EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

Vibration element 10 according to the present invention, as shown in Figure 1, an annular ultrasonic vibrator 46 is provided with an upper electrode on the front;

A lower electrode 44 disposed on the rear surface of the annular ultrasonic vibrator 46 and integrally provided with a vibrator 42 in the center thereof; And

It includes an elastic housing 20 surrounding the outer circumference of the lower electrode 44,

The vibrating portion 42 provided at the center of the lower electrode 44 is a circular thin plate, and a step is formed so that the rear surface of the lower electrode 44 protrudes along the outer circumference thereof, and a plurality of liquids are formed at the central portion of the circular thin plate. It is characterized in that the discharge hole (h) is provided.

As shown in FIG. 1, the elastic housing 20 is preferably provided so as not to be in contact with the annular ultrasonic vibrator 46 to cover the front surface of the annular ultrasonic vibrator 46. It may be provided to. In this case, there is an advantage that the leakage of the liquid moving to the front side of the annular ultrasonic vibrator 46 can be effectively blocked. In FIG. 1, only some shapes of the elastic housing 20 are illustrated to refer to the shapes of the annular ultrasonic vibrator 46, the lower electrode 44, and the vibrator 42.

Since the lower electrode 44 and the vibrator 42 are integrally formed, and the thickness of the vibrator 42 is thinner than the thickness of the lower electrode 44, the bottom surface of the lower electrode 44 is Steps are formed to protrude along the outer circumference of the circular vibrator 42. In addition, the annular ultrasonic vibrator 46 is a piezoelectric ceramic, and applies vibration to the vibrator portion 42 formed integrally with the lower electrode 44 to atomize the liquid supplied to the vibrator portion. Will be.

Here, the reference for distinguishing the front and the back, the surface formed in the direction in which the upper electrode is located in the annular ultrasonic vibrator 46 is called the front, and the surface located in the opposite direction of the front is divided into the rear surface. In addition, when the vibrating element 10 is actually mounted to the portable water supply device 100, the front surface is located in the front direction toward the front of the portable water supply device 100, and the rear surface is portable water supply. It is located in the back direction toward the back of the supply device (100).

The vibrating element 10 according to the present invention has a very simple configuration because the vibrating portion 42 of a circular thin plate is integrally formed at the center of the lower electrode 44, but the vibration of the vibrating annular ultrasonic vibrator is thin. There is an advantage that can be efficiently delivered to (42). That is, in the related art, although the annular ultrasonic vibrator and the diaphragm or the vibration membrane are not directly in contact with each other, in the vibrating device 10 according to the present invention, the lower electrode 44 is in direct contact with the annular ultrasonic vibrator and the lower electrode 44 ) And the vibrator portion 42 are integrally formed, so that the vibration efficiency is excellent. In addition, since the elastic housing 20 surrounds the outer circumference of the lower electrode 44, the lower electrode is fixed and the vibration of the vibrator 42 is not constrained due to the elasticity of the elastic housing 20. It also has the advantage of excellent efficiency.

Hereinafter, the present invention will be described in more detail with reference to preferred examples. It will be apparent to those skilled in the art, however, that these examples are provided to further illustrate the present invention, and the scope of the present invention is not limited thereto.

The elastic housing 20 is made of an elastomer and preferably fixed to the outer circumference of the lower electrode 44 so as not to restrict the vibration of the vibrator 42.

Examples of the elastomer include styrene block copolymers, olefin elastomers, vinyl chloride elastomers, chlorinated polyethylene elastomers, urethane elastomers, polyester elastomers, polyamide elastomers, fluorine elastomers, silicone elastomers, and the like. However, the type of the elastomer for manufacturing the elastic housing 20 is not limited thereto, and when the vibrating device 10 is mounted on the portable moisture supply device 100, the elastic housing 20 and the portable moisture may be used. Anything can be used as long as the liquid does not leak at the engaged position of the feeder 100.

2 is a cross-sectional view of the portable water supply device.

Portable moisture supply device 100 according to the present invention, as shown in Figure 2, the vibration element 10;

A storage container 110 in which a liquid supplied to the vibrating element 10 is stored; And

A storage container storage chamber 131 in which the storage container 110 is detachably received is formed on an upper rear surface, and an upper case 130 includes an outer case 130 having a spray hole 132 formed therein.

The elastic housing 20 of the vibrating element 10, the through hole 22 is formed in the thickness direction, the atomizing liquid from the vibrating portion 42 to discharge the spray hole (132) 132 and is characterized in that coupled between the reservoir (110).

In this case, a discharge part insertion tube 24 into which one side of the storage container 110 is inserted may protrude from the rear surface of the elastic housing 20 located at the storage container 110 side. As shown in FIG. 2, the storage container 110 is a container 112 in which the liquid w is stored and a discharge part 114 formed at a lower end of the container 112 to discharge the liquid w. It includes. Therefore, while the outlet insertion tube 24 of the elastic housing 20 is coupled to the outlet 114, the liquid w in the reservoir 110 is not lost and is directly supplied to the vibrator 42. It can be.

In addition, one end of the outer case 130 may be connected to the spray hole 132, and the other end may further include a spray pipe 134 that is coupled to the elastic housing 20.

The back here refers to the back side of the object. That is, the direction in which the atomized liquid w is discharged from the portable water supply device 100 according to the present invention is a front direction, and the rear surface refers to a surface located on the opposite side of the front surface.

In general, the moisture supply device is the principle of discharging the granulated water, the type is centrifugal spray, ultrasonic, electrothermal, filter evaporation. In the centrifugal spraying method, inhaled water is blown into a centrifugal force to granulate. In the electrothermal type, water is heated by a heater or an electrode to generate steam. In addition, the filter evaporation type is to evaporate water by passing air between the filters, and the ultrasonic type generates an electric signal of a specific frequency in an electric circuit and transfers it to a vibrator placed in the water to generate ultrasonic waves. The cavitation occurs to produce fine mist particles.

The portable water supply device 100 according to the present invention is to ultrasonically granulate the liquid (w), the ultrasonic wave is generated in the annular ultrasonic vibrator 46 to atomize the liquid (w). The annular ultrasonic vibrator 46 is a piezoceramic. That is, a piezoelectric shape in which electrical energy is converted into mechanical energy is generated by the resonance phenomenon of the annular ultrasonic vibrator 46, and thus ultrasonic waves are generated.

In addition, in the case of a general ultrasonic vibrator, the frequency band of the vibrator for atomizing liquid is approximately 1.5 MHz, whereas the frequency band of the annular ultrasonic vibrator 46 according to the present invention is 90 kHz to 500 kHz, so noise due to vibration is common. Less than ultrasonic vibrator In addition, since the elastic housing 20 is coupled to the outer circumference of the lower electrode 44, the vibration transmitted to the outer circumferential surface of the lower electrode 44 is absorbed by the elastic housing 20 so that the portable body according to the present invention is portable. The noise of the water supply device 100 may be minimized.

The liquid discharge hole (h) according to an embodiment of the present invention, as shown in Figure 2, the diameter of both ends of the liquid discharge hole (h) can be formed to be the same. In addition, as in the liquid discharge hole (h) according to another embodiment of the present invention, the liquid discharge hole (h) is formed in a tapered shape such that the diameter of the reservoir 110 side is larger than the diameter of the spray hole 132 side. It may be.

Although the liquid discharge hole h is perforated in the vibrating unit 42 according to the present invention, the liquid w in the storage container 110 does not leak into the liquid discharge hole h until a separate force is given. That is, the liquid w can be prevented from leaking into the liquid discharge hole h through the balance between the surface tension of the liquid w and the adhesion force of the liquid w. In particular, when the liquid discharge hole (h) is formed as a taper, as in another embodiment of the present invention, it can be seen that the attractive force between the liquid strongly acts on the liquid droplets formed at the end of the liquid discharge hole (h).

Some terms are summarized before describing the attractive force interaction between liquid molecules. When the molecules of the liquid (w) located in the liquid discharge hole (h) forms a layer, and the liquid (w) forms a droplet at the end of the liquid discharge hole (h) on the spray hole 132 side by the surface tension The molecular layer of the liquid located on the surface of the droplet may be referred to as a surface layer, and the liquid molecular layer in contact with the surface layer and attracting the surface layer may be called an attractive layer. Since the vibrator portion 42 according to another embodiment of the present invention has a larger number of attractive layer liquid molecules, a force that attracts the liquid molecules of the surface layer in the attractive layer of the vibrator portion 42 acts more strongly. Can be.

However, the liquid discharge hole h of the vibrating unit 42 according to the present invention discharges the liquid w from the liquid discharge hole h only when a separate force is applied regardless of its shape. Accordingly, as the surface tension, adhesion force, and attraction force of the liquid are balanced as described above, the vibrating element 10 is provided with the liquid w only when a separate force other than gravity is applied to the vibrator 42. It can be discharged by a certain amount to be atomized (霧化).

The process of atomizing the liquid w by the driving of the vibration device 10 is as follows.

Due to the surface tension, the liquid w remains in the liquid discharge hole h. The vibrating portion 42 vibrated by the annular ultrasonic vibrator 46 is vibrated by the liquid discharge hole h. It hits the liquid (w) that is bound to. At this time, a vacuum phenomenon (cavitation) occurs on the back side of the vibrator 42, the liquid (w) becomes fine particles like fog, the atomized liquid (w) toward the spray tube 134 side It is supplied to the skin as it moves.

Here, the annular ultrasonic vibrator 46, because the vibration occurs in a predetermined direction, even if the portable water supply device 100 according to the present invention does not have a separate fan, the granulated liquid is the annular ultrasonic vibrator Force from the 46 can be moved to the spray hole 132 side. Therefore, the noise and power consumption due to the operation of the fan is reduced, so that the battery can be used for a long time and can be used easily regardless of a quiet place, and the fan does not need to be installed, and thus the portable moisture supply device 100 according to the present invention (100). ) Can be reduced in size and weight. In addition, since no filter is required, the length of the discharge part 114 to which the vibrating element 10 is coupled may be shorter than that of the related art, and thus, the portable water supply device 100 according to the present invention may be miniaturized. Do.

The elastic housing 20 is coupled to the discharge portion 114, and also coupled to the packing fixing bar 136 protruding on both sides of the spray tube 134, thereby, in the portable moisture supply device 100 It can be combined more firmly. In FIG. 2, the packing fixing bars 136 are shown to be disposed in the vertical direction, but the position is not limited to the vertical direction but may be formed to be in the horizontal direction.

The atomized liquid w as described above is discharged to the outside through the spray tube 134 and the spray hole 132. In this case, in order to prevent the atomized liquid particles from being liquefied again, the spray tube 134 according to an embodiment of the present invention may be formed in an inclined shape so as to increase in diameter toward the spray hole 132. have. By forming the spray tube 134 in a tapered shape as described above, it is possible to prevent the atomized liquid discharged to the outside from hitting the spray tube 134 to liquefy.

In this case, the spray tube 134 is mixed with tourmaline ore or tourmaline ore powder with a polymer material such as plastic so that the water supplied to the skin through the spray tube 134 is supplied with anion, or the discharge unit 114 ), A magnet 117 may be provided so that the water in the container 112 is supplied to the skin in a state of magnetized water. At this time, the magnet 117 uses a magnetic flux density of 11000 gauss or more so that water can be easily magnetized water. In general, tourmaline is a borosilicate having a hexagonal columnar crystal and is a natural mineral belonging to a hexagonal system. The tourmaline crystal is also called tourmaline because it has the property of generating electricity. These tourmaline crystals continue to generate a weak current suitable for the body, and when the water reaches the crystals, the water is absorbed by the hydroxyl anion (H ₃ O ₂ ), which is generated by electrolysis of the water. Be angry. When the moisture is supplied to the skin by this action, not only the moisture having excellent moisturizing effect is supplied to the skin but also the cellular function is activated. In addition, as shown in FIG. 2, when the magnet 117 is provided in the discharge part 114, hydrogen constituting water molecules by magnetic force moves toward the N pole of the magnet 117 toward the S pole. This causes the water molecule to spin quickly. In this case, the water molecules are subdivided in the previous water molecule cluster, which is composed of 15 to 20 water molecules by colliding with the negative charge formed in the magnetic field, and then recombined to form one cluster of 5 to 6 water molecules. Such water is called magnetized water. As described above, as the number of water molecules forming one cluster is reduced, the moisture can be easily absorbed into the cell, and the magnetized water can maintain moisture for a long time because the evaporation is slow.

The portable water supply device 100 according to an embodiment of the present invention may be turned on / off using the power button 152, but according to the position of the cover 156 through the control unit 160. It can also be controlled to turn on / off the power.

The portable moisture supply device 100 may include a cover to prevent dust from entering the vibrating part 42 or inserting foreign substances into the vibrating part 42 through the spray tube 134 when not in use. 156 may be further provided.

For example, when the outer case 130 and the cover 156 is slidingly coupled, when the cover 156 covers a part or the whole of the spray hole 132, the portable moisture supply device 100 ) Can be turned off. Therefore, in this case, even when the power button 152 is pressed, the portable moisture supply device 100 may not be driven. In addition, when the cover 156 is moved upward so that the spray hole 132 is fully open, the portable moisture supply device 100 may be driven by supplying power from the controller 160. In this case, the portable moisture supply device 100 may enable on / off control even through the power button 152. That is, when the cover 156 is opened to clean the spray hole 132 and the spray tube 134, and the driving of the portable moisture supply device 100 is unnecessary, the cover 156 is viewed through the power button 152. It is also possible to turn off the power of the portable moisture supply device 100 according to the invention. In addition, even when the power button 152 of the portable water supply device is pressed in a pocket or handbag, the cover 156 is closed, so that the portable water supply device is not driven even when the power button 152 is pressed. can do.
