Spray-type washers consume a lot of water, have blind spots when cleaning complex-shaped fruits and vegetables with heavy surface deposits, and offer poor cleaning performance. Brush and drum-type washers are only suitable for cleaning root vegetables and can significantly damage leafy vegetables and tender fruit. Existing fruit and vegetable washers are limited in functionality, unable to clean a wide variety of fruits and vegetables, and ineffective in degrading pesticide residues.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Example 1

[0035] Reference Figure 1-4 An intelligent fruit and vegetable washing device includes a washing machine frame 1, a water supply component, a transmission component and an auxiliary cleaning component. The washing machine frame 1 consists of a washing area 2, a transmission area 5 and a discharge area 9. A liquid level sensor 21 is installed in the washing area 2. A flushing mechanism for washing fruits and vegetables with clean water is fixedly installed on the transmission area 5. A control port 8 is fixedly installed on the side wall of the discharge area 9, and a blanking plate 12 is provided at the end; the flushing mechanism includes a conduit 6, a transverse pipe 35 and a nozzle 36. A pair of conduits 6 are symmetrically fixed at the upper end of the transmission area 5. Several transverse pipes 35 are connected and arranged between the pair of conduits 6. Multiple nozzles 36 are connected and evenly distributed at the lower end of the transverse pipe 35. The conduit 6 is connected to the water supply pipe 24.

[0036] The water supply assembly consists of a water supply pump 26, a water storage tank 31, a water inlet pipe 27, a water injection pipe 22, and a water delivery pipe 24. The water storage tank 31 is fixedly mounted on the outer wall of the washing area 2. The water inlet pipe 27 is connected between the water supply pump 26 and the water storage tank 31. The water delivery pipe 24 is connected between the water supply pump 26 and the flushing mechanism. The water injection pipe 22 is connected between the water delivery pipe 24 and the washing area 2. The first solenoid valve 23 and the second solenoid valve 25 are installed on the water injection pipe 22 and the water delivery pipe 27, respectively.

[0037] The transmission assembly consists of a stirring roller 3, a conveying motor 20 and a transmission belt 32. The stirring roller 3 is rotatably connected between the inner walls of the washing area 2. The conveying motor 20 is fixedly mounted on the side wall of the washing area 2 and the output shaft is coaxially fixedly connected to the stirring roller 3. The transmission belt 32 is transmission-installed in the transmission area 3 and is provided with a baffle on the surface. The conveying motor 20 and the transmission belt 32 are connected by a transmission mechanism; the transmission mechanism includes a pair of transmission wheels 33, a driven gear 11 and a driving gear 34. The pair of transmission wheels 33 are both arranged on the side wall of the washing machine frame 1 and are connected by belt drive. One transmission wheel 33 is fixedly connected to the output shaft of the transmission motor 20, and the other transmission wheel 33 is fixedly connected to the driving gear 34. The driven gear 11 is fixedly connected to the driving roller of the transmission belt 32, and the driving gear 34 is meshed with the driven gear 11.

[0038] The auxiliary cleaning component includes a liquid pump 18, a liquid extraction pipe 17, a liquid infusion pipe 15 and a liquid storage tank 16. The liquid pump 18 and the liquid storage tank 16 are both fixed at the bottom of the washing machine frame 1. The liquid extraction pipe 17 is connected between the liquid pump 18 and the liquid storage tank 16, and the liquid infusion pipe 15 is connected between the liquid pump 18 and the cleaning area 2.

[0039] A drainage area 19 is provided in the washing machine frame 1 below the cleaning area 2 , a drainage outlet is provided at the lower end of the drainage area 19 , and an automatic control valve is installed in the drainage outlet.

[0040] In this embodiment, when the picked fruits and vegetables need to be washed, water, salt, baking soda and other ingredients that are beneficial to washing are first added to the liquid storage tank to form an auxiliary washing liquid, and then the pneumatic water supply pump 16 is pneumatically driven. At this time, the liquid level sensor 21 senses that the liquid level in the washing area 2 is low, the first solenoid valve 23 is opened, and the second solenoid valve 25 is closed. The clean water in the water storage tank 31 is injected into the washing area 2 through the water inlet pipe 27 and the opened first solenoid valve 23 through the water injection pipe 22.

[0041] When the liquid level sensor 21 detects that the water level in the cleaning zone 2 has reached the preset level, the first solenoid valve 23 closes, stopping water injection. The second solenoid valve 23 opens, allowing clean water in the water tank 31 to enter the conduit 6 through the water inlet pipe 27 and be sprayed out from the various nozzles 36. At this point, the fruits and vegetables are immersed in the cleaning zone 2, while the auxiliary cleaning components function. The liquid pump 18 delivers auxiliary cleaning liquid from the liquid storage tank 16 through the liquid extraction pipe 17 and the liquid delivery pipe 15 to the cleaning zone 2, where it mixes with the clean water. The delivery motor 20 is activated, driving the agitator roller 3 to rotate. The rotation and stirring of the agitator roller 3 accelerates the softening of dirt and other impurities on the surface of the fruits and vegetables, while the components in the auxiliary cleaning liquid begin to degrade pesticide residues.

[0042] During this process, the rotation of the stirring roller 3 can not only stir the fruits and vegetables in the cleaning area 2, but also push the soaked fruits and vegetables to the conveyor belt 32 of the conveying area 5, and the clean water sprayed from the nozzle 36 can perform high-pressure washing on the fruits and vegetables to further remove residual dirt and auxiliary cleaning liquid.

[0043] After that, the fruits and vegetables are driven by the conveyor belt 32 to move to the discharge area 9. The baffle on the surface of the conveyor belt 32 ensures that the fruits and vegetables move forward stably during the transmission process and fall from the drop plate 12 to enter the subsequent process. During the whole process, the drainage area 19 collects the sewage generated by cleaning, and the automatic control valve of the drainage outlet opens according to the set program to discharge the sewage.

[0044] It should be noted that the intelligent program control technology of the above-mentioned control port 8, first solenoid valve 23, second solenoid valve 25, water supply pump 26, liquid pump 18, conveying motor 20, automatic control valve and liquid level sensor 21 are all mature existing technologies, and this technology is not the technical improvement of the present invention, so it will not be elaborated here.

[0045] Example 2

[0046] Reference Figure 5 and Figure 6 The difference from the first embodiment is that a drying assembly for air-drying water stains on the surface of fruits and vegetables is installed on one side of the upper end of the discharge area 9. The drying assembly consists of an air cylinder 10, an air jet pipe 29, and a booster valve 30. The air cylinder 10 is fixedly connected to the upper end of the discharge area 9. Several air jet pipes 29 are arranged on the side wall of the air cylinder 10 and are connected to it. The booster valve 30 is installed between the air jet pipe 29 and the air cylinder 10. A gas supply mechanism for supplying gas to the air cylinder 10 is installed on the side wall of the washing machine frame 1.

[0047] The gas delivery mechanism includes a piston cylinder 37, a piston 47, an air inlet pipe 42 and an air delivery pipe 43. The piston cylinder 37 is fixed to the side wall of the washing machine frame 1. The piston 47 is sealingly and slidingly connected between the inner wall of the piston cylinder 37. The air inlet pipe 42 is connected between the outside and the upper end of the piston cylinder 37. The air delivery pipe 43 is connected between the piston cylinder 37 and the air storage cylinder 10. A pushing mechanism for pushing the piston 47 to move vertically back and forth is installed on the side wall of the washing machine frame 1.

[0048] The pushing mechanism includes a slide rail seat 14, a slider 40, a connecting rod 41, a disc 38 and a rotating rod 39. The slide rail seat 14 is fixedly connected to the side wall of the washing machine frame 1 and is located below the piston cylinder 37. The slider 40 is slidably connected to the slide rail seat 14. The connecting rod 41 is fixedly connected between the slider 40 and the piston 47. The disc 38 is coaxially fixedly connected to the driven gear 11. One end of the rotating rod 39 is rotatably connected to the surface of the disc 38, and the other end is rotatably connected to the surface of the slider 40.

[0049] A one-way valve is installed in the air inlet pipe 42 to only allow air to flow from the outside to the piston cylinder 37 , and a one-way valve is installed in the air delivery pipe 43 to only allow air to flow from the piston cylinder 37 to the air storage cylinder 10 .

[0050] In this embodiment, after the fruits and vegetables have completed the soaking and cleaning in the cleaning area 2 and the water rinsing in the conveying area 5, they are conveyed to the discharge area 9 by the conveyor belt 32, and the drying process is officially started.

[0051] When the transmission assembly is in operation, the conveyor motor 20 drives the stirring roller 3 to rotate, while the transmission mechanism simultaneously rotates the conveyor belt 32. In the transmission mechanism, a pair of drive pulleys 33 are driven by belts. One drive pulley 33 is connected to the output shaft of the conveyor motor 20, and the other drive pulley 33 drives the driving gear 34 to rotate. The driving gear 34 meshes with the driven gear 11. As the driven gear 11 rotates, the coaxially fixed disc 38 also rotates.

[0052] As disc 38 rotates, one end of rotating rod 39 moves in a circular motion with disc 38, while the other end is rotatably connected to slider 40, thereby driving slider 40 to slide back and forth linearly on slide rail seat 14. The reciprocating motion of slider 40 is transmitted to piston 47 via connecting rod 41, causing piston 47 to reciprocate vertically within piston cylinder 37.

[0053] When the piston 47 moves upward, the air pressure in the piston cylinder 37 decreases, the one-way valve in the air inlet pipe 42 opens, and outside air enters the piston cylinder 37. When the piston 47 moves downward, the air pressure in the piston cylinder 37 increases, the one-way valve in the air delivery pipe 43 opens, and air is pressed into the air reservoir 10. As the piston 47 continues to reciprocate, the air in the air reservoir 10 gradually accumulates, and the pressure continues to rise.

[0054] When the pressure within the air reservoir 10 reaches the set threshold of the boost valve 30, the boost valve 30 opens, and the high-pressure gas within the air reservoir 10 is ejected at high speed through the air jet tube 29. The powerful airflow acts on the surface of the fruits and vegetables, quickly drying any remaining water stains. Continuously transported by the conveyor belt 32, the fruits and vegetables sequentially pass through the air jet area of ​​the air jet tube 29, completing a comprehensive and efficient air-drying process before exiting the device through the blanking plate 12. Throughout this process, the various components work seamlessly together, utilizing the power generated by the transmission components to drive the air delivery mechanism, achieving energy-saving air-drying of fruits and vegetables without consuming additional energy. This ensures effective cleaning and drying while enhancing the device's energy-saving and environmentally friendly performance.

[0055] Example 3

[0056] Reference Figure 5 and Figure 7 The difference from the first and second embodiments is that a stirring assembly for stirring the auxiliary cleaning liquid is provided above the liquid storage tank 16. The stirring assembly comprises a circular main member 45 and stirring blades 46. A plurality of stirring blades 46 are evenly distributed around the circular main member 45 and are rotatably connected to the circular main member via a resistance shaft. A drive mechanism for driving the stirring assembly to vertically reciprocate and stir is mounted on the slider 40. The drive mechanism includes a bent rod 44, one end of which is fixedly connected to the lower end of the slider 40 and the other end is fixedly connected to the center of the circular main member.

[0057] In this embodiment, during operation of the transmission assembly, the conveying motor 20 drives the stirring roller 3 to rotate, while simultaneously rotating the conveyor belt 32 through the transmission mechanism. Furthermore, the disc 38, rotating rod 39, and other components of the transmission mechanism work together to drive the slider 40 to slide back and forth linearly on the slide rail seat 14. As the slider 40 slides, the bent rod 44, fixedly connected to its lower end, moves accordingly. Because the other end of the bent rod 44 is fixedly connected to the center of the circular main component 45 of the stirring assembly, the reciprocating motion of the slider 40 is converted into vertical reciprocating motion of the circular main component 45 through the bent rod 44.

[0058] As the circular main member 45 moves vertically up and down, stirring blades 46 evenly distributed around its circumference also move up and down in the auxiliary cleaning liquid within the liquid storage tank 16. The stirring blades 46 are rotatably connected to the circular main member 45 via a resistance shaft. During their up and down movement, the stirring blades 46, due to the liquid resistance and their own structural characteristics, produce a certain degree of rotation and agitation, thereby fully stirring the auxiliary cleaning liquid (a mixture of salt, baking soda, and water) within the liquid storage tank 16.

[0059] During the stirring process, the salt and baking soda dissolve more evenly in the water, forming a mixed solution of uniform concentration, effectively enhancing the auxiliary cleaning liquid's ability to clean and degrade pesticide residues. The evenly stirred auxiliary cleaning liquid is then pumped by liquid pump 18 through liquid extraction tube 17 and liquid infusion tube 15 to cleaning zone 2, where it mixes with the clean water. In cleaning zone 2, the auxiliary cleaning liquid, combined with the rotation of agitating roller 3, more efficiently softens dirt on the surfaces of fruits and vegetables and decomposes pesticide residues, further enhancing the cleaning effect compared to Examples 1 and 2.
