Abstract
The invention relates to an air purification device for vehicles and particularly relates to an air filter. The air filter comprises a cylindrical shell, wherein an opening is formed in the cylindrical side surface of the shell and serves as an air inlet, a spiral air flue is arranged in the shell, and an outer opening of the spiral air flue is connected with the air inlet; and a filter cotton pillar is connected to the center of the spiral air flue and is of a hollow cylinder structure, and an air outlet pipe is mounted at a hollow part. According to the air filter, air flows into the annular air flue from the air inlet through the opening in the cylindrical side surface of the shell and is decelerated, so that the impact of air on filter cotton is reduced, and the service life of the air filter is prolonged.
Description
Technical field
The present invention relates to a kind of vehicle air purifying device, specially air filter.
Background technology
High ferro or motor-car operationally car body domestic demand keeps the good reliably working ventilated to ensure electric elements.In-vehicle ventilation and air change is by several blower fan forced exhausts on locomotive car body, the side wall shutter air inlet of car body both sides realize.Side wall shutter is equipped with air filter for the sand and dust filtering in air.But owing to speed is very fast, when air intake, wind speed is big, and filtration causes greater impact power.
Summary of the invention
For above-mentioned technical problem, the present invention provides a kind of air purifier little to filtration impact, and concrete technical scheme is:
Air filter, including excessively cylindrical shell, the cylindrical side of described shell has gap, and gap is air inlet, has spiral duct, spiral duct outward opening to be connected with air inlet in described shell；It is hollow cylindrical structure that the connection of spiral duct center has filter cotton post, described filter cotton post, and hollow space is provided with escape pipe.
Described spiral duct sidewall is corrugated.
Gap on the cylindrical side of described shell is hinged with air door plate, and described air door plate free end is towards air inlet.
The air filter that the present invention provides, air is gap on the cylindrical side of shell, enters annular passage from air inlet, the speed of air is reduced, and reduces the air impact to filter cotton, increases the service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The detailed description of the invention of the accompanying drawings present invention, as it is shown in figure 1, air filter, including excessively cylindrical shell 1, the cylindrical side of described shell 1 has gap, and gap is air inlet 5, spiral duct 2, spiral duct 2 outward opening is had to be connected with air inlet 5 in described shell 1；Spiral duct 2 center connects filter cotton post 3, and described filter cotton post 3 is hollow cylindrical structure, and hollow space is provided with escape pipe 4.
Described spiral duct 2 sidewall is corrugated.
Gap on the cylindrical side of described shell 1 is hinged with air door plate 6, and described air door plate 6 free end is towards air inlet 5.
Described air filter, the air outside compartment is gap on the cylindrical side of shell 1, enters annular passage 2 from air inlet 5, the speed of air is reduced, and spiral duct 2 sidewall is corrugated, plays enhancing slowing effect.Enter filter cotton post 3, filter and remove dust, purify air, improve the air quality in workshop.Finally discharge from escape pipe 4.
Gap on the cylindrical side of shell 1 is hinged with air door plate 6, and air stream plays guide effect, can slow down and regulate the effect of air quantity in advance simultaneously.
