On the other hand, compare with air, have quality because of the dust of the wind path 62 that is inhaled into dust separation portion 60, thus because of its inertia directly advances to wind path 62, be subjected to head board 100 guiding wall portion 101 guiding and be imported in the dust storage chamber portion 55.That is, by dust separation portion 60 separation of air and dust, the dust that is separated to dust storage chamber portion 55 by control of dust.

And, the air that directly advances to wind path 62 be subjected to head board 100 guiding wall portion 101 guiding and be imported in the dust storage chamber portion 55.Be imported into the air in this dust storage chamber portion 55, the filter F 2 of rear wall 55H by dust storage chamber portion 55, be inhaled into the negative pressure chamber 57 of dust collecting container 50, then the pleated filter body P of the rear aperture 51 by dust collecting container 50 and connect the suction opening 24 that wind path G is attracted to electric blower 23.

After dust suction finishes, the switch 13a of operating portion 13A is operated, stop the driving of electric blower 23.Then, if press the button 42 of body of dust collector 11 downwards, then extremely shown in Figure 22 as Figure 20, the application of force of handle 85 antagonistic spring S1, S1 is pressed downwards.

If press this handle 85 downwards, then press head board 100 downwards by interlinked mechanism 70.

When pressing this head board 100 downwards, the blade 107 of the head board 100 filter plane F2a of filter F 2 that is slidingly connected, and will sweep attached to the dust of this filter plane F2a.And, by pressing head board 100, the dust that accumulates in dust storage chamber portion 55 is compressed.Therefore, can in dust storage chamber portion 55, accumulate more dust.

If hand leaves button 42, then handle 85 utilizes the motive force of spring S1, S1 to return to original position, and as shown in Figure 5, head board 100 and button 42 return to original position linkedly with this handle 85.

Then, the situation of outwelling the dust that accumulates in dust storage chamber portion 55 is described.

At first, open the lid 40 of body of dust collector 11, take out dust collecting container 50.Then, if press as shown in Figure 6 operating portion 91A, then to make bottom 59 be the center with axis J1 to switching mechanism 90, opens after arrow P 1 direction is rotated.

Then, if hold handle part 54 and handle 85 in the lump, then as shown in figure 23, press lower handle 85 to handle part 54, by pushing this handle 85, as shown in figure 10, utilize interlinked mechanism 70, head board 100 is pressed till the position of abundant discharge dust.Thus, can release dust in the dust storage chamber portion 55 downwards, become very easy so fall dust from the bottom opening of dust collecting container 50.

In the time of in forgetting the dust collecting container chamber 21 that dust collecting container 50 is installed in body of dust collector 11, the suction opening 24 of electric blower 23 directly is communicated with by guiding wind path G with the dust collecting container chamber 21 of body of dust collector 11.Under this state, if the switch 13a of the operating portion 13A of hand-held pipe 13 is operated, then drive electric blower 23, form negative pressure in the dust collecting container chamber 21.

As shown in Figure 4, utilize this negative pressure, the button 42 of lid 40 is pressed downwards by the application of force of antagonistic spring (not shown) ground, so open in the hole 41 of lid 40.Thus, outer gas is directly imported the dust collecting container chamber 21 of body of dust collector 11 by hole 41, therefore from sucking air hardly at the section port body of being operated by dust suction face 15 that has more dust.That is, can prevent to suck dust from section port body 15.

Therefore, can prevent from directly to be inhaled into unfavorable condition in the electric blower 23 from the dust that section port body 15 sucks.And, when the upstream side of electric blower 23 is provided with aflter-fillter (not shown), can prevent to stop up at once this aflter-fillter.In addition, can prevent following unfavorable condition, promptly section port body 15 sucks harder foreign matter, and this foreign matter is inhaled in the electric blower 23 after breaking through aflter-fillter, damages electric blower 23.

And, under the state that dust collecting container 50 is not installed, by being arranged on the hole 41 on the lid 40, make in the dust collecting container chamber 21 and directly be communicated with outer gas, therefore, carrying when waiting comparatively facility even under the state that dust collecting container 50 is not installed, also can close lid 40.

In addition, the hole 41 with the action button 42 that makes dust compression usefulness is given prominence to is also used as in order to outer conductance is gone into the hole of dust collecting container chamber 21, can simplify the structure of body of dust collector 11 thus.

And, because can pull down head board 100, so can remove dust that enters on the head board 100 etc. from bar 104,104.

Figure 24 represents the part of other routine dust collecting containers 150.This dust collecting container 150 makes head board 200 turn to till the position that is represented by dotted lines around axle 201 by interlinked mechanism 70.And, filter F 2 is formed circular-arc, when head board 200 is rotated, make the filter plane F2a and the dedusting mechanism of filter F 2, promptly blade 107 is slidingly connected, and releases the dust of dust storage chamber portions 55 with head board 200.202 is opening.

Yet, by the negative pressure of dust collecting container chamber 21, the button 42 that makes lid 40 moves downwards opening hole 41, and the size of the application of force by the spring (not shown) that will exert pressure to button 42 is set at setting, when outer air-flow during, can make button 42 up-down vibration thus through hole 41.Also can send and report sound by the vibration of this button 42.At this moment, button 42 and spring constitute notifying operator.

And, also can vibrating mass or alarm features be set 41 places in the hole, with to forgetting that the situation that dust collecting container 50,150 is installed gives a warning, wherein vibrating mass 41 produces and vibrates to sound through the hole by making outer air-flow.

Among the described embodiment, release the dust of dust storage chamber portion 55 with head board 100,200, but also can not release dust.That is, head board 100,200 also can be used for removing attached to the dust on the filter F 1 by blade 107.At this moment, by head board 100 (200), blade 107, and interlinked mechanism 70 constitute dedusting mechanisms.

At this moment, button 42 is to be exclusively used in the button that makes dedusting mechanism work.

According to the present invention, even do not drive electric blower installing under the state of dust collecting container, also can stop to suck dust from section port body, therefore, can prevent dust is sucked in dust collecting container chamber or the electric blower.

And, according to the present invention, even dust collecting container is not installed, also can close the lid of control of dust vessel and carry body of dust collector, therefore the technology of No. 3297224, structure of the present invention and described Japanese patent laid-open 1-291821 number, Japan Patent is different, the technology that No. 3297224, described Japanese patent laid-open 1-291821 number, Japan Patent can't be closed the lid of control of dust vessel when paper bag or dust bag are not installed, perhaps can't set body of dust collector.And the present invention is when dust collecting container is not installed, and follows the driving of electric blower and structure that outer conductance is gone into the dust collecting container chamber, and the structure that the Japan Patent spy who imports outer gas when stopping up with dust opens announcement in 11-9526 number is different.

The present invention is not limited to described embodiment, and can carry out various distortion, change to these embodiment.

For example, in described embodiment, whether dust collecting container chamber 21 is irrelevant with dust collecting container 50 having been packed into, the application of force by not shown spring, make the switching parts always close closed pore, but also can when dust collecting container being installed in the dust collecting container chamber, make to open and close parts pass closed pore, and when dust collecting container not being installed to the dust collecting container chamber, make the switching parts open the hole.
