Sterilizing mask capable of adjusting air flow

Abstract

The invention relates to the technical field of emergency protection, and discloses a sterilization mask capable of adjusting air flow. The mask comprises a mask body, wherein the mask body comprisesa composite filter membrane on the outermost layer; a polymer framework is arranged on the inner side of the composite filter membrane; headbands are arranged on the edges of the upper side edge and the lower side edge of the polymer framework; a silica gel mask is arranged on the edge of the inner side of the polymer framework; a sterilization mechanism is arranged on the inner side of the silicagel mask; a fan assembly is arranged on the inner side of the sterilization mechanism; and a one-way air outlet valve penetrates through one side of the middle part of the mask body. According to theinvention, the sterilization mechanism is matched with the fan assembly, an ultrasonic atomization module can atomize a disinfectant in a liquid containing bottle, the fan assembly can increase the outside air suction force of the mask, a micro motor drives turbofan blades to rotate to achieve air suction, the micro motor achieves rotation speed adjustment through a switch on the circuit board, and therefore, the air inflow is adjusted, and human respiration is facilitated.

Description

technical field [0001] The patent of the present invention relates to the technical field of emergency protection, in particular, to a sterilizing mask with adjustable gas volume. Background technique [0002] A mask generally refers to a device worn on the nose and mouth to filter the air in and out of the nose and mouth, so as to block harmful particles and droplets from entering and exiting the wearer's mouth and nose. It is mostly made of non-woven fabric and other filter materials. Progress, the protective mask used for droplet filtration uses the melt-blown layer as a filter material for filtering droplets and carrying pathogenic bacteria particles. The principle is to use the electrostatic adsorption of the melt-blown layer. Exposure to water vapor or excessive humidity leads to reduced or invalid filtering effect, and users cannot intuitively judge the failure of the protective effect and it is difficult to achieve long-term storage and reuse. At the same time, the e...

Problems solved by technology

[0004] The purpose of the present invention is to provide a sterilizing mask with adjustable air volume. By cooperating with the sterilizing mechanism and the fan assembly, the ultrasonic atomization module can atomize the disinfectant inside the liquid bottle and contact with the air to realize sterilization As a result, the fan assembly can increase the suction force of the mask to the external air, the micro motor drives the vortex fan blade to rotate to achieve air inhalation, and the micro motor realizes the speed adjustment through the switch on the circuit board, so as to realize the adjustment of the intake air volume, which is convenient for human breathing. It aims to solve the problem that the existing masks have good protective effects due to the multi-layer filter material, but the breathing resistance of the user is too large when worn for a long time, which will increase the breathing burden
