Abstract

The utility model discloses a dust collector floor brush with an automatic hair cutting structure. The dust collector floor brush comprises a base, a rolling brush, a tool rest, a blade and a torsion spring, wherein the base is provided with a rolling brush chamber; the rolling brush is arranged in the rolling brush chamber, and is provided with a plurality of bristles; the tool rest is fixedly arranged on the base, and extends towards the rolling brush chamber; the blade is at least partially accommodated in the tool rest; and the torsion spring is arranged between the base and the tool rest and enables the tool rest to rotate relative to the base. According to the dust collector floor brush, garbage such as hair or long paper slips can be automatically cut to prevent the rolling brush from locked rotation, the cleaning efficiency is improved, and the labor intensity of a user is reduced.

Description

A kind of have cut the floor brush of dust collector of sending out structure automatically

Technical field

The utility model relates to a kind of floor brush of dust collector of cutting a structure automatically that has.

Background technology

Existing floor brush of dust collector often comes ground is cleaned by round brush, and rubbish such as hair or long paper slip are often arranged on the ground, be easy to be wrapped on the round brush, thus the resistance of increasing round brush, even cause the round brush stall, influence the user and use.

The utility model content

The utility model purpose is: a kind of floor brush of dust collector of cutting a structure automatically that has is provided, to cut off rubbish such as hair or long paper slip, improves cleaning efficiency.

The technical solution of the utility model is: a kind of have cut the floor brush of dust collector of sending out structure automatically, it comprises base with round brush chamber, be arranged on round brush indoor and have several bristles round brush, be fixed on the base and the knife rest that extends towards the round brush chamber, at least part ofly be housed in blade in the knife rest, be arranged between base and the knife rest and guarantee the torsion spring of the relative base rotation of knife rest.

On the basis of technique scheme, further comprise following attached technical scheme:

It further comprises several fixtures that pass knife rest and blade respectively and blade and knife rest are interfixed.

Described fixture is rivet or screw.

Described knife rest comprises that the shaft, the part that are set in the torsion spring are contained in the accepting groove of blade and communicates with accepting groove and receive several knife rest holes of fixture.

Described blade comprises the cutting portion that part is contained in the base portion in the accepting groove and is formed by the terminal bending of base portion, and wherein base portion has several fixing holes with knife rest hole corresponding align.

The angle that described cutting portion and base portion intersect is the obtuse angle, and contacts with bristle.

The utility model advantage is:

The utility model can cut off rubbish such as hair or long paper slip automatically, prevents the round brush stall, improves cleaning efficiency, reduces user's labour intensity.

The specific embodiment

Embodiment: shown in Fig. 1-5, the utility model provides a kind of specific embodiment of cutting the floor brush of dust collector of sending out structure automatically that has, and it comprises the base 10 with round brush chamber 12, be arranged in the round brush chamber 12 and the round brush 20 of several bristles 22 is arranged, be fixed on the base 10 and 12 knife rests 30 that extend towards the round brush chamber, at least part of blade 40 that is housed in the knife rest 30, several fixtures 50 that pass knife rest 30 and blade 40 respectively and blade 40 and knife rest 30 are interfixed, be arranged between base 10 and the knife rest 30 and guarantee the torsion spring 60 of relative bases 10 rotations of knife rest 30.

Knife rest 30 comprises that the shaft 32, the part that are set in the torsion spring 60 are contained in the accepting groove 34 of blade 40 and communicates with accepting groove 34 and receive several knife rest holes 36 of fixture 50.

Blade 40 comprises the cutting portions 44 that part is contained in the base portion 42 in the accepting groove 34 and is formed by base portion 42 terminal bendings, and wherein base portion 42 has several fixing holes 420 with knife rest hole 36 corresponding align.Cutting portion 44 is the obtuse angle with the angle that base portion 42 intersects, and contacts with bristle 22.Fixture 50 is preferably rivet or screw.

When initial, cutting portion 44 contacts with bristle 22, and base portion 42 does not contact with bristle 22, during work, the user presses down a power, makes knife rest 30 relative bases 10 around axle deflection and 60 deformation of compressing torsion spring, and allow the axe movement of cutting portion 44 towards round brush 20, make base portion 42 beginning contact with bristle 22, owing to round brush rotates at a high speed, cutting portion 44 self is comparatively sharp, be easy to rubbish such as hair or long paper slip are cut off, stop the winding of such rubbish, reduce the resistance of round brush, guarantee working properly.When the user cancelled power, torsion spring 60 recovered deformation, impels knife rest 30 to get back to original position.

Certainly above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.The all spiritual essence of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
