The following detailed description will further illustrate the invention in conjunction with the above-described figures.
Detailed Description
A waterproof device is used for an opening such as an air hole or a sound hole in an electronic apparatus to prevent water.
Referring to fig. 1, a waterproof device includes a housing 10 and a floating plate 20. The housing 10 may be composed of an upper cover 110, a lower cover 120 and side walls, a cavity is formed inside the housing 10, and the upper cover 110 and the lower cover 120 of the housing 10 are respectively provided with openings, for example, the openings include a plurality of first openings 1101 provided on the upper cover and a plurality of second openings 1201 provided on the lower cover. The floating plate 20 is floatingly disposed in the chamber of the housing 10 and divides the chamber into upper and lower portions.
Wherein, the floating plate 20 is provided with a plurality of through holes 210, and the upper cover 110 is provided with a plug body 30 matched with the through holes 210.
Referring to fig. 1 and 2, in use, if the floating plate 20 is not in contact with water, the floating plate 20 sinks under its own weight, and the first opening 1101 of the upper cover 110 and the second opening 1201 of the lower cover 120 are communicated through the through hole 210 of the floating plate 20 to form a channel that can be used as an air hole, a sound hole, etc., and the channel can be kept normally open. When water is met, the floating plate 20 floats upwards, the through hole 210 on the floating plate moves upwards to be jointed with the plug body 30 and is sealed by the plug body 30, the first opening 1101 of the upper cover 110 and the second opening 1201 of the lower cover 120 are separated by the floating plate 20, an active waterproof effect can be achieved, and further the electrical safety of related electronic equipment applying the waterproof device can be guaranteed.
To ensure the sealing property when the plug 30 is engaged with the through-hole 210, the plug 30 may be made of an elastic material such as rubber.
As a preferred embodiment, the floating plate 20 may be provided as a hollow structure to increase its buoyancy when it encounters water, thereby improving the sensitivity of waterproofing.
In a preferred embodiment, a stop (not shown) is provided in the housing 10 for limiting the resting position of the floating plate 20 when the floating plate 20 sinks, so as to prevent the floating plate 20 from sinking to be attached to the lower cover 120 and close the second opening of the lower cover 120. For example, in a specific implementation, the stopper may be a baffle fixed on the inner wall of the housing 10 and located at the lower portion of the floating plate 20, and the floating plate 20 is stopped by the baffle when it sinks to be limited to the resting position.
In order to limit the resting position of the floating plate 20 during sinking, in a specific embodiment, a support leg (not shown) may be provided at the lower portion of the floating plate 20.
In another preferred embodiment, the side surface of the floating plate 20 is provided with a side plate 220 contacting with the inner wall of the housing 10, and the side plate 220 can be used for guiding the floating plate 20 when floating up and sinking down, so as to ensure that the through hole 210 on the floating plate 20 can be accurately abutted against the plug body 30 when floating up, and simultaneously, the through hole 210 on the floating plate 20 can be smoothly separated from the plug body 30 when sinking down.
Preferably, the slide groove 101 may be provided at a portion where the side wall of the side wall housing 10 contacts the side plate 220, and the protruding end 2210 corresponding to the slide groove 101 may be provided on the outer side of the side plate 220. When the floating plate 20 sinks, the protruding end 2210 contacts with the lower part of the sliding groove 101 to limit the resting position of the floating plate 20, and simultaneously, the protruding end 2210 can slide along the sliding groove 101 to play a guiding role in the floating and sinking of the floating plate 20.
Further, the lower portion of the side plate 220 may further extend to form a support portion 2201 to limit the resting position of the floating plate 20 when sinking.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
