Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, specifically to a laser cutting machine with dust removal function. Background Technology

[0002] Laser cutting machines, with their high precision and high efficiency, have been widely used in the processing of various materials such as metal materials (e.g., H-beams, ordinary steel) and lithium battery electrodes. They occupy an important position in the processing needs of everything from general manufacturing to special industries. However, laser cutting relies on a high power density beam to melt or vaporize materials, which inevitably generates a large amount of debris and dust. In some cases, the cutting of materials may also be accompanied by toxic and harmful gases.

[0003] A laser cutting machine with dust removal function, patent publication number CN222536602U, includes a frame, a top plate fixedly connected to the top of the frame, a laser cutting machine mounted at the bottom of the top plate, and a housing fixedly connected to the top of the top plate. A gas collection hood is slidably connected to the inner side of the frame, and a fan is bolted to one side of the outer wall of the frame. The air inlet of the fan is connected to the top of the gas collection hood. The method proposed in this document collects surrounding dust through the gas collection hood and housing, thereby achieving rapid and timely dust collection and preventing dust from affecting the cutting effect.

[0004] However, in the aforementioned laser cutting machine with dust removal function, the air collection hood cannot fully cover the inside of the frame. When the fan draws air from the inside of the frame, since both sides of the frame are connected to the outside, the dust will be carried by the airflow to the outside of the frame and float in the air, causing environmental pollution and thus harming the health of workers. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a laser cutting machine with dust removal function, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting machine with dust removal function, comprising a housing, a fan fixed to the side wall of the housing, an air suction pipe provided on the upper surface of the fan, the fan communicating with the air suction pipe, the air suction pipe penetrating the side wall of the housing and being fixedly connected at the penetration point, a vacuum cleaner fixed to the end of the air suction pipe away from the fan, the air suction pipe communicating with the vacuum cleaner, a connecting pipe fixed to the upper surface of the fan, the connecting pipe communicating with the fan, a filter box fixed to the upper surface of the housing, the connecting pipe communicating with the filter box, a filter plate fixed to the inner wall of the filter box, the filter box containing clean water, an exhaust pipe fixed to the end of the filter box away from the connecting pipe, a laser cutting machine body fixed to the upper surface of the inner wall of the housing, a push-pull device for sealing the housing provided inside the housing, and a limiting device for positioning auxiliary materials provided inside the housing; The push-pull device includes a vertical plate, a placement plate, a positioning strip, a clamping spring, a clamping plate, a push plate, a heat-conducting block, and a baffle.

[0009] According to the above technical solution, the limiting device includes a reset spring, a sliding plate, a limiting spring, a limiting plate, a push rod, a sliding block, a striking rod, a connecting rod, and a spoiler. The reset spring is fixedly connected to the side wall of the inner wall of the outer shell, and the sliding plate is slidably connected to the bottom surface of the inner wall of the outer shell. When the plate slides, it pushes the sliding plate to slide.

[0010] According to the above technical solution, the side wall of the sliding plate is fixedly connected to the end of the reset spring away from the side wall of the outer shell, the limiting spring is fixedly connected to the end of the sliding plate away from the reset spring, the limiting plate is fixedly connected to the end of the limiting spring away from the sliding plate, the bottom surface of the limiting plate is in contact with the upper surface of the placement plate, and the sliding plate moves the limiting plate when it slides.

[0011] According to the above technical solution, the push rod is hinged to the upper surface of the left sliding plate, the sliding block is slidably connected to the left side wall of the inner wall of the outer shell, the end of the push rod away from the sliding plate is hinged to the end of the sliding block away from the side wall of the outer shell, and the striking rod is fixedly connected to the upper surface of the sliding block. When the sliding block slides, the outer shell is struck by the striking rod.

[0012] According to the above technical solution, the connecting rod is hinged to the bottom end of the sliding block sidewall, and the spoiler is hinged to the left sidewall of the inner wall of the outer shell. The bottom end of the spoiler sidewall is hinged to the end of the connecting rod away from the sliding block. There are two sets of connecting rods and spoilers, which are respectively set on the left and right sides of the sliding block. The spoiler turbulents the interior of the outer shell.

[0013] According to the above technical solution, the interior of the outer shell is provided with an auxiliary device for cleaning the dead corners of the vacuum cleaner. The auxiliary device includes a hinge rod, a dust collection plate, a return spring, a scraper and a squeezing block. The hinge rod is hinged to the side wall of the right sliding plate, and the dust collection plate is slidably connected to the bottom surface of the inner wall of the outer shell.

The scraper pushes the dust to the front of the vacuum cleaner.

[0015] This invention provides a laser cutting machine with a dust removal function. It has the following beneficial effects: 1. This invention is equipped with a push-pull device. When cutting the material, the upright plate and placement plate completely seal the outer shell, preventing dust from flying into the air and polluting the environment during cutting. Simultaneously, positioning strips, clamping springs, and clamping plates clamp the material, preventing it from shifting as it is drawn into the outer shell with the upright plate and placement plate. This solves the problems of material displacement during cutting and the difficulty in quickly drawing in dust, which then pollutes the environment. During sealing, a push plate, heat-conducting block, and baffle plate work together to insert the heat-conducting block into clean water. The water in the filter box cools the heat-conducting block, increasing the speed of heat dissipation from the air inside the shell. This prevents excessive heat inside the shell after sealing, which could cause the material to expand and cause cutting errors. This solves the problem of excessive temperature in the sealed environment leading to material deformation and cutting errors.

[0016] 2. This invention incorporates a limiting device. After the upright plate and placement plate are inserted into the outer casing, the material is aligned and positioned using a return spring, sliding plate, limiting spring, and limiting plate. This prevents the material from shifting its angle due to vibration when the upright plate and placement plate are fixed, solving the problem of difficulty in manually adjusting the material's position after it is retracted into the outer casing. During material positioning, the outer casing is struck using a push rod, sliding block, striking rod, connecting rod, and spoiler, causing it to vibrate and detach dust adhering to the inner wall of the casing. The spoiler further increases the distance the dust travels after detaching from the casing, making it easier for the vacuum cleaner to suck it in. This prevents dust from adhering to the inner wall of the casing and being difficult to suck in, solving the problem of vacuum cleaners struggling to remove dust adhering to the inner wall of the casing during vacuuming.

[0017] 3. This invention includes an auxiliary device that, when positioning materials, works with the hinge rod and dust collection plate to gather dust in the dead corners of the vacuum cleaner. This prevents dust from flying into the dead corners of the vacuum cleaner when it is inside the casing, and from flying out of the casing when the upright plate and placement plate are pulled out, thus avoiding environmental pollution. This solves the problem of dust being blocked by the upright plate and placement plate in the dead corners of the vacuum cleaner and flying into the environment when the upright plate and placement plate are pulled out. When gathering dust in the dead corners, a return spring, scraper, and squeezing block work together to push the gathered dust to the front of the vacuum cleaner. The baffle in the limiting device makes the dust fly up, allowing the vacuum cleaner to suck up the dust more completely, thus solving the problem that dust in the dead corners is difficult to be completely sucked up by the vacuum cleaner.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 One embodiment of the present invention is as follows: A laser cutting machine with dust removal function includes a housing 1, a fan 2 fixed to the side wall of the housing 1, an air suction pipe provided on the upper surface of the fan 2, the fan 2 communicating with the air suction pipe, the air suction pipe penetrating through the side wall of the housing 1 and fixedly connected at the penetration point, a vacuum cleaner 3 fixed to the end of the air suction pipe away from the fan 2, the air suction pipe communicating with the vacuum cleaner 3, before and after cutting the material, the fan 2 is activated, the fan 2 sucks dust from the inside of the housing 1 through the vacuum cleaner 3, a connecting pipe is fixed to the upper surface of the fan 2, the connecting pipe communicating with the fan 2, and a connecting pipe is fixed to the upper surface of the housing 1. The filter box 4 is connected to the connecting pipe. The dust and air sucked in by the fan 2 from the vacuum cleaner 3 are discharged into the filter box 4 through the connecting pipe. The filter box 4 is fixed with a filter plate on the inner wall. The filter box 4 is filled with clean water. The end of the filter box 4 away from the connecting pipe is fixed with an exhaust pipe. After the dust and air are discharged into the filter box 4, the clean water in the filter box 4 will reduce the dust in the air. Then the filter plate will filter the air and discharge it from the exhaust pipe. The upper surface of the inner wall of the outer shell 1 is fixed with the laser cutting machine body 5. The inside of the outer shell 1 is equipped with a push-pull device to seal the outer shell 1.

[0022] The push-pull device includes a vertical plate 61, a placement plate 62, a positioning strip 63, a clamping spring 64, a clamping plate 65, a push plate 66, a heat-conducting block 67, and a baffle 68. The vertical plate 61 is slidably connected to the side wall of the inner wall of the outer shell 1, and the placement plate 62 is fixedly connected to the side wall of the vertical plate 61 and slidably connected to the bottom surface of the inner wall of the outer shell 1. When material needs to be cut, the vertical plate 61 is pulled to remove the vertical plate 61 and the placement plate 62 from the inside of the outer shell 1. The positioning strip 63 is fixedly connected to the upper surface of the placement plate 62, the clamping spring 64 is fixedly connected to the side wall of the vertical plate 61, and the clamping plate 65 is fixedly connected to the end of the clamping spring 64 away from the vertical plate 61. When the clamping plate 65 is pushed towards the vertical plate 61, it slides towards the vertical plate 61, thus clamping the clamping spring. Compression is applied to the material to be cut, which is then placed on the placement plate 62. The clamping plate 65 is released, and it slides towards the material under the restoring force of the clamping spring 64. The clamping plate 65 pushes the material to be cut to move. When the clamping plate 65 moves the material to be cut to the positioning strip 63, the positioning strip 63 blocks the material, stopping it. The clamping plate 65, under the elastic force of the clamping spring 64 and in cooperation with the positioning strip 63, clamps the material. The clamping plate 65 is slidably connected to the upper surface of the placement plate 62. The push plate 66 is fixedly connected to the side wall of the upright plate 61 and slidably connected to the upper surface of the inner wall of the outer shell 1. The heat-conducting block 67 penetrates the upper surface of the outer shell 1 and is slidably connected at the penetration point. After the material is placed, the upright plate 61 is pushed to move the upright plate 62. 1. The upright plate 61 and the placement plate 62 are inserted into the outer casing 1. The upright plate 61, the placement plate 62, and the push plate 66 seal the side of the outer casing 1. After the push plate 66 is inserted into the outer casing 1 along with the upright plate 61, it pushes the heat-conducting block 67 to slide upward. When the heat-conducting block 67 slides upward, it also drives the baffle 68 to move upward. The heat-conducting block 67 and the baffle 68 are made of heat-conducting material and absorb heat from the inside of the outer casing 1. When the heat-conducting block 67 slides upward, the contact area between the outer wall of the heat-conducting block 67 and the clean water in the filter box 4 increases. The heat-conducting block 67 dissipates the absorbed heat to the clean water. The heat-conducting block 67 penetrates the bottom surface of the filter box 4 and is slidably connected at the penetration point. The baffle 68 is fixedly connected to the upper surface of the heat-conducting block 67. When the push plate 66 is pulled out along with the upright plate 61, the heat-conducting block 67 is no longer subjected to heat. The push-pull device, supported by the push plate 66 and simultaneously subjected to the gravity of itself and the water above it, slides downwards, causing the baffle 68 to move downwards as well. When the baffle 68 reaches the bottom of the filter box 4, it stops, limiting the heat-conducting block 67. When cutting the material, the push-pull device completely seals the outer shell 1 through the upright plate 61 and the placement plate 62, thereby preventing dust from flying into the air and polluting the environment during material cutting. At the same time, the positioning strip 63, clamping spring 64, and clamping plate 65 clamp the material, preventing the material from shifting when it is drawn into the outer shell 1 along with the upright plate 61 and the placement plate 62. This solves the problems of material displacement during cutting and the difficulty in quickly drawing in dust, which then flies into the air and pollutes the environment. When sealing the outer shell 1, the heat-conducting block 67 is inserted into clean water in conjunction with the push plate 66, the heat-conducting block 67 and the baffle 68. The clean water in the filter box 4 cools down the heat-conducting block 67, increases the heat dissipation speed of the air inside the outer shell 1, and avoids the excessive heat inside the outer shell 1 after sealing, which would cause the material to expand due to heat and cause cutting errors. This solves the problem of excessive temperature in the sealed environment causing material deformation and cutting errors.

[0023] In this embodiment, before and after cutting the material, the fan 2 is started. The fan 2 uses the vacuum cleaner 3 to vacuum the inside of the outer casing 1. The dust sucked in by the fan 2 from the vacuum cleaner 3 along with the air is discharged into the filter box 4 through the connecting pipe. After the dust and air are discharged into the filter box 4, the air is dusted by the clean water in the filter box 4, and then the air is filtered by the filter plate and discharged from the exhaust pipe.

[0024] When material needs to be cut, pull the upright plate 61 to remove it and the placement plate 62 from the inside of the outer shell 1. Move the clamping plate 65 towards the upright plate 61. As the clamping plate 65 slides towards the upright plate 61, it compresses the clamping spring 64. Place the material to be cut onto the placement plate 62. Release the clamping plate 65. The clamping plate 65 slides towards the material to be cut under the restoring force of the clamping spring 64. The clamping plate 65 pushes the material to be cut to move. When the clamping plate 65 moves the material to be cut to the positioning strip 63, the positioning strip 63 blocks the material to be cut, stopping it. The clamping plate 65, under the elastic force of the clamping spring 64 and in cooperation with the positioning strip 63, clamps the material. After the material is placed, push the upright plate 61 to insert the upright plate 61 and the placement plate 62 into the outer shell 1. The upright plate 61, the placement plate 62, and the push plate 66 seal the side of the outer shell 1. The push plate 66 moves with the upright plate 61. After plate 61 is inserted into outer shell 1, push plate 66 slides on the upper surface of inner wall of outer shell 1. When push plate 66 slides to heat-conducting block 67, the side of push plate 66 slides against the inclined surface of heat-conducting block 67. Push plate 66 pushes heat-conducting block 67 upward. When heat-conducting block 67 slides upward, it drives baffle 68 to move upward as well. Heat-conducting block 67 and baffle 68 are made of heat-conducting material and absorb heat from inside outer shell 1. When heat-conducting block 67 slides upward, the contact area between the outer wall of heat-conducting block 67 and the clean water in filter box 4 increases. Heat-conducting block 67 dissipates the absorbed heat to the clean water. When push plate 66 is pulled out along with upright plate 61, heat-conducting block 67 is no longer supported by push plate 66 and slides downward by its own weight and the weight of the clean water above it, driving baffle 68 to move downward as well. When baffle 68 moves to the bottom surface of filter box 4, it stops and limits heat-conducting block 67.

[0025] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, a limiting device for positioning auxiliary materials is provided inside the outer shell 1. The limiting device includes a return spring 71, a sliding plate 72, a limiting spring 73, a limiting plate 74, a push rod 75, a sliding block 76, a striking rod 77, a connecting rod 78, and a spoiler 79. The return spring 71 is fixedly connected to the side wall of the inner wall of the outer shell 1, and the sliding plate 72 is slidably connected to the bottom surface of the inner wall of the outer shell 1. The side wall of the sliding plate 72 is fixedly connected to the end of the return spring 71 away from the side wall of the outer shell 1. When the placement plate 62 slides to the sliding plate 72 on the inner wall of the outer shell 1, the placement plate 62 pushes the sliding plate 72 to slide away from the placement plate 62. The return spring 71 is compressed, the limiting spring 73 is fixedly connected to the end of the sliding plate 72 away from the return spring 71, and the limiting plate 74 is fixedly connected to the end of the limiting spring 73 away from the sliding plate 72. The bottom surface of the limiting plate 74 is in contact with the upper surface of the placement plate 62. The sliding plate 72 drives the limiting spring 73 and the limiting plate 74 to move away from the placement plate 62. When the upright plate 61 and the placement plate 62 have fully inserted the material to be cut into the outer shell 1, due to the special shape of the placement plate 62, the sliding plate 72 is no longer pushed by the placement plate 62, but is reset by the restoring push of the return spring 71. When the sliding plate 72 resets, it drives the limiting spring 73 and the limiting plate 74 to reset as well. When the limiting plate 74 moves to the material to be cut, it pushes... The material to be cut is aligned, and limit springs 73 and limit plates 74 are provided on both sides of the placement plate 62. After the material is aligned, the limit springs 73 are compressed by the limit plates 74. The restoring force of the limit springs 73 pushes the limit plates 74 to position the material. The push rod 75 is hinged to the upper surface of the left sliding plate 72. When the sliding plate 72 slides away from the placement plate 62, it also drives the push rod 75 to rotate. The sliding block 76 is slidably connected to the left side wall of the inner wall of the outer shell 1. The end of the push rod 75 away from the sliding plate 72 is hinged to the end of the sliding block 76 away from the side wall of the outer shell 1. The rotation of the push rod 75 pushes the sliding block 76 to slide upward. The striking rod 77 is fixedly connected to the upper surface of the sliding block 76. When the sliding block 76 slides upward, it drives the striking rod 77 to rotate. The striking rod 77 also moves upward, striking the outer casing 1. The connecting rod 78 is hinged to the bottom end of the side wall of the sliding block 76. When the sliding block 76 slides upward, it also drives the connecting rod 78 to rotate. The spoiler 79 is hinged to the left side wall of the inner wall of the outer casing 1. The bottom end of the side wall of the spoiler 79 is hinged to the end of the connecting rod 78 away from the sliding block 76. There are two sets of connecting rods 78 and spoilers 79, respectively set on the left and right sides of the sliding block 76. The connecting rod 78 drives the spoiler 79 to rotate, and the spoiler 79 fans the dust to fly inside the outer casing 1. After the upright plate 61 and the placement plate 62 are inserted into the outer casing 1, the limiting device, together with the return spring 71, the sliding plate 72, the limiting spring 73 and the limiting plate 74, aligns and positions the material.This avoids the material's angle shifting due to its own vibration when fixed on the upright plate 61 and the placement plate 62, and solves the problem of difficulty in manually adjusting the material's position after it is retracted into the outer casing 1; When positioning the material, the push rod 75, sliding block 76, striking rod 77, connecting rod 78 and baffle 79 are used to strike the outer shell 1, causing the outer shell 1 to vibrate. This causes the dust adhering to the inner wall of the outer shell 1 to detach from the inner wall of the outer shell 1. The baffle 79 then increases the distance the dust travels after detaching from the outer shell 1, making it easier for the dust to be sucked up by the vacuum cleaner 3. This avoids the problem of dust adhering to the inner wall of the outer shell 1 and being difficult to suck up, thus solving the problem that the vacuum cleaner 3 has difficulty sucking up the dust adhering to the inner wall of the outer shell 1 when vacuuming.

[0026] The interior of the outer casing 1 is equipped with an auxiliary device for cleaning dust from the hard-to-reach areas of the vacuum cleaner 3. This auxiliary device includes a hinge rod 81, a dust collection plate 82, a return spring 83, a scraper 84, and a pressing block 85. The hinge rod 81 is hinged to the side wall of the right-side sliding plate 72. When the sliding plate 72 slides away from the placement plate 62, it also drives the hinge rod 81 to rotate. The dust collection plate 82 is slidably connected to the bottom surface of the inner wall of the outer casing 1. The side wall of the dust collection plate 82 is hinged to the end of the hinge rod 81 away from the sliding plate 72. The rotation of the hinge rod 81 pushes the dust collection plate 82 to slide away from the sliding plate 72, causing the dust adhering to the inner wall of the outer casing 1 to gather together. The return spring 83 is fixedly connected to a protrusion on the side wall of the dust collection plate 82. The scraper 84 is fixedly connected to the end of the return spring 83 away from the protrusion on the dust collection plate 82. The scraper 84 is slidably connected to the side wall of the dust collection plate 82, and the sliding of the dust collection plate 82 causes it to return to its original position. Spring 83 and scraper 84 also slide. Extrusion block 85 is fixedly connected to the right side wall of the inner wall of housing 1. When scraper 84 slides to extrusion block 85, the side of scraper 84 slides against the inclined surface of extrusion block 85. Extrusion block 85 pushes scraper 84 to slide away from the side wall of housing 1. When scraper 84 slides, it compresses return spring 83. Sliding scraper 84 pushes the dust that has gathered together to the front of vacuum cleaner 3. When positioning materials, this auxiliary device, together with hinge rod 81 and dust collection plate 82, gathers dust in the dead corner of vacuum cleaner 3, thereby preventing dust from flying into the dead corner of vacuum cleaner 3 when it flies inside housing 1 and flies out from inside housing 1 when the upright plate 61 and placement plate 62 are pulled out, causing environmental pollution. This solves the problem that dust is blocked by upright plate 61 and placement plate 62 in the dead corner of vacuum cleaner 3 and flies into the environment when the upright plate 61 and placement plate 62 are pulled out. When dust accumulates in corners, the return spring 83, scraper 84 and squeezing block 85 push the accumulated dust to the front of the vacuum cleaner 3. The baffle 79 in the limiting device makes the dust fly up, so that the vacuum cleaner 3 can suck up the dust more completely, solving the problem that dust is difficult to be completely sucked up by the vacuum cleaner 3 in corners.

[0027] In this embodiment, during operation: when the placement plate 62 slides along the inner wall of the outer casing 1 to the sliding plate 72, the side of the sliding plate 72 slides against the inclined surface of the placement plate 62. The placement plate 62 pushes the sliding plate 72 to slide away from the placement plate 62. When the sliding plate 72 slides away from the placement plate 62, it compresses the return spring 71. The sliding plate 72 also drives the limiting spring 73 and the limiting plate 74 to move away from the placement plate 62. After the upright plate 61 and the placement plate 62 have fully inserted the material to be cut into the outer casing 1, the material is then... Due to the special shape of the placement plate 62, the sliding plate 72 is no longer pushed by the placement plate 62, but is reset by the restoring force of the return spring 71. When the sliding plate 72 resets, it also drives the limit spring 73 and the limit plate 74 to reset. When the limit plate 74 moves to the material to be cut, it pushes the material to be cut to be aligned. Since limit springs 73 and limit plates 74 are provided on both sides of the placement plate 62, after the material is aligned, the limit plate 74 compresses the limit spring 73. The restoring force of the limit spring 73 pushes the limit plate 74 to cut the material. In the positioning process, when the sliding plate 72 slides away from the placement plate 62, it also causes the hinge point between the sliding plate 72 and the push rod 75 to move. The end of the push rod 75 away from the sliding plate 72 is hinged to the sliding block 76, and the sliding block 76 can only slide vertically. Therefore, the hinge point between the push rod 75 and the sliding block 76 can only move vertically. When the sliding plate 72 slides away from the placement plate 62, it causes the push rod 75 to rotate. The rotation of the push rod 75 pushes the sliding block 76 upwards. When sliding, the striking rod 77 moves upward, impacting the outer casing 1. When the sliding block 76 slides upward, it also moves the hinge point between the connecting rod 78 and the sliding block 76 upward. The end of the connecting rod 78 away from the sliding block 76 is hinged to the spoiler 79, and the spoiler 79 can only rotate around the hinge point between the spoiler 79 and the outer casing 1. Therefore, when the sliding block 76 slides upward, it drives the connecting rod 78 to rotate, and the connecting rod 78 drives the spoiler 79 to rotate. The spoiler 79 fans dust into the interior of the outer casing 1.

[0028] When the sliding plate 72 slides away from the placement plate 62, it also causes the hinge point between the sliding plate 72 and the hinge rod 81 to move. The end of the hinge rod 81 away from the sliding plate 72 is hinged to the dust collection plate 82, and the dust collection plate 82 can only slide against the inner wall of the outer casing 1. Therefore, when the sliding plate 72 slides, it causes the hinge rod 81 to rotate. The rotation of the hinge rod 81 pushes the dust collection plate 82 to slide away from the sliding plate 72. The dust collection plate 82 pushes the dust against the inner wall of the outer casing 1 to gather together. The sliding of the dust collection plate 82 also causes the return spring 83 and the scraper 84 to move. When the scraper 84 slides to the squeezing block 85, the side of the scraper 84 slides against the inclined surface of the squeezing block 85. The squeezing block 85 pushes the scraper 84 to slide away from the side wall of the outer casing 1. When the scraper 84 slides, it compresses the return spring 83. The sliding of the scraper 84 pushes the dust that has gathered together to the front of the vacuum cleaner 3. When the sliding plate 72 is reset, the sliding plate 72 drives the hinge rod 81 to rotate and reset. The rotation of the hinge rod 81 drives the dust collection plate 82 to reset as well. After the dust collection plate 82 is reset, the scraper 84 is also reset by the restoring force of the return spring 83.
