Massage device and control method {MASSAGE DEVICE AND CONTROL METHOD OF THE SAME}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage device and a control method thereof, and to a massage device and a control method for relieving fatigue of a whole body by generating low frequency vibration and high frequency vibration.

Massage is to tap or press a part of the body to a certain pressure to release the muscles and smooth blood circulation. In addition to the user directly presses the body with hands or feet, acupressure or massager is operated manually. There is this.

An automatic massage device uses electric energy to operate a motor or solenoid to massage a part of the body with periodic pressing force. However, since most massagers only generate vibrations of a certain frequency, they have a structure that is difficult to operate in various modes such as delivering vibration force deep in the skin by increasing the frequency or massaging with strong force by increasing the amplitude.

The present invention has been made to improve the problems and to provide a structure that can generate various types of vibration waves, such as low frequency vibration, high frequency vibration, as well as a superimposed vibration wave to increase the massage effect and to provide various and active control methods. .

The technical problem to be achieved by the present invention is not limited to the technical problem mentioned above, and other technical problems not mentioned above may be clearly understood by those skilled in the art from the following description. will be.

Massage device of the present invention, the massage head for generating a vibration for the massage, and a vibration unit having a magnet connected to the massage head; A fixing part including a coil exerting an electromagnetic force on the magnet and a core on which the coil is wound; It includes.

In the control method of the massage device of the present invention, a magnet is connected to a massage head which is vibrated in a first direction which is a direction in which the body is pressed and a second direction which is in the opposite direction, and the magnet is divided into magnetic poles along the first direction. A coil is wound around a recess of the core inserted into the magnet, and when the power is applied to the coil, the core is divided into one side and the other side in the first direction with respect to the recessed part. Moving the massage head along the first direction by applying a first power source to the coil; Vibrating the massage head at a second frequency by applying a second power source to the coil; Returning the massage head along the second direction by applying a third power source to the coil; Repeat.

According to the present invention, the use of various modes of excellent adaptability to the massage effect is excellent and suitable for the user of various symptoms by simultaneously generating a low-frequency vibration to massage muscle effect and a high-frequency vibration to penetrate deep into the muscle It can provide, has the advantages of good electrical efficiency, easy to manufacture, low noise and excellent durability.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this process, the size or shape of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms that are specifically defined in consideration of the configuration and operation of the present invention may vary depending on the intention or custom of the user or operator. Definitions of these terms should be made based on the contents throughout the specification.

In general, considering the constant energy conditions in the device of the same power, there is a property that the amplitude during high frequency vibration is reduced and the amplitude during low frequency vibration is increased. Therefore, the high-frequency massager is a massage effect to massage the human body is reduced and excellent treatment or cleaning effect by the high-frequency vibration, low-frequency massager can be seen to increase the massage effect, although the treatment or cleaning effect is reduced.

However, since the massage device of the present invention has a structure that is easy to control in the form of superposition of high frequency vibration as well as low frequency, low frequency vibration performance for the massage effect, as well as high frequency for penetrating deep into the human body or treating or cleaning effect It is a multipurpose massage device that can secure vibration performance at the same time.

Furthermore, since the structure can be used in combination with a plurality of vibrating parts, it is possible to increase the vibration frequency and amplitude if necessary, and at the same time can also have various effects of increasing the force (torque) corresponding to the amplitude.

That is, in the present invention, the signal applied to the coil is a high frequency (ultrasound) signal for increasing the penetration force and a low frequency signal (sine wave or square wave) that can feel the vibration for massage, and modulates the signal to relax the muscles that can be felt by the skin. Ultrasonic waves with excellent effect (massage) and penetration can be generated at the same time, so that the massage effect that relaxes muscles and the ultrasound (therapist) effect that deeply penetrates the skin can be produced simultaneously.

First, the ultrasonic cleaning effect will be described. The frequency used in the ultrasonic cleaner mainly uses 28 kHz (28,000 times / 1 second), 40 kHz (40,000 times / 1 second). The mechanism of the ultrasonic cavitation generated when the ultrasonic wave is irradiated into water is a bubble generated by three stages: nucleation, numerous bubbles, and explosive burst of sufficiently grown bubbles. When the internal temperature and pressure reach 4,500 ° C and several hundred atmospheres, and the fully grown bubbles are broken, a shock wave with a local temperature of about 1,500 ° C and a pressure of several hundred atmospheres is generated.

The shock waves generated in many of these small bubbles clean the fine parts out of reach of human hands, and the effect is amazing. In order to examine the skin cleansing effect of the ultrasonic beauty device, when the ultrasonic wave is applied to the metal head of the ultrasonic therapy device by putting water in the beaker, small bubbles (water drops) are generated. It is proved by the fact that the same occurs in this ultrasonic beauty machine.

Next, in the present invention, a heating plate or a member generating frictional heat may be installed, which has a thermal effect.

There have been many devices that utilize the thermal effect in conventional treatment devices. However, the conventional heating apparatus has a limitation that the thermal effect is transmitted only to the skin surface. However, the ultrasonic vibration generated in the present invention may apply a physical force deep into the skin, and at this time, the molecular heat generated by the vibration causes vibration heat to be penetrated deeply into the skin due to the friction caused by the ultrasonic wave, and the member vibrates ultrasonically. Is installed symmetrically, or additionally a heat source is added when additionally generating a heating plate or a member that generates friction heat.

For example, non-electric piezoelectric ceramics can vibrate millions of hertz. At this time, the thermal effect can be obtained by the frictional heat generated by the high-speed vibration millions of times per second. This can be compared to rubbing a wooden stick to make a fire. Massage the face during skin care is to give a stimulation by such friction.

In other words, the energy conversion mechanism of ultrasonic waves can be summarized as electrical energy is converted into physical kinetic energy and converted back into thermal energy. This thermal energy is a thermal effect by the ultrasonic waves. It should be recognized that ultrasound is more important than the effect on the surface of the skin.

The temperature of skin tissue is about 32 degreeC normally. According to the experiment, when the ultrasonic wave of 1MHz band was applied for 10 minutes when the ultrasonic wave was not able to endure heat, the ultrasonic power output was 0.04 ℃ at 0.5wt / ㎠ and 1.0wt / ㎠ At 0.16 ° C, 1.5wt / cm 2, the temperature increased to 0.3 ° C and 2.0wt / cm 2 to 0.38 ° C.

The coil 210 is a portion that generates an electromagnetic force by facing the magnet 120, and the core 220 is a portion where the coil 210 is wound. The core 220 has a depression 221 in which the coil 210 is wound at the center, and polarity of one side and the other side is divided based on the depression 221 when power is applied to the coil 210.

For example, when the first power source P1 in the positive direction is applied to the coil 210 and the upper side of the recess 221 has the magnetic pole of N pole, the lower side of the recess 221 has the magnetic pole of S pole. . When the second power source P2 in the reverse direction is applied to the coil 210, the upper portion of the recessed portion 221 has a magnetic pole of S pole, and the lower side of the recessed portion 221 has a magnetic pole of N pole.

This is to ensure mechanical stability during the movement of the vibration unit 100. In addition, lubrication or frictional heat may be generated.

In an embodiment, the massage head 110 is connected to the heat generating secondary coil 240 and the heat generating secondary coil 240 that surround the coil 210 to increase the heating effect and generate heat by electromagnetic induction. A heating plate 230 for heating is provided.

In order to increase the therapeutic effect, the heating plate 230 may be coated with a far infrared ceramic.

The massage device of the present invention preferably includes at least one of the housing 10, the central shaft 150, the sleeve 155, the friction plate 290, and the cushion ring 20.

The housing 10 is to be the main body of the massage device is connected to the fixing part 200 to support the load and becomes a base when vibration is generated. The central axis 150 protrudes inward of the massage head 110 and is movably inserted into the central portion 225 of the core 220. The sleeve 155 is a central axis 225 of the central axis 150 and the core 220 for lubrication during abrasion prevention or vibration movement of the central axis 150 of the massage head 110 or the central portion 225 of the core 220. It is a durable member inserted between). The cushion ring 20 is a flexible member made of an elastic material that supports the vibrator 100 to be movable by connecting the vibrator 100 and the housing 10.

The friction plate 290 is disposed adjacent to the core 220 (but not limited thereto), and is fixed to the fixed part 200 and in contact with the vibrator 100, and generates contact frictional heat according to the vibration of the vibrator 100. Back to any embodiment), friction head 110, magnet 120 or sleeve 155 to generate frictional heat. This is a member that heats the massage head 110 to increase the thermal effect.

4 shows a control method of the massage device of the present invention. Referring to this, reference numeral 1 denotes an initial position, reference numeral 2 denotes a state in which the vibrator 100 is moving along the first direction, and reference numeral 6 denotes a vibrator 100. The reference numeral 7 denotes a state in which the vibrator 100 is moving along the second direction opposite to the first direction, and the reference numeral 8 denotes a state in which the vibration unit 100 is vibrated at a high frequency in a state completely moved in the first direction. ) Denotes a state in which the vibrator 100 is completely moved along the second direction and returned to the position of the reference numeral 1 which is an initial state.

It is the control of the present invention that the vibration unit 100 sequentially repeats the positions of the reference numerals (1) (2) (6) (7) (8) by applying the power waveform of the coil 210 as shown. It is a way.

That is, in the control method of the present invention, the reference head 2 and the coil 210 are moved to the massage head 110 in the first direction by applying the first power source P1 to the coil 210. By applying the second power source (P2) to the reference numeral (6) which is a step of vibrating the massage head 110 at the second frequency, and applying the third power source (P3) to the coil 210 to remove the massage head (110) Reference numeral 7 is repeated, which is a step of returning along the second direction, which is the reverse direction of the one direction. Reference numerals 1 and 8 are initial positions.

The first power source P1 is a square wave power source of a first frequency having a first period, and the third power source P3 is a square wave power source of a third frequency having a third period and is inverted with each other. Here, the first frequency and the third frequency may be the same as well as different in some cases. Since the first frequency and the third frequency are relatively low frequency compared to the second frequency, the first frequency and the third frequency correspond to the low frequency vibration component, not the high frequency vibration, and are vibration components for the massage effect.

Meanwhile, the massage head 110 is vibrated at the second frequency by applying the second power source P2 to the coil 210 to generate a high frequency vibration component. Here, the second frequency is the inverse of the reference symbol t2. This is shown at 6. In this case, the second power source is preferably a sinusoidal or square wave power source that alternately repeats a positive sign and a negative sign to generate a sufficient high frequency vibration component. Here, the positive sign power is in phase and the negative sign power is in phase.

Separately, a high frequency vibration source may be provided. This is to superimpose the high frequency vibration component on the first power source P1 and the third power source P3.

That is, by time-dividing the first power source P1 so that the high frequency is superimposed on the first frequency, the massage head 110 may be vibrated in a form in which the high frequency is overlapped with the first frequency as the basic base. Here, the first frequency is the inverse of reference numeral t1, and the high frequency superimposed thereon is the inverse of reference numeral t1 '.

In addition, by time-dividing the third power source P3 so that the higher frequency is superimposed on the third frequency, the massage head 110 may be vibrated in a form in which the high frequency is higher than that of the massage head 110 as a basic base. Here, the third frequency is the inverse of the reference symbol t3, and the high frequency superimposed thereon is the inverse of the reference symbol t3 '. This improves power efficiency and can also reduce the size of the device.
