Description

Technical Field

[0001] This invention belongs to the field of moxibustion, and specifically relates to a handheld moxibustion device. Background Technology

[0002] Moxibustion, an important external therapy in Traditional Chinese Medicine, involves burning moxa sticks and applying heat stimulation to specific acupoints or affected areas to achieve therapeutic effects such as warming the meridians and dispelling cold, promoting qi and blood circulation, and strengthening yang and consolidating the body. Due to its ease of use and significant effects, it is widely popular and is extensively used in home healthcare and clinical treatment.

[0003] Traditional moxibustion methods primarily rely on holding moxa sticks directly to acupoints for indirect application. However, these traditional methods have several inherent drawbacks. First, when using handheld moxa sticks for indirect application, it is difficult for the operator to maintain a stable distance and posture for extended periods, leading to fluctuating temperatures that affect the therapeutic effect. Furthermore, prolonged use can cause arm fatigue. Second, the ash produced during combustion poses a risk of falling off and burning the user's skin, creating a safety hazard. Additionally, during natural combustion, the heat and effective smoke substances (volatile compounds) diffuse haphazardly in all directions, with most failing to reach the target area, resulting in a waste of heat energy and moxa material.

[0004] To overcome these shortcomings, some auxiliary moxibustion devices have emerged on the market. For example, while moxibustion boxes can fix the moxa stick and collect the ash, they mostly rely on natural heat convection, resulting in weak heat penetration and uneven distribution. Furthermore, the enclosed space can easily lead to insufficient oxygen supply to the moxa stick, causing it to extinguish midway.

[0005] Therefore, a handheld moxibustion device is needed to overcome the above problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a handheld moxibustion device, which achieves the objective of resolving the issues raised in the background section.

[0007] To achieve the above objectives, the present invention employs the following technical solution: a handheld moxibustion device, comprising: a shell, with an internally interconnected air inlet and air outlet; a fan disposed within the shell for driving air to enter from the air inlet and flow out from the air outlet to form an airflow; and a storage section disposed at the air outlet for accommodating moxa sticks; wherein the airflow flowing out from the air outlet is heated by a heating wire to form a hot air curtain to envelop the area to be treated with moxibustion with the heat and volatile substances generated by the burning moxa sticks.

[0008] As a further improvement to the above technical solution: The housing has a first chamber connected to the air outlet and a second chamber for accommodating the control circuit board. Part of the air entering through the air inlet is directed into the second chamber to dissipate heat from the control circuit board, and then flows into the first chamber.

[0009] The outer shell also has a third chamber, which is connected to the first chamber and the storage section; the air entering the third chamber from the first chamber is used to supply oxygen to the moxa stick in the storage section to achieve combustion.

[0010] The storage unit includes: a shell having an interior space for accommodating moxa sticks, wherein the side wall or bottom of the shell has a vent hole communicating with the third chamber; and a protective cover detachably installed at the opening of the shell to prevent moxa ash from falling and to prevent the burning moxa sticks from scalding the area to be treated.

[0011] The first chamber is equipped with a flow guide shroud to ensure that the airflow from the outlet is evenly distributed.

[0012] A heating wire is installed inside the air guide hood. The airflow from the air outlet is heated by the heating wire to form a hot air curtain that acts on the area to be treated with moxibustion.

[0013] The storage section is located at the center of the air outlet so that the airflow can envelop the area to be treated with moxibustion with the heat and volatile substances generated by the burning moxa stick.

[0014] The air inlet is equipped with a filter structure for filtering the air entering the air inlet.

[0015] The filtration structure includes: a second filter screen that can be detachably installed outside the air inlet; a first filter screen covering the second filter screen; and a honeycomb support frame disposed inside the housing and located on the air inlet side of the fan.

[0016] The mesh count of the first filter screen is smaller than that of the second filter screen, so as to achieve step-by-step filtration of the air entering the air inlet.

[0017] An infrared light curtain generator is installed at the air outlet. The infrared light curtain acts on the area to be treated with moxibustion, and the heat generated by the burning moxa stick can be kept within the infrared light curtain to apply heat to the area to be treated with moxibustion.

[0018] The present invention also proposes the following technical solutions: A method for performing moxibustion using the aforementioned handheld moxibustion device includes the following steps: placing the moxa stick in the storage compartment and igniting it; starting the fan to generate an airflow that is heated by a heating wire and flows out from the air outlet; and aligning the air outlet with the area to be treated, so that the airflow delivers the heat and volatile substances generated by the burning moxa stick to the area to be treated.

[0019] The beneficial effects of the embodiments of the present invention are as follows: This application utilizes the combination of the outer shell, fan, heating wire, and storage unit to form an actively controlled airflow, which evenly delivers the heat and volatile substances generated by the burning moxa stick to the area to be treated with moxibustion. It has the advantages of stabilizing the moxibustion temperature, preventing burns from moxa ash, and efficiently delivering heat and volatile substances. Once the moxa stick is ignited in the storage compartment, the airflow generated by the fan not only provides the oxygen needed for combustion, but more importantly, it effectively captures the heat and volatile substances released during combustion. The airflow entrains the heat and smoke particles. Subsequently, these carried substances are precisely directed to the area to be treated with moxibustion. This forced convection ensures that the thermal and medicinal effects of moxibustion are concentrated, evenly, and deeply applied to the target area, avoiding the disorderly diffusion of heat and smoke in traditional moxibustion. During normal operation, the fan-driven airflow of the handheld moxibustion device is not only used for moxibustion but also partially diverted to provide continuous cooling for the control circuit board. This design ensures that the control circuit board remains at a suitable operating temperature, effectively preventing performance degradation or malfunctions caused by overheating, thus significantly improving the reliability, stability, and lifespan of the handheld moxibustion device. Simultaneously, the cooled air is reintegrated into the main airflow, eliminating the need for additional exhaust vents, resulting in a more compact internal structure and improved energy efficiency. This handheld moxibustion device achieves directional and continuous oxygen supply to the moxa stick combustion area by introducing a third chamber and effectively connecting it to the first chamber and storage section. The fan-driven airflow, after passing through the first chamber, is partially guided into the third chamber and ultimately delivered to the moxa stick in the storage section. This design ensures that the moxa stick continuously receives sufficient oxygen during combustion, maintaining a stable and complete combustion state. Complete combustion of the moxa stick not only generates more stable heat, improving the warming effect of moxibustion, but also promotes the complete combustion and volatilization of the effective components in the moxa wool, enhancing the penetration of medicinal effects. Simultaneously, the stable combustion state avoids the problem of the moxa stick extinguishing due to lack of oxygen or uneven combustion, improving the reliability of the moxibustion device and the user experience, making the moxibustion process more efficient and comfortable.

Detailed Implementation

[0022] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0023] See Figures 1 to 2 This invention discloses a handheld moxibustion device, comprising: a shell 1, with an air inlet 2 and an air outlet 3 interconnected inside; a fan 4 disposed inside the shell 1 for driving air to enter from the air inlet 2 and flow out from the air outlet 3 to form an airflow; and a storage part 5 disposed at the air outlet 3 for holding moxa sticks; wherein the airflow flowing out from the air outlet 3 carries the heat and volatile substances generated by the burning of the moxa sticks and acts on the area to be treated with moxibustion.

[0024] For ease of understanding, the following explains some key terms in this embodiment: The outer casing 1 refers to the external structure of the device, which is usually made of heat-resistant and insulating materials to protect the internal components and provide convenience for handheld operation. Its internal space is designed to accommodate the fan 4, the storage section 5, and channels for air circulation.

[0025] The air inlet 2 refers to the opening or channel on the outer casing 1 for external air to enter the device. Its function is to provide an air source for the fan 4 to form the subsequent airflow.

[0026] The air outlet 3 refers to the opening or channel on the outer casing 1 through which the internal air of the device flows out and acts on the area to be treated with moxibustion. This air outlet 3 is the key outlet for the airflow to carry the moxibustion products to the target area.

[0027] Fan 4 refers to a power device, such as a miniature fan, whose function is to generate airflow, drive air to enter from the air inlet 2, pass through the inside of the device, and be discharged from the air outlet 3, thereby forming a directional airflow.

[0028] Storage section 5 refers to the structure used to place and fix the moxa stick. It is usually designed to withstand the high temperature generated by the burning of the moxa stick and to ensure that the moxa stick is stably located in the airflow path during the burning process.

[0029] Airflow refers to the flow of air with a specific direction and speed, driven by the fan 4. In this device, the airflow has two main functions: first, to aid in the combustion of the moxa stick; and second, to form an annular air curtain after being heated by the heating wire, effectively transporting the heat and volatile substances generated by the burning moxa stick to the area to be treated.

[0030] Moxa cones are cylindrical or conical burning materials made of mugwort, which serve as carriers for the heat and medicinal substances produced in moxibustion therapy.

[0031] Heat and volatile substances refer to the energy released during the burning of moxa sticks and the pharmacologically active smoke components. These substances are the core elements for moxibustion to exert its therapeutic effects.

[0032] The area to be treated with moxibustion refers to the specific acupoints, meridians, or lesions on the human body that require moxibustion treatment.

[0033] The outer casing 1 serves as the external structure of the device, and its internal space is designed to form an interconnected air inlet 2 and air outlet 3. The material of the outer casing 1 can include high-temperature resistant plastic, ceramic, or metal to ensure structural integrity and safe use. The air inlet 2 and air outlet 3 can be formed by directly creating openings in the outer casing 1. The air inlet 2 is typically located at the bottom or side of the outer casing 1 to introduce external air. The air outlet 3 is generally located at the front of the outer casing 1, facing the target acupuncture area. An airflow path is established between the air inlet 2 and the air outlet 3 through channels within the outer casing 1.

[0034] The fan 4 is positioned within the airflow path inside the housing 1, specifically behind the air inlet 2 or in front of the air outlet 3. The fan 4 can be an axial fan, centrifugal fan, or turbine fan, selected based on the required airflow, air pressure, and the size limitations of the device. The fan 4 is electrically powered to rotate its blades, thereby generating directional airflow. The fan 4 can be fixed to a support structure inside the housing 1 and is electrically connected to a power supply and control module. When the fan 4 is started, outside air is drawn into the air inlet 2, accelerated by the fan 4 to form a kinetic airflow, and guided to the air outlet 3.

[0035] The storage section 5 is located in the area of ​​the air outlet 3. Its function is to provide a stable space for the moxa stick and ensure that the heat and volatile substances generated by the burning moxa stick can be effectively carried away by the airflow. The structure of the storage section 5 can be a metal mesh basket or a bracket with a snap-fit ​​function, and its material must have high-temperature resistance. The storage section 5 can be fixed near the air outlet 3 so that the combustion area of ​​the ignited moxa stick is within the direct range of airflow.

[0036] Once the moxa stick is ignited in the storage section 5, the airflow generated by the fan 4 not only provides the oxygen needed for combustion, but more importantly, it effectively captures the heat and volatile substances released during combustion. The airflow entrains the heat and smoke particles. Subsequently, these carried substances are precisely directed to the area to be treated with moxibustion. This forced convection ensures that the thermal effect and medicinal properties of moxibustion are concentrated, evenly, and deeply applied to the target area, avoiding the disorderly diffusion of heat and smoke in traditional moxibustion.

[0037] The handheld moxibustion device proposed in this application uses a fan 4 to drive airflow, which can directionally and effectively deliver the heat and volatile substances generated by the burning moxa stick to the area to be treated. This overcomes the waste caused by the disordered diffusion of heat and effective substances in traditional moxibustion, and achieves stable control of the moxibustion temperature and enhanced heat penetration.

[0038] In practical applications of handheld moxibustion devices, the control circuit board, as a core electronic component, generates heat during operation. If this heat cannot be dissipated effectively and in a timely manner, it may cause the circuit board to overheat, thereby affecting the stability and lifespan of the device. Furthermore, the burning moxa sticks inside the moxibustion device further contribute to overheating when their high temperature is transferred to the control circuit board. To address this, this application proposes a handheld moxibustion device with a first chamber 6 connected to an air outlet 3 and a second chamber 7 for housing the control circuit board. Simultaneously, some of the air entering through the air inlet 2 is directed into the second chamber 7 to dissipate heat from the control circuit board before flowing back into the first chamber 6.

[0039] Specifically, the first chamber 6 is a main space inside the outer shell 1, designed to guide the airflow driven by the fan 4, enabling it to flow effectively to the air outlet 3 and ultimately carry the heat and volatile substances generated by the burning moxa stick through the storage section 5. The arrangement of the first chamber 6 makes the airflow path inside the device more defined and controllable. For example, the first chamber 6 can be a relatively spacious passage to ensure smooth airflow and reduce resistance. The second chamber 7 is a space inside the outer shell 1 specifically designed to house the control circuit board. The control circuit board is the core electronic component of the handheld moxibustion device, responsible for managing the operation of the fan 4, temperature control, power management, and user interface functions. Placing the control circuit board in a separate second chamber 7 provides physical protection and a relatively independent working environment. The second chamber 7 can be a compact compartment, its size and shape designed according to the actual size and layout of the control circuit board it houses.

[0040] To effectively dissipate heat from the control circuit board, a portion of the external cool air drawn in from the air inlet 2 is purposefully guided to the second chamber 7. This ensures that the cool air flows directly over or near the surface of the control circuit board, carrying away the heat generated during its operation. The air introduced into the second chamber 7 primarily functions as a cooling medium, transferring the heat generated by the control circuit board to the air through convection heat transfer. This heat dissipation mechanism helps maintain the control circuit board within a safe operating temperature range, preventing performance degradation or damage due to overheating, thus ensuring the long-term stable operation of the device. After the air has cooled the control circuit board in the second chamber 7, its temperature will be slightly higher, but it can still be used as part of the subsequent airflow. This portion of air is then guided and merged into the first chamber 6. This design allows the air used for cooling the control circuit board to be reused, mixing with the main airflow driven by the fan 4 and flowing together towards the air outlet 3. This merging mechanism avoids the separate exhaust of cooling air, simplifies the internal structure, and ensures the continuity and efficiency of the overall airflow.

[0041] Through the above technical solution, during normal operation, the airflow driven by fan 4 in the handheld moxibustion device is not only used for moxibustion but also partially diverted to provide continuous cooling for the control circuit board. This design ensures that the control circuit board remains at a suitable operating temperature, effectively preventing performance degradation or malfunctions caused by overheating, thus significantly improving the reliability, stability, and lifespan of the handheld moxibustion device. Simultaneously, the cooled air is reintegrated into the main airflow, eliminating the need for additional exhaust vents, resulting in a more compact internal structure and improved energy efficiency.

[0042] In some embodiments of this application, the handheld moxibustion device uses a fan 4 to drive airflow and utilizes a portion of the airflow to dissipate heat from the control circuit board. However, during the burning of the moxa stick, if there is a lack of sufficient and stable oxygen supply, the moxa stick may burn incompletely, have insufficient heat, or extinguish, thereby affecting the moxibustion effect and failing to effectively release the medicinal components and heat of the moxa stick.

[0043] In this regard, this application further proposes that a third chamber 8 is provided inside the outer shell 1, the third chamber 8 is connected to the first chamber 6 and the storage part 5; the air entering the third chamber 8 from the first chamber 6 is used to supply oxygen to the moxa stick in the storage part 5 to achieve combustion assistance.

[0044] Specifically, the third chamber 8 is an independent space located inside the outer shell 1, and its main function is to serve as a dedicated channel for combustion air. The third chamber 8 is connected to the first chamber 6, meaning that the source of the combustion air is the main airflow driven by the fan 4. This connection can be achieved by creating one or more through-holes in the side wall or bottom of the first chamber 6 to ensure that the air diverted from the first chamber 6 has sufficient pressure and flow rate. Simultaneously, the third chamber 8 is also connected to the storage section 5 to directly deliver the combustion air to the combustion zone of the moxa stick. This connection can be achieved by creating vents or a mesh structure in the side wall, bottom, or area adjacent to the third chamber 8 of the storage section 5 to ensure that air can evenly contact the moxa stick within the storage section 5, thereby promoting complete combustion of the moxa stick.

[0045] Through the aforementioned technical solution, the handheld moxibustion device, by introducing a third chamber 8 and effectively connecting it to the first chamber 6 and the storage section 5, achieves directional and continuous oxygen supply to the moxa stick combustion area. The airflow driven by the fan 4, after passing through the first chamber 6, is partially precisely guided into the third chamber 8 and ultimately delivered to the moxa stick in the storage section 5. This design ensures that the moxa stick continuously receives sufficient oxygen during combustion, thus maintaining a stable and complete combustion state. Complete combustion of the moxa stick not only generates more stable heat, improving the warming effect of moxibustion, but also promotes the complete combustion and volatilization of the effective components in the moxa wool, enhancing the penetration of medicinal effects. Simultaneously, the stable combustion state avoids the problem of the moxa stick extinguishing due to lack of oxygen or uneven combustion, improving the reliability of the moxibustion device and the user experience, making the moxibustion process more efficient and comfortable.

[0046] In some embodiments of this application, the handheld moxibustion device contains moxa sticks in the storage section and uses airflow to assist combustion. However, during the burning of the moxa sticks, the ash may be scattered with the airflow, and the burning moxa sticks pose a risk of scalding the user or the area to be treated. In this regard, this application further proposes a specific structure for the storage section 5, which includes a housing 51 and a protective cover 52.

[0047] The housing 51 of the storage section 5 is the core structure that directly supports and fixes the moxa stick. Its internal space is designed to stably accommodate the moxa stick, ensuring that it remains in the predetermined position when the moxibustion device is in operation. The housing 51 is typically made of high-temperature resistant materials, such as ceramics, metal alloys, or special heat-resistant composite materials, to withstand the high temperatures generated by the combustion of the moxa stick. To effectively aid combustion of the moxa stick, ventilation holes are provided on the side walls or bottom of the housing 51. These ventilation holes communicate with the aforementioned third chamber 8, allowing oxygen-rich air introduced from the third chamber 8 to enter the interior of the housing 51 through these holes and directly contact the moxa stick, thereby providing sufficient oxygen for stable combustion. The distribution and size of the ventilation holes can be optimized according to the combustion characteristics of the moxa stick and the required combustion-aiding effect to ensure smooth airflow and optimal combustion-aiding effect.

[0048] The protective cover 52 is a protective component installed at the opening of the housing 51. It is designed to be detachable, for example, by screw-on engagement, snap-fit ​​fixing, magnetic connection, or plug-in structure, allowing users to easily replace burnt moxa sticks or clean up moxa ash. The main functions of the protective cover 52 are to provide safety protection and environmental cleanliness. On one hand, it effectively prevents the moxa ash produced during the burning process from being scattered by the airflow, avoiding contamination of the moxibustion environment or irritation to the user's skin. To this end, the protective cover 52 can adopt a fine mesh structure, a perforated plate, or a design with specifically shaped openings, allowing heat and volatile substances to pass through while effectively trapping moxa ash. On the other hand, the protective cover 52 forms a physical barrier during moxibustion, preventing the burning moxa stick from directly contacting the area to be treated or the user's skin, thus avoiding the risk of burns. The material of the protective cover 52 usually also has a certain degree of heat insulation, and its structural design ensures a safe distance between the area to be treated and the burning moxa stick, further enhancing safety.

[0049] Through the above technical solution, the storage section 5 is specifically designed to include a shell 51 and a protective cover 52. This application effectively solves the risks of moxa ash scattering and burns during moxibustion. The space formed inside the shell 51 can stably accommodate the moxa stick, while the ventilation holes on its side walls or bottom ensure that the combustion air from the third chamber 8 can be fully and evenly supplied to the moxa stick, thereby promoting stable combustion of the moxa stick. At the same time, the detachable protective cover 52 can not only effectively prevent the moxa ash produced by the burning moxa stick from scattering with the airflow and keep the moxibustion environment clean, but also form a physical barrier during moxibustion to prevent the burning moxa stick from directly contacting the area to be treated, thereby avoiding the risk of burns and significantly improving the safety and user experience of moxibustion.

[0050] This application further proposes to provide a flow guide shroud 10 in the first chamber 6 to make the airflow from the air outlet 3 evenly distributed.

[0051] The airflow guide 10 is a structure used to guide and regulate the direction and distribution of fluid (here referring to airflow). It is typically made of materials with specific shapes and dimensions, such as plastics, metals, or composite materials. The airflow guide 10 can be designed in various geometries, such as conical, mesh-like, honeycomb-like, or structures with guide vanes, to adapt to different airflow characteristics and space constraints. Its main function is to eliminate eddies or non-uniformities in the airflow by changing the flow path and velocity distribution, thereby achieving a more uniform distribution of the airflow before it leaves the outlet 3. Uniform airflow distribution at the outlet 3 means that the velocity of the airflow is as consistent as possible spatially as it passes through the cross-section of the outlet 3. Achieving uniform airflow distribution is crucial for handheld moxibustion devices because the therapeutic effect of moxibustion depends on the stable and uniform transfer of heat and active ingredients. Through the action of the airflow guide 10, airflow concentration in a certain area or the formation of dead zones can be effectively avoided, ensuring that the heat and volatile substances generated by the burning moxa stick can act uniformly on the treatment site in a stable and controllable manner, thereby improving the therapeutic effect and safety of moxibustion.

[0052] Through the above technical solution, a guide hood 10 is installed in the first chamber 6, which can effectively guide and regulate the airflow from the air outlet 3. The guide hood 10, through its specific structural design, can eliminate eddies or unevenness that may occur in the airflow within the first chamber 6, thereby ensuring that the airflow has a highly uniform velocity when leaving the air outlet 3. This uniform airflow can more stably and consistently deliver the heat and volatile substances generated by the burning moxa stick to the area to be treated, avoiding problems such as local overheating or insufficient treatment caused by uneven airflow. Therefore, this application significantly improves the comfort, safety, and effectiveness of moxibustion treatment, making the therapeutic effect of moxibustion more controllable and reliable.

[0053] This application further proposes that the storage section 5 is located at the center of the air outlet 3, so that the airflow can cover the area to be treated with moxibustion with the heat and volatile substances generated by the burning moxa stick. Specifically, "center location" means that the storage section 5 is arranged at or near the geometric center of the cross-section of the air outlet 3. This arrangement ensures that the area where the moxa stick is burning is highly aligned with the airflow path of the air outlet 3. This centralized arrangement aims to optimize the contact efficiency and mixing uniformity between the airflow and the products of moxa stick combustion.

[0054] By placing the storage section 5 at the center of the air outlet 3, the heat and volatile substances generated by the burning moxa stick can directly and fully contact and mix with the airflow exiting the air outlet 3. Because the moxa stick is located in the core area of ​​the airflow, the airflow can carry these combustion products in a more uniform and efficient manner. This effectively avoids the problems of uneven airflow carrying and uneven distribution of heat and effective components caused by the storage section 5 being off-center.

[0055] In some embodiments described above in this application, a handheld moxibustion device is proposed, which uses a fan 4 to drive airflow to carry the heat and volatile substances generated by the burning moxa stick to the area to be treated. However, in actual use, the air drawn into the device from the external environment may contain particulate matter such as dust and impurities. These particulate matter may not only contaminate the inside of the device, affecting the normal operation and service life of components such as the fan 4, but may also mix with the substances generated by the burning moxa stick, reducing the purity and effectiveness of the moxibustion.

[0056] To address this, this application further proposes a filter structure 9 at the air inlet 2 for filtering the air entering the air inlet 2. The filter structure 9 is designed to remove particulate matter and impurities from the air entering the air inlet 2. The filter structure 9 is designed to ensure the cleanliness of the air entering the device, thereby protecting the internal components and improving the purity of the moxibustion.

[0057] By incorporating a filter structure 9 at the air inlet 2, this application effectively prevents impurities such as dust, hair, and fine particulate matter from entering the handheld moxibustion device. This not only significantly extends the service life of precision components such as the fan 4 and reduces the risk of malfunctions due to impurity accumulation, but also ensures that the air required for moxibustion combustion is clean and pollution-free. Consequently, the heat and volatile substances generated by the burning moxa stick can act more purely on the area to be treated, avoiding the adverse effects that may result from the mixing of impurities and moxa smoke, thereby improving the overall effect of moxibustion and the user experience.

[0058] This application further proposes that the above-mentioned filter structure 9 includes: a second filter screen 91 detachably installed outside the air inlet 2; a first filter screen 92 covering the second filter screen 91; and a honeycomb support frame 93 disposed inside the housing 1 and located on the air inlet side of the fan 4.

[0059] The first filter screen 92 is the filter medium covering the second filter screen 91. Its main function is to act as a primary filter layer to intercept larger particles in the air, such as hair, fibers, and large dust particles. The material of the first filter screen 92 can be non-woven fabric, polyester fiber mesh, coarse metal mesh, etc., with a relatively large pore size or mesh count to ensure low air resistance and effectively capture coarse impurities, thereby reducing the burden on subsequent filter layers.

[0060] Through the above technical solution, the filter structure 9 is designed as a filter layer consisting of a detachable second filter 91 and a first filter 92, achieving step-by-step filtration of the air entering the air inlet 2. Simultaneously, the first filter 92 effectively intercepts most large impurities, reducing the filtration burden on the internal second filter 91.

[0061] This application further proposes a method for performing moxibustion using the above-mentioned handheld moxibustion device, the steps of which include: placing the moxa stick in the storage part 5 and igniting it; starting the fan 4 to generate an airflow from the air outlet 3; and aligning the air outlet 3 with the area to be treated, so that the airflow delivers the heat and volatile substances generated by the burning moxa stick to the area to be treated.

[0062] Specifically, first, the moxa stick is placed inside the storage compartment 5 and ignited. The moxa stick is typically a cylindrical or conical moxa wool product, and its size should match the internal space of the storage compartment 5 to ensure stable placement and complete combustion. Placing the moxa stick inside the storage compartment 5 is a fundamental step in the moxibustion process, ensuring that the moxa stick burns in its predetermined position inside the device. Igniting the moxa stick can be done using an external fire source (such as a lighter or match), ensuring that the tip of the moxa stick burns completely and produces stable smoke and heat. This step lays the foundation for the subsequent airflow to carry the effective components of moxibustion.

[0063] Next, the fan 4 is activated to generate airflow from the outlet 3. The fan 4 is the core power component of the device, and its activation creates a forced convection system inside the device. When the fan 4 is working, it drives external air from the inlet 2 into the outer casing 1 and finally out through the outlet 3, forming a continuous airflow. This airflow not only provides the necessary oxygen for the combustion of the moxa sticks (through the third chamber 8), but more importantly, it acts as a carrier, carrying away and directionally transporting the heat generated by the combustion of the moxa sticks and pharmacologically active volatile substances (such as mugwort essential oil, moxa smoke particles, etc.) from the storage section 5.

[0064] Finally, the air outlet 3 is aimed at the area to be treated, allowing the airflow to deliver the heat and volatile substances generated by the burning moxa stick to the area. This step is crucial for achieving moxibustion treatment. The user holds the device and precisely aims the air outlet 3 at the body part requiring moxibustion. Because the airflow generated by the fan 4 is directional, the heat and volatile substances generated by the burning moxa stick are directed directly to the target skin area in a controllable manner. This directional delivery method ensures that the effective components of moxibustion can concentrate on the lesion or acupoint, avoiding the problems of smoke and heat loss associated with traditional moxibustion, while improving the accuracy and safety of moxibustion.

[0065] The air guide shroud 10 is equipped with a heating wire 11, which has a continuous wave-shaped structure. When the airflow passes through the air guide shroud 10, the wave-shaped heating wire 11 can effectively heat up the airflow and distribute its velocity, sort and regulate the airflow, weaken or eliminate eddies, turbulence and uneven velocity in the airflow, and ensure that the airflow achieves a more uniform and stable air outlet state before leaving the air outlet 3.

[0066] Meanwhile, a magnet 12 is installed on the housing 51. The magnetic attraction of the magnet 12 can be used to quickly attract and fix the protective cover 52, so that the protective cover 52 can be firmly assembled on the housing 51 in a detachable magnetic way, which not only ensures a reliable assembly, but also facilitates subsequent disassembly, maintenance and replacement.

[0067] An infrared light curtain generator 13 is installed at the air outlet 3. The airflow from the air outlet 3 is heated by the infrared light curtain generator 13 to form a hot air curtain that acts on the area to be treated with moxibustion.

[0068] The following specific example further illustrates the above technical solution: User A needs to perform moxibustion on a specific part of their body. User A can hold this moxibustion device, whose outer shell 1 has an interconnected air inlet 2 and an air outlet 3. User A first places the moxa stick in the storage section 5 of the device and lights it. The storage section 5 is located at the air outlet 3, and its inner shell 51 forms a space to hold the moxa stick. To prevent moxa ash from falling and to avoid burns caused by direct contact between the burning moxa stick and the skin, a protective cover 52 is detachably installed at the opening of the storage section 5.

[0069] After the moxa stick is lit, user A starts the fan 4 inside the device. Fan 4 begins operating, driving outside air into the device through the air inlet 2. To ensure the cleanliness of the incoming air, a filter structure 9 is installed at the air inlet 2. This filter structure 9 includes a second filter 91 detachably mounted on the outside of the air inlet 2, a first filter 92 covering the second filter 91, and a honeycomb support frame 93 located inside the outer casing 1 on the air inlet side of the fan 4. The first filter 92 has a smaller mesh size than the second filter 91, achieving step-by-step filtration of the incoming air, effectively blocking dust and impurities from entering the device, protecting the fan 4 and other internal components, and ensuring the cleanliness of the output airflow.

[0070] The air entering the device is driven by the fan 4, forming a directional airflow. This airflow's path within the device is carefully designed. The housing 1 contains a first chamber 6 connected to the air outlet 3, and a second chamber 7 for housing the control circuit board. A portion of the air entering the air inlet 2 is directed into the second chamber 7 to dissipate heat from the internal control circuit board, ensuring stable long-term operation and preventing performance or lifespan issues due to overheating. The cooled air then flows back into the first chamber 6.

[0071] Meanwhile, the outer shell 1 also contains a third chamber 8, which communicates with the first chamber 6 and the storage section 5. Air entering the third chamber 8 from the first chamber 6 is precisely guided to the moxa stick within the storage section 5 to supply oxygen for combustion. The storage section 5 has ventilation holes on its side wall or bottom that communicate with the third chamber 8, ensuring the moxa stick receives sufficient oxygen and thus guaranteeing continuous and stable combustion. This avoids the problem of traditional moxibustion boxes extinguishing midway due to insufficient oxygen supply in a confined space.

[0072] A flow guide hood 10 is also provided in the first chamber 6. The function of the flow guide hood 10 is to ensure that the airflow from the air outlet 3 is evenly distributed, avoiding the airflow from concentrating at a certain point or being unevenly distributed, thereby ensuring the stability and consistency of the moxibustion effect. In addition, the storage part 5 is located in the center of the air outlet 3, which further ensures that the airflow can cover the area to be treated with moxibustion with the heat and volatile substances generated by the burning moxa stick.

[0073] When user A aligns the air outlet 3 with the area to be treated, the forced airflow generated by the fan 4 precisely and efficiently delivers the heat and volatile substances (i.e., the effective components in the moxa smoke) generated by the burning moxa stick to the area. Compared to traditional moxibustion where heat and effective smoke substances diffuse randomly and have low utilization rates, this device significantly improves the utilization efficiency of heat energy and moxa materials through the directional delivery of forced airflow. Simultaneously, compared to moxibustion boxes that rely on natural heat convection, resulting in weak heat penetration and uneven distribution, this device enhances heat penetration through the forced airflow generated by the fan 4. Combined with the central design of the air guide shroud 10 and the storage section 5, it achieves uniform distribution of heat and volatile substances, thereby improving the therapeutic effect of moxibustion. Throughout the process, the protective cover 52 effectively prevents moxa ash from falling, eliminating the safety hazard of burns from moxa ash in traditional moxibustion and improving the safety of moxibustion operation.
