Preferably, three rank ventilation block water barrier by two in 120 ° symmetrically the connected barriers that block water form, be arranged on
Housing cavity upper end, and barrier is blocked water away from center line 10mm distance punishment cloth 2 in the exhaust of three ranksDiameter through hole；Described three
Rank ventilation block water barrier thickness be 2mm, width 13mm.
Preferably, the length of the installation screw rod is that 20mm exocoels are M10 screw threads, and reach 10mm, inner cavity is
Through hole.
The invention has the advantages that：
1. the configuration of the present invention is simple, design is reasonable, and processing and fabricating is convenient and of low cost, small volume, good reliability are exempted from
It safeguards, it is highly practical.
2. the present invention is solving large volume class case kind equipment in summer high-temperature in use, prominent meet generates inside and outside heavy rain case
Negative pressure causes case negative pressure to absorb water, and destroys the electronic component of casing interior or is caused very greatly to the sealing of case kind equipment
Difficulty.The present invention can simply solve the negative pressure water suction hidden danger of large volume case kind equipment very much, and the present invention can also protect case
Kind equipment, during air transportation, because the case external and internal pressure variation caused by flying height, caused case class are set
Standby damage.
In conclusion the configuration of the present invention is simple, design is reasonable, and small, capacity is big, at low cost, is easily installed, and passes through
Labyrinth type waterproof vent valve is set, can effectively solve the negative pressure water absorption issue of case kind equipment and rapid equalisation case kind equipment
Inside and outside differential pressure, it is highly practical, convenient for promoting the use of.
