Description

But the chimney that box haul changes

Technical field

The utility model relates to a kind of chimney, specifically, but is the chimney that box haul changes.

Background technology

The throat majority of existing chimney and the axis normal of chimney stack.Like this, when blowing,,, form cigarette so wind can blow back cigarette in the chimney stack because the axis of wind and chimney stack has some angles; When raining, rainwater directly falls in the chimney stack, can influence fume emission.

Goal of the invention

The purpose of this utility model is a kind of novel chimney of design, makes this chimney blow, can both normally discharge fume when raining.

Technical scheme

The utility model is to realize purpose of design like this.Upper port at chimney stack is equipped with spin; Chimney cowl is housed on spin; Fan blade with the axis normal of chimney stack is housed on the outer periphery of chimney cowl; The upper port of chimney cowl is an axis throat at an angle with chimney stack; Rain cover is housed on the throat.

When blowing, fan blade can drive chimney cowl and rotate, make throat high-end aligning wind blow direction, the low side of throat is aimed at the direction of blowing away of wind.Wind just can not blow in the chimney stack like this; Owing on the throat rain cover is housed, so rainwater can directly not fall in the chimney stack.

The utility model is made easily, and result of use is good.

Description of drawings

Fig. 1 is the utility model schematic diagram.

The specific embodiment

Below in conjunction with Fig. 1, a non-limiting examples is illustrated.Upper port dress spin 2 at chimney stack 1; Dress chimney cowl 4 on the spin 2; Fan blade 3 with the axis normal of chimney stack 1 is housed on the outer periphery of chimney cowl 4; Fan blade 3 is made the arrow shape of tail, be installed in the below of the low side of throat 5; The upper port of chimney cowl 4 is made angle with the axis 40-50 degree angle of chimney stack 1, form throat 5; Rain cover 6 is housed on the throat 5, and rain cover 6 can be made umbrella with iron sheet, makes the external diameter of the lower diameter of cover greater than chimney cowl, with 3 above round steel cover is fixed on the throat 5 again.

Use chimney of the present utility model, it is unobstructed to discharge fume, not the interference of wind-engaging, rain.
