There are thousands of ilcus for electric mosquitoes, can you hurt people?

It was the hottest time in summer. In the summer, in addition to the hot temperature, there is an unbearable thing, which is mosquito. Not only is blood -sucking and crazy big bags, the annoying mosquitoes must be buzzing in your ears. Every time I just fall asleep, there is a buzz of frustration in my ears. The accumulated drowsiness suddenly disappeared!

Xiaobian has been harassed by mosquitoes recently. Repeatedly several times a night, the mosquito did not hold it, but the sky gradually became bright! The nasty little flyworm is simply the natural enemy of human beings in summer!

Seeing this scene, did you feel hard?

In order to kill these annoying guys, people have invented many means of mosquito putting on the ground, simply including flies, slippers soles; mosquito coils and mosquito coils using chemical means; Harmony mosquito ester; mosquito nets that mosquitoes are thousands of miles ...

But Xiaobian wants to say that the most mosquito to get the most ingenious mosquito may still count the electric mosquito.

Not only can you "kill" mosquitoes, but the electric shock sound of "crackling" after hitting the mosquito is very qi, and the electric mosquito also has a high hit rate. So, how high is the use of high -voltage electric mosquitoes? Is such a high voltage dangerous to the human body? Today, let's talk about the electric mosquitoes to shoot those things.

Why is there such a high voltage for electric mosquitoes?

The voltage generated by the electric mosquito that we now use can usually exceed 2,000 volts. When the mosquito encounters such a high voltage, we will usually be directly coke by electrical death. So how does this voltage produce?

Electric Mosquito Source 丨 Wikipedia

The circuit inside the electric mosquito shot includes the oscillating circuit, the voltage voltage circuit, and the voltage voltage circuit. When the mosquito mosquito shoot switch is pressed, the DC voltage from the battery output is transformed by the oscillating circuit composed of the transformer and the transformer to ; The transformer voltage is enhanced by the transformer in the booster circuit to about hundreds of volts; the voltage voltage of the voltage circuit composed of diode and capacitors is then performed, and the high voltage above 2,000 volts can be obtained.

If you look at the electric mosquito used at home, you will find that they are generally composed of a three -layer metal mesh. The outermost two layers of metal mesh are not directly connected to the middle layer, and there is still a little distance between the two. In the middle connecting the positive electrode of the power supply and the circuit, the outer metal mesh is connected to the negative electrode.

At the same time, we know that the air has a breakdown (usually, the breakdown voltage of 2 mm air is about 1000-2000V). The so -called "breakdown voltage" refers to the voltage that causes the breakdown of the media. As far as air is concerned, the breakdown voltage is related to the humidity, temperature density and ingredients of the air. The voltage between the outer metal mesh between the electric mosquito shot and the middle metal mesh is usually not enough to reach the air's breakdown voltage, so the discharge phenomenon does not occur.

However, when the mosquito "cover" the mosquito "hood" into the two layers of metal mesh of the mosquito mosquito, the mosquito connects the outer metal mesh and the inner metal mesh as a conductor, and the mosquito is killed.

Have you found that the hit rate of electric mosquitoes is higher?

The mosquito's flight skills are very superb, and even raindrops can be avoided. Why is the relatively bulky electric mosquito shot higher than the flexible fly shooting rate?

You may think that "electric mosquito clam is charged, as long as you encounter mosquitoes, you can kill it," but this is only one aspect of the secrets of electric mosquitoes, and the reason for the high hit rate of electric mosquitoes is On electrostatic.

That's right, it is the static electricity of the glass stick adsorption of paper chips in physical experiments. When the electric mosquito is started, the ultra -high voltage will also form a static field between the noodles. When we wave the electric mosquito to the mosquito, the mosquito with a very low quality will be easily adsorbed by the electrostatic field. He hit the power grid and was electric to death.

If you find mosquitoes parked on the wall, you can start an electric mosquito, and use the noodle to approach the mosquito. At the same time, you can observe the trajectory when it takes off to see if it has the effect of being attracted to the noodles.

Of course, this effect requires that the mosquito is relatively close to the noodles before it will work. To some extent, it also plays the effect of preventing and controlling mosquitoes. In addition, this effect is even more obvious for more quality insects, such as cockroaches, flies and beetles.

If you accidentally touch the electric mosquito, will it shock?

Next is the question that everyone is most concerned about: Do you accidentally touch the electric mosquito shoot?

First of all: Don't touch it!

Everyone knows that the safety voltage of the human body is 36 volts, so the voltage of up to 2,000 volts at work at work will undoubtedly make people feel "very dangerous."

In fact, if you directly touch the electric mosquito shot in the work, the electrical mosquito shot of the three -layer network structure mentioned above is an example. The metal network of the outer layer will not be charged. It will not be charged. However, in the actual operation, it may be accidentally electric due to the aging hair, electric mosquito beats, and other unknown factors. In addition, some electric mosquitoes may also be charged due to different structures, so do not touch it. In addition, be careful not to close the charged mesh closer to others.

However, the current of the electric mosquito is very small, so even if you are not careful, there will be no life danger. This can still be assured (but it will be very painful).In addition, there will be residual electricity on the grid after the electric mosquito is used, so when you accidentally touch it, you will feel numb.There are also this kind of single -layer electric mosquito shot in the picture, so don’t touch it

However, it should be noted that the electric shock brought by the electric mosquito can affect the work of the pacemaker. In addition, people with other basic diseases such as epilepsy should also be careful of the electric shock brought by the electric mosquito.

All in all, electric mosquitoes are still a safe and reliable mosquito -extinguishing tool for the general public. As long as you choose an electric mosquito shot from a reliable manufacturer, you can rest assured that they can hold them to find mosquitoes to "revenge".
