Problems solved by technology

[0005] Because the face shapes of people in different regions are different, for example, the facial contours of European and American people are wider and deeper than those of Asians, so it is usually difficult for manufacturers of respirators in Asia to obtain the fit test results of respirators with European faces and data
However, it is time-consuming and labor-intensive to send to testing laboratories in Europe and the United States for testing

Embodiment Construction

[0039] figure 1 A schematic diagram showing a respiratory mask measuring device according to an embodiment of the present invention. Please refer to figure 1 , the respiratory mask measurement device 100 of this embodiment includes a respiratory simulator 110 , a leak detector 120 and a standard human head 130 . The standard human head 130 wears a breathing mask 200 to be tested. The breathing simulator 110 provides a simulated human breathing gas to a standard human head 130 . The leak detector 120 is used to detect the tightness of the breathing mask 200 . In addition, the breathing simulator 110 includes an eccentric crank circle 112 and a cylinder 114 . The eccentric crank circle 112 drives the stroke of the cylinder 114 , so that the cylinder 114 generates the simulated human breathing gas to the standard human head 130 accordingly.

Abstract

The invention provides a measuring device for a breathing mask and a measuring method thereof. The measuring device for the breathing mask comprises a standard human head, a breathing simulator and a leakage detector. A to-be-detected breathing mask is worn onto the standard human head. The breathing simulator provides simulated respiratory air for a human body to the standard human head. The leakage detector is used for detecting the sealing capacity of the breathing mask. The breathing simulator comprises an eccentric crankpin circle and a cylinder. The eccentric crankpin circle drives the stroke of the cylinder and the cylinder therefore generates simulated respiratory air for a human body and transmits the simulated respiratory air to the standard human head.

Description

technical field [0001] The invention relates to a measuring device and a measuring method thereof, in particular to a measuring device and a measuring method of a breathing mask. Background technique [0002] Respirator is a protective equipment provided for individuals to wear to avoid being harmed by hazardous factors in the air, and it is also the last hurdle to avoid harmful substances from causing harm to the human body. [0003] A qualified respirator must be able to effectively reduce the chance of pollutants being inhaled by the wearer. Generally speaking, when wearing a respiratory protective device, air pollutants can enter the protective device through three main channels, including flowing through the filter material, leakage of the surface body and the leakage of the exhalation valve. [0004] The common disposable mask is the simplest respiratory protective equipment. Disposable face masks are widely used because they are lightweight, reasonably priced, and e...
