Technical Field

[0002] In fields with stringent requirements for air cleanliness and sterility, air disinfection and purification devices have become core equipment for environmental management. Slightly acidic electrolyzed water, due to its residue-free and highly effective sterilization properties, is widely used in the field of air disinfection and purification, and related spray-type air disinfection and purification devices have also been promoted.

[0003] Currently, most existing air disinfection and purification devices adopt a single disinfection or single purification structure. Some devices only have a disinfection module, which achieves disinfection by spraying disinfectant. However, disinfectant components (such as acidic disinfectant droplets) are easily left in the air after disinfection. These residual components can irritate the human respiratory tract and may also corrode the internal components of the equipment, affecting the safety and comfort of use. Utility Model Content

The gas-liquid vortex separator and the airflow filter separator are sequentially installed in the exhaust duct, and the two ends of the airflow filter separator are respectively connected to the gas-liquid vortex separator and the exhaust port.

[0012] In one embodiment, the gas-liquid vortex separator includes a cylinder and an exhaust pipe. The cylinder is provided with a spiral guide section, and the cylinder has an air inlet and a liquid outlet. The air inlet is connected to the exhaust pipe, and the liquid outlet is connected to the outside. The exhaust pipe passes through the cylinder and is connected to the airflow filter separator.

[0013] In one embodiment, the extension direction of the air inlet is tangential to the extension direction of the exhaust pipe; the end of the cylinder near the liquid outlet gradually expands from the end away from the liquid outlet.

[0014] In one embodiment, the slightly acidic spray module includes a slightly acidic storage tank, an electrolyzed water generating component, a plurality of slightly acidic spray heads, and a second water pump.

[0015] In one embodiment, the slightly acidic storage tank is equipped with a second water level sensor and a second inlet solenoid valve. The second water level sensor is electrically connected to the second inlet solenoid valve, and one end of the slightly acidic storage tank is connected to an external pure water pipeline.

[0016] In one embodiment, the slightly acidic storage tank is further provided with an electrolyte concentration sensor and a second drain solenoid valve, wherein the electrolyte concentration sensor is electrically connected to the electrolyzed water generation component and the second drain solenoid valve respectively.

Specifically, the main body introduces air to be purified through an air inlet, which is then transported through an air inlet duct to a slightly acidic spray module located near the air inlet for disinfection and sterilization. The disinfected air then enters a pure water spray duct connected to the slightly acidic spray module. A first water pump delivers pure water from a pure water storage tank to multiple pure water spray heads spaced apart within the pure water spray duct to wash the air, removing disinfection residue and impurities. The washed air then enters a gas-liquid separation module located within an exhaust duct and near the exhaust outlet for gas-liquid separation. Finally, clean and dry air is discharged from the exhaust outlet through the exhaust duct. Through multi-stage progressive purification, a complete process of air disinfection, washing, and gas-liquid separation is achieved, effectively improving the air disinfection and purification effect.

[0037] This utility model proposes an air disinfection and purification device 100.

[0038] Please see Figure 1 , Figure 2 as well as Figure 6 In one embodiment of this utility model, the air disinfection and purification device 100 includes a main body 1, a slightly acidic spray module 2, a pure water spray module 3, and a gas-liquid separation module 4. The main body 1 has an air inlet 11, an air outlet 12, an air inlet pipe 13, and an air outlet pipe 14. The air inlet pipe 13 is connected to the air inlet 11, and the air outlet pipe 14 is connected to the air outlet 12. The slightly acidic spray module 2 is located near the air inlet 11 and is connected to the air inlet pipe 13. The pure water spray module 3 includes pure water. The system includes a storage tank 31, a first water pump 32, and multiple pure water spray heads 33. The pure water spray module 3 is equipped with a pure water spray pipe 3a, and each pure water spray head 33 is spaced apart within the pure water spray pipe 3a. The first water pump 32 is connected to the pure water storage tank 31 and each pure water spray head 33. The pure water spray pipe 3a is connected to the slightly acidic spray module 2. The gas-liquid separation module 4 is installed through the exhaust pipe 14 and is located near the exhaust port 12. The gas-liquid separation module 4 is connected to the pure water spray pipe 3a.

[0039] In this embodiment, the air disinfection and purification device 100 can be applied to medical scenarios, public indoor places, and other scenarios, without limitation. The main body 1 provides structural support and installation foundation for the entire air disinfection and purification device 100, forming an airflow path for the air inlet 11, exhaust outlet 12, air inlet duct 13, and exhaust duct 14, guiding the air to be treated to flow through each functional module in sequence, ensuring the orderly progress of the air disinfection and purification process. It can be understood that the main body 1 is similar to a box, with air inlets 11 and exhaust outlets 12 on opposite sides of the main body 1. Air enters the main body 1 through the air inlet 11, undergoes disinfection and purification through the air inlet duct 13 and exhaust duct 14 within the main body 1, and is finally discharged through the exhaust outlet 12. The air inlet duct 13 can be a straight pipe structure, or it can be a bent type or a multi-segment spliced ​​type, etc., without limitation. The material of the air inlet duct 13 can be stainless steel, engineering plastics, etc., and the pipes are sealed together by flanges, sealing rings, etc. The exhaust duct 14 can be a segmented through-type structure, dividing the duct into a section connecting to the pure water spray module 3, a section with a gas-liquid vortex separator 41, a section with an airflow filter separator 42, and an output section leading to the exhaust port 12. Each section is tightly connected to ensure that air passes through the two-stage separation structure in sequence. The slightly acidic spray module 2 is used for preliminary sterilization and disinfection of the air to be treated, utilizing the slightly acidic spray liquid to fully contact the air and kill bacteria, viruses, and other harmful microorganisms in the air. The slightly acidic spray module 2 can be a top atomizing spray structure, or it can be an upper and lower spray structure or a circumferential ring spray structure, etc., without limitation here. The pure water spray module 3 is used for secondary washing and purification of the air treated by the slightly acidic spray, removing residual slightly acidic droplets, soluble impurities, and fine particulate matter from the air, and neutralizing the acidic components of the air. The pure water storage tank 31 is used to store and provide clean pure water, providing a stable and continuous water source for the spray washing process. The purified water storage tank 31 can be made of corrosion-resistant plastic or stainless steel, and it has a closed structure. One end of the purified water storage tank 31 is configured to connect to an external water source to achieve water supply. The first water pump 32 is used to pump water from the purified water storage tank 31 into the purified water spray pipe 3a, providing pressure to the spray heads so that the water can be smoothly atomized and sprayed out. The type of the first water pump 32 can be a magnetic drive pump, a centrifugal pump, a variable frequency booster pump, etc., which is not limited here. The first water pump 32, the purified water storage tank 31, and each purified water spray head 33 can be connected through pipelines. The purified water spray pipe 3a is used to connect to the slightly acidic spray pipe 2a. Multiple purified water spray heads 33 are staggered and arranged in the purified water spray pipe 3a. In one embodiment, the purified water spray pipe 3a has a reserved interface, and the spray heads can be detached and installed through external or internal threads. In another embodiment, each spray head has a buckle or sealing ring at the tail end, which can be directly inserted into the reserved holes in the purified water spray pipe 3a.The purified water spray head 33 atomizes pressurized water into fine droplets, increasing the contact area with air to wash the air after it has undergone slightly acidic disinfection, removing residual acidic droplets, particulate matter, and odors, thus achieving secondary purification. The purified water spray head 33 can be a cone-shaped atomizing nozzle, a fan-shaped wide-angle nozzle, or a rotary-cutting atomizing nozzle, etc., and is made of an anti-clogging material. The gas-liquid separation module 4 completely separates the droplets carried in the air after spraying from the air. Through its internal structure, it first uses centrifugal force to separate most of the droplets, and then filters out residual tiny droplets, ensuring that the air discharged from the exhaust port 12 is dry, clean, and free of droplets, preventing droplets from corroding pipes or causing secondary pollution, ultimately achieving compliant emissions.

[0040] The air disinfection and purification device 100 provided by this utility model, through the structure of the device body 1, the slightly acidic spray module 2, the pure water spray module 3 and the gas-liquid separation module 4 working together, can solve the problems of incomplete disinfection, residual harmful substances, poor gas-liquid separation effect and insufficient operational stability of traditional air purification devices. Specifically, the main body of the equipment 1 introduces air to be purified through the air inlet 11, and delivers it to the slightly acidic spray module 2 located near the air inlet 11 via the air inlet pipe 13 for disinfection and sterilization. The disinfected air then enters the pure water spray pipe 3a connected to the slightly acidic spray module 2. The first water pump 32 delivers pure water from the pure water storage tank 31 to multiple pure water spray heads 33 spaced apart within the pure water spray pipe 3a to wash the air and remove disinfection residue and impurities. The washed air then enters the gas-liquid separation module 4 located in the exhaust pipe 14 near the exhaust port 12 for gas-liquid separation. Finally, the clean and dry air is discharged from the exhaust port 12 through the exhaust pipe 14. Through multi-stage progressive purification, the complete process of air disinfection, washing, and gas-liquid separation is achieved, effectively improving the air disinfection and purification effect. The air inlet duct 13 and exhaust duct 14 are connected to each functional module in an orderly manner to form a closed and continuous airflow channel, avoiding air leakage and pollution, and ensuring stable directional airflow. The pure water spray module 3 is equipped with a pure water storage tank 31, a first water pump 32 and multiple spaced pure water spray heads 33, which provides stable water supply and uniform spraying, effectively removing disinfection residues and improving the cleanliness and gentleness of the exhaust air. The gas-liquid separation module 4 is set near the exhaust port 12 and connected to the pure water spray duct 3a to effectively separate the liquid droplets carried in the airflow, prevent liquid from leaking out with the exhaust air, ensure that the exhaust air is dry and clean, and protect the subsequent exhaust components.

[0041] In one embodiment of the present invention, a first water level sensor 34, a first water inlet solenoid valve 35 and a first drain solenoid valve 36 are provided inside the pure water storage tank 31. The first water level sensor 34 is electrically connected to the first water inlet solenoid valve 35 and the first drain solenoid valve 36 respectively. One side of the pure water storage tank 31 is configured to connect to an external pure water pipeline.

[0042] In this embodiment, combined with Figure 1 To enhance the intelligence of the purified water spray module 3, a first water level sensor 34 is used to detect the water level in the purified water storage tank 31 in real time and transmit the water level signal to the control terminal, forming a linkage control with the first inlet solenoid valve 35 and the first drain solenoid valve 36. The number of first water level sensors 34 is not limited; it can be one, two, etc. Preferably, two sensors are used, with one sensor located at the top and the other at the bottom of the purified water storage tank 31. When the water level is below the set lower limit, the first water level sensor 34 triggers the first inlet solenoid valve 35 to open, automatically replenishing the tank with purified water from outside. When the water level reaches the set upper limit, the first inlet solenoid valve 35 closes, stopping the water intake. When maintenance or water source replacement is required, the first drain solenoid valve 36 opens, draining the water from the tank. The first water level sensor 34 can be an electronic level sensor, a photoelectric level sensor, an ultrasonic level sensor, etc., and can be installed on the side wall of the purified water storage tank 31 by bolt connection, snap-fit, or other methods. The first inlet solenoid valve 35 can be a direct-acting solenoid valve, a pilot-operated solenoid valve, etc., and is connected to the external pure water pipeline via a threaded seal or a quick-connect seal. The first drain solenoid valve 36 is located at the bottom of the pure water storage tank 31, and can be a direct-acting solenoid valve, a pilot-operated solenoid valve, etc., without limitation here.

[0043] In one embodiment of the present invention, the gas-liquid separation module 4 includes a gas-liquid vortex separator 41 and an airflow filter separator 42 arranged at intervals. The gas-liquid vortex separator 41 and the airflow filter separator 42 are sequentially installed in the exhaust pipe 14. The two ends of the airflow filter separator 42 are respectively connected to the gas-liquid vortex separator 41 and the exhaust port 12.

[0044] In this embodiment, combined with Figure 3 and Figure 4The gas-liquid vortex separator 41 is similar to a cyclone centrifuge. In one embodiment, the gas-liquid vortex separator 41 has spiral guide vanes inside to guide the airflow to rotate along the inner wall, separating droplets by centrifugal force. In another embodiment, the gas-liquid vortex separator 41 is conical and tapered, with the vortex separation structure cylinder 411 gradually tapering in the direction of airflow to increase the airflow rotation speed and enhance the centrifugal separation effect. The gas-liquid filter separator can be in the form of a demister or a wire mesh demister. After the preceding vortex separation, most of the large water droplets have been removed, but a very small number of tiny droplets can still rise with the airflow. In one embodiment, the interior of the gas-liquid filter separator is composed of multiple layers of interwoven metal wire mesh or polymer fiber mesh pads. Tiny droplets collide with the filter mesh, are intercepted, condense into large water droplets, and then drip down.

[0045] In one embodiment of the present invention, the gas-liquid vortex separator 41 includes a cylinder 411 and an exhaust pipe 412. The cylinder 411 has an air inlet and a liquid outlet. A spiral guide is provided inside the cylinder 411. The air inlet is connected to the exhaust pipe 14, and the liquid outlet is connected to the outside. The exhaust pipe 412 passes through the cylinder 411 and is connected to the airflow filter separator 42.

[0046] In this embodiment, combined with Figure 3 and Figure 4It can be understood that the gas-liquid vortex separator 41 can actually be understood as a cyclone separator. The cylinder 411 provides a sealed cavity space for gas-liquid vortex separation, constraining the airflow to form a rotational motion while collecting the separated liquid. The cylinder 411 can have a cylindrical structure, and its material can be stainless steel, engineering plastics, etc. The spiral guide section is used to rotate the airflow passing through the inlet along a fixed trajectory to form a stable cyclone, allowing droplets to be thrown towards the wall more quickly. In one embodiment, continuous spiral blades are arranged along the axial direction of the inner wall of the cylinder 411, causing the airflow to rotate along the blades, thereby achieving a uniform gas-liquid separation effect. In another embodiment, multiple arc-shaped guide vanes are arranged on the inner wall of the cylinder 411, with each arc-shaped guide vane staggered along the circumference of the cylinder 411. In yet another embodiment, spiral grooves are machined on the inner wall of the cylinder 411, causing the airflow to form a swirling flow along the spiral grooves. The above can be configured according to specific needs and are not limited here. The air inlet is used to introduce the air carrying liquid droplets after spraying from the exhaust duct 14 into the cylinder 411 of the gas-liquid vortex separator 41, providing a stable airflow inlet for gas-liquid separation and ensuring that all air to be treated can enter the vortex area. The air inlet can be located on one side wall of the cylinder 411, and a guide vane can also be installed inside the air inlet. The air inlet and the exhaust duct 14 can be connected by a flange seal or a plug seal to ensure airtightness. The liquid outlet is used to discharge the separated liquid from the cylinder 411. The liquid outlet can be located on the bottom wall or side wall of the cylinder 411 away from the air inlet, and automatic liquid discharge is achieved by gravity. A one-way valve can be installed at the liquid outlet to prevent backflow of air. The exhaust pipe 412 passes through the inside of the cylinder 411 and serves as the outlet channel for the dry gas. The exhaust pipe 412 enters from the top of the cylinder 411 and extends into the interior of the cylinder 411, with a sealed connection between the exhaust pipe 412 and the inner wall of the cylinder 411. A transition pipe may be provided between the exhaust pipe 412 and the airflow filter separator 42, and a flange is provided at every two connections to achieve a sealed connection.

[0047] In one embodiment of the present invention, the extension direction of the air inlet 11 is tangential to the extension direction of the exhaust pipe 412; the end of the cylinder 411 near the liquid outlet gradually expands from the end away from the liquid outlet.

[0048] In this embodiment, combined with Figure 3 and Figure 4 To ensure a smooth, turbulent vortex flow for more stable and efficient centrifugal separation, the air inlet 11 is positioned on the side of the cylinder 411, with its extension direction tangential to that of the exhaust pipe 412. This guides the airflow carrying liquid droplets tangentially into the cylinder 411. For better collection of the separated waste liquid, the end of the cylinder 411 closest to the outlet gradually expands from the end furthest from the outlet, allowing the waste liquid to flow down the wall and converge, thus improving drainage smoothness.

[0049] In one embodiment of this utility model, the slightly acidic spray module 2 includes a slightly acidic storage tank 21, an electrolytic water generating component 22, a plurality of slightly acidic spray heads 23, and a second water pump 24. The electrolytic water generating component 22 is connected to the slightly acidic storage tank 21. The slightly acidic spray module 2 forms a slightly acidic spray pipe 2a. Each slightly acidic spray head 23 is arranged alternately in the slightly acidic spray pipe 2a. The second water pump 24 is connected to the slightly acidic storage tank 21 and each slightly acidic spray head 23.

[0050] In this embodiment, combined with Figure 1 , Figure 5 and Figure 6To achieve pretreatment of the entire air disinfection and purification device 100, a slightly acidic storage tank 21 is used to store slightly acidic electrolyte for spray disinfection of the airflow entering the air inlet duct 13. The material of the slightly acidic storage tank 21 can be corrosion-resistant stainless steel or engineering plastics, etc. The top of the slightly acidic storage tank 21 is connected to an electrolyzed water generating component 22, and the bottom is connected to a second water pump 24 to achieve stable liquid supply. The electrolyzed water generating component 22 is used to replenish electrolytes in the slightly acidic storage tank 21, and the electrolyte can be dilute hydrochloric acid, sodium chloride, etc. In one embodiment, the electrolyzed water generating component 22 includes a high-concentration liquid tank and a metering pump. The high-concentration liquid tank is used to store a pre-prepared high-concentration electrolyte solution. The inlet end of the metering pump extends into the bottom of the high-concentration mother liquor tank through a pipeline, and the outlet end is connected to the inside of the slightly acidic storage tank 21 through a pipeline. The type of metering pump here is a corrosion-resistant peristaltic pump. In another embodiment, the water electrolysis generation component 22 includes a mother liquor tank and a corrosion-resistant solenoid valve. The mother liquor tank is installed at a height higher than the liquid level of the slightly acidic storage tank 21, utilizing gravitational potential energy for liquid supply. The corrosion-resistant solenoid valve is installed on the outlet pipe at the bottom of the mother liquor tank. When electrolyte replenishment is required, the control module 6 controls the corrosion-resistant solenoid valve to open for a set duration, allowing the high-concentration mother liquor to drip into the slightly acidic storage tank 21 below under gravity, achieving low-cost automatic replenishment. The slightly acidic spray head 23 is used to atomize the pressurized slightly acidic electrolyte into fine droplets, forming a disinfection mist field within the air duct, ensuring full contact with the air to achieve sterilization, disinfection, and air purification. The type of slightly acidic spray head 23 can be a wide-angle atomizing nozzle, a rotary atomizing nozzle, etc. A slightly acidic spray pipe 2a is used to connect to the air inlet pipe 13. Multiple slightly acidic spray heads 23 are arranged alternately within the slightly acidic spray pipe 2a. Multiple installation interfaces or screw holes can be pre-drilled within the slightly acidic spray pipe 2a to allow connection between the multiple slightly acidic spray heads 23 and the slightly acidic spray pipe 2a. A second water pump 24 is used to pump the slightly acidic electrolyte from the slightly acidic storage tank 21 to each spray head, ensuring sufficient pressure for the spray heads to achieve good atomization and maintain a stable and uniform spray disinfection effect. The type of the second water pump 24 can be a booster pump, magnetic pump, or diaphragm pump, etc., and is not limited here. The second water pump 24 can be connected to the slightly acidic storage tank 21 and each slightly acidic spray head 23 via pipelines.

[0051] In one embodiment of this utility model, a second water level sensor 25 and a second water inlet solenoid valve 26 are provided inside the slightly acidic storage tank 21. The second water level sensor 25 is electrically connected to the second water inlet solenoid valve 26, and one end of the slightly acidic storage tank 21 is connected to an external pure water pipeline.

[0052] In this embodiment, combined with Figure 2To achieve automatic water replenishment for the slightly acidic module, the second water level sensor 25 monitors the liquid level in the slightly acidic storage tank 21 in real time, converting the liquid level signal into an electrical signal to form a closed-loop automatic control with the second water inlet solenoid valve 26. When the detected liquid level is lower than the set value, the second water level sensor 25 outputs a signal to open the second water inlet solenoid valve 26, allowing external water to enter the storage tank and provide raw material water for the water electrolysis generation component 22; when the liquid level reaches the set upper limit, the second water inlet solenoid valve 26 closes, stopping the water intake. The type of the second water level sensor 25 can be an electrode-type water level sensor, a non-contact capacitive water level sensor, a float-type water level sensor, etc. The number of second water level sensors 25 can be one, two, etc., preferably two, respectively installed at the upper and bottom of the slightly acidic storage tank 21. The second water level sensor 25 can be directly inserted into the slightly acidic storage tank 21 or connected to the slightly acidic storage tank 21 by bolts, snap-fit, or other methods. The type of the second inlet solenoid valve 26 is the same as that of the first inlet solenoid valve 35, and will not be elaborated further here. It should be noted that the external pure water pipe here is connected to the same water source as the external pure water pipe in the pure water spray module 3. Only a small amount of electrolyte (such as hydrochloric acid or sodium chloride) is added to the external pure water pipe in the slightly acidic spray module 2, and then electrolyzed through the electrolyte generation component.

[0053] In one embodiment of this utility model, the slightly acidic storage tank 21 is further provided with an electrolyte concentration sensor 27 and a second drain solenoid valve 28. The electrolyte concentration sensor 27 is electrically connected to the water electrolysis generation component 22 and the second drain solenoid valve 28, respectively.

[0054] In this embodiment, combined with Figure 2Since the electrolysis process consumes electrolytes, and in conjunction with the previous embodiment, the slightly acidic spray module 2 automatically replenishes water, diluting the solution concentration. The electrolyte concentration sensor 27 is used to maintain the conductivity and chloride ion concentration of the liquid in the slightly acidic storage tank 21, thereby ensuring that the electrolyzed water generating component 22 can continuously and stably generate slightly acidic electrolyzed water of an effective concentration. The electrolyte concentration sensor 27 detects the effective concentration of the slightly acidic electrolyte in the slightly acidic storage tank 21 in real time and converts the concentration signal into an electrical signal, which is linked with the electrolyzed water generating component 22 and the second drain solenoid valve 28 for linkage control. When the concentration is lower than the set threshold, the sensor controls the electrolyzed water generating component 22 to start or increase its working power to continue electrolysis and increase the concentration. When the concentration reaches the set threshold, the sensor controls the electrolyzed water generating component 22 to stop or reduce its power. When the slightly acidic electrolyte is used for a long time, has an abnormal concentration, or needs to be replaced, the sensor triggers the second drain solenoid valve 28 to open, draining the liquid in the storage tank, ensuring that the slightly acidic electrolyte used for spraying is always in an effective and stable concentration range. Its set threshold, i.e., effective chloride ion concentration, is between 10ppm and 40ppm, and pH value is maintained between 5.0 and 6.5. When the concentration sensor detects that the effective chloride concentration is lower than the set lower limit (e.g., 15ppm), it triggers the operation of the electrolyzer and electrolyte replenishment device; it stops when the upper limit (e.g., 30ppm) is reached. The electrolyte concentration sensor 27 can be an electrochemical concentration sensor, an optical concentration sensor, etc., and can be connected to the slightly acidic storage tank 21 by means of plug-in, snap-fit, bolt connection, etc. The setting method of the second drain solenoid valve 28 can refer to that of the first drain solenoid valve 36, and will not be described in detail here.

[0055] In one embodiment of this utility model, the main body 1 of the equipment further includes an airflow connecting pipe 15, the slightly acidic spray module 2 includes a slightly acidic storage tank 21 and a slightly acidic spray pipe 2a, the pure water spray module 3 includes a pure water storage tank 31 and a pure water spray pipe 3a, and the airflow connecting pipe 15 connects the slightly acidic storage tank 21 and the pure water storage tank 31 respectively.

[0056] In this embodiment, combined with Figure 1 and Figure 2The airflow connecting pipe 15 is used to change the airflow direction. The air to be treated flows from top to bottom in the slightly acidic spray module 2. After passing through the slightly acidic module, the air needs to be guided to the bottom of the pure water spray module 3 via the airflow connecting pipe 15, allowing the air to flow from bottom to top in the pure water module. This forms a long-distance U-shaped or W-shaped internal air duct, increasing the residence time of the air within the main body 1 of the equipment. It should be noted that although the airflow connecting pipe is connected to both the slightly acidic storage tank 21 and the pure water storage tank 31, it only connects the airflow portion above the liquid surface in both tanks and does not come into contact with the internal liquid. The airflow connecting pipe 15 can be made of corrosion-resistant engineering plastics, stainless steel, etc., and can be connected to the two tanks via plug-in seals, threaded connections, or flange seals. The airflow connecting pipe 15 is positioned above the highest liquid level of the two tanks to prevent liquid backflow into the pipe. Furthermore, a permeable liquid-resistant membrane can be installed inside the airflow connecting pipe 15 to ensure that only gas passes through the airflow connecting pipe 15.

[0057] In one embodiment of this utility model, the main body 1 of the device further includes an exhaust module 5 and a control module 6. The exhaust module 5 is located near the exhaust port 12, and the control module 6 is electrically connected to the exhaust module 5, the slightly acidic spray module 2, the pure water spray module 3, and the gas-liquid separation module 4 respectively.

[0058] In this embodiment, combined with Figure 1 The exhaust module 5 provides airflow power, ensuring that the air passing through the slightly acidic spray module 2, the pure water spray module 3, and the gas-liquid separation module 4 is finally discharged from the exhaust port 12. The exhaust module 5 can be a centrifugal fan, axial fan, etc., and is not limited here. The exhaust module 5 is located at the end of the exhaust duct 14 near the exhaust port 12. The control module 6 is used to uniformly control the start / stop, operating parameters, and protection logic of the exhaust module 5, the slightly acidic spray module 2, the pure water spray module 3, and the gas-liquid separation module 4, achieving fully automatic coordinated operation. The control module 6 is integrated on one side of the main body 1 of the equipment. The control module 6 can be in the form of a power supply and control box, and can be connected to each module via shielded wires and waterproof connectors.

[0059] It should be noted that the usage process of the air disinfection and purification device 100 provided by this utility model is as follows: air enters the main body 1 of the device through the air inlet 11, and enters the slightly acidic spray pipe 2a through the air inlet pipe 13; the air is disinfected for the first stage by the slightly acidic module; then it enters the pure water spray pipe 3a through the airflow connecting pipe 15, and the air is purified for the second stage by the pure water spray module 3; then the purified air is separated into gas and liquid by the gas-liquid vortex separator 41, and the air after gas-liquid separation is filtered for the second stage by the airflow filter separator 42, and finally, under the action of the exhaust module 5, it is led to the exhaust port 12 through the exhaust pipe 14, thereby realizing the disinfection and purification operation of the entire air disinfection and purification device 100.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
