A high-rise building water heater waste gas exhaust device

Abstract

The invention discloses a waste gas exhaust device for a high-rise building water heater, which comprises a water heater body and a smoke exhaust pipe. The water heater body is respectively provided with an air inlet and an air outlet, and the air inlet and the air outlet are respectively sealed and connected with an air inlet pipe. and the outlet pipe, the exhaust pipe is sealed and slidably connected with a push plate, the end of the outlet pipe away from the water heater body is sealed and connected with the push plate, the push plate is rotatably connected with an impeller, and the connection between the smoke exhaust pipe and the push plate A chute is opened at the place, and the chute is connected with an annular piezoelectric ring, and the two sides of the push plate are respectively provided with a fixed plate and a rotating plate. The advantage is that in the state of high external wind pressure, the push plate is pushed by the air pressure to make it contact with the piezoelectric ring and conduct the circuit, so that the piezoelectric ring charges the flat plate capacitor composed of the push plate and the fixed plate under the action of pressure And finally breakdown, under the action of instantaneous breakdown heat, push the push plate back, so as to discharge the waste and avoid causing safety problems.

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...
