Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a hand massager. Background Technology

[0002] Hand massage plays an important role in promoting blood circulation and relieving fatigue. However, most existing hand massage devices have relatively simple structures and limited massage functions, making it difficult to provide a comprehensive and effective massage to multiple areas such as the palms and fingers simultaneously. Some massagers only offer simple pressing or vibration massage to the palms, and their massage of the fingers is not detailed enough, failing to meet the diverse hand massage needs of different users. Furthermore, existing massagers suffer from complex transmission structures and inflexible adjustment of massage intensity and methods, resulting in unsatisfactory massage effects. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, this utility model discloses a hand massager that can provide all-round and multi-level massage to the hands, effectively relieving hand fatigue and improving hand health.

[0004] A hand massager includes a base 10, a palm massage roller 30, and a sliding seat 40;

[0005] A support shaft 11 is provided on the upper surface of the base 10, and the palm massage wheel 30 is rotatably mounted on the base 10 via the support shaft 11;

[0006] The base 10 is provided with a guide rail 13, and the sliding seat 40 is movably mounted on the base 10 via the guide rail 13;

[0007] The palm massage roller 30 is connected to the sliding seat 40 through a linkage device, and the sliding seat 40 is driven to perform reciprocating linear motion while the palm massage roller 30 rotates.

[0008] Furthermore, the palm massage wheel 30 includes an outer ring gear 31 and an inner ring gear 32, which are arranged coaxially and are driven by the motor drive mechanism 20 to perform rotational motion.

[0009] Furthermore, the motor drive mechanism 20 is installed below the base 10, and the motor drive mechanism 20 includes a lower gear 23, an upper gear 24, and a transition gear 25;

[0010] The upper gear 24 meshes with the outer ring gear 31, and the lower gear 23 meshes with the inner ring gear 32 through the transition gear 25, thereby realizing the opposite rotation of the outer ring gear 31 and the inner ring gear 32.

[0011] Furthermore, the linkage device includes a connecting rod seat 41, a connecting rod 42, and a rotating joint. The connecting rod seat 41 is disposed on the hub of the inner ring gear 32. The connecting rod seat 41 is connected to the connecting rod 42 through the rotating joint, and the connecting rod 42 is connected to the sliding seat 40 through the rotating joint.

[0012] Furthermore, the support shaft 11 has a through hole 12 extending along the axis at its center, and the outer ring gear 31 is rotatably mounted on the support shaft 11; the inner ring gear 32 has an inner shaft at its center, which can pass upward through the through hole 12 and extend to the upper surface of the outer ring gear 31, and the upper part of the inner shaft is fixedly connected to the center of the massage tray 34, forming a layered rotating structure to realize reverse massage of the inner and outer rings of the palm.

[0013] Furthermore, several sets of massage devices are installed on the upper end face of the outer ring gear 31 and the upper end face of the massage tray 34. The massage device includes a massage ball seat 33 and a massage ball 35 installed in the massage ball seat 33. A central ball seat 36 is installed in the center of the massage tray 34, and a magnetic massage ball is installed on the central ball seat 36 to achieve full coverage massage of the palm.

[0014] Furthermore, a four-finger massage unit 50 and a thumb massage unit 60 are mounted on the sliding seat 40, and follow the sliding seat 40 to perform reciprocating linear motion.

[0015] Furthermore, the four-finger massage unit 50 includes a four-finger wheel seat 51 and several sets of massage rollers 52, and multiple sets of airbags 53 are provided on the top of the four-finger wheel seat 51.

[0016] Furthermore, the thumb massage unit 60 includes two sets of massage steel ball arrays, which are symmetrically arranged on both sides of the palm massage wheel 30.

[0017] Furthermore, a back-of-hand massage airbag 70 is provided above the palm massage roller 30 corresponding to the back of the hand;

[0018] A wrist massage airbag is provided at the rear of the palm massage roller 30 corresponding to the wrist.

[0019] The palm massage roller 30 is provided with a heating groove below it, which can hold aromatherapy tablets;

[0020] The massage device is provided with a housing 80 on its outer layer.

[0021] The beneficial technical effects of this utility model through the above technical solutions are as follows:

[0022] 1. This utility model utilizes an integrated transmission structure. When the inner gear 32 rotates, it drives the sliding seat 40 to reciprocate along the guide rail 13 of the base 10 via the connecting rod 42. This, in turn, drives the massage rollers 52 of the four-finger massage unit 50 to clamp and stretch the fingers, forming a transmission structure that uses only a single motor 21 to drive the palm and finger massage components. While ensuring a comprehensive massage effect, this reduces the number of massage drive mechanisms, greatly simplifies the transmission process, and lowers manufacturing costs.

[0023] 2. The palm massage wheel 30 disclosed in this utility model uses a transmission meshing method that drives the inner ring gear 32 and the outer ring gear 31 to rotate in opposite directions. When they rotate in opposite directions, the inner and outer ring massage components of the palm massage wheel 30 form a reverse motion trajectory. This reverse motion trajectory creates a counterforce at the junction of the inner and outer rings of the palm. This counterforce can deeply stimulate the palm fascia, muscles and acupoints, and penetrates deeper into the tissues more easily than rotation in one direction, thus relieving hand fatigue.

[0024] 3. The palm massage structure primarily employs rolling massage and airbag pressure to reduce friction between the massage surface and the palm skin, preventing damage. Furthermore, the included magnetic massage balls deeply stimulate acupoints in the palm through magnetic field action, achieving a dual therapeutic effect of "physical pressure + magnetic therapy" combined with rotational motion, enhancing blood circulation and relieving fatigue.

[0025] 4. The symmetrical array of massage steel balls in the thumb massage unit 60 reciprocates with the sliding seat 40. The point contact characteristics of the steel balls can precisely stimulate the thumb joint and surrounding acupoints. The symmetrical distribution design is compatible with both left and right hands, requiring no additional structural adjustments. Compared with traditional fixed-position massage heads, it can adapt to the thumb placement of different hand shapes, improving the versatility of the device. Moreover, the steel ball material is wear-resistant and easy to clean, ensuring stable performance over long-term use.

[0026] 5. The four-finger massage unit 50 uses the inflation and deflation of airbags 53 for compression massage, allowing for individual pressure adjustment for each finger. The gentle compression of the airbags 53, combined with the rolling massage of the massage rollers 52, not only mimics the kneading sensation of a human hand but also allows for precise control of massage intensity through air pressure. This adapts to the different finger sizes and pressure preferences of various users, overcoming the shortcomings of traditional airbag massage such as "large contact area and non-adjustable pressure," thus improving the comfort and targeted nature of finger massage.

[0027] 6. The housing 80 serves as both the inlet and outlet of the semi-enclosed cavity, balancing ease of use with structural protection. The opening design of the housing 80 allows users to quickly place or remove their hands, and the curved edges are ergonomically designed to prevent skin abrasions. Furthermore, the housing 80 effectively protects internal precision components such as gears and airbags from dust and liquid intrusion, extending the equipment's lifespan, while also providing rigid support for the overall structure.

[0028] 7. The heating slot below the base 10 is compatible with heating element components. It adopts an embedded design and can be used with consumables such as mugwort tablets and essential oils. It releases effective ingredients through directional heating, which is safe, controllable, and easy to replace. It combines the advantages of traditional moxibustion and modern physiotherapy.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Please see the appendix Figure 1-8 This utility model discloses a hand massager, including a base 10, a motor drive mechanism 20, a palm massage wheel 30, a sliding seat 40, a four-finger massage unit 50, a thumb massage unit 60, a back-of-hand massage airbag 70, and a shell 80.

[0040] In an optional embodiment, the motor drive mechanism 20 and the palm massage wheel 30 are mounted on the base 10; the motor drive mechanism 20 is connected to the palm massage wheel 30 and provides rotational power to the palm massage wheel 30; the sliding seat 40 is fixedly mounted on the base 10 and can slide along the guide rail 13.

[0041] Furthermore, a linkage device is provided on the hub of the inner ring gear 32. This linkage device uses a connecting rod seat 41, which connects to the sliding seat 40 via a connecting rod 42, driving the sliding seat 40 to perform reciprocating linear motion. The four-finger massage unit 50 and the thumb massage unit 60 are mounted on the sliding seat 40 and move accordingly. The back-of-hand massage airbag 70 is fixedly mounted on the upper part of the palm massage wheel 30 and connected to the base 10. After assembly, the four-finger massage unit 50 extends between the back-of-hand massage airbag 70 and the palm massage wheel 30, covering the thumb massage unit 60, forming a cavity that can accommodate the entire palm. An outer shell 80 encloses the internal structure. Through this structure, this utility model provides a hand massager with a complete structure and comprehensive functions.

[0042] Specifically, a motor 21 is fixedly installed below the base 10. The motor 21 outputs power to the lower gear 23 and the upper gear 24 through a reduction gearbox 22, and provides torque through a bushing connection. The upper gear 24 meshes with the outer ring gear 31; the lower gear 23 meshes with the transition gear 25, indirectly meshing with the inner ring gear 32, thereby providing rotational power to the various massage components of the palm massage wheel 30. The transition gear 25 is mounted on the base 10. Through this transmission structure, the inner ring gear 32 moves in opposite directions to the outer ring gear 31, enabling a thorough and effective massage of the inner and outer sides of the palm. In addition, each transmission gear adopts a human-shaped gear structure, ensuring smooth and efficient transmission.

[0043] Specifically, a circular tray 14 is provided on the base 10 for mounting and supporting the palm massage roller 30, and a support shaft 11 is provided at the center of the tray, with a through hole 12 extending along the axis at the center of the shaft.

[0044] Specifically, the outer ring gear 31 is mounted on the circular tray 14 and fitted around the outside of the support shaft 11, allowing it to rotate freely. The center hole of the inner ring gear 32 is coaxial with the support shaft 11. An inner shaft is positioned above the center of the inner ring gear 32, passing upwards through the through hole 12 of the support shaft 11 and fixedly connected to the massage tray 34 positioned above the outer ring gear 31, providing support for it. Thus, the rotation of the inner ring gear 32 is transmitted to the massage tray 34 via the inner shaft, causing them to move coaxially and synchronously. Simultaneously, the outer ring gear 31 can rotate independently around the support shaft 11, forming a layered coaxial transmission structure. This transmission method creates a coaxial gear train, preventing interference between the inner and outer massage rings during operation, thereby achieving reverse massage.

[0045] Specifically, the upper surface of the outer ring gear 31 is provided with six sets of massage ball seats 33, arranged at equal intervals around the gear axis. A massage ball 35 is installed above each massage ball seat 33, allowing for massage of the acupoints on the outer ring of the palm during operation. The inner ring gear 32 transmits torque to the massage tray 34 via its inner shaft. Six sets of massage ball seats 33 are arranged at equal intervals around the axis of the massage tray 34 above it. A massage ball 35 is installed above each seat, allowing for massage of the acupoints on the inner ring of the palm during operation. When installed, the rolling axis of all massage ball seats 33 and massage balls 35 always points towards the axis of the palm massage wheel 30. This structure avoids relative friction between the palm and the massage balls 35 during massage, thus protecting the palm skin and improving massage quality. Furthermore, a central ball seat 36 is provided at the center of the massage tray 34, on which a magnetic massage ball 35 can be installed, allowing for massage of the acupoints in the center of the palm during operation. Through the above implementation method, the palm massage roller 30 can fully cover the acupoints in the outer circle, inner circle and center of the palm and massage them thoroughly, thereby achieving a good massage effect.

[0046] Specifically, a connecting rod seat 41 is fixedly provided at a suitable point between the inner ring gear 32 and its teeth. A connecting rod 42 is installed on the connecting rod seat 41, and an end cap is provided below the connecting rod seat 41 to fix the connecting rod 42. The other end of the connecting rod 42 is connected to the sliding seat 40 through a rotating joint.

[0047] Specifically, the bottom of the sliding seat 40 is equipped with a slider, and the two middle sliders are equipped with rollers, which are connected to the base 10 via the guide rail 13. The inner ring gear 32 rotates, driving the sliding seat 40 to reciprocate linearly along the guide rail 13 via the connecting rod 42, thus forming a crank-slider mechanism that can be used to provide power for finger stretching and massage. The guide rail 13 can be used by direct sliding or rolling, alone or in combination.

[0048] Specifically, the four-finger massage unit 50 aims to massage the entire index finger to the little finger, primarily through the squeezing and stretching massage of the massage rollers 52. A four-finger wheel seat 51 is mounted on the sliding seat 40, and eight sets of massage rollers 52, rotatable around the mounting axis, are fixedly mounted below the four-finger wheel seat 51 for massaging the front of the fingers. A pressing mechanism is provided above the four-finger wheel seat, mainly consisting of four airbags 53, with two swing frames 54 below each airbag 53. The swing frames 54 can swing flexibly around a fixed axis connected to an end bushing. A rotatable massage roller 52 is located below each swing frame 54, enabling pressing and stretching massage of the back of the fingers. The airbags 53 have openings at their upper ends for connecting air valves for inflation and deflation. The four sets of finger airbags 53 are mounted above the four-finger wheel seat 51 by screws and move synchronously with the sliding seat 40; the air valves are small and can be installed in the empty space below the sliding seat 40. During operation, the air valves can control the inflation and deflation of air. By adjusting the air pressure of each airbag 53, when the airbag 53 is inflated, the swing frame 54 is squeezed and rotated downwards, independently controlling the pressure between each finger and the massage roller 52. This allows the massage rollers 52 at both ends to clamp each finger with appropriate force, and then perform a stretching massage operation.

[0049] Specifically, the four-finger massage unit 50 has an attached massage mechanism at the finger insertion opening, which can be used in conjunction with massage rollers 52 and massage balls. It can be flexibly applied according to the length, thickness and other conditions of the fingers to achieve a more thorough massage effect.

[0050] Specifically, symmetrically distributed thumb massage units 60 are arranged at both ends of the palm massage roller 30. These units mainly consist of two arrays of massage steel balls, with several massage steel balls mounted on corresponding ball holders. The ball holders are fixed to the sliding seat 40 and can follow the sliding seat 40 to perform reciprocating linear motion, thereby providing a massage effect on the entire thumb. By employing a symmetrical massage structure, the thumb massage units 60 can provide a good massage effect for both the left and right hands.

[0051] Specifically, an arched back-of-hand massage airbag 70 is installed above the palm massage roller 30, fully covering the back of the hand area. The back-of-hand massage airbag 70 is fixedly mounted on the base 10. After inflation and deflation, it can press downwards onto the back of the hand. The pressure between the palm and the palm massage roller 30 below can be controlled by adjusting the air pressure of the back-of-hand massage airbag 70. A semi-enclosed cavity is formed between the back-of-hand massage airbag 70 and the palm massage roller 30, providing a comprehensive, all-around massage for the palm and back of the hand. A housing 80 is provided outside the base 10 and the back-of-hand massage airbag 70 to support and protect the internal structure.

[0052] The palm massage roller 30 is provided with a back-of-hand massage airbag 70 above it, which together with the base 10 forms a semi-enclosed cavity;

[0053] An open housing 80 is provided on the outer layer of the massage device. The opening of the housing 80 is the inlet and outlet of the semi-closed cavity. A wrist massage airbag is provided at the inlet of the semi-closed cavity. The wrist massage airbag is fixedly installed on the base 10 and is in contact with the inner surface of the opening at the rear end of the housing 80.

[0054] Specifically, the wrist massage airbag is located at the entrance of the palm massage area, fixedly installed on the base 10, and connected to the inner surface of the rear opening of the housing 80. The wrist massage airbag adopts a ring-shaped structure. When the massage system is not turned on, the palm can pass through the wrist massage airbag and penetrate into each massage area. When the massage system is turned on, the wrist massage airbag is inflated and deflated to achieve a massage effect on the wrist area, and can also prevent the massage device provided by this utility model from accidentally falling off the hand.

[0055] Specifically, a heating groove is provided below the base 10, which can fit or be embedded inside the base 10. Consumables such as mugwort tablets can be placed inside, and the heating module inside can heat the consumables after placement. This function integrates practical functions such as moxibustion, achieving the effects of warming the hands, dispelling cold, and unblocking meridians.

[0056] Specifically, both the back-of-hand massage airbag 70 and the wrist massage airbag are equipped with heaters on their surfaces, which can heat the gas inside the airbags, thereby achieving the heat therapy function for the massage areas of the back of the hand and the wrist.

[0057] In addition, such as Figure 8 As shown, a closed cam 90 or other transmission methods can be used to convert rotation into reciprocating linear motion.

[0058] When the product is in operation, the user places their left or right palm down into the massage cavity from the end of the base 10. The palm massage roller 30 below the palm rotates in the opposite direction, fully massaging the acupoints on the palm. At the same time, the back-of-hand massage airbag 70 periodically inflates and deflates, pressing the acupoints on the back of the hand. When the index, middle, ring, and little fingers are inserted into the four-finger wheel seat 51, the clamping mechanism, in conjunction with the massage roller 52, clamps the fingers and follows the lower sliding seat 40 to perform linear reciprocating motion, achieving a stretching massage of the fingers. The massage effect can be flexibly controlled according to the control program. The massage steel ball of the thumb massage unit 60 can achieve rolling massage of the thumb. The heating module in the heating groove at the bottom of the base 10 can heat the placed mugwort tablets and other consumables to achieve the moxibustion function. The heater installed on the surface of the back-of-hand massage airbag 70 and the wrist massage airbag heats the gas in the airbag, thereby achieving the heat therapy function. Through the above components, this utility model provides comprehensive massage and health care functions for various areas of the palm, including palm massage, four-finger stretching and finger side massage, thumb front massage, back of hand pressing massage, and hot compress function.

[0059] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
