The invention discloses a negative-pressure cleaning and disinfecting
machine with a storage box. The
machine comprises a storage box
assembly, a liquid inlet device, a liquid inlet control valve, a second
pipe connector and a
discharge control valve, a second box connector is formed in the storage box
assembly, the liquid inlet device, the liquid inlet control valve and the second
pipe connectorare in pipeline connection in sequence, and the
discharge control valve is in pipeline connection with the second
pipe connector and is in parallel connection with the liquid inlet control valve. A movably connected valve element
assembly is arranged in the second box connector; and when the valve element assembly is in a normally-
closed state, the second box connector can be sealed, during use, an
endoscope is placed in the storage box assembly, the second pipe connector and the second box connector are in sealed
butt joint, and the valve element assembly is switched to be in an open state. In this way, a
disinfectant can enter the storage box assembly from the liquid inlet device through the second box connector to disinfect the
endoscope, after disinfection is completed, the
disinfectant is discharged through the
discharge control valve, then the storage box assembly is taken out, the valve element assembly is switched to be in the normally-
closed state again, and therefore the storage box assembly is sealed.
