Description
Technical field
The present invention relates to the dust removal with machine technical field, particularly relate to a kind of vacuum cleaner.
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.
As shown in Figures 1 and 2, existing a kind of vacuum cleaner comprises the dust bag 11 of collecting the foreign matter that sucks substantially: the body of dust collector 10 that produce and suck air-flow, sucks above-mentioned foreign matter; Be connected the suction inlet 20 of above-mentioned body of dust collector 10, air and various foreign matter in the suction chamber.
At this moment, above-mentioned suction air-flow production part comprises fan 13 and motor 12, is connected with suction hose 31, handgrip 32 and extension pipe 33 between above-mentioned suction inlet 20 and the above-mentioned body of dust collector 10 in turn.
In addition, have exhaust outlet 14 under the rear side of above-mentioned body of dust collector 10, it is to the outside air of discharging through dust bag 11 of dust catcher, and above-mentioned exhaust outlet 14 has discharge filter 15.
Above-mentioned motor 12 sucks extraneous air and various foreign matters by suction inlet 20 after driving rotary fan 13 generation suction air-flows.Above-mentioned inhaled air and various foreign matter are successively by entering the dust bag 11 of body interior behind extension pipe 33, handgrip 32, the suction hose 31.
As mentioned above, said external air and various foreign matter are by in the process of dust bag 11, above-mentioned various dust is collected in the dust bag 11, and the air that contains fine dust flows into the lining, space (space that promptly comprises motor 12 and rotary fan 13) that sucks the air-flow production part is set.Air is discharged to body of dust collector 10 outsides by exhaust outlet 14.The said external air is by in the process of exhaust outlet 14, and the dust that above-mentioned inside air is fine hangs on the discharge filter 15 that is arranged on above-mentioned exhaust outlet, the environment of dust catcher outside is polluted avoiding, thereby reduces the reliability of dust catcher.
Above-mentioned vacuum cleaner can move to the each place according to user's demand and clean.This is to finish by the roller 16 that can be installed in body of dust collector 10 two sides rotatably.
But, in view of extraneous air sucks from suction inlet 20, after entering into dust bag 11, various foreign matters and bigger dust have been collected in the dust bag 11, the air that contains fine dust then flows into the lining, space (space that promptly comprises motor 12 and rotary fan 13) that sucks the air-flow production part is set, most of air is with the straight line beeline motor 12 of flowing through, be discharged to the outside of body of dust collector 10 then by exhaust outlet 14, because motor 12 can produce heat when work, thereby feasible air by exhaust outlet 14 is a thermal air current, thermal air current directly passes through exhaust outlet 14 with the straight line beeline behind the motor of flowing through, and air quantity is bigger, the discharge filter 15 that exhaust outlet 14 places are set is under the effect of long-time thermal air current, cause this discharge filter 14 temperature distortions easily, cause between discharge filter 14 and the exhaust outlet mouth 14 and can't closely connect, there is certain slit each other, the air that contains fine dust lets out from the slit, environment to the dust catcher outside pollutes, and badly influences the pick-up performance of dust catcher.In addition, discharge filter 14 temperature distortions make discharge filter 14 be not easy to dismantle, and the user is difficult in maintenance.
