As preferably, V-shape separator opening is inside.
Be connected with a point stream interface 4031 for wind deflector 403 along spiral involute direction because motor room 402 exports, the space of filter cloth bag 4041 on the left of point stream interface 4031 is less, and it is larger in point stream interface 4031 rightward space, as preferably, as shown in figure 14, the V-shape separator of point stream interface 4031 is set closer on the left of point stream interface 4031, thus forms little left air path and larger right air path, make air-flow evenly can enter space, point stream interface 4031 left and right sides.
As preferably, sedimentation mouth 405 is oval.Sedimentation mouth 405 is set to oval one side can obtain larger dust collecting space than circle in the confined space, and sealing effectiveness is better than square on the other hand.
Shown in Fig. 6, vehicle body 7 is made up of snail like shell body 701, pilot set 702, operation handrail 703, snail like housing 701 is for the sealing of dust rubbish separating and filtering device 4 and protection, pilot set 702 bottom is cavity structure, inner placement power pack 5 and control system 6, operation handrail 703 is arranged on deflecting wheel support bracket 101.
Shown in Figure 15, snail like housing dead astern arranges buffering exhaust mouth 7011, for discharging the air after dust rubbish separating and filtering device 4 filters.
As preferably, as shown in figure 16, screen cloth 406 is T-shaped structure, rubbish storage case 407 is divided into two separate space, after dust rubbish enters separate space 1 by rubbish storage case 407 entrance, rubbish is stored in this space, dust goes upward to motor room 402 through screen cloth 406 under suction, when sucking the floating thing containing similar plastics bag in rubbish, above separate space 1, screen cloth is blocked, now dust enters separate space 2 4062 at suction from separate space 1 side, motor room 402 is entered through screen cloth above separate space 2 4062, T-shaped screen cloth 406 can guarantee that described dust rubbish separating and filtering device 4 still can possess normal suction after suction floating thing.
As preferably, as shown in figure 17, also comprise annular clearing apparatus, described annular clearing apparatus comprises dust shield 801, connecting hose 802 and hose fixing support 803, described connecting hose is toroidal bend structure, and when needs cleaning tree well, self-priming for described miniature electric road-sweeper can stop near tree well by driver, rotate hose fixing support 803 and can clean whole annular region, such as tree well region.
As preferably, described hose fixing support and Fig. 9,10 rocker-arm link mechanism 31 be connected.By the rotation of rocker-arm link mechanism, realize ring-type cleaning, comprise and cleaning around tree well.About rocker-arm link mechanism 31 with identical above, be just not described further.
As preferably, as shown in Figure 18 ~ Figure 19, mechanical assistance sealing device comprises motion arm 901, pull bar 902, push rod 903, rubber ring 904, disposal box bracket 905, wherein pull bar 902 attended operation arm 901 and push rod 903, one end of motion arm 901 arranges transverse axis 1, motion arm 901 and transverse axis 1 lay respectively at the both sides of axis of rotation, push rod 903 one end arranges transverse axis 2 9031, push rod 903 and transverse axis 2 9031 lay respectively at the both sides of the second axis of rotation (by push rod 903, transverse axis 2 9031 and the second axis of rotation become push rod component), when motion arm 901 rotates around axis of rotation, drive transverse axis 9011 also along with upwards rotating, drive pull bar motion simultaneously, pull bar drives push rod 903 to move downward, thus transverse axis 2 9031 is moved upward, thus promotion disposal box moves upward, thus compresses seal 904 seals.When transverse axis 1 turns to top dead centre (push rod 903 and motion arm 901 are positioned at upright position or close to upright position), the decrement of disposal box to rubber seal reaches maximum value, because the principle of active force and reaction force, normal pressure between motion arm 901 rotating shaft and disposal box bracket 905 reaches maximum value, now motion arm 901 needs are overcome great stiction could continue clockwise direction rotate, therefore the object of motion arm 901 automatic locking is reached, drive pull bar 902 that the push rod 903 be connected with pull bar 902 is also rotated around the axle be fixed on disposal box bracket 905 while motion arm 901 rotates, be positioned at the transverse axis 2 9031 on push rod 903 top by disposal box 408 rear end jack-up, based on the locking principle that biconditional operation arm 901 is identical, when transverse axis 2 9031 arrives top dead centre, push rod 903 also automatic locking, after disposal box 408 is by jack-up, the compression rubber ring 904 be installed between disposal box 408 and sedimentation mouth 405 realizes the sealing of the junction between disposal box 408 and sedimentation mouth 405.
