Description
Technical Field
[0001] This utility model relates to the field of tea bar machine technology, specifically to a water circuit structure for a tea bar machine that provides purified drinking water. Background Technology
[0002] In modern life, tea bar machines, as commonly used drinking water devices, have become widely available in homes, offices, and other places. Currently, most tea bar machines on the market have relatively simple water systems, typically only capable of drawing water from a bucket to a kettle. This simple water system design limits the functionality of tea bar machines and makes it difficult to meet the diverse needs of users.
[0003] Conventional tea bar machines cannot perform deep water treatment. If the water source contains impurities, odors, or microorganisms, the tea bar machine cannot effectively purify it, making it difficult to guarantee the health of users' drinking water. On the other hand, due to the simple water circuit, tea bar machines are limited in terms of water temperature adjustment, water output control, and functional expansion. For example, it is difficult to achieve precise multi-stage water temperature control to adapt to the brewing needs of different beverages, and it is also difficult to conveniently realize advanced functions such as refrigeration and ice making, thus failing to meet users' needs for high-quality, multi-functional drinking water equipment.
