Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically to an electric hand massager. Background Technology

[0002] With the fast pace of modern life, physical therapy based on traditional Chinese medicine meridian theory to improve muscle fatigue, chronic pain and sub-health issues has gradually gained attention. Traditional hand massage is mainly achieved through manual pressing or manual operation of rollers. However, due to the fast pace of life, traditional manual massage is difficult to meet user needs because it is time-consuming and requires a fixed location.

[0003] Existing electric massage devices mostly use fixed rollers or vibration modules, which can only achieve single-point massage or large-area stimulation. They cannot perform directional, layered, continuous massage and pressing on acupoint sequences of multiple meridians, and lack path design that is deeply integrated with traditional Chinese medicine theory, which reduces the user experience and massage effect. This utility model proposes a new solution to the above problems. Utility Model Content

[0004] To overcome at least one of the aforementioned drawbacks, this utility model provides an electric hand massager. The objective of this utility model can be achieved by adopting the following technical solution:

[0005] This application provides a hand electric massager, comprising:

[0006] The outer shell includes a cylindrical body with an opening for a hand to enter, and a finger limiting mechanism is provided inside the outer shell to limit the hand.

[0007] A mold mechanism is disposed within the cylinder. The mold mechanism includes a palm mold assembly and a back-of-hand mold assembly disposed opposite to each other, and a receiving cavity for accommodating a hand is formed between the palm mold assembly and the back-of-hand mold assembly.

[0008] A massage component is movably connected to a mold mechanism. The massage component includes at least six massage units. Three massage units are located in the palm direction and move from the fingers toward the arm along the trajectories of the Lung Meridian of Hand-Taiyin, Pericardium Meridian of Hand-Jueyin, and Heart Meridian of Hand-Shaoyin, respectively, and stop and press at several preset acupoints in sequence. The other three massage units are located in the back of the hand and move from the arm toward the fingers along the trajectories of the Large Intestine Meridian of Hand-Yangming, Triple Energizer Meridian of Hand-Shaoyang, and Small Intestine Meridian of Hand-Taiyang, respectively, and stop and press at several preset acupoints in sequence.

[0009] In one possible implementation, the palm mold assembly includes a palm mold with a palm mold groove adapted to the shape of the palm. The palm mold assembly also includes a first guide rail, a second guide rail, and a third guide rail. The first guide rail extends along the direction of the Lung Meridian of Hand-Taiyin, the second guide rail extends along the direction of the Pericardium Meridian of Hand-Jueyin, and the third guide rail extends along the direction of the Heart Meridian of Hand-Shaoyin.

[0010] The back-of-the-hand mold assembly includes a back-of-the-hand mold with a back-of-the-hand mold groove adapted to the shape of the back of the hand. The back-of-the-hand mold assembly also includes a fourth guide slide rail, a fifth guide slide rail, and a sixth guide slide rail. The fourth guide slide rail extends along the direction of the Hand Yangming Large Intestine Meridian, the fifth guide slide rail extends along the direction of the Hand Shaoyang Sanjiao Meridian, and the sixth guide slide rail extends along the direction of the Hand Taiyang Small Intestine Meridian.

[0011] In one possible implementation, a portion of the massage components is located within the mold mechanism, while another portion of the massage components passes through the mold mechanism for contact with the hand;

[0012] The massage assembly includes a first massage unit, a second massage unit, a third massage unit, a fourth massage unit, a fifth massage unit, and a sixth massage unit. The first massage unit moves along the first guide rail from the fingers to the arm, the second massage unit moves along the second guide rail from the fingers to the arm, the third massage unit moves along the third guide rail from the fingers to the arm, the fourth massage unit moves along the fourth guide rail from the arm to the fingers, the fifth massage unit moves along the fifth guide rail from the arm to the fingers, and the sixth massage unit moves along the sixth guide rail from the arm to the fingers.

[0013] In one possible implementation, the electric hand massager includes a processor and a voice receiver and / or operation buttons. The processor is used to receive operation signals from the voice receiver and / or operation buttons and correspondingly activate at least one massage unit of the massage assembly.

[0014] The massage unit includes a drive assembly and a pressing assembly connected to each other. The drive assembly is located within the mold mechanism, and at least a portion of the pressing assembly can pass through the mold mechanism to contact the hand. The drive assembly drives the pressing assembly to move along a preset trajectory.

[0015] In one possible implementation, the driving assembly includes a first slider, a drive motor, a lead screw, and a spring telescopic rod. The drive motor is poweredly connected to the lead screw, and the first slider is threadedly connected to the lead screw. The drive motor drives the lead screw to rotate, causing the first slider to slide along a preset trajectory. The first slider is connected to the pressing assembly through the spring telescopic rod, so that the pressing assembly can move to conform to the palm mold groove or the back of the hand mold groove.

[0016] In one possible implementation, the pressing assembly includes a second slider, an electric telescopic rod, a compression spring, and a pressing contact. The first slider is connected to the second slider via the spring telescopic rod. The second slider is provided with the electric telescopic rod. The palm-shaped groove or the back-of-the-hand groove is elastically connected to the pressing contact via the compression spring. The compression spring applies a spring force to the pressing contact to move the pressing contact away from the hand. The output end of the electric telescopic rod is connected to the pressing contact so that the pressing contact can move towards the hand.

[0017] In one embodiment, the pressing contact includes a connecting portion and an end portion. The diameter of the connecting portion is larger than the diameter of the end portion. A transition portion is provided between the connecting portion and the end portion. A portion of the connecting portion is located within the mold mechanism. The guide rail includes a groove. The width of the groove is smaller than the diameter of the connecting portion and larger than the diameter of the end portion. The groove has a plurality of holes corresponding to acupoints. The inner diameter of the holes is larger than the diameter of the connecting portion, so that when the massage unit moves to a preset acupoint, the pressing contact can move towards the hand to stop and press the acupoint on the hand.

[0018] In one possible implementation, the preset acupoints include:

[0019] The points on the Lung Meridian of Hand-Taiyin are Kongzui, Lieque, Taiyuan, Yuji, and Shaoshang.

[0020] The points on the Hand Jueyin Pericardium Meridian are Ximen, Neiguan, Daling, Laogong, and Zhongchong.

[0024] The points on the Hand-Taiyang Small Intestine Meridian are Shaoze, Qiangu, Houxi, Wangu, Yanggu, Yanglao, and Zhizheng.

[0025] In one embodiment, the electric hand massager further includes a wrapping part, which includes an airbag, a fan, and an electric heating wire. The airbag is disposed inside the cylinder, and the cylinder has ventilation holes. The fan and the electric heating wire are disposed inside the cylinder and correspond to the ventilation holes. The fan is used to send air from outside the outer shell into the cylinder through the ventilation holes. The air is heated by the electric heating wire to form hot air that fills the airbag, so that the airbag is inflated to wrap around and fix the hand.

[0026] In one possible implementation, the finger limiting mechanism includes a first limiting member, a second limiting member, a third limiting member, and a fourth limiting member arranged sequentially from top to bottom. The first limiting member is used to form a barrier between the thumb and the index finger, the second limiting member is used to form a barrier between the index finger and the middle finger, the third limiting member is used to form a barrier between the middle finger and the ring finger, and the fourth limiting member is used to form a barrier between the ring finger and the little finger.

[0027] The limiting component includes an upper partition, a lower partition, and a connecting rod. The upper partition is used to contact the fingers located on the upper side, and the lower partition is used to contact the fingers located on the upper side. The upper partition and the lower partition are connected to the outer shell or the mold mechanism through the connecting rod.

[0028] The beneficial technical effects of this utility model are as follows: According to the present disclosure, the electric hand massager includes a shell, a mold mechanism, and a massage component. The mold mechanism can adapt to different hand shapes, and the finger limiting mechanism separates the fingers to prevent hand position deviation. The mold mechanism is provided with a guide rail that matches the direction of meridians in traditional Chinese medicine. The massage component includes at least six massage units. The massage units move in a specific direction and cover key acupoints to achieve directional stimulation of meridians and key acupoints. The massage units dynamically adjust the pressure intensity to ensure that the hands can obtain a stable and uniform massage experience without manual intervention, meeting the conditioning needs of users with different physical conditions. This breaks through the technical bottleneck of the single function of traditional hand massage devices and improves the massage experience and portability. Attached Figure Description

[0048] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to enable those skilled in the art to understand and clarify the technical solution of this utility model more clearly, the embodiments described below are not limited thereto. The present utility model will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0049] In this utility model, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "install," "connect," "join," and "fix" should be interpreted broadly. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "join" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", 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 utility model and simplifying the description, and do not indicate or imply that the device or unit 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 utility model.

[0051] This application provides a hand electric massager, such as... Figures 1-11As shown, the device includes a housing 1, a mold mechanism 2, and a massage component 5. The housing 1 includes a cylindrical body 11 with an opening 12 for the hand to enter. A finger limiting mechanism 3 is provided inside the housing 1 to limit the hand. The mold mechanism 2 is disposed inside the cylindrical body 11 and includes a palm mold component 21 and a back-of-hand mold component 22 arranged opposite to each other, forming a receiving cavity for accommodating the hand. The massage component 5 is movably connected to the mold mechanism 2 and includes at least six massage units. Three massage units are located in the palm direction and move from the fingers to the arm along the trajectories of the Lung Meridian of Hand-Taiyin, Pericardium Meridian of Hand-Jueyin, and Heart Meridian of Hand-Shaoyin, respectively, and stop and press at several preset acupoints in sequence. The other three massage units are located in the back-of-hand direction and move from the arm to the fingers along the trajectories of the Large Intestine Meridian of Hand-Yangming, Triple Energizer Meridian of Hand-Shaoyang, and Small Intestine Meridian of Hand-Taiyang, respectively, and stop and press at several preset acupoints in sequence.

[0052] The electric hand massager provided in this embodiment has an opening 12 in the cylindrical body 11 of the outer shell 1 that allows the palm and forearm to naturally extend into it. The finger limiting mechanism 3 inside separates the fingers through multiple limiting members to ensure that the hand is stably placed in the receiving cavity. The palm mold assembly 21 and the back mold assembly 22 are respectively provided with ergonomically adapted palm mold grooves 212 and back mold grooves 222, which can adapt to different hand shapes. Its guide rail system extends strictly along the six hand meridians. Among them, the three guide rails on the palm side are set along the direction of the Lung Meridian of Hand-Taiyin, Pericardium Meridian of Hand-Jueyin, and Heart Meridian of Hand-Shaoyin, and the three guide rails on the back side are set along the direction of the Large Intestine Meridian of Hand-Yangming, Triple Energizer Meridian of Hand-Shaoyang, and Small Intestine Meridian of Hand-Taiyang. The six massage units are respectively embedded in the corresponding guide rails. The three massage units in the palm direction move from the fingers to the arm, simulating the traditional Chinese medicine meridian-tonifying method. The three massage units on the back of the hand move in opposite directions, simulating the reverse meridian purging method. The movement speed of each massage unit is controlled by the drive component 511 and the movement path is limited by the guide rail. The pressing component 512 realizes the movement and pressing of the pressing contact 5124 through the electric telescopic rod 5122 and the compression spring 5123. When the massage unit moves to the preset acupoint along the guide rail, the pressing contact 5124 passes through the hole on the slide groove and accurately touches the acupoint with elastic pressure. After pausing to press, it continues to move along the track. The massage unit moves in a specific direction and covers key acupoints, realizing the directional stimulation of meridians and key acupoints. The massage unit dynamically adjusts the pressing pressure to ensure that the hand can obtain a stable and uniform massage experience without manual intervention, meeting the conditioning needs of users with different constitutions. It breaks through the technical bottleneck of the single function of traditional hand massage devices and improves the massage experience and portability.

[0053] Among them, such as Figure 1 and Figure 2As shown, the outer casing 1 may also include a cover plate 13, which can limit the elbow. The battery can be embedded in the cover plate 13. After the hand is aligned, the cover plate 13 is closed, and the battery is powered on.

[0054] Alternatively, the battery can be directly embedded in the cylinder 11 without the need for a cover plate 13.

[0055] It is understandable that, such as Figure 1 As shown, feet can be provided at the bottom of the cylinder 11. The contact surface of the feet forms rolling resistance through geometric constraints, which inhibits the movement of the cylinder 11 and avoids the risk of misalignment between the pressing contact 5124 and the acupoints of the human body due to accidental displacement.

[0056] It is understandable that, such as Figure 9 As shown, the bottom of the cylinder 11 can be set as a flat surface, and the flat surface can also be provided with anti-slip texture or anti-slip pad. By optimizing the surface roughness of the flat surface, friction is increased, the movement of the cylinder 11 is suppressed, and the risk of misalignment between the pressing contact 5124 and the human acupoint caused by accidental displacement is avoided.

[0057] In one possible implementation, such as Figure 1 and Figure 2 As shown, the palm mold assembly 21 includes a palm mold 211, as... Figures 4-6 As shown, the palm mold 211 has a palm mold groove 212 adapted to the shape of the palm. The palm mold assembly 21 also includes a first guide rail 213, a second guide rail 214, and a third guide rail 215. The first guide rail 213 extends along the direction of the Lung Meridian of Hand-Taiyin, the second guide rail 214 extends along the direction of the Pericardium Meridian of Hand-Jueyin, and the third guide rail 215 extends along the direction of the Heart Meridian of Hand-Shaoyin. Figure 7 and Figure 8 As shown, the back of the hand mold assembly 22 includes a back of the hand mold 221, on which a back of the hand mold groove 222 adapted to the shape of the back of the hand is provided. The back of the hand mold assembly 22 also includes a fourth guide slide rail 223, a fifth guide slide rail 224 and a sixth guide slide rail 225. The fourth guide slide rail 223 extends along the direction of the Hand Yangming Large Intestine Meridian, the fifth guide slide rail 224 extends along the direction of the Hand Shaoyang Sanjiao Meridian, and the sixth guide slide rail 225 extends along the direction of the Hand Taiyang Small Intestine Meridian.

[0058] The palm groove 212 and back-of-hand groove 222 are designed based on the characteristics of the human hand. The curvature of the groove matches the natural curvature of the palm and back of the hand, ensuring that the distance between the groove and the skin surface is similar after the hand is placed in the groove. The palm groove 212 is equipped with three guide rails, namely the first guide rail 213, the second guide rail 214, and the third guide rail 215, which extend along the directions of the Lung Meridian of Hand-Taiyin, the Pericardium Meridian of Hand-Jueyin, and the Heart Meridian of Hand-Shaoyin, respectively. The back-of-hand groove 222 is equipped with three guide rails, namely the fourth guide rail 223, the fifth guide rail 224, and the sixth guide rail 225, which extend along the directions of the Large Intestine Meridian of Hand-Yangming, the Triple Energizer Meridian of Hand-Shaoyang, and the Small Intestine Meridian of Hand-Taiyang, respectively. This solves the problem of missed acupoints or ambiguous positioning caused by trajectory deviations in manual operation rollers or traditional massage devices, and significantly improves the accuracy of meridian stimulation.

[0059] Understandably, the extension direction of the guide rail coincides with the meridian path, covering the main acupoint area from the base of the fingers to the forearm. The trajectory of the guide rail is consistent with the curved surface of the mold groove, ensuring that the massage unit always stays close to the skin surface of the hand when it moves.

[0060] In one possible implementation, such as Figure 9 As shown, one part of the massage component 5 is located inside the mold mechanism 2, and the other part of the massage component 5 passes through the mold mechanism 2 for contact with the hand.

[0061] The massage component 5 located inside the mold mechanism 2 is embedded in the linear slide rail of the mold mechanism 2 and moves in a directional manner through the linear slide rail connection. The massage component 5 located outside the mold mechanism 2 extends out through the slide groove and hole and comes into contact with the hand. The embedded drive component 511 reduces the overall size of the device, while the exposed pressing contact 5124 extends out in a directional manner through the slide groove and hole, which not only ensures the effective execution of the massage function, but also avoids the redundancy of the external structure, making the device more in line with the ergonomic grip requirements.

[0062] Furthermore, such as Figure 9 As shown, the massage component 5 includes a first massage unit 51, a second massage unit 52, a third massage unit 53, a fourth massage unit 54, a fifth massage unit 55, and a sixth massage unit 56, as follows: Figure 5 As shown, the first massage unit 51 moves along the first guide rail 213 from the fingers to the arm, the second massage unit 52 moves along the second guide rail 214 from the fingers to the arm, and the third massage unit 53 moves along the third guide rail 215 from the fingers to the arm. Figure 7 As shown, the fourth massage unit 54 moves from the arm to the fingers along the fourth guide rail 223, the fifth massage unit 55 moves from the arm to the fingers along the fifth guide rail 224, and the sixth massage unit 56 moves from the arm to the fingers along the sixth guide rail 225.

[0063] Among them, the first massage unit 51, the second massage unit 52 and the third massage unit 53 in the palm direction push and press along the three Yin meridians of the hand (Taiyin Lung Meridian, Jueyin Pericardium Meridian, Shaoyin Heart Meridian) to simulate "tonification" and promote the replenishment of Qi and blood; the fourth massage unit 54, the fifth massage unit 55 and the sixth massage unit 56 in the back of the hand direction drain along the three Yang meridians of the hand (Yangming Large Intestine Meridian, Shaoyang Triple Energizer Meridian, Taiyang Small Intestine Meridian) to simulate "drainage" and clear meridian blockage. The bidirectional movement forms a synergistic effect of tonification and drainage, and at the same time achieves the dual therapeutic goals of regulating Qi and blood and excreting metabolic waste.

[0064] Understandably, the shape of each guide rail corresponds to a specific meridian pathway, allowing the massage unit to sequentially reach key acupoints along that meridian as it moves along the track. The forward and reverse movement directions match the therapeutic characteristics of Yin and Yang meridians, ensuring that the stimulation sequence of acupoints along each meridian conforms to Traditional Chinese Medicine massage theory, avoiding omissions or incorrect order. The massage units moving in opposite directions towards the palm and back of the hand create an alternating pressure rhythm, preventing local muscle fatigue caused by continuous pressure in one direction. Simultaneously, the mechanical stimulation generated by bidirectional movement activates different muscle groups, enhancing the synergistic effect of blood circulation and nerve reflexes in the hand.

[0065] In one possible implementation, such as Figure 1 As shown, the electric hand massager includes a processor and a voice receiver and / or operation button 4. The processor is used to receive operation signals from the voice receiver and / or operation button 4 and correspondingly activate at least one massage unit of the massage assembly 5.

[0066] Among them, the dual input method of voice receiver and operation button 4 can cover the user needs in different scenarios. Voice control is suitable for quick start or mode switching when the hands are limited, while physical buttons provide tactile feedback to meet the needs of scenarios with high requirements for operation certainty, such as the elderly or hearing-impaired people. Users can freely choose the operation method according to their usage habits or environment, which improves the universality of the device.

[0067] In one possible implementation, such as Figure 9 As shown, the massage unit includes a drive assembly 511 and a pressing assembly 512 connected to each other. The drive assembly 511 is located inside the mold mechanism 2, and at least a portion of the pressing assembly 512 can pass through the mold mechanism 2 to contact the hand. The drive assembly 511 drives the pressing assembly 512 to move along a preset trajectory.

[0068] The drive assembly 511 and the pressing assembly 512 are designed separately. The drive assembly 511 is built into the mold mechanism 2 to ensure drive stability. The pressing assembly 512 performs linear movement and pressure action. Through the constraint of the guide rail of the mold mechanism 2, the drive energy is efficiently converted into precise vertical pressing and trajectory sliding, reducing energy loss and mechanical noise.

[0069] The mold mechanism 2 has built-in linear slide rails and guide slide rails, which force the pressing component 512 to move along the preset meridian path, ensuring that the massage direction and angle are consistent with the biomechanical characteristics of traditional Chinese massage techniques, and preventing trajectory deviation or acupoint misses that are common in manual operation.

[0070] Among them, the drive component 511 and the pressing component 512 adopt a detachable connection design, and the worn parts can be replaced independently to avoid the overall scrapping. The outer shell 1 of the mold mechanism 2 isolates the drive area from contaminants such as sweat and dander, reducing the risk of corrosion of internal components.

[0071] Among them, the pressing component 512 that passes through the mold mechanism 2 adopts an elastic contact head design. Under the thrust of the driving component 511, it can adapt to the ups and downs of the hand bones and soft tissues. Through local deformation compensation, it achieves uniform pressure distribution and avoids excessive pressure on bony prominences by traditional rigid massage heads.

[0072] Understandably, the contact end of the pressing component 512 can also integrate a pressure sensor or pressure-sensing diaphragm. When excessive pressure is detected, the processor immediately triggers the pressing component 512 to retract in the reverse direction, ensuring that the pressing contact 5124 can be removed from the hand within 1 second, thereby improving safety.

[0073] In one possible implementation, such as Figures 9-11 As shown, the drive assembly 511 includes a first slider 5111, a drive motor, a lead screw 5112, and a spring telescopic rod 5113. The drive motor is poweredly connected to the lead screw 5112, and the first slider 5111 is threadedly connected to the lead screw 5112. The drive motor drives the lead screw 5112 to rotate, causing the first slider 5111 to slide along a preset trajectory. The first slider 5111 is connected to the pressing assembly 512 through the spring telescopic rod 5113, so that the pressing assembly 512 can move to conform to the palm mold groove 212 or the back of the hand mold groove 222.

[0074] The threaded engagement between the lead screw 5112 and the first slider 5111 converts the rotational motion of the drive motor into high-precision linear displacement, ensuring the positioning of the pressing component 512 along the preset trajectory. The spring telescopic rod 5113, as a flexible connecting medium, adapts to the curvature change of the mold groove through axial elastic extension and contraction, so that the pressing component 512 can move in accordance with the arc-shaped guide rail. The spring telescopic rod 5113 has multi-degree-of-freedom swing capability in the direction perpendicular to the mold groove. When the first slider 5111 slides along the axial direction of the lead screw 5112, the pressing component 512 can automatically adjust the tilt angle and contact depth according to the three-dimensional curved surface of the palm mold groove 212 or the back of the hand mold groove 222.

[0075] In one possible implementation, such as Figures 9-11As shown, the pressing assembly 512 includes a second slider 5121, an electric telescopic rod 5122, a compression spring 5123, and a pressing contact 5124. The first slider 5111 is connected to the second slider 5121 via the spring telescopic rod 5113. The second slider 5121 is provided with the electric telescopic rod 5122. The palm mold groove 212 or the back of the hand mold groove 222 is elastically connected to the pressing contact 5124 via the compression spring 5123. The compression spring 5123 applies a spring force to the pressing contact 5124 to move the pressing contact 5124 away from the hand. The output end of the electric telescopic rod 5122 is connected to the pressing contact 5124 so that the pressing contact 5124 can move towards the hand.

[0076] The spring 5123 has a pre-set elastic force that forms an opposite mechanical balance with the active thrust of the electric telescopic rod 5122. Under normal conditions, the spring 5123 keeps the pressing contact 5124 at a safe non-contact distance. When started, the electric telescopic rod 5122 overcomes the resistance of the spring 5123 and drives the contact to accurately approach the hand. The pressure is linearly controlled at the millimeter level by adjusting the rod stroke through electronic control, which avoids no-load impact and prevents overload compression of soft tissue.

[0077] In one possible implementation, such as Figures 9-11 As shown, the pressing contact 5124 includes a connecting part and an end part. The diameter of the connecting part is larger than the diameter of the end part. A transition part is provided between the connecting part and the end part. A part of the connecting part is located inside the mold mechanism 2. The guide slide rail includes a slide groove. The width of the slide groove is smaller than the diameter of the connecting part and larger than the diameter of the end part. The slide groove is provided with a number of holes corresponding to acupoints. The inner diameter of the holes is larger than the diameter of the connecting part, so that when the massage unit moves to the preset acupoint, the pressing contact 5124 can move towards the hand to stop and press the acupoint on the hand.

[0078] The interference fit between the groove width and the connecting diameter constrains the vertical freedom of the pressing contact 5124 in the non-acupuncture area, forcing the pressing contact 5124 to slide along a preset trajectory. When the contact moves to the hole corresponding to the acupoint, the gap between the connecting part and the hole releases its axial motion constraint, triggering the contact to press automatically. The diameter of the connecting part is greater than the width of the groove, forming a physical limit. The conical design of the transition part converts the lateral shear force of the groove on the contact into an axial compressive force, which is dispersed by the mold mechanism 2 and the outer shell 1. The design of the inner diameter of the hole being greater than the diameter of the connecting part reserves space for the contact to retract. When the massage unit continues to move after pressing, the wedge-shaped action of the side wall of the groove and the edge of the transition part generates a slope component force, forcing the connecting part to retract back to the inside of the hole and return to the sliding state.

[0079] In one possible implementation, such as Figure 6 and Figure 8As shown, the preset acupoints include: Kongzui, Lieque, Taiyuan, Yuji and Shaoshang of the Lung Meridian of Hand-Taiyin; Ximen, Neiguan, Daling, Laogong and Zhongchong of the Pericardium Meridian of Hand-Jueyin; Lingdao, Shenmen, Shaofu and Shaochong of the Heart Meridian of Hand-Shaoyin; Shangyang, Erjian, Sanjian, Hegu, Yangxi, Pianli and Wenliu of the Large Intestine Meridian of Hand-Yangming; Guanchong, Yemen, Zhongzhu, Yangchi, Waiguan, Zhigou, Huizong and Sanyangluo of the Sanjiao Meridian of Hand-Shaoyang; and Shaoze, Qiangu, Houxi, Wangu, Yanggu, Yanglao and Zhizheng of the Small Intestine Meridian of Hand-Taiyang.

[0080] Understandably, the guide track covers the core acupoints of the six main meridians of the hand (Lung Meridian, Pericardium Meridian, Heart Meridian, Large Intestine Meridian, Triple Energizer Meridian, and Small Intestine Meridian). By simultaneously stimulating several key nodes of multiple meridians, it selects iconic acupoints in each meridian that have both local treatment and systemic regulation functions. For example, the Taiyuan acupoint of the Lung Meridian regulates breathing, the Neiguan acupoint of the Pericardium Meridian improves palpitations, and the Hegu acupoint of the Large Intestine Meridian relieves headaches. Through multi-point linkage, it simultaneously addresses symptoms of multiple systems such as numbness in the hand, imbalance of cardiopulmonary function, and gastrointestinal disorders, achieving a compound conditioning effect with multiple benefits in one area.

[0081] In one possible implementation, such as Figure 1 and Figure 9 As shown, the electric hand massager may also include a wrapping part 6, which includes an airbag 61, a fan 62, and an electric heating wire 64. The airbag 61 is disposed inside the cylinder 11, and the cylinder 11 has a ventilation hole 63. The fan 62 and the electric heating wire 64 are disposed inside the cylinder 11 and correspond to the ventilation hole 63. The fan 62 is used to send air from outside the outer shell 1 into the cylinder 11 through the ventilation hole 63. After the air is heated by the electric heating wire 64, it forms hot air that fills the airbag 61, so that the airbag 61 is inflated to wrap around and fix the hand.

[0082] The wrapping part 6 draws in external air through the fan 62, which is then heated by the electric heating wire 64 to form a hot airflow that fills the airbag 61. This causes the airbag 61 to expand and conform to the contour of the hand, forming a bionic wrapping interface that matches the contour of the hand in real time. This achieves both flexible fixation and heat therapy. The hot air circulation system can adjust the temperature as needed. The warmth of the hot air stimulates the dilation of capillaries in the hand. Applying heat before massage can enhance blood circulation and relieve muscle tension, thus achieving a better massage effect.

[0083] When the airbag 61 is inflated, it forms a dynamic support interface. When the pressure contact 5124 presses the acupoint, it contacts the skin through the flexible layer of the airbag 61. The elastic deformation of the airbag 61 converts the concentrated point pressure into area pressure, which not only maintains the precise penetration of acupoint stimulation, but also reduces the stress peak of the bony prominence through the distributed rebound of the airbag 61, avoiding the risk of subcutaneous bruising caused by direct pressure from the pressure contact 5124.

[0084] Understandably, the hand electric massager may also include an exhaust valve to balance the air pressure within the airbag 61.

[0085] Furthermore, the airbag 61 material combines thermal conductivity, elasticity, and air tightness, and the airbag 61 can be made of materials such as rubber and plastic.

[0086] In one possible implementation, such as Figure 3 and Figure 9 As shown, the finger limiting mechanism 3 includes a first limiting member 31, a second limiting member 32, a third limiting member 33, and a fourth limiting member 34 arranged sequentially from top to bottom. The first limiting member 31 is used to form a barrier between the thumb and the index finger, the second limiting member 32 is used to form a barrier between the index finger and the middle finger, the third limiting member 33 is used to form a barrier between the middle finger and the ring finger, and the fourth limiting member 34 is used to form a barrier between the ring finger and the little finger.

[0087] Among them, four limiting members are located between adjacent fingers to form a barrier. The height difference of the limiting members matches the physiological opening angle between the fingers at 12 degrees, ensuring that the hand can be in the correct position, which facilitates the accuracy of subsequent massage.

[0088] Furthermore, such as Figure 3 and Figure 9 As shown, the limiting member includes an upper partition 311, a lower partition 312, and a connecting rod 313. The upper partition 311 is used to contact the finger located on the upper side, and the lower partition 312 is used to contact the finger located on the upper side. The upper partition 311 and the lower partition 312 are connected to the housing 1 or the mold mechanism 2 through the connecting rod 313.

[0089] The upper and lower curved partitions 311 and 312 are curved to match the physiological curvature of the upper and lower sides of the fingers. The upper partition 311 and the lower partition 312 are fixed in the middle of the receiving cavity by the connecting rod 313, and the finger position is defined by the double curved surfaces.
