Description
Technical field
The invention belongs to application of electronic technology field, are about a kind of more satisfactory environmentally protective electronic insect-killing worm dress
It puts.
Background technology
The mosquito for stinging people is mostly the female mosquito of the upper ovum in bosom, and general hero mosquito does not bite people.Since female mosquitoes are in the cytula phase
Between need energy and protein, so seeking and biting warm-blooded animal, be generally unwilling to approach with male mosquito again.Female mosquito is once discovered
When fluttering its wings up and down the ultrasonic wave for sending out 21~23kHz frequencies to male mosquito, because female mosquito is extremely quick to the sound wave of 21~23kHz ranges
Sense, female mosquito will be avoided actively.
More satisfactory environmentally protective electronic insect-killing worm device of the present invention is sent out using the male mosquito of electronically simulation
The ultrasonic wave gone out, and human ear does not hear the ultrasonic wave that frequency is 21~23kHz at all.It is generated by imitating male mosquito alar part vibration
Sound, the ultrasonic wave energy that mosquito-driving device is sent out makes female mosquitoes be reluctant close to human body, drives what is mated by ultrasonic wave
Female mosquito, to achieve the purpose that avoid female mosquito bite people.Because the female mosquito of different regions has certain difference to ultrasonic frequency reaction
Property, thus mosquito repellent drive cockroach device send out ultrasonic frequency should be different, thus need adjust in the frequency of a certain sensitivity, with
Realization achievees the effect that drive in different regions mosquito and cockroach have it is relatively good.
The effect that ultrasonic wave of the present invention drives female mosquito is more stable, and ultrasonic acoustic wave human ear both do not heard or
Any influence will not be generated to human body, for Ultrasonic Radiation radius more than 10 meters, it is more satisfactory that ultrasonic mosquito dispelling, which drives cockroach device,
Environment-protecting articles.
More satisfactory environmentally protective electronic insect-killing worm device of the present invention described further below is in implementation process
Involved related technology contents.
Invention content
Goal of the invention and advantageous effect：More satisfactory environmentally protective electronic insect-killing worm device of the present invention is to utilize

Sound wave can be such that female mosquitoes are reluctant close to human body, and the female mosquito to have mated is driven by ultrasonic wave, and female mosquito bite is avoided to reach
The purpose of people.
Because the female mosquito of different regions or cockroach have the frequency response of ultrasonic wave certain otherness, therefore mosquito repellent drives cockroach dress
Certain difference should be had by putting the frequency for sending out ultrasonic wave, thus need to adjust in the frequency of a certain sensitivity, to realize differently
Area achievees the effect that drive mosquito and cockroach have it is relatively good.The radiation radius of ultrasonic wave of the present invention is more than 10 meters, ultrasonic mosquito dispelling
Drive cockroach dress
