[0002] In today's digital age, computers have become indispensable devices for people's work, life, and study. However, the internal circuitry of computers is extremely complex and sophisticated, facing numerous potential threats during operation, thus creating an urgent need for computer circuit protection devices.

[0003] A computer protection device, patent publication number CN212256207U, includes a protective case and a door. The door is hinged to the surface of the protective case. Saddle trays are installed on the bottom of both sides of the inner cavity of the protective case. An L-shaped bracket is installed at the output end of each saddle tray.

Heat dissipation windows are opened on the surface of the heat sink, and dustproof mesh plates are installed on the surface of the heat dissipation windows. However, even with the addition of a protective case and heat dissipation windows, the above-mentioned device still causes a certain degree of heat insulation inside the computer case, affecting the heat dissipation effect inside the computer case, impacting the normal operation of the control circuit group, and reducing the service life of the control circuit group. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a computer circuit protection device that solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a computer circuit protection device, comprising a protective box, a door hinged to the front of the protective box, a computer host chassis placed on the bottom of the inner wall of the protective box, a baffle attached to the side wall of the computer host chassis, the baffle being bolted to the computer host chassis, a control circuit assembly fixed to the inner wall of the computer host chassis, wires fixed to the front of the control circuit assembly, the wires being plugged into the front and top of the control circuit assembly, a cooling fan fixed to the front of the control circuit assembly, a separating device for easily isolating the control circuit assembly from the wires on the front of the control circuit assembly, a protective device for easily protecting the wires below the separating device, and a collection device for easily adsorbing dust from the surface of the control circuit assembly below the separating device. The separating device includes a sliding rod, a connecting block, a fixed rod, a swing rod, a moisture-proof ball, a buffer spring, a sliding block, a separating rod, and a connecting rod. The sliding rod passes through one of the fan blades of the radiator fan and is rotatably connected at the point of penetration. The rotation of the radiator fan drives the sliding rod to rotate.

[0006] According to the above technical solution, the sliding rod is slidably connected to the front of the control circuit group, the connecting block is fixedly connected to the end of the sliding rod away from the control circuit group, and the fixed rod is fixedly connected to the end of the connecting block away from the sliding rod. The rotation of the sliding rod drives the fixed rod to rotate through the connecting block.

[0007] According to the above technical solution, the fixed rod passes through the upper end of the swing rod and is rotatably connected at the point of penetration. The end of the swing rod away from the fixed rod is fixedly connected to the end of the swing rod away from the fixed rod. The rotation of the fixed rod causes the moisture-proof ball to swing.

[0008] According to the above technical solution, one end of the buffer spring is fixedly connected to the bottom surface of the connecting block, the other end of the buffer spring is fixedly connected to the upper surface of the sliding block, and the separator bar is slidably connected to the side wall of the computer host chassis.

[0009] According to the above technical solution, a connecting plate is fixed to one end of the separator bar away from the side wall of the computer host chassis, and the connecting rod is fixedly connected to the side of the connecting plate near the separator bar. The bottom surface of the sliding block is slidably connected to the upper surface of the connecting rod, and the sliding block moves up and down, causing the connecting rod to move up and down.

[0010] According to the above technical solution, the protective device includes a roller, an extrusion block, a pressure plate, and a magnet. One end of the roller passes through the connecting plate and is rotatably connected at the point of penetration. The end of the connecting rod away from the connecting plate is fixed.

[0011] According to the above technical solution, the other end of the roller passes through the fixed plate and is rotatably connected at the point of penetration. The pressing block is fixedly connected to the end of the fixed plate and the connecting plate near the connecting rod. The pressure plate is slidably connected to the front of the control circuit assembly. The magnet is fixedly connected to the upper surface of the pressure plate. The magnets repel each other and push the pressure plates away from each other.

[0012] According to the above technical solution, the collecting device includes a friction block, a fixed column, a hinge plate, and a collecting box. The friction block is fixedly connected to the side wall of the sliding block away from the control circuit group. The bottom end of the friction block is slidably connected to the side wall of the connecting rod away from the control circuit group. The friction between the friction block and the connecting rod generates static electricity.

[0013] According to the above technical solution, the fixing column is fixedly connected to the side of the fixing plate away from the connecting rod. The fixing column passes through the upper end of the hinge plate and is rotatably connected at the penetration point. The collection box is fixedly connected to the end of the hinge plate away from the fixing column. The collection box collects the dust that falls from the surface of the connecting rod.

[0014] This invention provides a computer circuit protection device. It has the following beneficial effects: 1. This invention includes a separating device. When the computer is working, the rotation of the cooling fan drives the sliding rod to rotate, which, in conjunction with the connecting block, fixing rod, and swing rod, causes the desiccant ball to swing left and right. This creates turbulence on the upper and front surfaces of the control circuit assembly, further increasing the airflow speed and improving the heat dissipation efficiency of the control circuit assembly. Simultaneously, it prevents moisture from entering the computer case, thus avoiding malfunctions of the control circuit assembly due to humidity or excessive temperature. This solves the problem of heat dissipation being more difficult inside the host unit within the protective case and adds a moisture-proof measure. While the desiccant ball swings, the buffer spring, sliding block, and connecting rod drive the separating rod to move up and down, separating the wires from the control circuit assembly. This prevents the wires and control circuit assembly from being too tightly fitted, which could cause a short circuit. It also increases the contact area between the wires, control circuit assembly, and air, further improving the heat dissipation efficiency of the control circuit assembly and wires, and solving the problem of short circuits caused by excessive tightness between the wires and control circuit assembly.

[0015] 2. This invention includes a protective device. When separating the wires from the control circuit assembly, a separator bar is used to straighten the wires on the surface of the rollers, thus preventing the wires from tangling when they are too loose. Furthermore, the aging of the wire sheaths after long-term use can lead to leakage, circuit errors, or short circuits when the wires become tangled, thus solving the problem of wires easily tangling. Simultaneously, the pressing block is raised, pushing the pressure plates closer together to shield the wires from above. The rollers and separator bar also press the upper end of the wires downwards, preventing the upper end from rising and contacting the cooling fan, thus preventing it from winding into the cooling fan and causing a short circuit. This solves the problem of long wires easily winding into the cooling fan.

[0016] 3. This invention includes a collection device. While the power cord is being moved, a sliding block repeatedly slides on the upper surface of the connecting rod, causing a friction block to rub against the surface of the connecting rod. This generates static electricity between the friction block and the connecting rod, attracting the dust stirred up when the power cord is moved. This prevents the dust from falling back onto the surface of the control circuit assembly, causing accumulation and affecting the contact between the control circuit assembly and the air, thus reducing the heat dissipation efficiency of the control circuit assembly. This solves the problem of dust accumulation on the surface of the control circuit assembly, which affects heat dissipation. After the computer stops working, the collection box, in conjunction with the fixing column and hinge plate, keeps the collection box below the hinge plate, collecting the dust that falls after the hinge plate loses its suction force. This prevents maintenance personnel from flipping the hinge plate during computer maintenance, causing dust on its surface to fall into the control circuit assembly, thus increasing the workload for maintenance. This solves the problem of difficult automatic dust collection inside the computer case, which increases the workload for maintenance personnel. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 One embodiment of the present invention is as follows: a computer circuit protection device includes a protective box 1, a door 2 hinged to the front of the protective box 1, a computer host chassis 3 placed on the bottom surface of the inner wall of the protective box 1, a baffle 4 attached to the side wall of the computer host chassis 3, the baffle 4 being bolted to the computer host chassis 3, a control circuit assembly 5 fixed to the inner wall of the computer host chassis 3, a wire 6 fixed to the front of the control circuit assembly 5, the wire 6 being plugged into the front and top of the control circuit assembly 5, a cooling fan 7 fixed to the front of the control circuit assembly 5, and a separation device for facilitating isolation between the control circuit assembly 5 and the wire 6 provided on the front of the control circuit assembly 5.

[0021] The separating device includes a sliding rod 81, a connecting block 82, a fixed rod 83, a swing rod 84, a moisture-proof ball 85, a buffer spring 86, a sliding block 87, a separating rod 88, and a connecting rod 89. The sliding rod 81 passes through one of the fan blades of the radiator fan 7 and is rotatably connected at the point of penetration. The sliding rod 81 is slidably connected to the front of the control circuit assembly 5. The rotation of the radiator fan 7 drives the sliding rod 81 to rotate around the central axis of the radiator fan 7. The connecting block 82 is fixedly connected to the end of the sliding rod 81 away from the control circuit assembly 5. When the sliding rod 81 rotates around the central axis of the radiator fan 7, it drives the connecting block 82 to move left and right. The fixed rod 83 is fixedly connected to the end of the connecting block 82 away from the sliding rod 81. The fixed rod 83 passes through the upper part of the swing rod 84. The end of the connecting block 82 is rotated at the through-hole. When the connecting block 82 moves left and right, it drives the fixed rod 83 to move left and right as well. The swing rod 84 is located at the end away from the fixed rod 83. The swing rod 84 is made of a highly elastic soft material. The moisture-proof ball 85 is fixedly connected to the end of the swing rod 84 away from the fixed rod 83. The moisture-proof ball 85 consists of an absorbent layer, a drying layer, and an iron ball core. When the fixed rod 83 moves left and right, it drives the swing rod 84 and the moisture-proof ball 85 to move together. Due to inertia, the moisture-proof ball 85 moves one step slower than the fixed rod 83, causing the moisture-proof ball 85 to move relative to the fixed rod 83. Since the swing rod 84 has high elasticity, when the moisture-proof ball 85 moves relative to the fixed rod 83, it drives the swing rod 84 to swing. The swing rod 84 is stretched, and the elastic force of the stretched swing rod 84 pulls the moisture-proof ball 85 to swing more widely, disturbing the air around the control circuit group 5 and accelerating the airflow. One end of the buffer spring 86 is fixedly connected to the bottom surface of the connecting block 82, and the other end of the buffer spring 86 is fixedly connected to the upper surface of the sliding block 87. When the sliding rod 81 drives the connecting block 82 to move downward, the connecting block 82 compresses the buffer spring 86. After being subjected to pressure, the buffer spring 86 releases its elastic force, pushing the sliding block 87 to move downward. The separator rod 88 is slidably connected to the side wall of the computer host chassis 3. The end of the separator rod 88 away from the side wall of the computer host chassis 3 is fixed with a connecting plate. The connecting rod 89 is fixedly connected to the connecting plate. On the side of the plate near the separator 88, the bottom surface of the sliding block 87 is slidably connected to the upper surface of the connecting rod 89. The sliding block 87 drives the connecting rod 89 to move downwards, and the connecting rod 89 drives the separator 88 to slide downwards. The separator 88 repeatedly moves up and down to separate the wire 6, preventing the wire 6 from being too tightly attached to the control circuit assembly 5. When the computer is working, this separation device, through the rotation of the cooling fan 7, drives the sliding rod 81 to rotate. In conjunction with the connecting block 82, the fixed rod 83, and the swing rod 84, it drives the desiccant ball 85 to swing left and right, creating turbulence on the upper and front surfaces of the control circuit assembly 5, further increasing the airflow speed and improving the heat dissipation efficiency of the control circuit assembly 5, while simultaneously preventing moisture from entering the computer host chassis 3.This prevents the control circuit group 5 from malfunctioning due to humid or high-temperature environments, and solves the problem of even greater difficulty in heat dissipation inside the main unit within the protective box 1; Furthermore, moisture-proof measures have been added; while the moisture-proof ball 85 is swinging, the buffer spring 86, sliding block 87 and connecting rod 89 drive the separator 88 to move up and down, separating the wire 6 from the control circuit group 5, thereby preventing the wire 6 from being too tightly attached to the control circuit group 5 and causing a short circuit. At the same time, it facilitates increasing the contact area between the wire 6, the control circuit group 5 and the air, further improving the heat dissipation efficiency of the control circuit group 5 and the wire 6, and solving the problem of short circuits caused by the wire 6 being too tightly attached to the control circuit group 5.

[0022] In this embodiment, during operation: the rotation of the cooling fan 7 drives the sliding rod 81 to rotate around the central axis of the cooling fan 7. As the sliding rod 81 rotates around the central axis of the cooling fan 7, it causes the connecting block 82 to move left and right. This left and right movement of the connecting block 82 also causes the fixed rod 83 to move left and right. The left and right movement of the fixed rod 83 causes the swing rod 84 and the desiccant ball 85 to move together. Due to inertia, the desiccant ball 85 moves slightly slower than the fixed rod 83, resulting in the desiccant ball 85 moving relative to the fixed rod 83. Since the swing rod 84 has high elasticity, its movement relative to the fixed rod 83 causes it to swing, stretching the swing rod 84. This stretching force pulls the desiccant ball 85 to swing more dramatically, affecting the control circuit. The air around group 5 is turbulent, increasing the airflow speed. When the sliding rod 81 moves the connecting block 82 downward, the connecting block 82 compresses the buffer spring 86. After being compressed, the buffer spring 86 releases its elasticity, pushing the sliding block 87 downward. The sliding block 87 moves the connecting rod 89 downward, and the connecting rod 89 moves the separator bar 88 downward. When the sliding rod 81 moves the connecting block 82 upward, the connecting block 82 stretches the buffer spring 86. After being stretched, the buffer spring 86 pulls the sliding block 87 upward to restore its deformation. The sliding block 87 moves the connecting rod 89 upward, and the connecting rod 89 moves the separator bar 88 upward. The separator bar 88 moves up and down repeatedly to separate the wire 6, preventing the wire 6 from being too tightly attached to the control circuit group 5.

[0023] Please see Figures 1-7In another embodiment of the present invention, based on the above embodiments, a protective device for facilitating the protection of the wire 6 is provided below the separating device. The protective device includes a roller 91, a pressing block 92, a pressure plate 93, and a magnet 94. One end of the roller 91 passes through the connecting plate and is rotatably connected at the penetration point. The surface of the roller 91 is covered with rubber. The roller 91 and the separating rod 88 clamp the wire 6 in the middle, and the surfaces of the roller 91 and the separating rod 88 are in contact with the wire 6. A fixing plate is fixed to the end of the connecting rod 89 away from the connecting plate. The other end of the roller 91 passes through the fixing plate and is rotatably connected at the penetration point. When the sliding block 87 drives the connecting rod 89 to move upward, the connecting rod 89, in conjunction with the connecting plate and the fixing plate, drives the roller 91 to move upward. The separating rod 88 slides up and down in contact with the surface of the wire 6, while the roller 91 rolls in contact with the surface of the wire 6. The pressing block 92 is fixedly connected to the fixing plate and the end of the connecting plate near the connecting rod 89. When the connecting rod 89 moves upward... The device uses a fixed plate and a connecting plate to move two sets of pressing blocks 92 upwards. The pressure plate 93 is slidably connected to the front of the control circuit group 5. When the pressing block 92 moves upwards to the pressure plate 93, it pushes the pressure plate 93 to slide towards the center of the control circuit group 5. The two sets of pressure plates 93 move closer to each other and block the wire 6 above. The magnet 94 is fixedly connected to the upper surface of the pressure plate 93. When the pressure plate 93 is no longer pushed by the pressing block 92, the repulsive force between the two sets of magnets 94 causes it to slide away from the center of the control circuit group 5, so that the two sets of pressure plates 93 move away from each other. When the protective device separates the wire 6 from the control circuit group 5, it works with the separator 88 to straighten the roller 91 on the surface of the wire 6, thereby preventing the wire 6 from getting tangled when it is too loose. In addition, the outer shell of the wire 6 has aged over long-term use. When it gets tangled, it may cause leakage, circuit errors or short circuits. This device solves the problem that the wire 6 is prone to getting tangled. While straightening the wire 6, the pressing block 92 is driven to rise and push the pressure plate 93 closer together to block the wire 6 from above. In conjunction with the roller 91 and the separator 88, the upper end of the wire 6 is pressed down to prevent the upper end of the wire 6 from being pushed up and contacting the cooling fan 7, or getting wrapped around the cooling fan 7, thus causing a circuit breaker. This solves the problem that the wire 6 is easy to get wrapped around the cooling fan 7 when it is too long.

[0024] Below the separator is a collection device for facilitating the adsorption of dust from the surface of the control circuit assembly 5. The collection device includes a friction block 101, a fixed post 102, a hinge plate 103, and a collection box 104. The friction block 101 is fixedly connected to the side wall of the sliding block 87 away from the control circuit assembly 5. The bottom end of the friction block 101 is slidably connected to the side wall of the connecting rod 89 away from the control circuit assembly 5. The friction block 101 is made of glass, and a layer of silk is attached to the front of the connecting rod 89. When the connecting block 82 moves left and right, a spring causes the sliding block 87 to also adhere to the upper surface of the connecting rod 89. When the sliding block 87 slides left and right, it drives the friction block 101 to slide left and right as well. The friction block 101 slides left and right on the front of the connecting rod 89, causing the connecting rod 89 to generate static electricity, which attracts dust from the surface of the wires 6 and the control circuit group 5. The fixing post 102 is fixedly connected to the side of the fixing plate away from the connecting rod 89. The fixing post 102 passes through the upper end of the hinge plate 103 and is rotatably connected at the penetration point. The collection box 104 is fixedly connected to the end of the hinge plate 103 away from the fixing post 102. When the computer stops working, the cooling fan 7... Gradually coming to a stop, connecting block 82 no longer drives sliding block 87 to slide left and right, and friction block 101 no longer rubs against the front of connecting rod 89. After a period of time, the static electricity on connecting rod 89 dissipates, and the dust on the surface of connecting rod 89 falls into collection box 104. When the staff needs to flip and open the computer host case 3, collection box 104 remains perpendicular to the horizontal plane due to gravity. Collection box 104 drives hinge plate 103 to rotate relative to connecting rod 89 around fixed post 102, catching the dust on the surface of connecting rod 89, making it convenient for staff to access the computer. The cleaning process involves the collection device repeatedly sliding the sliding block 87 on the upper surface of the connecting rod 89 while the wire 6 is being moved. This causes the friction block 101 to rub against the surface of the connecting rod 89, generating static electricity between the friction block 101 and the connecting rod 89. This attracts the dust that is stirred up when the wire 6 is moved, preventing the dust from falling back onto the surface of the control circuit assembly 5 and accumulating, which would affect the contact between the control circuit assembly 5 and the air, thereby reducing the heat dissipation efficiency of the control circuit assembly 5. This solves the problem of dust accumulation on the surface of the control circuit assembly 5, which affects heat dissipation. After the computer stops working, the collection box 104, in conjunction with the fixing column 102 and the hinge plate 103, keeps the collection box 104 below the hinge plate 103. This collects the dust that falls after the hinge plate 103 loses its suction force, preventing the staff from flipping the hinge plate 103 during computer maintenance and causing dust on the upper surface of the hinge plate 103 to fall into the control circuit group 5, thus increasing the workload of maintenance. This solves the problem of the difficulty in automatically collecting dust inside the chassis, which increases the workload of the staff.

[0025] In this embodiment, when the sliding block 87 moves the connecting rod 89 upward, the connecting rod 89, in conjunction with the connecting plate and the fixing plate, moves the roller 91 upward. Since the wire 6 is sandwiched between the roller 91 and the separator rod 88, and is tightly fitted, and the surface of the roller 91 is covered with rubber, resulting in high friction, when the separator rod 88 and the roller 91 move up and down, the separator rod 88 slides up and down against the surface of the wire 6, while the roller 91 rolls against the surface of the wire 6, straightening the wire 6 and preventing it from becoming tangled and causing short circuits or other accidents. When the connecting rod 89 moves upward, the fixing plate and the connecting plate drive the two sets of pressing blocks 9... 2. When the pressing block 92 moves upward to the pressure plate 93, the inclined surface of the pressing block 92 slides against the side of the pressure plate 93. The pressing block 92 pushes the pressure plate 93 to slide towards the center of the control circuit group 5. The two pressure plates 93 move closer to each other and block the wire 6 above, preventing the wire 6 from moving upward and getting into the cooling fan 7. When the connecting rod 89 moves downward, the fixing plate and the connecting plate drive the two pressing blocks 92 to move downward. At this time, the pressure plate 93 is no longer pushed by the pressing block 92. At the same time, the repulsive force between the two magnets 94 drives them to slide away from the center of the control circuit group 5, so that the two pressure plates 93 move away from each other.

[0026] When the cooling fan 7 rotates, the connecting block 82 rotates around the central axis of the cooling fan 7. Therefore, while the connecting block 82 moves up and down, it also moves left and right. When the connecting block 82 moves left and right, the spring drives the sliding block 87 to slide left and right against the upper surface of the connecting rod 89. When the sliding block 87 slides left and right, it drives the friction block 101 to slide left and right as well. The friction block 101 slides left and right on the front side of the connecting rod 89 and rubs against it, causing the connecting rod 89 to generate static electricity. This static electricity attracts dust from the surface of the wires 6 and the control circuit assembly 5. When the computer stops working, the dust dissipates. As the fan 7 gradually stops, the connecting block 82 no longer drives the sliding block 87 to slide left and right, and the friction block 101 no longer rubs against the front of the connecting rod 89. After a period of time, the static electricity on the connecting rod 89 dissipates, and the dust on the surface of the connecting rod 89 falls into the collection box 104. When the staff needs to flip the computer host case 3 over and open it, the collection box 104 remains perpendicular to the horizontal plane due to gravity. The collection box 104 drives the hinge plate 103 to rotate relative to the connecting rod 89 around the fixed column 102, catching the dust on the surface of the connecting rod 89, making it convenient for the staff to clean.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
