Description

Sterilizer using atomized drugs{STERILIZER USING ATOMIZED DRUGS}

The present invention relates to a sterilizer capable of disinfecting a liquid disinfectant by vibrating (atomizing into ultrafine particles) with an ultrasonic vibrator, and more particularly, to a disinfecting agent that can be disinfected by an ultrasonic vibrator. And, it relates to a sterilizer using an atomized agent that allows you to visually see the ejection scene of the atomized agent from the discharge port,

In addition, it relates to a sterilizer that forms an airflow so that the atomized drugs are always discharged along the exhaust system without flowing back, and also generates a thrust to accelerate the airflow toward the outlet in the exhaust system,

In addition, it is a sterilizer that can effectively disinfect even in a confined space where it is difficult to access the sterilizer.

In addition, it relates to an unmanned sterilizer that is installed in a place where vehicle access and visits are frequent, so that anyone can easily self-disinfect the interior of the vehicle.

The sterilizer defined in the present invention may differ in the dictionary sense, but encompasses devices or devices that perform sterilization, sterilization, and sterilization based on an atomized drug for quarantine.

Currently, coronavirus infectious disease-19 (hereinafter referred to as "infectious disease") is prevalent around the world, and the government's related agencies have infectious disease infection prevention and management procedures and measures for multi-use facilities used by an unspecified number of people. Hygiene rules for the prevention of infectious diseases have been published.

As is well known, infectious bacteria contaminate not only people who come into contact with or face to face when the infected person moves, but also the facilities visited or handled, so that all suspected infections, facilities, and/and objects handled by the suspect are completely disinfected. Should be.

According to the above guidelines for the prevention of infectious diseases, it is instructed that people with suspected infectious diseases use their own vehicles instead of public transportation when visiting the screening center (or specialized hospital) to prevent secondary transmission. There are obvious reasons for disinfecting a car (or vehicle).

However, the interior of a car contains materials that are susceptible to water or moisture, or various electric/electronic devices, and is scattered with thin and deep grooves (or gaps, holes) or out of reach, and effectively protects the interior of a small space. There is an urgent need for a way to disinfect.

The currently used method of disinfecting the interior of a vehicle is to spray the drug into the vehicle using a sprayer and then wipe it with a dry rag or wipe the interior with a rag soaked with the drug.

Although this disinfection method can have some disinfection effect, it is difficult to effectively disinfect deep holes (or grooves) such as cold/hot air vents, stepped parts, and parts that are out of reach. There is discomfort.

The above-described problem is partially solved by the creation of Korean Patent Publication No. 10-2004-0087750 (published date: October 15, 2004, "a device for vaporizing and spraying a drug using an atomized drug"), but there are still many problems to be solved. I have tasks to do.

The above-described Korean Patent Publication No. 10-2004-0087750 proposes an apparatus for vaporizing and disinfecting a medicament capable of evaporating a medicament into fine particles using ultrasonic waves and spraying it onto an object to be sterilized.

As a solution for solving the problem, it is characterized in that a gasification spraying device for a drug is proposed that sucks out the vaporized disinfectant in the vaporization tank by installing a blower on the top of the vaporization tank and sprays it through the outlet.

The vaporization spraying device of the above-described drugs creates a negative pressure inside the vaporization tank by rotating the blades of the blower, and sprays the vaporized disinfectant through the discharge port using the negative pressure in the vaporization tank. Is the way,

However, since the above-described vaporization spraying device is difficult to enter into the vehicle interior, it is possible to disinfect the interior of the vehicle by coupling a flexible hose to the discharge port, but when the vaporized disinfectant passes through the rotor blades of the blower, the rotating blades Because it is discharged while being liquefied by a spiral vortex, it is not possible to see a scene where the disinfectant is ejected in the form of a mist from the end of the discharge port, and the chemical aggregated on the inner wall of the hose flows along the hose and contaminates the interior of the vehicle. do.

In addition, most of the known atomizing disinfectants maintain their efficacy regardless of whether or not the disinfectant is atomized, but the disinfectant discharged from the disinfectant based on the atomized agent (or disinfectant) is visible and visible. There is a very important semantic difference in terms of the reliability of the disinfecting effect between what cannot be done.

In addition, smoke-screen sterilizers are also known. As described in Korean Patent Application Laid-Open No. 10-2020-0028557, the smoke screen sterilizer is a method of disinfecting with a fired smoke screen by burning a mist/smoke diffusion agent mixed with water, biodiesel, glycerin, ginkgo leaf extract, and phytoncide amino acid, It is mainly used for pest control. The above published patent publication 10-2020-0028557 allows the disinfection effect to be predicted by the smoke screen because the smoke screen can be visually seen, but the above disclosed patent is suitable for indoor disinfection purposes for vehicles because the smell of combustion gas remains indoors for a while. It's hard to say.

In addition, registration patent 10-0954869 (registration date: 2010. 04. 19, portable sterilizer using an ultrasonic vibrator) is also known, but this technology also does not have access to solving the problems described above.

According to this background, the present inventors have come to invent in order to solve all the problems of the conventional sterilizer as described above, and have remarkable achievements, so that the present invention intends to propose this.

The main object of the present invention is to provide a sterilizer using an atomized agent that can visually see the ejection scene of the atomized agent by transporting the atomized drug by an ultrasonic vibrator in an atomized state to a greater distance.

Another object of the present invention is to provide a sterilizer using an atomized agent that forms an airflow that always flows along an exhaust system without the atomized agent flowing back.

Another object of the present invention is to provide a sterilizer using an atomized medicament having a thrust capable of accelerating the airflow toward the outlet of the exhaust system.

Another object of the present invention is to provide a sterilizer using an atomized agent capable of pushing and spraying the atomized agent.

Another object of the present invention is to provide a sterilizer using an atomized drug capable of effectively disinfecting a space where access to the sterilizer is difficult.

Another object of the present invention is to provide an unmanned sterilizer using an atomized drug that can be easily self-sterilized by anyone by placing it in a place where vehicle access or visitation is frequent.

Solutions for implementing the object of the present invention,

In a sterilizer for disinfecting by spraying an atomized disinfectant by an ultrasonic vibrator,

In blowing the outside air into a container (hereinafter referred to as "coma") where the diluent for diluting the disinfectant stock solution and the disinfectant stock solution is mixed, there is a characteristic of a sterilizer using an atomized agent that allows the outside air to be blown toward the water surface.

In this way, even if the atomized drugs generated in real time on the water surface of the coma are collided by outside air and the particle size increases, they are re-comatable with the mixed water in the coma by their own weight, and only the atomized drugs that are not coma are exhausted. It can be discharged along the system.

Solutions for implementing another object of the present invention,

It is characterized by a sterilizer using an atomized agent configured to have a size of the air inlet supplied by the air supply means into the coma and to be smaller than the inlet of the exhaust system.

In this way, since an airflow that flows only in the outlet direction of the exhaust system due to the difference in pressure can be formed, there is no problem that the atomized drug flows back to the outside air inlet.

Solution means for implementing another object of the present invention,

It features a sterilizer using atomized drugs with a bottleneck in the exhaust system connected to the coma.

In this way, it is possible to continue to generate thrust that accelerates the flow of the airflow in the exhaust system as the airflow accelerates rapidly as it passes through the bottleneck.

The above-described exhaust system may further include an inclined pipe, and some sections may be composed of flexible hoses.

In this way, the condensed water condensed in the exhaust system by the inclined pipe can be collected again in the coma, as well as efficiently and effectively disinfecting the inside of a narrow space through a hose.

In the above-described exhaust system, in the configuration by connecting a plurality of pipes in order to configure the exhaust system, it is preferable that there is no connection or fastening element for lowering the airflow flow at the portion where the separated pipes are connected.

According to the present invention, even if the particles of the atomized drug generated in real time on the water surface are bound (heavier) by blowing outside air toward the water surface of the coma, the atomized drug is coma again into the coma immediately by its own weight, and does not become coma. Only discharged along the exhaust system.

In addition, in the present invention, since the size of the outside air inlet is configured to be smaller than the size of the inlet side of the exhaust system, the air pressure in the coma is always maintained larger than the air pressure in the exhaust system, so that the air flow always proceeds toward the outlet of the exhaust system.

In addition, in the present invention, since the airflow is accelerated when passing through the bottleneck section of the exhaust system, thrust acting toward the outlet of the exhaust system is continuously generated in the exhaust system.

In addition, since the present invention is not a method of injecting the vaporized drug through negative pressure, but a method of pushing out the atomized drug, it does not occur at all that the atomized drug is liquefied by the rotating blade as in a conventional blower. Therefore, it is possible to transfer the atomized drug to the end of the long flexible hose in a state of maximum preservation.

Taken together, the sterilizer of the present invention can intuitively and clearly see the scene where the drug is ejected from the end of the hose in an atomized state, so that the belief according to the disinfection effect can be clearly established, and the flexible hose In addition to being able to freely enter and exit places that are difficult to enter, it is possible to disinfect by spraying drugs to areas that are difficult to penetrate by thrust, as well as to farther places.

In addition, according to the present invention, since the condensed water condensed in the exhaust system falls into the coma along the inclined pipe and becomes coma, the amount of condensed water discharged to the exhaust system can be significantly reduced.

In addition, according to the present invention, since the sprayed drug evaporates after a few seconds, even a material vulnerable to moisture (or moisture) can be effectively sterilized.

It is to be understood that the presence or addition of elements or numbers, steps, actions, components, parts, or combinations thereof does not preclude in advance.

When a component is described as being connected, coupled or mounted to another component, it may be directly connected to or coupled to the other component, but other components may exist in the middle. Can be understood.

In the present specification, terms according to the elements according to the embodiments are used only to describe the illustrated embodiments, and are not limited thereto. In addition, expressions in the singular should be understood to include plural expressions unless the context clearly indicates otherwise.

In addition, it should be understood that all conditional terms and examples listed in the present specification are, in principle, only described so as to more easily explain and understand the concept of the present invention, and do not limit the illustrated embodiments.

Hereinafter, a preferred embodiment of a sterilizer using an atomized drug according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, FIG. 1 is a perspective view showing a sterilizer using an atomized drug according to the present invention, in which a sterilizer 100 has a door 100a that can be opened and closed on its front side. On the surface, an operation panel 110 equipped with an operation button (not shown in the drawing, hereinafter referred to as “operation unit”) and a charging module (hereinafter referred to as “billing unit 130, FIG. 5”) for charging are combined. And, it can be discharged to the end of the hose 113 (FIG.) in communication with the exhaust system 160 (FIG. 3) installed in the case 101 on the outer wall of one side of the case 101.

In FIG. 1, reference numeral 111 denotes a display window (hereinafter referred to as "display unit") in which selection information of the operation button and payment processing information of the billing unit 130 (Fig. 5) are displayed, and reference numeral 112 denotes the billing unit ( 130) is a card information reader and a receipt printer.

An example of employing the above-described billing unit 130 in the present invention is a card payment terminal capable of reading credit card, debit card, or exclusive card information and performing a card payment approval procedure through wired or wireless communication through the read information. Although the adoption is exemplarily described, the above-described billing unit may be configured by changing to a common currency (coin or bill) or other payment method (points, commuter pass) or mixing them.

In addition, the present invention uses a sterilizer capable of disinfecting the interior of a vehicle visiting the place when it is required by being installed in a place where vehicle access (or visit) is frequent, such as a parking lot, highway rest area, gas filling station, gas station, or self car wash. It will be described through an example, but it should be understood that this usage example is merely illustratively described to aid understanding of the present invention and does not limit the scope of use.

In this respect, it should be understood that the sterilizer 100 of the present invention can be changed to a shape and size that can carry or move the case 101 shown in FIG. 1. In this case, the arrangement position or shape of the operation panel 110 described above may be changed according to the shape of the case 101, and the above-described billing unit 130 may be omitted.

Referring to FIG. 2, FIG. 2 is a diagram showing a detailed configuration of the sterilizer installed in the case 101 when the above-described door 100a is opened.

The sterilizer 100 includes a liquid medicament supply unit, an atomization generation unit for atomizing the supplied drugs into ultrafine particles, and a discharge unit for discharging the atomized drugs to the outside of the sterilizer.

The above-described medicine supply unit is for independently transporting a medicine container 105a in which an undiluted disinfectant solution (hereinafter referred to as "disinfectant") is stored, a diluent container 105b containing a diluent for diluting the disinfectant, and the disinfectant and the diluent independently. It includes first and second fluid pumps 106a and 106b.

The medicine container 105a and the diluent container 105b described above are housed on the shelf (not shown in the drawing) of the machine room 101a so that they are visible when the door 100a is opened, and both containers 105a and 105b are separately It is desirable to configure them separately.

The reason is that if the disinfectant and the diluent are mixed in one bucket, if the disinfectant is not consumed for a long period of time, the weakening of the drug may gradually weaken (oxidize or disappear). Therefore, the disinfectant and the diluent are mixed only when the sterilizer 100 is operated. Because it is more useful to be able to.

Of course, if the drug is sufficiently consumed before the drug is weakened, or if the drug does not change even if time elapses, it may be mixed in one container. In this case, any one of the first or second fluid pumps 106a and 106b to be described later may be omitted.

The above-described medicine container 105a and the diluent container 105b may further include a water level sensor (not shown in the drawing).

The above-described both water level detection sensors independently sense when the water level of the above-described both or/and one side of the tank falls below the set water level, and transmits the sensing information to the controller 200 (FIG. 5).

The controller 200 controls (off) the first and/or second fluid pumps 106a, 106b in response to the sensing information above, or opens and closes the conduit of both tubes (not shown in the drawing) connected between the coma and the both. Each of the electronic valves (not shown in the drawing) may be provided so that both electronic valves may be proportionally controlled (off) by the controller 200.

The drawing shows an example of employing the first and/or second fluid pumps 106a and 106b.

Therefore, when the water level of both or either of the tanks falls below the set water level, the first and second fluid pumps 106a and 106b connected to the through tube are controlled (off) by the controller 200, and at the same time, the controller ( 200) alarms (outputs) related information on the display unit 111. According to the alarm information, it is enough to make up for the insufficient contents in both containers.

Therefore, the water level of the coma 102 is always maintained within a certain range, and in this state, the mixed water is atomized into ultrafine particles by the operation of the ultrasonic vibrator 109 (FIG. 3) to be described later.

Keeping the water level of the coma (102) constant is that if the water level of the mixed water is excessively high or, conversely, the amount of atomization generated by the ultrasonic vibrator 109 becomes unstable, the generation of atomization must be kept constant at all times. Because you need to do it.

In other words, if the amount of atomization generated compared to the air pressure supplied into the coma (102) is excessively large or, conversely, the amount of atomization is excessively small, the mixing ratio of the amount of outside air and the amount of atomization is not harmonious, and the number of condensation in the exhaust system 160 increases or the exhaust system ( The drug ejected to the end of 160) may be discharged in a liquefied state.

3 and 4, FIG. 3 is an enlarged view showing an enlarged view of the coma 102 shown in FIG. 2, and FIG. 4 is a cover 102c of the coma 102 shown in FIG. 3 It is a plan view as seen from the plane after removing.

The above-described atomization generator includes a coma 102 placed on a shelf in the machine room 101a (FIG. 2), and a plurality of ultrasonic vibrators 109 mounted on the bottom (or bottom) of the coma 102.

The above-described coma (102) is connected to the first and second fluid pumps (106a, 106b) and the tube (102a, Fig. 3) described above, and the water level sensing means (108) for detecting a water level, and an openable cover ( 102c) and an ultrasonic vibrator 109.

In addition, when the outside air is supplied into the coma (102), the size of the outside air inlet (104a) is configured to be smaller than the inlet (103b, FIGS. 3, 4) from which the exhaust system 160 starts, but the outside air inlet (104a) is It is preferable that the wind supplied through is blown toward the water surface of the mixed water. This will be described in more detail in the process of describing the discharge unit.

In addition, the above-described coma 102 includes a drain pipe (not shown in the drawing) for discharging the stored fluid. In the above-described drain pipe, an electromagnetic valve 102b that is opened by a control (on) of the controller 200 (FIG. 5) and a valve that is manually opened and closed (not shown in the drawing) are respectively coupled.

The above-described electronic valve 102b is controlled (on) by the above-described controller 200 by the sensing information of the water level detecting means 108 when the water level in the coma 102 is higher than the set range and reaches the normal water level. Then it is controlled (off) in the same way and closed.

The above-described ultrasonic vibrator 109 is attached to the bottom of the coma 102 in the form of an assembly and is controlled by a controller. When the vibrator 109 operates, the mixed water in the coma 102 is atomized into ultra-fine particles by micro-vibration.

As described above, since the amount of atomization varies depending on the level (or depth) of the mixed water, the sensing position of the above-described water level sensing means 108 is appropriately adjusted or the quantity of the ultrasonic vibrator 109 is appropriately adjusted in response to the water level. Need to adjust.

The above-described discharge unit includes a cover (102c, FIG. 3) coupled to be openable and closed on the coma (102), air supply means (104, FIGS. 2, 3) for supplying outside air into the coma (102), Doedoe coupled to communicate with the inside of the coma, and includes an exhaust system 160 extending out of the sterilizer (100). The cover (102c) is coupled to be airtight with the coma (102).

The above-described air supply means 104 encompasses means for maintaining the air pressure in the coma 102 higher than atmospheric pressure through air supply of outside air while being controlled by the controller 200 described above.

A specific example of the use of the air supply means 104 may be a sirocco fan or a propeller type blower, of which a sirocco fan type blower is more preferable. .

The aforementioned sirocco fan has a blade curved in a centrifugal direction, has a short length and has a large number of low pressure, can supply a large amount of outdoor air, and has less eddy currents because the outside air is sucked in the centrifugal direction, whereas the propeller rotates at high pressure. This is because the helical vortex is more severely generated by the wing, so that the atomized drug is more likely to be destroyed or liquefied.

It can be seen that when the above-described blowers are mounted on the sterilizer according to the present invention, and the operating state of each sterilizer is observed, the difference is clearly confirmed in the presence or absence of atomization of the ejected drug.

In FIG. 3, reference numeral 104a denotes an inlet through which outside air is introduced when the above-described air supply unit 104 is driven, and the outside air inlet 104a is the coma (102) so that the outside air is blown toward the water surface in the coma (102). It is preferable to provide it on the upper side of.

The reason is that, when the outside air is blown toward the water surface of the coma 102, even if the particles of the atomized drug are agglomerated with each other, they are coma again with the mixed water by their own weight, and only the atomized drug that is not mixed with the mixed water is exhausted. Compared to being discharged to (160), when the outside air inlet (104a) is installed on one side wall of the above-described coma (102), the wind collides on the wall of the opposite coma (102) or the air flow is swirling on the water surface by the inner wall. Is formed. This is because a larger amount and a larger amount of drugs (particles) are discharged into the exhaust system 160 while being combined.

Due to the above difference, in the latter case, the amount of condensed water in the exhaust system 160 is relatively increased, and the scene in which the atomized drug is ejected from the discharge port is not seen or seen relatively less.

More preferably, the ultrasonic vibrator 109 is disposed in the center of the coma 102 as shown in FIG. 4, and the outside air inlet 104a and the exhaust system inlet are disposed so as to be symmetrical to both sides based on this.

The above-described exhaust system 160 may be composed of a bottleneck section made of a bottleneck shape and a flexible hose 113, and the exhaust system 160 may further include an inclined section inclined at a predetermined angle.

The above-described hose 113 is better to maintain a constant flow of airflow that the entire section is configured with the same inner diameter.

The embodiment of the bottleneck section described above may be composed of a bottleneck tube 103 whose inner diameter gradually decreases from the inlet side to the outlet side, as shown in FIG. 3, and the inclined section installs the bottleneck tube 103 in an inclined manner. Alternatively, it may be an inclined pipe 103a coupled in an oblique direction between the bottleneck pipe 1030 and the hose 113.

Accordingly, since the airflow is accelerated when passing through the bottleneck 103 described above, a thrust force is generated in the exhaust system 160. Thus, the atomized drug can be sprayed (transferred) further by thrust.

In addition, since the condensed water condensed in the exhaust system 160 is collected into the coma 102 along the inclined pipe 103a, the discharge of condensed water can be significantly reduced.

On the other hand, in connecting the conduit constituting the above-described exhaust system 160, it is preferable to connect elements such as a conduit connecting member (or fastening member) that may interfere with the flow of air so that the inner diameter of the connecting portion is not exposed. Do.

5 is a block diagram showing a detailed configuration of the printed circuit board 200a on which the controller 200 constituting the control device of the indoor sterilizer according to the present invention is mounted, and the printed circuit board 200a is shown in FIGS. 1 and 2 As shown in the figure, it is coupled to the inner wall of the door 100, and on the front side of the door 100a, a display unit 111 electrically and circuitly connected to the above-described printed circuit board 200a, and an operation unit (drawing An operation panel 110 including a symbol (not abandoned) is coupled.

The operation panel 110 may further include a billing module (hereinafter referred to as “billing unit 130”) for charging a usage fee according to the use of the sterilizer 100.

The above-described billing unit 130 is a known credit card payment terminal or a commonly used coin or bill that reads credit card information and performs card payment approval through the wired/wireless communication module 140 (FIG. 2). A money payment device capable of charging using or may be configured by mixing them. Also, although not shown in the drawing, it includes a receipt printing device capable of printing the corresponding usage fee upon approval of the payment agency.

However, in the present invention, since the above-described billing unit 130 adopts the above-described known configuration, a detailed description thereof will be omitted.

The above-described sensing unit 201 includes a water level sensor (not shown in the drawing) installed in the medicine container 105a, the diluent container 105b and the coma 102 described above, and the water level sensing means 108 and the machine room 101a. It is a term collectively referring to the temperature sensor 131 for sensing temperature.

The display unit 111 includes a means for displaying selection information of an operation button, usage guide information for the sterilizer 100, and information related to card payment approval processing for charging a usage fee.

The controller 200 is a semiconductor microcomputer, in response to the sensing information of the sensing unit 201 and the manipulation of the operation unit (not shown in the drawing), the above-described ultrasonic vibrator 109, the first and second fluid pumps 106a, 106b, and It is pre-circuited and programmed to control the air supply means 104.

The present invention may further include a heating means for keeping warm to a certain temperature so that the inside of the machine room 101a is not frozen.

Preferred examples of the above heating means include a heater 132 (FIG. 2) installed in the machine room 101a and including a heating wire heated by a power source, and a temperature sensing sensor that senses the temperature of the machine room 101a in real time. It can be composed of 131.

That is, when the temperature measured by the temperature sensor 131 is lower than the set temperature, the heating means transmits the sensing information to the controller 200, and the controller 200 reaches the set temperature in the machine room 101a. The heating wire of the heater 132 (FIG. 2, reference numeral not indicated) is controlled (on) until it is controlled. In this way, it is possible to keep warm so that the inside of the machine room 101a does not freeze at sub-zero temperatures.

Referring to FIG. 6, FIG. 6 is a flow chart showing a control process according to the operation of the sterilizer according to the present invention, and the controller 200 performs the following process. Here, it is assumed that both water levels in the medicine container 105a and the diluent container 105b correspond to the set water level range, and the above-described billing unit 130 provides information on which the payment request is approved for the sterilizer usage fee.

The sterilizer 100 of the present invention may be started (a) by turning on an operation start button (not shown in the drawing). The controller 200 controls the sterilizer 100 at the same time as the operation start button is turned on.

At this time, if the usage fee is not normally paid by the billing unit 130, the controller 200 outputs (c) the sterilizer usage method and the contents related to the payment request to the display unit 111 for a predetermined period of time, and the sterilizer usage fee within the predetermined time. When the payment is completed, when the water level in the coma 102 falls within the set range, the controller 200 first controls the ultrasonic vibrator 109 (on) and then controls the air supply means 104 (on). .

In this process, when the water level in the coma (102) falls, the first and second fluid pumps (106a, 106b) are controlled (on), and the disinfectant and the diluent are mixed at a predetermined ratio until the water level reaches the set range. It is replenished in (102).

However, when the water level of the coma (102) is higher than the set water level, the controller 200 controls (on) the electronic valve (102b) until the water level is within an appropriate range, so that the water level of the coma (102) is properly maintained. .

The above water level adjustment function is performed while the sterilizer 100 is operating, in this case, the ultrasonic vibrator 109, the first and second fluid pumps 106a, 106b, and the air supply unit 104 are controlled by the controller 200. It is controlled so that it is not driven (off).

So, the sterilizer 100 of the present invention is continuously atomized by the predicted quantity only when the water level of the coma (102) falls within the appropriate (set) range, and the atomized drug is constantly supplied into the coma (102). It is discharged along the exhaust system 160 while being mixed with the outside air that is in a predicted ratio.

The time for atomization of the drug in the coma 102 and supply of external air to the inside thereof is preset by a timer (or relay circuit diagram not shown), but the ultrasonic vibrator 109 by a timer (or relay circuit) It is controlled so that the air supply means 104 is then stopped after is stopped.

In this way, by discharging all of the atomized drugs remaining in the exhaust system 160 to the outside, it is possible to minimize the aggregation of the residual drugs.

When the operation starts normally, the controller outputs and displays the set time in a countdown format, and when the set time is reached (g), after controlling (off) the ultrasonic vibrator 109, the air supply means 104 is controlled (off) ( h) to terminate the operation of the sterilizer 100.

In the above, preferred embodiments of the present invention have been exemplarily described with reference to the accompanying drawings, but if a person having ordinary knowledge in the technical field to which the present invention belongs, various application examples or modified examples can be implemented through the present invention. However, such an application example change example is to be disclosed in advance to be included in the technical idea and claims in the true meaning intended by the present inventors.
