[0018] The technical solution of the present utility model is described below with reference to the accompanying drawings and embodiments.

[0019] Example 1: Reference Figures 1 to 3 The rotor mounting structure of a liquid atomization device described in this embodiment includes a fixed base 1, which is installed in a mounting plate 2. A rotor 4 mounted on the fixed base 1 is rotated through a bearing 3. A runner 5 is fixed to the bottom of the rotor 4, and the runner 5 is a pulley. A spray disc 6 is fixed to the top of the rotor 4, and the spray disc 6 is made of plastic. The spray disc 6 has an interference fit with the rotor 4, and the rotation of the rotor 4 can smoothly drive the spray disc 6 to rotate. A cover body 7 is provided at the bottom of the spray disc 6. The bottom of the cover body 7 extends downward. The top of the cover body 7 is sealed and the bottom is open. The bottom of the cover body 7 extends downward. The bottom of the cover body 7 is close to the top of the mounting plate 2, but does not contact the mounting plate 2. This can reduce the water mist that enters the bottom of the spray disc 6, thereby reducing the water mist from entering the bearing 3 and corroding the bearing 3.

[0020] Specifically, the cover body 7 is umbrella-shaped, and the cover body 7 only needs to not interfere with the fixing base 1 and the mounting plate 2. The spray disc 6 and the cover body 7 are integrally formed plastic parts, and both umbrella-shaped and cylindrical shapes are easy to achieve injection molding.

[0021] Specifically, the rotor 4 is provided with a groove 8 with a downward opening. The top of the fixed seat 1 is provided with a first tapered portion 9 that is loosely fitted with the groove 8. The upper portion of the first tapered portion 9 has a larger outer diameter than the lower portion. The upper portion of the first tapered portion 9 is close to the outer diameter of the groove 8, which effectively prevents water mist from entering the bearing 3. Furthermore, this structure allows water mist to liquefy into water during entry, forming a water film that effectively prevents water vapor from entering.

[0022] Specifically, a stepped hole 10 is provided on the inner wall of the lower part of the spray disc 6, and a second conical portion 11 is provided on the upper part of the fixing seat 1 to fit the stepped hole 10. The upper part of the second conical portion 11 has a large outer diameter and the lower part has a small outer diameter, which has the effect of preventing water mist from entering.

[0023] Specifically, the fixing base 1 is provided with an outwardly protruding mounting step 12, and an external thread 13 is provided above the mounting step 12. The mounting step 12 is located below the mounting plate 2. The nut 16 located above the mounting plate 2 installs the fixing base 1 on the mounting plate 2 through the external thread 13. The mounting plate 2 has a mounting hole (not shown in the figure). The fixing base 1 passes through the mounting hole from the bottom of the mounting plate 2 and is installed by screwing the nut 16 on the top of the mounting plate 2. A sealing ring is provided between the mounting step 12 and the nut 16 to prevent water mist from entering under the mounting plate 2.

[0024] Specifically, a plurality of radial grooves are provided on the circumference of the outer edge of the spray disc 6 to effectively guide the water mist to disperse.

[0025] Specifically, a bearing mounting hole 14 is provided in the fixing seat 1, and the bearings 3 are all installed in the bearing mounting hole 14. The bottom of the bearing mounting hole 14 is located below the mounting plate 2, which effectively prevents water vapor from entering the bearing 3. More than two bearings 3 are installed in the bearing mounting hole 14 above and below, and a spacer sleeve 15 is provided between the two bearings 3 to separate them.

[0026] The utility model provides a cover body 7 at the bottom of the spray disc 6, and the bottom of the cover body 7 extends downward, which effectively prevents water vapor from entering the bearing 3 from the bottom of the spray disc 6 and corroding the bearing 3. Through the stepped hole 10 of the spray disc 6 and the second tapered portion 11 matched therewith, a water film is formed on the outside of the second tapered portion 11, which effectively prevents water vapor from entering the bearing 3. Therefore, the service life of the bearing 3 is greatly extended.

[0027] When the utility model is working, the belt drives the rotor 4 to rotate at high speed through the rotating wheel 5, and the rotor 4 drives the spray disc 6 to rotate at high speed. The liquid falls into the top of the spray disc 6 and is instantly sprayed out to form water mist, which sprays the fabric or paper products.

[0028] Example 2: See Figure 4 Compared with embodiment 1, the difference is that the cover body 7 is in an umbrella-shaped cylindrical shape.
