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 is entered 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, separate space 1 screen above is blocked, now dust suction from separate space 1 side enter separate space 2 4062, motor room 402 is entered through separate space 2 4062 screen above, T-shaped screen cloth 406 can ensure that described dust rubbish separating and filtering device 4 remains to possess normal suction after sucking floating thing.
As preferably, the volume of separate space one is more than the volume of separate space two.
As preferably, as shown in figure 17, also include annular clearing apparatus, described annular clearing apparatus comprises dust shield 801, connects flexible pipe 802 and hose fixing support 803, described connection flexible pipe is toroidal bend structure, and when needs clean tree well, self-priming for described miniature electric sweeper can be stopped 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 is connected with the rocker-arm link mechanism 31 of Fig. 9,10.Rotation by rocker-arm link mechanism, it is achieved ring-type cleaning, cleans including around tree well.About rocker-arm link mechanism 31 with as before, just it is not described further.
nullAs preferably，As shown in Figure 18～Figure 19，Mechanical assistance sealing device includes 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 rotary shaft，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 rotary shaft (by push rod 903、Transverse axis 2 9031 and the second rotary shaft become push rod component)，When motion arm 901 rotates down around rotary shaft，Drive transverse axis 9011 also with being rotated up，Drive pull bar motion simultaneously，Pull bar drives push rod 903 to move downward，So that transverse axis 2 9031 moves upward，Thus promote disposal box to move upward，Thus compresses seal 904 seals.nullWhen 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)，Disposal box reaches maximum to the decrement of rubber seal，Because active force and the principle of counteracting force，Normal pressure between motion arm 901 rotating shaft and disposal box bracket 905 reaches maximum，Now needs are overcome great stiction could continue rotationally clockwise by motion arm 901，Therefore the purpose of motion arm 901 automatic locking is reached，Motion arm 901 drives pull bar 902 to make the push rod 903 being connected with pull bar 902 also rotate around the axle being fixed on disposal box bracket 905 while rotating，It is 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 rubber ring 904 that compression is installed between disposal box 408 and sedimentation mouth 405 realizes the sealing of the junction between disposal box 408 and sedimentation mouth 405.
As preferably, can only include motion arm 901 and transverse axis 1, and not include push rod 903, the parts of transverse axis two, in such cases, it is preferable that the rotary shaft of motion arm 901 is arranged on the middle part of bracket 905.
As preferably, multiple push rod component can be set, such as, be arranged on the middle part of bracket 905.
