Further, as shown in fig. 1 and 3, the water purifier wastewater reuse waterway structure further includes a first drainage assembly 6, and the wastewater storage tank 5 is communicated with the mixed water channel 42 through the first drainage assembly 6.

Specifically, the first flow guiding assembly 6 includes a first ejector 61, the first ejector 61 has a water inlet 611 communicating with the first raw water pipeline 1, a water outlet 612 communicating with the mixed water channel 42, and a siphon port 613 communicating with the waste water storage tank 5, and a mixing chamber communicating with the water inlet 611, the water outlet 612, and the siphon port 613 is provided in the first ejector 61.

The jet device is mainly applied to the occasion of gas-liquid mixing, but has good jet effect on the mixing of liquid and liquid, and has the advantages of simple structure, safe operation, low cost, quick effect, no power consumption and the like. Under the high-speed mobile state of raw water in the first former water pipeline 1, can locate to form the negative pressure at first ejector 61, waste water in the first ejector 61 under the negative pressure state can automatic siphon waste water storage water tank 5, and the siphon ability is stronger, avoids waste water can't get into mixed water runner 42 because of water pressure is not enough, consequently, need not additionally to set up accessories such as water pump, motor with waste water pump sending to mixed water runner 42, has reduced accessory cost and use cost. In addition, the setting of mixing chamber in the first ejector 61 can make waste water and the raw water of concentration difference flow out after the intensive mixing, improves injection strength.

As a preferred example of the present embodiment, the first ejector 61 is further optimized in that, as shown in fig. 2 and 3, the first ejector 61 includes a main flow passage 614 and a siphon flow passage 615, the water inlet 611 and the water outlet 612 are respectively disposed at both ends of the main flow passage 614, one end of the siphon flow passage 615 is connected to the main flow passage 614, and the siphon port 613 is disposed at the other end. The mixing chamber is mainly disposed in the main flow channel 614, and the waste water siphoned by the siphon flow channel 615 enters the main flow channel 614 to be mixed with the raw water to form mixed water for discharge.

In addition, an included angle α between a central axis of the siphon runner 615 and a central axis of the main runner 614 satisfies: alpha is more than or equal to 25 degrees and less than or equal to 35 degrees, preferably, an intermediate value can be selected, namely, the included angle alpha is 30 degrees, the optimal jet effect can be ensured, the phenomenon that the siphon flow channel 615 is too narrow due to too small included angle, so that the siphon waste water quantity is too small or the water seal cannot be carried away due to the formation of water seal on the siphon flow channel 615 caused by too large included angle is avoided, and the utilization rate of the waste water at the water outlet faucet 4 is improved.

A further optimization of the first ejector 61 is that the inner diameter of the siphon flow channel 615 is one third of the inner diameter of the main flow channel 614.

The siphon flow channel 615 has an excessively large diameter, which is likely to cause insufficient negative pressure to cause a siphon effect, and the siphon flow channel 615 has an excessively small diameter, which is likely to cause a siphon failure and thus a too small waste water flow rate. The inner diameter of the siphon flow channel 615 is one third of the inner diameter of the main flow channel 614 (allowing machining error in a proper range), so that the siphon effect can be ensured, and the flow of the wastewater can be properly mixed with the raw water.

Further, as shown in fig. 4, the first check valve 62 includes a valve body 621 having a flow guide channel, and a valve core 622 disposed in the flow guide channel, wherein the valve core 622 has a first position for blocking the flow guide channel and a second position for conducting the flow guide channel (the valve core 622 is shown in the first position in fig. 4), and when the waste water in the waste water storage tank 5 flows to the first ejector 61, the valve core 622 moves from the first position to the second position under the hydraulic pressure of the waste water.

When waste water in the waste water storage tank 5 flows to the first ejector 61, the valve core 622 moves to the second position that makes the water conservancy diversion passageway switch on from the first position of cutting off the water conservancy diversion passageway under the water pressure effect of waste water, namely first check valve 62 is automatic valve, and the water pressure of waste water can back open valve core 622, and play tap 4 and close, and water pressure disappears, and valve core 622 self return, and the pressure is big more when rivers flow back, and first check valve 62 is sealed better, has played very big effect to the safety of guarantee pipeline.

Specifically, as shown in fig. 4, the valve body 621 of the first check valve 62 is composed of an upper cover 6211 and a lower cover 6212, and ultrasonic welding is preferably adopted between the upper cover 6211 and the lower cover 6212, so that the contact surfaces of the upper cover 6211 and the lower cover 6212 rub against each other to form fusion between molecular layers, and further, the first check valve 62 has the advantages of high strength, good sealing effect and the like. The lower part of the valve core 622 and the partial inner wall of the flow guide channel matched with the valve core 622 are in a conical structure and are in guiding fit, and a sealing ring 623 is arranged between the valve core 622 and the flow guide channel, so that the sealing performance is improved.

A further optimization of the first flow directing assembly 6 is also that, as shown in fig. 1 and 5, the first flow directing assembly 6 further comprises a tesla valve 63 disposed between the first jet 61 and the wastewater storage tank 5.

It should be noted that the setting position of the tesla valve 63 is not limited to the setting between the first check valve 62 and the wastewater storage tank 5, and it may be set between the first jet device 61 and the first check valve 62.
