Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a fruit and vegetable purification device. Background Technology

[0002] Currently, most fruit and vegetable washing machines on the market use water hydroxyl technology, which generates hydroxyl free radicals with strong oxidizing properties through water electrolysis. This can efficiently and safely degrade pesticide residues and kill bacteria. However, the hydroxyl free radicals generated by electrolysis are diffused onto the fruits and vegetables through water to react, resulting in a slower cleaning speed. Moreover, hydroxyl free radicals are not very effective at cleaning dirt and stains adhering to the surface of fruits and vegetables, and cannot completely replace hand washing.

[0003] Some fruit and vegetable washing machines replace hand washing with mechanical action, using swirling water to remove impurities from the surface of fruits and vegetables. At the same time, electrolysis of water generates hydroxyl radicals, purifying toxic and harmful substances on the surface of fruits and vegetables. However, because household fruit and vegetable washing machines are generally small in size and weight, they are difficult to maintain stability in the swirling water flow. In addition, most fruit and vegetable washing machines have a single direction of swirling water flow, and the water flow forms a vortex that drives the fruits and vegetables to rotate. There is little force between the water flow and the fruits and vegetables, so the effect of cleaning the surface of fruits and vegetables by rinsing away impurities with water flow is poor.

[0004] Furthermore, fruit and vegetable washing machines typically immerse themselves in water to clean fruits and vegetables. The swirling water flow can mix dirt and grime, allowing it to enter the machine. When the water flow stops, some impurities also settle at the bottom and enter the machine's interior. Therefore, after using a fruit and vegetable washing machine, it is usually necessary to clean the machine itself. Although most fruit and vegetable washing machines support simple rinsing, they are not convenient for users to disassemble for deep cleaning. This increases users' concerns about the cleanliness of the machine and greatly reduces their enthusiasm for using it to clean fruits and vegetables. Utility Model Content

[0005] One advantage of this invention is that it provides a fruit and vegetable purification device, which is easy for users to operate by hand. The device controls the water flow to clean the fruits and vegetables and generates hydroxyl radicals to degrade and kill pesticide residues and bacteria on the surface of the fruits and vegetables.

[0006] One advantage of this invention is that it provides a fruit and vegetable purification device, wherein when the fruit and vegetable purification device rotates the water flow, the water flow forms multiple water flow paths under the drive of the fruit and vegetable purification device, and the water flow entering and exiting the fruit and vegetable purification device circulates and rolls to form a boiling diffusion of the water flow.

[0007] Another advantage of this invention is that it provides a fruit and vegetable purification device, wherein when the water flow is swirled to wash the surface of the fruit and vegetables, the fruit and vegetable purification device can remain stable in the water flow, and the hydroxyl radicals generated by the electrolysis of the fruit and vegetable purification device diffuse to the surface of the fruit and vegetables with the swirling water flow.

[0008] Another advantage of this invention is that it provides a fruit and vegetable purification device, wherein when the water flow is swirled, water with a low concentration of hydroxyl radicals in the vicinity is swirled into the fruit and vegetable purification device, while water with a high concentration of hydroxyl radicals located inside the fruit and vegetable purification device is swirled out of the fruit and vegetable purification device, thereby accelerating the diffusion of hydroxyl radicals and increasing the overall concentration of hydroxyl radicals.

[0009] Another advantage of this invention is that it provides a fruit and vegetable purification device, wherein the fruit and vegetable purification device includes a hydroxyl generator and a rotating component, and the positional design of the hydroxyl generator and the rotating component facilitates the rotating component to drive the water flow located near the hydroxyl generator.

[0010] Another advantage of this utility model is that it provides a fruit and vegetable purification device, wherein the structure of the fruit and vegetable purification device is designed to facilitate the user's one-handed control and adjustment of the operation of the fruit and vegetable purification device, thereby increasing the convenience of the user in operating the fruit and vegetable purification device.

[0011] Another advantage of this invention is that it provides a fruit and vegetable purification device, wherein the connection between the parts of the fruit and vegetable purification device that are easily contaminated with stains is detachable, which makes it convenient for users to disassemble multiple parts of the fruit and vegetable purification device for deep cleaning and to reassemble the disassembled parts themselves.

[0038] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0039] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0040] like Figure 1 As shown, according to the first preferred embodiment of the present invention, the fruit and vegetable purification device 100 includes: an annular rotating member 10, a hydroxyl generator 20, and a control body 30. The annular rotating member 10 surrounds and forms a receiving space 11. The hydroxyl generator 20 is located in the receiving space 11. The end of the control body 30 extends outward from the receiving space 11, and the outwardly extending end of the control body 30 forms a handle structure for gripping.

[0041] The control body 30 has a control key 31 extending outward at its end. The control key 31 controls and drives the annular rotating member 10 to rotate in a certain direction to rotate the water flow, and controls the start and stop of the hydroxyl generator 20. The hydroxyl generator 20 can electrolyze water to generate hydroxyl radicals. The water flow with a high concentration of hydroxyl radicals inside the hydroxyl generator 20 undergoes convection diffusion with the surrounding rotating water flow. The hydroxyl radicals diffuse outward with the rotating water flow to the surface of fruits and vegetables and purify them. The concentration of hydroxyl radicals near the hydroxyl generator 20 decreases, while the concentration of hydroxyl radicals in the overall water flow increases, thereby improving the reaction efficiency of the hydroxyl generator 20.

[0042] like Figure 2 and Figure 3 As shown, the fruit and vegetable purification device 100 also includes a filter ring cover 40 and a support ring seat 50. The annular rotating member 20 is arranged around the support ring seat 50. The bottom ring of the filter ring cover 40 is fixed between the annular rotating member 20 and the support ring seat 50. The top ring of the filter ring cover 40 is sleeved on the control body 30.

[0043] The support ring seat 50 is provided with a drive gear 51, which is located in the accommodating space 11. The annular rotating member 10 is provided with a transmission gear ring 12, which extends inward from the annular rotating member 10. The transmission gear ring 12 meshes with the drive gear 51 for transmission, and the drive gear 51 drives the annular rotating member 10 to rotate in the rotation direction.

[0044] The annular rotating component 10 includes a first blade group 13 and a support ring 14. The blades of the first blade group 13 are fixed to the support ring 14 in an annular array. When the annular rotating component 10 is driven to rotate, the blades of the first blade group 13 rotate the water flow to clean fruits and vegetables. The blades of the first blade group 13 protrude outward in an arc shape from the support ring 14 in a direction away from the accommodating space 11. In this way, during the rotation of the water flow in the fruit and vegetable purification device 100, impurities are unlikely to enter the annular rotating component 10 and affect the normal operation of the fruit and vegetable purification device 100.

[0045] like Figure 4 and Figure 5As shown, a fruit and vegetable purification device 100 according to a second preferred embodiment of the present invention is illustrated. The annular rotating member 10 includes a first blade group 13, a support ring 14, and a second blade group 15. The blades of the first blade group 13 and the blades of the second blade group 15 are respectively fixed to the upper and lower ends of the support ring 14 in an annular array. The ends of the blades of the first blade group 13 and the second blade group 15 near the accommodating space 11 are defined as the proximal ends of the blades. The blades of the first blade group 13 and the second blade group 15 extend from their proximal ends in opposite directions of rotation away from the accommodating space 11.

[0046] The blades of the first blade group 13 and the second blade group 15 are connected at their proximal ends. A first swirling cavity 131 is formed between any adjacent blades in the first blade group 13, and a second swirling cavity 151 is formed between any adjacent blades in the second blade group 15. The extension direction of the blades of the first blade group 13 is defined as the rotation direction. When the annular rotating member 10 is driven to rotate in the rotation direction, the liquid in the first swirling cavity 131 and the second swirling cavity 151 is swirled away.

[0047] The rotation direction of the annular rotating member 10 is the same as the rotation direction of the blades of the first blade group 13. When the first swirling water cavity 131 rotates the water flow, the contact area between its blades and the water flow is greater than the contact area between the second swirling water cavity 151 and the water flow. In this way, the water flow rotated by the first blade group 13 and the second blade group 15 forms a layer due to the different flow velocities, and then the water flow rolls and spreads outward.

[0048] like Figures 6 to 8 As shown, a fruit and vegetable purification device 100 according to a third preferred embodiment of the present invention is illustrated, wherein the first blade group 13 and the second blade group 15 communicate with the accommodating space 11, and the hydroxyl generator 20 is adapted to extend into the accommodating space 11.

[0049] The annular rotating member 10 further includes a top support ring 16 and a bottom support ring 17. The blades of the first blade group 13 are respectively fixed between the top support ring 16 and the support ring 14. The blades of the second blade group 15 are respectively fixed between the bottom support ring 17 and the support ring 14. The support ring 14 is provided with a first channel 141, and the bottom support ring 17 is provided with a second channel 171. The first channel 141 communicates with the second channel 171.

[0050] The hydroxyl generator 20 includes a generator 21 and a generating chamber 22. The generating chamber 22 is fixed to the end of the control body 30 near the accommodating space 11. The generator 21 is disposed inside the generating chamber 22. A plurality of first filter chambers 23 are distributed at the end of the generating chamber 22. Water flows through the first filter chambers 23 to filter impurities and enter the generating chamber 22.

[0051] The fruit and vegetable purification device 100 further includes a filter ring cover 40, which is adapted to be fitted onto the generating chamber 22. The filter ring cover 40 includes an outer ring cover 41 and an inner ring cover 42. The first end of the outer ring cover 41 extends to the first end of the inner ring cover 42 located on the same side. The outer ring cover 41 and the inner ring cover 42 surround to form a filter chamber 43. The second ends of the outer ring cover 41 and the inner ring cover 42 serve as the openings of the filter chamber 43. The openings of the filter chamber 43 face the annular rotating member 10. The outer ring cover 41 and the inner ring cover 42 are respectively provided with a plurality of second filter chambers 44. Water from the outside enters and exits the filter chamber 43 through the plurality of second filter chambers 44.

[0052] like Figure 9 As shown, the extension direction of the blades of the second blade group 15 is defined as the rotation direction. When the annular rotating member 10 is driven to rotate in the rotation direction, the second blade group 15 continuously absorbs water flow during the rotation process. Part of the water flow enters the filter chamber 43 through the second channel 171 and flows out of the filter chamber 43. Another part of the water flow enters the first blade group 13 through the first channel 141 and is accelerated to flow out under the rotation of the blades of the first blade group 13. The water flow exhibits boiling diffusion. The high concentration of hydroxyl radicals in the generating chamber 22 diffuses from the first filter chamber 23 and the second filter chamber 44 to the filter chamber 43 and mixes with the liquid flowing from the second channel 171 to the filter chamber 43 through convection. Then, with the boiling diffusion of the water flow, it diffuses to the surface of fruits and vegetables.

[0053] Specifically, the inner ring cover 42 surrounds to form a receiving cavity 421, which is adapted to accommodate the generating cavity 22. The filter ring cover 40 is sleeved on the generating cavity 22 through the inner ring cover 42. When the annular rotating member 10 is driven to rotate in the rotation direction, the annular rotating member 10 is located on top of the filter ring cover 40 to drive the water flow. During the process of the water flow to the generator 21, impurities are filtered through the first filter cavity 23 and the second filter cavity 44. The hydroxyl radicals generated by the reaction between the generator 21 and water diffuse outward with the water flow.

[0054] like Figure 7As shown, the fruit and vegetable purification device 100 also includes a suction cup 60. The suction cup 60 extends outward from the first end of the inner ring cover 42. When the inner ring cover 42 is fitted onto the generating cavity 22, the generating cavity 22 closes the receiving cavity 421. In this way, the bottom of the suction cup 60 is in a closed state. When the suction cup 60 is pressed against the flat surface, the suction cup 60 generates an internal and external pressure difference through elastic deformation. The force brought about by the pressure difference stabilizes the fruit and vegetable purification device 100 in the boiling diffusion water.

[0055] like Figure 8 As shown, when disassembling and cleaning the fruit and vegetable purification device 100, the annular rotating member 10 and the filter ring cover 40 are separated from the generating chamber 22, and the annular rotating member 10, the filter ring cover 40 and the hydroxyl generator 20 are deeply cleaned respectively. Then, the annular rotating member 10 and the filter ring cover 40 are sequentially fitted onto the generating chamber 22.

[0056] like Figure 10 The image shows a fourth preferred embodiment of the fruit and vegetable purification device 100 of this utility model. The first blade group 13 and the second blade group 15 are connected to the accommodating space 11, and the accommodating space 11 is connected to the hydroxyl generator 20. When the annular rotating member 10 is driven to rotate in the rotation direction, the second blade group 15 continuously absorbs water flow during the rotation process. The water flow enters the hydroxyl generator 20 through the first filter chamber 23 and the second filter chamber 44, diluting and diffusing the hydroxyl free radicals generated by the electrolysis of water in the generator 21. Under the rotation action of the first blade group 13, a part of the water flow in the generating chamber 22 is accelerated outward from the generating chamber 22, and the water flow exhibits boiling diffusion.

[0057] Driven by the rotation of the annular rotating member 10, water from the outside is filtered through the second filter chamber 44 located on the outer ring cover 41 and enters the filter chamber 43. Water in the filter chamber 43 undergoes secondary filtration through the first filter chamber 23 and the second filter chamber 44 located on the inner ring cover 42 before entering the interior of the generating chamber 22. In this way, large impurities deposited at the bottom and mixed in the water are difficult to pass through the first filter chamber 23 and the second filter chamber 44 to enter the generator 21, thus affecting the operation of the generator 21. The hydroxyl radicals generated by the electrolysis of water by the generator 21 diffuse outward from the generating chamber 22 along with the boiling diffusion water and purify the fruits and vegetables.

[0058] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention.

[0059] Therefore, it can be seen that the objective of this utility model has been fully and effectively achieved. The function and structural principle of this utility model have been shown and described in the embodiments. Without departing from the stated principle, the implementation of this utility model may have any variations or modifications.
