Regular maintenance is required to keep the chair in good condition. 4. **Suction System Blockages**: The integrated suction systems can become clogged, affecting their performance and requiring cleaning or replacement. 5. **Lighting Issues**: The dental light may malfunction, either becoming too dim or failing to turn on, which can hinder visibility during procedures.

Working Principle of Dental Treatment Chair and Common Issues Working Principle of Dental Treatment Chair: (1) Gas Control Main Valve and Water Control Main Valve: ① The gas control main valve and the water control main valve are operated by an air leakage switch. The working principle of both valves is the same. When the air leakage switch is turned on, the gas enters the oil circuit board and pushes the valve core. The gas pressure drives the valve core to open the sealing surface, allowing gas or water to pass through. Conversely, the control pneumatic valve is disconnected. The valve core returns to its position using spring force, disconnecting the pneumatic valve and the water supply.
