Abstract
The invention discloses a brush head of a dust collector, which comprises an upper cover, a bottom shell and a connecting pipe; the brush head of the dust collector is formed by combining the bottom shell and the upper cover, and the upper cover part is protruded, so that a larger dust-absorbing space is formed inside, a telescopic dust-absorbing pipe connecting pipe which is communicated with the inside of the shell is arranged at the center, and the brush head is arranged on the bottom surface of the bottom shell; a notch is drilled at the front ends of the upper cover and the bottom shell, a fan is arranged in the notch, and a baffle plate is arranged at the upper end of the notch. The invention has the advantages that because the notch is arranged at the front end of the brush head of the dust collector, and the cylindrical fan is arranged in the notch thereof, a gap is formed between an absorption inlet and the ground, thereby larger granules are ensured to be successfully absorbed, and meanwhile, because the cylindrical fan is driven by an airflow to rotate at high speed, the adsorption range of the brush head of the dust collector is enlarged, and the adsorption efficiency of the dust collector is improved.
Description
Technical field
The present invention relates to a kind of dust catcher; Particularly relate to a kind of brush head of dust collector that can efficiently adsorb dust granule.
Background technology
Usually, vacuum cleaner is to utilize vacuum to produce suction to suck air, makes air flow through various filters, airborne foreign matter is filtered the device in the cleaning chamber.
In general, vacuum cleaner mainly comprises aspirator and suction line, with motor and blower fan is that the aspirator that dominant shape becomes is arranged in the body, suction line comprises suction nozzle and air intake duct, and the air entry of the oriented under shed of suction nozzle and telescoping tube and flexible pipe by air intake duct communicate with the air inlet of body inner blower.During the dust catcher running, the impeller of motor drives blower fan rotates at a high speed, and the air in the dust catcher is discharged, and forms instantaneous vacuum in dust catcher, and forms a quite high Negative Pressure Difference between the ambient atmosphere.Under the effect of this Negative Pressure Difference, near the dust the suction nozzle sucks in the dust bucket in the body by air entry together with air.The air that contains dust after filtering, flows back to the dust catcher outside from air outlet again in the body dust bucket.Like this, just reach the effect of dust out, clean floor.The suction rate of vacuum cleaner is divided into a plurality of class of operating control, adapts to the scope of operation of different cleaning objects such as ground, bed surface, sofa, corner, so that aspirate dust everywhere better.
Press the use and the moving method of vacuum cleaner, can be divided into horizontally, vertical, portable etc., little foreign matters such as dust clean: ground such as vertical easy cleaning woollen blanket with comparalive ease in the wherein horizontal family that is mainly used in; The portable narrow positions such as step, desktop of easily cleaning.
In addition, vacuum cleaner can be divided into filer element type, cyclone type to the mode that foreign matters such as dust, hair filter by it.Wherein filer element type makes the air that contains foreign matter flow through a kind of dry goods dust bag, foreign matter filtered to change dust bag periodically, and cyclone type makes the suction air generation swirling flow that contains foreign matter, fall the bottom surface with sucking the deadweight effect tenesmus of airborne foreign matter in rotary course, do not need dust bag, its use amount just constantly rises.
Dust catcher is for adapting to the cleaning in different cleaning face or corner, and common brush head of dust collector can have difformity and purposes, as tapered suction nozzle, and selective uses such as the brush head of dust collector of rectangle.
It is integrally formed that common dust catcher conical shell connects adapter, the conical shell Duanxi inkstone is provided with suction nozzle, its inside is formed with air intake duct, make its inside be formed with bigger dust suction space, and in a side and the logical sweep-up pipe adapter of air intake trough rim, during use, dust sucting motor work behind the importing electric current, dust on the cleaning face enters in the suction head of suction cleaner through the suction nozzle of conical shell end face, and through air intake duct, sweep-up pipe adapter, hose, the device of passing by on one's way enter the dust collecting part of gathering suction.
Fig. 1 is the structural representation of the brush head of dust collector of prior art.As shown in Figure 1, brush head of dust collector is by rectangle drain pan 1 and loam cake 2 be combined intos, and loam cake 2 tops are outstanding, make and form big slightly dust suction space in it, and in central authorities be provided with shell in the expansion sweep-up pipe that is communicated with take over 3, the bottom surface of drain pan 1 is provided with brush.During use, dust sucting motor (not shown) work behind the importing electric current, dust on the cleaning face enters in the brush head of dust collector through the suction nozzle of drain pan 1 bottom surface, enters the dust collecting part (not shown) of gathering inhalation (inhalatio) through sweep-up pipe adapter 3, hose (not shown), filter (not shown).On drain pan 1 bottom surface and the air intake duct (not shown) that forms between the suction nozzle replenish inhaled air, be beneficial to the dust suction operation.When the brush front end of existing common dust catcher directly contacts with ground, when the place ahead runs into the bigger object of volume, need lift brush, otherwise brush can promote object to move ahead, cause the reduction of adsorption effect, when raising brush, can cause brush overhead far away again, fall to be bonded at ground minute dust particle and omit.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, and a kind of expansion adsorption range is provided, and improves adsorption efficiency, can suck the novel dust collector brush that molecule can suck big rubbish again.
The technical solution adopted in the present invention is: brush head of dust collector comprises loam cake, drain pan and adapter; Brush head of dust collector is by drain pan and loam cake be combined into, and upper cover part is outstanding, make and form big slightly dust suction space in it, and in central authorities be provided with shell in the expansion sweep-up pipe that is communicated with take over, the bottom surface of drain pan is provided with brush; The front end of described loam cake and drain pan has notch, is provided with fan in described notch, is provided with plate washer in the upper end of described notch.
Described fan is an aerofoil fan, and the two ends of the axle of its fan are connected with the notch both sides of loam cake respectively, and described fan can rotate freely.
Described fan shaft and fan are integrally formed.
Described plate washer is an arc, plane on the notch of covering loam cake.
Described fan and bottom surface are formed with the gap.
It is 3-5mm that described fan and bottom surface are formed with the gap.
The invention has the beneficial effects as follows: owing to be provided with notch at the front end of brush head of dust collector, and in its notch, be provided with the column fan, make suction inlet and ground be formed with the gap, guarantee that larger particles is sucked smoothly, owing to driving the column fan, rotates at a high speed in air-flow simultaneously, enlarge the adsorption range of brush head of dust collector, improved the adsorption efficiency of dust catcher.
