Description

A dyeing machine capable of mixing dye and oxidizing agent

[0001] The present invention relates to a dyeing machine, and more particularly, to a dyeing machine that automatically and conveniently mixes and discharges a dyeing agent and an oxidizing agent used for hair dyeing.

[0002]

[0003] The number of people dyeing their hair for cosmetic purposes or to hide gray or blemishes is increasing. Dyeing involves mixing a dye and an oxidizing agent, applying it to the hair, and leaving it to sit for a certain amount of time.

[0004] At this time, the dye and oxidizer are each packaged in separate tube containers, and the user or hairdresser who wishes to dye the hair squeezes the dye and oxidizer into one container, mixes the dye and oxidizer manually using a brush, and then applies it to the hair.

[0005] This process of mixing dye and oxidizer requires a separate container, and there was a limitation that it was difficult for non-experts to evenly mix the dye and oxidizer.

[0006]

[0007] The purpose of the present invention is to solve the above-described problem, and to provide a dyeing machine that uniformly mixes and discharges a dye and an oxidizing agent, thereby enabling a user to easily use the dye for hair dyeing.

[0008] Another object of the present invention is to provide a dyeing machine capable of preventing further leakage of dye by removing residual pressure remaining inside a cylinder when pressure on a plunger is released during dye discharge.

[0009] The above objects and various advantages of the present invention will become more apparent to those skilled in the art from the preferred embodiments of the present invention.

[0010]

[0011] The above-described object of the present invention can be achieved by a dyeing machine capable of mixing and discharging a dye and an oxidizing agent. The dyeing machine of the present invention comprises: a cartridge (110) having a dye cylinder (111) and an oxidizing agent cylinder (113) which are arranged side by side and each accommodates a dye and an oxidizing agent, and a dye discharge pipe (111a) and an oxidizing agent discharge pipe (113a) are formed at the front; a mixing tip outer case (140) which is coupled to the front of the cartridge (110) and discharges the dye and the oxidizing agent to the outside; a mixing member (150) which is coupled to the inside of the mixing tip outer case (140) so as to cover the dye discharge pipe (111a) and the oxidizing agent discharge pipe (113a) and mixes the dye discharged through the dye discharge pipe (111a) with the oxidizing agent discharged through the oxidizing agent discharge pipe (113a); It is characterized by including a plunger (160) that is inserted into the rear of the dye cylinder (111) and the oxidizer cylinder (113), and moves forward by pressure to discharge the dye and the oxidizer into the mixing tip outer case (140).

[0012] According to one embodiment, the device may further include a sealing socket (120) that blocks the dye discharge pipe (111a) and the oxidizing agent discharge pipe (113a) when the dye and the oxidizing agent are not in use, thereby preventing external discharge of the dye and the oxidizing agent; and a socket outer cap (130) into which the sealing socket (120) is press-fitted.

[0013] According to one embodiment, the plunger (160) includes a pair of plunger bodies (161) having tips inserted into the rear of the dye cylinder (111) and the oxidizer cylinder (113); a pair of front coupling members (163) coupled to the front of the pair of plunger bodies (161), wherein the front coupling members (163) include a front pressure plate (163a) having an outer diameter corresponding to the inner diameters of the dye cylinder (111) and the oxidizer cylinder (113); a rear support plate (163b) provided at a predetermined distance from the front pressure plate (163a) and supported in contact with the plunger body (161); and a guide shaft (163c) provided between the front pressure plate (163a) and the rear support plate (163b). It may include a residual pressure removal ring (165) that is coupled to the above guide shaft (163c) and moves back and forth along the outer surface of the above guide shaft (163c) and removes the residual pressure inside when the pressure applied to the plunger (160) is released, thereby preventing further leakage of the dye and oxidizing agent.

[0014] According to one embodiment, the guide shaft (163c) is formed so that its outer diameter gradually increases toward the rear, and an expansion wing (163d) whose width and thickness gradually increase along the longitudinal direction may be provided along the circumferential direction on the outer surface of the guide shaft (163c).

[0015]

[0016] The dye cartridge assembly according to the present invention stores dye and oxidizer in cartridges respectively, and when in use, mixes them evenly using a mixing tip outer case and a mixing member and discharges them to the outside.

[0017] Accordingly, the conventional process of users squeezing the dye and oxidizer into a container and then mixing them with a brush can be omitted.

[0018] In particular, it has the advantage of being able to discharge only the amount of dye mixture desired by the user by removing the internal residual pressure through the residual pressure removal ring.

[0019] Additionally, it has the effect of being able to be used to part hair when dyeing hair by using a mixer tube that protrudes forward by a certain length.

[0030] To fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. These embodiments are provided to more completely explain the present invention to those with average knowledge in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that in each drawing, the same parts are sometimes depicted with the same reference numerals. Detailed descriptions of well-known functions and configurations that may unnecessarily obscure the gist of the present invention are omitted.

[0031]

[0032] FIG. 1 is a perspective view showing the configuration of a dyeing agent discharge state of a dyeing machine (100) according to the present invention, FIG. 2 is a perspective view showing the configuration of a storage state of a dyeing machine (100), FIG. 3 is an exploded perspective view showing the configuration of a dyeing machine (100) in an exploded manner, and FIG. 4 is a cross-sectional view showing the cross-sectional configuration of a dyeing agent discharge state of a dyeing machine (100).

[0033] As shown, the dyeing machine (100) according to the present invention comprises a cartridge (110) in which a pair of cylinders (111, 113) each containing a dyeing agent (A) and an oxidizing agent (B) are combined, a sealing socket (120) and a socket outer cap (130) which are combined at the front end of the cartridge (110) to prevent external discharge of the dyeing agent (A) and the oxidizing agent (B) when storing the dyeing agent (A) and the oxidizing agent (B), a mixing tip outer case (140) and a mixing member (150) which are combined at the front end of the cartridge (110) to mix the dyeing agent (A) and the oxidizing agent (B) and discharge them to the outside by removing the sealing socket (120) and the socket outer cap (130), and are respectively combined at the rear of a pair of cylinders (111, 113) and are pressed by an external force and move forward to form a pair of It includes a pair of plungers (160) that allow the dye (A) and oxidizer (B) inside the cylinder (111, 113) to be discharged to the outside.

[0034] When the dyeing machine (100) according to the present invention is stored in a state where no dyeing agent or oxidizing agent is used, as shown in FIG. 2, a sealing socket (120) and a socket outer cap (130) are combined with the cartridge (110) to prevent the dyeing agent and oxidizing agent from being discharged.

[0035] On the other hand, when the dyeing agent and oxidizing agent need to be discharged for dyeing, as shown in Fig. 1, a sealing socket (120) and a socket outer cap (130) are combined in a cartridge (110) to discharge a dyeing mixture (A+B) in which the dyeing agent (A) and the oxidizing agent (B) are uniformly mixed to the outside. This eliminates the hassle of the user having to manually squeeze the dyeing agent (A) and the oxidizing agent (B) into a container and then mix them, and has the effect of allowing even non-experts to uniformly mix the dyeing agent and the oxidizing agent.

[0036] In addition, the dyeing machine (100) according to the present invention has a residual pressure relief ring (165) coupled to the plunger (160) to move the plunger (160) so that the dye is discharged in an amount suitable for the user's use, and when the pressure is released, the plunger (160) is moved backward by elastic force to remove the residual pressure. This has the effect of preventing the dye and oxidizer from leaking due to the residual pressure and discharging only an accurate amount to the outside.

[0037]

[0038] The cartridge (110) independently stores the dye (A) and the oxidizer (B) and supports the discharge of the dye (A) and the oxidizer (B) by the pressurization of a pair of plungers (160). The cartridge (110) is configured by connecting a dye cylinder (111) containing the dye (A) and an oxidizer cylinder (113) containing the oxidizer (B) in parallel.

[0039] The dye cylinder (111) and the oxidizer cylinder (113) are fixed as one piece by being attached at one end, and are connected to each other at the bottom by a lower flange (117). A dye discharge pipe (111a) through which dye (A) is discharged is formed at the front of the dye cylinder (111), and an oxidizer discharge pipe (113a) through which oxidizer (B) is discharged is formed at the front of the oxidizer cylinder (113).

[0040] A pair of cap fixing wings (115) are provided facing each other in the front of the dye cylinder (111) and the oxidizing cylinder (113) in which the dye discharge pipe (111a) and the oxidizing agent discharge pipe (113a) are respectively formed, to which the socket outer cap (130) and the mixing tip outer case (140) are detachably fixed. The cap fixing wings (115) are provided with a cap fixing protrusion (115a) in the shape of the letter “ㄱ” to support and move the cartridge coupling ribs (135, 142) of the socket outer cap (130) and the mixing tip outer case (140) inside.

[0041] The lower flange (117) integrally connects the lower portions of the dye cylinder (111) and the oxidizer cylinder (113). The lower flange (117) is formed to extend horizontally with a certain area radially outward from the lower portions of the dye cylinder (111) and the oxidizer cylinder (113).

[0042]

[0043] The sealing socket (120) and the socket outer cap (130) are used to store the dye (A) and the oxidizer (B) so that they are not discharged to the outside, as shown in Fig. 2. As shown in Fig. 3, the sealing socket (120) blocks and seals the dye discharge pipe (111a) and the oxidizer discharge pipe (113a). The socket outer cap (130) is fixed to the outside of the sealing socket (120) so that the user can hold it by hand and rotate it to remove the sealing socket (120) from the cartridge (110).

[0044] The sealing socket (120) includes a socket body (121) that is press-fitted and fixed inside the socket outer cap (130) in the shape of a disk, a first discharge pipe plug (123) and a second discharge pipe plug (125) that are provided at the rear of the socket body (121) and into which a dye discharge pipe (111a) and an oxidizer discharge pipe (113a) are inserted, and a dye tip support rib (127) that is provided to protrude at the front of the socket body (121).

[0045] The first discharge pipe stopper (123) and the second discharge pipe stopper (125) are inserted into the dye discharge pipe (111a) and the oxidizer discharge pipe (113a), respectively, to seal the dye discharge pipe (111a) and the oxidizer discharge pipe (113a).

[0046] The dye tip support rib (127) protrudes forward from the socket body (121) by a certain length. A dye color indicating tip (128) is attached to the tip of the protruding dye tip support rib (127) to externally display the color of the dye (A).

[0047] The dye color indicating tip (128) is provided with the color of the dye (A) contained in the dye cylinder (111). As shown in an enlarged view in Fig. 2, the dye color indicating tip (128) is contained in the tip exposure hole (133a) of the socket outer cap (130) in a storage state and externally indicates the color of the dye (A) contained in the dye cylinder (111).

[0048]

[0049] The socket outer cap (130) is connected to the tip of the cartridge (110) while containing the sealing socket (120) inside. The socket outer cap (130) is provided with a socket outer cap body (131) into which the sealing socket (120) is press-fitted and fixed, and an outer cap handle (133) that is formed protruding from the tip of the socket outer cap body (131) and contains a dyeing tip support rib (127).

[0050] The socket outer cap body (131) is fixed in position by being inserted between a pair of cap fixing wings (115) of the cartridge (110) as shown in Fig. 2. The lower outer surface of the socket outer cap body (131) is provided with a pair of first cartridge coupling ribs (135) that rotate along the circumferential direction and are inserted into the cap fixing wings (115).

[0051] The first cartridge coupling rib (135) is formed lower than the height of the cap fixing wing (115) so that the socket outer cap body (131) can be rotated 90 degrees through the inside of the cap fixing wing (115). A first additional rotation prevention rib (135a) having a height higher than the cap fixing wing (115) is provided at the end of the first cartridge coupling rib (135) so as to be in contact with and supported by the cap fixing wing (115).

[0052] In this way, the first additional rotation prevention rib (135a) is supported by contact with the cap fixing wing (115) and prevents the socket outer cap (130) from further rotating at an angle of 90 degrees or more.

[0053] The outer cap handle (133) protrudes on both sides so that the user can hold the outer cap handle (133) and rotate the socket outer cap body (131) in the forward and reverse directions to fix or separate it from the cartridge (110) together with the sealing socket (120).

[0054]

[0055] The mixing tip outer case (140) and the mixing member (150) are coupled to the tip of the cartridge (110) as illustrated in Fig. 1 when the dyeing mixture (A+B) containing the dye (A) and the oxidizing agent (B) must be discharged externally for hair dyeing. At this time, the user removes the socket outer cap (130) and the sealing socket (120) from the cartridge (110) and couples the mixing member (150) and the mixing tip outer case (140) to the cartridge (110).

[0056] The mixing tip outer case (140) is coupled to the cartridge (110) and guides the dye (A) and the oxidizing agent (B) supplied independently from the cartridge (110) to be mixed with each other and supplied to a container for dyeing or a dyeing area. The mixing tip outer case (140) includes a tip body (141) coupled to the cartridge (110), a mixing member (150) receiving tube (143) which receives the dyeing mixture (A+B) and guides it, and a tip color code handle (145) which is coupled between the mixing member receiving tube (143) and the tip body (141) and fixes the position of the tip body (141).

[0057] The tip body (141) is a cylindrical body with an open lower area and is coupled to the front of the cartridge (110). The tip body (141) accommodates a mixing socket (151) of a mixing member (150) therein, and guides the dye (A) and oxidizing agent (B) discharged through the mixing socket (151) to flow into the mixing member receiving tube (143) and be mixed by the mixing member (150).

[0058] The outer surface of the tip body (141) is provided with a second cartridge coupling rib (142) and a second additional rotation prevention rib (142a) that are coupled between the cap fixing wing (115) of the cartridge (110). The configuration of the second cartridge coupling rib (142) and the second additional rotation prevention rib (142a) is the same as that of the first cartridge coupling rib (135) and the first additional rotation prevention rib (135a) of the socket outer cap (130) described above.

[0059] The mixing member receiving tube (143) receives the mixing member (150) and provides a space in which the dye (A) and the oxidizing agent (B) can be mixed. As illustrated in FIG. 7, the mixing member receiving tube (143) has an inner diameter corresponding to the diameter of the mixing element (155) of the mixing member (150), thereby forming an inner space in which the dye (A) and the oxidizing agent (B) cannot move forward without passing through the mixing element (155). At the end of the mixing member receiving tube (143), a mixture discharge hole (143a) through which the dye mixture (A+B) is discharged is formed, so that the dye mixture (A+B), in which the dye (A) and the oxidizing agent (B) are mixed with each other, is discharged to the outside.

[0060] The tip color code handle (145) is provided at the boundary area between the tip body (141) and the mixing member receiving tube (143). As shown in Fig. 3, a pair of handle fixing ribs (141b) are provided on the front of the tip body (141) to protrude on both sides with the mixing member receiving tube (143) as the center.

[0061] The tip color code handle (145) accommodates a pair of handle fixing ribs (141b) inside as illustrated in Fig. 1. The tip color code handle (145) is provided with the same color as the dye (A) accommodated in the dye cylinder (111), thereby allowing the user to recognize the color of the dye (A) currently being used.

[0062] In addition, the tip color code handle (145) is provided in the form of a handle with a certain wide area formed on both sides, so that the user can hold it with his hand and rotate the mixing tip outer case (140) forward and backward to combine or separate it from the cartridge (110).

[0063]

[0064] The mixing member (150) is provided inside the mixing tip outer case (140) and mixes the dye (A) and the oxidizing agent (B) that are independently discharged from the cartridge (110). The mixing member (150) includes a mixing socket (151) accommodated inside the tip body (141), a dye transport pipe (152) and an oxidizing agent transport pipe (153) that are provided at the rear of the mixing socket (151) and are respectively connected to the dye discharge pipe (111a) and the oxidizing agent discharge pipe (113a), and a mixing element (155) that protrudes a certain length in front of the mixing socket (151) and is accommodated in the mixing member receiving pipe (143) and mixes the dye (A) and the oxidizing agent (B) discharged through the mixing socket (151).

[0065] The mixing socket (151) is press-fitted and fixed into the inside of the tip body (141) as illustrated in Fig. 7. The outer wall surface of the mixing socket (151) is press-fitted into the inner wall surface of the tip body (141). The outer coupling rib (151a) formed on the outer wall surface of the mixing socket (151) is press-fitted into the inner separation prevention rib (141a) formed on the inner wall surface of the tip body (141) and is integrally joined. The mixing socket (151) is attached and detached together with the tip body (141) while remaining attached to the mixing socket (151) when the tip body (141) is attached and detached from the cartridge (110).

[0066] The dye transport pipe (152) and the oxidizer transport pipe (153) are respectively connected to the dye discharge pipe (111a) and the oxidizer discharge pipe (113a) of the cartridge (110). A dye supply hole (152a) connected to the dye transport pipe (152) and an oxidizer supply hole (153a) connected to the oxidizer transport pipe (153) are formed on the front of the mixing socket (151).

[0067] The dye (A) and oxidizer (B) discharged through the dye supply hole (152a) and the oxidizer supply hole (153a), respectively, are moved to the mixing member receiving tube (143) and are moved via the mixing element (155) arranged in the mixing member receiving tube (143).

[0068] The mixing element (155) allows the dye (A) and the oxidizer (B) supplied from the dye supply hole (152a) and the oxidizer supply hole (153a) to be mixed and moved. The mixing element (155) has screw blades formed in a spiral direction along the length direction. The dye (A) and the oxidizer (B) move through the space between the mixing element (155) and the mixing member receiving tube (143) by the discharge pressure, are mixed with each other, and are discharged to the outside of the mixing member receiving tube (143).

[0069]

[0070] The plunger (160) is inserted into the rear end of the dye cylinder (111) and the oxidizer cylinder (113) of the cartridge (110), and advances along the inner wall of the dye cylinder (111) and the oxidizer cylinder (113) by the user's pressure, thereby pressurizing the dye (A) and the oxidizer (B) to be discharged through the dye discharge pipe (111a) and the oxidizer discharge pipe (113a). The plunger (160) includes a pair of plunger bodies (161) provided in a rod shape, a pair of front coupling members (163) coupled to the front of the pair of plunger bodies (161) to pressurize a dye (A) and an oxidizer (B), and a residual pressure removal ring (165) coupled to the front coupling members (163) to elastically move back and forth in conjunction with the forward and backward movement according to the pressurization of the plunger (160) to remove residual pressure.

[0071] As illustrated in FIGS. 3 and 4, a pair of plunger bodies (161) are inserted into the rear end of the dye discharge pipe (111a) and the oxidizer discharge pipe (113a), respectively. A front coupling plate (161a) for contacting and supporting a front coupling member (163) is provided at the front of the pair of plunger bodies (161). A pressure member coupling shaft (161c) is protruded and formed in the central region of the front coupling plate (161a). As illustrated in FIG. 4, the pressure member coupling shaft (161c) is inserted into the front coupling member (163) so that the front coupling member (163) is fixed to the plunger body (161).

[0072] A rear flange (161b) is provided at the rear of a pair of plunger bodies (161). The rear flanges (161b) are integrally connected to the plunger bodies (161) in pairs, allowing a user to simultaneously move a pair of plunger bodies (161) by pressing the rear flanges (161b).

[0073]

[0074] The front engaging member (163) moves while pressurizing the dye (A) and the oxidizing agent (B) when the plunger body (161) moves forward. The front engaging member (163) includes a front pressure plate (163a), a rear support plate (163b) that is provided spaced apart from the front pressure plate (163a) and is supported in contact with the front engaging plate (161a), and a guide shaft (163c) that is provided between the front pressure plate (163a) and the rear support plate (163b) and supports a residual pressure removal ring (165).

[0075] As shown in the enlarged view in Fig. 3, the guide shaft (163c) is provided with an outer diameter that gradually increases from the front to the rear. The guide shaft (163c) moves forward by the pressure of the plunger body (161), and the residual pressure relief ring (165) coupled to the outer surface moves backward and supports it by elastically stretching.

[0076] Fig. 6 (a) is a cross-sectional view taken along line AA of the enlarged drawing of Fig. 3, and Fig. 6 (b) is a cross-sectional view taken along line BB of the enlarged drawing of Fig. 3.

[0077] Expansion wings (163d) are provided on both sides of the guide shaft (163c). The expansion wings (163d) are provided so that their width and thickness gradually increase from the front to the rear of the guide shaft (163c). As illustrated in (a) of Fig. 6, the frontmost cross-sectional shape of the guide shaft (163c) is provided as a circle with an outer diameter corresponding to the inner diameter of the residual pressure relief ring (165). At this time, as illustrated in (a) of Fig. 5, the residual pressure relief ring (165) is coupled to the guide shaft (163c) in an initial state without elastic deformation.

[0078] As illustrated in (b) of Fig. 6, the rear cross-sectional shape of the guide shaft (163c) is provided in the form of horns protruding on both sides by expansion wings (163d). As the width and thickness of the expansion wings (163d) gradually increase toward the rear of the guide shaft (163c), the degree of elastic deformation of the pressure relief ring (165) coupled to the outer circumferential surface of the guide shaft (163c) increases. As a result, as illustrated in (b) of Fig. 5, the shape of the pressure relief ring (165) is elastically deformed to correspond to the shape of the guide shaft (163c).

[0079]

[0080] The residual pressure removal ring (165) is coupled to the guide shaft (163c) of a pair of plunger bodies (161) and moves forward and backward along the guide shaft (163c) in conjunction with the forward and backward movement of the plunger bodies (161) according to the pressure applied thereto, and is elastically deformed, and the plunger bodies (161) move backward, thereby removing the residual pressure inside the dye cylinder (111) and the oxidizer cylinder (113).

[0081] The residual pressure removal ring (165) is provided in the form of an elastic ring as illustrated in Fig. 3. The residual pressure removal ring (165) is provided in the form of a ring having a thickness corresponding to the front of the guide shaft (163c) and the inner diameter of the dye cylinder (111) and the oxidizer cylinder (113) in the initial state as illustrated in (a) of Fig. 5.

[0082] As shown in (b) of FIG. 5 and (a) of FIG. 8, when the plunger body (161) is pressurized by the user, the plunger body (161) moves forward along the inner diameter of the dye cylinder (111) and the oxidizer cylinder (113), and the dye (A) and the oxidizer (B) are discharged through the mixing tip outer case (140).

[0083] At this time, the residual pressure removal ring (165) is pushed to the rear of the guide shaft (163c) by the moving pressure of the plunger body (161) and the frictional force between the inner wall of the dye cylinder (111) and the oxidizer cylinder (113), and moves forward together with the plunger body (161) while in contact with the front pressure plate (163a), thereby causing the dye and oxidizer to be discharged.

[0084] When the difference in width between the pressure relief ring (165) and the expansion wings (163d) formed on both sides of the guide shaft (163c) is large when the pressure relief ring (165) moves rearward, the rearward movement amount of the areas on both sides of the pressure relief ring (165) that surround the expansion wings (163d) is not large, and only the pressure relief ring (165) in the area where the expansion wings (163d) are not formed is pushed rearward and moved. In other words, the rearward movement amount of the pressure relief ring (165) in the remaining area becomes greater than the rearward movement amount of the area of ​​the pressure relief ring (165) that surrounds the expansion wings (163d), which further increases the deformation amount of the pressure relief ring (165).

[0085] Accordingly, the residual pressure removal ring (165) is stretched as shown in (b) of FIG. 5, becomes thinner, and is elastically deformed into a wave shape, and is maintained in a state of being inserted between the guide shaft (163c), the dye cylinder (111), and the oxidizer cylinder (113).

[0086] In this state, the residual pressure relief ring (165) moves forward together with the plunger body (161) and supports the discharge of the dye (A) and oxidizer (B).

[0087] When the user has completed pressurizing the plunger body (161) to a position where the desired amount of dye (A) and oxidizer (B) is discharged, the user stops pressurizing the pair of plunger bodies (161) through the rear flange (161b). When the user's pressurization of the plunger bodies (161) is released, the residual pressure relief ring (165) that has been elastically deformed at the rear end of the guide shaft (163c) applies elastic force toward the guide shaft (163c) so that it can move forward of the guide shaft (163c) to be compressed to the initial inner diameter.

[0088] Accordingly, as shown in (a) and (b) of FIG. 8, the plunger body (161) moves backward by the elastic force of the residual pressure removal ring (165), and the residual pressure removal ring (165) is positioned in front of the guide shaft (163c).

[0089] In this way, as the plunger (160) moves backward by the length of the guide shaft (163c) due to the elasticity of the residual pressure removal ring (165), the residual pressure applied to the plunger (160) is removed, preventing additional discharge of the chemical solution through the mixing tip outer case (140) and enabling only the exact amount of the dye mixture (A+B) to be discharged.

[0090] Here, as the thickness and width of the expansion wing (163d) of the guide shaft (163c) increase, the degree to which the residual pressure removal ring (165) is elastically deformed increases, and the residual pressure removal effect can also be improved.

[0091]

[0092] Meanwhile, the dyeing machine (100) according to a preferred embodiment of the present invention is provided with a pair of expansion blades on both sides of the guide shaft, but in some cases, three or more expansion blades may be provided along the outer periphery of the guide shaft.

[0093]

[0094] The operation process of the dyeing machine (100) according to the present invention having such a configuration is described with reference to FIGS. 1 to 8.

[0095] When storing the dyeing machine (100), the sealing socket (120) and the socket outer cap (130) are combined and stored in front of the cartridge (110) as shown in Fig. 2. The dyeing machine (100) in which the sealing socket (120) and the socket outer cap (130) are combined is packaged together with the mixing tip outer case (140) and the mixing member (150).

[0096] When the user requires the discharge of dye (A) and oxidizer (B) for hair dyeing, the user separates the socket outer cap (130) with the sealing socket (120) housed inside from the cartridge (110) and attaches the mixing tip outer case (140) with the mixing member (150) attached inside.

[0097] And, when the user presses the rear flange (161b) at the rear of the plunger (160), a pair of plunger bodies (161) advance and the front coupling member (163) pressurizes the dye (A) and the oxidizer (B). As shown in Fig. 7, the dye (A) moves from the dye cylinder (111) to the dye discharge pipe (111a) and moves to the mixing member receiving pipe (143) through the dye transfer pipe (152) and the dye supply hole (152a) of the mixing socket (151).

[0098] The oxidizer (B) moves from the oxidizer cylinder (113) through the oxidizer discharge pipe (113a) and moves to the mixing member receiving pipe (143) through the oxidizer moving pipe (153) and the oxidizer supply hole (153a) of the mixing socket (151).

[0099] The dye (A) and oxidizing agent (B) moved to the mixing member receiving tube (143) move along the mixing element (155) and are mixed with each other. As the mixing member receiving tube (143) moves to the tip, the dye (A) and oxidizing agent (B) are uniformly mixed with each other, and the mixed dye mixture (A+B) is discharged to the outside through the mixture discharge hole (143a) and used for dyeing.

[0100] Meanwhile, when the user presses the plunger (160), the residual pressure relief ring (165) coupled to the guide shaft (163c) moves backward and is elastically deformed as shown in (a) of FIG. 8. When the desired amount of dye mixture (A+B) is discharged, the pressurization of the plunger (160) is stopped. When the pressurization of the plunger (160) is stopped, the elastically deformed residual pressure relief ring (165) applies elastic force to restore to the initial state, and as shown in (b) of FIG. 8, the plunger (160) moves backward, the residual pressure is removed, and only the specified amount of dye mixture (A+B) is discharged without additional discharge.

[0101] Meanwhile, when the desired dye mixture (A+B) is completely discharged, the mixing tip outer case (140) and the mixing member (150) can be separated from the cartridge (110), and the sealing socket (120) and the socket outer cap (130) can be reassembled for storage.

[0102]

[0103] As described above, the dye cartridge assembly according to the present invention stores the dye and the oxidizer in each cartridge, and when in use, mixes them evenly using the mixing tip outer case and the mixing member and discharges them to the outside.

[0104] Accordingly, the conventional process of users squeezing the dye and oxidizer into a container and then mixing them with a brush can be omitted.

[0105] In particular, it has the advantage of being able to discharge only the amount of dye mixture desired by the user by removing the internal residual pressure through the residual pressure removal ring.

[0106]
