The water duct 110 includes a second water inlet waterway 112, a first water inlet waterway 111, and a water outlet waterway 113. The first water inlet passage 111 and the second water inlet passage 112 are water inlet passages having different temperatures. The first water inlet path 111 is a cold water path, and the second water inlet path 112 is a hot water path. Alternatively, the first water inlet channel 111 is a hot water channel, and the second water inlet channel 112 is a cold water channel, which is not limited herein. The water discharge passage 113 may be only cold water, only hot water, or mixed water of a predetermined temperature at which cold water and hot water are mixed.

The water mixing assembly 130 is arranged on the water pipe 110 and is located between the first water inlet waterway 111, the second water inlet waterway 112 and the water outlet waterway 113, so that the temperature of the mixed water of cold water and hot water entering the water mixing device 100 is constant, the constant temperature fluctuation caused by temperature impact and flow change can be effectively reduced, and the experience and comfort of bathing and washing of a user are improved.

Referring to fig. 3 to 8, the mixing assembly 130 includes a mixing valve core 132 and a mixing base 131. The mixing valve core 132 and the mixing base 131 cooperate to form the mixing assembly 130.

As such, the mixed water entering from the water pipe 110 may be output through the mixed water outlet 1314 and flow into the outlet waterway 113 after passing through the water mixing assembly 130.

The water mixing base 131 is arranged in the water pipe 110, the water mixing base 131 is circumferentially provided with a flow guiding rib 1315, the water pipe 110 comprises a flow guiding part 113 which is spaced from and opposite to a part of the mixed water outlet 1314, the flow guiding rib 1315 and the flow guiding part 113 form an initial section 1316 of the water outlet waterway 113, and the mixed water outlet 1314 is communicated with the initial section of the water outlet waterway 113.

The flow guiding ribs 1315 are obliquely arranged along the outer circumferential surface 1317 of the mixing base 131. Thus, the volume of the initial section 1316 of the water outlet waterway 113 formed by the diversion rib 1315 and the water pipe 110 is larger, and more mixed water can flow out of the water outlet waterway 113.

Referring to fig. 4 to 6, the mixing base 131 includes a protrusion 1318, the protrusion 1318 extends from the sidewall of the mixing base 131 along the axial direction of the mixing base 131, the protrusion 1318 encloses a first channel 1311, and the first channel 1311 is in communication with the first water inlet channel 111 along the axial direction of the mixing base 131. It is understood that, as shown in fig. 3, the first passage 1311 may be formed after the protrusion 1318 of the mixing base 131 is engaged with the water pipe 110, so that the water of the first water inlet waterway 111 enters the first passage 1311.

It can be understood that when the temperature or the flow rate of the cold water or the hot water changes greatly, if the water mixing base 131 is not provided, a certain time is required for the temperature sensing device in the water mixing valve element 132 to change shape, action and constant temperature, and the fluctuation of the outlet water temperature is caused in this time. After the water mixing base 131 is added, the small-section special-shaped water outlet flow channel in the water mixing base 131 can play a role in buffering mixed water.

Referring again to fig. 3, the mixing assembly 130 includes the mixing adjustment knob 133, and the other end 1327 of the mixing valve element 132 includes a connecting portion 1328, and the mixing adjustment knob 133 is fixedly connected to the connecting portion 1328.
