Description

Technical Field

[0001] This utility model relates to the field of medical and health care technology, and in particular to a massage device. Background Technology

[0002] With social development and the gradual improvement of living standards, people are paying more and more attention to their health and the comfort of life. Medical and health care products, such as massage devices, are becoming increasingly popular.

[0003] Most existing massage devices use a motor to drive the massage head in a linear reciprocating motion, rapidly tapping the areas of the body that need massage, such as the shoulders, neck, waist, head, and legs, to stimulate muscles and relax the mind and body. However, the interaction between the massage head and the massaged area is a point-to-point tapping motion, which has drawbacks such as a single mode of action and a small range of action, making it difficult to achieve the ideal massage effect. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a massage device that can effectively increase the range of action and improve the user experience.

[0005] To achieve the above objectives, this utility model provides a massage device, including a housing and a drive mechanism. The housing includes a massage part and a massage end, which are made of a flexible material. The drive mechanism is disposed in the housing and is connected to the massage part and the massage end for transmission. The drive mechanism is used to drive the massage part to rotate around a first axis and drive the massage end to move.

[0006] Compared with the prior art, the massage device provided by this utility model allows the massage part and massage end to act on two parts of the human body respectively during use, realizing simultaneous massage of multiple parts and effectively improving the user experience.

[0025] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. One or more embodiments of this utility model are exemplarily shown in the drawings to enable a more accurate and thorough understanding of the disclosed technical solutions. However, it should be understood that this utility model can be implemented in many different forms and is not limited to the embodiments described below.

[0026] First Embodiment

[0027] This utility model provides a massage device, mainly used for massage and relaxation of the human body. For example... Figure 1-5 The first embodiment of the massage device of this utility model is shown below. Please refer to it. Figure 1-5 The massage device 100 shown includes a housing 10 and a drive mechanism 20 disposed within the housing 10. The housing 10 is provided with a massage section 11 and a massage end 13. The drive mechanism 20 is connected to both the massage section 11 and the massage end 13. Under the action of the drive mechanism 20, the massage section 11 rotates around a first axis X1 to form a circular motion trajectory, and the massage end 13 extends and retracts along a second axis X2 to form a reciprocating linear motion trajectory. Areas of the body requiring massage and relaxation, such as the head, neck, back, waist, and legs, can continuously contact and separate from the massage section 11 within the circular trajectory range, creating a kneading stimulation. Similarly, areas within the linear motion trajectory range can continuously rub against the massage end 13, creating a kneading stimulation. In this embodiment, the massage device 100 can be used to massage two different parts of the body simultaneously, achieving simultaneous massage of multiple areas.

[0028] The massage section 11 and massage end 13, as the components of the massage device of this utility model that directly act on the human body, can be made of materials such as silicone and rubber, possessing a certain degree of flexibility. When acting on the human body, they provide a soft touch, offering a certain cushioning effect and increasing massage comfort. They also deform to some extent during movement. Of course, the massage section 11 and massage end 13 can also be made of other flexible materials that can directly contact the skin; this utility model does not impose any limitations on this. Compared to the point-to-point tapping of existing massage devices, the movement trajectory of the massage section 11 in this application is roughly circular, specifically circular, elliptical, etc., allowing for a larger effective area. Moreover, the kneading motion is similar to human hand massage, providing a more comfortable user experience. The movement trajectory of the massage end 13 is reciprocating extension and retraction, enabling reciprocating friction massage, further enhancing user comfort.

[0029] In this embodiment, the housing 10 can be a double-layer structure, including a flexible outer shell and a rigid inner shell. The inner shell provides support for internal components such as the drive mechanism 20, and the outer shell wraps around the outside of the inner shell. Specifically, the rigidity of the inner shell is greater than that of the outer shell.

[0030] Specifically, the outer shell can be composed of a main body 101 and an end cap 102. The main body 101 is hollow, with one end closed and the other end open to form a port 103. The end cap 102 covers the port 103 of the main body 101, forming a closed outer shell that houses the inner shell and components such as the drive mechanism 20. Alternatively, in another embodiment, the inner shell can be molded separately and assembled with internal components such as the drive mechanism 20, and then the outer shell can be integrally molded by injection molding. This allows the outer shell to wrap around the inner shell, providing a good sealing effect, waterproofing, and dustproofing, and facilitating cleaning and storage of the massage device 100.

[0031] In this embodiment, the housing 10 also includes a grip end, the front end of the housing 10 forms a massage end 13, and the rear end of the housing 10 forms a grip end for easy gripping by the user. The massage part 11 is located in the middle of the housing 10, that is, between the grip end and the massage end 13.

[0032] In this embodiment, the massage portion 11 is generally spherical or ellipsoidal, and the massage end 13 is generally cylindrical or frustum-shaped.

[0033] In this embodiment, the housing 10 is generally a longitudinally elongated rod-shaped structure. Specifically, a base is formed in the middle of the housing 10, one end of the massage part 11 is connected to the base as a connecting end, and the other end extends outward from the base as a free end. More specifically, the side wall of the base is concave to form a bowl-shaped portion, and the massage part 11 is disposed in the bowl-shaped portion. The connecting end of the massage part 11 is connected to the center of the bottom of the bowl-shaped portion; the free end extends outward from the open end of the bowl-shaped portion. When the massage part 11 is driven to rotate, it oscillates within the bowl-shaped portion with its connecting end as the center. Specifically, the depth of the bowl-shaped portion is less than the height of the massage part 11, so that the massage part 11 partially extends beyond the open end of the bowl-shaped portion, allowing it to easily contact the massaged area. It is understood that the base can also be other shapes, such as a columnar body flush with the gripping end or an outwardly convex bulge.

[0034] In this embodiment, the massage part 11, the massage end 13, and the rest of the outer shell are integrally molded. This injection molding of the outer shell and the massage part 11 not only simplifies production and assembly but also enhances the connection strength between the massage part 11 and the outer shell. It is understood that in other embodiments, the massage part 11 and the rest of the outer shell can also be molded separately and then connected as a single unit, allowing for selective disassembly and replacement of the massage part 11. In practical applications, the massage device 100 can be configured with multiple massage parts 11 and massage ends 13 of different structures or shapes, allowing users to select the appropriate type of massage part 11 and massage end 13 based on the desired massage location. In this case, the material of the remaining parts of the outer shell other than the massage part 11 and massage end 13 is no longer limited to the material of the massage part 11 and massage end 13; flexible materials such as silicone and rubber can be used, as well as rigid materials such as plastic and alloys.

[0035] Please refer to Figure 4 and Figure 5 The inner shell of the housing 10 includes a first part 105 corresponding to the grip end and the massage part 11, and a second part 106 corresponding to the massage end 13. The first part 105 and the second part 106 are spaced apart to form a gap 108 between them. The second part 106 is movable relative to the first part 105 along a second axis X2. Since the outer shell can deform to a certain extent, as the second part 106 moves, the outer shell surrounding the second part 106 can extend and retract along the second axis X2, thereby extending and retracting the massage end 13, and the width of the gap 108 changes accordingly. Specifically, the inner sidewall of the first part 105 is provided with two spaced supports 1051. Specifically, both the first part 105 and the second part 106 are assembled by two parts fastening together. Thus, during assembly, the drive mechanism 20 can be placed first within one part of the first part 105 and the second part 106, and then the other part of the first part 105 and the second part 106 can be fastened to the first part.

[0036] Please refer to Figure 2-5The driving mechanism 20 includes a driving assembly 22, a first driving shaft 24, and a slider 25. The driving assembly 22 is connected to the first driving shaft 24 and the slider 25, respectively, to drive the first driving shaft 24 to rotate around a first axis X1 and to drive the slider 25 to move along a second axis X2. The first driving shaft 24 includes a first connecting end 24a and a second connecting end 24b arranged at an angle to each other. The first connecting end 24a is connected to the driving assembly 22, and the second connecting end 24b is inserted into and connected to the massage part 11. The slider 25 is connected to the massage end 13. Under the action of the driving assembly 22, the massage part 11 rotates around the first connecting end 24a with the second connecting end 24b; the driving assembly 22 drives the slider 25 and the massage end 13 to move together along the second axis X2. A first vibrating element 41 and a second vibrating element 42, such as a vibration motor, can be respectively provided in the inner shell of the massage part 11 and the massage end 13, so that the massage part 11 and the massage end 13 can generate dual stimulation to the massaged area. The first vibrating element 41 rotates with the massage section 11 about the first axis X1, and the second vibrating element 42 reciprocates along the second axis X2 with the massage end 13. It is understood that, if necessary, a vibrating element may also be provided only in the inner shell of one of the massage section 11 and the massage end 13. Specifically, a perforation 109 is provided at the base of the housing 10 to allow the first drive shaft 24 to extend from inside the housing 10. Specifically, the drive shaft 227 passes through two supports 1051 and is supported by the supports 1051.

[0037] Specifically, the included angle between the first connecting end 24a and the second connecting end 24b is α1. The first connecting end 24a of the first drive shaft 24 extends along the direction of the first axis X1, and the second connecting end 24b extends along the direction of the first central axis X3. The included angle between the first axis X1 and the first central axis X3 can be β1, preferably an acute angle, and more preferably less than 45°. The included angle β1 between the first connecting end 24a and the second connecting end 24b is complementary to the included angle α1 between the first axis X1 and the first central axis X3, i.e., α1 + β1 = 180°. Thus, the deflection angle of the first central axis X3 of the massage part 11 relative to the first axis X1 can be determined by the included angle between the first connecting end 24a and the second connecting end 24b of the first drive shaft 24, thereby determining the rotation radius of the massage part 11.

[0038] Specifically, the drive assembly 22 includes a drive motor 221, a first gear 223, and a second gear 224. The first gear 223 is connected to the motor output shaft 2211 of the drive motor 221, and the second gear 224 meshes with the first gear 223. The first connecting end 24a of the first drive shaft 24 is connected to the second gear 224. The motor 221 can be a DC motor or the like, and has a high-speed rotating motor output shaft 2211. The drive motor 221 drives the first gear 223 to rotate, which in turn drives the second gear 224 to rotate, thereby driving the first drive shaft 24 to rotate as well, so that the massage part 11 can rotate around the first axis X. Specifically, in this embodiment, both the first gear 223 and the second gear 224 are bevel gears, thereby achieving the intersection of the rotation axis of the first drive shaft 24 and the rotation axis of the motor output shaft 2211 of the drive motor 22. Figure 1 In the illustrated embodiment, the gears are perpendicularly intersecting, which facilitates the spatial arrangement of the drive assembly 22, allowing the massage device 100 to be as compact and refined as possible. It is understood that the first gear 223 and the second gear 224 can also be other transmission mechanisms such as cylindrical gears or worm gears. In this case, the rotation axis of the motor output shaft 2211 of the drive motor 22 is coaxial or parallel to the rotation axis of the first drive shaft 24. Furthermore, the first gear 223 connected to the motor output shaft 2211 and the second gear 224 connected to the first drive shaft 24 can also be connected via other transmission components (such as gears), which is not limited here.

[0039] Specifically, a first drive wheel 26 is fitted onto the second connecting end 24b of the first drive shaft 24. The first drive wheel 26 has a larger radial dimension relative to the first drive shaft 24, which can better drive the massage part 11 to rotate. The massage part 11, especially the end of the massage part 11 connected to the base, can be clearance-fitted with the first drive shaft 24, so that the massage part 11 can generate sufficient deformation during rotation with the first drive shaft 24, making the rotation of the massage part 11 smoother. Preferably, the first drive wheel 26 has a first neck 27, at which the first drive wheel 26 has the smallest inner diameter. The second connecting end 24b of the first drive shaft 24 passes through the first neck 27 and forms first protrusions 28 on both axial sides of the first neck 27, the outer diameter of the first protrusions 28 being slightly larger than the inner diameter of the first neck 27. After assembly, the first protrusion 28 engages with the first neck 27, preventing the first drive wheel 26 from automatically detaching from the first drive shaft 24 without external force, thus facilitating the subsequent molding and manufacturing of the outer shell and massage part 11. Of course, the first drive wheel 26 and the first drive shaft 24 can also be fixed in other ways, such as tight fit, snap-fit, or keying, without being limited to specific embodiments.

[0040] Specifically, the drive assembly 22 further includes a third gear 225, a drive rod 227, and a pin 228. The third gear 225 meshes with the second gear 224. One end of the drive rod 227 is connected to the third gear 225, and the other end is provided with an external threaded groove 2271. The pin 228 is fixedly connected to the slider 25, and the pin 228 is movably engaged with the external threaded groove 2271, thereby forming a nut-screw structure together with the drive rod 227. The drive motor 221 drives the first gear 223, the second gear 224, and the third gear 225 to rotate sequentially, thereby driving the drive rod 227 to rotate. The pin 228 moves linearly relative to the drive rod 227 based on the nut-screw structure, thereby driving the slider 25 to move linearly. Specifically, in this embodiment, the third gear 225 is a bevel gear, so that the rotation axis of the drive rod 227 is parallel to the rotation axis of the motor output shaft 2211. Figure 1 In the illustrated embodiment, the gears overlap, which facilitates the spatial arrangement of the drive assembly 22, making the massage device 100 compact and elegant. It is understood that the third gear 225 can also be a cylindrical gear. Furthermore, the second gear 224 and the third gear 225 can be connected by other transmission components (such as gears), which is not limited here. In addition, the nut and screw structure can also be replaced by other transmission mechanisms such as a gear and rack structure, thereby converting rotation into linear movement.

[0041] Specifically, the drive assembly 22 also includes a slide rail 229 fixed relative to the massage end 13. The slide rail 229 is fitted inside the slider 25. The slide rail 229 has a groove 2291 extending along the second axis X2. The inner sidewall of the slider 25 has a protrusion 251, which is movably fitted inside the groove 2291 of the slide rail 229, so that the slider 25 can move along the groove 2291. It can be understood that the protrusion can also be provided on the slide rail 229, while the groove is provided on the slider 25.

[0042] Specifically, the slide rail 229 is fixedly connected to the second part 106. More specifically, the inner wall of the second part 106 is provided with a slot 1061. The slider 25 is provided with a pin hole 252 and a locking block 254, which is engaged in the slot 1061. The drive rod 227 includes a rod portion 2273 and a first threaded portion 2274. The rod portion 2273 is connected to the third gear 225, and the external threaded groove 2271 is provided on the first threaded portion 2274. The pin 228 includes a mating portion 2281 and a pin portion 2283. The mating portion 2281 is arc-shaped to better fit with the external threaded groove 2271. The pin portion 2283 is inserted into the pin hole 252 of the slider 25, so that when the pin 228 moves linearly, it can drive the slider 25 and the second part 106 to move together.

[0043] Specifically, the slider 25 comprises two separately manufactured parts: the insert 256 of the slider 25 and the body of the slider 25. During assembly, the mating part 2281 of the pin 228 is first inserted into the external thread groove 2271 of the first threaded part 2274 of the drive rod 227, then the first threaded part 2274 of the drive rod 227 is extended into the slide rail 229, then the slide rail 229 is inserted into the slider 25, and finally the insert 256 is fixedly connected to the body of the slider 25.

[0044] In this embodiment, the massage unit 11 and the massage end 13 are driven by the same drive motor 221, which saves costs and reduces the space occupied by the drive mechanism 20, thereby miniaturizing the massage device 100. It is understood that in another embodiment, the massage unit 11 and the massage end 13 may also be driven by two different drive motors.

[0045] In this embodiment, the gripping end of the housing 10 is provided with multiple buttons (not shown), including a power button and function keys, for user convenience. The gripping end of the housing 10 also contains control devices, such as a control circuit board 33. Button 54, through the control circuit board 33, forms a control circuit with the first vibrating element 41, the second vibrating element 42, and the drive motor 221. The user can select and adjust functions using button 54, such as adjusting the speed and direction of the drive assembly 22, and adjusting the vibration frequency of the first and second vibrating elements 41 and 42. Preferably, a battery 35, preferably a rechargeable battery, is also provided at the tail end of the housing 10. The battery 35 is electrically connected to the control circuit board 33, serving as the power source for the entire massage device 100.

[0046] Second Embodiment

[0047] Figure 6-9 The second embodiment of the massage device of this application is shown, which differs from the massage device of the first embodiment mainly in the massage end 13. In this embodiment, the massage end 13 and the gripping end are set at an angle, that is, the massage end 13 and the second axis X2 are set at an angle. Under the action of the drive mechanism 20, the massage end 13 rotates around the second axis X2 to form a circular motion trajectory.

[0048] exist Figure 6-9In the illustrated embodiment, the drive mechanism 20 includes a drive assembly 22, a first drive shaft 24, and a second drive shaft 37. The drive assembly 22 is connected to both the first drive shaft 24 and the second drive shaft 37 to drive the first drive shaft 24 to rotate around a first axis X1 and to drive the second drive shaft 37 to rotate around a second axis X2. The first drive shaft 24 includes a first connecting end 24a and a second connecting end 24b arranged at an angle to each other. The first connecting end 24a is connected to the drive assembly 22, and the second connecting end 24b is connected to the massage part 11. The second drive shaft 37 includes a third connecting end 37a and a fourth connecting end 37b arranged at an angle to each other. The third connecting end 37a is connected to the drive assembly 22, and the fourth connecting end 37b is connected to the massage end 13. Under the action of the drive assembly 22, the massage part 11 rotates around the first connecting end 24a with the second connecting end 24b; the massage end 13 rotates around the third connecting end 37a with the fourth connecting end 37b. Specifically, the first connecting end 24a is connected to the second gear 224, and the third connecting end 37a is connected to the third gear 225. Specifically, in this embodiment, the first axis X1 is perpendicular to the second axis X2. It can be understood that in other embodiments, the first axis X1 may also be tilted at a certain angle relative to the second axis X2.

[0049] In this embodiment, specifically, a second drive wheel 38 with a larger radial dimension relative to the second drive shaft 37 is fitted onto the fourth connecting end 37b of the second drive shaft 37, which can better drive the massage end 13 to rotate. A connecting block 132 is provided inside the massage end 13, and the second drive wheel 38 is connected to the connecting block 132. When the second drive shaft 37 rotates around the second axis X2, it drives the connecting block 132 to rotate. The connecting block 132 has a receiving groove for accommodating the second drive wheel 38, and the connecting block 132 and the second drive wheel 38 can be in a spherical fit. Specifically, the connecting block 132 can be connected to the inner shell of the housing 10. Preferably, the second drive wheel 38 has a second neck 39, where the first drive wheel 26 has the smallest inner diameter. The fourth connecting end 37b of the second drive shaft 37 passes through the second neck 39 and forms second protrusions 40 on both axial sides of the second neck 39, the outer diameter of the second protrusions 40 being larger than the inner diameter of the second neck 39. Of course, the second drive wheel 38 and the connecting block 132 can also be fixed in other ways, such as tight fit, snap-fit, keying, etc., without being limited to specific embodiments.

[0050] Specifically, the included angle between the third connecting end 37a and the fourth connecting end 37b is α2. The third connecting end 37a of the second drive shaft 37 extends along the direction of the second axis X2, and the fourth connecting end 37b extends along the direction of the second central axis X4. The included angle between the second axis X2 and the second central axis X4 can be β2, preferably an acute angle, and more preferably less than 45°. The included angle β2 between the third connecting end 37a and the fourth connecting end 37b is complementary to the included angle α2 between the second axis X2 and the second central axis X4, i.e., α2 + β2 = 180°. Thus, the deflection angle of the second central axis X4 of the massage end 13 relative to the second axis X2 can be determined by the included angle between the third connecting end 37a and the fourth connecting end 37b of the second drive shaft 37, thereby determining the rotation radius of the massage end 13.

[0051] The other structures in this embodiment are the same as those in the first embodiment, and will not be described again here.

[0052] Third Embodiment

[0053] Figure 10-13 The image shown is a third embodiment of the massage device of this application. Its main difference from the massage device of the first embodiment lies in the massage end 13 and the gripping end. Please refer to... Figure 10-13 In this embodiment, the massage end 13 and the grip end are angled, that is, the massage end 13 and the second axis X2 are angled. Under the action of the drive mechanism 20, the massage end 13 rotates around the fifth axis X5 perpendicular to the massage end 13 to form an arc-shaped reciprocating motion trajectory. The grip end is bent at a certain angle toward one side of the massage device to form a handle 15, thereby making the massage device generally "L" shaped. Specifically, a third vibrating element 43 (e.g., a vibration motor) can be provided inside the handle 15, so that the entire massage device can vibrate, thereby enabling the massage part 11 and the massage end 13 to provide dual stimulation to the massaged area. When using the massage device 100, the "L" shaped structure of the massage device 100 is more convenient for the user to hold. It can be understood that in another embodiment, a support is also provided on the grip end on the opposite side from the handle 15, thereby making the massage device generally "T" shaped.

[0054] exist Figure 10-13In the illustrated embodiment, the drive mechanism 20 includes a drive assembly 22, a first drive shaft 24, and a swing block 53. The drive assembly 22 is connected to both the first drive shaft 24 and the swing block 53 to drive the first drive shaft 24 to rotate around a first axis X1 and to drive the swing block 53 to rotate around a fifth axis X5. The first drive shaft 24 includes a first connecting end 24a and a second connecting end 24b arranged at an angle to each other. The first connecting end 24a is connected to the drive assembly 22, and the second connecting end 24b is connected to the massage part 11. The swing block 53 is connected to the massage end 13. Under the action of the drive assembly 22, the massage part 11 rotates around the first connecting end 24a with the second connecting end 24b, forming a roughly circular trajectory, which can create a kneading effect on a larger area of ​​the massaged part; the massage end 13 rotates around the third connecting end 37a with the fourth connecting end 37b, forming a roughly arc-shaped motion trajectory, which can create a kneading effect on a larger area of ​​the massaged part.

[0055] Specifically, the drive mechanism 20 further includes a third drive shaft 54 ​​and an eccentric wheel 55. The third drive shaft 54 ​​is connected to the drive assembly 22 and is rotatable about the second axis X2. The eccentric wheel 55 is connected to the third drive shaft 54 ​​to rotate with the third drive shaft 54 ​​about the second axis X2. The eccentric wheel 55 includes an eccentric block 551 offset from the second axis X2. The swing block 53 includes two spaced-apart forked blocks 531 to form a slot 533 between the two forked blocks 531. The eccentric block 551 is located within the slot 533, and the width of the eccentric block 551 is smaller than the width of the slot 533, so that the eccentric block 551 can only selectively contact one of the two forked blocks 531. The distance D1 of the eccentric block 551 offset from the second axis X2 is greater than the difference D2 between the width of the eccentric block 551 and the width of the slot 533, so that the eccentric block 551 can push the swing block 53 to rotate about the fifth axis X5 when rotating. As the eccentric wheel 55 rotates, the eccentric block 551 swings around the fifth axis X5 in the slot 533. Specifically, the swing block 53 is rotatably sleeved on the rotating shaft 57 arranged along the fifth axis X5, so that the swing block 53 can rotate around the fifth axis X5.

[0058] Fourth embodiment

[0059] Figure 14-17 The image shown is a fourth embodiment of the massage device of this application, which differs from the massage device of the first embodiment mainly in the drive mechanism 20. Please refer to... Figure 10-13 The massage device 100 shown includes a housing 10 and a drive mechanism 20 disposed within the housing 10. The housing 10 has a massage section 11 and a massage end 13. The drive mechanism 20 is driveably connected to the massage section 11 and to one end of the base and the gripping end. Under the action of the drive mechanism 20, the massage section 11 rotates around a first axis X1 to form a circular motion trajectory, and the massage section 11 and the massage end 13 extend and retract along a second axis X2 to form a reciprocating linear motion trajectory. Specifically, in this embodiment, the first part 105 corresponds to the gripping end, and the second part 106 corresponds to the massage section 11 and the massage end 13.

[0060] In this embodiment, the driving mechanism 20 includes a driving component 22, a first driving shaft 24, and a slider 25. The driving component 22 is connected to the first driving shaft 24 and the slider 25 respectively, driving the first driving shaft 24 to rotate around the first axis X1 and driving the slider 25 to move along the second axis X2. The first driving shaft 24 includes a first connecting end 24a and a second connecting end 24b arranged at an angle to each other, wherein the first connecting end 24a is connected to the driving component 22, and the second connecting end 24b is connected to the massage part 11. The slider 25 is connected to the end connected to the base and the gripping end. Under the action of the driving component 22, the massage part 11 rotates around the first connecting end 24a with the second connecting end 24b, forming a roughly circular trajectory, which can create a kneading effect on a larger area of ​​the massaged part; the driving component 22 drives the slider 25, the massage part 11, and the massage end 13 to move together along the second axis X2, with the reciprocating movement of the slider 25. In this embodiment, since the slider 25 is connected to the end of the bowl-shaped part that is connected to the gripping end, it can drive the massage part 11, the massage end 13, and the bowl-shaped part to extend and retract as a whole.

[0061] Specifically, the drive assembly 22 includes a drive motor 221, a first gear 223, and a second gear 224. The first gear 223 is connected to the motor output shaft 2211 of the drive motor 221, and the second gear 224 meshes with the first gear 223. The first drive shaft 24 is connected to the second gear 224. The motor 221 can be a DC motor or the like, and has a high-speed rotating motor output shaft 2211. The drive motor 221 drives the first gear 223 to rotate, which in turn drives the second gear 224 to rotate, thereby driving the first drive shaft 24 to rotate as well, so that the massage part 11 can rotate around the first axis X. Specifically, in this embodiment, both the first gear 223 and the second gear 224 are bevel gears, thereby achieving the intersection of the rotation axis of the first drive shaft 24 and the rotation axis of the motor output shaft 2211 of the drive motor 22. Figure 1 In the illustrated embodiment, the gears are perpendicularly intersecting, which facilitates the spatial arrangement of the drive assembly 22, making the massage device 100 compact and elegant. It is understood that the first gear 223 and the second gear 224 can also be cylindrical gears, in which case the rotation axis of the motor output shaft 2211 of the drive motor 22 is coaxial or parallel to the rotation axis of the first drive shaft 24. Furthermore, the first gear 223 connected to the motor output shaft 2211 and the second gear 224 connected to the first drive shaft 24 can also be connected via other transmission components (e.g., gears), which is not limited here.

[0062] Specifically, the drive assembly 22 also includes a second threaded portion 230 and a pin 228. The second threaded portion 230 is connected to the motor output shaft 2211 and has an external threaded groove 2271. The pin 228 is fixedly connected to the slider 25 and is movably engaged with the external threaded groove 2271, thereby forming a nut-screw structure together with the second threaded portion 230. When the drive motor 221 operates, it drives the second threaded portion 230 to rotate. The pin 228 moves linearly relative to the second threaded portion 230 based on the nut-screw structure, thereby driving the slider 25 to move linearly. It can be understood that the nut-screw structure can also be replaced by a gear and rack structure to convert rotation into linear movement.

[0063] Specifically, the drive assembly 22 also includes a slide rail 229 fixed relative to the first part 105, and the slide rail 229 is sleeved inside the slider 25. It can be understood that the structure of the slide rail 229 and the slider 25 in this embodiment is the same as that in the first embodiment, and will not be described again here.

[0064] The other structures in this embodiment are the same as those in the first embodiment, and will not be described again here.

[0065] Please refer to Figure 15 When the massage device 100 is in the retracted state, the massage part 11 and the massage end 13 are close to the grip end, and the gap 108 is small; please refer to Figure 18 When the friction device 100 is in the extended state, the massage part 11 and the massage end 13 extend toward the end away from the gripping end, and the gap 108 increases.

[0066] It should be noted that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, such as combining different features in various embodiments, and these should all fall within the protection scope of the present invention.
