Moxibustion device

Abstract

This utility model relates to a moxibustion device, specifically in the field of moxibustion equipment technology. It includes a moxibustion chamber body, which comprises a fixed chamber, an adjustable chamber, and a mounting cover. The fixed chamber has a threaded groove on its side wall, and the adjustable chamber is threaded into the groove and can be raised and lowered, causing the mounting cover located above the adjustable chamber to rise and fall synchronously. Adjusting the distance between the moxa stick and the skin within the mounting cover achieves temperature control. The fixed chamber has a first annular vent on its side wall, and the adjustable chamber has a second annular vent at a corresponding position on its side wall. When the adjustable chamber rises along the threaded groove, the overlapping area of ​​the two vents decreases accordingly, reducing the oxygen intake within the moxibustion chamber body, slowing the burning speed of the moxa stick, and simultaneously lowering the temperature inside the chamber. This utility model, through an integrated design of threaded lifting and lowering combined with the linkage of the two annular vents, enables a single-step operation to simultaneously complete the adjustment of the moxa stick and the skin, as well as the adjustment of the oxygen intake within the moxibustion chamber. This solves the problems of traditional moxibustion boxes requiring two independent operations for temperature adjustment, resulting in low efficiency and poor temperature control accuracy.

Description

Technical Field

[0001] This application relates to the field of moxibustion equipment technology, and more particularly to a moxibustion device. Background Technology

[0002] The moxibustion device is a modern and standardized nursing instrument developed based on traditional Chinese medicine moxibustion, with moxibustion as its core and including derivative techniques such as indirect moxibustion and warm moxibustion. It is a portable, safe, and intelligent upgrade of traditional moxibustion operation. It is mainly used in clinical nursing, rehabilitation therapy, and home health care scenarios. By standardizing the application position, temperature, and duration of moxibustion, it achieves the therapeutic effects of traditional Chinese medicine moxibustion and solves the pain points of traditional handheld moxibustion, such as easy burns, cumbersome operation, and difficulty in temperature control.

[0003] Existing moxibustion boxes rely on two core temperature control methods: adjusting the distance between the moxa stick and the skin, and adjusting the temperature through ventilation to regulate oxygen intake in the moxibustion chamber. These are two completely independent operations, and each operation has a low single-time temperature adjustment threshold and limited temperature range. In actual use, if the temperature still does not meet the requirements after adjusting the temperature, the user needs to perform a separate ventilation adjustment. However, the temperature change range of a single ventilation adjustment is still limited, making precise calibration impossible. Often, repeated and alternating fine-tuning of both operations is required to gradually approach the target temperature, ultimately forming a repetitive cycle of "adjustment → temperature test → oxygen intake adjustment → temperature test → further adjustment / re-adjustment," with the problem of frequent hand lifting being particularly prominent.

[0004] Especially in scenarios where a single person uses the device independently, such as when treating the waist, abdomen, shoulders, and neck at home, the repeated alternating adjustments not only significantly reduce the efficiency of temperature control, but also prevent the user from balancing the comfort of the body with precise temperature control. Furthermore, the temperature adjustment effects of the two independent operations are not synergistic, making it difficult to achieve the ideal temperature in one step, further exacerbating the cumbersome operation and seriously violating the core user requirements of portability and convenience for moxibustion boxes.

[0005] Therefore, it is necessary to propose a moxibustion device to solve the above problems. Utility Model Content

[0006] This application provides a moxibustion device to improve the technical problems of existing moxibustion boxes in the related technology, such as the separate two-step operation of temperature adjustment and oxygen supply temperature adjustment, the low threshold of single adjustment, the need for repeated alternating fine adjustment, the cumbersome operation by a single person, and the inability to take into account both comfort and precise temperature control.

[0007] This application provides a moxibustion device, including a moxibustion chamber body, which consists of a fixed chamber, an adjustable chamber, and a mounting cover. The fixed chamber has a threaded groove on its side wall, and the adjustable chamber is threadedly engaged with the threaded groove and can be raised and lowered, thereby driving the mounting cover located above the adjustable chamber to rise and fall synchronously, thereby adjusting the distance between the moxibustion and the skin inside the mounting cover to achieve temperature control. The fixed chamber has a first annular vent on its side wall, and the adjustable chamber has a second annular vent at the corresponding position on its side wall. When the adjustable chamber rises along the threaded groove, the overlapping area of ​​the two vents decreases accordingly, which can reduce the amount of oxygen entering the moxibustion chamber and slow down the burning speed of the moxibustion, thereby achieving a synchronous reduction in the temperature inside the chamber.

[0008] The technical solutions described above in this application embodiment have at least the following technical effects: This moxibustion device, through an integrated structural design of threaded lifting and double-ring ventilation ports, enables single-step operation to simultaneously adjust the distance between the moxibustion device and the skin, as well as the oxygen supply to the moxibustion chamber. This effectively solves the technical problems of traditional moxibustion boxes requiring two independent operations for temperature adjustment, resulting in low efficiency and poor temperature control accuracy. The device has a compact overall structure, stable adjustment, and simple operation. It can accurately and efficiently control the temperature of the moxibustion chamber, avoiding burns and ensuring therapeutic effects. At the same time, the split chamber design facilitates assembly and maintenance, adapting to the needs of portable moxibustion, and greatly improving the practicality and user experience of the device.

[0009] In this embodiment, the bottom of the fixed chamber is provided with an annular groove, and the threaded groove is provided in the annular groove. The adjusting chamber is raised and lowered by the threaded groove, and its highest height is the height of the annular groove. This facilitates the separation between the adjusting chamber and the fixed chamber during the adjustment process. When the adjusting chamber is adjusted to the highest height, the part of the upper end of the first annular vent that does not overlap with the second annular vent is in contact with the side wall of the fixed chamber, which prevents air leakage from the top of the fixed chamber and the first annular vent.

[0010] This technical solution, through the structural design of the circular groove stroke limit and the sealing of the ventilation port, achieves the dual effects of preventing the adjustment chamber from falling off during lifting and the moxibustion chamber from leaking additional air. It not only eliminates device failure caused by component separation, but also ensures that the oxygen intake is regulated only by the overlapping area of ​​the double-ring ventilation ports. This structure is deeply integrated with the original threaded lifting and double-ring ventilation port linkage temperature control structure, further improving the stability of the device's lifting and adjustment and the accuracy of oxygen and temperature control. It avoids the risk of temperature control failure and component falling off, significantly enhancing the device's reliability and operational safety, and making the overall linkage effect of temperature control and distance adjustment more precise and closed-loop.

[0011] In this embodiment, both the first annular vent and the second annular vent are provided with protective nets.

[0012] This technical solution, by adding a protective net to the double-ring ventilation openings, achieves the effect of preventing foreign objects from entering without affecting the core functions of ventilation and oxygen regulation, thus maintaining cleanliness and ensuring the stability of moxibustion combustion. This structure works in deep collaboration with the original linkage temperature regulation, travel limit, and sealed oxygen control structures of the device, improving the safety protection system without changing the overall structural layout and core functions, enhancing the operational safety and reliability of the device, and further adapting to the portable use needs of portable moxibustion devices.

[0013] In this embodiment, a fixing pin is provided inside the mounting cover to facilitate the insertion and fixing of the moxibustion device onto the fixing pin.

[0014] This technical solution utilizes a fixing pin within the mounting cover to achieve convenient insertion and stable fixation of the moxibustion device, effectively preventing displacement and tipping. This structure works in tandem with the lifting mechanism of the mounting cover to ensure a constant position of the moxibustion device during temperature adjustment, improving the accuracy of temperature control by spacing. It also reduces the risk of burns and abnormal combustion caused by moxibustion displacement, simplifies the assembly and disassembly process, and optimizes the ease of use and combustion stability of the device without interfering with the core temperature control and ventilation functions of the moxibustion chamber. This further enhances the adaptability and safety of portable moxibustion devices in practical applications.

[0015] In this embodiment, an ash-blocking net is also provided inside the regulating chamber to catch the ash and prevent it from falling.

[0016] This technical solution, by adding an ash-blocking net inside the regulating chamber, achieves precise ash collection and prevents ash from falling, effectively avoiding ash burns and pollution problems. It works in synergy with the double ventilation protective net, threaded lifting, and precise temperature control structures to improve the safety protection system without interfering with the core functions and overall layout, enhancing the safety and cleanliness of use, and further strengthening the practical adaptability and reliability of the portable moxibustion device.

[0017] In this embodiment, a connecting truncated cone is also fixedly provided at the bottom of the fixed compartment, and the elastic bandage is detachably assembled to the connecting truncated cone to realize convenient replacement and adaptation of the elastic bandage.

[0018] Through this technical solution, the device utilizes a design that combines a fixed chamber with a detachable elastic bandage at the bottom, enabling convenient installation, removal, replacement, and stable assembly of the bandage. This adapts to various body parts and meets subsequent maintenance needs. The external design of this structure does not interfere with the core temperature control, protection, and adjustment functions of the moxibustion chamber, while also improving the fit and fixation of the device to the human body. Assembly and fixation can be completed by a single person, further enhancing the device's portability, adaptability, and operability, thus meeting the needs of portable moxibustion.

[0019] Beneficial Effects: This moxibustion device achieves single-step linkage and synergistic effects of temperature adjustment and oxygen intake through structural innovation. It fundamentally reconstructs the temperature adjustment method of existing moxibustion boxes in terms of operational logic and temperature control, completely solving the core problems of low adjustment thresholds, frequent operation, and inability to balance comfort and precise temperature control in existing technologies. It balances temperature control accuracy, ease of operation, safety, and scenario adaptability. The core beneficial effects are as follows: The innovative operating logic enables a simplified, single-step temperature control: breaking away from the existing two-step operation mode of lifting and oxygen intake temperature control, the two temperature control methods are integrated into a single-step lifting operation of the regulating chamber through the precise cooperation of the threaded groove and the double-ring ventilation port. This achieves "one-step operation, dual temperature control". The operating logic is simplified from the existing technology's repeated cycle of "lifting → temperature test → oxygen intake → temperature test → readjustment" to a simplified mode of "single-step lifting adjustment → one temperature test". This is fundamentally different from the existing independent operation mode, greatly reducing the complexity of operation and completely solving the pain point of frequent hand lifting operation. The dual temperature regulation effect is superimposed, greatly improving the single adjustment range: Through the linkage triggering design of lifting and lowering and oxygen intake temperature regulation, the two temperature regulation effects are positively superimposed. The lifting action simultaneously achieves "physical basic cooling + combustion-assisted cooling", and the lowering action simultaneously achieves "physical basic heating + combustion-assisted heating". The temperature adjustment threshold of a single lifting and lowering operation is significantly improved compared with the single operation of the existing technology. The adjustment effect is more intuitive and obvious. Users only need 1-2 single-step lifting and lowering operations to accurately reach the target temperature without repeated alternating fine adjustments. This fundamentally solves the core problems of "low single adjustment range and low temperature control efficiency" of the existing technology.

[0020] Precise temperature control combined with a comfortable user experience, perfectly suited for portable use: The sealed design ensures that the oxygen intake of the moxibustion chamber is regulated solely by the overlapping area of ​​the double-ring ventilation openings, making the linkage between oxygen intake temperature regulation and temperature adjustment more precise, and the combined effect of dual temperature regulation more controllable; The extremely simple operation method eliminates the need for users to frequently raise their hands to adjust the temperature, achieving precise temperature control while ensuring a comfortable experience for the body, perfectly meeting the needs of portable moxibustion in clinical care, home health care, and other scenarios, truly achieving the triple effect of "convenient operation + precise temperature control + comfortable experience".

[0021] With a stable structure and comprehensive protection, the device enhances safety and reliability: the circular groove's stroke limit design prevents the adjustment chamber from falling off, and the vent's sealing design ensures precise oxygen intake, improving the device's structural stability and temperature controllability; the ash barrier and vent protection net form a double safety protection, effectively avoiding problems such as ash burns and foreign object entry; the fixed needle securely positions the moxibustion, preventing temperature control failure and localized high-temperature burns caused by displacement. Without interfering with the core temperature control function, the device's safety protection system is perfected, significantly improving its safety and reliability. Attached Figure Description

[0024] Existing moxibustion boxes rely on two core temperature control methods: adjusting the distance between the moxa stick and the skin, and adjusting the temperature through ventilation to regulate oxygen intake in the moxibustion chamber. These are two completely independent operations, and each operation has a low single-time temperature adjustment threshold and limited temperature range. In actual use, if the temperature still does not meet the requirements after adjusting the temperature, the user needs to perform a separate ventilation adjustment. However, the temperature change range of a single ventilation adjustment is still limited, making precise calibration impossible. Often, repeated and alternating fine-tuning of both operations is required to gradually approach the target temperature, ultimately forming a repetitive cycle of "adjustment → temperature test → oxygen intake adjustment → temperature test → further adjustment / re-adjustment," with the problem of frequent hand lifting being particularly prominent.

[0025] Especially in scenarios where a single person uses the device independently, such as when treating the waist, abdomen, shoulders, and neck at home, the repeated alternating adjustments not only significantly reduce the efficiency of temperature control, but also prevent the user from balancing the comfort of the body with precise temperature control. Furthermore, the temperature adjustment effects of the two independent operations are not synergistic, making it difficult to achieve the ideal temperature in one step, further exacerbating the cumbersome operation and seriously violating the core user requirements of portability and convenience for moxibustion boxes.

[0026] Based on this, in order to improve the technical problems of existing moxibustion boxes in related technologies, such as the separate two-step operation of temperature adjustment and oxygen intake temperature adjustment, the low threshold of single adjustment, the need for repeated alternating fine adjustments, the cumbersome operation by a single person, and the inability to balance comfort and precise temperature control, the embodiments of this application provide the following solutions.

[0027] Please refer to the following: Figures 1 to 3This application provides a moxibustion device, which includes a moxibustion chamber body 1. The moxibustion chamber body 1 is composed of a fixed chamber 11, an adjustable chamber 12 and a mounting cover 13. The fixed chamber 11 has a threaded groove 111 on its side wall. The adjustable chamber 12 is threadedly engaged with the threaded groove 111 and can be raised and lowered, thereby driving the mounting cover 13 located above the adjustable chamber 12 to rise and fall synchronously, thereby adjusting the distance between the moxibustion and the skin inside the mounting cover 13 to achieve temperature control. The fixed chamber 11 has a first annular vent 113 on its side wall, and the adjustable chamber 12 has a second annular vent 121 on its corresponding side wall. When the adjustable chamber 12 rises along the threaded groove 111, the overlapping area of ​​the two vents is adjusted downwards, which can reduce the amount of oxygen entering the moxibustion chamber 1, slow down the burning speed of moxibustion, and achieve a synchronous reduction in the temperature inside the chamber.

[0028] The moxibustion device provided in this application embodiment, through the precise structural cooperation between the threaded groove 111 and the double annular vents, allows the temperature adjustment and oxygen supply temperature adjustment to be linked and superimposed through the single-step lifting and lowering operation of the adjustment chamber 12: When the adjustment chamber 12 rises, it simultaneously increases the distance between the moxibustion and the skin (physical cooling), while the overlapping area of ​​the double annular vents decreases, reducing the oxygen supply to the moxibustion chamber and slowing down the burning speed of the moxibustion (combustion-assisted cooling). The superposition of the two cooling effects significantly increases the cooling range of a single lifting operation; When the adjustment chamber 12 falls, it simultaneously decreases the distance between the moxibustion and the skin (physical heating), while the overlapping area of ​​the double annular vents increases, increasing the oxygen supply to the moxibustion chamber and accelerating the burning speed of the moxibustion (combustion-assisted heating). The superposition of the two heating effects significantly increases the heating range of a single falling operation.

[0029] This interconnected temperature control method reconstructs the temperature control operation logic from the existing technology's "multi-step alternating cycle" to "single-step lifting and lowering adjustment → one temperature test". Users only need to perform 1-2 single-step lifting and lowering operations based on their body sensation to achieve precise temperature control. There is no need to repeatedly alternate lifting and lowering operations with oxygen intake temperature control, completely eliminating the operation cycle of repeated temperature tests and frequent hand lifting. While improving temperature control efficiency, it also takes into account the body's comfort experience.

[0030] In this embodiment, a circular groove 112 is provided at the bottom of the fixed chamber 11, and a threaded groove 111 is provided in the circular groove 112. The adjusting chamber 12 is raised and lowered by the threaded groove 111, and its highest height is the height of the circular groove 112. This facilitates the separation between the adjusting chamber 12 and the fixed chamber 11 during the adjustment process. When the adjusting chamber 12 is adjusted to the highest height, the part of the upper end of the first annular vent 113 that does not overlap with the second annular vent 121 is in contact with the side wall of the fixed chamber 11, so as to avoid air leakage from the top of the fixed chamber 11 and the first annular vent 113.

[0031] This design allows for deep integration with the device's original threaded lifting and dual-ring ventilation temperature control structure: the design of the circular groove 112 embedded within the threaded groove 111 integrates the lifting and adjustment structure into the fixed chamber 11, making the overall structure of the moxibustion chamber 1 more compact. The stroke limit and threaded lifting work together to ensure smooth lifting and lowering of the adjustment chamber 12 while preventing component separation, thus enhancing the structural stability of the device. The ventilation port sealing feature and the dual-ring ventilation oxygen control structure form a closed loop, eliminating additional leakage channels. The oxygen intake of the moxibustion chamber is entirely determined by the overlapping area of ​​the two ventilation ports, making the spacing temperature adjustment and oxygen intake temperature control effects achieved by the threaded lifting more precise, avoiding temperature control failure caused by leakage, and making the linkage logic of single-step adjustment more rigorous. The overall structural fit and functional reliability are greatly improved.

[0032] In this embodiment, protective nets 14 are provided on both the first annular vent 113 and the second annular vent 121.

[0033] This design ensures high compatibility with the dual-ring ventilation system's oxygen regulation mechanism. The protective net 14 follows the ring design of the ventilation opening, achieving a high degree of fit with the ventilation opening structure. It does not alter the original oxygen intake path or the logic of oxygen regulation based on overlapping area, nor does it interfere with the temperature control effect of the screw lifting mechanism that drives the ventilation opening. Simultaneously, it forms a comprehensive safety protection system with the device's original anti-scalding features through spacing, dual temperature regulation of oxygen intake, anti-fall-off mechanisms, and sealed oxygen control structures. This system supplements the safety protection and combustion assurance at the ventilation opening on the basis of the original precise temperature control and structural stability. Furthermore, the protective net 14 is directly mounted on the ventilation opening, eliminating the need for additional space in the moxibustion chamber. This maintains the compact overall structure of the moxibustion chamber body 1, does not affect the screw lifting action of the regulating chamber 12, and exhibits strong synergy with the overall assembly structure.

[0034] In this embodiment, a fixing pin 131 is provided inside the mounting cover 13 to facilitate the insertion and fixing of the moxibustion device onto the fixing pin 131.

[0035] This design ensures that the structure of the mounting cover 13, which rises and falls synchronously with the adjustment chamber 12, is highly coordinated. The moxibustion device, through the fixing needle 131, forms an integrated structure with the mounting cover 13, rising and falling synchronously with the mounting cover 13. This ensures that the position of the moxibustion device remains constant when adjusting the distance between the moxibustion device and the skin, preventing the temperature adjustment from failing due to the displacement of the moxibustion device and improving the accuracy of temperature control. At the same time, the fixing needle 131 is built into the mounting cover 13, with a compact layout that does not occupy extra space in the moxibustion chamber, does not block the oxygen intake path of the ventilation vent, and does not interfere with the normal combustion of the moxibustion device and the adjustment of the oxygen content in the chamber. It works smoothly with the core structures such as the double-ring ventilation vent and the threaded lifting mechanism, further improving the functional layout of the main body 1 of the moxibustion chamber and making the functions of each structure of the device more coordinated.

[0036] In this embodiment, an ash-blocking net 2 is also provided inside the regulating chamber 12 to catch the ash and prevent it from falling.

[0037] This design allows the feature to work seamlessly with the existing structure of the device, preventing fine moxa ash from leaking out of the vents or the bottom of the chamber. It is fixed inside the fixed chamber 11, without occupying the lifting space of the adjusting chamber 12, without interfering with the threaded lifting of the adjusting chamber 12 and the synchronous adjustment of the mounting cover 13, and without affecting the oxygen regulation logic of the overlapping area of ​​the double-ring vents. It precisely corresponds to the moxa stick positioned by the fixing needle 131 inside the mounting cover 13, efficiently collecting the ash after burning. It is highly compatible with the overall temperature control, adjustment, and protection structure, without disrupting the compact layout of the moxibustion chamber, thus enhancing the functional synergy of the device.

[0038] In this embodiment, a connecting frustum 3 is also fixedly provided at the bottom of the fixed compartment 11, and the elastic bandage 4 is detachably assembled at the connecting frustum 3 to realize convenient replacement and adaptation installation of the elastic bandage 4.

[0039] With this configuration, the structure of this feature is highly compatible with the main body 1 of the moxibustion chamber. The connecting truncated cone 3 is fixed to the bottom of the fixed chamber 11. It is an external design that does not occupy the internal space of the chamber and does not interfere with the layout and function of the core structures such as the internal moxa ash barrier 2, the threaded lifting mechanism, and the ventilation opening. It does not affect the core functions of temperature control, anti-scalding, and oxygen adjustment within the chamber. The detachable elastic bandage 4 forms a flexible and adaptable fixed structure with the device, allowing the device to stably fit multiple parts of the human body such as the neck, shoulders, waist, abdomen, and joints. Moreover, after the bandage is fixed, it does not affect the threaded lifting and temperature adjustment operation of the adjustment chamber 12, ensuring the coordinated realization of the device's adjustment and fixation functions. This improves the overall functional layout of the device's therapeutic adjustment and portable fixation.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
