Police interphone with dustproof protection structure

Abstract

The invention discloses a police interphone with a dustproof protection structure, relates to the technical field of interphone dust prevention, and solves the problems that a radio slot and a filter screen of an existing interphone are relatively small, internal dust is easy to accumulate, the external part is not easy to clean through wiping, and dust removal is not thorough. The police interphone with the dustproof protection structure comprises an interphone body, wherein the back side of the interphone body is screwed and fixed with a dustproof installation shell through a screw. When the interphone body is used, air blowing and dust removal operation can be carried out from the interior of the interphone body to a sound receiving and playing part through the dust removal pump air channel by virtue of the back-embedded inner dust removal assembly, air can act on dust accumulated on a filter screen and a sound receiving groove part from the interior, and the dust removal is thorough, convenient and efficient; meanwhile, the two gas compression cavities and the two piston push pieces are matched to alternately compress and suck air for dust removal, gas supply is continuous, and the dust removal effect is better.

Description

technical field [0001] The invention belongs to the field of dust-proof technology for walkie-talkies, and more specifically relates to a police walkie-talkie with a dust-proof protection structure. Background technique [0002] The walkie-talkie is a two-way mobile communication tool. It can be used without any network support, and there is no call fee. It is suitable for relatively fixed and frequent calls. The police often use the walkie-talkie when they go out to perform tasks. In order to enhance the effect of radio reception and playback, the walkie-talkie will set up a radio slot at the position of radio reception and playback, and install a dust-proof filter or a dust-proof filter at the bottom of the radio slot to prevent dust. [0003] For example, in the patent with application number CN201210430087.7, a walkie-talkie with detachable and washable loudspeaker dustproof structure is disclosed, including a cover shell, loudspeaker and loudspeaker dustproof structure;...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a police walkie-talkie with a dust-proof and protective structure to solve the problems of the existing walkie-talkie receiving and playing parts. Because there are sound receiving grooves, the dust in these parts is easy to accumulate in the dust-proof area during use. On the filter or dust-proof filter, the sound receiving groove is blocked, which affects the normal sound volume of the walkie-talkie. At present, when cleaning these dusts, the external rags are used to wipe and remove the internal dust in the collection groove. Because The radio slot and filter are small, not easy to operate, the dust removal is not thorough, the effect is poor, and the practicability is not high
