Wind pressure resistant smoke pipe

Abstract

A wind pressure resistant smoke pipe comprises a smoke pipe body (1). The wind pressure resistant smoke pipe is characterized in that a rotating shaft (2) is axially and rotatably arranged in the smoke pipe body (1), a fan (22) is arranged at the front end of the rotating shaft (2), a first conical gear (21) is arranged at the rear end of the rotating shaft (2), correspondingly, smoke exhaust holes (11) are formed in the side wall of the smoke pipe body (1), exhaust fans (5) capable of exhausting smoke in the smoke pipe body (1) to the outside are rotatably arranged on the smoke exhaust holes(11) close to the front, each exhaust fan (5) rotates coaxially with a second conical gear (6), and the second conical gears (6) are in meshing transmission with the first conical gear (21). Comparedwith the prior art, the wind pressure resistant smoke pipe has the advantages that external wind drives the fans to rotate, so that a wind wheel is synchronously driven to rotate, the wind wheel supplies air to smoke and discharges the smoke from the smoke exhaust holes, the larger the external wind is, the larger the wind supply power of the wind wheel is, and the purpose of resisting wind pressure is achieved.

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...
