[0010] A mounting frame;

[0011] A filter screen is arranged in the mounting frame and covers the area in the mounting frame;

[0012] A field module comprises:

[0013] An electric appliance box is arranged on one side of the shell in the length direction;

[0014] A power supply assembly is arranged in the electric appliance box;

[0015] A support rod is arranged along the length direction of the shell, and two ends of the support rod are connected with the electric appliance box and the shell respectively;

[0016] A transmitting needle is arranged on the side of the support rod facing the filter module, and the transmitting needle is electrically connected with the power supply assembly;

[0017] The installation frame can be pulled out of the shell through the pull-out opening.

[0018] The current of the power supply assembly releases electrons to the air through the transmitting needle, and the electrons collide with substances in the air to form negative ions and transfer to form negative charges by contacting the filter screen.

[0019] In the technical scheme, the air purification device can effectively filter particulate matters in the air by arranging the filter module and the field module in the shell, and further purify the air by releasing electrons through the transmitting needle to form negative ions. After the negative ions contact the filter screen, negative charges are formed, which enhances the adsorption capacity of the filter screen to particulate matters and improves the air purification efficiency. Meanwhile, when dust accumulates too much on the filter screen, the user can take out the filter module through the pull-out opening and clean or replace the filter screen, which is convenient for the user to operate and improves the user experience.

Under the action of the high-voltage power supply, the tip of the emission needle will generate a strong electric field and simultaneously inject a large amount of electrons into the air. The electrons continuously collide with oxygen, nitrogen, particulate matter and other substances in the surrounding air to charge them, forming negative ions. The charged air then enters the windward surface of the filter screen. The negative charge is immediately transferred to the surface of the filter screen. When the particles in the air flow through the filter screen, they are attracted by the electrostatic force.

[0030] In some embodiments of the present application, the emission needles are spaced apart along the length direction of the support rod.

[0032] In some embodiments of the present application, the support rod is provided in multiple, and the multiple support rods are parallel to each other.

[0033] In the technical scheme, this design not only increases the number of emission needle layouts, but also further optimizes the structural stability of the field module. By increasing the number of support rods, the distribution range of the emission needles is wider and more uniform, and the generation efficiency of negative ions is higher.

[0034] In some embodiments of the present application, the filter screen is arranged in a wave shape along the length or width direction of the housing.

[0071] In some embodiments, the filter module 200 includes a mounting bracket 201 and a filter screen 203, the filter screen 203 is arranged in the mounting bracket 201 and covers the area in the mounting bracket 201. The mounting bracket 201 provides stable support for the filter screen 203, ensures that it remains flat and stable when the airflow passes through, so as to effectively intercept the particulate matter in the air and achieve high-efficiency filtering function.

[0072] In some embodiments, the air purification device further includes a field module 300, the field module 300 includes an electrical box 301, the electrical box 301 is arranged on one side of the shell 100 in the length direction.

[0073] In some embodiments, the air purification device further includes a field support rod 302 and a transmitting needle 304. Among them, the support rod 302 is arranged along the length direction of the shell 100, and the two ends of the support rod 302 are connected with the electrical box 301 and the shell 100 respectively. The transmitting needle 304 is arranged on the side of the support rod 302 facing the filter module 200; the transmitting needle 304 is electrically connected with the power supply assembly.

[0074] Among them, one side of the shell 100 in the width direction is provided with a pull-out opening 101; the mounting bracket 201 can be pulled out from the shell 100 through the pull-out opening 101;

[0075] The current of the power supply assembly releases electrons to the air through the emission needle 304, and the electrons collide with substances in the air to form negative ions and contact the filter screen 203 to form a negative charge.

[0076] Through the above scheme, by arranging the filter module 200 and the field module 300 in the shell 100, the air purification device of the present application can effectively filter particulate matter in the air, and further purify the air by releasing electrons through the emission needle 304 to form negative ions. After the negative ions contact the filter screen 203, a negative charge is formed, which enhances the adsorption capacity of the filter screen 203 for particulate matter and improves the air purification efficiency. At the same time, when too much dust accumulates on the filter screen 203, the user can remove the filter module 200 through the pull-out opening and clean or replace the filter screen 203, which is convenient for the user to operate and improves the user's experience.

[0077] In some embodiments, the shell 100 is a rectangular frame, which can also be understood as a rectangular body formed through in the thickness direction. The shell 100 with this shape has a simple structure and is easy to produce and manufacture. The shell 100 adopts a rectangular frame structure, which provides stable support and reasonable space layout for the entire air purification device. This design not only enables the internal components of the device to be arranged in order, such as the precise installation of the filter module 200 and the field module 300, but also facilitates the user to quickly disassemble and replace the filter screen 203 through the pull-out opening 101.

[0078] In some embodiments, the mounting bracket 201 is a rectangular frame, which can also be understood as a rectangular body formed through in the thickness direction. The mounting bracket 201 is convenient to install inside the shell 100.

[0079] In some embodiments, after the filter module 200 is installed to the shell 100, the two outer walls of the mounting bracket 201 in the length direction are used to fit the corresponding inner side walls of the shell 100 in the length direction.

[0080] In some embodiments, the length and thickness of the pull-out opening 101 correspond to the length and thickness of the mounting bracket 201. In this way, the mounting bracket 201 is inserted into the shell 100 through the pull-out opening 101. This precise size matching not only ensures the stability of the mounting bracket 201 when it is inserted, avoiding shaking or loosening due to too large gaps, but also facilitates the user to quickly complete the replacement or maintenance operation of the filter screen 203, significantly improving the user experience and maintenance efficiency.

[0081] In some embodiments, the filter screen 203 can be detachably arranged in the mounting frame 201. The design allows users to quickly detach the filter screen 203 for cleaning or replacement according to actual use, without the need for complex tools or operation procedures, greatly reducing maintenance costs and time. At the same time, the design of the detachable filter screen 203 also provides users with higher flexibility, allowing them to choose different functional filter screens 203 according to different air pollution conditions, such as special filter screens 203 for particulate matter, odors, or harmful gases, thereby improving air purification efficiency.

[0082] In some embodiments, the filter screen 203 is an electrostatic precipitator screen. The specific material can be an electrostatic precipitator melt-blown non-woven fabric. The electrostatic precipitator melt-blown non-woven fabric is made of polypropylene material with a precipitator heated and mixed by melt-blown. It is charged with static electricity through high-voltage electrostatic precipitator or water precipitator process.

[0083] In some embodiments, the mounting frame 201 can be made of polyethylene terephthalate material.

[0084] In some embodiments, the electrical box 301 can be integrally formed with the housing 100. Integrally forming the electrical box 301 with the housing 100 significantly improves the overall structural stability and sealing of the air purification device. This design eliminates the potential failure risk caused by loose or poorly sealed connection parts in traditional split structures, enhancing the durability and reliability of the device. The integrally formed structure also reduces the number of parts and assembly procedures, lowers production costs and assembly errors, and improves production efficiency.

[0085] In another embodiment, the electrical box 301 can be detachably arranged with the housing 100. This design allows users or maintenance personnel to quickly replace or repair the power supply components in the electrical box 301 without disassembling the entire device, reducing maintenance time and cost. At the same time, the detachable arrangement facilitates the individual upgrading or updating of the electrical box 301 to adapt to different technical requirements or functional expansion, extending the service life of the product.

[0086] In some embodiments, the power supply component can be directly arranged on the housing 100.

[0087] Further, when the electrical box 301 is detachably connected with the housing 100, the specific connection forms include but are not limited to snap connection, screw connection.

[0088] In some embodiments, the power supply component can be a high-voltage power supply. The high-voltage power supply supplies power to the emission needle 304. It can provide stable high voltage for the emission needle 304, enabling it to form a strong electric field at the tip.

[0089] In another embodiment, the power supply component can be a transformer that converts the voltage of an external power supply to high voltage and transmits it to the emission needle 304.

[0090] In some embodiments, the input end of the power supply assembly is respectively connected to the power negative contact, the ground contact and the power positive contact from inside the electrical appliance box 301; the output end of the power supply assembly is connected to the plurality of emitting needles 304 through the high-voltage line.

[0091] In some embodiments, the mounting rack 201 is in the mounted state when it is installed inside the shell 100, and in the mounted state, the mounting rack 201 is provided with a handle 202 at both ends of the side wall close to the pull-out opening 101. By providing the handle 202 at both ends of the side wall close to the pull-out opening 101 of the mounting rack 201, it is convenient for the user to quickly and conveniently pull out or insert the mounting rack 201 from the shell 100, improving the convenience of replacing and maintaining the filter screen 203, and reducing the maintenance time and labor intensity.

[0092] In some embodiments, the handle 202 is provided on both sides of the mounting rack 201 in the width direction close to the side wall of the pull-out opening 101.

[0093] In some embodiments, the handle 202 can also be provided with only one or more. The position of the handle 202 is not fixed.

[0094] In some embodiments, the material of the handle 202 can be cloth, and the handle 202 is annular. Cloth is soft and comfortable, which can reduce the friction and fatigue of the user's hands when pulling out or inserting the mounting rack 201, and its light weight characteristic will not increase the overall weight of the device. The annular design further improves the convenience of use, and the user can easily hook the handle 202 with his fingers to achieve one-handed operation, whether pulling out or pushing back the mounting rack 201 is more flexible.

[0095] In some embodiments, the inner wall of the shell 100 is provided with two parallel gratings 400, and the grating 400 is used to abut against both sides of the mounting rack 201. Through the setting of the grating 400, it ensures that the mounting rack 201 is fixed more firmly in the shell 100, preventing displacement of the mounting rack 201 due to vibration or airflow impact, thereby ensuring the stability and reliability of the filtering effect of the filter screen 203.

[0096] In some embodiments, the two gratings 400 are arranged in parallel in the shell 100, and the pull-out opening 101 is located between the two gratings 400. The parallel gratings 400 can provide stable support and precise guidance for the mounting rack 201, ensuring that it remains stable during the pulling out and inserting process, avoiding damage or insecure installation of the filter screen 203 due to shaking or tilting.

[0097] In some embodiments, the support rod 302 is provided with a groove towards one side of the field electric module 300, and an electric circuit board 303 electrically connected with the power supply assembly is arranged in the groove; the emission needle 304 is arranged on the electric circuit board 303 and electrically connected with the electric circuit board 303. In this way, the layout of the emission needle 304 is more reasonable, and the current transmission is more stable. This design not only improves the reliability of the emission needle 304, but also facilitates maintenance and replacement, and reduces the current loss when the emission needle 304 contacts with air.

[0098] In some embodiments, the emission needle 304 is welded with the electric circuit board 303. The welding connection can ensure the stable and reliable electrical connection between the emission needle 304 and the electric circuit board 303, effectively reduce the contact resistance, and reduce the energy loss in the current transmission process, thereby improving the efficiency of the emission needle 304 in releasing electrons. At the same time, the welding process can provide sufficient mechanical strength, so that the emission needle 304 remains stable under high-voltage electric field, avoids loosening or falling off due to vibration or external force, and ensures long-term stable operation of the device. In addition, the welding connection has high process maturity, which is convenient for mass production and quality control, and further improves the reliability and consistency of the product.

[0099] In some embodiments, the groove is sealed with insulating glue 305 towards one side of the electric circuit board 303 facing the field electric module 300. By arranging the sealing insulating glue 305, the moisture, dust and other impurities in the air can be effectively prevented from entering the inside of the electric circuit board 303. This sealing design significantly improves the moisture-proof and dust-proof performance of the electric circuit board 303, avoids the short circuit or corrosion problem caused by environmental factors, thereby prolonging the service life of the electric circuit board 303.

[0100] In some embodiments, the emission needle 304 is in a cylindrical shape, and the length direction of the emission needle 304 is perpendicular to the filter screen 203. It can also be considered that the length direction of the emission needle 304 is the same as the through direction of the shell 100. The emission needle 304 has simple structure and is convenient to process, can uniformly distribute the electric field, reduce the electric field distortion, thereby more efficiently releasing electrons and generating negative ions. The layout of the emission needle 304 perpendicular to the filter screen 203 enables the negative ions to directly act on the surface of the filter screen 203, enhances the electrostatic adsorption capacity of the filter screen 203, and improves the adsorption efficiency of air particulate matters.

[0101] In some embodiments, the cross-sectional area of the emission needle 304 gradually decreases in the direction towards the field electrode module 300. With the gradually decreasing diameter, the emission needle 304 can form a stronger electric field intensity at the tip, thereby more effectively releasing electrons. The tip of the emission needle 304 under the action of the high-voltage power supply can generate a strong electric field and at the same time inject a large amount of electrons into the air, which continuously collide with oxygen, nitrogen, particulate matter and other substances in the surrounding air to make them charged, forming negative ions. The charged air then enters the windward surface of the filter screen 203. The negative charge is then transferred to the surface of the filter screen 203, and when the particulate matter in the air flows through the filter screen 203, it is attracted under the action of electrostatic force.

[0102] In some embodiments, the emission needle 304 can be cylindrical, with its diameter gradually decreasing in the direction towards the field electrode module 300.

[0103] In some embodiments, multiple emission needles 304 are arranged along the length direction of the support rod 302. This design significantly expands the range of negative ion generation. By uniformly distributing multiple emission needles 304 on the support rod 302, the power supply to the filter screen 203 is more uniform, thereby improving the purification effect of the entire filtration area.

[0104] In some embodiments, the spacing between any two adjacent emission needles 304 is the same.

[0105] In some embodiments, multiple support rods 302 are arranged in parallel. This design not only increases the number of emission needle 304 layouts, but also further optimizes the structural stability of the field electrode module 300. By increasing the number of support rods 302, the distribution range of the emission needles 304 is wider and more uniform, and the generation efficiency of negative ions is higher.

[0106] In some embodiments, the spacing between any two adjacent support rods 302 is the same.

[0107] In some embodiments, multiple emission needles 304 are distributed along the length direction and the width direction of the housing 100. This significantly increases the coverage range of the emission needles 304, making the generation of negative ions more uniform and extensive, and being able to fully act on the entire filter screen 203 area. The uniform distribution in the length and width directions ensures that the air entering from any direction can fully contact and charge with negative ions when passing through the housing 100, thereby being adsorbed by the filter screen 203. This design not only improves the uniformity and consistency of air purification, but also optimizes the air flow path, reduces the purification dead angle, and further improves the overall purification effect of the device. At the same time, the multi-directional distribution of the emission needles 304 layout also provides support for the scalability and flexibility of the device, which can be adjusted and optimized according to different housing 100 sizes and purification needs.

[0108] In some embodiments, the filter screen 203 is arranged in a wavy shape along the length of the shell 100.

[0109] In some embodiments, the filter screen 203 is arranged in a wavy shape along the width of the shell 100.

[0110] The wavy filter screen 203 significantly increases the contact area between the filter screen 203 and the air, improving the cleaning effect.

[0111] In some embodiments, the material of the filter screen 203 is electrostatically charged melt-blown non-woven fabric. The electrostatically charged melt-blown non-woven fabric has a durable static charge on the surface of the fibers during production through the electrostatic charging process, which can efficiently adsorb particulate matter in the air, including fine PM2.5 particles, pollen, dust, etc., thereby achieving a deeper purification effect. The fiber structure of this material is fluffy and has high porosity, which not only provides a large specific surface area to enhance adsorption capacity, but also ensures low air resistance, allowing air to flow smoothly through the filter screen 203, reducing energy consumption and improving purification efficiency. In addition, the electrostatic properties of the electrostatically charged melt-blown non-woven fabric are relatively stable during the service life, even after repeated use and a certain degree of cleaning, it can still maintain good filtration performance, reducing the frequency of replacing the filter screen 203, further improving the economy and practicality of the air purification device.

[0112] In addition, the present application also provides an air purification device, which comprises a shell 100, the shell 100 is arranged through along its thickness direction, and the shell 100 plays a supporting role.

[0113] In some embodiments, the air purification device further comprises a filter module 200, and the filter module 200 is arranged in the shell 100. The filter module 200 is the core component, mainly responsible for removing pollutants in the air. It intercepts particulate matter of different particle sizes, such as dust, pollen, PM2.5, etc., through multiple layers of filter material.

[0114] In some embodiments, the filter module 200 comprises a mounting frame 201 and a filter screen 203, and the filter screen 203 is arranged in the mounting frame 201 and covers the area inside the mounting frame 201. The mounting frame 201 provides stable support for the filter screen 203, ensuring that it remains flat and stable when the air flows through, thereby effectively intercepting particulate matter in the air and achieving high-efficiency filtration function.

[0115] In some embodiments, the air purification device further comprises a field module 300, and the field module 300 comprises an electrical box 301 arranged on one side of the shell 100 in the width direction. The field module 300 further comprises a power supply assembly arranged in the electrical box 301. The electrical box 301 accommodates the power supply assembly.

[0116] In some embodiments, the air purification device further comprises a field support rod 302 and a transmitting needle 304. The support rod 302 is arranged along the width direction of the shell 100, and the two ends of the support rod 302 are respectively connected to the electrical box 301 and the shell 100. The transmitting needle 304 is arranged on the side of the support rod 302 facing the filter module 200, and the transmitting needle 304 is electrically connected to the power supply assembly.

[0117] The shell 100 is provided with a pull-out opening 101 on one side in the length direction, and the mounting bracket 201 can be pulled out from the shell 100 through the pull-out opening 101.

[0118] The current of the power supply assembly releases electrons to the air through the transmitting needle 304, and the electrons collide with the substances in the air to form negative ions and contact the filter screen 203 to form negative charges.

[0119] Through the above scheme, by arranging the filter module 200 and the field module 300 in the shell 100, the air purification device of the present application can effectively filter particulate matters in the air, and release electrons through the transmitting needle 304 to form negative ions, and further purify the air. After the negative ions contact the filter screen 203, negative charges are formed, which enhances the adsorption capacity of the filter screen 203 to particulate matters and improves the air purification efficiency. At the same time, when the dust on the filter screen 203 accumulates too much, the user can take out the filter module 200 through the pull-out opening and clean or replace the filter screen 203, which is convenient for the user to operate and improves the user's experience.

[0120] In some embodiments, the field module 300 can be arranged on the windward side of the filter screen 203. Alternatively, the field module 300 can also be arranged on the leeward side of the filter screen 203.

[0121] In some embodiments, the field module 300 is divided into a high-voltage electrode and a grounding electrode, wherein the high-voltage electrode is located on the windward side of the filter screen 203, and the grounding electrode is located on the leeward side of the filter screen 203. The high-voltage electrode and the grounding electrode form a stable high-voltage electric field, and the electrostatic standing electrode melt-blown filter screen 203 is located inside the electric field. The negative ions generated by the front field are adsorbed onto the electrostatic standing electrode filter screen 203. This standing method can more stably perform electrostatic standing on the filter screen 203 and reduce the interference of the surrounding air duct system on the electrostatic standing system.

[0122] In some embodiments, the field electrode module 300 further comprises a counter electrode made of conductive material, which can be a metal such as stainless steel, tungsten steel, and the like corrosion-resistant material, or a plastic piece added with graphene, carbon fiber, carbon powder and the like conductive substance, which mainly consists of a conductive plate and a ventilation hole, wherein the conductive plate is connected with the grounding electrode. The ventilation hole is in one-to-one correspondence with the emission needle 304 and is concentrically arranged. In this case, a stable high-voltage electric field is formed between the negative high-voltage electric field of the emission needle 304 and the conductive plate. Placing the electrostatic precipitator screen 203 in this high-voltage electric field can charge the electrostatic precipitator screen.

[0123] In some embodiments, the main role of the counter electrode is to form a stable electric field structure between the emission needle 304 and the counter electrode, otherwise the electric field around the emission needle 304 will be unstable due to the static electricity in the air and the electric field of the surrounding air duct.

[0124] In some embodiments, the field electrode module 300 is used to supply power to the filter module 200; specifically, the field electrode module 300 supplies power to the filter screen 203 to make the filter screen 203 have a negative charge.

[0125] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model, and those skilled in the art can change, modify, replace and modify the above-mentioned embodiments within the scope of the utility model.
