FIG. 2 is an exploded perspective view showing a configuration of a portable sterilizing water spray gun according to the present invention. 3 is a side perspective view showing in detail the internal structure of the portable sterilizing water spray gun according to the present invention.

1 to 3, the portable sterilizing water spray gun 1 according to the present invention includes a main body 100, a storage container 200, a lower structure 300 and a sterilizing water generating unit 400 .

The main body 100 has a spray nozzle 110 for spraying sterilizing water and a handle 120 having an operation lever 121. A pump 310 for sucking sterilizing water generated from the sterilizing water producing unit 400, a solenoid valve 320 for recovering the residual water in the main body 100, a controller 130 .

The main body 100 is supplied with sterilizing water generated by the sterilizing water generating unit 400 in the storage container 200 through the substructure 300 to enable the user to inject sterilizing water in a place where sterilization is required in real life .

The substructure 300 is coupled to the lower portion of the main body 100 and is accommodated in the interior of the storage container 200. At the lower end of the substructure 300, a sterilizing water generating unit 400 for generating sterilizing water is installed.

The lower structure 300 is fixed to the lower center of the main body 100 and accommodates therein a supply tube 321 for supplying the sterilized water generated from the sterilizing water generating unit 400 to the main body 100. The lower structure 300 includes a structure body 301 on which a sterilizing water generating unit 400 is installed and a structure cap 302 covering an upper portion of the structure body 301. The structure body 301 And the structure cap 302 may have at least one fastening hole for screwing. At least a portion of the structure cap 302 may be inserted into the main body 100. At the top of the structure cap 302, at least one hole connected to the solenoid valve 320 may be formed through a connection tube.

The storage container 200 is configured to receive the lower structure 300 and is coupled with the lower portion of the main body 100 to store raw water. The outer shape of the storage container 200 is not particularly limited and may be formed in various sizes and shapes. The material of the storage container 200 may be an opaque material, a transparent material, or a translucent material. However, when the material of the storage container 200 is opaque, it is impossible to observe the inside of the storage container 200 and the amount of the sterilizing water stored therein can not be measured. In addition, the operation of the substructure 300 and the sterilizing water generating unit 400 It is impossible to confirm whether or not the sterilized water has been produced in good quality. Therefore, it is preferable that the storage container 200 is made of transparent or semitransparent material.

The injection nozzle 110 of the main body 100 is formed in front of the main body 100 and has a trumpet shape so that sterilizing water can be injected at a place where sterilization is required. The injection nozzle 110 has a structure in which the injection angle of the sterilizing water injected when the injection nozzle 110 is rotated in the left or right direction is regulated so that the injection angle of the sterilizing water can be appropriately adjusted according to the use purpose.

The handle 120 of the main body 100 is formed at the rear of the main body 100 and includes an operating lever 121.

The handle 120 is detachably installed with a battery 122 to be charged by receiving power from an external power source. That is, according to the present invention, since the battery 122 is detachably installed in the handle 120, the battery 122 can be replaced with another battery 122 without waiting for charging. Since the present invention is free from the limitation of movement, the sterilizing water spray gun 1 can be easily used while being carried.

The controller 130 controls whether or not the sterilizing water spray gun 1 is powered and sets and controls the overall operation. The controller 130 may be formed on the upper side of the main body 100. The controller 130 may include a function for manually and automatically injecting sterilizing water and a function for causing the substructure 300 and the sterilizing water generating unit 400 to operate individually or simultaneously according to the use purpose.

The operation lever 121 can operate the pump 310 so that sterilizing water can be injected to the outside through the injection nozzle 110. For example, when the operation lever 121 is pressed, the pump 310 operates to suck sterilized water as shown in FIG. 4, and the sucked sterilized water is injected through the injection nozzle 110. Further, if the operating lever 121 is not pressed, the operation of the pump 310 is stopped, so that the suction of the sterilizing water and the discharge to the outside are stopped.

At this time, the sterilized water which is sucked in the main body 100 due to the operation of the pump 310 but not sprayed to the outside of the main body 100 can be left as the remaining water. Therefore, in the present invention, when the operation of the pump 310 is stopped, the solenoid valve 320 provided in the main body 100 is opened, and the remaining sterilized water not discharged to the outside is recovered to the storage container 200.

FIG. 5 is a side cross-sectional view showing a residual water discharge operation of the portable sterilizing water spray gun according to the present invention.

Referring to FIG. 5, one side of the solenoid valve 320 is connected to a transfer passage through which the sterilized water sucked from the pump 310 is supplied to the injection nozzle 110, and the other side thereof communicates with the storage container 200.

Specifically, the main body 100 may include a T-shaped pipe 140 in the passage through which sterile water sucked from the pump 310 is supplied to the injection nozzle 110. Here, the T-shaped pipe 140 is formed with connecting passages at one side, the other side, and the central portion, and the connecting passages may communicate with the pump 310, the injection nozzle 110, and the solenoid valve 320, respectively. That is, the portable sterilizing water spray gun 1 according to the embodiment includes a T-shaped pipe 140 for supplying sterilizing water sucked from the pump 310 to the spray nozzle 110 in the main body 100, A part of the connecting passage of the T-shaped pipe 140 is connected to the solenoid valve 320.

Therefore, when the solenoid valve 320 is opened, the remaining sterilizing water left in the main body 100 flows to the solenoid valve 320 through the T-shaped pipe 140, and the remaining sterilization water supplied to the solenoid valve 320 The water is recovered to the storage container 200.

On the other hand, the principle of recovery of the remaining sterilized water according to the operation of the solenoid valve 320 is as follows. The injection nozzle 110 is formed to have a small diameter for spraying, so that the internal pressure around the injection nozzle 110 increases when the pump 310 is operated. 5, when the solenoid valve 320 is opened after the operation of the pump 310 is stopped, the residual sterilizing water which is not sprayed outside due to the internal pressure around the injection nozzle 110 Is collected in the storage container 200 as it moves toward the solenoid valve 320.

The opening and closing operation of the solenoid valve 320 may be based on the operation of the operating lever 121. For example, when the operation lever 121 is pressed, the solenoid valve 320 is closed so that the sterilized water sucked due to the operation of the pump 310 is ejected to the outside. When the operating lever 121 is not pressed, the solenoid valve 320 is opened and the remaining sterilizing water that has not been spouted outside is recovered to the storage container 200 through the solenoid valve 320.

The solenoid valve 320 may be a solenoid valve that is electrically connected to the operating lever 121 to automatically close the valve due to the weight of the flange when the flange is raised and the valve is opened and the electricity is cut off when electricity is supplied. The position and structure of the solenoid valve 320 are not particularly limited and may include all of those well known in the art.

Meanwhile, when the sterilizing water generating unit 400 operates to generate sterilizing water, hydrogen gas is generated in the process. If the generated hydrogen gas is accumulated in the storage container 200, it may cause a burst or explosion have. Accordingly, the portable sterilizing water spray gun according to the embodiment of the present invention may include a discharge structure for discharging the hydrogen gas accumulated inside the storage container 200 to the outside.

Hereinafter, a discharge structure and a method for discharging hydrogen gas to the outside in a portable sterilizing water spray gun according to an embodiment of the present invention will be described in detail.

6 is a side cross-sectional view showing a hydrogen gas discharging operation of the portable sterilizing water spray gun according to the present invention. 7 is a perspective view of the portable sanitizing spray gun according to the present invention as viewed from the lower side.

The gas discharge pipe 323 is connected to the second gas discharge hole 322b communicated with the outside through the gas discharge tube. Therefore, the hydrogen gas accumulated in the storage container 200 is discharged to the outside via the first gas discharge hole 322a, the gas discharge pipe 323, and the second gas discharge hole 322b.

Considering the practical use of the portable sterilizing water spray gun according to the present invention, the user often tilts the spray nozzle 110 downward to spray the sterilizing water, so that the raw water stored in the storage container 200 is sprayed to the spray nozzle 110) is located in the front direction. Accordingly, in the present invention, the first gas discharge hole 322a is formed in the rearward direction rather than the forward direction in which the injection nozzle 110 is located, and the second gas discharge hole 322b is formed in the structure Can be formed in the lateral direction of the body (301). Alternatively, the first gas discharge hole 322a may be formed on the rear surface of the structure body 301, and the second gas discharge hole 322b may be formed on the front surface of the structure body 301. [ In the present invention, when the raw water contained in the storage container 200 is biased toward the front or back direction when the apparatus of the present invention is used, the first gas discharge hole 322a is easy to discharge hydrogen gas.

7, a sterilizing water discharge hole 333 through which sterilizing water is recovered by opening the solenoid valve 320 may be further formed on a part of the upper surface of the structure body 301. [ Here, the sterilizing water discharge hole 333 may be positioned adjacent to the first gas discharge hole 322a. That is, according to the present invention, the sterilizing water discharge hole 333 is formed in the rearward direction adjacent to the handle 120 like the first gas discharge hole 322a so that even if the raw water contained in the storage container 200 is biased toward the front , And the sterilized water can be easily recovered.

Hereinafter, the structure of the sterilizing water producing unit 400 will be described in more detail.

8 to 10, a sterilizing water generating unit 400 is fixedly installed on the lower side of the lower structure 300. The sterilizing water generating unit 400 is connected to the lighting module 420 and the electrode And the module 430 are integrally connected. That is, the sterilizing water generating unit 400 has a structure in which the illumination module 420 and the electrode module 430 are integrally connected by the electrode rod 410, thereby supplying illumination light inside the storage container 200, It is possible to generate sterilized water by underwater discharge.

The electrode rod 410 is provided with electric power from the main body 100 and is formed into a rod shape having a predetermined length. The electrode rod 410 is connected to the lighting module 420 and the electrode module 420 according to a control signal of the controller 130. [ And is electrically connected to the controller 130 so as to separately or simultaneously supply power to the controller 430. If the electrode rod 410 is not connected to the lighting module 420 and the electrode module 430, the lighting module 420 and the electrode module 430 are connected to the controller 130 separately It is preferable that the lighting module 420 and the electrode module 430 are integrally connected to each other by the electrode rod 410 because the internal structure of the lighting module 420 and the electrode module 430 may be complicated, .

The illumination module 420 is provided with a PCB substrate 422 having a light emitting diode inside the lamp case 421 to provide illumination light inside the storage container 200.

In this case, since the PCB substrate 422 causes a failure of the device when it is immersed in water, in order to have a waterproof and moisture-proof structure, a PCB substrate 422 is mounted inside the lamp case 421 and a transparent epoxy Molding process. That is, the PCB substrate 422 having a light emitting diode is molded with a transparent epoxy so that the illumination light can be projected outside the lamp case 421.

In addition, the light emitting diode mounted on the PCB substrate 422 may be composed of various lamps including a fluorescent lamp. However, in order to provide suitable illumination light according to the setting and control of the controller 130, It is preferable to have a diode. The lamp case 421 is connected to the inlet tube 321 of the lower structure 300 so as to suck sterilized water generated by the underwater discharge of the raw water due to the difference in air pressure caused by the operation of the pump 310 It is preferable that the tube 421a is formed to be protruded, and furthermore, it is preferable that the tube 421 is made of transparent or semitransparent material so that the light provided by the light emitting diode can be projected to the outside of the lamp case 421. Therefore, the operating state of the portable sterilizing water spray gun 1 can be easily confirmed by the color of the illumination light provided inside the storage container 200.

11 is a plan view showing the structure of an inflow pipe according to the present invention. 12 is a perspective view showing the structure of an inflow pipe according to the present invention.

11 and 12, the end of the inflow pipe 421a may have a structure in which the filter 423 is inserted. That is, the present invention may include a filter 423 inserted into the end of the inflow pipe 421a. The filter 423 functions to filter the foreign substances contained in the sterilized water to be sucked through the filter 423 when the sterilized water is sucked through the inflow pipe 421a. To this end, the filter 423 may be comprised of a nonwoven fabric, a cotton or a fibrous foam. At the same time, the inlet pipe 421a may be opened at least partially so that the sterilizing water can be easily introduced into the filter 423. For example, the inlet pipe 421a may be configured such that four sides are open as shown in Figs. 11 and 12. Fig. Therefore, the cross section of the inlet pipe 421a may have a cross shape (+). In the present invention, since the side surface 421b of the inflow pipe 421a is opened, the path for introducing sterilizing water into the filter 423 is increased, the sterilizing water is easily sucked, and the sterilizing water is easily filtered.

On the other hand, the electrode module 430 includes at least one pair of electrode plates 431 having a cathode and an anode. By disassembling the water molecules filled in the storage container 200 using the principle of underwater discharge, Make sterile water. That is, a plasma discharge is generated in water using an underwater discharge which makes water into an underwater plasma ion state, and various anions (O-, O3-, OH-, HOCl and H2O2) , Bacteria and the like.

The electrode module 430 includes an electrode structure including an upper electrode plate 403 and a lower electrode plate 404 facing each other, an electrode separator plate 405 provided between the upper electrode plate and the lower electrode plate, And pressure supporting portions 401 and 402 for pressing the electrode structure on both sides.

The pair of electrode plates 403 and 404 includes an upper electrode plate 403 and a lower electrode plate 404 facing each other. The upper electrode plate 403 is located above the lower electrode plate 404. The upper electrode plate 403 is formed with a plurality of slits in a specific direction, for example, the x-axis direction. The lower electrode plate 404 is formed with a plurality of slits in a specific direction, for example, a y-axis direction perpendicular to the x-axis direction. Accordingly, the slits formed in the upper electrode plate 403 and the slits formed in the lower electrode plate 404 may be arranged to have a predetermined angle, for example, 90 degrees. Water introduced into the electrode module 430 is discharged underwater through a plurality of slits. The width of the plurality of slits is not particularly limited, but it is preferable that the gap between the adjacent slits and the width of the slit are designed to be the same in consideration of rigidity of the electrode plate and flow rate of water. Each of the upper electrode plate 403 and the lower electrode plate 404 has an extension for applying power. According to another embodiment, the upper electrode plate 403 and the lower electrode plate 404 each have at least one hole formed in a rim of the upper electrode plate 403 and the lower electrode plate 404, and an electrode for applying power to each electrode plate is inserted into at least one hole, It is possible. The upper electrode plate 403 and the lower electrode plate 404 are made of a metal that is harmless to the human body and excellent in corrosion resistance, heat resistance, and mechanical tensile strength. For example, the upper electrode plate 403 and the lower electrode plate 404 are made of titanium and then coated or vapor-deposited with a platinum group metal such as platinum, iridium, palladium, osmium, or ruthenium. According to another embodiment, the upper electrode plate 403 and the lower electrode plate 404 can be manufactured by depositing titanium on a single plate and then coating or vapor-depositing the same using a platinum group material. Such electrode plates 403 and 404 may include any type known in the art, for example, those disclosed in Korean Patent No. 10-0927445 and / or Korean Utility Model Registration No. 20-0419542 .

The pressing supports 401 and 402 are located above and below the electrode plates 403 and 404, respectively. Specifically, the pressing supports 401 and 402 include a first pressing support 401 located above the upper electrode plate 403 and a second pressing support 402 located below the lower electrode plate 404. The first pressing support portion 401 may be configured to cover at least a portion of the upper electrode plate 403 at an upper portion of the upper electrode plate 403. [ The second pressing support 402 may be configured to support at least a portion of the lower electrode plate 404 in the lower portion of the lower electrode plate 404. The pressing supports 401 and 402 prevent the electrode plates 403 and 404 from flowing and press the electrode plates 403 and 404 on both sides. Accordingly, the upper electrode plate 403 and the lower electrode plate 404 are more closely adhered to the electrode separator 405 located therebetween, and as a result, the reaction rate for generating ionized water, hydrogen gas, and the like can be further increased .

According to one embodiment, at least one of the first pressing portion 401 and the second pressing portion 402 has a convex shape toward the electrode structure. For example, FIG. 5 shows a cross-sectional view schematically showing the pressure supporting portions 401 and 402. The first pressing supporting portion 401 has a convex shape at the center thereof and a second pressing support portion 402 Has a convex shape at the center portion. The center pressurizing support portions 401 and 402 which are convex in the middle as described above press the upper electrode plate 403 and the lower electrode plate 404 further can do. According to another embodiment, only one of the pressing supports 401 and 402 can be convex in the direction of the electrode plate structures 403 and 404. For example, only the first pressurizing support 401 among the pressurizing supports 401 and 402 may be convex downward, or only the second pressurizing support 402 may be convex.

In addition, as described above, the upper electrode plate 403 and the lower electrode plate 404 may be overlapped to form a plurality of slits formed therein so as to intersect with each other to form a hole. In addition, the present invention is characterized in that the second pressing support portion 402 is formed of a flat plate having a through portion corresponding to the hole. That is, this type of pressing support portion can be pressed against the electrode plate as much as possible without interfering with ions or water passing through the electrode plate. It is preferable that the pressing support portion is a second pressing support portion 402 provided below the lower electrode plate 404 in the present invention. In the present invention, it is more preferable to minimize the oxygen ions moving below the lower electrode plate 404 to minimize the discharge of water.

The inventors of the present invention have tested the pressing support portion formed of a flat plate having a through portion corresponding to the hole by applying it to both of the first and second pressing support portions 401 and 402. Therefore, the production efficiency of ionized water and hydrogen gas can be maximized. However, in the case of the first pressing support portion 401, the discharge speed of the generated hydrogen gas is somewhat delayed. Accordingly, the first pressing support portion 401 provided on the upper electrode plate 403 is designed so that the hydrogen gas can pass easily It is more desirable to do so.

The first pressing support portion 401 includes a circular outer supporting portion 507 having a first diameter to support the outer periphery of the upper electrode plate 403, A circular center support portion 505 having a second diameter smaller than the first diameter and supporting connection portions 501 and 503 for connecting the outer support portion and the center support portion.

Any one of the pressure supporting portions 401 and 402, for example, the first pressing supporting portion 401, has an outer supporting portion 507 configured in the form of a first donut having a first diameter and an opening at the center, A center support portion 505 which is formed in the shape of a second donut having a center and is opened inside the outer support portion 507 and connection supports 501 and 503 which connect the outer support 507 and the center support 505, . The connection support portions 501 and 503 include first and second connection support portions 501 and 503 intersecting with each other with respect to the center support portion 505. The first and second connection supports 501 and 503 may intersect in a direction perpendicular to each other. As such, the first pressure supporting portion 401 of the present invention can more easily discharge the hydrogen gas. On the other hand, the central supporting portion 505 constituting the first pressing support portion 401 may be convex downward or may be designed to have a relatively low height as compared with the outer supporting portion 507. This is for further pressing the electrode plates 403 and 404 as described in Fig.

On the other hand, the center support portion 505 has a relatively downward convex shape, so that the upper electrode plate 403 and the lower electrode plate 404 can be further compressed. Specifically, the height of the center support portion 505 and the height of the outer support portion 507 may be designed to be different from each other. For example, the central support portion 505 has a relatively convex shape, so that the height of the lower surface of the central support portion 505 may be lower than the height of the lower surface of the outer support portion 507.

According to one embodiment, the first and second connection supports 501 and 503 may be disposed parallel to or perpendicular to the slits of the upper electrode plate 403 or the lower electrode plate 404. For example, the first connection support portion 501 may be positioned parallel to the slit of the upper electrode plate 403 and perpendicular to the slit of the lower electrode plate 404. Alternatively, the first connection supporting portion 501 may be positioned perpendicular to the slit of the upper electrode plate 403 and may be positioned in parallel with the slit of the lower electrode plate 404.

The first and second connection supports 501 and 503 may be positioned so as to overlap with at least one of the plurality of electrode bridges constituting the upper electrode plate 403. The plurality of electrode bridges are arranged in one direction with a specific interval to form slits. One of the first and second connection supporting portions 501 and 503 may be positioned to overlap at least one of the electrode bridges of the upper electrode plate 403. [ In this case, it is possible to minimize the inhibition of the movement of the hydrogen gas by the connection supporting portions 501 and 503.

Although the present invention has been shown and described with respect to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims It will be apparent to those skilled in the art.
