Description

Portable electronic sprayer and its operation method {mobile electronic sprayer and method of operating the same}

The present invention relates to a nebulizer and a method for operating the same, and more particularly, to a spraying method and a suitable configuration for a portable electronic nebulizer equipped with a power supply and automatically spraying the chemical liquid by using ultrasonic vibration.

Portable electronic nebulizer has been developed to give a humidifying function mainly for the purpose of skin beauty, and recently in the Republic of Korea Patent Application No. 2011-0078671 filed by the applicant of the present invention a variety of new viral diseases such as influenza and bird flu In addition, the present invention discloses a portable sterilizer for disinfecting and disinfecting a human body part or a peripheral article in consideration of an awareness of the global epidemic of bacterial diseases, and an electronic nebulizer is also applied thereto.

In such an electronic nebulizer, an ultrasonic vibrator is placed on the path of the chemical liquid stored inside the nozzle end to obtain power required for spraying, and the ultrasonic vibrator is electrically driven.

By the way, such a portable electronic nebulizer needs to be kept small in size to facilitate portability, but as the size of the portable nebulizer decreases, the volume of the stored chemical liquid that can be used also decreases, requiring frequent changes or refilling of the chemical liquid container. There is discomfort.

In addition, the chemical solution is often sprayed at a close distance, but the chemical solution does not spread at a wide enough angle, but concentrates on a part of the skin or an object, and the chemical solution washes and smears the makeup, or mist-like fine water droplets are sprayed onto the surface of the spray object. It is easy to cause the problem of gathering and falling down. In particular, when the chemical liquid is expensive, the effectiveness of the chemical liquid is reduced, and the cost for using the chemical liquid becomes too high, making it uneconomical.

It is conceivable to reduce the power applied to the ultrasonic vibrator and the control circuit to reduce the spray liquid continuously sprayed, but the spray amount of the chemical liquid is not reduced in proportion to the power reduction used. Sometimes it is impossible. That is, depending on the spraying device, there is a problem that it can exceed the appropriate amount of spraying per hour (for continuous spraying) that can already be used easily and adjustable at the minimum power level required to start spraying.

To reduce this problem, use a nebulizer to continuously spray but continuously spray the nozzle position with your hand holding the nebulizer, or use a hand to control the spray volume while interrupting the power switch applied to the ultrasonic vibrator. And spraying may be considered.

However, these methods have a problem that it is inconvenient because the hands need to keep moving, and it is difficult to control the spray amount constantly and properly. In particular, intermittent spraying of the chemical liquid by intermittent operation of the power supply switch to the ultrasonic vibrator makes it difficult to control the spray amount uniformly, and even a driving time of the ultrasonic vibrator may cause a delay time.

An object of the present invention is to provide a portable electronic nebulizer and a method of operating the same, which can reduce the number of replacement and replenishment of the chemical solution while maintaining a compact size for portable use.

The present invention enables the economical use by reducing the amount of chemical liquid spray by preventing the spray of excessive chemical liquid, over a limited area of the chemical liquid, and portable electronics that can reduce the inconvenience, such as makeup smear caused by excess spray, the liquid flow down An object of the present invention is to provide a nebulizer and its operation method.

The portable electronic nebulizer of the present invention for achieving the above object is a space for storing the chemical liquid therein, the nozzle is connected to the space and the chemical liquid passage to be an outlet to discharge the chemical liquid to the outside, located in the passage or nozzle of the chemical liquid and Ultrasonic vibrator driven to give the discharge pressure to the chemical liquid, and control the electrical signal waveform through software or firm by hardware or programmable integrated circuit chip by control IC chip with necessary electronic circuit. By intermittently applying an electric signal to the ultrasonic vibrator it is characterized in that the intermittent spray is made.

The portable electronic nebulizer of the present invention is made to reduce the spray amount of the chemical liquid sprayed by intermittent spraying during the operating time compared to the minimum spraying amount during the operating time such as continuous spraying, the intermittent spray in the present invention is particularly driven by electricity The chemical liquid emitted by the ultrasonic vibrator may be applied to a sterilizer which electrolyzes an electrode disposed in a path after the ultrasonic vibrator to create a sterilizing material.

Portable electronic nebulizer operating method of the present invention,

A space for storing the chemical liquid inside, a nozzle connected to the space and the chemical liquid passage to be an outlet for discharging the chemical liquid to the outside, and an ultrasonic vibrator positioned in the passage or the nozzle of the chemical liquid and electrically driven to discharge the chemical liquid. In spraying the chemical liquid to the outside through the nozzle by applying pressure to the chemical liquid by the vibration of the ultrasonic vibrator in the portable electronic nebulizer, the spray amount of the chemical liquid sprayed by two or more times per second during the operating time is reduced compared to the minimum spraying quantity It is characterized in that it is made to be.

Intermittent spraying in the method of the present invention may be made 2 to 12 times, preferably 3 to 10 times a second, too few sprays do not benefit from intermittent spraying, at 12 or more levels The effect of varying the number of sprays per second may be difficult to implement the circuit as compared to the small effect.

Intermittent spraying in the method of the present invention may be achieved by applying a voltage to the ultrasonic vibrator, for example, having a pulse wave waveform as a whole, and having a high frequency alternating waveform for ultrasonic vibration in the individual pulse wave.

In the method of the present invention, when the ultrasonic vibrator is driven by the pulse wave, it is also a characteristic of the pulse wave itself, but the tip of the pulse wave has a steep slope so that the voltage applied to the ultrasonic vibrator rapidly decreases to 0 after passing the voltage application time from the driving voltage. It is desirable to. As a result, the chemical liquid spray amount does not end as it gradually decreases, and a group of fine droplets sprayed cleanly by spraying at a predetermined time point may spread out at a wide solid angle from the nozzle.

According to the present invention, it is possible to efficiently spray the chemical liquid while keeping the overall size small, thereby reducing the trouble of replacing and replenishing the chemical liquid, and preventing the spraying of the excessive chemical liquid and the spraying of the chemical liquid on an excessively limited area. By reducing the cost, economical use is possible.

According to the present invention, the spray form is able to achieve a wide three-dimensional angle, reducing the discomfort such as intensive spray, over-spray, medicament dripping, when the woman wearing makeup when used for a facial moisturizer, portable sterilizer, etc. Not only does makeup not deform at all, but sterilized water can be applied to the wound to prevent it from dripping down.

In addition, the amount of spray can be finely adjusted according to the time, and can be used in various ways such as a spray dosage controller if the medical aid is met.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The outer case 11 of the portable sterilizer 1 is provided with a button 14 for spraying sterilization water, and a spray hole 13 for spraying sterilization water is formed. When not in use, a cover 18 for covering and protecting the injection hole 13 is also provided.

The container installed by opening the bucket cover 16 of the case 11 is made of a transparent material so as to know the amount of the solution therein.

Looking at the nozzle 20 of the assembly form consisting of an ultrasonic vibrator, a vibrating plate, a mesh, etc., as shown in Figure 3, in the front of the path of the chemical (hereinafter, the front and rear is the chemical container side based on the path of the chemical) The outside connected to the front nozzle is determined to be the rear side.) The ultrasonic vibrator 21 and the vibrating plate 22 are integrally coupled to each other, and a mesh 23 is provided at the rear thereof. An insulator spacer 24 is provided between the mesh and the vibration plate for insulation between the two.

The ultrasonic vibrator 21 is formed in a substantially donut shape and is formed of a piezoelectric element using a piezoelectric phenomenon, and is connected to a lead wire for applying a vibration voltage although not shown on the front and rear surfaces thereof.

As the vibrating plate 22 attached to the ultrasonic vibrator 21 vibrates, the solution on the side of the chemical container filled with the solution around the vibrating plate 22 is applied to the mesh 23 connected to the external empty space. Will be moved.

The mesh 23 may be divided into a central area in which a plurality of holes 231 are formed and an outer area having no discharge hole and overlapping the front insulator spacer. The mesh 23 meets the chemical liquid in the process of discharging the chemical liquid through the vibrating plate 22 to the nozzle outlet, and serves to make the chemical liquid into finer fine water droplets.

With this configuration, when the ultrasonic vibrator 21 is vibrated by receiving power from the outside, the vibrating plate 22, which is integrally attached, also vibrates to give pressure to move the chemical solution toward the mesh, and to pass through the mesh. Spray the chemical in the form of a fine mist.

The cylinder holder 10 has a long cylindrical shape, and forms a tapered hollow shape in which the hollow shape becomes narrower toward one end of the cylinder holder 10. Its interior is empty so that the drug solution can flow in.

A stage is formed inward at one end of the cylinder holder 10, and a projection 12 for supporting the ultrasonic vibrator is formed at the end of the inner side (toward the central axis of the cylinder holder). The projection 12 is narrower in width toward the rear so as not to lower the vibration of the ultrasonic vibrator and the vibrating plate 22.

In addition, a fixing ring 30 is coupled to the rear of the mesh 23 to fix the nozzle to this end, and a lead wire groove 15 for drawing lead wires is formed inside the wall surface perpendicular to the end. The lower surface of the fixing ring 30 is combined with a silicone ring 31 for fixing the nozzle 20 better.

In the hollow wall surface of the cylinder holder 10, the drug movement passage 17 for facilitating the movement of the drug solution is formed as a groove having a 'V' shaped cross section along the longitudinal direction of the cylinder holder 10. The drug movement passage 17 mitigates the cohesive force such as surface tension when the chemical solution moves from the chemical liquid container 40 to the nozzle 20 to facilitate the flow of the chemical liquid by allowing the chemical liquid to be sucked along the chemical movement passage 17. At the same time, the sprayed and sucked by the cohesive force to smoothly flow the drug into the nozzle (20).

A stage is formed at the other end of the silicon holder 10 so as to be coupled to the chemical container 40, and the silicon holder 10 and the chemical container are formed on the end and a wall perpendicular to the end. After the 40 is coupled, an air inlet 41 is formed to allow air to flow into the silicon holder 10. The air inlet 41 may prevent the movement of the chemical liquid by forming a vacuum in the chemical liquid container 40 while the chemical liquid is sprayed.

As can be seen in the conceptual diagram of FIG. 3, two electrodes of the AC power source 51 are connected to the front and rear surfaces of the ultrasonic vibrator 21 through a lead wire in the nozzle for vibration of the ultrasonic vibrator. The AC power source 51 generates an AC waveform voltage signal having a corresponding period in ultrasonic waves. A switching element 53 is connected in series with the lead wire, and one signal line of the control IC chip for transmitting the pulse signal for intermittent injection is connected to the switch element 53 again. As the switch element, an electronic component such as a simple switching transistor may be used, or a plurality of electronic components for making a more complicated switching circuit may be used.

When the control IC applies a pulse signal 3 to 10 times per second to the switch element 53 according to a signal from another power supply, when the pulse signal is displayed as 'ON' or '1', ultrasonic waves are transmitted to the ultrasonic vibrator through the lead wire. When an AC waveform having a frequency corresponding to is applied and the pulse signal is displayed as 'OFF' or '0', the lead wire is electrically disconnected so that the AC power voltage is not applied to the ultrasonic vibrator.

Thus, intermittent spraying is achieved, for example, by applying a voltage to the ultrasonic vibrator, which has a macroscopic, overall pulsed wave waveform, and has a high frequency alternating waveform for ultrasonic vibration in a respective pulse wave envelope.

When driving the ultrasonic vibrator by pulse wave, it is also characteristic of the pulse wave itself, but it is desirable that the end of the pulse wave is inclined so that the voltage applied to the ultrasonic vibrator rapidly decreases to 0 after the voltage application time at the driving voltage. Do. In other words, the pulse wave ideally has an absolute absolute value of inclination, but in reality, the slope of the front and rear ends of the electric pulse is not infinite, and the gradient value is made as large as possible here. As a result, the chemical liquid spray amount does not end as it gradually decreases, and a group of fine droplets sprayed cleanly by spraying at a predetermined time point may spread out at a wide solid angle from the nozzle. This is similar to a phenomenon in which cigarette smoke creates a ring shape or donut shape when it is blown out intermittently by shocking the smoke.

On the other hand, between the mesh 23 having a large number of holes 231 and the vibrating plate 22 made of a mesh shape, although not clearly shown in the drawing, two electrodes of a DC power source are connected to each other to generate a potential difference. This potential difference causes the solution, such as brine, that enters the chemical container to be delivered to the nozzle, into hypochlorous acid water with hypochlorous acid (HOCl), which is disinfected through electrolysis.

It is not necessary to apply a direct voltage to the electrolysis, and the same chemical action may be performed while changing the pole even when applying an alternating voltage. In this case, it is possible to solve the problem that the electrode metal material is worn out to deflect (in the ionization process of the metal) or the corrosion occurs during the electrolysis of the two electrodes alternately.

As soon as hypochlorous water is produced, most of it is released through the mesh to the outside as particulate water droplets. Since this hypochlorous acid has high disinfection power, it can disinfect and clean the spray object. Hydrogen is combined with water molecules to form hydronium ions (H ₃ O ⁺ ), which can be sterilized by acidity and perform various functions depending on their acidity.

In the nozzle 20, the mesh 23 and the vibrating plate 21 are separated by an insulator spacer 24, and a silicon component may be used as the insulator spacer.

In this configuration, the sterilizing materials produced between the two electrolysis electrodes are immediately released to the outside through the nozzle outlet and sterilize by touching the object. Therefore, once produced sterilizing substances return to the solution state before the electrolysis over time, it is possible to prevent the phenomenon of participating in the disinfection action, and maximize the effect that the energy used for the electrolysis contributes to the disinfection action. .

Although the type of voltage applied to the electrolysis electrode and the voltage applied to the ultrasonic vibrator are different, it is possible to install the converter in one PCB installed in the case, so that no additional space will be required. It is also possible to supply an AC voltage for driving a nozzle with a piezoelectric element separately while supplying a DC or AC voltage for decomposition.

On the other hand, in the case of spraying using an ultrasonic vibrator, a clogging phenomenon may occur in which the chemical liquid is not smoothly released, but it may be considered that foreign matters are deposited on the path of the chemical liquid, but a clogging phenomenon may occur even when bubbles or bubbles are generated inside the chemical liquid. May occur. In particular, in the sterilizer as in the present embodiment, gas is easily generated in the space between the mesh where the electrolysis is performed and the vibrating plate to form bubbles or bubbles, and the generated bubbles increase the pressure in the space or are generated inside the hydraulic power unit. By acting as a bubble to attenuate the force received by the solution moving from the vibration plate to the mesh may cause clogging phenomenon.

In addition, it is preferable to reduce the size of the mesh hole and increase the pressure in the process of passing through the mesh to spray the chemical liquid evenly at a wide solid angle, but if the hole is small, it is difficult to overcome the surface tension of the chemical liquid at the start of spraying.

In order to overcome the blockage caused by bubbles or the surface tension at the start of spraying, it is necessary to drive the ultrasonic vibrator with a larger spray pressure, that is, a higher ultrasonic vibrator driving voltage.

When the conventional spraying is a problem, in spite of these problems, it is difficult to sufficiently supply the voltage and power used for chemical spraying, but in the present invention, the spraying is performed through the ratio of the time that spraying is performed during the entire time while intermittent spraying. Can be prevented.

Therefore, by reducing the ratio of the actual spraying time of the total operating time in the intermittent spray using the present invention, increasing the voltage of the AC power supply to vibrate the ultrasonic vibrator can increase the pressure at the time of spraying without the problem of overspray The conventional clogging phenomenon in the electronic injector can be overcome by itself, and it can overcome the surface tension and facilitate chemical spraying.

Furthermore, in the present invention, unlike continuous spraying, a plurality of sprays are performed within a short time, in which case the impact force is transitioned to a transitional phenomenon due to the electromagnetic causes and the mechanical causes from the fluid characteristics as the spraying state is changed from stop to start. This impact force can heal itself and overcome the initial surface tension.

While the invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
