It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

As shown in fig. 1 to 6, according to an embodiment of the present disclosure, there is provided an electronic apparatus having a superior waterproof effect. The electronic equipment can be a mobile phone, a tablet personal computer, a notebook computer, a palm computer, an intelligent bracelet, an intelligent watch and the like.

Specifically, the electronic apparatus includes a housing 1, a liquid detection device 2, and a waterproof assembly 3. The interior of the housing 1 has a receiving chamber 11. The main board of the electronic device is disposed in the accommodation chamber 11, protected by the housing 1. The liquid detection device 2 is used for detecting whether the electronic equipment is in a water contact state, wherein the water contact state means that the electronic equipment falls into liquid and the electronic equipment is completely contacted with the liquid; it may also mean that the liquid is sprinkled on the electronic equipment, and the electronic equipment is partially in contact with the liquid, as long as there is a risk that the liquid enters the accommodating chamber 11 from the housing 1 to damage the main board, i.e. the electronic equipment is in a water-touching state.

As shown in fig. 3 and 4, the housing 1 is provided with a through-hole 12, and the through-hole 12 communicates the outside of the housing 1 with the housing chamber 11. The through-hole 12 is a general term for only an opening communicating the outside of the housing 1 with the accommodating chamber 11, and the type and size of the opening are different, and the function to be achieved is also different.

Optionally, the through hole 12 is an MIC hole, an earphone hole, a Micro USB socket, a Type-C socket, or a Lightning interface. The MIC hole is the trompil of inserting the microphone, and the earphone hole is the trompil of inserting the earphone, and Micro USB socket, Type-C socket and Lightning interface are the trompil of inserting the data line. Because microphone, earphone, data line etc. all need be connected through corresponding trompil and the mainboard that is located and hold chamber 11 electricity, this has led to electronic equipment to touch when water, and liquid very easily gets into from the trompil and holds chamber 11 in, and then damages the mainboard. And this application can avoid liquid to get into the inside that holds chamber 11 by casing 1 effectively through carrying out the shutoff to corresponding through hole 12 in the inside that holds chamber 11, and then damages the mainboard. This electronic equipment is when touching water, the through hole 12 homoenergetic of a plurality of types can be by the shutoff, and the chamber 11 that holds that makes forms a totally enclosed cavity, and liquid can't get into through the trompil of casing 1 and hold in the chamber 11 to prevented effectively that the phenomenon that liquid contact mainboard damaged the mainboard from taking place, water-proof effects is better.

As shown in fig. 2 and 5, a mounting groove 13 is provided on an outer side wall of the housing 1, and the liquid detection device 2 is disposed in the mounting groove 13. The mounting groove 13 is used for mounting the liquid detection device 2. The mounting groove 13 is communicated with the outside of the housing 1, while the mounting groove 13 is not communicated with the accommodating chamber 11, and liquid outside the housing 1 cannot enter the accommodating chamber 11 through the mounting groove 13. Since the mounting groove 13 communicates with the outside of the housing 1, when the electronic device is exposed to water, liquid directly enters the mounting groove 13.

The driving device 31 may have other driving structures, such as an air cylinder, a hydraulic cylinder, etc., as long as the waterproof member 32 can be driven to move by the driving device 31, and the present invention is not limited thereto.

Optionally, the waterproof member 32 is a flexible pad, and the flexible pad can deform, so that the waterproof member 32 can tightly close the through hole 12 under the driving of the driving device 31, and the waterproof effect is good. The flexible pad is driven by the driving device 31 to move in a direction close to the through hole 12, and finally the flexible pad covers the through hole 12 to block the through hole 12. Because the flexible pad moves along a straight line, the movement mode is simpler, and the driving device 31 is convenient to drive the flexible pad.

Further optionally, the area of the flexible mat is larger than the cross-sectional area of the through-going hole 12 in a direction perpendicular to the axial direction. This makes the flexible pad can carry out the shutoff well to through hole 12, and water-proof effects is better. The flexible pad may be a cylinder or a cuboid, as long as the waterproof hole can be plugged, which is not limited in the present invention. Preferably, the flexible pad may be a cylinder, and because the corners of the flexible pad are less, the flexible pad will disturb less other components in the accommodating chamber 11 during the moving process, so as to optimize the arrangement of each component in the accommodating chamber 11.

In this embodiment, when the liquid detection device 2 detects that liquid enters the mounting groove 13, the driving device 31 drives the waterproof member 32 to close the through hole 12.

In case of liquid entering into the mounting groove 13, the electronic device is in a water contact state, and the driving device 31 drives the waterproof member 32 to move and block the through hole 12, thereby effectively preventing the liquid from entering the inside of the electronic device through the through hole to damage the electronic device.
