Description

motorcycle air filter

technical field

The utility model belongs to the technical field of machinery and relates to a motorcycle air filter.

Background technique

With the development of society and the improvement of people's living standards, automobiles, motorcycles, etc. have also become a common means of transportation for modern people to go out every day. At present, motorcycles mostly appear in rural areas and the fringes of cities, where the road conditions are poor and there is a lot of dust. The air filter is a device used to remove particulate impurities in the air. It is mainly used in the fields of starting machinery and internal combustion machinery. Air with impurity particles increases the chance of corrosion and wear. Air filters are also often used in the engine systems of automobiles and motorcycles to purify the air entering the carburetor of the engine and ensure the service life of the engine and carburetor.

Existing motorcycle air cleaner, as shown in Figure 2, comprises an upper housing with an air outlet on the top, a lower housing with an air inlet on the side and a filter element. The upper shell and the lower shell are fastened to form a closed cavity. The filter element is arranged in the cavity and divides the above cavity into an inner chamber and an outer chamber. The air inlet is connected with the outer chamber, and the air outlet communicated with the inner chamber. During the use of the above-mentioned air filter, air enters the outer chamber from the air inlet and is directly filtered through the filter element, and the filtered air enters the inner chamber and is directly discharged from the air outlet into the carburetor. The filter element of the above-mentioned motorcycle air filter is directly set corresponding to the air inlet, which is easily blocked by large particles of impurities such as dust entering with the air, resulting in insufficient air intake, and the noise of the air intake is relatively large, which affects the quality of the air filter. Less efficient, reducing engine and carburetor life.

Contents of the invention

The purpose of this utility model is to solve the above-mentioned problems in the existing technology, and propose a motorcycle air filter. The technical problem to be solved is: the filter element of the existing motorcycle air filter is easily Large particles of impurities such as dust are clogged, the intake noise is louder, the efficiency of air filtration is low, and the service life of the engine and carburetor is reduced.

The purpose of this utility model can be achieved through the following technical solutions: a motorcycle air filter, including a filter element and a housing with an air inlet chamber and an air outlet chamber; Air outlet; the side wall of the housing close to the lower end surface is provided with an air inlet connected to the air inlet chamber; it is characterized in that the filter element is arranged in the air outlet chamber and divides the air outlet chamber into inner The cavity and the external cavity; the air outlet communicates with the external cavity; the air intake cavity communicates with the internal cavity through an air intake pipe.

The housing of the motorcycle air filter is divided into upper and lower two independent chambers. The air enters the air intake chamber from the air inlet on the side wall near the lower end surface of the housing, and then enters the air outlet chamber through the air intake pipe. In the inner chamber, the gas filtered by the filter element enters the outer chamber of the air outlet chamber, and then is discharged into the carburetor through the air outlet. The motorcycle air filter is designed through the improvement, the air inlet and the inlet pipe are intersected, the air enters the air inlet chamber and flows along the air inlet pipe, and most of the large particles of dust sink, so that the dust entering the inner chamber The air contains less dust, which will not cause the blockage of the filter element, greatly improving the efficiency of air filtration, so that the carburetor can always ensure the normal intake air volume, reduce the intake noise, and at the same time ensure Long engine and carburetor life, extended air filter service intervals.

In the motorcycle air filter mentioned above, the housing includes an upper housing, a middle housing and a lower housing; the upper housing and the middle housing are fixedly connected to form an air outlet chamber; the lower housing The shell is fixedly connected to the bottom of the middle shell to form an air intake chamber; the air outlet is located on the top of the upper shell; the air intake is located on the side wall of the lower shell. The housing is divided into an upper housing, a middle housing and a lower housing; the filter element is set in the air outlet cavity formed by the upper housing and the middle housing, and most of the large particles of dust sink after the air enters through the air inlet and enters the outlet air. The filter element will not be blocked after the cavity, which prolongs the maintenance cycle of the air filter and ensures a long service life of the engine and carburetor.

In the motorcycle air filter mentioned above, the air intake pipe is fixedly connected to the lower casing; one end of the air intake pipe is installed in the inner cavity, and the other end is installed in the air intake chamber. And extend below the middle part of the air intake cavity. The end of the air intake pipe extends below the middle of the air intake chamber, and the air enters from the air inlet and then rotates and flows along the air intake pipe, so that there are more large particles of dust that sink, and the dust removal effect is better, and the air entering the air outlet chamber is purer , and less likely to cause filter clogging.

In the above air filter for motorcycles, the bottom surface of the lower casing is detachably connected with the ash storage box. The ash storage box is arranged on the ground of the lower casing, which is conducive to the concentrated collection of the sinking large particles of dust and regular treatment.

In the above motorcycle air filter, the ash storage box is arranged in the middle of the bottom surface of the lower casing. The ash storage box is arranged at the middle position of the bottom surface of the lower housing, which is more conducive to collecting the sinking large particles of dust.

In the above motorcycle air filter, the ash storage box is connected to the bottom surface of the lower housing through bolts and nuts. The ash storage box is connected with the bottom surface of the lower casing by bolts and nuts, and it is easy to install and disassemble when handling dust.

Compared with the prior art, the motorcycle air filter has the following advantages:

1. The shell chamber is divided into upper and lower independent air inlet chambers and air outlet chambers. After the air enters the air inlet chamber, part of the large particles of dust will sink under its own gravity, and the air entering the air outlet chamber is relatively pure and will not cause filter elements clogged.

2. The air inlet and the inlet pipe are intersected, and one end of the air inlet pipe extends below the middle of the air inlet cavity. After entering the air inlet, the air can rotate and flow along the air inlet pipe, so that more large particles of dust can be collected Sinking, it is less likely to cause blockage of the filter element, which greatly improves the efficiency of air filtration, so that the carburetor can always ensure the normal intake air volume, reduces the intake noise, and also ensures the engine and carburetor It has a long service life and prolongs the maintenance cycle of the air filter.

3. The structure is simple, suitable for various motorcycles and motorcycle tricycles, and has good versatility.
