Referring to fig. 1 and 2, there is shown a ventilation cap for a filter breather pipe, comprising a gas-water separation sleeve 1, a water deflector assembly 2 and a rain deflector assembly 3;
the gas-water separation sleeve 1 comprises a pipe body 11 sleeved on the vent pipe body 100 and a drainage plate 12 arranged in the pipe body 11, wherein the drainage plate 12 is provided with a through hole for the vent pipe body 100 to penetrate through; the water blocking assembly 2 comprises a first baffle 3121 and a first support member 22, wherein the first baffle 3121 is arranged in the steam-water separation sleeve pipe, the first baffle 3121 is positioned above the port of the vent pipe body 100, and the first support member 22 is used for supporting the first baffle 3121 so as to fix the position thereof; the rain shielding assembly 3 comprises a second baffle and a second supporting piece 32, wherein the second baffle is arranged above the steam-water separation sleeve, and the second supporting piece 32 is used for supporting the second baffle so as to fix the position of the second baffle.
Specifically, when the gas and the clean water are sprayed out of the vent pipe body 100, the first baffle 3121 located above the port of the vent pipe body 100 blocks the clean water, and the clean water is sprayed to the side under the condition that the first baffle 3121 blocks the clean water, so that the clean water is sprayed to the inner wall of the pipe body 11, and then flows downwards along the inner wall of the pipe body 11 and flows along the drainage plate 12 to re-flow into the vent pipe body 100, so that the waste of water resources is prevented; at the same time, gas can pass through the gap between the gas-water separation sleeve 1 and the first baffle 3121 and leave from the top end of the gas-water separation sleeve 1; the second baffle of the rain shielding assembly 3 can be shielded above the top end of the gas-water separation sleeve 1, and can prevent rainwater from entering the gas-water separation sleeve 1 and polluting clean water due to the fact that the rainwater enters the vent pipe.
In this embodiment, referring to fig. 1 and 2, a filter screen 4 is disposed at the top end of the tube 11, and foreign matters such as leaves and mosquitoes are prevented from entering the gas-water separation sleeve 1 from the outside by the filter screen 4.
In this embodiment, the first supporting member 22 is a steel bar, one end of the first supporting member 22 is welded to the first baffle 3121, and the other end is welded to the port of the vent pipe body 100. In addition, the pipe body 11 and the drainage plate 12 are both made of steel plates, the outer edge of the drainage plate 12 is welded with the pipe body 11, and the inner edge of the through hole of the drainage plate 12 is welded with the vent pipe body 100.
