Abstract

The utility model discloses a dust collector with a novel dust cup, which at least comprises a cup body and a filtration stand, wherein the cup body is internally provided with an accommodating cavity; the filtration stand is arranged on the cup body in a detachable mode; the cup body comprises a cyclone chamber positioned at the center of the accommodating cavity and a dust collecting chamber surrounding the cyclone chamber; and the upper end of the cyclone chamber is open and is communicated with the dust collecting chamber. In the utility model, the upper end of the cyclone chamber is open and the cup body is directly sealed by the filtration stand to prevent dust from flowing back into the cyclone chamber, so that the cyclone separation effect is improved. Moreover, the dust collector has a simple structure, and meanwhile, a filtering part is avoided being missed.

Description

Dust catcher with novel dirt cup

Technical field

the utility model relates to a kind of dust catcher with novel dirt cup.

Background technology

existing dust catcher comprises body, be positioned at the dirt cup of body top, and this dirt cup generally includes dust storage chamber and the cyclone chamber adjacent with dust storage chamber, and cyclone chamber generally include a detachable filtering screen, be connected with dust storage chamber get rid of the ash mouth; Because it is too small to get rid of grey open area, and dust storage chamber only is positioned at cyclone chamber one side, can't fully increase the control of dust volume of dust storage chamber; Cause cyclone effect not good thus, and the user needs the cleaning of frequent ash, and the user is in scale removal process; Often filtering screen is taken off; And forget again and load onto, might cause extra large handkerchief directly to be blocked, influence dust catcher work.

Summary of the invention

the utility model purpose is: a kind of simple in structure, dust catcher with novel dirt cup is provided.

The technical scheme of the utility model is: a kind of dust catcher with novel dirt cup; The cup of one host cavity is arranged in it comprises at least and be releasably attached to the filtering frame on the cup; Wherein cup comprises the cyclone chamber that is positioned at the host cavity center, the dust storage chamber that centers on cyclone chamber, and this cyclone chamber upper end is opened and is interconnected with dust storage chamber.

On the basis of technique scheme, further comprise following attached technical scheme:

said cyclone chamber comprises a cyclonic chamber, be positioned at an annular sidewall in the cyclonic chamber outside and be set on the annular sidewall and exntension tubs that the upper end is open.

It further comprises inner cover that is positioned at filter top and fastens the dirt bowl cover with fixed filter unit each other with filtering frame.

said cyclone chamber further comprises the spiral guide portion that is positioned at the bottom and is positioned at the center and upwardly extending protuberance that wherein protuberance stretches in the exntension tubs.

said filtering frame is one-body molded, and it comprise hollow channel that the filter house that is positioned at bottom centre, an end and filter house be communicated with, link to each other and accommodate with the other end of hollow channel filter containing cavity, be positioned at the ring outer wall outside the containing cavity.

said filter house has several filtering holes and extending in the cyclonic chamber of cyclone chamber downwards, and this hollow channel is along with airflow direction becomes big, and the upper end of the bottom of outer wall and cup fastens and seals.

The utility model advantage is:

the utility model is because cyclone chamber upper end is open, and directly seals cup through filtering frame, prevents that dust is back in the cyclone chamber again, improves the cyclonic separation effect thus, and simple in structure, avoids the neglected loading filter house simultaneously.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the decomposing schematic representation of the utility model;

Fig. 2 is the assembling cross-sectional schematic of the utility model;

wherein: 10, cup; 12, cyclone chamber; 14, dust storage chamber; 20, filtering frame; 30, filter; 40, inner cover; 50, dirt bowl cover; 100, host cavity; 120, cyclonic chamber; 122, annular sidewall; 124, exntension tubs; 126, spiral guide portion; 128, protuberance; 200, filter house; 202, hollow channel; 204, containing cavity; 206, outer wall.

The specific embodiment

embodiment: shown in Fig. 1-2, the utility model provides a kind of specific embodiment with dust catcher of novel dirt cup, it comprise have vacuum motor (not shown) body (not shown), be positioned at the dirt cup on the body.This dirt cup is cylinder type, have in it comprises a host cavity 100 cup 10, be releasably attached to filtering frame 20 on the cup 10, be placed to filter 30 on the filtering frame 20, be positioned at the inner cover 40 of filter 30 tops and fasten dirt bowl covers 50 each other with fixed filter unit 30 with filtering frame 20.Wherein inner cover 40 and filter 30 each other against, with location filter 30 and the air-out passage is provided, inner cover 40 is removable element in the present embodiment, also can be one-body molded with dirt bowl cover 50.

cup 10 comprises the cyclone chamber 12 that is positioned at host cavity 100 centers, the dust storage chamber 14 that centers on cyclone chamber 12.Wherein cyclone chamber 12 comprise a cyclonic chamber 120, be positioned at cyclonic chamber 120 outsides an annular sidewall 122, be set on the annular sidewall 122 and the upper end is open exntension tubs 124, be positioned at the spiral guide portion 126 of bottom and be positioned at the center and upwardly extending protuberance 128.Wherein protuberance 128 stretches into exntension tubs 124 inside, and spiral guide portion 126 is then in annular sidewall 122 and do not stretch in the exntension tubs 124.

filtering frame 20 is one-body molded, and it comprise hollow channel 202 that the filter house 200 that is positioned at bottom centre, an end and filter house 200 be communicated with, link to each other and accommodate with the other end of hollow channel 202 filter 30 containing cavity 204, be positioned at the ring outer wall 206 in containing cavity 204 outsides.Wherein hollow channel 202 is along with airflow direction becomes big.Filter house 200 has several filtering holes, to filter dust-contained airflow.During assembling, the upper end of the bottom of outer wall 206 and cup 10 fastens sealing, and filter house 200 extend into downwards in the cyclonic chamber 120 of cyclone chamber 12.
