Description

Technical Field

[0001] This invention relates to the field of moxibustion technology, and in particular to a moxibustion device. Background Technology

[0002] Moxibustion is a common traditional Chinese medicine therapy. During the procedure, one end of the moxa stick is lit and brought close to the corresponding acupoint on the patient's skin. The heat and volatile components produced by the burning stick act on the acupoints and skin to achieve therapeutic effects such as unblocking meridians and harmonizing qi and blood.

[0003] However, the existing moxibustion process has the following problems: 1. Throughout the process, medical personnel need to hold the moxa stick continuously, which not only increases the labor intensity of the operator but may also lead to positioning errors due to prolonged operation, affecting the therapeutic effect. 2. When the moxibustion time is long, a certain amount of moxa ash will accumulate at the burning end of the moxa stick. When the moxa ash accumulates to a certain amount, it is easy for it to fall onto the patient's skin, which may cause burns. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art and provide a moxibustion device.

[0005] The objective of this invention is achieved through the following technical solution: A moxibustion device includes a moxa stick, a bottom ring, an outer sleeve, and an inner sleeve. A support column is provided on the bottom ring, and an adhesive surface is provided on the lower side of the bottom ring. The outer sleeve is rotatably connected to the support column. An inner sleeve is provided inside the outer sleeve, and the moxa stick is installed in the inner sleeve. A driving device and a ash-collecting tray assembly are provided on the support column. A slider that can move up and down is provided on the driving device. An ash-shaking driving mechanism is provided between the slider and the inner sleeve, and an oscillating driving mechanism is provided between the slider and the ash-collecting tray assembly. When the slider moves within a first height range, the oscillating driving mechanism drives the ash-collecting tray assembly to oscillate between an avoidance state and an ash-collecting state. When the slider moves within a second height range, the ash-shaking driving mechanism drives the inner sleeve to oscillate back and forth to shake off the ash at the lower end of the moxa stick.

[0006] Preferably, the dust-shaking driving mechanism includes an extension body disposed on the outside of the inner sleeve, a plurality of strip-shaped protrusions disposed at one end of the extension body, and a protrusion disposed on the slider and cooperating with the protrusions; a tension spring is disposed between the outer sleeve and the support column; when the slider moves to the second height range, the protrusion on the slider contacts the protrusion on the extension body, and when the protrusion passes the protrusion, it drives the inner sleeve to swing back and forth in the vertical plane.

[0007] Preferably, the ash-receiving tray assembly includes a connecting sleeve, an ash-receiving tray, and a connecting rod disposed between the connecting sleeve and the ash-receiving tray. The connecting sleeve is rotatably fitted with the support column so that the ash-receiving tray assembly can swing between an avoidance state and an ash-receiving state. When the ash-receiving tray assembly is in the ash-receiving state, the ash-receiving tray is located directly below the moxibustion stick. The swing drive mechanism includes a transmission groove vertically disposed on the outside of the connecting sleeve. The transmission groove includes a first straight groove, an inclined groove, and a second straight groove from bottom to top. A sliding shaft is provided on the slider, with one sliding end extending into the transmission groove. When the slider moves to a first height range, the sliding shaft on the slider is located in the inclined groove of the transmission groove, and the movement of the sliding shaft drives the connecting sleeve to rotate. When the slider moves to a second height range, the sliding shaft on the slider is located in the second straight groove of the transmission groove.

[0008] Preferably, the support column is provided with a cylindrical section, and the connecting sleeve is fitted onto the cylindrical section of the support column.

[0009] Preferably, the support column is provided with a limiting top block for limiting the outer sleeve.

[0010] Preferably, the outer sleeve and the inner sleeve are slidably fitted together. The outer side of the inner sleeve is provided with a limiting body and an elastic contact component that contacts the inner wall of the outer sleeve. The outer sleeve is provided with a third through groove corresponding to the limiting body, through which the limiting body passes. An upper limit screw and a lower limit screw are respectively provided at the upper and lower ends of the third through groove. The upper limit screw and the lower limit screw are used to limit the limiting body. When the slider is within the second height range and moves downward, the slider applies a downward force to the inner sleeve to make the inner sleeve move downward and make the limiting body on the inner sleeve contact the lower limit screw.

[0011] Preferably, the elastic contact component is an elastic sheet, one end of which is fixedly connected to the inner sleeve, and the other end of which contacts the inner wall of the outer sleeve.

[0012] Preferably, the outer sleeve is provided with a second through groove for the extension body to pass through.

[0013] Preferably, a gel patch is provided on the adhesive surface on the lower side of the bottom ring.

[0014] Preferably, the driving device is an electric linear module, and a control device is installed on the support column, with the electric linear module electrically connected to the control device.

[0015] The beneficial effects of this invention are: 1. When using this invention, the bottom ring is bonded to the patient's skin through the adhesive surface on the lower side, so that the entire moxibustion device is fixed in the corresponding position on the human body, while keeping the entire moxibustion device in an upright state; medical personnel do not need to hold the moxibustion strip throughout the process, freeing the operator's hands and greatly reducing labor intensity, which is especially suitable for long-term and multi-patient application scenarios.

[0016] 2. This invention enables automatic cleaning of moxa ash during moxibustion therapy, preventing the accumulation of ash that falls onto the patient's skin and effectively reducing the risk of burns from falling ash. Furthermore, the ash-collecting tray and the ash-shaking action work in tandem throughout the entire process, allowing for ash removal without interrupting the therapy. The removal is automatically completed by simply moving the slider via a drive device, ensuring the continuity of the entire moxibustion process and preventing interruptions due to ash removal, thus improving the patient experience.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] like Figures 1 to 7 As shown, a moxibustion device includes a moxa stick 1, a bottom ring 2, an outer sleeve 4, and an inner sleeve 10. A support column 3 is provided on the bottom ring 2, and an adhesive surface is provided on the lower side of the bottom ring 2. The outer sleeve 4 is rotatably connected to the support column 3. The inner sleeve 10 is provided inside the outer sleeve 4, and the moxa stick 1 is installed in the inner sleeve 10. A drive device 7 and an ash-collecting tray assembly 6 are provided on the support column 3. A slider 7-1 that can move up and down is provided on the drive device 7. A ash-shaking drive mechanism is provided between the slider 7-1 and the inner sleeve 10, and a swing drive mechanism is provided between the slider 7-1 and the ash-collecting tray assembly 6. When the slider 7-1 moves within a first height range, the swing drive mechanism drives the ash-collecting tray assembly 6 to swing between an avoidance state and an ash-collecting state. When the slider 7-1 moves within a second height range, the ash-shaking drive mechanism drives the inner sleeve 10 to swing back and forth to shake off the moxa ash at the lower end of the moxa stick 1.

[0029] In use, the bottom ring 2 is bonded to the patient's skin via its lower adhesive surface, fixing the entire moxibustion device in the corresponding position on the body and maintaining its vertical position. The moxibustion strip 1 is inserted into the inner sleeve 10, and its lower end is ignited, maintaining a certain distance between the lower end of the moxibustion strip 1 and the patient's skin. This invention achieves overall fixation of the moxibustion device to the patient's skin surface via the adhesive surface on the lower side of the bottom ring 2, eliminating the need for medical personnel to hold the moxibustion strip 1 throughout the process, freeing the operator's hands, significantly reducing labor intensity, and making it particularly suitable for long-term, multi-patient applications.

[0030] During prolonged moxibustion sessions (e.g., 5-6 minutes), the continuous burning of the lower end of the moxa stick 1 causes a certain amount of ash to accumulate. If the ash accumulates to a certain height and is not cleaned promptly, it can easily fall onto the patient's skin, posing a risk of burns. To address this problem, this invention automatically cleans the ash midway through the entire moxibustion treatment, thus preventing it from falling onto the patient's skin. The automatic cleaning of moxa ash is achieved in the following way: Before cleaning, the slider 7-1 on the drive device 7 is in the initial position at the lower end; during cleaning, the drive device 7 drives the slider 7-1 to move upward. During the upward movement, the slider 7-1 passes through the first height range and the second height range in sequence. When passing through the first height range, the swing drive mechanism drives the ash receiving tray assembly 6 to swing from the "avoidance state" to the "ash receiving state". At this time, the ash receiving tray assembly 6 is precisely located directly below the burning end of the moxa stick 1, and is used to catch the moxa ash that falls off the moxa stick 1. The slider 7-1 then moves upward to the second height range. When moving in the second height range, the ash shaking drive mechanism drives the inner sleeve 10 to swing back and forth, so that the moxa stick 1 swings synchronously with the inner sleeve 10, so that the moxa stick 1 forms a shaking effect. The moxa ash accumulated at the burning end of the moxa stick 1 falls off under the shaking action and falls exactly onto the ash receiving tray assembly 6 below. After the ash-shaking and ash-receiving processes are completed, slider 7-1 moves in the opposite direction and returns to the initial position. During the return process, slider 7-1 first passes through the second height range, then through the first height range, and finally reaches the initial position. When passing through the second height range in the opposite direction, the ash-receiving plate assembly 6 is swung back from the ash-receiving state to the open state by the swing drive mechanism, so that the ash-receiving plate assembly 6 is moved away from directly below the moxibustion stick 1, so as not to affect the heat conduction between the moxibustion stick 1 and the skin, and the moxibustion process can continue normally.

[0031] This invention enables automatic cleaning of moxa ash during moxibustion therapy, preventing the accumulation of ash that falls onto the patient's skin and effectively reducing the risk of burns from falling ash. Furthermore, the ash-collecting tray 6-2 works in conjunction with the ash-dispersing action throughout the process, allowing for ash removal without interrupting the therapy. The removal is automatically completed by moving the slider 7-1 via the drive device 7, ensuring the continuity of the moxibustion process and preventing interruptions due to ash removal, thus improving the patient experience.

[0032] In this invention, the swing drive mechanism and the dust-dissipating drive mechanism share the same power source of slider 7-1, and achieve coordinated action through height range division. Slider 7-1 first drives the dust receiving tray 6-2 to swing to the dust receiving position in the first height range, and then enters the second height range to start the inner sleeve 10 to dissipate dust. The whole process does not require additional power switching or adjustment of components, and the action is smoothly connected.

[0033] The outer sleeve 4 and the upper end of the support column 3 are connected by a hinge structure 5. The hinge structure 5 ensures that the outer sleeve 4 and the inner sleeve 10 can swing within a certain angle range, thus providing the basic conditions for the realization of the "ash shaking" function of the moxibustion stick 1.

[0034] The drive unit 7 is an electric linear module, and a control device 9 is installed on the support column 3. The electric linear module is electrically connected to the control device 9. The drive unit 7 can precisely drive the slider 7-1 to move. The drive unit 7 is electrically connected to the control device 9, which controls parameters such as the start time and movement stroke of the drive unit 7. The control device 9 has a built-in Bluetooth module, which can connect to the user's mobile phone app and set parameters through the app. For example, if the total duration of a moxibustion process is 6 minutes, and the ash needs to be cleaned 3 minutes after the moxibustion begins, the start time of the drive unit 7 can be set to "3 minutes". Then, 3 minutes after the start of the moxibustion, the drive unit 7 will automatically turn on and drive the slider 7-1 to move, thus initiating the ash cleaning process.

[0035] Specifically, the dust-shaking drive mechanism includes an extension body 10-3 disposed on the outside of the inner sleeve 10, several strip-shaped protrusions 10-3a disposed at one end of the extension body 10-3, and a protrusion 7-3 disposed on the slider 7-1 and cooperating with the protrusions 10-3a; a tension spring 8 is disposed between the outer sleeve 4 and the support column 3; when the slider 7-1 moves to the second height range, the protrusion 7-3 on the slider 7-1 contacts the protrusions 10-3a on the extension body 10-3, and the protrusion 7-3 drives the inner sleeve 10 to swing back and forth in the vertical plane when it passes the protrusions 10-3a.

[0036] The protrusions 10-3a are evenly spaced along the vertical direction, and the cross-section of the protrusions 10-3a is semi-circular. When slider 7-1 moves within the second height range, protrusion 7-3 moves up and down synchronously with slider 7-1, making direct contact with the protrusion and sliding relative to it. When protrusion 7-3 passes each protrusion 10-3a, it pushes the extension body 10-3 and applies a lateral thrust, which is directly transmitted to the inner sleeve 10, forming a swing driving force. At the same time, the tension spring 8 between the outer sleeve 4 and the support column 3 applies an elastic tension force to the extension body 10-3 in the direction of protrusion 7-3, realizing the elastic reset function. When protrusion 7-3 pushes the inner sleeve 10 to swing to one side, tension spring 8 is stretched to generate a reverse elastic tension force. When protrusion 7-3 disengages from the current protrusion 10-3a and the thrust disappears, the elastic tension force of tension spring 8 pulls the inner sleeve 10 to reset, preparing for the next contact between protrusion 7-3 and protrusion 10-3a. Finally, the back-and-forth swinging effect of the inner sleeve 10 and moxibustion stick 1 is achieved, thereby shaking off the moxa ash at the lower end of moxibustion stick 1.

[0037] The outer sleeve 4 is provided with a second through groove 4-1 for the extension body 10-3 to pass through, thereby ensuring that the extension body 10-3 can pass through the outer sleeve 4 and contact the protrusion 7-3 on the slider 7-1.

[0038] The slider 7-1 on the drive device 7 is located on the side of the support column 3 away from the outer sleeve 4. The support column 3 is provided with a first through groove 3-3 corresponding to the extension body 10-3, and the extension body 10-3 passes through the first through groove 3-3.

[0039] The support column 3 is provided with a limiting top block 3-1 for limiting the outer sleeve 4. When the protrusion 7-3 is not in contact with the protrusion, the outer sleeve 4 is pressed tightly against the limiting top block 3-1 under the action of the tension spring 8, so that the outer sleeve 4 is stably maintained in the current state.

[0040] The ash-receiving tray assembly 6 includes a connecting sleeve 6-1, an ash-receiving tray 6-2, and a connecting rod 6-3 disposed between the connecting sleeve 6-1 and the ash-receiving tray 6-2. The connecting sleeve 6-1 is rotatably fitted with the support column 3 so that the ash-receiving tray assembly 6 can swing between an avoidance state and an ash-receiving state. When the ash-receiving tray assembly 6 is in the ash-receiving state, the ash-receiving tray 6-2 is located directly below the moxibustion stick 1. The swing drive mechanism includes a transmission groove vertically disposed on the outside of the connecting sleeve 6-1, and the transmission groove is arranged from bottom to top as follows: It includes a first straight groove 6-1a, an inclined groove 6-1b, and a second straight groove 6-1c; a sliding shaft 7-2 is provided on the slider 7-1, with one sliding end extending into the transmission groove; when the slider 7-1 moves to the first height range, the sliding shaft 7-2 on the slider 7-1 is located in the inclined groove 6-1b of the transmission groove, and the movement of the sliding shaft 7-2 drives the connecting sleeve 6-1 to rotate; when the slider 7-1 moves to the second height range, the sliding shaft 7-2 on the slider 7-1 is located in the second straight groove 6-1c of the transmission groove.

[0041] The connecting sleeve 6-1 is fitted onto the support column 3 and forms a rotational fit, providing a stable fulcrum for the swing of the ash-receiving tray assembly 6, ensuring a smooth and uninterrupted swing process. When the ash-receiving tray assembly 6 switches to the ash-receiving state, the length design of the connecting rod 6-3 is precisely matched with the rotation angle, so that the ash-receiving tray 6-2 is exactly below the moxa stick 1, ensuring that it can completely catch the falling moxa ash.

[0042] The transmission groove consists of three sections: a first straight groove 6-1a, an inclined groove 6-1b, and a second straight groove 6-1c. The first straight groove 6-1a and the second straight groove 6-1c are both vertical along the vertical direction, and the inclined groove 6-1b connects the first straight groove 6-1a and the second straight groove 6-1c. When the sliding shaft 7-2 on the slider 7-1 moves in the first straight groove 6-1a and the second straight groove 6-1c, the arrangement direction of the first straight groove 6-1a and the second straight groove 6-1c is consistent with the moving direction of the sliding shaft 7-2, so the connecting sleeve 6-1 will not rotate. When the slider 7-1 moves in the first height range, the sliding shaft 7-2 slides along the inclined groove 6-1b. The inclination angle of the inclined groove 6-1b converts the vertical movement of the slider 7-1 into the rotational movement of the connecting sleeve 6-1, driving the ash receiving tray 6-2 to rotate between the avoidance state and the ash receiving state. When the slider 7-1 enters the second height range (ash shaking stage), the sliding shaft 7-2 enters the second straight groove 6-1c. At this time, the vertical movement of the slider 7-1 will not drive the connecting sleeve 6-1 to rotate, and the ash receiving tray 6-2 remains stationary in the ash receiving state, ensuring that all the shaken-off ash falls into the tray.

[0043] Among them, a cylindrical section 3-2 is provided on the support column 3, and the connecting sleeve 6-1 is sleeved on the cylindrical section 3-2 of the support column 3.

[0044] Furthermore, the outer sleeve 4 and the inner sleeve 10 are slidably fitted together. The outer side of the inner sleeve 10 is provided with a limiting body 10-1 and an elastic contact component that contacts the inner wall of the outer sleeve 4. The outer sleeve 4 is provided with a third through groove 4-2 corresponding to the limiting body 10-1, and the limiting body 10-1 passes through the third through groove 4-2. The upper and lower ends of the third through groove 4-2 are respectively provided with an upper limit screw 4-3 and a lower limit screw 4-4. The upper limit screw 4-3 and the lower limit screw 4-4 are used to limit the limiting body 10-1. When the slider 7-1 is within the second height range and moves downward, the slider 7-1 applies a downward force to the inner sleeve 10 to make the inner sleeve 10 move downward and make the limiting body 10-1 on the inner sleeve 10 contact the lower limit screw 4-4.

[0045] During the burning process, the length of the moxibustion stick 1 gradually shortens. If the inner sleeve 10 is fixed in position, the distance between the burning end of the moxibustion stick 1 and the skin will increase with the extension of the burning time, resulting in a weakening of the heating effect and a decrease in the therapeutic effect. In this invention, the structure of "slider 7-1 driving the inner sleeve 10 to move downward" achieves distance compensation of the moxibustion stick 1 while cleaning the moxa ash, thus improving the therapeutic effect in the later stage of the moxibustion process. When the slider 7-1 moves downward within the second height range, it applies a downward force to the inner sleeve, pushing the inner sleeve 10 down along the inner wall of the outer sleeve 4 until the limiting body 10-1 contacts the lower limiting screw 4-4. At this time, the burning end of the moxibustion stick 1 moves downward synchronously with the inner sleeve 10, which just makes up for the shortening of the length caused by the burning loss, and restores the distance between the burning end and the skin to the initial optimal range.

[0046] The distance compensation action and the ash cleaning action are driven by the same component (slider 7-1), without the need for additional control buttons or manual adjustment steps. Each time the ash is cleaned, the inner sleeve 10 is moved down synchronously by the downward movement of slider 7-1 to achieve distance compensation. This ensures that the distance between the burning end and the skin remains stable within a suitable range throughout the moxibustion process, avoiding the drawback of insufficient effect due to excessive distance between the burning end and the skin in the later stages of moxibustion, and ensuring the consistency and continuity of the effect throughout the entire moxibustion process.

[0047] By adjusting the upper limit screw 4-3 and the lower limit screw 4-4 together, the downward distance of the moxibustion stick 1 can be adjusted, thus adapting to moxibustion sticks 1 with different burning speeds.

[0048] The elastic contact component on the outer side of the inner sleeve 10 contacts the inner wall of the outer sleeve 4, and the static friction generated therefrom allows the inner sleeve 10 to stably maintain its current height when no other external force is applied. When the slider 7-1 is within the second height range and moves downward, the downward force exerted by the slider 7-1 on the inner sleeve 10 will be greater than the static friction generated by the elastic contact component, thereby causing the inner sleeve 10 to overcome the static friction generated by the elastic contact component and move downward.

[0049] The elastic contact component is an elastic sheet 10-2. One end of the elastic sheet 10-2 is fixedly connected to the inner sleeve 10, and the other end of the elastic sheet 10-2 contacts the inner wall of the outer sleeve 4. In this embodiment, the elastic sheet 10-2 is made of spring steel.

[0050] A gel patch is attached to the adhesive surface on the underside of the bottom ring 2. The gel patch adheres to the patient's skin. Both sides of the gel patch are adhesive. After each use, the gel patch can be peeled off the bottom ring 2 and replaced with a new one.

[0051] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
