[0032] Please refer to the accompanying drawings Figure 1 , which shows a partial schematic view of the cover 11 of the electronic device to which the liquid-blocking structure according to an embodiment of the present invention is applied.

[0033] The electronic device mentioned herein is, for example, a notebook computer, and its cover 11 can correspond to a keyboard frame member, that is, the cover 11 is the so-called "C-piece" in the field of notebook computers. As Figure 1 shown, one side of the cover 11 may have a sound outlet hole array 11sh. The accompanying drawings Figure 1 are only partial schematics, and it should be understood that the other opposite side of the cover 11 may also have a sound outlet hole array 11sh to form a symmetric sound outlet setting. Continuing from the above, the electronic device is, for example, a notebook computer, and the sound outlet hole array 11sh is the so-called speaker sound outlet hole. In view of the background technology, the speaker sound outlet holes of notebook computers are likely to be infiltrated by liquid (such as water), resulting in damage to the internal electronic components of the device. Now, a liquid-blocking structure that can improve this problem will be described hereinafter.

[0034] Please also refer to the accompanying drawings Figures 2A - 2B , Figure 2A which shows an exploded assembly view of the liquid-blocking structure 100 and the cover 11 according to an embodiment, and Figure 2B which shows a schematic view of the structural body 110 of the liquid-blocking structure 100.

[0035] The liquid-blocking structure 100 is applicable to an electronic device to prevent the liquid flowing in from the sound outlet hole array 11sh from penetrating into the interior of the electronic device and causing damage. As Figure 2A shown, the liquid-blocking structure 100 may include a structural body 110 and a gasket 120. The structural body 110 is arranged corresponding to the sound outlet hole array 11sh. Figure 2A Shown is from Figure 1The rear view of the cover body 11, that is, the liquid-blocking structure 100 is disposed below the sound outlet hole array 11sh, and its structural main body 110 and the gasket 120 are longitudinally stacked with the cover body 11 of the electronic device. The structural main body 110 can cover the range of the sound outlet hole array 11sh to ensure that the liquid flowing in from any local position of the sound outlet hole array 11sh can be blocked. The gasket 120 is disposed between the cover body 11 and the structural main body 110. The gasket 120 is, for example, a non-woven fabric, which can be made of Mylar material. The gasket 120 is laid under the sound outlet hole array 11sh to block the liquid-blocking structure 100, so that the liquid-blocking structure 100 is not visible on the appearance of the electronic device, providing an aesthetic function.

[0036] As Figure 2B shown, the structural main body 110 can include a drainage channel 111 and a liquid collecting tank 112. Both the drainage channel 111 and the liquid collecting tank 112 correspond to the position below the sound outlet hole array 11sh. When the liquid flows in from the sound outlet hole array 11sh, the drainage channel 111 can be used to receive the liquid and guide the liquid to the liquid collecting tank 112. The drainage channel 111 can be a flow-aiding design that is slightly inclined to the horizontal plane to accelerate the guiding of the liquid to the liquid collecting tank 112. A drainage pipe LT can be provided in the liquid collecting tank 112. When the liquid accumulates in the liquid collecting tank 112 to a critical height, the drainage pipe LT can use its through port LT-h to discharge part of the liquid from the outlet 112ex out of the liquid collecting tank 112, that is, the drainage pipe LT can be open-connected to the outside of the electronic device.

[0037] As Figure 2B shown, in the extending direction of the structural main body 110, the length L111 of the drainage channel 111 is greater than the length L112 of the liquid collecting tank 112. The liquid collecting tank 112 can have an inclined surface b, and the inclined surface b is located at the connection between the liquid collecting tank 112 and the drainage channel 111. When the liquid is guided to the liquid collecting tank 112 through the drainage channel 111, the inclined surface b can help the liquid flow into the liquid collecting tank 112 and prevent the liquid from flowing back to the drainage channel 111. In Figures 2A - 2B the shown embodiment, the structural main body 110 of the liquid-blocking structure 100 and the cover body 11 of the electronic device have corresponding fixing holes sh, so that the structural main body 110 can be fixed to the cover body 11 by locking. Specifically, for example, a screw member can be used to lock the fixing holes sh of the structural main body 110 and the cover body 11 at the same time to fix the structural main body 110 and the cover body 11. Corresponding to the fixation of the structural main body 110 and the cover body 11, the gasket 120 can be clamped between the structural main body 110 and the cover body 11.

[0038] In Figures 2A - 2BIn the illustrated embodiment, since the structural main body 110 and the cover 11 are locked and fixed on both sides, the middle part of the structural main body 110 does not need to be locked and fixed to the base (not shown) of the electronic device. The base of the electronic device is a component assembled with the cover 11, that is, the base is the so-called "D-piece" in the field of laptop computers. If the middle part of the structural main body 110 is further locked and fixed to the base of the electronic device, the middle part of the structural main body 110 will be pulled up and down by the cover 11 and the base, which may easily cause liquid to leak from the drainage channel 111 or even cause the structural main body 110 to be deformed, affecting the liquid blocking effect.

[0039] Please further refer to the accompanying drawings Figures 3A - 3B , Figure 3A The following shows an exploded view of the assembly of the liquid blocking structure 200 and the cover 11 according to another embodiment, and Figure 3B The following shows Figure 3A A schematic diagram of the structural main body 210 of the liquid blocking structure 200 shown.

[0040] The liquid blocking structure 200 is applicable to an electronic device to prevent liquid flowing in from the sound outlet hole array 11sh from penetrating into the interior of the electronic device and causing damage. As Figure 3A shown, the liquid blocking structure 200 may include a structural main body 210 and a gasket 220. The structural main body 210 is arranged corresponding to the sound outlet hole array 11sh. Figure 3A The following shows from Figure 1 the back view of the cover 11, that is, the liquid blocking structure 200 is arranged below the sound outlet hole array 11sh, and its structural main body 210 and gasket 220 are longitudinally stacked with the cover 11 of the electronic device. The structural main body 210 can cover the range of the sound outlet hole array 11sh to ensure that liquid flowing in from any local position of the sound outlet hole array 11sh can be blocked. The gasket 220 is arranged between the cover 11 and the structural main body 210. The gasket 220 is, for example, non-woven fabric, which can be made of mylar material. The gasket 220 is laid under the sound outlet hole array 11sh to cover the liquid blocking structure 200, making the liquid blocking structure 200 invisible on the appearance of the electronic device, providing an aesthetic function.

[0041] As Figure 3BAs shown, the structural body 210 may include a liquid drainage channel 211 and a liquid collection tank 212. Both the liquid drainage channel 211 and the liquid collection tank 212 are correspondingly below the sound outlet hole array 11sh. When liquid flows in from the sound outlet hole array 11sh, the liquid drainage channel 211 can be used to receive the liquid and guide the liquid to flow to the liquid collection tank 212. The liquid drainage channel 211 can be a flow-assisting design slightly inclined to the horizontal plane to accelerate guiding the liquid to flow to the liquid collection tank 212. Similarly, a liquid discharge pipe LT can be provided in the liquid collection tank 212. When the liquid accumulates in the liquid collection tank 212 to a critical height, the liquid discharge pipe LT can use its through port LT-h to discharge part of the liquid from the outlet 212ex out of the liquid collection tank 212, that is, the liquid discharge pipe LT can be openly connected to the outside of the electronic device.

[0042] As Figure 3B shown, in the extending direction of the structural body 210, the length L211 of the liquid drainage channel 211 is greater than the length L212 of the liquid collection tank 212. The liquid collection tank 212 can have an inclined surface b, and the inclined surface b is located at the connection between the liquid collection tank 212 and the liquid drainage channel 211. When the liquid is guided to the liquid collection tank 212 through the liquid drainage channel 211, the inclined surface b can assist the liquid to flow into the liquid collection tank 212 and prevent the liquid from flowing back to the liquid drainage channel 211. The structural body 210 can have an annular area 210sr, and the liquid drainage channel 211 and the gasket 220 can be located within the range surrounded by the annular area 210sr. In Figures 3A - 3B the shown embodiment, the structural body 210 of the liquid-blocking structure 200 can be fixed to the cover body 11 by means of an adhesive disposed in the annular area 210sr. Specifically, the liquid-blocking structure 200 can coat or attach a frame adhesive in the annular area 210sr to be fixed to the cover body 11, and the gasket 220 can be clamped between the structural body 210 and the cover body 11. Due to the inward pushing arrangement of the annular area 210sr, it can be understood that the size of the gasket 220 is smaller than that of the gasket 120 in the previous embodiment.

[0043] In Figures 3A - 3B the shown embodiment, since the structural body 210 is adhesively fixed to the cover body 11 throughout by the adhesive in the annular area 210sr, the middle part of the structural body 210 is suitable for being fixed to the base of the electronic device (not shown, that is, the so-called "D part" in the field of laptop computers), and it is not easy to cause the situation that the middle part of the structural body 210 is pulled up and down by the cover body 11 and the base, resulting in liquid leakage from the liquid drainage channel 211 or even deformation of the structural body 210.

[0044] Please refer to the attached drawings Figure 4 which shows Figure 2B and 3B a cross-sectional view of the liquid discharge pipe LT commonly included in the structural bodies 110 and 210 shown.

[0045] As Figure 4As shown, the liquid discharge pipe LT includes a connected first pipe section T1 and a second pipe section T2. In a sectional view, the first pipe section T1 and the second pipe section T2 present an inverted U-shaped structure, and the extended length LT1 of the first pipe section T1 is less than the extended length LT2 of the second pipe section T2. When the liquid flows to the liquid collecting tank 112 (or the liquid collecting tank 212), since the through port LT-h of the liquid discharge pipe LT connects the first pipe section T1 and the liquid collecting tank 112 (or the liquid collecting tank 212), part of the liquid can flow into the first pipe section T1 through the through port LT-h and be contained in the first pipe section T1 at a liquid level. At this time, based on the principle of communicating vessels, the liquid level in the first pipe section T1 will be equal to the liquid level in the liquid collecting tank 112 (or the liquid collecting tank 212). As the liquid accumulated in the liquid collecting tank 112 (or the liquid collecting tank 212) gradually increases, the liquid level in the first pipe section T1 also gradually rises. When the liquid level in the first pipe section T1 is higher than the critical height H, this part of the liquid will enter the second pipe section T2, then flow through the second pipe section T2 and be discharged from the outlet 112ex (or the outlet 212ex) of the liquid collecting tank 112 (or the liquid collecting tank 212).

[0046] In summary, for the liquid blocking structure applicable to an electronic device proposed in the embodiment of the present invention, its structural main body is provided with a drainage channel and a liquid collecting tank, and the liquid flowing into the sound outlet hole array of the electronic device can be received by the drainage channel and collected in the liquid collecting tank to prevent the liquid from penetrating into the electronic device from the open sound outlet hole array. Even, the liquid collected can be discharged from the liquid collecting tank through the arrangement of the liquid discharge pipe contained in the liquid collecting tank. Thereby, the effect of avoiding damage to the internal electronic components can be achieved.

Those with ordinary knowledge in the technical field to which the present invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention.
