Description

[Technical field]

[0001] This embodiment relates to an agricultural fogger that amplifies the amount of vortex generated and increases heat exchange efficiency through a structure in which a steel wire of a certain diameter is inserted into a pipe. [Background technology]

[0002] Agricultural fog machines are equipped with a heat exchange device that heats the chemical solution using a heater or the like and sprays it to the outside. The insecticide is passed through a high-temperature heater, which either vaporizes the fluid or maintains it at a high temperature in a form that makes it easy to spray the chemical.

[0003] The pipe inside the heater used in the conventional agricultural fogger is a coiled pipe to increase the heat exchange area and length. The coiled pipe has problems such as the viscosity of the pesticide or other chemicals increasing as it is heated, or the impurities on the inner wall blocking the flow path, causing frequent clogging.

[0004] The clogging of the pipes inside the heater of the agricultural fog machine causes the need to replace the entire heater, which increases the manufacturing and management costs of the agricultural fog machine and increases the cost of production.Furthermore, frequent removal and installation of the heater of the agricultural fog machine, which includes electronic devices, is pointed out as a factor that shortens the life of the agricultural fog machine. Summary of the Invention [Problem to be solved by the invention]

[0005] In this context, the object of the present embodiment is to provide an agricultural fogger that, in one aspect, does not employ a coiled pipe but uses a straight tube, thereby reducing clogging and making it easier to clean if clogging does occur.

[0006] The purpose of this embodiment is to provide an agricultural fogger that can improve heat exchange efficiency by inserting a steel wire of a certain diameter into the pipe, thereby generating a vortex flow, in order to solve the problem that normal spraying is difficult due to the small heat exchange area, unlike in other aspects of coil-shaped pipes.

[0007] An object of the present embodiment is to provide an agricultural fogger in yet another aspect, which employs multiple pipes in a multi-stage configuration and forms patterns (e.g., helical diagonal lines, mesh netting, etc.) on the inner and outer surfaces of the pipes to enhance the generation of a vortex effect.

[0008] The object of the present embodiment, in yet another aspect, is to provide a fog machine that minimizes the use of chemicals to reduce the residence time of fluid passing through the pipes, and is light in weight and easy to carry. [Means for solving the problem]

[0009] In order to achieve the above object, a first embodiment can provide an agricultural fog machine comprising: a chemical solution storage tank installed inside the fog machine and supplying the chemical solution; a transfer pump that delivers the chemical solution stored in the chemical solution storage tank through a conduit and adjusts the flow rate of the chemical solution; a heater housing that adjusts the temperature of the chemical solution transferred from the transfer pump through one or more heat exchangers installed inside and controls the temperature of the chemical solution transferred to the outside of the fog machine through an injection tube; and a steel wire that is inserted into the path of movement of the chemical solution in the heater housing and generates a vortex.

[0010] In the agricultural fogger, the heater housing may include a straight conduit through which the chemical solution passes, and the steel wire may be inserted into the straight conduit.

[0011] In the agricultural fog machine, the steel wire is inserted in the opposite direction to the moving path of the chemical solution, and one end of the steel wire can be fixed, and the other end of the steel wire can be left unfixed.

[0012] In the agricultural fogger, a passage for the chemical solution is formed in an internal conduit of the heater housing, and the steel wire may be inserted into the internal conduit. The surface of the steel wire and the inner wall of the internal conduit may be patterned in a spiral shape having opposite directions.

[0013] In the agricultural fogger, the heater housing includes an inner pipe and an outer pipe, and the inner pipe and the outer pipe can separate the flow path of the chemical solution.

[0014] In an agricultural fogger, the steel wire may include a plurality of grooves formed along a spiral pattern.

[0015] The agricultural fogger may further include a support structure for supporting the steel wire, and the support structure may further include an inner ring surrounding the steel wire and an outer ring attached to the surface of the spray pipe.

[0016] In order to achieve the above-mentioned object, a first embodiment provides an agricultural fogger that heats and sprays a chemical solution, the agricultural fogger comprising: a transfer pump that adjusts and transmits a flow rate of the chemical solution; an internal conduit through which the chemical solution delivered from the transfer pump passes; a heater housing that adjusts the temperature of the chemical solution passing through the internal conduit and transmits it to the outside; and an insertion structure that is inserted inside the internal conduit and generates a vortex in the flow of the chemical solution.

[0017] In the agricultural fogger, the internal conduit may be a straight pipe, and the insertion structure may be slidably inserted in a direction opposite to a chemical solution movement path of the internal conduit, and one end of the insertion structure may be fixed.

[0018] In an agricultural fogger, a surface of the internal conduit or the insert structure may be patterned to create friction with the chemical solution. Effect of the Invention

[0019] As described above, according to this embodiment, a straight pipe structure is adopted, and the problem of the contact time with the inner wall of the heater tube decreasing due to an increase in the fluid movement speed during spraying of the chemical solution can be solved by inserting a steel wire.

[0020] According to this embodiment, the spray efficiency of the chemical solution can be improved based on the generation of vortexes by the steel wire and the increased residence time, and since a large-capacity heater is not used, the agricultural fog machine can be made smaller.

[0021] According to this embodiment, a steel wire is inserted inside the heater pipe, and heat exchange occurs on the inner wall of the heater pipe due to the load and vibration applied during the transfer of the chemical solution, and at the same time, heat exchange also occurs in the steel wire. In the process of the transfer of the chemical solution, a vortex phenomenon occurs through the steel wire, and the contact area between the chemical solution and the inner wall of the heater pipe is significantly increased, allowing the chemical solution to be sprayed very efficiently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, some embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that when adding reference numerals to components in each drawing, the same numerals are used to the same components as long as possible even if they are shown in other drawings. In addition, in describing the present invention, detailed descriptions of related known configurations or functions that are considered to make the gist of the present invention unclear will be omitted.

[0024] In addition, when describing components of the present invention, terms such as first, second, a, b, etc. are used. Such terms are used to distinguish the components from other components, and do not limit the nature, order, sequence, etc. of the components. When a component is described as being "coupled," "coupled," or "connected" to another component, it should be understood that the component can be directly coupled or connected to the other component, but another component may be "coupled," "coupled," or "connected" between each component.

[0025] FIG. 1 is a diagram explaining the operation process of an agricultural fogger operated in conjunction with a smartphone.

[0026] Referring to FIG. 1, the fog machine 30 can be operated in cooperation with a smartphone 10, a server 20, and the like.

[0027] Data generated by touch input to the smartphone 10 can be transmitted to the server 20, and the server 20 can transmit a control signal to the fog machine 30 for controlling the operation of the fog machine 30.

[0028] The smartphone 10 is a device capable of running an application or a computer program, and may be any mobile device. For the sake of convenience, the smartphone 10 will be referred to as a smartphone in the following description, but the embodiments of the present specification are not limited thereto.

[0029] The screen of the mobile application run on the smartphone 10 can provide a user interface (UI) for controlling the power of the fog machine 30, controlling the components inside the heater housing, controlling the output of the transfer pump, or controlling the illumination of the Light Emitting Diodes (LEDs).

[0030] The server 20 may refer to an internal storage device installed in a computer device, but is not limited to this, and may include a cloud server, etc.

[0031] The server 20 can receive and store control signals generated by touch input to the smartphone 10, and can transmit the results of appropriate calculations through an internal algorithm to a control board stored inside the aerosol machine 30.

[0032] The fogger 30 is a device for spraying pesticides or other liquid medicines for insect control, and may include a liquid medicine storage tank (not shown), a transfer pump (not shown), a heater housing (not shown), a control board (not shown), a relay (not shown), etc.

[0033] The fog machine 30 receives a wireless communication signal (eg, a Wi-Fi signal) transmitted through the smartphone 10 and the server 20, and can be remotely controlled without the user directly controlling the operation of the fog machine 30.

[0034] The operation of the fog machine 30 can be divided into a step of applying power, a step of running an application, a step of remotely controlling the fog machine, and the like.

[0035] The step of remotely controlling the fog machine includes the steps of operating the heater chamber to maintain the temperature of the fog machine at a reference temperature, operating the transfer pump, injecting the chemical solution, operating the heater housing to perform heat exchange, and restarting the transfer pump, and these repeated operations can be controlled differently depending on the required set number of times.

[0036] For example, if a user inputs a one-touch signal, the heater can be operated for 330 seconds, followed by the pump for 20 seconds, and then the heater can be operated for 80 seconds, followed by the pump for 20 seconds, and such operations can be repeated and controlled by the mobile application.

[0037] Illustratively, if a user inputs a drain signal, the drain pump can be activated.

[0038] For example, when a user inputs a lighting signal, the timer function can be operated in a toggled manner.

[0039] Illustratively, when a forced termination signal is input, a control board (eg, a microprocessor (MCU) board) may be reset.

[0040] FIG. 2 is a block diagram for explaining the internal configuration of the agricultural fogger according to one embodiment.

[0041] Referring to FIG. 2, the agricultural fogger 200 may include a chemical solution storage tank 110, transfer pumps 120-1, 120-2, heat exchangers 130-1, 130-2, a buzzer 140, a temperature measuring device 150, a temperature fuse 160, a control board 170, a relay 180, a circuit breaker 190, etc.

[0042] The agricultural fogger 200 may include a heater housing 145, which may be defined as including heat exchangers 130-1 and 130-2, a buzzer 140, a temperature measuring device 150, a temperature fuse 160, a relay 180, etc. In the following, for convenience of explanation, the term "heater housing" is used, but the present embodiment is not limited to such a term, and other terms such as "heater device" may be used.

[0043] The liquid medicine storage tank 110 may be a space installed inside the fog machine for storing liquid medicine such as insecticide, and the size and shape of the liquid medicine storage tank may be defined in various ways depending on the operation time and weight of the fog machine. For example, the liquid medicine storage tank 110 may be a cylindrical or rectangular storage tank.

[0044] The transfer pumps 120-1 and 120-2 transfer the chemical liquid stored in the chemical storage tank through flexible conduits 111 and 121, and can adjust the flow rate of the chemical liquid transferred to the heater housing 145 through the conduits 111 and 121 in response to a control signal transmitted from the control board 170.

[0045] When flexible conduits 111, 121 are used, it is possible to save space inside the fog machine 200. For example, when the chemical storage tank 110 and the transfer pumps 120-1, 120-2 are adjacent to each other, or when the chemical storage tank 110, the transfer pumps 120-1, 120-2, and the heat exchangers 130-1, 130-2 are not positioned on a straight line, it is possible to improve space efficiency.

[0046] The pipes inside the fog machine, including the conduits 111 and 121, can be made of a metal such as copper, but are not limited thereto.

[0047] The configuration of the transfer pumps 120-1 and 120-2 may include, but is not limited to, a drive motor (not shown) for providing a driving force such as a rotary driving force, a cylindrical pump piston (not shown) for adjusting the flow rate, etc.

[0048] The number of the transfer pumps 120-1 and 120-2 may be defined differently depending on the number of the heat exchange devices and the injection pipes. For example, when the number of the injection pipes 131 is two, two transfer pumps may be formed.

[0049] For more efficient pump operation, a physical or electrical connection may be formed between the transfer pumps 120-1, 120-2.

[0050] The transfer pumps 120-1, 120-2 can control the flow rate of the chemical liquid transferred to the conduit 121 or the injection pipe 131, and the flow rate of the chemical liquid can be changed depending on the heat exchange efficiency of the heat exchangers 130-1, 130-2 or a control signal from the control device 170.

[0051] The transfer pumps 120-1, 120-2 can transfer unheated fluid to the heat exchangers 130-1, 130-2.

[0052] The heat exchangers 130-1 and 130-2 are connected to the conduit 121 and can increase the temperature of the chemical solution, and can have a shape surrounding the conduit 121 for perpendicular or counter flow.

[0053] The heat exchangers 130-1 and 130-2 may further include an internal conduit (not shown) passing through the conduit 121 and the injection pipe 131, and may adjust the temperature of the chemical solution passing through the internal conduit (not shown).

[0054] The injection pipe 131 can inject the fluid transmitted through the heat exchangers 130-1 and 130-2 through a spray nozzle (not shown) or the like, and can be equipped with a filter (not shown) or the like, if necessary, to prevent the nozzle holes from becoming clogged.

[0055] Since fine particles can be sprayed through the spray tube 131, the adhesion of the drug can be improved, and the amount sprayed can be controlled as needed, optimizing the use of the drug.

[0056] The buzzer 140 may be a device that generates an alarm for safety reasons or to prevent an external collision of the unmanned fog machine 200. For example, the buzzer 140 may generate an alarm continuously during the operation of the fog machine 200.

[0057] The temperature measuring device 150 may be a device for measuring the temperature inside the heater housing 145 or for measuring the temperatures of the heat exchangers 130-1 and 130-2.

[0058] The temperature measured by the temperature measuring device 150 can be transmitted to the control board 170, and the control board 170 can generate a control signal, such as cutting off the current of the thermal fuse 160, based on the corresponding temperature signal.

[0059] The thermal fuse 160 may refer to a metal wire that melts and cuts off the flow of current before the electrical components do, similar to a typical fuse, when a strong current flows, and may either react directly to the temperature inside the heater housing 145 or cut off the current in response to a control signal from the control board 170.

[0060] The heater housing 145 may further include a temperature switch (not shown), which may be connected to the control board 170 or the relay 180 to perform a switching function therein.

[0061] The control board 170 may be a microcontroller (MCU) or a processor for controlling the operation of the internal components of the fog machine 200 or for performing calculations for such operation. If necessary, a memory (not shown) for storing data may be further provided.

[0062] The control board 170 can control the operation of the heater housing 145 and can preheat the heater housing 145. When the fog machine 200 is initially heated, the preheating process can be performed to improve the operating efficiency of the fog machine 200.

[0063] The control board 170 can control the operation of the transfer pumps 120-1 and 120-2, and can operate the transfer pumps 120-1 and 120-2 to adjust the flow rate of the chemical liquid.

[0064] The control board 170 can control the operation of the heat exchangers 130-1, 130-2, and can operate the heat exchangers 130-1, 130-2 to adjust the temperature of the chemical liquid.

[0065] The control board 170 can generate control signals to check and adjust the temperature or humidity inside the fog machine 100, can generate control signals regarding whether a fan (not shown) is operating and its operating output, can generate control signals regarding whether a heater is operating and its operating output, and can generate control signals to adjust the illuminance of the LED lighting.

[0066] The relay 180 is electrically connected to the control board and can change the output signal according to the current transmitted to the electromagnet installed inside. When the direction of the relay 180 is reversed so that the magnet part is located at the top, it can exhibit higher stability.

[0067] The circuit breaker 190 is configured to be able to interrupt an analog signal (for example, a voltage or a current) transmitted from the outside as necessary.

[0068] FIG. 3 is a diagram for explaining the configuration of a heater housing inside the agricultural fogger according to one embodiment.

[0069] Referring to FIG. 3, the heat exchanger 130 may include a fluid transmission section 132, a heat exchange section 133, and the like.

[0070] The heat exchanger 130 may transfer heat to a fluid that a transfer pump (not shown) delivers via conduit 121 and expels the hot fluid via an ejection tube 131 .

[0071] The fluid transmission part 132 can transmit the heated fluid to the heat exchange part 133 for heat exchange, and the configuration of the fluid transmission part 132 can be designed in various ways.

[0072] The heat exchange section 133 is adjacent to the conduit 121 and the injection pipe 131 and can increase the temperature of the fluid sprayed through the injection pipe 131 by transferring high-temperature fluid, and the amount of change in temperature can be changed in real time by receiving temperature data set in the control board 170.

[0073] Coiled pipes can be used for the heat exchanger 133, the conduit 121, and the injection pipe 131, but straight pipes can also be used. For reasons described below, when straight pipes are used, a steel wire (not shown) can be inserted to increase the amount of vortex generation, improving the heat exchange time and heat exchange efficiency of the chemical solution, thereby reducing the size of the heater housing.

[0074] When the heat exchanger 130 forms a liquid medicine passage with a straight pipe structure, the transfer speed during liquid medicine injection is high. As a result, the contact time between the heat exchanger 133 and the liquid medicine is short and the area is small, which reduces the efficiency of injection. In general, the heat exchanger 130 structure solves this problem by using a large-capacity heater housing or by increasing the liquid medicine passage.

[0075] When a steel wire (not shown) is inserted inside the heater pipe of the heat exchanger 130, heat exchange can be performed not only on the inner wall of the heater tube but also on the steel wire due to a change in the movement path of the fluid on the steel wire during the transfer of the chemical solution (for example, collision between the fluid and the steel wire). When a steel wire (not shown) is inserted into the internal conduit of the heat exchanger 130, a vortex phenomenon occurs in the flow of the chemical solution through the steel wire during the process of the chemical solution being transferred, increasing the contact time between the chemical solution and the inner wall of the heater tube, allowing the chemical solution to be sprayed very efficiently. This allows very efficient spraying even with a heater housing with a small capacity, and the size of the heater housing can be reduced, making the agricultural fog machine more compact.

[0076] While the electricity available in most conventional greenhouses is 3kW or less, a large heater of 6kW or more is required for spraying with a straight tube sprayer, making it difficult to use in rural facilities. In contrast, if a steel wire is inserted inside the straight tube of a heater room of the same size, spray efficiency can be greatly improved even with a small heater of 2.5kW or less, making it possible for farmers to operate a fog machine without adding additional equipment.

[0077] The heat exchanger in FIG. 3 is shown merely to illustrate a heat exchange method for adjusting the temperature of the chemical solution, and the technical idea of ​​the present embodiment is not limited thereto.

[0078] FIG. 4 is a diagram for explaining the operation control of the control board of the agricultural fogger according to one embodiment.

[0079] Referring to FIG. 4, the control board 370 may include a power control unit 371, a heater control unit 373, a pump control unit 375, a lighting control unit 377, and the like.

[0080] The power supply control unit 371 generates a signal to control the power supply 381 inside the fog machine 380, and can adjust the output intensity of the power supply 381 or change the power supply to an on or off state.

[0081] The heater control unit 373 generates a signal to control the heater 383 inside the fog machine 380, and adjusts the temperature inside the heater 383 or adjusts the inflow of high-temperature fluid delivered to the inside of the heater, thereby changing the temperature condition inside the heater 383. The heater 383 may refer to a heater housing (not shown), or may refer to the internal configuration of the heater housing.

[0082] The pump control unit 375 generates a signal to control a transfer pump 385 inside the fog machine 380, which can control the transfer pump 385 and control the flow rate or flow pressure of the fluid transmitted through a conduit (not shown).

[0083] The lighting control unit 377 generates a signal to control the LED lighting 387 inside the fog machine 380, and controls the LED lighting 387 to change the amount of light emitted or the output intensity of each element.

[0084] The control board 370 may include a power supply control unit 371, a heater control unit 373, a pump control unit 375, and a lighting control unit 377, which may represent individual circuit configurations implemented within a single control board 370, or may be configured as separate circuits.

[0089] Referring to Figures 5 to 8, the agricultural fogger 400 may include a chemical solution storage tank 410, a chemical solution tap 411, a first transfer pump 420-1, a second transfer pump 420-2, a first heat exchanger 430-1, a second heat exchanger 430-1, a spray pipe 431, a control board 470, a handle 496, a frame 497, an exhaust fan 498, an intake fan 499, etc.

[0090] The agricultural fogger 400 according to an embodiment of the present invention has a more stable structure and can generate high spray efficiency through the arrangement as shown in FIGS.

[0091] A liquid medicine storage tank 410 may be fixed to the upper part of the frame so that the liquid medicine can be injected into the frame, and a liquid medicine plug 411 can prevent the liquid medicine from being exposed to the outside air.

[0092] The liquid medicine plug 411 can be opened only when the liquid medicine is to be injected.

[0093] The first transfer pump 420-1 and the second transfer pump 420-2 may be installed separately at the lower stage of the chemical solution storage tank 410, or may be fixed to the lower stage of the frame.

[0094] The first transfer pump 420-1 and the second transfer pump 420-2 may be installed around the chemical solution storage tank 410.

[0095] The first transfer pump 420-1 and the second transfer pump 420-2 may be the transfer pumps described above and may be arranged to increase spatial efficiency since the drug solution can be delivered by flexible pipes.

[0096] The first transfer pump 420-1 and the second transfer pump 420-2 may be installed at a certain distance from the bottom to improve durability, and may be fixed to one side of the frame.

[0097] The first heat exchanger 430-1 and the second heat exchanger 430-1 are installed on the opposite side to the side where the transfer pump is installed, and form an outlet so that the injection pipe 431 can protrude to the outside of the atomizer.

[0098] The first heat exchanger 430-1 and the second heat exchanger 430-1 can be individually connected to each of the multiple injection pipes 431.

[0099] The injection pipe 431 may be installed on one side of the frame 497, or may be formed by cutting and then welding.

[0100] The injection pipe 431 may be connected to the outside of the fog machine through a hole formed in the frame 497 .

[0101] The control board 470 can perform the functions of the control board described above, and is installed in the center of the fog machine 400 to improve durability, thereby preventing a decrease in durability due to vibration.

[0102] The control board 470 may be mounted to one side of the frame 497 .

[0103] A handle 496 is located on the top portion of the fogger 400 and can be used to move the fogger 400 .

[0104] The frame 497 can separate the external environment and the internal components of the fog machine 400, and can generate a physical or thermal isolation effect. The shape of the frame 497 can be, but is not limited to, a rectangular parallelepiped shape.

[0105] The exhaust fan 498 can be configured to exhaust air from within the fog machine 400 .

[0106] The intake fan 499 can be configured to draw in air from outside the fog machine 400 .

[0107] 5 to 8 are intended to illustrate the structure of the agricultural fogger according to this embodiment, and the technical idea of ​​this embodiment is not limited thereto.

[0108] FIG. 9 is a diagram illustrating an agricultural fogger using a coil pipe-shaped conduit.

[0109] Referring to FIG. 9, an agricultural fogger 500 may include an internal conduit 510, a heat exchanger 520, an atomizing tube 530, and the like.

[0110] The internal conduit 510 can receive thermal energy from the heat exchanger 520 to adjust the temperature of a fluid (eg, a medicinal liquid) and transmit it to the spray tube 530 .

[0111] The conventional internal conduit 510 uses a coil pipe type conduit, which causes frequent clogging, which causes the problem of having to replace the entire heater housing, which is a practical limitation that increases costs and makes after-sales (A / S) more difficult.

[0112] The coil pipe 510 increases the fluid residence time to improve heat exchange efficiency and increases the effective heat exchange time, but when the passing fluid is a mixture, there is a problem that clogging occurs due to internal sedimentation or precipitation.

[0113] If a straight pipe-shaped conduit is used to improve the clogging of the inner conduit 510, the clogging can be reduced, but the heat exchange area and time are reduced, so that heat exchange cannot be performed to the required temperature. In particular, in the straight pipe structure, the moving speed of the sprayed chemical increases, and in order to improve the heat exchange efficiency, the length of the conduit must be increased by using a large-capacity heater housing. This increases the size of the agricultural fog machine, and the portability of the agricultural fog machine is rapidly reduced.

[0114] FIG. 10 is a diagram showing the internal configuration of an agricultural fogger of a straight pipe structure with a steel wire inserted therein according to one embodiment.

[0115] FIG. 11 is a cross-sectional view of the inside of an agricultural fogger of a straight pipe structure with a steel wire inserted therein according to one embodiment.

[0116] 10 and 11, an agricultural fogger 600 according to this embodiment may include an inner conduit 610, a steel wire 650, and the like.

[0117] The agricultural fogger 600 may further include a chemical solution storage tank (not shown) that is installed inside the fogger and supplies the chemical solution, a transfer pump (not shown) that transfers the chemical solution stored in the chemical solution storage tank through a flexible conduit and adjusts the flow rate of the chemical solution, and a heater housing (not shown) that adjusts the temperature of the chemical solution delivered from the transfer pump through one or more heat exchangers installed inside and controls the temperature of the chemical solution delivered to the outside of the fogger through the injection tube.

[0118] The internal conduit 610 may be formed inside the heater housing (not shown) and may be a conduit through which a chemical solution may pass.

[0119] The inner conduit 610 utilizes a straight pipe structure to reduce clogging and facilitate cleaning when clogging occurs. By inserting a steel wire 650 into the fluid movement path of the inner conduit 610 (e.g., the center of the conduit) to increase the fluid residence time and increase the heat exchange time, these drawbacks can be compensated for.

[0120] The inner conduit 610 may include a number of protrusions 611 and grooves 612 to provide a patterned surface, although patterning of the inner conduit 611 may be omitted if desired.

[0121] The steel wire 650 may be a structure that can be inserted into the heater housing (not shown) to generate a vortex flow and change the path of fluid movement, and inserted into the inner conduit 610. The steel wire 650 may employ a material such as steel, but may employ any metallic substance.

[0122] The steel wire 650 may be inserted in the opposite direction to the path (direction) of movement of the chemical solution, and one end may be fixed. The steel wire 650 may be maintained in a state in which one end is fixed and the other end is not fixed. The not-fixed end of the steel wire 650 may generate vibrations due to the flow of fluid, amplify the generation of vortexes, generate a fluid mixing effect, and improve heat exchange efficiency. The not-fixed end of the steel wire 650 may play a role in exchanging the fluid that has undergone heat exchange on the surface of the internal conduit 610 with a fluid that has not undergone heat exchange.

[0123] The steel wire 650 is inserted in the opposite direction to the moving path of the drug solution, which allows the user to adjust the degree of insertion of the steel wire 650. One end of the steel wire 650 to be fixed may be fixed by a support structure 655 such as a screw, or may be connected and fixed by surface friction of the internal conduit 610. The steel wire 650 may be defined by an insertion structure, etc., as necessary.

[0124] The steel wire 650 may be a cylindrical structure having a certain diameter, but may be formed as a structure having a tapered shape such as a cone, and may be designed to generate flexible movement inside the internal conduit 610 and have a binding force at the end, and may have various modified embodiments, but is not limited to these. The length and thickness of the steel wire 650 may be a size that is pre-calculated and defined based on the target heat exchange efficiency of the internal chemical liquid, which may be defined by the resonant frequency of the fluid, but this embodiment may employ various measurement criteria, but is not limited to these.

[0125] The surface of the steel wire 650 and the inner wall of the heater housing (e.g., the inner wall of the inner conduit 610) may be patterned in a spiral having opposite directions. For example, the surface of the steel wire 650 may have a clockwise spiral pattern, and the inner wall of the inner conduit 610 may have a counterclockwise spiral pattern. The surface patterning of the steel wire 650 and the inner conduit 610 is for increasing the internal vortex effect and improving the heat exchange efficiency, and may be defined in various ways depending on the diameters of the steel wire and the conduit, and each surface patterning may be performed independently and selectively.

[0126] Surface patterning of the steel wire 650 and inner conduit 611 may be employed for eddy current amplification, but may be implemented in an abbreviated form if desired.

[0127] The flow of the chemical solution shown in Figures 10 and 11 is intended to illustrate the vortex flow generated by the spiral patterning of the steel wire, and the flow of the chemical solution inside the agricultural fogger is not limited to this.

[0128] FIG. 12 is a diagram for explaining an internal pattern of a pipe according to an embodiment.

[0129] Referring to FIG. 12, the internal conduit 610 may include a number of protrusions 611 and grooves 612 on the internal or external surface to form a pattern.

[0130] When the agricultural fogger uses one internal conduit 610, the protrusions 611 and grooves 612 can be realized in a screw-like twisted shape inside to form a helical pattern, but are not limited thereto.

[0131] When the agricultural fogger uses multiple internal conduits 610, the protrusions 611 and grooves 612 can be implemented in a screw-like twisted shape on the inside or outside to form a helical patterning, but are not limited thereto.

[0132] FIG. 13 is a diagram for explaining a surface pattern of a steel wire according to one embodiment.

[0133] Referring to FIG. 13, a steel wire 650 may have a number of protrusions 651 and grooves 652 on its surface to form a certain pattern.

[0134] A plurality of protrusions 651 and grooves 652 may be formed along a spiral pattern formed in the steel wire 650, and each protrusion 651 and groove 652 may have the same or different sizes and shapes. If desired, the steel wire 650 may be configured with various sizes and shapes of protrusions 651 and grooves 652 to form a random pattern, but is not limited thereto.

[0135] The steel wire 650 can improve the friction and heat exchange of the fluid by forming a primary pattern through N main lines (N is a natural number equal to or greater than 2) and forming a secondary pattern through the protrusions 651 and grooves 652. The protrusions 651 and grooves 652 have a hook shape in the opposite direction to the flow direction of the fluid, thereby increasing the friction force, increasing the residence time of the fluid, and improving the mixing rate.

[0136] The steel wire 650 may have a plurality of protrusions 651 and grooves 652 to enhance the generation of vortex currents, but may have a smooth surface without any separate patterning.

[0137] FIG. 14 is a diagram for explaining a multi-stage pipe structure according to one embodiment.

[0138] Referring to FIG. 14, an agricultural fogger 700 can include multiple pipes, including an outer pipe 710-1, an inner pipe 710-2, a steel wire 750, and the like.

[0139] The external pipe 710-1 and the internal pipe 710-2 can separate the movement path of the chemical solution, and thus it is possible to adjust the spray angle, spray speed, etc. of the first chemical solution movement path formed between the external pipe 710-1 and the internal pipe 710-2 and the second chemical solution movement path formed between the internal pipe 710-2 and the steel wire 750. By adjusting the cross-sectional area and diameter of the external pipe 710-1, the internal pipe 710-2, and the steel wire 750, it is possible to appropriately control the spray amount and distance of the chemical solution, and such calculations can be performed taking into consideration Bernoulli's theorem, etc.

[0140] The outer pipe 710-1, the inner pipe 710-2, and the steel wire 750 can be patterned on their surfaces to effectively create a vortex effect, and the lengths of the inner pipe 710-2 and the steel wire 750 can be adjusted to be different from each other to change the internal fluid movement path.

[0141] The internal pipe 710-2 can be patterned in a spiral shape, and if necessary, can have mesh-like or other holes to mix the fluid movement paths.

[0142] The steel wire 750 can generate vortexes in the moving path of the inner pipe 710-2 or generate vortexes in the moving path of the outer pipe 710-1.

[0143] By inserting a steel wire into multiple pipes such as the outer pipe 710-1, the inner pipe 710-2, and the steel wire 750, the vortex generation effect of the internal fluid can be maximized.

[0146] The agricultural fogger 800 may further include a transfer pump (not shown) that adjusts and transfers the flow rate of the chemical solution, a heater housing (not shown) that passes the chemical solution delivered from the transfer pump, adjusts the temperature of the chemical solution, and transfers it to the outside, etc.

[0147] The internal conduit 810 may be a conduit through which a liquid medicine is delivered from a transfer pump (not shown), and may be realized as a separate type or an integrated type with the injection pipe 830. The internal conduit 810 may be a straight pipe, and the surface of the internal conduit 810 may form a certain pattern, but is not limited thereto.

[0148] The injection pipe 830 can selectively include a nozzle 831 or a diffuser 832, and each component can be omitted as necessary. The injection pipe 830 can mix the chemical liquid having a first flow with air having a second flow and discharge it to the outside, and can omit or include various components depending on the purpose of injecting the fluid.

[0149] The steel wire 850 may be a structure provided in the center of a fluid movement path such as the internal conduit 810, the injection pipe 830, etc., to reduce the spray cross-sectional area of ​​the fluid and generate a vortex flow inside. The steel wire 850 is inserted into the conduit and can move freely, but some ends can be kept fixed and other ends can be kept moving freely by a support structure 860, etc. The steel wire 850 can be slidably inserted and connected in the opposite direction to the fluid movement path of the internal conduit 810. The steel wire 850 can be defined as an insertion structure, which is a structure inserted and connected from the outside.

[0150] The support structure 860 can take the form of a fastening screw, as long as it is capable of restricting the movement of the steel wire 850, but may also take the form of multiple rings so as not to restrict the flow of fluid.

[0151] The support structure 860 is a structure that is attached to the surface of the steel wire 850 and supports the steel wire, and can include an inner ring 861 that surrounds the steel wire, an outer ring 863 that is attached to the surface of the injection pipe, a ring connecting portion 862, etc.

[0152] The support structure 860 may be modified in various ways in terms of the number of ring joints 862 or the thicknesses of the inner ring 861 and the outer ring 863, taking into consideration the flow of fluid. The inner ring 861 may be a flexible ring that is detachably joined to the surface of the steel wire, and the outer ring 863 may be a flexible ring that is pressed into and joined to the inner surface of the injection pipe 830, but is not limited thereto.

[0153] The support structure 860 can be placed only at the end where the fluid is sprayed to increase the vibration effect of the steel wire 850, and multiple support structures can be made in the same or different sizes for convenience in response to the user's pushing.

[0154] FIG. 15 is for explaining the structure of the agricultural fogger with the steel wire inserted therein, and the internal structure of the agricultural fogger and the flow of the chemical solution are not limited thereto.
