Description
Technical Field
The utility model relates to an exhaust port, in particular to an exhaust port of a high-efficiency energy-saving fan.
Background
Most of the exhaust openings in the prior art are in one-to-one form, and are structurally in a plane structure, wherein turbulence phenomenon is easily caused in the exhaust benefits, and wind resistance and energy consumption are caused.
Disclosure of Invention
The utility model provides an exhaust port of a high-efficiency energy-saving fan, which is used for overcoming the defect that the exhaust ports in the prior art are all of plane structures and are easy to cause turbulence.
In order to solve the technical problems, the utility model provides the following technical scheme:
the utility model discloses an exhaust port of a high-efficiency energy-saving fan, which comprises a fan, wherein an exhaust port flange is arranged on the fan, an arc-shaped guide cover is arranged above the exhaust port flange, an exhaust cover matched with the guide cover is arranged on the guide cover, and an exhaust port is formed in the exhaust cover.
Further, a sealing strip for leakage prevention and sealing is arranged between the air guide sleeve and the exhaust sleeve.
Further, the bottom of the exhaust hood is provided with an arc-shaped cover plate for being attached to the air guide hood.
Further, a locating pin fixed and locked with the exhaust hood is arranged on the arc-shaped cover plate.
Further, the sealing strips are respectively connected with the air draft cover through colloid.
Further, the arc-shaped cover plate is made of plastic materials, metal materials or composite materials.
Further, the exhaust openings are integrally formed or are formed by a plurality of combinations.
The beneficial effects achieved by the utility model are as follows: the circular arc design structure of the air suction port increases the machine body or space, effectively reduces the wind resistance and increases the convection effect, so that the loss of wind resistance is avoided in the process of transmitting the air quantity during the air suction; the air suction port has extremely strong compression resistance due to the arc structure, and the object structure is not easy to collapse and deform due to vacuum factors when the vacuum negative pressure value is higher.
