Description

A self-filtered outlet pipe

technical field

The invention relates to the field of water filtration, in particular to a self-filtering water outlet pipe.

Background technique

Existing filter faucets usually include a seat body, a filter element disposed on the seat body, a valve core disposed on the seat body, and a water outlet pipe disposed on the seat body, such as a double-channel single-outlet water pipe disclosed in CN201610217194. Type water filter faucet, including a faucet body, a filter element, a water mixing valve, a direct drinking water valve and a water outlet pipe. There is a check valve at the intersection to allow the filtered water to pass into the outlet channel in one direction. The bottom end of the faucet body is the water inlet end. The water inlet end is equipped with a cold water inlet and a hot water inlet. A branch waterway is formed and extends to the mixing water valve end and the direct drinking water valve end respectively.

Existing people often have the chance of outdoor travel, but outdoor drinking water is often not clean, if can have a filtering device at this time, will guarantee people's drinking health. However, buying an outdoor filtering device in addition will appear redundant, because most of the time is not used, which causes waste, and it is necessary to find a special place to store it, causing a lot of unnecessary troubles.
