Description

Brush roller component for wet type floor wiping machine

Technical Field

The utility model relates to the technical field of cleaning equipment, in particular to a brush roller assembly for a wet type floor wiping machine.

Background

The wet scrubbing device enables the surface to be cleaned by means of a rotating brush roller wetted with a liquid. Prior art brush rolls for wet-scrubbing devices are usually made of a soft, fine-fiber material which can be wetted with a liquid, so that a wet-scrubbing of the floor surface by means of the liquid is achieved. Due to the limited frictional properties of fine fiber materials, they can only wipe common stains on the ground, while cleaning ability is limited when they encounter stubborn stains adhering to the ground.

In order to improve the cleaning ability of such a brush roller, chinese patent publication No. CN109938647A discloses a brush roller in which a wiping surface made of a fine fiber material is planted with a plurality of clusters of hard bristles, and in the contact process of the brush roller with the ground to be cleaned, the friction force between the hard bristles and the ground is much greater than that between the fine fiber material and the ground, so that the brush roller can easily realize the treatment of stubborn stains on the ground to be cleaned.

However, when the brush roller is manufactured, a plurality of hard bristles on the brush roller need to be planted in a cluster independently, so that the manufacturing process is time-consuming and labor-consuming, the manufacturing cost is high, and the cost control of the brush roller is not facilitated.

Detailed Description

To explain technical contents, structural features, achieved objects and effects of the present invention in detail, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a detailed description of various exemplary embodiments or implementations of the utility model. However, various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. Moreover, the various exemplary embodiments may be different, but are not necessarily exclusive. For example, the particular shapes, configurations and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

Referring to fig. 1-2, the brush roller assembly 100 can be used in a wet scrubber, such as a vertical stick type, a portable type, a self-moving type, etc., and can be used to roll up or adhere dirt on the floor by contacting the bottom opening of the scrubber with the floor, and then suck garbage into the sweeping robot by negative pressure to complete dust collection. The brush roller assembly 100 of this example is comprised of a central body 1, a left connector 2, a right connector 3, and a bristle member 4.

The central body 1 is located in the middle and is cylindrical; the central body 1 is of hollow construction and has a left end 11, a right end 12 and a peripheral side wall 13 extending between the left and right ends 11, 12. The central body 1 may be an injection moulded integral part; in other embodiments, the central body may be assembled from multiple injection molded components.

Left connector 2 and right connector 3 arrange respectively in left side end 11 and right side end 12 positions department, specifically do: the left connector 2 is fixed at the left end 11 and is capable of plugging the left end 11 of the central body 1. The left connecting head 2 is an assembly having a bracket 21, a bearing 22 mounted on the left end 11, and a connecting shaft 23 supported on the bearing 22 and fixed to the bracket 21. The right connector 3 is fixed at the right end 12 and is capable of plugging the right end 12 of the central body 1. When the brush roller assembly 100 is fixed to the corresponding part of the wet scrubber, the bracket 21 of the left connector 2 will be fixed with the corresponding part of the wet scrubber; the right connector 3 will be coupled to a corresponding drive mechanism of the wet scrubber to effect rotation of the central body 1 driven by the drive mechanism.

The bristle part 4 extends between a left end 111 and a right end 12 and is fixedly covered on the peripheral side wall 13. In this example, the bristle part 4 is an integral component and has a fabric layer 41, and the fabric layer 41 includes hard wool strips 411 in a spiral shape and soft water-absorbent fluff 412 filled between the hard wool strips 411 in a spiral shape. The bristle member 4 is adhesively secured to the peripheral side wall 13.

In the embodiment shown in FIG. 3, the radial height H1 of the hard bristles 411 is greater than the radial height H2 of the soft water-absorbing fluff 412, i.e., the hard bristles 411 protrude radially outward beyond the soft water-absorbing fluff 412. In other schemes, the radial height of the hard wool top can be lower than or equal to the radial height of the soft water absorption fluff; in a preferable scheme, the difference between the radial height of the hard wool top and the radial height of the soft water absorption fluff is selected to be within +/-2 mm. For example: the radial height of the hard wool top 411 is 5-20mm, and the radial height of the soft water absorption fluff 412 is 5-20 mm. The hard wool top 411 can be selected from nylon bristles with the diameter of 0.1-0.3mm, and the soft water-absorbing fluff 412 is composed of polyurethane fluff. After the brush hair piece actually contacts the ground, because the soft water-absorbing fluff is easy to collapse after absorbing liquid, the actual interference magnitude between the soft water-absorbing fluff and the ground is smaller than that between the hard wool top and the ground.

As shown in fig. 4, the woven cloth 4 'having a long strip shape is formed by spirally winding the woven cloth 4' around the outer peripheral side wall 13. The hard top 411 is positioned on the pair of long sides 41 'of the woven fabric 4', and the soft water-absorbent piles 412 are distributed between the pair of long sides 41 'of the woven fabric 4'.

The brush roller assembly 100 of this example may be adapted for use on hard and soft surfaces, and the fluid wetting the brush roller assembly may be water, or an aqueous solution with added cleaning agents, disinfectants, etc.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the foregoing description only for the purpose of illustrating the principles of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims, specification, and equivalents thereof.
