Description

automatic dyeing machine

[0001] The present invention relates to an automatic hair dyeing machine, and more particularly, to an automatic hair dyeing machine that enables self-dyeing of hair simply, conveniently, at low cost and in a short time, while significantly reducing allergies, itching symptoms, inflammation and skin contamination.

[0002] As people age, their hair begins to gray, and by their mid-fifties, it's half-gray. Despite the aging population, the desire to look younger and more active in the workplace after their sixties has led many individuals to dye their hair. Furthermore, as people prioritize individuality, young people and middle-aged people often dye their hair in trendy colors.

[0003] Traditional hair dyeing involves either root dyeing at a professional establishment (e.g., a hair salon) or self-dyeing. Root dyeing involves dyeing strands of hair one at a time, starting from the root, and is expensive and time-consuming. Self-dyeing, which can be done at home, either by oneself or with the help of a friend, is less expensive. However, self-dyeing requires a lot of time. Furthermore, self-dyeing requires using a mirror, making it difficult to dye the sides, back, and inner hair, which are not visible.

[0004] The conventional hair dyeing process involves mixing a dye solution (oxidizing agent, hair dye) in a dye container with a dye brush, applying the dye solution to the hair with the dye brush, and combing it repeatedly with a dye comb. The dye solution contains various chemical raw materials, such as ammonia, hydrogen peroxide, PPD (paraphenylenediamine), 5-diamine, m-phenylenediamine, toluene-2 ​​sulfate, p-aminophenol, m-aminophenol, and other ingredients specific to the dye product.

[0005] Dyeing with dyes containing various chemical raw materials such as nickel, hexavalent chromium, lead, and PPD can cause side effects such as allergies, contact dermatitis, hives, convulsions, asthma, scalp diseases, edema, and hair loss in the dyed person, and the symptoms of these side effects become more severe with age.

[0006] Contact dermatitis is known to be a major side effect of hair dyeing. Contact dermatitis occurs when the hair dye comes into contact with the scalp in large quantities through a hair dye brush. Official data indicates that over 1,000 cases of hair dye-related harm have been reported.

[0007] The present invention has been devised to solve the above-described problem, and its purpose is to provide an automatic dyeing machine that prevents or minimizes contact of the dyeing solution with the skin surface during dyeing.

[0008] In addition, the present invention aims to provide an automatic dyeing machine that enables one to dye hair or eyebrows at a low cost in a short period of time.

[0009] In addition, the present invention aims to provide an automatic dyeing machine that uses a painting roller and a detachable hair comb to paint a dye solution on the surface and inside of hair, and evenly applies the dye solution to the painted hair with the detachable hair comb to enable even hair dyeing.

[0010] The technical problems to be achieved in the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0011] An automatic dyeing machine according to the present invention comprises a storage container for storing dyeing liquid with a long discharge hole in the left and right directions, a main frame coupled to the storage container on the upper surface and having open front and lower surfaces, a painting roller coupled to the main frame with a rotation shaft that rotates in a set direction within the main frame and is positioned below the discharge hole of the storage container coupled to the main frame, and a handle frame having a motor coupled to the main frame and rotating the painting roller in one direction therein.

[0012] In the above-described automatic dyeing machine, the main frame has a fixing groove on each of the left and right sides for coupling to the rotational axis of the painting roller, and the handle frame is coupled to the fixing groove on the left side to rotate the painting roller in a first direction via a motor, or is coupled to the fixing groove on the right side to rotate the painting roller in a second direction opposite to the first direction via a motor.

[0013] In the above-described automatic dyeing machine, a hair comb is further included, which is configured to be detachably attached to the main frame and is positioned below the open lower surface of the main frame when combined, and has a plurality of comb teeth facing from the rear of the lower surface to the front of the main frame.

[0014] In the above-mentioned automatic dyeing machine, the distance between the portion of the comb protruding forward from the main frame and the horizontal plane of the lowest part of the cylindrical painting roller is shorter than the distance between the portion of the comb located below the painting roller and the horizontal plane of the lowest part of the painting roller.

[0015] In the above-described automatic dyeing machine, the detachable comb on the main frame is a comb having a first distance between the plurality of teeth or a second distance between the plurality of teeth longer than the first distance, and the handle frame further includes a battery for supplying power to the motor and an on / off switch for driving the motor.

[0016] The automatic dyeing machine according to the present invention as described above has the effect of preventing the dye from contacting the skin surface or minimizing contact during dyeing.

[0017] In addition, the automatic dyeing machine according to the present invention as described above has the effect of enabling one to dye hair or eyebrows at a low cost in a short period of time.

[0018] In addition, the automatic dyeing machine according to the present invention as described above has the effect of painting the dyeing solution on the surface and inside of the hair using a painting roller and a detachable hair comb, and evenly applying the dyeing solution of the painted hair to the hair using the detachable hair comb, thereby enabling uniform hair dyeing.

[0019] The effects that can be obtained from the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the art to which the present invention belongs from the description below.

[0039] The above-described objects, features, and advantages will become more apparent through the detailed description set forth below with reference to the accompanying drawings, thereby enabling those skilled in the art to easily implement the technical concepts of the present invention. Furthermore, in describing the present invention, detailed descriptions of known technologies related to the present invention will be omitted if they are deemed to unnecessarily obscure the gist of the present invention. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0040]

[0041] Figure 1 is a drawing showing an example of an automatic dyeing machine (10) according to the present invention.

[0042] The automatic dyeing machine (10) according to the present invention is a handy machine that allows a user to directly dye hair (e.g., eyebrows, etc.) on the scalp or other parts of the body in a specific color (e.g., black, brown, yellow, etc.) according to a dyeing solution. The automatic dyeing machine (10) automatically dyes the scalp or hair with the help of a painting roller (500) provided therein.

[0043] An automatic dyeing machine (10) includes a storage container (100), a main frame (300), a painting roller (500), a handle frame (700), and a comb (900) that are combined to form a complete product, and a user holds the handle frame (700) and applies dyeing solution to the hair to be dyed by applying the dyeing solution to the hair using the provided comb (900) and the painting roller (500). The painting roller (500) of the automatic dyeing machine (10) rotates in one direction, and the dyeing solution applied to the painting roller (500) is applied to the hair (itself). The dyeing solution applied to the hair by combing with the provided comb (900) can be widely and evenly applied to the hair that is not applied with the dyeing solution by the painting roller (500).

[0044] As in the example of Fig. 1, the automatic dyeing machine (10) has a storage container (100) on the upper side (Y-axis) of the main frame (300), and the storage container (100) stores the dyeing solution. The storage container (100) has a discharge hole (110) that is long and short in the left-right direction (X-axis) on the lower side. The automatic dyeing machine (10) is configured so that a small amount of the stored dyeing solution continues to flow down in the downward direction (Y-axis) through the discharge hole (110).

[0045] The automatic dyeing machine (10) has a main frame (300) that is combined with other components and forms the shape of the automatic dyeing machine (10). The main frame (300) is configured to be combined with a storage container (100) through a combining means on the upper surface.

[0046] The automatic dyeing machine (10) further includes a painting roller (500) for applying (imbuing) a dye solution to the hair shaft. The rotational axis (510) of the painting roller (500) is coupled to the left and right sides of the main frame (300), and the painting roller (500) rotates according to the rotation of the rotational axis (510) in a direction set within the main frame (300).

[0047] The painting roller (500) is positioned below the discharge hole (110) of the storage container (100) coupled to the main frame (300) and can rotate in one direction the high viscosity dye solution that flows out through the discharge hole (110) and is applied to the surface of the painting roller (500).

[0048] The automatic dyeing machine (10) further includes a handle frame (700) that allows a user to hold it and perform various actions necessary for dyeing. The handle frame (700) includes a coupling means for coupling to the main frame (300) and a motor (730) for rotating a painting roller (500) in one direction therein, so that the painting roller (500) can be rotated in one direction (e.g., clockwise or counterclockwise) at a constant speed according to a user's operation while fixed to the main frame (300).

[0049] An automatic dyeing machine (10) is configured by combining a storage container (100), a main frame (300), a painting roller (500), and a handle frame (700). The user, while holding the handle frame (700), drives the motor (730) to rotate the painting roller (500), and uses a comb (900) to apply the dyeing solution flowing down from the storage container (100) to a specific location on the hair being dyed, thereby applying the dyeing solution to the hair by the rotation of the painting roller (500). In addition, the user can apply or apply the dyeing solution applied to the hair to a wider area by using the provided comb (900).

[0050] The automatic dyeing machine (10) has a three-dimensional shape and size that allows dyeing to be performed by the user's hand or by the hands of a nearby user. Each component of the automatic dyeing machine (10) will be examined in more detail in Fig. 2.

[0051]

[0052] Figure 2 is a drawing showing the specific shape of the components of an automatic dyeing machine (10).

[0053] Figure 2 (a) shows the shape and configuration of a storage container (100), Figure 2 (b) shows the shape and configuration of a main frame (300) and a painting roller (500), Figure 2 (c) shows the shape and configuration of a hair comb (900), and Figure 2 (d) shows the shape and configuration of a handle frame (700).

[0054] Looking at the components of the automatic dyeing machine (10) in more detail through Fig. 2, the storage container (100) is configured to store the dyeing solution and provide a certain amount of the stored dyeing solution to the lower painting roller (500) by being coupled to the main frame (300).

[0055] A storage container (100) made of metal or plastic material has container joining lines (130) on the left side, right side, and bottom side, and the container joining lines (130) on both sides can be separated or interlocked to open or close the storage container (100). A user can prepare the dyeing solution to be introduced to the painting roller (500) by introducing a dyeing solution mixed with an oxidizing agent and a hair dye into the opened storage container (100) using a dyeing brush or the like and closing the container joining lines (130).

[0056] The storage container (100) has a discharge hole (110) for discharging the dye solution stored on the lower surface downward. The discharge hole (110) has a shape that is long in the left-right direction and short in width (length in the front-back direction (Z-axis)). The dye solution, which is a high-viscosity liquid, flows down through the discharge hole (110) with a short width and can be continuously supplied in small quantities to the upper surface of the painting roller (500).

[0057] The storage container (100) has a coupling means for being fixed to the upper surface of the main frame (300). For example, the storage container (100) is configured to have one or two container coupling protrusions (150) on each of the two sides of the lower surface. The container coupling protrusions (150) can be inserted into corresponding grooves (310) of the main frame (300) so that the storage container (100) can be fixed to the main frame (300). The storage container (100) and the main frame (300) can be fixed to each other by other known automatic or manual coupling means in addition to the container coupling protrusions (150) and their grooves (310).

[0058] The main frame (300) has a space for accommodating a painting roller (500) therein and is combined with various other components to form an automatic dyeing machine (10). The main frame (300), which is made of metal or the like, has an open front (see E), an upper surface (see A), and a lower surface (see F). The left side (see D), the right side (see C), and the rear side (see B) of the main frame (300) preferably have a closed shape.

[0059] The main frame (300) has a plurality of coupling means for coupling with other components. The main frame (300) may have an automatic or manual configuration for detachably coupling or separating with other components. For example, the main frame (300) has one or more container coupling grooves (310) on both sides of the upper surface into which a container coupling protrusion (150) of a storage container (100) can be inserted. The main frame (300) may be made of a plastic material or a metal material.

[0060] In addition, the main frame (300) has a fixed groove (350) of the same shape on each of the left side and the right side (center) for coupling with the handle frame (700). The fixed groove (350) of the main frame (300) is coupled to the central rotational axis of the painting roller (500), and the painting roller (500) rotates clockwise (e.g., forward-backward direction) or counterclockwise (e.g., backward-forward direction) by the rotational force of the handle frame (700) (motor (730)) coupled through the fixed groove (350).

[0061] Additionally, the main frame (300) has one or more comb-joining grooves (370) on each side of the lower surface for engaging with a hair comb (900). The hair comb (900) is fixed through the comb-joining grooves (370), thereby enabling dyeing of hair (or both hairs).

[0062] The painting roller (500) located inside the main frame (300) rotates in one direction according to the rotational force of the handle frame (700) that is coupled through the fixed grooves (350) on the left and right sides at both ends of the provided rotational shaft (510). The painting roller (500) that receives the rotational force through the fixed groove (350) on the left side rotates at a constant speed in a first direction (e.g., clockwise). In addition, the painting roller (500) that receives the rotational force through the fixed groove (350) on the right side rotates at a constant speed in a second direction (e.g., counterclockwise) that is opposite to the first direction.

[0063] The painting roller (500) is cylindrical and has a long shape in the left-right direction, and its body is made of metal. Depending on the design variation, the surface of the cylindrical body of the painting roller (500) may have a configuration for applying the dye well to the hair. For example, the painting roller (500) may have a PBT (Polybutylene terephthalate) type brush on the surface of the body. The PBT type brush may have a diameter of 0.1 mm to 0.5 mm and a length of 10 mm to 30 mm. Since the painting roller (500) has a PBT brush that is elastic, durable, and soft, the dyeing power of the automatic dyeing machine (10) can be preferably increased. Alternatively, a suede material may be attached to the surface of the cylindrical body of the painting roller (500). Since the surface of the cylindrical body of the painting roller (500) has a suede material, the dyeing power of the automatic dyeing machine (10) is also increased.

[0064] The comb (900) is configured to be detachable from the automatic dyeing machine (10). The comb (900) is preferably configured to be detachable from the main frame (300). When coupled to the main frame (300), the comb (900) is positioned below the open lower surface of the main frame (300). The comb (900) has, for example, one or more comb-engaging protrusions (910) at both ends on the left and right sides and at the rear end. The comb (900) is positioned and fixed below the lower surface of the main frame (300) through a coupling means such as the comb-engaging protrusions (910) and the comb-engaging grooves (370) of the painting roller (500).

[0065] The comb (900) has a plurality of comb teeth (950) that face from the rear of the lower surface of the main frame (300) toward the front of the main frame (300) between the left and right ends. The length of the comb teeth (950) protruding forward from the front of the main frame (300) (see l) may be between about 23 mm and 35 mm, and the spacing between the comb teeth (950) (see d) may be between 1 mm and 3.5 mm. The diameter of the comb teeth (950) may be 0.9 mm or less.

[0066] Here, the automatic dyeing machine (10) is preferably configured to be equipped with several types of combs (900) and each comb (900) is detachably attached to the automatic dyeing machine (10). Accordingly, a comb (900) suitable for the type of hair (long hair, short hair, etc.) is attached to the automatic dyeing machine (10) to enable efficient hair dyeing.

[0067] For example, one comb (900) has a spacing between teeth (950) of 1 to 2 mm and is thus preferably used for dyeing short hair (e.g., men). Another comb (900) has a spacing between teeth (950) of 2.5 to 3.5 mm and is thus preferably used for dyeing long hair (e.g., women).

[0068] Hair dyeing is performed by contact between the surface of the painting roller (500) and the hair in the space between the surface of the rotating body of the painting roller (500) and the plurality of comb teeth (950). The hair comb (900) according to the present invention is configured to take this dyeing structure into consideration. The hair comb (900) according to the present invention is configured so that a large space can be secured between the comb teeth (950) and the rotating body surface of the painting roller (500).

[0069] As can be seen in (c) of FIG. 2, the distance between the horizontal plane (see ⓐ) in contact with the lowermost surface of the cylindrical body of the painting roller (500) and the (end) portion of the comb teeth (950) protruding forward from the main frame (300) of the comb teeth (950) (see h1) is configured to be shorter than the distance between the portion of the comb teeth (950) located directly below the lowermost portion of the body cylinder of the painting roller (500) (the point where they meet vertically at the lowermost portion of the body cylinder) (see h2). Preferably, the diameter of the front comb teeth (950) including the end is configured to be larger than the diameter of the rear comb teeth (950).

[0070] Accordingly, the automatic dyeing machine (10) conveniently guides or sets the dyeing position of the hair by the comb (900) with the protruding end of the comb teeth (950), and ensures that the dyeing is smoothly performed without the hair (hair) getting caught, etc., by securing sufficient dyeing space between the body of the painting roller (500) and the inner comb teeth (950).

[0071] The automatic dyeing machine (10) further includes a handle frame (700), which may be configured to include an on-off switch (710), a motor (730), a battery (750), and a coupling terminal (770). The handle frame (700) has a case made of a plastic material or a metal material and accommodates a motor (730) and a battery (750) for supplying power to the motor (730) therein. The handle frame (700) may have an on-off switch (710) and a coupling terminal (770) for driving the motor (730) on the surface of the case.

[0072] When turned on by an on / off switch (710) of a push button type, the handle frame (700) can apply power from the battery (750) to the motor (730) to rotate the motor (730). In addition, when turned off by the on / off switch (710), the handle frame (700) can stop the operation of the motor (730).

[0073] The battery (750) may be a small dry cell or a lithium-ion battery (750), and the motor (730) may rotate at a constant speed according to the power supplied by the battery (750). The motor (730) may have a reducer inside. The motor (730) may rotate the rotation shaft at a speed of, for example, 30 to 120 RPM.

[0074] The handle frame (700) has a connecting terminal (770) and is connected to the main frame (300). The connecting terminal (770) of the handle frame (700) can be connected and fixed to the fixing groove (350) of the main frame (300). The connecting terminal (770) and the fixing groove (350) fix the handle frame (700) and the main frame (300) to each other in various known ways. The output (rotation) shaft of the motor (730) is connected to the rotation shaft (510) of the painting roller (500), and the rotation shaft (510) is rotated by the motor (730), and the painting roller (500) is rotated accordingly.

[0075] For example, the handle frame (700) can be coupled to a fixed groove (350) located on the left side of the main frame (300) and the painting roller (500) can be rotated in a first direction (e.g., clockwise) by rotation of the internal motor (730) in a fixed direction. In addition, the handle frame (700) can be coupled to a fixed groove (350) located on the right side of the main frame (300) and the painting roller (500) can be rotated in a second direction (e.g., counterclockwise) opposite to the first direction by rotation of the internal motor (730) in a fixed direction.

[0076] Accordingly, the position of the handle frame (700) can be conveniently changed depending on the user's handle type (e.g., left-handed, right-handed) and the position of the hair to be dyed, enabling smooth hair dyeing.

[0077]

[0078] Figure 3 is a drawing showing a process of dyeing hair using an automatic dyeing machine (10).

[0079] To dye hair, first, the user connects (S10) the comb (900), the main frame (300), and the handle frame (700) using the provided connecting means. For example, the user inserts one or more comb connecting protrusions (910) of the comb (900) into the comb connecting grooves (370) of the main frame (300) to secure the comb (900) to the lower side of the main frame (300). In addition, the user connects the connecting terminals (770) of the handle frame (700) to the fixing grooves (350) on the left or right side of the main frame (300) to secure the handle frame (700) to the main frame (300). The handle frame (700) may be located on the left or right side of the main frame (300). For simplicity, the coupling means is exemplified by a groove and projection coupling method, but various known coupling structures can be used for coupling between the main frame (300), the handle frame (700), and the hair comb (900).

[0080] Additionally, the user mixes an oxidizing agent and a dye to create a dye solution and pours the dye solution into a storage container (100) (S20). The user can separate the container joining line (130) and pour the created dye solution into the open storage container (100). After pouring the dye solution into the storage container (100), the user joins the container joining line (130).

[0081] The user attaches (S30) a storage container (100) containing a dye solution to the main frame (300). For example, the user can insert one or more container attachment protrusions (150) of the storage container (100) into the container attachment grooves (310) of the main frame (300) to fix the storage container (100) and the main frame (300) to each other. Upon attachment, the storage container (100) is positioned on the upper side of the main frame (300), and the dye solution discharge hole (110) of the storage container (100) is positioned on (in contact with) the upper surface of the main frame (300).

[0082] As the assembly of the automatic dyeing machine (10) is completed, the user turns on (S40) the on-off switch (710) of the handle frame (700). As the on-off switch (710) of the handle frame (700) is turned on, the user can proceed with hair dyeing.

[0083] Looking into it more specifically, as the on-off switch (710) is turned on, the painting roller (500) coupled to the rotational axis of the motor (730) of the handle frame (700) rotates at a constant speed (e.g., 30 to 120 RPM), and the dye solution (a constant small amount) injected through the discharge hole (110) is applied (S50) to the surface of the painting roller (500) in contact with the discharge hole (110). As the painting roller (500) rotates, the dye solution applied to the surface rotates along the cylindrical surface of the painting roller (500) at a constant speed.

[0084] The user divides the hair to be dyed with the hair comb (900) provided in the automatic dyeing machine (10), brings the painting roller (500) into contact with the hair to be dyed in a certain area inside the divided hair, and dyes the hair (hair) located between the hair comb (900) and the painting roller (500) (S60) according to the rotation of the painting roller (500).

[0085] The automatic dyeing machine (10) is configured such that the distance (h2) between the lowermost surface of the body of the painting roller (500) and the comb (900) is longer than the distance (h1) between the front end of the comb (900) and the horizontal plane of the lower surface. Accordingly, the automatic dyeing machine (10) can position the painting roller (500) on the hair to be dyed using the end of the comb (900), and performs dyeing by applying the dye to the hair passing through the space secured between the body of the painting roller (500) and the comb (900). In addition, the automatic dyeing machine (10) can smoothly dye the hair without entangling or twisting the hair even when the painting roller (500) rotates due to the relatively wide space secured between the body of the painting roller (500) and the comb (900) compared to the end of the comb (900).

[0086] The user can comb the hair with the provided comb (900) and repeatedly dye the hair (S70) multiple times. In addition, the user can perform a thorough dyeing by repeatedly combing the hair up and down, left and right, front and back, etc. with the comb (900).

[0087] As dyeing is completed, the user can turn off the on / off switch (710) (S80) to stop the operation of the motor (730), separate the comb (900), storage container (100) and further the painting roller (500) of the automatic dyeing machine (10), and wash and dry the main components.

[0088] The automatic dyeing machine (10) according to the present invention can dye hair on its own and minimize dyeing costs. Furthermore, the automatic dyeing machine (10) is configured to allow combs (900) of various shapes to be attached to the main frame (300), thereby enabling dyeing of various types of hair, such as long hair, short hair, and eyebrows. Furthermore, the automatic dyeing machine (10) can dye hair in a relatively short time.

[0089] The automatic dyeing machine (10) according to the present invention uses a painting roller (500) instead of a dyeing brush to automatically apply the dye solution applied to the painting roller (500) to the hair shaft, thereby performing dyeing. In other words, the dye solution is prevented from coming into contact with the skin of the hair (e.g., the scalp) or the contact area thereof is minimized. Accordingly, the automatic dyeing machine (10) can eliminate or minimize various side effects (dye solution contamination, allergies, contact dermatitis, etc.) that occur when the dye solution comes into contact with the skin of the hair.

[0091] Figure 4 is a drawing showing the state of the scalp after dyeing using a conventional dyeing machine and an automatic dyeing machine (10) according to the present invention.

[0092] Fig. 4 (a) is an image showing the scalp condition of hair photographed after dyeing with an automatic dyeing machine (10) according to the present invention and washing the hair multiple times, and Fig. 4 (b) is an image showing the scalp condition of hair photographed after dyeing with a known dyeing method and washing the hair multiple times.

[0093] As can be seen from the images (a) and (b) of FIG. 4, the automatic dyeing machine (10) according to the present invention can be seen to have almost no dye solution on the scalp or pores of dyed hair. On the other hand, it can be seen that a large amount of dye solution remains on the scalp or pores of hair dyed through conventional dyeing (see the circular mark in (b) of FIG. 4). The large amount of dye solution remaining causes various side effects.

[0094] In this way, the automatic dyeing machine (10) according to the present invention minimizes allergies, itching, and inflammation. Furthermore, the automatic dyeing machine (10) enables quick, inexpensive dyeing, reduces contamination of areas such as the earlobes, face, and back of the neck caused by hair dyeing, and allows anyone, regardless of age or gender, to easily dye various types of hair.

[0095] The present invention described above is not limited to the above-described embodiments and the attached drawings, as various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention by a person having ordinary skill in the art to which the present invention pertains.
