[0002] Moxibustion therapy is one of the oldest medical techniques in China and a method of external treatment in Traditional Chinese Medicine. It uses moxa or other drugs to burn and warm the acupuncture points on the body surface, and uses the heat of the moxibustion fire and the effects of the drugs to conduct through the meridians to warm the Qi and blood, strengthen the body and eliminate evil, and achieve the purpose of preventing and treating diseases.

[0003] Moxibustion therapy is to burn moxa sticks to obtain high-temperature smoke containing medicinal ingredients to burn the patient's skin to achieve the purpose of treatment. The upper end surface of the existing moxa stick is flat, and it takes a long time to ignite. In addition, the existing moxa stick can generally only be used in a fixed position and is not convenient to carry. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a moxa stick to overcome the deficiencies in the above-mentioned prior art.

[0006] The moxa stick has an air hole inside, the lower end of the air hole penetrates the lower end surface of the moxa stick, and the upper end surface of the moxa stick has a plurality of intersecting grooves, and the air hole and the groove are not connected.

[0007] The beneficial effect of the present invention is that when igniting, the intersection of the grooves is ignited, which is conducive to airflow circulation and can accelerate the ignition of the moxa stick so that the moxa stick has sufficient combustion power in a short time to connect the air holes for rapid burning.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the bottom surface of the groove is an arc-shaped surface.

[0010] The above further beneficial effects are: it has a certain fire gathering effect, which is more conducive to allowing the moxa stick to have sufficient burning power in a short time, and can further shorten the distance between the pores and the grooves.

[0011] Based on the above technical solution, the present invention also provides a portable moxibustion, a moxibustion instrument and a moxa stick, wherein the moxa stick is placed in the moxibustion instrument.

[0012] The above method has the further beneficial effect that the moxa stick is combined with the moxibustion apparatus, so that moxibustion can be performed anytime and anywhere, and the method is convenient to carry.

[0013] Furthermore, the moxibustion device includes: a housing, an upper cover, a bottom cover, a lighter, and a positioning seat.

Each branch of the traction wire passes through a wire passing hole and is connected to the free end of a metal sheet; a lighter wire is arranged on each metal sheet, and the lighter wire is connected to the power source through a wire.

[0016] The beneficial effect of the above is: By winding the traction wire with the winding device, the free end of the metal sheet can be pulled to bend towards the fixing column to form an arc structure. And by unwinding the traction wire with the winding device, the metal sheet can be restored to its original horizontal state; multiple metal sheets are formed into an arc structure adapted to the groove and are close to the groove of the moxa stick.

[0022] The beneficial effect of the above is as follows: When the first telescopic cylinder contracts, the structure formed by the metal sheet, the ignition wire and the fixing column can be close to the moxa stick, and when the first telescopic cylinder extends, the structure formed by the metal sheet, the ignition wire and the fixing column can be far away from the moxa stick;

[0023] When the second telescopic cylinder contracts, the third telescopic cylinder will synchronously contract under the action of the second telescopic cylinder and the ash collecting plate, so that the length direction of the moxa stick extending out of the third telescopic cylinder changes;

[0025] In addition, the introduction of the first telescopic cylinder, the second telescopic cylinder and the third telescopic cylinder enables the portable moxibustion device to change its size to adapt to moxa cones of different lengths.

[0026] Further, an ash collecting groove is provided on the ash collecting plate around the third telescopic cylinder.

[0027] The beneficial effect of the above is as follows: The ash collecting groove can collect the ash removed from the moxa stick and prevent the ash from scattering.
