Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine moxibustion equipment technology, specifically an adjustable distance self-sealing integrated electrothermal suspended moxibustion device. Background Technology

[0002] Traditional suspended moxibustion therapy requires the operator to hold the moxa stick at a certain distance from the patient's skin. However, existing techniques have the following drawbacks:

[0003] 1. Risk of burns to operators: The temperature rises sharply as the moxa stick burns to the end, making it easy to burn the operator if handled by hand, thus affecting the continuity of treatment. 2. Difficulty in extinguishing: Unburnt moxa sticks are difficult to extinguish completely, and discarding them directly poses a fire hazard and wastes resources. 3. Smoke pollution: The smoke produced during combustion can easily stain the operator's fingers, affecting the operating experience and hygiene.

[0004] Existing moxibustion devices mostly use fixed brackets or simple heat insulation structures, which cannot achieve the integrated operation of precise distance adjustment, portable ignition, and sealed oxygen-free preservation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adjustable distance self-sealing integrated electric heating suspended moxibustion device that is retractable, oxygen-blocking, and integrated with electric heating ignition, so as to improve safety, portability and efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] An adjustable distance self-sealing integrated electrothermal suspended moxibustion device includes a cylindrical moxibustion cylinder with an opening at one end and an end plate at the other end. The inner cavity of the moxibustion cylinder is provided with a moxa stick fixing seat, and the moxa stick is installed on the moxa stick fixing seat and faces the opening end of the moxibustion cylinder. It also includes a sealing cover that is detachably sleeved on the opening end of the moxibustion cylinder and a moxa stick telescopic adjustment mechanism arranged at the axial center of the moxibustion cylinder. The sealing cover integrates a rechargeable electrothermal ignition module. The moxa stick telescopic adjustment mechanism is connected to the moxa stick fixing seat to adjust its axial movement so that the moxa stick can extend or retract into the moxibustion cylinder. When extended, the burning end can contact the rechargeable electrothermal ignition module to ignite. When retracted, the sealing cover and the moxibustion cylinder form a sealing fit to isolate oxygen and extinguish the fire.

[0008] As a further improvement to the above technical solution:

[0009] Furthermore, the moxibustion cylinder is provided with a partition plate parallel to the end plate and having a central shaft hole. The moxa stick telescopic adjustment mechanism includes a spiral shaft passing through the partition plate and the end plate, and a rotating adjustment cover located outside the end plate. The spiral shaft is rotatably supported on the end plate and the partition plate by bearings. One end of the spiral shaft at the opening end of the moxibustion cylinder has an external thread section, and the other end outside the end plate has a hexagonal shaft section. The moxa stick fixing seat passes through the external thread section through a threaded through hole in the middle. An anti-rotation component is provided between the outer side of the moxa stick fixing seat and the side wall of the moxibustion cylinder to prevent the moxa stick fixing seat from rotating synchronously with the spiral shaft, and a limiting retaining ring is provided at the end of the external thread section. The rotating adjustment cover is detachably sleeved on the hexagonal shaft section through a hexagonal hole connection part set at the axial center of its inner side. When the rotating adjustment cover rotates, the inner side wall of its side wall contacts the outer periphery of the moxibustion cylinder.

[0010] Furthermore, the moxa stick fixing base includes a base plate and a sleeve. The base plate is parallel to the partition plate and is threadedly connected to the external thread section of the spiral shaft through a threaded hole at its center. The sleeve is vertically fixed to the middle of the side of the base plate away from the partition plate and sleeved on the outside of the spiral shaft. Its free end is provided with a fixing pin for fixing the moxa stick. The anti-rotation component includes axial guide ribs on both sides of the edge of the base plate and guide grooves at corresponding positions in the side wall of the moxibustion cylinder. When the spiral shaft rotates, the base plate slides through the guide ribs and guide grooves to convert the rotational motion into linear movement.

[0011] Furthermore, the moxibustion tube is made of high-temperature resistant alloy material, and its outer periphery is coated with a heat-insulating graphite coating with a thickness of 0.5-0.6 mm.

[0012] Furthermore, the rechargeable electric heating ignition module includes a ring-shaped resistance wire, a lithium battery, and a PCB board with integrated control circuitry. The resistance wire is mounted on the center of the top surface inside the sealed cover via a ceramic base. The lithium battery and the PCB board are both mounted inside the sealed cover. The side wall of the sealed cover is provided with a push-button switch, an LED indicator, and a USB interface electrically connected to the lithium battery. The resistance wire, lithium battery, push-button switch, and LED indicator are all electrically connected to the PCB board.

[0013] Furthermore, the control circuit includes an overheat protection chip and a temperature sensor. The overheat protection chip is connected in series in the power supply circuit of the resistance wire, and the temperature sensor is mounted on a ceramic base.

[0014] Furthermore, it also includes a dust-blocking plate that can be detachably fitted onto the opening end of the moxibustion cylinder.

[0015] Furthermore, the inner side of the opening end of the sealing cap is provided with a limiting countersunk hole, and the sealing cap is sleeved with the moxibustion cylinder through the limiting countersunk hole.

[0016] Furthermore, the outer surface of the rotating adjustment cover is provided with anti-slip texture.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The adjustable distance self-sealing integrated electrothermal suspended moxibustion device of this utility model, by setting up a moxa stick telescopic adjustment mechanism and a sealing cover, and integrating a rechargeable electrothermal ignition module on the sealing cover, combines the sealing oxygen cut-off technology with electrothermal ignition technology, and can realize the entire moxibustion process of "one tube integration". Not only does it not require an external fire source when igniting the moxa stick, and has a wide range of applications, it can also solve the problems of distance adjustment and burns in traditional hand-held operation, greatly improving safety and portability.

[0019] 2. The adjustment principle of the moxa stick extension and retraction adjustment mechanism of this utility model is similar to that of "adjusting the extension and retraction of a lipstick", which can realize stepless adjustment of the length of the moxa stick. It has a simple structure and is easy to operate.

[0020] 3. The device of this utility model has a graphite heat insulation coating on the outside of the moxibustion tube, which can significantly reduce heat transfer and avoid the risk of burns. Attached Figure Description

[0029] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1-6 As shown, the adjustable distance self-sealing integrated electrothermal suspended moxibustion device of this embodiment includes a cylindrical moxibustion cylinder 1 with an opening at one end and an end plate at the other end. The inner cavity of the moxibustion cylinder 1 is provided with a moxa stick fixing seat 2. The moxa stick 3 is installed on the moxa stick fixing seat 2 and faces the opening end of the moxibustion cylinder 1. It also includes a sealing cover 4 that is detachably sleeved on the opening end of the moxibustion cylinder 1 and a moxa stick telescopic adjustment mechanism 6 arranged at the axial center of the moxibustion cylinder 1. The sealing cover 4 integrates a rechargeable electrothermal ignition module 5. The moxa stick telescopic adjustment mechanism 6 is connected to the moxa stick fixing seat 2 to adjust its axial movement so that the moxa stick 3 can extend or retract into the moxibustion cylinder 1. When extended, the burning end can contact the rechargeable electrothermal ignition module 5 to ignite. When retracted, the sealing cover 4 and the moxibustion cylinder 1 form a sealing fit to isolate oxygen and extinguish. This utility model combines a moxa stick telescopic adjustment mechanism and a sealing cover, and integrates a rechargeable electric heating ignition module into the sealing cover. This combines the sealing and oxygen-blocking technology with the electric heating ignition technology, enabling a "one-tube integration" of the entire moxibustion process. Not only does it eliminate the need for an external fire source when igniting the moxa stick, making it widely applicable, but it also solves the problems of distance adjustment and burns associated with traditional handheld operation, greatly improving safety and portability.

[0031] In this embodiment, the moxibustion cylinder 1 has a partition plate 11 parallel to the end plate and with a central shaft hole inside. The moxa stick telescopic adjustment mechanism 6 includes a spiral shaft 61 passing through the partition plate 11 and the end plate, and a rotating adjustment cover 62 located outside the end plate. The spiral shaft 61 is rotatably supported on the end plate and the partition plate 11 by bearings. One end of the spiral shaft 61 at the open end of the moxibustion cylinder 1 has an external thread section, and the other end outside the end plate has a hexagonal shaft section. The moxa stick fixing seat 2 is connected to the external thread section through a threaded through hole in the middle. An anti-rotation component is provided between the outer side of the moxa stick fixing seat 2 and the side wall of the moxibustion cylinder 1 to prevent the moxa stick fixing seat 2 from rotating synchronously with the spiral shaft 61. A limiting retaining ring is provided at the end of the external thread section to prevent the moxa stick fixing seat 2 from moving excessively and falling off. The rotating adjustment cover 62 is detachably sleeved on the hexagonal shaft section through a hexagonal hole connection part set at the axial center of its inner side. The two can be connected by an transition fit and are not easy to fall off. When the rotating adjustment cover 62 rotates, its inner side wall contacts the outer periphery of the moxibustion cylinder 1. The rotation of the rotating adjustment cover 62 drives the spiral shaft 61 to rotate synchronously. The moxa stick fixing seat 2 cannot rotate due to the presence of the anti-rotation component; it only achieves axial movement through threaded transmission with the spiral shaft 61, allowing the moxa stick 3 to extend and retract from the moxibustion cylinder 1. The adjustment principle of this moxa stick extension and retraction adjustment mechanism is similar to "adjusting the extension and retraction of a lipstick," enabling stepless adjustment of the moxa stick length. It has a simple structure and is easy to operate.

[0032] In this embodiment, the moxa stick fixing base 2 includes a base plate 21 and a sleeve 22. The base plate 21 is parallel to the partition plate 11 and is threadedly connected to the external thread section of the spiral shaft 61 through a threaded hole at its center. The sleeve 22 is vertically fixed to the middle of the side of the base plate 21 away from the partition plate 11 and is sleeved on the outside of the spiral shaft 61. A certain gap is provided between the inner wall of the sleeve and the outer periphery of the limiting retaining ring provided on the external thread section of the spiral shaft 61. The free end of the sleeve 22 is provided with a fixing pin 23 for fixing the moxa stick 3. In this embodiment, the length of the external thread section on the spiral shaft 61 is preferably such that the end of the external thread section is located inside the sleeve 22 when the base plate 21 is furthest from the opening end of the moxibustion cylinder, so as not to interfere with it when the moxa stick retracts. The anti-rotation component includes axial guide ribs 24 located on both sides of the edge of the base plate 21 and guide grooves 12 located at corresponding positions within the side wall of the moxibustion cylinder 1. When the spiral shaft 61 rotates, the base plate 21 converts the rotational motion into linear movement through the sliding engagement of the corresponding guide ribs 24 and guide grooves 12. The guide ribs and guide grooves restrict the moxa stick fixing seat to move only along the axis and prevent it from rotating.

[0033] In this embodiment, the moxibustion cylinder 1 is made of a high-temperature resistant alloy material, and its outer side can be coated with a heat-insulating graphite coating 7 with a thickness of 0.5-0.6 mm. The graphite heat-insulating coating can significantly reduce heat transfer and avoid the risk of burns.

[0034] In this embodiment, a mesh-type ash-blocking sheet 8 is also included, which can be detachably fitted onto the open end of the moxibustion cylinder 1. The ash-blocking sheet (existing technology) can prevent moxa stick ash from falling onto the recipient during moxibustion, thus avoiding the risk of burns.

[0035] In this embodiment, a limiting countersunk hole is provided on the inner side of the opening end of the sealing cap 4, and the sealing cap 4 is sleeved with the moxibustion cylinder 1 through the limiting countersunk hole. This structure can limit the sleeve length between the sealing cap and the moxibustion cylinder, avoiding damage to the rechargeable electric heating ignition module.

[0036] In this embodiment, the outer surface of the rotating adjustment cover 62 is provided with anti-slip texture for easy adjustment and use.

[0037] In this embodiment, the rechargeable electrothermal ignition module 5 includes a ring-shaped resistance wire 51 (made of nickel-chromium alloy, preferably with a resistance of 2Ω), a lithium battery 52 (preferably 3.7V, 500mAh), and a PCB board 53 integrating a control circuit. The resistance wire 51 is mounted on the center of the top surface inside the sealing cover 4 via a ceramic base. The lithium battery 52 and the PCB board 53 are both mounted on the inner side wall of the sealing cover 4. A push-button switch, an LED indicator (not shown in the figure), and a micro USB interface 54 electrically connected to the lithium battery 52 are provided on the outer side wall of the sealing cover 4 (the outer side may also be covered with a high-temperature resistant silicone waterproof plug, not shown). The resistance wire 51, the lithium battery 52, the push-button switch, and the LED indicator are all electrically connected to the PCB board 53. The control circuit includes an overheat protection chip and a temperature sensor. The overheat protection chip is connected in series in the power supply circuit of the resistance wire 51 to monitor the temperature of the resistance wire in real time. If the temperature exceeds a set threshold (e.g., 1000℃), the current is automatically cut off. The temperature sensor is attached to the ceramic base and feeds back the temperature data to the control circuit to achieve dynamic regulation. When the lithium battery is connected to an external power source via a USB interface, the charging management module also controls the current input to prevent overcharging or short circuits. The details of the aforementioned resistor wire, lithium battery, overheat protection chip, charging management module, control circuit, PCB board, and their electrical connections can all be found in existing technologies and will not be elaborated upon here.

[0038] Working principle:

[0039] When igniting: Press the button switch → the control circuit is closed → the lithium battery current flows to the resistance wire through the control circuit → the resistance wire is heated to the ignition temperature → rotate the adjustment cover to drive the spiral shaft to rotate so that the moxa stick extends out of the moxibustion cylinder and contacts the resistance wire → ignite the moxa stick → release the button switch → the control circuit is disconnected → the resistance wire cools down and enters standby mode;

[0040] During moxibustion: retract the lit moxa stick into the moxibustion cylinder → attach the ash-blocking plate to the moxibustion cylinder → perform moxibustion → rotate the adjusting cover as needed to drive the spiral shaft to adjust the distance between the moxa stick and the ash-blocking plate.

[0041] When extinguishing: After moxibustion is completed → remove the dust cover → cover with the sealing cap to isolate oxygen → the moxa stick will extinguish.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
