Abstract

The invention relates to a cyclone dust collector (21, 22) for a vacuum cleaner, comprising a dust collector (3) which can be removed separately from the cyclone dust collector (21, 22). The cyclone dust collector (21, 22) conventionally sets the dust from the dust-loaded air entering the cyclone dust collector (21, 22) via an air admission opening (23) rotating, thereby separating it into the dust collector (3). The dust-free air is transported via an air exit (29) to an external fine particulate air filter (9) and discharged into the surroundings via said filter. The invention is characterized in that the cyclone dust collector (21, 22) comprises an additional opening which is closed by a detachable cover (26) so that it can be easily cleaned when clogged.

Description

The whizzer that is used for dust catcher

The present invention relates to a kind of whizzer that is used for dust catcher as described in the preamble according to claim 1.

The what is called according to the centrifugal force mask work that has had various structures does not have a bag dust catcher.In the dust catcher of this version, dirt collecting receptacle and whizzer are constructed or are installed in combination in the public shell as a member.Whizzer for example is arranged in the inside of dirt collecting receptacle, and foul is outwards arranged in the container that surrounds separator.The major defect of this structure is, also whizzer must be taken off together when taking off dirt collecting receptacle for the emptying dust.Therefore the whole part that will take off is very heavy and inconvenient.This is external to carry out one of them member always also must revising another member simultaneously and doing further exploitation under the situation of further technological development.Need high development cost thus.

Owing to this reason has produced second type the dust catcher according to centrifugal principle work, they have the still coupled dirt collecting receptacle of separating with separator.Can only take off dirt collecting receptacle for emptying this moment.In this pattern, dirt collecting receptacle and whizzer are generally all constructed very simply.

With selected structure irrespectively, in this dust catcher with whizzer, owing to there are many members that are used for different entrance and exits, containing the air of dust or separated dust must carry and form thus narrow position by these entrance and exits, and therefore the incidence that gets clogged is always very high.

Therefore task of the present invention is a kind of whizzer that is used for dust catcher of exploitation, makes dust catcher be convenient to the operator as much as possible and uses, and avoids malfunctioning owing to block simultaneously to a great extent.

According to the present invention, the whizzer that is used for dust catcher of the feature of this task by having claim 1 solves.Other advantageous forms of implementation is the part of the dependent claims relevant with specification and accompanying drawing.

According to the present invention, whizzer is limited on its basic function on the one hand.Dirt collecting receptacle of usually combining with whizzer in the device of routine and fine dust filter are used as independent member structure.Therefore, whizzer itself only comprises that one is used for the air guide member of air-swirl, an air intake and an air outlet slit.On the other hand, has another opening, the closed with covers that this opening is taken apart with a class when work according to whizzer of the present invention.So far from then on set out, promptly whizzer does not need other inlet except the import of air and dust and outlet in this dust catcher, because the outside that is disposed in whizzer as independent member owing to dirt collecting receptacle and fine dust filter is then opened the necessity of whizzer and just do not existed for the emptying dust or in order to clean fine dust filter.Owing to this reason, because the whizzer of this dust catcher is so far constructed as the member of sealing, it only is configured with an air intake that is communicated with dirt collecting receptacle and an air outlet slit that is connected to fine dust filter.Because being provided with another according to the present invention on whizzer now can be with the opening of knock-down closed with covers, therefore the obstruction of contingent whizzer can be by fast and elimination simply.

Advantageously, lid itself can be fixed on whizzer with taking apart.Whizzer continues to remain independent member and can advantageously make and install by cost thus.

In a preferred form of implementation, lid has substituted the coverage rate of the whizzer of cylindricality normally and structure in this wise, makes it to be fixed on internally on the wall of whizzer.Lid and whizzer are produced for revolving necessary airtight basically being connected of branch effect, needn't add other potted component simultaneously.Especially by making lid and whizzer with plastics, lid can only sealed whizzer and coupling part at the cylinder of the guiding air of whizzer or the bearing of the form fit in the cone by it under the situation of the seal that does not have other basically airtightly.

In a favourable form of implementation of the present invention, use a kind of buckle that is used to connect lid and whizzer to be connected.Can realize a kind of connection that can easily discharge thus, it is fixed lid reliably along the longitudinal axis of whizzer.The connection of this very favorable form can realize in this wise that especially promptly lid forms the last coverage rate of cylindricality whizzer.

Advantageously, especially when using vortex tube as whizzer, whizzer lid in process and be used for the reverse cone of air.Under favourable situation, lid and air are oppositely bored the member that can be used as integral body and are made with plastics in injection moulding.This has guaranteed that cost realizes whizzer extremely beneficially.

Other details of the present invention and advantage are by providing in the dependent claims relevant with the description of an embodiment, and this embodiment will contrast accompanying drawing and be elaborated.Shown in the accompanying drawing:

Fig. 1 be have the dirt collecting receptacle that can take off dust catcher decomposition view and

Fig. 2 is the schematic views that has two whizzers of the lid of opening He close respectively.

Fig. 1 shows a kind of dust catcher, and the whizzer element 2 with two whizzers wherein is installed on a lower member 1.The air that will place the neutralization that rotatablely moves to be separated into dust part from the air that contains dust that the dirt pipe enters and clean by whizzer 2 by centrifugal force.Separated dust part will be discharged to the independent dust collecting box 3 from whizzer 2.Dust collecting box 3 can take off from whizzer 2 discretely by handle 4.It is connected with lower member 1 by grab 5 under the state of packing into.By being snapped in, grab 5 forms the buckle connection in the clamp that can not see in the drawings on the lower member.

Under the state of packing into, dust collecting box 3 is connected with lower member 1 by seal 6 and forms negative pressure chamber 7 with it.In order to take off dust bin, can be fixed on the released and deflection of the whizzer element 2 of dust collecting box 3 by grab 8 and open.Then discharge being connected of dust collecting box 3 and lower member 1 by motion grab 5.As shown in Figure 1, dust collecting box 3 can be taken off so that carry out emptying and cleaning with the fine dust filter 9 that is bearing in wherein now.

In Fig. 2, show once more one of whizzer 2 from above the schematic views seen.Whizzer element 2 has two swirl tube separator 21 and 22 that form is the column tube of circular cross section, and they are that minute surface is constructed symmetrically.They respectively have an air intake 23, and it is merely able to see that wherein the air intake that can not see of air intake 23 and swirl tube separator 21 feeds a public air and enters district 24 on the swirl tube separator of opening 22.Air intake 23 is positioned on the bottom of swirl tube separator 22 in this view.The air that contains dust enters into swirl tube separator 22 and enters swirl tube separator 21 by the opening that can not see accordingly by it, is placed in respectively to rotatablely move and be transported to the lid 26 that only can see along the inwall 25 of swirl tube separator 21 and 22 on swirl tube separator 21.Be formed with oppositely awl 27 of air on each lid 26, it can see the sunk part for inwardly turning in Fig. 2.Because air is rotated motion, dust is separated to the inwall 25 of swirl tube separator 22 and passes to dust collecting box 3 by exporting 28 by centrifugal force.The centre of air in swirl tube separator 21 or 22 that oppositely is reversed on the awl at air that has been cleaned moves downward and pass through outlet 29 outflow swirl tube separator 22 downwards.It arrives negative pressure chamber 7 through fine dust filter 9 therefrom, and it is discharged in the environment from here.Be connected by the buckle-type that does not illustrate that each fixes a lid 26 on the inwall 25 of swirl tube separator 21 or 22.This lid can be along axially taking off so that clean swirl tube separator 21,22.
