Technical Field

The invention relates to a fresh air purification device.

Background

Along with the modernization degree of the society, the production and life style of people are changed greatly, the time of work, life and activities of people in a room is longer and longer, the activities of work, entertainment, sports and the like can be carried out indoors, and according to statistics, more than 80% of the time of people in average each day is spent indoors, so that the indoor air quality has a vital influence on the human health.

At present, a fresh air ventilator for replacing fresh air is arranged on the market, when the fresh air ventilator works, outdoor air enters the ventilator from an outdoor air inlet, then impurities in the outside air are removed sequentially through a primary filter screen, a secondary filter screen and an electrostatic precipitation box, meanwhile, indoor air enters the ventilator from an indoor air inlet, heat of the indoor air is exchanged into new air entering from the outdoor through a heat exchanger, then the new air enters the indoor after being further processed, and old indoor air is discharged to the outdoor. Although, above-mentioned fresh air ventilator can effectively purify indoor air, however, the ventilator uses the back for a long time, and the easy bonding of dust granule after the filtration is on just imitating filter screen, well effect filter screen and electrostatic precipitator case, makes its jam, and then leads to the filtration effect not good.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a fresh air purification device with simple structure and good air filtration effect aiming at the current situation of the prior art.

The technical scheme adopted by the invention for solving the technical problems is as follows: this new trend purifier, including the casing, the casing has new trend import and new trend export, its characterized in that: casing internally mounted has primary filter screen, high efficiency filter screen, dust remover, dust arrester and fan, primary filter screen and high efficiency filter screen set gradually in the wind channel between new trend import and the fan air intake, the dust remover is used for cleaing away and is attached to dust on the primary filter screen, and the dust after cleaing away is collected the dust arrester in, the air outlet of fan with the new trend export is linked together.

The primary filter screen can make a round trip to rotate under actuating mechanism's drive, the dust remover contacts with the surface of primary filter screen all the time, and the primary filter screen can drive the dust remover synchronous rotation.

As a preferred scheme, actuating mechanism is including installing motor, first sleeve, second sleeve, back shaft and the axis of rotation in the casing, first sleeve, second sleeve, back shaft and axis of rotation axial direction parallel arrangement, motor drive first sleeve rotates, and the two of primary filter screen are walked around respectively axis of rotation and back shaft, and convolute respectively first sleeve and second sleeve on, the dust remover include the pivot and install the epaxial cleaning brush in pivot, the pivot is close to the axis of rotation and parallels with the axis of rotation, the axis of rotation drives the pivot and rotates, the cleaning brush all the time with the primary filter screen contacts. Thus, the primary filter screen can be moved back and forth between the first sleeve and the second sleeve so that the cleaning brush can clean the entire filter screen.

Further preferably, the second sleeve is located the top of first sleeve, and first sleeve and second sleeve are close to the new trend import, the back shaft is the top of axis of rotation, and back shaft and axis of rotation are close to high-efficient filter screen.

In order to enable the rotating speed of the rotating shaft to be larger than that of the rotating shaft, a gear accelerating mechanism which enables the rotating speed of the rotating shaft to be larger than that of the rotating shaft is arranged between the rotating shaft and the rotating shaft.

The dust collector may have various structures, and preferably, the dust collector is a dirt collection box located directly below the cleaning brush.

More preferably, the motor is a speed reduction motor.

Preferably, the rotating shaft is a driven shaft which synchronously rotates under the driving of the primary filter screen. The primary filter screen is tightly matched with the rotating shaft, so that the primary filter screen can drive the rotating shaft to rotate when moving.

As another preferable mode, the driving mechanism includes a speed reduction motor, a first support shaft, a second support shaft and a third support shaft, the output shaft of the speed reducing motor is coaxially arranged with the first support shaft, the second bearing shaft and the third support shaft, the primary filter screen is enclosed on the output shaft of the speed reducing motor, the first support shaft, the second support shaft and the third support shaft and is driven by the speed reducing motor to rotate, the primary filter screen forms a first filter surface and a second filter surface which are oppositely arranged, the first filter surface is close to the fresh air inlet, the second filtering surface is close to the high-efficiency filtering net, the dust remover comprises a rotating shaft and a cleaning brush arranged on the rotating shaft, the pivot is close to first supporting shaft and parallels with first supporting shaft, first supporting shaft drives the pivot and rotates, the cleaning brush all the time with the primary filter screen contacts. Like this, can form the bipolar filtration of primary filter screen, promote the filter effect greatly.

Further preferably, the fan is a centrifugal fan.

In order to make the fresh air entering the inside of the casing flow more smoothly, the air inlet of the fan faces the fresh air inlet, and the air outlet of the fan faces the fresh air outlet.

Compared with the prior art, the invention has the advantages that: this new trend purifier's primary filter screen and high efficiency filter screen set gradually in the wind channel between new trend import and fan air intake, and the dust of adhering to on the primary filter screen can be clear away through the dust remover, and the dust after cleaing away is collected in the dust arrester for also can remain the filter screen throughout clean after purifier permanent work, and then improve the filtration effect, also do benefit to the life of extension filter screen simultaneously.
