After the performer blows air into the mouthpiece 31, the swing piece 33 swings to the right, and the airflow is finally discharged through the exhaust port of the air hood 2. At the same time, the swing piece 33 drives the No. 2 gear 35 to rotate a certain amount through the No. 1 gear 34 The second gear 35 drives the speed regulating lever 38 to rotate a certain angle through the third gear 36. As the rotation angle of the speed regulating lever 38 increases, the speed of the motor 37 also increases accordingly. A boost cylinder 313 is installed on the top surface of the air hood 2. A piston 312 is slidably installed on the inner wall of the boost cylinder 313. A telescopic shaft 311 is connected to the right side of the piston 312. The telescopic shaft 311 penetrates the right side of the boost cylinder 313. The telescopic shaft 311 is slidably connected to the right side of the boost cylinder 313. The end of the telescopic shaft 311 away from the piston 312 is connected to a slide frame 310. The output end of the motor 37 is connected to a cam 39. A bearing is arranged on the front side of the cam 39. The bearing is eccentrically arranged. A slide frame 310 is provided with a slide. The bearing is slidably connected to the slide of the slide frame 310. Two air inlet pipes 315 are installed on the rear side of 313, and an air outlet pipe 314 is arranged on the top of the boost cylinder 313. The left side of the air hood 2 is connected to the air cylinder 316 through a bracket. The air outlet pipe 314 is provided with two branch pipes and an air outlet. The two branches of the air outlet pipe 314 are connected to the boost cylinder 313. One of the air inlet pipes 315 and one of the branches of the air outlet pipe 314 are located on the right side of the piston 312, and the other air inlet pipe 315 and the other branch pipe of the air outlet pipe 314 are located on the left side of the piston 312. Check valves are respectively arranged in the two branches of the two air inlet pipes 315 and the air outlet pipe 314. The check valves in the two branches and the two air inlet pipes 315 can prevent gas from flowing back and forth, so that the gas in the pipe can only flow in one direction. When the piston 312 moves back and forth left and right,The two branches can alternately inject air into the air outlet pipe 314, the air outlet of the air outlet pipe 314 is connected to the air cylinder 316, the air outlet pipe 314 injects air into the air cylinder 316 through the air outlet, the reed 9 is located in the air cylinder 316, the air pressure in the air cylinder 316 increases, and the air is blown into the reed 9, so that the suona body 7 makes a sound, and then the performance is completed through fingering. As the strength of the breath blown into the mouthpiece 31 by the performer is different, the swinging amplitude of the swinging piece 33 caused by the airflow is also different. When the breath strength is strong, the swinging amplitude of the swinging piece 33 is larger, the speed of the motor 37 is adjusted faster, and the air intake of the air cylinder 316 is increased. In addition, a counterweight rod is provided at the bottom of the swing piece 33. When there is no blowing or the breath is weakened, the swing piece 33 is reset or the swing amplitude is reduced by gravity, the speed of the motor 37 is reduced, and the air intake of the air cylinder 316 is reduced; the speed regulating rotating rod 38 is away from the front side of the shell 1, and the speed regulating rotating rod 38 is rotatably connected to the front side of the shell 1. The front end of the speed regulating rotating rod 38 is connected to an adjusting rod 317, and the adjusting rod 317 can be externally connected to an extension rod, so that the extension rod is located at a position that the performer can press with his arm. When continuous performance is required, the performer can use his arm to press when breathing when he does not circulate and breathe. The arm presses the extension rod to temporarily fix the adjustment rod 317, so that the motor 37 maintains the current speed. After the performer completes breathing, the extension rod is released to continue playing to avoid interruption of the performance. Through the setting of the breath amplifier device 3, the swing plate 33 swings to different degrees according to the strength of the performer's breath, and then the speed of the motor 37 is adjusted according to the swing angle of the swing plate 33 by the speed regulating rod 38, thereby adjusting the air intake of the air cylinder 316, and using mechanical air intake instead of artificial blowing. The air intake of the mechanical air intake can be automatically adjusted according to the strength of artificial blowing, so that the performer can blow out smaller After the breath is taken, after the amplification conversion of the breath amplifier device 3, the air cylinder 316 blows enough air into the reed 9. When the performer adjusts the breath size, the air volume of the air cylinder 316 can also be automatically adjusted with the performer's breath, which is convenient for children and people with unstable breath. The performer only needs to grasp the rhythm of blowing out the breath, which reduces the breath pressure when playing a conventional suona; through the setting of the adjustment rod 317, the performer can use the external adjustment rod 317 to temporarily keep the motor 37 rotating when the performer needs to breathe during continuous performance, so that the gas delivery of the air cylinder 316 is uninterrupted, maintaining the continuity of the performance.

[0034] For further information, see Figure 7 - Fig. 9The saliva cleaning device 4 is used to clean the saliva and condensed water in the air hood 2. The saliva cleaning device 4 is arranged in the air hood 2. The saliva cleaning device 4 includes a sliding rod 41, which is slidably installed on the top inner wall of the air hood 2. One end of the sliding rod 41 is connected to the slide slot frame 310, and the other end of the sliding rod 41 is connected to two connecting rods 42 through a hinge. Two swing arms 43 are rotatably installed on the mounting shaft 32. The two swing arms 43 are respectively located on the front and rear sides of the swing plate 33. The ends of the two connecting rods 42 away from the sliding rod 41 are respectively connected to the two swing arms 43 through sliding hinges. The ends of the two swing arms 43 away from the mounting shaft 32 are connected with scraping strips 44. When the sliding rod 41 moves back and forth left and right, the two connecting rods 42 drive the two swing arms 43 to swing back and forth left and right. The swing arm 43 drives the scraper bar 44 to swing synchronously. The two swing arms 43 can scrape off most of the accumulated water on the inner walls of the front and rear sides of the air hood 2, and the scraper bar 44 can scrape off the accumulated water on the inner wall of the left side and the bottom of the air hood 2. The bottom of the air hood 2 is connected to a collecting box 45, and a square hole is provided at the connection between the collecting box 45 and the air hood 2. The accumulated water eventually enters the collecting box 45 through the square hole for collection, thereby achieving the effect of automatically cleaning the inside of the air hood 2; the saliva cleaning device 4 also includes two sliding shafts 46, and a No. 1 slide groove 47 is respectively provided on the inner walls of the front and rear sides of the square hole of the air hood 2, and a No. 2 slide groove 48 is respectively provided on the inner walls of the front and rear sides of the collecting box 45, one of the sliding shafts 46 is slidably installed between the two No. 1 slide grooves 47, and the other sliding shaft 46 is slidably installed between the two No. 2 slide grooves 48. A cover plate 49 is connected to a sliding shaft 46, a lever 410 is connected to the cover plate 49, a push rod 411 is connected to the scraper strip 44, the push rod 411 contacts the lever 410 during movement, and contacts the lever 410 and pushes it to the right when the push rod 411 moves to the right. The two No. 1 slide grooves 47 are arranged horizontally, and the two No. 2 slide grooves 48 are arranged vertically. When the cover plate 49 moves, the left sliding shaft 46 slides to the right along the two No. 1 slide grooves 47, and the right sliding shaft 46 slides downward along the two No. 2 slide grooves 48, so that the cover plate 49 gradually changes from horizontal to vertical, so that the cover plate 49 is opened. A disinfection lamp 412 is installed on the bottom surface of the cover plate 49, and the disinfection lamp 412 irradiates and disinfects the accumulated water below to prevent bacteria from growing in the air hood 2. The bottom of the cover plate 49 is connected to the collection box A return spring is arranged between the bottom inner walls of 45. After the scraper bar 44 and the push rod 411 move to the right, the cover 49 is reset by the elastic force of the return spring, and the two sliding shafts 46 are reset accordingly, and the cover 49 is closed at this time; through the arrangement of the saliva cleaning device 4, during the performance, the two swing arms 43 and the scraper bar 44 can continuously scrape the saliva and condensed water in the air hood 2 into the collection box 45 for collection, thereby achieving a self-cleaning effect; through the arrangement of the cover 49, the cover 49 can be automatically opened when the scraper bar 44 approaches, and can be automatically closed when the scraper bar 44 moves away, thereby avoiding the reflux of saliva and condensed water in the collection box 45. At the same time, the disinfection lamp 412 at the bottom of the cover 49 can disinfect the reflux of saliva and condensed water in the collection box 45 to avoid the growth of bacteria.

[0035] With the above structure, the working principle of this case is that the buckle 6 can be opened, and after the buckle 6 is buckled on the suona body 7 to be connected, the buckle 6 is closed, and the buckle 6 connects the suona body 7 to the shell 1 through the connecting rod 5. The air cylinder 316 can be disassembled. After the air cylinder 316 is disassembled, the reed 9 and the suona core 8 are installed in the air cylinder 316. After starting the motor 37, the speed regulating lever 38 is the speed regulating switch of the motor 37. When the swinging piece 33 does not swing, the speed regulating switch is in the closed state. After the performer blows air into the mouthpiece 31, the swinging piece 33 swings to the right, and the airflow is finally discharged through the exhaust port of the air cover 2. At the same time, the swinging piece 33 drives the second gear 35 to rotate a certain angle through the first gear 34, and the second gear 35 drives the speed regulating lever 38 through the third gear 36. The rotating rod 38 rotates a certain angle. As the rotation angle of the speed regulating rotating rod 38 increases, the speed of the motor 37 also increases. When the motor 37 rotates, the cam 39 is driven to rotate through the output end. The cam 39 drives the slide frame 310 to move back and forth left and right through the cooperation of the bearing and the slide. The slide frame 310 drives the piston 312 to slide back and forth left and right in the boost cylinder 313 through the telescopic shaft 311. When the piston 312 moves to the left, the piston 312 squeezes the air on its left side into the outlet pipe 314 through the left branch pipe. At the same time, the piston 312 draws air into the boost cylinder 313 through the right intake pipe 315. When the piston 312 moves to the right, the piston 312 squeezes the air on its right side into the outlet pipe 314 through the right branch pipe. At the same time, the piston 312 draws air into the boost cylinder 313 through the left air inlet pipe 315. The two branch pipes and the check valves in the two air inlet pipes 315 can prevent gas from flowing back, so that the gas in the pipe can only flow in one direction, so that when the piston 312 moves back and forth left and right, the two branch pipes can alternately inject air into the air outlet pipe 314, and the air outlet pipe 314 injects air into the air cylinder 316 through the air outlet. After the air pressure in the air cylinder 316 increases, the air is blown into the mouthpiece 9, so that the suona body 7 makes a sound, and then the performance is completed through fingering. As the strength of the breath blown into the mouthpiece 31 by the performer is different, the swing amplitude of the swinging piece 33 caused by the air flow is also different. When the breath strength is strong, the swing amplitude of the swinging piece 33 is larger, and the first gear 3 The angle of rotation of the third gear 36 driven by the second gear 35 is also large, so that the speed of the motor 37 is adjusted faster, the moving frequency of the piston 312 is increased, and the air intake of the air cylinder 316 is increased. A counterweight rod is arranged at the bottom of the swing plate 33. When there is no blowing, or the breath is weakened, the swing plate 33 is reset or the swing amplitude is reduced by gravity. The same principle as above, the speed of the motor 37 is reduced, and the air intake of the air cylinder 316 is reduced. When the swing plate 33 is completely reset, the motor 37 stops rotating. The adjustment rod 317 can adjust the angle of the speed regulating rod 38 outside the housing 1. The adjustment rod 317 can be connected to an extension rod so that the extension rod is located at a position that is convenient for the performer to press with his arm. When continuous performance is required, the performer will not circulate and breathe.When breathing, the performer can press the extension rod with his arm to temporarily fix the adjustment rod 317, so that the motor 37 maintains the current speed. After the performer has completed breathing, he can release the extension rod and continue to play, avoiding interruption of the performance. Through the setting of the breath amplifier device 3, the swing plate 33 produces different degrees of swing according to the strength of the performer's breath, and then the speed of the motor 37 is adjusted according to the swing angle of the swing plate 33 by the speed regulating rod 38, thereby adjusting the air intake of the air cylinder 316, using mechanical air intake instead of artificial blowing, and the air intake of the mechanical air intake can be automatically adjusted according to the strength of artificial blowing, so that the performer can breathe more easily. After blowing out a small amount of air, after the amplification conversion of the breath amplifier device 3, the air cylinder 316 blows enough air into the reed 9. When the performer adjusts the breath size, the air volume of the air cylinder 316 can also be automatically adjusted with the performer's breath, which is convenient for children and people with unstable breath. The performer only needs to grasp the rhythm of blowing out the breath, which reduces the breath pressure when playing a conventional suona; through the setting of the adjustment rod 317, the performer can use the external adjustment rod 317 to temporarily keep the motor 37 rotating when the performer needs to breathe during continuous performance, so that the gas delivery of the air cylinder 316 is uninterrupted, maintaining the continuity of the performance.

[0036] After long-term use, some saliva and condensed water will accumulate in the air hood 2 to form accumulated water. When the slide chute frame 310 reciprocates left and right, it drives the slide bar 41 to reciprocate left and right. When the slide bar 41 reciprocates left and right, it drives the two swing arms 43 to swing back and forth left and right through the two connecting rods 42. The two swing arms 43 drive the scraper 44 to swing synchronously. The two swing arms 43 can scrape off most of the accumulated water on the inner walls of the front and rear sides of the air hood 2, and the scraper 44 can scrape off the accumulated water on the inner walls of the left side and the bottom of the air hood 2. The water finally enters the collection box 45 through the square hole for collection, thereby achieving the effect of automatically cleaning the inside of the air hood 2; when the scraper 44 moves, it drives the push rod 411 to move synchronously, and when the push rod 411 moves to the right, it contacts the lever 410 and pushes it to the right, and when the lever 410 moves to the right, it drives the cover plate 49 to move to the right. When the cover plate 49 moves, the left sliding shaft 46 slides to the right along the two No. 1 slide grooves 47, and the right sliding shaft 46 slides downward along the two No. 2 slide grooves 48, so that the cover plate 49 is moved by The horizontal direction gradually changes to the vertical direction, so that the cover 49 is opened. After the cover 49 is opened, the scraper 44 scrapes the accumulated water into the collection box 45. After the scraper 44 and the push rod 411 move to the right, the cover 49 is reset by the elastic force of the reset spring, and the two slide shafts 46 are reset accordingly. At this time, the cover 49 is closed. After the cover 49 is closed, the disinfection lamp 412 at the bottom of the cover 49 irradiates and disinfects the accumulated water below to prevent bacteria from growing in the air cover 2.
