Active carbon filter core

Abstract

The invention relates to an active carbon filter core. The active carbon filter core comprises a shell and an active carbon core, the surface of the shell is provided with a water inlet and a water outlet, a water inlet channel connected with the water inlet and a water outlet channel connected with the water outlet are arranged in the shell, the active carbon core is arranged in the shell and is connected between the water inlet channel and the water outlet channel, stopper plug for sealing the water inlet and the water outlet are respectively arranged in the water inlet and the water outlet, and an outlet water filtering layer and an outlet water bacteriostasis filtering layer arranged in the water outlet channel. The outlet water filtering layer and the outlet water bacteriostasis filtering layer arranged in the water outlet channel, so the active carbon filter core can prevent flow-out of active carbon powder in the active carbon filter core through the outlet water filtering layer, thereby blackening of water discharged from the water outlet channel, induced by carrying of the active carbon powder, is prevented, and other impurities can also be obstructed; and the outlet water bacteriostasis filtering layer is arranged, so entrance of bacteria to the water outlet channel is prevented.

Description

technical field [0001] The invention relates to an activated carbon filter element. Background technique [0002] Existing water purifiers are generally provided with multiple filter elements to achieve multi-stage filtration. Among them, the most commonly used ones are PP cotton filter element, ultrafiltration membrane filter element, RO membrane filter element, etc., but the water filtered by these filter elements is not good to drink. Therefore, it is necessary to set a filter element in the final stage of filtration. Improve the taste of water quality. Since the activated carbon filter element can directly remove residual chlorine, peculiar smell, color, chemical pollutants, etc. in the water quality, thereby improving the taste of the water quality and removing the peculiar smell of the water quality, so adding a post-installed activated carbon filter element in the final stage of filtration can be Absorbs odors enough to make water sweet and delicious.

AI Technical Summary

Problems solved by technology

Since the plug head is only a sheet about 3mm thick, it does not have a good guiding fit with the inner wall of the water inlet / outlet. At the same time, the spring is in smooth contact with its inner end surface, which makes the plug head easy to tilt and deviate, so that when the activated carbon filter element is not installed, The water inlet / outlet is prone to unclosed state, so that the inside of the filter element is polluted by air

Even, because the plug is tilted and stuck, when the filter element is connected to the water pipe, the water pipe and the water inlet / outlet cannot be inserted in place accurately, resulting in water leakage
