Title:
VALVE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/065148
Kind Code:
A1
Abstract:
A valve and an electronic device. The electronic device comprises a housing, and an electronic component is disposed in the housing; the valve is disposed on the housing. The valve comprises: a valve body, the valve body being provided with a channel, and the channel being communicated with the inner side and the outer side of the housing in which the valve body is mounted; and a stopper, the stopper being disposed on the valve body, and used for closing the channel, and when a pressure difference between the inner side and the outer side is greater than a threshold, the stopper opening the channel. In this way, when the pressure difference between the inner side and the outer side is small, the channel is closed by means of the stopper, thereby avoiding water vapor on the outer side from entering the inner side. Meanwhile, the stopper can open the channel when the pressure difference between the inner side and the outer side is greater than the threshold, so as to balance the pressure difference between the inner side and the outer side, and avoid an adverse effect caused by an excessive pressure difference between the inner side and the outer side, and when the pressure difference between the inner side and the outer side is reduced below the threshold, the stopper closes the channel, so as to prevent water vapor on the outer side from entering the inner side. Therefore, the content of water vapor on the inner side is reduced, the possibility of condensation is reduced, and the influence of water vapor and condensation on the electronic component is reduced.
