[0026] Embodiment:

[0027] See Figure 1 and Figure 2 , this embodiment provides a flat panel, including a profile frame 1, a light filtering strip 2, a display screen 3 and a circuit board 4.

[0028] Among them, the profile frame 1 includes a body, a bottom plate 11, a first side plate 12 and a second side plate 14. A circuit groove 15 is provided on the body, the circuit board 4 is installed in the circuit groove 15, and an infrared emitter is installed on the circuit board 4, and the infrared emitter is arranged facing the opening of the circuit groove 15.

[0029] The second side plate 14 and the first side plate 12 are arranged oppositely. Both the second side plate 14 and the first side plate 12 form a certain angle with the horizontal plane. For example, in this embodiment, both the second side plate 14 and the first side plate 12 are perpendicular to the horizontal plane. Among them, the top of the first side plate 12 is higher than the top of the second side plate 14. Both the second side plate 14 and the first side plate 12 are located at the opening of the circuit groove 15.

[0030] The bottom plate 11 is horizontally arranged on the body, and the bottom end of the first side plate 12 is arranged on the upper surface of the bottom plate 11. Thus, the first side plate 12 and the bottom plate 11 enclose a drainage groove 13. The display screen 3 is perpendicular to the horizontal plane, and the display screen 3 is installed at the drainage groove 13 so that the bottom edge of the display screen 3 is located within the drainage groove 13. The second side plate 14 is located on the side of the first side plate 12 away from the display screen 3. The side of the display screen 3 facing the first side plate 12 is the front of the display screen 3, and the side of the display screen 3 facing away from the first side plate 12 is the back of the display screen 3. The front of the display screen 3 and the first side plate 12 are arranged at intervals, and the gap between the front of the display screen 3 and the first side plate 12 can allow water flow to enter the drainage groove 13.

[0031] The light filtering strip 2 is inclined relative to the bottom plate 11. In the direction from the top edge of the light filtering strip 2 to the bottom edge of the light filtering strip 2, the light filtering strip 2 gradually moves away from the display screen 3. The top of the light filtering strip 2 is provided with a first card slot 21, and the bottom of the light filtering strip 2 is provided with a second card slot 22. The top end of the first side plate 12 is clamped at the first card slot 21, and the top end of the second side plate 14 is clamped at the second card slot 22. Thus, the light filtering strip 2 is positioned and supported on the profile frame 1, and at the same time, the light filtering strip 2 also blocks the opening of the circuit groove 15.

[0032] Among them, the top end of the first side plate 12 has a first water blocking surface 121, and the first water blocking surface 121 is inclined relative to the bottom plate 11. In the direction from the bottom edge of the first water blocking surface 121 to the top edge of the first water blocking surface 121, the first water blocking surface 121 gradually moves away from the display screen 3. The top of the second side plate 14 has a second water blocking surface 141, and the second water blocking surface 141 is inclined relative to the bottom plate 11. In the direction from the top edge of the second water blocking surface 141 to the bottom edge of the second water blocking surface 141, the second water blocking surface 141 gradually moves away from the display screen 3. Due to the action of gravity, it is difficult for water flow to flow from the bottom edge of the first water blocking surface 121 to the top edge of the first water blocking surface 121, and it is also difficult for water flow to flow from the bottom edge of the second water blocking surface 141 to the top edge of the second water blocking surface 141.

[0033] It is particularly noteworthy that the top edge of the first water blocking surface 121 is located within the first card slot 21, and the top edge of the second water blocking surface 141 is located within the second card slot 22 to ensure that the top edges of the first water blocking surface 121 and the second water blocking surface 141 can be blocked by the light filtering strip 2.

[0034] During the process of wiping and cleaning the front surface of the display screen 3, a part of the water flow can flow into the drainage trough 13 through the gap between the front surface of the display screen 3 and the first side plate 12. During this process, this part of the water flow will pass through the part of the first water blocking surface 121 that is not blocked by the first card slot 21, that is, the non-top edge part of the first water blocking surface 121. The water flow located on the non-top edge part of the first water blocking surface 121 is difficult to flow towards the top edge of the first water blocking surface 121 under the action of gravity, so it is difficult to reach between the first side plate 12 and the second side plate 14, and it is difficult to enter the circuit trough 15, thereby reducing the occurrence of short circuits in the circuit board 4.

[0035] In this embodiment, the bottom edge of the first water blocking surface 121 is located outside the first card slot 21, so the water flow between the front surface of the display screen 3 and the first side plate 12 can reach the bottom edge of the first water blocking surface 121.

[0036] During the process of wiping and cleaning the front surface of the display screen 3, another part of the water flow does not enter the drainage trough 13, but flushes onto the upper surface of the light filtering strip 2. Under the action of gravity, this part of the water flow flows along the upper surface of the light filtering strip 2 to the bottom end of the light filtering strip 2, and then flows to the non-top edge part of the second water blocking surface 141, such as the bottom edge of the second water blocking surface 141. Similarly, due to the action of gravity, this part of the water flow is difficult to flow towards the top edge of the second water blocking surface 141, so it is difficult to reach between the first side plate 12 and the second side plate 14, and it is difficult to enter the circuit trough 15, thereby reducing the occurrence of short circuits in the circuit board 4.

[0037] Preferably, the first water blocking surface 121 is attached to the side wall of the first card slot 21 to reduce the gap between the top end of the first side plate 12 and the side wall of the first card slot 21 and improve the sealing performance of the first card slot 21. Similarly, the second water blocking surface 141 is attached to the side wall of the second card slot 22 to reduce the gap between the top end of the second side plate 14 and the side wall of the second card slot 22 and improve the sealing performance of the second card slot 22. This can further reduce the possibility of water seepage in the circuit trough 15.

[0038] In this embodiment, the profile frame 1 further includes a waterproof edge 16. The waterproof edge 16 is also vertically arranged with respect to the horizontal plane. The bottom end of the waterproof edge 16 is arranged on the upper surface of the bottom plate 11 and is opposite to and spaced from the first side plate 12. The display screen 3 is located between the first side plate 12 and the waterproof edge 16. The waterproof edge 16 and the first side plate 12 cooperate to limit the flow direction of the water flow in the drainage trough 13.

[0039] Further preferably, the waterproof edge 16 and the display screen 3 are spaced apart, and the bottom plate 11 and the display screen 3 are spaced apart.

[0040] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0041] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
