Embodiment Construction
[0016] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0017] In the new air intake device in the prior art, since the connecting pipe is arranged between the air intake pipe and the resonance cavity, there are problems of large space occupation and uncompact structure. In order to solve the problems of the prior art, the present invention proposes a new air intake device with a small footprint and a compact structure. The new air intake device includes: an air intake pipe, a first resonant cavity, a second resonant...

The invention relates to a novel air inlet device. The air inlet device comprises an air inlet pipe, a first resonant cavity, a second resonant cavity, a first connecting pipe used for making the airinlet pipe and the first resonant cavity communicate, and a second connecting pipe used for making the air inlet pipe and the second resonant cavity communicate; and the length of a first pipe section, inserted into the first resonant cavity, of the first connecting pipe is the same as the length of a second pipe section, inserted into the second resonant cavity, of the second connecting pipe. According to the novel air inlet device, the connecting pipes are at least partially inserted into the resonant cavities, so that the effect of reducing noise is achieved, the occupied space of the connecting pipes is further reduced, and therefore the overall occupied space of the novel air inlet device is reduced, and the structure is more compact.
Description
technical field [0001] The invention relates to a novel air intake device. Background technique [0002] Generally, the air intake system of a vehicle is used to purify the air entering the engine and suppress the intake noise generated by the engine. The air intake system consists of air intake pipes, air filters and air pipes. In the prior art, in order to reduce the resistance of the air in the pipeline, the air intake pipeline is only set to consider the gas flow inside itself. During the working process of the engine, especially when the load suddenly increases, the intake air flow of the engine will fluctuate greatly, and the engine intake air flow will fluctuate greatly. The air filter device, the air filter, produces noise when it is hit by an unstable air flow. [0003] In order to solve the noise problem, the prior art provides a new type of air intake device with a noise reduction structure, such as figure 1 As shown, the new air intake device includes: an air ...
