Safety electric fan with high air outlet volumes

Abstract

The invention discloses a safety electric fan with high air outlet volumes. The safety electric fan comprises an air inlet assembly, an air outlet surface cover and electric cooling sheets. The air outlet surface cover is provided with air inlet holes, an air guide channel and air outlet slots; the air inlet holes are formed in the center of the back surface of the air outlet surface cover, and the air outlet slots are formed in the front surface of the air outlet surface cover; the air inlet assembly comprises a shell, a suction fan and an air channel, and the suction fan and the air channel are respectively arranged in the shell; a mesh plate which is used as an air inlet of the air channel is arranged at one end of the shell, and an air outlet of the air channel is formed in the other end of the shell; the air outlet of the air channel is communicated with the air inlet holes of the air outlet surface cover; mounting portions are arranged at the air inlet holes of the air outlet surface cover, and the end, where the air outlet of the air channel is formed, of the shell is fixed into the mounting portions; the electric cooling sheets are arranged in the air channel and are adjacent to the mesh plate; the suction fan is a turbine fan with turbine blades. The safety electric fan has the advantages of low noise, high air outlet volumes and refrigerating ability.

Description

technical field [0001] The invention belongs to the technical field of electric fan structure design, and in particular relates to a safe electric fan with a large air output. Background technique [0002] The current commercially available bladeless safety fan includes a base and an annular air outlet mask arranged on the base, and the base is provided with a suction assembly mainly consisting of a turbo fan; the biggest advantage of this fan is that it eliminates the traditional electric The fan blades used by the fan are extremely safe for both adults and children. However, this kind of fan also has the following disadvantages: in order to avoid bulkiness and bloat, the base with a smaller diameter is used, so the size of the turbo fan is limited. Hundreds to thousands of revolutions per second, resulting in a lot of noise, which is difficult to eradicate; in addition, because the diameter of the turbo fan is too small, although its speed is high, the air volume is still...

Problems solved by technology

However, this kind of fan also has the following disadvantages: in order to avoid bulkiness, a smaller diameter base is used, so the size of the turbo fan is limited. In order to ensure sufficient air output, the speed of the turbo fan is higher, generally reaching every Hundreds to thousands of revolutions per second, resulting in a lot of noise, which is difficult to eradicate; in addition, because the diameter of the turbo fan is too small, although its speed is high, the air output is still not comparable to that of traditional fans, and the blowing effect is not good.
