Abstract
The utility model supplies an automobile air filter improved structure, which comprises a shell, a shell cover and a filter component. The filter component is embedded in the shell and the shell cover, forming a filter front cavity and a filter back cavity. The air inlet pipe is communicated with the filter front cavity, the air outlet pipe is communicated with the filter back cavity, the front end of the air inlet pipe appears in bell-mouth shape, the back end appears in S-shape inlet passage; a shell concave-shape part used to cushion inlet air flow is arranged on the filter front cavity, the air inlet noise can be reduced, the sealing performance of the air filter is improved, impurities in the air are filtered out , so that the fresh clean air comes into the engine via the air outlet pipe, which ensures the engine work normally in the state when various indexes are guaranteed.
Description
Technical field
The utility model relates to a kind of air-strainer, is meant a kind of structure-improved of air filter for automobile especially.
Background technique
Air-strainer is one of indispensable key components and parts on the automobile, and to the raising of automobile emission and noise reduction requirement, the combination property of its air-strainer also must improve along with in the world.Air-strainer closes as first of engine aspirating system, its role is to, the airborne impurity of filtering, make the air of fresh cleaning enter motor by steam outlet pipe, make motor proper functioning under the state that guarantees every index, and can play induction noise is decreased, and the air-strainer limit value that pass-by noise reaches when automobile gives it the gun is unsatisfactory at present; On the other hand, the sealing of air-strainer is that the housing by air-strainer engages to be adjacent to cap, filter core and reaches, and sealability also must further improve.
The model utility content
At the defective that technique scheme exists, the purpose of this utility model is to provide a kind of structure-improved of air filter for automobile, can reduce inflow noise, guarantees the sealability of air-strainer.
For achieving the above object, be achieved by the following technical solution:
The structure-improved of air filter for automobile, form by housing, cap and filter core, filter core is built in housing and cap the inside, form filter cleaner ante-chamber and filter cleaner back cavity, suction tude connects the filter cleaner ante-chamber, steam outlet pipe connects the filter cleaner back cavity, and it is characterized in that: described suction tude front end is broadening formation, the S-type gas-entered passageway in its rear end; Housing matrix position in order to the buffering charge air flow is set on the filter cleaner ante-chamber.
The multiple filtering layer that described filter core adopts on it make up compound filter cloth by once injection moulding in plastic frame, plastic frame is equipped with belt seal ring.
Adopt the air filter for automobile of said structure, adopt the horn-shaped port air inlet at the suction tude front end, S-type gas-entered passageway has been adopted in the rear end, after when motor is being worked, from atmosphere, sucking air, air-flow enters from empty filter suction port, enter tracheae by S type passage, make it the noise that air inlet produces is decayed, air-flow obtains buffering again by the filter cleaner ante-chamber at housing matrix position, makes its secondary noise reduction, air-flow passes through filter element filtering again, filtering airborne impurity, make the air of fresh cleaning enter motor by steam outlet pipe, make motor guarantee proper functioning under the state of every index; In addition, the filter core of once injection moulding, periphery has plastic frame, is convenient to the installing ring RunddichtringO, makes the sealability of this product more excellent more fine than other common empty filters.

Fig. 2 is a top perspective view of the present utility model;
Fig. 3 is a perspective bottom view of the present utility model.
Embodiment
As shown in Figure 1, 2, 3, the structure-improved of air filter for automobile, form by cap 1, housing 2 and filter core 3, filter core 3 is built in cap 1 and housing 2 the insides, form filter cleaner ante-chamber 4 and filter cleaner back cavity 5, suction tude 6 connects filter cleaner ante-chamber 4, and steam outlet pipe 7 connects filter cleaner back cavity 5, suction tude 6 front ends are broadening formation, the S-type gas-entered passageway in its rear end; Housing matrix position 8 in order to the buffering charge air flow is set on the filter cleaner ante-chamber 4, and is streamlined transition.Adopt the air filter for automobile of said structure, when motor sucks air from atmosphere when 1 does after, air-flow enters from empty filter suction port, enter tracheae by S type passage, make it the noise that air inlet produces is decayed, air-flow is again by filter cleaner ante-chamber 4, obtain buffering at housing matrix position 8, make its secondary noise reduction, air-flow filters by filter core 3 again, filtering airborne impurity, make the air of fresh cleaning enter motor by steam outlet pipe 7, make motor guarantee proper functioning under the state of every index.
As shown in Figure 1, the multiple filtering layer that filter core 3 adopts on it make up compound filter cloth by once injection moulding in plastic frame 31, plastic frame 31 is equipped with the seal ring 32 that goes in ring, and makes the sealability of this product more excellent more fine than other common empty filters.
Claims (2)
1, the structure-improved of air filter for automobile, form by housing, cap and filter core, filter core is built in housing and cap the inside, form filter cleaner ante-chamber and filter cleaner back cavity, suction tude connects the filter cleaner ante-chamber, steam outlet pipe connects the filter cleaner back cavity, and it is characterized in that: described suction tude front end is broadening formation, the S-type gas-entered passageway in its rear end; Housing matrix position in order to the buffering charge air flow is set on the filter cleaner ante-chamber.
2, the structure-improved of air filter for automobile as claimed in claim 1 is characterized in that: the multiple filtering layer that described filter core adopts on it make up compound filter cloth by once injection moulding in plastic frame, plastic frame is equipped with ring-like seal ring.
