Description

Skin massager for cold and hot use {Skin massager for heating and cooling}

The present invention relates to a skin beauty machine, and more particularly, to a heat-and-collective skin beauty machine that does not generate noise while increasing the temperature of a cold massage by bringing a heat storage unit filled with water into an aluminum block.

Thermoelectric element is an element that uses endotherm or heat generation by Peltier effect. When different electrodes are connected on both sides and power is supplied to it, heat is generated from the front side and cold air is generated from the rear side. When supplied, cold air is generated at the front and heat is generated at the rear.

In the conventional cold and hot skin care device using the thermoelectric element, the heat sink is in close contact with the rear surface of the thermoelectric element to dissipate heat generated from the thermoelectric element to cool the thermoelectric element.

For example, by supplying power to the thermoelectric element to generate cold air to the front of the thermoelectric element to perform a cold massage, because the heat is generated from the rear of the thermoelectric element should be cooled. This is because the temperature of the heat generated from the rear surface of the thermoelectric element continuously rises and the heat affects the front surface of the thermoelectric element. That is, since the heat generated from the rear of the thermoelectric element increases the temperature of the cold air generated from the front of the thermoelectric element, the cold massage effect is reduced.

For this reason, since it is very important to cool the heat generated in the thermoelectric element, it is essential that a heat sink for cooling the heat generated in the rear of the thermoelectric element be installed in the rear of the thermoelectric element.

At this time, if the thermal conductivity of the heat sink is lowered or the heat sink is overheated, the heat generated from the rear surface of the thermoelectric element may not be properly cooled, and the heat may affect cold air generated from the front surface of the thermoelectric element, thereby reducing the cold massage efficiency.

Accordingly, a problem arises in that the duration of the cold massage is shortened only by the heat sink.

In order to solve this problem, a cooling fan is attached to the rear of the heat sink, and a heat discharge hole is formed in the massager, and the heat generated from the heat sink is driven by the cooling fan to be forced out of the main body through the discharge hole. That is, conventionally, in order to increase the duration of the cold massage, a cooling fan for cooling the heat sink was essential.

However, a loud noise is generated due to the operation of the cooling fan, and the heat generated through the discharge hole hits the user's skin, causing discomfort. Also, since the cooling fan needs to be attached, the volume becomes large to carry. An uncomfortable problem occurs.

The present invention has been made to solve the above problems, the heat storage portion filled with water in the excellent elastic pocket close to the aluminum block can increase the duration of the cold massage and improve the efficiency of cold massage without generating noise The purpose of the present invention is to provide a combination of cold and hot skin beauty machine.

An object of the present invention, the main body constituting the appearance; and the head portion is provided on a portion of the main body in contact with the skin; and the thermoelectric element installed inside the main body to heat or cool the head portion; and generated in the thermoelectric element In order to move the heat quickly, one surface of the thermal conductive block of the metal material in close contact with the thermoelectric element; And a bag that is in close contact with the other side of the heat conductive block, and is formed of a flexible material that can be contracted and expanded so as to easily adhere while increasing the adhesion area, and filled inside the bag to receive heat from the heat conductive block and accumulate heat or cold air. Is achieved by a cold and hot skin combiner comprising a; heat storage unit having a heat storage solution.

In addition, the thermally conductive block may have an insertion groove into which a portion of the heat storage portion is inserted in one surface in order to increase the contact area with the heat storage portion.

The bag may also be made of PVC or silicone that can be used at low and high temperatures.

In addition, the bag may have a rib formed around the bag to prevent the bag from flowing inside the main body.

In addition, a temperature sensor for measuring the temperature of the head portion; And a control unit which receives the temperature information measured from the temperature sensor and cuts off or applies the power supplied to the thermoelectric element so that the temperature of the head portion maintains the preset massage temperature range.

According to the present invention, the aluminum block having a high thermal conductivity can quickly move heat generated in the thermoelectric element, so that the temperature of the head portion can be lowered or raised quickly. In addition, by adhering the heat storage unit to the rear surface of the aluminum block, there is an effect that can quickly cool the aluminum block received heat from the thermoelectric element, in particular, by accumulating cold air or heat in the heat storage unit without using a cooling fan, cold massage There is an advantage that it can increase the time and does not generate additional noise.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 5, the combined cold and cold skin care machine according to an embodiment of the present invention, the main body 1, the head portion 2, the thermoelectric element 3, the aluminum block 5, the heat storage unit ( 4), a control unit 7 and a battery 8.

The main body 1 is formed in a synthetic resin material such as plastic in a rounded state as a whole, forms a basic appearance, and has a power button 11 and a conversion button 12 for cooling or heating on the front surface thereof. The cover 13 is provided to mount the battery 8 on the rear side.

As for the head part 2, stainless steel is used as the part which contacts skin, and it is provided in convex shape in the front surface of the main body 1 in substantially the shape of a bowl.

The thermoelectric element 3 is installed in close contact with the rear surface of the head 2, and receives the power of the battery 8 to heat or cool the head 2. Here, the thermoelectric element 3 is already widely used and known, and detailed description thereof will be omitted.

The aluminum block 5 is a material having a very high thermal conductivity, and has a substantially cylindrical or rectangular parallelepiped shape and is installed in close contact with the thermoelectric element 3 so as to quickly move hot or cold air generated by the thermoelectric element 3. . In this case, as shown in FIG. 6, an insertion groove 51 may be formed on the rear surface of the aluminum block 5 ′ to widen the contact area with the pocket 41 of the heat storage unit 4. . Accordingly, the aluminum block 5 can quickly heat or cool the head 2 by moving hot or cold air generated in the thermoelectric element 3 quickly.

Meanwhile, a thermal grease G or a thermal conductive pad may be installed between the head portion 2 and the thermoelectric element 3 and between the thermoelectric element 3 and the aluminum block 5. This improves the adhesion between the head portion 2 and the thermoelectric element 3 and the adhesion between the thermoelectric element 3 and the aluminum block 5, and in the thermoelectric element 3 on the head portion 2 and the aluminum block 5. This is to increase the conductivity of generated hot or cold air.

The heat storage unit 4 is formed of a material such as PVC or silicone or heat-resistant rubber, which is excellent in elasticity and withstands high heat and low temperature, but has a thin cross-section thickness to facilitate heat transfer, and has excellent stability and specific heat. This high water is filled inside the pouch 41. Then, the heat or cold air generated in the aluminum block (5) is in close contact with the rear surface of the aluminum accumulates well. Accordingly, the heat storage unit 4 absorbs a large amount of heat from the heated aluminum block 5 to continuously cool the aluminum block 5.

For example, when the aluminum block 5 is heated and heated as a result of receiving heat from the thermoelectric element 3, the heat storage unit 4 cools the aluminum block 5. At this time, the heat storage unit 4 is formed because the specific heat of water is high. By absorbing a large amount of heat from the aluminum block (5) it is possible to cool the aluminum block (5) for a long time.

Here, the bag 41 may be formed with a rib 42 around the bag 41 to prevent the flow in the interior of the body 1, may be screwed to the rib 42 and the body (1) have. For example, when the bag 41 is installed in a state filled with the inside of the main body 1, there is no space left between the main body 1 and the aluminum block 5 so that the bag 41 cannot expand, and the bag 41 ) Requires a larger clearance than the pocket (41). However, if the free space is larger than the bag 41, the bag 41 may flow in the free space. As the bag 41 flows, the bag 41 and the aluminum block 5 and the bag 41 and the main body 1 Friction occurs between the pouches, which causes the pouch 41 to be worn and broken, or the pouch 41 is not properly adhered to the aluminium block 5 so that the aluminum block 5 cannot be cooled properly. Therefore, the ribs 42 are formed around the pocket 41. Accordingly, ribs 42 may be formed around the bag 41 to fix the bag 41 to the main body 1, thereby allowing the bag 41 to flow inside the main body 1 even when the bag 41 expands or contracts. It can be prevented and prevented from being worn, and the aluminum block 5 can be quickly cooled because the pocket 41 can be kept in close contact with the aluminum block 5 at all times. Since the space is formed, the bag 41 can be easily inflated. Accordingly, the water filled in the bag 41 absorbs and accumulates the hot or cold air generated in the aluminum block 5, thereby minimizing the transmission of the hot or cold air generated in the aluminum block 5 to the head portion 2. It is possible to extend the time of the cold and hot massage by continuing the cold or hot air generated in the head (2).

On the other hand, the inside of the bag 41 of the heat storage unit 4 is filled with water so that no space or bubbles are generated, the bag 41 is pressed slightly mounted between the aluminum block 5 and the main body (1). If cooling is performed while the heat storage unit 4 is not pressed, a gap may occur between the aluminum block 5 and the heat storage unit 4 while the bag 41 is contracted. That is, since a gap is generated between the aluminum block 5 and the heat accumulating portion 4 and the adhesion area is reduced, the cooling capacity of the aluminum block 5 is reduced, and since the gap blocks heat transfer, the heat transfer performance is reduced. Therefore, even when the bag 41 shrinks, if the bag 41 is initially mounted in a depressed state, no space is formed inside the bag 41, and a gap does not occur between the aluminum block 5 and the heat storage part 4. Do not.

1 and 2, when the pocket 41 of the heat storage unit 4 is made of a metal case 4 ′ and filled with water in the metal case 4 ′, the metal case is filled with water. When the 4 'absorbs heat, the water and the metal case 4' expand together because there is no space for the water to expand. That is, the water is evaporated inside the metal case 4 'and the metal case 4' expands, and after the deformation is made in the expanded state, even if the metal case 4 'is cooled, the metal case 4' is not restored to its original state. Accordingly, one surface of the metal case 4 'closely attached to the aluminum block 5 is convexly expanded, so that the contact area between the aluminum block 5 and the metal case 4' is reduced, thereby reducing the metal case 4 '. The ability to cool the aluminum block 5 is markedly inferior. In order to solve this problem, if a free space in which water can expand is provided inside the metal case 4 ', heat transfer is not performed in the free space portion. In particular, when massaging the jaw, the water always moves downward by gravity, so the free space is always located at the top of the water. That is, the water must absorb the heat generated from the aluminum block (5), the free space to block the heat transfer can not properly absorb the heat generated from the aluminum block (5) is significantly reduced cooling capacity.

However, in the present invention, since the bag 41 is made of excellent stretchable PVC or silicon, the bag 41 is made of aluminum block 5 regardless of the expansion and contraction of the bag 41 while removing the free space inside the bag 41. ) And always in close contact with each other, by quickly absorbing the heat generated from the aluminum block (5) it is possible to quickly and continuously cool the aluminum block (5).

The control unit 7 changes the polarity of the thermoelectric element 3 while the power is applied by pressing the power button 11 of the main body 1, or the temperature sensor installed in the head part 2 or the aluminum block 5. The head portion 2 is prevented from being overheated as compared with the temperature information received from (S). That is, when the user presses the conversion button 12 of the main body 1, the control part 7 heats or heats the head part 2 by the thermoelectric element 3 so that an on-massage can be performed. Iii) change the polarity of the thermoelectric element 3 so as to massage, and cut off the power supplied to the thermoelectric element 3 when the head 2 is out of the set temperature. At this time, the temperature of the temperature massage is suitable for the range of about 38 ℃ to 40 ℃, the temperature of the cold massage is suitable for the range of 5 ℃ to 7 ℃, if outside the set temperature range, the control unit 7 is a thermoelectric element When the power supplied to (3) is cut off and it is within the set temperature range, the control unit 7 supplies power to the thermoelectric element 3 again. Accordingly, the head unit 2 can maintain the set temperature by turning on / off the power supplied to the thermoelectric element 3 from the control unit 7.

The battery 8 supplies power to the above-described thermoelectric element 3, the control unit 7 and the temperature sensor S, and opens the cover 13 on the rear of the main body 1 to mount the battery 8. .

Here, the cold massage, on-massage and the operation state, so that the eye can easily check the eyes are arranged around the head portion 2 is divided into two colors (hereinafter referred to as "LED (6)"), that is, blue An LED 6 emitting light and red light may be installed in the main body 1. For example, when the power button 11 of the main body 1 is pressed, the blue light and the red light flash alternately to confirm the standby mode state, and when the conversion button 12 is pressed, the blue light or the red light emits light. At this time, when the red light is emitted by pressing the conversion button 12, the head 2 is notified that the massage has been heated, and if the blue light is emitted by pressing the conversion button again, the head 2 is cooled and cooled In this case, pressing the conversion button 12 again switches to the standby mode. Accordingly, the user can know the on massage, cold massage or the standby mode while watching the light emitted from the LED 6.

In addition, the ultrasonic vibration unit for generating ultrasonic vibration in the main body 1 may be further provided. Accordingly, by vibrating the skin during the skin massage can further improve the beauty effect.

Hereinafter will be described in detail the operating state of the skin care device combined with cold and hot according to an embodiment of the present invention.

When the power button 11 is pressed while the battery 8 is mounted on the main body 1, the red light and the blue light alternately emit light from the LED 6.

At this time, when the conversion button 12 is pressed, the red light comes on, the temperature of the front surface of the thermoelectric element 3 rises and the temperature of the rear side decreases, and the thermoelectric element 3 heats the head portion 2 while simultaneously heating aluminum. Cool the block 5. Accordingly, the head portion 2 can be heated by the thermoelectric element 3 and the temperature rises, so that the massage can be performed. The aluminum block 5 is cooled by the thermoelectric element 3, and the heat storage portion 4 is heated. Receives and stores the cold air of the cooled aluminum block (5). On the other hand, when the temperature of the head portion 2 exceeds 40 ° C, that is, 41 ° C, the control unit 7 cuts off the power supplied to the thermoelectric element 3. 7) applies power to the thermoelectric element (3). Therefore, it is possible to maintain a constant temperature within the set temperature range of the on-massage.

Here, when the conversion button 12 is pressed again, the blue light is turned on and the control unit 7 changes the polarity of the thermoelectric element 3 so that the temperature decreases in the front of the thermoelectric element 3 and the reverse side increases in temperature. The thermoelectric element 3 cools the head 2 and simultaneously heats the aluminum block 5. Accordingly, the head portion 2 may be cooled by the thermoelectric element 3 and the temperature may drop, thereby performing a cold massage, and the aluminum block 5 is heated by the thermoelectric element 3 and the heat storage portion 4. While receiving and accumulating the heat of the heated aluminum block (5) while cooling the aluminum block (5). On the other hand, when the temperature of the head portion 2 is less than 5 ° C, that is, 4 ° C, the control unit 7 cuts off the power supplied to the thermoelectric element 3. ) Applies power to the thermoelectric element (3). Therefore, it is possible to maintain a constant temperature within the set temperature range of the cold massage.

Meanwhile, the bag 41 contracts and expands according to the heating or cooling of the aluminum block 5, but the ribs 42 are formed around the bag 41 so that the main body 1 may be expanded or contracted even if the bag 41 expands and contracts. It is possible to maintain the close contact between the aluminum block 5 and the bag 41 without flowing in the interior. For example, it is very easy to install the heat storage portion 4 inside the main body 1, that is, it is very easy to make a close contact, and does not require a complicated configuration or a complicated assembly process to maintain the close contact. In addition, since the pocket 41 is mounted in a pressed state, it always tries to expand, and the expansion force serves to press the aluminum block 5 to closely contact the rear surface of the thermoelectric element 3, thereby improving heat transfer effect.

Next, when the conversion button 12 is pressed again, it switches to the standby mode.

In the conventional massager, only the heat sink is used to cool the thermoelectric element, which has a disadvantage in that the time of the cold massage cannot be extended if the heat sink is rapidly overheated. In order to solve this problem, a separate cooling fan is installed at the rear of the heat sink and heat exhaust holes are formed in the main body to discharge heat generated from the heat sink to the outside. As hot heat is emitted, there is a problem of discomfort to the user.

However, in the present invention, by installing the heat storage unit 4 in close contact with the aluminum block 5, no noise is generated because a separate cooling fan is not needed, and the time of massage or cold massage using high specific heat water is provided. In particular, even if the heat accumulating portion 4 expands or contracts, the adhesion and the adhesion area which are in close contact with the aluminum block 5 can be maintained, and thus the cooling and heat storage capability of the aluminum block 5 is very excellent. The present invention has a structure in which the pouch 41 formed of excellent elasticity PVC or silicone or a heat-resistant rubber material and the heat storage part 4 filled with water without a space inside the pouch 41 are pressed against the aluminum block 5. It is possible because of this. In addition, since the present invention does not require a space for installing a separate cooling fan, it can be slim and compact, and thus is easy to carry, and power consumption can be reduced since power is not supplied to the cooling fan.
