Description

[Technical field]

[0001] The present invention relates to a disinfectant and insecticide sprayer, and more particularly to a disinfectant and insecticide sprayer that has a disinfectant bubble water sprayer and an insecticide liquid sprayer that are independent of each other and are constructed as an integrated unit. [Background technology]

[0002] Disinfectants such as insecticides and bactericides are supplied to the target material by a nozzle spraying device that sprays them in liquid form through a spray nozzle, a mist disinfecting device that sprays them in mist form together with combustion gas, or a vaporizing disinfecting device that vaporizes the disinfectant and supplies it in a fumigation state.

[0003] The nozzle spray device or the fog disinfection device is operated while worn by a person or while attached to a vehicle or the like.

[0004] However, since the vaporizing disinfection device vaporizes the disinfectant by vibration, the structure is relatively complicated, vibration is inevitably generated, and it is difficult to wear or move around.

[0005] Recently, there has been a growing need for sprayers that can be easily prepared and replaced with sterilized water for sterilization, and that can be used in environments that require not only sterilization but also insecticide, such as food factories and large restaurants. Summary of the Invention [Problem to be solved by the invention]

[0006] An object of the present invention is to provide a sterilization and insecticide sprayer that can be manufactured into a compact structure and is easy to transport and install. [Means for solving the problem]

[0007] In order to achieve the above object, a sterilization and insecticidal sprayer according to one embodiment of the present invention includes a sterilizing water container for storing sterilizing water, an insecticidal liquid container for storing an insecticidal liquid, a three-way valve for selectively switching compressed air to spray sterilizing water from the sterilizing water container or to supply the sterilizing liquid container to the insecticidal liquid container, a vibration generator located in the insecticidal liquid container and generating vibrations by compressed air supplied from the compressor and a piezoelectric element, a piezoelectric element located on an upper part of the vibration generator, an inner tube for transmitting compressed air through an axial center of the vibration generator in an up and down direction, a horn body located below the piezoelectric element and accommodating the inner tube, a horn body groove penetrating the horn body from the inner tube, a front A circulation chamber is formed in the space between the horn body and the outer part of the vibration generator. The compressed air that has passed from the inner tube through the horn body groove and horn body hole of the horn body circulates along the circulation chamber, and N wing diaphragms are fixed to one side of N side surfaces formed in the outer hole of the vibration generator and block the N side surfaces, and N bottom diaphragms block N fan-shaped bottom surfaces formed in the bottom hole of the vibration generator. The compressed air in the circulation chamber passes through the outer hole and collides with the N wing diaphragms and the bottom diaphragm, and a horn body buffer part 222B having a shape that narrows as it goes from the horn body hole to the bottom of the horn body is formed.

[0008] In addition, each of the N wing diaphragms is a rectangular plate having one side fixed to one side of the outer portion and the other side extending from the one side of the outer portion.

[0009] In addition, each of the N bottom diaphragms is a triangular plate having one side fixed to the bottom center of the vibration generator and the other side extending from the bottom center to one side of the outer portion.

[0010] In addition, the N bottom vibration plates are fixed at the bottom center by a bottom fastening part, and when the bottom fastening part is removed, the inside of the vibration generator can be purged by compressed air.

[0011] In addition, one side of the pesticide container is fixed to a compressed air line connected to the top of the pesticide container, and the other side of the pesticide container is fixed at a predetermined distance from the bottom of the pesticide container.

[0012] In addition, the horn body groove may be disk-shaped, with a curved surface formed along the circumference in the radial direction and with a constant height, or may be a conical horn body groove with a conical cross section and with a curved surface formed along the circumference from the apex to the end of the generating line in the radial direction. Effect of the Invention

[0013] The disinfecting and insecticidal sprayer of the present invention has an effect of reducing the overall size by using a compressor and a three-way valve that can be commonly used for the disinfecting bubble water sprayer and the insecticidal liquid sprayer.

[0014] In addition, by forming protrusions on the cathode plate of the electrode module of the sterilizing bubble water sprayer, it is possible to further expand the plasma reaction in the electrode module.

[0015] In addition, the horn body buffer part 222B is formed so that the width becomes narrower from the hole of the horn body of the insecticide liquid sprayer toward the bottom of the horn body, thereby reducing vibration and impact caused by compressed air.

[0016] In addition, the size of vaporized insecticide liquid can be further reduced by forming a blade vibrating part on the side of the vibration generator of the insecticide liquid sprayer and a bottom vibrating part on the bottom.

[0017] In addition, when dismantling the bottom fastener 244, it is possible to purge the inside of the vibration generator of any contamination or residue using compressed air.

[0018] In addition, one side is fixed to a compressed air line connected to the upper part of the insecticide liquid container, and the other side is fixed at a predetermined distance from the bottom surface of the insecticide liquid container, and for this purpose, the bottom surface of the vibration generator may be formed with legs for fixing the vibration generator toward the bottom surface of the insecticide liquid container.

[0020] Hereinafter, a disinfecting and insect killing sprayer according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0021] A cylindrical sterilizing bubble water sprayer and an insecticide liquid sprayer are respectively positioned inside the external housing. Both the sterilizing bubble water sprayer and the insecticide liquid sprayer are operated by compressed air supplied from the outside. The sterilizing and insecticide sprayers of the present invention are generally referred to as a sterilizing bubble water sprayer and an insecticide sprayer, respectively, and sterilizing water (salt + H2O2, or tap water) is used as the sterilizing bubble water (HOCL, OH-, O3). FIG. 1 shows a cylindrical sterilizing water container 100 and an insecticide liquid container 200, respectively, inside the sterilizing and insecticide sprayer of the present invention. The containers not only serve as containers or tanks for storing the sterilizing water and the insecticide liquid, but also include the space including the path where the reaction takes place.

[0022] First, the sterilizing bubble water sprayer fills the sterilizing water container 100 with tap water or sterilizing water containing salt and H2O2 (hereinafter referred to as sterilizing water) through the sterilizing water inlet 110, and measures the water level using a level sensor. The sterilizing water passes through the electrode module 130 from the bottom of the sterilizing water container 100 by the pump 120 installed separately from the sterilizing water container, and is finally sprayed to the outside as hypochlorous acid water.

[0023] Outside air is supplied to the disinfection and insecticide sprayer by the compressor 20, and is selected and supplied to either the disinfection bubble water sprayer or the insecticide sprayer by the three-way valve 40. At this time, the air pressure is measured by the pressure gauge 30.

[0024] The injection of the sterilizing water is performed by adjusting the three-way valve when the insecticide sprayer is not in operation. When the sterilizing water that has passed through the electrode module 130 is discharged, compressed air is supplied through a separate parallel line (the line on the left side of the pressure gauge) so that the pumped sterilizing water and compressed air are injected to the outside together through the two-fluid injection nozzle.

[0025] The insecticide liquid container 200 in Fig. 1 is a cylindrical housing containing a vibration generator 200 that receives compressed air from the outside and vaporizes the insecticide liquid. External air compressed by a compressor is selected by a three-way valve 40, and the compressed air flows into the insecticide liquid container. In this specification, vaporization means a state in which liquid is atomized to a size that can be suspended in the air.

[0026] That is, a three-way valve 40 is provided as a solenoid valve in a compressed air supply pipe connected to the insecticide liquid container 200 by the compressor 20 .

[0027] At this time, the pressure is checked with a pressure gauge 30, and a safety pin 60 is installed against overpressure for safety in case of failure. Air passes through a heater tube 70 for heating and flows into an insecticide liquid container 200 via a check valve 80. An insecticide liquid solution is injected through an insecticide liquid inlet 90 and finally discharged through an outlet 92.

[0028] 2, the electrode module is of a pressurized flow radial stirring type, and has a structure in which sterilizing water supplied by a pump from a sterilizing water container can flow through the electrode assembly 130 via an electrode assembly inlet 113 connected to the electrode assembly 130 and an electrode assembly outlet 114. For this purpose, the electrode module may have a structure including radial flow paths 140 along the stacking surface.

[0029] The electrode module 130 according to FIGS. 2a and 2d may include a first electrode assembly 131, a second electrode assembly 132, a third electrode assembly 133 and a fourth electrode assembly 134.

[0030] 2b and 2d are diagrams showing the flow directions of sterilizing water forming radial flows in the electrode assemblies in the electrode module 130, and are arranged alternately with each other in the first, second, third, and fourth electrode assemblies, respectively.

[0031] The first electrode assembly 131 may be disposed at the outermost position facing the sterilizing water inlet 110, and may have a structure in which an anode plate 161 is attached to the surface facing the sterilizing water supplied from the sterilizing water inlet 110, and a flow path 140 is formed in the center direction on the other side.

[0032] The first electrode assembly 131 may have a structure in which the anode plate 161 is mounted on one side of an electrode mounting body 135-1 having a disc-shaped structure with radial spokes formed thereon when viewed from the side.

[0033] A through hole D1 may be formed at the center of the electrode mounting body 135-1. At this time, a through hole D2 may also be formed at the center of the negative electrode plate 162 mounted on the second electrode assembly 132, and in this case, it is preferable that the inner diameter of the through hole D2 formed in the negative electrode plate 162 is larger than the inner diameter of the through hole D1 formed in the electrode mounting body 135-1 by a predetermined size. Sterilizing water can flow through the through holes D1 and D2 structured as above.

[0034] The inlet / outlet passage 142-2 formed in the second electrode mounting body 135-2 is preferably formed at a position corresponding to the through hole 137 formed in the electrode mounting body 135-1 of the first electrode assembly 131.

[0035] A mesh member 161-1 made of a conductive material is attached to one side of the anode plate 161 to more effectively supply electric current to the sterilizing water flowing in.

[0036] The second electrode assembly 132 may be stacked adjacent to the first electrode assembly 131, with a cathode plate 162 attached to the surface facing the first electrode assembly 131, a flow path 140 formed in the center direction on the other side, and a flow path 143 formed in the center that penetrates to the other side.

[0037] The third electrode assembly 133 may be stacked adjacent to the second electrode assembly 132, with an anode plate 163 attached to the surface facing the second electrode assembly 132, a radial flow path 140 formed from the center, and a cathode plate 164 attached to the other side.

[0038] The fourth electrode assembly 134 may be stacked adjacent to the third electrode assembly 133, and may have a radial flow path 140 formed on the surface facing the third electrode assembly 133, and a positive electrode plate 165 attached to the other side.

[0039] In addition, it is preferable that an inlet / outlet channel 142 through which sterilizing water can be injected or discharged is formed between the electrode assemblies 130 at a step formed by stacking the electrode assemblies 130 having different outer diameters.

[0040] The sterilizing water flowing along the radial flow paths 140 formed in the electrode module 130 repeatedly converges and diffuses toward the center of the electrode assembly 130, so that an electric current is effectively supplied to the sterilizing water, thereby performing an effective electrolysis action.

[0041] By disposing the electrode plates 161, 162, 163, 164 of the anode plate or cathode plate at specific positions in each electrode assembly 131, 132, 133, 134, it is possible to effectively supply current to the sterilizing water flowing in various directions to perform electrolysis, and when water in which sodium chloride is dissolved is supplied as the sterilizing water, it is possible to effectively generate hypochlorous acid water and provide an electrode module optimization device that can effectively perform the role of reforming the sterilizing water.

[0042] Of the electrode plates 161, 162, 163, and 164 attached to the first electrode assembly 131, the second electrode assembly 132, the third electrode assembly 133, and the fourth electrode assembly 134, it is preferable that the electrode plates 161-162, 162-163, 163-164, and 164-165 arranged adjacent to each other have different polarities.

[0043] The outer circumferential surfaces of the second electrode assembly 132 and the fourth electrode assembly 134 are preferably formed with an outer diameter that corresponds to the storage space of the housing 110. In addition, the outer circumferential surfaces of the first electrode assembly 131 and the third electrode assembly 133 are preferably formed with an outer diameter that is smaller than the outer diameter of the second electrode assembly 132 or the fourth electrode assembly 134 by a predetermined length.

[0044] The third electrode assembly 133 and the fourth electrode assembly 134 may each be attached with a power supply terminal 150 of a different polarity protruding a predetermined length from one side of the housing 110. In this case, the first electrode assembly 131 may receive power from the power supply terminal 151 attached to the fourth electrode assembly 134, and the second electrode assembly 132 may receive power from the power supply terminal 152 attached to the third electrode assembly 133.

[0045] The nut 154 is fastened to the power supply terminals 151, 152 to join the electrode modules together.

[0046] The structure of each of the electrode assemblies 131, 132, 133, and 134 will be described in more detail below.

[0047] Each of the electrode assemblies 130 (131, 132, 133, 134) may include an electrode mounting body 135 (135-1, 135-2, 135-3, 135-4) having a specific structure and an electrode plate 160 (161, 161-1, 162, 163, 164).

[0048] Specifically, the electrode mounting body 135 (135-1, 135-2, 135-3, 135-4) is preferably a disk-shaped structure formed with a predetermined outer diameter, with an electrode plate mounting groove 136 formed by recessing the center of the disk with a predetermined outer diameter. In this case, the electrode plate 160 (161, 161-1, 162, 163, 164) can be stably mounted in the electrode plate mounting groove 136.

[0049] In addition, the radial flow paths 140 formed in the electrode mounting body 135 preferably have a through structure that penetrates and connects one side of the electrode mounting body 135 on which the electrode plate 160 is mounted to the other side. In this case, an electric current can be effectively supplied to the sterilizing water flowing along the radial flow paths 140, and the generation efficiency of the electrolyzed gas can be significantly improved.

[0050] The radial flow path 140 may have a structure including both a radial structure and a bent structure, in which case a large vortex can be formed in the flow of the sterilizing water, and an electric current can be effectively supplied to the sterilizing water, thereby maximizing the electrolysis action.

[0051] When the electrode assembly 130 has a polygonal structure when viewed in a plane, it is preferable that the receiving space of the housing 110 is also formed to have a corresponding structure.

[0052] The electrode assembly 130 may have a disk-like structure having an outer diameter corresponding to the storage space of the housing 110, and another electrode assembly 130 may have a disk-like structure having an outer diameter smaller than that of the first electrode assembly 130 by a predetermined length.

[0053] At this time, it is preferable that an inlet / outlet channel 142 through which sterilizing water can be injected or discharged is formed between the electrode assemblies 130 at a step portion formed by stacking the electrode assemblies 130 having different outer diameters.

[0054] Meanwhile, FIG. 3 is a diagram conceptually illustrating the electrode module of FIG. 2. The anode plate and the cathode plate are spaced apart from each other by the electrode housing, and electrolysis or plasma reaction occurs between the anode plate and the cathode plate. The electrode housing has radial flow paths for the movement of sterilizing water. The electrolysis or plasma reaction between the anode plate and the cathode plate can be performed by forming electrode protrusions for multiple plasma reactions on the surfaces where the anode plate and the cathode plate face each other, particularly on the cathode plate, to avoid the area where the electrolysis or plasma reaction is interfered with by the radial flow paths. A plurality of combinations of the anode plate, the cathode plate, and the electrode housing present therebetween may be formed, thereby forming the electrode protrusions formed on the cathode plate. The electrode protrusions may be formed in a plurality of rows at a predetermined interval in the radial direction, with a narrow upper and wide lower shape, without being interfered with by the radial flow paths. DC or AC voltage may be applied for electrolysis or plasma reaction.

[0055] A block diagram showing an electrochemical reaction system including an electrode module optimization device according to one embodiment of the present invention is shown.

[0056] The control unit controls the amount of sterilizing water supplied, the amount of liquid phase catalytic material supplied, the amount of gaseous catalytic material supplied, and the amount of power provided to the electrode module optimization device based on data detected in real time from the concentration sensor, thereby allowing the concentration of the generated hypochlorous acid water to be easily and stably controlled within a preset range.

[0057] The electrochemical reaction system according to the present embodiment can modify various fluid materials to desired properties through a specific mechanism.

[0058] Specifically, the mechanism of action of the electrochemical reaction system according to the present embodiment includes a condition in which electrolysis or plasma is applied while the sterilizing water to be reformed is pressurized at a predetermined pressure. At this time, a gas is generated during the process of electrolysis or plasma application, creating a generation environment. The next condition is a condition in which a specific gas is injected while the sterilizing water to be reformed is pressurized at a predetermined pressure, and then electrolysis or plasma is applied. The specific gas mentioned above is a gas for creating a plasma generation environment, and examples thereof include hydrogen, oxygen, ozone, nitrogen, carbon dioxide, argon, organic gas, methane, etc.

[0059] In this case, when the above-mentioned sterilizing water is pressurized at a predetermined pressure, the sterilizing water may be an organic substance, or in some cases, may be a fluid in which an organic substance and an inorganic substance are mixed. In addition, the above-mentioned sterilizing water may be heated to smoothly maintain fluidity depending on the viscosity, and the organic substance or the fluid in which an organic substance and an inorganic substance are mixed may be heated depending on the reaction environment.

[0060] The internal structure of the insecticide liquid container 200 is shown in Fig. 4. Compressed air supplied to the bottom of the insecticide liquid container 200 through a pipe line reaches the vibration generator 200 located at the bottom of the insecticide liquid container 200. The insecticide liquid container 200 is filled with the insecticide liquid solution injected through the insecticide liquid injection port 90, and the current water level is measured by the water level sensor 82. When the insecticide liquid solution is vaporized in the vibration generator 200, it passes through the insecticide liquid solution and is delivered to the outside of the insecticide liquid container 200 through the outlet 92 located at the top center of the insecticide liquid container 200.

[0061] Meanwhile, a control panel is provided for controlling the operation of the vibration generator 200 for vaporizing the insecticide solution. The control panel is provided with a connection port for wireless or wired connection to the outside. The control panel may be provided with a notification device for measuring the level of the insecticide solution present inside the insecticide solution container 200 with a water level sensor and for notifying the user of a shortage or excess of the insecticide solution. The control panel may also be provided with a setting section for setting the operation hold time or operation start time. The water level sensor 82 is installed inside the insecticide solution container to measure the amount of the insecticide solution. The water level sensor displays an upper limit and a lower limit.

[0062] A Venturi tube (not shown) may be provided in the compressed air supply pipe through which the compressed air is connected to the insecticide liquid container 200. The Venturi tube increases the flow rate and generates negative pressure, so that a separate chemical or solution can be introduced into the compressed air supply pipe through the Venturi tube.

[0063] That is, the Venturi tube may be connected to a separately provided tank, and one or more of the fumigant, N2, CO3, and He may be additionally supplied to the Venturi tube from the tank together with the carrier gas.

[0064] 4 and 5, vibration generator 200 has supply pipe 210 connected to a compressed air supply pipe, horn body 220 connected to an end of supply pipe 210, and outer part 230 in which horn body 220 is built, and outer hole forming surface with outer hole 230A formed therein is formed on the surface of outer part 230, and blade vibration plate 240 is attached to the outer hole forming surface. That is, blade vibration plate 240 is not attached to the surface where no outer hole is formed.

[0065] 5 includes an inner pipe 221 communicating with a supply pipe 210, and a volume portion 222 having a horn body groove 223 formed therein, which is a predetermined radial space, at a portion of the inner pipe 221 such that the inner pipe 221 is positioned along the central axis. A horn body hole 224 is formed penetrating the volume portion 222 from the horn body groove 223 such that the inside of the outer portion 230 and the inner pipe 221 communicate with each other.

[0066] In FIG. 6a, horn body holes 224 are formed in the volume portion in a radial direction from horn body groove 223 formed at a predetermined position of the inner tube into which compressed air flows, and horn body holes 224 are connected to a circulation chamber 260 formed in the internal space of outer portion 230.

[0067] Alternatively, the horn body groove may be formed in a conical shape as shown in FIG. 5c.

[0068] The horn body groove in Figure 5b is disk-shaped, with a curved surface formed along the circumference in the radial direction and of a constant height, as defined as disk-shaped horn body groove 223A, while the horn body groove in Figure 5c is defined as conical horn body groove 223B, with a conical cross section and a curved surface formed along the circumference in the radial direction from the apex to the end of the generatrix.

[0069] The horn body holes formed in the disk-shaped horn body groove 223A and the conical horn body groove 223B, respectively, may be formed radially perpendicular to the volume 222 as shown in FIG. 5a, or may be formed tangentially to the volume 222 for flow circulation in the circulation chamber.

[0070] In addition, the horn body holes are related to the shape of the outer part 230 of the horn body 220. That is, when the outer part 230 without the outer hole 230A is located at a position facing the horn body hole, only vaporized droplets of insecticide liquid that are small enough not to collide with the inner surface of the outer part among the insecticide liquid vaporized from the horn body hole can be discharged through the outer hole 230A. For this reason, it is preferable that the outer hole and the horn body hole are not overlapped with each other in the radial direction but are spaced apart from each other in the circumferential direction.

[0071] 5a shows the exterior where the horn body groove 223 is formed, FIG. 5b shows left and right spaces formed inside the horn body 220, and FIG. 5c shows top and bottom spaces formed inside the horn body 220. FIG.

[0072] The compressed air forms a flow path in the horn body groove 223 along the inner tube 221, but forms left and right spaces in the horn body as shown in Fig. 5b to prevent a sudden impact from being generated on the horn body 220. Also, a part of the compressed air flows from the inner tube 221 through the section where the horn body groove is formed to the bottom of the volume part 222, generating an impact on the horn body 220, especially the bottom of the horn body.

[0073] 4, one side of the vibration generator 200 and the horn body 220 is fixed to the compressed air supply line located at the top of the sterilizing water container 200, and the other side must be kept a certain distance from the bottom of the sterilizing water container 200, forming a so-called free end, which may be more vulnerable to vibration and shock. Therefore, in order to reduce vibration and shock caused by the compressed air, a horn body buffer part 222B is formed, which has a shape that becomes narrower from the horn body groove 223 downward.

[0074] On the other hand, when the outer part 230 having the outer hole 230A formed therein is positioned opposite the horn body hole, the vaporized droplets of the insecticide liquid that have vaporized from the horn body hole and passed through the outer hole 230A can be discharged through the outer hole 230A.

[0075] 5a and 6a, a circulation chamber 260 is formed between the outer portion 230 and the volume portion 222. The compressed air circulates along the circulation chamber 260.

[0076] In order to allow the compressed air moved to the inside of the outer portion 230 through the supply pipe 210 to rotate along the surface of the volume portion 222, the volume portion is formed to be inclined downward, the cross section of the horn body 220 becomes smaller toward the bottom, and the space between the horn body and the outer portion may have a narrow upper and wide lower structure.

[0077] That is, the volume of the horn body is formed to be inclined so that the cross section becomes smaller toward the bottom, and the space of the circulation chamber 260 between the volume of the horn body and the outer part may be a narrow upper and wide lower structure or space that becomes larger toward the bottom.

[0078] 5 and 6, two or more external holes 230A are formed in the external portion 230 so that the compressed air moves toward the blade diaphragm 240. The external holes 230A may have a diameter of 0.3 to 0.8 mm and may be arranged irregularly or regularly on the surface of the external portion 230. The external holes are formed in the external portion that forms a circulation chamber space between the volume portion and the external hole.

[0079] The outer part 230 is formed in a polygonal column shape. The outer hole 230A is opened toward one surface of the wing diaphragm 240 facing one side of the outer part 230. The wing diaphragm 240 is formed in a plate shape. One side of the wing diaphragm 240 is fixed to one side of the outer part 230, and the other side of the wing diaphragm 240 forms a plate with a length extended from one side of the outer part.

[0080] As shown in Fig. 6b, in order to extend the length of the blade diaphragm, the cross section of the outer part 230 of the vibration generator is formed in a polygonal shape. That is, in the embodiment of Fig. 6b, the outer part has a hexagonal cross section (N=6), and one or more outer holes 230A may be formed on N (N is a natural number of 3 or more) faces forming the side of the outer part. That is, the outer hole 230A may be formed to penetrate the outer part, forming a circulation chamber 260 space between the volume part 222 and the outer part.

[0081] N vibration plates 240 are fixed to one side of the N faces where the outer holes 230A are formed and cover the N faces, and the compressed air in the circulation chamber can pass through the outer holes and hit the N vibration plates. One side of the vibration plate 240 is fixed to one side of the outer part 230, and the other side of the vibration plate 240 can form a plate body with a length extended from one side of the outer part.

[0082] That is, the surface of the outer part is surrounded by several rectangular outer surfaces each having a predetermined area, and the wing diaphragm is rectangular, and one side of the wing diaphragm is fixed so as to overlap one side of the outer surface, and the other side of the wing diaphragm is not fixed and extends from the outer surface to be exposed to the outside of the vibration generating part. Although one side of the wing diaphragm is fixed to one side of the outer surface, there is no force restraining the other side of the wing diaphragm, and when a certain force or pressure is applied to the wing diaphragm, the further away from the fixed one side of the wing diaphragm, the more it bends and restores a predetermined displacement due to the elasticity of the wing diaphragm, generating vibration.

[0083] That is, the compressed air reaching the wing vibration plate 240 through the outer hole 230A collides with the wing vibration plate 240. The wing vibration plate 240 generates ultrasonic waves and shock waves by the hydrodynamic sound source, and countless bubbles are generated in the insecticide liquid present in the insecticide liquid container.

[0084] In addition, the cross section of the outer shape may be a circle instead of an N-sided polygon. If the outer shape is a circle, the diaphragm may be formed along the circumference. In this case, the bottom surface may be a sector instead of a triangle.

[0085] The vibration generator 200 further includes a piezoelectric element 250 that vibrates the horn body 220, the outer part 230, and two or more wing vibration plates 240. The piezoelectric element 250 is located between the horn body 220 and the supply pipe 210. The operation of the piezoelectric element 250 accelerates the vibration of the wing vibration plate 240. An impact is applied to the bubbles generated in the wing vibration plate 240, and fine vaporized gas is generated in the insecticide liquid.

[0086] Just as wing diaphragm 240 is formed on the side of vibration generator 200 in Fig. 7, bottom diaphragm 242 may be formed on the underside. The cross section of bottom diaphragm 242 is the same as the cross section of the outer part, which is a polygon with N sides (triangle in Fig. 7) and has the same shape as the outer part of the vibration generator. If the cross section of the outer part of the vibration generator is a circle rather than a polygon, the bottom diaphragm will be fan-shaped.

[0087] In this embodiment, each of the bottom vibration plates has a triangular shape as shown in Fig. 6b and Fig. 7a, and the common vertex of the N triangles can be fastened by the bottom fastening part 244. The bottom fastening part 244 serves as a lower plug of the inner tube 221 and fixes the bottom vibration plate. That is, it is separated by the number of outer surfaces of the vibration generator, and is fixed by the bottom fastening part 244 at the center of the lower surface of the vibration generator. A bottom hole 246 is formed on the lower surface of the side of the vibration generator 200 facing the bottom vibration plate of the bottom fastening part, like the outer hole 230A, and atomized insecticide liquid is generated by collision between the outer hole 230A and the bottom vibration plate 242 that is not attached and fixed to the bottom hole 246 but is separated by a small distance like the wing vibration plate 242.

[0088] Meanwhile, the triangular bottom diaphragm 242 may be formed to extend in the radial direction so as to be larger than the area of ​​the bottom surface of the vibration generator.

[0089] The triangular bottom diaphragm 242 can be formed at a position extending further downward from the lower surface of the vibration generator, that is, in the longitudinal direction of the vibration generator, to avoid interference with the wing diaphragm 242 .

[0090] Also, as shown in FIG. 7b, when the bottom fastening portion 244 is disassembled, the inside of the vibration generator can be purged of contamination or residues by compressed air through the bottom hole 246.

[0091] In Fig. 8, the sterilizing bubble water and vaporized insecticide liquid generated from the sterilizing bubble water and insecticide liquid sprayers are discharged through the outlets located at the top of the sterilizing and insecticide sprayers, respectively. The sterilizing bubble water flows in through a flow path formed at the top along the rear end of the sterilizing and insecticide sprayers, and is sprayed through the sterilizing bubble water outlet 280 together with compressed air in the form of a two-fluid nozzle for sterilizing bubble water by compressed air supplied from a three-way valve, and a fan 290 is installed above the outlet of the sterilizing bubble water to adjust the diffusion within the space during spraying.

[0092] FIG. 9 shows a structure for enhancing the circulation flow of the circulation chamber 260. FIG. 9a shows the position of the horn body hole 224 from the disk-shaped horn body groove 223A formed at a predetermined position of the inner tube 221 to the circulation chamber 260, and the horn body hole is formed from the most protruding part of the cross section of the disk-shaped horn body groove. FIG. 9b shows the case of a cone-shaped horn body groove 223B, and the horn body hole is formed from the most protruding part of the cross section. FIG. 9cd shows a structure in which the horn body hole 224 is formed downward, preventing the horn body groove from being filled with fluid during operation and not being able to be discharged any more. In this case, the opening position of the horn body hole may be located lower than FIG. 9ab. FIG. 9e shows a case in which the horn body hole is viewed from above, and is located in a radial direction at a predetermined angle apart and perpendicular to the volume. FIG. 9f shows a structure in which the horn body hole is formed in a curved swirl type, which can better induce a swirl flow in the circulation chamber. Figure 9ef shows a possible taper type in which the cross section narrows the further away from the horn body groove. In other words, there may be a partial region in which the cross section narrows as one moves radially from the horn body groove.

[0093] The vaporized insecticide liquid is positioned in front of the two-fluid nozzle for sterilizing bubble water and lower than the position of the two-fluid nozzle for sterilizing bubble water, so that the insecticide liquid is sprayed through the insecticide liquid outlet 270 to target a position closer to the sterilization and insecticide sprayer.

[0094] The disinfecting and insecticidal sprayer can be loaded into a portable smart device in the form of a program for operating the sprayer on-site.
