Description
Technical field
The utility model is related to auto parts machinery field, more particularly to automobile canister structure.
Background technology
Canister is in fact to be under the jurisdiction of gasoline evaporation control system（EVAP）A part, the system is in order to avoid engine
Fuel-steam escapes into air and is introduced into after shutting down, and from nineteen ninety-five, China specifies that all new automobiles for dispatching from the factory are necessary
Possesses this system.First, we look at its operation principle, and after engine misses, gasoline vapor is with fresh air in tank
Mix and be stored in activated carbon canister, after engine start, the electromagnetic valve between activated carbon canister and inlet manifold is beaten
Open, the gasoline vapor in activated carbon canister is brought into by pure air under the vacuum effect of air inlet pipe and burning is participated in cylinder.This
Sample does and not only reduce discharge, and also reduces oil consumption.
The patent document of application number 201320434188.1 discloses a kind of canister, mainly includes that a tubular shell, one consolidate
It is scheduled on the lower cover of housing bottom；One is formed between the housing and lower cover is used to fill the inner chamber of activated carbon, and in the inner chamber also
It is provided with a baffle plate；Also include adsorption orifice, desorption mouth and atmosphere entry, wherein adsorption orifice and desorption mouth is arranged on the top of housing
End, atmosphere entry is arranged on the lower lid of housing bottom；The lower cover middle concave part is described logical big into a funnelform cavity
Gas port is connected with the cavity；Atmosphere entry is arranged on housing bottom, separating two ends with adsorption orifice, desorption mouth is set.
Tank base and housing connection are the edges that housing is blocked by tank base edge, the connection side of only single button
Formula easily causes that both connection gaps are leaked out and is easily broken off at oil gas, and housing buckle.
Utility model content
The purpose of this utility model is to provide a kind of automobile canister structure, and housing and closing cap are sealed using multilayer dentation
Circle mutual cooperation is fixed and seals, and improves the sealing of canister and the service life of canister.
Above-mentioned purpose of the present utility model technical scheme is that：A kind of automobile canister structure, bag
Housing is included, case top is enclosed construction, and case top is provided with adsorption tube and desorption pipe, and housing bottom is opening shape,
Also include closing cap, closing cap bottom is additionally provided with downwardly convex cavity, cavity is provided with ventilation duct, the closing cap company of being provided with upwards
Flange is connect, flange is provided with some dentation sealing rings that Open Side Down, and inner walls are provided with the dentation sealing ring of opening upwards,
The dentation sealing ring of opening upwards is identical with the dentation sealing ring quantity of opening upwards, and housing and closing cap pass through what Open Side Down
The dentation sealing ring reality of the dentation sealing ring of the dentation sealing ring and opening upwards dentation sealing ring that Open Side Down and opening upwards
Now seal, closing is covered with screen pack.
By using above-mentioned technical proposal, for placing activated carbon in the housing of canister.The adsorption tube and fuel tank of canister lead to
Flexible pipe connection is crossed, desorption pipe is connected by the manifold of magnetic valve and flexible pipe and engine.If being set on the side wall of the bottom of housing
The dentation sealing ring of dry opening upwards, housing is furnished with closing cap, sets flange on closing cap, flange equally set it is some be open to
Under dentation sealing ring, the dentation sealing ring that Open Side Down is identical with the dentation sealing ring quantity of opening upwards.Closing cap it is convex
