The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figure 1-6 The present invention provides a technical solution: For an example, please refer to... Figure 1 , 2 3, 4, 5 and 6, a portable catering waste oil recycling pump, including a handheld main body that is easy to hold and operate with one hand, a pump body structure 11 that provides suction power, and a set of oil extraction pipes for inserting into the oil and having a filtering and cleaning function. The interior of the handheld main body forms an installation space to accommodate other functional components. The overall design is ergonomic. Users can hold it with the handle 2 and use the angled handle 3 to help stabilize the equipment and adjust the suction angle.

[0022] The main body of the handheld unit is a streamlined shell 1, which is made of lightweight and sturdy engineering plastic. The shell 1 has an internal mounting cavity 8, which is divided into multiple independent cavities by one or more partitions 26 to isolate electrical components from mechanical components or different functional modules, thereby improving safety and ease of maintenance. The upper end of the shell 1 is fixedly connected to a handle 2 for easy gripping, and the lower end is connected to the filter connection end of the oil suction pipe by a forward and downward angled handle 3. The design of the angled handle 3 allows the user to hold the device more naturally and accurately place the oil suction pipe 7 into the waste oil container, while reducing hand fatigue during long-term operation. On the upper surface of the shell 1, a control panel containing a switch, speed control knob or indicator light is embedded, which is electrically connected to the internal control terminal 9.

[0023] Please refer to Figure 3 , 56. The pump body structure 11 is the core of generating suction force. It is fixed to an independent cavity divided by the partition 26 in the mounting cavity 8 by bolts or buckles. The pump body structure 11 mainly includes a pump body 11. The pump body 11 has a precision cavity 23 machined inside. One end of the cavity 23 is the oil inlet end 22, which is connected to the filter connection end below through a connecting pipe 21. The other end is the oil outlet end, which is directly connected to the oil outlet 5 fixed on the side of the outer shell 1. The recovered waste oil is finally discharged into the designated collection bucket through the oil outlet 5.

[0024] Inside the cavity 23, a pair of meshing drive gears 24 and driven gears 25 are installed. A convex shaft is connected to the center of the drive gear 24, extending out of the pump body 11 and connected to the output shaft of a drive motor 10 fixed in the mounting cavity 8. When the equipment is started, the control terminal 9 drives the motor 10 according to the user's instructions, which drives the drive gear 24 to rotate, and in turn drives the driven gear 25 to rotate in the opposite direction. During the meshing and rotation of the two gears, the tooth gap and the inner wall of the pump body form a closed space. This space moves from the oil inlet end 22 to the oil outlet end as the gears rotate, thereby continuously drawing oil from the inlet and discharging it from the outlet, forming a stable vacuum suction. This gear pump has a compact structure and high efficiency, and is very suitable for pumping viscous waste cooking oil.

[0025] Please refer to Figure 3 and 4 The main body of the oil suction pipe is a flexible oil suction pipe 7, whose oil suction end can extend into the bottom of the waste oil container. The upper end of the oil suction pipe 7 is connected to the handheld main body through a filter connection end. The filter connection end mainly includes a cylindrical filter cylinder 6 that is fixedly connected to the lower end of the outer shell 1.

[0026] The lower end of the filter cartridge 6 is machined with a convex ring 16 with internal threads. The upper end of the oil suction pipe 7 is connected to a docking seat 18. A connecting seat 17 is fixed above the docking seat 18. The outer wall of the connecting seat 17 is machined with an external thread that matches the internal thread of the convex ring 16, thereby realizing a detachable screw connection between the filter cartridge 6 and the oil suction pipe 7, which is convenient for cleaning or replacing parts. Multiple channels 19 are opened through the side of the connecting seat 17, and oil can enter the interior of the filter cartridge 6 through these channels.

[0027] A filter screen cylinder 12 is detachably installed on the upper end face of the connector 17 via a threaded groove. The lower end of the filter screen cylinder 12 is formed with a screw-on end 20 that mates with the threaded groove. The filter screen cylinder 12 is used to intercept solid impurities such as food residue and bone fragments in the oil, preventing them from entering the pump body 11 and causing damage or blockage.

[0028] One of the key improvements of this invention is the inclusion of a rotating cleaning component for automatically cleaning accumulated impurities on the filter cylinder 12, which significantly extends continuous operation time and reduces the frequency of manual cleaning.

[0029] The rotating cleaning assembly includes a fixed rod 13 that is vertically fixed to the center of the upper end face of the connecting seat 17. Multiple scrapers a14 are fixedly connected to the fixed rod 13 radially. The side edges of these scrapers a14 always remain in contact with the inner side of the filter cylinder 12.

[0030] When cleaning is required, separate the connecting seat 17 from the convex ring 16, then manually rotate the filter cylinder 12 and clean its inner wall with multiple scrapers a14. During the disassembly of the connecting seat 17, the scrapers b15 on the outside of the filter cylinder 12 clean the cylinder wall and large deposits of the filter cylinder 6.

[0031] The upper part of the mounting cavity 8 is provided with a control terminal 9, which is usually a module integrating components such as a control circuit board, microcontroller and relay. The control terminal 9 is fixed to the partition 26 by several limiting plates 27 set on its side. The control terminal 9 is electrically connected to the control panel and the drive motor 10. It is responsible for receiving user commands, controlling the start, stop and speed of the motor, and can integrate the automatic cleaning trigger logic based on current or time as described above. Through reasonable circuit layout and software control, one-button operation and intelligent maintenance of the equipment are realized.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
