AI Technical Summary

⚠Technical Problem

Existing pneumatic massage beds cannot guarantee safety and reliability in the event of a power outage or solenoid valve malfunction, resulting in poor massage effects or potential safety hazards.

⚗Method used

The control system consists of a pressure reducing valve, normally closed and normally open two-position three-way solenoid valves, two-way solenoid valves, and flow regulating valves. The movement of the cylinder piston rod is controlled by switching different solenoid valves, and the piston rod is guaranteed to move to a safe position by utilizing the air supply reserve in the event of a power outage or malfunction.

🎯Benefits of technology

In the event of a power outage or solenoid valve malfunction, the cylinder piston rod can safely move upward to a safe position, ensuring that the person being massaged can smoothly detach from the massage bed, thus improving the safety and reliability of the massage bed.
