A filter cartridge 105 is installed in the purification chamber 103 to correspond to the fan 600, and the air in the purification chamber 103 is first filtered by the filter cartridge 105 before passing through the fan 600, and then passes through the outlet 102 to be transported to the mask 120 for the user to breathe.

[0030] The mask 120 is provided with an exhaust port 123, and an exhaust module 124 is installed in the exhaust port 123. The exhaust module 124 in this embodiment is tubular, one end of the exhaust module 124 is connected to the exhaust port 123, and the other end of the exhaust module 124 is extended into the mask 120 so as to be positioned corresponding to the user's nose and mouth.

When the user exhales or speaks, the sheet 125b is blown toward the outlet end 124b of the exhaust module 124, and opens to facilitate exhaust and facilitate the transmission of voice from the mask 120. When the user exhales, the sheet 125b is sucked toward the grill 125a and is tightly fitted to close the grill 125a.

[0031] The replaceable purification module 400 is provided with corresponding functions according to the requirements of use. Specifically, the electric sterilization kit refers to a kit that is driven by being energized and autonomously purifies the air passing through it, and the electric sterilization kit can be electrically connected to the docking module 110 and is powered by the docking module 110.

The cassette 401 has an opening for passing air, and the conductive sheets 411a are arranged in parallel at intervals, and the air passes through the gaps between the conductive sheets 411a. The touch structure of the high-pressure sterilization kit 410a is a first touch structure 402a, and the conductive contact point group of the high-pressure sterilization kit 410a is a first conductive contact point group 403a. In this embodiment, the first touch structure 402a is a bump protruding from the outside of the bottom of the cassette 401 of the high-pressure sterilization kit 410a, and the first conductive contact point group 403a extends from any two conductive sheets 411a and protrudes from the cassette 401, but the present invention is not limited thereto. After the autoclave sterilization kit 410a is inserted into the replacement socket 104, its first touch structure 402a can activate the corresponding first indicator switch 112a to light up the corresponding first indicator light 111a, thereby indicating the placement status of the replaceable purification module 400. The first conductive contact points 403a can be docked with the first electrode group 113a and the second electrode group 113b, respectively, and are thus electrically connected to the high voltage generator 520 shown in FIG. 4 to output a high voltage to each conductive sheet 411a. When air passes through the gaps between the conductive sheets 411a, the voltage of the conductive sheets 411a can eliminate pathogens in the air.

[0035] 11 and 12, another type of electric sterilization kit may be a negative ion sterilization kit 410b. The negative ion sterilization kit 410b includes a cassette 401, at least one negative ion brush 411b, at least one brush holder 412b corresponding to the negative ion brush 411b, and a sub-circuit board 413b.

After the negative ion sterilization kit 410b is inserted into the replacement socket 104, its second touch structure 402b can activate the corresponding second indicator switch 112b to light up the corresponding second indicator light 111b, thereby indicating the placement status of the replaceable purification module 400.The second conductive contact group 403b can be docked with the corresponding second electrode group 113b to supply power to the negative ion brush 411b. When air passes through the negative ion sterilization kit 410b, the negative ions generated by the negative ion brush 411b oxidize and eliminate pathogens in the air. In this embodiment, the brush holder 412b is a cylinder, so that the negative ion brush 411b can be directly inserted into the brush holder 412b, making installation easy.

Generally, the standard of the high-efficiency filter 421c refers to a filter having a filtering effect of more than about 99.97% for particles with a particle size of 0.3 μm. The touch structure of the filter kit 420c is a third touch structure 402c. In this embodiment, the third touch structure 402c is a bump protruding from the outside of the bottom of the cassette 401 of the filter kit 420c, but the present invention is not limited thereto. After the filter kit 420c is inserted into the replacement socket 104, the third touch structure 402c can activate the corresponding third indicator switch 112c, which lights up the corresponding third indicator light 111c. This indicates the arrangement state of the replaceable purification module 400.
