[0025] In order to solve the technical problem that existing fresh air systems cannot meet people's needs for disinfection of indoor air, this utility model provides a disinfection device for the air outlet of a fresh air system.

[0026] like Figs. 1-2 As shown, this utility model provides a disinfection device for the air outlet of a fresh air system. The disinfection device includes a housing 10, and a receiving cavity is formed inside the housing 10. The housing 10 has a first opening 11 and a second opening 12 communicating with the receiving cavity. The first opening 11 is used for detachable connection with the air outlet of the fresh air system, and the second opening 12 is in communication with the indoor air. Thus, the air entering the room through the fresh air system enters the receiving cavity through the first opening 11, is disinfected in the receiving cavity, and then enters the room through the second opening 12, thereby improving the cleanliness of the air entering the room.

[0027] The first opening 11 is provided with a first filter section 13 that can cover the first opening 11. The first filter section 13 can filter the gas entering the receiving cavity. The receiving cavity is provided with a second filter section 14, which divides the receiving cavity into a first chamber communicating with the first opening 11 and a second chamber communicating with the second opening 12. Thus, the gas entering the receiving cavity is filtered a second time by the second filter section 14. The second filter section 14 is provided with a heating section 16, which is used to continuously heat at least a part of the second filter section 14. The aperture of the first filter section 13 is larger than the aperture of the second filter section 14. By providing a heating section 16 on the second filter section 14, the second filter section 14 can be continuously heated, thereby further disinfecting the air entering the room through the fresh air system.

[0028] Because airborne pathogens are more active and have a longer survival time in cold environments, but have a shorter survival time in hot environments (for example, some viruses are completely inactivated in 30 minutes at 56°C), this invention, by setting a heating element 16 that can continuously heat the air in the fresh air system, can effectively kill the pathogens adsorbed on the second filter element 14 after the airborne pathogens are adsorbed by the second filter element 14 by continuously heating the second filter element 14. This disinfects the air entering the room and further disinfects any viruses that may exist in the fresh air system, which helps to ensure the cleanliness of the air entering the room.

[0029] At the same time, by setting up the second filter 14, it is also possible to prevent pathogens that may exist in the indoor air from entering the fresh air system through the second opening and causing pollution to the internal components of the fresh air system.

[0030] Furthermore, the outer casing 10 includes a first casing and a second casing, wherein the first casing and the second casing are detachably connected, and the second filter section 14 is disposed inside the first casing at a position away from the first opening 11; with this arrangement, when the second filter section 14 needs to be replaced, it can be replaced simply by removing the second casing, making the replacement of the filter section more convenient and effectively preventing viruses from accumulating inside the outer casing 10.

[0031] Specifically, the first housing and the second housing can be connected by threads, for example, with matching internal and external threads at the connection point, thereby achieving the connection between the first housing and the second housing through threaded connection; of course, the first housing and the second housing can also be connected by other means such as snap-fit ​​connection.

[0032] To facilitate connection of the heating element 16, the outer casing 10 is provided with a through hole for electrical connection of the heating element 16, thereby enabling the heating element 16 to be connected to an external power source for power supply. Alternatively, for a lower-power heating element 16, a battery can be installed within the housing cavity to supply power.

[0033] In one specific embodiment of this utility model, the second filter part 14 includes a first frame, a second frame, and a filter cloth, wherein the first frame is fixedly connected to the first housing, the second frame is detachably connected to the first frame, and the filter cloth is located between the first frame and the second frame and is clamped and fixed by the first frame and the second frame; this layout, which clamps the filter cloth between the first frame and the second frame, facilitates the processing and fixing of the product.

[0034] Furthermore, the filter cloth is meltblown cloth or polyurethane air filter cotton. By setting materials that can filter and adsorb pathogens, it is possible to filter the air entering the room and prevent pathogens from entering the room through the fresh air system and affecting people's health.

[0035] Specifically, the heating part 16 includes heating wires, which are disposed on the filter mesh and arranged in a serpentine pattern on the filter mesh, thereby enabling uniform heating of the filter mesh.

[0036] In another specific embodiment, the disinfection device may also include a control unit, and a temperature sensor is also provided on the second filter unit 14. Based on the data monitored by the temperature sensor, the control unit can control the heating unit 16 to control the heating temperature and heating time of the second filter unit. For example, by controlling the heating unit 16, the second filter unit 14 can be heated so that the temperature of the second filter unit 14 is always higher than a preset threshold and remains above a preset time range.

[0037] Furthermore, a third filter section 15 is provided on the second opening 12 to cover the second opening 12; thereby enabling the filtration of the air entering the room; at the same time, when the fresh air system is not applicable, it can prevent dust and other debris in the room from entering the interior of the outer casing 10 through the second opening 12.

[0038] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0039] 1. Effectively solves the technical problem that existing fresh air systems cannot meet people's needs for indoor air disinfection;

[0040] 2. The structure is simple, easy to install and replace, and conducive to the disinfection of indoor air.
