Simulator capable of simulating breathing of human body

The invention provides a simulator capable of simulating breathing of a human body. The simulator comprises a simulated lung cavity (1), a controller (2), a power switch (3), an antenna (4) and an electric breathing pump (5), the simulated lung cavity (1) is made by using silica gel soft materials, the electric breathing pump (5) is connected with an air breathing pipeline, an outlet end of the air breathing pipeline extends out of the ground, when the power switch (3) is switched on, the simulator can start to work only by burying the simulator under the ground, and parameters of the simulator can be adjusted in real time by using the wireless radio frequency antenna (4) through the controller (2). The controller (2) controls exhaling and inhaling of the electric breathing pump (5) to enable the simulated lung cavity (1) to expand and contract to realize simulation effect of breathing of the human body. By adopting the technical features, compared with the prior art, the simulator capable of simulating breathing of the human body can simulate breathing of the human body more truly and is more convenient to adjust the parameters.
