The working principle is as follows:
In the flushing stage, the water making machine starts to work, the RO membrane (reverse osmosis device) is flushed, the wastewater flows into the wastewater ratio from the wastewater pipeline of the RO membrane shell, flows into the first through hole 61 from the second through hole 71 of the wastewater ratio, and is discharged, the flow difference is formed because the inner diameter of the second through hole 71 is larger than that of the first through hole 61, the piston 6 continuously moves upwards under the pushing of the water flow, the piston 6 compresses the first spring 9, finally the first through hole 61 of the piston 6 is butted with the needle 11, the water flow is relatively large in the continuous process of the time, the flushing of the RO membrane is completed, and the continuous time can be controlled along with the flow difference.
In the water production stage, after the first through hole 61 of the piston 6 is in butt joint with the blocking needle 11, a tiny gap is reserved between the blocking needle 11 and the first through hole 61, so that the waste water can be continuously discharged, and the water production process is completed. When the water making machine stops working, the waste water discharge is stopped, and the piston 6 is restored to the original state under the action of the first spring 9.
In the anti-blocking stage, the water making machine continuously works, after the blocking needle 11 is butted with the first through hole 61, a tiny gap is reserved between the blocking needle 11 and the first through hole 61 to be blocked (if the blocking is formed under the condition of poor water quality), so that the internal pressure is continuously increased, the piston 6 is continuously compressed, the second spring 10 is also compressed, and finally the ejector pin 12 pushes the piston 6, so that the piston 6 is separated from the blocking needle 11 to form a flushing again until the blocking is released, and the second spring 10 is reset.
It should be understood, however, that the description herein of specific embodiments is not intended to limit the scope of the invention, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
