Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a sterilizing filter device. Background Art

[0002] Precision filters are widely used in various fields. In the industrial field, precision filters are used to purify substances such as gases, liquids and solids. For example, in the electronics, medicine, chemical, food and other industries, precision filters are indispensable purification equipment. In addition, precision filters are also used in environmental protection, energy and other fields, such as water treatment, air purification, etc. However, precision filters only have the functions of interception and filtration, and cannot play a sterilization role. This will result in the bacteria intercepted by the filter cannot be effectively treated, and then continue to reproduce and regenerate inside the filter, eventually leading to serious filter blockage; in scenarios with high bacterial requirements, there are serious safety hazards.

[0003] In the field of water treatment, there is a high demand for sterilization. Currently, a set of ultraviolet sterilization devices is often added to the front end of the precision filter. However, due to the irregularity of the device and the filter, the pipe connecting the two devices is long, which increases the risk of bacterial growth; and the equipment footprint will also increase. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a sterilizing and filtering device, which has the functions of sterilization and interception, reduces the risk of bacterial growth, and has a compact structure and occupies little area.

The liquid filtered by the filtration unit passes through the second channel and the confluence in turn, and finally flows out of the device. The device integrates the sterilization unit and the filtration unit into one. The path of the liquid from sterilization to filtration is short and the entire process is in a closed environment, which greatly reduces the risk of bacterial growth. In addition, the layout of the sterilization unit and the filtration unit is optimized, making the structure of the device more compact and reducing the footprint of the device.
