Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water treatment equipment accessories, in particular to a cleaning brush used in a water purifier. Background Art
[0002] Household water purifiers mainly rely on the filter element they are equipped with to filter tap water, so as to remove residual chlorine, bacteria, viruses, etc. in the tap water. In order to ensure the water production speed, there is residual water in the existing water purifier, which leads to the problem of "stale water", making it easy for bacteria to be contaminated on the filter membrane of the filter element. Bacteria gather on the filter membrane, which is prone to mildew and virus breeding. Therefore, in the prior art, the filter element needs to be disassembled regularly for cleaning, which takes a long time to disassemble and is difficult to clean, increasing the cost of use. Therefore, there is an urgent need for a cleaning brush that can automatically clean the filter element. Utility Model Content
[0003] The utility model aims to provide a cleaning brush for a water purifier, so as to solve the technical problem that the filter element of the existing water purifier needs to be regularly disassembled and cleaned, and the cleaning is difficult.
[0004] The utility model provides the following basic solutions:
[0005] The cleaning brush used in a water purifier comprises a water purifier, wherein a filter element is arranged in the water purifier, and also comprises a cleaning piece which abuts against the surface of the filter element, and the cleaning piece is used for brushing the surface of the filter element.
[0006] Beneficial effects of the basic program:
[0007] In the present application, a cleaning piece is provided to scrub the surface of the filter element, and the cleaning piece and the filter element are located in the same space, that is, both are located inside the water purifier. Compared with the prior art, the filter element can be cleaned directly by the cleaning piece without disassembling the filter element, which reduces manual operation and improves the convenience of cleaning the filter element.
[0008] With this solution, the filter element is directly scrubbed through the internal cleaning parts to reduce the accumulation of bacteria, impurities and other pollutants on the filter element surface. First, it reduces the blockage of the filter element and improves the real-time filtration efficiency. Second, it reduces the possibility of bacteria generated by the accumulation of pollutants. Third, it improves the real-time cleanliness of the filter element surface. Compared with the existing technology, there is no need to disassemble and clean the filter element, which improves the convenience of cleaning the filter element.
[0009] Furthermore, the cleaning member includes a paddle, which is coaxially arranged with the filter element and can rotate with the center of the filter element as the axis. Beneficial effect: the paddle rotates, that is, the rotating surface of the paddle overlaps with the surface of the filter element, so that the paddle rotates and cleans the surface of the filter element, and the surface of the filter element is fully cleaned by using the cleaning member with the smallest volume.
[0010] Furthermore, an elastic cleaning layer is provided on the side of the paddle facing the filter element. Beneficial effect: the elastic cleaning layer is elastic and can be deformed, thereby ensuring the contact state between the paddle and the filter element, that is, the elastic cleaning layer has a certain force on the filter element, thereby improving the cleaning effect on the surface of the filter element.
[0011] Furthermore, a plurality of protrusions are provided on the side of the elastic cleaning layer facing the filter element. Beneficial effect: With this design, the deformation of the elastic cleaning layer is increased, and the fault tolerance can be increased when installing the impeller. At the same time, the protrusions can also increase the force of the impeller on the filter element, effectively removing bacteria and impurities attached to the surface of the filter element.
[0012] Further, a plurality of protrusions are arranged in a staggered manner. Beneficial effect: With this design, a plurality of protrusions rotating with the impeller can clean any position on the surface of the filter element, thereby achieving full cleaning of the surface of the filter element.
[0013] Furthermore, the cleaning member also includes a rotating shaft, and the rotating shaft is detachably connected to the blade. Beneficial effect: the rotating shaft can be connected to a driving member and then rotated, such as a motor, and the rotation of the rotating shaft drives the blade to rotate, and the rotating blade cleans the surface of the filter element, thereby cleaning the filter element. At the same time, the blade is detachably connected, and after long-term use, the blade can be disassembled and cleaned to improve the cleanliness of the blade, thereby improving the cleaning effect of the blade on the filter element.
[0014] Furthermore, the cleaning member also includes a connecting block, which is fixedly connected to the rotating shaft, and one end of the connecting block away from the rotating shaft is detachably connected to the blade. Beneficial effect: The rotating shaft can be a driving shaft of the driving member, and it is difficult to drill a hole in the driving shaft. In this solution, a connecting block is designed to connect the blade and the rotating shaft, which is convenient for disassembly, maintenance and cleaning of the blade.
[0015] Furthermore, the blade includes blades, and the number of the blades is not less than three. Beneficial effect: With this design, the stability of the blade rotation is improved.
[0016] Furthermore, the blade includes a connecting seat and a locking piece. A limiting portion is provided on one side of the connecting seat facing the filter element. The limiting portion is hollow. A connecting hole connected to the hollow portion is provided on the other side of the connecting seat. A connecting groove is provided on one end of the connecting block facing the blade. The connecting hole and the connecting groove are threadedly connected to the same locking piece. Beneficial effect: The limiting portion is hollow. When installing the blade, the connecting block can be easily removed into the hollow through the guidance of the hollow. At the same time, the threaded connection of the locking piece improves the stability of the blade installation. The distance between the blade and the surface of the filter element can also be adjusted through the threaded connection, so that the blade can clean the surface of the filter element.
[0017] Furthermore, a reinforcement ring is provided on the connection seat, the reinforcement ring is coaxially arranged with the limiting part, and the reinforcement ring is fixedly connected to the side of the connection seat facing the filter element. Beneficial effect: With this design, the stability of the connection between the limiting part and the connection seat is improved, and it is easy to rotate the axial blade to transmit the force.
