Problems solved by technology

[0009] However, this front safety net body is helical, which causes local eddy currents to be formed in front of the safety net body, which reduces the air supply distance and reduces the air supply efficiency. Although the straightness of the wind is improved, the unevenness of the spiral The wind makes the touch on the user's face different from the soft natural wind

Abstract

The present invention relates to a canister-type fan structure and, more specifically, to a canister-type fan structure having a housing, in which wings for generating wind are mounted, of a canister shape having a certain standard to improve a wind blowing efficiency. In addition, the canister-type fan structure has safety net bodies having an optimal shape and mounted to front and rear surfaces of the canister-type housing, so as to blow soft wind close to the natural wind. To this end, the canister-type fan structure of the present invention comprises: a canister-type housing which is provided with wings for generating the wind rotatably mounted thereon and has predetermined lengths in forward and backward directions from the mounting position of the wings; and a front safety net body which is mounted on the front surface of the canister-type housing and is provided with protecting ribs so that a plurality of wind holes form a certain pattern.

Description

technical field [0001] This application relates to a cylindrical fan structure. Specifically, the cylindrical fan structure is composed of a cylindrical shell and safety nets arranged at the front and rear ends of the cylindrical shell. The fan blades are installed inside the shell. The air holes (such as air holes) on the safety net body have a shape more suitable for ventilation. Background technique [0002] Generally speaking, a fan that can be used at home or in an office to produce air after being powered on is a household appliance that is commonly used in hot summer. [0003] This type of fan is driven by a motor to rotate the fan blades so that the air flows from the back to the front to generate cool wind for users to use in summer. At the same time, this type of fan can be used by multiple people in a large area. Due to the high-speed rotation of the fan blades, if the user's fingers and the like enter into contact with the fan blades, there is a danger of injury...
