Description

Technical Field

[0001] This application belongs to the field of air purification equipment technology, specifically relating to an air purification and disinfection device. Background Technology

[0002] In existing technologies, air purification and disinfection devices play a crucial role in various scenarios such as medical treatment, home life, and office spaces. They can effectively remove harmful microorganisms and pollutants from the air, kill pathogens such as bacteria and viruses, reduce the risk of cross-infection, provide people with a clean and safe breathing environment, and significantly improve health protection levels. However, air purification and disinfection devices currently on the market have some shortcomings in terms of disinfection technology and overall performance.

[0003] In existing technologies, ultraviolet (UV) lamp disinfection is a widely used method. It kills bacteria by destroying the nucleic acids of microorganisms with UV light, offering advantages such as rapid disinfection and ease of operation. However, UV light poses a risk of leakage, and prolonged exposure can damage human skin and mucous membranes, potentially harming eyesight. Furthermore, its disinfection effect is easily affected by obstructions, making it difficult to achieve thorough disinfection. Ozone disinfection, on the other hand, is widely used in enclosed spaces due to its strong diffusion and ability to eliminate blind spots. However, controlling its concentration is difficult; exceeding safety thresholds can strongly irritate the respiratory tract and eyes, causing discomfort, and may also react with airborne substances to produce secondary pollutants, posing safety hazards. In addition, most existing devices suffer from limited functionality, focusing solely on disinfection while having limited effectiveness in purifying pollutants such as formaldehyde and fine particulate matter, failing to meet the comprehensive needs of diverse scenarios. Therefore, to comprehensively improve the disinfection safety, purification comprehensiveness, and operational efficiency of air purification and disinfection devices, and to avoid secondary pollution and human harm, improvements are urgently needed to enhance the user experience and the overall effectiveness of air purification and disinfection.

[0028] Combination Figures 1 to 10 The following description further illustrates the technical solution proposed in this application. This application adopts the following technical solution: an air purification and disinfection device, comprising a body 1, a purification chamber disposed within the body 1, a purification flow channel disposed within the purification chamber, an air inlet and an air outlet disposed at both ends of the purification flow channel and respectively communicating with the outside of the body, and an air supply assembly 2 disposed within the purification chamber. The air supply assembly 2 divides the purification chamber into a disinfection chamber 3 and a filter chamber 4. A filter assembly 5 is disposed within the filter chamber 4. An ultraviolet disinfection assembly 6 is disposed within the disinfection chamber 3. An isolation assembly 7 is disposed on the outer wall of the disinfection chamber 3. A reflective assembly 8 is disposed on the top of the disinfection chamber 3. When airflow from outside the body 1 is transported to the disinfection chamber 3 along the purification flow channel, the ultraviolet disinfection assembly 6 is used to disinfect the airflow within the disinfection chamber 3, the isolation assembly 7 is used to isolate the ultraviolet light emitted by the ultraviolet disinfection assembly 6, and the reflective assembly 8 is used to reflect the ultraviolet light emitted by the ultraviolet disinfection assembly 6 back into the disinfection chamber 3.

[0029] This application provides an air purification and disinfection device, comprising a main body, a purification chamber and a purification flow channel within the main body, an air inlet and an air outlet at both ends of the purification flow channel, and an air supply component within the purification chamber. The air supply component divides the purification chamber into a disinfection chamber and a filtration chamber. A filter component is installed in the filtration chamber, and an ultraviolet (UV) disinfection component is installed in the disinfection chamber. An isolation component is installed on the outer wall of the disinfection chamber, and a reflective component is installed on the top. By incorporating the isolation component, this application effectively isolates the UV light emitted by the UV disinfection component, effectively preventing UV light leakage. The reflective component reflects UV light into the disinfection chamber, improving UV disinfection efficiency and preventing UV light leakage. The combination of the filter component and the UV disinfection component effectively enhances the degree of air purification. This application has the advantages of reasonable structural design, simple operation, safety and reliability, low implementation cost, wide applicability to various indoor scenarios, and ease of promotion and implementation.

[0030] In this embodiment, the isolation component 7 includes an installation groove 70 disposed on the outer wall of the disinfection chamber 3, and a shielding layer 71 adapted to be installed in the installation groove 70. The material of the shielding layer 71 is any one of 304 stainless steel, aluminum, galvanized steel plate, copper, and carbon fiber.

[0031] In actual implementation, the material of the shielding layer 71 is copper.

[0032] In actual implementation, after the air supply components (such as centrifugal fans and axial fans) are started, a negative pressure is formed in the purification channel, and polluted air outside the unit is drawn into the filter chamber through the air inlet. The air supply components also serve as a physical separator between the disinfection chamber and the filter chamber, forcing the airflow to flow sequentially along the air inlet, filter chamber, air supply components, disinfection chamber, and outlet, avoiding airflow short-circuiting or backflow. Polluted air first enters the filter chamber, where it passes through the filter components (HEPA filters, activated carbon filters, etc.) to trap particulate matter (PM2.5, dust, hair), odor molecules, and some microbial carriers, reducing the pollutant load on the subsequent disinfection chamber and preventing the ultraviolet disinfection components from failing due to pollutant blockage. After the pre-filtered air enters the disinfection chamber, the ultraviolet disinfection components emit 254nm ultraviolet light, which destroys the DNA / RNA structure of microorganisms (bacteria, viruses, fungi), achieving sterilization and disinfection. At the same time, the reflective components on the top of the disinfection chamber reflect the ultraviolet light back into the disinfection chamber, effectively covering the dead corners in the channel and ensuring that the microorganisms in the airflow are fully irradiated. The isolation components on the outer wall of the disinfection room utilize the high reflectivity and absorption properties of metal to block ultraviolet light from leaking out of the machine or the filtration chamber, thus preventing damage to human skin and mucous membranes.

[0033] In actual implementation, a flow equalization plate is provided on the side of the disinfection chamber near the air supply component. The flow equalization plate is used to evenly distribute the airflow into the disinfection chamber.

[0034] Furthermore, the flow equalization plate is provided with a plurality of honeycomb-shaped flow equalization holes, and the flow equalization plate is made of ABS plastic.

[0035] In this embodiment, the reflective component 8 includes a reflective sheet 80 disposed on the top of the disinfection chamber 3, a positioning hole 81 disposed on the reflective sheet 80, and a positioning post 82 disposed in the disinfection chamber 3 at the position corresponding to the positioning hole 81. The positioning post 82 can be matched and extended into the positioning hole 81 so that the reflective sheet 80 can be detachably disposed in the disinfection chamber 3.

[0036] In this embodiment, the material of the reflective sheet 80 is selected from any one of silver foil, aluminum foil, titanium alloy, and polytetrafluoroethylene.

[0037] In actual implementation, titanium alloy is selected as the material for the reflector.

[0038] In this embodiment, the reflective sheet 80 includes a substrate 800 and a plurality of reflective units 801 that are spaced apart along the length and width directions of the substrate 800. The longitudinal cross-sectional shape of the reflective unit 801 is triangular, and the substrate 800 and the reflective unit 801 are integrally formed.

[0039] In actual implementation, the pre-set positioning post on the top of the disinfection chamber matches the positioning hole X of the reflector. After the positioning post is inserted into the positioning hole, the reflector is detachably fixed on the top of the disinfection chamber. This ensures the accuracy of the reflector's installation position (avoiding misalignment that could cause the reflection path to deviate) and also counteracts the vibration generated by the air supply assembly during operation through mechanical cooperation, preventing the reflector from loosening or shifting. When the ultraviolet disinfection assembly emits ultraviolet light, some of the light directly illuminates the airflow channel of the disinfection chamber, while the other part of the light, after illuminating the inclined surface of the triangular reflector unit, is reflected in other directions (such as diagonally downwards or laterally), covering the corners of the disinfection chamber that cannot be reached by direct light, ensuring that the airflow passing through the disinfection chamber is irradiated from all directions. The detachable design allows the reflector to be removed at any time, facilitating the cleaning of dust on the surface of the reflector unit or the replacement of aging reflectors, preventing a decrease in disinfection efficiency due to the performance degradation of the reflector assembly, and ensuring the long-term stable operation of the device.

[0040] In actual implementation, a magnetic suction component is provided on the side of the reflector away from the disinfection chamber, and the magnetic suction component is used to detachably place the reflector in the disinfection chamber.

[0041] In this embodiment, the ultraviolet disinfection component 6 includes multiple slots 60 disposed on the inner wall of the disinfection chamber 3, and multiple ultraviolet lamp groups 61 that are matched and engaged in the slots 60. The multiple slots 60 are spaced apart along the height direction of the disinfection chamber 3.

[0042] In this embodiment, the longitudinal section of the slot 60 is semi-circular, and the ultraviolet lamp group 61 includes a first-stage ultraviolet lamp ring 610, a second-stage ultraviolet lamp ring 611, and a third-stage ultraviolet lamp ring 612 that are sequentially engaged in the slot 60 along the height direction of the disinfection chamber 3.

[0043] In this embodiment, the output power of the first-stage UV lamp ring 610 is defined as X, the output power of the second-stage UV lamp ring 611 is defined as Y, and the output power of the third-stage UV lamp ring 612 is defined as Z. X, Y, and Z satisfy the following relationships: 10W≤X≤20W, 35W≤Y≤50W, 55W≤Z≤65W.

[0044] In actual implementation, X is set to 15W, Y to 40W, and Z to 60W.

[0045] In actual implementation, semi-circular slots spaced along the height of the disinfection chamber's inner wall precisely match the shapes of the primary, secondary, and tertiary UV lamp rings. The curved surfaces of the semi-circular slots fit tightly against the lamp ring shells, enabling rapid fixation of the UV lamp assembly without the need for bolts or other additional fasteners. This also prevents the lamp assembly from shifting due to vibrations in the air supply assembly, ensuring stable irradiation. The three-tiered lamp rings are distributed in layers along the height of the disinfection chamber, forming a continuous annular irradiation area. After pretreatment in the filtration chamber, the airflow enters the disinfection chamber along the purification channel. The 254nm UV light emitted by the primary, secondary, and tertiary UV lamp rings radiates towards the center of the channel. The three-layered annular structure covers the entire cross-section of the disinfection chamber from different heights. Combined with the reflective effect of the top reflective component, this effectively eliminates irradiation dead zones within the disinfection chamber.

[0046] In actual implementation, the first, second, and third level UV lamp rings are connected in parallel, and the first, second, and third level UV lamp rings can be started and stopped independently. Users can adjust the starting combination according to the level of indoor pollution: only the first level UV lamp ring is turned on when the pollution is light, the first and second level UV lamp rings are turned on when the pollution is moderate, and all UV lamp rings are turned on when the pollution is heavy, so as to reduce energy consumption while ensuring the disinfection effect.

[0047] In this embodiment, a limiting component 9 is also provided between the air supply component 2, the filter component 5 and the body 1. The limiting component 9 is used to restrict the filter component 5 from moving away from the filter chamber 4.

[0048] In this embodiment, the limiting component 9 includes an upper limiting groove 90 on the side of the air supply component 2 near the filter component 5, a lower limiting groove 91 at the bottom of the purification chamber, and a limiting station 92 formed by the upper limiting groove 90 and the lower limiting groove 91. The filter component 5 is adapted to be installed in the limiting station 92.

[0049] This application provides an air purification and disinfection device, comprising a main body, a purification chamber and a purification flow channel within the main body, an air inlet and an air outlet at both ends of the purification flow channel, and an air supply component within the purification chamber. The air supply component divides the purification chamber into a disinfection chamber and a filtration chamber. A filter component is installed in the filtration chamber, and an ultraviolet (UV) disinfection component is installed in the disinfection chamber. An isolation component is installed on the outer wall of the disinfection chamber, and a reflective component is installed on the top. By incorporating the isolation component, this application effectively isolates the UV light emitted by the UV disinfection component, effectively preventing UV light leakage.
