[0029] In order to have a clearer understanding of the technical features, purposes and effects of the embodiments of the present application, the specific implementation methods of the embodiments of the present application are now described with reference to the accompanying drawings.

[0030] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0031] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one or more of the parts with the same structure or function are schematically drawn or only one or more of them are marked.

[0032] Before describing the swimming pool cleaning robot with a roller brush cleaning structure according to an embodiment of the present application, the application scenarios of the swimming pool cleaning robot are briefly described to facilitate understanding.

[0033] Reference Figures 1 to 7 The swimming pool cleaning robot generally includes a cleaning body 1 and a roller brush 2. The cleaning body 1 includes a driving motor, a filtering device 4 and other structures, and also includes a moving structure, a water inlet and a water outlet.

[0034] The specific working process is as follows: the moving structure drives the cleaning body 1 to move on the surface of the swimming pool (the surface here mainly refers to the bottom or side wall of the pool, which will not be described in detail below) through the driving motor. As the cleaning body 1 moves, the roller brush 2 spins and rolls close to the surface of the swimming pool to sweep the pollutants on the surface of the swimming pool to the bottom of the swimming pool cleaning robot. The water mixed with pollutants is sucked into the cleaning body 1 through the water inlet at the bottom of the cleaning body 1, and the pollutants are filtered through the filter device 4. The filtered water flows out from the water outlet, thereby completing the cleaning of the swimming pool surface and filtering the water in the swimming pool. However, during the cleaning process, some pollutants may adhere to the roller brush 2. As time accumulates, the pollutants on the roller brush 2 increase, resulting in a significant reduction in the cleaning effect of the roller brush 2, and at the same time, it will have an adverse effect on the service life of the roller brush 2. Therefore, in order to solve the above technical problems, the embodiment of the present application provides a swimming pool cleaning robot with a roller brush cleaning structure to achieve cleaning of the roller brush 2.

[0035] Reference Figure 1 and Figure 2The swimming pool cleaning robot includes a cleaning body 1, a roller brush 2 and a roller brush cleaning structure. The cleaning body 1 is used to clean pollutants in the swimming pool; the roller brush 2 is rotatably arranged on the cleaning body 1 and is used to clean pollutants on the surface of the swimming pool; the roller brush cleaning structure is arranged on the cleaning body 1 and contacts with at least part of the roller brush 2 to remove pollutants adhered to the roller brush 2.

[0036] The swimming pool cleaning robot with a roller brush cleaning structure in this embodiment moves through the cleaning body 1. During the movement of the cleaning body 1, the roller brush 2 spins and rolls close to the surface of the swimming pool to sweep the pollutants on the surface of the swimming pool to the bottom of the swimming pool cleaning robot. Water mixed with pollutants is sucked into the cleaning body 1 through the water inlet at the bottom of the cleaning body 1, and the pollutants are filtered through the filter device 4. The filtered water flows out from the water outlet, thereby cleaning and purifying the swimming pool. Since the roller brush cleaning structure is arranged on the cleaning body 1 and contacts at least part of the roller brush 2, during the rolling process of the roller brush 2, the pollutants remaining on the roller brush 2 are cleaned by the roller brush cleaning structure, thereby cleaning the roller brush 2, avoiding the accumulation of pollutants on the roller brush 2, affecting the cleaning effect of the roller brush 2, and avoiding adverse effects on the service life of the roller brush 2.

[0037] The structure of the swimming pool cleaning robot with a roller brush cleaning structure is described in detail below with reference to the accompanying drawings:

[0038] Figure 3 This is a schematic diagram of the structure of a roller brush of a swimming pool cleaning robot with a roller brush cleaning structure of the present application, referring to Figure 3 In a specific embodiment, the roller brush 2 may include a roller brush shaft 21, a mounting cylinder 22 and a cleaning blade assembly 23, the roller brush shaft 21 is arranged on the cleaning body 1; the mounting cylinder 22 is arranged on the roller brush shaft 21; the cleaning blade assembly 23 is detachably arranged on the outer periphery of the mounting cylinder 22, and in the process of the mounting cylinder 22 and the cleaning blade assembly 23 cooperating with the roller brush shaft 21 to rotate, at least part of the cleaning blade assembly 23 is in contact with the roller brush cleaning structure.

[0039] In one case, the roller brush shaft 21 is rotatably arranged at the bottom front end of the cleaning body 1, and the connection method can be detachably connected. Gears can be arranged at both ends of the roller brush shaft 21, and the gears are meshed with the gears of the moving structure or the gears of the driving motor to realize the rotation of the roller brush shaft 21. The mounting cylinder 22 can be fixedly connected to the roller brush shaft 21, and the cleaning blade assembly 23 can be fixedly arranged on the outer periphery of the mounting cylinder 22; when the roller brush shaft 21 rotates, the mounting cylinder 22 and the cleaning blade assembly 23 rotate at the same speed; furthermore, the roller brush shaft 21, the mounting cylinder 22 and the cleaning blade assembly 23 can be disassembled as a whole by disassembling the roller brush shaft 21, so as to facilitate replacement.

[0040] In another case, the roller brush shaft 21 can be fixedly arranged at the bottom front end of the cleaning body 1, the mounting cylinder 22 can be rotatably arranged on the roller brush shaft 21, and the cleaning blade assembly 23 can be fixedly arranged on the outer periphery of the mounting cylinder 22. The rotation of the mounting cylinder 22 drives the cleaning blade assembly 23 to push the pollutants toward the water inlet at the bottom of the cleaning body 1; specifically, when the swimming pool cleaning robot moves forward, the friction between the swimming pool surface and the cleaning blade assembly 23 can make the mounting cylinder 22 rotate around the roller brush shaft 21 to clean the swimming pool surface. Furthermore, the mounting cylinder 22 can be removed from the roller brush shaft 21. When the mounting cylinder 22 or the cleaning blade assembly 23 fails, only the mounting cylinder 22 can be replaced, without replacing the roller brush shaft 21, the mounting cylinder 22 and the cleaning blade assembly 23 as a whole, which can save costs.

[0041] In order to further save the cost of replacing the cleaning blade assembly 23, the cleaning blade assembly 23 can be detachably arranged on the outer periphery of the mounting tube 22. When the cleaning blade assembly 23 has been used for too long or the cleaning effect is not good, only the cleaning blade assembly 23 can be replaced. This is more convenient, quick and cost-effective.

[0042] Optionally, during the process of the mounting cylinder 22 and the cleaning blade assembly 23 rotating in coordination with the roller brush shaft 21, at least part of the cleaning blade assembly 23 contacts the roller brush cleaning structure, so that the cleaning blade assembly 23 can be cleaned by the roller brush cleaning structure to achieve the purpose of cleaning the roller brush 2.

[0043] Reference Figure 3 In a specific embodiment, the cleaning blade assembly 23 may include a flexible carrier 231 and at least one cleaning blade group 232, and the flexible carrier 231 is arranged around the outer periphery of the mounting tube 22; the cleaning blade group 232 can be vertically and dispersedly fixed on the flexible carrier 231, and when the flexible carrier 231 is arranged around the outer periphery of the mounting tube 22, the cleaning blade group 232 extends radially along the mounting tube 22.

[0044] The flexible bearing member 231 can be detachably disposed around the outer circumference of the installation tube 22 , and its material can be nylon, acrylic, polyester, etc.

[0045] Exemplarily, a first fastening structure is provided at one end of the flexible carrier 231 in the length direction, and a second fastening structure is provided at the other end of the flexible carrier 231, so that the two can cooperate when they need to be fixed on the mounting tube 22, and can be easily separated when they need to be disassembled.

[0046] The fastening structure can be a hook device, a snap device, etc. When the flexible carrier 231 is arranged around the outer periphery of the mounting tube 22, the first fastening structure and the second fastening structure cooperate to detachably fix the flexible carrier 231 on the mounting tube 22. When the cleaning blade assembly 23 needs to be replaced, the flexible carrier 231 can be removed from the mounting tube 22 by releasing the cooperation between the first fastening structure and the second fastening structure. This fixing method has a simple structure and is easy to disassemble, so that the replacement cost of the flexible carrier 231 is relatively low.

[0047] The cleaning blade group 232 is fixedly arranged on the flexible bearing member 231, and when the flexible bearing member 231 is arranged around the outer periphery of the mounting tube 22, the cleaning blade group 232 extends radially along the mounting tube 22. The material of the cleaning blade group 232 can be nylon, plastic, etc. One end of the cleaning blade group 232 is fixed on the flexible bearing member 231, and the other end extends radially along the mounting tube 22, so that when the roller brush 2 contacts the surface of the swimming pool, the cleaning blade group 232 keeps in contact with the surface of the swimming pool, thereby generating a large friction force, and the pollutants on the surface of the swimming pool can be swept to the bottom of the swimming pool cleaning robot. In addition, the cleaning blade group 232 is at least partially in contact with the roller brush cleaning structure, so that the cleaning blade group 232 can be cleaned by the roller brush cleaning structure, so that the pollutants attached to the surface of the roller brush 2 can be cleaned, so as to improve the cleaning effect of the roller brush 2.

[0048] In a specific embodiment, the cleaning blade group 232 may include a plurality of cleaning blades, and the cleaning blades may be arranged in a variety of ways on the flexible carrier 231. For example, the cleaning blades may be arranged in a spiral shape around the mounting tube 22, or may be arranged in sequence along the axial direction of the mounting tube 22, with a gap between two adjacent cleaning blades. By providing a gap between two adjacent cleaning blades, the cleaning blades may be effectively prevented from being tangled together, thereby affecting the cleaning effect.

[0049] In a feasible manner, the roller brush cleaning structure extends in the radial direction of the roller brush 2 so as to clean the roller brush 2 by scraping, wiping or the like.

[0050] In one embodiment, the portion of the cleaning body 1 where the roller brush 2 is mounted includes a concave arc structure, and the roller brush cleaning structure can be disposed at the bottom of the cleaning body 1 or at an appropriate position of the concave arc structure, so as to clean the roller brush 2. Figure 6 The roller brush cleaning structures can be distributed in multiple intervals along the concave arc structure, thereby improving the cleaning efficiency of the roller brush 2.

[0051] Reference Figure 4In a specific embodiment, the roller brush cleaning structure may include a mounting plate 31 and at least one cleaning tooth 32. The mounting plate 31 may be detachably connected to the cleaning body 1 by bolt connection. The mounting plate 31 may be connected in front of or behind the roller brush 2. The cleaning tooth 32 may be fixed to the mounting plate 31 by bonding or integral molding. The cleaning tooth 32 may be made of nylon, plastic, etc., and the cleaning tooth 32 may protrude toward the roller brush 2. When the roller brush 2 rolls, the cleaning tooth 32 contacts the cleaning blade of the roller brush 2 and generates friction through relative motion, so that the cleaning tooth 32 is used to clean the pollutants on the cleaning blade of the roller brush 2, thereby achieving the purpose of cleaning the roller brush 2.

[0052] In a specific embodiment, there can be multiple cleaning teeth 32, which are sequentially spaced apart along the axial direction of the roller brush 2. By setting the spacing, the contact area between the cleaning teeth 32 and the cleaning blades of the roller brush 2 is larger, and the cleaning teeth 32 have a better effect of cleaning the roller brush 2.

[0053] Reference Figure 1 In a specific embodiment, the roller brush cleaning structure may include an auxiliary brush 33 rotatably arranged on the cleaning body 1. During the rotation of the roller brush 2, at least part of the auxiliary brush 33 contacts the roller brush 2. There may be only one auxiliary brush 33. The length direction of the auxiliary brush 33 is parallel to the axial direction of the roller brush 2. The length of the auxiliary brush 33 is less than or equal to the axial length of the roller brush 2. Using one auxiliary brush 33 is convenient for installation and disassembly, and the installation cost is low. The bristles of the auxiliary brush 33 may be arranged in a spiral shape, and there are gaps between the bristles. The material of the bristles may be nylon, plastic, etc. The auxiliary brush 33 may be rotated by meshing the gears with the drive motor or the gears of the moving structure. The relative movement between the auxiliary brush 33 and the contact position of the roller brush 2 generates friction to clean the roller brush 2, and the cleaning effect is better.

[0054] Reference Figure 7 , Figure 7 : is a plan view of an auxiliary brush setting method of an embodiment of the present application. In order to further improve the cleaning effect of the roller brush 2, the auxiliary brush 33 can be set to be multiple, wherein at least one auxiliary brush 33 is set to have a length direction parallel to the axial direction of the roller brush 2, and the other auxiliary brushes 33 can be set to have a length direction perpendicular to the axial direction of the roller brush 2 or at other angles, for example, Figure 7The auxiliary brush 33 indicated by the dotted line in the middle indicates other setting angles. So that the cleaning blade assembly 23 can be cleaned from multiple angles; multiple auxiliary brushes 33 can be arranged side by side, and multiple rows can be arranged, and multiple auxiliary brushes 33 can also be arranged in a staggered manner. The length of the bristles of each auxiliary brush 33 can be set to different lengths, so that the bristles of each auxiliary brush 33 contact the cleaning blade assembly 23 of the roller brush 2 at different depths, so that pollutants contaminated at different depths of the cleaning blade assembly 23 can be cleaned, so that the cleaning effect is better. In the embodiment of the present application, the setting methods of the auxiliary brushes 33 at various angles can be selectively combined and used as needed, and the embodiment of the present application does not limit this.

[0055] Reference Figure 5 In a specific embodiment, the roller brush cleaning structure includes a cleaning nozzle 34, and the cleaning nozzle 34 is arranged on the cleaning body 1. The connection method thereof can be welding and fixing, and the material of the cleaning nozzle 34 can be stainless steel. There can be multiple cleaning nozzles 34, and multiple cleaning nozzles 34 can be arranged in sequence along the axial direction of the roller brush, and the water outlet of each cleaning nozzle 34 is facing the roller brush 2. Water is sprayed to the roller brush 2 through the cleaning nozzle 34, and the pressure of the sprayed water is used to clean the pollutants on the roller brush 2, so that the cleaning force is stronger and the cleaning effect is better. The water sprayed by multiple cleaning nozzles 34 arranged at intervals can be connected or overlapped in the range covered in the axial direction of the roller brush 2, so as to avoid that there is an uncovered area in the axial direction of the roller brush 2, which affects the cleaning effect.

[0056] In another implementation, the cleaning nozzle 34 can be hinged to the cleaning body 1 through a ball head, so that the direction of the cleaning nozzle 34 has a high degree of freedom, and can spray water to the roller brush 2 from multiple directions, with more cleaning angles, a wider cleaning range, and a better cleaning effect; when the roller brush 2 applies a force in a first direction to the cleaning nozzle 34 during the transmission process, an elastic recovery member is connected between the cleaning body 1 and the cleaning nozzle 34, and the elastic recovery member applies a force opposite to the first direction to the cleaning nozzle 34. Through the elastic recovery member connected between the cleaning body 1 and the cleaning nozzle 34, the cleaning nozzle 34 can have a position adjustment within a certain range, so that the cleaning nozzle 34 can have the function of buffering the external force of the roller brush 2 or other objects, avoiding the position change of the cleaning nozzle 34 caused by the external force, and the damage caused by the external force.

[0057] During the operation of the pool cleaning robot of this embodiment, the cleaning body 1 moves in the pool, and the roller brush 2 rotates by itself, thereby sweeping the pollutants on the surface of the pool to the bottom of the pool cleaning robot, so that the pollutants are sucked into the cleaning body 1 along with the water flow. The cleaning body 1 filters the water flow, retains the pollutants inside the filter device, and discharges the filtered water. The roller brush 2 collides with the roller brush cleaning structure during the rotation process. If there are pollutants adhering to the roller brush, the pollutants are easily removed from the roller brush 2 after the collision, which not only ensures the cleaning effect of the roller brush 2, but also prolongs its service life.

[0058] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0059] The above description is only an illustrative specific implementation of the embodiment of the present application, and is not intended to limit the scope of the embodiment of the present application. Any equivalent changes, modifications and combinations made by any technician in this field without departing from the concept and principle of the embodiment of the present application should fall within the scope of protection of the embodiment of the present application.
