Description

Brush

Technical field:

The utility model relates to a kind of brush that can effectively collect smooth body surface dust, and can be used for erasing the board, wipe the desk desktop, and the surface that cleans the windows.

Background technology:

The grey blackboard eraser of a kind of bundle is disclosed in the patent No. is 022953744 utility model patent specification, in the brushing both sides that are ordinary blackboard eraser flexible brush roll is set, find in actual use, owing to brandish very fast, though at the brushing two ends because of brandishing the formation air-flow, the dust of carrying secretly is collected, but the air-flow of wiping that also can produce up and down causes flying upward of dust.Simultaneously, when brushing itself was wiped ash repeatedly, a part of dust was the powder ball shape, powder ball or and can not get collecting because of himself gravity directly falls, or remain on the brush body, cause the surface cleanliness of being wiped poor.

Summary of the invention:

The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of do not have dust from flying, collecting effect good, clean the good brush of degree.

The technical scheme that the utility model technical solution problem is adopted is:

Design feature of the present utility model is parallel and is provided with at interval two and wipes rollers that the surface of wiping roller is a flexible cladding, has the bristle that tilts towards a direction on the described flexible cladding, two wipe bristle on the roller towards on the contrary; Ash-collecting cover is set, and described ash-collecting cover is wiped roller corresponding to two and is had from the grey passage of each independently axial collection, and the tail ends of two grey passages of collection are communicated with end ash drawer, in the grey passage of described collection, are provided with vertically and scrape hawk.

Design feature of the present utility model also is:

Bristle is all towards the inboard on described two wiping rollers.

Every collects the hawk of scraping that is provided with in the grey passage twice is arranged.

Above the grey passage of described collection, be provided with the containing cavity of lid.

Around described wiping roller, dust block board is set, wipe roller for two and only protrude from the dust block board plane separately with its wiping surface.

Compared with the prior art, the beneficial effects of the utility model are embodied in does not have dust from flying in the wiping process, collecting effect is good, it is good to clean degree.

Description of drawings:

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A generalized section of Fig. 1.

Fig. 3 is the utility model collection ash channel design schematic diagram.

Number in the figure: 1 wiping roller, 2 bristles, the grey passage of 3 collection, 4 grey drawers, 5 are scraped hawk, 6 lids, 7 storage chambers, 8 dust block boards.

Below the utility model is described in further detail by the specific embodiment:

Referring to Fig. 1, Fig. 2 and Fig. 3, parallel and be provided with at interval two and wipe rollers 1 in the present embodiment, the surface of wiping roller 1 is a flexible cladding, have on the flexible cladding 2, two of bristles that tilt towards a direction wipe bristle on the roller 1 towards on the contrary; Ash-collecting cover is set, and ash-collecting cover is communicated with end ash drawer 4 corresponding to the tail end that two wiping rollers 1 have from 3, two grey passages 3 of collection of the grey passage of each independently axial collection, and in collecting grey passage 3, hawk 5 is scraped in setting vertically.

In concrete the enforcement, as shown in Figure 1, bristle is promptly wiped between the roller towards two all towards the inboard on two wiping rollers.

Every the hawk 5 of scraping that collects setting in the grey passage 3 has twice, scrapes hawk 5 and adopts elastic materials.

As Fig. 2, shown in Figure 3, above the grey passage 3 of collection, be provided with the storage chamber 7 of lid 6.

In addition, can 8, two of dust block boards be set wipe roller 1 only protrudes from dust block board 8 separately with its wiping surface plane around wiping roller 1, the side wiping roller 1 place is provided with the brush bottom, so that protect bristle no the time, and is convenient to deposit or carry.

During use, with brush need on the plane of wiping along with wipe the vertical direction wiping back and forth of roll axis since two wipe bristle on the rollers towards on the contrary, in coming and going back and forth, always wipe roller for rolling for one, and another is wiped the stop translation of roller because of scraper plate.In the present embodiment,, therefore, in the process that brush moves, wipe roller for rolling, wipe the moving translation that is for back one in face of last of its moving direction because two wiped on the rollers bristle all towards the inboard.The dust that the wiping roller that rolls at first will be wiped on the plane is involved in the ash collecting box, and under the effect of scraper plate dust is trapped in the grey passage of collection, and the wiping roller of another translation further will be wiped the plane wiped clean subsequently.

In the wiping process for perpendiculars such as blackboards, because the grey passage of collection is vertically, dust directly falls into the grey drawer that is arranged in the bottom.

Carrying out for horizontal plane in the process of wiping, dust at first combines in the grey passage, finishes after the wiping, with brush then be vertically, rocks brush slightly, and dust falls into grey drawer equally smoothly, in order to using next time again.

When using, can be used for placing chalk in the storage chamber 7 as blackboard eraser.
