Description

Mobile phone receiver dust screen

Technical Field

The utility model relates to the technical field of mobile phones, especially, relate to a mobile phone handset dust screen.

Background

The mobile phone is an indispensable communication tool in life, not only gathers information in aspects of work, life and the like, but also is a main tool for entertainment and leisure, so that the importance of the mobile phone is more and more reflected, and the current situation that the mobile phone is not away from the hand in modern life is caused. Because frequent touch to the cell-phone, will pile up a lot of dust carelessly on the dust screen in the cell phone, if untimely clearing up, will cause the jam to the cell phone, serious like sweat stain etc. still can corrode the damage that leads to the fact inside earphone subassembly to wear the dust screen, but because everyone can not in time and the initiative find cell-phone maintenance shop of everybody work and the reason of time and carry out the dust cleaning, so convenient autonomic clearance to the cell-phone earphone dust screen has become a luxurious.

Traditional cell phone dust screen, be the dust screen of one deck, take out old dust screen and then the new dust screen of renewal directly from cell phone mouth department after taking apart the cell-phone back lid in the change, because traditional dust screen still must purchase new dust screen before the change, these reasons all can reduce the desire of independently changing the dust screen, thereby prevent the desire of changing the dust screen, traditional dust screen is the thin dustproof construction of one deck simultaneously, after the cell-phone live time is long, the dust screen is insecure with inside butt, thereby cause the not hard up of dust screen easily, further aggravated dust pollution earphone subassembly, so, one kind can conveniently independently carry out the dust screen clearance and need not change and treat to be designed with the firm cell-phone dust screen of cell-phone butt urgent need.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a mobile phone handset dust screen, the utility model discloses a spacing seat of first spacing fixture block and the spacing fixture block card of second with dust screen integrated into one piece is gone into and is guaranteed that the dust screen does not take place the displacement after cell-phone live time is of a specified duration, guarantee dust screen and the inseparable laminating of cell-phone handset listen barrel mouth simultaneously through the butt layer of dust screen bottom, hold between the fingers the piece through the hand and can be easily take out the dust screen from spacing seat after opening the cell-phone after-cover and clean the back and install, convenient and fast, need not go to look for the place of repairing the cell-phone, oneself can operate.

The utility model discloses an above-mentioned technical problem is solved to following technical means:

the utility model discloses a cell-phone earphone dust screen include the dust screen, with the hand that the one end of dust screen rotated the connection through the pivot is held between the fingers the piece, dust screen integrated into one piece has first spacing fixture block and the spacing fixture block of second, there is the butt layer dust screen bottom through the spring butt the dust screen card has connect spacing seat, the first spacing fixture block of dust screen and the spacing fixture block of second card respectively go into establish first joint groove and the second joint groove at spacing seat both ends. The first clamping groove and the second clamping groove which are arranged at two ends of the limiting seat are respectively clamped by the first limiting clamping block and the second limiting block, so that the dust screen is prevented from displacing, and the mobile phone receiver is firmly plugged by the dust screen. The hand that connects through the pivot is held between the fingers the piece and is installed one side of the back rotatable spacing seat, does not occupy other space volumes, the width that the hand was held between the fingers fast is unanimous with spacing base's thickness.

Further, the dust screen includes waterproof layer, second dust layer and the first dust layer that sets up from bottom to top, the waterproof layer bonds with the second dust layer, the second dust layer bonds with first dust layer.

Further, the surface of the first dust-proof layer is provided with sound holes.

Furthermore, an earphone component cavity is formed between the first clamping groove and the second clamping groove of the limiting seat, and the earphone component cavity is used for installing an earphone component. Because the earphone subassembly carries out the butt with the butt layer, the intraformational spring of butt keeps the elasticity butt constantly to with the firm butt of dust screen at the earphone opening part of cell-phone, avoid taking place the displacement and cause a large amount of entering mobile phone handsets of dust.

Furthermore, the first dust-proof layer and the second dust-proof layer are both made of fiber dust-free cloth materials, the waterproof layer is made of gel materials, and micropores communicated with the sound holes in the first dust-proof layer are formed in the second dust-proof layer and the waterproof layer.

The utility model has the advantages that: the utility model discloses a spacing seat of first spacing fixture block and the spacing fixture block card of second with dust screen integrated into one piece is gone into and is guaranteed that the dust screen does not take place the displacement after cell-phone live time is of a specified duration, guarantee simultaneously through the butt layer of dust screen bottom that the dust screen is listened the inseparable laminating of nozzle with the cell-phone, hold between the fingers the piece simultaneously behind the opening cell-phone and can take out the dust screen from spacing seat easily and clean the back and install again, convenient and fast, need not go to look for the place of repairing the cell-phone, oneself can operate.
