[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-2 A self-sealing pipeline oil suction filter comprises a cylinder 1 and a filter element 2 located in the cylinder 1. A partition plate 3 is provided inside the cylinder 1 for dividing the inside of the cylinder 1 into a first cavity 101 and a second cavity 102. The filter element 2 is arranged in the second cavity 102. An oil inlet 103 communicating with the first cavity 101 is provided at the top of the cylinder 1, and an oil outlet 104 communicating with the second cavity 102 is provided at the side of the cylinder 1.

[0019] A mounting hole 301 is provided through the middle of the partition plate 3 , and a self-sealing component 4 for sealing the mounting hole 301 is provided in the first cavity 101 .

[0020] The utility model realizes the blocking effect on the installation hole 301 through the self-sealing component 4, separates the filter element 2 in the second cavity 102 from the oil in the first cavity 101, and avoids oil leakage when replacing the filter element 2; at the same time, a disassembly component 5 is provided at the bottom of the cylinder 1 to facilitate the replacement of the filter element.

[0021] In an optional embodiment of the present invention, the self-sealing component 4 includes a tube body 401 slidably sealed with the mounting hole 301, a mounting plate 402 provided at one end of the tube body 401 close to the oil inlet 103, a sealing plate 403 provided at the other end of the tube body 401, a spring 404 connecting the mounting plate 402 and the top inner wall of the first cavity 101, a first through hole 405 penetrating the mounting plate 402, and a second through hole 406 penetrating the side wall of the tube body 401. After the oil enters the first cavity 101 through the oil inlet 103, the tube body 401 is sealed by the first The cavity 101 moves toward the second cavity 102, and the spring 404 is stretched. At this time, the second through hole 406 enters the second cavity 102, and the oil enters the tube body 401 through the first through hole 405, and enters the second cavity 102 through the second through hole 406, and flows to the oil outlet 104 after being filtered by the filter element 2; after the oil stops entering, the spring 404 resets and drives the tube body 401 to move from the second cavity 102 to the first cavity 101, and the second through hole 406 enters the first cavity 101. At this time, replacing the filter element 2 can ensure that there is no oil leakage.

[0022] In an optional embodiment of the present invention, a limiting ring plate 407 is provided on the edge of the mounting plate 402. The limiting ring plate 407 in this embodiment abuts against the partition plate 3. By setting the limiting ring plate 407, the movement of the tube body 401 can be limited to prevent the tube body 401 from excessively entering the second cavity 102.

[0023] In an optional embodiment of the present invention, a sealing ring 408 is embedded in one end of the tube body 401 close to the sealing plate 403. Through the setting of the sealing ring 408, the spring 404 is reset and drives the tube body 401 to move from the second cavity 102 to the first cavity 101. Then, the tube body 401 and the inner wall of the mounting hole 301 are sealed and connected to avoid oil leakage when replacing the filter element 2.

[0024] In an optional embodiment of the present invention, in order to improve the stability of the filter element 2 in the second cavity 102, a card slot 302 is opened at the bottom of the partition plate 3, and the filter element 2 and the card slot 302 are snap-fitted.

[0025] In an optional embodiment of the utility model, a filter cover 5 is provided at the bottom of the cylinder 1, and the filter cover 5 and the inner wall of the cylinder 1 are threadedly matched. By setting the filter cover 5 at the bottom of the cylinder 1, the filter element 2 can be taken out from the bottom of the cylinder 1 by simply rotating the filter cover 5, thereby facilitating the replacement of the filter element 2.

[0026] In an optional embodiment of the present invention, a second card slot 501 is opened on the filter cover 5, and the filter element 2 and the second card slot 501 are snap-fitted together. By snap-fitting one end of the filter element 2 with the second card slot 501, the stability of the filter element 2 in the second cavity 102 is improved.

[0027] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
