JPH02279107A - Method and device for ultrasonic depilation - Google Patents

Abstract

PURPOSE:To execute a smooth depilation without allowing a man to feel a pain so much by drawing out a hair to be depilated, while giving ultrasonic energy thereto. CONSTITUTION:When an oscillation output is inputted to an output transformer 3 from an oscillation circuit 1, and also, supplied to a vibrator 6 of a pick adaptor 4 for depilation, one pick piece 9 generates an ultrasonic vibration, and by inserting and holding a hair with both the pick pieces 9, 9', the ultrasonic vibration generated in the pick piece 9 is transferred to the hair. In such a way, while allowing the ultrasonic vibration to work on the root of the hair to be drawn out, the air is drawn out gradually by its pick and when tensile force, for instance, of 50 to 100g per piece is allowed to work, bonding strength (ultrasonic medium tissue) of the root of hair and the skin is cut apart, and the depilation can be executed smoothly without allowing a man to feel a pain so much.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a novel hair removal method and device using ultrasonic energy.

[Prior Art] Conventional hair removal methods used, for example, for the purpose of body beauty include the following hair removal methods.

89 Hair removal method using a tweezer This hair removal method using a tweezer is a commonly used method because it is easy to perform, but hair removal using a tweezer does not involve forcefully pulling out hair using instruments such as tweezers. Therefore, the stimulation during hair removal is so strong that it is impossible to remove many hairs at once, and there are also problems in that care must be taken to prevent bacterial infection.

b8 Hair removal method by applying hair removal wax This method involves melting a designated hair removal wax and applying it to the skin.
After the hair removal wax dries, the film-like wax sheet is peeled off from the skin and the hairs attached to the wax sheet are plucked out, but this hair removal method is extremely painful as it removes many hairs at once. It may not be suitable for some areas of hair removal.

C0 Chemical hair removal method This method involves applying a hair removal cream, but most of these hair removal creams increase the moisture content of the hair and reduce the elasticity of the hair, making it easier to tear the hair. Therefore, with this method, many of the hairs break off at the skin surface, making it difficult to pull them out from the hair roots.

d. Hair removal method using electrolysis This is a method in which a direct current is passed through the dermal papilla to destroy the dermal papilla, so that the hair that has come out of the hair follicle cannot be permanently regenerated. This hair removal requires high labor costs as it requires a specialist.
Furthermore, there is the inconvenience that hair removal cannot be done easily at home.

e. High-frequency current hair removal method This is said to heat-treat the dermal papilla using high-frequency waves to cause it to atrophy, thereby painlessly removing hair. In this case, it takes several tens of seconds to pull out one hair. Since it takes more than a minute, hair removal takes a long time, and furthermore, it is difficult to time the hair removal. Further, during the hair removal process, the hair must be cut to an appropriate length, so there is a problem that the hair removal process is time-consuming.

[Means for Solving the Problems] The present invention has been made by focusing on the problems of the conventional hair removal method, and it reduces irritation during hair removal and furthermore, allows hair removal to be performed extremely easily at home. This is the development of a hair removal method and device that can do this. Furthermore, to describe the present invention more specifically, ultrasonic energy (imaging) is applied to the hair root to be removed, the ultrasonic energy is used to divide the hair root and the skin tissue, and when the hair root is separated, the hair is removed. The present invention provides a new hair removal method that can remove hair without causing much pain.

[Example] Embodiments of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes an ultrasonic oscillation circuit, and by applying the power obtained from the power supply circuit 2 to this oscillation circuit 1, the excavation output from the excavation circuit 1 is supplied to the output transformer 3, and further, the output transformer 3 Desired output e.g. 4-20w
is made possible and supplied to the hair removal pick adapter 4. The structure of this hair removal pick adapter 4 is as shown in FIG. 2, and 5 is a cylindrical case, and a vibrator 6 is placed in the case 5 at a position that does not interfere with its vibration. It is held via an attached support member 7. Further, one pick piece 9 is fixed to the tip of the vibrator 6 via a horn 8. The other pick piece 9° corresponding to the one pick piece 9 is fixed integrally with the cylindrical case 5.

Therefore, by supplying all the signals from the excavation circuit 1 to the vibrator 6 via the output lance 3, one pick piece 9 causes ultrasonic vibration, and both pick pieces 9.9 degrees move the hair. By pinching, the ultrasonic vibration generated in the pick piece 9 is transmitted to the hair.

In this way, while applying ultrasonic vibration to the root of the hair to be pulled out, the hair is gradually pulled out using the pick. The bonding force between the hair root and the skin (ultrasonic medium tissue) is divided, allowing for smooth hair removal without much pain.

According to experiments conducted by the present inventor, the effective frequency i# of ultrasonic energy to be applied to the hair roots to be removed is 20 to 20.
60 k) Iz was valid.

In other words, the size of the hair and the depth of the hair root vary widely.

Therefore, relatively thick pubic hair, leg hair, armpit hair, etc., as well as relatively thin hair growing on the arms, etc., are removed by applying the ultrasonic energy described above so that the pulling tension is approximately constant. is the output frequency of the oscillation circuit 10
As a result of hair removal while adjusting the frequency in the range of -100 kHz, when the output frequency was 20 to 60 kl (z), hair removal was achieved relatively smoothly and with less pain.

[Effects of the Invention] As described above, the present invention is an ultrasonic hair removal method in which the hair to be removed is pulled out while applying ultrasonic energy. As a result, hair removal becomes smooth and painless. Further, the hair removal device of the present invention can be made lightweight and compact, and can be easily handled at home, so it has excellent practicality.
