Description

Technical Field

[0001] This utility model relates to the field of air vent cleaning, and in particular to an air vent cleaning device for laminar flow operating rooms. Background Technology

[0002] Currently, Chinese utility model patent CN221618916U discloses a cleaning device for the air outlet of a ducted air conditioner. While this device can drive a brush to clean the air outlet filter plate, it has other problems during use. For example, it lacks a hot air blowing function. Because the air outlet is prone to moisture, dust adheres tightly to the filter plate in a damp state. If the dust is not softened, it creates significant resistance during wiping, reducing the cleaning effect of the device. Furthermore, replacing the brush is inconvenient. Since the device needs to be installed at a high position corresponding to the air outlet, when the brush needs cleaning and replacement after multiple uses, personnel must climb a ladder to the same height, which is not only time-consuming and laborious but also poses certain safety hazards. To solve the above problems, we propose a cleaning device for the air outlet of a laminar flow operating room. Utility Model Content

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model simultaneously activates a suction fan and an electric heating grid. After the suction fan is activated, it pushes outside air into the second fixed frame through the suction port. The air flowing into the second fixed frame passes through the electric heating grid, which converts the air into hot air. The hot air blows downwards through the air outlet onto the filter plate inside the air outlet. Subsequently, the second motor is activated to drive the brush to move laterally. As the brush moves, it wipes the filter plate, causing the dust to fall downwards into the collection box. It has a hot air blowing function, which can soften the dust on the filter plate, making it easier to remove, reducing the resistance and friction during wiping, and ensuring the cleaning effect of the filter plate at the air outlet.

[0022] 2. This utility model involves starting a first motor, which, after starting, drives a first screw to rotate under the fixation of the housing. When the first screw rotates, it drives a first threaded plate to move downwards with the cooperation of a second limiting rod. When the first threaded plate moves downwards, it drives a first fixed frame to move downwards together until the first fixed frame is moved to a contactable position. Finally, the cleaned brush can be replaced with the used one. This makes it easy to replace the brush, is simple and convenient to operate, reduces the workload of personnel, and is highly practical.
