Technical Field
[0001] This utility model relates to the field of household appliance technology, specifically to cleaning equipment. Background Technology
[0002] Cleaning devices such as mite removers are small household appliances with functions such as mite removal, vacuuming, and sterilization. They can clean dust from furniture such as beds and sofas. The core working principle of mite removers is "beating, vacuuming, and sterilization." Mite removers include a roller brush with a beating function. In related technologies, the roller brush of mite removers uses a hard rubber strip roller brush for rolling and beating, which has the advantages of strong beating force and high frequency. However, the high-speed rotating hard rubber strip roller brush is very easy to get soft fabrics such as sheets and duvet covers into the roller brush cavity and get stuck in the roller brush, causing the beating and cleaning functions to fail and resulting in a poor user experience. Utility Model Content
[0003] In view of this, the present invention provides a cleaning device to solve the problem that the roller brush easily gets caught on bed sheets.
[0004] This utility model provides a cleaning device, including:
[0005] The bottom shell is provided with a first roller brush mounting cavity;
[0006] The first roller brush is rotatably disposed in the first roller brush mounting cavity;
[0007] A drive mechanism, located on the bottom shell, is capable of driving the first roller brush to rotate;
[0008] A roller brush cover is connected to the bottom shell, and the roller brush cover has a plurality of first openings spaced apart from the first roller brush mounting cavity.
[0009] Beneficial effects: The bottom shell is provided with a first roller brush mounting cavity; the first roller brush is rotatably mounted in the first roller brush mounting cavity. When the drive mechanism drives the first roller brush to rotate, the first roller brush contacts the surface to be cleaned to perform sweeping and patting. By providing multiple first openings at intervals corresponding to the first roller brush mounting cavity on the roller brush cover, the first roller brush will not extend out of the first openings. The intervals of the first openings can avoid the problem of bed sheets rolling up.
[0010] In one optional embodiment, the roller brush cover is connected to the bottom shell by a latch, the latch having a locked state and an unlocked state. When the latch is in the unlocked state, the roller brush cover is adapted to be separated from the bottom shell, and when the latch is in the locked state, the roller brush cover is connected to the bottom shell.
[0011] Beneficial effects: When the latch is in the unlocked state, the roller brush cover can be removed from the bottom shell. When the latch is in the locked state, the roller brush cover is connected to the bottom shell. The latch design facilitates the installation and removal of the roller brush cover.
[0012] In one optional embodiment, the bottom shell is further provided with a second roller brush mounting cavity, and the cleaning device further includes a second roller brush, which is rotatably disposed in the second roller brush mounting cavity. The driving mechanism is capable of driving the second roller brush to rotate. The second roller brush includes a roller brush shaft and a tapping block disposed on the roller brush shaft.
[0013] Beneficial effects: The drive mechanism drives the first and second roller brushes to rotate simultaneously. The first roller brush can clean up hair. By providing multiple first openings at intervals in the roller brush cover corresponding to the first roller brush mounting cavity, the first roller brush will not extend out of the first openings. The intervals between the first openings can prevent the problem of the sheets getting rolled up. The second roller brush includes a roller brush shaft and a beating block set on the roller brush shaft. The rotation of the beating block can remove dust mites. The beating force is strong. Therefore, this beating mechanism can achieve strong beating force without rolling up the sheets.
[0014] In one alternative embodiment, the first roller brush includes a brush roller and bristles disposed outside the brush roller.
[0015] Beneficial effect: Because the bristles are soft, they can prevent soft fabrics such as sheets and duvet covers from rolling up when the first roller rotates at high speed.
[0016] In one optional embodiment, the roller brush cover is provided with a plurality of second openings at intervals corresponding to the second roller brush mounting cavity, and the second openings are adapted for the tapping block to extend out.
[0017] Beneficial effects: The roller brush cover has multiple second openings at intervals corresponding to the second roller brush mounting cavity. The second openings are suitable for the extension of the beater block. The multiple second openings are spaced apart to avoid the problem of the sheet getting rolled up when the second roller brush rotates at high speed. In addition, dust mites shaken up by the beater block can enter the cleaning equipment through the second openings.
[0018] In one optional embodiment, the maximum height of the striking block extending beyond the bottom shell is H1, where 1mm ≤ H1 ≤ 6mm.
[0019] Beneficial effect: The maximum height of the patting block extending out of the bottom shell also refers to the interference between the patting block and the surface to be cleaned. 1mm≤H1≤6mm can ensure the patting effect.
[0020] In one alternative embodiment, the width of the second opening is smaller than the width of the first opening, and the width of the second opening is L1, where 5mm ≤ L1 ≤ 20mm.
[0021] Beneficial effect: Because the width of the first opening is greater than the width of the second opening, the larger width of the first opening allows the bristles of the first roller brush to make large-area contact with the surface to be cleaned through the first opening.
[0022] In one optional embodiment, the second opening is provided in a one-to-one correspondence with the striking block, and the gap between the edge of the second opening and the striking block is L2, where 0.5mm≤L2≤5mm.
[0023] Beneficial effects: The gap between the edge of the second opening and the beating block is 0.5mm to 5mm, which ensures that dust mites can enter the cleaning device through the second opening, while avoiding the problem of sheets getting rolled up when the second roller brush rotates at high speed.
[0024] In one alternative embodiment, an airflow passage is provided between the first opening and the second opening.
[0025] Beneficial effects: By setting an airflow channel between the first and second openings, it is possible to ensure that the dust mites agitated by the beating blocks are drawn into the air duct of the roller brush chamber, thereby improving the dust and mite removal effect.
[0026] In one optional embodiment, the plane where the airflow channel is located is higher than the bottom plane of the bottom shell, and in the vertical direction, the distance between the plane where the airflow channel is located and the bottom plane of the bottom shell is H2, where 1mm≤H2≤3mm.
[0027] Beneficial effects: The plane where the airflow channel is located is higher than the bottom plane of the bottom shell, which can suck the dust mites that are knocked up by the beating block into the first roller brush installation cavity, and then into the air duct of the roller brush cavity, thus improving the dust and mite removal effect.
[0028] In one alternative embodiment, the patting block has a non-circular cross-section perpendicular to the roller brush axis.
[0029] Beneficial effects: Because the cross-section of the beating block perpendicular to the roller brush axis is not circular, the beating block intermittently contacts the surface to be cleaned while rotating, and the beating force is strong, which can effectively knock out dust mites.
[0030] In one alternative implementation, two adjacent sides of the striking block are connected by an arc surface.
[0031] Beneficial effect: The two adjacent sides of the patting block are connected by a rounded surface, which can protect the surface to be cleaned while ensuring the patting force. Attached Figure Description

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0054] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0055] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0056] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0057] Cleaning devices such as mite removers are small household appliances with functions such as mite removal, vacuuming, and sterilization. They can clean dust from furniture such as beds and sofas. The core working principle of mite removers is "beating, vacuuming, and sterilization." Mite removers include a roller brush with a beating function. In related technologies, the roller brush of mite removers uses a hard rubber strip roller brush for rolling and beating, which has the advantages of strong beating force and high frequency. However, the high-speed rotating hard rubber strip roller brush is very easy to get soft fabrics such as sheets and duvet covers into the roller brush cavity and get stuck in the roller brush, causing the beating and cleaning functions to fail and resulting in a poor user experience.
[0058] The related technology discloses a mite removal device, including: an air intake duct, a drive unit, and at least two beaters; the at least two beaters are spaced apart at the inlet end of the air intake duct; the drive unit is provided with at least two drive ends, each drive end being connected to one beater to drive the beaters. By driving multiple beaters to agitate them, the multiple beaters beat up dust mites, dust, dander, hair, and other particles, improving beating efficiency. The air intake duct is used for dust extraction and mite removal, significantly increasing the beating intensity and thus improving mite removal efficiency.
[0059] The beater in the aforementioned related technologies is a roller brush. If the rotation speed of the roller brush is increased, soft fabrics such as bed sheets and duvet covers are easily rolled into the roller brush cavity and jammed. If the rotation speed is low, the beating efficiency is low.
[0060] The following is combined Figures 1 to 18 The following describes embodiments of the present invention.
[0061] According to an embodiment of the present invention, a cleaning device is provided, comprising: a base shell 4, a first roller brush 1, a drive mechanism 3, and a roller brush cover 5.
[0062] The bottom shell 4 is provided with a first roller brush mounting cavity 401; the first roller brush 1 is rotatably mounted in the first roller brush mounting cavity 401; the drive mechanism 3 is provided in the bottom shell 4 and can drive the first roller brush 1 to rotate; the roller brush cover 5 is connected to the bottom shell 4, and the roller brush cover 5 is provided with a plurality of first openings 501 at intervals corresponding to the first roller brush mounting cavity 401.
[0063] In this embodiment, the bottom shell 4 is provided with a first roller brush mounting cavity 401; the first roller brush 1 is rotatably disposed in the first roller brush mounting cavity 401. When the driving mechanism 3 drives the first roller brush 1 to rotate, the first roller brush 1 contacts the surface to be cleaned to perform cleaning and patting. By providing multiple first openings 501 at intervals corresponding to the first roller brush mounting cavity 401 on the roller brush cover 5, the first roller brush 1 will not extend out of the first openings 501. The first openings 501 are arranged at intervals to avoid the problem of bed sheets rolling up.
[0064] Specifically in one embodiment, such as Figure 16 As shown, the bottom of the first roller brush mounting cavity 401 is provided with a plurality of dividing ribs 502, which divide the bottom opening of the first roller brush mounting cavity 401 into a plurality of first openings 501.
[0065] In one specific embodiment, the roller brush cover 5 is detachably connected to the bottom shell 4, making it easy to remove the roller brush cover 5 to clean the first roller brush 1.
[0066] In one embodiment, the roller brush cover 5 is connected to the bottom shell 4 by a latch 6, which has a locked state and an unlocked state. When the latch 6 is in the unlocked state, the roller brush cover 5 is adapted to be separated from the bottom shell 4. When the latch 6 is in the locked state, the roller brush cover 5 is connected to the bottom shell 4.
[0067] In this embodiment, when the latch 6 is in the unlocked state, the roller brush cover 5 can be removed from the bottom shell 4. When the latch 6 is in the locked state, the roller brush cover 5 is connected to the bottom shell 4. The latch 6 facilitates the installation and removal of the roller brush cover 5.
[0068] Specifically, such as Figure 17 As shown, Figure 17 There are two latches 6 in the middle, one of which is locked and the other is unlocked.
[0069] In one embodiment, the bottom shell 4 is further provided with a second roller brush mounting cavity 402, and the cleaning device also includes a second roller brush 2. The second roller brush 2 is rotatably disposed in the second roller brush mounting cavity 402, and the driving mechanism 3 can drive the second roller brush 2 to rotate. The second roller brush 2 includes a roller brush shaft 201 and a tapping block 202 disposed on the roller brush shaft 201.
[0070] In this embodiment, the drive mechanism 3 drives the first roller brush 1 and the second roller brush 2 to rotate simultaneously. The first roller brush 1 can clean hair. By providing multiple first openings 501 at intervals in the roller brush cover 5 corresponding to the first roller brush mounting cavity 401, the first roller brush 1 will not extend out of the first openings 501. The intervals of the first openings 501 can avoid the problem of the sheets getting rolled up. The second roller brush 2 includes a roller brush shaft 201 and a beating block 202 disposed on the roller brush shaft 201. The rotation of the beating block 202 can remove dust mites. The beating force is strong. Therefore, this beating mechanism can achieve strong beating force without rolling up the sheets.
[0071] In one specific embodiment, the bottom shell 4 is provided with a brush cavity air duct 403, and the first brush mounting cavity 401 and the second brush mounting cavity 402 are both connected to the brush cavity air duct 403.
[0072] In one embodiment, the first roller brush 1 includes a brush roller 101 and bristle strips 102 disposed outside the brush roller 101.
[0073] In this embodiment, since the brush 102 is relatively soft, it can prevent soft fabrics such as sheets and duvet covers from rolling up when the first roller brush 1 rotates at high speed.
[0074] In one embodiment, the number of bristle strips 102 is 3-6, and the bristle strips 102 are arranged in a straight line or spiral along the length extension direction of the brush roller 101.
[0075] In this embodiment, the number of bristle strips 102 is 3-6. The bristle strips 102 are arranged in a straight line or spiral along the length extension direction of the brush roller 101, which can ensure that the bristle strips 102 can contact the surface to be cleaned, thereby ensuring the patting effect.
[0076] Specifically in one embodiment, such as Figure 6 As shown, there are 4 bristle strips 102, which are arranged in a straight line along the length extension direction of the brush roller 101.
[0077] In one specific embodiment, the cleaning device includes a roller brush cavity air duct 403, which is connected to a first roller brush mounting cavity 401 and a second roller brush mounting cavity 402. The first roller brush 1 can sweep up hair, and the second roller brush 2 can beat up dust mites. The hair and dust mites are sucked into the roller brush cavity air duct 403.
[0078] It should be noted that the bristles 102 of the first roller brush 1 will not extend out of the first opening 501. However, during the use of the cleaning equipment, soft items such as sheets and duvet covers will float up and extend into the first opening 501 to achieve an interference patting effect. However, since multiple first openings 501 are set at intervals, the problem of sheets rolling up will not occur.
[0079] In one embodiment, the roller brush cover 5 is provided with a plurality of second openings 503 at intervals corresponding to the second roller brush mounting cavity 402, and the second openings 503 are adapted to extend the patting block 202.
[0080] In this embodiment, the roller brush cover 5 is provided with a plurality of second openings 503 at intervals corresponding to the second roller brush mounting cavity 402. The second openings 503 are adapted to extend the slapping block 202. The multiple second openings 503 are arranged at intervals to avoid the problem of the bed sheet rolling when the second roller brush 2 rotates at high speed. In addition, the dust mites slapped up by the slapping block 202 can enter the cleaning equipment through the second openings 503.
[0081] In one embodiment, the maximum height of the striking block 202 extending out of the bottom shell 4 is H1, where 1mm ≤ H1 ≤ 6mm.
[0082] In this embodiment, the maximum height of the tapping block 202 extending out of the bottom shell 4 also refers to the interference between the tapping block 202 and the surface to be cleaned, which is 1mm≤H1≤6mm, to ensure the tapping effect.
[0083] In a preferred embodiment, H1 is 3mm, which can better balance the striking force and noise.
[0084] In one embodiment, the width of the second opening 503 is less than the width of the first opening 501, and the width of the second opening 503 is L1, where 5mm ≤ L1 ≤ 20mm.
[0085] In this embodiment, since the width of the first opening 501 is greater than the width of the second opening 503, the larger width of the first opening 501 allows the bristles 102 of the first roller brush 1 to make large-area contact with the surface to be cleaned through the first opening 501.
[0086] In a preferred embodiment, the width of the second opening 503 is 12 mm.
[0087] In one embodiment, the second opening 503 is provided in a one-to-one correspondence with the striking block 202, and the gap between the edge of the second opening 503 and the striking block 202 is L2, 0.5mm≤L2≤5mm.
[0088] In this embodiment, the gap between the edge of the second opening 503 and the tapping block 202 is 0.5mm to 5mm, which ensures that dust mites can enter the cleaning device through the second opening 503, while avoiding the problem of the bed sheet getting rolled up when the second roller brush 2 rotates at high speed.
[0089] In a preferred embodiment, the gap between the edge of the second opening 503 and the striking block 202 is 1 mm.
[0090] In one embodiment, an airflow channel 504 is provided between the first opening 501 and the second opening 503.
[0091] In this embodiment, by providing an airflow channel 504 between the first opening 501 and the second opening 503, it can be ensured that the dust mites agitated by the beating block 202 are sucked into the air duct 403 of the roller brush cavity, thereby improving the dust and mite removal effect.
[0092] In one specific embodiment, the bottom of the first roller brush mounting cavity 401 is provided with a plurality of dividing ribs 502. The dividing ribs 502 divide the bottom opening of the first roller brush mounting cavity 401 into a plurality of first openings 501. The dividing ribs 502 extend from the bottom surface of the roller brush cover 5 to the second opening 503. The area between two connected dividing ribs 502 forms an airflow channel 504.
[0093] In one embodiment, the plane where the airflow channel 504 is located is higher than the bottom plane of the bottom shell 4, and in the vertical direction, the distance between the plane where the airflow channel 504 is located and the bottom plane of the bottom shell 4 is H2, 1mm≤H2≤3mm.
[0094] In this embodiment, the plane of the airflow channel 504 is higher than the bottom plane of the bottom shell 4, which can suck the dust mites agitated by the beating block 202 into the first roller brush mounting cavity 401, and then into the roller brush cavity air duct 403, thereby improving the dust and mite removal effect.
[0095] In a preferred embodiment, the distance between the plane of the airflow channel 504 and the bottom plane of the bottom shell 4 is 2 mm.
[0096] In one embodiment, the patting block 202 has a non-circular cross-section perpendicular to the brush shaft 201.
[0097] In this embodiment, since the cross section of the tapping block 202 perpendicular to the roller brush shaft 201 is non-circular, the tapping block 202 intermittently contacts the surface to be cleaned and taps it when it rotates. The tapping force is strong and can effectively knock out dust mites.
[0098] In one specific embodiment, the beating block 202 is generally triangular in shape, and the cross section of the beating block 202 perpendicular to the roller brush shaft 201 is triangular. Therefore, it can be ensured that the beating block 202 intermittently contacts the surface to be cleaned and beats it when rotating, with strong beating force, which can effectively knock out dust mites.
[0099] In one embodiment not shown in the figure, the tapping block 202 may be a cam.
[0100] In another embodiment not shown in the figure, the striking block 202 can be a square prism, a pentagonal prism, etc.
[0101] In one embodiment, such as Figure 11 and Figure 12As shown, the two adjacent sides 2021 of the striking block 202 are connected by an arc surface 2022.
[0102] In this embodiment, the two adjacent sides 2021 of the patting block 202 are connected by an arc surface 2022, which can protect the surface to be cleaned while ensuring the patting force.
[0103] In the specific processing, a triangular prism-shaped striking block 202 can be processed first, and then the sharp corners between two adjacent side surfaces 2021 can be rounded to form an arc surface 2022.
[0104] In one embodiment, multiple tapping blocks 202 are arranged at intervals along the axial direction of the brush shaft 201.
[0105] In this embodiment, multiple beating blocks 202 are spaced apart along the axial direction of the roller brush shaft 201, which can further enhance the beating force and effectively knock out dust mites.
[0106] In one embodiment, such as Figure 11 and Figure 12 As shown, multiple striking blocks 202 are arranged in a straight line or a spiral.
[0107] In this embodiment, when multiple tapping blocks 202 are arranged in a spiral, it can be ensured that at any time the roller brush shaft 201 rotates, there is a tapping block 202 that can contact the surface to be cleaned, thus ensuring the tapping effect.
[0108] In this embodiment, multiple striking blocks 202 are preferably arranged in a spiral.
[0109] In one embodiment, the drive mechanism 3 includes a drive motor 301, a first roller brush drive rod 302, a second roller brush drive rod 303, a first transmission belt 304, and a second transmission belt 305. The first roller brush drive rod 302 is connected to the brush roller 101; the second roller brush drive rod 303 is connected to the roller brush shaft 201; the first transmission belt 304 drives the output shaft of the drive motor 301 and the second roller brush drive rod 303; and the second transmission belt 305 drives the second roller brush drive rod 303 and the first roller brush drive rod 302.
[0110] In this embodiment, when the drive motor 301 is working, it drives the second roller brush drive rod 303 to rotate via the first transmission belt 304. The second roller brush drive rod 303 drives the second roller brush 2 to rotate synchronously. The second transmission belt 305 connects the second roller brush drive rod 303 and the first roller brush drive rod 302. Therefore, the second transmission belt 305 drives the first roller brush drive rod 302 to rotate, and the first roller brush drive rod 302 drives the first roller brush 1 to rotate synchronously. Thus, it is possible to drive the first roller brush 1 and the second roller brush 2 to rotate simultaneously through a single drive mechanism 3.
[0111] In one embodiment, such as Figure 6 and Figure 10 The output shaft of the drive motor 301 is provided with a first meshing tooth 3011, the second roller brush drive rod 303 is provided with a spline 3031, the first roller brush drive rod 302 is provided with a drive gear 3021, the first meshing tooth 3011 and the spline 3031 mesh with the first transmission belt 304, and the spline 3031 and the drive gear 3021 mesh with the second transmission belt 305.
[0112] In this embodiment, the output shaft of the drive motor 301 is provided with a first meshing tooth 3011, and the second roller brush drive rod 303 is provided with a spline 3031. The first meshing tooth 3011 and the spline 3031 mesh with the first transmission belt 304, which can ensure that the first transmission belt 304 smoothly drives the second roller brush drive rod 303 to rotate. The first roller brush drive rod 302 is provided with a drive gear 3021, and the spline 3031 and the drive gear 3021 mesh with the second transmission belt 305, which can ensure that the second transmission belt 305 smoothly drives the first roller brush drive rod 302 to rotate.
[0113] In one specific embodiment, the first meshing tooth 3011 and the spline 3031 have the same number of teeth and the same tip circle radius. Therefore, the output shaft speed of the drive motor 301 is the same as the speed of the second roller brush drive rod 303, which can ensure that the second roller brush 2 rotates at high speed and improves the patting efficiency. The number of teeth of the spline 3031 is less than the number of teeth of the drive gear 3021, and the tip circle radius of the drive gear 3021 is greater than the tip circle radius of the spline 3031. The second transmission belt 305 can reduce the speed of the first roller brush 1 to avoid the bed sheet from rolling due to the excessive speed of the first roller brush 1.
[0114] In one specific embodiment, the second roller brush drive rod 303 and the roller brush shaft 201 are inserted together, which can improve assembly efficiency.
[0115] In one specific embodiment, the end of the second roller brush drive rod 303 is quadrilateral, and the roller brush shaft 201 is provided with a quadrilateral hole. The end of the second roller brush drive rod 303 is inserted into the quadrilateral hole, which can improve assembly efficiency and ensure that the second roller brush 2 can be driven to rotate synchronously by the second roller brush 303.
[0116] In one specific embodiment, the first roller brush drive rod 302 and the brush roller 101 are inserted together, which can improve assembly efficiency.
[0117] Specifically in one embodiment, such as Figure 9As shown, the first roller brush drive rod 302 includes polygonal rod segments, including a first polygonal rod segment 3022 and a second polygonal rod segment 3023. The first polygonal rod segment 3022 is close to the drive gear 3021. From the end adjacent to the first polygonal rod segment 3022 to the end away from the first polygonal rod segment 3022, the cross-sectional area of the second polygonal rod segment 3023 gradually decreases. Correspondingly, as shown... Figure 6 As shown, the brush roller 101 is provided with a polygonal hole 1011. The shape of the polygonal hole 1011 is consistent with the shape of the polygonal rod segment, and the setting of the second polygonal rod segment 3023 can guide the polygonal rod segment to be inserted into the polygonal hole 1011.
[0118] In one embodiment, the drive mechanism 3 further includes a bracket 306, and the drive motor 301, the first roller brush drive rod 302, and the second roller brush drive rod 303 are all mounted on the bracket 306.
[0119] In this embodiment, by setting the bracket 306, the drive motor 301, the first roller brush drive rod 302, and the second roller brush drive rod 303 are all set on the bracket 306. Therefore, the drive mechanism 3 can be assembled into an integral component, and then the integral component can be installed into the bottom shell 4 of the cleaning equipment, which makes installation easier.
[0120] In one specific embodiment, the bracket 306 is provided with a first through hole 3061, a second through hole 3062, and a third through hole 3063. The first through hole 3061 is used for the output shaft of the drive motor 301 to pass through, the second through hole 3062 is used for the first roller brush drive rod 302 to pass through, and the third through hole 3063 is used for the second roller brush drive rod 303 to pass through. The output shaft of the drive motor 301 is rotatably disposed in the first through hole 3061, the first roller brush drive rod 302 is rotatably disposed in the second through hole 3062, and the second roller brush drive rod 303 is rotatably disposed in the third through hole 3063.
[0121] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
