In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with example, the utility model is further elaborated.
The utility model comprises a shell, built-in electronic circuit and built-in lithium battery, described electronic circuit comprises intelligent processor, management of charging and discharging module, pulse power amplifier circuit, LED pulse-width modulation lighting module, pulse power amplifier circuit, LED battery capacity indication circuit, power circuit and pulse mosquito repellent circuit, intelligent processor respectively with pulse power amplifier circuit, button circuit, management of charging and discharging module, LED battery capacity indication circuit, the electrical connection of LED pulse-width modulation lighting module, pulse power amplifier circuit is electrically connected with power circuit, management of charging and discharging module is connected with lithium battery, described management of charging and discharging module comprises charging circuit and discharge circuit, described charging circuit connects BUCK circuit by intelligent processor, the 5V voltage of Micro USB is charged to built-in lithium battery by reduction voltage circuit, discharge circuit connects BOOST circuit by intelligent processor, by booster circuit, the boost in voltage of lithium battery is exported to 5V, pulse mosquito repellent circuit amplifies by power discharge main road the pwm pulse ripple of the 21KHz ~ 23KHz of intelligent processor output gap to pwm pulse ripple, export through piezoelectric ceramic buzzing sheet.Described LED pulse-width modulation lighting module comprises a high-brightness LED lamp, realizes LED brilliance control by pulse-width regulated.Described LED battery capacity indication circuit is by 4 real-time electric weight of small LED lamp instruction internal cell, and electric weight detects by intelligent microprocessor and obtains information about power by detecting lithium battery voltage and charging and discharging currents.
The utility model is made up of shell, built-in electronic circuit and built-in lithium battery.Outer casing frontispiece embeds LED instruction and illuminating lamp, button 1 and button 2, for lighting switch control function and electronic mosquito expelling control function.For charging, MICRO USB interface, electric discharge USB interface are welded in electronic circuit board and are embedded in shell side in order to realize its function.
Circuit board of the present utility model relies on built-in lithium battery power supply, in the time of lithium battery quantity not sufficient, by MICRO USB mouth, built-in lithium battery is charged, and by USB mouth, the power consumption equipment such as mobile phone, panel computer is charged.Electronic circuit board is controlled its also discharging function that charges.
Circuit board integrated electronic pulse mosquito repellent circuit of the present utility model, exports characteristic frequency electronic impulse ripple by single-chip microcomputer, and electronic impulse ripple is used for expelling the mosquito of certain distance by power amplification circuit.Lithium electricity power supply in this circuit relies on.
Below main circuit feature of the present utility model is set forth.
As shown in Figure 2, charging circuit carries out step-down by BUCK circuit of intelligent processor control by the 5V voltage of obtaining from Micro USB built-in lithium battery is charged, whole charging process is divided into four parts, i.e. precharge, constant current charge, constant voltage charge and trickle charge.
In the time that charging circuit is started working, whether intelligent processor can detect cell voltage lower, if, adopt a smaller constant current to charge to battery, when cell voltage rises after the safe voltage value of setting, charging current keeps higher value constant, normally 10 of pre-charge current times or larger.Under precharge and constant current charge state, the voltage that intelligent processor can continuous monitoring battery, when the voltage in single-lithium-battery pond reaches 4.2V, constant current charge state finishes, and proceeds to constant voltage charge state.Under this state, charging voltage is constant in 4.2V.When the electric current of lithium core drops to after original 1/10, constant voltage charge state finishes.At trickle charge state, after battery full charge, if portable power source is still inserted on charger, battery can lose electric weight due to self discharge.Intelligent processor can be with very little electric current to the charging of lithium core, the loss bringing to supplement self discharge.
As shown in Figure 3, discharge circuit is exported the boost in voltage of lithium battery by a BOOST booster circuit of intelligent processor control to 5V, restriction output simultaneously maximum current.In the time that intelligent processor detects that the current continuity of output is 0 in 5 seconds, can automatically carry out low-power consumption mode, adopt the mode of interval output, once detect that load is inserted on the USB1 or USB2 of output, can automatically enter normal mode of operation, output 5V voltage uses to load.
As shown in Figure 4, the mosquito that stings people is all generally the female mosquito of bosom ovum, and male mosquito does not sting people.And female mosquito is not liked during ovum in bosom approaching with male mosquito, they one feel that frequency that male mosquito sends is 21---the ultrasonic signal of 23kHz, and will keep away and leave away.The utility model is controlled the pwm pulse ripple of the 21KHz ~ 23KHz of intelligent processor output gap by button 1, and by power discharge main road, pwm pulse ripple is amplified, make its ultrasonic wave that sends the male mosquito of simulation through the output of piezoelectric ceramic buzzing sheet, thereby expel female mosquito, avoid mosquito bite.
