Description

TECHNICAL FIELD

The present invention relates to a wireless hair-coloring device using electricity and a coloring method using the same, and more particularly, to a hair-coloring device that can be loaded with dyeing agents in a cartridge and a method of using the same.

BACKGROUND ART

To perform hair coloring, it is necessary to mix a hair colorant and an oxidizing agent and apply the mixture to the hair. The hair colorant and oxidizing agent are chemical substances that may adversely affect human vision and may contain toxicity, thus requiring caution. Since users must go through the cumbersome task of mixing the hair colorant and oxidizing agent provided in a purchased hair-coloring product and applying the mixture to the hair, they often rely on coloring services at hair salons.

A hair-coloring device according to a related art has a configuration in which a hair colorant and an oxidizing agent are manually introduced into a single container and then used after mixing. Accordingly, the hair-coloring device according to the related art has the inconvenience that the user has to manually squeeze and inject the hair colorant and oxidizing agent.

In addition, in order to increase the efficiency of dyeing, the ratio of the hair colorant to the oxidizing agent must be an equal amount of 1:1 to achieve the optimal color intended by the manufacturer of the hair-coloring agent, but in reality, conventional hair-coloring devices, in which the user squeezes and mixes the agents manually with arbitrary force and applies them using a comb, or injects them into a single container, make it difficult to achieve the intended color of the coloring agent.

As a technology related to the present invention, a Korean registered patent publication discloses a hair-coloring device including a body part, a coloring comb, a dye solution supply part, and a drive part. The dye solution supply part in this related art includes a configuration in which the hair colorant and oxidizing agent are stored together in a single-space case, whereas the present invention is distinguished from the related art in both configuration and effect in that a plurality of dyeing agents constituting dye are stored separately and loaded in a cartridge manner.

Alternatively, the user may directly fill the first dyeing agent into the first cartridge 152 and the second dyeing agent into the second cartridge 153 using, for example, an auxiliary tool in the form of a syringe. Accordingly, two types of cartridges 151 may be provided. One is in the form of a finished product in which the dyeing agent is prefilled and sealed within the cartridge 151 at the time of sale, and another is in the form that can be filled with a general dyeing agent by the user. According to another embodiment of the cartridge 151, a filling cap 151b as illustrated in FIG. 6 may be further provided on the pressing bottom 151a coupled to the cartridge 151.

The frame 171 may be formed by coupling a front frame 171a and a rear frame 171b, and may define a space in which the first cartridge 152 and the second cartridge 153 can be mounted. The rear frame 171b may be configured to be detachable from the front frame 171a to allow replacement of the first cartridge 152 and the second cartridge 153. A coupling portion 173 may be formed on the rear frame 171b. The coupling portion 173 may be configured to fit into the inner surface of the rear portion 143 of the housing 140. The rear frame 171b may be configured to open and close when the cartridge 151 is replaced.

The fixing part 175 may be fixed to one side of the interior of the frame 171, and the moving part 179 may be movably disposed on the opposite side of the interior of the frame 171. The moving part 179 may move along the shaft 165 rotated by the first motor assembly 163.

When the first dyeing agent and the second dyeing agent are discharged and the first cartridge 152 and the second cartridge 153 are fully compressed, the pressing bottom 151a, driven by the moving part 179 that moves by the action of the shaft 165, comes to overlap with the fixing part 175. In this case, in order to ensure complete discharge of the dyeing agents from the first cartridge 152 and the second cartridge 153, the moving part 179 may be formed in a hemispherical or conical shape with the same curvature of the pressing bottom 151a, so that their contact surfaces come into full close contact with each other.

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

When the motor constituting the first motor assembly 163 rotates and the shaft 165 connected to the motor also rotates, the moving part 179 advances along the shaft 165, and presses the bottom ends of the first cartridge 152 and the second cartridge 153, so that the first dyeing agent and the second dyeing agent can be discharged from the first cartridge 152 and the second cartridge 153. The first cartridge 152 and the second cartridge 153 are formed in the shape of tubes made of a flexible material, so that the first dyeing agent and the second dyeing agent can be discharged as the volumes are reduced under the pressure of the moving part 179.

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

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

The mixing chamber 181 may be configured by coupling a front chamber case 181a and a rear chamber case 181b. The screw 183 and the second motor assembly 185 may be arranged within the mixing chamber 181. The screw 183 may rotate by receiving rotational force from the second motor assembly 185. By the rotation of the screw 183, the first dyeing agent and the second dyeing agent may be mixed to generate hair dye. The second motor assembly 185 may be configured to include, in addition to a second motor, a rotating shaft and various gears for transmitting rotational force.

In addition to the first cartridge 152 and the second cartridge 153, cleaning cartridges may further be provided. Two cleaning cartridges having the same size as the first cartridge 152 and the second cartridge 153 may contain a substance used for cleaning, such as a liquid including an alcohol component. By mounting the cleaning cartridges in the hair-coloring device 100 in place of the first cartridge 152 and the second cartridge 153 and operating the hair-coloring device 100 in the same manner as during dyeing, the hair dye components that remain adhered to the mixing chamber 181, internal space, and channels of the hair-coloring device 100 may be dissolved and discharged.

That is, when the power of the hair-coloring device 100 is turned on, the power unit 161 operates, and the pressing unit 170 presses the first cartridge 152 and the second cartridge 153, whereby the first dyeing agent and the second dyeing agent begin to be discharged into the mixing chamber 181 through the cartridge nozzles 154 of the first cartridge 152 and the second cartridge 153, as illustrated in FIG. 6.

The user interface 132 may be configured to include various input buttons and an LCD screen. The user may operate menus necessary for driving the device using the input buttons. The LCD screen has a function of displaying the operational status of the hair-coloring device 100.

When the power of the hair-coloring device 100 is turned on, the temperature of the first dyeing agent, the second dyeing agent, or the hair dye may be increased by the heating wire 135 distributed in at least one of the frame 171, the mixing chamber 181, or the internal space of the head 110. Through the heating of the heating wire 135, the activity of the first dyeing agent, the second dyeing agent, or the hair dye may be enhanced, thereby promoting the dyeing reaction.

The hair-coloring device 100 may include a control circuit 131 in the form of a PCB, and the control circuit may drive the hair-coloring device 100 by controlling the power unit 161. The control circuit may include a circuit for charging and discharging the battery, a driver circuit for driving the first motor assembly 163 and the second motor assembly 185, and the like.

The relative sizes of the first cartridge 152 and the second cartridge 153 may be determined according to the mixing ratio of the first dyeing agent and the second dyeing agent. For example, if the mixing ratio of the first dyeing agent and the second dyeing agent is 1:1, the first cartridge 152 and the second cartridge 153 may be configured with the same volume. Otherwise, the volume and thickness of the first cartridge 152 and the second cartridge 153 may be determined according to the mixing ratio.

Next, the user may operate the hair-coloring device 100 to mix the dyeing agents within the mixing chamber (S140). When the hair-coloring device 100 is operated and the first dyeing agent and the second dyeing agent are discharged into the mixing chamber 181, the hair-coloring device 100 begins to operate the second motor assembly 185 to mix the first dyeing agent with the second dyeing agent, thereby starting to generate hair dye.

Finally, the user may operate the hair-coloring device 100 to discharge the hair dye generated through mixing to the outside of the hair-coloring device (S150). When the mixing chamber 181 is filled with the mixed hair dye as a result of the discharge and mixing of the first dyeing agent and the second dyeing agent, the hair dye moves into the internal space of the head 110 through the chamber nozzle 182 illustrated in FIG. 6. When the internal space of the head 110 is filled with the hair dye, the hair dye may move along the internal passage of the comb teeth 120 and be discharged through the nozzle 124 formed in the comb base 114 and the nozzles 121n, 122n, and 123n formed in the comb teeth 120. In addition, the user may control the discharge rate of the hair dye through the user interface 132.
