Figure 10 is the side view of the state that the sucking mouth 6 of embodiments of the present invention advances.
As shown in Figure 10, body brush (nylon loop) 30b of the second rotary cleaning body 30 is larger than the contact resistance of body brush (nylon loop) 30b and ground M with the contact resistance of partition wall bend 11e, therefore non rotating, can prevent the dust be attracted in suction chamber Q2 to be swept out rear to suction inlet main body 11.The rotation due to the first rotary cleaning body 20 particularly can be suppressed to be attracted to dust bullet in suction chamber Q2 rearward, to fly out to the rear of suction inlet main body 11.
The dust DS be attracted is transported to the path of suction inlet connector 13 by stream R (with reference to Fig. 3) from suction chamber Q2 (with reference to Fig. 6), afterwards, the dust collecting part 2b (with reference to Fig. 1) of main body of dust collector 2 is attracted to by extension tube 5, operation pipe 4 and hose sections 3.Pass through in the never illustrated filter of air after being removed dust by dust collecting part 2b and electric blower 2a, be discharged to the outside (with reference to Fig. 1) of main body of dust collector 2.
Like this, according to the present embodiment, the second rotary cleaning body 30 connected with ground M is provided with at the rear of the first rotary cleaning body, thus, when making sucking mouth 6 retreat (when sucking mouth 6 is pulled back), second rotary cleaning body 30 rotates due to the contact resistance with ground M, the dust at the rear of suction inlet main body 11 can be sucked in suction chamber Q2 thus.
In addition, when making sucking mouth 6 advance (when sucking mouth 6 is pushed away forward), because the rotation of the second rotary cleaning body 30 is limited, so can prevent from being swept out rear to suction inlet main body 11 by the first rotary cleaning body 20 dust swept in suction chamber Q2.
In addition, according to the present embodiment, do not need to arrange the mechanism of movable part as the direction of rotation of restriction second rotary cleaning body 30, therefore structure is simple.In addition, the possibility causing limitation function to suffer damage due to entering of sand and dust etc. is also little.
In addition, in the present embodiment, the front end of body brush (nylon loop) 30b of the second rotary cleaning body 30 has the bristle height with the whole surface contact of partition wall bend 11e, but whole surface contact that is non-essential and partition wall bend 11e, such as shown in figure 11, in the inner side of partition wall bend 11e, the projection 35a that cross sectional shape is general triangular is set, 35b, 35c, bristle height is set in the mode of the front end in contact making these projections and body brush (nylon loop) 30b, thus, at direction of rotation W2, frictional resistance is little, almost freely rotate, but at direction of rotation W3, frictional resistance is large, almost become lock-out state.
Further describe, the rotary driving force of the second rotary cleaning body 30 is the frictional force of body brush (nylon loop) 30b and ground M, and the rotation brake power of the second rotary cleaning body 30 is the frictional force of body brush (nylon loop) 30b and projection 35a, 35b, 35c.The microfibre of nylon loop 30b tilts in a circumferential direction relative to cylindrical shell 30e, and its incline direction is rearward go from the front of sucking mouth 6 in the position of body brush (nylon loop) 30b and ground.Therefore, when making sucking mouth 6 advance, the frictional force i.e. rotary driving force of the second rotary cleaning body 30 of nylon loop 30b and ground M diminishes, the frictional force i.e. rotation brake power of the second rotary cleaning body 30 of body brush (nylon loop) 30b and projection 35a, 35b, 35c becomes greatly, and the rotation of the second rotary cleaning body 30 is limited.Otherwise, when making sucking mouth 6 retreat, the frictional force i.e. rotary driving force of the second rotary cleaning body 30 of nylon loop 30b and ground M becomes large, the frictional force i.e. rotation brake power of the second rotary cleaning body 30 of body brush (nylon loop) 30b and projection 35a, 35b, 35c diminishes, and the second rotary cleaning body 30 rotates.
In addition, in the present embodiment, describe when the direction of rotation of the second rotary cleaning body 30 is W3, almost become the situation of lock-out state, but non-essential locking, as long as under the state of advancing at sucking mouth 6, the rotation of the second rotary cleaning body 30 is slack-off compared with time free, just can prevent from being swept out rear to suction inlet main body 11 by the first rotary cleaning body 20 dust swept in suction chamber Q2.
In addition, in the present embodiment, the surface of the second rotary cleaning body 30 is provided with body brush (nylon loop) 30b, body brush (nylon loop) 30b is arranged in the mode contacted with a part for sucking mouth 6, and be set to tilt in a circumferential direction, make to allow spinning movement and in the spinning movement of advance limit when sucking mouth 6 retreats, but be not limited thereto.As long as play the rotation limiting a direction when rotated, the parts allowing the effect of the rotation in another direction, installation method with simple structure.The body brush of present embodiment (nylon loop) 30b is such as made to be that elastomer also can obtain above-mentioned effect.
According to present embodiment described above, can with simple structure, advance time make the second rotary cleaning body 30 almost regularly with earth surface, therefore, it is possible to make the dust sucked from front not easily be expelled to the rear of the second rotary cleaning body 30, and, when retreating, the second rotary cleaning body 30 rotates, and by the conveyance of the dust at the rear of sucking mouth 6 to suction chamber Q2, can suppress the not thorough of dust suction.In addition, in the present embodiment, be illustrated to use first rotary cleaning body with to the situation that this first rotary cleaning body carries out the motor of rotary actuation, but the attraction utilizing the electric blower 2a of main body of dust collector 2 to produce drives the first rotary cleaning body or does not arrange the first rotary cleaning body and also can obtain identical effect.
