Description
Technical field
The utility model relates to a kind of fluid-tight backstop that is used for the smoke discharging passage.
Background technology
The kitchen fume and the peculiar smell in toilet of existing dwelling house often seal within doors by the smoke vent or the exhaust duct in kitchen.
The utility model content
Goal of the invention of the present utility model is to provide a kind of fluid-tight backstop that is used for the smoke discharging passage, can effectively avoid exhaust gases passes to seal in peculiar smell.
Realize the present utility model purpose technical scheme:
A kind of fluid-tight backstop that is used for the smoke discharging passage, comprise into fume pipe, smoke evacuation tracheae, it is characterized in that: also comprise seal groove, fill sealing fluid in the seal groove, advance fume pipe and pass seal groove, the upper outside of advancing fume pipe is provided with the middle cover that can be promoted by blast, and the lower end of middle cover is positioned at seal groove; The end face of cover can be along its slideway that slides up and down in also being provided with, and the bottom of slideway is positioned at into fume pipe, and the top of slideway is arranged in the top of cover end face; Seal groove, middle cover, slideway all are positioned at housing, and housing is connected to out fume pipe.
Be provided with a slideway, slideway is along the axial line setting of advancing fume pipe.
The beneficial effect that the utlity model has:
The principle of the utility model applied aerodynamics and liquid seal, utilize the blast of smoke exhaust ventilator or ventilation fan promote in cover, cover moves up along slideway in making, the sealing liquid level is left in the cover lower end in making, flue gas is discharged; When smoke exhaust ventilator or ventilation fan were not worked, middle cover fell because of action of gravity, and middle cover lower end is positioned at sealing fluid, utilizes liquid seal, effectively avoids exhaust gases passes to seal in peculiar smell.Slideway only is provided with one, and the axial line setting along advancing fume pipe more helps simplified structure, and moving up and down of covering in making is more smooth and easy.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, fill sealing fluid 5 in the seal groove 4, advance fume pipe 2 and pass seal groove, the upper outside of advancing fume pipe is provided with the middle cover 1 that can be promoted by blast, and the lower end of middle cover is positioned at seal groove; The end face of cover can be along its slideway that slides up and down 6 in also being provided with, and slideway is provided with one, along the axial line setting of advancing fume pipe.The bottom of slideway 6 is positioned at into fume pipe 2, and the top of slideway is arranged in the top of cover 1 end face; Seal groove, middle cover, slideway all are positioned at housing 9, and housing is connected to out fume pipe 3.Also be provided with filling opening 8 on the housing, be used to add sealing fluid, also be provided with and be used for the sealing liquid level liquid level meter 7 of monitoring.
When smoke exhaust ventilator or ventilation fan work, cover 1 end face upwards slided along slideway 6 during blast made, the sealing liquid level is left in the lower end of cover in making, at this moment, flue gas is discharged by going out fume pipe 3, when smoke exhaust ventilator or ventilation fan are not worked, middle cover 1 falls because of action of gravity, middle cover lower end is positioned at sealing fluid, advances fume pipe and is in the liquid seal state, effectively avoids exhaust gases passes to seal in peculiar smell.
