Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a cleaning roller brush and a cleaning tool. Background Art

[0002] Existing cleaning tools for cleaning floors typically use a roller that works in conjunction with a garbage channel to sweep solid waste and dust into a trash bin to achieve cleaning. The roller is typically a sponge roller, and during the cleaning process, solid waste and long, thin strips of waste, such as hair and lint, often cling to the sponge surface of the roller. This increases resistance during long-term use, thus affecting usability. Therefore, timely cleaning is necessary. Existing cleaning tools are therefore equipped with a cleaning brush that rotates synchronously with the roller during cleaning. The cleaning brush contacts the surface of the sponge roller, effectively removing solid waste, long, thin strips of waste, and dust clinging to the sponge roller surface and moving them into a trash bin. In pursuit of a compact structure and improved cleaning results, the distances between the cleaning brush and the end of the sponge roller and the end of the shovel bar are different, with the former typically being greater than the latter. This increases resistance to the cleaning brush during use, affecting the cleaning effect. When the cleaning brush is driven by a motor or transmission mechanism, power consumption increases.

[0043] The solution of this application will be described in detail below with reference to the accompanying drawings.

[0044] Figures 1-10 As shown, the present invention provides an embodiment of a cleaning roller brush.

[0045] The cleaning roller brush 1 includes a brush body 10 and at least two groups of bristles arranged along the circumference of the brush body 10 . Each group of bristles is arranged along the length direction of the brush body 10 , and the lengths of the at least two groups of bristles are different.

[0046] Specifically, the brush body 10 is provided with a first group of bristles 12 and a second group of bristles 11, wherein the first group of bristles 12 is longer than the second group of bristles 11. The bristles can be arranged in multiple groups as needed. This embodiment takes three groups of bristles as an example. Each group of bristles is evenly distributed in the circumferential direction of the brush body 10, and each group of bristles consists of multiple bristles in the length direction. During installation, the cleaning roller brush 1 is arranged in the housing A and is parallel to the cleaning roller 2 to ensure that the long bristles can contact the surface of the cleaning roller 2. A garbage channel is provided between the cleaning roller 2 and the shovel bar C. A guide surface C1 is provided at the end of the shovel bar C to guide the garbage to the garbage box B. The guide surface C1 is a sloped structure.

[0047] Since two sets of bristles of different lengths are provided, the garbage on the surface of the sponge roller 2 farther away can be cleaned and collected into the garbage box B during operation, thereby improving the cleaning effect. Since the bristles are of different lengths in the circumferential direction, they can intermittently contact between the sponge roller 2 and the shovel bar C during cleaning, reducing resistance during operation.

[0048] In order to reduce the contact resistance when cleaning the surface of the sponge roller 2, each group of bristles is distributed non-linearly in the length direction, so that only a part of each group of bristles contacts the surface of the sponge roller 2 during use.

[0049] In order to better clean the surface of the sponge roller 2, the cleaning roller brush 1 also includes a horizontal movement mechanism that moves periodically along the axis of rotation. The horizontal movement mechanism includes a guide groove (not shown in the drawings) for water movement between the brush body 10 and the brush axis 15, and a guide bar 101 that cooperates with the guide groove. A moving block 14 is provided at one end of the brush body 10 to cause the brush body 10 to perform periodic linear motion. That is, the moving block 14 cooperates with one end of the brush body 10 to achieve periodic linear motion of the brush body 10. A cavity 102 is provided between the other end of the brush body 10 and the brush axis 15. A spring 16 is provided in the cavity to bring the brush body 10 into contact with the moving block 14. That is, the spring 16 is mounted on the brush axis 15 and housed in the cavity 102, so that one end of the brush body 10 maintains contact with the moving block 14. During operation, the brush body 10 rotates synchronously with the brush shaft 15 and the brush body 10 , and the brush body 10 and the brush shaft 15 move linearly through the cooperation of the guide bar 101 that cooperates with the guide groove.

[0050] The contact surface between the movable block 14 and the brush body 10 is provided with at least two protrusions 141, with grooves 142 provided between adjacent protrusions 141, and the grooves 142 and protrusions 141 being smoothly connected. Since the grooves 142 and protrusions 141 are smoothly connected, when the brush shaft 15 rotates, one end of the brush body 10 cooperates with the grooves 142 and protrusions 141 on the fixed movable block 14 to achieve continuous downward linear movement, thereby converting a single rotation into a linear motion that is synchronous with the rotation, thereby better cleaning the surface of the sponge roller 2.

[0051] As needed, the number of the grooves 142 can be set as needed. It is best to set it to two to four from the aspects of reducing noise, process difficulty, and required movement frequency.

[0052] As needed, the horizontal movement mechanism can also adopt the following structure, which includes a guide groove (not shown in the drawings) for water movement between the brush body 10 and the brush shaft 15, and a guide bar 101 that cooperates with the guide groove. At both ends of the brush body 10, there are circumferentially provided with moving blocks 14 that cause the brush body to perform periodic linear motion. Each moving block 14 has at least two protrusions 141 on the contact surface with the brush body 10, and a groove 142 is provided between adjacent protrusions 141. The grooves 142 are smoothly connected to the protrusions 141. The protrusions 141 and grooves 142 at both ends are staggered. The staggered arrangement specifically means that the protrusions 141 and grooves 142 correspond to the same straight line, that is, when one end is at the top of the protrusion 141, the other end is at the bottom of the groove 142. This ensures that linear motion can be achieved without motion interference.

[0053] The present invention also provides a cleaning tool, which includes a shell A and a cleaning roller 2 arranged on the shell A, and a cleaning roller brush 1 arranged parallel to the cleaning roller 2, wherein the cleaning roller brush 1 includes a brush body 10 and at least two groups of bristles arranged along the circumferential direction of the brush body, each group of bristles is arranged along the length direction of the brush body, and the lengths of at least two groups of bristles are different.

[0054] Specifically, the brush body 10 is provided with a first group of bristles 12 and a second group of bristles 11, wherein the first group of bristles 12 is longer than the second group of bristles 11. The bristles can be arranged in multiple groups as needed. This embodiment takes three groups of bristles as an example. Each group of bristles is evenly distributed in the circumferential direction of the brush body 10, and each group of bristles consists of multiple bristles in the length direction. During installation, the cleaning roller brush 1 is arranged in the housing A and is parallel to the cleaning roller 2 to ensure that the long bristles can contact the surface of the cleaning roller 2. A garbage channel is provided between the cleaning roller 2 and the shovel bar C. A guide surface C1 is provided at the end of the shovel bar C to guide the garbage to the garbage box B. The guide surface C1 is a sloped structure.

[0055] Since two sets of bristles of different lengths are provided, the garbage on the surface of the sponge roller 2 farther away can be cleaned and collected into the garbage box B during operation, thereby improving the cleaning effect. Since the bristles are of different lengths in the circumferential direction, they can intermittently contact between the sponge roller 2 and the shovel bar C during cleaning, reducing resistance during operation.

[0056] In order to reduce the contact resistance when cleaning the surface of the sponge roller 2, each group of bristles is distributed non-linearly in the length direction, so that only a part of each group of bristles contacts the surface of the sponge roller 2 during use.

[0057] Optionally, the cleaning tool also includes a scooping bar C that forms an arc-shaped trash channel with the cleaning roller 2. A guide surface C1 pointing toward the trash bin D is located at the end of the scooping bar C. The guide surface C1 is equipped with multiple comb-like protrusions C2, with combing grooves C3 located between adjacent comb-like protrusions C2. The combing grooves C3 accommodate the longer bristles. The height of the comb-like protrusions C2 is limited to the difference between the longer bristles and the shorter bristles, thereby reducing resistance between the longer bristles and the guide surface C1 during operation.

[0058] In order to better clean the surface of the sponge roller 2, the cleaning roller brush 1 also includes a horizontal movement mechanism that moves periodically along the axis of rotation. The horizontal movement mechanism includes a guide groove (not shown in the drawings) for water movement between the brush body 10 and the brush axis 15, and a guide bar 101 that cooperates with the guide groove. A moving block 14 is provided at one end of the brush body 10 to cause the brush body 10 to perform periodic linear motion. That is, the moving block 14 cooperates with one end of the brush body 10 to achieve periodic linear motion of the brush body 10. A cavity 102 is provided between the other end of the brush body 10 and the brush axis 15. A spring 16 is provided in the cavity to bring the brush body 10 into contact with the moving block 14. That is, the spring 16 is mounted on the brush axis 15 and housed in the cavity 102, so that one end of the brush body 10 maintains contact with the moving block 14. During operation, the brush body 10 rotates synchronously with the brush shaft 15 and the brush body 10 , and the brush body 10 and the brush shaft 15 move linearly through the cooperation of the guide bar 101 that cooperates with the guide groove.

[0059] The contact surface between the movable block 14 and the brush body 10 is provided with at least two protrusions 141, with grooves 142 provided between adjacent protrusions 141, and the grooves 142 and protrusions 141 being smoothly connected. Since the grooves 142 and protrusions 141 are smoothly connected, when the brush shaft 15 rotates, one end of the brush body 10 cooperates with the grooves 142 and protrusions 141 on the fixed movable block 14 to achieve continuous downward linear movement, thereby converting a single rotation into a linear motion that is synchronous with the rotation, thereby better cleaning the surface of the sponge roller 2.

[0060] As needed, the number of the grooves 142 can be set as needed. It is best to set it to two to four from the aspects of reducing noise, process difficulty, and required movement frequency.

[0061] As needed, the horizontal movement mechanism can also adopt the following structure, which includes a guide groove (not shown in the drawings) for water movement between the brush body 10 and the brush shaft 15, and a guide bar 101 that cooperates with the guide groove. At both ends of the brush body 10, there are circumferentially provided with moving blocks 14 that cause the brush body to perform periodic linear motion. Each moving block 14 has at least two protrusions 141 on the contact surface with the brush body 10, and a groove 142 is provided between adjacent protrusions 141. The grooves 142 are smoothly connected to the protrusions 141. The protrusions 141 and grooves 142 at both ends are staggered. The staggered arrangement specifically means that the protrusions 141 and grooves 142 correspond to the same straight line, that is, when one end is at the top of the protrusion 141, the other end is at the bottom of the groove 142. This ensures that linear motion can be achieved without motion interference.

[0062] The embodiments of the present application are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only intended to help understand the method and core ideas of the present application. At the same time, changes or modifications made by those skilled in the art based on the ideas of the present application, the specific implementation methods, and the scope of application of the present application, all fall within the scope of protection of the present application. In summary, the contents of this specification should not be construed as limiting the present application.
