Description

Technical Field

[0001] The utility model application relates to the technical field of dynamic poisoning cabinets, in particular to a dynamic poisoning cabinet with a ventilation device. Background Art

[0002] The poison control cabinet is an essential device for inhalation toxicology experiments. The dynamic poison control cabinet is equipped with a gas distribution system for inputting fresh air and replenishing the test substances during the poison control experiment. It is suitable for longer-term poison control and is used in various fields such as scientific research, agriculture, health, and education.

[0003] When a dynamic poison control cabinet is in use, a ventilation system is set up to facilitate the input of fresh air into the cabinet, so that fresh air can enter from the outside and the internal air can be discharged. When the air is discharged, it needs to be purified. However, when a traditional dynamic poison control cabinet is in use, the internal ventilation device cannot better control the air in and out, which makes it easy for the dynamic poison control cabinet to be pressurized due to poor internal ventilation when in use, and even affects the experimental results. Summary of the invention

[0007] A sealing plate is fixed inside the air outlet box, and a disinfection component is arranged inside the air outlet box between the sealing plate and the main body of the dynamic poison control cabinet. An exhaust pipe is fixed through the side of the sealing plate away from the main body of the dynamic poison control cabinet, and a second one-way air valve is arranged on the exhaust pipe. One end of the exhaust pipe away from the main body of the dynamic poison control cabinet passes through to the outside of the air outlet box.

[0008] Furthermore, the disinfection component includes a polyester fiber filter plate, a HEPA filter plate, an activated carbon filter plate and an ultraviolet disinfection lamp. The polyester fiber filter plate, the HEPA filter plate and the activated carbon filter plate are sequentially arranged inside the air intake box between the main body of the dynamic poisoning cabinet and the sealing plate, and a number of ultraviolet disinfection lamps are equidistantly arranged inside the air intake box between the activated carbon filter plate and the sealing plate.

[0009] Furthermore, guide plates are symmetrically fixed to the inner bottom surface of the air intake box below the fan, and both guide plates are arranged to be inclined toward the top of the air intake pipe.

[0010] Furthermore, an air inlet is provided in a side wall of the air inlet box outside the fan, and a dust filter is fixed inside the air inlet.

[0011] Furthermore, the sealing plate is arranged to be inclined toward the exhaust pipe, and the width between the sealing plate and the activated carbon filter plate is greater than the width of the ultraviolet disinfection lamp.

[0012] Furthermore, an air outlet hole cooperating with the exhaust pipe is provided inside the air outlet box at the side of the exhaust pipe, and a dustproof filter is fixed inside the air outlet hole.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, the one-way air valve at the inlet and outlet is controlled to ensure that fresh air can enter the main body of the dynamic poison control cabinet through the air inlet box during the experiment, and the exhausted air can be filtered through the polyester fiber filter plate, the HEPA filter plate and the activated carbon filter plate before being discharged through the exhaust pipe. While ensuring the experimental effect, it also avoids the internal air being discharged during the experiment to affect the external air environment, solving the problem of inconvenient air intake and exhaust during use of the existing dynamic poison control cabinet with a ventilation device.
