1. Technical area

The technical field of this disclosure relates to the art of massage devices, and more particularly to a vacuum massage device and a massage stick thereof.

2. Description of the state of the art

With the industrial and economic development of society, people are now under more pressure for speed and efficiency in their lives. Combined with factors such as improper diet, overeating and lack of exercise, many problems have arisen due to diseases of the cardiovascular system or without any known cause. In order to fulfill various functions such as relaxing and healing the body, manufacturers in this field have developed various massage devices to meet the corresponding needs. Among these massage devices, a massage stick is particularly popular because it is inexpensive, easy to use and convenient to carry and operate.

The structure of a common massage stick mainly includes a stick body and a vibration unit installed in the stick body, which is used to drive the stick body to produce a corresponding vibration effect. When the stick body is in contact with a user's shoulders, neck or other body parts, it can massage them and relax the user's various body parts.

Although the common massage stick structure has vibration and massage effect, it cannot fully stimulate the user's skin and internal tissue during use, let alone improve skin activation and blood circulation. In addition, when force is applied to the stick body, blood flow congestion may occur on the user's skin and skin tissue. Therefore, the common massage stick does not satisfactorily meet the current requirements for massage sticks and massage devices.

US 2017/0036002 A1 discloses a method of promoting hair growth or stimulation in a subject using vacuum or suction. It comprises applying a handpiece assembly along a target area of the subject's skin surface where hair growth or stimulation is desired and applying at least one treatment material to the target area of the subject's skin surface, wherein the application of vacuum or suction promotes hair growth or stimulates hair formation.

WO 2004/066899 A2 discloses assemblies and packaging of multiple device facial and body treatment systems to enable adaptation of these systems for self-application and home use. In particular, a laptop-like set with multiple devices for facial and body treatment is described for "on-the-go" beauty treatments. In addition, a multiple device facial and body treatment system built into a dresser for home beauty care is presented. Other arrangements are also described.

US 2010/0036298 A1 discloses a massage head having a housing defining an inner chamber in which a skin fold is formed when placed on a patient's skin. The skin fold presses against the lower edges of the chamber, which is defined by two side walls and two transverse walls. A flap valve is arranged in each of the transverse walls and can be set in a pivoting movement so that the lower edges of the flaps in contact with the skin fold come closer to or move away from each other. The relative displacement of the flap valves is ensured by a motorized rotary cam mounted in the massage head. The cam defines a cam path which engages a component connected to the check valves and is capable of causing their pivoting movement.

In view of the above-mentioned disadvantages of the prior art, the discloser of the present disclosure has conducted extensive studies and experiments based on years of experience in the field and finally provided a feasible solution to overcome the disadvantages of the prior art.
