  • the invention relates to an electric fan, in particular to a leafless fan with good air blowing effect. Background technique
  • the fans are in the form of a leafed fan that moves in a specified direction by cutting the drive air to form a wind.
  • This type of fan due to its relatively dangerous and noisy drawbacks, has been slowly abandoned by users.
  • the leaf fan uses the air to be injected to drive the air to form a wind.
  • the existing bladeless fans use a diffuse, Coanda surface, which also results in a significant diffusion of wind, and the effective range of wind blowing is small, air from Coanda When the surface is blown, there is a large friction loss and the wind is small.
  • the cavity formed between the casing and the impeller hood has an air flow passage, and the upper end of the cavity is sealed so that the airflow no longer flows therethrough, and the structure is relatively complicated because the connection parts of the various components are here. It is easy to form turbulent flow, and such a problem does not occur after the sealing member is provided, so that the airflow discharged from the air outlet is more stable, the air blowing effect is improved, and the noise is also reduced.
  • the flexible seal is located above the cavity, and different seals can be selected between the two components depending on the structure.
  • the wind ring comprises an outer ring and an inner ring, in the housing
  • An outer air ring is connected to the upper portion, and the flexible seal is located between the impeller hood and the outer air ring.
  • the outer air ring is connected to the outer casing, and the shape of the outer air ring is narrowed upward by the outer casing.
  • a sealing ring is arranged to seal the upward airflow, and no turbulent flow is formed in the cavity, and at the same time, due to the outer wind ring
  • the detachability with the outer casing makes it easier to change the adjustment when installing the seal. In the previous installation of the seal, the seal was required to be installed before the installation of the whole machine. When the seal was worn, the replacement was very inconvenient, and the components such as the impeller cover must be removed.
