Description

Technical Field

[0001] This utility model relates to the field of massager technology, and more specifically, to a neck massager. Background Art

[0002] The cervical spine is the main support of the human body and is closely connected to the medulla oblongata, the life center of the body. It has rich blood vessels and nerve plexuses, ensuring the transmission of information and the delivery of nutrients for basic life activities. Any slight change can lead to discomfort in the body's organs. With the acceleration of the pace of life, the incidence and younger age of onset of cervical spondylosis are increasing year by year, seriously affecting people's lives and work. Nowadays, people generally use neck massagers to relieve cervical fatigue.

[0003] Existing neck massagers with kneading and tapping functions include a lower cover and an upper cover mounted on top of the lower cover. A motor is mounted on the top surface of the lower cover. A straight toothed shaft is mounted on the top surface of the lower cover on one side of the motor, and a double-toothed shaft is mounted on the top surface of the lower cover on the other side of the straight toothed shaft. A guide groove is provided on the top surface of the upper cover. This design uses a motor to provide driving force, which, guided by the guide groove, drives the ball-head massage mechanisms on both sides to rotate in a coordinated manner, acting on the neck and creating a kneading function. The output direction of the motor is controlled by a circuit board. The tapping massage mechanism does not operate during the forward rotation of the motor; after the motor rotates in the reverse direction, it drives the tapping shaft to perform up-and-down tapping movements. Under the control of the circuit, it can achieve arbitrary forward and reverse rotation, high and low speed combinations, and other functions.

[0004] However, how to improve the design of the massager mechanism to make the internal structure more compact, the transmission smoother, and the transmission structure more supportive has become the direction of our thinking on improving the existing technology. Summary of the Invention

[0032] By adopting the above technical solution, in this utility model, when the drive motor 25 rotates forward, the massage head mechanism 3 operates and performs a kneading action; when the drive motor 25 rotates in reverse, the second massage arm 35 drives the third massage head 36 to perform a tapping action. Alternatively, the one-way bearing 221 can be omitted, and the drive motor 25 can rotate to simultaneously perform both kneading and tapping actions on the massage head mechanism 3. Specifically, the tapping action is achieved by the drive motor 25 driving the drive wheel 72 to rotate, and the drive wheel 72, through the transmission belt 73, drives the driven wheel 71 and the eccentric shaft 222 to move, thereby driving the second massage arm 35 and the third massage head 36 to perform the tapping action through the tapping drive mechanism 4. The specific operation of the first transmission mechanism 6 is as follows: the drive motor 25 drives the worm gear 61 to rotate, and then the worm gear 62, the first transmission gear 63, the second transmission gear 64, the third transmission gear 65, the fourth transmission gear 66, the first bevel gear 67 and the second bevel gear 68 drive the first rotating shaft 21 to rotate, thereby causing the swing drive member 5 to rotate, so that the first massage head 33, the second massage head 34 and the third massage head 36 can perform kneading action. Specifically, this causes the first massage arm 32 and the second massage arm 35 to rotate and move in opposite directions.

[0033] This invention improves the internal structure of the mechanism 2. Specifically, the drive motor 25 is positioned between the connecting seat 26 and the intermediate seat 27. The connecting seat 26 is provided with a first gear groove 262 and a second gear groove 263 for positioning the first transmission gear 63 and the second transmission gear 64. The intermediate cover 281 is provided with multiple positioning posts for positioning the third transmission gear 65 and the fourth transmission gear 66. This makes the transmission mechanism run more smoothly and provides better positioning for the drive motor 25 and the power supply 23. Furthermore, the connection shaft 69 allows for more internal space in the mechanism 2, facilitating the positioning and installation of the drive motor 25 and the power supply 23, resulting in a more compact internal structure and higher space utilization.
