Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

The air compensating valve structure shown in fig. 1 to 3 comprises an electric air valve 1 with an air inlet 11 and an air outlet 12, and a rain shield pipe 2 with an air inlet 21 and an air outlet 22, wherein the air outlet 22 of the rain shield pipe 2 is connected with the air inlet 11 of the electric air valve 1 in a sealing manner. The air inlet 21 on the rain-proof cover pipe 2 is arranged at the lower side of the rain-proof cover pipe 2 close to one side end part, the isolation net 23 is arranged at the position of the air inlet 21, the possibility that rainwater can directly enter is reduced when the air inlet 21 is arranged downwards, and the isolation net 23 can prevent insects, birds or other sundries from entering the rain-proof cover pipe 2 from the air inlet 21.

A first water baffle 24 and a second water baffle 25 which extend upwards from the bottom are arranged in the rain shield pipe 2, the first water baffle 24 and the second water baffle 25 are arranged at intervals, the first water baffle 24 is closer to the air inlet relative to the second water baffle 25, and in the embodiment, the second water baffle 25 is arranged at the end part of the air outlet 22; a first water outlet 26 is arranged between the first water baffle 24 and the air inlet 21, and a second water outlet 27 is arranged between the second water baffle 25 and the first water baffle 24. The height of the second water baffle 25 is higher than that of the first water baffle 24; the height of the second water baffle 25 is 1/3-1/2 of the diameter of the rain-proof cover pipe 2. A drain pipe 3 with a front end inlet communicated with the second water outlet 27 is arranged outside the rain shield pipe 2, and a rear end outlet of the drain pipe 3 is arranged at the lower side of the first water outlet 26; a baffle 4 is arranged at the outlet at the rear end of the drain pipe 3, and the baffle 4 is rotatably connected to the lower side of the rain cover pipe 2.

When the electric air valve 1 is opened, the air inlet 11 and the air outlet 12 of the electric air valve 1 are communicated, and outside air enters the rain-proof cover pipe 2 from the air inlet 21 of the rain-proof cover pipe 2 and enters a room through the electric air valve 1. The first water baffle 24 in the rain shield pipe 2 is used for isolating most of the sucked rainwater, the isolated rainwater can flow out along the first drainage port 26, and the rainwater can be sucked and gathered near the first drainage port 26 due to pressure and wind speed when the rainwater is low. The water flow may exit the first drain opening 26 when rainwater collects in the water flow and gravity overcomes the suction force. The second water baffle 25 is higher than the first water baffle 24, the water accumulation area between the second water baffle 25 and the first water baffle 24 is less influenced by air flow suction, and when rainwater climbs over the first water baffle 24 under the influence of negative pressure and wind speed, the rainwater can stagnate in the water accumulation area between the first water baffle 24 and the second water baffle 25 and flow out of the drain pipe 3 through the second water outlet 27. Because the ponding region is influenced by air current suction for a short time, the ponding region has second outlet 27, and the rainwater can not climb over second water baffle 25, and this structure water-proof effects is good.

When the rain cover is installed, after a hole passing through the rain cover pipe 2 is formed in the wall body 5, the rain cover extends out of the room from the indoor to the outdoor, the electric air valve is located indoors, the air inlet 21 and the first water outlet 26 of the rain cover pipe are located outdoors, other parts of the rain cover pipe 2 are located in the hole of the wall and indoors, and the air supplement valve structure is shown in fig. 4.
