[0002] With economic development and social progress, people have increasingly higher demands for quality of life, and cleaning equipment has gradually entered people's lives. The most common cleaning equipment includes floor scrubbers, vacuum cleaners, and robotic vacuum cleaners.

[0051] See Figure 1 One embodiment of this application provides a floor brush assembly 100 for use in cleaning equipment, specifically, the cleaning equipment is a floor scrubber that integrates washing and mopping. It should be understood that in other embodiments, the floor brush assembly 100 may also be disposed in other cleaning equipment, which is not limited here.

[0052] The following description uses the application of the floor brush assembly 100 in a floor scrubber as an example to illustrate the technical solution of this application. This embodiment is only used as an example and does not limit the technical scope of this application. Furthermore, unnecessary components are omitted in the drawings of the embodiment to clearly show the technical features of this application.

[0053] The floor scrubber includes a body and a brush assembly 100, which is mounted on the body. The brush assembly 100 includes a main body and a roller brush 20, connected to the body, with the roller brush 20 pivotally connected to the main body. When the floor scrubber needs to perform cleaning work, the roller brush 20 of the brush assembly 100 rotates relative to the main body around an axis to carry dust from the floor into the scrubber's interior. Furthermore, the floor scrubber also includes a clean water tank, a wastewater tank, and a power unit mounted on the body. Water in the clean water tank flows to the roller brush 20 to mop the floor under the rolling action of the roller brush 20. The power unit provides power for the dust and wastewater generated during mopping, allowing the dust and wastewater to enter the wastewater tank for collection.

[0054] See Figures 1-3 The body includes a housing and an end plate 10, and the roller brush 20 has at least one pivot end 21 that is pivotally connected to the end plate 10. That is, the end of the roller brush 20 that is pivotally connected to the end plate 10 is defined as the pivot end 21. When one axial end of the roller brush 20 is pivotally connected to the end plate 10, the roller brush 20 has one pivot end 21; when both axial ends of the roller brush 20 are pivotally connected to the end plate 10, the roller brush 20 has two pivot ends 21.

[0055] Along the axial direction of the roller brush 20, the end plate 10 is movably connected to both the housing and the roller brush 20, allowing the end plate 10 to switch between a first position and a second position relative to the pivot end 21. (See also...) Figures 1-3 In the first position, the axial end face 211 of the pivot end 21 is located within the outer surface 11 of the end plate 10. Specifically, the axial end face 211 of the pivot end 21 is located within the inner surface 12 of the end plate 10 to avoid the end plate 10 interfering with the rotation of the roller brush 20. (See also...) Figures 4-6 In the second position, at least a portion of the axial end face 211 of the pivot end 21 is flush with or protrudes from the outer surface 11 of the end plate 10.

[0056] With the above configuration, when the end plate 10 is in the first position relative to the pivot end 21, the axial end face 211 of the pivot end 21 is located within the outer surface 11 of the end plate 10. The roller brush 20 can rotate around the aforementioned axis to bring the dust from the ground into the interior of the floor scrubber. At this time, it is convenient to clean open areas, i.e., convenient to clean non-corner areas. When the end plate 10 is in the second position relative to the pivot end 21, at least a portion of the axial end face 211 of the pivot end 21 is flush with or protrudes from the outer surface 11 of the end plate 10. At this time, the body can no longer interfere with the roller brush 20, and the roller brush 20 can achieve edge cleaning, eliminating cleaning dead corners.

[0057] It should be noted that the outer surface 11 of the end plate 10 is the surface on the outer side of the end plate 10 in the axial direction of the roller brush 20. The inner surface 12 of the end plate 10 is the surface on the inner side of the end plate 10 in the axial direction of the roller brush 20.

[0058] In one embodiment, the body includes a driving member, one end of the roller brush 20 is connected to the driving member, and the other end of the roller brush 20 forms a pivot end 21 (see...). Figure 3 This allows one end of the roller brush 20 to perform edge cleaning along the axis, and since the other end of the roller brush 20 is connected to the drive unit, the stability of the roller brush 20 mounted on the body is ensured.

[0059] Specifically, the driving component includes a driving unit, a first pulley, a second pulley, and a belt. The first pulley is connected to the driving unit, the second pulley is connected to the roller brush 20, and the belt is sleeved around the first and second pulleys. The driving unit drives the first pulley to rotate, and the first pulley drives the second pulley to rotate via the belt, thereby driving the roller brush 20 to rotate. Specifically, the driving unit is a motor. It should be understood that in some embodiments, the driving component is not limited to belt drive; it can also be gear drive, or the driving unit can directly drive the roller brush 20 to rotate.

[0060] In another embodiment, the roller brush 20 has two pivot ends 21 that are pivotally connected to the end plate 10. That is, both ends of the roller brush 20 in the axial direction are pivotally connected to the body through the end plate 10, so that both ends of the roller brush 20 in the axial direction can achieve edge cleaning. Compared with the prior art where one end of the roller brush 20 is suspended to achieve edge cleaning, this arrangement allows the roller brush 20 to be firmly connected to the body, improving the stability of the entire structure.

[0061] In one specific embodiment, two end plates 10 connected to two pivot ends 21 are integrally formed. The integrally formed molded body of the two end plates 10 can switch between a first position and a second position relative to either pivot end 21. It should be noted that the first and second positions of the molded body relative to the two pivot ends 21 are not the same. Defining the two pivot ends 21 of the roller brush 20 as the first pivot end 21 and the second pivot end 21, when the molded body is in the first position relative to the first pivot end 21, the axial end face 211 of the first pivot end 21 is located within the outer surface 11 of the end plate 10 at that end. When the molded body is in the second position relative to the first pivot end 21, at least a portion of the axial end face 211 of the first pivot end 21 is flush with or protrudes from the outer surface 11 of the end plate 10 at that end. When the molded body is in the first position relative to the second pivot end 21, the axial end face 211 of the second pivot end 21 is located within the outer surface 11 of the end plate 10 of that end. When the molded body is in the second position relative to the second pivot end 21, at least a portion of the axial end face 211 of the second pivot end 21 is flush with or protrudes from the outer surface 11 of the end plate 10 of that end.

[0062] In another specific embodiment, the body includes a first end plate and a second end plate that are separately configured. A first pivot end 21 is pivotally connected to the first end plate, and a second pivot end 21 is pivotally connected to the second end plate. The first end plate switches between a first position and a second position relative to the first pivot end 21. When the first end plate is in the first position, the axial end face 211 of the first pivot end 21 is located within the outer surface 11 of the first end plate. When the first end plate is in the second position, at least a portion of the axial end face 211 of the first pivot shaft 46 is flush with or protrudes from the outer surface 11 of the first end plate. The second end plate switches between a first position and a second position relative to the second pivot end 21. When the second end plate is in the first position, the axial end face 211 of the second pivot end 21 is located within the outer surface 11 of the second end plate. When the second end plate is in the second position, at least a portion of the axial end face 211 of the second pivot shaft 46 is flush with or protrudes from the outer surface 11 of the second end plate.

[0063] In one embodiment, see Figure 7 and Figure 8The floor brush assembly 100 also includes an elastic element 30, which is disposed between the end plate 10 and the roller brush 20. When the end plate 10 switches from the first position to the second position, the elastic element 30 elastically deforms and stores force, providing a restoring force for the end plate 10 to switch from the second position to the first position. When edge cleaning is required, a force (which can be applied manually, by the corner wall, or by the internal structure of the floor scrubber) is applied to the end plate 10, causing it to switch from the first position to the second position. At this time, the elastic element 30 elastically deforms and stores force. After edge cleaning, the elastic element 30 provides a restoring force to switch the end plate 10 from the second position back to the first position. In this way, the end plate 10 can automatically reset, avoiding the need for manual switching or other additional structural settings to switch the end plate 10 from the second position to the first position, which is more convenient.

[0064] In one embodiment, see further. Figure 3 The end plate 10 includes a connecting end 13 and a suspended end 14. The connecting end 13 is connected to the housing, and the pivoting end 21 is connected to the suspended end 14. When the end plate 10 is in the second position, at least a portion of the end of the suspended end 14 away from the connecting end 13 is accommodated within the pivoting end 21. That is, in this embodiment, the roller brush 20 is a hollow cylindrical structure, and when the end plate 10 is in the second position, at least a portion of the end of the suspended end 14 away from the connecting end 13 is accommodated within the pivoting end 21 of the roller brush 20. It should be understood that in other embodiments, at least a portion of the axial end face 211 of the pivoting end 21 can be flush with or protrude from the outer surface 11 of the end plate 10 in other ways, and the specific method is not limited here.

[0065] Furthermore, a clearance portion 141 is provided at the end of the suspended end 14 near the connecting end 13. When the end plate 10 is in the second position, a portion of the pivot end 21 passes through the clearance portion 141 (see...). Figure 6 Within the pivot end 21, the entire end of the suspended end 14 away from the connecting end 13 is housed within the pivot end 21, and the entire axial end face 211 of the pivot end 21 is flush with or protrudes from the outer surface 11 of the end plate 10. Specifically, the aforementioned clearance portion 141 is a clearance hole axially penetrating through the end plate 10. It should be understood that, in another embodiment, the aforementioned clearance portion may also be a clearance groove axially penetrating through the end plate 10 of the roller brush 20.

[0066] In another embodiment, when the end plate 10 is in the second position, a portion of the pivot end 21 abuts against the inner surface 12 of the suspended end 14 and undergoes elastic deformation. The portion of the suspended end 14 away from the connecting end 13 is accommodated in the pivot end 21. A portion of the axial end face 211 of the pivot end 21 is flush with or protrudes from the outer surface 11 of the end plate 10.

[0067] Specifically, the thickness of the first end plate and the second end plate in the axial direction of the roller brush 20 is set to 3mm-10mm, preferably 5mm. It should be understood that in some embodiments, the thickness of the end plate 10 is not limited.

[0068] See Figure 9 and Figure 10 The floor brush assembly 100 also includes a rotating sleeve assembly 40, which is connected to the end plate 10. The roller brush 20 is disposed outside the rotating sleeve assembly 40, and the roller brush 20 and the end plate 10 are pivotally connected via the rotating sleeve assembly 40. The rotating sleeve assembly 40 can slide within the roller brush 20 in the axial direction, so that the end plate 10 can switch between a first position and a second position.

[0069] In one embodiment, see Figure 8 and Figure 10 The rotating sleeve assembly 40 includes a rotating sleeve 41, which is fixedly connected to the end plate 10 and pivotally connected to the roller brush 20. The roller brush 20 has a protruding stepped portion 23, and an elastic element 30 is disposed between the rotating sleeve 41 and the stepped portion 23. When the end plate 10 switches from a first position to a second position, the elastic element 30 elastically deforms and stores force, providing a restoring force for the end plate 10 when switching from the second position to the first position.

[0070] In this embodiment, when edge cleaning is required, a force is applied to the end plate 10, causing the end plate 10 to drive the rotating sleeve 41 to move inward into the roller brush 20. The end plate 10 switches from the first position to the second position, at which time the elastic element 30 elastically deforms and stores force. When the end plate 10 is released, it automatically switches from the second position to the first position under the restoring force of the elastic element 30. Specifically, the elastic element 30 is a spring.

[0071] In another embodiment, see Figure 11 The rotating sleeve assembly 40 also includes a locking member 42, which is disposed within the roller brush 20. The rotating sleeve 41 is rotatably disposed within the locking member 42, and the elastic member 30 abuts against the locking member 42 and the stepped portion 23. In the axial direction of the roller brush 20, the locking member 42, the rotating sleeve 41, and the end plate 10 move synchronously relative to the roller brush 20. The locking member 42 is in a third position relative to the roller brush 20 (see...). Figure 3 ) and the fourth position (see Figure 6The end plate 10 is switched between the three positions. When the locking member 42 is in the third position, the end plate 10 is locked to the first position; when the locking member 42 is in the fourth position, the end plate 10 is locked to the second position. This avoids relative shaking between the end plate 10 and the roller brush 20 during the operation of the floor scrubber, thus improving the stability of the roller brush 20.

[0072] In this embodiment, when edge cleaning is required, a force is applied to the end plate 10, causing the end plate 10 to drive the rotating sleeve 41 and locking member 42 to move into the roller brush 20. The end plate 10 switches from the first position to the second position, and the locking member 42 switches from the third position to the fourth position. At this time, the elastic member 30 elastically deforms and stores force. When the end plate 10 is released, a force is applied to the locking member 42 (e.g., by kicking the outer circumferential surface of the roller brush 20, causing the roller brush 20 to elastically deform), allowing the locking member 42 to move relative to the roller brush 20. At this time, the restoring force provided by the elastic member 30 causes the locking member 42 to move from the fourth position to the third position. Since the end plate 10 and the locking member 42 move synchronously, the end plate 10 moves from the second position to the first position.

[0073] Further reading Figure 11 The outer wall of the locking member 42 and the inner wall of the roller brush 20 are provided with a first locking groove 431 and a second locking groove 432, respectively, and a locking protrusion 44 is provided on the other. The locking protrusion 44 cooperates with the first locking groove 431 or the second locking groove 432 to restrict the locking member 42 to a third position or a fourth position. Specifically, the cross-sectional shape of the first locking groove 431 and the second locking groove 432 is arc-shaped, and the cross-sectional shape of the locking protrusion 44 is also arc-shaped to facilitate the locking protrusion 44 to slide into or out of the locking groove.

[0074] In one specific embodiment, the first locking groove 431 and the second locking groove 432 are provided on the inner wall of the roller brush 20, and the locking protrusion 44 is provided on the outer wall of the locking member 42. Specifically, a guide groove 22 is provided on the inner wall of the roller brush 20, and the first locking groove 431 and the second locking groove 432 are provided on the bottom wall of the guide groove 22. The guide groove 22 serves to guide the locking protrusion 44.

[0075] The rotating assembly 40 also includes a resilient locking arm 45. One end of the locking arm 45 is connected to the outer wall of the locking member 42 or the inner wall of the roller brush 20, and the other end of the locking arm 45 is provided with a locking protrusion 44. When the locking member 42 moves relative to the roller brush 20, the locking arm 45 elastically deforms and stores force. That is, during the process of the locking protrusion 44 switching between the first locking groove 431 and the second locking groove 432, the locking arm 45 elastically deforms and stores force to facilitate the sliding of the locking protrusion 44 into the first locking groove 431 or the second locking groove 432.

[0076] Furthermore, one end of the locking arm 45 is connected to the outer wall of the locking member 42, and the other end extends towards the end plate 10. The angle between the locking arm 45 and the locking member 42 ranges from 3° to 8°, preferably 5°. This allows the locking arm 45 to easily deform under stress, facilitating the switching of the end plate 10 between the first and second positions. It is understood that in other embodiments, the locking arm 45 may be configured in other ways, which are not limited here.

[0077] In one specific implementation, at least two locking arms 45 are provided circumferentially spaced on the outer wall of the locking member 42. Each locking arm 45 has a locking protrusion 44 at its end away from the locking member 42. Correspondingly, the number of first locking grooves 431 and second locking grooves 432 in the circumferential direction corresponds to the number of locking arms 45. In this way, if one set of locking structures (including locking grooves, locking arms 45 and locking protrusions 44) is damaged, the other set of locking structures can still function, ensuring the stability of the structural movement.

[0078] Specifically, the locking arm 45 includes two symmetrically arranged locking protrusions 44, and there are also two first locking grooves 431 and two second locking grooves 432. In another embodiment, there may be four locking arms 45, four locking protrusions 44, and four first locking grooves 431 and four second locking grooves 432.

[0079] The rotating sleeve assembly 40 also includes a rotating shaft 46 and a bearing 47. The bearing 47 is located in one of the locking member 42 and the rotating sleeve 41, and the rotating shaft 46 is located in the other of the locking member 42 and the rotating sleeve 41 and passes through the bearing 47. This facilitates the rotation of the roller brush 20 relative to the end plate 10.

[0080] Specifically, the bearing 47 is located inside the rotating sleeve 41, one end of the rotating shaft 46 is connected to the locking member 42, and the other end passes through the bearing 47. When cleaning open ground, the locking member 42, the rotating shaft 46, and the roller brush 20 all rotate relative to the rotating sleeve 41 and the end plate 20.

[0081] Furthermore, the rotating sleeve 41 includes a separate connecting sleeve 411 and a bushing 412. The connecting sleeve 411 is connected to the end plate 10, and the bushing 412 is disposed inside the connecting sleeve 411. The rotating shaft 46 is fixedly connected to one of the locking member 42 and the bushing 412, and pivotally connected to the other. This facilitates the installation of the rotating sleeve 41. It should be understood that in some other embodiments, the connecting sleeve 411 and the bushing 412 may also be integrally formed.

[0082] Specifically, the end plate 10 is provided with a cross boss 50, the cross hole 413 of the connecting sleeve 411 mates with the cross boss 50, and the fastener 60 passes through the connecting sleeve 411 and the cross boss 50 to fix the two. Specifically, the fastener 60 is a screw.

[0083] The working principle of the floor scrubber provided in a specific embodiment of this application is as follows (in conjunction with...) Figures 1-6 ):

[0084] When cleaning the corners, a force is applied to the end plate 10 (this force can be applied manually, from the wall, or from the internal structure of the floor scrubber). The end plate 10, connecting sleeve 411, bushing 412, bearing 47, rotating shaft 46, and locking element 42 all slide synchronously to the right (e.g., Figure 3 (as shown in the direction). The locking arm 45 on the locking member 42 elastically deforms under the above-mentioned force, and the locking protrusion 44 slides from the first locking groove 431 into the second locking groove 432. Specifically, the end plate 10, connecting sleeve 411, bushing 412, bearing 47, rotating shaft 46 and locking member 42 all slide synchronously to the right by 6mm, until the lower end of the end plate 10 slides into the interior of the roller brush 20, until its outer surface 11 (left side surface) is flush with the left end face of the roller brush 20, and the elastic member 30 is compressed and deformed (e.g. Figure 6 (as shown in the direction).

[0085] It should be noted that when cleaning the corners of the floor, the roller brush 20 cannot rotate relative to the end plate 10 due to the restriction of the end plate 10. The roller brush 20 slides between the floor or wall panel to achieve cleaning.

[0086] When corners and edges are not needed, apply force to the roller brush 20, such as by kicking the outer surface of the roller brush 20 or by applying force to the roller brush 20 through the internal structure of the floor scrubber. The locking protrusion 44 disengages from the second locking groove 432. Under the restoring force of the elastic member 30, the locking member 42 drives the locking protrusion 44 to slide from the second locking groove 432 into the first locking groove 431. That is, after the locking member 42 moves 6mm to the left, the locking protrusion 44 is locked in the first locking groove 431, and the end plate 10 slides out of the roller brush 20 (e.g., Figure 3 (as shown in the direction). At this time, the elastic element 30 elastically resets, and the elastic element 30 no longer applies force to the locking element 42 or the roller brush 20. There is a gap between the axial end face 211 of the roller brush 20 and the inner surface 12 of the end plate 10 to avoid the end plate 10 interfering with the rotation of the roller brush 20. Specifically, the gap between the axial end face 211 of the roller brush 20 and the inner surface 12 of the end plate 10 is greater than or equal to 1 mm.

[0087] Another embodiment of this application also provides a cleaning device including the above-described floor brush assembly 100, specifically, the cleaning device is a floor scrubber.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
