In addition, the main body 100 may be driven by the battery 120, and the battery 120 may be reusable by charging (see FIGS. 10 and 11). As an example, the main body 100 may be placed on the pedestal portion 300 for storage. In this case, the pedestal portion 300 may have a function capable of charging the battery 120. For example, the pedestal part 300 may serve as a charging function and a placement function capable of converting an external power source (for example: AC 220V) into a DC power source (for example: DC 5V). In addition, the pedestal portion 300 may include a pedestal groove portion 310 for inserting and seating the main body 100.

In this way, the main body 100 may have both the current generation part 160 for applying current to the second transmission part 220 and the vibration part 140 and the ultrasonic oscillation circuit 130 for transmitting ultrasonic vibrations to the first transmission part 210.

In addition, the main body 100 may include a battery 120 that is connected to the ultrasonic oscillation circuit 130 and the current generation part 160.

When the cosmetic device head according to an embodiment of the present invention is used, the degree of freedom of the head can be improved compared to the conventional cosmetic device head using stainless steel (STS) or titanium (Titanium). FIG. 12 is a flowchart for explaining the method of manufacturing the cosmetic device head 200 shown in FIGS. 2 to 9.

Referring to FIG. 12, a manufacturing method according to an embodiment of the present invention may include: as a mixing raw material for manufacturing the first transfer part 210, a colorant powder, a binder powder, and a non-conductive molding raw material are mixed by a blender To prepare the step of mixing raw materials (S100).

The mixed raw material is prepared by mixing the raw material preparation step (S100) to mix the colorant powder, the binder powder, and the non-conductive molding raw material. The component content of the mixed raw material or its weight percentage (wt%) may vary according to the color and material. When the first transmission part 210 is a cosmetic device head such as FIGS. 3 to 9 exposed to the outside, the color of the first transmission part 210 can be adjusted according to the user's preference. For example, the first transfer part 210 may be manufactured in white or black. When white, the non-conductive molding material may be zirconia (ZrO ₂ ). Since the inherent color of zirconia is white, no additional colorant powder may be needed. For example, when the non-conductive molding material is zirconia powder, the white mixed material may be 86.9 wt% of non-conductive molding material and 13.1 wt% of binder powder (502). In addition, when the non-conductive molding raw material is zirconia powder, the black mixed raw material may be 83.9wt% of non-conductive molding raw material and 13.1wt% of binder powder, 3wt% of black pigment (black pigment) that is colorant Powder (501).

In addition, in the mixed raw material preparation step (S100), the additive may further include a functional material that emits infrared rays. In this case, the content of the mixed raw material may be adjusted.

In addition, the mixed raw material can be pulverized by a jet mixer. As a result, the pulverized mixed raw material may have a fine distribution corresponding to 300 to 320 mesh (mesh).

At this time, the 300-320 mesh value of the mixed raw material may be a critical value for manufacturing the optimal first transfer part 210 in the forming step (S300) and the sintering step (S400) of the first transfer part 210 described later. That is, under the fine distribution of the mesh value, it may be difficult to obtain the first transfer part 210 in a semi-finished product state. Under the fine distribution of the mesh value, the molding and sintering quality of the first transfer part 210 It may decrease, so the target value may have a critical meaning.

In addition, the manufacturing method of the present embodiment supplies the mixed raw material to the mold having the outer surface shape of the first transfer part 210 (S200).

The outer surface shape of the first transmission part 210 may be projected to correspond to the inner shape of the mold.

After the mixed raw material supply step (S200), a pressurizing mold is performed to bond the powder particles of the mixed raw material to each other, thereby forming the step of forming the first transfer part (S300).

The step (S300) of molding the first transfer part 210 may be a series of processes for manufacturing the first transfer part 210 by combining the powder particles of the mixed raw materials with each other by pressing a mold.

The step of molding the first transfer part (S300) is a process of preparing the mixed raw material in the form of mixed powder into a semi-finished product form corresponding to the mold. That is, it may be a process in which the powder particles of the mixed raw material are sufficiently combined so as not to hinder the processing of the next process, that is, the step (S400) of sintering the first transfer part 210, to the first transfer part 210 in the form of a semi-finished product Give mechanical strength.

The forming device including the forming frame in the form of a part mold, the hydraulic circuit and the actuator for operating or supporting the forming frame can be collectively referred to as a mold.

The step (S400) of sintering the first transfer part 210 may be a process of heat-treating the first transfer part 210 in the form of a semi-finished product manufactured by the step (S300) of molding the first transfer part 210, thereby mixing the powder particles of the raw materials The chemical bonding between them is based on diffusion, and the mechanical strength and durability required to transmit ultrasonic waves are formed in the first transmission part 210.

After the step of sintering the first transfer part 210 (S400), the step of polishing the first transfer part 210 (S500) is performed.

The corner part of the first transmission part 210 after the step of grinding the first transmission part 210 (S500) can be made into a rounded part of about 0.2 to 0.3R (curvature). Therefore, there is an advantage that even if forces such as ultrasonic vibration based on excitation or impact applied from the outside are transmitted to the first transmission part 210, the corners of the first transmission part 210 and the like can be prevented from being locally damaged.

After the step of grinding the first transfer part 210 (S500), a step of coating at least a part of the outer surface 212 of the first transfer part 210 with a conductive second transfer part is included (S600).

Among them, the coating may include post-processing such as electroplating, coating, and vapor deposition. Therefore, the second transfer part 220 may be formed on the surface of the first transfer part 210 by post-processing such as electroplating, coating, vapor deposition, etc. after the first transfer part 210 is manufactured.

In addition, as shown in FIGS. 3 to 7, a portion of the first transfer portion 210 that is not covered by the second transfer portion 220 (a portion without post-processing) may be masked using a masking tape or a mask jig. In addition, when there is a non-smooth part (in the case of a burr) between the connection part of the first transfer part 210 and the second transfer part 220 after the process, it is also possible to post-process the part where the burr exists by additionally using laser. In this way, the conductive second transmission part 220 that wraps the first transmission part 210 is formed, so that it is possible to radiate ultrasonic waves, high frequencies, galvanic ions, plasma, or to adjust the temperature through the conductive second transmission part 220 Beauty device head.

After the step of coating with the second transfer part (S600), in order to smooth a part of the second transfer part 220 or the first transfer part 210 that is in contact with the user's skin, a secondary grinding process may be additionally included.

Hereinafter, the operation and effects of the cosmetic device head, the cosmetic device, and the method for manufacturing the cosmetic device head as described above will be described.
