Abstract

The utility model discloses a flexible double-layer air duct, which comprises a flexible air duct main body, wherein the flexible air duct main body is formed by compounding outer polyurethane foam and inner glass wool, a dew prevention mechanism and a leakage prevention mechanism are respectively arranged on the flexible air duct main body, the dew prevention mechanism comprises interlayer cloth, the interlayer cloth is arranged on the inner wall of the flexible air duct main body, silica gel is arranged in an inner cavity of the interlayer cloth, and a first zipper belt is arranged between the left opening of the interlayer cloth and the inner wall of the flexible air duct main body. The device solves the problems that the existing flexible air pipe material generally does not have a moisture absorption function and cannot effectively adjust the humidity in the pipeline. In some high humidity environments, such as basements, bathrooms or industrial plants, moisture in the air is easy to condense on the inner wall of the air pipe, so that bacteria and mold are bred in the air pipe, and even pipeline materials are corroded, and the service life of the air pipe and the air quality are affected.

Description

Flexible double-layer air pipe Technical Field The utility model belongs to the technical direction of flexible air pipes, and particularly relates to a flexible double-layer air pipe. Background Ventilation ducts are important devices for ventilation and conditioning in buildings, industry and business. The conventional ventilating duct is mainly made of metal or hard plastic, and although the ventilating duct has excellent strength and durability, the problem of insufficient flexibility is increasingly highlighted in some special occasions such as environments where frequent adjustment of the layout of the duct is required or installation space is limited. Therefore, the flexible air duct is capable of adapting to complex installation environments and is convenient to install and adjust. However, existing flexible ductwork have some limitations in use. The existing flexible air duct material generally has no moisture absorption function and cannot effectively adjust the humidity in the pipeline. In some high humidity environments, such as basements, bathrooms or industrial plants, moisture in the air is easily condensed on the inner wall of the air duct, which causes bacteria and mold to grow inside the air duct, even corrodes the duct materials, and affects the service life and air quality of the air duct. This phenomenon is a problem to be solved by those skilled in the art. Disclosure of utility model The utility model aims at solving the problems in the background technology by aiming at the flexible double-layer air pipe of the prior device.
