The working principle of the drawer is described as follows:
manual mode:
the motor and the electromagnetic push rod are not electrified, the push rod of the electromagnetic push rod extends out to overcome the elastic force of the spring and abut against the first fork part 73a to press the second fork part downwards, and the second fork part is connected with the second driving piece in a sliding mode. The drawer body is pulled outwards manually, the sliding block connected to the drawer body slides forwards along the sliding rail and drives the connecting shaft in driving connection with the drawer body to move forwards, the connecting shaft is in driving connection with the gear, and the gear rotates relative to the rack, so that the connecting shaft and the first bevel gear are driven to rotate synchronously, the first bevel gear drives the second bevel gear to rotate and drives the screw to rotate, the screw drives the driving block in threaded connection with the screw to move upwards, and therefore the basket is lifted. When the drawer is fully pulled out, the basket is raised to the set uppermost position.
When the connecting shaft rotates, the second fork part of the shifting fork is connected with the gear in a sliding mode, so that the second driving piece cannot be driven to rotate, and only the second fork part slides along the tooth circumference of the second driving piece.
When the drawer body is pushed back, the components act reversely, the basket descends, and the drawer body retracts into the cabinet body.
Automatic mode:
the button on the control panel of the disinfection cabinet is pressed, the disinfection cabinet control system supplies power to the electromagnetic push rod, the push rod retracts after the electromagnetic push rod is powered on, the shifting fork rotates under the elastic force of the elastic piece at the moment, and the elastic piece presses down the second fork part to enable the second fork part to abut against the teeth of the second driving piece; the motor is electrified to work, the motor output shaft drives the second driving piece to rotate, the second driving piece drives the shifting fork to synchronously rotate, so that the first driving piece is driven to rotate, the first driving piece drives the connecting shaft to rotate, the connecting shaft drives the gear coaxially connected with the connecting shaft and the first bevel gear to synchronously rotate, when the gear moves forwards along the rack to drive the drawer body to open, the first bevel gear drives the second bevel gear, the second bevel gear drives the screw rod, the screw rod drives the driving block, the driving block drives the basket to ascend, and when the drawer body is completely opened, the basket ascends to the highest design position.
After the drawer body is completely opened, the motor is powered off, and the electromagnetic push rod is powered off; the push rod of the electromagnetic push rod extends out to abut against the first fork part, and overcomes the elasticity of the elastic part to enable the shifting fork to rotate and reset. After the articles are taken and placed, the drawer body is pushed back manually. The action principle of each component is the same as that of the manual mode.
