However, the internal environment of indoor air purification devices is complex. The ultraviolet lamps can effectively sterilize the light source and the airflow. When the indoor environment is humid, especially during the rainy season, mold may grow in the dead corners inside the indoor air purification and sterilization device, which will affect its air purification and sterilization effect. Utility Model Content

The inner side of the breathable middle cylinder and the inner filter cylinder are made of stainless steel and the outer layer is wrapped with an aerogel layer, which can play a heat insulation role for the heating tube, prevent the heating tube from transferring heat to the outer shell, and thus prevent the user from being burned.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This application provides a technical solution: an indoor air purification and sterilization device, including a shell 1. A set of ultraviolet lamps 7 and a ventilated cylinder 4 are fixedly installed sequentially from the outside to the inside of the inner bottom wall of the shell 1. A temperature sensor 6 is fixedly installed on the inner bottom wall of the ventilated cylinder 4. A set of heating tubes 5 arranged in a ring are fixedly installed on the inner bottom wall of the ventilated cylinder 4 surrounding the temperature sensor 6. An inner filter cylinder 3 is provided above the heating tubes 5. Multiple sets of air outlets 14 are opened on the outer wall of the shell 1. An air inlet mechanism is provided at the upper end of the inner filter cylinder 3. (See attached...) Figure 2 The heating element 5 is located downstream of the air inlet path, and an inner filter cartridge 3 is coaxially arranged above it.

[0022] In the technical solution of this application, air can be introduced into the inner filter cylinder 3 through the air inlet mechanism, so that the inner filter cylinder 3 can filter the airflow particles. After the airflow passes through the inner filter cylinder 3, it can be heated and dried by the heating tube 5, thereby reducing the relative humidity.

[0023] Furthermore, the annularly arranged heating tubes 5 can uniformly heat the airflow filtered by the inner filter cartridge 3 from all 360 degrees, avoiding localized overheating. The temperature sensor 6, located in the core heating area, provides real-time temperature feedback, preventing damage to the filter cartridge or outer shell due to excessive heat. The temperature sensor 6 also detects the internal temperature. After passing through the vented middle cylinder 4, the airflow is further disinfected by the ultraviolet lamp 7 before flowing out through the air outlet 14 of the outer shell 1. During this flow, the heated airflow can also heat and dry different parts of the device, preventing mold growth caused by moisture and enhancing the air purification effect.

[0024] In the technical solution of this application, such as Figures 1-3 As shown, a cover 10 is fixedly installed on the upper end of the outer shell 1. The end cap 11 can shield the outer shell 1. The end cap 11 is screwed onto the inner wall of the cover 10. Multiple air inlets 12 are provided on the upper side of the end cap 11. A handle 13 is fixedly installed on the upper end of the end cap 11. The cover 10 can screw the end cap 11 onto the end cap. The handle 13 makes it convenient for workers to install the end cap 11. The air inlets 12 facilitate airflow into the inner filter cartridge 3. An inner fixed cylinder 2 is fixedly installed on the lower end of the end cap 11. Multiple sets of air inlets 12 are located between the inner fixed cylinders 2. The inner fixed cylinders 2 can be fixed by the end caps 11. The air intake mechanism includes a fan bracket 8 fixedly installed on the inner wall of the inner fixed cylinder 2. The fan body 9 is fixedly installed at the lower end of the fan bracket 8. The inner filter cylinder 3 is spirally installed with the inner fixed cylinder 2. The fan bracket 8 can be fixed by the inner fixed cylinder 2, and the fan bracket 8 can be fixed by the fan body 9. The fan body 9 can draw in the air from the outside with the cooperation of the air inlets 12 and deliver the air to the inner filter cylinder 3.

[0025] Understandably, the air intake mechanism is integrated inside the inner fixed cylinder 2, which includes a fan bracket 8 fixedly installed on the inner wall of the inner fixed cylinder 2, and a fan body 9 fixed to the lower end of the bracket. The upper end of the inner filter cartridge 3 is connected to the inner fixed cylinder 2 by threads. The suspended structure design makes the fan body 9, the inner fixed cylinder 2, and the inner filter cartridge 3 form an integral component. When the user unscrews the end cap 11 using the handle 13, the entire filtration and air intake module can be lifted out at once, greatly facilitating the cleaning or replacement of the inner filter cartridge 3 and solving the problem of cumbersome disassembly in traditional air purifiers.

[0026] In the technical solution of this application, such as Figure 2 and Figure 4 As shown, the breathable inner cylinder 4 and the inner filter cylinder 3 are made of heat-insulating materials. The middle layer of the breathable inner cylinder 4 and the inner filter cylinder 3 is made of stainless steel, and the outer layer includes an aerogel layer. The breathable inner cylinder 4 and the inner filter cylinder 3 are made of stainless steel, and the outer layer is wrapped with an aerogel layer, which can insulate the heating tube 5, preventing heat transfer from the heating tube 5 to the outer shell 1, thereby preventing burns to the user. It should be noted that the main body is made of middle stainless steel to ensure strength, and the outer wall (in areas without vents) is covered with an aerogel layer. This means that both the inner filter cylinder 3 and the breathable inner cylinder 4 have mesh openings for airflow, and the aerogel layer only covers the skeleton connections between the mesh openings, or a porous, breathable aerogel material may be used. By utilizing the extremely low thermal conductivity of aerogel, when the heating tube 5 generates a hot airflow of 40-60℃, it effectively blocks the transfer of heat to the outer shell 1, ensuring that the surface temperature of the outer shell 1 is within the safe range for human contact and preventing burns to the user. At the same time, the heat energy is locked inside the device for sterilization and drying, thus improving energy utilization efficiency.

[0027] In use, the user unscrews the end cap 11 from the housing 10 by rotating the handle 13 on the end cap 11. This causes the inner fixed cylinder 2 and inner filter cylinder 3 to be removed, facilitating the cleaning of impurities. When the fan body 9 rotates at high speed, a negative pressure is created through multiple air inlets 12 on the end cap 11, drawing outside air between the inner fixed cylinder 2 and the inner filter cylinder 3. Larger particles such as dust and hair are intercepted by the inner filter cylinder 3, and the filtered airflow continues to flow outwards. The airflow reaches the heating tube 5, where it is heated and dried, reducing moisture production. A temperature sensor 6 monitors the temperature in this area, ensuring the airflow temperature remains between 40-60℃. Within a suitable range, the airflow effectively reduces the moisture content of the air. After passing through the breathable cylinder 4, the heated airflow enters the ultraviolet lamp 7. The ultraviolet lamp 7 can photolyze and destroy microorganisms such as bacteria and viruses in the airflow, thus achieving a triple treatment of filtration, drying and sterilization. The airflow is evenly discharged through multiple sets of air outlets 14 on the side wall of the outer shell 1. During this process, the heated airflow continuously circulates and acts on the surfaces of various components inside the device, including the inner wall of the outer shell 1, the outer layer of the breathable cylinder 4 and the outer periphery of the inner filter cylinder 3. The residual moisture is removed by heat convection, preventing the oxidation of metal parts or the mold growth of plastic parts caused by long-term humid environment. At the same time, maintaining a dry environment inside the device can improve the sterilization efficiency of the ultraviolet lamp 7. The temperature of the outer wall of the breathable cylinder 4 and the inner filter cylinder 3 wrapped by the aerogel layer is always below 45°C, effectively preventing burns when the user touches the outer shell 1.

[0028] In addition, the main body of the fan 9 generates negative pressure when it starts, and outside air is drawn in through the air inlet 12 on the end cover 11. The airflow first enters the interior of the inner filter cartridge 3 and passes through the filter layer from the inside to the outside. At this time, dust, hair and particulate matter in the air are intercepted by the inner filter cartridge 3, achieving the first stage of physical purification.

[0029] The filtered, clean airflow flows downwards and contacts the heating element 5. The heating element 5 rapidly heats the airflow to a set temperature, preferably, such as 50°C. During this process, the high temperature reduces the relative humidity of the air, turning the airflow into dry, hot air. A temperature sensor 6, in conjunction with a controller (not shown in the figure), maintains a constant temperature. The dry, hot environment destroys the survival conditions for mold, achieving a second stage of mold prevention and dehumidification.

[0030] The dry, hot airflow then passes through the ventilated inner cylinder 4 and enters the annular cavity between the outer shell 1 and the ventilated inner cylinder 4. In this area, a set of ultraviolet lamps 7 irradiate the flowing air with high intensity, destroying the DNA / RNA structure of bacteria and viruses, achieving third-stage photolysis sterilization. Finally, the triple-treated airflow is discharged into the room through multiple sets of vents 14 on the outer wall of the outer shell 1.

[0031] Understandably, the heated airflow continuously conducts heat to dry the inner wall of the outer casing 1, the ventilated middle cylinder 4, and the outer wall of the inner filter cartridge 3 during the exhaust path. The advantage of this structural design is that it automatically removes condensate or moisture that may accumulate in the dead corners inside the device using the exhaust waste heat, fundamentally eliminating the risk of mold growth inside the purifier during the rainy season, extending the filter life, and enhancing the actual air purification effect.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
