[0031] For the above-mentioned mounting part 12, see Figure 2 The mounting member 12 includes a surrounding wall portion 121, a mounting portion 122 and a fixing strip 123. The surrounding wall portion 121 is provided with a through cavity 121a, the fan member 11 is located in the through cavity 121a, one end of the fixing strip 123 is connected to the wall surface of the through cavity 121a, the fan member 11 is mounted on the other end of the fixing strip 123, and the mounting portion 122 is connected to one end of the surrounding wall portion 121 away from the fixing strip 123. When the fan member 11 pushes the gas to flow, the gas flows from the cavity opening of the through cavity 121a to the other cavity opening. The surrounding wall portion 121 plays a role in protecting the fan member 11, and the through cavity 121a of the surrounding wall portion 121 plays a role in guiding the wind.

[0032] Regarding the above-mentioned mounting portion 122 , the mounting portion 122 is provided with a mounting through hole 122 a , and the mounting through hole 122 a extends along the depth direction of the through cavity 121 a .

[0033] For the above-mentioned air guide cover 20, please refer to Figure 1 The air guide cover 20 includes a cover body 21 and a buckle portion 22. One end of the buckle portion 22 is connected to the cover body 21, and the other end of the buckle portion 22 is buckled and inserted into the mounting through hole 122a, so that the air guide cover 20 is locked to the fan assembly 10.

[0034] For the above-mentioned cover body 21, please refer to Figure 1 The cover body 21 is roughly trumpet-shaped, and the cover body 21 is provided with a cover cavity 21a, a first air guide port 21b and a second air guide port 21c. The first air guide port 21b and the second air guide port 21c are relatively arranged at two ends of the cover cavity 21a, and the first air guide port 21b and the second air guide port 21c both connect the outside with the cover cavity 21a.

[0035] For the above-mentioned buckling part 22, please refer to Figure 2-Figure 4The buckle part 22 includes a first buckle arm 221 and a second buckle arm 222. One end of the first buckle arm 221 and one end of the second buckle arm 222 are both fixed to the cover body 21, and the first buckle arm 221 and the second buckle arm 222 are arranged relatively spaced apart, and the first buckle arm 221 and the second buckle arm 222 are used to be inserted into the installation through hole 122a, so that the buckle part 22 is buckled and connected to the fan assembly 10, so that the air guide cover 20 can be quickly installed on the fan assembly 10. There is a deformation space between the first buckle arm 221 and the second buckle arm 222. When the air guide cover 20 is disassembled, the first buckle arm 221 and the second buckle arm 222 are pressed respectively to make the first buckle arm 221 and the second buckle arm 222 move toward each other, and the first buckle arm 221 generates an elastic force in a direction away from the second buckle arm 222, and the second buckle arm 222 generates an elastic force in a direction away from the first buckle arm 221. When the circumscribed circle of the first buckle arm 221 and the second buckle arm 222 is smaller than the diameter of the installation through hole 122a, the buckle part 22 can be separated from the installation through hole 122a, so that the air guide cover 20 is disassembled relative to the fan assembly 10. When the first buckle arm 221 and the second buckle arm 222 lose external force, the first buckle arm 221 and the second buckle arm 222 are reset by the elastic force of the first buckle arm 221 and the elastic force of the second buckle arm 222. Preferably, the first buckle arm 221 and the second buckle arm 222 are made of elastic materials, such as plastic.

[0036] For the first buckle arm 221, please refer to Figure 4 The first buckle arm 221 includes a first arm body 2211 and a first limiting protrusion 2212. One end of the first arm body 2211 is fixed to the cover body 21, and the first limiting protrusion 2212 is fixed to the other end of the first arm body 2211. Along the direction perpendicular to the insertion of the buckle portion 22 in the mounting through hole 122a, the width of the first limiting protrusion 2212 is greater than the width of the first arm body 2211. When the first buckle arm 221 and the second buckle arm 222 are used to be inserted in the mounting through hole 122a, the first arm body 2211 is located in the mounting through hole 122a, and the first limiting protrusion 2212 abuts against the surface of the mounting portion 122 away from the cover body 21.

[0037] In some embodiments, see Figure 3 Combination Figure 4, the first arm 2211 is coated with a first limiting convex layer 2214, and the first limiting convex layer 2214 is spaced apart from the first limiting convex portion 2212. In the direction perpendicular to the snap-fit ​​portion 22 plugged into the mounting through hole 122a, the width of the first limiting convex layer 2214 is greater than the width of the first arm 2211, so that the first limiting convex layer 2214 and the first limiting convex portion 2212 can limit the cover body 21 from moving along the plug-in direction or moving away from the plug-in direction. It can be understood that the first arm 2211 exposed between the first limiting convex layer 2214 and the first limiting convex portion 2212 corresponds to the mounting through hole 122a. In some embodiments, the distance between the first limiting convex layer 2214 and the first limiting convex portion 2212 is greater than the depth of the mounting through hole 122a, thereby increasing the error tolerance of the air guide cover 20 for installing the fan assembly 10.

[0038] For the first limiting protrusion 2212, please refer to Figure 4 The surface of the first position-limiting protrusion 2212 facing away from the first buckle arm 221 is provided with a first guide structure 2213, and the first guide structure 2213 is used to guide the first position-limiting protrusion 2212 to pass through the installation through hole 122a. Preferably, the first guide structure 2213 is an arcuate surface, and the vertical distance between the arcuate surface and the second buckle arm 222 gradually decreases from one end of the first arm body 2211 to the other end. When the air guide cover 20 is installed on the fan assembly 10, the first guide structure 2213 plays a guiding role, so that the air guide cover 20 can be installed on the fan assembly 10 quickly, further improving production efficiency.

[0039] For the second buckle arm 222, please refer to Figure 4 The second buckle arm 222 includes a second arm body 2221 and a second limiting protrusion 2222.

The second arm body 2221 and the first arm body 2211 are arranged relatively spaced apart, and the first limiting protrusion 2212 and the second limiting protrusion 2222 are arranged relatively spaced apart. Along the direction perpendicular to the insertion of the buckle part 22 into the mounting through hole 122a, the width of the second limiting protrusion 2222 is greater than the width of the second arm body 2221. When the first buckle arm 221 and the second buckle arm 222 are used to be inserted into the mounting through hole 122a, the second arm body 2221 is located in the mounting through hole 122a, and the second limiting protrusion 2222 abuts against the surface of the mounting part 122 away from the cover body 21.

[0040] In some embodiments, see Figure 3 Combination Figure 4The second arm 2221 is coated with a second limiting convex layer 2224, and the second limiting convex layer 2224 is spaced apart from the second limiting convex portion 2222. In a direction perpendicular to the snap-fit ​​portion 22 plugged into the mounting through hole 122a, the width of the second limiting convex layer 2224 is greater than the width of the second arm 2221, so that the second limiting convex layer 2224 and the second limiting convex portion 2222 can limit the cover body 21 from moving along the plug-in direction or moving away from the plug-in direction. It can be understood that the second arm 2221 exposed between the second limiting convex layer 2224 and the second limiting convex portion 2222 corresponds to the mounting through hole 122a. In some embodiments, the distance between the second limiting convex layer 2224 and the second limiting convex portion 2222 is greater than the depth of the mounting through hole 122a, thereby increasing the error tolerance of the air guide cover 20 for installing the fan assembly 10.

[0041] For the second limiting protrusion 2222, please refer to Figure 4 The second guide structure 2223 is provided on the surface of the second limiting protrusion 2222 away from the second buckle arm 222, and the second guide structure 2223 is used to guide the second limiting protrusion 2222 to pass through the installation through hole 122a. Preferably, the second guide structure 2223 is an arcuate surface, and the vertical distance between the arcuate surface and the first buckle arm 221 gradually decreases from one end of the second arm body 2221 to the other end. When the air guide cover 20 is installed on the fan assembly 10, the second guide structure 2223 plays a guiding role, so that the air guide cover 20 can be installed on the fan assembly 10 quickly, further improving production efficiency.

[0042] In some embodiments, there are two mounting portions 122 and two buckling portions 22, the two mounting portions 122 are arranged opposite to each other, and one buckling portion 22 is inserted into the mounting through hole 122a of the other mounting portion 122.
