Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] See Figures 1-11 This sterilization and cleaning module includes an electrical control device A and a cleaning device B. The electrical control device A includes an electrical control housing 8, an electrical control board 4, a drive assembly, and a conductive component 5 disposed on the electrical control housing 8. The electrical control board 4 is electrically connected to the drive assembly and the conductive component 5. The cleaning device B includes a rotating cylinder 6, a conductive mating component, and a sterilization generator disposed on the rotating cylinder 6. Brushes 33 are evenly distributed around the rotating cylinder 6 and are driven and connected to the drive assembly. The conductive mating component and the sterilization generator are electrically connected to each other. The conductive component 5 is always electrically connected to the conductive mating component when the rotating cylinder 6 rotates.

[0032] In this embodiment, the cleaning device B is placed in water, and the drive assembly drives the rotating drum 6 to rotate on the electrical control housing 8 under the control of the electrical control board 4. When the rotating drum 6 rotates, the evenly distributed brushes 33 on its periphery clean the surface of fruits, vegetables, and other foods. In addition, since the conductive component 5 is always electrically connected to the conductive mating component when the rotating drum 6 rotates, and the conductive mating component on the rotating drum 6 is also electrically connected to the sterilization generator, the electrical control board 4 can achieve electrical connection with the conductive component 5, the conductive mating component, and the sterilization generator. This allows the sterilization generator to generate electrolysis, ultrasound, ozone, or ultraviolet light for sterilization after being energized, thereby killing pesticides, bacteria, active viruses, and other harmful substances remaining on the surface of fruits, vegetables, and other foods and in the water. This effectively sterilizes and cleans fruits, vegetables, and other foods, thereby improving the cleaning effect of fruits, vegetables, and other foods and making it highly practical.

[0033] The sterilization generator is located on the outside of the rotating cylinder 6 and can be an electrolysis generator, an ultrasonic generator, an ozone generator, or an ultraviolet generator.

[0034] In this embodiment, the sterilization generator can be an electrolysis generator that generates electrolysis during operation; or it can be an ultrasonic generator that generates ultrasonic waves during operation; or it can be an ozone generator that generates ozone during operation; or it can be an ultraviolet generator that generates ultraviolet light during operation. Electrolysis, ultrasonic waves, ozone, or ultraviolet light can all kill harmful substances such as pesticides, bacteria, and active viruses remaining on the surface of fruits, vegetables, and other foods, as well as in water.

[0035] A conductive wire 7 is installed inside the rotating cylinder 6. The conductive mating parts and the sterilization generator are electrically connected through the conductive wire 7. That is, the conductive wire 7 is hidden inside the rotating cylinder 6, and the conductive mating parts and the sterilization generator are electrically connected through the hidden conductive wire 7.

[0036] The conductive component 5 or the conductive mating component is in the shape of a ring. The rotating cylinder 6 rotates on the electronic control housing 8 under the drive of the drive assembly, and the conductive mating component rotates with the rotating cylinder 6.

[0037] In this embodiment, the conductive mating component rotates together with the rotating cylinder 6, and the conductive component 5 or the conductive mating component is arranged in a circular shape, so the conductive mating component will always be electrically connected to the conductive component 5 when rotating.

[0038] The top of the control housing 8 is open and is fixedly connected to the control cover plate 9. The control housing 8 and the control cover plate 9 form a control cavity 10. The control board 4, the drive assembly, and the conductive component 5 are respectively disposed in the control cavity 10. The bottom of the control housing 8 is provided with a conductive hole 11. The conductive component 5 is provided with a conductive spring pin. The conductive spring pin extends out of the control cavity 10 through the conductive hole 11.

[0039] In this embodiment, the electronic control board 4, the drive assembly, and the conductive component 5 can be fixed to the electronic control housing 8 through the top opening of the electronic control housing 8. The electronic control cover plate 9 is fixed to the top opening of the electronic control housing 8 by fasteners and covers the electronic control board 4, the drive assembly, and the conductive component 5. In addition, the conductive hole 11 is provided at the bottom of the electronic control housing 8 so that the conductive spring pin on the conductive component 5 can extend out of the electronic control cavity 10 through the conductive hole 11.

[0040] The conductive spring pins include a negative conductive spring pin 12 and a positive conductive spring pin 13. The negative conductive spring pin 12 and the positive conductive spring pin 13 extend out of the control cavity 10 through the conductive holes 11 toward the bottom of the control housing 8. The conductive mating parts include a negative conductive mating piece 14 and a positive conductive mating piece 15. The negative conductive mating piece 14 and the positive conductive mating piece 15 are annular conductive pieces and are fixed to the top of the rotating cylinder 6.

[0041] In this embodiment, the elastic conductivity of the negative conductive spring pin 12 and the positive conductive spring pin 13 is utilized to ensure that the annular negative conductive mating piece 14 and the positive conductive mating piece 15 are always in elastic conductive contact with the negative conductive mating piece 14 and the positive conductive mating piece 15 respectively as the rotating cylinder 6 rotates, thereby ensuring effective electrical connection between the negative conductive spring pin 12 and the negative conductive mating piece 14, and between the positive conductive spring pin 13 and the positive conductive mating piece 15.

[0042] The top of the rotating cylinder 6 is open and sealed with a top cover 19. A sealed cavity 20 is formed between the rotating cylinder 6 and the top cover 19. A conductive wire 7 is provided in the sealed cavity 20. The conductive wire 7 is electrically connected to the conductive mating part and the sterilization generator respectively.

[0043] Specifically, the sterilization generator is an electrolysis generator and includes a negative electrolysis plate 16 and a positive electrolysis plate 17. The negative electrolysis plate 16 and the positive electrolysis plate 17 are respectively fixed at the bottom of the rotating cylinder 6. The negative conductive mating plate 14 and the positive conductive mating plate 15 are electrically connected to the negative electrolysis plate 16 and the positive electrolysis plate 17 respectively through conductive wires 7.

[0044] That is, the negative conductive spring pin 12, the negative conductive mating piece 14, and the negative electrolytic piece 16 are electrically connected to each other, and the positive conductive spring pin 13, the positive conductive mating piece 15, and the positive electrolytic piece 17 are electrically connected to each other. This allows the control board 4 to electrically connect the negative electrolytic piece 16 and the positive electrolytic piece 17, enabling the negative electrolytic piece 16 and the positive electrolytic piece 17 to obtain working power. At the same time, the control board 4 can also control the negative electrolytic piece 16 and the positive electrolytic piece 17 to perform electrolysis of water to generate a large number of H+ ions and OH- ions, thereby decomposing and killing harmful substances such as pesticides, bacteria, and active viruses remaining on the surface of fruits, vegetables, and other foods and in the water.

[0045] In this embodiment, a sealing element 18 is provided at the top opening of the rotating cylinder 6, and the top cover 19 is sealed and connected through the sealing element 18. The rotating cylinder 6 and the top cover 19 are sealed together through the sealing element 18 to prevent the conductive wire 7 located in the sealed cavity 20 from being damaged by moisture.

[0046] In this embodiment, the conductive component 5 is a low-voltage component with a working voltage of 3V-24V. Therefore, the negative conductive spring pin 12 and the negative conductive mating piece 14, and the positive conductive spring pin 13 and the positive conductive mating piece 15 are connected by low voltage, which is safe to use.

[0047] The top of the top cover 19 is provided with two annular positioning grooves 21, one inside and one outside. Positioning holes 22 are provided on the annular positioning grooves 21. Connecting feet 23 are respectively positioned on the negative conductive mating piece 14 and the positive conductive mating piece 15. The negative conductive mating piece 14 and the positive conductive mating piece 15 are respectively set on the annular positioning grooves 21. The connecting feet 23 extend into the sealing cavity 20 through the positioning holes 22 and are electrically connected to one end of the conductive wire 7.

[0048] In this embodiment, the negative conductive mating piece 14 and the positive conductive mating piece 15 are arranged inside and outside, and they are respectively positioned on the positioning hole 22 through the connecting foot 23, thereby being positioned on the inner and outer annular positioning grooves 21 respectively. The connecting foot 23 also extends into the sealing cavity 20 through the positioning hole 22, and one end of the conductive wire 7 is electrically connected to the connecting foot 23.

[0049] To prevent cleaning water from entering the sealing cavity 20 through the positioning hole 22, a sealing sleeve can also be fitted on the connecting leg 23, and the sealing sleeve seals the positioning hole 22.

[0050] The negative electrode electrolytic plate 16 and the positive electrode electrolytic plate 17 are respectively provided with conductive fixing members 24, and are respectively fixed to the bottom of the rotating cylinder 6 by the conductive fixing members 24. The conductive fixing members 24 pass through the rotating cylinder 6, extend into the sealed cavity 20, and are electrically connected to the other end of the conductive wire 7.

[0051] In this embodiment, fixing holes are provided at the bottom of the rotating cylinder 6, on the negative electrode electrolytic plate 16 and the positive electrode electrolytic plate 17. The conductive fixing member 24 can act on the fixing holes to achieve mutual fixing between the negative electrode electrolytic plate 16, the positive electrode electrolytic plate 17 and the rotating cylinder 6. At the same time, the conductive fixing member 24 can also pass through the fixing hole of the rotating cylinder 6 and extend into the sealing cavity 20, and be electrically connected to the other end of the conductive wire 7.

[0052] The above-mentioned sterilization and cleaning module can be applied to a fruit and vegetable cleaning machine. The fruit and vegetable cleaning machine includes a body 1, the top of the body 1 is open and a cover 2 is openable and closable, the cover 2 is provided with a cover assembly cavity 3, the electronic control device A is installed and disassembled on the cover assembly cavity 3, and the cleaning device B is installed and disassembled on the body 1.

[0053] The drive assembly includes a drive motor and a reducer 25 connected to the drive motor. A drive shaft 26 is provided on the top cover 19. A housing opening 27 is provided at the bottom of the electrical control housing 8. The drive shaft 26 extends into the electrical control cavity 10 through the housing opening 27 and is connected to the reducer 25. A positioning shaft 28 is provided at the bottom of the machine body 1. A groove 29 is provided at the bottom of the rotating cylinder 6. An elastic element 30 is provided in the groove 29. The positioning shaft 28 is elastically rotated with the groove 29 through the elastic element 30.

[0054] In this embodiment, the drive shaft 26 is integrally set with the top cover 19. When the drive motor is working, it rotates through the reduction gear set in the reducer 25. When the reduction gear set rotates, it drives the top cover 19 and the rotating cylinder 6 to rotate through the drive shaft 26. Thus, when the rotating cylinder 6 rotates, it uses the evenly distributed brushes 33 on the periphery to wash the food such as fruits, vegetables and vegetables placed in the machine body 1.

[0055] Meanwhile, an elastic element positioning sleeve 31 and a positioning shaft connecting sleeve 32 are provided in the groove 29. The elastic element 30 is positioned on the elastic element positioning sleeve 31, and its two ends elastically act on the top wall of the groove 29 and the bottom wall of the elastic element positioning sleeve 31, respectively. The positioning shaft connecting sleeve 32 abuts against the elastic element positioning sleeve 31, and the positioning shaft 28 passes through the positioning shaft connecting sleeve 32 and the elastic element 30 in sequence. This not only enables the bottom surface of the cleaning device B to achieve stable rotation through the positioning action of the positioning shaft 28, but also allows it to move elastically in the direction of the electronic control device A during rotation. This ensures that the negative conductive spring pin 12 and the positive conductive spring pin 13 are always in elastic conductive contact with the negative conductive mating piece 14 and the positive conductive mating piece 15, respectively, when the rotating cylinder 6 rotates.
