Referring to fig. 3, an exploded perspective view of a cup lid assembly of a food processor according to an embodiment of the invention is shown. The lid assembly includes a cup outer lid 402 and a cup inner lid 403, the cup inner lid 403 being embedded in the cup outer lid 402. The cup outer cover 402 is provided with a snap-fit portion that can snap into a corresponding snap-fit slot of the body assembly 1. The cup inner lid 403 is provided at a central portion thereof with a through hole to allow steam to be discharged when heating food in the cup assembly 4. Meanwhile, in order to prevent the food in the cup assembly 4 from overflowing when heated, an overflow preventing cap 401 may be further inserted into the through hole. The spill cap 401 may be a hollow cylinder with a top so as to be able to function as a measuring cup. Typically, a gasket 426 is sandwiched between the cup body assembly and the cap assembly for water resistance.

With further reference to fig. 4, there is shown an exploded perspective view of the cup body assembly and cup base of the food processor according to an embodiment of the present invention. The cup body assembly includes an inner cup 405, an outer cup 420, as well as a grip 407 and a handle 409. The inner cup 405 and the outer cup 420 may form a double-layered cup structure. As described above with reference to fig. 2, the double-layered cup structure encloses the NTC temperature sensor 413, the heating film 414, the thermistor 415, and the thermostat 418 and the fuse 419 between the inner cup 405 and the outer cup 420. Specifically, the heating film 414 is disposed on the lower bottom of the inner cup 405, and a temperature controller 418 and a fuse 419 are mounted on the heating film 414. An NTC temperature sensor 413 is provided outside the inner cup 405. In order to ensure the firm installation, the NTC temperature sensor 413 is firstly mounted on the NTC fixing glue 412 and then fixed on the outer side of the inner cup 405. The thermistor 415 is first mounted on the thermistor fixing glue 417, and then the thermistor fixing glue 417 is fixed to the upper bottom of the outer cup 420 by the press code 416. These electrical components of the heating device are electrically connected to the circuitry in the body assembly 1 via the upper connector 421. The inner cup 405 and the outer cup 420 are connected together by soldering to form a double-layered cup structure, and then the upper connector 421 is fixed to the lower bottom of the outer cup 420 to form an electrical connection with the electrical components of the heating apparatus. In addition, the upper connector 421 is provided with a plurality of contact pins for electrically connecting with the socket in the body assembly 1 through the corresponding through holes of the cup base 423. A stirring blade 404 may also be provided in the inner cup 405 of the body assembly, which is tightly locked to the body assembly via a blade lock 425. Typically, a drive motor and a transmission mechanism are provided in the body assembly, and rotation of the drive motor is transmitted to the stirring tool 404 through the transmission mechanism.

The cup body assembly shown in fig. 4 is provided with a handle 409 at the side of the outer cup 420. A channel is formed between the side of the outer cup 420 and the handle 409, and the upper link 411 may be disposed in the channel. The handle cover 410 is engaged with the handle 409 via the plug 408, and the handle cover 410 is provided with a notch so that the upper end of the upper link 411 can be exposed from the notch. When the cup cover assembly is fastened in place on the cup body assembly, the part of the upper connecting rod 411 exposed out of the notch of the handle cover 410 is pressed down, so that the upper connecting rod moves in the channel, the lower connecting rod 424 arranged in the cup base 423 is driven to trigger the switch, and the food processor can be powered on to operate. The lower link 424 is connected to the cup base 423 via an elastic member, so that after the cup body assembly is taken out from the food processor, the lower link 424 returns to the initial position, and drives the upper link 411 to return to the initial position. A lower link pressing block 422 is further provided in the cup base 423 to perform a buffering function when the lower link 424 returns to the original position via an elastic member.

When the food processor starts heating, the thermistor 415 of the outer cup 420 and the NTC temperature sensor 413 of the inner cup 405 feed back the temperature of the respective areas to the food processor at the same time, so that the temperature of the food cooked in the cup is accurately controlled. In addition, when the temperature of the heat generating film 414 is higher than a predetermined threshold, the thermostat 418 is automatically turned off, and when the temperature is reduced below the predetermined threshold, the thermostat 418 is automatically restored to the on state. The above-mentioned predetermined threshold value of the temperature, at which the NTC temperature sensor 413 and the thermistor 415 have failed but the heat generating film 414 is not damaged, at which the thermostat 418 can function to timely protect the heat generating film 414, may be set within a certain range below the upper limit of the operating temperature of the heat generating film 414. In addition, if the thermostat 418 fails, the fuse 419 will automatically melt when the temperature of the heating film 414 is too high. Therefore, double-layer protection can be formed on the heating film, and the safety performance in use is improved.

Because the vacuum layer is arranged between the outer cup 420 and the inner cup 405, the transmission of heat can be blocked, so that the outer cup 420 can not be heated to scald people when the food processor cooks food. When the cooking is stopped, the cup cover assembly and the sealing ring 426 enable food in the cup to be in a closed environment, and the food in the cup can delay heat dissipation due to the fact that the vacuum layer for blocking heat transfer exists between the outer cup 420 and the inner cup 405, and therefore the heat preservation effect is achieved. The outer cup 420 of the cup assembly may further be provided with a handle 407 to facilitate removal of the cup assembly after cooking is complete, the handle 407 being generally paired with the upper edge of the outer cup 420 and covered by a handle cover 406. Preferably, the pair of handles 407 are symmetrically oppositely disposed about the handle 409.

Referring to fig. 5, a perspective view of a food processor with a cup assembly removed is shown according to an embodiment of the present invention. As shown in fig. 5, the entire cup assembly can be removed from the food processor. Because the vacuum layer of the double-layer cup structure encapsulates the heating element of the heating device, the cup assembly can be put into a dish washing machine for cleaning, and the phenomenon that the cup body is in poor contact due to water leakage and the electric leakage hurts people is avoided.

The food processor may also include other necessary components to carry out its function, which are well known to those skilled in the art and will not be described in detail herein.

The food material sorting machine with the double-layer cup structure has the advantages of being accurate in temperature control, not prone to scalding people, good in heat preservation effect, capable of protecting heating components in a double-layer mode, convenient and fast to clean, safe to use and the like.

The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. It should be noted that several improvements, modifications and variations can be made to the present invention by those skilled in the art, but these improvements, modifications and variations do not depart from the spirit of the present invention and are deemed to fall within the scope of the present invention.
