Many people worry that the smell of backflow incense is harmful to human body. When using reflux fragrance, we should avoid using bad perfume made of chemical essence. This kind of inferior perfume has bright color and pungent smell, which can be harmful to human body. As long as the raw materials used are safe, there is no problem in producing qualified reflux incense.
The reason why the backflow incense can flow downwards is mainly related to the structure of the backflow incense burner. Reflux incense has a hole, which is precisely aligned with the hole of reflow incense. After burning, it will be isolated from the air, and the burning smoke will flow out of the small holes of the incense column after cooling in the incense column, thus causing backflow. Most incense burners are black or dark gray-brown, which is in sharp contrast to the smoke produced when incense burns.
Reflux incense burner should pay attention to:
1, don't choose to use inferior reflow incense.
2. Don't burn too much incense each time when lighting the reflow incense, 2 sticks 1 is enough.
3. When burning incense, it is best to open a window in the house to keep indoor air circulation.
4, incense should be placed in a safe place without flammable materials.
5. Don't smoke incense in the bedroom for a long time.
