Embodiment 1

[0026] Such as figure 1 As shown, the present embodiment provides a hyperboloid chimney cap, comprising a first curved cover 3 and a second curved cover 2, the first curved cover 3 is fixedly connected to the second curved cover 2 via a first telescopic column 42, and the second curved cover 2 The clamping ring 43 is assembled and connected through the second telescopic column 41, and the clamping ring 43 is assembled and connected to the end position of the chimney 1. At the end position of the chimney 1 , the opening directions of the first curved surface cover 3 and the second curved surface cover 2 are opposite, and a top cover 31 is provided on the first curved surface cover 3 . A mask hole 21 is opened at the central position of the second curved mask 2 , and the area of ​​the section of the mask hole 21 is smaller than the area of ​​the opening section of the chimney 1 . The flue gas discharged from the chimney 1 first enters the second curved mask 2, at this time, the...

Embodiment 2

[0028] The difference between this embodiment and the first embodiment is that a drain hole 32 is provided in the center of the first curved surface cover 3 , and the drain hole 32 is connected to a drain pipe 33 . Like this, the rainwater on the first curved surface cover 3 can flow out through drainpipe 33, avoids the first curved surface cover 3 top water accumulation.

Abstract

The invention proposes a double-curved-surface chimney cap. The double-curved-surface chimney cap comprises a first curved surface cover and a second curved surface cover; the first curved surface cover is fixedly connected with the second curved surface cover by a first connecting column; the second curved surface cover is assembled and connected with a chimney tail end position by a second connecting column; opening directions of the first curved surface cover and the second curved surface cover are opposite; a surface cover hole is formed in the center position of the second curved surface cover; and the section area of the surface cover hole is smaller than the section area of a chimney opening. The double-curved-surface chimney cap has the following beneficial effects: a negative-pressure area is formed in a space between the first curved surface cover and the second curved surface cover, so that smoke in a chimney is discharged more smoothly; air currents quickly enter the space between the first curved surface cover and the second curved surface cover to take away the smoke; the size of the space between the first curved surface cover and the second curved surface cover is adjustable to change the negative-pressure degree of the negative-pressure area so as to adjust the discharge of the smoke in the chimney; and the distance from the second curved surface cover to the chimney is adjustable to adjust the proper quantity of the smoke in the chimney entering the second curved surface cover.

Description

technical field [0001] The invention relates to the technical field of combustion appliances, in particular to a hyperboloid chimney cap. Background technique [0002] Chimneys are very common in daily life, and the chimney caps used for chimneys are also relatively common. The chimney caps are arranged on the top of the chimney and are pointed in shape to keep out rain and snow. In order to increase the speed of exhausting the smoke, a smoke exhauster is generally installed in the chimney cap. However, on the one hand, the smoke exhaust machine increases energy consumption, and on the other hand, the smoke exhaust machine also needs regular inspection and maintenance. The design of setting the smoke exhauster in the chimney cap increases the economic investment, the use process is cumbersome, and the overall service life is short. Contents of the invention [0003] The object of the present invention is to provide a hyperboloid chimney cap to improve the smoke exhaust r...
