Detailed Implementation

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figures 1-4 This utility model discloses an automotive air tank with a filtering function, comprising: an air tank body 1, an air outlet 2, an air inlet 3, and two mounting rods 6 fixedly connected to the surface of the air tank body 1; an mounting frame 16 and a first filter element 4 disposed inside the air tank body 1; the mounting frame 16 being fixedly connected to the inner wall of the air tank body 1; the first filter element 4 contacting the right surface of the mounting frame 16; the first filter element 4 consisting of an openable rubber ring 10 and a first filter screen 11; the openable rubber ring 10 contacting the surface of the mounting frame 16; the first filter screen 11 being penetrated by the joint of the openable rubber ring 10; the first filter element 4 being used to directly isolate impurities entering the tank; multiple elastic strips 12 fixedly connected to the surface of the openable rubber ring 10; the elastic strips 12 being used to increase the elasticity of the openable rubber ring 10; a positioning groove 18 disposed on the left surface of the mounting frame 16; the left half of the openable rubber ring 10 being located inside the positioning groove 18; the positioning groove 18 increasing the stability of the first filter element 4 during operation.

[0023] Specifically, the two parts of the opening and closing rubber ring 10 are separated, and the first filter screen 11 is placed in the middle of the two parts. After the opening and closing rubber ring 10 is combined, the first filter screen 11 and the opening and closing rubber ring 10 are integrated to form the first filter element 4. The rubber material and the elastic strip 12 can be bent by applying external force, thereby changing the volume of the first filter element 4. At the same time, the elastic deformation characteristic enables the elastic strip 12 and the opening and closing rubber ring 10 to automatically extend and recover after the lack of external force restriction.

[0024] The inner wall of the mounting frame 16 and the upper end of the first filter element 4 are respectively fixedly connected to the second filter screen 17 and the rubber strip 5. The second filter screen 17 further restricts the transmission range of impurities in the cylinder. The rubber strip 5 is used to increase the stress point of the first filter element 4. The surface of the gas storage cylinder body 1 and the surface of the sealing plate 7 are provided with a storage groove 14. The rubber strip 5 is located inside the storage groove 14. The storage groove 14 improves the stability of the rubber strip 5.

[0025] Specifically, impurities that pass through the first filter screen 11 are further isolated by the second filter screen 17, thereby isolating the impurities in the installation area of ​​the mounting frame 16. During the process of adding the first filter element 4, the staff applies force to the first filter element 4 from the outside through the rubber strip 5 to change the position of the first filter element 4, and the exposed part of the rubber strip 5 fills the inside of the receiving groove 14, thereby preventing the rubber strip 5 from falling into the cylinder.

[0026] The surface of the air tank body 1 and the interior of the mounting rod 6 near the air inlet 3 are respectively provided with a retrieval opening 13 and a cavity 15. The cavity 15 passes through the mounting rod 6 near the air inlet 3. The retrieval opening 13 and the cavity 15 are distributed opposite to each other. When the air tank is being repaired, the first filter element 4 extends to the outside through the retrieval opening 13 and the cavity 15. The retrieval opening 13 and the cavity 15 cooperate to provide conditions for workers to replace the first filter element 4. A sealing plate 7 is provided at the upper end of the air tank body 1. Plate 7 encloses cavity 15. A rubber block 9 is fixedly connected to the right surface of plate 7. The rubber block 9 contacts the inner wall of the retrieval opening 13. The cooperation between plate 7 and rubber block 9 increases the sealing effect when the air storage cylinder body 1 is in operation. A reinforcing component 8 is provided between the surface of plate 7 and the inner wall of cavity 15. The reinforcing component 8 consists of bolts and nuts. The bolts of the reinforcing component 8 are rotatably connected to plate 7, and the nuts are fixedly connected to the right inner wall of cavity 15. The reinforcing component 8 increases the stability of plate 7 when it is in operation.

[0027] Specifically, the first filter element 4, which is bent to change its volume, enters the cylinder through the retrieval opening 13. After the first filter element 4 is no longer restricted by external force inside the cylinder, it returns to its original shape. After the first filter element 4 is added, the rubber block 9 is pressed into the retrieval opening 13 by tilting and manually pressing. In this way, the cavity 15 and the retrieval opening 13 are sealed by the sealing plate 7 and the rubber block 9. Finally, the sealing plate 7 is fixed by the reinforcing component 8.

[0028] Working principle: After the first filter screen 11 is clamped by the opening and closing rubber ring 10, the opening and closing rubber ring 10 is manually bent to ensure that the first filter element 4 passes through the retrieval opening 13 and enters the cylinder. After entering the cylinder, the elastic strip 12 and the opening and closing rubber ring 10 automatically unfold and return to their original positions. At this time, an external object such as a long rod is used to press the opening and closing rubber ring 10 into the positioning groove 18 through the retrieval opening 13. Then, the cavity 15 and the retrieval opening 13 are sealed by the sealing plate 7 and the rubber block 9. When the filter screen needs to be replaced, the sealing plate 7 is opened and the first filter element 4 can be pulled out of the cylinder through the rubber strip 5.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
