Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and more specifically, to a cleaning component and a vacuum cleaner. Background Art

[0002] Currently, in the vacuum cleaners in the related art, the roller brush is the component that first comes into contact with dust during vacuuming. During vacuuming, human hair, fabrics, fluffs, etc. are easily wound around the roller brush, resulting in a decline in the cleaning effect of the roller brush. At the same time, if not maintained, it will cause the bearing to become stuck and unable to work. Summary of the Invention

[0003] An embodiment of the present invention aims to at least solve one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of an embodiment of the present invention provides a cleaning component.

[0005] A second aspect of an embodiment of the present invention provides a vacuum cleaner.

[0006] In view of this, according to the first aspect of the embodiment of the present invention, a cleaning component is provided. The cleaning component includes: a housing provided with a receiving cavity; a first roller brush rotatably disposed in the housing and located in the receiving cavity, with a part of the first roller brush exposed outside the receiving cavity; a second roller brush rotatably disposed in the housing and located in the receiving cavity, and along the radial direction of the first roller brush, the second roller brush is located on at least one side of the first roller brush, with a part of the second roller brush exposed outside the receiving cavity; wherein, the second roller brush includes a winding part that can pick up objects to be cleaned.

[0007] The cleaning component provided by the embodiment of the present invention includes a housing, a first roller brush, and a second roller brush. Specifically, the housing is provided with a receiving cavity, both the first roller brush and the second roller brush are located in the receiving cavity, and both the first roller brush and the second roller brush can rotate relative to the housing.

[0008] A part of the first roller brush and a part of the second roller brush are both exposed outside the receiving cavity. It can be understood that the housing is also provided with an opening communicating with the receiving cavity, and a part of the first roller brush and a part of the second roller brush are both exposed outside the receiving cavity through the opening.

[0009] Specifically, when the cleaning component is in a working state, for example, when the user holds the cleaning component by hand or pushes a vertical push rod to drive the cleaning component to move on the surface to be cleaned, since the first roller brush and the second roller brush rotate relative to the housing, the objects to be cleaned on the surface to be cleaned can be cleaned.

[0010] It can be understood that the surface to be cleaned includes the ground, the bed surface, or the sofa surface, etc. The objects to be cleaned include dust, human hair, fabrics, fluffs, etc. that need to be cleaned.

[0011] In practical applications, when the first roller brush rotates relative to the housing to clean the object to be cleaned on the surface to be cleaned, human hair, fabrics, fluffs, etc. are easily wound around the first roller brush. After long-term use, the cleaning effect of the first roller brush decreases, and regular maintenance is required, which affects the user experience.

[0012] Along the radial direction of the first roller brush, the second roller brush is located on at least one side of the first roller brush. Specifically, along the radial direction of the first roller brush, the first roller brush includes an opposite first side and a second side. The second roller brush is located on the first side, or the second roller brush is located on the second side, or the number of the second roller brushes is two, and the two second roller brushes are respectively located on the first side and the second side. Specifically, it can be set according to actual needs.

[0013] It can be understood that the first side is the front end of the first roller brush, and the second side is the rear end of the first roller brush. When the user uses the vacuum cleaner with this cleaning component to do cleaning work, the general operation habit is to first push the cleaning component forward and then pull the cleaning component backward. Therefore, the second roller brush can be set on at least one side of the front and rear sides of the first roller brush.

[0014] The second roller brush includes a winding part, and the winding part can pick up the object to be cleaned. Therefore, the second roller brush can be used to pick up hairs, fabrics, fluffs and other objects to be cleaned on the surface to be cleaned, that is, the second roller brush arranged on at least one side of the first roller brush is used to actively pick up the object to be cleaned, so that most of the hairs, fabrics, fluffs, etc. on the surface to be cleaned are wound around the second roller brush. While ensuring the good cleaning effect of the cleaning component, the winding of hairs and the like on the first roller brush can be greatly reduced, and then the user can be exempted from the maintenance of the first roller brush, improving the user experience of the vacuum cleaner with this cleaning component.

[0015] Moreover, since the second roller brush is responsible for actively winding hairs and other objects to be cleaned, the hairs, fabrics, fluffs, etc. entering the dust cup in the vacuum cleaner body are less, so that the hairs wound around the separator of the vacuum cleaner are greatly reduced, and then the maintenance cycle of the separator can be extended, making the separator have a better maintenance-free experience, and at the same time eliminating the work of cleaning hairs on the separator, which is beneficial to further improving the user experience.

[0016] Optionally, the cleaning component further includes a driving member, and the driving member is connected to the first roller brush, so that under the drive of the driving member, the first roller brush can rotate relative to the housing in the accommodation cavity.

[0017] Optionally, the second roller brush is connected to the first roller brush. Specifically, a transmission wheel is provided on the second roller brush. That is to say, the second roller brush is connected to the first roller brush through the transmission wheel. Thus, during the rotation of the first roller brush relative to the housing, the second roller brush can be driven to rotate relative to the housing to clean the surface to be cleaned.

[0018] Since the second roller brush rotates driven by the first roller brush, that is to say, the second roller brush is not provided with a separate motor for driving, which is beneficial to reducing the production cost of the cleaning component and also conducive to saving the space of the cleaning component and realizing the miniaturization of the cleaning component.

[0019] Optionally, the power for the second roller brush to rotate relative to the housing comes from external wind or air flow. That is to say, the second roller brush is not provided with a separate motor for driving, which is beneficial to reducing the production cost of the cleaning component and also conducive to saving the space of the cleaning component and realizing the miniaturization of the cleaning component.

[0020] Optionally, the second roller brush is detachably connected to the housing. Since the second roller brush is used for winding hairs and other objects to be cleaned, after long-term use, that is, when the hairs and other objects to be cleaned wound on the second roller brush reach a certain degree, the second roller brush can be detached for cleaning or directly discarded and replaced with a new one, so that the cleaning component has the characteristics of no hair entanglement and maintenance-free.

[0021] Optionally, the second roller brush includes hard cardboard or plastic parts. It can be understood that the hard cardboard or plastic parts have low costs, which can greatly reduce the entanglement of hairs, fabrics, fluffs, etc. on the first roller brush and are beneficial to reducing the production cost of the cleaning component.

[0022] In addition, the cleaning component provided by the above technical solution of the present invention further has the following additional technical features:

[0023] In some technical solutions, optionally, the second roller brush includes a first brush body and a plurality of first brush hairs. Among them, the plurality of first brush hairs are spaced apart on the outer wall of the first brush body, at least a part of at least one first brush hair is exposed outside the accommodation cavity, and at least one first brush hair is provided with a winding part.

[0024] In this technical solution, it is defined that the second roller brush includes a first brush body and a plurality of first brush hairs. Specifically, the plurality of first brush hairs are spaced apart on the outer wall of the first brush body. That is to say, at least a part of each first brush hair protrudes from the outer wall of the first brush body. That is, the second roller brush is a hair-planting roller body.

[0025] At least one first brush hair is provided with a winding part. Since the winding part can pick up the objects to be cleaned, when the second roller brush rotates relative to the housing, it is easy to catch hairs, fabrics, fluffs, etc. on the surface to be cleaned, realizing the active winding function of the second roller brush.

[0026] So that most of the hairs and the like on the surface to be cleaned are sufficiently wound around the second roller brush, which can ensure a good cleaning effect of the cleaning component while significantly reducing the winding of hairs and the like on the first roller brush. Furthermore, the user can be spared the maintenance of the first roller brush, improving the user experience of the vacuum cleaner with this cleaning component.

[0027] Moreover, since the second roller brush is responsible for actively winding hairs and other objects to be cleaned, there are fewer hairs, fabrics, and fluffs entering the dust cup inside the vacuum cleaner body. As a result, the hairs and the like wound around the separator of the vacuum cleaner are significantly reduced, which can further extend the maintenance cycle of the separator, providing a better maintenance-free experience for the separator. At the same time, the work of cleaning hairs from the separator is eliminated, which is conducive to further enhancing the user experience.

[0028] Optionally, the winding part includes a concavo-convex structure, that is, a concavo-convex structure is provided on at least one first brush to easily catch hairs, fabrics, fluffs, and the like on the surface to be cleaned.

[0029] Optionally, the winding part includes an adhesive, that is, an adhesive is coated or provided on at least one first brush to easily adhere to hairs, fabrics, fluffs, and the like on the surface to be cleaned.

[0030] In some technical solutions, optionally, the part of at least one first brush exposed outside the accommodation cavity is an interference part, and the winding part is provided on the interference part.

[0031] In this technical solution, it is defined that the part of at least one first brush exposed outside the accommodation cavity is an interference part. It can be understood that when the cleaning component is in the working state, that is, when the user holds the cleaning component by hand or pushes the vertical push rod to drive the cleaning component to move on the surface to be cleaned, since the interference part is exposed outside the accommodation cavity, the interference part can be bent relative to the first brush to contact the surface to be cleaned.

[0032] Since the winding part is provided on the interference part, when the cleaning component is in the working state, the winding part can be in full contact with the objects to be cleaned on the surface to be cleaned, so as to further catch hairs, fabrics, fluffs, and the like on the surface to be cleaned, realizing the active winding function of the second roller brush, making the hairs and other objects to be cleaned fully wound around the second roller brush, thus significantly reducing the winding of hairs and the like on the first roller brush, and further enabling the user to be spared the maintenance of the first roller brush.

[0033] Optionally, each interference part of the first brush exposed outside the accommodation cavity is provided with a winding part.

[0034] In some technical solutions, optionally, the length of at least one interference part is greater than or equal to 1 mm.

[0035] In this technical solution, the value range of the length of at least one interference part is defined. That is to say, the length of contact between the first brush and the surface to be cleaned is defined, that is, the interference amount between the first brush and the surface to be cleaned is more than 1 mm.

[0036] Since the winding part is arranged on the interference part, when the cleaning assembly is in the working state, the winding part can be in full contact with the objects to be cleaned on the surface to be cleaned, so as to further catch hairs, fabrics, fluffs, etc. on the surface to be cleaned, realize the active winding function of the second roller brush, make the hairs and other objects to be cleaned fully wind around the second roller brush, thus greatly reducing the winding of hairs and the like on the first roller brush, and further enabling the user to be free from the maintenance of the first roller brush.

[0037] In some technical solutions, optionally, the winding part includes a concave-convex structure.

[0038] In this technical solution, it is defined that the winding part includes a concave-convex structure. That is to say, at least one first brush is provided with a concave-convex structure, that is, the surface of at least one first brush is uneven. Thus, when the second roller brush rotates relative to the housing, the concave-convex structure is easy to catch hairs, fabrics, fluffs, etc. on the surface to be cleaned, realize the active winding function of the second roller brush, make the hairs and other objects to be cleaned fully wind around the second roller brush, thus greatly reducing the winding of hairs and the like on the first roller brush, and further enabling the user to be free from the maintenance of the first roller brush.

[0039] Optionally, the concave-convex structure includes a plurality of grooves and / or a plurality of protrusions.

[0040] In some technical solutions, optionally, the concave-convex structure includes a plurality of grooves. The plurality of grooves are spaced apart, and the distance between the notch of at least one groove and the outer wall of the first brush body is less than the distance between the bottom of the groove and the outer wall of the first brush body.

[0041] In this technical solution, the specific structure of the concave-convex structure is defined. Specifically, the concave-convex structure includes a plurality of grooves, and the plurality of grooves are spaced apart. So as to form a concave-convex structure on the surface of at least one first brush.

[0042] The distance between the notch of at least one groove and the outer wall of the first brush body is less than the distance between the bottom of the groove and the outer wall of the first brush body. That is to say, the notch of at least one groove faces the first brush body, forming a barb structure.

[0043] That is, at least one first brush has a barbed structure. Specifically, the second roller brush is similar to an electrostatic brush. Thus, when the second roller brush rotates relative to the housing, it can easily catch hairs, fabrics, fluffs, etc. on the surface to be cleaned, realizing the active winding function of the second roller brush, enabling the hairs and other objects to be cleaned to fully wind around the second roller brush, thereby significantly reducing the winding of hairs, etc. on the first roller brush, and further enabling the user to be free from the maintenance of the first roller brush.

[0044] In some technical solutions, optionally, the width of the bottom of at least one groove is smaller than the width of the opening of the groove.

[0045] In this technical solution, it is defined that the width of the bottom of at least one groove is smaller than the width of the opening of the groove. Thus, when hairs, fabrics, fluffs, etc. to be cleaned are wound in the grooves of the first brush, they are not easily detached from the grooves, further improving the effect of the second roller brush actively winding the objects to be cleaned.

[0046] In some technical solutions, optionally, the first roller brush includes a second brush body and a plurality of second brushes. Among them, the plurality of second brushes are spaced on the second brush body, and at least a part of each second brush protrudes from the outer wall of the second brush body; the hardness of at least one first brush is less than the hardness of each second brush.

[0047] In this technical solution, it is defined that the first roller brush includes a second brush body and a plurality of second brushes. Specifically, the plurality of second brushes are spaced on the second brush body, and at least a part of each second brush protrudes from the outer wall of the second brush body. That is to say, the first roller brush is a tufted roller body. When the first roller brush rotates relative to the housing and contacts the surface to be cleaned through the part exposed outside the accommodation cavity, it can improve the dust removal effect of the cleaning assembly on the surface to be cleaned.

[0048] The hardness of at least one first brush is less than the hardness of each second brush. That is to say, the hardness of the first brush on the second roller brush is set to be smaller, that is, the first brush on the second roller brush is relatively soft. Thus, when the second roller brush rotates relative to the housing, it can easily catch hairs, fabrics, fluffs, etc. on the surface to be cleaned, realizing the active winding function of the second roller brush, enabling the hairs and other objects to be cleaned to fully wind around the second roller brush, thereby significantly reducing the winding of hairs, etc. on the first roller brush, and further enabling the user to be free from the maintenance of the first roller brush.

[0049] At the same time, since the hardness of the second brush on the first roller brush is relatively large, it can further reduce the winding of hairs, fabrics, fluffs, etc. on the first roller brush.

[0050] In some technical solutions, optionally, the first rotatable brush further includes at least one anti-tangling part, and the at least one anti-tangling part is disposed on the outer wall of the second brush body and is located on at least one side of at least one second brush along the circumferential direction of the first rotatable brush, and the at least one anti-tangling part is disposed close to the at least one second brush.

[0051] In this technical solution, it is defined that the first rotatable brush further includes at least one anti-tangling part. Specifically, the at least one anti-tangling part is disposed on the outer wall of the second brush body, and along the circumferential direction of the first rotatable brush, the at least one anti-tangling part is located on at least one side of at least one second brush.

[0052] Specifically, along the circumferential direction of the first rotatable brush, at least one second brush includes a first side and a second side. The at least one anti-tangling part is located on the first side of at least one second brush and is disposed close to the second brush. Alternatively, the at least one anti-tangling part is located on the second side of at least one second brush and is disposed close to the second brush. Alternatively, the at least one anti-tangling part is located on the first side of at least one second brush and is disposed close to the second brush, and at the same time, the at least one anti-tangling part is located on the second side of at least one second brush and is disposed close to the second brush. It can be specifically set according to actual needs.

[0053] By disposing the anti-tangling part on at least one side in the circumferential direction of at least one second brush, the winding effect of hair, fabric, flocs, etc. on the first rotatable brush can be further reduced, so that the user can be exempt from maintaining the first rotatable brush, and the user experience is improved.

[0054] Optionally, the anti-tangling part includes an adhesive strip or a baffle.

[0055] In some technical solutions, optionally, along the radial direction of the first rotatable brush, the height of at least one anti-tangling part is greater than the protruding height of at least one second brush on the outer wall of the second brush body.

[0056] In this technical solution, along the radial direction of the first rotatable brush, at least one anti-tangling part is higher than at least one second brush, so that the winding situation of hair, etc. on the first rotatable brush can be effectively improved, so that the user can be exempt from maintaining the first rotatable brush, and the user experience is improved.

[0057] Optionally, along the radial direction of the first rotatable brush, the height of at least one anti-tangling part is greater than the protruding height of each second brush on the outer wall of the second brush body to further improve the anti-winding effect of the first rotatable brush.

[0058] In some technical solutions, optionally, between the height h1 of at least one anti-tangling part and the protruding height h2 of at least one second brush on the outer wall of the second brush body along the radial direction of the first rotatable brush, 0.6h1 ≤ h2 ≤ 0.9h1 is satisfied.

[0059] In this technical solution, the ratio range between the height of at least one anti-tangling part and the protruding height of at least one second brush on the outer wall of the second brush body is defined along the radial direction of the first roller brush. That is to say, the protruding height of at least one second brush on the outer wall of the second brush body is 60% to 90% of the height of at least one anti-tangling part.

[0060] It can be understood that when the cleaning assembly is in the working state, the first roller brush plays a major cleaning role. By defining the ratio range between the height of the anti-tangling part and the height of the second brush, it is possible to reduce the winding effect of hair, fabric, flocs, etc. on the first roller brush while ensuring the effective cleaning effect of the cleaning assembly, so that the user can be exempted from the maintenance of the first roller brush and improve the user experience.

[0061] In some technical solutions, optionally, the housing is further provided with an opening, the opening communicates with the accommodating cavity, and a part of the first roller brush and a part of the second roller brush are respectively exposed outside the accommodating cavity through the opening; the cleaning assembly further includes at least one shielding part, at least one shielding part is arranged on the housing and is located at the opening, and along the radial direction of the first roller brush, at least one shielding part is opposite to at least one end of the first roller brush in the axial direction.

[0062] In this technical solution, it is defined that the cleaning assembly further includes at least one shielding part. Specifically, the housing is further provided with an opening, the opening communicates with the accommodating cavity, and a part of the first roller brush and a part of the second roller brush are both exposed outside the accommodating cavity through the opening.

[0063] At least one shielding part is arranged on the housing, and at least one shielding part is located at the opening. Along the axial direction of the first roller brush, the first roller brush includes at least one end. Specifically, the first roller brush includes a first end and a second end that face away from each other. It can be understood that the first end of the first roller brush is used to connect the driving part, and the second end of the first roller brush is rotatably connected to the housing, so that the first roller brush can rotate relative to the housing under the drive of the driving part.

[0064] Along the radial direction of the first roller brush, at least one shielding part is opposite to at least one end of the first roller brush. Specifically, along the radial direction of the first roller brush, the shielding part is opposite to the first end of the first roller brush, or along the radial direction of the first roller brush, the shielding part is opposite to the second end of the first roller brush. Or, the number of shielding parts is two, and along the radial direction of the first roller brush, the two shielding parts are respectively opposite to the first end of the first roller brush and the second end of the first roller brush.

[0065] By providing shielding parts at positions radially opposite to the ends of the first rotating brush, it is possible to prevent cleaning objects such as hair, fabric, and fluffs from entering both ends of the first rotating brush without affecting other main performance of the cleaning assembly, such as dust removal and noise reduction. Thus, it effectively solves the problem that the bearings are jammed due to hair winding at both ends of the first rotating brush, which further leads to the inability to work, ensuring the normal dust removal operation of the vacuum cleaner with this cleaning assembly and improving the dust removal efficiency of the vacuum cleaner.

[0066] Optionally, the shielding part and the housing are of an integral structure.

[0067] In some technical solutions, optionally, the second rotating brush is connected to the first rotating brush, and the first rotating brush can drive the second rotating brush to rotate; or the second rotating brush is used to rotate under the action of external air flow or wind force.

[0068] In this technical solution, specifically, the second rotating brush is connected to the first rotating brush. When the first rotating brush rotates relative to the housing, it can drive the second rotating brush to rotate relative to the housing.

[0069] Optionally, the second rotating brush is provided with a transmission wheel. That is to say, the second rotating brush is connected to the first rotating brush through the transmission wheel. Thus, during the rotation of the first rotating brush relative to the housing, it can drive the second rotating brush to rotate relative to the housing to clean the surface to be cleaned.

[0070] Since the second rotating brush is driven by the first rotating brush, that is to say, the second rotating brush is not provided with a separate motor for driving. Thus, it can significantly reduce the winding of hair and the like on the first rotating brush. Furthermore, while the user can be exempted from maintaining the first rotating brush, it is beneficial to reduce the production cost of the cleaning assembly, and it is also beneficial to save the space of the cleaning assembly and realize the miniaturization of the cleaning assembly.

[0071] Or, the second rotating brush is used to rotate under the action of external air flow or wind force. That is to say, the power for the second rotating brush to rotate relative to the housing comes from external wind force or air flow, that is, the second rotating brush is not provided with a separate motor for driving. Thus, it can significantly reduce the winding of hair and the like on the first rotating brush. Furthermore, while the user can be exempted from maintaining the first rotating brush, it is beneficial to reduce the production cost of the cleaning assembly, and it is also beneficial to save the space of the cleaning assembly and realize the miniaturization of the cleaning assembly.

[0072] In some technical solutions, optionally, the second rotating brush is detachably connected to the housing.

[0073] In this technical solution, it is defined that the second rotating brush is detachably connected to the housing. Since the second rotating brush is used to wind cleaning objects such as hair, after long-term use, that is, when the hair and other cleaning objects on the second rotating brush are wound to a certain extent, the second rotating brush can be detached for cleaning or directly discarded and replaced with a new one. Thus, the cleaning assembly has the characteristics of no hair winding and maintenance-free.

[0074] In some technical solutions, optionally, the number of the second rotatable brushes is multiple, and each second rotatable brush is a disposable component.

[0075] In this technical solution, it is defined that the number of the second rotatable brushes is multiple. Specifically, each second rotatable brush is a disposable component.

[0076] Since the second rotatable brush is used for winding hairs and other cleaning objects, after long-term use, that is, when the hairs and other cleaning objects wound on the second rotatable brush reach a certain degree, the second rotatable brush can be disassembled and directly replaced with a new one, that is, the second rotatable brush is a disposable component. Thus, while effectively cleaning the surface to be cleaned, the cleaning assembly has the characteristics of no hair entanglement and maintenance-free, further improving the user experience of the vacuum cleaner with this cleaning assembly.

[0077] According to the second aspect of the present invention, there is provided a vacuum cleaner including the cleaning assembly provided in any of the above technical solutions, and thus has all the beneficial technical effects of this cleaning assembly, which will not be elaborated herein.

[0078] Optionally, the vacuum cleaner includes a fan assembly and a connecting pipe assembly. Two ends of the connecting pipe assembly are respectively communicated with the fan assembly and the accommodating cavity. When the fan assembly is in a working state, it can generate a suction airflow, so as to provide suction when the user operates the cleaning assembly to clean the surface to be cleaned, and achieve the dust suction effect of the vacuum cleaner.

[0079] Optionally, the vacuum cleaner includes a handheld rechargeable vacuum cleaner or a floor sweeping robot.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0097] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those described herein. Therefore, the scope of the present invention is not limited by the specific embodiments disclosed below.

[0098] Reference will now be made to Figures 1 to 12 describe a cleaning assembly 100 and a vacuum cleaner provided according to some embodiments of the present invention.

[0099] In one embodiment according to the present application, as Figure 1 , Figure 2 , Figure 11 and Figure 12 shown, a cleaning assembly 100 is provided. The cleaning assembly 100 includes: a housing 110 having a receiving cavity 111; a first roller brush 120 rotatably disposed in the housing 110 and located in the receiving cavity 111, with a part of the first roller brush 120 exposed outside the receiving cavity 111; a second roller brush 130 rotatably disposed in the housing 110 and located in the receiving cavity 111, the second roller brush 130 being located on at least one side of the first roller brush 120 in the radial direction of the first roller brush 120, and a part of the second roller brush 130 being exposed outside the receiving cavity 111; wherein, the second roller brush 130 includes a winding portion 133 that can pick up objects to be cleaned.

[0100] The cleaning assembly 100 provided by the embodiments of the present invention includes a housing 110, a first roller brush 120, and a second roller brush 130. Specifically, the housing 110 is provided with a receiving cavity 111, the first roller brush 120 and the second roller brush 130 are both located in the receiving cavity 111, and both the first roller brush 120 and the second roller brush 130 can rotate relative to the housing 110.

[0101] A part of the first roller brush 120 and a part of the second roller brush 130 are both exposed outside the receiving cavity 111. It can be understood that the housing 110 is further provided with an opening 112 communicating with the receiving cavity 111, and a part of the first roller brush 120 and a part of the second roller brush 130 are both exposed outside the receiving cavity 111 through the opening 112.

[0102] Specifically, when the cleaning assembly 100 is in a working state, for example, when the user holds the cleaning assembly 100 by hand or drives the cleaning assembly 100 to move on the surface to be cleaned by pushing a vertical push rod, since the first roller brush 120 and the second roller brush 130 rotate relative to the housing 110, the objects to be cleaned on the surface to be cleaned can be cleaned.

[0103] It can be understood that the surface to be cleaned includes a floor, a bed surface, a sofa surface, etc. The objects to be cleaned include dust, human hair, fabrics, fluffs, and other objects that need to be cleaned.

[0104] In practical applications, when the first roller brush 120 rotates relative to the housing 110 to clean the objects to be cleaned on the surface to be cleaned, human hair, fabrics, fluffs, etc. are easily wound around the first roller brush 120. After long-term use, the cleaning effect of the first roller brush 120 decreases, and regular maintenance is required, which affects the user experience.

[0105] Along the radial direction of the first roller brush 120, the second roller brush 130 is located on at least one side of the first roller brush 120. Specifically, along the radial direction of the first roller brush 120, the first roller brush 120 includes an opposite first side and a second side. The second roller brush 130 is located on the first side, or the second roller brush 130 is located on the second side, or the number of the second roller brushes 130 is two, and the two second roller brushes 130 are respectively located on the first side and the second side. Specifically, it can be set according to actual needs.

[0106] It can be understood that the first side is the front end of the first roller brush 120, and the second side is the rear end of the first roller brush 120. When the user uses the vacuum cleaner with the cleaning assembly 100 for cleaning work, the general operation habit is to first push the cleaning assembly 100 forward and then pull the cleaning assembly 100 backward. Therefore, the second roller brush 130 can be arranged on at least one side of the front and rear sides of the first roller brush 120.

[0107] The second roller brush 130 includes a winding part 133, and the winding part 133 can pick up the objects to be cleaned. Therefore, the second roller brush 130 can be used to pick up the hair, fabrics, fluffs and other objects to be cleaned on the surface to be cleaned, that is, the second roller brush 130 arranged on at least one side of the first roller brush 120 is used to actively pick up the objects to be cleaned, so that most of the hair, fabrics, fluffs, etc. on the surface to be cleaned are wound around the second roller brush 130, which can ensure the good cleaning effect of the cleaning assembly 100 while greatly reducing the winding of hair and the like on the first roller brush 120. Furthermore, the user can be exempted from the maintenance of the first roller brush 120, improving the user experience of the vacuum cleaner with the cleaning assembly 100.

[0108] Moreover, since the second roller brush 130 is responsible for actively winding the hair and other objects to be cleaned, the hair, fabrics, fluffs, etc. entering the dust cup inside the vacuum cleaner body are less, so that the hair and the like wound around the separator of the vacuum cleaner are greatly reduced. Furthermore, the maintenance cycle of the separator can be extended, making the separator have a better maintenance-free experience, and at the same time exempting the work of cleaning the hair on the separator, which is beneficial to further improving the user experience.

[0109] Optionally, the cleaning assembly 100 further includes a driving member, and the driving member is connected to the first roller brush 120, so that the first roller brush 120 can rotate relative to the housing 110 in the accommodation cavity 111 under the drive of the driving member.

[0110] Optionally, the second roller brush 130 is connected to the first roller brush 120. Specifically, the second roller brush 130 is provided with a transmission wheel. That is to say, the second roller brush 130 is connected to the first roller brush 120 through the transmission wheel. Thus, during the rotation of the first roller brush 120 relative to the housing 110, the second roller brush 130 can be driven to rotate relative to the housing 110 to clean the surface to be cleaned.

[0111] Since the second roller brush 130 is driven to rotate by the first roller brush 120, that is to say, the second roller brush 130 is not provided with a separate motor for driving, which is beneficial to reducing the production cost of the cleaning assembly 100 and also beneficial to saving the space of the cleaning assembly 100, realizing the miniaturization of the cleaning assembly 100.

[0112] Optionally, the power for the second roller brush 130 to rotate relative to the housing 110 comes from external wind force or air flow. That is to say, the second roller brush 130 is not provided with a separate motor for driving, which is beneficial to reducing the production cost of the cleaning assembly 100 and also beneficial to saving the space of the cleaning assembly 100, realizing the miniaturization of the cleaning assembly 100.

[0113] Optionally, the second roller brush 130 is detachably connected to the housing 110. Since the second roller brush 130 is used to wind hairs and other objects to be cleaned, after long-term use, that is, when the hairs and other objects to be cleaned on the second roller brush 130 are wound to a certain extent, the second roller brush 130 can be detached for cleaning or directly discarded and replaced with a new one, so that the cleaning assembly 100 has the characteristics of no hair winding and maintenance-free.

[0114] Optionally, the second roller brush 130 includes hard cardboard or plastic parts. It can be understood that the hard cardboard or plastic parts have low costs, so that while greatly reducing the winding of hairs, fabrics, fluffs, etc. on the first roller brush 120, it is beneficial to reduce the production cost of the cleaning assembly 100.

[0115] Such as Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown in

[0116] In this embodiment, it is defined that the second roller brush 130 includes a first brush body 131 and a plurality of first hair brushes 132. Specifically, the plurality of first hair brushes 132 are arranged at intervals on the outer wall of the first brush body 131. That is to say, at least a part of each first hair brush 132 protrudes from the outer wall of the first brush body 131. Namely, the second roller brush 130 is a hair-implanted roller body.

[0117] At least one first hair brush 132 is provided with a winding part 133. Since the winding part 133 can pick up the object to be cleaned, when the second roller brush 130 rotates relative to the housing 110, it is easy to hang the hair, fabric, flocs, etc. on the surface to be cleaned, realizing the active winding function of the second roller brush 130.

[0118] That is, most of the hair and the like on the surface to be cleaned are fully wound around the second roller brush 130. While ensuring the good cleaning effect of the cleaning assembly 100, the winding of hair and the like on the first roller brush 120 can be greatly reduced. Furthermore, the user can be exempted from the maintenance of the first roller brush 120, improving the user experience of the vacuum cleaner with the cleaning assembly 100.

[0119] Moreover, since the second roller brush 130 is responsible for actively winding the hair and other objects to be cleaned, less hair, fabric, flocs, etc. enter the dust cup inside the vacuum cleaner body. As a result, the hair and the like wound around the separator of the vacuum cleaner are greatly reduced. Furthermore, the maintenance cycle of the separator can be extended, making the separator have a better maintenance-free experience. At the same time, the work of cleaning the hair on the separator is eliminated, which is beneficial to further improving the user experience.

[0120] Optionally, the winding part 133 includes a concave-convex structure 134, that is, a concave-convex structure 134 is provided on at least one first hair brush 132 to easily hang the hair, fabric, flocs, etc. on the surface to be cleaned.

[0121] Optionally, the winding part 133 includes an adhesive. That is, an adhesive is coated or provided on at least one first hair brush 132 to easily adhere to the hair, fabric, flocs, etc. on the surface to be cleaned.

[0122] Such as Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, in some embodiments, optionally, the part of at least one first hair brush 132 exposed outside the accommodation cavity 111 is an interference part 136, and the interference part 136 is provided with a winding part 133.

[0123] In this embodiment, the portion of at least one first brush 132 exposed outside the accommodation cavity 111 is defined as an interference portion 136. It can be understood that when the cleaning assembly 100 is in a working state, that is, when the user holds the cleaning assembly 100 by hand or drives the cleaning assembly 100 to move on the surface to be cleaned by pushing a vertical push rod, since the interference portion 136 is exposed outside the accommodation cavity 111, the interference portion 136 can be bent relative to the first brush 132 to contact the surface to be cleaned.

[0124] Since the winding portion 133 is provided on the interference portion 136, when the cleaning assembly 100 is in a working state, the winding portion 133 can be in full contact with the objects to be cleaned on the surface to be cleaned, so as to further catch hairs, fabrics, fluffs, etc. on the surface to be cleaned, realize the active winding function of the second roller brush 130, make the hairs and other objects to be cleaned fully wound around the second roller brush 130, thereby greatly reducing the winding of hairs and the like on the first roller brush 120, and further enabling the user to be exempt from the maintenance of the first roller brush 120.

[0125] Optionally, a winding portion 133 is provided on each interference portion 136 of the first brush 132 exposed outside the accommodation cavity 111.

[0126] In some embodiments, optionally, the length of at least one interference portion 136 is greater than or equal to 1 mm.

[0127] In this embodiment, the value range of the length of at least one interference portion 136 is defined, that is, the length of contact between the first brush 132 and the surface to be cleaned is defined, that is, the interference amount between the first brush 132 and the surface to be cleaned is more than 1 mm.

[0128] Since the winding portion 133 is provided on the interference portion 136, when the cleaning assembly 100 is in a working state, the winding portion 133 can be in full contact with the objects to be cleaned on the surface to be cleaned, so as to further catch hairs, fabrics, fluffs, etc. on the surface to be cleaned, realize the active winding function of the second roller brush 130, make the hairs and other objects to be cleaned fully wound around the second roller brush 130, thereby greatly reducing the winding of hairs and the like on the first roller brush 120, and further enabling the user to be exempt from the maintenance of the first roller brush 120.

[0129] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 shown, in some embodiments, optionally, the winding portion 133 includes a concavo-convex structure 134.

[0130] In this embodiment, it is defined that the winding part 133 includes a concavo-convex structure 134, that is to say, at least one first brush 132 is provided with a concavo-convex structure 134, that is, the surface of at least one first brush 132 is uneven, so that when the second roller brush 130 rotates relative to the housing 110, the concavo-convex structure can easily catch hairs, fabrics, fluffs, etc. on the surface to be cleaned, realizing the active winding function of the second roller brush 130, making the hairs and other objects to be cleaned fully wound around the second roller brush 130, thereby greatly reducing the winding of hairs and the like on the first roller brush 120, and further enabling the user to be exempt from maintaining the first roller brush 120.

[0131] Optionally, the concavo-convex structure 134 includes a plurality of grooves 135 and / or a plurality of protrusions.

[0132] As Figure 6 and Figure 7 shown, in some embodiments, optionally, the concavo-convex structure 134 includes a plurality of grooves 135, the plurality of grooves 135 are spaced apart, and the distance between the notch 137 of at least one groove 135 and the outer wall of the first brush body 131 is less than the distance between the bottom 138 of the groove 135 and the outer wall of the first brush body 131.

[0133] In this embodiment, the specific structure of the concavo-convex structure 134 is defined. Specifically, the concavo-convex structure 134 includes a plurality of grooves 135, and the plurality of grooves 135 are spaced apart, so as to form a concavo-convex structure 134 on the surface of at least one first brush 132.

[0134] The distance between the notch 137 of at least one groove 135 and the outer wall of the first brush body 131 is less than the distance between the bottom 138 of the groove 135 and the outer wall of the first brush body 131. That is to say, the notch 137 of at least one groove 135 faces the first brush body 131, forming a barb structure.

[0135] That is, at least one first brush 132 has a barb structure. Specifically, the second roller brush 130 is similar to an electrostatic brush. Thus, when the second roller brush 130 rotates relative to the housing 110, it can easily catch hairs, fabrics, fluffs, etc. on the surface to be cleaned, realizing the active winding function of the second roller brush 130, making the hairs and other objects to be cleaned fully wound around the second roller brush 130, thereby greatly reducing the winding of hairs and the like on the first roller brush 120, and further enabling the user to be exempt from maintaining the first roller brush 120.

[0136] As Figure 7 shown, in some embodiments, optionally, the width of the bottom 138 of at least one groove 135 is less than the width of the notch 137 of the groove 135.

[0137] In this embodiment, the width of the groove bottom 138 of at least one groove 135 is defined to be smaller than the width of the notch 137 of the groove 135. Therefore, when hair, fabrics and flocculent objects to be cleaned are entangled in the groove 135 of the first brush 132, they are not easy to fall out of the groove 135, further improving the effect of the second roller brush 130 actively entangled with the objects to be cleaned.

[0138] like Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, optionally, the first roller brush 120 includes a second brush body 121 and a plurality of second brushes 122, wherein the plurality of second brushes 122 are spaced apart in the second brush body 121, and at least a portion of each second brush 122 protrudes from an outer wall of the second brush body 121; and the hardness of at least one first brush 132 is less than the hardness of each second brush 122.

[0139] In this embodiment, it is defined that the first roller brush 120 includes a second brush body 121 and a plurality of second brushes 122. Specifically, the plurality of second brushes 122 are arranged on the second brush body 121 at intervals, and at least a portion of each second brush 122 protrudes from the outer wall of the second brush body 121, that is, the first roller brush 120 is a hair-planted roller. When the first roller brush 120 rotates relative to the housing 110 and contacts the surface to be cleaned through the portion exposed in the accommodating cavity 111, the dust removal effect of the cleaning assembly 100 on the surface to be cleaned can be improved.

[0140] The hardness of at least one first brush 132 is less than the hardness of each second brush 122, that is, the hardness of the first brush 132 on the second roller brush 130 is set to be smaller, that is, the first brush 132 on the second roller brush 130 is relatively soft, so that when the second roller brush 130 rotates relative to the shell 110, it is easy to catch the hair, fabric, flocculent material, etc. on the surface to be cleaned, thereby realizing the active winding function of the second roller brush 130, so that the hair waiting to be cleaned is fully wound around the second roller brush 130, thereby greatly reducing the winding of hair, etc. on the first roller brush 120, and thus allowing the user to be exempted from the maintenance of the first roller brush 120.

[0141] At the same time, since the second brush 122 on the first roller brush 120 has a greater hardness, the entanglement of hair, fabric, flocs, etc. on the first roller brush 120 can be further reduced.

[0142] like Figure 8 , Figure 9 and Figure 10As shown, in some embodiments, optionally, the first roller brush 120 further includes at least one anti - entanglement part 123. The at least one anti - entanglement part 123 is provided on the outer wall of the second brush body 121 and is located on at least one side of at least one second hair brush 122 along the circumferential direction of the first roller brush 120. The at least one anti - entanglement part 123 is arranged close to the at least one second hair brush 122.

[0143] In this embodiment, it is defined that the first roller brush 120 further includes at least one anti - entanglement part 123. Specifically, the at least one anti - entanglement part 123 is arranged on the outer wall of the second brush body 121, and along the circumferential direction of the first roller brush 120, the at least one anti - entanglement part 123 is located on at least one side of at least one second hair brush 122.

[0144] Specifically, along the circumferential direction of the first roller brush 120, at least one second hair brush 122 includes a first side and a second side. The at least one anti - entanglement part 123 is located on the first side of at least one second hair brush 122 and is arranged close to the second hair brush 122. Or, the at least one anti - entanglement part 123 is located on the second side of at least one second hair brush 122 and is arranged close to the second hair brush 122. Or, the at least one anti - entanglement part 123 is located on the first side of at least one second hair brush 122 and is arranged close to the second hair brush 122, and at the same time, the at least one anti - entanglement part 123 is located on the second side of at least one second hair brush 122 and is arranged close to the second hair brush 122. It can be specifically set according to actual needs.

[0145] By arranging the anti - entanglement part 123 on at least one side in the circumferential direction of at least one second hair brush 122, the winding effect of hair, fabric, flocs, etc. on the first roller brush 120 can be further reduced, enabling the user to be free from the maintenance of the first roller brush 120 and improving the user experience.

[0146] Optionally, the anti - entanglement part 123 includes an adhesive strip or a baffle.

[0147] As Figure 9 shown, in some embodiments, optionally, along the radial direction of the first roller brush 120, the height of at least one anti - entanglement part 123 is greater than the protruding height of at least one second hair brush 122 on the outer wall of the second brush body 121.

[0148] In this embodiment, along the radial direction of the first roller brush 120, at least one anti - entanglement part 123 is higher than at least one second hair brush 122, thereby effectively improving the winding situation of hair, etc. on the first roller brush 120, enabling the user to be free from the maintenance of the first roller brush 120 and improving the user experience.

[0149] Optionally, along the radial direction of the first roller brush 120, the height of at least one anti - entanglement part 123 is greater than the protruding height of each second hair brush 122 on the outer wall of the second brush body 121 to further improve the anti - winding effect of the first roller brush 120.

[0150] As Figure 9 shown, in some embodiments, optionally, along the radial direction of the first roller brush 120, between the height h1 of at least one anti-tangling portion 123 and the protruding height h2 of at least one second brush 122 on the outer wall of the second brush body 121, it satisfies 0.6h1 ≤ h2 ≤ 0.9h1.

[0151] In this embodiment, the proportional range between the height of at least one anti-tangling portion 123 and the protruding height of at least one second brush 122 on the outer wall of the second brush body 121 is defined along the radial direction of the first roller brush 120. That is to say, the protruding height of at least one second brush 122 on the outer wall of the second brush body 121 is 60% - 90% of the height of at least one anti-tangling portion 123.

[0152] It can be understood that when the cleaning assembly 100 is in a working state, the first roller brush 120 plays a main cleaning role. By defining the proportional range between the height of the anti-tangling portion 123 and the height of the second brush 122, while ensuring the effective cleaning effect of the cleaning assembly 100, the winding effect of hair, fabric, flocs, etc. on the first roller brush 120 can be reduced, so that the user can be exempted from the maintenance of the first roller brush 120 and the user experience can be improved.

[0153] As Figure 1 and Figure 2 shown, in some embodiments, optionally, the housing 110 is further provided with an opening 112, the opening 112 communicates with the accommodation cavity 111, and a part of the first roller brush 120 and a part of the second roller brush 130 are respectively exposed outside the accommodation cavity 111 through the opening 112; the cleaning assembly 100 further includes at least one shielding portion 140, at least one shielding portion 140 is arranged on the housing 110 and is located at the opening 112, and along the radial direction of the first roller brush 120, at least one shielding portion 140 is opposite to at least one end portion of the first roller brush 120 in the axial direction.

[0154] In this embodiment, it is defined that the cleaning assembly 100 further includes at least one shielding portion 140. Specifically, the housing 110 is further provided with an opening 112, the opening 112 communicates with the accommodation cavity 111, and a part of the first roller brush 120 and a part of the second roller brush 130 are both exposed outside the accommodation cavity 111 through the opening 112.

[0155] At least one shielding part 140 is arranged on the housing 110, and at least one shielding part 140 is located at the opening 112. Along the axial direction of the first rolling brush 120, the first rolling brush 120 includes at least one end. Specifically, the first rolling brush 120 includes a first end and a second end that face away from each other. It can be understood that the first end of the first rolling brush 120 is used to connect to the driving part, and the second end of the first rolling brush 120 is rotatably connected to the housing 110, so that under the drive of the driving part, the first rolling brush 120 can rotate relative to the housing 110.

[0156] Along the radial direction of the first rolling brush 120, at least one shielding part 140 is opposite to at least one end of the first rolling brush 120. Specifically, along the radial direction of the first rolling brush 120, the shielding part 140 is opposite to the first end of the first rolling brush 120, or along the radial direction of the first rolling brush 120, the shielding part 140 is opposite to the second end of the first rolling brush 120. Or, the number of the shielding parts 140 is two, and along the radial direction of the first rolling brush 120, the two shielding parts 140 are respectively opposite to the first end of the first rolling brush 120 and the second end of the first rolling brush 120.

[0157] By arranging the shielding part 140 at a position radially opposite to the ends of the first rolling brush 120, it is possible to prevent cleaning objects such as hair, fabric, and flocs from entering both ends of the first rolling brush 120 without affecting other main performances of the cleaning assembly 100 such as dust removal and noise reduction, thereby effectively solving the situation where the bearing is jammed due to hair winding at both ends of the first rolling brush 120, and then unable to work, ensuring the normal dust removal work of the vacuum cleaner with the cleaning assembly 100, and improving the dust removal efficiency of the vacuum cleaner.

[0158] Optionally, the shielding part 140 and the housing 110 are of an integral structure.

[0159] In some embodiments, optionally, the second rolling brush 130 is connected to the first rolling brush 120, and the first rolling brush 120 can drive the second rolling brush 130 to rotate; or the second rolling brush 130 is used to rotate under the action of external air flow or wind force.

[0160] In this embodiment, specifically, the second rolling brush 130 is connected to the first rolling brush 120, and when the first rolling brush 120 rotates relative to the housing 110, it can drive the second rolling brush 130 to rotate relative to the housing 110.

[0161] Optionally, the second rolling brush 130 is provided with a transmission wheel, that is to say, the second rolling brush 130 is connected to the first rolling brush 120 through the transmission wheel, so that during the process of the first rolling brush 120 rotating relative to the housing 110, it can drive the second rolling brush 130 to rotate relative to the housing 110 to clean the surface to be cleaned.

[0162] Since the second rotatable brush 130 rotates driven by the first rotatable brush 120, that is to say, the second rotatable brush 130 is not provided with a separate motor for driving, so that the winding of hair and the like on the first rotatable brush 120 can be greatly reduced. Furthermore, while the user can be exempted from maintaining the first rotatable brush 120, it is beneficial to reduce the production cost of the cleaning assembly 100, and it is also beneficial to save the space of the cleaning assembly 100, realizing miniaturization of the cleaning assembly 100.

[0163] Alternatively, the second rotatable brush 130 is used to rotate under the action of external air flow or wind force, that is to say, the power for the second rotatable brush 130 to rotate relative to the housing 110 comes from external wind force or air flow, that is, the second rotatable brush 130 is not provided with a separate motor for driving, so that the winding of hair and the like on the first rotatable brush 120 can be greatly reduced. Furthermore, while the user can be exempted from maintaining the first rotatable brush 120, it is beneficial to reduce the production cost of the cleaning assembly 100, and it is also beneficial to save the space of the cleaning assembly 100, realizing miniaturization of the cleaning assembly 100.

[0164] In some embodiments, optionally, the second rotatable brush 130 is detachably connected to the housing 110.

[0165] In this embodiment, it is defined that the second rotatable brush 130 is detachably connected to the housing 110. Since the second rotatable brush 130 is used to wind hair and other objects to be cleaned, after long-term use, that is, after the hair and other objects to be cleaned on the second rotatable brush 130 are wound to a certain extent, the second rotatable brush 130 can be detached for cleaning or directly discarded and replaced with a new one, so that the cleaning assembly 100 has the characteristics of no hair winding and maintenance-free.

[0166] In some embodiments, optionally, the number of the second rotatable brushes 130 is multiple, and each second rotatable brush 130 is a disposable component.

[0167] In this embodiment, it is defined that the number of the second rotatable brushes 130 is multiple. Specifically, each second rotatable brush 130 is a disposable component.

[0168] Since the second rotatable brush 130 is used to wind hair and other objects to be cleaned, after long-term use, that is, after the hair and other objects to be cleaned on the second rotatable brush 130 are wound to a certain extent, the second rotatable brush 130 can be detached and directly discarded and replaced with a new one, that is, the second rotatable brush 130 is a disposable component, so that while effectively cleaning the surface to be cleaned, the cleaning assembly 100 has the characteristics of no hair winding and maintenance-free, further improving the user experience of the vacuum cleaner with the cleaning assembly 100.

[0169] According to a second aspect of the present invention, there is provided a vacuum cleaner including the cleaning assembly 100 provided in any of the above embodiments, and thus having all the beneficial technical effects of the cleaning assembly 100, which will not be elaborated herein.

[0170] Optionally, the vacuum cleaner includes a fan assembly and a connecting pipe assembly. The two ends of the connecting pipe assembly are respectively communicated with the fan assembly and the accommodating cavity 111. When the fan assembly is in a working state, it can generate a suction airflow, so as to provide suction when the user operates the cleaning assembly 100 to clean the surface to be cleaned, and achieve the dust suction effect of the vacuum cleaner.

[0171] Optionally, the vacuum cleaner includes a handheld rechargeable vacuum cleaner or a floor sweeping robot.

[0172] In the description of this specification, terms such as "connection", "installation", and "fixation" should all be understood in a broad sense.
