Description
Technical field
The utility model relates to cleaner field more particularly to a kind of air channel structures of dust catcher.
Background technique
With the rapid development and continuous improvement of people's living standards of small household appliance technology, dust catcher is had become as people
One of daily life field indispensability electric appliance.
Currently, dust catcher in the market, air channel structure is complicated, air duct filter effect is poor, and then causes close to blower
The protection filter screen at place is easily contaminated, and the protection filter screen replacement at blower is more difficult, brings to user
It is greatly inconvenient, it is badly in need of solving as a result,.
Utility model content
The purpose of this utility model is that in view of the above-mentioned problems, provide a kind of air channel structure of dust catcher, it is existing to solve
The problem of air channel structure of dust catcher is complicated, poor filtration effect.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of air channel structure of dust catcher, including air duct ontology, the air duct ontology include blast pipe and with blast pipe phase
Filtering air duct even, described filter are provided with one cyclonic cover, the one cyclonic at the air outlet for being located at blast pipe in air duct
One end of cover is connected with more struts, and the more struts are along the circumferential direction uniformly distributed, and gap is provided between adjacent struts,
One end of the strut is connected with one cyclonic cover, and the other end is sealedly connected with fixing seat, and level-one mistake is equipped on strut
Strainer is provided with second level whirlwind cone, dirt barrel in the one cyclonic cover, is provided with second level at the outlet air end of the second level whirlwind cone
Filter screen, and second level whirlwind cone is located at the opening of dirt barrel.
As a kind of preferred embodiment of the utility model, one is provided at the one cyclonic cover face blast pipe air outlet
Guiding surface.
As a kind of preferred embodiment of the utility model, the strut is 6, along the circumferential direction uniformly distributed.
As a kind of preferred embodiment of the utility model, 6 struts are structure as a whole with one cyclonic cover.
As a kind of preferred embodiment of the utility model, the air inlet of the blast pipe is provided with leading for an inclination arrangement
Enter face.
The beneficial effects of the utility model are, a kind of air channel structure of dust catcher has the characteristics that structure is simple, and
It uses secondary filtration, effectively increases filter effect, so as to extend at blower the service life for protecting filter screen, subtracts
Few maintenance times.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the air channel structure of dust catcher of the utility model；
Fig. 2 is the schematic diagram of internal structure that the utility model filters air duct.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.It can manage
Solution, embodiment described herein are used only for explaining the utility model, rather than the restriction to the utility model.
It please refers to shown in Fig. 1 and Fig. 2, in this present embodiment, a kind of air channel structure of dust catcher, including air duct ontology, institute
Stating air duct ontology includes blast pipe 1 and the filtering air duct 2 being connected with blast pipe 1, and the air inlet of the blast pipe 1 is provided with one
The approaching face 3 of inclination arrangement, the filtering air duct 2 is interior to be provided with one cyclonic cover 4 at the air outlet of blast pipe 1, described
It is provided with a guiding surface 9 at 4 face blast pipe of one cyclonic cover, 1 air outlet, and the left end of one cyclonic cover 4 is connected with 6
Strut, 6 struts are along the circumferential direction uniformly distributed, and gap is provided between adjacent struts, 6 struts and level-one
Whirlwind cover 4 is structure as a whole, and the right end of the strut is connected with one cyclonic cover 4, and left end is sealedly connected with fixing seat 8, and
Primary filter 5 is installed on strut, second level whirlwind is provided in the one cyclonic cover 4 and bores 6, dirt barrel 7, the second level whirlwind
Secondary filter is provided at the outlet air end of cone 6, and second level whirlwind cone 6 is located at the opening of dirt barrel 7.
Air is entered by the air inlet of blast pipe 1, then enters filtering air duct 2 by the air outlet outflow of blast pipe 1, first
By the guiding surface 9 of one cyclonic cover 4, under the action of guiding surface 9, along 4 rotating separation of one cyclonic cover, play certain
Get rid of grey effect, then, air by primary filter 5 enter one cyclonic cover 4 inside, large particle by primary filter gear exists
Outside falls into bottom, and the air flowed into inside one cyclonic cover 4 further gets rid of particulate matter under the action of second level whirlwind cone 6
It separates out, and falls into dirt barrel 7, surplus air continues to flow, and is filtered through secondary filter；By using two layers of filtering side
Formula is thrown away most of dust using physical structure, and the service life of the protection strainer at blower can be made to prolong significantly
It is long.
Above embodiments only elaborate the basic principles and features of the present invention, and the utility model is not by above-mentioned implementation
Example limitation, on the premise of not departing from the spirit and scope of the utility model, the present invention has various changes and changes, these
Changes and modifications are fallen within the scope of the claimed invention.The utility model requires protection scope is by appended right
Claim defines.
