Description

Technical Field

[0001] This invention relates to the field of telescopic machinery technology, and in particular to a rotary telescopic mechanism and a multifunctional massager. Background Technology

[0002] Telescopic devices are common in the mechanical field, and they have different telescopic forms and different application scenarios. For example, rotary massagers use rotary telescopic mechanisms, but most of the cylinders in existing massagers are single-cylinder and move in one direction, with limited massage functions and a relatively ordinary massage experience. Although other fields have rotary telescopic mechanisms, their structures are mostly complex, making it difficult to achieve rapid reciprocating telescopic movement, and their application scenarios are relatively limited.

[0003] The invention disclosed in CN117100567B is a multifunctional massager. It involves placing the area to be massaged into the inner cavity of a flexible massage cylinder. The elasticity of the cylinder causes flexible protrusions on its inner wall to contact the outer wall of the area to be massaged. A drive device then drives the telescopic component and the flexible massage cylinder to extend and retract, providing a frictional massage to the area. Alternatively, an air pump and an electronically controlled valve can be activated to extract air from the flexible massage cylinder, allowing it to tightly bind the area for a period before releasing. Releasing is achieved by closing a solenoid valve to allow outside air into the cylinder, while binding is achieved by an electronically controlled valve. While this method allows for diverse massage techniques, it cannot combine rotation and extension, impacting the user experience and failing to meet the requirements of different scenarios. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a rotary telescopic mechanism and a multifunctional massager that combines rotary and telescopic motion to meet the needs of different scenarios.

[0005] To achieve the above objectives, the present invention provides a rotary telescopic mechanism, comprising a rotary cylinder, a telescopic cylinder, and a mounting cylinder. The rotary cylinder and the telescopic cylinder are coaxially spaced within the mounting cylinder. A first gear ring is fixedly connected to the rotary cylinder, and a second gear ring is slidably connected to the telescopic cylinder. A driving mechanism is provided on the outer side of the mounting cylinder, and the gear of the driving mechanism meshes with the first gear ring and the second gear ring. A limiting groove is formed axially on the outer wall of the telescopic cylinder, and a limiting protrusion is provided on the inner wall of the second gear ring that slides with the limiting groove. A guide groove is provided circumferentially on the outer wall of the telescopic cylinder, and the guide groove is obliquely arranged axially. A guide member is passed through the side wall of the mounting cylinder, and the inner end of the guide member extends into the guide groove.

[0006] In this invention, the gears of the drive mechanism can drive the first and second gear rings meshing with them to rotate. Since the first gear ring is fixedly connected to the rotating cylinder, the rotating cylinder can rotate within the mounting cylinder. Because the second gear ring is slidably connected to the limiting groove of the telescopic rotating cylinder via a limiting protrusion, when the second gear ring rotates, the guide member and the guide groove slide relative to each other. Since the guide groove is axially offset and the position of the guide member is relatively fixed, the guide member can move the guide groove axially when the telescopic rotating cylinder rotates, meaning the telescopic rotating cylinder can also perform axial telescopic movement. This rotary telescopic mechanism of the present invention can be applied to the field of massagers, providing a continuous rotary massage effect through the rotating cylinder and a reciprocating telescopic and synchronous rotation massage effect through the telescopic rotating cylinder, allowing the user to experience various massage effects and expanding the application scenarios of the rotary telescopic mechanism.

[0007] Optionally, the drive mechanism includes a gearbox housing, a motor, and a transmission gear set. The gearbox housing is disposed on the outside of the mounting cylinder. The motor is fixedly disposed inside the gearbox housing and powered by a battery. The motor shaft is drivenly connected to the transmission gear set. The first transmission wheel of the transmission gear set meshes with the first gear ring, and the second transmission wheel of the transmission gear set meshes with the second gear ring.

[0008] In this invention, the rotation of the motor is transmitted to the first and second gear rings through a transmission gear set, eliminating the need for an additional power source and reducing production costs.

[0009] Optionally, the transmission gear set includes a worm gear, a worm shaft, and a gear axle. The worm shaft is connected to the rotating shaft of the motor, and the gear axle is rotatably installed inside the gearbox. The worm gear is sleeved on the gear axle and meshes with the worm shaft. A first bevel gear is sleeved on the gear axle. A second bevel gear and a third bevel gear are coaxially arranged and mesh on the first bevel gear. A first transmission shaft is connected to the second bevel gear. The first transmission shaft passes through the gearbox housing and is connected to the first transmission wheel. A second transmission shaft is connected to the third bevel gear. The second transmission shaft passes through the gearbox housing and is connected to the second transmission wheel.

[0010] In this invention, by setting a first transmission shaft and a second transmission shaft, the torque of the turbine and the first bevel gear can be flexibly transmitted to the second bevel gear and the third bevel gear, making the positional layout of the gearbox housing, the first gear ring and the second gear ring more flexible, and achieving miniaturization of the structural size.

[0011] Optionally, the guide groove includes two parallel and spaced annular ribs, which are obliquely arranged along the axial direction around the outer wall of the telescopic rotating cylinder. The guide member is placed between the two annular ribs. Two circular ribs are provided on each side of the two annular ribs, and the two circular ribs are in contact with the inner wall of the mounting cylinder. The circular ribs are spaced apart from the limiting groove and the annular ribs.

[0012] In this invention, two annular ribs form a guide groove with the outer wall of the telescopic rotating cylinder. The annular ribs are symmetrically arranged along any axial section of the telescopic rotating cylinder, and the annular ribs smoothly transition on the telescopic rotating cylinder. When the guide member slides relative to the guide groove, it can push the telescopic rotating cylinder to move smoothly and at a constant speed along the axial direction. The two annular ribs play a stable supporting role for the telescopic rotating cylinder.

[0013] The present invention also provides a multifunctional massager, including a shell, a top cover, a back cover, and a rotating telescopic mechanism. The rotating telescopic mechanism is disposed inside the shell. The top cover is closable and disposed on the shell corresponding to the end of the rotating cylinder. A vibration massage component is disposed inside the top cover. The back cover is closable and disposed on the shell corresponding to the end of the telescopic rotating cylinder. A first inner liner is fixed inside the rotating cylinder, and a second inner liner is fixed inside the telescopic rotating cylinder.

[0014] In this invention, the first inner liner rotates synchronously with the rotating cylinder, and the second inner liner extends, retracts, and rotates synchronously with the telescopic rotating cylinder. The vibration massage component provides vibration massage to the head end of the massage area, thereby providing different massage effects for different massage areas and improving the massage experience.

[0015] Optionally, the vibration massage assembly includes a silicone end cap, a vibration motor, and a motor housing. A fixing seat is provided on the housing, and the top cover is fixed to the silicone end cap by the fixing seat. The silicone end cap has multiple massage protrusions near the rear end of the rotating cylinder, and a covering cavity is formed at the front end of the silicone end cap away from the rotating cylinder. The motor housing is installed in the covering cavity, and the vibration motor is disposed in the motor housing and powered by a battery.

[0016] In this invention, the vibration motor drives multiple massage protrusions to generate a tremor action, thereby providing continuous vibration massage to the massage area.

[0017] Optionally, the fixing base includes a first fixing member and a second fixing member. The first fixing member is fixedly connected to the outer shell. Magnets are embedded in both the first fixing member and the second fixing member. The first fixing member and the second fixing member are magnetically rotatably connected. The silicone end cap and the top cap are both disposed on the second fixing member.

[0018] In this invention, the first fixing member and the second fixing member are used to provide a mounting base for the silicone end cap and the top cap. Since the second fixing member and the first fixing member are attracted by a magnet, when the force applied to the second fixing member exceeds the magnetic force, the second fixing member and the top cap can be rotated open to adjust different angles of the vibration massage component.

[0019] Optionally, a first fixing ring and a second fixing ring are fixedly disposed inside the outer casing, the first toothed ring is disposed between the first fixing ring and the mounting cylinder, and the second toothed ring is disposed between the second fixing ring and the mounting cylinder.

[0020] In this invention, the first fixing ring is used to limit the first gear ring and the rotating cylinder, and the second fixing ring is used to limit the ends of the second gear ring and the telescopic rotating cylinder.

[0021] Optionally, the outer casing has a first mounting hole, a push-button switch is installed in the first mounting hole, a first control panel is connected to the inside of the push-button switch, a power housing is fixedly installed inside the outer casing, a battery is installed inside the power housing, and the first control panel is located on the side of the power housing and is electrically connected to the battery.

[0022] Optionally, the outer casing has a second mounting hole, a cover plate fixing member is provided in the second mounting hole, a waterproof sealing ring is provided between the cover plate fixing member and the second mounting hole, a viewing cover plate is installed on the cover plate fixing member, a second control panel is installed on the inner side of the viewing cover plate, a light shield is provided between the viewing cover plate and the second control panel, a mounting base is provided on the cover plate fixing member, and the end of the guide member away from the guide groove is connected to the mounting base.

[0023] In this invention, a waterproof sealing ring is provided to waterproof the interior of the massager. Furthermore, rubber plugs are provided on the motor housing, power supply housing, and jaw housing to further enhance waterproofing.

[0024] Beneficial effects:

[0025] In this invention, the gears of the drive mechanism can drive the first and second gear rings meshing with them to rotate. Since the first gear ring is fixedly connected to the rotating cylinder, the rotating cylinder can rotate within the mounting cylinder. Because the second gear ring is slidably connected to the limiting groove of the telescopic rotating cylinder via a limiting protrusion, when the second gear ring rotates, the guide member and the guide groove slide relative to each other. Since the guide groove is axially offset and the position of the guide member is relatively fixed, the guide member can move the guide groove axially when the telescopic rotating cylinder rotates, meaning the telescopic rotating cylinder can also perform axial telescopic movement. This rotary telescopic mechanism can be applied to the field of massagers, providing a continuous rotary massage effect through the rotating cylinder and a reciprocating telescopic and synchronous rotation massage effect through the telescopic rotating cylinder, allowing the user to experience various massage effects and expanding the application scenarios of the rotary telescopic mechanism.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] In the description of this invention, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0040] See Figure 1 and Figure 2According to a rotary telescopic mechanism of the present invention, a rotary cylinder 1, a telescopic rotary cylinder 2, and a mounting cylinder 3 are provided. The rotary cylinder 1 and the telescopic rotary cylinder 2 are coaxially spaced within the mounting cylinder 3. A first gear ring 4 is fixedly connected to the rotary cylinder 1, and a second gear ring 5 is slidably connected to the telescopic rotary cylinder 2. A drive mechanism 6 is provided on the outer side of the mounting cylinder 3. The gear of the drive mechanism 6 meshes with the first gear ring 4 and the second gear ring 5. A limiting groove 21 is formed axially on the outer wall of the telescopic rotary cylinder 2. A limiting protrusion 51 is provided on the inner wall of the second gear ring 5, which slides with the limiting groove 21. A guide groove 22 is provided circumferentially on the outer wall of the telescopic rotary cylinder 2. The guide groove 22 is obliquely arranged axially. A guide member 31 is passed through the side wall of the mounting cylinder 3, and the inner end of the guide member 31 extends into the guide groove 22.

[0041] In this invention, the gears of the drive mechanism 6 can drive the first gear ring 4 and the second gear ring 5 meshing with it to rotate. Since the first gear ring 4 is fixedly connected to the rotating cylinder 1, the rotating cylinder 1 can rotate within the mounting cylinder 3. Since the second gear ring 5 is slidably connected to the limiting groove 21 of the telescopic rotating cylinder 2 through the limiting protrusion 51, when the second gear ring 5 rotates, the guide member 31 and the guide groove 22 slide relative to each other. Since the guide groove 22 is axially offset and the position of the guide member 31 is relatively fixed, the guide member 31 can move the guide groove 22 axially when the telescopic rotating cylinder 2 rotates, that is, the telescopic rotating cylinder 2 can also perform axial telescopic movement. The rotary telescopic mechanism of this invention can be applied to the field of massagers, providing a continuous rotary massage effect through the rotating cylinder 1 and a reciprocating telescopic and synchronous rotation massage effect through the telescopic rotating cylinder 2, allowing the massage recipient to experience a variety of different massage effects, and also expanding the application scenarios of the rotary telescopic mechanism.

[0042] See Figures 5 to 7 In some embodiments of the present invention, the drive mechanism 6 includes a gearbox housing 61, a motor 62, and a transmission gear set 63. The gearbox housing 61 is disposed on the outside of the mounting cylinder 3. The motor 62 is fixedly disposed inside the gearbox housing 61 and powered by a battery 75. The rotating shaft of the motor 62 is drivenly connected to the transmission gear set 63. The first transmission wheel 638 of the transmission gear set 63 meshes with the first gear ring 4, and the second transmission wheel 639 of the transmission gear set 63 meshes with the second gear ring 5.

[0043] In this invention, the rotation of the motor 62 is transmitted to the first gear ring 4 and the second gear ring 5 through the transmission gear set 63, eliminating the need for an additional power source and reducing production costs.

[0044] See Figure 7In some embodiments of the present invention, the transmission gear set 63 includes a worm gear 630, a worm 631, and a gear shaft 632. The worm 631 is connected to the rotating shaft of the motor 62. The gear shaft 632 is rotatably installed inside the gearbox. The worm gear 630 is sleeved on the gear shaft 632 and meshes with the worm 631. A first bevel gear 633 is sleeved on the gear shaft 632. A second bevel gear 634 and a third bevel gear 635 are meshed on the first bevel gear 633. A first transmission shaft 636 is connected to the second bevel gear 634. The first transmission shaft 636 extends out of the gearbox housing 61 and is connected to the first transmission wheel 638. A second transmission shaft 637 is connected to the third bevel gear 635. The second transmission shaft 637 extends out of the gearbox housing 61 and is connected to the second transmission wheel 639.

[0045] In this invention, by setting the first drive shaft 636 and the second drive shaft 637, the torque of the turbine 630 and the first bevel gear 633 can be flexibly transmitted to the second bevel gear 634 and the third bevel gear 635, making the positional layout of the gearbox housing 61, the first gear ring 4 and the second gear ring 5 more flexible, and realizing the miniaturization of the structural size, so as to facilitate storage and carrying.

[0046] See Figure 2 In some embodiments of the present invention, the guide groove 22 includes two parallel and spaced annular ribs 23. The two annular ribs 23 are obliquely arranged along the axial direction on the outer side wall of the telescopic rotating cylinder 2. The guide member 31 is placed between the two annular ribs 23. Two circular ribs 24 are provided on both sides of the two annular ribs 23 respectively. The two circular ribs 24 are in contact with the inner wall of the mounting cylinder 3. The circular ribs 24 are arranged between the limiting groove 21 and the annular ribs 23.

[0047] In this invention, two annular ribs 23 form a guide groove 22 with the outer wall of the telescopic rotating cylinder 2. The annular ribs 23 are symmetrically arranged along any axial section of the telescopic rotating cylinder 2, and the annular ribs 23 smoothly transition on the telescopic rotating cylinder 2, so that when the guide member 31 and the guide groove 22 slide relative to each other, the telescopic rotating cylinder 2 can be pushed to move smoothly and at a constant speed along the axial direction. The two annular ribs 24 play a stable supporting role for the telescopic rotating cylinder 2.

[0048] See Figure 3 and Figure 4According to a multifunctional massager of the present invention, a housing 7, a top cover 8, a back cover 9, and a rotating telescopic mechanism as described in any one of claims 1 to 4 are provided inside the housing 7. The top cover 8 is closable and disposed on the housing 7 at the end corresponding to the rotating cylinder 1. A vibration massage component 10 is provided inside the top cover 8. The back cover 9 is closable and disposed on the housing 7 at the end corresponding to the telescopic rotating cylinder 2. A first inner liner 11 is fixed inside the rotating cylinder 1, and a second inner liner 12 is fixed inside the telescopic rotating cylinder 2.

[0049] In this invention, the first inner liner 11 rotates synchronously with the rotating cylinder 1, and the second inner liner 12 extends, retracts, and rotates synchronously with the telescopic rotating cylinder 2. The vibration massage component 10 provides vibration massage to the head end of the massage area, thereby providing different massage effects for different massage areas and improving the massage experience.

[0050] See Figure 4 In some embodiments of the present invention, the vibration massage assembly 10 includes a silicone end cap 101, a vibration motor 102, and a motor housing 103. A fixing seat 71 is provided on the outer shell 7. The top cover 8 is fixed to the silicone end cap 101 by the fixing seat 71. The silicone end cap 101 is provided with a plurality of massage protrusions near the rear end of the rotating cylinder 1. The front end of the silicone end cap 101 away from the rotating cylinder 1 forms a covering cavity. The motor housing 103 is installed in the covering cavity. The vibration motor 102 is disposed in the motor housing 103 and powered by a battery 75.

[0051] In this invention, the vibration motor 102 drives multiple massage protrusions to generate a tremor action, thereby providing continuous vibration massage to the massage area.

[0052] See Figure 4 and Figure 5 In some embodiments of the present invention, the fixing base 71 includes a first fixing member 711 and a second fixing member 712. The first fixing member 711 is fixedly connected to the outer shell 7. Magnets 713 are embedded in both the first fixing member 711 and the second fixing member 712. The first fixing member 711 and the second fixing member 712 are magnetically rotatably connected. The silicone end cap 101 and the top cap 8 are both disposed on the second fixing member 712.

[0053] In this invention, the first fixing member 711 and the second fixing member 712 are used to provide a mounting base for the silicone end cap 101 and the top cover 8. Since the second fixing member 712 and the first fixing member 711 are attracted by the magnet 713, when the force applied to the second fixing member 712 exceeds the magnetic force, the second fixing member 712 together with the top cover 8 can be rotated open to adjust different angles of the vibration massage assembly 10.

[0054] See Figure 2 In some embodiments of the present invention, a first fixing ring 72 and a second fixing ring 73 are fixedly disposed inside the outer shell 7, the first toothed ring 4 is disposed between the first fixing ring 72 and the mounting cylinder 3, and the second toothed ring 5 is disposed between the second fixing ring 73 and the mounting cylinder 3.

[0055] In this invention, the first fixing ring 72 is used to limit the first toothed ring 4 and the rotating cylinder 1, and the second fixing ring 73 is used to limit the ends of the second toothed ring 5 and the telescopic rotating cylinder 2.

[0056] See Figure 4 and Figure 6 In some embodiments of the present invention, a first mounting hole is provided on the outer casing 7, a push button switch 74 is installed in the first mounting hole, a first control panel is connected to the inner side of the push button switch 74, a power supply housing 76 is fixedly disposed inside the outer casing 7, a battery 75 is installed inside the power supply housing 76, and the first control panel is disposed on the side of the power supply housing 76 and electrically connected to the battery 75.

[0057] In this invention, the first control panel can be connected not only to the built-in battery 75, but also to an external power source. When the battery 75 is built-in, a charging port for charging the battery 75 is provided on the outer casing 7.

[0058] See Figure 6 In some embodiments of the present invention, a second mounting hole is provided on the outer shell 7, a cover plate fixing member 77 is provided in the second mounting hole, a waterproof sealing ring is provided between the cover plate fixing member 77 and the second mounting hole, a viewing cover is installed on the cover plate fixing member 77, a second control panel is installed on the inner side of the viewing cover, a light shield 78 is provided between the viewing cover and the second control panel, a mounting base 79 is provided on the cover plate fixing member 77, and the end of the guide member 31 facing away from the guide groove 22 is connected to the mounting base 79.

[0059] In this invention, a waterproof sealing ring is provided to waterproof the interior of the massager. Furthermore, rubber plugs are provided on the motor housing 103, the power supply housing 76, and the jaw housing 61 to provide waterproofing.

[0060] When the present invention is in operation, the motor 62 is started by the button switch 74. The rotating shaft of the motor 62 drives the worm gear 631 to rotate synchronously. The worm gear 631 drives the worm 630 meshing with it to rotate, causing the wheel axle 632 and the first bevel gear 633 on it to rotate. The second bevel gear 634 and the third bevel gear 635, because they mesh with the first bevel gear 633, can drive the first transmission wheel 638 and the second transmission wheel 639 to rotate synchronously through the first transmission shaft 636 and the second transmission shaft 637, respectively. This drives the first gear ring 4 and the second gear ring 5 to rotate. Since the first gear ring 4 is fixedly connected to the rotating cylinder 1, it rotates... The cylinder 1 can rotate, and its internal first inner liner 11 provides a rotational massage effect. Since the second gear ring 5 is slidably connected to the limiting groove 21 of the telescopic rotating cylinder 2 via the limiting protrusion 51, when the second gear ring 5 rotates, the guide member 31 and the guide groove 22 slide relative to each other. Because the guide groove 22 is axially offset and the position of the guide member 31 is relatively fixed, the guide member 31 can move the guide groove 22 axially when the telescopic rotating cylinder 2 rotates. That is, the telescopic rotating cylinder 2 can not only rotate radially but also extend and retract axially, and its internal second inner liner 12 provides a rotational and telescopic massage effect. Simultaneously, the vibration motor 102 is activated, causing the multiple massage protrusions on the silicone end cap 101 to vibrate and massage. The massager of this invention can provide different massage functions according to different massage areas, making the massage effect diverse and layered, thus improving the massage experience.

[0061] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention.
