　　Four-way movement algorithm (maintains floating posture when moving forward/backward to avoid rapid power consumption)

　　Sound and light interaction (emits light and plays children's songs with movements when floating; automatically reduces sound and light intensity to extend battery life when the battery is low)

　　Waterproof Scenarios: Floating play in swimming pools, water play in bathtubs; simply wipe the body dry before charging, no need to worry about residual water affecting charging

　　2. Tongqudu Rechargeable Floating AI Story Projection Ball

　　Core Specifications: 10cm-diameter spherical design, lightweight EVA shell (density < 1g/cm³, fully floating), IP67 waterproof, built-in 1500mAh lithium battery (supports USB-C magnetic charging), approximately 5-hour battery life

　　Rechargeable Highlights: Magnetic charging port hidden at the bottom of the ball (simply attach to the base for charging, no need to open the cover); 1.5-hour charging for a full charge; supports "charging protection" function, automatically cuts off power after full charge to avoid battery damage from overcharging

　　Floating & Durability Highlights: Anti-slip texture on the ball surface for easy grasping by children; built-in balance weight ensures the projection lens faces upward when floating, without affecting content display; EVA material is drop-resistant and impact-resistant (no cracks in 2-meter drop tests), stain-resistant and easy to clean, no fading after long-term water contact

　　AI Interaction Highlights:

　　Voice-activated story on-demand (supports commands like "play ocean stories" "sing children's songs"; automatically shortens content duration when the battery is low)

　　Projection interaction (projects cartoon patterns when floating, switches content via AI-sensing hand movements)

　　Power-saving mode (automatically turns off projection and retains only basic voice functions after 10 minutes of inactivity)

　　Waterproof Scenarios: Floating use in outdoor swimming pools, bathing use in bathrooms; wipe the body with a dry cloth before charging

　　II. Adult-Oriented: Rechargeable & Portable Smart Interactive Toys

　　Fuyang Rechargeable Floating AI Bluetooth Speaker Toy

　　Core Specifications: 12cm-diameter disc shape, waterproof ABS + built-in buoyancy cotton (half the volume exposed above water when floating), IP67 waterproof, built-in 2000mAh lithium battery (supports USB-C sealed charging), approximately 6-hour battery life (at 50% volume)

　　Rechargeable Highlights: Charging port equipped with a waterproof rubber plug (unplug the plug for charging, reaches IP67 waterproof after closing); 2-hour charging for a full charge; remaining battery level can be checked via mobile APP; supports AI "scheduled shutdown" function (avoids power consumption from forgetting to turn off)

　　Floating & Durability Highlights: Arc-shaped edge anti-tipping design for stable floating in wind and waves; scratch-resistant shell, non-aging even after long-term sun and rain exposure; Bluetooth module treated for moisture resistance

　　AI Interaction Highlights:

　　Voice control (supports commands like "play music" "check weather" "set shutdown in 1 hour")

　　Scene linkage (after connecting to the APP, synchronizes light flashes with music rhythm; lights turn red to remind when the battery is low)

　　Anti-loss reminder (automatically emits sound when 10 meters away from the mobile phone; increases reminder frequency when battery is below 10%)

　　Waterproof Scenarios: Floating use in pool parties, water play at the beach; ensure the rubber plug is fully closed before charging

　　User Feedback: "Magnetic charging is very convenient, a full charge works for an afternoon without issues. It’s safe to play music while bathing without worrying about water ingress, and the battery life is sufficient for daily use"

　　III. Pet Category: Rechargeable & Chew-Resistant AI Interactive Devices

　　Chongleduo Rechargeable Floating AI Interactive Ball

　　Core Specifications: 8cm spherical design, military-grade chew-resistant TPU material (density 0.95g/cm³, natural floating), IPX8 waterproof, built-in 800mAh lithium battery (supports wireless inductive charging), approximately 8-hour battery life (medium interaction frequency)

　　Rechargeable Highlights: Adopts wireless inductive charging (no need to touch the port, simply place on the charging base); 1-hour charging for a full charge; battery compartment wrapped in a waterproof film, ensuring battery safety even if chewed by pets

　　Floating & Durability Highlights: Built-in flexible buoyancy skeleton (restores floating shape after extrusion deformation); concave-convex texture on the surface increases pets’ grip; TPU material can withstand 20kg bite force, no sharp parts

　　AI Interaction Highlights:

　　Sensing interaction (automatically floats and moves when touched by pets, automatically enters sleep mode to save power after 5 minutes of inactivity)

　　Voice commands (supports commands like "attract the dog" "play cat-attracting sounds"; automatically reduces sound volume when the battery is low)

　　Mobile APP control (customize floating paths, check remaining battery level, set "automatic sleep period")

　　Waterproof Scenarios: Floating use in pet swimming pools, water play outdoors on rainy days; no need to dry before charging, just place directly on the base

　　Special Features: Automatically lights up when floating at night; lights flash to remind charging when the battery is low

　　IV. Technical Analysis: Core Design of Rechargeable Waterproof AI Toys

　　Key Rechargeable Design Points:

　　Charging Methods: Prioritize magnetic charging and wireless inductive charging (to avoid water ingress risk of plug-in ports); plug-in ports must be equipped with waterproof rubber plugs/sealing caps (reaching the same waterproof level as the body when closed)

　　Battery Protection: Adopt polymer lithium batteries (small size, high safety), wrapped in waterproof films + anti-drop buffer layers to avoid damage from water ingress/impact; equipped with overcharge, over-discharge, and short-circuit protection chips

　　Battery Life Optimization: AI intelligent power-saving mode (automatic sleep when inactive, reduced sound/light power consumption when battery is low); automatically adjust power according to usage scenarios (e.g., higher power consumption in pool mode than in bathroom mode)

　　Coordination of Waterproofing and Charging:

　　Charging Port Sealing: Magnetic ports use waterproof sealing rings; wireless charging coils are isolated from the body with waterproof glue to ensure complete waterproofing of charging components and circuit compartments

　　Charging Safety: The device must be removed from water during charging (some high-end models support "underwater charging", but clear usage conditions must be marked) to avoid short circuits during charging

　　Durability Enhancement:

　　Hidden Design of Charging Components (e.g., no exposed structure on the contact surface of the wireless charging base) to avoid damage from pet chewing or children’s accidental contact; battery compartment and body are integrally formed to reduce water ingress gaps

　　V. Purchasing Guide (Rechargeable Waterproof AI Toys Version)

　　For Kids' Toy Needs: Prioritize choosing "magnetic/wireless charging (safe and waterproof) + long battery life (over 4 hours)"; pay attention to charging protection functions (power cutoff after overcharging) and avoid small parts falling off

　　For Adult Use Needs: Focus on "fast charging (full charge within 2 hours) + sealed charging port/wireless charging + APP battery monitoring"; also consider floating stability (e.g., anti-tipping is required for pool use)

　　For Pet Companionship Needs: Focus on choosing "wireless inductive charging (chew-resistant) + waterproof battery film + battery life over 8 hours"; support AI sleep power-saving to reduce the trouble of frequent charging
