Description

Technical Field

[0001] The invention relates to the technical field of air purification, and in particular to a mobile biomedical isolation cabin. Background Art

[0002] The fresh air system is a new type of ventilation and exhaust equipment, which is an open circulation system that allows people to breathe fresh, clean, and high-quality air indoors. The fresh air system is composed of a fan, air inlet, air outlet, and various pipes and joints. The fan installed in the ceiling is connected to a series of air outlets through pipes. When the fan is started, the polluted air in the room is discharged to the outside through the air outlet and the fan, forming a negative pressure in the room. The fresh air outside enters the room through the air inlet installed above the window frame (between the window frame and the wall), so that the people indoors can breathe high-quality fresh air.

[0003] Purification is an important part of the fresh air system. The fresh air system usually has a purification device in the air inlet duct to remove some dust and large air particles in the air. A better purification device can even remove allergens and microorganisms (such as bacteria and bacteria) that affect human health. Although the purification device's filtering function is becoming more and more perfect, it cannot kill viruses. For example, the new coronavirus pneumonia needs to be inactivated at 56 degrees for 30 consecutive minutes. However, the fresh air systems on the market are mainly based on physical filtration and do not have the function of inactivating viruses.

[0004] The outbreak of the COVID-19 pandemic has led to people’s demand for fresh air systems with virus inactivation functions. The use scenarios of fresh air systems with virus inactivation functions have also been greatly expanded: homes, hospitals, shopping malls, cinemas, museums, libraries, KTVs, schools, factories, office buildings, hotels, ambulances, buses, high-speed railways, subways, cruise ships, airplanes, ships, etc. all have urgent needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in view of the technical problems existing in the prior art, the present invention provides a mobile biomedical isolation cabin with good purification effect, high purification efficiency and the ability to completely kill various microorganisms.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0010] A partition is arranged between each adjacent discharge plate, one end of the partition is arranged on the cathode, and a certain gap exists between the other end and the anode.

[0030] In a preferred embodiment, the air shower unit 2 includes a plurality of high-pressure nozzles 201 located above the air shower room 101, and each high-pressure nozzle 201 is connected to an air pump. External air is sucked in by the air pump, filtered, and then enters the nozzle 201, sprayed on the human body to remove dust or foreign matter, and then filtered again and discharged to the outside of the air shower room 101. Of course, according to laboratory standards, the air entering the air shower room 101 can also be purified before being sprayed into the air shower room 101, and the air in the air shower room 101 can be purified before being discharged to the outside of the air shower room 101.
