As shown in fig. 2, the outer cylinder assembly 2 includes a cylinder ring 21, a seal member 22, a rear flange 23, and a fixing member 24. The cartridge 21 is a cylindrical member, which is a cartridge side wall portion in the outer cartridge assembly 2. The rear flange 23 has a generally disc-like main body shape, which is a cylindrical bottom portion in the outer cylindrical member 2. The rear flange 23 can be spliced to the bottom end of the drum ring 21 so as to form a drum structure with a feed opening together with the drum ring 21. Specifically, the rim of the bottom end of the cartridge ring 21 extends radially outward with a ring-shaped flange 211, and the outward flange 211 can serve as a mounting end for abutting connection of the rear flange 23. The sealing member 22 is provided at a mounting gap position between the rear flange 23 and the flange 211. The sealing member 22 includes a ring-shaped mounting groove 221 and a sealing structure 222 connected to the mounting groove 221. The mounting groove 221 is snap-fitted to the outer edge of the rear flange 23, and the sealing member 22 is fixed to the rear flange 23 so as to be wrapped around the outer edge of the rear flange 23. The sealing structure 222 is disposed on one side of the mounting groove 221 near the flange 211, so that the rear flange 23 can abut against the flange 211 through the sealing structure 222, thereby enabling the deformed sealing structure 222 to fill and seal the mounting gap between the rear flange 23 and the flange 211 by pressing the sealing structure 222. The fixing member 24 is provided on a side of the rear flange 23 facing away from the barrel ring 21 (i.e., a rear side of the rear flange 23 mentioned in the claims).

Wherein the sealing structure 222 is internally provided with a hollow structure 223. When the sealing structure 222 is compressed, the sealing structure 222 and the hollow structure 223 inside it are deformed. The hollow structure 223 enables the shape of the deformed sealing structure 222 to be more consistent with the shape of the installation gap between the flanging 211 and the rear flange 23, and is helpful for promoting the sealing structure 222 to be fully deformed and fill the installation gap, so that the sealing structure 222 can be more suitable for the actual shapes of different areas of the whole installation gap, the adverse effect caused by the sealing of the cylinder bottom due to the processing error of the rear flange 23 or the flanging 211 is eliminated, and the sealing effect of the bottom of the outer cylinder is better.
By arranging the mounting groove 221 on the sealing member 22, on one hand, the sealing member 22 and the rear flange 23 can be in covering and clamping connection, tight connection between the sealing member 22 and the rear flange 23 is ensured, and the sealing reliability between the sealing member 22 and the rear flange 23 is ensured. On the other hand, the sealing member 22 can be preassembled on the rear flange 23 before assembly, positioning work of the sealing member 22 in an area to be sealed is completed, the sealing member 22 is effectively prevented from being displaced or falling in the assembly process, the sealing position is better and accurate, and assembly operation of an installer is more convenient. By providing the hollow structure 223 in the sealing structure 222, the deformability of the sealing structure 222 can be improved without reducing the softness of the sealing member 22, so that the sealing structure 222 can be fully filled in the installation gap, and can have a certain hardness and a strong ability to recover deformation to maintain a sealing state, and the sealing ability is excellent.
In one possible embodiment, the edge of the rear flange 23 extends in the axial direction toward the cartridge ring 21, the notch of the mounting groove 221 faces the rear flange 23, and the groove bottom is connected with the sealing structure 222. The edge of the rear flange 23 is fastened to the flange 211 and fixed by the fixing member 24, so that the rear flange 23 extrudes and tightly supports the sealing member 22 to the flange 211, and the sealing assembly between the cylinder ring 21 and the rear flange 23 is realized.
As shown in fig. 2 to 4, in a preferred embodiment, the outer edge of the rear flange 23 is provided with a bending structure 231 along the radial outside, and the bending structure 231 turns the outer edge of the rear flange 23 outwards so as to make the extending direction of the edge of the rear flange 23 close to the extending direction of the flange 211 of the bobbin 21, thereby making the fitting degree between the flange 211 and the outer edge of the rear flange 23 higher. The mounting groove 221 is snapped to the outer edge of the rear flange 23 by the above-mentioned bending structure 231. The sealing structure 222 is connected to a side wall of the mounting groove 221 on a side near the flange 211. In the case of the cartridge ring 21 oriented horizontally with its bottom end facing rearward, as shown in the orientation of fig. 4, the outer edge of the disc-shaped body of the rear flange 23 extends axially rearward and then radially outward, thereby forming a bent structure 231 at the edge of the outer edge. At this time, the bending angle of the bending structure 231 is approximately 90 degrees. The mounting groove 221 is radially wrapped around the bent structure 231, and the sealing structure 222 is located at the front side of the front groove wall of the mounting groove 221. In an assembled state, the fixing member 24 is coupled to the flange 211 at the rear side of the rear flange 23 so as to tighten the rear flange 23 onto the flange 211, and at the same time, the rear flange 23 presses the bending structure 231 against the sealing structure 222, so that the gap between the bending structure 231 and the flange 211 is sealed.
In the above embodiment, it should be noted that the folding angles of the turned edge 211 and the bent structure 231 are not limited to the above example, and the angles may be specifically set according to the extending direction of the turned edge 211 or the bent structure 231 and the design requirement. In addition, although the above-mentioned bending structure 231 is formed by extending the outer edge of the rear flange 23 backward in the axial direction and then outward in the radial direction, it is not limited thereto. For example, the bending structure 231 may also be formed by extending the outer edge of the rear flange 23 forward along the axial direction and then outward along the radial direction, as long as the bending structure 231 can meet the installation requirement of the installation groove 221 and the abutting requirement of the bending structure 231 and the turned edge 211.

In addition, the folded edge of the bending structure 231 can cause the pressing effect of the belt-shaped extrusion ring on the sealing structure 222, and the extrusion range of the sealing structure 222 is larger, so that the deformation degree and the deformation range of the sealing structure 222 are larger, and the sealing effect is better.
Further, the side wall of the mounting groove 221 on the side away from the flange 211 is in abutting fit with the fixing member 24, so that the fixing member 24 can indirectly press the sealing member 22 by pressing the rear flange 23, and can also directly press the sealing member 22 to deform, and the groove walls on the two sides of the mounting groove 221 can be reliably covered on the outer edge of the rear flange 23.
Further, the inner side of the fixing member 24 is provided with a receiving groove 241, and the receiving groove 241 can receive the sealing member 22 to isolate the sealing member 22 from the environment inside the case 1. Specifically, the receiving groove 241 is circumferentially arranged along the sealing direction, and in the mounted state, the bent structure 231 and the sealing member 22 are both received in the receiving groove 241. According to the orientation of fig. 4, the right groove wall side of the mounting groove 221 wraps the outside of the bending structure 231 and is in close contact with the groove bottom of the receiving groove 241, so that the fixing member 24 can press the right groove wall of the mounting groove 221 onto the bending structure 231 and indirectly cause the bending structure 231 to press the sealing structure 222.
Through the arrangement, the sealing component 22 can be respectively in close contact with the flanging 211 and the bending structure 231, and the sealing reliability of the bottom of the outer cylinder is ensured. And the sealing member 22 isolated from the internal environment of the case 1 can also reduce the efficiency of corrosion, retard the aging rate of the sealing member 22, and enhance the durability of the sealing member 22.
As a specific embodiment, an inner groove wall (i.e., a groove wall on a side close to the center of the fixing member 24, a lower groove wall in fig. 4) of the receiving groove 241 is extended in the circumferential direction, so that the rear flange 23 can be located in the receiving groove 241 at a position close to the outer edge. The inner side of the outer groove wall of the receiving groove 241 (i.e., the groove wall on the side away from the center of the fixing member 24, the upper groove wall in fig. 4) is in close contact with the sealing structure 222, and the edge of the outer groove wall of the receiving groove 241 is in contact fit with the turned-up edge 211, so that a sealing line is formed at the circumferential outer side of the gap between the turned-up edge 211 and the bent structure 231 by the outer groove wall of the receiving groove 241, and the sealing structure 222 deformed between the gap and the turned-up edge 211 forms a two.
