Problems solved by technology

At present, most common blowing machines on the market use side-by-side air intake channels and air outlet channels. The air inlet of the air intake channel and the air outlet of the air outlet channel are on the same plane. There is a relatively large relative wind speed deficit at the junction of the air inlet near the air flow channel and the air outlet of the air outlet air channel, which is easy to form eddy currents, and the wind noise is large and affects the blowing efficiency. At present, there is no relatively mature technology to solve this problem

Abstract

The invention relates to a handheld blowing suction machine with an auxiliary air cylinder. The handheld blowing suction machine comprises a machine head part (1) and an air duct (2), wherein the air duct (2) comprises an air suction cylinder (3) and an air blowing cylinder (4); and the handheld blowing suction machine is characterized in that the front end of the air blowing cylinder, (4) close to an air outlet (8) is provided with the auxiliary air cylinder (9); and the auxiliary air cylinder (9) surrounds the air outlet (8) to form an auxiliary flow channel (10). The auxiliary flow channel has the air amplification characteristics and can be used for guiding high-speed airflow to achieve higher-speed airflow, so that the air outlet airflow is amplified and blown out. The handheld blowing suction machine is simple in flow channel airflow amplification and turbulence resistance structure, low in cost, effective, reliable and suitable for most of blowing suction machines in the market.

Description

technical field [0001] The invention relates to a blowing and aspirating machine, in particular to a hand-held blowing and aspirating machine with an auxiliary air cylinder. Background technique [0002] The hand-held blower has a wide range of applications, and is suitable for household cleaning, road maintenance construction, lawn and garden cleaning, etc. At present, most common blowing machines on the market use side-by-side air intake channels and air outlet channels. The air inlet of the air intake channel and the air outlet of the air outlet channel are on the same plane. There is a relatively large relative wind speed deficit at the junction of the air inlet near the air flow channel and the air outlet of the air flow channel, which is easy to form eddy currents, and the wind noise is large and affects the blowing efficiency. At present, there is no relatively mature technology to solve this problem. Contents of the invention [0003] The object of the present inv...
