The anti-accidental touch components include a fixed cylinder, the bottom of the fixed cylinder is fixedly connected to the top of the base, a notch is provided on the inner wall of the fixed cylinder, a spring bead is contacted on the inner wall of the notch, a moving column 1 is contacted on the inner wall of the fixed cylinder, and a limiting groove is provided on the outer surface of the moving column 1; The cleaning assembly includes two cleaning assemblies, and the two cleaning assemblies include the same parts. The cleaning assembly includes a second moving column, a spring column is fixedly connected to the top of the second moving column, a second fixed plate is contacted to the bottom of the spring column, and a first brush plate is fixedly connected to the left side of the spring column. When the staff lifts the device as a whole, due to the effect of the anti-mistouch assembly, the rise of the box body will not drive the second moving column to move synchronously, but the second fixed plate will move synchronously when the box body is raised. Since the second fixed plate is arranged in a stepped shape, the spring column can be in contact with it and shake left and right when the second fixed plate moves. The left and right shaking spring column will drive the first brush plate to sweep away the impurities and dust accumulated on the inner wall of the box, so that the impurities and dust fall to the bottom of the inner wall of the box, so that the device can easily and quickly clean the inner wall, avoiding the problem of excessive dust accumulation inside and affecting the filtering effect. At the same time, the staff can clean the inner wall of the device without manual operation when disassembling the device as a whole, reducing the workload of the staff.

[0005] Preferably, the inner wall of the protective shell is in contact with the outer surface of the second pressing block, a fixed column 1 is fixedly connected to the bottom of the second pressing block, a sliding column is fixedly connected to the bottom of the fixed column 1, a sliding rail is fixedly connected to the bottom of the inner wall of the protective shell, a sliding block is slidably connected to the inner wall of the sliding rail, an inclined groove is provided on the front of the sliding block, the inner wall of the inclined groove is in contact with the outer surface of the sliding column, a spring 1 is fixedly connected to the right side of the sliding block, and the right side of the spring 1 is fixedly connected to the left side of the inner wall of the protective shell. The staff of the present invention presses the pressing block 1 to move the outer shell downward, and the downward movement of the outer shell will simultaneously drive the two pressing blocks 2 to move synchronously. The movement of the two pressing blocks will press the fixed column 1 inside the protective shell downward. Since an inclined groove is provided on the front side of the sliding block, the fixed column 1 will drive the sliding column to press downward to move the sliding block in the opposite direction of the box body, so that the sliding block is pulled out of the fixing hole provided in the box body, and the device is freed from the restriction. At this time, the staff can lift the outer shell and lift it out of the base, which is convenient for the staff to quickly disassemble the device. Compared with the previous cumbersome disassembly method, this method can make it more convenient and quick for the staff to disassemble the device, and can save a lot of time.

[0006] Preferably, a telescopic column is fixedly connected to the bottom of the second movable column, a hook is rotatably connected to the outer surface of the telescopic column through a pin shaft, a sliding ring is slidably connected to the side of the outer surface of the telescopic column close to the first movable column, and a fixed plate is fixedly connected to the side of the outer surface of the telescopic column away from the sliding ring.

[0007] Preferably, the inner wall of the fixed plate 1 is rotatably connected to a rotating rod, the number of the fixed plates 1 is several, and the several fixed plates 1 are arranged in a circular array. The top of the rotating rod is rotatably connected to a rope 1, and the top of the rope 1 is rotatably connected to the outer surface of the telescopic column. When the lifting device is lifted, the telescopic column drives the rope 1 to be pulled, and the pulling of the rope 1 causes the rotating rod to rotate under the restriction of the fixed plate 1. Since the lower part of the rotating rod is bent, when the rope 1 is pulled, the bent side of the rotating rod will continue to approach the inner wall of the moving column 1 until the plurality of rotating rods play the effect of internal support for the inner wall of the moving column 1. At this time, continuing to lift the device upward will drive the moving column 1 to be lifted upward. When the limiting groove provided in the moving column 1 is lifted to the position of the spring bead, the spring bead will bounce into the limiting groove to restrict it, so that the moving column 1 is fixed. At this time, the device is moved downward. Since the fixed plate 1 is larger than the diameter of the moving column 1, the continuously descending telescopic column will drive the hook to continue to move downward until it is hung on the bottom of the telescopic column. The contraction of the telescopic column will reset the rotating rod, cancel the restriction on the moving column 1, and the device can be taken out as a whole. The device can avoid the problem that the connection between the device and the ventilation duct is damaged due to the staff forgetting to completely disassemble or improperly operating when the device and the ventilation duct are not completely disassembled, and the device can also be operated subsequently.

[0008] Preferably, the two cleaning components are symmetrically arranged with fixed plate 2 as the center, fixed plate 2 is fixedly connected to the bottom of the inner wall of the box, and the back of fixed plate 2 is rotatably connected with a spring rotating plate. There are several spring rotating plates, and the several spring rotating plates are arranged in a vertical array.

[0009] Preferably, a collecting assembly is provided inside the box body, and there are two collecting assemblies. The two collecting assemblies are symmetrically arranged with the spring rotating plate as the center. The parts contained in the two collecting assemblies are the same. The collecting assembly includes a lower pressure plate, and the front side of the lower pressure plate is fixedly connected to the back side of the second moving column. There are two moving columns, and the right side of the second moving column located on the right side is rotatably connected with rope two.

[0010] Preferably, the bottom of rope 2 contacts with fixed column 2, the right side of fixed column 2 is fixedly connected to the right side of the inner wall of the box, the bottom of the inner wall of the box contacts with a scraper, the top of the scraper is fixedly connected to a connecting plate, the front of the scraper is fixedly connected to brush plate 2, the back of the scraper is fixedly connected to spring 2, a limiting groove is opened on the right side of the scraper, the inner wall of the limiting groove is slidably connected to the right side of the inner wall of the box, an assembly groove is opened at the bottom of the inner wall of the box, a spring pressing block is slidably connected to the inner wall of the assembly groove, and a stopper is fixedly connected to the top of the spring pressing block. The present invention continuously lifts the box body to make the lower pressure plate contact with the spring pressing block and press it downward. The spring pressing block will drive the stopper to move synchronously while pressing downward. The movement of the stopper will release the restriction of the scraper. The scraper after the restriction is released will be ejected under the action of spring 2. The ejected scraper will drive the brush plate 2 to move synchronously when it moves to the front end position of the brush plate 2, so as to push the dust and residue remaining at the bottom of the inner wall of the box body and the dust scraped by the brush plate 1, and all the dust will be scraped into the dust box. The staff can directly remove the dust box without manually collecting the dust, so that the device can collect dust after the internal cleaning is completed, which is convenient for thorough cleaning of the inside of the device.

[0011] A method for using a quickly detachable human anti-poison filter device, comprising the following steps: S1: dismantle the entire device; S2: lift and lower the device to clean the inside; S3: Disassemble the device and remove the dust box.

[0012] The present invention has the following beneficial effects: (1) When the staff of the present invention lifts the device as a whole, due to the effect of the anti-mistouch component, the lifting of the box body will not drive the movable column 2 to move synchronously. However, the fixed plate 2 will move synchronously when the box body is lifted. Since the fixed plate 2 is arranged in a stepped shape, the spring column can be in contact with it and swing left and right when the fixed plate 2 moves. The swinging spring column will drive the brush plate 1 to sweep away the impurities and dust accumulated on the inner wall of the box body and make them fall to the bottom of the inner wall of the box body, so that the device can clean the inner wall easily and quickly, avoiding the problem of excessive dust accumulation inside and affecting the filtering effect. At the same time, the staff can clean the inner wall of the device without manual operation when disassembling the device as a whole, thereby reducing the workload of the staff.

[0013] (2) The staff of the present invention presses the pressing block 1 to move the outer shell downward. The downward movement of the outer shell will simultaneously drive the two pressing blocks 2 to move synchronously. The movement of the two pressing blocks will press the fixed column 1 inside the protective shell downward. Since the front of the sliding block is provided with an inclined groove, the fixed column 1 will drive the sliding column to move in the opposite direction of the box body while pressing it downward, so that the sliding block is pulled out of the fixing hole provided in the box body, so that the device is freed from the restriction. At this time, the staff can lift the outer shell and lift it out of the base, which is convenient for the staff to quickly disassemble the device. Compared with the previous complicated disassembly method, this method can make it more convenient and quick for the staff to disassemble the device, which can save a lot of time.

[0014] (3) The present invention continuously lifts the box body so that the telescopic column drives the rope 1 to be pulled. The pulling of the rope 1 causes the rotating rod to rotate under the restriction of the fixed plate 1. Since the lower part of the rotating rod is bent, when the rope 1 is pulled, the bent side of the rotating rod will continue to approach the inner wall of the moving column 1 until a plurality of rotating rods play an internal support effect on the inner wall of the moving column 1. At this time, continuing to lift the device upward will drive the moving column 1 to be lifted upward. When the limit groove provided in the moving column 1 is lifted to the position of the spring bead, the spring bead will bounce into the limit groove to restrict it, so that the moving column 1 is fixed. At this time, the device is moved downward. Since the fixed plate 1 is larger than the diameter of the moving column 1, the continuously descending telescopic column will drive the hook to continue to move downward until it is hung on the bottom of the telescopic column. The contraction of the telescopic column will reset the rotating rod, cancel the restriction on the moving column 1, and allow the device to be taken out as a whole. The device can avoid the problem that the worker forgets to completely disassemble the device or improperly lifts the device when the device and the ventilation duct are not completely disassembled, causing damage to the connection between the device and the ventilation duct. At the same time, the device can also be operated subsequently.

[0015] (4) The present invention continuously lifts the box body so that the lower pressure plate contacts the spring pressing block and presses it downward. The spring pressing block drives the block to move synchronously while pressing downward. The movement of the block releases the restriction of the scraper. The scraper after the restriction is released will be ejected under the action of spring 2. The ejected scraper will drive brush plate 2 to move synchronously when it moves to the front end of brush plate 2, thereby pushing the dust and residue remaining at the bottom of the inner wall of the box body and the dust scraped by brush plate 1, and scraping all the dust into the dust box. The staff can directly remove the dust box without manually collecting the dust, so that the device can collect dust after the internal cleaning is completed, which is convenient for thorough cleaning of the inside of the device.

The cleaning assembly 4 includes a movable column 2 41, a spring column 411 is fixedly connected to the top of the movable column 2 41, the bottom of the spring column 411 contacts with a fixed plate 2 42, and a brush plate 1 412 is fixedly connected to the left side of the spring column 411. When the staff of the present invention lifts the device as a whole, due to the action of the anti-mistouch component 3, the raising of the box body 1 will not drive the movable column 2 41 to move synchronously. However, the fixed plate 2 42 will move synchronously when the box body 1 is raised. Since the fixed plate 2 42 is arranged in a stepped shape, the spring column 411 can be in contact with it and shake left and right when the fixed plate 2 42 moves. The swinging spring column 411 will drive the brush plate 1 412 to sweep away the impurities and dust remaining on the inner wall of the box body 1 and make them fall to the bottom of the inner wall of the box body 1, so that the device can clean the inner wall easily and quickly, avoiding the problem of excessive dust accumulation inside and affecting the filtering effect. At the same time, the staff can clean the inner wall of the device without manual operation when disassembling the device as a whole, thereby reducing the workload of the staff.

[0021] Preferably, the inner wall of the protective shell 22 is in contact with the outer surface of the pressing block 221, the bottom of the pressing block 221 is fixedly connected with a fixing column 222, the bottom of the fixing column 222 is fixedly connected with a sliding column 223, the bottom of the inner wall of the protective shell 22 is fixedly connected with a slide rail 24, the inner wall of the slide rail 24 is slidably connected with a sliding block 23, an oblique groove is provided on the front side of the sliding block 23, the inner wall of the oblique groove is in contact with the outer surface of the sliding column 223, a spring 231 is fixedly connected to the right side of the sliding block 23, and the right side of the spring 231 is fixedly connected to the left side of the inner wall of the protective shell 22. The staff of the present invention presses the pressing block 1 211 to move the outer shell 21 downward. The downward movement of the outer shell 21 will simultaneously drive the two pressing blocks 221 to move synchronously. The movement of the two pressing blocks will press the fixing column 1 222 inside the protective shell 22 downward. Since the sliding block 23 is provided with an inclined groove on the front side, the fixing column 1 222 will drive the sliding column 223 to press downward, so that the sliding block 23 will move in the opposite direction of the box body 1, so that the sliding block 23 is pulled out of the fixing hole provided in the box body 1, so that the device is free from the restriction. At this time, the staff can lift the outer shell 21 and lift the outer shell 21 out of the base 11, which is convenient for the staff to quickly disassemble the device. Compared with the previous cumbersome disassembly method, this method can make it more convenient and quick for the staff to disassemble the device, and can save a lot of time.

[0022] For example 2, please refer to Figure 5 - Fig. 9 The present invention is a quickly detachable human anti-poison filtering device. On the basis of the first embodiment, a telescopic column 33 is fixedly connected to the bottom of the movable column 2 41, and a hook 331 is rotatably connected to the outer surface of the telescopic column 33 through a pin shaft. A sliding ring 332 is slidably connected to the side of the outer surface of the telescopic column 33 close to the movable column 1 32, and a fixed plate 1 34 is fixedly connected to the side of the outer surface of the telescopic column 33 away from the sliding ring 332.

[0023] The inner wall of the fixed plate 134 is rotatably connected to a rotating rod 341. There are several fixed plates 134, and several fixed plates 134 are arranged in a circular array. The top of the rotating rod 341 is rotatably connected to a rope 1342, and the top of the rope 1342 is rotatably connected to the outer surface of the telescopic column 33. The present invention continuously lifts the box body 1, so that the telescopic column 33 drives the rope 1342 to pull, and the pulling of the rope 1342 causes the rotating rod 341 to rotate under the restriction of the fixed plate 134. Since the lower part of the rotating rod 341 is bent, when the rope 1342 is pulled, the bent side of the rotating rod 341 will continue to approach the inner wall of the moving column 132 until the several rotating rods 341 have the effect of supporting the inner wall of the moving column 132. At this time, continuing to lift the device upward will drive the moving column 132 to lift upward. When the limiting groove 321 provided in the moving column 132 is lifted to the position of the spring bead 311, the spring bead 311 will bounce into the limiting groove 32 1, it is restricted so that the moving column 1 32 is fixed. At this time, the device is moved downward. Since the fixed plate 1 34 is larger than the diameter of the moving column 1 32, the continuously descending telescopic column 33 will drive the hook 331 to continue to move downward until it is hung on the bottom of the telescopic column 33. The contraction of the telescopic column 33 will reset the rotating rod 341, canceling the restriction on the moving column 1 32, so that the device can be taken out as a whole. The device can prevent the staff from forgetting to completely disassemble the device or improperly operating the device when the device and the ventilation duct are not completely disassembled, causing damage to the connection between the device and the ventilation duct, and can also enable the device to be operated subsequently.

[0024] The two cleaning components 4 are symmetrically arranged with the fixed plate 42 as the center. The fixed plate 42 is fixedly connected to the bottom of the inner wall of the box body 1. The back of the fixed plate 42 is rotatably connected with a spring rotating plate 43. There are several spring rotating plates 43, and the several spring rotating plates 43 are arranged in a vertical array.

[0025] A collecting assembly 5 is arranged inside the box body 1, and there are two collecting assemblies 5. The two collecting assemblies 5 are symmetrically arranged with the spring rotating plate 43 as the center. The two collecting assemblies 5 contain the same parts. The collecting assembly 5 includes a lower pressure plate 51. The front side of the lower pressure plate 51 is fixedly connected to the back side of the moving column 2 41. There are two moving columns 41, and the right side of the moving column 2 41 located on the right side is rotatably connected with a rope 2 52.

[0026] The bottom of rope 52 contacts with fixed column 2 521, the right side of fixed column 2 521 is fixedly connected to the right side of the inner wall of box body 1, the bottom of the inner wall of box body 1 contacts with scraper 53, the top of scraper 53 is fixedly connected with connecting plate 522, the front of scraper 53 is fixedly connected with brush plate 2 531, the back of scraper 53 is fixedly connected with spring 2 54, a limiting groove is opened on the right side of scraper 53, the inner wall of limiting groove is slidably connected to the right side of the inner wall of box body 1, an assembly groove 55 is opened at the bottom of the inner wall of box body 1, the inner wall of assembly groove 55 is slidably connected with a spring pressing block 551, and the top of spring pressing block 551 is fixedly connected with a stopper 56. The present invention continuously lifts the box body 1 to make the lower pressure plate 51 contact with the spring pressing block 551 and press it downward. The spring pressing block 551 will drive the stopper 56 to move synchronously while pressing downward. The movement of the stopper 56 will release the restriction of the scraper 53. The scraper 53 after the restriction is released will be ejected under the action of the spring 2 54. The ejected scraper 53 will drive the brush plate 2 531 to move synchronously when it moves to the front end position of the brush plate 2 531, so as to push the dust and residue remaining on the bottom of the inner wall of the box body 1 and the dust scraped by the brush plate 1 412, and all the dust will be scraped into the dust box 111. The staff can directly remove the dust box 111 without manually collecting the dust, so that the device can collect the dust after the internal cleaning is completed, which is convenient for thorough cleaning of the inside of the device.

[0027] The method for using the quickly detachable human anti-poison filter device comprises the following steps: S1: dismantle the entire device; S2: lift and lower the device to clean the inside; S3: Disassemble the device and remove the dust box.

[0028] A specific application of the present embodiment is: when replacement is needed, the staff presses the pressing block 1 211 to move the outer shell 21 downward. The downward movement of the outer shell 21 will simultaneously drive the two pressing blocks 221 to move synchronously. The movement of the two pressing blocks will press the fixing column 1 222 inside the protective shell 22 downward. Since the sliding block 23 is provided with an inclined groove on the front side, the fixing column 1 222 will drive the sliding column 223 to press downward, so that the sliding block 23 will move in the opposite direction of the box body 1, so that the sliding block 23 is pulled out of the fixing hole provided in the box body 1, so that the device is freed from the restriction. At this time, the staff can lift the outer shell 21 and lift the outer shell 21 out of the base 11, so that the staff can quickly disassemble the device. Compared with the previous cumbersome disassembly method, this method can make it more convenient and quick for the staff to disassemble the device, and can save a lot of time.

[0029] By continuously lifting the box body 1, the telescopic column 33 drives the rope 1 342 to be pulled, and the pulling of the rope 1 342 causes the rotating rod 341 to rotate under the restriction of the fixed plate 1 34. Since the lower part of the rotating rod 341 is bent, when the rope 1 342 is pulled, the bent side of the rotating rod 341 will continue to approach the inner wall of the moving column 1 32 until a plurality of rotating rods 341 have the effect of supporting the inner wall of the moving column 1 32. At this time, continuing to lift the device upward will drive the moving column 1 32 to be lifted upward. When the limiting groove 321 provided in the moving column 1 32 is lifted to the position of the spring bead 311, the spring bead 311 will bounce into the limiting groove 321. The movable column 32 is restricted so that the movable column 32 is fixed. At this time, the device is moved downward. Since the fixed plate 34 is larger than the diameter of the movable column 32, the continuously descending telescopic column 33 will drive the hook 331 to continue to move downward until it is hung on the bottom of the telescopic column 33. The contraction of the telescopic column 33 will reset the rotating rod 341, canceling the restriction on the movable column 32, so that the device can be taken out as a whole. The device can prevent the staff from forgetting to completely disassemble the device or improperly operating the device when the device and the ventilation duct are not completely disassembled, causing damage to the connection between the device and the ventilation duct, and can also enable the device to be operated subsequently.

[0030] When the staff lifts the device as a whole, due to the action of the anti-mistouch component 3, the raising of the box body 1 will not drive the movable column 2 41 to move synchronously. However, the fixed plate 2 42 will move synchronously when the box body 1 is raised. Since the fixed plate 2 42 is arranged in a stepped shape, the spring column 411 can be in contact with it and swing left and right while the fixed plate 2 42 moves. The swinging spring column 411 will drive the brush plate 1 412 to sweep away the impurities and dust remaining on the inner wall of the box body 1, so that the brush plate 1 falls on the bottom of the inner wall of the box body 1, so that the device can clean the inner wall easily and quickly, avoiding the problem of excessive dust accumulation inside and affecting the filtering effect. At the same time, the staff can clean the inner wall of the device without manual operation when disassembling the device as a whole, thereby reducing the workload of the staff.

[0031] The box body 1 is continuously lifted up to make the lower pressure plate 51 contact with the spring pressing block 551 and press it down. The spring pressing block 551 will drive the stopper 56 to move synchronously while pressing down. The movement of the stopper 56 will release the restriction of the scraper 53. The scraper 53 after the restriction is released will be ejected under the action of the spring 2 54. The ejected scraper 53 will drive the brush plate 2 531 to move synchronously when it moves to the front end position of the brush plate 2 531, so as to push the dust and residue remaining on the bottom of the inner wall of the box body 1 and the dust scraped by the brush plate 1 412, and all the dust will be scraped into the dust box 111. The staff can directly remove the dust box 1 11 can be removed without manual dust collection, so that the device can collect dust after the internal cleaning is completed, which is convenient for thorough cleaning of the inside of the device. When resetting is required, the movable column 2 41 can drive the rope 2 52 to move by lowering the box body 1, and the scraper 53 is pulled back to its original position under the restriction of the fixed column 2 521. Since the stop block 56 is set in an arc shape, it will press down when the scraper 53 passes this position. After the scraper 53 passes, the stop block 56 will pop out again to limit the scraper 53. At the same time, when the scraper 53 moves to the tail of the brush plate 2 531, it will pull the moved brush plate 2 531 to reset.
