The heating pipes are fixedly arranged at the lower side of the bottom of the cup body, and the stirring assemblies are fixedly arranged at the upper side of the bottom wall of the cup body. However, the above-mentioned products have the following problems. On the one hand, the cup body and the machine body cannot be detached, and the whole machine needs to be lifted when food is poured out or cleaned, which is not convenient for pouring out food or cleaning the cup body. On the other hand, since heating is performed under normal pressure, the temperature of the heated food does not exceed the boiling point of water, the heating time is long, the food is not easy to be pasty, and in the plateau area, the boiling point of water decreases accordingly, and the food is difficult to be cooked thoroughly. At present, there are also food processors in which the cup body and the machine body can be relatively detached. However, such food processors have the following problems. The cup body has an electric coupler of a heating pipe and a temperature control sensor, and if the cup body is directly washed, water will enter the electric coupler and the heating pipe, affecting the safety in use. The pressure heating food processor, such as the pressure soybean milk machine, has a cup body and a shell, a stirring assembly, a rotating assembly and a heating assembly that are a machine body, and can be heated, but the cup body cannot be detached from the machine body for cleaning.

[0003] Therefore, the food processors with heating function in the prior art have the following problems. The cup body cannot be detached from the machine body, which leads to inconvenience in pouring out food and cleaning the cup body. Or the cup body can be detached from the machine body, but when the cup body is detached, the electric coupler and the heating pipe are also detached. If the cup body is directly washed, water will enter the electric coupler and the heating pipe, affecting the safety in use. UTILITY MODEL CONTENTS

[0051] The heating assembly 700 is a heating disc, the top surface of the heating disc is attached to the bottom surface of the cup body 300, the food in the cup body 300 is heated conveniently, a first through hole 710 for allowing the first connecting piece 630 to pass through is formed in the middle of the heating disc, the diameter of the first through hole 710 is greater than the diameter of the first connecting piece 630, so that the first connecting piece 630 can move relative to the first through hole 710 easily, in this way, the heating disc and the stirring assembly 600 are relatively independent; a plurality of first contact feet 720 are arranged at the bottom of the heating disc, and a second through hole 240 for allowing the first contact feet 720 to pass through and connect is arranged at the bottom of the inner cover 200, so that the first contact feet 720 can extend out of the inner cover 200 to monitor the pressure of the pressure sensor.

[0052] Specifically, the embodiment further comprises an electronic pressure sensor 540, the electronic pressure sensor 540 is installed in the second cavity, and specifically, the electronic pressure sensor 540 is fixed to the motor cover 530, and the first contact feet 720 pass through the second through hole and are arranged in contact with the electronic pressure sensor 540. The heating disc is not fixed, and the heating disc can move downward together with the cup body 300 when the pressure in the cup body 300 increases, so that the first contact feet 720 act on the electronic pressure sensor 540 to obtain a pressure signal, and the pressure in the cup body 300 is monitored.

[0053] In addition, the embodiment further comprises elastic sheets 260, the inner cover 200 is uniformly provided with a plurality of mounting platforms 250, and the elastic sheets 260 are arranged on the mounting platforms 250; the heating disc is further provided with a second pin 730, the elastic sheet 260 is provided with a third through hole 261 and a fourth through hole 262 through which the first pin 720 passes, the second pin 730 comprises a contact portion 731 and a penetrating portion 732 which are arranged in connection, the diameter of the penetrating portion 732 is smaller than that of the contact portion 731, the penetrating portion 732 penetrates the third through hole 261, and the contact portion 731 abuts against the surface of the elastic sheet 260, as shown in Figure 6 .

[0054] The inner cover 200 is also provided with a fifth through hole 270 through which the second pin 730 passes, and the end of the second pin 730 passing through the inner cover 200 can be connected with a medium to ensure the stability of the up-down movement of the heating disc. When the pressure in the cup body 300 gradually increases, the cup body 300 and the heating disc move downward relative to the inner cover 200, and the elastic sheet 260 is deformed downward under pressure. When the pressure in the cup body 300 decreases to normal pressure, the elastic sheet 260 resets, and the cup body 300 and the heating disc also reset.
