Description
Technical field
The present invention relates to a kind of variable cross-section type exhaust gas flue, more particularly to a kind of anti-smoke blowing smoke discharging of variable cross-section type
Road, belong to flue manufacturing.
Background technology
At present, exhaust gas flue is widely used on house, resident in daily life, kitchen, the row of toilet
Feed channel is connected with public exhaust duct realizes the discharge of cigarette, gas, in real life, upstairs house usually occurs and cooks
There is smoke blowing in room or toilet, phenomenon of collaborating, and certain influence is generated on the health of resident.According to air circulation
Principle is learned, minimum by circle resistance during same air quantity, circular inwall is more beneficial for air circulation, but round
For shape exhaust gas flue there is also the defects of heavier, production cost is high of conducting oneself with dignity, best bet is can either to increase flue gas
The velocity of discharge, and can reduce exhaust gas flue weight and cost.
The content of the invention
Part in order to overcome the above-mentioned deficiencies of the prior art, the present invention provide a kind of anti-smoke blowing smoke discharging of variable cross-section type
Road, can reduce the weight of exhaust gas flue, and and can accelerates cigarette, the velocity of discharge of gas, and avoid the occurrence of smoke blowing,
Collaborate phenomenon.
The present invention is achieved through the following technical solutions：Described exhaust gas flue is by cuboid cavity and cylinder
Through hole cavity is formed, and described cuboid cavity is surrounded and formed by side wall one, side wall two, side wall three, side wall four,
Described cylindrical hole cavity inner wall keeps tangent with side wall one, side wall two, the inwall of side wall three respectively；It is described
Cuboid cavity inner wall and cylindrical hole cavity inner wall realize square-section to circle by intermediate incline
The transition in section, described intermediate incline connect cuboid cavity cut-off for two by cylindrical hole cavity
Logical region, form the flue collector mouth that a square-section becomes circular cross-section.
Described side wall four, intermediate incline and cylindrical hole cavity side is encircled into bottom lock, top end opening
Water conservancy diversion channel-shaped region, formed auxillary flue；Described side wall four is provided with air inlet, and described air inlet is located at
Intermediate incline top side simultaneously connects with auxillary flue realization, and described auxillary flue is in closing with flue collector mouth bottom
State, the flue gas at auxillary flue is discharged upwards and converge with flue collector mouth flue gas on top, on flue collector mouth top
Hold and discharged upwards under the drive of flue gas stream, so as to avoid the occurrence of smoke blowing, phenomenon of collaborating.
Described intermediate incline could alternatively be curved surface.
It is an advantage of the invention that：Compared with traditional exhaust gas flue, the present invention is by being sky by square-section transition
The more preferable circular cross-section of gas trafficability performance, sectional area, which diminishes, promotes the flow velocity of flue gas in cylindrical hole cavity to accelerate
And discharge upwards.After the flue gas in residential building enters auxillary flue via air inlet, arranged upwards along auxillary flue
Go out, now flue collector mouth flue gas Accelerating Removal and drives auxillary flue flue gas to discharge upwards forward, makes auxillary flue cigarette
Gas can not scurry into other floors, so as to avoid the occurrence of smoke blowing, phenomenon of collaborating, compared to round exhaust gas flue in general,
Both weight is alleviated, adds flow velocity again, improves the practicality of exhaust gas flue.

Embodiment
With reference to example and accompanying drawing, the invention will be further described：
As shown in the figure：A kind of anti-smoke blowing exhaust gas flue of variable cross-section type, described exhaust gas flue is by cuboid cavity 1
Formed with cylindrical hole cavity 2, described cuboid cavity 1 is by side wall 1, side wall 26, side wall three
7th, side wall 48 surrounds composition, the described inwall of cylindrical hole cavity 2 respectively with side wall 1, side wall 26,
The inwall of side wall 37 keeps tangent, and the described inwall of cuboid cavity 1 passes through with the inwall of cylindrical hole cavity 2
Intermediate incline 3 realizes transition of the square-section to circular cross-section, and described intermediate incline 3 is by cuboid cavity 1
Separate and become circular cross-section for two regions connected by cylindrical hole cavity 2, one square-section of formation
Flue collector mouth 10, attended a school by taking daily trips principle according to air stream, circular inwall is more beneficial for the circulation of flue gas, so working as
Trafficability performance is more preferable when flue gas is by described cylindrical hole cavity 2, due to the section of flue collector mouth 10 by
Square-section transition is circular cross-section, the sectional area of flue collector mouth 10 is diminished to a certain extent, in equal gas
On the premise of flowing flow, the flow velocity of flue gas at cylindrical hole cavity 2 is accelerated.
Described side wall 48, intermediate incline 3 and the side of cylindrical hole cavity 2 is encircled into bottom lock, top
The water conservancy diversion channel-shaped region of end opening, form auxillary flue 9；Described side wall 48 is provided with air inlet 4, described
Air inlet 4 be located at the top side of intermediate incline 3 and with auxillary flue 9 realize connect, for connect resident discharge
Flue gas, the auxillary flue 9 and the bottom of flue collector mouth 10 are in closed state, avoided at auxillary flue 9
Altered under flue gas, when flue gas is discharged into auxillary flue 9 by air inlet 4, flue gas is discharged upwards via auxillary flue 9,
And converge with the flue gas of flue collector mouth 10 on top, because flow velocity accelerates at cylindrical hole cavity 2, in master
The top of floss hole 10 formed negative pressure, so as to drive the flue gas of auxillary flue 9 quickly to discharge upwards, avoid the occurrence of smoke blowing,
Collaborate phenomenon.
Described intermediate incline 3 could alternatively be curved surface, for realizing transition of the square-section to circular cross-section.
