Description

Technical Field

[0001] The invention relates to the field of oral equipment, and in particular to an oral expansion device. Background Art

[0002] An existing commonly used expanding device is composed of wings on two sides and a spring part in the middle. The wings on both sides are inserted into the oral cavity by pressing the wings on both sides so that they overcome the spring force and approach each other so that they can be inserted into the oral cavity. After they are inserted into the oral cavity, the wings on both sides open the oral cavity through the restoring force of the spring.

[0003] The disadvantage of this commonly used mouth expander is that the spring force cannot be adjusted, which causes some users to feel uncomfortable after their mouths are stretched open.

[0004] A similar means of solving this problem is a functional oral dilator. The disclosed document provides a solution for controlling the relative distance between two supporting bodies to achieve different degrees of expansion, thereby reducing the pressure and pain of oral expansion and increasing the comfort of use.

[0005] However, the original concept of this method is actually to control the relative distance between the two supporting bodies according to the user's initial physical sensation before use. During use, the discomfort caused by keeping the mouth open for a long time is caused because the relative distance is fixed, so the mouth cannot move and the oral muscles cannot exercise. Therefore, its comfort still needs to be improved. Summary of the invention

[0006] In view of the above, the purpose of the present invention is to provide an oral dilating device with an adjustable elastic structure to address the discomfort problem caused by the use of the oral dilator. The elastic force is adjusted to make the initial physical sensation of use comfortable, and the elastic force is used to enable the oral muscles to maintain a certain amount of activity during use, thereby increasing the comfort of the user.

[0007] An oral expansion device in the present scheme includes two main body parts arranged crosswise, and an axis is provided at the intersection of the two main body parts to connect the two; a side wing part for inserting into the oral cavity is formed in front of the intersection of the two main body parts, and a handle part for hand-holding is formed behind the intersection of the two main body parts, and a spring plate is provided between the two handle parts. When the side wing part is inserted into the oral cavity, the two handle parts overcome the spring force of the spring plate and approach each other, thereby reducing the distance between the front side wing parts for insertion into the oral cavity. After insertion into the oral cavity, the distance between the two side wing parts becomes larger under the action of the spring force to complete the expansion, and the length of the spring plate can be adjusted after insertion to change the magnitude of the spring force.

[0008] Furthermore, the spring plate includes a first leaf spring and a second leaf spring, one end of the first leaf spring and the second leaf spring are respectively connected to the handle parts of the two main parts, and the other ends are overlapped with each other. An adjustment mechanism is provided outside the overlapping part to connect the first leaf spring and the second leaf spring and is transmission connected with the two to drive the overlapping part of the first leaf spring and the second leaf spring to increase or shorten, thereby changing the overall length of the spring plate.

[0009] Furthermore, the adjustment mechanism is connected to a C-shaped buckle of the overlapping part of the first leaf spring and the second leaf spring, and the C-shaped buckle is provided with three surfaces, and three bevel teeth are respectively provided on the three surfaces. The middle one of the three bevel teeth is an adjustment bevel tooth, and the ones on both sides are transmission bevel teeth. The adjustment bevel teeth can drive the two transmission bevel teeth to rotate synchronously in opposite directions. The outer side surfaces of the overlapping part of the first leaf spring and the second leaf spring are respectively provided with teeth that cooperate with the two transmission bevel teeth for transmission. When the two transmission bevel teeth rotate in opposite directions, the overlapping part of the first leaf spring and the second leaf spring can be driven to increase or shorten, thereby changing the overall length of the spring plate.

[0010] Furthermore, the C-shaped clip includes three shaft seats and two C-shaped connecting parts. The C-shaped clip is combined with the three shaft seats through the connecting parts, so that the C-shaped clip has elasticity, so that it can be detachably mounted on the overlapping part of the first leaf spring and the second leaf spring.

[0011] Furthermore, the rear half of the main shaft of the adjusting bevel gear is conical, and an elastic deformation seam is provided in the middle, at least one buckle is designed on the outer periphery, and a hole matching the rear half is provided on the shaft seat corresponding to the adjusting bevel gear, and a circle of card grooves is provided on the inner periphery of the hole.

[0012] Furthermore, the side wing portion is provided with a resonance portion extending outward.

[0013] Compared with existing technologies: 1. The present invention can adapt to different oral cavity sizes; 2. The expansion force can be adjusted according to the size of different oral cavity, so that the user's oral cavity will not be subjected to excessive pressure, which improves the user's comfort; 3. During long-term oral use, it will not hinder the movement of oral muscles, reducing the risk of oral muscle fatigue and damage caused by long-term use; 4. The design of the resonance part can vibrate and massage the oral muscles, helping users relax and relieve themselves. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Reference Figure 1 to Figure 2 The oral cavity expansion device shown in the figure comprises two main body parts arranged crosswise and connected by an axis at the intersection. A side wing part 1 for inserting into the oral cavity is formed in front of each main body part, and a handle part 2 for holding is formed in the rear thereof. A spring plate 3 is arranged between the two handle parts 2. When the oral cavity needs to be expanded, the handle part 2 can be pressed to make the two handle parts 2 overcome the elastic force on the spring plate 3, thereby bringing the two side wings 1 closer together to achieve the purpose of expanding the oral cavity.

[0017] This design can ensure that the expansion device can adapt to different sizes of oral cavity. At the same time, the length of the spring plate 3 can be adjusted after insertion to change the magnitude of the spring force, so that the user's oral cavity will not be subjected to excessive pressure, thereby improving the user's comfort. Moreover, because the oral cavity is opened by the spring force, the movement of the oral muscles will not be hindered during long-term oral use, thereby reducing the risk of oral muscle fatigue and damage caused by long-term use.

[0018] Reference Figure 1As shown, the spring plate 3 includes a first leaf spring 301 and a second leaf spring 302, one end of the first leaf spring 301 and the second leaf spring 302 are respectively connected to the handle parts 2 of the two main body parts, and the other ends are overlapped with each other, and a C-shaped buckle 4 is provided outside the overlapped part to lock the overlapped part, and three bevel teeth are respectively provided on the three surfaces provided with the C-shaped buckle 4, wherein the middle one is an adjustment bevel tooth 5, and the two sides are transmission bevel teeth 6, and the adjustment bevel teeth 5 can drive the two transmission bevel teeth 6 to rotate synchronously in opposite directions, and the outer side surfaces of the overlapped part of the first leaf spring 301 and the second leaf spring 302 are respectively provided with teeth that cooperate with the two transmission bevel teeth 6 for transmission, and when the two transmission bevel teeth 6 rotate in opposite directions, the overlapped part of the first leaf spring 301 and the second leaf spring 302 can be driven to grow or shorten, thereby changing the overall length of the spring plate 3. Such a design is the most concise, which can reduce the production cost of the expansion device and reduce the medical cost of the user, especially since such an inlet device is usually disposable for hygienic needs, so cost control is particularly important.

[0019] Among them, the two main parts mentioned can be made of cheap and disposable materials such as plastic and silicone, which will help to further reduce the manufacturing cost of the product.

[0020] The spring plate 3 needs to withstand a large force during the oral expansion process, so a material with good elasticity and pressure resistance must be selected, such as metal or high-grade engineering plastic.

[0021] As for the C-type buckle 4 and the bevel gear, these parts are not suitable for disposable materials because they need to withstand greater force and wear during use. If plastic is used, the strength of the parts may be insufficient, affecting the service life and safety of the entire product. In this case, metal is undoubtedly a better choice. At the same time, since these parts basically do not contact the oral cavity during the oral expansion process, we consider using metal materials and using the design of the C-type buckle 4 so that it can be easily disassembled and reused. Specifically, in this embodiment, the C-type buckle 4 includes three shaft seats 401 and two C-shaped connecting parts 402, and the three bevel gears are fixed to the three shaft seats 401. The connecting part 402 can make the C-type buckle 4 open and then be stuck in the overlapping part of the first leaf spring 301 and the second leaf spring 302. In this design, the C-type buckle 4 is combined with the three shaft seats 401 through the connecting part 402, so that the C-type buckle 4 has elasticity, thereby realizing the rapid disassembly and assembly with the first leaf spring 301 and the second leaf spring 302; ensuring the flexibility of the adjustment mechanism composed of the C-type buckle 4 and the bevel gear during use.

[0022] In this design, the main function of the adjustment mechanism is to control the overall length of the spring plate 3 composed of the first leaf spring 301 and the second leaf spring 302. Due to the special structure of the spring plate 3, it is composed of two springs, namely the first leaf spring 301 and the second leaf spring 302. Therefore, we need to ensure that the two first leaf springs 301 and the second leaf spring 302 can be tightly combined and will not separate automatically, and we also need to overcome their respective elastic forces to prevent the spring plate 3 from spontaneously lengthening under uncontrolled conditions. This requires an effective control system to achieve this goal. In this design, we use C-type buckle 4 and bevel gear as the main control system. The C-type buckle 4 can clamp the first leaf spring 301 and the second leaf spring 302 through the C-shaped structure, and can also use elastic deformation to achieve rapid disassembly and assembly. The bevel gear drives the first leaf spring 301 and the second leaf spring 302 to move by meshing, and also locks the first leaf spring 301 and the second leaf spring 302 by meshing to prevent the spring plate 3 from spontaneously lengthening under uncontrolled conditions. This requires an effective control to ensure that the bevel gear has a self-locking ability to overcome the spring tension and not rotate in the locked state. This is very important because if the bevel gear rotates in the locked state, it may cause the length of the spring plate 3 to change, thereby affecting the treatment effect. At the same time, it is also required that the bevel gear can be easily rotated in the unlocked state so that the operator can adjust the length of the spring plate 3.

[0023] In this embodiment, the rear half of the main shaft of the adjusting bevel gear 5 is designed to be conical, and an elastic deformation seam 501 is designed in the middle of the tapered rear half, and at least one buckle 502 is designed on the periphery. A hole matching the rear half is provided on the shaft seat 401 corresponding to the adjusting bevel gear 5, and a circle of slots 7 is provided on the inner periphery of the hole. The design of this elastic deformation seam 501 allows the spring plate 3 to have a certain expansion and contraction space when subjected to external forces, and can be retracted inward through the elastic deformation seam 501, so that the buckle 502 is disengaged from the slot 7, so that the adjusting bevel gear 5 can rotate normally. At the same time, after the adjustment is completed, it can be automatically reset to insert the buckle 502 into the buckle 502 to complete the locking, so that the bevel gear is self-locking, thereby effectively locking the spring plate 3. Such a design fully takes into account the convenience of use, especially the convenience of one-handed operation by medical personnel.

[0024] Finally, in another embodiment, the wing portion 1 of the present invention is provided with a resonance portion 8 extending outward. By turning this resonance portion 8, the entire device can be driven to produce a resonance effect, thereby alleviating and eliminating uncomfortable feelings such as oral muscle stiffness that may occur during use. Specifically, when we use the oral expansion device to perform oral expansion operations, it is inevitable that the oral muscles will produce tension, stiffness and other discomforts due to pain or other reasons. At this time, if these muscles can be relaxed in some way, it will undoubtedly greatly improve the comfort level when we use this device. The design of this resonance portion 8 is to allow our muscles to vibrate and massage, helping users to relax and relieve.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
