[0029] Accordingly, when the first cylinder housing 11 and the second cylinder housing 12 are disassembled, they are axially rotated relative to each other. This causes a detent block 220 on the first cylinder housing 11 to be moved into a longitudinal groove 1212 of an L-shaped detent groove 121. The first cylinder housing 11 and the second cylinder housing 12 then perform an opposing axial movement, disengaging the detent block from the longitudinal groove 1212 of the L-shaped detent groove 121. This disassembly and separation of the first cylinder housing 11 and the second cylinder housing 12 results in the complete removal and separation of the massage element 4. Once the first cylinder housing 11 and the second cylinder housing 12 are disassembled and separated, the massage element 4 is fully exposed, allowing the connection between the massage element 4 and a rotary output shaft 246 of a rotary drive 24 to be disconnected.Since the locking lug 284 has an inclined surface when released in one direction of electrical contact, a cylinder body 41 only needs to be moved axially outwards to ensure that the locking lug 284 is guided over the inclined surface out of a locking groove 4121 to release the electrical contact, causing the massage part 4 and the first cylinder housing 11 with a rotation and telescopic device 2 to each be in an independent state.

[0030] Furthermore, a connecting cylinder 210, the first cylinder housing 11, and the second cylinder housing 12 are each cylindrical. A limiting recess 285 is formed on an outer wall of the first connecting sleeve 28, and a limiting lug 4122 is formed on an inner wall of the second connecting sleeve 412, wherein the limiting lug 4122 is appropriately arranged in the limiting recess 285, such that the first connecting sleeve 28 and the second connecting sleeve 412 are mutually radially limited, and wherein both the limiting lug 4122 and the limiting recess 285 have an axially elongated structure.

[0031] In the present embodiment, as in Fig. 5 and Fig. Figure 17 shows a guide sleeve 2411 arranged on an outer wall of a movable part 241, wherein a guide rod 247 is attached to a first mounting bracket 21 or to an inner wall of the first cylinder housing 11, the guide sleeve 2411 being fitted onto the guide rod 247. A first mounting bore 216 is formed in the first mounting bracket 21, wherein a first mounting sleeve 217 is fixed to one end of the guide rod 247 via a plug connection, the first mounting sleeve 217 being inserted into the first mounting bore 216, and wherein the first mounting bore 216 and the first mounting sleeve 217 are secured by an interference fit. The guide rod 247 is generally made of a metal material, which provides better support for the rotary drive 24 and increases the stability of the structure.In addition, a number of the guide rods 247 are set to two and these are arranged symmetrically, wherein a number of the guide sleeves 2411 and a number of the first fastening holes 216 are each set to two and these are also arranged symmetrically, so that the rotary drive is more stable when performing a telescopic movement and the structure is more compact and reliable.

[0032] Preferably, the rotary and telescopic device 2 further comprises a second mounting bracket 22, wherein the second mounting bracket 22 is rigidly connected to the inner wall of the first cylinder housing 11, and wherein a first motor 23 is attached to the second mounting bracket 22. A second mounting bore 218 is formed on the second mounting bracket 22, wherein a second mounting sleeve 219 is fixed to the other end of the guide rod 247 via a plug connection, wherein the second mounting sleeve 219 is inserted into the second mounting bore 218, and wherein the second mounting bore 218 and the second mounting sleeve 219 are secured by an interference fit. This structural arrangement ensures a more stable fixation of the guide rod 247, and the number of second mounting bores 218 is set to two, and these are arranged symmetrically.

[0033] In the present embodiment, as in the Fig. 1 to Fig. 3, Fig. 10, Fig. 13 and Fig. Figure 15 shows a flexible sleeve 5 mounted on a mouth section of the second cylinder housing 12, wherein a through-channel 51 is formed on the flexible sleeve 5, the through-channel 51 being arranged coaxially to a massage chamber 421 of a flexible massage sleeve 42. A plurality of flexible massage projections 422 are formed on an inner wall of the massage chamber 421 of the flexible massage sleeve 42. The flexible sleeve 5 also uses a flexible silicone material, so that supporting a finger or the base of the penis is relatively comfortable. The flexible massage projections 422 ensure closer contact with the skin of the finger or penis.In this case, the mouth section of the second cylinder housing 12 and an outer wall of the flexible sleeve 5 are arranged in a form-fitting manner, that is, a convex ring 122 and an annular groove 54 are formed on an inner wall of the mouth section of the second cylinder housing 12 and on an outer circumferential wall of the flexible sleeve 5, and wherein the convex ring 122 is embedded in the annular groove 54 in order to firmly mount the flexible sleeve 5.

[0034] In the present embodiment, as in Fig. 7, Fig. 25 and Fig. As shown in Figure 26, a suction pump 15 and a solenoid valve 16 are arranged within the first cylinder housing 11. An inner cavity of the connecting cylinder 210 and an inner cavity of the second cylinder housing 12 are joined to form a vacuum massage chamber 14. An air pressure relief opening 222 and a suction opening 215 are arranged on a partition 221 of the first mounting bracket 21. An intake opening 151 of the suction pump 15 is connected to the suction opening 215 via a line 18. An air inlet opening 191 of the solenoid valve 16 is connected to the air pressure relief opening 222 via the line 18. An air outlet opening 192 of the solenoid valve 16 and an outlet opening 152 of the suction pump 15 are each coupled via the line 18 to two air outlet holes 20 on the first cylinder housing 11.Once the finger or penis has passed through the flexible sleeve 5 and is positioned inside the vacuum massage chamber 14, the inner wall of the flexible sleeve 5 presses against the skin of the base of the penis or finger, sealing the vacuum massage chamber. At this point, the solenoid valve 16 may be in the off state, after which the suction pump 15 is activated to perform a suction action, continuously drawing air out of the vacuum massage chamber 14. This creates a vacuum within the chamber, and the resulting air pressure, via an air circulation port 411 on the cylinder body 41, exerts pressure on the flexible massage sleeve 42. This pressure causes the flexible massage protrusions 422 on the inner wall of the flexible massage sleeve 42 to compress the finger or penis, thus producing a vacuum massage.After the air has been extracted for a certain period of time, the suction pump 15 stops operating, and the solenoid valve 16 is in a conductive state, allowing air to enter the vacuum massage chamber 14 via a circulation channel within the solenoid valve. This releases the flexible massage sleeve 42 and releases the pressure on the finger or penis. The finger or penis can then be subjected to multiple vacuum massages using this method. An internal bore in the flexible sleeve 5 is designed to fit an adult finger or penis.

[0035] Preferably, a first connection of a T-piece 19 is connected to a connection of the circulation channel of the solenoid valve 16, wherein a second connection of the T-piece 19 serves as an air inlet opening 191 and a third connection of the T-piece 19 serves as an air outlet opening 192.

[0036] Furthermore, preferably the first cylinder housing 11, the second cylinder housing 12, the first mounting bracket 21, the second mounting bracket 22, the first connecting sleeve, the second connecting sleeve 412, the movable part 241 and the cylinder body 41 are each made of a plastic material, thereby reducing the weight of the entire massage device. In the present embodiment, as in Fig. 1, Fig. 3, Fig. 6, Fig. 13 and Fig. As shown in Figure 15, a control circuit board 3 is arranged in the inner cavity of the first cylinder housing 11. An MCU control chip, a switch button 31, a function control button 32, and a power supply device are arranged on the control circuit board 3. The switch button 31, the function control button 32, and the power supply device are each connected to and controlled by the MCU control chip. The power supply device supplies current to the first motor 23, the second motor 243, the suction pump 15, and the solenoid valve 16. The power supply device is controlled by the switch button 31, the function control button 32, and the MCU control chip. The power supply device uses the battery 17, and a charging interface 6 is electrically connected to the battery 17. The charging interface 6 protrudes from the first cylinder housing 11 and an outer cylinder housing 13.The charging interface 6 generally uses a TYPE-C interface or a USB interface.

[0037] In the present embodiment, as in Fig. Figure 26 shows an outer cylinder housing 13 made of plastic material fixed to an outer wall of the first cylinder housing 11 via a plug connection to protect the first cylinder housing 11, and wherein both the switch button 31 and the function control button 32 protrude from the first cylinder housing 11 and the outer cylinder housing 13. Two holes on the outer cylinder housing 13 are each arranged in conjunction with the respective air outlet holes 20.

[0038] In another embodiment, as in Fig.Figure 3 shows a second vibrator 53 embedded within an embedding groove 52 of the flexible sleeve 5 and arranged in an interference fit, with the second vibrator 53 being located near an inner wall of the through-channel 51. The power supply device is conductively connected to the second vibrator 53 via a conductive connecting line that passes through the first mounting bracket, the power supply device using the battery 17. This structural arrangement allows for diversified massage functions and enhances the massage experience. The second vibrator 53 uses a vibration motor. The embedding groove 52 is arranged via a cable guide channel in conjunction with the inner cavity of the second cylinder housing 12, thus facilitating the assembly of the second vibrator 53.This embodiment is mainly applicable to the rotating and telescopic massage device with the first design structure described above, but can also be applied to the rotating and telescopic massage device with the second design structure described above, depending on actual requirements.
