PROBLEM TO BE SOLVED: To determine a leak point of exhalation, dust, and the like in a dust-proof implement such as a dust-proof mask under an actually worn condition when performing quality inspection thereof.SOLUTION: A human head type air flow testing device, which is used for performing quality inspection of a dust-proof implement worn for preventing dust from being produced from a human body in a clean space, includes a human head dummy capable of wearing the dust-proof implement and dust production auxiliary equipment. The dust production auxiliary equipment is provided with an air outlet and a breathing air intake in an area corresponding to a nose or a mouth of the human head dummy. The dust production auxiliary equipment includes a mist or dust generator that produces mist or dust artificially for sending out the mist or dust into the human head dummy and discharging it from the air outlet, and a pump for performing exhalation simulation operation of taking air from the breathing air intake into the human head dummy and discharging it from the breathing air intake. The surface of the human head dummy is subjected to a light absorption treatment for enhancing visualization of the mist or dust air flow leaking from the dust-proof implement. |
