[0007] The technical solutions of the embodiments of the present invention will be described clearly and completely below with reference to the drawings of the embodiments. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments that can be obtained by those skilled in the art without creative ingenuity fall within the scope of protection of the present invention.

[0008] The technical means of the present invention will be described with reference to Figures 1 to 4. The massager of the present invention comprises an outer shell 1, a driving unit 2, a transmission assembly 3, and a plurality of movable members 4. The driving unit 2 and transmission assembly 3 are mounted on the outer shell 1, and the driving unit 2 is connected to the transmission assembly 3 to operate the transmission assembly 3 in a predetermined manner. Each movable member 4 is connected to the transmission assembly 3 and performs a cross-reciprocating motion while its posture is constrained by the outer shell 1 through power transmission. This cross-reciprocating motion may be in the form of multiple movable members 4 alternately moving forward and backward in the same direction. The number of movable members 4 can be set to 2 to 5, etc., depending on the application. The drive unit 2 comprises an electric motor, which drives a transmission assembly 3 to convert its rotational motion into a cross reciprocating motion of a movable member 4, which acts on the massage area. The outer shell 1 has a gripping portion, and the gripping area is covered with soft rubber so that it fits comfortably against the palm of the hand during use. A space for accommodating the drive unit 2 is formed inside the outer shell 1. The transmission assembly 3 includes a rotating shaft 31 and balls 32. The driving unit 2 is connected to the rotating shaft 31 and drives the rotating shaft 31 to rotate. A spiral groove 5 is formed in the rotating shaft 31, and each movable member 4 is connected to the spiral groove 5 via a ball 32. The balls 32 are capable of rolling within the spiral groove 5. A limiting groove 6 is formed between the outer shell 1 and the rotating shaft 31 and extends along the central axis of the rotating shaft 31. A portion of the movable member 4 is positioned within the limiting groove 6 and undergoes cross-axial reciprocating motion in the central axis direction as the rotating shaft 31 rotates. The driving unit 2 rotates the rotating shaft 31 around its central axis, and a portion of the movable member 4 is held within the limiting groove 6, preventing the movable member 4 from rotating. Due to the action of the spiral groove 5 and the limiting groove 6, the movable member 4 undergoes cross-axial reciprocating motion in the central axis direction. The movable member 4 has a rolling chamber 7 in which a part of the ball 32 can fit. The ball 32 can rotate freely within the rolling chamber 7, reducing friction with the movable member 4. The rolling chamber 7 can accommodate more than half of the balls 32, ensuring reliable connection between the balls 32 and the movable member 4 and preventing them from falling off. The spiral groove 5 has a height difference along the central axis direction, and this height difference forms the stroke of the movable member 4. With this configuration, the movable member 4 can perform a cross reciprocating motion along the central axis direction of the rotation shaft 31. Furthermore, the spiral groove 5 has a continuous closed loop from the start end to the end end, allowing the movable member 4 to reciprocate continuously. The limiting grooves 6 can be configured to be provided at equal intervals around the circumference of the rotating shaft 31, and it is preferable that a corresponding movable member 4 is disposed in each limiting groove 6. This allows each movable member 4 to move stably within the corresponding limiting groove 6. Separating ribs 8 are provided on the inner surface of the outer shell 1, and the limiting grooves 6 are located between the separating ribs 8. This allows the movable member 4 to always move stably between the limiting grooves 6 during movement, preventing displacement. The outer surface of the movable member 4 has a wavy shape, with the height differences between the peaks and valleys set in multiple patterns. This increases the contact area and improves the massage effect. The movable members with different peak and valley patterns can provide massages of various intensities, making it suitable for a wide range of users. The outer periphery of each movable member 4 is covered with a flexible coating made of medical-grade silicone, which is biocompatible, flexible, and durable, improving safety and comfort.

[0009] In use, the rotational motion of the drive unit 2 rotates the rotating shaft 31 of the transmission assembly 3. This causes the balls 32 to rotate circulatingly along the trajectory of the spiral groove 5, and as the balls 32 rotate freely within the rolling chamber 7, the movable member 4 moves along the trajectory of the spiral groove 5. Because the movable member 4 is positioned within the restricting groove 6, it can perform a cross-reciprocating motion along the central axis of the rotating shaft 31. Furthermore, the wavy outer surface of the movable member 4 allows for a wide and deep massage, overcoming the limitations of a single massage method. The alternating massage provides smooth changes in force, providing multi-layered stimulation and significantly improving comfort.
