Abstract
The invention discloses an electronic mosquito-repelling device. The electronic mosquito-repelling device is powered up by a direct current power supply, and comprises an MCU (Microprogrammed Control Unit), a digital-to-analog converter, a power amplifier, at least one ultrasonic transducer and sound wave reflectors with equal quantity, wherein the MCU, the digital-to-analog converter, the power amplifier and the ultrasonic transducers are sequentially connected; the ultrasonic transducers are just opposite to the sound wave reflectors; when running a main program in the MCU, a subprogram with digital bat pulse ultrasonic wave beams is randomly invoked; the digital signals are sent to the digital-to-analog converter to be converted to analog signals and be enhanced; the power amplifier is amplified to drive the ultrasonic transducers; then the ultrasonic transducers emit the recovered bit pulse ultrasonic wave beams to the sound wave reflectors, so that the sound wave can be spread all around. The bat is a natural energy of injurious insect such as mosquito and fly, and when the pulse ultrasonic wave beams of the bat hit the injurious insect, the insect can quickly escape from the site by the instinct of avoiding harm, so that invading and harassing of the injurious insect such as mosquito and fly to human and livestock can be effectively avoided. As the ultrasonic frequency of the bat is beyond the audible area of human ears, and the device is free from interfering people, causes no harm to health, and is safe and environment-friendly.
Description
Affiliated technical field
The present invention relates to a kind ofly can produce ultrasound beamformer and drive the electronic mosquito expelling fly device of mosquitos and flies, especially can produce the electronic mosquito expelling fly device of high emulation bat pulse ultrasonic wave wave beam.
Background technology
As everyone knows, mosquito, fly can be propagated various diseases in the mankind and domestic animal, very harmful.Therefore, people usually hide the harm of mosquitos and flies with mosquito net, screen window, mosquito-repellent incense.Also work out a lot of technology and eliminated or driven mosquitos and flies, as agricultural chemicals, Mosquito killer lamp, electronic mosquito repellent etc., done a lot of effort and exploration.Mosquito-repellent incense, agricultural chemicals also contaminated environment in repellent mosquitos and flies, harm people's is healthy, although Mosquito killer lamp, mosquito expelling equipment etc. have certain effect, because of catching the key of mosquitos and flies, effect is not cited.
Summary of the invention
We know, ultrasonic is the pencil sound wave of straightline propagation; Bat is the natural enemy of mosquitos and flies, and it relies on the echo of the pulse ultrasonic wave wave beam of detection self transmitting to survey the orientation of prey, preys on.All animals have the instinct of hiding harmful animal, and when the pulse ultrasonic wave wave beam of bat hits mosquitos and flies, they will be made an escape.The invention provides a kind of electronic mosquito expelling fly device, it uses modern electronic technology, can produce high emulation bat pulse ultrasonic wave wave beam, and to all the winds propagates.Can effectively drive mosquitos and flies.
The technical solution adopted for the present invention to solve the technical problems is: with low-voltage dc power supply be whole circuit supply, in MCU, store a main program, and several digitized, can supply subprogram main program random call, that contain the pulse ultrasonic wave wave beam information that does not belong to same bat.Change into the analog signal of amplification, further amplify and promote ultrasonic transducer through power amplifier by digital to analog converter when main program recalls subprogram, high emulation ground restores the pulse ultrasonic wave wave beam of bat, directive acoustic wave reflector, acoustic wave reflector is to all the winds propagated pulse ultrasonic wave wave beam.
The invention has the beneficial effects as follows, because pulse ultrasonic wave beam signal is different in subprogram, under the random call of main program, an electronic mosquito expelling fly device just can simulate the scene of the extensive predation of a group bat.After mosquitos and flies and other pterygogenea insect are hit by bat pulse ultrasonic wave wave beam, keeping away under harmful instinct orders about, promptly flee the scene; Thereby effectively avoid the invasion of the insects such as mosquitos and flies to the mankind and domestic animal.The frequency of the pulse ultrasonic wave wave beam of bat exceeds listening outside territory of the mankind, can not affect people's normal life and rest, harmless with health, the requirement of salubrity environmental protection.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing is a theory diagram, 1. dc source in figure, 2. MCU, 3. digital to analog converter, 4. power amplifier, 5. ultrasonic transducer, 6. acoustic wave reflector.
Embodiment
In the drawings, 1. dc source gives whole circuit supply, and 3. 2. MCU be connected with digital to analog converter, and 4. 3. digital to analog converter be connected with power amplifier, and 5. 4. power amplifier be connected with ultrasonic transducer, and 6. 5. ultrasonic transducer face acoustic wave reflector.In the main program running of MCU in 2., random call is the subprogram of digitlization bat pulse ultrasonic wave wave beam, 3. this data signal is delivered to digital to analog converter converts analog signal to and strengthens amplification, 4. further amplify and promoted afterwards ultrasonic transducer 5. through power amplifier, 6. 5. ultrasonic transducer gone up the bat pulse ultrasonic wave beam transmission of restoring to acoustic wave reflector, the bat pulse ultrasonic wave wave beam of high emulation and then to all the winds propagation, thus simulate the extensive scene of preying on of a group bat.
Claims (3)
