Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, specifically a fruit and vegetable cleaning machine. Background Technology

[0002] Chinese patent application CN201410536647.6 discloses a fruit and vegetable cleaning bucket. When in use, clean water is filled into the cleaning bucket, the fruit to be cleaned is placed into the cleaning bucket, the bucket lid is fastened, and the rotating cleaning device is agitated. The cleaning roller can continuously agitate the fruit to be cleaned, and the bristles on the top can clean the stains and pesticide residues on the surface of the fruit. However, the entire cleaning process requires the user to manually stir with the handle, which is inefficient and time-consuming.

[0003] To address this, relevant technical personnel have conducted research and development, such as the invention application disclosed in Chinese Patent No. CN201810629816.9, which discloses a fruit cleaning device with a cleaning brush roller. Although it can use a motor to drive the transmission shaft to drive the cleaning brush roller to clean the fruit, it can only use the cleaning brush roller to perform simple washing of the fruit and cannot remove harmful substances from the fruit or the washing water, resulting in poor fruit cleaning effect.

[0004] Therefore, further improvements are necessary. Utility Model Content

Brushes are evenly distributed around the periphery of the rotating cylinder and are driven and connected to the drive assembly. The rotating cylinder rotates within the body of the machine body under the drive of the drive assembly. The electrolytic conductive mating component and the electrolytic component are respectively installed on the rotating cylinder and are electrically connected to each other. The electrolytic conductive component is always electrically connected to the electrolytic conductive mating component when the rotating cylinder rotates.

[0007] The electrolytic conductive component or the electrolytic conductive mating component is circular, and the electrolytic conductive mating component rotates with the rotating cylinder.

[0008] The rotating cylinder is provided with a conductive wire, and the electrolytic conductive fitting is electrically connected to the electrolytic component through the conductive wire.

[0009] The electronic control device further includes an electronic control housing and an electronic control cover plate fixed to the top opening of the electronic control housing.

An electrolytic conductive hole is provided at the bottom of the electronic control housing. A conductive spring pin is provided on the electrolytic conductive element. The conductive spring pin extends out of the electronic control cavity through the electrolytic conductive hole.

[0010] The conductive spring pin includes a negative conductive spring pin and a positive conductive spring pin (13). The negative conductive spring pin and the positive conductive spring pin extend out of the electrical control cavity through the electrolytic conductive hole toward the bottom of the electrical control housing. The electrolytic conductive mating part includes a negative electrolytic conductive mating piece and a positive electrolytic conductive mating piece. The negative electrolytic conductive mating piece and the positive electrolytic conductive mating piece are annular conductive pieces and are respectively fixed to the top of the rotating cylinder. The negative conductive spring pin and the positive conductive spring pin are always in elastic conductive contact with the negative electrolytic conductive mating piece and the positive electrolytic conductive mating piece respectively when the rotating cylinder rotates.

[0011] The electrolytic element includes a negative electrolytic plate and a positive electrolytic plate, which are respectively fixed to the bottom of the rotating cylinder. The negative electrolytic conductive mating plate and the positive electrolytic conductive mating plate are electrically connected to the negative electrolytic plate and the positive electrolytic plate respectively through conductive wires.

[0012] A sealing element is provided at the top opening of the rotating cylinder, and a top cover is sealed and connected through the sealing element. A sealed cavity is formed between the rotating cylinder and the top cover, and the conductive wire is located inside the sealed cavity.

[0013] The top cover has two annular positioning grooves, one inside and one outside, with positioning holes in each groove. Connecting feet are positioned on the negative electrolytic conductive mating piece and the positive electrolytic conductive mating piece, respectively. The negative electrolytic conductive mating piece and the positive electrolytic conductive mating piece are respectively disposed on the annular positioning grooves. The connecting feet extend into the sealed cavity through the positioning holes and are electrically connected to the conductive wire.

[0016] Through the structural improvements described above, this invention allows the drive assembly to rotate the rotating drum within the machine body under the control of the electronic control board. During rotation, the drum uses evenly distributed brushes to wash the fruits and vegetables placed inside. Furthermore, since the electrolytic conductive component remains electrically connected to the electrolytic conductive mating component during the drum's rotation, and the electrolytic conductive mating component and electrolytic component on the rotating drum are also electrically connected to each other, the electronic control board can achieve electrical connection with the electrolytic conductive component, electrolytic conductive mating component, and electrolytic component.

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.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] See Figures 1-9 This fruit and vegetable washing machine includes a body 1 and a cover 2 that opens and closes at the top of the body 1. The cover 2 has a cover assembly cavity 3, and an electrical control device A is installed in the cover assembly cavity 3. The electrical control device A includes an electrical control board 4, a drive assembly, and an electrolytic conductive component 5. The electrical control board 4 is electrically connected to the drive assembly and the electrolytic conductive component 5. A washing device B is driven and connected to the drive assembly. The washing device B includes a rotating cylinder 6, an electrolytic conductive mating component, and an electrolytic component. Brushes 33 are evenly distributed around the rotating cylinder 6 and are driven and connected to the drive assembly. The rotating cylinder 6 rotates inside the body 1 driven by the drive assembly. The electrolytic conductive mating component and the electrolytic component are respectively installed on the rotating cylinder 6 and are electrically connected to each other. The electrolytic conductive component 5 is always electrically connected to the electrolytic conductive mating component when the rotating cylinder 6 rotates.

[0029] In this embodiment, the drive assembly, controlled by the electronic control board 4, drives the rotating drum 6 to rotate within the machine body 1. During rotation, the rotating drum 6 uses evenly distributed brushes 33 to wash the fruits and vegetables placed inside the machine body 1. Furthermore, since the electrolytic conductive component 5 is always electrically connected to the electrolytic conductive mating component during the rotation of the rotating drum 6, and the electrolytic conductive mating component and electrolytic component on the rotating drum 6 are also electrically connected to each other, the electronic control board 4 can achieve electrical connection with the electrolytic conductive component 5, the electrolytic conductive mating component, and the electrolytic component. This allows the electrolytic component to electrolyze the washing water inside the machine body 1 after being energized, generating a large number of H+ and OH- ions. This decomposes and eliminates harmful substances such as pesticides, bacteria, and viruses remaining in the fruits, vegetables, and washing water, effectively improving the washing effect and demonstrating strong practicality.

[0030] The electrolytic conductive component 5 or the electrolytic conductive mating component is in the shape of a ring, and the electrolytic conductive mating component rotates with the rotating cylinder 6.

[0031] In this embodiment, the electrolytic conductive mating component rotates together with the rotating cylinder 6, and the electrolytic conductive component 5 or the electrolytic conductive mating component is arranged in a circular shape. The electrolytic conductive mating component will always be electrically connected to the electrolytic conductive component 5 when rotating.

[0032] A conductive wire 7 is installed inside the rotating cylinder 6, and the electrolytic conductive mating parts and the electrolytic parts are electrically connected through the conductive wire 7.

[0033] The conductive wire 7 is hidden inside the rotating cylinder 6, and the electrolytic conductive mating parts and the electrolytic parts are electrically connected through the hidden conductive wire 7.

[0034] The electronic control device A also includes an electronic control housing 8 and an electronic control cover plate 9 fixed to the top opening of the electronic control housing 8. An electronic control cavity 10 is formed between the electronic control housing 8 and the electronic control cover plate 9. The electronic control board 4, the drive assembly, and the electrolytic conductive element 5 are respectively disposed in the electronic control cavity 10. An electrolytic conductive hole 11 is provided at the bottom of the electronic control housing 8. A conductive spring pin is provided on the electrolytic conductive element 5. The conductive spring pin extends out of the electronic control cavity 10 through the electrolytic conductive hole 11.

[0035] In this embodiment, the electronic control board 4, the drive assembly, and the electrolytic conductive element 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 electrolytic conductive element 5. In addition, the electrolytic conductive hole 11 is provided at the bottom of the electronic control housing 8 so that the conductive spring pin on the electrolytic conductive element 5 can extend out of the electronic control cavity 10 through the electrolytic conductive hole 11.

[0036] In this embodiment, the electronic control device A can be installed and removed from the cover assembly cavity 3.

[0037] 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 at the bottom of the control housing 8 through the electrolytic conductive hole 11. The electrolytic conductive mating parts include a negative electrolytic conductive mating piece 14 and a positive electrolytic conductive mating piece 15. The negative electrolytic conductive mating piece 14 and the positive electrolytic conductive mating piece 15 are annular conductive pieces and are fixed to the top of the rotating cylinder 6. When the rotating cylinder 6 rotates, the negative conductive spring pin 12 and the positive conductive spring pin 13 are always in elastic conductive contact with the negative electrolytic conductive mating piece 14 and the positive electrolytic conductive mating piece 15, respectively.

[0038] 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 electrolytic conductive mating piece 14 and the positive electrolytic conductive mating piece 15 are in elastic conductive contact with the negative electrolytic conductive mating piece 14 and the positive electrolytic conductive mating piece 15 respectively as the rotating cylinder 6 rotates. This ensures effective electrical connection between the negative conductive spring pin 12 and the negative electrolytic conductive mating piece 14, and between the positive conductive spring pin 13 and the positive electrolytic conductive mating piece 15.

[0039] The electrolytic unit includes a negative electrolytic plate 16 and a positive electrolytic plate 17. The negative electrolytic plate 16 and the positive electrolytic plate 17 are respectively fixed at the bottom of the rotating cylinder 6. The negative electrolytic conductive mating plate 14 and the positive electrolytic conductive mating plate 15 are respectively electrically connected to the negative electrolytic plate 16 and the positive electrolytic plate 17 through conductive wires 7.

[0040] That is, the negative electrode conductive spring pin 12, the negative electrode electrolytic conductive mating piece 14, and the negative electrode electrolytic piece 16 are electrically connected to each other, and the positive electrode conductive spring pin 13, the positive electrode electrolytic conductive mating piece 15, and the positive electrode electrolytic piece 17 are electrically connected to each other. This allows the control board 4 to electrically connect the negative electrode electrolytic piece 16 and the positive electrode electrolytic piece 17, enabling the negative electrode electrolytic piece 16 and the positive electrode electrolytic piece 17 to obtain working power, and at the same time, the control board 4 can also control the negative electrode electrolytic piece 16 and the positive electrode electrolytic piece 17 to work.

[0041] In this embodiment, the control board 4 is equipped with an electrolysis generation module, which controls the negative electrode electrolytic plate 16 and the positive electrode electrolytic plate 17 to perform electrolysis. Alternatively, the control cavity 10 is equipped with an electrolysis generator, which is electrically connected to the control board 4 and the electrolysis conductive component 5. The electrolysis generator is controlled by the control board 4, and the electrolysis generator can control the negative electrode electrolytic plate 16 and the positive electrode electrolytic plate 17 to perform electrolysis.

[0042] A sealing element 18 is provided at the top opening of the rotating cylinder 6, and a top cover 19 is sealed and connected through the sealing element 18. A sealed cavity 20 is formed between the rotating cylinder 6 and the top cover 19, and the conductive wire 7 is located in the sealed cavity 20.

[0043] The rotating cylinder 6 and the top cover 19 are sealed together by a sealing element 18 to prevent the conductive wire 7 located in the sealed cavity 20 from being damaged by moisture.

[0044] In this embodiment, the electrolytic 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 electrolytic conductive mating piece 14, and the positive conductive spring pin 13 and the positive electrolytic conductive mating piece 15 are connected by low voltage, which is safe to use.

[0045] The top cover 19 has 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 electrolytic conductive mating piece 14 and the positive electrolytic conductive mating piece 15. The negative electrolytic conductive mating piece 14 and the positive electrolytic conductive mating piece 15 are respectively set on the annular positioning grooves 21. The connecting feet 23 extend into the sealed cavity 20 through the positioning holes 22 and are electrically connected to the conductive wire 7.

[0046] In this embodiment, the negative electrolytic conductive mating piece 14 and the positive electrolytic conductive mating piece 15 are arranged inside and outside, and they are respectively positioned on the positioning hole 22 through the connecting support 23, thereby being positioned on the inner and outer annular positioning grooves 21 respectively. The connecting support 23 also extends into the sealing cavity 20 through the positioning hole 22, and the conductive wire 7 is electrically connected to the connecting support 23.

[0047] 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.

[0048] 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 through the conductive fixing members 24. The conductive fixing members 24 pass through the rotating cylinder 6 and are electrically connected to the conductive wire 7.

[0049] 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, thereby realizing the mutual fixing of 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 holes of the rotating cylinder 6 and be electrically connected by the conductive wire 7.

[0050] 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.

[0051] 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, so that the rotating cylinder 6 uses the evenly distributed brushes 33 on the periphery to wash the fruits and vegetables when it rotates. 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 act elastically 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 towards the direction of the electronic control device A during rotation. This ensures that the negative electrode conductive spring pin 12 and the positive electrode conductive spring pin 13 are always in elastic conductive contact with the negative electrode electrolytic conductive mating piece 14 and the positive electrode electrolytic conductive mating piece 15, respectively, when the rotating cylinder 6 rotates.
