Problems solved by technology

[0005] Whether it is the blowing and suction pipes with independent air flow channels or the blowing and suction pipes with a single air flow channel, certain safety regulations must be met in the length design, that is, the setting of the blowing and suction pipes must meet a certain length standard, especially for blowing and suction pipes. 1. The suction pipe is a blowing and suction machine with straight pipes. The length of the blowing and suction pipe is often out of proportion compared to the main body shell, which affects the overall appearance. It is not easy to carry a long blowing and suction pipe during blowing and suction work. The center of gravity is not easy to grasp, and the operation is very inconvenient

Embodiment Construction

[0042] The disclosure of the present invention discloses a portable blowing and aspirating machine that can be operated with one hand. The blowing and aspirating machine can be switched between two different working modes of blowing and inhaling. The operator only needs to make simple and quick adjustments to quickly realize Blow-suction conversion can also facilitate the cleaning and maintenance of the fan and volute, and can ensure that the blower-suction machine can work in a safe state in both blowing and suction working modes, and it is extremely convenient to assemble, light in structure and easy to operate .

[0043] Referring to Fig. 1 and Fig. 2, the blower 1 is provided with a main body casing 2, which includes a motor casing 2a accommodating a motor 3 and a volute 2b accommodating a fan 4, and the impeller of the fan 4 has an effect on the leaves under high-speed rotation. The function of crushing, the motor casing 2a is fixedly connected with the volute 2b, the rea...

Abstract

The present invention relates to a portable blowing-drawing machine which can be operated by a monolever, and comprises a host shell, an operating handle, a motor arranged in the shell, a fan which is driven by the motor to rotate, a switch for controlling the rotation of the motor, a blowing pipe connected with the host shell and a drawing pipe. The drawing pipe and the blowing pipe are fixedly connected and extend towards one side of the shell; the drawing pipe is provided with a main body part extending along a longitudinal axial line and a bending part which bends at a certain degree with the extending axial line of the drawing pipe; the structure of the drawing pipe ensures the monolever operation becomes easier and more convenient with good effect of dust collection.

Description

technical field [0001] The invention relates to a hand-held operating device, in particular to a portable blower. Background technique [0002] In the existing garden type blower and suction machine, there are usually two ways to set up the blowing and suction pipes. One is that the blowing pipe and suction pipe connected to the housing of the main engine are respectively provided with independent airflow channels, and the housing is provided with a switch The mechanism can effectively close the dust outlet or the blowing port, so as to realize the conversion between the blowing mode and the suction mode; the other is to set only a single airflow channel in the blowing and suction pipe, that is, two different working modes of blowing and suction The same airflow channel is used below, the air inlet is provided on the housing, and the air inlet is effectively opened or closed through a certain mechanism, and the blower can switch between the blowing mode and the inhalation mo...
