Abstract

The utility model discloses a kind of new whistle, whistle head including blow head and provided with cavity, spin is provided with the cavity of whistle head, the section of the cavity of whistle head is circle, the top of described whistle head is provided with opening, described blow head is provided with insufflation channel, and the area of section of the air inlet of insufflation channel is more than the area of section of gas outlet, and described spin is nonmetallic lightweight spin；The beneficial effects of the utility model are：It is reasonable in design, it is simple in construction, there is stronger sound penetration, spread scope is more extensive, can reach effect without the use of too many strength, manufacturing process is simple, and cost is relatively low.

Description

A kind of new whistle

Technical field

The utility model belongs to outdoor gear field, and in particular to be a kind of new whistle.

Background technology

Whistle, refer to a kind of implements that can blow out glouglou, for gathering people, practicing or sending out command during sports tournament, in army The sound penetration that whistle is sent in the outdoor spacious scene such as instruction, physical education is not strong, and spread scope is not wide enough, to use during use The strength fourth of the twelve Earthly Branches is blown hard just effectively enough from head to foot；And the current whistle of in the market is substantially with iron, based on the metallic article such as stainless steel, Weight is big, and manufacturing process is complicated, and cost is higher.

Utility model content

In order to solve the above technical problems, the utility model provides, a kind of penetration power is strong, and spread scope is wide, makes letter Single, the lower new whistle of cost.

To achieve the above object, the technical solution adopted in the utility model is a kind of new whistle, including blow head and is provided with The whistle head of cavity, the cavity of whistle head is interior to be provided with spin, and its structural feature is that the section of the cavity of whistle head is circular, the described whistle The top of head is provided with opening, and described blow head is provided with insufflation channel, and the area of section of the air inlet of insufflation channel is more than gas outlet Area of section, described spin is nonmetallic lightweight spin.

As preferred scheme of the present utility model, the opening above the head of the whistle connects with insufflation channel.

As preferred scheme of the present utility model, the gas outlet opposite side in the opening above the head of the whistle with insufflation channel is provided with Slope.

As preferred scheme of the present utility model, the level height on slope is higher than the level height of insufflation channel.

As preferred scheme of the present utility model, the lower edges of the gas outlet of insufflation channel are equipped with groove.

As preferred scheme of the present utility model, spin is made of foam.

The beneficial effects of the utility model are：It is reasonable in design, it is simple in construction, there is stronger sound penetration, spread scope More extensively, effect is can reach without the use of too many strength, manufacturing process is simple, and cost is relatively low.

Brief description of the drawings

Fig. 1 is cross section structure schematic diagram of the present utility model；

Wherein, 1- blow heads, 2- cavitys, 3- whistles head, 4- spin, 5- openings, 6- blow afloat passage, 7- air inlets, 8- gas outlets, 9- slopes, 10- cuts.

Embodiment

Explanation is further explained to the utility model below in conjunction with the accompanying drawings, but does not limit protection model of the present utility model Enclose.

As shown in figure 1, a kind of new whistle, including blow head 1 and the whistle first 3 provided with cavity 2, it is provided with the cavity 2 at the whistle first 3 Spin 4, the section of the cavity 2 at the whistle first 3 is circle, and the top at the described whistle first 3 is provided with opening 5, and described blow head 1, which is provided with, blows Passage 6, the area of section of the air inlet 7 of insufflation channel 6 are more than the area of section of gas outlet 8 so that only need a small amount of air-flow just Larger sound can be sent, described spin 4 is the spin of nonmetallic lightweight, and the surface of spin 4 is provided with striped, passes through spin 4 resonance increase volume；The opening 5 of first 3 top in the described whistle connects with insufflation channel 6, forms air turbulence；Described whistle head The opposite side of gas outlet 8 in the opening 5 of 3 tops with insufflation channel 6 is provided with slope 9；The level height on described slope 9, which is higher than, blows The level height of gas passage 6；The lower edges of the gas outlet 8 of described insufflation channel 6 are equipped with groove 10, add gas The rate of outflow and outflow pressure；Described spin 4 is made of foam, and cost is relatively low.

It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained All changes in justice and scope are included in the utility model, any reference in claim should not be considered as into limitation Involved claim.

Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art It is appreciated that other embodiment.
