[0006] In the above-mentioned air conditioning filter, the water inlet end and the water outlet end of the straight copper tube are both configured with constricted ends, and the filter assembly is axially limited between the water inlet end of the straight copper tube and the buffer partition.

[0007] In the above-mentioned air conditioning filter, there are more than three front positioning recesses and rear positioning recesses evenly distributed around the axis of the straight copper tube, and the positions of the front positioning recesses and the rear positioning recesses are opposite to each other.

[0008] In the above-mentioned air conditioning filter, a plurality of flow through holes are evenly distributed in the circumferential direction around the axis of the buffer partition.

[0010] The outstanding advantages of the utility model compared with the prior art are:

[0011] The utility model has a simple structure and a reasonable design. By adding a buffer baffle in the straight copper tube, the turbulent liquid passing through the filter component is effectively drained by means of the flow through hole, so as to effectively reduce the flow sound. In addition, the buffer baffle can be firmly fixed in the straight copper tube by means of the front positioning recesses and the rear positioning recesses distributed front and back. The connection is simple, firm and low-cost. Description of the drawings:
