Description

Technical Field

[0001] This invention relates to the field of leg massager technology, specifically to a leg meridian fatigue relief massager. Background Technology

[0002] Leg massage devices are widely used in various settings such as homes and offices because they can effectively relieve leg muscle soreness, unblock leg meridians, and eliminate limb fatigue. Currently, the mainstream leg massagers on the market are mainly divided into two categories: airbag massagers and traditional electric massagers.

[0003] Airbag-type leg massagers rely on the reciprocating motion of airbag inflation and deflation to achieve compression massage, and the overall structure of the device depends on the airbag's airtightness to achieve the massage function. However, airbags are mostly made of flexible plastic, which is prone to aging, damage, and air leakage after long-term repeated compression and bending. This not only significantly shortens the overall lifespan of the device, leading to loss of massage intensity and a substantial decrease in massage effect, but also makes disassembly and repair difficult and costly after the airbag is damaged. In most cases, the entire device must be replaced, resulting in poor practicality and economy. Traditional electric leg massagers mostly use a single-point fixed vibration or an independent motor to drive a single massage head structure. The single-point pressure is stiff and abrupt, which can easily cause squeezing and stinging pain. It can only briefly impact the surface muscles and is difficult to gently loosen the deep tense meridians. Summary of the Invention

[0004] The technical problem to be solved by this invention is that existing airbag massagers are prone to aging and air leakage, have short lifespans and high maintenance costs; traditional electric models mostly use single-point vibration or independent motors to drive a single massage head for massage, which is difficult to deeply soothe leg muscles and meridians and results in a poor therapeutic experience.

[0005] To solve the above problems, the technical solution adopted by the present invention is a fatigue relief massager for leg meridians, including an instrument shell, an arc-shaped groove surface on the top of the instrument shell, and a number of massage components located inside the instrument shell below the arc-shaped groove surface. The massage component includes a connecting frame with a drive space inside. A drive rod slides within the drive space, and a wave-shaped drive plate is located at the top of the drive rod. Several through holes are evenly distributed above the drive space inside the connecting frame. Limiting annular grooves are formed inside the through holes, and push rods pass through the through holes. A baffle is fixed to the side of the push rod in the limiting annular groove, and a compression spring is sandwiched between the baffle and the limiting annular groove. The bottom end of the push rod in the drive space has a rounded head structure to facilitate the pushing of the wave-shaped drive plate, and the bottom end of the push rod abuts against the upper side of the wave-shaped drive plate. Several telescopic rods are fixed near one end inside the instrument housing. The output end of the telescopic rod is connected and fixed to one end of the drive rod. The telescopic rods can drive the drive rod to move, so as to synchronously drive the wave-shaped drive plate to move. The movement of the wave-shaped drive plate causes its high and low points to reciprocate to contact the bottom end of the push rod, thereby driving the push rod to move up and down to massage the meridians and muscles of the legs.

[0006] As a further aspect of the present invention: limiting grooves are provided on both sides of the connecting frame, and several snap-fit ​​grooves that cooperate with the limiting grooves are provided on the arc-shaped groove surface, so as to facilitate the stable snap-fit ​​between the massage component and the instrument housing.

[0007] As a further aspect of the present invention: limit guide rails are provided on both sides of the driving space, and guide rail grooves that cooperate with the limit guide rails are provided on both sides of the driving rod, which can ensure the stable movement of the driving rod.

[0008] As a further aspect of the present invention: the compression spring is located above the baffle and always pushes the push rod downward, so that when the device is not in use and the bottom end of the push rod is at the lowest point of the wave-shaped drive plate, the push rod push-out distance is minimized.

[0009] As a further aspect of the present invention: when the bottom end of the push rod is located at the lowest point of the wave-shaped drive plate, it is also the lowest point of the push rod. When the wave-shaped drive plate moves, the low point of the push rod and the low point of the push rod will gradually move to the high point, thereby pushing the push rod to move upward.

[0010] As a further aspect of the present invention: a spherical massage head is fixed to the top of the push rod, and an elastic cloth is fixed to the upper side of the arc-shaped groove surface to facilitate fitting the user's legs. The elastic cloth wraps around the outside of several spherical massage heads.

[0011] As a further aspect of the present invention: support plates of different heights are fixed on the bottom surface of the instrument housing at the massage component, and a top plate supporting the massage component is fixed on the top of each support plate, which can effectively support the massage component so as to withstand the pressure of the legs.

[0012] As a further aspect of the present invention: a button is embedded on one side of the instrument housing to match several telescopic rods, so as to facilitate independent control of different telescopic rods; a charging port is provided at the other end of the instrument housing for charging the rechargeable battery pack; and a rechargeable battery pack is provided inside the instrument housing to provide power to several telescopic rods.

[0013] As a further aspect of the present invention, the length of the drive rod is less than the length of the drive space, which can provide sufficient space for the movement of the drive rod.

[0014] As a further aspect of the present invention, the stroke of the telescopic rod is equal to the distance between the high point and the low point of one cycle in the wave-shaped drive plate, which enables both the high point and the low point of the wave-shaped drive plate to contact the bottom end of the push rod.

[0015] The advantages of this invention compared to the prior art are: 1. This application abandons the traditional airbag massage structure and adopts a mechanically linked massage component to replace the flexible airbag structure, completely solving the problems of easy aging, damage, and air leakage of traditional airbags. The overall mechanical structure has strong stability, long service life, and no risk of failure due to airbag leakage; 2. This application adopts a combination structure of wave-shaped drive plate with multiple sets of push rods and spherical massage heads. The wave-shaped drive plate is driven to move back and forth by telescopic rods, which can drive multiple sets of massage heads to move up and down in a regular manner to provide multi-directional massage in order to relieve leg muscles.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The following description, in conjunction with the accompanying drawings, describes a leg meridian fatigue relief massager according to an embodiment of the present invention.

[0027] Combined with appendix Figure 5-8The device includes an instrument housing 1, approximately 40cm in length to accommodate the lower leg lengths of people of different heights. The top of the instrument housing 1 has an arc-shaped groove surface 11. Inside the instrument housing 1, below the corresponding arc-shaped groove surface 11, are several sets of massage components 2 for leg meridian and muscle massage. Each massage component 2 includes a connecting frame 21, with a drive space 22 extending through it. A drive rod 23, adapted to the internal structure of the drive space 22, slides within the drive space 22. A wave-shaped drive plate 24 is fixedly mounted at the top of the drive rod 23. The extension stroke of the telescopic rod 210 and the wave-shaped drive plate 24 should correspond to the horizontal distance between the peak and trough of a single wave cycle, ensuring... During the movement of the wave-shaped drive plate 24 with the drive rod 23, both the high and low points of the plate surface can stably contact and cooperate with the bottom round head structure of the push rod 27. The interior of the connecting frame 21 has several sets of vertically arranged through holes 25 evenly opened above the drive space 22. Each through hole 25 has a limiting ring groove 26 opened on its inner sidewall. The push rod 27, which can slide vertically along the interior of the through hole 25, is vertically inserted inside the through hole 25. A baffle 28 is fixedly installed on the sidewall of the push rod 27 at the corresponding position inside the limiting ring groove 26. A compression spring 29 is clamped between the baffle 28 and the upper side wall of the limiting ring groove 26. The compression spring 29 always maintains a downward pressure and continuously applies a downward pushing force to the baffle 28. Combined with appendix Figure 5 , 7 The bottom end of the push rod 27 inside the drive space 22 is designed with a rounded head structure. The bottom end face of the push rod 27 fits against the upper side plate of the wave-shaped drive plate 24. Several sets of telescopic rods 210 are fixedly installed inside the instrument housing 1 near the end position. The output end of the telescopic rod 210 is fixedly connected to the end of the corresponding drive rod 23 as an integral structure. Limit grooves 211 are opened on both the left and right side walls of the connecting frame 21. Several sets of limit grooves 211 are opened on the inner side of the arc-shaped groove surface 11 of the instrument housing 1. The slots 211 correspond one-to-one with the snap-fit ​​slots 12. The connecting frame 21 achieves stable assembly and fixation with the instrument housing 1 through the mutual snap-fit ​​cooperation between the limiting slots 211 and the snap-fit ​​slots 12. Limiting guide rails 212 are provided on the inner walls of both the left and right sides of the driving space 22. Guide rail grooves 213 that slide and adapt to the limiting guide rails 212 are provided on the side walls of both the left and right sides of the driving rod 23. The driving rod 23 achieves smooth linear sliding along the inside of the driving space 22 through the cooperation between the limiting guide rails 212 and the guide rail grooves 213. Combined with appendix Figure 1-5A spherical massage head 214 is fixedly mounted at the top of the push rod 27. An elastic cloth 13 is fixedly laid on the upper surface of the arc-shaped groove surface 11 of the instrument housing 1. The elastic cloth 13 completely covers the outer side of all the spherical massage heads 214 and can deform synchronously with the spherical massage heads 214 to fit the skin of the legs. Support plates 14 of different heights are fixedly installed on the bottom wall of the instrument housing 1 below each group of massage components 2. A top plate 15 is fixedly connected to the top end face of each support plate 14. The upper surface of the top plate 15 fits and supports the overall structure of the massage component 2 at the corresponding position. A control button 16 that matches and is compatible with each group of telescopic rods 210 is embedded on one side of the instrument housing 1. A charging port 17 is opened on the other side of the instrument housing 1. A rechargeable battery pack is integrated inside the instrument housing 1. The rechargeable battery pack is electrically connected to the charging port 17 and each group of telescopic rods 210. The overall length of the drive rod 23 is smaller than the internal length of the drive space 22.

[0028] The working principle of this application is as follows: During use, the leg meridian fatigue relief massager provides power to each telescopic rod 210 through the rechargeable battery pack inside the instrument housing 1. The user can independently control the start and stop of the corresponding telescopic rod 210 through the button 16 on the outside of the instrument housing 1. After the telescopic rod 210 is started, it can drive the drive rod 23 fixedly connected at the end to slide back and forth linearly along the drive space 22. The cooperation between the limit guide rail 212 and the guide rail groove 213 can ensure that the drive rod 23 moves smoothly without deviation. At the same time as the drive rod 23 moves, it simultaneously drives the wave-shaped drive plate 24 at the top to move horizontally back and forth. During the displacement of the wave-shaped drive plate 24, the high point and low point of its wave structure will alternately abut against the bottom round head structure of the push rod 27. When the low point of the wave-shaped drive plate 24 is... When the corresponding push rod 27 is at its bottom, the compression spring 29 releases its elastic force to press down the baffle 28, causing the push rod 27 to fall back to its lowest position. When the high point of the wave-shaped drive plate 24 gradually slides to the bottom of the push rod 27, the high point structure pushes the push rod 27 to overcome the elastic force of the compression spring 29 and lift it upward. In this way, the push rod 27 is cyclically and regularly moved up and down. The spherical massage head 214 at the top of the push rod 27 extends and retracts synchronously with the push rod 27 and performs continuous pressing and massage on the leg muscles and meridians placed on the arc-shaped groove surface 11 through the elastic cloth surface 13. At the same time, the support plate 14 and the top plate 15 inside the instrument housing 1 can provide stable support for the massage component 2 throughout the process, effectively bearing the leg pressing pressure, ensuring the overall stability of the equipment's operating structure, and achieving deep leg fatigue relief and meridian unblocking.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art, inspired by this description, design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
