Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin activating device utilizing the cooling and heating actions of an electronic cooling element.

[0002]

2. Description of the Related Art Conventionally, a skin activating device using an electronic cooling element such as a semiconductor element has been known (Japanese Patent Laid-Open No. 1-25).
It has also been put into practical use with No. 9859).

Such an apparatus uses an electronic cooling element in which a pair of N-type semiconductor and P-type semiconductor are electrically connected in series, and a heat-generating surface and a heat-absorbing surface are sandwiched by metal plates. Etc. The electronic cooling element used in this device is known as a so-called semiconductor Peltier element and is generally commercially available.

When this apparatus is used, the metal plates arranged on both sides of this element are cooled and heated by energizing the electronic cooling element. Therefore, the metal plates are alternately turned on and off in the required cycle. Contact. As a result, the contact surface of the skin is cooled or heated so that blood vessels in the skin are contracted or expanded, and activation of the skin is obtained.

[0005]

However, the electronic cooling element used in the above-described device generally has a constant temperature difference between the cooling surface and the heating surface during operation.
Therefore, if the cooling surface and the heating surface are left in the operating state, the cooling surface gradually changes to the atmospheric temperature while maintaining a constant temperature difference between the cooling surface and the heating surface. When the cooling surface is close to the ambient temperature,
The cooling effect on the skin is not obtained and the activation effect is halved. Further, the temperature of the heating surface rises with a certain temperature difference from the cooling surface as the temperature of the cooling surface approaches the atmospheric temperature, so that the temperature of the heating surface becomes too high and adversely affects the skin.

Further, since such a device is adapted to be used by being connected to a household outlet as a power source,
It could not be used in a room without an outlet, or it had to be extended from a room with an outlet by a table tap or the like to be connected, which was troublesome in use.

Therefore, in view of the above points, an object of the present invention is to provide a skin activating device which can obtain stable cooling and heating operations and can be used cordlessly.

[0008]

As shown in FIG. 1, for example, the skin activating device of the present invention includes an electronic cooling element 6 having an endothermic and exothermic action, and a cooling surface and a heating surface of the electronic cooling element 6. A cooling body 3a and a heating body 3b, each of which is arranged of a metal plate, and an air cooling means 7 provided on the heating body 3b.
Heat dissipation means 8 and 9 for allowing the atmosphere to pass therethrough, a battery 13 for supplying electric power to the entire apparatus, and a case 2 provided with air holes 5 and 10 for allowing the inflow and outflow of the atmosphere. It was done.

[0009]

The heating element arranged on the heating surface of the electronic cooling element is provided with the air cooling means by a plurality of through holes or fins, and the fan of the heat radiating portion arranged inside is rotated through the air cooling means to inject the atmosphere. It is made to flow out and the heat of the heating body is radiated to lower the temperature. With this, as the temperature of the heating element decreases, the cooling temperature of the cooling element on the opposite surface can be maintained below the atmospheric temperature, so that the skin can be activated with a stable cooling effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The skin activating device of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing the external appearance of the skin activation device of the present invention. In FIG. 1, reference numeral 1 denotes a skin activating device, which will be described in detail later, but is provided with a case 2 made of, for example, an insulator such as plastic, a cooling body 3a made of, for example, a metal plate, and a power switch 4 arranged at a tip portion. Has been. The case 2 is provided with an air hole 5 for letting in air into the vicinity of a tip end portion thereof, and an air hole 10 (FIG. 2) for letting out air that has flowed into the back side of a rear portion which is a grip portion. On the back side of the cooling body 3a,
A heating element 3b made of a metal plate similar to the cooling element 3a (FIG. 2)
Are arranged.

FIG. 2 is a sectional view taken along the line AA of the embodiment shown in FIG. 1, showing the internal structure. At the tip of the case 2, an electronic cooling element 6 composed of a generally commercially available semiconductor Peltier element similar to the one described in the above-mentioned conventional example.
Are arranged. Further, the heating element 3b is provided with a plurality of through holes 7 in the longitudinal direction of the case 2 as air cooling means so that the outside atmosphere can flow in through the air holes 5 at the tip of the case 2.

Reference numeral 8 is a motor having a fan 9 attached to its shaft, and the rotation of the fan 9 allows the air to flow in through the air holes 5 and the through holes 7 to radiate the heating element 3b and suppress the temperature rise. It becomes the heat dissipation part. An air hole 10 is provided below the motor 8 of the case 2, which is a fan 9
This is for letting out the atmosphere that has flowed in due to the rotation of. The air hole 10 may be located at any position on the case 2 as long as it is behind the fan 9 of the motor 8. The motor 8 has front and rear bearings protruding from the inner wall of the case 2, for example, 2
It is fitted and held in the groove of one holding plate and fixed.

A control unit 11 is connected to the motor 8 and the switch 4, and is also connected to a temperature sensor 12 arranged at the end of the heating surface of the electronic cooling element 6, and the temperature sensor 12 detects the temperature. The motor 8 is controlled according to the preset temperature of the heating surface. That is, when it is detected that the temperature sensor 12 exceeds this set value, the motor 8 (fan 9) is rotated by this detection signal to allow air to flow in to radiate heat from the heating surface and suppress the temperature rise. .

Reference numeral 13 denotes a battery, which is inserted into the rear end portion of the case 2 and supplies electric power to the control unit 11 and the motor 8 via the switch 4. The battery 13 is held by a battery holder 14 attached to the case 2. For example, if a rechargeable secondary battery is used, the battery does not need to be replaced and is easy to use, but it goes without saying that a normal dry battery can also be used. When a secondary battery is used, it can be set in a charger (not shown) by providing charging terminals Ta and Tb on the rear end surface of the case 2, for example.

FIG. 3 is a sectional view taken along line BB of the embodiment shown in FIG. As is apparent from FIG. 3, the heating element 3b is provided with a plurality of through holes 7, and the outside or inside atmosphere is allowed to flow in or out through the through holes 7 during operation to suppress the temperature rise of the heating element 3b. can do.

In the above-described embodiment, in order to effectively cool the cooling body 3a, the cooling body 3a may be formed to be smaller or thinner than the heating body 3b. With this configuration, when the electric energy applied to the electronic cooling element 6 is constant, the heat capacity of the cooling body 3a becomes small, and the thermal response of the cooling body 3a can be accelerated. Therefore, since the cooling body 3a is cooled quickly, the time required for cooling is shortened and the apparatus can be used immediately.

FIG. 4 is a block diagram showing the electrical construction of the embodiment. The operation of the embodiment will be described with reference to FIG. First, the power switch 4 is turned on to turn on the skin activation device 1. The fan 9 rotates as the motor 8 rotates, and the outside atmosphere flows into the case 2 through the air holes 5 at the tip of the case 2 and the through holes 7 of the heating body 3b. The inflowing air deprives the heat of the heating element 3b and is released to the air again from the air holes 10.

The temperature sensor 12 arranged at the end of the heating surface of the electronic cooling element 6 detects the temperature of the heating surface and outputs a detection signal to the control unit 11. When the temperature of the heating surface becomes equal to or higher than the set temperature, the control unit 11 rotates the motor 8 to cause the air holes 5
And external air is made to flow in through the through hole 7 of the heating element 3b.

Therefore, when the air flows into the atmosphere, heat is taken from the heating element 3b, and the temperature rise of the heating surface of the electronic cooling element 6 is suppressed. As the temperature of the heating surface decreases, the temperature of the cooling surface also falls below the atmospheric temperature. The heating and cooling actions of the heating element 3b and the cooling element 3a can always be stably maintained.

In the above-described embodiment, the atmosphere is introduced from the outside through the air holes 5 and the through holes 7, and the air holes 10
Although it is made to flow out from it, the reverse is also good. That is, the atmosphere can be made to flow in from the air holes 10 and be made to flow out to the outside via the through holes 7 and the air holes 5.

When suppressing the temperature rise of the heating element 3b, the rotation speed of the motor 8 may be controlled in accordance with the temperature rise. That is, since the detection signal of the temperature sensor 12 attached to the heating element 3b increases as the temperature of the heating element 3b rises, the rotation speed of the motor 8 is controlled to increase or decrease accordingly.

Further, a through hole 7 is provided as an air cooling means for the heating element 3b.
However, as another air cooling means, for example, a large number of fins (corrugated bodies) are provided on the inner surface of the heating element 3b excluding the contact surface with the electronic cooling element 6, and the air is introduced by the fan 9 through the fins. Even if it is made to flow out, the temperature rise can be suppressed. Further, by using the through holes 7 and the fins together, the effect of suppressing the temperature rise can be further enhanced.

Further, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various other configurations can be adopted without departing from the gist of the present invention.

[0024]

As described above, according to the present invention, since the temperature of the heating body on the heating surface side of the electronic cooling element is forcibly radiated to suppress the temperature rise, the cooling body on the cooling surface side is suppressed. The temperature can be maintained below the ambient temperature, stable cooling and heating effects can be obtained, and the skin can be effectively activated.

Further, since it can be driven by a battery, there is an advantage that a power cord is not required and it is easy to use regardless of where it is used.
