Electronic device having blocking element

1. An electronic device, comprising:

an electronic module;

a casing, accommodating the electronic module; and

at least one air port, disposed on the casing to communicate the inside of the casing to the outside, the air port comprising:

a first inclined blocking element, having a plurality of first inclined openings, and the first inclined openings inclining relative to a horizontal direction; and

an appearance blocking element, disposed at a periphery of the first inclined blocking element in relation to the casing, and having a plurality of elongated aperture slots and a plurality of bending portions, wherein the elongated aperture slots are arranged in parallel, the bending portions are respectively disposed at the elongated aperture slots to interfere with a movement of airflow, and each of the bending portions extends inwards from a side of the corresponding elongated aperture slot and partially blocks an opening area of the corresponding elongated aperture slot, wherein each of the bending portions has a turning portion located in an inner space of the appearance blocking element.

2. The electronic device as recited in claim 1 , wherein a range of an inclination angle of the first inclined openings in relation to the horizontal direction is from 30 degrees to 75 degrees.

3. The electronic device as recited in claim 1 , wherein the air port further comprising:

a relay blocking element, having a plurality of square aperture slots, and the square aperture slots being arranged in an array, wherein the first inclined blocking element is disposed at a periphery of the relay blocking element in relation to the casing.

4. The electronic device as recited in claim 1 , wherein the air port further comprises a filter element, and the first inclined blocking element is disposed at a periphery of the filter element in relation to the casing.

5. The electronic device as recited in claim 4 , wherein the filter element comprises a foam.

6. The electronic device as recited in claim 1 , wherein the casing having a flow channel, the flow channel is located inside of the casing, and the air port is connected to the flow channel.

7. The electronic device as recited in claim 1 , wherein the casing having a flow channel, the flow channel is located inside of the casing, the number of the at least one air port is a plurality, and the air ports are respectively connected to the flow channel.

8. The electronic device as recited in claim 1 , further comprising:

an airflow driving element, disposed within the casing to drive airflow through the air port.

9. The electronic device as recited in claim 1 , further comprising a translucent plate disposed at the casing, wherein the electronic module comprises a display unit disposed within the casing and configured to produce an image, wherein the translucent plate is located on a transmission path of the image.

10. The electronic device as recited in claim 9 , wherein the translucent plate and the display unit constitute a flow channel, the flow channel is located inside of the casing, and the flow channel is communicated with the air port.

11. An electronic device, comprising:

an electronic module;

a casing, accommodating the electronic module; and

at least one air port, disposed on the casing to communicate the inside of the casing to the outside, the air port comprising:

a first inclined blocking element, having a plurality of first inclined openings, and the first inclined openings inclining relative to a horizontal direction; and

a second inclined blocking element, overlapping in arrangement with the first inclined blocking element and having a plurality of second inclined openings, wherein the first inclined openings and the second inclined openings are substantially parallel to and alternate with each other, and the first inclined openings are separated from the second inclined openings.
