Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning devices, and specifically relates to an automatic cleaning mechanism for a GPU group. Background Technique

[0002] The full name of GPU is the display interface card, also known as the display adapter. It is one of the most basic configurations and important accessories of a computer. As an important part of the computer host, the GPU is a device for converting digital and analog signals in the computer, and undertakes the task of outputting and displaying graphics. The GPU is connected to the computer motherboard, which converts the digital signal of the computer into an analog signal for the display to show. At the same time, the GPU also has image processing capabilities, which can assist the CPU to work and improve the overall operation speed. When dust adheres to the surface of the GPU, a cleaning device is often needed for cleaning.

[0003] A patent with the publication number CN217797569U discloses an automatic cleaning mechanism for a GPU group. By inserting the GPU into the slot in the concave support plate and combining the resilience of the spring return rod, it is beneficial to quickly clamp the GPU through the cooperation of the first clamping plate and the second clamping plate. Then, the lifting component drives the GPU to move up and pass through between the two dust suction shaft tubes. At this time, when the cleaning brush rotates, it will automatically sweep and clean the front and rear end faces of the GPU, so as to achieve the effect of automatically cleaning the GPU. The above-mentioned existing technology still has some problems in the application process. Usually, the GPU uses its own cooling fan to blow air to cool the operating motherboard. When the cooling fan runs, it will draw external dust into the GPU, which may lead to situations such as short circuit and damage of the GPU. Moreover, blowing air for heat dissipation is likely to blow dust into the GPU, resulting in the need to shut down the host when cleaning the GPU and separately disassemble the GPU for cleaning, which is very cumbersome and affects the use of the computer.

Detailed implementation manners

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners. Embodiment 1

[0021] As Figures 1 to 9 shown, a GPU group automatic cleaning mechanism according to an embodiment of the present invention, the GPU includes a GPU main board 1, a power-on plug 2 is arranged at the front end of the GPU main board 1, a chassis mounting block 3 is fixedly connected to one side of the GPU main board 1, a power connection slot 18 is opened on one end face of the chassis mounting block 3, a heat dissipation cover 4 is installed on the upper end face of the GPU main board 1, a heat dissipation port 5 is opened on the upper end face of the heat dissipation cover 4, and the cleaning device is used in cooperation with the GPU and includes a heat dissipation and dust cleaning component arranged in the inner cavity of the heat dissipation port 5; And the heat dissipation and dust cleaning component includes a cooling fan 22 installed in the inner cavity of the heat dissipation port 5; A dust-proof net plate 21 is installed on the upper wall of the inner cavity of the heat dissipation port 5, and the dust-proof net plate 21 is provided with a double layer, and a dust collection cavity is arranged between the two dust-proof net plates 21 for guiding the collection of dust; An L-shaped cleaning rod 23 is installed at the upper end of the heat dissipation fan 22 , and fluff brushes are evenly arranged on the outside of the L-shaped cleaning rod 23 for brushing and cleaning the fluff, spider webs and dust on the surface of the dustproof mesh plate 21 .

[0022] Specifically, in the prior art, the cooling fan of the GPU is usually used to blow air to cool the running motherboard. When the cooling fan is running, it will draw external air into the GPU, and then carry a small amount of dust into the GPU motherboard. When cleaning the GPU, the computer needs to be turned off, and then the operator uses a small vacuum cleaner to clean the dust from the dustproof plate at the GPU cooling fan. It is difficult to remove the dust that falls into the GPU, and some fluff sticks to the dustproof mesh plate, which also needs to be cleaned by the operator. Not only is the labor intensity high, but the GPU installation is also easily loosened during cleaning, resulting in contact short circuit problems. The present invention is installed with the computer case by using the case mounting block 3, and is installed by plugging with the computer mainboard by using the power plug 2. Then, when the computer is running, the GPU mainboard 1 starts the cooling fan 22, and the cooling fan 22 drives the L-shaped cleaning rod 23 to rotate. Since brushes are evenly arranged on the outside of the L-shaped cleaning rod 23, and the L-shaped cleaning rod 23 rotates between the two dustproof mesh plates 21, the brush is used to brush and clean the surface of the dustproof mesh plate 21 during the rotation of the L-shaped cleaning rod 23, so that the fluff, spider webs and dust on the surface of the dustproof mesh plate 21 are brushed and cleaned, and the fluff, spider webs and dust are prevented from accumulating on the surface of the dustproof mesh plate 21, thereby affecting the efficiency of the cooling fan 22 in extracting external air, and affecting the cooling and heat dissipation effect of the GPU mainboard 1, thereby solving the above-mentioned problem.

[0023] like Figures 2 to 4 As shown, a dust cleaning and conveying assembly 6 is installed on the upper end surface of the GPU mainboard 1, and the dust cleaning and conveying assembly 6 includes a support frame 61 installed on the upper end surface of the GPU mainboard 1; A plurality of cleaning blades 66 are rotatably connected between the support frames 61; Brushes 20 are provided at both ends of the cleaning blade 66 , and the brushes 20 are made of RP thermoplastic rubber material and are used to clean dust on the surface of the GPU mainboard 1 .

[0024] Specifically, when cleaning the GPU motherboard 1, the cleaning blade 66 is driven to rotate while the GPU motherboard 1 is running. Since brushes 20 are provided at both ends of the cleaning blade 66, and the brush 20 is made of RP thermoplastic rubber material, dust can be cleaned from the surface of the GPU motherboard 1. The brush 20 is soft and resistant to high temperatures. Therefore, when cleaning dust from the surface of the GPU motherboard 1, the brush 20 can be prevented from causing scratches on the surface of the GPU motherboard 1, thereby affecting the operation of the GPU and reducing the service life of the GPU.

[0025] likeFigures 2 to 4 As shown in the figure, a transmission groove 62 is provided inside one end of the support frame 61. A rotating shaft 63 is rotatably connected to the inner cavity of the transmission groove 62. A plurality of transmission bevel gears 64 are fixedly connected to the outside of the rotating shaft 63. And the plurality of transmission bevel gears 64 are meshed with a driven bevel gear 65. And one end of the plurality of driven bevel gears 65 penetrates through the support frame 61 and is fixedly connected to the cleaning blade 66.

[0026] As Figures 2 to 4 shown, the transmission bevel gear 64 is meshed with a first bevel gear 17. One end of the first bevel gear 17 is fixedly connected with a T-shaped rotating block 15. And the T-shaped rotating block 15 is rotatably connected to the support frame 61. A cross slot 16 is provided at the upper end of the T-shaped rotating block 15.

[0027] Specifically, when the radiator fan 22 operates, the driven pulley 24 is driven to rotate by the radiator fan 22, and then the belt 12 is driven to rotate. At the same time, the belt 12 drives the transmission pulley 13 to rotate. During the rotation of the transmission pulley 13, the cross plug 14 is driven to rotate. And the cross plug 14 is inserted into the cross slot 16. Further, the cross plug 14 drives the T-shaped rotating block 15 to rotate. At the same time, the T-shaped rotating block 15 drives the first bevel gear 17 to rotate. During the rotation of the first bevel gear 17, it meshes and drives the transmission bevel gear 64 to rotate, and then drives the rotating shaft 63 to rotate. During the rotation of the rotating shaft 63, it drives the transmission bevel gear 64 to rotate, and then meshes and drives the driven bevel gear 65 to rotate. At the same time, the driven bevel gear 65 drives the cleaning blade 66 to rotate. And brushes 20 are provided at both ends of the cleaning blade 66. And the brushes 20 are made of RP thermoplastic rubber material. Further, it can clean the dust on the surface of the GPU main board 1. And the brushes 20 are soft and heat-resistant. Thus, when cleaning the dust on the surface of the GPU main board 1, it can prevent the brushes 20 from scratching the surface of the GPU main board 1, affecting the operation of the GPU and reducing the service life of the GPU. At the same time, the brushes 20 sweep and convey the dust into the collection port 9, so as to facilitate the centralized collection of dust, avoid dust adhering to the surface of the semiconductor heat conducting sheet 10, and further affect the heat conduction and heat dissipation effect of the semiconductor heat conducting sheet 10. It solves the problem that the existing automatic cleaning device for the surface of the GPU usually needs to shut down the host when cleaning the GPU, and then uses a brush and a small hair dryer to clean the GPU. And this operation method is cumbersome and affects the operation of the computer. Moreover, this cleaning method easily causes dust to enter the GPU internal, resulting in short circuit damage of the GPU and other situations.

[0028] As Figure 1 、 Figure 5 and Figure 6 shown, a communication groove 11 is provided on the inner wall of the heat dissipation port 5. A transmission pulley 13 is rotatably connected to the inner cavity of the communication groove 11. One end of the transmission pulley 13 penetrates through the heat dissipation cover 4 and is fixedly connected with a cross plug 14. And the cross plug 14 is inserted and installed with the cross slot 16.

[0029] As Figure 1 、 Figure 5 and Figure 6 shown, the outer part of the driving pulley 13 is drivingly connected with a belt 12. One end of the belt 12 is drivingly connected with a driven pulley 24, and one end of the driven pulley 24 is fixedly connected to the rotating shaft of the radiator fan 22. Embodiment 2

A drawer box 8 is slidably connected inside the sliding groove 7, and the collection port 9 communicates with the inner cavity of the drawer box 8. The collection port 9 is used for collecting and storing the dust cleaned.

[0031] As Figures 5 to 6 and Figures 8 to 9 shown, two guide plates 25 are symmetrically and fixedly connected to the inner wall of the collection port 9. The two guide plates 25 are arranged in an inverted triangle. A plurality of air outlet holes 26 are provided on the inner wall of the drawer box 8.

[0032] Specifically, after the dust is swept into the collection port 9 by the brush 20, the dust will fall into the inner cavity of the drawer box 8 through between the two guide plates 25. The arrangement of the two guide plates 25 can guide the dust into the drawer box 8, and at the same time, the two guide plates 25 can be used to block the dust entering the drawer box 8, preventing the dust in the drawer box 8 from being blown out of the drawer box 8 by the radiator fan 22 and affecting the collection effect.

[0033] As Figures 5 to 6 and Figures 8 to 9 shown, semiconductor heat conducting sheets 10 are also installed on the upper and lower end surfaces of the GPU main board 1, and the semiconductor heat conducting sheets 10 are used for conducting the heat generated by the operation of the GPU main board 1.

[0034] As Figures 5 to 6 and Figures 8 to 9 shown, a diversion cover 27 is installed on the lower end surface of the GPU main board 1, and the diversion cover 27 is used for guiding the flow direction of the air, increasing the heat dissipation and cooling efficiency of the GPU main board 1. A mesh cover 19 is installed at the bottom of the inner cavity of the heat dissipation port 5.

[0035] Specifically, when using the cooling fan 22 to blow air on the GPU motherboard 1 for heat dissipation and temperature reduction, the air blown by the cooling fan 22 on the GPU motherboard 1 will be blown into the drawer box 8 through the collection port 9. The inner wall of the drawer box 8 is provided with air outlet holes 26, so that the air blown by the cooling fan 22 is blown out through the air outlet holes 26 and flows into the inner cavity of the diversion cover 27, and is blown out through one end of the diversion cover 27. After the air flows through the inner cavity of the diversion cover 27, it will blow the semiconductor heat conducting sheet 10 on the lower end surface of the GPU motherboard 1, thereby blowing the heat in the semiconductor heat conducting sheet 10, achieving the effect of quickly reducing the temperature of the GPU motherboard 1, and solving the problem that when the existing automatic cleaning device on the surface of the GPU is cleaning the dust on the GPU motherboard, it is inconvenient to blow and clean the inside of the GPU motherboard, resulting in a large amount of dust accumulating inside the GPU, affecting the heat dissipation effect of the GPU motherboard, and it is difficult to clean the large amount of dust accumulated inside the GPU.

[0036] Working principle: When cleaning the GPU motherboard 1, the cleaning blade 66 is driven to rotate while the GPU motherboard 1 is running. Since brushes 20 are provided at both ends of the cleaning blade 66 and the brushes 20 are made of RP thermoplastic rubber material, it can clean the dust on the surface of the GPU motherboard 1, and is soft and heat-resistant, so that when cleaning the dust on the surface of the GPU motherboard 1, it can prevent the brushes 20 from scratching the surface of the GPU motherboard 1, affecting the operation of the GPU and reducing the service life of the GPU. When the cooling fan 22 is running, the driven pulley 24 is driven to rotate by the cooling fan 22, then the belt 12 is driven to rotate, and at the same time the belt 12 drives the driving pulley 13 to rotate. During the rotation of the driving pulley 13, the cross plug 14 is driven to rotate. The cross plug 14 is inserted into the cross slot 16, so that the cross plug 14 drives the T-shaped rotating block 15 to rotate. At the same time, the T-shaped rotating block 15 drives the first bevel gear 17 to rotate. During the rotation of the first bevel gear 17, it meshes with and drives the transmission bevel gear 64 to rotate, then drives the rotating shaft 63 to rotate. During the rotation of the rotating shaft 63, it drives the transmission bevel gear 64 to rotate, then meshes with and drives the driven bevel gear 65 to rotate. At the same time, the driven bevel gear 65 drives the cleaning blade 66 to rotate. Brushes 20 are provided at both ends of the cleaning blade 66 and the brushes 20 are made of RP thermoplastic rubber material, so that it can clean the dust on the surface of the GPU motherboard 1, and is soft and heat-resistant, so that when cleaning the dust on the surface of the GPU motherboard 1, it can prevent the brushes 20 from scratching the surface of the GPU motherboard 1, affecting the operation of the GPU and reducing the service life of the GPU. At the same time, the brushes 20 sweep and convey the dust into the collection port 9, so as to facilitate the centralized collection of dust and avoid the dust adhering to the surface of the semiconductor heat conducting sheet 10, thereby affecting the heat conduction and heat dissipation effect of the semiconductor heat conducting sheet 10. When using the cooling fan 22 to blow air on the GPU main board 1 for heat dissipation and temperature reduction, the air blown by the cooling fan 22 on the GPU main board 1 will be blown into the drawer box 8 through the collection port 9. The inner wall of the drawer box 8 is provided with air outlet holes 26, so that the air blown by the cooling fan 22 is blown out through the air outlet holes 26 and flows into the inner cavity of the diversion cover 27, and is blown out through one end of the diversion cover 27.
