Air cleaning unit, refer to and can adsorb, decompose or transform various air pollutants, comprise dust, peculiar smell etc., the product of effective raising air cleanliness, along with the raising of people's quality of life, increasing family brings into use air cleaning unit, the indoor especially after finishing and the more office of personnel, air-conditioned room.
Existing air purifier is mostly filtering type air purifier, also a class is had to be electrostatic precipitation formula air purifier, it is the fume that the principle utilizing high-pressure electrostatic to adsorb removes in air, its advantage: system is under clean situation, can the suspended particulates of filtering, efficiency can reach 85-95%, does not need to change filter screen, and air filter net amount still can.Its shortcoming: if when the integrated chamber surface of this air purifier starts accumulation particulate, filtering effects can significantly reduce fast, need often to maintain.When circuit board is dirty, can send crack sound, easily damage, this filter type can produce ozone, irritant to human body respiration organ.
Through looking into, the existing patent No. is the Chinese utility model patent " a kind of air purifier " of CN201320412978.X, it comprises housing, high-pressure electrostatic absorbing unit and preposition ionization module, it is characterized in that described preposition ionization module structure arranges two serrated metal sheets in the anterior locations left and right sides in air channel, and positive direct-current high pressure is accessed on serrated metal sheet, the positive direct-current High voltage output of high pressure generator connects two serrated metal sheets, thus arranges an electrostatic ionized field; Or preposition ionization module structure arranges carbon brush in the anterior locations in air channel, what follow carbon brush closely is a circle steel ring, the positive direct-current High voltage output of high pressure generator connects carbon brush, steel ring ground connection, thus between carbon brush and steel ring, forming arc electrostatic ionized field, described high pressure generator adopts voltage to export as KV level, electric current output are the high pressure generator of uA level.This air purifier can make the burst size of ozone be controlled in extremely low almost negligible scope, thus do not need ozone module, simplify the structure, but its ionization module is preposition, carbon brush is mounted in air inlet position, forms arc electrostatic ionized field between carbon brush and steel ring, and such benefit is the particle that can make full use of at air inlet in ionized air, but its defect is to be with a particles aggregate on blower fan in a large number, electrostatic is likely broken the risk of blower fan wiring board.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple and reasonable, safe and reliable air purifier for the above-mentioned state of the art.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of air purifier, it comprises the housing with air inlet and air outlet, be arranged on the blower fan in housing and high-pressure electrostatic absorbing unit, wherein air inlet is positioned at the rear side of housing, air outlet is positioned at the front side of housing, it is characterized in that: the position that the front side of described housing is positioned at air outlet is provided with a negative ion emission head, and this negative ion emission head is connected with the circuit output end of negative ion device.
As improvement, described high-pressure electrostatic absorbing unit is after the superposition of control of dust metallic plate space crossings, odd-level control of dust metallic plate is connected in parallel at left-end point and connects, form first input end, even level control of dust metallic plate at right end and downlink connection get up, form the second input, first input end, the second input access positive direct-current high pressure, negative dc high voltage or ground connection respectively, thus are forming parallel electrostatic field between control of dust metallic plate layer by layer.
As improvement, the positive direct-current high-voltage output end of described high pressure generator is connected with the first input end of high-pressure electrostatic absorbing unit, and negative dc high voltage output or ground connection are connected with the second input of high-pressure electrostatic absorbing unit.
Improve, described blower fan is two DC fans again, and go to upper and lower the one end be arranged near air outlet in housing respectively, high-pressure electrostatic absorbing unit is arranged on the rear portion of blower fan near the position of housing air inlet.
Finally, described negative ion emission head adopts rectangular metallic plate.
Compared with prior art, the utility model has the advantage of: air outlet position negative ion emission head being arranged on housing, eliminate the carbon brush in original ionization module and steel ring, avoid original ionization module preposition in air inlet, likely cause the risk that blower fan wiring board is broken by high pressure, not only make structure advantages of simple more, and use also more safe and reliable, in addition, anion can exist several minutes in atmosphere, make with fresh air, good purification, make negative electrical charge on the Interior Space band of gas simultaneously, fallen by the absorption of high-pressure electrostatic absorbing unit, structure is more rationally reliable.
Accompanying drawing explanation
Fig. 1 is the air purifier structural representation before improving;
Fig. 2 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, for the air purifier before improvement, the i.e. air purifier of patent No. 201320412978.X, can see, this air purifier comprises housing 1, high-pressure electrostatic absorbing unit 3 and preposition ionization module 4, preposition ionization module 4 arranges carbon brush 4.3 in the anterior locations in air channel, what follow carbon brush 4.3 closely is a circle steel ring 4.4, the positive direct-current High voltage output of high pressure generator connects carbon brush 4.3, steel ring 4.4 ground connection, thus between carbon brush 4.3 and steel ring 4.4, form arc electrostatic ionized field, described high pressure generator adopts voltage to export as KV level, electric current exports the high pressure generator for uA level.
