A safe and reliable compound coupler and food processing machine

Abstract

The invention relates to a safe and reliable composite coupler and food processing machine. The safe and reliable composite coupler comprises an upper coupler and a lower coupler which are connected and matched with each other. The upper coupler comprises a fixed shell and an upper electrode. The lower coupler comprises a lower electrode. The upper electrode and the lower electrode are electrically connected when the upper and lower couplers are connected. The lower coupler further includes a housing having an opening on one side. The lower electrode is mounted in the housing. The housing is provided with a first through hole for the upper electrode to pass through. The lower coupler further comprises a microswitch embedded in the housing. The upper coupler triggers the microswitch when the upper and lower couplers are connected. By embedding the microswitch in the coupler, the food processing machine can be installed and positioned just by the aligning the upper and lower couplers, soas to be simple in structure and easy to operate. The microswitch is embedded in the coupler, and only needs to be connected to the circuit of the coupler. The food processing machine has simple internal circuits and is convenient to produce.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a safe and reliable coupler assembly for a food processing machine and a food processing machine. Background technique [0002] Food processing machines are widely used in people's lives. The existing commonly used food processing machines include a base with a built-in motor and a stirring cup arranged above the base. The stirring cup includes a cup body and a cup arranged at the upper opening of the cup body. The cover and the mixing cup are provided with a pulverizing knife, and the motor drives the pulverizing knife to rotate through a coupling to pulverize the ingredients in the mixing cup. The stirring cup is also provided with a knife plate and a heating body, the heating body is usually a heating tube and is arranged around the periphery of the knife plate; the stirring cup is also usually equipped with a temperature controller and an anti-overflow electrode. The temperatu...

Problems solved by technology

In the existing scheme, the micro switch and the coupler are separately arranged, so that between the stirring cup and the machine base, the structure that needs to be positioned when the stirring cup is installed includes at least the coupler, the shaft coupling and the micro switch structure, and the positioning There are many structures and precise positioning is required, and the user experience is poor

At the same time, due to the need to set multiple positioning structures, the upper surface of the machine base is complicated to set, and there are many dead angles, which also makes the machine base difficult to clean, and also makes the machine base need to install multiple accessories during the production process, resulting in low production efficiency.

In addition, the coupler and the micro switch are set separately and need to be connected by wires respectively, which makes the internal circuit complicated and the production and maintenance efficiency low

The coupler and the micro switch are two accessories, which need to be managed separately in the production management process, resulting in poor production efficiency and high cost

The two accessories also add bulk, making the food processor bulkier
