Description

Technical Field

[0001] This invention relates to the field of humidifiers, and more particularly to a centrifugal ultrasonic humidifier. Background Technology

[0002] Centrifugal ultrasonic humidifiers are air humidification devices that combine ultrasonic and centrifugal technologies. They first atomize water into tiny particles through high-frequency ultrasonic vibrations, then spray these atomized water particles outwards as a high-velocity atomized airflow through a high-speed rotating centrifugal disc, thus regulating air humidity. They offer advantages such as excellent atomization and a wide spray range, making them particularly advantageous in livestock farming and greenhouse cultivation. Adding disinfectant to the water allows the disinfectant to be sprayed outwards as atomized airflow, resulting in outstanding performance in humidity regulation, cooling, energy saving, and disease control. However, when using centrifugal ultrasonic humidifiers for long-distance, large-area disinfection and humidification, a large amount of atomized airflow is sprayed into the air in a short time. The water droplets in this atomized airflow do not have time to vaporize in the air before dripping onto the ground, leading to high ground humidity, which is detrimental to ground environmental humidity management in livestock farming. Summary of the Invention

[0013] As an improvement to the above scheme, the flow guiding channel structure of the flow guiding block is designed to be inclined upward towards the inner wall of the spray nozzle.

[0029] Example 1: A centrifugal ultrasonic humidifier of this example, such as... Figures 1-7 As shown, the device includes a housing 1, casters 11, a cover plate 12, a liquid inlet pipe 13, a drain pipe 14, an air inlet pipe 2, an ultrasonic atomizer 3, a centrifugal sprayer 4, a mist delivery pipe 41, a mounting bracket 51, an outer spray nozzle 52, a middle spray nozzle 53, an inner spray nozzle 54, a blower 6, a telescopic plate 71, a connecting block 72, a locking assembly, and a baffle 76. The housing 1 is equipped with four casters 11. The cover plate 12 is also installed on the housing 1. The cover plate 12 has an air inlet pipe 2. Furthermore, the air intake pipe 2 is equipped with a filter screen structure, which intercepts foreign objects flowing through the air intake channel; an ultrasonic atomizer 3 is installed inside the housing 1, and the air intake port of the ultrasonic atomizer 3 is connected to the air intake pipe 2; the housing 1 is equipped with an inlet pipe 13 connected to the liquid inlet port of the ultrasonic atomizer 3; a centrifugal sprayer 4 is installed inside the housing 1, and the air intake port of the centrifugal sprayer 4 is connected to the air outlet port of the ultrasonic atomizer 3; the housing 1 is equipped with an inlet pipe 13 connected to the liquid outlet port of the centrifugal sprayer 4. The drain pipe 14 of the drain port of the mist machine 4; a fixed bracket 51 is connected to the cover plate 12; an outer spray cylinder 52 is slidably connected inside the fixed bracket 51; a middle spray cylinder 53 is slidably connected inside the outer spray cylinder 52; an inner spray cylinder 54 is slidably connected inside the middle spray cylinder 53; the outer spray cylinder 52, the middle spray cylinder 53 and the inner spray cylinder 54 together form a telescopic spray cylinder assembly; a mist delivery pipe 41 is connected between the air outlet port of the centrifugal sprayer 4 and the air inlet port of the inner spray cylinder 54; an upward-facing... A blower 6 delivers atomized airflow; four telescopic plates 71 are rotatably connected to the upper port of the inner spray cylinder 54 via a rotating shaft, and a notch structure 710 is provided between each pair of adjacent telescopic plates 71; a connecting block 72 is rotatably connected to all the telescopic plates 71 via a rotating shaft; two quick-release locking components are connected to the connecting block 72 and fixed to the inner spray cylinder 54; a baffle 76 is fixed to the connecting block 72, and the edge of the baffle 76 is set as an upward folded inclined structure.

[0030] like Figure 3 As shown, in this embodiment, the fixing frame 51 is rotatably connected to the cover plate 12; a gear ring 55 is fixedly connected to the fixing frame 51; a bidirectional motor 56 is installed on the cover plate 12; a gear 57 is fixedly connected to the output shaft of the bidirectional motor 56; the gear 57 meshes with the gear ring 55.

[0031] like Figure 6 and Figure 7 As shown, the locking assembly of this embodiment includes a slider 73, a compression spring 74, and a plug rod 75. The slider 73 is slidably connected to the connecting block 72. The compression spring 74 is fixedly connected to both the slider 73 and the connecting block 72. The plug rod 75 is fixedly connected to the slider 73. The inner wall of the inner spray cylinder 54 is provided with a plurality of insertion hole structures 5401, and the plug rod 75 is inserted into one of the insertion hole structures 5401 corresponding to the initial position of the slider 73.

[0032] The steps for using a centrifugal ultrasonic humidifier in greenhouse cultivation according to this embodiment are as follows.

[0033] First, the staff moves the casing 1 to the central area of ​​the planting greenhouse using the casters 11. The inlet pipe 13 and the drain pipe 14 are connected to the external liquid delivery equipment and waste liquid collector, respectively. The external liquid delivery equipment continuously delivers water to the ultrasonic atomizer 3 through the inlet pipe 13. The ultrasonic atomizer 3 continuously draws in outside air through the air intake pipe 2 and atomizes the water into tiny particles. Then, the centrifugal sprayer 4 delivers the atomized tiny water particles in a high-speed atomized airflow state along the mist delivery pipe 41 into the inner spray cylinder 54. At the same time, the blower 6 blows the atomized airflow upward in the inner spray cylinder 54, allowing the atomized airflow to continuously spray upward along the inner spray cylinder 54. The wastewater generated during the operation of the centrifugal sprayer 4 is discharged into the waste liquid collector through the drain pipe 14.

[0034] During this period, the telescopic spray nozzle assembly, consisting of the outer spray nozzle 52, the middle spray nozzle 53, and the inner spray nozzle 54, is in a state as follows: Figure 1 The downward retracted position shown allows the outlet end of the inner spray nozzle 54 to spray the atomized airflow outward at a distance closer to the ground, thereby reducing the residence time of the atomized airflow in the air. This ensures that the atomized airflow drips onto the plant surface and soil as droplets before it has a chance to vaporize, effectively increasing soil surface humidity. Figure 4As shown, four telescopic plates 71 form notch structures 710 in four directions. As the atomized airflow is ejected outward through the four notch structures 710 at the outlet end of the inner spray cylinder 54, the atomized airflow is also guided upward by the inclined structure of the baffle 76, which causes the atomized airflow ejected from the four notch structures 710 to be sprayed in four directions along the inclined structure of the baffle 76, thus expanding the spray range of the atomized airflow in the area closer to the ground. At the same time, the bidirectional motor 56 drives the gear 57 to rotate back and forth in the forward and reverse directions. Meanwhile, the gear 57 meshes with the gear ring 55 to drive the telescopic spray cylinder assembly in the fixed frame 51 to rotate back and forth in the forward and reverse directions. By continuously changing the spray direction of the atomized airflow, the atomized airflow can be evenly covered in all directions within the spray range.

[0035] The steps for using a centrifugal ultrasonic humidifier in livestock farming according to this embodiment are as follows.

[0036] First, the staff moves the casing 1 to the central area of ​​the livestock farm using the casters 11. The inlet pipe 13 and the drain pipe 14 are connected to the external inlet conveying equipment and waste liquid collector, respectively. The external inlet conveying equipment continuously delivers water and disinfectant of any proportion to the ultrasonic atomizer 3 through the inlet pipe 13. The ultrasonic atomizer 3 continuously draws in outside air through the air inlet pipe 2. The ultrasonic atomizer 3 atomizes the water and disinfectant into tiny particles. Then, the centrifugal sprayer 4 delivers the atomized tiny water particles in a high-velocity atomized airflow along the mist delivery pipe 41 into the inner spray cylinder 54. At the same time, the blower 6 blows the atomized airflow upwards in the inner spray cylinder 54, allowing the atomized airflow to continuously spray upwards along the inner spray cylinder 54. The wastewater generated during the operation of the centrifugal sprayer 4 is discharged into the waste liquid collector through the drain pipe 14.

[0037] During this period, the staff will pull out the telescopic spray nozzle assembly, which consists of the outer spray nozzle 52, the middle spray nozzle 53, and the inner spray nozzle 54, to the desired position. Figure 9 The upward extension shown allows the outlet end of the inner spray nozzle 54 to spray the atomized airflow outward at a greater distance from the ground, thereby prolonging the residence time of the atomized airflow in the air. This allows the atomized airflow more time to vaporize and diffuse in the air, reducing the amount of atomized airflow dripping onto the ground of the breeding area in the form of droplets. This avoids the impact of excessive humidity on the ground humidity environment of the breeding area. The worker uses two fingers to slide the two sliders 73 separately. Pulling the two sliders 73 causes the compression spring 74 to compress towards the sliders 73, while the sliders 73 drive the insertion rod 75 to move away from the insertion hole structure 5401. The worker then pushes the sliders 73 downward, causing the connecting block 72 to move downward. At the same time, the connecting block 72 causes the telescopic plate 71 to flip downward. Figure 10In the indicated state, after the operator releases the slider 73, the compressed spring 74 pushes the slider 73 to drive the insertion rod 75 into the corresponding insertion hole structure 5401, keeping the connecting block 72 at its current height inside the inner spray cylinder 54. At this time, the notch structure 710 formed between the four telescopic plates 71 in four directions increases, increasing the flow rate of the atomized airflow sprayed outward from the outlet end of the inner spray cylinder 54. After the atomized airflow flows upward along the notch structure 710, it will continue to spray upward along the baffle 76 and the inner wall of the inner spray cylinder 54, allowing the atomized airflow to spray to a higher distance from the ground, further extending the residence time of the atomized airflow in the air, thereby reducing the phenomenon of atomized airflow dripping onto the ground of the breeding site. After the upward sprayed atomized airflow contacts the roof of the breeding site, the atomized airflow will spread outward along the roof of the breeding site, increasing the coverage area of ​​the atomized airflow, and realizing large-scale space disinfection and humidification treatment within the breeding site.

[0038] When the breeding area is large, the worker uses two fingers to pull the two sliders 73, causing the compression spring 74 to compress towards the sliders 73. At the same time, the sliders 73 move the insertion rod 75 away from the insertion hole structure 5401. The worker then pulls the sliders 73 upwards, causing the connecting block 72 to move upwards. Simultaneously, the connecting block 72 causes the telescopic plate 71 to flip upwards until it reaches the desired position. Figure 11 In the indicated state, after the operator releases the slider 73, the compressed spring 74 pushes the slider 73 to drive the insertion rod 75 into the corresponding insertion hole structure 5401, keeping the connecting block 72 at its current height inside the inner spray cylinder 54. At this time, the notch structures 710 formed in the four directions between the four telescopic plates 71 are also enlarged, increasing the flow rate of the atomized airflow from the outlet end of the inner spray cylinder 54. After the atomized airflow flows upward along the four notch structures 710, the atomized airflow is directly sprayed obliquely upward along the baffle 76 in various directions. Although the atomized airflow from Figure 11 The upward spray height at the outlet end of the inner spray nozzle 54, as shown, is less than that of the atomized airflow from... Figure 10 The internal spray nozzle 54, as shown, sprays upwards from its outlet end, but the atomized airflow... Figure 11 The spray range of the inner nozzle 54 at the outlet end, as shown, in all directions is much greater than that of the atomized airflow from... Figure 10 The inner spray nozzle 54, as shown, sprays in all directions from its outlet end, enabling long-distance, large-area space disinfection and humidification treatment in a large breeding area.

[0039] Example 2, as Figures 1-8As shown, based on Embodiment 1, this embodiment has four hollow structures 5402 on the inner spray cylinder 54; each of the four hollow structures 5402 is connected to an air inlet 81; each of the four air inlet 81 is rotatably connected to a flap 82 that flips outward from the inner spray cylinder 54, and the flap 82 has an air outlet channel structure 8201 connected to the air inlet 81; two torsion springs 83 are fixed between each of the four air inlet 81 and the flap 82; the inner spray cylinder 54 is initially located inside the middle spray cylinder 53, and the flap 82 is blocked by the inner wall of the middle spray cylinder 53 and is in a state of being pressed into the corresponding hollow structure 5402 of the inner spray cylinder 54, the outlet end of the air outlet channel structure 8201 of the flap 82 is blocked by the hollow structure 5402, and the torsion spring 83 is in a torsional state; at the moment when the inner spray cylinder 54 is pulled upward from the middle spray cylinder 53, the flap 82 on the inner spray cylinder 54 loses the air outlet from the middle spray cylinder 53. The obstruction of the spray nozzle 53 causes the torsion spring 83 to quickly push the flap 82 outward, exposing the outlet end of the air outlet channel structure 8201 of the flap 82 to the outside of the inner spray nozzle 54. After the inner spray nozzle 54 is pulled upward, the atomized airflow is sprayed upward along the inner spray nozzle 54 and performs long-distance, large-area space disinfection and humidification treatment. During this process, most of the atomized airflow sprayed from the inner spray nozzle 54 is sprayed to areas far away from the casing 1. Only a small portion of the atomized airflow sprayed from the inner spray nozzle 54 covers areas closer to the casing 1. Therefore, in this embodiment, by using the air inlet 81 and the flap 82 to guide the atomized airflow flowing in the inner spray nozzle 54, some of the atomized airflow is sprayed along the air outlet channel structure 8201 of the air inlet 81 and the flap 82 to areas closer to the casing 1, so that the large-area space disinfection and humidification treatment can be fully covered in all directions.

[0040] In this embodiment, the lower ends of the four flaps 82 are all designed with wedge-shaped arc structures. During the process of retracting the inner spray cylinder 54 downward into the middle spray cylinder 53, when the inner spray cylinder 54 drives the flaps 82 downward past the top of the middle spray cylinder 53, the wedge-shaped arc structure at the lower end of the flaps 82 is squeezed from the top of the middle spray cylinder 53, causing the flaps 82 to be pressed into the corresponding hollow structure 5402. The torsion spring 83 is then in a twisted state, thus completing the retraction of the four flaps 82 in one step without the need for manual retraction of the flaps 82 by the operator.

[0041] Example 3, as Figures 1-8As shown, based on Embodiment 2, this embodiment has a guide block 9 fixedly connected inside the inner spray cylinder 54, located above the blower 6; the edge of the guide block 9 has several vertically penetrating guide channel structures 901; each guide channel structure 901 of the guide block 9 is designed to be inclined upward towards the inner wall of the inner spray cylinder 54; when the blower 6 blows the atomized airflow output from the mist pipe 41 upward, the atomized airflow will flow obliquely upward towards the inner wall of the inner spray cylinder 54 along the guide channel structures 901 along the edge of the guide block 9. Compared with letting the atomized airflow flow directly upward along the various areas inside the inner spray cylinder 54, by controlling the atomized airflow to flow upward along the inner wall of the inner spray cylinder 54 through the guide block 9 of this embodiment, more atomized airflow can enter the air inlet hopper 81, and then more atomized airflow can be sprayed outward into the air at close range along the air outlet channel structure 8201 of the flap 82.

Therefore, the detailed description of the embodiments in this disclosure is for illustrative purposes only and is not intended to limit the invention; rather, the scope of protection is defined by the content of the claims.
