The utility model is simple in structure, convenient in assembly and adjustable in timbre, and is a simple and practical phonatory whistle.
Description
Technical field
The utility model relates to a kind of steam whistle.
Background technology
The version of steam whistle has a variety of, generally is at the air intake opening place of flute pipe one vibrating diaphragm to be set, and diaphragm vibrates and sounds when being blown into air-flow, and most of steam whistle can only just be sounded when a direction is blown.
The utility model content
The utility model technical issues that need to address provide a kind of novel structure, steam whistle easy to assembly.
For achieving the above object, technical solution adopted in the utility model is:
It comprises diaphragm, the gas bowl of wandering, flute pipe, is provided with support ring in the flute pipe, and diaphragm and the corresponding gas bowl of wandering thereof are set in the support ring.The projection on the last plane of the size of diaphragm, shape and the gas bowl of wandering is corresponding.
The shape of gas bowl of wandering is only wooden boat shape, and its two ends sink to forming air inlet breach.Its horizontal section is a U-shaped, sees that vertically its middle part suitable for reading is a straight line, and the two ends of upper port plane are bent downwardly, and the middle part of its longitudinal cross-section is recessed.
The cylindrical of flute pipe is provided with bayonet socket, and the end face of an end of flute pipe is provided with backstop.
Adopt the beneficial effect that technique scheme produced to be:
The utility model is simple in structure, and diaphragm, the gas bowl of wandering, support ring and flute pipe be assembled formation successively, and be easily manufactured.The recessed only wooden boat shape design in two of gas bowl of wandering makes the air-flow easy access, can no matter air-flow at which mouthful of flute pipe is blown into, steam whistle be sounded because of air-flow is too big and stuck.And the utility model can use for a long time, is not easy to damage.Bayonet socket on the flute pipe can assemble with other device, prevents that steam whistle position when blowing is moved, and backstop can prevent that the accessory in the flute pipe is blown.
