The end of the transmission spring is fixedly connected to the inner wall of the back surface of the outer shell. The top end of the U-shaped circular rod penetrates through the outer shell and is slidably connected to the outer shell.

[0010] Further, anti-blocking mechanisms are respectively provided on the two U-shaped circular rods. The anti-blocking mechanism includes a connecting rod hinged to the U-shaped circular rod. A U-shaped limiting frame is fixedly installed on the front surface of the outer shell. A U-shaped fixing plate is slidably installed inside the U-shaped limiting frame. The end of the connecting rod is hinged to the U-shaped fixing plate. A plurality of scraping plates are fixedly installed inside the U-shaped fixing plate. The top ends of the plurality of scraping plates are all in contact with the dust filter plate.

[0011] Further, a telescopic mechanism is provided on the bidirectional threaded rod. The telescopic mechanism includes two internal thread blocks threadedly sleeved on the bidirectional threaded rod. One side of the two internal thread blocks close to each other is respectively hinged with a movable rod. One end of the two movable rods close to each other is hinged with a display screen.

[0012] Further, an adaptation mechanism is provided on the bidirectional threaded rod. The adaptation mechanism includes a rectangular fixing plate fixedly sleeved on the bidirectional threaded rod. Two movable adaptation plates are slidably sleeved on the bidirectional threaded rod. Two adaptation springs are sleeved on the bidirectional threaded rod. One side of the two adaptation springs close to each other is fixedly connected to the rectangular fixing plate. One end of the two adaptation springs away from each other is fixedly connected to the two movable adaptation plates respectively.

[0013] Furthermore, a limiting mechanism is provided on the shell, and the limiting mechanism includes a convex limiting groove opened on the top of the bottom plate, and two L-shaped plates are slidably installed in the convex limiting groove. Limiting springs are fixedly installed on the left and right sides of the shell respectively, and the ends of the two limiting springs that are away from each other are fixedly connected to the two L-shaped plates respectively, and the sides of the two L-shaped plates that are close to each other are in contact, and the tops and bottoms of the two L-shaped plates are fixedly installed with inclined plates respectively.

[0014] Furthermore, the procurement document classification device based on NLP technology has the following steps:

[0015] S1: When in use, the driving motor is started, and the driving motor drives the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the two internal threaded blocks to approach each other, and the internal threaded blocks drive the two movable rods to approach each other. The movable rod drives the display screen to move upward. The display screen will contact the inclined plate during the rising process. Under the action of the inclined surface of the inclined plate, the display screen will push the two inclined plates in the shell to move to both sides. At this time, the two inclined plates in the shell will drive the two L-shaped plates to move away from each other until the display screen extends out of the shell and stops moving. After the display screen moves out of the shell, the display screen will always contact the two L-shaped plates. At this time, the tensile deformation value of the two limit springs is the maximum. When in use, the display screen is moved out of the shell to facilitate observation of the progress of file processing. After use, the display screen is moved back into the shell again to ensure that dust will not fall on the display screen;

[0016] S2: The rotation of the two-way threaded rod will also drive several turbine blades in the two circular turbine boxes to rotate. The rotation of several turbine blades will draw air into the circular turbine box through the holes on the dust filter plate, the sealing block and the air inlet pipe. The gas entering the circular turbine box will be discharged from the air outlet. During the exhaust process, the gas in the shell will accumulate more and more, and the air pressure in the shell will also increase. Since the limit spring has been stretched to the maximum value, the gas will enter the two convex cylinders through the perforated circular plate at this time. The gas will push the two sealing circular plates away from each other. At this time, the exhaust spring is stretched and deformed. When the two sealing circular plates contact the inner walls of the convex cylinder that are away from each other, the air outlet holes on the convex cylinder will be exposed, and the gas will be discharged from the air outlet holes and bring out the heat in the shell. When the gas is discharged from the air outlet holes, dust can be prevented from blocking the air outlet holes. After use, since the two-way threaded rod no longer rotates, the exhaust spring will pull the sealing circular plate back to its original position under the action of elastic force to prevent dust from entering the shell from the air outlet holes.

[0017] S3: During the process of the display screen rising to the specified usage position, when the internal thread blocks on the bidirectional threaded rod approach each other, they will contact and push the two movable adaptation plates closer to each other. The two movable adaptation plates will cause the two adaptation springs to undergo compressive deformation. When the two internal thread blocks approach each other and leave the threads on the bidirectional threaded rod, they will be subjected to the thrust of the two adaptation springs. At this time, the two internal thread blocks will be in a state of semi-disengagement from the threads. At this time, the bidirectional threaded rod will not drive the internal thread blocks to move. At this time, the internal thread blocks will also reach the specified working position. At the same time, the internal thread blocks will not affect the normal rotation of the bidirectional threaded rod. At this time, the heat dissipation work inside the housing will proceed normally;

[0018] S4: During the rotation of several turbine blades, they will contact the air outlet extending into the air outlet. The trapezoidal transmission block will be contacted by the turbine blades under the action of the inclined surface and then leave the air outlet. After the corresponding turbine blade leaves the trapezoidal transmission block, the trapezoidal transmission block will return to the air outlet again under the elastic force of the transmission spring. At this time, the trapezoidal transmission block will drive the U-shaped round rod to perform a reciprocating motion. The U-shaped round rod will drive the connecting rod to move. The connecting rod will drive the U-shaped fixing plate to slide up and down in the U-shaped limiting frame. The U-shaped fixing plate will drive several scraping plates to scrape the dust filter plate up and down, preventing impurities and dust from falling on the dust filter plate during the air extraction process and causing blockage of the holes in the dust filter plate.

[0019] The present invention has the following beneficial effects:

[0020] (1) For the procurement document classification device based on NLP technology of the present invention, when in use, start the driving motor. The driving motor drives the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the two internal thread blocks to approach each other. The internal thread blocks drive the two movable rods to approach each other. The movable rods drive the display screen to move upward. During the rising process of the display screen, it will contact the inclined plate. Under the action of the inclined surface of the inclined plate, the display screen will push the two inclined plates inside the housing open and move them to both sides. At this time, the two inclined plates inside the housing will drive the two L-shaped plates to move away from each other until the display screen extends out of the housing and then stops moving. After the display screen is moved out of the housing, the display screen will always be in contact with the two L-shaped plates. At this time, the tensile deformation value of the two limiting springs is the largest. When in use, moving the display screen out of the housing is convenient for observing the process of processing documents, and at the same time, it also has the effect of ventilating and dissipating heat for the display screen. After use, moving the display screen back into the housing can ensure that no dust will fall on the display screen and prevent dust from entering the display screen and affecting the electronic components inside the display screen;

[0021] (2) In the procurement document classification device based on NLP technology of the present invention, when the bidirectional threaded rod rotates, it will also drive the rotation of several turbine blades in two circular turbine boxes. The rotation of several turbine blades will draw air into the circular turbine boxes through the holes on the dust filter plate, the sealing blocks, and the air inlet pipe. The gas entering the circular turbine boxes will be discharged from the air outlet. During the exhaust process, the gas in the housing will accumulate more and more, and the air pressure in the housing will also increase. Since the stretching of the limit spring has reached the maximum value, at this time, the gas will enter the two convex cylinders through the perforated circular plate. The gas will push the two sealing circular plates away from each other. At this time, the exhaust spring will undergo a stretching deformation. When the two sealing circular plates contact the inner walls of the convex cylinders that are moving away from each other, the air outlet holes on the convex cylinders will be exposed. The gas will be discharged from the air outlet holes and take out the heat in the housing, thus achieving the heat dissipation effect. When the gas is discharged from the air outlet holes, it can prevent dust from blocking the air outlet holes. After use, since the bidirectional threaded rod stops rotating, the exhaust spring will pull the sealing circular plates back to their original positions under the action of elastic force to prevent dust from entering the housing through the air outlet holes;

[0022] (3) In the procurement document classification device based on NLP technology of the present invention, during the process of the display screen rising to the designated use position, when the internal threaded blocks on the bidirectional threaded rod approach each other, they will contact and push the two movable adaptation plates closer to each other. The two movable adaptation plates will cause the two adaptation springs to undergo a compressive deformation. When the two internal threaded blocks approach each other and leave the threads on the bidirectional threaded rod, they will be pushed by the two adaptation springs. At this time, the two internal threaded blocks will be in a semi-disengaged state from the threads. At this time, the bidirectional threaded rod will not drive the internal threaded blocks to move. At this time, the internal threaded blocks will also reach the designated working positions, and at the same time, the internal threaded blocks will not affect the normal rotation of the bidirectional threaded rod. At this time, the heat dissipation work inside the housing will proceed normally;

[0023] (4) In the procurement document classification device based on NLP technology of the present invention, during the rotation of several turbine blades, they will contact the air outlet extending into the air outlet. The trapezoidal transmission block will be pushed by the turbine blades under the action of the inclined plane and leave the air outlet. After the corresponding turbine blade leaves the trapezoidal transmission block, the trapezoidal transmission block will return to the air outlet again under the elastic force of the transmission spring. At this time, the trapezoidal transmission block will drive the U-shaped round rod to perform a reciprocating motion. The U-shaped round rod will drive the connecting rod to move. The connecting rod will drive the U-shaped fixing plate to slide up and down in the U-shaped limiting frame. The U-shaped fixing plate will drive several scraping plates to scrape the dust filter plate up and down, preventing impurities and dust from falling onto the dust filter plate during the air extraction process and causing blockage of the holes in the dust filter plate, thereby affecting the heat dissipation effect of the housing.

[0024] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 - Figure 8 As shown, the present invention is a classification method for a procurement document classification device based on NLP technology, comprising a base plate 1, a housing 101 is arranged on the top of the base plate 1, the housing 101 comprises a bidirectional threaded rod 102 rotatably mounted in the housing 101, a drive motor 103 is fixedly mounted on the right side of the housing 101, the right side of the bidirectional threaded rod 102 extends outside the housing 101 and is fixedly connected to the output shaft of the drive motor 103, and further comprises:

[0038] Two circular turbine boxes 104 are rotatably installed on the bidirectional threaded rod 102, and the two circular turbine boxes 104 are fixedly connected to the bottom inner wall of the outer casing 101. A number of turbine blades 105 are fixedly installed on the bidirectional threaded rod 102, and the several turbine blades 105 are respectively adapted to the two circular turbine boxes 104. Two air outlets 106 are respectively opened on the outer walls of the two circular turbine boxes 104, and two air inlet pipes 107 are respectively fixedly installed on the outer walls of the two circular turbine boxes 104. Two sealing blocks 108 are fixedly installed on the front inner wall of the outer casing 101, and the front ends of the two air inlet pipes 107 are respectively fixedly connected to the two sealing blocks 108, and the two air inlet pipes 107 are respectively communicated with the two sealing blocks 108, and two dust filter plates 109 are fixed on the front of the outer casing 101.

[0039] like Figure 3 As shown, two exhaust mechanisms 2 are arranged on the outer shell 101, and the exhaust mechanism 2 includes a convex cylinder 201 fixedly installed on the right side of the outer shell 101, the convex cylinder 201 is communicated with the outer shell 101, and a plurality of air outlet holes 202 are opened on the outer wall of the convex cylinder 201, a perforated circular plate 203 is fixedly installed in the convex cylinder 201, an exhaust spring 204 is fixedly installed on the right side of the perforated circular plate 203, a sealing circular plate 205 is fixedly installed on the right end of the exhaust spring 204, and the sealing circular plate 205 is slidably connected to the convex cylinder 201.

[0040] The gas will enter into the two convex cylinders 201 through the perforated circular plate 203. The gas will push the two sealing circular plates 205 away from each other. At this time, the exhaust spring 204 will undergo tensile deformation. When the two sealing circular plates 205 contact the inner walls of the convex cylinder 201 that are away from each other, the air outlet holes 202 on the convex cylinder 201 will be exposed. The gas will be discharged from the air outlet holes 202 and take out the heat inside the housing 101, thus achieving the heat dissipation effect. When the gas is discharged from the air outlet holes 202, it can prevent dust from blocking the air outlet holes 202. After use, since the bidirectional threaded rod 102 stops rotating, the exhaust spring 204 will pull the sealing circular plate 205 back to its original position under the action of elastic force to prevent dust from entering the housing 101 from the air outlet holes 202.

[0041] As Figure 4 shown, two transmission mechanisms 3 are arranged inside the housing 101. The transmission mechanism 3 includes a U-shaped circular rod 301 slidably installed inside the housing 101. A trapezoidal transmission block 302 is fixedly installed at the front end of the U-shaped circular rod 301. The front end of the trapezoidal transmission block 302 extends into the air outlet 106. A transmission spring 303 is sleeved on the U-shaped circular rod 301. The front end of the transmission spring 303 is fixedly connected to the trapezoidal transmission block 302. The end of the transmission spring 303 is fixedly connected to the inner wall of the back surface of the housing 101. The top end of the U-shaped circular rod 301 penetrates through the housing 101 and is slidably connected to the housing 101.

[0042] After the corresponding turbine blade 105 leaves the trapezoidal transmission block 302, the trapezoidal transmission block 302 will return to the air outlet 106 again under the action of the elastic force of the transmission spring 303. At this time, the trapezoidal transmission block 302 will drive the U-shaped circular rod 301 to move reciprocally.

[0043] As Figure 5 and Figure 6 shown, anti-blocking mechanisms 4 are respectively arranged on the two U-shaped circular rods 301. The anti-blocking mechanism 4 includes a connecting rod 401 hinged on the U-shaped circular rod 301. A U-shaped limiting frame is fixedly installed on the front surface of the housing 101. A U-shaped fixing plate 402 is slidably installed inside the U-shaped limiting frame. The end of the connecting rod 401 is hinged to the U-shaped fixing plate 402. A plurality of scraping plates 403 are fixedly installed inside the U-shaped fixing plate 402. The top ends of the plurality of scraping plates 403 are all in contact with the dust filtering plate 109.

[0044] The U-shaped circular rod 301 will drive the connecting rod 401 to move. The connecting rod 401 will drive the U-shaped fixing plate 402 to slide up and down inside the U-shaped limiting frame. The U-shaped fixing plate 402 will drive the plurality of scraping plates 403 to scrape the dust filtering plate 109 up and down, preventing impurities and dust from falling on the dust filtering plate 109 during the air extraction process and causing blockage of the holes of the dust filtering plate 109, thus affecting the heat dissipation effect of the housing 101.

[0045] As Figure 2 As shown, a telescopic mechanism 5 is provided on the bidirectional threaded rod 102, and the telescopic mechanism 5 includes two internal thread blocks 501 threadedly sleeved on the bidirectional threaded rod 102, and movable rods 502 are hingedly installed on the sides of the two internal thread blocks 501 close to each other, and a display screen 503 is hingedly installed on the ends of the two movable rods 502 close to each other, and limiting plates 504 are fixedly installed on the front and back sides of the two internal thread blocks 501, and the ends of the several limiting plates 504 away from each other extend into the shell 101 and are slidably connected to the shell 101.

[0046] The bidirectional threaded rod 102 will drive the two internal thread blocks 501 to approach each other, the internal thread block 501 will drive the two movable rods 502 to approach each other, and the movable rods 502 will drive the display screen 503 to move upward. When in use, the display screen 503 is moved out of the shell 101 to facilitate observation of the progress of file processing, and it also serves the effect of ventilation and heat dissipation of the display screen 503. After use, the display screen 503 is moved back into the shell 101 to ensure that dust does not fall on the display screen 503, thereby preventing dust from entering the display screen 503 and affecting the electronic components in the display screen 503.

[0047] like Figure 2 As shown, an adaptation mechanism 6 is provided on the bidirectional threaded rod 102, and the adaptation mechanism 6 includes a rectangular fixed plate 601 fixedly sleeved on the bidirectional threaded rod 102, two movable adaptation plates 602 are slidably sleeved on the bidirectional threaded rod 102, and two adaptation springs 603 are sleeved on the bidirectional threaded rod 102, and the sides of the two adaptation springs 603 close to each other are fixedly connected to the rectangular fixed plate 601, and the ends of the two adaptation springs 603 away from each other are respectively fixedly connected to the two movable adaptation plates 602.

[0048] When the internal thread blocks 501 on the bidirectional threaded rod 102 approach each other, they will contact and push the two movable adaptive plates 602 towards each other. The two movable adaptive plates 602 will cause the two adaptive springs 603 to be compressed and deformed. When the two internal thread blocks 501 approach each other and leave the threads on the bidirectional threaded rod 102, they will be pushed by the two adaptive springs 603. At this time, the two internal thread blocks 501 will be in a semi-disconnected state.

[0049] like Figure 2 As shown, a limiting mechanism 7 is provided on the shell 101, and the limiting mechanism 7 includes a convex limiting groove 701 opened on the top of the bottom plate 1, and two L-shaped plates 702 are slidably installed in the convex limiting groove 701, and limiting springs 703 are fixedly installed on the left and right sides of the shell 101 respectively, and the ends of the two limiting springs 703 that are away from each other are fixedly connected to the two L-shaped plates 702 respectively, and the sides of the two L-shaped plates 702 that are close to each other are in contact, and the tops and bottoms of the two L-shaped plates 702 are fixedly installed with inclined plates 704 respectively.

[0050] The display screen 503 will contact the inclined plate 704 during the rising process. Under the action of the inclined surface of the inclined plate 704, the display screen 503 will push the two inclined plates 704 in the shell 101 open and move to both sides. At this time, the two inclined plates 704 in the shell 101 will drive the two L-shaped plates 702 to move away from each other until the display screen 503 extends out of the shell 101 and stops moving.

[0051] like Figure 1-8 A procurement document classification device based on NLP technology is shown, and the method steps are as follows:

[0052] S1: When in use, the drive motor 103 is started, and the drive motor 103 drives the bidirectional threaded rod 102 to rotate. The bidirectional threaded rod 102 drives the two internal thread blocks 501 to approach each other, and the internal thread blocks 501 drive the two movable rods 502 to approach each other. The movable rods 502 drive the display screen 503 to move upward. The display screen 503 will contact the inclined plate 704 during the upward process. Under the action of the inclined surface of the inclined plate 704, the display screen 503 will push the two inclined plates 704 in the shell 101 to move to both sides. At this time, the shell 1 The two inclined plates 704 in the housing 101 will drive the two L-shaped plates 702 to move away from each other until the display screen 503 extends out of the housing 101 and then stops moving. After the display screen 503 moves out of the housing 101, the display screen 503 will always be in contact with the two L-shaped plates 702. At this time, the tensile deformation values ​​of the two limit springs 703 are maximum. When in use, the display screen 503 is moved out of the housing 101 to facilitate observation of the progress of file processing. After use, the display screen 503 is moved back into the housing 101 to ensure that dust will not fall on the display screen 503.

[0053] S2: The rotation of the bidirectional threaded rod 102 will also drive the rotation of several turbine blades 105 in the two circular turbine boxes 104. The rotation of several turbine blades 105 will draw air into the circular turbine box 104 through the holes on the dust filter plate 109, the sealing block 108 and the air inlet pipe 107. The gas entering the circular turbine box 104 will be discharged from the air outlet 106. During the exhaust process, the gas in the shell 101 will accumulate more and more, and the air pressure in the shell 101 will also increase. Since the stretching of the limit spring 703 has reached the maximum value, the gas will enter the two convex cylinders 201 through the perforated circular plate 203, and the gas will push The two sealing circular plates 205 move away from each other, and the exhaust spring 204 is stretched and deformed. When the two sealing circular plates 205 contact the inner walls of the convex cylinder 201 that move away from each other, the air outlet holes 202 on the convex cylinder 201 are exposed, and the gas is discharged from the air outlet holes 202 and takes out the heat in the housing 101. When the gas is discharged from the air outlet holes 202, dust can be prevented from blocking the air outlet holes 202. After use, since the two-way threaded rod 102 no longer rotates, the exhaust spring 204 will pull the sealing circular plates 205 back to their original positions under the action of elastic force to prevent dust from entering the housing 101 from the air outlet holes 202.

[0054] S3: When the display screen 503 rises to the designated use position, the internal thread blocks 501 on the bidirectional threaded rod 102 will contact and push the two movable adaptable plates 602 to approach each other, and the two movable adaptable plates 602 will cause the two adaptable springs 603 to be compressed and deformed. When the two internal thread blocks 501 approach each other and leave the threads on the bidirectional threaded rod 102, they will be pushed by the two adaptable springs 603. At this time, the two internal thread blocks 501 will be in a semi-disengaged state. At this time, the bidirectional threaded rod 102 will not drive the internal thread blocks 501 to move. At this time, the internal thread blocks 501 will also reach the designated working position. At the same time, the internal thread blocks 501 will not affect the normal rotation of the bidirectional threaded rod 102.

8. A method for using a procurement document classification device based on NLP technology, using the procurement document classification device based on NLP technology as claimed in claim 7, characterized in that: The steps are as follows: S1: When in use, the drive motor (103) is started, and the drive motor (103) drives the bidirectional threaded rod (102) to rotate. The bidirectional threaded rod (102) drives the two internal threaded blocks (501) to approach each other, and the internal threaded blocks (501) drive the two movable rods (502) to approach each other. The movable rods (502) drive the display screen (503) to move upward. The display screen (503) contacts the inclined plate (704) during the upward process. Under the action of the inclined surface of the inclined plate (704), the display screen (503) pushes the two inclined plates (704) in the housing (101) to move to both sides. At this time, the housing (101) is moved upward. The two inclined plates (704) in the housing (101) will drive the two L-shaped plates (702) to move away from each other until the display screen (503) extends out of the housing (101) and then stops moving. After the display screen (503) moves out of the housing (101), the display screen (503) will always be in contact with the two L-shaped plates (702). At this time, the tensile deformation values ​​of the two limit springs (703) are maximum. When in use, the display screen (503) is moved out of the housing (101) to facilitate observation of the progress of file processing. After use, the display screen (503) is moved back into the housing (101) to ensure that dust does not fall on the display screen (503). S2: The rotation of the bidirectional threaded rod (102) will also drive the rotation of the plurality of turbine blades (105) in the two circular turbine boxes (104). The rotation of the plurality of turbine blades (105) will draw air into the circular turbine box (104) through the holes on the dust filter plate (109), the sealing block (108) and the air inlet pipe (107). The gas entering the circular turbine box (104) will be discharged from the air outlet (106). During the exhaust process, the gas in the housing (101) will accumulate more and more, and the air pressure in the housing (101) will also increase. Since the limit spring (703) has been stretched to the maximum value, the gas will enter the two convex cylinders (201) through the perforated circular plate (203), and the gas will push The two sealing circular plates (205) move away from each other, and at this time, the exhaust spring (204) is stretched and deformed. When the two sealing circular plates (205) contact the inner walls of the convex cylinder (201) that move away from each other, the air outlet holes (202) on the convex cylinder (201) are exposed, and the gas is discharged from the air outlet holes (202) and takes out the heat in the housing (101). When the gas is discharged from the air outlet holes (202), dust can be prevented from blocking the air outlet holes (202). After use, since the bidirectional threaded rod (102) no longer rotates, the exhaust spring (204) will pull the sealing circular plates (205) back to their original positions under the action of elastic force to prevent dust from entering the housing (101) from the air outlet holes (202); S3: During the process of the display screen (503) rising to the specified usage position, when the internal thread blocks (501) on the bidirectional threaded rod (102) approach each other, they will contact and push the two movable adaptor plates (602) to approach each other. The two movable adaptor plates (602) will cause the two adaptor springs (603) to undergo compressive deformation. When the two internal thread blocks (501) approach each other and leave the threads on the bidirectional threaded rod (102), they will be pushed by the two adaptor springs (603). At this time, the two internal thread blocks (501) will be in a state of semi-disengagement from the threads. At this time, the bidirectional threaded rod (102) will not drive the internal thread block (501) to move. At this time, the internal thread block (501) will also reach the specified working position. At the same time, the internal thread block (501) will not affect the normal rotation of the bidirectional threaded rod (102). At this time, the heat dissipation work inside the housing (101) will proceed normally; S4: During the rotation of several turbine blades (105), they will contact the air outlet (106) extending into the air outlet (106). The trapezoidal transmission block (302) will be pushed by the contact of the turbine blade (105) under the action of the inclined plane and leave the air outlet (106). After the corresponding turbine blade (105) leaves the trapezoidal transmission block (302), the trapezoidal transmission block (302) will return to the air outlet (106) again under the elastic force of the transmission spring (303). At this time, the trapezoidal transmission block (302) will drive the U-shaped round rod (301) to perform reciprocating motion. The U-shaped round rod (301) will drive the connecting rod (401) to move. The connecting rod (401) will drive the U-shaped fixing plate (402) to slide up and down in the U-shaped limiting frame. The U-shaped fixing plate (402) will drive several scraping plates (403) to scrape the dust filter plate (109) up and down, preventing impurities and dust from falling onto the dust filter plate (109) during the air extraction process and causing blockage of the holes in the dust filter plate (109).
