Description

Eye massager including carbon-based highly conductive silicone composite pad}

The present invention relates to an eye massage provided with a carbon-based highly conductive silicone rubber composite pad.

The eye massager relieves eye fatigue by providing acupressure and heat around the eyeball.

In general, an eyeball massager is composed of an eyepatch made of cloth and sponge, and a heating element built into the eyepatch to transfer heat to the eyeball.

In the eyeball massager having such a structure, heat is lost in the process of being transferred to the eyeball through the eye patch. In addition, in the process of transferring heat to the eyeball via the eyepatch, there is a problem in that the heat is not uniformly transferred to the eyeball depending on the degree of close contact between the eyepatch and the eyeball.

In order to solve this problem, the eye massager disclosed in Korean Registered Patent (10-2227349), the goggle body is bent in response to the shape of the wearer's head to bring the heating space into close contact with the eyeball with the maximum contact area, and the aluminum plate is used as a heating element. The heat of the eye is uniformly and consistently transferred to the front of the eyeball.

However, this eye massager also has problems in that the heat of the heating element is indirectly transferred to the eyeball through the aluminum plate, resulting in loss, and the structure becomes complicated and the weight increases due to the aluminum plate.

Hereinafter, an eye massage provided with a carbon-based highly conductive silicone rubber composite pad according to an embodiment of the present invention will be described in detail.

As shown in Figures 1 to 3,

The eye massager 1 is composed of a front part 10, a cushion part 20, a band 30, a power supply part 40, and a silicone rubber composite pad 50. In addition, the eyeball massager 1 includes various functions such as a vibration massage function and a music listening function. In this embodiment, only the function related to heat generation of the silicone rubber composite pad, which is the gist of the present invention, will be described in detail.

front part (10)

The front part 10 may be made of various materials such as plastic, rubber, cloth, and metal. A power switch 11, a remaining battery indicator 12, a temperature control button 13, and a time control button 14 are installed on the front part 10. Of course, various types of buttons having various functions may be installed.

Cushion part (20)

The cushion part 20 is made of sponge or rubber. The cushion part 20 is attached to the rear side of the front part 10 . When worn, the cushion part 20 adheres closely to the periphery of the eyeball. A mounting groove 21 in which the silicone rubber composite pad 50 is installed is formed in the cushion part 20 . Mounting grooves 21 are respectively formed on the left and right sides of the rear surface of the cushion part 20, which are positioned at the user's eyeball position when the user wears the massage device 1. When the eyeball massager 1 is worn, the thickness of the silicone rubber composite pad 50 is preferably 1 to 3 mm thicker than the depth of the mounting groove 21 so that the user's eyeballs come into close contact with the silicon rubber composite pad 50.

band(30)

The band 30 is made of an elastic material such as rubber.

The band 30 is connected to the left and right ends of the front part 10 and is covered on the back of the head to fix the eye massager 1 to the head.

power unit (40)

The power supply unit 40 is composed of a + electrode 41, a - electrode 42, and a battery (not shown). The power supply unit 40 supplies power to the silicon rubber composite pad 50 .

The +electrode 41 and the -electrode 42 are installed on the bottom of the mounting groove 21 and are spaced apart at regular intervals up and down. Of course, they may be spaced apart from each other left and right, and their positions may vary.

When the silicone rubber composite pad 50 is inserted into the mounting groove 21, the + electrode 41 and the - electrode 42 come into close contact with the silicone rubber composite pad 50. When the battery sends current to the + electrode 41 and the - electrode 42, the current flows through the nano-carbon tubes of the silicon rubber composite pad 50, and heat is generated by the resistance of the nano-carbon tubes.

Silicone rubber composite pad (50)

As shown in FIG. 1(b), the silicone rubber composite pad 50 has a three-dimensional shape so as to be in close contact with the eyeball.

The silicone rubber composite pad 50 is made of a carbon-based highly conductive silicone composite material. The silicone rubber composite pad 50 is in close contact with the eyeball. Due to this, heat is transferred to the eye evenly without heat loss.

As shown in FIG. 2, the silicone rubber composite pad 50 is composed of a polydimethylsiloxane matrix and carbon nanotubes uniformly dispersed in the polydimethylsiloxane matrix.

Polydimethylsiloxane (PDMS) is a polymer that is harmless to the human body and has excellent air permeability and flexibility similar to that of living tissue.

By using polydimethylsiloxane having such properties as a base of the silicone rubber composite pad 50, even if the silicone rubber composite pad 50 directly contacts the eyeball, it is harmless.

The heating value of the silicone rubber composite pad 50 is controlled according to the content of the carbon nanotubes dispersed in the polydimethylsiloxane matrix.

FIG. 2 is a view showing a silicon rubber composite pad in which carbon nanotubes are uniformly dispersed. In the order of FIGS. The content of carbon nanotubes increases.

For example, the silicon rubber composite pad 50 shown in FIG. 2 (a) contains 2 wt% of carbon nanotubes, and the silicon rubber composite pad 50 shown in FIG. 2 (b) contains carbon nanotubes. 4 wt%, and the silicon rubber composite pad 50 shown in FIG. 2(c) includes 8 wt% of carbon nanotubes. Of course, the content of carbon nanotubes may vary.

However, when the content of the carbon nanotubes exceeds 8 wt%, it is difficult to manufacture the silicone rubber composite pad 50, and the hardening may cause eye pain. On the other hand, when the amount of carbon nanotubes is less than 2 wt %, the resistance is high, making it unsuitable for generating heat. Therefore, the content of carbon nanotubes is preferably 2 to 8 wt%.

On the other hand, as the content of the carbon nanotubes increases, the resistance of the silicon rubber composite pad 50 decreases, so that the amount of heat generated at the same current gradually decreases.

Using this principle, it is possible to make a set of silicon rubber composite pads 50 having different calorific values by adjusting the content of the carbon nanotubes.

Hereinafter, the silicon rubber composite pad 50 having a content of 2 wt% of carbon nanotubes shown in FIG. 2 (a) is referred to as a high-heat silicone rubber composite pad 50a, and The silicone rubber composite pad 50 having a content of 4 wt% is referred to as a medium heating silicone rubber composite pad 50b, and the silicon rubber composite pad having a carbon nanotube content of 8 wt% shown in FIG. 2 (c) ( 50) is referred to as a low-heat silicone rubber composite pad 50c.

Silicon rubber composite pad (50) manufacturing method

The silicone rubber composite pad 50 is manufactured through the following steps (A), (B), (C) and (D).

(A) step

This is a step of ultrasonic treatment by mixing carbon nanotubes and isopropyl alcohol.

In step (A), the reason why isopropyl alcohol is used as a solvent is that the solvent mixed with the carbon nanotubes must be evaporated without leaving air for excellent conductivity when the solvent is evaporated later. The most suitable solvent for this is isopropyl alcohol.

(B) step

This is a step of ultrasonic treatment by adding dimethyl silicone oil to a mixture of carbon nanotubes and isopropyl alcohol.

In step (B), the reason why dimethyl silicone oil is used is that when polydimethylsiloxane is directly added to a mixture of carbon nanotubes and isopropyl alcohol, the dispersibility of the carbon nanotubes is lowered.

(C) step

This step is to add and mix polydimethylsiloxane to the mixture to which dimethyl silicone oil is added.

(D) step

It is a step of putting the mixture mixed in step (C) into a molding mold having a silicone rubber composite pad shape and curing it at a set temperature and time to mold it into a silicone rubber composite pad shape. Here, the set temperature is 60 to 90 ° C, and the set time is 1 to 3 hours.

The reason for ultrasonic treatment in the steps (A), (B), and (C) is that the carbon nanotubes try to unite by the van der Waals force, (A), (B), ( C) This is because carbon nanotubes cannot be uniformly dispersed in a polydimethylsiloxane (PDMS) matrix at any stage without sonication.

Ultrasonic treatment is performed for 10 to 40 minutes at a frequency of 40 to 5,000 kHz and an intensity (spatial peak pulse average intensity: ISPPA) of 50 to 1,000 mW. Due to this frequency range, intensity, and time, damage to the carbon nanotubes is minimized, and the carbon nanotubes can be uniformly dispersed in the polydimethylsilonic acid matrix.

Detachable silicone rubber composite pad (50)

The silicone rubber composite pad 50 may be fixed to the mounting groove 21 or, as shown in FIG. 3 , may be detachable or attached to the mounting groove 21 .

To this end, if the silicone rubber composite pad 50 does not easily fall out of the mounting groove 21, the overall size of the silicone rubber composite pad 50 is larger than that of the mounting groove 21 by about 0.1 to 0.2 mm so that it can be easily pulled out with an appropriate force. it is desirable

If the silicone rubber composite pad 50 can be attached to and detached from the mounting groove 21 in this way, as shown in FIG. 4 (a), the high-heating silicone rubber composite pad 50a shown in FIG. It can be inserted into the positioned mounting groove 21. Alternatively, the medium heating silicone rubber composite pads 50b shown in FIG. 2(b) may be inserted into the mounting grooves 21 located on the left and right sides. Alternatively, the low-heating silicone rubber composite pads 50c shown in FIG. 2(c) may be inserted into the mounting grooves 21 located on the left and right sides.

On the other hand, a set of silicone rubber composite pads 50 having different calorific values are prepared in advance, and the silicon rubber composite pad 50 having a calorific value suitable for treating dry eye syndrome, or a silicon rubber having a user-customized calorific value that is comfortable according to the user The composite pad 50 can be easily replaced and used if necessary.

In addition, if the silicone rubber composite pad 50 with different calorific value can be attached or detached from the mounting groove 21, the silicon rubber composite pad 50 is primarily replaced to adjust the calorific value in a wide range, and then the temperature control button With (13), the calorific value can be controlled in a second narrow range. Therefore, it is possible to precisely and easily control the temperature suitable for treating dry eye syndrome or the calorific value that the user feels comfortable with.

In addition, as shown in FIG. 4(d), according to the condition of the left and right eyes, the low-heat silicone rubber composite pad 50 is mounted in the left mounting groove 21, and the medium-heating silicone rubber is mounted in the right mounting groove 21. A composite pad 50 may be mounted. Of course, the combination of the silicone rubber composite pads 50 having different calorific values attached to the left and right mounting grooves 21 may be varied.
