Description

Moxa cigarette collection petticoat pipe

Technical Field

The utility model relates to a device for collecting smoke, in particular to a moxa smoke collecting hood.

Background

Moxibustion is a physiotherapy and health care method selected by many people.

At present, the biggest problem when the handheld traditional moxa stick is used for moxibustion is that a large amount of moxa smoke is generated when moxa is burnt, and the moxa smoke can be dispersed everywhere along with the burning of the moxa stick and the movement of the handheld moxa stick for moxibustion, so that air pollution is caused. Generally, a smoke collecting hood is used to collect moxa smoke, referring to fig. 1, a conventional moxa smoke collecting hood is generally composed of a hood 01 and a smoke exhaust 04/smoke guide tube on the side of the hood 01. The moxa smoke generated by the combustion part of the moxa stick 02 is sucked out by the negative pressure of the smoke exhaust pipe 04/the smoke guide pipe on the side surface of the cover 01, so as to achieve the purpose of smoke exhaust. Such hoods are characterized by simplicity, but also have drawbacks. The disadvantage is that since the smoke exhaust pipe 04/smoke guide pipe is at the side of the cover 01, when the smoke in the cover 01 enters the smoke exhaust pipe 04 under the action of negative pressure, the smoke flow speed near the smoke exhaust pipe 04 is the fastest, and the smoke flow at the other side of the cover 01 is the slowest, and is not even easily influenced by the negative pressure (the influence depends on the size of the cover 01 and the size of the negative pressure). As a result, moxa sticks 02 burn unevenly, the part close to the smoke exhaust pipe 04 burns quickly, the part far away from the smoke exhaust pipe 04 burns slowly, and the moxa sticks 02 form inclined combustion bodies due to uneven combustion, so that the heat emitted by the moxa sticks is different, and the local effect of moxibustion is different; meanwhile, moxa smoke in the smoke collecting hood cannot be completely sucked out of the smoke exhausting hood, so that the moxa smoke overflows. And the suction force is increased to cause the moxa roll 02 to burn too fast to meet the requirements of moxibustion physiotherapy effect.
