the rain system controls the water pumping amount of the water pump 903 through the first control switch 10, the connecting disc 802 connects the fixed pipe 801 with the water outlet tray 803, so that water in the first water tank 9 can flow out of the water tray 803, so that the water outlet amount of the water outlet tray 803 can be controlled by controlling the water pumping amount of the water pump 903, then the driving motor 13 is started to enable the second gear 1301 to rotate towards one direction, the water limiting tray 11 rotates around the rotating rod through the matching of the second gear 1301 and the rack 1101, the position of the water outlet 12 of the water limiting tray 11 can deviate from the position of the water outlet 12 of the water outlet tray 803 in the rotating process of the water limiting tray 11, so that the solid part of the water limiting tray 11 can shield the water outlet 12 of the water outlet tray 803, the aperture of the water outlet 12 of the water outlet tray 803 can be slowly reduced, then small raindrops are formed, and then the driving motor 13 enables the second gear 1301 to rotate towards the other direction, the aperture of the water outlet 12 of the water outlet tray 803 is gradually changed to be large, and then large raindrops are formed, so that the rainfall in the closed room really forms small rain, medium rain, heavy rain and heavy rain; the humidity control system controls the evaporation device 2202 to work through the second control switch 20, water in the second water tank 21 enters the atomizing groove 2203 through the hose 2101, then the water entering condition in the atomizing groove 2203 is sensed through the sensing head, when water exists in the sensing lamp atomizing groove 2203, the water in the atomizing groove 2203 is atomized, the atomized steam is discharged out of the humidifier 22 through the first fog outlet 2204 and the second fog outlet 2205, then the fog enters the air outlet pipeline 2401 of the guiding device 24 to be pinched, and the fog is conveyed into the closed chamber through the matching of the auxiliary fan 2402 and the through hole, namely the auxiliary fan 2402 forms an upward wind force when operating, so that the fog is filled in the whole closed chamber 1, the humidity in the closed chamber can be controlled through controlling the speed and the duration of the fog generated by the humidifier 22, so as to keep the humidity in the closed chamber 1 at 0-95%, in a specific experiment, the first temperature controller 307 is controlled to control the temperature of the human body part 301 of the dummy to be 36.5 ℃, then the second temperature controller 5 controls the temperature in the closed room 1 to be 10 ℃, and then four groups of experiments are carried out under the condition of the same temperature, wherein in the first group of experiments, the rainfall is set to be light rain through the rain system, the wind speed adjusting system does not start the wind speed to be 0 m/s, and the humidity control system does not start the humidity to be 0; in the second group of experiments, the rainfall is set as medium rain through a rain system, the wind speed is set as 2 m/s through a wind speed adjusting system, and the humidity is 25% through a humidity control system; in the third group of experiments, the rainfall is set as heavy rain by a rain system, the wind speed is set as 4 m/s by a wind speed adjusting system, and the humidity is 45% by a humidity control system; in the fourth group of experiments, the rainfall is set as rainstorm through a rain system, the wind speed is set as 6 m/s through a wind speed adjusting system, and the humidity is 65% through a humidity control system; under the four different rainfall, wind speed and humidity conditions, the first temperature controller 307 collects the internal temperature of the clothes and transmits the internal temperature to a microcomputer controller to obtain the heat dissipation rate of the ready-made clothes at each environmental temperature, the power consumption of the equipment is collected to obtain the heat preservation average power of the ready-made clothes to obtain four groups of data, the first group of data is 0.25 ℃/min, the heat preservation average power of the ready-made clothes is 15W, the second group of data is 0.40 ℃/min, the heat preservation average power of the ready-made clothes is 20W, the third group of data is 0.65 ℃/min, the heat preservation average power of the ready-made clothes is 25W, the fourth group of data is 0.80 ℃/min, the heat preservation average power of the ready-made clothes is 35W, the better the heat preservation effect of the ready-made clothes by combining the four groups of data is, the corresponding cooling rate is smaller, and the average power is also smaller; on the contrary, the worse the warming effect, the larger the corresponding cooling rate, the larger the average power, and the lower the ambient temperature, under the same condition, the larger the corresponding heat dissipation rate, and the larger the average power.
