Description

Technical Field

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

[0002] Massage is a common health practice used in daily life to relieve fatigue and stress. With the increasingly fast pace and high pressure of modern life, the demand for massage has also increased. Massage methods include both manual and mechanical massage. However, due to busy work schedules and various tasks, people's leisure time is often fragmented, making it difficult to dedicate large amounts of time to manual massage. Therefore, mechanical massage has become the mainstream method. Mechanical massage typically targets specific parts of the body, such as the neck, shoulders, waist, or hands. Among these, hand massage devices primarily serve to... To relieve muscle fatigue in the fingers and palms and improve blood circulation in the hands, hand massage devices come in various shapes and structures. Some are worn on the arm or palm, while others are held between the fingers. In practical applications, hand massage devices worn on the forearm massage the forearm through pressing and other methods, while hand massage devices held between the fingers massage the fingers. It is evident that current hand massage devices only target specific local areas of the hand and cannot be used to massage other local areas besides the forearm. In other words, hand massage devices cannot be used to massage the palm and fingers of the hand in addition to the forearm. Utility Model Content

[0008] In the aforementioned hand massage device, the massage head is provided with a recessed cavity, which is open toward the port of the support portion.

[0009] In the aforementioned hand massage device, a protective sleeve is provided on the outer side of the drive seat, which is coaxially arranged with the support portion. The two ends of the protective sleeve are open, and the support portion is located inside the protective sleeve.

[0010] In the aforementioned hand massage device, the protective sleeve is connected to the drive seat, and the drive seat is also fixed with a second drive assembly for driving the support part to rotate. The power output end of the second drive assembly is located inside the protective sleeve and is in transmission cooperation with the support part; the support part rotates with the protective sleeve along its circumference.

[0011] In the aforementioned hand massage device, a drive gear is provided on the power output end of the second drive component, and a toothed ring is fitted on the outer peripheral surface of the support portion. The toothed ring is fixed on the support portion and meshes with the drive gear.

[0012] In the aforementioned hand massage device, a protective cover is provided on the outer side of the drive seat, the inner cavity of the protective cover is open to the drive seat and the support part, and the port at one end of the support part is directly opposite the inner cavity of the protective cover.

[0013] In the aforementioned hand massage device, two protective plates are provided on the outer side of the drive seat, and the support part is located between the two protective plates.

[0014] In the aforementioned hand massage device, the support portion slides along its axial direction with the outer side of the drive seat. The drive seat also has a third drive assembly fixed inside for driving the support portion to reciprocate. The power output end of the third drive assembly passes through one side of the drive seat and extends to the outer side of the drive seat. The support portion is in a transmission engagement with the power output end of the third drive assembly.

[0015] In the aforementioned hand massage device, a guide rail is fixed on the outer side of the drive seat. The guide rail is parallel to the axis of the support portion, and the outer side of the support portion slides in cooperation with the guide rail along the extension direction of the guide rail.

[0016] In the aforementioned hand massage device, a guide groove is provided on the outer side of the support portion, and the axis of the guide groove is perpendicular to the axis of the support portion; a turntable is provided inside the drive seat, and the end face of the turntable penetrates through one side of the drive seat and faces the guide groove; the turntable is rotatably engaged with the drive seat and is also in transmission engagement with the power output end of the third drive component.

[0020] The beneficial effects of this utility model after adopting the above technical solution are as follows:

[0021] This technical solution involves providing a support portion on the outer side of the drive seat. The forearm is placed on the support portion with the palm facing the massage head. The massage head on the drive seat touches the palm. Because the massage head is located on the outer end of the swing shaft (i.e., the end of the swing shaft outside the drive seat), when the first drive assembly drives the swing shaft to rotate, the swinging outer end causes the massage head to rotate eccentrically around the inner end of the swing shaft (i.e., the end of the swing shaft inside the drive seat) as the rotation center. This causes the massage head to alternately move closer to and away from the palm; that is, the distance between the massage head and the palm changes with the eccentric rotation of the massage head. The continuous cycle creates an intermittent swaying motion that touches the palm, providing a continuous rubbing massage effect. Similarly, if the fingers are facing the massage head, the massage head will rub the fingers. Conversely, if the palm is placed on top of the hand with the forearm facing the massage head, the drive shaft on the drive base will cause the massage head to intermittently touch the forearm, providing a rubbing massage effect. This allows the hand massage device to be compatible with different parts of the hand, and can be used to massage the forearm, palm, and fingers for multi-purpose massage.

[0036] The technical solution of this utility model will be further described in detail below with reference to specific embodiments, but this does not constitute any limitation on this utility model.

[0037] Example 1:

[0038] like Figure 1-6 As shown, the hand massage device includes a drive base 1 and a support part 2. The support part 2 is located on the outer side of the drive base 1. A first drive assembly 5 is fixed inside the drive base 1. A swing shaft 4 that passes through the drive base 1 is provided on the power output end of the first assembly. The swing shaft 4 extends to the outer side of the drive base 1 and rotates with the drive base 1. A massage head 3 is provided on the outer side of the drive base 1. The massage head 3 is located on the swing shaft 4. The swing shaft 4 is provided with a bent part 41 for driving the massage head 3 to swing towards the support part 2.

[0039] The specific working principle is as follows: This technical solution provides a support part 2 on the outer side of the drive seat 1. The forearm is placed on the support part 2, with the palm facing the massage head 3. The massage head 3 on the drive seat 1 touches the palm. Because the massage head 3 is located on the outer end of the swing shaft 4 (i.e., the end of the swing shaft 4 located outside the drive seat 1), when the first drive assembly 5 drives the swing shaft 4 to rotate, the swinging outer end causes the massage head 3 to rotate eccentrically around the inner end of the swing shaft 4 (i.e., the end of the swing shaft 4 located inside the drive seat 1) as the center of rotation. This causes the massage head 3 to alternately move closer to and away from the palm, that is, the distance between the massage head 3 and the palm... As the massage head 3 rotates eccentrically, the movement continuously changes, creating an intermittent oscillating motion that touches the palm, providing a continuous rubbing massage effect. Similarly, if the fingers are facing the massage head 3, the massage head 3 provides a rubbing massage effect on the fingers. Conversely, when the palm is placed on the hand with the forearm facing the massage head 3, the drive base 1, via the drive swing shaft 4, causes the massage head 3 to intermittently touch the forearm, providing a rubbing massage effect on the forearm. This allows the hand massage device to be compatible with different parts of the hand, and can be used to massage the forearm, palm, and fingers for multi-purpose massage.

[0040] In a specific configuration, the bending portion 41 is located between the inner and outer ends of the pendulum shaft 4; wherein, the bending portion can be a structure in which the two ends of the pendulum shaft intersect in a straight line, or a structure in which the two ends of the pendulum shaft are arc-shaped transitions. This embodiment does not impose too many restrictions on this.

[0041] As a further improvement, the support part 2 has a cylindrical structure, and both ends are open.

[0042] The support part 2 is cylindrical, allowing it to be fitted onto the forearm or palm. Once worn, the massage head 3 can be positioned on the front or back of the forearm, palm, and fingers as needed to meet the rubbing needs of different sides, reducing usage limitations and improving product usability.

[0043] In this embodiment, the support portion 2 is specifically a flexible sleeve with open ends.

[0044] In a specific implementation, the massage head 3 is a flexible body, fixed on the drive seat 1, and tilted towards the port side of the support part 2; the swing shaft 4 is inserted into the massage head 3 and rotates in cooperation with the massage head 3.

[0045] The massage head 3 is tilted towards the port side of the support portion 2, so that the massage head 3 always faces the inner cavity of the support portion 2, and is fixed to the drive seat 1 in this posture. Whenever the swing shaft 4 rotates, the outer end of the swing shaft 4 swings inside the massage head 3. Through the rotation of the massage head 3, the outer end of the swing shaft 4 continuously squeezes the massage head 3 from inside the massage head 3 along the swing path. After being squeezed, the flexible massage head 3 produces deformation bending with the junction of the massage head 3 and the drive seat 1 as the fulcrum and in the same direction as the squeezing of the outer end of the swing shaft 4. When the outer end of the swing shaft 4 rotates to the side of the swing shaft 4 away from the inner cavity of the support portion 2, the outer end of the swing shaft 4 squeezes... Pressing the massage head 3 moves it away from the inner cavity of the support part 2. Conversely, when the outer end of the swing shaft 4 rotates to the side of the swing shaft 4 adjacent to the inner cavity of the support part 2, the swinging outer end drives the massage head 3 to approach the inner cavity of the support part 2 again. This cycle repeats continuously, allowing the massage head 3 to intermittently touch the forearm, palm, or fingers. Since the massage head 3 moves away from and towards the inner cavity of the support part 2 through its own deformation, the swing amplitude is smaller and the force is gentler compared to swinging synchronously with the outer end of the swing shaft 4. This also indirectly increases the swing frequency, which shortens the interval between each touch, thereby forming a continuous pressing sensation, enhancing the stimulation effect and improving comfort.

[0046] In this embodiment, the massage head 3 is preferably fixed on the drive seat 1. When the massage head 3 is fixed on the drive seat 1, the massage head 3 and the outer end of the swing shaft 4 generate relative movement to reduce the swing amplitude of the massage head 3 and increase the touch frequency of the massage head 3. Alternatively, the massage head 3 can also be fixed on the outer end of the swing shaft 4. When the massage head 3 is fixed on the outer end of the swing shaft 4, the massage head 3 and the outer end of the swing shaft 4 rotate synchronously and eccentrically.

[0047] Combination Figure 3 and Figure 6 As shown, in actual use, the massage head 3 has a retainer 32 fixed inside, and the outer end of the swing shaft 4 is provided with a chuck 42. The chuck 42 is fitted inside the retainer 32 and rotates with the retainer 32.

[0048] Combination Figure 4 , Figure 5 and Figure 6 As shown, preferably, the massage head 3 is provided with a cavity 33, and the cavity 33 is open at one end facing the support part 2.

[0049] The concave cavity 33 allows the massage head 3 to be fitted onto the fingertip, thereby driving the finger head to move and rub the finger. Specifically, as the massage head 3 swings, it drives the finger head to swing synchronously, performing massage stimulation by repeatedly pulling the finger head, thus enhancing the massage effect on the finger.

[0050] In some embodiments, a protective sleeve 11 is provided on the outer side of the drive seat 1, which is coaxially arranged with the support portion 2. The two ends of the protective sleeve 11 are open, and the support portion 2 is disposed inside the protective sleeve 11.

[0051] The protective sleeve 11 allows the drive seat 1 to cover the support part 2, and also covers the forearm or palm during use, thus improving privacy.

[0052] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the protective sleeve 11 is connected to the drive seat 1, and a second drive assembly 6 for driving the support part 2 to rotate is fixed inside the drive seat 1. The power output end of the second drive assembly 6 is located inside the protective sleeve 11 and is in transmission cooperation with the support part 2; the support part 2 rotates in cooperation with the protective sleeve 11 along its circumference.

[0053] The support part 2 rotates within the inner cavity of the sleeve 11, causing the inner circumferential surface of the support part 2 to rub the forearm or arm along the circumference of the forearm or palm. The rotation generates friction with the forearm or palm, increasing the tactile sensation in the circumferential direction of the forearm or palm, thus enriching the layers of massage stimulation and enhancing the massage effect.

[0054] Combination Figure 2 and Figure 3 As shown, the specific connection between the second drive assembly 6 and the support part 2 is as follows: a drive gear 61 is provided on the power output end of the second drive assembly 6, and a toothed ring 72 is fitted on the outer peripheral surface of the support part 2. The toothed ring 72 is fixed on the support part 2 and meshes with the drive gear 61.

[0055] In addition, the second drive assembly 6 and the support part 2 can also adopt other connection methods, such as setting a pulley on the power output end of the second drive assembly 6 and sleeve the belt on the outer circumferential surface of both the support part 2 and the pulley. The belt can be a flat belt, a V-belt, or a synchronous belt. That is, a belt drive mechanism is constructed between the second drive assembly 6 and the support part 2, so that the second drive assembly 6 drives the support part 2 to rotate in the inner cavity of the protective cylinder 11. This embodiment does not impose too many restrictions on the specific connection method between the second drive assembly 6 and the support part 2.

[0056] In the specific configuration, a first bracket 7 fixed to the support part 2 is sleeved on the outer peripheral surface of the support part 2, and a toothed ring 72 is sleeved on the outer peripheral surface of the first bracket 7. A convex ring 71 coaxially arranged is also provided on the outer peripheral surface of the first bracket 7. The convex ring 71 is embedded in the inner peripheral surface of the protective cylinder 11 and rotates with the inner peripheral surface of the protective cylinder 11. Preferably, there are two convex rings 71, which are spaced apart along the axial direction of the support part 2 to avoid the first bracket 7 having only a single convex ring 71 forming a single fulcrum contact in the inner cavity of the protective cylinder 11, and to prevent the two ends of the flexible body from swaying and shaking at this fulcrum.

[0057] In some embodiments, a protective cover 14 is provided on the outer side of the drive seat 1, the inner cavity of the protective cover 14 is open to the drive seat 1 and the support part 2, and the port of one end of the support part 2 is directly opposite the inner cavity of the protective cover 14.

[0058] The protective cover 14 can be used to hide the massage area and also to cover the massage head 3. When the massage head 3 and the protective cover 14 are positioned opposite each other at the axial ends of the support part 2, the forearm is inserted into the inner cavity of the support part 2 from the end of the support part 2 adjacent to the massage head 3, and the protective cover 14 hides the palm and fingers inside, while the massage head 3 rubs the forearm. When the massage head 2 is placed inside the protective cover 14, the forearm is inserted into the inner cavity of the support part 2 from the end of the support part 2 away from the massage head 3 (i.e., the opposite end of the support part 2), and the protective cover 14 serves to cover the massage head 3, the palm and fingers, while the massage head 3 rubs the fingers.

[0059] In some embodiments, one end of the sleeve 11 is connected to the inner cavity of the cover 14, so that the drive seat 1 can cover the massage head 3, palm and fingers, as well as the support part 2 and forearm.

[0060] In some embodiments, two protective plates 13 are provided on the outer side of the drive seat 1, and the support part 2 is located between the two protective plates 13.

[0061] Combination Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the support portion 2 slides along its axial direction with the outer side of the drive seat 1, and a third drive assembly 8 for driving the support portion 2 to reciprocate is also fixed inside the drive seat 1. The power output end of the third drive assembly 8 passes through one side of the drive seat 1 and extends to the outer side of the drive seat 1; the support portion 2 and the power output end of the third drive assembly 8 are in a transmission engagement.

[0062] The support part 2 slides back and forth on the outer side of the drive seat 1, so that the inner circumferential surface of the support part 2 rubs the forearm or palm along the axis of the forearm or palm. By using the sliding and friction with the forearm or palm, the tactile sensation of the forearm or palm in the axial direction is enhanced, thereby enriching the layers of massage stimulation and enhancing the massage effect. In addition, it can also avoid the forearm or palm from rubbing itself by manual movement within the support part 2, making it more convenient to use, requiring no extra exercise, saving physical strength, and taking care of users who are physically weak or elderly.

[0063] Combination Figure 5 and Figure 6 As shown, the specific structure of the sliding fit between the support part 2 and the outer side of the drive seat 1 is as follows: a guide rail is fixed on the outer side of the drive seat 1, the guide rail is parallel to the axis of the support part 2, and the outer side of the support part 2 slides with the guide rail along the extension direction of the guide rail.

[0064] The guide rail includes two spaced guide posts 12, the axes of which are parallel to the axis of the support portion 2. The two ends of the two guide posts 12 are respectively fixed to the outer side of the drive seat 1. The outer side of the support portion 2 slides with the two guide posts 12 along the axial direction. In a specific configuration, a second bracket 9 fixed to the support portion 2 is fitted on the outer circumferential surface of the support portion 2. The second bracket 9 has guide holes located on opposite sides of the support portion 2. The guide holes on both sides correspond one-to-one with the two guide posts 12 and slide with each other.

[0065] The specific connection between the support part 2 and the third drive assembly 8 is as follows: a guide groove 91 is provided on the outer side of the support part 2, and the axis of the guide groove 91 is perpendicular to the axis of the support part 2; a turntable 81 is provided inside the drive seat 1, and the end face of the turntable 81 passes through one side of the drive seat 1 and is directly opposite the guide groove 91; the turntable 81 is rotatably engaged with the drive seat 1 and is also in transmission engagement with the power output end of the third drive assembly 8.

[0066] The edge of the turntable 81 is provided with a sliding post 811 inserted into the guide groove 91. The sliding post 811 slides and engages with the guide groove 91 along the length of the guide groove 91, and rotates and engages with the guide groove 91 along the circumference of the sliding post 811.

[0067] The principle of the reciprocating sliding of the turntable 81 and the support 2 is as follows: when the third drive assembly 8 drives the turntable 81 to rotate, it drives the sliding column 811 to rotate around the center of the turntable 81, and generates four working stages within the guide groove 91. In the first stage, the sliding column 811 moves from one side of the axis of the support 2 to the opposite side of the axis, and moves along the length of the guide groove 91 within the guide groove 91. In the second stage, the sliding column 811 generates axial displacement of the support 2 on one side of the axis of the support 2, and pushes the guide groove 91 to move along the width of the guide groove 91 within the guide groove 91. In the first stage, the guide groove 91 drives the support part 2 to move along the guide rail; in the second stage, the slide column 811 returns from the opposite side of the axis of the support part 2 to the starting side of the axis, and the slide column 811 moves in the opposite direction along the length of the guide groove 91; in the third stage, the slide column 811 generates a reverse displacement along the axial direction of the support part 2 on the opposite side of the axis of the support part 2, and the slide column 811 pushes the guide groove 91 to move in the opposite direction along the width of the guide groove 91, and the guide groove 91 drives the support part 2 to move in the opposite direction along the guide rail. The four working stages of the slide column 811 constitute a working cycle.

[0068] In the specific configuration, the guide groove 91 is opened on the second bracket 9 and is located between the two guide posts 12. In addition, the guide groove 91 can also be opened on the outer side of the support part 2 and locally hardened, or a slide rail can be fixed on the outer side of the support part 2. This embodiment does not impose too many restrictions on this.

[0069] The specific connection between the third drive assembly 8 and the turntable 81 is as follows: the power output end of the third drive assembly 8 is provided with a driving bevel gear 82, and the turntable 81 is provided with a driven bevel gear 83 arranged coaxially. The driven bevel gear 83 meshes with the driving bevel gear 82. In addition, the turntable 81 and the third drive assembly 8 can also be connected by conventional transmission mechanisms such as belt drive and worm gear drive. This embodiment does not impose too many restrictions on this.

[0070] In other connection methods between the third drive assembly 8 and the turntable 81, a worm gear is provided on the power output end of the third drive assembly 8, and a worm wheel is connected to the turntable 81 on the same axis. The worm wheel and the worm gear are meshed and connected, that is, a worm gear transmission mechanism is constructed between the third drive assembly 8 and the turntable 81, so that the third drive assembly 8 drives the turntable 81 to rotate in the drive seat 1.

[0071] Combination Figure 2 and Figure 5 As shown, in a further improvement, the inner circumferential surfaces of both ends of the support portion 2 are provided with first protrusions 21, and the inner circumferential surfaces of the support portion 2 are also provided with several second protrusions 22 arranged at intervals, with the second protrusions 22 located between the two first protrusions 21.

[0072] Preferably, the first protrusion 21 is provided at the inner edges of both ends of the support portion 2.

[0073] The first protrusion 21 is designed so that the support part 2 only clamps onto the forearm or palm through its two ends, reducing the contact area between the middle part of the support part 2 and the forearm or palm, thereby reducing the sliding resistance of the forearm or palm in the support part 2. This allows the forearm or palm to receive the squeezing sensation of massage stimulation, and also allows the forearm or palm to move smoothly in the support part 2.

[0074] Several second protrusions 22 are arranged at intervals, which can increase the contact points with the forearm or palm through multi-point contact without significantly increasing the movement resistance of the forearm or palm within the support part 2, thereby improving the texture of the squeezing effect and enhancing the tactile sensation of massage stimulation.

[0075] The arrangement of the second protrusions 22 can be varied. In this embodiment, the second protrusions 22 are spirally arranged from one end of the support portion 2 along the axial direction of the support portion 2 and spaced apart to the opposite end of the support portion 2. In addition, the support portion 2 can also be arranged in multiple matrix arrays or in multiple staggered arrangements. This embodiment does not impose too many restrictions on this.

[0076] In some embodiments, the support portion 2 is a non-cylindrical structure, and the first protrusion 21 and the second protrusion 22 are provided on the side of the support portion 2 opposite to the drive seat.

[0077] In this embodiment, the first drive assembly 5, the second drive assembly 6, and the third drive assembly 8 are all motor assemblies. The motor assembly mainly consists of a motor and a reducer. The reducer is connected to the power output end of the motor, while the inner end of the swing shaft 4 and the outer side of the support 2 are respectively connected to the power output end of the corresponding reducer. In addition, a rotary cylinder assembly and a hydraulic motor assembly can be used as power sources to replace the motors. This embodiment does not impose too many restrictions on this.

[0078] In addition, the massage head 3 is equipped with a vibration motor 31, which allows the massage head 3 to not only rub the forearm or palm, but also to vibrate the fingers at high frequency through the vibration motor 31, thereby enhancing the intensity of massage stimulation and enriching the user experience.

[0079] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
