Description
Technical field
The utility model relates to a kind of air filter, particularly a kind of four-stroke horizontal-shaft engines air filter.
Background technique
At present, motor used in existing four-stroke horizontal axis, the filter core in its air filter is vertical setting.The utility model patent that a kind of name is called " Universal gasoline engine air filter " is disclosed in CN202851205U, it comprises air filter housing, is respectively arranged with air inlet button and air outlet in the upper and lower both sides of air filter housing, arranges filtering dust assembly in the inside of air filter housing; Described filtering dust assembly comprises frame of filter element, is socketed in the foam filter elements of frame of filter element outer end and is socketed in the paper filter element of frame of filter element inwall, is respectively equipped with the lower sealing cover for sealing filtering dust assembly in filtering dust assembly lower end; An annular gas ash disengagement chamber is formed between the inwall of air filter housing and filtering dust assembly; Described suction port and gas ash disengagement chamber is connected, and suction port is tangent with the grey disengagement chamber of gas; Be provided with the air outlet with the intracavity inter-connection of paper filter element in the lower end of air filter housing, described air outlet channel is communicated with air outlet.In CN202250490U, disclose a kind of name be called that " a kind of gasoline engine air filter " is utility model patent, it comprises supporting base, column is shaped with in the middle of supporting base, supporting base side has air door switch groove and oil switch groove, the opposite side of supporting base is shaped with connecting base, connecting base has fixed hole and air outlet hole, supporting base fixes through the fixed hole of connecting base and Carburetor, supporting base is installed filter core baffle plate, in filter core baffle plate, netted inlet hole and bumping post are installed, hole is opened in bumping post, filter core baffle plate is installed filter core frame, mounting hole is had in filter core frame, in filter core frame, filter core is installed, return-air hole is shaped with in the middle of filter core, the bumping post of filter core baffle plate inserts in return-air hole through through hole, outer cover is installed outward at filter core frame and filter core, knob installed by outer cover, column in supporting base is through through hole, mounting hole is tightened mutually with return-air hole and knob.Although the air filter of above-mentioned two patents all can be filtered air, but consider the compactedness of complete machine, the filter core height that in above-mentioned two patents, air filter is vertically arranged is restricted, effective admission area is little, cause intake efficiency low, filter core is short for working life, thus affects power performance and the economic performance of complete machine.
Model utility content
The purpose of this utility model is just to provide the high four-stroke horizontal-shaft engines air filter of a kind of intake efficiency.
The purpose of this utility model is realized by such technological scheme, a kind of four-stroke horizontal-shaft engines air filter, comprise the base of upper cover, suction tude, filter core and band air-flow path, described filter core is horizontally set in the cavity that is made up of upper cover and base, one end of described filter core is connected with one end of suction tude, the other end of described suction tude is connected with base, and is communicated with air-flow path; Between described upper cover lower end surface and base upper-end surface, there is gas-entered passageway A, there is between described base and filter core gas-entered passageway B, have gas-entered passageway C between described filter core outer wall and upper cover inwall, described gas-entered passageway A, gas-entered passageway B and gas-entered passageway C form S type air inlet path.
Wherein, described filter core is cylindrical.
Owing to have employed technique scheme, the utility model has structure advantage simple, easy for installation, with low cost, adopt it can extend air inlet path, make intake efficiency higher, improve complete machine power performance, meanwhile, being horizontally disposed with of filter core, save vertical space, make structure compacter.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that air-flow of the present utility model moves towards figure.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, 2, a kind of four-stroke horizontal-shaft engines air filter, comprise the base 5 of upper cover 1, suction tude 2, filter core 3 and band air-flow path 4, described filter core 3 is horizontally set in the cavity that is made up of upper cover 1 and base 5, one end of described filter core 3 is connected with one end of suction tude 2, the other end of described suction tude 2 is connected with base 5, and is communicated with air-flow path 4; Between described upper cover 1 lower end surface and base 5 upper-end surface, there is gas-entered passageway A, between described base 5 and filter core 3, there is gas-entered passageway B, have gas-entered passageway C between described filter core 3 outer wall and upper cover 1 inwall, described gas-entered passageway A, gas-entered passageway B and gas-entered passageway C form S type air inlet path.
In order to increase path and the area of air inlet, described filter core 3 is cylindrical.
In the utility model, the S type that air is formed through gas-entered passageway A, gas-entered passageway B and gas-entered passageway C lengthens intake duct, and make air moving direction in intake duct occur repeatedly to change, when gas mixes with oil, gas-oil mixes more even, abundant; When the piston compression of motor, but time intake valve is not also closed completely, also to retain the air after the filtration more than general intake duct, speed is higher in intake duct, and continue to enter cylinder, add the air inflow of engine chamber.
