[0003] However, a certain proportion of waste water will be generated during the operation of reverse osmosis water purifiers. The traditional waste water discharge method of reverse osmosis water purifiers is simple and extensive, lacking precise detection and adjustment of waste water flow; due to the inability to accurately control the waste water discharge volume, it not only causes a large amount of water resource waste, reduces the output of pure water, but also makes the reverse osmosis membrane bear excessive pressure due to unreasonable waste water discharge, shortening its service life, and thus increasing the maintenance cost of the water purifier; in addition, the traditional waste water discharge control device has poor adaptability when dealing with changes in different water qualities and water use requirements, and cannot flexibly adjust the waste water discharge ratio according to the actual situation.

[0020] In order to make the content of the present invention easier to be clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The same reference numerals are used for the same components. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0021] As Figure 1As shown in the figure, in this embodiment, a waste water discharge control device for an efficient water purifier is provided, including: a waste water inlet pipe 1, a regulating solenoid valve 3 arranged on one side of the waste water inlet pipe 1, a waste water ratio regulator 4 arranged on one side of the regulating solenoid valve 3, a control component 7 arranged on the top of the waste water ratio regulator 4, a waste water discharge pipe 6 arranged on one side of the control component 7, and an electronic control device; a flow sensor is arranged on the waste water inlet pipe 1. The working principle of the flow sensor is that when the waste water in the waste water inlet pipe flows through this sensor, it drives the worm wheel to rotate. The rotation speed of the turbine is proportional to the flow rate of the waste water. By measuring the rotation speed of the turbine, the flow rate of the waste water can be measured. Moreover, the flow sensor has a control unit inside, and the control unit is used to calculate the data detected by it and transmit the calculation result; the model of the flow sensor is LWGY liquid turbine flow sensor, which is prior art and will not be elaborated here too much. The flow sensor is used to monitor the flow rate inside the waste water inlet pipe 1 in real time; the waste water inlet pipe 1 is connected to the regulating solenoid valve 3 through a first connecting water pipe 2, and the first connecting water pipe 2 is a tee water pipe; the regulating solenoid valve 3 is in multiple groups, and they are the first solenoid valve, the second solenoid valve, the third solenoid valve, and the fourth solenoid valve in sequence along the setting direction of the first connecting water pipe 2. The second solenoid valve, the third solenoid valve, and the fourth solenoid valve are connected to the water inlet connecting pipe 401 on one side. The regulating solenoid valve 3 is used to control the waste water flow rate, and this control is the first control; the control component 7 penetrates through the top of the waste water ratio regulator 4 and is used to control the flow rate of the waste water ratio regulator 4. The waste water ratio regulator 4 and the control component 7 can reduce the waste water discharge amount and improve the water resource utilization rate under the condition of ensuring the normal operation of the water purifier and the water purification quality; the electronic control device is arranged inside the water purifier, its model is U2B MOD_ML307X_LGA109P, and it is electrically connected to the flow sensor, the regulating solenoid valve 3, the air pump 712, and the exhaust solenoid valve 703.

[0022] As Figure 2As shown, the wastewater proportion regulator 4 includes: a regulator body 405, and an inlet connecting pipe 401 and an outlet connecting pipe 402 provided at both ends of the regulator body 405; a flow chamber is provided inside the regulator body 405; one end of the inlet connecting pipe 401 is connected to the regulating solenoid valve 3; one end of the outlet connecting pipe 402 is connected to the wastewater discharge pipe 6 through a second connecting water pipe 5, and the inner diameter of the outlet connecting pipe 402 is smaller than that of the inlet connecting pipe 401; the connection between the inlet connecting pipe 401 and the regulator body 405 is the water inlet end 403; the connection between the outlet connecting pipe 402 and the regulator body 405 is the water outlet end 404; the flow chamber is in communication with the water inlet end 403 and the water outlet end 404, and a control component 7 is provided inside it. A sealing connector 406 is provided at the connection between the regulator body 405 and the control component 7. The sealing connector 406 is used to ensure the internal sealing of the regulator body 405 and prevent wastewater leakage.

[0023] As Figure 2-3As shown, the control component 7 includes: a cylinder 705, an intake pipe 702 and an exhaust pipe 704 arranged on both sides of the cylinder 705, and a piston 706 slidably connected to the cylinder 705; a piston 706 is provided inside the cylinder 705, one end of the piston 706 is provided with a connecting rod 707, one end of the connecting rod 707 is connected to the top block 710, a sealing ring 711 is provided at the bottom of the top block 710, and the top block 710 is adapted to the inner diameter of the flow chamber. During operation, the position between the top block 710 and the flow path formed by the flow chamber and the water inlet end 403 and the water outlet end 404 is controlled to achieve the control of the waste water flow rate; a fixed seat 708 is provided on the top wall of the cylinder 705, the fixed seat 708 is fixedly connected to the top wall of the cylinder 705, and a spring 709 is provided at the bottom, and the telescopic end of the spring 709 is connected to the piston 706; during operation, the piston 706 drives the connecting rod 707 and the top block 710 to reciprocate in the flow chamber, thereby achieving precise control of the waste water flow rate inside the regulator body 405. This control is a secondary control; through the dual control of the waste water flow rate, the redundancy of the present invention is increased. When one control device fails, the other control device can still continue to function; thus, the waste water discharge can be adjusted more precisely, ensuring that the waste water discharge ratio is more accurate, thereby improving the working efficiency and water purification quality of the water purifier; both sides of the cylinder 705 are respectively communicated with the intake pipe 702 and the exhaust pipe 704; specifically, one end of the intake pipe 702 is connected to the output end of an air pump 712 through a check valve 701, and the air pump 712 is electrically connected to the flow sensor; the check valve 701 can ensure that the gas can only flow from the air pump 712 to the intake pipe and will not flow back from the intake pipe 702 to the air pump 712 for any reason, reducing the failure of the waste water flow rate control caused by gas backflow, thereby improving the stable operation and working efficiency of the control component 7; one end of the exhaust pipe 704 is provided with an exhaust solenoid valve 703, and a filter 8 is provided at the connection between it and the cylinder 705; during operation, when the flow sensor detects that the flow rate of the waste water entering the pipe 1 is large, this information is transmitted to the control unit of the flow sensor. The control unit quickly calculates the correct waste water flow rate according to the preset waste water ratio and the actual water inlet flow rate under different conditions, forms a corresponding instruction, and transmits the instruction to the air pump 712. The air pump 712 supplies gas into the cylinder 705 through the intake pipe 702 according to the corresponding instruction. At this time, the exhaust solenoid valve 703 is in the closed state, and the gas moves the piston 706 towards the regulator body 405. At this time, the spring 709 undergoes elastic deformation, and the piston 706 drives the top block 710 to move in the flow chamber through the connecting rod 707, partially blocking the flow path formed by the flow chamber and the water inlet end 403 and the water outlet end 404, thereby controlling the waste water flow rate;When the flow sensor detects that the flow rate of the wastewater entering the pipe 1 is small, the control unit quickly calculates the correct wastewater flow rate according to the preset wastewater ratios corresponding to different situations and the actual influent flow rate, forms corresponding instructions, and transmits the instructions to the air pump 712 and the exhaust solenoid valve 703. The air pump 712 stops working. At this time, the exhaust solenoid valve 703 is activated, and the gas is discharged from the cylinder 705 through the exhaust pipe 704. At this time, the spring 709 drives the piston 706 to reset, and the piston 706 drives the top block 710 to move in the reverse direction in the flow chamber through the connecting rod 707, expanding the flow path formed by the flow chamber and the water inlet end 403 and the water outlet end 404, thereby increasing the wastewater flow rate.

[0024] As Figure 2-3 shown, the filter 8 includes: a filter mesh 801 and an activated carbon layer 802; the filter mesh 801 and the activated carbon layer 802 are distributed along the transverse direction of the exhaust pipe 704; the filter mesh 801 can preliminarily filter large particle impurities mixed in the discharged gas, and the gas after preliminary filtration passes through the activated carbon layer 802 in sequence. The activated carbon layer 802 can adsorb smaller molecules and odors, and filter the odors and harmful gases therein, reducing environmental pollution and damage to the exhaust solenoid valve 703, thereby ensuring the smooth and efficient operation of the entire process of the present invention.

[0025] The above are only the preferred embodiments of the present invention patent, and are not intended to limit the present invention patent. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention patent shall be included in the protection scope of the present invention patent.
