1. A double-water-output cylindrical integrated water purifier, comprising a base, a filter cylinder mounted on the base, and a filter element assembly located in the filter cylinder, wherein a raw water flow channel, a pure water flow channel and a waste water flow channel are disposed in the base, and a raw water inlet in communication with the raw water flow channel, a pure water outlet in communication with the pure water flow channel, and a waste water outlet in communication with the waste water flow channel are disposed at a side of the base respectively; a pure water production pipe of the filter element assembly is in communication with the pure water flow channel, and a first check valve for controlling water to flow into the pure water flow channel unidirectionally is disposed therebetween; a waste water outlet end face of the filter element assembly is in communication with the waste water flow channel; a control valve for controlling the raw water flow channel to be turned on and off based on a water pressure of the pure water flow channel is disposed in the base;
a clean water flow channel, a pure water branch flow channel and a waste water bypass flow channel are further disposed in the base, and a clean water outlet in communication with the clean water flow channel is disposed at a side of the base; the pure water flow channel communicates with the clean water flow channel via the pure water branch flow channel, and a second check valve for controlling water to flow into the clean water flow channel unidirectionally is disposed in the pure water branch flow channel; the waste water outlet end face is further communicated with the clean water flow channel via the waste water bypass flow channel, and a third check valve for controlling water to flow into the clean water flow channel unidirectionally is disposed in the waste water bypass flow channel, wherein the clean water flow channel is connected to the clean water pipe of a double-water-output faucet, and the pure water flow channel is connected to the pure water pipe of the double-water-output faucet;
wherein the base comprises a base body and a water channel cover plate fixed at the bottom of a cavity portion of the base, the water channel cover plate comprises a plate body and an upwardly-protruding water collection cavity integrally connected to the plate body, the water collection cavity is divided into a pure water through-cavity and a waste water cavity, the pure water through-cavity is in communication with the pure water flow channel, the pure water production pipe is inserted into the pure water through-cavity, and a first waste water outlet in communication with the waste water bypass flow channel and a second waste water outlet in communication with the waste water flow channel are disposed at the bottom of the waste water cavity respectively, a first waste water outlet pipe extends from the first waste water outlet, and a second waste water outlet pipe extends from the second waste water outlet;
wherein the pure water flow channel is formed from the pure water outlet, a pure water outlet flow channel, a first check valve cavity and a pure water outlet central pipe, sequentially, and the first check valve is disposed in the pure water outlet central pipe to enable water to flow from the pure water through-cavity to the pure water outlet flow channel unidirectionally;
wherein the pure water branch flow channel is formed from a second check valve cavity, a pure water inlet pipe, a pure water internal passage, a pure water outlet pipe and a first insertion cavity, sequentially, and the second check valve is disposed in the pure water inlet pipe to enable water to flow from the pure water outlet flow channel to the pure water internal passage unidirectionally;
wherein the clean water flow channel is formed from a clean water outlet flow channel and the clean water outlet that are communicated with each other;
wherein the waste water flow channel is formed from the second waste water outlet, the second waste water outlet pipe, a second insertion cavity, a waste water outlet flow channel and the waste water outlet, sequentially; and
wherein the waste water bypass flow channel is formed from the first waste water outlet, the first waste water outlet pipe and a third check valve cavity, sequentially, and the third check valve is disposed in the first waste water outlet pipe to enable the water to flow from the waste water cavity to the clean water outlet flow channel unidirectionally.
