[0035] In the description of the embodiments of the present application, the technical terms "first", "second", and the like are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application.

[0037] The embodiments of the present application provide a massage device.

[0038] As Figures 1 to 7As shown, the massage device comprises a housing 10, a massage body 20 and a pump body 30. The housing 10 has a pressure cavity 11 inside, and the cavity opening of the pressure cavity 11 is formed at one end of the housing 10.

[0039] The massage body 20 is made of soft rubber material and has elasticity. The massage body 20 is arranged in the pressure cavity 11 and seals the cavity opening of the pressure cavity 11. The massage body 20 has a massage cavity 21 inside, and the cavity opening of the massage cavity 21 is exposed to the outside of the housing 10. There is a space between the outer wall of the massage body 20 and the cavity wall of the pressure cavity 11, forming an air pressure space 12.

[0040] The pump body 30 is arranged in the housing 10 and connected to the pressure cavity 11. The pump body 30 is used for gas exchange with the air pressure space 12. Specifically, the pump body 30 can output gas to the air pressure space 12 to increase the pressure of the air pressure space 12 and make the massage body 20 contract inward.

[0041] When using the massage device provided by the present application, the user can insert a body part into the massage cavity 21, and the pump body 30 can output gas to the air pressure space 12, causing the massage body 20 to contract inward by air pressure, so that the internal space of the massage cavity 21 can be adapted to the body part, improving the fit between the inner wall of the massage cavity 21 and the body part, and improving the massage effect.

[0042] In this embodiment, the pump body 30 is an air bag 31, which has deformation ability and is hollow inside.

[0043] The housing 10 is provided with a gas channel, one end of which is communicated with the pressure cavity 11, and the other end of which is connected to the air bag 31. The housing 10 is also provided with a first one-way valve 13 and a second one-way valve 14, both of which are arranged in the gas channel, and the second one-way valve 14 and the first one-way valve 13 are spaced apart along the gas conveying direction of the air bag 31.

[0044] When the air bag 31 is compressed and deformed, the first one-way valve 13 allows the gas in the air bag 31 to enter the air pressure space 12 through the gas channel; when the air bag 31 restores its deformation, the second one-way valve 14 allows the gas outside the pressure cavity 11 to enter the inside of the air bag 31 through the gas channel.

[0045] It can be understood that when the air bag 31 is pressed, it can be compressed and deformed, and the gas in the air bag 31 can enter the air pressure space 12, and after stopping pressing the air bag 31, the air bag 31 can restore its deformation and be filled with gas again.

[0046] It is worth noting that, under the action of the first one-way valve 13, the gas in the gas pressure space 12 cannot flow back to the air bag 31 through the gas passage. Under the action of the second one-way valve 14, the gas output by the air bag 31 when compressed and deformed can only enter the gas pressure space 12. In this way, by reciprocally pressing the air bag 31, the air bag 31 can continuously output gas to the gas pressure space 12, so that the massage body 20 is inwardly retracted.

[0047] In some embodiments, the shell 10 comprises a first shell 40 and a second shell 50, the pressure cavity 11 is arranged in the first shell 40, and the massage body 20 and the air bag 31 are arranged at two ends of the first shell 40, respectively.

[0048] The second shell 50 is arranged on the end of the first shell 40 close to the air bag 31, and the second shell 50 is in sliding connection with the first shell 40, and the air bag 31 is accommodated in the second shell 50.

[0049] When the second shell 50 moves towards the first shell 40, i.e. the second shell 50 moves along the X1 direction in the figure, the second shell 50 presses the air bag 31, so that the air bag 31 is compressed and deformed.

[0050] When the second shell 50 moves away from the first shell 40, i.e. the second shell 50 moves along the X2 direction in the figure, the air bag 31 recovers deformation.

[0051] It can be understood that the first shell 40 supports and fixes the massage body 20, and the second shell 50 shields and protects the air bag 31. Moreover, by reciprocally sliding between the first shell 40 and the second shell 50, the air bag 31 can be reciprocally pressed, so that the massage body 20 is inwardly retracted.

[0052] In some embodiments, the first shell 40 has a circular cross section, the inside of the first shell 40 forms the pressure cavity 11, and the pressure cavity 11 forms a cavity opening at the end of the first shell 40 away from the second shell 50.

[0053] The inside of the cavity opening of the pressure cavity 11 is provided with a clamping jaw 15. The massage body 20 is provided with a clamping groove 22 at the end of the cavity opening close to the massage cavity 21, and the clamping groove 22 is distributed around the outside of the massage body 20. The massage body 20 blocks the cavity opening of the pressure cavity 11, and the clamping jaw 15 is embedded in the clamping groove 22.

[0054] For example, the clamping jaw 15 is arranged to extend towards the center of the pressure cavity 11, and the clamping jaw 15 is distributed along the cavity wall of the pressure cavity 11.

[0055] The massage body 20 has a fixed part and a main body part. The fixed part is located at the cavity opening of the pressure cavity 11, and the main body part is located inside the pressure cavity 11. The fixed part and the main body part are integrally formed. The maximum outer diameter of the fixed part is greater than the inner diameter of the cavity opening of the pressure cavity 11, and the outer side of the fixed part is recessed to form a clamping groove 22. The fixed part is sealed at the cavity opening of the pressure cavity 11, and the fixed part is fixed to the clamping jaw 15 through the clamping groove 22. The inner wall of the main body part is provided with massage protrusions. The maximum outer diameter of the main body part is smaller than the inner diameter of the pressure cavity 11, so that there is a gap between the outer wall of the main body part and the cavity wall of the pressure cavity 11.

[0056] It can be understood that the main body part forms the air pressure space 12 through the gap between the main body part and the cavity wall of the pressure cavity 11, and can be inwardly retracted under the condition that the pressure in the air pressure space 12 increases. The fixed part seals the cavity opening of the pressure cavity 11 on the one hand, so that the pressure in the air pressure space 12 is more easily increased, and on the other hand, the fixed part can support and fix the main body part.

[0057] In some embodiments, the first shell 40 is further provided with an end cover away from the second shell 50. The end cover is detachably connected to the first shell 40, and the detachable connection mode can be interference fit, clamping fit, magnetic attraction fit, etc.

[0058] In this way, when massage is not needed, the user can fix the end cover to the first shell 40 to shield and protect the massage body 20. When massage is needed, the user can detach the end cover from the first shell 40.

[0059] In some embodiments, the first shell 40 is provided with a mounting seat 60 away from the pressure cavity 11, and the mounting seat 60 is used to be connected with the air bag 31. An intermediate space 41 is provided between the first shell 40 and the mounting seat 60, and the second one-way valve 14 is arranged in the intermediate space 41. The connection between the second shell 50 and the first shell 40 has an assembly gap, so that the intermediate space 41 is in communication with the external space of the massage device.

[0060] In this way, when the air bag 31 recovers deformation, the gas outside the first shell 40 can enter the intermediate space 41 through the assembly gap, and then enter the inside of the air bag 31 through the second one-way valve 14.

[0061] For example, one side of the first shell 40 facing the mounting seat 60 is provided with a fixing hole 42. The first one-way valve 13 is embedded and fixed in the fixing hole 42.

[0062] The first one-way valve 13 has an air inlet end and an air outlet end. The air inlet end of the first one-way valve 13 is arranged towards the mounting seat 60, and the air outlet end of the first one-way valve 13 penetrates the cavity bottom of the pressure cavity 11 and enters the air pressure space 12.

[0063] The mounting base 60 is provided with a first connecting pipe 61 on the side facing the first housing 40, which is located in the intermediate space 41. The first connecting pipe 61 is connected to the gas inlet end of the first one-way valve 13. The second one-way valve 14 has a gas inlet end and a gas outlet end, the gas inlet end of the second one-way valve 14 is exposed to the intermediate space 41, and the gas outlet end of the second one-way valve 14 is connected to the first connecting pipe 61.

[0064] The mounting base 60 is provided with a mounting hole 62 on the side away from the first housing 40, which is used for mounting the air bag 31. The second connecting pipe 63 is arranged in the mounting hole 62, which is connected to the air bag 31, and the first connecting pipe 61 and the second connecting pipe 63 are connected in communication.

[0065] It can be understood that the gas passage is formed between the interior of the first one-way valve 13, the interior of the second one-way valve 14, the first connecting pipe 61 and the second connecting pipe 63.

[0066] When the second housing 50 moves towards the first housing 40, the air bag 31 is compressed and deformed, and the gas in the air bag 31 sequentially passes through the second connecting pipe 63, the first connecting pipe 61, the first one-way valve 13, and enters the gas pressure space 12.

[0067] When the second housing 50 moves away from the first housing 40, the air bag 31 recovers and deforms, and the gas outside the first housing 40 and the second housing 50 enters the intermediate space 41 through the assembly gap, and sequentially passes through the second one-way valve 14, the first connecting pipe 61, the second connecting pipe 63, and enters the interior of the air bag 31, so that the interior of the air bag 31 can be refilled with gas.

[0068] In some embodiments, the interior of the second housing 50 forms a receiving cavity 51, the cavity opening of the receiving cavity 51 is formed at the end of the second housing 50 close to the first housing 40, and the first housing 40 is partially received in the receiving cavity 51.

[0069] The inside of the cavity opening of the receiving cavity 51 is provided with a limiting protrusion 52, which protrudes towards the center of the receiving cavity 51, and the limiting protrusion 52 is distributed along the cavity wall of the receiving cavity 51. The end of the first housing 40 close to the second housing 50 is provided with a sliding groove 43, and the limiting protrusion 52 is arranged in the sliding groove 43.

[0070] When the first housing 40 and the second housing 50 move relative to each other, the limiting protrusion 52 slides in the sliding groove 43. It can be understood that the sliding groove 43 limits the sliding distance of the limiting protrusion 52, thereby limiting the sliding stroke between the first housing 40 and the second housing 50, and preventing the second housing 50 from completely separating from the first housing 40 during sliding.

[0071] In some embodiments, a gap is left between the bottom wall of the sliding groove and the surface of the limiting protrusion 52, which can prevent the second shell 50 from being stuck with the first shell 40 during the sliding process, and form an assembly gap, so that the gas outside the first shell 40 and the second shell 50 can enter the intermediate space 41.

[0072] In some embodiments, the cavity wall of the accommodating cavity 51 is further provided with a guide block. The surface of the first shell 40 and the mounting seat 60 is provided with a guide groove, and the guide block is arranged in the guide groove. When the first shell 40 and the second shell 50 move relative to each other, the guide block slides in the guide groove, which plays a guiding and limiting role and improves the sliding stability.

[0073] In some embodiments, the second shell 50 is provided with a pressing block 53, and the side of the pressing block 53 facing the air bag 31 is provided with an arc-shaped protrusion 531 for extruding the air bag 31. For example, the pressing block 53 is clamped and fixed in the second shell 50, the arc-shaped protrusion 531 is formed on the surface of the pressing block 53 in an arc shape, and the arc-shaped protrusion 531 is arranged opposite to the position of the mounting hole 62.

[0074] In this way, when the second shell 50 moves towards the first shell 40, the second shell 50 drives the pressing block 53 to move towards the air bag 31, so that the arc-shaped protrusion 531 extrudes the air bag 31, and the air bag 31 is compressed to form a direction into the mounting hole 62. By arranging the arc-shaped protrusion 531, the extrusion effect of the air bag 31 can be improved, and the efficiency of gas output can be improved.

[0075] In some embodiments, the air bag 31 is elastic. When the air bag 31 restores the deformation, the air bag 31 drives the second shell 50 to move away from the first shell 40.

[0076] For example, the air bag 31 has a whole drop shape, and the air bag 31 has a spherical part and a sleeve part, which are integrally formed. The sleeve part enters the mounting hole 62 and is sleeved with the second connecting pipe 63, so that the second connecting pipe 63 is connected with the air bag 31. The spherical part is used to contact the arc-shaped protrusion 531.

[0077] By using the elasticity of the air bag 31, when the pressing block 53 extrudes the air bag 31, the air bag 31 can be compressed and deformed. After the pressing block 53 stops extruding the air bag 31, the air bag 31 automatically restores the deformation and is full of gas again. In this process, the air bag 31 can also drive the pressing block 53 to move, so that the second shell 50 automatically moves away from the first shell 40, which is convenient for operation.

[0078] In some embodiments, a spring member 54 is arranged in the second shell 50, one end of the spring member 54 abutting against the mounting base 60, and the other end of the spring member 54 abutting against the pressing block 53. After the pressing block 53 stops pressing the air bag 31, the spring member 54 can push the pressing block 53 to move, so that the second shell 50 is automatically moved away from the first shell 40, prompting the air bag 31 to quickly recover the deformation and be re-filled with gas.

[0079] In some embodiments, the massage device further comprises a pressure relief valve 70 arranged in the shell 10, and the pressure relief valve 70 is communicated with the pressure chamber 11, and the pressure relief valve 70 can output the gas in the pressure chamber 11 to the outside of the pressure chamber 11.

[0080] In this way, the pressure in the gas pressure space 12 can be reduced by the pressure relief valve 70, so that the massage body 20 expands outward, facilitating the user to adjust the fitting degree of the massage body 20 and the body part.

[0081] In some embodiments, the side of the second shell 50 is provided with an opening 55, and the opening 55 penetrates through the inside and outside of the second shell 50.

[0082] The pressure relief valve 70 comprises a valve seat 71, a valve core 72, a block 73 and a spring member 74. The valve seat 71 is fixed to the side of the pressing block 53 close to the opening 55. The valve seat 71 has a pressure relief chamber inside, and the pressure relief chamber is communicated with the pressure chamber 11. The valve seat 71 is provided with a through hole communicating with the pressure relief chamber, and the through hole corresponds to the opening 55.

[0083] The valve core 72 is arranged in the through hole and the opening 55. The block 73 is arranged in the valve seat 71, and the block 73 is distributed around the circumferential side of the valve core 72. The spring member 74 is arranged in the valve seat 71, and abuts against the block 73.

[0084] When the valve core 72 is in a non-pressed state, the block 73 abuts against the inner wall of the valve seat 71 and blocks the through hole under the action of the spring member 74. When the valve core 72 is in a pressed state, a gap is left between the block 73 and the through hole, so that the inside of the pressure relief chamber is communicated with the outside of the pressure relief chamber.

[0085] For example, the side of the pressing block 53 close to the opening 55 is provided with a stepped portion 532, and the valve seat 71 is fixed to the stepped portion 532 by bolting. The side of the valve seat 71 close to the first shell 40 is provided with a communication pipe, and the communication pipe is arranged in the pressing block 53. The side of the first shell 40 close to the mounting base 60 is provided with a butt joint pipe, and the butt joint pipe is communicated with the gas pressure space 12, and the butt joint pipe and the communication pipe are connected by a hose.

[0086] A sealing ring 75 is provided inside the valve seat 71. The sealing ring 75 is fitted onto the valve core 72, and the sealing ring 75 is located on the side of the stop block 73 facing the through hole. The elastic element 74 is a compression spring, which is located inside the valve seat 71. The elastic element 74 is fitted onto the end of the valve core 72 away from the sealing ring 75. One end of the elastic element 74 abuts against the side of the stop block 73 away from the sealing ring 75, and the other end of the elastic element 74 abuts against the bottom of the valve seat 71. A pressure cover 76 is provided on the end of the valve core 72 exposed through the through hole, and part of the pressure cover 76 is exposed through the opening 55.

[0087] When depressurization is not required, the user does not need to press the pressure cover 76. At this time, the elastic element 74 abuts against the stop block 73, and the stop block 73 seals the perforation through the sealing ring 75 so that the depressurization chamber and the receiving chamber 51 are not connected, thereby reducing gas leakage in the air pressure space 12.

[0088] When pressure relief is required, the user can press the pressure cover 76, causing it to move towards the inlet opening 55, which in turn moves the valve core 72. At this time, the stop block 73 compresses the elastic element 74, and a gap is formed between the sealing ring 75 and the through hole, so that the pressure relief chamber and the receiving chamber 51 are connected. The gas in the pressure space 12 can flow through the pressure relief chamber to the receiving chamber 51, while the gas in the receiving chamber 51 can leak out of the second outer casing 50 through the gap between the pressure cover 76 and the opening 55, thus achieving the pressure relief effect.

[0089] like Figure 8 As shown, the difference between this embodiment and the first embodiment is that the pump body 30 is an electric air pump 32, which is fixed to the housing 10, and its outlet is connected to the pressure chamber 11. For example, the electric air pump 32 is fixed to the end of the first housing 40 away from the opening of the pressure chamber 11. A solenoid valve is also provided at the end of the first housing 40 near the electric air pump 32, and the outlet of the electric air pump 32 is connected to the pressure chamber 11 through the solenoid valve. The solenoid valve can be used to control the gas flow between the electric air pump 32 and the pressure chamber 11.
