Bacteria collected by the two sets of electric fields can be almost killed for 100 percents; the dust removing efficiency reaches 95 percents. Therefore, the purpose of sterilizing, disinfecting, removing dust and removing peculiar smell of the indoor air is realized to realize the improvement of the air quality with high efficiency.

Description

The electrostatic sterilization air cleaner

The utility model relates to a kind of electrostatic sterilization air cleaner, particularly a kind of earning of air machine with kill bacteria, electrostatic precipitation.

As everyone knows, air cleaner in the market mainly contains three kinds of forms: the one, and filtering type, the 2nd, anion generator, the 3rd, electrostatic precipitation adds the combined type of filtering earning.People are common to think that the air cleaning performance of the third form is best.The key of electrostatic precipitation is a field generator, the patented product of existing air cleaner (patent No. 93226519.7) adopts honeycomb needle bar shape two-region electric field structure, though honey comb like dust-collecting area maximum, but because polarized area and accumulation area are in same honeycomb, in a single day polarizing voltage increases, just puncture arcing easily, produce ozone with high concentration.If adopt circular hole needle-like polarized electric field separately, its polarizing voltage can be higher, but windage is bigger, and dust collection effect is unsatisfactory.

The purpose of this utility model provides the electrostatic sterilization air cleaner of the two electric field series-mode frames of a kind of circular hole honeycomb needle bar shape, but it has both high voltage polarizations, big specific collection area is arranged, the characteristics that windage is minimum again.

The utility model is to realize like this, initialization flow process as conventional earning of electrostatic sterilization air machine, air enters from air inlet in stopping up, earlier by the static prefiltering net, this static prefiltering net is made up of molybdenum filament parallel pole that adds negative high voltage static and the static aluminium foil dust-collecting net that adds positive high voltage, airborne particle, bacterium etc. are with negative electrical charge after the ionization of molybdenum filament parallel electric field mesohigh, by the absorption of the aluminum foil web of positive electrostatic field, reach pre-filtered purpose then.The air of preliminary purification enters the two electric fields of circular hole honeycomb needle bar shape efficiently subsequently.Circular hole needle-like polarized electric field with the air grit high pressure ionization of prefiltration, makes it to be with negative electrical charge earlier, enters the bar-shaped electric field of honeycomb then and is gathered dust.According to the requirement of actual working environment to cleanliness factor, the two electric fields of circular hole honeycomb needle bar shape can also have and are in series more than two or more, dust removal efficiency is reached more than 95%, dust particles such as surplus dirt, bacterium, virus are 100% kill almost, thereby realize the purpose of room air sterilization, sterilization, dedusting, removal peculiar smell, the realization high efficiency is improved air quality.

Come the utility model is further elaborated with Figure of description below.

Fig. 1 is the utility model structural representation.

Fig. 2 is the high-voltage electrostatic field that circular hole honeycomb needle bar shape electric field constitutes for the utility model.

Fig. 3 is the bar-shaped electric field plane of honeycomb for the utility model.

Fig. 4 is a circular hole needle-like electric field plane for the utility model.

Embodiment: static prefiltering net, high-pressure electrostatic electric field (6) (7), immersion-type charcoal filter (8), infrared sensing switch (9), anion generator (10) and air outlet (11) that earning of cabinet-type electrostatic sterilization air machine is mainly formed by air inlet 1, centrifuge 2, high-frequency and high-voltage Switching Power Supply (3), parallel molybdenum filament (4) and aluminum foil web (5) are formed.Wherein the structure of high-voltage electrostatic field (6) (7) is all identical, is circular hole honeycomb needle bar shape double-field structure.Fig. 2 is this electric field structure.Honeycomb plate (19) punch die forms in the bar-shaped electric field of honeycomb, discharge electrode is made up of stick electrode (17), circular hole slab (12) punch die of circular hole needle-like electric field forms, discharge electrode is made up of needle electrode (18), needle electrode (18) is fixed on the battery lead plate (20), two electric fields all are connected on the high-frequency and high-voltage Switching Power Supply (3), form the structure of two electric fields.Add negative voltage on the pole plate (13) of stick electrode (17) fixation, honeycomb plate (19) has certain thickness, on add malleation, and the grit of subsidiary negative electricity, bacterium.Circular hole slab (12) is identical with stick electrode (17) polarity of voltage, and for punch die forms, the centre has needle electrode (18) to form electric loop, adds positive voltage on the needle electrode, so that the particulate polarization effect is better in the air.In room air, be mixed with a large amount of pollutants, mainly contain meal dirt.When cigarette smoke bacterium, virus, carcinogen, toxic and harmful, opening power, room air enters from air inlet (1), arrives the electrostatic pre-filters that parallel molybdenum filament (4) and aluminum foil web (5) form, and filters out meal dirt, as hair, fiber, dust etc.Enter high-voltage electrostatic field (6) (7) then, in the series connection electric field, because the structure of circular hole needle-like, it is very high that polarizing voltage can reach, and makes air ionization and seldom produce ozone.And honey comb like dust-collecting area maximum, circular hole honeycomb club shaped structure has utilized the advantage of these two kinds of electric fields just, so just obtained both can efficiently polarizing, maximum dust suction area is arranged again, and the high-effective dust-removing sterilization electric field that windage is minimum, smog in can absorbed air, respirable dust, bacterium, virus and carcinogen, the dust suction utmost point of electric field scribbles long-acting fungicide, can kill the bacterium that is captured by electric field rapidly, virus, thus bacterium and viral gathering avoided, procreation is bordering on 100% with the bacterium that traps and kills, the wind speed that enter positive electric field this moment is 2-3m/s, average field-strength 6-8kv/cm ², enter immersion-type active carbon filter (8) then, enter anion generator (10) at last, send from the air outlet (11) on top through cleaned air passes, thereby realize air cleaning.

But the utlity model has both high voltage polarizations, big specific collection area is arranged again, good dedusting effect, the windage utmost point Little characteristics are the desirable air cleaners such as hospital, office, hotel.
