[0023] The original building is a kitchen structure, including a wall 11 and a roof surface 12. The wall 11 is arranged around the kitchen or on two adjacent sides to separate the kitchen from other rooms. The roof surface 12 is located on the top surface of the kitchen and encloses the kitchen with the wall 11.

[0024] The flue 30 is vertically arranged at the corner of the wall 11, and a circular smoke exhaust hole is arranged on the flue wall on one side thereof, and the diameter of the smoke exhaust hole is 180-200 mm, which is used to exhaust the smoke generated in the kitchen to the outside atmosphere. In this embodiment, the diameter of the smoke exhaust hole on the flue 30 is 180 mm.

[0025] The check valve 40 is a check valve that is flexible to open and close and tightly closed, and is installed on the flue 30. The smoke inlet of the check valve 40 is sealed and connected to the flue 30, and a check valve plate is arranged inside the check valve 40. When exhausting smoke, the check valve plate opens under the push of the smoke, and the smoke enters the flue 30 for exhaust. When not exhausting smoke, the check valve plate automatically closes under the push of gravity and springs, preventing the smoke in the flue 30 from entering the room through the smoke exhaust pipe 50, so the check valve 40 can prevent the smoke in the flue 30 from flowing back into the room.

[0026] The smoke exhaust pipe 50 is a PVC-U pipe with a diameter of 160 to 180 mm. One end of the smoke exhaust pipe 50 is sealed and connected to the check valve 40, and the other end is connected to the range hood for extracting kitchen fumes through an aluminum foil smoke pipe. In this embodiment, the diameter of the smoke exhaust pipe 50 is 160 mm. In addition, in actual application, when the length of the smoke exhaust pipe 50 exceeds 3 meters or the bend exceeds 2 meters, a duct fan needs to be added to the smoke exhaust pipe 50.

[0027] The smoke exhaust pipe 50 is installed and fixed by at least two sets of hanging parts 51. The hanging parts include a hanging rod, an expansion head and a clamp. One end of the hanging rod is vertically installed below the roof surface 12 through the expansion head, and the other end of the hanging rod is used to hang the smoke exhaust pipe 50 above the ceiling 20 through the clamp.

[0028] The suspended ceiling 20 is a light steel keel gypsum board suspended ceiling, which is installed in the original building and arranged below the smoke exhaust pipe 50 to conceal the smoke exhaust pipe 50 and water and electricity pipelines, thereby beautifying the kitchen ceiling.

[0029] The inspection port 60 is provided on the ceiling 20, and its size is 300mm*300mm to 400mm*400mm in length and width. In addition, the inspection port 60 is provided on the ceiling 20 at 50mm near the flue 30, which is more convenient for the inspection and treatment of the check valve. In this embodiment, the inspection port 60 is 400mm in length and 400mm in width.

[0030] A detachable cover plate is provided at the inspection port 60. In normal times, the cover plate covers the inspection port 60; during inspection, the cover plate is opened to inspect and repair the check valve 40.

[0031] <Example 2>

[0032] The flue check valve installation structure is suitable for a kitchen structure and is used to discharge the fumes generated in the kitchen to the outside.

In this embodiment, the diameter of the smoke exhaust hole on the flue 30 is 200 mm.

[0036] The check valve 40 is a check valve that is flexible to open and close and tightly closed, and is installed on the flue 30. The smoke inlet of the check valve 40 is sealed and connected to the flue 30, and a check valve plate is arranged inside the check valve 40. When exhausting smoke, the check valve plate opens under the push of the smoke, and the smoke enters the flue 30 for exhaust. When not exhausting smoke, the check valve plate automatically closes under the push of gravity and springs, preventing the smoke in the flue 30 from entering the room through the smoke exhaust pipe 50, so the check valve 40 can prevent the smoke in the flue 30 from flowing back into the room.

[0037] The smoke exhaust pipe 50 is a PVC-U pipe with a diameter of 160 to 180 mm. One end of the smoke exhaust pipe 50 is sealed and connected to the check valve 40, and the other end is connected to the range hood for extracting kitchen fumes through an aluminum foil smoke pipe. In this embodiment, the diameter of the smoke exhaust pipe 50 is 180 mm. In addition, in actual application, when the length of the smoke exhaust pipe 50 exceeds 3 meters or the bend exceeds 2 meters, a duct fan needs to be added to the smoke exhaust pipe 50.

[0038] The smoke exhaust pipe 50 is installed and fixed by at least two sets of hanging parts 51. The hanging parts include a hanging rod, an expansion head and a clamp. One end of the hanging rod is vertically installed below the roof surface 12 through the expansion head, and the other end of the hanging rod is used to hang the smoke exhaust pipe 50 above the ceiling 20 through the clamp.

[0039] The suspended ceiling 20 is a light steel keel gypsum board suspended ceiling, which is installed in the original building and arranged below the smoke exhaust pipe 50 to conceal the smoke exhaust pipe 50 and water and electricity pipelines, thereby beautifying the kitchen ceiling.

[0040] The inspection port 60 is provided on the ceiling 20, and its size is 300mm*300mm to 400mm*400mm in length*width. In addition, the inspection port 60 is provided on the ceiling 20 at 30mm near the flue 30, which is more convenient for the inspection and treatment of the check valve. In this embodiment, the inspection port 60 is 300mm in length and 300mm in width.

[0041] A detachable cover plate is provided at the inspection port 60. In normal times, the cover plate covers the inspection port 60; during inspection, the cover plate is opened to inspect and repair the check valve 40.

[0042] In addition, in this embodiment, a wall cabinet is provided below the inspection port 60, and a square hole of the same size is opened on the partition plate on the top surface of the wall cabinet opposite to the inspection port 60, and the shelf of the wall cabinet located on the square hole is a detachable movable shelf, and the door of the wall cabinet is a swing door that can be fully opened when necessary to facilitate the inspection of the check valve 40.

[0043] According to the flue check valve installation structure in the above embodiment, it includes the original building body, the suspended ceiling, the flue, the check valve, the exhaust pipe and the inspection port. Among them, the original building body includes the wall body and the roof surface, and the suspended ceiling is also arranged in the original building body, and there is a gap between the suspended ceiling and the roof surface. The flue is arranged at the corner of the wall body, and the flue is provided with a smoke exhaust hole, the check valve is arranged on the smoke exhaust hole, one end of the smoke exhaust pipe is connected with the check valve and is located above the suspended ceiling, and the inspection port is arranged on the suspended ceiling. Based on the flue check valve installation structure, by arranging the inspection port at the corresponding position on the suspended ceiling, when the exhaust pipe and the check valve fail, the exhaust hole and the exhaust pipe can be repaired through the inspection port, which solves the problems of many maintenance procedures, long maintenance time and high maintenance cost of the exhaust pipe and the flue in the prior art, and provides a flue check valve installation structure that is convenient and quick to repair.

[0044] In addition, the smoke exhaust pipe is connected to the roof surface through a hanging piece, and the hanging piece includes a hanging rod, a clamp and an expansion head. One end of the hanging rod is connected to the roof surface through the expansion head, and the other end is connected to the smoke exhaust pipe through the clamp. The smoke exhaust pipe is fixed above the ceiling by the hanging piece.

[0045] In addition, the inspection port is provided with a removable cover. When inspection is needed, the cover can be removed to make the maintenance of the flue and exhaust pipe more convenient.

[0046] Moreover, when a wall cabinet is provided below the inspection port, a square hole is provided at the position corresponding to the inspection port and the top plate of the wall cabinet, so that the ceiling does not need to be dismantled during inspection, so the inspection is more convenient.
