This design can recycle the filter 14 to avoid the same filter 14 being repeatedly used after cleaning, resulting in a reduction in the practical life of the filter 14. In addition, the filter 14 is frequently used, and it is difficult to clean the grease and impurities on its surface. By soaking the filter 14 in the solution, the filter 14 can be cleaned more comprehensively, so that the separation and filtration effect is better.

[0035] The power part includes a gear ring 2; a gear ring 2 is fixedly connected to the fixed disk 12 at the proximal end of the motor 15, and a first shaft is rotatably connected to the side wall of the fixed disk 12, a first gear 21 is fixedly connected to the first shaft, and the first gear 21 is meshed with the inside of the gear ring 2, and a synchronous wheel 22 is fixedly connected to the rotating rod 16 and the first shaft, and a pair of the synchronous wheels 22 are driven by a synchronous belt 23, and the diameter of the synchronous wheel 22 on the first shaft is larger than the diameter of the synchronous wheel 22 on the rotating rod 16; when working, the motor 15 drives the proximal fixed disk 12 when it rotates The gear ring 2 on the rotating rod 16 rotates, and the gear ring 2 meshes with the first gear 21, so that the first shaft rotates. The rotating rod 16 and the first shaft are equipped with a synchronous wheel 22 and are driven by a synchronous belt 23. The diameter of the synchronous wheel 22 on the first shaft is larger than the diameter of the synchronous wheel 22 on the rotating rod 16, so that the rotation speed is changed, thereby driving the filter 14 to rotate slowly, and the rotating rod 16 rotates quickly, so that when the filter 14 is ready to start rotating, the oil collecting box 192 is pushed in advance to avoid the oil collecting box 192 being set below the filter 14 to collect grease and affect the rotation of the filter 14.

[0036] The driving member includes a sliding block 31; the side wall of the oil collecting box 192 is fixedly connected to the sliding block 31 through the L plate 3, and a pair of opposite side walls of the fixed plate 12 are provided with sliding grooves 32, and the two ends of the sliding block 31 are slidably connected in the sliding grooves 32, and the side walls of the sliding grooves 32 are fixedly connected to the side walls of the sliding block 31 through springs; the side wall of the sliding block 31 is provided with an arc surface, and a pair of driving blocks 33 are fixedly connected to the rotating rod 16, and the positions of the driving blocks 33 and the arc surface correspond; the oil collecting box 192 is provided with a guide groove, and the side wall of the oil collecting box 192 is fixedly connected to the oil delivery pipe through the oil delivery groove, and the oil delivery pipe runs through the fixed plate 12; when working, the driving block 33 is driven to rotate by the rotating rod 16, and when the driving block 33 is aligned with the sliding block 31 When the arc surface contacts, the sliding block 31 is pushed to slide in the sliding groove 32, compressing the spring. When the driving block 33 leaves the arc surface, the spring is reset, the sliding block 31 slides in the opposite direction, and contacts the inner wall of the filter 14 to scrape off impurities and grease, so that the oil collecting box 192 reciprocates between the fixed disks 12. When the used filter 14 rotates to the solution in the arc-shaped support box 191, the new filter 14 rotates to the connecting groove. At this time, the motor 15 stops running, and the driving block 33 is located near the proximal end of the sliding block 31, preparing for the next cycle of pre-pushing the sliding block 31 and the oil collecting box 192. The oil collecting box 192 collects the grease separated during the filtration process and discharges the grease through the oil pipe. The guide groove guides the flow of grease.

[0037] The adsorption unit includes a fan 8, and the side wall of the fixed disk 12 near the motor 15 is fixedly connected to the fan 8. The air inlet end of the fan 8 is fixedly connected to a receiving cover 81 through a connecting pipe, and the receiving cover 81 corresponds to the position of the connecting groove, and the outlet end of the fan 8 is connected to the adsorption box 11 through a conduit.

The adsorption material in the adsorption box 11 further adsorbs impurities and odors in the oil smoke to purify the oil smoke.

[0038] Embodiment 2

[0039] like Figures 1 to 12 As shown, the F ring 13 at the far end of the motor 15 is rotatably connected to the collection box 4, and the collection box 4 is fixedly connected to the inner wall of the box body 1, one end of the arc-shaped support box 191 is rotatably connected to the F ring 13, and the other end is open and communicated with the collection box 4; the side wall of the arc-shaped support box 191 is rotatably connected to the reciprocating screw 41 through the first groove, the end of the reciprocating screw 41 is fixedly connected to the second gear 42, and the second gear 42 is meshed with the outside of the gear ring 2; the reciprocating screw 41 is threadedly connected to a push block 43, and the push block 43 is adapted to the arc-shaped support box 191; a pair of guide grooves 44 are provided on the inner surface of the arc-shaped support box 191, and a pair of guide grooves 44 are fixedly connected to the bottom of the push block 43 The guide slider 45 is slidably connected in the guide slide groove 44; one end of the rotating rod 16 is rotatably connected to the side wall of the collecting box 4; when working, the motor 15 drives the gear ring 2 to rotate, and the outer part of the gear ring 2 is engaged with the second gear 42, so that the reciprocating screw 41 rotates, and the push block 43 is threadedly connected to the reciprocating screw 41. When the reciprocating screw 41 rotates, the push block 43 makes a reciprocating linear motion along the inner surface of the arc-shaped support box 191, and the guide slider 45 slides in the guide slide groove 44 to ensure the stability of the movement of the push block 43. One end of the arc-shaped support box 191 is rotatably connected to the F ring, and the other end opening is connected to the collecting box 4, so that the filtered oil impurities can be pushed into the collecting box 4 through the push block 43.

[0040] A pair of fixed blocks 5 are fixedly connected to the inner surface of the arc-shaped support box 191, and parallelogram grooves 51 are provided on the opposite side walls of the pair of fixed blocks 5, and lifting grooves are provided on the diagonal side walls of the parallelogram grooves 51, and lifting blocks 52 are fixedly connected to the lifting grooves through springs, and the cross-section of the lifting blocks 52 is a right-angled trapezoid; a lifting plate 53 is slidably connected to the top of the push block 43 through a vertical groove, and guide rods 54 are fixedly connected to the side walls of the lifting plate 53 at both ends, and a pair of guide rods 54 are slidably connected in the parallelogram grooves 51; a spacing groove is provided at the bottom of the push block 43; when working, the push block 43 reciprocates under the drive of the reciprocating screw 41, and the purpose of providing the spacing groove at the bottom of the push block 43 is to prevent the push block 43 from contacting the arc-shaped support box 191, and the guide rods 54 on the lifting plate 53 slide in the parallelogram grooves 51. When the guide rods 54 are located in the parallelogram grooves, the lifting plate 53 is in a state of being in contact with the arc-shaped support box 191. When the lower end of the parallelogram groove 51 slides, the bottom of the lifting plate 53 contacts the arc-shaped support box 191. When the lifting plate 53 drives the guide rod 54 to slide to the inclined surface of the lifting block 52, the lifting block 52 and its bottom or top spring are squeezed, and then the guide rod 54 slides to the plane of the lifting block 52 and is lifted up by the lifting block 52. Because of the shape of the parallelogram groove 51, under the reverse drive of the lifting plate 53, the guide rod 54 automatically slides to the upper end of the parallelogram groove 51 and slides in the opposite direction. At this time, the lifting plate 53 rises and does not contact the bottom of the arc-shaped support box 191. Grease and impurities remain and nodule in the arc-shaped support box 191. This design allows the lifting plate 53 to push impurities from one end of the arc-shaped support box 191 into the collection box 4, and avoids pushing impurities from one end of the collection box 4 into the arc-shaped support box 191 at one end of the motor 15, causing the problem of being difficult to remove.

[0041] Embodiment 3

[0042] like Figures 1 to 12 As shown, a group of fixing columns 6 are fixedly connected between the opposite side walls at both ends of a pair of F rings 13, and the fixing block 5 passes through the filter screen 14. The top and bottom of the filter screen 14 are fixedly connected to the ring wall of the F ring 13 through a spring, and the spring is located outside the fixing column 6; a folding plate 61 is rotatably connected between a pair of fixed disks 12 through a second rod, and one end of the folding plate 61 is rotatably connected to the L plate 3 through a third rod between the opposite side walls, and the other end corresponds to the center of the filter screen 14; when working, when the sliding block 31 is pushed to move by the driving block 33, the L plate 3 is also driven to move, and the folding plate 61 is driven by the L plate 3 to rotate with the second rod as the axis. At this time, the filter screen 14 can be auxiliary shaken during the rotation of the folding plate 61, so that the oil impurities attached to the filter screen 14 are more likely to fall into the arc-shaped support box 191, and the impurities are prevented from being attached to the filter screen 14 after being decomposed by the solution, causing the problem of unclean cleaning affecting the filtering effect.

[0043] The rotating rod 16 is fixed with a fixing plate 7, and one end of the fixing plate 7 is in contact with the inner wall of the collecting box 4. The collecting box 4 is fixed with an L-shaped box 71 through an open groove. The side wall of the L-shaped box 71 is hinged with a cleaning door 72. A bending plate 73 is fixed between the opposite side walls of the L-shaped box 71. The side walls of both ends of the bending plate 73 are provided with flow grooves. The side wall of the box body 1 is provided with a through groove, and the position of the through groove and the cleaning door 72 corresponds to each other; the second column 18 is rotatably connected with a drying roller 74; when working, when the rotating rod 16 is rotated, the fixing plate 7 moves with the rotating rod 16 rotates, and the liquid and impurities in the collecting box 4 are driven into the L-shaped box 71. Because the length of the L-shaped box 71 from the rotating rod 16 is greater than the radius of the collecting box 4, under the centrifugal force, the impurities are thrown into the L-shaped box 71, and the liquid flows into the collecting box 4 along the circulation groove. The impurities stay on the bending plate 73, and the impurities can be cleaned regularly by opening the cleaning door 72. This design prevents impurities from accumulating. The second column 18 can not only play the role of fixing the fixed plate 12, but also the drying roller 74 rotatably connected thereto can wipe off the moisture on the surface of the soaked filter screen 14.

[0044] Working principle: The oil smoke is driven to enter from the connecting groove through the adsorption unit, and the filter 14 filters the oil smoke and the impurities attached thereto. The motor 15 drives the rotating rod 16 to rotate, and drives the F ring 13 and the filter 14 to rotate slowly through the power part. The fixed disk 12 at the proximal end of the motor 15 is fixed by the first column 17, and the pair of fixed disks 12 are fixed by the second column 18. The pair of F rings 13 are fixed by the driving rod 19, so that the pair of F rings 13 rotate synchronously; when the device stops working, the motor 15 is started to drive the filter 14 to rotate, and the used filter 14 rotates into the arc-shaped support box 191. The solution in the arc-shaped support box 191 soaks and dissolves the filter 14, so that the grease and impurities remaining on the surface are decomposed and fall into the arc-shaped support box 191. At the same time, the rotating rod 16 rotates quickly to push the oil collecting box 192 to a position away from the bottom end of the filter screen 14 in advance to avoid affecting the rotation of the filter screen 14. This design can recycle the filter screen 14 to avoid the same filter screen 14 being repeatedly used after cleaning, which leads to a reduction in the practical life of the filter screen 14. In addition, the filter screen 14 is frequently used, and it is difficult to clean the grease and impurities on its surface. By immersing the filter screen 14 in the solution, the filter screen 14 can be cleaned more comprehensively, so that the separation and filtration effect is better. When the motor 15 rotates, it drives the toothed ring 2 on the proximal fixed disk 12 to rotate, and the toothed ring 2 is meshed with the first gear 21, so that the first shaft rotates. The rotating rod 16 and the first shaft are equipped with a synchronous wheel 22 and are driven by a synchronous belt 23, and the synchronous wheel 2 on the first shaft is 2 is larger than the diameter of the synchronous wheel 22 on the rotating rod 16, realizing the change of the rotation speed, thereby driving the filter 14 to rotate slowly, and the rotating rod 16 rotates quickly, so that when the filter 14 is ready to start rotating, the oil collecting box 192 is pushed in advance to prevent the oil collecting box 192 from being set below the filter 14 to collect grease and affect the rotation of the filter 14. The driving block 33 is driven to rotate by the rotating rod 16. When the driving block 33 contacts the arc surface on the sliding block 31, the sliding block 31 is pushed to slide in the sliding groove 32 to compress the spring. When the driving block 33 leaves the arc surface, the spring is reset, and the sliding block 31 slides in the opposite direction and contacts the inner wall of the filter 14 to scrape off impurities and grease, so that the oil collecting box 192 reciprocates between the fixed disk 12. When the used filter 14 When the solution in the arc-shaped support box 191 is rotated, the new filter screen 14 rotates to the connecting groove. At this time, the motor 15 stops running, and the driving block 33 is located near the proximal end of the sliding block 31, preparing for the next cycle of pre-pushing the sliding block 31 and the oil collecting box 192. The oil collecting box 192 collects the grease separated during the filtration process and discharges the grease through the oil pipe. The guide groove guides the flow of grease. The motor 15 drives the gear ring 2 to rotate, and the outer part of the gear ring 2 meshes with the second gear 42 to rotate the reciprocating screw 41. The push block 43 is threadedly connected to the reciprocating screw 41. When the reciprocating screw 41 rotates, the push block 43 makes a reciprocating linear motion along the inner surface of the arc-shaped support box 191, and the guide slider 45 slides in the guide groove 44 to ensure the stability of the movement of the push block 43.One end of the arc-shaped support box 191 is rotatably connected to the F ring, and the other end opening is communicated with the collecting box 4, so that the filtered oil impurities can be pushed into the collecting box 4 through the push block 43. The push block 43 reciprocates under the drive of the reciprocating screw 41. The purpose of the spacing groove at the bottom of the push block 43 is to prevent the push block 43 from contacting the arc-shaped support box 191. The guide rod 54 on the lifting plate 53 slides in the parallelogram groove 51. When the guide rod 54 slides at the lower end of the parallelogram groove 51, the bottom of the lifting plate 53 contacts the arc-shaped support box 191. When the lifting plate 53 drives the guide rod 54 to slide to the inclined surface of the lifting block 52, the lifting block 52 and its bottom or top are squeezed. Spring, then the guide rod 54 slides to the plane of the lifting block 52, and is then lifted up by the lifting block 52. Because of the shape of the parallelogram groove 51, under the reverse drive of the lifting plate 53, the guide rod 54 automatically slides to the upper end of the parallelogram groove 51 and slides in the opposite direction. At this time, the lifting plate 53 rises and does not contact the bottom of the arc-shaped support box 191. Grease and impurities remain and nodule in the arc-shaped support box 191. This design allows the lifting plate 53 to push impurities from one end of the arc-shaped support box 191 into the collection box 4, and avoids the problem of pushing impurities from one end of the collection box 4 into the arc-shaped support box 191 at one end of the motor 15, causing a problem of being difficult to remove. By driving the block 33 When the sliding block 31 is pushed to move, the L plate 3 is also driven to move, and the folding plate 61 is driven by the L plate 3 to rotate with the second rod as the axis. At this time, the filter screen 14 can be auxiliary shaken during the rotation of the folding plate 61, so that the oil impurities attached to the filter screen 14 are more likely to fall into the arc-shaped support box 191, and the impurities are prevented from being attached to the filter screen 14 after being decomposed by the solution, causing the problem of unclean cleaning affecting the filtering effect. When the rotating rod 16 rotates, the fixed plate 7 rotates with the rotating rod 16, and the liquid and impurities in the collection box 4 are driven into the L-shaped box 71. Because the length of the L-shaped box 71 from the rotating rod 16 is greater than the radius of the collection box 4, under the centrifugal force, the impurities After being thrown to the L-shaped box 71, the liquid flows into the collection box 4 along the flow groove, and the impurities stay on the bending plate 73. The impurities can be cleaned by opening the cleaning door 72 regularly. This design prevents the accumulation of impurities. The second column 18 can not only play the role of fixing the fixed plate 12, but also the drying roller 74 connected thereto can wipe off the moisture on the surface of the soaked filter 14. When the fan 8 is working, the oil fume initially filtered by the filter 14 is sucked from the connecting groove through the receiving cover 81. The oil fume enters the fan 8 through the connecting pipe, and then enters the adsorption box 11 through the conduit. The adsorption material in the adsorption box 11 further adsorbs the impurities and odors in the oil fume to purify the oil fume.
