[0031] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0032] Figure 1 A schematic diagram of the structure of the oil filter device 1 according to an embodiment of the present application is shown.Figure 2 FIG. 1 is a schematic diagram showing the structure of the oil filter device 1 according to an embodiment of the present application when the power device 30 is free of the housing 31. Figure 1 and Figure 2 As shown, the oil filter device 1 includes a frame 10, an oil reservoir 20 and a pipeline group 40. Specifically, the oil reservoir 20 is detachably arranged on the frame 10, and the interior of the oil reservoir 20 defines a cavity for storing oil, and the bottom wall of the cavity is provided with a filter membrane layer for filtering the oil, and the bottom of the oil reservoir 20 is provided with an oil outlet connected to the cavity, and the oil filtered by the filter membrane layer is discharged through the oil outlet. The power device 30 is arranged on the frame 10 and is located above the oil reservoir 20. The power device 30 includes an oil inlet end 30a and an oil outlet end 30b, and the oil inlet end 30a is located on the upper side of the oil outlet end 30b. The pipeline group 40 includes an oil inlet pipe 41 and an oil outlet pipe 42. The first end of the oil inlet pipe 41 is connected to the interior of the oil storage tank 20, the second end of the oil inlet pipe 41 is connected to the oil inlet end 30a of the power device 30, the first end of the oil outlet pipe 42 is connected to the oil outlet end 30b of the power device 30, and the second end of the oil outlet pipe 42 is connected to the oil gun 71.

[0033] The oil filter device 1 of the embodiment of the present application can be used to filter the oil to be processed and output the processed oil to a designated container. The oil to be processed can be edible oil, specifically shortening. Of course, the type of oil is not limited thereto, and can be any type of oil, such as lubricating oil.

[0034] Exemplarily, the power device 30 may include an outer shell 31 and a pump body 32 arranged inside the outer shell 31, and the oil inlet end 30a and the oil outlet end 30b are respectively arranged on the pump body 32. The oil to be treated enters the pump body 32 through the oil inlet end 30a. The centrifugal force provided by the pump body 32 during operation enables impurities and moisture in the oil to be separated from the oil itself, thereby achieving the purpose of filtering impurities and moisture. The filtered oil flows out through the oil outlet end 30b.

[0035] It should be noted that in the embodiment of the present application, by setting the oil inlet end 30a on the upper side of the oil outlet end 30b, that is, the pump body 32 adopts the setting mode of top oil inlet and bottom oil outlet, the residual oil in the pump body 32 can be easily discharged through the lower oil outlet end 30b under the action of gravity, thereby avoiding the accumulation of oil in the pump body 32 and reducing the residual oil, thereby reducing the occurrence of blockage of the power device 30 due to the residual oil and solidification after the temperature drops, thereby improving the reliability and stability of the power device 30.

[0036] In some specific examples, the oil reservoir 20 can be a cooking container for holding cooking oil. When the oil needs to be filtered, the oil reservoir 20 can be directly placed on the frame 10 of the oil filter device 1. The oil in the oil reservoir 20 enters the power device 30 through the oil inlet pipe 41 under the pumping of the power device 30, and then is discharged through the oil outlet pipe 42. When the oil passes through the filter membrane layer, solid impurities in the oil cannot pass through the filter membrane layer, thereby separating the solid impurities from the oil, and the filtered oil enters the oil inlet pipe 41 through the oil outlet. The filter membrane layer can be a film of any material, for example, a polymer film made of polytetrafluoroethylene, polyimide or polypropylene can be selected, and a glass fiber membrane can also be selected.

[0037] It is understandable that the oil output from the output end 30b of the power device 30 can be returned to the oil storage tank 20 for re-filtration after being discharged through the oil outlet pipe 42, so as to further improve the filtering effect of the oil.

[0038] In addition, by arranging the power device 30 on the upper side of the oil storage tank 20, the power device 30 and the oil storage tank 20 are integrated on the frame 10 in the vertical direction. On the one hand, it is beneficial to reduce the placement height of the oil storage tank 20, thereby facilitating the placement and removal of the oil storage tank 20. On the other hand, it improves the integration of the oil filter device 1, which is beneficial to reducing the external dimensions of the oil filter device 1, thereby saving the space occupied by the oil filter device 1.

[0039] In summary, the oil filter device 1 according to the embodiment of the present application can reduce the residual oil in the power device 30, thereby improving the working stability and reliability of the oil filter device 1, and is convenient to operate and use, and is also beneficial to reducing the external dimensions of the oil filter device 1 and saving placement space.

[0040] Figure 3 FIG. 1 is a schematic diagram showing a partial structure of an oil filter device 1 according to an embodiment of the present application. Figures 1 to 3 As shown, in one embodiment, an oil drain pipe 21 is provided at the bottom of the oil storage tank 20, and the two ends of the oil drain pipe 21 respectively have an oil inlet 211 and an oil outlet 212, and the oil inlet 211 and the oil outlet 212 are both provided on the top wall of the oil drain pipe 21 and are spaced apart in the length direction of the oil drain pipe 21, the oil inlet 211 is used to communicate with the interior of the oil storage tank 20, and the oil outlet 212 is used to be pluggably connected to the first end of the oil inlet pipe 41.

[0041] Exemplarily, the oil drain pipe 21 is disposed below the oil reservoir 20 and fixed to the bottom of the oil reservoir 20. The oil drain pipe 21 has a first end and a second end in its length direction, wherein the first end extends to the bottom of the oil reservoir 20, the second end extends to the outside of the oil reservoir 20, and the second end is exposed from the bottom of the oil reservoir 20. The oil inlet 211 is disposed at the first end, and the oil inlet 211 is formed on the top wall of the oil drain pipe 21, so that the opening direction of the oil inlet 211 is set upward, so that it can be connected with the oil outlet at the bottom of the oil reservoir 20. The oil outlet 212 is disposed at the second end, and the oil outlet 212 is also formed on the top wall of the oil drain pipe 21, so that the opening direction of the oil outlet 212 is also set upward, so that it can be pluggably connected with the first end of the oil inlet pipe 41 located on the upper side.

[0042] In some specific examples, the oil outlet 212 is pluggably connected to the first end of the oil inlet pipe 41, and at least a portion of the first end of the oil inlet pipe 41 can be inserted into the oil outlet 212 and extend to the interior of the oil drain pipe 21, thereby connecting the interior of the oil drain pipe 21 to the interior of the oil inlet pipe 41.

[0043] Through the above-mentioned implementation mode, the oil inlet pipe 41 is connected with the inside of the oil storage tank 20 through the oil drain pipe 21, and the setting mode of the oil inlet port 211 and the oil outlet port 212 of the oil drain pipe 21 simplifies the connection mode between the oil drain pipe 21 and the oil storage tank 20 and the oil inlet pipe 41, thereby reducing the connection difficulty of the pipeline group 40 and improving the convenience of installation and disassembly of the oil storage tank 20.

[0044] like Figure 3 As shown, in one embodiment, an end of the oil drain pipe 21 adjacent to the oil outlet 212 has an oil drain port 213 , and the oil drain port 213 is provided with a first oil drain valve 51 .

[0045] Exemplarily, the oil drain port 213 is provided at the second end of the oil drain pipe 21 extending to the outside of the oil reservoir 20, and the first oil drain valve 51 is installed at the oil drain port 213. The first oil drain valve 51 may include a butt joint pipe and a valve, the valve being rotatably provided inside the butt joint pipe, and the valve being in transmission connection with a handle outside the butt joint pipe, and the valve being driven to rotate by the rotation of the handle, thereby adjusting the opening of the butt joint pipe to open or close the first oil drain valve 51.

[0046] Through the above-mentioned embodiment, the residual oil in the oil storage tank 20 or the oil inlet pipe 41 can be discharged through the first oil drain valve 51, thereby reducing the residual oil in the oil storage tank 20 and the oil inlet pipe 41, and further reducing the probability of blockage of the pipeline group 40 due to oil solidification.

[0047] Continue to refer to Figure 3As shown, in one embodiment, the oil inlet pipe 41 includes a first connecting section 411, a second connecting section 412 and a third connecting section 413 connected in sequence, the input end of the first connecting section 411 forms the first end of the oil inlet pipe 41, the output end of the first connecting section 411 is connected to the input end of the third connecting section 413 through the second connecting section 412, and the output end of the third connecting section 413 forms the second end of the oil inlet pipe 41.

[0048] In some optional examples, the first connecting section 411 includes a vertical section 411a and a bending section 411b connected to each other, the vertical section 411a is arranged in the vertical direction and the lower end forms the first end of the oil inlet pipe 41, the upper end of the vertical section 411a is connected to one end of the bending section 411b, the other end of the bending section 411b is connected to the input end of the second connecting section 412 arranged in the horizontal direction, the output end of the second connecting section 412 is connected to the lower end of the third connecting section 413 arranged in the vertical direction, and the upper end of the third connecting section 413 is connected to the oil inlet end 30a of the power unit 30 through a turning joint.

[0049] It can be understood that the vertical segment 411a is arranged along the vertical direction, which means that the central axis of the vertical segment 411a is arranged along the vertical direction; the second connecting segment 412 is arranged along the horizontal direction, which means that the central axis of the second connecting segment 412 is arranged along the horizontal direction; the third connecting segment 413 is arranged along the vertical direction, which means that the central axis of the point connecting segment is arranged in the vertical direction.

[0050] More specifically, the vertical section 411a and the bending section 411b can be an integrally formed part. The bending section 411b includes a first pipe section and a second pipe section connected to each other, the central axis of the first pipe section is arranged in the vertical direction, and the end of the first pipe section is connected to the upper end of the vertical section 411a, the central axis of the second pipe section is arranged in the horizontal direction, and the end of the second pipe section is connected to the input end of the second connecting section 412. Among them, the vertical section 411a and the bending section 411b can be an integrally formed part. The output end of the second connecting section 412 can be connected to the third connecting section 413 through a turning joint, and the central axes of the two ends of the turning joint are arranged in the horizontal direction and the vertical direction respectively, so that the two ends of the turning joint can be connected to the output end of the second connecting section 412 and the input end of the third connecting section 413 respectively. Among them, the output end of the second connecting section 412 can be inserted into the end of the turning joint arranged in the horizontal direction, and the input end of the third connecting section 413 can be inserted into the end of the turning joint arranged in the vertical direction.

[0051] Through the above implementation, the number of turning connections between the multiple connection sections included in the oil inlet pipe 41 can be reduced, which is beneficial to further reduce the probability of oil remaining in the oil inlet pipe 41.

[0052] Continue to refer to Figure 3As shown, in one embodiment, the oil outlet pipe 42 is connected to the oil outlet end 30b of the power device 30 through a bend joint, and the oil outlet pipe 42 is arranged in a horizontal direction.

[0053] It can be understood that the oil outlet pipe 42 is arranged in the horizontal direction, which means that the central axis of the oil outlet pipe 42 is arranged in the horizontal direction.

[0054] Exemplarily, the bend joint has two ends with opening directions perpendicular to each other, wherein the end facing upward is connected to the oil outlet end 30b of the power device 30 located at the lower side, and the end facing horizontally is connected to the first end of the oil outlet pipe 42.

[0055] Thus, the oil outlet pipe 42 can be connected to the oil outlet end 30 b of the power device 30 , and the oil outlet pipe 42 can be placed in a horizontal direction, which is beneficial to further reduce the residual oil in the oil outlet pipe 42 .

[0056] Optionally, the oil filtering device 1 also includes a three-way joint 60, the first end of the three-way joint 60 is connected to the second end of the oil outlet pipe 42, the second end of the three-way joint 60 is connected to the oil guide pipe 70, the oil gun 71 is arranged on the oil guide pipe 70, and the third end of the three-way joint 60 is provided with a second oil drain valve 52.

[0057] For example, the first end of the three-way joint 60 is coaxially arranged with the central axis of the third end of the three-way joint 60, and the opening directions of the two are arranged in opposite directions. The central axis of the second end of the three-way joint 60 is respectively perpendicular to the central axis of the first end and the third end of the three-way joint 60. Thus, the second end of the oil outlet pipe 42 can be connected to the oil guide pipe 70 and the second oil drain valve 52 respectively. Among them, the structure of the second oil drain valve 52 can be set accordingly with reference to the first oil drain valve 51, and will not be repeated here.

[0058] In some specific examples of the present application, the oil guide tube 70 can be made of a flexible material so that the oil guide tube 70 itself has a certain degree of deformation ability. The oil gun 71 is provided with an operating valve for opening or closing its internal flow path, and the user can guide the oil in the oil guide tube 70 by controlling the operating valve. Such a configuration can facilitate the user to guide the filtered oil into a container placed at a designated position by holding the oil gun 71, thereby improving the user's operating convenience.

[0059] Optionally, the second end of the three-way joint 60 is threadedly connected to the connecting end of the oil guide pipe 70, and the central axis of the second end of the three-way joint 60 is coaxial with the central axis of the connecting end of the oil guide pipe 70 and is arranged parallel to the horizontal direction.

[0060] Exemplarily, the outer wall surface of the connecting end of the oil guiding tube 70 is provided with a threaded structure, and the inner wall surface of the second end of the three-way joint 60 is provided with a threaded matching structure. The connecting end of the oil guiding tube 70 can be inserted into the interior of the second end of the three-way joint 60, and the threaded connection between the connecting end of the oil guiding tube 70 and the second end of the three-way joint 60 is achieved through the threaded matching between the threaded structure and the threaded matching structure.

[0061] Through the above implementation, the difficulty of assembling the two is reduced, and it is helpful to improve the tightness of the connection between the two.

[0062] like Figure 1 and Figure 2 As shown, in one embodiment, a plurality of rollers 11 are installed at the bottom of the frame 10 .

[0063] With such arrangement, the oil filter device 1 can move relative to the ground through the rolling friction between the multiple rollers 11 and the ground, thereby improving the mobility of the oil filter device 1.

[0065] Exemplarily, the lower bearing portion 13 includes a bottom support frame, and the upper surface of the bottom support frame is formed with a first bearing surface for bearing the oil storage tank 20. The bottom support frame may include a supporting crossbeam and a supporting longitudinal beam connected in sequence, and the first bearing surface may be formed by at least part of the upper surface of the supporting crossbeam and at least part of the upper surface of the supporting longitudinal beam. The upper bearing portion 12 includes a supporting column and a supporting plate, wherein the number of the supporting columns is multiple and the lower ends are connected to the bottom support frame, and each supporting column is arranged in a vertical direction. The supporting plate is connected to the upper ends of the multiple supporting columns, and the upper side of the supporting plate forms a second bearing surface for bearing the power device 30.

[0066] The shape of the armrest 80 may be generally U-shaped, and include two side tubes spaced apart and arranged opposite to each other in the width direction of the oil filter device 1, and the ends of the two side tubes are rotatably connected to the upper side of the support plate through hinges. The hinge is provided with a limit groove, and the end of the side tube is provided with a limit part that forms a limit fit with the limit groove, so as to limit the rotation angle of the armrest 80 through the limit fit between the limit part and the limit groove. In some optional examples, the rotation axis of the armrest 80 may be arranged parallel to the width direction of the oil filter device 1, so that the armrest 80 can rotate forward or backward.

[0067] With such arrangement, the user can push the oil filter device 1 to move by means of the armrest 80 , thereby further improving the mobility of the oil filter device 1 .
