Portable Water Cup with Built-In Motorized Stirring Mechanism

The problem

When mixing powdered drinks, protein supplements, or flavor additives into water on the go, manual shaking often leaves dry clumps stuck to the bottom or sides of the bottle. Carrying a separate spoon or whisk is inconvenient, and standard battery-operated stirrers usually require multiple loose parts that are easy to lose during travel. Users need a single unit where the mixing tool is integrated, powered reliably, and easy to clean without disassembling complex electronics.

The solution

This design integrates the entire stirring mechanism into the lid assembly of a portable water cup.

1. The cup lid (4) screws onto the cup body (3) using spiral threads (41).
2. A cavity (6) sits at the top of the cup lid. Its bottom surface holds a fixed support column (61).
3. A rotating locking shaft (5) is mounted inside the support column, extending forward and backward.
4. A rechargeable portion (53) inside the locking shaft powers a locking motor (55) at the rear of an inner locking rotating shaft (551).
5. At the front end of the locking shaft, a first locking part (8) slides into place. It consists of a plate (86), a first casting lug (82), a first bolt (83), and a second bolt (85).
6. A stirring head (7) connects to the first locking part via a second locking part (71) featuring a clamping hole (72) and a connection slot (73).
7. A stirring motor (62) fixed behind the support column drives the shaft through a first runner (52), a second runner (621), and a conveyer belt (622).
8. Touch controllers (541) inside locking holes (54) in the slide chamber (51) activate the motor.

Who it is for

• Drinkware brands looking to add a self-mixing model to their catalog for fitness or outdoor consumers who want hands-free blending.
• Amazon private-label sellers sourcing electronic water bottles that differentiate themselves from standard shaker bottles with mechanical parts.
• Promotional product wholesalers supplying branded tech-drinkware to corporate clients, gyms, or sports teams.
• Outdoor and camping gear distributors offering portable hydration solutions where carrying extra utensils is impractical.

How it works

The main parts

Operating steps

1. Fill the cup - pour water and powder into the cup body (3).
2. Close the lid - screw the cup lid (4) onto the cup body using the spiral threads (41).
3. Activate the motor - touch the touch controllers (541) inside the locking holes (54) of the slide chamber (51).
4. Stirring begins - the stirring motor (62) turns the second runner (621), pulling the conveyer belt (622) to spin the first runner (52) and the rotating locking shaft (5).
5. Mix the drink - the stirring head (7) spins inside the cup body, dissolving the contents.
6. Remove the head - slide the first locking part (8) out to detach the stirring head (7) via the clamping hole (72) and connection slot (73) for cleaning.

Applications

Gym and fitness centers

Athletes mixing protein powder or pre-workout supplements between sets often lack access to spoons or blenders. The motorized stirring head dissolves thick powders evenly inside the sealed cup, saving time and preventing clumps during short rest periods.

Office desks and workspaces

Workers mixing instant coffee, tea, or nutritional shakes at their desks can use the touch controller to stir their drinks. The integrated lid means there are no loose stirring rods to wash in the office sink or misplace in drawers.

Camping and hiking trips

Outdoor enthusiasts need lightweight gear without sacrificing functionality. By combining the water bottle and the mixer into one rechargeable unit, hikers avoid packing separate whisks or relying on vigorous shaking that can spill liquids if the lid is not fully secured.

Commuting and travel

Passengers on trains or in cars cannot easily shake a bottle without spilling or disturbing others. The touch-activated stirring mechanism allows users to mix meal-replacement shakes smoothly while seated, keeping the motion contained entirely inside the cup body.

Where it is less suitable

• Hot beverages above the rated temperature - the patent does not specify thermal limits for the electronic components in the lid cavity, so boiling liquids may damage the rechargeable portion or motors.
• Dishwasher cleaning of the lid - the cavity contains motors, touch controllers, and a rechargeable portion, meaning the lid assembly likely requires hand washing or careful wiping rather than full submersion.
• Heavy industrial mixing - this is designed for soluble drink powders and liquids, not for thick batters, viscous pastes, or heavy food processing tasks.
