Novel multi-effect outer wall air inlet pipe and use method thereof

Abstract

The invention discloses a novel multi-effect outer wall air inlet pipe comprising a pipe body, a positioning flange and a seal ring. A telescopic flexible hose is arranged between the pipe body and the positioning flange. The inner pipe wall of the pipe body is a reducing pipe wall. Multiple silencing holes are evenly distributed in the inner wall pipe and are filled with silencing cotton. A grating piece is arranged at an air inlet. The rear end of the grating piece is connected with the air inlet in a threaded manner. Three to five inclined blades are arranged at the front end of the grating piece. A first roughening ring and a second roughening ring are arranged on the outer surface of the pipe body. A protection layer is arranged on the outer wall of the pipe body and comprises a nanometer anti-corrosion coating, a heat preservation layer and an anti-corrosion waterproof coating. By means of the novel multi-effect outer wall air inlet pipe, noise generated when air enters the pipe body can be reduced; the protection layer is arranged, the corrosion prevention function, the heat preservation function and the waterproof function of the outer wall of the pipe body are improved, the effects of slowing down aging of the outer wall of the pipe body and reducing rainwater invasion are achieved, and the service life of the air inlet pipe can be prolonged; and backward pouring of rainwater or invasion of mosquitoes can be prevented, accumulation of foreign matter in the pipe body can be avoided, and maintenance of the interior of the pipe body in the later period can be reduced.

Description

technical field [0001] The invention belongs to the technical field of building air ducts, in particular to a novel multi-effect external wall air inlet duct. Background technique [0002] Some ventilating equipment used in households, such as air purifiers, air conditioners, etc., need to punch holes on the wall near the placement position before installing the ventilation ducts. During installation, the fixing of the outside of the ventilation duct requires the operator to operate outdoors. In order to ensure the safety of the work, the operator needs to take safety measures before proceeding. However, for the installation of some high-rise buildings, there are still certain safety hazards for the operator. affect its work efficiency. Therefore, someone in the industry has developed an air duct that does not require outdoor installation. The entire installation process can be carried out directly indoors, which is easy to operate and reduces potential safety hazards. [...

AI Technical Summary

Problems solved by technology

[0003] However, when this type of air duct is in use, it is easy to generate noise in the pipe, which affects the living or working environment of people; and after the air duct is used for a long time due to the aging of the outer wall of the pipe, it is easy to cause the intrusion of external rainwater or humid air. If things go on like this, rainwater or Moist air will seep into the inner wall of the wall, destroying the decorative layer of the inner wall and the structural layer of the wall; in addition, although the outer ends of some ventilation ducts are equipped with rain-proof covers, the rain will still flow when the wind is heavy and the rain is heavy. Into the ventilation duct, causing water accumulation or even backflow, affecting the normal operation of the ventilation equipment
