Automobile air purifier

Abstract

The invention provides an automobile air purifier. The automobile air purifier comprises a shell (1), a filter (2) and a fan (3). The shell has a main body (12) and a cover (11) having a central region (111) and a peripheral region (112). The filter (2) is contained in the shell (1) and used for purifying air. The fan (3) is removably engaged with the main body (12) of the shell (1) and is configured to force an external air to flow from the central region (111) of the shell (1), through the filter (2), and then escape from the peripheral region (112) of the shell (1). The automobile air purifier can be used under the power-on and power-off conditions, the maximum loading ratio can be achieved, and therefore enough filtering materials can be loaded to prolong the service life of the filter. The air purifier is compact in overall structural design and convenient to carry.

Description

Technical field [0001] The present invention relates to the technical field of air purifiers, and more particularly to a car air purifier. Background technique [0002] The car air purifier is an electrical appliance for a car, its purpose is to remove air pollutants, including particulate contaminants and gas contaminants caused by internal decorative volatilization, car exhaust gas, smoking and external leakage, to protect the driver And the health of passengers. [0003] Currently, automotive air purifiers generally include electronic control systems, air circulation systems (divided into suction ports, airways, outlets and fans) and filtration systems. These complex systems are connected to each other through housing and various connecting firmware to achieve air purification. The fan is used to drive air to form the airflow in the desired direction. The filtration system is used to absorb particulate contaminants and harmful gas substances. The electronic control system is u...

AI Technical Summary

Problems solved by technology

Typically, these systems, connecting fasteners, and housings are often divided into dozens of components, resulting in a complex structure that is generally not portable

[0004] Generally, the air purifier only needs to replace its filter to prolong its service life, while keeping the housing, fan, air circulation system and control system unchanged, but the filter is usually small relative to the total volume of the air purifier, resulting in a filter Insufficient amount of cleaning material loaded in the filter, which limits the service life of the filter

[0005] Also, one of the main problems with using car air purifiers is that they run on electricity to operate and are ineffective without it

Because the car is parked most of the time, the air purifier is ineffective most of the time

At the same time, particulate and gaseous pollutants are usually released to some extent continuously during the parking process, which can be harmful to passengers once they enter the car before the air purifier is powered on to start cleaning the particulate and gaseous pollutants
