[0040] Reference Figures 1 to 3The utility model provides a kind of flexible massage equipment, including mounting seat 3, telescopic component 1 and at least one through channel 2, mounting seat 3 is suitable for installing pressure charging component;Telescopic component 1 is suitable for fixed installation in mounting seat 3, telescopic component 1 includes telescopic structure 11 and outer sleeve 12, telescopic structure 11 is arranged in the inside of outer sleeve 12 and first accommodating cavity 120 is equipped between telescopic structure 11 and outer sleeve 12;Telescopic structure 11 has second accommodating cavity 110, and second accommodating cavity 110 is connected with pressure charging component;Through channel 2 is suitable for through connection first accommodating cavity 120 and outside, so that telescopic structure 11 expands, and outer sleeve 12 is more fitted telescopic structure 11.

[0041] In the embodiment, the through channel 2 connects the first accommodating cavity 120 between the telescopic structure 11 and the outer sleeve 12 with the outside, and the first accommodating cavity 120 exchanges air pressure with the outside through the through channel 2 when the air pressure changes, balances the air pressure between the first accommodating cavity 120 and the outside, and avoids the uneven air pressure in the first accommodating cavity 120 from causing the outer sleeve 12 to be unevenly pressed by atmospheric pressure.

[0042] Specifically, the through channel 2 is mainly used to maintain the air pressure balance between the first accommodating cavity 120 and the outside. The telescopic structure 11 has a first opening at one end, and the outer sleeve 12 has a third opening at one end. The first opening of the telescopic structure 11 and the third opening of the outer sleeve 12 are both suitable for being sleeved on the mounting seat 3. The number of through channels 2 is at least one, and the present application does not make further limitations. The telescopic structure 11 is located inside the outer sleeve 12, and the first accommodating cavity 120 is arranged between the outer side wall of the telescopic structure 11 and the inner side wall of the outer sleeve 12. The telescopic structure 11 has a second accommodating cavity 110 inside, and the second accommodating cavity 110 is connected with the pressure charging component on the mounting seat 3. The pressure charging component is suitable for injecting fluid into the second accommodating cavity 110 and driving the telescopic structure 11 to deform. The through channel 2 penetrates the mounting seat 3 and connects the first accommodating cavity 120 with the outside. The penetration direction of the through channel 2 can be along the axial direction of the telescopic component 1, or along the radial direction of the telescopic component 1, and the present application does not make further limitations. The through channel 2 penetrates the mounting seat 3 and connects the first accommodating cavity 120 with the outside, avoiding the opening in the outer sleeve 12, and ensuring the airtightness and waterproof performance of the outer sleeve 12. The shape of the through channel 2 is not limited in the present application, which can be linear, curved, arc-shaped, or irregularly shaped.

[0043] Reference Figures 4 to 6The mounting seat 3 comprises a first seat body 31, and first abutting walls 311, second abutting walls 312 and third abutting walls 313 are sequentially and spacedly arranged on the outer side wall of the first seat body 31. The first abutting walls 311 are located at the top end of the first seat body 31, the third abutting walls 313 are located at the bottom of the first seat body 31, the second abutting walls 312 are located between the first abutting walls 311 and the second abutting walls 312, the first installation grooves 314 are arranged between the first abutting walls 311 and the second abutting walls 312, the second installation grooves 315 are arranged between the second abutting walls 312 and the third abutting walls 313, the first installation blocks 111 are arranged on the inner side wall of one end of the telescopic structure 11, the first installation blocks 111 are sleeved in the first installation grooves 314, the third installation blocks 121 are arranged on the inner side wall of one end of the outer sleeve 12, and the third installation blocks 121 are sleeved in the second installation grooves 315. The first holes 3121 are arranged on the second abutting walls 312, the second holes 3131 are arranged on the third abutting walls 313, the through channel 2 comprises a through pipe 21, and the through pipe 21 penetrates the first holes 3121 of the second abutting walls 312 and the second holes 3131 of the third abutting walls 313. The end of the through pipe 21 is located between the outer side wall of the telescopic structure 11 and the inner side wall of the outer sleeve 12. When the telescopic structure 11 is deformed, the air in the first containing cavity 120 can be extruded out through the through channel 2, so that the outer sleeve 12 is more fitted to the telescopic structure 11, and uneven air pressure in the first containing cavity 120 can be avoided. When the telescopic structure is axially deformed and radially shrunk, the air outside can reach the first containing cavity 120 through the through channel 2, the through channel 2 can supplement the fluid in the first containing cavity 120, so that the air pressure in the first containing cavity 120 is balanced with the fluid pressure outside, and the air pressure in the first containing cavity 120 and the air pressure outside are balanced.

[0044] It is worth noting that the through pipe 21 can also be replaced by a hole, which is within the protection scope of the application. The radial length of the second abutting walls 312 is greater than that of the third abutting walls 313. The second seat body 32 is fixedly installed below the first seat body 31, and the outer side wall of the second seat body 32 is adapted to be sleeved on the outer side of the outer sleeve 12. The third holes 321 are arranged on the second seat body 32, and the through pipe 21 penetrates the second holes 3131 and then penetrates the third holes 321 of the second seat body 32. The first holes 3121, the second holes 3131 and the third holes 321 are matched with each other in position. The inner side wall of the second seat body 32 abuts against the outer side wall of one end of the outer sleeve 12, and the outer sleeve 12 is pressed and combined on the third installation blocks 121 of the outer sleeve 12, which are abutted and installed in the second installation grooves 315, so that the outer sleeve 12 is prevented from falling off.

[0045] In the deformed embodiment, referring to Figure 7 and Figure 8 The through channel 2 comprises a plurality of first through holes 22, and the first through holes 22 penetrate the outer sleeve 12 along the radial direction of the telescopic assembly 1 and connect the first containing cavity 120 and the outside.

[0046] In this embodiment, the first through hole 22 penetrates the outer sleeve 12 to communicate the first containing cavity 120 and the outside. Specifically, the first through hole 22 is arranged at the end of the outer sleeve 12 away from the mounting base 3. The deformation of the first through hole 22 is the smallest, and the durability of the outer sleeve 12 is better. A waterproof and breathable film can also be arranged in the first through hole 22, so that the first through hole 22 not only communicates the outside and the first containing cavity 120, but also isolates the outside moisture, thereby increasing the safety performance of the outer sleeve 12. The first through hole 22 arranged at the end of the outer sleeve 12 away from the mounting base 3 can also reduce the stretching degree of the waterproof and breathable film. The installation method and position of the waterproof and breathable film are various, and the present application does not make further limitation.

[0047] It is worth noting that the first through hole 22 can also be arranged at the end of the outer sleeve 12 close to the mounting base 3. In this embodiment, the first through hole 22 is located at the bottom of the outer sleeve 12, which is not easy to enter impurities, thereby ensuring that the first containing cavity 120 and the outside air flow are communicated while reducing the probability of impurities entering the first through hole 22. The first through hole 22 can also be arranged at the end of the outer sleeve 12 away from the mounting base 3 and the end of the outer sleeve 12 close to the mounting base 3. Moreover, the through channel 2 includes but is not limited to the through pipe 21 and the first through hole 22, and it can also pass through other through structures, as long as the first containing cavity 120 between the outer sleeve 12 and the telescopic structure 11 is communicated with the outside, that is, the through channel 2 can be a through hole, a through pipe, or a combination of a through hole and a through pipe, and the present application does not make further limitation here.

[0048] Further, the through channel 2 is also provided with an electromagnetic valve port arranged in the first through hole 22.

[0049] In this embodiment, the air pressure in the first containing cavity 120 is actively controlled through the electromagnetic valve port, so as to maintain the balance of the fluid pressure difference between the first containing cavity 120 and the outside.

[0050] Specifically, the electromagnetic valve port is arranged at the first through hole 22, so that the air pressure sensor detects the pressure in the first containing cavity 120. When the pressure in the first containing cavity 120 is high, the electromagnetic valve port discharges; when the pressure in the first containing cavity 120 is low, the electromagnetic valve port inflates, thereby better controlling the air pressure in the first containing cavity 120. The electromagnetic valve port can use a fluid pressure difference valve or an active relief device. The electromagnetic valve port is used to actively supplement the fluid in the first containing cavity 120, so that the air pressure in the first containing cavity 120 returns to balance with the fluid pressure difference of the outside.

[0051] It is worth noting that the through channel 2 is also provided with an air pressure sensor. Even the through channel 2 is also provided with a relief valve, that is, the relief valve adopts a mechanical structure principle to realize the outside interaction of the first containing cavity 120.

[0052] Further, the telescopic assembly 1 further comprises a limiting sleeve 13, which is arranged inside the outer sleeve 12 and sleeved outside the telescopic structure 11. The limiting sleeve 13 and the telescopic structure 11 are provided with a third accommodating cavity 130, and the limiting sleeve 13 and the outer sleeve 12 are provided with a first accommodating cavity 120. The limiting sleeve 13 is a porous knitted material, and the limiting sleeve 13 has pores and makes the third accommodating cavity 130 and the first accommodating cavity 120 communicate with each other.

[0053] In the embodiment, the limiting sleeve 13 is sleeved outside the telescopic structure 11 and located opposite to the inside of the outer sleeve 12. The pores on the limiting sleeve 13 guide the third accommodating cavity 130 between the limiting sleeve 13 and the telescopic structure 11 and the first accommodating cavity 120 between the limiting sleeve 13 and the inner wall of the outer sleeve 12 to communicate with each other. When the telescopic structure 11 expands and contracts, the limiting sleeve 13 is closely connected with the telescopic structure 11, the limiting effect of the limiting sleeve 13 on the telescopic structure 11 is better, and the limiting sleeve 13 can effectively prevent the air between the limiting sleeve 13 and the telescopic structure 11 from affecting the sensitivity and safety of the telescopic structure 11, and improve the smoothness of the outer sleeve 12.

[0054] Specifically, the telescopic structure 11 is provided with a first opening at one end, the limiting sleeve 13 is provided with a second opening at one end, and the outer sleeve 12 is provided with a third opening at one end. The first opening of the telescopic structure 11, the second opening of the limiting sleeve 13, and the third opening of the outer sleeve 12 are all adapted to be sleeved on the mounting seat 3. The outer sleeve 12, the limiting sleeve 13, and the telescopic structure 11 are sequentially sleeved, so that the telescopic structure 11 is located inside the limiting sleeve 13, and the limiting sleeve 13 is located inside the outer sleeve 12. The limiting sleeve 13 communicates the third accommodating cavity 130 between the limiting sleeve 13 and the telescopic structure 11 and the first accommodating cavity 120 between the limiting sleeve 13 and the inner side wall of the outer sleeve 12. When the telescopic structure 11 and the limiting sleeve 13 are installed, the limiting sleeve 13 will extrude the telescopic structure 11 and conductively connect the third accommodating cavity 130 with the outside, so that the air between the telescopic structure 11 and the limiting sleeve 13 is discharged through the limiting sleeve 13. The limiting sleeve 13 can be tightly attached to the telescopic structure 11, that is, the shape of the limiting sleeve 13 is consistent with the shape of the telescopic structure 11. Therefore, it is not necessary to manually extrude the limiting sleeve 13 and manually discharge the air in the third accommodating cavity 130, thereby reducing the installation steps. At this time, the first accommodating cavity 120 and the third accommodating cavity 130 are both in communication with the outside. When the telescopic structure 11 expands and contracts, the telescopic structure 11 extrudes the air in the third accommodating cavity 130 into the first accommodating cavity 120. The inner side wall of the limiting sleeve 13 and the outer side wall of the telescopic structure 11 always abut, so that the limiting sleeve 13 can timely limit the change of the telescopic structure 11 and has better response speed. In this way, the air between the telescopic structure 11 and the limiting sleeve 13 is prevented from being gathered at a certain position in the third accommodating cavity 130 after the telescopic structure 11 completely expands and contracts, so as to avoid that the outer surface of the limiting sleeve 13 is concave-convex, thereby affecting the smoothness of the outer surface of the outer sleeve 12, causing the hardness of each position of the outer sleeve 12 to be different, and even possibly causing an abnormal bulge of the outer sleeve 12. Therefore, the telescopic structure 11 is sleeved on the limiting sleeve 13 to discharge the air between the limiting sleeve 13 and the telescopic structure 11, so that the limiting sleeve 13 is more closely attached to the telescopic structure 11 during installation and operation, thereby improving the limiting sensitivity of the limiting sleeve 13 to the telescopic structure 11, increasing the smoothness of the surface of the limiting sleeve 13, and making the limiting sleeve 13 more closely attached to the surface of the telescopic structure 11. The limiting sleeve 13 is a knitted fabric, and the knitted fabric is provided with air holes. The air holes of the knitted fabric are formed during the manufacturing process of the knitted fabric, so it is not necessary to newly open air holes on the knitted fabric. This is because the loops of the knitted fabric are intertwined with each other, so that a large number of isolated air bags are formed in the knitted fabric, thereby having good warmth retention and air permeability. The knitted fabric includes warp-knitted fabric and weft-knitted fabric. In this application, the weft-knitted fabric is adopted and knitted into a loop. The narrow side of the loop is wide, so that the overall movement of the telescopic structure 11 will be biased to the vertical direction and be contracted. The knitted fabric is also a double-reversed fabric. The double-reversed fabric has great extensibility and elasticity when stretched in the longitudinal direction. This is because, in a free state, the loop column of the loop is recessed, so that the longitudinal direction is shortened. When the knitted fabric is stretched in the longitudinal direction, the inclined loop is straightened, the loop column is exposed, and then the transfer of the loop occurs.At the same time, the pressure between the coil contact points increases during stretching, hiding greater elastic potential, so the recovery characteristics are better after the external force is removed. The material of the knitted fabric can be aramid fiber, carbon fiber, polyethylene fiber, glass fiber, polyester fiber, cotton fiber, nylon fiber, polyester fiber, etc. It should be noted that the knitting method of the knitted fabric is not limited further in the application, which can be integrated knitting or combined knitting.

[0055] In the transformed embodiment, the limiting sleeve 13 can also be a high-elastic polymer, and a plurality of second through holes are provided through the high-elastic polymer, the second through holes being connected through the third accommodating cavity 130 and the first accommodating cavity 120. The high-elastic polymer includes but is not limited to rubber, thermoplastic elastomer, etc. The second through holes are exposed or cut out during molding.

[0056] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered within the protection scope of the present application.
