AI Technical Summary
Technical Problem
When disassembling or replacing the filter, internal water can easily leak out, causing damage to other components and increasing the user's cleaning workload.
Method used
Design a filter including a bottle body, a filter element and an end cap. The end cap has a liquid outlet channel, and there is a gap channel between the bottle body and the end cap. The gap channel includes a liquid inlet channel and a water-stop slit. The width of the water-stop slit is smaller than that of the liquid inlet channel, forming multiple leak-proof barriers to ensure water-stopping effect during disassembly.
Benefits of technology
It effectively prevents liquid leakage, avoids component damage, simplifies user operation, and improves the filter's sealing performance and convenience.

Abstract
The application provides a filter, a water purifying device and a refrigeration equipment, and the filter comprises a bottle body provided with a bottle opening, a filter element arranged in the bottle body, and an end cover arranged in the bottle body and located at one end of the filter element close to the bottle opening, wherein the end cover is provided with a liquid outlet channel, at least part of the outer surface of the end cover has a gap channel with the bottle body, the gap channel comprises a liquid inlet channel and at least two water stop slits, the width of the water stop slit is smaller than the width of the liquid inlet channel, the gap channel is communicated with the liquid outlet channel through the filter element, and the at least two water stop slits are arranged at intervals along the length direction of the bottle body, and any water stop slit is arranged in a circle along the circumferential side of the end cover. The filter provided by the application can form multiple leakage prevention barriers by arranging the at least two water stop slits at intervals along the length direction of the bottle body, and the sealing performance of the whole circle is ensured by arranging any water stop slit in a circle along the circumferential side of the end cover.
