Description

Technical Field

[0001] This utility model relates to the technical field of massage devices, and in particular to a massage apparatus. Background Technology

[0002] With economic development, people's pace of life and work is getting faster and faster, and the pressure is getting greater and greater. In order to complete the heavy work tasks every day, people have to sit in front of the computer for a long time. The hand holding the mouse will also maintain a fixed position for a long time, which leads to poor blood circulation, muscle stiffness and soreness, and thus easily causes hand diseases, affecting people's health.

[0003] To relieve hand discomfort, people usually use their other hand to manually knead and massage the affected arm, or use a simple massage hammer to tap or scrape the affected arm. This can only relieve discomfort to a certain extent, and manual kneading and tapping can increase people's burden and fatigue, resulting in a poor experience. Utility Model Content

Detailed Implementation

[0042] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0043] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] Please refer to Figures 1-4 The massage device 100 described in the first embodiment includes a power source 10; a transmission mechanism 20, which is connected to the power source 10; and a massage assembly 30, which includes a first massage body 31 and a second massage body 32. The first massage body 31 and the second massage body 32 are respectively connected to the transmission mechanism 20. Under the drive of the transmission mechanism 20, the first massage body 31 and the second massage body 32 can move closer to or further away from each other, and the first massage body 31 and the second massage body 32 cooperate to form a massage space.

[0046] Implementing the embodiments of this utility model will have the following beneficial effects:

[0047] The massage device 100 of this solution is applicable to automatically massaging body parts such as arms that experience discomfort due to poor blood flow or muscle stiffness, in order to relieve the user's arm discomfort. In use, the user inserts the arm to be massaged into the massage space formed by the first massage body 31 and the second massage body 32. Then, the power source 10 is turned on, and the power source 10 outputs driving force to the transmission mechanism 20, causing the transmission mechanism 20 to periodically move the first massage body 31 and the second massage body 32 closer to or further away from each other. This allows the first massage body 31 and the second massage body 32 to automatically create a kneading massage effect on the arm. Compared to existing technologies, the massage device of this solution can achieve automatic arm massage without increasing the user's burden or fatigue, and provides a better massage effect and user experience.

[0048] Please continue reading. Figure 2 In one embodiment, both the first massage body 31 and the second massage body 32 include a flexible body 50 and a support 60. The support 60 is connected to the flexible body 50 and slides in a guide rail assembly 26. The support 60 is generally made of a material with a certain degree of hardness and shape retention, such as rigid plastic or metal, and can act as the skeleton of the flexible body 50, providing support and positioning. For example, if the flexible body 50 is a ring, the support 60 will also be a ring structure.

[0049] The bracket 60 is used to connect to the guide rail assembly 26 so that the first massage body 31 and the second massage body 32 can reciprocate along the set path provided by the guide rail assembly 26 under the drive of the transmission mechanism 20, so as to realize the periodic approach or distance between the first massage body 31 and the second massage body 32.

[0050] The flexible body 50 can be made of flexible materials such as silicone to avoid excessive contact force that could cause discomfort or even pinching injury to the arm.

[0051] For example, the flexible body 50 can be a closed ring or a notched ring, and the support 60 is sleeved on the outside of the flexible body 50.

[0052] The gap between the first massage body 31 and the second massage body 32 forms a massage space. That is, the arm can be extended radially into the massage space between the first massage body 31 and the second massage body 32, and the side of the first massage body 31 facing the second massage body 32 and the side of the second massage body 32 facing the first massage body 31 exert a gentle pressure on the arm to achieve a massage effect.

[0053] Alternatively, the inner ring cavity of the first massage body 31, the gap between the first massage body 31 and the second massage body 32, and the inner ring cavity of the second massage body 32 together constitute the massage space. In use, the arm is inserted axially into the inner ring cavity of the first massage body 31, the gap between the first massage body 31 and the second massage body 32, and the inner ring cavity of the second massage body 32 in sequence. As the first massage body 31 and the second massage body 32 periodically move closer or further apart, the first massage body 31 and the second massage body 32 form a sliding kneading massage on the arm.

[0054] Alternatively, the first massage body includes a first flexible body and a first support connected to the first flexible body, and the second massage body includes a second flexible body and a second support connected to the second flexible body. The first flexible body is connected to the second flexible body through a connector to form an integral structure. The first flexible body, the connector, and the second flexible body work together to form a massage space.

[0055] The difference from the two embodiments described above is that the first flexible body is integrated with the second flexible body via a connector, while the first support and the second support are two independent components. When the first support and the second support move closer to or further away from each other, they will simultaneously pull and push the first and second flexible bodies to stretch and deform, thereby enabling a pinching massage to body parts such as the arm placed in the massage space.

[0056] In one embodiment, the massage device 100 further includes a housing 40, in which the power source 10, the transmission mechanism 20, and the massage component 30 are all mounted. The housing 40 integrates the power source 10, the transmission mechanism 20, and the massage component 30 into one unit. The massage device 100 has a compact structure, is lightweight, and is convenient and effortless to use, which helps to improve the user experience.

[0057] Please continue reading. Figure 2In the above embodiment, the power source 10 includes a control board 11, a battery 12, and a motor 13. The battery 12 is electrically connected to the control board 11, the control board 11 is electrically connected to the motor 13, and the motor 13 is drive-connected to the transmission mechanism 20. The control board 11 is used to receive input commands from the user, such as power on, power off, and speed adjustment. Then, the control board 11 outputs working commands to the motor 13, enabling the motor 13 to output driving force to the transmission mechanism 20 at a set speed, thereby controlling the first massage body 31 and the second massage body 32 to perform periodic massage on the arm at the required speed and pressure.

[0058] Battery 12 is used to power the entire device. Preferably, battery 12 is a rechargeable battery to improve the battery life and ease of use of the massage device 100.

[0059] Please continue reading. Figures 2 to 4 In the above embodiment, the transmission mechanism 20 includes a driving gear 21, a first driven gear 22, a second driven gear 23, a first eccentric rod 24, a second eccentric rod 25, and a guide rail assembly 26. The driving gear 21 is connected to the drive shaft of the motor 13. The first driven gear 22 and the second driven gear 23 both mesh with the driving gear 21 and are arranged on opposite radial sides of the driving gear 21. The first eccentric rod 24 is disposed on the first driven gear 22 and is slidably disposed in the first groove 311 of the first massage body 31. The second eccentric rod 25 is disposed on the second driven gear 23 and is slidably disposed in the second groove 321 of the second massage body 32. The first massage body 31 and the second massage body 32 are both slidably guided by the guide rail assembly 26.

[0060] Wherein, the length extension direction of the first slide groove 311 intersects the reciprocating sliding direction of the first massage body 31, and the length extension direction of the second slide groove 321 intersects the reciprocating sliding direction of the second massage body 32. For example, in this application, the length extension direction of the first slide groove 311 is perpendicular to the reciprocating sliding direction of the first massage body 31, and the length extension direction of the second slide groove 321 is perpendicular to the reciprocating sliding direction of the second massage body 32.

[0061] During use, motor 13 drives drive gear 21 to rotate, which in turn drives first driven gear 22 and second driven gear 23 to rotate synchronously. First driven gear 22 slides in first groove 311 with the aid of first eccentric rod 24. The first eccentric rod 24 applies a pushing or pulling force to the side wall of first groove 311, thereby moving first massage body 31. Similarly, second driven gear 23 slides in second groove 321 with the aid of second eccentric rod 25. The second eccentric rod 25 applies a pushing or pulling force to the side wall of second groove 321, thereby moving second massage body 32. The first massage body 31 and second massage body 32 move in opposite directions, thus enabling them to periodically move closer or further away from each other, creating a massage effect on the arm.

[0062] In the above embodiment, the guide rail assembly 26 includes at least one rail 261 and at least two guide sliders 262. At least one guide slider 262 is slidably fitted onto the rail 261 and connected to the first massage body 31, and at least one guide slider 262 is slidably fitted onto the rail 261 and connected to the second massage body 32. When the first eccentric rod 24 and the second eccentric rod 25 apply pushing or pulling forces to the first massage body 31 and the second massage body 32 respectively, the guide slider 262, through sliding engagement with the rail 261, provides guidance and limiting for the first massage body 31 and the second massage body 32, ensuring that the first massage body 31 and the second massage body 32 can only move in a straight line along the rail 261, moving closer or further away from each other, thus guaranteeing the stable movement of the first massage body 31 and the second massage body 32, and the structural reliability when clamping and massaging the arm.

[0063] Preferably, in this application, two tracks 261 are provided and arranged side by side at intervals. Each track 261 is provided with two guide sliders 262, and the two guide sliders 262 on each track 261 are respectively connected to the corresponding first massage body 31 and second massage body 32. This forms a situation where the first massage body 31 is simultaneously connected to the two guide sliders 262 on the two tracks 261 on both sides, and the second massage body 32 is simultaneously connected to the two guide sliders 262 on the two tracks 261 on both sides. This can form double-sided limiting and guiding for both the first massage body 31 and the second massage body 32, further improving the stability of the reciprocating movement of the first massage body 31 and the second massage body 32.

[0064] Please continue reading. Figure 5 and Figure 6 Furthermore, in the second embodiment of this application, the power source 10 includes a control board 11, a battery 12, a motor 13, a rotating disk 14, and a push-pull rod 15. The battery 12 is electrically connected to the control board 11, the control board 11 is electrically connected to the motor 13, the drive shaft of the motor 13 is connected to the rotating disk 14, and the eccentric shaft 14a provided on the rotating disk 14 is slidably nested with the strip hole 15a of the push-pull rod 15.

[0065] The transmission mechanism 20 includes a first movable block 27, a transmission gear 28, a second movable block 29, and a guide rail assembly 26. One end of the first movable block 27 is connected to one end of the push-pull rod 15, and the other end of the first movable block 27 is slidably disposed in the second slide groove 321 of the second massage body 32. The first movable block 27 is provided with a first rack 271, which meshes with the transmission gear 28. The second movable block 29 is provided with a second rack 291, which meshes with the transmission gear 28. One end of the second movable block 29 is slidably disposed in the first slide groove 311 of the first massage body 31. Both the first massage body 31 and the second massage body 32 are slidably guided by the guide rail assembly 26.

[0066] The difference from the first embodiment is that this embodiment uses the push-pull motion of the push-pull rod 15, and in conjunction with the meshing transmission of the first rack 271, the transmission gear 28 and the second rack 291, the first movable block 27 and the second movable block 29 respectively synchronously push the second massage body 32 and the first massage body 31 closer or further apart, so as to achieve the effect of the first massage body 31 and the second massage body 32 massaging the arm located in the massage space.

[0067] Please continue reading. Figure 7 and Figure 8 Furthermore, in the third embodiment of this application, the power source 10 includes a control board 11, a battery 12, a motor 13, and a gear set 16. The battery 12 is electrically connected to the control board 11, the control board 11 is electrically connected to the motor 13, the drive shaft of the motor 13 is connected to the gear set 16, and the transmission mechanism 20 includes a transmission rod 29a. The transmission rod 29a is provided with a gear part 291a and a threaded part 292a. The gear part 291a meshes with the gear set 16.

[0068] The transmission mechanism 20 also includes a first movable block 27, a transmission gear 28, a second movable block 29, and a guide rail assembly 26. The first movable block 27 is provided with a threaded sleeve 272 and a first rack 271. The threaded sleeve 272 is screwed onto the outside of the threaded portion 292a. The first rack 271 meshes with the transmission gear 28. One end of the first movable block 27 is slidably disposed in the second slide groove 321 of the second massage body 32. The second movable block 29 is provided with a second rack 291, which meshes with the transmission gear 28. One end of the second movable block 29 is slidably inserted into the first slide groove 311 of the first massage body 31. Both the first massage body 31 and the second massage body 32 are slidably guided by the guide rail assembly 26.

[0069] The difference from the first and second embodiments described above is that the rotational power output by the motor 13 is first transmitted to the gear set 16. After the gear set 16 reduces the speed and increases the torque, it is transmitted to the transmission rod 29a. The transmission rod 29a can be driven to rotate by the gear part 291a. During the rotation of the transmission rod 29a, the threaded part 292a and the threaded sleeve 272 form a threaded transmission, thereby driving the first movable block 27 to push or pull the second massage body 32 along the guide rail assembly 26. At the same time, by means of the meshing transmission of the first rack 271, the transmission gear 28 and the second rack 291, the second movable block 29 and the first movable block 27 form a synchronous movement in opposite directions, so that the second movable block 29 pushes or pulls the first massage body 31 and the second massage body 32 closer or further apart, realizing the periodic massage of the arm.

[0070] Please continue reading. Figure 9 In addition, this application also provides a fourth embodiment, in which the power source 10 includes a battery 12, a control board 11, a motor 13 and a gear set 16. The battery 12 is electrically connected to the control board 11, the control board 11 is electrically connected to the motor 13, and the drive shaft of the motor 13 is connected to the gear set 16 for transmission.

[0071] The transmission mechanism 20 includes a transmission rod 29a, a first movable block 27, a second movable block 29, and a guide rail assembly 26. The transmission rod 29a is provided with a gear portion 291a, a first threaded portion 293a, and a second threaded portion 294a. The threads of the first threaded portion 293a and the second threaded portion 294a have opposite directions of rotation. The gear portion 291a, the first threaded portion 293a, and the second threaded portion 294a are arranged at intervals along the axial direction of the transmission rod 29a. The gear portion 291a meshes with the gear set 16. One end of the first movable block 27 is provided with a first threaded sleeve. 273, the first threaded sleeve 273 is screwed onto the outside of the first threaded portion 293a, and the other end of the first movable block 27 is slidably disposed in the first groove 311 of the first massage body 31; one end of the second movable block 29 is provided with a second threaded sleeve 295, the second threaded sleeve 295 is screwed onto the outside of the second threaded portion 294a, and the other end of the second movable block 29 is slidably disposed in the second groove 321 of the second massage body 32; both the first massage body 31 and the second massage body 32 are slidably guided with the guide rail assembly 26.

[0072] The difference between the fourth embodiment and the third embodiment is that the transmission rod 29a is provided with a first threaded portion 293a and a second threaded portion 294a, and the threads of the first threaded portion 293a and the second threaded portion 294a have opposite directions of rotation. In this way, when the transmission rod 29a rotates clockwise or counterclockwise, the first threaded portion 293a and the second threaded portion 294a can simultaneously apply opposing or opposing transmission forces to the first threaded sleeve 273 and the second threaded sleeve 295. This allows the first movable block 27 and the second movable block 29 to simultaneously pull the first massage body 31 and the second massage body 32 closer to each other or further away from each other, thereby achieving periodic massage of the arm. This embodiment uses fewer parts and has higher structural reliability.

[0073] Please continue reading. Figure 10 Furthermore, this application also provides a fifth embodiment, in which the power source 10 includes a battery 12, a control board 11, a first motor 13a, a second motor 13b, a first gear set 16a, and a second gear set 16b. The battery 12 is electrically connected to the control board 11, and the control board 11 is electrically connected to the first motor 13a and the second motor 13b. The drive shaft of the first motor 13a is connected to the first gear set 16a, and the drive shaft of the second motor 13b is connected to the second gear set 16b.

[0074] The transmission mechanism 20 includes a first transmission rod 295a, a second transmission rod 296a, a first movable block 27, a second movable block 29, and a guide rail assembly 26. The first transmission rod 295a has a first gear portion 291a and a first threaded portion 293a. The first gear portion 291a meshes with the first gear set 16a. One end of the first movable block 27 has a first threaded sleeve 273, which is screwed onto the outside of the first threaded portion 293a. The other end of the first movable block 27 is slidably disposed on the first massage body 31. Within the first groove 311, the second transmission rod 296a is provided with a second gear portion 291a and a second threaded portion 294a. The second gear portion 291a meshes with the second gear portion 294a. One end of the second movable block 29 is provided with a second threaded sleeve 295, which is screwed onto the outside of the second threaded portion 294a. The other end of the second movable block 29 is slidably disposed within the second groove 321 of the second massage body 32. Both the first massage body 31 and the second massage body 32 are slidably guided by the guide rail assembly 26.

[0075] The working principle is basically the same as that of the fourth embodiment described above. Both are driven by the motor 13, gear set 16 and threaded transmission pair to move the first massage body 31 and the second massage body 32 closer to or further away from each other. The only difference is that the first massage body 31 is driven by the first motor 13a, the first gear set 16a, the first transmission rod 295a and the first movable block 27, while the second massage body 32 is driven by the second motor 13b, the second gear set 16b, the second transmission rod 296a and the second movable block 29. This structural design can at least ensure that when one motor 13 fails, the other motor 13 can still drive the corresponding massage body to move independently, and can still ensure that the first massage body 31 and the second massage body 32 move closer to or further away from each other, thus ensuring the massage effect and normal operation of the massage device 100.

[0076] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
