Description

Technical Field

[0001] This invention relates to the field of massage equipment, specifically to an infrared mounting structure for a knee massager and the massager itself. Background Technology

[0002] In daily life, knees need to bend and straighten frequently, especially during exercise. Therefore, it's important to massage the knee joint to help it relax and repair. Furthermore, in cold and damp seasons, knees are more susceptible to various knee joint diseases, such as rheumatism and arthritis. Therefore, we need to take extra care of our knees, using massage or warming devices to protect them.

[0003] Publication No. CN109303982B discloses an infrared mounting structure for a knee massager, including an inner shell, a light-transmitting sheet bracket, and a light plate. The light-transmitting sheet guides and scatters light, making the infrared radiation distribution within the inner shell more uniform and comprehensive, thus increasing the infrared massage area and ensuring the comprehensiveness and comfort of the massage. However, this device cannot be adjusted for users of different body types. If the inner cavity of the device is too large or too deep relative to the user, it can easily cause the device to shake during use.

[0023] Example 1

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, the massager includes: a shell 1, side panels 2, a mounting base 3, a light-transmitting sheet 4, an infrared lamp panel 5, and a slot 7. The shell 1 has a fan-shaped cross-section with a right-angled central angle. Its internal space is for the user's knee joint. Several stops are installed on the side of the curved surface inside, providing a limiting effect during use, ensuring the user's knee can only reach the stop position at its deepest point. Two straps 100 are installed on the two right-angled sides of the shell 1. These straps 100 can wrap around the user's thighs and calves during use. Connecting buckles 101 are installed on the straps 100. The connecting buckles 101 are made of tearable nylon, a common feature, and will not be described in detail. During use, the connecting buckles 101 securely connect the straps 100 to the thighs and calves, ensuring the shell 1 is stably aligned with the knee joint. The side panels 2 are installed at the top of the shell 1, and their inner space communicates with the inner cavity of the shell 1. Several card holders 3 are continuously arranged along the arc direction within the side plate 2. Several light-transmitting sheets 4 are installed within several card holders 3. The light-transmitting sheets 4 are existing devices; in this embodiment, optical-grade acrylic is used as an example, but it is not limited to this material, and other materials that meet the requirements can be used. After the light is guided and scattered by the light-transmitting sheets 4, the distribution of infrared rays on the inner circumference of the inner and outer shell 1 is more uniform and comprehensive, which is beneficial to increasing the infrared light massage area and ensuring the comprehensiveness and comfort of the massage. There are two slots 7, which are installed on both sides of the inner wall of the side plate 2. The infrared lamp plate 5 is installed inside the side plate 2, relative to the top of the card holder 3, and the infrared lamp plate 5 is engaged with the slot 7. The infrared lamp plate 5 is an existing device that can emit near-infrared light suitable for physiotherapy. In this embodiment, the RS PRO 796-0079 model is used as an example, but it is not limited to this model, and any model that meets the requirements can be used. A top plate 6 is installed on the outer side of the side plate 2. The top plate 6 is used to cover the infrared lamp plate 5, etc., to ensure a relatively stable working environment. The top plate 6 is made of plastic, which has a certain degree of elasticity and can deform and recover within a small range. Several protrusions 9 are installed on both sides of the side plate 2, and several through slots 8 are opened on both sides of the top plate 6. The through slots 8 and the protrusions 9 are engaged. The cooperation between the two can ensure a stable connection between the top plate 6 and the side plate 2. Within the elastic range, the top plate 6 can be pried open so that the through slots 8 can be disengaged from the protrusions 9, thus enabling the top plate 6 to be disassembled.

[0025] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the massager also includes: a pressure airbag 10, an air inlet pipe 11, a one-way valve 12, an air outlet pipe 13, and an expansion airbag 19. The pressure airbag 10 is installed at the bottom of the outer shell 1. The pressure airbag 10 has a spindle-shaped hollow structure with internal gas storage space. The air inlet pipe 11 is installed at one end of the pressure airbag 10, and the one-way valve 12 is installed at the free end of the air inlet pipe 11. The one-way valve 12 is an existing device that ensures air can only flow into the pressure airbag 10 through the one-way valve 12. The air outlet pipe 13 is installed at the other end of the pressure airbag 10, and the expansion airbag 19 is installed on the inner wall of the outer shell 1 and connected to the air outlet pipe 13. Both the pressure airbag 10 and the expansion airbag 19 are made of elastic material. In this embodiment, the device uses TPU (thermoplastic polyurethane elastomer) material, which can deform under pressure and automatically recover its shape after the external force is removed. During use, the user's knee joint is located inside the outer shell 1, and the inner side of the knee joint corresponds to the position of the pressure airbag 10. When the leg is bent, the pressure airbag 10 is driven by the user's knee joint movement, causing it to deform under pressure and transfer gas to the expansion airbag 19. This expansion airbag 19 inflates, achieving a stable connection between the user's knee joint and the outer shell 1, preventing excessive gaps between the inner wall of the outer shell 1 and the user's knee, and avoiding device wobbling. A connector 17 is installed on the side of the outer shell 1, and the connector 17 is connected to the expansion airbag 19. The free end of the air outlet pipe 13 forms a tip 16, which is connected to the connector 17 via a flexible hose 18. The pressure airbag 10 is detachable and connected via the flexible hose 18, preventing the gas passage from being blocked or broken. C-shaped clips 21 and ball grooves 14 are installed on both sides of the bottom of the outer shell 1. The C-shaped clips 21 are made of elastic metal, and external pressure can engage the air inlet pipe 11 with the C-shaped clips 21, achieving a fixed connection. The ball groove 14 is made of elastic metal, and its outer wall has a groove for the air outlet pipe 13 to pass through. A retaining ball 15 is installed on the air outlet pipe 13, and the retaining ball 15 is rotatably engaged with the ball groove 14. In use, the retaining ball 15 is first pressed into the ball groove 14, leaving space between the end of the pressure bladder 10 away from the ball groove 14 and the outer shell 1. In this state, the air outlet pipe 13 is located in the reserved groove to avoid interference. After the user's knee is placed in the outer shell 1, the retaining ball 15 is rotated to make the air inlet pipe 11 engage with the C-shaped buckle 21, completing the installation of the pressure bladder 10. Then, the user bends their knee, causing the pressure bladder 10 to compress, and the expansion bladder 19 begins to inflate, thus ensuring a stable placement of the knee and the outer shell 1.

[0026] Furthermore, there are an even number of expansion airbags 19, evenly divided into two groups. The two groups of expansion airbags 19 are respectively installed on both sides of the inner wall of the outer casing 1. Multiple expansion airbags 19 are connected sequentially via connecting pipes 20. The volume of the pressure airbag 10 is matched to the total volume of the multiple expansion airbags 19, ensuring that a single thorough compression of the pressure airbag 10 can fully inflate all expansion airbags 19, maximizing the limiting effect. During use, the limiting degree can be flexibly adjusted by adaptively compressing the pressure airbag 10 according to the user's physical condition. When venting, removing the hose 18 allows the expansion airbags 19 to be vented. Simultaneously, the distribution of multiple expansion airbags 19 further enhances the limiting effect. Also, refer to... Figure 3 The inner wall of the outer shell 1 is symmetrically provided with clearance grooves 22, and the connecting pipe 20 between the expansion airbags 19 on the left and right sides is inserted into the clearance grooves 22 to avoid interference between the connecting pipe 20.

[0027] Example 2

[0028] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the difference between this embodiment and embodiment 1 is that it also includes: a rotating rod 23, a supporting rod 24, a first torsion spring 25, a connecting rod 26, and a locking mechanism.

[0029] There are several rotating rods 23, arranged in pairs. Each pair of rotating rods 23 is equidistant from each other along a circumferential axis and rotatably mounted inside the outer casing 1. Several support rods 24 are installed between the two support rods 24 in each pair, forming a single integrated structure. The outer wall of each support rod 24 has a rubber layer. During use, the support rod 24 restricts the user's knee position. The elastic rubber layer contacts the skin at the knee joint, preventing rigid contact damage. A first torsion spring 25 is installed between the axis of rotation of the rotating rod 23 and the outer casing 1. When the rotating rod 23 is subjected to external force and rotates, the first torsion spring 25 deforms. After the external force is removed, the elastic force of the first torsion spring 25 allows the rotating rod 23 to reverse and return to its original position. A connecting rod 26 rotatably connects each pair of rotating rods 23. (See reference...) Figure 10 The two adjacent linkage rods 26 are alternately arranged to avoid interference. Simultaneously, the linkage rods 26 work together to allow each set of rotating rods 23 to rotate synchronously and at the same angle. In actual use, due to the different body shapes of different users, the rotation of each set of rotating rods 23 can adjust the position of the support rod 24, limiting the position of the user's knee joint and preventing the internal space of the outer casing 1 from becoming too deep or large, which could cause the device to shake. The outer casing 1 is equipped with a locking mechanism that can lock the rotating rods 23, thus fixing the positions of the rotating rods 23 and the support rod 24.

[0030] like Figure 11 and Figure 12As shown, the locking mechanism includes: a control wheel 27, a locking groove 28, a rotating arm 29, a rotating rod 30, a second torsion spring 31, a locking arm 32, and a fixing rod 33. The control wheel 27 is rotatably mounted in the housing 1 and connected to the rotating shaft of one of the rotating rods 23. Several locking grooves 28 are equidistantly spaced around the circumference of the control wheel 27. The rotating arm 29 is rotatably mounted inside the housing 1. The rotating rod 30 is mounted on the rotating arm 29 and extends out of the housing 1. The second torsion spring 31 is installed between the rotating rod 30 and the housing 1. Rotating the rotating rod 30 causes the rotating arm 29 to rotate and deforms the second torsion spring 31. Removing the external force allows the rotating rod 30 and the rotating arm 29 to reverse and reset using the elastic force of the second torsion spring 31. The end of the rotating arm 29 furthest from the rotating rod 30 forms the locking arm 32, which engages with the locking groove 28. When the rotating arm 29 stops rotating, it brakes the control wheel 27, preventing it from rotating on its own. The fixing rod 33 is mounted on the housing 1 and corresponds to the position of the rotating arm 29. The fixing rod 33 can limit the rotation range of the rotating arm 29.

[0031] The actual working principle of the above structure is as follows: In the initial state, the rotating rod 23 is at its highest position, and the support rod 24 is at its position closest to the top of the inner cavity of the outer shell 1. When it is necessary to change the depth of the inner space of the outer shell 1, pull down any one of the support rods 24, and the rotating rod 23 will rotate synchronously, thereby driving the control wheel 27 to rotate. With the cooperation of the locking groove 28, the rotating arm 29 will rotate counterclockwise accordingly, causing the locking arm 32 to disengage from the original locking groove 28 (see reference). Figure 11 and Figure 12 When the locking arm 32 aligns with the next locking slot 28, the spring force of the second torsion spring 31 can reset the rotating arm 29, causing the locking arm 32 to engage in the corresponding locking slot 28, thus locking the control wheel 27. At this time, the spring force of the first torsion spring 25 causes the rotating rod 23 to rotate counterclockwise to reset (see reference). Figure 11 (direction), and when the user's knee joint enters the outer shell 1, it will cause the support rod 24 and the rotating rod 23 to also have a tendency to return to their original position. At this moment, the rotating arm 29 cannot continue to rotate clockwise due to the limiting effect of the fixed rod 33. Figure 12 The direction of rotation prevents the control wheel 27 and the rotating rod 23 from reversing, thus effectively fixing the support rod 24. When a reset is required, manually rotate the rotating rod 30 counterclockwise to make the rotating arm 29 rotate synchronously, causing the locking arm 32 to disengage from the locking groove 28, thereby resetting the control wheel 27 and the rotating rod 23.

[0032] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
