BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin treatment apparatus using intensive pulsed light (IPL) that is periodically irradiated. More particularly, the present invention relates to a portable portable epilator that is easy to carry and has improved cooling function.

It is known that there are about 5 million hairs on the human skin surface, which plays an important role in the human body. However, with the development of society, a body with a small body gained favor and not only women but also men became interested in hair removal.

In recent years, as a hair remover, the laser method and the Intensive Pulse Light (IPL) method are mainly attracting attention. The laser method can use only light of a specific wavelength emitted from a specific medium, whereas the light pulse method emits light having a certain range of wavelength bands in the form of periodic pulses and is used for skin treatment or hair removal. Optical pulse hair removal is a method of irradiating the skin periodically with light having a wavelength in the range of 515 ~ 1200 nm. When these periodic light pulses are irradiated to the skin, the light energy passes through the surface of the skin and concentrates on the hair roots. Generates. This heat destroys only the hair follicles without damaging the surrounding skin, resulting in permanent hair removal. At present, the wavelength band that can be removed with good efficiency is estimated to be 700 ~ 1000 nm. In this light pulse type hair removal machine, important variables in hair removal treatment are skin color, light energy, wavelength range, pulse width, irradiation time, and pulse delay time. To maximize.

1 to 3 is a view showing an example of a skin treatment device using a conventional light pulse. 1 is a type of light skin treatment device described in the prior art in registered utility model No. 20-0360150 "light skin treatment device". When the configuration thereof is briefly described, a main body 1 in which a driving circuit and a power supply and the like are built in, a monitor 2 provided in the main body 1, and a light source for oscillating optical pulses in a range of wavelengths connected to the main body and inside thereof It consists of a handpiece 10 and a cradle 12 is provided with a lamp. However, these types of treatment devices are bulky and expensive, and are mainly used only in professional medical institutions, etc., and there is a problem in that the handpiece itself needs to be replaced when treatment pulses of different wavelengths are required. It is also true that there is a problem that accessibility is very poor for general users because general users cannot easily carry and use.

FIG. 2 is a conventional IPL irradiation apparatus, which is cited as a prior art in Korean Patent Application No. 110-2004-0108860, which is filed with the Korean Intellectual Property Office and published in Korean Patent Application No. 110-2004-0108860, and FIG. 3 is an improved IPL irradiation apparatus. It is a schematic sectional drawing of having a coolant circulation pipe of a circular cross section. In the IPL irradiation apparatus 10, the flash lamp 13 is disposed horizontally inside the main body 11, and the light tube assembly 12 is formed in a direction perpendicular to the flash lamp 13. A cooling water flow path 14 is formed at an outer circumferential portion of the flash lamp 13, and a cooling water circulation pipe 15 is formed outside thereof. In FIG. 3, the reflective mirror 16 of FIG. 2 is removed, and the reflective layer 17 is formed on the inner surface side or the outer surface side of the cooling water circulation pipe 15. However, the above-mentioned problems still remain because the IPL irradiator is also connected to a main body having a separate drive unit for driving the bulky and heavy material, which is mainly made of metal, etc., due to the characteristics of its components. I'm sitting. In addition, since the light irradiated from the flash lamp 13 is reflected to the reflective layer 17 installed across the cooling water and output to the front, there is a problem that the energy density may be lowered and the light efficiency may be lowered. It can also be pointed out that the replacement of the flash lamp 13 is not easy when the life of the flash lamp 13 expires or the output falls.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and it is intended to more efficiently configure the configuration of the device than the conventional and maximize the light efficiency, and has been improved to a structure that is easy to carry and use even ordinary users.

As a means for achieving the above object, the shape of the reflector is greatly improved to improve energy density and light receiving efficiency, and at the same time, to provide an efficient cooling means for heat generation of the flash lamp.

In addition, it is another object of the flash lamp and the filter to be detachably configured to facilitate the replacement of the flash energy when changing the light energy output or when the flash lamp is at the end of its life.

In order to achieve the above object, in the present invention, a hair removal device for removing the hair root of the human body by irradiating the skin with light pulses, a hollow portion is formed along the longitudinal axis, and includes a cooling water between the inner peripheral surface and the outer peripheral surface formed with the hollow portion A main body having an empty space to be formed therein, a flash lamp installed in the hollow part of the main body to irradiate light pulses, and provided at the rear end of the main body to be connected to the flash lamp to receive power from an external power source A driving unit for operating the flash lamp by using the driven circuit, a reflector having a reflective layer formed on an inner surface of the flash lamp spaced apart from the flash lamp, and a wavelength of the light pulse irradiated as being provided at the front end of the main body Comprising filters for adjustment It provides a portable hair removing apparatus using an optical pulse to be characterized.

Here, the reflector is preferably a cylindrical shape having any one side surface selected from both side surfaces except the outer circumference and a hollow portion formed therein. In this case, the reflective layer on the inner surface of the reflector is preferably formed of any one metal selected from nickel, chromium, silver and gold or alloys thereof.

In the above configuration, the driving unit is configured of a circuit including a capacitor, a trigger, and a power supply unit, and has a structure capable of charging a current by an AC input by an external power source.

Meanwhile, a condenser lens may be installed between the flash lamp and the filter to more efficiently collect light emitted from the flash lamp.

The flash lamp and the driving unit are conveniently configured to be detachable by a connector and a socket.

Preferably, the main body is provided with a cooling water inlet and outlet for allowing the cooling water to flow in and out of the main body by being connected to a space part including the cooling water.

Hereinafter, with reference to the accompanying drawings will be described in more detail the configuration and operation principle of the present invention.

4 is a schematic perspective view of a portable epilator using light pulses according to the present invention, FIG. 5 is a schematic longitudinal cross-sectional view of FIG. 4, and FIG. 6 is a cross-sectional view along the cutting line VI-VI of FIG. 5. As shown, the portable epilator 100 of the present invention has a large length and a tubular body 110 having a hollow portion formed therein, a driving unit 140 provided at the rear of the body, and a detachable connection to the driving unit. It is configured to include a flash lamp 122, a reflector 120 between the flash lamp 122 and the main body and a filter 135 provided in the front of the main body 110. The main body 110 is formed of a tubular body having a hollow portion formed therein so that the flash lamp 122 and the like can be installed therein, and a space for the cooling water so that the coolant flows between the inner and outer circumferential surfaces of the hollow portion ( 150) is formed. The cooling water space 150 is preferably formed to extend from the rear end of the flash lap 122 to the front end of the main body 110, in some cases extending to the portion where the drive unit is located. It may be. Typically, the flash lamp 122 for irradiating light pulses is used to charge Xenon gas and the like inside the lamp made of quartz, etc. This flash lamp 122 generates a lot of heat during use. Therefore, the cooling means described above is provided in the main body 110 to cool the heat generated by the flash lamp 122. On the outer circumferential surface of the main body 110, a cooling water inlet 152 connected to the cooling water space 150 of the main body 110 may be provided. This is for the flow in and out of the coolant and the replacement of the coolant. Reference numeral 152a is a plug of the cooling water inlet.

The flash lamp 122 is configured to be coupled to the socket 140a formed in the driving unit 140 by forming a connector 122a at the end of the side connected to the driving unit 140, the flash lamp 122 as necessary ) To be easily replaced. That is, when the flash lamp 122 is to be replaced with the required energy output or when the flash lamp 122 is at the end of its life, the flash lamp 122 can be replaced by simply disconnecting it from the driving unit 140. It was made.

A reflector 120 covering an outer circumferential surface of the flash lamp 122 is disposed at a distance away from the flash lamp 122. The reflector 120 collects the light emitted from the flash lamp 122 and irradiates it to the front side of the main body 110. The reflector 120 is coated with a metal such as nickel, chromium, gold, and silver, which has excellent reflection efficiency. The reflective layer is formed by plating or the like. The length of the reflector 120 may vary depending on the type or length of the flash lamp 122 and the need. In the present invention, the shape of the reflector 122 is configured as a hollow cylindrical shape with an open front end.

In the present invention, the cooling water space portion 150 is formed in the space between the inner circumferential surface and the outer surface of the hollow portion inside the main body 110, the cooling water is filled therein, the reflector 120 is the inner circumferential surface of the main body 110 It is preferred to position it in contact with. In particular, when the main body 110 and the reflector 120 are both cylindrical, the contact area between the reflector 120 and the coolant is widened, and thus the cooling efficiency is excellent. In addition, by adjusting the length of the reflector properly, this cooling effect can be further doubled.

A filter 135 is disposed at the front end of the main body 110 to adjust the wavelength of the light output to a desired wavelength. The filter 135 is configured to be replaceable according to light pulses in a desired wavelength band. For example, the filter 135 may be configured to be easily replaced by configuring a groove into which the filter 135 may be inserted into the lid 112 of the main body 110. Such a filter 135 is sufficient regardless of its material or shape and can pass light of a certain wavelength band. A separate condenser lens 130 may be installed between the filter 135 and the flash lamp 122 to collect and output light more efficiently.

7 is a schematic configuration diagram of a driving unit of the portable epilator of the present invention, and FIG. 8 is a circuit configuration diagram showing an example of a circuit configuration of the driving unit of the present invention.

As shown, the driving unit 140 is installed on the rear side of the main body 110, the driving unit 140 may include a capacitor 142, a trigger 146 and a power source 148. Reference numeral 114 is a power connector for connecting to an external AC power source.

Since the portable epilator 100 of the present invention has a main object of allowing a general user to carry it directly and use it regardless of time and place, it is preferable to make the configuration of the driving unit 140 chargeable. As shown in FIG. 8, an exemplary circuit of the driving unit 140 may be configured around a single-phase full bridge inverter 172, and the inverter 122 may be zero voltage switching. ) The circuit has two operation modes such as a bypass mode and a back-up mode even when the commercial power supply is disconnected. That is, in the bypass mode, the thyristor 173 is in the ON state, and power is almost directly transferred from the AC power supply 175 to the flash lamp 122 serving as the load, and the uninterruptible power supply current waveform improvement and the battery 174 are performed. It will be charged. In this bypass mode, the output voltage is determined by the supply voltage. In the backup mode, the thyristor 123 is in an OFF state, and the uninterruptible power supply receives DC power from the battery 174 to supply AC power to the flash lamp 122. At this time, the output voltage maintains a constant voltage and a constant frequency. That is, in case of power failure, power is generated from the battery 174 to generate AC power, and when power is restored, power is supplied from the commercial power supply to the load. In the event of a power failure, the power supply side is short-circuited with many connected loads, so if the power failure is determined, the thyristor 173 cuts the power supply side. Therefore, after the battery 174 is charged, the epilator having such a circuit configuration can be used conveniently while being carried around.

The charging circuit of the driving unit described above is selected by way of example, and circuits of various configurations may be used to perform the same function.

The main body 110 is provided with a switch 144 for turning on / off the operation of the portable epilator, and the switch 144 is connected to the driving unit 140 of the main body 110.

In the portable epilator of the present invention having such a configuration, when the flash lamp 122, the filter 135, and the condenser lens 130 are used in combination, the hair removal apparatus can be depilated under the conditions most suitable for the skin and characteristics of each user. .

The portable epilator of the present invention having the above-described configuration is simple, can be manufactured in a small size, and can be manufactured for charging, so that the general user can easily use it anytime and anywhere without having to find a specialized institution. In addition, since the production cost is also low, there is an advantage that it is easy to disseminate as a means of self-management of ordinary users without any cost burden.

In addition, the portable epilator of the present invention has a cooling structure having two stages, that is, a space for the cooling water surrounding the outer circumferential surface of the reflector after primary cooling by air by constructing the flash lamp and the reflector spaced at regular intervals, which generate a lot of heat. It has a structure to cool secondly using the cooling water stored in the part. Therefore, there is an advantage that the portable hair removal device can be used stably for a certain time by providing the cooling means suitable for the compact structure.

Furthermore, in the present invention, the flash lamp is detachably configured so that the flash lamp can be easily replaced at any time as needed to improve the convenience of the device.
