[0047] According to the structure described above, by designing the branch air duct 2, air can be blown toward the driver's side, increasing the air outlet positions and further improving the driver's comfort.

[0048] Furthermore, preferably, there are two branch ducts 2, one at each end of the main duct 1, i.e., on either side of the driver. As can be seen, the two branch ducts 2 and the main duct 1 form a U-shaped duct structure, which can then surround the top and sides of the driver, increasing the number of air outlets, allowing air to blow around the driver, greatly improving driver comfort. Of course, this is not limited to the above. The number of branch ducts 2 can also be one, or even no branch ducts 2 can be provided, that is, only the main duct 1 can be used.

[0059] In this embodiment, preferably, the branch air duct 2 is made of plastic.

[0062] According to the structure described above, the defogger duct 6 is used to introduce the wind in the main air duct 1 into the windshield, and then the windshield can be defogged and defrosted by blowing air toward the windshield, ensuring that the driver can clearly see the outside world through the windshield, ensuring normal work and safety and reliability during driving.

[0063] In this embodiment, preferably, Figures 1 to 4 As shown, the defogger duct 6 is connected to the main air duct 1 by plugging, and a second sealing component is provided between the defogger duct 6 and the main air duct 1.

In addition, a first sealing component such as a sealing ring is provided between the defogger duct 6 and the main air duct 1 to further improve the sealing performance.

[0065] Of course, the connection method is not limited to the above-mentioned method, and other connection methods can also be used. For example, flanges are respectively provided at the joints of the defogger duct 6 and the main air duct 1, and the two flanges are connected to each other and can be detachably connected by bolts, etc., or the defogger duct 6 and the main air duct 1 are an integrated structure, or when the defogger duct 6 and the main air duct 1 are made of metal, they can be connected by welding. The specific selection depends on actual needs.

[0066] In this embodiment, preferably, the defogger air duct 6 is made of plastic.

[0067] According to the structure described above, the defogger duct 6 made of plastic is light in weight, which contributes to lightweight design. Of course, it is not limited to this, and the material of the defogger duct 6 can also be selected according to actual needs.

[0068] In this embodiment, preferably, Figure 4 As shown, the defogger duct 6 is formed with a second connecting portion 62, and is detachably connected to a second target location, such as the inner wall of the cab, through the second connecting portion 62 and a second fastening member, such as a screw or a bolt.

[0071] According to the structure described above, the wind discharged from the evaporator of the air conditioner enters the main air duct 1 through the main air inlet 11 of the main air duct 1, and then flows along the main air duct 1 and blows toward the driver through the main air outlet 12. At the same time, the wind in the main air duct 1 is diverted to the branch air duct 2 and the defogger air duct 6, and after circulation, it passes through the branch air outlet 21 and the defogger air outlet 61 in turn and blows toward the driver and the front windshield.

[0072] Further, preferably, Figures 1 to 4As shown, the defogger duct 6 is arranged above the main air duct 1 and is located on the side of the aforementioned main air inlet 11. The overall layout is reasonable to avoid interference.

[0073] In this embodiment, preferably, Figures 1 to 3 As shown, along the direction from the air inlet of the main air duct 1 to its air outlet, the main air duct 1 is gradually expanding, which can quickly introduce the wind and divert it to the branch air ducts 2 on different sides.

Of course, it is not limited to this. The side of the main air duct 1 facing away from the main air inlet 11 can also be a planar structure, that is, along the direction of wind flow, the first main air duct 1 and the second main air duct are air ducts of equal thickness, rather than gradually expanding air ducts. The specific selection is based on actual needs.

[0075] And on the basis of the main air duct 1 having the aforementioned structure, branch air ducts 2 are provided on both sides of the main air duct 1. Of course, the structure of the main air duct 1 is not limited to the above, and other structures may also be adopted. For example, the main air duct 1 may only be half of the structure of the main air duct 1 in this embodiment, etc., and the specific selection is based on actual needs.

[0076] In this embodiment, preferably, the main air duct 1 is made of plastic.

[0077] According to the structure described above, the main air duct 1 made of plastic is light in weight, which is conducive to lightweight design. Of course, it is not limited to this, and the material of the main air duct 1 can also be selected according to actual needs.

Of course, the position of the main air duct 1 is not limited to the above, and can also be located in front of or above the driver, etc., according to actual needs.

[0081] In addition, when the main air duct 1 is arranged directly above the driver in the cab, the branch air duct 2 is located directly to the side of the driver. Of course, it is not limited to this, and can also be located in front of or behind the driver, depending on actual needs.
