The second-level treated water obtained by further treating the first-level treated water through the second filter element 32 further flows from the fourth connecting pipe 24 and through the third communication channel 103 to the sixth connecting pipe 26 and is provided. As shown in the accompanying drawings FIG. 1B and FIG. 8BAs shown in the utility model water path controller (or the water path control valve 10) is in the parallel working position, the water to be treated can flow from the fifth connecting pipe 25, and respectively flow to the first connecting pipe 21 and the third connecting pipe 23 through the first conducting channel 1041, and respectively flow to the first filter element 31 and the second filter element 32, and the water to be treated is treated by the first filter element 31 and the second filter element 32, and the treated water is discharged through the second connecting pipe 22, the fourth connecting pipe 24 and the second conducting channel 1042 and flows to the sixth connecting pipe 26.

It can be understood that when the waterway control valve 10 is in the series working position, the second sealing part 1222 and the third sealing part 1223 prevent the first channel 1201 from being communicated with the third opening 1103, the fourth opening 1104, the second opening 1102 and the sixth opening 1106, and the first sealing part 1221 prevents the second channel 1202 from being communicated with the fourth opening 1104 and the sixth opening 1106.The valve core 12 of the waterway control valve 10 further comprises a fourth sealing part 1224 and a fifth sealing part 1225, the fourth sealing part 1224 and the fifth sealing part 1225 are respectively arranged on the main body part 121 and extend outward from the main body part 121, one end of the second channel 1202 is formed between the first sealing part 1221 and the fifth sealing part 1225, and the other end of the second channel 1202 is formed between the third sealing part 1223 and the fourth sealing part 1224.

[0051] As shown in the drawings, FIGS. 4A-8B Further, when the valve core 12 of the waterway control valve 10 is moved so that the waterway control valve 10 of the utility model is in the parallel working position, the second sealing part 1222 and the third sealing part 1223 are pressed against the inner wall of the valve body 11 between the fifth opening 1105 and the sixth opening 1106, the first sealing part 1221 is pressed against the inner wall of the valve body 11 outside the second opening 1102, and the first opening 1101, the third opening 1103 and the fifth opening 1105 are exposed to the second channel 1202, so that the second channel 1202 of the valve core 12 is respectively connected with the first opening 1101, the third opening 1103 and the fifth opening 1105 to form the first conduction channel 1041; the third channel 1203 of the valve core 12 is respectively connected with the second opening 1102, the fourth opening 1104 and the sixth opening 1106 to form the second conduction channel 1042. It can be understood that when the waterway control valve 10 is in the parallel working position, the first sealing part 1221 prevents the second channel 1202 from being connected with the second opening 1102, the fourth opening 1104 and the sixth opening 1106, and the second sealing part 1222 and the third sealing part 1223 prevent the first channel 1201 from being connected with the fifth opening 1105 and the sixth opening 1106. When the waterway control valve 10 of the utility model is in the parallel working position, further, the fourth sealing part 1224 is pressed against the inner wall of the valve body 11 outside the first opening 1101,

[0052] As shown in the drawings, FIGS. 4A-8BAs shown, preferably, the first channel 1201 and the third channel 1203 of the water route control valve 10 are both annular grooves around the main body 121 of the valve core 12, and the second channel 1202 extends between two ends of the main body 121. In other words, the first channel 1201 and the third channel 1203 are both formed on the outer surface of the valve core 12, and the main body 121 is a hollow cylinder. More preferably, the first channel 1201 of the water route control valve 10 is arranged to face the first opening 1101 and the fifth opening 1105 respectively when the water route control valve 10 is in the series working position, thereby forming the first communication channel 101; the second channel 1202 is arranged to face the second opening 1102 and the third opening 1103 respectively when the water route control valve 10 is in the series working position, thereby forming the second communication channel 102; the third channel 1203 is arranged to face the fourth opening 1104 and the sixth opening 1106 respectively when the water route control valve 10 is in the series working position, thereby forming the third communication channel 103; the second channel 1202 of the water route control valve 10 is arranged to face the first opening 1101, the third opening 1103 and the fifth opening 1105 respectively when the water route control valve 10 is in the parallel working position, thereby forming the first conduction channel 1041; the third channel 1203 is arranged to face the second opening 1102, the fourth opening 1104 and the sixth opening 1106 respectively when the water route control valve 10 is in the parallel working position, thereby forming the second conduction channel 1042. It can be understood that when the water route control valve 10 is in the parallel working position, the first channel 1201 is prevented from being connected to any of the first opening 1101, the second opening 1102, the third opening 1103, the fourth opening 1104, the fifth opening 1105 and the sixth opening 1106.

[0053] As shown in the drawings FIGS. 4A-8BAs shown, the second passage 1202 of the valve core 12 of the waterway control valve 10 has a first end opening 12021 and a second end opening 12022, wherein the fifth sealing part 1225 is arranged outside the first sealing part 1221, the first end opening 12021 is formed between the first sealing part 1221 and the fifth sealing part 1225, and the second end opening 12022 is formed between the third sealing part 1223 and the fourth sealing part 1224. Accordingly, when the waterway control valve 10 is in the series working position, the second end opening 12022 of the second passage 1202 of the valve core 12 of the waterway control valve 10 is communicated with the third opening 1103, and the first end opening 12021 of the second passage 1202 is communicated with the second opening 1102, so as to form the second communication passage 102; when the waterway control valve 10 is in the parallel working position, the first sealing part 1221 and the fifth sealing part 1225 are both pressed against the inner wall of the valve body 11. Therefore, although the second end opening 12022 of the second passage 1202 of the valve core 12 of the waterway control valve 10 is communicated with the first opening 1101, the third opening 1103 and the fifth opening 1105 when the waterway control valve 10 is in the parallel working position, the first end opening 12021 of the second passage 1202 is prevented from being communicated with the second opening 1102, the fourth opening 1104 and the sixth opening 1106 due to the first sealing part 1221 and the fifth sealing part 1225 being pressed against the inner wall of the valve body 11, so as to prevent water flow from the second end opening 12022 to the first end opening 12021 of the second passage 1202. Preferably, the first end opening 12021 is closed by the inner wall of the valve body 11 when the waterway control valve 10 is in the parallel working position.

[0054] As shown in the accompanying drawings FIGS. 4A-8BAs shown in the drawings, when the water route control valve 10 is in the parallel working position, the first channel 1201 of the valve core 12 is staggered with the first opening 1101, the third opening 1103 and the fifth opening 1105 of the valve body 11 respectively, and the second channel 1202 of the valve core 12 is staggered with the second opening 1102, the fourth opening 1104 and the sixth opening 1106 of the valve body 11 respectively, so that the valve body 11 and the valve core 12 of the water route control valve 10 no longer form the first communication channel 101, the second communication channel 102 and the third communication channel 103. At the same time, when the water route control valve 10 is in the parallel working position, the second end opening 12022 of the second channel 1202 of the valve core 12 is opposite to the first opening 1101, the third opening 1103 and the fifth opening 1105 of the valve body 11 of the water route control valve 10 respectively, and the third channel 1203 of the valve core 12 is opposite to the second opening 1102, the fourth opening 1104 and the sixth opening 1106 of the valve body 11.
