Hot Tub Wall Jet Nozzle Venturi Mixing for Dense Bubbles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hot tub wall jet nozzles suffer from air bubble dilution and instability, leading to inconsistent and weak massage experiences due to the short distance between the water and air inlets, resulting in reduced bubble density and quality.
Innovation Solution
A hot tub wall jet nozzle design featuring separate air and water inlets, with a Venturi effect to mix air and water, creating dense air bubbles for enhanced massage efficacy, using a nozzle body, core seat, and fastening structures for secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the distance between water inlet and air inlet is shortened, then the nozzle structure is more compact, but air bubbles are diluted and merged during water flow transmission, reducing bubble density and massage quality
Solution Approach 1:
The nozzle is divided into multiple functional components: a nozzle body with separate water inlet (110) and air inlet (120), a core seat (200) with water flow channel, and a nozzle cover (220). This segmentation allows the water and air to be introduced separately and mixed at the optimal location, preventing premature mixing and bubble dilution while maintaining a compact overall structure.
Solution Approach 2:
The core seat air hole (130) acts as an intermediary channel that guides air from the first air accommodating cavity to the second air accommodating cavity, ensuring controlled air delivery to the mixing point. This intermediary structure prevents direct short-circuiting of air and water, maintaining bubble integrity.
2Quantity of substance
If the air injection path is lengthened, then air bubble density is improved, but the nozzle structure becomes more complex and the air injection response time increases
Solution Approach 1:
The core seat (200) is nested within the nozzle body (100), and the nozzle cover (220) is arranged at the end of the core seat body. The water flow channel is nested within the core seat, and air accommodating cavities are formed between these nested components. This nested arrangement creates a compact structure with optimized air injection path while minimizing overall complexity.
Solution Approach 2:
The design utilizes spatial arrangement in multiple dimensions: the first air accommodating cavity (300) is positioned between the nozzle body and core seat, while the second air accommodating cavity (400) is positioned between the core seat body and nozzle cover. This multi-dimensional spatial organization optimizes the air injection path without linearly increasing structural complexity.
3Volume of moving object
If the nozzle structure is made more compact, then installation space is reduced, but air bubbles may merge or disappear during transmission, affecting massage consistency
Solution Approach 1:
Different regions of the nozzle are designed with specific functional qualities: the nozzle body provides structural housing, the core seat creates controlled flow channels, and the nozzle cover seals the mixing point. This localized functional design ensures that each component contributes to maintaining bubble integrity while achieving compact dimensions for installation.
Solution Approach 2:
Air is pre-accommodated in the first and second air accommodating cavities before mixing with water, ensuring that air is ready for immediate injection at the optimal moment. This preliminary air positioning prevents bubble merging and disappearance during transmission, maintaining massage consistency in a compact design.

AI summary
A hot tub wall jet nozzle includes a nozzle body and a nozzle core seat. Water flows from the water inlet into the water flow channel in the nozzle body. Air enters through the air inlet of the nozzle body and reaches the first air accommodating cavity, then flows from the first air accommodating cavity to the second air accommodating cavity, and the air from the second air accommodating cavity is then mixed with the water in the nozzle core seat at the water outlet under the Venturi effect, and the mixed water and air flow is finally discharged through the water outlet. This structural arrangement allows for reduced dilution and loss of air bubbles during water flow transmission. The Venturi effect produced in this nozzle is capable of generating a greater volume of air ejection, thus enhancing the strength and effectiveness of the massage.
