Description

High voltage static indoor air purifier

The utility model relates to a kind of air purifier, especially can carry out the device of purified treatment to the air of bedroom, parlor, meeting room.

Along with the raising of people's living standard, people begin to note the living environment of oneself, require room, smoking place that good fresh air is arranged.For this reason people often adopt filtering type, electronic type or electronics filter composite device to air filter, dedusting.At present, the KQ-II type air cleaner of selling on the market (producing) by Chinese-foreign joint Shanghai Heng Feng Electrical Appliances Co., Ltd, its structure is made up of blower fan, high pressure generator, prefiltering net, corona polarizing device, dust-collecting box, filter cartridge, spice box.Deficiency is that its corona polarizing device adopts negative ion generating device, and the dedusting electric field is open, not only bad for the concentration of energy of dedusting field, but also causes the utilization rate of dedusting field to descend, and influences the purification efficiency of whole device to air; Its high pressure generator power output is less, when the high slightly smog of concentration enters the dedusting field through the negative pressure of blower fan, also has most smog to discharge from exhaust outlet, therefore at this moment the purification efficiency of smog is seemed lower; Its filtration treatment parts are fixed with medium, and be not easy to the user and change and set the spices oneself like or be rich in adsorbing material, or drier etc.The disclosed notification number of Chinese patent is CN 2077752U, and its name is called the static smoke and dust purifier, is made up of clarifying smoke case, corona polarizing device, high pressure generator (technical scheme how high pressure produces is not open) and blower fan.Deficiency is clarifying smoke case interior corona polarizing device and control of dust (processing) device, spatially is arranged in order, complex structure, volume is big, the manufacturing cost height, more converge district's work, be unfavorable for family or indoor promoting the use of because of whole device performance is particularly suitable for electric welding.

The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of power ratio bigger, and the dedusting field energy is concentrated, and is simple in structure, makes things convenient for the user, be suitable for family or indoor promote the use of air purifier.

To achieve these goals, power control, high pressure generator, blower fan, control of dust processor, laying dust device, filtration sylphon can be set in casing.Wherein blower fan, control of dust processor, filtration sylphon are arranged in order; Power control and high pressure generator are positioned at a side of control of dust processor.

Establish switch, fuse, transformer in the power control.Transformer input wiring terminal and plug join, and are convenient to external AC mains source, and its output joins with the input of high pressure generator.Establish the whole pi type filter circuit of bridge-type in the high pressure generator, the Transformer Winding centre cap between the two transistor colelctor electrode joins the output of this circuit in the transformer feedback pair transistor push-pull oscillator circuit with being connected on.Feedback circuit is made of the auxiliary winding with inverting function, feeds back to two transistorized base stages with the character of recommending respectively.The load winding connects the load voltage doubling rectifing circuit, and the positive pole of its output joins with laying dust tube, metal ring in the control of dust processor respectively, and negative pole joins with the corona wire in the control of dust processor.

The control of dust processor is by the laying dust tube, and high voltage insulation air inflow board, high voltage insulation exhaust board, corona wire, metal ring, whirlwind directive wheel are formed.High voltage insulation air inflow board, high voltage insulation exhaust board are all beaten a lot of equally distributed apertures that are used to let in air thereon by High-Voltage Insulation sheet material material and are made, and its profile is interior identical along shape with the laying dust tube cross section that is adopted.Two plates are fixed by three equal length and the stainless steel wire that equals laying dust tube length degree.Three stainless steel wires are symmetric arrays abreast, perpendicular to two plates; Two ends embed the edge of two blocks of High-Voltage Insulation plates that are positioned at its two respectively, make three embedded holes on every plate about the geometric center symmetry of plate.Corona wire (copper cash) is along between the geometric center that axially is erected at two boards, and fixes with securing member.The sheet metal annulus is parallel to the high voltage insulation air inflow board near it.With three thin bars of high voltage insulating materials it is fixed on three stainless steel wires, and corona wire is positioned at perpendicular to anchor ring on its symmetrical centre axis.The whirlwind directive wheel makes with the high voltage insulating materials of lightweight, and it is fixed on the corona wire, is positioned at the back of metal ring.Its five fritter blades are all swung to high voltage insulation exhaust board one side, become 35 degree angles with corona wire, to allow the negative oxygen ion that produces between metal ring and corona wire can change the inertia motion direction, motion thereafter can be scattered everywhere in the laying dust tube, prevent from directly to be rebounded; One side of each blade exterior all outwards turns down 10 degree angles, and the negative oxygen ion that allows can arrive at the back of blade from the slit between two blades under the effect of inertia motion, in case dedusting field " dead band " occurs, influence the utilization ratio of dedusting field energy.High voltage insulation air inflow board, high voltage insulation exhaust board, corona wire, metal ring, whirlwind directive wheel constitute deduster jointly.Deduster and laying dust tube constitute the control of dust processor.Whole deduster edge is enclosed within the laying dust tube, can freedom therefrom extract out, or the edge cover is entered.

The laying dust device is rolled by flake aluminum (band) overcoat one deck plastics and forms, some little plastics that protrude " point " on the plastics of aluminium flake outside, in case when rolling layer with layer between do not have the slit and influence passing through of air-flow.Rolled aluminium strip is inserted in the box, laterally snaps in the interior a pair of groove of casing, and between control of dust processor and filtration sylphon, and over against high voltage insulation exhaust board.

Filtration sylphon in the casing be with mutually over against the cuboid box made of two wire nettings, three side-closed of box are convenient to the user and are packed into or pour out adsorbent or spices from the opposite side opening part.Whole filtration sylphon laterally snaps in a pair of groove of casing, and makes its opening up, is parallel to the laying dust device, is right against the gas outlet of casing.Filter sylphon central authorities and also have an aperture,, damage blower fan in case the material that the user drops into stops up.Casing is provided with air inlet and gas outlet.Between air inlet and blower fan, be provided with the layer of metal net, enter in the casing in order to prevent extraneous various macro object.

High pressure generator of the present utility model has adopted transformer feedback bicrystal push-pull oscillator circuit, has than higher and stable power to offer the control of dust processor.Because the dedusting field of control of dust processor is limited in becoming containing field in the laying dust tube, has concentrated the energy of dedusting field, can concentrate purified treatment to the air of blower fan inspiration.The equally distributed aperture of high voltage insulation air inflow board evenly distributes the air of blower fan inspiration to the dedusting field, has so just fully effectively utilized the energy of dedusting field, has improved efficient.Owing to also be provided with the filtration sylphon, also just made things convenient for the user to select oneself spices and adsorbent again.

Below in conjunction with accompanying drawing the utility model is further described.
