Abstract
Description
Technical Field
[0001] This utility model relates to the field of moxibustion technology, and more specifically, to a smoke-filtering moxibustion device. Background Technology
[0002] Moxibustion is an important component of Traditional Chinese Medicine (TCM) and one of the oldest medical methods in traditional medicine. Moxibustion, also known as moxibustion therapy, involves burning or warming moxa wool or other medicinal substances on acupoints on the body's surface. The heat from the moxa and the effects of the medicinal substances, transmitted through the meridians, warm and invigorate the flow of qi and blood, strengthen the body's resistance, and expel pathogenic factors, thus preventing and treating diseases.
[0003] However, existing moxibustion devices generate high temperatures and large amounts of smoke when the moxa sticks are burned. These devices do not have smoke filtering capabilities, which leads to smoke pollution of the surrounding environment. Furthermore, they cannot allow heat energy to fully penetrate the human body. Additionally, existing moxibustion devices are inconvenient to install and cannot ensure that the moxa sticks are centered, making it impossible to ensure that the moxa sticks are accurately aligned with the acupoints on the body surface during treatment, thus affecting the treatment effect. Utility Model Content
[0004] The technical problem this invention aims to solve is that existing moxibustion devices have poor smoke filtration effects and cannot guarantee precise positioning of the moxibustion column. To overcome the above-mentioned defects of the prior art, this invention provides a method that can suppress smoke emission at the body and top of the device through a first smoke filtration layer and a second smoke filtration layer, thereby improving the smoke filtration effect. At the same time, the positioning needle and positioning ring can facilitate the fixing and precise positioning of the moxibustion column, so that the moxibustion column is aligned with the acupoints on the body surface, ensuring the therapeutic effect.
[0005] To achieve the purpose of this utility model, the following technical solution is adopted: A smoke-filtering moxibustion device includes a base, an inner cylinder, a middle cylinder, an outer cylinder, a first smoke-filtering layer, a moxibustion fixing seat, a cylinder cover, and a second smoke-filtering layer. The middle cylinder is mounted on the base, and the inner cylinder is installed inside the middle cylinder. The outer cylinder is rotatably fitted onto the middle cylinder. The inner cylinder, middle cylinder, and outer cylinder are respectively provided with through holes in the inner cylinder, middle cylinder, and outer cylinder at intervals along the circumference. The through holes in the inner cylinder, middle cylinder, and outer cylinder are radially aligned and connected, and the size of the through holes can be adjusted by rotating the outer cylinder. The first smoke-filtering layer is disposed between the outer cylinder through hole of the outer cylinder and the middle cylinder through hole of the middle cylinder. The moxibustion fixing seat is installed inside the cylinder cover. The bottom of the moxibustion fixing seat is vertically provided with a positioning pin and a positioning ring. The positioning pin is located at the center of the positioning ring. The cylinder cover is fitted onto the middle cylinder, and the lower end face of the cylinder cover abuts against the upper end face of the outer cylinder, while allowing the moxibustion fixing seat to extend into the inner cylinder. The top of the cylinder cover is provided with an opening. The second smoke-filtering layer is disposed at the opening. This structure uses a first smoke filter layer to suppress and filter smoke emissions from the cylinder body and a second smoke filter layer to suppress and filter smoke emissions from the cylinder cover, thereby reducing the environmental pollution caused by smoke. It also allows more internal heat energy to penetrate into the human body. At the same time, the positioning pin facilitates the insertion of the moxibustion column, and the positioning ring limits and positions the moxibustion column, placing it in the center of the structure. This ensures that the moxibustion column can be aligned with the acupoints on the body surface during treatment, ultimately ensuring the therapeutic effect of moxibustion.

The cooperation of at least three locking rods and locking holes ensures the stability and flatness of the positioning ring connection, thereby preventing the positioning ring from tilting during installation. The bending also facilitates disassembly, cleaning, or replacement, improving assembly convenience.
[0008] Preferably, the outer peripheral wall of the positioning ring has several vent holes evenly distributed along the circumference. These vent holes reduce weight and material costs, while also facilitating the dissipation of smoke.
[0009] Preferably, the first fixing frame includes a first annular plate and a second annular plate; the first annular plate and the second annular plate are coaxially arranged and on the same plane, the through hole of the second annular plate is the positioning hole, and the first annular plate and the second annular plate are connected by four annular connecting plates. This structure facilitates the positioning of the fixing cylinder on the second annular plate.
[0010] Preferably, the second fixing frame includes a third annular plate and a cross plate; the cross plate and the third annular plate are on the same plane, the center of the cross plate is aligned with the center of the third annular plate, and the four ends of the cross plate are fixedly connected to the inner edge of the third annular plate. This structure facilitates the pressing of the cross plate against the fixing cylinder, thereby fixing and limiting the position of the fixing cylinder.

The cooperation of the boss and the limiting ring facilitates the further flat placement of the second smoke filter layer, and also facilitates the limitation and fixation of the second smoke filter layer.
[0012] Preferably, the base has a vertically penetrating channel; a positioning step is provided along the circumferential direction on the inner wall of the channel; a heat insulation plate is placed flat on the positioning step; several moxibustion flow holes are evenly distributed on the heat insulation plate; the upper end face of the heat insulation plate abuts against the lower end face of the middle cylinder, and the outer wall of the middle cylinder fits against the inner wall of the base, while the lower end face of the heat insulation plate abuts against the positioning step; the lower end face of the outer cylinder abuts against the upper end face of the base, and the outer wall of the outer cylinder connects with the outer wall of the base to form a complete cylinder. The heat insulation plate can prevent the moxibustion column from burning the human body surface during moxibustion, and also can block the ash from the moxibustion column.

[0022] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 1 to 4As shown, a smoke-filtering moxibustion device includes a base 1, an inner cylinder 2, a middle cylinder 3, an outer cylinder 4, a first smoke-filtering layer 5, a moxibustion fixing seat 6, a cylinder cover 7, and a second smoke-filtering layer 8. The middle cylinder 3 is mounted on the base 1, and the inner cylinder 2 is mounted inside the middle cylinder 3. The outer cylinder 4 is rotatably fitted onto the middle cylinder 3. The inner cylinder 2, middle cylinder 3, and outer cylinder 4 are respectively circumferentially spaced with inner cylinder through holes 20, middle cylinder through holes 30, and outer cylinder through holes 40, which are radially aligned and connected. The size of the air intake channel formed between the middle cylinder through holes 30 and the outer cylinder through holes 40 can be adjusted by rotating the outer cylinder 4, thereby better controlling the moxibustion temperature and allowing adjustment according to different human body temperature tolerances during moxibustion. The first smoke-filtering layer 5 is disposed between the outer cylinder through hole 40 of the outer cylinder 4 and the middle cylinder through hole 30 of the middle cylinder 3. In this embodiment, the first smoke-filtering layer 5 is smoke-filtering cotton, which plays a good role in filtering smoke. The moxibustion fixing seat 6 is installed inside the cylinder cover 7; the bottom of the moxibustion fixing seat 6 is vertically provided with a positioning pin 601 and a positioning ring 602; the positioning pin 601 is located at the center of the positioning ring 602; the cylinder cover 7 is fitted onto the middle cylinder 3, and the lower end face of the cylinder cover 7 abuts against the upper end face of the outer cylinder 4, while the moxibustion fixing seat 6 extends into the inner cylinder 2; the top of the cylinder cover 7 is provided with an opening 70; the second smoke filter layer 8 is provided at the opening 70. In this embodiment, the second smoke filter layer 8 is smoke filter cotton, which plays a good role in filtering smoke. This structure can suppress and filter smoke emission from the cylinder body through the first smoke filter layer 5 and the second smoke filter layer 8, which can suppress and filter smoke emission from the cylinder cover 7, thereby reducing the impact of smoke on environmental pollution and allowing more internal heat energy to penetrate into the human body. At the same time, the positioning pin 601 facilitates the insertion of the moxibustion column, and the positioning ring 602 limits and positions the moxibustion column, placing it in the center of the structure. This makes it easy to align the moxibustion column with the acupoints on the body surface during treatment, ultimately ensuring the therapeutic effect of moxibustion.
[0024] like Figures 1 to 4As shown, the moxibustion fixing base 6 includes a first fixing frame 61, a second fixing frame 62, and a fixing cylinder 63. The first fixing frame 61 is horizontally fixed inside the cylinder cover 7, and a positioning hole 610 is provided in the middle of the first fixing frame 61. A protruding edge 631 is provided on the outer peripheral wall of the top of the fixing cylinder 63. The fixing cylinder 63 is inserted into the positioning hole 610, and the protruding edge 631 abuts against the first fixing frame 61. The second fixing frame 62 is horizontally fixed inside the cylinder cover 7, and the second fixing frame 62 is located above the first fixing frame 61, and the first fixing frame 61 abuts against the protruding edge 631. A positioning pin 601 is vertically set in the center of the bottom plate 630 of the fixing cylinder 63, and the positioning pin 601 extends to the bottom of the bottom plate 630. A positioning ring 602 is installed below the bottom plate 630 of the fixing cylinder 63. The above-mentioned fixing method can ensure that the fixing cylinder 63 is accurately positioned, and also makes it easy for the positioning needle 601 to be positioned in the center of the cylinder, which improves the connection stability and ensures that the moxibustion column is aligned with the acupoints on the body surface.
[0025] like Figure 2 and Figure 4 As shown, the bottom surface of the fixed cylinder 63 has three vertically penetrating locking holes 632 evenly distributed circumferentially; the upper end surface of the positioning ring sleeve 602 has vertically oriented locking rods 603 evenly distributed circumferentially, corresponding to the locking holes 632; the upper end of the locking rod 603 extends into the locking hole 632 and is bent, so that the upper end of the bent locking rod 603 is limited on the bottom plate 630 of the fixed cylinder 63. The cooperation of at least three locking rods 603 and locking holes 632 ensures the stability and flatness of the positioning ring sleeve 602 connection, thereby preventing the positioning ring sleeve 602 from tilting during installation. The bending also facilitates disassembly, cleaning, or replacement, improving assembly convenience. Several vent holes 633 are evenly distributed circumferentially on the outer peripheral wall of the positioning ring sleeve 602. The vent holes 633 reduce weight and material costs, and also facilitate the dispersion of smoke.
[0026] like Figure 4 As shown, the first fixing frame 61 includes a first annular plate 611 and a second annular plate 612; the first annular plate 611 and the second annular plate 612 are coaxially arranged and on the same plane, the through hole of the second annular plate 612 is a positioning hole 610, and the first annular plate 611 and the second annular plate 612 are connected by four annular connecting plates 613. This structure facilitates the positioning of the fixing cylinder 63 on the second annular plate 612. The second fixing frame 62 includes a third annular plate 621 and a cross plate 622; the cross plate 622 and the third annular plate 621 are on the same plane, the center of the cross plate 622 is aligned with the center of the third annular plate 621, and the four ends of the cross plate 622 are fixedly connected to the inner edge of the third annular plate 621. This structure facilitates the pressing of the cross plate 622 against the fixing cylinder 63, fixing and positioning the fixing cylinder 63.
[0027] like Figure 2 As shown, the inner top wall of the cylinder cover 7 has a radially inwardly protruding boss 71 along the circumferential direction; the moxibustion fixing base 6 also includes a limiting ring 64; the lower end face of the limiting ring 64 abuts against the second fixing frame 62; the second smoke filter layer 8 is limited and fixed on the upper end face of the limiting ring 64 and the stepped surface 711 of the boss 71. The cooperation between the boss 71 and the limiting ring 64 facilitates the further flat placement of the second smoke filter layer 8, and also facilitates the limitation and fixation of the second smoke filter layer 8.
[0028] like Figure 2 and Figure 3 As shown, the base 1 has a vertically penetrating channel 10; a positioning step 11 is provided along the circumferential direction on the inner peripheral wall of the channel 10; a heat insulation plate 9 is placed flat on the positioning step 11; several moxibustion flow holes 91 are evenly distributed on the heat insulation plate 9; the upper end face of the heat insulation plate 9 abuts against the lower end face of the middle cylinder 3, and the outer peripheral wall of the middle cylinder 3 is in contact with the inner peripheral wall of the base 1, while the lower end face of the heat insulation plate 9 abuts against the positioning step 11; the lower end face of the outer cylinder 4 abuts against the upper end face of the base 1, and the outer peripheral wall of the outer cylinder 4 is connected to the outer peripheral wall of the base 1 to form a complete cylinder. The heat insulation plate 9 can prevent the moxibustion column from burning the human body surface during moxibustion, and can also block the ash from the moxibustion column.
[0029] This structure precisely positions the moxibustion column by vertically inserting its center into the positioning pin 601 and abutting the outer wall of the moxibustion column against the inner wall of the positioning ring 602. This ensures the moxibustion column is centered in the cylinder. The moxibustion column is then ignited, and the cylinder cap 7 is placed on the middle cylinder 3, placing the moxibustion column inside the inner cylinder 2. By rotating the outer cylinder 4, the size of the air intake channel formed between the outer cylinder through hole 40 on the outer cylinder 4 and the middle cylinder through hole 30 on the middle cylinder 3 is adjusted. An adhesive cloth is provided on the base 1, allowing the moxibustion column to be attached to the skin without requiring constant hand-holding, thus reducing the manual labor involved in moxibustion. The first smoke filter layer 5 and the second smoke filter layer 8 filter smoke from the cylinder body and top, reducing the environmental pollution caused by smoke. This allows more heat energy to penetrate into the body through the channel 10 on the base 1, ensuring the effectiveness of moxibustion.
[0030] The advantages of this invention are that the structure can suppress and filter smoke emission from the cylinder body through the first smoke filter layer 5 and the second smoke filter layer 8 can suppress and filter smoke emission from the cylinder cover 7, thereby reducing the impact of smoke on environmental pollution and allowing more internal heat energy to penetrate into the human body. At the same time, the positioning pin 601 facilitates the insertion of the moxibustion column, and the positioning ring 602 limits and positions the moxibustion column, placing it in the center of the structure. This makes it easy to align the moxibustion column with the acupoints on the body surface during treatment, ultimately ensuring the therapeutic effect of moxibustion.
