when the moxa cone burns, a conical combustion surface is naturally formed, and the furnace cushion 2 is a claw-shaped furnace cushion 17 or a conical net-shaped furnace cushion 18 or a protruding part 16 arranged on the cavity wall at the bottom of the inner cavity of the combustion chamber 1, so that the furnace cushion 2 can prop up the moxa cone to enable a space (or called a combustion space) for air circulation to exist between the lower part of the moxa cone and the moxa cone. The furnace cushion 2 gradually contracts inwards from top to bottom to form a conical cylindrical structure, and the conical combustion surface is very properly matched with a conical combustion surface formed by moxa cone combustion.

And because the bottom cavity wall of the combustion chamber 1 extends inwards and downwards to be folded, the bottom cavity wall of the combustion chamber 1 is provided with an air outlet 9, and the air outlet 9 enables the inner cavity 4 of the combustion chamber to be communicated with the outside of the combustion chamber 1. The bottom cavity wall of the combustion chamber 1 extends downwards inwards to be folded, the circulation space of constraint air is not very proper to match the conical combustion surface formed by the combustion of the moxa cone 11, further control air enables air to flow through the space formed between the conical combustion surface and the furnace cushion 2 where the moxa cone 11 is burnt, air is circulated at the bottom of the moxa cone 11 which needs to be burnt, further air is prevented from flowing to the fumigation chamber 3 in a nearby way without effective combustion, further air flowing to the fumigation chamber 3 is air after the moxa cone 11 is effectively burnt, therefore, the concentration of smoke is further improved, the use efficiency of the air is further improved, the heat of unit air burnt by the moxa cone 11 is further improved, the fumigation effect of moxa moxibustion is improved, air is saved, the combustion is fully odorless, the concentration and the heat utilization rate are high, and the fumigation treatment effect is good.

In addition, the moxibustion device further comprises a combustion chamber outer sleeve 13 which is arranged outside the combustion chamber 1 and generates smoke heat after the combustion of the moxa cone 11.

The working principle and innovation points of the invention are as follows:

1. when igniting moxa cone 11 bottom, moxa cone 11 begins the burning from the bottom, and in the moxa cone 11 combustion process, the moxa ash of burning drops stove pad 2, the elastic component 7 forces the unburned part of moxa cone 11 to push up on stove pad 2 all the time, and elastic component 7 and stove pad 2 combined action make the moxa cone hug closely the burning 1 room bottom stove pad 2 all the time and burn, because the more the air is concentrated near combustion 1 bottom the moxa cone 11, the faster the burning, the elastic component 7 and stove pad 2 combined action makes moxa cone 11 combustion end in combustion 1 bottom and from skin distance constantly all the time to make the air that circulates must pass through the moxa cone combustion face, reach the purpose of make full use of saving air.

2. The bottom cavity wall of the combustion chamber 1 extends downwards inwards to be folded, the air circulation space is restrained to be very proper to match with the conical combustion surface formed by the combustion of the moxa cone 11, air is further controlled to enable air to flow through the space formed between the conical combustion surface and the furnace cushion 2 where the moxa cone 11 is combusted, air is circulated only at the bottom of the moxa cone 11 needing to be combusted, the air is further prevented from flowing to the fumigation chamber 3 in a nearby way without effective combustion, the air flowing to the fumigation chamber 3 is further air after the moxa cone is effectively combusted, so that the concentration of smoke is further improved, the use efficiency of the air is further improved, the heat of unit air combusted by the moxa cone is further improved, the fumigation effect of moxa moxibustion is improved, the air is saved, the combustion is full, no peculiar smell is generated, the smoke concentration and the heat utilization rate are high, and the fumigation treatment effect is good.

The stove pad 2 at the bottom of the combustion chamber is a claw-shaped stove pad 17 or a plurality of protruding parts 16 or conical column-shaped net stove pads 18 uniformly fixed on the periphery of the cavity wall at the bottom of the combustion chamber 1, and because the type of structure is of a hollow structure and is designed to shrink inwards from top to bottom, the stove pad can play a role in blocking air and limiting air circulation, force air to cling to the combustion surface of the moxa column 11 to circulate, and match with the conical moxa column combustion surface naturally formed in the combustion process of the moxa column 11 so as to enable the moxa column to burn more fully, and the flue gas concentration and the heat utilization rate are high.

4. The raised abutment 6 forces the moxa cone 11 to be unable to contact the inner side wall of the combustion chamber 1 in a large area, so that air can flow through the side surface of the entire moxa cone 11 only along the limited and controllable space formed between the inner side cavity wall of the combustion chamber 1 and the moxa cone 11. The furnace cushion 2 at the bottom of the combustion chamber 1, the elastic piece 7 and the raised supporting part 6 on the inner side wall of the combustion chamber 1 are combined to enable circulated air to pass through the combustion surface of the moxa cone 11, so that the purpose of fully utilizing the air is achieved, the moxa cone 11 is always attached to the furnace cushion 2 for combustion, and the more the moxa cone 11 is attached to the bottom of the combustion chamber 1, the faster the air is combusted, so that the taper-shaped combustion end formed in the combustion process of the combustion end of the moxa cone 11 is controlled to be always matched with the shape of the furnace cushion 2, and the effect of the elastic piece 7 enables the combustion end of the moxa cone 11 to be always at the bottom of the combustion chamber 11 and the distance from the skin is always unchanged.

5. According to the invention, the air-driven flow guiding mechanism 21 is arranged to supply oxygen and ventilate the sealed combustion chamber 1 and the sealed fumigation chamber 3 in the moxibustion process and discharge the flue gas fumigated by the skin, so that the air flow flows according to the specified direction, the specified flow speed and the specified flow rate, and the purpose of controllable flue gas is achieved, thereby increasing the curative effect of the fumigation of the moxibustion. The air driving and guiding mechanism 21 such as a fan or a vacuum pump can control the burning speed and the temperature of the moxa cone by adjusting and controlling the air supply amount and the air supply speed, so that the air flows in a specified direction to increase the moxibustion curative effect.

6. The design of the buffer chamber 5 and the buffer chamber 5 which are arranged between the combustion chamber 1 and the fumigation chamber 3 and are two-layer chambers, namely the design of the buffer inner chamber and the buffer outer chamber which are arranged inside and outside respectively, effectively solves the problems that the local temperature is too high due to the fact that the flue gas heat is too concentrated in the fumigation process of moxibustion, the flue gas is released on the fumigated skin too intensively, scalding and unnecessary excessive treatment are caused, the air temperature is uniformly mixed effectively, the fumigation treatment experience of the moxibustion is improved, and the moxibustion fumigation is carried out under a proper temperature and a proper flue gas concentration.

7. The invention effectively solves the problems that smoke generated by moxa sticks or moxa sticks in the combustion process can not be effectively controlled and seriously pollutes the environment by arranging the smoke recovery device, so that both doctors and patients can not be damaged to different degrees in the treatment process, and further solves the problem that moxibustion can not be widely popularized from ancient times to date.
