The first valve body 110 is connected to a first control component 300, a second control component 400, a first check component 700, and a second check component 800.

[0027] like Figure 6 As shown, the first channel 111 connects the tap water inlet A1 and the first filter cartridge interface B1. One end of the fourth channel 114 is the third filter cartridge interface B3, and the other end is connected to the seventh channel 117. The end of the seventh channel 117 away from the fourth channel 114 is the first connection interface A6.

[0028] like Figure 7 As shown, the second channel 112 is connected to the fifth channel 115 and the second filter element interface B2. One end of the fifth channel 115 is closed and the other end is connected to the eighth channel 118. One end of the eighth channel 118 is provided with the first water pump interface A5 and the other end is connected to the sixth channel 116.

[0029] A second control component connection structure 123 is provided between the eighth channel 118 and the sixth channel 116. A second control component 400 is connected to the second control component connection structure 123 to control the on / off state of the eighth channel 118 and the sixth channel 116. Specifically, the second control component 400 is a solenoid valve control component. A second water-sealing seat 124 is provided inside the second control component connection structure 123. The second water-sealing seat 124 is an annular protrusion extending along the X-axis direction. Its inner cavity communicates with the eighth channel 118, and its outer cavity communicates with the sixth channel 116. The second control component 400 cooperates with the second water-sealing seat 124, and controls the on / off state of the eighth channel 118 and the sixth channel 116 by controlling the on / off state of the inner and outer cavities of the second water-sealing seat 124. When the second control component 400 is de-energized, the eighth channel 118 and the sixth channel 116 are not connected, and water flows out of the first outlet A2. When the second control component 400 is energized, the eighth channel 118 and the sixth channel 116 are connected.

[0030] The eighth channel 118 includes a first check valve section 1181 and a second check valve section 1182 along the X-axis. The inner cavity of the second water-sealing seat 124 communicates with the first check valve section 1181. The fifth channel 115 communicates with the second check valve section 1182. The second check valve assembly 800 is located within the first check valve section 1181, restricting water flow to only unidirectionally enter the second check valve section 1182 from the first check valve section 1181. Specifically, as shown... Figure 9As shown, the second check assembly 800 includes a second valve seat 810, a second valve core 820, a second spring 830, and a second valve core seat 840. The second valve seat 810 and the second valve core seat 840 are both fixed within the eighth channel 118, located near the first check section 1181 and near the second check section 1182, respectively. The second spring 830 connects the second valve core 820 and the second valve core seat 840. One end of the second valve core 820 is a sealing end, and the other end is a connecting end. The connecting end of the second valve core 820 is radially limited to the second... The valve core 820 slides within and relative to the valve seat 840. When the water pressure in the first check section 1181 is high, the water flow in the inner cavity of the second sealing seat 124 pushes the second valve core 820 to move and compresses the second spring 830, allowing water to flow from the first check section 1181 into the second check section 1182. When the water pressure in the first check section 1181 is low or the water pressure in the second check section 1182 is high, the second spring 830 resets, and the sealing end of the second valve core 820 seals with the second valve seat 810, preventing water from flowing from the second check section 1182 into the first check section 1181.

[0031] like Figure 6 As shown, the third channel 113 includes a first inlet section 1131 and a first outlet section 1132 along the Z-axis. The end of the first outlet section 1132 away from the first inlet section 1131 is the second outlet A3. A first control component connection structure 121 is provided between the first inlet section 1131 and the first outlet section 1132. A first control component 300 is connected to the first control component connection structure 121 to control the on / off state of the first inlet section 1131 and the first outlet section 1132. Specifically, the first control component 300 is a solenoid valve control component. The first control component connection structure 121 contains a first water-sealing seat 122, which is an annular protrusion extending along the X-axis. Its inner cavity communicates with the first water outlet section 1132, and its outer cavity communicates with the first water inlet section 1131. The first control component 300 cooperates with the first water-sealing seat 122, and controls the connection and disconnection of the first water inlet section 1131 and the first water outlet section 1132 by controlling the opening and closing of the inner and outer cavities of the first water-sealing seat 122. When the first control component 300 is de-energized, the first water inlet section 1131 and the first water outlet section 1132 are not connected. When the first control component 300 is energized, the eighth channel 118 and the sixth channel 116 are connected, and water flows out of the second water outlet A3.

[0032] like Figure 8 As shown, the sixth channel 116 includes, along the Y-axis, a first water-sealing seat 122 outer cavity, a connecting flow section 1161, a second water-sealing seat 124 outer cavity, and a third check valve section 1162 connected in sequence. The end of the first water-sealing seat 122 outer cavity away from the connecting flow section 1161 is a reserved port A4.

[0033] After the water inlet at the fourth filter element interface B4 enters the outer cavity of the first water seal seat 122 through the first water inlet section 1131, it can flow out from the reserved port A4 or enter the outer cavity of the second water seal seat 124 through the connecting flow section 1161.

[0034] The third check valve section 1162 is connected to a ninth channel 119 extending along the Z-axis. The first outlet A2 is located at the end of the ninth channel 119 away from the third check valve section 1162. The first check valve assembly 700 is located between the third check valve section 1162 and the outer cavity of the second water seal seat 124, restricting water flow to enter the third check valve section 1162 only unidirectionally from the outer cavity of the second water seal seat 124. Specifically, as shown... Figure 10 As shown, the first check valve assembly 700 includes a first valve seat 710, a first valve core 720, a first spring 730, and a first valve core seat 740. The first valve seat 710 and the first valve core seat 740 are both fixed within the third check valve section 1162, located near and away from the outer cavity of the second water seal seat 124, respectively. The first spring 730 connects the first valve core 720 and the first valve core seat 740. One end of the first valve core 720 is a sealing end, and the other end is a connecting end. The diameter of the connecting end of the first valve core 720 is... The valve core 720 is located within and slides relative to the first valve core seat 740. When the water pressure in the outer cavity of the second water seal seat 124 is large, the water flow in the outer cavity of the second water seal seat 124 pushes the first valve core 720 to move and compresses the first spring 730, and the water flow enters the third check section 1162. When the water pressure in the outer cavity of the second water seal seat 124 is small or the water pressure in the third check section 1162 is large, the first spring 730 is reset, the sealing end of the first valve core 720 is sealed with the first valve seat 710, and the water flow cannot enter the outer cavity of the second water seal seat 124 from the third check section 1162.

[0035] A pressure switch 900 is provided at the end of the third check section 1162 away from the outer cavity of the second water seal seat 124. The pressure switch 900 senses the pressure change of the medium in the measured third check section 1162 through its internal elastic element (such as a spring tube, diaphragm, etc.). When the pressure reaches a preset threshold, it triggers an electrical signal output, thereby controlling the start and stop of the equipment or issuing an alarm.

[0036] like Figures 11-13 As shown, the second valve body 210 includes an inlet channel 211, a pure water outlet channel 212, a wastewater outlet channel 213, a wastewater discharge channel 215, and a wastewater flow channel 214 extending along the Z-axis. The second valve body 210 is provided with a third control component 500 and a fourth control component 600.

A third control component 500 is connected to the third control component connection structure 221 to control the opening and closing of the wastewater flow channel 214 and the wastewater outlet channel 213. Specifically, the third control component 500 is a solenoid valve control component. The third control component connection structure 221 contains a third sealing seat 222, which is an annular protrusion arranged along the Y-axis. Its inner cavity communicates with the end of the wastewater flow channel 214, and its outer cavity communicates with the end of the wastewater outlet channel 213. The third control component 500 cooperates with the third sealing seat 222, and controls the opening and closing of the wastewater flow channel 214 and the wastewater outlet channel 213 by controlling the opening and closing of the inner and outer cavities of the third sealing seat 222. When the third control component 500 is de-energized, the wastewater flow channel 214 is not connected to the wastewater outlet channel 213. When the third control component 500 is energized, the wastewater in the wastewater outlet channel 213 enters the wastewater flow channel 214.

[0039] A fourth control component connection structure 223 is provided near the closed end of the wastewater flow channel 214. A fourth control component 600 is connected to the fourth control component connection structure 223 to control the opening and closing of the wastewater flow channel 214 and the wastewater discharge channel 215. Specifically, the fourth control component 600 is a solenoid valve control component. A fourth water-sealing seat 224 is provided within the fourth control component connection structure 223. The fourth water-sealing seat 224 is an annular protrusion arranged along the Y-axis. Its inner cavity communicates with the end of the wastewater discharge channel 215, and its outer cavity communicates with the end of the wastewater flow channel 214. The fourth control component 600 cooperates with the fourth water-sealing seat 224, and controls the opening and closing of the wastewater flow channel 214 and the wastewater discharge channel 215 by controlling the opening and closing of the inner and outer cavities of the fourth water-sealing seat 224. When the fourth control component 600 is de-energized, the wastewater flow channel 214 and the wastewater discharge channel 215 are not connected. When the fourth control component 600 is energized, wastewater from the wastewater flow channel 214 enters the wastewater discharge channel 215 and connects to the wastewater pipeline through the wastewater outlet C3. The fourth control component 600 can control the amount of wastewater passing through the wastewater outlet C3 by controlling the flow rate of the wastewater flow channel 214 and the wastewater discharge channel 215.
