Blowing machine with electric motor with equal pressure angle logarithmic helical clamp seat

Abstract

The invention relates to a portable electric tool which is used for blowing and sucking leaves in places such as a flower bed, a courtyard, a park, a roadside and the like, in particular to a blowing-sucking machine adopting a motor with logarithmic-spiral wire clamping bases with a constant pressure angle. The improvement on the blowing-sucking machine includes: arranging a movable auxiliary handle, a dust collecting bag bracket and a tying hole; arranging a soft sheet at a dust outlet of a machine enclosure; arranging a cutting edge on a blowing impeller; arranging a fuse and double switches on a circuit; arranging sound insulating and vibration reducing materials and honeycombs inside and outside the blowing-sucking machine; changing roller wheels to be steerable; changing a single extension barrel into a multi-extension tube or a flexible foldable tube; improving coaxiality, achieving measuring dynamic balance and providing a laser aiming tool; the motor comprises a centrifugal angle carbon brush plug (118a); in order to prevent a phenomenon that phased plugging is loosened and disconnected by vibrating sometimes, a reverse centrifugal force principle is utilized, so that the phased plugging is tighter rather than more loosened with rotation; an insertion direction of single male joints of the carbon brush plug (118a) is a direction in which multiple heads face towards one side of a centripetal direction with an included angle; and the logarithmic-spiral wire clamping bases (118cx) are arranged on the carbon brush rack (118c) for clamping a wire to prevent a loosening phenomenon. The portable electric tool has been applied to volume production.

Description

technical field [0001] The invention relates to a portable electric tool for blowing and sucking leaves in places such as flower beds, gardens, parks and roads, especially a motor blowing and sucking machine with an equal pressure angle logarithmic spiral clamping seat, including a movable Auxiliary handle, improvement of dust bag bracket and binding mouth, adding soft sheet to the dust outlet of the body shell, adding blades to the blowing impeller, adding insurance and double switches to the circuit, and adding sound-absorbing and vibration-reducing materials and honeycombs inside and outside the blower and suction machine , The roller is changed to steerable, and the single extending tube is changed to a multi-extruding tube or a flexible folding tube, and the clamping seat solves the problem of preventing the carbon brush plug from shaking loose and falling off sometimes. Background technique [0002] Blowers are widely used to clean leaves in the manner chosen by people...

AI Technical Summary

Problems solved by technology

Low vibration and low noise also need to be further optimized; if consideration is given to adding vibration-reducing foam plastics outside the motor and adding shock-absorbing and sound-absorbing materials and honeycomb structures to multiple places in the blower, it will have a certain effect; The vibration and noise of the grass machine are largely rooted in the precision and shape tolerance of the power and tools. It is desirable to improve the coaxiality of the motor and the blowing impeller and measure the dynamic balance, but the pursuit of blowing and suction machines The low vibration and low noise is actually a long-standing long-standing problem
