Meanwhile, the memory 50 includes a non-volatile storage device that keeps stored information even when power is not supplied and a volatile storage device that requires power to keep the stored information.
In addition, the present disclosure further includes a sensor module 40 for detecting a movement state on the hair of the hair printer 100, and a program may adjust an output state of an image in synchronization with information on the movement state on the hair of the hair printer 100. Specifically, the sensor module 40 may measure information on a movement speed on the hair or a movement distance from an image printing start point. For example, the sensor module 40 may be configured by an optical sensor or a rotation roller disposed at a position adjacent to a printer head of an upper housing of the hair printer 100, and detailed description thereof will be made below.
Specifically, the portable hair printer 100 according to the present disclosure further includes a housing 101 that houses the communication module 20, the printer module 10, the memory 50, and the processor 30. Here, the communication module 20 may support wireless communication or wired communication.

Here, the printer head 170 ejects dyeing ink so as to correspond to a type and the amount of ejection of the dyeing ink determined according to print data. For example, the dyeing ink may be composed of four types of C, M, Y, and W. In addition, the dyeing ink may include a pigment or dye as a colorant and include a nonionic surfactant or an ionic surfactant.
The printer module 10 may be configured in a form in which a replaceable ink cartridge of a general printer is embedded in the upper housing 102.
Referring to
That is, the sensor module 40 may detect a rotation speed of the rotation roller 140 coupled to the hair printer 100, may check a movement speed or a movement distance from a printing start point from this, and may adjust an image output state in synchronization with the movement speed or the movement distance.
As illustrated in
For example, the rotation roller 140 may disposed on one side of the printer head 170 provided on a lower surface of the upper housing 102 and may be formed to have a length corresponding to the printer head 170. In addition, the rotation roller 140 may be formed of a rubber material to have rotational friction when rolling over the hair and is not limited thereto.
For example, while a user grips hairs in a direction crossing a length direction of the hairs between the upper housing 102 and the lower housing 103, when the housing 101 of the hair printer 100 is slid from an upper side to a lower side of the hairs, the rotation roller 140 may rotate in a direction opposite to a movement direction of the housing 101.
At this time, the program executed by the processor 30 calculates a length of a bundle of hairs based on a value measured by the sensor module 40 as the portable hair printer 100 moves along the hairs while the hairs are gripped between the upper housing 102 and the lower housing 103 of the portable hair printer 100, and a value of the length of the bundle of hairs may be output through the display unit 150 coupled to the portable hair printer 100 or may be transmitted to the user terminal 200.
The sensor module 40 or an encoder may be used and may count the number of rotations of the rotation roller 140.
For example, the user terminal 200 may output a virtual screen whose image is converted in size to correspond to the length of bundle of hairs based on the calculated length of the bundle of hairs, and a user may select an image to be dyed while viewing the virtual screen. At this time, the image, which is selected by the user, is converted in size by the user terminal 200 to correspond to the length of the bundle of hairs and may be transmitted to the portable hair printer 100. Due to this, the portable hair printer 100 may obtain an optimal resolution of the dye image regardless of the length of the bundle of hairs of different users.
The hair measurement sensor 130 may measure a size of a bundle of hairs gripped between the upper housing 102 and the lower housing 103. For example, the hair measurement sensor 130 may be configured as a thickness measurement sensor that measures a thickness of the hair while the hair is gripped between the upper housing 102 and the lower housing 103, and for example, the thickness measurement sensor may be a distance sensor for measuring a distance between the upper housing 102 and the lower housing 103 or may be a pressure sensor for measuring a pressure applied to the upper housing 102 or the lower housing 103 by the hair. For example, the distance sensor may be composed of an infrared sensor or an ultrasonic sensor and is not limited thereto.
At this time, when a size of a bundle of hairs measured by the hair measurement sensor 130 is greater than or equal to a threshold, the program executed by the processor 30 may output an alarm to cause the hairs to be gripped again. Due to this, the upper housing 102 and the lower housing 103 may obtain an appropriate thickness of the hairs such that a high-quality image is printed.
Referring to
For example, the hair guide 110 may be formed to extend in a curved shape toward an upper side from the side surface of the lower housing 103. In addition, the hair guide 110 may be formed of a steel material and is not limited thereto.
The comb member 115 may disposed on the side surface of the upper housing 102 in an extension direction of the upper housing 102 in a region corresponding to the printer head 170 of the upper housing 102 to guide hairs to be evenly introduced. For example, the comb member 115 allows hairs to evenly spread through teeth of a comb, thus, preventing the hairs from getting tangled.
That is, the hair guide 110 and the comb member serve to fix hairs such that a certain size of a bundle of hairs is gripped between the upper housing 102 and the lower housing 103.
Meanwhile, the comb member 115 may be selectively attached or detached to or from one side of the upper housing 102 through a fastening member. In addition, various types of comb member 115 may be provided in the form of accessories, and an appropriate comb member 115 may be combined according to a user's selection. User convenience can be improved by allowing the appropriate comb member 115 to be replaced depending on the user's hair length, hair texture, hair style, and so on.

For example, the ink tank 300 may supply dyeing ink to the printer module 10 through an electric pump. The tube 310 serves as a path for transmitting dyeing ink, and the tube 310 that connects the ink tank 300 to the printer module 10 may be provided together with a power supply cable.
Referring to
As an example, the drying portion 180 may quickly dry the dyeing ink output onto hairs or the coating agent and may be composed of a heater, hot air, and infrared rays. The coating portion 190 may output a coating agent that assists the dyeing ink output onto hairs to be settled well on each hair or may output a nutritional agent containing ingredients for health care of a hair.
Meanwhile, the hair printer 100 may further include a cleaning unit 120 that slidably moves to a capping position for capping the printer head 170 and an uncapping position for dyeing.
For example, the cleaning unit 120 may include a wiping portion that wipes the ink on the printer head 170 while slidably moving in a state in contact with the printer head 170. In other words, the cleaning unit 120 not only serves as a cover to prevent the printer head 170 from being exposed to the outside when not in use, but also removes ink remaining in the printer head 170 through the wiping portion during sliding movement. For example, the number of wiping portions may correspond to the number of printer heads 170 and is not limited thereto.
In detail, when the hair printer 100 is used, the cleaning unit 120 may be slidably moved from the capping position to the uncapping position. At this time, when not in use, the wiping portion may wipe off the ink leaked from the printer head 170. In addition, when use of the hair printer 100 is completed, the cleaning unit 120 may be slidably moved from the uncapping position to the capping position. The wiping portion may wipe off the ink remaining in the printer head 170. For example, the wiping portion may be formed of a porous absorbent material such as a fiber or sponge capable of absorbing ink and is not limited thereto.
The cleaning unit 120 may include a capping portion that comes into close contact with the printer head 170 when the printer head 170 is capped. The capping portion is in close contact with a circumference of the printer head 170, and a central portion thereof is recessed to collect that ink dripping from the printer head 170, and thus, contamination due to ink may be prevented.
In addition, the wiping portion and the capping portion may be replaced as needed when used for a certain period of time. For example, a replacement cycle may be notified by an alarm through an application or by an alarm an apparatus itself.
The cleaning unit 120 may further include an opening/closing sensor for detecting whether the cleaning unit 120 is opened or closed. In addition, a user may check whether the cleaning unit 120 is opened or closed through the display unit 150. For example, when a predetermined time elapses in an uncapping state in which the printer head 170 is opened, the cleaning unit may raise an alarm to a user through the opening/closing sensor to prevent the printing head 170 from being dried.

The color development, durability improvement, and water resistance of an object were evaluated by processing black human hair by using a detachable device auxiliary device according to an embodiment of the present disclosure and the composition of examples 1 to 8.
In order for the main processing unit to perform a color developer application of the first color development auxiliary material according to Examples 1 to 4, the pre-processing unit 12 performed color masking (application and fixation of bright color) on an object, the main processing unit 11 performs a procedure of applying a predetermined color developer to the object, and the post-processing unit 13 performed application of a composition for color fixation and post-processing (heat treatment and so on), and thereby, durability was improved.
Color Development Evaluation
Red coloring matter (D&C RED 28) is output onto human hair by the main processing unit of the present disclosure. The optical density (OD) of dyed human hair was measured by using a spectroeye (GretagMacbeth company), which is a colorimetric densitometer, and evaluated according to the following standard, and the results are shown in Table 1 below. In spectroscopy, the optical density (OD) refers to a log value of a ratio (I0/I1) of the amount (T0) of emitted radiation to the amount of transmitted radiation (I1) when energy such as light is emitted onto a material.
By measuring the optical density, color vividness, which includes both brightness and saturation of a color, may be measured as an objective indicator, and accordingly, the objective indicator may be used as a standard for evaluating color development when dyeing hair.
Referring to Table 1, in Evaluation Examples 1 to 5, OD values are all 0.7 or greater, resulting in excellent hair color development, and thus, a target color is implemented. However, in Evaluation Examples 7 and 8, OD values are less than 0.7, resulting in insufficient hair color development.
Water Resistance Evaluation
In Evaluation Examples 1 to 8, a printed portion of the hair was immersed in water for 5 minutes, taken out, dried completely, and measured OD (OD wet), and then a percentage of the measured OD (ODbefore) was measured before immersed in water and was evaluated according to the following criteria, and the results are shown in Table 2 below.
Referring to Table 2, it can be seen that Evaluation Examples 1 to 5 have excellent water resistance because a difference in hair color development before and after soaking in water is less than in Evaluation Examples 6 to 8.
Abrasion Resistance Evaluation
In Evaluation Examples 1 to 8, the printed portion of the hair was rubbed five times to measure the OD (ODabbr), a percentage of the OD (ODbefore) measured before rubbing was calculated and evaluated according to the following criteria, and the results are shown in Table 3 below.
Referring to Table 3, it can be seen that Evaluation Examples 1 to 5 have excellent abrasion resistance because a difference in hair color before and after rubbing the hair is less than in Evaluation Examples 6 to 8.
Hereinafter, a hair printing method using the portable hair printer 100 according to the present disclosure will be described. Hereinafter, description on a configuration of performing the same function among the configurations illustrated in
Referring to
Specifically, the method may further include step S201 of calculating a length of a bundle of hairs based on a value measured through the sensor module 40 for detecting a movement state of the portable hair printer 100 as the portable hair printer 100 moves along the hairs while the hairs are gripped by using the upper housing 102 and the lower housing 103 of the portable hair printer 100 before step S210 of receiving an image is performed.
In addition, the method may further include step S202 of imaging or receiving a hair image of a person to be dyed by the user terminal 200, synthesizing a hair image and an image to be dyed which size is converted and provide it to the user terminal S200 before step S210 of receiving the image is performed.
For example, when a user selects an image to be dyed through the user terminal 200 after step S201, a virtual screen having an image converted in size to correspond to a length of a bundle of hairs of a user may be output and an image may be selected again by the user or image determination may be completed (S202). The user-determined image (that is, the image received in step S210) may be converted in size by the user terminal 200 to correspond to a length of a bundle of hairs, based on the length of the bundle of hairs calculated in step S201 (S203).
In step S220 of performing a printing operation, when a size of a bundle of hairs measured by the hair measurement sensor 130 that measures the size of a bundle of hairs gripped is greater than or equal to a threshold while the hairs are gripped between the upper housing 102 and the lower housing 103 of the portable hair printer 100, an alarm may be output to cause the hairs to be gripped again (S222).
For example, before step S222 is performed, whether the comb member 115 and the hair guide 110 are coupled to each other is checked while hairs are gripped between the comb member 115 disposed on a side surface of the upper housing 102 and the hair guide 110 disposed on a side surface of the lower housing 103, and when the hairs are not coupled such that the hairs are evenly introduced, an alarm may be output to cause the hairs to be gripped again (S221).
Then, the portable hair printer 100 may collect information on a movement state of the hair printer 100 on hairs, based on a value measured by the sensor module 40 that detects the movement state of the portable hair printer 100 as the portable hair printer 100 moves along the hairs, and adjust an output state of an image in synchronization with the collected information (S223).
Specifically, in step S223, the sensor module 40 may check a movement speed or a movement distance from a starting point by detecting a rotation speed of the rotation roller 140 coupled to the hair printer 100, and adjust the output state of the image in synchronization with the movement speed or the movement distance.
Step S220 may include step S224 of outputting a coating agent before and after dyeing ink is ejected through the coating portion 190 disposed adjacent to the printer module 10 and step S225 of drying the dyeing ink or the coating agent through the drying portion 180 disposed adjacent to the coating portion 190.
