Abstract

The utility model relates to a technical field is prevent wind to the flue, is a cap is prevent wind to flue, it includes the opening last segment body, the opening lower segment body and sleeve pipe down up, goes up the segment body and be in the same place through bracing piece fixed connection two at least with the segment body down, goes up the segment body and has a cigarette interval between the segment is personally experienced sth. Part of the body down, and there is the outlet flue at the top that the segment was personally experienced sth. Part of the body under, fixes on the internal wall of lower segment outside the outlet flue on the sheathed tube. The utility model discloses simple structure during the use, will overlap the pipe box and establish on the chimney, because it is relative with the sphere of the segment body down to be the sphere of going up the segment body, the wind comes from of any orientation all is difficult for entering into the chimney, the wind comes from to pass by still can produce the wind pressure and make the velocity of flow accelerate, and lee side makes wind spread rapidly again, produces pulling function, and the chimney exhaust is hot cigarette simultaneously, clearance follow -up between sleeve pipe and the chimney be cold wind to make the flue gas rise and accelerate, thereby it is smooth and easy to discharge fume.

Description

Flue wind-proof cap

Technical field

The utility model relates to the windproof technical field of flue, is a kind of flue wind-proof cap.

Background technology

General boiler heating or the chamber of a kitchen range are lit a fire and are all provided with smokejack, but chimney violates wind, down draught, the cigarette that falls is common occurrence, also be a troubling thing, in order to address this problem, what have increases chimney, and what have then puts an air-introduced machine, although play a role, but use expense electricity charge work, cleaning chimney dust stratification is also pretty troublesome.

Summary of the invention

The utility model provides a kind of flue wind-proof cap, overcome the deficiency of above-mentioned prior art, it in use, casing pipe sleeve is located on chimney, because the sphere being upper spheroid is relative with the sphere of lower spheroid, the wind comes from of any direction all not easily enters into chimney, the wind comes to pass by and also can produce blast and flow velocity be accelerated, lee face makes again wind spread rapidly, produce pulling function, what chimney was discharged simultaneously is hot cigarette, and what followed up in the gap between sleeve pipe and chimney is cold wind, thus flue gas rising is accelerated, thus it is smooth and easy to discharge fume.

The technical solution of the utility model is achieved like this: a kind of flue wind-proof cap, comprise opening up upper spheroid, downward opening lower spheroid and sleeve pipe, upper spheroid and lower spheroid are fixed together by the support bar of at least two, smoke spacing is had between upper spheroid and lower spheroid, have outlet flue at the top of lower spheroid, the upper end of sleeve pipe is fixed on the lower spheroid inwall outside outlet flue.

As preferably, above its lower end inwall is circumferentially interval with the chuck of energy seat on chimney.

As preferably, the top of above upper spheroid is fixed with the ventricumbent rain cover of arc, and the outer face of rain cover is positioned at the outside of spheroid.

As preferably, above upper spheroid and lower spheroid are semicircle spheroid.

As preferably, be four with upper support bar and circumferentially uniform intervals distribution.

The utility model structure is simple, during use, casing pipe sleeve is located on chimney, because the sphere being upper spheroid is relative with the sphere of lower spheroid, the wind comes from of any direction all not easily enters into chimney, the wind comes to pass by and also can produce blast and flow velocity be accelerated, lee face makes again wind spread rapidly, produces pulling function, what chimney was discharged simultaneously is hot cigarette, what followed up in the gap between sleeve pipe and chimney is cold wind, thus flue gas rising is accelerated, thus it is smooth and easy to discharge fume.

Accompanying drawing explanation

Fig. 1 is main TV structure figure of the present utility model;

Fig. 2 is the top view of lower spheroid in the utility model.

Coding in figure is respectively: 1 is upper spheroid, and 2 is lower spheroid, and 3 is sleeve pipe, and 4 is support bar, and 5 is outlet flue, and 6 is rain cover, and 7 is chimney.

Detailed description of the invention

As shown in Figure 1 and Figure 2, this flue wind-proof cap, comprise opening up upper spheroid 1, downward opening lower spheroid 2 and sleeve pipe 3, the support bar 4 that upper spheroid 1 and lower spheroid 2 pass through at least two is fixed together, smoke spacing is had between upper spheroid 1 and lower spheroid 2, have outlet flue 5 at the top of lower spheroid 2, the upper end of sleeve pipe 3 is fixed on the lower spheroid inwall outside outlet flue 5.During use, sleeve pipe 3 is set on chimney 7, because the sphere being upper spheroid 1 is relative with the sphere of lower spheroid 2, the wind comes from of any direction all not easily enters into chimney 7, the wind comes to pass by also can produce blast and flow velocity be accelerated, lee face makes again wind spread rapidly, produce pulling function, what chimney 7 was discharged simultaneously is hot cigarette, and what followed up in the gap between sleeve pipe 3 and chimney 7 is cold wind, thus flue gas rising is accelerated, thus it is smooth and easy to discharge fume.

For the ease of being sleeved on chimney 7, sleeve pipe 3 lower end inner wall is circumferentially interval with can the chuck of seat on chimney 7.

As shown in Figure 1, the top of upper spheroid 1 is fixed with the ventricumbent rain cover 6 of arc, and the outer face of rain cover 6 is positioned at the outside of spheroid 1.When can prevent rainy like this, rainwater enters into chimney.

As shown in Figure 1, as required, upper spheroid 1 and lower spheroid 2 are semicircle spheroid.

As shown in Figure 1, support bar 4 is four and circumferentially uniform intervals distribution.Such installation is more stable.
