Description

Technical Field

[0001] This utility model relates to the field of gourd flutes, and in particular to a modular anti-drooling gourd flute. Background Technology

[0002] The hulusi is a reed instrument with distinctive ethnic characteristics, widely popular among the Dai and Achang ethnic minorities in Yunnan Province. Its structure mainly consists of a gourd, a main pipe, auxiliary pipes, and reeds. The gourd acts as the air chamber and soundbox, responsible for storing and transmitting airflow and enhancing the tone. The main pipe has multiple tone holes; the player changes the airflow path by pressing these holes with their fingers, thus controlling the pitch and achieving melodic performance. The auxiliary pipes provide resonance and harmonic effects, enhancing musical expressiveness. The reeds, as the core sound-producing component, vibrate when airflow passes through them; their material and shape directly affect the timbre and volume.

[0003] During the performance, the airflow exhaled by the player enters the inside of the hulusi through the mouthpiece, driving the reeds to vibrate and produce sound. By operating the main tone hole with the fingers, vibrations of different frequencies are produced, forming a rich variety of notes.

[0004] A common problem with existing hulusi (a type of gourd flute) is that a large amount of saliva enters the instrument during playing. Due to the hulusi's unique structure, the gourd part is ultrasonically welded, and the two plastic parts are integrated into a single unit. The disadvantage of this integrated design is that the burrs on both sides are large, making manual polishing difficult. Furthermore, the residual saliva is difficult to drain and clean. Over time, this accumulation not only breeds bacteria and produces odors but may also corrode components such as the reeds and bamboo tubes, leading to poor pitch, damaged tone, and even a shortened lifespan. In addition, the existing technology makes the opening and closing of the tone holes in the auxiliary tube inconvenient and requires improvement. Therefore, we propose a modular saliva-proof hulusi. Utility Model Content

[0005] Purpose of the utility model: The purpose of this utility model is to provide a whole that is easy to disassemble, does not require welding, has good sealing performance, and allows residual saliva to be easily discharged and cleaned; another purpose of this utility model is to provide convenient control over the opening and closing of the sound hole in the auxiliary tube.

[0006] Technical Solution: A modular anti-drooling gourd includes an integrated gourd with locking grooves on both sides. An arc-shaped side plate is locked into the inner side of each locking groove. A mounting base is locked into the bottom of the integrated gourd. A main pipe connector is integrally formed at the center of the lower surface of the mounting base. Auxiliary pipe connectors are fixedly connected to the lower surface of the mounting base on both sides of the main pipe connector. A main pipe sound-emitting tube is inserted into the main pipe connector. A main pipe body is locked into the lower outer wall of the main pipe sound-emitting tube. An auxiliary pipe sound-emitting tube is inserted into the auxiliary pipe connector. An auxiliary pipe body is locked into the lower outer wall of the auxiliary pipe sound-emitting tube. A sound hole is formed on the front surface of the auxiliary pipe body.

[0007] Furthermore, a mouthpiece is inserted into the top of the integrated gourd.

[0008] Furthermore, the interior of the engaging groove has two integrally formed insertion tubes, and the inner side of the arc-shaped side plate is fixedly connected to the inner side of the insertion tubes, with the insertion tubes engaging with the insertion tubes.

[0009] Furthermore, both the outer wall of the main sound-emitting tube and the outer wall of the auxiliary sound-emitting tube are fitted with sealing rings.

[0010] Furthermore, an air outlet pipe is inserted into the inside of the sound hole, and an adjustment seat is integrally formed on the front surface of the air outlet pipe. A sealing piece is slidably connected to the inner side of the adjustment seat.

[0011] Beneficial effects: The modular design allows the gourd to be assembled in parts. Compared with the traditional ultrasonic welding structure of gourds, which has large burrs and is difficult to clean, the one-piece gourd has a sloping internal structure from top to bottom. After playing, the gourd can be turned upside down to pour out the saliva produced during playing directly from the top by pulling out the mouthpiece. This makes it easy to clean up any residual saliva, prevents the accumulation of saliva from breeding bacteria and producing odors, effectively prevents the reed from being corroded, ensures the instrument's pitch and tone, and extends its service life.

[0012] The main sound tube and the auxiliary sound tube are connected to their corresponding joints by a sealing ring, which enhances the sealing performance, makes the airflow more stable, and ensures the stability of tone and volume during performance. The sliding sealing plate set at the tone hole of the auxiliary tube body is more convenient to operate than the traditional auxiliary tube tone hole opening and closing control method. The performer can more flexibly control the resonance and harmony effect of the auxiliary tube, and improve the musical expression.

[0013] Each component adopts a modular connection method such as snap-fit ​​and plug-in, making the assembly and disassembly process simple and convenient. This not only facilitates the production and manufacturing of musical instruments, but also makes it easy to replace and repair when the instrument malfunctions or parts are damaged, reducing maintenance costs and difficulties.
