[0032] In related technologies, ozone disinfection typically requires large equipment for ozone delivery. This method, due to the need for long-distance delivery, reduces ozone concentration, leading to less effective disinfection and higher costs. Especially in facilities with limited space, achieving efficient and high-quality disinfection is a crucial issue that the industry needs to address.

[0033] Regarding the problems in related technologies, such as Figure 1The present invention provides a small ozone sterilization and plant protection device, comprising a shell 1, an ozone preparation component 2, a diffusion component 3, and a control component 4; a chamber 11 is formed inside the shell 1, and an air inlet 12 is provided on the shell 1, which is connected to the chamber 11; the ozone preparation component 2 is disposed in the chamber 11 and is used to prepare ozone; the diffusion component 3 includes a fan 37, a connecting duct 35, and multiple air guide plates, each air guide plate having a ventilation hole in the middle, and the multiple air guide plates are arranged vertically at intervals so that the multiple ventilation holes are stacked to form a diffusion channel, and the fan 37 is located at the bottom of the diffusion channel; one end of the connecting duct 35 is connected to the chamber 11, and the other end of the connecting duct 35 is located at the bottom of the diffusion channel so that ozone flows out along the gap between adjacent air guide plates under the action of the fan 37; the control component 4 is electrically connected to both the ozone preparation component 2 and the fan 37, and the control component 4 controls the operation of the ozone preparation component 2 and the fan 37. After ozone is generated, it needs to be transported and diffused as soon as possible in order to achieve the purpose of eliminating plant diseases and pests. In this embodiment, the generated ozone is diffused directly through the bottom diffusion component 3, which can improve the efficiency and quality of elimination. Moreover, the overall miniaturized and compact design makes the device easy to install.

[0034] Specifically, the housing 1 is a metal housing 1, and the overall structure of the metal housing 1 is a frustum-shaped structure, that is, the diameter of the metal housing 1 gradually increases from top to bottom. A relatively sealed chamber 11 is formed inside the metal housing 1. The space inside the chamber 11 is used for the installation of the ozone generation component 2. The ozone generation component 2 is connected to an external electronic control system, so that it can continuously generate ozone.

[0035] The gaps between adjacent air guide plates are connected to the diffusion channel, allowing ozone within the diffusion channel to diffuse outwards through the gaps between each layer. This improves the uniformity and efficiency of ozone diffusion. Furthermore, ozone can be generated using equipment such as an ozone generator 22. The generated ozone is then input into the diffusion channel through a connecting conduit 35 and diffused into the external space via the diffusion channel.

[0036] To improve the efficiency and uniformity of diffusion, this embodiment employs a fan 37 in conjunction with multiple air guide plates to achieve diffusion. The fan 37 accelerates the flow of ozone, and the diffusion channel connects with the space between adjacent air guide plates, allowing ozone to rapidly diffuse outward from this space, thus achieving highly efficient ozone diffusion.

[0037] It is understandable that when using ozone to control plant pests and diseases, it is necessary to ensure the ozone concentration. However, during ozone transmission, the extended transmission path leads to ozone loss, resulting in a decrease in ozone concentration, which affects the effectiveness of the control. Some conventional solutions address the transmission path issue by increasing the initial ozone concentration, but this increases the cost of control and requires a more powerful ozone generator. Furthermore, these methods all require a large installation space, which is particularly unfavorable for setups with limited space. The ozone sterilization device provided in this embodiment has a compact overall structure. This structure does not occupy much space, is easy to install, and through the diffusion component 3, it enables rapid ozone diffusion, improving ozone diffusion efficiency, significantly shortening the ozone transmission path, and improving the quality of ozone sterilization.

[0038] In the specific setup, the ventilation holes on each air guide plate are circular holes, and the circular holes on each air guide plate are concentrically arranged. When the fan 37 blows ozone at high speed, it can flow in the gap space between adjacent air guide plates, thus flowing outward from the gap space. This method can avoid the accumulation of ozone, making the ozone distribution more uniform, allowing the ozone to diffuse more evenly throughout the entire treatment area, which helps to improve the ozone treatment effect and better eliminate it.

[0039] In conjunction with the above embodiments, a hook 5 is provided on the top of the housing 1. The technical solution provided by the present invention is a small-scale disinfection device. In this embodiment, the hook 5 makes the overall installation of the device more convenient and enables rapid installation.

[0040] Specifically, one end of the hook 5 is connected to the middle of the top surface of the housing 1 via a flange. The hook 5 can be connected to other structures within the facility space, so that the entire device is located within the working area and ozone diffusion and disinfection are achieved through the ozone preparation component 2 and the diffusion component 3.

[0041] like Figure 3 As shown, in practical applications, the overall height D1 of the device is set to 900mm, meaning the maximum vertical height D1 is 900mm, and the maximum overall width D6 is 436mm. It can be seen that the device occupies relatively little space. During installation, the entire device is connected via a hoisting component, positioning it at least 1 meter above the crops in the environment. This allows the ozone within the diffusion component 3 to quickly contact the crops after diffusion, thus achieving rapid pest and disease control.

[0042] In conjunction with the above embodiments, a filter element is provided inside the air inlet 12 to filter the gas entering the chamber 11. During continuous ozone production and disinfection, a continuous supply of air is required. This embodiment effectively filters the gas by placing a filter element at the air inlet 12, thereby improving the overall service life.

[0043] Specifically, one end of the filter element has a connecting end, corresponding to an installation port at the air inlet 12. The connecting end and the installation port are connected to each other, thereby installing the filter element and allowing the chamber 11 inside the housing 1 to communicate with the external environment through the filter element. This method can effectively filter out dust, moisture, and other pollutants from the air, maintaining the cleanliness of the environment inside the chamber 11 and thus extending the service life of the equipment. For example, an installation post is provided at the air inlet, corresponding to an installation hole in the middle of the filter element. The installation hole and the installation post are fitted together, allowing external air to be filtered by the filter element when entering the chamber 11. The specific structure of the filter element can be an air filter element, as well as various conventional filter element structures. Therefore, the specific structure of the filter element will not be described in detail.

[0044] In conjunction with the above embodiments, the ozone sterilization and plant protection device also includes a control component 4. The control component 4 includes a controller 43, a signal input module 41, and a signal output module 42. The signal input module 41 is electrically connected to the controller 43. The signal output module 42, the ozone generation component 2, and the fan 37 are all electrically connected to the signal input module 41. The signal output module 42 is used for connecting multiple devices in series, and the signal input module 41 is used to input control signals to control the operation of the ozone generation component 2 and the fan 37. During ozone sterilization operations, it is necessary to control the operation of each device in real time. This embodiment, through the design of the controller 43, the signal input module 41, and the signal output module 42, simplifies the complexity of control, especially when multiple devices are operating, reducing the overall equipment cost and simplifying the control difficulty of each device.

[0045] Specifically, such as Figure 2 As shown, the controller 43 includes a main body box 431 and an electronic control board 432. The electronic control board 432 is located inside the main body box 431. One side of the electronic control board 432 is provided with a power input port 433 and a sensor interface 434, and the other side of the electronic control board 432 is provided with an electrical connection port 435. The electrical connection port 435 is connected to the signal input module 41 through a wire, thereby enabling signal transmission. The sensor interface 434 can be connected to an external environmental monitoring system, thereby enabling the sensing of the external environment. The electronic control board 432 is used to process the sensed information and the input information, thereby enabling the issuance of control signals. The signal input module 41 can realize the input of control signals and control the actuators (ozone generation component 2 and fan 37) to work or stop.

[0046] Furthermore, because the ozone sterilization and plant protection device provided by this invention has a compact overall structure and limited coverage, in practical applications, multiple devices need to be installed in a facility space or greenhouse. Each pair of devices is connected in series via a signal input module 41 and a signal output module 42, enabling one controller 43 to control multiple devices, reducing overall control difficulty and equipment cost. For example, if three devices are installed in a facility space, the signal output module 42 of the first device is connected to the signal input module 41 of the second device via wires, and the signal output module 42 of the second device is connected to the signal input module 41 of the third device, thus achieving series connection of the three devices, which facilitates control by the controller 43.

[0047] Specifically, fasteners are provided at the top and bottom of the main body box 431. These fasteners are used for external connection and fixation, allowing the controller 43 to be located independently of the equipment and on other mounting fixtures. For example, a control board is provided within the facility space, and the controller 43 is fixedly connected to the control board by bolts.

[0048] The sensor interface 434 can connect to greenhouse sensors, light sensors, CO2 concentration sensors, ozone concentration sensors, etc., and can transmit the collected greenhouse environmental data to the control circuit board and output it to the small ozone sterilization and plant protection device in the facility space to realize the control of the equipment. The electronic control board 432 is equipped with a wireless communication module, which realizes real-time data transmission and remote control of the equipment through GPRS, WiFi, 5G / 4G and other networks.

[0049] In conjunction with the above embodiments, the ozone generation assembly 2 includes a high-voltage transformer 21 and an ozone generator 22. The ozone generator 22 is electrically connected to the high-voltage transformer 21, and the high-voltage transformer 21 provides the required high-voltage current to the ozone generator 22. In this example, by selecting a high-voltage ozone generator 22, it is able to generate a high concentration of ozone, and its overall structure is compact, allowing it to be installed inside the chamber 11 to achieve ozone generation.

[0050] Specifically, the high-voltage discharge ozone generator 22 can produce a high concentration of ozone. It mainly uses a high-voltage electric field to generate ozone. The technology is mature and the operation is simple, which can simplify the overall operation difficulty.

[0051] It should be understood that in this invention, high voltage refers to voltages exceeding 220V, that is, the mains voltage can be converted to a higher voltage through the high voltage transformer 21.

[0052] In conjunction with the above embodiments, the air guide plate includes a first air guide plate 31, a second air guide plate 32, a third air guide plate 33, and a fourth air guide plate 34 arranged sequentially from top to bottom with gradually decreasing diameters. A first gap 301 is formed between the first air guide plate 31 and the second air guide plate 32, a second gap 302 is formed between the second air guide plate 32 and the third air guide plate 33, and a third gap 303 is formed between the third air guide plate 33 and the fourth air guide plate 34. The second gap 302 is larger than the first gap 301, and the first gap 301 is larger than the third gap 303. During ozone diffusion, uniform diffusion is required to avoid local accumulation. In this embodiment, the arrangement of three gaps enables more uniform ozone diffusion and avoids local accumulation.

[0053] Specifically, the four air guide discs are circular discs in shape, and the first gap 301, the second gap 302 and the third gap 303 are all connected to the diffusion channel. Ozone flows upward from the bottom of the diffusion channel and flows out through the three gaps during the flow. This stacked arrangement of the three gaps can further improve the uniformity of ozone dispersion.

[0054] Understandably, ozone flows rapidly under the action of fan 37 and gradually diffuses during its ascent. In this embodiment, the second gap 302 has the largest distance, which prevents ozone from accumulating during its ascent and allows for timely diffusion. Furthermore, the varying intervals reduce airflow turbulence, improve gas flow stability, and minimize potential losses or unevenness due to excessive flow velocity. Moreover, the enlarged second gap 302 effectively reduces airflow resistance, preventing excessive pressure loss due to airflow passing through confined spaces, thus improving the system's energy efficiency and economy.

[0055] Specifically, the spacing between the first gaps 301 is 14mm, the spacing between the second gaps 302 is 21mm, and the spacing between the third gaps 303 is 13mm. This quantitative limitation makes the ozone transmission process more stable and more uniform.

[0056] In conjunction with the above embodiments, the edge of the first air guide plate 31 is provided with a first guide portion 311, which extends obliquely upward; the edge of the second air guide plate 32 opposite to the first air guide plate 31 is provided with a second guide portion 321; the edge of the second air guide plate 32 opposite to the third air guide plate 33 is provided with a third guide portion 322; the second guide portion 321 extends obliquely upward, and the third guide portion 322 extends obliquely downward; the edge of the third air guide plate 33 is provided with a fourth guide portion 331, which is obliquely downward; the edge of the fourth air guide plate 34 is provided with a fifth guide portion 341, which is obliquely downward; wherein, the first guide portion 311 and the second guide portion 321 cooperate to make the opening of the first gap 301 obliquely upward; the third guide portion 322 and the fourth guide portion 331 cooperate to make the opening of the second gap 302 obliquely downward; and the fourth guide portion 331 and the fifth guide portion 341 cooperate to make the opening of the third gap 303 obliquely downward. After flowing through the gap, ozone exits from the edge of the gap. In this embodiment, the ozone distribution can be further optimized and the uniformity of ozone distribution can be improved by defining the guiding structure at the edge.

[0057] Specifically, the main structures of the first air guide plate 31, the second air guide plate 32, and the third air guide plate 33 are horizontally arranged. The first guide part 311 is at a certain angle to the first air guide plate 31 and is vertically upward. The second guide part 321 is at a certain angle to the second air guide plate 32 and is vertically upward. The third guide part 322 is at a certain angle to the second air guide plate and is vertically downward. That is, guide parts with opposite orientations are provided on both sides of the second air guide plate, so that the gas flow can be guided by the corresponding guide parts.

[0058] Understandably, since ozone is a reactive gas, it readily reacts with other substances. If the gas remains within the system for too long, it may decompose or be lost. The inclined design ensures smooth gas flow, preventing gas stagnation and excessive concentration in certain parts of the system, thereby improving ozone delivery efficiency. Specifically, by tilting the first guide section 311 and the second guide section 321 upwards, it helps promote natural airflow and distribution. The inclined design prevents airflow stagnation or localized accumulation within the system, ensuring that ozone gas is evenly distributed throughout the system or reaction area. The downward flow of the third guide section 322, the fourth guide section 331, and the fifth guide section 341 helps create natural convection circulation within the system. Through this flow pattern, ozone can be more evenly distributed within the system, enhancing gas contact and reaction efficiency in different areas.

[0059] In conjunction with the above embodiments, the first guide portion 311 is parallel to the second guide portion 321, and the third guide portion 322 and the fourth guide portion 331 are parallel. This parallel arrangement can effectively reduce wind resistance during the flow process and reduce the overall loss of the system.

[0060] Specifically, the first guide part 311 and the second guide part 321 are inclined upward curved edge structures, and the connection position between the curved edge structure and their respective air guide plates is a smooth curved surface. This method can make the overall structure of the air guide plate stronger and the overall structure more stable.

[0061] In specific settings, such as Figure 3 As shown, the tilt angles R1 and R2 of the first guide section 311 and the second guide section 321 are both 10 degrees, the tilt angles R3 and R4 of the third guide section 322 and the fourth guide section 331 are both 20 degrees, and the tilt angle R5 of the fifth guide section 341 is 30 degrees. By limiting the tilt angles, the uniformity, flowability, and ozone loss of ozone diffused into the external environment can be optimally balanced, achieving efficient and uniform ozone diffusion.

[0062] In some embodiments, the bottom of the fourth air guide plate 34 is provided with a connecting base plate 36, and the connecting base plate 36 has a mounting through hole in the middle, which is concentrically arranged with the diffusion channel. The fan 37 is located in the mounting channel. A mesh protective cover 38 is also provided below the connecting base plate 36, and there is an accommodating gap between the protective cover 38 and the connecting base plate 36. One end of the connecting duct 35 is located within the accommodating gap. Efficient diffusion of ozone requires the fan 37. In this embodiment, the connecting base plate 36 improves the stability of the fan 37 connection, and the protective cover 38 increases the overall service life of the equipment.

[0063] Specifically, the main body of the fan 37 is located above the connecting duct 35. The fan 37 is a backward centrifugal fan 37, which is fixed to the mounting through hole of the connecting base plate 36 by bolts. It can blow ozone into the diffusion channel through the connecting duct 35, thereby realizing the rapid diffusion of ozone in the gap.

[0064] The protective cover 38 is preferably a stainless steel disc-shaped isolation net. It is installed 15mm below the connecting base plate 36 and bolted to the air inlet of the nacelle chassis to prevent crop branches and leaves from entering the fan 37 and damaging it. The connecting conduit 35 is preferably a high-strength, aging-resistant plastic hose, and multiple connecting conduits 35 are provided around the circumference of the chamber 11 to achieve rapid ozone extraction from the chamber 11.

[0065] Furthermore, to ensure the overall performance of the device, such as Figure 3As shown, the height D2 of the housing 1 is 70mm, the width of the top of the housing 1 is 370mm, the height D3 between the first air guide plate 31 and the fourth air guide plate is 50mm, the height D4 between the fourth air guide plate and the protective cover 38 is 30mm, and the diameter D5 of the diffusion channel is 132mm. By limiting the dimensions, the equipment can achieve both small size and efficient, uniform ozone diffusion.

[0066] like Figure 4 As shown, a second aspect of the present invention provides a control system for a small ozone sterilization and plant protection device based on any of the above embodiments, including a remote control device communicatively connected to the control component 4, the remote control device being used to perform the following control methods:

[0067] Step S10: Acquire external environmental data of the small ozone sterilization and plant protection device. Specifically, the control system is equipped with a data acquisition component for both control and external environmental data. The acquisition component enables the acquisition of external environmental data, and the controller 43 enables the storage and processing of the data.

[0068] In specific settings, the data acquisition components may include devices such as oil temperature sensors, humidity sensors, and light intensity sensors, which can detect data from the external environment of the equipment in real time and provide real-time feedback.

[0069] Step S20: Select the corresponding working mode based on the acquired external environmental data. Specifically, multiple working models are stored in the controller 43 or processor. Each working model corresponds to a working mode. Each working mode includes the following preset parameters: start-up of the fan 37, wind speed of the fan 37, ozone release from the ozone preparation component 2, and the working period of the plant protection device. In this way, the corresponding working mode can be directly called based on environmental data, thereby realizing the control of parameters such as the ozone preparation component 2 and the wind speed of the fan 37.

[0070] Step S30: Control the small ozone sterilization and plant protection device to generate ozone according to the determined working mode, and control the fan 37 to diffuse the ozone into the external environment of the equipment according to the preset wind intensity. As mentioned above, after the working mode is determined, the ozone release amount of the ozone generating component 2, the wind intensity of the fan 37, and the plant protection time period are correspondingly determined. The control component 4 can then control the operation of the corresponding ozone generating component 2 and the fan 37.

[0071] Furthermore, users can send control information to the controller 43 via a mobile app to remotely adjust the air volume, ozone release, start / stop of the device, and working hours of the small ozone sterilization and plant protection device within the facility space, as well as collect environmental data such as temperature, humidity, light intensity, CO2 concentration, and ozone concentration in real time.

[0072] Specifically, the working process of the small ozone sterilization and plant protection device is as follows: The device is suspended and installed on the top of the greenhouse and connected to a 220V power supply. Then, the user downloads and installs the device's mobile app, scans the QR code on the device, and registers and remotely controls the device.

[0073] First, environmental data is collected through a sensor structure. After the equipment is turned on, it can automatically collect environmental data in the facility using sensors such as temperature, humidity, and light intensity, and upload the data to the plant protection machine information management system in real time. Users can view the environmental data in the facility in real time through a mobile APP and remotely adjust the working mode of the equipment according to the environmental data values.

[0074] Next, based on the feedback information, the plant protection operation begins: the user remotely controls the operating mode of the plant protection device via a mobile app, including starting the device's fan 37, controlling the fan's wind speed, adjusting the ozone release from the ozone generation component 2, and setting the device's operating time. The device's operating mode is primarily determined by factors such as the type of crops grown in the greenhouse, the greenhouse area, the crop's growth stage, and the type and severity of diseases. Ozone is generated according to the set mode, and the device evenly diffuses the ozone throughout the entire facility space via air guides. Finally, the device stops operating upon receiving a shutdown command. This completes the plant protection operation within the entire greenhouse.

[0075] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment, through the setting of the ozone preparation component 2, enables it to generate ozone, and through the diffusion component 3, enables the rapid and uniform diffusion of ozone, thereby improving the efficiency and effectiveness of ozone sterilization. Furthermore, the overall structure is compact and small, making the device easy to carry, with low manufacturing costs, suitable for large-scale deployment in facilities. Moreover, the separate controller 43 simplifies control, making overall control more convenient.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
