The mounting seat comprises a mounting seat housing and a support portion connected to the mounting seat housing. A fluid channel is formed in the mounting seat housing, the support portion is disposed in the fluid channel, and the fluid channel is capable of fluidly communicating an interior space of a component to be depressurized with the external environment. The breathable film covers on the fluid channel. The drying component is disposed on the support portion and is located between the support portion and the breathable film, and the drying component is configured to absorb moisture entering the fluid channel. In the present disclosure, the drying component is provided inside of the breathable film of the pressure balancing device, and water vapor entering the pressure balancing device is absorbed by the drying component.
