Problems solved by technology

When the dining car is driving on the road, there is a negative pressure state or when the door of the dining car is opened and closed, the external pollutant gas will enter the car and cause air pollution in the restaurant, which cannot create a good dining environment for the dining guests.

Abstract

The invention relates to a dining car purifying air by utilizing a directed constant pressure difference, which is used for solving air pollution to external environment and a dining hall due to cooking emission of a kitchen in the dining car. The dining car comprises a car head and a car body, wherein the car body is internally provided with a purifying system, a ventilation system and an automatic pressure difference control system. The purifying system consists of a small-pipe-diameter filter and a large-pipe-diameter filter; the ventilation system consists of a static pressure cavity, a main air pipe and a branch air pipe; the automatic pressure difference control system consists of a pressure difference gauge, a valve switch, a control panel and a fan. The dining car purifying the air by utilizing the directed constant pressure difference can doubly filter and purify the discharged gas when in cooking and external air entering the dining car, so that the pollution of the dining car to the external air and the pollution of external air to the internal air of the dining car can be effectively prevented.

Description

technical field [0001] The invention relates to a dining car, in particular to a dining car which utilizes directional constant pressure difference to realize air purification. Background technique [0002] Mobile food trucks are becoming popular and fashionable, whether in urban areas or in the wild, food trucks can provide consumers with a convenient multi-person dining space. However, while the dining car brings convenience and fashion, there are also some problems. On the one hand, when cooking in the dining car, the polluting gas generated by cooking will be discharged, causing air pollution problems; The polluted air around the road can enter the car without purification. In a document titled Seasonal Trends of Concentration and Size Distribution of Ultrafine ParticlesNear Major Highways in Los Angeles in the journal Aerosol Science and Technology, it is pointed out that whether in summer or winter, when the traffic flow is large, the ultrafine particles on the road ...
