Blowing and sucking machine

Abstract

The invention provides a blowing and sucking machine. The blowing and sucking machine comprises a main machine shell, a motor located in the main machine shell, a fan capable of rotting under the driving of the motor, a dust discharge pipe and an exhaust inlet both connected with an air channel of the fan, a connecting pipe connected with the dust discharge pipe, and a leaf collection bag connected with the connecting pipe and used for storing slag, wherein one of the dust discharge pipe and the connecting pipe is provided with a connecting part and a limiting part while the other one is provided with a hook; one end of the connecting part is provided with a first bended hook; the connecting part is rotationally connected with one of the dust discharge pipe and the connecting pipe; after the connecting pipe and the dust discharge pipe are mutually connected in a sleeved manner, the connecting part rotates until the first bended hook of the connecting part is hooked with the hook; the limiting pat limits motion of the connecting part. The connecting pipe and the dust discharge pipe of the blowing and sucking machine are fixed together through a way of mutually hooking the hook and the bended hook rather than using an elastic part, so that the disadvantage that the elastic part is breakable is overcome. Therefore, the connection and fixation between the dust discharge pipe and the connecting pipe of the blowing and sucking machine can be more reliable.

Description

technical field [0001] The invention relates to the field of garden tools, in particular to a blower. Background technique [0002] The blower is a garden tool, which includes a main body casing, a blowing suction piece detachably connected to the main body casing, a motor located in the main body casing, a fan driven by the motor to rotate, and an outlet connected to the air duct of the fan. A dust pipe, a leaf collecting bag connected with the dust outlet pipe for storing dregs, and an operating handle connected with the main body casing. When the blower works, the scattered branches, leaves, weeds, etc. are first blown together, and then they are sucked into the leaf collecting bag of the blower through the blower and adsorption parts, so that the garden, grass, etc. can be cleaned. The dust outlet pipe of the commonly used blower and suction machine is generally connected with the leaf collecting bag through a connecting pipe. One end of the connecting pipe is connecte...

AI Technical Summary

Problems solved by technology

However, the elastic part of this connection method, here is the elastic hook, is easy to break, thus losing the connection and fixing effect

Therefore, the connection and fixation between the dust outlet pipe and the connecting pipe of the blowing machine adopting this connection and fixing method is not very reliable.
