The bottom of the outlet installation groove 420 has a moving hole of the cylinder 150, and the diameter of the moving hole of the cylinder 150 is equal to the outer diameter of the cylinder 150, so that the outlet hole 151 of the cylinder 150 can be located in the mixing chamber 400 or only in the outlet channel 300 to connect or separate the mixing chamber 400 and the outlet channel 300.

In a preferred embodiment, as shown in fig. 1, a protrusion 510 is provided at the connection between the housing 500 and the transmission rod 160, the protrusion 510 protrudes out of the sidewall of the housing 500, a sealing sheet 520 is provided in the protrusion 510, and the transmission rod 160 passes through the sealing sheet 520. Thereby avoiding the occurrence of water leakage and the like and improving the reliability of the water mixing valve 1.

In a preferred embodiment, as shown in fig. 1, the control unit 100 further includes a handle 170, and the handle 170 is connected to the end of the transmission rod 160 extending out of the housing 500. Thereby facilitating user control of the movement of the drive link 160.

In particular embodiments, the handle 170 may be shaped as desired to facilitate adjustment by being held by a user.

The embodiment of the invention also provides a water heater, which comprises the water mixing valve 1. The mixing valve 1 at least comprises a water inlet passage 200 for inlet of hot water, a water inlet passage 200 for inlet of cold water and a water outlet passage 300 for outlet of water.

While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
