Detailed Implementation

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] Please see Figures 1 to 16As shown, the present invention provides a technical solution: an oily material purification range hood, comprising a control component 1, a pushing component 2, a drying component 3, a spraying component 4, a housing component 5, a sewage discharge component 6, a sealing component 8, and a cleaning component 9. The control component 1 includes two support plates 102, which are respectively fixedly connected to a first purification chamber 502 and a second purification chamber 503. Gears 105 are rotatably connected to the support plates 102, and two limit blocks 104 are fixedly connected to the gears 105. A lead screw 107 is also slidably connected to the support plates 102. 07 is threaded, and the lead screw gear 106 is threadedly connected to the lead screw 107. At the same time, the lead screw gear 106 meshes with the gear 105. The pushing assembly 2 includes four slide rods 204. The four slide rods 204 are fixedly connected in pairs to the right push plate 201 and the left push plate 202. The two slide rods 204 corresponding to the right push plate 201 or the left push plate 202 are slidably engaged with the first end of the same inclined plate 203. The second ends of the two inclined plates 203 are slidably connected to the corresponding first purification chamber 502 and second purification chamber 503, respectively. The right push plate 201 is slidably connected to the first cleaning box 5. 01. The left push plate 202 is slidably connected to the second cleaning chamber 504. A top block 605 is also fixedly connected to the inclined plate 203. The spray assembly 4 includes two cleaning pipes 402, which are respectively fixedly connected to the right push plate 201 and the left push plate 202. A cleaning pipe rear seal plate 403 is fixedly connected to the cleaning pipe 402. The two cleaning pipe rear seal plates 403 are slidably connected to the corresponding first purification chamber 502 and second purification chamber 503. Multiple cleaning nozzles 404 are fixedly connected to the cleaning pipe 402. A cleaning pipe front seal plate is fixedly connected to each cleaning pipe 402. Plate 405, two front sealing plates 405 of cleaning pipes are slidably connected to the corresponding first purification chamber 502 and second purification chamber 503 respectively. The cleaning component 9 includes a roller brush 903, a brush support rod 909 is rotatably connected to the roller brush 903, the brush support rod 909 is slidably connected to the cleaning support frame 901, the cleaning support frame 901 is fixedly connected to the inclined plate 203, a front sealing plate 803 is slidably connected to the cleaning support frame 901, and the first end of the cleaning spring 902 is fixedly connected to the cleaning support frame 901, and the second end is fixedly connected to the brush support rod 909.

[0039] A motor 101 is fixedly connected to the support plate 102. The first end of the lead screw 107 is rotatably connected to the right push plate 201, and the second end is rotatably connected to the left push plate 202. At the same time, the two ends of the lead screw 107 are rotatably connected to two push rods 303.

[0040] like Figure 5As shown, the motor 101 is connected to the gear 105 via the belt 103, transmitting the power of the motor 101. The gear 105 drives the lead screw gear 106 to rotate. At the same time, the limiting blocks 104 on both sides of the gear 105 limit the lead screw gear 106. Because the lead screw gear 106 is threadedly connected to the lead screw 107, when the lead screw gear 106 rotates, it drives the lead screw 107 to rotate. By controlling the forward and reverse rotation of the motor 101, the lead screw 107 can move left and right. The two ends of the lead screw 107 are rotatably connected to the right push plate 201 and the left push plate 202. Therefore, when the lead screw 107 moves left and right, it drives the right push plate 201 and the left push plate 202 to move left and right. At the same time, two push rods 303 are rotatably connected to the upper part of the lead screw 107 near the threaded ends. Therefore, when the lead screw 107 moves left and right, it also drives the push rods 303 to move left and right.

[0041] The pushing component 2 also includes a guide plate 205, which is fixedly connected to the top of the cleaning inlet of the first purification chamber 502 and the second purification chamber 503. The first end of the support spring 206 is fixedly connected to the left push plate 202, and the second end is fixedly connected to the inclined plate 203. The chamber slide 505 is fixedly connected inside the first purification chamber 502 and the second purification chamber 503.

[0042] like Figure 5 , Figure 8 and Figure 11 As shown, guide plate 205 is slidably connected to cleaning tank 501, and left push plate 202 is slidably connected to cleaning tank 504. When screw 107 moves to the right, right push plate 201 slides out of cleaning tank 501, while left push plate 202 slides in into cleaning tank 504. Similarly, when screw 107 moves to the left, right push plate 201 and left push plate 202 move in the opposite direction. Because slide rod 204 is slidably connected to the rear end of inclined plate 203, when right push plate 201 and left push plate 202 slide into cleaning tank 504, they push the inclined plate. 203 slides along the slide rail 505 into the first purification chamber 502 or the second purification chamber 503. When sliding inward, the inclined plate 203 is in an inclined state, and the slide rail 505 is also an inclined groove. Therefore, when the inclined plate 203 slides inward, it slides downward along the slide rod 204. At the same time, the bottom surface squeezes the support spring 206. When the right push plate 201 or the left push plate 202 slides outward, the inclined plate 203 gradually rises along the slide rod 204 as it is pulled out, and the support spring 206 also rises accordingly, playing a supporting role.

[0043] The air-drying assembly 3 includes an air vent sealing plate 302, which is fixedly connected to the push rod 303 and slidably connected to the support groove 309. The air vent sealing plate 302 is fixedly connected to a first air outlet 301 and a second air outlet 304. The first end of the second air supply pipe 305 is fixedly connected to a second air intake pipe 508, and the second end is fixedly connected to a first air-drying inlet 311. The first air-drying inlet 311 is fixedly connected to a first purification chamber 502. The first end of the No. 1 air supply pipe 306 is fixedly connected to the No. 1 air intake pipe 507, and the second end is fixedly connected to the No. 2 air drying inlet 313. The No. 2 air drying inlet 313 is fixed to the No. 2 purification chamber 503. The sliding partition 312 is slidably connected to the No. 1 air drying inlet 311 and the No. 2 air drying inlet 313. The sliding partition 312 is fixedly connected to the pull rod 310. The pull rod 310 is slidably connected to the No. 1 air drying inlet 311. The pull rod 310 is fixedly connected to the guide plate 205.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, push rod 303 is rotatably connected to lead screw 107, and one side of air vent sealing plate 302 is fixedly connected to push rod 303. The rod connected to push rod 303 is slidably connected to support groove 309. The two ends of support groove 309 are fixedly connected to cleaning liquid tanks 401 on both sides. At the same time, inclined plate 203 slides against the upper surfaces of first suction pipe 507 and second suction pipe 508. First air outlet 301 and second air outlet 304 are also fixedly connected to the upper surface of inclined plate 203. Exhaust pipes are connected to first air outlet 301 and second air outlet 304. Therefore, when lead screw 107 moves left and right, push rod 303 drives air vent sealing plate 302 to move along support groove 309. Figure 6 As a reference, when the lead screw 107 moves to the right, it drives the air vent sealing plate 302 to move to the right. The air vent sealing plate 302 moves to the right, thereby sealing the first air intake pipe 507. The second air outlet 304 is directly opposite the second air intake pipe 508.

[0045] Two exhaust fans 307 are fixedly installed on the first suction pipe 507 and the second suction pipe 508, respectively, directly above the spray assembly and below the connection port of the second air supply pipe 305 and the first air supply pipe 306. The first end of the second air supply pipe 305 is fixedly connected to the second suction pipe 508, with the connection port located above the exhaust fan 307 and below the air outlet of the second suction pipe 508. The other end of the second air supply pipe 305 is fixedly connected to the first drying air inlet 311. The first drying air inlet 311 is fixedly installed in the first purification chamber 502, below the filter screen 308 and above the chamber slide groove 505. The first end of the first air supply pipe 306 is fixedly connected to the first suction pipe 507. At a position parallel to the second air supply pipe 305 on the second suction pipe 508, the second end of the first air supply pipe 306 is fixedly connected to the second air drying inlet 313. The second air drying inlet 313 is installed on the second purification chamber 503, and its installation position is parallel to the first air drying inlet 311. The first air drying inlet 311 and the second air drying inlet 313 are slidably connected to a sliding partition 312. A pull rod 310 is fixedly connected to one end of the sliding partition 312 near the first air drying inlet 311. The pull rod 310 is fixedly connected to the right push plate 201, and the connection position is located on the part of the right push plate 201 that extends out of the first cleaning box 501. The right push plate 201 will slide with the left and right movement of the lead screw 107, so that when... Figure 3 To ensure timely drying, if the filter 308 inside the second purification chamber 503 needs to be dried, the screw 107 moves to the left, causing the right push plate 201 and push rod 303 to move to the left. The right push plate 201 moving to the left, in turn, drives the sliding partition 312 to the left via the pull rod 310. The sliding partition 312 moving to the left opens the connection between the second drying air inlet 313 and the second purification chamber 503. Simultaneously, the sliding partition 312 seals the connection between the first drying air inlet 311 and the first purification chamber 502. The push rod 303 then moves... The left side drives the air vent sealing plate 302 to seal the first air intake pipe 507 to the left, while the second air outlet 304 aligns with the second air intake pipe 508. At this time, the airflow from the first air intake pipe 507 enters the first air supply pipe 306. Because the sliding partition 312 slides to the left with the right push plate 201, the airflow directly enters the second purification chamber 503, dries the filter screen 308 inside the second purification chamber 503, and finally exits from the second air outlet 304 through the second air intake pipe 508.

[0046] The spray assembly 4 also includes a cleaning fluid tank 401, which is equipped with a water pump. There are two cleaning fluid tanks 401, which are fixedly connected to the four support frames of the first cleaning tank 501 and the second cleaning tank 504, respectively. A water tank sealing slider 406 is slidably connected to the bottom of the cleaning fluid tank 401. The water tank sealing slider 406 is slidably connected to the sealing slider groove 408. The first end of the sealing slider spring 407 is fixedly connected to the water tank sealing slider 406, and the second end is fixedly connected to the sealing slider groove 408. There are two sealing slider grooves 408, which are fixedly fixed to the first cleaning tank 501 and the second cleaning tank 504, respectively, and located below the cleaning fluid tank 401.

[0047] like Figure 1 , Figure 8 , Figure 9 and Figure 12 As shown, two cleaning fluid tanks 401 are respectively mounted on the upper surface support frame of cleaning tank 501 and cleaning tank 504. Two cleaning pipes 402 are fixedly connected to the right push plate 201 and the left push plate 202. Therefore, when the left push plate 202 and the right push plate 201 move, the cleaning pipes 402 will also move accordingly. When the right push plate 201 pushes inward, the cleaning pipe 402 portion, with the cleaning pipe rear sealing plate 403 near the cleaning nozzle 404 as the reference, will be gradually pushed in, finally reaching the interior of the first purification chamber 502 or the second purification chamber 503, located directly above the filter screen 308. At the same time, the cleaning pipe rear sealing plate 403 seals the inlet of the cleaning pipe 402 to prevent gas from leaking out. When the cleaning pipe 402 is pushed inward with the right push plate 201 or the left push plate 202, the interface end of the cleaning pipe 402 moves along the first cleaning tank 501 or the second cleaning tank. The groove on the top plate of 504 gradually moves inward until the pipe opening contacts the water tank sealing slider 406, pushing the water tank sealing slider 406 to move along the sealing slider groove 408, while squeezing the sealing slider spring 407, gradually aligning with the outlet of the cleaning fluid tank 401. After the spraying work is completed, it is pulled outward by sliding the right push plate 201 or the left push plate 202 until the front sealing plate 405 of the cleaning pipe seals the inlet. At the same time, the cleaning pipe 402 slides outward with the right push plate 201 or the left push plate 202, and the inlet of the cleaning pipe 402 gradually separates from the water pipe below the cleaning fluid tank 401. The water tank sealing slider 406 returns to its original position along the sealing slider groove 408 through the sealing slider spring 407, resealing the outlet below the cleaning fluid tank 401, preventing the cleaning fluid in the cleaning fluid tank 401 from flowing out due to damage to the water valve below the cleaning fluid tank 401.

[0048] The sewage discharge assembly 6 includes a sewage discharge pipe 601, which is fixedly connected to a sewage discharge trough 602. The sewage discharge trough 602 is fixedly connected to an air inlet 506. There are two flip-up partitions 603, which rotatably connect the first purification chamber 502 and the second purification chamber 503. The first end of the torsion spring 604 is fixedly connected to the sewage discharge trough 602, and the second end of the torsion spring 604 is fixedly connected to the flip-up partition 603.

[0049] like Figure 8 , Figure 9 , Figure 10 and Figure 14 As shown, there are two top blocks 605, which are fixedly connected to the ends of the two inclined plates 203 near the sewage discharge component 6. There are two flip-up partitions 603, which are rotatably connected to the sewage outlets of the first purification chamber 502 and the second purification chamber 503, respectively. The first end of the torsion spring 604 is fixedly connected to the inner side of the flip-up partition 603, and the second end of the torsion spring 604 is fixedly connected to the top plate of the sewage discharge trough 602. The sewage discharge trough 602 is fixedly connected to the lowest point in the middle of the first purification chamber 502 and the second purification chamber 503. The sewage discharge pipe 601 is fixedly connected to the groove opening of the bottom plate of the sewage discharge trough 602. Because the inclined plate 203 will move with the right push plate 2 When the left push plate 202 moves, the inclined plate 203 is pushed into the purification chamber. The top block 605 installed at the end of the inclined plate 203 near the sewage discharge component 6 contacts the flip partition 603. The inclined plate 203 continues to push the top block 605, which pushes the flip partition 603 to rotate and lift, and compresses the torsion spring 604. At this time, the sewage can flow into the sewage discharge tank 602 through the inclined plate 203 and be discharged to the designated location through the sewage discharge pipe 601. When the cleaning is finished, the inclined plate 203 is pulled out, the top block 605 is no longer in contact with the flip partition 603, and the flip partition 603 is reset by the torsion spring 604, resealing the sewage discharge port.

[0050] The sealing assembly 8 includes a rear sealing arc plate 802, a rear sealing plate 801 slidably connected to the rear sealing arc plate 802, a rear sealing spring 804 with its first end fixedly connected to the rear sealing arc plate 802 and its second end fixedly connected to the rear sealing plate 801, a front sealing plate 803 slidably connected to a cleaning support frame 901, a front sealing spring 805 with its first end fixedly connected to the cleaning support frame 901 and its second end fixedly connected to the front sealing plate 803.

[0051] like Figure 8 , Figure 9 and Figure 13As shown, the rear sealing plate 801 is fixed on the inclined plate 203. The upper center of the rear sealing plate 801 has a groove, which faces the rear sealing plate 403 of the cleaning pipe. The groove's width is equal to that of the rear sealing plate 403. A rear sealing spring 804 is installed inside the groove. The first end of the rear sealing spring 804 is fixedly connected to the bottom of the groove, and the second end is fixedly connected to the rear sealing arc plate 802. The rear sealing arc plate 802 is slidably connected to the rear sealing plate 801. A cleaning support frame 901 is fixedly connected to the inclined plate 203. The cleaning support frame 901 has a chute near the front end of the sewage discharge component. The bottom of the chute is fixedly connected to the first end of the front sealing spring 805, and the second end of the front sealing spring 805 is fixedly connected to the front sealing plate 803. The front sealing plate 803 is slidably connected to the cleaning support frame 901. Because the inclined plate 203 and the cleaning components installed on it will be pushed into the first purification chamber 502 and the second purification chamber 502... Inside purification chamber 503, there are inlets on purification chamber 1 502 and purification chamber 2 503. When the inclined plate 203 enters the purification chamber, the inlet is sealed by the rear sealing plate 801 and the rear sealing arc plate 802. At the same time, the front sealing plate 803 is lifted by the front sealing spring 805, opening the inlet of the inclined plate 203 to the sewage discharge component. When the inclined plate 203 is pulled out of the purification chamber, it will gradually rise as it is pulled out. The upper surface of the rear sealing arc plate 802 will contact the lower surface of the cleaning pipe rear sealing plate 403. At this time, the inclined plate 203 continues to move outward, and the cleaning pipe rear sealing plate 403 will compress the rear sealing spring 804 through the rear sealing arc plate 802. The rear sealing arc plate 802 will descend to avoid collision. At the same time, the front sealing plate 803 will gradually move outward with the inclined plate 203, compressing the front sealing spring 805 through the filter screen 308, causing the front sealing plate 803 to descend and finally seal the inlet.

[0052] The cleaning assembly 9 also includes a cleaning motor 905, which is fixedly connected to the inclined plate 203. A tensioning slide 906 is fixedly connected to the inclined plate 203. The tensioning slide 906 slidably connects a tensioning wheel 907 and a tensioning spring 908. The first end of the tensioning spring 908 is fixedly connected to the inclined plate 203, and the second end is fixedly connected to the tensioning wheel 907. An outer belt guide wheel 910 is fixedly connected to the inclined plate 203, and an inner belt guide wheel 911 is fixedly connected to the inclined plate 203.

[0053] like Figure 8 , Figure 9 and Figure 16As shown, a cleaning support frame 901 is fixedly mounted on an inclined plate 203. The cleaning support frame 901 has multiple parallel protrusions of different heights, each with a hole. Brush support rods 909 are slidably mounted on all protrusions. A cleaning spring 902 is fixedly connected to the upper surface of each protrusion of the cleaning support frame 901. The other end of the cleaning spring 902 is fixedly connected to the brush support rod 909. Roller brushes 903 are rotatably connected to the brush support rod 909. The number of roller brushes 903 corresponds to the number of protrusions on the cleaning support frame 901. The number of protrusions on the 01 side by side is the same, and the two ends are rotatably connected to the brush support rods 909 on both sides. The brush support rods 909 receive power from the cleaning motor 905 through the cleaning belt 904. The cleaning motor 905 is fixedly installed on the upper surface of the inclined plate 203 near the end of the slide rod 204. The cleaning belt 904 is first connected to the cleaning motor 905, then connected to the tension wheel 907, then connected to the outer belt guide wheel 910, and then connected to the inner belt guide wheel 911 through the hole on the rear sealing plate 801. Power is transmitted through the parallel roller brushes 903. The tensioning wheel 907 is slidably connected to the tensioning groove 906. When the cleaning assembly is pushed by the inclined plate 203, the entire cleaning assembly enters the first purification chamber 502 or the second purification chamber 503, located directly below the filter screen 308. During the advancement, the guide plate 205 contacts the roller brushes 903, compressing the cleaning spring 902, causing the roller brushes 903 and the brush support rod 909 to descend synchronously. After entering below the filter screen 308, they are lifted up by the cleaning spring 902 and pressed tightly against the filter screen 308. During the compression process, because the roller brushes 903 descend and enter in sequence, the cleaning belt 904 is stretched downwards, causing the tensioning wheel 907 to slide upwards along the tensioning groove 906, which plays a role in controlling the tension of the cleaning belt 904. At the same time, the outer belt guide wheel 910 and the inner belt guide wheel 911 guide the cleaning belt 904, reducing the friction of the cleaning belt 904 passing through the rear sealing plate 801.

[0054] The above-mentioned device is used to purify oily materials in a range hood and method. The method of use is as follows: Step 1: Start the exhaust fan 307 to draw oily fumes into the second purification chamber 503 through the air inlet 506. Then the oily fumes are purified by passing through the filter screen 308 in the second purification chamber 503.

[0055] Step 2: When the oil and dirt accumulate on the filter screen 308 in the second purification chamber 503 to the point that the purification efficiency is reduced, start the motor 101 to control the cleaning component and the spray component to enter the second purification chamber 503.

[0056] Step 3: After the cleaning components and spray components have fully entered the second purification chamber 503, start the cleaning water pump and cleaning motor 905 to clean the filter screen 308.

[0057] Step 4: When cleaning component 1 enters purification chamber 503, the cleaning component and spray component in purification chamber 502 exit. Purification chamber 502 begins to purify the oil fumes, while purification chamber 503 stops purifying. At the same time, the air outlet is switched by push rod 303 to dry the cleaned filter 308 in purification chamber 503.

[0058] Working principle: During operation, the exhaust fan 307 is started first. The oil fumes enter the second purification chamber 503 through the air inlet 506. The oil fumes are purified by the filter screen 308 installed inside the second purification chamber 503. After purification, the oil fumes enter the second suction pipe 508. Because the second suction pipe 508 is sealed by the air outlet sealing plate 302, the purified oil fumes enter the first purification chamber 502 through the second air supply pipe 305 installed on the second suction pipe 508. After entering the first purification chamber 502, the oil fumes pass through the filter screen 308 installed inside the first purification chamber 502 and enter the first suction pipe 507. Finally, they are discharged through the first air outlet 301.

[0059] When the filter screen 308 installed in the second purification chamber 503 becomes less efficient due to the accumulation of oil stains after prolonged operation, the start-up mechanism 101 is activated. 101 drives gear 105 via belt 103, which in turn drives lead screw gear 106, which in turn drives lead screw 107. Since lead screw 107 is threadedly connected to lead screw gear 106, and the limit blocks 104 on both sides of gear 105 limit lead screw gear 106, lead screw 107 can move left and right simultaneously as lead screw gear 106 rotates. Lead screw 107 moves towards the right push plate 201, simultaneously pushing the left push plate 202 into the second cleaning chamber 504. The left push plate 202 is equipped with the spray irrigation assembly 4. The right push plate 201 moves outward from the first cleaning chamber 501, while the left push plate 202... As the inclined plate 203 moves into the second cleaning chamber 504, it pushes the inclined plate 203 along the chamber slide 505 inside the second purification chamber 503. The inclined plate 203 eventually closes the opening of the second purification chamber 503 to the air inlet 506. As the inclined plate 203 moves inward, the end of the inclined plate 203 connected to the second cleaning chamber 504 also gradually slides down due to the sliding connection of the inclined plate 203 and the slide rod 204. The cleaning component 9 is installed on the inclined plate 203. During the pushing process, the guide plate 205 contacts the roller brush 903 and squeezes the cleaning spring 902 installed below the roller brush 903, causing the brush support rod 909 to slide down along the cleaning support frame 901, allowing the roller brush 903 to pass through the cleaning opening on the second purification chamber 503 and enter the second purification chamber 503.After the roller brush 903 enters the second purification chamber 503, the roller brush 903 slides upward on the brush support rod 909 via the cleaning spring 902, allowing the roller brush 903 to contact the filter screen 308. Simultaneously, as the inclined plate 203 is pushed into the second purification chamber 503, the top block 605 mounted on the inclined plate 203 gradually contacts the flip partition 603 on one side of the second purification chamber 503. The top block 605 causes the flip partition 603 to rotate counterclockwise, opening the drain port to the drain trough 602. During the pushing process, after the front sealing plate 803 enters the front sealing spring 805, the front sealing plate 803 is gradually lifted by the front sealing spring 805, and the rear sealing plate 801 seals the entrance to the cleaning component. When the component enters the second purification chamber 503, the inclined plate 203 pushes the cleaning pipe 402 to slide into the second purification chamber 503. After the cleaning pipe 402 slides inward, allowing the cleaning nozzle 404 installed on the cleaning pipe 402 to fully enter, the cleaning pipe rear sealing plate 403 installed on the cleaning pipe 402 seals the inlet of the cleaning nozzle 404 into the second purification chamber 503. As the left push plate 202 pushes inward, the water inlet of the cleaning pipe 402 gradually contacts the water tank sealing slider 406 along the sliding groove above the second cleaning chamber 504. The water tank sealing slider 406 compresses the sealing slider spring 407, causing the water tank sealing slider 406 to slide along the sealing slider groove 408. At the same time, the cleaning pipe 402 moves along with the water tank sealing slider. As the pump finally aligns with the outlet below the cleaning fluid tank 401, and the sealing slider 406 of the tank is aligned, the water pump below the cleaning fluid tank 401 starts, and the cleaning motor 905 starts simultaneously. The cleaning fluid inside the cleaning fluid tank 401 is sprayed from the cleaning nozzle 404 through the cleaning pipe 402 onto the filter screen 308 to dissolve the oil stains on the filter screen 308. At the same time, the cleaning motor 905 drives the roller brush 903 to rotate through the cleaning belt 904. The rotation of the roller brush 903, in conjunction with the cleaning nozzle 404, cleans the filter screen. The wastewater flows into the drain trough 602 through the lower inclined plate 203, and is then discharged through the drain pipe 601 for centralized treatment. After cleaning is completed, the cleaning motor 905 and the water pump stop. In the second purification chamber 5... As the cleaning mechanism at one end of chamber 03 enters the second purification chamber 503, the cleaning mechanism at one end of the first purification chamber 502 is gradually pulled out of the first purification chamber 502 with the movement of the lead screw 107. When the inclined plate 203 is pulled out, the front sealing plate 803 gradually descends as the inclined plate 203 gradually rises along the chamber slide groove 505, finally sealing the inlet of the cleaning component. At the same time, as the cleaning pipe 402 is gradually pulled out, the cleaning pipe 402 detaches from the cleaning fluid tank 401, and the tank sealing slider 406 returns to its original position through the sealing slider spring 407. Finally, the front sealing plate 405 of the cleaning pipe seals the inlet of the cleaning nozzle 404, and the inclined plate 203 also gradually slides upward along the slide rod 204 as it is pulled out.

[0060] As the lead screw 107 moves to the right towards the push plate 201, the push rod 303 rotatably connected to the lead screw 107 also moves synchronously. The movement of the push rod 303 drives the air vent sealing plate 302 to move, and the air vent sealing plate 302 gradually seals the first air intake pipe 507. At the same time, the second air outlet 304 gradually aligns with the second air intake pipe 508. The movement of the lead screw 107 drives the right push plate 201. When the right push plate 201 slides outward, it pulls the sliding partition 312 through the pull rod 310, opening the second air drying inlet 313, while simultaneously sealing the first air intake pipe 507. At the dry air inlet 311, because the opening of the air inlet 506 leading to the second purification chamber 503 is sealed, the oil fumes enter the first purification chamber 502 through the air inlet 506, and are then purified by the filter screen 308 inside the first purification chamber 502. After entering the first suction pipe 507, because the top of the first suction pipe 507 is sealed, the fumes enter the second purification chamber 503 through the first air supply pipe 306 installed on the first suction pipe 507, and are dried inside the filter screen 308 after it has been cleaned.
