Description

[Technical Field]

[0001] The present invention relates to a wireless hair dyeing device using electricity and a dyeing method using the same, and more particularly to a hair dyeing device that can be filled with dyeing agents using a cartridge system and a method of using the same. [Background technology]

[0002] Hair dyeing requires mixing a hair dye and an oxidizer and applying it to the hair. Hair dye and oxidizer are chemicals that require caution as they can have adverse effects on human eyesight and contain toxicity. Since users must go through the tedious process of mixing the hair dye and oxidizer contained in the purchased dye in a container, then spreading it on the hair and applying it, many users choose to use a hair dyeing service at a beauty salon or other similar establishment.

[0003] Conventional hair dyeing devices require users to manually pour the hair dye and oxidizer into a single container and then mix them together. Therefore, conventional hair dyeing devices require users to manually squeeze and pour the hair dye and oxidizer into the container, which is inconvenient.

[0004] In addition, to improve dyeing efficiency, the best color suggested by the dye manufacturer can only be achieved when the ratio of hair dye and oxidant is 1:1. However, conventional hair dyers, which require the user to squeeze the dye with any force and then comb it directly, or to pour it into a single container, are unable to achieve the original color of the dye.

[0005] As a technology related to the present invention, a Korean patent publication discloses a hair dyeing device including a body, a dyeing comb, a dyeing agent supply unit, and a driving unit. The dyeing agent supply unit of this related technology includes a structure in which the hair dye and the oxidizing agent are contained in a case, while the present invention is configured such that the multiple dyeing agents that make up the dyeing agent are stored separately and filled in a cartridge system, which distinguishes the configurations and effects of the two inventions from each other.

[0054] 2 and 3, the components of the hair dyer 100 are depicted.

[0055] The head 110 constituting the hair dyeing device 100 can be configured to include a front cover 111 a and a back cover 111 b as a head cover 111 , and a comb 113 .

[0056] The front cover 111a and the rear cover 111b may be combined with each other to form an internal space. The head cover 111 may be combined with the housing 140 so that the internal space is connected to the mixing chamber 181 in the housing 140. The internal space stores dye before being discharged through the nozzle. A comb 113 is fastened and unclamped to the front cover 111a. Holes 111n corresponding to the nozzles formed in the comb 113 may be formed in the front cover 111a.

[0057] The dye discharged through the hole 111n is discharged to the nozzles 124 formed in the base 114 or the nozzles 121n, 122n, and 123n through the tubes inside the cylindrical comb teeth 120.

[0058] Referring again to FIG. 3, the body 130 may be configured to include a discharge section 150 and a mixing section 180 .

[0059] The discharge unit 150 is connected to the housing and pressurizes the cartridges to discharge the first and second dyeing agents stored in the cartridges into the mixing chamber. The discharge unit 150 also discharges the dyeing agents to the outside through nozzles 124, 121n, 122n, and 123n. Here, the first and second dyeing agents correspond to a hair dye and an oxidizing agent. The nozzles 124, 121n, 122n, and 123n will be described in detail with reference to FIGS. 4 and 5.

[0060] The mixer 180 is coupled to the housing 140 and functions to mix the first and second staining agents to generate a staining agent.

[0061] FIG. 4 is an exemplary diagram of a comb according to one embodiment of the present invention.

[0062] FIG. 5 is an enlarged view of a comb according to one embodiment of the present invention.

[0063] 4 and 5, the comb 113 can be fitted in a cartridge-type manner to be fastened and released to the head cover 111. The comb 113 includes a plate-shaped base 114 fastened to the head cover 111 and a plurality of comb teeth 120 extending from the base 114, and the nozzles 121n, 122n, 123n, and 124 can be configured to be formed on at least one of the base and the comb teeth.

[0064] The comb 113 is releasably fastened to the head cover 111, and the comb teeth (120) can be formed with different numbers and lengths. Therefore, the comb 113 designed as a cartridge type can be configured to be interchangeable according to the length of hair.

[0066] Referring again to FIG. 4, the comb teeth 120 may be formed in a cylindrical shape. For example, the first comb teeth 121 may have first nozzles 121n formed in multiple directions on the curved surface of the cylinder. The number of nozzles 121n included in one comb tooth 120 is preferably one to three. Three first nozzles 121n are depicted in FIG. 4 at intervals of 120°. The first nozzle 121n is disposed in the center of the comb 113, and therefore may be configured to discharge more dye than the second nozzles 122n and third nozzles 123n disposed on the sides.

[0067] The nozzles 121n, 122n, and 123n may be formed to be elongated in the longitudinal direction of the comb teeth 120.

[0068] 4, the second comb teeth 122 and the third comb teeth 123 may be configured such that second nozzles 122n and third nozzles 123n are respectively formed on the curved surface of the cylinder in a direction facing the inside of the base part 114. The dye discharged through the structure of the second nozzles 122n and the third nozzles 123n does not flow to the outside of the comb 113 but flows to the inside.

[0069] Referring again to FIG. 5, there is depicted a first comb tooth 121 having three first nozzles 121n formed at 120° intervals, a second comb tooth 122 having second nozzles 122n facing inward, and a third comb tooth 123 having third nozzles 123n facing inward.

[0072] The body 130 can be configured to include a PCB incorporating a control circuit for controlling the operation of the discharge section and the mixing section; and a user interface equipped with input buttons and an LCD screen for operation control.

[0073] FIG. 6 is an internal exploded view of a hair dyer according to one embodiment of the present invention.

[0074] Referring to FIG. 6, the discharge part 150 and the mixing part 180 corresponding to the inner parts 150+180 constituting the body 130 are illustrated.

[0075] The ejection section 150 can be configured to include a cartridge 151 and a drive section 160 .

[0076] The cartridge 151 may be composed of a first cartridge 152 and a second cartridge 153. The first cartridge 152 has a function of storing a first dyeing agent, and the second cartridge 153 has a function of storing a second dyeing agent. The first cartridge 152 and the second cartridge 153 are made of a flexible material, for example, a rubber or silicone tube, and the inside of the first cartridge 152 is filled with a hair dye, and the inside of the second cartridge 153 is filled with an oxidizer.

[0077] The cartridge 151 may be configured to include a tube and a pressure bottom surface 151a coupled to the bottom surface of the tube. The pressure bottom surface 151a is made of a hard material different from the tube and is a portion that receives pressure.

[0078] The driving unit 160 may be configured to include a power unit 161 and a pressure unit 170. The driving unit 160 has a function of compressing the first cartridge 152 and the second cartridge 153 in the vertical direction to squeeze out the first staining agent and the second staining agent.

[0079] The power unit 161 may be configured to include a first motor assembly 163, a shaft 165, and a power supply unit 166. The power unit 161 has a function of driving the first motor assembly 163 using power supplied from the power supply unit 166 and transmitting the generated rotational force to the pressure unit 170 via the shaft 165.

[0080] The power supply unit 166 may be configured to include a battery 166a (not shown) and a charging terminal 166b. The first motor assembly 163 may be configured to include, in addition to the first motor, a rotating shaft that transmits rotational force and various gears.

[0081] The power unit 161 has a function of generating a rotational force. A shaft 165 is connected to the axis of a motor that constitutes the first motor assembly 163. A power supply unit 166 can supply power to the motor.

[0082] The power supply unit 166 may be configured to include a battery (not shown) and a charging terminal 166b. The battery may be provided in the bottom surface 145 of the housing 140. When the hair dyeing device 100 is not in use, the charging terminal 166b is electrically connected to a connector of a docking station (not shown) to charge the battery.

[0083] FIG. 7 is a distribution diagram of the heat rays according to one embodiment of the present invention.

[0084] 7, the power supply unit 166 may be configured to include a heating wire 135. For example, the hair dyeing device 100 may be configured such that the heating wire 135 is distributed in at least one of the frame 171 on which the first cartridge 152 and the second cartridge 153 are mounted, the mixing chamber 181, and the internal space of the head 110 to increase the temperature of the first dyeing agent, the second dyeing agent, and the mixed dyeing agent, thereby increasing chemical activity. When the temperature of the dyeing agent reaches a certain temperature, e.g., 45°C, using a sensor installed in the mixing chamber 181, the user interface 132 may notify the user through audio and visual signals that dyeing is possible.

[0085] The pressure applying unit 170 can be configured to include a frame 171, a fixed unit 175, and a moving unit 179. The pressure applying unit 170 has a function of applying pressure to the first cartridge 152 and the second cartridge 153 by converting a rotational force into a linear movement.

[0086] The first cartridge 152 and the second cartridge 153 are sold as products fully filled with the first and second staining agents. Alternatively, a user may directly fill the first cartridge 152 with the first staining agent using an auxiliary tool, such as a syringe, and directly fill the second cartridge 153 with the second staining agent. Therefore, two types of cartridges 151 may be provided. One is a finished product in which the staining agent is contained in the cartridge 151 and is sold sealed, and the other is a type in which the cartridge 151 can be filled with general staining agents. In another embodiment of the cartridge 151, a filling cap 151b, as shown in FIG. 6, may be further provided on the pressurized bottom surface 151a coupled to the cartridge 151.

[0087] The frame 171 has a front frame 171a and a rear frame 171b coupled to each other to form a space in which the first cartridge 152 and the second cartridge 153 can be placed. The rear frame 171b can be configured to be detached from the front frame 171a for replacement of the first cartridge 152 and the second cartridge 153. A coupling portion 173 can be formed on the rear frame 171b. The coupling portion 173 can be configured to mate with the inner surface of the rear surface 143 of the housing 140. The rear frame 171b can be configured to be openable and closable when replacing the cartridge 151.

[0088] The fixed part 175 is fixed to one side of the interior of the frame 171, and the moving part 179 is movably disposed on the other side of the interior of the frame 171. The moving part 179 moves along the shaft 165 rotated by the first motor assembly 163.

[0089] When the moving part 179, which moves due to the action of the shaft 165, is fully compressed as the first and second staining agents are discharged from the first and second cartridges 152 and 153, the pressing bottom surface 151a overlaps with the fixing part 175. In this case, the moving part 179 and the pressing bottom surface 151a are manufactured in a hemispherical or conical shape with the same curvature so that the contact surfaces are in complete contact and the staining agents are fully discharged from the first and second cartridges 152 and 153.

[0090] A rail along which the moving part 179 moves may be formed between the front frame 171a and the rear frame 171b. The moving part 179 moves along the rail in a direction that compresses the first cartridge 152 and the second cartridge 153.

[0091] When the motor constituting the first motor assembly 163 rotates and the shaft 165 connected to the motor rotates, the moving part 179 moves forward along the shaft 165, and the moving part 179 presses the lower ends of the first cartridge 152 and the second cartridge 153, thereby discharging the first staining agent and the second staining agent from the first cartridge 152 and the second cartridge 153. The first cartridge 152 and the second cartridge 153 are tubular and made of a flexible material, and the volume of each cartridge decreases due to the pressure of the moving part 179, allowing the first staining agent and the second staining agent to be discharged.

[0092] The mixing section 180 may be configured to include a mixing chamber 181 , a screw 183 and a second motor assembly 185 .

[0093] The mixing chamber 181 has a function of temporarily storing the first staining agent discharged from the first cartridge 152 and the second staining agent discharged from the second cartridge 153.

[0094] The mixing chamber 181 may be formed by combining a front chamber case 181a and a rear chamber case 181b. A screw 183 and a second motor assembly 185 are disposed within the mixing chamber 181. The screw 183 is rotated by receiving rotational force from the second motor assembly 185. The rotation of the screw 183 causes the first dyeing agent and the second dyeing agent to mix with each other, thereby producing a dye. The second motor assembly 185 may be configured to include a second motor, a rotating shaft for transmitting rotational force, and various gears.

[0095] In addition to the first cartridge 152 and the second cartridge 153, cleaning cartridges may also be provided. The two cleaning cartridges, which are the same size as the first cartridge 152 and the second cartridge 153, may contain a cleaning substance, for example, a liquid containing alcohol. By installing the cleaning cartridges in the hair dyeing device 100 instead of the first cartridge 152 and the second cartridge 153 and operating the hair dyeing device 100 in the same manner as during dyeing, the dyeing agent components stuck to the mixing chamber 181, internal space, and pipes of the hair dyeing device 100 are dissolved and discharged.

[0096] FIG. 8 is a flowchart of a dyeing method using a hair dyer according to one embodiment of the present invention.

Alternatively, the user may directly fill the first cartridge 152 with the first staining agent using, for example, a syringe-shaped auxiliary tool, and directly fill the second cartridge 153 with the second staining agent.

[0100] Next, the user can attach the first cartridge 152 and the second cartridge 153 to the internal housing, i.e., the frame 171, of the hair dyeing device 100 (step S120). To replace the first cartridge 152 and the second cartridge 153, the cap 144 of the housing 140 and the rear frame 171b or the bottom surface 145 of the housing 140 can be configured to be opened and closed.

[0101] Next, the user can operate the hair dyeing device 100 to discharge the first and second dyeing agents into the mixing chamber 181 inside the hair dyeing device 100 (step S130). The user can operate the hair dyeing device 100 through the user interface 132. That is, when the power of the hair dyeing device 100 is turned on, the power unit 161 operates, and the pressure unit 170 pressurizes the first cartridge 152 and the second cartridge 153, and the first and second dyeing agents begin to be discharged into the mixing chamber 181 through the second cartridge 153 and the cartridge nozzle 154 of the second cartridge 153 shown in FIG.

[0102] The user interface 132 can be configured to include various input buttons and an LCD screen. The input buttons allow the user to operate the menus required for operation. The LCD screen has the function of displaying the operating status of the hair dyeing device 100.

[0103] When the hair dyeing device 100 is turned on, the temperature of the first dyeing agent, the second dyeing agent, or the dyeing agent is increased by the heating wires 135 distributed in at least one of the frame 171, the mixing chamber 181, and the internal space of the head 110. The heating by the heating wires 135 increases the activity of the first dyeing agent, the second dyeing agent, or the dyeing agent, so that the dyeing reaction can occur actively.

[0104] The hair dyeing device 100 may include a control circuit 131 in the form of a PCB, which controls the power unit 161 to drive the hair dyeing device 100. The control circuit may include circuits required for charging and discharging the battery, driver circuits for driving the first motor assembly 163 and the second motor assembly 185, etc.

[0105] The relative sizes of the first cartridge 152 and the second cartridge 153 may be determined by the mixing ratio of the first staining agent and the second staining agent. For example, if the mixing ratio of the first staining agent and the second staining agent is the same (1:1), the first cartridge 152 and the second cartridge 153 may be configured to have the same volume. Otherwise, the volume and thickness of the first cartridge 152 and the second cartridge 153 are determined by the mixing ratio.

[0106] Next, the user can drive the hair dyeing device 100 to mix the dyeing agents in the mixing chamber (step S140). When the hair dyeing device 100 is driven and the first and second dyeing agents are discharged into the mixing chamber 181, the hair dyeing device 100 operates the second motor assembly 185 to start mixing the first and second dyeing agents to produce a dye.

[0107] Finally, the user can operate the hair dyeing device 100 to discharge the dye produced through mixing to the outside of the hair dyeing device (step S150). When the mixing chamber 181 is filled with the mixed dye by discharging and mixing the first and second dyeing agents, the dye moves into the internal space of the head 110 through the chamber nozzle 182 depicted in FIG. 6. When the internal space of the head 110 is filled with the dye, the dye moves along the tube inside the comb tines 120 and is discharged through the nozzle 124 formed on the base 114 and the nozzles 121n, 122n, and 123n formed on the comb tines 120. In addition, the user can adjust the dye discharge speed, etc., through the user interface 132.

[0108] Thus, according to one embodiment of the present invention, one problem to be solved by the present invention is to provide a hair dyeing device that can instantly mix and use dyeing agents that make up a dyeing agent.

[0109] SUMMARY OF THE INVENTION One problem to be solved by the present invention is to provide a hair dyeing device that can be filled with dyeing agents using a cartridge system without injecting dyeing agents.
