DIY fumitox repair

It's a shame when in the middle of summer the fumigator (a device for repelling mosquitoes) breaks down, you come to the store, and there they say that everything that was sold out, and new ones will be brought in next year. In this case, the broken fumigator has to be repaired by hand.

The main breakdowns of fumigators are two: 1 - wire breakage (in models of fumigators with rotating plugs), 2 - heating element burnout. In 95% of cases, a resistor serves as a heating element in fumigators.

To access the resistor for replacement, it must be removed from the ceramic substrate (heating plate and / or bulb wick). It is located under a layer of some kind of solidified sandy-clay mixture. The mixture is picked out very easily with an ordinary knife or screwdriver.

I do not recommend using a one-watt resistor as a heating element for a fumigator (it was not in vain that it burned out). Moreover, a two-watt resistor can be placed in the hollow of the substrate without any obstacles. To select the resistance of the resistor, I measured the resistance on a similar fumigator. It was 10k, but at the same time, the fumigator consumed not 3 watts (as it is written on the body), but as much as 5. This is almost 2 times more, therefore, repelling plates and liquid (in other models) are consumed twice as fast. The use of a 15k resistor made the fumigator less power hungry, and its consumption began to match the declared 3 watts.

You can use a teaspoon of gypsum plaster or tile adhesive to fix the heating resistor to the substrate. If you use glue, then it will be almost impossible to replace the resistor again. Before using the repaired fumigator, wait until the new "putty" is completely dry. This time will take 7 to 12 hours, depending on environmental conditions and application layer.

The electrofumigator burned out.
There is a tiled plate with a depression. A resistor is inserted there and some kind of garbage resembling cement with sand is sprinkled on top.
see photo
This resistor burned out. It burned out because there was poor thermal contact with the tile plate.
Well, the resistor itself was a bad carbon one. (The Chinese do not know how to make resistors!)

The question means this: How to make cement correctly. So that there is a normal thermal contact and so that there is electrical safety.
Who repaired the fumigators? Share your cement recipe?

Try liquid glass - a common silicate glue that is also used when repairing soldering irons. Apply, heat. With rapid strong heating, it foams, but it performs its functions.

Silicate glue + talcum powder + quartz (grinded in a mortar) sand.

I have a feeling that for storing the above picture, the forum owner will pay more than the new fum cost.

Probably, it will be easier and cheaper to buy a new one and immediately build a capacitor into it to reduce the current. It still works for me after that: https://my.housecope.com/wp-content/uploads/ext/1366/it-works!/1693-4/2006/07/27/20-07-28/

One of the first lives with me, still without a hole for a bottle
it’s too lazy to take it out of the socket all season and it warms up - we knew how before
Chinese people are things to do!

It is useless to buy a new fumigator as it will burn out just like this one.
One is already lying around broken. He has a heating element - a conductive track.
The one that is now easier to restore. I will put there 2 resistances of 0.5W each just enter.

The problem is what to fill.
silicate glue will likely crack over time.

If pure cement? Well add a little sand
And why do you offer exactly quartz sand? Where can I get it?

Quartz sand (or the like) is covered with powerful fuses. A similar recipe was used to insulate the tip of a homemade soldering iron.
Of course, the price of such a fuse is much more expensive than a fumigator. It's up to you what to do next.
The two fumigators that I use have been in operation for three seasons. There are no resistors in their design. The heater is made in the form of a graphite-like track. The cost of such a device is equal to the cost of a loaf of black bread.

Alex s: And why do you offer exactly quartz sand? Where can I get it?
–
Coef. thermal expansion of quartz is minimal. Therefore, cement with it
less cracking.
–
Quartz sand - usually taken from the river bank.

alabama3: Quartz sand - usually taken from the river bank. Or they buy from suppliers, for example here

And I didn't bother with the sand. After the Chinese rezik burned out, he took the “bulbulator”, counted the denomination and put 15 kOhm MLT-1 (or MLT-2, in general, what he found in the nightstand), filled it with Knauf gypsum putty - it remained after working with drywall. There was still not enough quartz sand to spend on this craft.

It would seem that the 21st century is in the yard, humanity with might and main is mastering the cosmic expanses, while it can not cope with mosquitoes!

Neither mosquito nets, nor sprays, nor bracelets help.

Of course, today there are many modern and expensive devices - fumigators, mosquito repellents and exterminators, but sometimes even they are unable to cope with adversity.

We will tell you how to do it yourself to scare away mosquitoes ...

• Dark plastic 2 liter bottle
• Cutter
• Awl
• Thick wire
• Dry yeast bag
• Half a glass of sugar
• A glass of warm water

1. Take a dark plastic bottle, cut off the top of it - about one third.

2. At the top, remove the lid - we have a funnel.

3. We insert our funnel inside the cut bottle.

4. With the help of an awl we make two holes along the edges.

6. Fix it on both sides - the mosquito trap is ready! Now it's up to the bait ...

7. Mosquitoes react to carbon dioxide and heat that is released ... when yeast ferments. Therefore, pour about 5 grams of dry yeast into a bowl.

8. We measure out half a glass of granulated sugar.

10. And add a glass of warm (not hot!) Water to our mixture, the temperature of which is about 30 degrees.

12. Mix our mixture well.

13. And pour it into the bottle. The main thing is that the mixture does not reach the neck. Now mosquitoes, attracted by the carbon dioxide and heat that ferment yeast, will rush to our trap. Once inside, they can no longer get out. The bait in the trap should be changed every two weeks. This trap can also be used for wasps and flies by adding a little sugar syrup or jam instead of the yeast mixture.

You can decorate our trap with a spectacular "skirt".

Today, you can buy a fumigator in almost any store that will protect you from mosquito bites. However, if you did not manage to acquire it, but you need to save yourself, try to make a fumigator with your own hands.

This device is quite simple in design and consists of:

• Plastic case;
• A heating element, from the heat of which the insecticide evaporates;
• A container or tray for an insecticide in liquid or tablet form;

• Plugs for connecting the device to the mains.

If you have at least a basic understanding of electronics, you can assemble a mosquito fumigator with your own hands from available tools. First you need to find a heating element. Radio amateurs often have in stock small-sized wirewound resistors with a power of no more than 25 watts. They are ideal for heating, for example, cardboard soaked in insecticide. In this case, the cardboard is placed directly on the resistor. However, it is a very dangerous do-it-yourself fumigator against mosquitoes, as the material can flare up.

If the knowledge of physics and electronics is not enough, but there are tablets for an industrial fumigator at hand, you just need to heat them up. The result is an analogue of a pyrotechnic fumigator, better known as a mosquito coil. It smolders and gives off a mosquito repellent smell.

To make such a pyrotechnic fumigator out of a plate, heat it over a candle or even a lighter flame, then blow out and smolder on a saucer. However, this method is dangerous by possible ignition of the plate and is suitable only for field conditions.

A safer way is to place the plate on a burning table lamp, on a heated iron soleplate, or on a hair curling iron.

If there are no tablets, you can take a liquid that repels mosquitoes with its smell and heat it to evaporate the smell. A regular aroma lamp is suitable for this.

It is not so easy to make a plate with an insecticide, because in addition to chemical impregnation, a long-smoldering base is required. It is much easier to make your own fumigator liquid. It can be poured into an industrial fumigator flask or used in an aroma lamp.

The simplest recipe is 100% eucalyptus extract. Only the extract is needed, not the oil.

But oils from other plants can help, for example, tea tree, citronella, and clove “ethers”. They can be easily heated to evaporate the odor over a candle flame. However, you cannot pour pure oils into an industrial fumigator; you need to prepare a solution from a liter of water, a teaspoon of salt and two tablespoons of vodka (for better dissolution of the oil). Add 10 drops of essential oil to this solution. Pour part of the solution into the fumigator flask, and the rest can be sprayed from the spray bottle around the room.

The fact is that the fumigator is in normal condition, but does not pass electricity through the ceramic plate and therefore does not heat up. How can this plate be restored?

It's a pity to throw it away, in good condition, but we are not very rich to waste money.

The presented fumigator costs 50 rubles. These are 2-3 trips by minibus. All such devices are made in a disposable version and are meant to be thrown away in the event of a breakdown, like most household appliances. Clinical hoarders and do-it-yourselfers can certainly waste a lot of time repairing such nonsense. But during this time they could earn much more than they save on repairs.

There is a mosquito fumigator in almost every home in the summer. It is difficult to imagine an easier way to bait annoying insects. However, there are situations when the factory device has failed, or the liquid in it has run out, and there is no way to purchase it at the moment. There are several ways to make your own mosquito fumigator liquid.

Fumigation is understood as the poisoning of insects with poisonous fumes. The devices used for this purpose are called fumigators.

A standard liquid that is purchased in stores contains predominantly chemical components. When heated, they evaporate and poison flies and mosquitoes. At home, it will not be possible to recreate the formula of an industrial insecticide. Homemade liquids work on the scare principle. Mosquitoes have an excellent sense of smell and there are a number of repellent odors.

If you run out of liquid, the most effective and simple remedy that can be poured into the fumigator is eucalyptus oil. To enhance the action, add 5-6 drops of clove oil. In terms of cost, the natural drug is ahead of the factory version. The purchase of a 15 ml bottle of essential oil will cost 75 rubles, while a 30 ml fumigation liquid costs 100 rubles. But unlike the latter, using eucalyptus extract does not have to inhale chemical components, and the remedy itself also has a calming, antiviral effect, helps to eliminate headaches.

In the absence of a fumigator, a piece of cotton wool will perform its functions.It is enough to moisten a cotton pad with a small amount of eucalyptus oil and place it near a window or other sources of mosquito infiltration.

You can make a mosquito liquid for a fumigator from essential oils, an extract, an extract or tincture of the following plants:

To prepare a mosquito repellent solution, you should use a proven recipe: mix 100 ml of water, a few drops of tea tree oil, eucalyptus, lavender. It is not forbidden to add other aromatic components. Often, medical alcohol or vodka is used as a base.

The prepared liquid substances are not only poured into fumigators against mosquitoes, but are also used as sprays for treating the body, head of the bed, window frames, clothes, home textiles.

The mixture is made from dried herbs, apple cider vinegar. To prepare it, you will need the following components:

• rosemary;
• peppermint;
• thyme;
• sage;
• lavender;
• apple cider vinegar 500 ml.

Take a handful of each of the herbs and place them in a glass container. Pour vinegar over the dried collection and leave for 1-2 weeks. Shake the infusion periodically. Strain the aged solution. Refrigeration recommended. Before use, the mixture is diluted with water in equal proportions. The tool is used as a liquid for a fumigator or for treating mosquito bites.

Vinegar is used in combination with shampoo as a repellant.

The fumigator consists of several elements:

• frame;
• plug for connection to the mains;
• small-sized heating element;
• tray for insecticidal plate.

A wire-wound resistor is used as a heating element, the power of which does not exceed 25 W. A piece of cardboard soaked in an insecticidal liquid is placed directly on the resistor. However, this manufacturing method has many disadvantages. The most important of these is the fire hazard. And the process itself is quite painstaking, it requires knowledge of physics and specific skills.

To make a do-it-yourself mosquito fumigator, there are simpler and more affordable ways for everyone:

• heat the sole of the iron, curling iron or cast iron pan and place a plate on it;
• take a saucer or a small metal container, put a plate against mosquitoes in it, set it on fire and blow it out in such a way that it only smolders - such a pyrotechnic structure cannot be left unattended;
• The aroma lamp can also act as a mosquito fumigator.
• make a lemon and clove repeller.

If you have to escape from mosquitoes and midges in nature, then you can throw spruce branches, cones into the fire, arrange metal cans with smoldering wormwood, mint, wheatgrass.

Fumigator can be made by yourself. Perhaps the most difficult thing is to make a small-sized heating element. The easiest way is to use a wire-wound resistor of the C5-35V (PEV) type with a power of 25 watts as a heater. A dozen or two of these resistors can always be found in an amateur radio "box with trash". The smelly cardboard is placed directly on the surface of the resistor.

Experiments have shown that for normal evaporation of the cardboard substance, it is necessary that a power of about 12 W be dissipated on the resistor at an air temperature of 20 ° C. Based on this, the voltage supplied to the resistor is calculated.

Resistors with a resistance of 3.9 kOhm or 4.3 kOhm can be connected directly to a network with a voltage of 220 V. A resistor with a resistance of 2 kOhm can be connected to the network through a rectifier diode. A 13 ohm resistor is suitable for car fumigator .

But what if there are resistors of other ratings? You can, of course, connect them to the network through a matching transformer. However, making a transformer is difficult and troublesome. It is much easier to connect the resistor to the network through ballast capacitor... Resistor R2 is needed to remove the residual charge from the capacitor after turning off the power.

Ballast capacitor capacity

can be calculated using the formula:

R1 - heater resistance, Ohm,

P is the power dissipated on the heater W It is curious to note that the function C (R) has an extremum. The values ​​of the capacitance of the ballast capacitor for resistors of different denominations, as well as the values ​​of the voltage across the resistor are given in the table. The capacitance of the capacitor is selected by measuring the voltage across the resistor.

The device can use non-polar capacitors with a maximum allowable voltage of at least 350 V. The designations given on the capacitor cases generally refer to direct current. The maximum permissible alternating voltage is usually half that, it depends on the type of capacitor, the frequency and the shape of the voltage. Experience has shown that paper capacitors rated for 350 V withstands sinusoidal 220 V mains voltage well.

The design of the fumigator should be such that the heating resistor does not come into contact with fusible and combustible materials.

Summer is wonderful. But there is something that darkens the joy of this wonderful time a little. These are mosquitoes.
Nasty bloodsuckers itch and bite. At a picnic, by the sea, in the park. Why, sometimes they even seep into houses.

Many mosquito repellents can be found today. They take up entire shelves in supermarkets.
But I really don't want to apply aggressive products on my own skin. And it is clear to the child - not only mosquitoes will suffer.

It is much wiser to use natural mosquito repellents. You can cook them with your own hands.

A harmless and very pleasant way to protect yourself from annoying mosquitoes is available to everyone. For this you need a lemon and a clove.

The options are:
1. Slightly mash the lemon so that it gives juice. Poke a clove into a lemon, as shown in the video. In addition to fighting mosquitoes, it serves as a decoration and flavoring :).
2. Squeeze the lemon juice into a glass and pour the cloves into it.
Mosquito repellent must be placed next to the bed and you can safely sleep, even with an open window.
