Abstract

The utility model relates to a dust filter, comprising a cyclone filter and a centrifugal fan, wherein an air outlet of the cyclone filter is communicated with an exhaust inlet of the centrifugal fan; the centrifugal fan generates air negative pressure when working; the air with dust is absorbed into the cyclone filter; most of large dust particles are firstly thrown to an ash storage chamber after the dust enters a spiral channel of the cyclone filter because of centrifugal effect of the spiral channel; and the air absorbed into the centrifugal fan is primarily purified, so as to achieve the dust removal effect. By adopting the dust filter, the dust filtering effect of the air can be improved; environmental protection is facilitated; cleaning of a user is facilitated; and the service life is also prolonged.

Description

A kind of dust filter
Technical field
The utility model belongs to the cleaner field, particularly a kind of dust filter.
Background technology
Deduster generally all is to filter dust by traditional cloth bag or paper bag now, and the screen pack that passes through that also has filters dust.The screen pack of existing deduster generally all is located at dust-storage chamber.Because the air process deduster air inlet that has dust just enters into the screen pack of dust-storage chamber, has strengthened the burden of screen pack like this, the screen pack so the dust that gathers is very easily made dirty then cleans to the user and also makes troubles, and shortened the service life of screen pack.The bulky grain dust enters before the screen pack also without any processing, so very easily stops up screen pack.
The utility model content
Technical problem to be solved in the utility model is, a kind of dust arrester that does not need dirt bag, filter paper and filter core is provided, and does not worry that screen pack is in use owing to the accumulation of dust causes passage to stop up.
The utility model is to realize like this, a kind of dust filter is provided, comprise cyclone filter and centrifugal blower, cyclone filter comprises air inlet, air outlet, rotating room and Dust Storage Room, centrifugal blower is provided with inlet scoop and blowing mouth, and the air outlet of cyclone filter is connected with the inlet scoop of centrifugal blower, and air inlet is arranged on a side of rotating room, air outlet is arranged on the opposite side of rotating room, and Dust Storage Room is arranged on the bottom of rotating room; Be provided with helical duct in the rotating room, the front end of helical duct communicates with air inlet, and its rear end communicates with Dust Storage Room.
Further, the rotating room comprises inside and outside two pipes that arrange, and helical duct is arranged between two pipes, and the front end of helical duct is provided with spiral planar; The front end of interior pipe communicates with air outlet, and its rear end is provided with some blend stops; The tail end of helical duct is near the rear end of interior pipe.
Further, air inlet is arranged on the front end of outer pipe, and communicates with the front end of helical duct.
Further, the rear end of pipe is provided with breach outside, and breach communicates with Dust Storage Room.
Further, be provided with shell and baffle plate in the outside of rotating room, baffle plate is used for the rear end of the outer pipe of sealing.
Further, be provided with cleaning door in the lower end of Dust Storage Room, cleaning door is provided with removable plug.
Compared with prior art, dust filter of the present utility model comprises cyclone filter and centrifugal blower, and the air outlet of cyclone filter is connected with the inlet scoop of centrifugal blower.Produce air negative pressure during centrifugal blower work, the air that has dust is sucked in the cyclone filter.Dust enters after the helical duct of cyclone filter, because the centrifugal action of helical duct, the big dust granules of the overwhelming majority are thrown toward Dust Storage Room earlier, preliminary purification the air of inspiration centrifugal blower, reach dust removing effects.The utility model can improve the filter dirt effect of air, is conducive to environmental protection, makes things convenient for the user to clean again, also prolongs its service life.
Description of drawings
Fig. 1 is the schematic perspective view of preferred embodiment of the present utility model;
Fig. 2 is the decomposing schematic representation of cyclone filter among Fig. 1.
The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Please refer to Figure 1 and Figure 2, the dust filter of the utility model preferred embodiment comprises cyclone filter 1 and centrifugal blower 2.Cyclone filter 1 comprises air inlet 11, air outlet 12, rotating room 13 and Dust Storage Room 14, and centrifugal blower 2 is provided with inlet scoop 21 and blowing mouth 22, and the air outlet 12 of cyclone filter 1 is connected with the inlet scoop 21 of centrifugal blower 2.
Air inlet 11 is arranged on a side of rotating room 13, and air outlet 12 is arranged on the opposite side of rotating room 13, and in the present embodiment, air inlet 11 is arranged on the front portion 131 of rotating room 13, and air outlet 12 is arranged on the right side 132 of rotating room 13.Dust Storage Room 14 is arranged on the bottom 133 of rotating room 13, is convenient to collect dust.Be provided with helical duct 134 in rotating room 13, the front end 1341 of helical duct 134 communicates with air inlet 11, and its rear end 1342 communicates with Dust Storage Room 14.Rotating room 13 comprises inside and outside two pipes 135 that arrange and 136, and helical duct 134 is arranged between two pipes 135 and 136.The front end 1341 of helical duct 134 is provided with spiral planar 137.The front end 1351 of interior pipe 135 communicates with air outlet 12, and its rear end 1352 is provided with some blend stops 138, prevents that big dust granule from entering in the centrifugal blower 2 from interior pipe 135.The tail end 1342 of helical duct 134 is near the rear end 1352 of interior pipe 135.Air inlet 11 is arranged on the front end 1361 of outer pipe 136, and communicates with the front end 1341 of helical duct 134.The rear end 1362 of pipe 136 is provided with breach 1363 outside, and breach 1363 communicates with Dust Storage Room 14.The air that contains dust rotates in helical duct 134 and produces centrifugal action, makes big dust granule move along the inwall of outer pipe 136 rapidly, and fall into Dust Storage Room 14 from breach 1363.
13 outside is provided with shell 15 and baffle plate 16 in the rotating room, and baffle plate 16 is used for the rear end 1362 of the outer pipe 136 of sealing.Be provided with cleaning door 17 in the lower end of Dust Storage Room 14, the dust of Dust Storage Room 14 can be discharged via cleaning door 17.Cleaning door 17 is provided with removable plug 18, is convenient to discharge the dust in the Dust Storage Room 14.In the present embodiment, plug 18 is nut.Turn on nut, just can discharge the dust of Dust Storage Room 14; Turn round top nut, just can allow Dust Storage Room 14 continue to store dust.
The operation principle of present embodiment is: centrifugal blower 2 provides power, the air-flow that has dust is walked in rotating room 13, because helical duct 134 is spiral-shaped, thereby make the miscarriage of high speed rotary air give birth to centrifugal benefit, dust in air breach 1363 from outer pipe 136 inwalls under centrifugal action flies to the Dust Storage Room 14, thereby removed the dust in the air-flow, the air stream after the dedusting cleaning is discharged by centrifugal blower 2.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
