Abstract

The vacuum cleaner has a closable air inlet (9) in the suction hose connector for equalizing the pressure between the inside (10) and outside (6) of the dust bag.

Description

Dust catcher

Technical field

The present invention relates to a kind of dust catcher, a suction motor extend in the dirt receptacle of this dust catcher, is provided with one and is used for the suspension arrangement that foul is handled bag in dirt receptacle, and dirt receptacle has a suction inlet that feeds in it and takes over.

Background technology

A kind of have a dust bag from the known dust catcher of DE8907219U1 at a retainer ring, wherein, for the balance air pressure, one or more passages is set between dust bag and container.Otherwise airtight dust bag can tighten to a great extent and can only receive a spot of dust.

But such dust catcher can be handled bag, paper filter by foul selectively or not want these parts and carry out work in the aspiration container by directly being drawn into.As long as use comparatively ventilative paper filter or do not want any filter work, then this problem can not occur, so passage is not only and under ventilative paper filter situation or even disadvantageous unwanted.Last thin dust is not to keep hanging in the paper filter, but has directly entered into dirt receptacle and may cause the fault of suction motor.

Summary of the invention

Task of the present invention is, a kind of dust catcher is provided, and wherein dirt receptacle can not rely on the working method that has or do not have foul processing bag or paper filter and always receives maximum volume.

According to the present invention, this puts following realization, a kind of dust catcher is promptly proposed, a suction motor extend in the dirt receptacle of this dust catcher, in dirt receptacle, be provided with one and be used for the suspension arrangement that foul is handled bag, dirt receptacle has a suction inlet that feeds in it and takes over, wherein, handle the pressure of bag for the balance foul, handle between the inboard of bag and the outside at the foul of a suspension passage is set, it is characterized in that, have only a passage be arranged on suction inlet take in and this passage be closable.Now when using air-locked foul to handle bag, produce identical pressure opening under the situation of passage to handle between the inboard of bag and the outside at foul, make the whole volumes that obtain its reception foul thus.On the contrary, when using paper filter and handle bag or paper filter at foul not and directly be drawn under the situation in the dirt receptacle, passage is closed.This opening and closing that replace have only in practice and have only a passage on the one hand and just have meaning under the operator can realize well on the other hand the situation.

For can selectively closing or open passage, on suction inlet is taken over, a revolving valve is arranged.It is rotatably supported on the passage and by two semicanals forms, and one of them semicanal has the less diameter of an open passage, and second half pipe has a bigger diameter of closing passage.

Advantageously, the revolving valve that is used to regulate stretches out suction inlet and takes over and enter in the dirt receptacle and open circumferential weld between the inner space of passage and dirt receptacle on the revolving valve position of opening.Because to handle revolving valve when foul just in time of the same type is handled bag be undesirable putting into, or even harmful, therefore have a mind to abandon adjusting possibility from the outside.Only the occasion of the operation of switching between foul is handled bag, paper filter or do not used just needs corresponding adjusting, and can carry out corresponding adjusting extending on the inner part of revolving valve at that time.In addition, be equalizing pressure, a circumferential weld is set on revolving valve.

Description of drawings

Accompanying drawing is represented one embodiment of the present of invention.Wherein:

Fig. 1 represents the cross-sectional view of a dust catcher,

The partial view that amplifies in Fig. 2 presentation graphs 1,

Fig. 3 represents the III-III sectional view according to Fig. 2, has the passage of opening,

Fig. 4 represents the sectional view according to Fig. 3, has the passage of closing,

Fig. 5 represents the V-V sectional view according to Fig. 2.

The specific embodiment

A suction motor extend in the dirt receptacle 1 of a dust catcher.In addition, in it, feed a suction inlet and take over 3.In dirt receptacle 1, be provided with one and be used for the suspension arrangement 4 that foul is handled bag 5.At this, in the present embodiment, foul is handled bag 5 and is placed on the edge of dirt receptacle 1, and shifts suction inlet onto with plate 16 and take on 3.

Handle at foul between the edge of bag 5 and dirt receptacle 1 and do not get rid of little blow-by place, make gas leakage 8 can enter into and handle space 6 between the bag 5 at the wall 7 of dirt receptacle 1 and foul.Produce this danger thus, foul is handled bag 5 and is tightened, and greatly reducing thus will be by the foul volume of its reception.

Handle the inside of bag 5 and the different pressure dependence in space 6 for being equilibrated at foul, take in 3 at suction inlet a passage 9 is set, be created in space 6 and foul by this passage and handle connection between the inner space 10 of bag 5.Stop foul to handle the deflation of bag 5 thus.Yet when replacing now air-locked foul to handle bag 5 using the ventilative paper filter of a phase time, must close closed pore 9, because otherwise, thin dust directly separates in dirt receptacle 1 rather than in paper filter and remains there.

For can easily opening and closing passage 9, take over 3 inside at suction inlet and support a revolving valve 11 for this purpose.Known to from Fig. 3 and Fig. 4, this revolving valve generally is positioned on the passage 9, is made up of two semicanals, and one of them semicanal 12 has less diameter, and another semicanal 13 has bigger diameter.On the position according to the revolving valve 11 of Fig. 4, passage 9 is capped, thereby and close, and according to Fig. 3 after rotating 180 °, passage 9 is by open.Revolving valve 11 stretches out the inside that suction inlet adapter 3 enters into dirt receptacle 1 with a part 15.Circulation for the air that still keeps flowing through passage 9 there is provided with a circumferential weld 14, and it is handled bags 5 inner space 10 to passage 9 and foul in the relevant position of revolving valve 11 and is communicated with.

Now when the foul of putting into or take out an any kind in dirt receptacle 1 is handled bag, can be at revolving valve 11 take adjustment from suction inlet adapter 3 parts of stretching out 15 according to the hope of Fig. 3 or Fig. 4.At this, revolving valve 11 is only on the occasion that air-locked foul is handled bag 10 turns to position according to the open passage 9 of Fig. 3, and on all other occasions turn to closed position according to Fig. 4.
