Description

Technical Field

[0001] This utility model belongs to the field of massage equipment technology, and specifically relates to a massage mechanism, particularly one with a floating massage head that can achieve undulating pressure. Background Technology

[0002] Current massage mechanisms mostly use fixed massage heads that generate kneading motions through rotation, but lack dynamic undulating pressure, resulting in monotonous massage intensity and poor adaptability to the human body. Some improvement solutions attempt to add springs to the bottom of the massage head or design the massage head to be able to swing, adapting to the human body surface to avoid a harsh massage technique. For example: CN202210476841.4 discloses a massage device including a linkage seat and a massage head. The linkage seat extends longitudinally upward to form symmetrically positioned double ears. The bottom of the massage head has a block-shaped connecting part, which is located in the center of the double ears and is rotatably connected to the double ears by fasteners. There is a rotational gap between the connecting part and the top surface of the linkage seat. The bottom corner of the connecting part abuts against and limits the movement of the top surface of the linkage seat along the rotation path. An integrally connected rib plate is provided between the connecting part and the bottom of the massage head. Through a subtle design, the massage head has a floating effect, conforming to the human cervical spine. It only provides a self-adaptive oscillation without any change in pressure.

[0003] The object of this invention is to find a more reasonable technical solution. Summary of the Invention

[0004] The purpose of this invention is to design a massage mechanism in which the massage head can also undulate and press during the rotating massage process.

[0005] The present invention is implemented as follows: a massage mechanism includes a gearbox and a massage disc. The gearbox has at least two output shafts, each of which drives the massage disc to rotate. The massage disc is characterized by having fixed massage heads and floating massage heads. The floating massage heads are columnar and pass through a through-hole in the massage disc, with their lower ends in contact with the upper cover of the gearbox. The upper cover has an annular wave pattern centered on the axis of the output shafts. When the floating massage heads move along the annular wave pattern, they generate periodic axial displacement.

[0006] The massage disc is provided with a single fixed massage head and at least one through hole, and each through hole is equipped with an independent floating massage head; the fixed massage head is integrally formed with the massage disc, and the multiple through holes are evenly distributed along the circumference of the massage disc.

[0007] The floating massage head includes a column and a massage head sleeve. The lower end of the column is integrally formed with an abutment ball head, the diameter of which is larger than the minimum diameter of the through hole. The massage head sleeve is fixed to the upper end of the column by a threaded connection or an interference fit, forming a bidirectional constraint structure with the abutment ball head.

[0008] The through hole has a stepped structure, including a narrow sleeve in the upper section and a wide sleeve in the lower section, with a limiting step forming at the junction; the narrow sleeve forms a sliding fit with the column, the wide sleeve allows the ball head to pass through, and the limiting step restricts the upward displacement of the column.

[0009] The wide sleeve is equipped with a compression spring, and the column passes through the spring. The two ends of the spring abut against the limiting step and the abutting ball head, respectively, to form a continuous downward pressure.

[0010] The surface of the top cover is formed with an annular groove, and the annular wave pattern is formed at the bottom of the annular groove, with a height difference of 3-10mm between the crest and trough.

[0011] This invention employs a combination design of a fixed massage head and a floating massage head, and uses a wave-patterned track to drive the floating massage head, superimposing rotational motion with axial undulating motion to achieve a dual massage effect of dynamic kneading and pressing, thus enriching the massage experience.

[0013] Reference Figures 1 to 4 The massage mechanism includes a gearbox 1 and a massage disc 2. The gearbox 1 has at least two output shafts 11. This example uses six output shafts, symmetrically distributed left and right, to achieve a wide range of massage. A single-output-shaft motor or a dual-output-shaft motor can be used, with multi-stage speed-changing gears to achieve a multi-output-shaft design. Each output shaft 11 drives the massage disc 2 to rotate. The output shafts can operate at the same speed or at different speeds, depending on the situation; these are common-sense considerations.

[0014] Reference Figures 1 to 7 The massage turntable 2 is equipped with a fixed massage head 21 and a floating massage head 3, both of which are designed in an eccentric position. The floating massage head 3 has a columnar structure and is inserted into the through hole 22 of the massage turntable 2. Its lower end is in contact with the upper cover 12 of the gearbox. The surface of the upper cover 12 is formed with an annular wave pattern 121 centered on the output shaft axis. When the floating massage head 3 moves along the surface of the annular wave pattern 121, it generates a periodic axial displacement.

[0015] In fact, the surface of the top cover 12 is formed with a circular groove 122 centered on the output shaft 11. A ring-shaped wave pattern 121 is formed at the bottom of the circular groove 122, with a height difference of 3-10mm between the crests and troughs. A larger drop in the wave pattern 121 results in greater undulation and pressure, but also increased resistance. Generally, there are two or more pairs of peaks and troughs, inversely proportional to the height difference. A large number of peaks and troughs ultimately creates a vibrating massage effect.

[0016] More specifically, the massage disc 2 has a single fixed massage head 21 and at least one through hole 22, each through hole 22 being equipped with an independent floating massage head 3. The fixed massage head 21 is integrally formed with the massage disc 2, and the multiple through holes 22 are evenly distributed around the circumference of the massage disc 2. To be precise, excluding the space occupied by the fixed massage head 21, the through holes 22 are evenly distributed around the circumference. Figures 5 to 7 .

[0017] Furthermore, the floating massage head 3 includes a column 31 and a massage head sleeve 32. The lower end of the column 31 is integrally formed with an abutment ball head 311, the diameter of which is larger than the minimum diameter of the through hole 22. The massage head sleeve 32 is fixed to the upper end of the column 31 by a threaded connection or interference fit, forming a bidirectional constraint structure with the abutment ball head 311, preventing it from slipping out of the through hole's constraint. Figure 5 and Figure 7 .

[0018] The through hole 22 has a stepped structure, including an upper narrow sleeve 221 and a lower wide sleeve 222, with a limiting step 223 formed at the junction, such as... Figure 3 and Figure 7The narrow sleeve 221 forms a sliding fit with the column 31, which plays a guiding role; the wide sleeve 222 allows the contact ball head 311 to pass through, satisfying the undulating stroke, and the limiting step 223 restricts the column 31 from continuing to move upward and disengage.

[0019] Furthermore, a compression spring 4 is installed inside the wide sleeve 222, and the column 31 passes through the spring 4. The two ends of the spring 4 abut against the limiting step 223 and the abutting ball head 311 respectively, forming a continuous downward pressure.
