The invention discloses an air disinfection and purification device installing at a public traffic vehicle escape window. The air disinfection and purification device comprises a disinfection and purification component, an inner circulation fan set, a fresh air exhaust fan set, an air guide component and a main control panel, the inner circulation fan set and the disinfection and purification component are positioned in the same air channel, the air guide component is arranged below the fresh air exhaust fan set and positioned in an air channel perpendicular to the disinfection and purification component, the disinfection and purification component, the inner circulation fan set, the fresh air exhaust fan set and the air guide component are electrically connected with the main control panel, and the main control panel is connected with an operation platform positioned at a driving position of a public traffic vehicle and a power supply. According to the air disinfection and purification device, in-vehicle disinfection, air change and introduction of fresh air are integrated, a driver can select suitable modes to improve in-vehicle air quality according to conditions such as weather and passenger density, inner space of the public traffic vehicle cannot be occupied, normal use of the escape window cannot be affected, and safety of the public traffic vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of air purification devices, in particular to an air disinfection and purification device installed at the escape windows of public transport vehicles. Background technique [0002] At present, whether it is a passenger car, a bus or a car on the market, a built-in HEPA filter is installed near the front of the car. This filter is mainly to control the air inhaled from the outside of the car. HEPA is called a high-efficiency filter. The service life of HEPA is about 3 months to half a year, but it largely depends on the quality of the outside air. For example, in Hainan, Shenzhen and other areas with good air quality, the life of HEPA can reach 8 months or even a year. However, in areas with serious air pollution such as Hebei and Shanxi, the lifespan of HEPA is only 2 to 3 months. However, for large and medium-sized passenger cars, especially public transport vehicles, due to the large number of people in ...

AI Technical Summary

Problems solved by technology

However, for large and medium-sized passenger cars, especially public transport vehicles, due to the large number of people in the car and the high density, only relying on HEPA to filter the air outside the car, the air quality in the car cannot meet the requirements, affecting the health of the passengers; When public transport vehicles, it is often seen that the driver opens the escape window to ensure the air quality in the car, but the way of opening the escape window to replace the air can only be carried out in good weather, and it cannot be implemented in rainy weather; moreover, the escape window In the open state, there is a certain degree of danger, which seriously endangers the life safety of the occupants

[0003] Chinese patent 201120009245.2 mentions an air purifier, which mainly works through HEPA filter, ultraviolet light tube and negative ion generator. It i
