Detailed Description

The invention is further illustrated by the following specific examples:

as shown in fig. 1, 2 and 3, the combined multifunctional protective mask comprises a mask body and an air purification box, wherein the mask body 1 is in a general mask shape, and the inner edge of the mask body can be hermetically designed to be better hermetically attached to the face of a human body. The cover body 1 is provided with an air inlet 11 and an exhaust valve 12, the air inlet 11 is used for feeding fresh air from the air purification box 2, and the exhaust valve 12 is used for exhausting carbon dioxide exhaled by a human body.

The air purification box 2 comprises two chambers, namely a pump chamber 21 and a water storage chamber 22, wherein an air pump 4, a battery 8 and a power supply circuit are arranged in the pump chamber 21, the battery drives the air pump to operate through the power supply circuit, and a switch 25 is arranged on the power supply circuit. One end of an air inlet 31 of the air inlet pipeline 3 is arranged on the side wall of the pump chamber 21 and is communicated with the outside air, and a coarse filter screen can be arranged on the air inlet 31 to perform coarse filtration on the outside air for the first time, and the coarse filter screen can be used as gauze. The air inlet and the air outlet of the air pump 4 are arranged on the air inlet pipeline 3 and used for sucking air, one end of an air outlet 32 of the air inlet pipeline is downwards arranged at the bottom of the water storage chamber 22 from a higher position of the side wall of the pump chamber (preventing water from flowing back to the air pump), the filtering sponge 23 is arranged in the water storage chamber 22, and at least one part of the filtering sponge 23 is positioned in the water after the water is filled. A non-woven fabric layer and/or an activated carbon layer and/or a melt-blown fabric layer are/is arranged above the filtering sponge, namely, one, two or all of the three layers can be selected and determined according to the application requirements. The activated carbon layer is beneficial to removing peculiar smell, and the melt-blown cloth layer can remove certain germs. An exhaust port 24 is formed at the uppermost portion, and the exhaust port 24 is connected to the intake port 11 of the housing 1 through an exhaust line 5.

The cover body 1 is worn at the mouth of a user, the user can hold the air purification box by hand or fix the air purification box 2 on the body by using fixing parts such as rubber belts, and the cover body is connected with the air purification box 2 through the exhaust pipeline 5. During the use, open the air pump and bleed, it is abundant that gaseous can get rid of PM2.5, multiple harmfulness such as smoke and dust after washing and sponge filter to keep the air moist, purify once more through non-woven fabrics layer, activated carbon layer and melt-blown cloth layer, can get rid of peculiar smell, bacterium etc. is favorable to keeping moist healthy fresh air. The gas is sent into the mask body for breathing of people, and then the exhaled gas is exhausted through the exhaust valve.

A microphone 6 can be arranged in the cover body, a loudspeaker 7 is arranged on the air purification box, and the sound emitted by a person is collected and amplified, so that the voice communication is facilitated, and the situations that the communication is not facilitated, such as small sound caused by sealing, are prevented.
