[0002] The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment. The heating system provides the required heat for the air conditioning system to offset the cold and warm loads of the indoor environment. The air purification device is an extremely important part of the central air conditioning system and is responsible for filtering the gas in the pipes.

[0003] However, the following problems still exist in the actual operation process: the air purification device is installed inside the central air-conditioning duct through a medium-efficiency filter during daily use. However, during the long-term filtering process, dust will adhere to the medium-efficiency filter, which will cause the mesh to be blocked, and the overall purification effect will be poor. In addition, the internal dust can only be cleaned by blowing air into the duct through the equipment. For this reason, the utility model provides an air purification device for a central air-conditioning system. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The air purification device for the central air conditioning system pre-inserts the medium-efficiency filter into the interior of the installation shell, and then contacts and abuts the bottom of the medium-efficiency filter through the limit plate, and then engages with the installation screw on the side of the limit plate through the linkage plate, and then realizes the locking and limiting of the installation screw through the threaded connection relationship between the internal threaded sleeve and the installation screw, and controls the spring to shrink on the side of the connecting circular plate through the linkage plate, and at the same time, the damping rod on the side of the linkage plate shrinks together, so that the linkage plate can be controlled to move out from the surface of the installation screw, and then the limit plate is removed to replace the medium-efficiency filter. During the whole operation, the medium-efficiency filter can be effectively replaced regularly, and the blockage of the mesh caused by the long-term use of the medium-efficiency filter and the deterioration of the overall purification effect can be avoided.
