Abstract
An air filter of vehicles for gasoline engines comprises a shell with an air inlet and an air outlet. A pyramidal-platform-formed air strainer is provided in the shell, which is characterized in that a conical dome is provided on the top of the pyramidal-platform-formed air strainer. The tip of the dome is in the different direction as airflow, forming a windward side of the air strainer. Being the best configuration, a conical dome is provided with the inside of pyramidal-platform-formed air strainer. The tip of the dome is in the same direction as airflow. The utility model improves the chaotic condition the airflow flows inside the air filter, and downsizes the flow resistance of the airflow, not only reducing the noise, but also having effort on improving the intake flowrate.
Description
Technical field
The utility model relates to the air-strainer that is applied to automotive gasoline engine.
Background technique
In order to promote the power of automotive gasoline engine, prior art provides a kind of air-strainer of high flow capacity.This air-strainer comprises a shell that has suction port and air outlet, is provided with the air filter screen of cone table shape in the shell, and the little table top in frustum top is towards suction port.Air enters from the suction port of air-strainer, behind the conical surface and the filtration of little table top of frustum, sends from the air outlet of air-strainer.The shortcoming of this air-strainer is that noise is big, because the little table top of frustum and air be bump head-on, produce noise, and collide mutually from the air that little table top and the conical surface are got in the frustum simultaneously, it is chaotic to flow, also can produce noise, particularly when motor is opened the throttle, when air inflow increases, the noise that sends is more remarkable.
Summary of the invention
The purpose of this utility model is that above-mentioned air-strainer is improved, and the air-strainer that a kind of throughput is big, noise is little is provided.
The utility model is achieved in that the air-strainer of motor petrol motor comprises a shell that has suction port and air outlet, be provided with the air filter screen of cone table shape in the shell, especially, roof anchorage at the cone table shape air filter screen has coniform air guide sleeve, the tip of air guide sleeve constitutes the windward side of filter screen in face of the air draught direction.When air process cone table shape filter screen, air guide sleeve makes the noise that facings the wind of filter screen reduce greatly, and simultaneously, the air guide sleeve limit air can only enter frustum from the conical surface, improved the situation of air flows confusion, so the utility model can reduce the noise of air-strainer.
The utility model has the advantages that: owing to improved the air chaotic situation that in air-strainer, flows, air flow resistance is reduced, so the utility model not only can reduce noise, and to the air inflow effect of haveing a certain upgrade.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Referring to Fig. 1, air-strainer comprises a shell 3 that has suction port 1 and air outlet 2, and shell 3 internal fixation have the air filter screen 4 of cone table shape.Filter screen 4 can adopt the cone table shape filter screen identical folded structure used with existing air-strainer, but the little table top in the top of frustum no longer needs to be provided with filter screen.Roof anchorage at filter screen 4 has coniform air guide sleeve 5, and the tip of air guide sleeve 5 constitutes the windward side of filter screen 4 in face of the air draught direction.Under the effect of air guide sleeve 5, not only reduced the noise that facings the wind of filter screen 4, and limited air and can only enter frustum from the conical surface, what make air mobilely has a regularity, reduces the noise that the air collision is sent.
As further improvement, present embodiment has another coniform air guide sleeve 6 in the internal fixation of cone table shape air filter screen 4, and the tip of air guide sleeve 6 is along the air draught direction.Under the effect of air guide sleeve 6, mobile the have more regularity of air in cone table shape filter screen 4, flow resistance and noise also further reduce.
Heat-resistant materials such as two air guide sleeve 5,6 available metals, nylon, plastics are made.Slick and sly streamline also can be adopted in the tip of two air guide sleeves except illustrated sharp shape.
Claims (2)
1, a kind of air-strainer of motor petrol motor, comprise a shell that has suction port and air outlet, be provided with the air filter screen of cone table shape in the shell, it is characterized in that: the roof anchorage at the cone table shape air filter screen has coniform air guide sleeve, the tip of air guide sleeve constitutes the windward side of filter screen in face of the air draught direction.
2, air-strainer as claimed in claim 1 is characterized in that: the internal fixation at the cone table shape air filter screen has another coniform air guide sleeve, and the tip of this air guide sleeve is along the air draught direction.
