Description

Technical Field

[0001] This invention relates to a corrective training device, specifically to a tongue muscle training mechanism, a tongue and lip muscle combined training mechanism and system. Background Technology

[0002] The adenoids are lymphatic tissue in the nasopharynx, also known as the pharyngeal tonsils or adenoids. Under normal physiological conditions, they are largest at 6-7 years of age, gradually shrink after 10 years of age, and basically disappear in adulthood. If the adenoids enlarge and cause corresponding symptoms, it is called adenoid hypertrophy. Enlarged adenoids can block the posterior nasal openings, often accompanied by rhinitis and sinusitis, resulting in nasal congestion and runny nose. Symptoms may include mouth breathing, nasal speech, and snoring during sleep. Long-term mouth breathing and nasal congestion can affect facial development, causing facial bone development disorders such as elongated maxilla, high-arched palate, protruding upper incisors, malocclusion, upturned upper lip, thick lips, and lack of facial expression, i.e., "adenoid facies." The incidence of adenoid hypertrophy in children is 9.9%-29.9%, and with the increasing incidence of allergic rhinitis, the proportion of children with adenoid facies caused by mouth breathing due to adenoid hypertrophy resulting from allergic rhinitis will also increase. As parents pay more attention to children's oral health and facial aesthetics, more and more children in the primary dentition and mixed dentition stages are beginning to receive early orthodontic treatment. As an important means of early orthodontic treatment, the market demand for oral and facial muscle function training is growing.

[0003] Currently, some orofacial muscle function training products targeting adenoid facies caused by mouth breathing have attempted to integrate lip muscle training with tongue muscle training. For example, Chinese invention patent application CN121041062A discloses a lip orthodontic correction device, which includes an occlusal pressure plate assembly, a lip muscle pull plate assembly, a training airbag, and connectors. The training airbag can be configured in various forms to achieve training of different parts. In one embodiment of this patent (see Figures 20-21 and corresponding descriptions in its specification), the training airbag is configured as an anterior tongue muscle airbag, including an arc-shaped anterior tongue plate 36 and a tongue plate connecting part 35 connecting the anterior tongue plate 36 to the frame. The tongue plate connecting part 35 has an internal cavity 351, and the rear surface of the anterior tongue plate 36 has several protrusions 37 for massage. When in use, the tongue-pushing airbag presses the tongue-pushing plate 36 forward to train the tongue root muscles. The tongue-pushing plate 36 can swing left and right under the push of the tongue, thereby achieving multi-directional training of the tongue muscles.

[0004] However, in practical use, while the tongue plate can be pushed left and right by the tongue during tongue muscle training, there is a lack of clear feedback mechanism for proper positioning. This means the trainee cannot perceive whether the tongue has pushed the tongue plate to the effective training position. Furthermore, there is a lack of constraints and verification mechanisms for the range of tongue movement. Whether the trainee completes the tongue pushing motion according to the correct range, or whether there is any "laziness" or incomplete movement, cannot be confirmed or guaranteed. The training quality relies entirely on the trainee's subjective awareness, making it difficult to guarantee training effectiveness. In addition, the lack of effective training supervision and guidance, especially for children and adolescents, leads to poor compliance and often fails to achieve the expected myofunctional training results.

[0005] Therefore, how to provide a lip and tongue muscle training mechanism that can effectively guide the tongue to complete reciprocating swing training within a standardized range, ensure that each training movement reaches the effective training position and provides clear feedback is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] This invention aims to provide a tongue muscle training mechanism, a tongue and lip muscle combined training mechanism and system that can effectively guide the tongue to complete reciprocating swing training according to a standardized range, ensure that each training movement reaches the effective training position and has clear feedback on the position.

[0007] The technical solution provided by this invention is as follows: A tongue muscle training mechanism, comprising:

[0008] The bite plate assembly has limit fitting parts at both ends of its rear side;

[0009] The sensing airbag assembly is disposed on the rear side of the bite plate assembly, and includes a first airbag and a second airbag arranged at a distance from left to right, with a clearance gap formed between the first airbag and the second airbag.

[0010] A connecting part is provided on the front side of the bite plate assembly, and an airflow channel is provided inside it. The airflow channel is connected to the first airbag and the second airbag.

[0011] The tongue muscle training board has its middle part pivotally supported on the rear middle of the bite plate assembly, so that the tongue muscle training board can swing back and forth relative to the bite plate assembly.

[0012] Positioning engagement parts are respectively provided at the left and right ends of the front surface of the tongue muscle training board. The positioning engagement parts and the limiting engagement parts on the same side are configured such that when the tongue muscle training board swings to one side to the preset training position, a releaseable positioning engagement is formed between the two to generate tactile and / or auditory feedback signals to indicate that the action is in place, and to limit the tongue muscle training board from continuing to swing to that side.

[0013] The front surface of the tongue muscle training board is also provided with a squeezing part that extends into the clearance gap. The squeezing part is configured to squeeze the first airbag when the tongue muscle training board swings to the left and squeeze the second airbag when it swings to the right, so that the gas in the squeezed airbag is output outward through the airflow channel to form pneumatic feedback.

[0014] In the tongue muscle training mechanism described above, the trainee fixes the mechanism in their mouth by biting down on the occlusal plate assembly with their upper and lower teeth. The trainee pushes the tongue muscle training plate to one side with the tip or body of their tongue, causing the plate to swing around its central pivot point. When the plate reaches the preset training position, the positioning engagement piece on the tongue muscle training plate and the limiting engagement piece on the occlusal plate assembly form a releaseable positioning engagement, generating tactile and / or auditory feedback signals to indicate that the trainee has completed the movement, while simultaneously limiting the plate's continued swing to that side to prevent over-extension. During this process, the compression part on the tongue muscle training plate compresses the corresponding air bladder as it swings, and the gas inside the bladder is released outward through the airflow channel, forming pneumatic feedback and further enhancing the perception of the positioning signal. When the trainee applies a reverse driving force to the other side with their tongue, the positioning engagement is released, and the tongue muscle training plate can continue to swing to the other side, completing a full left-right reciprocating training cycle.

[0015] The tongue muscle training mechanism described above, through a dual mechanism of positioning coordination and pneumatic feedback, ensures that each tongue pushing movement reaches the effective training position and provides the trainee with a clear sense of positioning, effectively solving the problems of the inability to confirm training movements and the dependence of training quality on subjective awareness in existing technologies.

[0016] In a preferred embodiment of the present invention, the releasable positioning engagement includes at least one of a snap-fit ​​engagement and a magnetic engagement. When a snap-fit ​​engagement is used, the limiting engagement portion is a slot, and the positioning engagement member is a snap-fit ​​protrusion; when the tongue muscle training board swings to the preset training position, the snap-fit ​​protrusion engages with the slot to form a snap-fit ​​engagement. Further, the slot has a guide slope and a receiving portion, the receiving portion accommodating the snap-fit ​​protrusion; the slot forms an elastic opening between the guide slope and the receiving portion, the opening size of the elastic opening being smaller than the corresponding size of the snap-fit ​​protrusion, so that the snap-fit ​​protrusion can enter or exit the receiving portion through the elastic opening when subjected to a preset driving force. This structure guides the snap-fit ​​protrusion smoothly into the receiving portion via the guide slope, and achieves reliable positioning retention and releasable separation via the constricted elastic opening, resulting in a simple structure and clear feedback.

[0017] In another preferred embodiment of the invention, the tongue muscle training board is arc-shaped, with its arc-shaped opening facing the tongue; the rear surface of the tongue muscle training board is provided with an anti-slip damping part to increase the contact friction between the tongue and the tongue muscle training board. This arc-shaped design better conforms to the anatomical shape of the tongue, and the anti-slip damping part can prevent the tongue from slipping during the pushing process, improving training efficiency and comfort.

[0018] This invention also provides a combined tongue and lip muscle training mechanism, including the tongue muscle training mechanism described in any of the above claims, and a lip muscle pull plate, which is an arc-shaped plate structure connected to the front side of the occlusal plate assembly via an elastic connector; wherein, the connecting part is located on the side of the lip muscle pull plate away from the occlusal plate assembly, and the airflow channel passes through the connecting part, the lip muscle pull plate, and the elastic connector. This combined training mechanism integrates tongue muscle training and lip muscle training into one unit, allowing the user to simultaneously perform tongue lateral movement training and lip closure training, achieving comprehensive training of the orofacial muscle groups.

[0019] This invention also provides a tongue and lip muscle combined training system, including the aforementioned tongue and lip muscle combined training mechanism, a training host, and a connecting tube. The training host contains a pressure sensor and a control unit. One end of the connecting tube is connected to a connecting end on the connecting part, and the other end is connected to the training host. The pressure sensor communicates with the interior of the first and second airbags through the connecting tube and the airflow channel, and is used to collect the pressure signals inside the first and second airbags in real time. The control unit is electrically connected to the pressure sensor, and is used to receive the electrical signals output by the pressure sensor and convert the electrical signals into training data. This training system converts pneumatic feedback signals into quantifiable electronic data, providing trainees or medical personnel with objective training evaluation criteria, further improving the standardization and compliance of training.

[0020] Compared with the prior art, the tongue muscle training mechanism, tongue and lip muscle combined training mechanism, and training system provided by the present invention have the following beneficial effects:

[0021] (1) Construct a dual-position feedback mechanism to ensure that each training movement reaches the effective position.

[0022] This invention utilizes a releasable positioning engagement between the tongue muscle training board and the occlusal plate assembly. When the tongue muscle training board swings to a preset training position, the positioning engagement and the limiting engagement generate tactile feedback (such as a vibrational feeling of locking in) and / or auditory feedback (such as a "click" sound), allowing the trainee to clearly perceive that the movement has been completed. Simultaneously, the compression part on the tongue muscle training board compresses the corresponding air bladder during the swing, and the gas inside the compressed air bladder is output outward through the airflow channel, forming pneumatic feedback. This pneumatic feedback can generate an auditory signal by connecting to a sound-generating device (such as a whistle), or be converted into visual training data by connecting to a pressure sensor, providing the trainee with objective evidence of movement completion. The synergistic effect of the above-mentioned tactile / auditory feedback and pneumatic feedback effectively overcomes the shortcomings of existing technologies where trainees cannot confirm whether the movement has been completed and the training effect depends on subjective awareness.

[0023] (2) Limit the range of motion to prevent overexertion and ensure training safety.

[0024] The positioning mechanism, while indicating the correct movement, restricts the tongue muscle training board from swinging further to that side, thus precisely limiting the range of motion of the tongue muscle training board within the preset safe training range. This prevents excessive stretching of the tongue and potential injury, making it especially suitable for children and teenagers.

[0025] (3) Guide the tongue to complete the reciprocating motion according to the standard range to improve the quality of training.

[0026] This invention guides trainees to complete training according to a standardized process: "swing to the left → lock in place → apply reverse force to unlock → swing to the right → lock in place." Only when the tongue applies sufficient reverse driving force to release the positioning engagement can the tongue muscle training board swing to the other side. This mechanically forces trainees to complete the full and standardized training movements, preventing "laziness" or incomplete movements and effectively ensuring training quality.

[0027] (4) Integrating lip muscle training function to achieve comprehensive training of oral and facial muscle groups.

[0028] The invention provides a tongue and lip muscle composite training mechanism that integrates a tongue muscle training board and a lip muscle stretching board into the same device. Trainees can simultaneously perform tongue lateral movement training and lip closure training. Multiple muscle function training movements can be completed with one wearing, making it convenient to use and highly efficient.

[0029] (5) The pneumatic signal can be quantified and output to provide objective data support for training and evaluation.

[0030] The airflow channel design provided by this invention can not only generate direct pneumatic feedback signals but also serve as a standardized interface for connecting to external sensors. In the training system, a pressure sensor collects real-time air pressure signals inside the airbag via a connecting tube and the airflow channel. The control unit converts these signals into training data such as the number of training sessions, duration of each compression, and peak air pressure, which is then displayed in real-time on a screen. This transforms the training process from a subjective experience into objective data, facilitating self-monitoring by trainees and remote evaluation of training effectiveness by medical personnel, significantly improving the standardization and scientific rigor of the training.

[0042] Example 1

[0043] This embodiment provides a combined tongue and lip muscle training system, which aims to provide a facial muscle function training device with clear feedback and the ability to guide the tongue to complete reciprocating swing training in a standardized manner for children and adolescents with adenoid facies caused by mouth breathing.

[0044] like Figure 1 As shown, the tongue and lip muscle compound training system provided in this embodiment mainly includes: a tongue and lip muscle compound training mechanism, a training host 60, and a connecting pipe 70. The training host 60 is equipped with a pressure sensor and a control unit, and a display screen 61 electrically connected to the control unit is provided on the front panel of the training host 60. One end of the connecting pipe 70 is connected to the connecting end on the connecting part 21 of the tongue and lip muscle compound training mechanism, and the other end is connected to the training host 60.

[0045] like Figures 2 to 5 As shown, the tongue and lip muscle combined training mechanism mainly includes: a biting plate assembly 10, a lip muscle pull plate 20, a tongue muscle training plate 30, a sensing airbag assembly, and an elastic connector 50.

[0046] In this embodiment, the occlusal plate assembly 10 is the supporting base of the entire training mechanism in the oral cavity. Its surface is covered with medical-grade elastic material. Preferably, the lower surface is provided with occlusal grooves for accommodating the upper and lower dentition. The trainee fixes the training mechanism in the oral cavity by biting the upper and lower dentition into the occlusal grooves. Its preferred structure can also refer to the occlusal pressure plate assembly in CN121041062A.

[0047] In this embodiment, limiting mating portions are symmetrically provided at both ends of the rear side of the bite plate assembly 10. In this embodiment, as... Figure 2 , Figure 5 As shown, the limiting and fitting part is specifically a slot 11 formed at both ends of the rear side of the bite plate assembly 10. Hinge holes 12 are also provided on the upper and lower sides of the middle rear side of the bite plate assembly 10.

[0048] In this embodiment, as Figure 4 , Figure 5 As shown, the sensing airbag assembly is located on the rear side of the bite plate assembly 10, and includes a first airbag 41 and a second airbag 42 arranged at intervals on the left and right. The first airbag 41 and the second airbag 42 are independent airbags, and a clearance gap 43 extending in the front-rear direction is formed between their inner sidewalls.

[0049] In this embodiment, as Figures 2-5 As shown, the connecting part 21 is located on the front side of the occlusal plate assembly 10. Specifically, it is connected to the front side of the occlusal plate assembly 10 via the labial muscle pull plate 20 and the elastic connector 50. Airflow channels 22 are formed inside the connecting part 21, the labial muscle pull plate 20, and the elastic connector 50. The airflow channels 22 communicate with the interiors of the first airbag 41 and the second airbag 42, forming a complete airflow circuit. The front end of the connecting part 21 has a connecting end for connecting external devices.

[0050] In this embodiment, as Figure 6 As shown, the tongue muscle training board 30 is an arc-shaped board with its arc-shaped opening facing the tongue to conform to the natural anatomical curvature of the tongue. The rear surface of the tongue muscle training board 30 is provided with an anti-slip damping part 36 to increase the contact friction between the tongue and the tongue muscle training board 30. In this embodiment, the anti-slip damping part 36 is an elastic damping layer with a textured surface; preferably, it can also be a dot array or a combination of a textured surface and a dot array.

[0051] In this embodiment, a pressing part 35 protrudes forward from the center of the front surface of the tongue muscle training board 30. In this embodiment, the pressing part 35 is plate-shaped, its position corresponding to the clearance gap 43 on the rear side of the biting plate assembly 10, and extends into the clearance gap 43. When the tongue muscle training board 30 is in its initial, non-oscillating state, the pressing part 35 is located in the center of the clearance gap 43, neither contacting the first airbag 41 nor the second airbag 42. Alternatively, the pressing part 35 can also be block-shaped.

[0052] In this embodiment, the tongue muscle training board 30 has integrally formed hinged cantilever arms 33 on both the upper and lower sides of its middle section, and a hinge shaft 34 is provided at the end of the hinged cantilever arms 33. The hinge shaft 34 passes through the hinge hole 12 in the middle of the rear side of the bite plate assembly 10, forming a pivot connection, so that the middle section of the tongue muscle training board 30 can swing back and forth relative to the bite plate assembly 10 around the pivot. It is understood that the pivot connection between the hinge shaft 34 and the hinge hole 12 is only a preferred implementation. In other embodiments, the middle section of the tongue muscle training board 30 can also be supported on the middle of the rear side of the bite plate assembly 10 by means of a ball-and-socket joint, a flexible connector, or other equivalent swingable connection structure.

[0053] In this embodiment, positioning fittings are respectively provided at both ends of the front surface of the tongue muscle training board 30. In this embodiment, as shown... Figure 2 , Figure 6 As shown, the positioning and fitting component is specifically a snap-fit ​​protrusion 32 integrally formed on the tongue muscle training board 30 via a snap-fit ​​cantilever 31. The position of the snap-fit ​​protrusion 32 corresponds to the slot 11 on the bite plate assembly 10, and the snap-fit ​​protrusion 32 and the slot 11 on the same side together form a set of releasable snap-fit ​​positioning and fitting structures.

[0054] Now combined Figure 2 and Figure 6The structural design of the slot 11 is described in detail below. The slot 11 has a guide ramp 111, an elastic opening 112, and a receiving portion 113. The guide ramp 111 is located at the entrance of the slot 11 and is used to guide the engaging protrusion 32 into the slot 11. The receiving portion 113 is located inside the slot 11, and its shape and size match the engaging protrusion 32, used to receive and lock the engaging protrusion 32 after it enters. The elastic opening 112 is formed between the guide ramp 111 and the receiving portion 113, and its opening size is slightly smaller than the corresponding size of the engaging protrusion 32. Since the occlusal plate assembly 10 is made of medical-grade elastic material, the material at the elastic opening 112 can undergo elastic deformation under stress. When the driving force generated by the tongue pushing the locking protrusion 32 reaches or exceeds a preset threshold, the locking protrusion 32 can open the elastic opening 112 and slide into the receiving part 113; when the locking protrusion 32 is in the receiving part 113, the elastic opening 112 returns to its original state, forming a constricted locking, so that the locking protrusion 32 is reliably held in the receiving part 113; when the tongue applies a reverse driving force in the opposite direction to reach the preset threshold, the locking protrusion 32 can open the elastic opening 112 again and disengage from the receiving part 113, thereby realizing a releasable snap-fit ​​engagement.

[0055] In a preferred embodiment, the limiting fitting parts located at the left and right ends of the rear side of the bite plate assembly 10 and the positioning fitting parts located at the left and right ends of the front surface of the tongue muscle training board 30 adopt a magnetic attraction method. Specifically, one of the limiting fitting parts and the positioning fitting parts is a magnetic element, and the other is a magnetic or ferromagnetic element. For example, permanent magnets (or electromagnets) can be embedded at the left and right ends of the rear side of the bite plate assembly 10 as limiting fitting parts, and ferromagnetic metal sheets or permanent magnets with opposite polarities can be embedded at corresponding positions at the left and right ends of the front surface of the tongue muscle training board 30 as positioning fitting parts; or, the above configurations can be interchanged. When the tongue muscle training board 30 swings to the preset training position, the limiting fitting parts and positioning fitting parts on the same side attract each other and adhere under the action of magnetic attraction, forming a releaseable magnetic attraction. This magnetic attraction can produce a "click" sound of adsorption and collision (auditory feedback) and a vibration sensation during adsorption (tactile feedback) at the moment of arrival, clearly indicating to the trainee that the action has been completed. At the same time, the presence of magnetic attraction can limit the tongue muscle training board 30 from swinging to that side, preventing over-extension. When the trainee applies sufficient reverse driving force to the other side with their tongue to overcome the magnetic attraction, the magnetic attraction is released, and the tongue muscle training board 30 can swing to the other side.

[0056] In this embodiment, as Figure 2 , Figure 3As shown, the tongue and lip muscle combined training mechanism of this embodiment also includes a lip muscle tension plate 20. The lip muscle tension plate 20 is an arc-shaped plate structure adapted to the contour of the human lip. The lip muscle tension plate 20 is connected to the front side of the bite plate assembly 10 via an elastic connector 50. Elastic auxiliary stretching ribs 51 are also provided on both sides of the elastic connector 50. The auxiliary stretching ribs 51 work in conjunction with the elastic connector 50 to provide elastic stretching resistance for the trainee to perform lip closure training. The connecting part 21 is located on the side of the lip muscle tension plate 20 away from the bite plate assembly 10, i.e., the front side of the lip muscle tension plate 20. The airflow channel 22 passes through the connecting part 21, the lip muscle tension plate 20, and the elastic connector 50, and communicates with the first airbag 41 and the second airbag 42.

[0057] The following is combined Figure 1 , Figure 2 and Figure 7 This document details the working process of the tongue and lip muscle combined training system provided in this embodiment.

[0058] During training, the trainee places the occlusal plate assembly 10 between the upper and lower teeth and fixes it in place. The lip muscle stretching plate 20 is located between the lips and the teeth, and the tongue muscle training plate 30 is located in front of the tongue. The trainee closes their lips and, by pulling the connecting part outward, the lip muscles overcome the elastic resistance of the elastic connector 50 and the auxiliary stretching ligament 51, thus performing lip muscle function training.

[0059] Simultaneously, the trainee presses the tip or front of their tongue against the rear surface of the tongue muscle training board 30, with the anti-slip damping part 36 providing reliable contact friction to prevent slippage. In the initial state, the tongue muscle training board 30 is in a non-swinging middle position, and the squeezing part 35 is located in the center of the clearance gap 43.

[0060] When the trainee pushes the tongue muscle training board 30 to the left with their tongue, the tongue muscle training board 30 swings to the left around the hinge axis 34. During this process, the locking protrusion 32 on the left gradually approaches the locking groove 11 on the left, and the squeezing part 35 squeezes the first airbag 41 to the left with the swing. The gas in the first airbag 41 is squeezed and then output to the training host 60 through the airflow channel 22 and the connecting pipe 70. When the tongue muscle training board 30 swings to the preset left limit training position, the locking protrusion 32 on the left slides into the elastic opening 112 along the guide slope 111 and finally enters the receiving part 113, and the locking protrusion 32 and the locking groove 11 form a snap-fit ​​engagement. Preferably, at this time, a clear "click" sound (auditory feedback) and / or a snap-fit ​​vibration sensation (tactile feedback) can be generated to clearly indicate to the trainee that the tongue has been pushed to the effective training position. At the same time, the engagement between the locking protrusion 32 and the locking groove 11 restricts the tongue muscle training board 30 from continuing to swing to the left, preventing the tongue from being overstretched.

[0061] Subsequently, the trainee applies a reverse driving force to the right with their tongue. When the reverse driving force reaches a preset threshold, the left-side locking protrusion 32 opens the elastic opening 112 and disengages from the left-side slot 11, and the tongue muscle training board 30 begins to swing to the right. The squeezing part 35 disengages from the first airbag 41, the first airbag 41 regains its elasticity, and the squeezing part 35 gradually approaches and squeezes the second airbag 42, expelling the gas inside the second airbag 42. When the tongue muscle training board 30 swings to the preset right-side extreme training position, the right-side locking protrusion 32 engages in the right-side slot 11, generating a second positioning feedback signal.

[0062] In this way, the trainee completes the standardized left-right back-and-forth tongue swinging training under the dual guidance of the buckle positioning feedback and pneumatic feedback.

[0063] During the tongue training process described above, the air pressure inside the first airbag 41 and the second airbag 42 changes regularly with the squeezing action. The air pressure sensor collects the air pressure signals inside the first airbag 41 and the second airbag 42 in real time through the connecting pipe 70 and the airflow channel 22, and converts them into electrical signals which are transmitted to the control unit. After receiving the electrical signals, the control unit processes them and converts them into training data, including the number of training sessions, the duration of each squeeze, and the peak air pressure, which is displayed in real time on the display screen 61. Trainees or medical personnel can observe the changes in the data on the display screen 61 to intuitively understand the standardization, frequency, and intensity of the training, thereby objectively evaluating the training effect and providing targeted guidance.

[0064] In summary, the tongue and lip muscle composite training system provided in this embodiment constructs a clear positioning perception and training guidance system through a dual mechanism of snap-fit ​​and pneumatic feedback, effectively solving the technical problems in existing technologies where tongue muscle training movements cannot be confirmed to be in place and training quality depends on subjective awareness. The curved tongue muscle training board, combined with the design of the anti-slip damping part, improves training comfort and efficiency. The integrated lip muscle training function realizes comprehensive training of the orofacial muscle groups. Quantifiable air pressure data output and real-time display provide objective scientific basis for training evaluation.

[0065] Example 2

[0066] This embodiment provides a tongue muscle training mechanism, which differs from the tongue and lip muscle combined training mechanism in Embodiment 1 in that it does not include a lip muscle pull board and is only used for tongue muscle training.

[0067] In summary, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
