Figures 6 and 7 are diagrams for explaining a use example of a personal care device according to an embodiment of the present invention.

Referring to Figures 6 and 7, the user discharges the contents stored in the container body 110 by a simple action of pressing the container body 110, and applies and massages the contents to the skin using the application tip 241. can be performed.

For a more detailed explanation, scalp care using the personal care device 1000 will be described as an example.

First, before the user pressurizes the container body 110, the contents cannot move to the brush unit 240 because the contents opening and closing part 231-2 of the check valve 230 is in close contact with the sealing part 224. When the user presses the container body 110, the discharge pressure of the contents increases and pressurizes the contents opening and closing part 231-2, and accordingly, the contents opening and closing part 231-2 is deformed downward and closes the sealing part 224. A space is created between the contents opening and closing part 231-2. Accordingly, the content moves into the space between the sealing portion 224 and the content opening/closing portion 231-2, and the content passes through the content distribution groove 228 and is discharged to the outside through the content discharge passage 242. At this time, since the content discharge path 242 is formed to penetrate the application tip 241, the user moves the personal care device 1000 with the application tip 241 in contact with the scalp to apply the content to the scalp. At the same time, a massage on the scalp can be performed. At this time, since the brush portion 240 is made of a soft material, the application tip 241 is deformed in a state in contact with the scalp and can massage the scalp, through which the user can feel a softer touch. At the same time, a large area can be massaged, and even if a strong external force is unintentionally applied to the personal care device 1000 during scalp massage, the scalp can be prevented from being damaged by the application tip 241.

Thereafter, when the pressure on the container body 110 is released, air is sucked in through the content discharge passage 242 because the pressure inside the container body 110 is lower than the outside. As the sucked air moves through the air moving part 232-3 and into the air moving hole 231-1, the air opening and closing part 232-2 is deformed and spaced apart from the air inlet hole 222. Therefore, the air moves into the space separated between the air opening and closing part 232-2 and the air inlet hole 222 and is sucked into the container body 110, and then the air opening and closing part 232-2 is restored and the air flows in. It comes into close contact with the ball 222 again, preventing contents and air from moving through the air inlet hole 222.

After use, the container body 110 can be stored coupled to the top of the care unit 200 and the care unit 200 placed on the floor. Since the contents are always facing the care unit 200 even during storage, the contents can be easily discharged even with a small external force.

Here, the personal care device 1000 has been described as an example of managing the scalp, but it is not limited thereto, and can manage the skin of various body parts, such as the face, according to embodiments of the present invention.
