Abstract

The utility model provides an anti-pollution whistle comprising a whistle main body and a whistle opening, the whistle main body is a spherical main body with a lower half portion heavier than an upper half portion, and the whistle opening is fixed at the upper half portion of the whistle main body. A whistle is improved, and the problem that how to prevent the whistle from being polluted is solved.

Description

A kind of anti-pollution whistle

Technical field

The utility model relates to a kind of whistle, relates in particular to a kind of anti-pollution whistle.

Background technology

Whistle is gadget conventional during people live, but whistle falls on the ground easily whistle mouth is polluted, and when reusing, can bring bacterium into user in the mouth, affects health.Therefore, how preventing that whistle mouth is contaminated, is the problem that is worth solution.

Summary of the invention

The purpose of this utility model is how to prevent the contaminated problem of whistle mouth in order to solve, and proposes a kind of. the technical scheme of anti-pollution whistle, the utility model is achieved through the following technical solutions.

The utility model provides a kind of anti-pollution whistle, comprises whistle main body and whistle mouth, and described whistle main body is the latter half spherical main heavier than the first half, and described whistle mouth is fixed on the first half of described whistle main body.

Whistle lightness sensation in the upper and heaviness in the lower, the latter half of whistle main body is first landed, and after landing, spherical whistle main body is adjusted rapidly center of gravity, has guaranteed that the first half of whistle main body does not land, thereby has kept being fixed on whistle mouth clean of the first half of whistle main body.

The utility model can also further improve by the following technical programs: preferred, the latter half of described whistle main body is solid semisphere, and the first half is hollow hemisphere shape.Thereby make whistle main body lightness sensation in the upper and heaviness in the lower, guaranteed that the first half of whistle main body does not land when whistle lands.

Preferably, described whistle main body is a hollow ball, and the bottom of described hollow ball is fixed with a heavy metal piece.Thereby make whistle main body lightness sensation in the upper and heaviness in the lower, guaranteed that the first half of whistle main body does not land when whistle lands.

Compared with prior art, the utility model has been obtained following technique effect: the improvement by the utility model to whistle, make whistle lightness sensation in the upper and heaviness in the lower, the latter half of whistle main body is first landed, after landing, spherical whistle main body is adjusted rapidly center of gravity, has guaranteed that the first half of whistle main body does not land, thereby kept being fixed on whistle mouth clean of the first half of whistle main body, thereby solved the contaminated problem of whistle mouth that how to prevent.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of embodiment of the utility model.

Mark in figure: 1-whistle main body; 2-whistle mouth; 3-heavy metal piece.

Embodiment

For those skilled in the art being understood more accurately and implementing the utility model, below in conjunction with drawings and Examples, the utility model is further detailed.

Embodiment:

Fig. 1 is this routine structural representation, as shown in Figure 1, this routine anti-pollution whistle comprises whistle main body 1, whistle mouth 2 and heavy metal piece 3, and described whistle main body 1 is a hollow ball, described whistle main body is a hollow ball, and the bottom of described hollow ball is fixed with a heavy metal piece 3.Described whistle mouth 2 is fixed on the first half of described whistle main body 1.

Whistle lightness sensation in the upper and heaviness in the lower, while landing, the latter half of whistle main body 1 is first landed, after landing, under the Action of Gravity Field of heavy metal piece 3, spherical whistle main body 1 is adjusted rapidly center of gravity, has guaranteed that the first half of whistle main body 1 does not land, thereby has kept being fixed on whistle mouth 2 clean of the first half of whistle main body 1.
