[0012] The present application provides a massage device. Fig. 1 is a schematic view of the appearance of the massage device provided by the present application, Fig. 2 is a schematic view of the internal structure of the soft rubber body provided by the present application, and Fig. 3 is a schematic view of the state in which the rotary motor provided by the present application has rotated the eccentric rod from 0° to 180°. 1, 2, 3, and 4, the massage device includes an inner housing 10, a rotary motor 20, an eccentric connection assembly 30, a massage head 40, a vibration motor 50, and a soft rubber body 60. Here, the rotary motor 20 is provided in the inner housing 10 and has an output shaft 21, which is parallel to a first direction (the X direction shown in the drawings). Illustratively, the rotary motor 20 is a rotary motor equipped with a reducer, and the output shaft 21 is the output end of the reducer.

[0013] The eccentric connection assembly 30 is connected to the output shaft 21 of the rotary motor 20, and the massage head 40 is connected to the eccentric connection assembly 30. The massage head 40 is generally tilted relative to a first direction. The eccentric connection assembly 30 is used to eccentrically rotate the entire massage head 40 under the driving of the rotary motor 20. The vibration motor 50 is provided in the massage head 40 and is used to vibrate the massage head 40. A storage chamber 61 is provided in the soft rubber body 60, and the inner housing 10 and the massage head 40 are provided in the storage chamber 61. A cover body 62 is provided at one end of the soft rubber body 60 close to the massage head 40.

[0014] When the user uses the massage device, he places the cover body 62 over his chest and then starts the device, the eccentric connection assembly 30 causes the entire massage head 40 to rotate eccentrically, and at the same time the massage head 40 vibrates. As a result, when the massage head 40 comes into contact with the chest, it kneads and vibrates the chest, strengthens the stimulation to the muscle tissue, and achieves a better massage effect. In addition, the various massage methods can further satisfy the user's new sensations and experiences.

[0015] In some embodiments, the massage device further includes a massage sleeve 70, which is detachably attached to the massage head 40 and has massage protrusions 71 on its surface. The massage sleeve 70 can contact a part of the human body through the massage protrusions 71. The massage head 40 can contact a part of the human body through the massage protrusions 71 of the massage sleeve 70, thereby achieving a better contact massage effect. Here, a plurality of massage sleeves 70 can be arranged, and different massage sleeves 70 have massage protrusions 71 of different shapes, and the specific shapes may be one or a combination of lip-shaped, wave-shaped, striped, etc. The user can select a massage sleeve 70 to attach to or detach from the massage head 40, and then use the massage head 40 of the corresponding shape to perform massage, thereby meeting different user needs.

[0016] In the example of the present application, both the soft rubber body 60 and the massage sleeve 70 are made of silicone rubber, the soft rubber body 60 encases the inner housing 10 and the massage head 40, and the massage sleeve 70 is sleeved onto the massage head 40 via the soft rubber body 60. In other embodiments, the soft rubber body 60 and the massage sleeve 70 may be made of other materials, and the massage sleeve 70 may be configured to be directly sleeved onto the massage head 40, and the present application is not limited thereto.

[0017] FIG. 5 is a schematic diagram of the internal structure of the inner housing and the massage head provided by the present application. Referring to FIG. 5 , in some embodiments, the massage device further comprises a battery 11, a charging terminal 12, a circuit board 13 and an operation button 14, wherein the battery 11, the rotary motor 20, the vibration motor 50, the charging terminal 12 and the operation button 14 are all electrically connected to the circuit board 13, the battery 11 and the circuit board 13 are disposed within the inner housing 10, and the charging terminal 12 is fitted into the inner housing 10 with a portion exposed to the outside of the soft rubber body 60.

[0018] For example, a control module is integrated into the circuit board 13, and the control module may be a control circuit or a control chip. The circuit board 13 is used to control the operation of electronic modules such as the battery 11, charging terminal 12, rotation motor 20, and vibration motor 50. The battery 11 stores power and is used to supply power to the rotation motor 20 and the vibration motor 50. A through-hole is formed in the inner housing 10 to expose the operation button 14, and a touch-sensitive portion 64 corresponding to the operation button 14 is provided on the soft rubber body 60, so that a user can press the touch-sensitive portion 64 to press the operation button 14.

[0019] The charging terminal 12 is used to contact the power terminal of an external power source and allow the external power source to charge the battery 11. The charging terminal 12 may be a charging pin, and the soft rubber body 60 has a through-hole for the charging pin to pass through, and the charging terminal 12 and the soft rubber body 60 are hermetically connected. The hermetically connected connection may be fixed with a sealing adhesive or an interference fit, as long as the internal components are sealed and a completely waterproof effect is achieved. In other embodiments, the charging terminal 12 may be a charging interface, a wireless charging module, etc., and this application is not limited thereto.

[0020] In the examples of the present application, the surface of the massage head 40 facing the internal housing 10 is defined as the top surface, and the surface of the massage head 40 away from the internal housing 10 is defined as the bottom surface. The massage head 40 is generally tilted relative to the first direction, and the bottom surface of the massage head 40 is flat. However, when observed from a third direction (the Y direction shown in the figure) perpendicular to the first direction, the bottom surface of the massage head 40 is not flat relative to the third direction. This causes the massage head 40 to rotate eccentrically rather than simply moving in a circular motion, resulting in the effect of the bottom surface of the massage head 40 floating up and down. For example, the massage head 40 is composed of a left mounting housing and a right mounting housing, and the left mounting housing and the right mounting housing are assembled to form an integrated massage head 40, and the vibration motor 50 is mounted inside the massage head 40.

[0021] Figure 6 is an exploded view of the internal housing provided by the present application, Figure 7 is a schematic view of the internal structure of the massage head provided by the present application, and Figure 8 is an exploded view of the massage head and internal housing provided by the present application. 6 to 8, in some embodiments, the eccentric connection assembly 30 includes an eccentric rod 31 of the connecting massage head 40 and a positioning rod 32 for limiting the rotation of the massage head 40. Here, the eccentric rod 31 has a first section 311 and a second section 312, and the first section 311 is parallel to the first direction and fixed to the output shaft 21. For example, a rotation port is opened in a portion of the inner housing 10 close to the output shaft 21, and the first section 311 enters the inner housing 10 through the rotation port and is fixedly connected coaxially to the output shaft 21.

[0022] Specifically, the massage head 40 is rotatably connected to the second stage 312, and the rotation axis between the massage head 40 and the second stage 312 is parallel to the second direction. The second stage 312 is provided at an angle to the first direction, and the second stage 312 is connected to the massage head 40. The second stage 312 is provided coaxially with the massage head 40, so that the massage head 40 as a whole is provided at an angle to the first direction. It is defined that the second stage 312 is parallel to the second direction (the X' direction shown in the figure), and an angle is formed between the second direction and the first direction. It should be noted that the second direction is the orientation direction of the second stage 312. When the rotary motor 20 rotates the eccentric rod 31, the second stage 312 performs a circular motion, forming a conical motion trajectory, and the orientation direction of the second stage 312 also changes. Therefore, it should be understood that the illustrated X' direction is an exemplary description of the second stage 312 rotated to a specific angle, and does not limit the state of the second stage 312.

[0023] For example, the second step 312 is cylindrical, and a positioning protrusion 313 is formed along the circumference of the second step 312. A rotation groove 41 is formed at the top of the massage head 40, and a recessed fitting groove 411 is formed in the center of the groove wall of the rotation groove 41. The second step 312 as a whole is accommodated in the rotation groove 41, and the positioning protrusion 313 is accommodated in the fitting groove 411. This allows the massage head 40 to rotate relatively around the axis of the second step 312 together with the eccentric rod 31, and the positioning protrusion 313 and the fitting groove 411 are positioned and aligned to prevent the second step 312 and the massage head 40 from separating.

[0024] Specifically, a gap is formed between the positioning rod 32 and the output shaft 21 in the third direction, so that the positioning rod 32 is eccentrically disposed relative to the output shaft 21. The positioning rod 32 is connected between the inner housing 10 and the massage head 40, and is used to position the massage head 40 along the first direction. For example, a positioning hole 42 is opened at the top of the massage head 40, one end of the positioning rod 32 is fixedly connected to the inner housing 10, and the other end of the positioning rod 32 is inserted into the positioning hole 42 along the first direction, and the inner area of ​​the positioning hole 42 is larger than the cross-sectional area of ​​the positioning rod 32. A wiring groove 321 is provided in the positioning rod 32, and the wiring groove 321 is used to pass wiring between the vibration motor 50 and the circuit board 13.

[0025] When the rotary motor 20 drives the eccentric rod 31 to rotate as a whole around the output shaft 21, the eccentric rod 31 moves as follows: the first stage 311 rotates around the axis of the output shaft 21, and the second stage 312 moves circumferentially around the axis of the output shaft 21, forming a conical movement path. At the same time, the positioning rod 32 restricts the rotation of the massage head 40, so that the massage head 40 and the second stage 312 rotate relative to each other. During this process, the massage head 40 as a whole oscillates according to the circumferential movement of the second stage 312. Under the positioning action of the positioning rod 32, the positioning rod 32 can be extended or retracted from the positioning hole 42, and each part of the massage head 40 floats up and down, achieving the effect of eccentric rotation of the massage head 40.

[0026] For ease of understanding, the following will take the states when the eccentric rod 31 is at different angles as examples. The left side of the massage head 40 is defined as region A, and the right side of the massage head 40 is defined as region B. When the rotary motor 20 rotates the eccentric rod 31 to 0°, part A of the massage head 40 protrudes downward relative to part B of the massage head 40. When the rotary motor 20 rotates the eccentric rod 31 to 180°, part B of the massage head 40 protrudes downward relative to part A of the massage head 40. As a result, when the rotary motor 20 rotates the eccentric rod 31 from 0° to 360°, part A and part B alternately float up and down, achieving the effect of eccentric rotation.

[0027] It should be noted that in this application, the number of positioning rod 32 is one, and the positioning rod 32 is fixed to the internal housing 10; in other embodiments, there may be multiple positioning rods 32, and the multiple positioning rods 32 are distributed at intervals around the eccentric rod 31; in another embodiment, the positioning rod 32 may be fixed to the massage head 40 and extend through the internal housing 10, as long as the positioning rod 32 can achieve the rotation restriction and linear positioning effect of the massage head 40, and this application is not limited to this.

[0028] It should be noted that the present application utilizes the rotational connection relationship between the eccentric rod 31 and the massage head 40, and uses the positioning rod 32 to limit the rotation of the massage head 40 and position it in a linear direction (i.e., the first direction), thereby achieving the effect of eccentric rotation of the massage head 40 under the action of the eccentric rod 31. In other embodiments, the massage head 40 is directly and fixedly connected to the massage head 40, and the effect of eccentric rotation of the massage head 40 can also be achieved even if the limiting and positioning of the massage head 40 by the eccentric rod 31 is omitted, and it should be noted that the present application is not limited thereto.

[0029] In some embodiments, the inner housing 10 is composed of a left fixed housing and a right fixed housing, which are assembled to form the integral inner housing 10. A sealing lid 80 is provided on the inner housing 10, and the sealing lid 80 covers the mounting opening 63. The mounting opening 63 is opened in the soft rubber body 60, and the mounting opening 63 communicates with the receiving chamber 61. The sealing lid 80 and the soft rubber body 60 are sealed together, and the sealing connection may be by sealing adhesive or interference fitting, which achieves the effect of sealing the internal components and making them completely waterproof.

[0030] For example, the sealing lid 80 and the inner housing 10 are fixed by snap fitting, and the mounting hole 63 is opened at one end of the soft rubber body 60 away from the massage head 40, that is, the mounting hole 63 is opened at the top of the soft rubber body 60. In other embodiments, the sealing lid 80 and the inner housing 10 may be fixed by plugging, gluing, etc. In another embodiment, the mounting hole 63 may be opened on the side of the soft rubber body 60, and the position of the sealing lid 80 may be adjusted accordingly, and the present application is not limited thereto. It should be noted that in the assembly process of the massage device, the inner housing 10 and the massage head 40 can be first inserted into the soft rubber body 60 through the mounting opening 63, and then the sealing lid 80 can be attached to the inner housing 10 from the outside of the soft rubber body 60 to close the mounting opening 63 with the sealing lid 80, and a sealing process can be performed between the sealing lid 80 and the soft rubber body 60. This makes the assembly method simpler and more convenient, and improves production efficiency.

[0031] Finally, the above examples are not limiting and are only used for the purpose of describing the technical solutions of the present application, and the present application is described in detail with reference to preferred embodiments, but it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solutions of the present application without departing from the spirit and scope of the technical solutions of the present application.
