The existing oral muscle training device usually adopts spring, air cushion or elastic component as resistance source, through the structural design of upper and lower bite plates, so that the patient resists the preset resistance when performing the bite action, to achieve the training purpose. However, although such devices can meet certain rehabilitation needs in basic functions, there are still obvious limitations in the flexible adjustment of training intensity.

[0003] Specifically, the existing oral muscle training device often relies on fixed spring or pneumatic element when realizing intensity adjustment, and its adjustment mode is mostly mechanical or manual intervention, resulting in limited adjustment range and insufficient precision, making it difficult to adjust in real time and continuously according to individual differences of patients. Although some devices are provided with adjustment mechanism, its structure is complex and inconvenient to disassemble, which is not conducive to medical staff or patients to flexibly replace or adjust resistance parameters according to rehabilitation progress. In addition, the existing adjustment mechanism lacks intuitive operation feedback, so that the control of training intensity is not accurate enough, affecting the rehabilitation effect and use experience. Such inflexible and inaccurate adjustment mode makes the training device difficult to adapt to individual needs of different patients, limiting the further improvement of rehabilitation effect. In view of the above problems, the existing technology needs to be improved. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0024] The technical solutions in the present application will be described in detail below with reference to the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. The components of the present application described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0025] It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0026] The oral muscle trainer is used to improve the chewing, swallowing and pronunciation functions of patients with swallowing disorders and reduced oral muscle function by providing controllable resistance. Traditional trainers mostly use fixed springs or air cushions as resistance sources, which have obvious limitations: most of the adjustment methods are mechanical intervention, which results in limited adjustment range and insufficient precision, making it difficult to achieve continuous adjustment according to individual differences. The existing adjustment mechanism is complex, inconvenient to operate, and lacks intuitive feedback, affecting the training effect and user experience.

[0027] To this end, the present application proposes an adjustable oral muscle trainer, which uses a V-shaped torsion spring 31 as the core resistance source and ingeniously designs a movable installation method of the bite plate 41 on the force arm of the V-shaped torsion spring 31, supplemented by a locking mechanism 37, thereby realizing continuous and intuitive adjustment of the bite resistance, greatly improving the convenience and adaptability of use.

[0028] The adjustable oral muscle trainer of the present embodiment is characterized in that the bite resistance is adjusted by changing the effective arm length of the bite plate 41 on the force arm of the V-shaped torsion spring 31. The V-shaped torsion spring 31 is an elastic element capable of providing torque, which has an upper force arm 311 and a lower force arm 312 that can rotate relative to each other. The support shaft 3 is the rotation center of the V-shaped torsion spring 31, and the upper force arm 311 and the lower force arm 312 rotate around the support shaft 3 to generate torsion. The bite plate 41 includes an upper bite plate 411 and a lower bite plate 412, which are the parts that contact the patient's mouth and provide the bite surface during training. The locking mechanism 37 is a device for fixing the positions of the upper bite plate 411 and the lower bite plate 412 on the force arm, ensuring the stability of the training resistance.

[0029] Specifically, referring to Figures 1 to 3 The adjustable oral muscle trainer of the present embodiment includes a V-shaped torsion spring 31, a support shaft 3, a bite plate 41, and a locking mechanism 37.

[0030] The V-shaped torsion spring 31 is the core resistance component of the trainer, which is designed to have an upper force arm 311 and a lower force arm 312 that can rotate relative to each other, capable of providing stable torque output.

[0031] The support shaft 3 is the rotation center of the V-shaped torsion spring 31, and the upper force arm 311 and the lower force arm 312 rotate around the support shaft 3 to generate resistance during the bite action.

[0032] The upper bite plate 411 and the lower bite plate 412 are movably arranged along the length direction of the upper force arm 311 and the lower force arm 312, respectively. When the upper bite plate 411 and the lower bite plate 412 slide towards the torsion center of the V-shaped torsion spring 31 (i.e. the support shaft 3), the effective arm length becomes shorter, and according to the mechanical principle of "resistance moment = force x force arm", the bite resistance acting on the bite plate 41 will increase under the condition of constant torque; on the contrary, when the upper bite plate 411 and the lower bite plate 412 slide away from the torsion center, the effective arm length becomes longer, and the bite resistance will decrease. This design allows the trainer to provide continuous and fine resistance adjustment.

[0033] The locking mechanism 37 is used to fix the upper bite plate 411 and the lower bite plate 412 at a specific position on the upper and lower force arms 311 and 312 of the V-shaped torsion spring 31, respectively. The arrangement of the locking mechanism 37 ensures that the position of the bite plate 41 will not move accidentally during the training process, thereby ensuring the stability of the training resistance. The locking mechanism 37 can be implemented in various ways, such as mechanical locking methods such as bolt fixation, buckle locking, and latch fixation. In a simple implementation, a series of holes can be opened on the force arm, and a latch that cooperates with the holes is provided on the bite plate 41, and the position of the bite plate 41 is fixed by inserting the latch.

[0034] Compared with traditional oral muscle trainers, the adjustable oral muscle trainer of the present embodiment has significant advantages. Traditional trainers mostly use fixed springs or pneumatic elements, and the adjustment range is limited, making it difficult to achieve personalized and continuous resistance adjustment. By changing the effective force arm length of the bite plate 41 on the force arm of the V-shaped torsion spring 31, the present embodiment achieves continuous adjustment of resistance, and the adjustment process is intuitive and convenient without the need to replace any parts. This innovative design greatly improves the adaptability and user experience of the trainer, allowing medical personnel or patients to flexibly adjust the training intensity according to the progress of rehabilitation.

[0035] To further optimize the movement and fixation of the bite plate, please refer to Figure 3 and Figure 5 The present application proposes an improved scheme, that is, in the adjustable oral muscle trainer, a horizontal extension frame 35 is arranged along the upper and lower force arms 311 and 312, and the upper and lower bite plates 411 and 412 are movably sleeved on the horizontal extension frame 35 through a telescopic sleeve 36, respectively.

[0036] The horizontal extension frame 35 refers to a rod-shaped or strip-shaped structure extending along the length direction of the upper and lower force arms 311 and 312, and its main function is to provide stable guidance and support for the movement of the upper and lower bite plates 411 and 412. The telescopic sleeve 36 is a sleeve structure that is sleeved on the horizontal extension frame 35 and can move along the length direction thereof. The telescopic sleeve 36 is connected with the upper and lower bite plates 411 and 412, so that the bite plates can slide with the telescopic sleeve 36 on the horizontal extension frame 35. The inner diameter of the telescopic sleeve 36 cooperates with the outer dimensions of the horizontal extension frame 35 to ensure smooth sliding without obvious shaking.

[0037] The scheme of the present application effectively solves the problems of insufficient stability and inconvenient adjustment that may exist during the movement of the upper and lower bite plates 411 and 412 by introducing the horizontal extension frame 35 and the telescopic sleeve 36.

[0038] In some preferred embodiments, the horizontal extension 35 can be designed as two parallel guide rods, respectively fixed on the upper and lower force arms 311 and 312. The upper and lower bite plates 411 and 412 are then respectively sleeved on the corresponding guide rods through two telescopic sleeves 36. In addition, the surface of the horizontal extension 35 can be polished or coated with a friction-reducing material to further improve the sliding performance. When it is necessary to adjust the position of the bite plates, the user only needs to push or pull the bite plates slightly to make them move smoothly on the horizontal extension 35 to the desired position.

[0039] Further, please refer to Figure 3 and Figure 4 , the present application proposes a locking mechanism 37 comprising a plug-in column 373; the horizontal extension 35 is provided with a plurality of adjustment holes 372, and the telescopic sleeve 36 is provided with fixing holes 371 matched with the adjustment holes 372; the plug-in column 373 can be plugged into the fixing hole 371 and any adjustment hole 372.

[0040] Among them, the locking mechanism 37 refers to the device used to fix the upper and lower bite plates 411 and 412 on the corresponding upper and lower force arms 311 and 312 respectively. The plug-in column 373 is usually cylindrical or has other suitable geometric shapes, and its size is designed to be able to tightly match the fixing hole 371 and the adjustment hole 372, so as to realize reliable locking. The plurality of adjustment holes 372 provided on the horizontal extension 35 are arranged at equal intervals or non-equal intervals along the length direction, which are used to provide locking selection at different positions, so as to realize fine adjustment of the position of the bite plate. The fixing hole 371 provided on the telescopic sleeve 36 is a hole matched with the plug-in column 373, which can be aligned with a certain adjustment hole 372 on the horizontal extension 35 when the telescopic sleeve 36 moves to the desired position. The plug-in column 373 can be plugged into the fixing hole 371 and any adjustment hole 372, which means that the plug-in column 373 can pass through the fixing hole 371 on the telescopic sleeve 36 and the adjustment hole 372 on the horizontal extension 35 at the same time, so as to lock the telescopic sleeve 36 (and the bite plate fixed thereon) at a certain position.

[0041] The scheme of the present application provides stable physical locking by introducing the cooperation of the plug-in column 373, the adjustment hole 372 and the fixing hole 371, which utilizes the tight cooperation between the hole and the column, so as to ensure that the position of the bite plate will not accidentally slide or deviate during the training process. Therefore, the trainer can provide accurate and repeatable bite plate position setting according to the specific needs of the user, greatly improving the stability and effectiveness of the training.

[0042] Further, please refer to Figure 4The locking mechanism 37 is further optimized in the application, and specifically, the locking mechanism 37 further comprises a shell sleeve 375 and a tension spring 374; the plug-in column 373 is arranged in the shell sleeve 375, and the tension spring 374 is connected to the plug-in column 373 and the shell sleeve 375, and is used to drive the plug-in column 373 to be inserted into the fixing hole 371 and the adjusting hole 372.

[0043] The shell sleeve 375 can be a hollow structure made of plastic or metal, which mainly provides a guiding and protecting space for the plug-in column 373, and also serves as a mounting base of the tension spring 374. The tension spring 374 is a common elastic element, and its two ends are connected to the plug-in column 373 and the shell sleeve 375 respectively, thereby providing a continuous insertion force for the plug-in column 373.

[0044] Specifically, when the positions of the upper bite plate 411 and the lower bite plate 412 need to be adjusted, the plug-in column 373 is first pulled out of the fixing hole 371 and the adjusting hole 372 against the tension of the tension spring 374. Then, the telescopic sleeve 36 is moved so that the fixing hole 371 thereon is aligned with the adjusting hole 372 on the horizontal extension frame 35. The plug-in column 373 is loosened, and under the action of the tension spring 374, the plug-in column 373 is automatically inserted into the fixing hole 371 and the adjusting hole 372, thereby fixing the telescopic sleeve 36 at the position.

[0045] The scheme of the application realizes the automatic locking function of the plug-in column 373 by adding the shell sleeve 375 and the tension spring 374, thereby ensuring the reliability and stability of the connection between the telescopic sleeve 36 and the horizontal extension frame 35.

[0046] Further, the application provides an improved scheme, please refer to Figure 1 By cooperation of the first rotating sleeve 32, the second rotating sleeve 33 and the third rotating sleeve 34, the positions of the upper bite plate 411 and the lower bite plate 412 are adjustable, thereby improving the applicability of the oral muscle trainer.

[0047] The first rotating sleeve 32 and the third rotating sleeve 34 are used to mount the upper bite plate 411, and the second rotating sleeve 33 is used to mount the lower bite plate 412. Specifically, the horizontal extension frame 35 is arranged on the first rotating sleeve 32, the second rotating sleeve 33 and the third rotating sleeve 34, so that the upper bite plate 411 and the lower bite plate 412 can move along the horizontal extension frame 35, thereby adjusting the positions of the upper bite plate 411 and the lower bite plate 412.

[0048] The scheme of the present application sets the first rotating sleeve shell 32, the second rotating sleeve shell 33 and the third rotating sleeve shell 34, so that the upper bite plate 411 and the lower bite plate 412 can move along the horizontal extension frame 35, thereby adjusting the positions of the upper bite plate 411 and the lower bite plate 412, solving the problem that the positions of the upper bite plate 411 and the lower bite plate 412 are not easy to adjust, and improving the applicability of the oral muscle trainer.

[0049] In the above-mentioned embodiments of the present application, the V-shaped torsion spring 31 can adopt various forms, but ordinary torsion springs may have torsion attenuation after long-term use, affecting the stability of the training effect. For this purpose, please refer to Figure 5 , the present application proposes a scheme that the V-shaped torsion spring 31 is a double torsion spring, in order to improve the durability and stability of the spring.

[0050] Among them, the double torsion spring refers to a spring structure composed of two or more torsion springs in parallel. Specifically, the double torsion spring can be composed of two torsion springs with the same or different torsion coefficients, and the two torsion springs are arranged side by side and jointly bear the torsional load.

[0051] The scheme of the present application adopts a double torsion spring as the V-shaped torsion spring 31, which can effectively disperse the torsional load and reduce the stress concentration of a single spring, thereby slowing down the fatigue and wear of the spring and prolonging the service life. At the same time, the design of the double torsion spring can improve the overall torsional stiffness, so that the oral muscle trainer can maintain stable resistance output during long-term use and ensure the consistency of the training effect.

[0052] In some cases, the user may need to temporarily fix the bite plate in order to perform other operations or rest. For this purpose, please refer to Figure 6 , the present application further proposes the structure of the fixing seat 4 and the plug plate 43, which realizes the fixation of the bite plate through the cooperation of the plug plate 43 and the insertion slot 42 on the fixing seat 4.

[0053] Among them, the fixing seat 4 can be made of plastic, metal or other materials, and its main function is to provide a stable support structure and is provided with an insertion slot 42 for accommodating and fixing the plug plate 43. The size and shape of the insertion slot 42 should match the plug plate 43 to ensure that the plug plate 43 can be stably inserted and fixed. The plug plate 43 provided on the upper bite plate 411 and the lower bite plate 412 is adapted in size and shape to the insertion slot 42 on the fixing seat 4, thereby realizing reliable connection with the fixing seat 4.

[0054] The scheme of the present application realizes the quick fixation and release of the bite plate by opening the insertion slot 42 on the fixing seat 4 and providing the plug plate 43 on the upper bite plate 411 and the lower bite plate 412, which is simple in structure and convenient to operate, and can meet the needs of the user in different scenarios.

[0055] As a specific implementation, the fixed seat 4 can be arranged outside the trainer housing 1, or integrated inside the trainer housing 1. The number of slots 42 can be adjusted according to actual needs, and one slot 42 can be arranged, or multiple slots 42 can be arranged to accommodate different sizes and shapes of the plugboard 43.

[0056] In the scheme of the present application, the upper bite plate 411 and the lower bite plate 412 are directly in contact with the user's teeth, and the design of their surfaces directly affects the user's comfort and training effect. For this purpose, please refer to Figure 6 , the present application is provided with upper and lower tooth grooves on the opposite surfaces of the upper bite plate 411 and the lower bite plate 412. Through the structural design of the tooth grooves, the user's teeth can be better fitted, and the comfort and effect of the training can be improved.

[0057] Among them, the upper and lower tooth grooves refer to the recessed structures formed on the surfaces of the upper bite plate 411 and the lower bite plate 412, which are adapted to the shape of the teeth. Specifically, the upper tooth groove can be designed to match the shape of the upper teeth, and the lower tooth groove can be designed to match the shape of the lower teeth.

[0058] Further, please refer to Figure 1 , the present application proposes an improved scheme, that is, to add a trainer housing 1, and to arrange the V-shaped torsion spring 31 and the support shaft 3 in the trainer housing 1, so as to provide a stable working environment for the V-shaped torsion spring 31 and the support shaft 3, and improve the reliability and durability of the oral muscle trainer.

[0059] Among them, the trainer housing 1 refers to the external protective structure of the oral muscle trainer, which mainly protects the internal V-shaped torsion spring 31 and support shaft 3 from external impact, dust and moisture. The material of the trainer housing 1 can be plastic, metal or other materials with sufficient strength and durability. The shape of the trainer housing 1 can be designed according to actual needs.

[0060] The V-shaped torsion spring 31 and the support shaft 3 are arranged in the trainer housing 1, which can effectively prevent external factors from affecting the V-shaped torsion spring 31 and the support shaft 3, and ensure their normal work. In addition, the trainer housing 1 can also absorb external impact, reduce the impact force on the V-shaped torsion spring 31 and the support shaft 3, thereby prolonging their service life.

[0061] On the basis of the above-mentioned embodiments of the present application, in order to improve the user experience of the oral muscle trainer, please refer to Figure 1 , the present application provides an optimized scheme, that is, to arrange a hand-held handle 2 on the trainer housing 1, so as to make the user hold the trainer more stably and comfortably, thereby improving the convenience and effect of the training.

[0062] The hand-held handle 2 refers to a structure design convenient for the user to hold, and its specific shape, size and material can be optimized according to the principle of ergonomics to provide the best holding feeling.

[0063] As a specific embodiment, the hand-held handle 2 can be designed in one piece with the trainer shell 1, or can be designed to be detachable for replacement or cleaning. The position of the hand-held handle 2 can be adjusted according to the user's habits, for example, it can be arranged on the side or top of the trainer shell 1.

[0064] The above only describes the embodiments of the present application and is not used to limit the protection scope of the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
