Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a roller brush, a roller brush assembly and a cleaning equipment. Background Art

[0002] In recent years, with the improvement of people's living standards, home cleaning has gradually entered the era of automation and intelligence. The cleaning equipment that has emerged, such as sweeping robots, floor scrubbers, vacuum cleaners, etc., can liberate people from home cleaning work, effectively reduce people's workload in home cleaning, and alleviate people's fatigue during home cleaning.

[0003] Usually, a cleaning device is provided with a roller brush for cleaning, and both ends of the roller brush are connected to the housing of the cleaning device, and the floor can be cleaned by the rotation of the roller brush. However, the roller brush in the prior art is not easy to remove hair, which causes the problem that the roller brush is easy to be entangled with hair. Utility Model Content

[0004] The embodiments of the present application provide a roller brush, a roller brush assembly and a cleaning device to solve the problem that the existing roller brushes are difficult to remove hair and are prone to hair entanglement.

[0005] The first aspect of the present application provides a roller brush, comprising a roller brush body, the roller brush body comprising a fixed end and a free end arranged along the axial direction, the fixed end being used to connect with the cleaning device. The two ends of the first cleaning member extend toward the fixed end and the free end of the roller brush body respectively, a plurality of the first cleaning members are arranged at intervals on the outer peripheral wall of the roller brush body, and the first cleaning member is a rubber brush.

[0006] By providing the roller brush body with a fixed end and a free end, so that one end of the roller brush is connected to the cleaning device and the other end is suspended, it is convenient for hair and other garbage to fall off from the free end of the roller brush body, so that the roller brush is easier to remove hair, thereby avoiding the problem of hair entanglement. By providing the first cleaning member, and setting the first cleaning member as a rubber brush, the ability to beat the ground can be improved, especially for the improvement of the beating ability of soft ground such as carpets, so that the dust on soft ground such as carpets can be easier to clean, thereby improving the cleaning ability of the roller brush.

[0007] In a possible implementation, the roller brush further includes a second cleaning member, wherein two ends of the second cleaning member extend toward the fixed end and the free end of the roller brush body respectively, and a plurality of the second cleaning members are arranged at intervals on the outer peripheral wall of the roller brush body. In the radial direction of the roller brush body, the height of the first cleaning member is greater than the height of the second cleaning member.

[0008] By setting a second cleaning member, and setting the height of the first cleaning member in the radial direction of the roller brush body to be greater than the height of the second cleaning member in the radial direction of the roller brush body. In this way, when cleaning hard floors, only the first cleaning member with a larger height contacts the ground for cleaning, thereby reducing noise while ensuring the cleaning effect. When the cleaning device cleans soft floors such as carpets, the cleaning device will sink on the carpet, and the interference between the roller brush and the carpet will increase. The first cleaning member and the second cleaning member will contact the carpet together for rotation and beating, and dust will be peeled off the carpet to improve the cleaning effect. In addition, a space that can accommodate large particles of garbage can be formed between two adjacent first cleaning members, the roller brush body and the second cleaning member, thereby improving the handling effect of large particles of garbage and improving the cleaning ability.

[0009] In a possible implementation manner, the second cleaning member is a rubber brush.

[0010] By configuring the second cleaning member as a rubber brush, the friction between the second cleaning member and a soft floor such as a carpet can be reduced, and the cleaning speed of the cleaning device can be increased. In a possible implementation, the second cleaning member is spaced apart from the first cleaning member.

[0011] In a possible implementation manner, the second cleaning member is spaced apart from the first cleaning member.

[0012] By arranging the second cleaning member and the first cleaning member at intervals, a space for accommodating large particles of garbage can be formed between two adjacent first cleaning members, the roller brush body and the second cleaning member, thereby improving the carrying effect of large particles of garbage and enhancing the cleaning ability.

[0013] In a possible implementation manner, at least one second cleaning member is disposed between two adjacent first cleaning members.

[0014] By arranging at least one second cleaning member between two adjacent first cleaning members, the first cleaning members and the second cleaning members can be arranged alternately, which can improve the aesthetics of the roller brush. In addition, by arranging the first cleaning member and the second cleaning member alternately, the roller brush can be used in a rotating process, and the outer periphery of the roller brush can beat the ground with a relatively balanced force, so that the roller brush can clean the positions it passes through to a substantially equal degree, thereby preventing the problem of some areas being relatively clean and some areas being unclean, and improving the cleaning effect.

[0015] In a possible implementation manner, the hardness of the second cleaning member is greater than the hardness of the first cleaning member.

[0016] By setting the hardness of the second cleaning member to be greater than that of the first cleaning member, that is, the hardness of the first cleaning member is smaller, especially when the second cleaning member is a rubber brush, the noise of the cleaning device can be reduced. In addition, when the cleaning device cleans soft surfaces such as carpets, the cleaning device will sink on the carpet. The soft first cleaning member can reduce the resistance of soft surfaces such as carpets to the roller brush, making it easier to move the cleaning device and improving the cleaning efficiency.

[0017] In a possible implementation manner, the thickness of the second cleaning member is greater than the thickness of the first cleaning member.

[0018] By setting the thickness of the second cleaning member to be greater than that of the first cleaning member, the first cleaning member is made softer than the second cleaning member.

[0019] In a possible implementation, the first cleaning member and the second cleaning member are spirally wound on the outer peripheral wall of the roller brush body in the same direction. The first cleaning member includes a first end and a second end, the first end of the first cleaning member is close to the fixed end, the second end of the first cleaning member is close to the free end, and the rotation angle from the first end of the first cleaning member to the second end of the first cleaning member is between 130° and 150°. And / or, the second cleaning member includes a first end and a second end, the first end of the second cleaning member is close to the fixed end, the second end of the second cleaning member is close to the free end, and the rotation angle from the first end of the second cleaning member to the second end of the second cleaning member is between 130° and 150°.

[0020] By spirally winding the first cleaning member and the second cleaning member on the outer peripheral wall of the roller brush body in the same direction, hair and other garbage can move toward the free end of the roller brush body along the spiral direction of the first cleaning member and the second cleaning member, and this can reduce the resistance of hair and other garbage when they gather toward the free end of the roller brush body as the roller brush rotates, thereby facilitating hair removal.

[0021] In a possible implementation manner, the first cleaning member and the second cleaning member are arranged in parallel.

[0022] By arranging the first cleaning member and the second cleaning member parallel to each other, the aesthetics of the roller brush can be improved.

[0023] In a possible implementation, the number of the first cleaning members is 3-6, and / or the number of the second cleaning members is 3-6.

[0024] In a possible implementation, a dimension of one end of the roller brush located at the fixed end in the radial direction of the roller brush body is greater than a dimension of one end of the roller brush located at the free end in the radial direction of the roller brush body.

[0025] By setting the size of the free end of the roller brush smaller than that of the fixed end of the roller brush, the resistance of hair and other debris to the free end as the roller brush rotates can be reduced, thereby improving the cleaning efficiency and making it easier to remove hair and other debris from the roller brush and suck them into the dust box.

[0026] In a possible implementation, the roller brush includes a transition section. The transition section is disposed close to the free end. The radial dimension of the end of the transition section facing the fixed end in the roller brush body is greater than the radial dimension of the end of the transition section facing the free end in the roller brush body.

[0027] By setting the transition section, the cross-section of the free end of the roller brush can be made smaller than that of the fixed end, and specifically can be conical, which can reduce the resistance to depilation and thus improve the depilatory ability of the roller brush.

[0029] By setting the ratio of the first length to the second length between 0.1-0.25, the size of the roller brush can be smaller only in the transition section, so that the roller brush located between the end of the transition section away from the free end of the roller brush body and the fixed end of the roller brush can be a cylindrical structure. This part of the cylindrical structure has the same distance from the ground to be cleaned. Compared with setting the entire roller brush to a conical structure, it can ensure that more roller brush is in contact with the ground to be cleaned, thereby improving the cleaning effect.

[0030] In a possible implementation manner, in the direction from the fixed end to the free end, the size of the transition section in the radial direction of the roller brush body gradually decreases.

[0124] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0125] The roller brush, roller brush assembly and cleaning device provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0126] Figure 1 A schematic structural diagram of a roller brush 100 provided in an embodiment of the present application.

[0127] The present application embodiment provides a roller brush 100, such as Figure 1 As shown, the roller brush 100 may include a roller brush body 10, the roller brush body 10 includes a fixed end 11 and a free end 12 arranged in the axial direction, and the fixed end 11 can be used to connect with a cleaning device. The two ends of the first cleaning member 31 extend toward the fixed end 11 and the free end 12 of the roller brush body 10 respectively, and a plurality of first cleaning members 31 are arranged at intervals on the outer peripheral wall of the roller brush body 10, and the first cleaning members 31 are rubber brushes.

[0128] By providing the roller brush body 10 with a fixed end 11 and a free end 12, one end of the roller brush 100 is connected to the cleaning device, and the other end is suspended, so that hair and other garbage can be easily removed from the free end 12 of the roller brush body 10, so that the roller brush 100 is easier to remove hair, thereby avoiding the problem of hair entanglement. By providing the first cleaning member 31, and setting the first cleaning member 31 as a rubber brush, the ability to beat the ground can be improved, especially for the improvement of the beating ability of soft ground such as carpets, so that the dust on soft ground such as carpets can be more easily cleaned, thereby improving the cleaning ability of the roller brush 100.

[0129] Continue to see Figure 1 As shown, the roller brush 100 may further include a second cleaning member 32, wherein two ends of the second cleaning member 32 extend toward the fixed end 11 and the free end 12 of the roller brush body 10, respectively, and a plurality of second cleaning members 32 are arranged at intervals on the outer peripheral wall of the roller brush body 10. In the radial direction of the roller brush body 10, the height of the first cleaning member 31 is greater than the height of the second cleaning member 32.

[0130] By setting the second cleaning member 32, and setting the height of the first cleaning member 31 in the radial direction of the roller brush body 10 to be greater than the height of the second cleaning member 32 in the radial direction of the roller brush body 10. In this way, when cleaning hard ground, only the first cleaning member 31 with a larger height contacts the ground for cleaning, and the noise is reduced under the premise of ensuring the cleaning effect. When the cleaning device cleans soft ground such as carpet, the cleaning device will sink on the carpet, the interference between the roller brush 100 and the carpet becomes larger, and the first cleaning member 31 and the second cleaning member 32 contact the carpet together for rotating and beating, and dust is peeled off the carpet to improve the cleaning effect. In addition, a space that can accommodate large particles of garbage can be formed between two adjacent first cleaning members 31, the roller brush body 10 and the second cleaning member 32, which can improve the handling effect of large particles of garbage and improve the cleaning ability.

[0131] Of course, in other embodiments, the height of the first cleaning member 31 in the radial direction of the roller brush body 10 may be set to be smaller than the height of the second cleaning member 32 in the radial direction of the roller brush body 10. In the embodiment of the present application, the height of the first cleaning member 31 in the radial direction of the roller brush body 10 and the height of the second cleaning member 32 in the radial direction of the roller brush body 10 are not limited.

[0132] For example, Figure 1 As shown, the second cleaning member 32 may be a rubber brush. By configuring the second cleaning member 32 as a rubber brush, the friction between the second cleaning member 32 and a soft floor such as a carpet can be reduced, and the cleaning speed of the cleaning device can be increased.

[0133] Figure 2 A schematic diagram of the cross-sectional structure of a roller brush provided in an embodiment of the present application.

[0134] See also Figure 2 As shown, the second cleaning member 32 and the first cleaning member 31 may be arranged at intervals. Exemplarily, at least one second cleaning member 32 is arranged between two adjacent first cleaning members 31. For example, one second cleaning member 32 may be arranged between two adjacent first cleaning members 31, or two second cleaning members 32 may be arranged.

[0135] It should be noted that the number of second cleaning members 32 provided between any two adjacent first cleaning members 31 may be the same or different. In the embodiment of the present application, the number of second cleaning members 32 provided between any two adjacent first cleaning members 31 is not further limited.

[0136] By spacing the second cleaning member 32 and the first cleaning member 31, a space a for accommodating large particles of garbage can be formed between two adjacent first cleaning members 31, the roller brush body 10 and the second cleaning member 32, thereby improving the carrying effect of large particles of garbage and enhancing the cleaning ability.

[0137] By arranging at least one second cleaning member 32 between two adjacent first cleaning members 31, the first cleaning members 31 and the second cleaning members 32 can be arranged alternately, which can improve the aesthetics of the roller brush 100. In addition, by arranging the first cleaning members 31 and the second cleaning members 32 alternately, the roller brush 100 can be used in a rotating process, and the outer periphery of the roller brush 100 can have a relatively balanced beating force on the ground, thereby making the roller brush 100 have a substantially equal degree of cleaning of the positions it passes through, thereby preventing the problem of some areas being relatively clean and some areas being unclean, and improving the cleaning effect.

[0138] like Figure 2 As shown, in some embodiments, the first cleaning member 31 and the second cleaning member 32 of the roller brush 100 can form a hollow cylindrical structure 33 that matches the shape of the roller brush body 10, that is, the first cleaning member 31 and the second cleaning member 32 are an integrated structure, which can facilitate the processing of the first cleaning member 31 and the second cleaning member 32 and reduce the processing cost.

[0139] Exemplarily, the hollow cylindrical structure 33 provided with the first cleaning member 31 and the second cleaning member 32 can be sleeved on the outside of the roller brush body 10 and fixedly connected to the roller brush body 10 so that the first cleaning member 31 and the second cleaning member 32 are provided on the outer peripheral side of the roller brush body 10.

[0140] Of course, in some other embodiments, the first cleaning member 31 and the second cleaning member 32 can also be set as a split structure. Accordingly, an installation position for installing the first cleaning member 31 and the second cleaning member 32 can be set on the roller brush body 10, and the first cleaning member 31 and the second cleaning member 32 can be fixed to the outer peripheral wall of the roller brush body 10 by plugging, snapping, gluing, etc.

[0141] In a possible implementation, the hardness of the second cleaning member 32 is greater than the hardness of the first cleaning member 31 .

[0142] By setting the hardness of the second cleaning member 32 to be greater than that of the first cleaning member 31, that is, the hardness of the first cleaning member 31 is smaller, the noise of the cleaning device can be reduced. In addition, when the cleaning device cleans a soft floor such as a carpet, the cleaning device will sink on the carpet. The soft first cleaning member 31 can reduce the resistance of the soft surface such as the carpet to the roller brush 100, making it easier to move the cleaning device and improving the cleaning efficiency.

[0143] Exemplarily, the thickness of the second cleaning member 32 is greater than that of the first cleaning member 31. By setting the thickness of the second cleaning member 32 to be greater than that of the first cleaning member 31, the first cleaning member 31 is made softer than the second cleaning member 32.

[0144] It should be noted that, in some other embodiments, the first cleaning member 31 and the second cleaning member 32 can be made of different materials so that the hardness of the first cleaning member 31 is smaller than that of the second cleaning member 32. For example, the first cleaning member 31 can be made of silicone and the second cleaning member 32 can be made of rubber. In the embodiments of the present application, the materials of the first cleaning member 31 and the second cleaning member 32 are not further limited.

[0145] Continue to see Figure 1 As shown, the first cleaning member 31 and the second cleaning member 32 are spirally wound along the same direction on the outer peripheral wall of the roller brush body 10. The spiral winding direction of the first cleaning member 31 and the second cleaning member 32 can be clockwise or counterclockwise. In the embodiment of the present application, the spiral winding direction of the first cleaning member 31 and the second cleaning member 32 is not further limited.

[0146] The first cleaning member 31 includes a first end and a second end, the first end of the first cleaning member 31 is close to the fixed end 11 of the roller brush body 10, the second end of the first cleaning member 31 is close to the free end 12 of the roller brush body 10, and the rotation angle α from the first end of the first cleaning member 31 to the second end of the first cleaning member 31 is 1 Between 130° and 150°, see Figure 3 As shown, Figure 3 FIG. 2 is a schematic structural diagram showing only one first cleaning member 31 disposed on the roller brush body 10 .

[0147] The second cleaning member 32 also includes a first end and a second end. The first end of the second cleaning member 32 is close to the fixed end 11 of the roller brush body 10, and the second end of the second cleaning member 32 is close to the free end 12 of the roller brush body 10. The rotation angle α from the first end of the second cleaning member 32 to the second end of the second cleaning member 32 is 2 Between 130° and 150°, see Figure 4 As shown, Figure 4 FIG. 2 shows a schematic structural diagram of a roller brush body 10 in which only one second cleaning member 32 is provided.

[0148] It should be noted that the rotation angles of the first cleaning member 31 and the second cleaning member 32 can be the same, for example, both can be 140°, 145°, etc. In other words, the first cleaning member 31 and the second cleaning member 32 are arranged in parallel. By arranging the first cleaning member 31 and the second cleaning member 32 in parallel with each other, the aesthetics of the roller brush 100 can be improved.

[0149] Of course, in other embodiments, the rotation angles of the first cleaning member 31 and the second cleaning member 32 may also be different. For example, the spiral angle of the first cleaning member 31 is 140°, and the spiral angle of the second cleaning member 32 is 145°, etc. In the embodiment of the present application, the rotation angles of the first cleaning member 31 and the second cleaning member 32 are not further limited.

[0150] By spirally winding the first cleaning member 31 and the second cleaning member 32 along the same direction around the outer peripheral wall of the roller brush body 10, hair and other garbage can move toward the free end 12 of the roller brush body 10 along the spiral direction of the first cleaning member 31 and the second cleaning member 32. In this way, the resistance of hair and other garbage gathering toward the free end 12 of the roller brush body 10 as the roller brush 100 rotates can be reduced, which facilitates hair removal.

[0151] It should be noted that the number of the first cleaning members 31 may be the same or different. When the number of the first cleaning members 31 and the second cleaning members 32 is the same, the first cleaning members 31 and the second cleaning members 32 may be alternately arranged on the outer peripheral wall of the roller brush body 10, so that the roller brush 100 may have a centrally symmetrical structure, thereby improving the aesthetics of the roller brush 100 and improving the balance of the cleaning ability of the roller brush 100.

[0152] When the number of the first cleaning member 31 and the second cleaning member 32 are different, the design flexibility of the roller brush 100 can be improved. For example, when the roller brush 100 is suitable for a softer and thicker carpet, the number of the first cleaning member 31 can be set to be smaller, so that a larger space can be provided for large particles of garbage, making it easier to clean up the large particles of garbage. In the embodiment of the present application, the number of the first cleaning member 31 and the number of the second cleaning member 32 are not further limited.

[0153] Exemplarily, the number of the first cleaning members 31 may be 3-6. The number of the second cleaning members 32 may be 3-6. For example, the number of the first cleaning members 31 and the second cleaning members 32 are both 3, 4, 5 or 6. Alternatively, the number of the first cleaning members 31 is 3, the number of the second cleaning members 32 is 6, and so on.

[0154] It should be noted that the number of the first cleaning member 31 and the second cleaning member 32 on the roller brush 100 is related to the size of the roller brush body 10. For example, when the outer diameter of the roller brush 100 is large, a larger number of the first cleaning member 31 and the second cleaning member 32 are required. When the outer diameter of the roller brush 100 is small, a smaller number of the first cleaning member 31 and the second cleaning member 32 are required. Therefore, in the embodiment of the present application, the number of the first cleaning member 31 and the second cleaning member 32 is not further limited.

[0155] Continue to see Figure 1As shown, the radial dimension of the roller brush body 10 at one end of the roller brush 100 located at the fixed end 11 is greater than the radial dimension of the roller brush body 10 at one end of the roller brush 100 located at the free end 12 .

[0156] By setting the size of the free end 12 of the roller brush 100 to be smaller than the size of the fixed end 11 of the roller brush 100, the resistance of hair and other debris when gathering toward the free end 12 as the roller brush 100 rotates can be reduced, thereby improving the cleaning efficiency and making it easier to separate hair and other debris from the roller brush 100 and suck them into the dust box.

[0157] Exemplarily, the roller brush 100 includes a transition section 20. The transition section 20 is disposed near the free end 12. The radial dimension of the end of the transition section 20 facing the fixed end 11 in the roller brush body 10 is greater than the radial dimension of the end of the transition section 20 facing the free end 12 in the roller brush body 10.

[0158] It should be noted that since the outer contour dimension of the end of the transition section 20 close to the free end 12 is smaller, the provision of the transition section 20 can make the cross-section of the free end 12 of the roller brush 100 smaller than that of the fixed end 11. Specifically, it can be a conical structure, which can reduce the resistance to hair removal from the free end 12 of the roller brush 100, thereby improving the hair removal ability of the roller brush 100.

[0159] For the convenience of description, the axial direction of the roller brush body 10 is taken as the x direction.

[0160] like Figure 1 As shown, the transition section 20 can be a conical structure. Specifically, in the direction from the fixed end 11 to the free end 12 of the roller brush body 10, the size of the transition section 20 in the radial direction of the roller brush body 10 gradually decreases. By setting the size of the transition section 20 in the radial direction of the roller brush body 10 to gradually decrease in the direction from the fixed end 11 to the free end 12, the free end 12 of the roller brush 100 can be formed into a conical structure, which can reduce the resistance of hair and other garbage when gathering toward the free end 12 as the roller brush 100 rotates, thereby improving the cleaning efficiency.

[0161] In the axial direction (x direction) of the roller brush body 10, the length of the transition section 20 is a first length L1, and the length of the roller brush body 10 is a second length L2. The ratio of the first length L1 to the second length L2 is between 0.1-0.25.

[0162] Exemplarily, the ratio of the transition section 20 to the entire roller brush body 10 can be one-fifth, one-sixth, one-seventh, one-eighth or one-ninth, etc. In the embodiment of the present application, the ratio of the length of the transition section 20 in the x direction to the length of the roller brush body 10 is not further limited.

[0163] By setting the ratio of the first length to the second length between 0.1-0.25, the roller brush 100 can be smaller in size only in the transition section 20, so that the roller brush 100 located between the end of the transition section 20 away from the free end 12 of the roller brush body 10 and the fixed end 11 of the roller brush 100 can be a cylindrical structure. This part of the cylindrical structure has the same distance from the ground to be cleaned. Compared with setting the roller brush 100 as a conical structure as a whole, it can ensure that more of the roller brush 100 is in contact with the ground to be cleaned, thereby improving the cleaning effect.

[0164] It should be noted that, since the roller brush 100 includes a roller brush body 10 and a first cleaning member 31 and a second cleaning member 32 disposed outside the roller brush body 10, the free end 12 of the roller brush body 10 can be set to a conical structure to form a conical transition section 20, or the first cleaning member 31 and the second cleaning member 32 are located at one end of the free end 12 of the roller brush body 10 and are set to be smaller in size, so that the conical transition section 20 can also be formed. Alternatively, the free end 12 of the roller brush body 10 is set to a conical structure, and the first cleaning member 31 and the second cleaning member 32 are located at one end of the free end 12 of the roller brush body 10 and are set to be smaller in size, so that the conical transition section 20 can also be formed.

[0165] like Figure 5 As shown, in the direction from the fixed end 11 to the free end 12, the size of the roller brush body 10 located on the transition section 20 in the radial direction of the roller brush body 10 gradually decreases. The size of the first cleaning member 31 located on the transition section 20 in the radial direction of the roller brush body 10 gradually decreases. The size of the second cleaning member 32 located on the transition section 20 in the radial direction of the roller brush body 10 gradually decreases.

[0166] By gradually reducing the radial size of the roller brush body 10 located on the transition section 20 in the direction from the fixed end 11 to the free end 12, gradually reducing the radial size of the roller brush body 10 of the first cleaning member 31, and gradually reducing the radial size of the roller brush body 10 of the second cleaning member 32, the free end 12 of the roller brush 100 can be formed into a conical structure, which can reduce the resistance of hair and other garbage when it gathers toward the free end 12 as the roller brush 100 rotates, thereby improving the cleaning efficiency.

[0167] In some embodiments, Figure 6 As shown, the angle θ between the generatrix of the conical structure formed by the outer contour of the transition section 20 and the central axis of the roller brush body 10 can be between 0-20°. For example, it can be 15°, 16°, 17°, etc.

[0168] Exemplarily, the free end 12 of the roller brush body 10 is a conical structure, and the angle between the generatrix of the conical structure and the central axis of the roller brush body 10 is between 0-20°, for example, 15°, 16°, 17°, etc.

[0169] Exemplarily, in the radial direction of the roller brush body 10, the first cleaning member 31 and / or the second cleaning member 32 located in the transition section 20 are away from the roller brush body 10 at one end, and gradually tilt toward the roller brush body 10 along the direction from the fixed end 11 to the free end 12 of the roller brush body 10, wherein from the end of the transition section 20 close to the fixed end 11 of the roller brush body 10 to the end of the transition section 20 close to the free end 12 of the roller brush 100, the first cleaning member 31 and / or the second cleaning member 32 gradually tilt toward the roller brush body 10 at 0-20°. For example, it may be 15°, 16°, 17°, etc.

[0170] It should be noted that the taper of the conical structure formed by the outer contour of the transition section 20 can be set according to specific circumstances. In the embodiment of the present application, the taper of the conical structure formed by the outer contour of the transition section 20 is not further limited.

[0171] It should be noted that since the height of the second cleaning member 32 in the axial direction of the roller brush body 10 is relatively small, in some embodiments, only the height of the end of the first cleaning member 31 close to the free end 12 can be set to be relatively small. In this way, the free end 12 of the roller brush 100 can also form a conical structure, thereby achieving the effect of convenient hair removal.

[0172] Of course, in other embodiments, the transition section 20 may not be provided, so that the entire roller brush 100 has a cylindrical structure, which can make the distance between the entire roller brush 100 and the cleaned ground the same, thereby improving the cleaning effect of the roller brush 100. Therefore, in the embodiment of the present application, the specific structure of the transition section 20 is not further limited.

[0173] Continue to see Figure 5 As shown, the roller brush 100 may further include a fixing component 40. The fixing component 40 is detachably connected to the fixing end 11 of the roller brush body 10. The fixing component 40 is used to connect the roller brush 100 to a cleaning device. Exemplarily, when the roller brush 100 is connected to the cleaning device, the fixing component 40 needs to be connected to the driving structure 240 of the cleaning device so that the cleaning device can drive the roller brush 100 to rotate through the fixing component 40, thereby achieving a cleaning function.

[0174] By setting up a fixing component 40, the roller brush 100 can be connected to the cleaning device, and by detachably connecting the fixing component 40 to the fixed end 11 of the roller brush body 10, the fixing component 40 can be removed from the roller brush body 10 to clean the garbage in the gap between the roller brush body 10 and the fixing component 40, making it convenient for users to clean the roller brush 100.

[0175] In some embodiments, in combination Figure 5 and Figure 7 As shown, the fixing assembly 40 may include a first connecting member 41 and a second connecting member 42. The first connecting member 41 is rotatably connected to the roller brush body 10, and the first connecting member 41 is used to be fixedly connected to the cleaning device. The second connecting member 42 is detachably connected to the roller brush body 10, and the second connecting member 42 is used to drive the roller brush body 10 to rotate relative to the first connecting member 41.

[0176] Exemplarily, the first connecting member 41 is sleeved on the outer side of the fixed end 11 of the roller brush body 10 and is rotatably connected to the roller brush body 10 .

[0177] By providing the fixing assembly 40 with a first connecting member 41, the first connecting member 41 is fixedly connected to the cleaning device, and by rotatably connecting the first cleaning member 31 to the roller brush body 10, the roller brush body 10 can rotate relative to the first cleaning member 31. By providing a second connecting member 42, one end of the second connecting member 42 is connected to the driving structure 240 of the cleaning device, and the other end is detachably connected to the roller brush body 10, so that the second cleaning member 32 can drive the roller brush body 10 to rotate relative to the first connecting member 41. So that the roller brush 100 can perform cleaning work.

[0178] like Figure 5 As shown, the first connecting member 41 may include a fixing portion 411. The fixing portion 411 extends from the outer side of the first connecting member 41 along the axial direction (x direction) of the roller brush body 10 toward the direction close to the free end 12.

[0179] When the roller brush 100 is connected to the cleaning device, it can be fixedly connected to the cleaning device through the fixing portion 411, such as Figure 8 As shown, exemplarily, the roller brush assembly 1000 using the roller brush 100 may include a shell 200, and the shell 200 may include a first shell 210 and a second shell 220, the first shell 210 and the second shell 220 are arranged relative to each other and form a accommodating cavity 230, the roller brush 100 is arranged in the accommodating cavity 230, and the first shell 210 and the second shell 220 are detachably connected.

[0180] Exemplarily, the roller brush 100 is located between the first shell 210 and the second shell 220 . When the first shell 210 and the second shell 220 are separated, the roller brush 100 can be removed from the shell 200 of the roller brush assembly 1000 .

[0181] In a possible implementation, the fixing portion 411 of the roller brush 100 is sandwiched between the first shell 210 and the second shell 220, that is, when the first shell 210 and the second shell 220 are connected, the fixing portion 411 of the roller brush 100 can be sandwiched between the first shell 210 and the second shell 220, and the roller brush 100 is fixed on the roller brush assembly 1000. Among them, the first shell 210 and the second shell 220 can be provided with an assembly space for assembling the fixing portion 411, and when the roller brush 100 is arranged on the shell 200, the fixing portion 411 is just located in the assembly space. By arranging the fixing portion 411 on the first connecting member 41, the first connecting member 41 is fixedly connected to the cleaning device through the fixing portion 411. By arranging the fixing portion 411 from the outside of the first connecting member 41 along the axial direction of the roller brush body 10, extending in the direction close to the free end 12, the connection length of the first connecting member 41 and the cleaning device is increased, thereby improving the connection stability of the roller brush 100 and the cleaning device. When the roller brush 100 rotates, the roller brush 100 can be prevented from shaking from the right end.

[0182] It should be noted that, in the embodiment of the present application, the length of the fixing portion 411 in the x direction is related to the length of the roller brush 100 in the x direction. For example, when the length of the roller brush 100 in the x direction is large, the length of the fixing portion 411 in the x direction is also large. In other words, the length of the fixing portion 411 in the x direction can be determined according to the length of the roller brush 100 in the x direction. Therefore, in the embodiment of the present application, the length of the fixing portion 411 in the x direction is not limited.

[0183] Of course, in some other embodiments, the fixing portion 411 may not be provided, and the first connecting member 41 may be directly connected to the cleaning device through the end or outer side. In the embodiment of the present application, the specific structure of the first connecting member 41 is not further limited.

[0184] Continue to see Figure 7 As shown, a matching portion 13 matching with the second connecting member 42 is provided on the roller brush body 10, and the second connecting member 42 is detachably connected to the matching portion 13. The matching portion 13 extends from the inside of the roller brush body 10 along the axial direction of the roller brush body 10 to the outside of the fixed end 11. The second connecting member 42 is detachably connected to the end of the matching portion 13 away from the free end 12.

[0185] By setting the matching portion 13 so as to match and connect with the second connecting member 42, it is more convenient to disassemble the fixing assembly 40. The efficiency of the user in maintaining the roller brush 100 is improved. By setting the matching portion 13 to extend beyond the fixed end 11, it is convenient to connect with the second connecting member 42. And it is convenient to connect with the driving structure 240 of the cleaning device through the second connecting member 42. Of course, in some embodiments, the matching portion 13 can also be set to other structures. In the embodiment of the present application, the specific structure of the matching portion 13 is not further limited.

[0186] It should be noted that the matching portion 13 and the second connecting member 42 can be detachably connected by means of threaded connection, snap-fit ​​connection, etc.

[0187] Exemplarily, the second connecting member 42 is provided with a first thread, and the matching portion 13 is provided with a second thread matching with the first thread. The second connecting member 42 and the matching portion 13 are detachably connected via the first thread and the second thread.

[0188] By connecting the second connecting member 42 and the matching portion 13 by threading, the structure of the second connecting member 42 and the matching portion 13 can be simplified, thereby reducing the cost. In addition, the threaded connection facilitates disassembly, which can reduce the difficulty of disassembling the second connecting member 42 and the roller brush body 10.

[0189] Exemplarily, the second connecting member 42 can be a structure such as a nut, a threaded hole with a first thread is provided in the second connecting member 42, and a second thread that matches the second connecting member 42 is provided on the matching portion 13. During assembly, the second connecting member 42 and the matching portion 13 can be detachably connected.

[0190] Among them, other structures can also be arranged between the roller brush body 10 and the matching portion 13, such as Figure 7 As shown, a third connecting member 44 is provided on the outer side of the matching portion 13, and the third connecting member 44 is sleeved on the outer side of the matching portion 13 and fixedly connected to the matching portion 13, and the outer side of the third connecting member 44 is fixedly connected to the roller brush body 10. A gasket 45 can also be provided between the third connecting member 44 and the roller brush body 10, so that the third connecting member 44 can be fixedly connected to the roller brush body 10. By providing the third connecting member 44 and the gasket 45, the strength of the matching portion 13 can be increased, thereby improving the strength of the roller brush body 10, ensuring the stability of the roller brush 100, and extending the service life.

[0191] Of course, in some embodiments, the third connecting member 44 and the gasket 45 may not be provided. In the embodiment of the present application, other structures between the roller brush body 10 and the matching portion 13 are not further limited.

[0192] In some other embodiments, the second connecting member 42 and the matching portion 13 may be configured as other structures. Fig. 9 As shown, the second connecting member 42 can be provided with a screw structure, and the first thread is an external thread provided on the outside of the screw. The matching portion 13 is a hole-shaped structure provided in the roller brush body 10, and the second thread is an internal thread provided on the inner wall of the hole-shaped structure. The screw of the second connecting member 42 is inserted into the matching portion 13 and is detachably connected to the matching portion 13.

[0193] By configuring the second connecting member 42 to include a screw and configuring the matching portion 13 to be a hole-shaped structure located inside the roller brush body 10, the structure of the roller brush body 10 can be simplified, the processing difficulty can be reduced, and the cost can be reduced. When the second connecting member 42 is screwed into the matching portion 13, the strength of the roller brush body 10 can be increased, the shaking of the roller brush 100 during cleaning operation can be reduced, and the stability of the roller brush 100 can be improved.

[0194] It should be noted that, in the embodiment of the present application, the length of the screw of the second connecting member 42 in the x direction can be set to be at least greater than one third of the length of the roller brush body 10 in the x direction. In other words, the length of the screw of the second connecting member 42 in the x direction is set to be larger. In this way, the structural strength of the roller brush body 10 can be improved, thereby extending the service life of the roller brush 100.

[0195] For example, the length of the screw of the second connecting member 42 in the x-direction may be the same as the length of the roller brush body 10 in the x-direction. In other embodiments, the length of the screw of the second connecting member 42 in the x-direction may be half of the length of the roller brush body 10 in the x-direction. In the embodiment of the present application, the length of the screw of the second connecting member 42 in the x-direction is not limited.

[0196] It should be noted that the screwing direction of the first thread and the second thread is opposite to the rotation direction of the roller brush 100 when it is working, so as to prevent the second connecting member 42 and the roller brush body 10 from being accidentally separated when the roller brush 100 is working.

[0197] The above describes an embodiment in which the second connecting member 42 and the roller brush body 10 are connected by threads. Of course, in other embodiments, the second connecting member 42 and the roller brush body 10 may be detachably connected by other means.

[0198] For example, Fig.10 As shown, the second connecting member 42 is provided with a first engaging portion 421, and the matching portion 13 is provided with a second engaging portion (not shown in the figure) that matches the first engaging portion 421. The second connecting member 42 and the matching portion 13 are detachably connected via the first engaging portion 421 and the second engaging portion.

[0199] Exemplarily, the matching portion 13 extends from the inside of the roller brush body 10 along the axial direction of the roller brush body 10 to the outside of the fixed end 11. The second connecting member 42 is detachably connected to the end of the matching portion 13 away from the free end 12. A through hole is provided inside the second connecting member 42, a protrusion is provided along the circumference of the through hole inside the through hole, and a groove matching the protrusion is provided on the circumference of the matching portion 13. During assembly, the second connecting member 42 and the matching portion 13 can be snap-connected. Of course, in other embodiments, the protrusion can also be provided on the matching portion 13, and the groove can be provided on the second connecting member 42.

[0200] By connecting the second connecting member 42 and the matching portion 13 by snapping, the structure of the second connecting member 42 and the matching portion 13 is simplified, thereby reducing the cost. In addition, the snap connection is easy to disassemble, which can reduce the difficulty of the user to disassemble the fixing component 40 and the roller brush body 10. Moreover, during assembly, only the second cleaning member 32 needs to be plugged in and out, which is simple to operate.

[0201] Continue to see Figure 7 As shown, the fixing assembly 40 further includes a blocking portion 43, which is disposed between the first connecting member 41 and the roller brush body 10. The blocking portion 43 is used to prevent garbage from entering the gap between the first cleaning member 31 and the roller brush body 10.

[0202] For example, the blocking portion 43 may be a fluffy and elastic structure such as an annular terry loop or sponge, so that after the first connecting member 41 and the roller brush body 10 are connected, the blocking portion 43 can fill the gap between the first cleaning member 31 and the roller brush body 10, thereby preventing hair and other garbage from entering the gap between the first cleaning member 31 and the roller brush body 10. This reduces the difficulty of cleaning the roller brush 100 for the user.

[0203] Of course, in some other embodiments, the blocking portion 43 may also be configured as other structures. In the embodiment of the present application, the structure of the blocking portion 43 is not further limited.

[0204] In the implementation of the present application, a roller brush 100 is also provided, which is applied to a cleaning device, and includes a roller brush body 10, wherein the roller brush body 10 includes a fixed end 11 and a free end 12 arranged along the axial direction, and the fixed end 11 is used to connect to the cleaning device. A fixing assembly 40 is also included, and the fixing assembly 40 is detachably connected to the fixed end 11 of the roller brush body 10, and the fixing assembly 40 is used to connect the roller brush 100 to the cleaning device.

[0205] By providing the roller brush body 10 with a fixed end 11 and a free end 12, one end of the roller brush 100 is connected to the cleaning device, and the other end is suspended, so that hair and other garbage can be easily removed from the free end 12 of the roller brush body 10, so that the roller brush 100 is easier to remove hair, thereby avoiding the problem of hair entanglement. By providing a fixing component 40, the roller brush 100 is connected to the cleaning device, and by detachably connecting the fixing component 40 to the fixed end 11 of the roller brush body 10, the fixing component 40 can be removed from the roller brush body 10 to clean the garbage in the gap between the roller brush body 10 and the fixing component 40, so that the user can clean the roller brush 100 conveniently.

[0206] It should be noted that the structure, principle and coordination with other components of the roller brush body 10 and the fixing assembly 40 of the roller brush 100 in the embodiment of the present application are similar to those described above. Figure 1-Figure 10 The fixing assembly 40 is the same as that described in the above embodiment.

For details, please refer to the description of the first cleaning member 31 and the second cleaning member 32 in the above embodiment, which will not be repeated in the embodiment of the present application.

[0208] Of course, in other embodiments, the cleaning component of the roller brush 100 in the embodiment of the present application may also be other structures. Fig.11 As shown, the roller brush body 10 further includes a brush portion 34, wherein a plurality of brush portions 34 are arranged at intervals along the outer periphery of the roller brush body 10. In the axial direction of the roller brush body 10, two ends of the brush portion 34 extend toward the fixed end 11 and the free end 12 of the roller brush body 10, respectively. In the radial direction of the roller brush body 10, one end of the brush portion 34 is fixedly connected to the roller brush body 10, and the other end extends in a direction away from the roller brush body 10.

[0209] By providing the brush portion 34 on the outer periphery of the roller brush body 10, the roller brush 100 can have a cleaning function, and the brush has a stronger cleaning ability for hair and the like, so the cleaning effect of the brush on hair can be improved.

[0210] The above embodiment introduces the specific structure of the roller brush 100.

The cleaning device in the embodiment of the present application, by setting the above roller brush 100, is convenient for hair removal and can prevent hair entanglement. It can also improve the cleaning effect of the roller brush 100 of the cleaning device on soft floors such as carpets, and can reduce the noise when cleaning hard floors. It is also convenient to disassemble the roller brush 100 on the cleaning device, and then it is convenient to clean the roller brush 100, thereby improving the user experience.

[0211] It should be noted that the cleaning device may be a sweeping robot, a floor scrubber, a vacuum cleaner, or other device with a cleaning function. In the embodiments of the present application, the specific structure of the cleaning device is not further described.

[0212] The roller brush assembly 1000 using the roller brush 100 in the above embodiment is described below.

[0213] like Fig.12 As shown, the present application provides a roller brush assembly 1000, including a shell 200 and a roller brush 100 of any of the above-mentioned embodiments. A accommodating chamber 230 is provided in the shell 200, and the roller brush 100 is installed in the accommodating chamber 230 of the shell 200. A dust suction port 211 connected to the accommodating chamber 230 is provided on the shell 200. The dust suction port 211 is used for the cleaning device to apply suction to the accommodating chamber 230, and then the garbage is sucked into the dust box of the cleaning device through the dust suction port 211. The roller brush 100 includes a free end 12 and a fixed end 11, the fixed end 11 of the roller brush 100 is fixedly connected to the shell 200, and the free end 12 of the roller brush 100 is arranged close to the dust suction port 211.

[0214] By providing a housing 200 and providing a receiving chamber 230 in the housing 200, the roller brush 100 can be installed in the housing 200, and the housing 200 has a certain protective effect on the roller brush 100. By providing a dust suction port 211, suction is applied to the receiving chamber 230, so that garbage can be sucked into the dust box of the cleaning device from the dust suction port 211 for centralized processing. By arranging the free end 12 of the roller brush 100 close to the dust suction port 211, garbage that falls off from the free end 12 can be quickly sucked into the dust box, thereby improving the cleaning efficiency.

[0215] like Fig.13As shown, the housing 200 may include a first housing 210 and a second housing 220, the first housing 210 and the second housing 220 are arranged opposite to each other and form a receiving chamber 230, and the roller brush 100 is arranged in the receiving chamber 230. The first housing 210 and the second housing 220 are detachably connected, and a dust suction port 211 is provided on the first housing 210. An opening 221 is provided on the second housing 220, and the dust suction port 211 is communicated with the opening 221, and the opening 221 is used for the roller brush 100 to contact the ground.

[0216] By setting the housing 200 as a first housing 210 and a second housing 220, and detachably connecting the first housing 210 and the second housing 220, the roller brush 100 can be easily disassembled. By setting an opening 221 on the second housing 220, a part of the structure of the roller brush 100 can contact the ground, so that the roller brush 100 can easily clean the ground. By connecting the opening 221 with the dust suction port 211, it is convenient to suck the hair and other garbage sucked from the opening 221 into the dust box of the cleaning device.

[0217] In one possible implementation, a first shielding portion 222 is provided on the second shell 220, and the first shielding portion 222 is arranged on one side of the opening 221 along the axial direction of the roller brush 100, one end of the first shielding portion 222 is connected to the second shell 220, and the other end extends away from the second shell 220 and toward the inner side of the opening 221.

[0218] By setting the first shielding portion 222, when the roller brush assembly 1000 is used, a closed space can be formed at the opening 221, thereby reducing the leakage of suction applied from the suction port 211, improving the dust collection effect of the cleaning device using the roller brush assembly 1000, and further improving the cleaning effect.

[0219] Exemplarily, the first shielding portion 222 includes a plurality of openings 221, wherein in the x direction, the plurality of openings 221 are spaced apart on the first shielding portion 222. This allows the first shielding portion 222 to be easily deformed, so that when cleaning a soft floor such as a carpet, the first shielding portion 222 can be deformed to prevent sinking into the carpet and causing problems such as jamming.

[0220] It should be noted that in the embodiment of the present application, the number of the openings 221 on the first shielding portion 222 is not further limited.

[0221] It should be noted that the first shielding portion 222 may be a soft rubber structure. For example, the material of the first shielding portion 222 may be rubber, silicone, etc. By setting the first shielding portion 222 as a soft rubber structure, when the roller brush assembly 1000 is used to clean a soft floor such as a carpet, the first shielding portion 222 may be prevented from sinking into the carpet and causing the cleaning device to become stuck.

[0222] Of course, in other embodiments, the first shielding portion 222 may be configured as other structures, for example, the first shielding portion 222 may not be configured with the opening 221. In the embodiment of the present application, the structure of the first shielding portion 222 is not further limited.

[0223] In some other embodiments, a second shielding portion 223 is further disposed on the second housing 220. The second shielding portion 223 is disposed opposite to the first shielding portion 222, one end of the second shielding portion 223 is connected to the second housing 220, and the other end of the second shielding portion 223 extends away from the second housing 220 and toward the inside of the opening 221.

[0224] By providing the second shielding portion 223, the airtightness at the opening 221 can be further improved, thereby reducing the leakage of the suction force applied from the suction port 211, improving the dust collection effect of the cleaning device using the roller brush assembly 1000, and further improving the cleaning effect.

[0225] The roller brush assembly 1000 in the above embodiment is provided with a roller brush 100, wherein in the axial direction of the roller brush 100, the length of the roller brush 100 is greater than or equal to the length of the opening 221. In this way, all positions passed by the roller brush assembly 1000 can be cleaned, the cleaning area can be increased, and missed cleaning can be prevented, thereby improving the cleaning efficiency.

[0226] Of course, in other embodiments, there may be more than one roller brush 100. The arrangement positions of the multiple roller brushes 100 may include various situations. The following description will be made by taking the case where there are two roller brushes 100 as an example.

[0227] For example, Fig.14 As shown, the fixed ends 11 of the two roller brushes 100 are located on the same side of the housing 200. The free ends 12 of the two roller brushes 100 are arranged close to the suction port 211. By arranging two roller brushes 100, the ground can be cleaned twice, avoiding the problem of missing a single roller brush 100 and improving the cleaning effect.

[0228] For example, Fig.15 As shown, the fixed ends 11 of the two roller brushes 100 are respectively located on different sides of the housing 200. The free ends 12 of the two roller brushes 100 can be arranged opposite to each other or staggered, and the free ends 12 of the two roller brushes 100 can be arranged close to the middle of the housing 200, so that the dust suction port 211 can be arranged in the middle of the housing 200, which can simplify the structure of the housing 200. When the free ends 12 of the two roller brushes 100 are respectively located on both sides of the housing 200, a dust suction port 211 can be respectively arranged on both sides of the housing 200 to improve the hair removal effect of the roller brush 100.

[0229] For example, Fig.16 As shown, the fixed ends 11 of the two roller brushes 100 are relatively arranged in the middle of the housing 200, so that the free ends 12 of the plurality of roller brushes 100 are respectively located on opposite sides of the housing 200. In this case, a suction port 211 can be respectively arranged on both sides of the housing 200, so that each roller brush 100 has a good hair removal effect.

[0230] It should be noted that Fig.14 , Fig.15 and Fig.16 It is merely a schematic diagram showing the locations of the multiple roller brushes 100 and does not constitute a limitation on the protection scope of the embodiments of the present application.

[0231] By providing a plurality of roller brushes 100 , the cleaning ability of the roller brush assembly 1000 can be improved, and by providing different roller brushes 100 at different positions, the design flexibility of the roller brush assembly 1000 can be improved.

[0232] It should be noted that the structures of the two roller brushes 100 may be the same or different, and may be set according to specific circumstances. In the embodiment of the present application, the structure of the roller brush 100 on the same roller brush assembly 1000 is not further limited.

[0233] It should be noted that the number of roller brushes 100 provided on the roller brush assembly 1000 can also be 3, 4, 5 or more. In the embodiment of the present application, the number of roller brushes 100 provided on the roller brush assembly 1000 is not further limited. In addition, when the number of roller brushes 100 is multiple, the setting positions of the multiple roller brushes 100 can be set as needed. In the embodiment of the present application, the setting of the multiple roller brushes 100 is not further limited.

[0234] It should be noted that when there is only one roller brush 100, the length of the roller brush 100 in the axial direction of the roller brush 100 is greater than or equal to the length of the opening 221. When there are multiple roller brushes 100, in the axial direction of the roller brush 100, the total projection area of ​​the multiple roller brushes 100 on the plane where the opening 221 is located covers the opening 221. In this way, all the positions passed by the roller brush assembly 1000 can be cleaned, the cleaning area can be increased, and missed sweeping can be prevented, thereby improving the cleaning efficiency.
