Background

The smoke exhaust pipe assembly is generally connected with a boiler such as a wall-mounted boiler through an elbow for smoke exhaust and air intake of boiler equipment; the tub subassembly of discharging fume can be divided into condensing and non-condensing according to its applied environment's difference, and wherein condensing is discharged fume the pipe subassembly and is generally the slope and upwards arranges when concrete installation, so when raining, the rainwater can flow in the boiler along the pipe wall of intake pipe to can influence the use of boiler, not only can reduce the work efficiency of boiler, can lead to the boiler to rust the damage simultaneously, consequently have improved space.

SUMMERY OF THE UTILITY MODEL

The utility model relates to an overcome defect among the above-mentioned prior art, provide a condensing smoke exhaust pipe assembly that can prevent rainwater from flowing backward, through the groove of converging of the sunken formation on the interior pipe wall of intake pipe, can effectively block that the rainwater is direct in flowing into the boiler along the pipe wall, the groove of converging simultaneously can play the effect of converging the rainwater for it can quick effectual wash port realization outer row to converge the rainwater in the inslot, thereby guarantees the normal use of boiler, guarantees the life of boiler.

In order to achieve the purpose, the utility model provides a condensation type smoke exhaust pipe assembly capable of preventing rainwater from flowing backwards, which comprises an air inlet pipe, a smoke exhaust pipe positioned in the air inlet pipe, and a smoke cap sleeved with the outlet end of the smoke exhaust pipe and the inlet end of the air inlet pipe to realize the separation of a smoke exhaust path and an air inlet path, wherein the smoke cap comprises a smoke exhaust part matched with the smoke exhaust pipe and an air inlet part matched with the air inlet pipe, the smoke exhaust part or the air inlet pipe of the smoke cap is provided with an air inlet hole, and the smoke exhaust part of the smoke cap is provided with a smoke exhaust hole;

and a converging groove which is formed by the inward and outward concave inner wall and is used for converging rainwater is formed on the pipe wall of the air inlet pipe below the air inlet hole, and a drain hole is formed in the converging groove.

Further setting the following steps: the confluence groove is arranged along the circumference of the pipe wall of the air inlet pipe.

Further setting the following steps: the cigarette cap is of a sleeve type structure and comprises an outer barrel located outside, an inner barrel located in the outer barrel and a connecting rib connected between the inner barrel and the outer barrel, wherein the outer barrel is an air inlet part, and the inner barrel is a smoke exhaust part.

Compared with the prior art, the utility model has the advantages of simple and reasonable structure, through the groove of converging of sunken formation on the inner tube wall of the pipe of discharging fume, can effectively block that the rainwater is direct in flowing into the boiler along the pipe wall, the groove of converging simultaneously can play the effect of converging the rainwater for it can quick effectual wash port realization outer row to converge the rainwater in the groove, thereby guarantees the normal use of boiler, guarantees the life of boiler.
