Sheng bucket general constant temperature bar

Abstract

The present invention discloses a Sheng bucket general constant temperature bar. The Sheng bucket general constant temperature bar comprises a double-threaded screw and a heating bar. The double-threaded screw is arranged as a hollow structure, and a spacing piece is arranged at the middle portion of the body of the double-threaded screw in a direction being perpendicular to the axis of the double-threaded screw; the inner end of the double-threaded screw is connected with the heating bar in a sleeving mode, the conductive wire of the heating bar penetrates the hollow structure of the double-threaded screw and then is exposed at the other end; the outer end of the double-threaded screw is provided with an electrifying joint; and the electrifying joint is connected with the conductive wireof the heating bar. The core part of the Sheng bucket general constant temperature bar is a resistance heating bar to convert electric energy to heat energy, the resistance heating bar and screws areassembled and reconstructed to easily allow the Sheng bucket to be put in the constant temperature bar to replace the original screws, after electrifying, the voltage can be regulated in an assigned range to perform rapid temperature rise or continuous heating to a constant temperature for the Sheng bucket so as to solve the water filling problem in a musical instrument.

Description

technical field [0001] The invention belongs to the technical field of national musical instruments, and in particular relates to a universal constant temperature rod for Sheng Dou. Background technique [0002] At present, most of my country's sheng instruments use copper sheng buckets, with a water tank compartment at the bottom. Due to the particularity of the sheng structure, the water vapor in the exhaled air of the player will condense on the reeds during the performance, hindering pronunciation. The problem of water filling. Watering the instrument for a long time will lead to problems such as insensitivity of pronunciation, reed falling off, or pitch deviation. Temperature, so that the water vapor in the air chamber evaporates when playing, making the instrument sound better and last longer. But this method is too cumbersome. After long-term use tests, the best use time after injecting hot water can only be maintained at about 20 minutes, and it is even shorter in win...

AI Technical Summary

Problems solved by technology

In addition, there is already a kind of electric heating constant temperature Sheng Dou on the market, but because the heating area is integrated with the Sheng Dou, it is easy to be damaged by pure dry burning, and it is troublesome to replace, and the Sheng Dou needs to be replaced. feel
