Abstract

The invention discloses an induction type jet fan. The induction type jet fan comprises a shell, wherein the shell comprises a cylindrical cylinder, a transition cone cylinder and a hemisphere cylinder; a notch is formed in the right side of the hemisphere cylinder; a jetting part is connected in the hemisphere cylinder in a sleeved mode; the jetting part comprises a ball and an air outlet pipe which are integrally formed, the air outlet pipe is in communication with an inner cavity of the ball, an air inlet is formed in the left side wall of the ball, the outer wall of the ball is pressed against the inner wall of the hemispherical cylinder, a ball retainer ring is fixed in the transition cone cylinder, a spherical inner wall matched with the outer wall of the ball is formed on the innerwall of the right end of the ball retainer ring, the ball is pressed against the spherical inner wall, the air outlet pipe is inserted into the notch in an inserted mode, and the jetting part is provided with an angle adjusting mechanism. According to the induction type jet fan, the jetting direction of the jetting part can be adjusted through the angle adjusting mechanism, the jet airflow is concentrated, and the induction effect 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] The jet fan is a special axial fan, which is mainly used in the longitudinal ventilation system of highways, railways and subways. It can also be used in the semi-transverse ventilation system or the sensitive parts of the transverse ventilation system, such as the entrance and exit of the tunnel. Play the role of inducing airflow or exhausting smoke. In the prior art, the angle of the ordinary jet fan cannot be adjusted, and sometimes there is a certain slope in some installation spaces, which cannot well play the role of inducing. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an induced jet fan, which can adjust the spray direction of the spray part through an angle adjustment mechanism, and the sprayed airflow is concentrated, and the induction effec...
