The switch baffle 204 forms a rotating structure with the delivery pipe 203 through the switch knob 205, and the delivery pipe 203 forms a connecting structure with the liquid tank pipe 202 through the water pump 201. The smoke spraying body 207 forms a rotating structure with the rotating shaft body 206 through the angle control knob 208, and the smoke spraying body 207 forms a connecting structure with the delivery pipe 203 through the rotating shaft body 206. The water pump 201 is started, and the water pump 201 extracts the liquid in the liquid tank body 301 through the liquid tank pipe 202, and transports it to the smoke spraying body 207 through the delivery pipe 203. The smoke spraying body 207 sprays the test object with smoke. The switch knob 205 is turned to control the position of the switch baffle 204 to adjust the spraying speed of the liquid in real time. The angle control knob 208 is turned to make the smoke spraying body 207 rotate around the rotating shaft body 206, and the spraying angle of the smoke spraying body 207 can be adjusted. This makes it convenient to spray smoke into the test box without opening the box door, ensuring that the temperature inside the test box meets the standard and the accuracy of the test.
