The pot body assembly 1 includes an outer shell, an outer pot 11, and an inner pot. The outer pot 11 is also referred to as the middle layer. The rice container 3 is disposed on the pot lid assembly 2, and the container cover 4 is detachably fitted with the rice container 3. The outer shell of the pot body assembly 1 and the pot lid assembly 2 are connected.

[0056] The rice container 3 is provided with several quantitative rice bins 31, and the bottom of each quantitative rice bin 31 is provided with a rice dispensing pipe 32; the upper end of the partition plate between two adjacent quantitative rice bins 31 is located below the upper opening end of the rice container 3, or in other words, there is a height difference between the upper opening end of the rice container 3 and the upper end of the partition plate; in actual application, the volume of two adjacent quantitative rice bins 31 is the same, or the volume of the quantitative rice bins gradually increases, which can be a multiple increase; the switch plate 5 is provided with a switch rice guide hole 51;

[0057] The switch plate 5 is slidably engaged with the lower end of the rice dispensing tube 32, and the driving device 6 drives the switch plate 5 to move in a straight line to switch the rice dispensing tube 32; the box cover 4 is detachably engaged with the upper opening of the rice box 3.

[0058] like Figure 2 , Figure 7 As shown, the rice container 3 has two rice measuring compartments 31: one large-capacity compartment and one small-capacity compartment. The large-capacity compartment has twice the capacity of the small-capacity compartment. In use, the small-capacity compartment is for small rice measurements, and the large-capacity compartment is for medium rice measurements. The large and small rice measuring compartments together constitute the large rice measurement mode. The selection mode can be set on the main control board for convenient use.

[0059] As a further improvement of the present invention: the pot lid assembly 2 includes a lid shell 21, a shell base plate 22, and a pot lid body 23.
