How to make an electric fly swatter at home. Siberian fly swatter. How the device works

This device is designed for effective and quick control of domestic insects.
The store product (A), as a rule, is a handle and a working surface attached to it rectangular shape. They come from different materials. The simplest is all plastic. Sometimes there are rubber ones with a metal rod in the handle.

It works simply. We take the handle in our hand and use the working surface to hit the fly, mosquito, cockroach, centipede, bedbug and other uninvited insects.
The most interesting homemade fly swatter (B) is a handle, 10-15 mm in diameter, made from a straight tree branch (1) and a rubber striking surface cut from a car inner tube (2), round or rectangular in shape with a tail like this (3).
The branch is split (4) and this tail is inserted into the gap. The top is wrapped with (5) thread, twine, rope.
Everything would be fine, it works, but there are difficulties.

The fact is (C) that the solid, working surface of the flapper, when approaching the surface of the wall, along with the air, literally pushes out the insect (D). This especially applies to mosquitoes. Therefore, you have to hit the insect very hard. As a result, a smeared spot remains on the wall, ceiling or furniture, which spoils the surface, for example, a crushed corpse is simply absorbed into the ceiling. And if the mosquito was “bloody”, drunk and swollen with blood, it leaves a stain that is difficult to wash off.
I thought for a long time about how to make a fly swatter free of these shortcomings. I remembered how, as a child, in the garden, I came up with the idea of fighting white butterflies, pests of cabbage. I found a thick branch without leaves and knocked down butterflies right in the air. The air whizzed through the dense interweaving of twigs, but the insect did not. But a fly or mosquito needs a very thick branch, and there are no such branches.
What if I made a work surface from a fine mesh, it dawned on me recently? Well, that is, I have seen industrial fly swatters with holes in the working surface, but there were very few holes, or they had a relatively small surface.

I hastily made the first prototype (6).
Here I also took a branch (7) of an apple tree. I bent the frame (8) from steel wire with a diameter of 3 mm. Covered it with metal, mosquito net(9). In such a way that the mesh protrudes somewhat (10). I simply turned up the edges of the mesh until it holds, although it is pricked by wires; ideally, fasten it with thin wire.
The frame itself was tied to the branch with fishing line.
I was delighted when the first swat on the mosquito was a success. Works! It’s so nice when an invented device immediately justifies the time and effort spent!
You don’t have to hit it too hard with this cotton swab; I rarely fly mosquitoes out from under it. There are practically no stains left. You can even get the hang of shooting down insects in flight!
Actually, it can probably be improved. For example, use a frame made of insulated wire or a plastic rod. Try installing a nylon mesh itself. If I get around to it, I’ll do it and publish it.

How to escape from annoying insects during a picnic or in the apartment? There are many recipes and methods, but not all of them are simple and convenient.

Electric fly swatter– an innovative device that allows you to quickly and without special effort destroy mosquitoes, flies, horseflies, wasps and other “troublemakers.”

What is an electric fly swatter and how does it work?

An effective device for combating flying aggressors looks like a regular badminton racket. The main difference is that instead of the usual strong fishing line on plastic case taut metal grid.

This material is there for a reason. It passes through thin twigs electrical discharge, killing insects. Electric field, created above the surface of the racket, leaves no chance for a fly, a mosquito, or even a bumblebee.

There is an LED flashlight on the handle. The backlight helps you hunt for insects in the dark.

How to use the device

There is nothing complicated. Here's what to do:

Press the button located on the handle, turn on the device and touch the mesh with the stick. Do you hear a characteristic crackling sound? Everything is fine, the miracle racket works.
If there is insufficient lighting outside or in the room, immediately turn on the flashlight using another button.
Make a few strokes of the racket in the place where you notice the insect. Perhaps you can’t see it well, you can only hear a nasty squeak? No problem, wave boldly and the mosquitoes will fall into the trap.
When a fly or other insect gets stuck in the mesh, press the special button. Immediately on metal surface a discharge is given, small insects die. and the bumblebees are only stunned and fall to the ground. You will easily destroy them.

You see how easy and simple everything is! Not even one tiny insect will not escape the miracle racket.

The device will not cause harm to humans or pets. Of course, you need to protect the electric fly swatter from the attention of small children who strive to taste all the objects.

Customer Reviews

Many people have already purchased this simple and effective device. What do buyers think about the electric fly swatter?

Anya, Moscow

“I read the description of the new device on the Internet and immediately thought that this was another publicity stunt. I asked my husband for advice. He said that the process described in the instructions is quite realistic.

I bought a miracle racket. Works great. You sit, wave at her, and the mosquitoes “fry” without any problems. A good thing. I recommend."

Andrey, Ekaterinburg

“I saw this thing at my neighbors’ place. They said it copes well with flies. I bought it and gave it to my wife. It turned out to be a really effective device. If there are a lot of midges, you don’t have to give a shock every time. Press the button immediately and swing the racket. The grid will be constantly energized.”

Ivan Arkadievich, Tula

“In the summer I live at the dacha. Insects sometimes get to you. My daughter brought me a device that resembled a simple badminton racket.

Now I don’t know grief. In the evening, in the gazebo, I swing a racket, fortunately it is very light, mosquitoes die instantly. I'm glad that food requires regular AA batteries. The electric fly swatter is charged from 220 V.”

Elena Andreevna

Is it possible to make a miracle fly swatter yourself?

Some home craftsmen disassemble a device that destroys insects using electrical discharges and try to create a similar one. homemade device from improvised means. Parts from old TVs, power supplies, electrodes and other parts are used.

An inquisitive mind is a great thing, but in the case of an electric fly swatter, experimentation is inappropriate. They can end badly.

Some would-be experimenters try to give advice on how to make an electric fly swatter with your own hands. But at the end of the description of their experiments they always add: “Do not repeat this experiment! Potentially life threatening! Useful thing though to catch a lonely one annoying fly It’s not that easy – you’ll have to jump. You also need to be careful not to grab the fly swatter wet hands, and during the fishing process it is better that no one hangs around.
Question. Is it safe to use a fly swatter for people with an implanted pacemaker?

I work in a cafe, and we have electric fly swatters hanging in our kitchen. This:
firstly, it’s convenient (adhesive tapes are a thing of the past, they ruin the whole appearance kitchen);
secondly, it is hygienic. The likelihood that the corpses dead insects will fall out from there is zero.
I can’t imagine how craftsmen manage to make such things from improvised means, and why? The market offers big choice for every taste and budget.

Radio circuits for domestic use

Summer is a wonderful time and many people try to spend this time of year summer cottages. And everything would be great if it weren’t for the annoying insects...

In general, there are many various means protection against insects includes various electronic repellers and chemical sprays, but Lately the so-called electronic traps. The operating principle of such a device is extremely simple metal mesh with connected to it high voltage, upon contact with which insects die from an electrical discharge.

Here we will look at such a device.

Electronic insect trap circuit

At the very beginning, a small disclaimer: in the original article (and it was taken from the magazine " Young Technician") a light source serves as a “bait” for insects. As such a source, it was proposed to use an LDS-20 fluorescent lamp according to the “without starter” scheme, and it is this scheme that is shown in the figure. But you can do it much simpler - use the most ordinary energy saving lamp and then the scheme will be much simpler.

So - the design of the device

As everyone has already guessed, the lamp attracts insects with its light, arriving at which they fall between two grids surrounding the lamp and which are under high voltage. In addition, the heat generated by the lamp also attracts insects.

To power the lamp daylight a voltage multiplier is used, which rectifies the mains voltage to approximately 600 volts (no load). The upper arm of the multiplier (capacitor C1, diodes D1, D2) charges capacitor C3, and the lower arm (capacitor C2, diodes D3, D4) charges capacitor C4. The upper capacitor is charged with negative voltage, and the lower one is charged with positive voltage. Since capacitors C3 and C4 are connected in series, the voltage across them adds up and becomes sufficient to ignite a fluorescent lamp, and the current strength allows it to be kept burning. In such a lamp power circuit, you can use both backlight lamps from the monitor and fluorescent lamps with burnt-out filaments.

As a high-voltage source, everything is also very simple: here a high-voltage coil from an automobile ignition system of type B116 or similar was used, in this case its high-voltage output is the upper output of transformer T1 in the circuit. In general, instead of an ignition coil, you can use a homemade transformer wound on a piece of 400NN grade ferrite rod with a length of 80 mm and a diameter of 10 mm. The primary winding contains 30 turns of PEL-0.6 wire, the secondary winding contains 1500 turns of PEL-0.08 wire, winding in 10 layers with careful insulation between the layers, but, you see, with a coil everything is much simpler!

Here, in fact, is the diagram itself:

From the rectifier (diode bridge D5...D8), a pulsating voltage with a frequency of 50 Hz is supplied to a voltage converter made of dinistor VD1, capacitor C5 and resistor R2. The load of the converter is the primary winding of transformer T1.

The voltage converter works as follows. Capacitor C5 is charged through resistor R2 with a pulsating voltage, and as soon as the constant voltage on the capacitor reaches approximately 80 volts, dinistor VD1 will open and capacitor C5 will quickly discharge through primary winding transformer T1. Such a converter is called a relaxation generator. In his circuit, the resistance of resistor R2 is selected in such a way that the current flowing through it will not keep the dinistor open after the capacitor is discharged, therefore the dinistor will close and the process will repeat. The operating frequency of the converter depends on the parameters of the elements R2, C5, as well as on the operating voltage of the dinistor VD1, and in this case it is several hundred Hertz. Since the number of turns secondary winding transformer T1 is many times larger than the primary one, then the pulse voltage on it will be much greater, reaching several kilovolts.

Capacitors C1..C4 must have an operating voltage of at least 380 volts, capacitor C5 - at least 750 volts. Instead of a diode bridge (D5...D8), you can use diodes like KD208A, KD212A or similar.

High-voltage grids with a cell with a diameter of approximately 10..20 mm must be placed around the H1 lamp so that they form two cylinders, the distance between these grids should be slightly greater than the distance at which electrical breakdown occurs. For safety, the outer mesh of the trap must be connected to the ignition coil housing. The diameter of the internal grid must be sufficient to prevent electrical breakdown between the grid and the H1 lamp.

Every person who spends time in the country knows what an attack by flies, mosquitoes and other flying insects is. Often, desperate to completely get rid of annoying animals in the house with the help of insect repellents, many summer residents resort to good old fly swatters. But they do not always give the desired effect, leaving stains from killed flies and mosquitoes on surfaces throughout the house.

A reliable electric fly swatter from the Aliexpress website will come to the aid of summer residents, destroying insects as soon as you touch them electrical surface, and at the same time absolutely safe for people and pets.

Principle of operation

An electric fly swatter resembles a tennis or badminton racket in appearance. It has a handle and head, just like a regular fly swatter. There is a cover on the handle that hides two small batteries that power the “gadget.” The head is equipped with a three-layer mesh of metal electrical rods.

To destroy a fly or mosquito, you just need to wave the head of the fly swatter towards the insect. The slightest touch will give it an electric shock. Working surface The fly swatter is large enough, and thanks to this you can kill several insects at a time.

Main characteristics of the product:

two layers of protection for pets and humans;
The set includes economical batteries, one charge of which is enough for 600 strikes;
power of 3800 V at the moment of electric shock;
the ability to kill a mosquito or fly sitting on a person without harming the latter;
presence of light indicators;
warning about low batteries by turning on/off a special indicator.

Advantages of an electric fly swatter over a conventional one:

Does not leave marks on the surface.
Much more effective due to the fact that a light touch to the insect is enough.
Suitable for outdoor use.

The price of a fly swatter on Aliexpress is 294 rubles, while in domestic country goods stores its cost is set between 500 and 1000 rubles.

Numerous positive reviews buyers testify high quality product and its effectiveness in controlling flying pests. Based on this, we can conclude that the price-quality ratio is most optimal in the Aliexpress hypermarket.
