Description

  The present invention relates to an ultrasonic cosmetic device capable of performing skin beauty by ultrasonic vibration.

  This type of ultrasonic cosmetic device is configured such that an ultrasonic head is provided on the lower surface of the distal end portion of the body case, and the ultrasonic head can be vibrated ultrasonically. And this ultrasonic cosmetics device treats skin (especially facial skin) by generating a massage effect by applying an ultrasonic head that outputs ultrasonic vibrations to the skin. In addition, although many types of this kind of ultrasonic cosmetics are marketed, there exist some which are shown by Unexamined-Japanese-Patent No. 2000-233005 (patent document 1) as a well-known literature.

  And in the conventional ultrasonic cosmetic device, the skin contact surface of the ultrasonic head is almost circular with a diameter of about 30 to 40 mm. Therefore, the outer periphery of the skin contact surface of the ultrasonic head has an arc shape with a gentle curvature over the entire circumference. Further, the ultrasonic head is attached in a state in which the posture cannot be changed at a predetermined position (the lower surface of the distal end portion) of the container case.

  By the way, the face to be treated includes a relatively wide area such as a cheek or a forehead, and a relatively narrow area such as a corner of an eye, an upper eyelid, a nose (dent), or a hairline.

Japanese Patent Laid-Open No. 2000-23305

  However, in the conventional ultrasonic cosmetic device, the outer circumference of the skin contact surface of the ultrasonic head is an arc having a gentle curvature over the entire circumference, so a relatively large area (cheek or forehead) of the facial skin. Although treatment can be performed without hindrance, it is difficult to accurately apply the ultrasonic head to narrow areas of the face (such as the corners of the eyes, upper eyelids, dents around the nose and hairline). That is, for example, when treating a narrow (small range) part such as the corner of the eye or upper eyelid, the part near the front end of the ultrasonic head is generally used, but the outer circumference of the skin contact surface of the ultrasonic head has a curvature. If it is a loose arc shape, the ultrasonic head may get in the way of contact with excess parts of the facial skin, or it may be difficult to apply the ultrasonic head well at the recessed part (eg around the nose) .

  Note that if the skin contact surface of the ultrasonic head has a small area (for example, a circle having a diameter of about 10 mm), it can be accurately applied to a narrow part of the face skin. The head is inefficient when treating large areas such as cheeks and foreheads.

  In view of the above-described problems of the conventional ultrasonic cosmetic device (ultrasonic head), the present invention provides an ultrasonic cosmetic device that can treat a wide area portion and a narrow portion of the facial skin with a single device. The purpose is to provide.

  The present invention has the following configuration as means for solving the above problems.

  The present invention is an ultrasonic cosmetic device in which an ultrasonic head is provided on the lower surface of the front end portion of the body case, and can treat skin (mainly facial skin) by ultrasonic vibration output from the ultrasonic head. Is.

  The body case should be of a size that can be used by hand (handy type).

  The ultrasonic head is attached so as to protrude downward from the lower surface of the front end portion of the container case. An ultrasonic wave generating element is provided in the ultrasonic head, and the ultrasonic wave generating element vibrates ultrasonically to vibrate the entire ultrasonic head.

  The skin contact surface of the ultrasonic head (the lower surface of the ultrasonic head) is formed in a substantially oval shape having a wide arc portion on one end side and a narrow pointed head on the opposite side. The outer circumference of the wide arc portion is an arc surface having a relatively loose curvature with a radius of about 15 to 20 mm (diameter 30 to 40 mm), for example, and the outer circumference of the narrow apex portion has a radius of about 5 mm (diameter 10 mm), for example. The arc surface has a relatively steep curvature.

  The ultrasonic head has an angle of 180 ° between the posture in which the wide circular arc portion is located on the front side of the body case and the posture in which the narrow pointed head is located on the front side of the body case. It is installed so that it can be rotated left and right within the range of. The ultrasonic head can be held by a stopper or the like in a posture in which the wide arc portion is located on the front side of the body case and a posture in which the narrow-width cusp is located on the front side of the body case. Good.

  The ultrasonic cosmetic device of the present invention can perform a treatment by a massage action by operating an ultrasonic head (ultrasonic vibration) and applying the skin contact surface of the ultrasonic head to the skin (face skin). At that time, if the part to be treated is a large area such as a cheek or forehead, and the posture of the ultrasonic head with the wide arc part facing forward is the same as in the conventional case, the large area part can be efficiently processed simultaneously. You can treat. On the other hand, if the part to be treated is a narrow part such as the corner of the eye or the upper eyelid, if the narrow head of the ultrasonic head is pointed forward, only the vicinity of the narrow head is in contact with the treatment part. (The ultrasonic head does not touch the excess skin surface).

  As described above, in the ultrasonic cosmetic device of the present invention, the skin contact surface of the ultrasonic head has the wide arc portion and the narrow apex head, and the ultrasonic head is divided into the wide arc portion and the narrow apex portion. Since the head can be rotated to the left and right until the posture is directed forward, the wide arc portion can be directed forward during the treatment of a large area (the wide area can be treated efficiently), and the narrow part During treatment, the head with the narrow head pointed forward can be performed (the skin contact surface of the ultrasonic head does not hit the extra skin surface).

  Therefore, it is possible to efficiently treat the entire area of the facial skin with a single ultrasonic cosmetic device, and to treat narrow areas such as the corners of the eyes and upper eyelids with a narrow cusp. There is.

  Hereinafter, an embodiment of the present application will be described with reference to FIGS. 1 to 5. The ultrasonic cosmetic device of this embodiment is configured by attaching an ultrasonic head 2 to the lower surface of the front end portion of the body case 1. The ultrasonic cosmetic device of this embodiment also has an ion introduction function and a cleansing function. The iontophoresis function is to allow the active ingredient (ionized) in the skin lotion to penetrate into the skin, and the cleansing function is to remove dirt in the pores of the skin. The function will be described later.

  The container case 1 is made of plastic and has a size that can be used by hand (for example, a length of 170 to 180 mm, a width of 40 to 50 mm, and a thickness of about 35 to 40 mm).

  On the left and right side surfaces of the container case 1 are provided electrode plates 11, 11 that serve as electrical contacts during ion introduction or cleansing. Each of the electrode plates 11 and 11 is in a position that comes into contact with the hand when the body portion of the body case 1 is gripped by the hand.

  The ultrasonic head 2 is attached so as to protrude downward from the lower surface of the front end portion of the container case 1. In addition, the lower surface of the ultrasonic head 2 becomes the skin contact surface 20. For the skin contact surface 20, a metal plate having electrical conductivity is used. This skin contact surface (metal plate) 20 serves as one electrode at the time of ion introduction or cleansing. The skin contact surface of the ultrasonic head 2 is touched by touching the electrode plates 11 and 11 on the side of the container case 1 described above. By pressing the surface 20 against the skin, electricity is passed through the human body.

  An ultrasonic generation element 3 is provided in the ultrasonic head 2, and the ultrasonic head 2 can be vibrated ultrasonically by energizing the ultrasonic generation element 3. Note that the ultrasonic frequency output from the ultrasonic head 2 can be adjusted stepwise (for example, three levels of strong, medium, and weak) with 3 MHz as the upper limit.

  The skin contact surface 20 of the ultrasonic head 2 is formed in a substantially oval shape having a wide arc portion 21 on one end side and a narrow pointed head portion 22 on the opposite side. The outer circumference of the wide arc portion 21 is an arc surface having a relatively loose curvature with a radius of about 15 to 20 mm (diameter 30 to 40 mm), and the outer circumference of the narrow apex 22 has a radius of about 5 mm (diameter 10 mm). The arc surface has a sharp curvature.

  A ring 23 for protecting the ultrasonic head 2 is provided on the outer peripheral portion of the ultrasonic head 2. The ring 2 is made of cotton so that it does not deteriorate when it comes into contact with the skin. The lower surface of the ring 23 is located above the skin contact surface 20 of the ultrasonic head 2, and even if the skin contact surface 20 of the ultrasonic head contacts the skin during treatment, the ring 23 contacts the skin. It is supposed not to. The ring 23 can be freely replaced, and can be used without being attached.

  The ultrasonic head 2 has a posture in which the wide circular arc portion 21 is positioned on the front side of the body case 1 with respect to the body case 1 (state shown in FIG. 5) and a narrow pointed head 22 of the body case 1. It is attached so that it can be rotated left and right within a range of an angle of 180 ° with respect to the posture positioned on the front side (state shown in FIGS. 1 to 4). That is, as shown in FIG. 4, the ultrasonic head 2 is rotatably supported by a bearing portion 24 having an axis near the center of the wide arc portion 21 on the lower surface of the front end portion of the container case 1. The ultrasonic head 2 can be picked with a finger and rotated left and right. The ultrasonic head 2 has a posture in which the wide circular arc portion 21 is located on the front side of the body case (FIG. 4) and a posture in which the narrow-width sharp head 22 is located on the front side of the body case (FIGS. 1 to 4). ) And can be held by a stopper.

  As shown in FIGS. 2 and 4, various switches and display lamps (LEDs) are provided on the upper surface of the container case 1. Reference numeral 12 denotes a select switch. The select switch 12 ultrasonically vibrates the ultrasonic head 2 or changes the polarity of the skin contact surface 20 of the ultrasonic head 2 to “+” at the time of ion introduction (or cleansing). You can choose to do or "-". Reference numeral 13 denotes a level switch that can adjust the frequency of ultrasonic vibration and the voltage at the time of ion introduction (or cleansing) in three stages. Reference numeral 14 denotes a switch for skin check.

  A battery 4 is accommodated in the container case 1. A terminal 5 for connecting to a battery charger is provided on the front end surface of the case 1. Further, a terminal 6 for connecting an AC adapter is provided on the rear end surface of the container case 1.

  In the ultrasonic cosmetic device of this embodiment, when the ultrasonic function is selected with the select switch 12 and the ultrasonic generator 3 is energized, the entire ultrasonic head 2 generates ultrasonic vibrations. Then, by applying the skin contact surface 20 of the ultrasonic head 2 to the skin (face skin), a treatment by a massage action can be performed.

  At that time, when treating a narrow part such as the corner of the eye or the upper eyelid, as shown in FIG. 3, the narrow head portion 22 of the ultrasonic head 2 is oriented forward. Then, only the vicinity of the narrow pointed head 22 can be accurately brought into contact with the narrow part to be treated, and the skin contact surface 20 of the ultrasonic head 2 does not need to be brought into contact with the excess part of the skin. Further, in the case where the part to be treated is a wide area such as a cheek or forehead, the ultrasonic head 2 is rotated by an angle of 180 ° from the state of FIG. 3 as shown in FIG. With the posture facing forward. In this case, since the front side of the skin contact surface 20 of the ultrasonic head 2 has a wide width (wide arc portion 21), a skin surface with a wide area can be treated efficiently.

  In this way, with this ultrasonic cosmetic device, a single device is suitable for a treatment for a narrow part (a posture in which the narrow-pointed head 22 shown in FIG. 3 faces forward) and a treatment for a wide area part. There are two ways to use the posture (the posture in which the wide arc portion 21 shown in FIG. 5 faces forward). Further, in a posture in which the narrow-width cusp 22 is directed forward, the skin contact surface 20 can be brought into contact with only a narrow range of the narrow portion (excessive skin surface does not contact the ultrasonic head).

  Ionization of the lotion is performed as follows. In addition, the active ingredient in the lotion is classified into + ion and-ion (generally + ion is more common). Select whether or not. Then, a lotion is applied to the skin surface to be treated, and the body portion of the container case 1 is gripped by hand to bring the skin contact surface 20 of the ultrasonic head 2 into contact with the skin surface to which the lotion is attached. Then, the electrode plate 11 of the body case 1 and the skin contact surface (to be an electrode plate) 20 of the ultrasonic head 2 are energized through the human body, and the electrode plate of the skin contact surface 20 is designated as the + pole or − It becomes a pole, and the ionic component having the same polarity as the skin contact surface 20 in the skin lotion can be electrically permeated into the skin.

  In order to remove (cleanse) dirt in the skin pores, the following procedure is performed. The dirt in the skin pores is + ions. When the polarity of the skin contact surface 20 of the ultrasonic head 2 is set to the negative polarity, the dirt in the pores is brought into contact with the skin of the ultrasonic head 2 by the electric suction action. Suctioned to the surface 20 side.

  Thus, the ultrasonic cosmetic device of this embodiment has an iontophoresis function and a cleansing function in addition to the massage function by the ultrasonic head 2, and a multi-functional usage form can be selected with one piece of equipment.
