A kind of anti-wind pressure smoke pipe

Abstract

A wind pressure resistant smoke pipe, comprising a smoke pipe body (1), characterized in that a rotating shaft (2) is rotatably arranged in the axial direction of the smoke pipe body (1), and the front end of the rotating shaft (2) is provided with The fan (22), the rear end is provided with a first bevel gear (21), correspondingly, a smoke exhaust hole (11) is opened on the side wall of the smoke pipe body (1), close to the aforementioned smoke exhaust hole (11) An exhaust fan (5) that can discharge the flue gas in the smoke pipe body (1) to the outside can be rotatably provided. The exhaust fan (5) rotates coaxially with a second bevel gear (6). The second bevel gear (6) is engaged with the aforementioned first bevel gear (21) for transmission. Compared with the prior art, the present invention has the advantages that: the outside wind drives the fan to rotate, and then synchronously drives the wind wheel to rotate, and the wind wheel sends air to the flue gas, which is discharged from the smoke exhaust hole. The greater the power, so as to achieve the purpose of wind pressure resistance.

Description

technical field [0001] The invention relates to a smoke exhaust pipe, in particular to a smoke exhaust pipe applied to a gas water heater or a range hood. Background technique [0002] In the process of daily use of products such as water heaters or range hoods, once encountering strong winds, the exhaust of smoke will be greatly affected, and the water heater may even be turned off due to this, which will seriously affect the use and safety of users. Specifically, the following problems will occur : [0003] 1. When the wind pressure is too high, the flue gas cannot be discharged normally, which affects the combustion of gas and reduces the efficiency. [0004] 2. If the wind blows backwards into the water heater, it will lead to dangerous situations such as flashback, flameout, and CO exceeding the standard. [0005] In terms of anti-backwind, many efforts and attempts have been made in the prior art, as shown in the Chinese utility model patent "a double anti-backwind s...
