Description
Technical field
This utility model relates to a kind of automobile air inlet pipe fitting, the air inlet pipe fitting of a kind of band noise elimination function.
Background technology
Along with socioeconomic development, the living standard of the people is also improving constantly, and automobile has become as people and goes out
One of important vehicles of row.Air inlet pipe fitting is one of requisite parts on automobile, traditional automotive air intake pipe fitting
The most smooth pipeline, owing to installing space is limited, admission line is typically curved shape, and such air inlet pipe fitting has
Air often has when internal circulation to clamor and the noise such as is, and affects riding comfort.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the air inlet of a kind of band noise elimination function
Pipe fitting, its structure is ingenious, reasonable in design, it is possible to elimination air inlet is clamored and is noise effectively, promotes comfort.
The technical scheme provided according to this utility model: the air inlet pipe fitting of band noise elimination function, including pipe fitting body, its feature
It is: air inlet one end of described pipe fitting body is provided with frustum type head, and microcephaly's end seal of described frustum type head is closed, inside frustum type head
Hollow and connecting with pipe fitting body, uniform on the periphery wall of frustum type head is provided with some axial hollow out gaps.
As further improvement of the utility model, the external diameter of the described little head end of frustum type head is not less than outside pipe fitting body
Footpath.
As further improvement of the utility model, the angle of inclination of described frustum type head hypotenuse is 70 ~ 80 °.
As further improvement of the utility model, the angle of inclination of described frustum type head hypotenuse is 75 °.
This utility model compared with prior art, has the advantage that this utility model structure is ingenious, reasonable in design, energy
Enough air inlets of elimination effectively are clamored and are noise, promote comfort.
Accompanying drawing explanation
Fig. 1 is the structural front view of this utility model embodiment.
Fig. 2 is the three-dimensional structure diagram of this utility model embodiment.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the air inlet pipe fitting of the band noise elimination function in embodiment mainly includes pipe fitting body 1, described pipe fitting body
Air inlet one end of 1 is provided with frustum type head 2, and microcephaly's end seal of described frustum type head 2 is closed, frustum type head 2 inner hollow and and pipe fitting
Body 1 connects, and uniform on the periphery wall of frustum type head 2 is provided with some axial hollow out gap 2a.
This utility model is by being provided with frustum type head 2 in air inlet one end of pipe fitting body 1, on the periphery wall of frustum type head 2
Uniform being provided with some axial hollow out gap 2a, such gas axial hollow out gap 2a on frustum type head 2 enters into
After in air inlet pipe fitting, air-flow is disturbance state, will not concentrate the pipe fitting inner wall of impact bending, thus is prevented effectively from that sending clamors cries
Noise.
As it is shown in figure 1, in the present embodiment, the external diameter of the described little head end of frustum type head 2 is not less than the external diameter of pipe fitting body 1,
The tilt angle alpha of described frustum type head 2 hypotenuse is 70 ~ 80 °, preferably 75 °.The design principle of frustum type head 2 is to ensure that on it
The actual internal area sum of all axial hollow out gap 2a, not less than the actual internal area of pipe fitting body 1, does not the most just interfere with
To intake efficiency.
