Description

Technical Field

[0001] The utility model relates to the technical field of fresh air fans, in particular to a fresh air fan with a maintenance structure. Background Art

[0002] The fresh air fan is an effective air purification device that can circulate indoor air. On the one hand, it discharges the polluted air indoors to the outside, and on the other hand, it inputs the fresh air outdoors into the room after sterilization, disinfection, filtration and other measures, so that the room is filled with fresh and clean air at all times.

[0003] The fresh air fan uses patented fresh air convection technology to achieve indoor air convection through autonomous air supply and air induction, thereby maximizing indoor air replacement. The fresh air fan has a built-in multi-functional purification system to ensure that the air entering the room is clean and healthy. The fresh air fan is mainly divided into two types: exhaust-type fresh air fans and supply-type fresh air fans. It can be installed in most indoor environments, is easy to install, and comfortable to use. The fresh air fan is a healthy companion for home life. In 1935, Robert Chun invented and manufactured the world's first heat exchange equipment for filtering air pollution, also known as a "fresh air fan."

[0004] For example, publication number CN210320472U proposes a fresh air fan with a maintenance structure. With the progress of the times and the development of science and technology, fresh air fans are used more and more in life. The fresh air fans on the existing market do not have the function of easy maintenance and use. It is inconvenient to replace the filter element during use, and it is not convenient to maintain and replace during normal use; the installation is limited by the structure, the installation is inconvenient, and it is not conducive to user use.

[0005] The above patent points out that it is inconvenient to replace the filter element during use, and it is inconvenient to maintain and replace during normal use. However, the replacement and maintenance components are still not perfect, and not every part that needs to be replaced has the maintenance and replacement function, which brings inconvenience to the user.
