Description

[Technical Field]

[0001] This utility model relates to the technical field of water cup products, and in particular to a water cup with a filter function that has a reasonable structural design and a high user experience. [Background Technology]

[0002] Water cups are common items in people's daily lives. In order to further improve the practicality of water cups, water cup products with filtration functions have appeared on the market. Filtered water cups mainly use filter cartridges to purify drinking water, thereby providing consumers with clean drinking water that is easy to carry and beneficial to human health.

[0003] The main problems with existing water filter cups are: mediocre filtration effect, complex internal filtration structure, and difficulty in disassembly and cleaning.

[0004] For example, utility model patent application number CN201721008510.9, entitled "A Filtered Water Cup," specifically discloses a filtered water cup, including a cup body, a filter element, a water storage shell, and a cup lid. The lower end of the water storage shell is detachably and sealed to the cup body, and the upper end is detachably and sealed to the cup lid. The inner wall of the water storage shell is sealed to the outer periphery of the filter element. A water storage cavity is formed between the filter element, the cup lid, and the water storage shell. A vent pipe is provided through the filter element, connecting the water storage cavity and the inner cavity of the cup body. A vent switch device is provided inside the vent pipe. The vent switch device blocks the vent pipe when the filtered water cup is upright and opens the vent pipe when the filtered water cup is inverted. When filling with water, the water storage shell and the cup lid are removed, water is directly poured into the cup body, and then the water storage shell and the cup lid are fixed to the mouth of the cup. During filtration, the water cup is inverted, allowing gas in the storage chamber to enter the cup through the vent tube, while water in the cup flows through the filter cartridge back into the storage chamber, thus achieving filtration. This filtered water cup is very convenient to fill, and the filtration method is simple and easy to use, improving the user experience.

[0005] To further improve the performance of the water filter cup, improvements and enhancements are needed in aspects such as the specific filter layer structure and the filter mechanism. [Utility Model Content]
