Description

Technical Field

[0001] The present invention relates to a wireless hair dyeing device using electricity and a dyeing method using the device, and more particularly to a hair dyeing device capable of loading a dyeing agent in a cartridge and a method of using the device. Background Art

[0002] In order to dye hair, it is necessary to mix a hair dyeing colorant and an oxidizing agent and apply the mixture to the hair. The hair dyeing colorant and the oxidizing agent are chemical substances that may have an adverse effect on human vision and may contain toxicity, so they need to be used with caution. Since users have to go through the cumbersome task of mixing the hair dyeing colorant and the oxidizing agent provided in the purchased hair dyeing product and applying the mixture to the hair, they often rely on hair dyeing services at beauty salons.

[0003] According to the related art, a hair dyeing device has the following configuration: manually introducing a hair dyeing colorant and an oxidizing agent into a single container and then using it after mixing. Therefore, the hair dyeing device according to the related art has the inconvenience that the user has to manually squeeze and inject the hair dyeing colorant and the oxidizing agent.

[0004] In addition, in order to improve the efficiency of dyeing, the ratio of the hair dyeing colorant to the oxidizing agent must be an equal amount of 1:1 to achieve the best color expected by the hair dye manufacturer. However, in practice, conventional hair dyeing devices (where the user manually squeezes and mixes these reagents with any force, applies them with a comb, or injects them into a single container) make it difficult to achieve the expected color of the dyeing agent.

[0005] As a technology related to the present invention, a Korean registered patent publication discloses a hair dyeing device including a main body portion, a dyeing comb, a dye solution supply portion, and a driving portion. The dye solution supply portion of the related art includes a configuration in which a hair dyeing colorant and an oxidizing agent are stored together in a single space housing, but the present invention is different from the related art in terms of configuration and effect, and is characterized in that a plurality of dyeing agents constituting the dye are separately stored and loaded in a cartridge form. Summary of the Invention

[0052] Hereinafter, embodiments of the present invention will be described in detail with reference to the relevant drawings.

[0053] On the XYZ coordinate axes indicated in the figure, respectively, the X-axis direction is defined as the width direction of the hair dyeing device 100, the Z-axis direction is defined as the length direction of the hair dyeing device 100, and the Y-axis direction is defined as the thickness direction of the hair dyeing device 100.

[0054] Figure 1 is an exemplary view of a hair dyeing device according to an embodiment of the present invention.

[0055] Referring to Figure 1 , the hair dyeing device 100 according to an embodiment of the present invention may be configured to include a head 110 and a main body 130.

[0056] The main body 130 including the head 110 may be formed in a shape that is symmetric about the Z-axis. The head 110 may be formed in a shape that becomes narrower toward the tip of the head 110, such as a curved triangular shape, so that a larger amount of hair dye can be stored at the portion connected to the main body 130 at the X-axis coordinate compared to the tip of the head 110.

[0057] When viewed from the Y-axis coordinate, the head 110 may be formed in a curved shape that curves from the back to the front compared to the portion of the head 110 connected to the main body 130, and the thickness gradually decreases toward the tip of the head 110.

[0058] Generally, the head 110 may include an internal space and may be formed in a pointed shape, and the appearance of the pointed shape looks blunt at the tip of the head 110 and is flat in the thickness (Y-axis) direction.

[0059] The head 110 may be connected to the main body 130. Specifically, the head 110 may be detachably connected to the main body 130, for example, by fitting engagement. The head 110 may include a nozzle through which the hair dye is discharged. Specifically, the head 110 may include a comb 113, and the nozzle may be formed in the comb 113. In other words, the nozzle may be formed to pass through the inside and outside of the comb 113. In addition, the nozzle fastened to the head 110 may be configured to communicate with the inside of the main body 130 via the internal space of the head 110.

[0065] The head 110 constituting the hair - dyeing device 100 can be configured to include a head cover 111, and the head cover includes a front cover 111a, a rear cover 111b, and a comb 113.

[0066] The front cover 111a and the rear cover 111b can be joined together to form an internal space. The head cover 111 can be coupled to the housing 140 such that the internal space is connected to a mixing chamber 181 inside the housing 140. Before the hair dye is discharged through the nozzle, the internal space can store the hair dye. The comb 113 can be fastened to the front cover 111a and detached from the front cover 111a. A hole 111n corresponding to the nozzle formed in the comb 113 can be formed in the front cover 111a.

[0067] The hair dye discharged through the hole 111n is discharged to the nozzles 121n, 122n, and 123n through the nozzle 124 formed in the comb base 114 or through the internal channels of the cylindrical comb teeth 120.

[0068] Referring again to Figure 3 , the body 130 can be configured to include a discharge part 150 and a mixing part 180.

[0069] The discharge part 150 is coupled to the housing and is used to press a plurality of cartridges so as to discharge the first coloring agent and the second coloring agent stored in the cartridges inside to the mixing chamber. The discharge part 150 is also used to discharge the hair dye to the outside through the nozzles 124, 121n, 122n, and 123n. Here, the first coloring agent and the second coloring agent can respectively correspond to the hair - dyeing colorant and the oxidant. Referring toFigure 4 and Figure 5 describe the nozzles 124, 121n, 122n and 123n in more detail.

[0070] The mixing section 180 is coupled to the housing 140 and is configured to mix a first coloring agent and a second coloring agent to produce a hair dye.

[0071] Figure 4 is an exemplary view of a comb according to an embodiment of the present invention.

[0072] Figure 5 is an enlarged view of a comb according to an embodiment of the present invention.

[0073] Referring to Figure 4 and Figure 5 , the comb 113 may be a cartridge type and may be fastened to the head cover 111 and detached from the head cover 111 via a mating engagement. The comb 113 may include a plate-like comb base 114 fastened to the head cover 111, and a plurality of comb teeth 120 extending from the comb base 114. The nozzles 121n, 122n, 123n and 124 may be formed in at least one of the comb base 114 or the comb teeth 120.

[0074] The comb 113 may be detachably fastened to the head cover 111, and the plurality of comb teeth 120 may be configured to have different lengths. Accordingly, the comb 113 of a replaceable cartridge type may be replaced according to the length of the hair.

[0076] Referring again to Figure 4 , the comb teeth 120 may be formed in a cylindrical shape. Additionally, for example, a plurality of first nozzles 121n may be formed in a plurality of directions on the curved surface of the cylinder of the first comb teeth 121. The number of the nozzles 121n included in one comb tooth 120 is preferably 1 to 3. Figure 4 Three first nozzles 121n arranged at intervals of 120 degrees are shown in

[0077] The nozzles 121n, 122n and 123n may be formed in an elongated shape along the length direction of the comb teeth 120.

[0078] Referring again to Figure 4, the second comb tooth 122 and the third comb tooth 123 can be configured such that the second nozzle 122n and the third nozzle 123n are respectively formed on the surfaces of each corresponding cylindrical comb tooth in a direction facing the inner side of the comb base 114. Due to the structures of the second nozzle 122n and the third nozzle 123n, the hair dye discharged through them can flow inward from the comb 113 instead of outward.

[0079] Referring again to Figure 5 , a first comb tooth 121 having three first nozzles 121n formed at 120-degree intervals, a second comb tooth 122 having a second nozzle 122n formed in an inward direction, and a third comb tooth 123 having a third nozzle 123n formed in an inward direction are shown.

[0082] The main body 130 can be configured to include: a PCB with a built-in control circuit for controlling the operations of the discharging unit and the mixing unit; and a user interface provided with input buttons and an LCD screen for controlling the operations.

[0083] Figure 6 is an exploded view of the interior of a hair dyeing device according to an embodiment of the present invention.

[0084] Referring to Figure 6 , the discharging unit 150 and the mixing unit 180 corresponding to the inner bodies 150 and 180 constituting the main body 130 are shown.

[0085] The discharging unit 150 can be configured to include a cylinder 151 and a driving unit 160.

[0086] The cartridge 151 may include a first cartridge 152 and a second cartridge 153. The first cartridge 152 has the function of storing a first coloring agent. The second cartridge 153 has the function of storing a second coloring agent. The first cartridge 152 and the second cartridge 153 may be formed as tubes made of a flexible material (such as rubber or silicone), and the interior of the first cartridge 152 may be filled with hair dye, while the interior of the second cartridge 153 may be filled with an oxidant.

[0087] The cartridge 151 may be configured to include a tube and a pressing bottom 151a coupled to the bottom of the tube. The pressing bottom 151a is made of a material harder than the tube and serves as a component for receiving the applied pressure.

[0088] The driving unit 160 may be configured to include a power unit 161 and an extrusion unit 170. The driving unit 160 has the function of vertically pressing the first cartridge 152 and the second cartridge 153 to extrude the first coloring agent and the second coloring agent.

[0089] The power unit 161 may be configured to include a first motor assembly 163, a shaft 165, and a power source 166. The power unit 161 is used to drive the first motor assembly 163 using the power supplied from the power source 166 and transmit the generated rotational force to the pressing unit 170 via the shaft 165.

[0090] The power source 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 a rotating shaft for transmitting the rotational force and various gears in addition to the first motor.

[0091] The power unit 161 has the function of generating a rotational force. The shaft 165 may be connected to the shaft of the motor constituting the first motor assembly 163. The power source 166 may supply power to the motor.

[0092] The power source 166 may be configured to include a battery (not shown) and a charging terminal 166b. The battery may be disposed in the bottom 145 of the housing 140. When the hair dyeing device 100 is not in use, the charging terminal 166b may be electrically connected to a connector of a charging docking station (not shown) so that the battery can be charged.

[0093] Figure 7 is a diagram showing the distribution of heating wires according to an embodiment of the present invention.

[0094] Referring to Figure 7, the power supply 166 can be configured to include a heating wire 135. For example, the hair dyeing device 100 can be configured such that the heating wire 135 is distributed in at least one of the inner spaces of the frame 171 for mounting the first cylinder 152 and the second cylinder 153, the mixing chamber 181, or the head 110 to increase the temperature of the first dye, the second dye, and the mixed hair dye, thereby enhancing their chemical activity. When the temperature of the hair dye reaches a specific temperature (e.g., 45 degrees Celsius) detected by a sensor installed in the mixing chamber 181, the user interface 132 can notify by an audible signal and a visual signal that the device is ready for dyeing.

[0095] The pressing unit 170 can be configured to include a frame 171, a fixing part 175, and a moving part 179. The pressing unit 170 has a function of converting a rotational force into a linear movement to press the first cylinder 152 and the second cylinder 153.

[0096] The first cylinder 152 and the second cylinder 153 can be sold in the form of products pre-filled with the first dye and the second dye. Alternatively, the user can directly fill the first cylinder 152 with the first dye and the second cylinder 153 with the second dye using an auxiliary tool in the form of an injector, for example. Thus, two types of cylinders 151 can be provided. One is in the form of a finished product, where the dye is pre-filled and sealed in the cylinder 151 at the time of sale, and the other form is that the user can fill it with ordinary dye. According to another embodiment of the cylinder 151, as Figure 6 shown, a filling cap 151b can be further provided on the pressing bottom 151a connected to the cylinder 151.

[0097] The frame 171 can be formed by connecting a front frame 171a and a rear frame 171b, and can define a space where the first cylinder 152 and the second cylinder 153 can be installed. The rear frame 171b can be configured to be detachable from the front frame 171a to allow replacement of the first cylinder 152 and the second cylinder 153. A connecting part 173 can be formed on the rear frame 171b. The connecting part 173 can be configured to be assembled into the inner surface of the rear part 143 of the housing 140. The rear frame 171b can be configured to open and close when replacing the cylinder 151.

[0098] The fixing part 175 can be fixed to one side inside the frame 171, and the moving part 179 can be movably arranged on the opposite side inside the frame 171. The moving part 179 can move along the shaft 165 rotated by the first motor assembly 163.

[0099] When the first coloring agent and the second coloring agent are discharged and the first cylinder 152 and the second cylinder 153 are completely compressed, the pressing bottom 151a driven by the moving part 179 that moves under the action of the shaft 165 is stacked with the fixing part 175. In this case, in order to ensure the complete discharge of the coloring agent from the first cylinder 152 and the second cylinder 153, the moving part 179 can be formed into a hemispherical or conical shape having the same curvature as the pressing bottom 151a, so that their contact surfaces are in complete close contact with each other.

[0100] A guide rail can be formed between the front frame 171a and the rear frame 171b, and the moving part 179 can move along the guide rail. The moving part 179 can move along the guide rail in the direction of compressing the first cylinder 152 and the second cylinder 153.

[0101] 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 cylinder 152 and the second cylinder 153, so that the first coloring agent and the second coloring agent can be discharged from the first cylinder 152 and the second cylinder 153. The first cylinder 152 and the second cylinder 153 are formed in the shape of a tube made of a flexible material, so that when the volume decreases under the pressure of the moving part 179, the first coloring agent and the second coloring agent can be discharged.

[0102] The mixing part 180 can be configured to include a mixing chamber 181, a screw 183, and a second motor assembly 185.

[0103] The mixing chamber 181 has the function of temporarily storing the first coloring agent discharged from the first cylinder 152 and the second coloring agent discharged from the second cylinder 153.

[0104] The mixing chamber 181 can be configured by coupling a front chamber housing 181a and a rear chamber housing 181b. The screw 183 and the second motor assembly 185 can be arranged inside the mixing chamber 181. The screw 183 can rotate by receiving the rotational force from the second motor assembly 185. By the rotation of the screw 183, the first coloring agent and the second coloring agent can be mixed to generate a hair dye. The second motor assembly 185 can be configured to include a rotating shaft for transmitting the rotational force and various gears in addition to the second motor.

[0105] In addition to the first cylinder 152 and the second cylinder 153, a cleaning cylinder can be further provided. Two cleaning cylinders having the same size as the first cylinder 152 and the second cylinder 153 can accommodate substances for cleaning, such as a liquid including an alcohol component. By installing the cleaning cylinder in the hair dyeing device 100 in place of the first cylinder 152 and the second cylinder 153 and operating the hair dyeing device 100 in the same manner as during dyeing, the hair dye components adhering to the mixing chamber 181, the internal space, and the channels of the hair dyeing device 100 can be dissolved and discharged.

[0106] Figure 8 is a flowchart showing a method of using a hair dyeing device according to an embodiment of the present invention.

[0107] Referring to Figure 8 , the dyeing method (S100) may include: preparing a first cylinder and a second cylinder (S110); installing the first cylinder and the second cylinder inside the hair dyeing device 100 (S120); discharging a first dyeing agent and a second dyeing agent inside (S130); mixing the first dyeing agent and the second dyeing agent (S140); discharging the hair dye to the outside.

[0108] The user can use the hair dyeing device 100 to perform hair dyeing, in which the cylinders storing the first dyeing agent and the second dyeing agent are replaceable (S100).

[0109] The user can prepare a first cylinder 152 storing the first dyeing agent and a second cylinder 153 storing the second dyeing agent (S110). The first cylinder 152 and the second cylinder 153 can be sold in the form of products pre-filled with the first dyeing agent and the second dyeing agent. Alternatively, the user can directly fill the first dyeing agent into the first cylinder 152 and the second dyeing agent into the second cylinder 153 using an auxiliary tool such as an injector.

[0110] Next, the user can install the first cylinder 152 and the second cylinder 153 into the inner housing (i.e., the frame 171) of the hair dyeing device 100 (S120). To replace the first cylinder 152 and the second cylinder 153, the lid 144 of the housing 140 and the rear frame 171b or the bottom 145 of the housing 140 can be configured to open and close.

[0111] Next, the user can operate the hair dyeing device 100 to discharge the first dyeing agent and the second dyeing agent into the mixing chamber 181 inside the hair dyeing device 100 (S130). The user can operate the hair dyeing device 100 via the user interface 132. In other words, when the power of the hair dyeing device 100 is turned on, the power unit 161 operates, and the pressing unit 170 presses the first cylinder 152 and the second cylinder 153, whereby the first dyeing agent and the second dyeing agent start to be discharged into the mixing chamber 181 through the cylinder nozzles 154 of the first cylinder 152 and the second cylinder 153, as Figure 6 shown.

[0112] The user interface 132 can be configured to include various input buttons and an LCD screen. The user can use the input buttons to operate the menus required to drive the device. The LCD screen has the function of displaying the operating state of the hair dyeing device 100.

[0113] When the power of the hair dyeing device 100 is turned on, the temperature of the first dye, the second dye, or the hair dye can be increased by the heating wire 135 distributed in at least one of the inner spaces of the frame 171, the mixing chamber 181, or the head 110. By heating with the heating wire 135, the activity of the first dye, the second dye, or the hair dye can be enhanced, thereby promoting the dyeing reaction.

[0114] The hair dyeing device 100 may include a control circuit 131 in the form of a PCB, and the control circuit may drive the hair dyeing 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.

[0115] The relative sizes of the first cylinder 152 and the second cylinder 153 may be determined according to the mixing ratio of the first dye and the second dye. For example, if the mixing ratio of the first dye and the second dye is 1:1, the first cylinder 152 and the second cylinder 153 may be configured to have the same volume. Additionally, the volumes and thicknesses of the first cylinder 152 and the second cylinder 153 may be determined according to the mixing ratio.

[0116] Next, the user may operate the hair dyeing device 100 to mix the dyes in the mixing chamber (S140). When the hair dyeing device 100 is operated and the first dye and the second dye are discharged into the mixing chamber 181, the hair dyeing device 100 starts to operate the second motor assembly 185 to mix the first dye with the second dye, thereby starting to generate the hair dye.

[0117] Finally, the user may operate the hair dyeing device 100 to discharge the hair dye generated by mixing to the outside of the hair dyeing device (S150). When the mixing chamber 181 is filled with the mixed hair dye due to the discharge and mixing of the first dye and the second dye, the hair dye moves through Figure 6 the chamber nozzle 182 shown in the figure into the inner space of the head 110. When the inner space of the head 110 is filled with the hair dye, the hair dye may move along the inner channels 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.

[0118] As described above, according to an embodiment of the present invention, the object of the present invention is to provide a hair dyeing device capable of mixing and using on-site the dyes constituting the hair dye.

[0119] The object of the present invention is to provide a hair dyeing device that can load the dyes in the cylinders without the need for direct injection.

[0120] The object of the present invention is to provide a hair dyeing device in which different types of comb teeth can be replaced according to the length of the hair.
