Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of cleaning equipment, and particularly relates to a rolling brush assembly, a cleaning head device, a cleaning equipment and a method. BACKGROUND

[0002] The surface cleaning device in the prior art, such as the surface cleaning device for wet cleaning of hard floor or short pile carpet, usually has one or more rolling brushes or cleaning discs made of woolen material, which can scrub stubborn dirt on the floor by adding water or water / cleaner mixture. When the surface cleaning device moves on the dirt, the dirt that has been scrubbed off by the rolling brush and dissolved by water or water / cleaner mixture is sucked by the cleaning head arranged along the rolling brush movement direction. In the technology of setting the cleaning disc, the cleaning head can not be set, and the dirt is directly adsorbed by the cleaning material on the cleaning disc. Scrubbing is a cleaning process to remove stains attached to the floor surface.

[0003] The prior art usually sets a nozzle on the cleaning head, which is distributed along the axial direction of the rolling brush. By applying a certain pressure to the fluid, the fluid is sprayed onto the rolling brush in front of the nozzle, and a wet surface is formed on the surface of the rolling brush. The wet surface rubs against the ground to remove dirt and dust.

[0004] EP2337475B1 discloses a fluid dispensing brush assembly and a method for operating the same. The brush assembly has a hollow rolling brush formed by a hollow cylinder. One end of the hollow rolling brush is closed, and the other end can be connected to a cleaning liquid supply mechanism. The cylindrical wall of the shaft of the rolling brush has multiple rows of ridges, and multiple orifices are arranged therebetween. Water supplied into the hollow cylinder via the water supply can be thrown outwards via the orifices distributed in the water channels formed by adjacent ridges through the water channels.

[0005] However, due to the limited height of the ridges and the large water storage space in the rolling brush, when the rolling brush is running at high speed, it cannot be fully guaranteed that the cleaning liquid is fully thrown out, and the cleaning liquid may cross the ridges, so that the ridges lose their effect, and it is often difficult to guarantee that the cleaning liquid is uniformly thrown out, and uneven water stains may still occur.

[0006] In addition, there is pressure dissipation to the distal end of the water inlet in the prior art, and the water on the rolling brush is uneven. Thus, liquid is unevenly distributed on the rolling brush, i.e., there is more liquid near the water inlet, and less liquid away from the water inlet. Thus, at the beginning of the cleaning process, coarse water stains and fine water stains appear on the cleaning surface. This is an undesirable result for "line cleaning" when "face cleaning" is desired. Therefore, a technology is needed to solve the above problems. SUMMARY

[0007] To solve at least one of the above technical problems, the present disclosure provides a rolling brush assembly, a cleaning head device, a cleaning apparatus, and a method.

[0107] The present disclosure will be further described in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are merely exemplary features of various details and are not intended to limit the disclosure. In addition, it should be noted that only parts related to the present disclosure are shown in the drawings for ease of description.

[0108] It should be noted that the embodiments and features in the embodiments of the present disclosure can be combined with each other without conflict. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

Therefore, unless otherwise specified, the features of various embodiments / instances can be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of the present disclosure.

[0110] The use of cross-hatching and / or shading in the drawings is generally used to illustrate the boundaries and / or transitions from one portion of a part to another portion of the part. As such, unless specified, the presence of cross-hatching or shading in no way supercedes, or otherwise clarifies, any aspect of the parts described as being clear, transparent, opaque, solid, formed, unformed, etc. Moreover, in the drawings, the size and relative sizes of parts can be exaggerated for clarity. When exemplary embodiments can be carried out in different ways, the specific sequential order described can be performed in a different order. For example, two sequentially described processes can be performed at the same time or in reverse order. Also, similar reference numerals denote similar parts throughout the description.

[0111] When a part is referred to as being "on" or "on top of" another part, "connected to" or "coupled to" another part, it can be directly on, directly connected to, or directly coupled to the other part, or intervening parts can be present. In contrast, when an part is referred to as being "directly on", "directly connected to", or "directly coupled to" another part, there are no intervening parts. In this regard, the term "connected" can refer to physical or electrical connection, with or without intervening parts.

[0112] For descriptive purposes, the disclosure can use spatial or relative terms, such as "below", "lower", "lowermost", "above", "upper" and "uppermost", "vertical", "horizontal", and the like, which are sometimes used for the purpose of explanation only. Such spatial and / or relative terms can encompass different positions and orientations of the device in use, operation, and / or manufacture. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. Moreover, the device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0113] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, to the extent that the terms "including," "includes," "having," "has," "with," or variants thereof are used in either the detailed description or the claims, such terms are intended to be inclusive in a manner similar to the term "comprising." It is also to be noted that the term "substantially" and other similar terms are used herein to refer to the inherent deviation in measured, calculated, and / or provided values that would be recognized by those of ordinary skill in the art as being within the scope of a reasonable amount of deviation of the stated values, such as within experimental error or within a reasonable range of values.
