Abstract

The invention provides a novel exhaust pipeline. An exhaust head is detachably connected to the air outlet end of a pipe body. A fan is arranged in the pipe body. An external pipe is arranged in the position, between the exhaust head and the fan, of the pipe body and connected with an end cover through a thread. A filter screen is detachably connected to the end cover. An air blocking cushion, a connecting rod and a sealing cover are sequentially connected to the upper end of the filter screen from bottom to top. The air blocking cushion covers the space between the pipe body and the external pipe. The novel exhaust pipeline has the following advantages that the pipeline firmness is good, replacement of the filter screen can be achieved, exhausted gas is cleaner after being subjected to filtering, and the condition in the pipeline can be observed through an observation window so that the filter screen can be replaced in time.

Description

technical field [0001] The invention belongs to the field of pipelines, in particular to a novel exhaust pipeline. Background technique [0002] In various public places such as office buildings and residential buildings, indoor natural ventilation is poor. Harmful substances from decoration materials, waste gas produced by the human body, mold produced by objects, etc., will cause indoor air pollution. The most effective way to solve indoor air pollution is natural ventilation and opening doors and windows, but outside noise, dust and polluted air will enter the room. Especially in summer, the indoor windows are closed tightly, and the indoor air is even more dirty. If you open the windows, hot air will come in in summer, and cold air will come in in winter, making people feel uncomfortable. Even in the lukewarm spring and fall months, opening the windows would blow in dust, which again made cleaning a problem. At present, the cost of ventilation devices in public places...
