Filtration device

Abstract

This invention relates to a filtration device, characterized in that the filtration device comprises: a main body, a filter structure, and an elastic reset structure, wherein the filter structure is placed inside the main body, allowing water to enter the main body, pass through the filter structure, and flow out from the discharge end of the main body; the elastic reset structure is disposed at the discharge end of the main body, and when the main body is subjected to force, the elastic reset structure collapses or resets, making the main body displaceable; the main body is fitted into a filter box, and when the main body moves back and forth, a fluid pressure difference is generated in the dirt collection area between the discharge end and the filter box, guiding the wastewater after cleaning the filter structure to collect in the dirt collection area and discharge it out of the filter box through the drain port. This structure has many advantages, including simple structure, rapid cleaning, no need to disassemble the filter structure, and improved cleaning efficiency.

Claims

1. A filtration device, comprising: A main body having an open end and a discharge end; a filter structure inserted into the main body through the open end, allowing water to enter the main body, pass through the filter structure, and then flow out through the discharge end; and an elastic reset structure disposed at the discharge end of the main body, which collapses when the main body is subjected to force and resets when the force is released, allowing the main body to be displaceable through the elastic reset structure.

2. The filtration device as claimed in claim 1, wherein the main body is in the shape of an elongated trough and is fitted into a filter box, the filter box having at least one guide portion, the main body being correspondingly disposed on the guide portion and constrained by the guide portion to generate a reciprocating displacement trajectory; when the main body is subjected to force and displaces along the guide portion, the elastic reciprocating structure is compressed, and the filtration structure and the water flow generate relative motion to form a flushing water flow, which flows out from the discharge end.

3. The filtration device as described in claim 2, wherein the bottom of the filter box is provided with a dirt collection area and a drain outlet corresponding to the discharge end of the main body, and when the main body moves back and forth, a fluid pressure difference is generated between the discharge end and the dirt collection area, which guides the wastewater after cleaning the filter structure to collect in the dirt collection area and discharge it out of the filter box through the drain outlet.

4. The filter device as described in claim 3, wherein a baffle is provided on one side of the guide portion of the filter box, and the height of the guide portion is lower than that of the baffle, thereby forming a flow guiding space between the guide portion and the baffle.

5. The filter device as claimed in claim 1, wherein the resilient reset structure comprises any one or a combination of a spring, a soft block, an elastic block, or a polymer material.

6. The filtration device as claimed in claim 1, wherein the filtration structure comprises a multilayer or single layer of polypropylene fibers, activated carbon, resin, hollow fiber membrane, or nonwoven fabric.
