Description

Technical Field

[0001] The utility model relates to the technical field of massage therapy, in particular to a rotating air positive and negative pressure massage device. Background Art

[0002] Massage is based on the theory of internal organs and meridians in Traditional Chinese Medicine (TCM), combined with Western medicine's anatomy and pathology. It uses manual manipulation to target specific areas of the human body to regulate physiological and pathological conditions and achieve therapeutic goals. Essentially, it is a physical therapy. Massage can be categorized as health massage, sports massage, and medical massage.

[0003] With the development of the times and advancements in technology, massage methods are no longer limited to manual massage. Massage devices are increasingly being used, such as existing massage chairs, foot massagers, and neck massagers. However, these massage devices do not target the affected area based on the dilation patterns of human blood vessels. Instead, they rely on mechanical direct contact pressure, which can cause significant damage to the skin and provide suboptimal massage results.

[0004] As a result, some compressed air massagers that perform indirect massage through inhalation and blowing have appeared on the market. The compressed air massager is a massage tool that can generate negative pressure through a pressure field generating mechanism, thereby producing an adsorption feeling, so as to adsorb and relax the skin muscles to relieve fatigue and soreness, and then promote blood circulation. However, the existing air positive and negative pressure massage devices usually use a piston to move back and forth in a straight line in a cavity to generate negative pressure. This movement method is relatively conventional, and the adsorption effect of the negative pressure generated by it is poor. Therefore, there is an urgent need to provide a new type of air positive and negative pressure massage device with a movement method that can generate negative pressure. Utility Model Content

[0050] In order to enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0051] Please also refer to Figures 1 to 8 , this embodiment provides a rotating air positive and negative pressure massage device, including a shell 100, a rotating shaft 200 and a driving device 300, a first receiving space 120 is provided in the shell 100, and at least one chamber is provided in the first receiving space 120, and an assembly port 124 is opened on the side wall of the chamber, and the shell 100 is provided with an air port 111, and the air port 111 is communicated with the chamber, the rotating shaft 200 can be rotatably installed at the assembly port 124, and at least one swinging member 210 is provided on the rotating shaft 200, and the swinging member 210 extends into the chamber, the driving device 300 is installed in the shell 100, and the driving device 300 is drivingly connected to one end of the rotating shaft 200, so that the driving device 300 drives the rotating shaft 200 to rotate and drives the outer wall of the swinging member 210 to swing back and forth along the inner wall of the chamber, thereby generating periodic alternating positive and negative pressure at the air port 111.

[0052] It can be seen that the rotary air positive and negative pressure massage device of this embodiment drives the rotating shaft 200 to rotate by the driving device 300 and drives the outer wall of the swinging member 210 to swing back and forth along the inner wall of the chamber, so that when the swinging member 210 swings back and forth, the volume of the air cavity enclosed by the swinging member 210 and the inner wall of the chamber becomes larger or smaller, thereby causing the air at the air port 111 to be sucked into the chamber or the air in the chamber to be exhaled to the air port 111 under pressure, and then periodically alternating positive and negative pressures can be generated at the air port 111 to achieve the effect of adsorbing and relaxing the skin muscles to relieve fatigue and soreness, and promote blood circulation. In addition, its positive and negative pressure movement generation method is relatively novel, the structure is simple, it is safe and reliable to use, and the adsorption effect is good.

[0053] In this embodiment, there is a gap between the swinging member 210 and the inner wall of the chamber, and the gap is not greater than 1 mm. Preferably, the gap is 0-0.1 mm. In this way, while the swinging member 210 can swing back and forth stably and reliably in the chamber, it can also ensure to a certain extent that the air pressure change in the chamber is sufficient to generate periodic alternating positive and negative pressures at the air port 111; and / or there is a gap between the rotating shaft 200 and the inner wall of the assembly port 124, and the gap is not greater than 1 mm. Preferably, the gap is 0-0.1 mm. In this way, while not affecting the smooth rotation of the rotating shaft 200 at the assembly port 124, it can also avoid most of the gas in the chamber from being quickly exchanged with the external environment through the gap to affect the positive and negative pressure effects generated at the air port 111.

[0054] Specifically, the rotating shaft 200 is roughly a cylindrical structure, and the opposite side walls of the assembly opening 124 are at least partially arc-shaped and smoothly transitioned, so that the rotating shaft 200 is more stable and smooth when rotating, avoiding structural interference that affects the normal operation of the rotating shaft 200. In addition, the rotating shaft 200 is at least partially accommodated in the chamber through the assembly opening 124, and the swinging member 210 is arranged on the partial surface of the rotating shaft 200 located in the chamber. The first receiving space 120 is roughly cylindrical, and the side wall of the chamber away from the rotating shaft 200 is at least partially an arc-shaped wall. The swinging member 210 swings back and forth along the arc-shaped wall of the chamber. In this way, when the rotating shaft 200 rotates and drives the swinging member 210 to swing back and forth, the mechanism runs more stably and smoothly, and the positive and negative pressure effects generated at the air port 111 are better.

[0055] In another embodiment, of course, the assembly port 124 can also be eliminated, and the rotating shaft 200 can be rotatably installed in the chamber, and the rotating shaft 200 is arranged adjacent to the first side wall of the chamber, and the swinging member 210 is extended toward the second side wall close to the chamber, and the second side wall of the chamber is at least partially an arc-shaped structure to ensure that the swinging member 210 is tightly fitted with the second side wall of the chamber when the swinging member 210 swings back and forth, and there is a gap between the rotating shaft 200 and the inner wall of the chamber and between the swinging member 210 and the inner wall of the chamber, and the gap is not greater than 1 mm. With such an arrangement, when the swinging member 210 swings back and forth in the chamber, it can also generate periodically alternating positive and negative pressures at the air port 111. It can be understood that this implementation method is also within the protection scope of the present utility model.

[0056] Furthermore, the swinging member 210 is a blade structure that protrudes and extends radially along the rotating shaft 200, and the plane where the blade is located is arranged roughly parallel to the central axis of the rotating shaft 200. In this way, when the rotating shaft 200 drives the blade to swing back and forth, the mechanism operates more stably and smoothly, the structure is simple and compact, and the processing difficulty and production cost are low.

[0057] In this embodiment, a groove 142 is provided at the bottom of the first receiving space 120, and the rotating shaft 200 is rotatably installed in the groove 142 through a bearing 220, and the outer ring of the bearing 220 is embedded in the groove 142, and the inner ring of the bearing 220 is sleeved on the rotating shaft 200. This arrangement allows the rotating shaft 200 to be rotatably installed through the bearing 220, further improving the stability and smoothness of the reciprocating swinging operation of the swinging member 210 driven by the rotating shaft 200, thereby achieving a better positive and negative pressure effect at the air port 111, and the bearing 220 is assembled through the groove 142, with a simple structure and convenient and quick assembly.

[0058] In one embodiment, there are multiple chambers, and the multiple chambers are distributed around the central axis of the rotating shaft 200. The assembly port 124 is located at the center of the first receiving space 120, and there are multiple swinging members 210, so that the multiple swinging members 210 are arranged in a one-to-one correspondence in the multiple chambers through the assembly port 124. A central chamber 130 is provided at the upper part of the first receiving space 120, and the central chamber 130 is connected to the air port 111. The multiple chambers are connected to the central chamber 130, so that the multiple chambers are connected to the air port 111 through the central chamber 130. In this way, the positive pressure and negative pressure generated by the multiple swinging members 210 swinging back and forth in the multiple chambers due to the rotation of the rotating shaft 200 are all concentrated in the central chamber 130, and stronger positive pressure and negative pressure can be generated at the air port 111, further improving the adsorption effect and strength.

[0059] Specifically, the interior of the chamber is divided into a compression chamber 121 and a connecting chamber 122 by the swinging member 210. The compression chamber 121 is connected to the air port 111. The connecting chamber 122 is provided with a connecting hole 151. The connecting chamber 122 is connected to the external environment through the connecting hole 151 to avoid the swinging member 210 swinging toward the connecting chamber 122 and being hindered by the air pressure in the connecting chamber 122. Among them, multiple compression chambers 121 and multiple connecting chambers 122 are alternately distributed one by one along the circumferential direction. In this way, when the rotating shaft 200 drives the swinging member 210 to swing back and forth, the multiple swinging members 210 can swing toward the compression chamber 121 or the connecting chamber 122 at the same time in each chamber, so that the multiple swinging members 210 can jointly generate the sum of positive pressure or negative pressure at the air port 111 through reciprocating swinging.

[0060] Among them, when the swinging member 210 swings toward the compression chamber 121, the air in the compression chamber 121 is pressurized and flows toward the air port 111, thereby generating a blowing effect at the air port 111; when the swinging member 210 swings away from the compression chamber 121, the volume between the compression chamber 121 and the swinging member 210 becomes larger, allowing the air at the air port 111 to flow toward the compression chamber 121, thereby generating an inhalation effect at the air port 111; the angle at which the swinging member 210 swings back and forth around the central axis of the rotating shaft 200 is greater than 20 degrees and less than 180 degrees, preferably greater than or equal to 30 degrees and less than or equal to 90, so that an inhalation and blowing effect is generated at the air port 111, thereby absorbing and relaxing the skin muscles to relieve fatigue and soreness.

[0061] Furthermore, the shell 100 includes a ring seat 140 and a cover body 150 that are engaged with each other. The ring seat 140 and the cover body 150 are fixed by screws 180 to form a first receiving space 120 between the ring seat 140 and the cover body 150, and a first sealing ring 125 is arranged between the ring seat 140 and the cover body 150 to ensure the sealing of the chamber through the first sealing ring 125. The connecting hole 151 is arranged on the cover body 150, and a through hole 141 is opened at the bottom of the ring seat 140. One end of the rotating shaft 200 is passed through the through hole 141, and the through hole 141 is coaxially connected with the groove 142. The aperture of the through hole 141 is smaller than the inner diameter of the groove 142, so that a limiting step for axially limiting the bearing 220 is formed between the groove 142 and the through hole 141.

[0062] Preferably, the bottom wall of the assembly opening 124 is connected to the groove 142 to facilitate the rotatable installation of the rotating shaft 200, and the gap between the upper end of the rotating shaft 200 and the inner surface of the cover body 150 and the gap between the top wall of the swinging member 210 and the inner surface of the cover body 150 are not greater than 1 mm. The upper part of the cover body 150 protrudes and extends to form an annular wall 152, and the upper part of the annular wall 152 is covered with a cavity cover 160 to form a centralized cavity 130 between the annular wall 152 and the cavity cover 160. A second sealing ring is provided between the annular wall 152 and the chamber cover 160 to ensure the sealing inside the concentrated chamber 130 through the second sealing ring. The top walls of the multiple compression chambers 121 are provided with air flow holes 131. The air flow holes 131 of the multiple compression chambers 121 are connected to the concentrated chamber 130. The upper part of the chamber cover 160 protrudes and extends to form an air pipe port 161. The air pipe port 161 is connected to the concentrated chamber 130, and the air pipe port 161 is connected to the cover body 110 to form an air port 111 at the mouth of the cover body 110.

[0063] In this embodiment, the driving device 300 includes a driving part 310, a cam 320, a sliding member 330 and a connecting rod 340. The lower part of the cam 320 is connected to the output shaft 311 of the driving part 310 to drive the cam 320 to rotate through the driving part 310. The sliding member 330 is slidably arranged in the shell 100. The sliding member 330 is movably connected to the upper part of the cam 320 so that the sliding member 330 can move back and forth in a straight line when the cam 320 rotates. One end of the connecting rod 340 is movably connected to the sliding member 330, and the other end of the connecting rod 340 is fixedly connected to one end of the rotating shaft 200 so that the linear reciprocating movement of the sliding member 330 is converted into the reciprocating swinging motion of the swinging member 210 on the rotating shaft 200 through the connecting rod 340.

[0064] Specifically, the driving part 310 can adopt a driving motor, and a guide structure is provided between the sliding member 330 and the housing 100 to guide the sliding member 330 to move back and forth through the guide structure. The sliding direction of the sliding member 330 is perpendicular to the rotation axis of the cam 320. The bottom of the sliding member 330 is provided with a strip groove 331, and the upper part of the cam 320 can be movably embedded in the strip groove 331. The length extension direction of the strip groove 331 is perpendicular to the sliding direction of the sliding member 330. , and the length extension direction of the strip groove 331 is perpendicular to the rotation axis of the cam 320. The upper part of the sliding member 330 protrudes and extends to form an axial end 332. One end of the connecting rod 340 is provided with a mouth structure 341. The axial end 332 of the sliding member 330 can be movably embedded in the mouth structure 341, and the mouth structure 341 is roughly an elliptical hole. The other end of the connecting rod 340 is provided with a connecting hole 342, so that one end of the rotating shaft 200 is inserted into the connecting hole 342 for fixing.

[0065] Furthermore, the shell 100 also includes a base 170, which is arranged at the lower part of the ring seat 140 to form a second receiving space 171 between the base 170 and the ring seat 140. The driving device 300 is installed on the base 170, and the guide structure is arranged between the base 170 and the sliding member 330. The guide structure includes at least one guide rod 350 and at least one guide hole. The guide hole is opened on the sliding member 330 so that the sliding member 330 can be slidably mounted on the guide rod 350 through the guide hole. In this way, when the driving part 310 drives the cam 320 to rotate, the upper part of the cam 320 moves in the strip groove 331, thereby driving the sliding member 330 to reciprocate along the guide rod 350, and through the active cooperation between the shaft end 332 of the sliding member 330 and the mouth structure 341 of the connecting rod 340, the swinging member 210 on the rotating shaft 200 is driven to swing back and forth.

[0066] In some embodiments, the first receiving space 120 is divided into at least two chambers by a partition 123, and the at least two chambers are arranged around the central axis of the rotating shaft 200. An assembly port 124 is opened on the partition 123. Preferably, the assembly port 124 is arranged at the center position of the partition 123.
