In addition, the guide shaft formed on the drive shaft is guided, so when the puff comes into contact with the skin, there is no shaking before, after, left or right, and the cosmetics can be evenly applied to the skin. The puff is driven using a coil and a magnet. The present invention relates to a tapping applicator that can be applied evenly in a small size to drive the puff up and down to act on the skin when it comes into contact with the skin to apply the cosmetic evenly to the skin.

In general, cosmetics are used to naturally cover the blemishes and blemishes of the skin exposed to the outside, such as the face, or to nourish the skin.

Such kinds of cosmetics include various cosmetics such as foundation cosmetics, skin covers or powders, nutrition creams, massage creams, and facial cleansing products.

On the other hand, the foundation of the above-mentioned color cosmetics is also used a lot to cover the blemishes and blemishes of the skin exposed to women and recently men.

The foundation is generally formed in the form of a fine powder or liquid and is generally applied by touching the area to be used by the user.

In particular, the foundation is a reality that much depends on the user's skill level to be applied evenly spread without agglomeration on the part to be made.

In addition, in the case of nourishing cream or massage cream, in order to smoothly absorb the cream on the skin, the user must repeatedly tap and penetrate into the skin.

In order to solve this problem, various types of vibration puffs that can automatically apply cosmetics such as foundation or cream have been developed.

Figure 1 relates to a Patent No. 10-1107002 (knob puff with a built-in vibration means).

Looking at the configuration of the prior art, the cover body 210 is provided with a handle 211, the inside of the cover body 210, the battery 232 for supplying power by the operation of the switch 233 ) And a vibrator comprising a vibrator 231 supplied with power through the battery 232.

In addition, a support 240 including a vibration plate 242 connected to the vibrator 231 of the vibration means is configured, and the puff pad 250 is configured above the support 240.

Accordingly, when the switch 233 of the vibration means is turned on, the control board 234 supplies power to the vibrator 231 to generate vibration, and the vibration generated is the vibration plate of the supporter 240. The puff pad 250 connected to the 242 and the shaking plate 242 is delivered to act to evenly apply the cosmetic to the user's skin.

On the other hand, Figure 2 relates to a Utility Model Registration No. 20-0456112 (vibration puff).

The prior art illustrated in FIG. 2 is configured to be driven through a motor driven in a normal forward and reverse rotation manner unlike in FIG. 1.

That is, as shown in FIG. 2, the rotating center shaft 314 is rotatable inside the cases 312a and 312b, and the power is supplied to the side of the rotating center shaft 314 through the power supply means 328. Winding coil 322 is configured.

In addition, the rotation center shaft 314 is configured with a yoke 338 and a rotation means including a weight 334 and a permanent magnet 336 which are formed in only one direction.

In addition, the diaphragm 316 and the puff 318 are formed above the rotating means and the central axis 314.

Therefore, when the power supply means 328 supplies power, the power is applied to the winding coil 322 to rotate the rotation means together with the rotation center shaft 314 by interaction with the permanent magnet 336 of the rotation means. Done.

At this time, the permanent magnet 336 of the rotating means is caused by the eccentric vibration by the weight 334 formed in only one direction, the vibration generated in this way is transmitted to the diaphragm 316 and puff 318 to vibrate It works to deliver.

Next, Figure 3 relates to the registration utility model No. 20-0455561 (vibration puff).

The prior art shown in FIG. 3 employs a structure capable of generating vibration through piezoelectric ceramics.

That is, the prior art includes a battery unit 438, a switch 439 and a pulse generator 436 periodically applying or blocking current in the lower case 410.

In addition, an actuator 434 made of a piezoelectric ceramic to receive current from the pulse generator 436 and a speaker 430 composed of a protrusion 432 and a flat plate 431 connected to the actuator 434 are configured. The puff pad 450 is configured above the speaker 430.

Accordingly, when the switch 439 is turned on, the power of the battery unit 438 is applied to the pulse generator 436, and the pulse generator 436 is applied to the actuator 434 while periodically applying and cutting off the power, and is puffed. And acts to vibrate the pads 450.

Next, FIG. 4 relates to Korean Patent Laid-Open Publication No. 10-2011-0071042 (vibration foundation).

In the prior art of FIG. 4, a vibration coil 520 is configured inside the case 510, and a permanent magnet 550 moving in the vibration coil 520 and a vibrator 530 connected to the permanent magnet 550. Consists of.

In addition, the upper side of the vibration coil 520 has a structure consisting of a noise preventing nonwoven fabric 525.

In the conventional art of FIG. 4, when the power supply polarity is applied to the vibrating coil 520 with different power polarities, the linear motion can be performed using the optical axis magnetic force (Fleming's left hand law) generated when the current is interlinked with the magnetic flux. It will work.

However, since the prior art (registered patent 10-1107002) of the above structure is made in such a manner as to drive the vibrator 231 through a battery 232 having a relatively small amount of power supply, a constant intensity cannot be formed during vibration. There was a problem.

This method does not directly drive the puff but gives vibration only by vibrator. It is not only weak in intensity of vibration but also can not be equipped with means to control the intensity of vibration. There were no drawbacks.

In addition, the prior art (Registration Utility Model No. 20-0456112) also generates vibration through the rotating method of the vibrator as described above, so that only the vibration is provided instead of directly driven by the puff, so that the amount of vibration is small so that the user's needs cannot be met. do.

In particular, when the vibration is generated through this rotation method, the period in which the vibration occurs is changed according to the strength of the driving force. When the strength of the driving force is weakened, the period of the vibration becomes too long, resulting in agglomeration of cosmetics. In addition, when the strength of the driving force is increased, the cycle is too short, and the cosmetics are applied to the skin of the user so thin that the coverage is not good.

That is, the structure as described above does not meet the strength and vibration period of the vibration required by the user has a problem that the merchandise deterioration.

In addition, the prior art (registered utility model 20-0455561) of FIG. 3 also has a problem that the intensity of vibration is very low as in the prior art as described above.

In particular, the piezoceramic is a device whose length varies when the power is supplied, and it is very difficult to form a constant level of vibration intensity only by the current of the battery unit 438 in the form of a small battery. It has been pointed out that it is very difficult to generate the frequency of the cycle.

In addition, the prior art of FIG. 4 (Patent No. 10-2011-0071042) also has a problem that the strength of vibration is weak as in the above-described techniques.

That is, in the prior art of the structure as described above, the intensity generated by the driving force in the optical axis direction is proportional to the magnetic flux density in the air gap generated on the magnetic circuit between the current applied to the vibration coil 520 and the permanent magnet 350. .

Here, the void portion means a space between the vibration coil 520 and the permanent magnet 350.

Therefore, in order to improve the driving force (vibration strength), one or both of the above two factors must be raised.

Here, since the current applied to the vibration coil 520 always operates constantly because a battery is normally used, the permanent magnet 550 is used to increase the magnetic flux density in the magnetic field in the prior art as shown in FIG. 4. You need to increase the size of.

However, increasing the size of the magnet as described above not only increases the overall size of the product, but also increases the unit cost of the magnet to increase the overall product cost.

In particular, in the case of forming the noise preventing nonwoven fabric 525 on the upper side of the vibration coil 520 through which current flows, the vibration coil 520 may be damaged by a collision during vibration, and deformation and disconnection may occur, resulting in a decrease in magnetic force or an operation. There is a problem that can not ensure the reliability of the product is not made.

In addition, since the permanent magnet 550, which is relatively heavy, is driven, not only the above-described damage of the vibration coil 520, but also the reaction rate by the applied current is relatively slow, so that the adjustment of the vibration intensity and the number of vibrations is performed. This difficult problem was also exposed.

Here, in the case of the power supply means 70 may be formed to form a separate space inserted into the structure, in this case, the power supply means 70 of the charging method through a secondary battery or a conventional battery type battery Any one can be selected and used.

Looking at the effect of the present invention made of a configuration as described above are as follows.

First, the current input in one direction through the power supply means 70 connected to the terminal portion 43 of the spring 40 is via a coil wire cw connecting the spring 40 and the coil C. A current is applied to the coil C.

The applied current is the drive shaft 30 to which the coil C is coupled while the magnetic flux generated in the magnet 52 of the magnet part 50 adjacent to the coil C and the current flowing in the coil C are interlinked. ) And the puff p are generated to move in the up and down directions.

That is, the interaction between the coil C coupled to the coil coupling part 32 of the drive shaft 30 and the magnet 52 of the magnet part 50 will be described briefly. The coil is placed in a magnetic field composed of a magnet and a magnetic induction part. When the current is applied in one direction, the coil is forced by the Lorentz force, and the force is generated in the direction perpendicular to the direction in which the current and the magnetic field are perpendicular to each other by Fleming's left hand law.

Therefore, when the magnet part 50 including the magnet 52 is fixed to the housing part 11 of the case 10, the drive shaft 30 to which the coil C and the puff p are coupled is upward. , Will be moved in any one direction.

In the present invention, by using this phenomenon it is repeated to change the direction of the current applied to the coil (C) through the polarity change acts so that vibration can occur.

On the other hand, as described above, the drive shaft 30 including the coil (C) and the puff (p) by the magnet 52 of the magnet unit 50 must maintain a constant strength, the user tapping applicator 100 of the present invention When using cosmetics in puff (p) when used, the cosmetics can be used smoothly without agglomeration phenomenon, the most important factor at this time is the amount of current applied to the coil (C) and the coil (C) generated on the magnetic circuit ) And the magnetic flux density in the space between the magnet 52 (hereinafter referred to as the 'gap portion').

That is, when either one of the above two conditions is high, the strength of the driving force increases.

Here, the magnet 52 of the magnet unit 50 is a magnetic force is moved from the N pole to the S pole direction as shown in FIG.

In particular, as described above, in order to increase the strength of the driving force, an optimal magnetic circuit should be designed to maximize the magnetic flux density generated in the air gap as much as possible.

The easiest way to increase the magnetic flux density is to use a high-strength magnet. In general, it is natural that a large-size magnet should be used because it is made of a neodymium (Nd-Fe-B) magnet. .

However, the tapping applicator 100 of the present invention is limited in overall size, and furthermore, when a large magnet is used, a problem arises in that the burden on the consumer is increased by the increase in manufacturing cost.

Accordingly, in the present invention, the lower yoke 51 and the upper yoke 53 made of ferromagnetic material are formed on the basis of the magnet 52 of the magnet part 50 so as not to use the high Gaussian magnet 52. If not, it can work to solve it.

As shown in FIG. 7, the upper and lower yokes 53 and 51 made of a ferromagnetic material prevent the magnetic force lines generated from the magnet 52 from spreading to the outside.

That is, since the high magnetic flux density can be formed in the gap portion through the upper and lower yokes 53 and 51, when the same current is applied, a large force is generated in the magnet portion 50, so that the coil C and the puff ( It is to act to increase the driving force strength of the drive shaft 30 is coupled to p).

In particular, the current applied to the coil (C) as described above is the polarity conversion is made by the control unit 60 when the current is applied to the spring 40, if the driving force is increased as described above, the repetitive up and down movement When the vibration force is generated through, the strength of vibration is increased to generate the vibration force (the force of hitting the skin) of the level required by the user.

FIG. 9 is an analysis diagram simulating a magnetic force line generated by the tapping applicator of FIG. 4, and FIG. 10 is an analysis diagram simulating a magnetic force line generated at the tapping applicator of the present invention.

Here, the magnets applied in FIGS. 9 to 10 used magnets having the same magnetic flux.

9 to 10, in the conventional vibration puff 500, as shown in FIG. 9, the magnetic flux density in the gap between the permanent magnet 550 and the vibration coil 520 is illustrated in FIG. 9. It can be seen that there are many differences with the magnetic flux density generated in the tapping applicator 100.

This is a state in which the magnetic resistance is large because the air gap is wide in the conventional case, but in the present invention, the magnetic flux density through the upper and lower yokes 53 and 51 and the magnetic resistance are reduced to reduce the magnetic flux density. have.

Therefore, in the present invention, even if the power supply means uses a power supply means having a low current amount, such as a battery type such as a battery or a rechargeable battery through a secondary battery, the vibration force required by the user can be obtained.

On the other hand, in the present invention, the spring 40 is formed between the case 10 and the upper cover 20 has a structure coupled to the drive shaft 30.

The spring 40 has a vibration strength and a vibration period by causing the force to act in a direction in which the elastic force of the spring 40 increases it when the driving shaft 30 is driven in one direction and then drives in the opposite direction. It will work to improve.

In addition, in the present invention, when the current is applied to the spring 40 and the coil (C), it is configured to be able to adjust the vibration period and the vibration intensity through the control means 60.

That is, the control means 60 adjusts the supply amount of the current applied to the coil C to adjust the vibration intensity by adjusting the polarity conversion period of the current applied to the coil C and the first control unit 61 and the vibration frequency. The 2nd control part 62 for adjusting this is comprised.

Therefore, the user can adjust the vibration intensity or slow or speed up the current polarity conversion cycle so as to adjust the user's preference and the type of cosmetics to be applied.

In particular, in the present invention, a method in which the coil C, which is lighter than the magnet 52, is driven.

That is, even if the user increases the frequency using the second control unit 62 of the control means 60, if the weight of the drive shaft 30, the coil C, and the puff p, which operate up and down, becomes heavy, Reaction speed is slowed according to the user narrows the range of choice for adjusting the frequency, in the present invention because the weight of the drive shaft 30 is coupled to the actual driving coil (C) and puff (p) is light 2 will act to quickly respond to the polarity change of the control unit 62.

In addition, in the present invention, the guide shaft 33 is extended to the lower end of the drive shaft 30 for driving in the up and down directions, and the lower yoke of the magnet part 50 can guide the guide shaft 33. The first, second, and third holes h1, h2, and h3 are formed in the 51, the magnet 52, and the upper yoke 53, so that the user engages with the upper end of the drive shaft 30 through a puff p. When the foundation is in contact with the skin, the drive shaft 30 acts to apply the foundation evenly to the skin by preventing the phenomenon that the drive shaft 30 shakes left and right.

In particular, in the process of moving the drive shaft 30 up and down by the coil (C) and the magnet 52 of the magnet portion 50 when using the tapping applicator 100 of the present invention, the upper cover 20 And there is room for noise while hitting the upper end of the upper yoke 53 of the magnet portion 50, in the present invention is to act to reduce such noise through the first, second noise prevention portion (S1, S2).

In addition, in the case of the second noise prevention part S2, the first, second, and third holes h1, h2, and h3 are formed in the lower yoke 51, the magnet 52, and the upper yoke 53 of the magnet part 50. Since it is manufactured in a form that can be inserted into the inside of the guide shaft 33 of the drive shaft 30 acts to reduce the noise that may occur in the process of being guided.

Although the above-described embodiment is described with respect to the most preferred embodiment of the present invention, the present invention is not limited to this and can be modified in various forms without departing from the technical spirit of the present invention. It is obvious to those skilled in the art.
