Abstract
Description
[Technical Field]
[0001] The present invention relates to a blower fan, and more particularly to a structure that can prevent the intake port from being blocked by a cover structure provided on the blower fan. [Background technology]
[0002] Many conventional small air blowing fans have flat lids, which means that when the fan is attached to the stroller seat (attachment object 5) during use, the seat 5 tightly fits onto the stroller body 6, blocking the air intake vent 3 and reducing air blowing performance. Summary of the Invention [Problem to be solved by the invention]
[0003] The purpose of this invention is to provide a structure that prevents the air intake 3 from being blocked due to interference with the stroller body 6, even when the air blower fan is attached to the stroller seat 5, and ensures stable airflow. [Means for solving the problem]
[0004] This device comprises a fan body 1 equipped with a lid body 2, which is provided with a plurality of vents 3 and a detachable protrusion 4 in the center thereof. [Effects of the Invention]
[0005] According to this device, the protrusion 4 ensures a space between the vent 3 of the lid body 2 and the stroller body 6, making it difficult for the intake air to be obstructed and ensuring a stable airflow. Furthermore, the detachable protrusion 4 allows for flexible use according to the usage environment. [Brief explanation of the drawings]

[Figure 5] An explanatory diagram of a state in which an attachment object 6 is hung on an installation object 5 DETAILED DESCRIPTION OF THE INVENTION [Example]
[0007] The blower fan of the present invention comprises a fan body 1 and a cover body 2 as shown in FIG.
[0008] The lid body 2 is provided with a plurality of ventilation holes 3, and a protrusion 4 is detachably attached to the center.
[0009] The protrusion 4 is fixed by a screw or a claw engagement method, and can be easily removed by the user.
[0010] When the protrusion 4 is attached as shown in FIG. 2, a space is formed between the ventilation opening 3 of the lid main body 2 and the stroller main body 6 .
[0011] As shown in FIG. 5, even when the blower fan is attached to the stroller seat 5, a space is secured between the stroller body 6 and the fan, making it difficult for the vent 3 to be blocked and ensuring that the intake air is not obstructed. [Explanation of symbols]
