected to a rinsing nozzle 13.

[0038] Reference Figure 1 When cleaning the pool, the floating box 1 is placed in the pool, and the drive source drives the drive propeller 5 to rotate. By adjusting the speed of different drive propellers 5, the speed of the drive propeller 5 closer to the cleaning component 2 is lower than that of the drive propeller 5 farther away from the cleaning component 2, so that the brush plate 22 is in close contact with the pool wall and the floating box 1 moves forward. At the same time, the brush plate 22 rotates under the action of the drive source and brushes the waterline part of the pool wall, brushing off the impurities adhering to it.

[0039] Reference Figure 5 When installing the brush plate 22, it is pushed towards the cleaning disc 21, and the edge of the brush plate 22 contacts the abutting inclined surface 81. Under the pushing action, the slider 6 slides away from the center of the cleaning disc 21, and the connecting spring 9 is stretched. When one side of the brush plate 22 is in contact with the cleaning disc 21, the locking block 8 is embedded in the locking groove under the action of the connecting spring 9, realizing a quick and detachable connection between the brush plate 22 and the cleaning disc 21, facilitating the operator's installation, removal, and cleaning of the brush plate 22. The connecting spring 9 improves the structural stability of the connector during the cleaning process.

[0040] Reference Figure 1 and Figure 2 During the cleaning process, the water pump 11 draws water from inside the pool and sprays it onto the freshly washed pool walls through the rinsing nozzles 13, cleaning away any remaining impurities and further improving the cleaning effect of the device. The filter cartridge 12 filters the water entering the water inlet pipe 10, reducing the possibility of impurities clogging the inlet pipe.

[0041] Reference Figure 1-3 As the floating box 1 moves, water and impurities from the pool surface enter the inlet 101. The rotating connecting ring 33 rotates under the drive of the power source, causing the connected slag-removing plate 32 to rotate. The slag-removing plate 32 scoops up the floating impurities and sweeps them into the corresponding collection space (not shown in the attached diagram) for collection, thus improving the pool's cleaning ability. Simultaneously, the backflushing pump 41 starts, backflushing the slag-removing plate 32, which rotates above the slag inlet 312, through the connecting hose 42, connecting manifold 43, connecting branch pipe 44, blowing pipe 45, and blowing nozzle 46, reducing the possibility of impurities adhering to the slag-removing plate 32.

[0042] The implementation principle of the swimming pool cleaning equipment in Embodiment 1 of this application is as follows: When cleaning the swimming pool, the floating box 1 is placed in the pool, the brush plate 22 is pressed against the pool wall, and the floating box 1 moves forward. At the same time, the brush plate 22 rotates and cleans the waterline part of the pool wall. During the cleaning process, the water pump 11 draws water from inside the pool and sprays it onto the freshly cleaned pool wall through the rinsing nozzle 13 to clean up any remaining impurities.

[0043] As the floating box 1 moves, water and impurities on the surface of the pool enter the inlet 101. The slag removal plate 32 rotates, and the slag removal plate 32 picks up and collects the impurities floating on the water surface, which helps to improve the cleaning ability of the pool.

[0044] Example 2 Reference Figure 6 The difference between Example 2 and Example 1 is that the slag removal plate 32 is wavy. Because the slag removal plate 32 is wavy, the water splashes and waves generated when the slag removal plate 32 comes into contact with the water surface are reduced, the possibility of the brush plate 22 separating from the pool wall under the action of waves is reduced, and the structural stability of the device is improved during cleaning.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
