As shown in fig. 1 to 8, a four-way mixing valve according to a preferred embodiment of the present utility model includes a base 1, a mixing valve body 2 mounted on the base 1, and a first water inlet pipe 3, a second water inlet pipe 4, a first water outlet pipe 5 and a second water outlet pipe 6 connected to the base 1, respectively, (the mixing valve body 2 includes a valve core for mixing water, which is a specific structure not described in detail herein, as the prior art), the mixing valve body 2 is provided with a first water inlet 211, a second water inlet 212 and a water outlet 213, one end of the first water outlet pipe 5 connected to the base 1 is provided with a connection pipe 7 connected to the first water outlet pipe 5 and the water outlet 213, respectively, i.e. the water outlet 213 is connected to the first water outlet pipe 5 through the connection pipe 7, a slidable through-stop rod 71 is inserted into the connection pipe 7, a first end of the through-stop rod 71 extends into the first water outlet pipe 5, the first end of the through-stop rod 71 is provided with a first blocking block 72 for blocking the port of the connecting pipe 7, specifically, the first blocking block 72 blocks the port of the connecting pipe 7 connected with the first water outlet pipe 5, the size of the first blocking block 72 is smaller than that of the inner pipe of the first water outlet pipe 5, the second end of the through-stop rod 71 extends into the second water outlet pipe 6, the second end of the through-stop rod 71 is fixedly provided with a second blocking block 73 for blocking the second water outlet pipe 6, the second end of the through-stop rod 71 is provided with a water outlet hole 711 communicated with the water outlet 213 and the second water outlet pipe 6 respectively, a spring 74 is arranged between the second blocking block 73 and the end of the connecting pipe 7, and two ends of the spring 74 are connected with the connecting pipe 7 and the second blocking block 73 respectively.

It should be understood that the two parts in this embodiment are not limited to the two parts communicating directly, for example, the first water inlet 211 communicates with the first water inlet pipe 3, and since the water mixing valve body 2 is mounted on the base 1, in order to avoid the base 1 from obstructing the first water inlet 211 from communicating with the first water inlet pipe 3, the base 1 should be provided with through holes communicating with the first water inlet 211 and the first water inlet pipe 3, respectively, that is, the first water inlet 211 communicates with the first water inlet pipe 3 through the through holes.

The working principle of the embodiment is as follows: the first water inlet pipe 3 is connected with cold water, the second water inlet pipe 4 is connected with hot water, when the water mixing valve body 2 is in an open state, the water mixing valve body 2 can mix the cold water and the hot water according to an adjusted proportion, and then the cold water and the hot water are discharged from the water outlet 213, so that the water mixing function is realized; when the control valves of the first water outlet pipe 5 and the second water outlet pipe 6 are in an open state, the first blocking block 72 blocks the port of the connecting pipe 7, so that water discharged from the water outlet 213 cannot flow into the first water outlet pipe 5 through the connecting pipe 7, the first water outlet pipe 5 cannot discharge water, and the water outlet 711 is communicated with the water outlet 213 and the second water outlet pipe 6, so that water discharged from the water outlet 213 can flow into the second water outlet pipe 6 through the water outlet 711, and the second water outlet pipe 6 discharges water; when the control valve of the first water outlet pipe 5 is in an open state and the control valve of the second water outlet pipe 6 is in a closed state, water discharged from the water outlet 213 flows into the second water outlet pipe 6 through the water outlet hole 711, and as the control valve of the second water outlet pipe 6 is in a closed state, water in the second water outlet pipe 6 cannot be discharged and accumulated in the second water outlet pipe 6 pipeline, so that a thrust force close to the direction of the connecting pipe 7 is exerted on the second block 73, the second block 73 drives the through-stop rod 71 to slide in the direction close to the connecting pipe 7, and meanwhile, the spring 74 is compressed, at the moment, the first block 72 is separated from a port of the connecting pipe 7 due to the sliding of the through-stop rod 71, namely, the first block 72 is not used for blocking the port of the connecting pipe 7, and as the first block 72 is smaller than the size of the inner pipe of the first water outlet pipe 5, so that the water discharged from the water outlet 213 can flow into the first water outlet pipe 5 through the connecting pipe 7, namely, the first water outlet pipe 5 is discharged, and if the second block 73 drives the through-stop rod 71 to slide in the direction close to the connecting pipe 7, and if the second block 73 is opened, the second block 73 is restored to the original position, namely, the spring 74 is restored to the original position, namely, the first block 72 is restored to the original position.

In summary, when the control valve of the first water outlet pipe 5 and the control valve of the second water outlet pipe 6 are both in an open state (i.e. when the first water outlet pipe 5 and the second water outlet pipe 6 are both in an unblocked state), the first water outlet pipe 5 does not discharge water, and the second water outlet pipe 6 only needs to switch the second water outlet from the blocked state to the unblocked state when the control valve of the first water outlet pipe 5 is in an open state and the control valve of the second water outlet pipe 6 is in a closed state (i.e. when the first water outlet pipe 5 is in a unblocked state and the second water outlet pipe 6 is in a blocked state), the first water outlet pipe 5 can discharge water, i.e. the water outlet level of the second water outlet pipe 6 is higher than the water outlet level of the first water outlet pipe 5, so that the water outlet pressure and the flow rate of the second water outlet pipe 6 are ensured, and in actual operation is convenient when the first water outlet pipe 6 is in a blocked state, if the second water outlet pipe 6 is required to discharge water, and the second water outlet pipe 6 is not required to be normally switched.
