Abstract
The utility model relates to the field of fuel systems, in particular to a filtering device. A shell body is sleeved on an outer tube wall of an atmosphere venting port of a carbon tank, and filtering cotton is arranged in the shell body. The atmosphere venting port is communicated with the atmosphere through the filtering cotton in the shell body. Due to the fact that the filtering cotton is arranged in the filtering device, muddy water and dust are effectively prevented from entering into the carbon tank from the atmosphere venting port.
Description
Technical field
The utility model relates to the oil-fired system field, particularly a kind of filtrating equipment.
Background technique
The logical atmosphere port substantial section of canister on the preceding domestic vehicle adopts the simple structure of dust plug, and canister directly communicates with atmosphere.If it is not good that the canister mounting point is chosen, when working under logical atmosphere port is in very rugged environment for a long time, muddy water and dust are easy to enter canister from logical atmosphere port, cause the canister aeration resistance to increase, and the canister ventilatory function lost efficacy.
The model utility content
The purpose of this utility model is to provide a kind of filtrating equipment, guarantees that the canister ventilatory function is normal.
For reaching above effect, the technical solution adopted in the utility model is: a kind of filtrating equipment, be arranged with housing at the logical atmosphere port outer tube wall of canister, and be provided with filter cotton in the housing, described logical atmosphere port communicates with atmosphere by the filter cotton in the housing.
Compared with prior art, there is following technique effect in the utility model:
This filtrating equipment is provided with filter cotton, prevents that effectively muddy water and dust from entering canister from logical atmosphere port.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is perspective view of the present utility model.
Embodiment
Below in conjunction with Fig. 1 to Fig. 2, the utility model done being described in further detail:
Consult Fig. 1, a kind of filtrating equipment is provided with housing 10 at logical atmosphere port 51 pipe ends of canister 50, is provided with filter cotton 40 in the housing 10, and described logical atmosphere port 51 communicates with atmosphere by the filter cotton 40 in the housing 10.Owing to be provided with filter cotton 40, can effectively avoid muddy water and dust to enter canister 50 from logical atmosphere port 51.
Consult Fig. 2, described housing 10 is the pipe shape of both ends open, and housing 10 covers 20 away from an end setting of logical atmosphere port 51, and the capping 21 of lid 20 is provided with some through holes 211.Described housing 10 arranges and covers an end of 20 and be provided with thread section 11, and lid 20 passes through screw threads for fastening with housing 10.Be provided with and cover after 20, be convenient for changing the filter cotton 40 in the housing 10.
In order to protect filter cotton 40, to play a supporting role, housing 10 itself has certain degree of hardness, connects for convenience, guarantees sealing, between the logical atmosphere port 51 of described housing 10 and canister 50 rubber sleeve 30 is set.Described rubber sleeve 30 is the body that comprises large and small two sections outer tube diameters, the pipe shaft of its tubule footpath section 31 is inserted in the tube chamber of filter cotton 40 of tubbiness, the bucket bottom of filter cotton 40 is positioned at covers 20 places, one side, on the periphery wall of the big caliber section 32 of rubber sleeve 30 locating bump 33 is set, the positioning hole 12 that arranges in the radially elastic displacement setting of locating bump 33, locating bump 33 and housing 10 ends cooperates.The external diameter of the big caliber section 32 of the internal diameter of described housing 10 and filter cotton 40 and rubber sleeve 30 coincide, the outer tube diameter of the tubule footpath section 31 of rubber sleeve 30 and the lumen diameter of filter cotton 40 coincide, one end of filter cotton 40 is fitted with lid 20, and the other end of filter cotton 40 is resisted against on large and small pipeline section 32,31 the reducing step surface 34.Described large and small pipeline section 32,31 bore unanimity, big caliber section 32 is set on logical atmosphere port 51 pipe shafts of canister 50 by interference fit.
Under the normal state, locating bump 33 is upspring, and match and reach the effect that separates with housing 10 of restriction rubber sleeve 30 with positioning hole 12 on the housing 10, when needs dismounting and change part, press locating bump 33, locating bump 33 is mobile or contraction among a small circle radially, rubber sleeve 30 can be taken out from housing 10.
