Problems solved by technology

[0003] However, in actual use, there are still many shortcomings. When the user uses the survival whistle to call for help, the saliva in the mouth will be transferred to the inside of the survival whistle, and the particles and dust in the air will adhere to the survival whistle. It makes the inside of the survival whistle more and more dirty, and the whole is not easy to disassemble for cleaning, which will cause bacteria to grow inside and rust

Abstract

The invention discloses a novel survival whistle, and particularly relates to the technical field of whistles. The novel survival whistle comprises a whistle body and upper end covers, wherein the setof upper end covers is installed on the whistle body; openings are respectively formed in two sides of the whistle body; an inclined baffle set is arranged in each opening; a positioning seat is fixedly installed on the inner wall of the upper end cover; and a locking piece is embedded into the side surface of the whistle body. According to the novel survival whistle provided by the invention, via integrated design, the whistle body adopts the detachable upper end cover; by using the elastic force characteristic of an expansion pipe and a reset spring, a positioning rod moves in the positioning seat, so that dismounting and mounting of the upper end cover and the whistle body are completed, stability after mounting is ensured, and thus the semi-open type whistle body is exposed outwards,a user is convenient to clean and maintain the interior of the whistle, particles attached to the interior of the whistle are effectively eliminated, the good cleaning effect is ensured, the service life is prevented from being reduced by corrosion in the whistle, and the relatively high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of whistles, and more specifically, the invention relates to a novel survival whistle. Background technique [0002] Whistle refers to a device that can blow out a sharp sound, which is used to send orders when gathering people, training or sports competitions. Among them, the survival whistle is used as a rescue device in field operations. [0003] However, in actual use, there are still many shortcomings. When the user uses the survival whistle to call for help, the saliva in the mouth will be transferred to the inside of the survival whistle, and the particles and dust in the air will adhere to the survival whistle. It makes the inside of the survival whistle more and more dirty, and it is not easy to disassemble and clean it as a whole, which will cause bacteria to grow inside and rust. Contents of the invention [0004] In order to overcome the above-mentioned defects of the prior art, the embodiment...
