Background

Water purification devices are simply devices for producing purified water, which is widely used by us: drinking, chemical engineering, medical treatment, cultivation, planting, food, beverage, etc. The water purifier is mainly composed of an ultrafiltration membrane and an RO (reverse osmosis) membrane, can effectively filter rust, sand, colloid in water and chemical agents such as residual chlorine, odor, off-color, pesticide and the like adsorbed in the water, and can effectively remove bacteria, impurities, toxins, heavy metals and the like in the water.

The water purifier can be divided into a gradually-tightening type water purifier and a self-cleaning type water purifier according to the design grade of the pipeline. The traditional water purifier is a gradually-tightened water purifier, the filter element of the traditional water purifier is designed to be loose and tight in front and back in an internal pipeline, the traditional water purifier is composed of a PP melt-blown filter element, granular carbon, compressed carbon, an RO reverse osmosis membrane or an ultrafiltration membrane and rear active carbon in five grades, intercepted substances are deposited inside the filter element, and the traditional water purifier needs to be manually disassembled and washed at regular intervals to ensure the normal operation of a machine. The other type is a more advanced self-cleaning water purifier, two channels are designed in the water purifier, a washing water passage is added, washing water as common domestic water washes an in-machine filter element, particularly the raw water side of a membrane filter element when passing through the passage so as to achieve the self-cleaning effect, and the dirt intercepted by the water which originally flows off in two sections at the head and the tail in the moment of opening and closing a washing faucet is timely and quickly discharged.

Common domestic water purification unit is mostly gradually tight formula water purifier, and inside filter core needs the manual work to dismantle the change, and common water purification unit renews the filter core comparatively difficultly, needs to spend a large amount of time to need dismantle water purification unit in the operation, the operation is comparatively complicated, can cause certain damage to water purification unit's internal component, thereby causes water purification unit result of use to worsen.

Therefore, the invention designs the water purifying equipment with the filter element convenient to replace so as to solve the problems.
