Description

TECHNICAL FIELD

[0001] The application relates to the technical field of computer equipment, in particular to a computer case with heat dissipation and dust prevention functions. BACKGROUND

[0002] The computer case, as a part of computer accessories, mainly serves to place and fix computer accessories and plays a supporting and protecting role. In addition, the computer case has the important role of shielding electromagnetic radiation.

[0003] The computer case needs to be provided with a heat dissipation mechanism to dissipate heat of the host accessories while protecting the host accessories, so as to avoid burning of the host accessories due to high temperature. For example, the Chinese patent with the publication number CN111103951A discloses a computer heat dissipation device installed in a computer case, which can realize continuous swinging of the heat dissipation fan when the heat dissipation fan moves up and down in the case, thereby achieving uniform blowing effect. The cold air entering the case through the heat dissipation air inlet hole can uniformly blow to the surface of the computer mainboard, thereby improving the heat dissipation effect of the computer mainboard.

[0004] According to the related technology in the above, the inventors believe that the following defects exist: when the computer case dissipates heat and protects the computer mainboard, the computer mainboard is mainly cooled by the heat dissipation fan. However, the computer case of the technology is not convenient for uniformly dissipating heat of the computer mainboard in all directions, but only can continuously dissipate heat of one side of the computer mainboard, which leads to the phenomenon that the computer mainboard is prone to have high temperature on one side and low temperature on the other side, and the computer mainboard is prone to heat accumulation, so that the temperatures of various components on the computer mainboard are different, which affects the heat dissipation efficiency of the computer mainboard. Long-term use will affect the use performance of the computer mainboard, and thus cannot guarantee the heat dissipation effect of the computer mainboard, thereby affecting the protection effect of the computer case on the computer mainboard. SUMMARY

[0005] In order to solve the problems that the computer case is not convenient for uniformly dissipating heat of the computer mainboard in all directions, but only can continuously dissipate heat of one side of the computer mainboard, which leads to the phenomenon that the computer mainboard is prone to have high temperature on one side and low temperature on the other side, and the computer mainboard is prone to heat accumulation, the application provides a computer case with heat dissipation and dust prevention functions.

[0006] The computer case with heat dissipation and dust prevention functions provided by the application adopts the following technical scheme:

[0007] The utility model provides a computer case with heat dissipation dustproof function, including case body and computer host fixed in the top wall of case body, be provided with processing mechanism for cooling, blowing and ventilation to computer host on the case body, be provided with power assembly for driving processing mechanism on the case body, processing mechanism includes cooling assembly, blowing assembly and ventilation assembly,

[0008] Power assembly includes spacing disc fixed under computer host, adjusting block fixed in the inside of spacing disc, motor switch set in the below of adjusting block and motor electrically connected with motor switch, adjusting block is fixedly connected with computer host, adjusting block can drive motor switch to start regularly,

[0009] Blowing assembly includes two heat dissipation boxes rotationally arranged in the inside of case body, fan blade rotationally arranged in the inside of heat dissipation box, rotation piece for rotationally driving fan blade, adjusting piece for rotationally adjusting two heat dissipation boxes and silencing piece for silencing two heat dissipation boxes, the inside of two heat dissipation boxes is provided with two fan blades,

[0010] Cooling assembly includes cooling box fixed under case body, cooling coil for storing cooling liquid, blowing piece for blowing cooling liquid outside cooling coil and control piece for controlling cooling liquid flow, adjusting block expands under high temperature, adjusting block shrinks under low temperature, adjusting block drives control piece to control the size of cooling liquid flow due to temperature change,

[0012] Through the above technical scheme, computer host can be cooled, blown and ventilated by processing mechanism, adjusting block in power assembly can detect the temperature of computer host, adjusting block can drive processing mechanism to drive regularly, cooling assembly, blowing assembly and ventilation assembly can cool, blow and ventilate computer host regularly, which can avoid burning of computer host due to high temperature and performance decline and starting difficulty of computer host due to low temperature, cooling coil can store cooling liquid to generate cooling air, blowing piece can blow the cooling air outside cooling coil, control piece can control the flow of cooling air into two heat dissipation boxes according to the temperature of computer host, which can ensure heat dissipation of computer host in the best state.

[0013] The mainframe commonly seen in the prior art computer case is usually composed of CPU, mainboard, memory, power supply, hard disk, display card, network card and optical drive and other accessories. Although the mainframe in the prior art is provided with a heat dissipation system to perform heat dissipation treatment on the intelligent accessories in the mainframe, the common heat dissipation system is usually directly installed on the main side where heat is generated by the CPU, and the fixed side of the CPU is tightly contacted to absorb and dissipate the generated heat. The optimized CPU heat dissipation system only performs continuous and uniform heat dissipation on one side of the CPU, while the other sides of the CPU are mainly cooled by the heat dissipation fins, and can only be slowly cooled by the temperature of the heat dissipation side. Although this heat dissipation method improves the heat dissipation effect of the CPU to a certain extent, it is easy to cause the CPU to generate heat accumulation phenomenon with high temperature on one side and low temperature on the other side. Because the CPU has storage, charging components and communication components working at the same time, the heat on the CPU is very balanced, which will generate strong heat on each part of the CPU, and the heat of other accessories on the mainframe will also be conducted to the CPU. Therefore, only the single side of the CPU is cooled, which will cause the CPU to generate heat accumulation phenomenon, but the CPU cooling is not uniform. Because the heat dissipation fins have a much slower heat dissipation speed than the heat dissipation system of the CPU, the temperature difference of each side of the CPU will be too large, which will accelerate the aging process of the CPU and other accessories. Because the CPU is a temperature-sensitive accessory, it will be deformed due to thermal expansion and cold contraction, which will cause poor contact or short circuit between the CPU and each accessory, and finally cause damage to the accessories. At the same time, the CPU will automatically reduce the working frequency to reduce the generation of heat. This frequency reduction operation will directly affect the processing speed and performance of the mainframe, causing slow response, speed reduction, blue screen, system crash or automatic restart and other phenomena. At the same time, in order to maintain the normal operation of the CPU, the heat dissipation system will work continuously to discharge heat. If the heat is accumulated in the CPU for a long time, the burden of the heat dissipation system will be increased, thereby increasing the energy consumption of the mainframe.

[0014] The computer case of the prior art is usually a small sealed box, and the ventilation of the computer case is very slow. The temperature of the computer host will become higher and higher during use. Therefore, when the heat dissipation mechanism performs circular blowing heat dissipation on the host, hot air will be formed due to the temperature of the host. Therefore, even if the prior art has the advantage of circular heat dissipation on the host, if hot air is blown, the host cannot be effectively cooled, the computer host cannot be quickly and continuously maintained at the optimal temperature, the speed and effect of the heat dissipation of the computer host cannot be effectively improved, and the traditional computer case does not have a cooling system. The traditional cooling method of the computer host is to cool the computer host by using a cooling machine and cooling liquid. However, this cooling method will cause water to be blown by the heat dissipation mechanism when the heat dissipation mechanism blows air on the computer host. The water will damage and interfere with the CPU, motherboard, memory, power supply, hard disk, graphics card, network card, optical drive and other accessories on the host, thereby reducing the service life of the host.

[0015] Moreover, the computer case of the prior art is usually a small sealed box, and the ventilation of the computer case is very slow. The temperature of the computer host will become higher and higher during use. Therefore, when the heat dissipation mechanism performs circular blowing heat dissipation on the host, hot air will be formed due to the temperature of the host. Therefore, even if the prior art has the advantage of circular heat dissipation on the host, if hot air is blown, the host cannot be effectively cooled, the computer host cannot be quickly and continuously maintained at the optimal temperature, the speed and effect of the heat dissipation of the computer host cannot be effectively improved, and the traditional computer case does not have a cooling system. The traditional cooling method of the computer host is to cool the computer host by using a cooling machine and cooling liquid. However, this cooling method will cause water to be blown by the heat dissipation mechanism when the heat dissipation mechanism blows air on the computer host. The water will damage and interfere with the CPU, motherboard, memory, power supply, hard disk, graphics card, network card, optical drive and other accessories on the host, thereby reducing the service life of the host.

[0016] Moreover, the computer case of the prior art is usually a small sealed box, and the ventilation of the computer case is very slow. The temperature of the computer host will become higher and higher during use. Therefore, when the heat dissipation mechanism performs circular blowing heat dissipation on the host, hot air will be formed due to the temperature of the host. Therefore, even if the prior art has the advantage of circular heat dissipation on the host, if hot air is blown, the host cannot be effectively cooled, the computer host cannot be quickly and continuously maintained at the optimal temperature, the speed and effect of the heat dissipation of the computer host cannot be effectively improved, and the traditional computer case does not have a cooling system. The traditional cooling method of the computer host is to cool the computer host by using a cooling machine and cooling liquid. However, this cooling method will cause water to be blown by the heat dissipation mechanism when the heat dissipation mechanism blows air on the computer host. The water will damage and interfere with the CPU, motherboard, memory, power supply, hard disk, graphics card, network card, optical drive and other accessories on the host, thereby reducing the service life of the host.

The noise problem of the heat dissipation mechanism during circumferential rotation is solved. The entire system does not need to set two or more power sources to realize multiple functions of the host during heat dissipation. The energy waste of the case is reduced. In addition, the wind power can be adjusted according to the temperature of the host, so as to control the temperature of the host at about forty degrees of the best temperature.

[0018] The design can make the four fan blades rotate to generate wind power in the two heat dissipation boxes through the blowing assembly.

[0037] In summary, the present application has at least one of the following beneficial technical effects:

[0038] 1. Pour the cooling liquid into the cooling coil to generate cooling air on the outer side of the cooling coil. Since the adjusting block is fixed to the bottom of the computer host, when the temperature of the computer host rises, the adjusting block will expand due to the high temperature, and when the temperature of the computer host decreases, the adjusting block will shrink due to the decrease in temperature. Therefore, the expansion and contraction of the adjusting block will change with the change in temperature of the computer host. When the adjusting block expands due to the temperature of the computer host, it will squeeze the soft plastic plate, the motor switch and the movable push plate. First, when the motor switch is squeezed, the motor will be started to make the whole processing mechanism work. When the adjusting block expands or shrinks due to the temperature, it will push the movable push plate to move up and down. Through the compression of the extension spring, the movable push plate and the two movable racks can be sequentially moved up and down, so as to drive the two movable gears and the two threaded rods to rotate, respectively, and then drive the two threaded blocks and the two adjusting plates to move left and right, respectively, so as to adjust the air inlet gap between the air inlet holes.

[0039] 2. When the temperature of the adjusting block rises, the air inlet gap between the adjusting plate and the air inlet hole becomes larger, and when the temperature of the adjusting block drops, the air inlet gap between the adjusting plate and the air inlet hole becomes smaller. The air inlet gap can be adjusted according to the temperature change of the computer host. When the temperature of the computer host is too high, the cold air enters the inner side of the two heat dissipation boxes through the two through holes and the two air inlet holes respectively due to the large air inlet gap, so as to enhance the subsequent heat dissipation effect of the computer host. When the temperature of the computer host drops, the cold air enters the inner side of the two heat dissipation boxes through the two through holes and the two air inlet holes respectively due to the small air inlet gap, so as to slow down the subsequent heat dissipation effect of the computer host. The computer host can be cooled at the best temperature state, which can avoid the burning of the computer host due to the high temperature, and can also avoid the performance decline and start-up difficulty of the computer host due to the low temperature. When the temperature of the computer host is about forty degrees in the normal range, the adjusting block does not change, and the adjusting block is separated from the motor switch due to the decrease of the temperature of the computer host, so that the motor stops driving and the whole processing mechanism stops running, which can avoid more energy consumption of the processing mechanism, and can also avoid the performance decline of the computer host due to the continuous heat dissipation of the processing mechanism, so as to ensure the stability of the heat dissipation of the computer host.

[0040] 3. When the motor starts, it will drive the drive shaft, transmission gear, two connecting gears, two connecting shafts and two movable vanes in turn to rotate to generate wind power, which can blow away the cold air outside the cooling coil. With the wind power blowing into the two air inlet holes in the rotating disc through the multiple air holes in the cooling coil, the rotation of the two movable vanes can quickly blow away the cold air on the left and right sides of the cooling coil. Before the cold air enters the two air inlet holes, the two water absorbing cotton boards will adsorb and filter the moisture in the cold air, removing the moisture in the cold air to prevent the moisture in the cold air from entering the computer case body and affecting the computer host. The filtered cold air will flow into the two through holes and the two heat sinks through the two air inlet holes respectively. At the same time, by moving the adjusting plate left and right, the floating speed of the cold air entering the two heat sinks can be controlled. When the drive shaft rotates, it will drive the rotating disc, two water absorbing cotton boards, two heat sinks, two cylindrical gears, two movable rods, and an internal bevel gear in turn to rotate, which will further drive two movable rods, two first bevel gears, two second bevel gears, two first universal joints, two driving wheels, two transmission belts, two driven wheels, two second universal joints, four extension rods and four fan universal joints to rotate, which will further drive four fan blades to rotate to generate wind power. At the same time, the continuous entry of cold air into the inside of the two heat sinks and the mixing of wind power can form cool air. Through the rotation of the four fan blades, the cool air can be blown on the computer host through the multiple heat dissipation holes on the inside of the two heat sinks, which can heat the computer host. Through the rotation of the four fan blades, the left and right sides as well as the top and bottom of the computer host can be evenly cooled, avoiding the phenomenon of heat accumulation on one side of the computer host with high temperature and the other side with low temperature, ensuring the use performance of the computer host. At the same time, when the two heat sinks rotate, combined with the rotation of the four fan blades, the outside of the computer host can be evenly cooled in a circle, which can cool the computer host in all directions, ensure the temperature consistency of the computer host in all directions, and strengthen the cooling effect of the computer host, further avoiding the phenomenon of heat accumulation of the computer host;

[0041] 4. When the four fan universal joints rotate, the four eccentric gears also rotate, because the four eccentric gears are meshed with the four limiting gears, so when the four limiting gears rotate, through the connection and cooperation between the two first universal joints, the two second universal joints, the four extension rods, the four fan universal joints, the four eccentric gears, the four limiting gears, the four limiting blocks, the four fixed blocks and the four limiting grooves, the four fan blades can swing up and down when rotating, which can ensure the cooling effect of the four fan blades on the computer host, so that every position of the computer host can be cooled, and the cooling and heat dissipation effect of the four fan blades on the computer host can be enhanced, so that the temperature of each position of the computer host is not the same, and the heat aggregation phenomenon of the computer host is avoided as much as possible, the computer host is evenly cooled, and when the two heat dissipation boxes rotate on the inner side of the case body, through the cooperation between the ten sets of buffer springs, the ten sets of storage grooves, the ten buffer plates, the damper and the ten sound-absorbing cots, the noise generated when the two heat dissipation boxes rotate can be silenced, and when the heat dissipation box is attached to the sound-absorbing cotton, the buffer spring is in a compressed state, and then the buffer spring and the sound-absorbing cotton can absorb and silence the noise, so as to ensure the use environment of the case body and the computer host.

[0042] 5. Because the inner bevel gear is meshed with the outer bevel gear, when the inner bevel gear rotates, the outer bevel gear, the fan rod and the reverse blade will also rotate to generate suction, the wind power inside the case body can be sucked into the inner side of the fixed box through the air inlet pipe, the wind power can be blown out through the multiple ventilation holes inside the dust cover, the wind power inside the case body can be blown upwards, and then the inside of the case body can be ventilated and replaced, which can further enhance the heat dissipation effect of the computer host, the fixed box has a dustproof effect when ventilating and replacing, dust and particles cannot enter the inside of the fixed box and the case body when ventilating and replacing, and the computer host is not affected by dust and stains, when the fan rod rotates, the power wheel, the power belt, the follower and the rotating rod will also rotate, through the connection and cooperation between the crank, the connecting rod, the connecting plate, the two limiting blocks and the two limiting grooves, the sponge can move left and right above the dust cover, the dust cover can be brushed and dusted, dust and particles cannot accumulate above the dust cover to block the ventilation holes, the case body can be ventilated and replaced, the computer case can uniformly cool the computer host in all directions, the temperature of one side of the computer host is not high and the temperature of the other side is not low, the heat aggregation phenomenon of the computer host is avoided, the temperature of each component on the computer host is not the same, the cooling efficiency of the computer host is ensured, and the protection effect of the computer case on the computer host is enhanced.

[0064] The implementation principle of the computer case with the heat dissipation and dust prevention functions is as follows:

[0065] (1) open the cover 22 can be cooled by the cooling liquid through the water pipe 21 into the inner side of the cooling coil 20, can make the outside of the cooling coil 20 produce cold air, because the adjustment block 59 is fixed at the bottom of the computer host 2, so when the temperature of the computer host 2 rises, the adjustment block 59 will expand due to high temperature, at the same time, when the temperature of the computer host 2 decreases, the adjustment block 59 will shrink due to the decrease of temperature, so the expansion and shrinkage of the adjustment block 59 will change with the change of the temperature of the computer host 2;

[0066] (2) when the adjustment block 59 expands due to the temperature of the computer host 2, it will cause extrusion to the soft plastic plate 32, the motor switch 31 and the movable push plate 30. First, when the motor switch 31 is extruded, the motor 5 will be started, so that the whole processing mechanism runs. At the same time, when the adjustment block 59 expands or shrinks due to temperature, it will push the movable push plate 30 to move up and down, and through the compression of the extension spring 61, the movable push plate 30 and the two movable racks 33 will be driven to move up and down in turn, and then the two movable gears 34 and the two threaded rods 35 will be driven to rotate in turn, and then the two threaded blocks 36 and the two adjusting plates 37 will be driven to move left and right, so as to adjust the air inlet gap between the adjusting plate 37 and the air inlet hole;

[0067] (3) when the temperature of the adjustment block 59 rises, the air inlet gap between the adjusting plate 37 and the air inlet hole will become larger, and when the temperature of the adjustment block 59 decreases, the air inlet gap between the adjusting plate 37 and the air inlet hole will become smaller. The air inlet gap can be adjusted according to the change of the temperature of the computer host 2. When the temperature of the computer host 2 is too high, the cold air will pass through the two through holes and the two air inlet holes into the inside of the two heat dissipation boxes 8 respectively due to the too large air inlet gap, so as to enhance the subsequent heat dissipation effect of the computer host 2;

[0068] (4) when the temperature of the computer host 2 decreases, the cold air will pass through the two through holes and the two air inlet holes into the inside of the two heat dissipation boxes 8 respectively due to the too small air inlet gap, so as to slow down the subsequent heat dissipation effect of the computer host 2, so as to ensure that the computer host 2 is cooled at the best temperature state. It can avoid the burning of the computer host 2 due to high temperature, and also avoid the performance decline and start-up difficulty of the computer host 2 due to low temperature;

[0069] (5) at the same time, when the temperature of the computer host 2 is about forty degrees in the normal range, the adjustment block 59 will not change, and at the same time, the adjustment block 59 will shrink and separate from the motor switch 31 due to the decrease of the temperature of the computer host 2, so that the motor 5 stops driving, and the whole processing mechanism stops running, which can avoid more energy consumption of the processing mechanism, and also can avoid the performance decline of the computer host 2 due to the continuous cooling of the processing mechanism, so as to ensure the stability of the cooling of the computer host 2;

[0070] (6) When the motor 5 starts, it will drive the drive shaft 6 and the transmission gear 25 to rotate in turn, and then drive the two connecting gears 26, the two connecting shafts 27 and the two movable vanes 28 to rotate, respectively. When the movable vanes 28 rotate, wind power is generated, which can blow away the cold air outside the cooling coil 20. The wind power blows into the two air inlet holes in the rotating disc 7 through the multiple air holes in the cooling coil 20. Through the rotation of the two movable vanes 28, the cold air on the left and right sides of the cooling coil 20 can be quickly blown away. Before the cold air enters the two air inlet holes, the two water-absorbing cotton plates 29 will adsorb and filter the moisture in the cold air, removing the moisture in the cold air to avoid the moisture in the cold air from entering the case body 1 and affecting the computer host 2. The filtered cold air will flow into the two through holes and the two heat sinks 8 through the two air inlet holes, respectively. At the same time, by adjusting the left and right movement of the adjusting plate 37, the flow speed of the cold air into the two heat sinks 8 can be controlled.

[0071] (7) When the drive shaft 6 rotates, it will drive the rotating disc 7, the two water-absorbing cotton plates 29, the two heat sinks 8, the two cylindrical gears 10, the two movable rods 11 and the inner bevel gear 38 to rotate in turn. When the two cylindrical gears 10 rotate, they will drive the two movable rods 11 and the two first bevel gears 12 to rotate, respectively. When the two first bevel gears 12 rotate, they will drive the two second bevel gears 13, the two first universal joints 14 and the two driving wheels 15 to rotate, respectively. When the two driving wheels 15 rotate, they will drive the two driving wheels 15, the two transmission belts 16, the two driven wheels 17 and the two second universal joints 18 to rotate, respectively. When the two first universal joints 14 and the two second universal joints 18 rotate, they will drive the four telescopic rods 62, the four fan universal joints 63 and the four fan blades 19 to rotate and generate wind power. At the same time, the continuous entry of cold air into the inside of the two heat sinks 8 and the wind power mixing can form cool air. Through the rotation of the four fan blades 19, the cool air can be blown on the computer host 2 through the multiple heat dissipation holes on the inside of the two heat sinks 8, and then the computer host 2 can be cooled. Through the rotation of the four fan blades 19, the left and right sides as well as the top and bottom of the computer host 2 can be evenly cooled, avoiding the phenomenon of heat accumulation on one side of the computer host 2 with high temperature and the other side with low temperature, and ensuring the use performance of the computer host 2;

[0072] (8) When the four fan joints 63 rotate, they will also drive the four eccentric gears 64 to rotate, because the four eccentric gears 64 are meshed with the four limit gears 65, so when the four limit gears 65 rotate, through the connection and cooperation between the two first universal joints 14, the two second universal joints 18, the four extension rods 62, the four fan joints 63, the four eccentric gears 64, the four limit gears 65, the four limit blocks, the four fixed blocks and the four limit grooves, the four fan blades 19 can have an up and down swinging effect when rotating, which can ensure the cooling effect of the four fan blades 19 on the computer host 2, so that every position of the computer host 2 can be cooled, and the cooling and heat dissipation effect of the four fan blades 19 on the computer host 2 can be enhanced, so that the temperature of each position of the computer host 2 is not the same, and the phenomenon of heat accumulation of the computer host 2 is avoided as much as possible, and the uniform range effect of the computer host 2 is realized;

[0073] (9) When the two heat dissipation boxes 8 rotate, they can rotate with the four fan blades 19, so that the outside of the computer host 2 can be uniformly cooled in a circle, and the computer host 2 can be cooled in all directions, so that the temperature of the computer host 2 in all directions is consistent, and the cooling effect of the computer host 2 can be enhanced, and the phenomenon of heat accumulation of the computer host 2 can be further avoided;

[0074] (10) When the two heat dissipation boxes 8 rotate on the inside of the case body 1, through the cooperation between the ten sets of buffer springs 53, the ten sets of storage grooves, the ten buffer plates 54, the dampers and the ten sound-absorbing cottons 55, the noise generated when the two heat dissipation boxes 8 rotate can be treated, when the heat dissipation box 8 is in close contact with the sound-absorbing cotton 55, the buffer spring 53 will be in a compressed state, and then the noise can be absorbed and treated through the buffer spring 53 and the sound-absorbing cotton 55, so as to ensure the use environment of the case body 1 and the computer host 2;

[0075] (11) Because the inner bevel gear 38 is meshed with the outer bevel gear 39, when the inner bevel gear 38 rotates, it will in turn drive the outer bevel gear 39, the fan rod 40 and the reverse blade 41 to rotate, and when the reverse blade 41 rotates, it will generate suction, and then the wind power on the inside of the case body 1 can be sucked into the inside of the fixed box 42 through the air inlet pipe 52, and then the wind power can be blown out through the multiple ventilation holes on the inside of the dust cover 43, so that the wind power on the inside of the case body 1 can be blown upwards, and then the inside of the case body 1 can be ventilated and exchanged, and the cooling effect of the computer host 2 can be further enhanced;

[0076] (12) The fixed box 42 has a dustproof effect when ventilating, avoiding dust and particles from entering the inside of the fixed box 42 and the computer case body 1 when ventilating, ensuring the hygiene of the computer host 2, avoiding the computer host 2 from being affected by dust and stains, and the fan blade rod 40 rotating will drive the power wheel 44, the power belt 45, the follower wheel 46 and the rotating rod 47 to rotate. Because the crank 48 is hinged to the connecting rod 49, the connecting rod 49 is hinged to the connecting plate 50, and the connecting plate 50 is limited on the dust cover 43 by two limiting sliding blocks 58 and two limiting sliding grooves, when the rotating rod 47 rotates, the sponge 51 can move left and right above the dust cover 43 through the connection between the crank 48, the connecting rod 49, the connecting plate 50, the two limiting sliding blocks 58 and the two limiting sliding grooves, and then the dust cover 43 can be wiped and dusted, avoiding dust and particles from accumulating above the dust cover 43 to block the ventilation hole, ensuring the ventilation effect of the computer case body 1, achieving the purpose of ventilating and dustproofing the computer case body 1, and wiping the dust cover 43 with the sponge 51 can avoid noise.
