Novel telephone receiver dual-filtering dustproof net

Abstract

The invention discloses a novel telephone receiver dual-filtering dustproof net. The dustproof net comprises a first dustproof device and a second dustproof device, a first threaded groove is formed in the upper part of the first dustproof device, the first threaded groove can be clamped to the top shell of a telephone receiver, a second threaded groove is formed in the lower part of the first dustproof device, the second threaded groove can be clamped to the bottom shell of the telephone receiver, a groove is formed in the inner wall of the first dustproof device, an adsorption dustproof netis arranged on the groove, adsorption particles are arranged on the adsorption dustproof net, a taking opening is formed in the inner wall of the first dustproof device, a hanging piece is arranged onthe side wall of the first dustproof device, a clamping piece is arranged on the lower part of the first dustproof device, the clamping piece is buckled with the second dustproof device, the second dustproof device is provided with a clamping ring, a dustproof fiber net is clamped in the middle of the clamping ring, and reinforcing wires are woven on the dustproof fiber net. Dusts entering the telephone receiver can be filtered in a dual-filtering manner, and the dusts are prevented from entering a core part to influence the normal use of the telephone receiver.

Description

technical field [0001] The invention relates to the technical field of dust-proof nets, in particular to a novel dual-filter dust-proof net for receivers. Background technique [0002] The application of the receiver is very extensive and the quantity is very large, but limited to the structure of the receiver, it is very easy to get dust and difficult to handle, thus affecting the normal use of the receiver, so the scrap rate of the receiver is high, and the cost is also very high. The dust-proof net has a simple structure, only one layer and absorbs less dust, which cannot deal with the problem of dust entering the receiver well. Contents of the invention [0003] The purpose of the present invention is to provide a new double-filter dust-proof net for the receiver, which can double filter the dust entering the receiver, prevent the dust from entering the core components and affect the normal use of the receiver, and solve the problems in the prior art.
