[0060] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0061] In this embodiment of the application, the first direction is the direction corresponding to the X-axis, the second direction is the direction corresponding to the Z-axis, and the third direction is the direction corresponding to the Y-axis, as an example for explanation.

[0062] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of the cleaning equipment 1000 provided by this utility model.

[0063] like Figure 1 As shown, the cleaning device 1000 includes a brush head assembly 100, a first liquid storage tank 200, a separation tank 300, a second liquid storage tank 400, and a main unit 500. The brush head assembly 100 can be connected to at least one of the first liquid storage tank 200, the separation tank 300, and the second liquid storage tank 400, and is also connected to the main unit 500. It can be used to perform cleaning operations on the target object, including at least one of brushing, scraping, and wastewater recovery. The first liquid storage tank 200 is used to supply cleaning water to the brush head assembly 100. The separation tank 300 is connected to the brush head assembly 100 and the main unit 500, and is used to separate wastewater, dust, and other impurities generated during the cleaning process of the brush head assembly 100 on the target object. The separated wastewater can be stored in the second liquid storage tank 400, and the separated dust can be stored in the dust recovery component of the separation tank 300, such as on a filter screen or filter element structure installed inside the separation tank 300. The main unit 500 provides power for the brush head device 100 to perform cleaning operations and for the separation chamber 300 to perform separation operations.

[0064] The first liquid storage tank 200 can be connected to at least one of the separation tank 300, the brush head device 100 and the main unit 500; the second liquid storage tank 400 can be connected to at least one of the separation tank 300, the first liquid storage tank 200, the brush head device 100 and the main unit 500; and the main unit 500 is connected to at least one of the first liquid storage tank 200, the separation tank 300 and the second liquid storage tank 400.

[0065] For example, the first liquid storage tank 200, the separation tank 300, and the second liquid storage tank 400 are stacked vertically and connected to the main unit 500, respectively, and the brush head device 100 is connected to the separation tank 300. When the main unit 500 is started, the first liquid storage tank 200 sprays cleaning water onto the target to be cleaned through the brush head device 100. The brush head device 100 performs a brushing and scraping action while collecting the generated wastewater. The wastewater is separated by the separation tank 300 and then stored in the second liquid storage tank 400.

[0066] It is understood that the first liquid storage tank 200 and the second liquid storage tank 400 can be set on the same floor as the separation tank 300, and no restrictions are imposed here.

[0067] In some embodiments, the main unit 500 may include a gripping housing and a negative pressure device. The gripping housing may form a gripping part and an air outlet part. The air outlet part may be used to house the negative pressure device, which generates a suction airflow when it is working. This suction airflow creates negative pressure within the cleaning device 1000, thereby achieving the function of suction cleaning. The negative pressure device may be a fan.

[0068] In some embodiments, the main unit 500 may further include a power supply device and an electronic control device. The power supply device may include a power source, and the electronic control device may include a display screen, buttons, triggers, switches, or a touchscreen. The negative pressure device, electronic control device, and power supply device may be electrically connected to the brush head assembly 100 and the separation chamber 300.

[0069] In some embodiments, a water pump device may be disposed within the grip portion for pumping cleaning water from the first liquid reservoir 200 to the brush head device 100.

[0070] In some embodiments, the cleaning device 1000 further includes a third liquid reservoir for storing cleaning agent, and the pump device further includes a peristaltic pump, which may be disposed in the air outlet for pumping the cleaning agent in the third liquid reservoir to the brush head device 100.

[0071] Please see Figure 2 , Figure 2 This is a three-dimensional structural diagram of the brush head device 100 provided by this utility model.

[0072] like Figure 2As shown, in some embodiments, the brush head device 100 includes a scraper 20, a brush head 30, and a brush head connecting seat 50. The scraper 20 includes a plurality of suction ports 211 and is slidably connected to the brush head 30 for performing a scraping action on the target to be cleaned and for collecting wastewater. The brush head 30 includes a brush head component 31 and a drive device 10, and the brush head 30 is slidably connected to the brush head connecting seat 50 and connected to the main unit 500 of the cleaning device 1000 through the brush head connecting seat 50. The drive device 10 is connected to the brush head component 31 and is used to drive the brush head component 31 to perform a brushing action on the target to be cleaned. Under the action of external force, the scraper 20 can be relatively displaced relative to the brush head 30 in a third direction.

[0073] The first liquid storage chamber 200, the separation chamber 300, and the second liquid storage chamber 400 are connected to the brush head 30 and / or the scraper 20.

[0074] It is understandable that the brush head connector 50 can be detachably connected to the separation chamber 300 through structural engagement, threaded connection, or other means, or it can be integrally formed with the shell of the separation chamber 300; no limitation is made here.

[0075] Please see Figure 3 ,like Figure 3 As shown, in some embodiments, the brush head 30 includes a cleaning brush 31 and a drive device 10. The brush head 30 is adapted to connect with the host 500 of the cleaning device 1000. The drive device 10 is connected to the cleaning brush 31 and is used to drive the cleaning brush 31 to perform a brushing action on the target to be cleaned.

[0076] Please see Figures 4 to 6 The cleaning brush 31 is adapted to connect with the drive unit 10 of the cleaning device 1000. The cleaning brush 31 includes a brush body component 32 and a bristle component 33.

[0077] The brush body component 32 is provided with a connecting structure 34 and a bristle mounting part 35, and the brush body component 32 is detachably connected to the drive device 10 through the connecting structure 34.

[0078] The bristle component 33 includes at least a first bristle group 331, a second bristle group 332 and a third bristle group 333 disposed on the bristle mounting portion 35. The first bristle group 331, the second bristle group 332 and the third bristle group 333 are arranged along a first direction and stacked along a second direction different from the first direction.

[0079] The first bristle group 331, the second bristle group 332 and the third bristle group 333 each include multiple bristle tufts, and at least two of the bristle groups in the first bristle group 331, the second bristle group 332 and the third bristle group 333 have some bristle tufts that extend in different directions.

[0080] For example, some bristle tufts of the first bristle group 331 extend along a first preset direction, and some bristle tufts of the second bristle group 332 extend along a second preset direction. Optionally, some bristle tufts of the third bristle group 333 may extend along the first preset direction, or some bristle tufts of the third bristle group 333 may extend along the second preset direction, or some bristle tufts of the third bristle group 333 may extend along a third preset direction.

[0081] In this embodiment, at least two of the bristle groups 331, 332 and 333 have different bristle tufts extending in different directions. That is, at least two of the bristle groups have some bristle tufts staggered. With this arrangement, the bristle tufts can more comprehensively cover all corners and crevices of the surface to be cleaned, and can also better adapt to different cleaning surfaces, thereby effectively improving the cleaning effect.

[0082] like Figure 4 and Figure 5 As shown, in some embodiments, the drive device 10 is provided with a first adapter position 36 and a second adapter position 37, the first adapter position 36 being used to connect at least one cleaning brush 31, and the second adapter position 37 being used to connect at least one cleaning brush 31.

[0083] The connection structures 34 corresponding to the cleaning brush 31 connected to the first adapter 36 and the cleaning brush 31 connected to the second adapter 37 are different.

[0084] In this embodiment, the cleaning brush 31 is connected to the drive device 10 through different adapter positions and connection structures 34, so that each cleaning brush 31 can be disassembled, cleaned and replaced individually.

[0085] In some embodiments, the cleaning brush 31 connected to the first adapter 36 has a first magnetic element 38, and the cleaning brush 31 connected to the second adapter 37 has a second magnetic element 39.

[0086] The cleaning brush 31 connected to the first adapter position 36 is magnetically adsorbed and adapted to the first adapter position 36 of the driving device 10 through the first magnetic element 38, and the cleaning brush 31 connected to the second adapter position 37 is magnetically adsorbed and adapted to the second adapter position 37 of the driving device 10 through the second magnetic element 39, and the first magnetic element 38 and the second magnetic element 39 have different magnetisms.

[0087] To better understand, illustrative, such as Figure 4 As shown, the first cleaning brush 31a connected to the first adapter 36 has a first magnetic element 38, and the second cleaning brush 31b connected to the second adapter 37 has a second magnetic element 39. It can be understood that the only difference between the first cleaning brush 31a and the second cleaning brush 31b is the magnetic element.

[0088] In this embodiment, the first magnetic component 38 and the second magnetic component 39 are magnetically adsorbed and assembled with the first adapter position 36 and the second adapter position 37 of the driving device 10, respectively. The installation method is simple and detachable, which facilitates the replacement of the consumable cleaning brush 31. Furthermore, the different magnetism of the first magnetic component 38 and the second magnetic component 39 facilitates the guiding effect when installing the cleaning brush 31.

[0089] In some embodiments, the connection structure 34 further includes a snap-fit ​​assembly 40, through which the cleaning brush 31 is snapped into contact with the drive device 10, further fixing the cleaning brush 31, preventing the cleaning brush 31 from loosening or falling off, and ensuring the stability of the connection between the cleaning brush 31 and the drive device 10.

[0090] In some embodiments, the first bristle group 331 includes a plurality of first bristle tufts 3311, the second bristle group 332 includes a plurality of second bristle tufts 3321, and the third bristle group 333 includes a plurality of third bristle tufts 3331.

[0091] In this configuration, at least a portion of the first bristle tufts 3311 extend along a first preset direction, with a first angle between the first preset direction and a third preset direction; and at least a portion of the third bristle tufts 3331 extend along a second preset direction, or at least a portion of the second bristle tufts 3321 extend along a second preset direction, with a second angle between the second preset direction and a third preset direction.

[0092] In this embodiment, the first bristle tuft 3311 may contain all or part of bristles extending along a first preset direction, with a first angle between the first preset direction and a third preset direction. The third bristle tuft 3331 may contain all or part of bristles extending along a second preset direction, with a second angle between the second preset direction and the third preset direction. Optionally, the second bristle tuft 3321 may contain all or part of bristles extending along a second preset direction. That is, by adjusting the direction and angle of the first bristle tuft 3311, the second bristle tuft 3321, and the third bristle tuft 3331, the brush can better adapt to different cleaning needs.

[0093] In some implementations, the first included angle is 0-20 degrees, and the second included angle is 0-20 degrees.

[0094] In this embodiment, the first included angle between the first preset direction and the third third direction is 0-20 degrees, and the second included angle between the second preset direction and the third third direction is 0-20 degrees. With this setting, the bristle tufts of the first bristle group 331 and the third bristle group 333 can form a fan-shaped cleaning surface, resulting in better cleaning effect.

[0095] In some embodiments, the included angle between any two adjacent first bristle tufts 3311 and a third direction is different.

[0096] Optionally, the angle formed between any two adjacent second bristle tufts 3321 and a third direction may be different.

[0097] Optionally, the angle formed between any two adjacent third bristle tufts 3331 and the third direction may be different.

[0098] In this embodiment, any two adjacent bristle clusters in the first bristle group 331, the second bristle group 332, and the third bristle group 333 are arranged with different angles to a third direction. This arrangement facilitates deeper contact of the bristle clusters with recessed or hard-to-reach areas of the target surface to be cleaned, thereby improving the cleaning effect.

[0099] In some embodiments, the first difference between the angle formed between any two adjacent first bristle clusters 3311 and a third direction is 1-5 degrees.

[0100] Optionally, the second difference between the angles formed between any two adjacent third bristle clusters 3331 and the third direction is 1-5 degrees.

[0101] Indicative, such as Figure 6 As shown, the angle between the bristle tuft A at the first position in the first bristle group 331 and the third direction is α, and the angle between the bristle tuft B at the second position in the first bristle group 331 and the third direction is β. The difference between the angles α and β is 1-5 degrees.

[0102] In this embodiment, the angle difference between any two adjacent bristle clusters in the first bristle group 331 and the third bristle group 333 and the third direction is 1-5 degrees, which can enhance the overall stability of the bristles and make the bristles less prone to deformation when encountering greater resistance during the cleaning process.

[0103] In some embodiments, a second bristle group 332 is disposed between a first bristle group 331 and a third bristle group 333, the first difference and the second difference are the same, and a plurality of second bristle clusters 3321 extend in a third direction.

[0104] In this embodiment, the second bristle group 332 is disposed between the first bristle group 331 and the third bristle group 333, and the second bristle cluster 3321 extends along a third direction. The bristle clusters of the first bristle group 331 and the third bristle group 333 all extend in the same preset direction, and the angle difference between any two adjacent bristle clusters in the first bristle group 331 and the third bristle group 333 and the third direction is the same. This arrangement can disperse the force direction of the bristle clusters at different angles, making the wear of each bristle cluster more uniform and preventing some bristle clusters from being excessively worn due to long-term force in the same direction. It also provides a multi-angle cleaning effect. In some specific embodiments, when the angle difference between any two adjacent bristle clusters in the first bristle group 331 and the third bristle group 333 and the third direction is 2 degrees, the cleaning effect and overall stability of the bristles are better.

[0105] In some embodiments, the second bristle group 332 is disposed between the first bristle group 331 and the third bristle group 333, and all the first bristle clusters 3311 of the first bristle group 331 extend along a first preset direction, all the third bristle clusters 3331 of the third bristle group 333 extend along a second preset direction, and all the second bristle clusters 3321 of the second bristle group 332 extend along a third preset direction.

[0106] Alternatively, the second bristle group 332 is disposed between the first bristle group 331 and the third bristle group 333, and all the first bristle clusters 3311 of the first bristle group 331 and all the third bristle clusters 3331 of the third bristle group 333 extend along a first preset direction, and all the second bristle clusters 3321 of the second bristle group 332 extend along a second preset direction.

[0107] Alternatively, the second bristle group 332 is disposed between the first bristle group 331 and the third bristle group 333. In this configuration, some of the first bristle tufts 3311 extend along a first preset direction, and some of the first bristle tufts 3311 extend along a second preset direction; some of the third bristle tufts 3331 extend along the first preset direction, and some of the third bristle tufts 3331 extend along the second preset direction; and all the second bristle tufts 3321 of the second bristle group 332 extend along the second preset direction.

[0108] To better understand, Figures 7a to 7c Some specific embodiments covered in this implementation are illustrated schematically.

[0109] like Figure 7aAs shown, the second bristle group 332 is disposed between the first bristle group 331 and the third bristle group 333, and all the second bristle clusters 3321 of the second bristle group 332 are arranged along the third direction. The angle difference between any two adjacent clusters of first bristle clusters 3311 in the first bristle group 331 and the third direction is 2 degrees, that is, the first bristle group 331 is arranged in a fan shape. Similarly, when the angle difference between any two adjacent clusters of third bristle clusters 3331 in the third bristle group 333 and the third direction is 2 degrees, the third bristle group 333 is arranged in a fan shape.

[0110] like Figure 7b As shown, the second bristle group 332 is disposed between the first bristle group 331 and the third bristle group 333, and all the second bristle clusters 3321 of the second bristle group 332 extend along the second preset direction. Some of the first bristle clusters 3311 in the first bristle group 331 extend along the first preset direction and some of the first bristle clusters 3311 extend along the second preset direction. Some of the third bristle clusters 3331 in the third bristle group 333 extend along the first preset direction and some of the third bristle clusters 3331 extend along the second preset direction.

[0111] like Figure 7c As shown, the second bristle group 332 is disposed between the first bristle group 331 and the third bristle group 333. All the first bristle clusters 3311 of the first bristle group 331 and all the third bristle clusters 3331 of the third bristle group 333 extend along a first preset direction, and all the second bristle clusters 3321 of the second bristle group 332 extend along a third preset direction.

[0112] like Figure 7d As shown, the second bristle group 332 is disposed between the first bristle group 331 and the third bristle group 333. All the first bristle clusters 3311 of the first bristle group 331 extend along a first preset direction, all the third bristle clusters 3331 of the third bristle group 333 extend along a second preset direction, and all the second bristle clusters 3321 of the second bristle group 332 extend along a third preset direction.

[0113] It is understood that the extension direction and arrangement of the bristle tufts in the first bristle group 331, the second bristle group 332 and the third bristle group 333 are not limited to the examples above. All arrangements derived therefrom should be included within the protection scope of this application, and the positions, first preset direction and second preset direction of the first bristle group 331 and the third bristle group 333 can be interchanged.

[0114] In some embodiments, the first bristle tuft 3311 includes a plurality of first bristles, wherein the diameters of the first bristles of any two adjacent first bristle tufts 3311 are different. Optionally, the second bristle tuft 3321 includes a plurality of second bristles, wherein the diameters of the second bristles of any two adjacent second bristle tufts 3321 are different. Optionally, the third bristle tuft 3331 includes a plurality of third bristles, wherein the diameters of the third bristles of any two adjacent third bristle tufts 3331 are different.

[0115] In this embodiment, the bristle diameters of any adjacent bristle clusters are different. Bristle clusters with larger diameter bristles are more effective at cleaning stubborn stains, while bristle clusters with smaller diameter bristles are more effective and flexible at cleaning narrow spaces. The alternating arrangement of bristle clusters with different diameter bristles helps to adapt to different types of cleaning targets. Optionally, the diameter of the bristles can be 0.2-0.5 mm. For example, bristle cluster A at the first position in the first bristle group 331 is formed by multiple bristles with a diameter of 0.2 mm, and bristle cluster B at the second position in the first bristle group 331 is formed by multiple bristles with a diameter of 0.3 mm. Multiple bristle clusters A and bristle clusters B are arranged alternately to form the first bristle group 331.

[0116] In some embodiments, the first bristle tuft 3311 has a first diameter, the second bristle tuft 3321 has a second diameter, and the third bristle tuft 3331 has a third diameter. The first, second, and third diameters are all the same size. Alternatively, at least any two of the first, second, and third diameters are different in size.

[0117] In some specific embodiments, the second bristle group 332 is disposed between the first bristle group 331 and the third bristle group 333. The first diameter and the third diameter can be smaller than the second diameter, so that the first bristle group 331, the second bristle group 332 and the third bristle group 333 are arranged to form a cleaning brush that is thick in the middle and thin at both ends. This makes it easier for the cleaning brush to reach some hard-to-reach corners or crevices, thereby improving the cleaning effect.

[0118] In this embodiment, the first bristle tuft 3311, the second bristle tuft 3321 and the third bristle tuft 3331 have the same diameter, and the surface area of ​​the bristle tufts in contact with the target to be cleaned and the pressure borne by each bristle tuft during use are relatively stable and consistent.

[0119] In some specific embodiments, a bristle tuft diameter of 2.5 mm is preferred. Bristle tufts with a diameter that are too large cannot adapt well to some irregularly shaped or space-limited target surfaces to be cleaned, while bristle tufts with a diameter that are too small are not only easy to break but also often have insufficient cleaning power.

[0120] Please see Figure 8 In some embodiments, the end of the first bristle tuft 3311 away from the brush body component 32 forms a first brush surface 3312, the end of the second bristle tuft 3321 away from the brush body component 32 forms a second brush surface 3322, and the end of the third bristle tuft 3331 away from the brush body component 32 forms a third brush surface 3332. At least any two of the first brush surface 3312, the second brush surface 3322, and the third brush surface 3332 have different shapes.

[0121] In this embodiment, at least two of the first brush surface 3312, the second brush surface 3322, and the third brush surface 3332 have different shapes. Setting different brush surface shapes can adapt to a variety of different targets to be cleaned and improve the cleaning effect.

[0122] For example, when dealing with complex surfaces and narrow spaces, the pointed brush head can reach into crevices, corners and other hard-to-reach places for cleaning, while when cleaning large flat surfaces such as walls, the flat brush head can better cover the surface.

[0123] In some embodiments, the angle between the first brush surface 3312 and the third direction is 30-50 degrees, and the angle between the third brush surface 3332 and the third direction is 30-50 degrees.

[0124] like Figure 8 As shown, in this embodiment, a brush surface angle of 30-50 degrees can better conform to curved surfaces, making it easier to clean corners, wall corners, and gaps between cabinets and walls. In some specific embodiments, the cleaning effect is better when the angle γ formed by the first brush surface 3312 and the third brush surface 3332 with the third direction is 45 degrees.

[0125] In some embodiments, multiple bristle clusters of the bristle component 33 form an arc-shaped cleaning surface at the end away from the brush body component 32.

[0126] In this embodiment, the arc-shaped cleaning surface can form a certain arc when it comes into contact with the target surface to be cleaned, which can better fit some curved surfaces and adapt to more application scenarios.
