Description

Brush head of dust collector with wind rotor

Technical field

The present invention relates to drive the brush head of dust collector of the loose instrument of dust, specifically is a kind of brush head of dust collector with wind rotor.

Background technology

Dust catcher is a kind of sanitation and hygiene electrical installation, is used for removing the dust in ground, carpet, wall, furniture, clothing and various slits.

Profile classification according to dust catcher can be divided into vertical type dust collector, horizontal (pot type) dust catcher and portable dust collector etc.

Dust catcher comprises substantially and imports the motor of dust collector that electric current generates suction, forms the motor air inlet of air path system, suction nozzle (suction nozzle), and hose filters and gathers the dust collect plant etc. of inhalation (inhalatio).

For adapting to the dust suction operation of different cleaning face, the brush of dust catcher can have difformity structure and uses thereof, like tapered pointed suction nozzle; The type of twitching one's mouth slit suction nozzle; The square suction nozzle brush of band roller, and the suction nozzle of planting bristle on the roller supply being installed on the rigidity dust suction bar of user selection to use.

Chinese patent 1879540 discloses a kind of " dust catcher has the brush of rotating brushes ", comprises that the drain pan 2a of front truckle 16, rear truckle 15 is arranged at the bottom; The loam cake 1a that is connected with drain pan 2a; In the cavity of drain pan 2a and loam cake 1a, impeller 5 is equipped with in the place ahead of insertion pipe 4; Loam cake 1a is outstanding in the middle of being, both sides are the housing of arc surface; On the impeller shaft 6 that in cavity, has fixed support 17 to support impeller 5 is housed; Driving belt 18 also is housed on the impeller shaft 6; Driving belt 18 other ends are connected with the driven shaft 19 that taper pinion 24 respectively is equipped with at two ends; Driven shaft 19 is by pedestal 20 supportings, and pedestal 20 bottoms are the ∏ shape of both ends open, form annular seal space between ∏ shape and drain pan 2a; There is a steam vent centre of annular seal space, and taper pinion 24 meshes with two a tapers gear wheel 23 respectively; The rotating brushes (not shown) that is integrally formed with it is arranged at each taper gear wheel 23 bottom.Advantage: because hairbrush rotates, the contact-making surface of bristle and ground or cleaning face increases, and frictional force is big, the friction number of times increases, and is prone to make the dust hard scale loose, therefore cleans effective.Dust catcher is applied widely in addition.

Fig. 1 is the stereogram of prior art brush head of dust collector, and Fig. 2 is the internal structure sketch map of prior art brush head of dust collector.As shown in the figure, brush head of dust collector comprises rectangle drain pan 2a and the loam cake 1a that is connected with drain pan 2a; Outstanding in the middle of the loam cake 1a is approximate trapezoid, and both sides are the housing of arc surface.

In the cavity of brush head of dust collector drain pan 2a and loam cake 1a formation, the fixed support 17 that is fixed on the drain pan 2a is equipped with in the place ahead of insertion pipe 4, is used to support the impeller 5 on the impeller shaft 6; Driving belt 18 also is housed on the impeller shaft 6; Driving belt 18 drives the taper pinion 24 at driven shaft 19 two ends; Taper pinion 24 meshes with two taper gear wheels 23 respectively, and each taper gear wheel 23 bottom surface is provided with the rotating brushes (not shown) that is integrally formed with it.

Rotating brushes (not shown) is made up of brush holder that is integrally formed with taper gear wheel 23 and several pinches of bristles that are formed on the brush holder.The thin disk that is I-shaped hollow is arranged at brush holder top, in the top insertion taper gear wheel 23 of thin disk, is injection molded into one with taper gear wheel 23; Be provided with disk below, the disk bottom surface has the bristle hole of several implantation bristles of circular distribution.

The brush head of dust collector of prior art drives 24 transmissions of taper pinion through impeller shaft 6, driving belt 18 successively; Make taper gear wheel 23 rotations that are 45 ° of engagements with taper pinion 24, thereby make integrally formed rotating brushes (not shown) realize pneumatic actuation rag disk wiping ground.But in order to guarantee that the rag disk covers the bottom of whole brush, need taper gear wheel 23 be designed to bigger size, though improved gearratio like this; But reduce the rotating speed of rag disk; Cause cleaning effect not good, and because belt transmission structure cause efficient not high.

Summary of the invention

The present invention is exactly when solving the dust suction operation, because belt transmission structure causes the gear wheel operating efficiency not high, rotary speed is slow, the problem that cleaning effect is not good enough, and a kind of brush head of dust collector with wind rotor is provided.

The present invention realizes by following technical scheme.

A kind of brush head of dust collector with wind rotor; Comprise loam cake; The drain pan bottom surface that is communicated with insertion pipe is formed with suction port; Be provided with impeller and the gear that is connected the rag disk in the drain pan, thereby establish the inlet channel of impeller in being formed with between suction port and the insertion pipe, the inlet channel outside is provided with the pinion with the same impeller shaft of impeller; Be provided with the gear wheel of engagement along the pinion center line both sides correspondence of drain pan length direction, be arranged in the disk groove of drain pan bottom surface with the rag disk of gear wheel respectively with gear shaft.

The present invention of design has omitted the bel-drivenn structure like this, makes overall structure simpler, and efficient is higher, has guaranteed that gear wheel has bigger torque, and the rotating speed of circular rag is faster, clean effectively, and the gearratio of big pinion reduces realization easily.
