[0031] Reference Figures 1 to 4 An oil filter includes a frame 100, an oil tank 200, a circulation pump 300, and an oil injection gun 400. The oil tank 200 is detachably connected to the frame 100. A filter screen 210 is installed in the oil tank 200, dividing the oil tank 200 into an upper space and a lower space. An oil suction hole 220 is provided at the bottom of the oil tank 200, and the oil suction hole 220 is connected to an oil outlet pipe 230. The circulation pump 300 is installed on the frame 100 and circulates... The inlet end of pump 300 extends out of frame 100. The free end of oil outlet pipe 230 is detachably connected to the inlet end of circulation pump 300. The inlet end of circulation pump 300 is connected to oil outlet pipe 230. Circulation pump 300 is used to draw oil from oil tank 200 and pass the oil through filter screen 210. One end of oil injection gun 400 is connected to the outlet end of circulation pump 300. The other end of oil injection gun 400 is used to insert into the upper space of oil tank 200 or to inject oil to the outside. The oil tank 200 is used to hold the used cooking oil. The filter screen 210 and the circulation pump 300 work together. The circulation pump 300 forces the cooking oil through the filter screen 210, trapping food residue above the filter screen. The cooking oil drawn by the circulation pump 300 is then injected back into the upper space of the oil tank 200 through the oil gun 400. This cycle of filtration is repeated until the cooking oil reaches a standard that allows it to be reused. The oil is then injected back into the fryer through the oil gun 400. The oil filter has a simple structure and is easy to operate. The circulating filtration method ensures that the cooking oil is filtered more thoroughly, preventing burnt food residue from affecting the quality of fried foods.

[0032] In some embodiments, a protective cover 500 is also included, which is connected to the frame 100 and covers the circulation pump 300. A receiving pipe 510 is provided on the protective cover 500, connecting to the inlet end of the circulation pump 300. A plug-in structure 231 is provided at the free end of the oil outlet pipe 230, used to insert the receiving pipe 510 to connect the oil outlet pipe 230 to the circulation pump 300. The protective cover 500 isolates and protects the circulation pump 300. The design of the receiving pipe 510 and the plug-in structure 231 facilitates oil outlet... Pipe 230 can be quickly connected to the circulating pump 300, making it more convenient to replace the oil tank 200. It can be understood that the plug-in structure 231 actually has multiple annular protrusions at the free end of the oil outlet pipe 230. The annular protrusions are evenly distributed along the axial direction of the free end of the oil outlet pipe 230. Correspondingly, multiple annular grooves are provided on the inner peripheral wall of the insertion pipe 510. A sealing ring is embedded in the annular groove. When the plug-in structure 231 is inserted, the sealing ring embedded in the annular groove can both strengthen the connection and seal, preventing oil from leaking out of the insertion pipe 510.

[0033] In some embodiments, a gap is provided between the protective cover 500 and the frame 100, and heat dissipation vents 520 are provided on the bottom plate and side wall of the protective cover 500.

An oil inlet hole 240 is provided on the top plate of the oil tank 200. The oil injection gun 400 is inserted from the upper end of the plunger 530 and extends to the oil inlet hole 240. The plunger 530 serves to load the oil injection gun 400 and also to guide the oil injection gun 400 so that it injects oil into the oil tank 200, thereby achieving oil circulation and filtration.

[0035] In some embodiments, the oil tank 200 is provided with an oil filling port 280, and a filter tank 250 is detachably connected to the oil tank 200. The filter tank 250 is installed below the oil filling port 280 and is used to filter out impurities in the added oil. The oil filling port 280 facilitates the addition of external oil to the oil tank 200. It is understood that the filter tank 250 is provided with hook structures on both sides, which are hooked to the edge of the oil tank 200.

[0036] In some embodiments, a cover 260 is detachably connected to the fuel tank 200. The cover 260 is used to seal the fuel filler port 280. It should be noted that an insert is provided at the lower end of the cover 260. The insert is inserted into the fuel filler port 280 to limit the cover 260, which in turn allows the cover 260 to better seal the fuel filler port 280. Furthermore, a rubber sealing ring can be provided at the lower end of the cover 260 to prevent fuel from splashing out.

[0037] In some embodiments, the bottom of the oil tank 200 is provided with a groove 270, the oil suction hole 220 is provided at the bottom of the groove 270, and the filter screen 210 is provided with a support part 211.
