Technical Field

[0001] The utility model relates to the technical field of blower-vacuum machine components, and more specifically, to a blower-vacuum machine head flip cover component. Background Art

[0002] The rapid development of the modern machinery industry has led to the widespread use of mechanical equipment in various industries in life. In the process of weeding by environmental workers, a blower-suction machine is needed to absorb and process the crushed grass. The equipment mainly includes a main body shell, an operating handle, a motor arranged in the shell, a fan driven to rotate by the motor, a switch for controlling the rotation of the motor, and a blowing pipe and a suction pipe connected to the main body shell. The suction pipe and the blowing pipe are fixedly connected and extend to one side of the shell. The suction pipe is provided with a main body extending along the longitudinal axis, and a bent portion bent at an angle to the extension axis of the suction pipe. The suction pipe structure is arranged in this way to make it easier and more convenient to perform one-handed operation and achieve a better dust collection effect.

[0003] The head structure of the existing blower-suction machine is relatively simple and cannot form a complete enclosed space. It is difficult to absorb and process the crushed grass inside, thereby reducing its practicality. Utility Model Content
