Description

Technical Field

[0001] This utility model relates to a massage device and a comb. Background Technology

[0002] Massage devices are widely used in various fields of soothing, relaxation, and health restoration. Most massage devices on the market currently use vibration, rolling, and rotation to simulate the effects of manual massage. Traditional massage devices typically rely on complex mechanical structures and multiple movement methods to produce a certain massage effect. However, these devices often have complex structures involving multiple moving parts and transmission systems, which makes them costly to manufacture, inconvenient to maintain, and may not be flexible or comfortable enough to operate.

[0003] Most existing massage devices use vibration or rotation to drive the massage area, but in some cases, the massage effect of these devices is not satisfactory, or due to their complex structure, it is difficult to achieve a more comfortable massage effect. Utility Model Content

[0004] The primary objective of this invention is to provide a massage device with a simple and reliable structure.

[0005] The second objective of this invention is to provide a comb with a simple and reliable structure.

[0006] The primary objective of this invention is achieved as follows:

[0007] A massage device includes a housing, a drive unit, a cylinder, and a swinging component. The outer wall of the cylinder has a wavy groove along its circumference. The cylinder is movably placed inside the housing. The drive unit is connected to the cylinder.

[0008] The oscillating components are movably spaced on the shell along the circumference of the cylinder. The head of the oscillating component extends outward through the shell to form a massage part, and the tail of the oscillating component is a control part. The control part abuts against the wave corresponding to the wave-shaped groove.

[0009] The drive device drives the cylinder to rotate, and the rotation of the cylinder causes the control part to slide along the wave-shaped groove. During the sliding process, the height of the control part changes, thereby causing the swinging component to swing. The massage part follows the swinging component to swing, producing a massage effect.

[0010] The rotating control unit of the cylinder slides along the wave-shaped groove, causing the control unit to change height, which in turn drives the swinging component to swing, and in turn drives the massage unit to swing steadily and regularly, providing a more stable and comfortable massage effect.

[0011] The height change of the control unit as it slides along the wave-shaped groove can adjust the movement trajectory of the swinging component, thereby effectively controlling the amplitude and speed of the massage unit's movement, achieving more precise massage actions, and improving the user's massage comfort and effect.

[0012] By employing a relatively simple gliding and swinging mechanism, this design reduces potential points of failure within the device by minimizing unnecessary moving parts and complex mechanical connections, thereby improving the device's lifespan and durability.

[0013] The primary objective of this utility model can also be achieved by the following technical measures:

[0014] Furthermore, the wave-shaped groove contains multiple waves, and the number of waves and the number of oscillating members are the same or in an integer ratio. When the control part enters the crest of a wave, the height of the control part rises, thereby causing the oscillating member to swing to one side. When the control part enters the trough of a wave, the height of the control part falls, thereby causing the oscillating member to swing to the other side.

[0015] The wave-shaped groove design incorporates multiple waves, the same number as or in integer proportion to the number of oscillating components, allowing the control part of each oscillating component to enter the crests or troughs of the waves in an orderly manner. Through this design, the oscillating movements of the components form a regular rhythm, making the massage process more comfortable and natural.

[0016] As the control unit enters the crest of the wave, its height increases, causing the oscillating component to swing to one side; as it enters the trough, its height decreases, causing the oscillating component to swing to the other side. This periodic change in height optimizes the amplitude and frequency of the oscillating component's movement, enhancing the kneading and massaging effect.

[0017] The wave-shaped groove design allows for adjustment of the number and shape of waves according to actual needs, thereby changing the oscillation frequency and amplitude of the oscillating component to adapt to different massage needs and provide a richer massage experience.

[0018] The oscillating component slides up and down with the crests and troughs of the wave-shaped groove, simulating the grasping and pressing motion of fingers on the scalp. This can deeply stimulate the scalp, promote blood circulation, help relax scalp muscles, and reduce fatigue.

[0019] The correspondence between the number of corrugated grooves and the number of oscillating components simplifies the device structure and reduces unnecessary parts. Optimized mechanical design ensures stable operation and improves product durability and reliability.

[0020] Because the wave-shaped groove guides the oscillating element to massage in an inward and outward oscillating manner, it avoids the hair tangling problems that can occur with traditional rotating movements. Whether you have long or short hair, you can safely and comfortably enjoy a massage experience.

[0021] The wave-shaped groove design enables rhythmic movement of the oscillating component through the natural guidance of the mechanical structure, eliminating the need for an additional complex control system, reducing the energy consumption of the drive device, and improving the product's energy efficiency ratio.

[0022] Through the coordinated design of the wave-shaped groove and the oscillating component, this massage device not only provides regular and comfortable massage movements, but also greatly enhances its applicability and user experience, giving it significant practical value and market competitiveness.

[0023] Furthermore, it also includes a shaft pin, the housing includes an annular seat, the surface of the annular seat is provided with connecting seats spaced apart along its circumference, the bottom of the connecting seats is open, and the side wall of the connecting seats is provided with a first shaft hole;

[0024] The swing member has a second shaft hole at its center. The swing member sits in the connecting seat. The massage part extends outward through the opening. The shaft pin passes through the first shaft hole and the second shaft hole. The swing member rotates around the shaft pin. When the control part is activated, the control part drives the swing member to swing around the shaft pin.

[0025] By incorporating a pivot pin and an annular seat, the oscillating component can be stably rotated around the pivot pin. As the center of rotation, the pivot pin effectively prevents the oscillating component from shifting or oscillating irregularly due to external forces or unbalanced movement, thus ensuring the stability and reliability of the massage device.

[0026] Because the movement of the oscillating component is more stable and precise, the oscillating motion of the massage unit is more ergonomic, providing a more comfortable massage experience. Users can feel a continuous and balanced massage effect, avoiding the abrupt or uneven massage movements that may occur with traditional massage devices.

[0027] Furthermore, the housing includes an annular seat, and connecting seats are spaced apart on the surface of the annular seat along its circumference. The bottom of the connecting seats is open, and the sidewall of the connecting seats has a first shaft hole.

[0028] The swing member has a fulcrum at its center. The swing member sits in the connecting seat. The massage part extends outward through the opening. The fulcrum abuts against the first shaft hole. The swing member rotates around the fulcrum. When the control part is activated, the control part drives the swing member to swing around the fulcrum.

[0029] The ring-shaped base design allows the oscillating component to rotate around a fulcrum, resulting in a more stable structure and smoother operation. Connecting seats are spaced circumferentially on the surface of the ring-shaped base, effectively distributing the position of the oscillating component and ensuring the uniformity and coverage of the massage device. The bottom opening of the connecting seats facilitates the installation of the oscillating component and ensures the massage head can pass through smoothly. A fulcrum is located at the center of the oscillating component, which rests against the first shaft hole, making the oscillation of the component more flexible and precise, thereby improving the performance and massage effect of the massage device.

[0030] Furthermore, the control unit drives the oscillating component to swing around the fulcrum through changes in the height of the wave-shaped groove. This, in turn, creates natural grasping or expanding movements in the massage unit, simulating the pressing and grasping effects of fingers, effectively relieving scalp fatigue and promoting blood circulation. This structural design not only ensures stable device operation but also reduces complexity and failure rate, extends product lifespan, and enhances the user experience.

[0031] Furthermore, the housing also includes a top cover and a waterproof soft protective sleeve, the annular seat is disposed inside the waterproof soft protective sleeve, the massage part extends outward through the waterproof soft protective sleeve, the cylinder sits inside the annular seat, and the top cover and the annular seat are fastened together.

[0032] By incorporating a waterproof, soft protective sleeve, the device's waterproof performance is effectively improved, preventing damage to the motor or drive mechanism caused by liquid entering the device and extending its service life. Simultaneously, the sleeve's soft material design ensures that the massage head does not cause additional friction or resistance when passing through it, guaranteeing the flexibility and smoothness of the massage head's movement.

[0033] The tight fit between the waterproof protective sleeve and the housing also prevents dust and foreign objects from entering, further enhancing the product's stability and safety. The annular seat, located within the protective sleeve, makes the device structure more compact while providing better fixation and support, ensuring precise and stable movement of the oscillating component. Furthermore, the snap-fit ​​design between the top cover and the annular seat facilitates assembly and disassembly, as well as cleaning and maintenance. The overall design fully considers practicality, durability, and user experience, making the device more adaptable to complex operating environments and enhancing product competitiveness.

[0034] The cylinder is located within the inner cavity of the annular seat, making the movement of the cylinder and the oscillating component more stable. The annular seat provides support and constraint, ensuring that the cylinder can rotate accurately and smoothly, avoiding instability in the massage effect due to structural looseness or imbalance.

[0035] Furthermore, the driving device includes a motor and a reducer. The reducer has a motor housing cavity, and the motor is placed inside the motor housing cavity. The input end of the reducer is connected to the output shaft of the motor. The upper cover has an opening corresponding to the motor location, and the conductive terminals of the motor are exposed outside the opening.

[0036] By introducing a combined design of a motor and a reducer, a smoother and more efficient drive can be achieved. The reducer effectively lowers the motor's output speed, making the entire device operate more stably.

[0037] The motor is housed within the motor housing of the reducer, and the top cover has an opening corresponding to the motor, facilitating easy installation and replacement. The motor's conductive terminals are exposed outside the opening, ensuring a more intuitive electrical connection and simplifying the connection between the motor and power supply, reducing cumbersome steps during installation.

[0038] Furthermore, the cylinder is a hollow cylinder with an open top, and the inner wall of the cylinder is provided with internal teeth;

[0039] The reducer is placed inside the cylinder, and the output end of the reducer meshes with the internal teeth of the cylinder.

[0040] By setting internal teeth on the inner wall of the cylinder and meshing the output end of the reducer with the internal teeth, a stronger and more stable mechanical connection is provided.

[0041] The meshing design between the internal gear teeth and the output end of the reducer provides direct and smooth power transmission, reduces energy loss, and improves overall drive efficiency. Because gear transmission has lower friction loss and a higher transmission ratio, it enables more efficient motion conversion, thereby improving the working efficiency of the massage device.

[0042] The internal gear design utilizes the internal space of the cylinder to directly integrate the power transmission system into the inner cavity, avoiding complex external connections and support components. Compared to traditional transmission methods, this design is more compact and efficient, reduces the use of external components, saves space, and makes the overall structure simpler and easier to assemble.

[0043] Furthermore, the massage section is provided with first comb teeth at intervals.

[0044] The placement of the first comb teeth at intervals in the massage area helps to distribute and evenly transmit massage pressure, avoiding excessive concentration of pressure in certain areas. This results in a more balanced massage process and enhances the massage effect. The comb teeth can simulate the grasping and kneading action of fingers, increasing the stimulation of muscles and making the massage more comfortable and effective.

[0045] The design of the first comb teeth increases the contact area between the massage area and the skin, providing a more delicate and gentle touch during massage and avoiding the discomfort of direct contact. The spacing of the comb teeth effectively controls the intensity and range of each massage, adapting to the needs of different users and improving massage comfort.

[0046] The first comb teeth allow the massage area to not only oscillate during the massage but also potentially create a slight sliding or grasping effect, thus simulating different types of massage techniques (such as pinching, pushing, and pulling). This diverse movement increases the variability and depth of the massage, providing a richer massage experience.

[0047] The spacing of the comb teeth allows for adjustment of the pressure and feel to suit different massage needs, making the device adaptable to a wider range of user requirements. For example, users can choose the appropriate massage intensity or experience mode according to their preferences.

[0048] The design of the first comb not only helps guide the massage area to glide evenly along the skin surface, but also allows for better control of the direction and intensity during the massage process, avoiding overly concentrated or uneven massage effects, and improving the precision and operability of the operation.

[0049] Furthermore, a second comb tooth is provided at the center of the bottom of the housing between the massage sections.

[0050] The second comb teeth enable the massage device to offer more diverse massage techniques and experiences, meeting the needs of different users. For example, during the massage, the comb teeth can work in conjunction with the movement of the oscillating component to provide timely deep massage, or to intensify the massage on a specific area, thus satisfying users' personalized needs for massage intensity and area selection.

[0051] The second objective of this utility model is achieved as follows:

[0052] A comb includes a comb body, a handle at the rear of the comb body, a receiving cavity at the front of the comb body, a power supply terminal provided on the comb body corresponding to the receiving cavity, a power supply built into the comb body, and the power supply and the power supply terminal being electrically connected.

[0053] The massage device is detachably installed in the accommodating cavity. The power supply terminal and the conductive terminal are electrically connected. The power supply terminal supplies power to the motor through the power supply terminal and the conductive terminal. The motor drives the cylinder to rotate through the reducer. The rotation of the cylinder drives the swinging component to swing.

[0054] By incorporating a built-in power source and a detachable massage mechanism, this comb not only offers traditional combing functionality but also provides a massage function. This design offers users a more convenient multi-functional product, combining combing and massage in one, meeting the needs of modern users for multi-functional tools.

[0055] The electrical connection design of the power supply and terminals ensures that the power supply can efficiently and stably provide the motor with the necessary power, ensuring smooth operation of the massage device. Users can easily activate the electric massage function by simply connecting the massage device to the comb body, without the need for an external power source or additional batteries, increasing ease of use.

[0056] The massage device is detachably housed within the comb body's cavity, making installation and removal easier. Users can easily remove or replace the massage device as needed for convenient cleaning, maintenance, or replacement of the oscillating components. The detachable design also enhances the flexibility of maintenance and use, increasing the product's adaptability.

[0057] The power supply provides power to the motor through power supply terminals and conductive terminals, and the motor then drives the cylinder to rotate through a reducer. This design allows the motor to stably drive the cylinder, which in turn drives the oscillating component to swing, ensuring smooth and stable power transmission during the massage process and enhancing the continuity and stability of the massage effect.

[0058] The combination of the motor and reducer allows the massage device's cylinder to rotate stably, thereby driving the oscillating components to perform even and effective massage movements. This design provides a deeper, more continuous, and stable massage effect, helping to relieve muscle fatigue, improve blood circulation, and increase comfort.

[0059] The beneficial effects of this utility model are as follows:

[0060] In this invention, the rotating drive control part of the cylinder slides along the wave-shaped groove, causing the control part to change height, thereby driving the swinging part to swing. The head (massage part) of the swinging part swings inward or outward with the movement of the control part, simulating the effect of finger grasping and producing a massage effect, thus providing a more stable and comfortable massage effect.

[0061] This invention avoids the risk of hair getting tangled in the comb teeth by the inward and outward swinging motion of the massage part relative to the shell. Therefore, it is suitable not only for users with short hair but also for users with long hair, thus expanding the applicability of the massage comb.

[0062] This invention employs a relatively simple gliding and swinging mechanism. By reducing unnecessary moving parts and complex mechanical connections, this design reduces potential failure points within the device, thereby improving the device's service life and durability.

[0063] This invention utilizes the internal space of the cylinder to directly integrate the power transmission system into the inner cavity, avoiding complex external connections and support components. Compared to traditional transmission methods, this design is more compact and efficient, reduces the use of external components, saves space, and makes the overall structure simpler and easier to assemble.

[0074] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0075] Implementation examples, in conjunction with Figures 1 to 10 As shown, a massage device includes a housing 1, a drive device 2, a cylinder 3 and a swinging component 4. The outer wall of the cylinder 3 has a wave-shaped groove 5 along its circumference. The entire wave-shaped groove 5 contains multiple waves 51. The cylinder 3 is movably placed inside the housing 1. The drive device 2 is connected to the cylinder 3.

[0076] The swinging member 4 is movably spaced on the housing 1 along the circumferential direction of the cylinder 3. The head of the swinging member 4 extends outward through the housing 1 to form a massage part 41. The tail of the swinging member 4 is a control part 42. The control part 42 abuts against the wave 51 corresponding to the wave-shaped groove 5.

[0077] The driving device 2 drives the cylinder 3 to rotate, and the rotation of the cylinder 3 causes the control part 42 to slide along the wave-shaped groove 5. The control part 42 changes height during the sliding process, thereby causing the swinging part 4 to swing. The massage part 41 follows the swinging part 4 to swing, producing a massage effect.

[0078] Furthermore, the wave-shaped groove 5 includes multiple waves 51, and the number of waves 51 and the number of swing members 4 are the same or in an integer ratio. When the control part 42 enters the crest of the wave 51, the height of the control part 42 rises, thereby causing the swing member 4 to swing to one side. When the control part 42 enters the trough of the wave 51, the height of the control part 42 falls, thereby causing the swing member 4 to swing to the other side.

[0079] Furthermore, it also includes a shaft pin. The housing 1 includes an annular seat 6, which is disposed in the inner cavity of the housing 1. Connecting seats 61 are spaced apart on the surface of the annular seat 6 along its circumferential direction. The bottom of the connecting seats 61 is open, and the side wall of the connecting seats 61 is provided with a first shaft hole 611.

[0080] The swing member 4 has a second shaft hole 43 at its center. The swing member 4 sits in the connecting seat 61. The massage part 41 extends outward through the opening. The shaft pin passes through the first shaft hole 611 and the second shaft hole 43. The swing member 4 rotates around the shaft pin. When the control part 42 is activated, the control part 42 drives the swing member 4 to swing around the shaft pin.

[0081] Furthermore, the housing 1 also includes an upper cover 11 and a waterproof soft protective sleeve 12. The annular seat 6 is disposed inside the waterproof soft protective sleeve 12. The massage part 41 extends outward through the waterproof soft protective sleeve 12. The cylindrical body 3 sits inside the annular seat 6. The upper cover 11 and the annular seat 6 are fastened together.

[0082] Furthermore, the drive device 2 includes a motor 21 and a reducer 22. The reducer 22 has a motor receiving cavity 221. The motor 21 is placed inside the motor receiving cavity 221. The input end of the reducer 22 is connected to the output shaft of the motor 21. The upper cover 11 is located at the motor 21 and has an opening 111. The conductive terminals 211 of the motor 21 are exposed outside the opening 111.

[0083] Furthermore, the cylinder 3 is a hollow cylinder with an open top, and the inner wall of the cylinder 3 is provided with internal teeth 31;

[0084] The reducer 22 is placed inside the cylinder 3, and the output end of the reducer 22 meshes with the internal teeth 31 of the cylinder 3.

[0085] Furthermore, the massage section 41 is provided with first comb teeth 411 at intervals.

[0086] Furthermore, a second comb tooth 412 is provided at the center of the bottom of the housing 1 located between the massage parts 41.

[0087] A comb includes a comb body, a handle at the rear of the comb body, a receiving cavity at the front of the comb body, a power supply terminal provided on the comb body corresponding to the receiving cavity, a power supply built into the comb body, and the power supply and the power supply terminal being electrically connected.

[0088] The massage device is detachably installed in the accommodating cavity. The power supply terminal and the conductive terminal 211 are electrically connected. The power supply terminal and the conductive terminal 211 supply power to the motor 21. The motor 21 drives the cylinder 3 to rotate through the reducer 22. The rotation of the cylinder 3 drives the swinging component 4 to swing.

[0089] How to install the massage device on a comb:

[0090] Align the massage device with the installation position inside the receiving cavity, and align the power supply terminal and conductive terminal 211 interface to lock the massage device inside the receiving cavity of the comb body, ensuring that the massage device will not loosen or shift during use.

[0091] How does a massage device work for head massage?

[0092] Drive unit 2 starts:

[0093] Press the switch or button to start the massage device on the comb. Power is supplied to the motor 21 through the power supply terminal, and the motor 21 starts and rotates.

[0094] The motor 21 reduces its speed through the reducer 22 and transmits power to the cylinder 3.

[0095] Rotation of cylinder 3 and movement of oscillating component 4:

[0096] Because the outer wall of the cylinder 3 is designed with a wave-shaped groove 5, the motor 21 drives the cylinder 3 to rotate, and the rotation of the cylinder 3 causes the swinging part 4 to slide along its circumference.

[0097] The head of the oscillating member 4 passes through the comb body and extends to form a massage section 41, which contacts the scalp. The tail of the oscillating member 4 is the control section 42, which slides along the wave-shaped groove 5 during the rotation of the cylinder 3, thereby producing a change in height.

[0098] Massage unit 41 oscillates with the oscillating component 4:

[0099] The oscillating motion of the massage section 41 is coordinated with the height change generated by the wave-shaped groove 5, thereby giving the massage section 41 a regular movement. This causes the head of the oscillating member 4 (massage section 41) to oscillate inward or outward with the movement of the control section 42. The massage section 41 simulates the effect of pinching fingers by contracting or expanding, thus producing a massage effect.

[0100] Because the massage section 41 swings inward and outward relative to the housing 1, the risk of hair getting tangled in the comb teeth is avoided. Therefore, it is suitable not only for users with short hair but also for users with long hair, thus expanding the applicability of the massage comb.

[0101] Functions of massage section 41:

[0102] The massage section 41, through its oscillating motion, can stimulate the scalp through gentle pushing and stretching, promoting blood circulation and relieving fatigue.

[0103] While oscillating, the massage section 41 may enhance the gripping and massage effect on the scalp through the design of the comb teeth, thereby bringing a more comfortable and deeper massage experience.

[0104] The duration of electric massage:

[0105] The coordination between motor 21 and reducer 22 ensures the stability and continuity of the massage device. Throughout the massage process, motor 21 continuously provides power, enabling the massage device to maintain a certain rotation and oscillation speed, thereby continuously producing a massage effect.

[0106] Due to the device's stability and even oscillation, the massage device can provide a continuous and comfortable massage to the head, relieving tension and stress.

[0107] Comfort and deep effects:

[0108] The design of the comb body and the oscillating motion of the massage section 41 make the massage not just a superficial combing, but also a deep massage effect. With this electric massage device, users can enjoy a highly effective scalp massage while combing their hair, effectively relieving discomfort caused by stress, tension, or headaches.

[0109] Disassembly and convenience:

[0110] Because the massage device can be easily disassembled and installed, users can easily remove it when the massage function is not needed and use only the traditional combing function, which increases the product's applicability and convenience.

[0111] In other embodiments, the housing 1 further includes an annular seat 6, on the surface of the annular seat 6 are spaced connecting seats 61 along its circumference, the bottom of the connecting seats 61 is open, and the sidewall of the connecting seats 61 is provided with a first shaft hole 611.

[0112] The swing member 4 has a fulcrum at its center. The swing member 4 sits in the connecting seat 61. The massage part 41 extends outward through the opening. The fulcrum abuts against the first shaft hole 611. The swing member 4 rotates around the fulcrum. When the control part 42 is activated, the control part 42 drives the swing member 4 to swing around the fulcrum.
