Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically a massage head assembly. Background Technology

[0002] Massage devices (such as massage chairs, massage guns, and handheld massagers) relieve fatigue and soreness by physically stimulating the human body. Their core components are the power unit and the massage head assembly that directly contacts the body. As a key component for achieving different massage experiences, the shape design of the massage head directly affects its adaptability and effectiveness for different body parts (such as deep trapezius muscles or large areas of back / leg muscles).

[0003] However, traditional massage devices generally use fixed massage heads, whose single shape (such as oval or spherical heads) cannot flexibly adapt to diverse massage needs: users need sharp massage heads to concentrate pressure when massaging deep muscles (such as the trapezius muscle), while massaging large areas of muscles requires gentle massage heads to avoid overstimulation. The single function forces users to frequently change massage head accessories of different shapes, which not only increases the burden of carrying and the cost of use, but also seriously affects the convenience of use. Therefore, we propose a new type of massage head component. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a massage head assembly that can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A massage head assembly, comprising:

[0007] Top rod, serving as a support component;

[0008] The pressure block is cylindrical in shape, and its top center is connected to the top of the top rod by a connecting screw rod.

[0009] At least one locking block is fixed to the top of the outer circular surface of the pressure block;

[0010] Two massage head shells are slidably sleeved on the outside of the pressure block, and their inner cavities are provided with slots that are adapted to the locking block;

[0011] Two symmetrical rotating channels are formed in the inner cavity of the massage head shell, and are arc-shaped and coincide with the axis of the pressure block;

[0012] A spring cavity is located below the pressure block;

[0013] Several telescopic springs are disposed within the spring cavity;

[0014] A decorative cover is fixed to the outer arc surface of the inner shell of the massage head.

[0015] Preferably, the top end of the top rod and the center of the top of the pressure block are both provided with threaded holes that are compatible with the connecting screw rod.

[0016] Preferably, the two massage head shells are joined together to form a complete elliptical head-shaped shell by a locking screw, the locking screw being located inside the massage head shell, and the spring cavity being opened at the bottom of the massage head shell.

[0017] Preferably, the slots in the inner cavity of the massage head are arranged in a ring array, and the included angle between adjacent slots is ninety degrees.

[0018] Preferably, the rotating channel is an arc-shaped strip that coincides with the axis of the pressure block, and the slot is located at the end of the rotating channel.

[0019] Preferably, the curvature of the decorative cover is consistent with the curvature of the outer arc surface of the inner shell of the massage head.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By setting up a mechanical linkage structure of locking blocks, locking slots and rotating channels, and utilizing the sliding guidance of the locking blocks in the rotating channels and the 90-degree positioning function of the locking slots, the massage head shell can efficiently switch between two working modes: the end of the major axis of the ellipse and the end of the minor axis. This allows for concentrated pressure to be applied to deep muscle groups, as well as the relaxation of large muscle areas with a wide contact surface, thus solving the technical problems of traditional fixed massage heads having limited functions and applicable scenarios.

[0022] 2. By setting up an elastic reset mechanism for the telescopic spring and the pressure block, combined with the three-step operation logic of pressing, rotating and releasing with one hand, the mode switching process is simplified into an instant operation without the need for tools. Users can quickly switch between the two modes with just one hand, which greatly reduces the operational complexity and usage cost caused by frequent replacement of parts in traditional massage devices, and significantly improves the ease of use.

[0030] This utility model provides a technical solution:

[0031] Please see Figures 1-4 A massage head assembly includes: a top rod 1, serving as a support component; a pressure block 2, cylindrical in shape, with its top center connected to the top of the top rod 1 via a connecting screw; at least one locking block 3, fixed to the top of the outer circular surface of the pressure block 2; two massage head shells 4, slidably sleeved on the outside of the pressure block 2, with their inner cavities having locking grooves 5 adapted to the locking blocks 3; two symmetrically formed rotating channel grooves 6, arc-shaped and coinciding with the axis of the pressure block 2, located within the inner cavities of the massage head shells 4; a spring cavity 7, located below the pressure block 2; several telescopic springs 8, disposed within the inner cavities of the spring cavities 7; and a decorative cover 9, fixed to the outer arc surface of the massage head shells 4.

[0032] During operation, the top rod 1 acts as the core support, transmitting power. The pressure block 2 is rigidly connected to the top rod 1 via a connecting screw, forming a central axis. The locking block 3 on the outer surface of the pressure block 2 is embedded in the locking groove 5 within the inner cavity of the massage head shell 4 to achieve angle positioning. The massage head shell 4 is slidably fitted onto the outside of the pressure block 2, and the locking block 3 is guided to slide along an arc-shaped path through the rotating channel 6 within the inner cavity, driving the massage head shell 4 to rotate. The telescopic spring 8 is located within the spring cavity 7, providing downward resistance and automatic reset elasticity, allowing the locking block 3 to precisely engage with the adjacent 90° new locking groove 5 after disengaging from the old one, thus completing the shape locking. The decorative cover 9 covers the seam of the massage head shell 4 and optimizes the curvature of the appearance. All components work together to achieve a rapid shape switching function of single-handed pressing-rotating-releasing.

[0033] In some embodiments, the top end of the push rod 1 and the center of the top of the pressure block 2 are both provided with threaded holes adapted to the connecting screw rod.

[0034] In this embodiment, the push rod 1 and the pressure block 2 are rigidly connected by a connecting screw rod passing through the threaded hole of both, forming a stable central axis. This threaded hole structure ensures that there is no relative displacement or rotation between the push rod 1 and the pressure block 2 during power transmission, so that the locking block 3 on the outer wall of the pressure block 2 always maintains a precise angular positioning, providing a reliable support reference for the rotation switching of the massage head shell 4.

[0035] In some embodiments, the two massage head shells 4 are spliced ​​together to form a complete elliptical head-shaped shell by locking screws. The locking screws are located inside the massage head shells 4, and the spring cavity 7 is opened at the bottom of the massage head shells 4.

[0036] In this embodiment, the locking screw tightly splices the two massage head shells 4 from the inside into a complete elliptical head-shaped shell, ensuring that the massage surface is seamless and smooth, avoiding skin pinching. This maintains the continuous curvature of the outer arc surface of the massage head to optimize the massage experience, and also ensures the overall structural rigidity of the shell during rotation switching and stress. In addition, the spring cavity 7 is opened at the bottom of the massage head shell 4 to facilitate the subsequent installation of the telescopic spring 8.

[0037] In some embodiments, the slots 5 inside the inner cavity of the massage head shell 4 are arranged in a ring array, and the included angle between adjacent slots 5 is ninety degrees.

[0038] In this embodiment, the ring-shaped array of slots 5 divides the semicircle into 90° segments, ensuring that the locking block 3 can precisely engage with the adjacent slot 5 each time the massage head shell 4 rotates, forcibly limiting the rotation angle to a fixed 90°. This design ensures both rapid positioning and stable locking of the working mode at the major / minor axis of the ellipse, and avoids switching failures caused by user rotation angle deviations, supporting the reliability of single-handed operation and the efficiency of mode switching.

[0039] In some embodiments, the rotating channel 6 is an arc-shaped strip that coincides with the axis of the pressure block 2, and the slot 5 is located at the end of the rotating channel 6.

[0040] In this embodiment, the arc-shaped path of the rotating channel 6 coincides with the axis of the pressure block 2, guiding the locking block 3 to slide along the set trajectory; the locking slot 5 is located at the end of the channel, so that the locking block 3 falls into the locking slot 5 precisely when it rotates to the correct position, achieving mechanical self-locking. This structure not only ensures the smoothness of rotation switching, but also ensures accurate positioning of the 90° rotation angle through the limiting at the end of the channel, avoiding misalignment or false locking.

[0041] In some embodiments, the curvature of the decorative cover 9 is consistent with the curvature of the outer arc surface of the inner shell 4 of the massage head.

[0042] In this embodiment, the decorative cover 9 and the outer arc surface of the massage head shell 4 have the same curvature, so that the two are spliced ​​together to form a continuous and smooth massage surface, eliminating the seam protrusion. This design ensures that the pressure is evenly transmitted to the human body during massage, avoiding excessive local pressure and causing discomfort, while maintaining the integrity of the oval head shape to adapt to different body parts, improving the comfort of use and the massage effect.

[0043] In practical use, the working principle of this utility model is as follows:

[0044] When a user needs to adjust the massage mode to suit different body parts, such as switching from stimulating the deep trapezius muscles to soothing large areas of back muscles, it can be done with just one hand: press down directly on the massage head housing 4, overcoming the resistance of the telescopic spring 8, causing the massage head housing 4 to slide downwards relative to the pressure block 2. This action forces the locking block 3 out of the current slot 5, while the telescopic spring 8 is compressed and stores energy. Maintaining the downward pressure, rotate the massage head housing 4 counterclockwise by 90 degrees. At this time, the locking block 3 moves along the guide path of the rotating channel 6. After rotating to the correct position, release the massage head housing 4, and the compressed telescopic spring 8 immediately releases energy and rebounds upwards, pushing the massage head housing 4 back to its original position. During this process, the locking block 3 is precisely guided by the rotating channel 6 and finally firmly locks into the new slot 5 at an adjacent 90-degree angle, achieving reliable mechanical locking, and the mode conversion is completed. Through this structural design, the massage head assembly can efficiently switch between two working modes: when the massage head shell 4 operates at its elliptical major axis end, the contact surface is small and the pressure is concentrated, effectively penetrating and acting on deep muscle groups such as the trapezius muscle; while when it switches to operating at its elliptical minor axis end, it forms a wide and gentle massage surface, which can evenly distribute the pressure, making it particularly suitable for relaxing and soothing large muscle groups such as the back and legs. The entire switching process requires no tools or additional accessories; the user only needs to complete three consecutive actions of pressing, rotating, and releasing with one hand to instantly achieve the mode conversion. This fundamentally solves the significant technical defects of traditional fixed massage heads, such as the single shape and limited function, which lead to the inconvenience and increased cost caused by users having to carry and replace multiple accessories.

[0045] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
