Abstract

An atomizing disc, an atomizing device with the atomizing disc, and an unmanned aerial vehicle are provided. The atomizing disc includes: a bottom disc, an upper surface of the bottom disc being provided with a liquid inlet space; and a plurality of ribs, the plurality of ribs being disposed on the upper surface of the bottom disc and being spaced apart in a circumferential direction of the bottom disc. A centrifugal flow passage in communication with the liquid inlet space is defined between two adjacent ribs and the bottom disc. An end of a rib close to an edge of the bottom disc is provided with a first groove penetrating a side portion of the rib so as to cut fluid flowing through the centrifugal flow passage.

First claim

What is claimed is:

1. An atomizing disc, comprising:
a bottom disc, an upper surface of the bottom disc being provided with a liquid inlet space; and
a plurality of ribs, the plurality of ribs being disposed on the upper surface of the bottom disc and being spaced apart in a circumferential direction of the bottom disc, a centrifugal flow passage in communication with the liquid inlet space being defined between two adjacent ribs and the bottom disc, and an end, at an edge of the bottom disc, of each of the plurality of ribs being provided with a plurality of first grooves penetrating a side portion of the each of the plurality of ribs so as to cut fluid flowing through the centrifugal flow passage, wherein each of the plurality of first grooves is sequentially arranged in a thickness direction of a corresponding rib in the plurality of ribs, wherein each of the plurality of ribs is of arc-shape or linear, one end of the each of the plurality of ribs is located at the liquid inlet space, and the other end of the each of the plurality of ribs is located at the edge of the bottom disc.

2. The atomizing disc as claimed in claim 1 , wherein each of the plurality of ribs is of an arc shape, and each of the plurality of first grooves penetrates a side, away from a center of curvature of a rib corresponding to the each of the plurality of first grooves, of a corresponding rib in the plurality of ribs.

3. The atomizing disc as claimed in claim 2 , wherein each of the plurality of first grooves is arranged obliquely with respect to the bottom disc, and each of the plurality of first grooves gradually extends away from the bottom disc in a direction from a side of the respective first groove away from the center of curvature of the corresponding rib to a side of the respective first groove close to the center of curvature of the corresponding rib.

4. The atomizing disc as claimed in claim 1 , wherein each of the plurality of ribs is linear.

5. The atomizing disc as claimed in claim 4 , wherein each of the plurality of first grooves is arranged obliquely with respect to the bottom disc.

6. The atomizing disc as claimed in claim 1 , wherein the each of the plurality of ribs is of an arc shape, each of the plurality of first grooves is disposed obliquely with respect to the bottom disc, and each of the plurality of first grooves extends away from the bottom disc in a direction from a side of the respective first groove away from a center of curvature of the corresponding rib to a side of the respective first groove closer to the center of curvature of the corresponding rib, an opening of an end, closer to the bottom disc, of each of the plurality of first grooves, is smaller than an opening, away from the bottom disc, of the each of the plurality of first grooves.

7. The atomizing disc as claimed in claim 6 , wherein each of the first grooves comprises a first wall and a second wall opposite to each other, the first wall and the second wall are adjacent to the end of the corresponding rib with the respective first groove, the second wall is closer to the upper surface of the bottom disc with respect to the first wall, and the second wall extends away from a center of the bottom disc and toward the upper surface of the bottom disc.

8. The atomizing disc as claimed in claim 7 , wherein the first wall and the second wall are both arc-shaped walls or planar walls.

9. The atomizing disc as claimed in claim 1 , wherein each of the plurality of first grooves on the plurality of ribs penetrates two opposite sides of a corresponding rib in the plurality of ribs.

10. The atomizing disc as claimed in claim 1 , wherein an outlet end of the centrifugal flow passage is provided with a plurality of second grooves, wherein the plurality of second grooves are sequentially arranged in the circumferential direction of the bottom disc, and each of the plurality of second grooves penetrates the bottom disc to cut fluid flowing through the centrifugal flow passage in an axial direction of the bottom disc.

11. The atomizing disc as claimed in claim 10 , wherein an opening of each of the plurality of second grooves is gradually increased in a direction away from the liquid inlet space.

12. The atomizing disc as claimed in claim 10 , wherein each of the plurality of second grooves is a V-shaped groove comprising two groove walls, and the two groove walls of the second groove are both arc-shaped groove walls or planar groove walls.

13. The atomizing disc as claimed in claim 1 , further comprising a cover body, the cover body cooperating with the bottom disc to cover a plurality of centrifugal flow passages, the cover body being provided with a liquid inlet port facing the liquid inlet space.

14. The atomizing disc as claimed in claim 1 , wherein each of the plurality of first grooves is a strip groove, and an extending direction of each of the plurality of first grooves is inclined to the upper surface of the bottom disc.

15. The atomizing disc as claimed in claim 14 , wherein each of the plurality of ribs comprises a first side wall and a second side wall opposite to each other, one end of each of the plurality of first grooves extends to the first side wall, and the other end of each of the plurality of first grooves extends to the second side wall, a notch of each of the plurality of first grooves being disposed away from the liquid inlet space.

16. The atomizing disc as claimed in claim 14 , wherein an opening of each of the plurality of first grooves is gradually increased in a direction away from the upper surface of the bottom disc.

17. An atomizing device, comprising:
an atomizing disc as claimed in claim 1 ; and
a driving motor, a motor shaft of the driving motor cooperating with the atomizing disc to drive the atomizing disc to rotate.

18. An unmanned aerial vehicle, comprising an atomizing device as claimed in claim 17 .
