Description

Technical Field

[0001] This invention relates to the field of moxibustion device technology, specifically to an intelligent moxibustion device with fireproof function. Background Technology

[0002] Moxibustion stimulates specific acupoints or areas of the body by burning mugwort (moxa sticks or moxa cones made from mugwort leaves) to warm and unblock the meridians, promote blood circulation, dispel cold and dampness, and prevent disease and maintain health.

[0003] When performing moxibustion, it is necessary to light the moxa and bring it close to the acupoints on the body. In order to avoid the inconvenience caused by holding the moxa for a long time, the existing technology often uses a special moxibustion box to fix the moxa stick (or moxa cone) in the moxibustion box and place the moxibustion box on the area that needs moxibustion.

[0004] When using the moxibustion box, light the moxa stick (or moxa cone), with the burning end of the moxa stick facing down and about 3-7 cm away from the body. There is a metal isolation mesh between the moxa stick and the body. The ash produced during the burning process falls downwards onto the isolation mesh and does not come into contact with the body, thus avoiding burns.

[0005] However, the falling ash may not be completely extinguished. Although the isolation net prevents it from falling onto human skin, it cannot extinguish it. If the unextinguished ash is carried out by the airflow, it will cause a fire. Therefore, the fire resistance of moxibustion boxes in the current technology needs to be further improved. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent moxibustion device with fire-resistant function. By using water droplets from the nozzle to keep the cotton gauze moist during moxibustion, the ash falling from the burning end of the moxa stick falls onto the cotton gauze, thereby wetting the ash and extinguishing any sparks that may be present, thus preventing burns or fires caused by unextinguished sparks in the ash.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an intelligent moxibustion device with fireproof function, comprising a box and two moxa sticks. The bottom of the box is arc-shaped to better fit the curve of the human body. The bottom of the moxa sticks is located inside the box. When in use, the bottom of the moxa sticks is lit. An isolation component is provided on the inner wall of the box.

[0008] The isolation component includes an iron isolation mesh fixed to the inner wall of the box, with cotton gauze at the top of the iron isolation mesh, the cotton gauze located at the bottom of the moxa stick, and a sponge block placed at the top of the cotton gauze.

[0009] A water storage box is fixedly installed on the front wall of the inner wall of the box, and multiple drip nozzles are fixedly installed at the bottom of the water storage box, with the drip nozzles located above the sponge block.

[0010] Furthermore, the water storage box has two water injection holes at the top, and each water injection hole is equipped with a rubber stopper. The sponge block has two elastic strips at the top, one end of which is connected to the inner wall of the box. The elastic strips use their own elasticity to clamp the sponge block, so that the sponge block fits against the cotton gauze.

[0011] Furthermore, the iron isolation net is provided with multiple fixing components, each including a rod that passes through the iron isolation net and the cotton gauze, with a magnet fixed at the top of the rod, the magnet being located at the top of the cotton gauze.

[0012] Furthermore, a temperature sensor is installed on the rear wall inside the box, a controller is provided on one side of the box, a Bluetooth module is provided on the front side of the box, the temperature sensor is located at the input end of the controller, the controller is wirelessly connected to a mobile phone via the Bluetooth module, and multiple ventilation slots for ventilation are provided on both sides of the box.

[0013] Furthermore, the top of the box is provided with a detachable cover plate, and the cover plate is provided with two mounting tubes that penetrate the cover plate. The tops of the two moxa sticks extend to the top of the mounting tubes through the two mounting tubes respectively.

[0014] Furthermore, an annular airbag is fixedly provided on the inner wall of the installation tube, and the annular airbag is sleeved on the outer end of the corresponding moxa stick. Two air storage tubes are provided on the rear side of the box, and the two air storage tubes correspond to the two installation tubes respectively.

[0015] The top end of the gas storage pipe is fixedly equipped with a gas delivery hose, the front end of which extends into the corresponding installation tube and is fixedly connected to the annular airbag. An adjustment plug is threadedly connected to the bottom opening of the gas storage pipe. Elastic clips are provided on both sides of the gas storage pipe and are fixed to the rear side of the box.

[0016] Furthermore, the bottom end of the installation tube is threaded with a sleeve, which is located inside the box. Multiple isolation strips made of ceramic are fixed on the inner wall of the sleeve, and the bottom end of the moxa stick extends into the sleeve and contacts the isolation strips.

[0017] Furthermore, the top of the moxa stick is provided with a counterweight assembly, which includes a U-shaped frame. Both ends of the U-shaped frame are fixed with arc-shaped pieces, which are respectively clamped on both sides of the moxa stick. The top of the U-shaped frame is provided with a counterweight block.

[0018] Furthermore, a column is provided on one side of the box body, a slide is fitted on the outer end of the column, an adjusting beam is provided on the front side of the slide, and one end of the adjusting beam is detachably connected to the box body;

[0019] An adjustment frame is fixedly provided on the front side of the slide block and sleeved on the outer end of the adjustment beam. A first fastening bolt is provided on the front side of the adjustment frame by thread. An installation frame is fixedly provided on the bottom end of the column, and two second fastening bolts are provided on the bottom end of the installation frame by thread.

[0020] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0021] 1. By laying a layer of cotton gauze on top of the iron isolation net and using the water droplets dripping from the nozzle to keep the cotton gauze moist during moxibustion, the ash falling from the burning end of the moxa stick falls onto the cotton gauze, thus wetting the ash and extinguishing any sparks that may be present. This prevents burns or fires caused by unextinguished sparks in the ash and effectively improves the fire resistance of the moxibustion device.

[0022] 2. By threading a sleeve onto the bottom of the installation tube, the moxa stick is vertically inserted into the sleeve through the installation tube. The burning end of the moxa stick is always in contact with the isolation strip, ensuring that the height of the burning ends of the two moxa sticks is always consistent regardless of how they burn. This improves the uniformity of moxibustion and ensures the therapeutic effect of moxibustion.

[0023] 3. By adjusting the crossbeam connecting the box and using the uprights to restrict and fix the box, the box cannot move horizontally, but can only move up and down. This does not affect the movement of the moxa stick up and down with the user's breathing, and also prevents the box from tipping over during the up and down movement, ensuring the stability of the box and preventing burns or fires caused by the box tipping over, thus improving safety.

Detailed Implementation

[0040] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] This invention provides, for example Figure 1-12The illustrated intelligent moxibustion device with fireproof function includes a box body 1 and two moxa sticks 2. The bottom of the box body 1 is arc-shaped to better fit the curve of the human body. The bottom of the moxa sticks 2 is located inside the box body 1. When in use, the bottom of the moxa sticks 2 is lit. A temperature sensor 8 is installed on the rear wall inside the box body 1. A controller 4 is provided on one side of the box body 1. A Bluetooth module 11 is provided on the front side of the box body 1. The temperature sensor 8 is located at the input end of the controller 4. The controller 4 is wirelessly connected to a mobile phone through the Bluetooth module 11. Multiple ventilation slots 102 are provided on both sides of the box body 1 to ensure sufficient oxygen for the burning of the moxa sticks 2.

[0042] This device is suitable for moxibustion on the back and abdomen. When using it, place the box 1 on the area requiring moxibustion, with the bottom of the box 1 in contact with the skin. The bottom of the moxa stick 2 is located inside the box 1 and lit. The heat generated by the moxa stick 2 stimulates the corresponding area, achieving the effects of dispelling cold and dampness, and promoting blood circulation. During this time, the user's mobile phone can connect to the controller 4 via Bluetooth module 11. The temperature sensor 8 senses the temperature inside the box 1 in real time during the moxibustion process, allowing the user to view the real-time temperature inside the box 1 on their mobile phone, thus avoiding burns caused by excessive heat. The moxibustion time should ideally be 20-30 minutes. The controller 4 senses the temperature, and the temperature can be viewed via Bluetooth on the mobile phone. This technology is a mature existing technology, and the technical issues involved, such as power supply and wiring, will not be elaborated here.

[0043] To ensure the stability of box 1 during moxibustion, such as Figure 1 , 8 As shown, a column 3 is provided on one side of the box body 1, a slide 303 is sleeved on the outer end of the column 3, an adjusting beam 301 is provided on the front side of the slide 303, and one end of the adjusting beam 301 is detachably connected to the box body 1.

[0044] The sliding block 303 is fixedly provided with an adjustment frame 304 sleeved on the outer end of the adjustment beam 301. The front side of the adjustment frame 304 is provided with a first fastening bolt by thread. The bottom end of the column 3 is fixedly provided with an installation frame 302. The bottom end of the installation frame 302 is provided with two second fastening bolts by thread.

[0045] Before moxibustion, the user lies flat, and the mounting bracket 302 is secured to the edge of the bed. Tightening the second fastening bolt fixes it to the bed edge. Then, by adjusting the sliding of the crossbeam 301 relative to the adjusting bracket 304, the entire box 1 is moved, adjusting its position to ensure it accurately lands on the area requiring moxibustion. Once the box 1 is in position, the first fastening bolt is tightened to fix the position of the adjusting crossbeam 301. In this way, during subsequent moxibustion, the box 1 cannot move horizontally forward, backward, left, or right; it can only move vertically. This vertical movement of the box 1 will cause the adjusting crossbeam 301 to... 1. The adjustable frame 304 moves up and down, the slide 303 slides vertically up and down along the column 3, and the box 1 moves up and down to accommodate the human body. When the box 1 is placed on the patient's chest, abdomen, or back, the patient's breathing will cause the patient's body surface to rise and fall, which will cause the box 1 to move up and down with the rise and fall. The bottom of the box 1 always keeps in contact with the user's body and does not interfere with the user's breathing. The box 1 cannot move horizontally and will not tip over during the up and down movement, ensuring the stability of the box 1 and avoiding burns or fires caused by the box 1 tipping over, thus improving safety.

[0046] During moxibustion, the moxa stick should be kept roughly vertical to avoid excessive tilting. Figure 2 , 3 As shown in Figure 6, the top of the box body 1 is provided with a detachable cover plate 101, and the cover plate 101 is provided with two installation tubes 5 that penetrate the cover plate 101. The tops of the two moxa sticks 2 extend to the top of the installation tubes 5 through the two installation tubes 5 respectively.

[0047] An annular airbag 501 is fixedly provided on the inner wall of the installation tube 5. The annular airbag 501 is sleeved on the outer end of the corresponding moxa stick 2. Two air storage tubes 6 are provided on the rear side of the box body 1, and the two air storage tubes 6 correspond to the two installation tubes 5 respectively.

[0048] The top end of the gas storage pipe 6 is fixedly provided with a gas delivery hose 603. The front end of the gas delivery hose 603 extends into the corresponding installation tube 5 and is fixedly connected to the annular airbag 501. An adjustment plug 601 is threadedly connected to the bottom opening of the gas storage pipe 6. Elastic clips 602 are provided on both sides of the gas storage pipe 6. The elastic clips 602 are fixed to the rear side of the box body 1. The elastic clips 602 are elastic and can hold the gas storage pipe 6 in place on the rear side of the box body 1.

[0049] Before moxibustion, insert the bottom end of the moxa stick 2 into the box 1 through the installation tube 5. At this time, the annular air bag 501 is fitted onto the outer end of the moxa stick 2. Since the adjusting plug 601 is connected to the air storage tube 6 by threads, rotating the adjusting plug 601 will allow the adjusting plug 601 to move relative to the air storage tube 6. When the adjusting plug 601 goes deeper into the air storage tube 6, it can squeeze the air inside the air storage tube 6, thereby increasing the air pressure. Conversely, it will decrease the air pressure. The air storage tube 6 is connected to the annular air bag 5 through the air delivery hose 603. The air pressure changes inside the air storage tube 6, when connected to 01, will also affect the annular airbag 501. When the air pressure in the air storage tube 6 increases, the annular airbag 501 will expand, and the inner space of the annular airbag 501 will become smaller. Conversely, when the air pressure in the annular airbag 501 decreases, the inner space of the annular airbag 501 will become larger. This allows the annular airbag 501 to be adjusted according to the thickness of the moxa stick 2, so that the inner space of the annular airbag 501 is slightly larger than the cross-sectional area of ​​the moxa stick 2. This allows the annular airbag 501 to restrict the moxa stick 2 and prevent the moxa stick 2 from tilting too much.

[0050] The burning ends of the two moxa sticks 2 are always kept at a constant distance from the human body, such as Figure 3 , 5 As shown in Figure 7, the bottom end of the mounting tube 5 is threaded with a sleeve 12, which is located inside the box body 1. Multiple isolation strips 1201 made of ceramic are fixed on the inner wall of the sleeve 12. The bottom end of the moxa stick 2 extends into the sleeve 12 and contacts the isolation strips 1201.

[0051] The moxa stick 2 is provided with a counterweight component 9 at the top. The counterweight component 9 includes a U-shaped frame 902. Both ends of the U-shaped frame 902 are fixed with arc-shaped pieces 901. The two arc-shaped pieces 901 are respectively clamped on both sides of the moxa stick 2. The top of the U-shaped frame 902 is provided with a counterweight block 903.

[0052] The moxa stick 2 is vertically inserted into the box 1 through the installation tube 5. The elasticity of the U-shaped frame 902 clamps the arc-shaped piece 901 to the top of the moxa stick 2. The counterweight 903 is used to appropriately increase the weight of the moxa stick 2. After lighting, the bottom end of the moxa stick 2 is inserted into the sleeve 12 and contacts the isolation strip 1201. The isolation strip 1201 is made of a high-temperature resistant material, so it can be in contact with the burning part at the bottom of the moxa stick 2 for a long time. As the moxa stick 2 continues to burn during the moxibustion process, the ash becomes loose and will fall downwards through the gaps between the isolation strips 1201. The moxa stick 2 will gradually shorten as a result. However, due to its own weight and the weight of the isolation strip, the moxa stick 2 will continue to shorten. Under the counterweight effect of component 9, the height of moxa stick 2 will gradually decrease, but the burning part at the bottom of moxa stick 2 will always be located at the isolation strip 1201. The height of the two sleeves 12 inside the box body 1 is pre-adjusted and the height of the two sleeves 12 is the same. Therefore, the height of the two isolation strips 1201 is also the same. This ensures that no matter how the two moxa sticks 2 burn, the height of the burning part at the bottom of the two is always the same in the box body 1 and the distance from the human body is always the same. This avoids the two moxa sticks 2 burning uncontrollably in a natural state, which would cause the two to be at different heights. Ensuring that the height of the two burning ends is the same can improve the uniformity of moxibustion and ensure the therapeutic effect of moxibustion.

[0053] The ash that falls during moxibustion needs to be extinguished promptly, such as... Figure 3 , 4 As shown in Figures 10 and 11, an isolation component 7 is provided on the inner wall of the box body 1. The isolation component 7 includes an iron isolation mesh 703 fixed on the inner wall of the box body 1. A cotton gauze 704 is provided at the top of the iron isolation mesh 703. The cotton gauze 704 is located at the bottom of the moxa stick 2. A sponge block 701 is placed at the top of the cotton gauze 704. The mesh density on the cotton gauze 704 is approximately the same as the mesh density on the iron isolation mesh 703. Ash cannot pass through either of them, while ensuring breathability so that heat can be transmitted.

[0054] A water storage box 10 is fixedly installed on the front wall of the inner wall of the box body 1. A plurality of drip nozzles 1001 are fixedly installed at the bottom of the water storage box 10. The drip nozzles 1001 are located above the sponge block 701. The size of the hole inside the drip nozzle 1001 is proportional to the dripping speed of the water droplets. The size of the hole of the drip nozzle 1001 is preset to control the dripping speed of the water droplets to 5-8 drops per minute.

[0055] Before moxibustion, water from the water storage box 10 drips down onto the sponge block 701 through the drip nozzle 1001, thus wetting the sponge block 701. The sponge block 701 comes into contact with the cotton gauze 704, thus wetting the cotton gauze 704 and keeping it moist. During moxibustion, the moisture on the cotton gauze 704 will evaporate, so the drip nozzle 1001 continuously replenishes water, keeping the cotton gauze 704 moist but without obvious water on the surface. In this way, the ash that falls from the burning end of the moxa stick 2 during moxibustion falls onto the cotton gauze 704, and the moist cotton gauze 704 wets the ash, preventing burns or fires caused by unextinguished sparks in the ash, effectively improving the fire resistance of the moxibustion device.

[0056] The water storage box 10 has two water injection holes at its top, and each water injection hole is equipped with a rubber stopper. Water can be added to the water storage box 10 by opening the rubber stopper. The sponge block 701 has two elastic strips 702 at its top. One end of the elastic strip 702 is connected to the inner wall of the box body 1. The elastic strip 702 uses its own elasticity to clamp the sponge block 701, so that the sponge block 701 fits against the cotton gauze 704.

[0057] The iron isolation net 703 is provided with multiple fixing components 13. Each fixing component 13 includes an insertion rod 1301 that passes through the iron isolation net 703 and the cotton gauze 704. A magnet 1302 is fixed to the top of the insertion rod 1301. The magnet 1302 is located at the top of the cotton gauze 704. The insertion rod 1301 connects the iron isolation net 703 and the cotton gauze 704 in series. The magnet 1302 attracts the iron isolation net 703 with magnetic force and presses it onto the surface of the cotton gauze 704, thereby fixing the cotton gauze 704 to the iron isolation net 703. The fixing can be released by removing the fixing component 13 from the iron isolation net 703, so that the cotton gauze 704 can be disassembled and replaced. The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
