A new double-filter dust-proof net for receivers

Abstract

The invention discloses a new double-filter dust-proof net for a receiver, which includes a first dust-proof device and a second dust-proof device. The upper part of the first dust-proof device is provided with a first threaded groove, and the first threaded groove can be connected to the top of the receiver. Shell clamping, the lower part of the first dust-proof device is provided with a second threaded groove, the second threaded groove can be engaged with the bottom shell of the receiver, the inner wall of the first dust-proof device is provided with a groove, and the groove is provided with an adsorption-proof Dust net, the adsorption dust net is provided with adsorption particles, the inner wall of the first dust-proof device is provided with a taking port, the side wall of the first dust-proof device is provided with a hanging piece, the lower part of the first dust-proof device is provided with a card, the card card A second dust-proof device is buckled, and the second dust-proof device is provided with a clamp ring, and a dust-proof fiber net is clamped in the middle of the clamp ring, and the dust-proof fiber net is woven with reinforcing wires. The invention can have double filtering effect on the dust entering the receiver, preventing the dust from entering the core components and affecting the normal use of the 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. [0004] To achi...
