Description

Technical Field

[0001] This invention relates to the field of disinfection device technology, specifically a plasma-activated fog disinfection device. Background Technology

[0002] It is suitable for highly efficient, broad-spectrum, rapid, and environmentally friendly disinfection of air, object surfaces, and even water bodies, especially in places with high cleanliness or epidemic prevention requirements such as medical care, public health, food processing, cold chain transportation, public places, and transportation vehicles. However, chemical residues of chlorine-containing disinfectants (such as 84 disinfectant), peroxides (such as peracetic acid and hydrogen peroxide), alcohols (such as ethanol), aldehydes (such as formaldehyde), and quaternary ammonium salts may pose health risks (skin and respiratory irritation, long-term exposure). It is also corrosive, having a corrosive or bleaching effect on precision instruments, metal surfaces, and fabrics. Long-term use may lead to drug resistance in microorganisms. Some potent disinfectants require professional handling, posing safety hazards during storage and use. Different chemical disinfectants have significantly different killing effects on different pathogens, limited broad-spectrum activity, linear transmission, weak penetration, and blind spots (shadow areas). Prolonged exposure may damage human skin and eyes; air disinfection requires long-term circulation; and it cannot treat internal contaminants on surfaces.

[0003] Traditional plasma-activated liquids are typically activated within a reactor before being sprayed for use. This process can be complex, and the activity of the activated liquid decreases over time. Summary of the Invention

A metering component is slidably connected to the side of the ionization shell. An upper ionization component is fixedly connected to the side of the ionization shell below the metering component, and a lower ionization component is fixedly connected to the side of the ionization shell below the upper ionization component. A recovery tank is connected to the bottom of the ionization shell. A through hole is provided on the side of the ionization shell. The bottom of the recovery tank is fixedly connected to the top of the equipment base plate. The side of the ionization shell communicates with the side of the spraying device through the through hole. The ionization shell ionizes the water... The system includes a storage and inlet connector for water flow introduction, a metering component for quantitative sodium chloride introduction to improve water conductivity, facilitating ionization under high pressure, and an upper ionization component for water ionization through interaction with the ionization component. The design of the corresponding components maintains the ionized state just before the water is ejected, preventing the water flow from reverting to its original state. A recycling tank recovers and reuses the water, homogenizing the ionized water and facilitating uniform mixing. The dissolved sodium chloride further enhances homogenization, making water ionization easier.

[0005] Preferably, the metering component includes a sliding housing, a metering groove is fixedly connected to the bottom of the inner wall of the sliding housing, a limiting hole is formed at the bottom of the metering groove, a handle is fixedly connected to the side of the sliding housing, the sliding housing passes through the side of the ionization housing and is slidably connected to the ionization housing, and the limiting hole is located below the water inlet connector.

[0006] Preferably, the upper ionization assembly includes a rotating rod, a rotating sleeve is sleeved and rotatably connected to the side of the rotating rod, an upper ionization grid is fixedly connected to the bottom of the rotating sleeve, an upper fixed electrode is fixedly connected to the side of the rotating rod, and the upper fixed electrode penetrates the side of the ionization shell and is fixedly connected to the ionization shell.

[0007] Preferably, the lower ionization assembly includes a lower base plate, a discharge electrode fixedly connected to the top of the lower base plate, a discharge ring fixedly connected to the middle of the top of the lower base plate, and a lower fixed electrode fixedly connected to the side of the lower base plate. The lower fixed electrode penetrates the side of the ionization shell and is fixedly connected to the ionization shell. The spraying device extends into the nickel inner wall of the discharge ring and is fixedly connected to the discharge ring. Sodium chloride is placed at the bottom of the inner wall of the metering tank and is limited by a limiting hole. The top of the metering tank corresponds to the bottom of the water inlet connector, which facilitates the dissolution of sodium chloride under the impact of water, prevents sodium chloride from escaping to other parts of the sliding shell, and prevents dead zones that could lead to incomplete dissolution of sodium chloride in the water, thereby affecting the conductivity of the solution. The upper fixed electrode is energized, which conducts electricity to the rotating rod, which in turn conducts electricity to the rotating sleeve, thereby ionizing the water. The rotating sleeve and rotating rod are designed to rotate autonomously under the influence of the water flow introduced through the inlet connector, facilitating ionization at different locations in the water. The lower fixed electrode is powered, and the current flows along the lower fixed electrode into the lower base plate, then into the discharge electrode and discharge ring. Under the action of the upper ionization net, the tip of the discharge electrode discharges through opposite charges, facilitating the ionization of the water. The discharge ring also surrounds the spraying device, specifically maintaining the ionized state of the water flow to be output, thus ensuring the disinfection effect of the ionized water sprayed out.

[0008] Preferably, the spraying device includes an air guide pipe, the top of which is connected to a water inlet pipe, the side of which is connected to a water delivery pipe, an atomizing component rotatably connected to the side of the air guide pipe, the end of the air guide pipe away from the atomizing component being connected to the side of the air supply device, the water delivery pipe being disposed inside the water inlet pipe, the air guide pipe being fixedly connected to the ionization shell through a through hole, and the air guide pipe extending into the interior of the discharge ring and being fixedly connected to the inner wall of the discharge ring.

The rotating housing is rotatably connected to the side of the guide pipe via the rotating ring. Air passes through the gap between the guide pipe and the water supply pipe, thereby driving the ionized water to move along the inner wall of the water inlet pipe. Air and liquid mix inside the rotating housing, and the pneumatic fan blades, under the influence of air and water flow, drive the rotating housing to rotate, thereby driving the rotating housing to rotate, which in turn drives the fixed base to rotate. The rotation of the fixed base drives the guide pipe to rotate, and the rotation of the guide pipe drives the atomizing nozzle to move, thereby mixing and spraying out the ionized water and air. This allows the air to cover a larger disinfection area. The water to be output is ionized by the discharge ring, thus maintaining the ionized state and preserving the disinfection effect after the water is sprayed out.

[0010] Preferably, the air supply device includes an electric fan, a connecting pipe is fixedly connected to the side of the electric fan, a tapered pipe is connected to the end of the connecting pipe away from the electric fan, a filter assembly is fixedly connected to the side of the connecting pipe, the side of the connecting pipe is fixedly connected to the top of the equipment base plate through a bracket, and the side of the tapered pipe is connected to the side of the air guide pipe.

An electric fan drives air through the bottom of the arc-shaped filter plate, thereby causing the arc-shaped filter plate to deform under the action of wind pressure. The arc-shaped filter plate is lowered, thus preventing excessive twisting under the support of the spring plate, and restoring its original shape under the action of the spring plate. Under the combined action of the sealing plate and the connecting plate, dust is collected and limited to prevent accidental dust falling. The cross-section of the connecting pipe is changed through a tapered tube to guide air, thereby increasing the gas pressure and allowing the ionized water to be sprayed out at a higher speed, thereby maintaining the disinfection effect of the ionized water.

[0012] This invention provides a plasma-activated fog disinfection device. It has the following beneficial effects: 1. This plasma-activated fog disinfection device is equipped with an ionization shell that stores water. A water inlet connector introduces water flow, and a metering component introduces a metered amount of sodium chloride into the water to improve its conductivity, facilitating ionization under high pressure. Water ionization occurs through the interaction of the upper and lower ionization components. The design of the corresponding components maintains the ionized state just before water is ejected, preventing the water flow from reverting to its original state. A recovery tank recycles the water flow, ensuring water reuse and homogenization of the ionized water. This facilitates uniform mixing, and the dissolved sodium chloride further enhances homogenization, making water ionization easier.

[0013] 2. This plasma-activated mist disinfection device is equipped with a metering tank. Sodium chloride is placed at the bottom of the inner wall of the metering tank and limited by a limiting hole. The top of the metering tank corresponds to the bottom of the water inlet connector, which facilitates the dissolution of sodium chloride under the impact of water, prevents sodium chloride from escaping to other parts of the sliding shell, and prevents dead zones that could lead to incomplete dissolution of sodium chloride in the water, thus affecting the conductivity of the solution. The upper fixed electrode is energized, which in turn conducts electricity to the rotating rod, which in turn conducts electricity to the rotating sleeve, thereby ionizing the water. The rotating design of the sleeve and rotating rod facilitates autonomous rotation under the action of the water flow introduced by the water inlet connector, thereby facilitating the ionization of different positions of the water body and supplying power to the lower fixed electrode. The current enters the lower base plate along the lower fixed electrode, and then enters the discharge electrode and discharge ring. Under the action of the upper ionization net, the tip of the discharge electrode is discharged through opposite charges, which facilitates the ionization of the water body by the current. Furthermore, the discharge ring wraps around the spraying device, thus specifically maintaining the ionized state of the water flow to be output, thereby maintaining the disinfection effect when the ionized water is sprayed out.

[0014] 3. This plasma-activated mist disinfection device is equipped with an air guide duct. Air passes through the gap between the air guide duct and the water supply pipe, thereby driving the ionized water to move along the inner wall of the water inlet pipe. The air and liquid mix inside the rotating shell. Under the influence of the air and water flow, the rotating shell rotates, which in turn drives the fixed base to rotate. The rotation of the fixed base drives the guide duct to rotate, which in turn drives the atomizing nozzle to move, thereby spraying out the ionized water and air mixture. Under the action of the air, more disinfection area is covered. The water to be output is ionized by the discharge ring, thereby maintaining the ionized state and ensuring the disinfection effect after the water is sprayed out.

[0015] 4. This plasma-activated fog disinfection device is equipped with an electric fan. The electric fan drives air through the bottom of the arc-shaped filter, thereby deforming the arc-shaped filter under the action of wind pressure. The arc-shaped filter is lowered and supported by spring plates to prevent excessive twisting. Under the action of spring plates, it returns to its original shape. In addition, the sealing plate and connecting plate work together to collect and limit dust, preventing dust from falling accidentally. The cross-section of the connecting pipe is changed through a tapered tube to guide air, thereby increasing the gas pressure and allowing the ionized water to be sprayed out at a higher speed, thus maintaining the disinfection effect of the ionized water.

The side of the ionization housing 301 is connected to the side of the spraying device 4 through the through hole 307.

[0022] The ionization shell 301 stores water, the water inlet connector 302 introduces water flow, and the metering component 303 introduces a metered amount of sodium chloride into the water to improve its conductivity, thus facilitating ionization under high pressure. The water is ionized through the interaction of the upper ionization component 304 and the lower ionization component 305. The design of the lower ionization component 305 keeps the water in an ionized state just before it is sprayed out, thus preventing the water flow from returning to its original state. The recycling tank 306 recycles the water flow. While reusing the water, it works with the lower ionization component 305 to homogenize the ionized water, thus facilitating uniform mixing.

[0026] Sodium chloride is placed at the bottom of the inner wall of the metering tank 3032, and is limited by the limiting hole 3033. The top of the metering tank 3032 corresponds to the bottom of the water inlet connector 302, which facilitates the dissolution of sodium chloride under the impact of water, prevents sodium chloride from escaping to other positions of the sliding shell 3031, and prevents dead zones that could lead to incomplete dissolution of sodium chloride in the water, thus affecting the conductivity of the solution. The upper fixed electrode 3044 is energized, which conducts electricity to the rotating rod 3041, which in turn conducts electricity to the rotating sleeve 3042, thereby ionizing the water. The rotating sleeve 3042 and the rotating rod 3041... The rotating design facilitates autonomous rotation under the action of the water flow introduced by the water inlet connector 302, thereby making it easier to ionize different positions of the water body and supply power to the lower fixed electrode 3054. The current enters the lower base plate 3051 along the lower fixed electrode 3054, and then enters the discharge electrode 3052 and the discharge ring 3053. Under the action of the upper ionization net 3043, the tip of the discharge electrode 3052 is discharged through opposite charges, which facilitates the ionization of the water body by the current.

The air and liquid mix inside the rotating housing 4041, and the rotating housing 4041 rotates under the influence of the air and water flow through the pneumatic fan blades 4042.
