Technical Field
[0001] The utility model relates to the technical field of exhaust pipes for clean rooms, in particular to an exhaust pipe for a medical clean room with a purification structure. Background Art
[0002] A clean room refers to a well-enclosed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise are controlled as needed. To achieve the clean level in a clean room, comprehensive measures must be taken, including process layout, building plan, building structure, building decoration, personnel and material purification, air cleanliness measures, maintenance management, etc. Among them, air cleanliness measures are the fundamental guarantee for achieving the clean level.
[0003] In the medical industry, clean rooms are relatively widely used. For example, a clean operating room used for surgery is one of them. However, for ventilation, the gas in the room is usually discharged through an exhaust duct. Since the patient's air during surgery may also carry germs, when the gas is discharged directly, there may be a risk of spreading the disease. Therefore, there is an urgent need for an exhaust duct with a purification structure for a medical clean room to overcome the above defects. Utility Model Content
[0004] The purpose of the utility model is to provide an exhaust duct for a medical clean room with a purification structure, which has the advantage of good purification effect and solves the problems raised in the above-mentioned background technology.

[0006] Furthermore, the filter plate is fixedly mounted on the right side of the inner cavity of the sealed shell, and the output shaft of the first motor penetrates into the inner cavity of the purification box and is fixedly connected to the back side of the stirring frame.
[0007] Furthermore, the positioning seats are fixedly mounted on both sides of the inner cavity of the containing box, and the positioning rods slide in the inner cavity of the positioning seats.
[0008] Furthermore, the top of the positioning rod is fixedly connected to the bottom of the blocking plate, and the spring is sleeved on the surface of the positioning rod.
[0009] Furthermore, the conduit is arranged in the inner cavity of the purification box, and the top of the conduit is communicated with the bottom of the containing box.
[0010] Furthermore, the blocking disk is movably connected to the right side of the catheter through a positioning pin, and the drain valve is connected to the back side of the purification box.
[0011] Furthermore, the top of the containing box is connected to the right side of the sealed shell through an air duct, and the exhaust pipe is connected to the top of the purification box.
[0012] In summary, due to the adoption of the above technology, the beneficial effects of the utility model are:
[0013] The utility model mainly stores disinfectant water by arranging a purification component. When air enters the inner cavity of the purification component, pathogens in the air are disinfected and disinfected under the action of the disinfectant water. The anti-backflow component is arranged to prevent the disinfectant water from flowing back to the inner cavity of the suction component. The suction component is arranged to facilitate the transfer of air in the clean room. When in use, the fan and the first motor are turned on. Under the action of the fan, air enters the inner cavity of the containing box through the air guide pipe. Then, under the action of the airflow, the blocking plate drives the positioning rod to move downward, and the air is introduced into the inner cavity of the purification box through the conduit. At this time, the blocking plate is opened under the action of air pressure, and air enters the inner cavity of the purification box. Because the first motor drives the stirring frame to rotate, the disinfectant water is fully in contact with the air, thereby disinfecting the pathogens in the air, and finally the air is discharged through the exhaust pipe. The utility model has the advantage of good purification effect, and solves the problem that the patient's air may also carry pathogens during surgery, and when the gas is directly discharged through the exhaust pipe, there may be a risk of spreading diseases.
