[0012] In some embodiments of this application, the sleeve is movably disposed on the housing, and the direction of movement of the sleeve is consistent with the extension direction of the accommodating cavity in the housing.

[0013] In some embodiments of this application, the hand massager further includes a drive motor, a lead screw connected to the drive shaft of the drive motor, and a connecting kit disposed on the lead screw; the outer wall of the lead screw is provided with an external thread, the connecting kit is sleeved on the outside of the lead screw, and the inner wall of the connecting kit is provided with an internal thread adapted to be screwed into the external thread. The connecting kit is fixed to the sleeve, the axis of the lead screw is aligned with the extension direction of the receiving cavity, and the drive motor can drive the lead screw to rotate around its own axis so that the sleeve can follow the connecting kit, thereby causing the sleeve to reciprocate in the extension direction of the receiving cavity.

[0014] In some embodiments of this application, the sleeve is provided in multiple forms, and the hand massager further includes a movable plate, with the multiple sleeves fixed on the movable plate, and the movable plate being connected and fixed to the connecting kit.

[0015] In some embodiments of this application, the hand massager further includes a travel limiting member disposed in the receiving cavity; the travel limiting member is provided with a travel groove, the length direction of the travel groove being consistent with the extension direction of the receiving cavity; The end of the movable plate is movably disposed in the travel groove, and the two sides of the movable plate can respectively abut against the inner walls of the two sides of the travel limiting member in the length direction of the travel groove.

[0016] In some embodiments of this application, the hand massager further includes a position sensor, which is fixedly disposed on the inner wall of the accommodating cavity of the housing and is electrically connected to the drive motor; The position sensor is used to detect the position of the sleeve in the extension direction of the accommodating cavity, and can generate a position detection signal and feed it back to the drive motor. The drive motor can control the sleeve to reciprocate within a preset stroke range according to the position detection signal.

[0017] In some embodiments of this application, the hand massager further includes a back-of-hand massage component disposed in the accommodating cavity, the surface of which is used to contact the back of the user's hand; the back-of-hand massage component has a hollow cavity inside, which is used to inflate the back-of-hand massage component to expand it.

[0018] In some embodiments of this application, the hand massager further includes a first palm massager disposed in the receiving cavity, and the surface of the first palm massager is used to abut against at least a portion of the user's palm. The first palm massager has a hollow cavity inside, which is used to inflate the first palm massager.

The second palm massager includes a base and a massage head protruding from the base. The massage head is used to abut against at least a portion of the user's palm. The base is rotatably disposed on the housing, and the direction of the rotation axis of the base is perpendicular to the extension direction of the accommodating cavity.

[0020] In some embodiments of this application, the hand massager includes a rotary motor and a transfer shaft connected to the power shaft of the rotary motor. The transfer shaft is connected to the seat body, and the rotary motor can drive the transfer shaft to rotate, so that the seat body rotates relative to the housing.

[0021] In some embodiments of this application, the power shaft of the rotating motor is a screw structure with threads on the outer wall, and a driven gear is sleeved on the outside of the adapter shaft; the hand massager also includes a gear transmission assembly, which includes at least two transmission gears of different sizes, and the different transmission gears mesh with each other; The power shaft has gear teeth that are adapted to the transmission gear.

[0022] As can be seen from the above technical solution, the beneficial effects of the present invention are as follows: For the hand massager of this application, the air chamber of the sleeve can be inflated to expand the sleeve. The expanded sleeve can exert a gentle kneading force on the fingers inside, and can evenly squeeze the fingertips, knuckles, and sides of the fingers, effectively promoting blood circulation in the fingers. Furthermore, the squeezing force of the sleeve on the fingers can be flexibly adjusted by the amount of air to suit the massage intensity needs of different users, ensuring the suitability and safety of the massage. In addition, the ball bearings are set on the inner wall of the sleeve and can rotate relative to each other. On the one hand, when the air chamber is inflated, it will push the ball bearings to come into close contact with the surface of the fingers. Slight hand movements or the ball bearings rolling naturally with the squeezing force will form a dynamic and gentle rolling massage, improving the comfort of the massage. On the other hand, the point-contact massage of the ball bearings can accurately act on the acupoints and meridians of the fingers, stimulating key points of the fingers, effectively relieving finger muscle tension and hand nerve fatigue.

[0023] The hand massager of this application can achieve a comprehensive massage of the hand fingers by combining sleeve and roller, which is more in line with the physiological structure of the hand and the actual needs of users to relieve fatigue, so as to achieve deep hand relaxation and enhance the overall effect of massage.

[0038] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0039] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] See Figures 1 to 3 One embodiment of this application provides a hand massager 100, which includes a housing 10, a sleeve 20, and a ball bearing 30.

[0042] The housing 10 has an internal cavity 101 for inserting and placing a user's hand. Several sleeves 20 are provided, each disposed within the cavity 101, and each sleeve 20 can be fitted over the outside of a finger. Each sleeve 20 has an air chamber for inflation. A ball bearing 30 is disposed on the inner wall of each sleeve 20, and the ball bearing 30 can rotate relative to the sleeve 20, abutting against the surface of the finger.

[0043] In the hand massager 100 of this application, the air chamber of the sleeve 20 can be inflated to expand the sleeve 20. The expanded sleeve 20 can exert a gentle kneading force on the fingers inside, providing uniform surface compression to the fingertips, knuckles, and sides of the fingers, effectively promoting blood circulation in the fingers. Furthermore, the squeezing force of the sleeve 20 on the fingers can be flexibly adjusted by the inflation volume to suit the massage intensity needs of different users, ensuring the suitability and safety of the massage. In addition, the ball bearings 30 are disposed on the inner wall of the sleeve 20 and can rotate relative to it. On the one hand, when the air chamber is inflated, it pushes the ball bearings 30 to come into close contact with the finger surface. Slight hand movements or the natural rolling of the ball bearings 30 under the squeezing force create a dynamic and gentle rolling massage, enhancing the comfort of the massage. On the other hand, the point-contact massage of the ball bearings 30 can precisely target acupoints and meridians on the fingers, stimulating key points on the fingers, effectively relieving finger muscle tension and alleviating hand nerve fatigue.

[0044] The hand massager 100 of this application can achieve a comprehensive massage of the hand fingers by combining the sleeve 20 and the ball bearing 30, which is more in line with the physiological structure of the hand and the actual needs of the user to relieve fatigue, so as to achieve deep hand relaxation and enhance the overall effect of the massage.

[0045] In some embodiments of this application, such as Figure 4 and Figure 5As shown, the housing 10 may include an outer shell 11 and an inner shell 12 disposed inside the outer shell 11. The outer shell 11 includes an upper shell 111 and a lower shell 112 that are interlocked vertically, forming an installation space. The inner shell 12 is disposed within the installation space of the outer shell 11, and the bottom of the lower shell 112 has a raised base, enabling stable placement of the hand massager 100 on a tabletop.

[0046] In some examples, the inner shell 12 may include a rear shell 121 and a front shell support 122 connected to the rear shell 121. Both the rear shell 121 and the front shell support 122 are open at both ends and hollow inside. The rear shell 121 communicates with the opening at one end of the front shell support 122, and the interior of the rear shell 121 is in communication with the interior of the front shell support 122, together forming the receiving cavity 101 of the shell 10. The user's hand can be placed in the receiving cavity 101 of the shell 10 through the rear shell 121 away from the opening at one end of the front shell support 122.

[0047] In this example, the rear shell 121 and the front shell bracket 122 can be fastened together by screws. The rear shell 121 can be locked to the upper shell 111 and the lower shell 112 by screws, and the front shell bracket 122 can be locked to the upper shell 111 and the lower shell 112 by screws, so as to ensure the stability of the overall structure of the shell 10.

[0048] Combination Figure 6 , Figure 7 by Figure 8 As shown in this application, the housing 10 has a plurality of sleeves 20 inside the accommodating cavity 101, which can be fitted onto the outside of a finger. The sleeve 20 has an air chamber for inflation to expand the sleeve 20.

[0049] In some embodiments of this application, four sleeves 20 are provided, arranged side by side inside the front housing support 122, with the openings of the four sleeves 20 located near the end of the front housing support 122 away from the rear housing 121. The four sleeves 20 can respectively accommodate the index finger, middle finger, ring finger, and little finger of the hand, and the extending direction of the sleeves 20 is consistent with the extending direction of the receiving cavity 101. When the user's hand is inserted into the receiving cavity 101, it can be ensured that the index finger, middle finger, ring finger, and little finger can be smoothly accommodated in the four sleeves 20 respectively.

[0050] In some examples, there may be five sleeves 20. Four of the sleeves 20 are arranged side by side and are used to accommodate the index finger, middle finger, ring finger and little finger of the hand, respectively; the other sleeve 20 is arranged at an angle to the four side by side sleeves 20 and is used to accommodate the thumb of the hand.

[0051] In this embodiment, the hand massager 100 may further include a mounting base 41, on which a mounting position 410 is provided. The mounting base 41 is fixed to the inner wall of the sleeve 20, and the ball bearing 30 is rotatably disposed at the mounting position 410 of the mounting base 41.

[0052] In some examples, the base can be thermocompressed to the sleeve 20. The sleeve 20 can be made of flexible materials such as silicone or TPE, while the base can be made of rigid materials such as rigid plastic or rigid silicone. Thermocompressing allows the interface between the two materials to partially melt at high temperatures, forming a molecular-level bond and enhancing the stability of the connection between the base and the sleeve 20.

[0053] In other examples, the base may also be elastic, such as being made of an elastic material. The base is fixed to the sleeve 20. When the sleeve 20 is inflated, the base can deform accordingly to prevent the inflated sleeve 20 from pulling on the base, thus preventing the base from falling off the sleeve 20 and ensuring the stability of the base assembly on the sleeve 20.

[0054] like Figure 9 As shown, in some embodiments of this application, the mounting base 41 may include an inner mounting plate 411 and an outer mounting plate 412, which are respectively connected to the inner and outer sides of the sleeve 20. The inner mounting plate 411 and the outer mounting plate 412 are fastened with screws to clamp the inner and outer sides of the sleeve 20.

[0055] The mounting base 41 may further include a ball seat 413, which has a groove. The inner mounting plate 411 has several mounting holes, and the ball seat 413 is disposed at the mounting holes and protrudes from the inner mounting plate 411. The groove of the ball seat 413 forms the mounting position 410 of the mounting base 41, and the ball 30 is rotatably disposed in the groove of the ball seat 413, protruding from the edge of the ball seat 413.

[0056] In this embodiment, the sleeve 20 can be made of a rigid material, and the inner mounting plate 411 can be integrally formed with the sleeve 20. The inner mounting plate 411 has a mounting opening corresponding to the outer side of the sleeve 20, through which the ball bearing 30 can be mounted on the sleeve 20. A cover plate is provided at the mounting opening of the inner mounting plate 411 to prevent the ball bearing 30 from falling out.

[0057] In other embodiments, the sleeve 20 may be made of a flexible material, such as plastic, silicone, or rubber. The mounting base 41 is made of a material with a certain structural rigidity. The mounting base 41 can provide a stable and rigid rotational support for the ball bearing 30, avoiding problems such as jamming, displacement, or loosening of the ball bearing 30 caused by the flexible deformation of the sleeve 20 due to the inflation and expansion of the air chamber. Structurally, this ensures that the ball bearing 30 always maintains a smooth rotational state.

[0058] In some examples, the extension direction of the mounting base 41 may be consistent with the axial direction of the sleeve 20, and the mounting base 41 may be provided with multiple mounting positions 410, which are arranged at intervals along the extension direction of the mounting base 41.

[0059] The extension direction of the mounting base 41 is consistent with the axial direction of the sleeve 20, allowing the mounting base 41 to be set along the longitudinal direction of the finger, so that the arrangement direction of the multiple mounting positions 410 conforms to the physiological extension direction of the finger. This arrangement allows the rollers 30 to be arranged sequentially along the longitudinal direction of the finger (fingertip, middle finger, knuckle, base of finger, etc.), achieving full coverage of the entire length of a single finger and ensuring full-area rolling massage along the longitudinal direction of the finger.

[0060] In some embodiments of this application, the sleeve 20 is provided with a plurality of mounting bases 41 inside, and the plurality of mounting bases 41 can be arranged circumferentially around the axis of the sleeve 20.

[0061] The sleeve 20 has a cylindrical structure with multiple mounting bases 41 arranged circumferentially around its axis. This arrangement allows the ball bearings 30 on each mounting base 41 to correspond to different circumferential positions of the finger, achieving full-coverage massage of the entire finger and ensuring precise and soothing massage for all fingers.

[0062] Furthermore, when the air chamber of the sleeve 20 is inflated, the multiple rollers 30 on the mounting base 41 can generate a squeezing force in the circumference of the finger, allowing the finger to obtain a uniform rolling and kneading experience in the entire circumference while being squeezed in the overall circumference. This ensures the massage intensity while avoiding excessive local pressure, greatly reducing the discomfort caused by hard contact or single-point pressure, and improving the comfort and safety of the massage.

[0063] In some examples, each sleeve 20 may have three sets of mounting bases 41 inside, with the three sets of mounting bases 41 arranged at a 120° angle between each other on the inner wall of the sleeve 20.

[0064] The three sets of mounting bases 41 are arranged at a 120° angle between each other, which can accurately cover the three core areas where finger fatigue and stress are concentrated, namely the fingertip, the left side of the finger, and the right side of the finger. This allows the massage force of the roller ball 30 to be concentrated on the areas where finger fatigue is most likely to occur, greatly improving the targeting and soothing effect of the massage.

[0065] Furthermore, the lines connecting the three sets of mounting bases 41 can form an equilateral triangle. This triangular support structure can be adapted to the cylindrical physiological structure of the fingers, making the circumferential force on the fingers gentler and more even. Combined with the inflation and expansion setting of the sleeve 20, it can eliminate the discomfort of excessive kneading massage at a single point, effectively improving the fit and comfort of the hand massager 100.

[0066] See some examples. Figure 10 Each sleeve 20 can be provided with two sets of mounting bases 41 inside, and the two sets of mounting bases 41 can be arranged vertically opposite each other in the height direction of the housing 10.

[0067] The symmetrical arrangement of the two sets of mounting bases 41, positioned vertically opposite each other, creates an axisymmetric support structure on the inner wall of the sleeve 20. This arrangement ensures that when the air chamber is inflated and compressed, the rollers 30 on the two sets of mounting bases 41 will simultaneously and with equal force contact the upper and lower parts of the fingers, forming opposing point-to-point rolling forces. This not only ensures even force distribution around the fingers, completely avoiding the discomfort caused by localized stress concentration at a single point, but also allows the fingers to naturally remain in the center of the sleeve 20 through the opposing contact forces, preventing circumferential displacement or movement during the massage. This ensures that the rollers 30 always effectively contact the finger surface, significantly improving the consistency and stability of the massage.

[0068] In other examples, the multiple mounting bases 41 inside each sleeve 20 can also be arranged in a cross-shaped, quadrangular, or symmetrical manner.

[0069] In other embodiments, the mounting base 41 may be omitted. In these embodiments, the sleeve 20 may include an outer cylinder and an inner cylinder disposed inside the outer cylinder, the inner cylinder having an air cavity. The outer cylinder is made of a rigid material, and the inner cylinder is made of a flexible material. A sandwich is formed between the outer cylinder and the inner cylinder, and ball bearings 30 are disposed in the sandwich.

[0070] The outer cylinder is made of a rigid material, which can stably maintain the cylindrical finger-like shape of the sleeve 20, providing a fixed movement space for the interlayer and the ball bearings 30, and preventing the sleeve 20 from deforming as a whole due to inflation or hand compression. The inner cylinder has an air cavity and is made of a flexible material. When inflated, it expands flexibly inward (i.e., towards the fingers), directly pushing the ball bearings 30 in the interlayer to make tight contact with the finger surface.

[0071] The roller ball 30 has no fixed mounting position 410. It can roll freely along the longitudinal and circumferential direction of the finger in the interlayer. The air thrust of the inner cylinder and the natural slight movement of the finger will drive the roller ball 30 to achieve dynamic rolling massage on the finger surface, eliminating possible small massage blind spots such as gaps between knuckles and edges of fingertips, and achieving rolling and soothing of the entire finger area.

[0072] like Figure 11 and Figure 12 As shown, in some embodiments of this application, the sleeve 20 is movably disposed on the housing 10, and the moving direction of the sleeve 20 is consistent with the extending direction of the accommodating cavity 101 in the housing 10.

[0073] The movable design of the sleeve 20 allows for a dynamic adjustment of the massage area. Moving the sleeve 20 towards the fingertips enables precise rolling massage of the fingertips and the front part of the finger pads; moving it towards the palm heel covers the base of the fingers and metacarpophalangeal joints, achieving comprehensive, coordinated massage of the finger-palm connection. Combined with the expansion of the sleeve 20 and the rotating and pressing massage of the ball bearing 30, the actual massage effect is significantly enhanced.

[0074] In some examples, the hand massager 100 may also include a drive motor 42, a lead screw 43 connected to the drive shaft of the drive motor 42, and a connecting kit 44 disposed on the lead screw 43. The outer wall of the lead screw 43 is provided with external threads, the connecting kit 44 is sleeved on the outside of the lead screw 43, and the inner wall of the connecting kit 44 is provided with internal threads adapted to be screwed into the external threads.

[0075] The connecting kit 44 is fixed to the sleeve 20. The axis of the lead screw 43 is aligned with the extension direction of the receiving cavity 101. The drive motor 42 can drive the lead screw 43 to rotate around its own axis so that the sleeve 20 can follow the connecting kit 44, thereby causing the sleeve 20 to reciprocate in the extension direction of the receiving cavity 101.

[0076] In other examples, the hand massager 100 may include a cylinder, the piston rod of which extends in the same direction as the extension of the receiving cavity 101. A sleeve 20 is attached to the end of the piston rod, and the linear extension and retraction of the piston rod enables the sleeve 20 to reciprocate in the extension direction of the receiving cavity 101.

[0077] Alternatively, the hand massager 100 may include a linear motor, the power drive shaft of which is connected and fixed to the sleeve 20. The operation of the linear motor can drive the sleeve 20 to perform linear reciprocating movement, thereby causing the sleeve 20 to reciprocate in the extending direction of the receiving cavity 101.

[0078] Alternatively, a driving synchronous pulley and a driven synchronous pulley can be respectively installed at both ends of the housing 10, with the driving synchronous pulley connected to the output shaft of the motor. The synchronous belt is wound around the two synchronous pulleys and kept taut. The sleeve 20 can be fixed to the synchronous belt. The motor drives the driving synchronous pulley to rotate, and the rotation of the synchronous pulley is converted into the linear reciprocating movement of the sleeve 20 through the transmission of the synchronous belt.

[0079] See Figure 11 In some embodiments of this application, multiple sleeves 20 may be provided, such as four or five as described above. The hand massager 100 may also include a movable plate 45, on which multiple sleeves 20 are fixed, and the movable plate 45 is connected and fixed to the connecting kit 44.

[0080] Multiple sleeves 20 can correspond to multiple fingers of the user, and the moving plate 45 can integrate the transmission connection of multiple sleeves 20 to realize the synchronous reciprocating movement of multiple sleeves 20, which simplifies the overall structural setting of the device and improves the coordination of the hand massager 100.

[0081] In some examples, combined Figure 5 and Figure 12 As shown, a window 1220 is provided on the front shell bracket 122, and a pin 46 is provided at the bottom of the movable plate 45. The pin 46 extends into the interior of the front shell bracket 122 through the window 1220, and the movable plate 45 is arranged at the window 1220 of the front shell bracket 122. A connecting kit 44 is provided on the side of the movable plate 45 opposite to the pin 46, and the connecting kit 44 is arranged on the outside of the front shell bracket 122.

[0082] The hand massager 100 may further include a travel limit member 47 disposed in the receiving cavity 101. The travel limit member 47 may be disposed at the window 1220 of the front housing bracket 122. The travel limit member 47 has a travel groove 471, the length direction of which is consistent with the extension direction of the receiving cavity 101. The end of the movable plate 45 is movably disposed in the travel groove 471, and both sides of the movable plate 45 can respectively abut against the inner walls of the travel limit member 47 corresponding to the travel groove 471 along its length direction.

[0083] The travel limiter 47 can limit the maximum forward and backward movement distance of the sleeve 20 along the receiving cavity 101, preventing the sleeve 20 from moving excessively into the receiving cavity 101 and hitting the inner wall of the housing 10, which could lead to the sleeve 20 becoming loose, the air chamber being damaged, or the ball bearing 30 getting stuck. It can also prevent the sleeve 20 from moving excessively outward and pulling on the fingers, causing discomfort, or causing the sleeve 20 to detach from the fingers and lose its massage effect, ensuring that the sleeve 20 always moves within the effective massage stroke and ensuring the massage effect.

[0084] In some examples, the hand massager 100 may also include a position sensor 48, which is fixedly disposed on the inner wall of the accommodating cavity 101 of the housing 10 and electrically connected to the drive motor 42.

[0085] The position sensor 48 is used to detect the position of the sleeve 20 in the extending direction of the accommodating cavity 101, and can generate a position detection signal and feed it back to the drive motor 42. The drive motor 42 can control the sleeve 20 to reciprocate within a preset stroke range according to the position detection signal.

[0086] The position sensor 48 can be a Hall sensor, photoelectric sensor, displacement sensor, etc. The drive motor 42 can be controlled to rotate a certain number of revolutions and at a certain angle based on the position detection signal transmitted by the position sensor 48, thereby improving the control accuracy of the movement stroke of the sleeve 20.

[0087] In some embodiments of this application, such as Figure 11 As shown, the sleeve 20 may be provided with an air nozzle 51 that communicates with the air chamber. The hand massager 100 also includes an air pump 52 and an air valve 53. The air pump 52 is connected to the air nozzle 51 through the air valve 53 to control the filling and releasing of gas inside the air chamber.

[0088] In this embodiment, the bottom of the front housing bracket 122 is provided with a mounting groove 1221, and the air pump 52 is fixed to the bottom of the front housing bracket 122 by a mounting bracket 123. The air valve 53 can be set at the top of the front housing bracket 122, and the air valve 53 can be connected to the air nozzle 51 on the sleeve 20 and the air pump 52 through a pipeline.

[0089] See some examples. Figure 11 The hand massager 100 may also include a back-of-hand massage element 60. The back-of-hand massage element 60 is disposed in the receiving cavity 101, and the lower surface of the back-of-hand massage element 60 is used to abut against the back of the user's hand. The back-of-hand massage element 60 has a hollow cavity inside, which is used to inflate the back-of-hand massage element 60.

[0090] The back-of-hand massager 60 is arranged in the accommodating cavity 101 with its lower surface conforming to the back of the hand. After its inflatable cavity expands, it can form a uniform pneumatic compression on the entire back-of-hand area, complementing the massage of the sleeve 20 on the fingers. This can eliminate blind spots in the back-of-hand massage, thereby relieving fatigue in both the fingers and the back of the hand at the same time. This greatly enhances the practical value of the hand massager 100 for relaxing the entire hand and makes it suitable for a wider range of hand fatigue relief scenarios.

[0091] In this example, the back-of-hand massager 60 may be equipped with a back-of-hand air nozzle 61, which is connected to the cavity of the back-of-hand massager 60. The air pump 52 inside the housing 10 can be connected to the back-of-hand air nozzle 61 through a pipeline to realize the inflation and deflation of the internal cavity of the back-of-hand massager 60.

[0092] In some embodiments of this application, such as Figure 11 and Figure 13 As shown, the hand massager 100 also includes a first palm massager 71, which is disposed in the receiving cavity 101. The surface of the first palm massager 71 is used to contact at least a portion of the user's palm. The first palm massager 71 has a hollow cavity inside, which is used to inflate the first palm massager 71.

[0093] In this embodiment, the hand massager 100 may further include a second palm massager 72 disposed inside the accommodating cavity 101. The second palm massager 72 includes a base 721 and a massage head 722 protruding from the base 721. The massage head 722 is used to abut against at least a portion of the user's palm. The base 721 is rotatably disposed on the housing 10, and the direction of the rotation axis of the base 721 is perpendicular to the extension direction of the accommodating cavity 101.

[0094] In this embodiment, the second palm massager 72 can be positioned at the center of the palm, and the first palm massager 71 can be arranged around the second palm massager 72. When the first palm massager 71 is inflated, it can provide pressure massage to the palm, and the massage head 722 of the second palm massager 72 can perform rotational kneading massage on the palm. The two massage structures can work together to improve the comfort of the palm massage.

[0095] The hand massager 100 may also include a palm air valve 711. The air pump 52 can be connected to the first palm massage element 71 through a pipeline. The palm air valve 711 is located on the pipeline between the air pump 52 and the first palm massage element 71.

[0096] like Figure 13 As shown, in some examples, the hand massager 100 may also include a rotary motor 81 and a transfer shaft 82 connected to the power shaft of the rotary motor 81. The transfer shaft 82 is connected to the base 721, and the rotary motor 81 can drive the transfer shaft 82 to rotate, so that the base 721 rotates relative to the housing 10.

[0097] The power shaft of the rotating motor 81 is a screw structure with threads on its outer wall, and the driven gear 83 is sleeved on the outside of the adapter shaft 82. The hand massager 100 also includes a gear transmission assembly, which includes at least two transmission gears 84 of different sizes, and the different transmission gears 84 mesh with each other.

[0098] The power shaft has gear teeth that are adapted to the transmission gear 84. One of the transmission gears 84 in the gear transmission assembly meshes with the gear teeth of the power shaft, and the other transmission gear 84 meshes with the driven gear 83 on the adapter shaft 82.

[0099] In this example, the gear transmission assembly is externally equipped with a gearbox housing 85, which may include an upper housing 851 and a lower housing 852. The gear transmission assembly transmits power through multi-gear meshing, achieving high transmission efficiency and ensuring stable rotation of the seat 721 at a preset speed. Furthermore, this example uses multiple transmission gears 84 of different sizes to form the gear transmission assembly, allowing for flexible adjustment of the rotational speed and output torque of the seat 721 and massage head 722, achieving multi-level speed and torque adjustment to suit personalized massage needs.

[0100] like Figure 4 , Figure 5 as well as Figure 6 As shown, in some embodiments of this application, the hand massager 100 may further include a control circuit board 91.

[0101] The control circuit board 91 can serve as the control unit of the hand massager 100. It can be electrically connected to electrical components such as the drive motor 42, air pump 52, position sensor 48, and rotation motor 81. It can control each electrical component according to the preset program or the user's operation instructions, thereby realizing the regulation of the movement of the sleeve 20, the inflation and deflation operation, and the operation of each massage element, improving the working accuracy of each functional module, and greatly enhancing the user's experience.

[0102] In this embodiment, the control circuit board 91 can adjust the sleeve 20 to perform rolling massage on the fingers, and adjust the back of the hand massager 60, the first palm massager 71 and the second palm massager 72 to perform palm massage, so that the user can select different massage modes according to different massage needs.

[0103] In addition, such as Figure 1 , Figure 7 as well as Figure 11 As shown, in some embodiments of this application, the hand massager 100 may further include a battery 92. The battery 92 is disposed inside the housing 10, and a receiving groove 1222 is provided at the bottom of the front housing bracket 122, in which the battery 92 is disposed. The battery 92 is electrically connected to various electrical components, such as the drive motor 42, air pump 52, position sensor 48, and rotation motor 81, to supply power to these electrical components. The battery 92 may also be electrically connected to a control circuit board 91 to supply power to various electrical components via the control circuit board 91.

[0104] The hand massager 100 may also include a control button 93, which is located on the top of the housing 10. The control button 93 can be electrically connected to the control circuit board 91. When the user presses or twists the control button 93, it can trigger a button operation signal. The control circuit board 91 receives the button operation signal and can execute corresponding instructions such as switching massage modes, adjusting parameters, and starting / stopping.

[0105] In this hand massager, the air chamber of the sleeve can be inflated to expand the sleeve. The expanded sleeve can exert a gentle kneading force on the fingers inside, providing even surface compression to the fingertips, knuckles, and sides of the fingers, effectively promoting blood circulation in the fingers. Furthermore, the squeezing force of the sleeve on the fingers can be flexibly adjusted by the inflation volume to suit the massage intensity needs of different users, ensuring the suitability and safety of the massage. In addition, the ball bearings are located on the inner wall of the sleeve and can rotate relative to it. On one hand, when the air chamber is inflated, it pushes the ball bearings to make close contact with the finger surface. Slight hand movements or the ball bearings rolling naturally with the squeezing force create a dynamic and gentle rolling massage, enhancing the comfort of the massage. On the other hand, the point-contact massage of the ball bearings can precisely target acupoints and meridians on the fingers, stimulating key points and effectively relieving finger muscle tension and hand nerve fatigue.

[0106] The hand massager of this application can achieve a comprehensive massage of the hand fingers by combining sleeve and roller, which is more in line with the physiological structure of the hand and the actual needs of users to relieve fatigue, so as to achieve deep hand relaxation and enhance the overall effect of massage.
