Description

Electronic screen window for killing fly and mosquito

The utility model is a kind of electric household appliance of killing the indoor and outdoor mosquitos and flies with the electronic method large tracts of land.

Domestic and international existing electronic mosquito and fly killing device as electronic mosquito-killing lamp, electronics fly killer, electronics fly eradication cage etc., all is to adopt the trapping mode, allows mosquitos and flies contact high-voltage fence, and reaches the purpose of killing mosquitos and flies.Two kinds of electronics fly eradication circuits are disclosed in the domestic electronic circuit collection of choice specimens (week secondary volume, Shanghai scientific and technical literature publishing house, 1984 the 62nd page) book.It is confined to smell and lures mode, and the fly that attracts is more than what tag, and contaminated environment, and circuit design is unreasonable in addition, and is very dangerous, can't apply.The sort of is the Mosquito killer lamp of luring light source with black light lamp (ultraviolet lamp), and the result of use extreme difference is because phototaxis is not the key property of mosquito.The electronics that " electronics newspaper " in 1982 initiates lures in the kill mosquito technical discussion, to only adding high pressure to the electronic mosquito-killing lamp that hits the murderous intention reason with photo-induction negates basically.

The purpose of this utility model provides a kind of shortcoming that overcomes the above-mentioned device that wipes out the flies and mosquitoes, energy large tracts of land, long-time, pollution-free (comprising smell, Electromagnetic Interference), high efficiency, the safe and reliable device of killing mosquitos and flies.

Realize the purpose of this utility model by following design: make full use of phototaxis, the smell of mosquitos and flies, this rule of susceptibility of temperature, make a kind of high pressure generator and be respectively the bipolar electrode window screening identical with general window gauze hole that metal wire interweaves with nylon wire through, parallel and link to each other, existing mechanical protection has the tag electronic mosquito and fly killing screen window of function of electronics again.High pressure generator is made up of rectification, filtering, vibration, high pressure conversion, energy storage, current-limiting protection circuit.Adjacent two wires of mosquitos and flies striking screen window reach and hit the purpose that wipes out the flies and mosquitoes.

The utility model has been held the main thoroughfare-window of mosquitos and flies harm humans, make full use of the various characteristics of mosquitos and flies, as the regularity of sooner or later coming in and going out, phototaxis, to the susceptibility of smell, temperature, block the way to cut and kill, successively kill the indoor and outdoor mosquitos and flies, realized large tracts of land, long-time, pollution-free, kill flies and mosquitoes expeditiously.Owing to adopt the bipolar electrode window screening identical with general window gauze hole, mechanical protection and electronics are tagged to be combined, under the situation of switching on, play a part actively to kill, cut off the power supply or situation such as screen window short circuit under, still can play the protective action of common screen window.High pressure generator part with reference to international IEC standard and similar Electrical Appliances Designing circuit parameter, and, guaranteed safe in utilization with a plurality of resistance composition current-limiting resistances.On circuit structure, the regulation with reference to " safety of family expenses and similar electrical equipment " in the IEC standard has adopted reinforced insulation and double insulation, has reached the standard of II level electrical equipment.Because the high-voltage fence series products of simple protection, still not having standard in the product for civilian use can comply with, therefore adopted analogy method in design, make this electrical equipment touch all be better than aspect human body and the safe electric weight similar devices of finalizing the design and electrical equipment (analogy following electrical equipment: the XCT-B of integrated electronics factory of Xiamen University type defibrillation is transferred rich device; The semiconductor electronic pulsating stimulators of Beijing Medical Instruments factory; Products such as the JXD-2 type audio frequency therapeutic apparatus for treating of Broadcasting Appliances Factory, Jiaxing).Also with reference to following document: " household electrical appliances safe practice " petro chemical industry publishing house; " external earth leakage protector " scientific and technical literature publishing house; " safety of medical electronic apparatus " (Japan) People's Health Publisher; " safe practice handbook power industry publishing house; " static handbook (Japan) Science Press; " external household electrical appliance standard compilation " volume Shanghai City, (2) (3) (4) hand pipe office scientific and technological information chamber.Thereby the capacity, output voltage, current-limiting protection resistance parameter (output voltage direct current 1200V, human body striking discharge time about 0.6 millisecond) of the energy-storage capacitor of high pressure generator have been determined.When the human body accident contacts window screening, can only be through the skin striking, and strong picotement is arranged, but therefore discharge capacity there be very big safe clearance much smaller than above-mentioned similar electrical equipment.

Below come further the utility model to be given concrete narration by drawings and Examples:

Fig. 1 is the utility model structural representation; Fig. 2 is the utility model high pressure generator electrical schematic diagram.

Embodiment:

Accompanying drawing 1 mesohigh generator (1) becomes high direct voltage with the civil power alternating current 220V, receive by lead (2) on two electrodes (4) of bipolar electrode window screening (3), two electrodes (4) in order respectively with the wire (5) of double joint window screening (3) in 1,3,5 ... with 2,4,6 ... join, guarantee that the polarity of adjacent two one metal wires is opposite.The mesh of double joint window screening guarantees identical with the mesh of common plastics silk and wire window screening, and just warp and parallel are respectively metallic conductor and insulator.The principle of high pressure generator is seen accompanying drawing 2, wherein capacitor C ₀Be storage capacitor, directly in parallel with output, resistance R _XLBe current limliting protective resistance (R wherein _XLFor several resistance are formed).Power transformer B ₁The alternating current 220V civil power is become low-voltage AC become direct current, again through capacitor C through silicon bridge GQ ₁Supply transistor T and vibration output transformer B after the filtering ₂Use; B ₂The high pressure winding with high-tension current through R _XLTo C ₀Charging makes the high pressure generator output be in the high pressure wait state all the time.R under the situation of high-voltage output end short circuit _XLPlay the current-limiting protection effect.Wherein ND is C ₀Discharge and short circuit indication.

Preferred embodiment of the utility model is to buckle and so on knit goods as protection network as the net that the electronic mosquito and fly killing screen window in the family should be equipped with big mesh, is hung on the Lower Half of window, does not make old man, patient, children touch window screening and get a fright.Also can on high pressure generator, install additional,,, further improve security performance automatically with high voltage short circuit when human body during near screen window near switch.The utility model can be widely used in family, restaurant, food processing factory, marine product and Leather Goods Factory, support many mosquitos and flies places such as fowl, stock keeping specialist.

Claims (1)

1, the electronic mosquito and fly killing screen window is made up of high pressure generator and the bipolar electrode device of tagging, and it is characterized in that said high pressure generator [1] also comprises by capacitor C ₀Accumulator and the multistage resistance R formed _XLThe current-limiting protection circuit of forming, the device of tagging adopts the bipolar electrode window screening [3] identical with general window gauze hole.
