Warm-body dummy for simulating dynamic release of exhaled droplets and simulation method thereof

Abstract

The invention discloses a warm-body dummy for simulating dynamic release of exhaled droplets and a simulation method thereof. The warm-body dummy comprises a dummy body, a heating part, a first action part, a second action part and a release device. The dummy body comprises a body part and a movable head part, and the head part is provided with an opening part capable of being opened and closed. The heating part is used for heating the dummy body to a preset temperature. The first action part drives the head part to move relative to the dummy body. The second action part drives the opening part to open and close. The release device outputs a particulate material to the outside of the dummy body when the mouth part is open. According to the warm-body dummy, the first action part enables the head part to move relative to the body part to achieve multi-angle actions of the head part. The second action part enables the mouth part to form opening and closing motion close to a real person. In the opening process of the mouth part, the particulate material is output to the outside of the dummy body. The dummy body is in the preset temperature range, the particulate material released by the mouth part is close to the droplet spreading process formed in the action process of a real person, and the test is reliable.

Description

technical field [0001] The invention belongs to the technical field of thermal mannequins, in particular to a thermal manikin for simulating the dynamic release of exhaled droplets and a simulation method thereof. Background technique [0002] The thermal manikin with the appearance characteristics of the human body is an instrument that can simulate the temperature distribution of the human body surface. It can replace the real person to do experiments, so as to systematically evaluate the physiological response of the human body in harsh environments and effectively prevent adverse environmental effects. Real people causing bodily harm. Biophysical experiments using thermal dummies have been widely used in clothing, construction, environment, aerospace, traffic safety and other fields. [0003] During the ravages of the novel coronavirus, it is very necessary to study the characteristics of human-to-human transmission. In related technologies, thermal mannequins are used...

AI Technical Summary

Problems solved by technology

To this end, the present invention proposes a thermal manikin that simulates the dynamic release of exhaled droplets. The thermal manikin can discharge particulate matter when the head performs different movements, providing a more reliable aerosol transmission process. data, which solves the problem of inaccurate test data in the thermal manikin in the prior art during the droplet transmission experiment
