[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides a technical solution: a safe intelligent ventilation device for laboratories, including a cabinet 1, an operating table 2 located in the middle of the cabinet 1, and a ventilation mechanism 3 movably mounted above the operating table 2 inside the cabinet 1. The ventilation mechanism 3 includes an adsorption box 301 and several fans 306. The bottom of the adsorption box 301 has first servo cylinders 302 vertically and symmetrically mounted at both ends. A rotatably connected air guide duct 303 is horizontally mounted at the bottom of the adsorption box 301. The bottom of the air guide duct 303 has several air intakes 304, and the top of the air guide duct 303 has an air vent 305. The fans 306 are located at the top of the cabinet 1. The fans 306 and the adsorption box... A first corrugated pipe 307 is provided between 301; a gear 309 is sleeved on one end of the outer wall of the air guide duct 303; a second servo electric cylinder 310 is horizontally provided at one end of the bottom of the outer wall of the adsorption box 301; a rack 311 that meshes with the gear 309 is horizontally provided at the output end of the second servo electric cylinder 310; an activated carbon filling frame 312 is inserted into one side of the outer wall of the adsorption box 301; the adsorption box 301 has an insertion cavity that matches the activated carbon filling frame 312; the top of the activated carbon filling frame 312 is open, and the bottom of the activated carbon filling frame 312 is hollow; the maximum pore size of the hollow structure is smaller than the particle size of the activated carbon adsorption particles.

[0023] In one embodiment, the end of the fan 306 away from the first corrugated pipe 307 is connected to the external ventilation duct through the second corrugated pipe 308. The fan 306 performs negative pressure suction on the adsorption box 301 through the first corrugated pipe 307, and the fan 306 delivers the negative pressure suction gas to the ventilation duct inside the laboratory through the second corrugated pipe 308. This can effectively transport the gas generated in the experiment on the operating table inside the laboratory to the ventilation duct of the laboratory for unified treatment.

[0024] In one embodiment, the bottom of the adsorption box 301 is provided with a movable cavity that matches the air guide 303. The bottom of the insertion cavity is connected to the top of the movable cavity, and the top of the insertion cavity is connected to the bottom of the first corrugated pipe 307. The movable cavity provides swing space for the air guide 303, ensuring that the air guide 303 can swing inside the bottom of the adsorption box 301, while ensuring that the gas treated by the air guide 303 completely enters the adsorption box 301 and does not leak gas during the swinging process.

[0025] The working principle of this utility model:

[0026] Refer to the instruction manual appendix Figures 1-4This utility model comprises an operating platform 2, a ventilation mechanism 3, an adsorption box 301, a first servo electric cylinder 302, an air duct 303, an air intake 304, an air duct 305, and a first corrugated pipe 307. The operating platform 2 provides operating space for chemical, biological, and physical experiments. When conducting experiments on the operating platform 2, the ventilation mechanism 3 is activated. The adsorption box 301 in the ventilation mechanism 3 provides adsorption material, which can effectively perform preliminary adsorption and purification treatment on the gases generated in the experiment, effectively reducing the pressure of subsequent ventilation and purification treatment. The air intake 304 at the bottom of the air duct 303 is used to draw in the gases generated in the experiment. The air vent 305 at the top of 303 is used to transport the gas inside the air duct 303 to the adsorption box 301. The first corrugated pipe 307 is used to provide telescopic connection and support between the adsorption box 301 and the fan 306. The telescopic movement of the first servo electric cylinder 302 can drive the adsorption box 301 to perform lifting and adjusting movements, which can effectively adjust the distance between the air vent 304 and the operating table 2. It can adjust the distance between the air vent 304 and the gas generated during the experiment, which is convenient for the gas generated during the experiment to be quickly and easily treated. It can effectively improve the rapid air suction and ventilation guidance treatment of toxic or irritating gases generated during the experiment.

[0027] When the ventilation mechanism 3 is working, the fan 306 is turned on. The fan 306 generates negative pressure and draws air into the adsorption box 301 through the first corrugated pipe 307. The adsorption box 301 draws air through the air intake 304 at the bottom of the air guide duct 303. The gas generated by the experiment at the top of the operating table 2 enters the air guide duct 303 through the air intake 304, and then enters the adsorption box 301 through the air guide 305 at the top of the air guide duct 303 for adsorption. After passing through the adsorption box 301, the gas is transported to the ventilation duct inside the laboratory for ventilation under the action of the fan 306 through the first corrugated pipe 307.

[0028] Gear 309 is supported at one end of air duct 303. The second servo cylinder is adjusted to extend and retract. The second servo cylinder drives rack 311 to perform horizontal reciprocating motion. Rack 311 and gear 309 mesh with each other, which can drive gear 309 to swing back and forth. Air duct 303 swings with gear 309, which can realize the swing adjustment of air intake 304 at the bottom of air duct 303. This allows air intake 304 to swing and adjust according to the gas source generated during the experiment, resulting in better air intake treatment effect.

[0029] The activated carbon filling frame 312 inserted into the inner side of the adsorption box 301 is used to hold the filled activated carbon adsorption particles. The insertion cavity provides insertion space for the activated carbon filling frame 312. The top of the activated carbon filling frame 312 is designed to be open, and the bottom of the activated carbon filling frame 312 is designed to be hollow. This ensures that the gas being drawn in enters the interior of the activated carbon filling frame 312 through the hollow structure at the bottom of the activated carbon filling frame 312 for adsorption treatment. After the gas has been adsorbed, it is discharged from the top opening of the activated carbon filling frame 312. The maximum pore size of the hollow structure is designed to be smaller than the particle size of the activated carbon adsorption particles, which can effectively prevent the activated carbon adsorption particles from leaking from the bottom of the activated carbon filling frame 312 and ensure the adsorption treatment effect of the gas.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
