Description

Technical Field

[0001] This utility model relates to the technical field of surface cleaning devices, specifically a floor brush and floor scrubber for surface cleaning devices. Background Technology

[0002] Surface cleaning devices, such as vacuum cleaners, floor scrubbers, and robotic vacuum cleaners, are typically equipped with floor brushes to enhance cleaning performance. These floor brushes include roller brushes. When a water outlet is provided on the floor brush, the roller brush becomes wet, which helps to achieve better cleaning performance. The water outlet is generally arranged along the axial direction of the roller brush and is located around the circumference 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 term "water" in the water outlet is a general term that refers to liquid, which can be water mixed with detergent or plain water.

[0003] In existing technologies, the water flow rate of the water outlet is generally controlled to be relatively small (this is a specific design to account for water residue on the ground; if the water flow rate is large, water residue on the ground is more likely to occur). Therefore, the water flowing out of the water outlet holes of the water outlet section basically falls vertically, rather than spreading and flowing along the designed funnel-shaped guide channel to evenly wet the roller brush. As a result, the wetting effect and efficiency of the roller brush are relatively poor. In order to better wet the roller brush and improve the wetting efficiency, the conventional approach is to add more water outlet holes along the axial direction of the roller brush. This leads to a complex structure, which in turn makes the water channel structure connecting each water outlet hole more lengthy and complex.

[0004] Therefore, this 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 also helps to avoid adding extra complexity to the water channel structure connected to each water outlet. Utility Model Content

[0005] The technical problem to be solved by this utility model 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 to avoiding the additional complexity of the water channel structure connected to each water outlet; it also proposes a floor scrubbing machine including the aforementioned floor brush.

[0006] Compared with the prior art, this utility model proposes a floor brush for a surface cleaning device, including a roller brush and a water outlet. The water outlet extends along the axial direction of the roller brush and is located around the circumference 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 has a plurality of water outlets arranged sequentially along the axial direction of the roller brush, wherein at least a portion of the water outlets include a first water outlet hole and a second water outlet hole arranged on the left and right sides. A first guide surface is provided on the lower side of the first water outlet hole, and 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 a V-shape. The first guide surface and the second guide surface between adjacent water outlets form an inverted V-shape distribution structure. Furthermore, the water outlet has a contacting 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 in the inverted V-shape distribution structure. The contacting edge is in contact with the outer periphery of the roller brush.

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

[0008] This disclosure improves upon existing methods by, on the one hand, establishing an inverted V-shaped distribution structure between the first and second guide surfaces of adjacent water outlets. This allows for better guidance of the liquid to flow between adjacent water outlets, achieving coverage even with a limited number of outlets. On the other hand, the water outlet has an adhering edge along the axial direction of the roller brush between the lower ends of the first and second guide surfaces of this inverted V-shaped distribution structure. This adhering edge is in contact with the outer periphery of the roller brush. Thus, the outer edges of the first guide surface, the adhering edge, and the outer edges of the second guide surface sequentially form a basin-shaped edge structure, better conveying the liquid between adjacent water outlets. Simultaneously, the first and second guide surfaces themselves can wet the outer periphery of the roller brush through their respective outer edges when receiving the liquid flow.

[0009] In summary, the floor brush of the surface cleaning device proposed in this disclosure is beneficial to improving the effect and efficiency of wetting the roller brush, and also helps to avoid adding extra complexity to the water channel structure connected to each water outlet.

[0010] In some embodiments, the inverted V-shaped distribution structure is provided between each adjacent water outlet.

[0011] In some embodiments, the first water outlet and the second water outlet are arranged adjacent to each other.

[0012] In some embodiments, a partition is provided between the first water outlet and the second water outlet, and the lower end of the partition is connected to the upper end of the first guide surface and the upper end of the second guide surface, respectively.

[0013] In some embodiments, the side of the water outlet facing the roller brush is configured as a concave surface, and each water outlet end is disposed in the concave surface.

[0014] In some embodiments, the lower side of the concave surface serves as the adjacent edge.

[0015] In some embodiments, the concave surface is a V-shaped concave surface, and the lower side of the V-shaped concave surface serves as the contact edge.

[0016] In some embodiments, the water outlet is located at the bottom of the V-shaped concave surface. Attached Figure Description

The embodiments described below are merely examples, and other obvious variations will arise for those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

Therefore, the above terms should not be construed as limitations on this utility model.

[0028] like Figures 1 to 7 The image shows a floor brush for a surface cleaning device, comprising a roller brush 1 and a water outlet 4. The water outlet 4 extends along the axial direction of the roller brush 1 and is located circumferentially around 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 has a plurality of water outlets 5 arranged sequentially along the axial direction of the roller brush 1, wherein at least a portion of the water outlets 5 includes 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 on the lower side of the first water outlet hole 6, and a second guide surface 9 is provided on the lower side of the second water outlet hole 7. The first guide surface 8 and the second guide surface 9 are arranged in a V-shape. The first guide surface 8 and the second guide surface 9 between adjacent water outlets 5 form an inverted V-shape distribution structure. Furthermore, the water outlet 4 has a contacting edge 10 arranged 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 in the inverted V-shape distribution structure. The contacting edge 10 is in contact with the outer periphery 3 of the roller brush 1.

[0029] To facilitate water flow, such as Figure 5 , 6 As shown in Figures 7 and 8, the water outlet 4 is generally installed vertically.

[0030] Since the outer periphery 3 of the roller brush 1 is generally made of compressible, deformable absorbent cleaning cotton, and the outer periphery 3 is supported by the roller 2, and, as Figure 4 As shown, the outer side of the first guide surface 8, the adjacent edge 10, and the outer side of the second guide surface 9 of this disclosure sequentially form a basin-shaped edge structure 12. Therefore, when the absorbent cleaning cotton passes through the water outlet 4, the absorbent cleaning cotton and the basin-shaped edge structure 12 form a compression fit, and the absorbent cleaning cotton is wetted by the liquid.

[0031] In some embodiments, such as Figure 4As shown, the side of the water outlet 4 facing the roller brush 1 is set as a concave surface, and each water outlet end 5 is set in the concave surface. The lower side of the concave surface serves as the adjacent edge 10, which means that the basin-shaped edge structure 12 has a certain depth. Therefore, even if a large amount of liquid is supplied, it is not easy to leak. Instead, it is beneficial to wet the outer periphery 3 of the roller brush 1. In this way, by controlling the amount of liquid supply, a certain technical means is provided to control how to maintain a balance between wetting 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 adjacent edge 10, while the water outlet 5 is located at the bottom of the V-shaped concave surface.

[0033] like Figure 1 The image shows a front view of a water outlet section 4. It can be seen that all water outlet sections 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 V-shaped distribution structure is arranged between each adjacent water outlet end 5. In this way, only a small number of water outlet sections 4 are needed to form a larger coverage area.

[0034] like Figure 1 , 2 As shown, the water outlet 4 is provided with screw holes 13 for mounting on the floor brush. The first guide surface 8 and the second guide surface 9 can be configured to avoid the screw holes 13.

[0035] Figure 1 The arrows shown indicate the direction of water flow. Since the contact edge 10 is in contact with the outer periphery 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 V-shaped distribution structure will flow towards each other along the contact edge 10, thereby improving the coverage.

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

[0037] In some embodiments, such as Figure 1 , 2 As shown, the first water outlet 6 and the second water outlet 7 are arranged adjacent to each other. In this way, the first water outlet 6 and the second water outlet 7 can be separated from a single water outlet, which helps to simplify the water circuit 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, respectively. In this way, the flowing liquid is collected and guided as much as possible.

[0039] This disclosure also proposes a floor scrubber, including a body, a handle and a floor brush, with the aforementioned floor brush connected to the lower end of the body.

[0040] When understanding this disclosure, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that is understood, so I will not elaborate further here.

[0041] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
