Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water treatment, and particularly relates to a drinking water treatment device. BACKGROUND

[0002] In the field of domestic drinking water treatment, users have extremely strict requirements for the comprehensive performance of water purification equipment: not only is it required to produce water with safe and reliable quality and a sweet taste, but also the equipment is required to be efficient and energy-saving, compact in size, easy to install, and simple to maintain. Ozone (O3) sterilization technology has become one of the important options for meeting the high-standard disinfection needs of households due to its high efficiency and the absence of harmful by-products. However, when this technology is integrated into household equipment, its inherent technical bottlenecks seriously restrict user experience.

[0003] The current household ozone water treatment scheme generally uses a Venturi injection method to adapt to the limited internal space. This type of method is difficult to fully break and refine ozone bubbles, resulting in insufficient gas-liquid contact area, low ozone dissolution rate, and unsatisfactory sterilization efficiency. More importantly, due to the compact internal structure of household equipment, the water flow path is short, and the effective contact time of ozone and water is severely insufficient, making it difficult to achieve the CT value (concentration x time) required for reliable sterilization. This directly leads to the existence of a disinfection blind area, which poses a risk to the biological safety of the effluent, and cannot meet the absolute requirements of the household environment for drinking water safety.

[0004] In view of the above-mentioned defects in the prior art, the present application is produced as a result of in-depth research. SUMMARY
