Spray Washing Component Transmission for Smart Toilet Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart toilet covers have a large overall volume and poor aesthetics due to the placement of the motor near the nozzle, which affects their service life and thickness, leading to inconvenience and inefficiency in space usage.
Innovation Solution
A spray washing component design featuring a base, nozzle, and dual motors with a transmission structure using a conveyor belt and dual transmission gears, where the first motor is placed away from the nozzle, and a water diversion unit with hoses and a self-cleaning connector, along with a wire harness structure to maintain hose alignment and prevent entanglement, allowing for compact and precise operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the motor is placed close to the nozzle to drive the nozzle displacement, then the nozzle can be driven effectively, but the overall thickness of the smart toilet cover increases and aesthetics deteriorate
Solution Approach 1:
A transmission structure comprising a driving gear, dual transmission gear, and conveyor belt is introduced as an intermediary mechanism between the motor and nozzle. The motor drives the driving gear, which transmits power through the conveyor belt to the dual transmission gear, ultimately moving the nozzle along the sliding track. This intermediary transmission system allows the motor to be positioned away from the nozzle, reducing the overall thickness while maintaining effective driving capability.
2Device complexity
If the motor is placed close to the nozzle, then the driving mechanism is compact, but the motor is easily damp and damaged by the jet, reducing service life
Solution Approach 1:
The motor is extracted from its traditional position near the nozzle and relocated to a position away from the jet. The transmission structure (driving gear, dual transmission gear, and conveyor belt) serves as the connecting mechanism, allowing the motor to be positioned in a drier environment while still effectively driving the nozzle. This separation protects the motor from water damage and dampness, extending its service life.
3Volume of stationary object
If hoses are arranged closely to save space, then the base volume is reduced, but the hoses may entangle during nozzle movement
Solution Approach 1:
The hoses are arranged in different spatial dimensions and orientations within the base. The curved section of the first hose is positioned on the outer side of the curved section of the second hose, creating a three-dimensional arrangement that prevents entanglement. This spatial arrangement allows the hoses to move smoothly with the nozzle while maintaining a compact base volume.

Function Achieved in This Case
The solution reduces the overall thickness of the smart toilet cover, enhances its aesthetics, and provides multiple rinsing functions while ensuring smooth operation and easy maintenance, with a compact and efficient design that prevents hose entanglement and motor damage.
Implementation Method 1
The conveyor belt is disposed around the driving gear and the dual transmission gear. The first motor drives the driving gear to rotate and links the dual transmission gear to rotate through the conveyor belt
Implementation Method 2
The nozzle has a rack cooperating with the first motor. The first motor drives the nozzle to slide along the base through the transmission structure
Implementation Method 3
The nozzle has a rack cooperating with the first motor. The dual transmission gear respectively meshes with the conveyor belt and the rack on the nozzle

AI summary
A spray washing component for a smart toilet cover and an assembly method thereof are provided. The spray washing component includes a base, a nozzle, and a first motor. A sliding track is disposed on the base. The nozzle has a rack cooperating with the first motor. The first motor drives the nozzle to slide along the base. The first motor is installed at an end away from a jet of the nozzle and drives the nozzle to be displaced through a transmission structure. The transmission structure includes a driving gear, a dual transmission gear, and a conveyor belt. The driving gear is in anti-rotation cooperation with an output shaft of the first motor. The dual transmission gear respectively meshes with the conveyor belt and the rack on the nozzle. The spray washing component and the assembly method solve the large space occupation and insufficient aesthetics of the existing toilet.
