Description

Technical Field

[0001] This utility model relates to the field of medical and health care technology, and in particular to a massage device. Background Technology

[0002] With social development and the gradual improvement of living standards, people are paying more and more attention to their health and the comfort of life. Medical and health care products, such as massage devices, are becoming increasingly popular.

[0003] Most existing massage devices use a motor to drive the massage head in a linear reciprocating motion, rapidly tapping the areas of the body that need massage, such as the shoulders, neck, waist, head, and legs, to stimulate muscles and relax the mind and body. However, the interaction between the massage head and the massaged area is a point-to-point tapping motion, which has drawbacks such as a single mode of action and a small range of action, making it difficult to achieve the ideal massage effect. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a massage device that can effectively increase the range of action and improve the user experience.

[0005] To achieve the above objectives, this utility model provides a massage device, including a housing and a drive mechanism. The housing includes a massage part made of a flexible material. The drive mechanism is disposed in the housing and includes a reduction gearbox and a drive shaft. The drive shaft includes a first connecting end and a second connecting end opposite to each other. The first connecting end is connected to the reduction gearbox, and the second connecting end is inserted into the massage part. The first connecting end and the second connecting end of the drive shaft are arranged at an angle to each other. Under the drive of the reduction gearbox, the massage part rotates with the second connecting end around the first connecting end.

[0006] In some embodiments, the massage section is provided with a vibrating element, which rotates with the second connecting end about the first connecting end.

[0007] In some embodiments, the massage part and the second connecting end rotate at a speed not exceeding 1000 revolutions per minute about the first connecting end.

[0008] In some embodiments, the reduction gearbox includes a motor and a reduction gear set connected to the output shaft of the motor; the reduction gear set includes a plurality of meshing gears, and the reduction ratio of the reduction gear set is from 4:1 to 100:1.

[0009] In some embodiments, the output shaft of the gearbox is arranged perpendicularly or at an angle relative to the output shaft of the motor.

[0010] In some embodiments, the drive mechanism further includes a reversing gear set, which is connected between the reduction gear set of the reduction gearbox and the first connecting end of the drive shaft, wherein the output shaft of the reduction gearbox is angled to the first connecting end of the drive shaft.

[0011] In some embodiments, the second connecting end of the drive shaft is inclined relative to both the first connecting end and the output shaft of the gearbox.

[0012] In some embodiments, the massage portion is spherical or ellipsoidal, and the central axis of the first connecting end is inclined relative to the central axis of the massage portion; and / or, the central axis of the massage portion is substantially coaxial with the central axis of the second connecting end.

[0013] In some embodiments, the housing is recessed to form a bowl-shaped portion, and the massage portion is integrally connected to the center of the bottom of the bowl-shaped portion and extends at least partially outward relative to the bowl-shaped portion.

[0014] In some embodiments, the bowl-shaped portion includes an inner layer and an outer layer covering the inner layer, the hardness of the inner layer is greater than the hardness of the outer layer, and the massage portion is integrally connected to the outer layer of the bowl-shaped portion.

[0015] In some embodiments, the housing is an elongated structure, including opposing front and rear ends, and a middle section located between the front and rear ends. The rear end serves as a handle for easy gripping by the user. A first vibration motor is provided at the front end of the housing, and the massage part is located at the front or middle section of the housing, with a second vibration motor inside. Alternatively, the housing may further include a branch extending upward from its rear end toward the middle section, with the massage part located at the end of the branch and a second vibration motor inside.

[0016] Compared to existing technologies, the massage device provided by this utility model uses a reduction gearbox as a drive, enabling the drive shaft to rotate at an appropriate speed. The massage part rotates around the first connection end under the drive of the second connection end of the drive shaft to form a circular motion trajectory, producing a massage effect similar to human hand kneading on the massaged area. Compared to the tapping mode of existing massage devices, it not only has a larger working area but is also more comfortable, effectively improving the user experience. Attached Figure Description

[0029] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. One or more embodiments of this utility model are exemplarily shown in the drawings to enable a more accurate and thorough understanding of the disclosed technical solutions. However, it should be understood that this utility model can be implemented in many different forms and is not limited to the embodiments described below.

[0030] This utility model provides a massage device, mainly used for massage and relaxation of the human body. For example... Figure 1-5The diagram illustrates a specific embodiment of the massage device of this utility model. The massage device 100 includes a housing 10 and a drive mechanism 20 disposed within the housing 10. The housing 10 is provided with a massage part 30, and the drive mechanism 20 is tractively connected to the massage part 30. Under the action of the drive mechanism 20, the massage part 30 rotates around a first axis X1 to form a circular motion trajectory. Areas of the human body requiring massage and relaxation, such as the head, neck, back, waist, and legs, as long as they are within the range of the circular trajectory, can continuously contact and separate from the massage part 30, creating a kneading stimulation effect.

[0031] The massage part 30, as the component of the massage device of this utility model that directly acts on the human body, can be made of silicone, rubber, etc., possessing a certain degree of flexibility. When acting on the human body, it provides a soft touch and can play a certain cushioning role, increasing the comfort of the massage. Of course, the massage part 30 can also be made of other flexible materials that can directly contact the skin; this utility model does not limit this. Compared to the point-to-point tapping of existing massage devices, the movement trajectory of the massage part 30 in this application is roughly circular, specifically circular, elliptical, etc., allowing for a larger effective area; moreover, the kneading method is similar to human hand massage, resulting in a more comfortable user experience.

[0032] Please also refer to Figure 5-6 The drive mechanism 20 includes a reduction gearbox 22 and a drive shaft 24. The drive shaft 24 includes a first connecting end 24a and a second connecting end 24b, which extend obliquely relative to the first connecting end 24a, forming an included angle β, preferably an obtuse angle. After assembly, the first connecting end 24a of the drive shaft 24 is connected to the output shaft 229 of the reduction gearbox 22, and the second connecting end 24b is fixedly inserted into the massage part 30. Thus, the reduction gearbox 22 can drive the drive shaft 24, thereby causing the massage part 30 to rotate around a first axis X1, which can be the central axis of the first connecting end 24a.

[0033] In this embodiment, the massage portion 30 is generally spherical or ellipsoidal in shape and is substantially coaxial with the second connecting end 24b of the drive shaft 24. An angle α is formed between the central axis X2 of the massage portion 30 and the first axis X1, preferably an acute angle, and more preferably less than 45°. The angle β between the first connecting end 24a and the second connecting end 24b is complementary to the angle α between the first axis X1 and the central axis X2, i.e., α + β = 180°. Thus, the deflection angle of the central axis X2 of the massage portion 30 relative to the first axis X1 can be determined by the angle between the first connecting end 24a and the second connecting end 24b of the drive shaft 24, thereby determining the rotation radius of the massage portion 30.

[0034] like Figure 6As shown, the reduction gearbox 22 includes a motor 221 and a reduction gear set 223. The motor 221 can be a DC motor or the like, and has a high-speed rotating output shaft 222. The reduction gear set 223 includes a gearbox 225 and a plurality of gears 227 disposed within the gearbox. The gears 227 mesh with each other, and the overall reduction ratio of the reduction gear set 223 can be determined by designing the gear ratio. In a specific embodiment, the reduction ratio of the reduction gear set 223 is not less than 4:1 and not greater than 100:1, so that the rotational speed of the output shaft 229 of the reduction gearbox 22 does not exceed 1000 rpm, and thus the rotational speed of the drive shaft 24 and the massage part 30 does not exceed 1000 rpm.

[0035] In one specific embodiment, a vibrating element 40, such as a vibrating motor, is provided inside the massage part 30. The vibrating element 40 can be integrally fixed inside the massage part 30 during the molding process. While rotating, the massage part 30 can vibrate at a predetermined frequency with the vibrating element 40. In this way, while stimulating the massaged area through kneading, it can also produce a deep stimulation effect on the massaged area through vibration. The superposition of these two different types of stimulation effects allows the meridians, blood vessels, and iliac muscles of the massaged area to be unblocked and relaxed, effectively relieving discomfort in people's exercise, work, and daily life, such as relieving superficial muscle swelling and soreness, resulting in better massage effect and user experience.

[0036] In this embodiment, as Figure 1-2 As shown, the housing 10 is generally a longitudinally elongated rod-shaped structure, with the massage part 30 disposed at the front end of the housing 10. Specifically, the front end of the housing 10 is laterally bent, and its end face is concave to form a bowl-shaped portion 52. Preferably, the bowl-shaped portion 52 is arranged around a first axis X1, which is approximately perpendicular to the length direction of the housing 10. The massage part 30 is disposed in the bowl-shaped portion 52, with one end serving as a connecting end, connected to the center of the bottom of the bowl-shaped portion 52; the other end serves as a free end, extending outward from the open end 53 of the bowl-shaped portion 52. When the massage part 30 is driven to rotate, it oscillates within the bowl-shaped portion 52 around its connecting end.

[0037] Preferably, the bowl-shaped portion 52 has a double-layer structure, specifically including an outer layer 52a and an inner layer 52b encased within the outer layer 52a. The outer layer 52a is made of a flexible material, and the massage portion 30 extends integrally outward from the center of the bottom of the outer layer 52a. The inner layer 52b is made of a rigid material, such as plastic or metal, and provides support for the outer layer 52a and the massage portion 30. In a specific embodiment, the housing 10 may have a double-layer structure, including a flexible outer shell and a rigid inner shell. The inner shell provides support for internal components such as the drive mechanism 20, and the outer shell is integrally encased outside the inner shell. The inner layer 52b of the bowl-shaped portion 52 may be part of the inner shell, and the outer layer 52a may be part of the outer shell.

[0038] Preferably, after the inner shell is molded separately and assembled with internal components such as the drive mechanism 20, the outer shell and massage part 30 are integrally molded by injection molding. This not only simplifies production and assembly but also improves the connection strength between the massage part 30 and the outer shell. During rotation around the first axis X1, the massage part 30 can deform to a greater extent without damage, further enhancing the force and range of the massage part 30 applied to the human body. Furthermore, the outer shell integrally wraps around the inner shell, providing a good seal for the drive mechanism 20 and other internal components, serving as a waterproof and dustproof barrier, and facilitating the cleaning and storage of the massage device 100.

[0039] Of course, in the massage device 100 of this utility model, the outer shell and the massage part 30 can also be molded separately and then connected as a whole, so that the massage part 30 can be selectively disassembled and replaced. In practical applications, the massage device 100 can be equipped with multiple massage parts 30 with different structures or shapes. Users can select the appropriate type of massage part 30 according to the different massage positions, so that the shape of the massage part 30 can better adapt to the massaged area and further improve the massage effect. At this time, the material of the outer shell is no longer limited to the material of the massage part 30; it can be made of flexible materials such as silicone and rubber, or hard materials such as plastic and alloy.

[0040] like Figure 3 As shown, in the extension direction of the first axis X1, the depth of the bowl-shaped portion 52 is less than the height of the massage portion 30, so that the massage portion 30 partially extends beyond the open end 53 of the bowl-shaped portion 52, allowing it to easily contact the area being massaged. The vibrating element 40 is integrally fixed in the portion of the massage portion 30 that extends beyond the bowl-shaped portion 52, allowing it to be closer to the area being massaged. The central axis X2 of the massage portion 30 coincides with or is parallel to the central axis of the second connecting end 24b, and the central axis of the bowl-shaped portion 52 coincides with or is parallel to the central axis of the first connecting end 24a, so that the massage portion 30 is eccentrically arranged relative to the bowl-shaped portion 52, with its middle part close to the inner edge of the open end 53 of the bowl-shaped portion 52.

[0041] Driven by the reduction gearbox 22, the drive shaft 24 can drive the massage unit 30 to rotate around the first axis X1 at an appropriate speed, such as no more than 1000 rpm. The first connecting end 24a of the drive shaft 24 rotates around its central axis, i.e., the first axis X1, while the second connecting end 24b and the massage unit 30 connected to it revolve around the first connecting end 24a, or the first axis X1. The revolution path of the massage unit 30 around the first connecting end 24a is approximately circular. The portion of the body to be massaged that falls within this circular path can interact with the massage unit 30, thereby achieving a wide-area kneading massage effect.

[0042] like Figure 7As shown, on a plane perpendicular to the first axis X1, the projection of the massage part 30 itself is approximately a circle with radius R1, and the projection of the open end 53 of the bowl-shaped part 52 is approximately a circle with radius R2. The centers of the two circles are offset by a certain distance. During the rotation of the massage part 30 around the first axis X1, it oscillates relative to the center of the bottom of the bowl-shaped part 52. The bowl-shaped part 52 provides some support for the rotation of the massage part 30 and also restricts its rotation path. In this application, the massage part 30 rotates relative to the first axis X1, and its trajectory is approximately a circle with radius R3, where R3 > R1.

[0043] In the existing structure, the massage part achieves massage by frequently tapping the human body. The area of ​​the massage part with a radius of R1 acting on the human body is approximately a circle with a radius of R1, which is much smaller than the effective range of the massage device of this application (a circle with a radius of R3). Thus, without changing the size of the massage part 30 itself, a larger effective area can be obtained on the human body by changing the movement mode of the massage part 30, resulting in a better massage effect. Of course, depending on the massage area, the massage part 30 itself can have different sizes; and / or, the massage part 30 can be deflected at different angles relative to the bowl-shaped part 52, thereby further increasing the effective range of the massage part 30 on the human body.

[0044] In one embodiment, such as Figure 8 As shown, without changing the dimensions of the bowl-shaped portion 52 and the massage portion 30 itself, the angle α between the central axis X2 of the massage portion 30 and the first axis X1 is increased, causing the massage portion 30 to deflect further outward relative to the bowl-shaped portion 52. This increases the distance between the center of the projection of the massage portion 30 onto the plane perpendicular to the first axis X1 and the first axis X1, meaning the radius of rotation of the massage portion 30 increases to R4. At this point, the movement trajectory of the massage portion 30 is approximately a circle with a radius of R4, where R4 > R3. Since the area and radius have a square relationship, even a small increase in the radius of rotation of the massage portion 30 can lead to a significant increase in the massage range, further enhancing the massage effect.

[0045] In actual use, the massaged area may slightly indent under the action of the massage part 30. Correspondingly, the surrounding area of ​​the massaged area will bulge outward due to the indentation. The bowl-shaped part 52 also provides support and wrapping for the surrounding area of ​​the massaged area. The outward bulge of the massage part 30 relative to the bowl-shaped part 52 allows it to maintain contact with the indented massaged area, further enhancing the massage effect. In some embodiments, the inward indentation depth H of the bowl-shaped part 52 is 5-10 mm, specifically 6.5 mm, 7.8 mm, etc.; the diameter D of the open end 53 of the bowl-shaped part 52 is 20-50 mm, specifically 32 mm, 45 mm, etc.; the height L of the massage part 30 extending beyond the open end 53 of the bowl-shaped part 52 is less than 50 mm, specifically 18.5 mm, 35 mm, etc.

[0046] In this embodiment, a drive wheel 26 is fitted onto the second connecting end 24b of the drive shaft 24. The drive wheel 26 has a flat, circular structure and a larger radial dimension relative to the drive shaft 24, which can better drive the massage part 30 to rotate. During production, the drive shaft 24 and drive wheel 26 can be pre-assembled and then placed in a mold. The massage part 30 is then formed by injection molding or similar methods. After the massage part 30 is formed, the drive wheel 26 is integrally fixed, effectively improving the stability of the connection between the two. The massage part 30, especially the end where it connects to the bowl-shaped part 52, can have a clearance fit with the drive shaft 24, allowing the massage part 30 to generate sufficient deformation during rotation with the drive shaft 24, resulting in smoother rotation of the massage part 30.

[0047] Preferably, the drive wheel 26 has a neck 27, where the drive wheel 26 has its smallest inner diameter. The second connecting end 24b of the drive shaft 24 passes through the neck 27 and forms protrusions 25 on both axial sides of the neck 27, the outer diameter of the protrusions 25 being larger than the inner diameter of the neck 27. After assembly, the protrusions 25 provide a locking and positioning effect on the neck 27, preventing the drive wheel 26 from automatically detaching from the drive shaft 24 without external force, thus facilitating the subsequent molding and manufacturing of the outer shell and massage part 30. Of course, the drive wheel 26 and the drive shaft 24 can also be fixed in other ways, such as tight fit, snap-fit, or keying, and are not limited to specific embodiments.

[0048] In this embodiment, the massage unit 30 is disposed at the front end of the housing 10, and the drive mechanism 20 is disposed near the front end of the housing 10 to facilitate the connection between the drive mechanism 20 and the massage unit 30. To facilitate the arrangement of the reduction gearbox 22, the drive mechanism 20 also includes a reversing assembly 28 disposed between the reduction gearbox 22 and the drive shaft 24. In the illustrated embodiment, the reversing assembly 28 is a gear assembly, including a first gear 28a and a second gear 28b that mesh with each other. The first gear 28a is sleeved with the output shaft 229 of the reduction gearbox 22, and the second gear 28b is sleeved with the first connecting end 24a of the drive shaft 24, thereby realizing power transmission between the reduction gearbox 22 and the drive shaft 24.

[0049] In this embodiment, both the first gear 28a and the second gear 28b are bevel gears, which can change the direction of power transmission while simultaneously achieving power transmission. This allows the extension direction of the output shaft 229 of the reduction gearbox 22 to differ from the extension directions of the first connecting end 24a and the second connecting end 24b of the drive shaft 24. Specifically, the output shaft 229 can be perpendicular to the first connecting end 24a and inclined relative to the second connecting end 24b. In other embodiments, the reduction gearbox 22 can be arranged in different positions according to the spatial distribution within the housing 10, including at the tail end of the housing 10, thereby selecting matching reversing components, such as pulley assemblies, sprocket assemblies, worm gear assemblies, etc.

[0050] In some embodiments, the reduction gearbox 22 can also be directly connected to the drive shaft 24, omitting the commutation assembly 28. In this case, the output shaft 229 of the reduction gearbox 22 can extend outward from the side of the gearbox 225, and can be inclined or vertically arranged relative to the output shaft 222 of the motor 221, thus enabling the reduction gearbox 22 itself to change the power transmission direction. In this case, the gears 227 inside the gearbox 225 can be configured accordingly based on the change in the power transmission direction, and may include bevel gears, etc.

[0051] In this embodiment, the inner shell of the housing 10 forms a support frame 12 at the position corresponding to the drive mechanism 20, which is used to support the drive mechanism 20, especially the reduction gearbox 22, drive shaft 24, etc. In the illustrated embodiment, the support frame 12 is composed of two parts connected by snap-fit, and an internal space is formed to accommodate the drive mechanism 20. The first connecting end 24a of the drive shaft 24 is rotatably inserted into the bearing seat 14 of the support frame 12, and preferably a bearing 16 is provided in the bearing seat 14. The second connecting end 24b of the drive shaft 24 extends out of the support frame 12 and is integrally connected to the massage part 30. During production, the support frame 12 and the drive mechanism 20 are first assembled together, and then the outer shell and the massage part 30 are injection molded by overmolding, so that the drive mechanism 20 and the support frame 12 are integrally fixed in the outer shell.

[0052] In this embodiment, the tail end of the housing 10 serves as a handle, on which multiple buttons 54 are provided, including a power button and function keys, for easy grip and operation by the user. A control device, such as a control circuit board 56, is also provided in the tail end of the housing 10. The buttons 54, through the control circuit board 56, form a control circuit with the reduction gearbox 22, the vibration motor 40, etc. The user can select and adjust functions using the buttons 54, such as adjusting the speed and direction of the reduction gearbox 22, and adjusting the vibration frequency of the vibration motor 40. Preferably, a battery 58, preferably a rechargeable battery, is also provided in the tail end of the housing 10. The battery 58 is electrically connected to the control circuit board 56, serving as the power source for the entire massage device 100.

[0053] During use, the massage device of this utility model allows users to select different operating modes via button 54 on the handle, depending on the massaged area and the desired stimulation effect. For example, users can activate only the vibration motor 40 to drive the massage part 30 to vibrate at high frequency, achieving a certain massage effect through vibration; or, users can activate only the reduction gearbox 22 to drive the massage part 30 to rotate, producing a kneading massage effect through rotation; or, users can activate both the vibration motor 40 and the reduction gearbox 22 simultaneously, causing the massage part 30 to vibrate while rotating, experiencing a dual-effect massage effect. It is convenient to use and provides a good massage effect.

[0054] Figure 9-10 The following is another embodiment of the massage device of this application, which differs from the previous embodiment mainly in the massage part. In this embodiment, the housing 10 of the massage device 100 is generally a longitudinally elongated rod-shaped structure. The difference is that its tail end bends upward toward the middle and extends to form a branch 18. The end face of the branch 18 is concave to form a bowl-shaped part 52. The massage part 30 is disposed in the center of the bowl-shaped part 52 and extends outward through the open end 53 of the bowl-shaped part 52. In this embodiment, the open end 53 of the bowl-shaped part 52 is inclined at a certain angle toward the middle of the housing 10, and the part of the massage part 30 extending beyond the open end 53 is close to the middle of the housing 10.

[0055] A drive mechanism 20 is provided inside the housing 10. The drive mechanism 20 includes a reduction gearbox 22 and a drive rod 24. The drive rod 24 includes a first connecting end 24a and a second connecting end 24b arranged at an angle to each other. The first connecting end 24a is connected to the reduction gearbox 22, and the second connecting end 24b is connected to the massage part 30. Under the action of the reduction gearbox 22, the massage part 30 rotates around the first connecting end 24a with the second connecting end 24b, forming a roughly circular trajectory, which can create a kneading effect on a larger area of ​​the massaged area. Similarly, a vibrating element 40, such as a vibrating motor, is provided inside the massage part 30, so that the massage part 30 can produce dual stimulation to the massaged area.

[0056] In this embodiment, the front end of the housing 10 forms a massage end 32, and another vibrating element 42, such as a vibrating motor, is disposed inside the massage end 32. The rear end of the housing 10 serves as a handle for easy gripping by the user. The handle is equipped with buttons 54, etc., for controlling the operation of the gearbox 22 and the vibrating elements 40 and 42. When the massage device of this embodiment is in use, the massage part 30 and the massage end 32 can act on different parts of the human body, thereby achieving simultaneous massage of multiple parts and further enhancing the massage effect.

[0057] Figure 11-12 The image shows another embodiment of the massage device of this application, which differs from the previous embodiment mainly in the massage part. In this embodiment, the housing 10 of the massage device 100 is generally a longitudinally elongated rod-shaped structure, except that its central sidewall is concave to form a bowl-shaped portion 52. The massage part 30 is disposed in the center of the bowl-shaped portion 52 and extends outward through the open end 53 of the bowl-shaped portion 52. Preferably, the outer wall surface of the massage part 30 is provided with protrusions 34, which can be raised dots, raised strips, etc., to increase the stimulation of the massaged area.

[0058] A drive mechanism 20 is provided inside the housing 10. The drive mechanism 20 includes a reduction gearbox 22 and a drive rod 24. The drive rod 24 includes a first connecting end 24a and a second connecting end 24b arranged at an angle to each other. The first connecting end 24a is connected to the reduction gearbox 22, and the second connecting end 24b is connected to the massage part 30. Under the action of the reduction gearbox 22, the massage part 30 rotates around the first connecting end 24a at an appropriate speed along with the second connecting end 24b, forming a roughly circular trajectory, which can create a kneading effect on a larger area of ​​the massaged area.

[0059] In this embodiment, the front end of the housing 10 forms a massage end 32, and a vibrating element 42, such as a vibrating motor, is disposed within the massage end 32. The rear end of the housing 10 extends upward toward its central portion as a support 18, and a vibrating element 44, such as a vibrating motor, is disposed within the support 18. The rear end of the housing 10 serves as a handle for easy gripping by the user. The handle is equipped with buttons 54, etc., for controlling the operation of the gearbox 22 and the vibrating elements 42 and 44. When in use, the massage device of this embodiment can apply massage to three parts of the human body, respectively, achieving simultaneous massage of multiple parts.

[0060] The massage device 100 of this utility model creates a kneading effect on the user's massaged areas, such as the head, shoulders, neck, back, waist, and legs, through the rotation of the massage unit 30. At the same time, the vibration motor 40 inside the massage unit 30 can create a high-frequency vibration massage effect on the massaged areas. The superposition of these two different modes of action provides more effective stimulation to the massaged areas, resulting in a better massage effect.

[0061] It should be noted that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, such as combining different features in various embodiments, and these should all fall within the protection scope of the present invention.
