Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to an intelligent direct drinking water supply and sales system and a water supply method thereof. Background technique [0002] At present, with the improvement of people's living standards, the demand for direct drinking water has increased significantly, and the technology of direct drinking water supply has continued to develop thereupon. Direct drinking water supply equipment usually consists of a water supply module, a filter assembly and a filter membrane assembly. After the raw water delivered by an external water source enters the water supply module, the water supply module transports the raw water to the filter assembly and the filter membrane assembly for treatment to obtain direct drinking water. drinking water. Chinese Patent No. CN2012201564775 discloses a non-negative pressure direct drinking water preparation and water supply device. In the technical...
