Abstract
The utility model provides an anti-pollution whistle comprising a whistle body. The whistle body comprises a whistle opening and a whistle cavity. The whistle opening is provided with a protecting device which is formed by two fan-shaped protecting covers and an annular pedestal fixed to the whistle opening. One end of each fan-shaped protecting cover is fixed to the annular pedestal. With protruding central parts, the fan-shaped protecting covers cover the whistle opening and can be engaged and disengaged, like a freshwater mussel wholly. The annular pedestal is provided with a switch. The bottom of the switch is provided with a spring. When the switch is pressed, the spring is compressed and the fan-shaped protecting covers are disengaged automatically. The protecting device is movably connected with the whistle body and can be detached integrally. The outer parts of the fan-shaped protecting covers are provided with rubber coatings, so that the impact resistance is improved. According to the technical theme, the whistle opening can be isolated from pollution sources during use and be kept clean.
Description
Technical field
The utility model relates to the expansion field of whistle function, relates in particular to a kind of anti-pollution whistle.
Background technology
Whistle is a kind of implements that can blow out high frequency sound, still can clearly hear in noisy environment because the sound of its high frequency makes it, and therefore whistle is used for gathering people, practices or sends out command when sports tournament.Common whistle generally all only has chamber, the whistle and whistle mouth composition, and material is generally divided into stainless steel or plastic material.But these all cannot avoid a problem, be exactly that whistle mouth is easy to contaminated.Because whistle is often to hang upside down in front, user can carry whistle and get around out of doors, and whistle mouth is very easily polluted, and user's health is formed to potential threat.And because whistle can send the sound because of it, very welcome concerning child, child, in the process using, is more easily polluted.
Therefore for above problem, we are not difficult to find, existing whistle still haves much room for improvement.
Summary of the invention
In order to solve problem set forth above, we provide a kind of design proposal of anti-pollution whistle.
A kind of anti-pollution whistle; comprise whistle body; whistle body is made up of whistle mouth, whistle chamber; described whistle mouth has protective device, and described protective device is made up of two fan-shaped over caps, described fan-shaped over cap central protuberance; periphery sinks; form freshwater mussel formula form, parcel whistle mouth, expansible closure.
Optimize, the bottom of the fan-shaped over cap of described anti-pollution whistle has individual annular base and can be enclosed within on whistle mouth, has switch on annular base, and described switch bottom has spring, pins switch, and spring produces after compression, and fan-shaped over cap is opened automatically; In the time that needs are closed fan-shaped over cap, user manually closes up fan-shaped over cap and can close.
Optimize, the protective device of anti-pollution whistle can be with whistle body for being flexibly connected, can integral demounting.Be designed to the mode being flexibly connected, not only can dismantle protective device, conveniently whistle mouth is carried out to cleaning-sterilizing; And damaged when over cap generation, can take off separately the whistle protective device that uses whistle or more renew, economize on resources.
Optimize, the fan-shaped over cap outside of described anti-pollution whistle has rubber coating, increases resistance property.Described rubber coating, is evenly attached on fan-shaped over cap, and rubber layer has certain elasticity, when whistle lands or occur to clash into the effect that can play protection.
The technique effect that the utility model is obtained:
The technological improvement of whistle being carried out by the utility model, makes common whistle on not obvious increase cost basis, increases a protective device at whistle mouth place, and protection whistle mouth avoids contact stain source, thereby further protect, user's is healthy.And protective device can arbitrarily dismantle, more convenient like this user cleans or changes protective device, meets environmental protection concept.
Brief description of the drawings
Fig. 1 is that the protective device of the anti-pollution whistle of the utility model is opened schematic diagram;
Fig. 2 is the closed schematic diagram of the protective device of the anti-pollution whistle of the utility model.
Embodiment
It is a kind of that the utility model provides, and for making the purpose of this utility model, technical scheme and effect clearer, clear and definite, below the utility model further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment
Refer to shown in Fig. 1, Fig. 2, the utility model discloses a kind of design proposal of anti-pollution whistle.A kind of anti-pollution whistle, comprises whistle body, and whistle body is made up of whistle mouth 1, whistle chamber 2, and whistle body entirety is stainless steel, and the diameter of whistle mouth 1 is 0.8cm.1 mouthful, described whistle has protective device, and described protective device is made up of two fan-shaped over caps 3 and annular base 4.
Further, described annular base 4 is fixed on whistle mouth 1, and one end of two fan-shaped over caps 3 is separately fixed on annular base 4.After fan-shaped over cap 3 is closed, maximum gauge is 1.2cm, forms freshwater mussel formula form, parcel whistle mouth 1.After described fan-shaped over cap 3 is fixed on annular base 4, the number of degrees variation range of the subtended angle between two fan-shaped over caps 3 is 0 ~ 270 degree.
Further, on described annular base 4, have switch 5, described switch 5 bottoms have spring, pin switch, and spring produces after compression, and fan-shaped over cap 3 is opened automatically; In the time that needs are closed fan-shaped over cap 3, user manually closes up fan-shaped over cap 3 and can close.
Further, described protective device can be with whistle body for being flexibly connected, can integral demounting.Described annular base 4 inwalls have internal thread, whistle mouth 1 corresponding place have an external thread, protective device can be fixed on whistle mouth 1 by rotation.Be designed to the mode being flexibly connected, not only can dismantle protective device, conveniently whistle mouth 1 is carried out to cleaning-sterilizing; And damaged when fan-shaped over cap 3 generations, can take off separately the whistle protective device that uses whistle or more renew, economize on resources.
Further, described fan-shaped over cap 3 outsides have rubber coating, increase resistance property.Described rubber coating is evenly attached on fan-shaped over cap 3, and rubber layer has certain elasticity, when whistle lands or occur to clash into the effect that can play protection.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or convert, all these improvement and conversion all should belong to the protection domain of the utility model claims.
