Technical Field

[0001] The present invention relates to the technical field of massagers, in particular to a massager. Background Art

[0002] With the improvement of living standards and the increasing pressure of life and work, healthcare products are becoming more and more popular. People are also investing more and more energy in their own health and comfort. Existing massage devices mostly use high-frequency vibration or rigid rotation to directly apply mechanical vibration to the massage area to achieve the purpose of relaxing muscles and relieving fatigue. However, this massage has a monotonous rhythm and rigid force, which may lead to excessive pressure or insufficient stimulation in some areas. Prolonged use can easily cause discomfort, resulting in the massage effect failing to meet the user's personalized needs. To this end, we propose a massager. Summary of the Invention

[0003] The present invention aims to provide a massager that addresses the aforementioned background art issues. Existing massage devices, most of which utilize high-frequency vibration or rigid rotation, directly apply mechanical vibration to the massaged area to achieve muscle relaxation and fatigue relief. However, these massage methods employ a monotonous rhythm and rigid force, which can lead to excessive or insufficient localized pressure. This can also cause discomfort over time, resulting in a massage effect that fails to meet the user's personalized needs.

A limiting groove is formed between the outer shell and the stroke shaft, and the limiting groove extends along the central axis direction of the stroke shaft. At least part of the movable part is located in the limiting groove. When the stroke shaft rotates, the movable part can move back and forth along the central axis direction of the stroke shaft.

[0009] The movable part is provided with a rolling cavity, and at least a portion of the ball can be inserted into the rolling cavity.

[0010] The rolling cavity can accommodate at least half of the volume of the ball.

[0011] Among them, along the central axis direction of the stroke shaft, the spiral groove has a height difference, and the height difference forms the stroke of the movable part.

[0012] Among them, the spiral grooves are connected end to end.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 4 The present invention provides a technical solution: a massager includes a shell 1, a driving member 2, a transmission assembly 3, a transmission assembly 3 and a plurality of movable parts 4. The driving member 2 is installed on the shell 1, and the transmission assembly 3 is installed on the shell 1. The driving member 2 is connected to the transmission assembly 3, and the driving member 2 can drive the transmission assembly 3 to move in a predetermined manner. The movable parts 4 are respectively connected to the transmission assembly 3, and through the transmission of the transmission assembly 3, the constraints of the shell 1 can be cooperated to enable the movable parts 4 to present an interlaced reciprocating motion. The interlaced reciprocating motion can be that the movable parts 4 move in a common direction, with one movable part 4 moving forward and the other movable part 4 moving backward, and move back and forth in an interlaced manner. The movable parts 4 can be two, three, four, five, etc., and can be set as needed.

[0026] The driving member 2 can be an electric motor to provide power for the massager, drive the transmission component 3 to move, and convert the rotational motion of the driving member 2 into an interlaced reciprocating motion of the movable member 4 to achieve massage of the massage area.

[0027] The housing 1 can provide a gripping space, and the gripping area of ​​the housing 1 is coated with soft rubber, so that it fits the palm of the user more closely and is more comfortable to hold. The housing 1 is formed with a receiving cavity, and the driving member 2 is installed in the receiving cavity of the housing 1.

[0028] The transmission assembly 3 includes a stroke shaft 31 and a ball 32. The driving member 2 is connected to the stroke shaft 31 and drives the stroke shaft 31 to rotate. The stroke shaft 31 is provided with a spiral groove 5. Each movable member 4 is connected to the spiral groove 5 through the ball 32. The ball 32 can roll in the spiral groove 5. A limiting groove 6 is formed between the outer shell 1 and the stroke shaft 31. The limiting groove 6 extends along the central axis of the stroke shaft 31. At least part of the movable member 4 is located in the limiting groove 6. When the stroke shaft 31 rotates, the movable member 4 can make a staggered reciprocating motion along the central axis of the stroke shaft 31. The driving member 2 drives the stroke shaft 31 to rotate around its own central axis. At least part of the movable member 4 is located in the limiting groove 6 to limit the movable member 4 from rotating with the stroke shaft 31. When the stroke shaft 31 rotates, under the joint action of the spiral groove 5 and the limiting groove 6, the movable member 4 can make a staggered reciprocating motion along the central axis of the stroke shaft 31.

[0029] The movable part 4 is provided with a rolling cavity 7 , and at least a portion of the ball 32 can be inserted into the rolling cavity 7 . The ball 32 can rotate freely in the rolling cavity 7 to reduce friction between the ball 32 and the movable part 4 .

[0030] The rolling cavity 7 can accommodate at least half of the volume of the ball 32, so that the connection between the ball 32 and the movable part 4 is more stable, and separation during movement is avoided.

[0031] Along the central axis of the stroke shaft 31 , the spiral groove 5 has a height difference, which forms the stroke of the movable part 4 . This design enables the movable part 4 to perform staggered reciprocating motion along the central axis of the stroke shaft 31 .

[0032] The spiral grooves 5 are connected end to end, forming a closed annular structure, so that the stroke shaft 31 can continuously drive the movable part 4 to perform reciprocating motion.

[0033] The limiting grooves 6 are arranged at intervals along the circumference of the stroke shaft 31; alternatively, a movable member 4 is correspondingly provided in each limiting groove 6, and the limiting grooves 6 are spaced at equal distances. This design ensures that each movable member 4 can move stably in the corresponding limiting groove 6.

[0034] The inner side of the housing 1 is provided with an isolation strip 8, and the limiting groove 6 is located between two adjacent isolation strips 8. This design can limit the movable part 4 to always move stably in the limiting groove 6 during movement, avoiding movement dislocation.

[0035] The outer side surface of the movable part 4 is wavy, and the wavy design can increase the contact area with the massage part and enhance the massage effect.

[0036] The periphery of each movable part 4 is wrapped with a flexible outer cover made of medical-grade silicone material, which has good biocompatibility, flexibility and durability, and can not only ensure the safety of use, but also improve the comfort during massage.

[0037] During use, the rotation of the driving member 2 drives the stroke shaft 31 of the transmission assembly 3 to rotate, so that the ball 32 can perform a circular rotational motion along the trajectory of the spiral groove 5 with the stroke shaft 31, and the ball 32 rotates freely in the rolling cavity 7, thereby driving the movable member 4 to move along the trajectory of the spiral groove 5. Because the movable member 4 is located in the limiting groove 6, the movable member 4 makes a staggered reciprocating motion along the central axis direction of the stroke shaft 31, and the surface of the movable member 4 is wavy, which makes the massage more comprehensive and in-depth, avoiding the limitations of a single massage method. At the same time, the staggered massage makes the force change softer and the massage level richer, greatly improving the comfort of the massage.
