Electronic device and control method

Abstract

The invention relates to an electronic device. The electronic device comprises a shell, a boosting device, a humidity sensor and a control device, wherein the shell comprises an inner cavity, and theboosting device, the humidity sensor and the control device are all fixed in the inner cavity; the shell is at least provided with an opening communicated with the inner cavity, and the humidity sensor is arranged corresponding to the opening; the control device is electrically connected with the boosting device and the humidity sensor, is configured to control the boosting device to inflate and boost the inner cavity when the humidity sensor monitors that the humidity of the opening exceeds a preset humidity threshold value, so that the pressure of the inner cavity is enabled to be higher than the external water vapor pressure, and water vapor is prevented from entering the inner cavity to damage the electronic device. According to the electronic device, waterproofing is achieved in an active boosting mode, the assembly, disassembly and maintenance are relatively convenient, and meanwhile, the reliability requirement for long-term use is met. The invention further relates to a controlmethod of the electronic device.

Description

technical field [0001] The present application relates to the field of electronic devices, in particular to a waterproof electronic device and a control method for the electronic device. Background technique [0002] Electronic devices need to have a certain degree of waterproof and moisture-proof capability, and most of the electronic devices represented by mobile phones on the market currently have low waterproof performance due to cost considerations. Only special rugged mobile phones or high-end flagship phones will be equipped with IP68 level of protection. This is because the waterproof structure usually requires special sealing of the interface in the electronic device through glue. For example, the earphone and USB interface need to be matched by dispensing and extruding the sealing rubber sleeve, or the side buttons need to be set for special cooperation. Silicone extrusion seal etc. As for the casing, panel, etc. of the electronic device, it generally needs to be...

Problems solved by technology

[0003] Furthermore, after the assembly of the electronic device is completed, a sealing test is required, and this series of measures will lead to a pass-through rate of the electronic device generally lower than 80%.

Moreover, the extensive use of glue will increase the cost of dismantling and maintenance of electronic devices, making rework extremely difficult

In addition, during the daily use of electronic devices by users, there may be phenomena such as dropping the electronic device from the outside world, and the aging of the internal components of the electronic device after long-term use, which will also affect the long-term reliability of the electronic device. performance, especially the reliability of the waterproof design
