TJZ25RB DC Gear Motor for Smart Trash Cans: Micro Precision Drive, Effortless Sealing for a Clean Space

The TJZ25RB DC gear motor is a customized micro core drive component tailored for smart trash cans, integrating low-torque precise actuation, slow-speed stable transmission and fully sealed waterproof and dustproof design. Powered by 3.7V/6V/12V low-voltage power supplies (compatible with dry battery and rechargeable lithium battery dual power modes), it achieves smooth linear reciprocating motion and stable rotary drive, supporting the core intelligent functions of smart trash cans such as infrared induction automatic cover opening/closing, touchless foot sensor flipping, slow closing anti-pinch and cover sealing reset for household, office, kitchen and bathroom scenario applications. It meets the stringent requirements of smart trash cans for actuation precision, silent operation, low power consumption and long standby life in wet, dusty and high-frequency use indoor environments.

Working Principle

Smart trash cans rely on the TJZ25RB motor as the core power source for the precise mechanical actuation of the cover mechanism—the key to realizing touchless intelligent operation and safe anti-pinch use. The motor converts electrical energy into uniform low-speed mechanical rotation via its optimized multi-stage precision micro-gear reduction system, and cooperates with the internal connecting rod, gear rack or torsion spring transmission mechanism of the trash can to convert rotary motion into smooth linear or angular motion of the cover (opening/closing angle 0-90°). When the infrared induction module or foot sensor detects a valid human body signal, the control board triggers the motor to start, driving the trash can cover to open slowly and stably at a customized low speed (5-15 RPM) with no sudden jitter; after the induction signal disappears (delay 3-5s), the motor reverses to drive the cover to close slowly, and the built-in torque sensing module realizes anti-pinch protection—when the cover encounters an obstacle during closing, the motor automatically stops and reverses to open the cover, avoiding pinching hands (especially children's hands) or damaging the cover structure. For the sealing reset function, the motor's precise stroke control ensures the cover is fully closed and buckled in place after closing, preventing odor leakage from the trash can and maintaining a clean indoor environment.

Core Advantages

Adapted to the intelligent touchless operation characteristics and multi-scenario use environment of smart trash cans, the TJZ25RB motor features a perfect balance of micro precision drive, silent operation and scenario adaptability, with outstanding performance advantages:

1. Ultra-compact mini design, perfect for internal integration: Body diameter ≤25mm, ultra-lightweight structural optimization (weight ≤30g), matching the narrow internal space of smart trash cans (including small desktop and large floor-standing models); the slim output shaft and flexible installation interface design fit various cover transmission mechanisms, without occupying extra internal storage space of the trash can.

2. Precise low-torque actuation, stable cover opening/closing: Customizable output torque (0.2-1.0N·m), calibrated to the load of the trash can cover and transmission mechanism, realizing slow and smooth opening/closing of the cover without sudden jitter or stuck; precise stroke control ensures the cover opens to the standard angle and closes in place, avoiding incomplete closing and odor leakage.

3. Ultra-silent operation (≤28dB), no disturbance to daily life: Optimized high-precision micro-gear meshing, food-grade silent lubricating oil and shock-absorbing rubber damping structure, the motor runs with almost inaudible noise during actuation; the slow-speed transmission of the cover mechanism eliminates the impact noise of fast opening/closing, suitable for quiet environments such as bedrooms, offices and baby rooms.

4. Dual power supply compatibility & ultra-low power consumption: Supports 3.7V/6V rechargeable lithium battery and 6V/12V dry battery (AA/AAA) dual power supply modes, meeting the design needs of different smart trash can models; working current ≤40mA during actuation, standby current close to 0μA, a set of dry batteries can support ≥6 months of use, and a rechargeable lithium battery can be used for ≥3 months on a single charge, avoiding frequent power replacement/charging.

5. IPX5 waterproof & dustproof, adapted to wet/dusty scenarios: Adopts fully sealed casing, waterproof shaft seal and dustproof bearing design, effectively isolating water splashes, kitchen oil fume, domestic garbage dust and humid air in bathrooms/kitchens; preventing water and dust from entering the motor interior and causing short circuit or gear jamming, ensuring stable operation in harsh use environments.

6. Intelligent anti-pinch torque protection, safe for family use: Built-in torque overload sensing and automatic reverse protection module, when the cover encounters an obstacle (hand, toy, tableware) during closing, the motor immediately stops output and reverses to open the cover, fundamentally avoiding pinching risks, and is safe for families with children and the elderly to use.

7. Wear-resistant & durable, adapt to high-frequency use: Adopts high-strength engineering plastic gears, reinforced copper core rotor and wear-resistant miniature bearings, resisting abrasion caused by long-term low-speed rotation and dust/oil erosion; service life ≥50,000 actuation cycles, matching the daily high-frequency use requirements of smart trash cans (≥10 times of opening/closing per day).

8. Wide temperature adaptation, stable operation in all seasons: Operating temperature range (-20℃ to 60℃), with low-temperature resistant winding and anti-oxidation internal components, ensuring stable actuation of the cover mechanism in cold winter and hot summer without performance degradation such as stuck or slow speed.
