As shown in fig. 1 and fig. 2, the active adjustment inspection and quarantine respiratory protection device (such as a mask, a gas mask, etc.) includes a respiratory protection device body 101, a sealing structure 102 and a fixing mechanism 103. Wherein:

the sealing structure 102 is connected with the breathing protective device body 101, and the sealing structure 102 is abutted against the face of a user (namely covering the mouth-nose part) when in use. The respiratory protection device body 101 includes a shell that conforms to the shape of the user's face.

The fixing mechanism 103 is connected with the sealing structure 102. In the use state, the fixing mechanism 103 used in cooperation acts on the sealing structure 102, so that the sealing structure 102 generates mechanical deformation and is elastically attached to the face of a user, and air leakage around the sealing structure 102 is avoided.

The first sealing part 201 and the second sealing part 205 are respectively provided with a sealing part shell and a closed space, the sealing part shell surrounds the closed space, the inside of the closed space is communicated with a fluid device 204 through a fluid pipeline 203, the fluid device 204 controllably causes fluid to flow into or out of the closed space, and the controllable fluid flow into or out of the closed space causes the volume of the closed space to change.

The sealing structure 102 includes a first sealing member 201 and a second sealing member 205. Each of the first seal member 201 and the second seal member 205 has a seal member case and a sealed space, and the seal member case encloses the sealed space in a fluid-tight manner. When the sealing device is used, the sealing device shells of the first sealing device 201 and the second sealing device 205 are attached to the face of a user to form a first attaching surface and a second attaching surface respectively. The inside of the closed space is communicated with a fluid device 203 through a fluid pipeline 202, the fluid device 203 controllably causes fluid to flow into or out of the closed space, the controllable flow of the fluid into or out of the closed space causes pressure change of the fluid in the closed space, and the pressure change causes interference change of the sealing structure 102 and the face of the user.
