Mosquito catcher of two rice engineers

A device with a simple structure, cheap and convenient, but it brings high efficiency for many livestock households.The mosquito-catching fan of Tran Van Lieu's "two-rice engineer" contributed to freeing poultry from insect attack and giving farmers great resources.

In 2007, after buying a good breed of cross-bred cows to raise for profit. Song forever but still can not recover the capital, because the herd is not large because of the strong attack of the mosquitoes. It is impossible to leave the sick, insomnia, skinny cows with their bones bitten by mosquitoes forever, so it is 'a hard thing to see' , the idea of ​​a suitable mosquito catcher for our cows he is very fragile and born.

Smoke 1 to 2 ounces of mosquitoes every night

Having a passion for physics, but because he had no conditions to study, so at the end of 12th grade, he was at home working in the fields. Therefore, the idea of ​​designing mosquito-catching fans is also an opportunity for him to fulfill his hobby. Before starting to build mosquito repellent for his herd, he tried to find similar types of mosquito repellent in the market, but none were effective and suitable. So after more than a month of thinking, tinkering with the properties of attraction, thrust and wind power, his mosquito-catching fan was born.

Mr. Lia's device for making mosquito-catching fans is quite simple. Just one electric fan, one 75W or 5W electric bulb (colored ball), 1m electric wire, 1m ² cardboard cover (or by steel sheet), 1m ² smooth mosquito net and 1 bottle of 502 glue, he made a catch fan mosquitoes consist of 3 parts that work according to the principle of attraction and repulsion. The design of the device is also quite simple, cut 2 cardboard and circled it into 2 round tubes, then use them on the front and back of the electric fan, put the colored light bulb into the round pipe in front of the fan (wind direction tube) ), round tube behind the fan connected to a smooth cloth.

When there is a lot of mosquitoes, strong winds, the user places the wind direction of the fan to catch the mosquito against the wind, connect the power and press the fan start button. Mosquitoes around will be mesmerized by the colored light bulb placed in the wind tunnel to fly by itself, the wind will push them into the rotating propeller, the rotation of the propeller sucks them into the inner round tube and pushes through the rear net , suffocated. In areas with a lot of mosquitoes such as pigsty and pigsty, this fan can catch every night from 1 to 2 mosquito.

Mr. Luo's mosquito repellent fan

The biggest advantage of this mosquito-catching fan is that it is easy to buy, easy to install, simple operation, easy to use, cheap (about 200 - 300 thousand VND / piece), low cost of electricity. . In addition, mosquitoes can be used as food for raising chickens, frogs and ornamental fish. Fans that catch mosquitoes are designed to be big or small depending on the case, so it is easy to apply widely in households from rural to urban areas, cafes, hospitals or wherever there are many mosquitoes, contributing to pushing back the epidemic. dengue fever, malaria and help people develop livestock better.

Big, fat pets, breeding people

After successfully tinkering with himself, Mr. Luo continued to set and instruct mechanic to manufacture more machines, then popularize it to people around the neighborhood. Because the machine is simple, compact, easy to use, efficient and cost less than 300,000 VND, the nearby households responded enthusiastically. The sound of the rumor is far away, soon, many farmers from Khanh Hoa, Dak Lak, Ca Mau and Ben Tre . come to Mr. Luo's house to order. Many people in the distance called him Mr. Luo to give technical instructions to design his own mosquito catcher, which he gave him enthusiastically.

Mr. Nguyen Van Lon - Chairman of Ninh Hoa District Farmers Association (Khanh Hoa) said: there have been many farmers from other localities have found Tran Van Luo to order or ask for instructions on how to build a catcher machine. coincide. Mr. Luo's mosquito catcher has won the prize in the 3rd contest of Khanh Hoa province's Technical Innovation Contest (2008-2009).

The number of mosquitoes caught by Mr. Luo is increasing in the market. Even some big cities like Ho Chi Minh City have installed mosquito catchers in Mr. Luo. Some livestock farms in Ho Chi Minh City's suburbs say: 'The farm often raises cows and pigs in quantities of up to hundreds, so mosquitoes are easy to grow and develop. From the day they used Mr. Luo's mosquito mosquito, the mosquitoes were reduced, so that cows could eat and sleep well. If popularizing the use of mosquito catchers in each household in rural areas, there will be a significant reduction in the amount of mosquitoes in the wild, stabilizing the ecological environment, effective breeding, contributing to limiting fever. cold and dengue fever . '.

From this success, Mr. Luo has improved the mosquito catcher into a rice trap machine to limit the use of pesticides. Basically, mosquito catchers and hoppers are the same, but the hopper is equipped with longer and larger straws and thrusters, with electric charging and safety switches. When using a machine that ties a tree branch, pull it close to the rice leaf to wake the hoppers. The results showed that it was very positive when the hoppers were sucked into the net bag quite a lot.

When asked about the registration of intellectual property for his products, Mr. Luo said he would proceed to file for submission to the provincial Department of Science and Technology to protect the rights of his products. Particularly, the design of mosquito catchers is quite simple, so those who live far away want to design their own products to serve their families, they can contact him directly for guidance.
