[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 6 As shown, this embodiment provides a packaging structure for a centrifugal fan. The centrifugal fan includes a fan body and a guide ring 13. The fan body includes a fan wheel 11 and a motor 12. The fan wheel 11 includes a wheel disc 111 and a wheel cover 112. The wheel disc 111 and the wheel cover 112 are connected by several fan blades 113. The wheel disc 111 is mounted on the motor 12. The packaging structure includes a carton body 2 and a carton cover 3. The carton cover 3 covers the carton body 2. The key feature is that the carton body 2 contains a positioning inner box 4. The fan wheel 11 is installed in the positioning inner box 4. The outer edge of the fan wheel 11 is tangent to the inner wall of the positioning inner box 4. The top of the positioning inner box 4 is provided with a box cover 41. The guide ring 13 is placed on the box cover 41. Several positioning blocks 31 protrude from the bottom of the carton cover 3. The positioning blocks 31 surround the guide ring 13. The bottom of the positioning blocks 31 presses on the box cover 41.

[0023] The packaging structure of the centrifugal fan described above is simple, lightweight, and easy to operate. The inner wall of the positioning inner box 4 is tangent to the outer edge of the impeller 11, which can effectively position the impeller 11 laterally. The box cover 41 separates the fan body and the air guide ring 13, preventing them from rubbing against each other. The positioning block 31 of the carton cover 3 is used to limit the air guide ring 13 and the fan body, preventing them from jumping up and down inside the box.

[0024] The positioning inner box 4 described above has a positioning through hole 42 at its bottom, and the end of the wheel cover 112 is engaged in the positioning through hole 42. The positioning through hole 42 can accurately position the fan body. The positioning inner box 4 is made of cardboard folded around the positioning through hole 42.

[0025] The aforementioned box cover 41 consists of two symmetrically arranged covers 41 with a gap 43 between them. The covers 41 press against the wheel 111, and the top of the motor 12 protrudes from the positioning inner box 4 through the gap 43 and is located inside the air guide ring 13. This saves space.

[0026] The aforementioned positioning block 31 is made of EPE material. EPE material is lightweight and inexpensive.

[0027] The outer wall of the cardboard box body 2 is provided with a "U"-shaped reinforcing strip 21, the top of the cardboard box lid 3 is provided with a first "U"-shaped reinforcing strip 32, and the bottom of the cardboard box body 2 is provided with a second "U"-shaped reinforcing strip 23. The "U"-shaped reinforcing strip 21, the first "U"-shaped reinforcing strip 32, and the second "U"-shaped reinforcing strip 23 can increase the strength of the cardboard box.

[0028] The cardboard box 2 described above has a pair of symmetrical handle holes 22 on its side wall. The handle holes 22 facilitate handling.

[0029] The aforementioned positioning inner box 4 is provided with a pair of first side panels 44 and a pair of second side panels 45. The folded edge 46 of the first side panel 44 overlaps the outer side of the second side panel 45, and the second side panel 45 is located inside the handle hole 22. A gap is formed between the second side panel 41 and the carton body 2, which further facilitates handling.

[0030] During packaging, first place the positioning inner box 4 into the carton body 2, then place the fan body into the positioning inner box 4, fold the box cover 41 over and close it, then place the air guide ring 13 in, and finally close the carton cover 3. The operation is convenient and quick.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
