Embodiment 1

[0025] Such as figure 1 , 2 , 3, 4, and 5, a head shield includes an air supply device 1, rectification devices 2 positioned at both sides of the head, the air supply device provides pressure airflow for the rectification device, and the rectification device It includes an air inlet 201 and an air outlet 202 .

[0026] The air supply device is provided with an annular channel 203, the annular channel communicates with the air outlet and the air inlet, and many air outlets are evenly distributed along the circumference of the annular channel, and the airflow passes through the annular channel to evenly distribute the airflow to the air outlets in each direction , so that the air outlets form a radial distribution with the rectification device as the center, and are slightly inclined to the direction of the head, so that the airflows emitted by the rectification devices on both sides converge around the head to form an air curtain 3 surrounding the head, thereby playing a role ...

Abstract

The invention provides a head protection cover, relates to a device for protecting a head, and solves the problem of influence on the activity and comfort of people, of a protection device in the prior art. The head protection cover comprises an air supply device, and rectification devices located at the two sides of the head, wherein the air supply device provides pressure air flow for the rectification devices; each rectification device comprises an intake port and an exhaust port; each exhaust port is radially formed from the center to the surrounding of the head; air flow sprayed from theexhaust ports of the two rectification devices at the two sides of the head forms an air curtain cover surrounding the head; and air flow of an air curtain is capable of effectively protecting the other parts of the head while providing clean air for breathing, so that the head is prevented from being exposed to air containing hazardous substances. In this way, the air curtain does not influence the activity of a wearer; and the head protection cover is breathable, free from influence on sight line, and comfortable in experience.

Description

technical field [0001] The invention belongs to the technical field of health protection equipment, and relates to a head protection device. Background technique [0002] In order to prevent the inhalation of air containing harmful substances, people usually wear masks, but sometimes harmful air can also harm the human body through the corners of the eyes and other parts, so goggles or hoods must be worn. However, these equipments not only have a certain weight, but also have poor ventilation, which seriously affects people's mobility and comfort. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned problems in the prior art, and propose a head protection cover. The head protection cover adopts the air curtain formed by the air flow to surround the head, and as the head protection cover body, it reduces the impact on people. The impact of the action force, good air permeability. [0004] The purpose of the present inve...
