[0002] With the increasing demands for medical care, industrial safety, and personal protection, breathing masks, as an important protective device, are widely used. However, traditional breathing masks often cause discomfort when worn, mainly because the fixing method between the headband and the mask body is not flexible enough and cannot automatically adjust the fitting degree according to the size of the user's head shape, resulting in insufficient sealing or uncomfortable wearing. In addition, some current breathing masks use elastic bands made of elastic materials to adapt to different head sizes. Due to the elastic tension of the elastic band, wearing the breathing mask for a long time may cause unnecessary pressure on the face, affecting the comfort and health of the user.

[0024] Specifically, the embodiment of the present application is ingeniously designed and novel in structure. The headband assembly is composed of an upper headband body 2 and a lower headband body 3, which are respectively slidably inserted into the upper headband sliding groove 5 and the lower headband sliding groove 6 of the mask body 1 and connected to the headband positioning housing 4. Further, the sensor assembly is located inside the mask body 1 and is used to monitor the pressure state of the contact between the mask and the face. Then the controller 17 receives data from the sensor assembly and adjusts the tension of the headband by driving the tension adjustment mechanism based on a preset pressure threshold, so as to maintain the best mask fitting degree.
