Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 to 4 , the hair dyeing machine according to the embodiment of the present invention includes a discharge unit 100 , a case unit 200 , and a dye supply unit 300 .

Hereinafter, specific contents of the present invention will be described for each configuration.

The discharge unit 100 is configured to provide dye between the user's hair, and includes a brush 110 and a brush rubber 130 .

The brush 110 has a predetermined length so that it can enter between the user's hair, and is connected to an outlet 111 in which a discharge hole 111a, which is a passage through which the dye is discharged, is formed in the inner center, and one end of the discharge port 111 . However, it consists of a brush body 112 provided in a shape corresponding to the vertical cross-sectional shape of the brush receiving part 235 so as to be slide-inserted into the brush receiving part 235 to be described later.

The discharge ports 111 are preferably arranged in two rows of a zigzag shape so that the dye can be evenly supplied between the user's hair.

A seating groove 113 into which the brush rubber 130 is inserted and supported is formed at one side of the brush body 112 .

In addition, a flow path part 114 communicating with one end of the discharge port 111 inside the seating groove 113 of the brush body 112 and forming a predetermined space inside the brush body 112 is provided.

The flow path part 114 is formed to extend in the longitudinal direction of the discharge port 111 as shown in FIG. The guide wall 114b is formed, and the vertical wall 114a and the guide wall 114b form a closed flow path in plan view.

The vertical wall 114a has a structure that is open only in the longitudinal direction of the guide wall 114b in a plan view and the remaining part is a closed structure, and a unit storage unit u in which the dye can be temporarily stored inside the vertical wall 114a. ) is formed.

As shown in (b) of FIG. 4 , the guide walls 114b are provided on the outlet 111 side, respectively, and are formed in two rows, thereby forming a narrow flow path between the guide walls 114b in each row. The narrow passage allows the dye to flow rapidly in the direction of both ends.

And while the dye moves along the flow path, a portion flows into the vertical wall 114a connected to the guide wall 114b.

At this time, since the dye has a certain degree of viscosity, even if the dye moves toward the vertical wall 114a, it is not immediately discharged to the outside through the discharge hole 111a, but is filled in the flow path 114 to a predetermined height, When the dye continues to flow into the flow passage 114 , the pressure increases and is gradually discharged to the outside through the discharge hole 111a of the discharge port 111 .

As described above, in the present invention, since the dye is discharged to the outside in a state in which a certain amount is accommodated in the channel part 114 by providing the flow path part 114, uniform discharge of the hair dye becomes possible.

When the viscosity of the dye is low, the dye discharged from the supply hole 237 is mostly accommodated in the longitudinal center side of the brush 110 and is directed toward both ends. Since the flow does not flow sufficiently, the dye is discharged from the outlet 111 in the center of the brush 110 .

Accordingly, in the present invention, the inner diameter size of each vertical wall 114a may be varied from the longitudinal center of the brush 110 to both ends.

That is, as shown in (b) of FIG. 4, vertical walls from the center to both ends are called vertical walls 114a, vertical walls 114a', and vertical walls 114a'', respectively, and their inner diameters are respectively When a, b, and c are defined, the relationship a < b < c is formed.

Similarly, instead of varying the size of the inner diameter of the vertical wall 114a, the diameter of the discharge hole 111a of the discharge port 111 may be changed.

The brush rubber 130 is inserted into the seating groove 113 of the brush 110 to prevent the dye from leaking to the outside. It has a cross-sectional shape including the protrusion 130a as shown in an enlarged cross-sectional view of "A".
