Description

Technical Field

[0001] The utility model relates to the field of computer dust prevention, in particular to a dust-proof case for a computer. Background Art

[0002] Computer, commonly known as computer, is a modern electronic computing machine used for high-speed calculations. It can perform numerical calculations, logical calculations, and has storage and memory functions. It is a modern intelligent electronic device that can run according to programs and automatically and quickly process massive amounts of data. After long-term use, a lot of dust will fall into the computer case, and too much dust will easily affect the heat dissipation and operation of the computer.

[0003] Most of the existing dust-proof chassis will have a dust-proof structure installed at the heat dissipation holes or filters of the chassis. Even so, it is difficult to ensure that a large number of chassis are completely sealed and dust-proof to ensure good heat dissipation. In this way, dust will still fall into the inside of the chassis after a long period of use, so that the inside of the chassis still needs to be opened regularly for dust cleaning. Utility Model Content

[0004] The purpose of the utility model is to provide a dustproof case for a computer in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A dustproof computer case includes a case frame, one end of which is provided with a heat dissipation mechanism for ventilation and heat dissipation inside the case, and a cover mechanism for cleaning the case.

[0007] The capping mechanism includes a mounting frame, which is fixed at the front end of the chassis frame. The chassis cover is fixed to the front end of the mounting frame by bolts. Two rotating rods are rotatably connected in the middle of the chassis cover. Elastic iron rolls are arranged in the middle of the two rotating rods. Glass plates are arranged on both sides of the elastic iron rolls, and the glass plates are fixed to the chassis cover. A sliding frame is fixed in the middle of the corresponding ends of the two elastic iron rolls. A front extension frame is fixed at the front end of the sliding frame. A fan is installed inside the front extension frame. An air outlet hopper is fixed at the output end of the fan. A suction pump is installed at the lower end of the fan. A dust hopper is fixed at the input end of the suction pump, and a dust filter bag is fixed at the output end of the dust hopper.

[0008] Preferably: a clockwork spring is fixed in the middle of the elastic iron roll, and the elastic iron roll is rolled up to the periphery of the rotating rod through the clockwork spring.

[0009] Preferably, the sliding frame is in an I-shape, and the sliding frame is slidably connected to the chassis cover.

[0010] Preferably, the output end of the fan and the input end of the suction pump are both oriented toward the inside of the chassis frame, and the dust collecting hopper at the input end of the suction pump is narrow in front and wide in the back.

[0011] Preferably, the output end of the air outlet scoop is in a flat and long shape, and the output port of the air outlet scoop is narrower in the middle and wider at both ends.

[0012] Preferably, the heat dissipation mechanism comprises a dust filter, which is fixed to one end of the chassis frame, and a socket plate is arranged below the dust filter, and the socket plate is fixed to the chassis frame.

[0013] The beneficial effects compared with the prior art are as follows:

[0014] When dust that may affect the operation or heat dissipation of the computer appears inside the chassis frame, the front extension frame is first pushed to the top through the sliding connection between the sliding frame and the chassis cover, and then the fan and the suction pump are started. After the fan is started, wind can be generated to blow into the chassis frame through the air outlet scoop. The output end of the air outlet scoop is flat and long, and the output port of the air outlet scoop is narrow in the middle and wide at both ends, so that the wind blown out through the air outlet scoop is stronger, so that the dust in the chassis is blown up, and then the suction pump is started to allow the blown dust to be sucked into the dust filter bag through the dust collecting hopper, and then the dust is collected into the inside of the dust filter bag through filtration by the dust filter bag, and then the front extension frame is pushed from top to bottom to perform a comprehensive dust cleaning process on the chassis frame. In this way, even if there is dust in the chassis frame, there is no need to open the chassis to clean it. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 4 As shown, a dustproof computer case includes a case frame 1, a ground contact mechanism 2 is installed at the lower end of the case frame 1, a heat dissipation mechanism 3 for ventilation and heat dissipation inside the case is installed at one end of the case frame 1, and also includes a covering mechanism 4 for cleaning the case.

[0026] In this embodiment, the ground contact mechanism 2 includes four ground contact blocks 21, which are respectively fixed at the four corners of the lower end of the chassis frame 1, and a rubber pad 22 is fixed at the lower end of the ground contact block 21; the friction provided by the rubber pad 22 can make the chassis frame 1 placed more stably.

[0027] In this embodiment, the heat dissipation mechanism 3 includes a dust filter 31, which is fixed at one end of the chassis frame 1. A socket plate 32 is arranged below the dust filter 31, and the socket plate 32 is fixed to the chassis frame 1. A large amount of dust can be isolated from the outside of the chassis frame 1 through the filtering of the dust filter 31, and the ventilation of the dust filter 31 can enable the chassis frame 1 to have good heat dissipation.

[0028] In this embodiment, the capping mechanism 4 includes a mounting frame 41, which is fixed to the front end of the chassis frame 1. The front end of the mounting frame 41 is fixed with a chassis cover 42 by bolts. Two rotating rods 44 are rotatably connected in the middle of the chassis cover 42. Elastic iron rolls 45 are arranged in the middle of the two rotating rods 44. A spring is fixed in the middle of the elastic iron rolls 45. The elastic iron rolls 45 are rolled up to the periphery of the rotating rods 44 through the spring. Glass plates 43 are arranged on both sides of the elastic iron rolls 45, and the glass plates 43 are fixed to the chassis cover 42. A sliding frame 46 is fixed in the middle of the corresponding ends of the two elastic iron rolls 45. The movable frame 46 is in an I-shape, and the sliding frame 46 is slidably connected to the chassis cover 42. A front extension frame 47 is fixed to the front end of the sliding frame 46. A fan 48 is installed inside the front extension frame 47. An air outlet 49 is fixed to the output end of the fan 48. The output end of the air outlet 49 is flat and long, and the output port of the air outlet 49 is narrow in the middle and wide at both ends. A suction pump 410 is installed at the lower end of the fan 48. The output end of the fan 48 and the input end of the suction pump 410 are both facing the inside of the chassis frame 1. A dust hopper 411 is fixed to the input end of the suction pump 410. The dust hopper 411 is narrow in front and wide in the back. Dust filter bag 412; when dust that may affect the operation or heat dissipation of the computer appears inside the chassis frame 1, the front frame 47 is first pushed to the uppermost end through the sliding connection between the sliding frame 46 and the chassis cover 42, and the rotating rod 44 is connected to the chassis cover 42 for rotation. When the front frame 47 is pulled up and then moved down, the pulled-out elastic iron roll 45 can block the middle of the chassis cover 42 to prevent a large amount of dust from being blown out from the middle of the chassis cover 42 during operation. Then, the fan 48 and the suction pump 410 are started. After the fan 48 is started, it can generate wind force to blow into the chassis frame 1 through the air outlet 49, and then the fan 48 can be turned on. The output end of the air outlet duct 49 is flat and long, and the output port of the air outlet duct 49 is narrow in the middle and wide at both ends, so that the wind blown out through the air outlet duct 49 is relatively strong, so that the dust in the chassis is blown up, and then the suction pump 410 is started to allow the blown dust to be sucked into the dust filter bag 412 through the dust collecting hopper 411, and then the dust is collected into the interior of the dust filter bag 412 through filtering by the dust filter bag 412, and then the front extension frame 47 is pushed from top to bottom to perform a comprehensive dust cleaning process on the chassis frame 1. In this way, even if there is dust in the chassis frame 1, there is no need to open the chassis to clean it.

[0029] Working principle: after the computer has been used for a long time and has generated a lot of dust, the front extension frame 47 is first pushed to the top through the sliding connection between the sliding frame 46 and the chassis cover 42, and the rotating connection between the rotating rod 44 and the chassis cover 42 is made. When the front extension frame 47 is pulled up and then moved down, the pulled-out elastic iron roll 45 can block the hollow in the middle of the chassis cover 42 to prevent a lot of dust from being blown out from the middle of the chassis cover 42 during operation. Then, the fan 48 and the suction pump 410 are started. After the fan 48 is started, it can generate wind to blow into the chassis frame 1 through the air outlet 49, and then the air outlet 49 is used to blow the dust out of the chassis frame 1. The output end of 49 is flat and long, and the output port of the air outlet 49 is narrow in the middle and wide at both ends, so that the wind blown out through the air outlet 49 is relatively strong, so that the dust in the chassis is blown up, and then the suction pump 410 is started to allow the blown dust to be sucked into the dust filter bag 412 through the dust collecting hopper 411, and then the dust is collected into the interior of the dust filter bag 412 through the filtration of the dust filter bag 412, and then the front extension frame 47 is pushed from top to bottom to perform a comprehensive dust cleaning process on the chassis frame 1. In this way, even if there is dust in the chassis frame 1, there is no need to open the chassis to clean it.
