Description

A kind of dust catcher

【Technical field】

It the utility model is related to a kind of dust catcher.

【Background technology】

Dust catcher is conventional household cleaning equipment, possesses the function of separating dust and chip from air, generally Including head, dust barrel and hasp, head is releasably installed together with dust barrel by hasp, is provided with motor in head, is used for As power source formed dust suction air-flow, motor work when can generate heat, handpiece case is often provided with passage so that shell it is interior Portion is unlikely to overheat, and the utility model provides the dust catcher after a kind of improvement based on existing dust catcher.

【Utility model content】

Problem to be solved in the utility model is to provide one kind and hides perforate using accepting groove inwall apertured, with certain Effect, Housing failure risk reduce dust catcher.

In order to solve the above technical problems, the utility model adopts the following technical scheme that：A kind of dust catcher, including head, dirt Bucket and hasp, hasp are located on the outside of dust catcher, and head is releasably installed together with dust barrel by hasp, and electricity is provided with head Machine, head are additionally provided with shell, and the shell is provided with the first relative sidepiece and the second sidepiece, is connected the first sidepiece and the second sidepiece Basal wall, the first sidepiece, the second sidepiece and basal wall surround the first accepting groove to shell indent, and basal wall is provided with some insertions first The passage of accepting groove and enclosure, the fastener section, which is contained in first accepting groove and is provided with, faces the passage Mainboard, basal wall is relative with mainboard interval.

For the utility model, basal wall is located at basal wall and hasp master equivalent to one inwall of the first accepting groove, passage Plate face is more fully effectively utilized the inwall apertured of accepting groove, reduced in the other relatively more exposed of shell to passage Position apertured；For basal wall because orificing strength can weaken, the first sidepiece, the second sidepiece, mainboard produce certain hiding ventilation , can also be to the protective action of blocking of basal wall while the effect in hole, the risk that the basal wall of apertured is damaged by external impacts reduces.
