Description

Scald preventing moxibustion device

Technical Field

The invention relates to the technical field of medical and health-care instruments, in particular to an anti-scald moxibustion device.

Background

The use of moxa for acupuncture point fumigation has been widely noticed and widely popularized, and the effect of health care and beauty treatment is achieved by burning moxa for fumigation on acupuncture points and meridians on the surface layer of skin and by using the chemical action of medicine, infrared radiation and thermal stimulation generated in burning.

Firstly, the moxa therapy is a well-known safe therapy without side effects, the drug properties of the raw moxa and the cooked moxa are completely different, particularly, the moxa releases moxa smoke after burning, and a plurality of trace elements are invisible, and the combustion product of the moxa is detected, and the fact that the antioxidant substances can permeate through acupuncture points and permeate into the body through moxibustion heat to play a role is found, wherein the moxa smoke is called the soul of moxibustion, so that the moxa smoke plays a vital role in moxibustion.

Present moxibustion device, stifling in-process chinese mugwort cigarette heat of moxibustion is too concentrated and is caused local high temperature, and chinese mugwort cigarette is too concentrated release on by stifling skin, and then causes scald and unnecessary excessive treatment, and effectual carries out the homogeneous mixing to chinese mugwort cigarette temperature, is favorable to having improved the stifling treatment of moxa-moxibustion and has experienced.

In the prior art, as patent publication (publication) No.: CN201710638U discloses a moxibustion cup, which comprises a cup body with an opening at the bottom end, a cup cover and a moxa pot for placing moxa, wherein a plurality of first through holes are formed in the bottom surface and the peripheral wall surface of the moxa pot; the cup cover is provided with an air inlet hole, the air inlet hole is externally connected with an air pump through an air pipe, and the technical problems that smoke generated by burning moxa in the moxibustion cup in the prior art has no directivity and the smoke and heat are not concentrated enough are solved, but the cup cover has the defects that:

1. moxa smoke generated by the moxa is blown to the skin through the air pump, so that a large amount of moxa smoke is concentrated at the bottom of the moxa pot, the temperature at the bottom of the moxa pot is too high, and the skin is easily scalded;

2. when in use, the temperature of the moxa smoke cannot be controlled, and the moxa smoke just released is higher in temperature and is not suitable for directly acting on the skin;
