Description

Air filter

Technical Field

The utility model relates to an air filter, in particular to an air filter for an air intake system of motor vehicles such as three-wheeled vehicles, trucks, agricultural machinery and the like.

Background

At present, main supporting power of automobiles and agricultural machinery products is a diesel or gasoline engine, the engine sucks a large amount of air in the working process, the working environment of the agricultural machinery products is severe, a large amount of dust and particles exist in the air, if the air is not filtered, the dust particles mixed in the air are sucked into a cylinder of the engine, the abrasion of a piston group and the cylinder can be accelerated, larger particles enter the piston between the cylinders, the phenomenon of serious cylinder pulling can be caused, and the phenomenon is particularly serious in the dry and sandy working environment. In the existing air filter for motor vehicles such as three-wheeled vehicles, trucks, agricultural machinery and the like, outside air directly enters the air filter through an air inlet pipe, and is filtered through a filter element in the air filter. Because the operating environment of agricultural machinery is abominable, only can't carry out effective filtration to a large amount of dust particles in the air through the filter core in the filter, not only the life of filter core is short, also seriously influences the life of engine.

Disclosure of Invention

In view of the above-mentioned drawbacks of the prior art, the present invention provides an air cleaner capable of effectively precipitating dust particles in air and providing clean air for the operation of an engine.

The utility model is realized by the following technical scheme: the utility model provides an air cleaner, includes the main casing body, sets up filter core, first intake pipe, second intake pipe, the third intake pipe in the main casing body, and the vertical setting of first intake pipe is in the outside of the main casing body, and the third intake pipe is located the inside of the main casing body, and first intake pipe and third intake pipe pass through second intake-tube connection, characterized by: the pipe orifice of the second air inlet pipe is communicated with the pipe body part of the first air inlet pipe to form a T-shaped air passage, the lower port of the first air inlet pipe is hermetically connected with a detachable dust removal port, and the dust removal port is communicated with the inside of the first air inlet pipe.

According to the utility model, the T-shaped air passage is formed between the second air inlet pipe and the first air inlet pipe, after external air enters the first air inlet pipe, the air is convoluted and deposited at the lower end of the first air inlet pipe and then flows into the second air inlet pipe, and particle impurities in the air are deposited at the bottom of the first air inlet pipe, so that larger particles and dust in the air are preliminarily filtered. The particle impurities precipitated at the bottom of the first air inlet pipe can be discharged into the dust removal opening, and the dust removal opening can be periodically detached to discharge particle dust. The air after primary filtration enters the air filter again and is filtered for the second time through the filter element, and clean air can be provided for the work of the engine.

Furthermore, in order to facilitate installation and disassembly, the dust removal port is fixedly connected with the first air inlet pipe through a hose clamp.

Furthermore, in order to prevent water from entering the air inlet pipe, a waterproof cap is arranged at the upper end of the first air inlet pipe.

The utility model has the beneficial effects that: the utility model has simple structure, and can make the particles and dust carried in the air form deposition at the position of the air passage where the direction is changed by arranging the T-shaped air passage, thereby preliminarily filtering larger particles and dust in the air, making the air entering the air filter relatively clean, effectively improving the filtering effect of the filter element in the air filter, ensuring that clean air is provided for the work of an engine, greatly prolonging the service life of the filter element and prolonging the service life of the filter. According to the utility model, the detachable dust removal port is arranged at the lower port of the first air inlet pipe, so that the dust removal port can be periodically detached to discharge precipitated dust particles, the operation is simple, and the service life of the filter can be prolonged.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure, the water-proof cap 1, the water-proof cap 2, the first air inlet pipe 3, the second air inlet pipe 4, the third air inlet pipe 5, the dust removing opening 6, the throat hoop 7, the filter element 8 and the main shell.

Detailed Description

The utility model will now be further illustrated by way of non-limiting examples in conjunction with the accompanying drawings:

as shown in the attached drawings, an air cleaner comprises a main shell 8, a filter element 7, a first air inlet pipe 2, a second air inlet pipe 3 and a third air inlet pipe 4, wherein the filter element 7 is arranged in the main shell 8, the first air inlet pipe 2 is vertically arranged outside the main shell 8, and the third air inlet pipe 4 is positioned inside the main shell 8 and is inserted into the lower part of the main shell 8 from the middle of the filter element 7. First intake pipe 2 and third intake pipe 4 pass through second intake pipe 3 and connect characterized by: the pipe orifice of the second air inlet pipe 3 is communicated with the pipe body part of the first air inlet pipe 2 to form a T-shaped air passage, the lower port of the first air inlet pipe 2 is hermetically connected with a detachable dust removal port 5, and the upper part of the dust removal port 5 is communicated with the inside of the first air inlet pipe 2.

In order to be convenient to mount and dismount, the dust removal opening 5 is fixedly connected with the first air inlet pipe 2 through the hose clamp 6.

In order to prevent water from entering the air inlet pipe, a waterproof cap 1 is arranged at the upper end of the first air inlet pipe 2. Waterproof cap 1 covers and establishes in the last port top of first intake pipe 2, leaves the passageway that can supply the air admission between waterproof cap 1 and the last port of first intake pipe 2.

When the engine works, after the engine is started, external air enters the first air inlet pipe 2 through the waterproof cap 1, the air is convoluted and precipitated at the bottom of the first air inlet pipe 2, then reaches the bottom of the air filter through the second air inlet pipe 3 and the third air inlet pipe 4, is filtered by engine oil at the bottom of the main shell 8, and then circulates upwards to be filtered by the filter element 7, and clean air enters the engine from an outlet at the upper end of the air filter. After the air is convoluteed and precipitated at the bottom of the first air inlet pipe 2, precipitated dust particles are gathered at the lower part of the first air inlet pipe 2 and enter the dust outlet 5, the gathered dust particles can be discharged by periodically opening the dust outlet 5, the dust discharging operation is simple, and dust can be discharged easily.

The utility model has simple structure, can make the particles and dust carried in the air form deposition at the position of the air passage where the direction is changed by the T-shaped air passage, primarily filters the air on the premise of not influencing the air inflow, and the primarily filtered air enters the main chamber of the air filter to be secondarily filtered, thereby providing clean air for the work of the engine, effectively protecting the engine and prolonging the service life of the engine.

Other parts in this embodiment are the prior art, and are not described herein again.
