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. The produced effect is that the contact area and the pressure of the first binding surface or/and the second binding surface and the face can be adjusted, and the comfort level can be flexibly adjusted.
The seal structure 102 may include three or more seal members, such as a first seal member 201, a second seal member 205, and a third seal member (not shown).
The fluid device 204 may be an air pump that controllably moves fluid air into or out of the enclosed space; the change in volume of the enclosed space causes mechanical deformation of the sealing structure, and the mechanical deformation of the sealing structure 102 causes a change in the elastic force of the sealing structure 102 against the user's face.

In the embodiment, the sealing ring is the most common sealing device, is simple to manufacture and has a good sealing effect. The fluid flowing into or out of the sealed space of the first and second sealing members 201 and 205 causes the volume of the sealed space to change, the change in the volume of the sealed space causes the mechanical deformation of the sealing structure 102, and the mechanical deformation of the sealing structure 102 causes the elastic force of the sealing structure 102 acting on the face of the user to change.
The elastic force change here includes a change in the magnitude of the elastic force and a change in the position where the elastic force acts. The change of elasticity size and the change of elasticity effect position can improve and wear the travelling comfort when guaranteeing the result of use of respiratory protection device seal in order to guarantee the gauze mask.
