    Abstract: A blower is provided that may include a fan that creates airflow; a lower body forming a lower space therein in which the fan may be disposed, and having at least one suction hole through which air passes; a first upper body positioned above the lower body, and forming a first inner space that communicates with the lower space of the lower body; a second upper body positioned above the lower body, and forming a second inner space that communicates with the lower space of the lower body, the second upper body being spaced apart from the first upper body; and a space formed between the first upper body and the second upper body, and opened in a frontward-rearward direction. The first upper body may include a first slit formed through the first upper body such that air in the first inner space may be discharged into the space, and the second upper body may include a second slit formed through the second upper body such that air in the second inner space may be discharged into the space.

    Abstract: First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.

    Abstract: A mask apparatus includes a mask body, a seal disposed at a rear surface of the mask body, a fan module disposed at a front surface of the mask body, and a mask body cover that covers the fan module and is coupled to the front surface of the mask body. The mask body includes an air duct configured to guide external air from the fan module to a breathing space inside the seal, and an air exhaust hole configured to discharge air exhaled into the breathing space to an outside of the mask body. An area of a duct outlet of the air duct is greater than an area of a duct inlet of the air duct.
