Problems solved by technology

The stator part of the outer rotor motor of the ordinary brushless motor that is usually used for blower or leaf blower is outside the motor. The stator is large and the lower slot of the stator winding is large, which does not meet the expectation of light weight and high output; especially its The rotor part with windings has to protrude a very long and thin motor output shaft, and the connection between the motor and the impeller fan can only be realized on the long extension line outside the axial direction of the motor, which causes a fatal problem Problem, the output shaft between the motor and the impeller fan forms a material mechanics cantilever beam structure, the length of the output shaft between the motor end and the center of the impeller fan is the moment arm, the radial centrifugal force on the impeller fan This force arm and the bias force form a large harmful bias moment, which consumes a large amount of motor output, unnecessarily increases the deflection of the shaft and the moment of inertia, and restricts the high-speed strength of the blower or leaf blower. out of the wind

Embodiment Construction

[0199] The operation walker selects the leaf blowing and sucking machine according to liking and habit, preferably wears protective glasses and a mask, and also uses shoulder strap 43 to be set on the shoulder and on the casing; pull out the telescopic tube of blowing and sucking, adjust the rotating speed, adjust Auxiliary handle; check the power supply, connect enough long power cords, check the insurance again, follow the instruction manual, try to open it, check that there are no broken glass and wires in the area with leaves, and use the leaf blower to do it under safe conditions, and at the same time Pay attention to the weather and rain.

[0200] The specific implementation mode that the present invention takes to solve its technical problem is explained in detail again below:

[0201]Because of the improvement of a low-vibration leaf blowing machine, including the addition of a movable auxiliary handle, the improvement of the dust bag bracket and the opening, that is, ...

Abstract

A blade blowing machine for update product noise reduction and provided with lithium battery drive motor circumferential parallel filtering noise elimination air pipes has the beneficial effects that the machine can better adapt to noise reduction frequency characteristics, at least one filtering noise elimination air pipe 61 in the longitudinal direction of a rear air cylinder is arranged between a motor and a front flow dividing cone head 52 and between the circumference of a flow dividing cone 58a and the rear air cylinder in a parallel manner, noise elimination partition boards 62 are arranged on the position, between the circumference of the flow dividing cone 58a and the rear air cylinder 58, of the cross section, and therefore the filtering noise elimination air pipes 61 in the longitudinal direction of the rear air cylinder can be conveniently mounted, multiple noise reduction holes 60 are formed in the filtering noise elimination air pipes 61, the air cylinder and a noise elimination device are combined into one to make a product, and the effect speaks for itself.

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 roadsides, especially an improvement of a low-vibration leaf blowing and sucking machine, including the addition of a movable auxiliary handle and a dust bag holder And the improvement of the tie mouth, the dust outlet of the main body shell is added with a soft piece, the blowing impeller is added with a blade, the circuit is added with an insurance and a double switch, and the inside and outside of the blower and suction machine are equipped with sound-absorbing and vibration-reducing materials and honeycombs, and the rollers are changed to steerable. And on the basis of the low-vibration leaf blower with the safety door of the equal logarithmic spiral at the pressure angle, the improved leaf blower with the lithium battery drive motor and the filter and noise reduction air duct parallel to the circumference.
