Description

Technical Field

[0001] The present invention relates to the technical field of shelters, and in particular to a working shelter capable of purifying air. Background Art

[0002] Traditional work cabins only have normal in-cabin working functions, including air conditioning and heating systems, natural air pressure, etc., so people in the cabin can breathe normally. However, when the work cabin is in an air environment contaminated by bacteria and viruses, polluted gases can easily enter the cabin, posing an infection threat to people in the cabin.

[0003] A Chinese patent (publication number: CN110005242A) discloses an accident-resistant shelter that is fire-resistant, impact-resistant, and gunfire-resistant. The overall skeleton of the patent uses a main frame, an inner frame, and an outer frame to form a high-strength overall frame, which not only ensures the high strength and high rigidity of the overall skeleton under impact conditions, but also reduces the metal area directly connected to the inside and outside of the shelter, which is beneficial to reducing heat transfer between the inside and outside of the cabin. However, during construction, it was found that the sealing performance inside the cabin could not be effectively guaranteed, and it could not be used in an air environment contaminated by bacteria and viruses.
