Another example is the utility model patent with the publication number CN207544378U, which proposes a mask, which includes a cover outer shell and a cover inner shell, and the cover outer shell and the cover inner shell cooperate with each other to form the mask body of the mask; the mask also It includes a sensor and a wireless transceiver element assembled in the cover; the sensor analyzes the target gas entering the mask to obtain an air quality index; the wireless transceiver element transmits the air quality index analyzed by the sensor to a The user's terminal device; by using the above-mentioned mask, the wireless transceiver element can transmit the air quality index obtained by the sensor analysis to the user's terminal device in real time for the user to observe and understand the quality of the inhaled air in real time.

Another example is the utility model patent with the announcement number CN209420996U, which proposes a mask that can detect breathing signals in real time, and relates to the field of flexible wearable devices. Among them, this mask includes a mask body, a humidity sensor and a signal processor. A humidity sensor, fixed on the mask body, includes a humidity sensing fiber and electrode wires fixedly connected to both ends of the humidity sensing fiber. The signal processor, fixed on the mask body, includes a signal acquisition module, a signal processing module, a wireless signal transmission module, a power supply module and a signal display module connected in sequence, and is used to convert the signal output by the humidity sensor into visual data. The mask provided by the utility model can be used repeatedly for many times, and can detect the changes of humidity around the nasal cavity and the oral cavity caused by breathing in real time, so as to obtain information such as breathing depth, breathing frequency and respiratory arrest.

After search and analysis, the applicant found that these mask technologies are all used to detect various types of breathing data of the human body, or to detect air quality, and have no further innovative functional applications. The applicant found that: with the improvement of people's living standards, the public hopes to lose weight through physical exercise.
