Description
[technical field]
The utility model is about the dust-proof mechanism of a kind of dust-proof mechanism, particularly a kind of notebook computer.
[background technology]
Along with science and technology is constantly progressive, it also is accurate day by day developing each class of electronic devices that at present, yet the also easier usefulness that influences its inner strength member because of the invasion of dust is even cause mechanical disorder.
Under the normal condition, dust in air density is lower than 30mg/m3, but with regard to notebook computer, if dust is in case along with air enters its main frame inside, just may cause damage to it.Especially serious in air pollution, active volcano arranged or have under the particular surroundings such as sandstorm, need effective dust-proof mechanism really badly.For example industrial notebook computer because environment for use is special, must use being full of under the environment of dust, and when particularly using the connectivity port, dust is easy to therefore enter main frame inside, and causes main frame to damage.Yet previous design utilizes cover plate, directly the connectivity port being covered in, thus under dusty environment, be to use the connectivity port mostly, very inconvenience really concerning the user.
[summary of the invention]
Problem in view of prior art, the utility model proposes a kind of notebook computer dust-proof mechanism, utilize the principle of pressure differential, the notebook host pressure inside is kept greater than external pressure, reach dustproof purpose, and, when open the connectivity port, dust can not invaded notebook computer inside yet, and the user will be more convenient in the use.
Notebook computer dust-proof mechanism provided by the utility model, be to be incorporated into the air port, filter screen, the air compressor fan, air duct and air outlet, wherein, air intake vent is opened in notebook computer one side, filter screen is opened and is located at the air intake vent place, air duct then is connected air intake vent, the air compressor fan is arranged in the air duct, after air enters air duct by air intake vent, promptly it is filtered, and see through the pressurization of air compressor fan, and the notebook computer internal pressure is kept greater than external pressure by filter screen, to avoid external dust to enter, in addition, air outlet then is opened in the relative position place of the connectivity port of notebook computer, in order to discharge air, when using the connectivity port, can stop that blocks dust sees through the connectivity port and enters notebook computer inside.

[embodiment]
Please refer to Figure 1A and Figure 1B, notebook computer dust-proof mechanism for first embodiment provided by the utility model, be to be applied on the notebook computer 10, it is by an air intake vent 100, a filter screen 110, an air duct 120, an air compressor fan 130, constituted with an air outlet 140.
Wherein, air intake vent 100 is main frame 20 front ends that are opened in notebook computer 10, and filter screen 110 is one to comprise the structure of screen frame 111 and the net heart 113, and it must cover air intake vent 100 with filtered air fully, so 110 of filter screens are located at air intake vent 100 places; 120 of air ducts are accepted from air intake vent 100 and towards main frame 20 inboard settings, in addition air compressor fan 130 are arranged in this air duct 120, so that the air outside suction is also pressurizeed; And air outlet 140 is the positions that are opened on the main frame 20 corresponding to connectivity port 30, can discharge for air.
When air compressor fan 130 suction extraneous airs, filter screen 110 can be earlier will be filtered out by the dust in air that air intake vent 100 enters air duct 120, and by the pressurization of air compressor fan 130, main frame 20 internal pressures are raise, with pressure in main frame 20 inner formation one, and can avoid external dust to enter main frame 20 inside.
In addition, air can be discharged from air outlet 140, when using connectivity port 30, then can provide avoid dust from the connectivity port 30 effects that enter main frame 20 inside.On the other hand, notebook computer dust-proof mechanism of the present utility model also can be assisted the heat radiation of main frame 20, and usefulness is upwards promoted.
In addition, notebook computer dust-proof mechanism of the present utility model more comprises a dust cap 150, this dust cap 150 can hide air outlet 140, and the one end is articulated on the main frame 20 of air outlet 140 1 sides, and dust cap 150 outsides also be provided with a projection 151 so that the user will cover or open.When the user does not use connectivity port 30, dust cap 150 can be covered, to follow the dustproof effect as protection.
For another shown in Figure 2, second specific embodiment provided by the utility model, consideration may lose its effect, therefore on the sidewall of air intake vent 200 behind a large amount of dust of filter screen 210 absorption, be provided with a depression 201, this depression 201 can be convenient to filter screen 210 is transferred to, and also correspondence is provided with a bullet spare 215 on the screen frame 211 of filter screen 210, not only can allow filter screen 210 push against in air intake vent 200, make filter screen 210 difficult drop-offs, more can filter screen 210 be pulled out to clean or to replace for staff.Also as shown in the figure, present embodiment has a patchhole 203 and insertion section 217 respectively in air intake vent 200 bottom sides and filter screen 210 bottoms, and insertion section 217 can be inserted in this patchhole 203, and makes filter screen 210 more fastening in air intake vent 200.
Moreover, in the present embodiment, air intake vent in groups, filter screen, air duct, can be adjusted with position, the quantity of air compressor fan.
As shown in Figure 3, the 3rd specific embodiment of the present utility model has promptly comprised two groups of air intake vents 300 and 400, filter screen 310 and 410, air duct 320 and 420 and air compressor fan 330 and 430 and one air outlet 340.Because of present embodiment utilizes two groups of dust-proof mechanisms,, improve dustproof effect so can strengthen thermolysis and keep the main frame internal pressure.
Simultaneously, the shape of air duct of the present utility model, size are not limited.
As shown in Figure 4, the 4th specific embodiment of the present utility model, its air duct 520 is the air duct length lengthenings that will be coffin originally, so, the not only strength of taking out by the air compressor fan, it can impel leaked-in air can be linked to be a gas, and has improved the flow rate flow of air, and strengthens its usefulness.
Perhaps, as shown in Figure 5, the 5th specific embodiment of the present utility model, its air duct 620 is designed near an end of air intake vent narrow, and the other end is then wide, according to white effort＜Bernoulli〉law, when air is flowed out toward a wide end by the narrow end of air duct, because the pressure step-down, the air mass flow of suction can strengthen, and strengthens dustproof effect.
Again, as shown in Figure 6, the 6th specific embodiment of the present utility model shows that air compressor fan 720 more can be a turbine fan, and bigger air mass flow can be provided, and the air intake vent 700 corresponding with it also can be located at main frame 20 bottom sides, to cooperate this turbine fan.
