DETAILED DESCRIPTION

[0020] like Figure 1 As shown, a ventilation device for a mold test box includes a base 1, a tank body 2, the tank body 2 is fixedly connected to the upper end of the base 1, and a negative pressure component 3 slidably arranged in the tank body 2, the negative pressure component 3 is used to change the pressure in the tank body 2; it also includes a ventilation component 4 arranged on the left side of the tank body 2, the ventilation component 4 is used to sterilize and dehumidify the exhaust gas.

[0021] like Figure 2 As shown, the negative pressure component 3 includes a slider 5, a sealing plate 6, a liquid storage bin 7, a liquid inlet pipe 8 and a liquid return pipe 9. A slide groove is provided inside the tank body 2, and the slider 5 is slidably arranged inside the slide groove. The sealing plate 6 is fixed between the sliders 5, the liquid storage bin 7 is fixed to the right side outside the tank body 2, the liquid inlet pipe 8 is arranged between the liquid storage bin 7 and the tank body 2, the liquid return pipe 9 is arranged between the liquid storage bin 7 and the bottom of the tank body 2, a water pump 10 is provided in the liquid storage bin 7, and a liquid outlet 11 is provided on the right side of the liquid storage bin 7 to prevent gas from remaining in the tank body 2.

[0022] like Figure 2-3 -4, the ventilation assembly 4 includes a processing chamber 12, a ventilation pipe 13, a filter plate 14 and a filter plate 2 15. The processing chamber 12 is fixedly connected to the left side outside the tank body 2, the ventilation pipe 13 is arranged between the tank body 2 and the processing chamber 12, the ventilation pipe 13 is inserted at the bottom of the processing chamber 12, the filter plate 14 is fixedly connected to the upper part of the processing chamber 12, the filter plate 2 15 is fixedly connected to the upper end of the processing chamber 12, and the filter plate 14 and the filter plate 2 15 form a closed drying chamber 16 to sterilize the exhaust gas to prevent bacteria in the gas from polluting the environment.
