Juice Extracting and Stirring Cup with Magnetic Drive

The problem

Consumers often need to prepare different types of beverages throughout the day: fresh fruit juices, instant coffee, milk tea, or protein shakes. Traditionally, this requires multiple pieces of equipment—a juicer, a blender, a spoon, and separate cups. This creates storage issues and increases cleanup time. Furthermore, many electric mixing cups use blades submerged in the liquid, which can be dangerous to clean and prone to trapping food residue in hard-to-reach crevices. Manual stirring is inefficient for thick mixes like matcha or cocoa powder, while manual juicing is messy if the juice doesn’t flow directly into the drinking vessel.

The solution

This patent describes a unified cup system that handles both extraction and mixing without complex internal mechanisms.

1. Cup Body: The main container features an accommodating space with a top opening. Inside the side walls, a locking structure is formed to secure the juicing components.
2. Juicing Disc: A removable tray sits inside the cup. It has a central cone shape and multiple holes across its surface. Users place half-cut fruits on the cone; pressing down extracts juice which flows through the holes directly into the cup’s interior.
3. Stirring Member: A simple rod containing a magnet bar rests at the bottom of the cup’s interior. Because it lacks blades or complex shapes, it is easy to remove and wash.
4. Rotating Device (Base): Attached to the bottom exterior of the cup is a housing containing a motor, power supply, and switch. A connecting rod with magnetic blocks rotates within the base.
5. Magnetic Coupling: The rotating magnetic blocks in the base attract the magnet bar in the stirring rod. As the base motor turns, the magnetic force spins the rod inside the cup indirectly. This eliminates the need for shafts passing through the cup floor, reducing leak risks and simplifying hygiene.

Who it is for

• Travel Mug Brands: Looking for differentiated products that offer more than just thermal retention, appealing to commuters who make their own drinks.
• Outdoor Gear Manufacturers: Targeting campers and hikers who need lightweight, multi-purpose kitchen items that don’t require bulky blenders.
• Office Supply Retailers: Selling to professionals who want quick access to fresh juice or perfectly mixed instant coffee without leaving their desks.
• Private Label Buyers: Seeking a compact appliance concept that combines two popular categories (juicers and mixers) into one SKU to reduce shipping volume and retail shelf space.

How it works

The main parts

Operating Steps

1. Juicing Mode: Insert the juicing disc (2) into the cup. Cut a fruit (e.g., orange or lemon) in half. Press the fruit onto the central cone (22). Juice flows through the holes (23) into the cup body below the disc. Remove the disc to drink or add water/tea.
2. Mixing Mode: Add ingredients (coffee powder, milk, sugar) to the cup. Ensure the stirring member (4) is at the bottom. Place the cup on the rotating device base (5) or attach them if integrated. Turn on the power switch (54).
3. Magnetic Action: The motor (52) rotates the connecting rod (55) in the base. The magnetic blocks (551) pull the magnet bar (41) in the stirring rod, causing it to spin rapidly. This mixes the contents evenly without manual agitation.

Applications

Commuter Breakfasts

Ideal for office workers preparing fresh orange juice or mixing instant oatmeal/coffee before work. The compact size fits standard cup holders, and the magnetic stirrer ensures powders dissolve fully without clumps.

Camping and Hiking

Backpackers can use this to extract vitamin C from local fruits or mix powdered energy drinks. The lack of sharp submerged blades makes it safer to handle in outdoor conditions, and the easy-clean rod reduces maintenance effort when water supplies are limited.

Infant Food Preparation

Parents can quickly blend soft fruits into purees by juicing first and then stirring with warm water or formula. The smooth magnetic rod is easier to sanitize than blade-based blenders, ensuring hygiene for baby food.

Gym and Fitness Shakes

Athletes mixing protein powder or creatine benefit from the powerful magnetic stirring action, which breaks up powder clusters effectively. The ability to juice fruits directly adds natural flavor without needing a separate shaker bottle.

Where it is less suitable

• Hard Vegetables: The manual cone disc is designed for soft citrus fruits; carrots or apples may require pre-cutting or a stronger mechanical juicer.
• Large Batches: This is a personal-sized cup, not suitable for family-sized meal prep or commercial juice bars.
• Thick Smoothies: While it stirs well, it does not have high-speed blades to crush ice or fibrous greens like kale into a completely smooth consistency.
