Abstract
The invention relates to an engine water medium air filter, comprising a filter box body, a box cover, a backwashing cover, a water fog proof layer, a wave-proof layer, an air inlet pipe, an air outlet and water which is taken as the filtration medium. The outlet of the air inlet pipe is provided with an airflow backwashing cover; the middle part of the box body is provided with the water fog proof layer and the wave-proof layer; an airflow clearance is arranged between the water fog proof layer and the wave-proof layer; a plurality of zigzag airflow passages which are formed by the connection of V shape, W shape or multi-V shape are arranged in the water fog proof layer and the wave-proof layer for the pass of airflow. The air filter has obvious filtration effect and extremely small air resistance, can effectively ensure the air intake of the engine, and improves the power of the engine. Furthermore, the invention has simple structure, takes the water as the filtration medium without a filter core, greatly reduces the usage cost compared with a filter of which the paper filter core is frequently replaced, and plays a role in saving energy and reducing exhaust owning to complete combustion of the fuel of the engine and fine exhaust of tail gas.
Description
Technical field
The invention belongs to the air filter unit technical field, being specifically related to a kind of is the air filter of medium with water, is widely used on the motor of automobile, motorcycle and some general dynamic machineries.
Background technique
What its filter medium of existing air filter for engine generally adopted is the papery filter core, and its advantage is that filtering effect is better, moulding easily, and material is lighter.But also come with some shortcomings, mainly show: the one, it is bigger that the air communication of filter paper is crossed resistance, can influence the air inflow of motor, reduces the output power of motor; Two are to use the life-span short, use airborne dust impurity of a period of time will be deposited on the filter paper, stop up filter opening, further strengthened gas-flow resistance, reduced air input of engine by air, therefore must be often renew cartridge more, thereby cause the increase of user cost, the wasting of resources etc.
Summary of the invention
The objective of the invention is to deficiency at present papery filer element type air filter existence, a kind of aqueous medium aerofilter of engine is proposed, with water is filter medium, gas-flow resistance is minimum, guarantee the air inlet demand of motor, prolong the working life of empty filter, reduce user cost, economize on resources.
Technological scheme of the present invention is as follows:
A kind of aqueous medium aerofilter of engine comprises filter box-body, case lid, suction tude and the air outlet that is connected with motor etc.Characteristics of the present invention are that water is equipped with in the bottom in filter box-body, and suction tude puts in the filter box-body, and its outlet end upwards is exposed to the water surface, at the outlet end of suction tude air-flow recoil cover are installed, and air-flow recoil cover below communicates with the water surface, and leaves certain interval.At the filter box-body middle part anti-water smoke layer is installed, is distributed with in this anti-water smoke layer and holds the tortuous air-flow path that air communication is crossed.The air outlet of filter is arranged on the filter cabinet body wall or case lid of the above air ventilation layer of anti-water smoke layer.This sky filter is filter medium with water, and the air back-pressure that will enter at a high speed by air-flow recoil cover is dashed boiling to water to the water surface, and the impurity of dust in air is dissolved in the water, and air is played a role in filtering.Simultaneously for fear of water by high speed airflow inspiration motor, also in order to prevent that extraneous vibrations (as the braking of automobile) from causing the water wave, make water enter motor, the present invention is on the water surface, the middle part of filter is provided with anti-water smoke layer, stops water smoke by the tortuous air-flow path of preventing the water smoke layer, clears up the upthrust of water wave, thereby effectively avoid water to enter motor, guarantee the safe operation of motor with air-flow.Because the air-flow path of anti-water smoke layer is more much bigger than the filter opening of paper filter element, therefore very little to gas-flow resistance, its resistance of air almost can be ignored, and therefore can effectively guarantee the air inlet of motor, improves the output power of motor.
Further, in order to increase anti-water smoke layer water smoke in the air-flow stopped the decomposition effect, the air-flow path that the airpath design that preferably will prevent the water smoke layer becomes V-type, W type or many V-types to connect, under the situation of space permission, roll over The more the better, and the angle that the parallel axes of the axis of the upper end of passage outlet and filter air outlet intersects in obtuse angle, further increases Security.
In order to reach the effect of better waterproof wave, also can between air-flow recoil cover periphery and filter cabinet body wall, anti-ware layer be set, also be distributed with in the anti-ware layer and hold the tortuous air-flow path that air communication is crossed, preferably air-flow path is a V-type, and preferably the lower end import of the air-flow path of this anti-ware layer is tilted towards the filter cabinet body wall.
Install for convenience, anti-ware layer and the design of anti-water smoke layer one can be integrated into a core body assembly structure with them, be assemblied in the casing by waterproof grommet.
The dismounting clean and maintenance can play the outer wall employing sliding connection of air-flow recoil cover with the outlet end of suction tude to the autoregulation of air output size with water surface gap simultaneously again for convenience, guarantees the strength that air recoils, and improves filtering effect.
As seen, the air filter that the present invention proposes has significant filtering effect, and resistance of air is minimum, can effectively guarantee the air inflow of motor, improves the power of motor, reduces the consumption of fuel oil, plays energy-conserving action.This air filter arrangement is simple in addition, is filter medium with water, does not have filter core, is significantly less than the user cost of frequent replacing papery filer element type filter, and because the oil inflame of motor is abundant, exhaust emissions is good, plays the effect of energy-saving and emission-reduction.
This air filter is used through going up in compact car (Hainan Pu Lima), on same road surface, with same speed, by same driver's test run many times, the result shows, because resistance of air is minimum, than papery filer element type filter fuel-economizing about 11%, automatically urgent under 160 kilometers speed per hours, automobile is safe and sound.
