DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0033] In the following description, "left", "right", "front", "back", "up" and "down" are oriented in the perspective of a plan view.

[0034] Embodiment one: in some embodiments, referring to the drawings of the specification Figures 1-7 A light-weight atomization disc of a rotary atomizer, comprising an upper disc 1, further comprising a lower disc 2, an anti-deformation mechanism 3, a centrifugal mechanism 4 and an atomization mechanism 5, the top of the upper disc 1 is provided with a feed inlet, the middle of the lower disc 2 is fixedly connected with the centrifugal mechanism 4, the anti-deformation mechanism 3 is fixedly connected inside the upper disc 1 and the lower disc 2, and the atomization mechanism 5 is detachably connected between the upper disc 1 and the lower disc 2.

[0035] In use, the liquid to be atomized is introduced into the upper disc 1, and then the centrifugal mechanism 4 is turned on, the centrifugal mechanism 4 operates to drive the entire atomization disc to rotate, thereby driving the liquid to move outward along the centrifugal mechanism 4, and then the liquid is preliminarily broken by the centrifugal force and the internal resistance of the centrifugal mechanism 4, and then further atomized and sprayed by the atomization mechanism 5. During the entire rotary centrifugal atomization process of the atomization disc, the anti-deformation mechanism 3 increases the structural rigidity of the entire atomization disc to prevent deformation of the atomization disc caused by excessive rotating torque.

[0036] For example Figures 2 to 4As shown, the anti-deformation mechanism 3 includes an outer ring 301, a horizontal reinforcing rib 302, an inner ring 303, and a mounting assembly, two outer rings 301 are fixedly connected inside the upper disc 1 and the lower disc 2 respectively, two inner rings 303 are fixedly connected inside the upper disc 1 and the lower disc 2 respectively, and the outer ring 301 and the inner ring 303 are at the same horizontal position, a plurality of horizontal reinforcing ribs 302 are fixedly connected between the outer ring 301 and the inner ring 303, and the horizontal reinforcing ribs 302 are uniformly distributed at 360 degrees, and the outside of the mounting assembly is threadedly connected inside the two outer rings 301.

[0037] The mounting assembly includes a threaded reinforcing rib 304 and a fastening nut 305, the outside of the threaded reinforcing rib 304 is threadedly connected inside the two outer rings 301, the threaded reinforcing rib 304 is threadedly connected inside the upper disc 1 and the lower disc 2, and the bottom of the threaded reinforcing rib 304 is threadedly connected with the fastening nut 305.

[0038] When the atomizing disc as a whole rotates, the overall rigidity of the upper disc 1 and the lower disc 2 is ensured through the action of the outer ring 301 and the inner ring 303 to prevent the disc surface from being deformed in a wave shape during rotation, the horizontal reinforcing rib 302 resists the centrifugal force to prevent the disc body from expanding and deforming outward during high-speed rotation, and finally the threaded reinforcing rib 304 and the fastening nut 305 resist the stress of the entire disc in the vertical direction, thereby ensuring that the entire atomizing disc can maintain its structural stability during rotation to prevent deformation and damage of the atomizing disc due to excessive stress, and when the atomizing disc needs to be disassembled, the threaded reinforcing rib 304 and the fastening nut 305 are removed by rotating them, which can separate the upper disc 1 and the lower disc 2, and then facilitate the maintenance of the internal atomizing mechanism 5 and the centrifugal mechanism 4.

[0039] The centrifugal mechanism 4 includes a rotating shaft 401 and a centrifugal disc 403, the outside of the rotating shaft 401 is fixedly connected to the middle of the lower disc 2, the bottom of the rotating shaft 401 is provided with a motor docking interface 402, the top of the rotating shaft 401 is fixedly connected with the centrifugal disc 403, and the top of the centrifugal disc 403 is fixedly connected with a centrifugal flow channel 404.

[0040] The centrifugal flow channel 404 is circularly arrayed on the top of the centrifugal disc 403 to guide the liquid flow more smoothly and promote the breaking and atomization of the liquid.

[0041] The output end of the motor is docked with the motor docking interface 402 at the bottom of the rotating shaft 401, so that the power of the motor can drive the rotating shaft 401 to rotate, and the rotating shaft 401 drives the entire atomizing disc to rotate, when the atomizing disc rotates, the liquid on the top of the centrifugal disc 403 spreads outward due to the action of the centrifugal force and the guiding action of the centrifugal flow channel 404, and in the process of spreading, the liquid is broken into small droplets by the action of the centrifugal force and enters the subsequent atomizing mechanism 5.

[0042] The atomization mechanism 5 comprises a fixed ring 501, a stop block 503, a positioning assembly, and a homogenizing column 507. The inside of the fixed ring 501 is provided with a plurality of pressurized flow channels 502. The pressurized flow channels 502 are flush with the outside of the centrifugal disc 403 near the center of the lower disc 2. A plurality of stop blocks 503 are detachably connected between the upper disc 1 and the lower disc 2. The stop blocks 503 are fixedly connected with positioning assemblies on both the upper and lower sides. The stop blocks 503 are arranged in pairs, and a spraying channel 506 is formed between adjacent two stop blocks 503. The homogenizing column 507 is clamped between the spraying channel 506 and the pressurized flow channel 502.

[0043] The positioning assembly comprises a positioning block 504. The bottom of the upper disc 1 and the top of the lower disc 2 are both provided with a plurality of positioning grooves 505. The positioning block 504 is matched with the positioning grooves 505 in shape.

[0044] During the atomization process, the tiny liquid droplets after the initial fragmentation by centrifugation are further atomized by the pressurized flow channels 502 and enter the homogenizing column 507. The pressurized flow channels 502 are flush with the outside of the centrifugal disc 403 near the center of the lower disc 2, so as to reduce the liquid residue. The flow channels in the homogenizing column 507 have the same size, so that the atomized liquid droplets are uniformly distributed. Finally, the atomized liquid is sprayed through the spraying channel 506 formed between the two stop blocks 503 after homogenization. Since the liquid can cause a certain degree of wear to the stop blocks 503 during the spraying process, thereby affecting the subsequent atomization and spraying effect, the upper disc 1 and the lower disc 2 can be separated, the stop block 503 can be taken out from between the upper disc 1 and the lower disc 2, and the replacement stop block 503 can be precisely assembled to the original position of the stop block 503 through the clamping between the positioning grooves 505 and the positioning blocks 504, so as to avoid the position deviation of the stop block 503 during the replacement process, which causes the gap of the spraying channel 506 and affects the atomization and spraying effect.

[0045] Embodiment Two: In some embodiments, referring to the accompanying drawings of the specification Figure 3 , Figure 5 and Figure 7 , the shape of the centrifugal flow channel 404 can be curved, which can guide the liquid to flow more smoothly, reduce flow resistance and turbulence, and at the same time make the liquid receive forces in different directions in the flow channel, promote the fragmentation and atomization of the liquid.

[0046] Embodiment Three: In some embodiments, referring to the accompanying drawings of the specification Figure 2 and Figure 6 , the pressurized flow channel 502 has a large aperture near the center of the lower disc 2 and a small aperture away from the center of the lower disc 2. When the liquid flows from the large aperture to the small aperture, the high-speed flowing liquid and the surrounding air will produce strong interaction, the air will produce shear force on the liquid, the shear force will make the liquid surface produce unstable fluctuation, and then the liquid will be broken into small droplets, forming atomization, so as to further improve the atomization effect.

[0047] The spray channel 506 has a small aperture near one end of the center of the lower disc 2 and a large aperture far from the center of the lower disc 2, so as to reduce the resistance of the block 503 to the atomized liquid when the atomized liquid is sprayed, reduce wear and tear, and prolong the service life.

[0048] The block 503 is made of silicon nitride, which has the advantages of high hardness, wear resistance, high temperature resistance and light weight, so that the structure rigidity of the block 503 can be ensured and the wear degree caused by atomized spraying can be reduced when the rotating atomizing disc is working, and the weight of the whole atomizing disc is reduced.

[0049] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
