DETAILED DESCRIPTION

[0046] The following description will be made in conjunction with the accompanying drawings: Figure 1 - the accompanying drawings Figure 10 Further detailed description will be made to the present application. Example 1:

In addition, the heat dissipation block 3 is provided with a dustproof assembly 6 and a cleaning assembly 7. Among them, the dustproof assembly 6 is used to reduce the dust entering from the outside to the inside of the box 1, and the cleaning assembly 7 is used to clean the dustproof assembly 6, so as to reduce the maintenance frequency of the dustproof assembly 6.

[0048] Referring to Figure 3The dustproof assembly 6 comprises a mounting rack 601 connected with the heat dissipation block 3 through buckling, wherein the mounting rack 601 is in the shape of "C" in cross section and is inserted into the side of the heat dissipation block 3. The part of the mounting rack 601 between the heat dissipation block 3 and the back plate of the cabinet 1 is provided with a trigger groove 8, and the groove bottom of the trigger groove 8 is fixedly connected with a trigger spring 602. In addition, the mounting rack 601 is provided with a recess, and the recess is slidably connected with a dustproof plate 603. The side of the dustproof plate 603 close to the back plate of the cabinet 1 is fixedly connected with a connecting plate 604, and the outer surface of the connecting plate 604 is fixedly connected with the end of the trigger spring 602. The side of the dustproof plate 603 close to the cabinet door 2 is fixedly connected with a bracket plate 605, wherein the bracket plate 605 is matched with the shape of the dustproof plate 603, and the end of the bracket plate 605 is fixedly connected with a buffer block 606. When the cabinet door 2 is closed, the cabinet door 2 extrudes the buffer block 606 to push the dustproof plate 603 to slide close to the groove bottom of the trigger groove 8, so that the trigger spring 602 is deformed to store kinetic energy.

[0049] With reference to Figure 3 , Figure 4 The dustproof plate 603 is integrally formed with six dustproof strips 607 corresponding to the heat dissipation strips 4, and the dustproof strips 607 cover the corresponding heat dissipation strips 4. The cross section of the dustproof strip 607 is in the shape of "C", the heat dissipation holes 5 and the axis of the dustproof strip 607 are located in the same horizontal plane, and the ventilation holes 9 are formed in the two opposite inner walls of the dustproof strip 607. In this way, when the external airflow flows into the heat dissipation holes 5, it first contacts the arc surface of the dustproof strip 607 and then flows along the arc surface of the dustproof strip 607 to the ventilation holes 9. In addition, the arc-shaped inner wall of the dustproof strip 607 is provided with a dust blocking groove 10 extending along the length direction of the dustproof strip 607, and the groove width of the dust blocking groove 10 is between 0.5-1mm. When the external airflow flows along the arc surface of the dustproof strip 607, the dust carried in the airflow will be affected by the centrifugal force and flow into the dust blocking groove 10 under the action of inertia, thereby reducing the amount of dust carried by the airflow when passing through the ventilation holes 9.

[0050] With reference to Figure 1 , Figure 5 , Figure 6The arc-shaped block 608 is recessed towards the inside of the box 1, and the side of the arc-shaped block 608 close to the box door 2 is smoothly connected with the surface of the box 1. The cleaning assembly 7 comprises a fixed sleeve 701 fixedly connected with the mounting frame 601, and the side of the fixed sleeve 701 is connected with the surface of the arc-shaped block 608 in the box 1 through buckling. In addition, the side of the fixed sleeve 701 close to the box door 2 is fixedly connected with a leakage prevention block 702, wherein the shape of the leakage prevention block 702 is matched with the support plate 605 and the dustproof plate 603, and the end of the leakage prevention plate away from the arc-shaped block 608 is fixedly connected with a sealing strip 703, wherein the sealing strip 703 is made of soft rubber material, and the sealing strip 703 is in abutment with the support plate 605 when the box door 2 is closed, and the sealing strip 703 is relatively slid with the support plate 605 when the box door 2 is opened and the dustproof plate 603 is pushed to slide by the trigger spring 602, so as to gradually abut with the dustproof plate 603.

[0051] The gap plate 704 is fixedly connected in the fixed sleeve 701 and is parallel to the leakage prevention plate, and the shape of the gap plate 704 is matched with the support plate 605 and the dustproof plate 603, wherein the gap plate 704 is matched with the dust blocking groove 10 of the dustproof plate 603, so that the dust blocking groove 10 forms a small hole between the dustproof plate 603 and the fixed sleeve 701 at the gap plate 704. When the external airflow enters the dustproof plate 603, the dust in the dust blocking groove 10 can be blown into the fixed sleeve 701 from the small hole through the slit effect.

[0052] Referring to Figure 5 , Figure 7 The opening is communicated with the fixed sleeve 701, and the fixed sleeve 701 is fixedly connected with two plug-in plates 705, and the two plug-in plates 705 are fixedly connected with the two opposite inner walls of the arc-shaped block 608 through bolts.

[0053] Referring to Figure 6 , Figure 7 , Figure 8The sliding groove 11 is formed on the plug-in plate 705, the inner wall of the sliding groove 11 away from the support plate 605 is fixedly connected with a reset spring 12, the end of the reset spring 12 is fixedly connected with a sliding block 706 made of metal, and the sliding block 706 is slidingly arranged in the sliding groove 11. In addition, the sliding block 706 is rotatably connected with two groups of sliding wheels 707, and the sliding wheels 707 abut against the inner wall of the sliding groove 11. In addition, the side of the plug-in plate 705 close to the dustproof plate 603 is provided with a first guide groove 13 in communication with the sliding groove 11, the dustproof plate 603 is fixedly connected with a guide block 708 extending into the first guide groove 13, and the guide block 708 is fixedly connected with a first permanent magnet 14, and the surface of the first permanent magnet 14 is coated with a protective layer. When the box door 2 is opened and triggers the sliding of the dustproof plate 603 and the guide block 708 slides along the first guide groove 13, the first permanent magnet 14 is magnetically attracted to the sliding block 706, and the sliding block 706 slides towards the dustproof plate 603 while pulling the reset spring 12, so that the reset spring 12 is deformed and stretched.

[0054] The sliding block 706 is provided with a rotating groove 15, and a rotating roller 709 is rotatably connected in the rotating groove 15. In addition, the side wall of the rotating roller 709 is fixedly connected with a plurality of cleaning sheets 710, and the cleaning sheets 710 are fixedly connected with a number of protrusions matched with the number of the dust strips 607, so that the protrusions of the cleaning sheets 710 can extend into the dust strips 607 of the dustproof plate 603. In addition, the protrusions are fixedly connected with a plurality of plastic scraping hairs 711, and the distribution of the scraping hairs 711 is matched with the distribution of the dust blocking grooves 10 of the dust strips 607, so that the scraping hairs 711 can extend into the dust blocking grooves 10. When the rotating roller 709 slides along the sliding groove 11 away from the fixed sleeve 701, the cleaning sheets 710 gradually extend out of the cabinet 1, so that the external airflow can flow along the arc-shaped block 608 and push the cleaning sheets 710 to rotate, thereby forming a low pressure in the fixed sleeve 701 at this time, so as to suck the dust in the dust blocking grooves 10 on the dustproof plate 603 out of the small holes to the outside. In addition, the cleaning sheets 710 rotate under the action of the external airflow, so that the dust adsorbed on the surface of the cleaning sheets 710 falls off under the action of centrifugal force.

[0055] The gear groove 16 is arranged in the fixed sleeve 701, and the inner wall of the gear groove 16 is rotationally connected with the first gear 712. Meanwhile, the side of the fixed sleeve 701 close to the dustproof plate 603 is provided with the driving groove 17 communicated with the gear groove 16, and the first gear 712 partially extends into the driving groove 17. In addition, the dustproof plate 603 and the support plate 605 are fixedly connected with the rack 714 extending into the driving groove 17, and the rack 714 is engaged with the first gear 712. The rotating roller 709 is rotationally connected with the sliding block 706 after penetrating the gear groove 16, and the rotating roller 709 is partially axially sleeved with the second gear 713. When the sliding block 706 slides towards the guide block 708 close to the dustproof plate 603, the sliding block 706 carries the second gear 713 to synchronously slide towards the dustproof plate 603, so that the second gear 713 is engaged with the first gear 712. When the cabinet door 2 is opened, the dustproof plate 603 drives the second gear 713 to rotate through the first gear 712, and drives the cleaning leaf 710 of the rotating roller 709 to rotate.

[0056] The implementation principle of the embodiment 1 of the present application is as follows: when the cabinet door 2 is closed, the cabinet door 2 pushes the buffer block 606 of the dustproof plate 603, forces the dustproof plate 603 to slide towards the back plate of the cabinet 1 with the dustproof strip 607. At this time, the dustproof strip 607 completely covers the heat dissipation strip 4, the ventilation hole 9 is dislocated with the heat dissipation hole 5 of the heat dissipation strip 4, a physical isolation layer is formed, and large particles of dust are blocked from entering the cabinet 1. The external airflow needs to flow along the arc-shaped inner wall of the dustproof strip 607 (centrifugal force is generated), and the dust is thrown into the dust blocking groove 10 due to inertia, the filtered airflow enters the cabinet 1 through the ventilation hole 9, and primary dust prevention is realized. At the same time, the dustproof plate 603 slides to compress the trigger spring 602, and the elastic potential energy is stored for subsequent cleaning. And, the sliding block 706 is located away from the dustproof plate 603 under the action of the return spring 12, so that the cleaning leaf 710 partially extends out of the cabinet 1, the external airflow pushes the exposed cleaning leaf 710 to rotate, and the dust adsorbed is thrown off by using the centrifugal force. At the same time, the gap plate 704 generates negative pressure at the small hole of the dust blocking groove 10 (slit effect), and the residual dust in the groove is sucked into the fixed sleeve 701 and discharged to the outside.

[0057] When the box door 2 is opened, the trigger spring 602 releases energy, and pushes the dustproof plate 603 to slide reversely and reset. The guide block 708 of the dustproof plate 603 drives the first permanent magnet 14 to slide along the first guide slot 13, and the metal sliding block 706 is attracted to the fixed sleeve 701, and the reset spring 12 is stretched; at the same time, the sliding block 706 carries the rotating roller 709 and the cleaning sheet 710 to slide towards the fixed sleeve 701, so that the second gear 713 is engaged with the first gear 712. And in the process of sliding of the dustproof plate 603, the rack 714 of the dustproof plate 603 drives the first gear 712 to rotate, drives the engaged second gear 713 to rotate, and finally drives the rotating roller 709 to rotate, so that the cleaning sheet 710 performs cleaning work on the dustproof plate 603. Embodiment 2

The sliding block 706 has magnetism, and the sliding block 706 and the second permanent magnet 19 repel each other, and the sliding block 706 and the first permanent magnet 14 attract each other. In addition, the sliding block 706, the first permanent magnet 14 and the second permanent magnet 19 are coated with a protective coating.

[0059] The implementation principle of the embodiment 2 is that when the dustproof plate 603 slides, the second permanent magnet 19 on the guide block 708 is close to the sliding slot 11. Because the second permanent magnet 19 and the sliding block 706 repel each other, the sliding block 706 is pushed to move away from the fixed sleeve 701, so that the second gear 713 and the first gear 712 are separated in advance to avoid invalid friction. In the initial stage of resetting of the dustproof plate 603, the first permanent magnet 14 attracts the sliding block 706 to slide (same as the embodiment 1), so as to ensure that the gears are quickly engaged, and at the same time, the second permanent magnet 19 is away from the sliding slot 11 with the dustproof plate 603, the magnetic repulsion disappears, the resetting resistance of the sliding block 706 is reduced, and at the same time, the part of the cleaning sheet 710 extending out of the box body 1 is increased, so as to increase the stress area of the cleaning sheet 710.
