Referring to fig. 1, the present embodiment provides a spraying assembly 1000, and correspondingly, an unmanned device (not shown). The drone includes a drone body (not shown) and the spray assembly 1000, the spray assembly 1000 being mounted on the drone body. The spraying assembly 1000 can atomize the liquid to be atomized, and the spraying assembly 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 spray assembly 1000 includes a motor 200, a liquid inlet pipe 300, and a spray tray 100; an output shaft of the motor 200 is connected to the spray tray 100 and is used to drive the spray tray 100 to rotate, and the liquid inlet pipe 300 is connected to a housing of the motor 200 and is used to feed liquid to the spray tray 100. The housing of the motor 200 is mounted on the main body of the unmanned device. When the spraying assembly 1000 works, liquid to be atomized flows into the spraying tray 100 through the liquid inlet pipe 300, the spraying tray 100 rotates around the axis of the spraying tray 100 under the driving of the motor 200, and the liquid flowing into the spraying tray 100 is centrifugally sprayed out.

In this embodiment, improve traditional spray plate for it all can realize treating the effective cutting atomizing of atomizing liquid under different rotational speeds, and the homoenergetic reaches better atomization effect under different rotational speeds, and like this, the application of product is more extensive. The spray disk 100 provided in the present embodiment will be described in detail below.

Referring to fig. 2 to 5, fig. 2 to 5 show a first spray plate 100 provided in the present embodiment, which includes a disc body 10 in a disc shape and a plurality of cutting strips 20.

Specifically, the tray 10 includes a central portion 11 and a receiving surface 12, and the receiving surface 12 has 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 zone 14 as the disc 10 rotates. It should be noted that the central portion 11 may be provided with a mounting hole for mounting the output shaft of the motor 200. The central portion 11 is located at the center of the disk 10, and it will be appreciated that the center of the disk 10 is located on the central portion 11. The receiving surface 12 is divided into a blank area 13 near the center 11 of the tray 10, a cutting area 14 near the periphery 15 of the tray 10, and the blank area 13 is directly adjacent to the cutting area 14, i.e., the outer periphery of the blank area 13 is the inner periphery of the cutting area 14. As illustrated in the relative position in fig. 4, 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.

The plurality of cutting strips 20 are located in the cutting area 14, the plurality of cutting strips 20 are convexly arranged on the bearing surface 12, the plurality of cutting strips 20 are arranged along the circumferential direction of the tray body 10, the cutting strips 20 are used for cutting liquid which centrifugally flows in from the blank area 13, and a flow channel 30 for the flow of the cut liquid is formed between every two adjacent cutting strips 20. It should be noted that one end of each cutting strip 20 close to the central portion 11 is located on the circumference of the first predetermined circle 101, and one end of each cutting strip 20 far from the central portion 11 is located on the circumference of the second predetermined circle 102. The void area 13 is to be understood as meaning that there is substantially no structure above the receiving surface 12 in this position which blocks the flow of liquid and which guides 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 tray 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, after falling from the periphery of the central portion 11, and is directly cut by the cutting strips 20.

The cutting strips 20 extend at an angle a with respect to the radial direction of the disc body 10. In the same tray 10, all the cutting strips 20 have the following included angles: a is more than or equal to 0 degree and less than or equal to 10 degrees. Preferably, all the cutting strips 20 have corresponding included angles that satisfy: a is more than or equal to 0 degree and less than or equal to 5 degrees. For example, in specific implementation, a may be selected from 0 °, 1 °, 1.5 °, 2 °, 2.5 °, 3 °, 3.5 °, 4 °, 4.5 °, 5 °, 5.5 °, 6 °, 6.5 °, 7 °, 7.5 °, 8 °, 8.5 °, 9 °, 9.5 °, 10 °, and the like. When a > 0 °, it is understood that the extending direction of the cutting strand 20 is inclined to the radial direction of the disk 10, and when a is 0 °, it is understood that the extending direction of the cutting strand 20 coincides with the radial direction of the disk 10.

Also, among all the cut strips 20, there are at least two kinds of cut strips 20 having different included angles. In other words, in the same tray 10, there are two different included angles of the cutting string 20, for example, there are cases where a is 1 ° and a is 2 °, for example, there are cases where a is 2 ° and a is 4 °, etc., there are also three different included angles of the cutting string 20, for example, there are cases where a is 1 °, a is 2 ° and a is 3 °, and there are also four different included angles of the cutting string 20, for example, there are cases where a is 1 °, a is 2 °, a is 3 °, and a is 4 °. Of course, there may be five or more different included angle cutting bars 20. Thus, the spray disk 100 can effectively cut and atomize liquid to be atomized at different rotating speeds, and can achieve good atomization effect at different rotating speeds, so that the application of the product is wider.

In this embodiment, the included angle corresponding to the cutting strip 20 with the quantity accounting for X in the plurality of cutting strips 20 satisfies: a is more than 2.5 degrees and less than or equal to 5 degrees. The included angle that the quantity accounts for the cutting strip 20 that is Y among a plurality of cutting strips 20 and corresponds satisfies: a is more than 1.5 degrees and less than or equal to 2.5 degrees. The included angle that the quantity accounts for the cutting strip 20 that is Z among a plurality of cutting strips 20 to correspond satisfies: a is more than or equal to 0 degree and less than or equal to 1.5 degrees. Wherein, X is more than 100 percent and Y is more than Z is more than 0, and X + Y + Z is less than or equal to 1.

In other words, when X + Y + Z is 1, all the included angles a in the same tray 10 satisfy: a is more than or equal to 0 degree and less than or equal to 5 degrees, when X + Y + Z is less than 1, the same tray body 10 is shown to satisfy the distribution angle, and partial included angles a: a is more than 5 degrees and less than or equal to 10 degrees.

For ease of understanding, a specific example is illustrated. When one spray disk 100 has 100 cutting strips 20, and 50 cutting strips 20 satisfying 2.5 ° < a ≦ 5 °, 30 cutting strips 20 satisfying 1.5 ° < a ≦ 2.5 °, and 20 cutting strips 20 satisfying 0 ° < a ≦ 1.5 °, respectively, X is 50%, Y is 30%, and Z is 20%.

TABLE 1

In table 1, rpm represents the number of rotations per minute of the spray disk 100.

In table 1, when the rotation speed of the nozzle plate 100 is between 0rpm and 4000rpm, the included angle a satisfies: when a is more than 2.5 degrees and less than or equal to 5 degrees, the better atomization effect can be achieved, and the particle size of the atomized liquid is approximately between 180 and 150 mu m.

When the rotation speed of the spray plate 100 is 4000-: when a is more than 1.5 degrees and less than or equal to 2.5 degrees, the better atomization effect can be achieved, and the particle size of the atomized liquid is approximately between 150 and 100 mu m.

When the rotating speed of the spray plate 100 is more than 8000rpm, and the included angle a satisfies the following conditions: when a is more than or equal to 0 degree and less than or equal to 1.5 degrees, the better atomization effect can be achieved, and the particle size of the atomized liquid is approximately less than 80 mu m.

In order to achieve the desired atomization effect of the spray plate 100 at different rotational speeds (e.g., particle size between 100 μm and 200 μm). Therefore, in this embodiment, all the cutting strips 20 in the same tray 10 are divided into three types, wherein the included angle a of one type of cutting strip 20 satisfies: a is more than 2.5 degrees and less than or equal to 5 degrees, and the included angle a of one type of cutting strip 20 satisfies the following conditions: a is more than 1.5 degrees and less than or equal to 2.5 degrees, and the included angle a of the rest cutting strips 20 meets the following requirements: a is more than or equal to 0 degree and less than or equal to 1.5 degrees. Thus, three cutting strips 20 with different inclination degrees are distributed on the same disc body 10. Thus, when the spray plate 100 is at different rotation speeds, a better atomization effect can be achieved. Further, the proportion of the three types of cutting strips 20 is different, for example, the proportion of the number of the cutting strips 20 with the included angle a of more than 2.5 degrees and less than or equal to 5 degrees is higher, which is beneficial to increasing the grain diameter of atomized liquid drops, and meanwhile, the included angle a of partial cutting strips 20 is satisfied: a is more than 1.5 degrees and less than or equal to 2.5 degrees, and a is more than or equal to 0 degrees and less than or equal to 1.5 degrees, so that the particle size of partial liquid drops can be reduced. Generally, too high a droplet size is not conducive to saving the amount of the drug and the spraying range, and too low a droplet size will prevent the drug from falling onto the designated crops. Therefore, the arrangement can satisfy the better atomization effect in a comprehensive view no matter the spray disk 100 is in a high-speed operation state, a medium-speed operation state or a low-speed operation state.

It should be noted that, when the shape of the cutting bar 20 is a rectangle, the extending direction thereof is the length direction thereof, and when the shape of the cutting bar 20 is an isosceles triangle, the extending direction thereof is the angular bisector direction of the vertex angle thereof, and so on.

In the spray disk 100 in the view of fig. 4 and 5, the cutting strip 20 is rotated counterclockwise or clockwise by a certain angle based on the center of mass of the cutting strip as a center of the disk 10, and finally the cutting strip 20 is inclined with respect to the radial direction of the disk 10. For example, if the clockwise is negative and the counterclockwise is positive, if the cutting strip 20 is rotated clockwise by a certain angle, the included angle a is negative, and if the cutting strip 20 is rotated counterclockwise by a certain angle, the included angle a is positive, where the above-mentioned included angle a refers to an absolute value, in other words, the included angle a can also be understood to satisfy: a is more than or equal to minus 5 degrees and less than or equal to 5 degrees. Thus, when it is determined that the motor 200 drives the spray tray 100 to rotate clockwise or counterclockwise, the corresponding spray tray 100 may be selected. In the present embodiment, referring to fig. 4, the relative position shown in fig. 4 illustrates that the cutting strip 20 located at the top of the disc body 10 is rotated counterclockwise by an angle a around the center of mass of the cutting strip on the basis of the radial extension of the disc body 10, so that the cutting strip 20 is finally inclined with respect to the radial direction of the disc body 10. Specifically, in conjunction with fig. 5, fig. 5 shows three cutting strips 20, and the included angles a of the three cutting strips 20 rotated counterclockwise are included angle a1, included angle a2 and included angle a3, respectively. Included angle a1, included angle a2, and included angle a3 may or may not be equal.

The central portion 11 of the tray body 10 is connected with the output shaft of the motor 200, under the driving of the motor 200, the tray body 10 rotates, after the liquid to be atomized, which is positioned above the tray body 10, is input onto the tray body 10, the liquid firstly enters the blank area 13 on the tray body 10, under the centrifugal action, the liquid directly flows into the cutting area 14, and the plurality of cutting strips 20 in the cutting area 14 simultaneously cut the liquid flowing into the cutting area 14, so that the liquid is atomized. For example, the cutting strip 20 extends at an angle a with respect to the radial direction of the disc body 10 due to the reasonable design of the parameters of the cutting strip 20. In the same tray 10, all the cutting strips 20 have the following included angles: a is more than or equal to 0 degree and less than or equal to 5 degrees. Moreover, the included angle corresponding to the cutting strip 20 with the quantity accounting for X in the plurality of cutting strips 20 satisfies: a is more than 2.5 degrees and less than or equal to 5 degrees. The included angle that the quantity accounts for the cutting strip 20 that is Y among a plurality of cutting strips 20 and corresponds satisfies: a is more than 1.5 degrees and less than or equal to 2.5 degrees. The included angle that the quantity accounts for the cutting strip 20 that is Z among a plurality of cutting strips 20 to correspond satisfies: a is more than or equal to 0 degree and less than or equal to 1.5 degrees. Wherein, X is more than 100 percent and Y is more than Z is more than 0. Thus, the spray disk 100 can effectively cut and atomize liquid to be atomized at different rotating speeds, and can achieve good atomization effect at different rotating speeds, so that the application of the product is wider.

Optionally, X is greater than or equal to 50% and less than 100%, and the included angle corresponding to the cutting strip 20 with the number of the plurality of cutting strips 20 in proportion to X satisfies: a is 3.3 ° or a is 3.5 °. For example, X may be selected from 50%, 60%, 70%, 80%, 90%, 98%, etc.

Optionally, Y is greater than or equal to 10% and less than or equal to 50%, and the included angle corresponding to the cutting strip 20 with the number of the plurality of cutting strips 20 accounting for Y satisfies: a is 2 °, or a is 2.5 °. For example, Y may be selected from 10%, 20%, 30%, 40%, 50%, etc.

Optionally, Z is greater than 0 and less than or equal to 10%, and the included angle corresponding to the cutting strip 20 with the quantity of Z in the plurality of cutting strips 20 satisfies: a is 0 ° or a is 1.5 °. For example, Z may be selected from 1%, 5%, 10%, etc.

Under one embodiment, X is more than or equal to 50% and less than 100%, and the included angle corresponding to the cutting strip 20 with the quantity accounting for X in the plurality of cutting strips 20 satisfies: a is 3.3 ° or a is 3.5 °. Y is more than or equal to 10% and less than or equal to 50%, and the included angle corresponding to the cutting strip 20 with the quantity accounting for Y in the plurality of cutting strips 20 satisfies: a is 2 °, or a is 2.5 °. Z is more than 0 and less than or equal to 10 percent, and the included angle corresponding to the cutting strip 20 with Z in the number ratio of the plurality of cutting strips 20 meets the following requirements: a is 0 ° or a is 1.5 °.

It should be noted that X may be selected from 50%, 60%, 70%, 80%, 90%, 98%, etc., and the included angle of the corresponding cutting strip 20 may satisfy: a is 3.3 ° or a is 3.5 °. Y may be selected from 10%, 20%, 30%, 40%, 50%, etc., and the included angle of the corresponding cutting strip 20 may satisfy: a is 2 °, or a is 2.5 °. Z can be selected from 1%, 5%, 10% and the like, and the included angle of the corresponding cutting strip 20 can satisfy the following conditions: a is 0 ° or a is 1.5 °. The various data may be selected to form a particular spray disk 100.

For example, in a specific example, X is selected to be 60%, and the included angle corresponding to 60% of the cutting strips 20 satisfies: a is 3.3 °. Y is 30 percent, and the included angle corresponding to the 30 percent cutting strip 20 meets the following requirements: a is 2. Z is 10 percent, and the included angle corresponding to the cutting strip 20 accounting for 10 percent meets the following requirements: a is 1.5 °.

In this specific example, it should be noted that the arrangement of the cutting strips 20 may be regular, and assuming that there are 100 cutting strips 20 on the spray tray 100, optionally, in the circumferential direction of the tray body 10, the included angle corresponding to 60 consecutive cutting strips 20 is 3.3 °, the included angle corresponding to 30 consecutive cutting strips 20 is 2 °, and the included angle corresponding to 10 consecutive cutting strips 20 is 1.5 °. Of course, the cutting strips 20 may be randomly distributed, that is, the distribution of the cutting strips is random and irregular. The examples are merely examples, and in practical implementation, the distribution of the cutting strips 20 is performed according to actual requirements.

Optionally, in the cutting strips 20 with the number ratio X, all the cutting strips 20 have the same included angle. And/or the included angles corresponding to all the cutting strips 20 in the cutting strips 20 with the number ratio of Y in the plurality of cutting strips 20 are equal. And/or the included angles corresponding to all the cutting strips 20 in the cutting strips 20 with the number ratio Z in the plurality of cutting strips 20 are equal.

In a specific example, in the cutting strips 20 with the ratio of X, all the cutting strips 20 have an included angle of 4 °. In the Y ratio of the cutting strips 20, all the cutting strips 20 have an included angle of 2.2 °. In the cutting strips 20 with the ratio of Z, all the cutting strips 20 have an included angle of 1.3 °.

Of course, in a specific example, in the cutting strips 20 with the ratio of X, the included angle corresponding to a part of the cutting strips 20 is 4 °, and the included angle corresponding to the remaining part of the cutting strips 20 is 4.5 °. In the Y ratio of the cutting strips 20, all the cutting strips 20 have an included angle of 2.2 °.

Of course, it is also possible that all the cutting strips 20 have different included angles on the same tray 10.

Alternatively, in the same tray 10, all the cutting strips 20 have the corresponding included angles: a is greater than 0 DEG, and the extending directions of all the cutting strips 20 are the same in the inclined direction with respect to the radial direction of the disc body 10.

In other words, in the same disc 10, all the cutting strips 20 are rotated counterclockwise by the angle a from the center of mass on the basis of the radial extension of the disc 10. Alternatively, all the cutting strips 20 are rotated clockwise by an angle a based on the center of mass of the cutting strips on the basis of the radial extension of the disc body 10. When the inclined directions of all the cutting strips 20 in the same tray 10 are the same, the distribution of all the cutting strips 20 on the tray 10 is more regular.

Of course, it is also possible that most of the cutting strips 20 are rotated clockwise by the angle a, and the rest of the cutting strips 20 are rotated counterclockwise by the angle a. Alternatively, most of the cutting bars 20 are rotated counterclockwise by the angle a, and the remaining cutting bars 20 are rotated clockwise by the angle a.

The direction indicated by the arrow in fig. 5 is the direction of flow of the liquid.

In this embodiment, referring to fig. 5, the cutting strip 20 includes a cutting strip body 21 and a cutting strip tip 22 sequentially connected along the extending direction, and the cutting strip tip 22 is close to the central portion 11 relative to the cutting strip body 21. The bearing surface 12 is a plane, the projection of the center of mass of the cutting strip 20 on the bearing surface 12 is a first point, the projection of one end, far away from the cutting strip body 21, of the cutting strip tip 22 on the bearing surface 12 is a second point, and the extending direction of the cutting strip 20 is defined by the connecting line direction of the first point and the second point. The center of the disk 10 is located at the center 11, and the connecting line between the center of mass of the cutting strip 20 and the center of the disk 10 is in the radial direction of the disk 10.

The strip body 21 of the strip 20 is positioned adjacent the peripheral edge 15 of the disc 10 such that the outlet 32 of the flow path 30 is defined by the strip body 21 of two adjacent strips 20 and the peripheral edge 15 of the disc 10.

As can be understood from fig. 5, in two adjacent cutting strips 20, the inlet 31 of the flow channel 30 is defined between the cutting strip tips 22 of the two cutting strips 20, and the outlet 32 of the flow channel 30 is defined between the ends of the cutting strip bodies 21 of the two cutting strips 20 far away from the cutting strip tips 22. The cutting tip 22 of the cutting strip 20 cuts the liquid, and the cut liquid drops enter the flow channel 30 and are discharged through the outlet 32 thereof.

Referring to fig. 6 to 7, fig. 6 to 7 show a second spray disk 100 provided in the present embodiment, which is basically the same as the first spray disk 100 mentioned above, except that:

all the cutting strands 20 of the first spray disk 100 shown in fig. 4 are distributed in a single cutting strand circle, i.e. only one cutting strand circle is contained. All the cutting strips 20 of the second spray disk 100 shown in fig. 6 are distributed in a plurality of cutting strip turns, and in particular, it comprises two cutting strip turns. It should be noted that each cutting strip loop comprises a plurality of cutting strips 20. In addition, in other embodiments, the number of the cutting strips is not limited, and all the cutting strips 20 may be distributed in at least two cutting strips, for example, three cutting strips, four cutting strips, and the like.

Referring to fig. 6, the two cutting coils are an inner cutting coil and an outer cutting coil, respectively, and ends of the cutting tip portions 22 of the plurality of cutting strips 20 included in the inner cutting coil, which are far away from the cutting strip body 21, are distributed along a third preset circle 103 (shown by a dotted line). The ends of the cutting strand bodies 21 of the plurality of cutting strands 20 contained in the outer cutting strand loops remote from the cutting strand tip 22 are distributed along a fourth predetermined circle 104 (shown by dashed lines). 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 spray disk 100 from the liquid inlet pipe 300, the liquid firstly enters the blank area 13, then flows to the cutting area 14 under the centrifugal action, is firstly cut into relatively atomized liquid drops by the plurality of cutting strips 20 in the inner cutting strip circle, then flows to the outer cutting strip circle under the centrifugal action, is cut by the plurality of cutting strips 20 in the outer cutting strip circle, and finally is sprayed out from the peripheral edge 15 of the disk body 10, and the overall atomization effect is good.

According to the spraying assembly 1000 provided by the embodiment, the working principle of the spraying assembly 1000 is as follows:

referring to fig. 1, when the motor 200 is started, the spray tray 100 is driven to rotate, and after the liquid inlet pipe 300 enters the liquid, the liquid is input above the spray tray 100, so that the liquid falls into the blank area 13 of the tray body 10.

Taking the spray disk 100 in fig. 4 as an example, during the rotation of the disk body 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 cutting strips 20 in the cutting area 14, the liquid flows out from the flow channel 30 between two adjacent cutting strips 20, and finally is sprayed out from the peripheral edge 15 of the disk body 10 under the action of the centrifugal force and the gravity.

Taking the spray disk 100 in fig. 6 as an example, during the rotation of the disk body 10, the liquid falling into the blank area 13 directly flows to the cutting area 14 in a freely divergent manner under the action of the centrifugal force, and after being cut by the cutting strips 20 in the inner cutting strip circle in the cutting area 14, the liquid flows out from the flow channel 30 between two adjacent cutting strips 20 in the inner cutting strip circle, then enters the outer cutting strip circle, is cut by the cutting strips 20 in the outer cutting strip circle, flows out from the flow channel 30 between two adjacent cutting strips 20 in the outer cutting strip circle, and finally is sprayed out from the peripheral edge 15 of the disk body 10 under the action of the centrifugal force and the gravity force.

Referring to the relative position in fig. 1, when liquid flows from the liquid inlet pipe 300 to the spray tray 100, the flow direction is vertical, the rotation axis of the tray body 10 is vertical, and after the liquid flows into the tray body 10, in the process of the rotation of the tray body 10, due to the centrifugal effect, the speed direction of the liquid has a certain deviation angle with the radial direction of the tray body 10 in the process of the liquid flowing from the central portion 11 to the peripheral edge 15 of the tray body 10, so that the cutting strip 20 is obliquely arranged, the extending direction of the cutting strip 20 forms an included angle a with the radial direction of the tray body 10, and the cutting and atomization can be better performed along the flow direction of the liquid. Through reasonable setting of the included angle a and the different proportion of the included angle a, the liquid can be fully atomized under different rotating speeds of the spray plate 100. Of course, when the flow rate, the type, and the like of the liquid are different and the rotation speed of the spray tray 100 is different, the specific implementation is performed, the included angle a and the different proportion of the included angle a are correspondingly selected.

For the technical scheme provided by the embodiment, due to the adoption of the parameter design, the spray disk 100 can still realize effective cutting and atomization of the liquid to be atomized at different rotating speeds, and therefore, the product can be more widely applied by the structure.

In summary, the embodiment of the present invention provides a spraying tray 100, a spraying assembly 1000 and an unmanned device, wherein a central portion 11 of a tray body 10 is connected to an output shaft of a motor 200, the tray body 10 rotates under the driving of the motor 200, after a liquid to be atomized above the tray body 10 is inputted onto the tray body 10, the liquid first enters a blank space 13 on the tray body 10, the liquid directly flows into a cutting area 14 under the centrifugal action, and a plurality of cutting strips 20 in the cutting area 14 simultaneously cut the liquid flowing into the cutting area 14 to atomize the liquid. The cutting strip 20 extends at an angle a with respect to the radial direction of the disc body 10. The included angle a of the same spray plate 100 can be only one for a specific use environment, and different environments can be adapted by providing a plurality of spray plates 100 of different types. Or, the same spray disk 100 has a plurality of included angles a to adapt to the environment with variable rotating speed. Thus, the spray disk 100 can effectively cut and atomize liquid to be atomized at different rotating speeds, and can achieve good atomization effect at different rotating speeds, so that the application of the product is wider.
