Description

Air supply structure of automatic moxibustion device with controllable smoke concentration Technical Field The invention relates to an automatic moxibustion device, in particular to a gas supply structure of an automatic moxibustion device with controllable smoke concentration. Background Along with the improvement of the living standard and the development of health care consciousness, the moxibustion is widely focused and promoted. Moxibustion, abbreviated as moxibustion or moxibustion, is a treatment method for preventing and treating diseases by stimulating acupoints or specific parts of human body with moxa stick, moxa column, generated moxa heat and moxa smoke and regulating physiological and biochemical functions of human body disorder by activating menstrual qi. In the moxa cone combustion process, a large amount of smog can be produced, and smell is strong and sharp, if the air flue leakproofness of moxa-moxibustion device is poor or do not set up flue gas purification recovery unit, can seriously influence moxa-moxibustion person's use experience and moxa-moxibustion effect, and polluted environment. In addition, the volume of current moxa-moxibustion device is too huge, is unfavorable for the person's of moxa-moxibustion to carry and use to restrict the popularization and application in a large number of moxa-moxibustion device. In order to reduce the volume of the moxibustion device, it is most important to simplify the structure of the air passage through which the smoke flows, and as long as the air passage is simplified, the volume of the moxibustion device is correspondingly reduced. At present, the prior art moxibustion device cannot well solve the above-mentioned problems, such as the moxibustion device described in patent applications 201710685628.3, 201710686394.4 and 201711348985.7, and although a plurality of raised propping portions are disposed on the side wall of the inner cavity of the combustion chamber, so that air in the combustion chamber circulates smoothly, and the moxa cone burns fully, and the propping portions are in a dot shape, a bar shape or a spiral shape. However, the processing procedures of the point-shaped propping part and the spiral propping part are complex, the manufacturing cost of enterprises is increased, in addition, the contact between the propping part and the moxa stick is point contact or line contact, and the strip-shaped propping part is arranged, so that the useless volume of the propping part is increased, the space for smoke circulation is reduced, and the combustion of the moxa stick is influenced. In addition, the air inlet device and the fan are arranged outside the moxibustion device, so that the moxibustion device is huge in size. Simultaneously, this moxibustion device's flue gas recovery unit sets up in moxibustion device's outside, has further increased the volume of device, carries inconvenient, is difficult to popularize and apply in a large number. The moxa-moxibustion device of patent application 201810046743.0 does not set up fume collecting device or fume purification device for in the direct entering air of flue gas, not only polluted environment, still influence moxa-moxibustion person's use experience. The automatic moxibustion device of integration that patent application 201910800799.5 was described, although arrange the main casing inside in air inlet unit for moxibustion device compact structure, but be used for placing the inner wall of the tubular combustion chamber of moxa cone at it and not be equipped with bellied portion of supporting, can lead to the inside circulation of air part of combustion chamber to be blocked, causes the insufficient phenomenon of moxa cone burning. In addition, this moxa-moxibustion device's flue gas recovery is also set up in the outside of moxa-moxibustion device, has increased the volume of device, and it is inconvenient to carry, uses loaded down with trivial details. The smokeless moxibustion apparatus described in patent application 201910574018.5, although provided with a smoke purification device, has an excessively long air passage and an excessively large volume, and can only be used indoors, thus restricting the popularization of the moxibustion apparatus. Therefore, the air passage structure of the moxibustion instrument is designed to be compact and simple in structure, good in sealing performance and simultaneously provided with the smoke purification device, and wide popularization and application of the moxibustion instrument are facilitated. In addition, the moxa-moxibustion device has the following problems that (1) the moxa smoke concentration in a fumigation chamber cannot be adjusted according to the bearing capacity of a moxa-moxibustion person so as to influence the moxa-moxibustion experience, (2) the required air outlets of the upper fumigation chamber with different volumes are different, when the number of the air outlets is too large, the processing and manufacturing c
