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.

The invention discloses a low-noise safety electric fan. The low-noise safety electric fan comprises an air inlet component, an air outlet cover and electric cooling sheets; the air outlet cover is provided with an air inlet hole, air guide passages and air outlet slots, the air inlet hole is formed in the center of the back surface of the air outlet cover, and the air outlet slots are formed in the front surface of the air outlet cover; the air inlet component comprises a shell, a suction fan and an air passage, and the suction fan and the air passage are arranged in the shell; one end of the shell is provided with a mesh plate serving as an air inlet of the air passage, and the other end of the shell is provided with an air outlet of the air passage; the air outlet of the air passage is communicated with the air inlet hole of the air outlet cover; a mounting portion is arranged at the air inlet hole of the air outlet covers, and one end, with the air outlet of the air passage, of the shell is fixed in the mounting portion; the electric cooling sheets are arranged in the air passage and adjacent to the mesh plate; the suction fan is a turbine fan with turbine blades. The low-noise safety electric fan has advantages of low noise, high air output and realization of refrigeration.
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 low noise. 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 not comp...
