The bottom of the heating cup 100 is provided with an infrared light-transmitting structure 110 opposite to the infrared temperature measuring unit 400. By setting the infrared temperature measuring unit 400, the temperature inside the heating cup 100 can be directly measured without direct contact, so as to avoid the influence of the rotation of the heating cup 100 and other factors on the measurement.
