Abstract
Description
Technical area
[0001] The present utility model relates to the technical field of massage devices and in particular to an adjustable suction device. Background technology
[0002] Suction devices are a type of massage device that works on the principle of negative pressure to stimulate and massage body parts (such as the face) by simulating suction movements. In the cosmetic field, suction devices are often used for facial care to promote blood circulation, increase skin elasticity, reduce fine lines and wrinkles, and tighten facial contours. The suction movement can stimulate the production of collagen and elastic fibers under the skin, thereby improving skin quality.
[0003] Currently, many suction devices on the market have significant drawbacks. For example, structures that rely solely on a motor to reciprocate a suction cup have low suction power and an unobtrusive suction effect. Structures that use an air pump to generate the vacuum have too slow a change rate and essentially provide no pulsating suction effect, but only a constant suction effect, similar to a cupping effect, which is very uncomfortable for the user. Therefore, there is a need to improve current suction devices. Contents of this utility model
[0004] In view of the deficiencies of the prior art, the main objective of the present utility model is to provide an adjustable suction device which effectively solves the problems of low suction force or slow change rate in existing suction devices.
