The inner wall of the mounting member 2 is fixedly connected to a filter screen 10, and the outside of the mounting member 2 is fixedly connected to a connecting pipe 3, and the other end of the connecting pipe 3 is fixedly connected to a connecting pipe 4, and the other end of the connecting pipe 4 is fixedly connected to a movable pipe 5, and the inner wall of the movable pipe 5 is slidably connected to a filter screen 6, and a disassembly component is installed inside the movable pipe 5, and the disassembly component is used to disassemble the filter screen 6.

[0032] Furthermore, the blower inside the connecting pipe 3 is first started, and the oil smoke enters the equipment through the air inlet pipe 1, and then enters the mounting part 2. At this time, the oil particles and solid particles in the oil smoke are filtered through the filter screen 10, and the motor 9 is started. The motor 9 drives the bevel gear 12 to rotate at the same time through the transmission shaft 11, and then the bevel gear 13 is rotated at the same time under the meshing action of the bevel gear 12, and then the bevel gear 13 drives the limit rod 14 to rotate at the same time, and then drives the eccentric wheel 15 to rotate. At the same time, the eccentric wheel 15 drives the protective rod 16 to rotate. At this time, the protective rod 16 drives the brush 18 to move left and right along the surface of the filter screen 10 through the fixing block 17, and the surface of the filter screen 10 is cleaned by the brush 18 to reduce the possibility of grease particles agglomerating and solidifying on the surface of the filter screen 10. This helps to extend the service life of the filter screen 10.

[0033] Reference Figure 2 , Figure 3 and Figure 4 The disassembly assembly includes two pull rods 7, the outside of the pull rods 7 is slidably connected to the outside of the movable tube 5, the outside of the pull rods 7 is sleeved with a spring 20, the other end of the pull rods 7 is fixedly connected to a baffle 22, the other side of the baffle 22 is fixedly connected to a clamping block 23, the inside of the movable tube 5 is provided with two internal grooves 21, the outside of the filter screen 6 is provided with two clamping grooves 24, and the outside of the movable tube 5 is fixedly connected to an outlet pipe 8; one end of the spring 20 is fixedly connected to the inner wall of the internal groove 21, and the other end of the spring 20 is fixedly connected to a side of the baffle 22 away from the clamping block 23; the longitudinal section of the baffle 22 is square, and the outside of the baffle 22 is slidably connected to the inner wall of the internal groove 21; the shape of the clamping block 23 matches the clamping groove 24, and the clamping block 23 and the clamping groove 24 are plug-in fit.

[0034] Furthermore, in addition, the oil smoke is filtered for the second time through the filter 6, and the bacteria, harmful substances and other pollutants in the oil smoke are carefully filtered through the filter 6. When it is necessary to remove the filter 6, the two pull rods 7 are pulled outward at the same time, and then the pull rod 7 drives the block 23 to slide at the same time through the baffle 22 until the block 23 is completely retracted into the interior of the internal groove 21, and then the filter 6 is pulled upward to separate the filter 6 from the movable tube 5, that is, the removal of the filter 6 is completed. When it is necessary to install the filter 6, the pull rod 7 is pulled, and the above steps are repeated. At this time, the spring 20 is in a compressed state, and the outer part of the filter 6 is fitted with the inner wall of the movable tube 5. The pull rod 7 is released. Under the elastic force of the spring 20, the block 23 is reset, and then the block 23 is driven to move. The block 23 is inserted into the interior of the card slot 24, and the installation of the filter 6 is completed. By disassembling the filter 6, the filter 6 can be cleaned more thoroughly, which effectively prevents the accumulation of pollutants and clogging of the filter 6, and is beneficial to extending the service life of the filter 6; the spring 20 is limited by the internal groove 21 and the baffle 22. When the pull rod 7 is pulled, the force on the spring 20 is more uniform, and the service life of the spring 20 is delayed; the baffle 22 slides along the inner wall of the internal groove 21 through the pull rod 7, which effectively prevents the baffle 22 from shaking, and further increases the reliability of the baffle 22; the card block 23 is inserted into the card slot 24 to fix the filter 6, which ensures the stability of the filter 6 and further improves the filtering efficiency of the filter 6.

[0035] Reference Figure 1 , Figure 3 and Figure 5 The outer side of bevel gear 12 is meshedly connected with the outer side of bevel gear 2 13 at the corresponding position, and the end of transmission shaft 11 away from motor 9 is rotatably connected with the inner wall of support member 19; the outer side of protective rod 16 is slidably connected with the inner wall of fixed block 17, and the outer side of brush 18 is slidably connected with the outer side of filter screen 2 10; the interior of intake pipe 1 is connected with mounting member 2, mounting member 2 is connected with the interior of connecting pipe 3, and the interior of connecting pipe 3 is fixedly connected with a blower.

[0036] Furthermore, the bevel gear 1 12 drives the bevel gear 2 13 to rotate, and then drives the limit rod 14 to rotate at the same time, and the transmission shaft 11 contacts the inner wall of the support member 19, thereby further improving the stability of the transmission shaft 11; the protective rod 16 is limited by the fixed block 17, so that the protective rod 16 drives the brush 18 to move left and right along the outer side of the fixed block 17 to clean the surface of the filter screen 2 10, thereby reducing the difficulty and frequency of subsequent cleaning; by starting the blower, the interior of the air intake pipe 1 and the mounting member 2 is in a negative pressure state, so that the oil smoke enters the interior of the mounting member 2 through the air intake pipe 1, thereby accelerating the oil smoke filtration efficiency.

[0037] Working principle: first, start the blower inside the connecting pipe 3, and then the oil smoke enters the equipment through the air intake pipe 1, and then enters the inside of the mounting part 2, and the grease particles and solid particles in the oil smoke are filtered through the filter screen 10, and the motor 9 is started. The motor 9 drives the transmission shaft 11 to rotate, and then drives the bevel gear 1 12 to rotate at the same time, and then the bevel gear 1 12 drives the bevel gear 2 13 to rotate at the same time through meshing, and then the bevel gear 2 13 drives the eccentric wheel 15 to rotate through the limiting rod 14. At the same time, the eccentric wheel 15 drives the protective rod 16 to rotate. At this time, under the limiting action of the fixed block 17, the protective rod 16 drives the brush 18 to move left and right along the surface of the filter screen 10, and the surface of the filter screen 10 is cleaned by the brush 18. In this way, the grease accumulated on the surface of the filter screen 10 can be effectively removed, the original filtering efficiency of the filter screen can be restored, and continuous and efficient filtering of oil smoke can be ensured.

[0038] In addition, the oil smoke is filtered twice by the filter 6, and the pollutants such as bacteria and harmful substances in the oil smoke are carefully filtered by the filter 6, and the filtered oil smoke is discharged through the exhaust pipe 8. When it is necessary to remove the filter 6, the two pull rods 7 are pulled outward at the same time, thereby driving the baffle 22 to slide along the inner wall of the internal groove 21, thereby driving the block 23 to slide at the same time until the block 23 is separated from the groove 24, and then the filter 6 is pulled upward to separate the filter 6 from the movable tube 5, that is, the removal of the filter 6 is completed. When it is necessary to install the filter 6, the pull rod 7 is pulled and the above steps are repeated. At this time, the spring 20 is in a compressed state, and the outer part of the filter 6 is fitted with the inner wall of the movable tube 5. The pull rod 7 is released. Under the elastic force of the spring 20, the block 23 is stuck into the inside of the groove 24, that is, the installation of the filter 6 is completed. By disassembling the filter 6, the filter 6 can be more thoroughly cleaned, and cross infection of bacteria can be effectively prevented.
