Problems solved by technology

[0002] At present, in the home appliance market at home and abroad, when ordinary household electric fans are working, the air supply from the air outlet is almost concentrated and the wind speed is very high, which will bring inconvenience to the actual use of users. The human body is exposed to concentrated high-speed air for a long time. Under wind pressure, it is easy to make people uncomfortable and even cause harm to human health

Abstract

The invention discloses a wide-angle air-supply fan, comprising a front net, a front shell, a motor, a rear shell and a rear net, wherein the front net is connected with the front shell; the rear shell is detachably connected with the front shell; the rear net is detachably connected with the rear shell; the rear shell is provided with a front opening and a rear opening; and air-supply holes are arranged in the circumferential direction of the rear shell. The wide-angle air-supply fan is characterized in that air blocking plates are arranged in the circumferential direction of the rear shell. Due to the adoption of the structure, the horizontal air-supply distance is larger and the air-dispersing effect is stronger. The wide-angle air-supply fan has the advantages of excellent effect, simple and reliable structure and no increase in the cost, and is suitable for large-batch popularization.

Description

Technical field [0001] The invention relates to an electric fan. Background technique [0002] At present, in the home appliance market at home and abroad, when ordinary household electric fans are working, the air supply at the outlet end is almost concentrated and the wind speed is very high, which will bring inconvenience to the actual use of users, and the human body is exposed to concentrated high-speed Under wind pressure, it is also easy to make people uncomfortable and even harm human health. There are fans on the market that control the direction of the wind by adding a gathering and dispersing wind guide wheel and installing it on the front net, but this kind of gathering and dispersing wind guide wheel has no obvious effect on guiding the wind, and the wind angle is too small, which is difficult for users to feel To achieve the real effect of dispersing the wind, and it has many parts, complex structure and high cost, which is not conducive to mass promotion.
