Description

An air sterilizer structure Technical Field

[0001] This application relates to the field of air disinfection technology, and in particular to an air disinfection device structure. Background Technology

[0002] A related technology, with publication number CN214581633U, describes an air sterilizer comprising an air inlet, a first filter chamber, an air supply chamber, a sterilization chamber, a second filter chamber, and an air outlet, connected in sequence. Both the first and second filter chambers are equipped with filtration structures, with the second filter chamber containing at least two layers of filters. This air sterilizer, by employing at least two filtration structures, particularly with two layers of filters downstream of the sterilization chamber, effectively reduces the amount of residual bacteria in the air exiting the sterilizer while killing pathogens. This improves the sterilization efficiency and purification effect of the air sterilizer, thus protecting the user's health.

[0003] The air purifier structure in the aforementioned technology filters airborne germs using a filter screen. However, traditional filters have several problems with long-term use: First, airborne germs accumulate on the filter screen, increasing over time. This not only reduces the filter's efficiency but can also become a new source of pollution. Second, while the filter screen effectively blocks germs, it cannot completely prevent them from penetrating, thus limiting the disinfection effect. Summary of the Invention

[0004] To address the issues that traditional filters tend to accumulate bacteria and become new sources of pollution during long-term use, and that while filters are effective at blocking bacteria, they cannot completely prevent bacteria from penetrating, thus limiting disinfection effectiveness, this application provides an air sterilizer structure.

[0005] The air sterilizer structure provided in this application adopts the following technical solution: it includes a protective shell, support gaskets disposed at the four corners of the lower end face of the protective shell, a mounting seat disposed in the upper part of the inner cavity of the protective shell, a photocatalyst carrier disposed on the mounting seat, an air guiding mechanism disposed on the outer periphery of the photocatalyst carrier, an air inlet unit disposed on the upper end face of the protective shell, and an exhaust hood disposed in the lower part of the protective shell.

[0006] The air intake unit includes an air collecting hood disposed relative to the air guiding mechanism and connected to the protective housing, and an ultraviolet generating device disposed in the middle of the air collecting hood and disposed relative to the photocatalyst carrier.

[0007] By adopting the above technical solution, and by setting up a protective shell, supporting gaskets, mounting base, photocatalyst carrier, air guiding mechanism, air intake unit, and exhaust hood, a highly efficient air sterilization and purification effect is achieved. The supporting gaskets are placed at the four corners of the lower end face of the protective shell, effectively ensuring the stable installation of the protective shell and providing shock absorption, thus improving the overall safety and stability of use. The photocatalyst carrier is placed on the mounting base and, after being irradiated with ultraviolet light, generates a photocatalytic reaction, effectively killing bacteria and viruses in the air and on object surfaces. The air guiding mechanism is arranged around the photocatalyst carrier, guiding air to flow evenly across the photocatalyst surface, enhancing the sterilization effect. The air intake unit is located on the upper end face of the protective shell, drawing in contaminated air, while the exhaust hood is located in the lower middle part of the protective shell, discharging purified air.

[0008] As a preferred embodiment, the mounting base and the air collector hood are respectively connected to the protective housing via a snap-fit ​​structure, and a sealing gasket is provided at the connection between the mounting base and the air collector hood and the protective housing.

[0009] By adopting the above technical solution, the mounting base and the air collector hood are connected to the protective shell through a snap-fit ​​structure, ensuring stable fixation between each component and preventing loosening due to vibration or external impact during use. Sealing gaskets are installed at the connection points between the mounting base / air collector hood and the protective shell to ensure a tight seal, effectively isolating external interference and maintaining the stability and cleanliness of the internal environment.

[0010] As a preferred embodiment, the cross-section of the air collecting hood is configured as a fan-shaped structure, and the inner wall of the air collecting hood is configured as a smooth arc surface.

[0011] By adopting the above technical solution, the cross-section of the air collecting hood is designed as a fan-shaped structure, and its inner wall is set as a smooth arc surface. This design allows the air to be smoothly guided to the center along the arc surface when it enters the air collecting hood, effectively reducing turbulence and resistance during the flow process and improving the concentration of the air.

[0012] As a preferred embodiment, the air guiding mechanism includes a circular air guide hood connected to the mounting base, an air inlet duct uniformly arranged within the air guide hood, an air inlet on the air collecting hood positioned opposite the air inlet duct, and a miniature fan disposed on the lower end face of the air guide hood, wherein the lower end face of the air inlet abuts against the upper end face of the air inlet duct.

[0013] By adopting the above technical solution, the air inlet is evenly arranged inside the air guide hood, forming a smooth airflow channel; the air inlet is set on the air collecting hood, and its lower end face is in close contact with the upper end face of the air inlet, ensuring that the air can smoothly enter the air guide hood and be guided along the air inlet; the micro fan is set on the lower end face of the air guide hood, and the negative pressure generated when it is working will attract external air to enter through the air inlet and then flow upward along the air inlet; during the air intake process, due to the close cooperation between the air inlet and the air inlet, the air flow is smoother, thereby improving the efficiency and uniformity of the air flow, so that the air can be more smoothly guided to the photocatalyst carrier inside the air guide hood.

[0014] As a preferred embodiment, the ultraviolet generating device includes a lamp post located in the middle of the air collecting hood, ultraviolet lamp beads evenly distributed around the outer periphery of the lamp post, and a reflective panel located on the upper surface of the lamp post. The ultraviolet generating device is achieved by setting the lamp post in the middle of its air collecting hood.

[0015] By adopting the above technical solution, ultraviolet lamp beads are evenly distributed around the outer perimeter of the lamp post, and a reflective panel is installed on the upper surface of the lamp post. The technical effect lies in utilizing the ultraviolet rays emitted by the lamp beads, which are reflected by the reflective panel to enhance the irradiation intensity, thereby efficiently and evenly inducing a photocatalytic reaction between the photocatalyst carriers within the air guiding mechanism. Its working principle is that after the ultraviolet lamp beads installed on the lamp post are turned on, the emitted ultraviolet beams are reflected by the mirror surface of the reflective panel, which not only improves the luminous utilization rate of the lamp beads but also allows the ultraviolet beams to form a more comprehensive and dense coverage within the air collection hood, effectively killing bacteria and viruses in the air.

[0016] As a preferred embodiment, the photocatalyst carrier includes a mounting plate disposed in the middle of the air inlet duct, photocatalyst plates evenly disposed on the upper surface of the mounting plate, and mounting ear plates fixedly disposed on both sides of the mounting plate. The mounting ear plates are connected to the air guide shroud by fixing screws.

[0017] By adopting the above technical solution, it is easy to fix the photocatalyst carrier inside the air guide hood. Several photocatalyst plates are arranged in a fan shape. The photocatalyst plates are evenly fixed in the middle of the air inlet duct by the mounting plate. The fan-shaped layout of the photocatalyst plates increases the contact area between the air and the photocatalyst, while ensuring the uniformity of air flow and improving air purification efficiency. Subsequently, the mounting ears on both sides of the mounting plate are fixed in the air guide hood with fixing screws, which facilitates disassembly and maintenance. When air enters from the air inlet duct, it will flow evenly around the photocatalyst plates. The photocatalytic effect generated by the photocatalyst plates under light conditions can effectively decompose harmful substances in the air, thereby achieving a highly efficient air purification effect.

[0018] As a preferred embodiment, the system further includes a protective cover plate disposed on the outer periphery of the lamp post and on the upper surface of the air collecting cover. The outer diameter of the protective cover plate is larger than the outer diameter of the air collecting cover, and the protective cover plate is configured as a perforated plate or a smooth plate.

[0019] By adopting the above technical solution, a protective cover plate with an outer diameter larger than the air collecting cover and designed as a hollow plate or a smooth plate is set on the outer periphery of the lamp post and on the upper end face of the air collecting cover. This can effectively protect the air inlet on the air collecting cover and prevent external dust and debris from entering. It can also gather and concentrate the light emitted by the ultraviolet lamp beads, so that the photocatalytic carrier can come into more full contact with the ultraviolet light, thereby effectively promoting the occurrence of photocatalytic reaction.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. The photocatalyst carrier is placed on the mounting base and undergoes a photocatalytic reaction after being irradiated with ultraviolet light, effectively killing bacteria and viruses in the air and on object surfaces. An air guide mechanism is arranged around the photocatalyst carrier to guide airflow evenly across the photocatalyst surface, enhancing the sterilization effect. The air inlet unit is located on the upper surface of the protective housing, drawing in contaminated air, while the exhaust hood is located in the lower part of the protective housing, discharging purified air.

[0022] 2. The cross-section of the air collecting hood is designed as a fan-shaped structure, and its inner wall is set as a smooth arc surface. This design allows the air to be smoothly guided to the center along the arc surface when it enters the air collecting hood, effectively reducing turbulence and resistance during the flow process and improving the concentration of the air.

[0023] 3. A protective cover with an outer diameter larger than the air collector cover and designed as a perforated plate or a smooth plate is installed on the outer periphery of the lamp post and on the upper end of the air collector cover. This cover can effectively protect the air inlet on the air collector cover from external dust and debris, and can also gather and concentrate the light emitted by the ultraviolet lamp beads, so that the photocatalytic carrier can come into fuller contact with the ultraviolet light, thereby effectively promoting the occurrence of photocatalytic reaction.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] Referring to Figures 1, 2, 3, 4, and 5, this application discloses an air sterilizer structure. It includes a protective housing 11, support washers located at the four corners of the lower end face of the protective housing 11, a mounting base 20 located in the upper part of the inner cavity of the protective housing 11, a photocatalyst carrier 3 located on the mounting base 20, and an air guiding mechanism 2 located around the photocatalyst carrier 3. The air guiding mechanism 2 includes a circular air guide shroud 21 connected to the mounting base 20, an air inlet duct 211 uniformly arranged within the air guide shroud 21, an air inlet 411 located on an air collecting shroud 41 opposite to the air inlet duct 211, and a miniature fan 22 located on the lower end face of the air guide shroud 21. The lower end face of the air inlet 411 abuts against the upper end face of the air inlet duct 211, and the air inlet duct 211 is uniformly arranged within the air guide shroud. Inside the air guide hood 21, a smooth airflow channel is formed. The air inlet 411 is set on the air collecting hood 41, and its lower end face is in close contact with the upper end face of the air inlet channel 211, ensuring that air can smoothly enter the air guide hood 21 and be guided along the air inlet channel 211. The micro fan 22 is set on the lower end face of the air guide hood 21. When it is working, the negative pressure generated will attract external air to enter through the air inlet 411 and then flow upward along the air inlet channel 211. During the air intake process, due to the close cooperation between the air inlet 411 and the air inlet channel 211, the air flow is smoother, thereby improving the efficiency and uniformity of the air flow, so that the air can be more smoothly guided to the photocatalyst carrier 3 inside the air guide hood 21.

[0032] Referring to Figures 2, 3, and 4, an air inlet unit is disposed on the upper surface of the protective housing 11, and an exhaust hood 111 is disposed in the lower part of the protective housing 11. The air inlet unit includes an air collecting hood 41 disposed relative to the air guiding mechanism 2 and connected to the protective housing 11, and an ultraviolet generating device disposed in the middle of the air collecting hood 41 and relative to the photocatalyst carrier 3. In this utility model, by setting up the protective housing 11, support gaskets, mounting base 20, photocatalyst carrier 3, air guiding mechanism 2, air inlet unit, and exhaust hood 111, a highly efficient air sterilization and purification effect is achieved. The support gaskets are placed at the four corners of the lower surface of the protective housing 11, which can effectively ensure the stable installation of the protective housing 11 and reduce vibration, thereby improving the overall safety and stability of use. The photocatalyst carrier 3 is placed on the mounting base 20 and generates a photocatalytic reaction after being irradiated with ultraviolet light, effectively killing bacteria and viruses in the air and on the surface of objects. The air guiding mechanism 2 is arranged around the photocatalyst carrier 3, guiding the air to flow evenly across the photocatalyst surface, enhancing the sterilization effect. The air intake unit is located on the upper surface of the protective housing 11, drawing in polluted air, while the exhaust hood 111 is located in the lower middle part of the protective housing 11, discharging purified air. The entire process is as follows: air is first drawn in through the air intake unit, then evenly guided to the surface of the photocatalyst carrier 3 by the air guide mechanism 2, where a photocatalytic reaction occurs under ultraviolet irradiation, and finally discharged through the exhaust hood 111, thereby achieving efficient and safe air sterilization and purification.

[0033] Referring to Figures 1 and 2, the mounting base 20 and the air collector hood 41 are connected to the protective housing 11 via a snap-fit ​​structure. Sealing gaskets are provided at the connection points between the mounting base 20 and the air collector hood 41 and the protective housing 11. By connecting the mounting base 20 and the air collector hood 41 to the protective housing 11 via the snap-fit ​​structure, stable fixation of each component is ensured, preventing loosening due to vibration or external impact during use. The sealing gaskets at the connection points of the mounting base 20 and the air collector hood 41 with the protective housing 11 ensure a tight seal, effectively isolating external interference and maintaining the stability and cleanliness of the internal environment.

[0034] Referring to Figure 3, the cross-section of the air collecting hood 41 is set as a fan-shaped structure, and the inner wall of the air collecting hood 41 is set as a smooth arc surface. The cross-section of the air collecting hood 41 is designed as a fan-shaped structure, and its inner wall is set as a smooth arc surface. This design allows the air to be smoothly guided to the center along the arc surface when it enters the air collecting hood 41, which effectively reduces turbulence and resistance during the flow process and improves the concentration of the air.

[0035] Referring to Figures 2 and 4, the ultraviolet (UV) generator includes a lamp post 43 positioned in the center of the air collecting hood 41, UV lamp beads 431 evenly distributed around the outer periphery of the lamp post 43, and a reflective panel 432 mounted on the upper surface of the lamp post 43. The UV generator utilizes the UV light emitted by the UV lamp beads 431, which is reflected by the reflective panel 432 to enhance the irradiation intensity, thereby efficiently and uniformly promoting photocatalytic reactions between the photocatalyst carriers 3 within the air guiding mechanism 2. Its working principle is that after the UV lamp beads 431 installed on the lamp post 43 are turned on, the emitted UV beam is reflected by the reflective panel 432, which not only improves the luminous utilization rate of the lamp beads 431 but also creates a more comprehensive and denser coverage of the UV beam within the air collecting hood 41, effectively killing bacteria and viruses in the air.

[0036] Referring to Figure 5, the photocatalyst carrier 3 includes a mounting plate 31 positioned in the middle of the air inlet duct 211, photocatalyst plates 32 evenly distributed on the upper surface of the mounting plate 31, and mounting ear plates 311 fixedly disposed on both sides of the mounting plate 31. The mounting ear plates 311 are connected to the air guide shroud 21 by fixing screws, facilitating the fixed installation of the photocatalyst carrier 3 inside the air guide shroud 21. Several photocatalyst plates 32 are arranged in a fan shape, and the mounting plate 31 evenly fixes the photocatalyst plates 32 in the middle of the air inlet duct 211. The fan-shaped layout increases the contact area between air and photocatalyst, while ensuring uniform airflow and improving air purification efficiency. Subsequently, the mounting ears 311 on both sides of the mounting plate 31 are fixedly installed inside the air guide cover 21 with fixing screws, which facilitates disassembly and maintenance. When air enters from the air inlet duct 211, it will flow evenly around the photocatalyst plate 32. The photocatalytic effect generated by the photocatalyst plate 32 under light conditions can effectively decompose harmful substances in the air, thereby achieving a highly efficient air purification effect.

[0037] Referring to Figures 4 and 5, the system also includes a protective cover plate 42 disposed on the outer periphery of the lamp post 43 and on the upper surface of the air collecting cover 41. The outer diameter of the protective cover plate 42 is larger than the outer diameter of the air collecting cover 41, and the protective cover plate 42 is designed as a perforated plate or a smooth plate. The protective cover plate 42, which is larger than the outer diameter of the air collecting cover 41 and designed as a perforated plate or a smooth plate, is disposed on the outer periphery of the lamp post 43 and on the upper surface of the air collecting cover 41. This can effectively protect the air inlet 411 on the air collecting cover 41, preventing external dust and debris from entering, and can also gather and concentrate the light emitted by the ultraviolet lamp beads 431, so that the photocatalyst carrier 3 can come into more full contact with the ultraviolet light, thereby effectively promoting the occurrence of the photocatalytic reaction.

[0038] The implementation principle of an air sterilizer structure in this application embodiment is as follows: During use, a micro fan 22 is set on the lower end face of the air guide hood 21. The negative pressure generated by the fan during operation will attract external air to enter through the air inlet 411 and then flow upward along the air inlet channel 211. During the air intake process, due to the close cooperation between the air inlet 411 and the air inlet channel 211, the air flow is smoother, thereby improving the efficiency and uniformity of the air flow. This allows the air to be guided more smoothly to the photocatalytic carrier 3 inside the air guide hood 21. The ultraviolet rays emitted by the ultraviolet lamp beads 431 are reflected by the reflective panel 432 to enhance the irradiation intensity, thereby efficiently and uniformly causing a photocatalytic reaction between the photocatalytic carriers 3 inside the air guide mechanism 2. The exhaust hood 111 is located in the lower part of the protective shell 11 and exhausts the purified air.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
