  • Patent number: 5540362
    Abstract: A liquid soap supplying device of the present invention includes a tank for storing liquid soap, a discharging nozzle communicating with the tank through a pipe, a liquid soap supplying device for supplying liquid soap in the tank to the discharging nozzle, an air supplying device communicating with the discharging nozzle through a pipe and a mixing chamber for liquid soap and air arranged in the discharging port of the discharging nozzle. The liquid soap and air supplied under operation of each of the supplying devices are mixed and agitated in the mixing chamber so as to discharge the bubbled liquid soap. A pressuring device communicates with the air accumulation part at an inner upper part in the tank. An air feeding pipe is connected to the air accumulation part, and the liquid soap and air in the tank are fed to the discharging nozzle under an operation of the pressurizing device.
