Description

Technical Field

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

[0002] As a part of computer accessories, the computer case mainly plays the role of placing and fixing various computer accessories, and plays a supporting and protective role. In addition, the computer case plays the important role of shielding electromagnetic radiation.

[0003] The computer case, while protecting the host accessories, also needs to be provided with a heat dissipation mechanism to dissipate the heat of the host accessories to prevent the host accessories from being burned out due to over-high temperature. For example, in the related art, a Chinese patent with publication number CN111103951A proposes a computer heat dissipation device installed in a computer case, which has a heat dissipation fan that completes one swing, and the heat dissipation fan performs continuous swinging when moving up and down in the case to achieve a uniform blowing effect. The cold air entering the case through the heat dissipation air inlet can be evenly blown to the surface of the computer motherboard, thereby improving the heat dissipation effect on the computer motherboard.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the computer case performs heat dissipation protection on the computer motherboard, the computer case is mainly cooled down by a heat dissipation fan, but the computer case of this technology is not convenient for performing all-round and uniform heat dissipation on the computer motherboard, and can only perform continuous heat dissipation treatment on one side of the computer motherboard, which causes the computer motherboard to easily have a high temperature on one side and a low temperature on the other side, and makes the computer motherboard prone to heat accumulation, and makes the temperatures of various components on the computer motherboard different, which affects the heat dissipation efficiency of the computer motherboard. Long-term use will affect the performance of the computer motherboard, and thus the heat dissipation effect of the computer motherboard cannot be guaranteed, which further affects the protection effect of the computer case on the computer motherboard. Summary of the invention

[0005] In order to solve the problem that a computer case is not convenient for uniformly dissipating heat for a computer mainboard in all directions, and can only continuously dissipate heat on one side of the computer mainboard, which causes the computer mainboard to easily have a high temperature on one side and a low temperature on the other side, making the computer mainboard prone to heat accumulation, the present application provides a computer case with heat dissipation and dustproof functions.

[0006] The present application provides a computer case with heat dissipation and dust prevention functions, which adopts the following technical solution: A computer case with heat dissipation and dustproof functions, comprising a case body and a computer host fixed to the top wall of the case body, the case body is provided with a processing mechanism for cooling, blowing and ventilating the computer host, the case body is provided with a power component for driving the processing mechanism, and the processing mechanism includes a cooling component, a blowing component and a ventilating component; The power assembly includes a limit plate fixed below the computer host, an adjustment block fixed inside the limit plate, a motor switch arranged below the adjustment block, and a motor electrically connected to the motor switch. The adjustment block is fixedly connected to the computer host, and the adjustment block can drive the motor switch to start at a fixed time. The blowing assembly includes two heat sinks rotatably arranged inside the chassis body, fan blades rotatably arranged inside the heat sinks, a rotating member for driving the fan blades to rotate, an adjusting member for rotating the two heat sinks, and a silencer for silencing the two heat sinks, and two fan blades are arranged inside the two heat sinks; The cooling assembly includes a cooling box fixed under the chassis body, a cooling coil for storing coolant, a blowing member for blowing cold air outside the cooling coil, and a control member for controlling the flow of cold air. The regulating block expands at high temperatures and contracts at low temperatures, so that the regulating block can drive the control member due to temperature changes to control the flow of cold air. The ventilation assembly includes a fixed box fixed on the top of the chassis body, a reverse blade rotatably arranged on the inner side of the fixed box, a dust cover movably arranged on the top of the fixed box, a driving member for rotating the reverse blade, and a scraping brush member for scraping and removing dust from the top of the dust cover.

[0007] By adopting the above technical scheme, the computer host can be cooled, blown and ventilated by the processing mechanism, the adjustment block in the power component can detect the temperature of the computer host, the adjustment block can drive the processing mechanism to drive regularly, and the cooling component, the blowing component and the ventilation component can perform regular cooling, blowing and ventilation on the computer host to avoid the computer host from burning out due to excessively high temperature, and at the same time avoid the phenomenon of performance degradation and difficulty in starting the computer host due to excessively low temperature. The cooling coil can store the coolant to generate cold air, and at the same time, the cold air outside the cooling coil can be blown away by the blowing member, and the cold air can be blown into two heat sinks. At the same time, the flow rate of cold air entering the two heat sinks can be controlled by the control member according to the temperature of the computer host. When the temperature of the computer host is too high, the flow rate of cold air can be increased, and when the temperature of the computer host is too low, the flow rate of cold air can be reduced, so as to ensure that the computer host performs heat dissipation in the best state.

[0008] In the prior art, a common host in a computer case is usually composed of accessories such as a CPU, a motherboard, a memory, a power supply, a hard disk, a graphics card, a network card, and an optical drive. Although a heat dissipation system is provided in the host in the prior art to dissipate heat for the intelligent accessories in the host, a common heat dissipation system is usually directly installed on the main side where the CPU heat is generated, and the heat generated is absorbed and dissipated by the heat dissipation system in close contact with a fixed side of the CPU. At the same time, an optimized CPU heat dissipation system only dissipates heat continuously and evenly on one side of the CPU, while the other sides of the CPU are mainly dissipated by fitting heat sinks, and can only be slowly cooled by the temperature of the heat dissipation surface. 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 have a high temperature on one side and a low temperature on the other side, resulting in heat accumulation. 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 to various parts of the CPU. The amount of heat, and the heat of other accessories on the host will also be conducted to the CPU. Therefore, only cooling one side of the CPU will cause heat accumulation in the CPU, but it will make the CPU heat dissipation uneven, because the heat sink is far less than the heat dissipation speed of the CPU by the heat dissipation system, which will make the temperature difference of each surface on the CPU too large, and will accelerate the aging process of the CPU and other accessories. Because the CPU is a temperature-sensitive accessory, it will deform due to thermal expansion and contraction, and then cause poor contact or short circuit between the CPU and various accessories, and finally cause damage to the accessories. At the same time, the CPU will automatically reduce the operating frequency to reduce heat generation. This frequency reduction operation will directly affect the processing speed and performance of the host, resulting in sluggish response of running programs, reduced running speed, blue screen, freeze or automatic restart, etc. At the same time, in order to maintain the normal operation of the CPU, the heat dissipation system will continue to work to discharge heat. If heat accumulates inside the CPU for a long time, the burden on the heat dissipation system will increase, thereby increasing the energy consumption of the host.

[0009] At the same time, the heat dissipation mechanism of the optimized computer case has the advantage of circular heat dissipation for the host, but the heat dissipation mechanism is prone to friction with the case to generate noise when performing circular rotation, affecting the working environment of the computer case, and it is not convenient to control the wind while the host is performing circular heat dissipation, it is not convenient to adjust the size of the circular wind force of the heat dissipation mechanism according to the temperature of the host, it is not convenient to automatically keep the host at the optimal working temperature, and not every circular rotating heat dissipation mechanism can be used in the computer case. For example, the host of the case of this technology is set in the center of the case, and the host is mainly fixed and supported by the inner top wall of the case, and The height of the host is equal to the height inside the case. Therefore, even if the heat dissipation mechanism can rotate the host in a circle in the computer case, because the height of the host is too high, it cannot be guaranteed that each accessory area on the host can receive accurate air blowing from the heat dissipation mechanism. The only way to achieve the auxiliary air blowing effect in other accessory areas is through the movement of wind. Moreover, although each computer case is provided with a ventilation mechanism, a good ventilation and dust prevention mechanism is not provided. Therefore, dust and stains are easily blown into the inner side of the computer case during ventilation of the ventilation mechanism of the traditional computer case, and are easily blocked in the vents after long-term use, which will cause the ventilation mechanism to be blocked.

[0010] Moreover, in the prior art, a computer case 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 when it is in use. Therefore, when the heat dissipation mechanism performs circular air blowing to dissipate heat to the host, hot air will be generated due to the temperature of the host. Therefore, even if there is an advantage of performing circular heat dissipation on the host in the prior art, if hot air is blown, the effective heat dissipation effect of the host cannot be achieved, the computer host cannot be quickly and continuously maintained at the optimal temperature, and the speed and effect of heat dissipation of the computer host cannot be effectively improved. There is no cooling system on the traditional computer case, and the traditional computer host cooling method is also to cool down through a cooler and a coolant. However, this cooling method will cause the heat dissipation mechanism to generate moisture when blowing air to the computer host. If the moisture is blown on the host, it 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.

[0011] This design can continuously cool the wind. When the heat dissipation mechanism performs circumferential heat dissipation on the host, the wind can be kept at a low temperature through the combination of wind and cold air, and the moisture in the wind can be adsorbed to prevent the moisture from being blown onto the host with the wind. The heat dissipation mechanism can perform circumferential heat dissipation on the host while keeping the wind at a low temperature to ensure the speed and effect of the heat dissipation of the host by the heat dissipation mechanism. Moreover, this setting does not require an additional cooling system to cool the wind.

[0012] This technology can solve the above-mentioned problems. First of all, the cooling component, blowing component and ventilation component of this technology are all driven by the power component at the same time. Only one power source needs to be set up to drive the entire system. One power source can be used to blow away the cold air, adjust the air volume, dissipate the circumferential heat of the host, ventilate the chassis, ventilate and dustproof the chassis, and realize the precise blowing of the fan blades in each accessory area of ​​the host. At the same time, it can solve the noise problem of the heat dissipation mechanism during circular rotation. The entire system does not need to set up two or more power sources to realize multiple functions of heat dissipation of the host, reduce the waste of chassis energy, and can adjust the wind force according to the temperature of the host so as to control the temperature of the host at the optimal temperature of about 40 degrees.

[0013] The design can rotate the four fan blades through the blowing component to generate wind in the two heat sinks, and at the same time, the wind is mixed with the cold air to generate cold wind, which can be blown onto the computer host for heat dissipation. The rotation of the four fan blades can evenly dissipate the heat on the left and right sides and the top and bottom of the computer host, avoiding the phenomenon of heat accumulation due to high temperature on one side of the computer host and low temperature on the other side, thereby ensuring the performance of the computer host. At the same time, the adjustment part can drive the two heat sinks to rotate evenly in a circle on the outside of the computer host. With the rotation of the four fan blades, the outside of the computer host can be evenly cooled in a circle, and the computer host can be cooled in all directions to ensure the temperature of the computer host in all directions. The heat dissipation effect of the computer host can be further enhanced, and the heat accumulation of the computer host can be further avoided. The computer host can be effectively and evenly cooled by this method, and each accessory on the computer host, such as the CPU, motherboard, memory, power supply, hard disk, graphics card, network card and optical drive, can be continuously and evenly cooled. There is no need to continuously cool only one side of the CPU. The ventilation component can make the wind inside the chassis body float upward, and the inside of the chassis body can be ventilated, which can further enhance the heat dissipation effect of the computer host. At the same time, the chassis body can have a dust-proof effect during ventilation, and dust and particles can be prevented from entering the inside of the chassis body during ventilation.

At the same time, with the continuous entry of cold air into the inner sides of the two heat dissipation boxes and mixing with the wind force, cold air can be formed to blow on the computer host, which can dissipate heat for the computer host. Through the rotation of the four fan blades, the left and right sides and the top and bottom of the computer host can be evenly cooled, avoiding the phenomenon of heat accumulation due to high temperature on one side of the computer host and low temperature on the other side, thereby ensuring the performance of the computer host.

Through the connection and cooperation between the crank, connecting rod, connecting plate, two limit sliders and two limit slide grooves, the sponge can be moved left and right above the dust cover, and then the dust cover can be wiped and dusted, avoiding the accumulation of dust and particles above the dust cover to block the ventilation holes, thereby ensuring the ventilation effect of the chassis body.

[0023] By adopting the above technical scheme, through the cooperation between ten groups of buffer springs, ten groups of storage grooves, ten buffer plates and ten silencer cottons, the noise generated when the two heat sinks rotate can be silenced. When the heat sinks are in contact with the silencer cottons, the buffer springs will be in a compressed state, and then the buffer springs and silencer cottons can be used to silence the noise, so as to ensure the use environment of the chassis body and the computer host.

[0032] In summary, the present application includes at least one of the following beneficial technical effects: 1. Pour the coolant into the cooling coil to generate cold air on the outside of the cooling coil. Because the adjustment block is fixed at the bottom of the computer mainframe, the adjustment block will expand due to the high temperature when the temperature of the computer mainframe rises, and will shrink due to the temperature drop when the temperature of the computer mainframe drops. Therefore, the expansion and contraction of the adjustment block will change with the temperature change of the computer mainframe. When the adjustment block expands due to the temperature of the computer mainframe, 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 entire processing mechanism run. At the same time, when the adjustment 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 telescopic spring elastic force, the movable push plate and the two movable racks can be driven to move up and down in turn, thereby driving the two movable gears and the two threaded rods to rotate respectively, and then driving the two threaded blocks and the two adjustment plates to move left and right respectively, and the size of the air intake gap between the air intake hole can be adjusted; 2. When the temperature of the adjustment block rises, the air intake gap between the adjustment plate and the air intake hole will become larger. At the same time, when the temperature of the adjustment block drops, the air intake gap between the adjustment plate and the air intake hole will become smaller. The air intake 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 will quickly pass through the two through holes and the two air intake holes to enter the inner sides of the two heat dissipation boxes due to the large air intake 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 will slowly pass through the two through holes and the two air intake holes to enter the inner sides of the two heat dissipation boxes due to the small air intake gap, so as to slow down the subsequent heat dissipation effect of the computer host, so as to ensure the computer The computer host is heat-dissipated at the best temperature to avoid burning of the computer host due to over-high temperature, and to avoid performance degradation and startup difficulties caused by over-low temperature. When the temperature of the computer host is about 40 degrees in the normal range, the adjustment block will not change. At the same time, the adjustment block will shrink and separate from the motor switch due to the decrease in the temperature of the computer host, so that the motor can stop driving and the entire processing mechanism can stop running, avoiding more energy consumption caused by the processing mechanism, and also avoiding the performance degradation caused by the processing mechanism continuously cooling the computer host, so as to ensure the stability of the heat dissipation of the computer host; 3. When the motor starts, it will drive the driving shaft, the transmission gear, the two connecting gears, the two connecting shafts and the two movable blades to rotate in sequence to generate wind force, which can blow away the cold air on the outside of the cooling coil. As the wind passes through the multiple air holes in the cooling coil, it blows into the two air inlet holes in the turntable. Through the rotation of the two movable blades, the cold air on the left and right sides of the cooling coil can be quickly dispersed. Before the cold air enters the two air inlet holes, the two absorbent cotton plates will absorb and filter the moisture in the cold air to remove the moisture in the cold air to prevent the moisture in the cold air from entering the chassis body and affecting the computer host. The filtered cold air will float to the two through holes and the two heat sinks through the two air inlet holes respectively. At the same time, the floating speed of the cold air entering the two heat sinks can be controlled by moving the adjustment plate left and right. When the driving shaft rotates, it will drive the turntable, the two absorbent cotton plates, the two heat sinks, the two cylindrical gears, the two movable rods, and the inner bevel gear to rotate in sequence, and then drive the two movable rods, the two first bevel gears, the two second bevel gears, the two The first universal joint, two driving wheels, two transmission belts, two driven wheels, two second universal joints, four telescopic rods and four fan blade universal joints rotate, and then respectively drive the four fan blades to rotate to generate wind force. At the same time, cold air continuously enters the inner side of the two heat dissipation boxes and mixes with the wind force to form cold wind. Through the rotation of the four fan blades, the cold wind can be blown onto the computer host through multiple heat dissipation holes on the inner side of the two heat dissipation boxes, so that the computer host can be cooled. Through the rotation of the four fan blades, the left and right sides and the top and bottom of the computer host can be evenly cooled, avoiding the phenomenon of heat accumulation due to high temperature on one side of the computer host and low temperature on the other side, thereby ensuring the performance of the computer host. At the same time, when the two heat dissipation boxes rotate, the rotation of the four fan blades can make the outer side of the computer host evenly cool in the circumference, so that the computer host can be cooled in all directions, ensuring that the temperature of the computer host is consistent in all directions, enhancing the cooling effect of the computer host, and further avoiding the phenomenon of heat accumulation in the computer host. 4. When the four fan blade universal joints rotate at the same time, the four eccentric gears will also be driven to rotate respectively, because the four eccentric gears are respectively meshed with the four limit gears. Therefore, when the four limit gears rotate, through the connection and cooperation between the two first universal joints, the two second universal joints, the four telescopic rods, the four fan blade universal joints, the four eccentric gears, the four limit gears, the four limit blocks, the four fixed blocks and the four limit slots, the four fan blades can have the effect of swinging up and down when rotating, which can ensure the effect of the four fan blades on the computer host to blow air and cool down, so as to ensure that each position of the computer host can be blown and cooled, and the four fan blades can strengthen the effect of the computer host on the computer host. The cooling and heat dissipation effect of the computer host is improved to avoid different temperatures at each position of the computer host, and to avoid the phenomenon of heat accumulation in the computer host as much as possible, so as to achieve the effect of uniform range of the computer host. At the same time, when the two heat dissipation boxes rotate in a circle inside the chassis body, the noise generated by the circular rotation of the two heat dissipation boxes can be silenced through the cooperation between ten groups of buffer springs, ten groups of storage slots, ten buffer plates, dampers and ten silencer cottons. When the heat dissipation boxes are fitted with the silencer cotton, the buffer springs are in a compressed state, and then the noise can be absorbed and silenced by the buffer springs and silencer cotton to ensure the use environment of the chassis body and the computer host; 5. Because the inner bevel gear is meshed with the outer bevel gear, when the inner bevel gear rotates, it will drive the outer bevel gear, the fan blade rod and the reverse blade to rotate in turn to generate suction, so that the wind inside the chassis body can be sucked into the inner side of the fixed box through the air inlet pipe, and the wind can float out through the multiple ventilation holes on the inner side of the dust cover, so that the wind inside the chassis body can float upward, and then the inner side of the chassis body can be ventilated, which can further enhance the heat dissipation effect of the computer host. The dust cover can make the fixed box dustproof during ventilation, so as to prevent dust and particles from entering the fixed box and the inner side of the chassis body during ventilation, and prevent the computer host from being affected by dust and stains.

A host switch is fixedly connected to the top of the wiring board 3, which can turn the computer host 2 on or off. The computer host 2 can be hidden and protected by the chassis body 1 to prevent the computer host 2 from being damaged by the impact of external forces, and at the same time, the computer host 2 can be made dust-proof. By setting a soft plastic plate 32, the movable push plate 30 and the motor switch 31 can be isolated and protected to prevent the motor switch 31 from being damaged by friction with the adjustment block 59 when rotating, and at the same time, it will not affect the adjustment block 59 driving the motor switch 31.

[0046] The implementation principle of a computer case with heat dissipation and dust prevention functions in the embodiment of the present application is as follows: (1) By opening the movable cover 22, the coolant can be poured into the inner side of the cooling coil 20 through the water inlet pipe 21, so that cold air can be generated on the outer side of the cooling coil 20. Because the adjustment block 59 is fixed to the bottom of the computer host 2, when the temperature of the computer host 2 rises, the adjustment block 59 will expand due to the high temperature. At the same time, when the temperature of the computer host 2 drops, the adjustment block 59 will contract due to the temperature drop. Therefore, the expansion and contraction of the adjustment block 59 will change with the temperature change of the computer host 2. (2) When the adjusting block 59 expands due to the temperature of the computer host 2, it will squeeze the soft plastic plate 32, the motor switch 31 and the movable push plate 30. First, when the motor switch 31 is squeezed, the motor 5 will be started to operate the entire processing mechanism. At the same time, when the adjusting block 59 expands or contracts due to the temperature, it will push the movable push plate 30 to move up and down. Through the elastic compression of the telescopic spring 61, the movable push plate 30 and the two movable racks 33 can be driven to move up and down in turn, which will respectively drive the two movable gears 34 and the two threaded rods 35 to rotate, and then respectively drive the two threaded blocks 36 and the two adjusting plates 37 to move left and right, so as to adjust the size of the air intake gap between the air intake hole and the air intake hole; (3) When the temperature of the adjustment block 59 increases, the air intake gap between the adjustment plate 37 and the air intake hole will become larger. At the same time, when the temperature of the adjustment block 59 decreases, the air intake gap between the adjustment plate 37 and the air intake hole will become smaller. The air intake gap can be adjusted according to the temperature change of the computer host 2. When the temperature of the computer host 2 is too high, the cold air can quickly pass through the two through holes and the two air intake holes due to the large air intake gap and enter the inner side of the two heat dissipation boxes 8 respectively, so as to enhance the subsequent heat dissipation effect of the computer host 2; (4) When the temperature of the computer host 2 drops, the cold air slowly passes through the two through holes and the two air inlet holes due to the small air inlet gap and enters the inner side of the two heat sinks 8 respectively, so as to slow down the subsequent heat dissipation effect of the computer host 2, so as to ensure that the computer host 2 performs heat dissipation processing at the best temperature state, thereby preventing the computer host 2 from being burned due to excessive temperature, and at the same time preventing the computer host 2 from being degraded and difficult to start due to excessively low temperature; (5) At the same time, when the temperature of the computer host 2 is about 40 degrees in the normal range, the adjustment block 59 will not change. At the same time, the adjustment block 59 will shrink and separate from the motor switch 31 due to the decrease in the temperature of the computer host 2, thereby stopping the driving of the motor 5 and stopping the operation of the entire processing mechanism, thereby avoiding more energy consumption caused by the processing mechanism. At the same time, it can also avoid the performance degradation caused by the processing mechanism continuously dissipating heat from the computer host 2, thereby ensuring the stability of the heat dissipation of the computer host 2; (6) When the motor 5 is started, it will drive the drive shaft 6 and the transmission gear 25 to rotate in turn, and then respectively drive the two connecting gears 26, the two connecting shafts 27 and the two movable blades 28 to rotate. When the movable blades 28 rotate, wind force will be generated, and then the cold air outside the cooling coil 20 can be blown away. As the wind force passes through the multiple air holes in the cooling coil 20 and blows into the two air inlet holes in the turntable 7, the cold air on the left and right sides of the cooling coil 20 can be quickly blown away by the rotation of the two movable blades 28. Before the cold air enters the two air inlet holes, the two absorbent cotton plates 29 will absorb and filter the moisture in the cold air to remove the moisture in the cold air, so as to prevent the moisture in the cold air from entering the chassis body 1 and affecting the computer host 2. The filtered cold air will float to the two through holes and the two heat sinks 8 through the two air inlets respectively. At the same time, the floating speed of the cold air entering the two heat sinks 8 can be controlled by moving the adjustment plate 37 left and right. (7) When the driving shaft 6 rotates, it will drive the turntable 7, the two absorbent 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 sequence. When the two cylindrical gears 10 rotate, they will respectively drive the two movable rods 11 and the two first bevel gears 12 to rotate. When the two first bevel gears 12 rotate, they will respectively drive the two second bevel gears 13, the two first universal joints 14 and the two driving wheels 15 to rotate. When the two driving wheels 15 rotate, they will respectively 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. The two first universal joints 14 and the two second universal joints 18 rotate. When the four telescopic rods 62, the four fan blade universal joints 63 and the four fan blades 19 are respectively driven to rotate to generate wind force, and at the same time, the cold air continuously enters the inner side of the two heat dissipation boxes 8 and mixes with the wind force to form cold wind. Through the rotation of the four fan blades 19, the cold wind can be blown onto the computer host 2 through the multiple heat dissipation holes on the inner side of the two heat dissipation boxes 8, and then the computer host 2 can be cooled. Through the rotation of the four fan blades 19, the left and right sides and the top and bottom of the computer host 2 can be evenly cooled, avoiding the phenomenon of heat accumulation due to high temperature on one side of the computer host 2 and low temperature on the other side, thereby ensuring the performance of the computer host 2. (8) When the four fan blade universal joints 63 rotate at the same time, the four eccentric gears (64) will also be driven to rotate respectively. Because the four eccentric gears (64) are respectively meshed with the four limit gears 65, 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 telescopic rods 62, the four fan blade universal 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 swing effect when rotating, which can ensure that the four fan blades 19 have an effect of blowing air and cooling the computer host 2, so as to ensure that each position of the computer host 2 can be cooled by blowing air, and the effect of cooling and dissipating the heat of the computer host 2 can be enhanced, so as to avoid that the temperature of each position of the computer host 2 is different, and the phenomenon of heat accumulation in the computer host 2 is avoided as much as possible, so as to achieve the effect of uniform range of the computer host 2; (9) When the two heat sinks 8 rotate at the same time, the four fan blades 19 rotate, so that the outer side of the computer host 2 can be evenly cooled in a circumferential manner, and the computer host 2 can be cooled in all directions to ensure that the temperature of the computer host 2 is consistent in all directions, thereby enhancing the heat dissipation effect of the computer host 2 and further avoiding the phenomenon of heat accumulation in the computer host 2; (10) When the two heat sinks 8 rotate in a circle inside the chassis body 1, the noise generated by the rotation of the two heat sinks 8 can be silenced by the cooperation between the ten groups of buffer springs 53, the ten groups of storage grooves, the ten buffer plates 54, the dampers and the ten silencer cottons 55. When the heat sinks 8 fit the silencer cottons 55, the buffer springs 53 are in a compressed state, and then the buffer springs 53 and the silencer cottons 55 can absorb and silence the noise, so as to ensure the use environment of the chassis body 1 and the computer host 2; (11) Because the inner bevel gear 38 is meshed with the outer bevel gear 39, when the inner bevel gear 38 rotates, it will drive the outer bevel gear 39, the fan blade rod 40 and the reverse blade 41 to rotate in sequence. When the reverse blade 41 rotates, suction will be generated, and the wind force inside the chassis body 1 can be sucked into the inner side of the fixed box 42 through the air inlet pipe 52, and then the wind force can be blown out through the multiple ventilation holes inside the dust cover 43, so that the wind force inside the chassis body 1 can be blown upward, and the inner side of the chassis body 1 can be ventilated, which can further enhance the heat dissipation effect of the computer host 2; (12) The dust cover 43 can make the fixed box 42 dustproof during ventilation, so as to prevent dust and particles from entering the fixed box 42 and the inner side of the chassis body 1 during ventilation, thereby ensuring the hygiene of the computer host 2 and preventing the computer host 2 from being affected by dust and stains. At the same time, when the fan blade rod 40 rotates, it 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, and the connecting rod 49 is hinged to the connecting plate 50, and the connecting plate 50 is limited to the dust cover 4 by two limit sliders 58 and two limit slide grooves. 3, so when the rotating rod 47 rotates, the sponge 51 can be moved left and right above the dust cover 43 through the connection and cooperation between the crank 48, the connecting rod 49, the connecting plate 50, the two limit sliders 58 and the two limit slide grooves, so that the dust cover 43 can be brushed and dusted to avoid the accumulation of dust and particles on the dust cover 43 to block the ventilation holes, thereby ensuring the ventilation effect of the chassis body 1 and achieving the purpose of ventilation and dust prevention of the chassis body 1. At the same time, the sponge 51 can be used to brush the dust cover 43 to avoid the sponge 51 from generating noise on the dust cover 43.

[0047] Compared with the prior art, the cooling assembly, the blowing assembly and the ventilation assembly in the technology are all driven by the power assembly at the same time. Therefore, the blowing of the cold air of the cooling coil 20, the circumferential heat dissipation of the computer host 2, the rotation of the four fan blades 19, the up and down swinging of the four fan blades 19, the ventilation and heat dissipation inside the chassis body 1, and the wiping and anti-blocking of the dust cover 43 are all driven by a power source of the motor 5. The entire system does not need to be driven by other additional power sources, and does not need to be set up with two or more power sources to realize multiple functions when dissipating the heat of the computer host 2, thereby reducing energy waste, realizing the computer case to uniformly dissipate the heat of the computer host 2 in all directions, avoiding the phenomenon that the temperature of one side of the computer host 2 is high and the temperature of the other side is low, preventing the computer host 2 from accumulating heat, and avoiding the temperature of each component on the computer host 2 being different, thereby ensuring the heat dissipation efficiency of the computer host 2, improving the performance of the computer host 2, ensuring the heat dissipation effect of the computer host 2, reducing the probability of repair and manufacturing of the computer host 2, and enhancing the protection effect of the computer case on the computer host 2.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
