Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Referring to figs. 1 and 2, the utility model includes lid and waterproof ventilated membrane 10；There are two lids, and respectively
Lid I 1 for lid II 2 and for being sealedly connected on vessel port, lid I 1 and lid II 2 backwards to being arranged, lid I 1 and
The back side of lid II 2 offers blow vent；It is connected between the blow vent of lid I 1 and the blow vent of lid II 2 by straight tube 3,
Straight tube 3 is equipped with air gauge 5 and switch valve 4, and air gauge 5 is between switch valve 4 and lid I 1；The lid oral area of lid II 2
Thread seal is connected with film installation base plate 6, and film installation base plate 6 offers several air holes 9, is provided in each air hole 9
Waterproof ventilated membrane 10.
As a kind of technical solution of this patent selection, several assistant reinforcement bars are connected between lid I 1 and lid II 2
7, so that the structural strength of entire packing container ventilating cover is higher, it is hardly damaged.
As a kind of technical solution of this patent selection, the interior end side of film installation base plate 6 is provided with deflection cone 11, deflection cone
The blow vent of portion's face lid II 2 between 11 cone.If container air pressure inside value is larger, when turning on the switch valve 4, it is easy to anti-
Water ventilated membrane 10 causes certain impact, and for a long time in this way, can shorten the service life of waterproof ventilated membrane 10, and deflection cone 11 then may be used
Reduce impact of the gas shock to waterproof ventilated membrane 10.
As a kind of technical solution of this patent selection, the outer end side of film installation base plate 6 is provided with groove, the slot of the groove
