In addition, the terms "first", "second" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0044] Unless otherwise defined, all technical and scientific terms used in the specification are the same as those commonly understood by those skilled 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. The term "and / or" used in the specification includes any and all combinations of one or more related listed items.

[0045] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict between them.

[0046] As Figures 1-3 shown, the massage device 100 provided by one of the embodiments of the present application includes at least one massage assembly 10, a transmission assembly 20 and a driver 30. The transmission assembly 20 is connected to the at least one massage assembly 10, and the driver 30 is connected to the transmission assembly 20. The driver 30 transmits the rotating force to the massage assembly 10 through the transmission assembly 20, so that the massage assembly 10 can rotate around the central axis of the massage assembly 10, thereby achieving the purpose of the massage assembly 10 massaging the human body.

[0047] As Figure 4As shown, for the massage assembly 10, it comprises a pneumatic telescopic mechanism 1 and a massage head 2, the massage head 2 is installed on the pneumatic telescopic mechanism 1, the pneumatic telescopic mechanism 1 is connectable with an external air source, and the pneumatic telescopic mechanism 1 is used to drive the massage head 2 to move along a first axis when the external air source is inflated or deflated, so that the massage head 2 massages the human body. In some embodiments, the first axis is the central axis of the pneumatic telescopic mechanism. In other embodiments, the first axis is an axis parallel to and spaced apart from the central axis of the massage assembly 10.

[0048] In some embodiments, as shown in Figure 4 With Figure 5 As shown, the pneumatic telescopic mechanism 1 comprises a plurality of telescopic rods 12 which can be slid in sequence and are sealed to each other, and a sleeve 14 for connecting the external air source, the plurality of telescopic rods 12 are connected to the sleeve 14, and the massage head 2 is connected to the end of the innermost telescopic rod 12 of the plurality of telescopic rods 12. In this way, when the external air source introduces gas into the sleeve 14, as the gas pressure in the sleeve 14 increases, the gas will push the plurality of telescopic rods 12 to extend relative to the sleeve 14 to achieve the movement of the massage head 2. The first axis is the central axis of the plurality of telescopic rods 12 of the pneumatic telescopic mechanism 1.

[0049] It can be understood that the number of the plurality of telescopic rods 12 can be two telescopic rods 12, three telescopic rods 12, or more than three telescopic rods 12, which can be set as needed. And the plurality of telescopic rods 12 are hollow, that is, the opposite ends of each telescopic rod 12 are open and not closed. In order to stabilize the telescopic rods 12 and not to deviate, the plurality of telescopic rods 12 are preferably made of hard material, such as hard plastic or metal.

[0050] For the convenience of description, the outermost telescopic rod 12 of the plurality of telescopic rods 12 is named as the first telescopic rod 121, the innermost telescopic rod 12 of the plurality of telescopic rods 12 is named as the last telescopic rod 123, and the intermediate telescopic rod 122 is located between the first telescopic rod 121 and the last telescopic rod 123. The number of the intermediate telescopic rod 122 can be zero, one, two or more, which can be set as needed.

[0051] In some embodiments, the plurality of telescopic rods 12 can be divided into the first telescopic rod 121 and the last telescopic rod 123, and the intermediate telescopic rod 122 is omitted, that is, there is no intermediate telescopic rod 122, and the first telescopic rod 121 is sleeved on the last telescopic rod 123.

[0052] In some embodiments, as shown in Figure 5 With Figure 6As shown, the multi-section telescopic rod 12 can be divided into a first telescopic rod 121, a middle telescopic rod 122, and a last telescopic rod 123. The middle telescopic rod 122 is sleeved on the last telescopic rod 123, the first telescopic rod 121 is sleeved on the middle telescopic rod 122, and the last telescopic rod 123 is connected to the massage head 2. That is, the last telescopic rod 123 is the innermost telescopic rod 12 in the multi-section telescopic rod 12. The sleeve 14 is provided with a receiving cavity 1401, in which the first telescopic rod 121, the middle telescopic rod 122, and the last telescopic rod 123 are all housed, and the first telescopic rod 121 is connected to the sleeve 14. In this embodiment, there is one middle telescopic rod 122.

[0053] During use, an external air source supplies gas into the sleeve 14, and the air pressure inside the sleeve 14 gradually increases. When the gas pressure inside the sleeve 14 reaches a level sufficient to push the multi-section telescopic rod 12 to slide relative to each other, such as... Figure 5 As shown, the tail section telescopic rod 123 will first move relative to the middle telescopic rod 122. When the tail section telescopic rod 123 moves to the limit position relative to the middle telescopic rod 122, the middle telescopic rod 122 will extend to the limit length relative to the first section telescopic rod 121. Then the first section telescopic rod 121 will extend relative to the sleeve 14. In this way, the multiple telescopic rods 12 slide in sequence to push the massage head 2 to move, thereby achieving the purpose of the massage head 2 contacting the human body.

[0054] In some embodiments, to constrain the extension of the multi-section telescopic rods 12 to a certain distance before stopping and to prevent disengagement, each of the multi-section telescopic rods 12 is provided with a limiting structure to constrain the extension length. In this embodiment, please refer to... Figure 5 and Figure 7 As shown, the inner wall of the first telescopic rod 121 has a first protrusion 1211, the outer wall of the middle telescopic rod 122 has a first recess 1221, the inner wall of the middle telescopic rod 122 has a second protrusion 1222, and the outer wall of the tail telescopic rod 123 has a second recess 1231. When the second recess 1231 abuts against the second protrusion 1222, the tail telescopic rod 123 extends to its limit relative to the middle telescopic rod 122. As the air pressure inside the sleeve 14 increases, the middle telescopic rod 122 also extends relative to the first telescopic rod 121. When the first recess 1221 abuts against the first protrusion 1211, the middle telescopic rod 122 extends to its limit relative to the first telescopic rod 121.

[0055] In some embodiments, in order to ensure that the driver 30 transmits power to the plurality of telescopic rods 12 through the transmission assembly 20, reduce the risk of slipping between adjacent two telescopic rods 12, and ensure that the massage head 2 rotates around the central axis of the massage assembly 10, a rotation-stopping structure is arranged between adjacent two telescopic rods 12, the rotation-stopping structure comprises a clamping groove and a clamping protrusion matched with the clamping groove, one of the adjacent two telescopic rods is provided with the clamping groove, and the other is provided with the clamping protrusion. At the same time, in order to avoid slipping between the first telescopic rod 121 and the sleeve 14 during rotation, a rotation-stopping structure is also arranged between the first telescopic rod 121 and the sleeve 14.

[0056] The direction in which the plurality of telescopic rods 12 extends is defined as a first direction X, and the sleeve 14 comprises an open end 14a and a closed end 14b which are oppositely arranged along the first direction X, and the open end 14a is one end of the plurality of telescopic rods 12 relative to the sleeve 14.

[0057] In some embodiments, as shown in Figure 8 and Figure 9 The sleeve 14 comprises a barrel 141, the barrel 141 comprises a barrel wall 1410 and at least one protrusion 1412, the wall surface of the barrel wall 1410 in the first direction X towards the plurality of telescopic rods 12 is a first wall surface 14101, the protrusion 1412 is arranged on the first wall surface 14101, and the protrusion 1412 abuts against the tail telescopic rod 123, so as to form an air inlet gap 101 between the tail telescopic rod 123 and the first wall surface 14101. That is, the air inlet gap 101 is arranged between the tail telescopic rod 123 and the barrel 141 of the sleeve 14, which can reduce the risk of adsorption caused by the close fit between the tail telescopic rod 123 and the first wall surface 14101 of the barrel 141, and the difficulty of relative telescoping.

[0058] The structure of the barrel 141 can be arranged as needed. For example, as shown in Figure 8 and Figure 9 In some embodiments, the barrel 141 comprises a side wall portion 141a, a bottom wall portion 141b, and a boss portion 141c which is protruding relative to the bottom wall portion 141b, the side wall portion 141a, the bottom wall portion 141b and the boss portion 141c jointly form a receiving cavity 1401, and the surface of the boss portion 141c in the first direction X close to the massage head 2 is the first wall surface 14101. In other embodiments, the barrel 141 comprises a side wall portion 141a and a bottom wall portion 141b, and the side wall portion 141a and the bottom wall portion 141b jointly form a receiving cavity 1401, at this time the boss portion 141c can be omitted, and at this time the surface of the bottom wall portion 141b in the first direction X towards the massage head 2 is the first wall surface 14101.

[0059] The number of the first protrusions 1211 can be set as required, and can be one, two, or more than two. When the number of the first protrusions 1211 is two or more than two, the first protrusions 1211 can be arranged at equal intervals or at unequal intervals, or can be arranged symmetrically or asymmetrically. In the embodiment, the number of the first protrusions 1211 is four, and the four first protrusions 1211 are arranged at equal intervals on the first wall surface 14101.

[0060] In some embodiments, as shown in Figure 8 With Figure 9 As shown in the figure, the sleeve 14 further comprises a limiting ring 142, which is located in the receiving cavity 1401 and at the open end 14a of the sleeve 14. The limiting ring 142 is used to constrain the first telescopic rod 121 to extend out of the receiving cavity 1401 by a preset length relative to the sleeve 14, so as to avoid the first telescopic rod 121 from being pushed out of the sleeve 14 under the action of the air pressure in the sleeve 14, and facilitate the reciprocating extension and retraction of the multi-section telescopic rod 12 relative to the sleeve 14 to achieve the massage effect. In the embodiment, the limiting ring 142 and the barrel 141 of the sleeve 14 are connected by a pin shaft. The outer wall surface of the first telescopic rod 121 is provided with a recessed portion 1212, and the limiting ring 142 is provided with a limiting portion 1421 which protrudes relative to the inner wall surface of the side wall portion 141a.

The massage ball 22 is used to contact the human body to massage the human body when the multi-section telescopic rod 12 rotates with the driving of the driver 30 through the transmission assembly 20. In the embodiment, two massage balls 22 are arranged on the connecting plate 21. It can be understood that the number of the massage balls 22 is not limited to two, and can be one or more than two, which can be set as required.

[0062] It should be understood that, in order to avoid the leakage of the gas when the external gas source is connected to the sleeve 14, and to avoid affecting the efficiency of pushing the multi-section telescopic rod 12 to extend out, the mutual sealing of the multi-section telescopic rod 12 needs to be ensured, i.e., a sealing structure needs to be arranged between the two telescopic rods 12 which are arranged in each other, and between the sleeve 14 and the first telescopic rod 121, so as to push the multi-section telescopic rod 12 to extend out relative to the sleeve 14 when the air pressure in the sleeve 14 reaches a preset value.

The first sealing ring 31 is used to realize sealing between the sleeve 14 and the first section telescopic rod 121, the second sealing ring 32 is used to realize sealing between the middle section telescopic rod 122 and the first section telescopic rod 121, and the third sealing ring 33 is used to realize sealing between the middle section telescopic rod 122 and the tail section telescopic rod 123.

[0064] In some embodiments, as shown in Figure 4 With Figure 5 As shown in the figure, the massage device 100 further comprises an air slide ring 40. The sleeve 14 is provided with an air inlet 143 which is in communication with the multi-section telescopic rod 12. The center line of the air inlet 143 is in line with the center axis of the sleeve 14, that is, the air inlet 143 is arranged at the axial center position of the sleeve 14.

The specific mode can be set as required. When the air slide ring 40 and the air inlet 143 are connected by the threaded connection mode, the air inlet 143 is provided with an internal thread, and the air slide ring 40 is provided with an external thread. The external thread is screwed with the internal thread to realize the threaded connection between the air slide ring 40 and the air inlet 143.

[0066] In some embodiments, as shown in Figure 4 With Figure 5As shown, the massage device 100 further comprises a housing 50, the at least one massage assembly 10 is mounted on the housing 50, and the housing 50 is provided with a receiving cavity 501, the transmission assembly 20 and the driver 30 are all received in the receiving cavity 501.

The massage head 2 is configured to move away from the sleeve 14 under the driving of the plurality of telescopic rods 12 which extend in sequence when the inside of the sleeve 14 is inflated. Compared with a pure pneumatic air bag massage device, the massage device 100 with the above structure reduces the risk that the massage head 2 deviates when contacting the user, is beneficial to improving the stability of massage, is beneficial to improving the user experience, and the massage head 2 is driven by the pneumatic telescopic mechanism 1 to transmit rotating power, which reduces the risk of twisting of the massage head 2 and has higher massage force.

[0072] As shown in Figures 10-11 , the pneumatic massage system 600 provided by another embodiment of the present application comprises an air pump 200, at least one first control valve 300, a second control valve 400 and at least one massage device 100 of the above embodiment.

[0073] As shown in Figure 10 , the air outlet of the air pump 200 is connected with the first interface of the at least one first control valve 300, and the air inlet 143 of one massage device 100 is connected with the second interface of one first control valve 300. The air inlet 143 of the air pump 200 is connected with the first interface of the second control valve 400, the second interface of the second control valve 400 is respectively communicated with the third interface of the plurality of first control valves 300, and the third interface of the second control valve 400 is used for being communicated with the external environment.

[0074] Thus, when the massage device 100 is normally supplied with gas, the third interface of the second control valve 400 is in communication with the external environment, the air pump 200 can suck the air outside through the third interface and supply the gas to the first interface of the first control valve 300 through the air outlet of the air pump 200, and the gas is then rushed to the sleeve 14 of the gas massage device 100 through the second interface of the first control valve 300, so as to push the multi-section telescopic rod 12 to extend relative to the sleeve 14. When deflation is needed, the third interface of the second control valve 400 is closed at this time, the air pump 200 sucks the air from the third interface of the plurality of first control valves 300 through the second interface of the second control valve 400, and then indirectly sucks away the gas in the massage device 100 through the second interface, so as to accelerate the deflation speed of the massage device 100.

[0075] In some embodiments, the first control valve 300 is a three-position three-way valve or a two-position three-way valve, and the second control valve 400 is a three-position three-way valve or a two-position three-way valve.

[0076] In some embodiments, as shown in Figure 11 The pneumatic massage system 600 further comprises a negative pressure tank 500 connected between the second interface of the second control valve 400 and the third interfaces of the plurality of first control valves 300. Thus, the air pump 200 pre-emptively sucks the negative pressure tank 500 into negative pressure by sucking air, when the massage device 100 needs to deflate, the third interfaces of the plurality of first control valves 300 are opened, and due to the negative pressure formed in the gas path under the action of the negative pressure tank 500, the gas in the plurality of massage devices 100 will flow to the negative pressure tank 500 through the first control valve 300 at this time, which is beneficial to improve the deflation efficiency.

[0077] By using the pneumatic massage system 600, the multi-section telescopic rod 12 can be extended or retracted relative to the sleeve 14 to adjust the position of the massage head 2 by repeatedly inflating and deflating the massage device 100, thereby achieving the massage effect.

[0078] The above description is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation according to the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
