Abstract
The utility model relates to a supersonic mosquito banishing device comprising a time-base integrated circuit, a capacitance, a resistor, a switch, a piezoelectric ceramics sheet, a DC electric source, a light emitting diode, a potentiometer and an outer shell. An oscillating pulse signal generated by an oscillating circuit is converted into an ultrasonic signal to cause the resonance of the mosquito wings by emitting the ultrasonic in the space to enable the mosquito to obtain flying dysfunction in order to obtain the purpose of banishing the mosquito. The utility model has the advantages of simple structure, small size, light weight, low cost, low electricity consumption and easy use and is suitable for the living room or the field to banish the mosquito.
Description
The utility model relates to a kind of ultrasonic mosquito expelling equipment.
At present, it is a lot of that people are used for the type of goods of mosquito repellent, kill mosquito, as medicine, mosquito-repellent incense, electric mosquito mat and electronic mosquito repellent etc.Use medicine, mosquito-repellent incense and electric mosquito mat mosquito repellent, kill mosquito, mosquito is developed immunity to drugs, and be subjected to the restriction of use occasion, can't obtain desirable repelling effect.And in existing electronic mosquito repellent, have because complex structure, cost is higher, is difficult for promoting the use of; What have is then true to nature inadequately owing to analog pulse, and repelling effect is unsatisfactory.
The purpose of this utility model is to overcome weak point of the prior art and a kind of simple in structure, cheap, repelling effect ultrasonic mosquito expelling equipment preferably is provided.
Technical solution of the present utility model is: a kind of ultrasonic mosquito expelling equipment, its circuit is by time-base integrated circuit IC, resistor R
1, R
2, R
3, capacitor C
1, electrolytic capacitor C
2, C
3, switch S, potentiometer R
P, piezoelectric ceramic piece B, light emitting diode VD and dc source GB form, wherein 1 pin of IC and GB negative pole, C
3Negative pole and VD positive pole join and ground connection, C
1Be connected between 1 pin and 2 pin of IC, switch S is connected between 4 pin of GB positive pole and IC, and 4 pin of IC link to each other R with 8 pin
1Be connected between 7 pin and 8 pin of IC R
2Be connected between 6 pin and 7 pin of IC C
3Anodal, R
PThe end of one end and B is connected R with 7 pin of IC
PThe other end and C
2Positive pole joins, the other end of B and R
3And R
PSliding contact be connected R
3The other end and VD negative pole join.
Be provided with an external power supply jack (4) between two utmost points of dc source GB of the present utility model.
Compared with prior art, the utlity model has simple in structurely, volume is little, and is in light weight, and cost is low, little power consumption, and advantage easy to use, and, human body is not had harm to the environment no electromagnetic pollution.
Following accompanying drawing has been described an embodiment of the present utility model.
Fig. 1 is the circuit theory diagrams of the utility model embodiment.
Fig. 2 is the outline drawing of the utility model embodiment.Wherein: 1 expression plastic casing; The potentiometer dial of 2 expression belt switches; 3 expression indicator lamps (light emitting diode VD); 4 expression external power supply jacks; 5 expression fixed screws.
The utility model will be further described with reference to the accompanying drawings and in conjunction with the embodiments.
With reference to Fig. 1, Fig. 2,555 time-base integrated circuit IC and the peripheral resistance R that is connected
1, R
2, capacitor C
1Deng oscillating circuit of composition, this oscillator produces a frequency of oscillation at once when closing a switch S, and parameters such as the height of this frequency of oscillation and cycle are by resistance R
1, R
2, capacitor C
1Decision, frequency of oscillation is transported on the piezoelectric ceramic piece B after straight, coupling through electrolytic capacitor, converts ultrasonic to spatial emission by piezoelectric ceramic piece B.This ultrasonic can cause the resonance of mosquito wing aloft, makes the dysfunction of circling in the air of mosquito, thereby reaches the effect of mosquito repellent.
The utility model is powered with 9 volts of laminated cells, and also available external power supply power supply power supply is by potentiometer R
PCan regulate the size of emission ultrasonic power, and indicate the on/off situation with light emitting diode VD.The maximum mosquito repellent scope of this mosquito expelling equipment can reach 40 square metres, can be used for indoor or open-air mosquito repellent.
