[0034] According to the embodiment of the utility model, a finger pressure massager 100 is provided, please combine Figure 1 、 Figure 3 、 Figure 4 And Figure 5 It is shown that the finger pressure massager 100 includes shell 10, motor 20, base assembly 30 and massage piece 40, shell 10 includes main body part 11 and holding part 12, main body part 11 is cylindrical structure, mainly for accommodating motor 20 and other key components, provide internal space and external protection frame for the whole massager, holding part 12 is also provided as cylindrical structure, the central axis of holding part 12 is arranged at the angle with the central axis of main body part 11, or the central axis of holding part 12 is perpendicular to the central axis of main body part 11, to facilitate user hand operation, the inside of holding part 12 is provided with battery, for power supply to motor 20.Motor 20 is installed in main body part 11, motor 20 includes inner stator and outer rotor, wherein, motor 20 is specifically brushless motor 20, and its structure is the structure form of inner stator and outer rotor.Base assembly 30 is connected with outer rotor, massage piece 40 includes connecting part 41 and massage head 42, connecting part 41 is detachably connected with base assembly 30, to replace massage head 42 according to different needs, massage head 42 is connected with the end of connecting part 41 away from base assembly 30, massage head 42 directly acts on human body for massage, massage head 42 is provided as ellipsoidal structure, the outer surface of massage head 42 is provided with multiple protrusions, improve the human body touch and massage effect in the process of massage.Motor 20, base assembly 30 and massage piece 40 are sequentially arranged along the axial direction of outer rotor, so the layout makes that power transmission is direct, efficient, and the structure is compact, the space utilization between each component is reasonable, and the overall volume is small, convenient to carry and use.

[0035] Wherein, the finger pressure massager 100 further includes mainboard 50 and upper cover 13, mainboard 50 is installed in main body part 11 and located at the side of motor 20 away from base assembly 30, upper cover 13 covers main body part 11, and mainboard 50 is enclosed in the internal space of main body part 11.

[0036] During the operation of the finger pressing massager 100, the base assembly 30 is connected with the outer rotor of the motor 20, and rotates together with the outer rotor of the motor 20, and the massage member 40 is connected with the base assembly 30 through the connecting portion 41, and rotates together with the base assembly 30. The rotation of the outer rotor of the motor 20 in the forward direction or the reverse direction can drive the massage head 42 to reciprocate, so as to simulate the action of finger kneading and pressing, and act on the corresponding part of the human body to achieve the massage effect.

[0037] Compared with the existing simulation human finger massage massager adopting the rudder, cam control principle and software control, the finger pressing massager 100 has a more simple structure, reduces the complex mechanical structure and software control system, and reduces the production and maintenance costs. The detachable massage head 42 can be replaced at any time according to the needs of the user, and meets the needs of different parts and different massage forces. Moreover, the overall structure is compact and convenient to carry, and can be used at any time at home, in the office or on a trip. The reciprocating rotation of the massage head 42 driven by the motor 20 can more realistically simulate the action of finger kneading and pressing, and provide effective massage experience for the user, and relieve body fatigue and muscle soreness.

[0038] In some embodiments, the base assembly includes a base module and an adaptive module, the base module is connected with the rotor of the motor 20, and plays a role of receiving the power of the motor 20 and transmitting it to the adaptive module, the adaptive module is connected with the base module and the massage member 40 respectively, and the adaptive module includes elastic elements (such as springs) or slidable structures, so as to realize the movement of the massage member 40 along the axial direction under the condition of bearing the axial direction pressure or tension. The adaptive module can flexibly adjust the position of the massage member 40 according to the external force. The movement distance is positively correlated with the size of the pressure or tension.

[0039] Understandably, when the massage head 42 contacts the human body massage part, the pressure or tension of the human body is received, and the adaptive module bears the axial direction pressure or tension transmitted from the massage head 42. At this time, the elastic elements or slidable structures in the adaptive module will deform or displace according to the size of the pressure or tension, so as to drive the massage member 40 to move along the axial direction. For example, when the pressure increases, the elastic elements are compressed, and the massage member 40 moves towards the motor 20; when the pressure decreases, the elastic elements recover, and the massage member 40 moves away from the motor 20. At the same time, the rotor of the motor 20 rotates in the forward direction or the reverse direction, drives the massage head 42 to reciprocate, and combines the axial movement of the massage member 40 to realize a more flexible and human body fitting massage action.

[0040] It should be noted that the adaptive module can realize the adaptive function when bearing the pressure or tension by containing at least one of the following structures:

[0041] First, spring structure, install compression spring between base module and massage piece 40 connecting part. When massage head 42 contact human body is under pressure, compression spring is compressed, massage piece 40 moves to the direction of close to motor 20, pressure disappears, spring rebounds and makes massage piece 40 reset;

[0042] Second, block elastomer (not shown in the figure), adopt the rubber or silicone elastomer with elastic and make block structure, place between base module and massage piece 40. The elasticity of block elastomer can be adjusted according to the formula and thickness of material. Block elastomer needs to have good flexibility, can provide certain buffer and self-adaptive ability in all directions, and can effectively reduce vibration transmission. In some massage machines with higher requirements for massage comfort, block elastic rubber or silicone can be used as self-adaptive module, so that the massage process is more soft and avoids the hard massage touch;

[0043] Third, pneumatic cylinder (not shown in the figure), use compressed air as power medium, one end of cylinder is fixed with base module, the other end is connected with massage piece 40 through piston rod. When massage head 42 is under pressure or tension, piston rod moves in cylinder, compresses or releases air in cylinder. By adjusting the air pressure in cylinder, the moving resistance and sensitivity of massage piece 40 can be controlled.

[0044] In some embodiments, the self-adaptive module can also be a combination structure of sliding guide rail and elastic element, install guide rail on base module, the connecting part of massage piece 40 is matched with guide rail through sliding block, which can slide along the guide rail. At the same time, spring is arranged between guide rail and sliding block or between base module and massage piece 40. When massage head 42 is under stress, sliding block slides on guide rail, spring deforms, so as to realize the self-adaptive movement of massage piece 40. The above structure combines the guiding effect of guide rail and the elastic buffer of spring, which can ensure the accuracy of the axial movement of massage piece 40, and provide appropriate buffer force at the same time, which is suitable for massage machines with high requirements for the movement precision and stability of massage piece 40. In some exemplary embodiments, please combine Figure 1 、 Figure 3 and Figure 5As shown, the base assembly 30 includes a fixed plate 31, a mounting seat 32 and an elastic connection assembly 33. The fixed plate 31 is in a circular plate structure, and is provided with a plurality of first through holes 311. The mounting seat 32 is provided with a plurality of second through holes 322. The side of the fixed plate 31 facing the mounting seat 32 is provided with a boss 312 for positioning. The mounting seat 32 is located on the side of the fixed plate 31 away from the motor 20. The end of the mounting seat 32 facing the fixed plate 31 is provided with a positioning groove 323 matched with the boss 312. The boss 312 is inserted into the positioning groove 323. The fixed plate 31 and the mounting seat 32 are positioned and connected through the boss 312 and the positioning groove 323. Then a plurality of bolts 60 are sequentially inserted through the second through holes 322 of the mounting seat 32 and the first through holes 311 of the fixed plate 31 and connected to the outer rotor. The fixed plate 31 and the mounting seat 32 are fixedly installed on the outer rotor of the motor 20 together, ensuring the stable connection of the base assembly 30 and the outer rotor of the motor 20 and ensuring the effective transmission of power.

[0045] The end of the mounting seat 32 away from the fixed plate 31 is provided with an assembly groove 321. The elastic connection assembly 33 is installed in the assembly groove 321, for example, the elastic connection assembly 33 is fixed in the assembly groove 321 by interference fit, clamping or the like, to prevent the elastic connection assembly 33 from falling out of the assembly groove 321 during work. The end of the elastic connection assembly 33 away from the fixed plate 31 is connected with the massage head 42. The connection between the elastic connection assembly 33 and the massage head 42 can be threaded connection, buckle connection or the like, to realize the connection between the massage head 42 and the base assembly 30. The elastic connection assembly 33 can be elastically deformed along the axial direction of the outer rotor. During the rotation of the massage head 42, the elastic connection assembly 33 can be elastically deformed along the axial direction of the outer rotor. When the massage head 42 contacts the human body massage part, the elastic connection assembly 33 will be elastically deformed according to the stress condition, so that the massage head 42 can better fit the surface of the human body, and provide cushioning during the massage process, avoiding excessive massage force causing discomfort to the human body.

[0046] Further, please refer to Figure 1 , Figure 3 and Figure 5As shown, the elastic connecting assembly 33 comprises a support base 331, a spring base 332, an elastic member 333 and a support rod 334. The support base 331 is installed in the assembly groove 321 of the mounting base 32 and serves to fix and support the entire elastic connecting assembly 33. The support base 331 is provided with a sliding hole 3311 extending through the outer rotor in the axial direction, which provides space and guidance for the installation and movement of the spring base 332, the elastic member 333 and the support rod 334. The support base 331 can be made of plastic or metal with high strength to ensure its stability during the operation of the massager. The spring base 332 is installed in the sliding hole 3311 and located at one end of the sliding hole 3311 facing the fixed plate 31. The spring base 332 is mainly used for fixing one end of the elastic member 333 to ensure the stability of the position of the elastic member 333 during operation. The spring base 332 is adapted in shape and size to the sliding hole 3311, and the connection between the spring base 332 and the sliding hole 3311 can be achieved by interference fit or clamping. The elastic member 333 is arranged in the sliding hole 3311, one end of the elastic member 333 is connected to the spring base 332, and the other end of the elastic member 333 is connected to the support rod 334. The elastic member 333 is specifically a spring, which can be elastically deformed during the massage process to provide a buffering force. One end of the support rod 334 is slidably arranged in the sliding hole 3311 and connected to the other end of the elastic member 333, and the other end of the support rod 334 is located outside the sliding hole 3311 and connected to the connecting part 41. The support rod 334 serves to connect the elastic member 333 and the connecting part 41, and transmits the elastic force of the elastic member 333 to the connecting part 41, which in turn acts on the massage head 42. In this embodiment, the support rod 334 is a metal rod with high strength to ensure that it will not bend or deform during force transmission.

[0047] During the operation of the finger press massager 100, the motor 20 drives the outer rotor to rotate, drives the base assembly 30 to rotate, and in turn drives the elastic connecting assembly 33 connected to the base assembly 30 to rotate. When the massage head 42 contacts the human body massage part, the massage head 42 will produce an axial displacement relative to the base assembly 30 due to the resistance of the human body. At this time, the support rod 334 slides in the sliding hole 3311, compresses the elastic member 333 (spring), the spring is elastically deformed, generates a reverse elastic force, so that the massage head 42 can better fit the surface of the human body, and provides a buffer during the massage process to avoid excessive massage force causing discomfort to the human body. When the massage head 42 leaves the surface of the human body, the spring returns to its original state, and the support rod 334 returns to the initial position under the action of the elastic force of the spring.

[0048] In this embodiment, the elastic member 333 can effectively buffer the impact force generated when the massage head 42 contacts the human body, avoiding excessive massage force from causing harm to the human body, making the massage process more comfortable and safe. Through the elastic deformation of the elastic connecting assembly 33, the massage head 42 can better fit different parts and curves of the human body, improving the effect and coverage of the massage. Whether it is a flat back or an irregular neck, the massage head 42 can closely fit, achieving all-around massage.

[0049] Further, please refer to Figure 1 , Figure 3 and Figure 5 , one end of the support rod 334 towards the spring base 332 is provided with a guide hole 3341, and the elastic connecting assembly 33 further includes a guide shaft 335, which is arranged in the sliding hole 3311, and one end of the guide shaft 335 is connected with the spring base 332, and the other end of the guide shaft 335 is slidably inserted into the guide hole 3341. The shape of the guide hole 3341 is matched with the guide shaft 335, and the guide hole 3341 is set as a circular hole for providing accurate guidance for the guide shaft 335. The guide shaft 335 cooperates with the support rod 334 in the sliding hole 3311 along the axial direction of the outer rotor, and the guide shaft 335 and the guide hole 3341 of the support rod 334 form a guide structure, further ensuring the consistency and stability of the movement of the internal components of the elastic connecting assembly 33.

[0050] When the massage head 42 contacts the human body massage part and generates axial displacement, the support rod 334 slides in the sliding hole 3311, compressing the elastic member 333 (spring). At this time, the guide shaft 335 moves with the position change of the spring base 332, and since the guide shaft 335 is slidably inserted into the guide hole 3341, it can guide the support rod 334 to move along the accurate axial direction, avoiding the support rod 334 from deviating or shaking during sliding. When the massage head 42 leaves the human body surface, the spring returns to its original state, and the support rod 334 returns to the initial position along the guide direction of the guide shaft 335 under the action of the spring force. The guide shaft 335 always provides stable guidance for the movement of the support rod 334 during the whole process, ensuring the normal work of the elastic connecting assembly 33 and the stability of the massage effect.

[0051] In this embodiment, the cooperation of the guide shaft 335 and the guide hole 3341 can accurately guide the movement direction of the support rod 334, making the axial movement of the massage head 42 in the working process more stable and accurate, avoiding uneven massage force caused by the shaking or deviation of the support rod 334, and improving the quality and effect of the massage. Moreover, it also effectively enhances the overall stability of the elastic connecting assembly 33, making the work of the elastic connecting assembly 33 more reliable and reducing the probability of failure caused by unstable movement.

[0052] Further, as shown in Figure 1 , Figure 3 and Figure 5 , the circumferential outer surface of the spring base 332 is provided with external threads, and the inner wall of the sliding hole 3311 is provided with internal threads matched with the external threads. The spring base 332 is tightly combined with the sliding hole 3311 through threaded connection. During installation, the external threads of the spring base 332 are aligned with the internal threads of the sliding hole 3311, and then the spring base 332 is gradually screwed into the sliding hole 3311 by rotating the spring base 332. The spring base 332 and the support seat 331 have high connection strength and stability through threaded connection, and can withstand various forces generated during the operation of the massager, including the elastic force of the spring, the pulling force of the support rod 334, and the impact force generated when the massage head 42 contacts the human body, etc., ensuring that the spring base 332 will not easily loosen or fall off in the sliding hole 3311.

[0053] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 5 , the inner wall of the assembly groove 321 is provided with a protruding structure 3211, and the circumferential outer surface of the support seat 331 is provided with a groove structure 3312. The protruding structure 3211 and the groove structure 3312 are connected by clamping. The protruding structure 3211 can be a continuous annular protruding strip, or a plurality of uniformly distributed protruding blocks. The protruding structure 3211 and the groove structure 3312 correspond to each other on the contact surface of the two. When the support seat 331 is placed into the assembly groove 321, the protruding structure 3211 is embedded in the groove structure 3312, forming a tight fitting relationship along the circumferential direction of the support seat 331 and the inner wall direction of the assembly groove 321, ensuring the stability of the position of the support seat 331 in the assembly groove 321, and preventing relative rotation or axial displacement.

[0054] In other embodiments, the circumferential outer surface of the support seat 331 is provided with a protruding structure 3211, and the inner wall of the assembly groove 321 is provided with a groove structure 3312. The protruding structure 3211 and the groove structure 3312 are connected by clamping. When the support seat 331 is placed into the assembly groove 321, the protruding structure 3211 is embedded in the groove structure 3312, forming a tight fitting relationship along the circumferential direction of the support seat 331 and the inner wall direction of the assembly groove 321, ensuring the stability of the position of the support seat 331 in the assembly groove 321, and preventing relative rotation or axial displacement.

[0055] Understandably, the support seat 331 is installed in the assembly groove 321 by clamping connection, which only needs to be aligned with the assembly groove 321 and pushed in for simple installation, greatly improving the production and assembly efficiency and reducing the assembly cost.

[0056] Further, as shown in Figure 1 ,Figure 2 、 Figure 3 and Figure 5 As shown in Figure 1 、 Figure 3 and Figure 5 , the inner wall of the sliding hole 3311 is provided with a sliding groove 33111 extending along the axial direction of the outer rotor, and the circumferential outer surface of the support rod 334 is provided with a convex rib 3342 extending along the axial direction of the outer rotor, which is slidably arranged in the sliding groove 33111. The convex rib 3342 is located on the outer surface of the support rod 334, and the sliding groove 33111 is located on the inner wall of the sliding hole 3311, and they correspond to each other in the radial direction. When the support rod 334 is installed in the sliding hole 3311, the convex rib 3342 is embedded in the sliding groove 33111, and along the axial direction of the outer rotor, the convex rib 3342 and the sliding groove 33111 form an accurate guide and constraint structure, which ensures that the support rod 334 can only move linearly in the axial direction, and cannot rotate circumferentially or deviate radially.

[0057] The cooperation of the sliding groove 33111 and the convex rib 3342 provides accurate guidance for the support rod 334, making the movement of the support rod 334 in the sliding hole 3311 more stable and accurate, ensuring that the axial displacement of the massage head 42 during the working process can be accurately controlled, and improving the quality and effect of the massage. Whether it is the uniformity of the massage force or the accuracy of the massage position, it can be effectively guaranteed. And effectively limit the freedom of movement of the support rod 334, avoid the shaking or deviation of the massage head 42 caused by the unstable movement of the support rod 334, and enhance the stability of the entire elastic connection assembly 33 and the massager.

[0058] Further, as shown in Figure 1 、 Figure 3 and Figure 5 , the connecting part 41 includes a connecting seat 411 and a connecting rod 412, the connecting seat 411 is provided with a through hole 4111 and a connecting hole 4112, the through hole 4111 penetrates the connecting seat 411 along the axial direction of the outer rotor, the connecting hole 4112 is arranged at an angle with the axial direction of the outer rotor, and the connecting hole 4112 is communicated with the through hole 4111, the end of the support rod 334 away from the motor 20 is inserted into the through hole 4111 and provided with a threaded hole, and the connecting seat 411 and the support rod 334 are fixedly connected by the bolt 60 passing through the connecting hole 4112 and being inserted into the threaded hole, so that the connecting seat 411 is detachably connected to the base assembly 30, one end of the connecting rod 412 is connected to the connecting seat 411, and the other end of the connecting rod 412 is connected to the massage head 42.

[0059] The connecting rod 412 is arranged in an arc-shaped bent rod structure, and is an elastic member 333, and can play a buffering role when the massage head 42 contacts the human body. When the massage head 42 is subjected to the reaction force of the human body, the connecting rod 412 will be elastically deformed, thereby avoiding that the instantaneous excessive impact force directly acts on the human body, effectively reducing the discomfort possibly brought to the user due to the excessively large massage force, and making the massage process more soft and comfortable, and being especially suitable for the user who is more sensitive to the massage force.

[0060] Further, the outer rotor has a rotation axis, and an extension line of the rotation axis passes through the massage head 42. In the embodiment, the motor 20 is installed in the main body part 11, the motor 20, the base assembly 30 and the massage part 40 are sequentially arranged along the axial direction of the outer rotor, and the extension line of the rotation axis of the outer rotor passes through the massage head 42. The above arrangement makes the power transmission direct and efficient, and the structure is compact, the space between the components is reasonably utilized, and the whole is small in size and convenient to carry and use.

[0061] It should be further pointed out that the extension line of the rotation axis of the outer rotor passes through the massage head 42, so that the power transmission is more uniform and stable. When the massage head 42 rotates, the driving force in each direction is consistent, so that the situation that the massage force is large or small due to uneven force is avoided, the massage process is more stable and comfortable, and the massage effect is improved.
