Description

Technical Field

[0001] This invention relates to the field of massage device technology, and in particular to a massage device. Background Technology

[0002] Massagers are a type of massage product that has become increasingly popular in recent years. Their basic principle is that a motor drives an eccentric wheel to rotate, which in turn causes the transmission components to move in an eccentric cam motion, thereby achieving repeated impacts from the massage head to massage the human body.

[0003] However, when existing massagers are in operation, the motor and eccentric shaft are prone to eccentric displacement, which causes the massage head to vibrate and the vibration to intensify when the motor and eccentric wheel rotate, resulting in greater noise and shaking, thus leading to poor massager performance. Summary of the Invention

[0004] The main objective of this invention is to provide a massager that, by setting up a support member, restricts the massage head assembly from making eccentric movements within a certain range, thereby preventing the massage head assembly from shifting eccentrically, effectively reducing noise and shaking, and thus improving the massage effect of the massager.

[0038] This invention proposes a massager that, by setting up a support member, can limit the eccentric movement of the massage head assembly within a certain range, thereby preventing the massage head assembly from shifting eccentrically, effectively reducing noise and shaking, and thus improving the massage effect of the massager.

[0039] Please refer to Figures 1 to 6 The specific structure of the massager 10 proposed in this invention will be described below in specific embodiments. In one embodiment of this invention, the massager 10 includes:

[0040] A first housing 1, wherein a receiving cavity 11 with an opening 111 is formed inside the first housing 1;

[0041] Massage head 22 assembly 2, wherein the massage head 22 assembly 2 is mounted in the opening 111;

[0042] A drive assembly 3, disposed within the receiving cavity 11, and connected to the massage head 22 assembly 2, drives the massage head 22 assembly 2 to perform eccentric movement; and

[0043] The support member 4 has one end installed in the receiving cavity 11 and the other end exposed in the opening 111, and is movably limited within the massage head 22 assembly 2 to limit the range of eccentric movement of the massage head 22 assembly 2.

[0044] In this embodiment, the massager 10 includes a first housing 1, a massage head 22 assembly 2, and a drive assembly 3. The first housing 1 has a receiving cavity 11 with an opening 111. The massage head 22 assembly 2 is installed in the opening 111, thus forming the overall structure of the massager 10. The massage head 22 assembly 2 is used to act on the human body. Simultaneously, the drive assembly 3 is installed in the receiving cavity 11 and is connected to the massage head 22 assembly 2, causing the massage head 22 assembly 2 to perform eccentric movement, thereby realizing the massage function of the massage head 22 assembly 2. Therefore, when the massager 10 is working, the drive assembly 3 can drive the massage head 22 assembly 2 to act on the massage area, stimulating various receptors in muscles, tendons, and joint capsules in a rotary vibration manner, reducing myogenic pain, increasing the pain threshold, and reducing lactic acid accumulation. Especially after exercise, using the massager 10 can relieve soreness and shorten the muscle recovery time after exercise.

[0045] Specifically, to facilitate limiting the movement of the massage head 22 assembly 2 within a certain range, the massager 10 also includes a support member 4. One end of the support member 4 is installed in the receiving cavity 11, and the other end of the support member 4 is exposed in the opening 111 and is movably limited within the massage head 22 assembly 2 to limit the amplitude of the eccentric movement of the massage head 22 assembly 2. Thus, when the driving component 3 drives the massage head 22 assembly 2 to move, the limitation of the support member 4 allows the massage head 22 assembly 2 to move within a certain range, thereby achieving vibration of the massage head 22 assembly 2 and facilitating the massage head 22 assembly 2 to act on the human body. It should be noted that, to facilitate the user's grip on the massager 10, the first housing 1 is provided with a grip portion 114, which is provided with multiple anti-slip protrusions to allow the user to stably hold the massager 10.

[0046] Please refer to Figures 2 to 6 In an optional embodiment, the massage head 22 assembly 2 includes a second housing 21 and a plurality of massage heads 22. The second housing 21 is connected to the first housing 1, and the plurality of massage heads 22 are spaced apart along the outer peripheral wall of the second housing 21. The drive assembly 3 is driven to be connected to the second housing 21.

[0047] The support member 4 forms a limiting part 42, and the second housing 21 forms a limiting groove 213. The limiting part 42 is movably inserted into the limiting groove 213 to limit the eccentric movement range of the second housing 21.

[0048] In this embodiment, to facilitate the connection between the massage head 22 assembly 2 and the first housing 1, the massage head 22 assembly 2 includes a second housing 21 and a plurality of massage heads 22. The second housing 21 is mounted on the first housing 1 and connects with the first housing 1 to form a receiving cavity 11. It should be noted that the connection between the second housing 21 and the first housing 1 can be by adhesive bonding, screw connection, or a combination of both. Other fixing methods are also possible and are not limited here. It is understood that since the second housing 21 and the first housing 1 enclose the receiving cavity 11, one of them can form a receiving space, and the other covers the opening 111 of the receiving space, thereby ensuring the volume of the receiving cavity 11.

[0049] Specifically, a cavity 211 with an opening 111 is formed inside the second housing 21. Multiple massage heads 22 are spaced apart along the outer peripheral wall of the second housing 21, and a drive assembly 3 is connected to the second housing 21 to drive the movement of the multiple massage heads 22. It should be noted that the shape of each massage head 22 is different. In this embodiment, three massage heads 22 are provided. The surface of the massage head 22 that contacts the human body is designated as the contact surface. The contact surface of each massage head 22 is different; it can be a plane, a slightly curved surface, or a circle. Furthermore, the contact area of ​​the contact surface of each massage head 22 is different, thus enabling the massager 10 to have at least one physical massage method. Therefore, when the massager 10 is working, it can provide multiple physical massage effects when impacting the same massage area, not only enriching the massage effects but also meeting diverse massage needs. It should be further noted that the hardness or material of each massage head 22 may be the same or different. For example, one massage head 22 may be round, hard and smooth, while another massage head 22 may be flat, soft and smooth. The material of each massage head 22 may be plastic, silicone, etc., and each massage head 22 may have a certain height difference so that each massage head 22 can act on the massage area in sequence, thereby providing different massage effects and massage functions.

[0050] Furthermore, in order to facilitate the connection between the support member 4 and the second housing 21, a limiting part 42 is formed in the support member 4, and a limiting groove 213 is formed in the second housing 21. The limiting part 42 is movably inserted into the limiting groove 213 to limit the eccentric movement of the second housing 21. That is, the shapes of the limiting part 42 and the limiting groove 213 are mutually adapted, so that the limiting part 42 can be stably inserted into the limiting groove 213.

[0051] Please refer to Figures 2 to 6 In an optional embodiment, a cavity 211 with a mating interface is formed inside the second housing 21, and the support member 4 includes a mounting part 41 and a limiting part 42 provided on one side of the mounting part 41. The mounting part 41 is mounted on the inner peripheral wall of the receiving cavity 11.

[0052] The inner peripheral wall of the cavity 211 is provided with a flange 212, and the flange 212 is provided with a limiting groove 213. The limiting part 42 is inserted into the limiting groove 213, thereby realizing a stable connection between the support member 4 and the second housing 21.

[0053] In this embodiment, a cavity 211 with an interface is formed inside the second housing 21. When the first housing 1 and the second housing 21 are installed, the interface and opening 111 are aligned and installed, thereby forming a sealed cavity between the cavity 211 and the receiving cavity 11, ensuring the normal operation of the massager 10. Meanwhile, the support member 4 includes a mounting part 41 and a limiting part 42 located on one side of the mounting part 41. The mounting part 41 is installed on the inner peripheral wall of the receiving cavity 11. It should be noted that a mounting flange 112 is formed on the inner peripheral wall of the receiving cavity 11 near the opening 111. The mounting flange 112 has a mounting groove 1121 for mounting the mounting part 41. The outer peripheral wall of the mounting part 41 has multiple first limiting grooves 41a and multiple first limiting protrusions 41b, which are spaced apart on the outer peripheral wall of the mounting part 41. Each first limiting groove 41a... As each of the first limiting protrusions 41b is arranged in the same direction along the radial direction of the support member 4, similarly, the inner peripheral wall of the cavity 211 is provided with a second limiting protrusion 11b that matches the first limiting groove 41a, and the outer peripheral wall of the mounting flange 112 is provided with a second limiting groove 11a that matches the first limiting protrusion 41b. Thus, when the support member 4 is installed in the receiving cavity 11, the mutual cooperation between the first limiting groove 41a and the second limiting protrusion 11b, and between the second limiting groove 11a and the first limiting protrusion 41b, ensures that the support member 4 can be stably installed in the receiving cavity 11, and is not prone to displacement. At the same time, a pressing member is also provided, which can be installed on the mounting flange 112 by screws or the like, to lock the mounting part 41 in the receiving cavity 11.

[0054] Specifically, the inner peripheral wall of the cavity 211 is provided with a flange 212, and a limiting groove 213 is formed on the flange 212. When the massage head 22 assembly 2 is installed on the first housing 1, the limiting part 42 on the support member 4 is inserted into the limiting groove 213 on the flange 212 to achieve connection between the support member 4 and the second housing 21. Thus, under the drive of the drive component 3 and the constraint of the support member 4, the rotational movement of the massage head 22 assembly 2 is effectively restricted, while vibration of the massage head 22 is allowed. It should be noted that the support member 4 is annularly arranged, and the support member 4 has a through hole 4a for the drive component 3 to pass through. Similarly, the flange 212 and the mounting flange 112 also have corresponding through holes 4a, so that the drive component 3 can be stably driven and connected to the second housing 21.

[0055] Please refer to Figure 4 and Figure 6 In an optional embodiment, a plurality of limiting portions 42 are provided, and the plurality of limiting portions 42 are spaced apart along the periphery of the mounting portion 41;

[0056] The limiting groove 213 is provided in multiple ways, and the multiple limiting grooves 213 are spaced apart on the periphery of the flange 212. Each limiting part 42 is inserted into each limiting groove 213. Through the cooperation between the multiple limiting parts 42 and the multiple limiting grooves 213, the support member 4 can effectively limit the amplitude generated when the massage head 22 assembly 2 makes eccentric movements.

[0057] In this embodiment, in order to further limit the amplitude generated when the massage head 22 assembly 2 makes eccentric movements, multiple limiting parts 42 are provided, for example, two, three or more, and multiple limiting parts 42 are spaced apart along the periphery of the mounting part 41. Similarly, multiple limiting grooves 213 are also provided, for example, two, three or more, and multiple limiting grooves 213 are spaced apart on the periphery of the flange 212. Each limiting part 42 is movably limited within each limiting groove 213 to achieve approximate positioning between the support member 4 and the second housing 21, thereby effectively limiting the rotational movement of the massage head 22 through the limiting parts 42 and allowing the massage head 22 to vibrate. In this embodiment, six limiting parts 42 are provided, and similarly, six limiting grooves 213 are also provided. The six limiting parts 42 are spaced apart along the periphery of the mounting part 41, and a certain distance is provided between each pair of adjacent limiting parts 42. Similarly, the six limiting grooves 213 are spaced apart on the periphery of the flange 212, so that each limiting part 42 is inserted into each limiting groove 213. Adjacent limiting parts 42 have a certain deformation space, thereby effectively restricting the rotational movement of the massage head 22 assembly 2.

[0058] It should be noted that the support component 4 is a one-piece molded structure, which ensures structural strength and stability.

[0059] Please refer to Figure 4 and Figure 6 In an optional embodiment, each of the limiting portions 42 includes a first protruding end 421 and a second protruding end 422 connected to each other. The first protruding end 421 is connected to the mounting portion 41, and the second protruding end 422 is inserted into the limiting groove 213. The cross-sectional area of ​​the first protruding end 421 is larger than the cross-sectional area of ​​the second protruding end 422, and the opening 111 of the limiting groove 213 is larger than the cross-sectional area of ​​the second protruding end 422.

[0060] In this embodiment, in order to facilitate the connection between the limiting part 42 and the limiting groove 213, each limiting part 42 includes a first protruding end 421 and a second protruding end 422 connected to each other. The first protruding end 421 is connected to the mounting part 41, and the second protruding end 422 is inserted into the limiting groove 213. Therefore, when the massage head 22 assembly 2 rotates, the second protruding end 422 plays a limiting role, so that the massage head 22 assembly 2 makes a large-amplitude eccentric movement and realizes the vibration movement of the massage head 22, thereby realizing the massage effect of the massager 10.

[0061] Specifically, to facilitate the connection between the second protruding end 422 and the limiting groove 213, the cross-sectional area of ​​the first protruding end 421 is larger than that of the second protruding end 422, the opening 111 of the limiting groove 213 is larger than that of the second protruding end 422, and the cross-sectional area of ​​the first protruding end 421 is larger than that of the opening 111 of the limiting groove 213. Thus, the first protruding end 421 abuts against the outer periphery of the limiting groove 213, while the second protruding end 422 is inserted into the limiting groove 213. Furthermore, the opening 111 of the limiting groove 213 is larger than the cross-sectional area of ​​the second protruding end 422, resulting in a certain gap between the limiting groove 213 and the second protruding end 422. This facilitates the deformation of the second protruding end 422, providing a certain space for the deformation of the second protruding end 422, thereby ensuring that the second protruding end 422 can effectively limit the massage head 22 assembly 2 from making large-amplitude eccentric movements and realize the vibration movement of the massage head 22, thereby achieving the massage effect of the massager 10.

[0062] Please refer to Figures 1 to 6 In an optional embodiment, the support member 4 is made of a flexible material, which gives the support member 4 a certain deformation capability, thereby effectively limiting the massage head 22 assembly 2 from making large-scale rotational movements.

[0063] In this embodiment, the support member 4 is made of a flexible material, thus possessing a certain deformation buffering capacity. Therefore, when the drive component 3 drives the massage head 22 assembly 2 to move, under the deformation of the support member 4, the massage head 22 assembly 2 does not undergo large-amplitude rotational movement, causing each massage head 22 to vibrate, thereby realizing the massage function of the massager 10. It should be noted that the flexible material is preferably rubber or silicone. Of course, other flexible materials can also be used, and this application does not limit them.

[0064] Please refer to Figure 2 In an optional embodiment, the driving component 3 includes a driving motor 31 and a transmission component 32. The transmission component 32 includes a transmission seat 321 and an eccentric shaft 322. The driving motor 31 is driven and connected to the transmission seat 321. One end of the eccentric shaft 322 is connected to the end of the transmission seat 321 away from the driving motor 31, and the other end of the eccentric shaft 322 is connected to the second housing 21. Thus, the vibration movement of the massage head 22 is realized by driving the driving motor 31, the transmission seat 321, and the eccentric shaft 322, thereby realizing the massage effect of the massager 10.

[0065] In this embodiment, the drive assembly 3 includes a drive motor 31 and a transmission component 32. The drive component is installed within the receiving cavity 11. Specifically, the drive motor 31 is mounted within the receiving cavity 11 via a motor bracket. The transmission component 32 includes a transmission seat 321 and an eccentric shaft 322. The output shaft of the drive motor 31 is connected to the transmission seat 321, while one end of the eccentric shaft 322 is connected to the end of the transmission seat 321 away from the drive motor 31, and the other end of the eccentric shaft 322 is connected to the second housing 21, thereby achieving the rotational movement of the massage head 22. It should be noted that the drive assembly 3 also includes a bearing 33, which is installed within the second housing 21. The end of the eccentric shaft 322 away from the transmission seat 321 is connected to the bearing 33, thereby achieving the connection between the eccentric shaft 322 and the second housing 21. It should be noted that the drive motor drives the massage head to a speed of 10,000 revolutions per minute, achieving high-speed operation of the massage head and effectively improving the massage effect of the massager.

[0066] Specifically, the massager 10 also includes a cooling fan 8, which is mounted on the transmission base 321. Thus, when the drive motor 31 drives the transmission base 321 to rotate, it can also drive the cooling fan 8 to rotate. In order to facilitate air intake, the housing has multiple vent holes 113 on the outer peripheral wall near the cooling fan 8. At the same time, ventilation grooves for airflow are opened on the mounting flange 112 and the pressing member. Multiple ventilation grooves are provided, and multiple ventilation grooves are arranged at intervals on the periphery of the mounting flange 112. This allows the airflow generated by the cooling fan 8 to enter the sealed cavity formed by the receiving cavity 11 and the cavity 211, so as to remove the heat generated by the eccentric shaft 322 and other components, and ensure the normal operation of each component.

[0067] Please refer to Figure 2 and Figure 5 In an optional embodiment, the transmission seat 321 has a groove 3211 at the end away from the drive motor 31, and the eccentric shaft 322 is inserted into the groove 3211, thereby realizing a stable connection between the transmission seat 321 and the eccentric shaft 322, so that the drive motor 31 can smoothly drive the eccentric shaft 322 to rotate.

[0068] In this embodiment, to facilitate the connection between the transmission seat 321 and the eccentric shaft 322, a groove 3211 is provided at the end of the transmission seat 321 facing away from the drive motor 31. One end of the eccentric shaft 322 is installed in the groove 3211, thereby realizing the installation connection between the eccentric shaft 322 and the transmission seat 321. It should be noted that the shape of the groove 3211 is adapted to the shape of the eccentric shaft 322, and can be elongated or square. Here, the groove 3211 is an elongated hole with a rectangular cross-sectional area, and the end of the eccentric shaft 322 near the transmission seat 321 is also elongated, so that the transmission seat 321 can smoothly drive the eccentric shaft 322 to rotate.

[0069] It should be noted that, in order to ensure a stable connection between the transmission seat 321 and the eccentric shaft 322, a pad can be provided in the groove 3211 to make the connection between the two more secure, so that the transmission seat 321 can smoothly drive the eccentric shaft 322 to rotate. The pad can be made of rubber or other materials, which are not limited in this application.

[0070] Please refer to Figure 2 and Figure 3 In an optional embodiment, the massager 10 further includes a counterweight 5, which is installed on the periphery of the eccentric shaft 322 near the end of the second housing 21 to balance the eccentric force of the eccentric shaft 322 during rotation. This makes the operation of the entire massager 10 more stable, thereby offsetting the temperature rise and bearing wear caused by the unidirectional force generated by centrifugal force, effectively reducing noise and shaking, and thus improving the massage effect of the massager. It should be noted that the connection between the eccentric shaft 322 and the counterweight 5 can be by bonding or welding, or by a combination of bonding and welding. Of course, other fixed connection methods are also possible and are not limited here.

[0071] Please refer to Figure 1 and Figure 2In an optional embodiment, the massager 10 further includes a control component 6 and a button 7. The control component 6 is installed on the bottom wall of the receiving cavity 11, and the button 7 is at least partially exposed on the outer peripheral wall of the first housing 1. The control component 6 is electrically connected to the drive assembly 3 and the button 7, thereby enabling the drive motor 31 to be started or stopped through the button 7 and the control component 6, thereby controlling the operation of the massager 10.

[0072] In this embodiment, the massager 10 also includes a control component 6 and a button 7. The control component 6 is installed on the bottom wall of the receiving cavity 11 and is electrically connected to the drive component 3 and the button 7. The button 7 is at least partially exposed on the bottom wall of the first housing 1. Pressing the button 7 activates the massager 10. The button 7 has a multi-level adjustment function. When the massager 10 needs to be activated, pressing the button 7 turns it on. Subsequently, the button 7 can be pressed at any time to adjust the massager 10's intensity level. The massager 10 also includes a battery compartment 13, which is installed in the receiving cavity 11 and spaced apart from the control component 6. The battery compartment 13 is electrically connected to the control component 6 and the drive motor 31, providing continuous power to the drive motor 31 so that the drive motor 31 can drive the massage head 22. It should be noted that the bottom wall of the first housing 1 is also provided with a charging port 9, which is spaced apart from the button 7. The charging port 9 is electrically connected to the battery compartment 13.
