Self-flushing anti-blocking waste water jar

Abstract

The invention discloses a self-flushing anti-blocking waste water jar. The self-flushing anti-blocking waste water jar comprises a shell and a shell cap arranged at the lower end of the shell, whereinthe upper end of the shell is provided with a water outlet end, and the lower end of the shell cap is provided with a water inlet end. The shell is internally provided with an inner pipe barrel, a lower plug, an upper plug, a first spring and a second spring, wherein a piston is arranged in the inner pipe barrel, and the piston is provided with a vertically-through first through hole; the lower plug is arranged at the lower end of the inner pipe barrel, a vertically-through second through hole is formed in the lower plug, and water flows out of the second through hole to push the piston to move upwards; the upper plug is arranged at the upper end of the inner pipe barrel and is provided with a vertically-through third through hole; the first spring is contained in the inner pipe barrel and is clamped between the upper plug and the piston; the second spring is pressed on the top end of the upper plug; the bottom of the upper plug is provided with a blocking needle, and the first through hole is used for allowing the blocking needle to be inserted in; and the upper plug is also provided with a thimble used for blocking the piston. A waste water discharging device of a pure mechanical structure is adopted, no circuit system is needed, and good self-control and anti-blocking characteristics are achieved.

Description

technical field [0001] The invention relates to a wastewater discharge device, in particular to a self-flushing and anti-clogging wastewater ratio. Background technique [0002] In the use of water purifiers, waste water devices are often used to discharge waste water during the water purification process to prevent clogging and secondary pollution. ) connected to a waste water discharge device. What use on the market at present is the discharge device such as the solenoid valve of electrical control, and this device is controlled by circuit, can control the opening and closing of switch. Generally, when the waste water is discharged, there will be a small hole in the closed state for daily waste water discharge, and when the machine is started, the solenoid valve will be activated to open the entire drainage channel and flush the RO membrane and pipeline for a short time. [0003] Yet the problem that above-mentioned setting can appear is: the use of 1 solenoid valve can ...

AI Technical Summary

Problems solved by technology

[0003] Yet the problem that above-mentioned setting can occur is: the use of 1 solenoid valve can cause excessive dependence to circuit, there is defect on the durability of service life and circuit control; 2 the use of solenoid valve can not avoid the problem of blocking, especially in In Northwest China, where the water hardness is relatively high, there are countless cases of damage to the reverse osmosis membrane due to the clogging of wastewater discharge, which affects the durability of the water purification device
