Abstract
Description
Technical Field
[0001] This utility model relates to an abdominal massager, and more particularly to a compact single-disc abdominal massager. Background Technology
[0002] Chinese utility patent CN218792990U discloses a novel abdominal massager. The motor drives the transmission rod to rotate through the worm shaft, which in turn drives the main gear to rotate. The main gear is connected to a turntable through a polygonal pin, and a massage head is set on the turntable. The turntable is driven by the polygonal pin, which has a short lever arm and high rotational resistance. Utility Model Content
[0003] In view of the technical problems existing in the background art, the present invention aims to provide a compact single-disc abdominal massager, in which the turntable meshes with the transmission component through an internal gear ring, and is provided with an annular groove to cooperate with the ball to reduce the coefficient of friction, with a long lever arm and low rotational resistance.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This compact single-disc abdominal massager includes a shell, wherein a motor, a transmission component, a turntable, and a support are provided inside the shell. The motor is located in the middle of the shell and has an output shaft, which is a worm gear. The transmission component is rotatably arranged and includes a first gear and a second gear, which are coaxially arranged. The first gear meshes with the output shaft, and the teeth of the first gear are inclined. The rotation center line of the transmission component is perpendicular to the rotation center line of the output shaft. The turntable has an internal gear ring and an annular groove. The internal gear ring meshes with the second gear, and the diameter of the internal gear ring is larger than the diameter of the annular groove. The support has a groove along the circumference for placing ball bearings, and the ball bearings cooperate with the annular groove.
[0005] In this design, the annular groove moves along the circumferentially arranged balls on the support, resulting in a low coefficient of friction and functioning similarly to a bearing. This design is cost-effective. The transmission component meshes with the internal gear ring of the turntable via a second gear, is far from the rotation center, has a long lever arm, saves effort, and has fewer transmission stages. The support provides support for the turntable, and the rotation center line of the motor output shaft is perpendicular to the rotation center line of the transmission component. The design is compact and thin overall.
[0006] Preferably, the motor is electrically connected to a power interface.
[0007] This design eliminates the need for a battery inside the casing, resulting in a more compact overall structure.
[0008] Preferably, it also includes an inner shell, in which the motor and the transmission component are disposed, the inner shell has an opening for the second gear to be exposed, the inner shell is connected to the bracket, and the inner shell has heat dissipation holes.
[0009] In this design, the inner shell forms a relatively sealed space to further protect the motor and transmission components, thereby increasing their service life.
[0010] Preferably, the turntable is sleeved on the bracket, and the turntable is equipped with a limiting pressure plate, which is inserted into the bracket.
[0011] In this design, the turntable is mounted on the bracket, and the annular groove provides circumferential restriction for the turntable. The limiting pressure plate ensures that the inverted turntable will not separate from the bracket.
[0012] Preferably, a fixed plate is installed on the turntable, the fixed plate is provided with massage heads along the circumference, and an essential oil reservoir is provided at the center of the fixed plate.
[0013] In this design, the essential oil reservoir diffuses essential oils to enhance the massage effect.
[0014] The beneficial effects of this utility model are that it designs an internal gear ring to increase the lever arm, and designs an annular groove and ball bearings to achieve the effect of a bearing, resulting in fewer transmission stages and a compact overall structure. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description

The rotation center line of the transmission component 2 is perpendicular to the rotation center line of the output shaft. The turntable 5 has an internal gear ring 6 and an annular groove 7. The internal gear ring 6 meshes with the second gear 4, and the internal gear ring 6 has a large diameter. The bracket 14 has a groove 8 around the diameter of the annular groove 7 for placing ball bearings. The ball bearings cooperate with the annular groove 7. The bracket also includes an inner shell 9. The motor and the transmission component 2 are disposed inside the inner shell 9. The inner shell 9 has an opening for the second gear 4 to be exposed.
