Description

Technical Field

[0001] The utility model relates to the technical field of computer mainframe cases, in particular to a computer case equipped with a dust collecting structure. Background Art

[0002] When the computer host is running, due to the action of the internal cooling fan, external dust will enter the chassis host through the air inlet. If the internal components of the host work in a dusty environment for a long time, the service life of the internal parts of the host will be shortened and heat dissipation will also be affected.

[0003] Therefore, more and more hosts will install dust-proof components at the air inlet of the host to reduce dust from falling on the host components, such as: installing a filter on the inner wall of the air inlet and then cleaning the filter regularly.

[0004] However, with this simple dust-proof structure, dust will slowly adhere to the filter when the host is running. When cleaning, a large amount of dust will enter the inside of the host when it is shaken off, causing dust accumulation.

[0005] Therefore, a computer host overall structure is proposed in the Chinese patent publication number: CN220730731U. In this patent, during heat dissipation and ventilation, a part of the dust in the air will enter the dust collecting tank through the top plate with the airflow, and under the filtering action of the dust filter layer plate combined at the bottom of the dust collecting tank, effective dust adsorption, filtering and collection operations are performed, thereby preventing dust in the air from entering the interior of the computer host case and reducing the accumulation of dust on the motherboard components.

[0006] However, the device relies on a dust filter layer plate to filter dust. The single-sided dust filtering not only has a slow filtering efficiency, but also the filter holes are blocked quickly. The dust filter layer plate needs to be cleaned frequently, which brings inconvenience to users. Utility Model Content

[0007] The utility model aims to provide a computer case equipped with a dust collecting structure to solve the above problems existing in the prior art.

[0008] The technical solution of the utility model to solve the above technical problems is as follows:

[0009] A computer case equipped with a dust collection structure, comprising a case shell with an opening at the top, and an air intake dust collection structure arranged at the top opening of the case shell;

[0011] The air intake scoop is nested in the top opening of the chassis shell, the air intake pipe is movably inserted into the interior of the air intake scoop from the bottom of the air intake scoop, the filter cover is a square filter box made of a plurality of filter plates, and is sleeved on the top of the air intake pipe, and the top cover is set on the top of the air intake scoop.

[0012] The beneficial effects of the utility model are as follows: when the host fan is running, external air enters the air intake hopper, and then is filtered through the filter cover, so that pure air enters the chassis shell through the air intake pipe, and the intercepted dust will be collected by the air intake hopper, thereby preventing the dust in the air from falling on other components in the chassis shell; and, since the filter cover is used to filter the air, compared with the traditional plate filter, the receiving area of ​​the air and the filter cover is larger than the plate filter, and the air can penetrate into the filter cover from all directions of the filter cover, effectively improving the filtering efficiency of the filter cover. At the same time, more multi-faceted filtering methods can also delay the time when the filter cover is completely blocked, which can effectively reduce the user's cleaning frequency, thereby improving the user experience.

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] See also Figure 1-5 , Embodiment 1 of the utility model, a computer case equipped with a dust collection structure, comprises a case shell 1 with an opening at the top, an air intake dust collection structure 2 arranged at the top opening of the case shell 1, and a magnetic attraction ring 6 arranged on the top of the outer wall of the case shell 1;

[0028] The air intake dust collection structure 2 includes an air intake hopper 21, an air intake pipe 22, a filter cover 23 and a top cover 24;

[0029] The air intake scoop 21 is nested in the top opening of the chassis shell 1, and the air intake pipe 22 is movably inserted into the air intake scoop 21 from the bottom of the air intake scoop 21. The filter cover 23 is a square filter box made of several filter plates and is sleeved on the top of the air intake pipe 22. The top cover 24 is inserted on the top of the air intake scoop 21.

[0030] In this embodiment, when the main engine fan is running, the external air enters the air intake hopper 21, and then passes through the filter cover 23 to filter, so that the pure air enters the chassis shell 1 through the air intake pipe 22, and the intercepted dust is collected by the air intake hopper 21, so as to prevent the dust in the air from falling on other components in the chassis shell 1;

[0031] Furthermore, since the filter cover 23 is used to filter the air, compared with the traditional plate filter, the receiving area between the air and the filter cover 23 is larger than that of the plate filter, and the air can penetrate into the filter cover 23 from all directions of the filter cover 23, which effectively improves the filtering efficiency of the filter cover 23. At the same time, more multi-faceted filtering methods can also delay the time when the filter cover 23 is completely blocked, which can effectively reduce the user's cleaning frequency, thereby improving the user experience.

[0032] By adding the top cover 24, an additional top interception plate can be provided to the chassis shell 1, which can intercept naturally falling dust to a certain extent, and at the same time provide the chassis shell 1 with an additional placement platform for users to place other items.

[0033] When cleaning dust, the air intake hopper 21 can be directly lifted upward, and then the air intake hopper 21, the air intake pipe 22, and the filter cover 23 can be quickly disassembled by pulling, so that each component in the air intake dust collection structure 2 can be cleaned.

[0034] Embodiment 2 of the utility model is a computer case equipped with a dust collection structure. Based on embodiment 1, the air inlet hopper 21 includes a frame 211 and a hopper body 212; the hopper body 212 is welded to the bottom of the frame 211 and embedded in the chassis shell 1, and an iron ring that is attracted to the magnetic ring 6 is provided on the bottom wall of the frame 211 and located on the periphery of the hopper body 212.

[0035] It should be noted here that the frame 211 is a rectangular frame, the outer length and outer width of the frame 211 are greater than the outer length and outer width of the top surface of the chassis shell 1, the inner length and inner width of the frame 211 are smaller than the inner length and inner width of the top surface of the chassis shell 1, and the bucket body 212 is a hollow step-shaped, and the length and width of the top surface of the bucket body 212 match the inner length and inner width of the top surface of the chassis shell 1. Such a design allows the air intake bucket 21 to be directly placed at the top opening of the chassis shell 1 without careful adjustment, which is convenient for users to assemble the air intake dust collection structure 2.

[0036] At the same time, by installing an iron ring adsorbed with the magnetic ring 6 on the bottom wall of the frame 211, the stability of the entire air intake dust collection structure 2 can be guaranteed after being installed on the top of the chassis shell 1.

[0037] Embodiment 3 of the present utility model is a computer case equipped with a dust collection structure. Based on any embodiment of embodiment 2, the air intake hopper 21 also includes three docking rings 213 fixed at the bottom of the hopper body 212 at equal intervals. The number of air intake pipes 22 is the same as the number of docking rings 213 and corresponds one to one. The air intake pipe 22 includes a tube body 221 passing through the docking ring 213 and the bottom wall of the hopper body 212. A limiting ring 222 is fixedly installed on the surface of the tube body 221 and below the docking ring 213.

[0038] In this embodiment, a damping ring pad is mounted on the outer surface of the intake pipe 22. When the intake pipe 22 is inserted from the bottom of the docking ring 213, the docking ring 213 and the intake pipe 22 are tightly fitted due to the damping ring pad, so that the docking ring 213 and the intake pipe 22 will not automatically become disconnected. The function of the limiting ring 222 is to ensure that the insertion depth of the three intake pipes 22 is uniform, thereby facilitating the subsequent docking of the filter cover 23.

[0039] Embodiment 4 of the present invention is a computer case equipped with a dust collection structure. Based on any one of embodiments 1-3, the filter cover 23 includes a cover body 231 and a limiting rod 232; three pipe openings adapted to the tube body 221 are arranged side by side on the bottom wall of the cover body 23, and a limiting rod 232 spanning the three pipe openings is fixedly installed on the inner bottom wall of the cover body 23.

[0040] By installing the limiting rod 232 on the inner bottom wall of the cover body 23, the user can prevent the intake pipe 22 from going too deep into the filter cover 23 when the filter cover 23 is placed on the top of the intake pipe 22, thereby avoiding affecting the intake effect of the intake pipe 22.

[0041] Embodiment 5 of the utility model is a computer case equipped with a dust collection structure. Based on any one of embodiments 1-4, the air inlet hopper 21 also includes a docking tube 214 fixed to the four corners of the top surface of the frame 211, and the top cover 24 includes a top plate 241 and four plug posts 242 distributed at the four corners of the bottom wall of the top plate 241, and the four plug posts 242 are distributed and inserted into the corresponding docking tubes 214.

[0042] To facilitate installation and removal of the top cover, in a specific implementation, the surface of the plug post 242 is wrapped with a resistance band, so that the plug post 242 can be more tightly inserted into the docking tube 214.

[0043] Embodiment 6 of the present utility model is a computer case equipped with a dust collection structure. Based on any one of embodiments 1-5, an embedded groove 3 is provided on the side wall of the case shell 1, an exhaust port 4 passing through the wall of the embedded groove 3 is provided on the wall of the embedded groove 3, a flexible filter plate 5 is attached to the embedded groove 3, and a magnetic strip that can be adsorbed on the case shell 1 is fixedly installed on the edge of the flexible filter plate 5 close to the wall of the embedded groove 3.

[0044] Installing a flexible filter plate 5 at the air outlet 4 can effectively prevent dust from entering the interior of the chassis housing 1 through the air outlet 4 when the chassis housing 1 is stationary.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
