Description

Skin cleansing device {Skin cleansing device}

The present invention relates to a skin cleansing device, and more particularly, to a skin cleansing device that is naturally and gently in contact with the skin and has an excellent feeling of use.

Skin care is an act of applying cosmetics or cleansing products to the skin or removing foreign substances from the skin to clean and beautifully manage the skin, and facial skin care is particularly important.

In recent years, air pollution by fine dust has increased, which not only harms personal hygiene and health, but also undesirably affects the management of facial skin exposed to the outside. For example, when fine dust with a small particle size adheres to the skin, the fine dust and various contaminants on the skin are combined and are not easily removed. can lower In order to protect the skin from fine dust along with skin damage caused by ultraviolet rays, effective skin cleansing is important. That is, there is a need to more effectively and efficiently clean various contaminants including fine dust, rather than simply wiping off visible cosmetics or contaminants.

Recently, a method of uniformly applying a cleaning product to the skin or cleaning the skin using a body cleansing device having a brush that rotates or vibrates has been used. For example, Korean Patent Publication No. 10-2017-0099518 discloses a skin cleansing device that cleans or massages the skin by rotating a contact unit equipped with a brush that contacts the skin. In addition, Korean Patent Registration No. 10-2324257 discloses a body cleansing device that supplies ultrasonic vibration to a user by vibrating a brush unit using a vibration motor or vibrating an ultrasonic head using an ultrasonic vibrator. However, since such a conventional body cleansing device uses a simple rotary motion or a vibration motion by a vibration motor, the body cleansing effect is low, and in particular, when applied to the facial skin, there is a disadvantage in that the feeling of use is not good.

Facial skin is a very sensitive and vulnerable part of the human body, and should not be physically stimulated when washing or washing. In order not to apply excessive stimulation to the skin while effectively washing the face, it can be said that the hand motion of the traditional hand washing method or the facial massage exercise using the hand is suitable. Therefore, there is an increasing need for a skin cleansing device that not only efficiently cleans the skin by rubbing against the skin more naturally and softly, but also has an excellent feeling of use, instead of the conventional simple rotational motion or vibrational motion.

Preferably, the housing 10, the vibration cleansing unit 20, and the flexible connection unit 30 are integrally connected to have a waterproof function.

5a and 5b are diagrams for explaining the internal structure and operating state of the skin cleansing device according to an embodiment of the present invention. 3 to 5, the driving motor 40, the driving cam 50 and the vibration driving unit 60 inside the housing 10, the vibration cleansing unit 20 and the flexible connection unit 30 integrally connected thereto is mounted When the driving cam 50 is rotated by the driving of the driving motor 40, the vibration driving unit 60 is driven by vibration.

As best shown in FIGS. 5A and 5B , the driving cam 50 has a cylindrical shape, and is positioned in an up-and-down direction along the circumference of the cylindrical shape (h, hereinafter, simply referred to as 'height' as necessary). A guide groove (56, guide) in which is continuously changed is formed. Since the height of the guide groove 56 formed around the drive cam 50 continuously changes, when the drive cam 50 rotates along the cylindrical axis, the drive cam 50 is positioned at a predetermined position (for example, , 0 degree and 180 degree directions), the height of the guide groove 56 continuously changes. The guide groove 56 preferably has a shape of a closed curve so that the height h increases along the circumference of the driving cam 50 and then decreases and returns to the original position. For example, as shown in FIG. 5, the height h of the guide groove 56 increases up to 90 degrees along the circumference of the drive cam 50, decreases up to 180 degrees, and again up to 270 degrees, as shown in FIG. It may increase, decrease up to 360 degrees, rotate once around the driving cam 50, and then return to its original position.

It is desirable to be The lever arm guide grooves 70a and 70b guide the sliding movement of the lever arms 68a and 68b in the vertical direction and prevent the lever arms 68a and 68b from rotating together with the drive cam 50. That is, the lever arm guide grooves 70a and 70b guide the vertical motion of the lever arms 68a and 68b, thereby improving the degree of completion of driving the lever arms 68a and 68b and making the lever arms 68a and 68b more stable. can drive it.

The upper ends of the diaphragms 64a and 64b support one end (eg, both ends) of the diaphragm 22, preferably fixedly supported (see FIG. 3A). For example, the upper ends of the diaphragms 64a and 64b and the lower surface of the diaphragm 22 may be fixedly coupled by a fitting method or the like. Therefore, according to the vibration of the diaphragms 64a and 64b, both ends of the diaphragm 22 and the cleansing pad 24 located on the left and right with respect to the fixing plate 62 are repeatedly folded and unfolded to vibrate. do.

According to the skin cleansing device according to the present invention, by rotating the driving cam 50, similar to the movement of the wings of a butterfly, both ends of the cleansing pad 24 are stable, soft and naturally vibrate in the vertical direction. Therefore, according to the present invention, by embodying a motion of pressing or rubbing the skin with a fingertip, rather than a simple rotation or vibration motion of a conventional electric cleanser, it has a cleansing effect and an effect of gently acupressure on the skin. Continuous and gentle pressure by the skin cleansing device of the present invention gives reversible stimulation without damage to the skin, which can promote skin metabolism by helping blood circulation of the skin together with effective facial cleansing. In addition, the body of the small cleansing device, which is designed in a structure wrapped entirely by hand, is effective in cleansing (face washing) and massage because it is easy to naturally add and subtract power to the physical movement of the cleansing pad 24.
