Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine cupping therapy technology, and in particular relates to a traditional Chinese medicine cupping therapy chair. Background Technology

[0002] Cupping therapy, an important component of traditional Chinese medicine, involves applying cups to specific areas of the body to create a localized negative pressure environment. This achieves effects such as clearing the meridians, promoting blood circulation, reducing swelling, and relieving pain. It is widely used in clinical treatment and health maintenance. Cupping therapy mainly includes techniques such as stationary cupping and moving cupping. Stationary cupping requires controlling the appropriate suction intensity and duration, while moving cupping requires the cups to be moved back and forth across a specific area of ​​the body. A lubricant should be used during this process to reduce skin friction and damage. Currently, traditional Chinese cupping therapy relies heavily on manual operation, which has several shortcomings. Firstly, real-time monitoring and precise control of the suction intensity during cupping is difficult; excessive suction can easily lead to skin damage, while insufficient suction affects the therapeutic effect. Secondly, moving cupping requires medical staff to manually push the cups, which is labor-intensive, and it's difficult to maintain uniform speed and force, potentially causing patient discomfort or skin abrasion due to improper operation. Furthermore, existing cupping equipment often has limited functionality and lacks adaptive adjustment mechanisms for different cupping methods (such as stationary and moving cupping). Lubricant application is also mostly manual, making it difficult to coordinate with cup movement, thus affecting the automation and efficiency of the treatment.

[0003] To address the aforementioned issues, there is an urgent need to design a traditional Chinese medicine cupping chair that can accurately monitor and control the adsorption intensity, automatically complete the reciprocating movement of the cupping jars, and simultaneously spray lubricant, in order to improve the safety, effectiveness, and convenience of cupping therapy. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention effectively solves the pain points of traditional cupping therapy through structural innovation. The linkage mechanism composed of pressure measuring cylinders and other components can monitor the air pressure inside the adsorption tank in real time. When the pressure exceeds the threshold, it automatically stops pumping air and resumes pumping air when the pressure rises, precisely controlling the adsorption intensity and ensuring safe and effective treatment. The air pump-driven transmission system, in conjunction with a contact switch, enables the adsorption tank to move automatically back and forth. During the movement, lubricant is sprayed evenly and synchronously, reducing the labor intensity of medical staff and avoiding skin friction damage. The pipeline design allows switching between mobile and stationary cupping modes, and the pressure valve and other protective structures improve the reliability of the equipment. The technical solution adopted in this invention is as follows: a traditional Chinese medicine cupping therapy chair, including a chair body, a sliding frame symmetrically fixed on the back of the chair body, an air pump fixed on the back of the chair body, and a cupping therapy unit slidably mounted on the sliding frame; The cupping therapy unit includes a slider slidably mounted on a sliding frame, a spring-loaded telescopic rod fixed to the bottom of the slider, an adsorption canister fixed to the movable end of the spring-loaded telescopic rod, and a lubricant tank fixed to the bottom of the slider. The lubricant tank has an elongated nozzle at the end furthest from the slider and is used to store lubricant. The spring-loaded telescopic rod allows the adsorption canister to fit snugly against the patient's back. A pressure measuring cylinder is fixed to the adsorption canister and communicates with the interior of the adsorption canister. The pressure measuring cylinder is used to measure the gas content inside the adsorption canister. The pressure measuring cylinder has a pressure measuring baffle that slides inside. A spring is fixedly installed on the side wall of the pressure measuring baffle, and the other end of the spring is fixedly connected to the inner side wall of the pressure measuring cylinder. The spring can pull the pressure measuring baffle to reset after the air pressure in the adsorption tank increases. A blocking rod is fixedly installed on the side wall of the pressure measuring baffle. An air outlet cylinder is fixedly installed on the adsorption tank and communicates with the inside of the adsorption tank. The other end of the blocking rod is slidably installed in the air outlet cylinder. After the blocking rod slides a certain distance toward the adsorption tank, it can block the air outlet cylinder.

[0005] As a preferred technical solution of this invention, a piston is slidably installed inside the lubricant tank. The piston is used to squeeze the lubricant in the lubricant tank to spray out. A pressure relief port is opened on the side wall of the lubricant tank. When the air pressure in the lubricant tank rises to a certain threshold, the pressure relief port opens to prevent the air pressure in the lubricant tank from continuing to rise and causing damage to the device after all the lubricant in the lubricant tank has been sprayed out.

[0006] As a preferred technical solution of this invention, the air pump outlet is fixedly provided with an air outlet pipe, the air pump inlet is fixedly provided with an air inlet pipe, a two-way solenoid valve is fixedly provided on the side wall of the slider, a wheel cover is fixedly provided on the side wall of the slider, a pipe six is ​​provided through the air outlet pipe and the two-way solenoid valve, a pipe one is provided through the inside of the wheel cover and the two-way solenoid valve, a pipe two is provided through the inside of the wheel cover and the two-way solenoid valve, a pipe three is provided through the inside of the wheel cover and the inside of the lubricant tank, a pipe four is provided through the inside of the wheel cover and the inside of the lubricant tank, an impeller is rotatably provided inside the wheel cover, and the two-way solenoid valve can control the air flowing in from the six pipes to flow out from the two pipes or the one pipe. The air flowing into the wheel cover from the one pipe can drive the impeller to rotate forward and then flow into the lubricant tank from the three pipes, and the air flowing into the wheel cover from the two pipes can drive the impeller to rotate in the reverse direction and then flow into the lubricant tank from the four pipes.

[0007] As a preferred technical solution of this invention, a gear is coaxially fixed at the top of the impeller, and a rack is fixed on the sliding frame. The rack and gear are meshed together. When the impeller rotates forward, the gear moves away from the air pump under the action of the rack, thereby driving the adsorption tank to move away from the air pump. When the impeller rotates in reverse, the gear moves towards the air pump under the action of the rack, thereby driving the adsorption tank to move towards the air pump. One end of the slider is fixedly equipped with a contact switch, which is electrically connected to a two-way solenoid valve. The contact switch can control the two-way solenoid valve to allow air to flow from pipe one into the impeller housing, thereby causing the gear to move away from the air pump. The other end of the slider is fixedly equipped with a contact switch, which is electrically connected to a two-way solenoid valve. The contact switch can control the two-way solenoid valve to allow air to flow from pipe two into the impeller housing, thereby causing the gear to move towards the air pump.

[0008] As a preferred technical solution of this invention, a pressure valve is fixedly installed on the outlet pipe. The pressure valve opens after the air pressure in the outlet pipe rises to a certain threshold. A pressure valve is fixedly installed on the inlet pipe. The pressure valve opens after the air pressure in the inlet pipe drops to a certain threshold. A pipe seven is fixedly installed between the inlet pipe and the outlet pipe. The pressure valve can prevent the air pressure in the inlet pipe from continuously decreasing and causing damage to the device after the outlet pipe is blocked.

[0009] As another preferred technical solution of this scheme, one end of the pipe seven is connected to the air outlet, and the other end of the pipe seven is connected to the outside.

[0010] The beneficial effects of the present invention after adopting the above structure are as follows: (1) The air pump driven transmission system can realize the automatic reciprocating movement of the adsorption canister on the sliding frame through the cooperation of a two-way solenoid valve and a contact switch, replacing the traditional manual cupping operation. During the movement, the airflow generated by the impeller rotation synchronously squeezes the piston in the lubricant tank, so that the lubricant is evenly sprayed out from the long strip nozzle, which is precisely matched with the movement trajectory of the canister. This design not only reduces the labor intensity of medical staff, but also avoids skin friction damage caused by uneven force during manual operation through stable movement speed and force control, significantly improving the comfort and standardization of cupping therapy. (2) The linkage mechanism consisting of the pressure measuring cylinder, the pressure measuring baffle, and the spring can sense the changes in air pressure inside the adsorption tank in real time: when the air pressure is lower than the safety threshold, the sealing rod automatically blocks the air outlet cylinder and stops the suction to avoid skin damage; if the air pressure rises due to poor contact or other reasons, the spring pulls the pressure measuring baffle to reset and resumes suction to maintain a stable air pressure. This mechanism achieves precise control of the air pressure intensity during the cupping process, which not only ensures the treatment effect but also greatly reduces the risk of skin bruising and pain caused by uncontrolled air pressure in traditional manual operation; (3) Through the through-flow design of Pipeline 7 (Example 2), the equipment can flexibly switch between "canister moving" and "canister stationary" modes: when the canister is moving, the air path drives the canister to move back and forth and sprays lubricant simultaneously; when the canister is stationary, the transmission air path is cut off to keep the canister stationary and focus on stable air pressure control. In addition, the protective structures such as pressure valve 1, pressure valve 2 and pressure relief port effectively prevent damage to the air path system caused by abnormal air pressure, and improve the reliability and durability of the equipment.

[0014] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0015] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0016] Example 1, as Figures 1-6 As shown, the TCM cupping therapy chair of this embodiment includes a chair body 1, a sliding frame 2 symmetrically fixed on the back of the chair body 1, an air pump 4 fixed on the back of the chair body 1, and a cupping therapy unit 3 slidably mounted on the sliding frame 2. The cupping therapy unit 3 includes a slider 7 slidably mounted on a sliding frame 2, a spring-loaded telescopic rod 19 fixedly mounted on the bottom of the slider 7, an adsorption canister 10 fixedly mounted on the movable end of the spring-loaded telescopic rod 19, and a lubricant tank 13 fixedly mounted on the bottom of the slider 7. The lubricant tank 13 has an elongated nozzle at the end furthest from the slider 7 and is used to store lubricant. The spring-loaded telescopic rod 19 allows the adsorption canister 10 to fit snugly against the patient's back. A pressure measuring cylinder 11 is fixedly mounted on the adsorption canister 10, communicating with the interior of the adsorption canister 10, and is used to measure the air pressure inside the adsorption canister 10. A pressure measuring baffle 18 is slidably provided inside the pressure measuring cylinder 11. A spring 17 is fixedly provided on the side wall of the pressure measuring baffle 18. The other end of the spring 17 is fixedly connected to the inner side wall of the pressure measuring cylinder 11. The spring 17 can pull the pressure measuring baffle 18 to reset after the air pressure in the adsorption tank 10 increases. A blocking rod 12 is fixedly provided on the side wall of the pressure measuring baffle 18. An air outlet cylinder 16 is fixedly provided on the adsorption tank 10. The air outlet cylinder 16 is in communication with the inside of the adsorption tank 10. The other end of the blocking rod 12 is slidably provided in the air outlet cylinder 16. After the blocking rod 12 slides a certain distance toward the adsorption tank 10, it can block the air outlet cylinder 16.

[0017] The lubricant tank 13 is equipped with a piston 26 that slides inside. The piston 26 is used to squeeze the lubricant in the lubricant tank 13 to spray it out. The side wall of the lubricant tank 13 is provided with a pressure relief port 20. When the air pressure in the lubricant tank 13 rises to a certain threshold, the pressure relief port 20 opens to prevent the air pressure in the lubricant tank 13 from continuing to rise and causing damage to the device after all the lubricant in the lubricant tank 13 has been sprayed out.

[0018] The air pump 4 has an air outlet pipe 29 fixedly installed at its outlet and an air inlet pipe 30 fixedly installed at its inlet. A two-way solenoid valve 9 is fixedly installed on the side wall of the slider 7. A wheel cover 14 is fixedly installed on the side wall of the slider 7. A pipe 6 27 runs through the air outlet pipe 29 and the two-way solenoid valve 9. Pipes 1 22 and 23 run through the inside of the wheel cover 14 and the two-way solenoid valve 9. Pipes 3 24 and 4 25 run through the inside of the wheel cover 14 and the inside of the lubricant tank 13. An impeller 21 rotates inside the wheel cover 14. The two-way solenoid valve 9 can control the air flowing in from pipe 6 27 to flow out from pipe 2 23 or pipe 1 22. The air flowing into the wheel cover 14 from pipe 1 22 can drive the impeller 21 to rotate forward and then flow into the lubricant tank 13 from pipe 3 24. The air flowing into the wheel cover 14 from pipe 2 23 can drive the impeller 21 to rotate in the opposite direction and then flow into the lubricant tank 13 from pipe 4 25.

[0019] The impeller 21 is coaxially fixed with a gear 6 at its top, and a rack 5 is fixed on the sliding frame 2. The rack 5 and gear 6 are meshed together. When the impeller 21 rotates forward, the gear 6 moves away from the air pump 4 under the action of the rack 5, thereby driving the adsorption tank 10 to move away from the air pump 4. When the impeller 21 rotates in the reverse direction, the gear 6 moves closer to the air pump 4 under the action of the rack 5, thereby driving the adsorption tank 10 to move closer to the air pump 4. One end of the slider 7 is fixed with a contact switch 1 8, which is electrically connected to a two-way solenoid valve 9. The contact switch 1 8 can control the two-way solenoid valve 9 to allow air to flow from pipe 22 into the wheel cover 14, thereby causing the gear 6 to move away from the air pump 4. The other end of the slider 7 is fixed with a contact switch 2 15, which is electrically connected to the two-way solenoid valve 9. The contact switch 2 15 can control the two-way solenoid valve 9 to allow air to flow from pipe 2 23 into the wheel cover 14, thereby causing the gear 6 to move closer to the air pump 4.

[0020] Pressure valve 31 is fixedly installed on the outlet pipe 29. Pressure valve 31 opens when the air pressure in the outlet pipe 29 rises to a certain threshold. Pressure valve 32 is fixedly installed on the inlet pipe 30. Pressure valve 32 opens when the air pressure in the inlet pipe 30 drops to a certain threshold. Pipe 28 is fixedly installed between the inlet pipe 30 and the outlet cylinder 16. Pressure valve 32 can prevent the air pressure in the inlet pipe 30 from continuously decreasing and causing damage to the device after the outlet cylinder 16 is blocked.

[0021] In practical use: When a patient needs cupping, lubricant is injected into the lubricant tank 13. After the patient sits on the chair body 1 with their back pressed against the backrest, the opening edge of the suction cup 10 is pressed against the patient's back under the action of the elastic telescopic rod 19. The air pump 4 is started, and the air pump 4 draws air from the suction cup 10 through the air inlet pipe 30, pipe 28, and air outlet pipe 16. Under the action of negative pressure, the suction cup 10 performs cupping on the patient's back. The air pressure inside the suction cup 10 decreases, and the pressure measuring baffle 18 slides towards the inside of the suction cup 10 under the action of negative pressure. The pressure measuring baffle 18 drives the sealing rod 12 to move. When the blocking rod 12 moves, it blocks the air outlet 16, and the air pump 4 stops pumping air from the adsorption tank 10 to prevent the air pressure inside the adsorption tank 10 from continuously decreasing and causing harm to the patient. If the adsorption tank 10 separates from the patient's skin or other reasons cause the air pressure inside it to rise, the pressure measuring baffle 18 moves away from the adsorption tank 10 under the action of the spring 17, and the blocking rod 12 stops blocking the air outlet 16. The pipe 28 continues to pump air from the adsorption tank 10 to maintain the air pressure of the adsorption tank 10. At the same time as the air pump 4 is started, the airflow generated by the air pump 4 flows through the air outlet pipe 29. The airflow flows into the two-way solenoid valve 9 through pipe 6 27. Initially, the two-way solenoid valve 9 only allows airflow to flow from pipe 1 22 into the impeller cover 14. The airflow, after flowing into the impeller cover 14 through pipe 1 22, drives the impeller 21 to rotate forward and then flows out through pipe 3 24. The forward rotation of the impeller 21 drives the gear 6 to rotate. Under the action of the rack 5, the gear 6 moves in a direction away from the air pump 4. The movement of the gear 6 drives the impeller 21, the impeller cover 14, the slider 7, and the elastic telescopic rod 19 to move, thereby driving the adsorption tank 10 to move. When the slider 7 moves to the top of the sliding frame 2, the contact switch 2 15 contacts the sliding frame 2, and the contact... Switch 2 15 controls the two-way solenoid valve 9 to allow air to flow into the wheel cover 14 only through pipe 2 23. The air flowing into the wheel cover 14 through pipe 2 23 drives the impeller 21 to rotate in the opposite direction and then flows out through pipe 4 25. The reverse rotation of the impeller 21 drives the gear 6 to move towards the direction closer to the air pump 4, which in turn drives the slider 7 and the adsorption tank 10 to move. When the slider 7 moves to the bottom of the sliding frame 2, the contact switch 1 8 contacts the sliding frame 2. The contact switch 1 8 controls the two-way solenoid valve 9 to change back to allow air to flow into the wheel cover 14 only through pipe 22, thereby realizing the reciprocating movement of the adsorption tank 10 and performing cupping on the patient. Air flowing from pipe 24 or pipe 25 into lubricant tank 13 increases the air pressure in lubricant tank 13, causing pressure relief port 20 to slide away from slider 7. Piston 26 slides and squeezes the lubricant in lubricant tank 13, which is then sprayed out from the nozzle to lubricate the patient's back, preventing the device from causing unnecessary damage to the patient's skin. The auxiliary device performs cupping on the patient.

[0022] Example 2, as Figures 7-8As shown, the difference between this embodiment and Embodiment 1 is that the cupping unit 3 array is arranged on the sliding frame 2, one end of the pipe 7 28 is connected to the air outlet 16, and the other end of the pipe 7 28 is connected to the outside.

[0023] In practical use, when the patient needs to perform static cupping, after the patient sits on the chair body 1, the air pump 4 is started, and the suction cup 10 will perform cupping on the patient's back in the same way as in Example 1. Since the pipe 7 28 is connected to the outside, the impeller 21 will not rotate, and the gear 6 will not move along the rack 5, and the suction cup 10 will not move accordingly, so the suction cup 10 performs static cupping on the back.

[0024] In summary, if a person skilled in the art, inspired by this invention, designs a similar structure and embodiment without departing from the spirit of the invention, such design should fall within the scope of protection of this invention.
