Abstract
The utility model is related to the air inlet pipeline of a kind of integrated resonator and discharge structure, including main line resonant cavity, and resonator is welded on main line bottom, and the main line region of resonator covering has multiple holes densely arranged, and the extreme lower position of resonator is provided with osculum.The hole of large area is provided with pipeline；The bottom of corresponding aperture is resonator, and resonator opens aperture；Air inlet runner is negative pressure when the engine operates, and air-flow enters main line from air inlet and related drain hole, due to the protection of resonator so that the negative pressure of cavity is slightly above main line；When air inlet has water enchroachment (invasion) fashionable, due to large area perforate and Action of Gravity Field, part water is flowed into volume of resonant cavity by main line aperture, is then collected from osculum outflow；When osculum starts there are flowing out, now the pressure and flowpath pressure of resonant cavity are consistent substantially, and because perforated area is very big, the big inflow resonator of water, from osculum discharge.
Description
Technical field
The utility model is related to the air inlet pipeline of integrated resonator and discharge structure.
Background technology
In order to which the inlet noise for reducing gas handling system improves driver comfort, resonator can be added in air filter air inlet pipe
Silencer element, starts the effect for slackening inlet noise；, can be in air filter simultaneously in order to prevent rainy weather water from immersing engine
Assembly lower house relevant position begins to rehearse outlet hole structure.Existing such as Fig. 1, is current dirty air inlet pipe resonator schematic diagram, water is only
The leak from trunnion, the silencer element can not play obvious drainage.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, is that there is provided a kind of new for effective protection filter core inundation
The noise elimination discharge pipe line of type, makes air filter air inlet pipe needs are as much as possible to share drainability.
To achieve the above objectives, the utility model provides a kind of air inlet pipeline of integrated resonator and discharge structure, bag
Main line resonant cavity is included, main line bottom there are multiple holes densely arranged, resonator is uncovered box body structure, is welded in main line
The bottom of hole area, the extreme lower position of resonator is provided with osculum.
It is preferred that, it is made up of, is separated by dividing plate multiple cavities in resonator, the extreme lower position of each cavity is provided with one
Osculum.
It is preferred that, the bore dia >=4mm in described main line region.
It is preferred that, described main line is by upper lower half shell clamping, welding or bolt connection, described resonator and main line
Lower half shell is connected.
The hole of large area is provided with pipeline；The bottom of corresponding aperture is to have multiple cavities in resonator, resonator, and cavity is opened several
Individual aperture, aperture >=4mm；Air inlet runner is negative pressure when the engine operates, and air-flow enters master from air inlet and related drain hole
Pipeline, due to the protection of resonator so that the negative pressure of cavity is slightly above main line；When air inlet has water enchroachment (invasion) fashionable, due to big face
Product perforate and Action of Gravity Field, part water are flowed into volume of resonant cavity by main line aperture, are then collected from osculum outflow；When
When osculum starts there are flowing out, now the pressure and flowpath pressure of resonant cavity are consistent substantially, and due to perforated area
It is very big, the big inflow resonator of water, from osculum discharge.
Compared to current existing cavity resonator structure, its advantage is：
1st, drainage effect is obvious；Its drainage performance≤10%, most of resonator does not possess drainage effect；This is novel porous
Resonant cavity type discharge structure can discharge in gas handling system more than 50% water；So as to reduce the burden of air filter assembly draining；
2nd, simple in construction, technique is uncomplicated；And possess very strong high frequency acoustical absorptivity；
3rd, cost is low；So that the filter core of air filter need not place water felt；
Brief description of the drawings
Fig. 1 is the structural representation of prior art；
Fig. 2 is the structural representation of the inlet pipeline of integrated resonator and discharge structure of the present utility model；
Wherein：
1- pipeline 11- holes 2- resonators
21- dividing plate 22- 2 '-resonators of osculum

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
The air inlet pipeline of a kind of integrated resonator and discharge structure as shown in Figure 2, including the resonant cavity 2 of main line 1, it is humorous
The chamber that shakes is welded on the bottom of main line 1, and the region of main line 1 that resonator 2 is covered has multiple holes 11 densely arranged, and hole is arranged into matrix form
Cloth spreads all over main line region, and with certain intensive, has multiple cavities in resonator 2, separated by dividing plate 21, each cavity
Extreme lower position be provided with an osculum 22.
Main line and the general material of multi-hole resonant cavity are the common plasticses such as PP-T20, PP-T40, PP；Technique be not molded or
Blowing；It is main line for upper lower half shell clamping, welding or mode connects for screw to use injection；Use direct for a pipeline when being blow molded
Blowing is formed；Wall thickness >=2.5mm；Resonator is with main line using welding, such as Vibration welding, hot plate welding；Pipeline region
Porous containing large area, aperture >=4mm, the arrangement in hole and quantity are determined based on acoustic formula；The porous of main line is typically opened in
Pipeline extreme lower position；Each cavity extreme lower position begins to rehearse water hole, aperture aperture >=4mm.
The preferred embodiment that the utility model is created is illustrated above, but the utility model is created not
It is limited to described embodiment, those skilled in the art can be with the premise of without prejudice to the utility model creative spirit
A variety of equivalent modifications or replacement are made, these equivalent modifications or replacement are all contained in the application claim limited range
It is interior.
