Blowing suction machine

Abstract

The invention relates to an electric tool for environmental care in daily life, in particular to a blowing suction machine. The blowing suction machine comprises a volute with an air inlet and an airoutlet, an air outlet pipe in seal connection with the air outlet, an air tube communicating with the volute, a handle, a trigger, a motor, a power source component and a centrifugal air fan, whereinthe handle, the trigger, the motor and the power source component are arranged outside the volute, the centrifugal air fan is inside the volute, when the handle is held by hands to pull the trigger, the motor is electrically connected to the power source component, and the centrifugal air fan is driven to rotate, air enters the volute through the air inlet and is compressed to the air outlet pipeby the air fan, the centrifugal air fan is composed of a panel, a bottom plate and a plurality of spiral blades, and the volute is internally provided with a sealing rib with the circle center being same as the panel and the inner diameter being larger than the panel diameter. By means of the blowing suction machine, noise can be greatly reduced, and the compression efficiency is improved.

Description

technical field [0001] The invention relates to an electric tool for environmental care in daily life, in particular to a blower, which includes a volute, a motor, an air outlet pipe and a centrifugal fan. Background technique [0002] Hair dryers are necessary electric tools for environmental care in daily life, such as blowing off fallen leaves, grass and other dust and debris outdoors; due to the large flow and wind speed required, the volume and noise of the machine itself are relatively large. As an improved product of the hair dryer, the blower is a dual-purpose electric tool for blowing or sucking used in a small space or a large space. For a large space, the efficiency of suction is relatively low, so the blowing method is used. [0003] Existing blower generally comprises the volute that has air inlet and air outlet, the handle that links to each other with volute, trigger, power assembly, motor, air outlet pipe and centrifugal fan, and motor is perpendicular to vo...

AI Technical Summary

Problems solved by technology

[0004] However, the existing blower has the defects of high noise and low compression efficiency; the noise will seriously damage the user's health and experience, and the low efficiency will affect the continuous working time of the product and increase the waste of materials

[0005] Moreover, the existing products can only focus on the ease of use and operating comfort in one state; generally, the ease of use and operating experience in the blowing state are emphasized; and in the state of the suction fan, the operation is very inconvenient

[0006] For blowing and suction machines, high noise and low compression efficiency are stubborn problems in the industry. How to achieve high-efficiency compression, low noise, and easy operation and use in both blowing and suction states is the goal that the industry is constantly pursuing.
