When the filter element 5 is installed, the main body part of the filter element 7 is directly inserted into the shell 6 from the filter element inserting seam 10, and the convex edge 11 of the filter element 7 is clamped on the filter element inserting seam 10, so that the filter element 7 is not easy to fall off from the shell 6; because the filter element inserting seam 10 is positioned between the ventilating opening 8 and the ventilating hole 4, the main body part of the filter element 7 is positioned between the ventilating opening 8 and the ventilating hole 4 after being inserted into the shell 6. When the filter element 7 needs to be replaced or cleaned, a user can directly pull the convex edge 11 of the filter element 7 by hand to detach the filter element 7 from the filter element insertion slot 10 of the shell 6. Therefore, the filter element 7 on the breather valve 3 of the embodiment is convenient for people to mount and dismount.

As shown in fig. 2, a sensor assembly 12 is further disposed at the position of the ventilation hole 4 on the inner side of the mask body 1, and the sensor assembly 12 includes various sensors, such as a temperature sensor and/or a respiratory airflow sensor, so that the sensor assembly 12 can be used for measuring the gas data of the person during breathing, for example, measuring the temperature data of the exhaled gas of the person by using the temperature sensor, and/or measuring the respiratory frequency data of the person by using the respiratory airflow sensor. The above-mentioned measuring the temperature data of the exhaled air of the person by using the temperature sensor and/or measuring the respiratory frequency data of the person by using the respiratory airflow sensor is the prior art, and is not described herein again.

The cover body 1 is further provided with a controller (not shown in the figure) and a wireless communication module (not shown in the figure) used as an alarm module, the controller and the wireless communication module can be fixedly installed on the sensor assembly 12, so that the sensor assembly 12, the controller and the wireless communication module can be integrally installed and disassembled, the controller is respectively connected with the sensor assembly 12 and the wireless communication module, the sensor assembly 12 sends the measured gas data to the controller, and the controller acquires whether to make the wireless communication module give an alarm according to the gas data, specifically, taking a temperature sensor arranged on the sensor assembly 12 as an example: under the condition that the mask is worn by a person and the health condition of the person is normal, the temperature data measured by the temperature sensor is within the normal body temperature range (36.3-37.2 ℃) of the human body; if the temperature data is higher than 37.2 ℃, the controller knows that the mask is worn by a person and the health condition of the person is in problem, so that the wireless communication module sends alarm information to the outside; if the temperature data is lower than 36.3 ℃, the controller knows that the mask is not worn, and therefore the wireless communication module sends out alarm information to the outside. Taking the respiratory airflow sensor on the sensor assembly 12 as an example: when the mask is worn by a person and the health condition of the person is normal, the respiratory frequency data measured by the respiratory airflow sensor is within the normal respiratory frequency range (12 times/minute-20 times/minute) of the human body; if the respiratory frequency data is higher than 20 times/minute or lower than 12 times/minute, the controller knows that the mask is worn by a person and the health condition of the person is in a problem, so that the wireless communication module sends out alarm information to the outside and the LED lamp bar 9 emits light to give an alarm; if the breathing airflow sensor does not detect the breathing frequency data, the controller knows that the mask is not worn, so that the wireless communication module sends out alarm information to the outside, and the LED lamp bar 9 emits light to give an alarm. Therefore, the outside can know the wearing condition of the mask and/or the health condition of people according to whether the wireless communication module sends out alarm information or not so as to take measures for people who do not wear the mask and take measures for people after people infect respiratory infectious diseases, thereby reducing the risk of spreading respiratory infectious diseases.
