In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0028] In the related art, for ozone disinfection, usually large equipment is required to achieve the transportation of ozone. On the one hand, due to the need for long-distance transportation, this will reduce the content of ozone, resulting in unsatisfactory disinfection effect and high disinfection cost. Especially for the facility space, the overall space is limited, and how to achieve efficient and high-quality disinfection is an important issue that needs to be solved in the industry.

[0029] Regarding the problems in the related art, such as Figure 1As described above, the present invention provides a small ozone sterilization plant protection device, which includes a housing 1, an ozone preparation component 2, a diffusion component 3 and a control component 4; a chamber 11 is formed inside the housing 1, and an air inlet 12 is opened on the housing 1, and the air inlet 12 communicates with the chamber 11; the ozone preparation component 2 is arranged inside the chamber 11, and the ozone preparation component 2 is used to prepare ozone; the diffusion component 3 includes a fan 37, a communication conduit 35 and a plurality of air guide plates. A ventilation hole is formed in the middle of each air guide plate, and the plurality of air guide plates are arranged at intervals in the vertical direction, so that the plurality of ventilation holes are stacked to form a diffusion channel, and the fan 37 is arranged at the bottom of the diffusion channel; one end of the communication conduit 35 is communicated with the chamber 11, and the other end of the communication conduit 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, the ozone preparation component 2 and the fan 37 are both electrically connected to the control component 4, and the control component 4 controls the actions of the ozone preparation component 2 and the fan 37. After ozone is generated, it needs to be transmitted and diffused as soon as possible so as to achieve the purpose of killing plant diseases and pests. In this embodiment, the generated ozone is directly diffused through the bottom diffusion component 3, which can improve the sterilization efficiency and quality, and the overall miniaturized and compact setting makes the device easy to install.

[0030] 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 closed chamber 11 is formed inside the metal housing 1, and the space inside the chamber 11 is used for installing the ozone preparation component 2. The ozone preparation component 2 is connected to an external electronic control system, so as to continuously generate ozone.

[0031] Among them, the gap space between adjacent air guide plates communicates with the diffusion channel, and the ozone in the diffusion channel can diffuse outward through the interval space of each layer, which can improve the uniformity of diffusion and the efficiency of ozone diffusion. And for ozone preparation, equipment such as an ozone generator 22 can be used to prepare ozone. The prepared ozone is input into the diffusion channel through the communication conduit 35, and the ozone is diffused into the external space through the diffusion channel.

[0032] In order to improve the diffusion efficiency and uniformity, in this embodiment, the fan 37 is used in cooperation with a plurality of air guide plates to achieve diffusion. It speeds up the flow rate of ozone through the fan 37, and the diffusion channel communicates with the interval space between adjacent air guide plates, so that ozone can quickly diffuse outward from the interval space, realizing the efficient diffusion of ozone.

[0033] It is understandable that when using ozone to kill pests and diseases on plants, it is necessary to ensure the concentration of ozone. During the transmission process of ozone, the extension of the transmission path will cause ozone loss during transmission, resulting in a decrease in the ozone concentration, which will affect the disinfection effect. Of course, in some conventional solutions, the impact of the transmission path is solved by increasing the initial transmitted ozone concentration, which will lead to an increase in the disinfection cost and require a larger power ozone preparation device. And these methods all require a large installation space for equipment, which is particularly disadvantageous for installations with a small setting space. The ozone sterilization device provided in this embodiment has a small overall structure, which does not occupy too much space and is conducive to installation. And through the setting of the diffusion component 3, it can achieve rapid diffusion of ozone, improve the efficiency of ozone diffusion, greatly shorten the transmission path of ozone, and improve the quality of ozone disinfection.

[0034] Specifically, the ventilation holes on each air guide plate are configured as circular holes, and the circular holes on each air guide plate are concentrically arranged. When the fan 37 blows ozone to move at high speed, it can flow in the gap space between adjacent air guide plates and then flow out from the gap space. This way can avoid the aggregation of ozone, make the ozone distribution more uniform, allow ozone to diffuse more evenly in the entire treatment area, contribute to improving the treatment effect of ozone, and can better kill pests and diseases.

[0035] Combined with the above embodiments, a hook 5 is provided at the top of the housing 1. The technical solution provided by the present invention is a small disinfection device. In this embodiment, through the setting of the hook 5, the overall installation of the device is more convenient and can achieve rapid installation.

[0036] Specifically, one end of the hook 5 is connected to the middle position of the top surface of the housing 1 through a flange plate. The hook 5 can be connected to other structures in the facility space, so that the overall device is located in the working area and realizes the diffusion and disinfection of ozone through the ozone preparation component 2 and the diffusion component 3.

[0037] As Figure 3 shown, in specific applications, the overall height D1 of the device is set to 900 mm. That is, the maximum height D1 of the device in the vertical direction is 900 mm, and the overall maximum width D6 is 436 mm. It can be seen that the overall device occupies a small space. During specific installation, the overall device is connected through a lifting component and is located more than 1 meter above the crops in the environment, so that the ozone in the diffusion component 3 can quickly contact the crops after diffusion, thereby realizing the rapid killing of pests and diseases.

[0038] Combined with the above embodiments, a filter element is provided in the air inlet 12, and the filter element is used to filter the gas entering the chamber 11. During the continuous ozone preparation and disinfection process, air needs to be continuously input. In this embodiment, by setting a filter element at the position of the air inlet 12, the filtration of the gas can be effectively achieved, thereby improving the overall service life.

[0039] Specifically, one end of the filter element is provided with a connection end, and a mounting port is correspondingly provided at the position of the air inlet 12. The connection end is cooperatively connected with the mounting port to realize the installation of the filter element, so that the space of the chamber 11 inside the housing 1 is communicated with the external environment through the filter element. This method can effectively filter out dust, water vapor, etc. in the air, maintain the cleanliness of the environment in the chamber 11, and thus improve the service life of the equipment. For example, mounting posts are provided at the air inlet position, and correspondingly, a mounting hole is provided in the middle of the filter element. The mounting hole is cooperatively installed with the mounting posts, so that the external gas is filtered by the filter element when entering the chamber 11. Among them, the specific structure of the filter element can adopt an air filter element and various conventional filter element structures. Therefore, the specific structure of the filter element will not be elaborated herein.

[0040] Combined with the above embodiments, the ozone sterilization plant protection device further 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, and the signal output module 42, the ozone preparation component 2, and the fan 37 are all electrically connected to the signal input module 41. The signal output module 42 is used for the series connection of multiple devices, and the signal input module 41 is used for inputting control signals to control the actions of the ozone preparation component 2 and the fan 37. During the ozone disinfection operation, it is necessary to control the operation of each device in real time. In this embodiment, through the setting of the controller 43, the signal input module 41, and the signal output module 42, the complexity of control can be simplified. Especially when multiple devices are operating, the overall equipment cost can be reduced, and the control difficulty of each device can be simplified.

[0041] Specifically, as Figure 2 shown, the controller 43 includes a main body box 431 and an electronic control board 432. The electronic control board 432 is arranged inside the main body box 431. One side of the electronic control board 432 is provided with a power supply access 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, so as to realize the transmission of signals. The sensor interface 434 can be connected to an external environmental monitoring system, so as to realize the sensing of the external environment. The electronic control board 432 is used to process the sensed information and the input information, so as to issue control signals. The signal input module 41 can realize the input of control signals and control the working or stopping of the actuators (the ozone preparation component 2 and the fan 37).

[0042] Furthermore, since the overall structure of the ozone sterilization plant protection device provided by the present invention is small and its coverage range is limited, in actual use, multiple devices need to be installed in a facility space or a greenhouse. The devices are connected in series through the signal input module 41 and the signal output module 42, so that one controller 43 can control multiple devices, reducing the 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 through a wire, and the signal output module 42 of the second device is connected to the signal input module 41 of the third device, thus realizing the series connection of the three devices and facilitating the control of the controller 43.

[0043] Specifically, firmware connection parts are provided on both the top and bottom of the main body box 431. The firmware connection parts are used for external connection and fixation, so that the controller 43 can be independent of the device and be located on other installation and fixation parts separately. For example, a control board is installed in the facility space, and the controller 43 is fixedly connected to the control board by bolts.

[0044] Among them, the sensor interface 434 can be connected to greenhouse sensors, light sensors, CO2 concentration sensors, ozone concentration sensors, etc. It can transmit the collected greenhouse environment data to the control circuit board and output it to the small ozone sterilization plant protection device in the facility space to realize the control of the device. A wireless communication module is installed on the electronic control board 432, which realizes real-time data transmission and remote control of the device through networks such as GPRS, WiFi, 5G / 4G.

[0045] Combined with the above embodiments, the ozone preparation component 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 high-voltage current required by the ozone generator 22. In this example, by selecting the high-voltage ozone generator 22, it can generate a higher concentration of ozone, and its overall structure is small, and it can be installed in the chamber 11 to realize ozone preparation.

[0046] Specifically, the high-voltage discharge type ozone generator 22 can generate a higher 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.

[0047] It should be understood that in the present invention, high voltage refers to a voltage exceeding 220V. That is, the high-voltage transformer 21 can convert the mains voltage into a higher voltage.

[0048] Combined with the above embodiments, the air deflector includes a first air deflector disk 31, a second air deflector disk 32, a third air deflector disk 33, and a fourth air deflector disk 34 that are arranged in sequence from top to bottom and have gradually decreasing diameters; a first gap 301 is formed between the first air deflector disk 31 and the second air deflector disk 32, a second gap 302 is formed between the second air deflector disk 32 and the third air deflector disk 33, and a third gap 303 is formed between the third air deflector disk 33 and the fourth air deflector disk 34; wherein, the second gap 302 is greater than the first gap 301, and the first gap 301 is greater than the third gap 303. During the process of ozone diffusion, uniform diffusion is required to avoid local accumulation. In this embodiment, through the setting of the three gaps, the ozone can be diffused more uniformly, avoiding local accumulation.

[0049] Specifically, the four air deflector disks are of an overall circular disk structure, and the first gap 301, the second gap 302, and the third gap 303 are all communicated with the diffusion channel. Ozone flows upward from the bottom of the diffusion channel and flows out through the three gaps during the flowing process. This setting of the three gaps stacked on top of each other can further improve the uniformity of ozone dispersion.

[0050] It can be understood that ozone flows rapidly under the action of the fan 37 and gradually spreads during the rising process. In this embodiment, the distance of the second gap 302 is the largest, which can prevent ozone from accumulating during the rising process, enable timely diffusion, and through the setting of different intervals, the turbulence phenomenon of the air flow can be reduced, the flow stability of the gas can be improved, and the losses or non-uniformities that may be caused by too fast flow rate can be reduced. Further, by enlarging the second gap 302, the resistance of the air flow can be effectively reduced, avoiding excessive pressure loss caused by the air flow passing through a narrow space, and improving the energy efficiency and economy of the system.

[0051] When specifically setting, the distance between the first gaps 301 is 14 mm, the distance of the second gap 302 is 21 mm, and the distance of the third gap 303 is 13 mm. Through the quantitative limitation, the transmission process of ozone is more stable and the uniformity is better.

[0052] Combined with the above embodiments, a first guiding portion 311 is provided at the edge of the first air guiding disc 31, and the first guiding portion 311 extends obliquely upward. A second guiding portion 321 is provided at the edge of the surface of the second air guiding disc 32 opposite to the first air guiding disc 31, and a third guiding portion 322 is provided at the edge of the surface of the second air guiding disc 32 opposite to the third air guiding disc 33. The second guiding portion 321 extends obliquely upward, and the third guiding portion 322 extends obliquely downward; a fourth guiding portion 331 is provided at the edge of the third air guiding disc 33, and the fourth guiding portion 331 is arranged obliquely downward. A fifth guiding portion 341 is provided at the edge of the fourth air guiding disc 34, and the fifth guiding portion 341 is arranged obliquely downward; wherein, the first guiding portion 311 cooperates with the second guiding portion 321 to make the opening of the first gap 301 incline upward, the third guiding portion 322 cooperates with the fourth guiding portion 331 to make the opening of the second gap 302 incline downward, and the fourth guiding portion 331 cooperates with the fifth guiding portion 341 to make the opening of the third gap 303 incline downward. After the ozone flows through the gap, it flows out from the edge of the gap. In this embodiment, by defining the guiding structure at the edge, the distribution of ozone can be further optimized, and the uniformity of ozone distribution can be improved.

[0053] Specifically, the main structures of the first air guiding disc 31, the second air guiding disc 32 and the third air guiding disc 33 are horizontally arranged. The first guiding portion 311 forms an angle with the first air guiding disc 31 and is arranged vertically upward. The second guiding portion 321 forms an angle with the second air guiding disc 32 and is arranged vertically upward. The third guiding portion 322 forms an angle with the second guiding disc and is arranged vertically downward. That is, guiding portions with opposite directions are provided on the two surfaces of the second guiding disc, so as to realize the guiding of gas flow with the corresponding cooperating guiding portions.

[0054] It can be understood that since ozone is a reactive gas and is prone to react with other substances, if the gas stays in the system for too long, it may decompose or be lost. Through the inclined design, it can ensure the smooth flow of the gas, avoid the phenomenon of gas retention and excessive concentration in some parts of the system, and thus improve the efficiency of ozone delivery. Specifically, by arranging the first guiding portion 311 and the second guiding portion 321 obliquely upward, it helps to promote the natural flow and distribution of the air flow. The flow direction of the gas can avoid the retention or local accumulation of the air flow in the system through the inclined design, and ensure that the ozone gas can be evenly distributed throughout the system or the reaction area. For the downward flow of the third guiding portion 322, the fourth guiding portion 331 and the fifth guiding portion 341, it helps to form a natural convection cycle of the gas in the system. Through such a flow pattern, the ozone can be more evenly distributed in the system, enhancing the contact and reaction efficiency of the gas in different regions.

[0055] Combined with the above embodiments, the first guiding portion 311 is parallel to the second guiding portion 321, and the third guiding portion 322 is parallel to the fourth guiding portion 331. Such a parallel arrangement can effectively reduce the wind resistance during the flow process and reduce the overall loss of the system.

[0056] Specifically, the first guiding portion 311 and the second guiding portion 321 are flanging structures that slope upward. The connection positions of the flanging structures with their respective air guiding discs are smooth curved surfaces. This way can make the overall structural strength of the air guiding disc higher and make the overall structure more stable.

[0057] When specifically setting, as Figure 3 shown, the inclination angle R1 of the first guiding portion 311 and the inclination angle R2 of the second guiding portion 321 are both 10 degrees, the inclination angle R3 of the third guiding portion 322 and the inclination angle R4 of the fourth guiding portion 331 are both 20 degrees, and the inclination angle R5 of the fifth guiding portion 341 is 30 degrees. By limiting the inclination angles, the ozone diffused into the external environment can achieve the optimal balance among uniformity, fluidity, and ozone loss, realizing efficient and uniform diffusion of ozone.

[0058] In some embodiments, a connecting bottom plate 36 is provided at the bottom of the fourth air guiding disc 34. An installation through hole is provided in the middle of the connecting bottom plate 36, and the installation through hole is concentrically arranged with the diffusion channel. The fan 37 is arranged in the installation channel; wherein, a protective cover 38 with a mesh structure is further provided below the connecting bottom plate 36. There is a accommodation gap between the protective cover 38 and the connecting bottom plate 36, and one end port of the connecting conduit 35 is located in the accommodation gap. When ozone is diffused, the fan 37 is needed to achieve efficient diffusion. In this embodiment, through the setting of the connecting bottom plate 36, the connection stability of the fan 37 is higher, and through the setting of the protective cover 38, the overall service life of the equipment can be improved.

[0059] Specifically, the main body of the fan 37 is located above the connecting conduit 35. The fan 37 is specifically a backward centrifugal fan 37, which is fixed in the installation through hole of the connecting bottom plate 36 by bolts, and can blow ozone into the diffusion channel through the connecting conduit 35, thereby realizing the rapid diffusion of ozone in the gap.

[0060] Among them, the protective cover 38 is preferably a stainless steel disc-shaped isolation net, which is installed at a position 15 mm below the connecting bottom plate 36 and is installed at the air inlet of the engine room chassis by means of bolt connection to prevent branches, leaves, etc. of crops from entering the fan 37 and damaging the fan 37.

By defining the dimensions, the device can balance the functions of small size, high efficiency, and uniform ozone diffusion.

[0062] As Figure 4 shown, in the second aspect of the present invention, a control system for a small ozone sterilization and plant protection device provided based on any one of the above embodiments is provided, including a remote control device communicatively connected to the control component 4, and the remote control device is used to execute the following control method: Step S10: Obtain the external environment data of the small ozone sterilization and plant protection device. Specifically, a control and external environment data acquisition component is provided in the control system. Through the acquisition component, the data acquisition of the external environment can be realized, and through the controller 43, the storage and processing of the data can be realized.

[0063] Specifically, the acquisition component may include devices such as an oil temperature acquisition sensor, a humidity acquisition sensor, and a light intensity sensor, which can detect the data of the external environment of the device in real time and give real-time feedback.

[0064] Step S20: Select a corresponding working mode based on the obtained external environment data. Specifically, multiple working models are stored in the controller 43 or the processor. Each working model corresponds to a working mode, and each working mode includes the following preset parameters: the start of the fan 37, the wind force intensity of the fan 37, the ozone release amount of the ozone preparation component 2, and the working period of the plant protection device. In this way, when based on the environmental data, the corresponding working mode can be directly called, so as to realize the control of parameters such as the ozone preparation component 2 and the wind force of the fan 37.

[0065] 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 device according to the preset wind force intensity. Based on the foregoing, after the working mode is determined, the ozone release amount of the ozone preparation component 2, the wind force intensity of the fan 37, the plant protection time period, etc. are correspondingly determined, and the control component 4 can control the corresponding ozone preparation component 2 and the fan 37 to operate.

[0066] Furthermore, the user can send control information to the above-mentioned controller 43 through the mobile phone APP to realize the remote adjustment of the air volume of the fan 37, the ozone release amount, the start and stop of the device, and the working period of the small ozone sterilization and plant protection device in the facility space, as well as the real-time acquisition of environmental data such as temperature, humidity, light intensity, CO2 concentration, and ozone concentration.

[0067] Specifically, the working process of the small ozone sterilization plant protection device is as follows: Hang and install the device on the top of the facility greenhouse and connect it to the 220V power supply. Then, download and install the mobile APP of the device, scan the QR code on the device to complete the registration and remote control of the device.

[0068] First, environmental data collection is achieved through the sensor structure. After the device is powered on, sensors such as temperature, humidity, and light intensity sensors can automatically collect environmental data in the facility 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 the mobile APP and remotely adjust the working mode of the device according to the environmental data values.

[0069] Next, based on the feedback information, plant protection operations are started: Users remotely control the working mode of the plant protection device through the mobile APP, including the startup of the device fan 37, the wind force intensity of the fan 37, the ozone release amount of the ozone preparation component 2, the working period of the plant protection device, etc. Among them, the setting of the device working mode is mainly based on factors such as the type of crops planted in the greenhouse, the area of the greenhouse, the growth period of the crops, the type and severity of diseases, etc. Ozone is generated according to the set mode, and the device evenly diffuses the ozone to the entire space of the facility through the air deflector. Finally, when the device receives the shutdown command, it stops working. Thus, the plant protection operation of the plant protection device in the entire greenhouse is completed.

[0070] Through the description of the above embodiments, those skilled in the art can clearly understand that through the setting of the ozone preparation component 2 in each embodiment, the device can generate ozone, and through the diffusion component 3, rapid and uniform diffusion of ozone can be achieved to improve the efficiency and effect of ozone sterilization. Moreover, the overall structure is compact, the overall size is small, it is easy to carry, the preparation cost is low, and it is suitable for large-scale promotion in the facility. Further, through the setting of the separate controller 43, it can simplify the control and make the overall control more convenient.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
