Description
Technical Field
The invention belongs to the technical field of chimneys, and particularly relates to a chimney cap with a self-adjusting function.
Background
The chimney is common in daily life, and a chimney cap used by the chimney is also common, is arranged at the top end of the chimney and is in a pointed shape for shielding rain and snow.
High-temperature smoke is in a straight-line rising state when being discharged, but because the chimney cap is arranged, the rising path of the high-temperature smoke can be blocked, the smoke can only diffuse to the periphery after being blocked, and a certain distance is required between the chimney cap and the top end of the chimney; if the distance is too small, the space for diffusing the smoke to the periphery is small, so that the diffusion rate of the smoke is reduced; if the distance is too large, the possibility that foreign matters in the air float into the chimney is improved.
