Abstract

The utility model discloses a mosquito trapping fan. A mosquito luring lamp is provided between a front cover and a blade, the supporting rack of the motor is provided with a super-audio generator for luring mosquitos, the wind discharging end of the casing of the fan is a mosquito sealing cavity whose air discharging end closing to the blade is a hinged window, an airflow outlet end is a screen net cover, the inner periphery of the radical direction of the cavity is a high-voltage frame, and the inner cavity of the casing is black. The mosquito trapping fan uses a lamp light, a supersonic and the black inside the cavity to lure the mosquitos and suck the mosquitos into the mosquito sealing cavity, having wind cooling and mosquito trapping functions. The mosquito trapping fan can also singly be used for trapping the mosquitos and can make the room of 20 square meters have no the mosquitos in about 30 minutes through experiments.

Description

Mosquito trapping fan

The utility model relates to a kind of electric fan of family expenses, particularly can trap the electric fan of mosquito.

Kill mosquito or the easy befouling environment of mosquito repellent with medicine.Moreover use the mosquito in summer of fan just rampant at need, when medicine mosquito repellents such as use mosquito-repellent incense or electric heating mosquito sheet, if the fan blowing of blowing in is enjoyed the cool, air stream makes it to lose due effectiveness by freely then having reduced airborne drug concentration.Existing the initiative of its kill mosquito is poor with the ultraviolet attracting mosquitoes and with the mosquito killing device of high-voltage electric shock, and it is just effective to need mosquito knock electrical network, and high-voltage fence needs to power continuously, and its power consumption is compared with catching the mosquito effect, seems less economical.

The utility model purpose be provide both can dry nice and cool, but attracting mosquitoes is is initiatively catched and killed again, and medicine-less pollution catch the mosquito fan.

Conventional electric fan and conventional fan control circuitry, superaudio generation circuit, timing reverse circuit and high-pressure generating circuit that the utility model has housing, front shroud, motor, flabellum to constitute.Between front shroud and flabellum, mosquito luring lamp is housed, the ultra-tone generator that dress lures mosquito on electric machine support.Air outlet at blower-casting has a mosquito trap cavity.This chamber be hinge window by the flabellum end, airflow outlet end only have can mosquito can not be bored by air-flow the gauze cover.Cavity between hinge window and the gauze cover radially inner periphery is the high-tension electricity frame.

Hinge window is by a plurality of sheet loose-leaf vertical arrangements, and each movable sheet upper end is hinged with the axle bar, and axle bar two ends are separately fixed on the inwall of housing both sides.In nature, lean on last movable sheet according to gravity sag relatively, take a slice loose-leaf that is right after under it, promptly hinge window is in closed condition.Air-flow blew movable sheet and makes it to be tending towards level when flabellum rotated, and hinge window is opened.

On the inwall of high-tension electricity frame, many strip electrodes arranged side by side, the polarity difference of adjacent electrode.

The housing inner chamber of electric fan is black.

The described mosquito fan of catching has adopted the black in light, ultrasound and the chamber to lure near the suction port of fan flying mosquito, and the inlet stream of fan can will fly the mosquito suction and enter mosquito trap cavity by the hinge window of opening.Fan stops hinge window and cuts out automatically, mosquito is confined in the mosquito trap cavity, the high-tension electricity frame is switched in short-term and can be shot mosquito in the chamber dead, and the consumed power of needn't switching on for a long time, the utility model collection is cool, mosquito catching function is an one, also catches mosquito in the time of blowing, in the time of need not catching mosquito, cut off the power supply of mosquito luring lamp and superaudio device, can make conventional fan and use.Do not need coolly only to catch mosquito with it, can adopt and regularly catch the mosquito shelves, that is: work started flabellum automatically in short-term mosquito is sucked mosquito trap cavity when mosquito luring lamp and superaudio device were long.Described fan is through experiment: 20 square metres room can all fly mosquito and catches in about 30 minutes with indoor.In addition few mosquito area establishes respectively that a window often opens in many mosquitos area, rural area and city catches the mosquito laboratory, puts described fan in regularly catching mosquito shelves continuous operation one month indoor, catches in many mosquitos area surplus the mosquito 30,000, and over thousands of of mosquito is caught in few mosquito area.

Fig. 2 is the sectional view of Fig. 1.

Fig. 3 is the rear view of Fig. 1.

Housing 1, front shroud 2, motor 4, flabellum 3, fan control circuitry have constituted box fan.Superaudio generation circuit has adopted " the wide band diluted colour multi-vibrator " in " intergrated circuit is used 500 examples " of 83 years versions of post and telecommunications publishing house, regularly reverse circuit has adopted " electronics newspaper " 89 year 43 phase " ventilation fan automatic timing control wiring ", high-pressure generating circuit is that voltage doubling rectifying circuit is prior art, and entire circuit is contained in the sidewall chamber of housing 1.Superaudio generation circuit connects ultra-tone generator and produces 2-2.5 megahertz superaudio, and regularly reverse circuit is used for regularly catching the mosquito shelves, and it makes ultra-tone generator 7 and mosquito luring lamp 6 normal opens, and per hour once upset is in short-term connected flabellum motor 4.High-pressure generating circuit output termination high-tension electricity frame 12.Wavelength is that the ultraviolet mosquito luring lamp 6 of 2537 dusts is contained between front shroud 2 and the flabellum 3.Ultra-tone generator 7 is contained on the electric machine support 5.Air draft side at flabellum 3 has a mosquito trap cavity 9.This chamber leans on flabellum 3 ends that the loose-leaf 11 of a plurality of vertical arrangements is arranged, and each loose-leaf is hinged with axle bar 10, and axle bar 10 two ends are fixed on the housing 1, constitute hinge window 8.The outermost end in chamber 9 has easily detachable guard frame 14, and its central hole has gauze cover 13.Cavity inner periphery between hinge window 8 and the gauze cover 13 is a high-tension electricity frame 12, and it is an insulating material, plating inner surface many conductive layers arranged side by side, i.e. electrodes.Adjacent conductive layer polarity difference, housing 1 inner chamber of electric fan is black.
