Description

Perforator for mask
[ technical field ] A method for producing a semiconductor device
The invention relates to a respirator perforator, in particular to a respirator perforator which can be used by assembling an air valve on a common respirator by perforating a hole on the respirator.
[ background of the invention ]
In a polluted atmosphere environment, a mask is used as a means for protecting a respiratory tract, and recently, the usage amount of the mask is increased greatly due to yellow sand, influenza, a mutant virus and the like.
The mask widely used generally is made of materials such as cotton, non-woven fabrics and paper, has a filtering effect, and can isolate inhalable particles, viruses or cold air in the air to protect the respiratory tract.
However, the mask is tightly attached to the face after wearing the mask, so that the breathing is not smooth, and the mask is difficult to wear for a long time due to moisture and discomfort generated during expiration.
In view of these problems, a mask having an air valve attached to one end of the mask is used, and patent document 1 exemplifies a mask having an air valve.
As described above, the mask equipped with the air valve has an advantage in that uncomfortable air inside the mask can be rapidly discharged, so that breathing becomes more comfortable.
However, the mask equipped with the air valve cannot be worn for a long time, and the mask increases the economic burden as compared with the conventional mask, and is still unacceptable for people who wear the mask for a long time.

The inner part of the shell (10) is communicated, the rotary knife (20) is inserted into the inner diameter tightly attached to the shell (10), the annular convex part (21) of the rotary knife (20) limits the rotary knife (20) from being further inserted into the shell (10), and the lower end of the rotary knife (20) is positioned the same as the lower end of the shell (10).
A plurality of blade receiving grooves (23) are formed outside the rotary knife (20) so that the blades (40) are received.
The blade (40) is used by cutting off a widely used so-called cutting blade (a blade used by pushing a handle to pull out the blade in a blade holder by a required length), so that the blade mounting groove (23) is formed in a shape corresponding to the shape of the blade (40), a part of the blade mounting groove (23) is arranged slightly downward, the lower end of the blade (40) protrudes downward of the rotary blade (20) when the blade (40) is assembled, and a part of the blade mounting groove (23) is arranged slightly upward, and the blade (40) is prevented from protruding downward of the rotary blade (20).
Therefore, when the rotary knife (20) is used, the blade (40) is clamped into the blade placing groove (23) arranged towards the lower side for use, and when the rotary knife is not used, the blade is clamped into the groove arranged towards the upper side for storage.
The mask is cut and perforated by the blade (40) protruding to the lower side of the rotary knife (20), but the thickness of the mask is different, so in view of these problems, as shown in fig. 4, the blade is formed according to the height of the blade mounting groove (23) formed on the outer surface of the rotary knife (20), and the height (d) of the blade (40) protruding to the lower side is changed.
