One end of the smoke exhaust pipe interface 1 is installed on the air collector hood body, and the wind deflector 5 is located inside the smoke exhaust pipe interface 1. It is characterized in that: it also has a plurality of second fixing components 32, a plurality of third fixing components 33, and a second ventilation component 4; the second ventilation component 4 is composed of a second body 41, the upper surface of the second body 41 has a recessed second groove 42, the second body 41 has a second ventilation hole 43 that penetrates up and down, and the inner wall of the second groove 42 has a recessed connection hole 44; the wind deflector 5 is composed of a valve body 51 and a connecting body 52, and the connecting body 52 extends out from the side of the valve body 51; in the assembled state, the second fixing components 32 are distributed on the inner wall of the smoke exhaust pipe interface 1, and all the second fixing components 32 are at the same vertical height on the inner wall of the smoke exhaust pipe interface 1; the third fixing components 33 are distributed on the inner wall of the smoke exhaust pipe interface 1, and all the third fixing components 33 are at the same vertical height on the inner wall of the smoke exhaust pipe interface 1; on the inner wall of the smoke exhaust pipe interface 1, the third fixing components 33 are located below the second fixing components 32; the connecting body 52 is inserted into the connection hole 44, the valve body 51 is located in the second groove 42 and floatingly covers the second ventilation hole 43, and the valve body 51 can rotate up and down around the connecting body 52.

[0023] The above-mentioned gas water heater air collector hood that is easy to install is characterized in that: it also has a plurality of first fixing parts 31 and a first ventilation component 2; the first ventilation component 2 is composed of a first body 21, and the first body 21 has a plurality of first ventilation holes 22 that penetrate up and down; in the assembled state, the first fixing parts 31 are distributed on the inner wall of the smoke exhaust pipe interface 1, and all the first fixing parts 31 are at the same vertical height on the inner wall of the smoke exhaust pipe interface 1. On the inner wall of the smoke exhaust pipe interface 1, the second fixing component 32 is located below the first fixing part 31.

[0024] Further, the above-mentioned gas water heater air collector hood that is easy to install is characterized in that: the center of the first body 21 is penetrated up and down, and a first telescopic body 211 is fixed inside the first body 21, and the first ventilation holes 22 are located on the first telescopic body 211.

[0025] The above-mentioned gas water heater air collector hood that is easy to install is characterized in that: the first telescopic body 211 is a mesh or mesh cloth or gauze structure, and can move upward and ventilate when blown by the wind.

[0026] For the above-mentioned gas water heater air collector hood that is easy to install, the term "a plurality" means not less than two, and can be Figure 7 four in Figure 8 three in

[0027] In this application, Figure 7 , Figure 8 the 31 pieces of the first fixing part, the second fixing part 32, the third fixing part 33 and the smoke exhaust pipe interface 1 in Figures 2 to 5 are of an integrated structure, which is pre-welded on the smoke exhaust pipe interface 1 and then formed into an integrated structure by winding and welding the smoke exhaust pipe interface 1; of course, it can also be as shown in

[0028] In this application, the second ventilation part 4 is stuck between the second fixing part 32 and the third fixing part 33, and it can only rotate circumferentially. However, when exhausting, when the gas reaches a certain pressure, the valve body 51 rotates upward, so that the gas rushes out of the smoke exhaust pipe interface 1 from the second ventilation hole 43, achieving the purpose of exhausting. When the gas pressure is insufficient, due to the gravity of the valve body 51, it automatically rotates downward and rests on the protruding part of the second body 41 in the second groove 42, making it completely isolated from the outside.

[0029] On the other hand, when there is the first ventilation part 2, the upward-rushing gas rushes out through the first ventilation hole 22.

[0030] Since in actual use, the pipeline connected to the smoke exhaust pipe interface 1 may not be installed to the extent that gas and water do not flow back. Therefore, in windy and rainy weather, external gas and water may partially flow back into the smoke exhaust pipe interface 1, and the valve body 51 effectively blocks it; of course, when there is the first ventilation part 2, since the mesh structure can condense moisture, it can also effectively prevent the inflow of moisture.

[0031] When installing this application, only need to insert the first ventilation part 2 and / or the second ventilation part 4 from above or below the smoke exhaust pipe interface 1, as long as the 31 pieces of the first fixing part, the second fixing part 32, and the third fixing part 33 can block it, and it is quite convenient and fast to take out.
