[0043] After the filter regulating valve is connected to the filter bottle body 60, Figure 4 and Figure 8 First, the external water source will enter the valve core assembly 7 through the water inlet joint 2 in turn, and then be divided into two paths. One water path passes through the water inlet 1 5, the clean water flow channel 9, and the water inlet 1 11 to enter the filter element for filtration, and the other water path passes through the water inlet 2 6, the water inlet flow channel 10, and the water inlet 2 12 to directly enter the filter chamber 61.

[0047] When the valve body and filter element need to be flushed, the valve stem 10 can be moved to the second position by pushing the push button 54 downward. Fig.10 , Fig.11 , Fig.16 At this time, the second clean water channel 15 is closed, and water will not flow out from the water outlet joint. The water can only enter the flushing outlet 17 through the control channel 20, and then flow out from the flushing outlet pipe 16 through the flushing flow channel 18.
