[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] Referring to Figures 1 and 2, the mobile ozone disinfection device 100 of this embodiment includes a mobile base 10, a water tank assembly 20, an ozone assembly 30, an atomizer 40, and a fan assembly 50. The mobile base 10 serves as the mobile structure for the mobile ozone disinfection device 100, facilitating its overall movement. The water tank assembly 20 is disposed on the mobile base 10 and has a first cavity 211 for storing the liquid to be sprayed, such as water. The ozone assembly 30 is disposed on the water tank assembly 20 and includes an ozone gas source 31 and a gas-liquid mixing valve 32. The ozone gas source 31 provides ozone gas, and the gas-liquid mixing valve 32 is disposed within the first cavity 211, in fluid communication with the ozone gas source 31, and is used to mix the ozone gas with the liquid within the first cavity 211. Atomizer 40 is disposed in the first cavity 211 and is used to atomize the liquid containing ozone in the first cavity 211 into vapor. Fan assembly 50 is connected to water tank assembly 20 and is used to draw out the vapor from the first cavity 211 and blow it toward the crops to be disinfected in the greenhouse.

[0022] The mobile ozone disinfection device 100 of this application embodiment, through the above-described structural design, can move around the ground of the greenhouse to effectively repel and disinfect the middle and lower parts of the crops (especially the dense canopy areas). On the other hand, by using ozone gas dissolved in water and forming atomized mist sprayed onto the crops, the ozone mist spraying process is more uniform and delicate. In addition to improving the insect repellent and disinfection effect, it can also reduce drug residues on the crop surface, making crop cultivation greener and healthier.

[0023] The aforementioned mobile base 10 includes a base 11, a drive unit 12, a primary track 13, and an auxiliary track 14. The base 11 is used to mount the water tank assembly 20, and the drive unit 12 is disposed on the base 11. As an example, the drive unit 12 can be a motor. The primary track 13 and the auxiliary track 14 are respectively connected to the drive unit 12, which drives the primary track 13 and the auxiliary track 14 to move, enabling the entire mobile base 10 to move. In some examples, the auxiliary track 14 can rotate relative to the base 11 to adjust its tilt angle relative to the base 11, adapting to complex ground conditions and improving passability. Of course, in other examples, the mobile base 10 may only have the primary track 13 without the auxiliary track 14 to simplify the overall structure and reduce production costs.

[0024] In this embodiment, the mobile base 10 adopts a tracked structure, which can adapt to more types of ground environments, such as hard cement ground, muddy ground, swampy ground, flat ground, or uneven ground, thereby enhancing the environmental mobility of the mobile ozone disinfection equipment 100. In other embodiments, the mobile base 10 may adopt other structures, such as a wheeled rolling structure, a multi-legged crawling structure, etc.

[0025] The water tank assembly 20 described above includes a tank body 21. The tank body 21 has a first cavity 211 and a first opening 212. The first cavity 211 is used to store liquid, and the first opening 212 connects the first cavity 211 to the outside. The first opening 212 is used for the installation of a fan assembly 50, so that the vapor in the first cavity 211 can pass through the first opening 212 to the fan assembly 50, and then be sprayed from the fan assembly 50 onto the crops in the greenhouse to repel insects and kill viruses. In some embodiments, the tank body 21 also has a second opening 213, which connects the first cavity 211 to the outside and is used for the user to add liquid into the first cavity 211. Of course, in other embodiments, a one-way valve can be installed on the tank body instead of the second opening 213, and external water can enter the first cavity 211 through the one-way valve.

[0026] In some examples, the housing 21 is fixedly connected to the base 11, and the fan assembly 50 is fixedly connected to the housing 21 assembly. This structure helps to strengthen the structural strength of the housing 21 and the base 11. In other examples, the housing 21 is detachably connected to the base 11, and the fan assembly 50 is detachably connected to the housing 21. This structure allows for quick replacement of the housing 21, reduces the waiting time required for liquid refilling, and improves the disinfection efficiency of the mobile ozone disinfection equipment 100.

[0027] In some embodiments, the water tank assembly 20 further includes a water purifier (not shown), connected to the tank body 21. The water purifier filters the liquid added to the first cavity 211 to reduce impurities in the liquid and lower the risk of clogging of the atomizer 40. In some examples, the water purifier has a backwashing structure to achieve self-cleaning, extend the service life of the water purifier, and improve the liquid filtration effect.

[0028] In some embodiments, the water tank assembly 20 further includes a ball valve (not shown), which is disposed on the tank body 21 and connected to the water purifier. As an example, the ball valve is a one-way valve, which allows liquid to be injected into the first cavity 211 from the outside and prevents the liquid in the first cavity 211 from overflowing to the outside, thus ensuring the airtightness of the first cavity 211.

[0029] The ozone assembly 30 described above includes an ozone source 31, a gas-liquid mixing valve 32, a first solenoid valve 33, and an ozone sensor 34. The ozone source 31 is located on the outside of the housing 21 and is used to supply ozone gas into the first cavity 211. As examples, the ozone source 31 can be a pre-made ozone cylinder, facilitating replacement; alternatively, it can be an ozone generator, producing ozone gas on demand, reducing the cost and difficulty of storing ozone gas. The gas-liquid mixing valve 32 is located inside the first cavity 211, while the first solenoid valve 33 is located outside. The first solenoid valve 33 is connected between the ozone source 31 and the gas-liquid mixing valve 32 via a gas pipe. The first solenoid valve 33 is used to open or close the ozone passage to supply and stop the ozone supply. The gas-liquid mixing valve 32 is used to mix ozone gas with water, forming a gas-liquid mixture within the first cavity 211. As an example, the gas-liquid mixing valve 32 is a nanopump that introduces ozone gas into the water to form nanobubbles. An ozone sensor 34 is disposed within the first cavity 211. The ozone sensor 34 detects the concentration of ozone in the liquid, allowing for quantifiable adjustment of the ozone concentration for pest control and disinfection of crops, thus improving the precision of pest control. It is understood that the first solenoid valve 33 and the ozone sensor 34 can be electrically connected to the central processing unit 60 mentioned below to enhance the level of intelligence.

[0030] In other embodiments, the ozone component 30 also includes a pressure detector 35 connected to the ozone source 31. The pressure detector 35 is used to detect the pressure parameters of the ozone source 31 so that the user can know the ozone reserves or preparation status.

[0031] In some embodiments, the mobile ozone disinfection device 100 further includes a liquid level sensor 70, which is disposed within the first cavity 211 to detect the liquid level height within the first cavity 211, so that the user can know the liquid level height within the first cavity 211. In some embodiments, the mobile ozone disinfection device 100 further includes a central processing unit 60, which is electrically connected to the liquid level sensor 70. The central processing unit 60 determines whether to issue a liquid level warning signal based on the liquid level height data obtained by the liquid level sensor 70.

[0032] Of course, the ball valve described above can also be a solenoid valve. The solenoid valve is electrically connected to the central processing unit 60. The central processing unit 60 can control the opening or closing of the solenoid valve based on the liquid level data obtained by the liquid level sensor 70, so as to achieve programmed control of liquid replenishment. In some embodiments, the central processing unit 60 is electrically connected to the pressure detector 35 to obtain the pressure parameters of the ozone source 31, and determines whether to issue an ozone pressure warning signal based on the pressure parameters.

[0033] Regarding the aforementioned atomizer 40 and fan assembly 50, the atomizer 40 is disposed within the first cavity 211 of the housing 21. Specifically, the atomizer 40 is positioned near the bottom of the first cavity 211. The atomizer 40 is used to atomize the liquid containing ozone to form ozone vapor. The ozone vapor is distributed at the top of the first cavity 211. The first opening 212 of the housing 21 is located near the top of the housing 21 to facilitate the extraction of the ozone vapor and its blowing towards the crops. As an example, the atomizer 40 is an ultrasonic atomizer 40, which can atomize the liquid containing ozone into water droplets (water mist) with a diameter of up to micrometers. This facilitates the movement of the ozone vapor in the fan assembly 50 and the outside air. The smaller diameter and lighter weight of the water droplets allow them to adhere more evenly to the surface of the crops. Especially for leafy crops, the lightweight ozone vapor has stronger penetrability and can penetrate deeper into the dense canopy of the crops to achieve insect repellency and disinfection. The fan assembly 50 can also be electrically connected to the central processing unit 60 to enable the central processing unit 60 to perform programmed control of the fan assembly 50.

[0034] In some embodiments, the fan assembly 50 includes a fan 51 and a duct 52. The fan 51 is disposed at the first opening 212 and is fixedly or detachably connected to the housing 21. The two ends of the duct 52 are a first end 521 and a second end 522, respectively. The first end 521 of the duct 52 is connected to the fan 51, and the second end 522 of the duct 52 communicates with the outside. The fan 51 is used to draw ozone vapor from the first cavity 211 into the duct 52 for ozone vapor to be sprayed out. As an example, the fan 51 is an axial flow fan. As an example, the number of fans 51 can also be two, with the two fans 51 respectively disposed at the first end 521 and the second end 522 of the duct 52. This can further enhance the airflow dynamics within the duct 52, which is beneficial for enhancing the movement of the ozone vapor.

[0035] Compared to existing technologies that use a pump to draw ozone-containing liquid into pipe 52 and then spray it out through a nozzle at the end of pipe 52, pipe 52 is filled with liquid, resulting in greater stress on pipe 52 and difficulty in spraying nano-sized water mist from the nozzle at the end of pipe 52, leading to poor disinfection effect, this application uses an ultrasonic atomizer 40 located inside the housing 21. This atomizes nano-sized ozone vapor in the first cavity 211, and then the fan 51 draws the ozone vapor into pipe 52 and blows it out to the outside. On the one hand, the nano-sized vapor has a better disinfection effect on crops; on the other hand, the vapor moving inside pipe 52 is lightweight, significantly reducing the stress on pipe 52 and helping to extend its lifespan. Furthermore, it is more flexible when used in conjunction with the robotic arm 80 mentioned below.

[0036] In some embodiments, the aforementioned pipe 52 may be a rigid pipe 52, which is fixed relative to the housing 21. In other embodiments, referring to Figure 1, the pipe 52 may be a flexible hose, which has good flexibility and extensibility. The mobile ozone disinfection device 100 also includes a robotic arm 80, one end of which is mounted on the base 11 of the mobile base 10, and the other end of which can move freely in space relative to the base 11. The first end 521 of the flexible hose is connected to the fan 51, and the second end 522 of the flexible hose is connected to the other end of the robotic arm 80 to follow the movement of the robotic arm 80. By adding the robotic arm 80 structure, the flexible hose can spray ozone mist at different locations to repel and disinfect crops at different heights or different height parts of the same crop, further improving the disinfection effect. In some embodiments, the robotic arm 80 may be electrically connected to the central processing unit 60, so that the robotic arm 80 is controlled by the program of the central processing unit 60 to realize intelligent spraying of ozone mist.

[0037] In some embodiments, the mobile ozone disinfection device 100 further includes a camera assembly 90, which is disposed at the end of the robotic arm 80. The camera assembly 90 is electrically connected to the central processing unit 60 and the robotic arm 80. The camera assembly 90 is used to acquire real-time image data and transmit the real-time image data to the central processing unit 60 so that the central processing unit 60 can control the movement of the robotic arm 80.

[0038] This application provides another embodiment of a greenhouse disinfection system. The greenhouse disinfection system includes a greenhouse sensor and the aforementioned mobile ozone disinfection device 100. The greenhouse sensor establishes a communication connection with the mobile ozone disinfection device 100. The greenhouse sensor is used to detect ozone parameters inside the greenhouse and transmit the ozone parameters to the mobile ozone disinfection device 100. For the specific structure and function of the mobile ozone disinfection device 100, please refer to the above embodiments, which will not be repeated here.

[0039] The mobile ozone disinfection device 100 of this application embodiment, by being designed as a ground-mobile structure, is beneficial for effectively repelling and disinfecting the middle and lower parts of crops and dense areas of crop canopy in greenhouses, thus improving the disinfection effect. It uses ozone gas dissolved in water as a disinfectant, and atomizes it using an ultrasonic atomizer 40 to form ozone mist. This mist is small in size and light in weight, with stronger penetrating power, improving the insect repelling and disinfection effect while reducing pesticide residue on the crop surface, making crop cultivation greener and healthier. The use of a fan assembly 50 to spray ozone mist enhances its kinetic energy, making it easier to reach and adsorb onto the crop surface. The structure of a flexible hose and a robotic arm 80 allows ozone mist to be sprayed at different heights to disinfect different parts of the crop, improving practicality. A camera assembly 90 is electrically connected to a central processing unit 60 and a robotic arm 80, enabling the central processing unit 60 to control the movement of the robotic arm 80 based on real-time images captured by the camera assembly 90, further enhancing the intelligence level of the mobile ozone disinfection device 100.

[0040] The above description is merely an embodiment of this application and does not limit the patent scope of this application.
