Description

A kind of blast air filter

Technical field

The present invention relates to technical field of air purification, particularly relate to a kind of blast air filter.

Background technology

Air filter refers to air filter, is generally used for dust proof workshop, clean room, clean operating room, experiment Room and toilet, or dust-proof for electric mechanical communication equipment etc..Air filter is widely used in oil, chemical industry, metallurgy, electricity Power, machinery, light industry, weaving, automobile making, electronics, food, medicine, biochemistry, national defence, scientific research etc. need compressed air purifying Other industry and department.

Particulate in air remove the filtration of technology predominantly organic tool, absorption, electrostatic precipitation, anion and plasma method and Electrostatic electret filtration etc..Absorption is high surface area and the loose structure capture particulate pollutant utilizing material, it is easy to blocking, uses More notable in gas pollutant removal effect；Electrostatic precipitation is to utilize high-voltage electrostatic field to make gas ionization so that dust particles is inhaled The collecting method being attached on electrode, though its windage is little but traps weak effect to larger particles and fiber, can cause electric discharge, and clean Bother time-consuming, be easily generated ozone, form secondary pollution；The work that anion and plasma method remove indoor particle pollutant is former Reason is similar, is all by making the particulate matter in air charged, and coalescence forms larger particles and settles, but particulate matter is the most not Remove, be only attached on neighbouring surface, be easily caused airborne dust again.

This case needs emphasis to refer to existing air filter mask, mainly allows air to flow in filter, air In particulate matter enable a person to breathe to ozone by filtration, but this remains a lot of defect: first, air stream Dynamic property is poor, makes people when wearing masks, dyspnea often occurs；Secondly, when air is flowed into filter interior, can be subject to To the impact of battery, the air quality after impact filtration；Meanwhile, current all of air filter is both for the environment of surrounding Tell on, lack the device that the cleaned air after purifying directly conducts.

Therefore, for the above, need prior art is reasonably improved.

Summary of the invention

For disadvantages described above, the present invention provides one can accelerate air flowing, cannot independently will not exhale because of dyspnea Inhale, do not affect filtration after air quality, be easy to regulation, be conducive to provide the blast air filter of healthy air, to solve Certainly many deficiencies of prior art.

For achieving the above object, the present invention is by the following technical solutions:

A kind of blast air filter, is made up of cover, filter element, wind deflector, circuit board, aerator, drain pan, described Fixing bottom lid and connect drain pan and form an inner cavity chamber, cover surrounding is respectively provided with some pores, and this inner cavity chamber is internal solid Dingan County dress filter element and the upper and lower both sides of this filter element be respectively provided with sealing member I, sealing member II successively, filter element periphery be provided with some carefully Little through hole；Described drain pan inboard is fixing sets up one piece of wind deflector and this wind deflector top edge arranges a circle sealing member III, institute Fixedly mount battery compartment in stating the cavity between filter element and wind deflector and this battery compartment is fixed on by upper cover and lower cover group In the battery compartment become, set up electro-heat equipment above this wind deflector and between lower cover and this electro-heat equipment is peripheral with fin； Described wind deflector surface is with two fixing holes, and circular port therein fixed installation aerator, rectangular opening therein fixedly mounts Circuit board, drain pan side configuration button.

Correspondingly, back buckle is fixedly mounted bottom described drain pan, with spring between aerator and drain pan；

Power switch button is located at outside air filter.

Having the beneficial effect that of blast air filter of the present invention

(1) it is applicable to air filter mask completely, by arranging aerator in the filter, aerator actively send Wind and accelerate the flowing of air, make people when wearing masks, will not can not autonomous respiration because of dyspnea；

(2) aerator passes through lithium battery power supply, and lithium battery is placed in cell cover and battery lower cover, close by sealing member Envelope, when air is flowed into filter interior, will not be affected by battery, not interfered with the air quality after filtration；

(3) filter element four limit is provided with multiple tiny through hole, the fine particle thing in the air filtering excessively of energy multi-angle, permissible Blow without dead angle for 360 °；

(4) power switch button is located at outside air filter, can control different gears easily, can adjust aerator The speed of air-supply；

(5) by being provided with electro-heat equipment in inside, in the case of ambient temperature is relatively low, heating function can be used, to mistake The air heating of filter, the air breathing heating is more comfortable to human body.
