Descaling device, system, and descaling method of electronic toilet and liquid supply device, system, and cleaning method of electronic toilet

A cleaning method by using a liquid supply device for an electronic toilet,

• the liquid supply device, comprising:
• a detergent storage box, comprising:
• a detergent space configured to house a detergent;
• and
• a piston space configured to house a piston assembly and in communication with the detergent space;
• the piston assembly comprising a piston rod configured for a reciprocating movement in the piston space;
• and
• a driving mechanism configured to drive the piston rod to reciprocally move in the piston space,
• the cleaning method comprising:
• in response to a cleaning request, controlling the driving mechanism of the liquid supply device to drive the piston rod to open a water inlet end check valve and close the output end check valve;
• after a preset water inflow period has passed, controlling the driving mechanism to drive the piston rod to close the water inlet end check valve and close the output end check valve;
• after a preset dissolving period has passed, controlling the driving mechanism to drive the piston rod to close the water inlet end check valve to close and open the output end check valve.

A toilet comprising:

• a liquid supply device, the liquid supply device comprising:
• a detergent storage box, comprising:
• a detergent space configured to house a detergent;
• and
• a piston space configured to house a piston assembly and in communication with the detergent space;
• the piston assembly comprising a piston rod configured for a reciprocating movement in the piston space;
• a driving mechanism configured to drive the piston rod to reciprocally move in the piston space,
• wherein a water inlet end check valve is disposed at a water inlet end of the piston space and the reciprocating movement of the piston rod in the piston space controls an opening or a closing of the water inlet end check valve, and
• wherein an output end check valve is disposed at a detergent saturated solution output end of the piston space and the reciprocating movement of the piston rod in the piston space controls an opening or a closing of the output end check valve, and
• a liquid suction chamber disposed between the piston rod and the output end check valve;
• and
• a liquid suction chamber valve device disposed at the liquid suction chamber, wherein the reciprocating movement of the piston rod in the piston space controls an opening or a closing of the liquid suction chamber valve device.
