Abstract

Disclosed is an inducible jet fan comprising a shell (1), wherein the shell (1) comprises a cylinder (11), a conical transition barrel (12) and a hemispherical cylinder (13); the right side of the hemispherical cylinder (13) is provided with a gap (14), and a jetting portion (3) is sheathed in the hemispherical cylinder (13); the jetting portion (3) comprises a ball (31) and an air outlet pipe (32) that are integrally formed, the air outlet pipe (32) is in communication with an inner cavity of the ball (31), an air inlet (33) is formed in the left side wall of the ball (31), and the outer wall of the ball (31) is pressed onto the inner wall of the hemispherical cylinder (13); a ball retaining ring (4) is fixed in the conical transition barrel (12); a spherical inner wall (41), matching the outer wall of the ball (31), is formed on the inner wall of the right end of the ball retaining ring (4); the ball (31) is pressed onto the spherical inner wall (41); the air outlet pipe (32) is inserted into the gap (14); and and the jetting portion (3) is provided with an angle adjusting mechanism (5). In the fan, the jetting direction of the jetting portion can be adjusted by means of the angle adjusting mechanism, the jet airflow is concentrated, and the inducible effect thereof is good.

Description

Technical field: [0001] The invention relates to the technical field of fans, in particular to an induced jet fan. 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 object of the present invention is to overcome the deficiencies of the prior art, and provide an inductive jet fan, which can adjust the spraying direction of the spraying part through an angle adjustment mechanism, and the sprayed airflow is concentrated, and the inducing effe...
