Description

Technical Field

[0001] The utility model relates to the technical field of flue structures, in particular to a flue structure for environment-friendly building design. Background Technique

[0002] In the main flue of high-rise residential buildings, since there are many range hoods discharging lampblack into the main flue in the vertical direction, a large amount of oil stains adhere to the inner wall of the main flue, and it is difficult to clean the main flue. For this reason, in the prior art, a patent document with the publication number of CN111472518B discloses a flue structure for environment-friendly building design, which includes a main flue. A plurality of household flues are connected to the main flue. An exhaust port is arranged at the top of the main flue. Guide columns and a water receiving container are embedded in the main flue. The water receiving container is cylindrical. A steel mesh cylinder is arranged inside the water receiving container. A drain hole is arranged at the bottom of the water receiving container. A valve flap is installed inside the drain hole. An annular brush carrier is arranged outside the water receiving container. A fixing rod is connected between the annular brush carrier and the water receiving container. Brushes are fixed outside the annular brush carrier. A hairspring is arranged on the right side of the exhaust port. A winding disc is installed outside the hairspring. A pull rope is wound around the winding disc. The other end of the pull rope is connected to the upper end of the water receiving container. A cross bar is fixed at the lower end of the main flue. A top column is fixed on the cross bar. The top column is adapted to push open the valve flap. This flue structure for environment-friendly building design is convenient for cleaning the oil stains in the pipeline and can improve the living environment.

[0003] During the actual use process, due to the large height of the main flue, using the annular brush carrier to clean the inner wall of the flue has a high failure rate and hinders the smoke exhaust of the main flue, which is not practical enough. Based on this, the existing flue structure still has the problem of difficult cleaning of internal oil stains and needs to be further improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flue structure for environment-friendly building design to solve the problems put forward in the above background technique.

[0005] To achieve the above object, the present utility model provides the following technical solutions: An exhaust duct structure for environment-friendly building design, including a main exhaust duct and a user exhaust duct. The user exhaust duct is fixedly connected and communicated with the main exhaust duct. A drainage sleeve and a liquid spraying ring are respectively fixedly installed on the inner wall of the main exhaust duct. The drainage sleeve includes a central cylinder and a conical bottom shell. The conical bottom shell is fixedly connected to the inner wall of the main exhaust duct. The central cylinder is fixedly installed at the upper opening of the conical bottom shell. The conical bottom shell divides the inner cavity of the main exhaust duct into upper and lower two chambers. A plurality of water filtering holes penetrating up and down are opened at the bottom of the conical bottom shell. A sewage discharge pipe is arranged in the main exhaust duct. The sewage discharge pipe passes through the central cylinder. A connecting pipe is fixedly installed on the surface of the sewage discharge pipe. The upper chamber of the conical bottom shell is communicated with the sewage discharge pipe through the connecting pipe. The liquid spraying ring sprays cleaning liquid onto the inner wall of the main exhaust duct to clean the oil stain. Since multiple layers of drainage sleeves can be arranged in the main exhaust duct, the oil stain will not directly fall in the main exhaust duct, avoiding high-rise users from cleaning the oil stain and polluting the exhaust ducts of lower-level users, which provides convenience for segmentally cleaning the oil stain in the main exhaust duct.

[0006] In some embodiments, the liquid spraying ring is arranged on the upper side of the central cylinder. A liquid supply pump is fixedly installed on the outer side of the main exhaust duct. The liquid supply pump is communicated with the liquid spraying ring through a pipeline. A plurality of first nozzles and a plurality of second nozzles are respectively fixedly installed on the surface of the liquid spraying ring. The outlet end of the first nozzle is inclined upward, and the outlet end of the second nozzle faces the inner wall of the main exhaust duct. The cleaning liquid is sprayed into the main exhaust duct through the first nozzle and the second nozzle.

[0007] In some embodiments, one end of the connecting pipe away from the sewage discharge pipe extends to the conical surface of the conical bottom shell. The position of the inlet end of the connecting pipe is higher than the position of the water filtering hole. The cleaning liquid falls from the filtrate hole to the inner wall of the lower main exhaust duct, making it difficult for the oil stain to adhere to the inner wall of the transfer exhaust duct.

[0008] In some embodiments, an anti-backflow component is slidably installed inside the user exhaust duct, and the opening and closing of the user exhaust duct are controlled by the anti-backflow component.

[0009] The anti-backflow component includes a movable plug. The movable plug is slidably installed inside the user exhaust duct. Among them, a limiting groove is opened inside the user exhaust duct. A limiting block is fixedly installed on the outer surface of the movable plug. The limiting block is slidably arranged in the limiting groove.

[0010] A transmission shaft is slidably installed inside the movable plug. A cover plate is fixedly installed at the end of the transmission shaft. A smoke exhaust hole is opened at the end of the movable plug. An installation cavity is opened inside the movable plug. Two springs are arranged inside the installation cavity. A sliding ring is fixedly installed on the surface of the transmission shaft. The sliding ring slides along the inner wall of the installation cavity, and the two springs respectively abut against both sides of the sliding ring.

[0011] An electric telescopic rod is fixedly installed on the surface of the user flue. The telescopic end of the electric telescopic rod extends into the user flue, and a transmission connecting rod is rotatably installed at the telescopic end of the electric telescopic rod. The end of the transmission connecting rod is rotatably connected to the end of the transmission shaft. The electric telescopic rod expands and contracts to drive the transmission shaft to expand and contract, driving the cover plate to move, controlling the opening and closing of the user flue, preventing the oil fume in the main flue from flowing back into the user flue through the smoke exhaust hole, making the flue structure have an anti-backflow effect and being more environmentally friendly.

[0012] Beneficial effects

[0014] 1. In this flue structure, by arranging a liquid spraying ring, a drainage sleeve and a sewage discharge pipe in the main flue, the liquid spraying ring sprays cleaning liquid onto the inner wall of the main flue, the drainage sleeve intercepts the oil stains being cleaned, and then discharges them through the sewage discharge pipe, avoiding high-rise users from cleaning the oil stains and polluting the flues of lower users, facilitating the segmented cleaning of the oil stains in the main flue. This design has a simple structure, no excessive transmission mechanisms, is safe and reliable, and is more practical.

[0015] 2. In this flue structure, by arranging an anti-backflow component, when exhausting smoke, the flue gas enters the main flue through the smoke exhaust hole, and after use, the cover plate covers the opening of the smoke exhaust hole, preventing the oil fume in the main flue from flowing back into the user flue through the smoke exhaust hole, making the flue structure have an anti-backflow effect and being more environmentally friendly.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: an exhaust duct structure for an environment-friendly building design, including a main duct 1 and a user duct 2. The user duct 2 is fixedly connected and communicated with the main duct 1. A drainage sleeve 3 and a liquid spraying ring 4 are respectively fixedly installed on the inner wall of the main duct 1. The drainage sleeve 3 includes a central cylinder 5 and a conical bottom shell 6. The conical bottom shell 6 is fixedly connected to the inner wall of the main duct 1. The central cylinder 5 is fixedly installed at the upper opening of the conical bottom shell 6. The conical bottom shell 6 divides the inner cavity of the main duct 1 into upper and lower two chamber rooms. A plurality of water filtering holes 7 penetrating up and down are opened at the bottom of the conical bottom shell 6. A sewage discharge pipe 8 is arranged in the main duct 1. The sewage discharge pipe 8 passes through the central cylinder 5. A connecting pipe 9 is fixedly installed on the surface of the sewage discharge pipe 8. The upper chamber of the conical bottom shell 6 is communicated with the sewage discharge pipe 8 through the connecting pipe 9. Among them, one end of the connecting pipe 9 far from the sewage discharge pipe 8 extends to the conical surface of the conical bottom shell 6, and the inlet end position of the connecting pipe 9 is higher than the position of the water filtering holes 7.

[0023] The liquid spraying ring 4 is arranged above the central cylinder 5. A liquid supply pump 10 is fixedly installed on the outside of the main duct 1. The liquid supply pump 10 is communicated with the liquid spraying ring 4 through a pipeline. A plurality of first nozzles 11 and a plurality of second nozzles 12 are respectively fixedly installed on the surface of the liquid spraying ring 4. The outlet end of the first nozzle 11 is inclined upward, and the outlet end of the second nozzle 12 faces the inner wall of the main duct 1.

[0024] In this embodiment, an anti-backflow component is slidably installed inside the user duct 2, and the opening and closing of the user duct 2 are controlled by the anti-backflow component.

[0025] Specifically, the anti-backflow component includes a movable plug 13. The movable plug 13 is slidably installed inside the user duct 2. A limiting groove 18 is opened inside the user duct 2. A limiting block 19 is fixedly installed on the outer surface of the movable plug 13. The limiting block 19 is slidably arranged in the limiting groove 18.

[0026] A transmission shaft 14 is slidably installed inside the movable plug 13. A cover plate 15 is fixedly installed at the end of the transmission shaft 14. A smoke exhaust hole 23 is opened at the end of the movable plug 13. An installation cavity is opened inside the movable plug 13. Two sections of springs 16 are arranged in the installation cavity. A sliding ring 17 is fixedly installed on the surface of the transmission shaft 14.
