Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive charcoal canister technology, specifically to a charcoal rod structure that is easy to install. Background Technology
[0002] The charcoal canister is typically located between the fuel 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 this vapor into combustion and prevent it from evaporating into the atmosphere. The activated carbon canister storage device plays a crucial role in this process because activated carbon has adsorption capabilities. When the car is off and stationary, gasoline vapor from the fuel tank enters the activated carbon canister through pipes and is adsorbed by the activated carbon. When the car is running, fresh air enters through the air inlet of the activated carbon canister, carrying the gasoline vapor inside into the engine for combustion. The charcoal rod chamber is a device in the charcoal canister, besides the canister itself, that stores charcoal powder. The charcoal canister's ability to adsorb gasoline vapor is related to the amount of charcoal powder stored in it, the storage method of the charcoal powder, and the type of charcoal powder.
[0003] The current structure of the charcoal canister and charcoal rods is such that the charcoal rods are stored directly inside the charcoal rod cavity without effective cushioning and fixation. During vehicle operation, this can easily cause friction between the charcoal rods, thereby damaging them and affecting the service life of the entire charcoal canister. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a carbon rod structure that is easy to install. Its structure is simple and easy and quick to install, which solves the wear problem caused by friction of carbon rods during vehicle operation and extends the service life of the entire carbon canister.
[0005] To solve the above problems, the present invention adopts the following technical solution:
[0006] A charcoal rod structure that is easy to install includes a charcoal rod and a charcoal canister, wherein the charcoal rod is built into the charcoal canister, and a sponge sleeve is placed between the charcoal rod and the charcoal canister, and the sponge sleeve is provided with notches.
[0007] A further technical solution is that the sponge sleeve has two or more notches distributed in a ring along its surface, or there may be three or more notches, to facilitate the insertion of the carbon rod into the sponge sleeve.
[0008] A further technical solution is that the bottom of the sponge sleeve has a closed structure, which makes it easy for the sponge sleeve to be placed into the bottom of the charcoal can to limit the charcoal rod, while the charcoal rod will not contact the bottom of the charcoal can, thus playing a cushioning role.
[0009] A further technical solution is that the bottom of the charcoal canister is also provided with vents for gas to enter and exit.
[0010] The beneficial effects of this utility model are:
[0011] This utility model discloses a carbon rod structure that is easy to install. The sponge sleeve can quickly wrap the carbon rod and quickly insert it into the carbon canister for relative fixation, thereby avoiding wear of the carbon rod caused by its movement inside the carbon canister. The sponge sleeve also has notches distributed on it and does not completely wrap the carbon rod, which not only allows the carbon rod to be quickly inserted into the sponge sleeve, but also reduces the cost of the sponge sleeve. Attached Figure Description
[0012] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the accompanying drawings required for the work described in the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] The preferred embodiments of this utility model will be described in detail below so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of this utility model.
[0018] See Figures 1 to 3 As shown, an easy-to-install charcoal rod structure includes a charcoal rod 1 and a charcoal canister 2. The charcoal rod 1 is built into the charcoal canister 2, and a sponge sleeve 3 is placed between the charcoal rod 1 and the charcoal canister 2. The sponge sleeve 3 also has notches 5 distributed on it.
[0019] The sponge sleeve 3 has two or more notches 5 arranged in a ring along its upper edge, or three or more notches 5, to facilitate the insertion of the carbon rod 1 into the sponge sleeve 3. The bottom of the sponge sleeve 3 has a closed structure, which allows the sponge sleeve 3 to be inserted into the bottom of the carbon canister 2 to limit the carbon rod 1, while preventing the carbon rod 1 from contacting the bottom of the carbon canister 2, thus providing a cushioning effect. The bottom of the carbon canister 2 also has vents 4 for gas to enter and exit.
[0020] In this embodiment, the carbon rod 1 is first inserted into the sponge sleeve 3. Because there are notches 5 distributed on the sponge sleeve 3, the upper part of the sponge sleeve 3 can be stretched outward when the carbon rod 1 is inserted, so that the carbon rod 1 is inserted more smoothly. Then the sponge sleeve 3 together with the carbon rod 1 is inserted into the carbon canister 2.
[0021] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that are conceived without creative effort should be covered by the protection scope of this utility model.
