Description

Technical Field

[0001] This utility model relates to the field of exhaust emission purification technology, specifically a motor vehicle exhaust emission purifier. Background Technology

[0002] Automobile exhaust is the waste gas produced during vehicle use, containing hundreds of different compounds, including pollutants such as particulate matter, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, and sulfur oxides. While directly harming human health, exhaust fumes also have a profound impact on the environment. Sulfur dioxide in exhaust fumes has a strong, pungent odor and, at certain concentrations, can easily lead to acid rain, causing soil and water acidification and affecting the growth of crops and forests. Currently, purifying automobile exhaust is a technological measure to mitigate its pollution impact. Automobile exhaust purifiers are devices that effectively control vehicle exhaust pollution, reducing emissions of carbon monoxide, black smoke, and other toxic gases.

[0003] However, existing air purifiers are usually one-piece structures. When too many impurities accumulate on the internal filter, it is inconvenient to disassemble and replace it, which leads to a decrease in the purifier's effectiveness and affects its use. Utility Model Content
