The shape of the first through hole 210 may be circular, rectangular, or oval, which is easy to manufacture, or may be hexagonal, pentagonal, or rhombic.
Further, the diameter of the first through hole 210 ranges from 0.5mm to 2mm. That is, the diameter of the through hole provided in the lid body 200 is small, and the through hole having a small diameter improves the deceleration effect of the air flow.
In an embodiment, as shown in fig. 2, an included angle between the surface of the cover body 200 between the first through hole 210 and the second through hole 220 and an axis of the first through hole 210 is a first included angle, and an included angle between the surface of the cover body 200 between the first through hole 210 and the second through hole 220 and an axis of the second through hole 220 is a second included angle, and both the first included angle and the second included angle are acute angles.
That is to say, the first through hole 210 and the second through hole 220 are oblique through holes relative to the surface of the cover body 200, and the first through hole 210 and the second through hole 220 are opposite to each other in an oblique manner, that is, the airflow flowing out from the first through hole 210 and the airflow flowing out from the second through hole 220 form an angle, and the airflow flowing out from the first through hole 210 and the airflow flowing out from the second through hole 220 partially meet and offset each other, so that the airflow at a distance from one end of the surface of the cover body 200 is dissipated, and when the airflow flows onto the body of a driver or a passenger, the airflow does not have a strong airflow feeling, and the comfort of the driver or the passenger is improved.
Further, the first included angle is the same as the second included angle. That is, the first through hole 210 and the second through hole 220 are arranged in a mirror image manner, so that the offset rate of the air flow flowing out of the first through hole 210 and the second through hole 220 is improved, and the intensity of the air flow flowing to the driver and the passenger is further reduced.
In an embodiment, as shown in fig. 3 and 4, the end cap 20 further includes a first flow guiding cover 230, the first flow guiding cover 230 is connected to the surface of the cover body 200 and located at an edge of the first through hole 210, and the first flow guiding cover 230 covers a partial area of the first through hole 210.

That is, by disposing the first deflector cap 230 and the second deflector cap 240 in front of the first through hole 210 and the second through hole 220, respectively, the direction of the air flow flowing out from the first through hole 210 and the second through hole 220 is changed, and the air flow flowing out from the first through hole 210 and the air flow flowing out from the second through hole 220 can meet and form partial cancellation, so as to reduce the speed of the air flow flowing to the body of the occupant.
Further, the included angle between the axis of the first through hole 210 and the surface of the cover body 200 is 90 °; the included angle between the axis of the second through hole 220 and the surface of the cover body 200 is 90 °.
That is, the axes of the first through hole 210 and the second through hole 220 are perpendicular to the surface of the cover 200, that is, the axes of the first through hole 210 and the second through hole 220 are parallel to the axis of the air duct 10, so as to improve the fluency of air flow discharge.
Alternatively, an angle exists between the axis of the first through hole 210 and the surface of the cover 200, and the angle increases the difficulty in manufacturing the cover 200 compared to the case where the axis of the first through hole 210 and the axis of the second through hole 220 are perpendicular to the surface of the cover 200.
In one embodiment, as shown in fig. 3, the cover 200 includes a first portion and a second portion, the first portion and the second portion are disposed adjacent to each other, the first through hole 210 is located on the first portion, the second through hole 220 is located on the second portion, and the first through hole 210 and the second through hole 220 are disposed opposite to each other.
