Description

Technical Field

[0001] The utility model relates to the technical field of vehicle ash filters, in particular to a portable ash filter. Background Art

[0002] Ash filter is a dust filter, which is a device that matches the carbon canister and is installed at the end of the pipe leading to the atmosphere of the carbon canister. Due to the influence of the environment, it is easy to be blocked by dust and other impurities, which will shorten the effective service life of the carbon canister. However, after installing the ash filter, it can help the carbon canister to block dust, dirt and other impurities, avoid clogging the ventilation pipe of the carbon canister, and can also protect the OBD detection valve (ie CVS valve, DMTL, etc.), so as to extend the effective service life of the carbon canister. Ash filter can be divided into coarse filtration and fine filtration according to its own filtering effect. The accuracy requirements of these two types of dust and impurity filtration are different. However, the installation method of ash filter on the market is relatively simple, and it is generally connected to the carbon canister through a pipeline. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a portable ash filter, which has a simple structure, reduces costs and improves portability of installation.

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] A portable ash filter comprises an outer shell, a bottom plate and a filter element. The bottom plate is relatively fixed to the bottom end side of the outer shell, the filter element is built in the outer shell, partitions are evenly fixed along the circumference on the inner side of the top end of the outer shell, and jacks are distributed on the bottom plate.

[0006] A further technical solution is that elastic rods extending upward are distributed along the circumference of the bottom plate, and gaps are provided between the two elastic rods. The gaps allow the elastic rods to bend up and down, and the elastic rods arranged circumferentially form an insertion hole. When the charcoal canister air pipe together with the annular ring arranged on the outer circumference of the charcoal canister air pipe extend into the outer shell, the elastic rods are squeezed and deformed by the charcoal canister air pipe together with the annular ring and stretched outward. When the annular ring enters the upper end of the elastic rod, the elastic rod returns to its position with its top supporting the annular ring on the charcoal canister air pipe, preventing the charcoal canister air pipe from moving out of the bottom plate.

[0007] A further technical solution is that a limiting sleeve is fixed on the inner side of the partition. The function of the limiting sleeve is that when the carbon canister air pipe extends into the outer shell, it can enter the limiting sleeve to prevent the carbon canister air pipe from swinging. Of course, the same effect can be achieved without the limiting sleeve through the partition.

[0008] A further technical solution is that the bottom plate is fixed to the bottom end side of the outer shell by snapping, threading or bonding. The bottom plate can be connected to the bottom end side of the outer shell in different ways, not limited to snapping, threading or bonding, but can also be other connection methods.

[0009] A further technical solution is that buckle parts are distributed along the circumference of the bottom end of the outer shell, and slots are provided between the buckle parts. The slots can cause the buckle parts to deform slightly so that the bottom plate can be easily buckled and fixed to the outer shell.

[0010] A further technical solution is that top blocks are distributed along the circumference of the upper surface of the bottom plate, so that the filter element is supported on the upper end of the top block, so that there is a certain distance between the filter element and the bottom plate, and the air filtered by the filter element is first gathered within this distance and then discharged, which is more convenient for gas circulation. At the same time, the filter element generally adopts a cylindrical structure, which is more convenient to install in the outer shell and will not be squeezed and deformed to affect the filtering effect.

[0011] The beneficial effects of the utility model are as follows: the utility model is a portable ash filter, in which the ash filter and the charcoal canister are integrated into one, and the installation method is convenient and quick with just one plug, reducing the connection method of three parties such as pipelines, and has a certain convenience in the arrangement of the whole vehicle, reducing the cost to a certain extent. In addition, the ash filter can also be flexibly made into a coarse filter or a fine filter according to the needs, thereby increasing the selectivity of the ash filter type.

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0019] See also Figures 1 to 4 As shown, a portable ash filter includes an outer shell 1, a bottom plate 6 and a filter element 5. The bottom plate 6 is relatively fixed to the bottom end side of the outer shell 1, and the filter element 5 is built into the outer shell 1. A partition plate 2 is evenly fixed along the circumference on the inner side of the top end of the outer shell 1, and jacks 12 are distributed on the bottom plate 6.

[0020] The bottom plate 6 is provided with elastic rods 11 extending upward along the circumference, and there are gaps 13 between the two elastic rods 11. The gaps 13 allow the elastic rods 11 to bend up and down, and the elastic rods 11 arranged on the circumference are combined to form a plug hole 12. When the carbon canister air pipe 4 together with the annular ring 7 arranged on the outer circumference of the carbon canister air pipe 4 extend into the outer shell 1, the elastic rods 11 are squeezed and deformed by the carbon canister air pipe 4 together with the annular ring 7 and are stretched outward. When the annular ring 7 enters the upper end of the elastic rods 11, the elastic rods 11 return to their tops to support the annular ring 7 on the carbon canister air pipe 4, preventing the carbon canister air pipe 4 from moving out of the bottom plate 6. A limiting sleeve 3 is also fixed on the inner side of the partition 2. The function of the limiting sleeve 3 is that when the carbon canister air pipe 4 extends into the outer shell 1, it can enter the limiting sleeve 3 to prevent the carbon canister air pipe 4 from swinging. Of course, the same effect can be achieved without the limiting sleeve 3 through the partition 2. The bottom plate 6 is fixed to the bottom side of the outer shell 1 by snap-fitting, threading or adhesion. The bottom plate 6 can be connected to the bottom side of the outer shell 1 in different ways, not limited to snap-fitting, threading or adhesion, but can also be other connection methods. There are snap-fitting parts 8 distributed along the circumference of the bottom end of the outer shell 1, and there are notches 9 between the snap-fitting parts 8. The notches 9 can make the snap-fitting parts 8 slightly deformed so that the bottom plate 6 can be easily snap-fitted and fixed to the outer shell 1. There are also top blocks 10 distributed along the circumference of the upper end surface of the bottom plate 6, so that the filter element 5 is supported on the upper end of the top block 10, so that there is a certain distance between the filter element 5 and the bottom plate 6. The air filtered by the filter element 5 is first gathered and then discharged within this distance, which is more convenient for gas circulation. At the same time, the filter element 5 generally adopts a cylindrical structure, which is more convenient to install in the outer shell 1, and will not be squeezed and deformed to affect the filtering effect.

[0021] In this embodiment, the filter element 5 is first inserted into the inner side of the outer shell 1, and then the bottom plate 6 is buckled onto the bottom end side of the outer shell 1, and finally the carbon canister air pipe 4 passes through the insertion hole 12 on the bottom plate 6 and is inserted into the inner side of the outer shell 1, and the top end of the carbon canister air pipe 4 is located inside the limiting sleeve 3 to limit its shaking. When the carbon canister air pipe 4 is inserted into the outer shell 1 and is in place, as shown in FIG. Figure 1As shown, the annular ring 7 on the charcoal canister air pipe 4 can be snapped into the position between the top end side of the upwardly bent extension of the elastic rod 11 and the bottom end side of the limiting sleeve 3, so that it is integrated with the charcoal canister air pipe 4 into an integrated structure, and the installation is more convenient and quick. The charcoal canister air pipe 4 can be relatively fixed by just plugging it in. During filtering, the top port of the charcoal canister air pipe 4 is used to discharge gas, and the gas is discharged from the top end of the limiting sleeve 3. After being discharged, the gas flows downward from the position of the partition 2 between the outer shell 1 and the limiting sleeve 3, and then is filtered by the filter element 5, and finally is discharged from the gap 13 of the bottom plate 6.

[0022] The entire ash filter can also be flexibly made into a coarse filter or a fine filter according to needs, thereby increasing the selectivity of the ash filter type. The difference between the coarse filter and the fine filter is the replacement of the filter element 5 inside the outer shell 1. The coarse filter can be a sponge or other coarse filter material, and the fine filter can be a filter paper or other fine filter material. Of course, it can also be the upper coarse filter material and the lower fine filter material inside the outer shell 1, or the upper fine filter material and the lower coarse filter material. The outer shell 1 is a raised structure, which is convenient for the distribution of the partition 2. Of course, it can also be a whole cylindrical structure, and the partition 2 can be widened.

[0023] The above embodiment is only an example of the present invention and is not intended to limit the implementation and scope of rights of the present invention. Any technical solution that is identical or equivalent to the content described in the claims of the present invention should be included in the protection scope of the present invention.
