Description
Technical field
This utility model relates to plasma generator part, is specifically related to a kind of plasma generator simple in structure.
Background technology
Plasma is by the ion with positive and negative electric charge and electronics, and the aggregation that also may also have some neutral atoms and molecule to form is generally electric neutrality in macroscopic view, and plasma can be solid-state, liquid state and gaseous state.General gas flow electric discharge, will produce plasma, and this electric discharge is now as by certain mechanism, one or more electronics being separated from gas atom or molecule exactly, forms gaseous medium, and this medium is just called ionized gas.Utilize this feature of plasma can make it obtain the new application of sterilizing, purifying air.Utilize positive and negative high voltage ionized air (being mainly oxygen) to produce a large amount of positive and negative ion, and the quantity of anion be greater than cation quantity, usually, the quantity of anion is approximately 1.5 times of amount of positive ions.Produced simultaneously positive and negative ion has little time diffusion, in space, carry out positive and negative charge neutralization, and the huge energy of abrupt release, thereby kill the antibacterial in surrounding air, in addition, unnecessary negative oxygen ion can with airborne pollutant effect, contaminant molecule is decomposed within the extremely short time, and follow-up various reactions occur to reach the object of degradation of contaminant, thereby improve the quality of air.
At present, air purifier based on above-mentioned principle has appeared in people's life, as the disclosed a kind of depurator of Chinese invention patent " low-temperature plasma purifier " (application publication number CN101391171A), mainly comprise outer quartz ampoule and be wound in the stainless steel annular on outer quartz ampoule, the built-in one end of outer quartz ampoule is with copper pipe and the support component of copper splinter, the positive and negative electrode probe that is positioned at outer quartz ampoule two ends joins with copper splinter and ring like steel wire respectively, excites isoionic lamp tube structure thereby formed.But the plasma generator composed component of said structure is more, be difficult to carry out industrialization production, and, based on the structure that arranges of ring like steel wire and built-in copper pipe, be difficult to ensure that plasma produces equably on negative pole.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of plasma generator for purifying air simple in structure for above-mentioned prior art, and can guarantee that isoionic exciting in negative terminal surface carry out uniformly.
The technical scheme in the invention for solving the above technical problem is: a kind of plasma generator, comprise lamp socket and the lamp tube body that is arranged on lamp socket seam, it is characterized in that: the inwall of described lamp tube body scribbles conductive layer, the outside spacer sleeve of lamp tube body is provided with metal net mask, described conductive layer and metal net mask respectively with the positive and negative electrode conducting of lamp socket so that form excitation of plasma territory between metal net mask and lamp tube body.
Preferably, the inwall of described metal net mask is evenly distributed with the multiple salient points that can serve as excitation of plasma point, and described multiple salient points lay respectively at the grid intersection place of this metal net mask.After energising, as the metal net mask of negative pole under highfield effect, the setting of salient point, can order about electric charge at more crypto set of the grid intersection place of metal net mask, allow near the electric field intensity of salient point increase severely, cause near its air to be more easily ionized and produce gas discharge, further, be uniformly distributed salient point by the inwall at metal net mask, can guarantee that isoionic exciting in each salient point place of metal net mask carry out equably, thereby make plasma generator perisporium discharge equably positive and negative ion.
The seam of described lamp socket extends outward positive and negative electrode conductive feet, and described anodal conductive feet contacts with conductive layer, and described negative pole conductive feet contacts with metal net mask.
Preferably, described metal net mask close-fitting is in lamp tube body periphery, and described negative pole conductive feet stretches between metal net mask and lamp tube body and with metal net mask and is adjacent to, thereby guarantees that negative pole conductive feet and metal net mask keep good electrically contacting.
Preferably, the front end of described anodal conductive feet is provided with becket, it is inner and contact with the perisporium of conductive layer that described becket stretches into lamp tube body, thereby guarantee as the Electric Field Distribution in anodal lamp tube body evenly, is beneficial to gas electric discharge more equably in excitation of plasma territory.
Described negative pole conductive feet extends axially to the edge of this metal net mask away from lamp socket along outer wall or the inwall of metal net mask, so that even as the Electric Field Distribution on the metal net mask of negative pole.
Compared with prior art, the utility model has the advantage of: smear conductive layer in the lamp tube body inside as anodal, the outside interval of lamp tube body wears the metal net mask as negative pole, realize being uniformly distributed of electric field between positive and negative electrode, make gas discharge be able to carry out equably in excitation of plasma territory, and have simple in structure, be easy to manufacture advantage.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is described in further detail this utility model.
As shown in Figures 1 to 4, the plasma generator in the present embodiment, comprises and is arranged on the lamp socket 1 of built-in transformator 12 lamp tube body 4 of lamp socket seam and is set on the rustless steel guard 3 of aforementioned lamps tube body 4 outsides.The end of lamp socket 1 is provided with for plasma generator being installed to the card base 11 on electrical power connection block, its seam extends outward positive and negative conductive feet 5,6, this lamp tube body 4 is made up of high borosilicate conductor material, and its inwall is evenly coated with graphite layer 41, this rustless steel guard 3 is coaxially arranged on the fixed cover 2 of lamp socket seam with lamp tube body 4, simultaneously, positive and negative conductive feet 5,6 is connected with graphite layer 41 and rustless steel guard 3 respectively through fixed cover 2, and makes to form between the two excitation of plasma territory.
For gas discharge is more easily occurred, on the inwall of rustless steel guard 3, be evenly equipped with multiple salient points 31, each salient point 31 takes shape in the grid intersection place of rustless steel guard.The salient point being distributed on rustless steel guard inwall can induce isoionic exciting in excitation of plasma territory evenly to carry out, thereby makes plasma generator perisporium discharge equably positive and negative ion.
In order to make to be uniformly distributed as anodal lamp tube body with as the electric field on the rustless steel guard of negative pole, in the present embodiment, the front end of anodal conductive feet 6 is also provided with wire netting ring 61, the internal diameter of the external diameter of this wire netting ring 61 and lamp tube body 4 coincide, and can make it to stretch into lamp tube body 4 inside and just contact with the perisporium of graphite layer 41; Negative pole conductive feet 5 stretches between rustless steel guard 3 and lamp tube body 4, and the inwall of being close to rustless steel guard 3 extends axially to the edge of rustless steel guard 3 away from lamp socket 1, carry out more equably between lamp tube body 4 and rustless steel guard 3 thereby realized gas discharge.
The plasma generator of said structure, can realize and between positive and negative electrode, carry out equably gas discharge, and simple in structure, is easy to manufacture.
