Portable Teeth Cleaner with Integrated Reservoir and Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional teeth cleaning apparatuses face inconvenience due to the need for connecting hoses during use and water leakage issues during water injection in their water reservoirs.
Innovation Solution
A portable teeth cleaning apparatus with a fixedly connected liquid reservoir and teeth cleaner body, featuring a check valve, changeover valve, and pump that allows for automatic water injection and avoids leakage by creating negative pressure within the reservoir, eliminating the need for external hoses and manual water injection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a water tank and pump are used to transmit water to the teeth cleaner, then water can be supplied to the teeth cleaner, but connecting hoses are required all the time which restricts user movement and causes inconvenience
Solution Approach 1:
The patent extracts the water storage function from a separate water tank into a built-in water reservoir within the teeth cleaner body. This eliminates the need for external connecting hoses between a separate water tank and the teeth cleaner, allowing users to move freely during operation while maintaining water supply capability through the integrated reservoir design.
2Ease of operation
If a built-in water reservoir is used in the teeth cleaner, then connecting hoses are eliminated, but water injection is inconvenient and leaks easily due to small injection ports
Solution Approach 1:
The patent introduces an automatic water injection system that operates in a different dimension from manual injection. The pump system automatically draws water from the water reservoir through an injection port and delivers it to the ejector, eliminating the need for users to manually inject water. This automated process prevents leakage by controlling water flow through mechanical pumping rather than manual pouring through small ports.
3Quantity of substance
If manual water injection through a small port is used, then the water reservoir can be refilled, but water leaks easily causing waste
Solution Approach 1:
The patent implements a self-service water injection system where the pump automatically draws water from the water reservoir and delivers it to the ejector without user intervention. The system monitors water levels and automatically replenishes water as needed, eliminating manual injection operations and preventing leakage by controlling the entire water transfer process through sealed mechanical pumping action.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and leak-free operation by allowing the teeth cleaner to be seated or unseated without hoses, with automatic liquid supplement and charging, reducing costs and weight through integrated sensors, and enhancing liquid ejection efficiency.
Implementation Method 1
During liquid supplement for the liquid reservoir, the pump forms a negative pressure in the inner cavity of the liquid reservoir body
Implementation Method 2
The liquid reservoir body is provided with a check valve, and the check valve is opened during liquid supplement for the liquid reservoir
Data Source
AI summary
Disclosed is a portable teeth cleaning apparatus, which implements, through a pump in a teeth cleaner, a function of supplementing a teeth cleaning liquid from a connecting seat connected to the teeth cleaner. Therefore, it is no longer necessary to connect the teeth cleaner to a teeth cleaning liquid source through a connecting hose during teeth cleaning, and liquid leakage is avoided during liquid supplement. Further, a seating/unseating status and whether a liquid reservoir is filled up are detected automatically, and a controller controls on/off and switching of a series of valves, thereby implementing automatic liquid supplement of the teeth cleaner.
