As shown in fig. 1~4, the present invention in a first preferred embodiment provides an air duct structure, which includes a wind shell 100, a cut-off wall 200 and a base 500, wherein the wind shell 100 is preferably tubular and one end thereof is in a closed state, and has the advantages of high air tightness and convenient manufacturing.

The wind casing 100 is provided with an air inlet 110 and an air outlet 120, wherein the air inlet 110 and the air outlet 120 are adjacently arranged, that is, the air outlet 120 is arranged on the side wall of the wind casing 100; when in use, the air outlet 110 is connected to a fan, the fan sends air to the inside of the air casing 100 through the air outlet 110, and the air flows out through the air outlet 120, and the air outlet 120 is preferably in a long strip shape, so as to improve the coverage of the air flow.

Further, a plurality of the intercepting walls 200 are arranged at intervals on the air outlet 120 and extend to the inside of the wind casing 100, so as to divide the inside of the wind casing 100 and the air outlet 120 into a plurality of sections, it should be understood that the peripheries of the intercepting walls 200 are tightly attached to the inner wall of the wind casing 100, and the intercepting walls 200 at the ends are completely matched with the wind casing 100, so as to avoid that the edge of the air outlet 120 is too close to the edge of the wind casing 100, which affects the structural stability of the main casing 100; when the air flow enters the air casing 100 from the air inlet, the intercepting walls 200 intercept part of the air flow in sequence, so that the air output of the air outlet 120 can be uniform in the front, middle and back.

Preferably, as shown in fig. 3, the extension lengths of the cut-off walls 200 decrease in sequence along the air intake direction, specifically, the extension lengths of the cut-off walls 200 do not exceed the radius of the wind jacket 100, further, the extension lengths of the cut-off walls 200 are irregular, and the extension length of the cut-off wall 200 located upstream is greater than that of the cut-off wall 200 located downstream.

Further, as shown in fig. 3, the intercepting wall 200 is disposed to be inclined toward a side away from the air outlet 120 to correct the wind direction, so that the wind flow can flow out from the air outlet 120 vertically.

Further, as shown in fig. 3, the wind speed of the wind current is high in the front half of the wind housing 100, and therefore, the cutoff wall 200 positioned in the front half of the wind housing 100 is bent upward to buffer the wind speed in this region, thereby improving the stability when the wind current flows out.

Specifically, as shown in fig. 4, the wind cowl 100 includes an upper cover 130 and a bottom cover 140, the upper cover 130 and the bottom cover 140 are connected by a fastening structure 300 to form the wind inlet 110, the wind outlet 110 and the cut-off wall 200 are disposed on the upper cover 130, the fastening structure 300 is utilized to facilitate the dismounting and maintenance of the wind cowl 100, specifically, the fastening structure 300 includes a clip and a locking member, the clip is disposed on the outer side of the upper cover 130, the locking member is disposed on the outer side of the bottom cover 140 and corresponds to the clip, more specifically, a step and a convex wall are respectively disposed on the connection surface of the upper cover 130 and the bottom cover 140, the step and the convex wall are matched, which is beneficial to improve the sealing performance of the wind cowl 100.

Specifically, as shown in fig. 3 and 4, the rear half of the bottom cover 140 may be bent upward or horizontally, and is preferably bent upward in this embodiment to reduce the space of the rear half of the wind housing 100 and to direct the wind flow upward, so that the intercepting wall 200 located at the rear half of the wind housing 100 can intercept the wind flow sufficiently.

Specifically, as shown in fig. 1, 3 and 4, the base 500 includes a main body 510 and two reinforcing ribs 520, wherein the main body 510 is fixed on the main body of the electrical appliance through screws, the plurality of reinforcing ribs 520 are arranged side by side along the length direction of the main body 510, and are provided with two rows, the bottom cover 500 is connected with the reinforcing ribs 520, so that the stability of the bottom cover 500 can be improved, and the heat dissipation of the wind housing 100 is facilitated.

More specifically, a guide wall 400 vertically extends from an outer edge of the air outlet 120, and the guide wall 400 is convenient for subsequent alignment with the main body of the electrical appliance and can further guide the flowing air flow.

It should be noted that the air outlet 120, the cut-off wall 200, the upper cover 130 and the guide wall 400 are integrally formed; the bottom cover 500, the main body 510 and the reinforcing ribs 520 are integrally formed, so that the structural stability can be effectively improved, and the production processes can be reduced.

As shown in fig. 5 to 7, the present invention further provides a second embodiment, which is different from the first preferred embodiment of the present invention, in this embodiment, the extension length of the cut-off wall 200 is sequentially increased along the air inlet direction, wherein the difference of the extension length of the cut-off wall 200 is irregular, and the cut-off wall 200 is vertically disposed. The rear half of the bottom cover 140 in this embodiment is preferably horizontally disposed to ensure the air volume of the rear half of the wind case 100, and the structure is simpler and the production cost is lower.

And the air duct structure of the first preferred embodiment of the utility model is more uniform and reliable than the air output of the second embodiment.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
