Abstract
The utility model belongs to the mechanical field of internal combustion engines, and particularly relates to an air filter assembly. The air filter assembly comprises an upper cover, a case, a filter element and an air inlet pipe. An air inlet channel communicated with the interior of the case is formed in the gap between the upper cover and the case and is formed in the surface of the case in a spiral mode, the filter element is arranged inside the case, and one end of the air inlet pipe is communicated with the bottom of the case. The air filter assembly is good in filtering effect, simple in structure and convenient to use, effectively prevents large air impurities from directly entering the filter element, prolongs the service life of the filter element, improves the work efficiency of a diesel engine, saves the cost, and is convenient to disassemble and safe and reliable to use.
Description
Technical field
The utility model belongs to combustion engine mechanical field, is specially a kind of air cleaner assy.
Background technique
Existing air-strainer, intake grill is short and straight, and air plankton and dust directly rely on filter core to filter, and its filtering effect substantially only depends on filter core, the life cycle of filter core has determined the replacement frequency of air-strainer, the too high diesel engine work efficiency that affects of replacement frequency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of air cleaner assy is provided, and has extended filter core working life, has improved diesel engine work efficiency.
For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of air cleaner assy, comprise upper cover, housing, filter core and suction tude, described upper cover is communicated with the gas-entered passageway of enclosure interior with the gap location setting between housing, this gas-entered passageway arranges at surface of shell spiral, filter core is arranged at enclosure interior, and one end of suction tude is communicated with housing bottom.
And the surface of contact between described upper cover and housing arranges seal ring.
Filtering of the present utility model is effective, simple in structure, easy to use, has effectively stoped larger air plankton directly to enter filter body, thereby extends the working life of filter body, improves the working efficiency of diesel engine, cost-saving, and convenient disassembly is safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, upper cover, 2, housing, 3, filter core, 4, suction tude, 5, gas-entered passageway, 6, seal ring.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The present embodiment provides a kind of air cleaner assy, as shown in Figure 1, comprise upper cover 1, housing 2, filter core 3 and suction tude 4, described upper cover 1 is communicated with the gas-entered passageway 5 of housing 2 inside with the gap location setting between housing 2, this gas-entered passageway 5 is in the surperficial spiral setting of housing 2, filter core 3 is arranged at housing 2 inside, and one end of suction tude 4 is communicated with housing 2 bottoms.
Further, the surface of contact between above-mentioned upper cover 1 and housing 2 arranges seal ring 6.
The utility model air enters housing 2 by the octal gas-entered passageway 5 on housing 2, then along housing 2 inner sides or outside spiral rotating, makes thicker impurity and dust obtain entering the primary filter before filter core 3, and air enters internal-combustion engine after purifying finally by filter core 3.Spiral air intake passage can reduce airborne dust and enter filter cleaner, can extend the working life of housing 2 inner filter cores 3.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement or distortion, these improvement or distortion also should be considered as protection domain of the present utility model.
Claims (2)
1. an air cleaner assy, comprise upper cover, housing, filter core and suction tude, it is characterized in that: described upper cover is communicated with the gas-entered passageway of enclosure interior with the gap location setting between housing, this gas-entered passageway arranges at surface of shell spiral, filter core is arranged at enclosure interior, and one end of suction tude is communicated with housing bottom.
