[0080] The following is a detailed description of the nozzle kit 100, the aircraft, and the method for using the nozzle kit provided in the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0081] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the nozzle kit 100 includes a diverter assembly 110, the diverter assembly 110 is provided with an inlet end 111 and a plurality of outlet ends 112, the diverter assembly 110 is configured to be able to input a medium through the inlet end 111 and flow out the medium from the plurality of outlet ends 112 to divert the medium; an atomizer assembly 120, the atomizer assembly 120 is configured to be docked with the outlet end 112 to atomize the diverted medium; and a driving mechanism 130, the driving mechanism 130 is connected to the atomizer assembly 120 and / or the diverter assembly 110, the driving mechanism 130 is used to drive the atomizer assembly 120 and / or the diverter assembly 110 to rotate to atomize the medium; when atomizing, the difference between the rotation speed of the atomizer assembly 120 and the rotation speed of the diverter assembly 110 is greater than or equal to a preset value.

[0082] In the embodiment of the present application, the nozzle kit 100 includes a flow diversion component 110, an atomization component 120 and a driving mechanism 130. The atomization component 120 and / or the flow diversion component 110 are driven to rotate by the driving mechanism 130, and the medium enters the flow diversion component 110 through the inlet end 111 of the flow diversion component 110 and flows out from the multiple outlet ends 112 of the flow diversion component 110. Then, the flow diversion component 110 is used to realize the diversion of the medium, and the atomization component 120 is arranged relative to the outlet end 112 of the flow diversion component 110, and the medium diverted by the flow diversion component 110 is discharged to the atomization component 120. In this way, the medium diverted by the flow diversion component 110 is further atomized by the atomization component 120, and an atomized medium with a smaller particle size can be obtained, thereby improving the atomization effect of the nozzle kit 100.

[0083] Specifically, the flow diversion component 110 is provided with an inlet end 111 and a plurality of outlet ends 112 , and the medium to be sprayed can be introduced into the flow diversion component 110 through the inlet end 111 , and the introduced medium is then discharged from the plurality of outlet ends 112 , thereby achieving a flow diversion effect on the medium.

[0084] The atomizing assembly 120 is arranged opposite to the multiple outlet ends 112 of the flow dividing assembly 110, and the medium is discharged to the atomizing assembly 120 after being diverted by the flow dividing assembly 110, and the medium can be further atomized by the atomizing assembly 120. In addition, a driving mechanism 130 is arranged in the nozzle kit 100, and the flow dividing assembly 110 and / or the atomizing assembly 120 are connected to the driving mechanism 130, and at least one of the flow dividing assembly 110 and the atomizing assembly 120 can be driven to rotate by the driving mechanism 130 to realize centrifugal atomization of the medium.

[0085] Among them, when atomizing the medium, the difference between the rotation speed of the atomizing component 120 and the rotation speed of the diverter component 110 is set to be greater than or equal to a preset value, that is, the rotation speed of the atomizing component 120 is significantly different from the rotation speed of the diverter component 110. The larger speed difference can enable the medium after being diverted by the diverter component 110 to be fully cut and atomized by the atomizing component 120, thereby improving the atomization effect of the nozzle kit 100 on the medium.

[0086] It should be noted that the size of the preset value can be determined according to the particle size of the atomized medium sprayed by the nozzle kit 100, and those skilled in the art can set it according to actual atomization needs.

[0087] In some embodiments, the rotation speed of the atomizer assembly 120 is v, and the preset value is [v / 2, v]. In the embodiment of the present application, by setting a reasonable range of the preset value, the rotation speed of the atomizer assembly 120 is greater than the rotation speed of the diverter assembly 110, so that the medium after diversion by the diverter assembly 110 can be further atomized by the atomizer assembly 120 to improve the atomization effect.

[0088] Specifically, the preset value can be set to: 0.5v, 0.6v, 0.7v, 0.8v, 0.9v, v or any other value or a range between any two values.

[0089] It is understandable that the nozzle in the related art realizes the atomization of the medium through the rotational centrifugal effect. However, as the flow rate of the medium increases, the particle size of the medium sprayed by the nozzle will increase, affecting the atomization effect of the nozzle.

[0090] The nozzle kit 100 in the embodiment of the present application first diverts the medium through the diverting component 110, and then further atomizes the diverted medium through the atomizing component 120, so that the medium with a large flow rate can be atomized into an atomized medium with a smaller particle size. In addition, when atomizing, the difference between the rotation speed of the atomizing component 120 and the rotation speed of the diverting component 110 is set to be greater than or equal to a preset value, which can ensure that the atomizing component 120 further atomizes the diverted medium, thereby improving the atomization effect of the nozzle kit 100 on the medium.

[0091] Alternatively, if Figure 1 , Fig.16 and Fig.17 As shown, according to some embodiments of the present application, the nozzle kit 100 includes: a diverter assembly 110, the diverter assembly 110 is provided with an inlet end 111 and a plurality of outlet ends 112, the diverter assembly 110 is configured to be able to input a medium through the inlet end 111 and flow out the medium from the plurality of outlet ends 112 to divert the medium; the two ends of the outlet end 112 are respectively a first end 1121 and a second end 1122 which is farther away from the inlet end 111 than the first end 1121, and the size L2 of the inner wall of the second end 1122 is smaller than the size L1 of the inner wall of the first end 1121; and an atomizer assembly 120, the atomizer assembly 120 is configured to be docked with the outlet end 112, and can rotate to atomize the diverted medium.

[0092] In the embodiment of the present application, the nozzle kit 100 includes a flow diversion component 110 and an atomization component 120. The medium enters the flow diversion component 110 through the inlet end 111 of the flow diversion component 110 and flows out from the multiple outlet ends 112 of the flow diversion component 110, and then the flow diversion component 110 is used to realize the diversion of the medium. The atomization component 120 is arranged relative to the outlet end 112 of the flow diversion component 110. The medium diverted by the flow diversion component 110 is further atomized by the atomization component 120 again, and an atomized medium with a smaller particle size can be obtained. In addition, by setting the structure of the outlet end 112 of the flow diversion component 110, the inner wall size L2 of the second end 1122 of the outlet end 112 is smaller than the inner wall size L1 of the first end 1121. In this way, when the medium flows from the inlet end 111 to the outlet 112, a pressure difference will be generated between the first end 1121 and the second end 1122 due to the change in the internal structure of the diverter component 110, and the medium is in a compressed state. Under the action of the pressure difference, the diverter effect of the diverter component 110 on the medium can be enhanced, thereby further improving the atomization effect of the nozzle kit 100.

[0093] Specifically, the diversion component 110 includes an inlet end 111 and multiple outlet ends 112. The medium to be sprayed flows into the diversion component 110 through the inlet end 111 and is then discharged from the multiple outlet ends 112, thereby realizing the diversion effect on the medium. A rotatable atomization component 120 is correspondingly arranged at the outlet end 112 of the diversion component 110 so as to further atomize the diverted medium by utilizing the rotating centrifugal effect of the atomization component 120.

[0094] Among them, the outlet end 112 of the diversion component 110 includes a first end 1121 and a second end 1122, the first end 1121 is arranged close to the inlet end 111, and the second end 1122 is arranged away from the inlet end 111, and the size L2 of the inner wall of the second end 1122 is smaller than the size L1 of the inner wall of the first end 1121.

[0095] In some embodiments, reference Figure 2 and Figure 3 The flow dividing assembly 110 includes a housing 113 and a plurality of nozzles 115, wherein an inlet end 111 is disposed at one end of the housing 113, and a plurality of nozzles 115 are disposed at the other end of the housing 113 to form an outlet end 112 of the flow dividing assembly 110. Fig.16 As shown, the end of the nozzle 115 close to the shell 113 is the first end 1121, and the inner wall size of the first end 1121 is L1; the end of the nozzle 115 away from the shell 113 is the second end 1122, and the inner wall size of the second end 1122 is L2. The size L2 of the inner wall of the second end 1122 is smaller than the size L1 of the inner wall of the first end 1121, so that when the medium in the shell is sprayed out through the nozzle, the medium can be diverted under the action of the pressure difference.

[0096] In some embodiments, reference Fig.14 and Fig.15 As shown, the diverter assembly 110 includes a shell 113 and a diverter plate 116 docked with the shell 113. The shell is provided with an inlet end 111. The diverter plate 116 is arranged at one end of the shell 113 away from the inlet end 111. The outlet end 112 is formed by the diverter plate 116 and the shell 113. A plurality of diverter ports 1132 are provided on the circumferential outer side of the diverter plate 116.

[0097] It is understandable that if Fig.17 As shown, the outlet end 112 includes a first end 1121 and a second end 1122, the position close to the center of the diverter plate 116 is the first end 1121, and the position close to or located at the diverter port 1132 is the second end 1122. The inner wall size of the first end 1121 is L1, and the inner wall size of the second end 1122 is L2. The size L2 of the inner wall of the second end 1122 is set to be smaller than the size L1 of the inner wall of the first end 1121, so that a pressure difference is generated during the flow of the medium between the first end 1121 and the second end 1122, and the diversion effect of the medium can be achieved under the action of the pressure difference.

[0098] Optionally, refer to Figure 2 , Figure 3 , Fig.14 and Fig.15 As shown, the present application also provides a nozzle kit 100, which includes: a plurality of diverter components 110, the diverter components 110 are provided with an inlet end 111 and a plurality of outlet ends 112, the diverter components 110 are configured to be able to input a medium through the inlet end 111 and flow out the medium from the plurality of outlet ends 112 to divert the medium; an atomizer component 120, the atomizer component 120 is configured to be docked with the outlet end 112 to atomize the diverted medium; and a drive mechanism 130, the drive mechanism 130 is connected to the atomizer component 120, and is used to drive the atomizer component 120 to rotate.

[0099] The plurality of flow splitting components 110 include a first flow splitting component 110a (eg Figure 3 ) and a second flow dividing component 110b (as shown Fig.15 When the first flow diverter assembly 110a is selectively detachably connected to the atomizing assembly 120, a first nozzle is formed; when the second flow diverter assembly 110b is selectively detachably connected to the atomizing assembly 120, a second nozzle is formed; when the medium of the same pressure is input, the pressure of the medium at the outlet end 112 of the first flow diverter assembly 110a is different from the pressure of the medium at the outlet end 112 of the second flow diverter assembly 110b, so that the atomized particle size of the first nozzle is different from the particle size atomized by the second nozzle.

[0100] In the embodiment of the present application, the nozzle kit 100 includes a flow diversion component 110, an atomization component 120 and a driving mechanism 130. The medium enters the flow diversion component 110 through the inlet end 111 of the flow diversion component 110 and flows out from the multiple outlet ends 112 of the flow diversion component 110. Then, the flow diversion component 110 is used to realize the diversion of the medium. The medium after diversion is discharged to the atomization component 120. The atomization component 120 is driven to rotate by the driving mechanism 130 to further atomize the medium, so that an atomized medium with a smaller particle size can be obtained. In addition, by arranging multiple detachable flow diversion components 110 in the nozzle kit 100 and using different flow diversion components 110, the atomized particle size of the medium sprayed by the nozzle kit 100 is different, so that the atomization effect of the nozzle kit 100 can be adjusted to meet different spraying requirements and improve the applicability of the nozzle kit 100.

[0101] Specifically, a plurality of flow diversion components 110 are provided in the nozzle kit 100, each flow diversion component 110 is provided with an inlet end 111 and a plurality of outlet ends 112, and the medium enters the flow diversion component 110 from the inlet end 111 and is discharged from the plurality of outlet ends 112, thereby realizing the flow diversion effect on the medium.

[0102] The atomizing assembly 120 receives the medium flowing out from the outlet end 112 of the diverting assembly 110. The atomizing assembly 120 is connected to the driving mechanism 130. The atomizing assembly 120 is driven to rotate by the driving mechanism 130. The rotation of the atomizing assembly 120 generates centrifugal force, which can further atomize the diverted medium and further reduce the atomized particle size of the medium.

[0103] Among them, multiple diverter assemblies 110 are detachably connected to the atomizing assembly 120, which is convenient for replacing the diverter assemblies 110 in actual use. When different diverter assemblies 110 are connected to the atomizing assembly 120, the pressure of the medium output by the outlet end 112 of the diverter assemblies 110 is different, and then the diverting effect of the diverter assemblies 110 on the medium is different, and accordingly, the particle size of the atomized medium obtained after further atomization by the atomizing assembly 120 is different. In this way, the diverter assemblies 110 used for diversion can be flexibly selected according to the characteristics of the sprayed medium and the actual spraying requirements.

[0104] It should be noted that the atomized particle size in the present application refers to the particle size of each droplet in the mist medium sprayed by the nozzle kit 100 , and the average or median of the particle sizes of multiple droplets can be used as the atomized particle size of the nozzle kit 100 .

[0105] Alternatively, if Figure 1 As shown, the rotation speed of the atomizing assembly 120 is greater than the rotation speed of the diverter assembly 110 .

[0106] In an embodiment of the present application, by setting the rotation speed of the atomizing component 120 to be greater than the rotation speed of the diverter component 110, when the medium enters the atomizing component 120 after being diverted by the diverter component 110, it can be further centrifugally atomized by the atomizing component 120 with a higher rotation speed to ensure the atomization effect of the medium, and can further reduce the atomized particle size of the sprayed medium.

[0107] Specifically, the atomizing assembly 120 generates centrifugal force by rotating to achieve atomization of the medium. The flow splitting assembly 110 can adopt a pressure flow splitting method or a rotation centrifugal flow splitting method to achieve the flow splitting effect on the medium.

[0108] Among them, by setting the rotation speed of the atomizing component 120 to be greater than the rotation speed of the diverting component 110, no matter whether the diverting component 110 adopts pressure diversion or centrifugal diversion, the diverted medium is further centrifugally atomized by the atomizing component 120, so that a better atomization effect can be guaranteed.

[0109] Alternatively, if Figure 1 and Figure 2 As shown, the driving mechanism 130 driving the atomization assembly 120 to rotate is provided with a fixed part 131 and a rotating part 132 rotating relative to the fixed part 131, the rotating part 132 is connected to the atomization assembly 120 to drive the atomization assembly 120 to rotate, and the diverter assembly 110 is stationary relative to the fixed part 131 so that the rotation speed of the diverter assembly 110 is zero.

[0110] In the embodiment of the present application, the flow-dividing assembly 110 is connected to the fixing member 131 of the driving mechanism 130, the atomizing assembly 120 is connected to the rotating member 132 of the driving mechanism 130, and the atomizing assembly 120 is driven to rotate by the rotating member 132, so that the atomizing assembly 120 generates centrifugal force. In this way, the flow-dividing assembly 110 can be used to divert the medium of large flow, and then the medium after diversion flows through the atomizing assembly 120. Under the rotation centrifugal action of the atomizing assembly 120, the medium after diversion can be further atomized, ensuring the atomization effect of the medium. In addition, the flow-dividing assembly 110 is stationary relative to the fixing member 131 so that the rotation speed of the flow-dividing assembly 110 is zero, so that the difference between the rotation speed of the atomizing assembly 120 and the rotation speed of the flow-dividing assembly 110 is the largest, which can further ensure the atomization effect. In addition, the flow-dividing assembly 110 is stationary relative to the fixing member 131, and only the atomizing assembly 120 rotates, which can reduce the power consumption of the nozzle kit 100 and reduce the manufacturing cost.

[0111] Specifically, the driving mechanism 130 includes a fixed member 131 and a rotating member 132. The rotating member 132 can rotate relative to the fixed member 131. The flow splitting assembly 110 is connected to the fixed member 131 so that the flow splitting assembly 110 remains relatively still during the flow splitting process. The atomizing assembly 120 is connected to the rotating member 132. During the atomization process of the medium, the atomizing assembly 120 is driven to rotate relatively by the rotating member 132 to generate a rotating centrifugal force, thereby achieving further atomization of the medium.

[0112] In some embodiments, the drive mechanism 130 may be a motor drive mechanism, a hydraulic drive mechanism, a cylinder drive mechanism, or other rotary drive structures. The drive mechanism 130 may also be other types of rotary drive structures, and those skilled in the art may select them according to actual use, and this application does not limit this.

[0113] Exemplarily, the driving mechanism 130 can be a motor driving mechanism, which can include a motor body and a rotating shaft, which is rotatably connected to the motor body. The motor body is a fixed part 131, and the rotating shaft is a rotating part 132. The flow splitter assembly 110 is connected to the motor body, and the end of the rotating shaft away from the motor body passes through the flow splitter assembly 110 and is connected to the atomizer assembly 120.

[0114] In a specific application, the medium enters the diverter assembly 110 from the inlet end 111 of the diverter assembly 110, is diverted by the diverter assembly 110, and is discharged from the outlet end 112 of the diverter assembly 110. The atomizer assembly 120 is arranged opposite to the outlet end 112 of the diverter assembly 110. The atomizer assembly 120 can be driven to rotate by the rotating shaft, and then the medium discharged from the outlet end 112 of the diverter assembly 110 enters the high-speed rotating atomizer assembly 120, and the medium can be further atomized through the rotating centrifugal action of the atomizer assembly 120.

[0115] Alternatively, if Figure 2 As shown, Figure 2 The middle dotted line indicates the rotation axis of the atomizing assembly 120 , and the arrow indicates the medium spraying direction of the diverter assembly 110 . The medium spraying direction of the diverter assembly 110 is arranged to intersect with the direction of the rotation axis of the atomizing assembly 120 .

[0116] In the embodiment of the present application, the medium ejection direction of the flow splitter assembly 110 is arranged to intersect with the extension direction of the rotation axis of the atomizer assembly 120, so that the discharge direction of the medium after the flow splitter assembly 110 is corresponding to the centrifugal throwing direction of the atomizer assembly 120. In this way, the condensation of the medium after the flow splitter assembly 110 in the atomizer assembly 120 can be reduced, thereby improving the atomization effect of the atomizer assembly 120 on the medium after the flow splitter assembly 120. For example, the medium ejection direction of the flow splitter assembly 110 and the extension direction of the rotation axis of the atomizer assembly 120 can be configured to be vertical or approximately vertical.

[0117] The nozzle kit 100 in the present application is configured such that the medium spraying direction of the diverter component 110 intersects with the extension direction of the rotation axis of the atomizer component 120, that is, the medium spraying direction of the diverter component 110 corresponds to the throwing direction of the atomizer component 120. In this way, the atomizer component 120 can directly centrifugally atomize the diverted medium to avoid the diverted medium colliding with the inside of the atomizer component 120 and forming condensation.

[0118] Alternatively, if Figure 2 As shown, the liquid outlet 121 of the atomizing assembly 120 and the outlet end 112 of the flow dividing assembly 110 are arranged along the radial direction of the atomizing assembly 120 , and the liquid outlet 121 is arranged on the outside of the outlet end 112 .

[0119] In the embodiment of the present application, the liquid outlet 121 of the atomizing assembly 120 and the outlet end 112 of the diverting assembly 110 are arranged along the radial direction of the atomizing assembly 120, and the liquid outlet 121 of the atomizing assembly 120 is arranged outside the outlet end 112 of the diverting assembly 110. In this way, the medium diverted by the diverting assembly 110 is sprayed from the outlet end 112 to the liquid outlet 121 of the atomizing assembly 120, and the diverted medium is further centrifugally atomized by the rotating centrifugal action of the atomizing assembly 120, and discharged from the liquid outlet 121, thereby achieving the atomization effect of the medium.

[0120] Specifically, along the radial direction of the atomizing assembly 120, the liquid outlet 121 of the atomizing assembly 120 is located outside the outlet end 112 of the diverter assembly 110, and the medium diverted by the diverter assembly 110 is directly discharged to the liquid outlet 121 of the atomizing assembly 120, which can reduce the condensation phenomenon caused by the collision and splashing of the flowing medium with the inside of the atomizing assembly 120. After the atomized medium is sprayed out from the liquid outlet 121 of the atomizing assembly 120, it moves in a direction away from the outlet end 112 of the diverter assembly 110.

[0121] Alternatively, if Figure 2 As shown, the atomizing assembly 120 includes a bottom 122 and a side portion 123 erected on the bottom 122 , the side portion 123 is provided with a plurality of liquid outlets 121 at intervals, and the flow dividing assembly 110 is located on the inner side of the side portion 123 .

[0122] In the embodiment of the present application, the atomization assembly 120 includes a bottom 122 and a side 123, and a plurality of liquid outlets 121 are provided on the side 123. The diverter assembly 110 is arranged on the inner side of the side 123. The driving mechanism 130 can be used to drive the bottom 122 to rotate, and the side 123 can be driven to rotate through the bottom 122. The medium diverted by the diverter assembly 110 is discharged to the side 123 on the bottom 122. After the medium hits the high-speed rotating side 123, it is broken up by the side 123 and thrown out from the liquid outlet 121, thereby realizing the atomization effect on the medium.

[0123] Specifically, the side portion 123 can be arranged around the bottom 122, and a plurality of liquid outlets 121 are provided on the side portion 123 along the circumferential direction, and the plurality of liquid outlets 121 are arranged at intervals, so that the bottom 122 can be connected to the rotating member 132 of the driving mechanism 130, and the bottom 122 is driven to rotate by the rotating member 132, and the side portion 123 is driven to rotate by the bottom 122 to generate a centrifugal force, so that the medium is discharged from the outlet end 112 of the diversion component 110 and flows to the surface of the side portion 123, and the medium can be atomized under the rotational centrifugal action of the side portion 123.

[0124] Among them, multiple liquid outlets 121 can be arranged at intervals along the circumference of the side 123. When the medium contacts the surface of the side 123, the high-speed rotation of the side 123 can break up the medium into atomized particles with smaller particle sizes. The atomized particles are thrown out from the liquid outlet 121 and move in a direction away from the diversion component 110, thereby realizing the atomization of the medium.

[0125] Alternatively, if Figure 2 As shown, the atomizing assembly 120 includes a plurality of liquid-separating columns 123 a or liquid-separating teeth 123 a , and the plurality of liquid-separating columns 123 a or the plurality of liquid-separating teeth 123 a are disposed around the bottom 122 to form a side portion 123 .

[0126] In the embodiment of the present application, multiple liquid separator columns 123a or multiple liquid separator teeth 123a are arranged around the bottom 122, and the multiple liquid separator columns 123a or multiple liquid separator teeth 123a are arranged at intervals. There is a gap between two adjacent liquid separator columns 123a or two adjacent liquid separator teeth 123a, and the gap forms a liquid outlet 121.

[0127] In a specific application, the rotation of the bottom 122 can drive multiple liquid separation columns 123a or multiple liquid separation teeth 123a to rotate. When the medium diverted by the diversion component 110 flows to the liquid separation column 123a or the liquid separation tooth 123a, the rotating liquid separation column 123a or the liquid separation tooth 123a further breaks up the diverted medium and throws it out from the gap, thereby achieving further atomization of the medium.

[0128] Alternatively, if Figure 2 As shown, the distances between two adjacent liquid separation columns 123 a or between two adjacent liquid separation teeth 123 a are equal.

[0129] In the embodiment of the present application, by setting the spacing between two adjacent liquid separation columns 123a or between two adjacent liquid separation teeth 123a to be equal, the atomization component 120 can make the atomization effect of the diverted medium more uniform, thereby improving the atomization effect.

[0130] The distance between two adjacent liquid separation columns 123 a or between two adjacent liquid separation teeth 123 a can be determined according to the performance of the medium and the actual atomization requirements, and the present application does not impose any limitation on this.

[0131] In the embodiment of the present application, the atomizing assembly 120 includes a bottom 122 and a side portion 123 arranged around the bottom 122, and a plurality of liquid outlets 121 are arranged on the side portion 123. The bottom 122 is provided with a receiving cavity 1221 facing the flow dividing assembly 110 for receiving the medium flowing out of the flow dividing assembly 110.

[0132] In some embodiments, the bottom 122 is concave, forming a receiving cavity 1221 surrounding the rotation axis of the atomizer assembly 120 .

[0133] For example, Fig.18 As shown, the bottom 122 is recessed downward to form a receiving chamber 1221, which is used for the residual medium in the diverter assembly 110 to flow into the receiving chamber 1221 for storage when the operation is stopped and the nozzle assembly 100 stops atomizing liquid, so as to prevent the medium from flowing to the crops. In particular, when the aircraft attitude changes, the residual medium in the diverter assembly 110 is easy to flow out. The bottom 122 with the receiving chamber 1221 can prevent the medium from flowing to the crops compared with the flat bottom. The residual medium in the atomization assembly 120 can be manually cleaned and discharged or saved for spraying in the next operation.

[0134] Furthermore, the bottom 122 is provided with a dividing rib 1222 located in the accommodating cavity 1221 for dividing the accommodating cavity 1221 into a plurality of areas, so that the residual medium in each direction of the atomizing assembly 120 tends to be uniform.

[0135] Furthermore, the bottom 122 is provided with a guide portion 1223 close to the liquid outlet, and the guide portion 1223 is used to guide the medium, so that the medium can be first guided and refined by the guide portion 1223, and then further broken up and atomized by the liquid separator column 123a or the liquid separator tooth 123a, thereby further improving the atomization effect.

[0136] In the embodiment of the present application, a detachable connection is provided between the diverter assembly 110 and the atomizer assembly 120 and the drive mechanism 130, thereby facilitating the assembly and disassembly of the nozzle kit 100, so that the various components in the nozzle kit 100 can be flexibly disassembled and replaced according to actual usage requirements.

[0137] Alternatively, if Figure 2 and Fig.14 As shown, the spray head kit 100 further includes a connecting bracket 140 connected to the driving mechanism 130 , and the flow dividing assembly 110 is detachably connected to the connecting bracket 140 .

[0138] In the embodiment of the present application, a connecting bracket 140 is provided between the flow diverter assembly 110 and the driving mechanism 130, and the flow diverter assembly 110 is installed on the driving mechanism 130 through the connecting bracket 140, and the connecting bracket 140 and the flow diverter assembly 110 are detachably connected, so as to facilitate the disassembly and replacement of the flow diverter assembly 110. In addition, by providing the connecting bracket 140, the connecting bracket 140 can be used to isolate the driving mechanism 130 from the flow diverter assembly 110, so as to prevent the medium in the flow diverter assembly 110 from entering the driving mechanism 130 and affecting the performance of the driving mechanism 130, thereby improving the service life of the driving mechanism 130.

[0139] Specifically, by providing a connecting bracket 140 , one end of the connecting bracket 140 is connected to the driving mechanism 130 , and the other end of the connecting bracket 140 is detachably connected to the diverter assembly 110 , thereby facilitating assembly and disassembly between the diverter assembly 110 and the connecting bracket 140 .

[0140] In some embodiments, one of the buckles or slots can be set on the connecting bracket 140, and the other of the buckles or slots can be set on the diverter assembly 110. Through the snap-fitting of the buckles or slots, a detachable connection between the diverter assembly 110 and the connecting bracket 140 can be achieved, thereby facilitating the installation and disassembly between the diverter assembly 110 and the connecting bracket 140.

[0141] Of course, other detachable structures may also be used to achieve a detachable connection between the connecting bracket 140 and the diversion component 110. Those skilled in the art may select them according to actual needs, and this application does not impose any limitation thereto.

[0142] Alternatively, if Figure 2 and Fig.14 As shown, the rotating shaft of the driving mechanism 130 passes through the connecting bracket 140 and the diverter assembly 110 in sequence and is detachably connected to the atomizer assembly 120. The diverter assembly 110 is located on the inner side of the atomizer assembly 120, and the connecting bracket 140 and the diverter assembly 110 are snap-fitted together. When the atomizer assembly 120 is removed from the rotating shaft, the diverter assembly 110 and the connecting bracket 140 are released from the snap-fit ​​lock to achieve the disassembly of the diverter assembly 110.

[0143] In an embodiment of the present application, the connecting bracket 140 is connected to the driving mechanism 130, and the diverter assembly 110 is detachably connected to the connecting bracket 140 through a snap fit, and the rotating shaft of the driving mechanism 130 passes through the connecting bracket 140 and the diverter assembly 110 in sequence and is detachably connected to the atomizer assembly 120.

[0144] When disassembling the nozzle kit 100, the atomizing assembly 120 can be disassembled from the rotating shaft first, and then the buckle lock between the flow dividing assembly 110 and the connecting bracket 140 can be released, so that the flow dividing assembly 110 and the atomizing assembly 120 can be disassembled from the driving mechanism 130. In this way, it is easy to disassemble and replace the flow dividing assembly 110 and the atomizing assembly 120, and the actual assembly and maintenance operations are convenient.

[0145] Alternatively, if Figure 6 As shown, the flow dividing component 110 includes a shell 113 and a pre-dividing fluid 114. The shell 113 is provided with a cavity 1131 and an inlet end 111 and an outlet end 112 connected to the cavity 1131. The pre-dividing fluid 114 is arranged in the cavity 1131 and docked with the inlet end 111, and is used to divide the medium flowing in from the inlet end 111 into at least two paths so as to flow to different outlet ends 112.

[0146] In the embodiment of the present application, a cavity 1131 is provided in the housing 113 of the flow splitter assembly 110, and a pre-split fluid 114 is provided in the cavity 1131, so that the pre-split fluid 114 is arranged opposite to the inlet end 111, and when the medium flows into the cavity 1131 through the inlet end 111, the medium flows through the pre-split fluid 114 and is split by the pre-split fluid 114. Thus, the medium entering the cavity 1131 flows to different outlet ends 112 along different paths, and the medium is prevented from directly flowing to the outlet end 112 along the shortest flow path after entering the cavity 1131, and it is ensured that the medium entering the cavity 1131 can flow out from different outlet ends 112 to achieve the diversion effect on the medium, thereby improving the flow uniformity of the medium in the cavity 1131, and further improving the diversion effect of the flow splitter assembly 110 on the medium.

[0147] It is understandable that after the external medium enters the cavity 1131 in the shell 113, since the medium has a certain flow velocity, the flowing medium usually flows to the outlet end 112 of the shell 113 at the shortest distance. This will cause uneven distribution of the medium at various positions in the cavity 1131, affecting the diversion effect of the diversion component 110 on the medium.

[0148] The nozzle kit 100 in the embodiment of the present application is provided with a pre-distribution fluid 114 in the cavity 1131 of the housing 113, and the pre-distribution fluid 114 is arranged opposite to the inlet end 111 in the housing 113. When the external medium flows into the cavity 1131 from the inlet end 111, the flowing medium is sheared and diverted by the pre-distribution fluid 114, so that the flowing medium flows along different paths. Thus, the medium enters the cavity 1131 of the housing 113, can flow and fill to different positions in the cavity 1131, and then flows out from different outlet ends 112 in the diversion component 110, so as to further divert the medium, so that the medium distribution after diversion is more uniform.

[0149] In some embodiments, Figure 6 As shown, the pre-distributor 114 includes a first baffle 1141 and a second baffle 1142 , which are spaced apart in the cavity 1131 of the shell 113 , and are both disposed opposite to the inlet end 111 .

[0150] In a specific application, the external medium flows into the cavity 1131 through the inlet end 111 of the shell 113, and is sheared and split by the first baffle 1141 and the second baffle 1142, so that the flowing medium can be divided into three flow branches (such as Figure 6 The three flow branches after diversion flow toward the outlet end 112 of the shell 113 along three different paths respectively, thereby preventing the medium from flowing into the cavity 1131 of the shell 113 and then flowing out of the shell 113 along the shortest flow path.

[0151] It should be noted that the pre-dividing fluid 114 in the present application may also use other diverting structures, and those skilled in the art may configure them according to actual needs, and the present application does not impose any limitation thereto.

[0152] Alternatively, if Figure 3 As shown, the flow diversion component 110 includes: a shell 113, the shell 113 is provided with a plurality of nozzles 115 forming an outlet end 112; an inlet end 111 is provided in the shell 113, the medium enters the shell 113 through the inlet end 111, and the medium in the shell 113 is sprayed toward the atomization component 120 through the plurality of nozzles 115.

[0153] In the embodiment of the present application, by setting a plurality of nozzles 115 in the shell 113, the medium entering the shell 113 is sprayed out through the plurality of nozzles 115, which can achieve a primary flow diversion effect on the medium, and then the medium sprayed out of the nozzle 115 is further atomized by the atomization component 120, thereby improving the atomization effect.

[0154] Specifically, the flow dividing assembly 110 includes a housing 113 and a plurality of nozzles 115. A cavity 1131 is provided in the housing 113. An inlet end 111 is provided in the housing 113, and the inlet end 111 is communicated with the cavity 1131. A plurality of nozzles 115 are provided at one end of the housing 113 away from the inlet end 111, and the plurality of nozzles 115 are communicated with the cavity 1131 in the housing 113 to form an outlet end 112.

[0155] In a specific application, the medium enters the cavity 1131 of the housing 113 through the inlet end 111. Under the flow pressure of the medium, the medium in the cavity 1131 is sprayed from the multiple nozzles 115 to achieve preliminary atomization of the medium. The medium sprayed from the multiple nozzles 115 is sprayed toward the atomizing assembly 120, and then the atomizing assembly 120 further atomizes the medium to obtain a mist medium with a smaller particle size, thereby improving the overall atomization effect of the nozzle kit 100.

[0156] Alternatively, if Figure 3 As shown, a plurality of nozzles 115 are arranged at intervals along the circumference of the housing 113. In the embodiment of the present application, a plurality of nozzles 115 are arranged in the housing 113, and the plurality of nozzles 115 are arranged at intervals along the circumference of the housing 113, so that the medium in the cavity 1131 can be ejected from the plurality of nozzles 115 at the same time, and the preliminary atomization of the medium can be achieved while the flow of the medium is diverted, and then the plurality of nozzles 115 evenly spray the medium toward the atomization assembly 120, so that the atomization assembly 120 can be used to further atomize the medium and improve the uniformity of atomization.

[0157] It can be understood that since the spraying range of each nozzle 115 is limited, in order to increase the coverage of the medium after diversion by the entire diversion assembly 110, multiple nozzles 115 can be arranged at circumferential intervals along the shell 113, which helps to improve the coverage of the medium output by the entire diversion assembly 110 to the atomization assembly 120.

[0158] The spraying directions of the multiple nozzles 115 can be set to be parallel to each other, that is, the multiple nozzles 115 spray the medium toward the atomizing assembly 120 in the same direction. The spraying directions of the multiple nozzles 115 can also be set to intersect with each other, that is, the multiple nozzles 115 spray the medium toward the atomizing assembly 120 in different directions.

[0159] Alternatively, if Figure 1 , Figure 4 and Figure 5 As shown, the height of the liquid outlet 121 of the atomizing assembly 120 is H, the spraying radius of the nozzle 115 is L, and the angle of the liquid film thickness sprayed by the nozzle 115 is θ, which satisfies: H≥2L·sin(θ / 2).

[0160] In the embodiment of the present application, the relationship between the height H of the liquid outlet 121 of the atomizing assembly 120, the spraying radius L of the nozzle 115, and the angle θ of the liquid film thickness sprayed by the nozzle 115 is set so that the medium sprayed by the nozzle 115 can be covered by the liquid outlet 121 of the atomizing assembly 120. In this way, it is prevented that the medium sprayed by the nozzle 115 is directly discharged without being atomized by the atomizing assembly 120, thereby ensuring that the medium sprayed by the nozzle 115 can be re-atomized by the atomizing assembly 120, thereby ensuring the overall atomization effect of the nozzle kit 100.

[0161] The height H of the liquid outlet 121 of the atomizing assembly 120 refers to the height dimension of the liquid outlet 121 of the atomizing assembly 120 along the direction of the rotation axis of the atomizing assembly 120. In the direction perpendicular to the rotation axis of the atomizing assembly 120, the medium sprayed by each nozzle 115 is distributed in a fan-shaped structure, and the spraying radius L of the nozzle 115 refers to the distance from the edge of the fan-shaped structure to the rotation axis in the direction perpendicular to the rotation axis of the atomizing assembly 120.

[0162] In addition, when the medium is sprayed out from the nozzle 115, it will diffuse outward at a certain angle, and the angle is the spray liquid film thickness angle θ corresponding to the nozzle 115. The spray liquid film thickness angle θ of each nozzle 115 can be determined according to its specific structural characteristics, and those skilled in the art can determine the angle value of the spray liquid film thickness angle θ corresponding to the characteristics of the actually selected nozzle 115, and the present application does not limit it here.

[0163] Alternatively, if Figure 5 As shown, the spraying ranges of two adjacent nozzles 115 at least partially intersect.

[0164] In the embodiment of the present application, by arranging a plurality of nozzles 115 on the housing 113, the medium in the housing 113 is sprayed toward the atomizing assembly 120 via the nozzles 115, so as to realize a primary flow diversion of the medium, and the spraying ranges of two adjacent nozzles 115 among the plurality of nozzles 115 are arranged to at least partially intersect. In this way, it is possible to avoid the presence of areas between the plurality of nozzles 115 where the sprayed medium is not covered, thereby increasing the effective coverage area of ​​the nozzles 115 in the entire diversion assembly 110 and improving the uniformity of the medium spraying.

[0165] It can be understood that multiple nozzles 115 are arranged at intervals along the circumference of the shell 113, and the medium is sprayed out through the nozzles 115 to form a fan-shaped spraying area. By setting the distance between two adjacent nozzles 115 in the shell 113, the fan-shaped spraying areas formed by the two adjacent nozzles 115 are at least partially intersected, so that a complete annular spraying area can be formed by the multiple nozzles 115.

[0166] It should be noted that the location and number of the multiple nozzles 115 in the shell 113 can be determined according to the structure of the shell 113 and the spraying range of each nozzle 115. By reasonably setting the number and location of the nozzles 115 in the shell 113, the spraying ranges of two adjacent nozzles 115 can at least partially intersect.

[0167] Alternatively, if Fig.11 As shown, the spraying direction of the nozzle 115 is parallel to the rotation axis direction of the atomizing assembly 120 .

[0168] In the embodiment of the present application, the atomizing assembly 120 can be driven to rotate by the driving mechanism 130, and the spraying direction of the nozzle 115 is set to be parallel to the rotation axis direction of the atomizing assembly 120, so that the medium sprayed by the nozzle 115 can enter the interior of the atomizing assembly 120, and then the medium is further atomized by the centrifugal action of the rotation of the atomizing assembly 120, so as to enhance the atomization effect of the nozzle kit 100.

[0169] It can be understood that the atomizing assembly 120 realizes atomization of the medium through the rotational centrifugal action, and the flow direction of the medium atomized by the atomizing assembly 120 intersects with the direction of the rotation axis of the atomizing assembly 120. In the present application, the spraying direction of the nozzle 115 is set to be parallel to the direction of the rotation axis of the atomizing assembly 120, that is, the spraying direction of the nozzle 115 intersects with the flow direction of the medium atomized by the atomizing assembly 120, so that it can be ensured that the medium sprayed by the nozzle 115 can be further atomized through the rotational centrifugal action of the atomizing assembly 120, and the medium sprayed through the nozzle 115 is prevented from being directly discharged without passing through the atomizing assembly 120, which affects the atomization effect of the nozzle kit 100.

[0170] In some embodiments, Fig.12 As shown, an opening 124 is provided in the spraying direction in the atomizing assembly 120. By providing the opening 124 in the spraying direction of the nozzle 115 in the atomizing assembly 120, the medium atomized by the atomizing assembly 120 can also be discharged from the opening 124, so that the spraying coverage of the entire nozzle kit 100 can be improved.

[0171] In addition, when the nozzle 115 sprays the medium toward the atomizing assembly 120, part of the medium will collide with the atomizing assembly 120 to cause splashing and condensation, and the condensed medium will lose the atomization effect after being centrifugally thrown out. By providing the atomizing assembly 120 with an opening 124 located in the spraying direction, the condensation phenomenon caused by the splashing of the medium and the atomizing assembly 120 can be reduced. At the same time, the rotation of the atomizing assembly 120 drives the rotation of the opening 124, so that the medium sprayed toward the opening 124 can be dispersed and atomized, thereby achieving the atomization effect on the medium.

[0172] Among them, the number and positions of the openings 124 set in the atomization assembly 120 can correspond to the number and positions of the nozzles 115 in the shell 113. The specific settings can be determined according to actual usage, and this application does not impose any restrictions here.

[0173] Alternatively, if Figure 7 and Figure 8As shown, the shell 113 includes: a first shell portion 113a and a first shell portion 113b; the first shell portion 113a is detachably connected to the first shell portion 113b, and the inlet end 111 is arranged at the first shell portion 113a; a first nozzle portion 115a is arranged on the side of the first shell portion 113a facing the first shell portion 113b, and a second nozzle portion 115b is arranged on the side of the first shell portion 113b facing the first shell portion 113a, and the first nozzle portion 115a and the second nozzle portion 115b cooperate to form the nozzle 115.

[0174] In the embodiment of the present application, the shell 113 in the diversion assembly 110 is set as a split structure, and accordingly, the nozzle 115 is also set as a split structure, wherein the first nozzle part 115a is set on the first shell part 113a, and the second nozzle part 115b is set on the first shell part 113b. The detachable connection between the first shell part 113a and the first shell part 113b facilitates the disassembly of the nozzle 115, and then facilitates the cleaning and maintenance of the inside of the nozzle 115, thereby improving the service life of the nozzle 115.

[0175] Specifically, the housing 113 is provided with a plurality of nozzles 115, each nozzle 115 includes a first nozzle portion 115a and a second nozzle portion 115b, the plurality of first nozzle portions 115a are all provided on the first housing portion 113a, and the plurality of second nozzle portions 115b are all provided on the first housing portion 113b. When the first housing portion 113a is connected to the first housing portion 113b, each first nozzle portion 115a is matched with a second nozzle portion 115b to form a nozzle 115. It should be noted that, if Figure 8 and Fig. 9 As shown, the first nozzle portion 115a and the second nozzle portion 115b can be two equal-sized structures set in half, or can be structures of different sizes. No limitation is made here. It is only necessary to ensure that the first nozzle portion 115a and the second nozzle portion 115b can be combined to form the first nozzle portion 115a and the second nozzle portion 115b of the nozzle 115.

[0176] It is understandable that when the nozzle 115 sprays the medium, it is easily affected by impurities in the medium, causing blockage inside the nozzle 115. In the present application, the shell 113 and the nozzle 115 are both set as a split structure so that the shell 113 and the nozzle 115 can be disassembled, thereby facilitating the cleaning operation of the nozzle 115.

[0177] Alternatively, if Fig.10 As shown, the housing 113 includes: a first housing portion 113a and a first housing portion 113b; the first housing portion 113a is detachably connected to the first housing portion 113b, the inlet end 111 is disposed at the first housing portion 113a; and the nozzle 115 is disposed at the first housing portion 113b.

[0178] In the embodiment of the present application, the housing 113 includes a first housing portion 113a and a first housing portion 113b. By providing a detachable connection between the first housing portion 113a and the first housing portion 113b, the housing 113 can be easily disassembled to clean and maintain the interior of the housing 113. At the same time, by providing the housing 113 with a split structure, when an abnormality occurs locally in the housing 113, only the abnormal part needs to be disassembled and replaced, thereby reducing the use cost of the diverter assembly 110.

[0179] In some examples, the first housing portion 113a and the first housing portion 113b can be fixed by snapping, so as to facilitate the disassembly and installation of the first housing portion 113a and the first housing portion 113b. Specifically, a snap structure can be provided between the first housing portion 113a and the first housing portion 113b, and the snap structure can be used to achieve the snap-fit ​​fixation of the first housing portion 113a and the first housing portion 113b.

[0180] Of course, other detachable connection methods may be used between the first shell portion 113a and the first shell portion 113b, and those skilled in the art may configure them according to actual needs, and this application does not impose any limitation thereto.

[0181] In some instances, such as Fig.19 As shown, a leakage hole 1133 is provided at the bottom of the shell 113 in the diverter assembly 110, and the leakage hole 1133 is equipped with a leakage valve 1134, the leakage hole 1133 is docked with the inlet end 111, and the channel where the leakage hole 1133 docks with the inlet end 111 is communicated with the inner cavity of the shell 113. Among them, the leakage valve 1134 is a resettable elastic valve. When the medium enters the inlet end 111, the medium pressure causes the valve core 11341 of the leakage valve 1134 to be stamped, closing the leakage hole 1133, and the medium entering the shell 113 flows into the inner cavity of the shell 113, thereby being sprayed out from the nozzle 115 to complete the normal atomization operation. When the operation is stopped, due to the lack of medium pressure, the leakage valve automatically resets, so that the leakage hole opens, thereby automatically and centrally discharging the residual medium of the diverter assembly 110. For example, the remaining medium is discharged in a centralized manner at the end of the field where the operation is stopped, or the atomizing assembly 120 is set to delay stopping, so that the remaining medium is thrown out and atomized.

[0182] In some embodiments, Fig.14 As shown, the flow splitter assembly 110 may include a housing 113 and a flow splitter plate 116 docked with the housing 113, the inlet end 111 is provided at the housing 113, and the flow splitter plate 116 is provided with a plurality of flow splitters 1132. The plurality of flow splitters 1132 are used to split the medium, and the flow splitters 1132 are the outermost ends of the outlet end 112.

[0183] In the embodiment of the present application, when the medium enters the housing 113, the flowing medium has a certain kinetic energy, so that the flowing medium will flow out from the diversion port 1132 on the housing 113. In this way, the medium in the housing 113 can be diverted through the multiple diversion ports 1132 to divide the medium with a larger flow into multiple medium branches with relatively smaller flow, and then the atomization component 120 further atomizes the medium branches, thereby improving the atomization effect of the medium.

[0184] Among them, reference Fig.17 As shown, in the flow splitter assembly 110, the two ends of the outlet end 112 are respectively a first end 1121 and a second end 1122 which is farther from the inlet end 111 than the first end 1121, wherein the second end 1122 of the outlet end 112 is formed by the flow splitter 1132. That is, the outermost end of the outlet end 112 in the present application is the second end 1122, and when the medium in the flow splitter assembly 110 flows out through the flow splitter 1132, the medium is split under the action of the fluid pressure.

[0185] In the embodiment of the present application, the diverter plate 116 may be detachably connected to the housing 113 to facilitate replacement of the diverter plate 116 .

[0186] Specifically, a cavity 1131 is provided in the shell 113 of the diverter assembly 110, and the shell 113 is provided with an inlet end 111 connected to the cavity 1131. The diverter disk 116 is connected to one end of the shell 113 facing the atomization assembly 120. The outlet end 112 of the diverter assembly 110 is formed by the diverter disk 116. A plurality of diverter ports 1132 are provided on the side wall of the diverter disk 116. The plurality of diverter ports 1132 can be arranged at intervals along the circumference of the diverter disk 116.

[0187] It should be noted that the same nozzle kit 100 can be configured with multiple diverter plates 116, and the structures of the liquid diverter ports on different diverter plates 116 are different. The liquid diverter ports with different structures have different diverting effects on the medium, so as to achieve different diverting effects. Among them, the structure of the liquid diverter ports in the diverter plate 116 can be changed by setting parameters such as the number, spacing, and structural dimensions of the liquid diverter ports in each diverter plate 116.

[0188] In this way, in specific applications, the diversion effect of the diversion component 110 on the medium can be changed by replacing the diversion plate 116 in the diversion component 110, so that the diversion plate 116 can be flexibly selected according to the actual usage scenario to achieve different atomization effects, thereby improving the applicability of the nozzle kit 100.

[0189] Alternatively, if Fig. 20As shown, an embodiment of the present application also provides an aircraft, including: a fuselage 210, an arm 220, a power unit 230 and the nozzle kit 100 in the above embodiment, the arm 220 is connected to the fuselage 210, the power unit 230 is arranged on the arm 220 to provide flight power for the aircraft, and the nozzle kit 100 is arranged on the arm 220 and is located below the power unit 230.

[0190] In the embodiment of the present application, a power device 230 is arranged on the aircraft arm 220, and the power device 230 can be used to provide power for the aircraft, thereby driving the aircraft to fly, and a nozzle kit 100 is arranged on the aircraft arm 220. The nozzle kit 100 includes a flow diversion component 110, an atomization component 120, and a driving mechanism 130. The atomization component 120 and / or the flow diversion component 110 are driven to rotate by the driving mechanism 130, and the medium enters the flow diversion component 110 through the inlet end 111 of the flow diversion component 110, and flows out from the multiple outlet ends 112 of the flow diversion component 110, and then the flow diversion component 110 is used to realize the diversion of the medium, and the atomization component 120 and the outlet end 112 of the flow diversion component 110 are arranged relative to each other, and the medium after diversion by the flow diversion component 110 is discharged to the atomization component 120. In this way, the medium after being diverted by the diverter assembly 110 is further atomized by the atomizer assembly 120, so that atomized medium with a smaller particle size can be obtained, thereby improving the atomization effect of the nozzle kit 100. And through the movement of the aircraft, the medium can be sprayed onto different target objects, thereby improving the spraying efficiency.

[0191] Specifically, the aircraft includes a fuselage 210 and an arm 220, the arm 220 is connected to the fuselage 210, a power device 230 is arranged on the arm 220, and the power device 230 is used to provide power for the aircraft so as to drive the aircraft to move. A nozzle kit 100 is arranged on the arm 220, and the nozzle mechanism can realize the atomization of a medium with a large flow rate. In this way, the aircraft is driven to move between different target objects by the power device 230, and the nozzle kit 100 atomizes the medium so as to spray the atomized medium onto different target objects.

[0192] Furthermore, if Fig. 20 As shown, the nozzle kit 100 is arranged below the power device 230. When the power device 230 provides power to the aircraft, it will drive the airflow around it. Since the power device 230 is located above the nozzle kit 100, the airflow driven by the power device 230 will act on the medium sprayed by the nozzle kit 100. In this way, it is helpful to control the spraying range of the nozzle kit 100 through the power device 230, so as to improve the accuracy of the medium sprayed by the nozzle kit 100, thereby reducing the waste of the sprayed medium.

[0193] In some embodiments, Fig. 20 As shown, the power device 230 may include a propeller, which is rotatably connected to the arm 220. The high-speed rotation of the propeller can provide power for the aircraft, and the rotation of the propeller can be used to control the movement of the aircraft so as to spray the atomized medium of the nozzle kit 100 onto the target object.

[0194] In some embodiments, a liquid storage tank can also be provided on the body 210 or the arm 220, and the liquid storage tank is used to store the medium to be sprayed. The liquid storage tank is connected to the inlet end 111 of the diversion assembly 110 in the nozzle kit 100, and then the liquid storage tank continuously provides the spraying medium to the nozzle kit 100 to meet the spraying requirements of the medium.

[0195] In some embodiments, Fig.21 As shown, a fixing rod 170, a conduit 150 and a control valve 160 may also be provided, and the nozzle kit 100 is mounted on the fixing rod 170, and the nozzle kit 100 may be mounted and fixed on the machine arm 220 by using the fixing rod 170. The inlet end 111 of the flow dividing assembly 110 is connected to the liquid storage tank through the conduit 150, and a control valve 160 is provided in the conduit 150, and the control valve 160 may control the disconnection or conduction of the conduit 150, thereby controlling the precise supply of liquid from the liquid storage tank to the flow dividing assembly 110 of the nozzle kit 100.

[0196] Among them, the control valve 160 can be a valve with a structure such as a ball valve, a butterfly valve, a gate valve, a plug valve, a plunger valve, a solenoid valve, etc. Of course, other types of valves can also be selected. Technical personnel in this field can determine it according to the characteristics of the spraying medium and the actual working conditions. The embodiment of the present application does not limit this.

[0197] Optionally, the present application also provides a method for using the nozzle kit, referring to Fig. 22 , a flow chart showing a method for using a nozzle kit according to an embodiment of the present application is shown, and the specific steps of the method include the following:

[0198] Step 101, detachably connect the first diverter component 110a and the atomizer component 120 to form a first nozzle; wherein the first diverter component 110a is provided with a first inlet end and a plurality of first outlet ends, the first diverter component 110a is configured to be able to input a medium through the first inlet end and to flow out the medium from the plurality of first outlet ends to divert the medium; the atomizer component 120, the atomizer component 120 is configured to be used to atomize the diverted medium.

[0199] In the embodiment of the present application, the first diverter component 110a is provided with a first inlet end and a plurality of first outlet ends. The medium enters the first diverter component 110a from the first inlet end of the first diverter component 110a and flows out from the plurality of first outlet ends, thereby realizing the diversion effect on the medium.

[0200] When the first flow diversion component 110a is connected to the atomization component 120, the medium diverted by the first flow diversion component 110a is discharged from the first outlet and flows to the atomization component 120. The medium can be further atomized by the atomization component 120, thereby improving the atomization effect of the medium.

[0201] Step 102 , separating the first flow diversion component 110 a from the atomization component 120 .

[0202] Step 103, the second diverter component 110b is selectively detachably connected to the atomizing component 120 to form a second nozzle; the second diverter component 110b is provided with a second inlet end and a plurality of second outlet ends, and the second diverter component 110b is configured to be able to input a medium through the second inlet end and to flow out the medium from the plurality of second outlet ends to divert the medium; when inputting a medium of the same pressure, the pressure of the medium at the first outlet end of the first diverter component 110a is different from the pressure of the medium at the second outlet end of the second diverter component 110b, so that the atomized particle size of the first nozzle is different from the particle size atomized by the second nozzle.

[0203] In a specific application, the second flow diversion component 110b is provided with a second inlet and a plurality of second outlets. The medium enters the second flow diversion component 110b from the second inlet and flows out from the plurality of second outlets, thereby achieving a flow diversion effect on the medium.

[0204] When the second flow diversion component 110b is connected to the atomization component 120, the medium diverted by the second flow diversion component 110b is discharged from the second outlet and flows to the atomization component 120. The atomization component 120 can further atomize the medium, thereby improving the atomization effect of the medium.

[0205] It is understandable that the nozzle kit 100 may include a first flow diversion component 110a and a second flow diversion component 110b. When the medium of the same pressure is input, the pressure of the medium at the first outlet end of the first flow diversion component 110a is different from the pressure of the medium at the second outlet end of the second flow diversion component 110b, so that the first flow diversion component 110a and the second flow diversion component 110b have different diversion effects on the medium. Then, the medium after diversion by the first flow diversion component 110a and the second flow diversion component 110b is further atomized by the atomization component 120, and the atomized particle sizes of the obtained atomized medium are different.

[0206] In the embodiment of the present application, the first diverter component 110a and the second diverter component 110b are both detachably connected to the atomizing component 120. In this way, different diverter components 110 can be selected to be connected to the atomizing component 120 according to different application scenarios. Through the cooperation of the first diverter component 110a or the second diverter component 110b with the atomizing component 120, the medium can be further atomized after being diverted, and an atomized medium with a smaller particle size can be obtained, thereby improving the atomization effect of the nozzle kit 100.
