Description

Technical Field

[0001] The utility model relates to the technical field of drainers, and in particular to a bouncing filter basket, a double-layer filter assembly and a drainer. Background Art

[0002] The existing drainer generally includes a cup body, a main body, a filter basket and a sealing cover, wherein the cup body and the main body are fixed by clamping the water tank, and the filter basket is placed in the main body. When drainage is required, the sealing cover is opened, and when water is required, the sealing cover is pressed into the main body. Since the sealing cover is not connected to the drainer, it is easy to be lost after opening and is placed everywhere, affecting the appearance. Therefore, a bouncing type water discharger has appeared, which can seal or separate the sealing cover from the main body by pressing the bouncing core, such as a water discharger filter screen disclosed in Chinese patent CN217500432U. When the bouncing core is pressed to raise the sealing cover of the bouncing assembly to open the water discharger for discharge, the water flows into the water discharger shell chamber from the gap between the sealing cover and the water discharger shell, and leaks out from the filter holes of the water discharger filter screen and the water leakage holes of the water discharger shell in turn, enters the water discharge hole and is discharged from the subsequent pipeline, and the impurities such as hair in the water flow will be blocked by the filter holes of the water discharger filter screen in the water discharger shell chamber. When the impurities in the water discharger filter screen accumulate to a certain extent, the bouncing assembly and the water discharger filter screen can be directly taken out from the water discharger shell. In this scheme, the sealing cover is located above the filter screen and the filter hole, and the water flow can only enter from the gap between the sealing cover and the water discharger shell, which is easy to cause garbage to accumulate in the gap and cause blockage, affecting the drainage speed. At the same time, the garbage accumulation in the gap is also easy to affect the sealing performance of the sealing cover. Utility Model Content
