Description

Technical Field

[0001] This utility model relates to the field of massagers, and in particular to a telescopic swing vibration device for a massager. Background Technology

[0002] A massager is an ergonomically designed device used to massage parts of the body to achieve relaxation, relieve pain, promote blood circulation, or improve bodily functions. It utilizes various techniques such as kneading, tapping, vibration, and heat application to simulate the effects of human hand massage, helping users relieve fatigue, improve sleep quality, and enhance the body's immunity. Massagers come in many varieties and can be categorized according to different massage areas, functions, and usage methods. For example, there are massagers specifically designed for the neck, shoulders, back, waist, and legs; massagers designed for specific symptoms such as cervical spondylosis, frozen shoulder, and lumbar muscle strain; and portable massagers for convenient use anytime, anywhere.

[0003] Current massagers primarily utilize a swingable massage component positioned at the front end of a sliding housing, coupled with a swing shaft connected to a screw. This causes the massage component to swing back and forth, enabling simultaneous extension, retraction, and oscillation. However, the massage component in this device cannot rotate and lacks vibration functionality, failing to meet user needs. Therefore, it is necessary to research a solution to address these issues. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a telescopic swing vibration device for a massager, which can effectively solve the problem that existing massage components can only telescopically swing but cannot rotate and vibrate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A telescopic rocking vibration device for a massager includes a drive mechanism, a fixed housing, a screw, a sliding housing, a rocking shaft, and a vibrating housing. The fixed housing is fixedly connected to the drive mechanism and has a front-to-back extending receiving cavity.

[0017] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a drive mechanism 10, a fixed shell 20, a screw 30, a sliding shell 40, a rocking shaft 50, and a vibrating shell 60.

[0018] The drive mechanism 10 includes a gearbox 11 and a drive motor 12. The gearbox 11 includes a housing 111 and a gear set 112 disposed within the housing 111. The drive motor 12 is fixed to the housing 111, and its output shaft is connected to the input end of the gear set 112, driving the gear set 112 to rotate. The housing 111 includes a shell 1111 and a motor mount 1112. The motor mount 1112 is fixed to the rear end of the shell 1111 and together with the shell 1111 forms a mounting cavity 101. The gear set 112 is installed in the mounting cavity 101, and the drive motor 12 is fixed to the motor mount 1112. Additionally, the gear set 112 has an output shaft 1121 that extends out from the front end of the shell 1111.

[0019] The fixed housing 20 is fixedly connected to the drive mechanism 10. The fixed housing 20 has a front-to-back extending accommodating cavity 21. A guide groove 22 is provided on the side of the fixed housing 20, which extends front-to-back and communicates with the accommodating cavity 21. In this embodiment, the outer contour of the fixed housing 20 is a hexagonal prism structure, and the rear end of the fixed housing 20 is fixedly connected to the front end face of the outer shell 1111 by screws (not shown in the figure).

[0020] The screw 30 is rotatably disposed in the accommodating cavity 21. A closed annular groove 31 is recessed on the outer surface of the screw 30. The rear end of the screw 30 is connected to the output end of the drive mechanism 10, and the screw 30 is driven to rotate by the drive mechanism 10. In this embodiment, the output end of the gear set 112 is connected to the rear end of the screw 30. Specifically, a first connecting hole 32 is formed at the center of the rear end face of the screw 30, and the front end of the output shaft 1121 is inserted into the first connecting hole 32 for fixed connection. Furthermore, a second connecting hole 33 is formed at the front end of the screw 30; this second connecting hole 33 is a non-circular hole.

[0021] The sliding shell 40 is slidably fitted onto the fixed shell 20. The sliding shell 40 has a cavity 401 that matches the outer contour of the fixed shell 20. A shaft hole 402 is formed at the center of the front end of the sliding shell 40, communicating with the cavity 401. The sliding shell 40 also has a recess 403 within it, in which a rolling ball 70 is embedded. The ball 70 passes through a guide groove 22 and is embedded in a track groove 31. Specifically, the sliding shell 40 includes a main body 41 and a side cover 42. The outer surface of the main body 41 has a mounting hole 404 for installing the ball 70. The side cover 42 is fixed to the outer surface of the main body 41 and covers the opening of the mounting hole 404, forming the aforementioned recess 403.

[0022] The rocker shaft 50 is curved and is an elastically straightening shaft. The rear end of the rocker shaft 50 passes through the shaft hole 402 and is fixedly connected to the front end of the screw 30. The rocker shaft 50 rotates with the screw 30, and it slides within the shaft hole 402. The sliding shell 40 slides back and forth to control the straightening or bending of the rocker shaft 50. In this embodiment, the rear end of the rocker shaft 50 is connected to the front end of the screw 30 via a connecting member 51. The connecting member 51 is located inside the sliding shell 40 and is fixedly formed at the rear end of the rocker shaft 50. The connecting member 51 is inserted into the second connecting hole 33 for a tight fit, resulting in a simple structure and convenient assembly.

[0023] The vibrating housing 60 is fixed to the front end of the rocker shaft 50 and located outside the sliding housing 40. Specifically, the vibrating housing 60 includes a main housing 61 and a vibrating motor 62 disposed within the main housing 61. The main housing 61 includes a front housing 611 and a rear cover 612. The front housing 611 and the rear cover 612 are spliced ​​together to form a receiving cavity 601, and the vibrating motor 62 is fixed within the receiving cavity 601.

[0024] The working principle of this embodiment is described in detail below: During operation, this product is installed in the massager. When the drive motor 12 is powered on, it drives the gear set 112 in the gearbox 11 to rotate. The gear set 112 outputs power to rotate the screw 30. The rotation of the screw 30 causes the ball bearing 70 to move along the track groove 31 and guide groove 22. This causes the ball bearing 70 to move the sliding shell 40 back and forth relative to the fixed shell 20. The sliding shell 40 slides back and forth along the rocking shaft 50, controlling the straightening or bending of the rocking shaft 50. This causes the front end of the rocking shaft 50 to rock back and forth. The vibrating shell 60 rocks back and forth with the front end of the rocking shaft 50. At the same time, the rocking shaft 50 rotates under the drive of the screw 30, and the vibrating shell 60 also rotates with the rocking shaft 50, thus achieving continuous rotation and rocking of the vibrating shell 60 to provide contact massage to the body parts. In addition, the vibration motor 62 can be turned on to make the vibrating shell 60 generate high-frequency vibration for simultaneous vibration massage.

[0025] The key design feature of this invention is that by using a vibrating shell, the product possesses a vibration function. Simultaneously, a swing shaft connects the vibrating shell to a screw, which drives the swing shaft to rotate, allowing the vibrating shell to rotate. Furthermore, a sliding shell extends and retracts relative to the fixed shell, controlling the straightening or bending of the swing shaft, thus enabling the vibrating shell to swing. Therefore, the vibrating shell can swing and rotate, providing a vibration function for better massage of body parts and meeting user needs.

[0026] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
