FIG. 2 is a schematic structural diagram of a centrifugal spray disk 200 according to an embodiment of the present invention; fig. 3 is a schematic structural diagram of the spray disk body 300 in a first viewing angle according to the embodiment of the present invention.

Referring to fig. 2 and 3, the centrifugal spray disk 200 of the present embodiment includes a spray disk body 300 and a plurality of atomizing teeth 400, the spray disk body 300 can rotate around its central axis a, the spray disk body 300 has liquid injection regions 310 distributed around the central axis a and a spray region 320 surrounding the outer periphery of the liquid injection regions 310, the liquid injection regions 310 are used for receiving liquid, and the liquid flows into the spray region 320 when the spray disk body 300 rotates around the central axis a; the atomizing teeth 400 are rotatably disposed on the spray plate body 300, and the atomizing teeth 400 are disposed in the spraying area 320 at intervals along the circumferential direction of the spray plate body 300, and an atomizing channel 410 for the liquid entering the spraying area 320 to flow is formed between two adjacent atomizing teeth 400.

The centrifugal spray disk 200 of the embodiment adjusts the angle of the atomizing teeth 400 by rotating the atomizing teeth 400 arranged on the spray disk body 300, so that when the centrifugal spray disk 200 rotates at different rotating speeds, the liquid thrown out from the atomizing channel 410 can obtain a better atomizing effect by using the atomizing teeth 400 with the adjusted angle; specifically, by adjusting the angle of the atomizing teeth 400, when the centrifugal spray disk 200 rotates at different rotating speeds and the liquid flowing into the spray disk body 300 moves rapidly on the spray disk body 300, the liquid can be ensured to more accurately impact the edges or tips of the atomizing teeth 400 at various rotating speeds, so that the liquid is scattered and spilled, and a better atomizing effect can be obtained; if the angle of the atomizing teeth 400 is not adjusted, under the condition that the rotating speed of the centrifugal spray disk 200 is changed, most of the liquid entering the spray disk body 300 may directly flow out from the atomizing channel 410 between the adjacent atomizing teeth 400, and will not impact the edges or tips of the atomizing teeth 400, and the liquid will not be scattered by the atomizing teeth 400, which will result in poor atomizing effect.

The spray plate body 300 of the present embodiment is a circular plate. Of course, in other embodiments, the spray disk body 300 may also be a rectangular disk, an elliptical disk, etc., and is not limited herein.

It should be noted that, the angle of the atomizing teeth 400 specifically means: the angle of deflection of the atomizer teeth 400 with respect to the radial direction of the spray disk body 300.

It should be noted that the central axis a of the spray disk body 300 is the rotation axis of the centrifugal spray disk 200.

Due to the arrangement, the atomizing channel 410 is formed between the tooth parts 420 of two adjacent atomizing teeth 400, and the angle of the tooth part 420 can be adjusted by rotating the connecting part 430 relative to the spray disk body 300, so that the tooth parts 420 can be adjusted to different angles when the centrifugal spray disk 200 rotates at different rotating speeds, and a better atomizing effect can be obtained; specifically, by adjusting the angle of the tooth 420, when the centrifugal spray disk 200 rotates at different rotation speeds and the liquid flowing into the spray disk body 300 moves rapidly on the spray disk body 300, the liquid can be ensured to more accurately impact the edge or the tip of the tooth 420 at various rotation speeds, so that the liquid is scattered and spilled, and a better atomization effect can be obtained; if the angles of the teeth 420 are not adjusted, most of the liquid entering the spray disk body 300 may directly flow out from the atomizing passages 410 between adjacent teeth 420 without colliding with the corners or tips of the teeth 420 under the condition that the rotation speed of the centrifugal spray disk 200 is changed, and the atomization effect is poor because the liquid cannot be scattered by the teeth 420.

In other embodiments, the centrifugal spray disk 200 further includes a driving motor, and an output shaft of the driving motor is in transmission connection with the atomizing teeth 400 for driving the atomizing teeth 400 to rotate relative to the spray disk body 300 so as to adjust the angle of the atomizing teeth 400. Alternatively, the output shaft of the drive motor may be in driving connection with one of the first rod 431 and the second rod 432.

Referring to fig. 5, further, the dial 520 extends along a radial direction of the dial body 510; with this arrangement, when the dial body 510 is rotated relative to the dial body 300, the paddle 520 can be displaced relative to the radial direction of the dial body 510, and thus the second lever 432, the first lever 431, and the teeth 420 can be reliably driven by the paddle 520 to rotate synchronously, so that the deflection angle of the teeth 420 relative to the radial direction of the dial body 300 can be reliably adjusted.

With this arrangement, the angles of the tooth portions 420 of the plurality of atomizing teeth 400 can be adjusted simultaneously when the dial body 510 is rotated relative to the spray disk body 300, to improve efficiency.

It should be noted that the plurality of dials 520 of the present embodiment each extend in a radial direction of the dial body 510 to form a radial distribution.
