Abstract

The utility model relates to an electric vacuum cleaner which is composed of a dust filtration device and a motor. The dust cup of the dust filtration device is separated into two chambers by a rib; the upper chamber is a dust filtration chamber which is provided with a cyclone director and a filter; the lower dust chamber is a dust storage chamber; the rib between the upper chamber and the lower chamber is provided with a gap; the front end of the cyclone director is connected with an air inlet on the front end of the dust cup, and the back end of the cyclone director is connected with the filter; when air with dust passes through the cyclone director, the electric vacuum cleaner generates rotary air current causing the air current to tightly stick to the inner wall of the cylinder in the dust filtration chamber, and the electric vacuum cleaner proceeds towards the direction of the filter in a spiral type causing most dust in the air current to be thrown towards the dust storage chamber in the action of centrifugal force and gravity via the gap and little dust to be filtered via the filter. Compared with common suction cleaners, the electric vacuum cleaner is fine in dust filtration effect and convenient to clean; the service life of the filter is extended, and the electric vacuum cleaner is favorable for environmental protection; and the utility model is an ideal sanitary equipment which can be widely used in locations such as hotels, markets, office buildings, dwelling house, etc.

Description

A kind of electric cleaner

Technical field the utility model relates to dust catcher, particularly a kind of electric cleaner.

Background technology was not found identical electric cleaner as yet before the utility model is made.Electric cleaner on the market generally all is to filter dust by traditional cloth bag or paper bag now, also has by screen pack and filters dust.The screen pack of existing electric cleaner generally all is located at dust-storage chamber.Because the air process dust catcher air inlet that has dust just enters into the screen pack of dust-storage chamber, has strengthened the burden of screen pack like this, the screen pack so the dust that gathers is very easily made dirty then cleans to the user and also makes troubles, and shortened the service life of screen pack.

The summary of the invention the purpose of this utility model; provided a kind of dust before the process filter; overwhelming majority dust is thrown toward apotheca earlier; and the dust catcher that small amount of dust is filtered through filter again; this dust catcher can improve filter dirt effect; help environmental protection, make things convenient for the user to clean again, also prolong filter service life.

The purpose of this utility model is to realize by following technical scheme: the dirt cup in the dust filtration device is separated into upper and lower two chambers by a muscle, above a chamber be dust chamber, in be provided with whirlwind guider and filter, below a chamber be dust-storage chamber; Have breach on the muscle between dust chamber and the dust-storage chamber; Whirlwind guider front end is connected with dirt cup front end air inlet place, and the rear end is connected with filter; The whirlwind guider is made of cylindrical duct and the spiral vane that is looped around on the cylindrical duct.Owing to adopt technique scheme, obviously, dust is difficult for being adsorbed on the filter outer surface in this electric cleaner, thereby alleviated the burden of filter greatly, filter dirt is effective, cleaning more conveniently, and prolong filter service life, is a kind of desirable cleaning appliance that can be widely used in places such as hotel, airport, market, office building and dwelling house.

Description of drawings Fig. 1 is the utility model structure cutaway view;

Fig. 2 is the utility model vertical view;

Fig. 3 is the stereogram of whirlwind guider 3 shown in Figure 1.

The specific embodiment is further described the utility model in conjunction with the embodiments below by accompanying drawing: as Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises dust filtration device and 16 two parts of motor.Establish a muscle in the dirt cup 1 in the dust filtration device and separate into upper and lower two chambers 7,4, lower chambers is dust-storage chamber 4, be used to store dust rubbish; Upper chamber is a cylindrical shape dust chamber 7; Have a breach 5 on the muscle between dust chamber 7 and the dust-storage chamber 4; By cylindrical duct 24 be looped around the whirlwind guider 3 that the spiral vane 23 on the cylindrical duct 24 constitutes and be fixed on dust chamber 7 front portions, whirlwind guider 3 front ends are connected with dirt cup 1 front end air inlet place, and the rear end is connected with filter 6 air inlet place fore-stocks; Filter 6 air outlet place after-poppets are connected with lid 11 air inlet places; Sealing ring 12 front ends that are wrapped on the edge, lid 11 outer ring are connected with dirt cup 1 rear end, and the rear end is connected with left and

right casing

22,17 front ends, and sealing ring 12 is used to seal dirt cup 1 and left and

right casing

22,17; Dirt cup 1 top is provided with leader 8, and handle 8 is provided with latch hook 9 and lock hook seat 10 with dirt cup 1 junction; The trundle 2 that dirt cup 1 bottom is provided with can make this dust catcher advance or rotate; In addition, be located at left and

right casing

22,17 outsides big roller 21 can with trundle 2 use of working in coordination.Motor 16 is fixed in the left and

right casing

22,17 by motor locating piece 18; Be provided with filter 13 between lid 11 and the motor 16; Be provided with sealing ring 15 between motor 16 front portions and the left and

right casing

22,17 and be used for sealed electric-motor 16; Left and

right casing

22,17 rear ends of motor 16 afterbody back are provided with filter 19, air-out screen 20 successively, and the top is provided with switch 14.Dirt cup 1 of the present utility model, handle 8, whirlwind guider 3 and left and

right casing

22,17 all adopt duroplasts to make; Wherein dirt cup 1 also can adopt transparent hard plastic to make, and like this, the user can observe dust reserves situation in the dust-storage chamber 4 at any time when using dust catcher, so that in time remove the dust in the dust-storage chamber 4, simultaneously, can also dynamically appreciate dust removal process.Filter 6 adopts high efficiency particulate air (HEPA) and plastic stent to constitute.Motor 16 adopts the series excitation type asynchronous machine.

The practicality simple to operate of this electric cleaner, only with hand is pressed latch hook 9, and this dust catcher just is divided into dust filtration device and motor 16 front and back two parts.Dust filtration device is easy to mounting or dismounting, helps removing rubbish.The user firmly outwards pulls out lid 11, and this device just is divided into two parts, and the rear section comprises lid 11, sealing ring 12, filter 6; And forward part dirt cup 1 is independent part, include the guider 3 that produces whirlwind in this dirt cup 1, handle 8 on dirt cup 1 top, be used for arresting single dirt cup 1, promptly arrest whole dust filtration device, like this, make things convenient for the user to remove the dust rubbish in the dust-storage chamber 4 and residued in thin dirt in the dust chamber 7.

Operation principle of the present utility model is: when switch 14 closures, it is power connection, motor 16 enters the high speed rotating operation, form vacuum like this in the dust catcher, be in negative pressure state, make the air that has dust enter dust chamber 7 from dirt cup 1 front end air inlet, during through whirlwind guider 3, produce swirling eddy, make air-flow at the inwall of these chamber 7 cylinders of dust chamber's 7 inner close fittings, to filter 6 directions in the shape of a spiral formula advance; Therefore along with spiral dust in air of advancing under the effect of centrifugal force and gravity, wherein most dusts are thrown toward dust-storage chamber 4 during breach 5 on by an above-mentioned muscle, and the air of band small amount of dust passes through filter 6 and filter 13 and filter 19 successively again by multiple times of filtration, at last, the air that comes out from air-out screen 20 is comparatively clean air, has also played environmental-protection function.
