A mask internal pressure control method and system and a respirator, relating to the technical field of respirators. The control method comprises: providing a fan on a mask, and when the fan is started, continuously supplying airflow into the mask; determining a correlation between the rotating speed of the fan, a pressure value in the mask, and a respiratory behavior of a user; and in the working process, controlling the rotating speed of the fan on the basis of the pressure value collected in real time and the correlation. When the fan is started, the airflow is continuously supplied into the mask, and the rotating speed of the fan is dynamically adjusted on the basis of the collected pressure value and the determined correlation, so that the system can adjust airflow supply according to a real-time requirement of the user so as to reduce the respiratory resistance to the maximum extent. The pressure control method has the advantages of providing a personalized and real-time ventilation solution that can be adjusted according to a specific respiratory requirement of the user, thereby effectively handling the respiratory resistance.

 Appl.No 23762005 Applicant DYSON TECHNOLOGY LTD Inventor HOVELL BENJAMIN

A wearable air purifier, comprising a headgear, an air delivery mask connected to the headgear and which bounds an air delivery region, an airflow generator configured to direct airflow to the air delivery region through the air delivery mask. The headgear defines an airflow path which is defined at least in part by a head-engaging surface. Beneficially, the airflow generator is configured to direct air through the airflow path to cool the head-engaging surface. An advantage of the invention is that the wearable air purifier is configured to cool the head region of the user/wearer by way of the airflow that passes through the airflow path which is in part defined by the head-engaging surface. This provides enhanced comfort for the user during periods of prolonged wearing.
