CN2567921Y - Water-proof device for electronic appliance - Google Patents

Abstract

The utility model relates to a waterproof device for an electronic appliance, which is a soft bag arranged in an electronic appliance and utilizes a working principle that pressure difference is zero to solve the waterproof problem of the electronic appliance. The utility model has the advantages of simple structure, low cost and good waterproof effect.

Description

Electronics commodity water-tight device

Technical field

The utility model relates to the water-tight device of electronics commodity.

Background technology

At present, the waterproof of existing electronics commodity mostly adopts the method for various sealings.As mobile phone, electronic thermometer etc., its waterproof is exactly with sealing joint, uses the gum cover package button, to reach these electronics commodity back purpose that can advance nowhere of water that falls into the water.But, between each knob, interface of front and rear covers, battery bonnet etc., the space will appear under certain hydraulic pressure, thereby cause leaking, damage electronic component, knob was lost efficacy because of leaking, electronics commodity function total loss or part are lost, and go such as nothing demonstration, stored contents damage etc.And this water-proofing treatment has improved production cost of products and production difficulty, has reduced product percent of pass, can't guarantee the waterproof ability of electronics commodity such as mobile phone, electronic thermometer.

Summary of the invention

The purpose of this utility model is: a kind of electronics commodity inside that is arranged at is provided, and utilizing pressure differential is the device that zero principle solves electronics commodity waterproof.

Technology contents mainly is: it is the software capsule band which is provided with a limbers.Material can adopt rubber also to can be flexible impermeable materials such as plastics.When producing the electronics commodity, this device is installed on internal body, is establishing the installation that closely cooperates of limbers on an aperture and the software capsule bag on the plate behind the casing.When electronics commodity such as mobile phone were fallen in the water because of carelessness, just water flows into software capsule bag from cell phone rear cover aperture that is place, this water-tight device limbers, software capsule bag opened along with the inflow of water, pushes the air in the mobile phone simultaneously.Because air quality is certain in the casing, atmospheric pressure will be increased than original, outside atmospheric pressure in reaching casing and the casing during pressure equilibrium of water, realize " zero pressure difference ", thereby water can't flow into from the slit of electronics commodity, reaches the waterproof purpose, equally after mobile phone is pulled out from water, pressure is greater than external pressure in the machine, and water flows out from the capsule bag.

Advantage of the present utility model is: 1. simple in structure, production cost is low; 2. good water-proof effect.

Embodiment

Can adopt the materials that flexibility is good, water resistance is strong such as rubber or plastics to make the software capsule bag 2 which is provided with a limbers 1.

Claims (1)

1. electronics commodity water-tight device, it is characterized in that: it is the software capsule bag [2] which is provided with a limbers [1].
