Pool Pump Air-Release Knob With Buoy-Actuated Vent Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool pumps face issues with air trapping, which disrupts liquid flow and can damage the impeller or pump, and require manual operation of relief valves that are prone to failure over time, leading to potential replacement of the entire unit.
Innovation Solution
A pool pump system with an automatic air release mechanism using a buoy and seals to isolate and vent air without manual operation, featuring a buoy room valve and seals that adjust based on fluid levels to control air and liquid flow, and a knob for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual relief valve with screw is used to release air, then air can be vented from the pump, but the screw may be stuck, cross-threaded, or degrade over time requiring replacement of the entire unit
Solution Approach 1:
The system uses a buoy that automatically rises when air accumulates in the pump, triggering the relief valve to open without manual intervention. The buoy's natural buoyancy provides the actuating force, making the system self-regulating and eliminating the need for manual screw operation.
Solution Approach 2:
The manual screw mechanism is replaced with a buoyancy-based automatic actuation system. The buoy's rise and fall mechanically trigger the valve opening and closing through a cam or lever mechanism, substituting the degraded screw system with a more reliable automatic system.
2Ease of operation
If a manual relief valve is used, then air can be released, but manual operation is required which reduces convenience
Solution Approach 1:
The buoy automatically detects air accumulation through its buoyancy property and triggers the relief valve without requiring user intervention. The system monitors and responds to air presence automatically, achieving full automation of the air release process.
Solution Approach 2:
The buoy provides continuous feedback about air accumulation in the pump. When air levels rise, the buoy rises and triggers valve opening; when air is expelled and water level drops, the buoy falls and closes the valve, creating a closed-loop automatic control system.
3Reliability
If traditional relief valve components are used, then air can be vented, but the number of components increases leading to more problem areas and reduced product longevity
Solution Approach 1:
The buoy, valve actuator, and sealing mechanisms are integrated into a single unified assembly. The buoy's movement directly actuates the valve through integrated mechanical linkages, reducing the number of separate components and potential failure points while maintaining the air release function.
Solution Approach 2:
The buoy serves multiple functions: it detects air accumulation, provides the actuating force for valve opening, and indicates the air release status. This multi-functionality reduces the need for separate sensors, actuators, and indicators, simplifying the overall system.

AI summary
Embodiments of the presently disclosed subject matter relate to systems and methods for a pool pump. The pool pump may comprise an impeller, an inlet for receiving a liquid, an outlet for supplying the liquid, a chamber above the impeller configured to receive air from the liquid. The pool pump may further comprise a buoy or an exhaust plug configured to release exhaust gas from within the pool pump. A seal configured to seal against a sealing surface of a top cover to seal the chamber.
