[0004] However, roller brushes are prone to getting tangled in hair during the cleaning process, which affects their cleaning function. Utility Model Content
[0005] This application provides a cleaning device to solve the technical problem that current roller brushes are easily entangled with hair during the cleaning process, which affects the cleaning function.
[0006] This application provides a cleaning device, including a device body, a roller brush, and a base plate; the device body has an air inlet and a roller brush chamber, the roller brush chamber is connected to the air inlet, and the roller brush is rotatably disposed in the roller brush chamber; the base plate covers the side of the roller brush chamber facing the surface to be cleaned; the base plate includes a plurality of support ribs, each support rib having at least one connecting portion, the inner wall of the connecting portion and the outer surface of the support rib having a height difference; when the air inlet draws in airflow through the roller brush chamber, the airflow flowing through the outer surface of the support rib and the airflow flowing through the connecting portion have a velocity difference.
[0007] The cleaning device provided in this application has a base plate covering the roller brush chamber. The support ribs on the base plate are located at the opening of the roller brush chamber. When the air intake is drawing air, the connecting part on the support rib can cause disturbance to the airflow, preventing hair from being drawn into the roller brush chamber and directly contacting the roller brush, thus preventing it from getting tangled in the roller brush.
[0008] As an optional implementation, the base plate includes a frame that surrounds the open edge of the brush cavity, and the two ends of the support rib are respectively connected to the two sides of the frame; the connecting portion extends through the support rib along its width direction.
[0009] This design, with its frame and supporting ribs forming the skeleton structure of the base plate, improves the structural strength of the cleaning equipment.
[0010] As an optional implementation, multiple support ribs are arranged at intervals along the length of the brush cavity.
[0011] This configuration, with multiple parallel support ribs, further enhances the structural strength at the brush cavity opening.
[0012] As an optional implementation, the connecting part includes a through groove, and the groove walls on both sides of the through groove are chamfered.
[0013] This design, with its chamfered edges, can disrupt airflow and prevent hair from getting tangled in the roller brush.
[0014] As an optional implementation, the chamfer is inclined towards the bottom wall of the through groove, and the width of the bottom wall of the through groove is greater than the width of the top wall of the through groove.
[0015] With this configuration, when the air intake draws in air, the airflow flowing over the outer surface of the support rib and the airflow flowing over the connecting part have a velocity difference, which can create turbulence in the airflow and reduce the chance of hair directly contacting the roller brush.
[0016] As an optional implementation, the cross-sectional area of the through groove is 1%-90% of the area of the bottom plate.
[0017] This design allows for control over the degree of airflow disturbance caused by the through-slot, thereby preventing hair from tangling around the roller brush.
[0018] As an optional implementation, the connecting part includes a through hole, and the supporting rib is provided with at least one through hole, the through hole being used to disturb the airflow of the air intake.
[0019] This design allows the airflow at the air intake to be disturbed through the through-hole, preventing hair from getting tangled.
[0020] As an optional implementation, the support rib extends along the width direction of the base plate, and the two ends of the support rib are respectively connected to the two side edges of the base plate in the width direction.
[0021] With this configuration, the support ribs extend along the width of the floor, shortening the length of a single support rib and improving support stability.
[0022] As an optional implementation, the brush cavity extends along the width direction of the main body of the equipment, and the length of the brush cavity matches the width of the main body of the equipment; the base plate extends along the width direction of the main body of the equipment, and the length of the base plate matches the length of the brush cavity.
[0023] With this configuration, the base plate can support the brush cavity along the width of the main body of the equipment, thereby improving the structural stability of the brush cavity.
[0024] As an optional implementation, the ratio of the area of the base plate to the area of the bottom wall of the equipment body is 50%-80%.
[0025] This design ensures the structural strength of the bottom of the cleaning equipment while reducing its weight and improving portability.
[0026] As an optional implementation, the frame of the base plate is provided with multiple ventilation holes, which are arranged at intervals along the inner or outer edge of the frame of the base plate; and / or, the bottom wall of the equipment body is provided with multiple ventilation holes, which connect the roller brush cavity and the bottom space of the equipment body.
[0027] With this setup, when the air intake is drawing in air, dust, hair, and other debris can be quickly sucked in through the ventilation holes, improving cleaning efficiency.
[0028] As an optional implementation, the cleaning device also includes a bottom shell, which covers the side of the device body facing the surface to be cleaned; the side of the bottom shell facing the surface to be cleaned has multiple ventilation slots for guiding airflow.
[0029] With this design, when the air intake is drawing in air, the ventilation slot can guide the airflow at the bottom of the casing, allowing dust, hair, and other debris to be quickly drawn in, thus improving cleaning efficiency.
[0030] This application provides a cleaning device, including a device body, a roller brush, and a base plate. The device body has an air inlet and a roller brush chamber, the roller brush chamber being connected to the air inlet, and the roller brush being rotatably disposed in the roller brush chamber. The base plate covers the side of the roller brush chamber facing the surface to be cleaned. The base plate includes a plurality of support ribs, each support rib having at least one connecting portion, the inner wall of the connecting portion having a height difference with the outer surface of the support rib. When the air inlet draws air in through the roller brush chamber, the airflow flowing through the outer surface of the support rib and the airflow flowing through the connecting portion have a velocity difference, which causes turbulence in the airflow near the opening of the roller brush chamber, reducing the probability of hair contacting the roller brush and preventing hair from tangling around the roller brush.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0044] Vacuum cleaners, floor scrubbers, mite removers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment maintains a clean and tidy living and working environment through various functions such as vacuuming and mopping.
[0045] In related technologies, cleaning equipment typically uses a roller brush to scrub or pat the surface to be cleaned, and sucks in dust, hair and other debris through an air intake to clean the surface.
[0046] However, when the roller brush rotates at high speed, it will cause airflow to rotate around the roller brush. The airflow will cause hair fibers to gradually wrap around the roller brush. When there are too many hair fibers wrapped around, they will hinder the rotation of the roller brush and affect the cleaning effect.
[0047] To solve the above-mentioned technical problems, this application provides a cleaning device. The cleaning device has a bottom plate covering the roller brush cavity. The support ribs on the bottom plate are located at the opening of the roller brush cavity. When the air intake is drawing air, the connecting part on the support rib can cause disturbance to the airflow, preventing hair from being drawn into the roller brush cavity and directly contacting the roller brush, and from rotating with the roller brush and then wrapping around the roller brush.
[0048] The following is an example illustrating the application scenarios of the cleaning equipment provided in the embodiments of this application.
[0049] The applicable product types provided in this application embodiment may include, but are not limited to, vacuum cleaners, mite removers, etc. Depending on the product type, the cleaning equipment provided in this application embodiment can be used to clean hard surfaces of various materials, such as floors and tiles, and can also be used to clean soft surfaces of various materials, such as sofas and carpets. This application embodiment does not make specific limitations in this regard.
[0050] Figure 1 This is a schematic diagram of the bottom structure of the cleaning device provided in the embodiments of this application; Figure 2 This is a schematic diagram of the structure of the base plate of the cleaning equipment provided in the embodiments of this application; Figure 3 for Figure 2 A schematic diagram of the AA cross-section; Figure 4 This is a schematic diagram of a ventilation slot provided in an embodiment of this application.
[0051] See Figures 1 to 3As shown, this application embodiment provides a cleaning device, including a device body 100, a roller brush 200, and a base plate 300; the device body 100 has an air intake and a roller brush cavity 110, the roller brush cavity 110 is connected to the air intake, and the roller brush 200 is rotatably disposed in the roller brush cavity 110; the base plate 300 covers the side of the roller brush cavity 110 facing the surface to be cleaned; the base plate 300 includes a plurality of support ribs 310, each support rib 310 having at least one connecting portion, the inner wall of the connecting portion having a height difference with the outer surface of the support rib 310; when the air intake draws in airflow through the roller brush cavity 110, the airflow flowing through the outer surface of the support rib 310 has a velocity difference with the airflow flowing through the connecting portion.
[0052] Understandably, the roller brush 200 has a striking part protruding from the roller brush cavity 110. When the cleaning equipment is cleaning, the striking part of the roller brush 200 can strike the surface to be cleaned, making it easier to separate dust, hair and other debris from the surface. At the same time, the air intake is used to draw air, and the airflow flows from the cavity of the roller brush cavity 110 to the air intake, and carries dust, hair and other debris into the air intake. Finally, the debris is collected in the waste collection device inside the main body 100 of the equipment.
[0053] It should be noted that the main body 100 of the equipment is equipped with a suction unit, which is connected to the motor. The suction unit is connected to the suction port through the suction channel inside the main body 100 of the equipment. When the suction unit is turned on, the suction port generates negative pressure suction. Since the suction port is connected to the roller brush chamber 110, the opening of the roller brush chamber 110 faces the surface to be cleaned and is close to the surface to be cleaned, so that the garbage and debris on the surface to be cleaned facing the opening of the roller brush chamber 110 can be sucked into the suction port through the roller brush chamber 110.
[0054] Understandably, since the base plate 300 covers the roller brush cavity 110, when the air intake is drawing air, the external air flows from the cavity opening of the roller brush cavity 110 to the air intake and passes through the support ribs 310 on the base plate 300. Since the support ribs 310 have a connecting part, there is a height difference between the inner wall of the connecting part and the outer surface of the support ribs 310. When the airflow flows through the support ribs 310, the airflow flowing through the outer surface of the support ribs 310 and the airflow flowing through the connecting part will generate a velocity difference, which will then cause turbulence. Multiple support ribs 310 will disturb the airflow near the cavity opening of the air intake cavity, suppressing the centripetal force generated by the rotation of the roller brush 200 from causing hair to wrap around the roller brush 200, reducing the probability of hair and fibers directly contacting the beating part of the roller brush 200. While preventing the roller brush 200 from wrapping hair, it can remove hair and fibers from the surface to be cleaned.
[0055] Each support rib 310 has one or more connecting portions. For example, the number of connecting portions of each support rib 310 can be 1, 2, 3, 4, 5, etc., and this application embodiment does not make a specific limitation. Multiple connecting portions can be arranged along the length direction of the support rib 310. While ensuring the support strength, multiple connecting portions can enhance the disturbance effect on the airflow at the cavity opening of the roller brush cavity 110, and can reduce the weight of the reinforcing rib, achieving a certain weight reduction effect.
[0056] As one possible implementation, the base plate 300 includes a frame 320, which surrounds the open edge of the roller brush cavity 110, and the two ends of the support rib 310 are respectively connected to the two sides of the frame 320; the connecting part is provided through the width direction of the support rib 310.
[0057] Reference Figure 1 The direction of movement of the cleaning equipment during cleaning is defined as the Y direction, and the width direction of the main body of the equipment is defined as the X direction, which is perpendicular to the Y direction.
[0058] It should be noted that the length direction of the support rib 310 is the direction of movement of the cleaning equipment during cleaning, i.e., the Y direction; the width direction of the support rib 310 is the width direction of the main body 100 of the equipment, i.e., the X direction.
[0059] Understandably, the base plate 300 includes a frame 320 with an opening in the middle. The shape and size of the opening in the middle of the frame 320 can match the opening of the brush cavity 110. The frame 320 is set around the edge of the opening of the brush cavity 110. The connection between the frame 320 and the edge of the opening of the brush cavity 110 can be a snap-fit connection, adhesive bonding, or integral molding. The two ends of the support rib 310 are respectively connected to the two sides of the frame 320. The connection between the support rib 310 and the frame 320 can be welding or integral molding. The connecting part is set through the width direction of the support rib 310. The airflow direction in the connecting part can be parallel to the X direction or at a non-90° angle to the X direction.
[0060] As one possible implementation, multiple support ribs 310 are arranged at intervals along the length of the brush cavity 110.
[0061] It should be noted that the length direction of the roller brush cavity 110 is the width direction of the main body 100 of the equipment, that is, the X direction.
[0062] Understandably, multiple support ribs 310 can prevent the roller brush cavity 110 from deforming when the roller brush 200 is running at high speed or when the roller brush cavity 110 is under pressure. The support ribs 310 have an arc shape and protrude towards the surface to be cleaned. The arc shape of the support ribs 310 can further disturb the airflow at the cavity opening of the roller brush cavity 110 and prevent hair fibers from getting tangled.
[0063] It should be noted that the multiple support ribs 310 can be arranged in parallel intervals along the length of the brush cavity 110, or they can be arranged in non-parallel intervals, or some support ribs 310 can be arranged at intervals and some support ribs 310 can be arranged crosswise.
[0064] For example, the support rib 310 can be made of metal, such as aluminum, or wear-resistant engineering plastics.
[0065] It should be noted that the tapping part on the surface of the roller brush 200 can adopt an alternating convex structure, with the convex part extending out of the support rib 310 to contact the surface to be cleaned, and the concave part being covered by the support rib 310.
[0066] Reference Figure 3 , combined Figure 1 and Figure 2 In some embodiments, the connecting portion includes a through groove 311, and the groove walls on both sides of the through groove 311 are provided with chamfers 312.
[0067] It is understandable that when the air intake is drawing air, part of the airflow flows through the through groove 311. By setting a specific angled inclined structure in the through groove 311, i.e. setting a specific angled chamfer 312, turbulence can be induced. When the airflow passes through the chamfer 312, the geometric change leads to an increase in the velocity gradient, breaking the laminar boundary layer and generating directional vortices, such as longitudinal vortices or Karman vortex streets. These vortices enhance the lateral mixing ability of the airflow through shearing and energy transfer, which can disturb the surrounding airflow and reduce the probability of hair fibers contacting the roller brush 200, thereby preventing hair fibers from getting tangled in the roller brush 200.
[0068] It should be noted that the chamfers 312 on both sides of the through groove 311 can be symmetrical or asymmetrical. The inclination angle of the chamfers 312 on both sides of the through groove 311 is in the range of 0°-90°. In some embodiments, the two sides of the through groove 311 can be directly connected to the top wall 311b and the bottom wall 311a of the through groove 311.
[0069] For example, the chamfer angle 312 can be 15°, 30°, 45°, 60°, 75°, etc., and this application embodiment does not make specific limitations.
[0070] Continue to refer to Figure 3 , combined Figure 1 and Figure 2In some embodiments, the chamfer 312 is inclined toward the bottom wall 311a of the through groove 311. The width of the bottom wall 311a of the through groove 311 is greater than the width of the top wall 311b of the through groove 311. The through groove 311 forms a fan-shaped structure that is narrow at the top and wide at the bottom. When the airflow flows through the support rib 310, a significant velocity difference is formed between the airflow outside the support rib 310 and the airflow inside the through groove 311. When the airflow outside the support rib 310 and the airflow inside the through groove 311 merge, turbulence is formed, which can disturb the surrounding airflow and reduce the probability of hair fibers contacting the roller brush 200, thereby preventing hair fibers from getting tangled in the roller brush 200.
[0071] As one possible implementation, the cross-sectional area of the through groove 311 is 1%-90% of the area of the base plate 300. The degree of disturbance of the through groove to the airflow can be controlled by controlling the cross-sectional area of the through groove. The disturbance of the through groove to the airflow needs to ensure that hair will not get tangled in the roller brush 200, and the degree of disturbance should not be too large, so as not to affect the absorption efficiency of the air intake for garbage and debris.
[0072] For example, the ratio of the cross-sectional area of the through groove 311 to the area of the base plate 300 can be 1%, 5%, 10%, 50%, 90%, etc., and this application embodiment does not make specific limitations.
[0073] In some embodiments, the connecting portion includes a through hole, and the support rib 310 is provided with at least one through hole. The hole wall of the through hole may be provided with protruding points and recessed points. When the airflow flows through the through hole, it will generate eddies, thereby disturbing the airflow near the support rib 310 and reducing the probability of hair fibers directly contacting the roller brush 200.
[0074] As one possible implementation, the support rib 310 extends along the width direction of the base plate 300, and the two ends of the support rib 310 are respectively connected to the two side edges of the base plate 300 in the width direction.
[0075] It should be noted that the width direction of the base plate 300 is the direction of movement of the cleaning equipment during cleaning, i.e., the Y direction; the length direction of the base plate 300 is the width direction of the main body 100 of the equipment, i.e., the X direction.
[0076] It is understandable that the support rib 310 connects the two ends of the base plate 300 in the width direction, that is, connects the two side frames 320 of the base plate 300 in the width direction. This can shorten the length of the support rib 310 and increase the support stability. Multiple parallel support ribs 310 can distribute the concentrated load to both sides of the base plate 300 and reduce the risk of local deformation.
[0077] As one possible implementation, the roller brush cavity 110 extends along the width direction of the equipment body 100, and the length of the roller brush cavity 110 matches the width of the equipment body 100; the base plate 300 extends along the width direction of the equipment body 100, and the length of the base plate 300 matches the length of the roller brush cavity 110.
[0078] Understandably, when the cleaning equipment moves along the cleaning direction, the length of the roller brush cavity 110 matches the width of the main body 100, allowing the cleaning range of the roller brush cavity 110 to cover the moving path of the main body 100, preventing cleaning omissions and reducing repeated cleaning. Since the length of the base plate 300 matches the length of the roller brush cavity 110, the frame 320 and support ribs 310 of the base plate 300 can fix and support the entire roller brush cavity 110, increasing structural stability.
[0079] As one possible implementation, the ratio of the area of the base plate 300 to the area of the bottom wall of the main body 100 of the equipment is 50%-80%. The base plate 300 is used to improve the structural strength of the roller brush cavity 110. If the area is too small, it will be difficult to provide sufficient structural strength. If the area is too large, it will increase the total weight of the machine. When the ratio is 50%-80%, the weight of the equipment can be reduced while ensuring the structural strength of the bottom of the cleaning equipment, thus improving portability.
[0080] For example, the ratio of the area of the base plate 300 to the area of the bottom wall of the equipment body 100 can be 50%, 55%, 60%, 70%, 79%, 80%, etc., and this application embodiment does not make specific limitations.
[0081] Reference Figure 1 As one possible implementation, the frame 320 of the base plate 300 is provided with a plurality of ventilation holes 321, which are arranged at intervals along the inner or outer edge of the frame 320 of the base plate 300; and / or, the bottom wall of the equipment body 100 is provided with a plurality of ventilation holes 321, which connect the roller brush cavity 110 and the bottom space of the equipment body 100.
[0082] It is understood that multiple ventilation holes 321 can be set on the frame 320 of the base plate 300, or on the bottom wall of the main body 100, or simultaneously on the frame 320 of the base plate 300 and the bottom wall of the main body 100. The ventilation holes 321 can connect the roller brush chamber 110 and the external space of the main body 100, so that garbage and debris can enter the roller brush chamber 110 through the ventilation holes 321, thereby increasing the suction efficiency of garbage and debris. When the ventilation holes 321 are set on the frame 320 of the base plate 300, they can be set on the inner edge of the frame 320, or on the outer edge of the frame 320, or simultaneously on the inner and outer edges of the frame 320.
[0083] For example, the cross-section of the ventilation hole 321 can be circular or semi-circular. Multiple ventilation holes 321 are arranged in a serrated pattern along the inner edge of the frame 320 of the base plate 300. When the suction port draws air, debris is sucked in from the roller brush chamber 110, and when debris is near the frame 320 of the base plate 300, it can be quickly sucked in through the ventilation holes 321. Since the suction port and the roller brush chamber 110 are connected, the open area of the roller brush chamber 110 is consistent with the suction range of the cleaning equipment. By adding ventilation holes 321, the suction range of the roller brush chamber 110 can be increased, thereby increasing cleaning efficiency.
[0084] Reference Figure 4 As one possible implementation, the cleaning device also includes a bottom shell 400, which covers the side of the device body 100 facing the surface to be cleaned; the side of the bottom shell 400 facing the surface to be cleaned has multiple ventilation slots 410, which are used to guide airflow.
[0085] Understandably, the bottom shell 400 has multiple protrusions, and the gaps between these protrusions form ventilation slots 410, which can create a gas flow path. When the cleaning equipment moves and cleans the surface to be cleaned, the airflow at the bottom of the bottom shell 400 flows along the ventilation slots 410, accelerating the gas flow rate. Debris at the bottom of the bottom shell 400 can be carried by the airflow and quickly drawn into the roller brush chamber 110 along the ventilation slots 410, then enters the suction port through the roller brush chamber 110, and finally is carried into the collection device by the airflow.
[0086] It should be noted that the ventilation slots 410 can be staggered along the width direction of the main body 100 and the cleaning direction of the cleaning equipment. The staggered ventilation slots 410 are interconnected and can be perpendicular or not perpendicular to each other. The ventilation slots 410 arranged along the cleaning direction are connected to the roller brush cavity 110. When the air intake is drawing air, the airflow can enter the ventilation slots 410 from around the bottom shell 400, flow along the width direction of the main body 100 and the cleaning direction of the cleaning equipment, and finally converge into the roller brush cavity 110.
[0087] The ventilation slot 410 can be arranged to overlap with the ventilation hole 321, so that the garbage and debris in the ventilation slot 410 can enter the roller brush cavity 110 through the ventilation hole 321. Alternatively, the ventilation slot 410 can be arranged to intersect with the ventilation hole 321, so that the garbage and debris in the ventilation slot 410 can directly enter the roller brush cavity 110.
[0088] This application provides a cleaning device, including a device body 100, a roller brush 200, and a base plate 300. The device body 100 has an air intake and a roller brush cavity 110, the roller brush cavity 110 being connected to the air intake, and the roller brush 200 being rotatably disposed in the roller brush cavity 110. The base plate 300 covers the side of the roller brush cavity 110 facing the surface to be cleaned. The base plate 300 includes a plurality of support ribs 310, each support rib 310 having at least one connecting portion, the inner wall of the connecting portion having a height difference with the outer surface of the support rib 310. When the air intake draws air through the roller brush cavity 110, the airflow flowing through the outer surface of the support rib 310 and the airflow flowing through the connecting portion have a velocity difference, which causes turbulence in the airflow near the opening of the roller brush cavity 110, reducing the probability of hair contacting the roller brush 200 and preventing hair from tangling around the roller brush 200.
