[0005] This application provides a cleaning device and equipment to solve the technical problem that current cleaning equipment often leaves behind hair, dust and other debris after cleaning, resulting in low cleaning efficiency.

[0006] In a first aspect, this application provides a cleaning device, which includes a device body, a roller brush, and a base plate; the device body has an air inlet and a roller brush cavity, the roller brush cavity is connected to the air inlet, and the roller brush is rotatably disposed in the roller brush cavity; the roller brush cavity is openly disposed facing the lower part of the device body, and the base plate is disposed on the edge of the open part of the roller brush cavity; the edge of the base plate is provided with a connecting part, the connecting part connecting the outer space of the roller brush cavity and the base plate.

[0007] The cleaning device provided in this application cleans the surface to be cleaned by scrubbing and patting the surface with a roller brush and sucking in hair, dust and other debris through an air inlet. The bottom plate covering the roller brush cavity has a connecting part, which can guide the airflow so that hair, dust and other debris can be quickly sucked in through the connecting part, thereby improving cleaning efficiency.

[0008] As an optional implementation, there are multiple connecting parts, which are arranged at intervals along the circumferential edge of the base plate.

[0009] This design allows for the rapid suction of debris from all directions around the base plate through multiple connecting sections, improving cleaning efficiency.

[0010] As an optional implementation, the connecting portion includes a connecting hole that extends through the thickness of the base plate.

[0011] This design allows the connecting hole to connect the outer space of the base plate with the inner space of the roller brush chamber, enabling debris to enter the roller brush chamber through the connecting hole and improving suction efficiency.

[0012] As an alternative implementation, the connecting hole can be a round hole, a semi-circular hole, or a polygonal hole.

[0013] This design increases the ventilation area of ​​the brush chamber through the connecting holes, thereby improving the suction efficiency.

[0014] As an optional implementation, the connecting part includes a connecting groove that extends through the width of the base plate; a bottom shell is provided under the main body of the device, and a ventilation groove is provided on the side of the bottom shell facing the surface to be cleaned, the ventilation groove connecting the peripheral space of the cleaning device and the connecting groove.

[0015] With this configuration, when the air intake is drawing air, the ventilation slots can guide the airflow, allowing debris to quickly enter the roller brush chamber through the ventilation slots and connecting slots, thus improving cleaning efficiency.

[0016] As an optional implementation, the ventilation slot includes a first ventilation slot and a second ventilation slot, both of which are multiple, and the multiple first ventilation slots and multiple second ventilation slots are arranged at a certain angle and staggered.

[0017] With this configuration, the air intake can draw in debris and other contaminants from the periphery of the device body through multiple first ventilation slots and multiple second ventilation slots, thus increasing the air intake range.

[0018] As an optional implementation, the first ventilation slot extends along the width direction of the device body, and the second ventilation slot extends along the cleaning direction of the cleaning device; wherein the width direction of the device body is perpendicular to the cleaning direction of the cleaning device.

[0019] With this configuration, the air intake can draw in debris and waste from different directions on the main body of the device through the first and second ventilation slots, thus improving cleaning efficiency.

[0020] As an optional implementation, the first ventilation slot penetrates the bottom shell, and the length of the first ventilation slot matches the width of the main body of the device; each first ventilation slot is connected to multiple second ventilation slots; the second ventilation slots are connected to the connecting slots.

[0021] With this configuration, the first ventilation slot can be connected to the connecting slot via the second ventilation slot, allowing airflow from all directions to enter the air intake through the roller brush chamber.

[0022] As an optional implementation, the penetration direction of the first ventilation slot and the connecting slot has an angle, which is greater than or equal to 90° and less than 180°.

[0023] With this configuration, the airflow direction can be adjusted and the airflow path optimized through the first ventilation slot.

[0024] As an optional implementation, the connecting part further includes a connecting hole, which is provided through the thickness direction of the base plate, and the connecting groove is provided overlapping the connecting hole; or, the connecting groove and the connecting hole are provided alternately.

[0025] This design, with both connecting slots and connecting holes, improves air suction efficiency.

[0026] As an optional implementation, the base plate also includes multiple support ribs, with each support rib having its two ends connected to the two side edges of the base plate respectively.

[0027] The support rib has at least one ventilation section. The inner wall of the ventilation section and the outer surface of the support rib have a height difference. When the air intake draws in air through the roller brush chamber, the airflow flowing through the outer surface of the support rib and the airflow flowing through the ventilation section have a velocity difference.

[0028] This design allows the airflow at the suction chamber to be disturbed through the ventilation section of the support ribs, reducing the chance of hair directly contacting the roller brush and preventing hair from getting tangled in the roller brush.

[0029] 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.

[0030] With this configuration, the frame and supporting ribs of the base plate form the skeleton structure of the base plate, which improves the structural strength of the cleaning device.

[0031] As an optional implementation, the connecting part includes a through groove, and the groove walls on both sides of the through groove are chamfered.

[0032] This design, with its chamfered edges, can disrupt airflow and prevent hair from getting tangled in the roller brush.

[0033] As an optional implementation, the connecting portion includes a through hole, and the supporting rib has at least one through hole, which is used to disturb the airflow at the suction port. This arrangement allows the airflow at the suction port to be disturbed through the connecting hole, preventing hair from becoming entangled.

[0035] This application provides a cleaning device and equipment. The cleaning device includes a main body, a roller brush, and a base plate. The main body has an air intake and a roller brush chamber, the roller brush chamber being connected to the air intake, and the roller brush being rotatably disposed within the roller brush chamber. The roller brush chamber is open towards the lower part of the main body, and the base plate covers the edge of the open portion of the roller brush chamber. The edge of the base plate has a connecting portion that connects the roller brush chamber and the outer space of the base plate. The cleaning device provided by this application guides airflow through the connecting portion, allowing hair, dust, and other debris to be quickly sucked in through the connecting portion, thereby improving cleaning efficiency.

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.

[0054] 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.

[0055] 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.

[0056] However, current cleaning equipment often leaves behind hair, dust, and other debris after cleaning, and its cleaning efficiency needs to be improved.

[0057] To address the aforementioned technical problems, this application provides a cleaning device and cleaning equipment. The cleaning device has a base plate at the open edge of the roller brush chamber, and the base plate has a connecting part. The connecting part connects the outer space of the cleaning device and the inner space of the roller brush chamber. When the air intake is drawing air, the connecting part can guide the airflow, allowing garbage and debris to be quickly sucked in through the connecting part, thereby improving cleaning efficiency.

[0058] The following section provides examples illustrating the application scenarios of the cleaning devices and equipment provided in the embodiments of this application.

[0059] The cleaning device provided in this application embodiment is applied in a cleaning equipment and is a cleaning structure in the cleaning equipment that comes into contact with the surface to be cleaned. The product type of the cleaning equipment in this application embodiment may include, but is 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 floor 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.

[0060] Figure 1 A schematic diagram of the bottom structure of a cleaning device with a communicating hole provided in an embodiment of this application; Figure 2 A schematic diagram of the bottom structure of a cleaning device with ventilation slots provided in an embodiment of this application; Figure 3 A schematic diagram of the bottom structure of a cleaning device with a second ventilation slot provided in an embodiment of this application; Figure 4 This is a schematic diagram of the structure of the bottom shell with ventilation slots provided in an embodiment of this application; Figure 5 A bottom view of the bottom shell with ventilation slots provided in an embodiment of this application; Figure 6 A schematic diagram of the structure of a base plate with a communicating groove provided in an embodiment of this application; Figure 7 A bottom view of a base plate with a communicating groove provided in an embodiment of this application; Figure 8 A bottom view of a base plate with a communicating hole provided in an embodiment of this application; Figure 9 This is a schematic diagram of the supporting ribs provided in an embodiment of this application.

[0061] Reference Figures 1 to 9 As shown, this application embodiment provides a cleaning device, including a device body 100, a roller brush 120, and a base plate 200; 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 120 is rotatably disposed in the roller brush cavity 110; the roller brush cavity 110 is openly disposed facing the lower part of the device body 100, and the base plate 200 is disposed on the edge of the open part of the roller brush cavity 110; the edge of the base plate 200 is provided with a connecting part, the connecting part connecting the outer space of the roller brush cavity 110 and the base plate 200.

[0062] Understandably, the roller brush 120 has a striking part protruding from the roller brush cavity 110. When the cleaning device is cleaning, the striking part of the roller brush 120 can strike the surface to be cleaned, making it easier to separate dust, hair and other debris from the surface to be cleaned. 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 device.

[0063] Understandably, the base plate 200 covering the open edge of the roller brush chamber 110 has a connecting portion. This connecting portion connects the outer space of the cleaning device and the inner space of the roller brush chamber 110. When the suction port draws air, air from the periphery of the device body 100 can enter the connecting portion, and pick up hair, dust, and other debris, which then enter the roller brush chamber 110 through the connecting portion and are finally drawn into the suction port. On the one hand, the connecting portion increases the ventilation area and improves suction efficiency; on the other hand, the cross-sectional area of ​​the connecting portion is much smaller than the opening area of ​​the roller brush chamber 110. When the suction port draws air, the airflow through the connecting portion is faster, and the hair, dust, and other debris picked up by the airflow can quickly enter the roller brush chamber 110 through the connecting portion, thereby improving cleaning efficiency.

[0064] Reference Figure 5 The direction of movement of the cleaning device during cleaning is defined as the Y direction, and the width direction of the device body 100 is defined as the X direction, which is perpendicular to the Y direction.

[0065] As one possible implementation, there are multiple connected parts, which are arranged at intervals along the circumferential edge of the base plate 200.

[0066] It should be noted that the base plate 200 has an opening in the middle, the area of ​​which matches or is smaller than the area of ​​the opening of the brush cavity 110. The frame 220 of the base plate 200 covers the open edge of the brush cavity 110. The connecting parts are arranged at intervals along the inner edge of the frame 220 of the base plate 200. The connecting parts can be provided on both sides of the base plate 200 in the width direction, or they can be omitted.

[0067] It should be noted that the width direction of the base plate 200 is the moving direction of the cleaning device during cleaning, i.e., the Y direction, and the length direction of the base plate 200 is the width direction of the main body 100 of the device, i.e., the X direction.

[0068] Reference Figure 1 and Figure 8 As one possible implementation, the connecting part includes a connecting hole 221, which is disposed through the thickness direction of the base plate 200, connecting the outer space of the base plate 200 and the inner space of the roller brush cavity 110. When the air intake is drawing air, part of the airflow can pass through the connecting hole 221, increasing the ventilation area and improving the air intake efficiency. The cross-section of the connecting hole 221 can be semi-circular and serrated along the inner edge of the base plate 200. The cross-section of the connecting hole 221 can also be circular, polygonal, or other shapes that facilitate airflow. This application embodiment does not make specific limitations.

[0069] It should be noted that the connecting hole 221 can be set on the inner edge of the frame 220 of the base plate 200, or on the outer edge of the frame 220 of the base plate 200, or on both the inner and outer edges of the frame 220 of the base plate 200.

[0070] In some embodiments, the bottom shell 300 may be provided with a connecting hole 221, which connects the brush cavity 110 and the lower space of the bottom shell 300.

[0071] Reference Figures 2 to 6 As one possible implementation, the connecting part includes a connecting groove 222, which is provided through the width of the bottom plate 200; a bottom shell 300 is provided under the device body 100, and the bottom shell 300 has a ventilation groove 310 on the side facing the surface to be cleaned, which connects the peripheral space of the cleaning device and the connecting groove 222.

[0072] For example, the connecting groove 222 is disposed on the side of the frame 220 of the base plate 200 near the ventilation groove 310 and is connected to the ventilation groove 310. The length of the connecting groove 222 is the same as the width of the frame 220. The width of the connection between the ventilation groove 310 and the connecting groove 222 can be the same as the width of the connecting groove 222. The ventilation groove 310 extends from the base plate 200 to the edge of the bottom shell 300, so that the connecting groove 222 is connected to the peripheral space of the cleaning device.

[0073] In some embodiments, each side of the frame 220 of the base plate 200 may be provided with a connecting groove 222, with only one side of the connecting groove 222 connecting to the ventilation hole.

[0074] As one possible implementation, the ventilation slot 310 includes a first ventilation slot 311 and a second ventilation slot 312. There are multiple first ventilation slots 311 and multiple second ventilation slots 312, and the multiple first ventilation slots 311 and multiple second ventilation slots 312 are arranged at a certain angle and staggered.

[0075] It should be noted that multiple first ventilation slots 311 are arranged at intervals along the Y direction, and multiple second ventilation slots 312 are arranged at intervals along the X direction. The first ventilation slots 311 and the second ventilation slots 312 can be arranged perpendicular to each other or not perpendicular to each other. The included angle between the first ventilation slots 311 and the second ventilation slots 312 is greater than 0° and less than or equal to 90°.

[0076] For example, the included angle between the first ventilation slot 311 and the second ventilation slot 312 can be 1°, 5°, 10°, 50°, 89°, 90°, etc., and the embodiments of this application do not make specific limitations.

[0077] As one possible implementation, the first ventilation slot 311 extends along the width direction of the device body 100, and the second ventilation slot 312 extends along the cleaning direction of the cleaning device; wherein the width direction of the device body 100 is perpendicular to the cleaning direction of the cleaning device.

[0078] It is understood that the first ventilation slot 311 extends along the X direction and the second ventilation slot 312 extends along the Y direction. The first ventilation slot 311 can connect the two sides of the device body 100 in the width direction, and the second ventilation slot 312 can connect the two sides of the device body 100 in the cleaning direction.

[0079] In some embodiments, the ventilation slot 310 may include only the second ventilation slot 312, such as Figure 3 .

[0080] As one possible implementation, the first ventilation slot 311 penetrates the bottom shell 300, and the length of the first ventilation slot 311 matches the width of the device body 100; each first ventilation slot 311 is connected to multiple second ventilation slots 312; the second ventilation slots 312 are connected to the connecting slot 222.

[0081] Understandably, when the air intake is activated, the roller brush chamber 110 generates negative pressure suction. On one hand, airflow enters the first ventilation slot 311 from both sides of the width of the main body 100 of the device, and flows from both ends of the first ventilation slot 311 towards the center. On the other hand, airflow enters from the end of the second ventilation slot 312 away from the connecting slot 222, and flows towards the connecting slot 222. During the process of the airflow from the first ventilation slot 311 flowing towards the center, it merges with the airflow from the second ventilation slot 312 and is carried to the connecting slot 222, from where it enters the roller brush chamber 110, and finally enters the air inlet. During the flow, the airflow can carry dust, hair, and other debris to the air intake and into the collection device inside the main body 100 of the device, achieving a cleaning effect.

[0082] The width of the first ventilation slot 311 can be the same as or different from the width of the second ventilation slot 312. For example, the width of the first ventilation slot 311 is twice that of the second ventilation slot 312. The airflow velocity of the first ventilation slot 311 is less than that of the second ventilation slot 312. When the airflow of the first ventilation slot 311 and the airflow of the second ventilation slot 312 converge, the first ventilation slot 311 is more likely to follow the airflow of the second ventilation slot 312 to the connecting slot 222.

[0083] As one possible implementation, the first ventilation slot 311 and the connecting slot 222 have an angle between their penetrating directions, and the angle between the first ventilation slot 311 and the connecting slot 222 is greater than or equal to 90° and less than 180°.

[0084] It is understandable that the through direction of the connecting groove 222 is the Y direction, and the angle between the first ventilation groove 311 and the Y direction is greater than or equal to 90° and less than 180°, such as... Figure 5 .

[0085] For example, the angle between the first ventilation slot 311 and the Y direction can be 90°, 100°, 120°, 150°, 179°, etc., and this application embodiment does not make specific limitations.

[0086] In some embodiments, the connecting portion further includes a connecting hole 221, which is disposed through the thickness direction of the base plate 200, and the connecting groove 222 is disposed overlapping the connecting hole 221; or, the connecting groove 222 and the connecting hole 221 are disposed alternately.

[0087] It is understood that in this embodiment, the base plate 200 is provided with a connecting hole 221 and the bottom shell 300 is provided with a ventilation groove 310. The ventilation groove 310 is connected to the roller brush cavity 110 through the connecting groove 222 on the base plate 200. The connecting groove 222 can overlap with the connecting hole 221, so that part of the airflow of the ventilation groove 310 can enter the roller brush cavity 110 from the connecting hole 221. The connecting groove 222 can also be staggered with the connecting hole 221. In this case, the airflow of the ventilation groove 310 directly enters the roller brush cavity 110 from the connecting groove 222.

[0088] Reference Figure 8 and Figure 9 , combined Figure 1 As an optional implementation, the base plate 200 also includes a plurality of support ribs 210, each of which is connected to the two side edges of the base plate 200 at both ends. The support rib 210 has at least one ventilation section, and the inner wall of the ventilation section has a height difference with the outer surface of the support rib 210. When the air intake is drawn into the air through the roller brush cavity 110, the airflow flowing through the outer surface of the support rib 210 has a velocity difference with the airflow flowing through the ventilation section.

[0089] Understandably, since the base plate 200 covers the roller brush cavity 110, when the air inlet draws air, the external air flows from the cavity opening of the roller brush cavity 110 to the air inlet and passes through the support ribs 210 on the base plate 200. Since the support ribs 210 are equipped with ventilation sections, there is a height difference between the inner wall of the ventilation section and the outer surface of the support ribs 210. When the airflow flows through the support ribs 210, the airflow flowing through the outer surface of the support ribs 210 and the airflow flowing through the ventilation section will generate a velocity difference, which will then cause turbulence. The multiple support ribs 210 disturb the airflow near the cavity opening of the roller brush cavity 110, suppressing the centripetal force generated by the rotation of the roller brush 120 from causing hair to wrap around the roller brush 120, reducing the probability of hair and fibers directly contacting the beating part of the roller brush 120. While preventing the roller brush 120 from wrapping hair, it can remove hair and fibers from the surface to be cleaned.

[0090] Each support rib 210 has one or more ventilation sections. For example, the number of connecting sections of each support rib 210 can be 1, 2, 3, 4, 5, etc., and this application embodiment does not make a specific limitation. Multiple ventilation sections can be arranged along the length direction of the support rib 210. While ensuring the support strength, multiple ventilation sections 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.

[0091] It should be noted that the frame 220 of the base plate 200 is arranged around the open edge of the roller brush cavity 110, and the two ends of the support rib 210 are respectively connected to the two sides of the frame 220. The two ends of the support rib 210 can be respectively connected to the two sides of the frame 220 in the width direction or to the two sides of the frame 220 in the length direction; wherein, the ventilation part is arranged through the support rib 210 in the width direction.

[0092] It should be noted that the width direction of the frame 220 is the direction of movement of the cleaning device during cleaning, i.e., the Y direction; the length direction of the frame 220 is the width direction of the device body 100, i.e., the X direction. When both ends of the support rib 210 are connected to the two sides of the frame 220 in the width direction, the width direction of the support rib 210 is the X direction and the length direction is the Y direction; when both ends of the support rib 210 are connected to the two sides of the frame 220 in the length direction, the width direction of the support rib 210 is the Y direction and the length direction is the X direction.

[0093] It should be noted that there are multiple support ribs 210. The multiple support ribs 210 can be arranged in parallel intervals along the brush cavity 110, or they can be arranged in non-parallel intervals, or the multiple support ribs 210 can be arranged in a cross pattern.

[0094] Understandably, multiple support ribs 210 can prevent the roller brush cavity 110 from deforming when the roller brush 120 is running at high speed or when the roller brush cavity 110 is under pressure. Multiple support ribs 210 can be arranged at equal intervals along the length of the roller brush cavity 110, and the support ribs 210 have an arc. The support ribs 210 protrude towards the surface to be cleaned. The arc setting of the support ribs 210 can further disturb the airflow at the cavity opening of the roller brush cavity 110 and prevent hair fibers from getting tangled.

[0095] It should be noted that the ventilation section can be either a through groove 211 or a through hole. Each support rib 210 has at least one through groove 211 or one through hole, and each support rib 210 can also have at least one through groove 211 and one through hole at the same time.

[0096] For example, the two ends of the support rib 210 are connected to the two sides of the frame 220 in the width direction, and the ventilation part is a through groove 211. Each support rib 210 has a through groove 211 in the middle of its length direction. When the air inlet draws air, part of the airflow flows through the through groove 211. By setting a specific angled structure in the through groove 211, that is, setting a specific angled chamfer 212, the chamfer 212 can induce turbulence. When the airflow passes through the chamfer 212, the geometric change leads to an increase in velocity gradient, breaks the laminar boundary layer and generates 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 120, thereby avoiding hair fibers from getting tangled in the roller brush 120.

[0097] This application also provides a cleaning device, which includes the aforementioned cleaning apparatus and a cleaning body, with the cleaning apparatus movably connected to the device body. When performing cleaning operations, the user can move the cleaning apparatus by pushing or pulling the device body.

[0098] It is understandable that a suction pipe can be connected between the cleaning device and the main body of the equipment, and a sewage tank can be installed on the main body of the equipment. Sewage sucked in by the cleaning device can enter the sewage tank through the suction pipe.

[0099] In addition, a fan unit can be installed on the main body of the equipment. The fan unit is used to generate negative pressure airflow, which in turn generates negative pressure suction at the air inlet. Since the air inlet and the roller brush chamber 110 are connected, and the opening of the roller brush chamber faces and is close to the surface to be cleaned, the debris and impurities on the surface to be cleaned facing the opening of the roller brush chamber can be sucked into the air inlet through the roller brush chamber 110. The clean airflow after being filtered by the wastewater tank is discharged to the outside of the main body of the equipment 200 after passing through the fan unit.

[0100] This application provides a cleaning device and equipment. The cleaning device includes a main body 100, a roller brush 120, and a base plate 200. The main body 100 has an air intake and a roller brush cavity 110, which is connected to the air intake. The roller brush 120 is rotatably disposed in the roller brush cavity 110. The roller brush cavity 110 is open towards the lower part of the main body 100, and the base plate 200 covers the edge of the open part of the roller brush cavity 110. The edge of the base plate 200 has a connecting portion that connects the roller brush cavity 110 and the outer space of the base plate 200. The cleaning device provided by this application guides the airflow through the connecting portion, allowing hair, dust, and other debris to be quickly sucked in through the connecting portion, thereby improving cleaning efficiency.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
