Small electronic mosquito repelling device used in agriculture and livestock husbandry

Abstract

The invention discloses a small electronic mosquito repelling device used in agriculture and livestock husbandry. The device comprises a potentiometer, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, an eighth resistor, a ninth resistor, a potentiometer, a uni-junction transistor, a triode, a crystal oscillator, a first capacitor, a second capacitor, a third capacitor, a first diode, a second diode, a switch and a direct-current power supply. The device comprises a mosquito repelling circuit generating ultrasonic waves. The circuit structure is simple, and the manufacturing cost is low. A plurality of the devices can be placed in different corners, such that mosquitoes can be repelled comprehensively. The device is especially suitable for agriculture and livestock husbandry in relatively remote areas, and helps in providing a reliable culturing environment for farmers.

Description

technical field [0001] The invention relates to an electronic mosquito repellent, in particular to a small electronic mosquito repellent used in agriculture, animal husbandry and breeding. Background technique [0002] my country is a large animal husbandry country. Since the reform and opening up, the animal husbandry industry has developed rapidly, and the amount of livestock and poultry breeding and the output of meat, eggs and milk have greatly improved. With the development of the domestic macro economy, the market demand for livestock products is increasing day by day. Continuously improving, with the advancement of science and technology, the current agriculture, animal husbandry and breeding industry has also been greatly developed. In many remote areas of our country, there are relatively many mosquitoes, which greatly affects the breeding output and brings many agricultural households. Come the loss, most of today's electronic mosquito repellents are aimed at urban a...

[0002] my country is a large animal husbandry country. Since the reform and opening up, the animal husbandry industry has developed rapidly, and the amount of livestock and poultry breeding and the output of meat, eggs and milk have greatly improved. With the development of the domestic macro economy, the market demand for livestock products is increasing day by day. Continuously improving, with the advancement of science and technology, the current agriculture, animal husbandry and breeding industry has also been greatly developed. In many remote areas of our country, there are relatively many mosquitoes, which greatly affects the breeding output and brings many agricultural households. Come loss, most of today's electronic mosquito repellents are aimed at urban areas, with complex structures and high prices, which is not conducive to the development of agriculture, animal husbandry and breeding in these areas
