Wherein, the fixed plate is except being used for installing the heating plate, thereby can also insulate against heat in order to reduce the downward transmission of the heat that the heating plate produced and improve thermal utilization ratio to the heating plate, and the fixed plate for example adopts thermal insulation material to make. Furthermore, the bottom plate and the fixing plate are provided with through holes for the rotating shaft or the motor shaft to penetrate through.

In this embodiment, the liquid heater is a three-section structure, and the cup cover, the cup body and the base are arranged from top to bottom. When the cup is used, the cup body is placed on the base, the motor is connected with the crushing knife in the cup body, food materials, water and the like are placed in the cup body, the cup cover is covered on the cup body, and after the power supply is switched on, the crushing knife works to make soybean milk, rice paste, crushed materials and the like. After the cooking is finished, the cup body can be taken down from the machine base so as to pour the cooking out of the cup body for eating.

Example four:

the difference between the present embodiment and the third embodiment is that the liquid heater omits to provide a base, and the motor is of a structure that is integrated with the motor.

As shown in fig. 2, the motor 32 is fixed to the heating plate assembly 20 and connected to the crushing blade 31, so that the motor 32, the heating plate assembly 20, and the crushing blade 31 can be synchronously detached from the cup body, and the overall machine type is small in size and compact in design. This embodiment may omit providing the cutter shaft, i.e., the motor shaft of the motor may be directly connected to the crushing cutter 31. When the cup body comprises the outer shell 13 and the inner cup 14, the motor 32 and the hotplate assembly 20 are housed together in the lower part of the outer shell 13, helping to promote miniaturization of the machine.

Where not mentioned in this application, can be accomplished using or referencing existing technology.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
