Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an oral muscle trainer. Background Technology

[0002] Abnormalities in the development or function of the maxillofacial muscles can affect the force balance between the jawbone and teeth, and are a common cause of dentofacial deformities. Through myofunctional therapy, the forces between muscles, jawbone, and teeth can be coordinated, preventing, blocking, or correcting the occurrence and development of malocclusion. This simplifies orthodontic treatment, improves treatment outcomes, and enhances the long-term stability of orthodontic treatment.

[0003] Common muscle function training methods in existing technologies include: ① Paper strip swishing: The patient holds one end of a long paper strip in their mouth and gradually pulls the entire strip into their oral cavity using the strength of their lip muscles. ② Button pulling: Thread a string through a button and place it in the patient's vestibular sulcus. Pull the button outward with appropriate force, several times in the center and left / right directions. The patient uses the strength of their lip muscles to hold the button in place and prevent it from being pulled out. ③ Paper strip pulling: Take a smooth, soft piece of paper of suitable size and thickness, firmly clamp one end between the upper and lower lips, leaving the other end outside the mouth; pinch the part outside the mouth with your fingers and pull forcefully while keeping your lips tightly closed until the paper is pulled out. ④ Blowing paper strip: The patient holds the paper strip in their mouth and tries to blow it while keeping their lips tightly closed. ⑤ Pulling corners of the mouth: Use the little fingers of both hands to pull the corners of the mouth, causing the lips to contract and close. Practice repeatedly, morning and evening, until the muscles are fatigued. ⑥ Cheek puffing and blowing. ⑦ Whistling. Through the different training methods mentioned above, the muscles in different parts of the oral cavity can be trained to guide the normal growth and development of the maxillofacial region, and promote the normal development of the craniofacial structure and the coordinated and stable function of the stomatognathic system.

[0004] However, the above methods have the following drawbacks:

[0005] 1. Existing oral muscle trainers have limited functionality and can only perform one type of muscle training. They cannot perform different intensities of exhalation and inhalation-related muscle function training through the same air inlet. Even if the same air inlet and outlet are used for exhalation and inhalation training, it is impossible to distinguish between exhalation and inhalation movements, making it impossible to monitor the user's oral muscle training.

[0006] 2. Existing training methods cannot accurately quantify or adjust the intensity of training. For example, the force used to pull a button or the hardness of chewing gum may result in insufficient training intensity and failure to achieve the best therapeutic effect. Summary of the Invention

[0007] The purpose of this application is to provide an oral muscle trainer to solve the problems in the prior art that make it impossible to complete different intensities of respiratory and inspiratory muscle function training through the same airway, and that training intensity cannot be quantified or adjusted.

[0008] The embodiments of this application can be implemented through the following technical solutions:

[0009] An oral muscle trainer includes a chamber, one end of which is provided with an airflow interface for delivering gas exhaled or inhaled from the mouth of a wearer. The chamber contains a training component that divides the airflow path within the chamber into an exhalation channel and an inhalation channel with the same or different damping forces. The training component switches the gas to flow in the exhalation channel or inhalation channel with different flow paths according to the direction of the airflow, so that the flow rate of equal amounts of gas flowing in the exhalation channel or inhalation channel is the same or different.

[0010] The damping force within the expiratory and inspiratory channels is adjustable.

[0011] Furthermore, the chamber also includes sensors respectively disposed in the expiratory channel and the inspiratory channel, the sensors being used to identify the airflow pressure in the expiratory channel or the inspiratory channel.

[0012] Furthermore, the training component is a resistance adjustment structure with a flexible paddle, and the training component includes an airflow adjustment component and a diaphragm, wherein the diaphragm is a flexible resistance adjustment paddle;

[0013] The airflow regulating component includes a gas flow channel and a partition block disposed in its middle. The gas flow channel extends toward the airflow interface, and the partition block is connected to the middle of the gas flow channel and divides the gas flow channel into a first channel and a second channel.

[0014] The middle part of the diaphragm is connected to the separator block, and the two ends are respectively limited to the lower and upper parts of the gas flow channel by limiting steps. The flow resistance in the first channel and the second channel is different.

[0015] Furthermore, the limiting step is disposed below the partition block. The limiting step includes a first step and a second step. The first step is a convex surface disposed inside the first channel and facing the center of the gas flow channel. The second step is a concave surface disposed inside the second channel and facing away from the center of the gas flow channel.

[0016] The middle part of the diaphragm is fixedly connected to the lower part of the separator block, and the two ends are respectively movably connected to the upper part of the first step and the lower part of the second step.

[0017] The first channel is used as an inhalation channel, and the second channel is used as an exhalation channel.

[0018] Furthermore, the training assembly also includes a base plate, the airflow adjustment assembly is connected to the base plate, and two sensors are connected to the side of the base plate facing the airflow adjustment assembly;

[0019] The airflow regulating assembly also includes a connecting block located between the two sensors and connected between the base plate and the separator. The middle part of the diaphragm is fixedly connected to the lower part of the separator via the connecting block, thus separating the first channel and the second channel into two independent channels.

[0020] Furthermore, the chamber is formed by interconnecting a first tube, a second tube, and a third tube, with a first opening and a second opening respectively provided at both ends of the first tube;

[0021] The second tube extends along the axial direction of the first tube and its two ends are radially connected to the first opening and the second opening on the side of the first tube. One end of the third tube is radially connected to the third opening on the side of the first tube, and the other end is open. The third opening is located between the first opening and the second opening. The flow resistances of the second tube and the third tube are different.

[0022] The training component includes a resistance plug that is slidably connected to the cavity of the first tube. The resistance plug is a flexible resistance adjustment block. When the second tube opening is used as the intraoral wearing end of the first tube, the resistance plug is limited to sliding displacement between the second and third openings of the first tube by a limiting step.

[0023] Furthermore, the limiting step includes a first step and a second step, both of which are protrusions disposed on the inner wall of the first tube and extending toward the axis of the first tube.

[0024] The first tube body has a first port and a second port at its two ends respectively. When the first port serves as the airflow interface of the chamber, the first step is located below the second port of the first tube body, that is, at the end adjacent to the second port. The second step is located above the third port of the first tube body, that is, at the end adjacent to the first port.

[0025] The passage from the second opening of the first tube to the first opening through the second tube is used as an inhalation passage, and the passage from the first opening of the first tube to the third tube is used as an exhalation passage.

[0026] Furthermore, the thickness of the resistance plug is L1, the distance from the upper end face of the first step to the upper end face of the second port is L2, and the distance from the upper end face of the first step to the lower end face of the third port is L3, where L2 < L1 < L3.

[0027] The distance from the upper end face of the second port to the lower end face of the second step is L4, and the distance from the lower end face of the third port to the lower end face of the second step is L5, where L5 < L1 < L4.

[0028] Furthermore, the chamber is disposed within the trainer, and both ends of the chamber are provided with openings that communicate with the training component;

[0029] The training component includes a forward channel and several resistance channels arranged sequentially along the forward channel. The resistance channels are curved, and both ends of the resistance channels are connected to the forward channel. The two ends of the forward channel are respectively connected to two openings of the chamber.

[0030] Furthermore, one of the ports of the trainer is connected to the air inlet in the cavity of the monitoring device, and the side of the cavity is provided with an air outlet that slides relative to the opening of the side wall of the monitoring device.

[0031] A baffle is provided on the side of the accommodating cavity. The baffle is connected to the side wall where the air outlet is located and is slidably connected to the side wall of the outer shell of the trainer to adjust the gas flow area of ​​the air outlet relative to the opening of the side wall of the monitoring device.

[0032] The oral muscle trainer provided in this application has at least the following beneficial effects:

[0033] This application can complete different training inhalation and exhalation-related muscle training methods with different training intensities using a single device. Moreover, when training oral muscles related to inhalation and exhalation, there is no need to switch between different air vents. It has the advantages of simple structure, multiple functions, and strong practicality.

[0034] This application utilizes a training component to perform exhalation and inhalation training under different pathways. This allows for the differentiation of exhalation and inhalation movements even when using the same inlet and outlet for exhalation and inhalation training. Furthermore, sensors monitor the user's oral muscle training status, facilitating accurate quantification of the training progress in the future.

[0035] This application allows for training at different intensities by adjusting or replacing training components with different parameters, effectively avoiding the inability to achieve optimal therapeutic results due to insufficient training intensity.

[0036] This application can be used not only as an oral muscle trainer, but also as a lip muscle trainer and a respiratory muscle trainer, and has the advantages of being versatile and having a wide range of applications. Attached Figure Description

Those skilled in the art will understand the specific meanings of the above terms within the context of this application.

[0056] Example 1

[0057] Figure 1 This is a schematic diagram of the overall structure of an oral muscle trainer according to this embodiment. Figure 2 This is a schematic diagram showing the exploded state of an oral muscle trainer according to this embodiment, as follows: Figure 1 , Figure 2 As shown, an oral muscle trainer includes an extraoral device 1 and an intraoral device 2. The wearer performs oral muscle training related to exhalation and inhalation by wearing the extraoral device 1 connected to the intraoral device 2. The extraoral device 1 includes a bottom shell 13 and a top cover 14, which are connected to form a shell with an internal cavity.

[0058] The chamber contains a training component 12. The top cover 14 has a connection port 141 on the side facing the training component 12. The intraoral device 2 is connected to the extraoral device 1 through the connection port 141. The connection port 141 serves as an airflow interface at one end of the chamber for delivering gas exhaled or inhaled from the wearer's mouth. Correspondingly, the other end of the chamber has an air outlet, so that an airflow passage can be formed within the chamber.

[0059] Furthermore, the training component 12 divides the airflow path within the chamber into an exhalation channel and an inhalation channel with the same or different damping forces. The training component 12 switches the gas flow in the exhalation channel or inhalation channel with different flow paths according to the direction of the airflow, so that the flow speed of the same amount of gas through the airflow interface in the exhalation channel or the inhalation channel is the same or different, so as to achieve the same or different intensities of exhalation training and inhalation training through the same airflow hole. Moreover, the intensity of exhalation training and inhalation training can be adjusted by simply adjusting or replacing different models of the training component 12, so that the damping force in the exhalation channel and the inhalation channel is adjustable.

[0060] Furthermore, the chamber also includes sensors 124 respectively disposed in the expiratory channel and the inspiratory channel, such as... Figure 3 As shown, the gas flow rate is detected by the sensors 124 in each channel to obtain the training situation, thereby distinguishing whether the training is exhalation training or inhalation training, and quantifying the intensity of exhalation training and inhalation training.

[0061] Specifically, such as Figure 3 , Figure 4 As shown, the training component 12 is a resistance adjustment structure with a flexible paddle. The training component 12 includes an airflow adjustment component 121 and a diaphragm 122. The diaphragm 122 is a flexible resistance adjustment piece, which is used to provide resistance to the gas flowing in the airflow adjustment component 121.

[0062] The airflow regulating assembly 121 includes a gas flow channel 1210 and a partition block 1213 disposed in its middle. The gas flow channel 1210 extends toward the airflow interface, and the partition block 1213 is connected to the middle of the gas flow channel 1210 to divide the gas flow channel 1210 into a first channel 1211 and a second channel 1212.

[0063] The diaphragm 122 is adapted to the shape of the gas flow channel 1210. The middle part of the diaphragm 122 is connected to the partition block 1213, and the two ends are respectively limited above and below the gas flow channel 1210 by limiting steps. The diaphragm 122 located in the first channel 1211 and the diaphragm 1212 located in the second channel 1212 have different flexibility strengths, so that the diaphragm 122 can not only switch the opening and closing of the first channel 1211 and the second channel 1212 according to the direction of airflow, but also make the airflow in the first channel 1211 and the second channel 1212 experience different resistances.

[0064] In some preferred embodiments, the diaphragm 122 is a flexible material with a certain degree of hardness, so that the diaphragm 122 can naturally unfold within the gas flow channel 1210 when no force is applied, and can deform under the action of force.

[0065] In some preferred embodiments, the diaphragm 122 may also have its rigidity increased by other rigid components, such as an internal metal sheet or an internal current-carrying conductor. The rigidity of the current-carrying conductor increases when energized and decreases when de-energized, so that the diaphragm 122 can naturally expand within the gas flow channel 1210 when no force is applied and can deform under the action of force.

[0066] In some preferred embodiments, by adjusting the thickness, shape, density, etc. of the diaphragm 122 located in the first channel 1211 and the second channel 1212, the airflow resistance in the first channel 1211 and the second channel 1212 can be made different.

[0067] In some preferred embodiments, the resistance encountered by the gas flowing through the first channel 1211 and the second channel 1212 can be changed by adjusting the cross-sectional areas of the first channel 1211 and the second channel 1212 to different sizes. Specifically, the limiting step is disposed below the separator block 1213. The limiting step includes a first step 1214 and a second step 1215. The first step 1214 is a step surface disposed inside the first channel 1211 and protruding towards the center of the gas flow channel 1210. The second step 1215 is a step surface disposed inside the second channel 1212 and concave away from the center of the gas flow channel 1210. This allows the limiting step to not only limit the diaphragm 122 but also adjust the cross-sectional areas of the first channel 1211 and the second channel 1212 to different sizes.

[0068] In some preferred embodiments, the middle part of the membrane 122 is fixedly connected to the lower part of the separator 1213, and the two ends are respectively movably connected to the upper part of the first step 1214 and the lower part of the second step 1215. In this case, the first channel 1211 is used as an inhalation channel and the second channel 1212 is used as an exhalation channel.

[0069] In some preferred embodiments, to facilitate the replacement and installation of the diaphragm 122, the airflow regulating assembly 121 further includes a connecting block 1216. The middle part of the diaphragm 122 is fixedly connected to the lower part of the partition block 1213 via the connecting block 1216. The connecting block 1216 and the partition block 1213 can be detachably connected by mutually cooperating bolts and nuts or mutually cooperating buckles and slots.

[0070] In some preferred embodiments, the training component 12 further includes a base plate 120, the airflow adjustment component 121 is connected to the base plate 120, and the sensor 124 is connected to the side of the base plate 120 facing the airflow adjustment component 121. In order for each sensor 124 to accurately detect the airflow pressure in its corresponding channel, two sensors 124 are provided. The connecting block 1216 is located between the two sensors 124 and connected between the base plate 120 and the separator block 1213, which is used to set the first channel 1211 and the second channel 1212 as two independent channels. The two sensors 124 are respectively arranged in the first channel 1211 and the second channel 1212, so as to monitor the airflow in the first channel 1211 and the second channel 1212 respectively without interference.

[0071] The following is a detailed description of an oral muscle trainer according to a specific application scenario:

[0072] By adjusting the flexibility strength of the diaphragm 122 located in the first channel 1211 and the second channel 1212 to a parameter, or by setting the cross-sectional area in the first channel 1211 and the second channel 1212 to a size, the first channel 1211 and the second channel 1212 are pre-configured as flow channels with the same or different damping forces.

[0073] The outer end of the intraoral device 2 is connected to the connection port 141 of the external device 1. The wearer holds the inner end of the intraoral device 2 in their mouth. In the direction of airflow during the wearer's inhalation and exhalation, when inhaling, the diaphragm 122 in the first channel 1211 is open under the pressure of the gas, while the diaphragm 122 in the second channel 1212 is closed because it is limited by the second step 1215. At this time, the first channel 1211 serves as the inhalation channel. The sensor 124 in the first channel 1211 detects the corresponding pressure and feeds back information to the terminal.

[0074] Conversely, during exhalation, under the reverse pressure of the gas, the diaphragm in the second channel 1212 is open, while the diaphragm 122 in the first channel 1211 is closed because it is limited by the first step 1214. At this time, the second channel 1212 serves as the exhalation channel, and the sensor 124 in the second channel 1212 identifies the corresponding pressure and sends the information back to the terminal.

[0075] The above oral muscle training methods not only allow for different intensities of expiratory and inspiratory muscle function training through the same airway, improving treatment effectiveness, but also enable the use of sensors to monitor the user's oral muscle training, quantify the training intensity, and facilitate adjustments to the training intensity of the next stage based on the treatment progress.

[0076] Example 2

[0077] Figure 5 , Figure 6 These are schematic diagrams of an oral muscle trainer from different perspectives in this embodiment, as shown below. Figure 5 , Figure 6As shown, an oral muscle trainer includes a first tube 31, a second tube 32, and a third tube 33. The second tube 32 extends axially along the first tube 31, and its two ends are radially connected to a first port A and a second port B on the side of the first tube 31. One end of the third tube 33 is radially connected to a third port C on the side of the first tube 31, and the other end is open. The third port C connecting the third tube 33 to the first tube 31 is located between the first port A and the second port B of the second tube 32, such that the first tube 31, the second tube 32, and the third tube 33 together constitute a tube assembly with a communicating chamber inside.

[0078] In some preferred embodiments, the first tube 31 is provided with a first port 311 and a second port 312 that are connected to each other at both ends. When the wearer uses the first port 311 as the airflow interface of the chamber by holding it in their mouth, the second port 312 and the third tube 33 serve as the airflow interface of the chamber for air to be released.

[0079] Figure 7 , Figure 8 respectively along different training states Figure 6 A cross-sectional view along the middle AA direction, as shown below. Figure 7 , Figure 8 As shown, the chamber contains a training component 12. The training component 12 includes a resistance plug 125 that is slidably connected to the chamber of the first tube 31. The resistance plug 125 is a resistance adjustment block, which is used to switch the exhalation channel and the inhalation channel in the chamber according to the direction of airflow by changing the position of the resistance plug 125 relative to the first tube 31.

[0080] In some preferred embodiments, the resistance plug 125 is a flexible resistance adjustment block. The resistance plug 125 is interference-fitted with the inner diameter of the first tube 31 so that the resistance plug 125 can seal the second port B or the third port C through its own deformation, ensuring that the gas flow paths are independent of each other during exhalation and inhalation, and that there is no gas leakage when the gas flows in the second tube 32 or the third tube 33.

[0081] In some preferred embodiments, the second tube 32 and the third tube 33 have different diameters. The resistance plug 125 is positioned between the second port B and the third port C of the first tube 31 by a limiting step. As the airflow direction of the first tube 31 changes, the resistance plug 125 slides within the first tube 31 to the second port B or the third port C, thereby closing the flow passage of the second tube 32 or the third tube 33. The resistance plug 125 divides the airflow passage in the chamber into an exhalation channel and an inhalation channel with different damping forces, so that the flow rates of equal amounts of gas flowing through the airflow interface in the exhalation channel and the inhalation channel are different.

[0082] In some preferred embodiments, the diameter, inner wall roughness, or length of the second tube 32 and the third tube 33 can be set to different parameters to achieve different damping forces when equal amounts of gas flow in the second tube 32 and the third tube 33.

[0083] In some preferred embodiments, the limiting step includes a first step 1214 and a second step 1215. Both the first step 1214 and the second step 1215 are protrusions provided on the inner wall of the first tube 31 and extending toward the axis of the first tube 31. The first step 1214 is located below the second opening B of the first tube 31, that is, at one end adjacent to the second opening 312. The second step 1215 is located above the third opening C of the first tube 31, that is, at one end adjacent to the first opening 311.

[0084] Furthermore, the thickness L1 of the resistance plug 125, the distance from the upper end face of the first step 1214 to the upper end face of the second port B is L2, the distance from the upper end face of the first step 1214 to the lower end face of the third port C is L3, L2 < L1 < L3, the distance from the upper end face of the second port B to the lower end face of the second step 1215 is L4, and the distance from the lower end face of the third port C to the lower end face of the second step 1215 is L5, L5 < L1 < L4, so that when the resistance plug 125 closes the second port B, the gas can flow smoothly through the first tube 31 to the third tube 33, and when the resistance plug 125 closes the third port C, the gas can flow smoothly through the first tube 31 to the second pipeline, so that during inhalation and exhalation, the gas flows to different channels under the action of the resistance plug 125.

[0085] In some preferred embodiments, the training component 12 further includes two sets of elastic balance adjustment components. Along the axial direction of the first tube 31, the two sets of balance adjustment components are respectively disposed at both ends of the cavity of the first tube 31 and connected to both ends of the resistance plug 125. The resistance plug 125 is preset between the second port B and the third port C by the elastic adjustment force of the two sets of balance adjustment components, so as not to slide down to the second port B or the third port C under the action of gravity.

[0086] In some preferred embodiments, each of the balance adjustment components includes an elastic body 126 and a fixed connection part 127. The fixed connection part 127 is radially connected to the inner wall of the first tube 31. The two ends of the elastic body 126 are respectively connected to the resistance plug 125 and the fixed connection part 127. The elastic body 126 can be a spring, rubber band, or elastic rope, etc., to ensure the degree of freedom of displacement of the resistance plug 125 under the action of airflow while the elastic body 126 pulls the position of the resistance plug 125.

[0087] like Figure 7 , Figure 8 As shown in the figure, the direction indicated by the arrow represents the direction of gas flow. When the first port 311 serves as the airflow interface of the chamber (i.e., as the intraoral end of the first tube 31), the passage from the second port 312 of the first tube 31 through the second tube to the first port 311 is used as an inhalation channel, and the passage from the first port 311 of the first tube 31 to the third tube 33 is used as an exhalation channel.

[0088] In some preferred embodiments, the second tube 32 and the third tube 33 are respectively provided with sensors 124, which are used to monitor the airflow in the second tube 32 and the third tube 33 respectively without interference.

[0089] Example 3

[0090] Figure 9 This is a three-dimensional structural diagram of an oral muscle trainer according to this embodiment. The oral muscle trainer includes a trainer 41 and a monitoring device 42. The trainer 41 has a chamber, and the chamber contains a training component 12. The two ends of the chamber are respectively provided with a first interface 411 and a second interface 412 communicating with the training component 12, so that an airflow passage is formed in the chamber.

[0091] The training component 12 divides the airflow path in the chamber into an exhalation channel and an inhalation channel with different damping forces. The training component 12 switches the gas to flow in the exhalation channel or inhalation channel with different flow paths according to the direction of the airflow, so that the flow rate of the same amount of gas flowing through the airflow interface in the exhalation channel or the inhalation channel is different.

[0092] Specifically, Figure 10 This is a side view of the trainer 41 in this embodiment. Figure 11 , Figure 12 Different flow downwards Figure 10 A schematic diagram of the cross-sectional structure along the BB direction, as shown below. Figures 10 to 12 As shown, the training component 12 includes a forward channel 128 and several resistance channels 129 arranged sequentially along the forward channel 128. The resistance channels 129 are curved, and both ends of the resistance channels 129 are connected to the forward channel 128. The two ends of the forward channel 128 are respectively connected to the first interface 411 and the second interface 412.

[0093] by Figure 11 , Figure 12 As shown in the example, when the gas flows along Figure 11 As the arrow indicates, when gas flows in from the first interface 411, it flows along the forward channel 128 until it flows out through the second interface 412. When the gas flows along... Figure 12 When the gas flows in from the second interface 412 as indicated by the arrow, it enters the forward channel 128 and the resistance channel 129. The gas in the forward channel 128 and the gas in the resistance channel 129 collide, increasing the gas flow resistance in the forward channel 128 and ensuring that the flow speed is different under different flow paths in different gas flow directions.

[0094] In some preferred embodiments, in order to facilitate the differentiation and quantification of the wearer's inhalation and exhalation actions, sensors can be installed in both the forward channel 128 and the resistance channel 129 to detect the gas flow rate.

[0095] In some preferred embodiments, the damping force of the two channels can be adjusted by changing the diameter or length or wall roughness of each channel of the training component, so as to adjust the training intensity.

[0096] Furthermore, the monitoring device 42 is provided with a accommodating cavity. One end of the accommodating cavity is provided with an air inlet 4211, and the side is provided with an air outlet 4212 that slides relative to the opening of the side wall of the monitoring device 42. The airflow passage of the trainer 41 is connected to the accommodating cavity of the monitoring device 42 through the air inlet 4211. A baffle 4213 is provided on the side of the accommodating cavity. The baffle 4213 is connected to the side wall where the air outlet 4212 is located and is slidably connected to the side wall of the outer shell of the trainer 41. By adjusting the position of the baffle 4213 relative to the side wall of the outer shell, the gas flow area of ​​the air outlet 4212 relative to the opening of the side wall of the monitoring device 42 is adjusted. In this way, the gas flow speed in the trainer 41 can be adjusted by adjusting the gas flow speed in the accommodating cavity, thereby adjusting the training intensity.

[0097] Specifically, Figure 13 This is a schematic diagram showing the disassembled state of the monitoring device 42 in this application, as shown below. Figure 13 As shown, with Figure 13 Taking the X, Y, and Z directions as an example, the monitoring device includes an upper box 420, a gas circulation chamber 421, and a lower box 423. The accommodating cavity is disposed in the gas circulation chamber 421. The upper box 420 and the lower box 423 are connected to form the outer shell of the trainer 41. The gas circulation chamber 421 is housed in the outer shell and is slidably connected to the lower box 423 along the X direction.

[0098] Furthermore, one end of the upper box 420 is provided with a first opening groove 4201, and the lower box 423 is provided with a second opening groove 4233. The first opening groove 4201 and the second opening groove 4233 cooperate to form an opening. The opening cooperates with the air inlet 4211, so that one of the ports of the trainer 41 can be connected to the air inlet 4211 through the opening.

[0099] In some preferred embodiments, the gas flow chamber 421 further includes a load-bearing block 4214, which is connected to the lower end face of the air inlet 4211 and extends toward the outside of the accommodating cavity of the gas flow chamber 421 to support the trainer 41 connected to the air inlet 4211, thereby increasing the stability of the connection between the trainer 41 and the air inlet 4211.

[0100] In some preferred embodiments, the air outlet 4212 and the baffle 4213 are both disposed on the same side of the gas flow chamber 421 along the X direction. Correspondingly, the side of the lower housing 423 is provided with a first elongated slot 4231 and a second elongated slot 4232 extending along the X direction. The air outlet 4212 cooperates with the first elongated slot 4231, and the second elongated slot 4232 cooperates with the baffle 4213. The baffle 4213 is fixedly connected to the outer wall of the gas flow chamber 421 and slidably connected to the second elongated slot 4232. By pushing the position of the baffle 4213 relative to the second elongated slot 4232, the position of the air outlet 4212 relative to the first elongated slot 4231 is changed, thereby adjusting the gas flow area of ​​the air outlet 4212 relative to the outer housing.

[0101] In some preferred embodiments, the air outlet 4212 consists of a plurality of ventilation holes spaced apart along the X direction, so as to quantify the training intensity by the number of ventilation holes exposed through the first elongated slot 4231.

[0102] In some preferred embodiments, a sensor is provided inside the gas flow chamber 421 for detecting the gas flow rate of the trainer 41.

[0103] In some preferred embodiments, the monitoring device further includes a control component 422, which includes a Bluetooth component, a main control chip, and other control modules, for feeding back the airflow information detected by the sensor and feeding it back to the outside.

[0104] Based on the above three embodiments, this application can be used not only as an oral muscle trainer, but also as a lip muscle trainer and a respiratory muscle trainer. When used as a lip muscle trainer, since the wearer's mouth needs to be closed to perform the relevant training, when the wearer's teeth hold the wearing end of the first tube 31, the upper lip is pulled down to contact the lower lip, and the mental muscle contracts to make the lower lip contact the upper lip. Long-term training can enhance the function of the lip muscles, and slightly protruding upper incisors may straighten themselves. When used as a respiratory muscle trainer, during exhalation and inhalation, the wearer needs to exert effort to resist the resistance set by the trainer to increase the strength of the exhalation or inhalation muscles, thereby increasing the strength and endurance of the respiratory muscles and completing the training of the respiratory muscles. The above are just examples of some application scenarios of this application, and the specific application scenarios are not further limited here.

[0105] The specific embodiments of the present invention have been described in detail above. For those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
