[0001] The present invention relates to the technical field of fruit and vegetable cleaning, in particular to a fruit and vegetable cleaning device with a water circulation function. Background Art

[0002] Fruits and vegetables are an essential part of the human diet. Rich in vitamins, minerals, and fiber, they offer numerous health benefits, including improved digestion, enhanced immunity, and disease prevention. Their diverse colors, shapes, and textures add rich diversity to the diet. Washing fruits and vegetables is an important step in ensuring food safety and health.

[0003] Existing fruit and vegetable washing devices usually use weakly alkaline clean water with hydroxyl ions added to directly rinse the fruits and vegetables placed inside the net frame, and then the wastewater generated by the washing is directly discharged. As a result, a large amount of washing water is required when washing fruits and vegetables, resulting in a waste of washing water and increasing the cost of washing water. To this end, we propose a fruit and vegetable washing device with a water circulation function. Summary of the Invention

[0034] In some embodiments, a small amount of a chemical reagent containing hydroxyl ions is added to the hydroxyl ion cleaning water, making the cleaning water slightly alkaline. Hydroxyl ions are hydroxide ions with a negative charge, which can significantly improve the cleaning effect on fruits and vegetables because their alkalinity helps to emulsify the dirt on the surface of fruits and vegetables and neutralize acidic pollutants, enhance the performance of the cleaning water, and help neutralize acidic substances on the surface of fruits and vegetables, thereby improving the cleaning effect and ensuring that fruits and vegetables are cleaner and safer.

[0035] In addition, the electrical components and electrical equipment mentioned above all use external power supplies. The circuits, electronic components, and modules involved in the present invention are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to the internal structure and methods.

[0036] Working principle: By setting a filter box 120 and a filter box 2 140 on the side wall of the casing 100, the fruits and vegetables inside the rotating drum 110 can be rinsed with hydroxyl ion cleaning water in the water spray part 161. The waste water is sent to the inside of the filter box 120 through the water pump 130 and the water supply pipe 131, and is filtered by the coarse filter 124. It is then filtered again by the dense filter 145 of the filter box 2 140. The flushing water then flows to the clean water tank 150 and is pressurized by the booster pump 171 and sent back to the inside of the water spray part 161 for washing fruits and vegetables again, thereby realizing the recycling of the flushing water. The cleanliness of the flushing water after filtration is improved by the double filtration of the filter box 120 and the filter box 2 140 , thereby saving the use of rinsing water when rinsing fruits and vegetables and reducing the cost of using rinsing water; after using the filter box 120 and the filter box 2 140, the bolts of the fastening block 123 can be loosened to pull the drawer 122 outward, and the dirt on the top of the coarse filter screen 124 inside the drawer 122 can be cleaned, and then the locking knob 142 can be loosened to open the cleaning door 141, and then the telescopic rod 143 can be controlled to extend so that the dirt on the dense filter screen 145 is pushed outward from the sewage door by the pushing plate 144, thereby realizing convenient cleaning of the inside of the filter box 120 and the filter box 2 140, solving the common problem of inconvenient cleaning of the dirt inside the filter box and saving manpower.
