Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] The present invention provides a head-mounted low-resistance anti-active particle respirator, such as figure 1 As shown, it includes a helmet, a face shield and a hollow connector, wherein the face shield is fixed to the helmet by the connector.

[0029] The helmet includes a helmet shell 3, a power source 4, a filter unit 5, an active ventilation unit, and the like. The helmet shell 3 has the function of safety protection. At the same time, it serves as the installation platform for the power supply 4, the filter unit 5 and the active ventilation unit. It can be made of Kevlar composite materials, carbon fiber composite materials, ABS composite materials and other materials, with high strength. , High wear resistance and good flexibility, improve the protective ability and portability of the helmet. The power source 4 can choose rechargeable li...

Abstract

The invention discloses a head-mounted low-resistance active particle prevention respirator. The helmet and mask separated design is adopted, wearing is convenient, the weight is concentrated on the head through the helmet type respirator, compression of the ear hanging type mask on the ears is reduced, and wearing is convenient and stable; the storage state and the use state of the mask can be quickly and conveniently converted, the distance between the mask and the mouth and the nose can be adjusted, and a semi-closed space is formed between the mask and the mouth and the nose. The mask with the bionic structure is adopted, the mask is attached to the face of the human body, the low-resistance filtering device composed of the filtering unit and the active ventilation unit is adopted, active particles and fine particles such as haze are effectively removed, meanwhile, the active ventilation mode is utilized, the breathing resistance is reduced, the comfort of free breathing of the human body is improved, and water vapor cannot be generated on glasses.

Description

technical field [0001] The invention relates to the technical field of breathing masks, in particular to a head-mounted low-resistance anti-active particle respirator. Background technique [0002] In the field of personal protective equipment, most common anti-particulate and anti-haze respirators are passive breathing, that is, relying on mouth and nose breathing to create a pressure difference between the inside and outside of the respirator, forcing the air to pass through the filter element of the respirator to remove harmful particles or haze function of particulate matter. After long-term use of this type of passive particle prevention respirator, the high resistance to breathing and ventilation can easily cause the user to suffer from hypoxia, dizziness and other physical discomfort. [0003] At present, active materials have great potential applications in military and civilian fields, and are the research hotspots of relevant research institutions. The commonly u...
