[0019] To make the technical solution and beneficial effects of this utility model more apparent and understandable, a detailed description is provided below by listing specific embodiments. Unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0020] Automatic pool cleaning equipment includes surface cleaning equipment or underwater cleaning equipment. Surface cleaning equipment has a surface cleaning mode. Underwater cleaning equipment has bottom cleaning mode, wall cleaning mode, and surface cleaning mode, and can perform cleaning operations on the bottom, walls, water, and surface of a pool (e.g., a swimming pool) as needed, for example, to remove debris from the water, bottom, and surface, and to clean dirt from the pool bottom and walls. This automatic pool cleaning device may include a housing, a walking mechanism 30 (… Figure 1 Structures / components such as cleaning units. As an example, the housing includes an inlet (including a waste inlet mentioned below) and an outlet. The inlet can be located at the bottom or side of the housing for water that has not been treated for dirt, and the outlet can be located at the top or side of the housing for water that has been treated for dirt / debris to flow out. The treatment of dirt / debris includes physical changes such as filtration and adsorption and / or chemical changes such as light and chemical reactions. The treatment of dirt / debris results in the retention or removal of dirt / debris.

[0021] As an example, a control chamber, a power chamber, and a filter chamber can be arranged within the housing. The control chamber must be sealed and can house control circuits such as microprocessors, digital signal processors (DSPs), and microcontrollers. The power chamber can house drive mechanisms such as water pumps and drive motors to generate water flow or mechanical transmission force. The filter chamber can contain a filter unit such as a waste basket to filter and purify the water entering the filter chamber through the inlet, retaining impurities in the waste basket, thus achieving the function of waste / dirt treatment. The cleaned water is then discharged from the automatic water tank cleaning device through the outlet. In other words, the automatic water tank cleaning device includes a filter channel that restricts the water flow sequentially through the inlet, waste basket, and outlet to achieve waste / dirt treatment. The trash can is generally arranged in a polyhedral structure with a bottom wall, side walls, and a top wall. In some embodiments, the trash can may be generally arranged in a hexahedral shape. Its bottom wall includes a trash can water inlet corresponding to the water inlet of the shell, its four side walls include a filter structure for water flow, and its top wall includes an opening and closing structure or a detachable structure for cleaning trash. The pool includes, but is not limited to, swimming pools, water storage pools, spa pools, water storage tanks, or water storage troughs. The automatic pool cleaning equipment can be a device such as an automatic cleaning device or a pool cleaning robot, which only needs to be able to clean the pool.

[0022] Automatic water tank cleaning equipment can generally clean the water tank automatically according to received instructions or pre-compiled programs.

[0023] Sunscreen and sebum can both contribute to oil buildup in pools. Oil is difficult for existing automatic pool cleaning systems to capture on the surface, leading to long-term accumulation and water quality deterioration, impacting the pool environment. Manually removing oil from the surface also reduces cleaning efficiency. To improve oil removal, see [link to relevant documentation]. Figures 1 to 6 The embodiments of this application provide the following technical solutions.

[0024] The automatic water tank cleaning device provided in this application includes: a device body 10, a garbage bin assembly 80, and an oil suction part 90. The device body 10 has a sewage inlet 11; the garbage bin assembly 80 is disposed on the device body 10 and is connected to the sewage inlet 11; the oil suction part 90 is disposed on at least one of the device body 10 and the garbage bin assembly 80, and the oil suction part 90 is capable of absorbing oil.

[0025] During the water surface cleaning process, the oil-absorbing unit 90 moves along with the main body 10 of the equipment, continuously contacting the pool water and adsorbing oil stains to achieve cleaning. As the main body 10 moves, water flows into the waste bin assembly 80 through the inlet 11. The waste bin assembly 80 traps waste, and the filtered pool water returns to the pool. In other words, solid waste collection and oil adsorption can be carried out simultaneously, improving the cleaning efficiency of the pool.

[0026] In some embodiments, the oil-absorbing unit includes a slow-release chemical adsorption box, specifically a porous plastic box (pore size 0.5-1mm), containing an adsorbent chemical agent (such as modified bentonite or oil-absorbing resin). The box is fixed to the bottom of the robot and partially immersed in water. The agent slowly releases its adsorption capacity through the porous structure, adsorbing oil without leaching harmful substances. This setup requires no power or control; only periodic replacement of the chemical box is needed, facilitating long-term pool cleaning.

[0027] In some alternative embodiments, the device body 10 includes a roller brush 20 (see...) Figure 1 ), or, the waste bin assembly 80 includes a roller brush 20 (see Figure 3 Alternatively, both the main body 10 and the waste bin assembly 80 include a roller brush 20; the roller brush 20 is rotatable relative to the main body 10 in order to guide dirt into the inlet 11, and the oil suction part 90 is provided on the roller brush 20.

[0028] During the cleaning process, the automatic water tank cleaning equipment allows the roller brush 20 to remain rotating. Since the oil-absorbing part 90 is located within the roller brush 20, the rotating brush not only draws solid waste from the tank into the inlet 11 but also ensures the oil-absorbing part 90 makes full contact with the oil. This improves the collection efficiency of solid waste and enhances the oil adsorption effect through continuous contact. Furthermore, integrating the oil-absorbing part 90 into the roller brush 20 fully utilizes its space, resulting in improved space utilization.

[0029] Furthermore, by placing the oil-absorbing part 90 on the roller brush 20, oil stains can be absorbed before the pool water enters the garbage bin assembly 80, reducing the amount of oil stains entering the garbage bin assembly 80 and causing pollution, making it easier to clean the garbage bin assembly 80.

[0030] See Figure 2 , Figures 4 to 6 In some alternative embodiments, the roller brush 20 includes a roller core 21 and a cleaning element 22 connected to the roller core 21. An oil-absorbing portion 90 is disposed on the cleaning element 22 (see...). Figure 5 Alternatively, the oil suction section 90 is disposed on the roller core 21 (see...). Figure 4 and Figure 6 Alternatively, the oil suction section 90 is provided in both the cleaning element 22 and the roller core 21.

[0031] The roller core 21 is the supporting structure of the roller brush 20, used to connect the cleaning element 22 and transmit rotational power. The rigid structure of the roller core 21 can maintain the overall shape of the roller brush 20. The cleaning element 22 is used to sweep the water surface to guide debris into the inlet 11. The roller core 21 and the cleaning element 22 are the parts of the roller brush 20 that effectively contact the pool water. Placing the oil-absorbing part 90 on at least one of the roller core 21 and the cleaning element 22 can effectively ensure the oil absorption effect. Moreover, the roller brush 20 is generally located at the head of the automatic pool cleaning device. This arrangement allows the oil-absorbing part located on the roller core 21 and / or the cleaning element 22 to contact the oil stains at the first time, improving the oil absorption efficiency.

[0032] When the roller brush 20 is installed on the main body 10 of the equipment, the roller core 21 is rotatably connected to the main body 10 of the equipment. For example, an automatic water tank cleaning device includes a roller brush motor and a transmission assembly 70 that connects the roller brush motor and the roller core 21. The roller brush motor drives the roller core 21 to rotate through the transmission assembly 70.

[0033] When the roller brush 20 is provided on the waste bin assembly 80, the roller brush 20 is rotatably connected to the waste bin assembly 80. The roller brush 20 can be connected to components such as motors through a transmission component, or it can be disconnected from components outside the waste bin assembly 80, thereby pushing the roller brush 20 to rotate when the machine moves forward and causes the water flow to move towards the roller brush 20.

[0034] For example, the oil-absorbing part 90 is an oil-absorbing cloth attached to the surface of the roller core 21 and / or the cleaning element 22.

[0035] Oil-absorbing cloths are functional wiping materials with strong oil-absorbing properties, mainly used to absorb and remove various oil stains. Oil-absorbing cloths are typically made of polypropylene meltblown nonwoven fabric. This material has high porosity and a large specific surface area; polypropylene is almost non-absorbent but has excellent oleophilic properties, thus meltblown nonwoven fabric possesses excellent oil-absorbing performance.

[0036] The specific structures of the roller core 21 and the cleaning element 22 can be designed independently as needed, and their specific structures are not intended to limit this application. For example, the roller core 21 can be a generally cylindrical solid or hollow shaft. Figure 6 Or, as Figure 4 and Figure 5 As shown, the roller core 21 can be formed by combining two cylinders 25 at both ends and a plurality of ribs 24 located between the two cylinders 25. The cylinders 25 are used to connect the transmission assembly 70 to realize power transmission, and the ribs 24 are used to connect the cleaning element 22. For example, the cleaning element 22 can be made of... Figure 2 The strip shape shown can also be as follows: Figure 4 and Figure 5 The plate-like shape can also be as follows: Figure 6 The sheet-like shape shown.

[0037] See Figure 4 In some alternative embodiments, the roller core 21 is provided with a mounting position 23, which is connected to the sewage inlet 11, and the oil suction part 90 is at least partially disposed in the mounting position 23.

[0038] The mounting position 23 includes, but is not limited to, a recess or through structure in the roller core 21 for accommodating the oil suction part 90. For example, the mounting position 23 can be implemented by means of annular groove, strip groove, through hole or honeycomb hole. Figure 4 and Figure 5 Specifically, the through-hole structure shown is a through hole. The mounting position 23 can physically limit the oil suction part 90 to form a stable connection with the roller core 21, reducing or even preventing the oil suction part 90 from shifting or detaching from the roller brush 20 when the roller brush 20 rotates at high speed.

[0039] The mounting position 23 is in fluid communication with the inlet 11. The oil-absorbing part 90 located in the mounting position 23 can absorb the oil in the pool water and perform preliminary filtration of the pool water. The filtered pool water continues to flow towards the inlet 11.

[0040] See Figure 4 and Figure 6 In some alternative embodiments, the number of cleaning elements 22 is multiple, and the multiple cleaning elements 22 are arranged circumferentially at intervals on the roller core 21. The number of oil suction parts 90 includes at least one, and an oil suction part 90 is located between two cleaning elements 22.

[0041] Figure 4 and Figure 6 Only one oil-absorbing section 90 is shown as an example; the number of oil-absorbing sections 90 can be increased as needed.

[0042] See Figure 4 , Figure 4 Three plate-shaped cleaning elements 22 are shown, with an oil-absorbing portion 90 positioned between two cleaning elements 22 along the axial direction of the roller brush 20. Alternatively, see... Figure 6 The oil-absorbing part 90 can be positioned between the two cleaning elements 22 along the circumference of the roller brush 20. The installation position of the oil-absorbing part 90 can be adjusted according to the arrangement of the cleaning elements 22.

[0043] In some alternative embodiments, the oil-absorbing portion 90 includes an oil-loving material or structure. This oil-absorbing portion 90 can improve the adsorption capacity and efficiency of oil stains.

[0044] Oleophilic materials are substances whose surface energy is lower than that of the oil phase and which have van der Waals forces with oil molecules. For example, oleophilic materials can be made of polypropylene fibers, polyurethane foam, or silicone-based composite materials.

[0045] The oleophilic structure can be achieved by using a porous honeycomb matrix, a wrinkled surface, or a capillary bundle array. Such structures enhance the oil capture capability by expanding the adsorption interface.

[0046] In some alternative embodiments, see Figure 3 The garbage bin assembly 80 also includes a garbage bin body 83 and a filter screen (not shown) disposed on the garbage bin body 83. The garbage bin body 83 includes a bin opening 81, which is provided corresponding to the sewage inlet 11. An oil suction part 90 is disposed on the filter screen, or the oil suction part 90 is disposed inside the garbage bin body 83, or the oil suction part 90 is disposed on both the filter screen and the garbage bin body 83.

[0047] The garbage bin itself 83 can be Figure 3 The garbage basket shown has a collection chamber 82 inside. A filter screen can be installed on the side wall of the garbage basket. After the pool water enters the collection chamber 82 through the sewage inlet 11 and the compartment opening 81, it is filtered by the filter screen and the oil absorption part 90 to remove oil and garbage before flowing out of the garbage basket.

[0048] Optionally, the oil-absorbing part 90 can be suspended or placed inside the collection chamber 82. In this way, when the automatic water cleaning equipment cleans the water surface, the oil-absorbing part 90 floats on the water surface due to buoyancy, which can effectively ensure the oil removal effect.

[0049] For example, the oil-absorbing part 90 includes a sponge that is connected to the garbage bin body 83 and suspended or placed inside the garbage bin body 83.

[0050] Optionally, when the oil suction part 90 is provided on the main body 10 of the equipment, the oil suction part 90 is detachably connected to the main body 10 of the equipment. When the oil suction part 90 is provided on the waste bin assembly 80, the oil suction part 90 is detachably connected to the waste bin assembly 80. If the oil suction part 90 is provided on both the main body 10 of the equipment and the waste bin assembly 80, the oil suction part 90 is detachably connected to both the main body 10 of the equipment and the waste bin assembly 80 respectively.

[0051] After the equipment completes its cleaning task, the waste bin assembly 80 can be removed from the main body 10 to remove solid waste. The oil-absorbing section 90 can be disassembled separately to replace or clean the absorbent material. Once the oil-absorbing section 90 is saturated, it can be easily and quickly replaced with a new one using the detachable connection. The replaced oil-absorbing section 90 can be reused after cleaning.

[0052] Unrestricted, detachable connection methods include at least one of the following: Velcro connection, magnetic connection, and snap-fit.

[0053] In some alternative embodiments, the automatic pool cleaning device also includes a power system, which includes a buoyancy mechanism 40 (see...). Figure 2 At least one of the following: ) and the walking mechanism 30.

[0054] The buoyancy mechanism 40 is used to adjust buoyancy so that the automatic pool cleaning equipment floats in the pool. For example, the buoyancy mechanism 40 includes an air pump, an air bladder, and an air storage chamber. When the automatic pool cleaning equipment needs to float to the surface for cleaning, the air pump can be controlled to inflate the air bladder with gas from the air storage chamber, increasing the equipment's buoyancy and causing it to float. Conversely, when the automatic pool cleaning equipment needs to clean inside the pool, the air pump can be used to pump the gas back from the air bladder into the air storage chamber, reducing the equipment's buoyancy and causing it to sink. By adjusting the inflation level of the air bladder, the magnitude of the buoyancy acting on the equipment can be adjusted.

[0055] The power system includes a walking mechanism 30, which is located on both sides of the main body 10 to control the movement of the automatic water tank cleaning equipment inside or outside the water tank. For example, the walking mechanism 30 can be made of wheels or tracks. Independently controlled walking mechanisms 30 can be installed on opposite sides of the main body 10 to enable functions such as turning and obstacle crossing. Using the walking mechanism 30, the automatic water tank cleaning equipment can move along the pool wall below the water surface to clean the pool wall. It can also move to a base station outside the water tank when cleaning is complete or when maintenance such as charging is required.

[0056] In some alternative embodiments, the automatic pool cleaning device also includes a sensing system and a control system 50 disposed on the main body 10 of the device (see Figure 2 The sensing system is used to identify garbage or oil stains at least; the control system 50 is connected to the sensing system and the power system respectively, and the control system 50 can perform path planning based on the identified garbage and oil stains, and control the power system to drive the main body of the equipment 10 to move along the planned path.

[0057] The sensing system is used to detect at least the distribution of pollutants on the water surface. For example, the sensing system includes an infrared sensor array, a camera vision recognition module, or an ultrasonic sensor 60 (see...). Figure 2 At least one of these, through multi-sensor data fusion technology, can capture the location of floating objects on the water surface and the spatial coordinates of oil accumulation areas in real time.

[0058] The control system 50 processes the sensed data and generates motion commands. For example, an embedded processor equipped with a path planning algorithm can be used to implement control, and a clean path sequence can be generated by establishing an environmental map model and using a region coverage optimization algorithm.

[0059] For example, the control method of an automatic water tank cleaning device includes the following steps: S10. When the pool cleaning equipment is floating on the water surface, it identifies oil and / or garbage on the water surface; S20. Based on oil stains and / or garbage, plan the cleaning path; S30, Clean up trash and / or oil stains based on cleaning paths.

[0060] In step S10, when the equipment is cleaning the water surface, a camera can capture images of the water surface and identify reflective areas of oil stains through color space analysis. Simultaneously, an infrared sensor detects the outline coordinates of solid waste. The collected data, after filtering, is input into the path planning module to generate a cleaning path that includes both oil stains and waste. The power system controls the differential steering of the two side wheels based on the path coordinates, enabling the equipment to clean the oil stains and waste along the planned trajectory.

[0061] In some embodiments, the automatic pool cleaning device may also include a battery, which may be powered by a solar panel or a rechargeable battery, to support the device's long-term operation in the pool.
