Description

Skin treatment device

[0001] The present invention relates to a skin treatment device.

[0002] Generally, the basic structure of the skin consists of three layers: the epidermis, dermis, and subcutaneous tissue. The epidermis is located at the uppermost layer of the skin and serves to protect it from external stimuli, exhibiting keratinization and exfoliation. The dermis is situated below the epidermis; it is approximately seven times thicker and contains collagen and elastin, which are types of proteins. The dermis is responsible for important functions such as nutrient supply, secretion, and sensation. Subcutaneous tissue forms the skin's curves and functions to protect against external impacts while maintaining body temperature.

[0003] Meanwhile, wrinkles increase as the skin ages due to the loss of elasticity and flexibility, a decrease in moisture content, and reduced regenerative capacity. Additionally, the skin may sag in hot weather, and swelling or enlarged pores may occur due to various causes such as plastic surgery, dietary intake high in sodium, lack of sleep and exercise, and circulatory disorders.

[0004] Therefore, various medical and beauty devices are being released to prevent skin aging and wrinkles. For example, medical or beauty devices utilizing LEDs that emit wavelengths in the visible and infrared regions are effective for wrinkle improvement, skin regeneration, and acne treatment, while medical or beauty devices utilizing ultrasonic vibrations are effective for skin care.

[0005] The present invention provides a skin treatment device for treating skin and improving wrinkles.

[0006] One aspect of the present invention provides a skin treatment device comprising: a housing having an opening at the front; a heating unit including a base disposed inside the housing and having a plurality of protrusions on the front surface and a heating element for heating the base; a driving unit for linearly moving the heating unit so that the plurality of protrusions protrude to the outside of the housing through the opening or return to the inside of the housing; and a detachable member for detachably fixing the base at the front of the heating unit.

[0007] The skin treatment device according to the present invention allows for the replacement of a base having multiple protrusions for each skin treatment, and enables easy cleaning and convenient storage by separating the base after use. Of course, the scope of the present invention is not limited by these effects.

[0037]

[0038] FIG. 1 is a perspective view illustrating a skin treatment device according to one embodiment of the present invention, FIG. 2 is a perspective view illustrating the tip housing of FIG. 1 separated, FIG. 3 is a rear perspective view of FIG. 2, and FIG. 4 is a longitudinal cross-sectional view of FIG. 1.

[0039] Referring to FIGS. 1 to 4, a skin treatment device (100) according to one embodiment of the present invention may include a housing (110), a heating unit (120), a driving unit (130), and a detachable member (140).

[0040] The skin treatment device (100) can come into contact with the user's skin and heat the tissue of the skin in contact. In the skin treatment device (100), a protrusion (121a) of a heating unit (120) having a predetermined temperature comes into contact with and separates from the skin in an instant, and at this time, the skin may be vaporized or burns may be generated by the heat transferred from the skin treatment device (100). The vaporization or burns generated on the skin may be regenerated by the tissue's regenerative ability, thereby treating the skin or improving wrinkles on the skin.

[0041] The skin treatment device (100) can apply pressure to the skin by coming into contact with the user's skin. The skin treatment device (100) has a protrusion (121a) of a heating unit (120) having a predetermined temperature that moves forward, heating the skin while simultaneously applying pressure. At this time, the skin tissue is damaged by the heat and pressure. Subsequently, the damaged skin tissue is regenerated by the skin's regenerative ability, so that the skin can be treated or wrinkles on the skin can be improved.

[0042] The housing (110) forms the exterior of the skin treatment device (100) and may have an internal space in which other parts can be placed.

[0043] The housing (110) may have an opening (111a) at one end through which the front portion of the heating unit (120) is exposed. The projection (121a) of the heating unit (120) may be exposed to the outside through the opening (111a). The size of the opening (111a) may be set according to the size of the front portion of the heating unit (120) exposed through the opening (111a).

[0044] In the non-operating retracted position, the heating unit (120) is positioned at the rear of the opening (111a) of the housing (110). The projection (121a) of the heating unit (120) is positioned inside the opening (111a). Referring to FIG. 4, the projection (121a) of the heating unit (120) has a position retracted by a size d1 from the opening (111a).

[0045] In the operating forward position, the heating unit (120) is positioned in front of the opening (111a) of the housing (110). The projection (121a) of the heating unit (120) protrudes outward from the opening (111a). Referring to FIG. 4, the projection (121a) of the heating unit (120) has a position advanced by a size d2 from the opening (111a).

[0046] For example, the heating unit (120) may be set so that d2 in the forward position is smaller than d1 in the backward position.

[0047] When the heating unit (120) is in operation, the protrusion (121a) can advance by the sum of d1 and d2, and when the heating unit (120) is not in operation, the protrusion (121a) can retract by the distance advanced, and when the heating unit (120) is not in operation, it can be located in the internal space of the housing (110) to increase safety and portability.

[0048] The heating unit (120) can be moved linearly forward and backward through the driving unit (130), and the forward and backward distances of the protrusion (121a) correspond to the size of the linear forward and backward movement of the heating unit (120).

[0049] The housing (110) can be configured in various ways depending on the operating method of the skin treatment device (110). For example, the housing (110) may be a roughly column-shaped handpiece or a gun-shaped handpiece having a handle. However, for convenience of explanation, the following description will focus on an embodiment having a gun-shaped appearance.

[0050] The housing (110) may include a tip housing (111) and a main body housing (112).

[0051] The tip housing (111) may have an open front and rear and an internal space communicating with the open front and rear. The internal space may be formed in a shape in which the cross-sectional area gradually decreases from the rear to the front.

[0052] The projection (121a) of the heating unit (120) can be exposed to the outside through the opening (111a) formed at the front of the tip housing (111), and the rear part of the top housing (111) can be combined with the front part of the main body housing (112) so that the internal space can be communicated with each other.

[0053] The main body housing (112) may have a two-piece structure that can be separated and combined, and when combined, it may have a gun shape in which an opening (112a) is formed at the front, an internal space in which parts can be placed is formed, and a handle portion (112b) is formed at the bottom. However, for the convenience of explaining other configurations, the main body housing (112) combined as a one-piece will be described as the main embodiment.

[0054] The handle portion (112b) of the main body housing (112) may have an open bottom, and a power connection portion (112c) through which a main power line (not shown) is drawn out may be provided.

[0055] Although not described in detail, the skin treatment device (100) according to the present invention may receive external power via a wired method, but is not limited thereto, and may also receive power via a power charging method of an internal battery. In the case of a power charging method of an internal battery, the power connection part (112c) may be removed from the handle part (112b), and a port for charging power to the internal battery may be placed on the handle part (112b).

[0056] The rear portion of the tip housing (111) can be mutually detachably coupled to the front portion of the main body housing (112) through magnetic force.

[0057] To this end, a rim portion (112d) may be formed on the inner front surface of the main body housing (112), and a magnet (113) may be disposed on the rim portion (112d), and a detachable portion (111b) that is magnetically coupled to the magnet (113) may be disposed on the inner rear surface of the tip housing (111).

[0058] The magnet (113) can be formed in a roughly square shape, but is not limited thereto and can have various shapes such as elliptical and circular.

[0059] The detachable part (111b) can be formed in the shape of a bar having a length in the front-rear direction of the tip housing (111) and can be formed of a material attached to the magnet (113).

[0060] The end of the detachable part (111b) can be detachably attached to the front of the magnet (113) via magnetic force, and the rear part of the tip housing (111) can be detachably coupled to the front part of the main body housing (112).

[0061] At this time, the detachable part (111b) may include a first detachable part (111b-1) and a second detachable part (111b-2). The end of the first detachable part (111b-1) may be attached to the front surface of the magnet (113), and the second detachable part (111b-2) may be attached to wrap around both sides of the magnet (113).

[0062] By attaching the first detachable part (111b-1) to the front of the magnet (113) and the second detachable part (111b-2) to both sides of the magnet (113), the tip housing (111) can be connected to the main body housing (112) more accurately and stably. In addition, since no separate fastening member is required, the tip housing (111) and the main body housing (112) can be separated and connected more easily.

[0063] FIG. 5 is a partial perspective view illustrating a heating unit of a skin treatment device according to an embodiment of the present invention, FIG. 6 is a perspective view illustrating the base and heating element of the heating unit of FIG. 5 from the rear side, FIG. 7 is an enlarged perspective view of section 'A' of FIG. 5, FIG. 8 is a cross-sectional view along line II of FIG. 7, and FIG. 9 is a cross-sectional view illustrating the state in which the locking groove of the detachable member in FIG. 8 is released from the locking projection of the base.

[0064] Referring to FIGS. 4 to 6, the heating unit (120) may include a base (121), a heating element (122), a heater pad (123), a spacer (124), an elastic member (125), a driving connector (126), a substrate (127), and a case (128).

[0065] The base (121) has a front surface and a rear surface and may have a roughly plate-like shape. A plurality of protrusions (121a) may be formed on the front surface of the base (121), and the base (121) may have a predetermined thickness to support the plurality of protrusions (121a).

[0066] A base (121) including a plurality of protrusions (121a) may be formed of a ceramic material. By being formed of a ceramic material, the base (121) including a plurality of protrusions (121a) can be heated by rapidly receiving heat from a heating element (122). In addition, since ceramic is a biocompatible material, it can minimize skin irritation upon contact with the plurality of protrusions (121a) and enhance antibacterial properties, thereby improving skin treatment and wrinkle improvement effects.

[0067] Multiple protrusions (121a) can be placed on the front surface of the base (121) and can transmit heat and pressure in contact with the skin.

[0068] Each of the multiple protrusions (121a) may have a pyramid shape with a pointed tip, but is not limited thereto, and may be formed in various shapes with a pointed tip, such as a cone shape, for example.

[0069] The plurality of protrusions (121a) can be configured in various ways depending on the area of ​​skin treatment or the use of the skin treatment device (100). In the drawing, the plurality of protrusions (121a) are shown having an N×N square arrangement, but this is not limited thereto and can be configured in various ways.

[0070] A plurality of protrusions (121a) can be formed integrally with the base (121) by etching a portion of the base (121). Since the base (121) and the plurality of protrusions (121a) are formed integrally, the pressure can be evenly distributed when the plurality of protrusions (121a) come into contact with the skin.

[0071] A heating element (122) may be placed on the rear side of the base (121). An insertion groove (121b) may be formed on the rear side of the base (121), and a heating element (122) may be inserted into the insertion groove (121b).

[0072] Since the heating element (122) is inserted into the insertion groove (121b), the front-to-back size of the heating unit (120) can be reduced by the thickness of the heating element (122). As the front-to-back size of the heating unit (120) is reduced, the skin treatment device (100) can be miniaturized and manufacturing costs can be reduced.

[0073] Since the heating element (122) is inserted into the insertion groove (121b), the insertion groove (121b) may have a structure that is in close contact with the side as well as the front of the heating element (122). Since the heating element (122) is in close contact with the base (121) not only on the front but also on the side, the contact area can be increased to improve heat transfer efficiency. As the heat transfer efficiency from the heating element (122) to the base (121) is increased, the base (121) can be heated more quickly.

[0074] The heating element (122) may be made of, for example, a ceramic heater. Since the heating element (122) is made of a ceramic heater, it can be heated quickly with rapid heating, and electrical energy can be used efficiently through self-heat storage, safety can be increased by preventing excessive overheating, and the product weight can be reduced by being lightweight. The heating element (122) can generate heat by receiving electricity through a power line (122a). The power line (122a) of the heating element (122) can be connected to a substrate (127).

[0075] A heater pad (123) can be placed on the rear side of a heating element (122). The heater pad (123) can prevent internal components from being damaged by heat by minimizing the transfer of heat generated from the heating element (122) to the rear side opposite the base (121).

[0076] Since the heater pad (123) blocks heat moving to the rear, the heat generated from the heating element (122) can be transferred only to the multiple protrusions (121a). The heater pad (123) prevents heat loss and can increase the heat transfer efficiency.

[0077] A spacer (124) can be placed on the rear of the heater pad (123). An insertion groove (not shown) may be formed on the rear of the heater pad (123), and a front portion of the spacer (124) may be inserted into the insertion groove.

[0078] Since a portion of the front of the spacer (124) is inserted into an insertion groove (not shown), the size of the spacer (124) can be reduced by the size of the spacer (124) being inserted. Additionally, the spacer (124) can move integrally with the heater pad (123), so the heating unit (120) can move linearly more stably.

[0079] The elastic member (125) can elastically support the base (121), the heating element (122), and the heater pad (123) in response to external pressure applied to the plurality of protrusions (121a).

[0080] The elastic member (125) may be made of, for example, a compression coil spring, and a front portion of the elastic member (125) may be inserted and supported on the rear side of the spacer (124), and a rear portion of the elastic member (125) may be inserted and supported on the front support portion (126a) of the drive connector (126).

[0081] The elastic member (125) is supported at both the front and rear sides by an insertion method, thereby stably and elastically supporting the base (121), heating element (122), and heater pad (123) during linear movement of the heating unit (120).

[0082] The drive connector (126) is positioned at the rear end of the heating unit (120) and can be connected to the linear rod (131) of the drive unit (130). The linear rod (131) can be inserted and supported in the rear connection part (126b) of the drive connector (126).

[0083] For example, after the front end of the linear rod (131) is inserted into the rear connection part (126a), a fixing clamp (135) can be attached to the outer surface of the rear connection part (126a).

[0084] Therefore, when the linear rod (131) of the drive unit (130) moves linearly, the drive connector (126) moves linearly, and the entire heating unit (120) can move linearly.

[0085] The substrate (127) can be placed on the drive connector (126). For example, a step portion may be formed between the front support portion (126a) and the rear connection portion (126b) of the drive connector (126), and the substrate (127) may be fitted into and fixed to the step portion.

[0086] The substrate (127) is a type of connection board and is electrically connected to the control board (105) through input / output connector pins (not shown), and can serve as an intermediate medium when it is difficult to directly connect components of the heating unit (120) to the control board (105). The control board (105) is a type of main controller and is connected to each component of the skin treatment device (100), and can control the operation of each component. The input / output connector pins can be insulated with a material such as an insulator.

[0087] For example, the power line (122a) of the heating element (122) of the heating unit (120) can be connected to the substrate (127) and can be connected to the power supply unit (not shown) of the control board (105) through the input / output connector pin of the substrate (127), and the power supply unit of the control board (105) can apply electrical energy such as current to the power line (122a) through the input / output connector pin of the substrate (127).

[0088] The heating element (122) can be rapidly heated by receiving electrical energy from the power supply unit of the control board (105), and when the heating element (122) is heated, the plurality of protrusions (121a) of the base (121) can be rapidly heated.

[0089] The case (128) can form an exterior covering the heating unit (120), and, for example, can cover the spacer (124), elastic member (125), and driving connector (126).

[0090] The case (128) may have a two-piece structure in which the upper and lower parts can be separated and combined with each other. For example, the case (128) may consist of an upper case and a lower case that cover the upper and lower parts of the heating unit (120), respectively. In this case, the upper case and the lower case may be separated and combined with each other at the front side by a fastening member connection using a pipe screw (129), and at the rear side, may be separatedly connected to the upper and lower parts of the drive connector (126) through a fastening member, respectively. For example, the pipe screw (129) may be formed of a metal material having heat resistance.

[0091] A plurality of heat dissipation holes (128a) may be formed in the case (128). Heat generated inside the case (128) can be smoothly released to the outside of the case (128) through the plurality of heat dissipation holes (128a).

[0092] Referring to FIGS. 7 to 9, the detachable member (140) can detachably fix the base (121) to the front of the heating unit (120). That is, the base (121) can be detached from the heating unit (120) through the detachable member (140). Since the base (121) having a plurality of protrusions (121a) can be detached, the base (121) can be replaced each time skin treatment is performed, and the base (121) having a plurality of protrusions (121a) can be separated after use to facilitate cleaning and convenient storage.

[0093] For example, the detachable member (140) may include a leaf spring, one end of which is detachably fixed to the front of the heating unit (120), and the other end of which may be elastically hooked to the base (121).

[0094] That is, while one end of the detachable member (140) is fixed to the heating unit (120), the other end is engaged or disengaged from the base (121), thereby allowing the base (121) to be fixed to the heating unit (120) or separated from the heating unit (120).

[0095] At this time, the detachable member (140) may be arranged in multiple numbers on the upper and lower sides or on the left and right sides of the heating unit (120). In this embodiment, since the case (128) of the heating unit (120) has a two-piece structure divided into upper and lower parts, a structure is disclosed in which multiple members are arranged on the upper and lower sides of the case (128).

[0096] The detachable members (140) positioned on the upper and lower sides of the case (128) may have the same structure in which only their directions are opposite to each other and one end is fixed to the case (128) while the other end is elastically hooked onto the base (121).

[0097] That is, the detachable member (140) positioned on the upper or lower side of the case (128) has a structure in which one end is detachably fixed to the front upper or lower side of the case (128), and the other end is elastically hooked to the upper or lower side of the base (121).

[0098] In detail, one end of the detachable member (140) can be detachably fixed to the case (128) through a fastening member, and a locking groove (141) is formed at the other end of the detachable member (140), and a locking projection (121c) corresponding to the locking groove (141) can be formed on the base (121).

[0099] For example, the locking grooves (141) may be formed in multiple numbers on both sides of the other end of the detachable member (140), and the locking projections (121c) may be formed in multiple numbers on both sides of the upper side and both sides of the lower side of the base (121) to correspond to the locking grooves (141), but are not limited thereto. A single locking groove may be formed in the center of the other end of the detachable member (140), and a single locking projection may be formed in the center of the upper side and the center of the lower side of the base (121). In this embodiment, the detachable member (140) can be more stably fixed by elastically locking both sides of the other end to both sides of the upper side and both sides of the lower side of the base (121).

[0100] As shown in FIG. 8, a base (121) having a plurality of protrusions (121a) can be fixed by having a catch protrusion (121c) formed on the upper and lower sides catch in the catch groove (141) of the detachable member (140).

[0101] In this state, when the heating unit (120) moves linearly through the driving unit (130), the multiple protrusions (121a) of the base (121) instantly come into contact with and separate from the user's skin through the opening (111a).

[0102] At this time, the plurality of protrusions (121a) heated by the heating element (122) can generate vaporization or burns on the skin, and the vaporization or burns generated on the skin can be regenerated by the tissue's regenerative ability, thereby treating the skin or improving wrinkles on the skin.

[0103] After the treatment of the skin is completed, the base (121) having a plurality of protrusions (121a) can be easily separated from the heating unit (120) by operating the detachable member (140).

[0104] As illustrated in FIG. 9, when the other end of the detachable member (140) is moved to the outside of the base (121), the locking groove (141) can be separated from the locking projection (121c), and when the locking of the locking projection (121c) and the locking groove (141) is released, the base (121) can be moved forward to easily separate the base (121) from the heating unit (120).

[0105] The base (121), separated from the heating unit (120) by operating the detachable member (140), can be reattached and used after cleaning and can be conveniently stored. Of course, in the event of damage to the multiple protrusions (121a) or the base (121), the damaged base (121) can be separated and replaced with a new base.

[0106] Meanwhile, the rear surface of the locking projection (121c) formed on the base (121) may be formed as an inclined surface. The rear surface of the locking projection (121c) may be formed as an inclined surface that slopes downward toward the rear.

[0107] Since the rear surface of the catch projection (121c) is formed as an inclined surface, the base (121) can be moved more easily to the rear when external pressure is applied to the plurality of projections (121a).

[0108] That is, when the base (121) moves backward, the insertion groove (141) of the detachable member (140) moves along the rear inclined surface of the locking projection (121c), so the base (121) can be moved backward more easily.

[0109] At this time, the base (121) can be elastically moved forward and backward through the elastic force of the elastic member (125).

[0110] In addition, to secure the forward and backward movement distance of the base (121), it is preferable that the size of the insertion groove (141) of the detachable member (140) in the forward and backward direction be larger than the thickness of the locking projection (121c) of the base (121) in the forward and backward direction.

[0111] The scope of the present invention is not limited to the embodiments described above, and all scopes equivalent to or equivalently modified from the claims set forth below, as well as the claims set forth below, shall be considered to fall within the scope of the concept of the present invention.
