DETAILED DESCRIPTION

[0038] The above description is made in conjunction with the accompanying drawings. Figure 1 to the accompanying drawings. Figure 5 The technical solutions in the embodiments of the present application are clearly and completely described, and obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] In many applications, such as pesticide spraying in agriculture and painting operations in industry, spraying technology can evenly disperse and cover the target surface with liquid in the form of tiny particles. Taking pesticide spraying as an example, traditional irrigation methods cannot guarantee the even distribution of pesticides on crop leaves, stems, and other parts, while spraying technology can ensure that pesticide droplets adhere evenly to all parts of the crop, ensuring comprehensive pest and disease control and reducing the risk of localized pest and disease outbreaks.

[0040] However, in the existing technology, the liquid needs to be converted into atomization through an ultrasonic instrument, which makes the assembly of the spray equipment cumbersome and the operation inconvenient. Furthermore, since the air guide plate is located far from the water outlet, the liquid atomization is incomplete, the atomization is not fine, and the atomization effect is poor.

[0041] In response, the inventors have provided a spray generator, such as... Figure 1 As shown, the airflow direction from left to right on the paper's surface is from inlet to outlet. This spray generator has an air collecting structure 1, a liquid outlet structure 2, and an airflow atomizing device 3. The air collecting structure 1 is used to collect gas. The air collecting structure 1 has a housing 11; the housing 11 has a hollow inner cavity to form the air collecting chamber 12; the housing 11 has a liquid inlet 111; the liquid inlet 111 is connected to the liquid outlet 22 through the liquid outlet structure 2.

[0042] It should be noted that the liquid outlet structure 2 in this embodiment is a water guide pipe 21. The water guide pipe 21 guides water from the outside to the liquid outlet 22 through the liquid inlet 111, so that the liquid outlet 22 can form a water column when in use.

[0043] The air collecting structure 1 also has an air inlet 14 and an air outlet 13. The gas enters from the air inlet 14 on the left and flows out from the air outlet 13. The air collecting structure 1 has an air collecting cavity 12. The air collecting cavity 12 is connected to the interior 121 and the exterior 122 of the air collecting cavity through the air outlet 13. The air collecting cavity 12 has a smooth structure that gradually narrows from left to right. It should be understood that this design is conducive to gathering the gas at the air inlet 14 to the air outlet 13, so that the airflow velocity at the air outlet 13 is greater, which is conducive to the formation of a cyclone.

[0044] Furthermore, such as Figure 2As shown, the air outlet 13 has the airflow atomizing device 3; the airflow atomizing device 3 is used to form a cyclone and process the liquid into an atomized form. The airflow atomizing device 3 covers the air outlet 13 to partially block the air outlet 13. The airflow atomizing device 3 includes a fixed connection or a detachable connection with the edge of the air outlet 13. The fixed connection includes the case where the airflow atomizing device 3 is integrally formed with the end of the air outlet 13, and the detachable connection includes a screw installation connection. In this embodiment, it is preferable that the airflow atomizing device 3 is integrally formed with the end of the air outlet 13. This design can effectively prevent airflow leakage at this point, which would affect the effective formation of the cyclone.

[0045] Detailed, such as Figures 1 to 3 As shown, the airflow atomizing device 3 includes a flow diversion structure 31 and an air guide column 32. The flow diversion structure 31 includes an air duct cover 311 and an air guide component 312. The air duct cover 311 has a baffle 3111 and a side wall 3112. When the air duct cover 311 is closed on the air outlet 13 to house the air guide component 312 inside the air duct cover 311, the side wall 3112 is located on one side of the air guide component 312, and the baffle 3111 is located above the air guide component 312 and partially blocks the air guide component 312. The side wall 3112, the baffle 3111, and the air guide component 312 cooperate to form an airflow channel 33. The airflow channel 33 guides the gas flow along the outer surface of the air guide column 32 to the front end, so as to form an airflow negative pressure zone 34 in the front area near the air guide column 32.

[0046] It should be understood that in this embodiment, when gas enters the air collecting chamber 12 from the air inlet 14, the gas flows along the gradually narrowing direction of the air collecting chamber 12, since the air collecting chamber 12 is shaped to gradually narrow from the air inlet 14 to the air outlet 13. Therefore, as the gas flows from the inside of the air collecting chamber 12 towards the air outlet 13, the gas velocity gradually increases. This is understandable because, for the same gas volume, the smaller the gas flow channel, the faster the gas velocity.

[0047] When gas flows into the vicinity of the air outlet 13, the gas will flow outward along the airflow channel 33. Specifically, as... Figure 3As shown, when the air duct cover 311 is closed over the air outlet 13 to house the air guide 312 inside the air duct cover 311, the side wall 3112 is located on one side of the air guide 312, and the baffle 3111 is located above the air guide 312 and partially blocks it. The side wall 3112, the baffle 3111, and the air guide 312 cooperate to form a narrow channel, which is the airflow channel 33. The gas flows along the predetermined direction of the airflow channel 33 until it collides with the air guide column 32. It should be noted that the air guide plate 313 has the air guide column 32; this design facilitates that when gas hits the air guide column 32, the gas can be guided by the surface of the air guide column 32 to flow to the top of the air guide column 32, and the top of the air guide column 32 has a liquid outlet 22, when the airflow reaches this point, it can cut the liquid coming out of the liquid outlet 22 into a mist.

[0048] like Figure 4 As shown, preferably, the air guide column 32 has a conical structure. The conical structure causes the entire body of the air guide column 32 to gradually narrow from the bottom to the top, which facilitates guiding the airflow from the bottom to the top, allowing the airflow to merge with the water column at the liquid outlet 22, and thus better cutting the liquid into a mist. In another embodiment, the air guide column 32 can also be a cylindrical structure. Similarly, the cylindrical structure also allows the airflow to flow along the surface of the column to the top, thereby cutting the water column into a mist. In summary, the shape of the air guide column 32 is not limited to a conical or cylindrical structure; any structure that facilitates guiding the airflow to the top is within the protection scope of this technical solution.

[0049] To better guide airflow to the outside, in this embodiment, the air guide 312 has a sheet-like structure and a root 3121. The root 3121 is close to the air guide 312 and connected to an air guide base plate 313. Specifically, in this embodiment, the air guide 312 and the air guide base plate 313 are integrally formed. In other embodiments, the air guide 312 is detachably connected to the air guide base plate 313, as long as it is convenient to manufacture and assemble the air guide 312 and the air guide base plate 313.

[0050] The air guide 312 extends outward from its root 3121 until it abuts against the surface of the inner sidewall 3112 of the air duct cover 311. When the air duct cover 311 is closed at the air outlet 13, the end 3123 of the air guide 312 abuts against the sidewall 3112. The upper side of the end 3123 also has a guide pin 3122, which facilitates guiding the air duct cover 311 to close onto the air outlet 13.

[0051] Furthermore, the air guide 312 is perpendicular to the air guide base plate 313. This design allows the gas flowing out of the airflow channel 33 to directly reach the air guide column 32, and under the guidance of the air guide column 32, the airflow can better form an air jet flowing towards the top of the air guide column 32.

[0052] Furthermore, there are several air guides 312; different air guides 312 have an included angle 3124, the included angle 3124 is 60°, and air duct cavities 314 are formed between different air guides 312.

[0053] It should be understood that when the included angle is 60°, the air outlet 13 is divided into six equal parts. These six parts divide the airflow from the air outlet 13 into six sub-airflow streams. When the airflow exits from the air outlet 13, the six sub-airflow streams rush towards the top of the guide column 32, cutting the water column exiting the liquid outlet 22 into a mist from six directions. This design allows for finer cutting of the water column mist particles, resulting in finer atomization and a better atomization effect. In addition, the different guide components 312 form an air-guiding cavity 314, allowing the gas exiting the airflow channel 33 to flow to the outside through the air-guiding cavity 314. Here, the convergence of the airflow is further enhanced, enabling the airflow to better cut and atomize the water column at the liquid outlet 22.

[0054] It should also be noted that the number of the air guides 312 is set according to actual needs. The more air guides 312 there are, the more airflow sub-beams are generated, which can cut the water column into finer pieces, atomize more delicately, and achieve better atomization effect.

[0055] Furthermore, the air guide column 32 connects both sides of the air guide base plate 313. The liquid outlet structure 2 has a liquid outlet 22 for discharging liquid; specifically, the liquid outlet 22 is located at the front end of the air guide column 32 and at the negative pressure zone of the airflow.

[0056] It should be understood that the negative pressure zone of the airflow is the low pressure zone of the airflow. By placing the liquid outlet 22 in this location, the water column can automatically flow out from the liquid outlet 22 under the influence of the airflow difference, effectively solving the problem that the existing technology requires the use of a water pump to extract the water, which is very cumbersome.

[0057] When the spray generator is in use, the airflow atomizing device 3 enables the gas generated from the air collection structure 1 to converge in the airflow negative pressure zone and chordally cut the water column into a mist.

[0058] In addition, such as Figure 5As shown, a sprayer 100 is proposed, including a liquid storage tank 101, a controller 102, and a spray generator 103 as described above.

[0059] In use, the liquid storage tank 101 stores the liquid medicine, and the water guide pipe 21 in the spray generator 103 is connected to the liquid storage tank 101. The controller 102 controls the operation of the fan. It should also be noted that the fan is connected to the air collection chamber 12 and is located at the air inlet 14 of the air collection chamber 12 so that the fan generates gas flow to the spray generator 103. When the airflow flows from the air collection chamber 12 to the air outlet 13 under the action of the fan, the airflow channel 33 guides the airflow to the air guide column 32, and the area near the air guide column 32 forms the airflow negative pressure zone 34. The airflow negative pressure zone 34 causes the liquid outlet 22 located therein to flow out a water column, which is atomized by the cutting of the airflow in all directions. Therefore, the sprayer 100 can be used in scenarios such as spraying pesticides on crops. It has a good atomization effect and effectively solves the problem that the liquid needs to be converted into atomization by ultrasonic instruments in the existing technology. This brings problems such as complicated assembly and inconvenient operation to the spraying equipment during the production process. In addition, because the air guide plate is located far away from the water outlet, the liquid atomization is incomplete, the atomization is not fine, and the atomization effect is not good.

[0060] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
