[0043] Meanwhile, the discharge head connection terminal (315) is electrically connected to the beauty solution discharge control unit (105), and more specifically, is electrically connected to the control unit connection terminal (803) to receive current from the beauty solution discharge control unit (105).

[0044] Next, the cover portion (303) is coupled to the base portion (301) at the edge, and the cover portion (303) is coupled to the edge of the base body (313) of the base portion (301) to form a coupling space (601) in which the substrate portion (305) is placed.

[0045] To explain the cover portion (303) in more detail, the cover portion (303) has a discharge port coupling hole (317) formed in the center through which the discharge port (C1) of the beauty solution cartridge (C) passes, and an electrode portion coupling hole (319) formed at a certain distance from the discharge port coupling hole (317) to which a plurality of electrode portions (307) are coupled.

[0046] Here, the plurality of electrode coupling holes (319) include a first coupling hole (607) into which the first electrode (603) is inserted with a third length (d3), and a second coupling hole (609) into which the second electrode (605) is inserted with a fourth length (d4).

[0047] Next, the substrate portion (303) is provided in the coupling space (601) and is electrically connected to the base portion (301).

[0048] To explain the structure of the substrate part (303) in more detail, the substrate part (303) includes: a substrate body (321) provided in a coupling space (601) and electrically connected to a base part (301); and an elastic support terminal (323) coupled to the substrate body (321) and electrically connected to the electrode part (307) while elastically supporting the electrode part (307) from the substrate body (321).

[0049] The substrate body (321) is provided in the coupling space (601), supported by the base body (313), and connected to the discharge head connection terminal (315) so as to be electrically connected to the base part (301).

[0050] The substrate body (321) has a coupling projection insertion hole (325) into which a coupling projection (306) is inserted.

[0051] When the coupling projection (306) is inserted into the coupling projection insertion hole (325) of the substrate body (321), the fitting projection (310) is supported on the inner circumference of the coupling projection insertion hole (325), thereby allowing the substrate body (321) to be firmly coupled to the base part (301).

[0052] Next, the elastic support terminal (323) is coupled to the substrate body (321) and electrically connected to the substrate body (313).

[0053] Additionally, the elastic support terminal (323) elastically supports the electrode portion (307) from the substrate body (321) and is electrically connected to the electrode portion (307).

[0054] To specifically describe the structure of the elastic support terminal (323), the elastic support terminal (323) comprises: a terminal body (327) that is coupled to and supported by the substrate body (321); and an elastic support part (329) that is bent and extended from the terminal body (327) and elastically supports the electrode part (307) from the terminal body (327).

[0055] Here, the elastic support member (329) is bent and extended from the end of the terminal body (327) so that when the electrode member (307) is supported, it can be elastically deformed relative to the terminal body (327).

[0056] This elastic support member (329) includes an extension member (331) that extends upward from the terminal body (327) and a support terminal projection (333) that protrudes from the end of the extension member (331) and supports the electrode member (3007).

[0057] Meanwhile, the invention further includes a spring connection terminal (335) disposed in a coupling space (601) according to an embodiment of the present invention, wherein one side is supported by a substrate portion (305) and the other side is supported by an electrode portion (307), elastically supporting the electrode portion (307) from the substrate portion (305) while electrically connecting the substrate portion (305) and the electrode portion (307).

[0058] One side of the spring connection terminal (335) is supported by the elastic support terminal (323) of the substrate (305), and the other side is supported by the electrode (307), so that the electrode (307) is elastically supported from the elastic support terminal (323) and the elastic support terminal (323) and the electrode (307) can be electrically connected.

[0059] As shown in the illustration, this spring connection terminal part (335) may be made of a coil spring, and the other end may be connected to the outside of the support terminal projection (333) so as to be stably supported from the elastic support terminal (323).

[0060] As such, one embodiment of the present invention includes an elastic support terminal (323) and a spring connection terminal part (335), so that the electrode part (307) can be stably supported from the substrate part (305) even when an external force is applied while the electrode part (307) is in close contact with the skin.

[0061] Continuing, the electrode portion (307) is in close contact with the skin and supplies microcurrent to the skin.

[0062] The electrode portion (307) may be provided in multiple numbers.

[0063] One side of the electrode portion (307) is electrically connected to the substrate portion (305), and the other side protrudes outward from the cover portion (303) to supply microcurrent to the skin.

[0064] One side of the electrode portion (307) protruding outward from the cover portion (303) is in close contact with the skin, and the other side is supported by an elastic support terminal (323) or a spring connection terminal portion (335), so that it can receive current from the substrate portion (305) and output a microcurrent.

[0065] Meanwhile, the lengths of the multiple electrode portions (307) protruding from the cover portion (303) may differ so that they can be closely attached to the entire curved skin to supply microcurrent.

[0066] More specifically, the electrode portion (307) may include a first electrode (603) protruding from the cover portion (303) by a first length (d1); and a second electrode (605) spaced apart from the first electrode (603) by a certain distance and protruding from the cover portion (303) by a second length (d2) different from the first length (d1).

[0067] The first electrode (601) can be coupled to the first coupling hole (607) and the second electrode (605) can be coupled to the second coupling hole (609) so that the lengths protruding from the cover portion (303) are different from each other.

[0068] As such, one embodiment of the present invention has improved skin adhesion efficiency, allowing microcurrent to be supplied to the entire curved skin.

[0069] Meanwhile, the beauty solution dispensing head (103) according to one embodiment of the present invention may further include a cartridge detection sensor (201) that outputs cartridge coupling information (i1) when a beauty solution cartridge (C) is coupled to the base part (301).

[0070] The cartridge detection sensor (201) outputs cartridge coupling information (i1) and transmits it to the control unit (203) when the cosmetic solution cartridge (C) is coupled to the base unit (301).

[0071] To explain the structure of the cartridge detection sensor (201) in more detail, the cartridge detection sensor (201) includes: a sensor body (401) coupled to a substrate part (305); and a sensor switch (403) coupled to the sensor body (401) and protruding outward from the base part (301), which outputs cartridge coupling information (i1) while in close contact with the beauty solution cartridge (C) when the base part (301) is coupled to the beauty solution dispensing control unit (105).

[0072] The sensor body (401) is coupled to and fixed to the substrate body (321) of the substrate part (305).

[0073] The sensor switch (403) can be rotatably or movably coupled to the sensor body (401).

[0074] These sensor switches (403) protrude to the outside of the sensor body (401).

[0075] That is, when the substrate part (305) and the cover part (303) are combined, the sensor switch (403) can be penetrated through the switch coupling hole (405) formed in the substrate body (321) and protrude to the outside of the substrate part (305).

[0076] Accordingly, when the cartridge detection sensor (201) is coupled with the beauty solution dispensing control unit (105) to the base part (301), the sensor switch (403) is in close contact with the beauty solution cartridge (C) and moves or rotates from the sensor body (401) to output cartridge coupling information (i1) and transmit it to the control part (203).

[0077] Meanwhile, FIG. 7 is a cross-sectional view of a beauty solution dispensing head (103a) according to another embodiment of the present invention.

[0078] A beauty solution dispensing head (103a) according to another embodiment of the present invention has the same configuration as a beauty solution dispensing head (103) according to one embodiment of the present invention, and each configuration also has the same structure and function.

[0079] However, unlike the first embodiment of the present invention, the beauty solution dispensing head (103a) according to another embodiment of the present invention has the electrode portion (307') electrically connected to the substrate portion (305') through the pogo pin portion (701).

[0081] The cover portion (303') has an electrode portion coupling groove (702) formed to which the electrode portion (307') is coupled, and a pogo pin through hole (705) formed through the electrode portion coupling groove (702) through which the pogo pin portion (701) passes.

[0082] The electrode portion (307') has a recessed pogo pin insertion groove (703) into which the pogo pin portion (701) is inserted.

[0083] One side of the pogo pin portion (701) is penetrated through the pogo pin through hole (705) and supported on the substrate portion (305'), and the other side is coupled to the pogo pin insertion hole (703) to electrically connect the electrode portion (307') and the substrate portion (305').

[0084] Thus, the beauty solution dispensing head (103a) according to another embodiment of the present invention can be used by replacing only the damaged electrode part (307'), thereby reducing maintenance costs.

[0085] As described above, according to one embodiment of the present invention, even when the electrode part (307) is in close contact with the skin and an external force is applied, the electrode part (307) can be stably supported from the substrate part (305), and even when the electrode part (307) and the substrate part (305) are separated by a certain distance, the substrate part (305) and the electrode part (307) can be electrically contacted by the spring connection terminal part (335), and even when the nozzle is clogged by the beauty solution or the beauty solution is contaminated during long-term use, the beauty solution cartridge (C) can be easily replaced.

[0087] Meanwhile, referring to FIGS. 8 to 10, a beauty solution dispensing control unit (105) according to an embodiment of the present invention relates to a beauty solution dispensing control unit (105) coupled to a beauty solution dispensing head (103) to which a beauty solution cartridge (C) is coupled to dispense a beauty solution, comprising: a guide part (801) to which a beauty solution dispensing head (103) is coupled to the front and a beauty solution cartridge (C) is provided on the inside; a driving part (805) disposed at the rear of the guide part (801); and a pressure dispensing part (807) coupled to the driving shaft (821) of the driving part (805) and movably coupled to the inside of the guide part (801), and which pressurizes the beauty solution cartridge (C) so that the beauty solution is dispensed by moving as the driving shaft (821) rotates. It includes a limit sensor unit (809) positioned at the front and rear of the pressurized discharge unit (807) and in contact with the pressurized discharge unit (807) to output a movement detection signal; and a control unit (203) that controls the driving unit (805) by outputting a control signal to limit the movement range of the pressurized discharge unit (807) when the movement detection signal is applied.

[0088] Hereinafter, each configuration of the beauty solution dispensing control unit (105) according to one embodiment of the present invention will be described in detail.

[0100] Next, the drive unit (805) is positioned on the rear side of the guide unit (801).

[0101] The driving unit (805) includes a driving bracket (819) coupled to the housing (101) at the rear side of the coupling space of the housing (101), and a driving motor (823) coupled to the inner side of the driving bracket (819) and equipped with a driving shaft (821).

[0103] Next, the pressure discharge unit (807) pressurizes the beauty solution cartridge (C) so that the beauty solution is discharged while moving inside the guide unit (801) by the driving unit (805).

[0104] Additionally, the pressure discharge unit (807) comes into contact with the limit sensor unit (809) when moving inside the guide unit (801).

[0105] To explain the structure of the pressure discharge unit (807) in more detail, the pressure discharge unit (807) comprises: a movable body (827) that is movably coupled to the inside of the guide unit (801), has a shaft guide hole (825) into which a drive shaft (821) is inserted, and has a sensor pressure projection (826) formed on one side that contacts a limit sensor unit (809); a gear member (829) that is inserted into the inside of the shaft guide hole (825), is coupled to the outside of the drive shaft (821), and moves along the drive shaft (821) when the drive shaft (821) rotates; and a pressure member (831) that is coupled to the front side of the movable body (827) and pressurizes a beauty solution cartridge (C) so that the beauty solution is discharged when the drive shaft (821) rotates in one direction and the movable body (827) moves.

[0106] The movable body (827) is movably coupled to the guide hole (901) of the guide part (801).

[0107] The movable body (827) is movably coupled to a guide projection (903) on one or both sides, and a discharge guide groove (833) is formed that is guided by the guide projection (903).

[0108] Next, the gear member (829) is inserted into the inside of the shaft guide hole (825) and fixed.

[0109] Additionally, the gear member (829) is movably inserted on the outside of the drive shaft (821).

[0110] That is, the gear member (829) moves along the drive shaft (821) together with the pressure discharge part (807) when the drive shaft (821) rotates, and at this time, the pressure discharge part (807) moves inside the guide hole (901).

[0111] The gear member (829) has a thread (907) formed on its inner surface that engages with the thread formed on the outer surface of the drive shaft (821), and a friction-forming projection (909) is formed on its outer surface so that it does not slip inside the shaft guide hole (825) when the drive shaft (821) rotates.

[0112] Meanwhile, the pressure member (831) is coupled to the front side of the movable body (827).

[0113] The pressurizing member (831) pressurizes the beauty solution cartridge (C) so that the beauty solution is discharged when the drive shaft (821) rotates in one direction and the moving body (827) moves forward.

[0114] Additionally, when the drive shaft (821) is rotated in the other direction and the moving body (827) is moved backward, the pressurizing member (831) can be moved in a direction separated from the beauty solution cartridge (C) together with the moving body (827).

[0115] In this pressure member (831), a pressure protrusion area (835) is formed on one side that is in close contact with the beauty solution cartridge (C), which protrudes gradually toward the center.

[0116] Thus, one embodiment of the present invention can minimize the amount of remaining beauty solution inside the beauty solution cartridge (C) when in use.

[0117] Furthermore, the limit sensor unit (809) according to one embodiment of the present invention is positioned at the front and rear of the pressurized discharge unit (807), and when it comes into contact with the pressurized discharge unit (807), it outputs a movement detection signal to limit the movement range of the pressurized discharge unit (807) and transmits it to the control unit (203).

[0118] The limit sensor unit (809) includes: a first limit sensor (837) which is provided on the front side of the pressurized discharge unit (807) and outputs a first movement detection signal (1s) when the drive shaft (821) rotates in one direction and contacts the pressurized discharge unit (807); and a second limit sensor (839) which is provided on the rear side of the pressurized discharge unit (807) and outputs a second movement detection signal (2s) when the drive shaft (821) rotates in the other direction and contacts the pressurized discharge unit (807).

[0119] Meanwhile, one embodiment of the present invention further includes a control unit connection terminal (803) provided in the guide part (801), which supplies current to the beauty liquid discharge head (103) when the beauty liquid discharge head (103) is coupled to the guide part (801), outputs discharge head coupling information (i2), and transmits it to the control part (203).

[0120] A control unit connection terminal (803) is provided in a guide section (801), and when a beauty liquid discharge head (103) is connected to the guide section (801), it outputs discharge head connection information (i2) to supply current to the beauty liquid discharge head (103) and transmits it to the control section (203).

[0121] Subsequently, the control unit (203) controls the drive motor (823) by outputting a control signal to limit the movement range of the pressurized discharge unit (807) when a movement detection signal is applied.

[0122] Referring to FIG. 10, the process of controlling the drive motor (823) by the control unit (203) is briefly explained as follows: as shown in FIG. 10(a), when the drive shaft (821) is rotated in one direction by the drive motor (823) and the pressure discharge unit (807) moves forward while pressurizing the cosmetic liquid cartridge (C), the first limit sensor (837) comes into contact with the sensor pressure projection (826) and outputs a first movement detection signal (1s) and transmits it to the control unit (203), and the control unit (203) outputs a first movement control signal (3s) to control the drive motor (823). At this time, the one-way rotation of the drive shaft (821) is stopped and the forward movement of the pressure discharge unit (807) is stopped.

[0123] At this time, a preset amount of beauty solution is dispensed.

[0124] And, as illustrated in FIG. 10(b), when the drive shaft (821) is rotated in the opposite direction by the drive motor (823) and the pressure discharge part (807) moves in a direction separated from the cosmetic liquid cartridge (C), the second limit sensor (839) comes into contact with the sensor pressure projection (826) and outputs a second movement detection signal (2s) and transmits it to the control unit (203), and the control unit (203) outputs a second movement control signal (4s) to control the drive motor (823), at which time the rotation of the drive shaft (821) in the opposite direction stops and the rear movement of the pressure discharge part (807) stops.

[0125] As such, one embodiment of the present invention includes a limit sensor unit (809) that contacts a pressure discharge unit (807) and outputs a movement detection signal, and a control unit (203) that controls the movement range of the pressure discharge unit (807), so that the user can discharge and use the beauty solution as much as they want and minimize waste of the beauty solution.

[0126] Meanwhile, when the discharge head coupling information (i2) is applied from the control unit connection terminal (803), the control unit (203) controls the output unit (205) by outputting a first control signal (s5) so that the discharge head coupling information (i2) is output through the output unit (205).

[0127] And, when the discharge head coupling information (i2) is applied from the control unit connection terminal (803), the control unit (203) can control the battery unit (207) by outputting a second control signal (s6) to supply current to the beauty solution discharge head (103).

[0128] Additionally, when cartridge coupling information (i1) is received from the cartridge detection sensor (201), the control unit (203) can control the output unit (205) by outputting a third control signal (s7) so that the cartridge coupling information (i1) is output through the output unit (205).

[0129] As described above, according to one embodiment of the present invention, since the beauty solution can be dispensed and used by the user as much as desired by the limit sensor unit (809), the waste of the beauty solution can be minimized and the phenomenon of the nozzle becoming clogged or contaminated during the dispensing process of the beauty solution can be minimized.

[0130] Although it has been described above that all components constituting an embodiment of the present invention are combined or operate as a single unit, the present invention is not necessarily limited to such an embodiment. That is, within the scope of the purpose of the present invention, all components may be selectively combined in one or more ways to operate.

[0131] The foregoing description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications and variations within the scope of the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are intended to explain, not limit, the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by these embodiments. The scope of protection of the present invention shall be interpreted by the claims below, and all technical concepts within an equivalent scope shall be interpreted as being included within the scope of rights of the present invention.
