The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of canister of absorbing gasoline steam, and the absorption path of this canister to gasoline vapor is longer.
The utility model solves the technological scheme that its technical problem adopts: a kind of canister of absorbing gasoline steam, comprise the tank body that right-hand member is closed, tank body left end is provided with the cover of evagination indent, the screen matched with tank body endoporus and the first filter cloth body is provided with in tank body left end endoporus, the the second filter cloth body matched with tank body endoporus is provided with in tank body right-hand member endoporus, tank body endoporus is separated into the adsorption space in left side and the spatial transition on right side by the second filter cloth body, is filled with the granular active carbon for absorbing gasoline steam in adsorption space;
Described adsorption space is communicated with air by concave space in the first filter cloth body, screen, cover and the atmospheric air port that is arranged on cover center successively;
Described tank body closed end side is provided with the suction port for being connected with petrol tank, and described adsorption space is communicated with suction port by the second filter cloth body, spatial transition successively;
Described tank body closed end is connected with the valve gap of evagination indent, valve gap side is provided with the first air outlet for being connected with motor, tank body closed end end face center is provided with the second air outlet, second air outlet outlet end is provided with the diaphragm type one-way valve of the concave space being positioned at valve gap, and described adsorption space is communicated with the first air outlet by concave space in the second filter cloth body, spatial transition, the second air outlet, diaphragm type one-way valve and valve gap successively;
Segmental baffle is provided with in the middle part of described tank body adsorption space.
Described segmental baffle has a pair relative arc-shaped side being connected successively straight flange relative with a pair, and the arc-shaped side of segmental baffle both sides is separately fixed on tank body inner hole wall.
The beneficial effects of the utility model are: be provided with segmental baffle in endoporus of the present utility model, due to the cause of segmental baffle, the absorption path of gasoline vapor in canister endoporus entered canister endoporus from petrol tank extends to some extent, thus improves the adsorption efficiency of active carbon to it.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
