Description

Technical Field

[0001] This invention relates to the field of massager technology, and in particular to a foot massage mechanism with adjustable height. Background Technology

[0002] In the prior art, the patent with patent number "202220453983.4" is entitled "A Foot Massager Core and Massage Device". It can realize the pressing massage of the sole of the foot through the airbag device. However, the massage component corresponding to the sole of the foot cannot rotate, which has limitations.

[0003] In the prior art, patent number 201820397699.3, entitled "A Foot Massager," includes a frame. The bottom of the frame is equipped with massage components and a drive mechanism for driving the massage components. The massage components include a sole massage mechanism, an arch massage mechanism, and a heel massage mechanism, arranged side-by-side. The sole massage mechanism includes two identical first massage rollers and a first rotating shaft passing through them. The arch massage mechanism includes two identical second massage rollers and a second rotating shaft passing through them. The heel massage mechanism includes two identical third massage rollers and a third rotating shaft passing through them. The second rotating shaft is connected to the first and third rotating shafts respectively. Each of the first, second, and third massage rollers has massage protrusions. Massage is achieved through these protrusions when the second massage rollers rotate; however, the second massage rollers cannot rise or fall, thus failing to achieve the upward pressure action on the arch of the foot.

[0004] Both types of massage devices have limitations, and their direct combination affects the rotation of the second massage wheel. Therefore, there is an urgent need for a foot massage device that can both rotate the massage bumps for massage and drive the second massage wheel to rise and fall for pressure. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides a foot massage mechanism with adjustable height. By mounting a second rotating shaft on a swing arm, the second rotating shaft can be raised independently to perform a pressing action without affecting its normal rotation. Its structure is simple, its layout is reasonable, and its practicality is stronger.

[0006] This invention discloses a foot massage mechanism with adjustable height, comprising a frame, a foot massage assembly mounted on the frame, and a massage drive for driving the foot massage assembly. The foot massage assembly includes a first massage assembly, a second massage assembly, and a third massage assembly. The first massage assembly includes a first massage wheel and a first rotating shaft for driving the first massage wheel to rotate. The second massage assembly includes a second massage wheel and a second rotating shaft for driving the second massage wheel to rotate. The third massage assembly includes a third massage wheel and a third rotating shaft for driving the third massage wheel to rotate. The mechanism is characterized in that the first and third rotating shafts are rotatably mounted on the frame, and a swing seat is rotatably mounted on the third rotating shaft. The second rotating shaft is rotatably mounted on the swing seat. The frame is provided with a push block and a push drive for driving the push block to slide. The swing seat has a contact surface, and the push block has an inclined pressing surface for pressing the contact surface to cause the swing seat to swing. The inclined pressing surface pressing the contact surface can drive the second rotating shaft upward through the swing seat.

[0007] Using the above technical solution, when in use, the massage drive can drive the first, second, and third rotating shafts to rotate, thereby enabling the massage rollers to massage the soles of the feet. When a foot-pressing massage is needed, the push drive can drive the push block to slide. At this time, the inclined pressing surface on the push block presses against the contact surface, thereby causing the swing seat to swing along an arc, further driving the second rotating shaft to rise. Then, the second massage rollers press on the soles of the feet, thus achieving the function of pressing massage. Furthermore, the second rotating shaft is controlled independently by the swing of a single swing seat, which does not affect its normal rotational massage and can still achieve the function of pressing massage. Its structure is simple and its layout is relatively reasonable.

[0008] A further feature of the present invention is that the massage drive is a motor mounted on the swing base, and the second rotating shaft is linked to the output end of the massage drive. The second rotating shaft can drive the first rotating shaft and the third rotating shaft to rotate synchronously via a pulley group or a sprocket group. The end of the frame corresponding to the first rotating shaft is provided with a waist-shaped hole. The first rotating shaft rotates and slides on the waist-shaped hole. The first rotating shaft is provided with a limiting arm, one end of which is hinged to the first rotating shaft and the other end of which is hinged to the second rotating shaft.

[0009] Using the above technical solution, the swing seat facilitates the installation of massage drive components. A single motor can simultaneously drive the first, second, and third rotating shafts, reducing manufacturing costs and simplifying the internal structure. Furthermore, by designing a waist-shaped hole, when the push block pushes the swing seat, the second rotating shaft, via a limiting arm, can pull the first rotating shaft to move horizontally. This limits the increase in the distance between the second and first rotating shafts and accommodates the angle change of the limiting arm when the second rotating shaft is raised. This allows the swing seat to swing and raise the second rotating shaft, enabling the massage protrusions to press against the soles of the feet. The waist-shaped hole also limits the sliding displacement of the first rotating shaft, restricting the raising angle of the second rotating shaft and making it more stable during use. Moreover, the use of a sprocket or pulley system for transmission ensures that raising or lowering does not affect the transmission coordination of the first, second, and third rotating shafts, resulting in enhanced stability.

[0010] A further feature of the present invention includes a displacement detection device for detecting the sliding displacement of the push block.

[0011] By adopting the above technical solution, the sliding displacement of the jacking block can be detected, thereby further controlling or detecting the lifting range of the second rotating shaft.

[0012] A further feature of the present invention is that the second massage wheel is provided with a plurality of massage protrusions arranged along the circumferential direction, and the second rotating shaft is also provided with a high point detection device for detecting the position of the massage protrusions. The high point detection device includes a rotating component on the second rotating shaft and a rotating sensor on the swing base. The rotating component rotates synchronously with the second rotating shaft, and the receiving end of the rotating sensor is correspondingly arranged with the rotating component.

[0013] Using the above technical solution, the massage protrusions change position when the second massage wheel rotates, making it difficult to detect their orientation, which leads to defects when pressing. By using the high point detection device, the orientation of the massage protrusions can be easily adjusted to be upward, making the pressing effect better. Furthermore, by having the rotating component rotate together with the second rotating shaft, the position of the massage protrusions can be further controlled and understood.

[0014] A further feature of the present invention is that a sliding frame is guided and slidable on the frame, the push drive includes a motor fixedly mounted on the frame, a screw that is rotatably mounted on the frame and linked with the push drive is provided, a screw sleeve adapted to the screw is provided on the sliding frame, the push block is mounted on the sliding frame and slides synchronously with it, and the displacement detection device includes a trigger and a sensor, one of which is mounted on the sliding frame and the other on the frame.

[0015] Using the above technical solution, when the push drive drives the screw to rotate, the sliding frame cannot rotate because it is guided by the sliding. Then, the sliding frame can be moved as a whole through the screw sleeve. When the sliding frame slides, the position of one of the sensing element and the trigger element will change, and then a corresponding signal can be sent to understand the current position of the sliding frame, thereby understanding the position of the push block, and further understanding the position of the second massage wheel height adjustment.

[0016] A further feature of the present invention is that the contact surface on the swing base is an arc-shaped contact surface, and is located at the middle position of the second rotation axis.

[0017] The above technical solution is adopted to prevent the second rotating shaft from shifting when it is raised, making it more stable during use. Attached Figure Description

Implementation

[0029] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0030] In the description of this invention, it should be understood that the terms "upper," "lower," "bottom," "top," "front," "rear," "inner," "outer," "left," and "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. The driving component in this article is preferably a motor, but it can also be an electric cylinder or a pneumatic cylinder. The specific installation method is common knowledge to those skilled in the art. In this article, one of the first massage component and the third massage component is a foot massage component and the other is a heel massage component, and the second massage component is a sole massage component.

[0031] This invention discloses a foot massage mechanism with adjustable height, including a frame 1, a foot massage assembly 2 mounted on the frame 1, and a massage drive 3 for driving the foot massage assembly 2. The foot massage assembly 2 includes a first massage assembly 21, a second massage assembly 22, and a third massage assembly 23. The first massage assembly 21 includes a first massage wheel 211 and a first rotating shaft 212 for driving the first massage wheel 211 to rotate. The second massage assembly 22 includes a second massage wheel 221 and a second rotating shaft 222 for driving the second massage wheel 221 to rotate. The third massage assembly 23 includes a first massage wheel 211, a second massage assembly 22, and a third massage assembly 23. In this embodiment of the invention, the first rotating shaft 212 and the third rotating shaft 232 are both rotatably mounted on the frame 1. The frame 1 also includes a swing seat 6 rotatably mounted on the third rotating shaft 232. The second rotating shaft 222 is rotatably mounted on the swing seat 6. The frame 1 is provided with a push block 51 and a push drive member 52 for driving the push block 51 to slide. The swing seat 6 is provided with an abutment surface 61. The push block 51 is provided with an inclined pressing surface 511 for pressing the abutment surface 61 to make the swing seat 6 swing.

[0032] Using the above technical solution, when in use, the massage drive 3 can drive the first rotating shaft 212, the second rotating shaft 222 and the third rotating shaft 232 to rotate, thereby realizing the massage roller to massage the sole of the foot. When the sole of the foot needs to be pressed, the push drive 52 can drive the push block 51 to slide. At this time, the inclined pressing surface 511 on the push block 51 presses against the contact surface 61, thereby driving the swing seat 6 to swing in an arc, further driving the second rotating shaft 222 to rise. Then, the second massage roller 221 presses on the sole of the foot to realize the function of pressing massage. Moreover, the second rotating shaft 222 is controlled by the swing of the swing seat 6 alone, which does not affect its normal rotation massage, and can realize the function of pressing massage. Its structure is simple and the layout is relatively reasonable.

[0033] The massage drive 3 is a motor mounted on the swing base 6. The second rotating shaft 222 is linked to the output end of the massage drive 3 (preferably, the massage drive 3 is a motor, in which case a reduction gear set drives the second rotating shaft 222 to rotate). The second rotating shaft 222 can drive the first rotating shaft 212 and the third rotating shaft 232 to rotate synchronously via the pulley set 40 or the sprocket set. The frame 1 has a waist-shaped hole 50 at the end corresponding to the first rotating shaft 212. The first rotating shaft 212 rotates and slides on the waist-shaped hole 50. The first rotating shaft 212 is provided with a limiting arm 4, one end of which is hinged to the first rotating shaft 212 and the other end is hinged to the second rotating shaft 222. The swing base 6 facilitates the installation of the massage drive 3. One motor can drive the first rotating shaft 212, the second rotating shaft 222 and the third rotating shaft 232 to rotate simultaneously, which can reduce manufacturing costs and simplify the internal structure. Furthermore, by setting the waist-shaped hole 50, the first rotating shaft 212, the second rotating shaft 222 and the third rotating shaft 232 can be rotated simultaneously. When the push block 51 pushes the swing seat 6, the second rotating shaft 222 can pull the first rotating shaft 212 to move through the limiting arm 4, thereby limiting the increase of the distance between the second rotating shaft 222 and the first rotating shaft 212 (when the second rotating shaft 222 descends, the first rotating shaft 212 can be pushed back to its original position through the limiting arm 4, limiting the distance between the two to decrease). It also adapts to the angle change of the limiting arm 4 when the second rotating shaft 222 is raised, so that the swing seat 6 can swing to raise the second rotating shaft 222, so that the massage protrusion 2211 can press against the sole of the foot. The waist-shaped hole 50 limits the sliding displacement of the first rotating shaft 212, thereby limiting the angle of the second rotating shaft 222's raising, making it more stable during use. Furthermore, the use of a sprocket group or belt pulley group 40 for transmission means that raising or lowering does not affect the transmission coordination of the first rotating shaft 212, the second rotating shaft 222, and the third rotating shaft 232, resulting in stronger stability.

[0034] It also includes a displacement detection device 7 for detecting the sliding displacement of the push block 51, which can detect the sliding displacement of the push block 51, thereby further controlling or detecting the lifting range of the second rotating shaft 222.

[0035] The second massage roller 221 is provided with a plurality of massage protrusions 2211 arranged in a circumferential direction. The second rotating shaft 222 is also provided with a high point detection device 8 for detecting the position of the massage protrusions 2211. The high point detection device 8 includes a rotating component 81 on the second rotating shaft 222 and a rotating sensor 82 on the swing base 6. (The rotating component 81 is preferably a turntable, and the rotating sensor 82 is an infrared sensor. The turntable is provided with protrusions or notches. When the protrusions or notches correspond to the infrared sensor, the massage protrusions are facing upwards. The specific alignment method is well known to those skilled in the art.) The rotating component 81 rotates synchronously with the second rotating shaft 222. The receiving end of the rotating sensor 82 is correspondingly set with the rotating component 81. Because the massage protrusion 2211 will change position when the second massage wheel 221 rotates, it is not easy to detect its orientation position, which makes it defective when pressing. By using the high point detection device 8, the orientation of the massage protrusion 2211 can be easily adjusted to be set upward, so that it has a better effect when pressing. Furthermore, by rotating the rotating component 81 together with the second rotating shaft 222, it is easier to control and understand the position of the massage protrusion 2211.

[0036] A sliding frame 9 is guided and slidable on the frame 1. The push drive component 52 includes a motor fixedly mounted on the frame 1. A screw 10, which is linked and cooperates with the push drive component 52, is rotatably mounted on the frame 1 (the push drive component 52 preferably drives the screw 10 to rotate through a worm gear, but it can also drive the screw to rotate through two helical gears). A threaded sleeve 20 adapted to the screw 10 is provided on the sliding frame 9. The push block 51 is mounted on the sliding frame 9 and slides synchronously with it. The displacement detection device 7 includes a trigger component 72 and a sensing component 71 (the sensing component 71 can be a sensor, such as a visual sensor or an infrared sensor, which can be purchased directly from the market). The trigger 72 can be a trigger plate, trigger block, or trigger bar, which can be moved relative to the trigger by the sensing element. One of the trigger 72 and the sensing element 71 is located on the sliding frame 9, and the other is located on the frame 1. When the push drive 52 drives the screw 10 to rotate, the sliding frame 9 cannot rotate because it is guided to slide. Then, the sliding frame 9 can be moved as a whole through the screw sleeve 20. When the sliding frame 9 slides, the position of one of the sensing element 71 and the trigger 72 will change, and then a corresponding signal can be sent to understand the current position of the sliding frame 9, thereby understanding the position of the push block 51, and further understanding the position of the height adjustment of the second massage wheel 221.

[0037] The contact surface 61 on the swing base 6 is an arc-shaped contact surface and is located in the middle of the second rotating shaft 222 to prevent the second rotating shaft 222 from shifting when it is raised, making it more stable during use.
