Problems solved by technology

[0004] The air flow of the blower equipped with a centrifugal fan is small, which will increase the working time of the blower during the cleaning process, resulting in a shortened working life of the blower
And when the blower is working, the inhaled leaves will block the fan due to their large volume when they pass through the fan, thus affecting the work of the blower.

Embodiment Construction

[0023] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as Figure 1-Figure 3 As shown, in one embodiment, a blower includes a main body housing 10 and a motor 40 disposed on the main body housing 10, and an air cavity 20 is formed in the main body housing 10, and the air cavity 20 is An axial flow fan 30 is arranged in the axial direction; the motor 40 is connected and drives the axial flow fan 30 through a transmission mechanism;

[0025] The above-mentioned blowing machine, in the blowing state, is arranged on the motor 40 of the main body casing 10 to run, and drives the axial flow fan 30 connected with it through the transmission mechanism to rotate at a high speed, forming a high-speed airflow in the wind chamber 20, and blowing the air on the ground. Leaves or dust gather; when the blower is in the suction state, the negative pressure generated by the high-speed operation of the...

Abstract

The invention discloses a blower-vacuum. The blower-vacuum comprises a main machine shell and a motor arranged on the main machine shell, an air cavity is formed inside the main machine shell and an axial fan is axially arranged inside the air cavity; the motor is connected through a transmission mechanism and drives the axial fan; a smashing mechanism is formed between an air inlet of the air cavity and the axial fan. An axial fan of a large air volume is utilized, due to the fact that axial fan is axially arranged inside the air cavity and the central axis of the air cavity is linear, effects of air blowing and suction are enhanced and the air utilization rate is improved; meanwhile, leaves and dust are smashed by the smashing mechanism before being sucked into the air cavity, the volumes of the leaves and the dust become smaller and accordingly axial fan blocking caused by relatively large volumes of the sucked leaves or dust can be avoided, and the work efficiency of the blower-vacuum is improved.

Description

technical field [0001] The present invention relates to a hand-held operating device, in particular to a blower and suction machine for gardening. Background technique [0002] The blower is an outdoor cleaning tool, mainly used for cleaning and collecting fallen leaves, so it is also called a leaf blower. [0003] Generally, the fan of the blower uses a centrifugal fan with high wind pressure. When the blower is in the blowing mode, the high-speed airflow blown from the suction pipe will gather the leaves scattered on the ground; When the suction machine is in the suction mode, under the high-speed rotation of the centrifugal fan, the suction airflow is formed to suck the leaves and dust on the ground and enter the collection device to complete the cleaning of the leaves on the ground. [0004] The air flow rate of the blower equipped with a centrifugal fan is small, and the working time of the blower will be increased during the cleaning process, resulting in a shortened ...
