[0033] The main body 1 includes a cavity 3, and a first pipe 4, a second pipe 5, a third pipe 6, and a fourth pipe 7 respectively connected to the cavity 3; the valve core 2 has two running water channels 11 on one side and a bypass water channel 12 on the other side; the valve core 2 is rotatably installed in the cavity 3; when the main body 1 is in the running state, rotating the valve core 2 connects the first pipe 4 and the second pipe 5 through one running water channel 11, and the third pipe 6 and the fourth pipe 7 are connected through the other running water channel 11; when the main body 1 is in the bypass state, rotating the valve core 2 connects the first pipe 4 and the fourth pipe 7 through the bypass water channel 12.

[0034] In actual use, the valve core 2 is rotatably installed inside the main body 1, so that rotating the valve core 2 can quickly switch between the running water channel 11 and the bypass water channel 12. In this device, the first pipe 4, one running water channel 11 and the second pipe 5 are raw water channels, and the third channel 6, another running channel 11 and the fourth channel 7 are clean water channels.

Figure 5As indicated by the arrow, rotating valve core 2 connects the first pipe 4 and the second pipe 5 through a running water channel 11, and the third pipe 6 and the fourth pipe 7 through another running water channel 11. At this time, raw water enters the running water channel 11 through the first pipe 4, and then connects to a water softener or ultrafiltration machine through the second pipe 5. After being filtered by the water softener or ultrafiltration machine, the raw water is filtered into purified water. The purified water is connected to the water softener or ultrafiltration machine through the third pipe 6, and enters the other running water channel 11 through the third pipe 6. Finally, the purified water enters the household pipe through the fourth pipe 7. This ensures that when the main body 1 is in operation, the raw water will not mix with the purified water. The raw water directly enters the filtration equipment through the bypass valve, and the filtered water enters the household pipe through the bypass valve.
