Before describing a pool cleaning robot with a roller brush cleaning structure according to the embodiments of the present disclosure, an application scenario of the pool cleaning robot is briefly described for easy understanding.
Referring to
A working process of the pool cleaning robot is as follows: the moving structure drives the cleaning body 1 to move on a surface of a pool (the surface here mainly refers to the bottom or sidewalls of the pool, and detailed description thereof will be omitted below) through the drive motor. As the cleaning body 1 moves, the roller brush 2 self-rotates and rolls against the surface of the pool to sweep contaminants on the surface of the pool to the bottom of the pool cleaning robot, and water mixed with the contaminants is sucked into the cleaning body 1 through the water inlet at the bottom of the cleaning body 1. The contaminants are filtered by the filtering apparatus 4, and filtered water flows out from the water outlet, thereby completing the action of cleaning the surface of the pool and filtering water in the pool. However, during the cleaning, some contaminants may adhere to the roller brush 2. With the accumulation of time, the contaminants on the roller brush 2 increase, which may greatly reduce a cleaning effect of the roller brush 2, and at the same time may also have an adverse effect on the service life of the roller brush 2. Therefore, in order to solve the above technical problem, the embodiments of the present disclosure provide a pool cleaning robot with a roller brush cleaning structure, so as to clean the roller brush 2.
Referring to
The pool cleaning robot with a roller brush cleaning structure in the present embodiment moves through the cleaning body 1, during the movement of the cleaning body 1, the roller brush 2 self-rotates and rolls against the surface of the pool to sweep the contaminants on the surface of the pool to the bottom of the pool cleaning robot, and the water mixed with the contaminants is sucked into the cleaning body 1 through the water inlet at the bottom of the cleaning body 1. The contaminants are filtered by the filtering apparatus 4, and the filtered water flows out from the water outlet, thereby cleaning and purifying the pool. Since the roller brush cleaning structure is arranged on the cleaning body 1 and is in contact with at least part of the roller brush 2, during the rolling of the roller brush 2, the residual contaminants on the roller brush 2 are cleaned by the roller brush cleaning structure, so as to clean the roller brush 2. It is avoided that the accumulation of contaminants on the roller brush 2 may affect the cleaning effect of the roller brush 2 and that the service life of the roller brush 2 may be adversely affected.
In conjunction with the accompanying drawings, a structure of the pool cleaning robot with a roller brush cleaning structure will be specifically described as follows:
In one case, the roller brush shaft 21 is rotatably arranged at a front end of the bottom of the cleaning body 1, the connection method may be detachable connection, and both ends of the roller brush shaft 21 may be provided with gears, and the rotation of the roller brush shaft 21 may be realized by engaging the gears with gears of the moving structure or gears of the drive motor. The mounting cylinder 22 may be fixedly connected to the roller brush shaft 21, and the cleaning blade assembly 23 may 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 may be disassembled integrally by disassembling the roller brush shaft 21, thereby facilitating replacement.
In another case, the roller brush shaft 21 may be fixedly arranged at the front end of the bottom of the cleaning body 1, the mounting cylinder 22 may be rotatably arranged on the roller brush shaft 21, and the cleaning blade assembly 23 may be fixedly arranged on the outer periphery of the mounting cylinder 22. The cleaning blade assembly 23 is driven by the rotation of the mounting cylinder 22 to push the contaminants towards the water inlet at the bottom of the cleaning body 1. Specifically, when the pool cleaning robot moves forward, a frictional force between the pool surface and the cleaning blade assembly 23 may cause the mounting cylinder 22 to self-rotate around the roller brush shaft 21 to clean the pool surface. Furthermore, the mounting cylinder 22 may be detached 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.
In order to further save the cost of replacing the cleaning blade assembly 23, the cleaning blade assembly 23 may be detachably arranged on the outer periphery of the mounting cylinder 22. When the cleaning blade assembly 23 is used for too long or the cleaning effect is not good, only the cleaning blade assembly 23 can be replaced, which is more convenient, faster, and more cost-effective.
In an implementation, during the coordinating rotation of the mounting cylinder 22 and the cleaning blade assembly 23 with the roller brush shaft 21, at least part of the cleaning blade assembly 23 is in contact with the roller brush cleaning structure, so that the cleaning blade assembly 23 may be cleaned by the roller brush cleaning structure, so as to achieve the purpose of cleaning the roller brush 2.
Referring to
The flexible bearing member 231 may be detachably arranged around the outer periphery of the mounting cylinder 22, and a material of the flexible bearing member 231 may be nylon, acrylic, polyester, or the like.
For example, one end of the flexible bearing member 231 in a length direction is provided with a first fastening structure, the other end of the flexible bearing member 231 is provided with a second fastening structure, so that the first fastening structure and the second fastening structure may cooperate when they need to be fixed on the mounting cylinder 22, and may be easily separated when they need to be disassembled.
The fastening structure may be a hook apparatus, a snap apparatus, etc. When the flexible bearing member 231 is arranged around the outer periphery of the mounting cylinder 22, the first fastening structure and the second fastening structure cooperate to detachably fix the flexible bearing member 231 on the mounting cylinder 22. When the cleaning blade assembly 23 needs to be replaced, the flexible bearing member 231 may be disassembled from the mounting cylinder 22 by releasing the cooperation of the first fastening structure and the second fastening structure. The fixing method is simple in structure and convenient in disassembly, so that a replacement cost of the flexible bearing member 231 is low.
When the cleaning blade set 232 is fixedly arranged on the flexible bearing member 231, and the flexible bearing member 231 is arranged around the outer periphery of the mounting cylinder 22, the cleaning blade set 232 extends along the radial direction of the mounting cylinder 22. A material of the cleaning blade set 232 may be nylon, plastic, or the like. One end of the cleaning blade set 232 is fixed on the flexible bearing member 231, and the other end of the cleaning blade set 232 extends along the radial direction of the mounting cylinder 22, so that when the roller brush 2 is in contact with the pool surface, the cleaning blade set 232 is kept in contact with the pool surface, so as to generate a large friction force, which may sweep the contaminants on the surface of the pool to the bottom of the pool cleaning robot. In addition, the cleaning blade set 232 is at least partially in contact with the roller brush cleaning structure, so that the cleaning blade set 232 may be cleaned by the roller brush cleaning structure, so as to remove the contaminants attached to the surface of the roller brush 2, so as to improve the cleaning effect of the roller brush 2.
In a specific implementation, the cleaning blade set 232 may include a plurality of cleaning blades, and the cleaning blades may be arranged in various ways on the flexible bearing member 231. For example, the cleaning blades may be arranged in a spiral shape around the mounting cylinder 22, or may be sequentially arranged at intervals along the axial direction of the mounting cylinder 22, and there is a gap between two adjacent cleaning blades. By setting a gap between two adjacent cleaning blades, the cleaning blades are effectively prevented from being tangled together and affecting the cleaning effect.
In a feasible approach, the roller brush cleaning structure extends along a radial direction of the roller brush 2, so as to clean the roller brush 2 by scraping, rubbing or the like.
In one case, the part of the cleaning body 1 where the roller brush 2 is installed includes a concave arc structure, and the roller brush cleaning structure may be arranged at the bottom of the cleaning body 1, or may be arranged at an appropriate position of the concave arc structure, thereby cleaning the roller brush 2.

In a specific implementation, there may be a plurality of the cleaning teeth 32, and the cleaning teeth are sequentially arranged at intervals along an axial direction of the roller brush 2. By setting the intervals, a contact area between the cleaning teeth 32 and the cleaning blades of the roller brush 2 is made larger, and a cleaning effect of the cleaning teeth 32 on the roller brush 2 is better.

In another implementation, the cleaning nozzle 34 may be hinged on the cleaning body 1 through a ball joint, then an orientation of the cleaning nozzle 34 has a higher degree of freedom, and the cleaning nozzle 34 may spray water to the roller brush 2 from a plurality of directions, having more cleaning angles, wider cleaning range, and better cleaning effect. When the roller brush 2 exerts a force in a first direction on the cleaning nozzle 34 during transmission, an elastic restoring member is connected between the cleaning body 1 and the cleaning nozzle 34, and the elastic restoring member applies a force opposite to the first direction to the cleaning nozzle 34. Through the elastic restoring member connected between the cleaning body 1 and the cleaning nozzle 34, the cleaning nozzle 34 may have a position adjustment within a certain range, so that the cleaning nozzle 34 may have a function of buffering an external force exerted by the roller brush 2 or other objects, avoiding a position change and damage of the cleaning nozzle 34 caused by the external force.
During working of the pool cleaning robot of the present embodiment, the cleaning body 1 moves in the pool, at the same time, the roller brush 2 self-rotates and turns, to sweep the contaminants on the surface of the pool to the bottom of the pool cleaning robot, so that the contaminants are sucked into the cleaning body 1 with water flow, the cleaning body 1 filters the water flow, keeps the contaminants inside the filtering apparatus, and discharges the filtered water. While the roller brush 2 collides with the roller brush cleaning structure during the rotation, if there are contaminants adhered to the roller brush 2, the contaminants are easily removed from the roller brush 2 after the collision, which can not only ensure the cleaning effect of the roller brush 2, but also prolong its service life.
