Battery Knapsack Sprayer Speed Control to Prevent Jamming and Leakage

The patent replaces the traditional mechanical valve and switch system with an electronic control system. The control module receives signals from operating members (trigger and knob) and electronically controls the motor to regulate spray flow rate and start/stop operation, eliminating mechanical jamming and leakage issues while improving ease of operation

The patent introduces a control module as an intermediary between the user's operating members and the motor. This control module processes signals from the trigger and knob, and regulates motor operation accordingly, providing smooth control without direct mechanical connection that causes jamming and leakage

The patent implements dynamic control of the motor speed through electronic regulation. The control module adjusts motor rotational speed in real-time based on user input from the knob, enabling variable spray flow rates and distances without mechanical adjustments. This dynamic electronic control simplifies the device while maintaining adaptability for different spraying needs

The patent makes the single motor-pump system universally adaptable to different spraying requirements by implementing electronic speed control. The same motor can deliver different spray flow rates and distances by varying its rotational speed through electronic control, eliminating the need for multiple mechanical components or adjustments for different liquids and distances
