Abstract:
A temperature-controller equipped foot-bathing device, comprising:a basin being substantially a hollow vessel for loading and circulating a liquid, in which a space is available for accommodating a pair of user's feet; a heating device being controlled by a microprocessor for heating intermittently according to a timing clock and composed of an electrically nonconductive quartz tube entangled with a heating element, wherein the heating element is fixed uniformly with Magnesium oxide powder before being shielded with Mica cloth on the outmost layer of the quartz tube; the heating element is thus separated from the liquid flowing in the quartz tube, and the heat generated from the heating element is well insulated for protecting components and avoiding malfunctions; a water pump further comprising a motor of bipolar magnetic core and a fan leaf mounted on a shaft thereof, wherein the fan leaf is driven to extract the liquid upwardly to thereby enable the liquid to cycle repeatedly when the motor operates; an air-feeding device including a tapered air duct, which penetrates the basin connect with an intake duct extended from a gas intake, wherein a spiral swivel for regulating airflow is provided to the air duct and locked at the basin; a reverse conical body is disposed underneath the spiral swivel; and the conical body will descend to choke the air duct to close the air channel when the spiral swivel is turned downwards and vice versa; and an electronic control device, which enables a user to directly and externally control the liquid temperature, and by taking advantage of difference in temperature resistible of two temperature-control switches, a double-security mechanism is erected; wherein the liquid flows through a guiding hole into the heating device for being heated, then the motor would drive the fan leaf to have the heated liquid passed through a Y-connector and pumped to go upwardly for blending with input air through the gas intake, and the bubble-contained liquid then spouts from three water outlets in the basin.
