After the water dropper is cleaned of dirt by the water dropper cover, the water dropper returns to normal work, the pressure applied to the pressure valve is reduced and closed, water in the cleaning box flows into the water dropper through the water outlet pipe, and the piston gradually descends after losing water pressure, so that the water dropper cover is driven to reset.
When the drip cover does not clear up the dirt completely, water level can continuously rise in the cleaning box to drive the piston and continuously rise, make the pressure of piston top can increase gradually, the relief valve can be opened when the pressure of piston top increases to the predetermined pressure that is greater than the relief valve, thereby the acidizing fluid of piston top can pass through in the cavity that the relief valve got into the carriage release lever, then in the drop head flows into from the apopore. The acid liquor enters the dripper to carry out acidolysis on dirt in the dripper, and the dirt is thoroughly cleaned. The dripper resumes normal work after the dirt clearance is accomplished, and the pressure that pressure valve received reduces and closes, and in the water in the clearance case flowed into the dripper through the apopore, the piston dropped gradually behind the water pressure that loses to drive the drip cover and reset, the pressure that the relief valve received reduces and closes simultaneously. Because be equipped with first check valve in the cavity, and first check valve is opened by inlet opening to apopore direction, so the water in the dripper can't get into in the cleaning box from the cavity.
