[0002] The fruit and vegetable purifier generates oxidizing potential water through electrode sheets, which is used by families to remove bacteria and degrade pesticides on tableware, fruits, vegetables, general object surfaces, and textiles.

[0003] The hydroxyl (-OH), chlorine (Cl2), hypochlorite (ClO - ), chlorite (ClO2 - ), oxygen atom (O), oxygen (O2), ozone (O3), etc. in the plasma with strong oxidizing ability generated by the anode reaction can oxidize and denature the nucleic acid or protein components of bacteria and viruses to lose biological activity, especially for common E. coli, staphylococcus, salmonella, and candida.

[0004] The residual pesticides of food materials are heavy metals and organic substances. The residual pesticides of heavy metals are dialyzed and peeled off by small molecular group water, and are reduced to metal bodies by hydrogen (H2) generated by water electrolysis and retained in water; the residual pesticides of organic substances have different types, which can be degraded by being neutralized by hydroxide (OH - ) for acid type, reduced by hydrogen (H2) for oxidizing type, and oxidized by hydroxyl (-OH), chlorine (Cl2), hypochlorite (ClO - ), chlorite (ClO2 - ), oxygen atom (O), oxygen (O2), and ozone (O3) for reducing type.

Implementation

[0035] The following is combined with Figures 1 to 7 The present invention will be further described as follows:

[0036] like Figure 1 As shown, a fruit and vegetable purifier includes an electrolytic plate, which is composed of multiple cathode electrolytic plates 13 and multiple anode electrolytic plates 14. An anode electrolytic plate 14 is provided between two adjacent cathode electrolytic plates 13, and a cathode electrolytic plate 13 is provided between two adjacent anode electrolytic plates 14. The multiple anode electrolytic plates 14 and multiple cathode electrolytic plates 13 are respectively connected to the positive and negative terminals of a battery 31. The device also includes a probe 21, which forms a circuit with the anode electrolytic plates 14 in the washing water to generate an electrical signal.

[0037] Electrolytic plates are mounted on electrode holders 15, and multiple cathode electrolytic plates 13 and multiple anode electrolytic plates 14 can be fixed to electrode holders 15 by connecting screws 16. Electrode covers are provided around the electrolytic plates, and the electrode covers consist of a front electrode cover 11 and a rear electrode cover 12.

[0038] The probe 21 is also mounted on the electrode holder 15. The probe 21 is made of titanium or stainless steel. The upper end of the probe 21 has a probe sleeve 22, and the lower end of the probe 21 is connected to a PCB circuit board 25, which contains signal conditioning circuitry. The PCB circuit board 25 is fixed to the battery holder 32 by connecting studs 23 and nuts 24. The battery holder 32 holds the battery 31 and has a wireless charging ring 33 at its bottom. The display screen 41 is mounted on the battery holder 32 and is placed together with the battery holder 32 in the cavity of the bottom cover 51. The bottom cover 51 is translucent, allowing the information displayed on the display screen 41 to be shown through the bottom cover 51.

[0039] The distance between the probe 21 and any anode electrolytic plate 14 is greater than the distance between that anode electrolytic plate 14 and its adjacent cathode electrolytic plate 13. A probe 21 is located on one side of the electrolytic plate, and a counterweight is located below the probe 21. This counterweight ensures that the center of gravity of the fruit and vegetable purifier is positioned to one side of the probe 21. When the fruit and vegetable purifier is placed in the washing water, the buoyancy of the water and the center of gravity of the purifier ensure that the probe 21 remains below the electrolytic plate, guaranteeing that the central processing unit can accurately determine whether the fruit and vegetable purifier is submerged in water.

[0040] A display screen 41 is provided on the other side of the electrolytic plate. When the fruit and vegetable purifier is thrown into the washing water, the buoyancy of the washing water and the center of gravity of the fruit and vegetable purifier cause the display screen 41 to be located at the top and facing upwards, the electrolytic plate to be located in the middle, and the probe 21 to be located at the bottom.

[0041] The battery 31 is located in the bottom cover 51, and the electrode fixing seat 15 is above the bottom cover 51. The two form a column. The electrolytic plate and the probe 21 are located on the top surface of the column. The display screen 41 is located in the bottom cover 51 or the electrode fixing seat 15.

[0042] like Figure 4 As shown, the electrical signal generated by the circuit formed by the probe 21 and the anode electrolytic plate 14 in the cleaning water is sent to the central processing unit. The central processing unit determines whether the fruit and vegetable purifier is in the cleaning water based on the voltage value of the electrical signal. When the determination result is positive, the central processing unit controls the voltage between the cathode electrolytic plate 13 and the anode electrolytic plate 14 in the cleaning water to generate oxidation potential water.

[0043] A signal conditioning circuit is also provided between the probe and the central processing unit. When the probe signal is weak and is affected by external environmental interference, the signal conditioning circuit filters, amplifies, and shapes the probe signal to provide it to the central processing unit, so that the central processing unit can detect and process it accurately.

[0044] The constant current output voltage adjustment circuit adjusts the voltage between the anode electrolytic plate 14 and the cathode electrolytic plate 13. The control signal for the constant current output voltage adjustment circuit comes from the central processing unit.

[0045] like Figure 5 As shown, the counterweight is battery 31. When there are three batteries 31, ensure that the center of gravity of the fruit and vegetable purifier is below the center line L, which is the side where the probe 21 is located, and above the center line L is the location of the display screen 41.

[0046] like Figure 6 As shown, the counterweight is battery 31. When there are two batteries 31, ensure that the center of gravity of the fruit and vegetable purifier is below the center line L, which is the side where the probe 21 is located, and above the center line L is the location of the display screen 41.

[0047] like Figure 7 As shown, the counterweight is battery 31. When there is only one battery 31, ensure that the center of gravity of the fruit and vegetable purifier is below the center line L, which is the side where the probe 21 is located, and above the center line L is the location of the display screen 41.

[0048] The control principle of the fruit and vegetable purifier of this invention is as follows:

[0049] When the fruit and vegetable purifier is thrown into the washing water, the buoyancy of the washing water and the center of gravity of the fruit and vegetable purifier are located on one side of the probe 21, so that the probe 21 is located below the electrolytic plate.

[0050] The electrical signal generated by the circuit formed by the probe 21 and the anode electrolysis plate 14 in the cleaning water is sent to the central processing unit. The central processing unit determines whether the fruit and vegetable purifier is in the cleaning water based on the voltage value of the electrical signal. If the determination is positive, the central processing unit controls the voltage between the cathode electrolysis plate 13 and the anode electrolysis plate 14 in the cleaning water to generate oxidized potential water.

[0051] The display screen 41 is located above the electrolytic plate and faces upwards, displaying the working time and working status.

[0052] In other words, users simply need to add the fruit and vegetable purifier to the washing water, without needing to worry about whether it's turned on or off. Furthermore, users can always see the purifier's operating status and running time on the upward-facing display screen.

[0053] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
