Air filtering apparatus of motorcycle

Abstract

An air filtration device of a motorcycle comprises a first shell element, a second shell element and a third shell element. The first shell element comprises a base wall, a first surrounding wall, a diaphragm and a vent pipe; the second shell element can be combined with the first shell element and includes a second surrounding wall which can be against and combined with the first surrounding wall of the first shell element; and the third shell element includes a footwall, a first side wall and a second side wall. As the third shell element can be combined through the first shell element, the air filtration device overcomes the trouble caused by improving of the cost and increasing of the assembly work from additionally adding cover body; in addition, the design of the smooth streamline of the first surrounding wall can enhance tight sealing when being against and combined with the second around wall and can not easily cause clearance.

Description

technical field [0001] The invention relates to an air filter device, in particular to an air filter device installed on a motorcycle. Background technique [0002] Generally, motorcycles need to introduce external air to provide engine combustion to generate kinetic energy. However, due to the excessive dust and impurities in the air, the air filter installed on the motorcycle must be used to achieve the effect of clean air. [0003] Such as figure 1 As shown, in the past, a filter 11 commonly installed on motorcycles for filtering air is connected to a hose 12 to bring external air into the filter 11, and then after internal filtering, Fresh air is sent to the engine (not shown), but since the hose 12 is an independent component, it needs to be assembled with the filter 11, the process is more complicated, and the quality of the hose 12 is fragile , are easily damaged by external factors, causing inconvenience in maintenance. [0004] Such as figure 2 , 3 As shown in...

AI Technical Summary

Problems solved by technology

[0005] Even though the air cleaner 13 solves the problem of figure 1 The shown filter 11 causes troubles in maintenance. However, during the assembly process of the air filter 13, it is still necessary to combine the first, second, and third housings 14, 15, and 16 together. Complicated and costly, and, because generally between this first, the third casing 14,16, utilize gasket (not shown) to strengthen the tightness between each other, but this first, the third casing 14,16 The joints of the joints are bent and uneven, so that the gasket cannot be completely tightly fitted on the first and third shells 14, 16, resulting in some gaps, so that dust and impurities in the air can enter the interior through the gaps, resulting in the air filter 13 The effect of waterproof and dustproof is reduced
