Description

Technical Field

[0001] This invention relates to the technical field of instruments for physiotherapy that locate or target specific reflex points on the human body, and particularly to a moxibustion device for the back that provides a comfortable moxibustion atmosphere for the user. The device can rotate circumferentially and move up and down, causing the burning point of the corresponding moxa stick to change regularly. This allows the acupoints in the moxibustion area on the back to spread outward from the center, enhancing the moxibustion effect and improving the user experience. Background Technology

[0002] The benefits and effects of moxibustion on the back include: First, detoxification and skin beautification: The back contains the bladder meridian. Moxibustion on the bladder meridian on the back helps promote metabolism, resulting in fair and radiant skin. It also helps expel cold and dampness from the body and improves sleep quality. Second, blood circulation and stasis removal: For women, moxibustion on the back can also dredge the meridians, promoting blood circulation and treating dysmenorrhea, amenorrhea, and irregular menstruation caused by blood stasis. Third, warming the meridians and dispelling cold, supporting yang and consolidating the body: Moxibustion can be used to treat diseases caused by yang deficiency, back pain, physical weakness, and coldness in the back.

[0003] One major reason why existing moxibustion devices or systems are difficult to bring into ordinary households and widely applied is that when moxibustion materials (mugwort leaves, moxa cakes, or moxa sticks) are burned, they produce a large amount of highly irritating and oily moxa smoke. Moreover, most of the oily smoke and odors exist in the form of PM2.5, which greatly affects the moxibustion environment around the therapist. To solve the problem of moxa smoke pollution.

[0004] A search of CN109498437A reveals a moxibustion fixation device for internal medicine in traditional Chinese medicine. The device comprises a base with a support column fixedly connected to it, and multiple casters evenly distributed circumferentially below the base. A cylinder is rotatably connected above the support column, with a piston rod slidably and sealed on one side of the cylinder. A hanging rod is rotatably connected to the end of the piston rod, and a moxibustion disc is fixedly connected to the lower end of the hanging rod. An iron plate is fixedly connected to the lower surface of the moxibustion disc, and multiple magnets are adsorbed onto the iron plate. The lower surface of the magnets is elastically connected to a moxibustion cylinder via springs. The lower part of the cylinder is rotatably connected to the upper end of a connecting rod, and the lower end of the connecting rod is rotatably connected to a threaded collar, which is threadedly connected to a lead screw. This device uses the cylinder to drive the piston rod to extend and retract, thereby moving the hanging rod and the moxibustion disc. The moving moxibustion disc moves the moxibustion cylinder, facilitating position adjustment. The spring-loaded moxibustion cylinder allows for a close and precise fit to the back of patients of varying heights. Simultaneously, the lead screw uses the threaded force to move the threaded collar longitudinally, which in turn drives the connecting rod to swing the cylinder, achieving height adjustment. This technical solution cannot provide users with a comfortable moxibustion environment, especially for users with respiratory diseases, and may even aggravate their condition. How can we provide users with a comfortable moxibustion environment and develop a back moxibustion device that can be widely promoted and applied? Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Therefore, it proposes a back moxibustion device that can provide users with a comfortable moxibustion atmosphere. This device can rotate circumferentially and move up and down, causing the corresponding moxa stick burning point to change regularly. This allows the moxa knots in the back moxibustion area to spread outward from the center, enhancing the moxibustion effect and improving the user experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A back moxibustion therapy device includes a moxibustion cover and a walking mechanism.

The top of the moxibustion cover is equipped with a smoke collection pipe, and the bottom of the moxibustion cover is equipped with an isolation net. The walking mechanism is equipped with a smoke filter and a lifting mechanism. The output end of the lifting mechanism is equipped with a slide that moves up and down relative to the walking mechanism and is used to install the moxibustion cover. The smoke collection pipe and the slide are connected to the smoke filter through an internal pipe.

[0008] Based on this back moxibustion therapy device, the following improvements are made: the moxibustion therapy component includes a support base installed inside the moxibustion therapy cover, and a moxa stick connecting frame is movably arranged on the support base for connecting several moxa stick frames.

[0009] Based on this back moxibustion therapy device, the following improvements are made: the support base is equipped with a lifting structure, which can be an X-shaped hinge structure, a screw and nut structure, a belt-driven lifting structure, or a cylinder telescopic structure.

[0010] Based on this back moxibustion therapy device, the following improvements are made: The moxa stick connecting frame is equipped with a rotating body, a differential body, and a driving body. The rotating body and the differential body are rotatably mounted on the moxa stick connecting frame. The driving body forms a transmission pair with the rotating body and the differential body through a gear pair. The rotating body and the differential body form a differential assembly. The differential body passes through the rotating body and is connected to the moxa stick frame.

[0011] Based on this back moxibustion therapy device, the following improvements are made: multiple concentric circumferential wave rings are provided on one side of the rotating body relative to the differential body, and guide ring grooves are provided on the circumferential wave rings. Several connecting bodies corresponding to the positions of the moxa sticks are movably connected to the differential body by springs. The connecting bodies are connected to the corresponding moxa sticks, and the top of the connecting bodies abuts against the inside of the guide ring grooves.

[0012] Based on this back moxibustion therapy device, the following improvements are made: the output end of the drive body is equipped with two main transmission gears through a coupling, and driven gears are evenly distributed on the rotating body and the differential body. The two main transmission gears and their corresponding driven gears form gear transmission pairs with different transmission ratios.

[0013] Based on this back moxibustion therapy device, the following improvements are made: several protrusions are evenly spaced at the bottom of the guide ring groove, and the connecting body passing through the corresponding protrusions will vibrate accordingly.

[0014] Based on this back moxibustion therapy device, the following improvements are made: the moxa stick frame is equipped with a compression spring and a heat insulation sheet, and the inner wall of the moxa stick frame is provided with flexible limiting teeth arranged in a circumferential direction.

[0015] Based on this back moxibustion therapy device, the following improvements are made: a temperature sensor is installed inside the moxibustion cover near the isolation net, a laser rangefinder is installed on the moxa stick connecting frame, and a reflective sheet corresponding to the position of the laser rangefinder is installed on the top of the moxibustion cover.

[0016] Based on this back moxibustion therapy device, the following improvements are made: a negative pressure generator is installed inside the walking mechanism for connecting to a smoke filter.

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

[0018] This invention employs a method that allows moxa smoke to be collected and filtered through a smoke collection tube and a smoke filter before being discharged, preventing the smoke from diffusing into the air and thus providing users with a comfortable moxibustion environment.

[0019] This invention employs an adjustable moxa stick holder to adjust the burning point of the moxa stick or the temperature of moxibustion on the back, allowing users to customize the experience and enhance the overall feel of the treatment.

[0020] This invention employs a method that can achieve differential speed and adjust the state of the corresponding moxa stick frame vertically and circumferentially, thereby allowing the temperature of the back moxibustion to change in a timely manner. This enables the stagnation on the back to be cleared in all directions under the heat conduction or along the movement direction of the moxa stick frame, resulting in a better moxibustion effect.

[0021] This invention employs a structure for controllable back moxibustion temperature. The lifting structure on the support base allows for appropriate adjustment of the distance between the moxa stick burning point and the back, thereby adjusting the back moxibustion temperature. Simultaneously, a temperature sensor enables precise temperature detection. A laser rangefinder and reflector form a structure that effectively controls and adjusts the height and position of the moxa stick frame and the moxa stick connecting frame, resulting in a rich overall user experience.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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, they should not be construed as limitations on this invention.

[0037] Example 1: As Figure 1 , 2 As shown in Figures 3 and 11, a back moxibustion therapy device includes a moxibustion cover 10 and a walking mechanism 20. The moxibustion cover 10 is equipped with a position-adjustable moxibustion component. Several evenly distributed moxa sticks 30 are arranged on the moxibustion component. The top of the moxibustion cover 10 is equipped with a smoke collection pipe 70, and the bottom of the moxibustion cover 10 is equipped with an isolation net 40. The walking mechanism 20 is equipped with a smoke filter 50 and a lifting mechanism. The output end of the lifting mechanism is equipped with a slide 60 that moves up and down relative to the walking mechanism 20 and is used to install the moxibustion cover 10. The smoke collection pipe 70 and the slide 60 are connected to the smoke filter 50 through an internal pipe 80. The walking mechanism 20 includes a control box and a moxibustion cover. The bottom of the control box is equipped with four universal self-locking wheels. The lit moxa stick needs to be installed on the moxa stick frame 30 in advance, and the isolation net 40 needs to be installed at the bottom of the moxibustion cover 10. The walking mechanism 20 can move the control box to a suitable position and complete the self-locking. The height of the sliding seat 60 of the moxibustion cover 10 is adjusted to a suitable height by using the control panel on the control box and the built-in program to control the lifting mechanism. That is, the moxibustion cover 10 is located slightly above the patient's back, and the back moxibustion begins. The moxa smoke generated by the burning moxa stick can enter the smoke filter 50 through the smoke collection pipe 70 and the built-in pipe 80 for filtration and exhaust. The moxa smoke can enter the smoke collection pipe 70 by using the siphon principle.

[0038] Example 2: Figure 4 , Figure 5As shown, the following improvements are made based on Embodiment 1. For example, the moxibustion component includes a support base 11 installed inside the moxibustion cover 10. A moxa stick connecting frame 90 is movably arranged on the support base 11, and the moxa stick connecting frame 90 is used to connect several moxa stick frames 30. The moxa stick connecting frame 90 is equipped with a movable block, a transmission screw, a micro drive motor, and a fixed block. Both the movable block and the fixed block are used to install the moxa stick frames 30. The movable block has two sets located on both sides of the fixed block and connected by a transmission screw thread. The two sets of movable blocks move in opposite directions. A lifting structure is provided on the support base 11. The lifting structure can be an X-type hinge structure, a screw and nut structure, a belt-driven lifting structure, or a cylinder telescopic structure, preferably a cylinder telescopic structure. The moxa stick connecting frame 90 can be adjusted left and right relative to the space inside the moxibustion cover 10 to adapt to the differences in back moxibustion positions for different people. By adjusting the height of the moxa stick connecting frame 90 through the lifting structure, the distance between the burning point of the moxa stick and the skin on the back can be adjusted, thereby controlling different back moxibustion temperatures.

[0039] Example 3: As Figure 6 , 7 As shown in Figure 8, the following improvements are made based on any of the above embodiments. For example, the moxa stick connecting frame 90 is equipped with a rotating body 91, a differential body 92, and a driving body 93. The rotating body 91 and the differential body 92 are rotatably mounted on the moxa stick connecting frame 90. The driving body 93 forms a transmission pair with the rotating body 91 and the differential body 92 through a gear pair. A differential assembly is formed between the rotating body 91 and the differential body 92. The differential body 92 passes through the rotating body 91 and is connected to the moxa stick frame 30. The driving body 93 drives the rotating body 91 and the differential body 92 to rotate through the gear pair, and there is a differential phenomenon between the two, thereby achieving a differential effect. This allows the position of the moxa stick frame 30 to be continuously adjusted, causing the stagnation in the back moxibustion area to disperse to the surrounding areas.

[0040] The rotating body 91 has multiple concentric circumferential wave ring surfaces 94 on one side relative to the differential body 92, and guide ring grooves 95 are provided on the circumferential wave ring surfaces 94. Several connecting bodies 96 corresponding to the positions of the moxibustion column frame 30 are movably connected to the differential body 92 through springs 97. The connecting body 96 is connected to the corresponding moxibustion column frame 30, and the top of the connecting body 96 abuts against the inside of the guide ring groove 95.

[0041] Two main transmission gears 98 are mounted on the output end of the drive body 93 via a coupling. Driven gears 99 are evenly distributed on the rotating body 91 and the differential body 92. The two main transmission gears 98 and their corresponding driven gears 99 form gear transmission pairs with different transmission ratios.

[0042] In use, the drive body 93 (micro motor) drives the rotating body 91 and the differential body 92 through the gear transmission pair to achieve the differential effect. At the same time, since the rotating body 91 is provided with a circumferential wave ring surface 94, it can also achieve up and down reciprocating motion in the vertical direction when the connecting body 96 rotates. This enables several moxa sticks 30 pairs of back moxibustion areas to achieve efficient unblocking treatment through thermal conductivity, and at the same time, thermal conductivity can also achieve the corresponding massage effect.

[0043] Example 4: Figure 7 As shown, the following improvements are made to Example 3: The bottom of the guide ring groove 95 is provided with several equally spaced protrusions 951, causing the connecting body 96 to vibrate accordingly. While the connecting body 96 rotates, the corresponding protrusions 951 cause the moxa stick frame 30 to vibrate, preventing the moxa ash from falling off in time and affecting the back moxibustion temperature.

[0044] Example 5: Figure 12 As shown, the following improvements are made based on any of the above embodiments: a temperature sensor 12 is installed inside the moxibustion cover 10 near the isolation net 40, a laser rangefinder sensor 13 is installed on the moxa stick connecting frame 90, and a reflective sheet 14 corresponding to the position of the laser rangefinder sensor 13 is installed on the top of the moxibustion cover 10. The temperature sensor 12 allows for real-time monitoring of the temperature of the moxibustion cover 10 near the isolation net on the control panel, thereby enabling real-time observation of the back moxibustion temperature. The laser rangefinder sensor 13 and the reflective sheet 14 allow for effective height adjustment and corresponding temperature adjustment.

[0045] Example 6: As Figure 11 As shown, the following improvement is made based on any of the above embodiments: a negative pressure generator 100 is installed inside the walking mechanism 20 for connecting to the smoke filter 50. The negative pressure generator 100 can prevent the smoke from escaping, thus improving the therapeutic atmosphere for the user.

[0046] Example 7: Figure 9 and Figure 10 As shown, the following improvement is made based on any of the above embodiments: The moxa stick holder 30 is internally equipped with a driving mechanism and a moxa stick mounting body. The driving mechanism includes an active unit located on the side of the mounting body 14 near the bottom, an energy storage unit located on the top inner side of the mounting body 14, and a connecting channel 110 connecting the energy storage unit and the active unit. The active unit actively supplies energy to the energy storage unit, charging the energy storage unit and automatically pushing the moxa stick mounting body closer to the moxibustion point.

[0047] The active unit includes a pump body 141 mounted on the mounting body 14. A manifold 1411 is provided on one side of the pump body 141. A piston 1412 and a shape memory alloy 1413 partially exposed on the outside of the mounting body 14 are provided inside the manifold 1411. Two unidirectional conduction structures 1414 are installed inside the pump body 141, and the two unidirectional conduction structures 1414 are located on both sides of the manifold 1411. The air outlet of the pump body 141 is connected to the connecting channel 110. As the moxa stick burns, the combustion point gradually shifts backward, reaching the shape memory alloy 1413. This causes the shape memory alloy 1413 to reach an extremely high temperature, thus expanding within the manifold 1411. This allows the piston 1412 to move closer to the pump body 141. Gas inside the pump body 141 enters the energy storage unit through the one-way passage structure 1414 and the connecting channel 110 to complete energy storage and propel the moxa stick mounting body. The gas does not exit through the other one-way passage structure 1414. When the moxa stick's combustion point... After moving away from the shape memory alloy 1413, the temperature decreases and the shape memory alloy drives the piston 1412 to reset, allowing gas to enter the pump body 141 through another one-way conduction structure 1414. The gas inside the energy storage unit cannot pass through the corresponding one-way conduction structure 1414, allowing the moxa stick holder 15 to complete one feeding cycle. The feeding distance is the extension and retraction of the shape memory alloy 1413 each time multiplied by the cross-sectional area of ​​the manifold 1411, thus ensuring that the feeding distance is consistent and very precise each time. This cycle is repeated multiple times until the moxa stick burns out, completing one moxibustion treatment.

[0048] like Figure 9 As shown, the energy storage unit includes an elastic energy storage body 142 disposed inside the mounting body 14. The elastic energy storage body 142 has a hollow structure and is connected to the connecting channel 110. The elastic energy storage body 142 includes a positioning plate 1421 fixedly installed on the top of the inner side of the mounting body 14, a movable plate 1422 movably installed on the inner side of the mounting body 14, a plurality of circumferentially distributed drive rods 1423 connected at both ends between the positioning plate 1421 and the movable plate 1422 respectively, and an elastic contraction structure 1424 disposed in the middle of the plurality of drive rods 1423. The elastic contraction structure 1424 is connected to the connecting channel 110. The movable plate 1422 is fixedly installed on the moxibustion column mounting body and the movable plate 1422 is an insulating plate. The moxibustion column mounting body slides relative to the mounting body 14 and also rotates. A fixed amount of gas enters unidirectionally through the connecting channel 110, causing the elastic telescopic structure 1424 to be quantitatively charged. This ensures that the feeding distance of the movable disc 1422 is consistent and precise each time. As the movable disc 1422 completes its feeding action, it rotates, causing the combustion point to rotate and thus dispersing any stagnation within the moxibustion point. Furthermore, a scraper installed inside the mounting body 14 removes ash, preventing unremoved ash from affecting the effective warmth sensation at the acupoints. The elastic telescopic structure 1424 is an airbag with an exhaust port equipped with an exhaust valve.

[0049] The unidirectional conduction structure 1414 includes two adhered electrostatic adsorption films. The open ends of the electrostatic adsorption films are fixed to the air inlet end of the pump body 141, and the electrostatic adsorption films are located inside the pump body 141. Through the adhesion effect of the two sets of unidirectional conduction structures 1414, gas can only enter in one direction and exit in one direction, thereby completing the charging of the energy storage unit.

[0050] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
