An efficient environmentally friendly electronic fly disinfestation

Abstract

The invention discloses an efficient and environment-friendly electronic fly killing device which comprises a power source, a light-emitting diode, a button switch, a first resistor, a second resistor, a third resistor, a fourth resistor, an audion, a transformer, a first capacitor, a second capacitor, a third capacitor, a first diode, a second diode, a third diode and a metal net. A high-frequency oscillator formed by the audion and the transformer is electrified to work, a 500V high voltage is generated on a secondary coil of the transformer, and an indicator light circuit is formed by the light-emitting diode and a current-limiting resistor and used for indicating the on-off state of the circuit and displaying the consumption conditions of the electric energy of a battery. According to the efficient and environment-friendly electronic fly killing device, the audion and the transformer enable a 3V direct current to be converted into an about 18kHz high frequency alternating current, the secondary coil of the transformer rises the voltage of the alternating current to the 500V high voltage to be applied to the metal net of a fly pat, when flies touch the metal net, the flies will be burnt, shocked or killed by the current or electric arcs, and the fly killing device has the advantages of being efficient, healthy, not prone to causing pollution and low in manufacturing cost.

Description

technical field [0001] The invention relates to a fly killer, in particular to an efficient and environment-friendly electronic fly killer. Background technique [0002] Flies are harmful to humans because they carry a variety of pathogenic microorganisms. The body surface of flies is hairy, and the gripping pads on their feet can secrete mucus. Pathogens such as Vibrio cholerae, Salmonella typhi, Shigella, Hepatitis bacillus, Poliomyelitis bacteria, Hepatitis A bacteria, Hepatitis B bacteria and roundworm eggs often stay on the human body, food and tableware. The habits of the body, the pathogens attached to it will soon contaminate food and tableware, the prevalence of cholera, dysentery and bacterial food poisoning are directly related to the spread of flies. Slapping is inefficient, unhygienic, and the use of drugs to kill flies is easy to pollute and expensive. Contents of the invention [0003] The object of the present invention is to provide an efficient and envi...
