[0106] FIG. 1 is a perspective view illustrating an embodiment of a skin beauty device including an embodiment of a skin cleansing handpiece (100) according to the present invention, and FIG. 2 and FIG. 3 are cross-sectional views illustrating an embodiment of a skin cleansing handpiece (100) according to the present invention.

[0107] An embodiment of a handpiece (100) for skin cleansing according to the present invention is described in detail below with reference to FIGS. 1 to 3.

[0108] One embodiment of the skin cleansing handpiece (100) according to the present invention includes a cleansing handpiece casing part (110), and the cleansing handpiece casing part (110) is formed in a shape including a handle that can be held and used by a practitioner.

[0109] And, a cleaning solution discharge tube (120) for supplying cleaning solution to the user's skin is provided protrudingly at the tip of the cleaning handpiece casing (110).

[0110] A cleaning liquid discharge pipe portion (120) is coupled with a cleaning skin contact portion (130) that comes into contact with the skin, and the cleaning skin contact portion (130) includes a rotation guide portion (131a) in which the cleaning liquid discharge pipe portion (120) is inserted and coupled internally and is positioned to rotate around the cleaning liquid discharge pipe portion (120).

[0111] Inside the cleaning handpiece casing (110), a cleaning rotating part (140) is located that is connected to the cleaning skin contact part (130) and rotates the cleaning skin contact part (130).

[0112] The skin contact part (130) for cleaning is detachably coupled to the rotating part (140) for cleaning and can be used by periodically replacing it.

[0113] The skin contact part (130) for cleaning is a part that comes into direct contact with the user's skin, and is replaced after one use for hygienic use.

[0114] The skin contact portion (130) for cleaning can be manufactured with different sizes depending on the body part being treated.

[0115] For example, the cleansing skin contact part (130) is divided into a face skin contact part (130a) and a body skin contact part (130b), and when the treatment area is the face, the treatment is performed using the face skin contact part (130a), and when the treatment area is the body, the treatment is performed using the body skin contact part (130b).

[0116] The cleaning skin contact portion (130) is detachably coupled to the cleaning rotating portion (140) and includes a mounting housing member (131) equipped with a rotating guide tube portion (131a) and a skin contact member (132) provided on the lower surface of the mounting housing member (131) and made of an elastic material to come into contact with the skin.

[0117] The skin contact member (132) may be a brush member made of an elastic material such as silicone, or a block member formed of a porous synthetic resin material such as a sponge.

[0118] The skin contact member (132) is positioned to protrude downward from the end of the cleaning liquid discharge pipe (120), so that the surface can come into contact with the skin without the cleaning liquid discharge pipe (120) touching the skin.

[0119] In addition, it can be manufactured using various known materials that come into contact with the skin and are used for cleansing, such as cotton pads, so further detailed explanations are omitted.

[0120] The skin contact portion (130) for cleaning has a cleaning liquid discharge portion (120) inserted into a rotating guide tube portion (131a), and the cleaning liquid discharge portion (120) is positioned so that it protrudes toward the lower end of the rotating guide tube portion (131a) through it, so that it can be positioned as close as possible to the skin.

[0121] The cleaning liquid discharge tube (120) is positioned so that its end side protrudes toward the lower side of the rotating guide tube (131a), positioned as close as possible to the skin, so that when supplying cleaning liquid to the skin, the cleaning liquid can be supplied stably without splashing as much as possible.

[0122] In addition, the cleaning liquid discharge pipe (120) penetrates the interior of the rotating guide pipe (131a) so that the rotating guide pipe (131a), i.e., the mounting housing member (131), is rotatably coupled and serves as the rotation axis of the mounting housing member (131).

[0123] The mounting housing member (131) is detachably coupled to the cleaning rotating part (140) as the cleaning liquid discharge pipe (120) penetrates into the interior of the rotating guide pipe (131a), and rotates around the cleaning liquid discharge pipe (120) by receiving rotational force from the cleaning rotating part (140).

[0124] The cleaning rotary part (140) includes a first rotary gear member (141) which is positioned rotatably around the cleaning liquid discharge pipe (120) and detachably coupled to a mounting housing member (131) through which the cleaning liquid discharge pipe (120) passes inside the cleaning handpiece casing part (110), a second rotary gear member (142) which is provided to mesh with the first rotary gear member (141) and is positioned rotatably inside the cleaning handpiece casing part (110), and a cleaning rotary motor (143) that rotates the second rotary gear member (142).

[0125] A second rotating gear member (142) is mounted on the shaft of the cleaning rotary motor (143), and the second rotating gear member (142) is positioned to mesh with the first rotating gear member (141) within the cleaning handpiece casing (110) to transmit rotational force to the first rotating gear member (141), thereby rotating the first rotating gear member (141) around the cleaning liquid discharge pipe (120).

[0126] Additionally, the first rotary gear member (141) is positioned to protrude toward the tip of the cleaning handpiece casing part (110) and has a housing coupling part (141a) to which the mounting housing member (131) is detachably coupled.

[0127] The housing coupling portion (141a) protrudes toward the front end of the cleaning hand casing portion through a hollow portion through which the cleaning liquid discharge pipe portion (120) passes, and is provided with a catch insertion groove portion (141b) on its outer surface.

[0128] Additionally, a coupling projection (131b) that is detachably coupled to a housing coupling portion (141a) is provided protruding from the upper surface of the mounting housing member (131), and a locking projection (131c) that is detachably coupled to a locking insertion groove (141b) of the housing coupling portion (141a) is provided protruding from the inner surface of the coupling projection (131b).

[0129] The coupling projection (131b) has elasticity and opens when pressed beyond a preset force, allowing the locking projection (131c) to be inserted into the locking insertion groove (141b) and then returned to its original position. When pulled by a preset force, the locking projection (131c) inserted into the locking insertion groove comes out of the locking groove and can be separated from the housing coupling part (141a).

[0130] It should be noted that the housing coupling part (141a) and the coupling projection part (131b) can be implemented in various modified forms of known coupling structures that are coupled to each other when pressed with a preset force and separated from each other when pulled with a preset force, so further detailed description is omitted.

[0131] At the tip of the cleaning handpiece casing part (110), a coupling guide projection (111) is provided, which is positioned spaced apart from the housing coupling part (141a) and supports the outer surface of the coupling projection part (131b).

[0132] The coupling projection (131b) is inserted between the housing coupling portion (141a) and the coupling guide projection (111) so that it can be stably coupled with the housing coupling portion (141a) in the correct position.

[0133] Additionally, on the upper surface of the mounting housing member (131), a rotation support projection (131d) is positioned so as to protrude, which is spaced apart from the outer side of the coupling projection (131b) to support the outer surface of the coupling guide projection (111) when the cleaning skin contact part (130) rotates, and whose upper side is supported by the tip of the cleaning handpiece casing part (110).

[0134] In addition, a bearing ball body (131e) is rotatably inserted inside the rotational support projection (131d), with a portion protruding upward and supported at the tip of the cleaning handpiece casing (110).

[0135] The rotational support projection (131d) is supported by a bearing ball body (131e) at the tip of the cleaning handpiece casing (110) to minimize vibration and movement of the cleaning skin contact part (130) when the cleaning skin contact part (130) rotates, and to allow the cleaning skin contact part (130) to rotate smoothly by the cleaning rotation part (140) while in contact with the skin.

[0136] In order to increase cleaning efficiency during the procedure, when the cleaning handpiece casing (110) is held and pressed to apply pressure to the cleaning skin contact part (130), the cleaning skin contact part (130) is supported by a ball body through a rotation support projection (131d) at the tip of the cleaning handpiece casing (110), so that the pressure is stably transmitted to the cleaning skin contact part (130), and the cleaning skin contact part (130) can be stably rotated by the bearing ball body (131e) even when it is pressed against the skin.

[0137]

[0138] Meanwhile, a cleaning liquid supply line section (150) is located inside the cleaning handpiece casing section (110) to supply cleaning liquid to the cleaning liquid discharge pipe section (120) by connecting the cleaning liquid supply section (not shown) within the control main body section (500), and the cleaning liquid supply line section (150) can be implemented in various forms such as a pipe or a flexible hose.

[0139] Additionally, a foam generating unit (170) that generates foam in the cleaning liquid supplied to the cleaning liquid discharge pipe (120) is provided inside the cleaning handpiece casing (110), and the cleaning liquid supply line (150) includes a first supply line (151) connecting the foam generating unit (170) and the cleaning liquid discharge pipe (120), and a second supply line (152) connecting the cleaning liquid supply unit (not shown) and the foam generating unit (170).

[0140] The foam generating part (170) is provided with a mesh body (171) inside so that foam can be generated as the cleaning liquid passes through the mesh body (171).

[0141] The cleaning liquid discharge pipe (120) discharges and supplies the foam cleaning liquid that has passed through the mesh body (171) to the user's skin, and the cleaning skin contact part (130) rotates by the operation of the cleaning rotating part (140) to evenly apply the foam cleaning liquid to the user's skin.

[0142] One embodiment of the skin cleansing handpiece (100) according to the present invention can further enhance the cleansing effect during cleansing by generating foam in the cleansing solution through the foam generating part (170) and supplying the foam cleansing solution to the user's skin.

[0143] Additionally, inside the cleaning handpiece casing (110), a cleaning liquid suction line (160) is provided by connecting a negative pressure generating part (not shown) that generates negative pressure for suctioning cleaning liquid and a cleaning liquid discharge pipe part (120) to suction cleaning liquid that has been used to clean the skin.

[0144] The cleaning fluid suction line (160) can be implemented in various forms, such as a tube or a flexible hose.

[0145] The cleaning handpiece casing (110) is equipped with an operating switch (180) that controls the operation of a cleaning rotating part (140), a cleaning fluid supply part (not shown), and a negative pressure generating part (not shown), and the operating switch (180) is connected to a control main body (500) through a substrate and a control wire connected to the substrate.

[0274] The handpiece casing (320) for hot and cold massage is equipped with a handle (322b) that the operator can hold with their hand, and a Peltier element (310) is mounted such that one side of the Peltier element (310) is exposed.

[0275] The Peltier element part (310) is positioned so as to be exposed on the outer surface of the handpiece casing part (320) for hot and cold massage, and the outer surface that contacts the skin is formed as an absorbing surface or a dissipating surface so as to be able to cool or heat the user's skin.

[0276] Additionally, the Peltier element section (310) is electrically connected to the hot and cold treatment control section (330) to control its operation, and the hot and cold treatment control section (330) is positioned within the control main body section (500) which is connected to the hot and cold massage handpiece casing section (320) via a control cable.

[0277] It should be noted that the Peltier element (310) is a known thermoelectric element in which the ends of two different conductors are joined and then a DC voltage is applied to the circuit, so one side becomes a heat-absorbing surface and the other side becomes a heat-dissipating surface that dissipates the heat absorbed from the heat-absorbing surface, and further detailed explanation is omitted.

[0278] The hot and cold treatment control unit (330) can change the direction of the current applied to the Peltier element unit (310) to form the outer surface of the Peltier element unit (310) as a heat-absorbing surface to cool the skin, or form the outer surface of the Peltier element unit (310) as a heat-dissipating surface to heat the skin.

[0279] The hot and cold treatment control unit (330) can control the temperature of the heat absorption surface and the temperature of the heat dissipation surface by adjusting the intensity of the current applied to the Peltier element unit (310).

[0280] One embodiment of the handpiece (300) for hot and cold treatment of the skin according to the present invention further includes a temperature sensor part (340) that is mounted on the element mounting surface where the Peltier element part (310) is mounted in the handpiece casing part (320) for hot and cold massage, and contacts the user's skin together with the Peltier element part (310) to detect the user's skin temperature.

[0281] The temperature sensor unit (340) is connected to the hot and cold treatment control unit (330) and transmits the detected temperature information to the hot and cold treatment control unit (330).

[0282] The hot and cold treatment control unit (330) receives real-time skin temperature information detected by the temperature sensor unit (340) during the treatment and controls the operation of the Peltier element unit (310), that is, adjusts the intensity of the current supplied to the Peltier element unit (310) to prevent burns or overcooling of the skin.

[0283] Meanwhile, the handpiece casing part (320) for hot and cold massage includes a massage roller member (321) in which a Peltier element part (310) is positioned to surround the outer surface, and a roller mounting casing member (322) in which the massage roller member (321) is rotatably mounted.

[0285] The Peltier element part (310) is formed in a cylindrical shape and surrounds the outer circumference of the massage roller member (321), so that contact with the skin can be maintained when the massage roller member (321) rotates.

[0286] On the outer surface of the roller shaft (321a), a slip ring portion (323) is provided to supply electric power to the Peltier element portion (310) during the rotation of the massage roller member (321), and on the roller mounting portion (322a), a brush portion (324) is provided to supply electric power to the Peltier element portion (310) during the rotation of the massage roller member (321) by being in contact with the slip ring portion (323) while being elastically supported.

[0287] The brush unit (324) is electrically connected to the hot and cold treatment control unit (330) via a wire, and the slip ring unit is electrically connected to the Peltier element unit (310) via a wire.

[0288] The Peltier element part (310) is electrically connected to the hot and cold treatment control part (330) by the brush part (324) which is elastically in contact with the slip ring part (323) while rotating together with the massage roller part (321), so that operation can be controlled by the hot and cold treatment control part (330).

[0289] The outer diameter of the Peltier element part (310) and the outer diameter of the massage roller member (321) are formed to be the same, and the massage roller member (321) is formed with the same curvature that matches the outer diameter of the Peltier element part (310) on at least one of the two sides of the Peltier element part (310), so that a skin contact part (321b) is provided that can come into contact together when the Peltier element part (310) comes into contact with the skin.

[0290] In addition, the temperature sensor part (340) is mounted on the skin contact part (321b) and positioned so as to be exposed on the outer surface of the skin contact part (321b) so as to be in direct contact with the user's skin and measure the user's skin temperature.

[0291] The temperature sensor unit (340) is provided in multiple units spaced circumferentially around the outer circumference of the skin contact unit (321b), so that when the massage roller member (321) rotates while in contact with the skin, the temperature of the skin can be measured at multiple points to check the change in skin temperature in real time during the procedure.

[0292] Additionally, the skin contact portions (321b) are located on each side of the Peltier element portion (310), and the temperature sensor portion (340) is mounted spaced apart from each of the skin contact portions (321b) on both sides.

[0293] Multiple temperature sensor units (340) are spaced apart along the outer circumference of the skin contact portion (321b) located on both sides of the Peltier element unit (310), so that the skin temperature can be checked on both sides of the Peltier element unit (310) during the procedure.

[0294] The handpiece casing (320) for hot and cold massage is provided with a first display unit (331) and a second display unit (332) for a Peltier element that can respectively display the cooling stage and the heating stage of the Peltier element unit (310), and is provided with a cooling stage control switch unit (333) for controlling the cooling stage of the Peltier element unit (310) and a heating stage control switch unit (334) for controlling the heating stage of the Peltier element unit (310).

[0295] Additionally, the handpiece casing (320) for hot and cold massage is provided with a first temperature display unit (335) for displaying the temperature detected by a plurality of temperature sensor units (340) provided on a skin contact part (321b) on one side, and a second temperature display unit (336) for displaying the temperature detected by a plurality of temperature sensor units (340) provided on a skin contact part (321b) on the other side.

[0296] That is, the hot and cold treatment control unit (330) includes a first display unit (331) for a Peltier element, a second display unit (332) for a Peltier element, a cooling stage control switch unit (333), a heating stage control switch unit (334), a first temperature display display unit (335), and a second temperature display display unit (336).

[0297] For example, the cooling stages of the Peltier element section (310) include cooling stages 1 through 3 in order of increasing temperature of the Peltier element section (310). During the procedure, the operator can control the temperature of the Peltier element section (310) in stages by operating a cooling stage control switch, from cooling stage 1, where the temperature of the Peltier element section (310) is highest, to cooling stage 3, where the temperature of the Peltier element section (310) is lowest.

[0298] For example, the cooling stages of the Peltier element section (310) include cooling stages 1 through 3 in order of increasing temperature of the Peltier element section (310), and the operator can control the temperature of the Peltier element section (310) from the cooling stage 3, where the temperature of the Peltier element section (310) is lowest, to the cooling stage 1, where the temperature of the Peltier element section (310) is highest, by operating the cooling stage control switch section (333) during the procedure.

[0299] Additionally, as an example, the heating stages of the Peltier element section (310) include heating stages 1 through 3 in order of decreasing temperature of the Peltier element section (310), and the operator can control the temperature of the Peltier element section (310) from the lowest temperature of the Peltier element section (310) to the highest temperature of the Peltier element section (310) by operating the heating stage control switch section (334) during the procedure.

[0300] That is, the operator can safely and stably perform the procedure while preventing overheating and overcooling of the skin by selecting a heating stage or a cooling stage of the Peltier element (310) while checking the skin temperature measured on both sides of the massage roller member (321) through the first temperature display display unit (335) and the second temperature display display unit (336).

[0301]

[0302] Meanwhile, one embodiment of the handpiece (300) for hot and cold treatment of the skin according to the present invention further includes an element cooling unit (350) that cools the inner surface of the Peltier element unit (310) inside the massage roller member (321).

[0303] The element cooling unit (350) cools the inner surface of the Peltier element unit (310) inside the massage roller member (321), thereby enabling smooth heat dissipation and heat absorption on the outer surface of the Peltier element unit (310).

[0304] When the outer surface of the Peltier element part (310) operates as a heat absorption surface, the inner surface of the Peltier element part (310) operates as a heat dissipation surface and heat is released. At this time, the element cooling part (350) rapidly cools the heat released to the heat dissipation surface, thereby enabling stable heat absorption operation on the outer surface of the Peltier element part (310).

[0305] Additionally, when the outer surface of the Peltier element part (310) operates as a heat dissipation surface, the inner surface of the Peltier element part (310) operates as a heat absorption surface to absorb heat and cool down. At this time, the element cooling part (350) rapidly cools the heat absorbed by the heat absorption surface, thereby enabling stable heat absorption operation on the outer surface of the Peltier element part (310).

[0306] The interior of the massage roller member (321) is provided with a fluid storage space (321c) filled with a cooling fluid, and the element cooling unit (350) includes a cooling fluid circulation unit (351) that supplies the cooling fluid into the fluid storage space (321c) and discharges and circulates the cooling fluid within the fluid storage space (321c).

[0307] One example of a cooling fluid circulation unit (351) is to circulate cooling air or cooling water within a fluid storage space (321c) to air-cool or water-cool the inner surface of a Peltier element unit (310).

[0308] The fluid supply line section (351a) and the fluid discharge line section (351b) are each detachably connected to the center of the roller shaft (321a) and circulate the cooling fluid within the fluid storage space (321c) through the roller shaft (321a) to maintain the temperature of the cooling fluid within the fluid storage space (321c) at a constant level.

[0309] It should be noted that the cooling fluid circulation unit (351) can be implemented in various modified ways using a known cooling circulation structure that circulates the cooling fluid within the fluid storage space (321c) while maintaining the temperature of the cooling fluid within a preset temperature range, and further detailed explanation is omitted.

[0310] In addition, the inner surface of the Peltier element (310) is positioned so that the entire surface can be exposed to contact with the cooling fluid within the fluid storage space (321c), thereby maximizing the cooling effect by the cooling fluid.

[0311] The cooling fluid circulates within the fluid storage space (321c) inside the massage roller member (321) and cools the inner surface of the Peltier element part (310), thereby enabling the outer surface of the Peltier element part (310) to operate smoothly and stably as a heat dissipation surface and a heat absorption surface.

[0312] In addition, the inner surface of the Peltier element (310) can be stably maintained at a preset temperature by a circulating cooling fluid, so that when the outer surface of the Peltier element (310) is formed as a heat absorption surface or a heat dissipation surface, it can be stably maintained at a constant temperature.

[0313]

[0314] Meanwhile, the handpiece (300) for hot and cold treatment is connected to the control main body (500) and the third control cable body (500c), and the third control cable body (500c) includes a wire for controlling the operation of the Peltier element part (310), a fluid supply line part (351a), and a fluid discharge line part (351b).

[0315] The hot and cold treatment control unit (323) controls the surface temperature of the Peltier element unit (310) in contact with the skin and the operation of the cooling fluid circulation unit (351).

[0316] In addition, the operator can input treatment conditions, such as the temperature of the Peltier element (310) and the treatment time, by directly touching the input section of the main display section (501), which is a touchscreen panel.

[0317] The cold and hot treatment control unit (323) can control the surface temperature of the Peltier element unit (310) in contact with the skin according to the treatment conditions entered by the operator to massage the skin coldly or warmly, and can control the operation of the cooling fluid circulation unit (351) during the treatment to maintain the surface temperature of the Peltier element unit (310) in contact with the skin at a constant set temperature.

[0318] One embodiment of the handpiece (300) for hot and cold treatment of the skin can maintain skin elasticity and prevent aging by heating the skin to an appropriate temperature with a Peltier element and then cooling it, and can soothe the skin by constricting blood vessels and pores by performing a hot and cold massage on the skin before cleansing and applying cosmetics, thereby greatly improving the skin cleansing and the penetration effect of cosmetics.

[0319] In addition, one embodiment of the handpiece (300) for hot and cold treatment of the skin applies a Peltier element to a rotating massage roller so that heating and cooling can be repeated while massaging the skin with the massage roller, thereby greatly increasing the hot and cold massage effect through physical massage.

[0320] The skin beauty device according to the present invention includes a skin cleansing function, a hot and cold massage function, and a cosmetic spraying function, allowing for comprehensive skin care, thereby enabling efficient and convenient skin care.

[0321] The skin beauty device according to the present invention can control the flow of air supplied to or sucked into a plurality of handpieces with a single air compressor, thereby simplifying the structure of the control main body (500) and reducing manufacturing costs.

[0322]

[0323] The present invention can automatically supply foaming cleansing liquid and rotate the skin contact part (130) for cleansing to massage the skin while cleansing, thereby improving the cleansing effect on the skin and increasing convenience during cleansing.

[0324] The present invention can significantly improve convenience during skin cleansing by absorbing the used foam cleansing solution from the skin and removing it along with the cleansed waste.
