Description

Technical Field

[0001] The invention relates to the technical field of surface cleaning devices, in particular to a floor brush and a floor scrubber of a surface cleaning device. Background Art

[0002] Surface cleaning devices, such as vacuum cleaners, floor scrubbers, sweeping robots and other household cleaning products, are generally provided with a floor brush to improve cleaning performance. The floor brush includes a roller brush. When the floor brush is equipped with a water outlet, the roller brush can be moistened, which is conducive to obtaining better cleaning performance. The water outlet is generally extended along the axial direction of the roller brush and is located in the circumference of the roller brush. When the roller brush rotates relative to the water outlet, the liquid supplied by the water outlet moistens the surface of the roller brush. The "water" in the water outlet is just a general term. The "water" refers to liquid, which can be clean water mixed with detergent or pure clean water.

[0003] In the prior art, the water flow rate of the water outlet is generally controlled to be relatively small (this is a specific design considering the residual water on the ground. If the water flow rate is large, it is easy to produce residual water on the ground). Therefore, the water flowing out of the water outlet hole of the water outlet basically falls vertically, and does not diffuse along the designed trumpet-shaped guide groove to evenly wet the roller brush. Therefore, the effect and efficiency of wetting the roller brush are relatively poor. In order to better wet the roller brush and improve the wetting efficiency, the conventional practice is to increase the water outlet holes along the axial extension of the roller brush, which leads to a complex structure, and then the water channel structure connected to each water outlet hole becomes more lengthy and complex.

[0004] Therefore, the present application proposes a floor brush for a surface cleaning device, which is beneficial to improving the effect and efficiency of wetting the roller brush and is beneficial to avoiding additional increase in the complexity of the water channel structure connected to each water outlet. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art and propose a floor brush for a surface cleaning device, which is beneficial to improving the effect and efficiency of wetting the roller brush and avoiding additional increase in the complexity of the water channel structure connected to each water outlet; a floor scrubber is also proposed, including the aforementioned floor brush.

[0006] Compared with the prior art, the present invention proposes a floor brush for a surface cleaning device, comprising a roller brush and a water outlet, the water outlet extending along the axial direction of the roller brush and located in the circumferential direction of the roller brush, when the roller brush rotates relative to the water outlet, the liquid supplied by the water outlet wets the surface of the roller brush, the water outlet is provided with a plurality of water outlet ends arranged in sequence along the axial direction of the roller brush, wherein at least a part of the water outlet ends comprises a first water outlet hole and a second water outlet hole arranged on left and right sides, a first guide surface is provided on the lower side of the first water outlet hole, a second guide surface is provided on the lower side of the second water outlet hole, the first guide surface and the second guide surface are arranged in an eight-shaped shape, the first guide surface and the second guide surface between adjacent water outlet ends form an inverted eight-shaped distribution structure, and the water outlet is provided with a contact edge along the axial direction of the roller brush between the lower end of the first guide surface and the lower end of the second guide surface of the inverted eight-shaped distribution structure, and the contact edge is arranged in contact with the outer periphery of the roller brush.

[0007] After adopting the above structure, compared with the prior art, the present invention has the following advantages:

[0008] The present invention is improved in that, on the one hand, the first guide surface and the second guide surface between adjacent water outlet ends form an inverted eight-shaped distribution structure, so that the liquid can be better guided to between adjacent water outlet ends through the guidance of the first guide surface and the second guide surface, thereby achieving the purpose of coverage when the number of water outlet ends is small, and on the other hand, the water outlet part is provided with a close-fitting edge along the axial direction of the roller brush between the lower end of the first guide surface and the lower end of the second guide surface of the inverted eight-shaped distribution structure, and the close-fitting edge is provided in close contact with the outer periphery of the roller brush, so that the outer side edge of the first guide surface, the close-fitting edge, and the outer side edge of the second guide surface sequentially form a basin-shaped edge structure, which can better transport the liquid to between adjacent water outlet ends, and at the same time, the first guide surface and the second guide surface themselves can also moisten the outer periphery of the roller brush through their respective outer sides when receiving the liquid flowing through.

[0009] In summary, the floor brush of a surface cleaning device proposed in the present disclosure is beneficial to improving the effect and efficiency of wetting the roller brush, and is beneficial to avoiding additional increase in the complexity of the water channel structure connected to each water outlet.

[0010] In some embodiments, the inverted figure eight distribution structure is arranged between each adjacent water outlet end.

DETAILED DESCRIPTION

[0026] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0027] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0028] like Figures 1 to 7 The present invention shows a floor brush of a surface cleaning device, comprising a roller brush 1 and a water outlet 4, wherein the water outlet 4 is extended along the axial direction of the roller brush 1 and is located in the circumferential direction of the roller brush 1. When the roller brush 1 rotates relative to the water outlet 4, the liquid supplied by the water outlet 4 wets the surface of the roller brush 1. The water outlet 4 is provided with a plurality of water outlet ends 5 arranged in sequence along the axial direction of the roller brush 1, wherein at least a part of the water outlet ends 5 comprises a first water outlet hole 6 and a second water outlet hole 7 arranged on the left and right sides, a first guide surface 8 is provided at the lower side of the first water outlet hole 6, a second guide surface 9 is provided at the lower side of the second water outlet hole 7, the first guide surface 8 and the second guide surface 9 are arranged in an eight-shaped shape, the first guide surface 8 and the second guide surface 9 between adjacent water outlet ends 5 form an inverted eight-shaped distribution structure, and the water outlet 4 is provided with a contact edge 10 along the axial direction of the roller brush 1 between the lower end of the first guide surface 8 and the lower end of the second guide surface 9 of the inverted eight-shaped distribution structure, and the contact edge 10 is arranged in contact with the outer peripheral portion 3 of the roller brush 1.

[0029] In order to facilitate water flow, Figure 5 , 6 As shown in Figures 7 and 8, the water outlet 4 is generally arranged vertically.

[0030] Since the outer peripheral portion 3 of the roller brush 1 is generally a water-absorbing cleaning cotton that can be squeezed and deformed, and the outer peripheral portion 3 is supported by the roller 2, and as Figure 4 As shown, the outer edge of the first guide surface 8, the adjacent edge 10, and the outer edge of the second guide surface 9 of the present invention form a basin-shaped edge structure 12 in sequence, so when the absorbent cleaning cotton passes through the water outlet 4, the absorbent cleaning cotton and the basin-shaped edge structure 12 form an extrusion fit, and the absorbent cleaning cotton is wetted by the liquid.

[0031] In some embodiments, Figure 4 As shown, the side of the water outlet 4 facing the roller brush 1 is arranged as a concave surface, and each water outlet end 5 is arranged in the concave surface, and the lower side of the concave surface serves as a contact edge 10, which means that the basin-shaped edge structure 12 has a certain depth. Therefore, even if more liquid is supplied, it is not easy to leak, but it is beneficial to moisten the outer periphery 3 of the roller brush 1. In this way, by controlling the liquid supply amount, it provides certain technical means to control how to maintain a balance between moistening and reducing water residue.

[0032] Furthermore, the concave surface is a V-shaped concave surface, and the lower side of the V-shaped concave surface serves as the abutting edge 10, and the water outlet end 5 is located at the bottom of the V-shaped concave surface.

[0033] like Figure 1 The figure shows a front view of a water outlet portion 4. It can be seen that all water outlet portions 4 include a first water outlet hole 6 and a second water outlet hole 7 arranged on the left and right sides, and the inverted eight-shaped distribution structure is arranged between each adjacent water outlet end 5, so that only a small number of water outlet portions 4 are needed to form a larger coverage area.

[0034] like Figure 1 , 2 As shown, a screw hole 13 for mounting on a floor brush is provided on the water outlet 4, and the first guide surface 8 and the second guide surface 9 can be arranged to avoid the screw hole 13 when encountering the screw hole 13.

[0035] Figure 1 The arrow shown in the figure indicates the direction of water flow. Since the adjacent edge 10 is arranged in contact with the outer peripheral portion 3 of the roller brush 1, the liquid flowing out from the lower end of the first guide surface 8 and the lower end of the second guide surface 9 of the inverted eight-shaped distribution structure will further flow toward each other along the adjacent edge 10, thereby improving the coverage.

[0036] When the water outlet end 5 is located at the left and right ends of the water outlet part 4, since the two ends of the water outlet part 4 are edges, whether to set the first guide surface 8 at the left end of the water outlet part 4 and the second guide surface 9 at the right end of the water outlet part 4 can be set according to the coverage needs, but it is recommended to set the first guide surface 8 and the second guide surface 9 at the water outlet end 5 between the left and right ends of the water outlet part 4.

[0037] In some embodiments, Figure 1 , 2 As shown, the first water outlet hole 6 and the second water outlet hole 7 are arranged adjacent to each other. In this way, the first water outlet hole 6 and the second water outlet hole 7 can be separated from one water outlet hole, which is conducive to simplifying the waterway structure.

[0038] Furthermore, a partition 11 is provided between the first water outlet 6 and the second water outlet 7, and the lower end of the partition 11 is connected to the upper end of the first guide surface 8 and the upper end of the second guide surface 9. In this way, the flowing liquid is collected and guided as much as possible.

[0039] The present disclosure also provides a floor scrubber, comprising a body, a handle and a floor brush, wherein the floor brush is connected to the lower end of the body.

[0040] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0041] The above description is only an illustrative embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
