Description

a vacuum cleaner

technical field

The utility model relates to a sanitation device, in particular to a small dust collector.

Background technique

The working principle of the small-sized cleaning vehicle of sanitation equipment in the prior art is to collect garbage and dust particles by cleaning first and then vacuuming. It is a mechanical dust removal operation method, which relies on the rotary brush of the sweeper to clean and remove the dust on the ground. Although the cleaning efficiency is relatively high, the disadvantage is that it is easy to generate dust, secondary pollution, and the cleanliness of the ground is not good. Another way is to spray water mist first and then clean. Although the dust has been reduced in this way, part of the dust has turned into mud and stuck to the ground, making it impossible to clean thoroughly. After the mud dries, it becomes dust again. This problem restricts the cleaning effect of sweeper, and also restricts the popularization and application of sweeper.

The current small sweepers are divided into two types in form: one is a driving type, and the other is a hand-push type without walking power. The driving type generally has a relatively large shape and is not suitable for small areas such as workshops. The whole vehicle also needs to consider the driving space of people. The remaining dust storage space of the whole vehicle is generally relatively small, generally no more than 100L, which seriously shortens the cleaning cycle. Although the hand-push type is small in size, it can also clean the dust in a small space, but it is powerless to the dust on the surface of the equipment and in the pit. Because it is pushed by hand, the labor intensity is high; because of the small size, the ash storage space is smaller, and the one-time operation cycle is also smaller. The cleaning efficiency is low. The dust collection ports of the other two models are fixed, which is difficult to adapt to uneven road surfaces.
