Description

Atomizing disc, atomizing device and operating equipment

[0001] This application claims priority to the patent application filed on August 27, 2024, with China National Intellectual Property Administration, application number 202411181859.7, entitled "An atomizing disc, atomizing device and operating equipment". Technical Field

[0002] This invention relates to the field of atomizing device technology, and more particularly to an atomizing disc, atomizing device, and operating equipment. Background Technology

[0003] Atomizing devices are designed to atomize liquids (e.g., pesticides or water) into tiny droplets using nozzles or high-speed airflow for spraying crops. During atomization, the liquid is typically dispersed by ribs on the surface of the atomizing disc, and then detaches from the disc's edge, falling onto the crops under gravity. Existing atomizing discs suffer from low atomization efficiency due to design limitations, resulting in a trade-off between high mist output and effective atomization. Specifically, increasing the mist output involves supplying a large amount of liquid to the disc surface. However, as the liquid falls onto the disc, the high flow rate and low atomization efficiency can cause blockages, hindering the ribs' ability to disperse the liquid and thus affecting the final atomization effect. Conversely, maintaining a good atomization effect involves reducing the liquid flow to the disc surface. While this ensures proper rib dispersion, the mist output is lower.

[0004] In view of this, it is necessary to improve the atomizing disc in the existing technology to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that existing atomizing discs have low atomization efficiency due to their design limitations, and thus the problem that the amount of mist output and the atomization effect cannot be balanced.

[0006] To achieve the above objectives, in a first aspect, the present invention provides an atomizing disc, comprising:

[0007] The disc body has upper and lower guide ribs constructed on its longitudinal sides. At least one opening is formed in the enclosed area formed by the upper guide ribs, penetrating the disc body downwards. A distribution cylinder is formed at the bottom of the disc body, communicating with the opening. At least one liquid outlet is formed laterally in the distribution cylinder, communicating with the opening and conveying liquid to the lower guide ribs. The liquid outlet is formed on the radial inner side of the lower guide ribs.

[0008] As a further improvement of the present invention, a pivot portion with a through hole is formed on the radial inner side of the disc body, a distribution cylinder is formed on the periphery of the pivot portion, and an annular base plate covering the lower guide rib is sleeved on the outer side of the distribution cylinder, and the annular base plate extends radially inward to form a retaining ring that at least partially surrounds the bottom of the distribution cylinder.

[0009] As a further improvement of the present invention, the atomizing disk further includes: an annular top disk coaxially disposed above the disk body and having an opening, the annular top disk covering the upper guide ribs, and the pivot portion extending longitudinally into the opening to define an annular liquid inlet for liquid to flow into the disk body.

[0010] As a further improvement of the present invention, the disc body is driven by the pivot to rotate to form a central rotation axis. The upper and lower guide ribs are both straight, and the planes where the upper and lower guide ribs are located intersect the central rotation axis.

[0011] As a further improvement of the present invention, the upper guide rib is longitudinally protruding on the surface of the disk and is inclined relative to the disk. The angle formed between the plane of the upper guide rib along its protruding direction and the plane of the disk is greater than or equal to 45 degrees and less than or equal to 135 degrees. The lower guide rib is longitudinally protruding on the surface of the disk and is inclined relative to the disk. The angle formed between the plane of the lower guide rib along its protruding direction and the plane of the disk is greater than or equal to 45 degrees and less than or equal to 135 degrees.

[0012] As a further improvement of the present invention, two adjacent upper guide ribs form an upper guide groove, and two adjacent lower guide ribs form a lower guide groove. The upper guide ribs are laterally provided with a plurality of first protrusions extending into the upper guide groove, and the lower guide ribs are laterally provided with a plurality of second protrusions extending into the lower guide groove.

[0013] As a further improvement of the present invention, the upper guide ribs are evenly spaced and configured in at least two rings from the inside to the outside. A first spreading annular surface is formed between the upper guide ribs in the inner ring and the upper guide ribs in the outer ring. The enclosed area is the inner circumferential area of ​​the innermost upper guide rib, the first spreading annular surface, or the outer circumferential area of ​​the outermost upper guide rib.

[0014] The lower guide ribs are evenly spaced and arranged in two rings from the inside to the outside. The lower guide ribs in the inner ring and the lower guide ribs in the outer ring form a second spreading annular surface. The liquid outlet is formed on the radial inner side of the innermost lower guide rib.

[0015] Both the first and second spreading annular surfaces are flat surfaces.

[0016] As a further improvement of the present invention, the arrangement density of the upper guide ribs located in the inner ring is less than that of the upper guide ribs located in the outer ring, and the annular top plate at least covers the upper guide ribs located in the innermost ring, and the upper guide ribs are in contact with the annular top plate or form a first gap.

[0017] The arrangement density of the lower guide ribs located in the inner ring is less than that of the lower guide ribs located in the outer ring, and the lower guide ribs are in contact with the annular chassis or form a second gap.

[0018] As a further improvement of the present invention, the openings are configured as a plurality and are evenly spaced around the pivot, a spoke is formed between two adjacent openings, the surface profile of the opening gradually expands from the inside to the outside, the side profile of the opening gradually expands from top to bottom along the longitudinal direction, and a blocking portion is formed on the surface of the spokes that extends laterally to the top of the opening.

[0019] As a further improvement of the present invention, the diameter of the spoke near the pivot is greater than or equal to a first preset value; the difference between the diameter of the opening at the same radial distance from the central rotation axis and the spoke width is less than or equal to a second preset value; the longitudinal thickness of the opening is greater than or equal to a third preset value; the outlet spacing at the edges of two adjacent upper guide ribs on the outermost ring and the outlet spacing at the edges of two adjacent lower guide ribs on the outermost ring are both greater than or equal to a fourth preset value; the ratio formed by the spacing between two adjacent upper guide ribs on the inner ring and the spacing between two adjacent upper guide ribs on the outer ring is greater than or equal to a fifth preset value; the ratio formed by the spacing between two adjacent lower guide ribs on the inner ring and the spacing between two adjacent lower guide ribs on the outer ring is greater than or equal to a sixth preset value; and the spacing between the upper guide ribs and the lower guide ribs is greater than or equal to a seventh preset value.

[0020] Secondly, based on the same inventive concept, this invention also discloses an atomizing device, comprising:

[0021] The atomizing disc of any of the first aspects includes a liquid inlet disc disposed on top of the atomizing disc to supply liquid to the atomizing disc, and a drive assembly for driving the atomizing disc to rotate about the axis of the atomizing disc.

[0022] As a further improvement of the present invention, the atomizing device also includes:

[0023] An auxiliary disk is coaxially positioned at the bottom of the atomizing disk. Multiple columns are evenly spaced around the circumference of the auxiliary disk. The columns extend longitudinally to the outer edge of the atomizing disk, and the direction of extension of the columns is parallel to the axis of the atomizing disk.

[0024] Thirdly, based on the same inventive concept, this invention discloses a working device, comprising:

[0025] The operation body, and at least one atomizing device as described in any of the second aspects connected to the operation body; wherein the operation body includes aerial operation equipment, ground operation equipment or water surface operation equipment.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] An upper guide rib and a lower guide rib are constructed on both sides of the longitudinal direction of the disc body. At least one opening is formed in the enclosed area formed by the lower guide rib, which penetrates the disc body downward. A distribution cylinder is protruding from the bottom of the disc body to form a connecting opening. At least one liquid outlet is formed on the side of the distribution cylinder to communicate with the opening and to deliver liquid to the lower guide rib. The liquid outlet is formed on the radial inner side of the lower guide rib. When liquid flows into the surface of the atomizing disc, it is divided into two parts. One part of the liquid is torn into tiny droplets by the upper guide ribs, while the other part flows into the distribution cylinder from the opening and then into the lower guide ribs through the outlet on the side of the distribution cylinder. The lower guide ribs then tear the other part of the liquid into tiny droplets. The liquid is atomized by both the upper and lower guide ribs simultaneously, which improves the atomization effect of the atomizing disc. Based on this, the liquid flow rate can be increased, thereby increasing the mist output of the atomizing disc. At the same time, the improved atomization efficiency can effectively prevent liquid blockage when the flow rate is large, thus ensuring the atomization effect of the atomizing disc. Ultimately, this solves the problem of low atomization efficiency in existing atomizing discs due to their design limitations, which leads to a trade-off between mist output and atomization effect.

Detailed Implementation

[0040] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0041] It should be noted that in this invention, "longitudinal" refers to the direction of the Y-axis shown in Figure 1, and "lateral" refers to the direction of the X-axis shown in Figure 1.

[0042] Referring to Figures 1 to 11, the present invention illustrates a specific embodiment of an atomizing disc 10 and an atomizing device 100. The atomizing disc 10 is specifically assembled in the atomizing device 100, and the atomizing disc 10 can be regarded as a component constituting the atomizing device 100. The atomizing device 100 can atomize the liquid medicine (i.e., a lower concept of liquid) using different atomization methods. For example, the atomizing device 100 can employ centrifugal atomization or pressure atomization. In the following description, the atomizing device 100 is used to atomize liquid by centrifugal atomization as an example. Specifically, the atomizing disk 10 is driven to rotate around the axis of the atomizing disk 10 by the drive component 60 included in the atomizing device 100 (i.e., the atomizing disk 10 rotates around the central rotation axis A). The liquid flows towards the edge of the atomizing disk 10 under the action of centrifugal force, and the liquid is torn into tiny droplets by the guide ribs (i.e., the upper guide rib 11 and / or the lower guide rib 12 described below), based on which the spraying operation is carried out on crops.

[0043] Referring to Figure 2, the atomizing device 100 includes: an atomizing disk 10, a liquid inlet disk 50 disposed on the top of the atomizing disk 10 to supply liquid to the atomizing disk 10, and a drive assembly 60 for driving the atomizing disk 10 to rotate around its axis. Liquid is supplied to the atomizing disk 10 through the liquid inlet disk 50, and the atomizing disk 10 is driven to rotate around its axis (i.e., the atomizing disk 10 rotates around its central rotation axis A) by the drive assembly 60. The liquid in the atomizing disk 10 flows towards the edge of the atomizing disk 10 under centrifugal force, and during the flow, it is torn into tiny droplets by the guide ribs (i.e., upper guide ribs 11 and / or lower guide ribs 12) constructed inside the atomizing disk 10, and then flies away from the atomizing disk 10.

[0044] To further ensure the atomization effect of the atomizing device 100, as shown in Figure 1, the atomizing device 100 also includes an auxiliary disk 20 coaxially disposed at the bottom of the atomizing disk 10. The auxiliary disk 20 is provided with a plurality of columns 21 evenly spaced around its circumference. The columns 21 extend longitudinally to the outer peripheral edge of the atomizing disk 10, and the extending direction of the columns 21 is parallel to the axis of the atomizing disk 10 (i.e., the central rotation axis A). The liquid is torn into tiny droplets by the guide ribs (i.e., upper guide ribs 11 and / or lower guide ribs 12) constructed inside the atomizing disk 10 to achieve the first atomization of the liquid. When the droplets flow out from the edge of the atomizing disk 10, the droplets are torn into even smaller droplets again by the columns 21 arranged circumferentially on the auxiliary disk 20 to achieve the second atomization of the liquid. The columns 21 can also tear the liquid that has not been torn by the atomizing disk 10 into tiny droplets to reduce the size of the liquid particles, thereby further ensuring the atomization effect of the atomizing device 100. In this invention, the atomizing device 100 may include only the atomizing disk 10, the liquid inlet disk 50 and the driving component 60 (i.e., a partial perspective view of the atomizing device 100 shown in FIG. 2), or it may include the atomizing disk 10, the liquid inlet disk 50, the driving component 60 and the auxiliary disk 20 simultaneously (i.e., a perspective view of the atomizing device 100 shown in FIG. 1). This embodiment does not specifically limit this.

[0045] Referring to Figures 3 to 6, the atomizing disk 10 includes: a disk body 30, with upper guide ribs 11 and lower guide ribs 12 respectively constructed on the longitudinal sides of the disk body 30. At least one opening 13 is formed in the enclosed area formed by the upper guide ribs 11, penetrating the disk body 30 downward. A distribution cylinder 14 is formed at the bottom of the disk body 30, communicating with the opening 13. At least one liquid outlet 141 is formed laterally in the distribution cylinder 14, communicating with the opening 13 and conveying liquid to the lower guide ribs 12. The liquid outlet 141 is formed on the radial inner side of the lower guide ribs 12. Since the upper guide rib 11 and the lower guide rib 12 are respectively constructed on the longitudinal sides of the disc 30, the liquid can be torn into tiny droplets by the upper guide rib 11 alone; or the liquid can be torn into tiny droplets by the lower guide rib 12 alone; or the liquid can be divided into two parts, one part of the liquid is torn into tiny droplets by the upper guide rib 11, and the other part of the liquid flows into the distribution cylinder 14 from the opening 13, and flows into the lower guide rib 12 through the liquid outlet 141 opened on the side of the distribution cylinder 14, so that the other part of the liquid is torn into tiny droplets by the lower guide rib 12. This achieves rapid atomization of large flow of liquid. This embodiment does not make specific limitations on this. Preferably, the liquid is divided into two parts, and the liquid is torn into tiny droplets by the upper guide rib 11 and the lower guide rib 12 respectively. This allows the liquid to be atomized simultaneously by the upper guide rib 11 and the lower guide rib 12, thereby improving the atomization efficiency of the atomizing disk 10. Based on this, the liquid flow rate can be increased, thereby increasing the mist output of the atomizing disk 10. At the same time, the improved atomization efficiency can also effectively prevent the liquid from clogging when the flow rate is large, thus ensuring the atomization effect of the atomizing disk 10. Ultimately, this solves the problem of low atomization efficiency in existing atomizing disks due to their design limitations, and the resulting inability to balance mist output and atomization effect.

[0046] Specifically, as shown in Figure 3, a drive shaft (not shown) extends from the bottom of the drive assembly 60. A pivot portion 16 with a through hole 161 is formed on the radially inner side of the disc 30. The disc 30 is fitted onto the outside of the drive shaft through the through hole 161 formed by the pivot portion 16. The disc 30 is driven by the pivot portion 16 to rotate and form a central rotation axis A. The drive shaft is driven by the drive assembly 60 to rotate around its own axis (i.e., the drive shaft rotates around the central rotation axis A), so that the pivot portion 16 fitted onto its outside rotates around the central rotation axis A, and then the pivot portion 16 drives the disc 30 to rotate around the central rotation axis A. Regarding the specific assembly method of the disc 30 and the drive shaft, the disc 30 can be fixedly sleeved on the outside of the drive shaft, in which case the shape of the through hole 161 is not specifically limited; or the disc 30 can be movably sleeved on the outside of the drive shaft, in which case the outline of the through hole 161 is limited to a non-standard circle, the inner sidewall of the through hole 161 fits against the outer side of the drive shaft, and the disc 30 does not rotate relative to the drive shaft. As long as the disc 30 can be driven to rotate around the central rotation axis A by the drive assembly 60, this embodiment does not make specific limitations on this.

[0047] Similarly, as shown in Figure 7, a fixing part 22 with a through hole 221 is formed on the radially inner side of the auxiliary disk 20, and a drive core (not shown) extends outward from the inside of the drive shaft (not shown). The auxiliary disk 20 is sleeved on the outside of the drive core through the through hole 221 formed by the fixing part 22. In this invention, the auxiliary disk 20 can rotate about the axis of the auxiliary disk 20 relative to the drive assembly 60 (i.e., the auxiliary disk 20 rotates about the central rotation axis A), or it can remain stationary relative to the drive assembly 60. Specifically, the drive assembly 60 can drive the drive shaft and drive core to rotate around the central rotation axis A, so that the drive shaft drives the disk body 30 to rotate around the central rotation axis A, and the drive core drives the auxiliary disk 20 to rotate around the central rotation axis A. The rotation direction and speed of the two can be the same or opposite, the same or different; this embodiment does not specifically limit this. Alternatively, the drive assembly 60 can only drive the drive shaft to rotate around the central rotation axis A, so that the drive shaft drives the disk body 30 to rotate around the central rotation axis A, while the drive core and auxiliary disk 20 remain stationary. The specific assembly method of the auxiliary disk 20 and drive core is similar to the aforementioned assembly method of the disk body 30 and drive shaft, and will not be repeated here.

[0048] Referring to Figures 1 and 3, the atomizing disk 10 further includes an annular top disk 40 coaxially disposed above the disk body 30 and having an opening (not labeled). The annular top disk 40 covers the upper guide rib 11, and the pivot portion 16 extends longitudinally into the opening to define an annular liquid inlet 51 for liquid to flow into the disk body 30. The liquid inlet disk 50 disposed at the top of the atomizing disk 10 is used to hold liquid. An annular liquid outlet 52 extending into the annular liquid inlet 51 is formed at the bottom of the liquid inlet disk 50, and a liquid inlet 53 for liquid to be transported to the liquid inlet disk 50 is formed on the side of the liquid inlet disk 50. The liquid enters the inlet plate 50 through the inlet 53 and flows out through the annular outlet 52. Then it flows into the atomizing plate 10 through the annular inlet 51. After the liquid flows into the atomizing plate 10, the liquid is stably contained inside the atomizing plate 10 due to the restriction effect of the annular top plate 40 covering the upper guide ribs 11, so as to prevent the liquid from splashing after flowing into the atomizing plate 10.

[0049] Referring to Figures 6 and 8, the distribution cylinder 14 is formed around the pivot portion 16. An annular base 15 covering the lower guide rib 12 is fitted on the outside of the distribution cylinder 14 to guide the liquid flowing out of the outlet 141 to the lower guide rib 12. The annular base 15 extends radially inward to form a retaining ring 151 that at least partially surrounds the bottom of the distribution cylinder 14. Liquid flows into the atomizing disk 10 from the annular inlet 51. A portion of the liquid flows into the distribution cylinder 14 from the opening 13 and then flows to the lower guide rib 12 through the outlet 141 on the side of the distribution cylinder 14. At the same time, the annular base 15 completely guides the liquid flowing out of the outlet 141 to the lower guide rib 12 to prevent the liquid from falling down from the atomizing disk 10 due to gravity when flowing out of the outlet 141. This ensures that all the liquid flowing out of the outlet 141 flows to the lower guide rib 12 and is torn into tiny droplets by the lower guide rib 12, thus ensuring the final atomization effect. Since the annular base 15 is sleeved on the outside of the distribution cylinder 14, in order to prevent liquid from flowing out from the gap formed between the annular base 15 and the distribution cylinder 14, the annular base 15 can be configured to at least partially surround the bottom of the distribution cylinder 14 (that is, the aforementioned annular base 15 extends radially inward to form a retaining ring 151 that at least partially surrounds the bottom of the distribution cylinder 14). The retaining ring 151 at least partially surrounds the bottom of the distribution cylinder 14, thereby ensuring that the liquid flowing out from the liquid outlet 141 flows to the lower guide rib 12 under the guidance of the annular base 15, thereby preventing liquid waste and increasing the mist output of the atomizing disc 10, thus ensuring the final atomization effect.

[0050] As shown in Figures 5 and 6, both the upper guide rib 11 and the lower guide rib 12 are straight lines. The planes where the upper guide rib 11 and the lower guide rib 12 are located intersect the central rotation axis A. The centers of the upper guide rib 11 and the lower guide rib 12 are both located on the central rotation axis A. In other words, the upper guide rib 11 and the lower guide rib 12 are both set on the radius line of the disk body 30. Thus, the upper guide rib 11 and the lower guide rib 12 are arranged in a gradually expanding manner from the center of the disk body 30 to ensure the uniformity of the dispersion of the liquid flowing at different positions on the plane of the disk body 30 by the upper guide rib 11 and the lower guide rib 12 at different positions, thereby ensuring the final atomization effect.

[0051] Meanwhile, the upper guide rib 11 protrudes longitudinally from the surface of the disk body 30 and is inclined relative to the disk body 30. The plane in which the upper guide rib 11 protrudes (i.e., the plane in which the upper guide rib 11 protrudes) and the plane in which the disk body 30 is located form an angle greater than or equal to 45 degrees and less than or equal to 135 degrees. The lower guide rib 12 protrudes longitudinally from the surface of the disk body 30 and is inclined relative to the disk body 30. The plane in which the lower guide rib 12 protrudes (i.e., the plane in which the lower guide rib 12 protrudes) and the plane in which the disk body 30 is located form an angle greater than or equal to 45 degrees and less than or equal to 135 degrees. Referring to Figure 9, the upper guide rib 11 is used as an example for illustrative explanation. The plane where the disk 30 is located is denoted as m1, and the plane where the upper guide rib 11 is located is denoted as m2. n1 is a plane set at a 45-degree angle relative to m1, and n2 is a plane set at a 135-degree angle relative to m1. m2 can be set within the range formed by n1 and n2. Preferably, the angle formed between the plane where the upper guide rib 11 is located and the plane where the disk 30 is located is 90 degrees. During the flow of liquid on the surface of the disk 30, a liquid film will be generated. The liquid film will accumulate upward along the upper guide rib 11 under the push and acceleration of the upper guide rib 11. Therefore, by setting the upper guide rib 11 at an angle relative to the disk 30, it can be ensured that the liquid film will not accumulate entirely on the bottom side or the top side of the upper guide rib 11, thereby achieving uniform liquid distribution and increasing the uniformity of liquid film expansion, thus ensuring the final atomization effect. Similarly, the lower guide ribs 12 are inclined relative to the disc body 30, which can also effectively ensure the uniformity of liquid distribution and increase the uniformity of liquid film expansion to ensure the final atomization effect. This embodiment will not be described in detail here.

[0052] Two adjacent upper guide ribs 11 form an upper guide groove 112, and two adjacent lower guide ribs 12 form a lower guide groove 122. In order to further ensure the atomization effect (i.e., dispersion effect) of the liquid by the guide ribs (i.e., the upper guide ribs 11 and / or the lower guide ribs 12), the upper guide ribs 11 are laterally protruding with several first protrusions 113 extending into the upper guide groove 112, and the lower guide ribs 12 are laterally protruding with several second protrusions 123 extending into the lower guide groove 122. Thus, when the liquid flows on the upper guide ribs 11, it can be dispersed again by the first protrusions 113 to reduce the size of the liquid particles in the upper layer of the disk 30. Similarly, when the liquid flows on the lower guide ribs 12, it can be dispersed again by the second protrusions 123 to reduce the size of the liquid particles in the lower layer of the disk 30, thereby ensuring the atomization effect of the atomizing disk 10.

[0053] In this invention, the upper guide ribs 11 can be configured as a single ring with uniform spacing, or they can be configured as at least two rings with uniform spacing from the inside out. When an upper guide rib 11 is configured, the enclosed area is either the inner or outer periphery of the upper guide rib 11. When the enclosed area is the inner periphery of the upper guide rib 11, the liquid is divided into two parts from the opening 13. One part of the liquid flows to the upper guide rib 11, which is arranged in a ring, and the liquid is atomized by the upper guide rib 11. The other part of the liquid flows into the distribution cylinder 14 from the opening 13 and flows to the lower guide rib 12 from the liquid outlet 141 on the side of the distribution cylinder 14, where the liquid is atomized by the lower guide rib 12. When the enclosed area is the outer periphery of the upper guide rib 11, the liquid is first atomized by the upper guide rib 11 and then divided into two parts at the opening 13. One part of the liquid flies off the atomizing disk 10 from the upper surface of the disk 30, and the other part of the liquid flows to the lower guide rib 12 from the opening 13, where the liquid is atomized a second time.

[0054] Referring to Figure 10, when at least two rings of upper guide ribs 11 are configured, a first spreading annular surface 111 is formed between the upper guide rib 11 located in the inner ring and the upper guide rib 11 located in the outer ring. The enclosed area is the inner circumferential region of the innermost upper guide rib 11, or the first spreading annular surface 111, or the outer circumferential region of the outermost upper guide rib 11. Figure 10 illustrates this by showing two rings of upper guide ribs 11 arranged from the inside out on the upper surface of the disk 30. The first spreading annular surface 111 is formed between the upper guide rib 11 located in the inner ring (i.e., upper guide rib 11a) and the upper guide rib 11 located in the outer ring (i.e., upper guide rib 11b). The enclosed area is the inner circumferential region of the upper guide rib 11a, or the first spreading annular surface 111, or the outer circumferential region of the upper guide rib 11b. When the enclosed area is the inner circumference of the upper guide rib 11a, the liquid is divided into two parts at the opening 13. One part of the liquid flows to the upper guide rib 11a for the first atomization, and then flows to the upper guide rib 11b for the second atomization via the first spreading annular surface 111. The other part of the liquid flows from the opening to the lower guide rib 12, where it is atomized. When the enclosed area is the first spreading annular surface 111, the liquid first undergoes the first atomization via the upper guide rib 11a, and then is divided into two parts at the opening 13. One part of the liquid flows to the upper guide rib 11b for the second atomization, and the other part of the liquid flows from the opening to the lower guide rib 12, where it is atomized a second time. When the enclosed area is the outer periphery of the upper guide rib 11b, the liquid first undergoes atomization through the upper guide rib 11a, and then flows through the first spreading annular surface 111 to the upper guide rib 11b for a second atomization. At the opening 13, it is divided into two parts. One part of the liquid flies off the atomizing disk 10 from the upper surface of the disk body 30, and the other part of the liquid flows from the opening 13 to the lower guide rib 12, where the liquid undergoes a third atomization.

[0055] Similarly, as shown in Figure 11, the lower guide ribs 12 can be configured as a single ring with uniform spacing, or as at least two rings with uniform spacing from the inside out. When a single ring of lower guide ribs 12 is configured, the liquid outlet 141 is formed on the radially inner side of the lower guide ribs 12, thereby allowing liquid to flow from the opening 13 into the distribution cylinder 14 and through the liquid outlet 141 on the side of the distribution cylinder 14 to the single ring of lower guide ribs 12, where the liquid is atomized. When at least two rings of lower guide ribs 12 are configured, a second spreading annular surface 121 is formed between the lower guide ribs 12 in the inner ring and the lower guide ribs 12 in the outer ring, and the liquid outlet 141 is formed on the radially inner side of the innermost lower guide rib 12. Figure 11 shows an example of two rings of lower guide ribs 12 arranged from the inside out on the lower surface of the disc 30 for illustrative purposes. A second spreading annular surface 121 is formed between the lower guide rib 12 located in the inner ring (i.e., lower guide rib 12a) and the lower guide rib 12 located in the outer ring (i.e., lower guide rib 12b). The liquid flows into the distribution cylinder 14 from the opening 13 and flows to the lower guide rib 12a through the liquid outlet 141 on the side of the distribution cylinder 14 for the first atomization, and then flows to the lower guide rib 12b through the second spreading annular surface 121 for the second atomization.

[0056] It should be noted that both the first spreading annular surface 111 and the second spreading annular surface 121 are flat surfaces. Preferably, the upper flow guide rib 11 is arranged in two rings from the inside out (i.e., the aforementioned upper flow guide rib 11a and upper flow guide rib 11b), and the enclosed area is the inner circumferential area of ​​the upper flow guide rib 11 (i.e., upper flow guide rib 11a) located in the inner ring. The lower flow guide rib 12 is arranged in two rings from the inside out (i.e., the aforementioned lower flow guide rib 12a and lower flow guide rib 12b). Based on this, the liquid flows out from the annular outlet 52 formed at the bottom of the inlet plate 50 and flows into the atomizing plate 10 from the annular inlet 51. The liquid is divided into two parts (i.e., diversion) at the opening 13. One part of the liquid flows to the upper guide rib 11a for the first atomization, and then flows to the upper guide rib 11b for the second atomization via the first spreading annular surface 111. The other part of the liquid flows to the lower guide rib 12a for the first atomization, and then flows to the lower guide rib 12b for the second atomization via the second spreading annular surface 121. Thus, when the liquid flow rate is large, the liquid is diverted through the opening 13 to prevent liquid blockage. The upper guide rib 11 and the lower guide rib 12 atomize the diverted liquid respectively to ensure atomization efficiency and effectively ensure the mist output of the atomizing plate 10, thereby ensuring the final atomization effect.

[0057] Referring to Figures 5 and 10, the arrangement density of the upper guide ribs 11 in the inner ring is less than that in the outer ring, and the upper guide grooves 112 formed by two adjacent upper guide ribs 11 gradually expand from the inside to the outside. Taking the arrangement shown in Figure 10 as an example, the arrangement density of the upper guide ribs 11a is less than that of the upper guide ribs 11b. An upper guide groove 112a is formed between two adjacent upper guide ribs 11a, and an upper guide groove 112b is formed between two adjacent upper guide ribs 11b. The liquid reaches a first velocity a1 when passing through the upper guide channel 112a and a second velocity a2 when passing through the upper guide channel 112b. Since the arrangement density of the upper guide ribs 11a is less than that of the upper guide ribs 11b, that is, the spacing of the upper guide channels 112a is greater than that of the upper guide channels 112b, the first velocity a1 is less than the second velocity a2. Based on this, the liquid is first uniformly distributed and its flow velocity is accelerated through the upper guide channel 112a, then uniformly distributed through the first spreading annular surface 111, and finally uniformly distributed through the upper guide channel 112b a third time, with the flow velocity being accelerated a second time. This causes the liquid to flow towards the edge of the disc 30 at a faster speed, where it is torn into smaller droplets by the air, thereby enhancing the atomization effect. Meanwhile, the ratio between the spacing between two adjacent upper guide ribs 11 in the inner ring and the spacing between two adjacent upper guide ribs 11 in the outer ring is greater than the fifth preset value. That is, the ratio between the diameter of the upper guide groove 112a and the diameter of the upper guide groove 112b is greater than or equal to the fifth preset value. The fifth preset value can be 1.5 or preferably 2.

[0058] Similarly, referring to Figures 6 and 11, the arrangement density of the lower guide ribs 12 in the inner ring is less than that in the outer ring, and the lower guide grooves 122 formed by two adjacent lower guide ribs 12 gradually expand from the inside to the outside. Taking the arrangement shown in Figure 11 as an example, the arrangement density of the lower guide ribs 12a is less than that of the lower guide ribs 12b. A lower guide groove 122a is formed between two adjacent lower guide ribs 12a, and a lower guide groove 122b is formed between two adjacent lower guide ribs 12b. The liquid reaches a first velocity b1 when passing through the lower guide channel 122a and a second velocity b2 when passing through the lower guide channel 122b. Since the arrangement density of the lower guide ribs 12a is less than that of the lower guide ribs 12b, that is, the spacing of the upper guide channels 122a is greater than that of the upper guide channels 122b, the first velocity b1 is less than the second velocity b2. Based on this, the liquid is first uniformly distributed and its flow velocity is accelerated through the upper guide channel 122a. Then, the liquid is uniformly distributed a second time through the second spreading annular surface 121. Finally, the liquid is uniformly distributed a third time through the upper guide channel 122b and its flow velocity is accelerated a second time. This causes the liquid to flow towards the edge of the disk 30 at a faster speed, thereby being torn into smaller droplets by the air to enhance the atomization effect. Meanwhile, the ratio between the spacing between two adjacent lower guide ribs 12 in the inner ring and the spacing between two adjacent lower guide ribs 12 in the outer ring is greater than or equal to the sixth preset value. That is, the ratio between the diameter of the lower guide groove 122a and the diameter of the lower guide groove 122b is greater than or equal to the sixth preset value. The fifth preset value can be 1.5 or preferably 2.

[0059] Referring to Figure 3, when the upper guide ribs 11 are arranged in at least two rings from the inside out, the annular top plate 40 covers at least the upper guide ribs 11 located in the innermost ring, and the upper guide ribs 11 are in contact with the annular top plate 40 or form a first gap (not shown). Referring to Figure 10, taking the arrangement shown in Figure 10 as an example, the annular top plate 40 at least covers the upper guide ribs 11a. That is, the annular top plate 40 can cover only the upper guide ribs 11a, in which case the upper guide ribs 11a are in contact with the annular top plate 40 or form a first gap; it can also cover both the upper guide ribs 11a and part of the upper guide ribs 11b, in which case the upper guide ribs 11a and part of the upper guide ribs 11b are in contact with the annular top plate 40 or form a first gap; it can also cover both the upper guide ribs 11a and the upper guide ribs 11b, in which case the upper guide ribs 11a and the upper guide ribs 11b are in contact with the annular top plate 40 or form a first gap. The annular top plate 40 acts as a shield for the liquid, preventing the liquid from flying out of the atomizing plate 10 without being atomized, reducing liquid waste, and improving the overall atomization effect of the atomizing plate 10. The first gap formed between the annular top plate 40 and the upper guide ribs 11 (upper guide ribs 11a and / or upper guide ribs 11b) can increase the flow rate of liquid towards the edge of the plate 30, thereby further improving the mist output of the atomizing plate 10. Similarly, as shown in Figure 4, the lower guide ribs 12 contact the annular bottom plate 15 or form a second gap (not shown), thereby increasing the flow rate of liquid towards the edge of the plate 30 through the second gap, thereby further improving the mist output of the atomizing plate 10.

[0060] As shown in Figure 10, multiple openings 13 are configured and evenly spaced around the pivot 16. A spoke 17 is formed between two adjacent openings 13. The surface contour of the opening 13 gradually expands from the inside to the outside to facilitate the flow of liquid from the opening 13 into the distribution cylinder 14. Of course, the opening 13 can also be rectangular, and this embodiment does not specifically limit this. The side contour of the opening 13 gradually expands from top to bottom longitudinally to prevent the liquid from flowing into the distribution cylinder 14 from escaping back to the upper guide rib 11 from the edge of the opening 13 and causing the liquid to become blocked at the opening 13. A blocking portion 171 is formed on the surface of the spoke 17 extending laterally above the opening 13 to block the liquid flowing into the atomizing disk 10 laterally, preventing the liquid from flowing into the distribution cylinder 14 from the opening 13, increasing the flow rate of liquid to the upper guide rib 11, and thus ensuring that the liquid can flow evenly to the upper guide rib 11 and the lower guide rib 12, and ensuring the final atomization effect.

[0061] As shown in Figure 10, the diameter d1 of the spoke 17 near the pivot 16 is greater than or equal to a first preset value (e.g., 1 mm), thereby ensuring a relatively large space between the openings 13 to improve the strength of the disc body 30. The diameter of the opening 13 at the same radial distance from the central axis of rotation A differs from the width of the spoke 17 by a second preset value. The same radial distance from the central axis of rotation A refers to the positions where the opening 13 and the spoke 17 are respectively cut by the same circle. For example, using circle O as an auxiliary line drawn from the center of the disc 30, two endpoints are formed on both sides of the opening 13 and the spokes 17, respectively. The distance d2 between the two endpoints formed by the opening 13 (i.e., points c1 and c2) and the distance d3 between the two endpoints formed by the spokes 17 (i.e., points c2 and c3) are less than or equal to a second preset value (e.g., 1 mm), or preferably 0, i.e., d2 = d3, to ensure that the liquid can flow evenly to the upper guide rib 11 and the lower guide rib 12, and to ensure the final atomization effect. The longitudinal thickness of the opening 13 is greater than or equal to a third preset value (e.g., 1 mm) to improve the strength of the opening 13, prevent the disc 30 from breaking, and extend the service life of the atomizing disc 10. The outlet spacing at the edges of two adjacent upper guide ribs 11 on the outermost ring (i.e., the distance d4 of the upper guide channel 112b away from the pivot 16) and the outlet spacing at the edges of two adjacent lower guide ribs 12 on the outermost ring (i.e., the distance d5 of the lower guide channel 122b away from the pivot 16) are both greater than or equal to a fourth preset value (e.g., 1 mm) to ensure liquid output and atomization effect. The spacing between the upper guide ribs 11 and the lower guide ribs 12 is greater than or equal to a seventh preset value (e.g., 1 mm) to avoid the problem of liquids generated by the atomization of the upper guide ribs 11 and the lower guide ribs 12 adhering together and causing the liquid particles to become larger, thereby ensuring the final atomization effect.
