A lateral air inlet unit is arranged on the side wall of the outer cylinder. The inner side of the outer cylinder is covered with a layer of sheet metal provided with a round through hole. By the adoption of the structure, the air inflow of an engine air filter can be effectively increased, and the noise pollution of an engine can be effectively reduced. Furthermore, the structure is simple, low in manufacturing cost and convenient to install and use.
Description
Technical field
The present invention relates to a kind of air filter, specifically a kind of air filter of engine structure strengthening air inflow.
Background technique
Existing air filter of engine, comprise with two suction ports and the urceolus of some air outlets, the filter core be fixedly mounted in each suction port, the shunting cap corresponding with filter core and breathing pipe, this structure is due to without silencer, and the noise that during use, pulse air miscarriage is raw is very large; And often occur in motor that lack of air causes insufficient situation of burning because suction port blocking is obstructed.Although it is perfect that prior art constantly carries out improvement to air filter, fail all the time thoroughly to reach reduction noise, increase the object of air inlet amount simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of air filter of engine structure strengthening air inflow, solve engine intake blocking in prior art be obstructed after deficiency of air cause burning insufficient, and the problem that air filter noise is excessive, realize increasing the object that air inlet amount reduces noise simultaneously.
The present invention is achieved through the following technical solutions:
Strengthen an air filter of engine structure for air inflow, comprise with two suction ports and some air outlets urceolus, be arranged on filter core, filter core fixing device after each suction port, the sidewall of described urceolus is provided with a side air inlet system.Described side air inlet system comprises cover plate, side suction port, is arranged on side filter core after the suction port of described side, the survey face filter core fixing device for fixing described side filter core, the spoiler be fixedly connected with described side filter core and the breathing pipe being connected to spoiler end; The sheetmetal of one deck band circular perforations is covered with in the inner side of described urceolus.In working order, air, except entering from existing suction port, can also enter in urceolus through side air inlet system, and by entering outer barrel after filter element filtering, thus solve the problem of the amount of supplied air deficiency when existing suction port is obstructed; In addition, the noise waves produced is passed to the band circular perforations sheetmetal inside urceolus, causes thin plate to resonate, thus realizes the significantly weakening to acoustic wave energy, reduces noise pollution.
Concrete, be covered with the sheetmetal with circular perforations described in one deck in the inner side of described urceolus, described circular perforations aperture is 1 ~ 3mm and is random distribution.Metallic sheet stock intensity is high, high temperature resistance, long service life, not fragile, be preferably galvanized sheet, aluminium sheet or corrosion resistant plate.Relative to rectangle or polygonal perforation, circular perforations can increase area of passage, prevents air from resonant cavity, compressing accumulation.Under the condition that orifice plate thickness is certain, the aperture of different pore size has different natural frequencys, when external sound wave frequency is identical with its natural frequency, resonance phenomenon will be produced, at this moment thin plate amplitude reaches maximum, in aperture, the reciprocating speed of air is maximum, and frictional loss is maximum, and the acoustic energy of absorption also reaches maximum value.For air filter of engine, its noise produced is based on low frequency range noise, and its natural frequency of circular perforations sheetmetal of aperture 1 ~ 3mm is also within the scope of low-frequency range, can make resonant cavity under the sound wave effect of multiple low-frequency range, all can realize the resonance of subrange, thus strengthen resonant cavity frequency of noise elimination scope, weaken the noise of the different frequency produced in air filter working procedure to the full extent.
Further, the body of described breathing pipe increases gradually to end face latus rectum of giving vent to anger, and to reduce the air velocity entering air filter, reduces acoustic wave energy, reduces noise.
The present invention compared with prior art, effectively can improve the air inflow of air filter of engine, reduce engine noise pollution, and structure is simple, low cost of manufacture, is convenient to installation and use.

Embodiment
Clearly understand for making the object, technical solutions and advantages of the present invention, below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, and exemplary embodiment of the present invention and explanation thereof are only for explaining the present invention, not as a limitation of the invention.
A kind of air filter of engine structure strengthening air inflow, as shown in Figures 1 and 2, comprise the urceolus 4 with two suction ports and some air outlets, be arranged on the filter core after each suction port, filter core fixing device, the sidewall of described urceolus 4 is provided with a side air inlet system 8, described side air inlet system 8 comprises cover plate 7, side suction port 6, be arranged on the side filter core 1 after the suction port of described side, for the survey face filter core fixing device 5 of fixing described side filter core 1, the spoiler 2 be fixedly connected with described side filter core 1 and be connected to the breathing pipe 3 of spoiler 2 end.The inner side of described urceolus 4 is covered with the sheetmetal 9 of one deck with circular perforations, and described aperture is 1 ~ 3mm, and described sheetmetal is preferably galvanized sheet, aluminium sheet or corrosion resistant plate.In air filter of engine working procedure, by closing cover plate 7, side air inlet system 8 can be stopped using; By opening cover plate 7, can make side air inlet system 8 and existing suction port common admission, for motor provides more filtered air, the situation that when preventing the blocking of existing suction port to be obstructed, engine interior burns insufficient because of lack of air occurs.Due to the noise mainly low-frequency sound wave that air filter of engine produces, and described aperture is that the natural frequency of perforated metal thin plate 9 in 1 ~ 3mm pore diameter range is also within the scope of low-frequency range, under sound wave effect, sheetmetal resonates, amplitude reaches maximum, and in aperture, the reciprocating speed of air is maximum, and frictional loss is maximum, the acoustic energy absorbed also reaches maximum value, thus effectively reduces noise pollution.In addition, when air outlet quick closedown, air-flow oppositely produces pressure excitement, can produce larger instantaneous noise in air filter, and the sheetmetal 9 overlaying on the band circular perforations inside urceolus 4 can resonate, the unofficial biography of attenuating noise, avoid instantaneous noise excessive.The body of described breathing pipe 3 increases gradually to end face latus rectum of giving vent to anger, and can reduce the air velocity entering air filter, reduces acoustic wave energy, reduces noise.
Above-described embodiment; object of the present invention, technological scheme and beneficial effect are further described; be understood that; the foregoing is only the specific embodiment of the present invention; the protection domain be not intended to limit the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
