Problems solved by technology

But due to the need to place the safety switch and the consideration of the strength of the volute at the left and right volute tails of the existing leaf blower, the volute here is often discontinuous, and the air duct of the discontinuous volute is not smooth. It also loses the function of the volute, so that the air volume cannot meet the requirements of theoretical calculations, and the noise increases

Embodiment Construction

[0024] Such as Figure 1 to Figure 5 As shown, the leaf blower includes a volute 1, the volute 1 is connected with an air duct 2, an air duct disassembly and fixing structure is arranged between the volute 1 and the air duct 2, and the air duct in the volute 1 is provided with For the air outlet, the tail end of the air duct 2 is provided with a stepped head with a smaller diameter, which is just inserted into the air outlet after the air duct 2 is installed. The outer wall of the tail end of the air duct 2 is provided with a hinged seat 21 to be hinged with the volute 1. The hinged seat is arranged in front of the step head. A rotating shaft is provided on the hinged seat 21. A rotating shaft is provided on the volute 1 for the rotation of the air duct. The support 11 for shaft rotation is provided with a fulcrum for the rotation of the rotation shaft. The outer wall of the tail end of the air duct 2 is provided with a fixed head 22 at a circumferential interval of 180 degre...

Abstract

The invention discloses an improved structure of a leaf blowing and sucking machine. The improved structure comprises a spiral casing. The peripheral profile curve of the spiral casing is continuous at the tail of the spiral casing. The profile curve of the tail of the spiral casing is designed to be continuous, an air duct inside the spiral casing is smoother, noise is lowered at the same time, and therefore a series of problems caused by incontinuity of a spiral casing in the prior art are solved.

Description

technical field [0001] The invention relates to a leaf blower. Background technique [0002] The leaf blower is an outdoor cleaning tool, mainly used for cleaning and collecting fallen leaves. It blows away the leaves and dust on the ground by blowing air or puts the leaves into the bag by suction, and crushes the leaves before they enter the bag. [0003] Existing leaf blower generally includes volute, fan blade, motor, air pipe and control switch etc., and the fan blade that links to each other with motor is positioned at the volute air duct of volute, and it is driven by motor in the volute wind. The high-speed rotation in the tunnel breaks the leaves and other debris sucked into the room, and the broken debris is discharged from the chip outlet and collected in the garbage bag. But due to the need to place the safety switch and the consideration of the strength of the volute at the left and right volute tails of the existing leaf blower, the volute here is often discon...
