Description

Imitative sound, band electronic mosquito expelling equipment

The utility model relates to the stationary installation of seizure or kill insects, is meant that especially a kind of YT-08 of employing type speech IC is mini imitative sound, the band electronic mosquito expelling equipment of main element.

Existing mosquito repellent method commonly used has mosquito-repellent incense, chemical culicifuge, high pressure Mosquito killer lamp and electronic mosquito repellent etc. multiple.The principle that adopts electronic mosquito repellent mosquito repellent method mainly is to utilize the cerebral nerve that can produce 20-23KHz even higher high-frequency electric wave damage mosquito, makes it dizzy and dare not be near the mosquito repellent control area.Though these electronic mosquito repellents that use have certain repelling effect at present, but the high-frequency electric wave that is produced when carrying out mosquito repellent also often produces injury greatly to human brain, long-term use can make the people produce giddy, dim eyesight, nauseating sensation, influence the health of human body and brain, thereby the expansion that has limited electronic mosquito repellent is promoted the use of.

The purpose of this utility model just is to overcome the defective of existing electronic mosquito repellent, it is main element that a kind of employing YT-08 type speech IC is provided, and add peripheral oscillating circuit, make it produce mini imitative sound, band electronic mosquito expelling equipment that sound that imitative male mosquito wing shakes and hunting of frequency are the 2.5KHz sound wave.

The utility model adopts mini clamping type contour structures, is made of housing, clip, switch, screw and wiring board, and housing is installed clip outward and switch is set, and wiring board is installed in the housing, by screw the housing upper and lower cover is connected as a single entity; Wiring board partly comprises power supply, electric capacity, resistance, triode, speech IC, buzzing sheet and switch etc., and the model of speech IC is the YT-08 type, and it is connected with electric capacity, buzzing sheet, resistance, triode and switch and power supply respectively.When toggle switch is closed, power supply power supply, the speech IC output signal pipes through the buzzing sheet, sends the imitative male mosquito wing sound that shakes, peripheral oscillating circuit sends the vibration sound wave that frequency is 2.5KHz by buzzer simultaneously, with the attack of double effects repel mosquitoes to human body.The specifications parameter of the main element of circuit board section is as follows:

1, buzzing sheet diameter 15mm is 1; 2, electric capacity 0.1 μ F is 1;

3, power supply AG13 battery 1.5V is 1; 4, the switch toggle switch is 1;

5, resistance R ₁, R ₃Be 2 of 1.8K Ω; R ₂, R ₄Be 2 of 2.7K Ω;

6, triode OUT ₁, OUT ₂Model 9013;

7, speech IC model YT-08.Housing appearance and size of the present utility model is generally long * wide * thick be about 60mm * 18mm * 12mm, can also be according to the size of concrete environment for use and needs change housing profile.The technical program determine that being based on following mosquito repellent principle designs: general male mosquito is not sucked blood, and female mosquito need suck the mankind or animal blood at post-coitum and replenishes nutrient and lay eggs to treat the development of ovary, and female mosquito utmost point is afraid of that male mosquito is near harassing and wrecking during this.Utilize this habit of mosquito, the wing frequency that the sound that produced and bat send of shaking is the sound wave of 2.5KHz when sending imitative male mosquito flight with electronic mosquito repellent, female mosquito will take for male mosquito and bat near and run away rapidly, thereby reach the purpose of driveing the female mosquito of sucking blood.Through to the analyses of 123 kinds of mosquitoes of China, the mosquito kind of at first inhaling human blood mainly is anopheles minius and Culex pipiens pallens, in south China, the survival rates of East China, southwest and other these two kinds of mosquitoes of most of area accounts for about 80% of the mosquito kind of sucking blood.Design of the present utility model is exactly to utilize life and the blood-sucking habit of mosquito, designs as the main object of mosquito repellent with these two kinds of mosquitoes simultaneously.Mosquito repellent of the present utility model is 4 meters apart from diameter, and reach more than 200 hours the service life of every piece of battery.

Advantage of the present utility model just is owing to adopt the YT-08 speech IC, and it is the sound wave of 2.5KHz that electronic mosquito repellent only sends shake sound and frequency of imitative male mosquito wing, thereby human body and brain are not constituted injury; Adopt mini clamping type contour structures simultaneously, carry, place and use all very convenient.Imitative sound of the present utility model, band electronic mosquito expelling equipment are nontoxic, harmless, noiseless, can be suitable for the use of any occasion, thereby have the vast market promotion prospect.
