[0057] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0058] Embodiment 1:

[0059] As Figures 1 - 8 shown, a massager described in this embodiment includes a housing 1, a pneumatic generating member 2, and a driving device. The housing 1 is provided with a receiving cavity 13 and at least two massage ports 14 arranged close to each other. The pneumatic generating member 2 is arranged in the receiving cavity 13. An inner cavity 20 is provided on the pneumatic generating member 2. A partition 21 is arranged in the inner cavity 20. The partition 21 divides the inner cavity 20 to form at least two mutually isolated pneumatic generating cavities 201. The openings 202 of the two pneumatic generating cavities 201 are respectively docked and communicated with the respective massage ports 14. The driving part of the driving device is connected to the partition 21.

[0060] Further, the driving device includes a motor 3 and a rotating member 4 mounted on the rotating shaft of the motor 3. The power and torque of the motor 3 are such that it can drive the rotating member 4 to rotate during use and has a relatively large power. The rotating member 4 can be a disc structure or a frustum structure with a smaller upper diameter than the lower diameter. The motor 3 and the rotating member 4 are both arranged in the receiving cavity 13. An eccentric member 41 is arranged on the rotating member 4. The eccentric member 41 is a columnar structure. The partition 21 is a flexible partition 21. The outer edge of the partition 21 is connected to the inner wall of the inner cavity 20. The pneumatic generating member 2 is provided with a jack 22 corresponding to the position of the slot 213 on the partition 21. At least a part of the eccentric member 41 passes through the jack 22 and is placed in the slot 213 of the partition 21. Therefore, when the motor 3 drives the rotating member 4 to rotate, the eccentric member 41 rotates around the central axis of the rotating member 4, so as to drive the partition 21 to deform in the inner cavity 20. Since the partition 21 is flexible, when the number of the pneumatic generating cavities 201 is two, when the eccentric member 41 moves, it can drive the partition 21 to deform, so that the distance between the opposite inner walls of one pneumatic generating cavity 201 decreases, and the distance between the opposite inner walls of the other pneumatic generating cavity 201 increases. When the number of the pneumatic generating cavities 201 is three or more, when the eccentric member 41 moves, it can drive the partition 21 to deform, so that the distance between the opposite inner walls of at least one pneumatic generating cavity 201 decreases, and the distance between the opposite inner walls of the remaining at least one pneumatic generating cavity 201 increases. The opposite inner walls of the pneumatic generating cavity 201 are respectively the outer wall of the partition 21 facing the pneumatic generating cavity 201 and the inner wall of the corresponding pneumatic generating cavity 201.

[0061] Preferably, the separator 21 includes a flexible connecting sleeve 211 and at least two flexible sheets 212 disposed on the outer sidewall of the flexible connecting sleeve 211. The outer edges of the flexible sheets 212 and the lower end of the flexible connecting sleeve 211 are both connected to the inner wall of the inner cavity 20, so as to form at least two mutually isolated air pressure generating chambers 201 in the inner cavity 20. The upper ends of the flexible sheets 212 are connected to each other. The upper and lower sections of each flexible connecting sleeve 211 form a slot 213 and a transition chamber 214 respectively, so that the slot 213 on the separator 21 is located in the middle of the inner cavity 20. The jack 22, the slot 213 and the transition chamber 214 are coaxially arranged, and there is a gap between the upper end of the flexible connecting sleeve 211 and the inner wall of the upper end of the inner cavity 20.

[0062] The slot, the transition chamber 214 and the jack are all of elongated structures. The length and width of the slot 213 < the length and width of the transition chamber 214, so that the wall thickness of the upper section of the flexible connecting sleeve 211 is greater than that of the lower section. The length and width of the jack 22 ≥ the length and width of the elongated transition chamber 214. This structure is mainly applicable to the case where the number of the air pressure generating chambers 201 is two. Correspondingly, the number of the flexible sheets 212 is two and they are oppositely arranged. The massage openings 14 also need to be arranged in two. Or

[0063] The slot, the transition chamber 214 and the jack are all of circular structures. The inner diameter of the slot 213 < the inner diameter of the transition chamber 214, so that the wall thickness of the upper section of the flexible connecting sleeve 211 is greater than that of the lower section. The inner diameter of the jack 22 ≥ the inner diameter of the transition chamber 214. This structure is mainly applicable to the case where the number of the air pressure generating chambers 201 is three or more. Correspondingly, the massage openings 14 also need to be arranged in three or more, and the number of the flexible sheets 212 is also arranged in three or more. Each flexible sheet 212 is generally arranged in an annular array, so that the included angle between two adjacent flexible sheets 212 is 5° - 120°.

[0064] Based on the above, the wall of the air pressure generating member 2 is made of a flexible material, and the walls of the separator 21, the flexible sheets 212 and the flexible connecting sleeve 211 are combined into an integral structure. So when the eccentric piece rotates around the central axis of the rotating member 4, the flexible connecting sleeve 211 can be deformed, thereby changing the volume sizes of at least two air pressure generating chambers 201. The air pressure generating member 2 with the integral structure is made of silica gel material.

[0065] In this embodiment, the rotating shaft of the motor 3 rotates, causing the eccentric member 41 to rotate around the central axis of the rotating member 4, which prompts the flexible connecting sleeve 211 of the partition body 21 to deform. As a result, the distance between the opposite inner walls of one of the two air pressure generating chambers 201 decreases, the distance between the opposite inner walls of the other air pressure generating chamber 201 increases or remains unchanged, or the distance between the opposite inner walls of at least one of the three air pressure generating chambers 201 decreases, and the distance between the opposite inner walls of the remaining at least one air pressure generating chamber 201 increases, so as to realize the volume reduction of at least one air pressure generating chamber 201 and the volume increase of the other or another part of the air pressure generating chambers 201. The gas in the at least one air pressure generating chamber 201 with reduced volume surges towards at least one massage port 14 connected thereto correspondingly, and the gas at the other or another part of the massage ports 14 surges into the air pressure generating chamber 201 with increased volume and corresponding connection, so as to form a pressure difference between at least two massage ports 14, and thus at least two massage ports 14 in contact with the human skin perform air stimulation massage on the human skin. Among them, as Figure 25 shown, the massage port 14 with increased air pressure forms air extrusion massage on the human skin, that is, the human skin produces slight depressions, and the massage port 14 with decreased air pressure forms negative pressure massage on the human skin, that is, the human skin produces slight protrusions towards the air pressure generating chamber direction.

[0066] Based on the above, when the partition body 21 between the two air pressure generating chambers 201 deforms, the middle part of the first wall of the partition body 21 facing one air pressure generating chamber 201 is in a convex state, while the middle part of the second wall of the partition body 21 facing the other air pressure generating chamber 201 is in a concave state, so as to reduce the volume of one air pressure generating chamber 201 and increase the volume of the other air pressure generating chamber 201. Or when the partition body 21 between the three air pressure generating chambers 201 deforms, the middle part of the first wall of the partition body 21 facing at least one air pressure generating chamber 201 is in a convex state, while the middle part of the second wall of the partition body 21 facing the remaining at least one air pressure generating chamber 201 is in a concave state, so as to reduce the volume of at least one air pressure generating chamber 201 and increase the volume of the remaining at least one air pressure generating chamber 201.

[0067] Further, the housing includes a rigid housing 11 and a flexible housing 12 wrapped around the outer peripheral wall of the rigid housing 11. At least two massage openings 14 are formed in the flexible housing 12. The accommodation cavity 13 is formed inside the rigid housing 11. A through hole 15 communicating with the accommodation cavity 13 is provided on the rigid housing 11. A first positioning body 16 at at least two massage openings 14 on the flexible housing 12 and a second positioning body 17 at at least two openings 202 on the air pressure generating member 2 are both inserted and positioned in the through hole 15, so that each of the openings 202 on the air pressure generating member 2 is respectively docked and communicated with the corresponding massage opening 14. The flexible housing 12 is made of a silicone material, and the rigid housing 11 is made of a plastic material. Moreover, the flexible housing 12 makes it more comfortable to hold the massager by hand, and makes the massage openings 14 flexible, thereby achieving a more comfortable use.

[0068] Preferably, the rigid housing 11 includes a first shell 111 and a second shell 112. Both the first shell 111 and the second shell 112 are made of a plastic material. An installation sleeve 5 is further provided in the accommodation cavity 13, and the installation sleeve 5 is also made of a plastic material. The air pressure generating member 2 and the motor 3 of the driving device are both positioned in the installation sleeve 5. The first shell 111 and the second shell 112 are bolted and fixedly connected after being assembled with each other. The positioning sleeve 18 on the first shell 111 is sleeved on the upper end of the air pressure generating member 2, and the convex ring 23 on the air pressure generating member 2 is clamped between the lower end surface of the positioning sleeve 18 on the first shell 111 and the upper end surface of the installation sleeve 5. Such a structural setting makes it convenient to install the air pressure generating member 2, the motor 3, the control board 7 and the battery 6. A control button 71 is provided on the control board 7, and the control button 71 corresponds to the position of the through hole 113 on the rigid housing 11, so as to facilitate the pressing of the control button 71 when pressing down on the flexible housing 12.

[0069] Embodiment 2:

[0070] As Figures 21 - 24As shown, a massager described in this embodiment has a general structure similar to that of the first embodiment, but differs from the first embodiment in that: the driving device includes a motor 3, the upper inner wall of the inner cavity 20 is a circular arc inner wall 203, the upper and lower ends of the separator 21 are respectively clearance-fitted or contact-fitted with the upper inner wall and the lower inner wall of the inner cavity 20, the lower end of the separator 21 is a cylinder 216 that maintains a clearance fit or contact fit with the lower inner wall of the inner cavity 20, the openings 202 of the two air pressure generating chambers 201 are arranged at the upper end of the inner cavity 20, the rotating shaft of the motor 3 is connected to the cylinder 216, wherein the separator 21 adopts a plate-like structure, and the inner cavity 20 can adopt a circular cavity, a fan-shaped cavity or a rectangular cavity with a circular arc inner wall 203, and the separator 21 is driven to swing back and forth by the rotation of the rotating shaft of the motor 3. The left and right reciprocating swing of the partition 21 is a slight reciprocating swing. When swinging, the partition 21 does not reach the opening 202 of the air pressure generating chamber 201, and the upper end of the partition 21 is displaced along the arc inner wall 203, and its lower end is a cylinder 216. Therefore, when the partition 21 swings, its lower end always conflicts with the lower inner wall of the inner cavity 20, so that under the left and right reciprocating swing of the partition 21, the volume of one air pressure generating chamber 201 is reduced and the volume of the other air pressure generating chamber 201 is increased. The gas in the air pressure generating chamber 201 with a reduced volume flows to a massage port 14 connected to it, and the gas at the other massage port 14 flows to the other air pressure generating chamber 201 with an increased volume, so that an air pressure difference is formed between the two massage ports, so that the two massage ports in contact with the human skin perform air stimulation massage on the human skin, wherein, Figure 25 As shown, the massage openings with increased air pressure form an air squeezing massage on the human skin, that is, the human skin produces a slight depression, and the massage openings with reduced air pressure form a negative pressure massage on the human skin, that is, the human skin produces a slight bulge toward the air pressure generating cavity.

[0071] Based on the above, the separator 21 is made of a hard material, and one end of the separator 21 rotates around the axis of one end of the area between the two air pressure generating chambers 201, so that in the two air pressure generating chambers 201, the first wall of the separator 21 facing one air pressure generating chamber 201 gradually approaches the first inner wall of the inner cavity to reduce the volume of one air pressure generating chamber 201, and the second wall of the separator 21 facing the other air pressure generating chamber 201 gradually moves away from the second inner wall of the inner cavity to increase the volume of the other air pressure generating chamber 201.

[0072] Among them, the power and torque of motor 3 adopt a motor with high power that can drive the separator 21 to rotate when in use. The motor shaft drives the separator 21 to swing back and forth left and right in forward and reverse rotation, and the forward and reverse rotation of the motor shaft is driven by the forward and reverse driving program built into the MCU chip to change the direction of the current delivered to the motor 3.

[0073] The air pressure generating member in this embodiment is made of a rigid material.

[0074] Embodiment Three:

[0075] A massager described in this embodiment has a general structure similar to that of Embodiment One or Embodiment Two, but is different from Embodiment One or Embodiment Two in that: as Figure 23 and Figure 24 shown, the driving device includes an electromagnetic coil 8, the partition 21 is a magnetic block, the inner cavity 20 is arranged in a straight cylinder structure, the magnetic block is located in the inner cavity 20 with a straight cylinder structure, and the outer peripheral wall of the magnetic block is in clearance fit or contact fit with the inner wall of the inner cavity 20 with a straight cylinder structure. The electromagnetic coil is wound around the outer peripheral wall of the inner cavity 20 with a straight cylinder structure and corresponds to the position of the magnetic block. The two openings 202 at both ends of the inner cavity 20 with a straight cylinder structure are respectively connected and communicated with each massage port 14 through pipelines. By continuously switching the positive and negative poles of the electromagnetic coil at a preset interval time when the electromagnetic coil is energized, the electromagnetic block makes a linear reciprocating displacement motion, and this reciprocating displacement motion is a micro displacement motion, so as to realize that in the two air pressure generating cavities 201, the volume of one air pressure generating cavity 201 decreases and the volume of the other air pressure generating cavity 201 increases. The gas in the air pressure generating cavity 201 with a reduced volume surges towards one massage port 14 corresponding to it, and the gas at the other massage port 14 surges into the other air pressure generating cavity 201 with an increased volume, so as to form an air pressure difference between the two massage ports, and thus the two massage ports in contact with the human skin perform air stimulation massage on the human skin. Among them, as Figure 25 shown, the massage port with increased air pressure forms air extrusion massage on the human skin, that is, the human skin produces slight depressions, and the massage port with reduced air pressure forms negative pressure massage on the human skin, that is, the human skin produces slight protrusions towards the air pressure generating cavity. Generally, the copper wire used for the electromagnetic coil is relatively thick to increase the flowing current and enhance the magnetic force, further driving the micro displacement motion of the magnetic block, and using the built-in current direction switching program in the MCU chip to change the current direction delivered to the electromagnetic coil 8. Therefore, when the current direction is constantly changed and the generated magnetic field is also constantly changed, the magnetic block is driven to make a reciprocating displacement motion, or

[0076] as Figure 25 and Figure 19As shown, the driving device includes an electromagnetic coil 8, the partition 21 is a magnetic block, the inner cavity 20 is a U-shaped cavity, the magnetic block is located in a straight cylinder cavity of the U-shaped cavity, and the outer peripheral wall of the magnetic block is in clearance fit or contact fit with the inner wall of the straight cylinder cavity of a U-shaped cavity. The electromagnetic coil is wound around the outer peripheral wall of the straight cylinder cavity of the U-shaped cavity and corresponds to the position of the magnetic block. The two openings 202 on the U-shaped cavity are respectively docked with the respective massage ports 14. By continuously switching the positive and negative poles of the electromagnetic coil at a preset interval time when the electromagnetic coil is energized, the electromagnetic block makes a linear reciprocating motion, and this reciprocating displacement motion is a micro-displacement motion, so as to realize that in the two air pressure generating cavities 201, the volume of one air pressure generating cavity 201 decreases and the volume of the other air pressure generating cavity 201 increases. The gas in the air pressure generating cavity 201 with the reduced volume surges towards one massage port 14 corresponding to it, and the gas at the other massage port 14 surges into the other air pressure generating cavity 201 with the increased volume, so as to form an air pressure difference between the two massage ports, and thus the two massage ports in contact with the human skin perform air-stimulating massage on the human skin. Among them, as Figure 25 shown, the massage port with increased air pressure forms air extrusion massage on the human skin, that is, the human skin produces slight depressions, and the massage port with decreased air pressure forms negative pressure massage on the human skin, that is, the human skin produces slight protrusions towards the air pressure generating cavity. Generally, the copper wire used in the electromagnetic coil is thicker to increase the flowing current and enhance the magnetic force, which can further drive the micro-displacement motion of the magnetic block, and use the built-in current direction switching program in the MCU chip to change the current direction delivered to the electromagnetic coil 8. When the current direction is constantly changing and the generated magnetic field is also constantly changing, the magnetic block is driven to make a reciprocating displacement motion, or

[0077] as Figure 20 shown, the driving device includes a telescopic driving mechanism, the inner cavity 20 is a U-shaped cavity, the partition 21 is located in a straight cylinder cavity of the U-shaped cavity, the telescopic driving mechanism is connected to the partition 21 through a linkage rod 215, the two openings 202 on the U-shaped cavity are respectively docked with the respective massage ports 14, the partition 21 adopts a block structure, and the telescopic driving mechanism drives the partition 21 to make a linear reciprocating motion, so as to realize that in the two air pressure generating cavities 201, the volume of one air pressure generating cavity 201 decreases and the volume of the other air pressure generating cavity 201 increases. The gas in the air pressure generating cavity 201 with the reduced volume surges towards one massage port 14 corresponding to it, and the gas at the other massage port 14 surges into the other air pressure generating cavity 201 with the increased volume, so as to form an air pressure difference between the two massage ports, and thus the two massage ports in contact with the human skin perform air-stimulating massage on the human skin. And as Figure 25As shown, the massage port with increased air pressure forms an air squeezing massage on the human skin, that is, the human skin produces a slight depression, and the massage port with reduced air pressure forms a negative pressure massage on the human skin, that is, the human skin produces a slight bulge toward the air pressure generating cavity; wherein the telescopic drive mechanism includes a motor, a rotating disk and a connecting rod, and the two ends of the connecting rod are respectively hinged with the eccentric position of the rotating disk and the connecting rod 215 on the separator 21, so that when the motor drives the rotating disk to rotate, the connecting rod and the connecting rod 215 are driven to move, so as to cause the separator 21 to make a linear reciprocating motion, and the telescopic drive mechanism can also adopt an electric push rod, adopting an electric push rod with larger power, and the forward and reverse rotation of the motor of the electric push rod is driven by the forward and reverse driving program built into the MCU chip to change the direction of the current delivered to the motor.

[0078] Preferably, the separator 21 of the block structure may be a circular block structure or a polygonal block structure, and the cross section of the inner cavity 20 may be a circular structure or a polygonal structure.

[0079] The power and torque of the motor are such that a motor with relatively large power can be used to drive the separator to move back and forth when in use.

[0080] The air pressure generating member in this embodiment is made of a hard material.
