Embodiment 1

[0013] as attached figure 1 As shown, the vehicle-mounted air filter device includes an air outlet pipe 1 with two ends open, and a cover cap 2 is provided on the top of the air outlet pipe 1 .

[0014] as attached figure 1 As shown, the cover cap 2 is a sandwich structure with a cavity 21 in the middle, the inner diameter of the cover cap 2 is consistent with the outer diameter of the outlet pipe 1, and the inner wall of the cover cap is provided with annularly arranged air holes 22, and the air holes 22 and The inner cavity 21 of the cover cap is connected, and the cover cap 2 can slide up and down along the air outlet pipe 1. When the cover cap 2 slides to the bottom, the wall of the air outlet pipe 1 forms a shield for the air hole 22. At this time, the lumen of the air outlet pipe 1 and the cover The inner cavity 21 of the cap 2 is in an isolated state. When the cover cap 2 rises to the top, the air vent 22 is exposed, and the lumen of the air outlet pipe 1 and the inner...

Embodiment 2

[0023] Because the working environment of the vehicle is very different, when the vehicle works in a harsh environment with high dust, such as deserts, coal mines, construction sites, etc., even if the air is pre-filtered, it is inevitable that larger particles will be sucked into the air filter. In order to solve this technical problem, this embodiment makes further improvements on the basis of the device provided in embodiment 1.

[0024] as attached figure 2 As shown, in this embodiment, an oil filter device is provided under the air outlet pipe 1 of the device provided in Embodiment 1. The oil filter device includes an oil storage chamber 13, and the top of the oil storage chamber is connected to the end of the air outlet pipe 1 And the inner cavity of the oil storage chamber 13 is connected with the air outlet pipe 1, and a secondary air outlet pipe 14 is arranged in the oil storage chamber. located inside the oil storage compartment.

Abstract

The invention relates to an air filter device. In order to solve the current technical problem that the vehicle air filter is prone to clogging and failure under harsh conditions, the invention provides a vehicle air filter device, which includes an air outlet pipe, and a cover cap is provided on the top of the air outlet pipe, and the cover The cap is a sandwich structure, the inner diameter of the cap is consistent with the outer diameter of the air outlet pipe, and the inner wall of the cap is provided with circularly arranged air holes, and the air holes are connected with the inner cavity of the cap; the cap is provided with a lifting device, The cover cap can be driven to move up and down on the top of the air outlet pipe by the lifting device; the primary filter element is arranged in the air intake channel at the bottom of the cover cap interlayer, and the ring-shaped inflation tube is arranged in the top cavity of the cover cap interlayer. A number of air nozzles are provided, and the air nozzles point to the primary filter element, and the inflation pipe is connected with the high-pressure air pipe through a flushing electromagnetic valve. The air filter device of the vehicle has a reasonable structure and is easy to operate, and can be widely installed on vehicles that often work in harsh environments.

Description

technical field [0001] The invention relates to an air filter device, in particular to an air filter device for vehicles. Background technique [0002] The car air filter is mainly responsible for removing particulate impurities in the air. When the piston machine is in motion, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The air filter is composed of a filter element and a housing. The main requirements of the air filter are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. At present, the active areas of some heavy trucks are mainly concentrated in some harsh environments with high dust such as construction sites and mining areas. The service life of the air filter is significantly shortened. When the air filter cannot be cleaned or replaced in time, the vehicle will cause serious damage. damage. Contents of the invention [000...
