Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning and disinfection equipment, specifically relating to a micro-nano ozone bubble fruit and vegetable cleaning device. Background Technology

[0002] People clean fruits and vegetables before eating them, partly to kill bacteria and disinfect them, and partly to remove any pesticide residues. However, traditional cleaning methods are often insufficient to completely eliminate bacteria and remove pesticide residues, posing certain health risks to people.

[0003] To address this, various cleaning solutions have been proposed, including micro-nano ozone bubble water, among others. However, these solutions still have certain loopholes and shortcomings in practical application. For example, when there are a large quantity of fruits and vegetables, uneven distribution of the micro-nano ozone bubble water and overlapping of fruits and vegetables can lead to some fruits and vegetables not being adequately disinfected. Furthermore, traditional micro-nano ozone bubble water often contains insufficient ozone to meet the required level for effective disinfection; specifically, the number of micro-nano bubbles per cubic centimeter is unlikely to reach 50,000.

[0004] Based on this, the inventors have conducted in-depth research on fruit and vegetable cleaning equipment that utilizes micro-nano ozone to sterilize water and eliminate pesticide residues. The aim is to achieve thorough cleaning of fruits and vegetables by setting up a more reasonable structural device, ensuring that the cleaned fruits and vegetables are completely sterile and free of pesticide residues. Utility Model Content

[0005] To overcome the above problems, the inventors conducted in-depth research and designed a micro-nano ozone bubble fruit and vegetable cleaning device. This device is equipped with a micro-nano ozone system that injects micro-nano ozone bubble water into a water tank, gradually replacing the water in the tank with micro-nano ozone bubble water. The device also includes an air pump that blows air in from the bottom of the tank, using the kinetic energy of the rising bubbles to force the fruits and vegetables to tumble in the tank for a deeper cleaning. In addition, a spray pump is provided to draw water from the bottom of the tank and spray it out from the spray pipe above the tank to rinse the fruits and vegetables, further improving the cleaning effect, thus completing this utility model.

[0006] Specifically, the purpose of this invention is to provide a micro-nano ozone bubble fruit and vegetable cleaning device, which includes a water tank 1, an air pump 2, a spray pump 3, and a micro-nano ozone system.

[0007] The water tank 1 holds the washing water, and a basket 4 is set in the water tank 1 to hold the fruits and vegetables to be washed.

[0008] The air outlet of the air pump 2 is connected to the bottom of the water tank 1, located below the basket 4. The air bubbles sprayed from the air pump 2 push the fruits and vegetables to tumble and wash in the basket 4.

[0009] The inlet pipe of the spray pump 3 is connected to the water tank 1, and a spray head is provided on the outlet pipe of the spray pump 3. The spray head is installed above the water tank 1, and the fruits and vegetables are washed by the spray pump 3 and the spray head.

[0010] The micro-nano ozone system includes an ozone generator 5, through which micro-nano ozone bubbles are injected into the water tank 1.

[0011] The micro-nano ozone system includes a micro-nano high-speed rotary shear pump 6, the inlet of which is connected to the water tank 1 and the ozone generator 5.

[0012] Water and ozone gas are simultaneously drawn in by the micro-nano high-speed rotary pump 6, and the ozone gas and water are fully mixed by the high-speed blades and sent into the energy storage tank 7 for energy storage.

[0013] A micro-nano bubble micropore pressure generator 8 is connected to the air outlet of the energy storage tank 7, and the air outlet of the micro-nano bubble micropore pressure generator 8 is connected to the bottom of the water tank 1.

[0014] The ozone bubble water in the energy storage tank 7 is pressurized a second time by the micro-nano bubble micropore pressurization generator 8 to obtain high-density micro-nano bubbles, and the high-density micro-nano bubbles are then transported to the water tank 1.

[0015] The micro-nano bubble micropore pressurization generator 8 is equipped with a micro-nano bubble pressurization head 9, and a deceleration buffer net 10 is set near the outlet of the micro-nano bubble pressurization head 9. The deceleration buffer net 10 promotes the micro-nano bubble water and ozone gas to re-merge, thereby increasing the ozone content in the micro-nano bubbles.

[0016] The deceleration buffer mesh 10 has a mesh size of 200μm and a thickness of 0.2mm.

[0017] The deceleration buffer net 10 reduces the flow rate of micro-nano ozone bubble water from over 10 m / s to below 1 m / s, thereby improving the integration degree of micro-nano bubble water.

[0018] An automatic exhaust valve 11 is provided on the energy storage tank 7 to discharge excess gas from the energy storage tank 7.

[0019] An air pump 12 and a glass rotor flow meter 13 are provided between the ozone generator 5 and the micro-nano high-speed rotary cutter pump 6 to control the amount of ozone gas entering the micro-nano high-speed rotary cutter pump 6.

[0020] A pre-air filter 14 is provided between the micro-nano high-speed rotary cutter pump 6 and the water tank 1 to block impurities in the water from entering the micro-nano high-speed rotary cutter pump 6.

[0021] The air pump 2 has multiple parallel air guide pipes 15 at its outlet, and each air guide pipe 15 has multiple air outlets 16. The angle between the air outlets and the vertical direction is 45°.

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent.

[0048] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0049] This invention provides a micro-nano ozone bubble fruit and vegetable cleaning device, such as... Figure 1 and Figure 2 As shown, the device includes a water tank 1, an air pump 2, a spray pump 3, and a micro / nano ozone system.

[0050] The washing water, which can be tap water, is collected in the water tank 1. A basket 4 is set in the water tank 1 to hold the fruits and vegetables to be washed. The basket 4 has dense holes on its wall to allow water to freely enter and exit the basket. The basket 4 is completely embedded in the water tank 1 so that the fruits and vegetables in the basket 4 are completely immersed in the water.

[0051] The air outlet of the air pump 2 is connected to the bottom of the water tank 1, located below the basket 4. The air bubbles sprayed from the air pump 2 push the fruits and vegetables to tumble and clean in the basket 4, thus achieving a deeper cleaning effect on the fruits and vegetables.

[0052] The inlet pipe of the spray pump 3 is connected to the water tank 1, and a spray head is provided on the outlet pipe of the spray pump 3. The spray head is installed above the water tank 1. The fruits and vegetables are washed by the spray pump 3 and the spray head. The spray head can spray a high-pressure jet, which can wash the fruits and vegetables with high intensity and also help the fruits and vegetables to roll.

[0053] The micro-nano ozone system includes an ozone generator 5, which generates ozone gas and injects micro-nano ozone bubbles into the water tank 1. In this application, "bubble water" refers to water containing tiny bubbles. When the bubble diameter is less than 100 μm, it is called micron-bubble water; when the bubble diameter is less than 100 nm, the bubble water is called nanobubble water. Micro-nano bubble water refers to water with bubbles in diameter between tens of micrometers and hundreds of nanometers. When the gas in these bubbles is ozone gas, it is called micro-nano ozone bubble water.

[0054] In a preferred embodiment, the micro / nano ozone system includes a micro / nano high-speed rotary slitting pump 6, the inlet of which is connected to the water tank 1 and the ozone generator 5.

[0055] Water and ozone gas are simultaneously drawn in by the micro-nano high-speed rotary pump 6, and the ozone gas and water are fully mixed by the high-speed blades and sent into the energy storage tank 7 for energy storage.

[0056] A micro-nano bubble micropore pressure generator 8 is connected to the air outlet of the energy storage tank 7, and the air outlet of the micro-nano bubble micropore pressure generator 8 is connected to the bottom of the water tank 1.

[0057] The micro-nano bubble micropore pressurization generator 8 applies secondary pressurization to the ozone bubble water in the energy storage tank 7, forcing the flow rate of the micro-nano ozone bubble water in the pipeline to increase, resulting in high-density micro-nano bubbles. These high-density micro-nano bubbles are then transported to the water tank 1, and after a period of time, the water in the tank is replaced with micro-nano ozone bubble water.

[0058] Preferably, such as Figure 2As shown, a micro-nano bubble pressurizing head 9 is provided in the micro-nano bubble micropore pressurizing generator 8. A deceleration buffer net 10 is provided near the outlet of the micro-nano bubble pressurizing head 9. The deceleration buffer net 10 promotes the re-fusion of micro-nano bubble water and ozone gas, thereby increasing the ozone content in the micro-nano bubbles. In this application, the deceleration buffer net 10 plays a key role in the concentration of micro-nano bubbles formed later. After the micro-nano bubble mixed water is pressurized in the micro-nano bubble micropore pressurizing generator 8, a high-speed jet is generated. The jet sprays inside the micro-nano bubble pressurizing head 9 and forms an axial vortex in front of the deceleration buffer net 10, forcing the gas-liquid mixed water to fuse at high speed here. The water flowing out after passing through the deceleration buffer net 10 is the thoroughly fused micro-nano bubble water. If the micro-nano bubble micropore pressurizing generator 8 is not provided with the deceleration buffer net 10, only gas-liquid mixed water of different sizes will be sprayed out from the micro-nano bubble micropore pressurizing generator 8.

[0059] Preferably, such as Figure 2 As shown, the mesh size of the deceleration buffer mesh 10 is 200μm, and the thickness of the deceleration buffer mesh 10 is 0.2mm;

[0060] The deceleration buffer net 10 reduces the flow rate of micro-nano ozone bubble water from over 10 m / s to below 1 m / s, thereby improving the integration degree of micro-nano bubble water.

[0061] Preferably, an automatic exhaust valve 11 is provided on the energy storage tank 7 to discharge excess gas from the energy storage tank 7.

[0062] Preferably, an air pump 12 and a glass rotor flow meter 13 are provided between the ozone generator 5 and the micro-nano high-speed rotary cutter pump 6 to control the amount of ozone gas entering the micro-nano high-speed rotary cutter pump 6.

[0063] Preferably, a pre-filter 14 is provided between the micro-nano high-speed rotary cutter pump 6 and the water tank 1. The pre-filter 14 blocks impurities in the water from entering the micro-nano high-speed rotary cutter pump 6, thereby preventing foreign objects from being sucked into the micro-nano high-speed rotary cutter pump 6 and preventing damage to the blades of the micro-nano high-speed rotary cutter pump 6.

[0064] Preferred, such as Figure 3 and Figure 4 As shown, multiple parallel air guide pipes 15 are provided at the air outlet of the air pump 2, and multiple air outlets 16 are provided on each air guide pipe 15. The angle between the air outlet and the vertical direction is 45°. The air guide pipes 15 and air outlets 16 are used to control the generation position and initial velocity direction of the bubbles at the bottom of the water tank 1, thereby improving the tumbling efficiency of the fruits and vegetables in the basket 4.

[0065] In this application, the main function of micro-nano bubbles is to cavitate and explode the surface of fruits and vegetables, instantly removing pesticide residues. Some of the bubbles suspend the removed dirt on the water surface. The ozone in the exploded micro-nano bubbles mainly serves a sterilization and disinfection function. The micro-nano ozone bubble water introduced into the water tank contains approximately 50,000 micro-nano bubbles per cubic centimeter, with a lifespan of 180-200 seconds, effectively removing pesticide residues and dirt deeply.

[0066] Specific calculations show that:

[0067] Sterilization and disinfection effect on vegetables: After 9 minutes of operation, the micro-nano ozone system achieved kill rates of 99.96%, 98.00%, and 98.13% for Escherichia coli, Staphylococcus aureus, and Salmonella contaminating vegetables (Shanghai bok choy), respectively.

[0068] Sterilization and disinfection effect on fruits: After 9 minutes of operation, the micro-nano ozone system achieved average kill rates of 98%, 92%, and 97.34% for Escherichia coli, Staphylococcus aureus, and Salmonella contaminating the surface of fruits (grapes).

[0069] Pesticide residues, also known as pesticide residues, refer to the phenomenon where some pesticides remain directly or indirectly in grains, vegetables, fruits, livestock products, aquatic products, soil, and water bodies after pesticide use.

[0070] The specific types of pesticide residues are as follows:

[0071] Organophosphorus pesticides: such as dimethoate, trichlorfon, dichlorvos, etc.

[0072] Organochlorine pesticides: such as hexachlorocyclohexane (HCH) and DDT.

[0073] Pyrethroid pesticides: such as bifenthrin, dichlorvos, etc.

[0074] Herbicides: such as diquat, terbuchlor, etc.

[0075] Methyl carbamate pesticides: such as carbaryl and aldicarb.

[0076] Other types of pesticides, such as sulfadiazine and emamectin benzoate.

[0077] Shanghai bok choy and grapes with pesticide residues were placed in a basket. After the micro-nano ozone system was activated for 9 minutes, the test showed that there were no pesticide residues remaining.

[0078] The present invention has been described above with reference to preferred embodiments; however, these embodiments are merely exemplary and serve only an illustrative purpose. Based on this, various substitutions and improvements can be made to the present invention, all of which fall within the protection scope of the present invention.
