During enforcement, this power supply module is a dry cell power supply module, comprising:
One battery chamber has one and supplies the accommodation space of dry cell setting; And
One direct current connects this battery chamber to DC converting circuit, and receives and change direct current voltage to one driving voltage of this dry cell.
During enforcement, this power supply module is a commercial power supply module, comprising:
One attaching plug, in order to receive a line voltage: and
One exchanges DC converting circuit, and receiving this line voltage and changing this line voltage is a driving voltage.
During enforcement, this frequency generating circuit is a frequency size of setting this oscillator signal with the linear frequency sweep mode over a range of frequencies back and forth.
During enforcement, this frequency generating circuit comprises:
One counter changes time point in order to decision one-period medium frequency; And
One trimmable resistance has a resistance value, this resistance value size of the time point adjustment that this trimmable resistance sets according to this counter, and to set out the oscillator signal of different frequency, wherein, the frequency of this oscillator signal is to should resistance value.
During enforcement, this frequency generating circuit is that one type of linear saw-tooth wave produces circuit.
During enforcement, the described multifrequency output of the utility model insect expelling device more includes a random number producer, and this unrest number producer connects this frequency generating circuit, exports a setting value with random number, for the frequency of this insect expelling device according to this this oscillator signal of setting value adjustment.
During enforcement, this signal output apparatus is a buzzer.
Therefore; According to the above-mentioned structure that discloses; The multifrequency of the utility model output insect expelling device improved traditional because of fixing expelling parasite frequency signal to the shortcoming of mosquito generation auditory fatigue; And have the oscillator signal of different frequency through output, avoid the situation of auditory fatigue to take place, and then strengthened the effect of expelling parasite.
