Description

Technical Field

[0001] This utility model belongs to the field of air purifier disinfection, and specifically relates to a disinfection device for air purifiers. Background Technology

[0002] Air purifiers have become essential devices for improving indoor air quality, playing a crucial role, especially in combating pollutants such as bacteria, viruses, and formaldehyde. To enhance purification efficiency, most air purifiers integrate disinfection functions. Common disinfection devices include ultraviolet sterilization modules, plasma generators, ozone generators, and photocatalytic components. These devices inactivate microorganisms in the air and on the filter surface through physical or chemical processes.

[0003] However, to ensure the airtightness of the unit, existing air purifiers often design the filter and disinfection device as a nested or integrated structure. When replacing the filter, users need to disassemble multiple layers of clips, screws, or complex outer shell components, making the operation cumbersome. This is especially inconvenient for elderly users or those with limited physical strength. More importantly, the filter will become less efficient due to dust accumulation and aging over a long period of use. In the existing structure, these components are often blocked by the outer filter or the main frame. Disassembly, cleaning, or replacement requires disassembling the filter system, which not only increases the difficulty of operation but may also damage the filter due to frequent disassembly and assembly.

[0004] Therefore, there is an urgent need for a disinfection device for air purifiers that is easy to assemble and disassemble. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, through the provision of a disassembly and assembly mechanism, allows for the removal and cleaning or replacement of a filter (primary filter, activated carbon filter, or HEPA filter) within the air purifier housing. By inserting a finger into the groove on the bottom side of the connecting ring at the lower end of the corresponding filter, and then rotating the connecting ring to the outside of the corresponding lower limit ring, the filter and its lower connecting ring can be separated from the lower limit ring and thus pulled out of the air purifier housing. This disassembly method eliminates the need to disassemble the entire air purifier housing; simply removing the corresponding connecting ring from the lower end of the housing allows for accurate removal of the filter. This makes filter removal within the air purifier housing extremely convenient and quick, while also avoiding damage to other normal filters by eliminating the need to remove them.

[0019] This invention incorporates an air extraction mechanism. When the air purifier is turned on and the control motor is activated, the output shaft rotates, causing the fan blades within the circular frame to rotate. Simultaneously, air is drawn in from the lower end through the air inlet. This allows air from outside the air purifier's outer casing to enter through the air inlet, be purified by a primary filter, activated carbon filter, and HEPA filter, and then disinfected by an ultraviolet sterilization lamp before entering the circular frame and exiting through the exhaust duct at the front. This process circulates and disinfects the air near the air purifier's outer casing. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This specific embodiment is a disinfection device for an air purifier, and its structural schematic diagram is shown below. Figures 1 to 3As shown, the device includes an air purifier housing 1, with air inlets evenly spaced at the outer end of the housing. A top cover 2 is mounted on the upper end of the housing 1. An air extraction mechanism is located inside the top cover 2, comprising a circular frame 301 fixedly connected to the inner side of the top cover 2. A motor 302 is mounted at the upper center of the circular frame 301. A rotating shaft 303 is fixedly connected to the lower end of the output shaft of the motor 302. Fan blades 304 are fixedly connected at even intervals to the outer side of the rotating shaft 303. An air outlet duct 305 is fixedly connected to the left front end of the circular frame 301. A railing 306 is located at the front end of the top cover 2. The front end of the air outlet duct 305 is fixedly connected to the left front end of the inner side of the air purifier housing 1. An exhaust port is located at the front end of the top cover 2 in front of the air outlet duct 305, and the railing 306 is fixed at even intervals to the inside of the exhaust port on the left front end of the top cover 2. By installing a railing 306 inside the exhaust port, floating debris in the outside air can be prevented from accidentally falling into the exhaust port and damaging the air extraction mechanism.

[0030] An air inlet is located at the lower center of the circular frame 301, and the outer side of the fan blade 304 is slidably connected to the inner side of the circular frame 301. When the air purifier is turned on and the control motor 302 is activated, its output shaft rotates, causing the rotating shaft 303 to rotate, which in turn causes the fan blade 304 to rotate within the circular frame 301. Simultaneously, the rotation draws in air from the lower end through the air inlet. This allows air from outside the air purifier housing 1 to enter through the air inlet, be purified by the primary filter 405, activated carbon filter 406, and HEPA filter 407, and then disinfected by the ultraviolet sterilization lamp 409 before entering the circular frame 301 and exiting through the exhaust duct 305 from the front exhaust port, thus circulating and purifying the air near the air purifier housing 1.

[0031] Cooperate Figures 4 to 6As shown, the air purifier housing 1 has an internal disassembly and assembly mechanism, which includes an upper limit ring 401 fixedly connected to the top of the inner side of the air purifier housing 1. The lower end of the upper limit ring 401 is fixedly connected to a connecting rod 402, and the lower end of the connecting rod 402 is fixedly connected to a lower limit ring 403. An air vent is provided at the middle of the upper end of the air purifier housing 1. Four upper limit rings 401 of different diameters are fixedly connected at equal intervals on the upper side of the upper limit ring 401. The lower end of the connecting rod 402 below the innermost upper limit ring 401 on the upper side of the innermost side of the air purifier housing 1 is connected to the upper side of the base plate 404, and the lower ends of the connecting rods 402 below the three upper limit rings 401 at the outer end are connected to three lower limit rings 403 of different diameters. The lower end of the connecting rod 402 is fixedly connected to the base plate 404. A primary filter 405 is provided inside the air purifier housing 1. An activated carbon filter 406 is provided inside the air purifier housing 1 within the primary filter 405. A HEPA filter 407 is provided inside the air purifier housing 1 within the activated carbon filter 406. The two adjacent upper limit rings 401 on the inner side of the air purifier housing 1 are slidably connected to the outer side of the upper end of the primary filter 405, activated carbon filter 406 and HEPA filter 407. The adjacent side of the lower limit ring 403 on the lower end of the air purifier housing 1 and the side of the lower limit ring 403 adjacent to the base plate 404 are slidably connected to the outer side of the primary filter 405, activated carbon filter 406 and HEPA filter 407. Connecting rings 408 are attached to the lower ends of the primary filter 405, activated carbon filter 406, and HEPA filter 407. An ultraviolet sterilization lamp 409 is installed at the upper center of the base plate 404. The lower limiting ring 403 has an internal thread on its inner side, and the connecting ring 408 has an external thread on its outer side. The inner side of the lower limiting ring 403 is threaded to the outer side of the connecting ring 408. A groove is provided on the lower side of the connecting ring 408. Therefore, when a filter among the primary filter 405, activated carbon filter 406, or HEPA filter 407 in the air purifier housing 1 needs to be removed for cleaning or replacement, a finger can be inserted into the groove on the bottom side of the connecting ring 408 at the lower end of the corresponding filter, and then the connecting ring 408 can be rotated to be located outside the corresponding lower limit ring 403. After the connecting ring 408 is separated from the lower limit ring 403, the filter and the lower connecting ring 408 can be pulled out of the air purifier housing 1. This disassembly method does not require disassembling the entire air purifier housing 1. Only the corresponding connecting ring 408 needs to be removed from the lower end of the air purifier housing 1 to accurately remove the corresponding filter. This makes the disassembly of the filters in the air purifier housing 1 very convenient and quick, and avoids damage to other normal filters by not having to remove them.

[0032] Working principle: When performing air sterilization and disinfection, turning on the air purifier activates the control motor 302, which in turn rotates the output shaft, causing the rotating shaft 303 to rotate and the fan blades 304 to rotate within the circular frame 301. Simultaneously, air from the lower end is drawn in through the air inlet. At the same time, air from the outer end of the air purifier housing 1 enters the housing 1 through the air inlet, is purified by the primary filter 405, activated carbon filter 406, and HEPA filter 407, and then disinfected by the ultraviolet sterilization lamp 409 before entering the circular frame 301 and exiting through the exhaust vent at the front end via the air outlet 305. This process circulates and disinfects the air near the air purifier housing 1.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
