[0018] 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.
[0019] like Figures 1 to 4 As shown, this utility model provides a detachable fuel filter, including a fuel filter body 1. A water collection cup 2 is provided at the bottom of the fuel filter body 1 and communicates with its interior. A drain pipe 3 is provided at the bottom of the water collection cup 2 and communicates with its interior. A drain valve 4 is installed at the end of the drain pipe 3. A guide rod is installed inside the drain pipe 3. The guide rod is driven by a drive module. The drive module is used to drive the guide rod to reciprocate within the drain pipe 3 so that the guide rod can unclog the drain pipe 3.
[0020] Water collection cup 2 is made of transparent plastic. The transparent plastic material allows for a clearer view of the sediment buildup inside the water collection cup 2, enabling timely manual removal of sediment and water.
[0021] The guide rod includes a main rod body 7, a secondary rod body 8, and a helical blade 9. The main rod body 7 and the secondary rod body 8 are coaxially rotatably connected. The main rod body 7 is connected to the drive module for transmission. The helical blade 9 is coaxially fixed on the secondary rod body 8.
[0022] A limiting rod 11 is fixedly installed at the bottom of the auxiliary rod body 8. A spiral guide groove 10 is opened inside the drain pipe 3, and a slider is slidably installed in the spiral guide groove 10. The limiting rod 11 is fixedly connected to the slider. By setting the spiral guide groove 10, the auxiliary rod body 8 can rotate while reciprocating. In conjunction with the spiral blades 9 made in its fan, the spiral blades 9 can crush the sediment. At the same time, the rotating spiral blades 9 can also push the sediment towards the lower end of the drain pipe 3, thereby pushing the sediment away and further improving the unblocking effect.
[0023] The drive module includes a crankshaft 5, a connecting rod 6, and a knob 12. The crankshaft 5 is housed inside the water collection cup 2, and is correspondingly positioned with the guide rod. Both ends of the crankshaft 5 are rotatably connected to the inner wall of the water collection cup 2. The crankshaft 5 is connected to the guide rod via the connecting rod 6. One end of the crankshaft 5 extends outwards to the outside of the water collection cup 2 and is fixedly mounted with the knob 12. The two ends of the connecting rod 6 are movably connected to the crankshaft 5 and the guide rod, respectively. This crankshaft 5 and connecting rod 6 structure is a common transmission structure that can more efficiently drive the guide rod. It is simple in structure and highly efficient. In practical use, if automated unblocking is required, the knob 12 can be replaced with a servo motor to drive the rotation of the crankshaft 5.
[0024] The crankshaft is made of 304 stainless steel. Since the crankshaft needs certain strength and is placed in the water collecting cup 2 and is soaked in water and sediment for a long time, in order to avoid corrosion and fatigue fracture, the 304 stainless steel material is used to greatly prolong the service life of the device.
[0025] The drain valve 4 is a ball valve. The ball valve has better waterproof effect, mainly in its sealing performance and high pressure resistance. The ball valve is a half-spherical body inside, has large water outlet capacity, good sealing performance, high pressure resistance, and is suitable for installation in narrow space without worrying about water leakage.
[0026] When the water collecting cup 2 contains a lot of water, the drain valve 4 is opened, and the drain pipe 3 is blocked due to the presence of a lot of sediment in the water collecting cup 2, which causes the drain pipe 3 to not drain smoothly. At this time, the operator can rotate the knob 12 on the water collecting cup 2, the knob 12 drives the crankshaft 5 to rotate, the crankshaft 5 drives the guide rod to make reciprocating motion in the drain pipe 3 through the connecting rod 6. Since the guide rod is composed of the main rod body 7 and the auxiliary rod body 8, when working, the main rod body 7 makes linear reciprocating motion along the drain pipe 3, and the auxiliary rod body 8 connected to the front end thereof is driven to make spiral motion along the spiral guide slot 10 formed in the inner wall of the drain pipe 3. The spiral blade 9 arranged on the auxiliary rod body 8 stirs the sediment in the drain pipe 3, grinds the sediment, so that the sediment does not block the drain pipe 3, thereby achieving the purpose of dredging the drain pipe 3, and further enabling the sediment and water in the water collecting cup 2 to be smoothly discharged through the drain pipe 3.
