Positive-pressure air guiding tube having function of convenient suspension

Abstract

The invention relates to the technical field of positive-pressure air guiding tubes, in particular to a positive-pressure air guiding tube having a function of convenient suspension. The positive-pressure air guiding tube comprises a base layer; the outer side of the base layer is coated with a heat-insulating layer; the outer side of the heat-insulating layer is coated with an anti-static coating; a first flame-retardant layer is arranged on the outer side of the anti-static coating; a plurality of accommodating cavities are evenly formed inside the first flame-retardant layer and contain flame retardants; the outer side of the first flame-retardant layer is coated with a second flame-retardant layer. The positive-pressure air guiding tube has the beneficial effects as follows: under theeffect of the attraction force of a first magnetic pole and a second magnetic pole, a first semi-circular ring and a second semi-circular ring can be clamped firmly, the positive-pressure air guidingtube can be fixed, then a hook penetrates through a second through hole, and the positive-pressure air guiding tube can be suspended. By the aid of the suspension device, the positive-pressure air guiding tube can be suspended quickly, the influence of the length of the positive-pressure air guiding tube on the suspension position can be avoided, the positive-pressure air guiding tube can be suspended conveniently and flexibly, and thus the suspension device has the wide popularization and application values.

Description

technical field [0001] The invention relates to the technical field of a positive pressure air guide, in particular to a positive pressure air guide with a convenient hanging function. Background technique [0002] The air duct, also known as the ventilation pipe, is a flexible pipe that guides the air flow along a certain direction. At present, there are first-generation rubber-coated air ducts, third-generation plastic-coated air ducts and third-generation vertical and horizontal non-woven ducts in China. Sewing dryer. Air ducts are divided into positive pressure ducts and negative pressure ducts. The difference between the two is that there is no skeleton in the middle of the positive pressure ducts; while the negative pressure ducts are composed of countless steel rings of the ducts, also commonly known as skeleton ducts. The air outlet of the positive pressure air duct is to blow air outside, while the air outlet of the negative pressure air duct is to suck air inward....

AI Technical Summary

Problems solved by technology

[0003] When the positive pressure air guide tube is in use, in order not to take up space, it is generally installed on the top. At this time, a connecting piece is required to fix it. The existing connecting piece is generally formed directly with the air guiding tube during manufacture. When the length of the air guide tube is adjusted, the original connectors cannot be used, resulting in the suspension of the air guide tube
