Abstract
Description
Technical Field
[0001] This utility model relates to the field of air purification technology, specifically to a sterilization module and an air purification device. Background Technology
[0002] Household air purifiers with sterilization functions typically use ultraviolet (UV) light for sterilization. By emitting UV rays of specific wavelengths, they destroy the DNA or RNA structure of bacteria, viruses, and other microorganisms, rendering them unable to reproduce and survive. This method boasts advantages such as high sterilization efficiency and speed. However, UV light poses certain risks to human health. If improper design leads to UV leakage, it can harm the user. Furthermore, in air purifiers, UV light needs to directly irradiate the microorganisms to be effective. If the airflow is too fast or the irradiation angle is poor, the sterilization effect will be significantly reduced. Utility Model Content

[0005] A charged module, which has a charged module airflow inlet and a charged module airflow outlet, is used to kill bacteria in the airflow and ionize dust in the airflow, making the dust charged.
[0006] A sterilization electric field module, which has a sterilization electric field module airflow inlet and a sterilization electric field module airflow outlet, wherein the sterilization electric field module airflow inlet is located on one side of the airflow outlet of the charged module, and the sterilization electric field module is used to generate an electric field to collect charged dust and further kill bacteria;
[0007] A filter module is installed inside the sterilization electric field module.
[0008] The beneficial effects of the above-mentioned sterilization module are as follows:
[0009] The aforementioned sterilization module does not use ultraviolet light, thus completely eliminating the risk of harm to the human body from ultraviolet leakage. It does not rely on high-energy-consuming ultraviolet lamps, reducing energy consumption and making it more environmentally friendly. This invention performs primary sterilization via a charged module, followed by secondary sterilization via a sterilization electric field module, effectively ensuring thorough sterilization. Furthermore, in this embodiment, the dust particles are first ionized by the charged module, making them charged, and then the sterilization electric field module captures the charged dust particles. Because the particles are ionized and charged by the charged module, they are more easily captured by the filtration module, allowing for faster and more complete separation of charged dust particles. The charged dust is effectively collected, improving the filtration efficiency for dust particles.
[0010] In one optional implementation, the bactericidal electric field module includes:
[0011] The first polarization grid corresponds to the airflow outlet of the charging module;

[0013] Both the first and second polarization meshes are conductive mesh structures to allow airflow to pass through and to collect dust.
[0014] The beneficial effects of the above technical solution are as follows: When charged dust passes through the two-layer polarized mesh, it is not only physically adsorbed but also subjected to a strong electric field, further disrupting the cell structure of bacteria and viruses and enhancing the sterilization effect. The charged dust, after being treated by the charging module, undergoes secondary treatment in the sterilization electric field module, ensuring a higher sterilization rate. The double-layer polarized mesh design better disperses dust, reduces the risk of clogging with a single-layer mesh, and extends the service life of the equipment.
[0015] In one optional embodiment, when the filter module is disposed inside the bactericidal electric field module, the filter module is positioned between the second polarization mesh and the first polarization mesh, thereby continuously killing bacteria on the filter module and solving the problem of continuous bacterial growth on the filter module.
[0016] In one optional implementation, both the first polarization mesh and the second polarization mesh are arranged in parallel with the filter module.
[0017] And / or, the thickness of the first polarization mesh and the second polarization mesh is 0.5 mm to 3 mm;
[0018] And / or, the voltage applied to the first polarization grid and the second polarization grid is 6kV to 20kV.

[0023] In one optional embodiment, the first electrode and the second electrode are discharge wires / discharge needles / carbon brushes;
[0024] And / or, the voltage range of the charging module is 6kV to 15kV;
[0025] And / or, the wind speed passing through the charged module is 0.1 m / s to 10 m / s;
[0026] And / or, the through holes are linearly arranged through holes or staggered through holes.

[0028] And / or, the thickness of the filter material inside the filter module is 1μm to 100mm.
[0029] Secondly, this utility model also provides an air purification device, comprising:
[0030] The housing has a through mounting hole on its side;
[0031] At least one of the aforementioned sterilization modules is disposed within a mounting hole.
[0032] The beneficial effects of the aforementioned air purification equipment are as follows: Because the sterilization module is directly installed within the mounting hole, it can rapidly sterilize the incoming air, improving sterilization efficiency. This embodiment can be configured with multiple sterilization modules to further enhance the sterilization effect and ensure purer exhaust air. The sterilization modules are installed through the mounting holes, making disassembly and replacement very convenient. Users can replace or clean the modules themselves as needed, reducing maintenance costs. Different sterilization modules can be combined according to actual needs, such as electric field sterilization and ultraviolet sterilization, improving the adaptability and flexibility of the equipment.
[0033] In one optional embodiment, the sterilization module is provided in two parts, and the charged module and the sterilization electric field module of the two sterilization modules are respectively arranged from the outside to the inside inside the mounting hole of the housing.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0042] During flu season, in crowded indoor environments, and in households with elderly people, children, or patients, the demand for the sterilization function of air purifiers is particularly urgent. At the same time, consumers are also concerned about the durability and stability of the sterilization function, hoping that air purifiers will maintain good sterilization effects during prolonged use.
[0043] Household air purifiers with sterilization functions typically use ultraviolet (UV) light for sterilization. By emitting UV rays of specific wavelengths, they destroy the DNA or RNA structure of bacteria, viruses, and other microorganisms, rendering them unable to reproduce and survive. This method boasts advantages such as high sterilization efficiency and speed. However, UV light poses certain risks to human health. If improper design leads to UV leakage, it can harm the user. Furthermore, in air purifiers, UV light needs to directly irradiate the microorganisms to be effective. If the airflow is too fast or the irradiation angle is poor, the sterilization effect will be significantly reduced.
[0044] Based on this, the present invention provides a sterilization module that performs sterilization once through a charged module and then a second sterilization through a sterilization electric field module, effectively ensuring the thoroughness of sterilization and guaranteeing the cleanliness of the air.
[0045] The specific embodiments of this utility model are described in detail below with reference to the sterilization module of the first aspect of this utility model and the air purification device of the second aspect of this utility model.
[0046] According to an embodiment of the present invention, in a first aspect, a sterilization module is provided, combined with... Figures 1 to 2 As shown, the system includes a charged module 1, a sterilization electric field module, and a filter module 4. The charged module 1 has a charged module airflow inlet and a charged module airflow outlet. The charged module 1 is installed before the filter module 4 and is used to ionize the airflow, thereby killing bacteria in the airflow and ionizing dust particles in the airflow, making the dust particles charged. The sterilization electric field module has a sterilization electric field inlet and a sterilization electric field outlet. The sterilization electric field inlet is located on one side of the charged module airflow outlet. The sterilization electric field module is used to generate an electric field to collect charged dust particles and further kill bacteria. The filter module 4 is located inside the sterilization electric field module and is used to capture and collect particulate matter and bacteria.
[0047] The aforementioned sterilization module does not use ultraviolet light, thus completely eliminating the risk of harm to the human body from ultraviolet leakage. It does not rely on high-energy-consuming ultraviolet lamps, reducing energy consumption and making it more environmentally friendly. In this embodiment, sterilization is performed once by the charging module and then a second sterilization by the sterilization electric field module, effectively ensuring thorough sterilization. Furthermore, in this embodiment, the dust particles are first ionized by the charging module, making them charged, and then the sterilization electric field module captures the charged dust particles. Because the particles are ionized and charged by the charging module, they are more easily captured by the filtration module 4, allowing for faster and more complete separation of charged dust particles. The charged dust is effectively collected, improving the filtration efficiency of dust particles.
[0048] By flexibly configuring the position of the filter module, the air handling process can be optimized according to actual needs, improving the adaptability and performance of the equipment.
[0049] In some embodiments, the bactericidal electric field module includes a first polarized mesh 2 and a second polarized mesh 3. The first polarized mesh 2 corresponds to the airflow outlet of the charged module. A gap exists between the second polarized mesh 3 and the first polarized mesh 2, allowing charged dust to be captured more effectively under the influence of the electric field. The first polarized mesh 2 and the second polarized mesh 3 are connected to different power electrodes, forming a stronger and more uniform electric field, thereby improving the adsorption efficiency of charged dust. Specifically, a positive pressure is applied to the first polarized mesh 2, and a negative pressure is applied to the second polarized mesh 3, creating a high-voltage electric field between them, in which bacteria are killed.
[0050] When charged dust passes through the two-layer polarized mesh, it is not only physically adsorbed but also subjected to a strong electric field, further disrupting the cellular structure of bacteria and viruses and enhancing the sterilization effect. The charged dust, after being treated by the charging module, undergoes secondary treatment in the sterilization electric field module, ensuring a higher sterilization rate. The double-layer polarized mesh design better disperses dust, reduces the risk of clogging with a single-layer mesh, and extends the equipment's lifespan.
[0051] Both the first polarization mesh 2 and the second polarization mesh 3 are conductive mesh structures that allow airflow and dust collection. The conductive mesh structure allows for smooth airflow without significantly increasing air resistance, ensuring the efficient operation of the air purifier. The mesh design also results in a more uniform electric field distribution, avoiding insufficient electric field strength in localized areas and improving the overall purification effect.
[0052] When the filter module 4 is placed between the first polarization mesh 2 and the second polarization mesh 3, it can continuously kill bacteria on the filter module 4 and solve the problem of continuous bacterial growth on the filter module 4.
[0053] In some embodiments, when the filter module 4 is disposed inside the bactericidal electric field module, the filter module 4 is disposed between the second polarization mesh 3 and the first polarization mesh 2.
[0054] In this embodiment, charged dust is first initially adsorbed and sterilized by the first polarization mesh 2. Then, it undergoes further physical filtration through the filter module 4 to remove unadsorbed small particles. Finally, it passes through the second polarization mesh 3 for electric field sterilization and dust collection again, ensuring higher air quality in the exhaust. The presence of the filter module 4 increases the chance of intercepting microorganisms, and combined with electric field sterilization, greatly improves the overall sterilization efficiency. The filter module 4 is located within the electric field area, avoiding the problem of poor sterilization in localized areas. Compared to ultraviolet sterilization, electric field sterilization does not require a high-energy-consuming light source, reducing energy consumption. It does not use ultraviolet light or other harmful chemicals, avoiding harm to humans and the environment.
[0055] In some embodiments, both the first polarized mesh 2 and the second polarized mesh 3 are arranged parallel to the filter module 4. This parallel arrangement of the first polarized mesh 2, the filter module 4, and the second polarized mesh 3 ensures a uniform distribution of the electric field, avoiding insufficient electric field strength in localized areas and improving overall sterilization efficiency. The first polarized mesh 2 and the second polarized mesh 3 can be laid flat or pleated.
[0056] The first polarization mesh 2 and the second polarization mesh 3 are made of materials such as metal and conductive plastic. The thickness of the first polarization mesh 2 and the second polarization mesh 3 is 0.5mm to 3mm. The voltage applied to the first polarization mesh 2 and the second polarization mesh 3 is 6kV to 20kV.
[0057] In some embodiments, the charging module 1 includes a frame, a first electrode, and a second electrode. The frame is a hollow frame, and the side of the frame closest to the charging module 1 is a perforated plate with multiple through holes. The first electrode is arranged along the through holes in the perforated plate. The second electrode is disposed inside the frame, corresponding to the first electrode, and the first and second electrodes are respectively connected to different power supply electrodes.
[0058] In some embodiments, the first and second electrodes are discharge wires / discharge needles / carbon brushes, which are uniformly or non-uniformly arranged and require energization. A high-voltage electric field is formed between the discharge wires / discharge needles / carbon brushes and the orifice plate, ionizing the air and charging the particulate matter. The voltage range of the charging module 1 is 6kV to 15kV. The air velocity through the charging module 1 is 0.1m / s to 10m / s, controlled by positive or negative pressure fans to regulate the airflow and thus the air velocity. The sterilization effect of the charging module 1 is 10% to 99.99%. The through holes are linearly arranged or staggeredly arranged.
[0059] In some embodiments, the filtration efficiency of the filter module 4 is E10 to H14, matching the filtration efficiency of the air purifier. The thickness of the filter media inside the filter module 4 is 1μm to 100mm. The filter media material of the filter module 4 can be PET, glass fiber, filter paper, PTFE membrane, micro-foamed PTFE, etc. The shape of the filter media in the filter module 4 can be flat or pleated. The filter module 4 can be installed by potting, slotting, or welding.
[0060] According to an embodiment of the present invention, in a second aspect, an air purification device is provided, combined with... Figures 1 to 3 As shown, the device includes a housing 5 and at least one sterilization module. A mounting hole 51 is provided through the side of the housing 5. The sterilization module is disposed within the mounting hole 51.
[0061] In this embodiment, since the sterilization module is directly installed within the mounting hole 51, it can quickly sterilize the incoming air, improving sterilization efficiency. This embodiment can be configured with multiple sterilization modules to further enhance the sterilization effect and ensure cleaner exhaust air. The sterilization module is installed through the mounting hole 51, making disassembly and replacement very convenient. Users can replace or clean the modules themselves as needed, reducing maintenance costs. Different sterilization modules can be combined according to actual needs, such as electric field sterilization and ultraviolet sterilization, improving the adaptability and flexibility of the equipment.
[0062] The aforementioned air purification equipment can be applied to air purifiers, etc. The air intake configuration of this equipment includes panel-type side intake and tower-type bottom intake. The filtration efficiency rating of this air purification equipment is H11 to H13, the noise level is 20 to 60 decibels, and the purification capacity is a CADR value of 200 to 1500.
[0063] In some embodiments, two sterilization modules are provided. The charged module 1 and the sterilization electric field module of the two sterilization modules are arranged from the outside to the inside inside the mounting hole 51 of the housing 5, so that the air is processed sequentially through the charged module 1 and the sterilization electric field module. The design of two sterilization modules provides a dual purification and sterilization effect, ensuring that the air is treated twice to remove more pollutants. The air passes through the two sterilization modules sequentially, and each treatment improves the air quality, resulting in cleaner exhaust air.
[0064] In some embodiments, the housing 5 is equipped with sensors for detecting filtration effectiveness. The output of the sensors is connected to the input of the controller. The sensors include a particulate matter sensor and / or a VOC sensor and / or a pressure sensor. The particulate matter sensor detects the concentration of particulate matter in the air to ensure the effectiveness of the filtration module. The VOC sensor detects the VOC content in the air to assess air quality. The pressure sensor monitors the pressure difference before and after the filtration module to determine if the filter is clogged. When the sensors detect substandard air quality or a clogged filtration module, the controller will issue an alarm or prompt the user for maintenance.
[0065] In this embodiment, the sensor can monitor air quality and filtration efficiency in real time, ensuring that the device is always in optimal working condition. The controller can automatically adjust the device's operating parameters, such as wind speed and sterilization intensity, based on sensor data to optimize the purification effect.
[0066] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
