Description

Technical Field

[0001] This utility model belongs to the technical field of computer host dust removal auxiliary equipment, specifically relating to a rapid dust removal device for computer hosts. Background Technology

[0002] The computer host is the core component of computer hardware. It typically includes the chassis and the motherboard, central processing unit (CPU), memory, hard drive, graphics card, and other components located inside. The chassis is the physical container for all these electronic components, providing protection and stability. The chassis needs to have air intake and exhaust vents. Chassis are usually rectangular in shape, with air intake vents typically located at the front, side, or top, and exhaust vents usually located at the rear.

[0003] In existing technologies, the computers used by students in computer teaching processes are relatively low-configuration and need to be turned on for extended periods. As a result, dust often accumulates inside the computer cases. After a period of use, the computer needs to be removed and placed in an open area to allow for dust removal using a fan. This method of dust removal is time-consuming, labor-intensive, and pollutes the surrounding environment, making it impractical. Utility Model Content

[0004] This utility model provides a rapid dust removal device for computer hosts, which aims to solve the problem of poor practicality of existing dust removal methods for teaching computer hosts.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a rapid dust removal device for a computer host, comprising:

[0008] The air outlet is connected to the air outlet of the chassis and is pressed against the outer wall of the chassis by the fixing frame.

[0009] The bag filter dust collector has an air inlet and an air inlet. The air inlet is connected to the air inlet duct through a pipe, and the air inlet is connected to the air outlet duct through a pipe. The bag filter dust collector is used to form a circulation channel with the casing. Through the high-speed airflow formed inside the casing, the dust that is raised is discharged and collected.

Each second short strip is in contact with the corresponding first long strip and second long strip. The second short strips are provided with second short strip openings.

[0015] There are four screws, each screw corresponding to the intersection point of the outer matrix structure and the inner matrix structure. Each screw passes through each of the first long slots and each of the first short slots along the first direction and is locked by a nut. Each screw, each of the first long slots, each of the second long slots, each of the first short slots and each of the second short slots enclose and form the clamping space.

[0018] The first flange is arranged around the outer wall of the first square cylinder and located at the open end of the first square cylinder. The first flange is arranged perpendicular to the central axis of the first square cylinder. The first flange is used to be pressed against the side of the chassis by one of the first long strips and the second long strip, or pressed against the upper part of the chassis by two first long strips.

[0019] In one possible implementation, the first flange and the first square cylinder are combined to form a first annular contact surface, and a first sealing gasket is provided on the first annular contact surface.

[0020] In one possible implementation, the air outlet duct includes:

[0021] The second square cylinder has a second cylindrical cavity with one end open, and the open end of the second square cylinder is used to abut against the air outlet of the chassis; the other end of the second square cylinder is provided with a second connecting pipe port;

[0023] In one possible implementation, the second flange and the second square cylinder are combined to form a second annular abutment surface, and a second sealing gasket is provided on the second annular abutment surface.

[0024] In this implementation, the air inlet duct corresponds to the air inlet of the chassis, and the air outlet duct corresponds to the air outlet of the chassis. The air inlet and air outlet ducts are pressed tightly against the outer wall of the chassis by a fixed frame, which ensures that the air inlet duct is stably connected to the air inlet of the chassis and the air outlet duct is stably connected to the air outlet of the chassis. The bag filter can blow high-speed airflow into the circulation channel formed by the bag filter and the chassis, thereby causing the dust inside the chassis to be raised and carried out of the chassis for collection. This reduces manpower and is environmentally friendly. Attached Figure Description

The rapid dust removal device for computer hosts includes a fixed frame 10, an air inlet duct 20, an air outlet duct 30, and a bag filter 50. The fixed frame 10 has a clamping space to accommodate a chassis 40. The air inlet duct 20 is connected to the air inlet of the chassis 40 and is pressed against the outer wall of the chassis 40 by the fixed frame 10. The air outlet duct 30 is connected to the air outlet of the chassis 40 and is pressed against the outer wall of the chassis 40 by the fixed frame 10. The bag filter 50 has an air supply port and an air intake port. The air supply port is connected to the air inlet duct 20 through a pipe, and the air intake port is connected to the air outlet duct 30 through a pipe. The bag filter 50 can form a circulation channel with the chassis 40, and the high-speed airflow generated inside the chassis 40 will export and collect the dust.

[0031] Compared with the prior art, the rapid dust removal device for computer host provided in this embodiment corresponds the air inlet duct 20 to the air inlet of the chassis 40 and the air outlet duct 30 to the air outlet of the chassis 40. The air inlet duct 20 and the air outlet duct 30 are pressed tightly against the outer wall of the chassis 40 by the fixed frame 10. This ensures that the air inlet duct 20 is stably connected to the air inlet of the chassis 40 and the air outlet duct 30 is stably connected to the air outlet of the chassis 40. The bag filter 50 can blow high-speed airflow into the circulation channel formed by the bag filter 50 and the chassis 40, thereby causing the dust inside the chassis 40 to be raised and carried out of the chassis 40 for collection.

[0032] It should be noted that the bag filter 50 has filter bags, and a conveying pump can be installed at the air inlet of the bag filter 50. This technology is existing technology and will not be described in detail here.

[0033] In some embodiments, the aforementioned fixed frame 10 may adopt the following... Figure 2 The structure shown. See also Figure 2The fixed frame 10 includes a first long strip 11, a second long strip 12, a first short strip 13, a second short strip 14, and a screw 15.

The direction of the spacing between the two first long strips 11 is defined as a first direction. Two second long strips 12 are provided, arranged parallel and spaced apart along the first direction, corresponding one-to-one with each first long strip 11, forming an outer matrix structure. Each second long strip 12 has a second long opening. Two first short strips 13 are provided, arranged parallel and spaced apart along the first direction, each contacting a corresponding first long strip 11 and second long strip 12. Each first short strip 13 has a first short opening. Two second short strips 14 are provided, arranged parallel to each other and spaced apart along the first direction. The two second short strips 14 and the two first short strips 13 form an inner matrix structure. Each second short strip 14 contacts the corresponding first long strip 11 and second long strip 12. Each second short strip 14 has a second short slot. Four screws 15 are provided, each screw 15 corresponding to the intersection point of the outer matrix structure and the inner matrix structure.

The screws 15, the first long strips 11, the second long strips 12, the first short strips 13, and the second short strips 14 enclose a clamping space.

[0034] The corresponding first long strip 11, second long strip 12, first short strip 13, and second short strip 14 can form a grid, as shown in the figure. Figure 2 The two well grids are locked by four screws 15, which ensures the clamping of the chassis 40 and also ensures the fixation of the air inlet duct 20 and the air outlet duct 30.

[0035] The design of the first long slot, the second long slot, the first short slot, and the second short slot also allows for adjustment of the clamping space, thus adapting to different host chassis 40.
