Description
Technical field
The utility model relates to automobile manufacturing field, in particular to a kind of canister.
Background technique
Canister is generally seated between petrol tank and engine.Since gasoline is a kind of volatile liquid, fire at normal temperature
Fuel tank is often fill with steam, and the effect of evaporative fuel emission control device is that steam introducing motor intake manifold is burnt and prevented
It only evaporate into atmosphere, what this process played an important role is canister.
Such as the Chinese patent disclosure of Publication No. CN107076063A, it discloses a kind of canister, including shell, set
The first Room and second Room inside housings are set, the first indoor first adsorbent is filled in and is filled in second indoor
Two adsorbents further include that the evaporated fuel being connected with enclosure interior imports port, removes port and atmosphere opening port, gasoline
When evaporation from evaporated fuel import port enter enclosure interior, by the first Room and second Room during can by first absorption
Agent and the absorption of the second adsorbent are fallen, and the gas by absorption is discharged to the outside in air from atmosphere opening port.
In the prior art, if canister is mounted on crankcase in the following, crankcase has certain arc close to the surface of canister
Degree, it is generally the case that the surface of canister is plane, cannot make full use of installation space.
Utility model content
The purpose of the utility model is to provide a kind of canisters, its advantage is that the installation space utilization rate of canister can be improved.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of canister, including shell
Body, the bottom cover for being fixedly connected on shell one end and the adsorption orifice being arranged on shell, desorption mouth and atmospheric air port, wherein bottom cover
It is closed with shell phase sealing cover, for enclosure interior space to be connected with fuel tank, desorption mouth is used for enclosure interior sky adsorption orifice
Between be connected with engine, atmospheric air port is for enclosure interior space to be connected with atmosphere, and enclosure interior is equipped with for adsorbing vapour
The adsorbent material of oil vapour, the upper surface of the shell are towards the curved cambered surface in direction far from shell.
Through the above technical solutions, canister is mounted on crankcase in the following, crankcase has centainly close to the surface of canister
Radian, canister upper surface is bent upwards can closely abut with the lower surface of crankcase, make full use of the installation below crankcase
Space increases the volume of canister inner space, can store more adsorbent materials, improve the adsorption desorption performance of canister.
The utility model is further arranged to: being fixedly connected with partition in the inner walls.
The utility model is further arranged to: the center of the adsorption orifice, desorption mouth and atmospheric air port is generally aligned in the same plane
On.
The utility model is further arranged to: the adsorbent material is active powdered carbon.
The utility model is further arranged to: fixed block is fixedly connected on the bottom cover, bottom cover passes through fixed block and vapour
Vehicle is fixedly connected.
The utility model is further arranged to: enclosure interior space is divided into two cavitys, two cavitys by the partition
It is connected in one end close to bottom cover.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: canister, as shown in Figure 1, include shell 1 and be fixedly connected on the bottom cover 2 of 1 one end of shell, in conjunction with Fig. 2,
It is hollow structure inside shell 1, bottom cover 2 is for being sealed shell 1.Shell 1 is equipped with adsorption orifice far from one end of bottom cover 2
11, mouth 12 and atmospheric air port 13 is desorbed, the center of adsorption orifice 11, desorption mouth 12 and atmospheric air port 13 is in the same plane, wherein
For 1 inner space of shell to be connected with fuel tank, desorption mouth 12 is used for 1 inner space of shell and engine phase adsorption orifice 11
Connection, atmospheric air port 13 is for 1 inner space of shell to be connected with atmosphere；1 inside filling adsorption material of shell (is not drawn in figure
Out), adsorbent material can be active carbon powder, and active powdered carbon has stronger adsorption desorption ability to gasoline vapor.Vapour in fuel tank
Gasoline vapor is formed after oil volatilization and is entered inside shell 1 from adsorption orifice 11, is in contact with adsorbent material, adsorbent material is to gasoline
Steam is adsorbed；1 inner wall of shell is fixedly connected with partition 3, and 1 inner space of shell is divided into two cavitys by partition 3, and two
Cavity is connected close to one end of bottom cover 2, and adsorption orifice 11 and atmospheric air port 13 are located at the two sides of partition 3, gasoline vapor from
