Detailed implementation manners

[0026] The following further describes the present application in detail with reference to the Figures 1 - 3 accompanying drawings.

[0027] An embodiment of the present application discloses a double-inlet fan that can be installed in multiple directions. Referring to Figure 1 , the double-inlet fan that can be installed in multiple directions includes a fan body 1, an air deflector 3, and a mounting frame 2. In this embodiment, the air deflector 3 has a C-shaped structure, and the mounting frame 2 has a cuboid structure. The mounting frame 2 includes two side plates 21 and a plurality of connecting members 22 connected between the two side plates 21. The fan body 1 is rotatably installed between the two side plates 21. One end of the air deflector 3 is connected to a position of one of the corners of the two side plates 21, and the other end is connected to the middle section of the two side plates 21, forming an air outlet 4 of the fan body 1, and the air outlet 4 faces outside the two side plates 21. The connecting members 22 are respectively connected to positions close to the other three corners of the two side plates 21, so as to more stably fix the mounting frame 2.

[0028] The two side plates 21 serve as the support structure of the fan body 1, and the connecting members 22 are connected to the positions of the other three corners of the two side plates 21, playing a role in strengthening the structural stability. Through the connecting plate and the two side plates 21, the air outlet 4 of the fan body 1 can face upward or sideward, improving the flexibility and convenience during installation and enabling the fan to be installed in multiple directions.

[0029] Referring to Figure 2 , in some embodiments, the outer side surface of the connecting member 22 and the outer side surface of the side plate 21 are in the same plane. That is, when the fan is placed, both the connecting member 22 and the side plate 21 can provide support, so that the air outlet 4 of the fan body 1 can be more stably oriented sideward or upward.

[0030] In some embodiments, the cross-section of the connecting member 22 has an "L" shape structure. This enables the fan to be placed more stably in different directions.

[0031] In some embodiments, the fan body 1 includes a plurality of blades 11. A part of the blade 11 is recessed toward one side to form a first recess 5, and another part is recessed toward the other side to form a second recess 6, so that the blade 11 can improve the air outlet efficiency and reduce the noise at the same time.

[0032] Referring to Figure 3, in some embodiments, the fan body 1 further includes a rotating member 12, and the blades 11 are respectively connected to both sides of the rotating member 12, so that the blades 11 can be more stably fixed through the rotating member 12, and a firm connection is formed between the blades 11, and the areas of the blades 11 on both sides are controlled to better improve the efficiency.

[0033] In some embodiments, twelve blades 11 are provided on each side of the rotating member 12. Due to the arrangement of the first concave portion 5 and the second concave portion 6 of the blade 11, on the basis of fourteen blades 11 in the prior art, the number of blades in this application is reduced to twelve, which reduces energy consumption while ensuring efficiency.

[0034] Refer again to Figure 1 , in some embodiments, the two side plates 21 are provided with installation grooves 8, so that double air inlet can be formed from the installation grooves 8 and the air outlet 4. An installation member 9 is arranged on the installation groove 8. In this embodiment, the installation member 9 is buckled on the installation groove 8 and is screwed to the side plate 21. A rotating shaft 10 is passed through and fixed to the rotating member 12, and the rotating shaft 10 is rotatably connected to the installation member 9. The installation member 9 in this embodiment includes an installation portion 91 and a rotating portion 92. The installation portion 91 has an annular structure and is connected to the side plate 21. The rotating portion 92 is integrally formed on the installation portion 91. The rotating portion 92 is provided with a rotating groove 13, and the rotating shaft 10 is rotatably installed in the rotating groove 13. The rotating shaft 10 drives the blades 11 to rotate through the rotating member 12.

[0035] In some embodiments, the multi-directionally installable double-air-inlet fan further includes a motor 14. The motor 14 drives the fan body 1 to rotate. The motor 14 is connected to the two side plates 21 and is located on the side where the air outlet 4 of the fan body 1 faces. This embodiment further includes a fixing plate 15. The fixing plate 15 is screwed to the two side plates 21 and is located below the air outlet 4. The motor 14 is screwed to the fixing plate 15.

[0036] The implementation principle of a multi-directionally installable double-air-inlet fan according to an embodiment of the present application is as follows: The two side plates 21 serve as the support structure of the fan body 1, and the connecting members 22 are connected to the positions of the other three corners of the two side plates 21, playing a role in strengthening the structural stability. Through the connecting plate and the two side plates 21, the air outlet 4 of the fan body 1 can be directed upward or sideward, improving the flexibility and convenience during installation and enabling the fan to be installed in multiple directions.

[0037] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
