Description

Technical Field [0001] The present invention relates to a vibration device having a durability and stability for skin keratinocytes,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vibrating device for a skin exfoliating beauty machine, and more particularly, And a vibrating device of a beauty machine for removing skin exfoliation that can maintain output performance.

When ultrasonic waves come into contact with water, a bubble jet occurs inside the water molecule, and this bubble jet penetrates into the minute stratum corneum to separate the keratin from the transparent layer.

The cosmetic device for exfoliation is a device for generating bubble jet phenomenon by transmitting ultrasonic waves to a blade made of a metal having high elasticity.

Therefore, many attempts have been made about how to effectively transmit ultrasound to the blade, and it is not an exaggeration to say that it is a desire of a beauty machine for skin exfoliation.

Until now, it has been very difficult to solve this problem because it is very difficult for consumers to find out that there are many problems due to the wrapping of the vibrating device completely wrapping the long blade on the top and bottom.

5 (a), the vibrator assembly 3, 3a is disposed on each of the amplifying plates 2, 2a and the amplifying plate 2, As shown in Fig. 5 (b), amplifying plates 2 and 2a of different thicknesses are disposed on both sides of the long blade 1, and the vibrator assembly 3 is attached to the amplifying plate 2a .

Since the blade 1 and the amplifying plates 2 and 2a are adhered to each other with an adhesive agent, the adhesive strength of the adhesive portion is rapidly reduced as the vibrator activity is actively accumulated. As a result, the transmitting power of the ultrasonic wave transmitted from the blade Which is the most common problem.

This is because the continuous vibration stress occurs at 24 ~ 30 KHz, which is the ultrasound band, and the adhesive force between the blade and the amplification plate is rapidly dropped, which makes it difficult to continuously reproduce the bubble jet phenomenon caused by the transmission ultrasonic wave.

The inventor of the present invention completed the present invention after repeating research and experiment for a long time in order to fundamentally solve the above problems.

Korean Patent Publication No. 10-2014-0030929 (Apr. 13, 2014) Korean Patent No. 10-0802187 (Feb. 11, 2008) Korean Patent Publication No. 10-2008-0006875 (2008.01.17.) Korean Patent No. 10-0856345 (Apr. 4, 2008)

According to the apparatus for vibrating an exfoliating hair cosmetic according to the present invention, since the blades are not arranged long between the pair of amplifying plates, and the vibrator assembly is not arranged on the upper and lower sides of the blades, excellent output performance There is an advantage that it can be maintained.

In addition, it is difficult to adhere the blade to the amplification plate due to the surface characteristics of the stainless steel material having a dense surface structure, so that the economical efficiency at the time of attaching can be greatly reduced, and productivity can be greatly improved.

On the other hand, even if the effects are not explicitly mentioned here, the effect described in the following specification, which is expected by the technical features of the present invention, and its potential effects are treated as described in the specification of the present invention.

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention. For convenience, the connection cables of the PCB circuit and the oscillator assembly are not shown and are only shown schematically.

FIG. 1 is a perspective view showing an embodiment of a skin exfoliating beauty machine according to the present invention, FIG. 2 is an exploded perspective view of FIG. 1, and FIG. 3 is a sectional view of FIG.

1 to 3, the skin exfoliation beauty machine 100 according to the present invention includes an upper casing 110 provided with a switch 111, a lower casing 115 coupled with the upper casing 110, A PCB circuit 117 installed in the upper and lower casings 115, and a vibration device.

The vibrating device according to the present invention mainly comprises an amplifying plate 120, vibrator assemblies 130 and 130a, a blade 140, and a joining means.

The amplification plate 120 is made of aluminum, an aluminum alloy, or a substitute thereof, and may have a rectangular shape.

Since the vibrator assemblies 130 and 130a are formed of a piezoelectric ceramic and an insulating plate and may be omitted if necessary, the vibrator assemblies 130 and 130a may be unnecessarily blurred, and a detailed description thereof will be omitted.

A power supply line (not shown) is connected to the vibrator assemblies 130 and 130a. When the power supply is applied, vibration is generated by ultrasonic waves, and the generated vibration is transmitted to the blade 140 through the amplification plate 120 do.

The vibrator assembly may include a first vibrator assembly 130 attached to one surface of the amplification plate 120 and a second vibrator assembly 130a attached to the other surface of the amplification plate 120. However, And either the first oscillator assembly or the second oscillator assembly may be installed.

The uneven surface 121 may be formed on the surface of the amplification plate 120 so that the bonding of the vibrator assembly by the adhesive 123 is made more closely.

The blade 140 has a bending portion 141 which is in contact with the skin at the front end thereof and a rear end portion which is joined to the amplifying plate 120 and is made of stainless steel.

On the other hand, conventionally, the amplifying plate is attached to both long sides of the long blade in a completely overlapped state only by an adhesive, and the vibrator assembly is installed on one or both sides of the amplifying plate. However, when the ultrasonic vibrations are applied to both sides of the long blades, the adhesive attached to the surface of the blade made of the stainless steel material having a smooth surface structure is easily detached structurally. As a result, the size of the ultrasonic vibration transmitted from the vibration plate Respectively.

In order to prevent the adhesive from easily falling off the surface of the blade, the present invention uses a method in which the blade 140 and the vibrator assemblies 130 and 130a are arranged so as not to overlap each other and overlap each other.

Specifically, the length of the blade 140 is formed to be much shorter than the conventional one, and one end surface of the blade 140 is bonded to one surface of the front end portion of the amplification plate 120. The vibrator assembly 130, The blade 140 is spaced apart from the blade 140 in the longitudinal direction. However, the vibrator assemblies 130 and 130a are designed so as to be eccentric to the front end of the amplification plate 120, thereby preventing the degradation of ultrasonic vibration transmission.

In addition, since the bonding surface between the blade 140 and the amplifying plate 120 of the present invention is sharply smaller than the conventional bonding surface, sufficient bonding force can not be ensured only by the adhesive, so that the bonding means of the present invention can be applied to both the physical and chemical bonding methods simultaneously Respectively.

That is, the joining means of the blade 140 and the amplifying plate 120 is based on rubbing with a plurality of rivets 143 which are riveted to the joining surface, And the bonding surface of the blade is further coated with an adhesive 145 to constitute a coupling portion.

The adhesive 145 may be exemplified by an epoxy resin. However, the adhesive 145 may be any adhesive that has properties suitable for surface characteristics of the material used and does not cause skin allergy, and is not limited thereto.

The rivet 143 physically joins the amplifier plate 120 and the blade 140, and when used together with the adhesive 145, the coupling force can be maximized.

In order to rivet the rivet 143, a rivet hole (not shown) is formed in the amplifying plate 120 and the blade 140, respectively. At this time, the rivet hole is equal to or smaller than the diameter of the rivet 143 And is formed slightly larger.

When the adhesive 145 is applied to the bonding surface between the amplifying plate 120 and the blade 140, the adhesive is naturally applied to the rivet hole. If riveting is performed in this state, So that a firm bonding is achieved.

2, when the vibrator assembly is disposed at the central region or the rear end of the amplification plate, the blade may be extended up to the vicinity of the vibrator assembly without overlapping with the vibrator assembly. In this case, Since the area of contact between the blade and the amplifying plate is increased, the adhesive can be bonded without using riveting. However, even in this case, it is most preferable that physical bonding through riveting is performed together with the adhesive.

Hereinafter, a more preferred embodiment of the vibration device of the present invention will be described in detail.

As shown in the photograph of FIG. 6, the amplifying plate and the blade were bonded to each other using an epoxy adhesive and a rivet. At this time, the blade was bonded to one surface of the front end of the amplifying plate, and the pair of vibrator assemblies And was eccentrically attached to the front end portion of the amplification plate to manufacture a vibration device.

A vibration device having the same structure as that of Example 1 was manufactured.

[ Comparative Examples 1 to 10 ]

As shown in the photograph of FIG. 7, a pair of amplifying plates were attached to both sides of the blade with an epoxy adhesive, and a vibrator assembly was bonded on each of the amplifying plates to manufacture a vibrating device.

[ Experimental Example 1 ]

In order to evaluate the performance of the vibration devices of the above-described Examples and Comparative Examples, a water-splash test was conducted. 4, a glass plate is placed on the floor, a drop of water is dropped on a glass plate by a syringe, the distance (d) [mm] in which the water is splashed by the vibration is measured, When the distance was less than 30 mm, it was judged to be defective. The distance (d) [mm] was described in Table 1 (Example) and Table 2 (Comparative Example).
