Description

The automated cleaning filter of dust catcher
Technical field
The invention belongs to the dust catcher field, be specifically related to a kind of can effectively preventing owing to fore filter is stopped up the automated cleaning filter that causes the not smooth dust catcher of air-flow by dust.
Background technology
Dust catcher is a kind of household electrical appliance of indoor cleaning health, is used for removing the dust in ground, carpet, wall, furniture, clothing and various slits.In general; Dust catcher 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 through 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 that dust catcher is inner discharges, and forms instantaneous vacuum in the inside of 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 through air entry together with air.The air that contains dust after filtering, is discharged to the dust catcher outside again from the gas outlet in the dust bucket of body.Like this, just reach the effect of dust out, clean floor.The suction rate of dust catcher is divided into a plurality of retainings that control, and adapts to the scope of operation of different cleaning objects such as ground, bed surface, carpet, sofa, corner, so that aspirate dust everywhere better.
Profile classification according to dust catcher can be divided into vertical type dust collector, horizontal dust collector and portable dust collector etc.For dust catcher; No matter be vertical type dust collector or horizontal dust collector or portable dust collector; All be provided with the dust collect plant of assembling dust and foreign matter at inner of dust catcher body, inner dust of assembling of dust collect plant and foreign matter need regularly to remove, to guarantee the normal use of dust catcher.
Fig. 1 is the three-dimensional structure diagram of the cleaner dust collecting device of prior art; Fig. 2 is the profile of the cleaner dust collecting device of prior art, and Fig. 3 is the three-dimensional structure diagram of the filter cartridge of prior art.To shown in Figure 3, the dust collect plant of existing dust catcher comprises that dust bucket 2, cyclone separator 1, level are installed in the inner filter 3 of cyclone separator staving and the filter cartridge 4 of the fore filter that is connected with cyclone separator like Fig. 1; Be provided with in the filter cartridge 4 and filter sponge.The bottom of dust bucket is provided with the air inlet 5 that is connected with the bucket wall leading section of cyclone separator staving; The rearward end of the bottom bucket wall of cyclone separator staving is provided with dust outlet 6; Filter cartridge is provided with dust air outlet 7 corresponding to the filter opening part.
During the work of dust catcher sucktion fan; Near the suction nozzle dust together with air through air intake duct and in air inlet is drawn into cyclone separator; In cyclone separator, form swirling eddy, dust is in dust outlet drops to the dust bucket of bottom, behind the air of the inspiration simultaneously process filter separating and filtering in the process of air-flow rotation; Get into fan-electric motor units through fore filter, discharge by air outlet again.
The dust catcher of prior art uses of a specified duration, and the filtration sponge in the fore filter can adhere to a lot of dusts, blocks fore filter, causes airflow not smooth, and suction descends.At this moment, need filter cartridge is opened, the filtration sponge of inside is taken out, clean.But most of client thinks that the filtration sponge is taken out cleaning to bother very much, even some client is unwilling to start because the suspicion filtering material is too dirty to clean.Like this, in the course of time, not only the suction of dust catcher descends, and can damage motor.Therefore, the dust collect plant filter cleans problem difficult, inner dust easy blocking and presses for solution.
Summary of the invention
The present invention provides a kind of automated cleaning filter that can effectively prevent to be caused by the dust obstruction owing to fore filter the not smooth dust catcher of air-flow for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
The automated cleaning filter of dust catcher of the present invention comprises the filter cartridge that is connected with the cyclone separator of dust collect plant and is arranged on the filtering material in the filter cartridge; The side that filter cartridge is connected with cyclone separator is formed with the dust air outlet relative with the filter opening, and the box body bottom relative with the dust air outlet is formed with exhaust outlet.Filtering material in the filter cartridge is rugosity, is provided with oscillating plate between filtering material and the box body bottom, and the oscillating plate upside is connected with filtering material, and downside is connected with box portion bottom wall through spring.
Described filtering material is rugosity along the filter cartridge length direction, the cross section indention of filtering material.
Described filtering material is rugosity along the filter cartridge width, the vertical section indention of filtering material.
The downward tip of described filtering material all is connected with oscillating plate, and oscillating plate and filtering material junction form the vibrator bar post that upwards arches upward.
It is half-cylindrical that described vibrator bar post is.
Be provided with spring between described vibrator bar post and the box portion bottom wall, the upper end of spring is fixed on the place, summit that the vibrator bar post arches upward, and the lower end is fixed on the box portion bottom wall.
Be formed with air channel between the adjacent vibrator bar post on the described oscillating plate.
Be provided with screen pack between described oscillating plate and the box portion bottom wall.
Advantage and good effect that the present invention has are:
Automated cleaning filter of the present invention is arranged to rugosity with filtering material, and between filtering material is bottom the filter cartridge box body, the oscillating plate that is connected spring is set.When dust catcher carries out dust suction work, the spring under suction condition below the oscillating plate compression, when stopping dust suction work, the elastic potential energy that spring gathers makes spring flexible repeatedly, till energy has consumed.Oscillating plate drives the filtering material vibration under the effect of spring, play the effect of dust on the clean filtering material, thereby effectively prevents to cause air-flow not smooth owing to fore filter is stopped up by dust, improves the separative efficiency of dust catcher.
