As shown in fig. 11, the spiral rotating plate 340 includes a hard frame 341 and a soft contact layer 342; the hard frame 341 is a frame portion of the spiral rotating plate 340, the hard frame 341 is integrally distributed along a spiral shape, the soft contact layer 342 is in a spiral structure, and the soft contact layer 342 is sealed and fixed on the hard frame 341 along a spiral track; the inner ring end point of the hard frame 341 is fixed on the pull rod 331, and the outer ring end point of the hard frame 341 is slidingly connected on the inner wall of the shell 310; the soft contact layer 342 is made of food-grade silica gel; two ends of the soft frame 351 are fixed on the soft contact layer 342 between two adjacent circles on the spiral rotating plate 340; after fruit gets into clean bag 353 in, wipe subassembly 350 wholly can take place deformation and vibration under the striking of fruit, and then drive soft contact layer 342 and take place the vibration, make the washing liquid in the casing 310 appear flowing under this kind of vibration, and then carry out vibration cleaning to the dirty on the fruit, after fruit and soft contact layer 342 contact, soft contact layer 342 can appear deformation under the gravity of fruit simultaneously for the area of contact of fruit and soft contact layer 342 grow, soft contact layer 342 and wipe subassembly 350 under the vibration state can be better with the intractable dirty on the fruit wipe down simultaneously.
Preferably, the soft contact layer 342 has a higher modulus of elasticity than the wiping bag 353.
The technical scheme provided by the embodiment of the application at least has the following technical effects or advantages:
1. the vibrating design of the soft contact layer 342 causes the cleaning fluid to flow within the housing 310, thereby vibrating the fruit. The vibration cleaning can remove the stubborn dirt on the surface of the fruit more effectively;
2. the deformation of the soft contact layer 342 under the action of the gravity of the fruit increases the contact area with the fruit, and meanwhile, the vibration state of the soft contact layer is also beneficial to wiping off the stubborn dirt on the fruit, so that the wiping efficiency is remarkably improved;
3. The design of the spiral rotating plate 340 enables the soft contact layer 342 to move along with the rotation of the spiral rotating plate 340, so that fruits with different sizes and shapes are adapted, and the universality and the adaptability of the equipment are improved;
4. The soft contact layer 342 is made of food-grade silica gel, which is safe and harmless, has good elasticity and wear resistance, and can reduce the abrasion of the equipment in the cleaning and wiping processes, so that the service life of the equipment is prolonged, and the damage to fruits is smaller.
