Half face mask with regulation thermal stability system for continuous air flow: Stabimask

This article presents the design and prototyping of an electronic mask as personal protective equipment for the virus pandemic known as COVID – 19. Needs were identified such as: tightness and comfort. Requirements for use for long periods of time; this was considered for the design, also it has an adjustable ventilation system. The mask was simulated and validated with Solidworks Flow Simulation software, in addition a PID control model was implemented, thereby, it was shown that enough flow is generated to vary the temperature in a range of 20 to 37.2 ° C inside the mask. The design considers an outlet duct and an inlet duct with filters that prevent the entry of polluting particles, providing adequate protection. The prototype was made by 3D printing, And the thermal stability was achieved with the implementation of the temperature regulation system. The results obtained were validated, and they allow to future research to provide greater efficiency to masks.
