Waste gas exhaust device of water heater of high-rise building

Abstract

The invention discloses a waste gas exhaust device of a water heater of a high-rise building. The waste gas exhaust device involves a water heater body and a smoke exhaust pipe, wherein an air inlet and an air outlet are formed in the water heater body, the air inlet and the air outlet are connected with an air inlet pipe and an air outlet pipe respectively in a sealed mode, the smoke exhaust pipeis connected with a push plate in a sealed and sliding mode, the end, away from the water heater body, of the air outlet pipe is connected with the push plate in a sealed mode, the push plate is rotationally connected with an impeller, a sliding groove is formed in the joint between the smoke exhaust pipe and the push plate, the sliding groove is connected with an annular piezoelectric ring, anda fixed plate and a rotating plate are arranged on the two sides of the push plate correspondingly. The device has the advantages that the push plate is pushed through air pressure to make contact with the piezoelectric ring and conduct a circuit under the state that the external air pressure is large, the piezoelectric ring charges a plate capacitor composed of the push plate and the fixed plateunder the action of the pressure and finally breaks the plate capacitor down, the push plate is reversely pushed under the action of instant breakdown heat, so that waste gas is discharged, and safetyissues are avoided.

Description

technical field [0001] The invention relates to the technical field of high-rise building equipment, in particular to a high-rise building water heater waste gas exhaust device. Background technique [0002] A water heater refers to a device that raises the temperature of cold water into hot water within a certain period of time through various physical principles. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, and air energy water heaters. water heater etc. [0003] The water heater realizes heating by burning combustible gas when boiling water, so that waste gas will be generated during work, which includes waste gases such as carbon monoxide and sulfur dioxide that are not completely burned, and are generally discharged through exhaust pipes and ventilation fans. However, in the prior art When using water heaters in high-rise buildings, due to the strong wind force a...
