By arranging the waterway lifting piece 3 and the shell main body 11 in a split manner, the waterway lifting piece 3, the valve core seat 2 and the shell 1 are separately manufactured and molded, and then the waterway lifting piece 3 and the valve core seat 2 are installed in the shell main body 11. Therefore, the shell 1 can be made of metal materials, and the waterway lifting piece 3 and the valve core seat 2 are respectively formed by plastic materials, so that the manufacturing cost and the process difficulty of the integral faucet are reduced.
Compared with the prior art, the water flow of the mixing water outlet hole 21 which is originally positioned below the valve core is lifted by arranging the lifting channel 31, so that the position of the water outlet pipe 12 on the shell body can be lifted, and the use space below the water outlet pipe 12 is increased.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
