Description

[0002] MASSAGE DEVICE USING MIDIUM FREQUENCY WAVE [0003]

More particularly, the present invention relates to a mid-frequency massager, and more particularly, to a massage device using a mid-frequency wave to impart a strong stimulus to the skin surface and skin, The two heads can be pivoted to easily contact the bending part of the human body and each head has the function of skin adsorption and conductive gel injection, And more particularly to a mid-frequency massager which can be used.

The subcutaneous fat of the human body is composed of fat granules surrounded by cellulite. However, the fat surrounding the cellulite is not easily broken down by exercise. This is because the cellulite layer does not transfer lipase.

On the other hand, sound pressure, ultrasound, middle and low frequency, and far infrared rays have been proved to be effective in removing subcutaneous fat and preventing skin aging through long-term studies.

Among these, medium and low frequency (medium and low frequency) refers to electromagnetic waves with low frequency, stimulates the skin of the human body with electric current, and produces an intended skin cosmetic effect. In other words, by flowing a weak current with a constant rhythm to the skin, it helps to relieve fatigue and relieve fatigue, relieve muscle pain, and improve blood circulation. More specifically, low frequency It has been reported that elasticity of collagen and elastin, which is caused by blood circulation promotion and massage effect, is increased due to repetition of contraction of muscles, thereby creating a resilient skin. Collagen and elastin are fibers that act like a rubber band that regulates the elasticity of the skin. The skin, which is connected to each other like a net, can be regarded as a skin without wrinkles and no sagging of the flesh. . In other words, it is known that low-frequency stimulation eliminates the wrinkles of the human skin and has the effect of refreshing the body line with elasticity.

Conventionally, a variety of subcutaneous fat removal and exercise devices have been developed by applying the above-described effects of the medium and low frequency.

A conventional exercise machine for removing subcutaneous fat and the like will be described in more detail.

Conventional exercise machines have a method of removing fat by mechanical exercise and a method of removing fat by ultrasonic waves or electric stimulation. For example, Patent No. 10-1117612 discloses a mechanical exercise type fat removal apparatus. Examples of the fat removal apparatus using the ultrasonic stimulation system and electric stimulation system include Registration No. 10-0611142 and Registered Utility Model No. 20 -0353660.

In the case of the electric stimulation method, a frequency of 1,000 Hz or less is classified as a low frequency, a frequency of 1,000 to 4,500 Hz is classified as a mid frequency, and a frequency higher than 1,000 Hz is classified as a high frequency.

Generally, the low frequency used for medical use is similar to bioelectrical electricity flowing in the human body, and it stimulates muscles and nerves and functions to mitigate symptoms such as muscle paralysis, pain and fatigue.

Typical low-frequency-related products typically use about 10 to 200 Hz. These frequencies can be used to tense and stimulate the muscles, but it is difficult to exercise to remove abdominal fat.

In order to remove the abdominal fat, the human body must equip the muscle with the electric stimulation to consume the energy due to the muscle movement. However, in the case of the general low-frequency product, only the contraction of the muscle due to the electric stimulation occurs and energy consumption occurs I can not say.

Generally speaking, the higher the frequency, the greater the depth of electrical stimulation applied to the skin. In the case of low frequency, stimulation is applied to the surface of the skin. In the case of the medium frequency, the skin penetrates from 2 cm to 3 cm. In the case of high frequency, the skin penetrates more deeply, but heat is generated by the electrical resistance of the human body. High-frequency deep-sea heat products using these heat-generating effects are also shown.

In recent years, a medium frequency abdominal fat remover (Patent No. 10-1591736) has been developed for the purpose of removing abdominal fat using a medium frequency. The device is provided with a handle on the upper side and electrode pads in the bottom of which the electric stimulation is applied in the cross direction. The user moves the stimulation position by moving the device by holding the handle, and the stimulation is performed.

However, in such a conventional mid-frequency abdominal fat remover, a pair of electrode pads inducing a beating phenomenon are provided together on one bottom surface, and a beating phenomenon occurs in the vicinity of the skin layer, so it is difficult to exercise the muscle layer and the fat layer below the skin layer.

In addition, since the conventional mid-frequency abdominal fat remover has four electrode pads disposed on the bottom of a hard plate, it can be used only in the abdominal region of the front having a relatively flat outer surface, and it is difficult to use the electrode pad in the bent region of the human body.

In addition, the conventional mid-frequency abdominal fat remover can be driven only when all the electrode pads are brought into contact with the skin of the human body. To this end, users should pay special attention to prevent the electrode pads from falling off the skin, It has a disadvantage that the usability is very low because a large amount of force must be continuously applied to the device so that the contact of the electrode pads is maintained. In addition, since the conductive gel must be applied to the skin every time the device is moved to another site, there is a problem that it is inconvenient to use.

In order to solve the above-mentioned problems, it is an object of the present invention to provide a mid-frequency massage device capable of applying a strong stimulus to the surface of the skin and the inside of the skin using the mid-frequency to give a muscle-

Another object of the present invention is to provide a mid-frequency massager capable of stimulating a wider area by contacting the user's skin through two separate heads.

It is another object of the present invention to provide a middle-frequency massage device in which two heads can be pivoted so that a user can easily contact a bending part of a human body.

It is another object of the present invention to provide a mid-frequency massager in which each head has a function of skin adsorption and conductive gel injection so that it can be easily used.

According to the present invention, a handle is formed in a bar shape so as to be gripped by a user's hand, and a user interface unit is formed on an upper surface of one end portion. A first head part and a second head part connected to both ends of the handle and having a plurality of electrode pads disposed on the bottom surface to energize a mid-frequency signal to the human body; A voltage applying unit configured to generate a direct-current stimulation voltage; A frequency adjusting unit for adjusting a voltage output from the voltage applying unit to adjust an output stimulus intensity of the mid-frequency; A frequency generator for outputting a medium frequency signal with the intensity adjusted by the frequency adjusting unit and transmitting the medium frequency signal to the electrode pads; A control unit for controlling operations of the voltage application unit, the frequency adjustment unit, and the frequency generation unit according to a user operation through the input unit of the user interface unit and outputting the operation details of each sub-configuration to the display unit of the user interface unit; And a hinge part formed at one end of the housing, the hinge part being formed at the other end of the housing, the hinge part being formed in the housing, And a fastening groove is formed on an outer side of the fastening groove, so that the fastening groove is formed on the outer side of the fastening groove, The inner wall and the hinge portion are coupled with each other in a state where the engaging clip is interposed in the pivotal groove of the hinge portion to enable the pivotal movement of the housing, and the bottom surface of the first and second head portions A suction wall is provided along the outer periphery of the electrode pads and a flow port for sucking air is formed on the bottom surfaces of the first and second head portions , One end of a circulation line for air transmission is connected to the circulation port, and the other end of the circulation line is connected to a fixed base fixed to the inside of the handle, and one side of the circulation line is protruded to the outside And an elastic member having elasticity is interposed between the fixing base and the button so that the user can press the flexible base with the elastic member. When the button is pushed while the handle is grasped, the expansion joint pipe is contracted. When the force pressing the button is released, the expansion joint pipe is inflated and sucked air through the distribution line to adhere the suction wall to the skin. A plurality of injection ports for discharging the conductive gel are formed on the bottom surfaces of the head part and the second head part, One end of the injection line for delivering the gel is connected and the other end of the injection line is connected to a fixed dome fixed to a mounting base inside the handle, and a pressing member, which is contracted and relaxed in accordance with the pressing force, And the inner space formed by the fixed dome and the pressing member is filled with the conductive gel. When the user holds the handle, when the button is pressed, the corresponding button is moved to the inside of the handle to push up the pressing member to shrink the pressing member, And discharging the conductive gel through the injection line to discharge the conductive gel through the injection port of the first head part and the second head part.

Preferably, the first head part and the second head part are spaced apart from each other, and one of the first and second electrode pads of the first head part and the third and fourth electrode pads of the second head part Wherein one of the electrodes forms a different electrode, and a medium frequency signal is passed through the human body.

Preferably, the pressing member is formed in a dome shape and is made of any one of rubber, plastic, and silicone having ductility.

The mid-frequency massager according to the present invention uses a mid-frequency wave to impart a strong stimulus to the surface of the skin and the inside of the skin to give a muscle exercise effect and a lipolysis effect.

In addition, since the conventional mid-frequency abdominal fat remover can only stimulate a narrow area because the bottom surface where the electrode pads are gathered is wide, it is necessary to stimulate the abdomen fat for a certain period of time so that the abdominal fat removal effect can be obtained. In order to avoid the great hassle and time consuming. And a pair of electrode pads for inducing a beating phenomenon are provided together on one bottom surface, and a beating phenomenon occurs in the vicinity of the skin layer, so it is difficult to exercise the muscle layer and the fat layer below the skin layer. Alternatively, the mid-frequency massager according to the present invention may contact the user's skin through two separate heads, thereby stimulating a wider area.

In addition, since the conventional mid-frequency abdominal fat remover has four electrode pads disposed on the bottom of a hard plate, it can be used only in the abdominal region of the front having a relatively flat outer surface, and it is difficult to use the electrode pad in the bent region of the human body. In contrast, according to the present invention, since the two heads can be rotated, it is possible to easily contact the bending part of the human body.

In addition, the conventional medium frequency abdominal fat remover can only be driven if all the electrode pads are brought into contact with the skin of the human body. For this purpose, users should pay special attention to prevent the electrode pads from falling off the skin during use. It has a disadvantage in that the usability is very low because a large amount of force must be continuously applied to the device so that the contact of the electrode pads is maintained. In addition, since the conductive gel must be applied to the skin every time the device is moved to another site, there is a problem that it is inconvenient to use. In contrast, the mid-frequency massager according to the present invention has an effect that each of the heads has a skin adsorption function and a conductive gel injection function so that the head can be easily used.

1 is a perspective view illustrating a mid-frequency massager according to an embodiment of the present invention.

Referring to FIG. 1, a middle-frequency massage device according to an embodiment of the present invention includes a handle 100 formed in an elongated bar shape so as to be gripped by a user's hand, And a first head unit 200 and a second head unit 300, in which a plurality of electrode pads are disposed.

The handle 100 is formed in an elongated bar shape and is formed so that an intermediate portion is bent so as to be easily grasped by a user. With such an ergonomic design, the middle part of the handle 100 is protruded in a direction opposite to the first head part 200 and the second head part 300 so that the entire handle 100 is bent, The user's finger is naturally positioned at the depressed portion while grasping the handle 100, so that the user can easily move in the grip and grip state.

On the upper surface of one end of the handle 100, a user interface unit 110 is formed. The user interface unit 110 includes an input unit 111 in the form of a push button for the user to operate the device and a display unit 112 for outputting the operation information of the device.

The first head unit 200 and the second head unit 300 are connected to both ends of the handle 100. The first and second head units 200 and 300 are connected to both ends of the handle 100, . Particularly, since the first head 200 and the second head 300 are not directly connected to each other and are spaced apart from each other by a predetermined distance, the first head 200 and the second head 300 can stimulate a wider range than a conventional single head.

2, the construction of a mid-frequency massager according to an embodiment of the present invention will be described in more detail.

The mid-frequency massager according to the embodiment of the present invention includes a voltage applying unit 130 for generating a direct-current stimulating voltage, a frequency adjusting unit 130 for adjusting a voltage output from the voltage applying unit 130, A frequency generator 150 for outputting an intermediate frequency signal having an intensity adjusted by the frequency adjuster 140 and a plurality of electrodes for receiving a mid frequency signal from the frequency generator 150, The frequency adjusting unit 140 and the frequency generating unit 150 according to a user operation through the pads 210, 220, 310 and 320 and the input unit 111 of the user interface unit 110, And a controller 120 for controlling the operation of each sub-component and outputting the operation of each sub-component to the display unit 112 of the user interface unit 110. [

Each of the subassemblies configured in the mid-frequency massager according to the present embodiment will be described in turn according to the operation order.

The user operates the input unit 111 while watching the output contents of the display unit 112 for the operation of the medium frequency massager and controls the bottom surface of the two side head units 200 and 300 of the middle frequency wave massager . At this time, a plurality of electrode pads 210, 220, 310, and 320 are formed on the bottom surfaces of the both side head parts 200 and 300 contacting the human body, and all of the electrode pads 210, 220, .

The control unit 120 controls the voltage applying unit 130 to generate a corresponding stimulation voltage and the frequency adjusting unit 140 generates medium frequency electricity of different channels. Subsequently, the controller 120 controls the voltage applying unit 130 to output the multi-channel frequency electricity modulated by the frequency adjusting unit 140 through the electrode pads 210, 220, 310, and 320. Since the electrode pads 210, 220, 310, and 320 are in contact with the human body, the mid-frequency electricity output through the electrode pads 210, 220, 310, and 320 stimulates the human body.

The electrode pads 210, 220, 310, and 320 may be formed of metal or conductive plastic.

The controller 120 operates according to the manipulation of the user's input unit 111 to adjust the intensity and frequency of the stimulation of the mid-frequency electric power. In addition, the voltage application unit 130 can operate such as a soft start in which a stimulation voltage is gradually increased in order to prevent generation of a stimulation voltage, generation of a discharge, and sudden strong stimulation.

For reference, since the mid-frequency massager according to the present embodiment must stimulate a wide range of subcutaneous tissue and deep muscles, it is preferable to employ a relatively high frequency band or a mid-frequency band frequency in a general low frequency band. For deeper muscle movements, frequencies in the mid-frequency band of 850-1100 Hz are employed.

The mid-frequency massager according to the present embodiment uses a lithium ion polymer battery of about 3 to 4 V and 1,800 mA as a driving source for operation of the apparatus.

FIG. 3 is a graph for explaining the beat frequency phenomenon of the mid-frequency massager according to the present invention, and FIG. 4 is a view for explaining a configuration of an electrode pad of the mid-frequency massager according to an embodiment of the present invention.

4, four electrode pads are exposed on the first head part 200 and the second head part 300, respectively, which are different from each other. However, as shown in FIG. 4, The first electrode pad 210 and the second electrode pad 220 are formed on the first head part 200 and the third electrode pad 310 is formed on the second head part 300. Therefore, And the fourth electrode pad 320 are formed. Here, one electrode pad has two exposed portions exposed to the outside along the longitudinal direction of the handle 100 as shown in the figure.

Herein, any one of the first electrode pad 210 and the second electrode pad 220 of the first head part 200 and the third electrode pad 310 and the fourth electrode pad of the second head part 300 320 are formed as different positive and negative electrodes, waves of different frequencies are generated in the skin of the user's body, and a beating phenomenon occurs at this interference point. That is, beating occurs in the subcutaneous tissues and deep muscles of the human body. Accordingly, since the first head 200 and the second head 300 are not directly connected to each other and are spaced apart from each other by a predetermined distance, the first head 200 and the second head 300 can be stimulated over a wider range than a conventional single head. In the conventional middle frequency abdominal fat remover, since the bottom surface where the electrode pads are gathered is not wide, only the irritation to the narrow part is possible, so that the irritation should be continued for a predetermined time so that the abdominal fat removal effect can be obtained. A large amount of time and trouble can not be avoided. On the other hand, the mid-frequency massager according to the present invention has a merit that the user can contact the user's skin through two separate heads to stimulate a wider area.

More specifically, as shown in FIG. 3, when the vibration graph y1 of the middle frequency and the vibration graph y2 of the other middle frequency are interfered with each other, Wave ') occurs as shown in the graph (y1 + y2). Here, the beat wave stimulates the subcutaneous tissues and deep muscles of the human body while causing a regular change in frequency, and relaxes and contracts the subcutaneous tissues and deep muscles while regularly changing the intensity of the mid-frequency stimulus. Stimulation can be repeated over a wide range of subcutaneous tissues and the like.

Meanwhile, since the conventional medium frequency abdominal fat remover has four electrode pads disposed on one plate-like bottom face, which is hard, it can be used only in the abdominal region of the human body having a relatively flat outer face, and can be used in a curved region or a thin and narrow region It was difficult to use it in the skin area, calf, and thigh area.

In consideration of this, the mid-frequency massager according to the present invention is configured such that the first head part 200 and the second head part 300 can be rotated. The turning operation of the head unit will be described in detail with reference to FIGS. 5 and 6. FIG.

FIG. 5 is a partly exploded perspective view illustrating a rotation part of a head part of a mid-frequency massager according to an embodiment of the present invention. FIG. 6 is a view for explaining a rotation operation of a head part of a mid- .

The first head unit 200 and the second head unit 300 are pivotally moved about a connecting portion with the handle 100 and the pivoting direction of the first head unit 200 and the second head unit 300 The first head part 200 and the second head part 300 which are in a horizontal direction (see FIG. 6A) (See Fig. 6 (b)) from about 10 DEG to 50 DEG.

As shown in FIG. 5, the hinge portions 161 and 171 are built in the first head portion 200 and the second head portion 300 for the rotation of the head portion.

The hinge portions 161 and 171 are housed in the housings 230 and 330 constituting the first head portion 200 and the second head portion 300 so that the housings 230 and 330 are engaged with the handle 100, It is made to rotate about the connecting part.

The hinge portions 161 and 171 are fixed to the connecting portions 160 and 170 at the lower ends of the handles 100 and the other ends of the hinges 161 and 171 extend to the inside of the housings 230 and 330, The pivot grooves 162 and 172 are formed correspondingly.

At this time, inner walls 231 and 331 fixed in the horizontal direction are provided inside the housings 230 and 330. Mounting holes 231a and 331a are formed in the inner walls 231 and 331, respectively.

The portions of the rotation grooves 162 and 172 of the hinge portions 161 and 171 are received in the installation holes 231a and 331a of the inner walls 231 and 331, The inner walls 231 and 331 and the hinge portions 161 and 171 are engaged with each other. The engaging clips 163 and 173 are fitted into the rotating grooves 162 and 172 of the hinge portions 161 and 171 and are rotated along the rotating grooves 162 and 172. The engaging clips 163 and 173 are formed on the outer side, The inner walls 231 and 331 are engaged with the installation holes 231a and 331a of the inner walls 231 and 331 so that the inner walls 231 and 331 are coupled with the hinges 161 and 171, .

When the external force of the user is applied to the housings 230 and 330, the external force is transmitted to the coupling clips 163 and 173 through the inner walls 231 and 331, The housing 230 and the housing 330 are rotated around the connecting portion with the handle 100 as a result of the rotation of the hinge portions 161 and 171 along the rotation grooves 162 and 172 of the hinge portions 161 and 171.

6, the housings 230 and 330 constituting the first head part 200 and the second head part 300 are in a horizontal state as shown in FIG. 6 (a) The housing 230 or 330 rotates to face the facing portion of the first head 200 and the second head 300 as shown in Figure 6B so that it is closer to the handle 100 The posture is switched in the losing direction.

As the first head 200 and the second head 300 are rotated as described above, not only the outer surface of the human body, which is comparatively flat like the abdominal region of the human body, but also the curved portion of the human body or a thin and narrow region (for example, , Thigh region).

In particular, such a pivoting motion of the head portion can transmit a deeper stimulus to a human body having a region with an excessively large amount of fat and protruding portions. 7 is a view for explaining an operation state of the mid-frequency massager according to an embodiment of the present invention.

FIG. 7 shows a state in which both side head portions 200 and 300 are in contact with each other in a state in which the both side head portions 200 and 300 are pivoted to a part of a human body protruding from a large amount of fat.

The beating waves generated between the two head portions 200 and 300 have a limited depth to be transmitted to the inside of the human body when the two head portions 200 and 300 are in a horizontal state. However, in the present invention, a pair of electrode pads for generating a beat wave are separately formed in the two side head portions 200 and 300, and the side head portions 200 and 300 are rotated to contact the convex human body portion A point at which waves of different frequencies generated by the two head portions 200 and 300 are generated and cause beat waves due to interference will be formed at deeper points (subcutaneous muscles and fats) of the human body, The stimulation is performed together with the heat generation due to the electrical resistance of the human body, so that the muscle exercise effect and the fat decomposition effect can be obtained together.

In the meantime, the conventional medium frequency abdominal fat remover can be driven only when all the electrode pads are brought into contact with the skin of the human body. To this end, users should pay special attention to prevent the electrode pads from falling off the skin during use. The electrode pads must be continuously applied to the device in order to maintain the skin contact of the electrode pads. In addition, since the conductive gel must be applied to the skin every time the device is moved to another site, there is a problem that it is inconvenient to use.

In consideration of the above, the middle frequency massager according to the present invention is configured such that each of the head portions has a skin adsorption function and a conductive gel injection function. The skin adsorption and conductive gel injecting function of the head portion will be described in detail with reference to FIGS. 8 and 9. FIG.

FIG. 8 is a view for explaining a skin absorption configuration of a head of a mid-frequency massager according to an embodiment of the present invention and a skin injection configuration of a conductive gel. FIG. 9 is a cross- The adsorption function and the skin-injecting function of the conductive gel.

Referring to FIG. 8 (a), a skin absorption structure of a head of a mid-frequency massager according to an embodiment of the present invention will be described.

Attachment walls 260 and 360 are provided along the outer edges of the electrode pads on both sides of the head 200 and 300 and flow ports 240 and 340 for sucking air are formed on the bottom of the head 200, (See Fig. 4). One end of each of the flow lines 241 and 341 is connected to the flow ports 240 and 340 and the other end of the flow lines 241 and 341 is connected to a fixed block 181 And is configured to be airtight.

A button 180 is provided at a lower portion of the handle 100 so that one side thereof protrudes to the outside and can easily be held by a finger when the user grips the handle 100. The button 180 is pressed by a user, (100), and when the user depresses the pressing force, it is toggled to maintain the protruding state again. The elastic member 183 having elasticity is interposed between the fixing base 181 and the button 180. The elastic member 183 is inserted between the fixing base 181 and the elastic member 182, Respectively.

Accordingly, when the user holds the handle 100 and presses the button 180, the button 180 is moved to the inside of the handle 100 and the air in the expansion joint pipe 182 flows into the distribution lines 241 and 341, . The discharged air will be discharged through the flow ports 240 and 340 of the head units 200 and 300 along the distribution lines 241 and 341.

When the user releases the force pressing the button 180 of the handle 100 while the user is in contact with the skin of the head 200 and 300, the button 180 is released from the elastic member 183 and is pushed out of the handle 100. In this process, the expansion joint pipe 182 expands and suctions the air through the distribution lines 241, 341. The air rapidly escapes from the space between the adsorption walls 260 and 360 of the head units 200 and 300 and the adsorption walls 260 and 360 are completely brought into close contact with the skin, And 300 can be kept in close contact with the skin, and can maintain the contact state without any external force.

Then, the adsorption can be easily released by the air injection operation by the operation of pressing the button 180.

Here, the adsorption walls 260 and 360 may be formed of a material having a high flexibility, in particular, a transparent rubber, a transparent plastic, or a transparent silicon material.

The elastic member 183 may be a spring.

Therefore, the user does not need to worry about the electrode pads dropping from the skin even when the device is not used, and especially when the device is in contact with the human body in a sitting or line state, the contact of the electrode pads is maintained without external force, .

Referring to FIG. 8 (b), a skin infusion configuration of a conductive gel of a mid-frequency massager according to an embodiment of the present invention will be described.

A plurality of injection ports 250 and 350 for discharging the conductive gel are formed on the bottom surfaces of the head parts 200 and 300 (see FIG. 4). One ends of injection lines 251 and 351 for transferring the conductive gel are connected to the injection ports 250 and 350 and the other ends of the injection lines 251 and 351 are connected to a mounting base 181 inside the handle 100 And is fixed to a fixed dome 187. The lower portion of the fixed dome 187 is coupled with a pressing member 186 which contracts and relaxes according to a pressing force. The inner space formed by the fixed dome 187 and the pressing member 186 is filled with a conductive gel. The pressing member 186 is formed in a dome shape as a whole convex toward a lower portion, that is, a button 180, and is formed of a soft material such as rubber, plastic, or silicone, and its shape is changed according to an external force.

A button 180 is provided at a lower portion of the handle 100 so that one side thereof protrudes to the outside and can easily be held by a finger when the user grips the handle 100. The button 180 is pressed by a user, (100), and when the user depresses the pressing force, it is toggled to maintain the protruding state again.

Accordingly, when the user holds the handle 100, when the user pushes the button 180, the button 180 is moved to the inside of the handle 100 and pushes up the pressing member 186. By this external force, (186) contracts and discharges the conductive gel inside the injection lines (251, 351). The conductive gel thus discharged will be discharged through the injection ports 250 and 350 of the head units 200 and 300 along the injection lines 251 and 351.

Accordingly, the user can apply the conductive gel to the skin only by pressing the button before driving the device, without needing to manually apply the conductive gel to the skin every time the device is moved to another part of the human body when using the device, Improved. In particular, such a conductive gel having a cream-like state was not only notoriously frustrating and unpleasant from the conductive gel when applied to the skin, but also had to wipe the gel on the hands after use. In the middle-frequency massage device according to the present invention, And can be applied to the irritation site by an automatic spraying method when necessary, thereby solving the problem at once.

On the other hand, the skin adsorption function and the conductive gel injection function of the above-described head part can be simultaneously realized by a single button pressing operation. 9 is a view for explaining a skin adsorption function of a head of a mid-frequency massage device and a skin injection function of a conductive gel according to an embodiment of the present invention.

9 (a), a fixing base 181 and a flexible joint pipe 182 are coupled to one side of the inner side of the button 180, and between the fixing base 181 and the button 180, The elastic member 183 is inserted and connected. A pressing member 186 which is contracted and relaxed in accordance with the pressing force is disposed on the other side of the inner surface of the button 180 together with the fixed dome 187. In this case, distribution lines 241 and 341 for transferring air are connected to the fixing table 181, and injection lines 251 and 351 for transferring the conductive gel are connected to the fixed dome 187.

In such a device standby state, the user will determine the stimulation site and place the device on the skin of the stimulation site. Accordingly, the first head portion 200 and the second head portion 300 are in contact with the skin.

9 (b), when the user pushes the button 180 while holding the handle 100 for use of the device, the button 180 is moved to the inside of the handle 100, Thereby pushing up the member 186. By this external force, the pressing member 186 contracts and discharges the conductive gel inside the injection lines 251 and 351. The conductive gel thus discharged will be applied to the skin of the stimulation site. Also by this operation, the expansion joint pipe 182 will be contracted.

9 (c), when the user releases the force of the button 180 of the handle 100, the button 180 is moved to the elastic member 183 of the expansion joint pipe 182 And is pushed out of the handle 100. In this process, the expansion joint pipe 182 expands and sucks air through the distribution lines 241 and 341. [ The air rapidly escapes from the space between the adsorption walls 260 and 360 of the head units 200 and 300 and the adsorption walls 260 and 360 are completely brought into close contact with the skin, And 300 can be kept in close contact with the skin, and can maintain the contact state without any external force. Also by this operation, the urging member 186 will return to a circular shape.

As described above, the skin adsorption function and the conductive gel injection function of the head part can be simultaneously realized by a single button pressing operation. If the button pressing operation is performed once each time the stimulation area is moved, the skin of the conductive gel is applied and the adsorption The fixing and the fixing are sequentially performed together, so that the usability and convenience are greatly increased.
