[0027] It should be noted that the relational terms herein, such as first and second, are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any such actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by an "includes a" statement does not exclude the existence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0028] As shown in the accompanying drawings, a convenient-to-use pesticide sprayer for rice cultivation and planting according to the present application comprises a nozzle 1, a deflector 2, a liquid pipe 3, a medicine box 4, and a support 5. Figure 1

[0029] The nozzle 1 is installed at one end of the liquid pipe 3. In terms of structure, it has several internal passage designs and a unique mouth opening configuration. The shape and diameter of the spray holes are specially optimized to ensure that the liquid is uniformly broken down into micron-sized particles when subjected to extrusion and sprayed out at a certain angle. In one example, the nozzle 1 is made of stainless steel and has five micropores arranged at different angles.

[0030] The deflector 2 is installed outside the nozzle 1 to form an additional surrounding device. This structure is compatible with the nozzle 1 and the two are closely combined together to provide a physical barrier to limit the disturbance of external factors on the dispersed medicine without affecting the release path of the medicine. Its main body presents a trumpet-shaped tapered form, gradually widening from the narrowest end near the nozzle 1 to the farthest edge; at the same time, the material is selected to be a plastic product with certain toughness and strength to achieve the function of light weight and durability. This component can guide the pesticide in the space very close to the spray port.

[0031] The liquid pipe 3 serves as a connecting component, starting from the container at the filling solution position and ending at the nozzle 1 performing the dispensing task. This long strip-shaped hose 10 is designed to be flexible without breaking or bending to affect the transmission effect, and is connected to other parts seamlessly through a quick buckle connection mode.

[0032] ​The tank 4 is used to carry a predetermined amount of mixed preparation and to supply the whole spraying mechanism with the material resource. It is installed on the top of a base structure which is convenient for transportation and supporting other accessories, and is provided with a valve control system to regulate the liquid discharge rate. For example, a common embodiment is a portable cylindrical tank with a volume of 20 liters, equipped with a flow rate regulator at the bottom to adjust the flow rate.

[0033] The support 5 bears the stability of the whole facility and assists the operator to carry the tool. Its main frame can be a metal frame structure with good compression resistance, and the top is equipped with a belt or hook to enable the user to wear the device on the body during field work to move around. Some versions may also contain a backpack.

[0034] When the above elements are combined into a unified system, the adverse consequences in windy environments can be solved. Specifically, because there is a fairing 2 around the spray site and with a size that is appropriately proportional, the degree of external airflow interference is effectively reduced, and unnecessary drift of the mist droplets that have just been sprayed before they have spread is prevented, ultimately reducing the loss of drugs and the risk of potential environmental hazards.

[0035] In an embodiment, the gap between the fairing 2 and the spray head 1 is particularly optimized in the design of a convenient-to-use pesticide sprayer for rice cultivation. Specifically, the gap between the fairing 2 and the spray head 1 is fixed at 0.1 mm to 1 mm. This setting ensures that there is a necessary gap to allow the liquid to be evenly dispersed and sprayed, and that it is close enough to inhibit external natural factors such as wind from forming an effective barrier to the sprayed drug. By precisely regulating the gap value, the mist pesticide can be released in the expected form, concentrated in the target area, and thus achieve the ideal utilization rate of the pesticide while reducing the undesired overflow.

[0036] For example, a layer of fairing 2 components with precise inner diameter and flexible edge characteristics can be fitted around the outside surface of the spray head 1, ensuring that the distance between the two is strictly controlled within 1 mm. Key manufacturing processes include using mold injection molding to produce parts with high-precision fitting sizes, and using micro-clamps or similar fastening elements to adjust the position of the two components and lock them in place during the final assembly stage, so that the precise requirements of fine-scale can be followed while ensuring the convenience of installation.

[0037] In an embodiment, as shown in Figure 3 The outlet end of the fairing 2 of the convenient-to-use pesticide sprayer for rice cultivation is provided with a folded edge 6. This edge effectively blocks the external airflow from entering the inside of the fairing 2, further reducing the impact of wind on the liquid. The folded design of the edge forms a barrier outside the spray head 1, enhancing the stability of the pesticide spraying process.

[0038] The shroud 2 is mounted on the outside of the spray head 1 and tightly fits therewith, and there is no obvious gap between the two, ensuring that air is difficult to enter the inside through the gap to interfere with the liquid flow path. This compact structure not only effectively prevents direct interference from the wind, but also to some extent optimizes the directional flow performance of the liquid after atomization. The outwardly folded edge 6 as part of the end of the shroud 2 can be made by one-time molding process during manufacturing to ensure stable shape and ensure that its shape is not deformed and loose through the rigidity of the material itself. Specifically, the edge is integrally constructed with the shroud 2 and always plays a barrier role during use.

[0039] For example, the shroud 2 and its edge part can be made of a high polymer composite material with high impact resistance and flexibility. During molding, the edge is designed to have a progressive outward expansion structure, so that the entire edge does not break or bend when subjected to a certain pressure or slightly external force collision, maintaining its barrier effect. Such material properties and design scheme can ensure that even in complex and variable working environments, the influence of external natural conditions on pesticide spraying operations can be effectively resisted.

[0040] In one embodiment, the shroud 2 of the pesticide sprayer for rice cultivation and planting according to the present application is made of high-strength stainless steel. As a kind of alloy material with strong corrosion resistance and excellent mechanical properties, stainless steel, after special surface treatment, significantly enhances the wear resistance and corrosion resistance. This ensures that the shroud 2 can maintain stable structure and good working performance in a long-time and high-frequency operating environment, prolongs the service life and ensures the working efficiency.

[0041] Specifically, the shroud 2 is mounted on the outside of the spray head 1 and tightly fits therewith. There is no obvious gap between the shroud 2 and the spray head 1, ensuring that the liquid does not disperse when sprayed due to wind. The high-strength stainless steel shroud 2 not only provides the necessary physical protection to prevent the spray head 1 from being damaged by the external environment, but also avoids the rust problem that may occur in ordinary metals in material selection, ensuring that the performance of the device is not affected after long-term use.

[0042] For example, the shroud 2 can be fixed on the spray head 1 by welding or threaded connection. In order to ensure the sealing, a sealing element such as a rubber gasket can be added to the combined part of the two. In this way, not only a high-strength connection is achieved, but also a good sealing effect is achieved, thereby ensuring the stability and efficiency of the pesticide spraying operation.

[0043] In one embodiment, as Figure 2As shown, the spray head 1 of the pesticide sprayer for rice cultivation and planting according to the present application is internally provided with a set of turbine-type rotating blades 7. The blades are installed inside the spray head 1 near the outlet of the pesticide liquid. The material of the blades is high-strength alloy material, which has good mechanical strength and corrosion resistance, and can ensure long-term stable operation in the agricultural environment. In addition, the surface of the blades has undergone special oxidation-resistant treatment to enhance their durability. The turbine-type rotating blades 7 are designed to automatically rotate at high speed when the pesticide liquid passes through, which further improves the atomization effect of the pesticide liquid and makes the sprayed pesticide liquid particles more uniform and fine.

[0044] Specifically, when the pesticide liquid enters the spray head 1, it hits and drives the blades 7 to rotate under the action of pressure, while generating strong centrifugal force to fully disperse the pesticide liquid into fine droplets for release. In this way, not only is the efficient pesticide spraying coverage area expanded, but also the atomization quality is ensured to be unaffected by environmental changes.

[0045] In one embodiment, continuing to refer to Figure 2 The outlet of the spray head 1 of the pesticide sprayer for rice cultivation and planting according to the present application is provided with a splash-proof net 8, which can further disperse the pesticide liquid and effectively improve the atomization effect of the pesticide liquid during spraying. The design of the splash-proof net 8 can significantly reduce the generation of large particles during atomization and greatly alleviate the impact of external wind on the spraying effect of the pesticide liquid. By installing the splash-proof net 8 inside the spray head 1 closest to the spray opening, it can act on the flow of the pesticide liquid at the last moment before spraying, making it more delicate and uniform.

[0046] Specifically, when the pesticide liquid is pushed by high pressure and passes through the spray head 1, it first comes into contact with the splash-proof net 8. The net is composed of a plurality of tiny through-holes, which are fine and uniform, allowing the liquid to pass through while finely segmenting and initially dispersing it, forming smaller diameter droplets. This not only improves the accuracy and uniformity of the spraying coverage, but also reduces the problem of droplet drift caused by strong winds. More specifically, in the present application, the aperture of the splash-proof net 8 on the outside is larger than that on the inside, because the turbine-type rotating blades 7 generate centrifugal force, causing the flow rate on the outside of the pipe to be larger, thus the aperture of the splash-proof net 8 on the outside is larger than that on the inside, which can produce a more uniform atomization effect.

[0047] For example, the above function can be achieved by constructing a ring or grid structure inside the spray head 1 as the splash-proof net 8. The splash-proof net 8 can be made of stainless steel, plastic or other durable materials, and is ensured to be stably and reliably embedded in the front end opening of the spray head 1. The splash-proof net 8 and the spray head 1 should be kept in close contact to facilitate maintenance and replacement without affecting the overall assembly. In this way, high-efficiency atomization can be ensured while also taking into account structural stability and service life.

[0048] In one embodiment, the inner wall of the pesticide solution pipe 3 of the pesticide sprayer for rice cultivation and planting of the present application is treated with a special anti-seepage coating. The pesticide solution pipe 3, as a key component connecting the spray head 1 and the pesticide tank 4, plays an important role in transporting pesticides. In traditional designs, due to the adhesion of the pesticide liquid or the erosion of some components on the surface of ordinary materials, it may cause liquid leakage or residual adhesion inside the pipe, which affects the subsequent work efficiency and equipment maintenance efficiency. By coating the inner wall of the pesticide solution pipe 3 with a material with anti-seepage and non-stick properties, the above situation can be effectively prevented, thereby ensuring that the pesticide can reach the spray end without loss.

[0049] This treatment method is not only suitable for the application of various conventional pesticide formulations, but also maintains good transmission effect in complex agricultural operation environment. For example, in rainy seasons or humid areas, pesticide spraying is frequent and the amount is large, and the optimized liquid pipeline is not easy to be damaged, deformed or corroded even if it is immersed in a humid environment for a long time, further ensuring the reliability and durability of the system. In addition, the use of such technology can also reduce the cleaning and maintenance cost, and prolong the service life of the entire device.

[0050] Specifically, a composite coating with anti-seepage and non-stick properties can be uniformly applied to the surface of the pipe material through physical vapor deposition or electrostatic spraying process. In this way, not only can the micro gaps be closed microscopically, but also a stable and continuous functional barrier can be built without increasing the fluid motion resistance too high on a macro scale. In addition, for places that need to be frequently disassembled, repaired and inspected, compatible and easy-to-operate materials should also be selected.

[0051] In one embodiment, referring back to Figure 1 The pesticide tank 4 of the pesticide sprayer for rice cultivation and planting of the present application is provided with a detachable liquid inlet 9 at the top. The liquid inlet 9 is tightly fitted with the top of the pesticide tank 4 and has a sealing cover to ensure that the user can operate more conveniently when adding and replacing the pesticide solution, and to ensure that the pesticide tank 4 still maintains strict sealing after operation, effectively preventing the leakage of the pesticide solution during storage and transportation. This structural feature not only improves the user's convenience, but also effectively avoids the environmental pollution risk caused by pesticide leakage.

[0052] The medicine box 4 is one of the main components of the sprayer, responsible for storing and transporting the liquid medicine and ensuring its stability. The design of the liquid filling port 9 takes into account the safety and practicality of operation. The sealing cover and the liquid filling port 9 are connected by threads, which can be firmly closed without affecting the sealing effect. At the same time, the liquid filling port 9 adopts a large-diameter design, which facilitates the quick and accurate completion of the filling work by the filling equipment, further improving the working efficiency of the pesticide sprayer. In addition, the design of this liquid filling structure is also applicable to other related fields of liquid storage and transportation tools.

[0053] Specifically, for example, by applying materials with high chemical resistance to the manufacturing process of the sealing cover and the liquid filling port 9 itself, the assembly can ensure sufficient mechanical strength and chemical stability. At the same time, in actual installation, the sealing performance can be improved by filling the contact gap between the two with a sealing ring or gasket to ensure that there is no liquid leakage during the entire use process. In addition, a locking mechanism can also be provided for the sealing cover to avoid accidental opening due to collisions and other reasons during pesticide spraying, thereby ensuring a safe and reliable operation experience.

[0054] In one embodiment, the medicine liquid pipe 3 of the pesticide sprayer for rice cultivation of the present application is 10% to 20% smaller in diameter than the inlet diameter of the flow guide cover 2. By optimizing the diameter ratio of the medicine liquid pipe 3 and the flow guide cover 2, the smooth flow of the liquid medicine is ensured, the resistance in the pipe is reduced, and the efficiency of the liquid medicine spraying is improved. This design makes full use of the structural advantages of the two, further ensuring the uniformity and efficiency during the medicine spraying process. Specifically, this diameter difference not only prevents the phenomenon of turbulent flow of the liquid medicine in the pipe, reduces unnecessary energy loss, but also reduces the possibility of liquid stagnation while ensuring sufficient flow.

[0055] For example, the inner diameter of the medicine liquid pipe 3 can be set to 8 mm, and the inlet of the flow guide cover 2 is correspondingly set to 10 mm to 11 mm. The close fit and moderate gap between the two make the liquid transmission more smooth, while the flow guide cover 2 can still effectively guide the direction of the liquid medicine and prevent overflow. In the entire system, the liquid medicine flows from the medicine box 4 to the spray head 1 through the adjusted medicine liquid pipe 3, and is concentrated and directed to the spray area by the flow guide cover 2. This optimized design is suitable for various agricultural conditions, especially in application scenarios with high flow requirements.

[0056] In one embodiment, the spray head 1 of the pesticide sprayer for rice cultivation is provided with a section of hose 10 at the liquid inlet. This section of hose 10 can absorb and buffer the impact force of the pesticide liquid during transmission, ensuring that the pesticide liquid is sprayed in a more stable state. This section of hose 10 not only improves the uniformity of pesticide liquid spraying, but also effectively reduces the adverse effects of external wind by reducing turbulence, allowing the pesticide liquid to be sprayed more accurately in the designated area. The selection of the hose 10 should meet the basic requirements of flexibility and corrosion resistance, while maintaining appropriate elasticity and toughness to better achieve the effect of shock absorption and buffering.

[0057] In addition, by providing the hose 10, the spray head 1 can be more flexible during installation and can be adjusted in angle and orientation as needed in different environments or operations. Specifically, the section of hose 10 is directly connected between the pesticide liquid pipe 3 and the spray head 1, without affecting the flow of pesticide liquid, and using its soft properties to adapt to slight positional deviation and vibration, maintaining stable flow of pesticide liquid while ensuring the overall operation convenience of the device.

[0058] In actual technical implementation, in order to ensure the function of the hose 10, materials with excellent chemical stability and flexibility, such as high-quality silicone or polyurethane materials, need to be selected. These materials can withstand the erosion test caused by long-term contact with various pesticides, and also provide sufficient flexibility to support the required functional properties. During manufacturing, the material is securely and firmly connected to the outlet of the pesticide liquid pipe 3 by heat melting or other fixing methods, and the other end is tightly connected to the internal inlet of the spray head 1, thereby ensuring good sealing performance and reliable and stable connection of the entire system.

[0059] In actual operation, when the device is in use, spraying operation can be started by opening the spray head 1. The pesticide liquid is transported from the pesticide tank 4 to the spray head 1 through the pesticide liquid pipe 3, and the spray head 1 atomizes the pesticide liquid into fine particles and sprays it uniformly. At this time, the flow guide cover 2 is arranged outside the spray head 1 to guide and concentrate the sprayed pesticide liquid, effectively reducing the influence of wind on the spraying direction and range. This design ensures that the pesticide liquid is concentrated in the predetermined area, avoiding the scattering of pesticide liquid by wind, thereby reducing pesticide waste and secondary environmental pollution. At the same time, the pesticide tank 4 is fixed on the support 5, which not only provides support and stability, but also facilitates the user to carry the entire sprayer for mobile operation. Through such configuration, the device can achieve efficient and environmentally friendly pesticide spraying operation in the process of rice cultivation.
