Description

Technical Field

[0001] The utility model relates to the technical field of moxa sticks, in particular to a moxa stick with an improved protective structure. Background Art

[0002] Moxa sticks are cylindrical long rolls made of moxa wrapped in cotton paper. Moxa sticks are mainly used for moxibustion. Moxibustion is one of the oldest medical techniques in China. It belongs to the external treatment of traditional Chinese medicine. It can warm the meridians and dispel cold, promote the flow of qi and blood, and expel cold and dampness. It is suitable for wind-cold dampness arthralgia, muscle soreness and numbness, joint and limb pain, cervical spondylosis and other symptoms. Among them, there is a moxa stick called thunder fire moxibustion, which is a moxa stick made by mixing traditional Chinese medicine powder with moxa. Therefore, thunder fire moxibustion moxa sticks are often larger in diameter and thicker, making them difficult to put into the moxibustion device when in use. Usually, a heat-insulating middle shell is set on the outside of the moxa stick, an ash-blocking sleeve is set on the front end of the moxa stick, and a hand-held tail shell is set on the rear end of the moxa stick. The heat-insulating middle shell plays a role of heat insulation, and the ash-blocking sleeve blocks the ashes produced by the burning of the moxa stick. The hand-held tail shell is set on the heat-insulating middle shell, and plays a role of secondary heat insulation when in use. After use, the hand-held tail shell is set on the front end of the moxa stick to automatically extinguish the moxa stick. In order to improve the use Convenience. The thermal insulation middle shell, ash barrier cover and hand-held tail shell are often discarded together with the moxa stick after use. In order to control costs and protect the environment, the thermal insulation middle shell, ash barrier cover and hand-held tail shell are usually made of paper materials. Therefore, the thermal insulation middle shell, the hand-held tail shell and the ash barrier cover are all tightly fitted. After long-term use, a fitting gap will be generated between the thermal insulation middle shell, the hand-held tail shell and the ash barrier cover, resulting in looseness between the thermal insulation middle shell, the hand-held tail shell and the ash barrier cover, which will cause the hand-held tail shell or the ash barrier cover to fall off, easily causing burns, with poor safety.

At least one silicone sheet is arranged on the outer surface of the insulating middle shell 2, and the silicone sheet is at least interference fit with the inner wall surface of the hand-held tail shell 3. When in use, remove the ash cover 4, light the moxa stick 1, and then put the ash cover 4 back, and perform moxibustion by holding the handheld tail shell 3; when the temperature needs to be adjusted, the distance between the moxa stick 1 and the skin is increased or shortened by moving the ash cover 4 forward and backward to achieve temperature adjustment; after use, remove the ash cover 4 and the handheld tail shell 3, and set the handheld tail shell 3 on the front of the heat-insulating middle shell 2, so that the handheld tail shell 3 and the heat-insulating middle shell 2 form a closed space, and the burning end of the moxa stick 1 is located in the closed space, so that the moxa stick 1 is extinguished, and finally remove the handheld tail shell 3 and put it back on the rear of the heat-insulating middle shell 2, and then put the ash cover 4 back. When in use, hold the handheld tail shell 3, and the handheld tail shell 3 increases the friction between the handheld tail shell 3 and the heat-insulating middle shell 2 through the silicone sheet to prevent the moxa stick 1 from falling due to its own weight, prevent burns, and improve reliability, stability and safety; reduce the processing accuracy of the diameter processing of the handheld tail shell 3 and the heat-insulating middle shell 2, and improve the production speed.

[0032] Specifically, the handheld tail shell 3 includes a first paper tube 31 which is hollow inside and cylindrically made of thin cardboard, a sealing cardboard 32 which is fixed on the upper part of the first paper tube 31 and closes the top surface of the first paper tube 31, and the bottom surface of the first paper tube 31 is open to form a first opening; the heat-insulating middle shell 2 includes a second paper tube 21 which is hollow inside and cylindrically made of thin cardboard, and the top and bottom surfaces are both open, and a flame-retardant layer 23 is provided on the inner wall surface of the heat-insulating middle shell 2; the dust-proof sleeve 4 includes a third paper tube 41 which is hollow inside and cylindrically made of thin cardboard, and the top surface of the third paper tube 41 is open to form a second opening, and a dust-proof net 42 is provided at the bottom of the third paper tube 41, and the dust-proof net 42 closes the bottom surface of the third paper tube 41.
