Anti-wind pressure smoke pipe

Abstract

The invention discloses an anti-wind pressure smoke pipe. The smoke pipe is characterized by comprising a wind inlet grille, a first smoke pipe body, a second smoke pipe body, a driving impeller, a first anti-wind impeller and a second anti-wind impeller, wherein the first smoke pipe body is arranged at one side of the wind inlet grille, a smoke exhaust hole is formed in the side wall of the firstsmoke pipe body, the second smoke pipe body is arranged at the other side of the wind inlet grille, and an installation space is formed between the second smoke pipe body and the first smoke pipe body; and the driving impeller is rotatably arranged on the installation space and comprises a hollow rotating drum and driving blades arranged on the periphery of the rotating drum, and the natural windcoming in from the wind inlet grille can drive the driving impeller to rotate. The external wind enters through the wind inlet grille, the wind force drives the driving impeller to rotate to drive afirst rotating shaft and a second rotating shaft to rotate, and the first anti-wind impeller and the second anti-wind impeller are driven to rotate, so that the air in the smoke pipe is discharged, and the purpose of resisting the wind pressure by using the natural wind is realized. The structure is compact, the design is exquisite, and no additional energy consumption device is needed.

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...
