## Background
TECHNICAL FIELD
The present invention relates to a traditional Chinese medicine acupuncture therapy device, and particularly to a moxibustion device acting on a point of a human body.
BACKGROUND ART
Moxibustion is an important branch of acupuncture therapy and is one of important means in traditional Chinese medicine cure of disease. The acting ways of moxibustion include warm stimulation on the point during moxa combustion process, pharmacological action of volatile matters in moxa combustion and so on. Conventional moxibustion mostly comprises moxa column moxibustion and moxa stick moxibustion. However, whether moxa column moxibustion or moxa stick moxibustion, there is much smog released during moxibustion, which causes the patient and the doctor to difficultly withstand. At the same time, there is a risk that the patient may be scalded by the dispersed ash being burning during moxibustion. Furthermore, since the moxa column or moxa stick has not been packed by a container, moxa and thermal power is mostly wasted; temperature is not stable during moxibustion, the curative effect is affected, and the operation is not convenient, which have greatly limited the widespread applications of moxibustion.
Now, there are smokeless moxibustion product, moxibustion box and the like in the market. Most common smokeless moxibustion product is smokeless moxa stick, which is mixed mostly by carbonized moxa and wood carbon in certain proportions, the smoke is not strong during combustion, it is relatively convenient to use, however, since the material used is not moxa used by traditional moxibustion and naturally loses the moxibustion therapy effect offered by the traditional moxibustion, such smokeless moxibustion has not been the traditional moxibustion. Thousands of years ago, it was discussed and compared about the moxibustion in traditional Chinese medicine, it was concluded that moxa has the best moxibustion therapy effect compared to the other materials. Just as such, moxa was selected and fixed as moxibustion material in the development of thousands of years, there has been such “moxa” moxibustion. Accordingly, moxibustion can be considered as “moxa” moxibustion only in case that it selects moxa as the moxibustion material, and can not in other cases.
Whether the mixture mixed by carbonized moxa and wood carbon in certain proportions or pure carbonized moxa, has a varied property. Such moxa stick has a very high temperature of combustion, and it is easy to break and disperse during combustion, thereby causing the patient to scald, bubble, infect and so on. Although bubble moxibustion may be used in curing some special disease, such moxibustion therapy is disadvantageous to widely use, which is not easily to be accepted by people nowadays. Smokeless moxa stick differs from traditional moxa both in form and in nature, and basically, can not be called as “moxa” moxibustion; furthermore, the curative effect of traditional moxibustion is caused by a combination of various factors, including the pharmic property of moxa and all kinds of radiations produced during combustion, and is not a simple warm effect which now commercially available smokeless moxibustion basically only has so that it can not obtain true moxa moxibustion curative effect. Furthermore, the moxibustion temperature is still not stable, low or high, during moxibustion therapy using smokeless moxa stick, and is not easy to induce moxibustion transducing phenomena, thereby affecting curative effect.
The commercially available moxibustion box can control the combustion speed and temperature to some extent, but the controlling ranges is limited, also, the moxa column is not convenient to install, the moxibustion box is easy to overturn, and there is also the risk that the patient may be scalded by the dispersed ash and that fire occurs.

SPECIFIC MODE FOR CARRYING OUT THE INVENTION
In order to further set forth the technical means which the present invention takes for the intended purpose and efficiency achieved, the structures, features and efficiencies of the present invention are described in detail below taken in conjunction with the attached figures and the preferred embodiments.
Example 1
Example 1 of the present invention is shown in FIGS. 2, 3, 4 and 5. In this example, the magnetic moxibustion device includes a moxibustion canister body 6 and a moxibustion canister lid 1 which hermetically covers the upper end of the moxibustion canister body 6.
A moxa column mounting base for hanging moxa column 5 is detachably installed on the internal surface of the top wall of moxibustion canister lid 1 by a magnetic attraction structure, wherein, the magnetic attraction structure is comprised of a movable portion and a fixed portion, particularly a pair of magnetic sheets or one magnetic sheet and one ferromagnetic metal sheet, one of which acts as a fixed sheet 2 fixed on the top wall of the moxibustion canister lid 1, and the other acts as a movable sheet 13 fixed together with the moxa column mounting base. The fixed sheet 2 may be bonded on the top wall of the moxibustion canister lid 6 by a high-temperature resistant environmentally safe adhesive.
A magnet guiding needle 3 is fixed on the movable sheet 13 and extends perpendicularly to the surface of the movable sheet 13 toward the lower end of the moxibustion canister body 6. The magnet guiding needle 3 passed through the moxa column 5. The magnetic field of the magnetic attraction structure is guided out of the lower end of the moxibustion canister through the magnet guiding needle 3, and is applied to the human body moxibustion application position, so as to perform the moxibustion therapy and the magnet therapy at the same time.
The moxa column mounting base provided on the internal surface of the top wall of the moxibustion canister 1 consists of the movable sheet 13, the magnet guiding needle 3, and a moxa column fixing sleeve 12. The moxa column fixing sleeve 12 at one end is fixed together with the movable sheet 13. The magnet guiding needle 3 is located within the moxa column fixing sleeve 12. The moxa column fixing sleeve 12 has an internal diameter slightly less than the external diameter of the moxa column 5, so that the moxa column 5 is inserted in and fixed to the moxa column fixing sleeve 12 via one end, and at the same time, the magnet guiding needle 3 is inserted in the moxa column 5.
The magnet guiding needle 3 axially extends through the moxa column 5 from the top down. Ash produced by the combustion of the moxa column 5 is collected around the magnet guiding needle 3 on the basis of the side of the magnet guiding needle 3 encircled by the moxa column 5, thereby avoiding its falling and scalding the patient.
In the moxa column fixing sleeve 12 is provided with a moxa column heat-insulated structure for obstructing heat during the combustion of the moxa column 5 from transferring to the top wall of the moxibustion canister lid 1; the heat-insulated structure is made of cylindrical wood block 4.
On a side wall of the moxa column fixing sleeve 12 is further provided with a through hole for discharging high-temperature gas produced within the moxa column fixing sleeve 12 during the combustion of the moxa column 5. A gap is formed between the endface of one end where the moxa column 5 is inserted into the moxa column fixing sleeve 12 and the lower endface of the moxa column heat-insulated structure. The gap communicates with the through hole, both of them facilitating the combustion of the moxa column 5.
A side wall of the moxibustion canister 6 is provided with several air inlets 7 in peripheral and uniform distribution close to the lower end of the moxibustion canister, and is provided with several air outlets 11 in peripheral and uniform distribution close to the upper end thereof; during the combustion of the moxa column 5, air enters from the gas inlets 7 and exits from the gas outlets 11.
Both the moxibustion canister body 6 and the moxibustion canister lid 1 are of a cylindrical shape. The gas inlets 7 and the gas outlets 11 include a number of, preferably 2-6, inlets and outlets peripherally uniformly distributed on the moxibustion canister body 6, respectively.
The moxibustion canister lid 1 is inserted in the upper end of the moxibustion canister body 6 via a section of canister wall of itself thereof. The gas outlets 11 are positioned at the location where the moxibustion canister body 6 overlaps with the moxibustion canister lid 1, and radially extend through both the moxibustion canister body 6 and the moxibustion canister lid 1, so that the moxibustion canister lid 1 can be rotated relative to the moxibustion canister body 6, thereby adjusting the opening size of the gas outlets 11 and controlling air flow within the moxibustion canister body 6, and therefore controlling the combustion speed of the moxa column 5 for the purpose of adjusting the moxibustion temperature.
At the lower end of the moxibustion canister body 6 is provided a ring-shaped moxibustion seat 9 with an opening in the middle. On the lateral surface of the moxibustion seat 9 facing the moxibustion canister body 6 is provided a screen partition 10 for covering the opening in the middle, in which a number of through holes are thickly distributed. The moxibustion therapy generated during the combustion of the moxa column 5 can act on the moxibustion site of the human body through the through holes in the screen partition. The screen partition 10 is positioned on the upper surface of the moxibustion seat 9, which can effectively separate the lower surface of the partition 10 from the human skin so as to avoid burn or scald. In addition, the through holes in the screen partition 10 may not have an excessive hole size so that ash produced by the combustion of the moxa column 5 is prevented from falling onto the human skin by the through holes, which may cause burn or scald.
On each of the inner surfaces of the moxibustion canister body 6, the moxibustion canister lid 1, the moxibustion seat 9, and the screen partition 10, is provided with a heat reflecting film having flame retardant characteristic. In this way, not only the loss of heat of the magnetic moxibustion device is reduced and the moxibustion therapy effect is improved, but also the usage safety of the magnetic moxibustion device is enhanced.
In order to facilitate the usage of the magnetic moxibustion device, a medical adhesive tape 8 is arranged on the magnetic moxibustion device, and is sleeved on the moxibustion canister body 6 via a through hole thereon. The ring-shaped moxibustion seat 9 has a flange matching with the medical adhesive tape 8 and radially projecting from the external surface of the moxibustion canister body 6. The medical adhesive tape 8 fixes the whole magnetic moxibustion device to the moxibustion site of the patient by pressing against the upper surface of the flange.
Instead of providing the moxa column fixing sleeve 12, the above moxa column mounting base may only consists of the movable sheet 13 and the magnet guiding needle 3. In this case, the moxa column 5 is inserted in the magnet guiding needle 3, and its position then is determined by changing the insertion depth of the magnet guiding needle 3.
Each of the moxibustion canister body 6, the moxibustion canister lid 1, and the moxa column fixing sleeve 12 is made of relative hard paperboard.
In using the above magnetic moxibustion device, first, the moxa column 5 is fixed on the moxa column fixing sleeve 12, and after firing the moxa column 5, the moxibustion canister lid 1 hermetically covers the moxibustion canister body 6, then, the magnetic moxibustion device is fixed on the moxibustion site of the human body by means of the medical adhesive tape 8, and the moxibustion canister body 6 is rotated relative to the moxibustion canister lid 1 so that the moxa column 5 is adjusted to a proper combustion speed and the moxibustion is carried out.
As shown in FIG. 6, during the moxibustion, the magnetic moxibustion device according to the present invention, in addition to the moxibustion therapy action produced during combustion of the moxa column 5, carries out magnetic therapy on the moxibustion site of the human body via the magnetic field, thereby producing the combination effect of the moxibustion therapy and the magnetism therapy.
Example 2
Example 2 is shown in FIG. 7, which differs from example 1 in that the moxa column heat-insulated structure in the moxa column fixing sleeve 12 is formed by a thermal baffle. In order to ensure heat insulation effect of the thermal baffle, one to three layers of thermal baffles may be provided in the moxa column fixing sleeve 12, so that one to three layers of heat-insulated spaces are divided above the upper endface of the moxa column 5, which cooperates with the thermal baffles so as to better isolate the combustion temperature of the moxa column 5.
Example 3
Example 3 is shown in FIG. 8, which differs from example 1 in that in this example, the portion of air outlets 11 extending through the moxibustion canister lid 1 is shaped as groove. With this groove, it is also achieved that the opening size of the air outlets 11 can be adjusted.
Example 4
Example 4 is shown in FIG. 9, which differs from example 1 in that in this example, the moxibustion canister lid 1 hermetically covers the upper end of the moxibustion canister body 6 in a sleeving way. The air outlets 11 are positioned at the location where the moxibustion canister body 6 overlaps with the moxibustion canister lid 1. Similarly, by rotating the moxibustion canister lid 1 relative to the moxibustion canister body 6, the opening size of the air outlets 11 can be adjusted.
Example 5
Example 5 is shown in FIG. 10, which differs from example 1 in that in this example, both the movable portion of the magnetic attraction structure and the magnet guiding needle 3 are made of ferromagnetic material, and the movable portion is directly formed of a metal ring manufactured by bending the upper end of the magnet guiding needle 3. The metal ring positioned on the upper end of the magnet guiding needle 3 can facilitate the installation thereof on the fixed portion.
Example 6
Example 6 is shown in FIG. 11, which differs from example 1 in that in this example, the screen partition 10 has a gap from the lower end of the moxibustion canister body 6 to ensure that it can not be in contact with the skin at the moxibustion site of the human body. Thus, the safety of the magnetic moxibustion device is enhanced by raising the screen partition 10 in height.
Example 7
Example 7 is shown in FIG. 12, which differs from example 1 in that in this example, a clamp spring 14 is provided within the moxibustion canister lid 1. A seat ring on the upper portion of the clamp spring 14 is bonded on the top wall of the moxibustion canister lid 1 and an elastic claw on the lower portion clamps the moxa column fixing sleeve 12, thereby preventing the moxa column mounting base from waggling or accidently disengaging due to the unsteady attraction between the movable portion and the fixed portion.
Example 8
Example 8 is shown in FIGS. 13 and 14, which differs from example 1 in that in this example, a snap ring 15 is provided within the moxibustion canister lid 1. The snap ring 15 in the middle is provided with a center bore matching with the moxa column fixing sleeve 12. A leg on a side of the snap ring 15 is bonded to the side wall or top wall of the moxibustion canister lid 1. The center bore in the middle of the snap ring 15 clamps the moxa column fixing sleeve 12, thereby preventing the moxa column mounting base from waggling or accidently disengaging due to the unsteady attraction between the movable portion and the fixed portion.
Example 9
Example 9 is shown in FIG. 15, which differs from example 8 in that in this example, the moxa column mounting base is comprised of a fixed sheet 2 made of a magnetic sheet and a moxa column fixing sleeve 12. The upper end of the moxa column mounting base is adhesively fixed to the top wall of the moxibustion canister via the fixed sheet 1.
The upper end of the moxa column fixing sleeve 12 is adhesively fixed to the fixed sheet 2, so as to firmly install the moxa column 5.
A magnet guiding needle 3 is provided within the moxa column mounting base. The magnet guiding needle 3 passes through the moxa column 5 with its depth of at least one third of the full-length of the moxa column; the top end of the magnet guiding needle 3 has a ferromagnetic sheet for attracting the magnet guiding needle 3 onto the fixed sheet 2. The ferromagnetic sheet and the magnet guiding needle 3 are formed integrally and may in whole be made of ferromagnetic material, thereby having better magnetic conductivity.
A snap ring 15 is provided within the moxibustion canister lid 1. The snap ring 15 in the middle is provided with a center bore matching with the moxa column fixing sleeve 12, around which are uniformly distributed breathing holes, a side of the snap ring 15 is bonded to a side wall of the moxibustion canister lid 1. The center bore in the middle of the snap ring 15 clamps the moxa column fixing sleeve 12, thereby preventing the moxa column mounting base from waggling or accidently disengaging in replacing the moxa column 5.
