[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more centered elements can exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more centered elements can exist between them. The terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0026] As described in the background technology, existing steam heating machines generally use saturated steam to heat beverages into hot drinks. During the heating process, steam will be converted into water. The more steam is converted into water, the greater the impact on the concentration and taste of the beverage. At the same time, the more water content in the steam, the longer the heating time, which affects the efficiency of the beverage. At the same time, as the steam milk frother is used for a longer time, the scaling layer in the boiler will become thicker and thicker, causing the heating efficiency of the boiler to decrease. The water level line of the water level probe will rise after scaling, the boiler steam temperature will decrease, and the steam volume will decrease, which will further reduce the heating efficiency of the beverage and further increase the water content.

[0027] In addition, when the steam heating machine is heating a beverage, the operator needs to hold the beverage cup and insert the beverage cup into the steam heating rod at an angle, which may cause the risk of liquid spilling and scalding the operator.

[0028] The superheated steam device of the present invention can reheat the steam, converting the saturated steam into dry steam, and heat the beverage with the dry steam, thereby reducing the water content of the steam to reduce the dilution of the beverage, and increasing the temperature of the steam to improve the efficiency of beverage production. At the same time, the steam heating rod of the present invention has an automatic lifting function, which improves the convenience of operation when heating the beverage and reduces the risk of liquid spilling and scalding of the operator. The embodiments of the present invention are explained in detail below.

When it is necessary to heat a drink, first place the drink cup 5 to be heated on the water receiving box 60 and under the steam heating rod 33, and then select the corresponding temperature on the panel control screen assembly 10. The control panel controls the lifting member 42 to drive the steam heating rod 33 to descend, and the steam heating rod 33 descends along the avoidance groove 911 and the through-port, and the steam nozzle 34 extends into the beverage and sprays steam to heat the beverage, thereby reducing the water content of the steam to reduce the dilution of the beverage, and increasing the temperature of the steam to improve the beverage making efficiency. After the heating is completed, the control panel 202 controls the solenoid valve 7 to close and controls the driving member 41 to drive the lifting member 42 and the steam heating rod 33 to automatically rise, and the operator can take away the beverage cup 5.
