Venturi Spa Vacuum Nozzle for In-Place Dirt Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning solutions for whirlpool spa tubs are inefficient, time-consuming, require significant water waste, and are not suitable for the undulating and crevice-rich surfaces, failing to effectively remove dirt and contaminants from the bottom of the tub, which poses health and equipment risks.
Innovation Solution
A manual aquatic vacuum cleaner with a suction hose and bellows coupling that utilizes the Venturi effect for powerful suction, featuring corner and seat nozzles to clean hard-to-reach areas, eliminating the need for electrical devices and reducing water usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cleaning methods (draining, sanitizing, refilling) are used to clean the bottom of the tub, then water quality and hygiene are improved, but water consumption increases and time required increases
Solution Approach 1:
The invention extracts and removes only the dirt and contaminants from the tub bottom using a vacuum nozzle, leaving the clean water in place. This selective removal avoids the need to drain and refill the entire tub, significantly reducing water consumption while maintaining water quality.
Solution Approach 2:
The system uses the tub's own drainage system and water flow to power the vacuum cleaning process. By connecting to the drain and utilizing the water flow, the system cleans itself without requiring external power sources or additional water input.
2Reliability
If traditional cleaning methods (draining, sanitizing, refilling) are used to clean the bottom of the tub, then water quality and hygiene are improved, but time required increases
Solution Approach 1:
The vacuum nozzle directly extracts dirt from the tub bottom in place, eliminating the need for time-consuming draining, sanitizing, and refilling operations. This targeted cleaning approach reduces the overall cleaning time from hours to minutes.
Solution Approach 2:
The system maintains continuous cleaning action by using the water flow through the hose to continuously generate suction and move dirt particles into the collection container, allowing for efficient and uninterrupted cleaning of the tub bottom.
3Power
If electric vacuum cleaners with motors and pumps are used, then cleaning power is improved, but device complexity increases
Solution Approach 1:
The invention uses hydraulic principles by utilizing the water flow itself to generate the suction force. The moving water creates a pressure differential that draws dirt particles into the vacuum nozzle and into the collection container, eliminating the need for electric motors or mechanical pumps.
Solution Approach 2:
The system is self-powered by the water flow from the tub's drainage system. The kinetic energy of the flowing water is converted into suction force, making the device independent of external power sources and significantly simpler in construction.
4Reliability
If the tub is completely drained for cleaning, then dirt removal is improved, but water waste increases
Solution Approach 1:
The vacuum nozzle selectively extracts only the dirt and contaminants from the tub bottom while leaving the clean water in place. This targeted extraction ensures thorough dirt removal without the need to drain the entire tub, preventing water waste.
Solution Approach 2:
The cleaning action is localized to the tub bottom area where dirt accumulates. The vacuum nozzle concentrates its suction force on the bottom surface, ensuring effective dirt removal from this specific region without affecting the overall water volume in the tub.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Efficiently cleans the whirlpool spa tub in minutes, saving water and time, while being durable and cost-effective, without requiring maintenance or electrical components.
Implementation Method 1
strong suction, intensified by the Venturi effect resulting from the pressure of the open drain drain in relation to the narrowing of the vacuum hose

AI summary
A manual water vacuum cleaner for cleaning a whirlpool spa bath or similar, comprising a suction hose with an end receiving a quick-connect adapter for coupling a corner vacuum nozzle or seat vacuum nozzle and the opposite end with a spigot coupling for assembling the accordion coupling, which can be coupled to the drainage drain of water evacuation of the hydromassage spa bath. The accordion coupling in the drainage drain, once open and suction between the diametrical narrowing provided between the drainage drain and hose configures the Venturi effect to suck up dirt accumulated on the sides, seats and bottom of the hydromassage spa bath.
