AI Technical Summary
Technical Problem
Existing electric fluid jets consume a lot of power when using battery power, resulting in a short battery life and making it impossible to work for a long time in locations where wall-mounted power is not readily available.
Method used
By employing an electric controller, the system fluid pressure of the fluid ejector is sensed, and the motor controller is supplied with operating power only when the system fluid pressure is less than or equal to a threshold pressure; otherwise, the power supply is suppressed, thereby achieving power saving.
Benefits of technology
It extends the operating time of battery-powered fluid ejectors, improves battery efficiency, and is suitable for ejection operations in various locations.

Abstract
A battery-powered fluid ejector includes a reciprocating positive displacement pump, a power supply, an electric motor, a motor controller, a user-adjustable mechanism, a pressure switch, and a power controller. The power supply includes a battery. The user-adjustable mechanism is used to set a user-adjustable pressure threshold corresponding to the system fluid pressure of the battery-powered fluid ejector. The pressure switch generates a pressure signal indicating whether the system fluid pressure is greater than the user-adjustable pressure threshold. The power controller is configured to control the power of the battery-powered fluid ejector by providing operating power to the motor controller in response to a pressure signal indicating that the system fluid pressure is less than the user-adjustable pressure threshold, and by not providing operating power to the motor controller in response to a pressure signal indicating that the system fluid pressure is greater than the user-adjustable pressure threshold.
