  As shown in FIG. 1, the vibration element 10 according to the present invention includes an annular ultrasonic transducer 46 having an upper electrode on the front surface, and a vibration unit 42 located at the back of the annular ultrasonic transducer 46 in the center. And the elastic housing 20 surrounding the outer periphery of the lower electrode 44.

  The vibration part 42 provided at the center of the lower electrode 44 is formed of a circular thin plate, and a step is formed so that the back surface of the lower electrode 44 protrudes along the outer periphery thereof. Is provided with a number of liquid discharge holes h.

  The elastic housing 20 is preferably provided so as not to contact the annular ultrasonic transducer 46 in order to maximize the vibration efficiency, but is provided so as to cover the front surface of the annular ultrasonic transducer 46. May be. In this case, there is an advantage that the leakage of the liquid moving to the front side of the annular ultrasonic transducer 46 can be effectively blocked. In FIG. 1, only a partial shape of the elastic housing 20 is shown to refer to the shapes of the annular ultrasonic transducer 46, the lower electrode 44, and the vibrating portion 42.

  The lower electrode 44 and the vibration part 42 are integrally formed, and the thickness of the vibration part 42 is thinner than the thickness of the lower electrode 44, so that the back surface of the lower electrode 44 is the outer periphery of the circular vibration part 42. A step is formed so as to protrude along the line.

  The annular ultrasonic transducer 46 is a piezoelectric ceramic, and atomizes the liquid supplied to the vibrating portion 42 by applying vibration to the vibrating portion 42 formed integrally with the lower electrode 44. To do.

  Here, as a reference for distinguishing the front surface and the back surface, a surface formed in the direction in which the upper electrode is positioned in the annular ultrasonic transducer 46 is referred to as a front surface, and a surface positioned in the opposite direction of the front surface is referred to as a back surface. In addition, when the vibration element 10 is actually attached to a portable moisture supply device 100 (FIG. 2), which will be described later, the front surface is located in the front direction facing the portable moisture supply device 100, and the back surface is It is located in the back direction facing the portable water supply device 100.

  The vibration element 10 according to the present invention has a circular thin plate vibrating portion 42 integrally formed at the center portion of the lower electrode 44. Therefore, the vibration element 10 is very simple in structure, but the thin ultrasonic plate is formed from the annular ultrasonic transducer. There is an advantage that vibration can be efficiently transmitted to the oscillating portion 42.

  That is, in the related art, the annular ultrasonic transducer and the diaphragm or the vibration membrane are configured not to be in direct contact with each other. However, in the vibration element 10 according to the present invention, the lower electrode 44 has an annular ultrasonic wave. Since it is in direct contact with the vibrator and the lower electrode 44 and the vibrating portion 42 are integrally formed, vibration efficiency is excellent.

  Further, since the elastic housing 20 surrounds the outer periphery of the lower electrode 44, the vibration of the vibrating portion 42 is not restrained by the elasticity of the elastic housing 20 while the lower electrode is fixed, and the vibration efficiency. There is also an advantage that is excellent.

  Hereinafter, the present invention will be described in more detail with reference to preferred embodiments. However, these embodiments are for explaining the present invention more specifically, and do not limit the scope of the present invention.

  Preferably, the elastic housing 20 is made of an elastic polymer and fixes the outer periphery of the lower electrode 44 but does not restrain the vibration of the vibration part 42.

  Examples of elastic polymers include styrene block copolymers, olefin elastomers, vinyl chloride elastomers, chlorinated polyethylene elastomers, urethane elastomers, polyester elastomers, polyamide elastomers, fluorine elastomers, silicon elastomers, etc. It is done.

  However, the type of the elastic polymer for manufacturing the elastic housing 20 is not limited thereto, and when the vibration element 10 is mounted on the portable moisture supply device 100, the elastic housing 20 and the portable moisture supply device 100 are used. Any liquid can be used as long as the liquid does not leak from the coupling position.

  As shown in FIG. 2, the portable water supply device 100 according to the present invention includes the vibration element 10, a storage tank 110 that stores the liquid supplied to the vibration element 10, and the storage tank 110 is detachable. A storage tank storage chamber 131 is formed on the upper rear surface, and includes an outer case 130 having a spray hole 132 formed on the upper front surface.

  The elastic housing 20 of the vibration element 10 has a through hole 22 formed in the thickness direction, and the spray hole 132 so that the atomized liquid is discharged from the vibration part 42 to the spray hole 132. And the storage tank 110.

  Here, a discharge portion insertion tube 24 into which one side of the storage tank 110 is inserted may protrude from the back surface of the elastic housing 20 positioned on the storage tank 110 side.

  The storage tank 110 includes a container 112 that stores the liquid w, and a discharge unit 114 that is formed at a lower end of the container 112 and discharges the liquid w. Therefore, the discharge part insertion tube 24 of the elastic housing 20 is connected to the discharge part 114, and the liquid w in the storage tank 110 can be immediately supplied to the vibration part 42 without being washed away.

  In addition, the outer case 130 may further include a spray tube 134 having one end connected to the spray hole 132 and the other end coupled to the elastic housing 20.

  Here, the back refers to the back of the thing. That is, the discharge direction of the liquid w atomized from the portable water supply device 100 according to the present invention is the front direction, and the back surface is a surface located on the opposite side of the front surface.

  In general, the water supply device discharges water by converting it into particles, and types thereof include a centrifugal spray type, an ultrasonic type, an electrothermal type, and a filter vaporization type. The centrifugal spray type is a method in which the sucked water is blown away by centrifugal force to form particles, and the electrothermal type is a method in which water is heated by a heater or an electrode rod to generate steam. The filter vaporization type evaporates water by passing air between the filters, and the ultrasonic type generates an electrical signal of a specific frequency in an electric circuit and transmits it to a vibrator placed in water. If ultrasonic waves are generated, cavitation, which is a vacuum phenomenon that occurs after a propulsion unit or the like, is generated, and fine fog particles are generated.

  The portable water supply device 100 according to the present invention is an ultrasonic type device that atomizes the liquid w, and ultrasonic waves are generated from the annular ultrasonic transducer 46 to atomize the liquid w. Here, the annular ultrasonic transducer 46 is a piezoelectric ceramic. That is, a piezoelectric shape in which electrical energy is converted into mechanical energy is generated by the resonance phenomenon of the annular ultrasonic transducer 46, thereby generating ultrasonic waves.

  In the case of a general ultrasonic vibrator, the frequency band of the vibrator for atomizing the liquid is about 1.5 MHz, whereas the frequency band of the annular ultrasonic vibrator 46 according to the present invention. Is 90 kHz to 500 kHz, and noise due to vibration is less than that of a general ultrasonic vibrator. In addition, since the elastic housing 20 is coupled to the outer periphery of the lower electrode 44, vibration transmitted to the outer peripheral surface of the lower electrode 44 is absorbed by the elastic housing 20, and the portable moisture supply according to the present invention is performed. The noise of the device 100 can be minimized.

  The liquid discharge hole h in one embodiment of the present invention can have the same diameter on both ends as shown in FIG. Alternatively, in another embodiment, the liquid discharge hole h can be tapered so that the diameter on the storage tank 110 side is larger than the diameter on the spray hole 132 side.

  The vibrating portion 42 has a liquid discharge hole h, but the liquid w in the storage tank 110 does not leak into the liquid discharge hole h before a separate force is applied. That is, the liquid w can be prevented from leaking into the liquid discharge hole h due to the balance of 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 in a tapered shape as in the other embodiments, it can be seen that the attractive force between the liquids acts strongly on the liquid droplets spilled at the end of the liquid discharge hole h.

  Before describing the attractive action between liquid molecules, several terms are defined. That is, when the molecules of the liquid w located in the liquid discharge hole h form 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 liquid molecular layer located in the region is called a surface layer, and the liquid molecular layer that contacts the surface layer and attracts the surface layer is called an attractive layer.

  It can be seen that the vibration unit 42 according to another embodiment of the present invention has a greater number of liquid molecules in the attractive layer, and thus the force of attracting the liquid molecules in the surface layer from the attractive layer of the vibration unit 42 acts more strongly.

  However, the liquid discharge hole h of the vibration part 42 according to the present invention discharges the liquid w only when a separate force is applied regardless of its shape. Accordingly, as described above, the surface tension, the adhesion force, the attractive force, and the like of the liquid are balanced, so that the vibration element 10 causes the liquid w to be applied only when a separate force other than gravity is applied to the vibration unit 42. A certain amount can be discharged and atomized.

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

  The liquid w remains in the liquid discharge hole h due to the surface tension, but the vibrating portion 42 that vibrates by the annular ultrasonic transducer 46 causes the liquid w that has been spilled in the liquid discharge hole h due to the vibration. It comes to hit. At this time, a vacuum phenomenon (cavitation) occurs on the back side of the vibrating part 42, the liquid w becomes fine particles like mist, and the atomized liquid w moves to the spray tube 134 side while moving to the skin. To be supplied.

  Here, since the annular ultrasonic transducer 46 vibrates in a certain direction, even if the portable water supply device 100 according to the present invention is not provided with a separate fan, the particulate liquid becomes the annular ultrasonic wave. It can move to the spray hole 132 side by receiving a force from the vibrator 46. Accordingly, since noise and power consumption due to fan operation are reduced, the battery can be used for a long time and can be easily used in a quiet place.

  Moreover, since the fan does not need to be mounted, there is an advantage that the portable water supply device 100 according to the present invention can be reduced in size and weight. Furthermore, since no filter is required, the length of the discharge part 114 to which the vibration element 10 is coupled can be made shorter than that of the conventional one, and the portable water supply device 100 can be downsized.

  The elastic housing 20 is coupled to the discharge unit 114 and at the same time to a packing fixing bar 136 projecting from both sides of the spray tube 134, thereby being more firmly coupled into the portable water supply device 100. sell. In FIG. 2, the packing fixing bars 136 are shown to be positioned in the vertical direction, but the position is not limited to the vertical direction and may be formed to be in the horizontal direction.

  The liquid w atomized as described above is discharged to the outside through the spray tube 134 and the spray hole 132. At this time, in order to prevent the atomized liquid particles from being liquefied again, the spray tube 134 according to an embodiment of the present invention is tapered such that the diameter increases toward the spray hole 132 side. It is formed in a shape. Thus, by forming the spray tube 134 in a tapered shape, it is possible to prevent the atomized liquid discharged to the outside from colliding with the spray tube 134 and being liquefied.

  The spray tube 134 may be manufactured by mixing tourmaline ore or tourmaline ore powder with a polymer material such as plastic. Moisture supplied to the skin is supplied together with anions by passing through the spray tube 134, or a magnet 117 is provided in the discharge part 114, and the water in the container 112 is made into a magnetized water state and supplied to the skin. can do. In this case, it is preferable to use a magnet 117 having a magnetic flux density of 11000 gauss or more so that water can be easily magnetized water.

In general, tourmaline is a borosilicate having hexagonal columnar crystals and is a natural mineral belonging to the hexagonal system. The tourmaline crystal has a property of generating electricity and is also called tourmaline. Such tourmaline crystals continue to generate a weak current suitable for the body, and when the water touches the crystals, water is instantaneously electrolyzed, and hydroxyl anions (H ₃ O ₂ ) are generated. To alkalinize the water to approximately pH 7.4. By such an action, if the water is supplied to the skin, not only water having an excellent moisturizing effect is supplied to the skin, but also cell functions are activated.

  As shown in FIG. 2, when the magnet 117 is provided in the discharge unit 114, hydrogen constituting the water molecule moves toward the N pole side of the magnet 117 and oxygen tends to move toward the S pole side due to the magnetic force. appear. As a result, water molecules rotate rapidly. At this time, 15 to 20 water molecules collide with the negative charges formed in the magnetic field, and after the water molecules are subdivided in the previous water molecule cluster, they are recombined to form 5 to 6 water molecules. Forms a cluster of water molecules. Such water is called magnetized water.

  As described above, the water can be easily absorbed into the cell while reducing the number of water molecules forming one cluster. And since the magnetized water evaporates slowly, it can maintain moisture in the skin for a long time.

  The portable water supply apparatus 100 according to an embodiment of the present invention can be turned on / off using the power button 152, but the power is turned on / off by the controller 160 depending on the position of the lid 156. It can also be controlled.

  The portable water supply device 100 includes a lid 156 for preventing dust from entering the vibrating part 42 through the spray tube 134 or damage to the vibrating part 42 due to foreign matter being inserted when not in use. be able to.

  For example, when the outer case 130 and the lid 156 are slidably coupled, the portable moisture supply device 100 may be turned off when the lid 156 covers a part or the whole of the spray hole 132. it can. Therefore, in this case, even when the power button 152 is pressed, the portable moisture supply device 100 can be prevented from being driven.

  In addition, when the lid 156 is moved upward so that the spray hole 132 is completely opened, the control unit 160 can supply power to drive the portable moisture supply device 100. At this time, the portable water supply device 100 can be turned on / off through the power button 152.

  That is, the lid 156 is opened to clean the spray hole 132 and the spray tube 134, but when the portable moisture supply device 100 is not required to be driven, the portable moisture supply according to the present invention is performed through the power button 152. The power supply of the apparatus 100 can also be turned off. In addition, even if the power button 152 of the portable water supply device is pressed in a wallet or handbag, and the lid 156 is closed, the portable water supply device is not driven even if the power button 152 is pressed. Can be controlled.
