[0034] Furthermore, a nozzle 150 is provided inside the inner shell 110, and the nozzle 150 is also connected to an external water pipe. The nozzle 150 is positioned higher than the bottom of the cleaning cylinder 200, and the nozzle 150 sprays water toward the cleaning cylinder 200, thereby rinsing the cleaning cylinder 200 and / or the oysters inside the cleaning cylinder 200.

During the oyster cleaning process, the external water pipe or the return water pipe can be turned on as needed.

[0042] The working principle of the oyster cleaning device provided in this embodiment is as follows:

[0043] Place the oysters and cleaning brush 300 into the cleaning cylinder 200 through opening 212. Connect the cover 220 to the cylinder 210 to prevent the oysters and cleaning brush 300 from falling out of opening 121 during the inversion process. Install the cleaning cylinder 200 into the inner shell 110. At this time, under the compression of the elastic element 146, the rotating shaft 142 remains engaged with the output shaft of the cleaning cylinder 200 or the drive motor 144, and the connecting shaft 143 remains engaged with the cleaning cylinder 200.

[0044] The nozzle 150 is activated to spray water into the oysters in the cleaning cylinder 200. When the water level is higher than the bottom of the cleaning cylinder 200, the magnetic generator 130 is activated, and the motor 132 drives the magnetic component 134 to rotate, generating a rotating magnetic field. This, in turn, causes the cleaning brush 300 to rotate, colliding and rubbing against the oyster shells to clean the dirt on the shells. Every so often, the drive motor 144 is activated to control the cleaning cylinder 200 to rotate, causing the oysters inside to turn over and preventing uneven cleaning. Before cleaning the oysters, the nozzle 150 sprays external water into the inner shell 110. After reaching the predetermined water level to begin cleaning, the outlet can be opened and the water pump 440 can be activated to pump the wastewater in the inner shell 110 into the water tank 420 for filtration. The filtered liquid is then sprayed onto the oysters to improve the cleaning effect, or the filtrate can be directly discharged, and water from the external water pipe can be sprayed onto the oysters.

[0045] After cleaning the oysters, turn off the magnetic generator 130, open the water outlet to drain the wastewater from the inner shell 110, and activate the nozzle 150 to spray water from an external water source or filtered water from the water tank 420 to rinse the cleaning cylinder 200 and the oysters, washing away any residual mud and sand. Finally, disassemble the cleaning cylinder 200 and the inner shell 110, and collect the cleaned oysters.

The lifting motor 162 is located at the upper end of the main body 100, and a threaded rod 164 is fixedly connected to the lower end of the lifting motor 162. The outer side of the threaded rod 164 is helically connected to the telescopic rod 148, and the end of the telescopic rod 148 away from the threaded rod 164 can be engaged with the connecting shaft 143. When the cleaning cylinder 200 and the inner shell 110 are disassembled, the telescopic rod 148 extends and engages with the connecting shaft 143. Then, the lifting motor 162 drives the cleaning cylinder 200 to rise, facilitating the collection of cleaned oysters.
