In some embodiments, the waterproof ventilation assembly further includes a blocking member 200, the blocking member 200 is connected to a surface of the second sidewall 120 facing away from the first cavity 150, the blocking member 200 is provided with a plurality of uniformly distributed first through holes 210, an area of the first through holes 210 is smaller than an area of the second openings 125, and the second openings 125 correspond to the plurality of first through holes 210. When the liquid flows into the second cavity 640 from the first through hole 210 provided on the barrier 200, the flow rate of the liquid may be further reduced due to the barrier of the barrier 200, so that the liquid may substantially slide down only along the barrier 200 without affecting the use of the electricity meter.
Referring to fig. 2 to 4, in some embodiments, the waterproof ventilation assembly further includes a dust screen 300 and a connector 600, the dust screen 300 is provided with a plurality of uniformly distributed second through holes 310, the connector 600 has a set thickness, the connector 600 includes a first connection portion 610, a second connection portion 620 and two third connection portions 630, the first connection portion 610 and the second connection portion 620 are spaced apart along a height direction of the case 100, the two third connection portions 630 are spaced apart along a length direction of the case 100, the first connection portion 610 is located under the second connection portion 620, one end of the connector 600 is connected to a side of the second side wall 120 facing away from the first cavity 150 in a thickness direction of the connector 600, the dust screen 300 is connected to the other end of the connector 600, a second cavity 640 is defined between the dust screen 300, the connector 600 and the second side wall 120, the first connection portion 610 is provided with a third through hole 614, and the third through hole 614 communicates with the second cavity 640 and an external space. The dust-proof net 300, the connecting member 600 and the blocking member 200 form a second waterproof barrier, if the liquid can enter the second cavity 640 through the second opening 125, the liquid will naturally incline upwards to contact the inner wall of the second protrusion 122, and when the liquid flows into the second cavity 640 through the first through hole 210 provided on the blocking member 200, the flow rate of the liquid will be further reduced due to the blocking of the blocking member 200, so that the liquid can basically only slide down the blocking member 200 and be discharged out of the second cavity 640 through the third through hole 614 provided on the first connecting portion 610, without contacting the dust-proof net 300.
Referring to fig. 3 and 5, in some embodiments, the case 100 has a set length, the first connection portion 610 is provided with a plurality of drainage grooves 611 and a plurality of third through holes 614, each drainage groove 611 corresponds to each third through hole 614 one by one, and the third through holes 614 communicate the drainage grooves 611 with an external space. The drain groove 611 is capable of collecting the liquid flowing into the second chamber 640 and discharging through the third through hole 614.
Specifically, the side of the first connection portion 610 facing the second cavity 640 is provided with a bottom surface 612 and a plurality of guide surfaces 613, one end of each guide surface 613 is connected to the bottom surface 612, the other end of each guide surface 613 extends obliquely upward, the third through hole 614 is formed in the bottom surface 612, and the cross-sectional area of the drainage channel 611 is gradually smaller along the up-down direction, so that the drainage channel 611 can collect a larger range of liquid and drain the liquid from the third through hole 614, and the guide surfaces 613 can guide the liquid to flow to the third through hole 614 to avoid accumulation and retention of the liquid at the bottom of the second cavity 640.
In some embodiments, the barrier 200 selects a mesh of between 250 mesh and 300 mesh. On the one hand, the barrier 200 adopts the metal mesh with the mesh number of 250-300 meshes, so that the ventilation effect is met, and meanwhile, the surface tension exists between the liquid and the surface of the barrier 200, so that the liquid can be effectively prevented from entering further; on the other hand, after the liquid falls on the first through holes 210 formed in the metal mesh, the liquid and the surface tension between the metal mesh form a water film, the water film seals the first through holes 210, the liquid subsequently falling on the surface of the metal mesh presents spherical water drops, and under the action of gravity, the spherical water drops slide along the metal mesh surface and fall into the drainage groove 611, and are discharged through the third through holes 614. The above measures can ensure that the liquid does not directly enter the electric meter box 500 after the first waterproof measure fails, and the global and subversion product waterproof failure can not be caused.
