[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: An oil-water separator for a range hood, see Figures 1-6As shown, it includes a separation box 1, a flap 2, a sieve plate 3, an oil-water separation plate 4, a collecting frame 5 and a handle 50. The separation box 1 is rotatably provided with a flap 2 on the top. The separation box 1 is opened by rotating the flap 2 upward, which is convenient for inspection and cleaning of the interior of the separation box 1. The separation box 1 is provided with a sieve plate 3 inside. The separation box 1 is provided with an oil-water separation plate 4 inside. A polytetrafluoroethylene filter membrane is attached to the oil-water separation plate 4. The polytetrafluoroethylene membrane has extremely high hydrophobicity and can effectively block water molecules, so that oil droplets pass through the oil-water separation plate 4, and water molecules and other impurities remain on the oil-water separation plate 4. A collecting frame 5 is slidingly provided on the front side of the separation box 1. The front side of the collecting frame 5 is fixedly connected to the handle 50 by welding. Two connectors 6 are connected to the flap 2. The piston box 7 is fixedly connected to the flap 2. The bottom of 7 is connected and communicated with two one-way drainage pipes 8, the one-way drainage pipes 8 are connected to the adjacent connecting head 6, the top of the piston box 7 is connected and communicated with two one-way liquid extraction pipes 9, one end of the one-way liquid extraction pipe 9 is connected to a docking pipe 10, a piston rod 11 is slidingly arranged inside the piston box 7, a connecting plate 12 is installed on the right side of the piston rod 11, an electric slide rail 13 is arranged on the front side of the piston box 7, an electric slider 14 is slidingly arranged on the electric slide rail 13, the connecting plate 12 is fixedly connected to the electric slider 14, the pull handle 50 and the handle 22 are both provided with an anti-slip sleeve 27 to increase the friction between the hand and the pull handle 50 and the handle 22, a material guide frame 28 is fixedly connected to the oil-water separation plate 4, the material guide frame 28 is used to guide the liquid falling on the oil-water separation plate 4, so that the liquid gathers to the middle of the oil-water separation plate 4.

[0028] When it is necessary to separate oil and water from the range hood, connect the butt joint 10 to the oil collecting box of the range hood, then start the electric slide 13, which drives the electric slider 14 to slide to the left. The electric slider 14 drives the piston rod 11 to slide to the left in the piston box 7 through the connecting plate 12. At this time, under the action of the one-way drain pipe 8 on the right side of the piston box 7, a pressure difference is formed between the right side of the piston box 7 and the outside world, so that the oil-water mixture in the oil collecting box enters the piston box 7 through the butt joint 10 and the one-way liquid extraction pipe 9 on the right side. Then control the electric slide 13 to drive the electric slider 14 to slide to the right. Under the action of the one-way drain pipe 8 on the left side of the piston box 7, a pressure difference is formed between the left side of the piston box 7 and the outside world, so that the oil-water mixture in the oil collecting box enters the piston box 7 through the butt joint 10 and the one-way liquid extraction pipe 9 on the right side. The oil-water mixture in the box enters the piston box 7 through the docking pipe 10 and the one-way liquid extraction pipe 9 on the left. At the same time, the piston rod 11 squeezes the oil on the right side of the piston box 7, so that the oil-water mixture on the right side of the piston box 7 enters the separation box 1 through the one-way liquid discharge pipe 8 on the right. In this way, the electric slide rail 13 is controlled to drive the electric slider 14 to move back and forth, so that the oil-water mixture is drawn into the separation box 1, and the sieve plate 3 filters the residue in the oil-water mixture. The filtered oil-water mixture falls into the oil-water separation plate 4, and the oil-water separation plate 4 filters the oil-water mixture so that water remains on the oil-water separation plate 4, and the oil falls into the collection frame 5, thereby realizing oil-water separation. After collection, the collection frame 5 can be taken out.

[0029] Example 2: Based on Example 1, refer to Figure 6 and Figure 7 As shown, it also includes a drive motor 15, a screw rod 16, a sliding plate 17, a scraper 18, a connecting rod 19, a return spring 20, a slag collecting frame 21 and a handle 22. The drive motor 15 is installed inside the separation box 1 by bolt connection. The output shaft of the drive motor 15 is connected to the screw rod 16 through a coupling. The screw rod 16 is rotatably connected to one side of the separation box 1. A sliding plate 17 is slidably provided inside the separation box 1. The sliding plate 17 is threadedly connected to the screw rod 16. A plurality of connecting rods 19 are slidably provided on the sliding plate 17. The lower ends of the plurality of connecting rods 19 are commonly connected to the scraper 18. The scraper 18 is in contact with the screen plate 3. A return spring 20 is sleeved on the connecting rod 19. The two ends of the return spring 20 are respectively connected to the sliding plate 17 and the scraper 18. Two slag collecting frames 21 are slidably provided on the front side of the separation box 1. The front side of the slag collecting frame 21 is fixedly connected with a handle 22.

[0030] By starting the drive motor 15, the drive motor 15 drives the screw rod 16 to rotate, and the rotation of the screw rod 16 drives the sliding plate 17, the scraper 18, the connecting rod 19 and the return spring 20 to move to the left. The scraper 18 contacts the sieve plate 3, so that the sieve plate 3 squeezes the scraper 18 and drives the connecting rod 19 to slide upward. The scraper 18 compresses the return spring 20 and deforms it. Therefore, under the action of the return spring 20, the scraper 18 is close to the sieve plate 3, so that the scraper 18 can scrape off the residue on the sieve plate 3. The residue then falls into the residue collecting frame 21 through the separation box 1 for centralized recovery, so as to avoid the sieve plate 3 being affected during filtration. A bellows 29 is provided on the connecting rod 19, and the bellows 29 covers the return spring 20, thereby protecting the return spring 20 and preventing oil from condensing on the return spring 20.

[0031] See Figures 8-10 As shown, it also includes a refrigeration module 23, a circulation pipe 24 and a contact plate 25. The refrigeration module 23 is installed on the rear side of the separation box 1. Two circulation pipes 24 are connected to the left and right sides of the refrigeration module 23. A contact plate 25 is fixedly connected to the inside of the separation box 1. The contact plate 25 is in contact with the collection frame 5, and the circulation pipe 24 is wound around the contact plate 25. A sealing ring 26 is provided at the joint of the circulation pipe 24. The sealing ring 26 increases the sealing of the circulation pipe 24 to prevent the coolant in the circulation pipe 24 from leaking.

[0032] After the oil falls into the collection frame 5, the refrigeration module 23 is started to circulate the coolant in the circulation pipe 24. The contact plate 25 conducts the heat of the oil in the collection frame 5, and then the heat on the contact plate 25 is taken away through the circulation pipe 24, so that the temperature of the oil in the collection frame 5 drops, and the oil condenses in the collection frame 5, thereby facilitating the recovery and utilization of the oil.
