as shown in fig. 1, the utility model provides a safe food processor, including main part 1 that forms at least part processing chamber 11 and the bowl cover subassembly 2 of installing in processing chamber 11, for the security of ensureing food processor to use, bowl cover subassembly 2 includes a plurality of triggers 21, main part 1 includes at least two safety switch 12 that can be triggered in order to allow main part 1 circular telegram to switch on by triggers 21, food processor only installs at bowl cover subassembly 2 and is located main part 1, bowl cover subassembly 2 forms closed processing chamber 11 with main part 1, each safety switch 12 all triggers by triggers 21 simultaneously, the circular telegram return circuit just is switched on, food processor allows the operation.

The safety detection structure of the existing food processor is usually provided with a safety switch 12 on a single side, when the cup cover assembly 2 is installed on the single side above the processing cavity 11 or is tilted on the single side, the safety switch 12 on the upper edge of the cup cover assembly 2 and the processing cavity 11 is triggered by a trigger 21, and the cup cover assembly 2 on the opposite side of the contact side is not covered on the upper edge of the processing cavity 11, so that a power-on circuit of the main body 1 is conducted in the unsealed state of the processing cavity 11, and the processing cutter assembly 111 rotating at a high speed in the processing cavity 11 is exposed outside.

In order to solve the above problem, the utility model discloses in, as shown in fig. 3, each safety switch 12 sets up along the periphery of process chamber 11 relatively, when bowl cover subassembly 2 adopted the mode of unilateral installation again, and the safety switch 12 that triggers 21 on the bowl cover subassembly 2 can't make the opposite side simultaneously triggers, and then the circular telegram return circuit will be in the disconnected state always, and processing knife tackle spare 111 in the process chamber 11 can not rotate.

When the cup cover assembly 2 is installed on the main body 1 in a horizontal posture, the edge of the cup cover assembly 2 can be simultaneously attached to the upper edge of the processing cavity 11 in the circumferential direction, so that the safety switch 12 arranged on the opposite side of the periphery of the processing cavity 11 can be simultaneously triggered by the trigger piece 21, the processing cavity 11 is in an externally closed state, the safety switch 12 is triggered by the trigger piece 21 to enable an electrifying loop of the main body 1 to be conducted, the processing cutter assembly 111 can rotate to process food materials in the closed processing cavity 11 at a high speed, and the safety of the food processing machine is improved.
