[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] Please see Figures 1 to 4 This utility model provides an air purifier with lifting and ultraviolet light disinfection, including a cabinet 1, an ultraviolet light lifting component 2 and a lifting drive mechanism 3.

[0028] The top of the cabinet 1 has a mounting slot 10, within which the ultraviolet light lifting assembly 2 is slidably and vertically mounted. The ultraviolet light lifting assembly 2 includes a lifting housing 21 and an ultraviolet lamp housed within the lifting housing 21. The lifting housing 21 has a light outlet 22 for the ultraviolet light emitted from the lamp to escape.

[0029] The lifting drive mechanism 3 is installed inside the cabinet 1 and is used to drive the ultraviolet light lifting component 2 to move up and down, so that the ultraviolet light lifting component 2 can be stored in the mounting slot 10 or extend upward from the mounting slot 10, thereby hiding or exposing the light hole 22.

[0030] The beneficial effects of this novel air purifier with lifting and ultraviolet light disinfection are as follows:

[0031] 1. Improve disinfection efficiency: The ultraviolet light lifting component 2 is driven by the lifting drive mechanism 3 to extend upward from the mounting slot 10 at the top of the cabinet 1, so that the light outlet 22 on the lifting box 21 is exposed, which can expand the irradiation range of ultraviolet light and increase the contact area with air, thereby effectively improving the air disinfection and purification efficiency.

[0032] II. Optimized storage and protection: When not in use, the ultraviolet light lifting component 2 can be stored in the mounting slot 10, so that the ultraviolet lamp and light emission hole 22 inside the lifting box 21 are hidden and protected. This can effectively prevent dust, impurities and other contaminants from entering the lifting box 21 and polluting the ultraviolet lamp or blocking the light emission hole 22, ensuring the cleanliness of the ultraviolet lamp and the light emission effect, and extending the service life of the equipment.

[0033] 3. Good structural integration: The ultraviolet lamp is integrated into the lifting box 21 and combined with the installation slot 10 of the cabinet 1, so that the ultraviolet disinfection module and the air purifier form an organic whole, which not only ensures the efficient performance of the ultraviolet disinfection function, but also does not affect the simplicity and compactness of the overall structure of the equipment.

[0034] In this embodiment, the lifting housing 21 includes a main body 211 slidably installed in the mounting groove 10 and a cover plate 212 fixed on the main body 211. The outer dimensions of the cover plate 212 are larger than the cross-sectional dimensions of the mounting groove 10, so that the periphery of the cover plate 212 abuts against the top surface of the cabinet 1 to achieve a limiting position.

[0035] In this embodiment, a human body sensor is installed on the lifting box 21. When the ultraviolet lamp is working, it will automatically turn off when it senses someone nearby, and automatically turn on when it senses that the person has left.

[0036] The advantages of using a lifting box 21 with a main body 211 and a cover plate 212 are as follows:

[0037] 1. Improved structural stability: The main body 211 of the lifting box 21 is slidably installed in the mounting groove 10. The outer dimensions of the cover plate 212 are larger than the cross-sectional dimensions of the mounting groove 10. When the ultraviolet light lifting component 2 rises to its maximum height, the periphery of the cover plate 212 can abut against the top surface of the cabinet 1 to form a mechanical limit. This can accurately control the lifting stroke and prevent the ultraviolet light lifting component 2 from being dislodged from the mounting groove 10 due to over-driving of the lifting drive mechanism 3, thereby enhancing the stability and reliability of the lifting structure.

[0038] II. Optimized Sealing and Protection: When the UV lifting assembly 2 is in its retracted state, the cover plate 212 can cover the opening of the mounting slot 10. Utilizing its structural feature of being larger than the cross-sectional size of the mounting slot 10, it forms an effective shield between the top surface of the cabinet 1 and the cover plate 212, further preventing dust, moisture and other debris from entering the lifting box 21 from the gaps in the mounting slot 10. This enhances the protection effect on the UV lamp and the light outlet 22, and extends the service life of the equipment.

[0039] 3. Simplified limit structure: Limiting is achieved by the abutting cooperation between the cover plate 212 and the top surface of the cabinet 1, eliminating the need for additional complex limit sensors or mechanical blocks. While ensuring the limit function, the equipment structure is simplified, production and manufacturing costs are reduced, and component wear during later maintenance is also reduced.

[0040] IV. Enhance overall aesthetics: When the ultraviolet light lifting component 2 is stored, the cover plate 212 can completely cover the installation slot 10, so that the top surface of the cabinet 1 maintains a flat and uniform appearance, avoids the slot opening being exposed and affecting the overall aesthetics of the equipment, and improves the visual quality of the product.

[0041] In this embodiment, the lifting drive mechanism 3 includes a slide rail 31 and an electric push rod 32. The ultraviolet light lifting assembly 2 is slidably mounted on the cabinet 1 at both ends via the slide rail 31. The bottom end of the electric push rod 32 is connected to the inside of the cabinet 1, and the top end is connected to the bottom of the ultraviolet light lifting assembly 2. Preferably, two electric push rods 32 are arranged in parallel.

[0042] The lifting drive mechanism 3, which uses slide rail 31 and electric push rod 32 in combination, has the following advantages:

[0043] I. Improved Lifting Stability: The lifting drive mechanism 3 adopts a structure that combines slide rail 31 and electric push rod 32. The two ends of the ultraviolet light lifting component 2 are slidably installed on the cabinet 1 through the slide rail 31, so that the lifting movement is precisely guided. With the driving force of the electric push rod 32, the shaking or deviation during the lifting process can be effectively reduced, ensuring that the lifting movement of the ultraviolet light lifting component 2 is smooth and stable, and ensuring the stability of equipment operation.

[0044] II. Enhanced drive reliability: The electric push rod 32 provides lifting power, and its driving force output is stable and controllable, which can accurately control the lifting height and speed of the ultraviolet light lifting component 2; preferably, two electric push rods 32 are arranged in parallel, which can make the driving force distribution more balanced, avoid lifting tilt or component damage caused by single point force, and further improve the load capacity of the drive mechanism and the reliability of long-term use.

[0045] 3. Simplified operation and control: The driving method of the electric push rod 32 facilitates automated control. The lifting, starting and stopping of the ultraviolet light lifting component 2 and the stroke adjustment can be realized through a simple circuit control module, reducing the complexity of operation and improving the intelligence and ease of use of the equipment.

[0046] IV. Optimized structural layout: The combined structure of slide rail 31 and electric push rod 32 is compact and easy to arrange reasonably inside cabinet 1. It will not occupy too much internal space of the equipment, which is conducive to the integrated installation of other functional modules of the air purifier and ensures the compactness of the overall structure of the equipment.

[0047] V. Extended Service Life: The sliding fit of the slide rail 31 can reduce frictional loss during lifting and lowering movements. The mature drive technology of the electric push rod 32 has high wear resistance and fatigue resistance. Combined with the balanced force design of the double push rod, it can effectively reduce the wear rate of components, extend the overall service life of the lifting drive mechanism 3, and reduce equipment maintenance costs.

[0048] In this embodiment, a horizontally mounted air guide hood 4 divides the space inside the cabinet 1 into a lower air outlet channel and an upper purification space. Air inlet windows 11 are located at both ends of the cabinet 1. An air outlet window 12, communicating with the air outlet channel, is located on the front side of the cabinet 1. A photo-ionizer 5 is installed on the air guide hood 4 within the purification space. The photo-ionizer 5 utilizes a high-intensity broadband photon wave generator and a photocatalytic medium made of special polymer materials to generate ions, electrons, low-concentration oxygen ions, hydrogen peroxide, hydroxyl radicals, and a large number of negative ions, thereby purifying the air, rapidly and efficiently killing various bacteria in the air, and oxidizing and decomposing chemically toxic and harmful gases in the air. An exhaust vent 40 is located on the air guide hood 4. A fan 6 is installed at the exhaust vent 40, drawing outside air into the purification space inside the cabinet 1 through the air inlet window 11. After being purified by the photo-ionizer 5, the air enters the air outlet channel and is discharged from the exhaust window 12. A filter 7 is installed inside the cabinet 1 at the air inlet window 11.

[0049] The cabinet 1, through the cooperation of the air guide shroud 4, the photoionization purifier 5, the fan 6, and the filter 7, has the following beneficial effects:

[0050] 1. Optimize the air purification path: The interior of the cabinet 1 is divided into a lower air outlet channel and an upper purification space by the air guide hood 4. Combined with the air inlet window 11, the air outlet 40 and the air outlet window 12, an orderly air circulation path is formed. After the air outside the cabinet enters the purification space through the air inlet window 11, it can be fully purified by the photo-hydrogen ion purifier 5. Then, driven by the fan 6, it enters the air outlet channel through the air outlet 40 and is finally discharged from the air outlet window 12. This ensures that the air purification process is continuous and efficient, and improves the overall purification effect.

[0051] II. Enhanced Purification Capacity: A photohydrogen ion purifier 5 is installed on the air guide hood 4 in the purification space. It can generate a variety of purification factors such as ions, electrons, and low-concentration oxygen ions, which can completely kill various bacteria in the air and oxidize and decompose toxic and harmful gases. It works synergistically with the ultraviolet disinfection function of the ultraviolet light lifting component 2 to improve the comprehensiveness and thoroughness of air purification and disinfection from different dimensions.

[0052] 3. Improve air filtration effect: A filter screen 7 is installed in the cabinet 1 at the corresponding air inlet window 11. It can intercept dust, particulate matter and other impurities before the air enters the purification space, avoid large particulate pollutants from affecting the working efficiency and service life of the photohydrogen ion purifier 5, and at the same time reduce the risk of secondary pollution of the purified air and ensure the cleanliness of the output air.

[0053] IV. Improve purification efficiency: The fan 6 actively draws outside air into the cabinet 1 to form forced air circulation, which accelerates the air circulation speed in the purification space and the contact efficiency with the photohydrogen ion purifier 5, shortens the purification cycle, and enables the purified air to be quickly discharged from the air outlet 12 and diffused into the surrounding environment, thereby increasing the amount of air purified per unit time.

[0054] V. Optimized Space Utilization: The horizontal setting of the air guide hood 4 enables the internal space of the cabinet 1 to achieve a layered layout, with the purification space and the air outlet channel each performing their respective functions. This not only provides reasonable installation positions for core components such as the photo-ion purifier 5 and the fan 6, but also ensures the smoothness of the air circulation path. Within the limited cabinet space, it realizes the complete functions of air intake, filtration, purification and exhaust, making the equipment structure more compact and efficient.

[0055] In this embodiment, the cabinet 1 includes a main frame 13, a front side panel 14, a rear door 15, end panels 16, a top panel 17, and a bottom panel. The front side panel 14 and the rear door 15 are respectively installed on the front and rear sides of the main frame 13. Two end panels 16 are respectively installed on the left and right ends of the main frame 13. The top panel 17 and the bottom panel are respectively installed on the top and bottom of the main frame 13. A mounting groove 10 is formed on the top panel 17. An air outlet 12 is formed on the end panel 16. A wall-mounted panel 18 is installed on the main frame 13 outside the rear door 15.

[0056] The front panel 14 of the cabinet 1 is also equipped with a control panel 8, which is electrically connected to the electric push rod 32 and the fan 6, and is used to control the working status of the electric push rod 32 and the fan 6.

[0057] The working principle of this utility model is as follows:

[0058] When the air purifier is started and the ultraviolet disinfection function needs to be activated, the lifting drive mechanism 3 starts working, driving the ultraviolet lifting component 2 to slide upwards and extend from the mounting slot 10 at the top of the cabinet 1. As the ultraviolet lifting component 2 rises, the light emission hole 22 on the lifting housing 21 is gradually exposed. At this time, the ultraviolet lamp inside the lifting housing 21 is activated, and the emitted ultraviolet light shines through the light emission hole 22 into the external space of the cabinet 1, disinfecting and sterilizing the surrounding environment.

[0059] When the ultraviolet disinfection function is not needed or the equipment is shut down, the lifting drive mechanism 3 reverses its direction, causing the ultraviolet lifting assembly 2 to slide downwards and gradually retract into the mounting slot 10 at the top of the cabinet 1. Once the ultraviolet lifting assembly 2 is fully retracted, the light emission port 22 is hidden within the mounting slot 10, and the ultraviolet lamp is turned off. This achieves storage and protection for the ultraviolet lamp and the light emission port 22, while also preventing accidental exposure of ultraviolet light when not in operation.

[0060] Throughout the process, the ultraviolet light lifting component 2 achieves precise lifting and lowering through the lifting drive mechanism 3. By switching between the hidden and exposed states of the light emission hole 22, the ultraviolet disinfection function is enabled and disabled. At the same time, in conjunction with other purification components of the air purifier, it works together to complete the purification of the air.
