An air filter device for new energy vehicles

Abstract

An air filter device for new energy vehicles, comprising a vertical pipe, the upper end of the vertical pipe is closed and the lower end is open, and a vertical air inlet pipe is arranged inside the lower end of the vertical pipe, and the lower end of the air inlet pipe and the lower end of the vertical pipe pass through The connecting frame is fixedly connected, the air inlet pipe and the vertical pipe are coaxially arranged, the fan is fixedly installed inside the lower end of the air inlet pipe, and the first sealing ring is arranged inside the lower end of the vertical pipe, and the inner ring of the first sealing ring is connected to the side of the air inlet pipe Contact fit, the outer ring of the first sealing ring is in contact with the inner wall of the standpipe, the upper part of the outer ring of the first sealing ring is provided with several vertical first electric telescopic rods, the lower end of the movable rod of the first electric telescopic rod is connected with the first A sealing ring is fixedly attached to the top. The invention has a simple structure, can realize effective air filtration through multi-stage filtration, and guarantees to provide clean air to the internal combustion engine.

Description

technical field [0001] The invention belongs to the technical field of air filter equipment, in particular to an air filter device for new energy vehicles. Background technique [0002] Air filters are mainly used in pneumatic machinery, internal combustion machinery and other fields to provide clean air for these mechanical equipment, so as to prevent these mechanical equipment from inhaling air with impurity particles during work and increasing the chance of abrasion and damage. The main components of the air filter are the filter element and the casing. The filter element is the main filtering part, which is responsible for the filtration of gas, and the casing is the external structure that provides the necessary protection for the filter element. The working requirement of the air filter is to be able to undertake high-efficiency air filtration work, not to add too much resistance to the air flow, and to be able to work continuously for a long time, but the existing dev...
