Abstract

The utility model discloses an engine noise reduction air filter, which comprises an external tube with one or more than one air inlet and air outlet, a filter element, a filter element fixing device, and a shunting cap and aeration pipes corresponding to the filter element. The utility model is characterized in that the external tube is provided with one or more than one arc-shaped air stream guiding spoiling plate with intrados facing corresponding air inlets and air outlets; as a further improvement of the utility model, cylindrical orifice plates are arranged on the inside of the external tube and on the outside of the aeration pipes and the air stream guiding and spoiling plates; the filter element fixing device comprises a supporting plate fixedly connected with the external tube, one or more than one connecting rods hinged with the supporting plate, and pressing plates hinged with connecting rods; all pressing plates are adhered closely to the filter element, and the end of each pressing plate is assembled on the external tube through bolts and nuts. The engine noise reduction air filter can remarkably reduce noise and increase effective air input with the easily replaceable filter element.

Description

Denoising air filter of engine

Technical field:

The utility model relates to a kind of empty filter that is used for motor.

Background technique:

Existing engine air filter, comprise the urceolus that is provided with one or more suction ports and air outlet, be fixedly mounted on the filter core in each suction port, shunting cap and the breathing pipe corresponding with filter core, this structure one is because no silencer uses the living noise of clock pulse qi of chong channel ascending adversely miscarriage bigger; The 2nd, intake resistance is bigger, and the air air inflow is less during use; The 3rd, filter core is fixedly mounted on each suction port, and is not quick detachable, makes troubles for the maintenance and the replacing of filter core.

The model utility content:

The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of denoising air filter of engine is provided, and it can significantly reduce noise, the effective air inlet amount of increase and filter core and be easy to change.

The purpose of this utility model is achieved in that

A kind of denoising air filter of engine, comprise the urceolus that is provided with one or more suction ports and air outlet, be installed in filter core in each suction port, filter core fixing device, shunting cap and the breathing pipe corresponding with filter core, it is characterized in that in urceolus, being provided with circular arc air-flow guiding and the spoiler of one or more intrados towards corresponding suction port and air outlet;

The utility model is because air-flow leads and the setting of spoiler, and forward unobstructed entering effectively reduces intake resistance in the time of making air inlet, increases effective air inlet amount; When air outlet quick closedown pulsing airflow is reverse, energy choked flow noise reduction;

As further improvement of the utility model, in the urceolus inboard, the gentle conductance of each breathing pipe is to being provided with the cylinder orifice plate with the spoiler outside; When air outlet quick closedown pulsing airflow was reverse, can the resonate unofficial biography of attenuating noise of cylinder orifice plate can also reduce the vibration of empty filter simultaneously;

As further improvement of the utility model, described filter core fixing device comprise the dunnage that connects firmly with urceolus, with the hinged connecting rod more than one or of dunnage, with the pressing plate of every rod hinge connection, all pressing plates are all fitted with filter core, and the end of every pressing plate is installed on the urceolus by bolt and nut; When needing more renew cartridge, but loosen nut is outwards rotated pressing plate, can take out filter core; Filter core after changing is in place, rotates pressing plate and make it be close to filter core, filter core is fixed compresses;

In sum, the utility model can significantly reduce noise, increase effective air inlet amount and filter core is easy to change.

Description of drawings:

Fig. 1 is the utility model embodiment's a structural representation;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the I place enlarged view of Fig. 1;

Fig. 4 is a filter core fixing device user mode reference drawing.

Embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples.

As Fig. 1, Fig. 2 and shown in Figure 3, this denoising air filter of engine, comprise the urceolus 4 that is provided with two suction ports and air outlet, be installed in the filter core 1 in each suction port, filter core fixing device 7, shunting cap 2 and the breathing pipe 3 corresponding with filter core 1, the circular arc air-flow of two intrados towards corresponding suction port and air outlet that is arranged in the urceolus 4 leads and spoiler 5, be arranged on urceolus 4 inboards, each breathing pipe 3 gentle conductance to the cylinder orifice plate 6 in spoiler 5 outsides, wherein filter core fixing device 7 comprises the dunnage 8 that connects firmly with urceolus 4, the two piece connecting rods 9 hinged with dunnage 8, the pressing plate 10 hinged with every connecting rod 9, two pressing plates 10 are fitted with the both sides of filter core 1, and the end of every pressing plate 10 is installed on the urceolus 4 by bolt 11 and nut 12;

Because the setting of air-flow guiding and spoiler 5, forward unobstructed entering effectively reduces intake resistance in the time of making air inlet, increases effective air inlet amount; When air outlet quick closedown pulsing airflow is reverse, can choked flow noise reduction, and can resonate unofficial biography of attenuating noise of cylinder orifice plate 6 can also reduce the vibration of empty filter simultaneously; When needing more renew cartridge 1, as shown in Figure 4, but loosen nut is outwards rotated pressing plate 10, can take out filter core 1; Filter core 1 after changing is in place, rotates pressing plate 10 and make it be close to filter core 1, filter core 1 is fixed compresses.

Claims

1, a kind of denoising air filter of engine, comprise the urceolus that is provided with one or more suction ports and air outlet, be installed in filter core in each suction port, filter core fixing device, shunting cap and the breathing pipe corresponding with filter core, it is characterized in that in urceolus, being provided with circular arc air-flow guiding and the spoiler of one or more intrados towards corresponding suction port and air outlet.

2, denoising air filter of engine according to claim 1 is characterized in that in the urceolus inboard, the gentle conductance of each breathing pipe is to being provided with the cylinder orifice plate with the spoiler outside.
