Description

Technical Field

[0001] The utility model relates to the technical field of automobile carbon canisters, in particular to an activated carbon replacement device for an automobile carbon canister. Background Art

[0002] The carbon canister is usually installed between the gasoline tank and the engine. Since gasoline is a volatile liquid, the fuel tank is often filled with vapor at room temperature. The function of the fuel evaporation emission control system is to introduce vapor into combustion and prevent it from volatilizing into the atmosphere. The activated carbon canister storage device plays an important role in this process. Because activated carbon has an adsorption function, when the car is running or turned off, the gasoline vapor in the fuel tank enters the upper part of the activated carbon canister through the pipeline, and fresh air enters the activated carbon canister from the lower part of the activated carbon canister. After the engine is turned off, the gasoline vapor and fresh air are mixed in the tank and stored in the activated carbon canister. When the engine is started, the electromagnetic valve of the fuel evaporation purification device installed between the activated carbon canister and the intake manifold opens, and the gasoline vapor in the activated carbon canister is sucked into the intake manifold to participate in combustion.

[0003] When replacing the activated carbon in the carbon canister, it is usually necessary to open the lid at the bottom of the carbon canister, take out the filter cotton and activated carbon in the canister, then fill in new columnar activated carbon and seal it with the assembled filter cotton. In the process of replacing the activated carbon in the carbon canister, this simple carbon canister structure is usually manually loaded with filter cotton and activated carbon when replacing the activated carbon, which makes it easy for the filling amount of activated carbon to be wrong under human action, thereby affecting the card-fitting and filtering effect of the filter cotton and activated carbon. This makes the manual replacement of the activated carbon in the automobile carbon canister error-prone, which is easy to affect the normal use of the automobile carbon canister. For this reason, we propose an activated carbon replacement device for an automobile carbon canister. Utility Model Content

[0004] The main purpose of the utility model is to provide an activated carbon replacement device for an automobile carbon canister, which converts the automobile carbon canister into a combined tank body composed of a bottom tank body, a tank cover and a core barrel, and the bottom tank body can be fixed at the carbon canister installation position of the automobile. When the activated carbon of the automobile carbon canister needs to be replaced after long-term use, the bottom rotating ring under the tank cover can be unscrewed from the bottom tank body, and then the carbon canister core composed of the barrel rotating ring, the core barrel, filter cotton A, filter cotton B and activated carbon can be directly taken out of the bottom tank body, and a new carbon canister core can be taken out and reinstalled in the bottom tank body, which is convenient for replacing the activated carbon inside the automobile carbon canister, and the standardized activated carbon container of the carbon canister core can ensure the replacement and installation standardization of the activated carbon and filter cotton, and ensure that the automobile carbon canister can be used normally after the activated carbon is replaced. At the same time, after the core barrel structure is set inside the automobile carbon canister, the activated carbon can cooperate with the counter-rotating barrel rotating ring to spin the filter cotton A, activated carbon and filter cotton B, so that the activated carbon can be conveniently taken out and replaced as a whole when replaced, which can effectively solve the problems in the background technology.

[0013] Furthermore, the block diameter of the filter cotton A and the filter cotton B is smaller than the ring opening diameter of the cylindrical ring;

[0014] By adopting the above technical solution, the drum rotating ring can press the filter cotton A and the filter cotton B outside the activated carbon in opposite directions in the core drum.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model changes the automobile carbon canister into a combined canister body composed of a bottom canister body, a canister cover and a core barrel, and the bottom canister body can be fixed to the carbon canister installation position of the automobile. When the activated carbon in the automobile carbon canister needs to be replaced after long-term use, the bottom rotating ring below the canister cover can be unscrewed from the bottom canister body, and then the carbon canister core composed of the core rotating ring, the core barrel, filter cotton A, filter cotton B and activated carbon can be directly taken out of the bottom canister body, and a new carbon canister core can be taken out and reinstalled in the bottom canister body, thereby facilitating the replacement of the activated carbon in the automobile carbon canister.
