Adjustment Device for Rod-Shaped Spray Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-electric toilet covers lack control over the extension and positioning of the rod-shaped spray unit for cleaning different areas, requiring multiple units or nozzles and complicating the internal structure, while failing to accommodate physical differences between users.
Innovation Solution
An adjustment device with a base, rod-shaped injection unit, and water supply line, featuring a toothed strip, gears, and a manual adjustment mechanism that allows for rotational control of the rod-shaped injection unit and flow valve, enabling user-adjustable water spray positions without altering the internal structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different water spray nozzles are used on the rod-shaped spray unit for cleaning the buttocks and female genital area, then the cleaning function for different areas is improved, but the internal structure of the rod-shaped spray unit becomes complicated and miniaturization is hindered
Solution Approach 1:
The rod-shaped spray unit is made dynamically adjustable in its longitudinal position along the water supply line. By allowing the spray unit to move to different positions rather than having fixed multiple nozzles, the system can adapt to different cleaning needs while maintaining a simple internal structure with only one water supply line.
Solution Approach 2:
A single rod-shaped spray unit serves multiple functions by being positionable at different locations along the water supply line. The same spray unit can clean both the buttocks and female genital area by adjusting its position, eliminating the need for separate nozzles or spray units for different areas.
2Device complexity
If the rod-shaped spray unit structure is simplified to a single water supply line, then the internal structure complexity is reduced, but the ability to adjust water spray position for different users is lost
Solution Approach 1:
The system introduces dynamic adjustability by allowing the rod-shaped spray unit to be manually positioned at different locations along the water supply line. This manual positioning capability provides adaptability for different users and cleaning needs while maintaining the simplicity of a single water supply line structure.
Solution Approach 2:
The water supply system is segmented into multiple possible connection points along the line, allowing the spray unit to be connected at different positions. This segmentation enables position adjustment without requiring multiple complete water supply lines, thus maintaining structural simplicity while achieving adaptability.
3Measurement precision
If electric motor is used to drive the rod-shaped spray unit extension and retraction, then the control precision for extension distance is improved, but the device complexity and cost increase
Solution Approach 1:
The system uses the water flow itself to drive the extension and retraction of the rod-shaped spray unit. The water pressure and flow provide the necessary force for movement, eliminating the need for external electric motors or complex drive mechanisms. The spray unit can be positioned by controlling water flow to the appropriate connection points along the supply line.

Function Achieved in This Case
Enables precise manual adjustment of water spray positions for both buttocks and female intimate area cleaning without additional internal complexity, accommodating user variations and simplifying the device's structure.
Implementation Method 1
a toothed rack is arranged on the housing of the rod-shaped injection unit in the longitudinal direction thereof, further comprising a first gear meshing with the toothed rack and a rod-shaped injection unit adjustment link which rotatably drives the first gear
Implementation Method 2
a toothed rack is arranged on the housing of the rod-shaped injection unit... a first gear meshing with the toothed rack
Implementation Method 3
In the case of non-electric toilet covers, the drive for extension and retraction is carried out by the thrust of the water flow

AI summary
The invention relates to an adjustment device for a rod-shaped spray unit of a non-electric toilet seat, comprising a base, a rod-shaped spray unit, and a water supply line for the rod-shaped spray unit, wherein the rod-shaped spray unit is connected to the base and can perform reciprocating movements in its longitudinal direction on the base. A toothed rack is provided on the housing of the rod-shaped spray unit in its longitudinal direction. Furthermore, a first gear meshing with the toothed rack and an adjustment connection for the rod-shaped spray unit, which drives the first gear, are included.The adjustment mechanism for the wand-shaped spray unit is attached to the base, with the first gear fixed at one end of the mechanism, while the other end extends beyond the side of the base. The outer end of the adjustment mechanism extends beyond the side of the base. By manually operating the adjustment mechanism, the first gear can be rotated, thus controlling the movement of the wand-shaped spray unit. In non-electric mode, this allows the water spray position of the wand-shaped spray unit to be adjusted for cleaning the buttocks or the female intimate area.
