Abstract

The utility model relates to a cyclone filter for a dust collection barrel of a dust collector, which comprises the dust collection barrel. A dust collection barrel cover is mounted at an opening at the upper part of the dust collection barrel; an air inlet is formed on the dust collection barrel cover; an air guide cover is mounted inside the dust collection barrel cover; a helical air inlet channel and an air outlet channel are respectively arranged on the air guide cover; a filter is arranged in the air guide cover; one end of the helical air inlet channel is connected with the air inlet of the dust collection barrel cover, and the other end thereof is communicated with the inner cavity of the dust collection barrel; one end of the air outlet channel is connected with the inner cavity of the dust collection barrel, and the other end thereof is communicated with the filter; the filter is connected with an air outlet pipe; and the air outlet of the air outlet pipe extends to the bottom part of the dust collection barrel. The cyclone filter has the advantages of simple and reasonable structure, optimal refuse and dust particle separation and filtration effects, convenient assembly and disassembly and convenient cleaning and maintenance. In addition, because the HEPA filter is covered with the air guide cover, the used dirty HEPA filter can not be seen from the outside of the dust collection barrel, so that the visual effect is enhanced.

Technical field

The utility model relates to the dust catcher technical field, especially a kind of cyclonic filter device of dust collecting bucket of dust catcher.

Background technology

Existing whirlwind class dust catcher can be equipped with the cyclonic filter device on dust bucket, so that the rubbish of the mixed airflow that will pass through and grit etc. separate out, and be collected in the dust bucket; And existing cyclonic filter device, its structure and a great variety of models, but all have the following disadvantages: (1) its complex structure, and the poor effect of separating and filtering, and install and remove loaded down with trivial detailsly, bring inconvenience for cleaning and maintenance; (2) existing whirlwind class vacuum cleaner is understood the dust bucket that be provided for collecting grit in casing, after the dirt in the dust bucket amasss completely, need open the dirt bung at dust bucket top earlier, take out cyclonic filter mechanism again after, just can pour out the bucket in a laying dust, therefore, the operation of falling dirt is extremely inconvenient.

The utility model content

The purpose of this utility model is to overcome above-mentioned existing in prior technology deficiency, and provides a kind of simple and reasonable for structure, and rubbish separates with grit etc. and the cyclonic filter device of the vacuum cleaner dust bucket that the effect of filtering is splendid.

The utility model purpose is achieved in that

The cyclonic filter device of vacuum cleaner dust bucket, comprise dust bucket, the upper opening of dust bucket is equipped with the dirt bung, offer air inlet on the described dirt bung, the inside of dirt bung is equipped with wind scooper, be respectively arranged with spiral air intake passage and air-out passage on the wind scooper, be provided with filter in the wind scooper, spiral air intake passage one end connects dirt bung air inlet, the other end and the conducting of dust bucket inner chamber, air-out passage one end links to each other with the dust bucket inner chamber, and the other end is communicated with filter, described filter is connected with discharge pipe, and the air outlet of discharge pipe extends to the dust bucket bottom.

The utility model can also adopt following technical measures to solve:

Described filter is the HEPA high efficiency particle air filter.

Described wind scooper comprises spiral part and central ventilating duct part thereof, spiral part is made of detachable upper and lower shaped spiral housing, central authorities' ventilating duct partly is the center through hole by spiral part, and extend the extension cylindrical shell that constitutes hollow downwards by this through hole and form, the annular break joint between central ventilating duct and the filter constitutes wind scooper air-out passage.

Described dirt bung spiral is at transparent dirt bucket upper opening, and wind scooper is connected the inner cap central authorities of dirt bung.

The bottom opening of described dust bucket is equipped with bottom, and the bottom opening of bottom one end and dust bucket is hinged, is provided with bottom between the bottom opening of the other end and dust bucket and opens button.

Described bottom is opened button and is installed on the sidewall axis hole of dust bucket bottom opening in the mode that axle rotates, and bottom is opened button and made fulcrum with this axis hole, and the bottom that bottom is opened button withholds bottom.

The beneficial effects of the utility model are:

(1) the cyclonic filter device of dust collecting bucket of dust catcher of the present utility model, the spiral air intake passage of mixed airflow on the dirt bung enters the dust bucket inner chamber, and formation swirling eddy, big rubbish and cinder dirt is separated falls at the bottom of the dirt bucket under action of centrifugal force, the thin dusts that are not separated etc. filter through filter with air-flow, at last, air-flow can be derived from the air outlet of discharge pipe, whole separation and filter effect are splendid, and it is simple in structure, rationally, and HEPA cleaning, it is convenient to change, Unscrew dirt bung, rotate airduct and can take out HEPA, therefore, convenient mounting or dismounting provide convenience for cleaning and maintenance; Have again, encase, outside dust bucket, can't see used dirty HEPA filter, strengthen visual effect because the HEPA filter is directed to cover;

(2) this kind of vacuum cleaner dust bucket, owing to be provided with the bottom device for opening, by bottom the bottom that can be opened is set at dust bucket, so that need not to open dirt bung and cyclonic filter cross mechanism also can the operation of falling dirt, and total is simple, reasonable, the opening operation of bottom is simple and easy, convenient dirt.

The specific embodiment

Extremely shown in Figure 5 as Fig. 1, a kind of cyclonic filter device of dust collecting bucket of dust catcher, comprise dust bucket 1, the upper opening of dust bucket 1 is equipped with dirt bung 2, offer air inlet 3 on the described dirt bung 2, the inside of dirt bung 2 is equipped with wind scooper 4, be respectively arranged with spiral air intake passage 5 and air-out passage 6 on the wind scooper 4, be provided with HEPA high efficiency particle air filter 7 in the wind scooper 4, spiral air intake passage 5 one ends connect dirt bung air inlet 3, the other end and dust bucket 1 inner chamber conducting, air-out passage 6 one ends link to each other with dust bucket 1 inner chamber, the other end is communicated with filter 7, and described filter 7 is connected with discharge pipe 8, and the air outlet of discharge pipe 8 extends to dust bucket 1 bottom.
