Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0028] Refer to the attached Figure 1 - attached Figure 8, a computer heat dissipation chassis provided by the utility model includes a computer chassis body 1. A fixed frame 2 is fixedly arranged inside the computer chassis body 1. A dust-proof component is arranged on one side of the fixed frame 2. A fan support frame 3 is fixedly arranged inside the fixed frame 2. Two grooves 4 are opened on one side of the fan support frame 3. A motor 5 is fixedly arranged on one side of the fan support frame 3. The output end of the motor 5 is fixedly connected with a rotating shaft 6. A connecting plate 7 and a heat dissipation fan 17 are fixedly sleeved outside the rotating shaft 6. Two pushing balls 8 and a plurality of anti-friction balls 9 are respectively embedded on one side of the connecting plate 7. A movable plate 10 is sleeved outside the rotating shaft 6. Auxiliary connecting inclined blocks 18 are fixedly arranged at the top and bottom of the movable plate 10. Elastic components are arranged at both ends of the movable plate 10;

[0029] In this implementation scheme, in order to achieve the purpose of both enabling air circulation for heat dissipation and filtering dust in the flowing air, the motor 5 rotates to drive the heat dissipation fan 17 to rotate through the rotating shaft 6. The rotation of the heat dissipation fan 17 accelerates the air circulation, so that the air outside the computer chassis body 1 flows into the computer chassis body 1 through the connecting frame 14. The connecting frame 14 intercepts the dust in the flowing air to prevent the dust in the air from entering the computer chassis body 1, achieving the function of dust prevention while ventilating and dissipating heat;

[0030] Among them, in order to achieve the purpose of cleaning the filter net 16, the following technical scheme is adopted in this device: The dust-proof component includes a connecting frame 14. The connecting frame 14 is embedded in one side wall of the computer chassis body 1 and fixedly connected with one side wall of the computer chassis body 1. One side of the connecting frame 14 is fixedly connected with the fixed frame 2. An installation groove 15 is opened inside the connecting frame 14. A filter net 16 is inserted into the installation groove 15. The filter net 16 is slidably connected with the installation groove 15. After the filter net 16 is used for a long time, some sticky impurities that are difficult to shake off will adhere to it. Drag the filter net 16 to take the filter net 16 out of the installation groove 15, which is convenient for disassembling and cleaning the filter net 16;

[0031] Among them, in order to achieve the purpose of preventing dust from adhering to the filter screen 16, the following technical solutions are adopted in this device: The elastic component includes a fixed rod 11. The fixed rod 11 passes through the movable plate 10 and is fixedly connected to the movable plate 10. A spring 12 is sleeved outside the fixed rod 11. One end of the fixed rod 11 is fixedly provided with a top block 13. The rotating shaft 6 passes through the two side walls of the fan support frame 3 and is connected to the two side walls of the fan support frame 3 through bearings. The pushing balls 8 are respectively in rolling connection with the movable plate 10 and the two auxiliary connection inclined blocks 18. The movable plate 10 is arranged inside the connection frame 14 and is slidably connected to the connection frame 14. One end of the fixed rod 11 extends outside the groove 4 and is slidably connected to the groove 4. The spring 12 is arranged inside the groove 4. One end of the spring 12 is fixedly connected to the groove 4, and the other end of the spring 12 is fixedly connected to the movable plate 10. When the pushing ball 8 rotates and contacts the auxiliary connection inclined block 18, the contracted spring 12 makes the movable plate 10 move towards the connection plate 7 through the elastic force. The movement of the movable plate 10 drives the top block 13 to collide with the filter screen 16 through the fixed rod 11, so that the filter screen 16 is impacted, and then the filter screen 16 vibrates, preventing dust from adhering to the filter screen 16, and further preventing the mesh holes of the filter screen 16 from being blocked by dust, so that the filter screen 16 always remains unobstructed, preventing the situation that air cannot circulate due to the blockage of the filter screen 16, and ensuring the stability of heat dissipation.

[0032] The usage process of this utility model is as follows: When using this utility model, connect to an external power supply. When it is necessary to ventilate and dissipate heat inside the computer case body 1, start the motor 5. The rotation of the motor 5 drives the heat dissipation fan 17 and the connection plate 7 to rotate through the rotating shaft 6. The rotation of the heat dissipation fan 17 accelerates the air circulation, so that the external air of the computer case body 1 flows into the computer case body 1 through the connection frame 14. The connection frame 14 intercepts the dust in the flowing air, preventing the dust in the air from entering the computer case body 1, achieving the function of dust prevention while ventilating and dissipating heat. At the same time, when the connection plate 7 rotates, it drives the pushing ball 8 to rotate. By the pushing ball 8 respectively contacting the movable plate 10 and the auxiliary connection inclined block 18, the position of the movable plate 10 is controlled. When the pushing ball 8 rotates and contacts the auxiliary connection inclined block 18, the contracted spring 12 makes the movable plate 10 move towards the connection plate 7 through the elastic force. The movement of the movable plate 10 drives the top block 13 to collide with the filter screen 16 through the fixed rod 11, so that the filter screen 16 is impacted, and then the filter screen 16 vibrates, preventing dust from adhering to the filter screen 16, and further preventing the mesh holes of the filter screen 16 from being blocked by dust, so that the filter screen 16 always remains unobstructed, preventing the situation that air cannot circulate due to the blockage of the filter screen 16, and ensuring the stability of heat dissipation. Similarly, when the pushing ball 8 rotates to contact the movable plate 10, the movable plate 10 moves in the opposite direction away from the connection plate 7, and then the top block 13 is separated from the filter screen 16, and at the same time, the spring 12 contracts, facilitating the next impact of the top block 13 on the filter screen 16.

[0033] The above are only the preferred embodiments of the present utility model. Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into equivalent technical solutions. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model falls within the scope of protection required by the present utility model.
