Abstract
The utility model provides an automobile plastic air filter, place chamber, empty filter core, air filter end cover, air inlet, outlet duct including empty filter casing, empty filter core, its air inlet places the chamber intercommunication through admitting air resonant cavity and empty filter core. The automobile plastic air filter is characterized in that a pressure stabilizing cavity communicated with the upper part of the filter element placing cavity of the air filter is arranged on the upper part of the filter element placing cavity of the air filter, and the air outlet pipe extends out of the pressure stabilizing cavity. The communicating opening of the air inlet resonant cavity and the air filter element placing cavity is inclined downwards, and an angle beta of 75-80 degrees is formed between the communicating opening and the vertical direction. The air filter end cover and the air filter shell are assembled in an inserting mode and are buckled and locked through 4 buckles, and a rubber sealing strip is arranged between the air filter end cover and the air filter shell for sealing. The bottom of the air inlet resonant cavity is provided with 2 drain holes, and rubber plugs are arranged outside the drain holes. The utility model discloses organize the air inlet flow field better, reduce the resistance of admitting air and admit air the noise, improve the efficiency of admitting air, make the combustion of liquid gas more abundant in the engine, ensured the output of engine power and moment of torsion.
Description
Technical field
The utility model relates to a kind of auto parts and components, specifically, is a kind of automobile plastic air filter.
Background technique
The light commercial vehicle air filter mostly is the metal air filter, and air filter housing, end cap, suction tude, steam outlet pipe are steel pipe or steel plate punched moulding.Because the metalwork moulding is relatively difficult, metal air filter turnover gas channel structure is simple, and the air filter body can't be organized inlet flow field without resonant cavity and pressure stabilizing cavity, and intake resistance and induction noise are large, and intake efficiency is low; Air filter is without water removing structure, in case rain enters air filter inside, can cause filter core to damage; The means of fixation of cleaner cartridge cleaner is complicated, maintenance is convenient not.And the general volume of metal air filter is large, quality heavy, the exterior quality sense is low.
Summary of the invention
The purpose of this utility model is to solve the prior art problem, and a kind of plastic air filter device is provided, and this air filter has resonant cavity and pressure stabilizing cavity, can organize Inlet Swirl, reduces intake resistance and induction noise, has except water function the protection cleaner cartridge cleaner.This air filter has the characteristics such as volume is little, lightweight, handsome in appearance, the filter core maintenance is convenient simultaneously.
The technical solution of the utility model is as follows: automobile plastic air filter of the present utility model comprises air filter housing, cleaner cartridge cleaner placed cavity, cleaner cartridge cleaner, air filter end cap, suction port, steam outlet pipe, and its suction port is communicated with the cleaner cartridge cleaner placed cavity by air inlet resonant cavity.
Described automobile plastic air filter has the pressure stabilizing cavity that is communicated with it on cleaner cartridge cleaner placed cavity top, and steam outlet pipe stretches out through pressure stabilizing cavity.
The connecting port of described air inlet resonant cavity and cleaner cartridge cleaner placed cavity is downward-sloping, becomes ° angle, β=75～80 with Vertical direction.
Described air filter end cap and air filter housing are the plug-in type assembling, withhold locking by 4 buckles, have rubber weather strip to seal in the middle of air filter end cap and the air filter housing.
The bottom of described air inlet resonant cavity has 2 weep holes, and rubber plug is housed outside weep hole.
The beneficial effects of the utility model: the utility model utilizes plastics to be easy to the characteristics of molding and forming, integrated resonant cavity and pressure stabilizing cavity, by admission line structure organization Inlet Swirl, reduce intake resistance and induction noise, provide cleaning, clean fresh air to motor, make in the motor liquid gas firing more abundant, ensured the output of engine power and moment of torsion, reduced the oil consumption of motor and discharge pollutants.Assembling and the sealing means of the utility model air filter end cap and air filter housing are simple, firm.The utility model has designed discharge structure, the protection cleaner cartridge cleaner.Simultaneously the utility model plastic air filter utensil has compact structure, the characteristics such as lightweight, handsome in appearance.
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
Fig. 2 is schematic perspective view of the present utility model.
Fig. 3 is the partial enlarged drawing of Fig. 1.
Fig. 4 is the partial enlarged drawing of Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, automobile plastic air filter of the present utility model comprises air filter housing 1, cleaner cartridge cleaner placed cavity 2, cleaner cartridge cleaner 3, air filter end cap 4, suction port 5, steam outlet pipe 6, and its suction port 5 is communicated with cleaner cartridge cleaner placed cavity 2 by air inlet resonant cavity 7.
On cleaner cartridge cleaner placed cavity 2 tops the pressure stabilizing cavity 8 that is communicated with is with it arranged, steam outlet pipe 6 stretches out through pressure stabilizing cavity 8.Cleaner cartridge cleaner 3 is fixed on housing interior the cleaner cartridge cleaner placed cavity 2 and the scaffold 13 between the pressure stabilizing cavity 8, and the two ends of cleaner cartridge cleaner 3 are rubber seal.Pressure stabilizing cavity and air inlet resonant cavity have increased the volume of air filter together, can organize Inlet Swirl, reduce intake resistance, reduce induction noise.
Described air inlet resonant cavity 7 is downward-sloping with the connecting port 9 of cleaner cartridge cleaner placed cavity 2, becomes ° angle, β=75～80 with Vertical direction.This cuts sth. askew to air intake structure, when reducing intake resistance, makes the large particle dust separation in air filter end cap 4 by the flowability of gas, has improved filtering efficiency and the working life of air filter.
Fig. 3 is the partial enlarged drawing of Fig. 1: described air filter end cap 4 assembles for plug-in type with air filter housing 1, withholds locking by 4 buckles 10, has rubber weather strip 11 to seal in the middle of air filter end cap 4 and the air filter housing 1.When making cleaner cartridge cleaner 3 and safeguard, only need unclamp buckle 10 and take off air filter end cap 4 and can extract cleaner cartridge cleaner 3, very convenient.
Fig. 4 is the partial enlarged drawing of Fig. 2: the bottom of described air inlet resonant cavity 7 has 2 weep holes 12, and rubber plug 14 is housed outside weep hole 12.Utilize the gravity separation principle, water is converged amass in the bottom of air inlet resonant cavity 7, discharge from weep hole 12, prevent that cleaner cartridge cleaner 3 is subject to the infringement of rainwater, shields to cleaner cartridge cleaner 3.A rubber plug 14 is housed outside weep hole 12, prevents that dust from entering air inlet resonant cavity 7 from weep hole 12.
