Description

Technical Field

[0001] This invention relates to the technical field of massage therapy, and particularly to a rotary telescopic massage machine.

Background Art

[0002] A massage machine is a device that performs massage therapy for the purpose of promoting blood circulation in body parts that are difficult to move (generally, after surgery such as hand injuries). Therefore, many automatic massage machines have been developed, such as a rotary massage machine that combines a motor and a flexible massage sleeve inside a cylindrical shell. However, since the cylindrical shell of such a massage machine cannot be disassembled, it is inconvenient to remove the flexible massage sleeve, and it is also inconvenient to reassemble it after disassembly and cleaning. Therefore, there is an urgent need for a massage machine that can solve the above technical problems.

[0019] This invention will be further described below in combination with the embodiments and accompanying drawings. [Examples]

[0020] As shown in Figures 1 to 26, the rotary telescopic massager described in this embodiment comprises a cylindrical outer shell 1, a massage member 4 installed inside the cylindrical outer shell 1, and a rotary telescopic device 2. The rotary telescopic device 2 drives the massage member 4 to move in a longitudinal reciprocating parallel motion along the cylindrical outer shell 1, while simultaneously driving the massage member 4 to rotate. This massager provides a massage suitable for an adult's finger or penis.

[0021] In this embodiment, as shown in Figures 1 to 3, 6, 13, and 15, the cylindrical outer shell 1 comprises a first cylindrical shell 11 and a second cylindrical shell 12. The port of the first cylindrical shell 11 is detachably joined to the port of the second cylindrical shell 12, and a rotary telescopic device 2 is mounted in the lumen of the first cylindrical shell 11. The rotary telescopic device 2 comprises a first mounting bracket 21, a first motor 23, a rotary actuator 24, a guide rod 247, a connecting rod 26, and a rotating disk 25. A guide passage 213 is formed in the first mounting bracket 21 and is installed along the axial direction of the cylindrical outer shell 1, and the rotary actuator 24 is movably installed inside the guide passage 213, at least a portion of which is movably mounted. The rotating disk 25 is mounted on the rotation axis of the first motor 23, the axis of the guide rod 247 is set parallel to the axis of the rotary actuator 24, and the rotary actuator 24 is slidably connected to the guide rod 247. The rotary actuator 24 comprises a movable member 241 and a second motor 243. The second motor 243 is fitted and fixed inside the mounting cavity 242 of the movable member 241, i.e., the movable member 241 has a sleeve structure. The port of the sleeve-structured movable member 241 is sealed via a cover plate, after which the second motor 243 is fixedly mounted, and a gear set 245 is drive-connected to the rotation axis of the second motor 243. The gear set 245 is generally a planetary gear set, and a rotary output shaft 246 is installed on the gear set 245. The rotary output shaft 246 extends from one end of the movable member 241 facing the massage member 4 and is detachably connected to the closed end of the cylindrical body 41. The end of the connecting rod 26 is rotatably connected to the outside of the movable member 241; that is, the shaft portion 244 is installed on the outside of the end of the movable member 241 that is close to the second motor 243, and is hinged to the inside of the hinge hole 261 at one end of the connecting rod. By hinged the eccentric shaft 251 to the inside of the hinge hole 261 at the other end of the connecting rod, both ends of the connecting rod 26 are rotatably connected to the outside of the rotary actuator 24 and the eccentric part of the rotating disk 25, respectively.When operating in this configuration, the first motor 23 is energized to drive the rotating disk 25 to rotate, causing the eccentric shaft 251 to move circumferentially around the rotation axis of the first motor 23, thereby pushing and pulling the movable member 241. As a result, the movable member 241 expands and contracts along its axis inside the guide passage 213. Simultaneously, the second motor 243 is energized to drive the massage member 4 to rotate, thereby enabling the massage member 4 to perform a rotational and retractable massage function on the fingers or penis of the human body.

[0022] The massage member 4 is installed in the lumen of the second cylindrical shell 12. The massage member 4 comprises a cylindrical body 41 and a flexible massage sleeve 42 installed inside the cylindrical body 41. The closed end of the cylindrical body 41 is detachably connected to the rotating part of the rotary actuator 24, and the opening of the flexible massage sleeve 42 is positioned in the same direction as the opening of the second cylindrical shell 12. The flexible massage sleeve 42 is made of flexible silicone material to ensure comfort when in contact with the skin of a human finger or penis. The distance from the bottom of the massage cavity 421 of the flexible massage sleeve 42 to the open end of the second cylindrical shell 12 is adapted to the length of an average adult finger or penis. Therefore, when performing rotational and retractable massage with this structure, when a finger or penis is inserted into the massage cavity 421 of the flexible massage sleeve 42, the flexible massage projection 422 located inside the massage cavity 421 comes into contact with the skin of the finger or penis, and massages the finger or penis during the rotational and retractable movement of the flexible massage sleeve 42, promoting blood circulation. The inner diameter of the massage cavity 421 is set to match the outer diameter and length of an adult's finger or penis.

[0023] Preferably, a sealing ring 7 is fitted and engaged with the portion of the movable member 241 located inside the guide passage 213. The outer circumferential wall of the sealing ring 7 is positioned to contact the inner wall of the guide passage 213, thereby sealing the space between the movable member 241 and the guide passage 213 and preventing moisture or other substances from entering the lumen of the first cylindrical shell 11.

[0024] In this embodiment, as shown in Figures 11, 12, 23, and 24, a connecting cylinder 210 is integrally formed with the first mounting bracket 21, and the first cylindrical shell 11 is fitted onto the first half 211 of the connecting cylinder 210. The second cylindrical shell 12 is sealed and fitted onto the second half 212 of the connecting cylinder 210 via a sealing ring 7, and a plurality of L-shaped locking grooves 121 and a plurality of locking blocks 220 arranged in an annular pattern are installed on the outer wall of the connecting cylinder 210 and the inner wall of the port of the second cylindrical shell 12 facing the connecting cylinder 210. The locking blocks 220 are locked into the horizontal grooves 1211 of the L-shaped locking grooves 121 via the vertical grooves 1212 of the L-shaped locking grooves 121, thereby realizing a detachable connection between the first cylindrical shell 11 and the connecting cylinder 210. This structure makes it easy to attach and detach.

[0025] In this embodiment, the rotary output shaft 246 is detachably connected to the closed end of the cylindrical body 41 in the following two implementation structures.

[0026] The first implementation structure is as follows. As shown in Figures 3, 4, 8 to 10, and 27, a first connecting sleeve 28 is fixed to the rotating output shaft 246, that is, a connecting shaft 27 is fixed to the rotating output shaft 246, and the end of the connecting shaft 27 has a polygonal structure. A polygonal insertion hole 281 is provided in the first connecting sleeve 28, and after the polygonal structure of the connecting shaft 27 is inserted into the polygonal insertion hole 281 of the first connecting sleeve 28, the end faces of the first connecting sleeve 28 and the connecting shaft 27 are fixedly connected via bolts. A second connecting sleeve 412 is provided at the closed end of the cylindrical body 41, and the first connecting sleeve 28 and the second connecting sleeve 412 are fitted together, and the first connecting sleeve 28 and the second connecting sleeve 412 are connected by a buckle. Specifically, multiple elastic pieces 283 are formed on the outer circumferential wall of the first connecting sleeve 28 by installing multiple neutrals 282, and multiple hooking blocks 284 arranged in an annular pattern are formed on the elastic pieces 283. Multiple hooking slots 4121 arranged in an annular pattern are formed on the inner circumferential wall of the second connecting sleeve 412, and when the second connecting sleeve 412 is fitted onto the first connecting sleeve, the hooking blocks 284 are locked into the inside of the hooking slots 4121, thereby achieving a locked connection.

[0027] The second implementation structure is as follows. As shown in Figures 13 to 24, a connecting shaft 27 is fixed to the rotating output shaft 246, and a first connecting member 8 is fixed to the connecting shaft 27. A support member 10 is installed between the first connecting member 8 and the port of the guide passage 213, the connecting shaft 27 passes through a through hole 105 in the support member 10, and the support member 10 is fixed in the radial direction. Two first conductors 82 are installed on the first side surface 85 of the first connecting member 8 facing the support member 10, and two second conductors 104 are installed on the third side surface 106 of the support member 10 facing the first connecting member 8, and each first conductor 82 is in conductive contact with each of the two second conductors 104. The two first conductors 82 are annular conductors installed around the connecting shaft, and the two second conductors 104 are conductive needles or conductive elastic pieces. Alternatively, the two first conductors 82 are conductive needles or conductive elastic pieces, and the two second conductors 104 are annular conductors arranged around a connecting shaft. A second connecting member 9 is installed at the closed end of the cylindrical body 41, and the first connecting member 8 and the second connecting member 9 are connected via a buckle, and two third conductors 83 are installed on the second side surface 86 of the first connecting member 8 facing the second connecting member 9. Two fourth conductors 92 are installed on the fourth side surface 93 of the second connecting member 9 facing the first connecting member 8, and each third conductor 83 is electrically in contact with each other by the two fourth conductors 92. The two third conductors 83 are annular conductors arranged around a connecting shaft, and the two fourth conductors 92 are conductive needles or conductive elastic pieces. Alternatively, the two third conductors 83 are conductive needles or conductive elastic pieces, and the two fourth conductors 92 are annular conductors positioned around the connecting shaft 27. Here, each first conductor 82 is electrically connected to the two third conductors 83, and the flexible massage sleeve 42 is fitted with a massage function component. The two fourth conductors 92 are electrically connected to the massage function component after passing through the closed end of the cylindrical body 41 via conductive connecting wires.The massage function component is a first vibrator or an electric heating sheet. The first vibrator uses a vibration motor, and the electric heating sheet uses a graphene heating sheet or a copper wire heating sheet. This structure ensures that the first vibrator or electric heating sheet is energized properly while the massage member 4 is rotating, and prevents the conductive connecting wires from becoming entangled. This ensures that while the massage member 4 is rotating, the two first conductors 82 are always in contact with the two second conductors 104, and the first connecting member 8 and the second connecting member 9 are fixed in place. Therefore, the third conductor 83 is also always in contact with the fourth conductor 92, thereby ensuring a stable power supply to the first vibrator or electric heating sheet.

[0028] More preferably, the first connecting member 8 comprises a first connecting sleeve 28 and a first annular plate 81. The first annular plate 81 is fixed inside the first connecting sleeve 28, and a first side surface 85 and a second side surface 86 are provided on the first annular plate 81. Two first conductors 82 are provided on the first side surface 85 of the first annular plate 81 facing the support member 10, and two third conductors 83 are provided on the second side surface 86 of the first connecting sleeve facing the massage member 4. The second connecting member 9 comprises a second connecting sleeve 412 and a second annular plate 91. The first connecting sleeve 28 and the second connecting sleeve 412 are fitted together, and the first connecting sleeve 28 and the second connecting sleeve 412 are connected by a buckle. Specifically, multiple elastic pieces 283 are formed on the outer circumferential wall of the first connecting sleeve 28 by installing multiple neutrals 282, and multiple hooking blocks 284 arranged in an annular shape are formed on the elastic pieces 283, and multiple hooking slots 4121 arranged in an annular shape are formed on the inner circumferential wall of the second connecting sleeve 412. When the second connecting sleeve 412 is fitted into the first connecting sleeve, the hooking blocks 284 are locked into the inside of the hooking slots 4121, thereby achieving a locked connection. A fourth side surface 93 is installed on the second annular plate 91, and the second annular plate 91 is fixed inside the second connecting sleeve 412, and the two fourth conductors 92 are installed on the fourth side surface 93 of the second annular plate 91 facing the first connecting member 8. The support member 10 comprises an annular support plate 102 and a third annular plate 101. A third side surface 106 is installed on the third annular plate 101, the third annular plate 101 is fixed to a fifth side surface 107 of the annular support plate 102 facing the second annular plate 91, and the two second conductors 104 are installed on the third side surface 106 of the third annular plate 101 facing the second annular plate 91.Here, the first connecting sleeve 28, the first annular plate 81, the second connecting sleeve 412, the second annular plate 91, the annular support plate 102, and the third annular plate 101 are installed coaxially, and the connecting shaft 27 passes through the annular support plate 102 and the third annular plate 101 in order before being fixedly connected to the first connecting sleeve 28. That is, the end of the connecting shaft 27 has a polygonal structure, and the first connecting sleeve has a polygonal insertion hole 281. The polygonal structure of the connecting shaft 27 is inserted into the polygonal insertion hole 281 of the first connecting sleeve 28, and then the first connecting sleeve 28 is fixedly connected to the end face of the connecting shaft with bolts. At least one guide rod 103 is installed on the annular support plate 102, and the guide rod 103 is inserted into the guide hole 214 of the mounting bracket, fixing the support member 10 in the radial direction. The power supply device is electrically connected to the two second conductors 104 via conductive connecting wires. The power supply device uses a battery 17.

[0029] To ensure a reliable conductive connection, each first conductor 82 is electrically connected to two third conductors 83 via a conductive connection pin 84.

[0030] Preferably, the first annular plate 81, the second annular plate 91, and the third annular plate 101 all use circuit boards, and the two annular conductors generally use two annular copper plates with different outer diameters that are mounted coaxially.

[0031] Therefore, when removing the first cylindrical shell 11 and the second cylindrical shell 12, the first cylindrical shell 11 and the second cylindrical shell 12 rotate in the axial direction, displacing the locking block 220 on the first cylindrical shell 11 into the vertical groove 1212 of the L-shaped locking groove 121. Then, as the first cylindrical shell 11 and the second cylindrical shell 12 move relative to each other in the axial direction, the locking block disengages from the vertical groove 1212 of the L-shaped locking groove 121, and the removal and separation of the first cylindrical shell 11 and the second cylindrical shell 12 is achieved. Once the first cylindrical shell 11 and the second cylindrical shell 12 are removed and separated, the massage member 4 is fully exposed, and the connection between the massage member 4 and the rotation output shaft 246 of the rotary actuator 24 can be released. When releasing, because the hook block 284 has an inclined surface in the connection and contact direction, the cylindrical body 41 simply moves outward in the axial direction, and the hook block 284 is guided by the inclined surface and disengages from the hook slot 4121, achieving connection and contact, and the massage member 4 and the first cylindrical shell 11 equipped with the rotational extension device 2 become independent of each other.

[0032] Furthermore, the connecting cylinder 210, the first cylindrical shell 11, and the second cylindrical shell 12 are all installed in a cylindrical shape, a position-restricting recess 285 is formed on the outer wall of the first connecting sleeve 28, and a position-restricting projection 4122 is formed on the inner wall of the second connecting sleeve 412. The position-restricting projection 4122 is fitted inside the position-restricting recess 285, so that the first connecting sleeve 28 and the second connecting sleeve 412 are radially restricted from each other, and both the position-restricting projection 4122 and the position-restricting recess 285 have an elongated structure in the axial direction.

[0033] In this embodiment, as shown in Figures 5 and 17, a guide sleeve 2411 is installed on the outer wall of the movable member 241. The guide rod 247 is fixed to the inner wall of the first mounting bracket 21 or the first cylindrical shell 11, and the guide sleeve 2411 is placed over the guide rod 247. The first mounting bracket 21 has a first fixing hole 216, and the first fixing sleeve 217 is fitted and fixed to one end of the guide rod 247. The first fixing sleeve 217 is inserted into the first fixing hole 216, and the first fixing hole 216 and the first fixing sleeve 217 are fixed by interference fit. Generally, the guide rod 247 is made of metal to better support the rotary actuator 24 and improve the stability of the structure. In addition, two guide rods 247 are installed and are installed symmetrically. The guide sleeve 2411 and the first fixing hole 216 are both provided in pairs and are installed symmetrically, which allows for a more stable, compact, and reliable structure when the rotary actuator extends and retracts.

[0034] Preferably, the rotary telescopic device 2 further comprises a second mounting bracket 22 fixedly connected to the inner wall of the first cylindrical shell 11. The first motor 23 is fixed to the second mounting bracket 22, which has a second fixing hole 218 formed therein. A second fixing sleeve 219 is fitted and fixed to the other end of the guide rod 247. The second fixing sleeve 219 is inserted into the second fixing hole 218, and the second fixing hole 218 and the second fixing sleeve 219l are fixed by interference fit. By installing it in this structure, the fixing of the guide rod 247 is more stable, and two second fixing holes 218 are provided and are installed symmetrically.

[0035] In this embodiment, as shown in Figures 1 to 3, 10, 13, and 15, a flexible sleeve 5 is attached to the opening of the second cylindrical shell 12, and a through passage 51 is formed in the flexible sleeve 5. The through passage 51 is installed coaxially with the massage cavity 421 of the flexible massage sleeve 42, and a plurality of flexible massage protrusions 422 are formed on the inner wall of the massage cavity 421 of the flexible massage sleeve 42. Since the flexible sleeve 5 also uses a flexible silicone material, it provides more comfortable support to the base of the finger or penis, and the flexible massage protrusions 422 make close contact with the skin of the finger or penis. Here, the opening of the second cylindrical shell 12 and the outer wall of the flexible sleeve 5 are fitted together by interlocking grooves and protrusions. Specifically, a protruding ring 122 and an annular slot 54 are formed on the inner wall of the opening of the second cylindrical shell 12 and the outer wall of the flexible sleeve 5, respectively, and the protruding ring 122 is fitted into the annular slot 54 to fix the flexible sleeve 5 in place.

[0036] In this embodiment, as shown in Figures 7, 25, and 26, a vacuum pump 15 and a solenoid valve 16 are installed inside the first cylindrical shell 11. The lumen of the connecting cylinder 210 and the lumen of the second cylindrical shell 12 are joined to form a negative pressure massage cavity 14. A pressure outlet 222 and an extraction port 215 are installed in the partition plate 221 of the first mounting bracket 21. The intake port 151 of the second vacuum pump 15 is abutted against the extraction port 215 via a duct 18. The gas intake port 191 of the solenoid valve 16 is abutted against the pressure outlet 222 via a duct 18. The gas outlet 192 of the solenoid valve 16 and the exhaust port 152 of the second vacuum pump 15 are abutted against two gas discharge holes 20 in the first cylindrical shell 11 via a duct 18. After a finger or penis penetrates the flexible sleeve 5 and is inserted into the negative pressure massage cavity 14, the inner wall of the flexible sleeve 5 adheres tightly to the skin at the base of the finger or penis, sealing the negative pressure massage cavity. At this time, the solenoid valve 16 can be shut off. Subsequently, the vacuum pump 15 is activated to draw in air, continuously expelling air from inside the negative pressure massage cavity 14. This creates a negative pressure state in the negative pressure massage cavity 14, and the air pressure applies pressure to the flexible massage sleeve 42 through the air flow port 411 on the cylindrical body 41, causing the flexible massage projection 422 on the inner wall of the flexible massage sleeve 42 to compress the finger or penis, achieving negative pressure massage. After the air has been extracted for a predetermined time, the operation of the vacuum pump 15 stops, the solenoid valve 16 becomes conductive, and air flows into the negative pressure massage cavity 14 through the flow passage in the solenoid valve. This releases the flexible massage sleeve 42, relieving the pressure on the finger or penis. Finally, this negative pressure massage method allows for multiple negative pressure massages on the finger or penis. The internal opening of the flexible sleeve 5 is set to fit an adult's finger or penis.

[0037] Preferably, the first port of the three-way joint 19 is connected to the port of the flow passage of the solenoid valve 16, the second port of the three-way joint 19 functions as a gas inlet 191, and the third port of the three-way joint 19 functions as a gas outlet 192.

[0038] More preferably, the first cylindrical shell 11, the second cylindrical shell 12, the first mounting bracket 21, the second mounting bracket 22, the first connecting sleeve, the second connecting sleeve 412, the movable member 241, and the cylindrical body 41 are all made of plastic, thereby reducing the overall weight of the massage machine.

[0039] In this embodiment, as shown in Figures 1, 3, 6, 13, and 15, a control circuit board 3 is installed inside the lumen of the first cylindrical shell 11. The control circuit board 3 is equipped with an MCU control chip, a switch button 31, a function control button 32, and a power supply device. 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 power to the first motor 23, the second motor 243, the vacuum pump 15, and the solenoid valve 16. Power supply is controlled by the switch button 31, the function control button 32, and the MCU control chip. The power supply device uses a battery 17, and the charging interface 6 is electrically connected to the battery 17. The charging interface 6 penetrates the first cylindrical shell 11 and the outer cylindrical shell 13. The charging interface 6 generally uses a TYPE-C interface or a USB interface.

[0040] In this embodiment, as shown in Figure 26, an outer cylindrical shell 13 made of plastic material is fitted and fixed to the outer wall of the first cylindrical shell 11 to protect the first cylindrical shell 11. The switch button 31 and the function control button 32 both extend from the first cylindrical shell 11 and the outer cylindrical shell 13, and the two holes in the outer cylindrical shell 13 are installed to communicate with each gas exhaust hole 20.

[0041] As shown in Figure 3, in another embodiment, a second vibrator 53 is fitted and tightly installed inside the insertion groove 52 of the flexible sleeve 5. The second vibrator 53 is close to the inner wall of the through passage 51, and the power supply is electrically connected to the second vibrator 53 after passing through the first mounting bracket via a conductive connecting wire. The power supply uses a battery 17. By installing it in this structure, a variety of massage functions are realized and the effect of the massage experience is improved. The second vibrator 53 uses a vibration motor, and the embedded slot 52 is installed communicating with the lumen of the second cylindrical shell 12 via a separately provided wiring passage in the flexible sleeve 5. This allows the second vibrator 53 to be easily installed. This embodiment is mainly applied to a rotary telescopic massage machine having the first embodiment structure described above, but it can also be applied to a rotary telescopic massage machine having the second embodiment structure described above, depending on the actual demand.
