Lifting-cage type water tank filter

Abstract

The invention provides a lifting-cage type water tank filter. The lifting-cage type water tank filter includes a cup-shaped main body, a sliding claw sleeve and a driving device, wherein the sliding claw sleeve externally and rotatably sleeves the cup-shaped main body; a bottom plate is mounted at the bottom of the sliding claw sleeve; the upper surface of the bottom plate abuts against the lowersurface of the bottom of the cup-shaped main body; a plurality of lower filtering holes penetrating through the bottom plate in the vertical direction are formed in the bottom plate; a plurality of upper filtering holes penetrating through the bottom of the cup-shaped main body in the vertical direction are formed in the bottom of the cup-shaped main body; the upper filtering holes are located above the lower filtering holes, and a part of the upper filtering holes overlap with a part of the lower filtering holes to form a channel for fluids to flow through; and the driving device is mounted on the cup-shaped main body for driving the sliding claw sleeve to rotate around the axis of the cup-shaped main body to change the size of the channel. According to the lifting-cage type water tank filter, the size of the channel is convenient to adjust, and according to the size of solid impurities, the filtering speed is convenient to adjust.

Description

technical field [0001] The invention relates to the field of filters, in particular to a cage-type water tank filter. Background technique [0002] The sink is a device that is often used in life and can be used to clean hands and other objects. Generally speaking, a sink has multiple purposes, for example, cleaning, washing, washing kitchen utensils or fruits and vegetables. The bottom of the existing kitchen sink has a through hole; the through hole communicates with the drainage pipe to discharge sewage, and a sink filter is placed in the through hole for filtering operation, and there are several holes for fluid to pass through the sink filter. filter hole. During actual use, water is poured into the sink, and the water enters the drainpipe through the filter hole and is discharged, and solid debris is intercepted in the filter of the sink. [0003] When cleaning different foods, the volume of solid debris contained in the cleaned wastewater varies. For example, when...

AI Technical Summary

Problems solved by technology

The filter holes on the sink filter are too large to intercept fine solid impurities; the filter holes on the sink filter are too small to slow down the water leakage.

However, the size of the filter holes on the existing tank filter cannot be adjusted. In order to meet the versatility, people have to use a tank filter with less filter holes.
