Description

Portable sterilizer and method of using the same

The present invention relates to a portable sterilizer, and more particularly, to a sterilizer which can be used to sterilize surrounding articles by spraying a sterilizing solution made through electrolysis as a portable.

Recently, there is an increasing awareness of the global epidemic of new viral and bacterial diseases such as swine flu and bird flu. Many of these infectious diseases are known to be effectively prevented through basic preventive methods such as hand washing, and hand cleaners that can be used to wash hands while carrying a lot are commercially available as a preparation for the disease.

Such hand sanitizers and wipes may be suitable for hand washing, but may be suitable for disinfecting or disinfecting suspicious seats, for disinfecting household items that are not suitable for surface cleaning, or for disinfecting by other means. There is a problem in disinfecting and cleaning non-subjects, and it is necessary to use other means for the part of the living body where the mucous membranes, such as the human eye or mouth, are exposed. In addition, the subject may be large or uncomfortable to clean by hand.

Conventionally, in the home or office, such as aerobic disinfection for the purpose of pesticides, spray spray disinfection every corner with a nozzle sprayer used to spray pesticides, but this method of disinfection is too large, It may make you feel uncomfortable with your life and may be too large to carry simply.

Spray spray that sprays through the narrow nozzle hole by applying pressure while sucking the chemical liquid of the container using spray and grip force which put volatile substance and sterilizer in the sealed container and press the valve nozzle to sterilize is also suitable for sterilization. Can be used. However, sprays using volatile materials often cause environmental problems depending on the volatile materials and the one-time use of the containers, and in order to secure economic units, the containers are often large and not suitable for carrying. In addition, since the mechanical spray using the grip force has a size suitable for handholding, the spray device itself is often not suitable for carrying over a certain size.

Therefore, it would be convenient if there is a portable sterilizer which is not burdensome while carrying at the level of a mobile phone, can be freely used at any time, and can be economically used through refilling.

On the other hand, various materials can be used as a disinfectant and a detergent that can be used for sterilization, and various sterilizers have been developed. Among them, the disinfectant used for living goods around the living needs to be excellent in sterilization, but it is required to be safe and economical because the human toxicity is not large.

Examples of the disinfectant as a substance used for sterilization purposes include chlorine (Cl ₂ ), chloramine (NH ₂ Cl), chlorine dioxide (ClO ₂ ), ozone (O ₃ ), and ultraviolet (UV). In general, concentrations of disinfectant of less than 1 ppm in aqueous solution are known to be able to kill a wide variety of microorganisms, including bacteria, viruses, fungi, bacteria and spores. In addition, disinfectants with increased concentration up to several hundred ppm are used in various fields such as waste water and industrial water (eg cooling water), sterilization of fruits and vegetables, sulfite treatment in the petroleum industry, and textile or medical waste treatment. It is known to apply for and provide higher bactericidal properties.

Chlorine, which is most commonly used among these disinfectants and disinfectants, is a chemically stable material, and has a residual property and a low manufacturing cost, and thus is mainly used for disinfection of tap water or disinfection in homes and businesses.

In addition, chlorine (Cl) used as a disinfectant is mostly used in the form of a solution of chlorine gas (Cl ₂ ) or sodium hypochlorite (NaOCl). Sodium hypochlorite (NaOCl) solutions are usually distributed in high concentrations, so handling requires great care.

In addition, sodium hypochlorite (NaOCl) solution is not easy to be stored for a long time due to its high volatility, and is generally provided in high concentration, so it is cumbersome to dilute it every time in actual use, and the concentration when dilute is used. It is difficult to keep constant at all times, so there is a problem that its scope and use is very limited.

In general, chlorine (Cl ₂ ) is a large amount of disinfection by-products that are carcinogenic when disinfection, these disinfection by-products are known to be very harmful to the human body. In addition, when chlorine is used as a disinfectant, a large number of mutant species resistant to chlorine may be generated among the existing bacteria, thereby reducing the effectiveness of disinfection. However, in the examination of alternative disinfectants, most of them are very expensive or have low disinfection effects, and there are difficulties in storage and management, so that replacement is not easy.

In addition, chlorine dioxide, which is a disinfectant of the same chlorine series, is generally low in solubility, relatively inexpensive in terms of cost, and generates very few disinfection by-products, but is difficult and complicated to process. Most of them are used for industrial purposes. A process for producing sterilized water in which a part of chlorine dioxide is dissolved by electrolysis of sodium chlorite solution is already known (Korean Patent Application No. 1020050000219, Korean Patent Application No. 1020090032897, Korean Utility Model Application No. 2020050014692).

SUMMARY OF THE INVENTION An object of the present invention is to provide a portable sterilizer and a method of operating the same, which are portable and have a simple and suitable structure for spraying, which can form a suitable sterilizing substance through electrolysis in itself, and are suitable for miniaturization.

Portable sterilizer of the present invention for achieving the above object, a piezoelectric for generating vibration to discharge the liquid material in the container to the other end by combining with the container at the inlet end, the container that can accommodate the liquid material, the other side A discharge device having an element, a conductor having a passage through which the liquid material passes and spaced behind the discharge device when viewed in a path through which the liquid material is discharged, an AC voltage is applied to the piezoelectric element, and the discharge end and the conductive And a power supply and a circuit device configured to apply a direct current or alternating voltage between the sieves.

In the present invention, as a liquid material, a sodium chlorate solution or a sodium chloride solution may be used to form a chlorine dioxide solution and hypochlorous acid water as a sterilizing material.

In the present invention, the discharge device is provided with a tubular nozzle, the piezoelectric element may be installed so that the expansion and contraction in the direction in which the liquid material passes in the tubular nozzle while wrapping the tubular nozzle in contact with the periphery.

In this case, the conductor may include a mesh-shaped plate having a plurality of holes formed in the plate-shaped body, and the discharge end of the tubular nozzle may extend to the periphery to face the mesh-like plate.

Alternatively, the discharge device may be provided with a mesh-type vibration plate and a ring-shaped piezoelectric element may be attached to one side of the vibration plate so that the vibration plate vibrates in the direction in which the liquid material passes.

In the present invention, the conductor may be provided on the other side of the vibrating plate, and may include a mesh plate having a plurality of holes formed in the plate body.

According to the present invention, it is possible to form a suitable sterilizing material through electrolysis inside itself through a small size and simple configuration suitable for carrying, and immediately by the nozzle using a piezoelectric element which acts as an ultrasonic vibrator. It can be used simply by spraying.

In addition, when the liquid material is discharged, the discharge device, including the discharge device, is disposed at the rear thereof, and an electrolytic electrode is disposed thereon, and only the liquid material discharged to the outside by the discharge device is selectively sterilized by electrolysis. Since the production takes place, the sterilization materials generated by electrolysis can be ejected to the outside at the same time as the production and sterilize, thereby increasing the sterilization efficiency.

That is, in the case where the conductor serving as the electrolysis electrode is installed inside the container at the position before the nozzle, when the use of the sterilizer stops because the molecules or radicals generated by electrolysis remain in the solution inside the container, they are again stopped. Returning to a non-sterile or insufficient solution state results in a loss of energy efficiency for the production of sterilizing substances. In addition, the deposition of radicals in the solution with other substances in the container poses a management burden, such as the need for frequent cleaning of the container, and the inconvenience of frequently changing the solution by consuming limited sterilizing effective substances in the solution. . However, in the present invention, these problems are eliminated because electrolysis is performed only for the solution that will actually be discharged after the nozzle on the discharge path of the solution.

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

1 to 4, the outer case 11 of the portable sterilizer 1 is provided with a button 14 for spraying sterilization water, and an injection 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 20 is installed to open the bucket cover 16 of the case 11 is made of a transparent material so as to know the amount of the solution therein. The inlet 21 of the container 20 is coupled to the inlet end 33 of the nozzle 30, and the coupling method of the inlet 21 and the nozzle 30 may be formed in various forms. For example, the stopper 23 in the form of rubber or urethane foam is fastened to the injection port 21 so that the solution of the container 20 does not easily flow out, and in the center of the stopper 23 by the elasticity of the soft stopper. Normally a closed and energized external force can form a connection hole into which the tube can be inserted. When the container 20 is coupled to the case 11, the inlet end 33 of the tubular nozzle 30 installed in the case 11 is inserted into the connection hole, and the inlet 21 of the container is connected to the case 11. ) Into the connecting groove around the inlet end 33 of the tubular nozzle 30.

Inside the case 11, a nozzle seal top is formed of a silicon material and forms a part of the outer shell of the nozzle seal bottom 43 forming the connection groove and the nozzle opening 13 of the case. top: 41, and a tubular nozzle 30 made of metal penetrating them serves to connect them. Nozzle nuts 45 and 47 having angled portions are installed between the tubular nozzles 30 and the metal nozzles 30 to prevent rotation thereof. A longitudinal middle portion of the tubular nozzle 30 is placed in the empty space (gap) between the nozzle seal top 41 and the nozzle seal bottom 43. In this portion, two ring-shaped piezoelectric elements 51 are provided side by side around the nozzle 30. The piezoelectric element 51 can act as an efficient ultrasonic oscillator according to the alternating frequency applied. Referring to FIG. 4, between two piezoelectric elements 51, one ring-shaped electrode terminal 53 is installed so as not to contact the body of the tubular nozzle 30 at a portion where the diameter of the tubular nozzle 30 is reduced so that the AC power source 83 is connected. One pole of is connected. Two ring-shaped electrode terminals 55 are respectively provided on the outer side of the two piezoelectric elements 51, and they are commonly connected to the other electrode of the AC power source 83 in common. Therefore, while the AC power source 83 is applied to the two piezoelectric elements 51, the contraction and elongation are repeated in the longitudinal direction of the tubular nozzle 30 to cause vibration in accordance with the AC waveform in the tubular nozzle 30.

According to the exemplary embodiment, only one ring-shaped piezoelectric element may be installed, and two electrodes of AC power may be connected to both sides of the piezoelectric element based on the longitudinal direction of the tubular nozzle.

The vibration of the piezoelectric element 51 by the action of alternating current forms a kind of standing wave in the tubular nozzle 30. The solution inlet end 33 of the tubular nozzle 30 is buried in a solution filling the inside of the container 20 to form a stationary end of the standing wave, and the discharge end 31 on the injection port 13 side is connected to an open outer side. Therefore, by forming the free end of the standing wave, the solution is discharged to the outside through the nozzle 30.

In this embodiment, a tubular nozzle 30 including a piezoelectric element 51 is used for solution spraying, which is a tubular nozzle 30 comprising a piezoelectric element 51 in comparison with other mechanical spraying devices. It can be installed in small size with simple structure, and it can be used conveniently because it is possible to make the AC power suitable for injection using the circuit for electrolysis. In addition, it is suitable for the construction of a small portable sterilizer by reducing the assembly difficulty or the need for installation space.

On the other hand, as can be seen in the conceptual diagram of Figure 4, between the tubular nozzle 30, that is, the discharge end 31 of the tubular nozzle and the mesh assembly 60 of the injection port should be provided with a direct current power source 81 for generating a direct voltage . For example, a DC voltage is applied by connecting a (−) electrode to the tubular nozzle discharge end 31 and connecting a (+) electrode to the mesh assembly 60. The solution coming out of the discharge end 31 of the nozzle 30 is sprayed into the particulate form through the mesh assembly 60 in the process, due to the DC voltage applied between the discharge end 31 and the mesh assembly 60 in the process. When electrolysis is carried out and the solution is for example brine, hypochlorous acid water with hypochlorite (HOCl), which has disinfecting power, is produced by 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.

To explain the process further, by electrolysis of sodium chloride (NaCl) solution, chlorine ions (Cl ⁻ ) by ionization of sodium chloride are attracted to the anode, and electrons are lost from the anode to become chlorine molecules (Cl ₂ ). Chlorine molecules react with the surrounding water molecules (H ₂ O) to generate hypochlorous acid (HOCl), chlorine ions and hydrogen ions (H ⁺ ). Hypochlorite forms hypochlorite water in the form dissolved in water.

As soon as hypochlorous water is produced, most of it is discharged to the outside through the mesh assembly of the nozzle in the form of fine 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.

Depending on the type of sterilizing material desired, the type of solution and its applied voltage can be varied. For example, sodium chlorite solution may be used as the solution, and chlorine dioxide solution may be made from the sterilizing material.

The mesh assembly 60 may be simply made of one mesh plate, but is formed by interposing another annular spring washer 63 between the mesh plate 65 and the annular washer 61 for ease of installation and voltage application. You may. These parts of the mesh assembly 60 are typically all made of metal.

In order to fix the mesh assembly 60 at a predetermined distance from the discharge end 31 of the nozzle, a silicone component, which is an insulator such as the nozzle ring top 71 and the nozzle ring bottom 73, is used. The spacing between the mesh assembly and the nozzle discharge end creates a space in which the electrolysis of the solution exits the discharge end and before being injected into the jet.

Since the sterilizing material released through the mesh assembly 60 may contain various corrosive substances, it may corrode the electrode in the form of a mesh in the spraying step, and in this case, it is necessary to replace the mesh assembly in a short cycle. . Therefore, the mesh assembly 60 may be made of a material such as stainless steel or titanium, which is resistant to corrosion, or plated with a material resistant to corrosion, so as to withstand the corrosive material contained in the sterilizing material. It can be formed by plating platinum on stainless steel. In addition, as mentioned earlier, electrolysis may be performed by using an alternating voltage to prevent electrode material wear from being concentrated on only one electrode, thereby reducing the electrode replacement cycle.

In this configuration, the sterilizing substances produced between the two electrolysis electrodes are immediately released to the outside through the nozzle and come into contact with the object to disinfect. Therefore, the rate at which once produced sterilizing substances return to the solution state before electrolysis over time is reduced, so that the rate of participation in disinfection is reduced, and the energy used for electrolysis can maximize the effect of contributing to disinfection. .

In addition, as compared with the case in which the sterilization material such as hypochlorous acid generated by electrolysis in the solution container is discharged through the nozzle, the sterilization material remains in the solution container and does not participate in disinfection, but again in the original solution form. In addition, some of the sterilizing material may be combined with impurities in the original solution or the container itself to form a precipitated material and adhere to the inner wall of the container, thereby preventing the container from being difficult to manage.

Although only a conceptual form is shown in FIG. 4 and no specific form is shown, it is, of course, an electrode terminal 53 or 55 for applying an alternating voltage to the piezoelectric element 51 of the tubular nozzle 30 or a direct current for electrolysis in the case. A circuit device and a power supply device for applying a voltage to the electrode are provided. (Other parts are shown in cross section in Fig. 4, but the electrode terminals of the piezoelectric elements are shown as straight lines connected and treated as side views).

In other words, a power supply device is naturally required for the formation of sterilizing sterilization material by electrolysis, and a circuit device for applying a voltage to the electrolysis electrode is required. In addition, although the type of voltage applied to the electrolysis electrode and the type of voltage applied to the piezoelectric element is different, it is possible to install the converter in one PCB installed in the case, so that one additional space will not be needed. It is also possible to supply a direct current or alternating voltage for electrolysis from the power supply and an alternating voltage for driving a nozzle with a piezoelectric element.

Figure 5 is a plan view showing another embodiment of the present invention, Figure 6 shows a side cross-sectional view accordingly.

This configuration assumes that the front end of the piezoelectric element 150 is in contact with the solution of the container inside the injection port in the solution path, and the rear end of the mesh assembly or the mesh plate 160 is connected to the outside of the injection port. At this time, the tubular nozzle 30 with the piezoelectric element as shown in the embodiment of Figure 4 is not provided, it is assumed that the connecting tube of the similar shape as the tubular nozzle connects the solution inlet and the injection portion as part of the container. Can be.

The injection port portion is provided with a mesh vibration plate 130 on the front side (container side), and the rear end side (outside) of the injection hole to atomize the sterilizing material that is forced to be released to the outside by the vibration plate 130 The mesh plate 160 is installed. A piezoelectric element 150 for vibrating the vibrating plate 130 is installed at the front end of the vibrating plate 130 on the solution path. Although not shown, the front and rear surfaces of the piezoelectric element 150 are connected to one of two electrodes of the AC power, and an AC voltage is applied thereto. The piezoelectric element 150 is vibrated while being stretched according to the voltage, and even if there is no separate check valve, the vibrating plate 130 attached to the piezoelectric element 150 vibrates and vibrates the vibrating plate 130. The solution in the side of the container filled with the furnace solution is moved by the force toward the mesh-shaped plate 160 of the injection hole connected to the external empty space.

Each of the mesh plate 160 and the vibration plate 130 is connected to one of two electrodes of the DC power source, and a DC voltage is applied between the two electrodes. For example, the positive potential is applied to the mesh plate 160 and the negative potential is applied to the vibration plate 130. Electrolysis is performed in the solution in the path from the vibration plate 130 to the mesh plate 160 by this DC voltage. A silicon pad 170 as an insulator is installed between the vibrating plate and the mesh-shaped plate to maintain insulation between the two plates, and filled with a solution to form a space where electrolysis is performed. The mesh plate 160 is divided into a central area in which a plurality of discharge holes 167 are formed and an outer area without discharge holes.

Since the electrolysis action in this space is substantially the same as the electrolysis action between the widespread tubular nozzle discharge end and the mesh assembly in the embodiment as shown in FIG. 4, further description will be omitted.

As in the previous embodiment, the gas or bubble generated in this space during the electrolysis process increases the pressure in the space, or acts like a bubble generated inside the hydraulic system to move the solution from the diaphragm to the mesh plate. Since the force received can be attenuated, the power applied to the piezoelectric element is controlled so that the sterilizing material resulting from the electrolysis can be sprayed to the outside with sufficient force.

In addition, by applying power to the piezoelectric element first and applying electrolysis power by delaying time, a technique of sequentially controlling the injection may be used. In this case, the result of electrolysis during use is prevented from remaining inside the sterilizer. You may. In view of this, when the sterilizer is stopped, the electrolysis power is first cut off and the piezoelectric element is cut off after a time delay so that bubbles do not remain inside the container.

Hypochlorite water sprayed in the form of an aerosol will act to sterilize and disinfect the object in contact with the sterilized object. The concentration of hypochlorous acid water is very constant, and the brine discharged is electrolyzed at a predetermined uniform rate, so that it can be kept constant at all times. Hypochlorous acid is easily produced by using hydrogen peroxide in the human body and can be viewed as a safe substance generated by the human body when bacteria invade.

Therefore, hypochlorous acid water sprayed in the present invention set to an appropriate concentration in the human body is not toxic to the human body can be exposed to the hands or face, mouth, sofa or bedding, toys, tableware and the like with confidence.

Therefore, the sterilizer of the present invention can be used for disinfection of hands, clothes, bedding, deodorization of mouth, disinfection of office desks or office supplies, disinfection of the inside of a vehicle, spraying on the face combined with humidification and the like.

According to the configuration of the sterilizer as in the present invention, a sterilizer in the form of a rectangular parallelepiped of a mobile phone can be manufactured and easily used, and can be easily sterilized by a spray method without having to wipe an object requiring sterilization and disinfection anywhere. In addition, it is possible to increase the utilization of the sterilization and sterilization materials obtained by electrolysis since the electrolysis is performed immediately after the electrolysis on the path where the solution is discharged to the solution discharged to the outside by the nozzle using the piezoelectric element.

In the case of a woman wearing makeup, not only does the makeup be deformed at all, but the sterilizing water can be applied to the wound so that it does not flow down, so the beauty effect can be expected. The overall effect of the present invention is to produce sterilized water as described above and release fine water particles to the outside as a sanitary device and can be used as a humidifier and a beauty moisturizing device, if the medical aids meet the requirements asthma system As it can be applied to the patients, the application method of the use can be applied more diversifiedly.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
