Description

Technical Field

[0001] The present application relates to the technical field of cleaning tools, and in particular to a brush roller and a car washing machine thereof. Background Art

[0002] The existing contact car washing machine cannot do without a brush roller for cleaning the car body. The brush roller is composed of a motor, a brush tube, a brush sheet and a brush cover. One brush roller requires about 18 brush covers. About 12 brush sheets need to be manually installed on each brush cover. After installation, they are put on the brush tube one by one. After the brush covers at both ends are fixed, a motor is finally installed at the end of the brush tube. The motor drives the brush roller to rotate, and the brush sheet rotates under the centrifugal force to clean the car body.

[0003] There are quite a few problems. First, the brush sleeve consists of a sleeve and a tube cover. After 12 brush pieces are installed on the outer periphery of the sleeve, it is extremely difficult to fit the tube cover on the sleeve, and the assembly is extremely laborious. In addition, the tube cover often breaks during the covering process, resulting in serious wear and tear. Second, 18 brush sleeves are installed on the outer periphery of the brush tube, which significantly increases the weight of the brush roller and makes it inconvenient to carry and assemble. Third, during subsequent maintenance, if a brush piece needs to be replaced, it is necessary to unscrew the axial fixing bolts at both ends, then remove all the brush sleeves above or below it, disassemble the damaged brush sleeve and replace the brush piece, and finally reinstall all of them back on the brush tube, which is also extremely inconvenient for maintenance. Utility Model Content

[0004] One of the purposes of the present application is to provide a brush roller, which is different from the traditional assembly method of brush tubes and brush plates. A number of through holes are opened on the brush tube, and the brush plates are directly planted in the through holes of the brush tube, eliminating the brush sleeve in the traditional process. On the one hand, it simplifies the assembly process, and on the other hand, it significantly reduces the weight of the brush roller, making it more convenient to carry and assemble.

[0005] In order to solve the technical problems of heavy structure and difficult manufacturing of brush rollers in the prior art, the present application provides a brush roller, which includes a brush tube and a brush sheet; a plurality of through holes are provided in the tube wall of the brush tube, and the brush sheet is implanted in the through holes.

[0006] Furthermore, the present application provides a brush roller, which also includes a pin rod, wherein the inner end of the brush sheet passes through the through hole and forms a lasso in the inner cavity of the brush tube, and the pin rod is inserted into the lasso.

[0007] Furthermore, the present application provides a brush roller, wherein the brush sheet is bent to form a bent portion, the bent portion passes through the through hole to form the lasso, and the pin rod stops the bent portion on the inner wall of the brush tube.

[0008] Furthermore, the present application provides a brush roller, wherein both ends of the pin rod are fixed to the inner wall of the brush tube.

[0009] The second purpose of the present application is to provide a car washing machine, which uses the above-mentioned brush roller; it not only simplifies the assembly process, but also significantly reduces the weight of the brush roller, making the production and processing process easier. In addition, in actual use, if one of the brush pieces needs to be replaced, you only need to remove the corresponding pin rod, replace the damaged brush piece and reinsert the pin rod, which is extremely convenient for maintenance.

[0010] A brush roller provided by the present application has the following advantages over the prior art: on the one hand, the present application opens a through hole on the brush tube, and directly roots the brush piece in the through hole of the brush tube, eliminating the brush cover. In terms of manufacturing process, the step of first installing the brush piece on the brush cover is omitted, and the manufacturing difficulty is greatly reduced. At the same time, the weight of the brush roller is also significantly reduced, which provides convenience for transportation and assembly. On the other hand, considering the later maintenance work, if one of the brush pieces needs to be replaced, find the pin rod where the brush piece to be replaced is located, pull up the corresponding pin rod until the bent part of the brush piece to be replaced is separated from the pin rod, re-implant the replacement brush piece, and then insert the pin rod downward into the bent part again, which is also extremely convenient for later maintenance.
