Description

Technical Field

[0001] The invention relates to the field of household appliances, in particular to a juicer. Background Art

[0002] A juicer is a small machine that can quickly squeeze fruits and vegetables into juice. It was invented by Dr. Norman Walker in 1930. On this basis, designers later improved juicers of different styles and principles.

[0003] The motors used in traditional juicers are mostly coil stator motors, which are large in overall size and weight. After assembly, the overall structure of the juicer will be inconvenient and not light enough. In addition, the speed range and torque of the existing motor structure are limited, making it difficult to improve the working efficiency of the juicer. Summary of the invention

[0004] In response to the above problems, the present invention provides a juicer that adopts a circuit board motor and uses a PCB printed circuit board as the motor stator. The overall structure is compact, the volume is small, the weight is light, the speed range is large, and it has higher portability, which can further improve the working efficiency of the juicer.

[0005] The technical solution of the present invention is as follows:

[0006] A juicer comprises a feeding barrel, a juice extracting barrel and a base, wherein a blade is arranged in the juice extracting barrel; an installation cavity is arranged inside the base, a circuit board motor is arranged in the installation cavity, the circuit board motor comprises a circuit board, a rotor and a rotating shaft, a winding coil is arranged on the circuit board, and the circuit board is a PCB printed circuit board; a magnet is arranged on the rotor, the rotor and the circuit board are arranged opposite to each other, and the rotor is fixedly connected to the rotating shaft; the rotating shaft of the circuit board motor is drivingly connected to the blade.

[0007] In a further technical solution, the feeding cylinder, the juice extraction cylinder and the base are all detachably connected.

[0008] In a further technical solution, a sliding seal is provided at the connection between the rotating shaft of the circuit board motor and the juice extractor.

[0009] In a further technical solution, a cover plate for closing the installation cavity is provided at the bottom of the base.

[0010] In a further technical solution, the inner diameter of the juice extraction cylinder gradually decreases from top to bottom.

[0011] In a further technical solution, the circuit board is a multi-layer stacked structure, and the winding coils of the multi-layer circuit boards are connected by wires.

[0012] In a further technical solution, the circuit board and the rotor are provided in multiple groups, and the multiple groups of the circuit board and the rotor are nested on the rotating shaft in sequence, and an isolation plate is provided between two adjacent groups of the circuit board and the rotor.

[0013] Multiple sets of circuit boards and rotors work together to drive the shaft to rotate, which can achieve a wider range of speeds and greater torque to meet higher requirements.

[0014] The beneficial effects of the present invention are:

[0015] The juicer of the present invention adopts a circuit board motor, with a PCB printed circuit board as the motor stator. The overall structure is compact, the volume is small, the weight is light, the speed range is large, and the juicer has higher portability, which can further improve the working efficiency of the juicer.
