Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning equipment, in particular to a maintenance tool for an air-conditioning coil. Background Art

[0002] Air conditioning equipment maintenance is an important measure to ensure the normal operation of air conditioning equipment and extend its service life. Regular maintenance can effectively prevent failures caused by component wear, aging, blockage and other problems, and ensure the stable operation of the air conditioning system. Among them, the air conditioning coil is the key part for heat exchange. Due to the narrow gap between the coil fins, dust and other dirt are easily accumulated and difficult to clean. The accumulated dirt will increase the thermal resistance, reduce the heat transfer coefficient, and reduce the cooling / heating capacity of the air conditioner. Therefore, it is necessary to clean the coil fins regularly to ensure the proper heat exchange performance of the air conditioner.

[0003] There are already some cleaning tools on the market that are specifically used to clean smaller gaps. For example, the utility model patent with authorization announcement number CN213996935U discloses an all-in-one cleaning machine with a deep cleaning function, including a box body, a handle fixedly provided at the bottom end of the box body, and a button provided on one side of the handle, and a battery is provided inside the box body, and a motor is provided on one side of the battery, and a mounting plate is provided on one side of the box body, and a connecting rod is inserted and connected to the mounting plate, and a dust cover is provided on the outside of the connecting rod.

[0004] The above-mentioned integrated cleaning machine achieves cleaning by rotating the scraper and the brush head. However, due to the extremely small spacing between adjacent fins (usually 2-3 mm), the hard scraper structure of the integrated cleaning machine can only clean the area in front of the scraper when cleaning the coil, and cannot go deep into the fin gap of the coil to clean, which ultimately leads to incomplete cleaning of the coil and is difficult to meet the maintenance needs of the air conditioning coil.
