Description

Anti-blocking waste water valve

Technical Field

The utility model relates to the field of water purifiers, and particularly belongs to an anti-blocking waste water valve.

Background

The water purifier has a very important part at the waste water end: a waste water valve. The main functions of the waste water valve are as follows: setting a certain numerical value of wastewater flow, and timely discharging the wastewater out of the filter element to prevent the filter element from scaling due to the enrichment of concentrated water in the filter element. Secondly, the pressure is kept in the filter element, so that the filter element can work normally.

The waste water valves commonly used in the market at present adopt a reducing mode to limit the flow, but small holes are easy to block, and a lot of waste water valves are blocked in the market. Because the TDS of the waste water is very high and can reach 1500+ mg/L at most, the small holes of the waste water valve are easy to scale, so that the waste water can not be discharged out of the filter element, and finally the filter element fails.

The prior application of the applicant provides an anti-blocking wastewater ratio structure which is not easy to block, and the patent numbers are as follows: CN201921907380.1 (publication No. CN211620013U), in the anti-clogging waste water ratio structure, an electromagnet is arranged outside a waste water ratio shell, when the electromagnet is electrified, the electromagnet generates suction force on a magnet at one end of a waste water ratio needle inserting needle, so that the needle inserting needle can be inserted into a waste water ratio needle sleeve, dirt, scale and the like in the needle sleeve are extruded out of the waste water ratio needle sleeve, and the cleaning process of the waste water ratio needle sleeve is realized; and when the electromagnet cuts off the power supply, the wastewater is reset under the action of the spring elasticity than the contact pin, so that the wastewater is cleaned than the needle sleeve by controlling the on-off of the electromagnet, the wastewater is effectively prevented from being blocked, and the whole structure is simple and compact and is easy to realize.

Although the structure realizes that the waste water is cleaner than the needle sleeve, thereby avoiding blockage, the electromagnetic structure is relatively complex, the use cost is higher, and the later-stage fault maintenance is inconvenient.
