Embodiment

Below in conjunction with description of drawings embodiment of the present utility model is described in further detail.

Anticipate as shown in the figure, this kind electronic mosquito repellent, it includes housing, the circuit board that control circuit is arranged in the housing, it adopts and is convenient for carrying structure, as Fig. 1-7 signal, its housing 1 is fixed on the watchband 2, and housing 1 rear surface has eye-splice pin 11, on the watchband button hole 21 is arranged simultaneously, housing with regard to eye-splice on watchband, electronic mosquito repellent can tie up on people's the wrist like this, also can be directly by 11 eye-splices of eye-splice pin on people's belt, use very convenient, power supply adopts button cell 3, the battery cavity of set battery is arranged in housing, be equipped with battery cover 12 above, the battery cavity opening on battery cover and the housing adopts snapping to be connected, to be convenient for people to change battery, in transducer sounding position, have tiny open-work on the housing, can design electronic timer on the housing simultaneously, the signal input part of its liquid crystal display circuit connects the time signal output of single-chip microcomputer, is convenient for people to open-air the use.It has the control circuit that is used for producing various bionical sound waves, illustrate as Fig. 9 circuit block diagram, control circuit has power unit, oscillator signal to produce circuit, amplifying circuit and transducer, power unit output connects the power end that oscillator signal produces circuit and amplifying circuit respectively, oscillator signal produces circuit signal output termination amplifying circuit signal input part simultaneously, the amplifying circuit signal output part removes to connect transducer, wherein oscillator signal produces the circuit that circuit is the employing single-chip microcomputer, and the program that is used for producing multiple bionical thing principle electronic signal is housed in the single-chip microcomputer.Power unit adopts little, the lightweight button cell of volume here, and its output becomes power end and connects the power end that oscillator signal produces circuit and amplifying circuit successively in succession, for they provide operating voltage.Single-chip microcomputer IC ₁Power end connects the power unit output and ground respectively, and reset terminal passes through capacitor C
