[0027] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0028] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0029] Cleaning equipment (such as a sweeper) usually includes a roller brush assembly. During the cleaning process, hair and other dirt will be drawn in along the circumferential direction as the roller brush assembly rotates, thereby achieving cleaning. However, a small amount of hair, dirt, etc. will still enter the interior of the roller brush assembly through the structural gaps of the roller brush assembly, such as entering the interior through the gaps at the ends of the roller brush assembly. However, a drive unit or a bearing unit is provided at the end of the roller brush assembly, and the entry of dirt may affect the normal operation of the roller brush, causing abnormal current or structural damage to the roller brush.

[0030] See also Figures 2 to 7As shown, a roller brush assembly 100 provided in an embodiment of the present disclosure includes a shell 110, a roller 120, a roller brush end cover 130, a roller brush cover baffle 140 and a hair stopper 150, wherein the interior of the shell 110 is constructed as a roller brush cavity; the roller 120 is located in the roller brush cavity and is rotatable relative to the roller brush cavity; the roller brush end cover 130 is located at one end of the roller 120; the roller brush cover baffle 140 is located in the roller brush cavity, and the roller brush cover baffle 140 is the structural member closest to the roller 120; there is a gap between the roller brush end cover 130 and the roller brush cover baffle 140; the hair stopper 150 is filled in the gap, and the distance between the hair stopper 150 and the opposite side of the roller brush end cover 130 is S, wherein S≤0mm.

[0031] Specifically, the housing 110 constructs the external structure of the roller brush assembly 100, and defines the internal space as a roller brush chamber, which is used to install and accommodate the roller 120, and the bearing end and the transmission end of the roller 120. The roller 120 is located inside the housing 110. When the roller brush assembly 100 is started, the roller 120 rotates, and the outer surface of the roller 120 achieves a cleaning effect during the rolling process. The roller brush end cover 130 is located at one end of the roller 120, and defines the space of the roller brush chamber in the axial direction of the housing 110 on the side of the housing 110. The roller brush cover baffle 140 is the structural member closest to the roller 120, and the hair blocking member 150 is filled between the roller brush cover baffle 140 and the roller brush end cover 130 to prevent hair from moving between the roller brush cover baffle 140 and the roller brush end cover 130. Furthermore, the distance between the hair blocking member 150 and the roller brush end cover 130 is less than or equal to 0 mm, that is, the hair blocking member 150 and the roller brush end cover are interference fit, which further increases the sealing performance of the hair blocking member 150 .

[0032] It should be noted that during the rotation and cleaning process of the roller 120, the normal path of the cleaned hair is to be collected along the circumference of the roller 120 as the roller 120 rotates, but some hair will enter the interior of the roller brush assembly 100 from the end of the roller brush assembly 100, and the end of the roller brush assembly 100 has a driving structure or a bearing structure. If the hair is entangled in the driving structure or the bearing structure at the end, it will affect the rotation drive of the roller 120, or cause consequences such as structural damage or current abnormality. Therefore, a hair blocking member 150 is provided to prevent hair from entering the roller brush cavity from an abnormal path, thereby preventing the hair from causing abnormal operation of the roller brush assembly 100.

[0033] In one embodiment, if Figures 2 to 5As shown, the roller brush cover baffle is a supporting structure in the roller brush cavity, which can be a plate-shaped structure, a rib structure or a rib structure. In a specific embodiment, the roller brush cover baffle 140 can be a bearing structure or a supporting rib structure between the roller brush end cover 130 and the roller 120. In another specific embodiment, the roller brush cover baffle 140 is a structure on the housing 110 that is opposite to the roller brush end cover 130. In other embodiments, the type of the roller brush cover baffle 140 is not limited, and any structural member closest to the roller 120 falls within the protection scope of this application.

[0034] In one embodiment of the present disclosure, S≥-1mm. The distance between the hair stopper 150 and the roller brush end cover 130 is limited to be greater than or equal to 1mm, which is equivalent to limiting the interference between the hair stopper 150 and the roller brush end cover 130 to be less than or equal to 1mm. A smaller interference can keep the friction force at a smaller value; when the interference is too large, it will increase the assembly difficulty and friction between the hair stopper 150 and the roller brush end cover 130, and even cause deformation and damage to the parts.

[0035] In one embodiment of the present disclosure, the hair blocking member 150 is disposed on the inner wall of the roller brush chamber, and the roller 120 is rotatable relative to the hair blocking member 150 .

[0036] Specifically, the hair stopper 150 is statically arranged on the inner wall of the roller brush cavity, and the hair stopper 150 is fixed by the connection between the interior and the hair stopper 150, and the hair stopper 150 is not installed by the roller brush end cover 130, so that the hair stopper 150 and the roller brush end cover 130 can achieve interference fit. When the roller 120 rotates, the roller 120 can rotate relative to the static roller brush cavity, that is, the hair stopper 150 and the roller brush end cover 130 can rotate.

[0037] In a specific embodiment, the hair blocking member 150 is connected to the roller brush cavity through adhesive or a slot.

[0038] Specifically, the hair blocking member 150 is adhered to the inner wall of the roller brush cavity by means of adhesive backing, and this assembly method facilitates the assembly and disassembly of the hair blocking member 150; the hair blocking member 150 can be connected to the roller brush cavity by being engaged in a groove on the inner wall of the roller brush cavity, and this assembly method has good stability, and the hair blocking member 150 will not shift during the friction process.

[0039] In one embodiment of the present disclosure, Figure 4 and Figure 5 As shown, the radial outer edge surface of the roller brush end cover 130 is opposite to the inner edge surface of the hair blocking member 150, and the distance between the outer edge surface of the roller brush end cover 130 and the inner edge surface of the hair blocking member 150 is S.

[0040] In this embodiment, the gap is located at the radial outer edge surface of the roller brush end cover 130. Therefore, the gap will be filled by setting the hair stopper 150 at the outer edge surface of the roller brush end cover 130 to prevent external hair from entering the interior of the roller brush cavity from the outer surface of the roller brush end cover 130. The hair stopper 150 extends along the outer edge surface of the roller brush end cover 130, forming an inner edge surface of the hair stopper 150 in contact with or interference fit with the roller brush end cover 130.

[0041] In one embodiment of the present disclosure, other surfaces in the roller brush end cover 130 are clearance-matched with the hair blocking member 150 , and the other surfaces are surface areas of the roller brush end cover 130 excluding the radial outer edge surface.

[0042] Specifically, the other surfaces of the roller brush end cover 130 refer to the remaining surfaces after removing the surface in contact with the hair blocking member 150 from all the surfaces of the roller brush end cover 130. The roller brush end cover 130 does not contact with other surfaces, which effectively reduces the contact area between the roller brush end cover 130 and the hair blocking member 150, and can effectively reduce friction, so that the service life of the hair blocking member 150 is longer and the temperature rise during use is less.

[0043] In a specific embodiment, the radial outer surface of the roller brush end cover 130 contacts the inner edge surface of the hair blocking member 150, and one end of the hair blocking member 150 in the axial direction of the roller 120 is located in the internal space of the roller brush cavity and does not contact any surface. The other end of the hair blocking member 150 in the axial direction of the roller 120 is located outside the roller brush cavity and does not contact any surface. The outer edge surface of the hair blocking member 150 opposite to its inner edge surface is adhered to the inner wall of the roller brush cavity by means of adhesive, and is relatively fixed to the inner wall of the roller brush cavity, and does not generate friction.

[0044] In one embodiment of the present disclosure, the hair blocking member 150 is a brush bar, and the bristles of the brush bar are oriented opposite to the direction in which the hair enters the driving end of the roller 120 .

[0045] In this embodiment, the hair blocking member 150 is set as a brush strip, and the brush of the brush strip can generate a large friction force with the hair, and make the hair adhere to the brush, and the hair blocked by the brush will be entangled on the supporting ribs of the end cover, and the brush and the supporting ribs can not only prevent the hair from entering the roller brush cavity, but also collect the hair to prevent the hair from returning to the environment again, thereby improving the cleaning effect of the roller brush assembly 100. In addition, during the rolling process of the roller 120, the end of the brush does not contact the roller 120, and will not rub against the roller 120 continuously, thereby improving the service life of the brush.

[0046] In one embodiment of the present disclosure, Figure 8 As shown, the extension direction of the hair blocking member 150 includes at least one of a U-shape, a circle shape, and a straight line shape.

[0047] In this embodiment, the U-shaped or circular hair stopper 150 extends along the roller brush end cover 130 with a circular outer edge. According to the different structures of the roller brush cover baffle 140, the hair stopper 150 is adaptively set at part or all of the outer edge of the roller brush end cover 130 to form a U-shaped extension direction or a circular extension direction. The U-shaped and circular hair stopper 150 has a better sealing effect; in other embodiments, when the gap of the roller brush cover baffle 140 or the roller brush end cover 130 is linear, the hair stopper 150 is adaptively set to a linear extension direction to fill the gap.

[0048] In one embodiment of the present disclosure, the diameter of the roller brush end cover 130 is the maximum value of the diameter of the radial cross section of the roller brush assembly 100 .

[0049] Specifically, when the diameter of the roller brush end cover 130 is the maximum value of the diameter of the radial section of the roller brush assembly 100, the hair blocking member 150 is interference fit with the outer edge surface of the roller brush end cover 130 to make it difficult for hair to enter the end of the roller brush assembly 100 with the largest end surface.

[0050] In other embodiments, the diameter of the roller brush end cover 130 may not be the maximum diameter of the radial cross-section of the roller brush assembly 100, and the hair blocking member 150 may be interference fit with the outer edge surface of the smaller roller brush end cover 130 to block the gap between the roller brush end cover 130 and the roller brush cover baffle 140.

[0051] The roller brush assembly 100 proposed in the present disclosure, by arranging a hair stopper 150 to fill the gap between the roller brush end cover 130 and the roller brush cover baffle 140, prevents hair from entering the interior of the roller brush assembly 100 through the gap and affecting the operation of the roller brush assembly 100, and the hair stopper 150 and the roller brush end cover 130 have an interference fit to ensure the tightness of the gap filling. In addition, the surface of the roller brush end cover 130 other than the outer edge surface is gap-fitted with the hair stopper 150, and the contact area is only at the outer edge surface. The smaller contact area has less friction and a longer service life.

[0052] In one embodiment of the present disclosure, a cleaning device is also provided. Figure 1 As shown, the cleaning device includes a host 1 and a base station. The host 1 includes the roller brush assembly 100 in any of the above embodiments; the base station is used to clean the host 1, and the base station includes a hair cleaning assembly for cleaning hair on the roller brush assembly 100.

[0053] Specifically, during the operation of the host 1, the hair is wound around the roller brush assembly 100 along the circumference of the roller 120. After the cleaning work is completed, the host 1 returns to the base station, and the hair cleaning assembly in the base station cleans the hair in the roller brush assembly 100.

[0054] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present disclosure (including the claims) is limited to these examples. Based on the concept of the present disclosure, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the embodiments of the present disclosure as described above, which are not provided in detail for the sake of simplicity.

[0055] The embodiments of the present disclosure are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the embodiments of the present disclosure should be included in the scope of protection of the present disclosure.
