Abstract

The utility model discloses a bladeless tower fan which comprises a base and a shell rotatably mounted on the base, wherein a fan assembly and a shaking head assembly are mounted at the bottom of the shell, a top cover is mounted at the top of the shell, an air outlet is formed in the outer side of the top cover, the section width of the top cover is gradually increased from top to bottom, blowing air of the fan assembly is sent into the top cover from bottom to top, and the blowing air is guided to the air outlet along the inner wall of the top cover and sent out due to the fact that the distance in the top cover is gradually reduced, and the air outlet quantity of the fan is greatly increased.

Description

Bladeless tower fan

Technical Field

The utility model relates to an electric appliance, in particular to a fan.

Background

The bladeless fan in the prior art rotates through the wind wheel to generate negative pressure, conveys the air quantity to the air cavity and blows out the air quantity through the air outlet, but the air quantity is limited by the inner wall of the air cavity when entering the air cavity, so that the air quantity is small, the poor air outlet effect, the stable integral air quantity and other adverse conditions are caused, and the use performance of the bladeless fan is reduced.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a bladeless tower fan.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

the utility model provides a bladeless tower fan, includes the base and rotates and installs shell on the base, the fan subassembly is installed and the subassembly of shaking the head to the bottom of shell, the top cap is installed at the top of shell, the outside of top cap is equipped with the air outlet, the cross-sectional width of top cap from top to bottom increases gradually.

The top cover is provided with a protrusion at one side opposite to the air outlet, and a guide arc surface is arranged at the bottom of the protrusion.

The outer side of the top cover is provided with an inwards concave lifting handle corresponding to the position of the bulge.

The top cover is integrally formed.

And an air inlet is formed in the outer side of the shell in a surrounding manner at a position corresponding to the fan assembly.

The utility model has the beneficial effects that: according to the utility model, the top cover is arranged at the top of the shell, the air outlet is formed in the outer side of the top cover, the section width of the top cover is gradually increased from top to bottom, the air blown by the fan assembly is sent into the top cover from bottom to top, and the air blown by the fan assembly is guided to the air outlet along the inner wall of the top cover and sent out due to the gradual reduction of the interval in the top cover, so that the air output of the fan is greatly increased.

Drawings

The utility model is further illustrated with reference to the following figures and examples.

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic cross-sectional view of the present invention.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description.
