Problems solved by technology

[0006] However, according to the prior art, there is the following inconvenience: in order to fix the air supply fan to the mask, the air supply fan needs to be inserted between the front frame and the back frame, and then the front frame and the back frame are combined
[0007] In addition, in order to maintain the air supply fan, the front frame and the back frame must be separated to separate the air supply fan from the functional mask, so there is a problem that the assembly time of the functional mask becomes longer.
[0008] In addition, in the process of combining the blower fan to the front frame and the back frame, if the blower fan moves out of the installation position, there will be a problem that the front frame and the back frame cannot be properly combined.
[0009] In addition, when the air supply fan located between the front frame and the back frame is not properly fixed, the vibration generated in the air supply fan is transmitted to the functional mask through the front frame and the back frame, thereby appearing in the functional mask. Problems generating noise caused by vibration

Abstract

The invention relates to a mask device. The mask device according to an embodiment of the present invention may comprise: a mask body (10) comprising an air passage part (120) formed on the front side and a fan module mounting part (110) formed on the suction-side edge of the air passage part (120); a fan module (16) disposed on the fan module mounting part (110) and provided with a fan suction port (162) and a fan discharge port (163) so as to supply outside air to the air passage part (120); and a mask body cover (20) coupled to the front surface of the mask body (10) so as to cover the fan module (16) and the air passage part (120).

Description

technical field [0001] The present invention relates to mask devices. Background technique [0002] Generally speaking, a mask is a device that covers the user's nose and mouth in order to avoid the inhalation of germs, dust, etc., or the spread of droplets caused by viruses or bacteria. The mask is tightly attached to the user's face in order to cover the user's nose and mouth. The mask filters germs, dust, and the like contained in the air flowing into the user's nose and mouth, and allows the filtered air to flow into the user's mouth and nose. Air and germs, dust, etc. contained in the air pass through the body of the mask including the filter, and germs, dust, etc. are filtered by the body of the mask. [0003] But because the air flows into the user's nose and mouth after passing through the body of the mask, the air that the user spits out also flows out after passing through the body of the mask, thereby causing the problem that the user cannot breathe smoothly. R...
