[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] A carbon canister with a four-chamber toner structure, such as Figs. 1 to 4 As shown, the housing includes an outer shell 1, which includes an upper cover 11, an end cover 12, a housing 13, and a bottom cover 14. The upper cover 11 and the end cover 12 are both disposed on the upper surface of the housing 13, and the bottom cover 14 is sealed on the lower surface of the housing 13.

[0021] The outer shell 1 is provided with an atmospheric port 2, an adsorption port 3 and a desorption port 4. Specifically, the atmospheric port 2, the adsorption port 3 and the desorption port 4 are separated and arranged on the upper cover 11. That is, when the oil and gas pass through the upper cover 11, they respectively go to the atmospheric port 2, the adsorption port 3 and the desorption port 4 through their respective independent channels.

[0022] The outer shell 1 is provided with four accommodating cavities. Specifically, the outer shell 13 is provided with two cross-shaped partitions 15, which divide the outer shell 13 to form four accommodating cavities. In this embodiment, the four accommodating cavities include accommodating cavity 18, accommodating cavity 29, accommodating cavity 30, and accommodating cavity 41.

[0023] Adsorption port 3 and desorption port 4 are connected to the same receiving cavity. Specifically, in this embodiment, receiving cavity 18 corresponds to adsorption port 3 and desorption port 4, that is, both adsorption port 3 and desorption port 4 are connected to receiving cavity 18.

[0024] A partition section 17 is provided in the middle of the receiving cavity 18. The partition section 17 divides the receiving cavity 18 into two parts corresponding to the adsorption port 3 and the desorption port 4 respectively. It should be noted that, through the partition section 17, a part of the receiving cavity 18 is divided into two independent areas, which correspond to the adsorption port 3 and the desorption port 4 respectively. When the oil and gas pass through the receiving cavity 18, they will go to the adsorption port 3 and the desorption port 4 respectively along the independent areas.

[0025] The atmospheric port 2 is connected to another receiving cavity. Specifically, in this embodiment, the receiving cavity 21 corresponds to the atmospheric port 2, that is, the atmospheric port 2 is connected to the receiving cavity 21.

[0026] The end cover 12 is in communication with two containing cavities, specifically, in the embodiment, the end cover 12 is in communication with the containing cavity two 19 and the containing cavity three 20.

[0027] When the desorption port 4 is closed, the oil gas in the oil tank enters from the adsorption port 3 and flows through the four containing cavities in turn and then flows out from the atmosphere port 2, specifically, the oil gas in the oil tank flows to the containing cavity two 19 after entering the containing cavity one 18 from the adsorption port 3, and then flows to the containing cavity three 20 through the end cover 12, and then flows to the containing cavity four 21 and flows out from the atmosphere port 2.

[0028] The four containing cavities are sequentially provided with non-woven fabric 6, carbon powder 7, sponge 8, partition plate 9 and spring 10, further, each containing cavity is provided with a limiting step 16 for limiting the non-woven fabric 6, so as to ensure the stable installation position of the non-woven fabric 6 in the containing cavity, the sponge 8 cooperates with the non-woven fabric 6 to limit the carbon powder 7, so as to limit the carbon powder 7 in a specific area of the containing cavity, prevent the carbon powder 7 from being scattered or lost during the flow of oil gas, and ensure the uniform distribution of the carbon powder 7 in the containing cavity, so that the oil gas can fully contact with the carbon powder 7, and the ability of the carbon powder 7 to adsorb harmful substances and odor molecules in the oil gas can be fully utilized.

[0029] The partition plate 9 supports the sponge 8, specifically, the upper surface of the partition plate 9 abuts against the lower surface of the sponge 8, through the supporting action of the partition plate 9 on the sponge 8, the position of the sponge 8 can be ensured stable, and then the limiting action of the sponge 8 on the carbon powder 7 can be ensured, and the sponge 8 can be ensured not to be deformed or collapsed under the action of the oil gas pressure and its own weight.

[0030] The spring 10 supports the partition plate 9, specifically, one end of the spring 10 abuts against or is connected with the bottom cover 14, and the other end of the spring 10 abuts against or is connected with the partition plate 9, through the supporting action of the spring 10, the stability of the non-woven fabric 6, the carbon powder 7, the sponge 8 and the partition plate 9 can be effectively ensured when the oil gas passes through the containing cavity.

[0031] The containing cavity one 18 and the containing cavity four 21 are both provided with a plurality of support protrusions 5 for supporting the non-woven fabric 6, it should be noted that due to the concave bottom of the containing cavity one 18 and the concave bottom of the containing cavity four 21, the middle part of the non-woven fabric 6 cannot be stably supported, therefore, a plurality of support protrusions 5 are arranged to stably support the middle part of the non-woven fabric 6, so as to avoid the deformation of the non-woven fabric 6, and make the non-woven fabric 6 always maintain a good shape.

[0032] It should be noted that the non-woven fabric 6 in the containing cavity one 18 is divided into two parts corresponding to the adsorption port 3 and the desorption port 4.

[0033] It should be noted that by setting four accommodating cavities and the oil and gas sequentially passing through the four accommodating cavities, the impurities, harmful substances and odor molecules in the oil and gas can be fully intercepted and adsorbed by the non-woven fabric 6, the carbon powder 7 and the sponge 8 in each accommodating cavity, thereby improving the effect of oil and gas treatment, and after filtration, the oil and gas is discharged from the atmosphere port 2, reducing the pollution caused by oil and gas emission.

[0034] It should be further explained that since the four accommodating cavities are all provided with carbon powder 7, the oil and gas will fully contact the carbon powder 7 when passing through the four accommodating cavities, which can significantly prolong the flow distance of the airflow, thereby greatly increasing the contact time of the oil and gas with the carbon powder 7, so that the carbon powder 7 in each accommodating cavity can fully participate in the adsorption process, thereby effectively improving the utilization rate of the carbon powder 7, and further optimizing the treatment performance of the carbon tank for oil and gas.

[0035] The specific embodiments described herein are merely illustrative of the present application; those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
