The cleaning liquid sprayed by the nozzle 31 moves downward under the action of gravity after completing the cleaning work of the 3D printed part, drops onto the liquid collecting plate 13, is collected and pooled under the action of the liquid collecting plate 13, and is transferred to the cleaning liquid recovery bin 12. The cleaning liquid in the cleaning liquid recovery bin 12 enters the cleaning liquid storage tank 33 through a pipeline or a communication port, and is then used again, so as to achieve the purpose of recycling the cleaning liquid. Of course, the cleaning liquid needs to be replaced after a certain period of time.

[0038] Further optimization scheme, the cleaning tank 1 is provided with a mounting port, and the cleaning tank 1 is rotatably connected with a tank cover 14 at the mounting port. The tank cover 14 isolates the cleaning cavity 11 from the outside. The tank cover 14 is rotatably connected with the cleaning tank 1 through a hinge. The tank cover 14 and the cleaning tank 1 form an integral whole, so that the cleaning cavity 11 becomes a space relatively isolated from the outside. When the 3D printed part is cleaned in the cleaning cavity 11, the tank cover 14 prevents the cleaning liquid from splashing out.

[0039] Further optimization scheme, the nozzle 31 is connected with a pressure sensor for detecting the pressure of the cleaning liquid sprayed by the nozzle 31. The pressure sensor is electrically connected with a central processing unit. An opening adjusting piece for controlling the flow of the cleaning liquid is arranged between the cleaning liquid supply and the cleaning pipe 32, and the opening adjusting piece is electrically connected with the central processing unit. The pressure of the cleaning liquid sprayed by the nozzle 31 is detected by the pressure sensor, and the detected pressure data is transmitted to the central processing unit in real time. The central processing unit compares the received pressure data with a safe pressure range of the cleaning liquid. The safe pressure range of the cleaning liquid is between the pressure value required to ensure the cleaning effect of the 3D printed part and the critical pressure value at which the cleaning liquid damages the 3D printed part. When the real-time monitored pressure data of the cleaning liquid is less than the safe pressure range of the cleaning liquid, the flow of the cleaning liquid in the cleaning pipe 32 is increased by adjusting the opening adjusting piece, and the pressure of the cleaning liquid sprayed by the nozzle 31 is increased. When the real-time monitored pressure data of the cleaning liquid is in the safe pressure range of the cleaning liquid, no adjustment is needed. When the real-time monitored pressure data of the cleaning liquid is greater than the safe pressure range of the cleaning liquid, the flow of the cleaning liquid in the cleaning pipe 32 is reduced by adjusting the opening adjusting piece, and the pressure of the cleaning liquid sprayed by the nozzle 31 is reduced. The opening adjusting piece in this embodiment can be an electronic control valve, which can control the opening of the valve through electronic information. This embodiment controls the pressure of the cleaning liquid sprayed by the nozzle by real-time monitoring the pressure of the cleaning liquid sprayed by the nozzle and judging whether the pressure data is within the safe pressure range of the cleaning liquid, to prevent the cleaning liquid from damaging the 3D printed part due to excessive pressure, or the cleaning effect from being poor due to insufficient pressure.

[0040] The embodiment also discloses a control display screen and a power switch, the device operation is controlled through the control display screen, such as whether the water pump 34 works, whether the first driving structure works, and information such as working duration, and the whole cleaning machine is controlled to be powered on or not through the power switch.
