DC Gear Motors (TJZ37RQ) for Smart Toilet Seats: Smart Sanitation, Elevating Daily Comfort

The TJZ37RQ DC gear motor is a core customized drive component tailored for smart toilet seats, integrating waterproof and corrosion-resistant structural design, precision micro-gear transmission and low-voltage safety technology. Powered by 12V low-voltage safe power supplies (via AC-DC converters for household use), it achieves accurate position control and stable low-noise operation, supporting key smart toilet seat functions such as adjustable nozzle cleaning (front/rear movement, rotation), automatic lid lifting/closing, warm air drying and seat ring angle fine-tuning while meeting the high-humidity, sanitary, safe and quiet requirements of bathroom scenarios.

Working Principle

Smart toilet seats rely on the TJZ37RQ motor for multi-functional drive. The motor converts electrical energy into mechanical energy, driving the cleaning nozzle to move linearly (50-100mm stroke) and rotate (0-30°) via precision multi-stage gear transmission, enabling targeted cleaning with adjustable positions. For automatic lid models, it provides steady torque to control the lid/seat ring’s slow lifting and soft closing (avoiding slamming), coordinated with human body induction sensors for instant response. It also assists the warm air drying fan in adjusting air outlet direction, and supports seat ring heating zone positioning for partial temperature adjustment. Its built-in position feedback and speed regulation system ensures smooth operation—even when encountering resistance (such as accidental contact during lid movement)—without jitter or position deviation.

Core Advantages

Adaptable to the harsh bathroom environment and sanitary requirements, the TJZ37RQ boasts outstanding performance: IPX7 waterproof and corrosion-resistant design, with sealed casing and anti-rust gears to withstand high humidity, water splashes and cleaning agent erosion; ultra-precise positioning (±0.5mm) for nozzle cleaning accuracy, ensuring targeted and comfortable use; ultra-low operating noise (≤30dB) via optimized gear meshing and damping rubber, maintaining a quiet bathroom environment; low-voltage safety design (12V) with overcurrent, overheat and leakage protection, eliminating electric shock risks in wet environments; sanitary sealed structure, preventing water and dirt ingress into the motor to avoid bacterial, complying with bathroom hygiene standards; customizable torque and stroke parameters to match different smart toilet seat models (standard, elongated, wall-mounted); and long service life (≥10,000 working cycles) with wear-resistant engineering plastic gears and sealed bearings, adapting to frequent daily use.
