Description

  The present invention relates to a hair remover with improved operational safety. More specifically, a light irradiation device used for skin cosmetics using light rays, particularly a hair removal device, is convenient to use with improved portability, and only when the hair removal device adheres completely to the skin. When the hair remover is used, a protective device such as sunglasses is not required, and the hair remover has improved operational safety so as to prevent malfunction.

  Usually, a depilator is a device for removing body hair, hair, etc. grown on human skin. There are razors that shave body hair with a razor blade as a traditional hair remover, and a threshing-type forced hair remover that forcibly removes hair to remove roots.

  However, the traditional hair remover as described above forcibly removes the hair by a physical method, and the razor cannot remove the hair root and must continuously remove the hair. Therefore, there is a limit to performing complete hair removal, and forced hair removal equipment is inconvenient to use because it causes pain for the user during the hair removal process, and skin damage such as increase in hair follicle size There is a problem that causes.

  As a conventional technique relating to a hair removal device for solving the above-mentioned problems, “Heat” disclosed in Korean Patent Registration No. 10-0915371 (2009.08.27) (hereinafter referred to as Patent Document 1) is disclosed. There is a “deduction hair removal device”. The said patent document 1 is related with the hair removal device which removes the body hair which passes between the comb teeth of a hair removal part using a heat ray.

  However, the hair removal device of the above-mentioned Patent Document 1 not only causes skin damage due to high heat by direct contact with the skin, but also burns and removes body hair by heat, and complete removal of hair roots. Therefore, it is not effective in preventing the hair from growing again, and the hair is burned during the hair removal process.

  In order to solve the above-mentioned problems, there is a hair remover that removes hair using the wavelength of light. As a related art related to this, there is a “photo skin treatment device” disclosed in Korean Utility Model No. 20-0360150 specification (2004.08.17) (hereinafter referred to as Patent Document 2).

  The hair removal device of Patent Document 2 removes body hair with a hair removal handpiece that irradiates light with a wavelength of 560 nm to 1100 nm, and a separate body is provided for operating the handpiece, thus reducing portability. Therefore, it can be used only by specialized treatment institutions and the like, and there is a drawback that general users cannot easily use it.

  On the other hand, as another conventional technique, there is a “portable hair remover using an optical pulse” described in Korean Patent No. 10-0801376 (2008.01.29) (hereinafter referred to as Patent Document 3). is there.

  The hair removal device of Patent Document 3 removes body hair by a flash lamp installed in a hollow portion of a main body in order to irradiate a light pulse. At this time, the hair remover has a space formed in the main body so that cooling water is contained between the inner peripheral surface and the outer peripheral surface of the hollow portion of the hair remover, and eliminates heat generated during hair removal.

  However, since Patent Documents 2 and 3 are of a button operation type and are irradiated with a hair removal light beam (pulse), when the hair removal device is not in close contact with the skin for the purpose of hair removal, it malfunctions. There are cases where light rays are irradiated, and if the light rays are applied to the user's eyes, etc., it may cause damage to the retina. There is.

  In the description of the hair removal device with improved operational safety according to the present invention, if an approximate direction reference that is not strict for convenience is specified based on FIG. 1 and FIG. Determine the top, bottom, left and right as a reference.

  In particular, in FIG. 1, the front and back sides are specified with the light beam direction of the mounted light cartridge 20 irradiating the front surface, the front and the upper side, and the rear and the lower side are mixed for explanation, and other figures are concerned. Unless otherwise stated in the detailed description of the invention and the claims, the direction is specified and described according to this standard.

  Hereinafter, a hair removal device with improved operational safety according to the present invention will be described with reference to the accompanying drawings.

  First, as shown in FIGS. 1 to 5, the hair remover with improved operational safety according to the present invention is roughly divided into a main body 10, a light beam cartridge 20 that can be used interchangeably with the main body 10, and a cooling cartridge 30. Become.

  As shown in FIGS. 1 and 4, the main body 10 has a streamlined body so that a user can easily grip and use it, and a power supply means for operating the cartridge is provided inside the body. 16 and a first main board for controlling power supply are incorporated.

  Although not shown in the drawings, the main body includes a power button (not shown) for turning on / off the power, a light beam cartridge 20 and a cooling cartridge 30 (to be described later), and functions of each cartridge. A button part including a mode selection button (not shown) for operating the cartridge and an adjustment button (not shown) for adjusting the function of each cartridge is provided.

  Among these, the mode selection button selects a mode suitable for the cartridge function after fastening each cartridge so that the depilator is operated accordingly. That is, after the light cartridge 20 is mounted, the hair removal mode can be selected to remove the body hair, and after the cooling cartridge 30 is mounted, the cooling mode is selected to implement the cooling function. At this time, if the skin whitening mode is selected by the mode selection button while the light cartridge 20 is attached, the control unit adjusts the output of the light emitted from the light output unit 24 of the light cartridge 20 to remove the skin stratum corneum. Generates whitening, massage effect. The adjustment buttons can adjust the intensity of each function, that is, the output of the light beam irradiated in the hair removal mode, and the cooling intensity in the cooling mode.

  Such light output adjustment is performed so that the function applied to the skin differs depending on the frequency band of the light depending on the adjustment button. That is, if a high-frequency light beam is output by the adjustment button, the effect of skin massage and the effect of hair removal and exfoliation such as fluff are simultaneously applied to the hair follicle, and a low-frequency light beam is output. If this is done, acne and stains can be alleviated by skin massage, and a skin whitening effect can be obtained.

  Further, even when the cooling cartridge 30 is mounted, if the cooling function is used by the adjustment button, that is, if the cooling temperature is adjusted, the hair remover of the present invention can be used for skin beauty by cooling massage.

  The button unit further includes a first display (not shown) for displaying the mode selected by the operation of the mode selection button and a second display (not shown) for displaying the strength by the operation of the adjustment button. Can be provided.

  Accordingly, the hair remover of the present invention functions not only as a simple hair remover but also as a multipurpose light tone irradiator that can be expected to have various skin cosmetic effects by the light output, and is removed from the conventional simple hair remover. Various functions can be provided as a light tone irradiator for skin beauty.

  In particular, according to the present invention, the button unit is not provided with a light beam irradiation button. This is because the control unit controls the light beam irradiation by a skin detection sensor 27 to be described later. This is a configuration for preventing the light beam from being irradiated to a part other than the skin to be removed.

  1 to 4, the main body 10 of the present invention further includes power supply means 16 for supplying power. In order to improve portability, which is one of the main objects of the present invention, a built-in rechargeable battery that allows external power to be charged and used inside the main body 10 as the power supply means 16. It is preferable to connect the plug to the external power socket together with the charging of the rechargeable battery and directly apply the external power to use the hair remover, so that the external power can be used using various types of plugs. More preferably, a USB terminal (not shown) connected to the rechargeable battery is provided on one side.

  On the other hand, as shown in FIGS. 4 and 5, a mounting portion 11 for attaching and detaching the cartridge is further provided in front of the main body 10 of the present invention.

  The mounting portion 11 can be formed integrally with the main body 10, but is coupled to the front of the main body 10 as shown in FIGS. 1, 4, and 5 in order to ensure the ease of manufacturing the air circulation means 14 described later. The first mounting member 12 having a first corresponding fastening portion 12a to which the first fastening portion 31a of the cooling cartridge 30 is fastened, and the second fastening portion of the light cartridge 20 coupled to the front of the first mounting member 12 It consists of the 2nd mounting member 13 which has the 2nd corresponding | compatible fastening part 13a to which 21a is fastened.

  First, as shown in FIGS. 1 and 2, the light beam cartridge 20 of the present invention is a cylindrical member provided with the second fastening portion 21a along the peripheral edge of the lower outer end portion. It comprises a first body 21 to which a first substrate 29 (not shown) is coupled, and a first cap member 22 coupled to the front of the first body 21.

  The first substrate 29 includes various chips and elements (not shown) as a control unit, a light beam output unit 24 is electrically connected to the front, and the light beam output unit 24 controls the light beam by control of the control unit. Is output.

  In the present invention, the concept of the light beam output from the light lamp 23 is a concept that includes intangible energy used for all skin cosmetics such as hair removal using a light beam and skin massage. There are a laser, an optical pulse (IPL; Intensive Pulse Light), and the like. For convenience of explanation, light rays used for the purpose of hair removal will be representatively described below.

  The ultrasonic hair removal method is a method that removes the hair roots by irradiating the skin with ultrasonic waves used in various operations and treatments. The laser hair removal method is a specific wavelength band emitted from a specific medium. This is a method for removing the hair roots of the body hair, and the hair removal method using a light pulse is a method for removing the hair roots by emitting light having a certain wavelength band in the form of periodic pulses. .

  As described above, the hair removal method using various forms of light is typically a method of destroying the hair root of the body hair by changing to heat energy while the light is absorbed by the melanin pigment of the skin.

  Further, a support member 25 is coupled to the first substrate 29, and a light projection panel 25A capable of transmitting light is coupled via the support member 25, and is provided in front of the light output unit 24. It is embodied in the light lamp 23 together with the output unit 24.

  The light lamp 23 is provided with a skin sensor 27 along the front edge, and the controller controls to irradiate light only when the skin is detected over the entire part of the skin sensor 27. .

  That is, as described above, the present invention does not include a separate light irradiation button, and automatically applies light only when the first cap member 22 of the light cartridge 20 is completely in close contact with the skin by the skin sensor 27. In this case, it is possible to fundamentally block the application of light to a part other than the skin to be depilated due to user error or unintentional operation of the hair removal device.

  In particular, the present invention includes the skin sensor 27 along the front edge of the support member 25 to which the light lamp 23, more specifically, the light projecting panel 25A is coupled. By irradiating light only when the light is detected, the light output holes 22A of the first cap member 22 are not completely in close contact with the skin due to the structure, that is, the light output holes 22A are only partially in contact with the skin. Or the part other than the skin where the light beam should be removed, such as when the light output hole 22A is all in contact with the skin but not completely in contact and the separation distance between the skin and the skin sensor 27 is not uniform. By fundamentally blocking the possibility of irradiating the light, it is possible to prevent light irradiation due to malfunction and to prevent injury due to light.

  In addition, in order to more stably realize the operation safety of the hair removal device, the control unit does not immediately irradiate light when the skin is detected over the entire part of the skin detection sensor 27, and the skin Control is performed so that a light beam is emitted from the light beam output unit 24 only when the sensing state is maintained within a certain time (about 1 to 2 seconds).

  As shown in FIG. 2, the present invention introduces a skin detection sensor 27 including a conductive plate 28 for stable operation of the skin detection sensor 27.

  The conductive plate 28 is provided along the edge of the light lamp 23, and a pair of grounding portions 28 a that are partially broken and bent backward are coupled to the first substrate 29. It is electrically connected by. In the conductive plate 28, when a certain distance is maintained with respect to the skin over the entire part, the capacitance generated from the human body is transmitted to the whole part of the conductive plate as it is, and the entire conductive plate is transferred within a predetermined time. If the capacitance changes, the control unit senses this and recognizes that the skin is completely adhered, and controls the light output unit 24 to output a light beam.

  The conductive plate 28, that is, the skin detection sensor 27 is provided to be covered by the inner wall 22 </ b> A of the light output hole 22 </ b> A of the first cap member 22. Such an inner wall 22A is formed so that the conductive plate 28 has a maximum height for recognizing skin contact sensing. That is, when the height of the light output hole 22A is set to the maximum distance at which the electric charge of the conductive plate 28 is activated by the magnetic field of the skin, even if a part of the light output hole 22A does not adhere to the skin, Since the current does not flow through the conductive plate 28, and thus the power is not supplied in such a case, the control unit controls the light beam not to be output so that the light beam is irradiated to the outside of the light beam output hole 22A. It becomes possible to cut off fundamentally.

  Further, since the conductive plate 28 is covered with the inner wall 22A of the light beam output hole 22A, the skin does not directly contact the conductive plate 28, so that the conductive plate 28 can be prevented from being oxidized. When the skin is too close, malfunctions and malfunctions caused by overheating due to overcurrent flow can be prevented.

  Below, based on FIGS. 2-5, the specific structure of the said main body 10, the light beam cartridge 20, and a Coolie cartridge and the attachment / detachment structure with respect to the main body 10 are demonstrated more concretely.

  First, as shown in FIG. 4, a mounting portion 11 for attaching and detaching the cartridge is further provided in front of the main body 10 of the present invention. The mounting portion 11 can be formed integrally with the main body 10, but is coupled to the front of the main body 10 in order to ensure the ease of manufacturing the air circulation means 14 described later, and the first fastening portion of the cooling cartridge 30 (see FIG. 3). A first mounting member 12 having a first corresponding fastening portion 12a to which 31a is fastened and a second fastening portion 21a of the light beam cartridge 20 (see FIG. 2) are fastened in front of the first mounting member 12. It consists of the 2nd mounting member 13 with the 2nd corresponding | compatible fastening part 13a.

  As shown in FIGS. 1 and 2, the light cartridge 20 of the present invention includes a first body 21 having the second fastening portion 21 a along the periphery of the lower outer end, and the first body 21. The first cap member 22 is coupled to the first cap member 22.

  As shown in FIGS. 2 and 4, the second fastening part 21a of the light beam cartridge 20 and the second corresponding fastening part 13a of the mounting part 11 are embodied by a known fastening form, that is, male and female fastening grooves and protrusions. it can. For example, a one-touch press attachment / detachment method in which the light cartridge 20 is attached / detached simply by pushing the light cartridge 20 into the attachment portion 11 of the main body 10, or a rotation attachment / detachment method in which attachment / detachment is performed by rotation with the light cartridge 20 attached to the attachment portion 11 of the main body 10. A button attaching / detaching method in which the light cartridge 20 is attached to and detached from the attachment portion 11 of the main body 10 with a separate attachment button can be considered. The attachment and detachment of the light cartridge 20 and the main body 10 implemented in this manner are described later. The present invention can be similarly applied to the attachment and detachment of 30 and the main body 10.

  A first substrate 29 having a light lamp 23 is provided on the front surface of the first body 21. The first substrate 29 includes various chips and elements constituting a control unit, and is configured such that a terminal 29A for power supply and electrical connection with the main substrate 15 of the main body 10 protrudes backward, The first body 21 is exposed behind the first body 21 through the through hole 21 c of the first body 21.

  The front surface of the second mounting member 13 includes a socket portion 13b into which the terminal 29A is inserted and an insertion groove 13c into which the guide wall body 21b of the first body 21 is inserted. The socket portion 13b is electrically connected to the main board 15 or the power supply means 16 via an electric wire (not shown).

  Further, a temperature sensor (not shown) is further provided on one side of the front or rear surface of the first substrate 29. The temperature detection sensor is provided to be exposed in the direction of the light beam output unit 24, that is, in front of the first substrate 29, and senses the temperature of the first substrate 29 and the light lamp 23 in real time. Prevent overheating due to use and prevent malfunction of the epilator. More preferably, the temperature detection sensor is connected to the controller and automatically adjusts the output intensity of the light according to the detected temperature.

  The present invention employs a compact temperature sensing sensor attached to the first substrate 29, thereby reducing space constraints in product design. Two or more temperature detection sensors may be provided on the first substrate 29, and a plurality of temperature detection sensors may be installed at many locations on the first substrate 29 to detect an omnidirectional temperature rise in real time. be able to.

  Meanwhile, a light lamp 23 is mounted on the front surface of the first substrate 29. The light lamp 23 includes a light output unit 24 and a light projecting panel 25A. The light beam output unit 24 is electrically connected to the first substrate 29, and a reflection guide 26 having a front bent portion 26 </ b> A is disposed between the first substrate 29 and the light beam output unit 24. The light beam output from the output unit 24 is irradiated forward.

  A light projecting panel 25A having a light projecting property is coupled to the support member 25 mounted on the first substrate 29 in front of the light beam output unit 24, so that the output light beam passes through the light projecting panel 25A. It passes through and is irradiated through the light output hole 22A of the first cap member 22.

  The light projecting panel 25A is coupled to a mounting hole of the support member 25 by a hook coupling method, and the support member 25 is engaged with an engagement hole 25b as a skin detection sensor 27 at the front edge for coupling the conductive plate 28. A protrusion 25A is provided. The conductive plate 28 is connected to and connected to the first substrate 29 in a state where both the grounding portions 28a are bent rearward and engaged with the engaging protrusions 25A, and the conductive plate 28 is bent and protruded rearward. By engaging the stop protrusion 28 b with the engagement hole 25 b, the conductive plate 28 is fixed to the support member 25, that is, the front edge of the light lamp 23.

  The first cap member 22 is coupled to the front surface of the first body 21 so as to cover the first substrate 29 and the light lamp 23, and a central light output hole 22A is formed to correspond to the light projecting panel 25A. As a result, a light beam is irradiated forward. The first cap member 22 includes a large number of air passages 22b communicating with each other, and the light lamp 23 is cooled by air circulation.

  In addition, the control unit automatically limits the number of times the light source is output so that no light is output when it is used in excess, thereby preventing skin damage caused by excessive use of the hair remover. When the hair remover is used excessively, the skin is immediately cooled by a cooling cartridge 30 described later.

  Accordingly, after hair removal by irradiation with light, it is necessary to take appropriate subsequent measures to cool and stabilize the user's skin to eliminate irritation. In the present invention, the cooling cartridge 30 manufactured by the design of the heat dissipation structure that realizes the cooling function by absorbing the heat released by the skin contact and releasing it from the hair remover is replaceably mounted on the mounting portion 11 of the main body 10. The above problems were solved by making it possible to use them.

  To this end, as shown in FIGS. 1, 3 and 4, the cooling cartridge 30 includes a second body 31 having the first fastening portion 31a along the periphery of the lower outer end, and the second body 31. The second cap member 32 is coupled to the front of the body 31 and includes a contact heat absorbing portion 32A on the front surface.

  The contact heat absorption part 32A is preferably made of a material excellent in heat transfer efficiency, and a plurality of protrusions projecting rearward in order to dissipate and cool the heat transmitted from the contact heat absorption part 32A in front of the second body 31. The cooling member 33 having the radiating blade 33A is provided. The cooling member 33 is manufactured from a thermoelectric element, and can cool the skin by heat absorption and heat dissipation by heat transfer.

  As a typical thermoelectric element, there is a Peltier element. This is an element that uses the Peltier effect in which heat is absorbed by one metal and heat is released by the other metal when electricity is applied to both of them while joining both ends of different metals. It refers to elements used in many industrial fields such as cooling fans and coolers.

  In the present invention, like the Peltier element, the cooling member 33 excellent in heat absorption and heat transfer contacts the contact heat absorption part 32A of the second cap member 32, and the contact heat absorption part 32A of the second cap member 32 cools. So that the heat radiating blade 33A of the cooling member 33 provided on the opposite side, that is, the inner rear side of the second cap member 32 functions as a heat radiating portion, so that the contact heat absorbing portion 32A is in contact with the skin. Then, the absorbed heat is dissipated and eliminated backward through the cooling member 33 to cool the skin, thereby realizing the effect of skin progress.

  In addition, the cooling cartridge 30 of the present invention includes a large number of air passages 32 penetrating the outer peripheral surface of the second cap member 32 and can improve the heat dissipation effect by air circulation.

  In addition, when a thermoelectric element such as a Peltier element is used as the cooling member 33, power must be supplied. Therefore, a second substrate having a terminal 39A for supplying power is provided in front of the second body 31. 39, the power supply and cooling control of the cooling member 33 are performed by the second substrate 39, and the configuration by the connection of the terminal 39A and the socket portion 13b of the main body 10 is the same as that of the light beam cartridge 20.

  Further, in order to secure the maximum contact area of the contact heat absorbing portion 32A of the second cap member 32 and to improve the heat radiation effect by the cooling fan 19 and the air circulating means 14 described later, the cooling cartridge 30 is provided with the second cap member 32. The first fastening part 31a provided at the lower end of the second body 31 is connected to the second corresponding fastening part 13a of the mounting part 11. The cooling cartridge 30 and the main body 10 are attached and detached in a manner that is fastened to the first corresponding fastening portion 12a.

  As a result, the second body 31 includes a second housing space 31a for housing the second mounting member 13 of the main body 10 at the rear, and other configurations such as a through hole 31c and a guide wall body 31b of the second body 31. Is similar to the light beam cartridge 20.

  The diameter of the cooling member 33 and the contact heat absorption part 32A built in the cooling cartridge 30 having such a structure can be ensured to the maximum, and the functions of heat absorption and heat dissipation by contact can be maximized.

  Next, according to the present invention, as shown in FIGS. 4 and 5, the light cartridge 20 and the cooling cartridge 30 can be constantly cooled by introducing a cooling fan 13 </ b> A into the mounting portion 11.

  In the drawing, for convenience of explanation, the cooling fan 13A is shown as a box-like member. However, the essence of the cooling fan 13A is blown into the internal space of the second mounting member 13 where the cartridges 20 and 30 are in contact with each other. It is the member which cools.

  Therefore, the cooling fan 13A is a well-known member for blowing air, and there is typically a cooling member 33 having a propeller formed so as to blow air to one side. It means all forms of members that eliminate the heat generated by each cartridge, more broadly, the heat generated inside the main body 10.

  The cooling fan 13 </ b> A is preferably fixedly installed on the mounting portion 11, more specifically on the upper surface of the partition plate (not indicated) of the first mounting member 12. Accordingly, the second mounting member 13 not only functions as the mounting portion 11 of the light beam cartridge 20 but also functions as a housing that prevents the cooling fan 13A from being exposed to the outside.

  Although not shown in the drawing, the cooling fan 13A operates by receiving power from the rechargeable battery of the main body 10, is electrically connected to the main board 15, and the cooling fan 13A is interlocked when each cartridge is operated. A method of operating the cooling fan 13A by a separate button or a separate button can be considered.

  Next, in order to further improve the cooling effect by the cooling fan 13A, the present invention introduces a heat dissipation structure design that circulates air through the mounting portion 11. For this purpose, as shown in FIGS. 4 and 5, the mounting portion 11 of the present invention further includes an air circulation means 14 that circulates air inside and outside.

  First, the air circulation means 14 includes an air circulation hole 14 b penetrating through the partition plate of the first mounting member 12. The air circulation hole 14b is configured such that the center of the partition plate is perforated, and the internal space of the first mounting member 12 and the second mounting member 13 communicates with each other via the air circulation hole 14b. Air can circulate between the members to improve the function of eliminating the heat generation of the cartridge. In some cases, there is an electric wire (not shown) connecting the main board or the power supply means to the socket part through the air circulation hole. Can be used to pass through.

  As shown in FIGS. 4 and 5, the air circulation means 14 includes a plurality of air circulation holes 14 a penetratingly provided on the outer peripheral surface of the first mounting member 12. The air circulation hole 14a can be configured in such a manner that a large number of slit-like air circulation holes are arranged along the outer peripheral surface, but in order to maximize the function of air circulation inside and outside the mounting portion 11, it is shown in the drawings. As described above, a method in which one or more rectangular air circulation holes 14 a are perforated along the outer peripheral surface edge of the first mounting member 12 is more preferable.

  Therefore, when the cooling fan 13A is activated, the air in the first mounting member 12 is sucked through the air circulation hole 14b and is blown and circulated upward. With such a circulation structure, external air is supplied to the inside through the air circulation hole 14 a, so that new air at room temperature is constantly circulated inside the mounting portion 11 and cooled.

  At this time, the cooling efficiency can be further improved by providing a large number of auxiliary circulation holes (not shown) penetrating in the vertical direction and communicating with the air passage holes 32 inside the cartridge, particularly the cooling cartridge 30.

  Further, as shown in FIG. 5, the mounting portion 11 of the present invention includes an inclined guide portion 14 </ b> A that protrudes from the bottom edge of the first mounting member 12 toward the upper center, thereby providing an air circulation hole. The external air flowing in through 14a is guided more smoothly into the cooling fan 13A.

  That is, the inclined guide portion 14A is a conical member provided inside the first mounting member 12, and is formed so as to incline toward the center upper side from the side wall where the air circulation hole 14a is formed. Since the external air sucked into the interior is guided upward while being in contact with the inclined guide portion 14A, the efficiency of inflow of air into the second mounting member 13 is improved.

  Further, the inclined guide portion 14A is not only a function of guiding external air but also a material that is efficient for heat transfer, such as the contact heat absorbing portion 32A of the cooling cartridge 30, in order to improve the cooling efficiency of the circulated air. (For example, a thermoelectric element).

  Therefore, the present invention not only effectively eliminates the internal heat generation due to the use of the hair remover, but also constantly cools the thermoelectric element (contact heat absorbing portion 32A) of the cooling cartridge 30, thereby improving the cooling performance of the cooling cartridge 30. It can be maximized.

  In the above description of the present invention, the hair removal device having a specific shape and structure and improved operational stability has been mainly described with reference to the accompanying drawings. However, the present invention is variously modified, changed, and replaced by those skilled in the art. Such modifications, changes and substitutions should be construed as belonging to the protection scope of the present invention.

  The present invention can be applied to a hair remover with improved operational safety so that a protective device such as sunglasses is not required when using the hair remover, and malfunction is prevented.
