Because the first breathable film 211 and the second breathable film 421 both play a role in ventilation and dust prevention, devices such as a breathable cap or a breathable tube can also be adopted, so that both the functions of ventilation and dust prevention and internal and external air pressure balance can be achieved.
In a possible embodiment, the external mask 1 comprises: a first outer mask 11 and a second outer mask 12;
the air inlet 41 is formed between the first outer mask 11 and the exhaust passage 4;
the first outer mask 11 and the second outer mask 12 are connected through the concave part 6;
the angle between the concave portion 6 and the first or second outer face mask 11, 12 is in the range 40 ° to 100 °.
In the present embodiment, in order to form a negative pressure smaller than the inside of the cavity 3 outside the inner concave portion 6, an angle between the inner concave portion 6 and the first outer mask 11 or the second outer mask 12 is set within a range of 40 ° to 100 °, thereby satisfying a condition that the pressure outside the inner concave portion 6 is smaller than the pressure inside the cavity 3. Wherein the specific included angle may be set to 90 °, 80 ° or 70 °.
Wherein, the concave portion 6 can be designed according to the position of the vehicle lamp, for example, when the vehicle lamp is a front vehicle lamp, the concave portion 6 can be arranged at a position close to the second outer mask 12; or other lamps such as tail or turn lights, etc. may be disposed inside, on the upper side or on the lower side of the outer cover 1, etc., as long as the air outlet passage 42 in the region of the concave portion 6 is sufficient to discharge the negative pressure region.
In a possible embodiment, referring to fig. 4, the lamp housing 2 is provided with a groove 22, and two ends of the external mask 1 are clamped into the groove 22 to realize the positioning of the external mask 1.
In this embodiment, when the outer mask 1 is mounted on the lamp housing 2, since it is difficult to mount the outer mask 1 by manually holding the outer mask 1, the outer mask 1 can be pre-positioned, and the outer mask 1 can be pre-positioned by inserting both ends of the outer mask 1 into the grooves 22, and thereafter, the outer mask 1 can be mounted without holding the outer mask 1 by a worker, which facilitates the mounting work of the worker.
Referring to fig. 4, a sealing plate 121 is disposed on the outer wall of the outer mask 1, and the sealing plate 121 abuts against one side of the opening edge of the groove 22, which is far away from the cavity 3, so as to seal a gap between the outer mask 1 and the groove 22.
The sealing plate 121 can seal the gap between the groove 22 and the outer cover 1, so that rainwater is prevented from permeating into the cavity 3 from the gap between the groove 22 and the outer cover 1, and short circuit of the vehicle lamp after contact with rainwater is avoided.
