Abstract
The utility model relates to an electronic ultrasonic mouse expeller which consists of a power-supplying power supply DC, a unijunction transistor oscillating circuit, an ultrasonic signal amplifying circuit and an energy converting circuit. The electronic ultrasonic mouse expeller is characterized in that mice communicate in an ultrasonic way, and the auditory system of the mice is quite developed and is quite sensitive to ultrasonic waves. Test results show that the mice are particularly sensitive to the ultrasonic waves of 30-40 kHz, and the mice are harsh and intolerable to listen to the ultrasonic waves generated by the electronic mouse expeller, so that the heads of the mice are unconformable and the mice want to flee a scene impatiently, and the mice have symptoms of anepithymia, apocleisis, hyperspasmia and the like due to horror, and even die, thereby finally expelling the mice from homes, production places, life places and the like. As responses of the mice in different areas to the frequency of the ultrasonic waves are different to some extent, the frequency of the ultrasonic waves sent by the mouse expeller is in a certain range during design, namely, the sent ultrasonic waves are scanning type ultrasonic waves and are not fixed in certain frequency, thereby having a better mouse expelling effect.
Description
Technical field
The utility model belongs to the application of electronic technology field, is about a kind of electronic type ultrasonic rat repellent.
Background technology
Mouse is linked up with the ultrasonic mode, and the auditory system of muroid is very flourishing, and is very responsive to ultrasonic, can accurately judge the source of sound in the dark.Result of the test shows: mouse is responsive especially to the ultrasonic of 30～40kHz, ultrasonic rat destruction, protection against rodents or to kill mouse be exactly these characteristics of utilizing mouse.It is ear-piercing hard to bear that the ultrasonic that the electronic type mouse driving device is produced can let mouse listen; Make its brains uncomfortable; Make it too impatiently want to flee the scene; Make symptoms such as it is lost the appetite lest being afraid of, apocleisis, tic, even cause its death, finally reach and mouse expelled places such as household, production, life.If force mouse to be in all the time in the ultrasonic environment, the ultra-high frequency ripple that the sounding body of mouse driving device sends can stimulate mouse, can disturb and destroy muroid nervous system, the sense of hearing and physiological system, makes the purpose of its physiologic derangement to reach rat destruction, to kill mouse.
Rat destruction, the protection against rodents effect of the described electronic type ultrasonic rat repellent of the utility model are more stable; And it is nontoxic, harmless, radiationless; Can not cause secondary pollution to environment; 46 decibels of intensity of ultrasonic acoustic wave are lower than normal human's acceptance value, and people's ear was not both heard and human body is had no influence, can more effectively solve mouse and suffer from problem.
Reaction has certain otherness to ultrasonic frequency because of different regional mouse; So when design, make mouse driving device send frequency of ultrasonic certain limit is arranged; That is: what mouse driving device sent is the sweep-frequency B ultrasonic, rather than is fixed on some frequencies, thereby rat destruction has reasonable effect.
Below specify this electronic type ultrasonic rat repellent related relevant technologies in design, manufacturing process.
