Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and particularly to a rolling brush, a floor brush assembly and a floor washer. Background Art

[0002] With the changes in the existing social environment and people's pursuit of health, and along with the improvement of living standards, people's requirements for the home living environment are getting higher and higher. In order to better clean the dirty floor and ensure the cleaning quality, floor washers that integrate floor washing, mopping and vacuuming functions have emerged in the market, with obvious cleaning effect and convenient use.

[0003] One of the key components of a floor washer is the floor brush assembly. The floor washer drives the rolling brush in the floor brush assembly to rotate through a motor, which is in close contact with the floor to brush the floor stains, and then uses a blower to generate negative pressure to suck away the stains, so as to achieve the purpose of cleaning the floor.

[0004] However, in actual operation, when brushing the floor, when encountering stubborn dirt, it is necessary to repeatedly mop the floor many times to brush the stubborn dirt off the floor, resulting in low work efficiency and unsatisfactory floor washing effect.

[0005] Application Content

[0006] Based on this, in view of the problems of low work efficiency and unsatisfactory floor washing effect of the existing floor washers, the present application provides a rolling brush, a floor brush assembly and a floor washer, which have the technical effects of high work efficiency and good floor washing effect.

[0007] A rolling brush, comprising:

[0008] A rolling brush body, which can rotate around its own axis and has an installation cavity;

[0009] A bracket, assembled in the installation cavity and rotating synchronously with the rolling brush body. The bracket has a plurality of installation pipes arranged at intervals along the axis of the rolling brush body, and each installation pipe extends along the radial direction of the rolling brush body; and

[0010] A plurality of moving parts, and at least one of the moving parts is installed in each installation pipe;

[0011] Wherein, each installation pipe has a movement channel extending along the radial direction of the rolling brush body, and each movement channel has at least one opening facing the rolling brush body;

[0012] Each moving part can move along the corresponding movement channel to the opening along with the rotation of the installation pipe where it is located, and strike the rolling brush body.

[0013] Thus, when the brush roller body rotates about its own axis, a centrifugal force is generated to throw the moving member towards the position of the movement channel close to the brush roller body, i.e., the position with an opening. When the brush roller body rotates to a position where the extension direction of one or some of the mounting pipes is parallel to the direction of gravity, the moving member moves directly to the opening under the combined action of gravity and centrifugal force and impacts the cavity wall on the side of the brush roller body facing the mounting cavity, exerting a pressing force on the ground on the brush roller. Thus, when the brush roller cleans the ground, the pressing force of the brush roller on the ground is significantly increased, and various stubborn dirt can be easily scrubbed off the ground, with high cleaning efficiency and good floor washing effect.

[0014] In one embodiment, both opposite ends of the mounting pipe in its own extension direction have the opening;

[0015] The moving member can reciprocate between the two openings on both sides along the corresponding movement channel as the brush roller body rotates.

[0016] In one embodiment, at least two of the mounting pipes extend along different radial directions of the brush roller body.

[0017] In one embodiment, every two adjacent mounting pipes extend along different radial directions of the brush roller body.

[0018] In one embodiment, every three adjacent mounting pipes extend along three different radial directions of the brush roller body respectively, and the angle between the axes of any two of every three adjacent mounting pipes is 60 degrees.

[0019] Thus, a plurality of mounting pipes extending along the first radial direction, a plurality of mounting pipes extending along the second radial direction, and a plurality of mounting pipes extending along the third radial direction can be formed. While the plurality of mounting pipes are arranged at intervals along the axial direction of the brush roller body, they can also be evenly arranged along the circumferential direction of the brush roller body, evenly dividing the circumferential degree, ensuring that the brush roller can evenly transfer the pressing force to the ground and further ensuring the stability of the cleaning effect.

[0020] In one embodiment, the moving member includes one or more steel balls.

[0021] In one embodiment, the bracket is made of noise-reducing material. To reduce the noise generated by the moving member rolling back and forth in the movement channel during the movement of the brush roller body, so as to ensure that the brush roller remains silent or has very little noise when scrubbing the ground, thereby improving the user experience.

[0022] In one embodiment, the brush roller further includes an end cap assembly, and the end cap assembly is arranged at both axial ends of the brush roller body to close the mounting cavity and drive the brush roller body to rotate about its own axis.

[0023] In one embodiment, the end cap assembly is detachably connected to the roller brush body.

[0024] In this way, when the roller brush is too dirty or has problems, the user only needs to replace the roller brush body, avoiding the replacement of the entire roller brush, thereby reducing costs.

[0025] According to another aspect of the present application, a floor brush assembly is provided, including a housing and the roller brush according to any one of the above embodiments. The roller brush is assembled in the housing and rotatably connected to the housing.

[0026] According to another aspect of the present application, a floor washer is provided, including the floor brush assembly according to the above embodiment. When the floor washer is working, the roller brush of the roller brush assembly is in close contact with the ground. When a part of the mounting tube rotates to be parallel to the direction of gravity, due to the influence of its own gravity, the moving part falls from the high point of the bracket, generating impact and vibration on the roller brush body. At the same time, due to the high-speed rotation of the roller brush body, the moving part will also generate a certain centrifugal force. Eventually, the roller brush body will be subjected to the superposition of impact vibration and centrifugal force, significantly enhancing the pressing force of the roller brush body on the ground. Compared with simply increasing the weight of the roller brush body (such as setting the roller brush body to be solid, to achieve the same pressing force, the volume needs to be made larger, or adding a counterweight will result in higher costs), the floor washer provided by the present application has better cleaning effect and performance and lower costs.

[0027] The above roller brush is used to clean the position to be cleaned, such as the ground. The roller brush specifically includes a roller brush body, a bracket and a plurality of moving parts. The roller brush body can rotate around its own axis and has an installation cavity. The bracket is assembled in the installation cavity and rotates synchronously with the roller brush body. The bracket has a plurality of mounting tubes arranged at intervals along the axial direction of the roller brush body. Each mounting tube extends radially along the roller brush body and at least one moving part is installed in each mounting tube. Wherein, each mounting tube has a movement channel extending radially along the roller brush body, and each movement channel has at least one opening facing the roller brush body. Each moving part can move along the corresponding movement channel to the opening along with the rotation of the mounting tube where it is located and impact the roller brush body. In this way, when the roller brush body rotates around its own axis, a centrifugal force is generated to throw the moving parts towards the position of the movement channel close to the roller brush body, that is, the position with the opening. When the roller brush body rotates to a position where the extension direction of one or some of the mounting tubes is parallel to the direction of gravity, the moving parts move directly to the opening under the combined action of gravity and centrifugal force and impact the cavity wall on the side of the roller brush body facing the installation cavity, applying a pressing force to the roller brush body. Thus, when cleaning the ground, the pressing force of the roller brush on the ground is significantly increased, and the dirt can be easily scrubbed off the ground, with high cleaning efficiency and good floor washing effect.

[0039] Referring to Figures 1 to 4 , an embodiment of the present application provides a rolling brush 100 for cleaning a position to be cleaned, such as the ground. The rolling brush 100 specifically includes a rolling brush body 10, a bracket 20 and a plurality of moving parts 30. The rolling brush body 10 can rotate around its own axis and has an installation cavity 11. The bracket 20 is assembled in the installation cavity 11 and rotates synchronously with the rolling brush body 10. The bracket 20 has a plurality of installation tubes 21 arranged at intervals along the axis of the rolling brush body 10. Each installation tube 21 extends radially along the rolling brush body 10 and at least one moving part 30 is installed in each installation tube 21. Wherein, each installation tube 21 has a movement channel 211 extending radially along the rolling brush body 10. Each movement channel 211 has at least one opening facing the rolling brush body 10. Each moving part 30 can move along the corresponding movement channel 211 to the opening as the installation tube 21 where it is located rotates, and hits the rolling brush body 10.

[0040] Thus, when the roller brush body 10 rotates about its own axis, a centrifugal force is generated to throw the moving member 30 towards the position of the movement channel 211 close to the roller brush body 10, that is, the position with an opening. When the roller brush body 10 rotates to a position where the extension direction of one or some of the mounting tubes 21 is parallel to the direction of gravity, the moving member 30 moves directly to the opening under the combined action of gravity and centrifugal force and impacts the cavity wall on the side of the roller brush body 10 facing the mounting cavity 11, exerting a pressing force on the roller brush body 10. Thus, when the roller brush 100 cleans the ground, the pressing force of the roller brush 100 on the ground is significantly increased, and various stubborn dirt can be easily scrubbed off the ground, with high cleaning efficiency and good floor washing effect.

[0041] Specifically, referring to Figure 1 , in some embodiments, both opposite ends of the mounting tube 21 in its own extension direction have openings, and the moving member 30 can reciprocate between the openings on both sides along the corresponding movement channel 211 as the roller brush body 10 rotates. No matter which side opening the moving member 30 rolls to, it can impact the roller brush body 10. In this solution, the movement path of each moving member 30 in the corresponding movement channel 211 is greater than the radius length of the roller brush body 10 and less than or equal to the diameter length of the roller brush body 10. Thus, the movement distance of the moving member 30 is lengthened, so that the speed at which the moving member 30 impacts the roller brush body 10 is greater, the pressing force is increased, and the cleaning efficiency and cleaning effect can also be further improved.

[0042] In one embodiment, referring to Figure 1 , at least two mounting tubes 21 extend along different radial directions of the roller brush body 10, that is, a plurality of mounting tubes 21 are staggered in the circumferential direction of the roller brush body 10 and do not face the same direction, forming at least two movement channels 211 extending along different radial directions. When the roller brush body 10 rotates about its own axis, it can ensure that there are multiple situations where the extension direction of the mounting tube 21 is parallel to the direction of gravity during the rotation process.

[0043] Thus, a plurality of moving members 30 located in different movement channels 211 continuously exert a pressing force on the roller brush body 10 under the combined action of gravity and centrifugal force. Thus, during the process of the roller brush body 10 rotating to clean the ground, the pressing force is applied to the ground multiple times, rather than being achieved only when rotating to a certain angle, thereby further improving the cleaning effect and cleaning efficiency.

[0044] Furthermore, every two adjacent mounting tubes 21 extend along different radial directions of the roller brush body 10, avoiding the situation where multiple adjacent mounting tubes 21 all extend along the same radial direction of the roller brush body 110, ensuring that the adjacent mounting tubes 21 are staggered, so that the action of the pressing force is uniform.

[0045] Preferably, referring to Figure 4, in some embodiments, every three adjacent mounting tubes 21 extend along three different radial directions of the brush roller body 10 respectively, and the angle A between the axes of every two of every three adjacent mounting tubes 21 is 60 degrees. That is, the plurality of mounting tubes 21 have a total of three extension directions, defined as the first radial direction, the second radial direction, and the third radial direction, and the angle A between the first radial direction, the second radial direction, and the third radial direction is 60 degrees.

[0046] Specifically, along the axial direction of the brush roller body 10, the mounting tubes 21 are arranged in the following manner: one mounting tube 21 extends along the first radial direction, one mounting tube 21 extends along the second radial direction, and one mounting tube 21 extends along the third radial direction, and then it repeats in a cycle, starting from the mounting tube 21 extending along the first radial direction and repeating the arrangement, forming a periodic arrangement pattern with three mounting tubes 21 as a group. In this way, a plurality of mounting tubes 21 extending along the first radial direction, a plurality of mounting tubes 21 extending along the second radial direction, and a plurality of mounting tubes 21 extending along the third radial direction can be formed. While the plurality of mounting tubes 21 are arranged at intervals along the axial direction of the brush roller body 10, they can also be evenly arranged along the circumferential direction of the brush roller body 10, evenly dividing the 360 degrees in the circumferential direction, ensuring that the brush roller 100 can evenly transfer the pressing force to the ground, and further ensuring the stability of the cleaning effect.

[0047] In some embodiments, a main shaft (not shown in the figure) coaxial with the brush roller body 10 can also be provided at the axial center position of the brush roller body 10. The plurality of mounting tubes 21 are spaced apart along the extension direction of the main shaft and along the circumferential direction of the main shaft. One end of the mounting tube 21 is connected to the main shaft, and the other end extends toward the side close to the brush roller body 10 along the radial direction of the brush roller body 10, and is provided with an opening facing the brush roller body 10. In this way, the movement path of each moving member 30 in the corresponding movement channel 211 is less than or equal to the radius length of the brush roller body 10. In this way, when the brush roller body 10 rotates, the moving member 30 in the mounting tube 21 whose extension direction is parallel to the gravity direction can move the shortest distance to hit the brush roller body 10, thereby accelerating the generation speed of the pressing force, and also further improving the cleaning efficiency and the cleaning effect.

[0048] And whether to provide one opening or two openings for each movement channel 211 can be specifically designed according to the actual use situation, and the present application does not make a limitation here.

[0049] In one embodiment, the moving member 30 includes one or more steel balls, which are specifically set according to the allowable accommodation capacity of the movement channel 211 formed by the mounting tube 21. When the one or more steel balls are sequentially placed into the movement channel 211 of the mounting tube 21, the one or more steel balls can be centrifuged when the brush roller body 10 rotates and move toward the side close to the brush roller body 10, instead of swaying back and forth in other directions, thereby forcefully hitting the brush roller body 10 and applying a pressing force to the ground.

[0050] In one embodiment, the bracket 20 is made of a noise reduction material on the basis of ensuring strength, so as to reduce the noise generated by the moving part 30 rolling back and forth in the movement channel 211 during the movement of the roller brush body 10, thereby ensuring that the roller brush 100 remains silent or makes very little noise when scrubbing the ground, so as to improve the user experience.

[0051] In one embodiment, the roller brush 100 further includes an end cap assembly. The end cap assembly is arranged at both axial ends of the roller brush body 10 to close the installation cavity 11, and drives the roller brush body 10 to rotate along its own axis. One side of the end cap assembly facing away from the roller brush body 10 is rotatably assembled on other installation structures, so that the rotation of the end cap assembly relative to other installation structures drives the roller brush body 10 to rotate, thereby realizing the rotary scrubbing of the ground.

[0052] Specifically, the end cap assembly includes a first end cap 41 and a second end cap 42. The first end cap 41 and the second end cap 42 are arranged at both axial ends of the roller brush body 10 to close the installation cavity 11.

[0053] In one embodiment, the end cap assembly is detachably connected to the roller brush body 10. When the roller brush 100 is too dirty or has problems, the user only needs to replace the roller brush body 10, avoiding the replacement of the entire roller brush 100, thereby reducing the cost. Specifically, the first end cap 41 can be set to be threadedly connected to the roller brush body 10, and the second end cap 42 is detachably connected to the other axial end of the roller brush body 10. When replacing the roller brush body 10, as long as the second end cap 42 is separated from the roller brush body 10 and the first end cap 41 at the other end is unscrewed, the end cap assembly can be removed from the roller brush body 10.

[0054] Specifically, during assembly, take a new roller brush body 10, place the moving part 30 into the movement channel 211 of the bracket 20 in sequence. Each movement channel 211 can accommodate one or more steel balls according to the size of the bracket 20. Then push the bracket 20 into the installation cavity 11 of the roller brush body 10, and finally cover both axial ends of the roller brush body 10 through the first end cap 41 and the second end cap 42 to close the installation cavity 11, thus completing the assembly of the roller brush 100.

[0055] According to another aspect of the present application, a floor brush assembly is provided, including a housing and the roller brush 100 provided in any of the above embodiments. The roller brush 100 is assembled in the housing and is rotatably connected to the housing, thereby completing the cleaning of the floor brush assembly at the position to be cleaned. Specifically, the roller brush 100 is rotatably connected to the housing through the end cap assembly.

[0056] In this way, the present application sets the bracket 20 assembled in the installation cavity 11, and the bracket 20 has a plurality of installation tubes 21 arranged at intervals along the axis of the roller brush body 10.

[0057] Each mounting tube 21 extends radially along the brush roller body 10, and at least one moving member 30 is installed in each mounting tube 21. Among them, each mounting tube 21 has a movement channel 211 extending radially along the brush roller body 10, and each movement channel 211 has at least one opening facing the brush roller body 10. Each moving member 30 can move along the corresponding movement channel 211 to the opening as the mounting tube 21 where it is located rotates, and hits the brush roller body 10. In this way, when the brush roller body 10 rotates relative to the housing, a centrifugal force is generated to throw the moving member 30 towards the position of the movement channel 211 close to the brush roller body 10, that is, the position with the opening. When the brush roller body 10 rotates to a position where the extension direction of one or some of the mounting tubes 21 is parallel to the direction of gravity, the moving member 30 moves directly to the opening under the combined action of gravity and centrifugal force and hits the cavity wall on the side of the brush roller body 10 facing the mounting cavity 11, applying a pressing force to the brush roller body 10. Thus, when cleaning the ground, the pressing force of the brush roller 100 on the ground is significantly increased, and dirt can be easily scrubbed off the ground, with high cleaning efficiency and good floor washing effect.

[0058] According to another aspect of the present application, a floor washer is further provided, including the floor brush assembly provided in the above embodiment. In this way, when the floor washer is working, the pressing force of the brush roller 100 of the floor brush assembly on the ground is significantly increased, and dirt can be easily scrubbed off the ground, making the floor washer have high cleaning efficiency and good floor washing effect.

[0059] Specifically, when the floor washer is working, the brush roller 100 of the brush roller assembly is in close contact with the ground. When a part of the mounting tubes 21 rotate to be parallel to the direction of gravity, due to the influence of the self-gravity of the moving member 30, the moving member 30 falls from the high point of the bracket 20, generating an impact and vibration on the brush roller body 10. At the same time, due to the high-speed rotation of the brush roller body 10, the moving member 30 will also generate a certain centrifugal force. Finally, the brush roller body 10 will be subjected to the superposition of impact vibration and centrifugal force, significantly enhancing the pressing force of the brush roller body 10 on the ground. Compared with simply increasing the weight of the brush roller body 10 (for example, setting the brush roller body 10 as solid, to achieve the same pressing force, the volume needs to be made larger, such as adding a counterweight block, the cost is higher), the floor washer provided by the present application has better cleaning effect and performance, and lower cost.

[0060] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0061] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
