In this way, external dust will not move toward the inside of the pulse controller under the blowing of the airflow.
[0018] 2. The present invention sets an auxiliary mechanism so that when the second blade rotates, it will touch the contact block. In this way, when the second blade is reset, it can only return to the initial position due to the limitation of the pressing plate and cannot shift inward, thereby avoiding airflow aggregation. Once the gathered airflow flows to the outside of the pulse controller, the overheated airflow contacts the dust, which will cause adverse reactions.
[0019] 3. The present invention provides a third spring, which can exert a pulling force on the second magnetic block. When the rotating plate rotates, under the pulling force of the third spring, the second magnetic block will approach the third spring. Such a design can effectively prevent the third spring from being in a stretched state for a long time, thereby extending the service life of the third spring and ensuring that it can operate stably under more working conditions.
[0020] 4. The present invention sets a first magnetic block and a second magnetic block. When the heat dissipation airflow passes through the two, the attraction between them will be weakened, thereby enabling the second magnetic block to slide upward. After the heat is reduced, the first magnetic block and the second magnetic block resume the attraction state, thereby realizing automatic closing of the partition and effectively ensuring the stability and safety of the internal environment of the equipment.

DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0032] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0033] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0034] Embodiment 1: Referring to FIGS. 1 to 5 , the present invention provides a technical solution: a pulse controller with dust explosion-proof function, comprising a pulse controller 1, an explosion-proof shell 2 is clamped on the left side of the pulse controller 1, an exhaust net 5 is fixedly connected to the middle end of the top of the pulse controller 1, a guide plate 3 is fixedly connected to the side of the top of the pulse controller 1 away from the exhaust net 5, and a protective shell 4 is fixedly connected to the right side of the top of the guide plate 3, and further comprising:
[0035] The diversion mechanism 6 includes a fixing frame 601, the left side of the fixing frame 601 is fixedly connected to the guide plate 3, the front and back sides of the fixing frame 601 are fixedly connected to support plates 602, the middle end of the top of the support plate 602 is fixedly connected to a first clamping plate 603, the bottom of the first clamping plate 603 is fixedly connected to a first blade 605 through a fixed shaft, the top of the support plate 602 is fixedly connected to a second clamping plate 604 on a side away from the first clamping plate 603, the bottoms of the two groups of second clamping plates 604 are both rotatably connected to second blades 612 through a first rotating shaft, two groups of fixing rods 608 are arranged on the top of the second blade 612, and the diversion effect of the airflow can be achieved by arranging the second blade 612 through the rotation angle of the second blade 612, the top right sides of the two groups of second blades 612 are fixedly connected to second fixing blocks 611, and the sides of the two groups of second fixing blocks 611 close to the first blade 605 are fixedly connected Pull rod 610, a first fixed block 609 is fixedly connected to the right side of the top of the first blade 605, two groups of fixed rods 608 are fixedly connected on both sides of the first fixed block 609 close to the second fixed block 611, and the two groups of fixed rods 608 are fixedly connected to the first spring 607 on the side away from the first fixed block 609. By setting the first spring 607, the first spring 607 can pull the second blade 612 to rotate after being stretched. When the pulling force disappears, the first spring 607 can perform a reset movement, driving the second blade 612 to perform the same movement. The outer walls of the two groups of fixed rods 608 are fixedly connected with a dustproof shell 606, and the two groups of first springs 607 are fixedly connected to the pulling rod 610 on one side away from the fixed rod 608. The first spring 607 can change the angle of the second blade 612 through the telescopic force of the first spring 607, thereby changing the flow trajectory of the airflow.
[0036] The working principle of this embodiment is as follows: when the pulse controller 1 carries out heat dissipation operation, the hot air flow will be discharged from the top, and then flow to the bottom of the exhaust net 5 and touch it, and then flow from the exhaust net 5 to the bottom of the guide plate 3. In view of the arc-shaped structure of the guide plate 3, the airflow will change its direction when flowing through the guide plate 3, and turn from the original moving path toward the top to flow to the right, and then flow to the fixed frame 601, and pass through the inside of the fixed frame 601, and come into contact with the side walls of the first blade 605 and the second blade 612. If the flow rate and flow velocity of the airflow are large, it will push the second blade 612 to rotate outward by 30 degrees on the second clamping plate 604, causing the airflow to change its direction again during the flow process. When the second blade 612 rotates, it will pull the pulling rod 610 to move away from the fixing rod 608, so that the first spring 607 is pulled and begins to stretch, thereby ensuring that the second blade 612 can smoothly achieve angular rotation.
[0037] Embodiment 2: Please refer to Figures 6-7. On the basis of Embodiment 1, the present invention provides a technical solution: it also includes an auxiliary mechanism 7, the auxiliary mechanism 7 includes an arc-shaped plate 701, the bottom of the arc-shaped plate 701 is fixedly connected to the top of the second clamping plate 604, a rotating rod 702 is arranged at the middle end of the top of the arc-shaped plate 701, the rotating rod 702 penetrates the arc-shaped plate 701, and a contact block 703 is fixedly connected to the bottom of the rotating rod 702, the bottom of the contact block 703 contacts the top of the second clamping plate 604, a groove 707 is opened on the right side of the inner wall of the arc-shaped plate 701, and a second spring 705 is fixedly connected to the groove wall of the groove 707, and the second spring A receiving plate 706 is fixedly connected to one side of 705 away from the groove wall of the groove 707, and the outer wall of the receiving plate 706 is in contact with the inner wall of the arc plate 701 on all sides. A pressing plate 704 is fixedly connected to one side of the contact block 703 away from the second blade 612. By setting the pressing plate 704, one side of the arc plate 701 can be contacted, so that the contact block 703 cannot continue to move after the reset rotation is completed, thereby limiting the rotation distance of the second blade 612. The bottom of the pressing plate 704 is in contact with the top of the second clamping plate 604, and the side of the contact block 703 close to the second blade 612 is in contact with the second rotation axis.
[0038] The working principle of this embodiment is as follows: during the rotation of the two groups of second blades 612, the contact block 703 rotates synchronously therewith, thereby driving the pressing plate 704 to rotate at the same angle, causing the rotating rod 702 to start rotating under the drive of the contact block 703. When the second blade 612 is reset, the contact block 703 is reset and continues to drive the pressing plate 704 to perform a reset movement. During reset, the pressing plate 704 contacts the receiving plate 706, and the receiving plate 706 exerts a pressing effect on the second spring 705. Subsequently, the second spring 705 rebounds, making it impossible for the pressing plate 704 to continue moving, thereby ensuring that the second blade 612 does not rotate inward.
[0039] Embodiment 3: Please refer to Figures 8-9. On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: it also includes a blocking mechanism 8, the blocking mechanism 8 includes a protective shell 801, the left side of the protective shell 801 is fixedly connected to the right side of the guide plate 3, the left side of the guide plate 3 is fixedly connected to the right side of the protective shell 4, and the right side of the inner wall of the protective shell 801 is fixedly connected with two groups of vertical rods 802, and the sides of the two groups of vertical rods 802 close to the protective shell 801 are fixedly connected to the inner wall of the protective shell 801, and the two groups of vertical rods 802 are connected to the inner wall of the protective shell 801. Two sets of partitions 804 are rotatably connected to each other through two third rotating shafts on the sides close to each other, the top and bottom of the inner wall of the protective shell 801 are fixedly connected to the bottom plate 803, the two sets of bottom plates 803 are fixedly connected to the sides close to each other with positioning rods 810, and the two sets of positioning rods 810 are rotatably connected to the rotating plate 809 on the sides close to each other through the fourth rotating shaft, and the inner walls of the two sets of positioning rods 810 are provided with sliding rods 807, and the upper and lower ends of the two sets of sliding rods 807 are fixed to the top and bottom of the inner wall of the positioning rods 810. The outer walls of the two sets of slide bars 807 are respectively fixedly connected with the first magnetic blocks 805, and the tops of the two sets of first magnetic blocks 805 are both provided with second magnetic blocks 806. By providing the first magnetic blocks 805 and the second magnetic blocks 806, the heat of the airflow can be used to reduce the attraction between the first magnetic blocks 805 and the second magnetic blocks 806, so as to ensure the normal opening and closing function of the partition 804. The two sets of second magnetic blocks 806 are respectively slidably connected with the two sets of slide bars 807, and the two sets of second magnetic blocks 806 are far away. A third spring 808 is fixedly connected to one side away from the rotating plate 809. By setting the third spring 808, the second magnetic block 806 can be pulled, thereby ensuring that when the second magnetic block 806 moves toward the third spring 808, the stretching distance of the third spring 808 can be reduced, thereby improving the service life. The two groups of third springs 808 are fixedly connected to the top of the rotating plate 809 on one side away from the second magnetic block 806, and the two groups of rotating plates 809 are fixedly connected to the partition 804.
[0040] The working principle of this embodiment is as follows: when the airflow flows out from the first blade 605 and the second blade 612 and passes through the partition 804, the driving force of the airflow acts on the partition 804, causing it to start rotating. During the rotation of the partition 804, the rotating plate 809 is driven to rotate, thereby causing the third spring 808 to be stretched when the rotating plate 809 rotates. At the same time, due to the heating effect of the hot air on the first magnetic block 805 and the second magnetic block 806, the magnetic force of the two is weakened, so the third spring 808 drives the second magnetic block 806 to slide upward on the sliding rod 807, so that the second magnetic block 806 gradually moves away from the first magnetic block 805. At this time, the rotating plate 809 and the positioning rod 810 are in a vertical state, the partition 804 is fully opened, and the airflow can flow outward, thereby blowing away the dust around the protective shell 801.
