DETAILED DESCRIPTION

[0029] In order to more intuitively and completely understand the technical solution of the present invention, a non-limiting feature description is now provided in conjunction with the accompanying drawings of the present invention as follows:

[0030] Embodiment 1: Figure 1 — Figure 4As shown, the water flow distributor comprises a main pipe 1, a partition 11 is provided in the middle of the main pipe 1, the partition 11 has a partition hole 111 which passes through the left and right sides, and the inside of the main pipe 1 is divided into a left cavity 12 and a right cavity 13 by the partition 11, the left cavity 12 and the right cavity 13 are both connected with the partition hole 111, a water distribution sleeve 2 extending to the left and right is installed in the left cavity 12, a water inlet sleeve 3 extending to the left and right is installed in the right cavity 13, and a clean water inlet 14 connected with the water distribution sleeve 2 and a mixed water outlet 15 connected with the water inlet sleeve 3 are provided at the top of the main pipe 1;

[0031] A water diversion valve core 4 that can move left and right is installed in the water diversion sleeve 2. The water diversion valve core 4 is connected to the water diversion sleeve 2. The right end of the water diversion valve core 4 is used to block the left end opening of the partition hole 111. The left end of the water diversion sleeve 2 is connected to a water outlet end cover 5 that is connected to the water diversion valve core 4. The water outlet end cover 5 has a clean water outlet 51.

[0032] The water inlet sleeve 3 has a guide hole 31 that runs through from left to right. A pressure differential valve core 6 that can move left to right and is used to block the guide hole 31 is installed in the water inlet sleeve 3. The pressure differential valve core 6 is connected to the water inlet sleeve 3. The right end of the water inlet sleeve 3 has a raw water inlet 32 ​​that is connected to the guide hole 31.

[0033] like Figure 2 As shown, a one-way valve 7 is installed in the partition table 11, and the one-way valve 7 is connected with the partition hole 111 and the water inlet sleeve 3. The function of the one-way valve 7 is to prevent water from flowing back from the right cavity 13 to the left cavity 12.

[0034] like Figure 2 and Figure 3 As shown, the top of the water diversion sleeve 2 has a first through hole 21 and a second through hole 22 connected to the clean water inlet 14, a diverter plate 41 is provided in the middle of the water diversion valve core 4, and the inside of the water diversion valve core 4 is divided by the diverter plate 41 to form a left flow channel 42 and a right flow channel 43, the upper end of the water diversion valve core 4 has a third through hole 44 connected to the left flow channel 42 and the first through hole 21, and a fourth through hole 45 connected to the right flow channel 43 and the second through hole 22, the left flow channel 42 is connected to the clean water outlet 51, and the second through hole 22 is connected to the partition hole 111.

[0035] like Figure 2 As shown, a first spring 8 extending leftward and rightward is installed between the right end of the water outlet cover 5 and the left end of the water diversion valve core 4.

[0036] like Figure 2 As shown, the upper end of the water inlet sleeve 3 has a fifth through hole 33 and a sixth through hole 34 which are connected to the mixing water outlet 15 , and the sixth through hole 34 is connected to the guide hole 31 .

[0037] like Figure 2As shown, a second spring 9 is installed between the right end of the one-way valve 7 and the left end of the differential pressure valve core 6, and the right end of the differential pressure valve core 6 is used to block the guide hole 31. The guide hole 31 is located on the right side of the differential pressure valve core 6.

[0038] During operation, the water flow distributor is connected to a large-flow water purifier with a water pump (not shown in the figure). The specific connection conditions are: the purified water outlet of the water purifier is connected to the purified water inlet 14 of the water flow distributor, the raw water (not shown in the figure) is connected to the raw water inlet 32 ​​of the water flow distributor, the mixing outlet 15 on the water flow distributor is connected to the raw water inlet of the water purifier, and the purified water outlet 51 of the water flow distributor is connected to water-related equipment such as ice makers, beverage dispensers, and pipeline machines (not shown in the figure).

[0039] When water-related equipment such as a drinking fountain requires water purification, the high-flow water purifier with a water pump starts to work, and the purified water enters the left cavity 12 from the purified water inlet 14 of the water flow distributor. Under the action of the pressure difference, the water diversion valve core 4 moves toward the purified water outlet 51 (moves to the left), and a gap is formed between the water diversion valve core 4 and the partition table 11 for purified water to flow into the partition hole 111. The purified water flows in two directions. One path of purified water enters the left flow channel 42 of the water diverter valve core 4 through the first through hole 21 and the third through hole 44 and then flows to water-related equipment such as a drinking machine. The other path of purified water enters the right flow channel 43 of the water diverter 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. The excess purified water flows to the mixed water outlet 15. The water output ratio of the two paths of purified water depends on the amount of water required by water-related equipment such as a drinking machine. When the amount of water used by water-related equipment such as a drinking machine is small, the stroke of the water diverter valve core 4 is small, and more purified water flows into the mixed water outlet 15. When the water-related equipment such as a drinking machine requires a larger flow rate, the stroke of the water diverter valve core 4 becomes larger. At this time, the gap between the water diverter valve core 4 and the partition table 11 becomes smaller, and less purified water flows into the mixed water outlet. When the water-related equipment such as the drinking fountain stops working, the water-dividing valve core 4 blocks the separation hole 111 under the action of the first spring 8, closes the mixed water outlet 15, and ensures that the clean water no longer flows out.

[0040] When excess clean water flows into the mixing outlet 15 through the one-way valve 7, it will be mixed with the raw water flowing in from the raw water inlet 32 ​​and enter the water purifier. The pressure differential valve core 6 is used to control the flow rate of raw water to supply the needs of the water purifier. When the pressure of clean water entering the mixing outlet 15 is relatively low, the pressure differential valve core 6 opens to the maximum under the pressure of the raw water. When the pressure of clean water entering the mixing outlet 15 increases, the pressure differential valve core 6 moves toward the raw water inlet 32 ​​(moves to the right), and the pressure differential valve core 6 tends to gradually block the guide hole 31. The gap for raw water to flow in will become smaller and smaller, causing the amount of raw water entering to decrease.

[0041] Embodiment 2: Figure 5 — Figure 7As shown, the water flow distributor comprises a main pipe 1, wherein the main pipe 1 has a partition table 11, wherein the partition table 11 has a partition hole 111 which passes through the left and right sides, and the inside of the main pipe 1 is divided into a left cavity 12 and a right cavity 13 by the partition table 11, wherein the left cavity 12 and the right cavity 13 are both connected to the partition hole 111, wherein a water diversion valve core 4 which can move left and right is installed in the left cavity 12, wherein a pressure difference valve core 6 which can move left and right is installed in the right cavity 13, wherein a clean water inlet pipe 80 with a clean water inlet 14 and a mixed water outlet pipe 90 with a mixed water outlet 15 are fixed to the top of the main pipe 1, wherein the clean water inlet 14 is connected to the water diversion valve core 4;

[0042] The right end of the water diversion valve core 4 is used to block the left end opening of the partition hole 111, and the left end of the main pipe 1 is installed with a water outlet sleeve 60 with a clean water outlet 51;

[0043] The right cavity 13 of the main pipe 1 has a guide hole 31 that can be connected to the mixing water outlet 15 . The right end of the main pipe 1 is equipped with a water inlet sleeve 70 with a raw water inlet 32 ​​, and the raw water inlet 32 ​​is connected to the guide hole 31 .

[0044] like Figure 5 As shown, a one-way valve 7 is installed in the partition platform 11 , and the one-way valve 7 is communicated with the partition hole 111 .

[0045] like Figure 5 and Figure 6 As shown, the top of the main pipe 1 has a first through hole 21 and a second through hole 22 connected to the clean water inlet 14 and the left cavity 12, a diverter plate 41 is provided in the middle of the water diverter valve core 4, and the inside of the water diverter valve core 4 is divided by the diverter plate 41 to form a left flow channel 42 and a right flow channel 43, the upper end of the water diverter valve core 4 has a third through hole 44 connected to the left flow channel 42 and the first through hole 21, and a fourth through hole 45 connected to the right flow channel 43 and the second through hole 22, the left flow channel 42 is connected to the clean water outlet 51, and the second through hole 22 is connected to the partition hole 111.

[0046] A first spring 8 extending leftward and rightward is installed between the right end of the water outlet sleeve 60 and the left end of the water diversion valve core 4;

[0047] The top of the main pipe 1 has a fifth through hole 33 and a sixth through hole 34 connected to the mixing water outlet 15 and the right cavity 13, and the sixth through hole 34 is connected to the guide hole 31;

[0048] A second spring 9 is installed between the right end of the one-way valve 7 and the left end of the differential pressure valve core 6 . The right end of the differential pressure valve core 6 is used to block the guide hole 31 .

[0049] During operation, the water flow distributor is connected to a large-flow water purifier with a water pump (not shown in the figure). The specific connection conditions are: the purified water outlet 51 of the water purifier is connected to the purified water inlet 14 of the water flow distributor, the raw water (not shown in the figure) is connected to the raw water inlet 32 ​​of the water flow distributor, the mixing outlet 15 on the water flow distributor is connected to the raw water inlet 32 ​​of the water purifier, and the purified water outlet 51 of the water flow distributor is connected to water-related equipment such as ice makers, beverage dispensers, and pipeline machines (not shown in the figure).

[0050] When water-related equipment such as a drinking fountain requires water purification, the high-flow water purifier with a water pump starts to work, and the purified water enters the left cavity 12 from the purified water inlet 14 of the water flow distributor. Under the action of the pressure difference, the water diversion valve core 4 moves toward the purified water outlet 51 (moves to the left), and a gap is formed between the water diversion valve core 4 and the partition table 11 for purified water to flow into the partition hole 111. The purified water flows in two directions. One path of purified water enters the left flow channel 42 of the water diverter valve core 4 through the first through hole 21 and the third through hole 44 and then flows to water-related equipment such as a drinking machine. The other path of purified water enters the right flow channel 43 of the water diverter 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. The excess purified water flows to the mixed water outlet 15. The water output ratio of the two paths of purified water depends on the amount of water required by water-related equipment such as a drinking machine. When the amount of water used by water-related equipment such as a drinking machine is small, the stroke of the water diverter valve core 4 is small, and more purified water flows into the mixed water outlet 15. When the water-related equipment such as a drinking machine requires a larger flow rate, the stroke of the water diverter valve core 4 becomes larger. At this time, the gap between the water diverter valve core 4 and the partition table 11 becomes smaller, and less purified water flows into the mixed water outlet. When the water-related equipment such as the drinking fountain stops working, the water-dividing valve core 4 blocks the separation hole 111 under the action of the first spring 8, closes the mixed water outlet 15, and ensures that the clean water no longer flows out.

[0051] When excess clean water flows into the mixing outlet 15 through the one-way valve 7, it will be mixed with the raw water flowing in from the raw water inlet 32 ​​and enter the water purifier. The pressure differential valve core 6 is used to control the flow rate of raw water to supply the needs of the water purifier. When the pressure of clean water entering the mixing outlet 15 is relatively low, the pressure differential valve core 6 opens to the maximum under the pressure of the raw water. When the pressure of clean water entering the mixing outlet 15 increases, the pressure differential valve core 6 moves toward the raw water inlet 32 ​​(moves to the right), and the pressure differential valve core 6 tends to gradually block the guide hole 31. The gap for raw water to flow in will become smaller and smaller, causing the amount of raw water entering to decrease.

[0052] The water flow distributor provided by the present invention can utilize excess purified water, thereby solving the problem of repeated starting when a water-related device with a small water flow rate is connected to a water purifier with a large water flow rate and a water pump, thereby protecting the service life and stability of the water purifier.
