Description

Technical Field

[0001] This invention relates to the field of window screen technology, specifically to an air-purifying window screen. Background Technology

[0002] Mosquitoes are a major headache, and window screens are the primary means of mosquito prevention. Window screens can also help filter dust and debris entering the room, providing a comfortable and clean home environment and preventing objects from falling from above.

[0003] During the hot summer months, residents need to use window screens to ensure ventilation and keep out insects when resting at home. However, while ventilating, a lot of airborne dust, suspended particles, harmful gases, viruses, and bacteria also enter the room. Prolonged use of air conditioning can lead to low indoor humidity, which can have adverse effects on health.

[0004] When we need ventilation, we need to open the screen window. However, in cases of poor air quality, harmful substances can enter the room through the screen, affecting our health. Zhejiang University City College has invented an air-purifying screen window (application number CN201510974969.3, announcement date 2017-08-04). This device includes a filter, a water mist device, an electrostatic device, a screen frame, and a wastewater box. The filter includes a front filter and a rear filter, which, together with the screen frame, form an internal space within the screen, creating a high-concentration water mist accumulation area. The beneficial effects of this device are: 1. Using a water-absorbing sponge in conjunction with highly water-conducting acetate fiber strips to provide water to the microporous atomizing plate avoids water loss and prevents water from detaching from the atomizing plate, thus improving atomization stability. 2. The electrostatic electrodes are arranged in a cross-array, effectively reducing the thickness of the electrostatic electrodes, thereby reducing the overall thickness of the air-purifying screen and preventing discharge leakage caused by the electrostatic electrodes being installed too close together. By adjusting the distance between the upper and lower electrodes, the electric field strength between the electrodes can be adjusted according to actual conditions to meet the working conditions of different occasions and areas. However, the device has poor ventilation during operation, the electrostatic device used is easily damaged during operation, resulting in high cost of consumables in the later stages, and the device cannot make appropriate adjustments when facing different air quality, thus failing to meet the working requirements of different scenarios.

[0005] Therefore, the present invention provides an air-purifying window screen that can solve the above problems. Summary of the Invention

[0006] The technical problem to be solved by this invention is that existing window screens cannot purify the circulating air and cannot make corresponding adjustments to meet different needs in different environments.

[0007] This invention provides the following technical solution: an air-purifying window screen, comprising a first window frame, a second window frame, a filter assembly, a cleaning mechanism, a fixing mechanism, and a purification mechanism. The second window frame is snap-fitted onto the first window frame. The filter assembly is fixedly connected to the same side of both the first and second window frames via the fixing mechanism. The first and second window frames work together, and the aperture size of the filter assembly can be adjusted by rotating the second window frame. A cleaning mechanism for cleaning the filter assembly is fixedly installed on the upper and right sides of the first window frame, and a purification mechanism for recycling wastewater is fixedly installed on the lower part of the first window frame.

[0008] The air-purifying screen is characterized in that the first window frame and the second window frame are used in conjunction, and the surfaces of the first window frame and the second window frame are polished with a surface roughness of 2.5-4; the filter component can be made of mesh, and the mesh can be 60 mesh; when the outdoor air quality index (AQI) is below 35, the mesh can be aligned using a magnetic element to make the mesh on the first window frame and the second window frame overlap, so that the mesh count of the mesh is 60, the mesh aperture is maximized, and thus the best ventilation effect is achieved; when the outdoor air quality index (AQI) is between 35 and 100, the mesh size of the mesh can be adjusted by rotating the second window frame, so that the mesh count of the mesh reaches 120 mesh, and the air purification capacity is enhanced; when the outdoor air quality index (AQI) is above 100, the mesh size of the mesh can be adjusted by rotating the second window frame, so that the mesh count of the mesh reaches 240 mesh, and the air purification capacity is further enhanced.

[0009] Regarding the selection of mesh materials, existing mesh materials are generally made of nylon or metal. Nylon mesh has poor mechanical properties, its operating temperature should not exceed 100 degrees Celsius, and its stress performance in hot environments is poor, resulting in irreversible deformation and a short service life after prolonged use. Metal mesh is prone to rust and corrosion, is heavy, and inconvenient to clean. Taking all factors into consideration, it was decided to use PET + 30% glass fiber. PET has excellent physical and mechanical properties over a wide temperature range, with an operating temperature up to 120 degrees Celsius. It has excellent electrical insulation properties, and its electrical properties remain good even at high temperatures and high frequencies. It also has good creep resistance, fatigue resistance, abrasion resistance, and dimensional stability. Glass fiber has the advantages of corrosion resistance, high strength, aging resistance, and good fire resistance. It can automatically filter light to prevent ultraviolet radiation, and the ultraviolet index will decrease by 3-4 points under the filtering effect of PET. The combination of the two materials allows many advantages to coexist, effectively intercepting dust and particulate matter from entering the room.

[0010] During the manufacturing process, antibacterial and deodorizing particles can be added to the mesh. These particles can be nano-sized silica and zinc oxide particles. The diameter of the nano-sized silica particles is generally 40nm to 2um, and the diameter of the nano-sized zinc oxide particles is generally 20nm-80nm. In addition to dust and particulate matter, air pollution also includes some harmful gases such as formaldehyde and carbon monoxide. The nano-sized silica and zinc oxide particles can effectively catalyze the photolysis of organic molecules, significantly improving the carbon monoxide conversion rate and removing formaldehyde. At the same time, the nano-sized silica and zinc oxide particles have good ultraviolet shielding properties and superior antibacterial and bacteriostatic properties, which can give the mesh the functions of sun protection, antibacterial, and deodorization.

[0011] Magnetic elements are provided at corresponding positions on both the screen and the window frame. The magnetic elements can be rubber magnetic strips with a coercivity of 150 Oersted. The rubber magnetic strips can be installed using special rubber resin adhesive. The design of the magnetic elements allows for the separation of the window frame and the screen, facilitating replacement if the components are damaged. During use, the magnetic elements can also be used to align the screen and the window frame, so that the screens on the two window frames overlap.

[0012] Two water storage elements are provided, each with a volume of 200ml. These elements are fixed to the upper right side of the first window frame using M6 bolts, ensuring good fixation and easy disassembly and replacement. The first water storage element contains clean water, used to supply water for cleaning the screen and to store filtered wastewater via a first pumping element for reuse. The liquid in the second water storage element is pumped through a second pumping element and then through a second and third water delivery element to the nozzle. The second pumping element can be a miniature water pump with a 12V-2A motor and a head range of 5m. The second water storage element can be fitted with cleaning agents, such as disinfectants, to reduce the spread of viruses and bacteria, depending on the working environment. The first and second water storage elements can be used together, or either element can be used independently.

[0013] The cleaning mechanism includes a nozzle, a fixed block, a first water storage element, a second water storage element, a first water delivery element, a second water delivery element, and a second pumping element. The fixed block has a polished surface with a surface roughness of 1.2-2.8. Driven by the second pumping element, the liquid in the water storage element is drawn into the nozzle through the second and third water delivery elements. The nozzle operates at a pressure of 0.15-0.25 MPa. The nozzle can be made of 304 stainless steel. The nozzle faces the filter assembly and continuously and stably sprays water mist. The water mist condenses on the filter assembly and slowly wets the entire filter assembly under gravity, keeping the filter assembly moist and clean. Dust and particulate matter attached to the filter assembly are carried away by the water flow. Sulfur dioxide, nitrogen dioxide, and benzene in the air are easily soluble in water, and this water flow can purify these harmful gases when air enters the room.

[0014] The cleaning mechanism, due to the fixed block, allows the nozzle to rotate over a wide range. When the air conditioner is on indoors, the indoor humidity is low. By rotating the nozzle to face the room, the room can be humidified evenly. Air freshener can also be added to the second water storage element to freshen the air.

[0015] The purification mechanism includes a groove, a purification module, a first pumping element, and a third water supply element. The groove adopts an arc-shaped structure with a radius of 4-6 mm to facilitate wastewater collection. When the cleaning mechanism is working, water flows down the filter component due to gravity, and after passing through the arc-shaped groove, it all flows into the purification module. The purification module contains many materials for purifying wastewater. Under the purification effect of the purification module, the wastewater can be reused and continued to be supplied to the cleaning mechanism.

[0016] For ease of installation and use, the fixing mechanism is secured by mounting elements on both sides of the first window frame. Existing screens are generally assembled using pulleys or tracks, which are extremely inconvenient to install and disassemble. They are also prone to dust accumulation when not in use for extended periods, and the pulleys and tracks are prone to jamming. The mounting elements can be snap-fit, which allows for quick installation and disassembly of the window frame and provides high stability during use.

[0017] The purification module, specifically the first pumping element, has parameters similar to those of the second pumping element mentioned above. After purifying the wastewater, the recycled water, driven by the first pumping element, is fed into the first water storage element for reuse. This eliminates the need for frequent water replenishment, making the cleaning mechanism convenient and preventing water waste.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention allows for adjustment of the filter assembly's pore size by rotating the second window frame, enabling different adjustments to suit varying air quality and meet daily usage needs. The cleaning mechanism keeps the filter assembly moist and clean for extended periods and, in conjunction with the purification mechanism, recycles wastewater, further ensuring fresh indoor air. When the air conditioner is on, the cleaning device rotates via a fixed block to spray water mist into the room for humidification, solving the problem of indoor dryness when the air conditioner is running. The design of the installation components allows for quick and easy installation and disassembly to accommodate different windows, making it convenient to use.

[0020] 2. This invention features two window frames, allowing for easy adjustment of the filter component's pore size with just a slight adjustment; it offers different options for different air conditions; when air quality is good, it increases the screen's breathability, allowing fresh air to enter the room for rapid ventilation; when outdoor air quality is poor, it further enhances air purification capabilities.

[0021] 3. This invention incorporates a cleaning mechanism that sprays water mist during ventilation, keeping the filter components clean and moist. On one hand, this can promptly remove deposits from the mesh, preventing clogging of the filter components and affecting air purification. On the other hand, some harmful gases in the air are easily soluble in water, and this method can purify some of these harmful gases. When the air conditioner is on indoors, the cleaning mechanism can spray water mist to maintain indoor humidity, preventing indoor occupants from experiencing a decrease in immunity due to dryness and an increased probability of respiratory infections.

[0022] 4. The present invention sets up a purification mechanism to treat and recycle wastewater. The purification mechanism can filter and recycle wastewater, which greatly avoids waste, protects the environment, and achieves the goal of green energy saving. Attached Figure Description

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0037] First Implementation Method

[0038] like Figures 1 to 11 As shown, the device includes a first window frame 1, a second window frame 2, a filter assembly 3, a cleaning mechanism 4, a fixing mechanism 5, and a purification mechanism 6. The second window frame 2 is snap-fitted into the first window frame 1. The filter assembly 3 is fixedly connected to the same side of both the first and second window frames 1 and 2 via the fixing mechanism 5. The first and second window frames 1 work together, and the aperture size of the filter assembly 3 can be adjusted by rotating the second window frame 2. The cleaning mechanism 4 for cleaning the filter assembly 3 is fixedly installed on the upper and right sides of the first window frame 1, and the purification mechanism 6 for recycling wastewater is fixedly installed on the lower part of the first window frame 1.

[0039] like Figure 2As shown, the mesh material is made of PET with 30% glass fiber. Traditional window screens are generally made of nylon or metal. Nylon has poor mechanical properties and is prone to irreversible deformation under external force. It is also prone to oxidation and has a relatively short lifespan, typically requiring replacement after 3-5 years. Metal mesh is often heavy and has poor ventilation. The gaps in metal mesh easily trap dirt, making cleaning difficult. Metal also has poor light transmittance and is prone to rusting over time. PET is a common polymer in daily life, and it has a wide operating temperature range. It possesses excellent physical and mechanical properties, with an operating temperature up to 120℃ and excellent electrical insulation. Even at high temperatures and high frequencies, it exhibits good creep resistance, fatigue resistance, abrasion resistance, and dimensional stability. Fiberglass has advantages such as corrosion resistance, high strength, aging resistance, and good fire resistance, while also automatically filtering light to prevent ultraviolet radiation. By using a blend of PET and 30% fiberglass, the mesh has good mechanical properties and is durable. At the same time, it has good breathability and light transmission, without affecting lighting and ventilation. It is highly adaptable and tolerant of different working environments, effectively intercepting dust and particulate matter from entering the room for a long time.

[0040] like Figure 2 As shown, nano-sized silica and zinc oxide particles can be added during the manufacturing process of the mesh. Nano-sized silica has optical properties that resist ultraviolet rays and can improve the anti-aging, strength, and chemical resistance of other materials. Nano-sized zinc oxide has extremely high chemical activity and excellent catalytic and photocatalytic activity, and also has anti-ultraviolet radiation and bactericidal functions. The combination of the two can significantly improve the carbon monoxide conversion rate and remove formaldehyde. At the same time, the superior antibacterial and bacteriostatic properties of nano-sized silica and zinc oxide particles can also give the mesh the functions of sun protection, antibacterial, and deodorization.

[0041] like Figure 4 and Figure 5 As shown, magnetic elements 51 are provided at corresponding positions on both the screen and the window screen. The magnetic elements 51 can be rubber magnetic strips. The main material components of the rubber magnetic strips are 85% to 92% barium (strontium) ferrite magnetic powder and 5% to 9% CPE. The rubber magnetic strips have moderate magnetic force, can be bent and quickly return to their original shape, are lightweight, easy to install, and low in cost. The window screen and the screen are connected by the rubber magnetic strips, which can achieve quick positioning and installation. This allows for quick and convenient alignment of the screens on window frame 1 and window frame 2 when better ventilation is needed. Furthermore, the installation and removal of the rubber magnetic strips are very convenient when the screen needs to be cleaned and replaced.

[0042] like Figure 6As shown, there are two water storage elements. Water storage element 43 can hold clean water. Water from water storage element 43 can be pumped through water pumping element 48 and then through water conveying element 47 to the cleaning mechanism 4 for water supply. Water filtered by purification module 62 is pumped through water pumping element 63 and then through water conveying element 45 to water storage element 43, enabling multiple uses of wastewater. Water storage element 44 can be filled with appropriate liquids according to the working environment or needs, such as bactericides to reduce the spread of viruses and bacteria. Water from water storage element 44, under the action of water pumping element 48, is fed into water conveying element 45 through water conveying element 46, and together with the water from water storage element 43, is fed into water conveying element 47. Water storage element 43 and water storage element 44 can be used together, or both water storage elements can be used independently.

[0043] like Figure 6 As shown, the cleaning mechanism 4 includes a nozzle 41, a fixing block 42, a first water storage element 43, a second water storage element 44, a first water conveying element 45, a second water conveying element 46, and a second water pumping element 48. Driven by the second water pumping element 43, water from the first and second water storage elements 43 and 44 is pumped into the third water conveying element 47. If the nozzle 41 is directed towards the screen, it will continuously and stably spray water mist. The water mist will condense on the screen and slowly wet the entire screen under gravity, keeping the screen moist and clean. Dust and particulate matter attached to the screen will be carried away by the water, ensuring the screen remains clean and moist for a long time. At the same time, harmful substances in the air, such as sulfur dioxide, nitrogen dioxide, and benzene, are easily soluble in water. When air passes through the screen, these harmful substances will dissolve in the water, thus effectively purifying the air.

[0044] like Figure 7 As shown, the cleaning mechanism 4, with its fixed block 42, allows the nozzle 41 to rotate over a wide range. When air conditioning is needed, the indoor humidity is relatively low. If the room remains dry for a long time, people may experience symptoms such as dry throat, sore throat, dry and painful nasal passages, and dry and itchy skin. By rotating the nozzle 41, the cleaning mechanism 4 can evenly humidify the room, effectively preventing dry air and protecting the health of people. When there is an odor in the room, air freshener can be added to the second water storage element 44 to freshen the air, or a bactericide can be added to disinfect and keep the room clean.

[0045] like Figure 8As shown, the purification mechanism 6 includes a groove 61, a purification module 62, a first pumping element 63, and a fourth water conveying element 64. The groove 61 is arc-shaped, which facilitates the collection of wastewater. When the cleaning mechanism 4 is working, the water mist sprayed by the nozzle 41 wets the mesh, and the water on the mesh flows into the groove 61 under the action of gravity. After passing through the arc-shaped groove 61, it falls into the purification module 62. The purification module 62 mainly includes quartz sand, gravel, anthracite, pebbles, manganese sand, magnetite filter media, and granular activated carbon. These substances can effectively filter out impurities and harmful substances in the water. The filtered water is fed into the first water storage element 43 by the first water conveying element 45 under the action of the first pumping element 63 for reuse.

[0046] like Figure 11 As shown, the fixing mechanism 5 is equipped with mounting elements 52 on both sides of the first window frame 1 for easy installation and use. The mounting elements 52 can be fastened with snaps. Given that existing screens are generally assembled with pulleys or tracks, installation and disassembly are extremely inconvenient, dust easily accumulates after long periods of non-use, and pulleys and tracks are prone to jamming. The design of the mounting elements 52 allows for quick installation and disassembly of the screen, and provides high stability during use. By fixing with the mounting elements 52, the first window frame 1 can be easily installed on existing windows without the need for specific window types, thereby greatly reducing usage costs, avoiding waste, and enhancing the applicability of the invention.

[0047] Second Implementation Method

[0048] like Figure 11 As shown, in the second embodiment of the mounting element 52, the other parts of this embodiment are basically similar to the other structures and installation, locking, engagement, and removal methods in the first embodiment, and will not be repeated here. Only the differences from the first embodiment will be described. The difference is that the mounting element 52 can use bolts. Bolt installation offers greater stability, lower requirements for usage conditions, and greater versatility in the usage environment. However, bolt installation requires more components, which may affect the fixed installation position, and is less convenient than snap-fit ​​installation. Either type of mounting element 52 can be selected as needed.

[0049] During operation, the staff fixes the air-purifying screen to the window where it is needed using the mounting element 52. The filter assembly 3 is aligned with window frame 1 and window frame 2 using the magnetic element 51. Under magnetic attraction, the screen is fixed in window frame 1 and window frame 2. If the outdoor air quality is good, the screens on window frame 1 and window frame 2 can be overlapped to obtain the largest mesh size and achieve the best ventilation effect. When the outdoor air quality is poor, window frame 2 is slightly rotated to minimize the mesh size and achieve the best air purification effect. Water in water storage element 43 is supplied to cleaning mechanism 4 through water delivery element 47 by water pumping element 48, regulating the water flow. The nozzle 41 in the cleaning mechanism 4 is aimed at the screen to spray water mist; the water mist condenses on the filter assembly 3, thus wetting the filter assembly 3 and keeping it clean and moist for a long time; under the action of gravity, the water will flow down the filter assembly 3, carrying away the dust and particulate matter on the filter assembly 3, and the filter assembly 3 is in a moist state, which can absorb harmful substances in the air; the wastewater flows to the bottom of the filter assembly 3, passes through the arc groove 61, and flows into the purification module 62 for filtration; the filtered water is driven by the first water pump element 63 and enters the first water storage element 43 through the first water delivery element 45; when the air conditioner needs to be turned on, the nozzle 41 can be pointed towards the indoor side to spray water mist to humidify the air and prevent the indoor air from becoming dry.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
