Referring to fig. 1, the present embodiment provides an atomization apparatus 1000, and correspondingly, an unmanned device (not shown). The robot includes a robot body (not shown) and the atomizing device 1000, and the atomizing device 1000 is mounted on the robot body. The atomization device 1000 can atomize liquid, and the atomization device 1000 can perform spraying operation in the operation process of the unmanned equipment body. The unmanned aerial vehicle body can be unmanned aerial vehicle, unmanned car, unmanned ship etc..

Specifically, referring to fig. 1, the atomization device 1000 includes a driving motor 200, a liquid inlet pipe 300, and a centrifugal spray disk 100; the output shaft of the driving motor 200 is connected with the centrifugal spray disk 100 and is used for driving the centrifugal spray disk 100 to rotate, and the liquid inlet pipe 300 is connected with the shell of the driving motor 200 and is used for feeding liquid into the centrifugal spray disk 100. The housing of the drive motor 200 is mounted on the main body of the unmanned device. When the atomization device 1000 works, liquid to be atomized flows into the centrifugal spray disk 100 through the liquid inlet pipe 300, the centrifugal spray disk 100 rotates around the axis of the centrifugal spray disk 100 under the driving of the driving motor 200, and the liquid flowing into the centrifugal spray disk 100 is centrifugally sprayed out.

In this embodiment, improve traditional centrifugation dish of spouting for it can still realize the more even effect of liquid droplet atomizing when low-speed (for example, 2000 rpm) operation, and the application of product is more extensive like this, and, because the low-speed atomizing effect that can realize the preferred, can improve driving motor 200's life greatly. Meanwhile, it should be noted that, when the liquid inlet flow rate of the liquid inlet pipe 300 is relatively large, the overall atomization effect is more obvious. The centrifugal nozzle plate 100 provided in the present embodiment will be described in detail below.

Referring to fig. 2 to 5, fig. 2 shows a first centrifugal spray disk 100 provided in this embodiment, which includes a disk-shaped bottom plate 10 and a plurality of teeth 20.

Specifically, the chassis 10 has a central portion 11 and an upper surface 12, and the upper surface 12 is formed with a blank area 13 surrounding the central portion 11 and a cutting area 14 surrounding the blank area 13 and directly adjacent to the blank area. The blank region 13 is adapted to receive fluid and to allow fluid to flow into the cutting region 14 when the base plate 10 is rotated. It should be noted that the central portion 11 may be provided with a mounting hole 111 for mounting an output shaft of the driving motor 200. The center portion 11 is located at the center of the chassis 10, and it is understood that the center of the chassis 10 is located on the center portion 11. On the upper surface 12, division is performed, a portion near the central portion 11 of the chassis 10 is a blank area 13, a portion near the peripheral edge 15 of the chassis 10 is a cut area 14, and the blank area 13 is directly adjacent to the cut area 14, in other words, the outer periphery of the blank area 13 is the inner periphery of the cut area 14. As illustrated in the relative position in fig. 2, the area between the outer periphery of the central portion 11 and the first preset circle 101 (shown by the dotted line) is the blank area 13, and the area between the first preset circle 101 and the second preset circle 102 (shown by the dotted line) is the cutting area 14.

A plurality of teeth 20 are positioned in the cutting area 14, the plurality of teeth 20 are convexly arranged on the upper surface 12, the plurality of teeth 20 are arranged along the circumferential direction of the chassis 10, the teeth 20 are used for cutting the liquid centrifugally flowing from the blank area 13, and an atomizing flow channel 30 for flowing the cut liquid is formed between two adjacent teeth 20. It should be noted that the ends of all the teeth 20 close to the central portion 11 are located on the circumference of the first predetermined circle 101, and the ends of all the teeth 20 far from the central portion 11 are located on the circumference of the second predetermined circle 102. The void area 13 is understood to mean that there is substantially no structure above the upper surface 12 in this position that would block the flow of liquid nor would it direct the flow of liquid. After the liquid in the liquid inlet pipe 300 is discharged, it directly falls to the vicinity of the outer periphery of the center portion 11. And it flows towards the peripheral edge 15 of the chassis 10 in a substantially free divergent condition (radially around the central portion 11), in other words, the liquid flows directly into the cutting zone 14 in a free divergent condition under the action of the centrifugal force, directly cut by the teeth 20, after falling from the periphery of the central portion 11.

In this embodiment, referring to fig. 2 and 4, the chassis 10 further includes a lower surface 17, the centrifugal spray disk 100 further includes a fixing column 18 and at least one reinforcing rib 19, the fixing column 18 is protruded on the lower surface 17, and the reinforcing rib 19 is connected to both the lower surface 17 and the fixing column 18. This strengthening rib 19 can increase the structural strength of whole structure, can increase of service life, simultaneously, during concrete implementation, the quantity of strengthening rib 19 can be one, also can be two, three, four etc. generally, when the quantity of strengthening rib 19 is two, its can symmetric distribution in the both sides of fixed column 18, be "one" style of calligraphy and distribute, when the quantity of strengthening rib 19 is four, it can evenly distributed around fixed column 18, be "ten" style of calligraphy and distribute. In one implementation, the chassis 10, the fixing posts 18, and the reinforcing ribs 19 are integrally formed.

In the present embodiment, referring to fig. 2 and 4, the mounting hole 111 provided in the center portion 11 is used for mounting the output shaft of the driving motor 200, and the mounting hole 111 extends to the inside of the fixing post 18. Like this, increased the installation depth of this driving motor 200's output shaft, further promoted installation stability, simultaneously, owing to have strengthening rib 19, can improve the stability of whole operation greatly.

The extending direction of the teeth 20 forms an included angle a with the radial direction of the chassis 10, the tooth height of the teeth 20 is b, and the tooth distance corresponding to two adjacent teeth 20 is c.

Wherein, the included angle that at least some tooth 20 correspond satisfies: a is more than or equal to 0 degree and less than or equal to 5 degrees. For example, in the specific implementation, a may be selected from 0 °, 1 °, 2 °, 3 °, 4 °, 5 °, and the like.

The tooth height of at least part of the teeth 20 satisfies: b is more than 0mm and less than or equal to 5 mm. For example, in the specific embodiment, b may be selected from 1mm, 2mm, 3mm, 4mm, 5mm, and the like.

At least part of the teeth 20 correspond to teeth with a pitch satisfying: c is more than or equal to 1mm and less than or equal to 5 mm. For example, in the specific implementation, c can be selected from 1mm, 2mm, 3mm, 4mm and 5 mm.

It should be noted that, when the shape of the tooth 20 is a rectangle, the extending direction thereof is the length direction thereof, and when the shape of the tooth 20 is an isosceles triangle, the extending direction thereof is the angular bisector direction of the vertex angle thereof, and so on. When the included angle a is equal to 0 °, it is understood that the tooth 20 extends along the radial direction of the chassis 10, and when the included angle a is equal to 0 °, it is understood that the tooth 20 is disposed obliquely along the radial direction of the chassis 10, for example, in the centrifugal spray disk 100 in the view of fig. 2, the tooth 20 is equivalent to being rotated counterclockwise or clockwise by a certain angle based on the center of mass of the tooth as the center of the tooth, so that the tooth 20 is finally inclined with respect to the radial direction of the center. For example, if the tooth 20 is rotated clockwise by a certain angle, the angle a is positive, and if the tooth 20 is rotated counterclockwise by a certain angle, the angle a is negative, and the above-mentioned angle a refers to an absolute value, in other words, the angle a can be understood to satisfy: a is more than or equal to minus 5 degrees and less than or equal to 5 degrees. In this way, when it is determined that the driving motor 200 drives the centrifugal spray disk 100 to rotate clockwise or counterclockwise, the corresponding centrifugal spray disk 100 may be selected. In the present embodiment, as can be seen from the enlarged partial view on the upper left corner of fig. 2, three teeth 20 are shown in the enlarged partial view, wherein the middle tooth 20 is rotated counterclockwise by an angle a with the center of mass thereof on the basis of extending along the radial direction of the chassis 10, and finally the tooth 20 is inclined with respect to the radial direction of the chassis 10.

It should be noted that the tooth height b may be understood as a height of the tooth 20 protruding from the upper surface 12, and may also be understood as a distance between an end of the tooth 20 away from the upper surface 12 and the upper surface 12. The tooth spacing c is understood to mean the minimum distance between two adjacent teeth 20, and also the width of the atomization flow path 30.

The central part 11 of the chassis 10 is connected with the output shaft of the driving motor 200, the chassis 10 rotates under the driving of the driving motor 200, the liquid to be atomized above the chassis 10 is input on the chassis 10 and then enters the blank area 13 on the chassis 10, under the centrifugal action, the liquid directly flows into the cutting area 14, and the plurality of teeth 20 in the cutting area 14 simultaneously cut the liquid flowing into the cutting area 14 to atomize the liquid. Because the parameters of the tooth 20 are reasonably designed, for example, the extending direction of the tooth 20 forms an included angle a with the radial direction of the chassis 10, and the included angle corresponding to at least part of the tooth 20 satisfies: a is more than or equal to 0 degree and less than or equal to 5 degrees. The tooth height of at least part of the teeth 20 satisfies: b is more than 0mm and less than or equal to 5 mm. At least part of the teeth 20 correspond to teeth with a pitch satisfying: c is more than or equal to 1mm and less than or equal to 5 mm. Thus, when the centrifugal spray disk 100 operates in the low-speed mode, effective cutting and atomization of the liquid to be atomized can still be achieved, and thus the service life of the driving motor 200 is greatly prolonged.

Optionally, the included angle corresponding to at least some of the teeth 20 satisfies: a is more than or equal to 1.5 degrees and less than or equal to 2.5 degrees. And/or the presence of a gas in the gas,

the tooth height of at least part of the teeth 20 satisfies: b is more than 1.5mm and less than or equal to 3 mm. And/or the presence of a gas in the gas,

at least part of the teeth 20 correspond to teeth with a pitch satisfying: c is more than or equal to 1.5mm and less than or equal to 2 mm.

For example, in specific implementation, the included angle a may be selected from 1.5 °, 1.8 °, 2.3 °, 2.5 °, and the like. The tooth height b can be selected from 1.5mm, 1.8mm, 2.3mm, 2.5mm, 2.8mm, 3mm and the like. The tooth spacing c can be selected from 1.5mm, 1.8mm, 2mm and the like.

Optionally, in the same chassis 10, the included angle corresponding to the partial teeth 20 satisfies: a is more than or equal to 2 degrees and less than or equal to 3 degrees. The included angle corresponding to part of the teeth 20 satisfies: a is more than or equal to 1 degree and less than 2 degrees. The included angle corresponding to part of the teeth 20 satisfies: a is more than or equal to 0 degree and less than 1 degree.

In other words, different teeth 20 on the same chassis 10 have different inclination angles with respect to the radial direction of the chassis 10, some teeth 20 have larger inclination angles with respect to the radial direction of the chassis 10, and some teeth 20 have smaller inclination angles with respect to the radial direction of the chassis 10. For example, in the same chassis 10, the included angle a corresponding to some teeth 20 is 0 °, the included angle a corresponding to some teeth 20 is 0.5 °, the included angle a corresponding to some teeth 20 is 1 °, the included angle a corresponding to some teeth 20 is 1.5 °, the included angle a corresponding to some teeth 20 is 2 °, the included angle a corresponding to some teeth 20 is 2.5 °, and the included angle a corresponding to some teeth 20 is 3 °. It should be noted that, alternatively, the number of the teeth 20 corresponding to a certain included angle a on the chassis 10 is only one, and the number of the teeth 20 corresponding to a certain included angle a on the chassis 10 may also be multiple.

Optionally, the included angle corresponding to 50% of the teeth 20 in the plurality of teeth 20 satisfies: a is 2.5 °. The included angle a of 1.5 ° is satisfied for 30% of the plurality of teeth 20. The included angle a is 0 ° for 20% of the plurality of teeth 20.

It can be understood that, on the same chassis 10, half of the teeth 20 have an included angle a of 2.5 °, the rest of the teeth 20 have an included angle a of 1.5 °, and the rest of the teeth have an included angle a of 0 °. In other words, the chassis 10 has only three different inclined teeth 20. It should be noted that the distribution of the teeth 20 in the three different inclined states may be continuous, for example, when the number of the teeth 20 is 100, in the circumferential direction of the chassis 10, the included angle a corresponding to 50 consecutive teeth 20 is 2.5 °, the included angle a corresponding to 30 consecutive teeth 20 is 1.5 °, and the included angle a corresponding to 20 consecutive teeth 20 is 0 °. Of course, it may be random, i.e., the teeth 20 may be randomly distributed and irregular. The examples are merely examples, and in practical implementation, the teeth 20 are arranged in a distributed manner according to actual requirements.

The center of the chassis 10 is located at the center 11, and the connecting line between the center of mass of the teeth 20 and the center of the chassis 10 is in the radial direction of the chassis 10.

As can be understood from fig. 3, in two adjacent teeth 20, the tooth tips 22 of the two teeth 20 define the inlet 31 of the atomizing flow channel 30 therebetween, and the ends of the tooth bodies 21 of the two teeth 20 away from the tooth tips 22 define the outlet 32 of the atomizing flow channel 30 therebetween. The tip 22 of the tooth 20 cuts the liquid and the cut droplets enter the atomizing flow channel 30 and exit through the outlet 32 thereof.

The direction indicated by the arrow in fig. 3 is the direction of flow of the liquid.

Referring to fig. 3, the periphery 15 of the chassis 10 is provided with a saw tooth structure 16. And, the tooth bodies 21 of the teeth 20 are arranged adjacent to the peripheral edge 15 of the base plate 10, so that the outlet 32 of the atomizing flow passage 30 is defined by the tooth bodies 21 of two adjacent teeth 20 and the peripheral edge 15 of the base plate 10, and the liquid sprayed from the outlet 32 of the atomizing flow passage 30 can be cut by the sawtooth structures 16, thereby further improving the atomization effect of the liquid drops.

In one mode, the sawtooth structure 16 comprises a plurality of sawteeth protruding from the periphery 15 of the chassis 10 in the radial direction of the chassis 10. The plurality of serrations are evenly distributed around the circumference of the chassis 10. The serrations may be formed by providing a groove extending through the thickness direction (axial direction) of the chassis 10 at the peripheral edge 15 of the chassis 10, so that the serrations are formed such that the groove is defined between adjacent two serrations.

Referring to fig. 5, in the present embodiment, the upper surface 12 is a plane, the tooth body 21 is a trapezoid, the bottom surface 212 of the tooth body 21 is connected to the upper surface 12, the left side surface 213 of the tooth body 21 is parallel to the right side surface 214, the front side surface 215 of the tooth body 21 is parallel to the rear side surface 216, the left side surface 213, the right side surface 214, the front side surface 215, and the rear side surface 216 of the tooth body 21 are perpendicular to the bottom surface 212, and the top surface 211 and the bottom surface 212 of the tooth body 21 are inclined.

The tooth tip portion 22 is a triangular prism, a tooth tip bottom surface 222 of the tooth tip portion 22 is connected with the upper surface 12, a tooth tip top surface 221 of the tooth tip portion 22 is parallel to the tooth tip bottom surface 222, the tooth tip top surface 221 of the tooth tip portion 22 is connected with the top surface 211 of the tooth body 21, one tooth tip side surface 223 of the tooth tip portion 22 is attached to the right side surface 214 of the tooth body 21, and the other two tooth tip side surfaces 223 of the tooth tip portion 22 are respectively connected with the front side surface 215 and the rear side surface 216 of the tooth body 21.

The projection of the junction of the two remaining tooth tip flanks 223 of the tooth tip 22 on the upper surface 12 is a first point, the projection of the center of mass of the tooth 20 on the upper surface 12 is a second point, and the direction of the line connecting the first point and the second point defines the direction of extension of the tooth 20.

The distance between the tip top surface 221 and the tip bottom surface 222 of the tooth tip 22 defines the tooth height of the tooth 20.

The minimum distance between the two tip flanks 223 corresponding to the tips 22 of two adjacent teeth 20 defines the tooth pitch corresponding to the teeth 20.

In combination with the above, it will be appreciated that the teeth 20 may be generally configured as a combination of a trapezoidal body and a triangular prism. Referring to fig. 3, the projection of the tooth body 21 on the upper surface 12 is substantially rectangular, and the projection of the tooth tip 22 on the upper surface 12 is substantially isosceles triangle.

In connection with fig. 3, the sharpness of the point 22 can be defined by an angle m, which can be understood as the angle between two of the point flanks 223 of the spike. The angle m satisfies: m is 30 DEG-60 DEG, for example, 30 DEG, 45 DEG, 55 DEG, 60 deg.

Optionally, the tooth body 21, tooth tip 22 and chassis 10 are integrally formed. For example, the teeth 20 and the chassis 10 may be integrally formed by a mold. In other embodiments, the teeth 20 themselves may be integrally formed and fixed to the chassis 10 by welding.

Alternatively, all the teeth 20 have the same included angle in the same chassis 10. And/or all of the teeth 20 have the same tooth height. And/or all of the teeth 20 may have the same tooth spacing.

In other words, when the included angle a, the tooth height b and the tooth distance c of all the teeth 20 in the same chassis 10 are the same, the structural parameters of all the teeth 20 on the chassis 10 are the same, so that the distribution of all the teeth 20 on the chassis 10 is more regular.

Referring to FIG. 3, in the present embodiment, the length of the teeth 20 along the extending direction of the teeth 20 is d, and d is greater than or equal to 20mm and less than or equal to 30 mm. For example, the length d of the teeth 20 can be selected to be 20mm, 25mm, 30mm, etc.

Referring to FIG. 2, in the embodiment, the diameter of the chassis 10 is e, and e is greater than or equal to 300mm and less than or equal to 400 mm. For example, the diameter e of the chassis 10 can be selected from 300mm, 350mm, 400mm, etc. Of course, the chassis 10 is not limited to this range, and may be larger than 400mm in other embodiments. Such as 500mm, 600mm, etc.

Referring to fig. 2, in the present embodiment, the blank area 13 is circular, and the corresponding width of the blank area 13 is f 1.

The cutting area 14 is circular and the corresponding width f2 of the cutting area 14.

It is understood that the radius difference between the first preset circle 101 and the central portion 11 is f1, and the radius difference between the second preset circle 102 and the first preset circle 101 is f 2. The ratio k can be selected from 10, 15, 30, etc. The cutting zone 14 is located immediately peripherally adjacent to the sawtooth structure 16, in other words the cutting zone 14 is located in the area immediately adjacent to the periphery 15 of the chassis 10.

Referring to fig. 6 to 8, fig. 6 to 8 show a second centrifugal nozzle plate 100 provided in the present embodiment, which is basically the same as the first centrifugal nozzle plate 100, except that:

all the teeth 20 of the first centrifugal nozzle disk 100 shown in fig. 2 are distributed in a single toothing, i.e. only one toothing is included. All the teeth 20 of the second centrifugal nozzle plate 100 shown in fig. 6 are distributed in a multi-toothed ring, which in particular comprises two toothed rings. It should be noted that each ring gear comprises a plurality of teeth 20. In addition, in other embodiments, the number of the ring gears is not limited, and all the teeth 20 may be distributed in at least two ring gears, for example, three ring gears, four ring gears, and the like.

Typically, all of the ring gears are concentrically arranged. For example, referring to fig. 6, the two ring gears are an inner ring gear and an outer ring gear, respectively, and the plurality of teeth 20 included in the inner ring gear are distributed along a third preset circle 103 (shown by dotted lines), specifically, one end of the plurality of teeth 20 included in the inner ring gear near the center portion 11 is distributed on the circumference of the third preset circle 103. The plurality of teeth 20 comprised in the outer ring gear are distributed along a fourth predetermined circle 104 (shown by dashed lines), in particular the end of the plurality of teeth 20 comprised in the outer ring gear remote from the central portion 11 is distributed on the circumference of the fourth predetermined circle 104.

In other words, the area between the outer periphery of the central portion 11 and the third preset circle 103 forms the blank area 13, and the area between the third preset circle 103 and the fourth preset circle 104 forms the cutting area 14.

After the liquid flows into the centrifugal spray disk 100 from the liquid inlet pipe 300, the liquid firstly enters the blank area 13 and then flows to the cutting area 14 under the centrifugal action, the liquid is firstly cut into relatively atomized liquid drops by the plurality of teeth 20 in the inner gear ring, then flows to the outer gear ring under the centrifugal action, the liquid drops are cut by the plurality of teeth 20 in the outer gear ring and finally sprayed out from the peripheral edge 15 of the chassis 10, and the overall atomization effect is better.

Optionally, each ring gear comprises a plurality of atomizing flow passages 30, and the atomizing flow passages 30 in two adjacent ring gears are correspondingly communicated along the radial direction of the chassis 10. For example, in the present embodiment, the atomizing runners 30 in the inner ring gear and the atomizing runners 30 in the outer ring gear are all in one-to-one correspondence and are correspondingly communicated along the radial direction of the chassis 10, so that the droplets flowing into the atomizing runners 30 of the inner ring gear can smoothly enter the atomizing runners 30 of the outer ring gear, and thus, under the centrifugal action, the acceleration effect can be further realized, and the atomizing effect is improved.

Alternatively, in the outermost ring gear, the end of two adjacent teeth 20 near the peripheral edge 15 of the base plate 10 and the peripheral edge 15 of the base plate 10 together define the outlet 32 of the atomizing flow path 30. For example, in the present embodiment, the outlet 32 of the atomizing flow channel 30 is defined between the tooth bodies 21 of two adjacent teeth 20 in the outer ring gear and the peripheral edge 15 of the chassis 10, that is, the liquid droplets ejected from the atomizing flow channel 30 in the outer ring gear are directly ejected from the peripheral edge 15 of the chassis 10, and under the action of gravity, the liquid droplets can also be ejected after directly contacting with the peripheral edge 15 of the chassis 10, and after the peripheral edge 15 of the chassis 10 is provided with the sawtooth structures 16, the liquid droplets can directly contact with the sawtooth structures 16 and are further cut and atomized by the sawtooth structures 16, so that the atomizing effect can be improved to a certain extent.

According to the atomizing device 1000 provided in this embodiment, the operating principle of the atomizing device 1000 is as follows:

when the driving motor 200 is started, the centrifugal spraying disc 100 is driven to rotate, and after the liquid inlet pipe 300 enters liquid, the liquid is input above the centrifugal spraying disc 100, so that the liquid falls into the blank area 13 of the base disc 10.

Taking the centrifugal spray disk 100 in fig. 2 as an example, during the rotation of the chassis 10, the liquid falling into the blank area 13 directly flows to the cutting area 14 in a freely diverging manner under the action of the centrifugal force, and after being cut by the teeth 20 in the cutting area 14, the liquid flows out from the atomizing flow channel 30 between two adjacent teeth 20, and further, can be continuously cut by the sawtooth structures 16 on the peripheral edge 15 of the chassis 10, and finally is sprayed out from the peripheral edge 15 of the chassis 10 under the action of the centrifugal force and the gravity.

Taking the centrifugal spray disk 100 in fig. 6 as an example, during the rotation of the chassis 10, the liquid falling into the blank area 13 directly flows to the cutting area 14 in a freely diverging manner under the action of the centrifugal force, and after being cut by the teeth 20 in the inner ring gear in the cutting area 14, the liquid flows out from the atomizing flow channel 30 between two adjacent teeth 20 in the inner ring gear, then enters the outer ring gear, and after being cut by the teeth 20 in the outer ring gear, the liquid flows out from the atomizing flow channel 30 between two adjacent teeth 20 in the outer ring gear, further, the liquid can be continuously cut by the sawtooth structures 16 on the peripheral edge 15 of the chassis 10, and finally, the liquid is sprayed out from the peripheral edge 15 of the chassis 10 under the action of the centrifugal force and the gravity.

Referring to the relative position in fig. 1, when liquid flows from the liquid inlet pipe 300 to the centrifugal spray tray 100, the flow direction is vertical, the rotation axis of the base tray 10 is vertical, and after the liquid flows into the base tray 10, during the rotation of the base tray 10, due to the centrifugal effect, the speed direction of the liquid has a certain deviation angle with the radial direction of the base tray 10 during the liquid flows from the central portion 11 to the peripheral portion 15 of the base tray 10, therefore, the teeth 20 are obliquely arranged, so that the extending direction of the teeth 20 forms an included angle a with the radial direction of the base tray 10, and the teeth can be better cut and atomized along the flow direction of the liquid. Meanwhile, the height of the teeth 20 cannot be too high, when the height of the teeth 20 is too high, liquid is easy to float upwards after being cut by the teeth 20 and is easy to hit other fixing parts such as the driving motor 200, and certainly, the height of the teeth 20 cannot be too low, and when the height of the teeth 20 is too low, the liquid cannot be effectively cut. Meanwhile, the distance between the teeth 20 cannot be too large or too small, the too large atomization is incomplete, and the too small liquid is easy to accumulate and cannot be completely atomized.

By reasonably setting the included angle a, the tooth height b and the tooth distance c, the liquid can be sufficiently atomized at a low rotating speed of the centrifugal spray disk 100. Of course, when the flow rate, the type, etc. of the liquid are different, the included angle a, the tooth height b, and the tooth distance c are selected correspondingly.

For the technical scheme provided by this embodiment, due to the adoption of the above parameter design, the centrifugal spray disk 100 can still realize effective cutting and atomization of the liquid to be atomized under low-speed rotation, and the particle size of the liquid drops after cutting and atomization is almost the same as that of the liquid drops after high-speed cutting and atomization in the conventional technical means, so that the use cost can be greatly reduced by the application of the structure. Of course, the centrifugal spray disk 100 provided in this embodiment is not limited to be operated only in the low-speed mode, and when the flow rate of the liquid is large and the type of the liquid is different, the centrifugal spray disk 100 may be operated in the medium-speed mode or the high-speed mode.

To sum up, the embodiment of the utility model provides a dish 100, atomizing device 1000 and unmanned aerial vehicle are spouted in centrifugation, the central part 11 on chassis 10 and driving motor 200's output shaft, under driving motor 200's drive, chassis 10 is rotatory, be located the chassis 10 top treat the back on the atomizing liquid input chassis 10, advance in the blank 13 on the chassis 10, under centrifugal action, liquid directly flows into cutting area 14 in, a plurality of teeth 20 in the cutting area 14 are simultaneously to the liquid that flows into in cutting area 14 cutting, make its atomizing. Thus, when the centrifugal spray disk 100 operates in the low-speed mode, effective cutting and atomization of the liquid to be atomized can still be achieved, and thus the service life of the driving motor 200 is greatly prolonged.
