I saw a link on **, which is called Ansu mosquito fish or something, it doesn't seem to be an electromagnetic principle, or put mosquito coils in it, but it is powered by batteries, not AC power. I'm the same as you.,It's on the subway that I always see this advertisement before I'm attracted to it.,I don't feel like the effect is good.,Search for this on ** is: Japan Ansu mosquito fish battery mosquito repellent set。
-
If you want to buy it, I can help you find it after May Day, and not only the Ansu battery mosquito repellent you said, but also ultrasonic electronic mosquito repellent, radar electric mosquito coils, etc. can be easily found.
Give it the best, I'll get it for you!
-
Ansu is the best brand? How to advertise with monks?
-
I'll tell you! Vanguard has it for sale. But the effect is not so good, I also bought it after seeing it on the bus, I used it for 3 nights, the effect does not feel good, the text Zhao Fei is correct!
And it's not a battery mosquito repellent, it's just battery-powered. Also change the tablets.
-
It's sold in big supermarkets I also bought one in Jusco today.
LZ can go and find it.
will send a spare machine...
-
It is sold in major supermarkets, and there are several Carrefour supermarkets in Nanshan.

Electronic mosquito repellent is ineffective.
Why do many sonic mosquito repellent devices advertise "ultrasonic mosquito repellent"? In fact, there are "ultrasonic mosquito repellents" on the Western market, but they are imitating the sound of bats. Bats use ultrasound to locate their prey.
In order to resist the predation of bats, some insects have evolved organs that can recognize ultrasound waves, and they can escape after hearing the sound of bats.
Let's say those electronic mosquito repellent that mimics bat ultrasound really works. The frequency of sound waves emitted by bats is at least above 10kHz, and even higher than 100kHz. Therefore, if these "mosquito repellents" are effective, they must be able to emit sound waves that contain ultrasonic frequency bands.
For the human body, prolonged ultrasound in large doses may cause damage to human cells.
Sonic mosquito repellent itself has never been proven effective, and some products in order to create a mosquito repellent effect, will make a "buzzing" sound, this method is not only funny but also very annoying, otolaryngologists said that the human ear is in the "buzzing" and other monotonous sounds for a long time, easy to produce irritability and physical discomfort, and even lead to tinnitus.

The electronic mosquito repellent is very easy to use, and the purchase method is as follows:
1. Choose products produced by regular manufacturers, quality-clear, chemical-free, environmentally friendly, pollution-free, parents should not be greedy for cheap and choose poor quality "three no products", so as not to have adverse effects on the baby's health caused by inferior products.
2. In addition, the product model, rated voltage, rated power, implementation standards, whether there is a certification label and other information also need to be paid attention to.
3. Choose a multi-frequency electronic mosquito killer, which can emit sound waves of different frequencies to effectively drive away a variety of mosquitoes, and choose a product with a volume adjustment switch, which can increase the volume and enhance the mosquito repellent range when you are outside. Turn down the volume when you go to bed to avoid affecting your sleep quality.
4. Choose the electronic mosquito repellent used by the baby, quality is the key, and the inferior electronic mosquito repellent shell plastic is often made of secondary plastic, which is easy to release toxic substances and affect the baby's health.
5. In addition, it is easy to have too high frequency, which has a great impact on the baby's auditory development. Therefore, parents must choose products with good quality when purchasing electronic mosquito repellents, and choose the corresponding functions according to actual needs.

The electronic mosquito repellent works well and is highly recommended.
After research, many data show that the most fierce mosquito bite in summer is the female mosquito during pregnancy, at this time the female mosquito will avoid the male mosquito, using this feature, the design of electronic frequency conversion line, so that the mosquito repellent produces ultrasonic waves similar to the male mosquito flapping wings, to achieve the purpose of driving away the female mosquito.
The mosquito repellent emits a rhythmic "dripping" sound, which uses high-tech circuitry to simulate the sound of male mosquitoes and dragonflies fluttering their wings, based on these basic principles of biology and bionics.
At the same time, these two sounds are combined into a special ultrasound wave that allows mosquitoes to flee when they hear the sound. Because the frequency of ultrasound is constantly changing in a large range, it can adapt to various mosquitoes and insects, and will not make them "adaptable" and "immune", and there is no harm to the human body.
Mosquito repellent is synthetic. The electric mosquito repellent is simple in structure, cheap and effective, which is the conclusion that consumers have reached in use for many years. The electric mosquito repellent has been upgraded, and the structure has become complicated.
Although some consumers said that it had no effect at all, most consumers said that the effect was still there.

The electronic mosquito repellent is still very good, the machine in the electronic mosquito repellent is equipped with energy-saving function, which can effectively use the battery, save electricity and save energy, and the tablets are fragrance-free, will not produce substances harmful to human health, convenient and energy-saving.

Electronic mosquito repellent is easy to use. The mosquito repellent effect is achieved by generating different sound waves unique to the mosquito repellent. Moreover, the electronic mosquito repellent is intelligent and environmentally friendly, and has low requirements for the application of environmental conditions, and has high utilization value.
-
I think the electronic mosquito repellent is easy to use: 1. It will not smell as strong as traditional mosquito coils; 2. Preferential treatment, long service life, no need to replace frequently; 3. Small size, does not occupy space.
-
The electronic mosquito repellent basically works, because the frequency it emits is to imitate the sound wave of the male mosquito to drive away the female mosquito, the male mosquito does not bite, and the female mosquito bites, but the voltage must be guaranteed in use, because the voltage is low will change the vibration frequency of the machine, and the working current and other parameters, so it is better to use a stabilized power supply, and the mosquito repellent has a slightly worse effect on the poisonous mosquitoes of the flower feet.

It's OK to put it in the room, if the area is large, it doesn't have much effect, but if you use it for a long time, I found that it doesn't have much effect, my family is now using this, child health care.
-
An electronic circuit is used to generate a kind of sound wave that mosquitoes do not hate to achieve the effect of repelling mosquitoes. This is theoretical, and I have not seen successful reports.
-
Electronic mosquito repellent is to send a certain frequency of ultrasonic signals to avoid mosquitoes approaching, although it is not harmful, but inefficient, it can be said to be a very chicken thing, and now the electronic mosquito repellent sold online is uneven, some of the bargains you buy may be a piece of decoration.

How does an electronic mosquito repellent work::
1.Using the principle of biomimicry, the horn is used to emit ultrasonic waves to create a noise environment that is difficult for mosquitoes to tolerate (such as ultrasonic waves emitted by natural enemies such as spiders, bats, dragonflies, etc.), and force mosquitoes to escape.
PS: This principle is like the sharp sound we hear when we use a knife to carve on glass, we are all unbearable!
2.Or imitate the courtship sound waves of male mosquitoes to make pregnant female mosquitoes "avoid suspicion".
PS: Female mosquitoes are blood-sucking because they need the blood of animals to reproduce their offspring. Male mosquitoes don't suck blood, only live on dew.
The sound waves used to repel mosquitoes are above 22000Hz, which is much higher than the hearing range of the human ear, so the human ear cannot hear it, and it will not affect the normal work, so as to achieve the effect of repelling insects and mosquitoes.
