[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1 to 4 This utility model provides a technical solution: a fuel filter element with a moisture detection sensor, including a filter canister 1, in which a filter element for filtering fuel is placed, which is prior art and will not be described in detail here. A cover 2 is fixedly installed at the bottom of the filter canister 1 by welding. The cover 2 is provided with a through hole, and a water collection component 3 for draining the filtered and stagnant water in the filter canister 1 is installed in the through hole by welding.
[0016] The water collection assembly 3 includes a water collection pipe 4 welded and fixed in the through hole of the cover 2. A fixing ring 5 is welded and installed on the outer wall of the water collection pipe 4. Several lifting grooves 8 are provided on the surface of the water collection pipe 4 below the fixing ring 5. Each lifting groove 8 is provided with a matching lifting slider. The lifting slider and the inner wall of the top of the lifting groove 8 are connected by a connecting spring 9. The outer walls of the several lifting sliders are connected by welding to a movable ring 10. The top of the movable ring 10 is movably fitted with a limiting ring 7 to restrict its movement space. The limiting ring 7 is fixedly installed on the outer wall of the water collection pipe 4 by welding. The bottom end of the water collection pipe 4 is movably fitted with a sealing ring. A baffle 11 is used to block the bottom opening of the water collection pipe 4. A sealing rubber ring is installed on the top of the baffle 11 by adhesive. The bottom of the water collection pipe 4 is provided with a hidden groove that matches the sealing rubber ring. Several connecting rods 12 are connected to the top of the baffle 11 and the bottom of the movable ring 10 by welding. That is, if it is necessary to drain the water accumulated in the filter tank 1 during use, the baffle 11 can be controlled to move downward to open the bottom opening of the water collection pipe 4 to drain the water. After the water is drained, the connecting spring 9 can be contracted to make the baffle 11 move vertically upward to reseal the bottom opening of the water collection pipe 4, thus preventing excessive fuel from being discharged and wasting it.
[0017] The bottom end of the fixed ring 5 is provided with a buffer assembly for buffering drainage. The buffer assembly includes a buffer tank 6. The bottom end of the fixed ring 5 is provided with a threaded groove. The buffer tank 6 is installed in the threaded groove for screwing and fixing to the bottom end of the fixed ring 5. That is, the outer wall of the buffer tank 6 is also provided with threads that are compatible with the threaded groove. The buffer tank 6 can temporarily collect the collected water and fuel discharged from the water collection pipe 4. The bottom plate of the buffer tank 6 is provided with a through hole, and the water outlet pipe 16 is fixedly installed in the through hole by welding. The bottom end of the baffle 11 is installed with a vertical rod 13 by welding. The bottom plate of the buffer tank 6 is provided with a through hole with the same diameter as the vertical rod 13. The vertical rod 13 extends to the bottom of the buffer tank 6 through the through hole, and the inner wall of the through hole is provided with a hidden groove. A rubber ring is installed in the hidden groove by adhesive to prevent water from flowing out in large quantities from the gap between the vertical rod 13 and the inner wall of the through hole.
[0018] The bottom end of the upright 13 is movably fitted with a horizontal plate 14. The horizontal plate 14 is provided with a threaded through hole, and a threaded rod is provided in the threaded through hole. The bottom end of the upright 13 is provided with a threaded groove with the same diameter as the threaded through hole. By passing the threaded rod through the horizontal plate 14 and rotating it into the threaded groove at the bottom end of the upright 13, the position of the horizontal plate 14 can be fixed. A sealing cap 15 that can block the bottom opening of the water outlet pipe 16 is fixedly installed on the horizontal plate 14 by welding. The top of the sealing cap 15 is provided with a groove with the same diameter as the outer wall of the water outlet pipe 16, and a hidden groove is provided on the inner wall of the groove on the sealing cap 15. A sealing rubber ring is also provided in the hidden groove.
[0019] Working principle: During use, the buffer tank 6 is fixedly installed at the bottom of the fixing ring 5 by screwing. At this time, the cap 15 is fitted onto the outer wall of the water outlet pipe 16, and the threaded rod passes through the horizontal plate 14 to connect the upright rod 13, thus fixing the position of the cap 15 and the horizontal plate 14. When using the filter tank 1 to filter fuel, the water in the fuel accumulates in the water collection pipe 4. When it is necessary to drain the water in the water collection pipe 4, the connection between the threaded rod and the upright rod 13 is rotated downward by controlling the threaded rod. At this time, the upright rod 13 is pulled downward, which can drive the baffle 11 to move downward, so that the opening at the bottom of the water collection pipe 4 is opened, and the accumulated water is discharged into the buffer tank 6 and then slowly discharged through the water outlet pipe 16.
