How to keep the blade and motor of an electric citrus juicer safe

In the design and manufacturing process of electric citrus juicers, it is crucial to ensure the safety of blades and motors. This not only affects the user experience, but also directly relates to the user's life safety and property protection.

Blade safety design
Hidden and closed blade design
The blades of electric citrus juicers are designed to be hidden or closed to prevent users from coming into contact with sharp blades during installation, removal or cleaning of the equipment. This design effectively reduces the risk of accidental cuts and enhances the safety of the product.
Blade fixing and locking mechanism
The stability of the blade is crucial and it needs to be fixed to the spindle of the juicer through a sturdy locking mechanism to prevent it from loosening or flying out during high-speed rotation. This mechanism usually uses mechanical structures such as screws, buckles or spring locks to ensure that the blade remains stable during the juicing process.
Blade material and hardness
The blade is generally made of high-hardness, corrosion-resistant stainless steel to ensure that it is not easy to wear or deform during use. The blade edge is finely polished to reduce resistance and noise during cutting and improve the user experience.
Blade guard
Some electric citrus juicers are equipped with blade guards to further reduce the risk of users contacting the blades. The guards are usually made of transparent or translucent materials, allowing users to clearly observe the juicing process while ensuring safety.

Motor safety design
Motor overheating protection device
Motor overheating is one of the main causes of juicer failure and safety hazards. For this reason, electric citrus juicers are usually equipped with overheating protection devices. When the motor temperature exceeds the set threshold, the device automatically cuts off the power supply to prevent the motor from being damaged by overheating or even causing a fire.
Motor insulation and grounding protection
The insulation performance of the motor is the key to ensure its safe operation. The motor of the juicer usually adopts a double-layer insulation design to ensure good insulation performance even in a humid environment. For equipment that needs to be grounded, it is necessary to ensure that the resistance between the grounding terminal and the metal casing is lower than the standard specified value to prevent electrical leakage and electric shock accidents.
Motor load and speed control
The motor load and speed of the electric citrus juicer need to be precisely controlled to avoid failures caused by overload or overspeed. This process involves multiple aspects such as motor power matching, transmission system design, and control circuit optimization to ensure that the equipment is safe while operating efficiently.
Motor start and stop buffers
In order to avoid excessive impact and noise when the motor starts and stops, electric citrus juicers are usually equipped with start and stop buffers. These devices can smoothly control the speed and torque of the motor, reduce the wear and vibration of mechanical parts, and thus extend the service life of the equipment.
