Respiratory protection testing machine

Abstract

The invention discloses a respiratory protection testing machine. The respiratory protection testing machine comprises a dry vacuum pump, an observation bin, a dust generating roller, a mixed jet device, a diffusion fan, a first head mold, a second head mold, a displayer and a controller. The dust generating roller, the mixed jet device, the diffusion fan, the first head mold and the second head mold are all arranged in the observation bin; the dry vacuum pump and the dust generating roller are both connected with the mixed jet device through pipes, and the diffusion fan is arranged in the emitting direction of the mixed jet device; the first head mold and the second head mold are connected with breathing simulators through throat pipes, and a mask or a protective mask is worn on the firsthead mold; the display and the respiration simulators are electrically connected with the controller. According to the invention, the field operation environment can be simulated, and a contrast experiment is carried out to fully illustrate the necessity and importance of wearing a mask or a protective mask, so the protection consciousness of personnel is improved.

Description

technical field [0001] The invention belongs to the technical field of respiratory protection testing equipment, and more specifically relates to a respiratory protection testing machine. Background technique [0002] Air pollutants are harmful to the human body in many ways, mainly manifested as respiratory diseases and physiological dysfunction, as well as diseases caused by stimulation of mucous membrane tissues such as eyes and noses. When the concentration of pollutants is high, it will cause acute pollution poisoning. The protection against respiratory diseases is already in a state of urgency, but in reality, people cannot pay enough attention to it. In the current market, when the working environment is polluted, calling on personnel to wear masks or protective masks can effectively reduce the occurrence of respiratory diseases, but relevant personnel do not pay enough attention, and the benefits of wearing masks or protective masks cannot be visualized.
