Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art may easily implement the present invention. However, the present invention may be implemented in a number of different forms and is not limited to the embodiments described herein.

1 is a view showing a portable sterilizing gas generating device according to an embodiment of the present invention, Figure 2 is an exploded perspective view showing a coupling relationship of the portable sterilizing gas generating device according to an embodiment of the present invention. And Figure 3 is a view schematically showing a sterilizing gas generation process using a portable sterilizing gas generating device according to an embodiment of the present invention. 1 to 3, a portable sterilizing gas generator according to an embodiment of the present invention includes a first storage unit 120, a second storage unit 130, a separator 140, and an open guide unit 142. ), and a first solution supplied from the first storage unit 120 while the first storage unit 120 is separated from the second storage unit 130 and supported on one side of the open guide unit 142 The reaction between 120a and the second solution 130a stored in the second storage unit 130 generates a sterilizing gas. The portable sterilizing gas generator can be used immediately even in the absence of special equipment and external power supply. In addition, it is lightweight and compact for portability, so it can be used quickly in contaminated sites, and it is easy to operate and has high sterilization ability for anyone without specialized personnel.

The first storage unit 120 includes a storage container in which the first solution 120a is stored. Here, the first solution 120a may contain hydrochloric acid. A sealing part 126 provided below the first storage part 120 and sealedly coupled with the opening 140a of the separator 140 to maintain the sealing with the second storage part 130 may be further included. The sealing part 126 may be formed by including a gasket made of silicon or rubber. The sealing unit 126 functions to seal the opening 140a provided in the separator 140, and when the first storage unit 120 and the second storage unit 130 are combined, the second storage unit 130 Can be sealed. And it may further include a solution control valve 124 provided in the direction of the second storage unit 130 from the lower portion of the first storage unit 120 to control the discharge amount of the first solution (120a). The solution control valve 124 is a valve that controls the opening and closing of a drop hole in which the first solution 120a falls into the second storage unit 130. The dropping speed of the first solution 120a may be controlled by adjusting the size of the hole through which the first solution 120a flows through the solution control valve 124. If the first solution 120a falls into the second solution 130a at once, there is a possibility of an explosion due to a rapid reaction. Pressure increase due to sudden gas generation, or explosion due to sterilizing gas properties may occur. Therefore, it is necessary to control the hydrochloric acid to flow out little by little, but electronic control is difficult due to product characteristics. The solution control valve 124 may adjust the size of the hole through which hydrochloric acid flows, so that the hydrochloric acid flows out over 10 minutes when a predetermined amount of hydrochloric acid enters.

On the other hand, it may further include an air control valve 114 provided on one side of the upper portion of the first storage unit 120 to control the amount of air introduced from the outside. The air control valve 114 guides the inflow of external air so that the first solution 120a smoothly falls into the second storage unit 130 by a pore function of the first storage unit 120 and the solution control valve 124 can do. The first storage unit 120 stores hydrochloric acid therein, and normally, a sealing unit 126 provided at the lower portion covers the second storage unit 130 together with the separator 140. In addition, the first storage unit 120 is lifted and the second storage unit 130 positioned below is maintained in an open state for a chemical reaction operation that generates a sterilizing gas.

The second storage unit 130 includes a storage container in which a second solution 130a that reacts with the first solution 120a and generates a corresponding sterilizing gas is stored. Here, the second solution 130a may _{contain sodium chlorite (NaClO 2} ). The second storage unit 130 stores sodium chlorite, and the hydrochloric acid stored in the first storage unit 120 is mixed with sodium chlorite to form a space in which a chemical reaction occurs. In addition, the sterilizing gas may include _{chlorine dioxide (ClO 2} ) generated by a chemical reaction of hydrochloric acid as the first solution 120a and sodium chlorite as the second solution 130a. Chlorine dioxide has superior sterilization ability compared to other disinfectants, and can sterilize spore-type anthrax, which is particularly difficult to sterilize, so it has a sterilizing effect and versatility. It may further include a heating unit provided on the outer surface of the second storage unit 130 to discharge heat to maintain a reaction environment at a set temperature. The heating unit may include a heating wire capable of assisting a chemical reaction in a low temperature environment. Since the second storage unit 130 is provided with a low-power heating wire, a chemical reaction can be easily implemented even in an environment maintaining a set temperature. Meanwhile, a temperature switch 152 may be further included. The temperature switch 152 may function as a switch for operating the heating unit when the temperature is lower than a specific temperature using bimetal.

The separator 140 may be interposed between the first storage unit 120 and the second storage unit 130 to be coupled to the first storage unit 120 in a detachable relationship. The separator 140 may be formed in a disc shape, and a first storage unit 120 may be provided on the upper side, and a second storage unit 130 may be provided on the lower side. The separator 140 is interposed between the lower portion of the first storage unit 120 and the upper portion of the second storage unit 130, and an opening communicating the first storage unit 120 and the second storage unit 130 ( 140a) and may support the coupling of the first storage unit 120.

The open guide part 142 may be provided on the upper side of the separator 140 to support a state in which the first storage part 120 is separated from the second storage part 130. The open guide part 142 is a series of sterilizing gases such that the first solution 120a of the first storage unit 120 is mixed with the second solution 130a of the second storage unit 130 to generate a sterilizing gas through a chemical reaction. This is a part on which the first storage unit 120 is mounted before the device is operated. The first storage unit 120 must be lifted through the open guide unit 142 to open the second storage unit 130. When the first storage unit 120 is simply lifted, the first storage unit 120 descends again due to gravity and blocks the second storage unit 130. Accordingly, the open state of the first storage unit 120 may be fixedly supported by using the open guide unit 142. The first storage unit 120 is separated from the second storage unit 130 through the open guide unit 142 and supplied from the first storage unit 120 while being supported on one side of the open guide unit 142. The first solution 120a and the second solution 130a stored in the second storage unit 130 may react to generate a sterilizing gas. As the separator 140 and the open guide unit 142 are provided, the first storage unit 120 and the second storage unit 130 can be implemented in a variable storage structure. For example, when storing the first solution 120a and the second solution 130a, the first storage unit 120 and the second storage unit 130 may each be implemented in a sealed structure. And when the first solution (120a) of the first storage unit (120) and the second solution (130a) of the second storage unit (130) are mixed to generate a sterilizing gas that undergoes a chemical reaction, the first storage unit (120) And the second storage unit 130 may be implemented in an open structure. Since hydrochloric acid and chlorine dioxide are harmful to the human body, a structure that is isolated from the outside and a corrosion-resistant material are required. However, in the case of a design in which the outlet is separately made in a completely sealed type, it is not easy to make a structure that allows the discharge of sterilizing gas to be easily discharged due to the nature of a portable and limited space, and a powerful discharge device is required. Therefore, it is a closed type in the usual storage state, but has implemented a structure that is open only during operation.

Meanwhile, a case 10 including the first storage unit 120 and the second storage unit 130, the separator 140, and the open guide unit 142 may be further included. The case 10 functions as a skeleton and a protective device for a portable sterilizing gas generator, and may be made of MC nylon (Mono Cast Nylon) material having durability and corrosion resistance. Here, the case 10 is provided in a cylindrical shape with an open upper part, and an opening/closing cover 20 may be coupled to the upper part of the case 10. A lower cover 30 may be provided under the case 10. The lower cover 30 may be coupled to the case 10 in a separate coupling structure to support the internal parts. The lower cover 30 may be integrally coupled to the case 10 as necessary. The case 10 may be formed in a form in which related parts are mounted inside a cylindrical shape having a diameter of 15 cm and a length of 30 cm. If the sizes of the first storage unit 120, the second storage unit 130, and the case 10 are made too small, the amount and space of a solution that will cause a chemical reaction cannot be secured, and if they are made too large, it is difficult to carry. Therefore, it is important that it is easy to carry and has an appropriate size in consideration of chemical reactions.

And the portable sterilizing gas generating device formed in a light weight and small size is closely related to portability. The overall weight of the device may vary depending on the material and the degree of addition of additional components, but it can be formed to a weight of about 2.25kg, predicted from the experience of prototyping. And the concentration of the sterilizing gas generated by the portable sterilizing gas generator can be set to 4,000 ppm to 4,400 ppm when used ^{in a 1 m 3 space.} And it may further include a support portion 122 that is provided inside the case 10 to support the first storage unit 120 when the first storage unit 120 and the second storage unit 130 are combined and separated. . Further comprising a gas discharge unit 110 provided on the inner upper side of the case 10 for discharging the sterilizing gas generated by the reaction of the first solution 120a and the second solution 130a to the outside of the case 10 I can. The gas discharge unit 110 may include a fan, and may discharge sterilizing gas generated by a chemical reaction to the outside. And since the chlorine dioxide gas generated as the sterilizing gas is heavier than the air, the sterilizing gas can be quickly discharged to the outside by using the gas discharge unit 110.

The power supply unit 150 is provided under the case 10 to generate portable power, and is provided at one side of the separator 140, and is electrically connected to the power supply unit 150 through the switch unit 116, and from the power supply unit 150. The driving unit 112 driven by the supplied power, and one side is connected to the driving unit 112 and the other side is located inside the second storage unit 130 to rotate by receiving the rotational force of the driving unit 112 and rotate the first solution ( It may further include a stirring unit 132 for increasing the reaction efficiency by mixing 120a) and the second solution (130a). The power supply unit 150 may be formed in a compact size for easy portability including AA-size batteries. The power supply unit 150 introduces AA batteries for portability and convenient use, so that battery replacement is easy, and an operation method in which batteries are inserted only during operation is also possible. The driving unit 112 functions to operate the stirring unit 132. The switch unit 116 functions to electrically connect the power of the power supply unit 150 to the driving unit 112. The switch unit 116 may include a driving switch, a gas discharge switch, an air control switch, and a solution control switch. The switch unit 116 includes a corresponding switch for enabling the user to operate related driving parts, and may be designed so that a complicated operation process is omitted as much as possible. The stirring unit 132 may assist in mixing the first solution 120a and the second solution 130a so that the chemical reaction is smoothly performed. The portable sterilizing gas generator has a limited amount of chemical substances that can be reacted at one time. Therefore, it is possible to apply the stirring unit 132 that can increase the reaction efficiency.

As described above, the portable sterilizing gas generator according to the embodiment of the present invention can generate a predetermined amount of chlorine dioxide gas as a sterilizing gas with only a simple operation without needing to know a separate usage, and it is a size that can be transported by human hands. And because of its weight, it can be used quickly in contaminated sites. That is, the chlorine dioxide gas can be used in a field where power cannot be supplied, and in various environments, the number of uses can be increased or decreased according to the size of the space and can be applied in various forms. In addition, since it can be formed in a small size that is portable and portable, high effects can be expected in economic and industrial aspects.

A process of generating sterilizing gas using a portable sterilizing gas generator according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. First, it is assumed that hydrochloric acid, which is the first solution 120a, is stored in the first storage unit 120, and sodium chlorite, which is the second solution 130a, is stored in the second storage unit 130. In addition, it is assumed that the second storage unit 130 is closed in a sealed state so that external air cannot be introduced into the second storage unit 130. When the first solution 120a and the second solution 130a are stored, the first storage unit 120 for storing hydrochloric acid and the second storage unit 130 for storing sodium chlorite are closed from the outside. Keep it. Accordingly, hydrochloric acid is stored in the first storage unit 120 and sodium chlorite is stored in the second storage unit 130 (S310).

In this state, the opening and closing cover 20 closed on the upper portion of the case 10 is opened (S320). When the upper part of the case 10 is opened, the first storage unit 120 is lifted upward so that the second storage unit 130 is opened toward the outside. In addition, the first storage unit 120 is placed over the open guide unit 142 so that it does not descend toward the second storage unit 130 again by gravity (S330). By lifting the first storage unit 120 that covered the second storage unit 130, the second storage unit 130 is opened, and the first storage unit 120 is lifted to pass through the open guide unit 142 As a result, it can be kept open. Due to this, when sterilizing gas occurs, it can be discharged to the outside. If the sterilizing gas generation operation is implemented while the second storage unit 130 is not open, the gas may condense and explode.

The switch unit 116 is operated while the first storage unit 120 is supported over the open guide unit 142 (S340). For example, when the solution control valve switch is operated, the first solution 120a falls from the first storage unit 120 toward the second storage unit 130. The discharge amount of the first solution 120a may be set to gradually fall from the second solution 130a and fall over 10 minutes.

When the first solution 120a stored in the first storage unit 120 and the second solution 130a stored in the second storage unit 130 are mixed to start a chemical reaction, a sterilizing gas is generated. That is, when sodium chlorite stored in the second storage unit 130 and hydrochloric acid stored in the first storage unit 120 meet and start a chemical reaction, chlorine dioxide is generated. In this state, various chemical reaction auxiliary devices may be operated to assist the spraying of sterilizing gas. For example, the gas discharge unit 110 provided on the upper side of the first storage unit 120 may be driven so that the chlorine dioxide sterilizing gas can be easily discharged to the outside of the case 10. In addition, when the first solution 120a and the second solution 130a are mixed, the agitating unit 132 may operate to assist in smoothly performing a chemical reaction. In addition, since the heating wire is wound around the second storage unit 130, it is possible to assist a chemical reaction that may decrease efficiency when operating in a low temperature environment. With this operation, 1,000 ppm of sterilizing gas can be generated in 12 minutes in a ^{4 m 3 space.}

As described above, the portable sterilizing gas generator according to an embodiment of the present invention may be configured in a mechanically operated manner that does not require complicated control, and may generate a chlorine dioxide sterilizing gas of a certain concentration by utilizing an acid-chlorous acid chemical reaction. In addition, the portability is easy through miniaturization and weight reduction, enabling rapid mobility and field sterilization. And because the battery can be used, it can be used even in an environment where there is no separate external power source. In addition, the portable sterilizing gas generator does not generate chlorine disinfection by-products and generates chlorine dioxide gas of a fixed concentration, so that it can be sterilized by permeating evenly into the gaps of the contaminated site. And it can be used without power in the field, and it is easy to carry and use.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications can be made within the scope of the claims, the detailed description of the invention, and the accompanying drawings, and this is also It is natural to fall within the scope of the present invention.
