Abstract: A wireless temperature maintenance container has an accommodating space accommodating a transmitter circuit and a receiver circuit. The transmitter circuit comprises a first power processing circuit and a transmitter coil. The first power processing circuit receives a utility power and outputs a first direct current. The transmitter coil receives the first direct current and generates a magnetic field. The receiver circuit comprises a receiver coil, a second power processing circuit and a temperature controller. The magnetic field passes the receiver coil and an alternating current is generated. The second power processing circuit receives the alternating current and outputs a second direct current. The temperature controller receives the second direct current to control the temperature of the container. The transmitter circuit is on the first circuit board, and the receiver circuit is on the second circuit board. Distance between the first circuit board and the second board is 2 mm˜4 mm.

Abstract: A circulator apparatus comprises a housing, a processing module, and a display, a heater, and a motor are coupled to the processing module. The motor has a shaft connected to an impeller. The circulator apparatus further comprises a stand, and the stand has a base member, a supporting member, and a mounting member. Two ends of the supporting member are connected the base member and the mounting member respectively, the supporting member is configured to lift the housing, so the bottom side of the housing is located away from the base member by a predetermined distance.
