Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ultrasonic skin beautifying apparatus in which a recess is formed in a head of a probe that vibrates ultrasonically, this is covered with a mesh plate having innumerable small holes, and a liquid is guided to the back side to eject mist.
[0002]
[Problems to be solved by the invention]
Ultrasound generates vibration waves with strong energy and has the effects of crushing the cells, peeling off the surface layer, washing, heat generation, etc. When this vibration wave acts on the skin, it sterilizes the skin surface layer, Removes stratum corneum, raises acne, pore oil, dirt, makeup residue, etc., promotes blood circulation on the skin surface and activates tissue, relieves muscle tension and removes spots, wrinkles, tarmi, etc. Has a beautiful skin effect.
[0003]
However, the ultrasonic wave is greatly attenuated in the air, and even if the ultrasonic vibrating body is brought into direct contact with the skin, the air in the way interferes and the energy is not efficiently transmitted to the skin.
For this reason, a medium such as cream or gel is applied to the contact surface between the ultrasonic vibrator and the skin to increase the propagation efficiency of the ultrasonic wave.
[0004]
On the other hand, when water or lotion is misted with ultrasonic waves and sprayed onto the skin, fine water particles penetrate into the deep part of the skin and moisturize the skin.
Skin that is moistened with water or lotion efficiently transmits ultrasonic vibration waves, and the water particles wash away the fat and dirt that floated on the skin surface, while the active ingredient penetrates and nourishes throughout the skin. It has the effect of refreshing and rejuvenating the skin.
Thus, the ultrasonic mist has the effect of moisturizing the skin to increase the propagation efficiency of the ultrasonic wave, washing the dirt, and giving nutrition to the skin.
[0005]
The ultrasonic mist is generated by guiding a liquid to a mesh plate that vibrates ultrasonically.
However, if the fine vibration of the ultrasonic wave is transmitted to the mesh plate as it is, the vibration power for decomposing the liquid into fine particles is insufficient, so that a sufficient mist cannot actually be generated.
[0006]
Therefore, the present invention has been made for the purpose of increasing the vibration power of the mesh plate and generating sufficient mist.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0010]
1 and 2 are a front view and a side view, partly cut away, of an ultrasonic skin beautifying apparatus embodying the present invention.
In the ultrasonic skin beautifying apparatus, a cylindrical head 2 is provided on the front surface of a probe 1 and an ultrasonic vibrator 3 made of piezoelectric ceramics is fixed inside the head.
[0011]
The head 2 has a hole 4 in the head surface, and a mesh plug 5 is detachably fitted in the hole to close the recess 4, thereby forming a space 6 on the back side of the mesh plug 5.
A connection hole 7 communicating with the space 6 is opened on the outer periphery of the head 2, and an outlet 9 of the container 8 is detachably inserted into the connection hole 7 to connect the space 6 and the container 8.
By providing the container 8, a certain amount of liquid can be stored in the container 8, so that the trouble of injecting the liquid into the connecting hole 7 each time can be saved.
Also, various types of liquid can be exchanged together with the container 8 to generate various types of mist.
When replacing the container 8, the mesh plug 5, the space 6 and the connecting hole 7 are thoroughly washed so that different types of liquids are not mixed.
[0012]
3 and 4 are a front view and a longitudinal sectional view of the mesh plug 5. FIG.
The mesh plug 5 projects a minute support base 52 on the inner wall at the bottom of the outer frame 51 as a cylindrical mesh plate support with one side cut out, and has a mesh having the same diameter as the inner periphery of the outer frame 51. One end of the plate 53 is fixed and the mesh plate 53 is cantilevered.
The height of the support base 52 is about 0.2 mm from the bottom, and when the mesh plug 5 is fitted into the recess 4, the cutout portion faces the connection hole 7 so that the outer frame 51 does not get in the way. 7 communicates with the space 6.
[0013]
The outer frame 51 is formed of an elastic material such as a resin, and the notch portion is enlarged or reduced to widen or narrow the cylinder diameter.
Thus, when fitting the mesh plug 5 in the recess 4, and inserted into the recess 4 by narrowing the cylindrical diameter of the outer frame 51, to press the inner wall of the recess 4 by the spring force of the outer frame 51 extends Mesh The stopper 5 is fixed in the recess 4.
Further, a circumferential groove 54 as an engaging portion for extraction is formed along the inner periphery of the outer frame 51, and the mesh plug 5 is pulled out from the recess 4 by hooking a claw of an extraction tool into the circumferential groove 54. .
[0014]
As shown in FIG. 5, the container 8 may be inserted into the connecting hole 7 with a liquid pipe 10 attached to the outlet 9. Thereby, it is possible to replace the container 8 together with the liquid pipe 10 so that the connection hole 7 is not soiled.
The liquid tube 10 is filled with a water retention material 11 such as a sponge so that the liquid in the container 8 does not flow out at once.
Further, the stopper 12 is fitted into the supply hole of the container 8, and when empty, the stopper 12 is removed and the liquid is supplied.
The stopper 12 is provided with a small-diameter air hole 13 and connected to the outside to help the liquid in the container 8 flow out into the space 6.
[0015]
The head 2 is made of a flexible and elastic thin stainless steel plate, or a metal such as hard aluminum, duralumin, or thin copper plate, and is subjected to a surface treatment such as hard chrome plating.
[0016]
The mesh plate 53 has innumerable small holes and has a diameter of 50 to 100 μm, and a large number of mesh plates 53 are distributed at high density throughout the mesh plate 53.
The small hole has a tapered shape in which the diameter on the outlet side is narrower than the inlet side through which the liquid passes to facilitate the ejection of mist.
Also, if the small holes in the mesh plate 53 are too large, the liquid with low viscosity is liable to leak from the mesh plate 53 when the switch is turned off, and if it is too small, the liquid with high viscosity will cause problems such as difficulty in making mist. The mesh plate 53 is replaced with a small hole having a different diameter depending on the viscosity of the small hole.
The mesh plate 53 having innumerable small holes can be made by processing a thin metal plate by etching or electroforming.
[0017]
In addition to this, the probe 1 is provided with a power switch 14.
[0018]
The ultrasonic skin beautifying apparatus embodying the present invention is configured as described above, and the container 8 is connected to the head 2 of the probe 1 to inject the liquid in the container 8 into the connecting hole 7 and the space 6.
At this time, the liquid in the connection hole 7 and the space 6 tends to leak out through the mesh plate 53. However, in a stationary state where the power switch 14 is off, the connection hole 7 and the space 6 are narrow and the total amount of liquid is small. In addition, since the liquid is restrained by the surface tension of the liquid, the liquid stops in the connection hole 7 and the space 6 and does not leak from the mesh plate 53.
In this state, when the power switch 14 is turned on and a vibration voltage is applied to the ultrasonic transducer 3, the head 2 undergoes bending deformation and vibrates with a minute amplitude, and this ultrasonic vibration wave is generated in the connection hole 7 and the space 6. It acts on the filled liquid and pushes the liquid out of the mesh plate 53.
At the same time, the vibration is transmitted to the mesh plate 53 whose one end is cantilevered and supported by the support base 52 of the outer frame 51, and the vibration of the mesh plate 53 is amplified around the support base 52, so that the open end portion vibrates greatly.
Supporting the mesh plate 53 in a cantilevered manner has an effect of enhancing the vibration of the mesh plate 53 and amplifying and transmitting ultrasonic vibration waves.
As described above, sufficient vibration power is transmitted to the liquid passing through the mesh plate 53, so that the liquid is decomposed into fine particles and ejected from the surface of the mesh plate 53 in the form of a mist.
[0019]
【The invention's effect】
As described above, ultrasonic skin beautifying apparatus of the present invention, sufficient vibration power to the vibration of the ultrasonic vibration to the mesh plate for atomizing the amplified liquid is transmitted by cantilevered mesh plate Therefore, it becomes possible to solve the power shortage and generate sufficient mist.
Further, when the liquid storage part is made detachable, various types of liquid can be exchanged together with the container to generate various types of mist. Furthermore, if the mesh plate is also replaced with one having a small hole diameter according to the viscosity of the liquid, the mist can be appropriately produced.
