An automatic liquid soap supplying system, comprising:
- a plurality of soap dispensing main bodies, each of said soap dispensing main bodies being mounted on a countertop, while each of said soap dispensing main bodies being provided with a soap discharging outlet for discharging a liquid soap and a sensing area for emitting a soap dispensing signal when sensing a human body part;
- a plurality of soap dispensing components, mounted under said countertop and connected to each of said soap dispensing main bodies, respectively, each of said soap dispensing components being provided with a liquid soap tank used for storing said liquid soap, a soap dispensing machine mounted on said liquid soap tank so as to convey said liquid soap to said soap discharging outlet via a soap discharging pipe, and a control box connected to said sensing area while used for receiving said soap dispensing signal so as to control said soap dispensing machine to provide said liquid soap to said soap discharging outlet from said liquid soap tank;
- a liquid soap filling tank, mounted under said countertop for storing said liquid soap, and connected to each of said liquid soap tanks through a soap supplying pipe provided at one end thereof with an exhaust valve for discharging air, said liquid soap filling tank being provided thereon with a liquid soap filling port used for said liquid soap to be filled, and a liquid level detection unit used for detecting a liquid level condition of said liquid soap and emitting a signal for supplying said liquid soap, in which the height of said liquid level detection unit is higher than that of each of said liquid soap tanks, such that a differential hydrostatic pressure is formed by said liquid soap inside said liquid soap filling tank and that inside each of said liquid soap tanks, whereby said liquid soap is filled into each of said liquid soap tanks automatically from said liquid soap filling tank through the differential hydrostatic pressure;
- a mounting component, including a fixing part mounted on said countertop, a liquid soap filling pipe provided on said fixing part and connected to said liquid soap filling port so as to allow said liquid soap to be filled to said liquid soap filling tank from said countertop, as well as a light emitting component provided inside said countertop and allowed for emitting a ray so as to provide said fixing part thereon with a photo display area for supplying liquid soap;
- and
- a control unit, electrically connected to said liquid level detection unit and said light emitting component, respectively, for receiving said signal for supplying liquid soap emitted on the basis of the liquid level condition, while driving said light emitting component to emit the ray depending on said signal for supplying liquid soap, so as to form said photo display area for supplying liquid soap on said fixing part.
