Below, describe for convenience, a pair of pressing element 270,280 is called the 1st pressing element 270 and the 2nd pressing element 280.
In the present embodiment, at least one the removable inside that is arranged at control of dust body 210 in a pair of pressing element 270,280, thus between a pair of pressing element 270,280, play compression to dust.
Promptly, can counterrotatingly be arranged under the situation of control of dust body 210 inside at the 1st pressing element 270 and the 2nd pressing element 280, the 1st pressing element 270 moves with relative direction rotation with the 2nd pressing element 280, thereby the interval between the side of side of the 1st pressing element 270 and the 2nd pressing element 280 relative with it is narrowed down, thus, will make the dust between the 1st pressing element 270 and the 2nd pressing element 280 obtain compression.
In the present embodiment, the 1st pressing element 270 rotatable inside that are arranged at control of dust body 210, the 2nd pressing element 280 then is fixedly set in the inside of control of dust body 210.
Thus, the 1st pressing element 270 becomes rotating member, and the 2nd pressing element 280 then becomes fixed component.
Say that in more detail the 2nd pressing element 280 preferably is arranged at the inner peripheral surface of control of dust body 210 and constitutes position between the rotating shaft 272 of the 1st pressing element 270 pivots.
That is, the 2nd pressing element 280 is arranged on the face of inner peripheral surface of the axis that connects rotating shaft 272 and the 1st dust storage portion 214.At this moment, the 2nd pressing element 280 will cover the space between the axis of the inner peripheral surface of the 1st dust storage portion 214 and rotating shaft 272 wholly or in part.When the 1st pressing element 270 pushes away dust, the 2nd pressing element 280 will together compress dust with the 1st pressing element 270.
For this reason, an end of the 2nd pressing element 280 preferably is integrally formed at the inner peripheral surface of control of dust body 210, and the other end then preferably is integrally formed on the fixed axis 282 with the rotating shaft 272 coaxial settings of the 1st pressing element 270.
Certainly, also can make and have only an end of the 2nd pressing element 280 to be integrally formed at the inner peripheral surface of control of dust body 210, or have only the other end of the 2nd pressing element 280 to be integrally formed on the fixed axis 282.That is to say that the 2nd pressing element 280 will be fixed in the inner peripheral surface of control of dust body 210 and at least one side in the fixed axis 282 at least.
But, even an end of the 2nd pressing element 280 is not integrally formed at the inner peripheral surface of control of dust body 210, the inner peripheral surface of the preferably close control of dust body 210 of an end of the 2nd pressing element 280.
In addition, even the other end of the 2nd pressing element 280 is not integrally formed on the fixed axis 282, the other end of the 2nd pressing element 280 is preferably near fixed axis 282.
Its reason is, the amount that the slot leakage that the dust that pushed away by the 1st pressing element 270 side by the 2nd pressing element 280 is formed is discharged reaches minimized.
Have as above that the 1st pressing element 270 and the 2nd pressing element 280 of structure preferably constitute rectangular-shaped panel, in addition, the rotating shaft 272 of the 1st pressing element 270 preferably with the axis at the center of formation control of dust body 210 be arranged at coaxial on.
And fixed axis 282 protrudes moulding to the inside at an end of control of dust body 210, forms the mesopore 283 that is used to assemble rotating shaft 272 of axial perforation in the inside of fixed axis 282.In addition, the part of rotating shaft 272 will be inserted into mesopore 283 from the upside of fixed axis 282.
More specifically say, in rotating shaft 272, be formed with the end difference 272c that supports by the upper end of fixed axis 282, and be that benchmark is divided in conjunction with the upper axis 272a of the 1st pressing element 270 and in conjunction with the lower shaft 272b of the driven gear (will be explained below) that makes 270 rotations of the 1st pressing element with end difference 272c.
Except aforesaid structure, also include drive unit in the vacuum cleaner of present embodiment, it optionally is connected in the 1st pressing element 270, is used to make the 1st pressing element 270 to be rotated.
Below, will be in conjunction with Fig. 5 to Fig. 8, the marriage relation of dust collect plant 200 and drive unit is described in detail.
With reference to Fig. 5 to Fig. 8, the drive unit that is used for rotating the 1st pressing element 270 includes: compression motor (will narrate in the back) is used to produce driving force; Power transfering part is used for sending the driving force of compression motor to the 1st pressing element 270.
Power transfering part includes: the driven gear 410 that combines with the rotating shaft 272 of the 1st pressing element 270; Be used for transmitting the driven wheel 420 of power to driven gear 410.Wherein, driven wheel 420 is in conjunction with the rotating shaft of compression motor, and the compression motor driven rotary is arranged.
When compression motor is rotated, the driven wheel 420 that combines with compression motor will be rotated, under the effect of driven wheel 420, the revolving force of compression motor sends driven gear 410 to, and driven gear 410 is rotated, consequently, the 1st pressing element 270 will be rotated along with the rotation of driven gear 410.
The gear shaft 414 of driven gear 410 combines with the rotating shaft 272 of the 1st pressing element 270 at the downside of control of dust body 210.As mentioned above, because driven gear 410 carries out combination at the downside of control of dust body 210, driven gear 410 will expose to the outside of control of dust body 210.
Compression motor is arranged at the below of dust collect plant installation portion 170, and driven wheel 420 combines with the rotating shaft of compression motor, and is arranged at the bottom surface of dust collect plant installation portion 170.
The part of the outer peripheral face of driven wheel 420 is exposed to the outside in the bottom surface of dust collect plant installation portion 170.The bottom surface of dust collect plant installation portion 170 is formed with peristome 173, and peristome 173 is used for the part of driven wheel 420 outer peripheral faces is exposed.
As mentioned above, along with driven gear 410 exposes to the outside of dust collect plant installation portion 170, when in the dust collect plant installation portion 170 dust collect plant 200 being installed, driven gear 410 will mesh with driven wheel 420.
Preferably use as compression motor 570 and can realize positive rotation and contrary motor rotating, that is, compression motor uses can realize the twocouese motor rotating.
Thus, the 1st pressing element 270 can carry out positive rotation and contrary rotation, along with the 1st pressing element 270 carries out positive rotation and contrary rotation, will pile up compressed dust in the two sides of the 2nd pressing element 280.
In order to realize the just contrary rotation of compression motor, can use synchronous motor (synchronous motor) as compression motor 570.
Synchronous motor can be realized just contrary rotation by motor self,, exceeds when the active force that imposes on motor under the situation of setting value in the process that a direction is rotated at motor, will be converted to other direction to be rotated.
At this moment, the active force that imposes on motor is that (moment of torsion: torque), when resistance reaches setting value, the direction of rotation of motor will change the resistance that produces along with the 1st pressing element 270 pressurization dust.
Synchronous motor is the known technology in the technical field of motors, therefore will save detailed description thereof.But, realize that by synchronous motor the viewpoint of the just contrary rotation of drive motors is one of basic fundamental thought of the present invention.
At 270 rotations of the 1st pressing element and compression dust, and reach under the situation on the summit that can't be rotated again, preferably make the 1st pressing element 270 with certain hour persistent pressure dust.Wherein, the summit that the 1st pressing element 270 can't be rotated again refers to, and resistance reaches the situation of setting value.
When resistance reaches setting value, to disconnect the power that is used to rotate the 1st pressing element 270 with certain hour, promptly disconnect the power supply that compression motor connects, thereby under the state that the 1st pressing element 270 stops, keep the compressed state of dust, and through certain hour the time, again compression motor is connected power supply, the 1st pressing element 270 is moved.
Because the power supply cut-off point that inserts in the compression motor is the situation that resistance reaches setting value, when compression motor drives once more, the direction of rotation of compression motor will be opposite with the direction before power supply disconnects.
In order to be easy to carry out the squeeze operation of dust, compression motor preferably makes the 1st pressing element 270 continue just carrying out with unequal angular velocity/contrary rotation.
Compile in the inside of control of dust body 210 under the situation of the dust more than a certain amount of,, preferably show emptying the time of control of dust body 210 to the user for the reduction that prevents dust collecting performance and overload of motor etc.
Will be in body of dust collector 100 or handle (not shown) signalization display part (not shown), when the dust more than the internal reservoir of control of dust body 210 is a certain amount of, thereby the rotating range that makes the 1st pressing element 270 reaches set angle when following, will show that dust empties the time to the user.
Wherein, the signal that sends in the signal display part can be audible signal or visual signal.For example, the signal display part can use loudspeaker or LED.
Downside at control of dust body 210 is formed with the guiding rib 290 that is used to guide dust collect plant 200 installations, is formed with the insertion groove 172 that is used to insert guiding rib 290 in dust collect plant installation portion 170.
Guiding rib 290 constitutes with " C " shape in the outside of driven gear 410, and surrounds the part of driven gear 410.Thus, guiding rib 290 will play the effect of protection driven gear 410, and play and prevent that dust from flowing to the effect of driven gear 410.
In the present embodiment, when dust collect plant 200 is installed on dust collect plant installation portion 170, need make driven gear 410 and driven wheel 420 carry out combination.Guiding rib 290 will make the part of driven gear 410 expose to the outside.
In addition, be provided with inching switch 430 below dust collect plant installation portion 170, inching switch 430 is used to detect the position of rotation of driven gear 410.Inching switch 430 exposes portion of terminal 440 to dust collect plant installation portion 170, and portion of terminal 440 will contact with driven gear 410, and is used for ON/OFF (ON/OFF) inching switch 430.
For this reason, be formed with through hole 177 in dust collect plant installation portion 170, through hole 177 is used to make the part of portion of terminal 440 to expose to the outside.In addition, the outer part at through hole 177 is formed with interior side rib 178 and the outer ribs 179 that is used to protect the portion of terminal of exposing 440.
Below, with reference to Fig. 6 to Fig. 8, the marriage relation of driven gear and inching switch is described.
With reference to Fig. 6 to Fig. 8, inching switch 430 be positioned at driven gear 410 below, the portion of terminal 440 by control inching switch 430 open/close states contacts with the downside of driven gear 410.

As mentioned above, inching switch 430 by with the interaction of driven gear, play the position detection part effect of the reference position that is used to detect the 1st pressing element 270, simultaneously, in ON/OFF (ON/OFF) process of inching switch 430, the effect of the maloperation whether maloperation test section that is used to judge the 1st pressing element 270 will be played.
Below, will describe the effect of the vacuum cleaner in the present embodiment and the compression process of dust.
Figure 18 is the control method flow chart of vacuum cleaner of the present invention.
With reference to Figure 18, the user select in the operation signal input part 520 intensity of suction that shows strong, in, in the weak pattern one, and startup vacuum cleaner, at this moment, control part 510 will be controlled suction motor driver 540 and drive, thereby make suction motor 550 drive (S10) with the suction pattern that the user selects.
When suction motor 550 drives, under the effect of the suction force that sucks motor 550, dust will suck by suction nozzle.And, will flow into the inside of body of dust collector 100 by body suction portion 110 by the suction nozzle inhaled air, leaked-in air will enter into dust collect plant 200 via set path.
In addition, the air that enters into dust collect plant 200 will be through discharging body of dust collector 100 after the dust separation process, and the dust of separation will be stored in the 1st dust storage portion 214.
As mentioned above, aerial dust is separated, and stores in the 1st dust storage portion 214 in the process of dust, and a pair of pressing element 270,280 will compress the dust that stores in the 1st dust storage portion 214.
That is, in order to compress the dust that stores in the dust collect plant 200, control part 510 will make compression motor 570 drive (S11).
