Technical Field

[0001] The invention relates to the technical field of computer mainframe cases, and in particular to a computer mainframe case with dust-proof and dust-cleaning functions. Background Art

[0002] Computer is commonly known as computer, which is an electronic computing machine used for high-speed calculation. It can perform numerical calculation, logical calculation and storage memory function. It is a modern intelligent electronic device that can run according to the program and automatically and quickly process massive data. It is composed of hardware system and software system. A computer without any software installed is called a bare metal.

[0003] After searching, the Chinese patent number CN109976468A discloses a dustproof computer mainframe case, which belongs to the field of computer technology. It includes a case body, a dustproof net arranged on the case body, a cleaning device arranged on the case body and used to clean the dustproof net, and a dust discharge device connected to the cleaning device and used to discharge dust from the case body. The dustproof computer mainframe case of the present invention can timely clean the dust inside the mainframe case by arranging the cleaning device and the dust discharge device, thereby improving the ventilation and heat dissipation effect of the mainframe case.

[0004] During the use of the above device, the dustproof net is cleaned reciprocatingly by controlling the cleaning rod through the cam, and the dust removal rod is controlled by the connecting rod to remove dust during the cleaning process. However, the cleaning rod does not reciprocate at a uniform speed during the cleaning process, which causes a sudden change in the movement acceleration of the dust removal rod. Subsequently, during the dust removal process, the dust in the dust removal trough is spread all around the main chassis, which not only pollutes the environment, but also reduces the dust prevention effect. Therefore, a computer main chassis with dust prevention and cleaning functions is proposed. Summary of the invention

[0023] 2. In the present invention, the wind inside the mainframe case is discharged through the exhaust port through the first channel through the second channel. When the wind circulates inside the first channel, it passes through the through hole. According to Bernoulli's principle, when the computer is just started or there is a lot of dust on the dust screen at the air inlet, the airflow through the first channel is small, and the air pressure inside the hollow column remains unchanged. Under the action of the spring, the sliding plate causes the switch control lever to control the normally open switch to form an open and closed state, and then the control motor is started to clean the surface of the dust screen at the air inlet. When the computer is started for a period of time or there is less dust on the surface of the dust screen at the air inlet, the airflow through the first channel is large, and the air pressure inside the hollow column becomes small, thereby controlling the sliding plate to move downward. The movement of the sliding plate drives the switch control lever away from the normally open switch, so that the normally open switch changes from open to closed, and then controls the control motor to close, thereby avoiding meaningless startup of the control motor to increase the temperature inside the mainframe case.

[0034] See also Figure 1-Figure 8 As shown, the present invention is a computer mainframe case with dust-proof and dust-cleaning functions, comprising:

[0035] The mainframe case 1 is a rectangular structure with a hollow interior. The mainframe case 1 is provided with components such as a motherboard, a hard disk, and a graphics card, and an air inlet 2 is provided on the side of the mainframe case 1. A dustproof net is provided at the air inlet 2. An air outlet 4 is provided on the side of the mainframe case 1 away from the air inlet 2. A dustproof net is provided at the air outlet 4. A control motor 5 is provided inside the mainframe case 1. A control shaft 21 is provided at the output end of the control motor 5. A reciprocating cleaning mechanism for cleaning the surface of the air inlet 2 is provided outside the control shaft 21. The reciprocating cleaning mechanism includes The reciprocating block 23 is slidably connected between the mainframe housing 1 and the reciprocating block 23. A second cleaning block 27 for cleaning the surface of the air inlet 2 is fixedly connected to the outside of the reciprocating block 23. An incomplete tooth 22 is fixedly connected to the side of the control shaft 21 away from the control motor 5. A first reciprocating tooth 24 and a second reciprocating tooth 25 are arranged inside the reciprocating block 23. When the reciprocating block 23 slides upward for cleaning, the incomplete tooth 22 is meshed with the first reciprocating tooth 24. When the reciprocating block 23 slides downward for cleaning, the incomplete tooth 22 is meshed with the second reciprocating tooth 25.

[0036] A ash cleaning pool 3 is arranged on one side of the mainframe housing 1 close to the air inlet 2, and an ash cleaning mechanism for cleaning the ash cleaning pool 3 is arranged outside the mainframe housing 1. The ash cleaning mechanism includes a full gear 9 arranged inside the mainframe housing 1, and the mainframe housing 1 and the full gear 9 are rotatably connected. An intermittent reciprocating assembly for transmission is arranged between the control shaft 21 and the full gear 9, and the intermittent reciprocating assembly controls the intermittent reciprocating rotation of the full gear 9. The full gear 9 is externally transmission-connected with a conveyor belt 17, and the conveyor belt 17 is externally fixedly connected with a first cleaning block 18 useful for cleaning the ash cleaning pool 3;

[0037] A control mechanism for controlling the start of the control motor 5 is provided on one side of the main chassis 1 close to the exhaust port 4. When the air volume passing through the exhaust port 4 becomes smaller, that is, the computer just starts to work or there is too much dust on the surface of the air inlet 2 affecting the air volume, the control mechanism controls the start of the control motor 5.

[0038] The working principle of a computer mainframe case with dust-proof and dust-cleaning functions proposed by the present invention is as follows: mounting holes for embedding dust-proof nets are provided around the air inlet 2 and the air outlet 4 of the mainframe case 1; the dust-proof nets have a plurality of mesh holes for airflow to pass through; the mesh holes have a small diameter and play a certain dust-proof role; when the cooling fan inside the mainframe case 1 is running, airflow is generated; external air enters the mainframe case 1 through the dust-proof net at the air inlet 2 to cool down the components inside the mainframe case 1; after long-term use, dust is adhered to the dust-proof net at the air inlet 2; in order to prevent dust from clogging the mesh holes of the dust-proof net at the air inlet 2, a reciprocating cleaning mechanism is used to clean the dust on the dust-proof net at the air inlet 2, that is, the control motor 5 controls the control shaft 21; the control shaft 21 controls the operation of the reciprocating cleaning mechanism; the control shaft 21 controls the rotation of the incomplete teeth 22; when the incomplete teeth 22 rotate, they first mesh with the first reciprocating teeth 24 to connect; and then the incomplete teeth 24 mesh with the first reciprocating teeth 24 to move. The first reciprocating tooth 24 drives the reciprocating block 23 to move downward, and the reciprocating block 23 moves downward to drive the second cleaning block 27 to move downward for cleaning. When the second cleaning block 27 follows the reciprocating block 23 to move to the lowest position, the incomplete tooth 22 no longer meshes with the first reciprocating tooth 24. At this time, there is no transmission between the incomplete tooth 22 and the reciprocating block 23, that is, the second cleaning block 27 is stationary. At this moment, the dust falls into the cleaning pool 3, and the external influence is relatively small. After the incomplete tooth 22 continues to rotate, the incomplete tooth 22 is meshed and connected with the second reciprocating tooth 25. Then the second reciprocating tooth 25 rotates to drive the reciprocating block 23 to move upward, and the reciprocating block 23 moves upward to drive the second cleaning block 27 to move upward for cleaning. When the second cleaning block 27 follows the reciprocating block 23 to move to the highest position, the incomplete tooth 22 no longer meshes with the second reciprocating tooth 25. At this time, there is no transmission between the incomplete tooth 22 and the reciprocating block 23, that is, the second cleaning block 27 is stationary, and cleaning is achieved over and over again.

[0039] The cleaned dust falls into the cleaning pool 3, and then the dust in the cleaning pool 3 is cleaned away by the cleaning mechanism, that is, the control shaft 21 controls the full gear 9 to intermittently reciprocate through the intermittent reciprocating assembly, and the intermittent reciprocating rotation of the full gear 9 controls the conveyor belt 17 to control the first cleaning block 18 to intermittently reciprocate, and the first cleaning block 18 intermittently reciprocates to clean the dust in the cleaning pool 3. The intermittent setting prevents the dust from being scattered during the reciprocating cleaning process of the first cleaning block 18.

[0041] In this embodiment, the second cleaning brush 28 moves on the surface of the dustproof net at the air inlet 2 to brush off the dust attached to the dustproof net at the air inlet 2. The brushed dust is collected in the cleaning pool 3. The cleaning trough 20 is opened outside the cleaning pool 3 for regular cleaning or discharge of collected dust. The main function of the first cleaning brush 19 is to clean the dust inside the cleaning trough 20 to ensure that dust will not accumulate in the cleaning trough 20 and affect its collection effect. The first cleaning brush 19 and the second cleaning brush 28 work together to maintain cleanliness.

[0042] In one embodiment, for the above-mentioned control motor 5, a first bevel gear 26 is provided at the output end of the control motor 5, and a second bevel gear 38 is meshedly connected to the side of the first bevel gear 26 away from the control motor 5, the second bevel gear 38 is fixedly connected to the control shaft 21, and the control shaft 21 is rotationally connected to the main housing 1.

[0043] In this embodiment, the control motor 5 controls the first bevel gear 26 to rotate. Since the first bevel gear 26 is meshed with the second bevel gear 38 , the rotation of the first bevel gear 26 drives the second bevel gear 38 to rotate, and the rotation of the second bevel gear 38 drives the control shaft 21 to rotate.

[0044] In one embodiment, for the above-mentioned intermittent reciprocating component, the intermittent reciprocating component includes a first connecting rod 6 arranged outside the control shaft 21, the control shaft 21 and the first connecting rod 6 are fixedly connected, the first connecting rod 6 is externally rotatably connected to the second connecting rod 7, the second connecting rod 7 is externally rotatably connected to the fan blade plate 8, a fixed shaft 15 is fixedly connected inside the main housing 1, the fixed shaft 15 and the fan blade plate 8 are rotatably connected, the second connecting rod 7 is externally slidably connected to the fan-shaped rack 10, and the fan blade plate 8 is fixedly connected to the first limit block 11 and the second limit block 12 on the side close to the fan-shaped rack 10.

[0045] In one embodiment, for the above-mentioned sector rack 10, the sector rack 10 is meshingly connected with the full gear 9, and the full gear 9 is fixedly connected to the outside with a third connecting rod 16 for controlling the transmission of the conveyor belt 17.

[0046] In this embodiment, the start control motor 5 drives the control shaft 21 to rotate, the rotation of the control shaft 21 drives the first connecting rod 6 to rotate, the rotation of the first connecting rod 6 drives the second connecting rod 7 to rotate, because the fan blade plate 8 is rotatably connected to the main frame 1 through the fixed shaft 15, and at the same time, the second connecting rod 7 is detached from the rotational connection between one side of the first connecting rod 6 and the fan blade plate 8, then the first connecting rod 6 controls the fan blade plate 8 to reciprocate through the second connecting rod 7, that is, the first connecting rod 6, the second connecting rod 7 and the fan blade plate 8 form a four-bar linkage, and the fan blade plate 8 The fan blade 8 rotates back and forth. During the reciprocating rotation of the fan blade 8, due to the meshing connection between the fan-shaped rack 10 and the full gear 9, the rotation of the fan blade 8 drives the fan-shaped rack 10 to control the rotation of the full gear 9. However, when the fan blade 8 rotates, the first limit block 11 or the second limit block 12 is released to the fan-shaped rack 10. At this time, the fan blade 8 rotates, and the first limit block 11 or the second limit block 12 drives the fan-shaped rack 10 to rotate, and then the rotation of the fan-shaped rack 10 drives the full gear 9 to rotate, and the rotation of the full gear 9 controls the cleaning of dust.

[0047] In one embodiment, for the above-mentioned second connecting rod 7, an adjustment module for changing the amplitude of the intermittent reciprocating component is arranged between the second connecting rod 7 and the fan blade plate 8, and the adjustment module includes a slider 13 arranged outside the second connecting rod 7, and a slide groove 14 is opened outside the fan blade plate 8. The slider 13 is slidingly connected to the slide groove 14, and a fixing member for fixing with the fan blade plate 8 is arranged outside the slider 13.

[0048] In this embodiment, by changing the connection position between the second connecting rod 7 and the fan blade plate 8, the length of the driven rod in the four-bar linkage formed by 6, the second connecting rod 7 and the fan blade plate 8 is changed, thereby changing the swing amplitude of the driven rod.

[0049] In one embodiment, for the above-mentioned control mechanism, the control mechanism includes a first channel 29 arranged outside the exhaust port 4, a hollow column 31 is fixedly connected to the outside of the first channel 29, a sliding plate 32 is slidably connected to the inside of the hollow column 31, a normally open switch 35 for controlling the control motor 5 to work is arranged inside the hollow column 31, and a switch control rod 34 for controlling the normally open switch 35 to switch on and off is arranged on the side of the sliding plate 32 close to the normally open switch 35.

[0050] In one embodiment, for the first channel 29 , a through hole 37 is provided on one side of the first channel 29 close to the hollow column 31 , and the gas inside the first channel 29 is connected to the gas inside the hollow column 31 through the through hole 37 .

[0051] In one embodiment, for the hollow column 31 , a fixing rod 36 is fixedly connected to a side of the hollow column 31 away from the first channel 29 , and a spring 33 is provided between the fixing rod 36 and the sliding plate 32 .

[0052] In one embodiment, for the first channel 29 , a side of the first channel 29 away from the air outlet 4 is fixedly connected to the second channel 30 , and an opening of the second channel 30 on a side away from the first channel 29 gradually increases.

[0053] In this embodiment, the wind inside the mainframe case 1 passes through the second channel 30 to the first channel 29 and then is discharged through the exhaust port 4. The wind enters the first channel 29 through the second channel 30, which increases the wind speed. When the wind circulates inside the first channel 29, it passes through the through hole 37. According to the Bernoulli principle, when the computer is just started or there is a lot of dust on the dustproof net at the air inlet 2, the air flow through the first channel 29 is small, and then through the through hole 37, the air pressure inside the corresponding hollow column 31 remains unchanged, and the sliding plate 32, under the action of the spring 33, causes the switch control rod 34 to control the normally open switch 35 to form In the open and closed state, the control motor 5 is started to clean the surface of the dust screen at the air inlet 2. When the computer is started for a period of time or there is less dust on the surface of the dust screen at the air inlet 2, the air flow through the first channel 29 is large, and the air pressure inside the corresponding hollow column 31 becomes smaller through the through hole 37, thereby controlling the sliding plate 32 to move downward. The movement of the sliding plate 32 drives the switch control rod 34 away from the normally open switch 35, so that the normally open switch 35 changes from open to closed, thereby controlling the control motor 5 to be closed, thereby avoiding meaningless startup of the control motor 5 to increase the temperature inside the main chassis 1.
