Description of the new type: [Technical field to which the new type belongs] This creation relates to a dust-proof mechanism, especially a dust-proof mechanism for a notebook computer. [Previous technology] With the continuous advancement of science and technology, 'the various types of electronic equipment currently being developed are also being refined.' However, they are also more tolerant of dust intrusion and affect the effectiveness of important internal components, and even cause machines. malfunction. 7 Under normal circumstances, the ash degree of the air towel is lower than 3Qmg / m3, but for a laptop computer, if dust-air enters the inside of its host computer with the air, it may cause money. Especially in special environments such as online polluters, Yang volcanoes, and prostitutes, there is an urgent need for effective dust protection institutions. For example, industrial notebook computers must be used in a dusty environment because of the special environment. When the ports are used, dust can easily enter the host computer and damage the host computer. However, in the previous design, the cover was used to directly hold the Laibu donkey, so in a dusty environment, most of the ports could not be made, which was convenient for users. [New content]; Read the question first, this creation proposes a kind of dust-proof mechanism for notebook computers, which uses the principle of pressure difference to keep the internal pressure of the notebook computer host's pressure greater than the axial force 'to achieve dust-proof W. At this time, the dust will not be known into the pen, and the user's internal use will be more convenient. M274558 The dust-proof mechanism of the notebook computer provided by this creation includes air inlets, filters, air compression fans, air channels and air outlets. The towel opening is set on the side of the notebook computer, and the Yizhang is set at the air outlet. The air channel is connected to the air outlet. The air compression fan is installed in the air channel. After the air enters the Wei channel from the air outlet, it is filtered by a filter and pressurized by the air compression fan to make the notebook computer. The internal pressure is kept greater than the external pressure to prevent external dust from entering. In addition, the air outlet is set at the relative position of the connection 珲 of the laptop to exhaust air. ^ Use the connection 槔 sun guard to block and prevent dust from passing through the connection. Port into the laptop. Regarding the features and implementation of this creation, Langju—Better Practice_ with the illustrations in detail is as follows: [Embodiment], please refer to “1A and 1B” notes for the first embodiment provided by this creation The type computer dustproof mechanism is made on the notebook computer 1 (), which is composed of an air inlet 100, a filter 110, an air passage m, an air compression fan i plus, and an air outlet 140. Among them, the air inlet Π⑽ is installed at the front end of the host computer 20 of the notebook computer 1G, and the filter 110 is a structure including a network frame η and a network core 113. It must completely cover the air inlet 100 to filter and air, so The filter m is installed at the air inlet ⑽; the air channel 120 is connected to the wind and the air is installed toward the inside of the host 2Q, and an air compression fan 13G is set in this air channel m to draw in the external air. And pressurize; and the air outlet 14G is opened on the host 2G corresponding to the M274558 position of the connection ^ for air exhaust. When the air compression fan 130 draws in the outside air, according to the network, the air will first pass the dust in the air entering the air channel 12 by the air inlet, and the host 20 will be pressurized by the air compression fan 130. The internal pressure is raised to form an internal pressure inside the host 20, and external dust can be prevented from entering the host 20. In addition, the air can be discharged from the air outlet 14o, and when the port 刈 is used, the effect of preventing dust from entering the host 20 through the port 30 can be provided. On the other hand, the notebook-type dust and electric mechanism of this creation can also cooperate with the heat dissipation of the social machine 2 () to improve the efficiency. '' In addition, the dustproof mechanism of the notebook computer of this creation further includes a dustproof cover, this dustproof cover 150 can cover the air outlet 0 140, and one end thereof is pivotally connected to the host 20 on the side of the air outlet 1440, and the dustproof cover 15 〇There is also a convex block 151 on the outer side to facilitate the user to cover or inspect it. When the user does not use the port 3G, the dust cover 150 can be covered 'for protection and dust prevention. In addition, as shown in FIG. 2, the second embodiment provided by this creation considers that a large amount of ash buttons are adsorbed on the filter screen 210 and may lose its efficacy. Therefore, a recess is provided on the side wall of the air inlet 200. 201, this recess 2001 can be used to easily pull out the filter, and an elastic member 215 is correspondingly provided on the screen frame 211 of the filter 21, not only can the filter 210 be pressed against the air inlet 200. In this way, it is difficult for the filter screen 21 to fall off, and the filter screen 210 can be pulled out by humans for cleaning or replacement. As shown in the figure, this embodiment has an insertion hole 203 and an insertion portion 217 on the bottom side of the air inlet 200 and the bottom end of the filter 21, respectively. The insertion portion 217 can be inserted into the insertion hole 203. The strainer 21 is tightened in the inlet M274558 200. Furthermore, in this example, the position and number of the group of air inlets, grate nets, air channels, and air compression fans can be adjusted. As shown in FIG. 3, the third embodiment of the present invention includes two sets of air inlets 300 and 400, filters 31 and 41, air channels 32 and 42, and air compression fans 330 and 430. '和 _ 出 风口 34 (). Because this embodiment uses two sets of dust prevention mechanisms, the heat dissipation effect and the internal pressure of the main engine can be enhanced, and the dust prevention effect can be improved. The shape and size of the air passages of the same h ’original creation are not limited. As shown in Figure 4, the fourth embodiment of the present invention has an air passage 52 that lengthens the length of the air passage that was originally a rectangular space. In this way, it is not only the air compression fan that is capable of stimulating the flow of people. It can connect to air, which increases the velocity and flow of air and enhances its efficiency. Or 'as shown in item 5', the fifth specific embodiment of this creation, the air channel 6205 of which is counted as one of the sinus near the air inlet is narrow at one end and wide at the other end, according to Bai Dili's "Bernoulli" law 'when borrowed From the line pressure Lai Niu to flow from the narrow end of the air channel to the wide-end 由于 'Because the pressure becomes lower, the flow of pumped air will increase, and the dustproof effect will be enhanced. Also as shown in Section 6 ®, the sixth specific supplement of this creation shows that the air compression fan 720 can be a turbo-fan, which can provide greater air flow, and the corresponding air inlet 7GG can also be set on the host. 2G bottom side to match this turbo fan /. The above are only the preferred embodiments of this creation, and are not intended to limit the scope of implementation of this creation; that is, all equal M274558 changes and modifications made in accordance with the scope of the patent application for this creation are the creation patents Covered.
