Description

Technical Field

[0001] This application relates to the field of voice training bottle technology, and in particular to a SOVT voice training bottle with precise pressure adjustment. Background Technology

[0002] In vocal music education and voice rehabilitation, semi-closed vocal tract technique (SOVT) vocal training tools are widely used because they effectively improve vocal cord closure and regulate breath balance. Vocal training bottles, as a common SOVT tool, work by creating a semi-closed vocal tract through water resistance, guiding users to establish correct vocalization techniques. Currently, most vocal training bottles on the market are basic water resistance bottles, mainly composed of a bottle body, straw, and cap. They rely on changes in the amount of water inside to adjust resistance, resulting in low technical barriers and limited functionality. While some products are equipped with resistance valves, these are mostly external designs, cumbersome to install, and add extra cost. The resistance levels are often labeled purely numerically without clearly specifying the corresponding training scenarios, making it difficult for users to match them to their needs.

[0003] The closest existing technical solution is the ordinary fixed-resistance voice training bottle, which consists of a cylindrical bottle body, a straw with a fixed aperture, and a sealed cap. In use, the user needs to fill the bottle with a certain amount of water, insert the straw into the water, and blow air through the water layer to create resistance, achieving semi-blocked vocal training. This solution can only adjust the resistance by increasing or decreasing the amount of water in the bottle, thus changing the water layer thickness. This requires repeated emptying of the water and cannot precisely control the resistance value. Some products are equipped with external resistance valves, which are inconvenient to install and costly. The resistance levels are labeled in purely numerical form (1-7), without clearly corresponding to weak or strong mixing training scenarios, making it difficult for users to learn.

[0004] Therefore, how to provide a SOVT training bottle with precise voltage regulation and low usage threshold is an urgent problem to be solved in the existing technology. Summary of the Invention

[0005] The purpose of this application is to provide a SOVT vocal training bottle with precise voltage adjustment, which solves the problems of existing vocal training bottles that cannot be precisely adjusted and have a high barrier to entry for use.

[0006] To achieve the above objectives, this application provides a precisely adjustable SOVT vocal training bottle, comprising a bottle body and a cap that seals with the bottle body. The cap includes a first port, a second port, a pressure regulating valve, and an extension tube. The first port extends to the bottom of the bottle body via the extension tube, and the second port communicates with the bottle body via the pressure regulating valve. The pressure regulating valve includes a valve cavity disposed on the cap and a valve body rotatably connected to the valve cavity. The valve cavity is provided with a connecting hole that communicates with the bottle body. The valve body is provided with a through groove that communicates with the second port and the connecting hole. The width of the through groove gradually contracts or expands along the rotation direction of the valve body to regulate the flow rate entering the connecting hole.

[0007] In some embodiments, a scale groove is provided on the outer side of the bottle body, and a plurality of scale intervals are provided in the scale groove, which are used to indicate the liquid level in the bottle body.

[0008] In some embodiments, a limiting groove is provided on the side of the valve cavity near the connecting hole, and a recess is connected to the side of the limiting groove away from the connecting hole; a limiting block and a protrusion are provided at one end of the valve body near the connecting hole, and when the valve body rotates, the limiting block moves circumferentially in the limiting groove, and the protrusion moves circumferentially in the recess.

[0009] In some embodiments, a knob is provided at one end of the valve body away from the communicating hole, and the knob is provided with anti-slip texture.

[0010] In some embodiments, the extension tube includes a first extension tube and a second extension tube, the first extension tube being located between the first port and the second extension tube and forming an isolation channel with respect to the second port, the second extension tube extending to the bottom of the bottle body, and the tail end of the second extension tube being located below the liquid level inside the bottle body.

[0011] In some embodiments, the tail end of the second extension tube forms an oblique section, which is located below the liquid level inside the bottle, so that the gas entering or exiting the first tube port communicates with the second tube port after passing through the liquid inside the bottle.

[0012] In some embodiments, a main training blowpipe is provided at the end of the first tube opening away from the extension tube, and an atomizing suction tube is provided at the end of the second tube opening away from the pressure regulating valve, wherein the length of the main training blowpipe is greater than the length of the atomizing suction tube.

[0013] In some embodiments, both the main training blowpipe and the atomizing straw are made of silicone material, and sealing rings are provided at the connection between the main training blowpipe and the first opening, and at the connection between the atomizing straw and the second opening.

[0014] In some embodiments, the bottle body has a threaded opening and the cap body has a threaded groove at its opening, and the bottle body and the cap body are threadedly sealed.

[0015] In some embodiments, a sealing gasket is provided inside the cap, and when the bottle body and the cap body are threadedly sealed, the sealing gasket is located above the opening of the bottle body.

[0016] Compared to the aforementioned background technology, the SOVT vocal training bottle with precise pressure adjustment provided in this application includes a bottle body and a cap that seals with the bottle body. The cap includes a first port, a second port, a pressure regulating valve, and an extension tube. The first port extends to the bottom of the bottle body via the extension tube, and the second port communicates with the bottle body via the pressure regulating valve. The pressure regulating valve includes a valve cavity disposed on the cap body and a valve body rotatably connected to the valve cavity. The valve cavity has a connecting hole that communicates with the bottle body. The valve body has a through groove that connects the second port and the connecting hole. The width of the through groove gradually narrows or expands along the rotation direction of the valve body to regulate the flow rate entering the connecting hole. Through the special structure of the pressure regulating valve, the user can precisely adjust the air pressure inside the bottle according to their own training needs, thereby controlling the resistance of airflow through the water layer. This precise pressure regulation mechanism not only avoids the inaccurate resistance changes caused by variations in water volume in traditional vocal training bottles, but also allows users to intuitively understand and record the current training resistance through the setting of scale ranges, facilitating the formulation and adjustment of subsequent training plans. Furthermore, the cooperative design of the limiting groove and limiting block, as well as the protrusions and concave parts on the valve body, ensures the stability of the valve body during rotation, preventing pressure regulation failure due to excessive rotation or misoperation, further enhancing the product's safety and reliability.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] Based on the technical problems existing in the background technology, such as Figures 1 to 5As shown in the embodiment of this application, a SOVT (Sound Adjustable Vocal Training) bottle with precise pressure adjustment is provided, including a bottle body 1 and a cap 2 that is sealed to the bottle body 1. The cap 2 includes a first port 21, a second port 22, a pressure regulating valve 23, and an extension tube 24. The first port 21 extends to the bottom of the bottle body 1 through the extension tube 24, and the second port 22 is connected to the bottle body 1 through the pressure regulating valve 23. The pressure regulating valve 23 includes a valve cavity 231 disposed on the cap 2 and a valve body 232 rotatably connected to the valve cavity 231. The valve cavity 231 is provided with a connecting hole 233, which is connected to the bottle body 1. The valve body 232 is provided with a through groove 234 connecting the second port 22 and the connecting hole 233. The width of the through groove 234 gradually contracts or expands along the rotation direction of the valve body 232 to regulate the flow rate entering the connecting hole 233.

[0024] Specifically, such as Figure 1 As shown, the bottle body 1 is made of food-grade PET material. The first port 21, the second port 22, and the pressure regulating valve 23 are integrated on the cap body 2. The extension tube 24 is detachably connected to the first port 21 by plug-in or threaded connection, ensuring that the extension tube 24 extends to the bottom of the bottle body 1. The tail end of the extension tube 24 is located below the liquid surface inside the bottle body 1. It should also be noted that the tail end of the extension tube 24 is located above the center of the bottom of the bottle body 1, ensuring that the gas discharged through the extension tube 24 can be evenly dispersed, reducing interference with vocal training.

[0025] like Figure 3 , 4 As shown in Figure 5, a valve cavity 231 is provided on one side of the cap 2. A valve body 232 is rotatably connected inside the valve cavity 231. A connecting hole 233 is provided inside the valve cavity 231, and the connecting hole 233 communicates with the inside of the bottle 1. The valve body 232 is a cylindrical structure with one end open. A through groove 234 is provided on the side of the end of the valve body 232 located inside the valve cavity 231. The through groove 234 is an irregular groove that is wide at one end and narrow at the other end. The width of the groove gradually decreases from the wider end to the narrower end, and the direction of the groove width contraction is consistent with the direction of rotation of the valve body 232. It should be noted that the maximum width of the wider end of the channel 234 is the same as the diameter of the second port 22. When blowing air, the gas passing through the connecting hole 233 passes through the channel 234 and is discharged through the second port 22. When the valve body 232 is rotated, the overlapping area (flow area) of the channel 234 and the second port 22 changes continuously. That is, at the wider end, the overlapping area of ​​the channel 234 and the second port 22 is the same as the port area of ​​the second port 22. At this time, the airflow is at its maximum and the pressure inside the bottle 1 is at its minimum. As the valve body 232 rotates, the width of the channel 234 narrows, and its overlapping area with the second port 22 decreases. Under the premise that the port area of ​​the second port 22 remains unchanged, the airflow decreases and the pressure inside the bottle 1 increases. At the narrower end, the overlapping area of ​​the channel 234 and the second port 22 is at its minimum, the airflow is at its minimum, and the pressure inside the bottle 1 is at its maximum.

[0026] When in use, due to the change in the flow area of ​​the through groove 234, the pressure inside the bottle 1 decreases as the flow area increases. When in use, the user can rotate the valve body 232 as needed to achieve precise pressure adjustment.

[0027] In some embodiments, a scale groove 11 is provided on the outer side of the bottle body 1, and a plurality of scale intervals 12 are provided in the scale groove 11, which are used to indicate the liquid height in the bottle body 1.

[0028] Specifically, such as Figure 2 As shown, the scale range 12 is set to three ranges, from bottom to top: "Soft", "Balance", and "Power". Compared with the existing digital ranges, this range setting is more convenient to operate. Together with the pressure regulating valve 23, it can achieve precise pressure regulation while lowering the barrier to entry for users.

[0029] It should be noted that the liquid level inside bottle 1 can be clearly seen in at least the 12th graduation section.

[0030] In some embodiments, the valve cavity 231 is provided with a limiting groove 235 on the side near the connecting hole 233, and the limiting groove 235 is connected to a recess 236 on the side away from the connecting hole 233; the valve body 232 is provided with a limiting block 237 and a protrusion 238 at one end near the connecting hole 233. When the valve body 232 rotates, the limiting block 237 moves circumferentially in the limiting groove 235, and the protrusion 238 moves circumferentially in the recess 236.

[0031] like Figure 3 , 4As shown in Figure 5, in order to ensure the stability and sealing of the valve body 232 rotation, a limiting groove 235 and a recess 236 are provided in the valve cavity 231, and a limiting block 237 and a protrusion 238 are provided on the valve body 232. The limiting block 237 cooperates with the limiting groove 235 to ensure the stability and sealing of the rotation, and the recess 236 and the protrusion 238 cooperate to ensure that the through groove 234 can normally connect the second pipe port 22 and the connecting hole 233.

[0032] In some embodiments, a knob 239 is provided at one end of the valve body 232 away from the connecting hole 233, and the knob 239 is provided with anti-slip texture.

[0033] like Figure 5 As shown, the knob 239 protrudes from the cover 2 and is provided with anti-slip texture to facilitate adjustment of the angle of the through groove 234 for precise pressure regulation.

[0034] In some embodiments, the extension tube 24 includes a first extension tube 241 and a second extension tube 242. The first extension tube 241 is located between the first port 21 and the second extension tube 242 and forms an isolation channel with respect to the second port 22. The second extension tube 242 extends to the bottom of the bottle body 1, and the tail end of the second extension tube 242 is located below the liquid level inside the bottle body 1.

[0035] like Figure 1 and 3 As shown, the first extension tube 241 adopts an S-shaped structure, connecting the first tube opening 21 and the second extension tube 242. This structure makes the layout of the first tube opening 21 and the second tube opening 22 more compact and easy to carry. At the same time, it ensures that when blowing, the gas enters the bottle body 1 in the order of "first tube opening 21, first extension tube 241, second extension tube 242, liquid" and then connects with the second tube opening 22 to ensure the vocal training effect.

[0036] In some embodiments, the tail end of the second extension tube 242 forms an oblique section 243, which is located below the liquid level inside the bottle 1, so that the gas entering and exiting the first tube 21 communicates with the second tube 22 after passing through the liquid inside the bottle 1.

[0037] like Figure 3 As shown, the oblique section 243 is designed to prevent air from being unable to escape when the second extension tube 242 is in complete contact with the bottom of the bottle body 1, thus further ensuring the vocal training effect.

[0038] In some embodiments, the first port 21 is provided with a main training blowpipe 211 at the end away from the extension tube 24, and the second port 22 is provided with an atomizing suction tube 221 at the end away from the pressure regulating valve 23, and the length of the main training blowpipe 211 is greater than the length of the atomizing suction tube 221.

[0039] like Figure 1-3 As shown, the external main training blowpipe 211 mainly serves as a blowing training tool. When hot water is added to the bottle 1, the external atomizing straw 221 mainly atomizes the vocal cords with water vapor through reverse suction, and carries it into the vocal tract with the airflow to achieve throat moisturization and soothing.

[0040] Preferred, such as Figure 6 , 7 As shown, an external wide mouthpiece 25 is also fitted onto the main training blowpipe 211. The external wide mouthpiece 25 is made of silicone and includes a wide mouthpiece 251 and a connecting part 252. The connecting part 252 is a tubular structure that can be fitted onto the outside of the main training blowpipe 211. The wide mouthpiece 251 is a flat tubular structure that tapers slightly inward in the middle, conforming to the contour of the lips, relaxing the mouth muscles, and ensuring that the user's lips do not feel any contact during vocal training. This avoids vibration of the oral cavity and lips due to the unsuitable softness or hardness of the blowpipe, which in turn affects the vibration frequency of the vocal cords and prevents air leakage or uneven vibration.

[0041] In some embodiments, both the main training blowpipe 211 and the atomizing straw 221 are made of silicone material, and sealing rings are provided at the connection between the main training blowpipe 211 and the first port 21, and at the connection between the atomizing straw 221 and the second port 22.

[0042] In some embodiments, the bottle body 1 has a threaded opening and the cap 2 has a threaded groove at its opening, and the bottle body 1 and the cap 2 are threadedly sealed.

[0043] like Figure 3 and 4 As shown, the bottle body 1 and the cap body 2 adopt a threaded sealing structure to achieve quick disassembly and installation.

[0044] In some embodiments, a sealing gasket is provided inside the cap 2, and when the bottle 1 and the cap 2 are threadedly sealed, the sealing gasket is located above the opening of the bottle 1.

[0045] The use of sealing gaskets further enhances the overall sealing performance, ensuring optimal vocal training results.

[0046] The above provides a detailed description of the SOVT (Sound Adjustable Voltage) vocal training bottle with precise voltage adjustment provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
