Water Purifier Cover Assembly With Horizontal Pump-Filter Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional desktop water purifiers have a complex arrangement of filtration units and water pumps, leading to a non-compact structure and frequent refilling due to small water chambers.
Innovation Solution
A compact cover assembly with a horizontal arrangement of the water pump and connecting unit, a protruding water outlet, and a detachable filtration unit, along with a receiving chamber to house these components, ensuring a streamlined design and reduced refilling frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the filtration unit and water pump are independently installed inside the water tank, then the water channels connecting these structures become complicated, but the overall structure inside the water tank is not compact enough
Solution Approach 1:
The patent integrates the water pump and filtration unit into a single integrated assembly that is horizontally arranged within the cover assembly. This merging of components simplifies the water channel connections and improves space utilization in the water tank, directly resolving the technical contradiction between device complexity and volume efficiency.
2Length of stationary object
If the water pump and connecting unit are arranged vertically, then the receiving chamber height increases, but the cover assembly becomes larger in overall size
Solution Approach 1:
The patent transitions from a vertical arrangement to a horizontal arrangement of the water pump and connecting unit within the receiving chamber. This dimensional change allows the components to be disposed side-by-side rather than stacked, reducing the receiving chamber height and minimizing the cover assembly's overall footprint while maintaining functional integrity.
3Ease of operation
If the water outlet is positioned at the top of the water tank, then water dispensing requires lifting the tank, but the design becomes less user-friendly
Solution Approach 1:
The patent positions the water outlet at the bottom of the cover assembly, allowing purified water to flow downward by gravity. This spatial repositioning eliminates the need to lift the water tank for dispensing, significantly improving ease of operation while maintaining a compact and stable water tank structure.
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
The design facilitates easy water dispensing, reduces the overall size and frequency of refilling, and allows for easy filtration unit replacement, enhancing user convenience and efficiency.
Implementation Method 1
The water pump can drive the water to flow in the water purifier
Implementation Method 2
The filtration unit can usually include various filtration materials, such as activated carbon, ultrafiltration membrane, reverse osmosis membrane, etc., to achieve different water treatments
Implementation Method 3
The water outlet protrudes from the water tank and the purified water flows downward from the water outlet

AI summary
The present application provides a water purifier comprising a water tank and a cover assembly. The cover assembly comprises a cover assembly shell defining a receiving chamber, a water suction and filtration module, and a water outlet. The water suction and filtration module comprises a water pump, a filtration unit, and a connecting unit fluidly connecting the water pump and the filtration unit. The receiving chamber is isolated from the water chamber. The water pump and the connecting unit are disposed in the receiving chamber in a substantially horizontal arrangement. The water outlet protrudes from the water tank and the purified water flows downward from the water outlet.
