Description

Technical Field

[0001] The utility model relates to the field of air purification equipment, in particular to a pipeline air disinfector and a fresh air system. Background Art

[0002] Existing fresh air system duct disinfection machines need to be connected to the original ventilation ducts with power cords, which affects the appearance and consumes manpower and material resources. The laying of excessively long power cords will cause electrical safety issues. At the same time, if holes are opened in existing ducts, there will be air leakage problems, which will affect the airflow of the ventilation system. When users install disinfection machine modules at the air inlet or outlet of the fresh air system, they usually need to purchase models of different sizes and structures. In addition, when the ion disinfection machine is installed in the fresh air system duct, it is limited by the different sizes and shapes of the ducts, and a customized mounting bracket is required to seal and fix it, which greatly affects the convenience and cost of user installation. Utility Model Content

[0003] The first object of the utility model is to provide a pipeline air disinfector which can avoid connecting a power line in the pipeline.

[0004] The second object of the present utility model is to provide a fresh air system using the above-mentioned pipeline air disinfector.

[0005] To achieve the above-mentioned first objective, the present invention provides a duct air disinfector, which is configured to be installed in a duct. The duct air disinfector further includes a disinfector body and a body fixing portion, wherein the disinfector body is connected to the duct via the body fixing portion. The disinfector body includes a battery and a disinfection module, wherein the battery is electrically connected to the disinfection module. Alternatively, the disinfector body includes a first power generation component and the disinfection module, wherein the first power generation component is electrically connected to the disinfection module.

[0006] As can be seen from the above solution, by using a battery to power the disinfection module, or directly powering the disinfection module through the first power generation component, there is no need to lay power cables, thus avoiding aesthetic issues, electrical safety issues, and air leakage in the pipes. At the same time, by installing the disinfection machine body in the pipe, it can kill viruses, bacteria, and deodorize the air before it enters the room, providing users with a better fresh air experience.

[0007] A preferred solution is that the disinfection machine body includes an outer shell, a disinfection component and a bottom shell, and the bottom shell is arranged at the bottom end of the outer shell; the battery and the disinfection module constitute the disinfection component, or the first power generation component and the disinfection module constitute the disinfection component; at least a part of the disinfection component is located in the accommodating cavity surrounded by the outer shell and the bottom shell, and a first fixing part is provided on the bottom shell.

[0008] A further solution is that the ducted air disinfector also includes a disinfector body and a mounting bracket; the mounting bracket includes a support rod and a fixed base, the support rod is detachably fixedly connected to the bottom shell, a second fixing part is provided on the fixed base, and the body fixing part is located on the first fixing part or the second fixing part.

[0010] As can be seen from the above, by setting the mounting bracket to be detachably connected to the sterilizer body, and setting fixing parts on the bottom shell of the sterilizer body and the fixed base of the mounting bracket, the user can choose the setting position and fixing method according to the shape and size of the pipeline space. The first fixing method of the duct air sterilizer is to fix it on the pipeline through the second fixing part, and bend it into the required installation direction and angle through the flexible support rod, so that the product can play the maximum use effect; the second fixing method is to remove the mounting bracket and fix it on the pipeline or the air inlet of the fan through the first fixing part. The duct air sterilizer is suitable for use in pipeline spaces with small spaces and complex shapes, thereby effectively solving the problem that users find it difficult to install the duct air sterilizer when faced with various complex shapes of pipelines and limited space, improving the versatility of the duct air sterilizer, and realizing multiple uses of one machine. At the same time, it is only fixed by screws, bonding, or magnetic attraction, which can improve the convenience of installation.

[0011] A further solution is that the support rod is made of metal material.

[0017] As can be seen, by installing the first power generation assembly and utilizing wind power to generate electricity independently, there is no need to drill holes in the pipeline to connect the power line, thereby improving the pipeline's sealing and preventing air leakage. This also avoids the need to replace batteries, such as dry cells, when using primary batteries. Furthermore, the battery can store excess power generated by the generator for future use.

[0018] A further solution is that at least two ventilation holes are opened on the shell wall of the fan cover, and multiple ventilation holes are arranged along the circumference of the fan cover; the ventilation holes penetrate the shell wall in the thickness direction of the shell wall; the fan cover has a connecting end and an opening end, the connecting end is fixedly connected to the outer shell, and the inner diameter of the fan cover gradually increases from the connecting end to the opening end.

[0021] Thus, by installing a second power generation module and utilizing wind power for autonomous power generation, there is no need to drill holes in the pipeline to connect power lines, thereby improving the pipeline's sealing and preventing air leakage. This also avoids the need to replace batteries when using primary batteries such as dry cells.
