Technical Field

[0001] The utility model relates to the technical field of cupping devices, in particular to a glass cupping device with a micro pressure relief valve. Background Art

[0002] Cupping was called horn therapy in ancient times, also known as fire cupping and suction cup therapy. It uses cups as tools and utilizes combustion to expel the air in the cups, creating negative pressure, which is then adsorbed to the acupoints or the surface of the body where the cupping is to be done, producing stimulation, causing congestion and congestion of the skin at the site of cupping, in order to achieve the purpose of preventing and treating diseases. The cupping device uses a negative pressure source based on the principle of cupping to create negative pressure in the cup, thereby adsorbing it to the muscles.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] A glass cupping device with a micro pressure relief valve comprises a glass cup body 1, a vent 11 is provided at the top center of the glass cup body 1, a mounting plate 12 is fixed to the top of the glass cup body 1 by glue, a through hole 13 is provided at the top center of the mounting plate 12, and the through hole 13 is connected to the vent 11 for connecting to the outside world.

[0028] Specifically, a vacuum exhaust pipe 14 is fixed to the outer wall of the glass tank body 1 by glue, and the bottom end of the vacuum exhaust pipe 14 passes through the outer wall of the glass tank body 1 and passes into the inner cavity of the glass tank body 1, so as to introduce the air in the inner cavity of the glass tank body 1 into the vacuum pump.

[0029] Specifically, a valve 15 is installed on the vacuum exhaust pipe 14 to control whether air can pass through the vacuum exhaust pipe 14. A connector 16 is connected to the right end of the vacuum exhaust pipe 14 to connect to a vacuum pump.

[0030] Furthermore, the outer wall of the glass tank body 1 is provided with an anti-skid cover 17, which is made of rubber material and has an anti-skid effect.

[0031] It should be added that the outer wall of the anti-slip sleeve 17 is provided with a plurality of grooves 18, and the grooves 18 are evenly arranged at equal intervals to play an anti-slip role.

[0032] As a preferred embodiment of this embodiment, a pressure relief mechanism 2 is provided above the glass tank body 1, and the pressure relief mechanism 2 includes a movable plate 21 for driving a connecting rod 22 to move. The bottom of the movable plate 21 is fixedly connected to the connecting rod 22 by bolts for driving a mounting plate 23 to move.

[0033] Specifically, the bottom end of the connecting rod 22 is fixedly connected with a mounting plate 23 via bolts, so as to drive the sealing plug 24 to move.

[0034] Specifically, a sealing plug 24 is fixedly connected to the bottom of the mounting plate 23 by bolts, so as to seal the vent 11 and the through hole 13 .

[0035] Specifically, an upper sealing ring 25 and a lower sealing ring 26 are symmetrically sleeved on the circumferential outer wall of the sealing plug 24 near the upper and lower sides. The bottom of the upper sealing ring 25 is fixed to the top of the mounting plate 12 by glue, and the top of the lower sealing ring 26 is fixed to the top of the inner wall of the glass jar body 1 by glue, thereby achieving a sealing effect.

[0036] Specifically, the top of the mounting plate 12 is symmetrically fixedly connected with slide rods 27 by bolts near the left and right sides to limit the moving direction of the slide ring 28. The top of the slide rod 27 is fixedly connected with a limiting plate 271 by bolts to limit the highest position of the slide ring 28.

[0037] Specifically, a spring 272 is provided on the circumferential outer wall of the slide rod 27 to limit the position of the slide ring 28 .

[0041] When the negative pressure inside the glass tank body 1 is lower than the predetermined threshold, the two springs 272 begin to restore their initial lengths, thereby driving the two sliding rings 28 to move upward, thereby driving the moving plate 21 to move upward, thereby driving the connecting rod 22 and the mounting plate 23 to move upward, thereby driving the sealing plug 24 to move upward;

[0042] Until both springs 272 recover their initial lengths, the sealing plug 24 returns to its initial position and outside air can no longer be introduced into the vent 11 from the through hole 13 .
