Furthermore, the terms "first," "second," and "third," etc., are used solely for distinction and should not be construed as indicating or implying relative importance.

[0051] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0052] This embodiment provides an unmanned device, which includes an unmanned device body and an atomizing mechanism 010 (such as Figure 1 As shown), the unmanned equipment body can drive the atomization mechanism 010 to move synchronously, and the atomization mechanism 010 is used to atomize and spray water, liquid fertilizer, etc.

[0053] It should be noted that the above-mentioned unmanned equipment bodies include but are not limited to drones, unmanned vehicles or robots, etc., and are not specifically limited here.

[0054] Please refer to Figure 1 and Figure 2 The atomizing mechanism 010 includes a driving mechanism 100 and a centrifugal spray disc 200. The centrifugal spray disc 200 includes a spray disc 210 and atomizing teeth 220 connected to the spray disc 210. The driving mechanism 100 is in driving connection with the spray disc 210 and is used to drive the spray disc 210 to rotate about its own rotation axis. When the driving mechanism 100 drives the spray disc 210 to rotate about its own rotation axis, the liquid flowing into the spray disc 210 will flow toward the periphery of the spray disc 210 under the action of centrifugal force. Under the action of the atomizing teeth 220, the liquid can be cut into small droplets, which are then sprayed out in an atomized manner.

[0055] Furthermore, the centrifugal spray disc 200 includes a plurality of atomizing teeth 220 connected to the spray disc 210. The plurality of atomizing teeth 220 are distributed adjacent to the outer periphery of the spray disc 210 and are spaced apart along the circumference of the spray disc 210. This arrangement facilitates efficient and reliable cutting of the liquid into small droplets using the plurality of atomizing teeth 220 to achieve atomization.

[0056] Further, please refer to Figure 3 and Figure 4 The atomizing mechanism 010 also includes a guide cover 300, which has a second liquid inlet 310, a diverter chamber 320, and a second liquid outlet 330. The second liquid inlet 310 and the second liquid outlet 330 are both connected to the diverter chamber 320; the driving mechanism 100 is connected to the spray disc 210 through the diverter chamber 320. The liquid to be atomized and sprayed can flow from the second liquid inlet 310 into the diverter chamber 320, and then flow to the spray disc 210 through the second liquid outlet 330, and then be atomized and sprayed out by the rotating centrifugal spray disc 200; wherein, after the liquid to be atomized and sprayed enters the diverter chamber 320, a certain diversion effect can be achieved first, which is conducive to making the liquid flow relatively evenly to the atomizing teeth 220, thereby ensuring the uniformity of the atomized spray. Moreover, arranging the guide cover 300 between the driving mechanism 100 and the spray disc 210 can ensure the compactness and stability of the structure.

[0057] Optionally, the connection methods of the atomizing teeth 220 and the spray disc 210 include but are not limited to integral molding, connection with fasteners such as bolts, and bonding.

[0058] Optionally, the deflector cover 300 is connected to the driving mechanism 100 , and the connection methods include but are not limited to connection with fasteners such as bolts and clamping.

[0059] Optionally, the driving mechanism 100 includes a motor, the guide cover 300 is connected to the motor, and the output shaft of the motor passes through the diversion cavity 320 and is transmission-connected to the spray disc 210 .

[0060] It should be understood that the output shaft of the motor can be directly connected to the spray disc 210, or the output shaft of the motor can be connected to the spray disc 210 through a transmission shaft, which is not specifically limited here.

[0061] In the related art, in order to ensure that the liquid to be atomized and sprayed can reliably flow to the atomizing teeth so that the atomizing teeth can cut the liquid into fine droplets, and in order to ensure that the driving mechanism can be reliably electrically connected to the control module of the unmanned equipment body, the atomizing teeth and the driving mechanism are both arranged on the upper surface of the spray disc; in this way, when the centrifugal spray disc rotates around its own rotation axis and atomizes and sprays the liquid, an upward fog field will be formed, and the water mist will easily adhere to the driving mechanism and the guide cover. Moreover, as the water mist accumulates on the guide cover and the driving mechanism, uncontrollable water droplets will form, and the accidental dripping of water droplets will easily lead to uneven atomization and spraying, resulting in poor atomization and spraying effect. In particular, in the embodiment where the unmanned equipment body is a propeller-type drone, the water mist generated by the atomization of the centrifugal spray disc is also easily lifted up under the action of the wind field provided by the propeller, and the water mist is more likely to adhere to the guide cover and the driving mechanism.

[0062] To improve the above problems, please refer to Figure 2 、 Figure 3 and Figure 5 The spray disc 210 of this embodiment has an assembly surface 211 and an atomizing surface 212 distributed opposite to each other. The spray disc 210 is transmission-connected to the driving mechanism 100, and the guide cover 300 and the driving mechanism 100 are both located on the side of the spray disc 210 where the assembly surface 211 is provided; the assembly surface 211 is provided with a first liquid inlet 213, and the second liquid outlet 330 of the guide cover 300 is connected to the first liquid inlet 213; the atomizing teeth 220 are connected to the atomizing surface 212. Since the driving mechanism 100 that is transmission-connected to the spray disc 210 and the atomizing teeth 220 for cutting the liquid are distributed on opposite sides, and the guide cover 300 is also distributed on opposite sides of the atomizing teeth 220, the spray disc 210 can be used to prevent the water mist formed on the atomizing surface 212 from flying to the assembly surface 211, and improve the problem of the water mist atomized on the atomizing surface 212 adhering to the driving mechanism 100 and the guide cover 300, and improve the problem of the water mist accumulating on the driving mechanism 100 and the guide cover 300 to form uncontrollable water droplets, thereby ensuring the reliability and uniformity of the atomization spraying.

[0063] Furthermore, the centrifugal spray disc 200 further includes a water retaining member 230, which is located on the side of the spray disc 210 provided with the atomizing surface 212 and is distributed opposite to the first liquid inlet 213; when the spray disc 210 rotates around its own rotation axis, the liquid transported from the first liquid inlet 213 to the water retaining member 230 is thrown toward the atomizing teeth 220 under the action of centrifugal force and cut into droplets by the atomizing teeth 220. Providing the water retaining member 230 at a position opposite to the first liquid inlet 213 can improve the problem that part of the liquid cannot be cut by the atomizing teeth 220 after flowing through the first liquid inlet 213 and directly drips due to the fact that the centrifugal rotation speed of the spray disc 210 is not fast enough or the liquid inlet speed from the first liquid inlet 213 is too fast, thereby further ensuring the uniformity and reliability of the atomized spray.

[0064] Furthermore, the water retaining member 230 includes a connecting member 231 and a water retaining plate 232. The water retaining plate 232 is connected to the atomizing surface 212 via the connecting member 231, and the water retaining plate 232 is distributed relative to the first liquid inlet 213. The connecting member 231 is provided with a first liquid outlet 233. When the spray disc 210 rotates around its own rotation axis, the liquid transported from the first liquid inlet 213 to the water retaining plate 232 is thrown toward the atomizing teeth 220 through the first liquid outlet 233 under the action of centrifugal force. Such a setting ensures that, on the one hand, the liquid transported from the first liquid inlet 213 to the spray disc 210 will not drip directly, and on the other hand, it ensures that the liquid transported from the first liquid inlet 213 to the spray disc 210 can reliably flow to the atomizing teeth 220, thereby ensuring the reliability of atomized spraying.

[0065] Optionally, the connection method between the water retaining plate 232 and the connecting member 231, and the connection method between the connecting member 231 and the spray plate 210 include but are not limited to integral molding, connection with fasteners such as bolts, and bonding.

[0066] To further improve the atomization effect, please refer to Figure 2 and Figure 5 The centrifugal spray disc 200 further includes cutting teeth 240, which are connected to the connecting member 231 and are distributed on the side of the first liquid outlet 233. When the spray disc 210 rotates around its own rotation axis, the liquid transported from the first liquid inlet 213 to the water retaining disc 232 is thrown to be cut by the cutting teeth 240 under the action of centrifugal force, and then thrown to the atomizing teeth 220 through the first liquid outlet 233. In this way, the cutting teeth 240 can be used to cut the liquid before it flows to the atomizing teeth 220 through the first liquid outlet 233, which is conducive to using the atomizing teeth 220 to cut the droplets that have already reduced in volume, so as to ensure that the atomizing teeth 220 cut a finer liquid, thereby ensuring a better atomization effect.

[0067] Furthermore, the connecting member 231 extends circumferentially around the first liquid inlet 213, forming a storage space connected to the first liquid inlet 213 between the connecting member 231 and the water retaining plate 232; the connecting member 231 is provided with a plurality of first liquid outlets 233, which are sequentially spaced around the first liquid inlet 213; the centrifugal spray disc 200 includes a plurality of cutting teeth 240, each of which is connected to the connecting member 231 and sequentially spaced around the first liquid inlet 213, with a first liquid outlet 233 between two adjacent cutting teeth 240. This arrangement enables, under the action of centrifugal force, liquid flowing into the water retaining plate 232 to evenly flow from the plurality of first liquid outlets 233 to the atomizing teeth 220, that is, liquid flowing from the first liquid inlet 213 to the storage space can be dispersed by the plurality of cutting teeth 240 and the plurality of first liquid outlets 233, thereby ensuring uniform atomized spraying.

[0068] It should be noted that the number of first liquid outlets 233 can be selected as needed, for example: 8, 10, 20, etc., and the number of cutting teeth 240 can also be selected as needed, for example: 8, 10, 20, etc., which are not listed here and are not specifically limited.

[0069] In this embodiment, please refer to Figure 6 The atomizing surface 212 is provided with an atomizing channel 260, which is connected to the first liquid outlet 233 and is used to guide the liquid to flow toward the atomizing teeth 220. Such a configuration can ensure the reliability of the liquid flowing toward the atomizing teeth 220, thereby ensuring the reliability of atomization.

[0070] Furthermore, the atomizing surface 212 is provided with a plurality of atomizing channels 260 , and the plurality of atomizing channels 260 are connected to the plurality of first liquid outlets 233 in a one-to-one correspondence; such a configuration can ensure the uniformity and reliability of atomizing spraying.

[0071] Furthermore, the centrifugal spray disc 200 further includes a plurality of partitions 270, and the plurality of partitions 270 are all connected to the atomizing surface 212, and the plurality of partitions 270 are spaced and distributed in sequence around the axis of rotation of the spray disc 210, one end of the partition 270 extends to the connecting member 231, and the other end extends to the periphery of the spray disc 210, and an atomizing channel 260 is formed between two adjacent partitions 270, and the atomizing channel 260 is relatively distributed with respect to the atomizing teeth 220. Such an arrangement can ensure that the liquid thrown out from the water retaining member 230 under the action of centrifugal force can flow in different atomizing channels 260 respectively without converging together, and also ensure that the liquid transported in the atomizing channel 260 can reliably flow to the atomizing teeth 220 and be cut into small droplets by the atomizing teeth 220, thereby ensuring the uniformity and reliability of the liquid dispersion atomization.

[0072] The shapes and distribution of the cutting teeth 240, the atomizing channel 260 and the partition 270 can be set as needed; please refer to Figure 6 and Figure 7 , among which, Figure 6 As shown, arrow a points to the direction of rotation of the centrifugal spray disc. In this embodiment, the length extension direction of the cutting tooth 240 is distributed at an acute angle to the radius of the water retaining disc 232, and the cutting tooth 240 has a first end 241 close to the rotation axis of the water retaining disc 232 and a second end 242 away from the rotation axis of the water retaining disc 232. Along the rotation direction of the water retaining disc 232 around its own axis, the first end 241 is located in front of the second end 242. When the spray disc 210 drives the water retaining disc 232 to rotate synchronously, the first end 241 of the cutting tooth 240 can first cut into the liquid flowing toward the water retaining disc 232, and as the cutting tooth 240 moves with the water retaining disc 232, the cutting tooth 240 can reliably insert into the liquid and separate the liquid, thereby ensuring the reliability of using the cutting tooth 240 to cut and disperse the liquid in advance.

[0073] It should be noted that the length extension direction of the cutting teeth 240 forms an acute angle with the radius of the water retaining plate 232 , specifically, the line connecting the first end 241 and the second end 242 forms an acute angle with the radius of the water retaining plate 232 .

[0074] Furthermore, the cutting tooth 240 has a first side 243 and a second side 244 disposed in opposite directions. In the direction of rotation of the water retaining plate 232 about its axis, the first side 243 is located in front of the second side 244, and the second side 244 is a circular convex surface. The width of the first end 241 is smaller than the width of the second end 242. This arrangement allows the first end 241 of the cutting tooth 240 to have a pointed shape, which helps ensure the reliability of the cutting tooth 240 in cutting and dispersing the liquid.

[0075] Optionally, the width of the cutting teeth 240 gradually increases from the first end 241 to the second end 242 ; such an arrangement can ensure the reliability of the cutting teeth 240 in cutting and dispersing the liquid.

[0076] Optionally, the angle α2 between the second side 244 of the cutting tooth 240 and the extension line of the radius of the water retaining plate 232 is greater than the angle α1 between the first side 243 of the cutting tooth 240 and the extension line of the radius of the water retaining plate 232. Such an arrangement can ensure that the liquid cut by the cutting tooth 240 reliably flows from the first liquid outlet 233 next to the second side 244 of the cutting tooth 240 to the corresponding atomization channel 260.

[0077] It should be noted that the angle α2 between the second side 244 of the cutting tooth 240 and the extension line of the radius of the water retaining plate 232 can specifically refer to: the angle between the tangent line of the connection between the second side 244 of the cutting tooth 240 and the connecting member 231 and the extension line of the radius of the water retaining plate 232.

[0078] It should also be noted that the angles of angle α2 and α1 can be set as needed. For example, the angle of angle α2 is 45°, 50°, 60°, etc., and the angle of angle α1 is 20°, 30°, 35°, etc., and no specific limitations are given here.

[0079] Please refer to Figure 6 In this embodiment, the width of the atomizing channel 260 gradually increases from the end closest to the rotation axis of the spray disc 210 to the end farther from the rotation axis of the spray disc 210. This configuration allows the liquid to gradually disperse as it flows through the atomizing channel 260 toward the atomizing teeth 220, thereby ensuring the reliability of the atomizing teeth 220 in cutting and dispersing the liquid.

[0080] Of course, in other embodiments, the width of the atomizing channel 260 may remain the same from one end close to the rotation axis of the spray disc 210 to one end away from the rotation axis of the spray disc 210 .

[0081] For further information, please refer to Figure 7 The separator 270 has a third end 271 located near the rotation axis of the spray disc 210 and a fourth end 272 located away from the rotation axis of the spray disc 210. The line connecting the third end 271 and the fourth end 272 forms an acute angle α3 with the radius of the spray disc 210. Along the rotation direction of the spray disc 210 about its axis, the third end 271 is located in front of the fourth end 272. This arrangement ensures that liquid entering the atomization channel 260 can flow smoothly within the atomization channel 260 when the spray disc 210 rotates about its axis.

[0082] Furthermore, the separator 270 has a third side 273 and a fourth side 274 disposed in opposite directions. Along the rotational direction of the spray disc 210 about its axis, the third side 273 is disposed in front of the fourth side 274. The third side 273 is a convex arc surface, while the fourth side 274 is a concave arc surface. This arrangement ensures that liquid entering the atomization channel 260 can flow smoothly within the atomization channel 260 when the spray disc 210 rotates about its axis, thereby ensuring reliable dispersion and atomization of the liquid by the centrifugal spray disc 200.

[0083] It should be noted that the acute angle α3 formed by the line connecting the third end 271 and the fourth end 272 and the radius of the spray disc 210 can be set as needed, for example: 30°, 40°, 50°, etc., which is not specifically limited here.

[0084] Optionally, the cutting teeth 240 are connected to the sidewall of the atomizing channel 260; specifically, the cutting teeth 240 are connected to the separator 270 via the connector 231, and a smooth transition is formed between the first side 243 of the cutting teeth 240, the inner wall of one side of the first liquid outlet 233, and the third side 273 of the separator 270, and a smooth transition is formed between the second side 244 of the cutting teeth 240, the inner wall of the other side of the first liquid outlet 233, and the fourth side 274 of the separator 270. This arrangement ensures that the liquid, after being cut by the cutting teeth 240, flows smoothly from the first liquid outlet 233 into the atomizing channel 260.

[0085] The distribution of the atomizing teeth 220 is similar to that of the related art; illustratively, the atomizing teeth 220 have a fifth end (not shown in the figure) close to the rotation axis of the spray disc 210 and a sixth end (not shown in the figure) away from the rotation axis of the spray disc 210. Along the rotation direction of the spray disc 210 around its own rotation axis, the fifth end is located in front of the sixth end, and the line connecting the fifth end and the sixth end forms an acute angle with the radius of the spray disc 210, and the angle includes but is not limited to 30°, 45°, 60°, etc., which is not specifically limited here.

[0086] The shape of the spray plate 210 can be selected as needed; please refer to Figure 4 In this embodiment, the atomizing surface 212 of the spray disc 210 is a concave surface. When the spray disc 210 rotates around its own axis, the liquid will not only be cut by the atomizing teeth 220 to form water mist, but the liquid will also collide with the atomizing surface 212 during the process of flowing toward the periphery of the spray disc 210 under the action of centrifugal force, thereby reducing the volume. The atomizing teeth 220 can then be used to cut the droplets with further reduced volume, thereby ensuring that the final atomized droplets are smaller and finer, further ensuring uniform and reliable atomization spraying.

[0087] Furthermore, the atomized surface 212 is a circular arc concave surface, the assembly surface 211 is a circular arc convex surface, and the atomized surface 212 and the assembly surface 211 are both approximately spherical surfaces.

[0088] Furthermore, the atomizing surface 212 is concave, and the slope of the generatrix of the atomizing surface 212 gradually increases along the radial direction of the spray disc 210 from one end close to the rotation axis of the spray disc 210 to one end away from the rotation axis of the spray disc 210, that is, the slope of the generatrix of the atomizing surface 212 gradually increases from the inside to the outside. Such an arrangement makes the atomizing surface 212 relatively flat at a position close to the rotation axis of the spray disc 210, and the slope of the atomizing surface 212 is larger at a position away from the rotation axis of the spray disc 210, which can ensure that the liquid thrown out from the water retaining member 230 can reliably flow toward the periphery of the spray disc 210, and can also ensure that the droplets cut by the atomizing teeth 220 connected to the spray disc 210 have a tendency to be thrown downward out of the spray disc 210 under the obstruction of the position of the atomizing surface 212 near the periphery. Therefore, while ensuring the reliability of the spray disc 210 in atomizing the liquid, the problem of the water mist flying toward the driving mechanism 100 is effectively improved.

[0089] Of course, in other embodiments, the spray plate 210 may also be roughly in the shape of a truncated cone.

[0090] Alternatively, please refer to Figure 8 In other embodiments, the spray disc 210 can also be a flat plate structure, and the atomizing surface 212 and the assembly surface 211 are both flat. When this type of spray disc 210 rotates around its own rotation axis, the resistance it encounters is smaller than the resistance of the assembly surface 211 being a circular arc convex surface. Therefore, when the rotation speed and liquid flow rate of the spray disc 210 with a flat assembly surface 211 and the spray disc 210 with a circular arc convex surface are equal, in the embodiment in which the assembly surface 211 is flat, the energy consumption of the driving mechanism 100 is smaller, and the energy consumption difference between the driving mechanisms 100 of the two can reach about 10%.

[0091] Please note that, please refer to Figure 9 and Figure 10 , the cross-sectional area of the mist field formed by the spray disc 210 with a flat atomizing surface 212 is larger than the cross-sectional area of the mist field formed by the spray disc 210 with a concave atomizing surface 212; specifically, when the diameter of the spray disc 210 with a flat atomizing surface 212 projected on a plane perpendicular to the rotation axis of the spray disc 210 is equal to the diameter of the spray disc 210 with a concave atomizing surface 212 projected on a plane perpendicular to the rotation axis of the spray disc 210, the spray disc 210 with a concave atomizing surface 212 is more likely to be atomized due to the liquid The liquid will be obstructed by the concave atomizing surface 212 and tend to spray downward, so the distance at which the liquid is sprayed along the diameter direction of the spray disc 210 is relatively close, thereby forming a fog field with a relatively small cross-section in the diameter direction of the spray disc 210. When the spray disc 210 has a flat atomizing surface 212, the liquid will not be obstructed by the atomizing surface 212 when atomizing and spraying. Therefore, the liquid can be sprayed farther along the diameter direction of the spray disc 210, thereby forming a fog field with a relatively large cross-section in the diameter direction of the spray disc 210.

[0092] In order to ensure that the liquid delivered to the water retaining plate 232 can reliably flow to be cut by the atomizing teeth 220 under the action of centrifugal force; Figure 11 The height of the outer edge of the spray disc 210 is lower than the height of the water retaining disc 232, that is, the height difference H between the outer edge of the spray disc 210 and the water retaining disc 232 is greater than 0, and in the extension direction of the rotation axis of the spray disc 210, the water retaining disc 232 is located between the first liquid inlet 213 and the outer edge of the spray disc 210. Because the atomizing surface 212 of the spray disc 210 is concave, the outer edge of the spray disc 210 is the lowest point of the spray disc 210 along the extension direction of the rotation axis of the spray disc 210. The height difference between the lowest point of the spray disc 210 and the water retaining disc 232 is greater than 0, so that the water retaining disc 232 is distributed between the lowest point and the highest point in the axial direction of the spray disc 210, thereby ensuring that liquid ejected from the water retaining disc 232 under the action of centrifugal force can reliably flow to the atomizing surface 212 and ensure that such liquid can be reliably cut by the atomizing teeth 220.

[0093] Of course, in other embodiments, the height of the outer edge of the spray disc 210 is equal to the height of the water retaining disc 232, that is, the height difference H between the outer edge of the spray disc 210 and the water retaining disc 232 is equal to 0, that is, along the axial direction of the spray disc 210, the lowest point of the spray disc 210 is flush with the water retaining disc 232.

[0094] It should be noted that the lowest point of the above-mentioned spray disc 210 refers to a relative position, not an absolute position. Specifically, the lowest point of the spray disc 210 refers to the lowest point of the spray disc 210 in the vertical direction when the rotation axis of the spray disc 210 extends in the vertical direction and the atomizing teeth 220 are distributed below the spray disc 210.

[0095] Please understand, please refer to Figure 8 In the embodiment where the atomizing surface 212 is a plane, along the axial direction of the spray disc 210, the atomizing surface 212 is distributed on the side of the water retaining plate 232 facing the driving mechanism 100, and the height difference H between the atomizing surface 212 and the water retaining plate 232 is greater than 0.

[0096] Please refer to Figure 3 and Figure 5 In this embodiment, the centrifugal spray disc 200 further includes an assembly 250 connected to the water retaining plate 232. The assembly 250 is configured for transmission connection with the drive mechanism 100 disposed through the first liquid inlet 213. Specifically, the motor output shaft passes through the diverter cavity 320 and is coaxially connected to the assembly 250. In other words, the motor output shaft is transmission-connected to the spray disc 210 via the assembly 250 and the water retaining plate 232. This arrangement ensures a reliable transmission connection between the motor and the spray disc 210.

[0097] The connection method between the assembly part 250 and the output shaft of the motor can be selected as needed. In this embodiment, the assembly part 250 is provided with an assembly hole 251. The output shaft of the motor is inserted into the assembly hole 251 from one end, and a fastener is inserted from the other end of the assembly hole 251 and connected to the output shaft of the motor. The fastener includes but is not limited to a bolt.

[0098] Of course, in other embodiments, the connection between the output shaft of the motor and the assembly part 250 may also be a snap connection or a threaded connection, etc., which is not specifically limited here.

[0099] Please refer to Figure 3 and Figure 12 In this embodiment, the flow guide cover 300 is connected to a flange 340, which is distributed around the outer circumference of the second liquid outlet 330. The flange 340 is used to guide the flow of liquid flowing out of the second liquid outlet 330. Under the guiding effect of the flange 340, it is possible to ensure that the liquid flowing out of the second liquid outlet 330 reliably flows into the receiving space through the first liquid outlet 233, thereby ensuring that the rotating centrifugal spray disc 200 can reliably atomize and spray the liquid from the atomizing surface 212, and it is not easy for the liquid to flow back to the assembly surface 211, thereby effectively improving the problem of water mist adhering to the flow guide cover 300 and the drive mechanism 100.

[0100] Furthermore, part of the guide cover 300 and the flange 340 are inserted into the first liquid inlet 213; such a setting can fully improve the problem of the liquid delivered to the spray disc 210 flowing back to the assembly surface 211, wherein, under the action of the flange 340, the problem of the liquid delivered to the spray disc 210 flowing from the gap between the guide cover 300 and the inner wall of the first liquid inlet 213 to the assembly surface 211 can be improved.

[0101] Alternatively, see Figure 12 The guide cover 300 includes a guide cover body 301 and an insert 302, one end of the insert 302 is connected to the guide cover body 301, and the other end of the insert 302 is provided with a second liquid outlet 330, and the flange 340 is connected to the end of the insert 302 away from the guide cover body 301, and surrounds the outer circumference of the insert 302; the guide cover body 301 is provided with a second liquid inlet 310 and a diversion cavity 320; the insert 302 and the flange 340 are inserted into the first liquid inlet 213, and the flange 340 can prevent the liquid delivered to the spray disc 210 from flowing from the gap between the inner wall of the first liquid inlet 213 and the insert 302 to the assembly surface 211.

[0102] It should be noted that, by setting the flange 340, the liquid delivered to the spray disc 210 is effectively prevented from flowing toward the assembly surface 211, so that the atomizing mechanism 010 has a wider range of uses when in use, that is, in addition to configuring the spray disc 210 to be located below the driving mechanism 100 and extending the rotation axis of the spray disc 210 in the vertical direction, the entire atomizing mechanism 010 can also be set horizontally, that is, the rotation axis of the spray disc 210 extends horizontally, and the atomizing mechanism 010 can even be set as a whole at an angle, that is, the driving mechanism 100 is located obliquely below the spray disc 210, and the rotation axis of the spray disc 210 is distributed at an angle.

[0103] Alternatively, see Figure 12 The guide cover body 301 is provided with a first flow channel 311 and a second flow channel 312 that are connected to each other and arranged at an angle. The end of the first flow channel away from the second flow channel 312 is connected to the second liquid inlet 310, and the end of the second flow channel 312 away from the first flow channel 311 is connected to the diversion cavity 320. This arrangement can achieve the purpose of slowing down the flow at the corner connection between the first flow channel 311 and the second flow channel 312, thereby improving the problem of liquid entering the diversion cavity 320 too quickly.

[0104] The included angle between the first flow channel 311 and the second flow channel 312 can be selected as needed, for example, 90°, 80°, 100°, etc., which is not specifically limited here.

[0105] The atomizing mechanism 010 of this embodiment can be used for atomization and spraying. When in use, the sprayed liquid is transported to the spray disc 210 through the guide cover 300, and the driving mechanism 100 is used to drive the spray disc 210 to rotate around its own axis, so that the liquid flowing to the water retaining member 230 through the first liquid inlet 213 can flow to the atomizing teeth 220 under the action of centrifugal force, and the liquid is cut into small droplets under the action of the atomizing teeth 220.

[0106] In summary, the atomizing mechanism 010 of the present invention can be used in unmanned equipment, and the centrifugal spray disc 200 of the atomizing mechanism 010 can improve the problem of atomized water mist adhering to the driving mechanism 100, thereby ensuring the reliability of atomizing spraying.

[0107] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
