Abstract

The invention discloses a jet fan with adjustable spray angle, which comprises a casing and a spray head, the casing includes an integrally formed air inlet cylinder body and a first hemispherical body, the front end of the first hemispherical body is formed with a gap; The spray head includes an integrally formed second hemispherical body and an air outlet cylinder; the spherical outer wall of the second hemispherical body is attached to the spherical inner wall of the first hemispherical body, and the air outlet cylinder can be moved up and down in the gap through an adjustment mechanism. Flip. The invention can change the jetting direction of the jet fan by adjusting the angle of the jetting head, and the jetted airflow is concentrated and the induction effect is better.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a jet fan with an adjustable spray angle. Background technique [0002] Jet fan is a special axial flow fan, mainly used in the longitudinal ventilation system of tunnels such as roads, railways and subways; it can also be used in sensitive parts of semi-horizontal ventilation systems or transverse ventilation systems, such as the entrance and exit of tunnels, Play the role of inducing airflow or smoke exhaust. Under the existing technology, ordinary jet fans cannot adjust the angle, and sometimes there is a certain slope in some installation spaces, which cannot play a good guiding role. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a jet fan with adjustable jet angle, which can change the jet direction of the jet fan by adjusting the angle of the jet head, and the jetted airflow is concentrat...
