[0048] like Figures 1 to 8 As shown, a massage device for generating suction and a suction and exhaust drive device thereof according to a first preferred embodiment of the present invention is shown, wherein the massage device comprises a suction and exhaust drive device 1, a flexible massage housing 40, a fixed housing 50, a controller 60 and a power module 70. It can be understood that the suction and exhaust drive device 1 of the present invention is a drive component for driving the massage device. The massage device may include the controller 60 implemented as a circuit board, the power module 70, the flexible massage housing 40 and other massage components such as a vibration massager. The controller 60 and the power module 70 of the massage device may be electrically connected to a drive component 30 of the suction and exhaust drive device 1 to provide power supply to the drive component 30 and control the operation of the drive component 30. The flexible massage housing 40 may be sleeved outside the fixed housing 50 installed on the suction and exhaust drive device 1, and the flexible massage housing 40 may be implemented as a silicone sleeve or a rubber sleeve to be suitable for contacting with a human body part.

[0049] like Figure 2 and Figure 3As shown in the figure, the flexible massage housing 40 includes a housing body 41 and a head end housing 42, the head end housing 42 has an opening 43, the head end housing 42 and the housing body 41 are connected to form an inner cavity 44 therein for accommodating the air suction and discharge drive device 1, the fixed housing 50, the controller 60 and the power module 70. The opening 43 is connected to the inner cavity 44, and allows air to enter and exit the opening 43 under the driving action of the air suction and discharge drive device 1.

[0050] The shell body 41 and the head end shell 42 can be formed integrally and both made of flexible materials. Alternatively, the head end shell 42 can be made of flexible materials, while the shell body 41 can be made of flexible or rigid materials. In this embodiment, the shell body 41 and the head end shell 42 are integrally formed of the same flexible material such as silicone or rubber, such as by hot pressing, injection molding, etc. to form an integral structure with the inner cavity 44.

[0051] The fixed housing 50 is used to assemble the air suction and exhaust drive device 1, the controller 60 and the power module 70. The massage housing 40 is sleeved on the outside of the fixed housing 50, so that the fixed housing 50, the air suction and exhaust drive device 1, the controller 60 and the power module 70 are accommodated in the massage housing 40.

[0052] The power module 70 includes a rechargeable battery, such as a lithium battery, a lead-acid battery, a nickel-cadmium battery, a nickel-iron battery, a nickel-metal hydride battery, etc., to provide power supply for the controller 60 and the air suction and exhaust drive device 1. The controller 60 includes a control circuit board 61 and one or more switches 62. The switch 60, for example, can be a button, a knob, etc., which is exposed outside the massage housing 40 for user operation. In the example shown in the figure, the switch 62 is a button. The controller 60 can also control one or more control members 63, such as two control members 63, to respectively control the working power of the air suction and exhaust drive device 1.

[0053] like Figures 4 to 8Shown in the figure is an air suction and discharge drive device 1 for a massage device according to a first embodiment of the present invention, which includes a cavity 10, a plug body 20 movably arranged in the cavity 10, and a driving assembly 30 for driving the plug body 20, wherein the plug body 20 is arranged in the cavity 10 to form a first chamber 11 and a second chamber 12 located on opposite sides of the plug body 20, respectively, and when the driving assembly 30 drives the plug body 20 to reciprocate in the cavity 10, the size of the first chamber 11 and the second chamber 12 can be adjusted, so that the air pressure in the first chamber 11 can be adjusted, thereby providing the massage device with the required suction force.

[0054] The cavity 10 forms an opening 16 of the first chamber 11 on the top side, that is, the cavity 10 forms an open end on the top side. The flexible massage housing 40 of the massage device can be placed on the fixed housing 50 and its opening 43 corresponds to the open end of the cavity 10. It can be understood that in another variant embodiment, the cavity 10 can also include a top wall on the top side, and one or more through holes connected to the first chamber 11 are opened on the top wall.

[0055] In this embodiment, the plug body 20 has one or more vent holes 23, and the plug body 20 forms an annular assembly groove 24 on the bottom side, and an annular slightly movable valve sheet 25 is arranged in the assembly groove 24, which can be a flexible material, such as a silicone sheet, a rubber sheet or other materials. When the plug body 20 has a plurality of vent holes 23, these vent holes 23 are arranged along the circumferential direction, and the position of the valve sheet 25 can just correspond to these vent holes 23.

[0056] The cavity 10 is further formed with an exhaust hole 17 on its peripheral wall, which is connected to the second chamber 12. The vent hole 23 of the plug body 20 is adapted to cooperate with the valve plate 25 to connect the first chamber 11 and the second chamber 12 when the suction and discharge driving device 1 is in the process of deflation, so that the air further reaches the outside of the cavity 10 through the exhaust hole 17. An exhaust pipe 170 may be connected to the peripheral wall of the cavity 10 to form the exhaust hole 17.

[0057] More specifically, in this embodiment, reference is made to Figures 6 to 8As shown in , when the plug body 20 is driven to move downward, the flexible valve plate 25 in the assembly groove 24 is in close contact with the bottom side of the plug body 21, so that the vent hole 23 cannot be connected to the second chamber 12, so that the suction and release air drive device 1 generates the suction force required by the massage device. When the plug body 20 is driven to move upward, the valve plate 25 in the assembly groove 24 cannot be in close contact with the bottom side of the plug body 21, and a gap is generated. Part of the air in the first chamber 11 flows toward the opening 43 of the massage shell 40, and the other part enters the second chamber 12 from the vent hole 23, and is discharged through the exhaust hole 17, so that the suction and release air drive device 1 returns to the initial state.

[0058] In other words, in this embodiment, when the first chamber 11 is exhausted, not all the air is exhausted toward the opening 43 of the massage shell 40, so that the skin tissue or muscle sucked by the massage device will not be quickly loosened and separated from the opening 43, so that the massage device can maintain the state of sucking the user's body part at the opening 43 for as long as possible during the suction and exhaust cycle, thereby enhancing the effect of the suction massage.

[0059] The edge of the plug body 21 may also be formed with an annular positioning groove 22, which is used to accommodate a waterproof sealing ring 26, which is made of silicone, rubber or other materials, such as a flexible rubber ring or a flexible film, so as to enhance the air tightness while further preventing water entering the first chamber 11 from entering the second chamber 12.

[0060] In this embodiment, the chamber 10 may further include a partition layer 18 to form a third chamber 19 on the bottom side of the second chamber 12, and the driving rod 33 of the driving assembly 30 passes through the partition layer 18 to extend into the third chamber 19 and is connected to the transmission unit 32. In this way, the air entering the second chamber 12 is guided and discharged from the exhaust hole 17 on the peripheral wall of the chamber 10 without entering the third chamber 19.

[0061] In this embodiment, when the opening 43 of the massage shell 40 of the massage device is close to a human body part, the first chamber 11 can produce a change in air pressure under the action of the plug body 20. Specifically, because the first chamber 11 is connected to the opening 43, when the first chamber 11 inhales air, the air in the space between the opening 43 of the massage shell 40 and the first chamber 11 is sucked into the first chamber 11, and the skin tissue or muscle of the human body part adjacent to the opening 43 formed by the head end shell 42 of the massage shell 40 will be sucked. When the first chamber 11 is deflated, the skin tissue or muscle of the human body part adjacent to the opening 43 formed by the head end shell 42 of the massage shell 40 will be loosened. In this way, the massage device causes the first chamber 11 to produce an air pressure change through the air suction and discharge drive device 1, so that the air pressure changes at the corresponding position of the opening 43, thereby achieving a massage with suction on the human body part.

[0062] In this embodiment, the plug body 20 includes a plug body 21, which separates the first chamber 11 and the second chamber 12 and does not communicate with each other, so as to form an environment with adjustable air pressure in the first chamber 11 to generate suction. The cavity 10 can be columnar, so as to form a columnar space inside. Accordingly, the plug body 21 of the plug body 20 can implement a columnar sealing gasket.

[0063] The driving assembly 30 includes a driving motor 31, a transmission unit 32 and a driving rod 33, wherein the driving rod 33 is connected to the plug body 21 and is suitable for partially entering the second chamber 12. When the driving motor 31 is working, it drives the driving rod 33 to move back and forth periodically through the transmission unit 32, thereby further driving the plug body 20 to move back and forth periodically in the cavity 10, thereby adjusting the size of the first chamber 11 so that the suction and exhaust drive device 1 generates the suction force required by the massage device.

[0064] The drive rod 33 includes a mounting end 332 at one end adjacent to the plug body 20, and includes a connecting end 333 at the end adjacent to the drive motor 31 away from the plug body 20. The drive rod 33 forms a rod body 334 between the mounting end 332 and the connecting end 333. The mounting end 332 and the connecting end 333 are enlarged ends relative to the rod body 334. The mounting end 332 is connected to the bottom of the plug body 20 and forms the assembly groove 24. The connecting end 333 forms a connecting hole 331.

[0065] More specifically, in this embodiment, the driving motor 31 is a motor and includes a motor body 311 and an output shaft 312. The transmission unit 32 includes a first driving gear 321 and a second driving gear 322. The second driving gear 322 includes an eccentric shaft 3221. The first driving gear 321 is connected to the output shaft 312 of the driving motor 31. The second driving gear 322 is meshed with the first driving gear 321. The bottom end of the driving rod 33 has the connecting hole 331. The eccentric shaft 3221 of the second driving gear 322 is positioned in the connecting hole 331 of the driving rod 33. When the driving motor 31 is working, the first driving gear 321 connected to the output shaft 3221 is driven to rotate, thereby driving the second driving gear 322 to rotate, so that the eccentric shaft 3221 is displaced. The movement of the eccentric shaft 3221 drives the movement of the driving rod 33, thereby finally driving the plug body 20 to move in the cavity 10. When the first driving gear 321 and the second driving gear 322 complete a rotation cycle, the plug body 20 correspondingly generates a reciprocating movement cycle in the cavity 10 .

[0066] More specifically, when the drive motor 31 rotates, the output shaft 312 drives the first drive gear 321 and the second drive gear 322 to rotate, so as to drive the eccentric shaft 3221 to move toward the drive motor 31. The drive rod 33 moves synchronously with the eccentric shaft 3221 toward the drive motor 31, so that the plug body 20 moves in the direction of the drive motor 31, so that the volume of the first chamber 11 increases and gas is inhaled, thereby causing the air pressure in the space between the first chamber 11 and the opening 43 of the massage shell 40 to decrease, forming a negative pressure, thereby generating a suction massage on the human body parts.

[0067] When the output shaft 312 drives the first driving gear 321 and the second driving gear 322 to rotate and drives the eccentric shaft 3221 to move in a direction away from the driving motor 31, that is, the eccentric shaft 3221 reaches the bottom position and is driven by the second driving gear 322 to move upward, the driving rod 33 and the eccentric shaft 3221 move synchronously in a direction away from the driving motor 31, so that the plug body 20 moves in a direction away from the driving motor 31, so that the volume of the first chamber 11 is reduced and the gas is discharged, thereby causing the air pressure of the space between the first chamber 11 and the opening 43 of the massage housing 40 to increase and restore the initial air pressure. In this way, the above process is repeated, and the massage device can perform periodic suction massage on human body parts.

[0068] by Figures 6 to 8 According to the arrangement direction of the structural components shown in FIG, when the plug body 20 is driven to move downward, air enters the first chamber 11, so that the air suction and discharge driving device 1 generates the suction force required by the massage device. When the plug body 20 is driven to move upward, air is discharged from the first chamber 11, so that the air suction and discharge driving device 1 returns to the initial state.

[0069] In this embodiment, the fixed housing 50 includes a first housing portion 51 and a second housing portion 52 , which are assembled to form a space for accommodating the suction and discharge drive device 1 , the controller 60 and the power module 60 .

[0070] More specifically, for example, the fixed shell 50 includes a positioning element 53, which forms a positioning groove 531. In this embodiment, the positioning element 53 includes a positioning plate arranged on at least one of the first shell part 51 and the second shell part 52, and the positioning groove 531 is formed in the middle of the positioning element 53. The cavity 10 of the suction and discharge drive device 1 is engaged in the positioning groove 531 to be positioned. It can be understood that in this embodiment, the first shell part 51 and the second shell part 52 can both include similar structures of the positioning element 511 and the positioning groove 531, so that when the first shell part 51 and the second shell part 52 are buckled, the cavity 10 of the suction and discharge drive device 1 is positioned in the fixed groove formed by the two positioning grooves 531, and an assembly chamber 532 is formed in the fixed shell 50 to accommodate the cavity 10 of the suction and discharge drive device 1.

[0071] The fixed shell 50 further has an end chamber 54, which is located on opposite sides of the positioning element 53 implemented as a positioning plate from the assembly chamber 532, and the end of the end chamber 54 has an end hole 541, and the end hole 541 corresponds to the opening 43 of the massage shell 40. The end chamber 54 is connected to the first chamber 11 of the cavity 10 of the suction and discharge drive device 1.

[0072] The end chamber 54 of the fixed shell 50 forms an air pressure regulating chamber 501, which is connected to the first chamber 11 of the suction and discharge air drive device 1 and the end hole 541 of the fixed shell 50 and the opening 43 of the massage shell 40. Therefore, when the air pressure in the first chamber 11 in the cavity 10 is adjusted, the air pressure change is generated in the air pressure regulating chamber 501 accordingly, so that the massage device generates suction, thereby acting on the human body part.

[0073] The fixed shell 50 further forms a motor chamber 55 having a through hole 551 , and the drive motor 31 can be fixed and accommodated in the motor chamber 55 , and the output shaft 312 of the drive motor 31 extends out of the motor chamber 55 through the through hole 551 to be coupled to the transmission unit 32 .

[0074] The motor chamber 55 and the assembly chamber 531 are connected and intersected, the transmission unit 32 is correspondingly arranged at the intersection of the motor chamber 55 and the assembly chamber 531, and the fixed shell has a bending point 502 at the position corresponding to the transmission unit 32. In this way, the cavity 10 and the drive motor 31 of the suction and discharge drive device 1 are reasonably arranged, and the overall size is made more compact.

[0075] In addition, the outer surface of the fixed shell 50 may have a plurality of fixing grooves 58, and the inner surface of the massage shell 40 may be correspondingly formed with a plurality of fixing protrusions, so that each of the fixing protrusions is retained in the corresponding fixing groove 58, so that the massage shell 40 can be firmly retained in the fixed shell 50.

[0076] The fixed housing 50 further forms a controller accommodating slot 56 and a power accommodating slot 57 between the first housing portion 51 and the second housing portion 52 to accommodate the controller 56 and the power module 70 respectively.

[0077] like Figures 9 to 11 As shown, a massage device for generating suction and an air suction and exhaust drive device thereof according to a second preferred embodiment of the present invention are shown, wherein the massage device includes an air suction and exhaust drive device 1, a flexible massage shell 40, a fixed shell 50, a controller 60 and a power module 70.

[0078] In this embodiment, an air suction and discharge drive device 1 for a massage device includes a cavity 10, a plug 20 movably disposed in the cavity 10, and a drive assembly 30 for driving the plug 20, wherein the plug 20 is disposed in the cavity 10 to form a space in the cavity 10 into a first chamber 11 and a second chamber 12 located on opposite sides of the plug 20, respectively; when the drive assembly 30 drives the plug 20 to reciprocate in the cavity 10, the size of the first chamber 11 and the second chamber 12 can be adjusted, so that the air pressure in the first chamber 11 can be adjusted, thereby providing the massage device with the required suction force.

[0079] The cavity 10 forms an opening 16 of the first chamber 11 on the top side, that is, the cavity 10 forms an open end on the top side. The flexible massage shell 40 of the massage device can be placed on the fixed shell 50 and its opening 43 corresponds to the open end of the cavity 10. The plug body 20 has one or more vents 23, and the plug body 20 forms an annular assembly groove 24 on the bottom side, and an annular slightly movable valve plate 25 is arranged in the assembly groove 24, which can be a flexible material, such as a silicone sheet, a rubber sheet or other materials. The vent 23 of the plug body 20 is suitable for cooperating with the valve plate 25 to connect the first chamber 11 and the second chamber 12 when the air suction and discharge drive device 1 is in the air suction process.

[0080] In this embodiment, the cavity 10 may also include a partition layer 18 to form a third chamber 19 on the bottom side of the second chamber 12, and the driving rod 33 of the driving assembly 30 passes through the partition layer 18 to extend into the third chamber 19 and is connected to the transmission unit 32.

[0081] The cavity 10 is further formed with an exhaust hole 17 on the bottom side of the partition layer 18 located at the second chamber 12, which is connected to the second chamber 12. When the vent hole 23 of the plug body 20 can cooperate with the valve plate 25, the first chamber 11 and the second chamber 12 are connected when the suction and discharge driving device 1 is in the suction process, and the exhaust is further discharged through the exhaust hole 17 on the bottom side of the second chamber 12.

[0082] like Figures 9 to 11 As shown in FIG. 1 , in this embodiment, an exhaust pipe 170 is installed on the partition layer 18 , which forms the exhaust hole 17 to guide the air in the second chamber 12 into the assembly chamber 532 of the fixed shell 50 .

[0083] More specifically, in this embodiment, reference is made to Fig.11 As shown in , when the plug body 20 is driven to move downward, the flexible valve plate 25 in the assembly groove 24 is in close contact with the bottom side of the plug body 21, so that the vent hole 23 cannot be connected to the second chamber 12, so that the suction and release air drive device 1 generates the suction force required by the massage device. When the plug body 20 is driven to move upward, the valve plate 25 in the assembly groove 24 cannot be in close contact with the bottom side of the plug body 21, and a gap is generated. A part of the air in the first chamber 11 flows toward the opening 43 of the massage shell 40, and the other part enters the second chamber 12 from the vent hole 23, and is discharged through the exhaust hole 17 on the bottom side of the second chamber 12, so that the suction and release air drive device 1 returns to the initial state.

[0084] The edge of the plug body 21 may also be formed with an annular positioning groove 22, which is used to accommodate a waterproof sealing ring 26, which is made of silicone, rubber or other materials, such as a flexible rubber ring or a flexible film, so as to enhance the air tightness while further preventing water entering the first chamber 11 from entering the second chamber 12.

[0085] Accordingly, the present invention provides a method for producing suction massage, which comprises a periodic air-inhalation step and an air-release step, so as to produce massage on a contacted human body part.

[0086] More specifically, in the suction step, the transmission unit 32 is driven by the drive motor 31 to drive the drive rod 33 to drive the plug body 20 to move in the cavity 10 to increase the volume of the first chamber 11, so that the air in the air pressure regulating chamber 501 enters the first chamber 11, so that suction is generated at the opening 43 of the massage shell 40 to act on the human body part.

[0087] In the deflation step, the transmission unit 32 is driven by the drive motor 31 to drive the drive rod 33 to drive the plug body 20 to move in the cavity 10 to reduce the volume of the first chamber 11, so that a part of the air in the first chamber 11 enters the air chamber regulating chamber 501, and another part of the air flows through the vent hole 23 through the valve plate 25 into the second chamber 12, and is discharged from the exhaust hole 17 on the side or bottom.

[0088] In this embodiment of the present invention, the eccentric shaft 3221 of the transmission unit 32 is driven to move reciprocatingly by the drive motor 31, thereby realizing the reciprocating lifting and lowering motion of the drive rod 33, thereby further driving the plug body 20 to move reciprocatingly in the cavity 10.
