Connecting and placing hidden type design method for gas guide tube of separating type electric face mask

Abstract

A separating type electric face mask with a hidden gas guide tube consists of a face mask, a gas guide tube and a mainframe, wherein the mainframe consists of an air filter plate, an air exhaust fan,a power supply and an enclosure; the gas guide tube is connected to the face mask in a hidden mode; when the gas guide tube is taken as a hanging rope, the gas exhaust tube is also suspended on a bodyfor hiding the gas guide tube; or back clothing is suspended on the mainframe, so that the gas guide tube does not have the effect of being placed in front of a body to hide, and the gas guide tube is not placed in front of the body to affect life and behavioral habits of people.

Description

technical field [0001] The invention relates to an electric mask, in particular to an electric fan air-supply mask connected to an air filter device (also called a host) by an air duct. Background technique [0002] Masks are self-protection tools that people wear on their faces to provide filtered fresh air due to changes in the surrounding environment. Masks are functionally divided into mechanical suction masks and electric active air supply masks. Electric active air supply masks refer to masks that use batteries to make fans blow air. Electric active air supply masks are divided into two types, one is to install the electric fan directly on the mask, and the other is to separate the filter device (also called filter purifier or host) from the mask, and there is an air duct connection between them. [0003] The separate electric mask is composed of a filter purifier (also known as the host), an air duct and a mask, and the filter purifier is composed of a filter elemen...

AI Technical Summary

Problems solved by technology

The separate electric mask has a good filtering effect, but it has disadvantages: First, the mask is troublesome to wear and use, and there is a trachea on the face when it is used, which is relatively prominent and protruding, which is inconvenient to move and does not conform to people's living habits

The second is that one end of the airway is suspended on the face mask and in front of the face, the head is constantly twisting, the airway swings around the neck as the center, and the force of the airway to pull the mask is large, which is uncomfortable and natural to wear.

The third is that the airway between the mask and the host is long, and the host connected to the other end of the airway is set on the arm, the head swings a lot, and the force of the airway to pull the mask is large, which is uncomfortable and natural to wear.

To sum up, the airway is suspended in front of the body, the force of swinging and pulling the mask is large, the wearing experience is poor, and people's work and living habits are restricted
