Bathtub Bubble Generator External Pump Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bathtubs with micro-nano bubble generating devices face complexity and high costs due to the need for a separate air pump, which is costly and difficult to install, maintain, and replace.
Innovation Solution
A bathtub design where the water pump is mounted on the outer side of the bathtub body side plate, and the bubble water generating device uses negative pressure to mix air into a flow channel, eliminating the need for a separate air pump, simplifying the structure and reducing size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate air pump is used to supply air for micro-nano bubble generation, then bubble water production is achieved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent merges the air supply function into the water pump by integrating an air inlet directly into the water pump body. The air inlet is positioned to communicate with the impeller chamber, allowing air to be drawn in during impeller rotation. This eliminates the need for a separate air pump and complex air supply piping, while still achieving reliable micro-nano bubble generation through the high-speed rotating impeller.
2Reliability
If a separate air pump is installed, then air supply for bubble generation is ensured, but installation and maintenance difficulty increase
Solution Approach 1:
The air inlet is integrated directly into the water pump housing, positioned to communicate with the impeller chamber. This integration eliminates separate air supply components and piping, making the entire bubble generation system part of the water pump assembly. Consequently, installation requires only mounting the water pump, and maintenance involves servicing the water pump as a single unit, greatly improving operational convenience.
3Reliability
If the bubble generating device is mounted at the bottom of the bathtub, then bubble generation is achieved, but disassembly and maintenance become inconvenient
Solution Approach 1:
The patent segments the bubble generation function from the bathtub structure by mounting it on the water pump, which is installed externally on the bathtub wall. The air inlet communicates with the impeller chamber through internal passages in the water pump housing. This segmentation allows the entire bubble generation system to be accessed and serviced by simply removing the water pump from its external mounting position, without requiring disassembly of the bathtub or access to internal spaces.
4Reliability
If a separate air pump is used, then air supply is ensured, but cost increases
Solution Approach 1:
The patent combines the air supply function with the water pump by integrating an air inlet directly into the water pump housing. The air inlet communicates with the impeller chamber, allowing air to be drawn in during operation. This merger eliminates the need for a separate air pump purchase and installation, reducing overall system cost while maintaining reliable air supply capability through the high-speed rotating impeller that naturally draws air into the water stream.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy installation, disassembly, and maintenance of the bubble water generating device, reducing costs and complexity while maintaining effective bubble water production for cleaning and sterilization.
Implementation Method 1
The bubble water generating device adsorbs air into a mixing flow channel by negative pressure
Implementation Method 2
The intake air is mixed and flows with the water, eventually forming a bubble water

AI summary
A bathtub comprises a bathtub body, a water pump mounted on an outer side of a bathtub body side plate of the bathtub body, and a bubble water generating device mounted on the bathtub body side plate. The bathtub body side plate is provided with a side plate water outlet hole. A first water pipe is connected between the side plate water outlet hole and a water inlet of the water pump. A second water pipe is connected between a water outlet of the water pump and the bubble water generating device. A device water inlet in communication with the mixing flow channel is provided at one end of the device main body. A radius of the device water inlet is greater than a radius of the mixing flow channel.
