When the instant water outlet system works, the instant water outlet system is installed on wading equipment such as a water dispenser and the like, when the wading equipment such as the water dispenser and the like needs water purification, the water purifier 600 starts to work, purified water enters the left cavity 12 from the purified water inlet 14 of the water flow distributor 100, the water distribution valve core 4 moves towards the purified water outlet 51 (moves leftwards) under the action of pressure difference, and a gap for purified water to flow into the separation hole 111 is formed between the water distribution valve core 4 and the separation platform 11. The purified water is divided into two flow directions, one flow direction enters the left flow passage 42 of the water diversion valve core 4 through the first through hole 21 and the third through hole 44 and then flows to the quantitative pressure suction electromagnetic valve 200, the other flow direction enters the right flow passage 43 of the water diversion valve core 4 through the second through hole 22 and the fourth through hole 45 and then flows to the mixed water outlet 15 through the partition hole 111, the one-way valve 7 and the fifth through hole 33, redundant purified water flows to the mixed water outlet 15, the water outlet ratio of the two flows of purified water depends on the water amount required by wading equipment such as a drinking fountain, when the using amount of the wading equipment such as the drinking fountain is small, the moving stroke of the water diversion valve core 4 is small, the more purified water flows into the mixed water outlet 15, when the flow required by the wading equipment such as the drinking fountain is large, the moving stroke of the water diversion valve core 4 is large, at the moment, the gap between the water diversion valve core 4 and the partition table 11 is small, and the less purified water flows into the mixed water outlet. When wading equipment such as a water dispenser stops working, the water diversion valve core 4 blocks the separation hole 111 under the action of the first spring 8, the mixed water outlet 15 is closed, and purified water is ensured not to flow out any more.
When the redundant purified water flows into the mixed water outlet 15 through the check valve 7, the redundant purified water and the raw water flowing in from the raw water inlet 32 are mixed and enter the water purifier 600, the differential pressure valve core 6 is used for controlling the flow of the raw water to supply the water purifier 600, when the pressure of the purified water entering the mixed water outlet 15 is small, the differential pressure valve core 6 is opened maximally under the pressure of the raw water, when the pressure of the purified water entering the mixed water outlet 15 is increased, the differential pressure valve core 6 moves (moves rightwards) towards the raw water inlet 32, the differential pressure valve core 6 tends to gradually block the guide hole 31, the gap for the raw water to flow in is smaller and smaller, and the raw water inlet amount is reduced.

In order to fix the pneumatic diaphragm 98, the outer edge of the lower cover 93 has a circular groove 931 with an upward opening, the outer edge of the lower end of the pneumatic diaphragm 98 is clamped in the groove 931, and the pneumatic diaphragm 98 is clamped between the upper end of the lower cover 93 and the lower end of the valve body 91. The pneumatic diaphragm 98 is made of soft material, preferably silica gel, so that the middle part of the pneumatic diaphragm 98 can move upward when the water sucking port 912 is sucked by the water pump.
The lower end of the ejector pin 99 is fixed at the central position of the upper end of the air pressure diaphragm 98, the upper end of the ejector pin 99 extends into the central flow guide hole 951, a gap for water to pass through is reserved between the ejector pin 99 and the inner wall of the central flow guide hole 951, and the ejector pin 99 upwards pushes the valve rod 96 after moving upwards so that the opening at the upper end of the central flow guide hole 951 is opened.

The principle of the 'mechanical' control of the quantitative pressure suction electromagnetic valve is as follows: water flows in from the valve body water inlet 911, because the central flow guide hole 951 of the hydraulic diaphragm 95 is blocked by the valve rod 96, the raw water with pressure is choked, the water cannot flow to the suction water inlet 912 through the hydraulic diaphragm 95, and after the suction water inlet 912 is sucked and pressed by the water pump, the air pressure diaphragm 98 drives the ejector pin 99 to move upwards, the ejector pin 99 pushes the valve rod 96 upwards, so that the central flow guide hole 951 is opened, the pressures at the upper end and the lower end of the hydraulic diaphragm 95 are balanced, and the water can smoothly flow out from the suction water inlet 912. When the water pump stops sucking pressure, the ejector pin 99 is instantaneously reset to the initial state under the action of the air pressure diaphragm 98, the valve rod 96 blocks the central flow guide hole 951 again through the elastic force of the iron core spring 97, and the central flow guide hole 951 of the water pressure diaphragm 95 is closed.
The principle of 'electronic' control of the quantitative pressure suction electromagnetic valve is as follows: when the solenoid valve 92 is powered on, the valve rod 96 is lifted by means of electromagnetic force, so that the central flow guide hole 951 is opened, and after the solenoid valve 92 is powered off, the valve rod 96 resets under the action of the elastic force of the iron core spring 97, and the central flow guide hole 951 is closed.
