The electronic device according to an embodiment of the present invention is shown in FIG. 1. The electronic device is, for example, a tablet computer or a mobile phone. A movable member 20 is disposed on the body 10 of the electronic device, and one side of the body 10 is disposed. There is a transparent partition 11 and, in addition, a plug 80 encloses a hole 15 in the body 10.

Please refer to Figures 1 and 2 together, and Figure 2 is a cross-sectional view taken along line x-x in Figure 1. The body 10 has an internal space 12 and a recess 13 for arranging various electronic components (not shown), and a hollow member 30 having a flexible material (for example, plastic) is received in the recess 13 The movable member 20 is connected inside, and the movable member 20 covers the groove 13 and substantially aligns with one surface 14 of the body 10 to maintain the appearance of the electronic device in a flat state. An air chamber 40 is formed in the hollow member 30 and located between the movable member 20 and the body 10. The air chamber 40 is connected to the internal space 12 via an air inlet passage 41, and is connected to the external environment via an exhaust passage 42. . In addition, an elastic member 50 surrounds the hollow member 30 and abuts the body 10 and the movable member 20, so that the movable member 20 is subjected to the upward elastic force of the elastic member 50. In this embodiment, the elastic member 50 can be a compression spring.

Next, please refer to FIG. 3, in the embodiment, the exhaust passage 42 A check valve 90 is provided, and the check valve 90 includes an elastic member 91 and a closing member 92, wherein the elastic member 91 abuts the closing member 92, so that the closing member 92 can isolate the air chamber 40 from the external environment. When the gas pressure in the gas chamber 40 (as indicated by the arrow A1) is greater than the elastic force of the elastic member 91 (as indicated by the arrow A2), the gas in the gas chamber 40 can be discharged to the external environment by the exhaust passage 42. Similarly, another check valve may be disposed inside the intake passage 41 so that the gas can flow only into the air chamber 40 from the internal space 12.

Please refer to Figures 1 and 4 again. A connecting pipe 60 is provided in the foregoing. The inner space 12 has a first end 61 and a second end 62, wherein the first end 61 is connected to the inner space 12 and the second end 62 is connected to the external environment. A slider 70 is disposed in the communication tube 60 and slidably adheres to the inner wall of the communication tube 60. In other words, the gas system located in the internal space 12 cannot be discharged to the external environment via the communication pipe 60. Further, the communication tube 60 has a transparent tube wall adjacent to the transparent partition 11 shown in Fig. 1 so that the user can observe the pressure change of the internal space 12 from the outside.

It should be understood that the hole 15 can communicate with the internal space 12 of the body 10. Unlike the external environment, when the plug 80 closes the hole 15, the gas in the internal space 12 cannot flow out to the external environment via the hole 15.

Next, please refer to Figure 5, when the movable member 20 is subjected to an external force (such as When the arrow is shown) and is displaced from the first position shown in FIG. 2 to the second position shown in FIG. 5, the gas in the gas chamber 40 is discharged through the exhaust passage 42; then, when the applied force is released Thereafter, the movable member 20 will be subjected to the elastic force of the elastic member 50 to return to the first position from the second position, at which time the gas in the internal space 12 enters the air chamber 40 via the intake passage 41. After repeating the above actions, the internal space 12 The gas pressure will be significantly less than the gas pressure of the external environment. As such, referring to FIG. 6, the slider 70 in the communication tube 60 will move toward the first end 61 of the communication tube 60, thereby determining that the internal space 12 of the electronic device is in a sealed state to ensure that the electronic device can be It has the effect of waterproofing. If the displacement of the slider 70 is still not generated after the above operation, it can be judged that there is a gap between the internal space 12 and the external environment, and there is no waterproof effect.

When the slider 70 is displaced toward the first end 61 of the communication tube 60, use After confirming that the electronic device has waterproof effect, if it is necessary to detect again, the plug body 80 shown in FIG. 1 can be removed from the hole 15 so that the external environment gas enters the internal space 12 through the hole 15, and the sliding member 70 can be Returning to the initial position shown in Fig. 5, and then closing the hole 15 again, the detection can be performed again.

As shown in FIG. 7, in another embodiment of the present invention, the movable member 20 There is a protruding ring 21, and the ring 21 is fitted to the side wall of the hollow member 30 and is slidable along the side wall of the hollow member 30. In addition, as shown in FIG. 8 , in another embodiment, the air chamber 40 may be directly formed between the movable member 20 and the body 10 , wherein the movable member 20 is disposed in the recess 13 and is opposite to the body 10 . move up and down.

In summary, the present invention provides an electronic device that is advantageous for The user detects the sealing condition of the electronic device to determine whether it has a waterproof effect.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention. Those skilled in the art having the ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
