Description

Swimming pool cleaning device Technical Field

[0001] The present invention relates to the technical field of swimming pool cleaning equipment, and in particular to a swimming pool cleaning device. Background Art

[0002] Swimming pools generate debris and pollutants such as leaves and gravel during use, requiring regular cleaning of the pool water, bottom, and walls to maintain hygiene. A swimming pool cleaning device is designed to address this need, repeatedly cleaning the bottom and walls and filtering the water.

[0003] The swimming pool cleaning device includes many modules such as drainage module, filtration module, drive module, energy supply module, etc. The layout design of the various modules in the existing swimming pool cleaning device is not scientific and reasonable, resulting in uneven mass distribution. Once it encounters a large slope or a large water flow impact, the swimming pool cleaning device is likely to lose balance and roll over or even overturn, affecting the normal use of the swimming pool cleaning device.

[0004] Summary of the Invention

[0005] In order to solve the defect that the existing swimming pool cleaning device is easy to lose balance, roll over or even overturn, the present invention provides a swimming pool cleaning device.

[0006] The technical solution adopted by the present invention is a swimming pool cleaning device, which includes a drainage module arranged at its upper end and an energy supply module arranged at its lower end. Along the moving direction of the swimming pool cleaning device, the energy supply module and the drainage module are respectively arranged at both ends of the swimming pool cleaning device.

[0007] Compared with the prior art, the present invention has the following beneficial effects: the drainage module and the energy supply module are the two main modules with relatively large weight inside the swimming pool cleaning device. The two heavy modules are respectively arranged at the upper and lower ends and the front and rear ends of the swimming pool cleaning device. Regardless of whether the swimming pool cleaning device is placed flat on the bottom of the swimming pool for cleaning operations, or climbs to the side wall of the swimming pool for cleaning or leaves the swimming pool, the center of gravity of the swimming pool cleaning device can be maintained close to its center, thereby reducing the probability of losing balance and turning over or even overturning when climbing a large slope or encountering a large water flow impact, thereby improving the balance of the swimming pool cleaning device and ensuring the normal use of the swimming pool cleaning device.

[0033] To make the objectives, technical solutions, and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Examples of the embodiments are shown in the accompanying drawings, wherein the same reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0034] In one embodiment, as shown in FIG1 , a swimming pool cleaning device includes a drainage module 2000 and an energy supply module 1000. The drainage module 2000 is disposed at the upper end of the swimming pool cleaning device. The drainage module 2000 draws water from the swimming pool cleaning device and discharges the water through its upper outlet, thereby providing reverse thrust for the swimming pool cleaning device. The energy supply module 1000 is disposed at the lower end of the swimming pool cleaning device, and the functional modules provide energy to the various modules and components within the swimming pool cleaning device. The energy supply module 1000 and the drainage module 2000 are respectively disposed at both ends of the swimming pool cleaning device along its direction of movement, with the end closest to the swimming pool cleaning device's forward direction being the front end of the swimming pool cleaning device and the end away from the swimming pool cleaning device's forward direction being the rear end of the swimming pool cleaning device. The energy supply module 1000 and the drainage module 2000 are respectively disposed at the front and rear ends of the swimming pool cleaning device.

[0035] The pool cleaning device's energy supply module 1000 requires energy storage, and therefore includes high-density, heavy components such as batteries. The drainage module 2000 requires a pump and other components to drain the pool water. The pump needs to generate a high flow rate and pressure to complete the cleaning process, so the pump body is typically made of high-density metal. Therefore, the drainage module 2000 and the energy supply module 1000 are the two main, heavier modules within the pool cleaning device. Positioning these two heavy modules at the upper and lower, and front and rear, ends of the device ensures that the device maintains its center of gravity, whether it's lying flat on the pool floor, climbing up the sidewall, or leaving the pool. This reduces the likelihood of the device losing balance and tipping over or even capsizing when climbing steep slopes or encountering strong currents. This improves the device's balance and ensures its proper operation.

[0036] In one embodiment, the energy supply module 1000 is arranged on the end of the swimming pool cleaning device away from its forward direction, that is, the drainage module 2000 is arranged on the end of the swimming pool cleaning device close to its forward direction. The drainage module 2000 serves as the main power component for generating reverse thrust. Placing it at the end of the swimming pool cleaning device in the forward direction can directly provide power support for movement, better reduce the probability of it overturning or damage when climbing the wall, and improve balance and reliability.

[0037] In one embodiment, the drainage module 2000 includes a pump body, an impeller and a water outlet cover, which are sequentially installed at the first water outlet. A grille is provided on the water outlet cover, and the water outlet cover is detachably installed on the shell. The impeller and the pump body can also be detachably connected. In this way, the user can clean the dirt, such as hair, entangled on the impeller and the water outlet cover by disassembly.

[0038] In one embodiment, the swimming pool cleaning device further includes a driving module 3000 and a filtering module 4000 . The driving module 3000 is disposed below the drainage module 2000 , and the filtering module 4000 is disposed above the energy supply module 1000 .

[0039] Placing the driver module 3000 below the drainage module 2000 allows it to be installed using the base structure provided by the drainage module 2000 without affecting the unobstructed drainage outlet of the drainage module 2000. The driver module 3000 is positioned below the pool cleaning device, allowing it to directly drive the device and the roller brush at its base to clean the pool floor and walls. This reduces transmission distance and ensures more reliable operation. The driver module 3000 and the energy supply module 1000 are both positioned at the bottom of the cleaning device. The closer proximity between the driver module 3000 and the energy supply module 1000 facilitates energy supply from the energy supply module 1000 to the driver module 3000, reducing complex wiring design and improving stability. The filter module 4000 is positioned above the energy supply module 1000, facilitating manual removal of the filter module 4000 from the top of the pool cleaning device for cleaning and maintenance, while avoiding interference with the energy supply module 1000. Each module, by matching its shape, interfaces, and functionality, fits into the gaps between other modules, achieving overall mutual support. The four modules are stacked one on top of the other, making fuller use of space. Compared to a flat layout, this significantly saves space and improves space efficiency while ensuring full functionality.

[0040] In one embodiment, as shown in Figures 2-3, the energy supply module 1000 includes a sealing structure and a battery disposed within the sealing structure. The sealing structure includes a first cover 110, a second cover 120, and a sealing ring 130. The sealing ring 130 is press-fitted between the first cover 110 and the second cover 120. The first cover 110 is formed with a first stopper 111 protruding toward the second cover 120, and the second cover 120 is provided with a first groove that engages with the first stopper 111.

[0041] During use, the first limiting portion 111 on the first cover 110 is snap-fitted to the first groove of the second cover 120, and the sealing ring 130 is press-fitted between the first cover 110 and the second cover 120. The sealing ring 130, the snap-fitting first limiting portion 111, and the first groove can prevent external liquid from entering between the first cover 110 and the second cover 120, thereby achieving a sealing effect. When the first cover 110 or the second cover 120 is about to deform under stress or the effects of heat or cold, the first limiting portion 111 extending into the first groove can transmit a lateral abutting force to the first groove through their snap-fitting, thereby limiting the displacement of the first cover 110 and the second cover 120 in a direction perpendicular to the contact surface between the two, thereby resisting the impending deformation of the first cover 110 and the second cover 120 and preventing the seal from failing. This sealing structure is applied to a pool cleaning device, so that the first cover 110 provided with the first limiting portion 111 and the second cover 120 with the first groove can seal batteries or electronic devices with extremely high protection level requirements, which is conducive to maintaining the long-term sealing of the batteries or electronic devices and ensuring the normal operation of the entire pool cleaning device.

[0042] In one embodiment, an adhesive may be applied between the first cover 110 and the second cover 120. The adhesive may fill the gap between the first cover 110 and the second cover 120, while preventing the first cover 110 and the second cover 120 from deforming and separating under stress and heat and cold, thereby better improving the sealing effect of the sealing structure. The adhesive may be an acrylate adhesive, an epoxy adhesive, or the like. Certain components in the adhesive may change, thereby causing the adhesive to deteriorate and solidify. The deteriorated adhesive may lose its adhesive and sealing effects, while the snap-fitting first limiting portion 111 and the first groove may compensate for the failure of the adhesive. The first limiting portion 111 and the first groove may provide a lateral limiting effect for the sealing structure, thereby preventing the first cover 110 and the second cover 120 from deforming and warping and separating, thereby ensuring the sealing effect of the sealing structure.

[0043] In one embodiment, as shown in FIG7 , the first limiting portion 111 is arranged as a plurality of separated protrusions along the edge of one side of the first cover body 110, and the first groove is set to a shape that matches the first limiting portion 111. Specifically, depending on the difference in force and temperature at different positions, there will be one or more relatively weak parts on the edge of the sealing structure. The multi-segment protrusions of the first limiting portion 111 can be set at these weak parts, which can greatly avoid deformation of these weak parts and prevent the sealing failure of the sealing structure. The cost is low and the sealing effect is better. In other embodiments, the application scenarios of the sealing structure are different, and its weak parts will also be different. Therefore, the position and number of the multi-segment protrusions of the first limiting portion 111 can be personalized.

[0044] In one embodiment, as shown in FIG6 , the first limiting portion 111 is arranged along the edge of one side of the first cover 110 and is in the shape of a closed ring. The first groove is configured as an annular groove that matches the annular first limiting portion 111. The annular first limiting portion 111 can cooperate with the annular first groove to limit the lateral displacement of the sealing structure throughout the entire circle, preventing deformation of the sealing structure throughout the entire circle. This reduces the probability of warping and debonding of the first cover 110 and the second cover 120, and improves the sealing effect. Furthermore, the first limiting portion 111 is provided in multiple circles along the same side of the first cover 110, and the second cover 120 is provided with multiple circles of first grooves that snap-fit ​​with the multiple circles of the first limiting portion 111. The multiple circles of the first limiting portion 111 each provide a lateral force, better limiting the displacement of the first cover 110 and the second cover 120 in a direction perpendicular to their contact surface.

[0045] In one embodiment, as shown in Figures 4-5, the side surface of the first limiting portion 111 in the protruding direction has an abutment surface 111A, which abuts against the side wall of the first groove. The abutment surface 111A and the side wall of the first groove transmit lateral force through the abutment, thereby limiting the displacement of the first cover body 110 and the second cover body 120 in a direction perpendicular to the contact surface between the two.

[0046] In one embodiment, the first limiting portion 111 is further provided with a guide surface 111B inclined toward the abutting surface 111A. The distance between the abutting surface 111A and the guide surface 111B gradually decreases along the protruding direction of the first limiting portion 111. The guide surface 111B can provide a guiding function to assist the first limiting portion 111 to be smoothly aligned and inserted into the first groove.

[0047] In one embodiment, the protruding direction of the first limiting portion 111 is perpendicular to the contact surface of the first cover body 110 and the second cover body 120, so that the force between the first limiting portion 111 and the first groove is mainly the force perpendicular to the contact surface of the first cover body 110 and the second cover body 120, that is, the force provided by the first limiting portion 111 and the first groove to resist the lateral deformation of the first cover body 110 and the second cover body 120 is greater, the probability of warping and deformation of the sealing structure is lower, and the sealing effect is better.

[0048] In one embodiment, the second cover 120 is formed with a second limiting portion 121 that cooperates with the first cover 110, and the first cover 110 is provided with a second groove that engages with the second limiting portion 121. The first limiting portion 111 primarily limits the lateral deformation of the second cover 120, while the second limiting portion 121 primarily limits the lateral deformation of the first cover 110. The first limiting portion 111 and the second limiting portion 121 are arranged in coordination to provide a better limiting effect on the sealing structure, thereby improving the sealing of the sealing structure. In addition, the addition of the second limiting portion 121 can extend the distance that external liquid can flow into the interior of the sealing structure, reduce the probability of liquid flowing into the interior of the sealing structure, and further improve the sealing effect of the sealing structure.

[0049] In one embodiment, the protruding direction of the first limiting portion 111 and the protruding direction of the second limiting portion 121 are roughly parallel, so that when the first cover body 110 and the second cover body 120 are snapped together and installed, the first limiting portion 111 and the second limiting portion 121 can be quickly inserted into the first groove and the second groove, which is convenient for installation and disassembly, and the overall size of the sealing structure is relatively small, the structure is tighter, and the integrity is better.

[0050] In one embodiment, the sealing ring 130 contacts at least two surfaces extending in different directions on the first cover 110 and / or the second cover 120. Compared to a sealing structure in which the sealing ring 130 is merely press-fitted between the surfaces of the upper and lower covers, the sealing ring 130 in this embodiment seals against the first cover 110 and / or the second cover 120 at two locations, thereby increasing the sealing area. The probability of the seal being broken at both locations is low, resulting in better sealing performance. In addition, the two locations of the sealing are located on surfaces extending in different directions on the first cover 110 and / or the second cover 120. If the seal on one surface fails due to deformation of the first cover 110 and / or the second cover 120, the other surface can continue to perform its sealing function, making the sealing structure more reliable.

[0051] In one embodiment, a gap is formed between the first limiting portion 111 and the second limiting portion 121, and the sealing ring 130 is located in the gap. At the same time, the sealing ring 130 is also pressed between the first cover body 110 and the second cover body 120, so that there are abutment portions between the sealing ring 130 and the first limiting portion 111, the first cover body 110, the second limiting portion 121 and the second cover body 120 respectively. At least two of the abutment portions need to be destroyed for liquid to flow through the sealing ring 130 from the outside, so that it is difficult for liquid to enter the interior of the sealing structure at the sealing ring 130, further improving the sealing effect of the sealing structure.

[0052] In one embodiment, the protruding directions of the first limiting portion 111 and the second limiting portion 121 are opposite. This structural setting can avoid mutual interference between the first limiting portion 111 and the second limiting portion 121 during plugging, facilitate the plug-in assembly of the first limiting portion 111 and the first groove, and the second limiting portion 121 and the second groove, and simplify the operation.

[0053] Furthermore, the first limiting portion 111 is arranged along the edge of one side of the first cover 110 and is in the shape of a closed ring, and the second limiting portion 121 is arranged along the edge of one side of the second cover 120 and is in the shape of a closed ring. That is, both the first cover 110 and the second cover 120 have openings, the first limiting portion 111 is arranged along the circumference of the opening of the first cover 110, and the second limiting portion 121 is arranged along the circumference of the opening of the second cover 120. The entire circumference of the edges of the first cover 110 and the second cover 120 can be subjected to a force that resists their own deformation, which reduces the probability of warping and debonding of the first cover 110 and the second cover 120, and improves the sealing effect.

[0054] In one embodiment, a male fastener 112 is provided at the edge of the first cover 110, and a female fastener 122 is provided at the edge of the second cover 120. The male fastener 112 and the female fastener 122 are detachably connected. Specifically, the detachable connection between the male fastener 112 and the female fastener 122 can be a threaded connection, a snap connection, or a magnetic connection. This detachable connection facilitates the removal of the sealing structure and the replacement of the contents of the sealing structure at any time. The male fastener 112 and the female fastener 122 can also be bonded together, which provides a more stable and tighter connection.

[0055] In one embodiment, the first limiting portion 111 is disposed on a side of the second limiting portion 121 away from the middle of the sealing structure. The protruding height of the first limiting portion 111 is greater than the protruding height of the second limiting portion 121, and / or the protruding width of the first limiting portion 111 is greater than the protruding width of the second limiting portion 121. Since the first limiting portion 111 is closer to the outside of the sealing structure than the second limiting portion 121, liquid is more likely to erode the first limiting portion. Therefore, setting the height and width of the first limiting portion 111 larger can better resist lateral deformation of the sealing structure and improve the overall sealing effect of the sealing structure.

[0056] In one embodiment, as shown in Figures 8, 9, and 11, the energy supply module 1000 includes a wire assembly, which includes a base 210, a locking nut 220, and a waterproof cover 230. The base 210 has a mounting hole 211 through which a wiring harness 250 for components such as batteries and circuit boards can pass. The locking nut 220 is threadedly connected to the periphery of the base 210. Specifically, the base 210 has an outer thread, and the inner thread of the locking nut 220 has an inner thread that mates with the outer thread of the base 210. In one embodiment, a sealing ring can be press-fitted between the inner and outer circumferences of the locking nut 220, thereby locking the locking nut 220 to the base 210 and preventing liquid from passing through the threaded connection between the two. The locking nut 220 has a locking portion 221 extending toward the central axis of the mounting hole 211 at one end away from the mounting hole 211. A locking hole is formed at the center of the locking portion 221, which is coaxial with the mounting hole 211. Waterproof cover 230 is made of a flexible waterproof material. It is coaxial with mounting hole 211 and is press-fitted between locking portion 221 and wiring harness 250. The inner diameter of waterproof cover 230 matches that of wiring harness 250, allowing wiring harness 250 to pass through it. The inner wall of waterproof cover 230 abuts the outer wall of wiring harness 250. The locking hole has a diameter that is smaller than or equal to the outer diameter of waterproof cover 230, allowing locking nut 220 to press waterproof cover 230 against wiring harness 250.

[0057] In this embodiment, the wiring harness 250 passes through the mounting hole 211 and the locking hole in sequence, thereby realizing the lead-out of the wiring harness 250; at the same time, the waterproof cover 230 is made of a flexible waterproof material, which is firmly pressed against the outer periphery of the wiring harness 250 under the extrusion deformation of the locking portion 221 of the locking nut 220, ensuring that liquid cannot pass through between the wiring harness 250 and the locking hole; the outlet assembly is fixed to the outer surface of the sealing structure so that the mounting hole 211 is opposite to the outlet hole of the sealing structure, reducing the probability of external liquid entering the sealing structure from the outlet hole and damaging components such as batteries and circuit boards. Compared with the technology of using sealant that is easy to deteriorate and solidify to achieve sealing at the outlet hole, the sealing is completed by mechanical mechanism in this embodiment, which is more reliable and has a better sealing effect.

[0058] In other embodiments, multiple waterproof sleeves 230 can be pressed between the locking portion 221 of the locking nut 220 and the wiring harness 250, so that the locking portion 221, the waterproof sleeves 230 and the wiring harness 250 fit more closely and have a better sealing effect.

[0059] In one embodiment, one end of the waterproof sleeve 230 extends out of the locking portion 221 along the axis of the wiring harness 250, and the other end extends to the periphery of the mounting hole 211. Compared to designs in which the waterproof sleeve 230 partially extends into the locking portion 221, the waterproof sleeve 230 in this embodiment fully extends into the locking portion 221. This allows the locking portion 221 to squeeze the waterproof sleeve 230 over a larger area, resulting in a tighter fit between the waterproof sleeve 230 and the wiring harness 250 and a better sealing effect for the outlet assembly. Furthermore, the end of the waterproof sleeve 230 extends beyond the locking portion 221, extending the length of the waterproof sleeve 230 and providing a wider coverage area for the wiring harness 250. Liquid must first penetrate between the portion of the waterproof sleeve 230 extending out of the locking portion 221 and the wiring harness 250 before reaching the portion of the waterproof sleeve 230 facing the locking portion 221. This prolongs the liquid's penetration path, reduces the likelihood of liquid infiltration, and provides a better sealing effect.

[0060] In one embodiment, one end of waterproof sleeve 230 is positioned between locking portion 221 and wiring harness 250, while the other end extends to the edge of mounting hole 211. Abutting the edge of mounting hole 211, waterproof sleeve 230 restricts movement of waterproof sleeve 230 along the axis of mounting hole 211 toward mounting hole 211, thereby improving stability. Furthermore, waterproof sleeve 230 prevents water that has infiltrated from the threaded connection between the inner periphery of locking nut 220 and the outer periphery of base 210 from further flowing into mounting hole 211, further optimizing the sealing effect of the outlet assembly on the outlet hole of wiring harness 250. Furthermore, the outer diameter of waterproof sleeve 230 gradually increases along its axial direction, with the larger end of waterproof sleeve 230 extending to the edge of mounting hole 211. This change in diameter restricts movement of waterproof sleeve 230 along the axis of mounting hole 211 away from mounting hole 211, further limiting displacement of waterproof sleeve 230, improving the stability of the outlet assembly installation, and providing a more reliable seal.

[0061] In one embodiment, a convex ring 212 is formed on the edge of the mounting hole 211 extending toward the locking portion 221, and an abutting step is formed on the inner wall of the waterproof sleeve 230. The abutting step abuts and cooperates with the convex ring 212. On the one hand, the convex ring 212 can abut against the inner wall of the waterproof sleeve 230 to provide a supporting force for the waterproof sleeve 230, thereby reducing the possibility of the waterproof sleeve 230 being deformed in a direction perpendicular to the axis of the mounting hole 211 after being squeezed, thereby preventing sealing failure.

[0062] In one embodiment, a flange 231 extends horizontally outward from the bottom end of the waterproof cover 230. The flange 231 is located between the inner wall of the base 210 and the raised ring 212. The flange 231 increases the contact area between the waterproof cover 230 and the base 210, reducing the possibility of liquid infiltration, improving the sealing effect, and enhancing the stability of the waterproof cover 230 against the base 210.

[0063] In one embodiment, as shown in Figure 14, the inner surface of waterproof cover 230 is provided with an annular sealing rib 232 protruding toward its axis. Compared to other portions of the inner surface of waterproof cover 230, sealing rib 232 can be more closely attached to the circumference of wiring harness 250, providing a better sealing effect. In other embodiments, sealing rib 232 can be provided in multiple circles to provide multiple lines of defense against liquid infiltration.

[0064] In one embodiment, as shown in Figures 9 and 12-13, the outlet assembly also includes a fastening ring 240 that is sleeved on the waterproof sleeve 230. The fastening ring 240 also extends downward to form a sealing skirt 242. The sealing skirt 242 is tightly sealed against the flange 231, further preventing the waterproof sleeve 230 from moving away from the mounting hole 211 along the axial direction of the mounting hole 211, thereby improving the stability of the installation of the outlet assembly.

[0065] In one embodiment, the outlet assembly also includes a fastening ring 240 that is sleeved on the waterproof sleeve 230. The fastening ring 240 has a plurality of clamping claws 241 arranged at intervals along the circumference. The clamping claws 241 are located between the locking portion 221 and the waterproof sleeve 230. The locking nut 220 squeezes the waterproof sleeve 230 through the clamping claws 241, further improving its extrusion deformation effect on the waterproof sleeve 230. The waterproof sleeve 230 and the wiring harness 250 fit more tightly, the probability of liquid penetrating between the two is lower, and the sealing effect is better.

[0066] In one embodiment, the free ends of the clamping claws 241 are arranged obliquely along the screwing direction of the locking nut 220, so that as the locking nut 220 is screwed to the circumferential side of the base 210, the intervals between adjacent clamping claws 241 are reduced, and the tightening force provided by the locking nut 220 to the waterproof cover 230 through the clamping claws 241 is more evenly distributed in the circumferential direction, thereby avoiding local overload or loosening when the waterproof cover 230 and the wiring harness 250 are fitted, thereby improving the reliability of the seal.

[0067] In one embodiment, the thickness of the free end of the clamping claw 241 increases toward the locking portion 221 , further improving the squeezing deformation effect of the locking nut 220 on the waterproof cover 230 and improving the sealing effect.

[0068] In one embodiment, a fastening ring 240 is press-fitted between the locking portion 221 and the base 210, which can reduce the possibility of movement of the fastening ring 240 and provide a more stable seal. Specifically, as shown in Figures 9, 12-13, the outer surface of the fastening ring 240 protrudes away from its axis to form an annular pressing portion 243. A gap is formed between the lower end of the locking portion 221 and the upper end of the base 210, and the pressing portion 243 is press-fitted into this gap. The pressing portion 243 provides an axial sealing structure for the outlet assembly. The combination of multiple sealing types can provide a more reliable seal.

[0069] In one embodiment, as shown in Figures 10-11, the energy supply module also includes a sealing structure, in which batteries, circuit boards and other necessary components can be sealed. The sealing structure is also provided with the outlet assembly in the above embodiment, and the base 210 of the outlet assembly is provided on the outer wall of the sealing structure. Specifically, the base 210 of the outlet assembly can be sealed and fixed on the outer wall of the sealing structure by welding or other methods. An outlet hole is provided on the sealing structure, and the mounting hole 211 is opposite to the outlet hole. The outlet hole and the outlet assembly form an outlet channel for the wiring harness 250 in the sealing structure. The wiring harness 250 of components such as batteries and circuit boards is led out from the outlet hole and the outlet assembly. At the same time, the outlet assembly seals the outlet hole to prevent liquid from entering the sealing structure.

[0070] In one embodiment, a pool cleaning device includes a sealing structure and a battery encapsulated in the sealing structure. The pool cleaning device also includes the wire outlet assembly of the above embodiment. The base 210 is disposed on the outer wall of the sealing structure. The sealing structure has a wire outlet hole. The mounting hole 211 is opposite the wire outlet hole. The wire outlet hole and the wire outlet assembly form a lead-out channel for the battery wiring harness 250 in the sealing structure, which is more reliable and has a better sealing effect.

[0071] In other embodiments, the outlet assembly is not limited to being used for sealing cables, but can also be applied to any structure that requires sealing.

[0072] In one embodiment, as shown in Figures 1 and 15-18, a swimming pool cleaning device includes a housing 310, a drainage module 2000, and a filtration module 4000 disposed within the housing 310. The housing 310 is provided with a water inlet 311 and a first water outlet. The water inlet 311, the filtration module 4000, the drainage module 2000, and the first water outlet are sequentially connected to form a water flow channel. A partitioning assembly 320 is also disposed within the housing 310. The partitioning assembly 320 constrains the inner cavity of the housing 310 to form a water inlet chamber 324 and a receiving chamber. The water inlet chamber 324 is isolated from the receiving chamber. The filtration module 4000, the water inlet chamber 324, and the drainage module 2000 are sequentially connected. Fluid flows within the water inlet chamber 324 under the action of the drainage module 2000.

[0073] During use, the pool cleaning device is placed in pool water. The pool water to be cleaned flows in through the water inlet 311 of the housing 310, is filtered by the filter module 4000, and flows into the water inlet chamber 324. The pool water in the water inlet chamber 324 is then pumped out by the drainage module 2000 and finally flows out of the pool cleaning device through the first water outlet. In this embodiment, the first water outlet is the mounting hole that connects the drainage module 2000 to the outside.

[0074] In conventional pool cleaning devices, pool water filtered by filter module 4000 tends to escape throughout housing 310. Drain module 2000, acting as the primary power source for pool water circulation, extracts the scattered water from housing 310. However, in the pool cleaning device of this embodiment, when the liquid filtered by filter module 4000 does not flow into the accommodating chamber, the pool water is confined solely to inlet chamber 324. Inlet chamber 324 is formed within housing 310 and has a smaller volume than the housing 310 itself. This reduces the space available for pool water to escape within inlet chamber 324, making it easier to form orderly streamlines compared to within housing 310. This reduces water flow turbulence and fluid resistance, resulting in relatively low energy consumption when drain module 2000 extracts pool water from inlet chamber 324, thereby improving efficiency. Ultimately, given a given power system performance, the device's endurance is significantly improved. When the liquid filtered by the filtration module 4000 flows into the water inlet chamber 324 and the accommodating chamber respectively, the water inlet chamber 324 and the accommodating chamber divide the inner cavity of the swimming pool cleaning device housing 310 into two smaller spaces. The liquid cannot escape between the water inlet chamber 324 and the accommodating chamber, which also reduces the turbulence of the water flow. The energy consumption of the drainage module 2000 when extracting the pool water in the water inlet chamber 324 is also reduced.

[0075] Specifically, the drainage module 2000 includes a pump motor, an impeller, a flow deflector, and a pressure hood. The pump motor provides the driving force, which rotates the impeller. The impeller uses dynamic principles to push water from a low-pressure area to a high-pressure area. The impeller's rotation accelerates and directs the water flow. The flow deflector is installed around the impeller to guide the flow. The pressure hood increases the outlet pressure, allowing the liquid to overcome resistance and gravity and be pumped out smoothly.

[0076] In one embodiment, as shown in Figures 18-20, the filter module 4000 is disposed in the water inlet chamber 324, so that water filtered by the filter module 4000 can directly flow into the water inlet chamber 324. Moreover, installing the filter module 4000 directly in the water inlet chamber 324 can also save space.

[0077] Specifically, the first surface of the partition assembly 320 defines a first opening 321 through which the filter module 4000 communicates with the water inlet 311. The second surface of the partition assembly 320 defines a second opening 322 through which the water inlet chamber 324 communicates with the drainage module 2000.

[0078] The filter module 4000 includes a filter box 341. The wall of the filter box 341 is formed with at least a third opening 342 and a fourth opening 343. The third opening 342 communicates with the first opening 321 and the water inlet 311, while the fourth opening 343 is provided with a filtering structure. This allows water within the filter box 341 to be filtered through the fourth opening 343 before flowing out of the drain module 2000. Fluid enters the pool cleaning device through the water inlet 311 of the housing 310. The fluid flowing into the water inlet 311 passes through the first opening 321 of the partition assembly 320, the third opening 342 of the filter box 341, and then into the filter box 341. After being filtered by the filtering structure of the filter box 341, the fluid flows out of the filter box 341, reaches between the partition assembly 320 and the filter box 341, and is then drawn out through the drain module 2000.

[0079] In this embodiment, liquid filtered by the filtration module 4000 enters the water inlet chamber 324. Driven by the drainage module 2000, the liquid within the water inlet chamber 324 flows out of the pool cleaning device. By dividing the space within the pool cleaning device into the water inlet chamber 324 and the storage chamber, compared to the prior art design in which the drainage module 2000 drives the liquid from the entire pool cleaning device to drain out, the space for liquid to escape is limited, and the liquid primarily moves within the water inlet chamber 324. This reduces water flow resistance, conserves the energy required by the drainage module 2000 to drain water, and improves the endurance of the pool cleaning device.

[0080] Among them, the accommodating chamber can accommodate the energy supply module 1000 and the driving module 3000. The accommodating chamber can protect the energy supply module 1000 and the driving module 3000, reduce the probability of liquid entering the energy supply module 1000 and the driving module 3000 and damaging electronic components such as batteries and motors, and ensure the normal operation of the swimming pool cleaning device.

[0081] In one embodiment, the water inlet chamber can be directly enclosed by a partitioning assembly, and the filter module, the water inlet chamber and the drainage module can be connected in sequence by openings on the partitioning assembly that encloses the water inlet chamber.

[0082] In one embodiment, the partition assembly may include one or more partition plates, which are disposed in the housing of the pool cleaning device, and the cavity in the housing is divided into a water inlet chamber and a receiving chamber by the partition plates.

[0083] In one embodiment, at least one side wall of the filter box is a closed plate structure. When the filter box is installed in place, its side wall plate is connected to the inner wall of the shell, thereby dividing the internal space of the shell into two different chambers, one of which is the aforementioned water inlet chamber.

[0084] In other embodiments, a plurality of accommodating chambers may be provided to respectively accommodate the energy supply module 1000 , the driving module 3000 , etc.

[0085] In one embodiment, the pool cleaning device further includes a drive module 3000, an energy supply module 1000, a housing 310, and a partition assembly 320 disposed within the housing 310. The partition assembly 320 and the housing 310 collectively define a water inlet chamber 324 and a receiving chamber. The drainage module 2000 is in communication with the partition assembly 320, and the drainage module 2000 and the partition assembly 320 collectively enclose the water inlet chamber 324. Specifically, the water inlet chamber 324 includes four side surfaces, a top surface, and a bottom surface. The housing 310 and the partition assembly 320 respectively define the three side surfaces, the top surface, and the bottom surface of the water inlet chamber 324. The fourth side surface of the water inlet chamber 324 is defined by the drainage module 2000.

[0086] Both the driver module 3000 and the power supply module 1000 are housed within a chamber, reducing the likelihood of liquid entering the power supply module 1000 and driver module 3000 and damaging electronic components such as the battery and motor. The filter module 4000 is housed within the water inlet chamber 324, reducing fluid resistance and allowing the drain module 2000 to pump pool water from the chamber 324 with relatively low energy consumption. The maximum spacing between the wall of the filter module 4000 and the facing wall of the partition assembly 320 or the drain module 2000 is less than a millimeter. This reduces the capacity of the water inlet chamber 324 defined by the partition assembly 320, shortening the distance the drain module 2000 must pump pool water. This reduces energy consumption and improves the endurance of the pool cleaning device.

[0087] In this embodiment, the top surface of the water inlet chamber 324 is the outer shell 310, and the bottom surface and three side surfaces are all the dividing components 320. At the same time, the dividing component 320 and the wall of the outer shell 310 also need to be connected and interfered with each other, so that the internal space of the outer shell 310 is divided into two different chambers, the water inlet chamber 324 and the accommodating chamber, through the dividing component 320.

[0088] In other embodiments, other structures may be used to define a water inlet chamber and a receiving chamber in the swimming pool cleaning device to reduce energy consumption.

[0089] In one embodiment, a pool cleaning device includes a housing, a drainage module, and a filtration module, with the drainage module and filtration module disposed within the housing. The housing is provided with a water inlet and a first water outlet, which are sequentially connected to form a water flow channel. The housing also includes a water inlet chamber, in which the filtration module is housed. The sidewalls of the water inlet chamber divide the housing into a first cavity and a second cavity. The water inlet chamber and the water flow channel are both located within and interconnected within the first cavity. The drive module and power supply module are disposed within the second cavity to reduce energy consumption and prevent damage to electronic components.

[0090] In this embodiment, the water inlet chamber is surrounded by the outer shell and a side wall plate, and the side wall plate divides the inner space of the outer shell into a first cavity and a second cavity. The overall structure is simple and convenient.

[0091] In one embodiment, the maximum spacing between the wall of the filter module 4000 and the wall of the partition assembly 320 it faces is less than 35 mm. Specifically, the gap between the filter module 4000 and the inner wall of the partition assembly 320 is less than 35 mm. This limits the range of pool water that can escape from the filter module 4000 and reduces the energy consumption of the drainage module 2000. Furthermore, the maximum spacing between the wall of the filter module 4000 and the drainage module 2000 it faces is less than 35 mm, limiting the distance between the filter module 4000 and the drainage module 2000, shortening the distance the drainage module 2000 must pump pool water, further reducing the drainage module 2000's energy consumption. Given a given power system performance, this can significantly improve the endurance of the pool cleaning device. Furthermore, the distance between the wall of the filter module 4000 and the wall of the partition assembly 320 and / or the drainage module 2000 facing it is less than 30 mm. When the capacity of the filter module 4000 remains constant, the capacity of the water inlet chamber 324 defined by the partition assembly 320 is further reduced, the distance for the drainage module 2000 to pump pool water is further shortened, the energy consumption of the drainage module 2000 is reduced, and the endurance of the swimming pool cleaning device is improved.

[0092] In other embodiments, the filter module can also be provided with multiple filter boxes to improve the filtration efficiency of the swimming pool cleaning device. A handle is provided on the top of the filter box to facilitate manual lifting and moving of the filter box.

[0093] In one embodiment, an annular platform is provided within the water inlet chamber, and a protrusion is provided on the periphery of the filter cartridge that matches the annular platform. When the filter cartridge is inserted into the annular platform, the protrusion abuts the annular platform, and the filter cartridge is installed within the water inlet chamber through the cooperation of the annular platform and the protrusion. In other embodiments, a receiving cavity that matches the shape of the filter cartridge 341 can be provided within the partition assembly 320, so that the filter cartridge 341 can be directly placed within the receiving cavity.

[0094] In one embodiment, the pool cleaning device further includes a drive module 3000 and a power supply module 1000. The drive module 3000 primarily includes electronic components such as a motor and is used to drive the cleaning device to move and the roller brush to rotate. The power supply module 1000 primarily includes components such as a battery and provides energy to the various modules within the cleaning device. The drive module 3000 and the power supply module 1000 are disposed within a housing chamber. Liquid entering the pool cleaning device is primarily discharged through the filter module 4000, the water inlet chamber 324, and the drainage module 2000, with minimal liquid entering the housing chamber. This reduces the possibility of water ingress to the power supply module 1000 and the drive module 3000, potentially damaging the battery, motor, and other electronic components.

[0095] In one embodiment, a fifth opening 323 is further defined on the first surface of the partition assembly 320, and a second water outlet 312 is further defined on the housing 310. The second water outlet 312 communicates with the fifth opening 323 to form a first channel. Thus, after the pool cleaning device is removed from the pool, water in the water inlet chamber 324 can quickly flow out through the first channel, increasing the drainage speed of the pool cleaning device and facilitating subsequent maintenance.

[0096] In one embodiment, an opening and closing mechanism is provided on the second water outlet 312, movable between a first position and a second position. When the opening and closing mechanism is in the first position, the first channel allows water to flow through; when the opening and closing mechanism is in the second position, the first channel blocks water flow, forming a water channel. Thus, when the pool cleaning device is still within the pool, maintaining the opening and closing mechanism in the second position prevents the water inlet chamber 324 from exchanging liquid with the pool through the first channel, which could disrupt the water circulation of the pool cleaning device and waste work. When the pool cleaning device is removed from the pool, the opening and closing mechanism moves from the second position to the first position, opening the first channel to quickly drain the water within the pool cleaning device. Specifically, the opening and closing mechanism can be a pivoting baffle, pressure cover, door panel, sliding door, or lifting gate that seals against the second water outlet 312. It can be opened passively by gravity or actively by a drive mechanism. In other embodiments, the opening and closing mechanism can be located at any position on the fifth opening 323 or the first channel, similarly serving to close and open the first channel.

[0097] In one embodiment, a third water outlet 325 is further included. The third water outlet 325 is located at the lowest point of the center of gravity after the pool cleaning device 324 is lifted. In one embodiment, the third water outlet 325 is located above the rear roller brush. The third water outlet 325 increases the water discharge speed. When the pool cleaning device is lifted, the remaining water in the pool cleaning device will be quickly discharged through the second water outlet 312 and the second water outlet 312.

[0098] The first water outlet 312 and the second water outlet 312 are both provided with an opening and closing mechanism to prevent sewage from flowing into the swimming pool cleaning device when the swimming pool cleaning device is working.

[0099] In one embodiment, the opening and closing mechanism moves between a first position and a second position based on the pool cleaning device's depth information. For example, a water-discharge detection assembly can detect the pool cleaning device's depth information to determine whether the device has exited the pool water, thereby adjusting the opening and closing mechanism's position from the second position to the first position. Furthermore, upon detecting that the device is exiting the pool water, the water-discharge detection assembly can control the device to shut down its pump motor if the user does not manually shut down the device, thereby preventing idling due to grounding and reducing energy waste. The water-discharge detection assembly can include at least one of a Hall effect sensor, a water level sensor, or a power sensor.

[0100] In one embodiment, the water discharge detection component includes a power sensor. When the pool cleaning device is outside the pool water, the power of its pump motor will decrease. The power sensor can detect the power of the pump motor to determine whether the pool cleaning device is discharging water.

[0101] In one embodiment, as shown in FIG17 , the water outflow detection device includes an electrode-type water immersion sensor. The electrode-type water immersion sensor comprises two electrode sheets 351 disposed near the rear end and bottom of the pool cleaning device. When either electrode sheet 351 leaves the water, the passage formed by the two electrode sheets 351 is disconnected, indicating that the pool cleaning device has discharged water. This in turn controls the opening and closing mechanism to move to the first position, thereby opening the first passage and achieving rapid drainage. In other embodiments, the water outflow detection device may also include a thermal-sensitive water immersion sensor, an optical water immersion sensor, or the like.

[0102] In one embodiment, two electrode sheets 351 are arranged on the first cover 110 or the second cover 120 of the energy supply module 1000, that is, on the side of the energy supply module 1000. The electrode-type water immersion sensor formed by the two electrode sheets 351 can also cooperate with the driving module 3000 to realize the stranding detection of the swimming pool cleaning device.

[0103] In one embodiment, the water outlet detection device may further include a Hall sensor or other sensor that can represent the depth information of the swimming pool cleaning device.

[0104] In one embodiment, the fifth opening 323 is disposed at the end of the partition assembly 320 away from the drainage module 2000. The drainage module 2000 can drain water in the vicinity thereof, so that the remaining water is primarily concentrated at the end of the partition assembly 320 away from the drainage module 2000. Therefore, the fifth opening 323 is disposed at the end of the partition assembly 320 away from the drainage module 2000. Furthermore, the fifth opening 323 is disposed at the bottom of the partition assembly 320 to facilitate the rapid drainage of remaining water by gravity, thereby facilitating subsequent cleaning and maintenance of the pool cleaning device.

[0105] In one embodiment, a drive module 3000 includes a driving member and two first driven members. The driving member outputs rotational power and has an output end, which drives and connects to the two first driven members. The two first driven members rotate under the drive of the output end. Thus, a single driving member, via its output end, can drive the two first driven members to rotate. Compared to a transmission method in which two driving members drive two first driven members separately, the drive method of this embodiment is more energy-efficient, balancing the forces on the motor shaft in the driving module 3000 while also achieving maximum transmission efficiency. When the driving module 3000 of this embodiment is applied to a pool cleaning device, the two first driven members serve as the device's moving mechanism and roller brush, respectively. This allows the device to move and the roller brush to roll, completing the cleaning of the pool bottom and walls while also saving energy. Even with a relatively small battery capacity, the pool cleaning device can still maintain excellent battery life, allowing for extended underwater operation and improving the user experience.

[0106] In other embodiments, depending on the application scenario, the drive module 3000 may include three or more first driven members. A single active member can drive three or more first driven members through its output end, further saving energy. Different transmission ratios can be designed between the output end and its different first driven members based on actual needs.

[0107] In one embodiment, the active member includes an output gear 410 and a drive source. The drive source drives the output gear 410 to rotate along its axial direction, and each first follower is separately meshed with the output gear 410. In one embodiment, each first follower is disposed on and meshes with teeth in different circumferential regions of the output gear 410. Each first follower is separately meshed with teeth in different regions, thereby preventing interference between different first follower members. It is understood that one first follower may be a gear with an internal gear ring, with which the output gear 410 meshes, while another first follower may be a gear with an external gear ring, with which the output gear 410 meshes. In other embodiments, each first follower is separately meshed with teeth in different axial regions of the output gear 410. This also prevents interference between multiple first follower members and ensures that multiple first follower members can rotate freely under the drive of the output gear 410. In this case, the number of teeth or diameter of the teeth in different axial regions of the output gear 410 can be set as needed.

[0108] In one embodiment, the output end comprises ring gear units staggered along the axial direction of the output gear 410, with each first follower engaging with one of the ring gear units. Different ring gear units drive different first followers without interfering with each other. By varying the number of teeth and diameter of the ring gear units, the transmission ratio of the output gear 410 to different first followers can be more conveniently adjusted to meet diverse transmission requirements.

[0109] In one embodiment, the drive module further includes a second follower, which is transmission-connected to a first follower. This allows a single active member to directly drive at least two first follower members and indirectly drive a second follower, further saving energy. Furthermore, the drive module includes a pair of second follower members, one of which is transmission-connected to a first follower, and the pair of second follower members are transmission-connected to each other. This allows a single active member to directly drive at least two first follower members and indirectly drive two second follower members, further reducing energy consumption.

[0110] In one embodiment, the drive module further includes a transition gear disposed between the first driven member and the driving member. The transition gear can change the rotational direction of the first driven member and the transmission ratio between the driving member and the first driven member, thus facilitating its application in a wider range of scenarios. Furthermore, the transition gear is also disposed between a pair of second driven members to change the rotational direction of the second driven members and the transmission ratio between the pair of second driven members, further expanding the applicable scenarios of the drive module and facilitating its widespread application.

[0111] In one embodiment, as shown in Figures 21-22, the driving module 3000 includes a driving source, an output gear 410, a walking wheel 420 and a first roller brush gear 430. The driving source drives the output gear 410 to rotate along its axial direction. The output gear 410 is driven and connected to the walking wheel 420 and the first roller brush gear 430 respectively. The walking wheel 420 and the first roller brush gear 430 rotate under the drive of the output gear 410. The walking wheel 420 can drive the swimming pool cleaning device to move, and the first roller brush gear 430 can drive the first roller brush to rotate, so that one output gear 410 can synchronously drive the swimming pool cleaning device. Movement and rotation of the first roller brush. Compared with a driving module that requires two driving sources to respectively drive the movement of the swimming pool cleaning device and the rotation of the first roller brush, the driving module of the swimming pool cleaning device of this embodiment is more energy-saving. When the battery capacity of the swimming pool cleaning device is relatively small, it can still maintain a better endurance and maintain long-term underwater operation, thereby improving user experience. It is equivalent to synchronously driving the first roller brush gear 430 by driving the walking wheel 420, or synchronously driving the walking wheel 420 by driving the first roller brush gear 430. The shaft force of the driving source is balanced while also achieving the maximum transmission efficiency.

[0112] In one embodiment, one side of the output gear 410 is drivingly connected to the travel wheel 420 , and the other side is drivingly connected to the first roller brush gear 430 , thereby avoiding mutual interference between the travel wheel 420 and the first roller brush gear 430 .

[0113] In one embodiment, gears at different positions along the axial direction of the output gear 410 respectively drive the connected travel wheel 420 and the cleaning roller brush, that is, the axial length of the output gear 410 is longer than the axial length of the travel wheel 420 and the first roller brush gear 430. The travel wheel 420 and the first roller brush gear 430 are staggered in the axial direction of the output gear 410, thereby avoiding mutual interference between the travel wheel 420 and the first roller brush gear 430, increasing the distance between the travel wheel 420 and the first roller brush gear 430, reducing the difficulty of installation, and facilitating the later separate maintenance or replacement of the travel wheel 420 or the first roller brush gear 430.

[0114] In one embodiment, two gear ring units are staggered along the axial direction of the output gear 410, and the traveling wheel 420 and the first roller brush gear 430 are respectively engaged with one of the gear ring units. Different gear ring units drive the traveling wheel 420 and the first roller brush gear 430 respectively, and the transmission of the two does not affect each other. By changing the number of teeth, diameter, etc. of different gear ring units, the transmission ratio of the output gear 410 to the traveling wheel 420 and the first roller brush gear 430 can be more conveniently changed to meet different transmission requirements.

[0115] In one embodiment, a first inner gear ring is provided on the inner side of the travel wheel 420, which meshes with the output gear 410. The first roller brush gear 430 meshes with the output gear 410, so that the output gear 410 can drive the travel wheel 420 to rotate in the same direction. At the same time, the output gear 410 can also drive the first roller brush gear 430 to rotate in the opposite direction. Thus, a single drive source can simultaneously drive the movement of the pool cleaning device and the rotation of the first roller brush, saving energy, improving the endurance of the pool cleaning device, and enhancing the user experience. In addition, the drive module structure of the pool cleaning device of this embodiment is more concise, simplifying the transmission method and reducing production costs. The drive module is integrated, eliminating the need for two independent drive sources and output gear 410, making the overall structure more compact and occupying less space inside the pool cleaning device, allowing for the installation of more other functional modules.

[0116] In one embodiment, the transmission ratio of the output gear 410 to the traveling wheel 420 is greater than the transmission ratio of the output gear 410 to the first roller brush gear 430. The transmission ratio refers to the ratio of the rotational speed of the input gear to the rotational speed of the output gear 410, that is, the ratio of the rotational speed of the output gear 410 to the rotational speed of the traveling wheel 420 is greater than the ratio of the rotational speed of the output gear 410 to the rotational speed of the first roller brush gear 430. That is, under the transmission of the output gear 410, the rotational speed of the first roller brush gear 430 is greater than that of the traveling wheel 420. Therefore, when the traveling wheel 420 drives the swimming pool cleaning device to move at the required moving speed, the faster rotational speed of the first roller brush gear 430 can drive the first roller brush to repeatedly stir the dirt on the bottom and wall of the pool until the dirt falls off, thereby improving the cleaning force and cleaning efficiency of the first roller brush.

[0117] In one embodiment, the drive module of the pool cleaning device further includes a first transition gear 411, which meshes with the output gear 410, the first transition gear 411, and the first roller brush gear 430 in sequence. The first transition gear 411 can change the rolling direction of the first roller brush gear 430, causing it to rotate in the same direction as the travel wheel 420. This means that the rotation direction of the first roller brush is the same as the forward movement of the pool cleaning device. Consequently, dirt dislodged by the first roller brush is pushed toward the water inlet at the lower center of the pool cleaning device, where it is drawn in and collected by a trash filter connected to the water inlet, thereby improving the cleaning efficiency of the pool cleaning device. Furthermore, the first transition gear 411 can also change the transmission ratio between the output gear 410 and the first roller brush gear 430, thereby varying the rotation speed of the first roller brush. This allows for tailored selection of roller brush speeds for pools with varying dirt types and surface structures, resulting in improved cleaning results and efficiency.

[0118] In one embodiment, the drive module of the pool cleaning device includes multiple first transition gears 411. These first transition gears 411 are positioned adjacent to each other, meshing with each other. The first and last first transition gears 411 respectively mesh with the output gear 410 and the first roller brush gear 430. Each first transition gear 411 can independently vary its transmission ratio. Multiple first transition gears 411 allow for a wider range of transmission ratio variations, providing greater flexibility and meeting diverse cleaning needs.

[0119] In one embodiment, the number of first transition gears 411 is an even number. At this time, the rotation direction of the first roller brush gear 430 is opposite to that of the output gear 410, that is, the rotation direction of the first roller brush is opposite to the forward direction of the swimming pool cleaning device. On the one hand, this setting can use the reaction force brought by the robot's forward movement to help push the dirt, and the dirt is easier to peel off from the bottom and wall of the pool, reducing the working intensity and energy consumption of the first roller brush itself. On the other hand, the first roller brush can push away the garbage on the bottom and wall of the pool after stirring it down, reducing its obstruction to the movement of the swimming pool cleaning device.

[0120] In one embodiment, the driving module of the pool cleaning device further includes a track 423 and a driven wheel 421. The track 423 is tensioned on the running wheel 420 and the driven wheel 421, so that the driven wheel 421 can rotate synchronously with the running wheel 420 and drive the pool cleaning device to move synchronously with the running wheel 420.

[0121] In one embodiment, the drive module of the pool cleaning device further includes a second roller brush gear 431. The driven wheel 421 is driven and connected to the second roller brush gear 431. The output gear 410 drives the second roller brush gear 431 to rotate via the spacing between the running wheel 420 and the driven wheel 421. The second roller brush gear 431 drives the second roller brush to rotate, thereby improving the energy saving and cleaning effect of the pool cleaning device. Specifically, the driven wheel 421 is coaxially fixedly connected to the concentric wheel 422, and the second roller brush gear 431 meshes with the concentric wheel 422. The second roller brush gear 431 is used to drive the second roller brush to rotate, thereby driving the driven wheel 421 to drive the concentric wheel 422 to rotate synchronously, and then the concentric wheel 422 drives the second roller brush gear 431 to rotate. The second roller brush gear 431 drives the second roller brush to rotate, stirring up garbage from the bottom and walls of the swimming pool, further improving the cleaning ability and cleaning efficiency of the pool cleaning device. The driven wheel 421 and the walking wheel 420 jointly drive the swimming pool cleaning device to move, while the first roller and the second roller jointly clean the dirt on the bottom and wall of the swimming pool. The movement of the four components is synchronously driven by a driving source, which further saves energy consumption, ensures the endurance of the swimming pool cleaning device, and improves the user experience.

[0122] In one embodiment, a second transition gear 412 is further included, and the concentric wheel 422, the second transition gear 412, and the second roller brush gear 431 mesh in sequence. The second transition gear 412 also functions to change the rotational direction of the second roller brush gear 431, aligning the rotational direction of the second roller brush with the forward direction of the driven wheel 421. This allows the second roller brush to remove debris from the pool bottom and walls after stirring it down, reducing obstruction to the movement of the pool cleaning device. Furthermore, the second transition gear 412 can also change the transmission ratio between the concentric wheel 422 and the second roller brush gear 431, thereby varying the rotational speed of the second roller brush to adapt to varying pool dirt and improve its cleaning effectiveness.

[0123] In other embodiments, multiple second transition gears 412 may be provided, with each adjacent second transition gear 412 meshing with the adjacent second transition gears 412. The first and last second transition gears 412 mesh with the concentric wheel 422 and the second brush gear 431, respectively. Multiple second transition gears 412 allow for more flexible transmission ratios between the second driven gear and the second brush gear 431, meeting diverse cleaning needs. When the number of second transition gears 412 is odd, the second brush rotates in the same direction as the driven wheel 421, stirring up debris from the pool bottom and walls and then pushing it away. When the number of second transition gears 412 is even, the second brush rotates in the opposite direction of the driven wheel 421. This allows the debris stirred up by the second brush to be pushed toward the water inlet at the bottom center of the pool cleaning device, where it is drawn in and collected by a trash filter connected to the water inlet, improving the cleaning efficiency of the pool cleaning device.

[0124] In one embodiment, the drive module of the pool cleaning device further includes a driven wheel, a second roller brush gear, and a track. The track is tensioned on the travel wheel and the driven wheel, allowing the driven wheel to rotate synchronously with the travel wheel and drive the pool cleaning device to move synchronously with the travel wheel. A second inner ring gear is provided on the inner side of the driven wheel, with the second roller brush gear meshing with the second inner ring gear. The second roller brush gear is used to drive the second roller brush to rotate. The concentric wheel can drive the second roller brush gear to rotate synchronously via its second inner ring gear, and the second roller brush gear then drives the second roller brush to rotate, stirring up garbage from the bottom and walls of the pool, further improving the cleaning ability and efficiency of the pool cleaning device. In this embodiment, no concentric wheel is required, resulting in a simpler overall structure, lower cost, more compact structure, and less space occupancy. In other embodiments, the second roller brush gear and the second inner ring gear can also be meshed and driven by a third transition gear. The number of third transition gears can be odd or even.

[0125] In one embodiment, the outer periphery of the traveling wheel 420 and the driven wheel 421 are both provided with an outer gear ring, and the inner surface of the track 423 is provided with a plurality of first belt teeth matching the outer gear ring. When the track 423 is tensioned on the traveling wheel 420 and the driven wheel 421, the first belt teeth are respectively engaged with the outer gear rings on the outer periphery of the traveling wheel 420 and the driven wheel 421, so that the belt can be firmly tensioned on the traveling wheel 420 and the driven wheel 421, and the traveling wheel 420 can more reliably drive the driven wheel 421 to rotate synchronously, ensuring that the swimming pool cleaning machine device can move stably.

[0126] In one embodiment, the outer surface of the track 423 is further provided with a plurality of second teeth 424. The second teeth 424 enable the track 423 to more securely grip the bottom and walls of the swimming pool, thereby improving the grip and wall-climbing ability of the swimming pool cleaning device, and further ensuring that the swimming pool cleaning machine device can move stably.

[0127] In one embodiment, the pool cleaning device includes a pair of drive modules, one disposed on each side of the main body. The pair of drive sources respectively drive a pair of output gears 410 and a pair of driven wheels 421 to rotate. When the pair of output gears 410 move at the same speed and in the same direction, the pool cleaning device can move forward or backward. When the pair of output gears 410 move at different speeds or in opposite directions, the pool cleaning device can turn.

[0128] In one embodiment, the pool cleaning device further includes two roller brushes, namely a first roller brush and a second roller brush. The output gear 410 drives the first roller brush gear 430 to rotate, and the first roller brush gear 430 drives the first roller brush to rotate. The output gear 410 drives the second roller brush gear 431 to rotate via the gap between the running wheel 420 and the driven wheel 421, and the second roller brush gear 431 drives the second roller brush to rotate. This means that the first roller brush is not driven by the running wheel 420, and the driving force of the first roller brush is transmitted more directly and simply, reducing power conversion between multiple mechanisms and improving transmission efficiency.

[0129] In one embodiment, as shown in Figures 23-24, the filter module 4000 includes a filter cartridge 341 and a second filter structure 510. At least a portion of the wall of the filter cartridge 341 is formed as a filter structure, which is formed into a fourth opening 343. The drainage module 2000 is provided with a drain outlet, which is fluidically connected to the drain outlet, forming a second channel. The second filter structure 510 is detachably mounted on the second channel. Specifically, the second filter structure 510 utilizes an irregular porous membrane or mesh structure to achieve a fine filtration effect that allows water to flow through while blocking impurities. Examples of the filter structure include an activated carbon filter 510, a sand filter 510, a paper filter 510, a filter screen, and the like. After being filtered by the filter cartridge 341 and discharged from the filter structure, the water enters the second channel, undergoes secondary filtration by the second filter structure 510 within the second channel, and is then discharged from the drain outlet of the drainage module 2000.

[0130] The filter cartridge 341 and the second filter structure 510 form a two-stage filtration structure for the pool cleaning device. If the filter cartridge 341's cleanliness isn't sufficient, the second filter structure 510 can be used in conjunction with the second filter structure, improving the pool cleaning device's efficiency and effectiveness. The second filter structure 510 is detachably mounted on the second channel, allowing users to choose whether to install the second filter structure 510 for secondary filtration based on the actual pool water conditions, providing high flexibility. Furthermore, the detachable second filter structure 510 facilitates timely cleaning and replacement if it becomes clogged. The second filter structure 510 can be removed by plugging and unplugging.

[0131] In other embodiments, the second channel includes at least two passages, each of which has both an open and closed state. The second filter structure is located in one of the passages. By varying the open and closed states of different passages, the water flow path is selected. When the passage containing the second filter structure is open and the other passages are closed, the second filter structure participates in filtering the pool water, improving the cleaning efficiency and effectiveness of the pool cleaning device. When the pool water quality is good, the passage containing the second filter structure can be closed, leaving the other passages open, allowing only the filter cartridge to filter the pool water, resulting in smoother water flow and energy savings.

[0132] In one embodiment, as shown in Figures 1, 16, and 20, the pool cleaning device further comprises a housing 310 having a water inlet 311 at the bottom thereof, and a filter module 4000 disposed within the housing 310. The filter module 4000 is disposed at an end of the pool cleaning device away from the forward movement of the device. The filter module 4000 includes a filter cartridge 341. A third opening 342 is disposed at the bottom of the filter cartridge 341 near the forward movement of the device. The water inlet 311 is in fluid communication with the third opening 342, forming a third channel 520.

[0133] Pool water enters the filter box 341 through the third channel 520. The third opening 342 is located near the forward direction of the pool cleaning device, facilitating the relative water flow generated by the forward movement of the cleaning device and the dirt removed by the roller brush to quickly enter the filter box 341, thereby optimizing the filtration efficiency of the pool cleaning device and improving the cleaning performance of the pool cleaning device.

[0134] In one embodiment, the end of the third channel 520 near the water inlet 311 is angled toward the forward direction of the pool cleaning device. This facilitates smooth reception of the water flow generated by the forward movement of the cleaning device and dirt removed by the roller brush through the water inlet 311. This allows the pool water to more quickly and fully enter the filter cartridge 341, achieving filtration. The angle between the third channel 520 and the horizontal plane is 50-80 degrees. When the pool water enters the filter cartridge 341 at this angle, heavier dust and dirt in the pool water can be deposited at the bottom of the filter cartridge 341 due to its weight, reducing the burden on the filter structure of the filter cartridge 341, extending the cleaning cycle of the filter cartridge 341, and improving the filtration efficiency of the pool cleaning device.

[0135] In one embodiment, the angle between the third channel 520 and the horizontal plane is 65-75 degrees. When the third channel 520 and the horizontal plane are at this angle, dust and dirt in the pool water can be deposited on the bottom of the filter box 341 with a greater probability.

[0136] In one embodiment, the end of the third channel 520 close to the water inlet 311 is trumpet-shaped, which can expand the cross-sectional area of ​​the water inlet 311, reduce the flow rate of the pool water, and play a role in draining the entry of the pool water, so as to facilitate the slow entry of the pool water into the box.
