Front safety net for fans with good compatibility

Abstract

Disclosed is a functional front safety net of an electric fan, having excellent compatibility, the front safety net increasing the linearity of wind so as to enable the cooling efficiency of an electric fan to improve when the front safety net is coupled to a rear safety net of a conventionally used electric fan, and, specifically, being fixedly coupled quickly and easily and usable through elongated holes and fastening pieces, which are formed at a coupling part, without being influenced by the diameter of the edge of the rear safety net of the conventionally used electric fan.

Description

technical field [0001] The present invention relates to a front safety net of a fan, and more particularly, to a front safety net connected with a rear safety net arranged on the rear surface of a fan blade, comprising: an annular guide having a front opening and a rear opening, and formed with a predetermined width to improve the efficiency of the fan by ensuring the straightness of wind generated during the rotation of the blade; a plurality of protective ribs formed on the front surface of the guide to protect the blade; combined part, formed to have a predetermined width so as to be bent vertically outward from the rear edge of the guide and closely contact the edge of the rear safety net to support the rear safety net, and formed with a long hole through which Through the fastener, the fastener is used to detachably combine with the fastening clip tightly attached to the edge of the rear safety net, the wind generated during the rotation of the blade passes through the gu...

Problems solved by technology

[0003] The problem with this type of fan is that since the rotating blades rotate according to the drive of the motor to introduce the wind from the rear side to the front side, thereby providing cool wind to the user in summer, however, the wind cannot spread widely to a distance

[0004] Air conditioners are used to overcome the disadvantages of such fans, but they are expensive, and there is a problem of increasing costs due to low energy efficiency, therefore, the air conditioner and the fan are operated at the same time to more actively cause air circulation in the room, thereby increasing the cooling efficiency of the air conditioner and reduce power consumption

[0005] However, since the wind from the fan spreads over a wide range, the air circulation ability cannot be spread far due to the wind, in order to overcome this problem, an air circulator with excellent wind straightness has recently been used instead of the fan, however, the air circulator needs to be purchased separately, resulting in the purchase The problem of further cost increases
