Description

Technical Field

[0001] The utility model belongs to the technical field of liquid reservoirs, and particularly relates to an anti-clogging liquid reservoir with an integrated filter screen and a supporting frame. Background Art

[0002] Current reservoirs such as Figure 1 As shown, two metal brackets are used. Filter membranes c are installed on both brackets. The molecular sieve, or desiccant assembly, is bundled on the guide tube between the two metal brackets. The upper edge of the upper bracket a is clamped inward by the action of the inner wall of the cylinder, and the lower bracket b is stuck by the protrusion on the guide tube. The molecular sieve is subjected to vibration and pressure for a long time, and the desiccant inside will gradually accumulate downward on the lower bracket b. In addition, impurities are filtered through the filter membrane and accumulate on the filter membranes of the upper bracket a and the lower bracket b. Over time, the filter membrane will become clogged, resulting in increased flow resistance. Under high flow resistance, the lower bracket b will bend due to excessive pressure and will not rebound, resulting in deformation. The gap between the deformed metal bracket and the cylinder, and the falling of the molecular sieve will cause the equipment to make abnormal noises, and in severe cases, the air conditioner will stop running.

[0003] Therefore, a new technical solution is urgently needed in the existing technology to solve this problem. Utility Model Content
