Its most important function is to remove dust particles, microorganisms and harmful gases in the air that pose a threat to human health. Activated carbon adsorption air purifiers are a common type of air purifiers on the current market. Through the strong adsorption and purification function of activated carbon, it can effectively remove a variety of harmful substances in the indoor air, optimize the indoor air environment, and create a fresh and healthy living environment.

[0003] For example, Chinese patent publication number CN202078836U discloses an indoor air purifier, which belongs to the field of environmental protection equipment. Its structure includes a bracket and an activated carbon plate. The back of the bracket with an "L"-shaped cross-section is provided with a fixed adhesive, and a plurality of mutually parallel positioning slots are provided on the bottom surface of the bracket. The activated carbon plate is plugged together with the positioning slots to absorb harmful gases in the air and achieve the effect of purifying the air.

[0004] For example, Chinese patent publication number CN220707643U discloses an indoor air purifier, which includes a main body and a mounting plate fixedly connected to the outer walls at both ends of the main body, a plurality of through holes equidistantly distributed are provided between the outer walls at both ends of the mounting plate, and mounting grooves are provided on the outer walls at both ends of the bottom of the main body, and air inlet holes are provided on the inner walls at one end of the mounting grooves, an air inlet net is fixedly connected to the circumferential inner walls of the air inlet holes, and an air inlet pump is fixedly connected to the circumferential inner walls of the air inlet holes; an air outlet structure for exhausting air is provided on the top outer wall of the main body, and a movable frame is provided between the inner walls around the mounting groove, and activated carbon plates are fixedly connected between the inner walls around the movable frame.

The larger activated carbon plate as a whole is divided into a plurality of small activated carbon plates 13, and the air is purified by switching and transferring the plurality of small activated carbon plates 13 one by one. Since the smaller flow aperture of the air inlet end 5 is facing the small activated carbon plate 13, the air can be more evenly distributed on each small activated carbon plate 13 for purification, so that the overall purification load of the small activated carbon plate 13 is more balanced, and the uneven purification phenomenon caused by excessive local purification load is greatly reduced. When a small activated carbon plate 13 reaches saturation, it can be quickly switched to another new small activated carbon plate 13 for purification, thereby ensuring the continuity and efficiency of air purification and fully improving the utilization of the small activated carbon plate 13.

[0069] Further as Figure 4 , Figure 5 and Fig. 9 As shown, it is worth specifically explaining that an inner plate 107 located at the top of the inner frame 101 is fixed on the inner side wall of the shell 4, the bottom surface of the inner plate 107 is fitted with the top surface of the inner frame 101, and a flow port 108 communicating with one of the cavities 104 is provided on the side of the inner plate 107, and an end plate 9 is fixed on the top of the shell 4, and an air outlet 20 communicating with the flow port 108 is provided on the top of the end plate 9; when one of the small activated carbon plates 13 rotates to the air inlet end 5, the small activated carbon plate 1 The corresponding cavity 104 rotates to the flow opening 108 and the cavity 104 and the flow opening 108 overlap, so that the air purified by the small activated carbon board 13 can be discharged into the indoor environment through the cavity 104, the flow opening 108 and the air outlet 20, and the other cavities 104 are sealed by the built-in plate 107 to prevent the air from diffusing to other small activated carbon boards 13, thereby temporarily sealing other small activated carbon boards 13 and ensuring the effect of purifying the air one by one by multiple small activated carbon boards 13.

[0070] Further as Figure 6 , Fig.10 and Fig.11 As shown, it is worth explaining in detail that grooves 105 are provided on both sides of a single side of the inner frame 101, and rubber strips 15 are fixed to multiple edges of the inner frame 101; during specific work, a small activated carbon board 13 and a diatom mud purification board with a certain softness are selected, that is, they have a certain elastic deformation ability, so that the small activated carbon board 13 and the diatom mud purification board can be clamped into the groove 105, so as to conveniently install them on the inner frame 101, and the assembly and disassembly are convenient. The gap between the inner frame 101 and the inner wall of the outer shell 4 is sealed by the set rubber strip 15, so that the purified air is concentrated and discharged through the flow port 108, so as to avoid affecting other small activated carbon boards 13 or diatom mud purification boards.

[0071] Further as Figure 1 , 3 , Figure 4 and Figure 6 As shown, it is worth specifically explaining that the replacement component 3 includes an end rod 301 fixed at the center of the top end of the inner frame 101, a connecting rod 302 is fixed on the top end of the end rod 301, a mounting plate 304 located outside the outer shell 4 is fixed on the end of the connecting rod 302 away from the end rod 301, and a plurality of suction cups 303 distributed equidistantly are fixed on the side of the mounting plate 304; the adsorption component on the replacement component 3 is specifically the suction cup 303, and the end rod 301 is rotated and adjusted, and the end rod 301 synchronously drives the inner frame 101 to rotate and adjust, so as to switch the air purification component. When it is necessary to purify the air at a higher place in the room, the diatom mud purification plate can be switched to the air inlet end 5 by rotating and adjusting the end rod 301. At this time, the end rod 301 exposes multiple suction cups 303 on the mounting plate 304 through the connecting rod 302, so that the whole device can be temporarily hung on the wall for use through the suction cups 303, and the whole device can be placed at a higher place. The diatom mud purification board can effectively adsorb floating bacteria and harmful gases such as ozone in the higher layers of indoor air, and release negative oxygen ions from a higher place. The negative oxygen ions capture and gather dust particles in the descending air, eliminate various unpleasant odors in the air, and further improve the indoor air quality. At the same time, by hanging the whole device to avoid occupying the ground space, the whole device can purify the air at higher and lower places in the room to adapt to a variety of different usage occasions and usage needs.

[0072] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it is worth specifically explaining that the outside of the shell 4 is provided with an outer protective plate 305 fixed to the air inlet end 5, and a slot 306 is opened on the outer protective plate 305, and the suction cup 303 can be rotatably stored in the outer protective plate 305; when the entire device is placed on the indoor floor for use, the suction cup 303 is located in the outer protective plate 305, and the suction cup 303 is covered and protected by the outer protective plate 305 to prevent the suction cup 303 from being exposed to the external environment, greatly reducing the probability of dust and impurities entering the suction cup 303, so that the suction cup 303 always has efficient and stable adsorption performance, when the suction cup 303 is rotated and adjusted to the slot 306, the suction cup 303 is exposed, and the entire device can be temporarily hung on the wall, and at the same time, the diatom mud purification board is prompted to be adjusted to the air inlet end 5, and the diatom mud purification board is used to purify the air, which has an auxiliary prompting effect.

[0074] Further as Figure 4 As shown, it is worth explaining in detail that a bracket 11 fixed to the inner wall of the air inlet end 5 is provided inside the air inlet end 5, a shaft 12 is rotatably connected inside the bracket 11, a plurality of annularly distributed fan blades 14 are fixed on the side of the shaft 12, a small motor 10 is fixed on the bracket 11, and the output end of the small motor 10 is fixed to the shaft 12; during specific operation, the shaft 12 is driven to rotate by the small motor 10, thereby driving the plurality of fan blades 14 on the shaft 12 to rotate, and negative pressure is generated by the rotating fan blades 14, and indoor air is sucked into the air inlet end 5 by the rotating fan blades 14 and is adsorbed, filtered and purified by a small activated carbon plate 13 or a diatom mud purification plate, and the air flow rate is effectively increased by the set fan blades 14, thereby improving the indoor air purification efficiency.

[0075] This scheme has the following working process: when the whole device is placed on the indoor floor for use, the indoor air is initially filtered and purified by the filter screen 6 and then enters the interior of the air inlet end 5, and the air is adsorbed and purified by the small activated carbon plate 13 to remove harmful pollutants such as particulate matter, formaldehyde, bacteria, etc. in the indoor air, so as to effectively purify the indoor air. When one of the small activated carbon plates 13 has been used for purification for a fixed period of time, the inner frame 101 can be rotated and adjusted by rotating the adjustment end rod 301, so that the small activated carbon plate 13 on the inner frame 101 is switched to the air inlet end 5, so as to switch to a new small activated carbon plate 13 to purify the air. At this time, the tongue plate 202 When the round protrusion on the small activated carbon plate is inserted into one of the slots 203, the adjusted position is limited and locked; when one of the small activated carbon plates 13 is rotated to the air inlet end 5, the cavity 104 corresponding to the small activated carbon plate 13 is rotated to the flow port 108 and the cavity 104 and the flow port 108 overlap, so that the air purified by the small activated carbon plate 13 can be discharged into the indoor environment through the cavity 104, the flow port 108 and the air outlet 20, forming a plurality of small activated carbon plates 13 switching and transferring one by one to purify the air, so that the air can be more evenly distributed on each small activated carbon plate 13 for purification, so that the overall purification load of the activated carbon plate 13 is more balanced;

[0076] When it is necessary to purify the air at a higher place in the room, the diatom mud purification board on the inner frame 101 can be switched to the air inlet end 5 by rotating the adjusting end rod 301 and the adjusting inner frame 101. At this time, the end rod 301 rotates the multiple suction cups 303 on the mounting plate 304 to the slot 306 through the connecting rod 302, and the suction cups 303 are exposed, so that the whole device can be temporarily hung on the wall for use through the suction cups 303, and the whole device can be placed at a higher place. The diatom mud purification board can effectively absorb floating bacteria and ozone and other harmful gases in the higher layers of the indoor air, and release negative oxygen ions from a higher place. The negative oxygen ions capture and gather dust particles in the descending air, eliminate odors in the air, and further improve the indoor air quality.

[0077] Further as Figure 3 , Figure 5 and Fig. 9 As shown, it is worth explaining in detail that a replacement port 7 is opened on the side of the shell 4, a cover plate 8 is hinged in the replacement port 7, and a handle is fixed on the outer wall of the cover plate 8; when the air purification component reaches a saturated state, the small activated carbon plate 13 and the diatom mud purification plate are rotated and adjusted to the replacement port 7, and the cover plate 8 is opened, so that the small activated carbon plate 13 and the diatom mud purification plate with a certain softness on the inner frame 101 can be removed and replaced for easy maintenance.

[0079] In summary: the small activated carbon plate 13 is switched and transferred through the set adjustment and cleaning component 1, and the new small activated carbon plate 13 is switched to the air inlet end 5 to purify the air. The larger activated carbon plate as a whole is divided into multiple small activated carbon plates 13 and multiple small activated carbon plates 13 are switched and transferred one by one through the adjustment and cleaning component 1 to purify the air. Since the smaller flow diameter of the air inlet end 5 is facing the small activated carbon plate 13, the air can be more evenly distributed on each small activated carbon plate 13 for purification, so that the overall purification load of the small activated carbon plate 13 is more balanced, and the uneven purification phenomenon caused by excessive local purification load is greatly reduced. When a small activated carbon plate 13 reaches a saturated state, it can be quickly switched to another new small activated carbon plate 13 for purification, thereby ensuring the continuity and efficiency of air purification and fully improving the utilization of the small activated carbon plate 13. When it is necessary to purify the air at a higher place in the room, the adsorption component on the replacement component 3 can be adjusted and exposed through the adjustment and cleaning component 1, so that the entire device can be replaced by the replacement component 3. By temporarily hanging it on the wall for use, the whole device can be placed at a higher place, and the diatom mud purification board can be switched to the air inlet end 5. The structure and characteristics of the diatom mud purification board are the disclosed prior art and will not be described in detail in this application. The diatom mud purification board can effectively adsorb floating bacteria and harmful gases such as ozone in the higher layers of indoor air, and release negative oxygen ions from a higher place. The negative oxygen ions capture and gather dust particles in the descending air, eliminate various unpleasant odors in the air, and further improve the indoor air quality. At the same time, by hanging the whole device to avoid occupying the ground space, the whole device can purify the air at higher and lower places in the room to adapt to a variety of different usage occasions and usage needs; the positioning component 2 is set to prompt the adjustment of the purification component 1, and assist in prompting the small activated carbon board 13 or the diatom mud purification board to switch into place, avoid excessive adjustment, and improve the convenience of use. At the same time, the positioning component 2 is improved to lock the adjusted positions of the small activated carbon board 13 and the diatom mud purification board, so as to improve the working stability of the small activated carbon board 13 and the diatom mud purification board.

[0080] The small motor 10 and the timer can be purchased on the market. The small motor 10 and the timer are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.
