Description

Technical Field

[0001] This application relates to the technical field of cleaning products, and particularly to a cleaning device. Background Art

[0002] Cleaning devices such as mite removers, vacuum cleaners, and floor sweeping robots are commonly used in households. Vacuum cleaners and floor sweeping robots can clean the floor, and mite removers can remove dust and mites on the surface of mattresses, leather, etc.

[0003] In related technologies, a cleaning device generally includes a housing and a fan unit disposed inside the housing. The airflow generated by the fan unit creates suction at the air suction port of the housing. A rotary brush may be disposed at a position corresponding to the air suction port. The rotary brush rolls on the surface to be cleaned to pick up dust and hair, and the dust and hair are sucked into the device through the suction of the air suction port, thereby achieving the cleaning function.

[0004] However, during the cleaning process of current cleaning devices, hair is easily wound around the rotary brush and cannot be sucked into the device. Summary of the Utility Model

[0005] This application provides a cleaning device to solve the technical problem that during the cleaning process of current cleaning devices, hair is easily wound around the rotary brush and cannot be sucked into the device.

[0006] This application provides a cleaning device, which includes a device main body and a rotary brush assembly. The rotary brush assembly is connected to the device main body; the rotary brush assembly includes a plurality of cleaning segments sequentially connected in a first direction; the device main body has an air suction port, and the air suction port is located on the axial side of the rotary brush assembly.

[0007] Among them, at least one of the plurality of cleaning segments is opposite to the air suction port; the outer contour diameter of the cleaning segment opposite to the air suction port is smaller than the outer contour diameters of the other cleaning segments.

[0008] By the differential design of the outer contour diameter of the rotary brush assembly provided in the embodiments of this application, the rotary brush assembly has a relatively smaller outer contour diameter at the position opposite to the air suction port. When the rotary brush assembly rotates, the hair rolled up by the rotary brush assembly will gather towards the position close to the air suction port and is more easily sucked into the air suction port, rather than being wound tighter and tighter on the rotary brush assembly, which is more convenient for cleaning the rotary brush assembly.

[0009] As an optional implementation manner, the outer contour diameters at both ends of the cleaning segment opposite to the air suction port in the first direction are greater than the outer contour diameter at the middle of the cleaning segment in the first direction.

[0010] With such a setting, when the rotary brush assembly rolls, the hair rolled up at the position opposite to the air suction port will gather towards the middle of this cleaning segment, improving the efficiency of hair suction.

[0011] As an alternative embodiment, the outer contour diameter of the cleaning section opposite to the suction port gradually decreases from both ends in the first direction towards the middle.

[0012] With such a setting, even if there is hair wrapped around the roller brush assembly, it will tighten and slide along the direction in which the outer contour diameter of the cleaning section decreases, thus gathering in the middle of the cleaning section, making it more convenient to clean.

[0013] As an alternative embodiment, the plurality of cleaning sections may include a first cleaning section and two second cleaning sections, and the two second cleaning sections are connected to both ends of the first cleaning section in the first direction; the first cleaning section is opposite to the suction port, an inhalation area is formed between the first cleaning section and the suction port, there is a gap between the side of the second cleaning section and the device main body, and the width of the inhalation area is greater than the width of the gap.

[0014] With such a setting, the hair rolled up by the roller brush assembly can gather towards the middle first cleaning section, and will not slide towards the second cleaning sections at both ends, avoiding the hair from winding around the rotating shafts at both ends of the roller brush assembly.

[0015] As an alternative embodiment, the length of the first cleaning section in the first direction is greater than or equal to the length of the suction port in the first direction; and / or, the projection of the suction port in the second direction is within the projection range of the first cleaning section in the second direction, where the second direction is perpendicular to the first direction.

[0016] With such a setting, the first cleaning section can be made to face or approximately face the suction port, so that the hair rolled up and gathered on the first cleaning section can be sucked into the suction port, improving the cleaning efficiency.

[0017] As an alternative embodiment, the outer contour diameters of the two second cleaning sections are equal; the two second cleaning sections are symmetric with respect to the center line or centrosymmetric with respect to the first cleaning section.

[0018] With such a setting, it is possible to avoid excessive hair being rolled up at one end during the rotational cleaning of the roller brush assembly, resulting in winding and jamming.

[0019] As an alternative embodiment, the roller brush assembly may include a drum and a flexible cleaning member, the axial direction of the drum extends along the first direction, the outer wall of the drum is provided with a slot, and the flexible cleaning member is inserted into the slot; at least part of the structure of the flexible cleaning member extends radially outward of the slot along the drum.

[0020] With such a setting, when the roller brush assembly rotates, the flexible cleaning member can beat the surface to be cleaned, thereby lifting dust and hair and improving the cleaning effect.

[0021] As an alternative embodiment, the flexible cleaning member extends along the axial direction of the drum; or, the flexible cleaning member extends spirally along the circumferential outer wall of the drum.

[0022] With such a setting, flexible cleaning members can contact the surface to be cleaned along the axial direction of the rotary brush assembly, increasing the cleaning range.

[0023] As an alternative embodiment, the slot runs through both ends of the drum along the first direction; a clamping groove is provided at one end of the slot facing the axis of the drum, and the cross-sectional width of the clamping groove is greater than that of the slot; a clamping protrusion is provided at one end of the flexible cleaning member facing the axis of the drum, and the clamping protrusion is clamped with the clamping groove.

[0024] With such a setting, the reliability of the installation of the flexible cleaning member on the drum can be improved, and the flexible cleaning member can be prevented from falling off the drum.

[0025] As an alternative embodiment, the rotary brush assembly may further include an end cap, and the end cap is connected to the end of the drum along the first direction; at least part of the end cap is arranged to block the end of the flexible cleaning member.

[0026] With such a setting, the axial sliding of the flexible cleaning member can be restricted, and the installation stability of the flexible cleaning member can be improved.

[0027] As an alternative embodiment, the device main body may include a base and a cover plate. The base has a receiving groove, and the rotary brush assembly is rotatably arranged in the receiving groove. The cover plate covers the notch of the receiving groove; a dirt inlet groove is provided on the side of the cover plate away from the suction port.

[0028] With such a setting, the dirt inlet groove can guide the hair and dust lifted by the rotary brush assembly, improving the cleaning efficiency.

[0029] As an alternative embodiment, the cover plate may be provided with an opening, and the rotary brush assembly protrudes at least partially out of the receiving groove through the opening; at least two blocking ribs are provided on the cover plate, and the at least two blocking ribs are spaced along the first direction, and both ends of the blocking ribs are respectively connected to both sides of the opening.

[0030] With such a setting, when cleaning a flexible surface to be cleaned such as a bedsheet, the fabric can be prevented from being sucked into the rotary brush, ensuring the smoothness of the cleaning process.

[0031] As an alternative embodiment, the blocking rib is opposite to the suction port; and / or, the distance between adjacent blocking ribs is 30 mm - 50 mm.

[0032] With such a setting, the fabric can be effectively prevented from being sucked into the suction port, causing the cleaning process to stagnate.

When the roller brush assembly rotates, the hair rolled up by the roller brush assembly will gather towards the position close to the suction port and is more easily sucked into the suction port, rather than becoming more and more tightly wound on the roller brush assembly, which is more convenient for cleaning the roller brush assembly.

[0046] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, or an indirect connection through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0047] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0048] The terms "first", "second", "third" (if any) in the description, claims and drawings of the present application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0049] In addition, the terms "including" and "having" and any variations thereof are intended to cover non - exclusive inclusion. For example, a process, method, system, product or maintenance tool that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or maintenance tools.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.

[0051] A cleaning device generally includes a housing and a blower unit disposed within the housing. The airflow generated by the blower unit creates suction at the air intake of the housing. A roller brush may be provided at a position corresponding to the air intake. The roller brush rolls on the surface to be cleaned to pick up dust and hair, and the dust and hair are sucked into the device through the suction of the air intake, thereby realizing the cleaning function.

[0052] However, during the cleaning process of current cleaning devices, hair is easily wound around their roller brushes and cannot be sucked into the device. Taking a mite remover as an example, a mite remover can remove dust and mites on the surfaces of beddings, leather materials, etc. There is usually a lot of hair adhered to the beddings. When the roller brush of the mite remover rolls on the surface of the bedding, the hair is easily wound around the roller brush. And as the roller brush rolls, the wound hair will become tighter and tighter towards both ends of the roller brush and cannot be sucked away. This will also make the cleaning of the roller brush time-consuming and laborious.

[0053] To solve the above technical problems, the embodiments of this application provide a cleaning device. Through the design of the overall structure of the roller brush, a narrowed contour structure is formed in the area of the roller brush opposite to the air intake. When the roller brush rolls up the hair, the hair will not wind and tighten at a specific position on the roller brush or towards both ends of the roller brush, but will wind and move towards the narrowed area as the roller brush rotates, and be sucked into the device under the suction of the air intake, reducing the amount of hair wound around the roller brush, improving the cleaning efficiency, and making it more convenient to clean the roller brush after cleaning.

[0054] First, the application scenarios of the cleaning device provided by the embodiments of this application will be illustrated by examples.

[0055] The cleaning device provided by the embodiments of this application is a cleaning tool with a roller brush structure. Specifically, the product types of the cleaning device in the embodiments of this application may include but are not limited to mite removers, vacuum cleaners, floor sweepers, floor cleaning robots, etc. According to different product types, the cleaning device provided by the embodiments of this application can be used to clean floors, clothes, quilts, sofa furniture, etc. The embodiments of this application do not make specific limitations on this.

[0056] Figure 1 is a schematic diagram of the setting of the roller brush assembly in the cleaning device provided by the embodiments of this application; Figure 2 is a schematic structural diagram of the roller brush assembly of the cleaning device provided by the embodiments of this application.

[0057] See Figure 1 and Figure 2 As shown, the present application provides a cleaning device 10, which includes a device main body 100 and a rotary brush assembly 200. The rotary brush assembly 200 is connected to the device main body 100. When the cleaning device 10 performs a cleaning operation, the side of the device main body 100 connected to the rotary brush assembly 200 faces the surface to be cleaned. The rotary brush assembly 200 can contact the surface to be cleaned. As the device main body 100 moves, the rotary brush assembly 200 rolls on the surface to be cleaned, and the rotary brush assembly 200 can pick up impurities such as dust and hair on the surface to be cleaned, making it easier for the dust and hair and other impurities to be sucked into the interior of the device main body 100.

[0058] Among them, the rotary brush assembly 200 includes a plurality of cleaning segments 201 connected in sequence along a first direction. The device main body 100 has a suction port 101, and the suction port 101 is located on the axial side of the rotary brush assembly 200. At least one of the plurality of cleaning segments 201 is opposite to the suction port 101.

[0059] Define the first direction as the X direction. The first direction is the length direction of the rotary brush assembly 200, that is, the first direction is the axial direction of the rotation of the rotary brush assembly 200. The plurality of cleaning segments 201 correspond to different positions in the length direction of the rotary brush assembly 200 in sequence.

[0060] It can be understood that when the cleaning device 10 performs a cleaning operation, the plurality of cleaning segments 201 can contact the surface to be cleaned at the same time. As the rotary brush assembly 200 rolls, the plurality of cleaning segments 201 pick up dust and hair at different positions on the surface to be cleaned at the same time. The suction port 101 can generate suction on the side of the rotary brush assembly 200, and suck the dust and hair picked up by each cleaning segment 201 into the interior of the device main body 100. The suction force in the area where the cleaning segment 201 opposite to the suction port 101 is located is greater than that of the cleaning segments 201 in other positions not opposite to the suction port 101. The hair picked up by the cleaning segment 201 opposite to the suction port 101 is more easily sucked into the suction port 101.

[0061] In some embodiments, the outer contour diameter of the cleaning segment 201 opposite to the suction port 101 is smaller than the outer contour diameters of the other cleaning segments 201. When each cleaning segment 201 rolls up the hair, as the hair is wound, the hair will converge or slide towards the cleaning segment 201 with a smaller outer contour diameter, that is, the rolled-up hair will converge or move towards the cleaning segment 201 opposite to the suction port 101, and thus is more easily sucked into the suction port 101.

[0062] Among them, when the cleaning segment 201 rotates around its own axis, the radial cross-section of the formed rotating body is circular. The outer contour diameter of the cleaning segment 201 refers to the diameter of the radial cross-section of the rotating body formed when the cleaning segment 201 rotates around its axis.

[0063] It can be understood that the suction port 101 can be located at the rear side of the roller brush assembly 200 along the cleaning direction of the cleaning device 10, and the first direction is perpendicular to the cleaning direction of the cleaning device 10. At least one of the plurality of cleaning segments 201 being opposite to the suction port 101 means that at least one cleaning segment 201 is opposite to the suction port 101 in the cleaning direction of the cleaning device 10. The other cleaning segments 201 that are not opposite to the suction port 101 are misaligned with the suction port 101 relative to the cleaning direction of the cleaning device 10.

[0064] The length of the roller brush assembly 200 formed by sequentially connecting the plurality of cleaning segments 201 along the first direction is relatively long, so as to have a larger cleaning coverage. The suction port 101 is opposite to some of the cleaning segments 201. In this way, the ventilation cross-sectional dimension of the suction port 101 can be controlled within a reasonable range to ensure the air intake flow rate of the air flow, so as to have a sufficiently large suction force to suck up dust and hair, and avoid insufficient suction due to the overly large suction port 101.

[0065] It should be noted that in the cleaning device 10 provided by the embodiments of the present application, the outer contour diameters of the plurality of cleaning segments 201 are designed differently, so that the roller brush assembly 200 has a relatively smaller outer contour diameter at the position opposite to the suction port 101. When the roller brush assembly 200 rotates, the hair rolled up by the roller brush assembly 200 will gather towards the position closer to the suction port 101 and is more easily sucked into the suction port 101, rather than becoming more and more tightly wound on the roller brush assembly 200, which is more convenient for cleaning the roller brush assembly 200.

[0066] It is easy for those skilled in the art to understand that when analyzing the force on the hair rolled up by the roller brush assembly 200, when there is a tendency for the hair to wind and tighten on the surface of the roller brush assembly 200, the surface of the roller brush assembly 200 will have a reaction force on the hair, and this reaction force is perpendicular to the surface of the roller brush assembly 200. Due to the difference in the outer contour diameter of the roller brush assembly 200 along its axial direction, this reaction force can be decomposed into a force perpendicular to the axial direction of the roller brush assembly 200 and a force parallel to the axial direction of the roller brush assembly 200. Among them, the force parallel to the axial direction of the roller brush assembly 200 points to the direction with a smaller outer contour diameter on the roller brush assembly 200. In this way, as the roller brush assembly 200 rotates, the rolled-up hair will move towards the cleaning segment 201 with a smaller outer contour diameter.

[0067] Figure 3 It is a side view of the roller brush assembly of the cleaning device provided by the embodiments of the present application.

[0068] Please refer to Figures 1 to 3, in some embodiments, the outer contour diameter of the cleaning section 201 opposite the air suction port 101 is greater at both ends in the first direction than at the middle in the first direction. In this way, at the position opposite the air suction port 101, the cleaning section 201 can form a structure with larger ends and a smaller middle.

[0069] It can be understood that when the roller brush assembly 200 rolls, the hair rolled up at the position opposite the air suction port 101 will gather towards the middle of the cleaning section 201. The convergence of the hair towards the middle can improve the efficiency of the hair being sucked into the air suction port 101 and prevent the hair from continuously winding and tightening on each cleaning section 201.

[0070] Exemplarily, the outer contour diameter of the cleaning section 201 opposite the air suction port 101 gradually decreases from both ends to the middle in the first direction. In the X direction, the cleaning section 201 opposite the air suction port 101 gradually narrows from both ends to the middle. In this way, even if there is hair wound around the roller brush assembly 200, it will tighten and slide along the direction of the decreasing outer contour diameter of the cleaning section 201, thus gathering in the middle of the cleaning section 201, which is more convenient for cleaning.

[0071] It should be noted that in the cleaning device 10 provided in the embodiments of the present application, the number of cleaning sections 201 of the roller brush assembly 200 can be two, three, four or more. Hereinafter, three cleaning sections 201 will be taken as an example for detailed description.

[0072] In a possible implementation manner, the multiple cleaning sections 201 may include a first cleaning section 201a and two second cleaning sections 201b, and the two second cleaning sections 201b are connected to both ends of the first cleaning section 201a in the first direction. The first cleaning section 201a is opposite the air suction port 101.

[0073] It can be understood that the outer contour diameter of the first cleaning section 201a is smaller than that of the second cleaning section 201b, so that the roller brush assembly 200 as a whole forms a structure with larger ends and a smaller middle. The air suction port 101 is opposite the middle position of the roller brush assembly 200. When the roller brush assembly 200 rotates, the rolled-up hair will be more likely to concentrate on the middle first cleaning section 201a, and thus is easily sucked into the air suction port 101, preventing a large amount of hair from winding around the roller brush assembly 200.

[0074] In some embodiments, an inhalation area 102 is formed between the first cleaning section 201a and the air suction port 101, and there is a gap between the side of the second cleaning section 201b and the device main body 100, and the width of the inhalation area 102 is greater than the width of the gap.

[0075] It can be understood that since the outer contour diameter of the first cleaning section 201a is smaller than that of the second cleaning sections 201b at both ends, there is a larger gap between the first cleaning section 201a and the device main body 100. A relatively large space can exist between the air suction port 101 and the first cleaning section 201a to form a suction area 102. The hair rolled up by the roller brush assembly 200 can gather towards the middle first cleaning section 201a and will not slide towards the second cleaning sections 201b at both ends, preventing the hair from winding around the rotating shafts at both ends of the roller brush assembly 200.

[0076] In some embodiments, the length of the first cleaning section 201a in the first direction is greater than or equal to the length of the air suction port 101 in the first direction. In this way, the first cleaning section 201a can have a relatively large length in the X direction to cover the air suction port 101, and the hair rolled up by the roller brush assembly 200 in a larger area in the X direction can more easily gather towards the air suction port 101.

[0077] In some embodiments, the projection of the air suction port 101 in the second direction is within the projection range of the first cleaning section 201a in the second direction, and the second direction is perpendicular to the first direction. Here, the second direction is the Y direction, and the Y direction is the cleaning direction of the cleaning device 10. In this way, the first cleaning section 201a can be directly opposite or as close as possible to the air suction port 101, so that the hair rolled up and gathered on the first cleaning section 201a can be sucked into the air suction port 101, improving the cleaning efficiency.

[0078] In some embodiments, the outer contour diameters of the two second cleaning sections 201b are equal. In this way, when the roller brush assembly 200 rolls and cleans on the surface to be cleaned, the frictional force generated between the roller brush assembly 200 and the surface to be cleaned is more balanced, preventing the frictional force difference at different positions of the roller brush assembly 200 in the X direction from being too large. This can improve the user's handling feel when pushing the device main body 100 to move.

[0079] Exemplarily, the two second cleaning sections 201b are symmetric or centrosymmetric with respect to the center line of the first cleaning section 201a, so as to prevent excessive hair from being rolled up at one end when the roller brush assembly 200 rotates and cleans, causing winding and jamming.

[0080] The following will describe the constituent structure of the roller brush assembly 200 in detail.

[0081] Figure 4 For Figure 3 the cross-sectional view in the A-A direction in Figure 5 For Figure 4 the cross-sectional view in the B-B direction in

[0082] Please refer to Figures 1 to 5, in a possible implementation, the roller brush assembly 200 may include a roller 210 and a flexible cleaning member 220. The axial direction of the roller 210 extends along the first direction. A slot 211 is provided on the outer wall of the roller 210, and the flexible cleaning member 220 is inserted into the slot 211. At least a part of the flexible cleaning member 220 extends radially outward of the roller 210 to the outside of the slot 211.

[0083] It can be understood that the roller 210, as the main structure of the roller brush assembly 200, plays a supporting role. The flexible cleaning member 220 can undergo elastic deformation when contacting the surface to be cleaned. When the roller brush assembly 200 rotates, the flexible cleaning member 220 can pat the surface to be cleaned, thereby raising dust and hair and improving the cleaning effect.

[0084] Exemplarily, the flexible cleaning member 220 can be one or a combination of a rubber strip, a brush, etc. For example, the flexible cleaning member 220 can be a rubber strip. When using a colloid as the flexible cleaning member 220, the rubber strip can pat the surface to be cleaned, and the hair will not be wound around the rubber strip. The hair lifted by the rubber strip is more likely to slide along the outer edge of the colloid towards the air suction port 101.

[0085] Exemplarily, the flexible cleaning member 220 extends along the axial direction of the roller 210. In this way, the flexible cleaning member 220 can contact the surface to be cleaned along the entire axial direction of the roller brush assembly 200, increasing the cleaning range.

[0086] Exemplarily, the flexible cleaning member 220 spirally extends along the outer circumferential wall of the roller 210. In this way, when the roller brush assembly 200 rolls along the cleaning direction of the cleaning device 10, different positions in the extending direction of the flexible cleaning member 220 can sequentially contact the surface to be cleaned as the roller brush assembly 200 rolls, ensuring that there is space for the air inlet of the air suction port 101 on the surface of the roller brush assembly 200 and improving the suction efficiency of dust and hair.

[0087] In some embodiments, the slot 211 penetrates through both ends of the roller 210 along the first direction. A clamping groove 212 is provided at one end of the slot 211 facing the axis of the roller 210. The cross-sectional width of the clamping groove 212 is greater than the cross-sectional width of the slot 211. A clamping protrusion 221 is provided at one end of the flexible cleaning member 220 facing the axis of the roller 210, and the clamping protrusion 221 is clamped with the clamping groove 212.

[0088] It is understandable that the extension slot 211 of the flexible cleaning member 220 extends from one axial end to the other end of the drum 210. When assembling the flexible cleaning member 220, the flexible cleaning member 220 can be inserted into the slot 211 from the axial end of the drum 210. The engagement protrusion 221 cooperates with the engagement slot 212 to limit the flexible cleaning member 220 in the radial direction of the drum 210, thereby improving the reliability of the installation of the flexible cleaning member 220 on the drum 210 and preventing the flexible cleaning member 220 from falling off the drum 210.

[0089] Exemplarily, the cross-sectional shape of the clamping groove 212 along the radial direction of the drum 210 matches the cross-sectional shape of the clamping protrusion 221. The cross-sectional shapes of the clamping groove 212 and the clamping protrusion 221 can be square, triangular, circular, elliptical or other polygonal structures, which is not specifically limited in the embodiment of the present application.

[0090] In some embodiments, the roller brush assembly 200 may further include an end cap 230, which is connected to the end of the roller 210 along the first direction. At least part of the end cap 230 is disposed at the end of the flexible cleaning member 220, thereby limiting the axial sliding of the flexible cleaning member 220 and improving the installation stability of the flexible cleaning member 220.

[0091] It is understandable that after the flexible cleaning member 220 is installed in the slot 211 on the drum 210 , end covers 230 can be installed at both axial ends of the drum 210 , and the end covers 230 can limit the flexible cleaning member 220 in the axial direction of the drum 210 .

[0092] Exemplarily, the end cap 230 may be circular in shape. The end cap 230 may be coaxially arranged with the drum 210, and the coverage area of the end cap 230 is larger than the end area of the drum 210, so that hair can be prevented from being rolled into the rollers at both ends of the drum 210.

[0093] The structure of the device body 100 and the assembly method of the roller brush assembly 200 on the device body 100 are described in detail below.

[0094] Figure 6 This is a schematic diagram of the structure of the equipment main body in the cleaning equipment provided in an embodiment of the present application.

[0095] Please refer to Figure 1 and Figure 6 In a possible implementation, the device body 100 may include a base 110 and a cover plate 120, the base 110 has a receiving groove 111, the roller brush assembly 200 is rotatably disposed in the receiving groove 111, and the cover plate 120 is disposed on the notch of the receiving groove 111. A dirt inlet groove 121 is provided on one side of the cover plate 120 away from the air inlet 101.

[0096] It is understandable that the notch of the accommodating groove 111 faces the bottom of the base 110, and the cover plate 120 is covered under the base 110, so that when the cleaning device 10 is in use, the flexible cleaning member 220 can face the surface to be cleaned under the base 110.

[0097] The dirt inlet 121 is located at the front side of the receiving groove 111 along the cleaning direction of the cleaning device 10, that is, the dirt inlet 121 is located at the front side of the device body 100 along the Y direction. When the cleaning device 10 performs a cleaning operation, the dirt inlet 121 can guide the hair and dust brought by the roller brush assembly 200 to improve the cleaning efficiency.

[0098] Exemplarily, the cover plate 120 may cover the area where the end caps 230 at both ends of the roller brush assembly 200 are located, thereby preventing hair from being rolled into the rotating shafts at both ends of the roller brush assembly 200 .

[0099] For example, the cover plate 120 can be connected to the base 110 by a snap, or connected by fasteners such as bolts. The cover plate 120 can be detachable relative to the base 110, or the cover plate 120 can be rotatably connected to the base 110 and can be rotated to open and close, which is not specifically limited in the embodiments of the present application.

[0100] In some embodiments, the cover plate 120 may be provided with an opening, and the roller brush assembly 200 at least partially protrudes out of the accommodating groove 111 through the opening. At least two retaining ribs 130 are provided on the cover plate 120, and the at least two retaining ribs 130 are spaced apart along the first direction, and the two ends of the retaining ribs 130 are respectively connected to the two sides of the opening.

[0101] It can be understood that the retaining rib 130 is arranged across the opening, and the retaining rib 130 can divide the opening into a plurality of small areas. This will not affect the contact between the flexible cleaning member 220 on the roller brush assembly 200 and the external surface to be cleaned, and dust and hair can smoothly enter the air suction port 101 driven by the roller brush assembly 200. On the other hand, when cleaning flexible surfaces to be cleaned such as bed sheets, cloth can be prevented from being sucked into the roller brush, thereby ensuring the smoothness of the cleaning process.

[0102] In some embodiments, the blocking rib 130 is opposite to the air suction port 101. Since the suction force on the surface to be cleaned is the greatest at the position opposite to the air suction port 101, the blocking rib 130 can be arranged at a position opposite to the first cleaning section 201a, that is, the blocking rib 130 is arranged at a position opposite to the air suction port 101, so as to better prevent the cloth from being sucked into the roller brush.

[0103] In some embodiments, the spacing between adjacent retaining ribs 130 is 30 mm-50 mm, which can effectively prevent the cloth from being sucked into the air suction port 101 and causing the cleaning process to stagnate.

[0104] Exemplarily, the number of the retaining ribs 130 may be two, three, four or more. Taking two retaining ribs 130 as an example, the two retaining ribs 130 straddle the opening along the Y direction, and the two retaining ribs 130 are spaced along the X direction. The distribution positions of the two retaining ribs 130 are opposite to the first cleaning section 201a. Since the outer contour diameter of the first cleaning section 201a is relatively small, when the brush roller assembly 200 rotates, interference between the flexible cleaning member 220 at the position of the first cleaning section 201a and the retaining ribs 130 can be avoided.

[0105] The cleaning device provided by the embodiment of the present application includes a device main body and a brush roller assembly, and the brush roller assembly is connected to the device main body; the brush roller assembly includes a plurality of cleaning sections sequentially connected along a first direction; the device main body has a suction port, and the suction port is located on the axial side of the brush roller assembly, and at least one of the plurality of cleaning sections is opposite to the suction port; the outer contour diameter of the cleaning section opposite to the suction port is smaller than that of the other cleaning sections. When the brush roller assembly rotates, the hair rolled up by the brush roller assembly will gather towards the position close to the suction port and is more easily sucked into the suction port, instead of becoming more and more entangled on the brush roller assembly, which is more convenient for cleaning the brush roller assembly.

[0106] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
