[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A universal adaptable generator exhaust gas purification device includes a purification box 1, an air intake mechanism 5 on the left side of the purification box 1, a purification mechanism 6 inside the purification box 1, two purification mechanisms 6, an air intake fan 15 fixedly connected inside the purification box 1, and a sealing cover 4 on the left side of the purification box 1, the surface of the sealing cover 4 being in close contact with the inside of the purification box 1.

[0030] The air intake mechanism 5 includes a rotating rod 501, an air intake hood 502, two sliders 503 and two slide rails 504. The bottom of the rotating rod 501 is rotatably connected to the top of the air intake hood 502. The side of the slider 503 near the air intake hood 502 is fixedly connected to the air intake hood 502. The slider 503 is slidably connected inside the slide rail 504.

[0031] In this embodiment: the rotating rod 501 is threadedly connected to the inside of the connecting strip 9. Rotating the rotating rod 501 can drive the suction hood 502 to move up and down along the slide rail 504, adapting to generator exhaust ports of different heights. The suction hood 502 has a large opening, which can easily cover generator exhaust ports of different sizes. Its inner wall filter screen 7 intercepts large particulate impurities, and the elastic hose 8 ensures air passage continuity. The controller 12 is activated to generate negative pressure in the suction fan 15, which draws the generator exhaust gas into the purification box 1 through the elastic hose 8. The two sets of purification mechanisms 6 work in succession to purify the gas. The filter element 602 is made of composite material. The outer layer of glass fiber intercepts particulate matter, the middle layer of activated carbon adsorbs harmful gases, and the inner layer of metal fiber loads a catalyst to convert carbon monoxide. The cover 601 is connected to the connecting frame 16 and screws 18. Block 11 is fixed, and the bottom sealing ring 17 ensures the airtightness of the purification box 1. When replacing the filter element 602, remove the screw 18 to take off the cover 601, and pull the lever 603 to remove it. The protective cover 13 and protective net 14 on the right side of the purification box 1 protect the air intake fan 15. The bottom anti-slip strip 3 and the side handle 2 facilitate the fixing and transportation of the device. Pulling the sealing cover 4 can clean the dust blocked by the filter element 602 on the left side of the inner wall of the purification box 1. This solves the problem that the position of the air intake pipe is fixed in the existing patent, which is inconvenient to adjust according to the different heights of the exhaust pipes of different generators, resulting in low adaptability. In addition, an external connecting pipe is required to connect the air intake pipe and the generator exhaust pipe. When the size of the generator exhaust pipe opening is inconsistent with the air intake pipe opening, the connection is even more inconvenient.

[0032] Specifically, such as Figure 2 As shown, a connecting strip 9 is fixedly connected between the tops of the two slide rails 504, and the rotating rod 501 is threaded into the inside of the connecting strip 9.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, an elastic hose 8 is fixedly connected to the right side of the suction hood 502, and the right side of the elastic hose 8 is fixedly connected to the left side of the purification box 1. A filter screen 7 is fixedly connected to the inner wall of the suction hood 502.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, connecting rods 10 are fixedly connected to the top and bottom of the right side of the slide rail 504, and the right side of the connecting rods 10 is fixedly connected to the left side of the purification box 1.

[0035] In this embodiment: the rotating rod 501 is threaded into the inside of the connecting strip 9, so that it can move up and down when it rotates, which can easily drive the suction hood 502 to move up and down. The suction hood 502 is connected to the purification box 1 through the elastic hose 8, so that the suction hood 502 and the purification box 1 are connected when the suction hood 502 moves. The slide rail 504 is stably fixed to the left side of the purification box 1 through the connecting rod 10.

[0036] Specifically, such as Figure 4 As shown, the purification mechanism 6 includes a cover 601, a filter element 602, a pull rod 603, and a limiting frame 604. The limiting frame 604 is fixedly connected to the inner wall of the purification chamber 1. The filter element 602 is movably inserted into the inside of the limiting frame 604. The pull rod 603 is fixedly connected to the inside of the filter element 602. The bottom of the cover 601 contacts the top of the filter element 602, and the surface of the cover 601 is in movable contact with the inside of the purification chamber 1.

[0037] Specifically, such as Figure 5 As shown, the front and rear sides of the cover 601 are fixedly connected to the connecting bracket 16, and the front and rear sides of the purification box 1 are fixedly connected to the connecting block 11 that works with the connecting bracket 16. The top of the connecting bracket 16 is provided with a screw 18, and the bottom of the screw 18 passes through the connecting bracket 16 and is connected to the internal thread of the connecting block 11.

[0038] Specifically, such as Figure 5 As shown, a sealing ring 17 is fixedly connected to the bottom of the cover 601, and the bottom of the sealing ring 17 is in close contact with the top of the purification box 1.

[0039] In this embodiment: by controlling the operation of the suction fan 15 to generate negative pressure, the exhaust gas in the suction hood 502 is sucked into the purification box 1 through the elastic hose 8. The two sets of filter elements 602 installed in the purification box 1 take turns purifying the generator exhaust gas. After the generator exhaust gas undergoes multi-layer purification treatment, it can be discharged. By passing the screw 18 through the connecting bracket 16 and connecting it with the internal thread of the connecting block 11, the cover 601 can be easily connected to the purification box 1. The sealing ring 17 can seal the cover 601 and the purification box 1 to prevent the purification box 1 from leaking air.

[0040] Specifically, such as Figure 3As shown, a controller 12 is fixedly connected to the right side of the purification box 1, a protective cover 13 is provided on the right side of the air intake fan 15, a protective net 14 is fixedly connected inside the protective cover 13, anti-slip strips 3 are fixedly connected to the front and rear sides of the bottom of the purification box 1, and handles 2 are fixedly connected to the front and rear sides of the purification box 1.

[0041] In this embodiment: the air intake fan 15 can be easily controlled by operating the controller 12, the protective net 14 can protect the air intake fan 15, the anti-slip strip 3 can stably support the purification box 1 on a stable ground, and the purification box 1 can be easily moved by holding the handle 2.

[0042] Working principle: The rotating rod 501 is threaded into the connecting bar 9. When the rotating rod 501 is rotated, due to the threaded transmission principle, the intake hood 502, which is rotatably connected to its bottom, moves up and down along the slide rail 504. This allows the intake hood 502 to adapt to the exhaust ports of different generators at different heights. Because the intake hood 502 has a large opening, it can be easily moved into the interior of the generator exhaust port displacement intake hood 502, exhibiting high adaptability. The filter screen 7 on the inner wall of the intake hood 502 can initially intercept large particulate impurities in the generator exhaust gas, preventing them from clogging subsequent pipelines. At the same time, the flexible hose fixedly connected to the right side of the intake hood 502... 8. Ensure that the suction hood 502 remains stably connected to the purification box 1 while moving. Start the controller 12 to turn on the suction fan 15. The suction fan 15 generates negative pressure, drawing the exhaust gas from the suction hood 502 into the purification box 1 through the flexible hose 8. The two sets of purification mechanisms 6 inside the purification box 1 work together to purify the exhaust gas. The filter element 602 is made of composite material. The outer layer is made of woven glass fiber, which can efficiently intercept particulate matter and soot in the exhaust gas. The middle layer is activated carbon impregnated with active components, which can adsorb harmful gases such as nitrogen oxides and hydrocarbons. The inner layer is made of metal fiber substrate and loaded with a catalyst coating, which can catalyze the conversion of gases such as carbon monoxide into harmless substances. The generator exhaust gas passes through two sets of filter elements 602 sequentially under the action of the intake fan 15. After multi-layer purification treatment, it can be easily discharged. The cover 601 is fixed to the connecting block 11 by the connecting bracket 16, screws 18, and the bottom sealing ring 17 ensures the airtightness of the purification box 1 to prevent leakage of unpurified exhaust gas. The filter element 602 is movably inserted into the limiting frame 604. By removing the screws 18, the cover 601 can be removed, and then the filter element 602 can be easily removed and replaced by pulling the lever 603. The protective cover 13 and protective net 14 on the right side of the purification box 1 protect the intake fan 15. The bottom anti-slip strip 3 and the side handle 2 facilitate the fixing and transportation of the device. By pulling the sealing cover 4 to detach it from the purification box 1, the dust blocked by the left filter element 602 in the space on the left side of the inner wall of the purification box 1 can be easily cleaned. Since the purification box 1 is under negative pressure when the exhaust fan 15 is working, the sealing cover 4 will not fall off. This solves the problem in the existing patent that the position of the air inlet pipe is fixed, which is inconvenient to adjust according to the different heights of the exhaust pipes of different generators, resulting in low adaptability. In addition, an external connecting pipe is required to connect the air inlet pipe and the generator exhaust pipe. When the size of the generator exhaust pipe opening is different from that of the air inlet pipe opening, the connection is even more inconvenient.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
