Abstract
Description
Technical Field
[0001] This invention relates to the field of moxibustion products and their manufacturing technology, and in particular to a segmented moxibustion device that can permanently maintain the ultra-high compactness of moxa wool and actively control its combustion mode. Background Technology
[0002] High-density moxa sticks offer a longer-lasting and deeper moxibustion experience, and their preparation inevitably relies on high-pressure pressing technology. However, the well-known high-pressure moxa technology path in this field suffers from a fundamental contradiction that has long been difficult to overcome: it must involve three separate steps—"core making, demolding, and packaging." As an elastic plant fiber aggregate, moxa wool exhibits significant rebound after high-pressure demolding, resulting in a substantial decrease in its density, thus rendering the term "high-pressure moxa" misleading.
[0003] Meanwhile, both traditionally produced moxa sticks and those produced under high pressure exhibit a deeper physical defect during combustion: uncontrolled morphology of the burning end face. In unrestrained free combustion, the burning end face forms a sharp conical shape. This morphology leads to multiple drawbacks: 1. Low efficiency of effective thermal radiation: Moxibustion mainly relies on the far-infrared thermal radiation from the burning end face to act on acupoints. In the conical end face, only a very small area at the tip of the cone can provide efficient vertical radiation, while the sidewalls of the cone, which occupy most of the surface area, have a diffused thermal radiation direction, which cannot effectively act on the target acupoints, resulting in a huge waste of the heat energy of the moxa wool.
[0004] 2. Deterioration of the combustion process: The conical shape results in an excessively large actual surface area of the moxa wool participating in combustion per unit time, leading to "excessively fast combustion speed, shortened effective moxibustion time, and increased smoke production per unit time".
[0005] Therefore, this field has long faced a dual technical dilemma: first, how to permanently lock the maximum compactness of moxa wool after high-pressure pressing without the aid of adhesives? Second, how to actively control the shape of the combustion end face to keep it as a flat or convex surface with the highest heat radiation efficiency? Existing technologies are limited by the inherent thinking of "core making-demolding-packaging" and lack intervention methods for the physical process of combustion, thus failing to provide any effective solutions. Summary of the Invention
[0006] The purpose of this invention is to simultaneously overcome the problems of "demolding and rebound" in existing high-pressure moxibustion processes and "loss of control over the end face shape" during the burning of traditional moxa sticks, and to provide a systematic solution that can guarantee the quality and therapeutic efficacy of moxa sticks throughout the entire production and use cycle.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: A segmented self-restrained moxibustion device, characterized in that it comprises: Multiple tubular constraint segments are arranged axially and together form a continuous forming cavity for pressing the moxa stick. A moxa stick is integrally pressed from moxa wool within the continuous molding cavity under axial pressure. The plurality of tubular constraint segments are configured to be removed individually to expose the moxa stick segment by segment; When the tubular constraint segment at the front end is removed, the port of the adjacent subsequent tubular constraint segment forms a geometric constraint on the burning end face of the moxa stick, so that it remains planar or convex during the burning process.
[0008] The technical solution of this invention is based on a novel technical approach of "integrated pressing, never demolding, and removal as needed." The tubular constraint section constitutes a permanent constraint on the moxa stick from the moment it is pressed, fundamentally preventing demolding and springback. Only after the moxa wool has been heated and solidified within the combustion section, reducing its adhesion, can this tubular section be easily removed.
[0009] The tubular constraint sections can achieve integrity through various optional structural forms, including but not limited to: a stable column formed by the rigidity and static friction of the molded moxa stick; a tight connection through threads / clamps / magnetic attraction (a sealing ring can preferably be provided at the joint); or a connection achieved through an auxiliary connection mechanism. The auxiliary connection mechanism can be one or more connecting rods that penetrate all tubular constraint sections, and can be further optimized to use at least three circumferentially evenly distributed connecting rods to significantly improve structural stability; the connecting rod mechanism can be specifically defined as: passing through an axial through hole in the tube wall; passing through the inner hole of an independent annular part on the outside of the tube section; passing through the annular gap formed by the connecting sleeve on the outside of the tube section; or passing through a connecting part integrally formed with the outer wall of the tubular constraint section and having radial connecting ribs and axial gaps.
[0010] "The tubular constraint section is preferably a metal section, which utilizes its excellent thermal conductivity, structural strength and non-flammability to achieve a long-lasting, deep and efficient heat therapy experience. This is the preferred solution for achieving the best technical effect of the present invention."
[0011] It is understandable that, to meet different user preferences and market demands, such as those seeking the tactile feel of natural materials or achieving specific aesthetics and playability, the material of the tubular constraint segment is not limited to metal. Provided sufficient pressing strength and heat resistance are available, other materials can also be used, such as ceramics, or dense wood or bamboo treated with carbonization processes.
[0012] For natural fiber materials such as wood and bamboo, the technical feasibility is ensured based on the following core concepts: First, in the production process, the radial constraint of the external clamps ensures that the structure remains intact during high-pressure pressing; after molding, the inherent rigidity of the moxa stick and the static friction with the tube wall become the main mechanical support for maintaining its shape. Second, in the usage process, the smoldering (burning without open flame) characteristics of moxa wool and the fact that its combustion end face is geometrically restricted by the constrained section end mean that the tube body only bears heat radiation and conduction, rather than direct flame burning, and its temperature rise is within a controllable range. In addition, in the implementation using connecting rods, the multi-rod through-hole structure itself provides additional structural reinforcement to the whole.
[0013] Therefore, using pipe sections made of natural materials such as wood and bamboo is technically feasible and can open up a high-end product line that is different from the cold industrial feel and has a more humanistic warmth and natural affinity, which is an important expansion of the application scope of this invention.
[0014] The moxa stick is preferably made from pure moxa wool pressed without the addition of adhesives.
[0015] The length of a single tubular constraint segment is preferably between 1 cm and 3 cm, and more preferably 2 cm. As an important optimization, the length of the foremost tubular constraint segment is preferably 1 cm to facilitate easy removal after initial ignition.
[0016] A method for preparing the segmented self-constraining moxibustion device is characterized by the following steps: arranging multiple tubular constraint segments axially to form a continuous molding cavity; filling the cavity with moxa wool; and applying axial pressure (preferably 5-20 MPa) to the moxa wool to integrally mold it into a moxa stick. In this pressing step, an external clamp can preferably be used to radially constrain the arranged tubular constraint segments, and the clamp is removed after the moxa stick is pressed into shape.
[0017] The beneficial effects of this invention are as follows: 1. Integrated Solution to Two Technical Challenges: By employing the core concept of "segmented removable constraint bodies as a unified carrier for integrated molding, anti-springback structure, and dynamic combustion pattern controller," two independent technical problems that have long plagued this field have been overcome in one fell swoop. In the production stage, springback is eliminated and permanently locked in a "never-demolding" manner; in the usage stage, the geometric boundaries of the constraint segments control the shape, achieving efficient combustion.
[0018] 2. Controlling Combustion Pattern to Enhance Thermal Efficiency and User Experience: By constraining the geometric boundaries of the combustion section, a flat or convex high-efficiency combustion end face is actively shaped and maintained. According to infrared thermal radiation theory, compared to a conical source, the radiated energy of a planar or convex source is more concentrated in the normal direction, conforming to Lambert's cosine law, thus significantly improving the vertical radiation efficiency to the acupoint and fundamentally avoiding the formation of an ineffective conical shape. Simultaneously, this achieves the excellent effects of extending the effective combustion time and reducing the amount of smoke produced per unit time.
[0019] 3. Dynamic constraint, unimpeded thermal: As combustion progresses, the constraint section of that section is removed non-destructively, the combustion surface is fully exposed, and the thermal radiation efficiency reaches its peak.
[0020] 4. One-piece molding, stable structure: The moxa stick is formed under high pressure in one go within the assembled long cavity, resulting in a seamless and extremely high-density rod that ensures the stability and continuity of combustion.
[0021] 5. Diverse modes and precise control: Supports multiple modes such as no connection, direct connection, and auxiliary connection, allowing users to intuitively control the combustion progress and providing a strong sense of ritual and control during use. Attached Figure Description

[0031] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the present invention provides a systematic solution encompassing various optional structures designed to achieve "never demolding" and "removal on demand." These structural forms are determined during the production stage and persist into the use stage.
[0032] Implementation Method 1 (Mechanically Stable Form): Multiple independent metal tubular constraint segments (1) are axially aligned in a mold to form a continuous cavity. Moxa wool is filled into the cavity and pressurized under high pressure to form a monolithic moxa stick (2). This production method directly results in the final device form: relying on the extremely high rigidity of the moxa stick (2) itself and the huge static friction force generated between it and the inner wall of each tubular segment (1), all components are combined into a handheld, stable cylindrical whole without any external connecting mechanism.
[0033] Implementation Method 2 (Threaded Connection): During production, the tubular constraint section (1), which has external threads at one end and internal threads at the other end, is screwed together to embed a sealing ring, forming a cavity with strong integrity and good sealing performance. Then, filling and pressing are performed. This production method directly results in the final device form: a tubular whole tightly connected by threads.
[0034] Implementation Method 3 (Rod Connection): During production, multiple tubular constraint segments (1) are axially aligned using an auxiliary connecting mechanism. The auxiliary connecting mechanism includes a connecting rod (3) and an annular positioning structure located outside the tubular constraint segments (1). All tubular constraint segments (1) are threaded onto the connecting rod (3) and both ends are fixed, followed by filling and pressing. This production method directly results in the final device form: a whole maintained axially aligned by a central rod and an external annular positioning structure.
[0035] As a key optimization of this scheme, at least three circumferentially evenly distributed connecting rods (3) can be preferred. This design can form a stable spatial support structure, effectively preventing relative rotation or radial offset between the tubular constraint sections (1), thereby greatly enhancing the overall rigidity and stability of the device.
[0036] The ring-shaped positioning structure is a general term for all structures set outside the pipe section for the connecting rod to pass through to achieve axial positioning. Its specific implementation methods include, but are not limited to, the following embodiments.
[0037] Example 4 (Pipe Segment Length Optimization Example): This embodiment details the optimized selection of the length of the tubular constraint segment (1) and its physical basis. As the best practice of this invention, the length of a single segment of the tubular constraint segment (1) is determined to be 2 cm. This optimization is based on the core physical mechanism revealed by this invention: the easy removal of the segment depends on the volume shrinkage and significant reduction in adhesion of the moxa wool inside after it is heated and solidified. After repeated verification, controlling the length of a single segment within the range of 1-3 cm ensures that most of the moxa wool inside the segment has been fully heated and solidified by the end of the burning process, resulting in uniform and significantly reduced adhesion. Among these, 2 cm is the optimal solution that simultaneously ensures ease of operation, sufficient heat penetration time, and the best effect in reducing adhesion.
[0038] As a further optimization of the present invention, the length of the first tubular constraint segment (1) at the very front can be specially designed to be 1 cm, while the subsequent segments remain at 2 cm. This design is based on the finding that during the initial ignition stage, the entire device is at room temperature and there is insufficient heat accumulation. The shorter 1 cm first segment ensures that, under conditions of relatively low initial heat, the moxa wool inside can also complete the heat curing process quickly and evenly, and the adhesion is simultaneously reduced to a minimum, thereby achieving extremely easy removal of the first segment and laying a good foundation for subsequent use by the user.
[0039] Example 5 (Optimized Example of Connecting Rod Structure): This embodiment details several preferred specific structures of the auxiliary connection mechanism of the connecting rod (3).
[0040] Example 5A (Built-in Axial Hole Type): As a preferred embodiment of the present invention, an axial through hole (7) can be opened in the pipe wall of the tubular constraint section (1), and the axis of the through hole is located on the radial center line of the pipe wall. During assembly, the connecting rod (3) is passed through the corresponding axial through holes (7) on all pipe sections in sequence. This structure allows the connecting rod to be completely concealed within the pipe wall, resulting in a simple appearance and effectively preventing relative rotation between pipe sections.
[0041] Example 5B (External Ring-shaped Part): As another preferred embodiment of the present invention, an independent ring-shaped part is sleeved on the outside of the tubular constraint section (1), and the inner hole of the ring-shaped part cooperates with the connecting rod (3).
[0042] Example 5C (sleeve-through type): As another preferred embodiment of the present invention, a dual structure combining a connecting sleeve and a tubular constraint section (1) can be adopted.
[0043] Type C1 (split sleeve type): Use an independent connecting sleeve with an inner diameter slightly larger than the outer diameter of the tubular constraint section (1). Insert the tubular constraint section (1) into the connecting sleeve in sequence, so that an annular gap is formed between the inner wall of the connecting sleeve and the outer wall of the tubular constraint section (1) for the connecting rod (3) to pass through.
[0044] Type C2 (Integrated): More preferably, the tubular constraint section and the connecting sleeve are integrally formed into an "integrated constraint tube section (6)" through a profile process. This component connects the inner wall (constraint cavity) and the outer wall through radial connecting ribs (61), thereby naturally forming an axially extending gap (62) through which the connecting rod (3) passes. This solution provides a through axial channel while maintaining the ultimate integrity of the structure, and the assembly process is more simplified.
[0045] Example 6 (Example of an optimized manufacturing process with external fixtures): This embodiment details a method for optimizing the pressing process of the segmented self-constraining moxibustion device. Before filling and high-pressure pressing after arranging multiple tubular constrained segments (1) to form a continuous molding cavity, a key step can be added: using a dedicated external clamp (5) to temporarily externally bind or hoop the entire tubular assembly (e.g., ...). Figure 4 (As shown).
[0046] The function of the external clamp (5) is: 1. Ensure concentricity and straightness: Under the huge axial force of high pressure, prevent radial misalignment or axial bending of each pipe section, and ensure that the final formed moxa stick (2) is straight and uniform.
[0047] 2. Enhanced cavity sealing: For a "mechanically stable state" maintained by friction, the external clamps can ensure that the joints of each pipe section are tight and seamless, preventing high-pressure moxa wool from being squeezed out from the joints and ensuring molding quality.
[0048] 3. Protect the pipe section structure: For thin tubular constraint sections (1) made of non-metallic materials, external clamps can prevent them from cracking or plastic deformation under high pressure.
[0049] The optimized production process is as follows: arrange pipe sections → apply external clamps (5) → fill with moxa wool → axial high pressure pressing → release and remove external clamps (5) after molding. After this, the device enters a certain stable operating state as described above.
[0050] How to use: The segmented self-restrained moxibustion device prepared according to any of the aforementioned embodiments is used based on the physical mechanism of "volume shrinkage and reduced adhesion after the moxa wool is heated and solidified," and the specific process is as follows: 1. Initial ignition: Directly ignite the end face of the moxa stick (2) at the port of the foremost tubular constraint section (1).
[0051] 2. First section heating and curing: The high temperature generated by combustion causes the moxa wool in the first tubular constraint section (1) to be heated and cured, shrinking in volume, resulting in a gap between it and the tube wall, and significantly reducing the adhesion.
[0052] 3. Removal of the first section and exposure of the new surface: When the moxa wool in the first tubular confined section (1) has been sufficiently heated and cured to a degree that it is easy to remove, it can be easily removed axially. This operation fully exposes the new combustion end face with the cured layer substrate that was originally in the position of the first section.
[0053] 4. Secondary Constraint and High-Efficiency Combustion: At this point, the port of the original second tubular constraint section (i.e., the new foremost section) immediately forms a geometric constraint on this newly exposed combustion end face (4). Under this constraint, the combustion end face is forcibly shaped and maintained as a plane or convex surface with the highest thermal radiation efficiency, fundamentally avoiding the formation of "cone-shaped" combustion (e.g., Figure 3 (As shown).
[0054] 5. Iterative Process: When the burning progresses to a point where it is nearly flush with the port of the new foremost tubular constraint segment, and the moxa wool has reached a state where it can be easily removed as described in step 3, repeat steps 3 and 4 to remove the tubular segment, making the ports of its subsequent segments the new constraint boundaries. Continue this cycle until all the moxa sticks have been used.
[0055] It should be understood that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention, and the scope of protection of the present invention should be determined by the scope of the claims.
