[0042] As Figure 5 and Figure 6 shown, the rotating top cover 3 is rotatably supported on the boss 21 and is provided with fan blades 31. The fan blades 31 are arranged facing the air outlet channel 200, so that when the air flow at the air outlet 10 is discharged from the air outlet channel 200, it can blow towards the fan blades 31 and drive the rotating top cover 3 to rotate around the boss 21

[0043] When the air purifier with the above technical solution works, the water in the water tank 2 evaporates upward to realize the humidification function. The air flow generated by the purifier main body 1 blows out from the air outlet 10, then blows towards the fan blades 31 after passing through the air outlet channel 200, and drives the rotating top cover 3 to rotate relative to the water tank 2. Compared with the existing fixed humidifying device, the rotation of the rotating top cover 3 makes the product more interesting and ornamental, which is beneficial to improving the user experience

[0044] Exemplarily, referring to Figure 6 shown, the fan blades 31 are integrally formed on the inner side of the rotating top cover 3.

[0048] Exemplarily, the thimble 32 can be needle-shaped, columnar, spherical, etc., and its structure mainly considers reducing the friction between itself and the boss 21.

[0049] In order to make the rotary top cover 3 rotate more stably around the boss 21, referring to Figure 5 and Figure 6 as shown, so as not to deviate from the preset position in the horizontal direction, a positioning groove 22 is provided at the top of the boss 21, and the rotary top cover 3 is provided with a positioning convex portion 33. The cross-sections of the positioning convex portion 33 and the positioning groove 22 are circular. The positioning convex portion 33 is partially arranged in the positioning groove 22, so that the rotary top cover 3 can rotate around the positioning groove 22 through the positioning convex portion 33 and is limited in the horizontal direction by the positioning groove 22; the thimble 32 is located at the center of the positioning convex portion 33 and is rotatably supported at the bottom of the positioning groove 22.

[0050] Exemplarily, referring to Figure 5 as shown, the top of the boss 21 is provided with an inclined surface that slopes downward toward the positioning groove 22 and forms a structure similar to a funnel, so as to facilitate the rotary top cover 3 to be quickly fitted inside the positioning groove 22 through the positioning convex portion 33.

[0051] In an embodiment where the air flow of the above-mentioned air outlet 10 can be blown out from the air outlet channel 200, referring to Figure 2 and Figure 5 as shown, the boss 21 is uniformly provided with first gratings 201, and the first gratings 201 are used to output the air flow of the air outlet channel 200.

[0052] Exemplarily, referring to Figure 2 and Figure 5 as shown, the first gratings 201 are arranged on both the top surface and the side surface of the boss 21 at the same time. The first gratings 201 on the top surface face the fan blade 31, and the air flow blown out through them drives the rotary top cover 3 to rotate.

[0053] In order to achieve a better positioning effect, referring to Figure 5 and Figure 6As shown, the rotating top cover 3 is provided with an outer cover 34 around the outer periphery of the fan blade 31, and the outer cover 34 covers the outer periphery of the boss 21. The outer cover 34 is provided with air flow holes 301, and the air flow holes 301 are used to output the air flow blown out from the air outlet passage 200.

[0054] Exemplarily, referring to Figure 5 As shown, the cross-section of the outer cover 34 is annular and is integrally formed around the outer periphery of the fan blade 31.

[0055] In one implementation of arranging the air flow holes 301 on the outer cover 34, referring to Figure 6 As shown, the outer cover 34 is evenly provided with second gratings 302, and the air flow holes 301 are formed between the second gratings 302. The air flow blown out from the air outlet passage 200 can be blown out between the second gratings 302.

[0056] In order to increase the humidification efficiency, referring to Figure 2 and Figure 5 As shown, the air purifier further includes a filter screen 4. The filter screen 4 is arranged in the cavity 20 of the water tank 2 so that it can contact the water in the cavity 20. The filter screen 4 is located between the air outlet passage 200 and the outer periphery of the fan blade 31, so that the air flow in the air outlet passage 200 can pass through the filter screen 4 after blowing towards the fan blade 31 and is output to the outside. During the output process, the water in the filter screen 4 can be evaporated faster, which is beneficial to improving the humidification efficiency.

[0057] Combining the above implementations can achieve a better humidification effect. Specifically, as follows, referring to Figure 2 and Figure 5 As shown, the boss 21 is evenly provided with first gratings 201, and the first gratings 201 are used to output the air flow of the air outlet passage 200; the rotating top cover 3 is provided with an outer cover 34 around the outer periphery of the fan blade 31, and the outer cover 34 covers the outer periphery of the boss 21.
