1. A connection structure for a filtration device, comprising:
a main shell body (100) having a filtering component (110) disposed therein;
a mounting section (200) assembled at one end of the main shell body (100), the mounting section (200) having an inlet (210) and an outlet (220);
a switch section (300) assembled at another end of the main shell body (100); and
an installation section (400) passing through the main shell body (100), one end of the installation section (400) being fixedly assembled to the switch section (300) and another end of the installation section (400) extending from the mounting section (200);
wherein, when the switch section (300) is toggled in one direction, the switch section (300) drives the installation section (400) to rotate and be inserted into a mounting hole on a refrigerator, the inlet (210) and the outlet (220) are correspondingly connected to a refrigerator pipeline, and water flows through the filtering component (110) to filter out impurities, and
wherein the switch section (300) includes: a housing (310), a stationary shaft (320) fixedly assembled onto the housing (310), a sleeve (330) rotatably assembled onto the stationary shaft (320), a toggle switch (340) arranged on the sleeve (330), a first gear (350) fixedly assembled onto the sleeve (330), and a second gear (360) fixedly assembled onto the installation section (400) and engaged to the first gear (350).
