Motorcycle air filter provided with detachable fire-proof plate

Abstract

The invention discloses a motorcycle air filter provided with a detachable fire-proof plate. The motorcycle air filter comprises an air filter casing and a filter element component fixing plate arranged on the casing, wherein the fire-proof plate and a filter element component are arranged in the opening position of the filter element component fixing plate; a limit structure is arranged on the periphery of the opening and limits the fire-proof plate on the filter element component fixing plate; the filter element component comprises a filter element frame and a filter element, and the filter element frame is provided with a plurality of limit posts which are bulged towards an end surface of the fire-proof plate; and when the filter element component is mounted and fixed on the filter element component fixing plate, the limit posts compress the end surface of the fire-proof plate and locate the fire-proof plate in the limit structure in the opening position of the filter element component fixing plate. According to the motorcycle air filter provided with the detachable fire-proof plate, on one hand, a shaking problem which is easily produced by the limit is avoided while assembling problem of the fire-proof plate is solved, on the other hand, when the air filter is maintained, the fire-proof plate not only can be reused to reduce the maintenance cost, but also can be detached conveniently, and dust accumulated in a clean cavity of the air filter can be cleaned out.

Description

technical field [0001] The invention relates to an air filter for motorcycles, in particular to an air filter for motorcycles with a detachable fireproof board. Background technique [0002] The motorcycle air filter is an important component of the motorcycle. Its function is to filter and purify the air entering the motorcycle engine, and to filter out dust and sand in the air. The main structure of the motorcycle air filter includes the housing and the filter element assembly fixing plate set on it. The filter element assembly fixing plate divides the housing into a clean cavity and a dirty cavity. The opening of the filter element assembly fixing plate is fixed with a fireproof plate and a filter element assembly. The outside air enters the dirty cavity from the air inlet of the shell, is filtered by the filter element, enters the clean cavity, and then is sent into the carburetor through the air outlet of the clean cavity to participate in the work of the engine, and th...

Problems solved by technology

Because the filter element assembly will accumulate dust after long-term use, and the filter element assembly can never completely filter the outdoor air, therefore, after the air filter has been used for a period of time, the filter element assembly must be replaced regularly and the fireproof board must be removed to clean the clean chamber

In the prior art, there are usually two ways to fix the fireproof board: one is to clamp and fix the fireproof board directly through the clips and other structures at the opening of the filter element assembly fixing plate, and the other is to solidify the fireproof board and the filter element assembly In the process of air filter maintenance and cleaning, the former fixing method will make it difficult to disassemble the fireproof board, and tools must be used, and the clamping structure will be damaged after dismantling several times, which will affect the clamping effect and cause fire prevention during use. The plate vibrates and generates noise; although the latter fixing method is convenient to disassemble, the fire plate will also be replaced when the filter element assembly is replaced, which virtually increases the cost of daily maintenance for users
