Description

Technical Field

[0001] This application relates to the field of traditional Chinese medicine cupping technology, and more specifically, to a cupping device for external treatment in traditional Chinese medicine. Background Technology

[0002] Cupping therapy, a traditional external treatment method in Traditional Chinese Medicine, has a long history. Traditional cupping generates negative pressure by burning alcohol, which has certain therapeutic effects but carries the risk of burns, and the degree of negative pressure is difficult to control precisely. With the development of technology, modern cupping devices have gradually emerged. Some of these devices use a suction-based negative pressure generation principle, which improves safety. However, the valve stem at the top of the device is easily displaced by external forces, leading to a decrease in the sealing performance of the top.

[0003] In response, Chinese patent application number CN202221778939.7 discloses a traditional Chinese medicine cupping therapy device. During use, if it is necessary to move the valve stem to allow air to enter the main body, the transparent protective cover can be pulled upwards, causing the connecting rod to slide in the same direction within the receiving groove. The connecting rod causes the iron block to separate from the magnet, and the iron block also causes the slider to slide in the same direction within the sliding groove until the slider slides to the other side of the groove. Then, the transparent protective cover is rotated, causing the connecting rod to rotate in the same direction. The connecting rod rotates around the iron block via a pivot, thus exposing the valve stem. Finally, the valve stem can be moved. This structure can protect the valve stem, preventing it from shifting under external forces.

[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this utility model discovered that the above-mentioned technology has at least the following technical problems:

[0005] 1. The above-mentioned protective cover has a complex structure, including multiple moving parts such as iron blocks, magnets, and connecting rods, resulting in high manufacturing costs;

[0006] 2. The above solution requires two actions to release air: pulling up and rotating the protective cover, and then pulling up the valve stem. Similarly, the protective cover needs to be opened when evacuating air, which is inconvenient. Utility Model Content

[0007] To overcome the above deficiencies, this application provides a cupping device for external treatment in traditional Chinese medicine, which aims to improve the problems mentioned in the background art.

[0008] This application provides a cupping device for external treatment in traditional Chinese medicine, including a cupping body, a one-way valve, and an exhaust button. The one-way valve includes a valve core and is fixedly connected to the upper end of the cupping body. The exhaust button is movably connected to the one-way valve and abuts against the valve core at a specific angle. The valve core is recessed within the exhaust button.

[0009] In one specific implementation, the one-way valve further includes a valve body, which is fixedly connected to the upper end of the tank. The valve body has a conical hole, and the valve core is movably sealed in the conical hole.

[0010] During the above process, the negative pressure inside the tank draws the valve core onto the conical hole to achieve a self-sealing effect.

[0011] In one specific implementation, a guide bar is fixedly connected to the inner wall of the valve body, and the guide bar is slidably connected to the outer circle of the valve core.

[0012] In the above implementation process, four guide bars are provided to stabilize the posture of the valve core and ensure the valve core fits and seals with the conical hole.

[0013] In one specific implementation, a sealing ring is provided on the outer circumference of the valve body to abut against the exhaust button.

[0014] In the above implementation process, the sealing ring is used to seal between the exhaust button and the valve body and to provide a certain amount of damping.

[0015] In one specific implementation, the exhaust button includes a rotating cylinder that is rotatably connected to the valve body, and a tapered opening is provided at the upper end of the rotating cylinder.

[0016] In the above process, when the drum rotates, it can stop at the current position at any time due to the damping effect of the sealing ring. The conical opening on the drum is used to connect with the air pump, so it can be directly connected when pumping air without any other operation, making the operation simple.

[0017] In one specific implementation, both the outer circle of the exhaust button and the outer circle of the one-way valve are provided with axial positioning strips.

[0018] In the above process, when the upper and lower positioning bars are aligned, it means that the exhaust button has been rotated to a specific angle, and the valve core can be pulled out. The positioning bars can be used to judge whether they are aligned by touch when the rotating drum is pinched.

[0019] In one specific implementation, a support rod is fixedly connected to the inner wall of the rotating drum, and a stop rod is fixedly connected to the valve core, with the support rod abutting against the stop rod.

[0020] In the above process, when the support rod and the abutment rod are misaligned, the upward-pulling cylinder cannot lift the valve core. However, when the support rod and the abutment rod are aligned, the upward-pulling cylinder can lift the abutment rod upward through the support rod, thereby lifting the valve core and releasing the air.

[0021] In one specific implementation, a retaining ring is provided on the inner wall of the rotating drum, the retaining ring being slidably connected to the outer circle of the valve body, and the retaining ring abutting against the sealing ring.

[0022] In the above process, when installing the exhaust button, insert the rotating drum downwards onto the valve body, with the retaining ring passing over the sealing ring to complete the installation. The valve core is blocked by the support rod and is also restricted. The retaining ring has a range of axial movement below the sealing ring, which is the axial movement range of the rotating drum.

[0023] Compared with the prior art, the beneficial effects of this application are: the exhaust button protects the valve core, avoiding accidental contact with the valve core that could lead to air leakage; the exhaust button only contacts the valve core at a specific angle, so accidental contact with the exhaust button will hardly affect the valve core; when releasing air, simply pinch the exhaust valve and rotate it to the specified angle to pull out the valve core, making the operation simple.

[0030] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0031] Please see Figures 1-4This application provides a cupping device for external treatment in Traditional Chinese Medicine, including a cupping body 10, a one-way valve 20, and an exhaust button 30. The one-way valve 20 includes a valve core 21 and is fixedly connected to the upper end of the cupping body 10. The exhaust button 30 is movably connected to the one-way valve 20, and the exhaust button 30 abuts against the valve core 21 at a specific angle, with the valve core 21 recessed within the exhaust button 30. The exhaust button 30 protects the valve core 21, preventing accidental contact and leakage. Since the exhaust button 30 only abuts against the valve core 21 at a specific angle, accidental contact with the exhaust button 30 has almost no impact on the valve core 21. To release air, simply pinch the exhaust valve and rotate it to the designated angle to pull out the valve core 21; the operation is simple.

[0032] Please see Figures 1-4 The one-way valve 20 also includes a valve body 22, which is fixedly connected to the upper end of the tank 10. A conical hole is provided on the valve body 22, and the valve core 21 is movably sealed in the conical hole. The negative pressure inside the tank 10 draws the valve core 21 onto the conical hole to achieve a self-sealing effect.

[0033] Please see Figures 1-4 A guide bar 23 is fixedly connected to the inner wall of the valve body 22, and the guide bar 23 is slidably connected to the outer circle of the valve core 21. Four guide bars 23 are provided to stabilize the posture of the valve core 21 and ensure the valve core 21 fits and seals with the conical hole.

[0034] Please see Figures 1-4 A sealing ring 24 is provided on the outer circumference of the valve body 22 to abut against the exhaust button 30. The sealing ring 24 is used to seal between the exhaust button 30 and the valve body 22 and provides a certain amount of damping.

[0035] Please see Figures 1-4 The exhaust button 30 includes a rotating cylinder 31, which is rotatably connected to the valve body 22. A conical opening 32 is provided at the upper opening of the rotating cylinder 31. When the rotating cylinder 31 rotates, it can stop at the current position at any time due to the damping effect of the sealing ring 24. The conical opening 32 on the rotating cylinder 31 is used to connect with the air pump, so it can be directly connected when pumping air without any other operation, making the operation simple.

[0036] Please see Figures 1-4 Both the outer circumference of the exhaust button 30 and the outer circumference of the one-way valve 20 are provided with axial positioning strips 40. When the upper and lower positioning strips 40 are aligned, it means that the exhaust button 30 has been rotated to a specific angle, and the valve core 21 can be pulled out. The positioning strips 40 can be used to judge whether they are aligned by touch when the rotating cylinder 31 is pinched.

[0037] Please see Figures 1-4A support rod 33 is fixedly connected to the inner wall of the rotating drum 31, and a stop rod 25 is fixedly connected to the valve core 21. The support rod 33 and the stop rod 25 abut against each other. When the support rod 33 and the stop rod 25 are misaligned, pulling up the rotating drum 31 will not lift the valve core 21. However, when the support rod 33 and the stop rod 25 are aligned, pulling up the rotating drum 31 can lift the stop rod 25 upward through the support rod 33, thereby lifting the valve core 21 and releasing air.

[0038] Please see Figures 1-4 The inner wall of the rotating drum 31 is provided with a retaining ring 34, which is slidably connected to the outer circle of the valve body 22 and abuts against the sealing ring 24. When installing the exhaust button 30, the rotating drum 31 is inserted downwards onto the valve body 22, and the retaining ring 34 passes over the sealing ring 24 to achieve the installation of the two. The valve core 21 is blocked by the support rod 33, and the valve core 21 is also restricted. The retaining ring 34 has an axial range of motion below the sealing ring 24, and this range is the axial movement range of the rotating drum 31.

[0039] The working principle of this cupping device used in traditional Chinese medicine external treatment is as follows: the valve body 22 and the cup body 10 are integrally injection molded, and the exhaust button 30 is also integrally injection molded. The sealing ring 24 is fitted onto the outer circle of the valve body 22. The valve core 21 is placed into the valve body 22, and then the rotating cylinder 31 is fitted onto the valve body 22. The retaining ring 34 passes over the sealing ring 24 to achieve connection. There are few parts, and assembly is convenient. After the air is drawn out, the exhaust button 30 is rotated until the upper and lower positioning strips 40 are staggered. The damping effect of the sealing strip can maintain the current angle of the exhaust button 30. The valve core 21 is recessed into the exhaust button 30 and cannot be accidentally touched. When the exhaust button 30 is accidentally touched, the exhaust button 30 will not be activated. Neither rotating nor pulling will remove the valve core 21, thus providing good protection. When venting is required, rotate the vent button 30 until the upper and lower positioning bars 40 are aligned, and the support rod 33 is also aligned with the abutment rod 25. Pulling up the vent button 30 will then complete the venting process in two simple actions. In summary, the vent button 30 protects the valve core 21, preventing accidental contact that could lead to leakage. The vent button 30 only contacts the valve core 21 at a specific angle, so accidental contact with the vent button 30 will hardly affect the valve core 21. When venting, simply pinch the vent valve and rotate it to the designated angle to pull out the valve core 21, making the operation convenient.

[0040] The above are merely embodiments of this application and are not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, improvements, or equivalent substitutions made within the spirit and principles of this application should be included within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
