Mask breathing control method and mask

The invention provides a breathing control method for a mask and a mask, The method includes the steps of preset a first mapping database corresponding to user physical sign data and fan rotation data; Obtain the user's physical sign data based on the sensor component of the mask; Based on the first mapping database and the user's physical sign data, Obtaining corresponding first rotation data; controlling the fan of the mask based on the first rotation data; This application realizes the adaptive adjustment of fan rotation parameters according to the current state of the user. It improves the breathing comfort of the user when wearing the mask, and meets the user's breathing comfort demand when wearing the mask in multiple scenarios.
