Problems solved by technology

[0003] 1. When the wind pressure is too high, the flue gas cannot be discharged normally, which will affect the combustion of gas and reduce the efficiency
[0004] 2. The wind blows back into the water heater, which will lead to backfire, flameout, CO exceeding the standard and other dangerous situations

Abstract

A smoke exhaust pipe, comprising a smoke pipe body, characterized in that the smoke pipe body is provided with a front stop ring and a rear stop ring, and a reversing section is formed between the front stop ring and the rear stop ring of the smoke pipe body, the The reversing section is provided with a first air outlet hole and a second air outlet hole, and the inner ring of the reversing disc is provided with a first air inlet hole matched with the aforementioned first air outlet hole and a second air outlet hole matched with the aforementioned second air outlet hole. Two air intake holes. Correspondingly, the front end surface and the rear end surface of the aforementioned reversing disc are respectively provided with a front air outlet opening communicating with the first air intake hole and a rear air outlet opening communicating with the second air intake hole. According to the external wind direction, the reversing disc can make corresponding movements to change the direction of the wind, change the direction of the smoke flow, and have a good anti-backwind effect.

Description

technical field [0001] The invention relates to a smoke exhaust pipe, in particular to a smoke exhaust pipe applied to gas water heaters, range hoods or dual-purpose furnaces 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 do...
