[0049] In summary, by arranging the ventilation assembly 100 and the gas conveying assembly 200, when mechanical ventilation is needed, the axial flow fan 102a can be controlled to work to guide the gas in the gas conveying pipe 201 outwards, with the flow of the gas, the gas conveying pipe 201 tends to be in a negative pressure state, the sealing ball 201a-3 moves downwards, so that the external air enters the gas conveying pipe 201 through the gas conveying groove 201a-1a, ensuring the stability and safety of gas conveying, and more meeting the actual use requirements.
