Abstract

The utility model discloses a multipurpose miniature duster with a blowing function, which mainly comprises a blower, a blower casing and a hollow handle with a battery cavity and a dust collection cavity. The multipurpose miniature duster with a blowing function integrates the functions of dust suction, dust blowing and dust collection, and has the advantages of simple structure, small size and convenient use. The multipurpose miniature duster with a blowing function is an ideal tool for dust cleaning of precise instruments or optics mirror surfaces.

Description

Multipurpose miniature duster with blowing function

The utility model relates to a kind of dedusting instrument, particularly a kind of miniature suction dust blowers of using that are used to remove dust on precision instrument and the optical mirror plane more.

The present external like product relevant with the utility model, its structure is that straight pipe type is split type, promptly need install disposal box and work bend pipe when work additional, uses very inconvenient like this.Domestic still do not have like product at present, in the past the time to precision instrument or optical mirror plane dedusting, adopt the rubber ball air blast to carry out dedusting, this kind method has a lot of deficiencies in actual applications: at first air blast can only be with the dust displacement, and can not dust out, the dust that is blown afloat racks and floats in the air, and very fast landing nearby, causes secondary pollution with this; Secondly, be easy to produce static on some high insulation working substance surfaces, and the absorption affinity of dust is very strong during static, air blast is just powerless; In addition, in the dust suction chamber that rubber ball is easy to blow afloat in air blowing process, these dusts blow out once more to be beaten on the work object plane, causes " dying embers " probably, is difficult to remove, if enter moisture in the rubber ball chamber again.To endanger bigger to precision instrument, especially optical mirror plane.

The purpose of this utility model provides that a kind of volume is little, simple in structure, easy to use, collection suction, drifting dust, control of dust are the miniature many with inhaling dust blowers of one.

The purpose of this utility model is realized by following technical scheme: it comprises Blower Housing that the negative pressure centrifugal fan is housed and the hollow grip that links together with this housing, and Blower Housing is provided with control fan starting and the operating switch that stops.The front end of Blower Housing is provided with taper air suction opening and the function suction pipe that can be enclosed within on this taper air suction opening, and its technical essential is that the hollow grip inner route clapboard is divided into the upper and lower chamber of battery being installed and collecting dust.Wherein the cavity of resorption front portion is provided with a vent that is communicated with Blower Housing front end air suction opening, cavity of resorption front lower ends and cavity of resorption tail end are respectively equipped with the steam vent of drifting dust hole and band filter screen, are between the center line of Blower Housing and the hollow grip greater than 90 degree and less than the 180 work angles of spending.Be enclosed within function suction pipe on the taper air suction opening and select the suction pipe of different structure shape according to the dust on the different operating object plane that will remove for use.Having on the working substance in slit dust as removing selects for use duck to chew the shape suction pipe; Dust is selected oblate suction pipe for use on the working substance of removing plane; Dust is selected taper deep holes suction pipe for use on the interior working substance of removing deep holes; As " the dead dirt " removed on the work object plane selects the suction pipe of being with scrub-brush for use, the suction pipe of the dust employing band banister brush on the removing optical mirror plane.During dust suction one upper shield is enclosed within on the drifting dust hole, the switch that pushes the work forward is then connected the battery in centrifugal fan and the hollow grip, make the centrifugal fan rotation form negative pressure, band dirt air-flow is sucked by the taper air suction opening, in vent enters hollow grip cavity of resorption (dust-collecting cavity), the clean wind of low pressure behind strainer filtering is discharged from the steam vent of hollow grip cavity of resorption tail end, forms the circulation of air-flow with this.During drifting dust the steam vent of cavity of resorption tail end is sealed with a upper shield, the air-flow that sucks through air suction opening is discharged by drifting dust hole and the suction pipe that is enclosed within on the drifting dust hole, reaches the purpose that blows dust on the working substance off with this.

The utility model is owing to be integrated in one dust suction, drifting dust, dust collection function, and therefore simple in structure, it is comparatively convenient to use.

Detail of the present utility model is provided by following examples and accompanying drawing thereof:
