Detailed Description
In the embodiment, as shown in fig. 1 to 5, a jet fan with adjustable air inlet and outlet directions comprises a hollow cylindrical air duct 11, a motor 12 is fixed in the air duct 11, an impeller 13 is connected to a drive shaft of the motor 12, a spherical sleeve 2 is fixed at each end of the air duct 11, a rotatable air inlet and outlet duct 3 is connected to the spherical exterior of the spherical sleeve 2, and the air inlet and outlet duct 3 is fixed to the corresponding spherical sleeve 2 through an anchor ear 4.
Furthermore, the spherical sleeve 2 comprises a drum-shaped block 21 which is large in middle and small in two ends and is symmetrically arranged, a step through hole 22 which axially penetrates through the drum-shaped block 21 is formed, and a large end hole of the step through hole 22 is inserted and fixed at the end part of the air duct 11;
the air inlet and outlet barrel 3 comprises a hemispherical barrel 31 and a straight barrel 32 which are integrally formed, and a plurality of slots 33 which are uniformly distributed in the circumference are formed at one end of the hemispherical barrel 31 far away from the straight barrel 32; the spherical inner wall of the hemispherical cylinder 31 is pressed against the spherical outer wall of the drum block 21; the hoop 4 is sleeved on the outer wall of one end of the hemispherical cylinder 31 far away from the straight cylinder 32.
Furthermore, two circles of arc-shaped barrier strips 34 protruding outwards are formed on the outer wall of one end of the hemispherical cylinder 31 away from the straight cylinder 32;
the hoop 4 comprises two symmetrically arranged holding claws 41, the holding claws 41 comprise an integrally formed arc-shaped plate 411 and two clamping plates 412 arranged at two ends of the arc-shaped plate 411, and the clamping plates 412 on the same side of the two holding claws 41 are fixedly connected through bolts 42; the arc-shaped plate 411 is inserted between the two circles of arc-shaped barrier strips 34; the spherical center of the spherical sleeve 2 is within the range of the circle enclosed by the two arc-shaped plates 411.
