the top end of the outer body of the water faucet is provided with a water outlet hole, the bottom end of the outer body of the water faucet is respectively provided with a cold water hole communicated with a cold water pipe and a hot water hole communicated with a hot water pipe, and the cold water hole and the hot water hole are communicated with the water outlet hole through water channels;

the internal portion of tap forms the cavity outward, and the case is located in the cavity and the middle part be formed with gear engagement's rack, and the equal interval in both ends of case is formed with sprue and siphunculus, and the switch mounting just extends to and is connected with gear drive in the outside of the external body of tap to can transmit case reciprocating motion in the cavity when making to rotate switch drive gear, through switching the flow of sprue and siphunculus and water course cooperation control cold water or hot water.

Preferably, the number of the blocks is 1, the number of the through pipes is 2, and the 2 through pipes are arranged on two sides of the blocks.

Preferably, the axes of the block and the through pipe are parallel to the axes of the cold water hole and the hot water hole.

Preferably, the switch is sleeved with a detachable rotating handle.

Preferably, the diameter of the blocking piece is larger than that of the water channel, and the diameter of the through pipe is equal to that of the water channel.

Preferably, the rack is a plurality of racks arranged side by side.

According to the technical scheme, the faucet mainly comprises a faucet outer body, a valve core, a switch, a gear and a rack. When the switch of the water faucet is in a middle position, the water faucet is in a closed state, when the switch is in a left position, the valve core starts to move leftwards under the action of the gear, the water flow towards the left side is larger until the highest water flow is reached, the temperature of the water flow is constant at 35 degrees all the time in the leftward process, when the switch is moved from a middle gear to a right gear, the valve core starts to move rightwards under the action of the gear, and at the moment, the water temperature is approximately 50 degrees.
