Description

Technical Field

[0001] This invention relates to the field of aerosol irrigation nozzle technology, specifically to an aerosol irrigation nozzle device with precisely adjustable particle size. Background Technology

[0002] Aeroponics is a novel soilless cultivation technology that suspends plant roots inside a cultivation container and sprays nutrient solution directly onto the root surface using a spraying device. The irrigation nozzle device is the core component for nutrient solution atomization; its composition and workflow directly affect the atomization effect, root absorption efficiency, and system stability. The complete aeroponics irrigation process can be divided into several steps: first, nutrient solution is prepared as needed and injected into a storage tank; second, a water pump pressurizes the nutrient solution in the storage tank and delivers it to the nozzles via the main pipeline; third, the nutrient solution is sprayed and broken into droplets under pressure, evenly sprayed around the roots; fourth, droplets not absorbed by the roots condense into liquid droplets and return to the storage tank through a return trough for circulation; finally, the nozzles require system maintenance, with weekly disassembly of the nozzles and filters to flush out blockages with clean water to prevent a decrease in atomization efficiency.

[0003] Traditional aeroponic irrigation nozzles suffer from several drawbacks. If the nutrient solution contains undissolved solid particles (such as fertilizer residue or microbial flocs), or if mineral deposits form scale over time, the scale gradually reduces the pipe diameter, decreases water flow, and can even clog nozzle orifices. This leads to decreased or uneven atomization, and the scale provides a habitat for microorganisms, affecting the hygiene of the nutrient solution and potentially causing plant diseases. Furthermore, the atomization particle size of traditional nozzles is primarily determined by the orifice size and water pressure, and cannot be dynamically adjusted after installation. When the particle size is too small, the droplets easily evaporate into water vapor, making it difficult to adhere effectively to the root surface, resulting in insufficient water absorption, especially exacerbated by high temperatures. When the particle size is too large, the strong droplet impact can damage young roots or cause water accumulation on the root surface, increasing the risk of oxygen deficiency. Large droplets also tend to deposit around the roots, causing localized imbalances in nutrient solution concentration. Traditional nozzles cannot switch atomization modes for different growth stages (e.g., fine mist during seedling stage, coarse mist during growth stage), leading to resource waste or growth obstacles.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing aerosol irrigation nozzle devices with precisely adjustable particle size. Summary of the Invention

[0005] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different approach. Specifically, the invention aims to provide an aeroponic irrigation nozzle device with precisely adjustable particle size. This addresses the issues raised in the background section, such as undissolved solid particles in the nutrient solution and long-term deposited mineral scale clogging the nozzle orifice, leading to reduced and uneven atomization volume. Furthermore, the atomized particle size is determined by a fixed orifice diameter and water pressure, making dynamic adjustment impossible. Additionally, the inability to switch atomization modes for different crop growth stages results in resource waste or growth obstacles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an aerosol irrigation nozzle device with precisely adjustable particle size, comprising a device body, the device body being composed of a conical ring and a circular ring, a connecting ring being fitted around the device body, a pressing ring being slidably connected inside the connecting ring, and a cavity being opened inside the connecting ring to cooperate with the sliding of the pressing ring, multiple pressing components being arranged at equal angles on the outer wall of the pressing ring, a rotating component being arranged on one side of the pressing component, a rotating ring being arranged on the top of the rotating component, multiple wall scraping wires being arranged at equal angles on the top of the rotating ring, a fixing ring being fixed to the top of the wall scraping wires, and the fixing ring being fixedly connected to the inner wall of the circular ring of the device body, an adjusting component being arranged on one side inside the conical ring of the device body, and a guide plate being arranged on one side of the conical ring of the device body, the guide plate being an arc-shaped plate.

[0007] Preferably, the pressing assembly includes a fixing block disposed at equal angles on the outer wall of the pressing ring, a fixing shaft is fixed inside the fixing block, an elastic sheet is sleeved on the outer wall of the fixing shaft, and a locking member is fixed on both sides of the elastic sheet.

[0008] Preferably, the connecting ring has a cavity for moving with the fixing block, and the connecting ring has a locking groove for engaging the engaging component inside.

[0009] Preferably, the rotating assembly includes a squeezing block fixed to the bottom end of the pressing ring, a rubber pad is provided at the bottom of the squeezing block and the rubber pad is circular, a push block is provided at equal angles on the inner wall of the rubber pad, a push rod is slidably connected to the top of the push block, and an inclined groove is provided at the bottom end of the rotating ring to cooperate with the push rod.

[0010] Preferably, the connecting ring has a cavity for placing a rubber pad, and the main body of the device has a cavity for sliding with the push block.

[0011] Preferably, a spring is provided inside the cavity of the main body of the device, with one end of the spring fixed to the inner wall of the cavity and the other end of the spring fixed to one side of the push block.

[0012] Preferably, the adjustment component includes a connecting rod that is equidistantly positioned at the top of the rotating ring, a rotating component that is fixed to the top of the connecting rod, a fixing plate that is disposed inside the rotating component, and a cavity for placing the rotating component and the fixing plate that is opened inside the conical ring of the main body of the device, and the fixing plate is fixedly connected to the inner wall of the cavity.

[0013] Preferably, the rotating component has sliding grooves at equal angles, and a fixed column is provided in the sliding groove.

[0014] Preferably, a sliding block is fixed at the bottom of the fixed column, and a limiting groove is provided at the top of the fixed plate to cooperate with the sliding block to slide.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The pressing ring drives the rotating ring to rotate, which in turn drives the rotating component to rotate via the connecting rod. The rotating component rotates and drives the fixed column to slide via the sliding groove. The sliding of the fixed column causes the sliding block to slide within the limiting groove opened in the fixed plate, thereby adjusting the size of the nozzle orifice. Stopping the pressing of the rotating ring fixes the size of the orifice. This allows the nozzle orifice size to be adjusted according to the growth cycle or type of different crops, thus preventing the reduction or unevenness of atomization and plant diseases.

[0017] 2. The pressing ring drives the squeezing block to squeeze the rubber pad. After the rubber pad is squeezed by external force, it drives the push block to move. The push block moves and pushes the push rod upward through the inclined surface at its top. The push rod moves upward and drives the rotating ring to rotate through the inclined groove at the bottom of the rotating ring. In turn, it drives the scraper wire to rotate. The shearing force generated by the rotation of the scraper wire removes the deposits on the inner wall of the nozzle, preventing the deposits from gradually reducing the inner diameter of the pipe, reducing the water flow speed, or even clogging the nozzle hole.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 9 This invention provides a technical solution: an aerosol irrigation nozzle device with precisely adjustable particle size, comprising a device body 1, which is composed of a conical ring and a circular ring. A connecting ring 2 is fitted over the device body 1, and a pressing ring 3 is slidably connected inside the connecting ring 2. The connecting ring 2 has a cavity that slides with the pressing ring 3. Multiple pressing components are arranged at equal angles on the outer wall of the pressing ring 3. A rotating component is arranged on one side of the pressing component. A rotating ring 6 is arranged on the top of the rotating component. Multiple scraping wires 7 are arranged at equal angles on the top of the rotating ring 6. A fixing ring 8 is fixed to the top of the scraping wires 7, and the fixing ring 8 is fixedly connected to the inner wall of the circular ring of the device body 1. An adjusting component is arranged on one side of the conical ring of the device body 1, and a guide plate 10 is arranged on one side of the conical ring of the device body 1. The guide plate 10 is an arc-shaped plate.

[0030] In practice, when the pressing ring 3 moves down inside the connecting ring 2, on the one hand, the pressing component drives the rotating ring 6 to rotate, which in turn drives the scraping wire 7 to clean the inner wall of the device body 1. On the other hand, the adjusting component changes the size of the inner hole of the conical ring, thereby achieving precise adjustment of the atomized particle size. The fixing ring 8 provides support and reaction force for the scraping wire 7, and the arc-shaped guide plate 10 guides the liquid to form turbulence to enhance the atomization effect. The entire mechanism can simultaneously complete the hole adjustment and self-cleaning functions with a single pressing action.

[0031] As a further embodiment of the present invention, the pressing component includes a fixing block 401 that is equally angled on the outer wall of the pressing ring 3, a fixing shaft 402 is fixed inside the fixing block 401, an elastic sheet 403 is sleeved on the outer wall of the fixing shaft 402, and a locking member 404 is fixed on both sides of the elastic sheet 403.

[0032] In practice, when the pressing ring 3 is pressed down, the fixing block 401 moves accordingly, causing the fixing shaft 402 and the elastic plate 403 to move down synchronously; the engaging parts 404 on both sides of the elastic plate 403 engage elastically with the engaging groove 405 on the inner wall of the connecting ring 2 during the movement, and the elastic plate 403 achieves step-by-step positioning through deformation, thereby converting the pressing action into precise mechanical displacement transmission.

[0033] As a further embodiment of the present invention, the connecting ring 2 has a cavity that moves with the fixing block 401, and the connecting ring 2 has a locking groove 405 that engages with the locking member 404.

[0034] In practice, when the pressing ring 3 is pressed down, the fixing block 401 moves in the cavity of the connecting ring 2, and at the same time drives the locking member 404 to slide along the locking groove 405. The specific structure of the locking groove 405 enables the locking member 404 to engage elastically, thereby achieving step-by-step positioning and mechanical self-locking of the pressing ring 3, ensuring the accuracy and stability of the adjustment process.

[0035] As a further embodiment of the present invention, the rotating assembly includes a pressing block 501 fixed to the bottom end of the pressing ring 3. A rubber pad 502 is provided at the bottom of the pressing block 501, and the rubber pad 502 is circular. A push block 503 is provided at equal angles on the inner wall of the rubber pad 502. A push rod 505 is slidably connected to the top end of the push block 503. A groove 506 that cooperates with the push rod 505 is provided at the bottom end of the rotating ring 6.

[0036] In practice, when the pressing ring 3 is pressed down, the squeezing block 501 compresses the annular rubber pad 502, causing it to expand radially and push the push block 503 to move. The push block 503 drives the push rod 505 to slide along the inclined groove 506 at the bottom of the rotating ring 6, converting the vertical pressure into the rotational motion of the rotating ring 6, thereby realizing mechanical transmission and function switching.

[0037] As a further embodiment of the present invention, the connecting ring 2 has a cavity for placing the rubber pad 502, and the main body 1 of the device has a cavity for sliding with the push block 503.

[0038] In practice, when the pressing ring 3 is pressed down, the squeezing block 501 presses the rubber pad 502 into the dedicated cavity of the connecting ring 2, causing it to expand radially. The expanded rubber pad 502 pushes the push block 503 to slide in the cavity of the main body 1 of the device, thereby converting the vertical pressure into horizontal displacement, realizing the transmission of mechanical energy and functional conversion. This compact design ensures the reliability and stability of the action transmission through elastic deformation and precise cavity fit.

[0039] As a further embodiment of the present invention, a spring 504 is provided in the cavity of the main body 1 of the device. One end of the spring 504 is fixed to the inner wall of the cavity, and the other end of the spring 504 is fixed to one side of the push block 503.

[0040] In practice, when the pressing ring 3 is pressed down, the push block 503 compresses the spring 504 to store energy. After the pressing ring 3 is released, the spring 504 releases its elastic force to push the push block 503 to reset, thereby restoring the entire mechanism to its initial state. This spring 504 reset design realizes the automatic return function of the device through the storage and release of elastic potential energy, ensuring reliable reset after each adjustment.

[0041] As a further embodiment of the present invention, the adjustment component includes a connecting rod 901 set at the top of the rotating ring 6 at equal angles, a rotating component 902 fixed at the top of the connecting rod 901, a fixing plate 906 provided inside the rotating component 902, and a cavity for placing the rotating component 902 and the fixing plate 906 opened inside the conical ring of the device body 1, and the fixing plate 906 is fixedly connected to the inner wall of the cavity.

[0042] In practice, when the rotating ring 6 rotates, it drives the connecting rod 901 to rotate synchronously, which in turn drives the rotating part 902 to rotate in the conical ring cavity of the main body 1 of the device. Since the fixed plate 906 is fixedly connected to the inner wall of the cavity, the rotational motion of the rotating part 902 will be converted into the linear displacement of the sliding block 905 through its internal mechanism, thereby achieving precise adjustment of the nozzle orifice diameter. This design converts the rotational motion into the adjustment action through mechanical linkage, ensuring the stability and accuracy of the adjustment process.

[0043] As a further embodiment of the present invention, the rotating member 902 is provided with a sliding groove 903 at equal angles, and a fixing post 904 is provided in the sliding groove 903.

[0044] In practice, when the rotating part 902 rotates, the sliding groove 903 with equal angles will generate relative motion with the fixed column 904. The fixed column 904 is guided to generate precise displacement through the specific trajectory of the sliding groove 903, thereby converting the rotational motion into controllable linear motion or specific trajectory motion, and realizing precise control of mechanical transmission.

[0045] As a further embodiment of the present invention, a sliding block 905 is fixed at the bottom of the fixed column 904, and a limiting groove 907 is provided at the top of the fixed plate 906 to cooperate with the sliding block 905 to slide.

[0046] In practice, when the fixed column 904 moves within the sliding groove 903 as the rotating component 902 rotates, it will simultaneously drive the sliding block 905 to slide within the limiting groove 907 of the fixed plate 906. The specific trajectory of the limiting groove 907 constrains the movement path of the sliding block 905, converting the rotational motion of the rotating component 902 into a controlled linear displacement, thereby achieving precise mechanical transmission and position adjustment functions.

[0047] Working principle: When using this aerosol irrigation nozzle device with adjustable particle size, firstly, the nutrient solution is prepared as needed and injected into the storage tank. Then, the water pump is turned on and the pressure is adjusted to the optimal working range of the nozzle. The water pump pressurizes the nutrient solution in the storage tank, so that the nutrient solution is transported from the main pipeline to the filter, and then from the branch pipe to the nozzle. When the high-pressure liquid passes through the guide vane 10 set inside the nozzle, the liquid passes through the narrow nozzle at high speed and generates turbulence by violently rubbing against the nozzle wall. The liquid is torn into fine liquid filaments, and the liquid filaments are further broken into droplets.

[0048] Before starting the water pump, the required particle size of the nozzle is determined according to the type and growth status of the plant. The pressing ring 3 is manually pressed to make it slide inside the connecting ring 2. The movement of the pressing ring 3 causes multiple fixing blocks 401 set at equal angles on its outer wall to move down synchronously. The downward movement of the fixing blocks 401 causes the locking part 404 to move down through the fixing shaft 402. When the locking part 404 moves down, it is fixed step by step through the locking groove 405 opened in the connecting ring 2. When the locking part 404 moves from the cavity in the locking groove 405 to the next cavity, it is driven by the elastic plate 403 to move into the fixing block 401. When it reaches the next cavity, the elastic plate 403 drives the locking part 404 to engage with the locking groove 405, thereby fixing the position of the pressing ring 3.

[0049] When the pressing ring 3 moves, it drives the pressing block 501 fixed at its bottom to move down synchronously. The pressing block 501 moves down and presses the rubber pad 502 at its bottom. After being pressed by external force, the rubber pad 502 expands into the cavity opened in the main body 1 of the device, thereby pushing the push block 503 in the cavity. The push block 503 moves and pushes the push rod 505 up through the inclined surface opened at its top. The push rod 505 moves up and drives the rotating ring 6 to rotate through the inclined groove 506 opened at the bottom of the rotating ring 6 (the rotating ring 6 and the main body 1 of the device are connected by a limit rotation). The rotation of the rotating ring 6 drives the scraping wire 7 fixedly connected at its top to rotate. The scraping wire 7 is in contact with the inner wall of the main body 1 of the device, and it is fixedly connected to the main body 1 of the device at one end through the fixing ring 8, thereby removing the deposits on the inner wall of the nozzle and preventing the atomization volume of the aeroponic irrigation nozzle device from decreasing or becoming uneven.

[0050] When the pressing ring 3 drives the rotating ring 6 to rotate, the connecting rod 901 fixedly connected to its top drives the rotating part 902 to rotate. The rotation of the rotating part 902 drives the sliding groove 903 to rotate synchronously, so that the fixed column 904 slides in the sliding groove 903. When the fixed column 904 slides, it drives the sliding block 905 to slide in the limiting groove 907 opened in the fixed plate 906. Then, by adjusting the rotation angle of the rotating part 902, the distance of movement of multiple sliding blocks 905 is adjusted, thereby adjusting the size of the nozzle orifice. When the nozzle orifice is adjusted, the pressing of the rotating ring 6 is stopped, and when the rotating ring 6 rotates, it drives the scraping wire 7 to remove scale. This realizes that whenever the nozzle orifice is adjusted, the inside of the nozzle is simultaneously descaled (by manually pulling the pressing ring 3 to contact the rubber pad 502, the spring 504 resets the push block 503, and the push rod 505 moves down to make the rotating ring 6 reverse, thereby driving the sliding block 905 to reset).

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
