Swivelling pipe 12 sets along fore-and-aft direction, is connected with at its leading section and sucks wind path 99, and this suctions wind path 99 forms the rear portion that expansion is opened shape and is communicated to suction chamber 21 to the front side.In addition, this swivelling pipe 12 by lower house 16 with upper shell 17 clampings become can be along circumferential rotation.
Then, the action to above-mentioned the 1st embodiment describes.
At first, the operator is communicated with and connects hose body 4 successively, prolongs pipe 8 and section port body 9 on the main body suction inlet 3 of main body of dust collector 1.
And then after the operator pulled out mains cord and is connected on the not shown socket from main body of dust collector 1, when controlling handle part 6 and operating predetermined setting button 7, according to set the mode of operation that button 7 is set by this, electric blower 2 was driven.
And then the operator controls handle part 6, makes section port body 9 on the ground along the front and back walking as shown in Figure 8, and dust is sucked from suction inlet 15 with air, by prolonging pipe 8 and hose body 4, from main body suction inlet 3 dust is transported and traps the dust bag.
Here, by making roller 58 kiss the earths with respect to the axis of rotation A off-centre of gyroscope wheel main body 57, thereby gyroscope wheel 48 by means of with the contact resistance on this ground etc., turn round in the mode of the direction of travel of the suction inlet main body 11 of following section port body 9.
Follow this revolution, cam part 68 is carried out the off-centre revolution with respect to main body axial region 62, thus, the detection roller 74 that contacts with the peripheral part rolling of this cam part 68 makes the front swing of arm 72 corresponding to the concaveconvex shape of the peripheral part of cam part 68, corresponding to the concaveconvex shape of this cam part 68, sense switch 71 is connected, is disconnected.
Promptly, detecting roller 74 along under the situation of the peripheral part rolling contact in the 1st zone 75 of cam part 68, arm 72 is not gone into to sense switch 71 side pressures, keep the state that leaves with respect to sense switch 71 by active force, in the present embodiment, sense switch 71 disconnects, being judged as suction inlet main body 11 by control module 28 is advancing, and, detecting roller 74 along under the situation of the peripheral part rolling contact in the 2nd zone 76 of cam part 68, arm 72 overcomes active force and is pressed into, and sense switch 71 is connected, and is judged as suction inlet main body 11 by control module 28 and is retreating.
Consequently, sense switch 71 is connected, is disconnected corresponding to the direction of travel of section port body 9, and this connection, the testing result that disconnects are output to control module 28.
When this rotates, make rotary cleaning body 26 have the direction rotation of predetermined relationship along direction of travel with suction inlet main body 11, in the present embodiment, make rotary cleaning body 26 with respect to the direction of travel of suction inlet main body 11 along in the other direction, be the rightabout rotation.In other words, become at sense switch 71 under the situation of off-state, rotary cleaning body 26 is rearward rotated, become at sense switch 71 under the situation of on-state, rotary cleaning body 26 is forwards rotated.
Here, because roller 58 is with respect to the axis of rotation A off-centre of gyroscope wheel main body 57, therefore, when the direction of travel that makes suction inlet main body 11 shown in Fig. 1 (a2) and Fig. 1 (a3) like that is reverse, shown in Fig. 1 (b2) and Fig. 1 (b3), the switching of the direction of rotation of the rotary cleaning body 26 that is undertaken by control module 28 has been delayed the following time: begin to turn round by predetermined angular up to this gyroscope wheel 48 from the revolution of gyroscope wheel 48, the connection of the sense switch 71 of detecting unit 67, disconnect and to be switched, detect the time till the direction of travel of suction inlet main body 11.That is, with respect to the timing of the actual switching of the direction of travel of suction inlet main body 11, the timing of switching that the revolution of detecting unit 67 by gyroscope wheel 48 detects the direction of travel of suction inlet main body 11 can produce delay.
Therefore, because during this time delay, rotary cleaning body 26 is kept along the rotation of the direction of travel of suction inlet main body 11, therefore, needn't carry out complicated control with control module 28 grades, just can between the direction of rotation of the direction of travel of suction inlet main body 11 and rotary cleaning body 26, have multiple relation, thereby can improve the cleaning performance.
Specifically, the rotary cleaning body 26 that when suction inlet main body 11 is advanced, rearward rotates like that shown in Fig. 1 (a1) for example, when shown in Fig. 1 (a2) and Fig. 1 (a3), suction inlet main body 11 being switched to retreat from advancing, up to follow this switching as Fig. 1 (b1) to shown in Fig. 1 (b3) like that, during gyroscope wheel 48 revolution and detecting unit 67 detect till the switching of direction of travel, shown in Fig. 1 (a2), the relation of the direction of rotation of suction inlet main body 11 and rotary cleaning body 26 is kept the relation with common opposite states, promptly, keeping to the direction of travel with suction inlet main body 11 is the identical direction rotation in rear, therefore, by the rotation of this rotary cleaning body 26, can assist the mobile of section port body 9.
In addition, according to the shape of cam part 68 and by detecting roller 74 contacts the sense switch 71 that carries out with the rolling of the peripheral part of this cam part 68 connection, disconnection, detect the angle of revolution of gyroscope wheel 48, therefore, with a plurality of sensors are configured in gyroscope wheel 48 around and detect the situation of angle of revolution etc. of gyroscope wheels 48 by these sensors different, to whole 360 ° angle of revolution arbitrarily, detecting unit 67 can be corresponding continuously.
In addition, because the arm 72 of sense switch 71 is outstanding obliquely with respect to cam part 68, therefore,, there are the situation of swing easily and the situation that is difficult to swing according to the direction of rotation of this cam part 68.Therefore, distolateral by making gear part 78 be displaced to axial another with respect to roller bodies 77, thereby when switching the direction of travel of suction inlet main body 11, make gyroscope wheel 48 turn to the direction of regulation easily, make this rotation direction become arm 72 direction of swing easily, thus, by the revolution of gyroscope wheel 48, the connection of change detection switch 71, disconnection reliably.
And owing to make gear part 78 be formed on the part of the outer peripheral face of roller bodies 77, so compare with the situation of the whole outer peripheral face kiss the earth of roller bodies 77, roller 58 narrows down with the trace width that contacts on ground, and this contact vestige is difficult for staying.
In addition, by contact site being formed outstanding a plurality of gear part 78 of being arranged to gear-like, thereby even roller bodies 77 produces flexible deformations, gear part 78 also can with ground interlock reliably, gyroscope wheel 48 is turned round reliably.
And, owing to have such section port body 9, thus the ease of use of electric dust collector can be improved.
Then, with reference to Figure 10 the 2nd embodiment is described.And,, give prosign and omit its explanation structure and the effect identical with above-mentioned the 1st embodiment.
The 2nd embodiment as Figure 10 (a1) to Figure 10 (a3) and Figure 10 (b1) to shown in Figure 10 (b3), control module 28 makes rotary cleaning body 26 rotate along positive direction with respect to the direction of travel by detecting unit 67 detected suction inlet main bodys 11.That is, control module 28 is under the situation of off-state at sense switch 71, and rotary cleaning body 26 is forwards rotated, and is under the situation of on-state at sense switch 71, and rotary cleaning body 26 is rearward rotated.
And then, in the 2nd embodiment, because roller 58 is with respect to the axis of rotation A off-centre of gyroscope wheel main body 57, therefore, when the direction of travel that makes suction inlet main body 11 shown in Figure 10 (a2) and Figure 10 (a3) like that is reverse, shown in Figure 10 (b2) and Figure 10 (b3), the following time of switching delay of the direction of rotation of the rotary cleaning body 26 that is undertaken by control module 28: turn round along predetermined angular up to gyroscope wheel 48, the connection of the sense switch 71 of detecting unit 67, disconnect and to be switched, detect the time till the direction of travel of suction inlet main body 11.
Therefore, because during this time delay, rotary cleaning body 26 is kept the rightabout rotation along the direction of travel of suction inlet main body 11, so needn't carry out complicated control with control module 28 grades, just can between the direction of rotation of the direction of travel of suction inlet main body 11 and rotary cleaning body 26, have multiple relation, thereby can improve the cleaning performance.
Specifically, the rotary cleaning body 26 that when suction inlet main body 11 is advanced, forwards rotates like that shown in Figure 10 (a1) for example, shown in Figure 10 (a2) and Figure 10 (a3), make like that suction inlet main body 11 in the past heading retreat when switching, up to follow this switching as Figure 10 (b1) to shown in Figure 10 (b3) like that, during gyroscope wheel 48 revolution and detecting unit 67 detect till the switching of direction of travel, shown in Figure 10 (a2), the relation of the direction of rotation of suction inlet main body 11 and rotary cleaning body 26 is kept the relation with common opposite states, promptly keep to the direction of travel with suction inlet main body 11 is the rotation in opposite the place ahead, rear, therefore, by the rotation of this rotary cleaning body 26, can improve the effect of sweeping dust from ground.
And, in the respective embodiments described above, even the connection of sense switch 71, disconnection are on the contrary, promptly, arm 72 is connection when outstanding state, arm 72 is to disconnect when bulged-in state, and is corresponding with it by the various circuit that make control module 28 grades, also can similarly constitute with the respective embodiments described above.
In addition, in suction inlet main body 11, front shroud 19 structure on every side that comprises front side suction inlet 18 is not limited to said structure, even the section port body 9 of these front side suction inlets 18 and front shroud 19 etc. for example is not set, also can reach same action effect.
In addition, as long as can detect the direction of travel of suction inlet main body 11 according to the angle of revolution of the gyroscope wheel corresponding with the direction of travel of suction inlet main body 11 48, then the structure of detecting unit 67 and cam part 68 and shape etc. are not limited to said structure.
And,, also can use roller 58 parts in addition as contact component.
In addition, the angle of the direction of travel of each central angle in each zone 75,76 of cam part 68 suction inlet main body 11 that can detect according to hope etc. is at random set.
And then the direction of rotation that is not limited in rotary cleaning body 26 is controlled to be the predetermined direction that has predetermined relationship with the direction of travel of suction inlet main body 11, if rotary bodies such as driving wheel also can reach same action effect.
And then, the thin portion of electric dust collector is not limited in said structure, as electric dust collector, be not limited in pot type, for example, also can be electric dust collector of self-propelled etc., in addition, for example section port body 9 is formed directly into the following vertical or portable etc. of main body of dust collector 1, also can correspondingly with it use.
