[0022] In related technologies, cleaning devices for fruits and vegetables typically include a first cleaning tank and a second cleaning tank. The first cleaning tank is used for a rough wash, using tap water to remove dirt and other substances from the fruits and vegetables. The second cleaning tank is used for a fine wash, and it is equipped with an aeration unit and an ozone generator to create ozone-rich water containing bubbles, thereby removing residual pesticides and other harmful substances from the fruits and vegetables. After cleaning, the water in the first and second cleaning tanks is discharged to the outside, resulting in a waste of water resources.

[0023] Reference Figures 1 to 3 and combined Figure 5 A cleaning device according to one embodiment of the present invention includes a frame 100, a first cleaning tank 110, a second cleaning tank 120, a connecting pipe 200, a bubble generating unit, an ozone generator 320, and a filter. The first cleaning tank 110 is disposed on the frame 100 and has a first inlet and a first outlet. The second cleaning tank 120 is disposed on the frame 100 and has a second inlet and a second outlet. The second cleaning tank 120 is connected to the first cleaning tank 110 through the connecting pipe 200. The bubble generating unit is disposed on the frame 100 and generates bubbles... The generating unit is used to generate bubbles in the second cleaning tank 120. The ozone generator 320 is installed on the frame 100 and is used to generate ozone in the second cleaning tank 120. The filter is installed on the connecting pipe 200 and is used to filter out the grease attached to the water flowing from the second cleaning tank 120 into the connecting pipe 200. After the fine wash water containing ozone and bubbles in the second cleaning tank 120 is filtered to remove the grease, it can be transported to the first cleaning tank 110 as coarse wash water. Water resources can be recycled, water waste can be reduced, and water utilization efficiency can be improved.

[0024] For example, when washing fruits and vegetables, they undergo a rough wash in the first washing tank 110. After the rough wash, the fruits and vegetables are transferred to the second washing tank 120. The bubble generating unit and ozone generator 320 are activated to generate fine wash water containing ozone and bubbles. The fine wash water can remove pesticide residues from the surface of the fruits and vegetables. After the fine wash is completed, the fine wash water in the second washing tank 120 can be returned to the first washing tank 110 through the connecting pipe 200. Since the fine wash water passes through a filter, the ozone and bubble-containing fine wash water in the second washing tank 120 can be transported to the first washing tank 110 as rough wash water after the grease is removed by filtration. Water resources can be recycled, which can reduce water waste and improve water utilization.

[0025] It should be noted that in this embodiment, by setting up a bubble generating unit and an ozone generator 320, pesticide residues on the surface of fruits and vegetables can be removed without the use of chemical cleaners, which can improve the user experience.

[0026] In this embodiment, the bubble generator 310 includes a nozzle and a bubble generator 310. The bubble generator 310 is disposed on the frame 100, and the nozzle is disposed in the second cleaning tank 120. The output end of the bubble generator 310 is connected to the nozzle. Multiple nozzles are configured and the multiple nozzle arrays are arranged at intervals, which can significantly increase the coverage area and distribution density of bubbles in the second cleaning tank 120, so that the ozone water has more sufficient and uniform contact with the surface of fruits and vegetables, thereby comprehensively improving the cleaning efficiency and cleaning effect of pesticides and other harmful substances.

[0027] In this embodiment, a phase controller is also included. The phase controller is electrically connected to the bubble generator 310. The phase controller is used to make one of the two adjacent nozzles spray bubbles while the other nozzle does not spray bubbles, which can generate a phase-shifted airflow. On the one hand, it can avoid fluid interference and energy cancellation that may be caused by all nozzles working at the same time, making the water flow field more stable and the bubble distribution more uniform. On the other hand, it can reduce the instantaneous power and energy consumption of the bubble generating unit, thus achieving the effect of energy saving.

[0028] In this embodiment, the filter includes a first housing 410, a second housing 420, and a third housing 430. The first housing 410 has a first cavity, the second housing 420 has a second cavity, and the third housing 430 has a third cavity. The first housing 410, the second housing 420, and the third housing 430 are respectively disposed on the connecting pipe 200, and are arranged sequentially at intervals from the second cleaning tank 120 to the first cleaning tank 110. A coarse filter element is disposed in the first cavity. The second chamber contains activated carbon, and the third chamber contains an electrolysis unit. The electrolysis unit can electrolyze the water in the third chamber to form water with hydroxide ions, which can effectively decompose oil and some organic pollutants in the water. The coarse filter can filter out particulate impurities in the water. The activated carbon can adsorb odors, residual chlorine and small molecule organic matter in the water. This multi-stage synergistic filtration mechanism ensures that the water flowing back from the second cleaning tank 120 to the first cleaning tank 110 is clean, avoids secondary pollution caused by dirty water circulation, and ensures the basic cleaning effect of the coarse cleaning stage.

[0029] In this embodiment, the cleaning device further includes an ultrasonic cleaning unit. The ultrasonic waves emitted by the ultrasonic cleaning unit radiate upwards and are opposite to the water inlet direction of the second water inlet. The ultrasonic waves generated by the ultrasonic cleaning unit can form countless tiny cavitation bubbles in the water. The impact force generated when these bubbles burst can penetrate deep into the crevices of the fruit and vegetable surface, powerfully removing deep-seated pesticide residues and dirt. Moreover, the direction of ultrasonic radiation is opposite to the water inlet direction, which can increase water flow disturbance, prevent dirt from settling, and make the cleaning more thorough, further improving the ability to remove stubborn pesticides. It should be noted that the vibration frequency of the ultrasonic cleaning unit is greater than or equal to 20kHz and less than or equal to 100kHz. The ultrasonic cleaning unit is synchronously excited with the bubble generator 310, which can form micro-jets and micro-cavitation, thereby improving the fine washing effect of fruits and vegetables. It is understood that the vibration frequency of the ultrasonic cleaning unit is preferably greater than or equal to 40kHz and less than or equal to 60kHz, but no limitation is imposed here.

[0030] In this embodiment, a support member 510 and a swing mechanism are also included. The support member 510 is disposed in the second cleaning tank 120. The support member 510 is provided with a support groove 511 and a plurality of through holes that connect the support groove 511. The through holes connect to the second cleaning tank 120. The swing mechanism passes through the second cleaning tank 120 and is connected to the support member 510 so that the support member 510 can swing through the swing of the swing mechanism.

[0031] Reference Figure 3 , Figure 4In this embodiment, the swing mechanism includes a rocker arm 520, a rocker arm seat 530, and a drive assembly 540. The rocker arm seat 530 is disposed on the frame 100, and the rocker arm 520 passes through the bottom of the second cleaning tank 120. The upper end of the rocker arm 520 is connected to the support member 510, and the lower end of the rocker arm 520 is connected to the rocker arm seat 530. The drive assembly 540 is used to drive the rocker arm 520 to swing relative to the rocker arm seat 530, so as to drive the support member 510 to swing. This can dynamically change the position and posture of fruits and vegetables in the water, so that all surfaces of fruits and vegetables can be exposed to ozone-containing bubble water without dead angles, avoiding the cleaning blind spots that may exist in traditional static cleaning, thereby achieving all-round and uniform cleaning.

[0032] In this embodiment, the minimum angle between the axis of the rocker arm 520 and the vertical direction is θ, which satisfies: 0°<θ≤45°. This ensures that the carrier 510 generates a sufficient amplitude and effective swing, which not only ensures the uniformity of cleaning, but also avoids the fruits and vegetables from falling off the carrier 510 or being damaged by collision due to excessive swing angle. The best balance is achieved between cleaning effect and protection of fruits and vegetables.

[0033] It should be noted that, according to the instructions of the control module, the drive component automatically adjusts the value of θ, which can dynamically change the position and posture of fruits and vegetables in the water, and no restrictions are imposed here.

[0034] In this embodiment, the rocker arm seat 530 is provided with a spherical groove 530, and the lower end of the rocker arm 520 is provided with a spherical protrusion 521. The spherical protrusion 521 is accommodated in the spherical groove and abuts against the side wall of the spherical groove, providing a flexible multi-directional swing fulcrum for the rocker arm 520. This not only ensures that the rocker arm 520 can swing smoothly in all directions, but also has a large spherical contact area, less wear, and improves the service life and reliability of the rocker mechanism.

[0035] In this embodiment, the frame 100 is equipped with a control unit, and the second cleaning tank 120 is equipped with an acceleration detection sensor, an angle detection sensor, a camera, a water quality turbidity meter, a conductivity detection sensor, and a bubble density meter. The acceleration detection sensor is used to detect the acceleration of the bubbles, the angle detection sensor is used to detect the tilt angle of the support component, the camera is used to observe the second cleaning tank 120 in real time, the water quality turbidity meter is used to detect the turbidity of the water in the second cleaning tank 120, the conductivity detection sensor is used to detect the conductivity of the water in the second cleaning tank 120, and the bubble density meter is used to detect the density of the bubbles. The control unit realizes intelligent control of the cleaning device based on the feedback from the acceleration detection sensor, the angle detection sensor, the camera, the water quality turbidity meter, the conductivity detection sensor, and the bubble density meter.

[0036] Understandably, by setting up an array of nozzles, the nozzles can spray a stream of bubbles in a preset direction to form a directional microjet. The nozzles support pulsed spraying or synchronous spraying, which is not limited here.

[0037] In this embodiment, a flexible component is also included. The flexible component is disposed in the bearing groove 511 and extends circumferentially along the bearing groove 511. The flexible component has multiple mesh holes and is flexible. The multiple mesh holes ensure the smooth flow of water and air bubbles. Moreover, the flexibility of the flexible component specifically refers to the ability to buffer the collision and friction between the fruits and vegetables and the bearing component 510 during the swaying process, effectively preventing the fruits and vegetables (especially delicate fruits such as strawberries and blueberries) from being scratched or bruised during the washing process, and playing an important protective role for the fruits and vegetables.

[0038] It should be noted that in this embodiment, when washing fruits and vegetables, the carrier 510 can dynamically change the tilt angle, that is, θ changes within the range of 0° to 45°. Multiple nozzle arrays are set to be triggered by a predetermined phase difference pulse to form a directional micro-jet, so that the cleaning force is concentrated on the stain surface. Moreover, the frequency of the phase controller is the same as the vibration frequency of the ultrasonic cleaning unit, which can increase the local cleaning force of the cleaning device.

[0039] It should be noted that by establishing a synchronous control relationship between the phase controller and the drive circuit of the ultrasonic cleaning unit, a specific phase is selected to trigger the bubble pulse within the vibration cycle of the ultrasonic cleaning unit, so as to achieve the optimal phase of bubble collapse, maximize the local shearing and impact on the surface of fruits and vegetables, and increase the local cleaning power of the cleaning device.

[0040] It should be noted that the control unit can control the injection and vibration phases at the millisecond level, and no limitation is made here.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
