Why do mosquito coils have two plates together?In fact, don't you need to open something at all?After reading the long knowledge

Summer is more mosquito except for many people.

Especially when lying on the bed at night, they start to buzzish in your ears. As soon as you don't pay attention, you will leave a "red envelope" on you, making you more itchy and more itchy and more scratching.

Therefore, many people will order mosquito coils to drive mosquitoes in order to sleep peacefully.

So, the question is, do you know why mosquito coils have to be together?The answer is revealed below!

It turns out that there are several reasons for mosquito coils:

The first is to facilitate transportation.Because mosquito coils were invented in Japan a long time ago, two sets were together, which was relatively strong, and it was not easy to be destroyed during transportation.

The second is to reduce costs.Two sets can save half of the space together, the packaging is also saved, and the transportation fee is saved.

Finally, the production process is simple.During the production process, only one mosquito coil cutting machine is needed to make two pieces, which improves production efficiency.

Now, do you understand?
