[0025] See also Figure 1-Figure 2 The motor cover body 100 has heat dissipation holes 110 on its surface, and a dustproof plate 120 is connected to the heat dissipation holes 110. In a specific implementation, the heat dissipation holes 110 are provided on the surface of the motor cover body 100 to facilitate heat dissipation of the motor of the sprayer.

In a specific implementation, the cleaning member 230 is arranged inside the motor cover body 100, which is beneficial to the compactness between the components of the device.

The cleaning member 230 is used to clean the dust on the surface of the dustproof plate 120, and the dust will fall from the notch 130, thereby reducing the possibility of dust accumulation in the heat dissipation hole 110.

[0027] See also Figure 1-Figure 4The dustproof component 200 includes a motor 210 and a transmission member 220. The motor 210 is mounted on the upper surface of the motor cover body 100, and the output shaft of the motor 210 is connected to the transmission member 220.

The cleaning member 230 is in contact with the surface of the dustproof plate 120. In a specific implementation, by starting the motor 210, its output shaft drives the transmission member 220 to rotate, thereby driving the cleaning member 230 to rotate along the surface of the dustproof plate 120, which is beneficial to cleaning the dust attached to the surface of the dustproof plate 120, reducing the possibility that external dust is easily attached to the surface of the dustproof plate 120. Long-term accumulation will cause clogging of the dustproof plate 120, thereby causing the heat dissipation performance of the motor to decrease.

[0028] In this embodiment, a protective shell 140 is connected to the upper surface of the motor cover body 100, and a through hole is opened on the surface of the protective shell 140. The motor 210 is located in the protective shell 140. In a specific implementation, the motor 210 is arranged in the protective shell 140, which is beneficial to protecting the motor 210.

[0031] The embodiment of the utility model further provides a motor cover for a sprayer, including the above-mentioned dustproof structure and a motor body 300. One end of the motor body 300 is fixedly connected to the motor cover body 100. In a specific implementation, the motor cover body 100 is installed on the surface of the motor body 300, which is beneficial to the stability of the motor cover body 100 on the motor body 300.

[0032] Specifically, the working principle of the dustproof structure and the sprayer motor cover is as follows: when in use, the motor cover body 100 is installed at one end of the motor body 300, and the motor of the sprayer can be cooled through the heat dissipation holes 110. External dust will be blocked by the dustproof plate 120, reducing the possibility of dust entering the motor cover body 100 and contacting the motor body 300. By starting the motor 210, its output shaft drives the first bevel gear 211 to rotate, and the first bevel gear 211 will drive the second bevel gear 222 to rotate, and then drive the rotating rod 221 to rotate, so that the cleaning brush 232 on the surface of the cleaning block 231 can rotate along the surface of the dustproof plate 120, which is conducive to cleaning the dust attached to the surface of the dustproof plate 120, reducing the possibility of external dust attaching to the surface of the dustproof plate 120. Long-term accumulation will cause blockage of the dustproof plate 120, thereby causing the heat dissipation performance of the motor to decrease. Dust will fall from the notch 130, reducing the possibility of dust accumulation in the heat dissipation holes 110.

For those skilled in the art, the utility model can have various modifications and changes.
