Description

Technical Field

[0001] This invention relates to the field of breathing training aids, and particularly to an adjustable vocal breathing training aid. Background Technology

[0002] In vocal training, breath control directly affects the stability, pitch, and timbre of the voice. Existing vocal breath training aids mainly fall into two categories: simple physical training tools, such as blowing paper, candles, or bubble wands; and electronic breathing trainers. While simple physical tools are inexpensive, they cannot quantify training resistance or finely adjust the pressure according to the trainee's lung capacity or skill level. Beginners struggle to master the correct breath pressure, while advanced learners cannot achieve progressive overload. Electronic breathing trainers typically rely on a power source, are complex in structure, expensive, and inconvenient to carry; some even require professional guidance to operate. More importantly, most existing devices only provide fixed or limited levels of airflow resistance, failing to simultaneously achieve stepless adjustment of the inlet opening pressure and graded adjustment of the outlet training difficulty, thus failing to meet the needs of all stages from basic breath awareness to high-intensity control training.

[0003] Therefore, an adjustable vocal breath training aid device is proposed. Summary of the Invention

[0004] In view of this, the present invention provides an adjustable vocal breath training aid to solve or alleviate one of the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0005] The technical solution of this invention is implemented as follows: An adjustable vocal breathing training auxiliary device includes a housing, an air inlet pipe connected to the outer wall of the housing, an air nozzle at one end of the air inlet pipe, and a plurality of rows of air outlet holes arranged from bottom to top on the outer wall of the housing. A first adjustment knob is rotatably connected to the outer wall of the housing, and the first adjustment knob is fixedly connected to one end of a first threaded rod. A connecting bracket is threadedly connected to the outer wall of the first threaded rod, a limit block is fixedly connected to one side of the connecting bracket, a connecting rod is slidably connected to the inner wall of the limit block, a spring is sleeved on the outer wall of the connecting rod, a top block is fixedly connected to one end of the connecting rod, a sealing ring is fixedly connected to the inner wall of the air inlet pipe, a second adjustment knob is rotatably connected to the top of the housing, and the second adjustment knob is fixedly connected to one end of a second threaded rod. A threaded sleeve is threadedly connected to the outer wall of the second threaded rod, a sealing cylinder is fixedly connected to the bottom of the threaded sleeve, and a through groove is opened on the outer wall of the sealing cylinder.

[0006] A further preferred embodiment: the diameter of the air outlets in the several rows decreases sequentially from bottom to top.

[0007] A further preferred embodiment: a first support plate is fixedly connected to the inner wall of the housing, and the first threaded rod is rotatably connected to one side of the first support plate.

[0008] A further preferred embodiment: the connecting bracket is slidably connected to the outer side wall of the first support plate.

[0009] A further preferred embodiment: the top block is disposed on one side of the sealing ring, and the top block is a conical block.

[0010] A further preferred embodiment: a second support plate is fixedly connected to the inner sidewall of the housing, and the second threaded rod is rotatably connected to the top of the second support plate.

[0011] A further preferred embodiment: the top of the sealing cylinder is a closed end, and the sealing cylinder is slidably connected to the inner wall of the shell.

[0012] A further preferred embodiment is that the through groove is a strip-shaped groove arranged along the axial direction of the sealing cylinder.

[0013] A further preferred embodiment: one end of the spring abuts against the limiting block, and the other end of the spring abuts against the top block.

[0014] A further preferred embodiment: one end of the connecting rod is fixedly connected to a limiting flange.

[0015] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: I. This invention drives the first threaded rod to rotate via a first adjusting knob, causing the connecting bracket to move along the first support plate, thereby compressing the spring. The spring transmits thrust to the top block, causing the pressure of the top block (conical block) on the sealing ring to vary steplessly, thus adjusting the opening pressure of the check valve structure inside the air intake pipe. When the trainee blows air, this preset pressure must be overcome to send airflow into the housing, and the spring provides gentle elastic feedback during the process, avoiding sudden changes in air pressure. By rotating the first adjusting knob, the initial resistance to blowing air can be finely and continuously adjusted to adapt to different lung capacities and different training stages.

[0016] II. This invention uses a second adjusting knob to rotate a second threaded rod, causing the threaded sleeve and sealing cylinder to move up and down. The outer wall of the sealing cylinder has a through groove, and the side wall of the casing has several rows of air outlets with progressively decreasing diameters from bottom to top. When the sealing cylinder moves, the through groove exposes air outlets of different rows and diameters: the larger diameter air outlets at the bottom have low resistance, suitable for low-intensity training; the smaller diameter air outlets at the top have high resistance, suitable for high-intensity breath control training. Users can quickly switch training difficulty using a single knob.

[0017] Third, the air intake resistance adjustment and air output difficulty adjustment of this invention are independent and do not interfere with each other. Trainees can freely combine them according to their own needs: for example, setting a higher air intake opening pressure (blowing forcefully) while opening a small-diameter air outlet (high resistance) is used to enhance the strength of the expiratory muscle groups; or setting a lower air intake pressure while opening a large-diameter air outlet is used to practice stable and gentle long-tone breath output. The device has a compact structure, is purely mechanical and requires no power supply, is small in size and easy to carry. During training, the stability and continuity of breath can be intuitively judged by observing the air output of the air outlet at different heights. It is suitable for breath rehabilitation training for vocal beginners, professional singers, wind instrument players, and patients undergoing throat rehabilitation.

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown, this embodiment of the invention provides an adjustable vocal breathing training aid, including a housing 11. An air inlet pipe 12 is connected to the outer wall of the housing 11. One end of the air inlet pipe 12 is equipped with an air nozzle 13, through which the user blows air into the device. The outer wall of the housing 11 has several rows of air outlet holes 14 arranged from bottom to top to discharge the gas entering the housing 11. A first adjustment knob 15 is rotatably connected to the outer wall of the housing 11. The first adjustment knob 15 is fixedly connected to one end of a first threaded rod 16. A connecting bracket 18 is threadedly connected to the outer wall of the first threaded rod 16. A limiting block 19 is fixedly connected to one side of the connecting bracket 18. A connecting rod 20 is slidably connected to the inner wall of the limiting block 19. A spring 21 is sleeved on the outer wall of the connecting rod 20. A top block 22 is fixedly connected to one end of the connecting rod 20. A sealing ring 23 is fixedly connected to the inner wall of the air inlet pipe 12. When the first adjustment knob 15 is turned, the first threaded rod 16 rotates synchronously, driving the connecting bracket 18 to move axially along the first threaded rod 16. The connecting bracket 18 drives the limiting block 19 to move, and the limiting block 19 pushes the top block 22 to press the sealing ring 23 through the spring 21. Since the degree of compression of the spring 21 changes continuously with the position of the connecting bracket 18, the pressing force of the top block 22 on the sealing ring 23 is also infinitely adjustable, thereby changing the opening pressure of the check valve structure in the air inlet pipe 12. When the user blows air, this preset pressure must be overcome for the airflow to enter the housing 11, thus realizing continuous adjustment of the blowing resistance.

[0025] A second adjusting knob 24 is rotatably connected to the top of the housing 11. The second adjusting knob 24 is fixedly connected to one end of a second threaded rod 25. A threaded sleeve 26 is threadedly connected to the outer wall of the second threaded rod 25. A sealing cylinder 27 is fixedly connected to the bottom of the threaded sleeve 26. A through groove 28 is provided on the outer wall of the sealing cylinder 27. When the second adjusting knob 24 is rotated, the second threaded rod 25 drives the threaded sleeve 26 to move up and down, thereby driving the sealing cylinder 27 to rise and fall inside the housing 11. The outer wall of the sealing cylinder 27 slides and seals against the inner wall of the housing 11. The through groove 28 is a strip-shaped groove arranged along the axial direction of the sealing cylinder 27. As the sealing cylinder 27 rises and falls, the through groove 28 can expose vent holes 14 at different heights. Since the diameter of the several rows of air outlets 14 decreases from bottom to top, when the through groove 28 is aligned with the large diameter air outlet 14 below, the air resistance is small, which is suitable for low-intensity breath training; when the through groove 28 is aligned with the small diameter air outlet 14 above, the air resistance is large, which is suitable for high-intensity breath control training. The training difficulty can be quickly switched by rotating the second adjustment knob 24.

[0026] In this embodiment, specifically, the diameter of the several rows of air vents 14 decreases sequentially from bottom to top. This design makes the training difficulty increase with the height of the air vents, which conforms to the principle of gradual breathing training.

[0027] In this embodiment, specifically: a first support plate 17 is fixedly connected to the inner sidewall of the housing 11, and a first threaded rod 16 is rotatably connected to one side of the first support plate 17. The first support plate 17 provides stable support for the first threaded rod 16, ensuring that it does not wobble during rotation.

[0028] In this embodiment, specifically, the connecting bracket 18 is slidably connected to the outer wall of the first support plate 17. Thus, the connecting bracket 18 is guided by the first support plate 17 during movement, ensuring smooth movement and preventing jamming.

[0029] In this embodiment, specifically: the top block 22 is disposed on one side of the sealing ring 23, and the top block 22 is a conical block. The conical structure can form a linear contact seal with the sealing ring 23, achieving a higher sealing specific pressure under the same spring force, while reducing wear.

[0030] In this embodiment, specifically: a second support plate 29 is fixedly connected to the inner wall of the housing 11, and a second threaded rod 25 is rotatably connected to the top of the second support plate 29. The second support plate 29 provides rotational support for the second threaded rod 25, ensuring that the sealing cylinder 27 remains coaxial when it is raised and lowered.

[0031] In this embodiment, specifically: the top of the sealing cylinder 27 is a closed end, and the sealing cylinder 27 is slidably connected to the inner wall of the housing 11. The closed end prevents gas leakage from the top, and the slidable connection ensures that the sealing cylinder 27 always forms a seal with the inner wall of the housing 11 during the lifting and lowering process.

[0032] In this embodiment, specifically, the through groove 28 is a strip-shaped groove arranged along the axial direction of the sealing cylinder 27. The strip-shaped groove has a simple structure, is easy to process, and can selectively connect to a row of air outlet holes 14 according to the lifting position of the sealing cylinder 27.

[0033] In this embodiment, specifically: one end of the spring 21 abuts against the limiting block 19, and the other end of the spring 21 abuts against the top block 22. The limiting block 19 limits one end of the spring 21. When the connecting bracket 18 moves, the spring 21 is compressed or released, and the amount of compression determines the clamping force of the top block 22 on the sealing ring 23.

[0034] In this embodiment, specifically: one end of the connecting rod 20 is fixedly connected to a limiting flange. The limiting flange is used to prevent the connecting rod 20 from coming out of the limiting block 19, ensuring that the top block 22 always moves axially under the action of the spring 21 and will not deviate from the center position of the sealing ring 23.

[0035] With the above structure, the present invention can independently adjust the air intake resistance and the air exhaust difficulty. The air intake end can steplessly change the blowing opening pressure through the first adjustment knob 15, and the air exhaust end can change the air exhaust resistance in stages through the second adjustment knob 24. The two work together to meet the vocal breath training needs of different lung capacities and different training stages.

[0036] When this invention is in operation: First, an adjustment operation is performed. The user adjusts the air intake resistance and the air exhalation difficulty according to their own breathing level and training goals.

[0037] Adjust the intake resistance (blowing opening pressure): The user rotates the first adjustment knob 15, which in turn rotates the first threaded rod 16. Since the connecting bracket 18 is threadedly connected to the first threaded rod 16 and slidably connected to the outer wall of the first support plate 17, the connecting bracket 18 moves axially along the first threaded rod 16. As the connecting bracket 18 moves, it compresses the spring 21 via the limiting block 19. The spring 21 transmits thrust to the top block 22, causing the top block 22 (conical block) to press against the sealing ring 23. As the rotation angle of the first adjustment knob 15 changes continuously, the compression of the spring 21 also changes continuously, thus allowing for stepless adjustment of the pressure exerted by the top block 22 on the sealing ring 23. A greater pressure requires overcoming the opening pressure of the check valve when the user blows air; a smaller pressure results in a smaller opening pressure. This achieves stepless adjustment of the initial resistance to blowing air.

[0038] Adjusting the difficulty of exhalation (training intensity): The user rotates the second adjustment knob 24, which in turn rotates the second threaded rod 25. The second threaded rod 25 is threadedly connected to the threaded sleeve 26, and a sealing cylinder 27 is fixedly connected to the bottom of the threaded sleeve 26. Since the sealing cylinder 27 is slidably connected to the inner wall of the housing 11 and its top is closed, the sealing cylinder 27 rises or falls inside the housing 11 when the second adjustment knob 24 is rotated. A strip-shaped through groove 28 is provided on the outer wall of the sealing cylinder 27, and several rows of air vents 14 with progressively decreasing diameters are provided on the outer wall of the housing 11 from bottom to top.

[0039] When the sealed cylinder 27 descends to its lowest position, the through groove 28 is only connected to the large-diameter air outlet 14 below, resulting in a large airflow area and low resistance, which is suitable for low-intensity breath training.

[0040] When the sealed cylinder 27 rises to the high position, the through groove 28 connects with the small-diameter air outlet 14 above. The airflow has a small area and high resistance, which is suitable for high-intensity breath control training.

[0041] Breathing training process: After adjustment, the user holds the mouthpiece 13 and blows air into the air inlet pipe 12. When the blowing pressure exceeds the clamping force of the top block 22 on the sealing ring 23, the top block 22 is pushed open, and the gas enters the housing 11. The gas entering the housing 11 can only be discharged through the through groove 28 on the sealing cylinder 27 and the air outlet 14 on the side wall of the housing 11. The user can judge the continuity, uniformity, and control of their breath by observing whether air is ejected from the air outlet 14 at different heights, as well as the strength and stability of the air ejection.

[0042] During training, the first adjustment knob 15 and the second adjustment knob 24 can be adjusted independently at any time without interfering with each other. Users can adjust the parameters in real time according to their own feelings and training feedback, so as to achieve progressive breathing training from beginner to professional level.

[0043] After training, stop blowing air. Under the action of spring 21, top block 22 returns to the sealing state of sealing ring 23 to prevent external dust or foreign objects from entering the device.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
