Description

Technical Field

[0001] This utility model relates to the field of physiotherapy device technology, specifically a positioning anti-scalding adjustable multifunctional moxibustion device. Background Technology

[0002] Moxibustion therapy relies on the warming effect and pharmacological volatiles produced by the burning of moxa wool, moxa cones, or moxa sticks to act on acupoints on the human body. It is a highly popular therapy method in traditional Chinese medicine clinical practice and home health maintenance. With the continuous increase in public demand for health and wellness, portable single-person moxibustion cylinders that are hand-held and can be fixed with adhesive tape are gradually replacing traditional handheld moxibustion devices, significantly lowering the barrier to moxibustion operation and allowing for long-term, targeted moxibustion without assistance. Currently available portable moxibustion cylinders generally feature a cylindrical outer shell with a breathable mesh at the bottom for storing the moxa material. They are equipped with adhesive patches, elastic straps, and other accessories for surface positioning and are widely used in community physiotherapy centers, daily home health maintenance, post-operative localized heat rehabilitation, and joint care for middle-aged and elderly individuals.

[0003] Existing adhesive portable moxibustion tubes have a fixed fixing structure that cannot flexibly adjust the pressure between the breathable mesh at the bottom of the moxibustion tube and the skin. The fixing structure and the moxibustion tube are integrally molded and cannot be separated. After installation, the distance between the moxibustion tube and the skin remains fixed, and the user cannot adjust the tightness of the fit according to their own skin's heat tolerance or the duration of moxibustion. Once the fit is fixed, the intensity of heat transfer from the burning moxa inside the moxibustion tube to the skin cannot be adjusted. If the fit is too tight, it can cause continuous high-temperature stimulation to the local skin. If the fit is too loose, a large amount of smoke will escape from the gap between the bottom of the moxibustion tube and the skin, reducing the utilization rate of the medicinal efficacy. The existing fixing structure does not have an integrated adjustment function that simultaneously adjusts the tightness of the fit, controls the temperature, and controls the escape of smoke. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning, anti-scalding, adjustable, multifunctional moxibustion device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A positioning, anti-scalding, adjustable, multi-functional moxibustion device, including

[0007] The moxibustion tube has an openable and closable cap at the top and a breathable mesh at the bottom.

[0008] A positioning and adjustment component, detachably sleeved on the outer wall of the moxibustion cylinder, includes:

[0009] An elastic collar is fitted onto the outer wall of the moxibustion tube;

[0010] Several flexible connecting arms are distributed at intervals along the circumference of the elastic collar. One end of each flexible connecting arm is fixed to the elastic collar, and the other end is fixed with a suction cup that can be adsorbed and positioned on the surface of human skin.

[0011] The flexible connecting arm acts as the hypotenuse of the triangle formed by the moxibustion cylinder axis, human skin, and the flexible connecting arm. When the elastic collar is at different positions on the outer wall of the moxibustion cylinder, the angle between the flexible connecting arm and the moxibustion cylinder axis changes. When the suction cup is adsorbed onto the human skin surface and the flexible connecting arm is in a tensioned state, the magnitude of the axial pressing force applied by the flexible connecting arm to the moxibustion cylinder on the side facing the human skin changes accordingly, and the angle between the flexible connecting arm and the moxibustion cylinder axis is in the range of 30°~60°.

[0012] Preferably, when the elastic collar is at the end of the moxibustion cylinder near the cylinder cap, the angle between the flexible connecting arm and the axis of the moxibustion cylinder is the smallest; when the elastic collar is at the end of the moxibustion cylinder near the breathable mesh, the angle between the flexible connecting arm and the axis of the moxibustion cylinder is the largest.

[0013] Preferably, the flexible connecting arm is a strip of rubber, and each of the flexible connecting arms is equally spaced on the circumferential side of the elastic collar. In the non-adhesive state, the connection end of the flexible connecting arm and the circumferential side of the elastic collar is set at an acute angle of 40°~50°, and the connection end of the flexible connecting arm on the circumferential side of the elastic collar points obliquely downward toward the plane where the breathable mesh is located.

[0014] Preferably, the suction cup is a bowl-shaped disc, and the end of the flexible connecting arm away from the elastic collar is connected to the outer wall of the suction cup and coincides with the central axis of the suction cup. The flexible connecting arm points obliquely upward from its connection end with the suction cup towards the elastic collar, and the flexible connecting arm is set at an acute angle of 40° to 50° with the axis of the suction cup.

[0015] Preferably, in the non-adsorbed state, the inner diameter of the elastic collar is smaller than the outer diameter of the moxibustion tube, and the inner wall surface of the elastic collar is provided with an annular protrusion extending circumferentially therein, the cross-section of the annular protrusion being semi-circular or trapezoidal.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The elastic collar of this utility model can change the angle between the flexible connecting arm and the axis of the cylinder by sliding up and down along the outer wall of the moxibustion cylinder. The change of the angle adjusts the axial clamping force synchronously. Users can freely adjust the tightness of the fit between the bottom ventilation mesh of the moxibustion cylinder and the skin according to their own temperature tolerance. When the elastic collar is close to the ventilation mesh, the moxibustion cylinder fits the skin more tightly, reducing the loss of smoke from the bottom gap. When the elastic collar is close to the cylinder cover, a small gap is maintained between the moxibustion cylinder and the skin, the heat conduction intensity is weakened, the body surface warmth is more gentle, and the discomfort of high temperature stimulation is reduced.

[0018] 2. The elastic collar of this utility model has multiple flexible connecting arms and suction cups evenly distributed on its outer circumference, which can simultaneously adsorb human skin at multiple points. The circumferential tension is evenly distributed around the moxibustion tube. When turning over or making slight movements of the limbs during moxibustion, the moxibustion tube is less likely to slip or shift, resulting in higher precision in targeted moxibustion. If a single suction cup accidentally detaches, the remaining suction cups can still maintain the basic positioning of the moxibustion tube and will not fall off as a whole, thus improving the stability of use.

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example

[0030] like Figures 1-7 As shown, a positioning, anti-scalding, adjustable multi-functional moxibustion device includes a moxibustion cylinder 1, with an openable and closable cylinder cover 2 at the top and a breathable mesh 3 at the bottom.

[0031] The moxibustion cylinder 1 is a hollow cylindrical body. Multiple sets of rhomboid ventilation holes and circular heat dissipation holes are staggered along the axial and circumferential directions on the side wall of the cylinder. The diameter of the rhomboid holes is larger than that of the circular heat dissipation holes. The rhomboid holes are mainly used for the outward flow of smoke generated by the burning moxa inside the cylinder. The circular heat dissipation holes are distributed at the upper and lower ends of the cylinder body, which mainly guides the heat accumulated at both ends of the cylinder wall and reduces the surface temperature of the outer shell of the cylinder body. When the user holds and touches the cylinder body, they are less likely to be burned by high temperature, thus achieving a basic anti-scalding effect.

[0032] The outer wall of the top opening of the moxibustion cylinder 1 is provided with an external thread, which matches and screws into the inner thread of the inner wall of the cylinder cover 2, so that the cylinder cover 2 can be opened and closed and sealed. A circular lifting protrusion is provided in the center of the top surface of the cylinder cover 2, which makes it easy to unscrew and close the cylinder cover 2. The metal moxa stick needle is fixed vertically downward inside the cylinder cover 2. The length of the needle is two-thirds of the height of the internal cavity of the moxibustion cylinder 1. After opening the cylinder cover 2, the moxa stick and the center insertion hole of the cut moxa stick can be aligned with the needle to fix them, so as to prevent the moxa material from tilting or tilting inside the cylinder and prevent the burning end from deviating and contacting the cylinder wall, causing local overheating.

[0033] The bottom opening of the moxibustion cylinder 1 is threaded internally, which is screwed onto the outer thread of the breathable mesh 3. The breathable mesh 3 is made of 304 stainless steel with a fine woven mesh and a mesh diameter of 0.8mm, which is smaller than the size of regular moxa ash particles. The ash that falls off when the moxa burns will be caught and blocked by the breathable mesh 3, and will not fall directly into contact with human skin, reducing the risk of burns from high-temperature moxa ash. The breathable mesh 3 can be unscrewed and disassembled, making it easy to clean up the accumulated moxa ash regularly and maintain smooth smoke circulation.

[0034] Preferred, such as Figures 1-7 As shown, the positioning and adjustment assembly is detachably fitted onto the outer wall of the moxibustion cylinder 1, and includes an elastic collar 4, several flexible connecting arms 5, and a suction cup 6.

[0035] The elastic collar 4 is a hollow annular rubber component that naturally contracts when opened without external force. Its inner diameter is 0.8 to 1.2 mm smaller than the outer diameter of the moxibustion cylinder 1. It tightly wraps the surface of the cylinder by relying on the elastic contraction force of the rubber itself. When sliding up and down manually, a slight external force needs to be applied. After sliding to the target height, it completes basic self-locking by relying on the static friction force of rubber contraction.

[0036] The inner wall of the elastic collar 4 is provided with an annular protrusion 7 extending along its circumference. The annular protrusion 7 extends continuously along the complete circumference of the collar. The cross-section of the annular protrusion 7 is semi-circular or trapezoidal. The annular protrusion 7 protrudes directly from the inner wall surface and fits tightly against the outer wall of the moxibustion cylinder 1, increasing the friction coefficient between the elastic collar 4 and the cylinder body, and further improving the self-locking stability after sliding positioning. During the moxibustion process, the weight of the moxibustion cylinder 1 and the pulling force of the flexible connecting arm 5 will not cause the elastic collar 4 to slide down on its own. No additional buckles or limiting structures are required for fixation, simplifying the overall number of parts.

[0037] Several flexible connecting arms 5 are distributed circumferentially along the elastic collar 4. Each flexible connecting arm 5 is a solid strip of highly elastic rubber. The rubber material is resistant to high temperature, tensile, and not easy to break after repeated bending. It will not harden or age quickly after long-term contact with the warm environment of moxa smoke.

[0038] The flexible connecting arm 5 is a strip of rubber. Each flexible connecting arm 5 is equally spaced around the side of the elastic collar 4. One end of the flexible connecting arm 5 is fixed to the elastic collar 4. In the unadsorbed state, the connecting end of the flexible connecting arm 5 and the side of the elastic collar 4 is set at an acute angle of 40°~50°. The connecting end of the flexible connecting arm 5 on the side of the elastic collar 4 points obliquely downward to the plane where the breathable mesh 3 is located. In the unadsorbed state, a basic pulling force is pre-formed to pull the moxibustion cylinder 1 downward. After the whole set of components is adsorbed onto the skin, the initial adhesion pressure can be generated without manual pulling, simplifying the operation steps.

[0039] The suction cup 6 is fixed to the elastic collar 4, and the other end can be attached to the surface of human skin. The suction cup 6 is a soft silicone bowl-shaped plate. The silicone material is skin-friendly and non-irritating, and is suitable for use on the surface of people with various skin types.

[0040] The end of the flexible connecting arm 5 that is away from the elastic collar 4 is connected to the outer wall of the suction cup 6 and coincides with the central axis of the suction cup 6. The flexible connecting arm 5 points obliquely upward from its connection end with the suction cup 6 towards the elastic collar 4.

[0041] The flexible connecting arm 5 and the axis of the suction cup 6 are set at an acute angle of 40°~50°. This angle design ensures that after the suction cup 6 is fully attached to the skin, the pulling force of the flexible connecting arm 5 acts perpendicularly to the tangent of the suction cup 6, weakening the lateral pulling force of the flexible connecting arm 5 on the suction cup 6, thereby reducing the probability of the suction cup 6 tipping over or detaching due to vacuum failure.

[0042] The inner wall of suction cup 6 is formed with multiple concentric circles of anti-slip adsorption texture. The texture increases the contact area between suction cup 6 and human skin. Even when there is sweat or oil on the skin, it can still maintain stable vacuum adsorption. It is not easy to fall off after long-term moxibustion. When removing suction cup 6, simply lift the edge of suction cup 6 to release the internal vacuum and it can be easily peeled off without tearing the skin keratin and hair. There is no problem of residual adhesive clogging pores like with traditional adhesive patches.

[0043] The flexible connecting arm 5, elastic collar 4, and suction cup 6 are integrally injection molded without any seams, preventing smoke and sweat from seeping into the components and causing aging. The entire positioning and adjustment assembly can be completely disassembled from the outer wall of the moxibustion cylinder 1. If a single suction cup 6 or flexible connecting arm 5 shows signs of aging, cracking, or adsorption failure, the entire positioning and adjustment assembly can be replaced directly. The main unit of the moxibustion cylinder 1 can be reused for a long time, reducing the cost of replacing consumables.

[0044] Preferred, such as Figures 1-4 As shown, the flexible connecting arm 5 acts as the hypotenuse of the triangle formed by the axis of the moxibustion cylinder 1, the human skin, and the flexible connecting arm 5. When the elastic collar 4 is at different positions on the outer wall of the moxibustion cylinder 1, the angle between the flexible connecting arm 5 and the axis of the moxibustion cylinder 1 changes. When the suction cup 6 is attached to the surface of the human skin and the flexible connecting arm 5 is in a tensioned state, the magnitude of the axial pressing force applied by the flexible connecting arm 5 to the moxibustion cylinder 1 on the side facing the human skin changes accordingly. Based on the principle of orthogonal decomposition of forces, the overall tension of the flexible connecting arm 5 can be decomposed into a vertically downward axial pressing force and a horizontally outward transverse force. The change in the angle value will synchronously change the magnitude of the axial pressing force, thereby steplessly adjusting the tightness of the fit between the breathable mesh 3 at the bottom of the moxibustion cylinder 1 and the human skin. The complete adjustment logic is as follows:

[0045] The elastic collar 4 slides to the upper end of the moxibustion cylinder 1, near the position of the cylinder cap 2, corresponding to the attached... Figure 2 Status: At this time, the elastic collar 4 is further away from the vertical distance of the human skin plane, the suction point of the suction cup 6 is offset inward relative to the axis of the moxibustion cylinder 1, the angle between the hypotenuse of the flexible connecting arm 5 and the vertical axis of the moxibustion cylinder 1 is the minimum value of the 30° adjustment range. The smaller the angle value, the vertical downward axial pressing force after the tension is decomposed is significantly increased, the lateral force ratio is reduced, and the axial pressing force is enhanced. The breathable mesh 3 at the bottom of the moxibustion cylinder 1 is tightly attached to the surface of the human skin, and there is almost no gap between the bottom of the cylinder and the skin. The smoke and warm medicinal power produced by the burning moxa are sealed in the narrow space inside the cylinder, the contact time between the smoke and the skin is extended, the medicinal power penetration effect is better, and at the same time, the smoke escapes outward and the amount of moxa smoke in the room is reduced. It is suitable for adult users who can tolerate high temperature and pursue strong physical therapy effect.

[0046] The elastic ring 4 slides to the lower end of the moxibustion cylinder 1, near the breathable mesh 3, corresponding to the attached position. Figure 3Status: At this time, the elastic collar 4 is closer to the vertical distance of the human skin plane, and the angle between the hypotenuse of the flexible connecting arm 5 and the vertical axis of the moxibustion cylinder 1 is 60°, which is the maximum value of the adjustment range. The larger the angle value, the smaller the vertical downward axial compression force after the tension is decomposed, the higher the proportion of the horizontal force, and the weaker the axial compression force. A small air gap will remain between the bottom air mesh 3 of the moxibustion cylinder 1 and the human skin. The high temperature heat generated by the burning moxa can be dissipated outward through the gap, and the heat intensity conducted to the skin is reduced, making the body surface feel more gentle. This is suitable for users with sensitive skin, the elderly, children, and those with weak heat tolerance who are new to moxibustion. At the same time, a small amount of smoke can be discharged through the gap to avoid the continuous accumulation of heat inside the cylinder, which may cause local burning discomfort.

[0047] When the elastic collar 4 slides at any midpoint between the upper and lower ends of the moxibustion cylinder 1, the angle between the flexible connecting arm 5 and the axis of the moxibustion cylinder 1 remains within the range of 30° to 60° and changes continuously. The axial pressing force increases and decreases synchronously and smoothly, without any sudden increase or decrease in force. Users can slowly and finely adjust the height of the elastic collar 4 according to their real-time temperature sensation to find a tightness that suits their own tolerance, thus achieving stepless and precise adjustment of the force.

[0048] Appendix Figure 4 This is a schematic diagram of the force breakdown surface. The central axis of the moxibustion cylinder 1 is marked with a vertical dotted line. The inclined sides of the three flexible connecting arms 5 at different heights correspond to the upper, middle, and lower adjustment positions of the elastic collar 4, respectively. The arrows indicate the vertical axial force and horizontal transverse force after the decomposition of the tension, intuitively demonstrating the mechanical change law that the larger the included angle, the smaller the vertical pressing force. The entire adjustment structure relies on pure mechanical geometry to achieve force adjustment, without the need for additional precision parts such as springs and adjustment knobs. The structure is simple and reliable, and it is not easy for parts to jam or be damaged.

[0049] The procedure for using this device is as follows:

[0050] Component Assembly: Hold the elastic collar 4 of the positioning and adjustment component, and spread the elastic collar 4 to both sides to increase the inner diameter of the elastic collar 4. Slide the collar down onto the outer wall of the moxibustion cylinder 1 from one end of the cap 2. After fully sliding it in, release the elastic collar 4. The rubber contraction force will then cover the cylinder, and the annular convex ridge 7 will adhere to the outer wall of the cylinder, completing the initial self-locking. After assembly, the overall structure is as follows: Figure 1 As shown, the assembly operation requires no tools or clips and can be completed within 10 seconds. The positioning component can be adapted to multiple moxibustion tubes with similar outer diameters, making it more versatile.

[0051] Filling with moxa: Pinch the top of the cap 2 and pull up the protrusion. Unscrew the cap 2 counterclockwise. Take the moxa stick or cut it into sections. Align the center hole of the moxa with the metal pin inside the cap 2. Press it vertically downwards to secure it. Make sure the burning end of the moxa is facing the bottom ventilation mesh 3. After lighting the burning end of the moxa, screw the cap 2 clockwise to close it. The threaded sealing structure of the cap 2 can reduce the amount of smoke overflowing from the top of the tube. The diamond-shaped through holes in the tube body help the smoke to be conducted downwards to the skin. The heat dissipation holes disperse the high temperature of the tube wall, and the basic anti-scalding effect is effective at the same time.

[0052] Surface adsorption positioning: Align the breathable mesh 3 at the bottom of the moxibustion cylinder 1 with the acupoints to be treated. Press the suction cups 6 on the outer periphery of the elastic ring 4 with both hands, and press firmly to completely adhere the surface of each suction cup 6 to the skin, thus expelling the air inside the suction cup 6 and forming a vacuum adsorption. The eight suction cups 6 are evenly distributed around the acupoints, and the multi-point simultaneous adsorption disperses the pulling force, so the moxibustion cylinder 1 is precisely fixed above the acupoints. The moxibustion cylinder 1 is not easy to shift during slight limb movements or turning over, and the precision of the fixed-point moxibustion is higher. The vacuum adsorption of the suction cups 6 replaces the traditional adhesive, leaving no adhesive residue and not damaging the skin.

[0053] Fine-tuning of the pressure: Adjust the height of the elastic ring 4 according to your own skin temperature sensation. If the skin feels hot and red, hold the elastic ring 4 with both hands and slide it down to the upper part of the breathable mesh 3. The angle between the flexible connecting arm 5 and the axis increases, the axial pressure decreases, and the moxibustion cylinder 1 forms a heat dissipation gap with the skin, gradually easing the body temperature. If the warmth is weak and the therapeutic effect is insufficient, hold the elastic ring 4 with both hands and slide it up to the lower part of the cylinder cover 2. The angle decreases, the pressure increases, the breathable mesh 3 fits the skin, and the smoke is retained to enhance the therapeutic effect. After sliding, release the elastic ring 4. The annular convex 7 rubs against the outer wall of the cylinder and locks itself. No manual support or fixation is required throughout the process, and the limbs can move freely.

[0054] Continuous moxibustion: After adjusting to the appropriate strength, maintain the device in an adsorbent state to complete the fixed-point moxibustion. During the moxibustion process, the heat dissipation holes of the tube continuously drain the high temperature of the outer wall, and the bottom breathable mesh 3 collects the moxa ash and isolates the high temperature residue. The adjustable pressure structure continuously weakens the burning stimulation. Multiple structures work together to reduce the probability of burns. The elastic collar 4 has a self-locking structure that will not slide on its own and maintains the set tightness throughout the process without the need for repeated adjustments.

[0055] Disassembly and cleaning: After moxibustion, lift the edge of each suction cup 6 in turn to release the vacuum inside the suction cup 6 and remove the entire set of instruments. Unscrew the cap 2 to take out the remaining moxa material. Unscrew the bottom ventilation mesh 3 to pour out the accumulated moxa ash inside. Rinse the ventilation mesh 3 and the inner wall of the moxibustion cylinder 1 with clean water and let them dry. If the suction force of the suction cup 6 decreases or the rubber ages and cracks, replace the entire positioning adjustment component. The main body of the moxibustion cylinder 1 can be reused, reducing the cost of consumables for long-term use. The entire set of components is compact after disassembly, does not take up space, and is convenient for home and travel use.

[0056] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
