Korean Patent No. 10-1607526

SUMMARY OF THE INVENTION It is an object of the present invention to provide a massage device having a negative pressure generating structure.

Another object of the present invention is to provide a massage method preferred by the user by variously performing vibration intensity and vibration pattern of the massage device.

Another object of the present invention is to allow a user to carry a massage device to a user without being restricted by a location.

According to an aspect of the present invention, there is provided a massage device comprising: a case having a handle formed in a predetermined length and thickness; A driving unit provided in the case and provided with a pulse generator for generating a pulse; A controller for controlling a waveform of a pulse generated in the driving unit; And an oscillation unit connected to the driving unit and generating an oscillation by receiving an electric signal corresponding to a pulse from the pulse generator, wherein the oscillation unit generates a vibration by an electric signal corresponding to the pulse, And the massaging is performed by reciprocating movement in which contact and separation are repeated.

Here, the oscillating unit includes: a voice coil for receiving an electric signal corresponding to the pulse from the pulse generator; A permanent magnet surrounding the voice coil with an N pole and an S pole; And a massage plate coupled to an end of the voice coil to move together with the voice coil due to a magnetic force generated in the permanent magnet when an electric signal is applied thereto and a massage plate located outside the case and moving by being coupled with the vibration plate, The vibration plate is characterized in that the vibration pattern and the vibration intensity vary according to the waveform, amplitude, frequency, and period of the electric signal corresponding to the pulse applied to the voice coil in the pulse generator.

In addition, on the outer surface of the case, a key input unit as a command input means; And a display unit capable of grasping a vibration intensity and a vibration pattern according to an input of the key input unit. When the user operates the key input unit to select a pulse, the display unit displays a waveform, The amplitude, the frequency and the cycle are displayed.

The massaging plate and the diaphragm may be detachable from each other, and the diaphragm may have a different surface shape from the massaging plate.

The massage device according to the present invention has the following effects.

First, the intensity of the vibration can be controlled without using a motor. The massage device according to the present invention is provided with a negative pressure generating structure for generating vibration. That is, unlike a conventional massage device in which vibration is generated due to the performance of a motor, an electric signal corresponding to a pulse is applied to the voice coil, and a diaphragm and a massage plate interlocked with the voice coil and the voice coil, Moving up and down, the vibration is generated according to the movement, and massage is performed. At this time, the intensity of the vibration depends on the amplitude of the pulse applied to the voice coil. In other words, as the amplitude of the pulse applied to the voice coil is increased, the vibration width of the diaphragm is increased to increase the intensity of vibration, and conversely, as the amplitude of the pulse is smaller, the vibration width of the diaphragm becomes smaller, do. Therefore, the intensity of the vibration can be adjusted by adjusting the amplitude of the pulse applied to the voice coil without using a motor.

Second, the massage effect can be maximized. In the present invention, the waveform can be changed variously when an electric signal corresponding to a pulse is applied to the voice coil in the massage device. That is, the pulse can be applied to the voice coil in a spectrum of various waveforms such as a sine wave, a square wave, and a triangle wave, and the amplitude, frequency, and period of each waveform can be set differently. Therefore, the moving distance of the massage plate coupled to the diaphragm and the diaphragm increases according to the amplitude, and the massage plate and the diaphragm move faster or slower depending on the frequency. As a result, the vibration pattern of the massage plate coupled with the vibration plate is generated differently according to the electric signal corresponding to the pulse applied to the voice coil, so that the user can receive massage of the vibration pattern of his own preference, thereby maximizing the massage effect .

Third, the massage plate can be replaced if necessary. In the present invention, the rear surface of the massage plate and the diaphragm are formed to be detachable from each other. Accordingly, when a user's face is hit with a massage plate equipped with a rayon-made cosmetic pad, it is possible to expect the effect of allowing the cosmetic to be more easily impregnated on the face while performing the massage, and the massage plate can be replaced The massage device can perform massaging that applies acupressure. As described above, in the present invention, the massage device can be used by replacing the massage plate according to the user's needs.

Fourth, it is portable. The massage device according to the present invention can operate for a predetermined time without charging a separate power source when the charger is charged with power. Therefore, the massage device according to the present invention can massage the user while moving.

Fifth, only the local area can be massaged intensively. Since the massaging device according to the present invention has a volume and a size that can be easily carried, the user can selectively massage only the desired parts such as eyes, face, shoulders, arms, legs and massively.

<Configuration of Massage Device>

FIG. 2 is a perspective view exemplarily showing a massage device according to a preferred embodiment of the present invention, FIG. 3 is a sectional view schematically showing a cross section of the massage device shown in FIG. 2, and FIG. 4 is a cross- Fig. 2 is a block diagram for explaining the configuration of a massage device. Fig.

2 to 4, a massage device (hereinafter referred to as a 'massage device') based on a sound pressure generating structure according to an embodiment of the present invention includes a case 10, a driving part 20, a display part 30, a key input unit 40, a charging unit 50, a control unit 60, a power source unit 70, and a vibration unit 80.

The case 10 is formed in a substantially cylindrical shape so as to surround and protect the internal structures of the massage device, and a handle 11 is formed on one side with a predetermined thickness and length. The handle 11 is formed so that it is easy for the user to grasp and carry the massage device. For example, since the palm rest 12 is formed at the lowermost end of the handle 11 in a flat cylindrical shape, the user supports the user's hand when holding the handle 11, so that the user can easily grasp the massage device .

Although not shown, according to another preferred embodiment of the present invention, the handle 11 can be modified into various shapes to provide a stable grip feeling when the user grasps the handle 11. For example, a plurality of bends may be formed on the outer circumferential surface of one side of the handle so that the user can easily grip the handle.

That is, the user's fingers can be gripped on the curved handle side. Since the bent portion of the side of the handle supports one side of each finger, the user can feel comfortable in gripping the handle.

On the other hand, a handle (11) is additionally provided with a band (not shown) to support the user's hand. For example, a band having elasticity may be provided from any arbitrary point on the upper side of the case 10 or any arbitrary point on the upper side of the handle 11 to the upper end of the hand supporter 12. When the user grasps the handle 11, To support the user's hand. Accordingly, the user can use the massage device while grasping the massage device more stably. The structure for supporting the user's hand using the band is one example, and it is possible to use it if the structure supports the user's hand.

It is also possible to form a surface having a large frictional force, for example, a lattice pattern, a rough pattern or the like, on the handle 11 in a predetermined area. In this case, when the user grips the grip 11, the friction force is increased on the palm of the user, so that the grip 11 can be stably gripped without slipping easily.

The driving unit 20 includes a pulse power supply unit 21 and a pulse generator 22 which are disposed inside the case 10 to apply an electric signal to the vibrating unit 80 so as to generate vibration.

The pulse power supply unit 21 supplies power to enable the pulse generator 22 to operate.

The pulse generator 22 is electrically connected to the voice coil 81 of the vibration unit 80 and receives power from the pulse power supply unit 21 to apply an electric signal to the voice coil 81. In this pulse generator 22, pulses of various waveforms such as a sine wave, a square wave, and a triangle wave can be generated. Therefore, according to the present invention, the vibration pattern and the vibration intensity of the massage device can be generated differently by generating the waveform by varying the amplitude, the cycle, and the frequency of the respective waveforms.

The display unit 30 displays the current operating state of the massage device, and the vibration pattern and vibration intensity of the massage plate 87 of the vibration unit 80 are displayed. That is, the display unit 30 displays the waveform selected by the user and the amplitude, frequency, cycle, and the like, which are information on the waveform, and the waveform is transmitted from the pulse generator 22 to the vibration unit 80, The vibration pattern and vibration intensity of the massage performed when the voice coil 81 is applied to the voice coil 81 are displayed. Since the display unit 30 has a built-in LED and emits light, the user can easily grasp the current operating state of the massage device and turn the LED on / off according to the user's preference.

The key input unit 40 is provided on the outer side of the case 10 so as to operate the massage device according to the user's preference. The key input unit 40 is provided with a menu button, a selection button, a vertical movement button, and the like so as to set a vibration pattern and a vibration intensity of a massage preferred by the user. Accordingly, the user can confirm the amplitude, the frequency, and the cycle related to the waveform and the waveform currently selected by the user by operating the button of the key input unit 40 while confirming the information displayed on the display unit 30 with the naked eye.

Further, the approximate vibration pattern and vibration intensity of the massage to be performed by the user are displayed by selecting the waveform, amplitude, frequency, and cycle. Here, although the waveform selected by the user is basically the waveform set in the massage device, the user can newly set the waveform according to the selection of the amplitude, the frequency and the cycle, and the set waveform can be stored in the memory (not shown).

The charging unit 50 charges electric power required for the massage device from an external charger (not shown). In the present invention, after charging a certain amount of power to the massage device, the user can use the massage device while carrying the massage device. The charging of the charging unit 50 can be variously performed by a dedicated charger or a mobile phone charger.

The control unit 60 controls the driving unit 20 to generate a pulse according to the inputted command when the user executes the input using the key input unit 40 and controls the pulse generator 22 in the driving unit 20 . Also, the control unit 60 displays the information of the corresponding pulse on the display unit 30, and can compare pulse information. The controller 60 may be disposed in the form of a PCB substrate.

The power supply unit 70 supplies the electric power charged in the charging unit 50 to the inside of the massage device. The AC-DC converter is incorporated therein, and converts the DC power into DC power when supplied with electric power to supply power to the massaging device.

The vibration unit 80 generates vibrations in accordance with an electric signal applied from the driving unit 20 and includes the voice coil 81, the bobbin 82, the permanent magnet 83, the lower plate 84, the upper plate 85 A diaphragm 86, a massage plate 87, and a damper 89, as shown in Fig.

When the voice coil 81 is electrically connected to the pulse generator 22 and receives an electric signal corresponding to the pulse, a magnetic force is generated to receive the force.

The bobbin 82 is formed into a substantially cylindrical shape, and the voice coil 81 is wound on the outer side. When an electric signal corresponding to a pulse is applied to the voice coil 81 and a magnetic force is generated, the bobbin 82 moves together with the voice coil 81.

The permanent magnet 83 generates a magnetic force with the voice coil 81 when an electric signal is inputted to the voice coil 81. [ The N pole of the permanent magnet 83 is inserted into the bobbin 82 and the S pole is arranged at a certain distance from the voice coil 81 around the voice coil 81. [

The lower plate 84 is positioned at the lower end of the permanent magnet 83 to support the lower end of the permanent magnet 83.

The upper plate 85 is positioned at the upper end of the permanent magnet 83 to support the upper end of the permanent magnet 83. Accordingly, the permanent magnet 83 can be fixed inside the case 10 as it is supported by the lower plate 84 and the upper plate 85.

The diaphragm 86 is formed in a circular shape and is coupled to the end of the bobbin 82 outside the case 10 to move up and down together with the bobbin 82. The diaphragm 86 may be coupled to or disengaged from the massaging plate 87 by forming a detachable structure.

The massage plate 87 is formed in a circular shape and is manufactured so as to be detachable from the diaphragm 86. The massage plate 87 is combined with the diaphragm 86 and interlocked with the diaphragm 86 by the upward and downward movement of the bobbin 82, Accordingly, the massage is performed by periodically touching the skin of the user. The massage plate 87 is composed of a massage plate support 871 and a skin contact surface 872. The massage plate 87 is formed in such a manner that a skin contact surface 872 is put on the outer surface of the massage plate support 871, 871 and the skin contact surface 872 may be integrally formed.

The massage plate support portion 871 can be formed in a structure capable of being detached from the diaphragm 86, and FIG. 3 shows one example of such a detachment structure. That is, the massage plate holder 871 is made of a plastic material and can be deformed to some extent, and a plurality of latching rings 871a are formed at the lower end thereof. On the other hand, the diaphragm 86 has a plurality of latching grooves 86a.

The massage plate holding portion 871 is pressed against the diaphragm 86 after a part of the plurality of holding rings 871a of the massage plate holding portion 871 is first hooked to a part of the engagement grooves 86a of the plurality of diaphragm 86 The massage plate 87 and the diaphragm 86 can be engaged with each other since the remaining retaining rings 871a are deformed and inserted into the remaining retaining grooves 86a.

When the massage plate 87 and the diaphragm 86 are engaged and a force is applied from the side surface of the massage plate support 871a, the part of the engagement ring 871a caught by the engagement groove 86a in the direction of the force The hooks 871a which are deformed while being deformed can be released from the hooking grooves 86a and the remaining hooks 871a are released from the hooking grooves 86a, The diaphragm 86 can be disengaged.

As another example of the coupling structure of the massage plate 87 and the diaphragm 86, Fig. 5 illustrates a coupling structure of the massage device shown in Fig. 2 in a screw structure as an example of the detachment structure of the diaphragm and the massage plate And shows an exploded perspective view schematically shown.

As shown in FIG. 5, the massage plate holder 871 and the diaphragm 86 may be assembled together by screwing to form a desorption structure. That is, a central portion of the massage plate holder 871 is protruded to form a male screw portion 871b, and a central portion of the diaphragm 86 is formed with a female screw portion 86b in a groove shape.

In this state, when the male screw portion 871b of the massage plate support 871 and the female screw portion 86b of the diaphragm 86 are rotated in alignment with each other, the male screw portion 871b of the massage plate support portion 871 and the diaphragm 86 The diaphragm 86 and the massage plate 87 can be engaged with each other.

On the other hand, when the massage plate holder 871 is rotated in the opposite direction to the screw assembly, the engagement of the male screw portion 871b of the massage plate holder 871 and the female screw portion 86b of the diaphragm 86 is rotated, The diaphragm 86 and the massage plate 87 can be disengaged from each other.

The structure in which the massage plate 87 and the diaphragm 86 can be detached from each other can be variously implemented as well as the engagement structure and the screw engagement structure by the engagement ring 871 and the engagement groove 86a.

The skin contact surface 872 of the massage plate 87 may be replaced with a flat plate, a round plate, a concave plate or the like depending on the user's preference, and a plate having a plurality of protrusions formed on the surface thereof . The material of the skin contact surface 872 may be variously used, such as cotton, cotton, rayon, or synthetic fibers.

The damper 89 is disposed at the upper end of the upper plate 85 to guide the movement of the bobbin 82 when the bobbin 82 moves up and down, absorb shock, and control excessive vibration.

<Operation of the massage device>

FIG. 6 is a view schematically showing that a diaphragm is moved by a magnetic force generated between a permanent magnet and a voice coil when an electric signal is applied to the voice coil in the massage device shown in FIG. 2. FIG.

The operation of the massage device according to the embodiment of the present invention will be described with reference to FIG. 6, when an electric signal is first applied to the voice coil 81 from the pulse generator 22, the N pole of the permanent magnet 83 inserted into the bobbin 82 and the N pole of the voice coil 81 inserted into the bobbin 82, A magnetic force is generated between the S poles of the permanent magnets 83 disposed at a predetermined interval from the voice coil 81. As a result, a force is applied to the voice coil 81 based on the Fleming's left-hand rule. Therefore, the bobbin 82, on which the voice coil 81 and the voice coil 81 are wound, moves in a direction in which the force is applied.

In this case, since the electric signal is periodically applied with the positive and negative voltages as in the case of the sine wave, the voice coil 81 and the bobbin 82 are moved upward when seen in the drawing at the time of (+) voltage, -) voltage, the voice coil 81 and the bobbin 82 move downward. The diaphragm 86 coupled with the bobbin 82 and the massage plate 87 coupled with the diaphragm 86 are moved up to the positive voltage according to the period of the electric signal applied in the same manner as the bobbin 82 (-) voltage.

In this state, when the skin contact surface 872 of the massage plate 87 touches the user's skin, when the (+) voltage is applied due to the movement of the diaphragm 86, the skin contact surface 872 of the massage plate 87, The skin contact surface 872 of the massage plate 87 is separated from the skin of the user so that the skin contact surface 872 periodically touches the skin of the user, Therefore, the user is provided with the effect of receiving a massage.

7, when the user manipulates the massage device in the massage device shown in FIG. 2 to set the vibration pattern and the vibration intensity of the massage device, the corresponding information of the pulse applied to the voice coil 81 in the pulse generator 22 For example, schematically illustrating what is displayed on the display unit 30.

Referring to FIG. 7, a description will be given of how the user sets the vibration intensity and the vibration pattern while using the massage device. As shown in FIG. 7, the display unit 30 and the key input unit 40 are disposed adjacent to each other. Here, the key input unit 40 may include a menu button, a selection button, and an up and down button.

After the massage device according to the present invention is operated, when a menu button is pressed to set a vibration pattern and a vibration intensity of the massage device, the display unit 30 displays various kinds of waveforms of pulses and basic information Is displayed. This can be a waveform that is basically stored in a massaging device memory (not shown). Therefore, the user can basically select the stored waveform and receive the massage by the vibration pattern and vibration intensity when the corresponding waveform is applied in the massage device.

The user can also move the menu to generate a new waveform for the pulse and receive a massage with the vibration pattern and vibration intensity of the massage device operating with that waveform. That is, the user operates the key input unit 40 to enter a screen for generating a new waveform, and sets the spectrum, amplitude, frequency, and period of the waveform. At this time, after completing the setting of the waveform, the display unit 30 displays the approximate vibration pattern of the waveform and the degree of the vibration intensity. In the present invention, the criterion indicating the magnitude of the intensity with respect to the vibration pattern and the vibration intensity is shown by way of example, but the criterion can be displayed differently according to the practice.

The operation of the diaphragm 86 and the massage plate 87 when the electric signal corresponding to the pulse is applied to the voice coil 81 according to the information of the waveform for the pulse will be described.

For example, when a sine wave is applied to the voice coil 81, the (+) voltage and the (-) voltage are repeatedly applied to move the voice coil 81 and the bobbin 82 together. The voice coil 81 and the bobbin 82 move slowly at this time because the amplitude is gradually increased or decreased.

When the voice coil 81 and the bobbin 82 are moved away from the maximum and the minimum, the waveform rapidly increases or decreases. Therefore, the voice coil 81 and the bobbin 82 move faster than when they approach the maximum and the minimum. Accordingly, the diaphragm 86 and the massage plate 87 are moved in the same manner as the voice coil 81 and the bobbin 82. Accordingly, when a sinusoidal wave is applied to the voice coil 81, the massage plate 87 moves slowly when touching the user's skin to perform a massage of a soft pattern.

On the other hand, if a square wave is applied to the voice coil 81, the voice coil 81 and the bobbin 82 are repeatedly moved together due to the characteristics of the waveforms which are rapidly rising and falling, And the massage plate 87 also move rapidly. Therefore, when the rectangular wave is applied to the voice coil 81, the skin contact surface 872 of the massage plate 87 moves rapidly when touching the user's skin, so that the user performs a sudden pattern massage.

In addition, when a triangular wave is applied to the voice coil 81, the (+) voltage is constantly raised and lowered by the characteristic of the triangular wave, and the negative voltage is also raised and lowered constantly. Therefore, the voice coil 81 and the bobbin 82 move uniformly due to the characteristic of the waveform in which the triangular wave advances, so that the diaphragm 86 and the massage plate 87 also move constantly. Accordingly, when the triangular wave is applied to the voice coil 81, the skin contact surface 872 of the massage plate 87 moves smoothly when it touches the skin of the user, so that the user performs a massage with a soft pattern.

On the other hand, the greater the amplitude, the greater the diaphragm 86 and massaging plate 87 move. That is, when the (+) voltage is applied, the diaphragm 86 and the massage plate 87 are moved upward with respect to the basic position based on FIG. 6, and when the negative voltage is applied, The distance by which the plate 87 moves downward with respect to the base position is increased.

Accordingly, since the skin contact surface 872 is brought into contact with the user's skin when massage is applied from the negative (-) voltage to the positive (+) voltage, the (+) voltage at the position of the skin contact surface 872 The vibration intensity increases as the distance between the skin contact surfaces 872 increases, and the user can adjust the intensity of the massage by adjusting the magnitude of the amplitude in consideration of this.

In addition, the larger the frequency is, the more the diaphragm 86 and the massage plate 87 move sharply. That is, since the frequency is the number of repetitive movements in one cycle, when the frequency is high, the (+) voltage and the (-) voltage are alternately applied in an alternating manner, so that the diaphragm 86 and the massage plate 87 are rapidly moved The skin contact surface 872 also has a faster cycle of contact with the skin of the user, so that a rapid vibration pattern massage is performed.

Also, since the period means the time for repeating the waveform, if the period is long, the time required for the massage plate 87 to perform the vibration pattern once is increased.

Even if the vibration pattern and the vibration intensity of the waveform are not recognized as separate information according to the spectrum of the waveform according to the spectrum of the waveform, the user can intuitively understand the rough vibration pattern and vibration intensity of the massage . This will be described below.

FIG. 8 is a list of waveforms of pulses stored in the memory of the massage apparatus shown in FIG. 2 according to information of pulses set by the user in the memory of the massaging apparatus, and is displayed on the display unit. In order to allow the user to roughly compare the waveforms of the pulses, , Frequency and period are shown in the figure.

As shown in FIG. 8, when the user operates the key input unit 40, the stored waveforms are listed in the display unit 30 so that the user can intuitively perceive and compare the pattern and intensity of the massage, do. Further, according to the operating environment, it is possible to provide more accurate information to the user by adding references about the amplitude, the frequency and the cycle in correspondence with the respective waveforms.

For example, you can see if the amplitude of the waveforms is large or small, whether the frequency is large or small, and if the cycle is long or short. Further, the user refers to the influence of the amplitude, the frequency and the cycle of the massage device on the vibration intensity and the vibration pattern of the massage device, and when the massage is performed, it is easy to know which waveform is strong or weak in vibration intensity, have.

FIG. 9 is a diagram for explaining comparison in amplitude, frequency, and period of each of the waveforms when the user selects waveforms to compare two waveforms in the display unit shown in FIG. 8. FIG.

9, when the user operates the key input unit 40 in the menu for comparing pulses to select the waveforms 1 and 2, the control unit 60 compares the waveforms one-to-one, The comparison of the number of times and the short and long periods of the cycle are compared and displayed on the display unit 30. Therefore, the user can grasp the difference between the waveforms already stored and the newly set waveforms in detail, and can grasp whether any of the selected waveforms has a large or small vibration intensity and a sharp or smooth vibration pattern .

As described above, in the present invention, the spectra of various waveforms as well as the sine wave, the square wave, and the triangle wave are input to the voice coil 81, and the amplitude, the frequency and the cycle of each waveform are set, Massage that operates with a more varied vibration pattern and vibration intensity as the plate 87 moves can be performed.

Also, by comparing the set and stored waveforms in a list and comparing them, the user can roughly grasp the vibration intensity and the vibration pattern of the input of the corresponding waveform, and can confirm the numerical values by comparing the waveforms one by one.

<Replacement of massage plate and effect by various vibration patterns>

FIG. 10 is a view illustrating an example in which a skin contact surface of a massage plate is replaced in the massage device shown in FIG. 2 according to a preferred embodiment of the present invention. Referring to FIG. 10, another embodiment in which the skin contact surface 873 of the massage plate 87 is replaced and used will be described.

Another example of the skin contact surface 873 shown in Fig. 10 is a protrusion formed on the surface. The massage plate 87 is attached to the massage plate 87 in a state that the massage plate 87 is wrapped around the massage plate 873 or the massage plate 87 and the skin contact surface 873 are integrally formed. 87 and the diaphragm 86 can be replaced because the massage plate 87 can be engaged or disengaged from the diaphragm 86 by the detachment structure.

At this time, the detachment structure of the massage plate 87 and the diaphragm 86 may be structured such that they are interlocked with each other by the engagement groove 86a and the engagement ring 871a as in the above-described example, The male screw portion 871b formed on the diaphragm 871 and the female screw portion 86b formed on the diaphragm 86 may be screwed together. In the present invention, the massage plate 87 and the diaphragm 86 form a detachable structure in various ways as well as the above example, so that the skin contact surface 873 can be replaced.

As shown in FIG. 10, when the skin contact surface 873 having the protrusion on the surface thereof establishes a vibration pattern and vibration intensity capable of pressing the user's skin for a predetermined time and contacts the skin surface 873 of the user, the skin contact surface 873 The effect is that the pressure is applied by a plurality of protrusions formed on the base plate.

Among these, when massage is performed by contacting the skin contact surface 873 with the scalp, an effect of scalp massage for promoting hair occurs. That is, when the user sets the weak vibration intensity and the soft vibration pattern and brings the skin contact surface 873 to the scalp, the skin contact surface 873 smoothly contacts and separates repeatedly with respect to the scalp, 873) will act to tap the scalp lightly.

This action promotes blood circulation inside the scalp of the user, thereby circulating the heat accumulated in the scalp, thereby allowing the user to receive scalp massage to promote hair. Therefore, the user can easily perform the scalp massage only by bringing the massage device according to the present invention to the head.

Since the skin contact surface 872 can be replaced with various materials and shapes, and the movement of the skin contact surface 872 can be variously set by setting the vibration pattern and the vibration intensity, various effects can be expected.

In other words, in the present invention, the skin contact surface 872 does not vibrate in the form of rubbing the skin but repeats pressing and separating in contact with the skin with specific intensity and pattern. Accordingly, the vibration intensity and vibration pattern of the skin contact surface 872 can be set differently depending on which part of the user's body part is in contact with the skin contact surface 872.

First, when massage is performed around the eyes and the eyes, a massage plate 87 composed of a skin contact surface 872 made of a general cotton material can be coupled to the diaphragm 86 and used. If rubbed around the eyes, it may cause scratches on the cornea and diseases such as allergies or conjunctivitis. Therefore, it is not suitable for eyes and eyes around a massage device that simply vibrates left or right or up and down.

On the other hand, in the massage device according to the present invention, the skin contact surface 872 is set to move with a weak vibration intensity and a slow vibration pattern by setting a waveform having a small amplitude and a small frequency as described above, And the eyes are pressed lightly and repetitively, so that the massage device can easily massage the eyes to relieve the fatigue of the eyes.

As a result, the user can massage more conveniently than his / her hands around the eyes.

In addition, when the skin contact surface 872 is replaced with a cosmetic cotton such as rayon, it also has the effect of simultaneously promoting the massage performed on the face and the absorption of the cosmetic. Facial massage gives tension and elasticity to the skin, preventing the skin from sagging and wrinkles. Therefore, it is possible to set a waveform having a small amplitude and a large number of vibrations so that the skin contact surface 872 moves with a weak vibration intensity and a fast vibration pattern in a state in which cosmetics such as lotion, skin, facial water or lotion, etc. are impregnated on the skin contact surface 872 By setting, the massage device can perform a basic facial massage while tapping the face with the skin contact surface 872 repeatedly touching and separating from the face, and there can be obtained a side effect in which the cosmetic is impregnated on the face .

As a result, since the skin contact surface 872 is repeatedly contacted with and separated from the face, the massage device according to the present invention can perform the massage function on the face and facilitate the cosmetic to be easily absorbed on the face have.

In addition, when a strong massage is applied to the arms, legs and shoulders, a massaging plate composed of a hard skin contact surface 872 may be coupled to the diaphragm 86 for strong massage. That is, a waveform having a large amplitude and a large frequency is set so that a certain level of pressure can be rapidly applied to a user's arm or leg, and thus the skin contact surface 872 moves with a large vibration intensity and a fast vibration pattern, The user's arms and legs can be massaged repeatedly.

As a result, the skin contact surface 872 repeatedly comes into contact with the user's skin and is pressed and separated, thereby relieving the fatigue of the arms and legs by loosening the muscles in the arms and legs, and allowing the user to feel cool.

In addition, when a strong massage is applied to the soles of the feet, the same skin contact surface 872 as that used for massage on arms, legs and shoulders can be used, and the sole can be stimulated by setting the vibration intensity and the vibration pattern to the same.

The stimulation of the soles of the feet increases the blood flow due to the exercise of the motor nerves of the blood vessels. Accordingly, the fatigue accumulated in the body is relieved to improve the mood, and the brain is activated to improve the memory deceleration and the symptoms of dementia. It is also effective in improving knee pain and back pain in the elderly. This is not a simple vibration, but the effect is expressed by tapping the soles of the soles, the effect is increased by tapping the soles.

For this reason, the user can easily tap the sole using the massage device according to the present invention, thereby increasing the blood flow volume and expecting beneficial effects as the blood flow volume increases.

As described in these examples, the massage device according to the present invention can perform various types of massage by selectively replacing the skin contact surface 872.

In addition, in the massage device according to the present invention, the skin contact surface 872 is repeatedly contacted with and separated from the skin of the user, thereby performing massaging. In addition to performing weak and soft massage and strong massage in order to relieve fatigue, There is an additive effect that can promote absorption of cosmetics, and massages can also be provided to help promote health.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And additions should be considered as falling within the scope of the claims of the present invention.
