Description
Technical Field
The utility model relates to an empty filter of motorcycle.
Background
In recent years, the noise control regulation is continuously revising the noise limit of the motor vehicle, and the intake noise is one of the main noise sources of the motorcycle and is gradually the key control object. An air filter is usually arranged on an engine of a motorcycle, the air filter with a noise elimination structure can play a role in reducing noise, and the use of the air filter becomes an effective method for controlling intake noise. In order to better control the intake noise of the air filter, it is necessary to make extensive research and improvement on the muffling structure of the air filter.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides an air filter of a motorcycle, which controls the air inlet noise through an extended air inlet channel.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides an air filter of motorcycle, is including the casing that is equipped with into, gas outlet, and its inner chamber passes through filter element group spare to be clean chamber and dirty chamber, and the air inlet communicates dirty chamber, and gas outlet intercommunication clean chamber, the gas outlet is located the front end at the casing, and the air inlet sets up at the casing top, installs in it from the air inlet to the honeycomb duct that the casing front end extends, is located the rear of air inlet is equipped with the baffle, and the baffle is equipped with the siphunculus and divides into communicating two parts in front and back with dirty chamber, the filter core of filter element group spare is located the latter half of dirty.
The edge lateral wall of baffle is equipped with the slot, the casing corresponds the slot with the wall of filter element group spare and is equipped with the installation muscle.
The honeycomb duct includes installation department and water conservancy diversion portion, the installation department top is equipped with the brim of a hat that supports and lean on the air inlet top, and the installation department outside still is equipped with the draw-in groove, the protruding inner ring that is equipped with of air inlet inner wall, the installation that realizes the honeycomb duct in the draw-in groove is detained to the inner ring is fixed.
The utility model has the advantages that: the utility model discloses a dirty chamber is divided into communicating two parts around through the baffle, the built-in air drainage that is equipped with the honeycomb duct and will get into the dirty chamber of air filter to the casing front end that is equipped with of first half's air inlet, then the back half that gets into the dirty chamber through the siphunculus of baffle gets into clean chamber after the filter core filters, clean gas after the filtration gets back to the front end by clean chamber rear end again and gets into the engine from the empty filter of gas outlet discharge, form longer inlet channel through above-mentioned structure in limited empty filter inner chamber space and control the noise that admits air, further promote the noise reduction of empty filter.

Detailed Description
Referring to fig. 1 to 3, an air filter of a motorcycle comprises a shell 1 provided with an air inlet and an air outlet 5 and 6, wherein the inner cavity of the shell is divided into a clean cavity 3 and a dirty cavity 4 through a filter element assembly 2, the air inlet 5 is communicated with the dirty cavity 4, the air outlet 6 is communicated with the clean cavity 3, the air outlet 6 is positioned at the front end of the shell 1, the air inlet 5 is arranged at the top of the shell 1, and air can be effectively reduced from entering the air filter through the top of the air filter. A guide pipe 7 extending from the air inlet 5 to the front end of the shell 1 is arranged in the air inlet 5, a partition plate 8 is arranged behind the air inlet 5 to divide the dirty cavity 4 into a front part and a rear part, and the front part and the rear part are communicated through a through pipe 81 on the partition plate 8, so that noise can be better controlled; when air enters the air filter from the air inlet 5 and flows to the front end of the dirty cavity 4 along the flow guide pipe 7, the air turns around and flows to the rear end to flow into the rear half part of the dirty cavity 4 through the through pipe 81 of the partition plate 8, the through pipe 81 can better guide the air to a region with a larger rear half part, the filter element 21 of the filter element assembly 2 is positioned at the rear half part of the dirty cavity 4, all the inflowing air can enter the rear part of the clean cavity 3 after being filtered by the filter element 21 and then is discharged from the air outlet 6 at the front end of the clean cavity 3 to enter the engine, a longer air inlet channel is formed in the limited inner cavity space of the air filter through the structure to control air inlet noise, and the noise reduction effect of the air filter is.
The edge lateral wall of baffle 8 is equipped with slot 82, and casing 1 corresponds slot 82 with the wall of filter element group spare 2 and is equipped with installation muscle 9. When the partition board 8 is installed, the installation ribs 9 are inserted into the slots 82, so that the partition board 8 is installed and fixed, and the installation edge of the partition board 8 is sealed.
As shown in fig. 4, the draft tube 7 includes an installation portion 71 and a flow guiding portion 72, a brim is disposed on the top of the installation portion 71, and the brim abuts against the top of the air inlet 5 when the installation is in place, so that the draft tube 7 can be limited. The mounting portion 71 is provided with a clamping groove 73 on the outer side, the inner wall of the air inlet 5 is convexly provided with an inner ring 51, and the inner ring 51 is buckled into the clamping groove 73 to realize the mounting and fixing of the guide pipe 7, so that the guide pipe 7 is mounted more simply and reliably, and the influence on the noise reduction effect caused by the loosening or falling of the guide pipe 7 can be effectively avoided.
