To test suction performance under different operating conditions, current technology often employs manual methods to perform complex pre-treatment tasks, including controlling the motor's operating status, plugging and unplugging the motor power supply interface, and sealing the air inlet plug. Because manual operation significantly interferes with test results, it hinders accurate and efficient data acquisition and fails to meet production needs. Utility Model Content
