AI Technical Summary
The separate design of gas and liquid power sources in existing technologies leads to bloated systems, large equipment size, and complex piping, especially in space-constrained automated equipment with high integration requirements.
The liquid pump and air pump are integrated into a pump chamber within a single housing, and operate in coordination through a unified control system. The design incorporates waterproof and breathable valves, reinforcing ribs, threaded sleeves, and other structural features to simplify the system structure and reduce complexity and potential failure points.
It significantly reduces system space and weight, making it suitable for space-constrained applications such as vehicle-mounted devices. It also reduces system complexity and potential failure points while improving overall strength and waterproof performance.
