Description

Technical Field

[0001] This utility model belongs to the field of cupping device technology, and specifically relates to a cupping device body. Background Technology

[0002] Cupping devices are instruments used for cupping therapy. Most cupping devices are one-piece cups. When used, they use fire or suction to create negative pressure, causing the cups to adhere to the body surface, resulting in local blood stasis. This achieves the effects of clearing the meridians, promoting blood circulation, reducing swelling and pain, and dispelling wind and cold, which are traditional Chinese medicine therapies.

[0003] Most cupping jars on the market today are one-piece structures, primarily made of glass, plastic, or silicone. For example, Chinese Utility Model Patent CN 202022186257.4 discloses a multi-functional cupping device, which includes a suction cup structure and a glass jar body. The suction cup structure is fixedly installed in a mounting hole at the top of the glass jar body, and a metal heat-insulating sleeve is fitted onto one end of the suction cup structure located within the glass jar body. The metal heat-insulating sleeve has air holes that connect the glass jar body and the suction cup structure. This utility model organically combines existing suction cups and glass cupping jars, giving one cupping device the functions of both. The metal heat-insulating sleeve effectively protects the suction cup structure and can also be used to add other functional components, such as medicinal cups, enriching the cupping functionality.

[0004] The above structure has a glass body. Glass is transparent, heat-resistant, and easy to clean, but it is prone to accidental breakage during use, which can easily lead to accidental injury to the user. Utility Model Content
