The number of the first blocks 2 is at least two, and the first blocks 2 are provided at the air outlet and divide the air outlet into a plurality of sub-air outlets.

[0049] By adopting this structure, the wind coming in from the air inlet will be blown out from different sub-air outlets, and the first block 2 will guide and divert the wind. The number of first blocks 2 is at least two, and all the first blocks 2 are installed in the middle position of the air outlet. In this way, the number of sub-air outlets formed is at least three. Therefore, when the air duct structure provided in this embodiment is in use, it can realize a variety of different forms of air outlet states by connecting and disconnecting sub-air outlets with different arrangements and combinations. The air outlet volume and the range of the space covered by the air outlet can be adjusted in a wider range, and the entire air duct structure cleverly uses multiple first blocks 2. Under the premise of achieving effective air diversion, its structure is simpler, and the production cost and use cost are lower.

[0050] In order to facilitate installation, a screw hole 10 for passing a screw is further provided on the housing 1, and the screw hole 10 is a countersunk hole.

[0051] Embodiment 2:

[0052] This embodiment is further improved on the basis of embodiment 1. The air duct structure provided in this embodiment also includes a second block 6, which is arranged in the middle position of the above-mentioned air inlet to separate the air inlet into two sub-air inlets with the same flow rate. It is worth noting that the above-mentioned second block 6 is a conical block, and the cone tip of the second block 6 faces the inside of the air duct structure. The second block 6 is integrally formed with the shell 1 and the first block 2, and the first block 2, the second block 6 and the shell 1 are all structural parts made of foam. Specifically, the entire air duct structure is cast using a mold. The above-mentioned screw hole 10 is also provided on the second block 6.

[0053] There are two first blocks 2, which are symmetrically arranged at the air outlet, so as to divide the air outlet into three sub-air outlets with the same flow rate.

[0054] With the above structure, the air duct structure provided in this embodiment has two air inlets and three air outlets. The two air inlets have the same volume of gas passing through them per unit time, and the three air outlets have the same volume of gas passing through them per unit time. The user can choose to turn on and off different sub-air outlets as needed to obtain a variety of different air outlet states.

[0055] For ease of explanation, in this embodiment, the three sub-air outlets are divided into a first sub-air outlet 3, a second sub-air outlet 4 and a third sub-air outlet 5, and the air inlet is divided into a first sub-air inlet 7 and a second sub-air inlet 8.

[0056] First air outlet state: the first sub-air inlet 7 and the second sub-air inlet 8 are both connected, the first sub-air outlet 3, the second sub-air outlet 4 and the third sub-air outlet 5 are also all connected, at this time, the three sub-air outlets can discharge air;

[0057] Second air outlet state: the first sub-air inlet 7 and the second sub-air inlet 8 are both connected, the first sub-air outlet 3 and the second sub-air outlet 4 are connected, and the third sub-air outlet 5 is blocked and disconnected;

[0058] The third air outlet state: the first sub-air inlet 7 and the second sub-air inlet 8 are both connected, the first sub-air outlet 3 and the third sub-air outlet 5 are connected, and the second sub-air outlet 4 is blocked and disconnected;

[0059] Fourth air outlet state: the first sub-air inlet 7 and the second sub-air inlet 8 are both connected, the second sub-air outlet 4 and the third sub-air outlet 5 are connected, and the first sub-air outlet 3 is blocked and disconnected;

[0063] Since the first sub-air outlet 3, the second sub-air outlet 4 and the third sub-air outlet 5 are located at different positions, the air duct structure can provide seven kinds of air volume and air coverage, which is more practical. If equipped with blinds, the air coverage can be expanded.

[0064] Embodiment 3:

[0065] This embodiment is a better implementation of the above embodiment. In this embodiment, the side of the first block 2 close to the air inlet is defined as the windward surface 21. In the air duct structure provided in this embodiment, the windward surface 21 on the first block 2 is a curved surface inclined toward the shell 1, that is, the distance from the curved surface close to the side of the shell 1 to the air inlet is smaller than the distance from the curved surface away from the side of the shell 1 to the air inlet.

[0066] Through this structure, a smooth and uniform wind distribution effect can be obtained.

Specifically, the curved surface is composed of a first curved surface, a second curved surface and a third curved surface connected in sequence. The centers of the first curved surface and the third curved surface are both located on the side of the air outlet, and the center of the second curved surface is located on the side of the air inlet.

[0075] Moreover, a guide groove 9 is provided on the inner wall of the housing 1 at the air inlet, and the wind coming in from the sub-air inlet will flow toward the air outlet along the inner wall of the housing 1 at the air inlet. The provision of the guide groove 9 can reduce the resistance of the wind when it flows in the air duct structure, making the air inlet smoother, thereby making the air outlet more uniform. Specifically, the guide groove 9 is a U-shaped groove, and the opening of the U-shaped groove faces the air inlet.
