Abstract

The invention belongs to the technical field of oxygen production equipment, and particularly relates to a mask with an oxygen production device. The mask comprises a mask main body and the oxygen production device fixedly mounted on the mask main body, a communicating hole is formed in the mask main body, the oxygen production device is in communication with the inner wall of the mask main body through the communicating hole, a reaction bin and a mounting plate are mounted in a shell, a one-way airflow cylinder is installed in a through hole, a plurality of communicating pipes are installed on the outer wall of the shell and communicate with the reaction bin and the inner wall of the mask main body, and one-way valves are installed in the communicating pipes. The mask aims to convert water vapor and carbon dioxide exhaled by a human body into oxygen through an oxygen production agent in a reaction bin to be supplied to a user for breathing, oxygen can be supplied to a user for a longer time, gas exchange does not exist between the mask and the outside, sticky floating objects can be prevented from adhering to a filter pad of a filter type self-rescue mask, resistance is increasedwhen the mask is used by the user, the dyspnea is caused, and meanwhile, the size and the mass of the mask are small, the service life is long, and regular maintenance is not needed.

Description

technical field [0001] The invention belongs to the technical field of oxygen-generating equipment, and in particular relates to a mask with an oxygen-generating device. Background technique [0002] The mask is a portable respiratory protective device for people entering the well or protecting personnel to prevent the human body from inhaling harmful gas poisoning or hypoxia suffocation when fires, gas, coal dust explosions and other accidents occur underground or in special environments. Its main purpose is to wear it for users to avoid danger from poisoning or suffocation when various accidents occur; it is suitable for marine ships, underground railways, harmful gas storage warehouses, entertainment venues, large shopping malls and high-rise residential buildings and other places. In order to meet the requirements of escape and rescue in special environments, many countries in the world have increased the research on various masks, and gradually developed a variety of fi...
