[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the motor, the first magnetic ring and the second magnetic ring, etc., when the motor drives the square rod to rotate, the iron moving ring rotates synchronously, and the third tooth fixedly connected to the iron moving ring will wave and move the first tooth. When the third tooth rotates a certain angle, the first tooth is no longer subjected to thrust. Under the force of the center of gravity of the rotating rod, the rotating rod begins to swing, and the swing amplitude gradually decreases. When the third tooth rotates one circle, it pushes the first tooth to rotate again, achieving a repeated swing effect. Moreover, under the action of the connecting rod, multiple rotating rods rotate synchronously, so that the water in the cupping bottle is drained faster. If the cupping bottle is not made of glass and can withstand greater vibration, the iron moving ring can be manually pushed to separate the iron moving ring from the attraction of the second magnetic ring and move to the right end to be attracted by the first magnetic ring. At this time, the second tooth and the first tooth are in the same plane, and the second tooth is longer, so that the swing amplitude of the rotating rod is larger and the water can be drained faster.

[0017] 2. Through the first spring, push rod motor and cross bar, after the cupping bottle is placed, the push rod motor is started, and the push rod motor drives the cross bar to move downward, so that the cupping bottle moves into the medicine liquid. Under the action of the vibration motor, the medicine liquid vibrates rapidly to clean the dirt in the cup. After the cleaning is completed, the push rod motor drives the cross bar to move upward. If the first tooth collides with the second tooth or the third tooth at this time, the cross bar compresses the first spring and stops rising until the iron moving ring rotates a certain angle so that the first tooth is staggered, and then continues to rise, ensuring the rationality of the equipment and increasing the stability of use.

[0035] Reference Figure 1-6 as well as Figure 7-10The working principle and operation steps of the second embodiment are basically the same as those of the first embodiment, and the main difference is that an auxiliary device is fixedly provided on the bottom side wall of the box body 1, and the auxiliary device includes a water pump 33 fixedly connected to the bottom side wall of the box body 1, and the water outlet of the water pump 33 is fixedly connected to a plurality of branch pipes 34, and the upper side wall of the branch pipe 34 is fixedly connected to a plurality of rotary joints 35, and the plurality of rotary joints 35 are respectively located below the tray 19, and the upper part of the plurality of rotary joints 35 is rotatably connected to a rotary water pipe 36, and the side wall of the rotary water pipe 36 is provided with a plurality of A water spray hole 38 is set obliquely, and a perforation 37 is opened on the upper side wall of the tray 19, and the perforation 37 is located directly above the rotating water pipe 36.

[0036] In the present invention, first, the cupping bottle is clamped between the two half rings 11, and the mouth of the cup is clamped above the ultraviolet light bulb 20. At this time, the center of gravity of the cupping bottle is below the rotating rod 8. After the cupping bottle is placed, the push rod motor 3 is started, and the push rod motor 3 drives the cross bar 4 to move downward, so that the cupping bottle moves into the medicine liquid. Under the action of the vibration motor 2, the medicine liquid vibrates rapidly to clean the dirt in the cup. After the cleaning is completed, the push rod motor 3 drives the cross bar 4 to move upward. If the first tooth 21 collides with the second tooth 28 or the third tooth 29 at this time, the cross bar 4 compresses the first spring 6 and stops rising until the iron moving ring 27 rotates a certain angle so that the first tooth 21 is staggered, and then continues to rise, ensuring the rationality of the equipment and increasing the stability of use. After the cupping bottle rises, it begins to drain. At this time, when the motor 23 drives the square rod 24 to rotate, the iron moving ring 27 rotates synchronously, and the iron moving ring 2 The third tooth 29 fixedly connected to the handle 7 will wave-motivate the first tooth 21. When the third tooth 29 rotates a certain angle, the first tooth 21 is no longer subjected to thrust. Under the force of the center of gravity of the rotating rod 8, the rotating rod 8 begins to swing, and the swing amplitude gradually decreases. When the third tooth 29 rotates one circle, it pushes the first tooth 21 to rotate again, achieving a repeated swinging effect. Moreover, under the action of the connecting rod 32, multiple rotating rods 8 rotate synchronously, so that the water in the cupping bottle is drained faster. If the cupping bottle is not made of glass and can withstand greater vibration, the iron moving ring 27 can be manually pushed to disengage the iron moving ring 27 from the attraction of the second magnetic ring 25 and move to the right end to attract the first magnetic ring 26. At this time, the second tooth 28 is in the same plane as the first tooth 21, and the second tooth 28 is longer, so that the swing amplitude of the rotating rod 8 is larger and the water can be drained faster.
