Abstract

Provided is a waterproof decompression valve used for a mobile phone. The waterproof decompression valve is mainly used in the mobile phone. The mobile phone decompression valve tightly combines with a mobile phone housing, and prevents water from entering the mobile phone through the decompression valve, thereby preferably protecting the mobile phone. At present, the mobile phone does not has a function of decompression valve, so when ambient pressure changes, such as from a high altitude place to a low altitude place, or from the low altitude place to the high altitude place, a sound production membrane of a horn of the mobile phone would not work since a sealing function of the mobile phone is good. A most important characteristic of the decompression valve is that a pressure balance hole is disposed on the mobile phone housing, a waterproof membrane is disposed outside the hole, and the waterproof membrane is covered with foam. Air can get through the waterproof membrane, but water cannot get through the waterproof membrane, and thus pressure balance is realized in and out of the mobile, and meanwhile water is prevented from entering the mobile phone. The mobile phone with the technology can adapt to ambient pressure changes. In areas of different altitudes, normal communication by the mobile phone can be ensured.

Description

A kind of mobile phone waterproof relief valve

Technical field

The utility model relates to a kind of waterproof relief valve, mainly is to be used on the mobile phone, realizes the pressure balance that mobile phone is inside and outside, and anti-sealing enters mobile phone inside by relief valve simultaneously.

Background technology

At present mobile phone does not have the relief valve function, when mobile phone when ambient pressure changes, as place low from the height above sea level to height above sea level, perhaps from the low place to height above sea level of height above sea level, because the sealing function of mobile phone is very strong, may cause the sounding film cisco unity malfunction of loudspeaker.

Summary of the invention

The purpose of this utility model provides a kind of waterproof relief valve, mainly is to be used on the mobile phone, the pressure that the balance mobile phone is inside and outside, and the mobile phone inside trumpet can operate as normal under the situation of different regions, differing heights to realize mobile phone.Anti-sealing enters mobile phone inside by relief valve simultaneously.

The utility model is achieved in that the waterproof relief valve is made up of the relief hole (3) on foam (1), waterproof membrane (2) and the phone housing (4).Foam (1) is pressed in the top of waterproof membrane (2) and is bonded together with marine glue, waterproof membrane (2) is bonded on the end face of foam (1), the assembly of foam (1) and waterproof membrane (2) is contained on the relief hole (3) on the phone housing (4), glue (5) is evenly put in waterproof membrane assembly side, is bonded together with phone housing (4).

The diameter of the relief hole (3) on the phone housing (4) is that this through hole is the air pressure of balance outer handset and mobile phone inside between 1.2 millimeters through holes to 1.5 mm dias.For anti-sealing enters into mobile phone inside by relief hole (3), adopted waterproof membrane (2) to cover outer side plane at aperture.For fixing waterproof membrane (2) better, prevent that extraneous sharp object from puncturing or fall, and adopted foam (1) to be pressed in the outside of waterproof membrane (2).Be through hole in the middle of the foam (1), be convenient to air and pass through.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model assembling schematic diagram.

Fig. 3 is the utility model structure cutaway view.

Embodiment:

Now by reference to the accompanying drawings the utility model is described in further detail.

The utility model is made up of the relief hole (3) on foam (1), waterproof membrane (2) and the phone housing (4).At first at the design phone housing when (4), one designed when one design relief hole (3) on shell, this relief hole (3) can pass through the mould design of phone housing (4), and finished by injection moulding.It is the not water flowing of ventilating that the material of waterproof membrane (2) is selected, and does circular.Foam (1) is toroidal, and excircle is pushed down the excircle of waterproof membrane (2), and the endoporus of foam (1) is greater than the internal diameter of relief hole (3), so that can be unobstructedly through foam (1) by the air of relief hole (3).

During production, with glue waterproof membrane (2) is bonded at the end face of foam (1), and then with circumferential point glue (5) with foam (1) and waterproof membrane (2) assembly, be bonded on the counter bore side of phone housing (4).

Claims

1. mobile phone waterproof relief valve, it is characterized in that, formed by the relief hole (3) on foam (1), waterproof membrane (2) and the phone housing (4), foam (1) is pressed in the top of waterproof membrane (2) and is bonded together with marine glue, waterproof membrane (2) is bonded on the end face of foam (1), the assembly of foam (1) and waterproof membrane (2) is contained on the relief hole (3) on the phone housing (4), and glue (5) is evenly put in waterproof membrane assembly side, is bonded together with phone housing (4).

2. waterproof relief valve as claimed in claim 1 is characterized in that, relief hole (3) is opened on phone housing (4), between 1.2 millimeters to 1.5 millimeters of its diameter ranges.

3. waterproof relief valve as claimed in claim 1 is characterized in that, waterproof membrane (2) covers relief hole (3).

4. waterproof relief valve as claimed in claim 1 is characterized in that, the external diameter of foam (1) is greater than the external diameter of waterproof membrane (2).
