[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] See also Figure 1-Figure 4 , is the first embodiment of the utility model, which provides an embedded tank breather, including

[0024] The fuel tank cover body 1, the inner wall of the fuel tank cover body 1 is fixed with a fixing ring 6 by screws or bolts, so that the fixing ring 6 is stably installed;

[0025] The respirator body 4 is provided with an extension portion 41 on the respirator body 4, so that the extension portion 41 is added, and a stabilizing component is provided on the respirator body 4 and the fixing ring 6; the stabilizing component includes an insert block 42, and the insert block 42 is arranged at the bottom of the respirator body 4, so that the insert block 42 is added. A slot 61 for inserting the insert block 42 is opened on the top of the fixing ring 6, and a symmetrically distributed telescopic spring 8 is arranged on the inner side of the slot 61, and a clamping block 7 abutting against the insert block 42 is arranged at one end of the telescopic spring 8. When the respirator body 4 and the fixing ring 6 are spliced, the respirator body 4 is picked up and the insert block 42 is inserted into the slot 61. When the insert block 42 is inserted, the clamping block 7 is squeezed, and the clamping block 7 is squeezed and compresses the telescopic spring 8. The telescopic spring 8 is reset after being compressed, so that the two clamping blocks 7 are clamped on the insert block 42, so that the respirator body 4 and the fixing ring 6 can be quickly spliced, thereby improving the splicing efficiency of the respirator body 4 and the fixing ring 6, and improving the assembly efficiency of the respirator body 4 and the fixing ring 6.

[0026] In this embodiment, preferably, a gap is left between the bottom end of the clamp block 7 and the bottom of the slot 61, so that the clamp block 7 can be more conveniently moved under extrusion, and the top end of the clamp block 7 close to the notch of the slot 61 is an inclined end.

[0027] In this embodiment, preferably, a breathing port 410 is opened at the center of the top of the extension portion 41 , so that the breathing port 410 is opened, and the breathing port 410 is wide at the top and narrow at the bottom, so that air circulation is achieved through the breathing port 410 .

[0028] In this embodiment, preferably, the top of the extension portion 41 is located outside the breathing port 410 and is equipped with oil-absorbing cotton 5, and the oil-absorbing cotton 5 is ring-shaped, thereby realizing the addition of the oil-absorbing cotton 5. When the oil in the oil tank splashes out along the breathing port 410, it can be absorbed by the oil-absorbing cotton 5. Example

[0029] See also Figure 1-Figure 4 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that:

[0030] A protective cover 2 is installed on the top of the fuel tank cover body 1 by screws, so that the protective cover 2 can be firmly installed, and a through hole is opened in the center of the protective cover 2, so that the through hole is opened; a fixing handle 3 is installed on the top of the protective cover 2 on the outside of the through hole, so that the fixing handle 3 is added, and it is more convenient to remove the protective cover 2 through the fixing handle 3; a connecting hole 31 is opened inside the fixing handle 3, so that the connecting hole 31 can be opened, and air circulation can be achieved through the connecting hole 31, and the outer wall of the fuel tank cover body 1 is provided with anti-slip stripes, and the anti-slip stripes increase the convenience of picking up the fuel tank cover body 1.

[0031] The working principle and use process of the utility model are as follows: when the respirator body 4 and the fixing ring 6 are spliced, the respirator body 4 is picked up and the insert block 42 is inserted into the slot 61. When the insert block 42 is inserted, the clamp block 7 is squeezed, and the clamp block 7 is squeezed and compresses the telescopic spring 8. The telescopic spring 8 is compressed and reset, so that the two clamp blocks 7 are clamped on the insert block 42, so that the respirator body 4 and the fixing ring 6 are quickly spliced, which improves the splicing efficiency of the respirator body 4 and the fixing ring 6, and improves the assembly efficiency of the respirator body 4 and the fixing ring 6.
