Adjustment ring for automatic extinguishing of mosquito coils

Abstract

The invention discloses an adjusting ring for automatically extinguishing mosquito-repellent incense, which comprises a handle and a closed ring, the handle and the closed ring are connected together and are roughly in the shape of a P, and the size and shape of the cross-section of the closed ring is the same as that of the cross-section of the mosquito-repellent incense. The size and shape match, the handle and the closed ring are bent and wound from aluminum foil or tin foil, and the two ends of the aluminum foil or tin foil intersect at the junction of the handle and the closed ring; the width of the aluminum foil or tin foil is 5 ~10mm. The invention adopts a P-shaped adjustable ring structure, and the closed ring is tightly hooped at a certain position on the ignited strip or ring mosquito-repellent incense. When the mosquito-repellent incense burns to this ring, the temperature of the mosquito-repellent incense is reduced due to the rapid heat dissipation of the metal ring, and at the same time it is closed. The ring is tightly attached to the mosquito coil to isolate oxygen and suffocate the mosquito coil automatically, which can effectively save the mosquito coil and reduce the release of toxic substances; the handle of the P-shaped adjustable ring is easy to take, and the diameter of the ring can be adjusted, which is convenient Mobile operation.

Description

technical field [0001] The invention relates to a mosquito-repellent incense extinguishing adjusting device, in particular to an adjusting ring for automatically extinguishing the mosquito-repellent incense. Background technique [0002] In summer, people often light some ring or strip mosquito coils at home to repel mosquitoes, such as disc mosquito coils containing bimethrin. However, this type of mosquito coil is generally relatively long. Generally, the room area in the house is not very large, and there are partition walls. Several rooms cannot share a single mosquito coil, and it can only be burned after being ignited. First, for some rooms with a small area, it is obviously wasteful to burn one roll each time; second, after all, this type of mosquito coil is somewhat toxic, so use as little as possible. This requires selective control of the burning length of the mosquito coils depending on the size of the room, the climate characteristics of the north and the south,...

AI Technical Summary

Problems solved by technology

The existing technology uses manual extinguishing, or puts a semi-closed C-shaped iron ring upside down on the cross section of the mosquito coil to achieve it, but this kind of sealing is not very good, and it is easy to fail from the lower part, and the size of the original iron ring is relatively small , it is not easy to adjust the size of the hole, it will get stuck when moving back and forth, and it is not very convenient to use
