Description

Technical Field

[0001] This utility model relates to the technical field of swimming pool cleaning tools, specifically to a swimming pool cleaning device. Background Technology

[0002] Pool cleaning equipment, such as pool robots, is a smart device used for cleaning and maintaining swimming pools. Typically driven by an electric motor, it uses an impeller to generate water flow, propelling the robot within the pool. It can perform comprehensive cleaning of the pool bottom, walls, and waterline, effectively removing sand, leaves, dirt, and other debris. Some high-end pool robots are also equipped with brushless motors, offering advantages such as high efficiency, low noise, and long lifespan. The pool robot has a dust chamber inside, which draws water from the pool through an intake port. The water is filtered through a built-in filter to remove impurities, dirt, and dust, and then the filtered water is discharged back into the pool, thus achieving the purpose of cleaning the pool. Due to the relatively heavy weight of pool robots, when the robot is horizontally lifted out of the water, it needs to overcome a significant backlash from the water, making operation somewhat strenuous and inconvenient for users.

The first cavity is located at the front end of the dust box cavity, and the second cavity is located at the rear end of the dust box cavity. The battery assembly is disposed in the second cavity, and the second cavity is adapted to communicate with the outside.

[0009] Optionally, the battery assembly is spaced apart from each cavity wall of the second cavity, such that the battery assembly is located in the middle of the second cavity.

[0010] Optionally, the battery assembly is provided with a first positioning part and a second positioning part on its periphery, and the second cavity is provided with a first mating part that cooperates with the first positioning part and a second mating part that cooperates with the second positioning part;

[0011] The first positioning part and the first mating part are positioned and engaged to restrict the movement of the battery assembly relative to the second cavity in the front-rear direction of the device body; the second positioning part and the second mating part are locked together to lock the battery assembly in the second cavity.

[0014] The battery assembly also includes multiple connectors, which are inserted one-to-one into the positioning holes and the positioning posts to connect and fix the battery assembly and the second cavity.

[0015] Optionally, the battery assembly includes a battery casing and a battery pack disposed within the battery casing;

[0016] The battery casing includes a first casing and a second casing connected to each other, and a sealing ring disposed between the first casing and the second casing.

[0020] The technical solution provided by this utility model has the following beneficial effects:

[0021] This utility model provides a swimming pool cleaning device, comprising a main body, a water pump, a dust box chamber, and a battery assembly. The dust box chamber is located in the middle of the main body and is used to store the pool debris sucked up during the cleaning process. The battery assembly provides the electrical energy required for the operation of the main body. The water pump is electrically connected to the battery assembly and provides the suction power required to pump out the debris. Because the battery assembly is relatively heavy, it is positioned behind the dust box chamber, at the rear of the main body, thus shifting the center of gravity of the entire swimming pool cleaning device further back. When the cleaning device floats or climbs, the rearward shift of the center of gravity allows for a better upward tilt at the front, making it easier to lift the front of the main body when climbing pool walls or steps, resulting in smoother climbing. Furthermore, when floating upwards, the front of the main body is more likely to emerge from the water first. This allows the user to better engage the front of the main body when retrieving the cleaning device, enabling it to leave the water in a more lateral position, thus making operation easier.

[0036] This utility model provides a swimming pool cleaning device 100. Specifically, please refer to... Figures 1 to 2 In this embodiment, the pool cleaning device 100 includes a device body 1, a water pump 5, a dust box chamber 2, and a battery assembly 3 disposed on the device body 1. The water pump 5, the dust box chamber 2, and the battery assembly 3 are arranged sequentially from front to back along the device body 1, wherein the dust box chamber 2 is located in the middle of the device body 1, and the battery assembly 3 is located in the rear of the device body 1.

[0037] In this embodiment, the dust box chamber 2 is used to store the pool debris sucked in during the cleaning process, the battery assembly 3 is used to provide the electrical energy required for the operation of the main body 1, and the water pump 5 is electrically connected to the battery assembly 3 to provide the suction power required to suck up the debris. Since the battery assembly 3 is relatively heavy, it is positioned behind the dust box chamber 2, at the rear end of the main body 1, making the center of gravity of the entire pool cleaning device 100 more rearward. When the pool cleaning device 100 floats upward or climbs, because its center of gravity is further rearward, the pool cleaning device 100 can better exhibit an upward tilt at the front end. This makes it easier to lift the front end of the main body 1 when climbing pool walls or steps, resulting in smoother climbing. Furthermore, when floating upward, the front end of the main body 1 is more likely to emerge from the water first. This allows the user to better engage the front end of the main body 1 when removing the pool cleaning device 100, and enables the pool cleaning device 100 to leave the water in a lateral position, making operation easier.

[0038] Among them, combined Figure 1 As shown, the pool cleaning device 100 can be configured as a pool robot. The forward direction of the pool cleaning device 100 is in front of the device body 1, and the backward direction of the pool cleaning device 100 is behind the device body 1. Unless otherwise specified, all descriptions of directions in this utility model shall be based on this.

[0039] Furthermore, the pool cleaning equipment 100 also includes a walking mechanism and two cleaning rollers 4, which are located at the front and rear ends of the main body 1, respectively. The walking mechanism is designed with a track structure, providing better anti-slip performance. Both ends of each cleaning roller 4 are coaxially connected to the drive wheels of the track structure, allowing the two cleaning rollers 4 to rotate synchronously during the movement of the pool cleaning equipment 100, thus contacting and rubbing against the surface to be cleaned. This eliminates the need for a separate drive component to rotate the cleaning rollers 4, saving costs.

[0040] Preferably, combined with Figure 2 As shown, on the orthographic projection along the vertical direction of the main body 1, the projection of the battery assembly 3 and the projection of the cleaning roller brush 4 at the rear end overlap at least partially, so that at least part of the weight of the battery assembly 3 can be pressed against the cleaning roller brush 4 at the rear end, making the contact between the cleaning roller brush 4 at the rear end and the surface to be cleaned closer, and the cleaning effect is better.

[0041] More preferably, combined with Figure 2As shown, in the orthographic projection along the front-rear direction of the main body 1, the projection of the battery assembly 3 and the projection of the cleaning roller brush 4 at the rear end are positioned opposite each other in the vertical direction, that is, the battery assembly 3 is positioned above the cleaning roller brush 4 at the rear end. This ensures that the battery assembly 3 is located in front of and above the cleaning roller brush 4, preventing the battery assembly 3 from being too far back and keeping its center of gravity in front of the cleaning roller brush 4. This prevents the pool cleaning equipment 100 from easily tipping backward when the front end is tilted up, as the center of gravity of the battery assembly 3 would shift to the rear of the cleaning roller brush 4.

[0042] It is understandable that the dust box chamber 2 can be an independent cavity structure that can be detachably installed inside the main body 1 of the equipment, so that the dust box chamber 2 can be removed from the main body 1 of the equipment for cleaning and maintenance.

[0043] Of course, the dust box cavity 2 can also be integrated with the main body 1. The cavity wall of the dust box cavity 2 is directly formed by the internal partition of the main body 1, which reduces the space occupied by the wall thickness of the dust box cavity 2 itself, making the dust box cavity 2 occupy less space in the main body 1.

[0044] Specifically, such as Figure 2 As shown, the main body 1 of the device includes a shell 11 and multiple partitions 12 disposed within the shell 11. The partitions 12 are connected in sequence and together with the shell 11 enclose a dust box cavity 2. The dust box cavity 2 is generally square in shape, and the dust box cavity 2 divides the shell 11 into a first cavity 13 and a second cavity 14 along the front-to-back direction. The suction port is located at the bottom of the dust box cavity 2 to be closer to the surface to be cleaned. The first cavity 13 is located at the front end of the dust box cavity 2, and the first cavity 13 is suitable for installing drive components such as a pump. The second cavity 14 is located at the rear end of the dust box cavity 2, and the battery assembly 3 is disposed within the second cavity 14, which is suitable for communicating with the outside. The drive component and battery assembly 3 are separated by the dust box cavity 2, so that the drive component is better positioned at the front end of the main body 1 and the battery assembly 3 is better positioned at the rear end of the main body 1. This avoids the front end of the main body 1 being too light, which would make it difficult for the front cleaning roller brush 4 to come into contact with the surface to be cleaned. At the same time, it can also ensure that the pool cleaning equipment 100 can climb and float more easily.

[0045] Preferably, combined with Figure 2 and Figure 4As shown, the battery assembly 3 and the walls of each cavity in the second cavity 14 are spaced apart, so that the battery assembly 3 is located in the middle of the second cavity 14. Since the pool cleaning equipment 100 needs to draw water from the pool into the dust box cavity 2 when operating in water, and after filtering and retaining the dirt in the dust box cavity 2, discharge the clean water into the pool, the outer casing 11 is connected to the pool. When the pool cleaning equipment 100 is in water, water enters the second cavity 14, and at this time, the water surrounds the battery assembly 3, which can help dissipate heat from the battery assembly 3.

[0046] Of course, the battery assembly 3 needs to be securely fixed within the second cavity 14 to prevent displacement of the battery assembly 3, which would affect the center of gravity of the entire pool cleaning equipment 100. Specifically, in conjunction with Figures 3 to 5 As shown, a first positioning part 32 and a second positioning part 33 are provided on the periphery of the battery assembly 3. The second cavity 14 has a first mating part 15 that cooperates with the first positioning part 32 and a second mating part 16 that cooperates with the second positioning part 33. The first positioning part 32 and the first mating part 15 are positioned together to restrict the movement of the battery assembly 3 relative to the second cavity 14 along the front-rear direction of the device body 1, thus initially limiting the relative position of the battery assembly 3 within the second cavity 14. The second positioning part 33 and the second mating part 16 are locked together to lock the battery assembly 3 within the second cavity 14, further securing the battery assembly 3 completely within the second cavity 14 and better ensuring that the battery assembly 3 will not shift.

[0047] Preferably, such as Figure 5 As shown, the first positioning part 32 includes multiple limiting ribs 321 protruding from the bottom of the battery assembly 3. Each limiting rib 321 extends along the left-right direction of the device body 1 and is plate-shaped. The first mating part 15 includes multiple limiting slots 151 disposed in the second cavity 14, and preferably, each limiting slot 151 protrudes from the inner side of the bottom wall of the outer shell 11. Each limiting slot 151 is through-type along the left-right direction of the device body 1, so that the multiple limiting ribs 321 can be correspondingly engaged in the multiple limiting slots 151. The limiting slots 151 restrict the movement of the limiting ribs 321 in the front-back direction, thereby restricting the movement of the entire battery assembly 3 relative to the device body 1 in the front-back direction.

[0048] More preferably, combined with Figure 5 and Figure 7As shown, the second positioning part 33 includes multiple positioning protrusions 331 disposed on the peripheral side of the battery assembly 3, and each positioning protrusion 331 is provided with a positioning hole that runs through the vertical direction of the device body 1. The second mating part 16 includes multiple positioning posts 161 protruding into the second cavity 14. Each positioning post 161 extends vertically, and the multiple positioning posts 161 are correspondingly inserted into the multiple positioning holes. The battery assembly 3 also includes multiple connectors, which are correspondingly inserted into the positioning holes and positioning posts 161 to connect and fix the battery assembly 3 and the second cavity 14. The connectors can be screws or bolts, etc., which lock the positioning holes and positioning posts 161 in place, so that the battery assembly 3 can be more securely fixed in the second cavity 14 and better ensure the position of the battery assembly 3.

[0049] While ensuring the reliable fixation of the battery assembly 3 within the second cavity 14, it is also necessary to guarantee the airtightness of the battery assembly 3 to prevent water from entering and damaging it. This is achieved by combining... Figures 5 to 7 As shown, the battery assembly 3 includes a battery casing 31 and a battery pack 34 disposed within the battery casing 31, which encloses the battery pack 34. The battery casing 31 includes a first casing 311 and a second casing 312 connected together, and a sealing ring 35 disposed between the first casing 311 and the second casing 312. The first casing 311 is groove-shaped to form a cavity for placing the battery pack 34, and the second casing 312 covers the opening of the first casing 311, thus closing the opening of the first casing 311. Specifically, the first casing 311 and the second casing 312 are detachably connected, so that the second casing 312 can be removed from the first casing 311 to facilitate the placement of the battery pack 34. The second housing 312 is provided with hooks, and the first housing 311 has buckles at the edge of its groove. Multiple hooks and buckles can be provided, and they are interlocked one-to-one to lock the second housing 312 onto the first housing 311. Furthermore, both the first housing 311 and the second housing 312 have multiple mounting holes. Multiple screws or bolts are inserted into these mounting holes to completely lock the first housing 311 and the second housing 312 together, making the connection tighter and more secure, thus preventing water from entering the first housing 311 and the second housing 312.

[0050] Moreover, combined Figure 6 and Figure 7As shown, two annular flanges 3111 protrude outward from the groove of the first housing 311. The two annular flanges 3111 are nested together, with a gap between them. Two annular ribs 3121 protrude from the side of the second housing 312 facing the first housing 311. The two annular ribs 3121 are nested together, with a gap between them as well. When the second housing 312 is placed on top of the first housing 311, the inner annular ribs 3121 are engaged between the two annular flanges 3111. The overlapping layers of the annular flanges 3111 and the annular ribs 3121 form a meandering barrier that prevents liquid from entering the battery housing 31, thus effectively preventing external liquid from flowing into the first housing 311 and the second housing 312. Furthermore, the sealing ring 35 is located between the annular rib 3121 in the inner layer and the annular flange 3111 in the outer layer, further sealing the space between the first housing 311 and the second housing 312, and more effectively ensuring the sealing between the first housing 311 and the second housing 312, so that external liquids or dirt will not enter the battery housing 31.

[0051] Because the battery pack 34 needs to be electrically connected to the drive unit to provide the power required for the drive unit to operate, a lead wire needs to be extended from the battery pack 34 to connect electrically to the drive unit. This is further combined with... Figure 6 and Figure 7 As shown, the second housing 312 has a through hole communicating with the inner cavity of the first housing 311. The battery assembly 3 also includes two sealing members 36, which are correspondingly sealed at the two through holes and each has a through hole suitable for the conductor wire connected to the battery pack 34 to pass through. By providing a through hole in the second housing 312 to facilitate the passage of the conductor wire, and further providing a sealing member 36 at the through hole to form a seal, and having a through hole in the sealing member 36 to form a tight connection between the sealing member 36 and the conductor wire, water can be effectively prevented from entering the battery housing 31 through the through hole and / or the through hole. Therefore, while the battery assembly 3 is fixed stably and reliably in the second cavity 14, water can dissipate heat from the battery assembly 3, and water can be prevented from entering the battery assembly 3, ensuring that the battery assembly 3 can work more stably and efficiently, thereby improving the cleaning efficiency of the pool cleaning equipment 100.

[0052] Furthermore, a handle 111 is formed on the outer casing 11. The handle 111 is located on the top of the main body 1 and at both ends of the dust box cavity 2, respectively, along with the battery assembly 3. When the pool cleaning device 100 floats on the water, since the battery assembly 3 is located at the rear end of the main body 1, the end with the handle 111 can protrude above the water first, allowing the user to better grip the handle 111 and pull the pool cleaning device 100 out of the water, making it easier for the user to operate.

[0053] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
