Description

Technical Field

[0001] The utility model belongs to the technical field of drinking water filtration, and particularly relates to an ultrafiltration component for purifying a water cup. Background Art

[0002] Among the numerous water purification cup products at home and abroad, the filter element material generally uses one or several active materials such as granular activated carbon. These materials are directly installed in the water purifier after a simple combination. Although this can remove heavy metals, pesticides, and organic matter, it cannot effectively sterilize because bacteria will enrich and multiply on such adsorption materials. In order to sterilize, the active material needs to be silvered or treated with chlorine or iodine, which will cause secondary pollution and the process is complicated. At present, the filter element of the water purification cup uses KDF as the filter material to achieve the purpose of sterilization, but KDF is easy to form blocks during use, which increases the pressure loss, thereby affecting the water flow rate and water purification effect, and the copper and zinc ion concentrations of the outlet water increase significantly. Moreover, the existing filter element is usually replaced as a consumable after use, which greatly increases the cost of use. In addition, since the filter element is an integral structure, the humidity in the filter material is high after use, which is easy to breed bacteria and cause secondary pollution.

DETAILED DESCRIPTION

[0015] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0016] Example: An ultrafiltration component for purifying a water cup, such as Figure 1-Figure 5As shown, multiple ultrafiltration filters 6, an upper cover 7 and a mounting shell 8 are provided. The bottom of the mounting shell 8 is provided with multiple filter bottom mounting holes 9 in a circular array along the axis. The filter bottom mounting holes 9 pass through the bottom of the mounting shell 8.
