Self-adaptive wind direction and natural draft smoke exhaust device that can adjust resistance in linkage

Abstract

A natural induced air smoke exhaust device capable of being adaptive to the wind direction and adjusting resistance in a linkage mode is characterized in that the natural induced air smoke exhaust device comprises an air inlet pipe rotating along with the wind direction, a horn-shaped air inlet is formed in the lower end of the air inlet pipe, the upper end of the air inlet pipe is connected with the lower end of a vertical pipeline through a bearing in a sleeved mode, and the air inlet pipe pivots relative to the vertical pipeline; the air inlet pipe wall on the opposite side of the air inlet is provided with a vertical wind wing; a fixing support is arranged in the middle of the vertical pipeline, a supporting rod is arranged on the fixing support, an oscillating bar is hinged to the end of the supporting rod, a reset spring is arranged at the hinged position, a flue gate is fixed to the upper end of the oscillating bar, and the flue gate can reset to the half-aperture original position through the reset spring; the lower end of the oscillating bar extends to make single-face contact with the vertical wind wing; a flue and the vertical pipeline are converged at the upper portion of the vertical pipeline in the 45-degree included angle.

Description

technical field [0001] The invention belongs to the technical field of natural smoke exhaust from heating stoves, and in particular relates to a natural induced draft smoke exhaust which can form negative pressure through the action of natural wind to promote smoke exhaust, prevent backflow and poor smoke exhaust, and can adjust the internal resistance of the chimney according to the wind direction. device. Background technique [0002] Residents in some areas in northern my country where central heating has not been implemented still use household stoves for heating, and the smoke is generally discharged naturally, that is, the outlet end of the chimney is directly placed in the outdoor air. poisoned. Some chimneys, such as utility model patents CN203099863U, 95229876.7, 200920108105.3, 200920017431.3, 201320266509.1, 201320052976.4, 91203516.1, etc., all mention the use of wind vanes to adjust the position of the windward outlet, which solves the problem of windward pourin...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the problem of the chimney flowing backwards against the wind and the inability of the existing induced draft chimney to effectively utilize the outdoor wind, the present invention provides a natural induced draft smoke exhaust device that is self-adapting to the wind direction and can adjust resistance in linkage
