Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical supplies, in particular to a multifunctional dental appliance. BACKGROUND

[0002] Malocclusion is a common oral disease, which can affect the appearance, growth and development, mastication and language function of the maxillofacial region. Therefore, it is necessary to treat malocclusion that may occur or has occurred. However, under normal circumstances, the number of cariogenic bacteria increases significantly after placing a fixed appliance in the oral cavity, which significantly increases the number of caries, missing and filled teeth (dental caries becomes more severe), and tongue side plaque accumulation also increases.

[0003] To solve the above problems, the current solution is to apply a fluoride film formed by fluoride on the inner side of the dental appliance during the manufacture of the dental appliance, or to directly dissolve fluoride solute in the silicone material of the dental appliance, so that fluoride ions are released from the fluoride film or the silicone material through saliva when the user wears the appliance. However, since the fluoride film or the silicone material formed by fluoride directly contacts saliva in the oral cavity, the release period of fluoride is short, and the release amount and release rate are uncontrollable, so that better treatment effect cannot be achieved.

DETAILED DESCRIPTION

[0048] In order to better understand the purpose, technical scheme and advantages of the embodiments of the present application, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, and not all the embodiments.

[0049] It needs to be further explained that the terms in the specification, claims and above-mentioned drawings of the present application, such as one element being located on another element, being connected to another element, the element can be directly located on another element, connected to another element or there can be intermediate elements. In contrast, when one element is called “directly” located on another element, “directly connected” to another element, there will be no intermediate element.

[0050] In the embodiments of the present application, the terms “first”, “second”, “third” and the like are used to distinguish similar objects and are not used to describe a specific order or sequence. The data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms “contain”, “include”, “have” and the like indicate the presence of the claimed features, but do not exclude one or more other features. Spatial relationship terms such as “upper”, “lower”, “left”, “right”, “front”, “back” and the like indicate the spatial positional relationship between one feature and another feature in the drawings, and it should be understood that the spatial relationship terms include different orientations of the device during use or operation, in addition to the orientation indicated in the drawings. For example, when the device in the drawing is inverted, the feature originally described as “below” the feature can be described as “above” the feature.

[0051] Malocclusion is a common oral disease, which can affect the appearance of the maxillofacial region, growth and development, mastication and language function. Therefore, it is necessary to correct the malocclusion that may occur and has occurred. However, in general, the number of cariogenic bacteria increases significantly after the fixed appliance is placed in the oral cavity, which makes the number of caries, missing and supplemented teeth of the patient increase significantly (the caries becomes more serious), and the tongue side plaque accumulation also increases.

[0052] To solve the above problems, the current solution is to apply a fluoride film formed by fluoride on the inner side of the dental appliance when the dental appliance is made, or to directly dissolve fluoride solute in the silicone material of the dental appliance, so that the fluoride ions are released from the fluoride film or the silicone material through saliva when the user wears the appliance. However, since the fluoride film or the silicone material formed by fluoride directly contacts with saliva in the oral cavity, the release period of fluoride is short, and the release amount and release rate are uncontrollable, so that better treatment effect cannot be achieved.

[0053] The embodiment of the present application provides a multifunctional dental appliance to solve the problem of uncontrollable fluoride speed in the prior art, and further solve the problem that the appliance cannot prevent caries and other diseases.

[0056] Referring to Figures 1 to 8As shown, the embodiment of the present application provides a multifunctional dental appliance 100, comprising: an appliance main body 1, a containing cavity (not shown), a functional part 2. Wherein the appliance main body 1 comprises an upper main body 11 for wearing upper jaw teeth and a lower main body 12 for wearing lower jaw teeth, and the containing cavity is arranged in the appliance main body 1. The functional part 2 is arranged in the containing cavity in a detachable manner. When the functional part 2 is placed in the containing cavity, one end surface of the functional part 2 can close the containing opening of the containing cavity, and in the closed state, the one end surface of the functional part 2 constitutes part of the end surface of the appliance main body 1. The functional part 2 is configured to contain and release reagents, and by adjusting the functional part 2, the release rate of the reagents is controlled, and reagents with different release rates are delivered to the oral cavity. The specific structure and connection relationship of each component will be described in detail below.

[0057] Specifically, in the embodiment, the containing cavity can be arranged in the upper main body 11, or in the lower main body 12, or between the upper main body 11 and the lower main body 12. The shape and size of the containing cavity can be set according to the structure and size of the functional part 2. The containing cavity has a containing opening, which can be located on the surface of any part of the appliance main body 1. For example, the containing opening can be located on the surface of the upper main body 11, or the containing opening can be located on the surface of the lower main body 12, or the containing opening can be located on the surface of the lingual stop.

[0058] The functional part 2 is arranged in the containing cavity in a detachable manner, which facilitates the replacement and installation of the functional part 2. When the functional part 2 is placed in the containing cavity, one end surface of the functional part 2 can close the containing opening of the containing cavity, and in the closed state, the one end surface of the functional part 2 constitutes part of the end surface of the appliance main body 1, which can make the end surface of the appliance main body 1 complete to meet the shape required by the appliance main body 1 for correcting teeth. Moreover, the material of the one end surface of the functional part 2 and the end surface of the appliance main body 1 is the same, which further meets the requirements of the appliance main body 1 for correcting teeth. The functional part 2 can contain and release reagents, and by adjusting the functional part 2, the release rate of the reagents is controlled, and reagents with different release rates are delivered to the oral cavity through the delivery structure 6.

[0059] Specifically, in the present embodiment, the functional part 2 comprises a reagent accommodating cavity 3, a releasing part 4 and an adjusting part 5. The reagent accommodating cavity 3 is used to accommodate reagents, and the shape of the reagent accommodating cavity 3 can be set according to requirements, such as a cylinder, a cube, etc. The reagents include fluoride, mouthwash, other reagents for cleaning teeth, and other fruit-flavored reagents. The releasing part 4 is connected with the reagent accommodating cavity 3, and is used to obtain and release the reagents in the reagent accommodating cavity 3. The outer wall of the releasing part 4 and the inner wall of the reagent accommodating cavity 3 form a releasing gap, which is used to release the reagents from the releasing part 4, so that the reagents are further conveyed by the conveying structure 6. Of course, in an example, a region of the outer wall of the releasing part 4 can directly serve as a part of the end face of the appliance main body 1, that is, a part of the end face of the appliance main body 1 is hollowed out, and a region of the outer wall of the releasing part 4 is filled in the hollowed-out part.

[0060] In the present embodiment, the connection mode of the releasing part 4 and the reagent accommodating cavity 3 can be integral connection or detachable connection. The present embodiment preferably adopts the detachable connection mode of the releasing part 4 and the reagent accommodating cavity 3. In this way, after the reagents in the reagent accommodating cavity 3 are released, the reagent accommodating cavity 3 can be detached from the releasing part 4, and the required reagents can be supplemented to the reagent accommodating cavity 3 in time through the opening of the reagent accommodating cavity 3. Or a new reagent accommodating cavity 3 storing reagents can be directly replaced.

[0061] Further, the structure adopted by the detachable connection mode comprises a threaded structure provided at the screwing connection position of the releasing part 4 and the reagent accommodating cavity 3. Specifically, the threaded structure comprises an inner thread provided at the opening of the reagent accommodating cavity 3 and an outer thread provided on the releasing part 4. The releasing part 4 and the reagent accommodating cavity 3 are connected and detached through the screwing mode of the inner thread and the outer thread. Of course, in order to maintain the sealing performance of the screwing connection position of the releasing part 4 and the reagent accommodating cavity 3 during screwing, the screwing connection position of the releasing part 4 and the reagent accommodating cavity 3 is wrapped with a sealing sleeve, which can prevent the reagents from leaking out of the screwing connection position of the releasing part 4 and the reagent accommodating cavity 3. In an example, the structure adopted by the detachable connection mode comprises a clamping structure provided at the screwing connection position of the releasing part 4 and the reagent accommodating cavity 3. Specifically, the clamping structure comprises a clamping groove provided at the opening of the reagent accommodating cavity 3 and a protrusion provided on the releasing part 4. The releasing part 4 and the reagent accommodating cavity 3 are connected and detached through the clamping mode of the clamping groove and the protrusion. The adjusting part 5 is connected with the releasing part 4, and is used to adjust the releasing part 4, so that the releasing part 4 releases the reagents at different releasing rates.

[0062] Further, in the embodiment, the releasing component 4 comprises a releasing cavity 41 in the shape of a cylinder, the partial accommodating cavity has a shape matching the releasing cavity 41, and a region of the inner wall of the partial accommodating cavity is provided with a groove structure. The outer wall of the releasing cavity 41 is in contact with the inner wall of the partial accommodating cavity and rotates relative to the inner wall of the partial accommodating cavity. The releasing cavity 41 is connected to the reagent accommodating cavity 3 through a buckle assembly, and the releasing cavity 41 rotates synchronously with the reagent accommodating cavity 3, and the reagent accommodating cavity 3 rotates relative to the inner wall of the partial accommodating cavity. The buckle assembly comprises a clamping groove and a buckle, and the buckle assembly is arranged to not only realize the connection between the releasing cavity 41 and the reagent accommodating cavity 3, but also facilitate the disassembly and separation of the releasing cavity 41 and the reagent accommodating cavity 3.

[0063] In the embodiment, in order to enable the releasing cavity 41 to release reagents at different release rates, the releasing cavity 41 has releasing cavity wall regions 42 of different release rates, and the releasing cavity wall regions 42 of different release rates are sequentially arranged along the circumferential cavity of the releasing cavity 41 in the shape of a cylinder, and are used to release reagents at different release rates. When a releasing cavity wall region 42 rotates to the inner wall of the partial accommodating cavity with a groove structure, the groove structure and the outer wall of the releasing cavity wall region 42 form a release gap, and the releasing cavity wall region 42 releases reagents at the release rate of the releasing cavity wall region 42 through the release gap. The remaining releasing cavity wall regions 42 are correspondingly rotated to the remaining inner wall of the partial accommodating cavity, the outer wall of the remaining releasing cavity wall regions 42 is correspondingly in contact with the remaining inner wall of the partial accommodating cavity, and the outer wall of the releasing cavity wall region 42 is closed by the remaining inner wall of the partial accommodating cavity. That is, when reagents at a corresponding release rate need to be released, only the releasing cavity wall region 42 of the corresponding release rate of the releasing cavity 41 is rotated to the position of the inner wall of the partial accommodating cavity with a groove structure, so that the releasing cavity wall region 42 at the release rate releases reagents under the release gap, and at the same time, the remaining releasing cavity wall regions 42 of the remaining releasing cavities 41 are closed by the remaining inner wall of the partial accommodating cavity, and the remaining releasing cavity wall regions 42 of the remaining releasing cavities 41 do not release reagents.

[0064] In the present embodiment, the release cavity wall region 42 of different release rates is provided with a plurality of through holes 43 of corresponding aperture sizes, the aperture sizes of the through holes 43 on each release cavity wall region 42 are different, and the through holes 43 of different aperture sizes make the release rates of each release cavity wall region 42 different. For example, the release cavity wall regions 42 of different release rates of the release cavity 41 are three, i.e. the A release cavity wall region 42, the B release cavity wall region 42 and the C release cavity wall region 42, the corresponding release rate of the A release cavity wall region 42 is 0.5 ml / s (ml represents the unit volume), the corresponding release rate of the B release cavity wall region 42 is 0.1 ml / s, and the corresponding release rate of the C release cavity wall region 42 is 1 ml / s. Assuming that the number of the through holes 43 on the A release cavity wall region 42, the B release cavity wall region 42 and the C release cavity wall region 42 is equal (for example, 10 through holes 43), then the aperture of the through holes 43 on the A release cavity wall region 42 is 0.5 mm, the aperture of the through holes 43 on the B release cavity wall region 42 is 0.1 mm, and the aperture of the through holes 43 on the C release cavity wall region 42 is 1 mm. Of course, in other examples, the number of the through holes 43 on the A release cavity wall region 42, the B release cavity wall region 42 and the C release cavity wall region 42 can be unequal, and the apertures of the through holes 43 on one release cavity wall region 42 can also be unequal, as long as the preset release rate can be achieved.

[0065] In order to accurately adjust the rotation of the release cavity 41, the adjusting component 5 includes an adjusting shaft 51, and the circumferential end face of the adjusting shaft 51 is provided with different adjusting mark regions 52, each adjusting mark region 52 is opposite to each release cavity wall region 42. For example, the mark of the A adjusting mark region 52 is 0.5, the mark of the B adjusting mark region 52 is 0.1, the mark of the C adjusting mark region 52 is 1, and the like. The adjusting shaft 51 is fixedly connected with the release cavity 41, and the adjusting shaft 51 drives the release cavity 41 to rotate relative to the reagent containing cavity 3. It needs to be supplemented that the outer end face of the adjusting shaft 51 constitutes part of the end face of the appliance main body 1.

[0066] In the present embodiment, based on the outer end face of the adjusting shaft 51 constituting part of the end face of the appliance main body 1, in order to facilitate taking out the end face of the appliance main body 1 from the adjusting shaft 51, thereby taking out the release cavity 41 and the reagent containing cavity 3. Then the adjusting shaft 51 further includes a handle (not shown), and the outer end face of the adjusting shaft 51 is provided with a groove (not shown) matched with the handle, and the handle is arranged in the groove in a hinged manner. When the adjusting shaft 51 needs to be taken out, the handle can be first flipped out of the groove, so as to drive the adjusting shaft 51, the release cavity 41 and the reagent containing cavity 3 to be taken out from the containing cavity through the handle.

[0067] In the embodiment, the releasing component 4 can also have the following structure: specifically, the releasing component 4 includes a releasing cavity 41 in the shape of a cylinder, the partial accommodating cavity has a shape matching the releasing cavity 41, and a region of the inner wall of the partial accommodating cavity is provided with a groove structure. The outer wall of the releasing cavity 41 is attached to the inner wall of the partial accommodating cavity and rotates relative to the inner wall of the accommodating cavity. The releasing cavity 41 is rotationally connected to the reagent accommodating cavity 3 to realize the rotation of the releasing cavity 41 relative to the inner wall of the accommodating cavity. The releasing cavity 41 is rotationally connected to the reagent accommodating cavity 3, which can be realized by a rotating structure 7 arranged between the releasing cavity 41 and the reagent accommodating cavity 3. In one example, the rotating structure 7 includes a connecting disc 73 and a rotating shaft 74. In this example, the connecting disc 73 is circular and has the same size as the reagent accommodating cavity 3. The circumferential end face of the connecting disc 73 is detachably connected to the inner wall of the reagent accommodating cavity 3. One end of the rotating shaft 74 is rotationally connected to the connecting disc 73, and the other end is connected to the releasing cavity 41, so that the releasing cavity 41 rotates synchronously with the connecting disc 73. The connecting disc 73 is provided with a first through hole 75, so that the reagent in the reagent accommodating cavity 3 is released from the first through hole 75 to the releasing cavity 41. The radial end face of the rotating shaft 74 is provided with a second through hole, so that the reagent in the reagent accommodating cavity 3 is released from the second through hole to the releasing cavity 41.

[0068] In another example, the rotating structure 7 includes a rotating bearing 71 and a limiting assembly 72. One end of the rotating bearing 71 is arranged at the opening of the reagent accommodating cavity 3, and the other end of the rotating bearing 71 is connected to the interface of the releasing cavity 41 (the interface protrudes from the releasing cavity 41) to enable the releasing cavity 41 to rotate relative to the reagent accommodating cavity 3 while realizing the connection between the releasing cavity 41 and the reagent accommodating cavity 3, so that the releasing cavity 41 can release the reagent of the reagent accommodating cavity 3.

[0069] The limiting assembly 72 is detachably connected between the interface of the releasing cavity 41 and the rotating bearing 71. The limiting assembly 72 is used to limit the connection between the interface of the releasing cavity 41 and the rotating bearing 71, that is, when it is necessary to connect the interface of the releasing cavity 41 to the other end of the rotating bearing 71, the interface of the releasing cavity 41 is connected to the other end of the rotating bearing 71 through the limiting assembly 72, and when it is not necessary to connect the interface of the releasing cavity 41 to the other end of the rotating bearing 71, the interface of the releasing cavity 41 is disassembled from the other end of the rotating bearing 71 through the limiting assembly 72. The limiting assembly 72 includes a limiting groove and a limiting protrusion. The limiting groove is arranged on the end face of the other end of the rotating bearing 71, and the limiting protrusion is arranged at the position of the interface of the releasing cavity 41 and opposite to the limiting groove. The connection between the interface of the releasing cavity 41 and the other end of the rotating bearing 71 is realized through the clamping of the limiting groove and the limiting protrusion. The limiting assembly 72 is arranged without affecting the rotational connection between the releasing cavity 41 and the reagent accommodating cavity 3, and can also realize the connection and disassembly of the releasing cavity 41 and the reagent accommodating cavity 3, so as to ensure that the reagent accommodating cavity 3 can be timely supplemented with reagent after the corresponding reagent is consumed.

[0070] It should be noted that when the limiting assembly 72 is used to connect the release cavity 41 and the reagent accommodating cavity 3, the threaded structure or the clamping structure can be removed to simplify the complexity of the connection structure of the release cavity 41 and the reagent accommodating cavity 3.

[0071] In the embodiment, in order to make the release cavity 41 release reagents at different release rates, the release cavity 41 has release cavity wall regions 42 of different release rates, which are sequentially arranged along the circumferential cavity of the columnar release cavity 41, and are used to release reagents at different release rates. When a release cavity wall region 42 is rotated to the inner wall of the partial accommodating cavity with a groove structure, the groove structure and the outer wall of the release cavity wall region 42 form a release gap, and the release cavity wall region 42 releases reagents at the release rate of the release cavity wall region 42 through the release gap. The remaining release cavity wall regions 42 are correspondingly rotated to the remaining inner walls of the partial accommodating cavity, the outer walls of the remaining release cavity wall regions 42 are correspondingly attached to the remaining inner walls of the partial accommodating cavity, and the outer walls of the release cavity wall regions 42 are closed by the remaining inner walls of the partial accommodating cavity. That is, when reagents of a corresponding release rate need to be released, only the release cavity wall region 42 of the corresponding release rate of the release cavity 41 is rotated to the position of the inner wall of the partial accommodating cavity with a groove structure, so that the release cavity wall region 42 of the release rate releases reagents under the release gap, and at the same time, the release cavity wall regions 42 of the remaining release cavities 41 are closed by the remaining inner walls of the accommodating cavity, and the release cavity wall regions 42 of the remaining release cavities 41 will not release reagents.

[0072] In the present embodiment, the release cavity wall region 42 of different release rates is provided with a plurality of through holes 43 of corresponding aperture sizes, the aperture sizes of the through holes 43 on each release cavity wall region 42 are different, and the through holes 43 of different aperture sizes make the release rates of each release cavity wall region 42 different. For example, the release cavity wall regions 42 of different release rates of the release cavity 41 are three, i.e. the A release cavity wall region 42, the B release cavity wall region 42 and the C release cavity wall region 42, the corresponding release rate of the A release cavity wall region 42 is 0.5 ml / s (ml represents the unit volume), the corresponding release rate of the B release cavity wall region 42 is 0.1 ml / s, and the corresponding release rate of the C release cavity wall region 42 is 1 ml / s. Assuming that the number of the through holes 43 on the A release cavity wall region 42, the B release cavity wall region 42 and the C release cavity wall region 42 is equal (for example, 10 through holes 43), then the aperture of the through holes 43 on the A release cavity wall region 42 is 0.5 mm, the aperture of the through holes 43 on the B release cavity wall region 42 is 0.1 mm, and the aperture of the through holes 43 on the C release cavity wall region 42 is 1 mm. Of course, in other examples, the number of the through holes 43 on the A release cavity wall region 42, the B release cavity wall region 42 and the C release cavity wall region 42 can be unequal, and the apertures of the through holes 43 on one release cavity wall region 42 can also be unequal, as long as the preset release rate can be achieved.

[0073] In order to accurately adjust the rotation of the release cavity 41, the adjusting component 5 includes an adjusting shaft 51, and the circumferential end face of the adjusting shaft 51 is provided with different adjusting mark regions 52, each adjusting mark region 52 is opposite to each release cavity wall region 42. For example, the mark of the A adjusting mark region 52 is 0.5, the mark of the B adjusting mark region 52 is 0.1, the mark of the C adjusting mark region 52 is 1, and the like. The adjusting shaft 51 is fixedly connected with the release cavity 41, and the adjusting shaft 51 drives the release cavity 41 to rotate relative to the reagent containing cavity 3. It needs to be supplemented that the outer end face of the adjusting shaft 51 constitutes part of the end face of the appliance main body 1.

[0074] In the present embodiment, based on the outer end face of the adjusting shaft 51 constituting part of the end face of the appliance main body 1, in order to facilitate taking out the end face of the appliance main body 1 from the adjusting shaft 51, thereby taking out the release cavity 41 and the reagent containing cavity 3. Then the adjusting shaft 51 further includes a handle (not shown), and the outer end face of the adjusting shaft 51 is provided with a groove (not shown) matched with the handle, and the handle is arranged in the groove in a hinged manner. When the adjusting shaft 51 needs to be taken out, the handle can be first flipped out of the groove, so as to drive the adjusting shaft 51, the release cavity 41 and the reagent containing cavity 3 to be taken out from the containing cavity through the handle.

[0075] In the embodiment, the releasing component 4 can also have the following structure: specifically, the releasing component 4 includes a first releasing cavity 44 and a second releasing cavity 45 in the form of a cylinder, the partial accommodating cavity has a form matched with the first releasing cavity 44, and there is a releasing gap between the outer wall of the first releasing cavity 44 and the inner wall of the partial accommodating cavity, and the outer wall of the first releasing cavity 44 is fixed relative to the inner wall of the accommodating cavity. The first releasing cavity 44 is fixedly connected with the reagent accommodating cavity 3. The second releasing cavity 45 is rotatably connected with the reagent accommodating cavity 3, and the second releasing cavity 45 is sleeved in the first releasing cavity 44, the outer wall of the second releasing cavity 45 is arranged in close contact with the inner wall of the first releasing cavity 44, and the second releasing cavity 45 rotates relative to the first releasing cavity 44. Among them, the second releasing cavity 45 is rotatably connected with the reagent accommodating cavity 3, which can be realized through the rotating structure 7 arranged between the second releasing cavity 45 and the reagent accommodating cavity 3, and the rotating structure 7 includes a rotating bearing 71 and a limiting assembly 72, one end of the rotating bearing 71 is arranged at the opening of the reagent accommodating cavity 3, and the other end of the rotating bearing 71 is connected with the interface of the second releasing cavity 45 (the interface protrudes from the releasing cavity 41), so that the second releasing cavity 45 can rotate relative to the reagent accommodating cavity 3, and at the same time, the connection between the second releasing cavity 45 and the reagent accommodating cavity 3 can be realized, so that the second releasing cavity 45 can release the reagent in the reagent accommodating cavity 3.

[0076] The limiting assembly 72 is detachably connected between the interface of the second releasing cavity 45 and the rotating bearing 71, and is used for limiting the connection between the interface of the second releasing cavity 45 and the rotating bearing 71, that is, when it is needed to connect the interface of the second releasing cavity 45 with the other end of the rotating bearing 71, the interface of the second releasing cavity 45 is connected with the other end of the rotating bearing 71 through the limiting assembly 72, and when it is not needed to connect the interface of the second releasing cavity 45 with the other end of the rotating bearing 71, the interface of the second releasing cavity 45 is separated from the other end of the rotating bearing 71 through the limiting assembly 72. The limiting assembly 72 includes a limiting groove and a limiting protrusion, wherein the limiting groove is arranged on the end face of the other end of the rotating bearing 71, and the limiting protrusion is arranged at the position of the interface of the second releasing cavity 45 and opposite to the limiting groove, and the connection between the interface of the second releasing cavity 45 and the other end of the rotating bearing 71 is realized through the clamping of the limiting groove and the limiting protrusion. The limiting assembly 72 is arranged without affecting the rotatable connection between the second releasing cavity 45 and the reagent accommodating cavity 3, and also can realize the connection and separation between the second releasing cavity 45 and the reagent accommodating cavity 3, so as to ensure that the reagent in the reagent accommodating cavity 3 can be supplemented in time after the corresponding reagent is consumed.

[0077] In the embodiment, in order to make the first releasing cavity 44 release reagents at different release rates, the first releasing cavity 44 has a first releasing cavity wall area 46 with different release rates, and the first releasing cavity wall areas 46 with different release rates are arranged in sequence along the circumferential cavity of the cylindrical first releasing cavity 44, and the first releasing cavity wall areas 46 with different release rates are used for releasing reagents at different release rates.

[0078] In the present embodiment, the plurality of through holes 43 of different aperture sizes are arranged on the first release cavity wall region 46 of different release rates, and the aperture sizes of the through holes 43 on each first release cavity wall region 46 are different, and the through holes 43 of different aperture sizes make the release rates of each first release cavity wall region 46 different. For example, the first release cavity wall regions 46 of different release rates of the first release cavity 44 are set to three, i.e. the A first release cavity wall region 46, the B first release cavity wall region 46 and the C first release cavity wall region 46, the corresponding release rate of the A first release cavity wall region 46 is 0.5 ml / s (ml represents the unit volume), the corresponding release rate of the B first release cavity wall region 46 is 0.1 ml / s, and the corresponding release rate of the C first release cavity wall region 46 is 1 ml / s. If the number of the through holes 43 on the A first release cavity wall region 46, the B first release cavity wall region 46 and the C first release cavity wall region 46 is equal (for example, 10 through holes 43), then the aperture of the through holes 43 on the A first release cavity wall region 46 is 0.5 mm, the aperture of the through holes 43 on the B first release cavity wall region 46 is 0.1 mm, and the aperture of the through holes 43 on the C first release cavity wall region 46 is 1 mm. Of course, in other examples, the number of the through holes 43 on the A first release cavity wall region 46, the B first release cavity wall region 46 and the C first release cavity wall region 46 can be unequal, and the apertures of the through holes 43 on one first release cavity wall region 46 can also be unequal, as long as the preset release rate can be achieved.

[0079] After the first release cavity wall regions 46 of different release rates of the first release cavity 44 are set, the reagent can be released to the corresponding first release cavity wall region 46 with the release rate. Specifically, the second release cavity 45 can be used to achieve this, i.e. the second release cavity 45 has a second release cavity wall region 47, which can be docked with any first release cavity wall region 46 of the first release cavity 44 when the second release cavity 45 rotates, and after docking, the reagent contained in the second release cavity 45 is released through the second release cavity wall region 47 and the first release cavity wall region 46 docked with the second release cavity wall region 47. That is, when the reagent of the corresponding rate needs to be released, only the second release cavity wall region 47 of the second release cavity 45 needs to be aligned with the first release cavity wall region 46 of the first release cavity 44 corresponding to the release rate.

[0080] The shape and size of the above-mentioned accommodation cavity can be set according to the structure and size of the release member 4.

[0081] In order to accurately rotate the release cavity, the adjusting component 5 comprises an adjusting shaft 51, and the circumferential end face of the adjusting shaft 51 is provided with different adjusting mark areas 52, each adjusting mark area 52 is opposite to each release cavity wall area. For example, the mark of the A adjusting mark area 52 is 0.5, the mark of the B adjusting mark area 52 is 0.1, the mark of the C adjusting mark area 52 is 1, and the like. The adjusting shaft 51 is fixedly connected with the first release cavity 44 and the second release cavity 45, and the adjusting shaft 51 drives the second release cavity 45 to rotate relative to the reagent containing cavity 3.

[0082] In the embodiment, the outer end face of the adjusting shaft 51 constitutes part of the end face of the appliance main body 1, and the end face of the appliance main body 1 is convenient to take out the adjusting shaft 51, so as to take out the release cavity 41 and the reagent containing cavity 3. Therefore, the adjusting shaft 51 further comprises a handle (not shown), and the outer end face of the adjusting shaft 51 is provided with a groove (not shown) matched with the handle. When the adjusting shaft 51 needs to be taken out, the handle can be first turned out of the groove, so as to drive the adjusting shaft 51, the release cavity 41 and the reagent containing cavity 3 to be taken out of the containing cavity through the handle.

[0083] It needs to be further explained that the outer end face of the adjusting shaft 51 constitutes part of the end face of the appliance main body 1.

[0084] After the reagent is released through the release component 4, the reagent needs to be delivered to the oral cavity. Specifically, the delivery structure 6 is arranged in the appliance main body 1, one end of the delivery structure 6 is communicated with the release gap, and the other end is communicated with the end face of the appliance main body 1. The release rate of the reagent is controlled through the adjusting function 2, and the reagent with different release rates is delivered to the oral cavity through the delivery structure 6.

[0085] The delivery structure 6 comprises a delivery pipeline 61, and the delivery pipeline 61 is arranged in the wall body of the upper main body 11 and the lower main body 12 respectively. The first end of the delivery pipeline 61 is communicated with the release gap, and the second end of the delivery pipeline 61 is communicated with the end face of the upper main body 11 and the lower main body 12 respectively. The pipeline diameter of the delivery pipeline 61 gradually decreases from the first end to the second end, and the delivery pipeline 61 is arranged in a gradually decreasing form. The gradually decreasing form not only increases the pressure of the reagent released from the second end of the delivery pipeline 61, but also prevents foreign matters such as the oral cavity from entering the release component 4 through the second end of the delivery pipeline 61 in the reverse direction. The second end of the delivery pipeline 61 is provided with an output port 62, and the diameter of the output port 62 is greater than the diameter of the delivery pipeline 61, so as to facilitate the rapid release of the reagent to the oral cavity.

[0086] In an embodiment, if the releasing component 4 comprises a releasing cavity in the shape of a cylinder, the first end of the delivery conduit 61 communicates with a releasing cavity wall region of the releasing cavity. If the releasing component 4 comprises a first releasing cavity 44 and a second releasing cavity 45 in the shape of a cylinder, the first end of the delivery conduit 61 communicates with a first releasing cavity wall region 46 of the first releasing cavity 44.

[0087] In an example, the delivery conduit 61 comprises a main delivery conduit 611 and a plurality of branch delivery conduits 612, the main delivery conduit 611 is distributed in the wall of the upper body 11 and the lower body 12 in the horizontal direction, the plurality of branch delivery conduits 612 are distributed in the wall of the upper body 11, the lower body 12 and the tongue stop portion in the vertical direction, and one end of each branch delivery conduit 612 communicates with the main delivery conduit 611, and the other end communicates with the tooth abutting end surface of the upper body 11, the lower body 12 and the tongue stop portion. In this embodiment, the other end of each branch delivery conduit 612 can be provided corresponding to each tooth end surface, so that the reagent can be directly transmitted to each corresponding tooth. In this embodiment, the pipe diameters of the main delivery conduit 611 and the branch delivery conduit 612 are the same or different, and the embodiment preferably adopts the setting mode that the pipe diameters of the main delivery conduit 611 and the branch delivery conduit 612 are different, and specifically, the pipe diameter of the main delivery conduit 611 is greater than that of the branch delivery conduit 612, for example, the pipe diameter of the main delivery conduit 611 is set to 1 mm, and the pipe diameter of the branch delivery conduit 612 is set to 0.3 mm. This pipe diameter setting mode is not only conducive to the timely and rapid transmission of the reagent through the main delivery conduit 611, but also conducive to slowing down the delivery of the reagent to the tooth end surface through the branch delivery conduit 612 with a smaller pipe diameter when the reagent reaches the branch delivery conduit 612. The branch delivery conduit 612 is provided with an output port 62, which is located at the tooth abutting end surface of the upper body 11, the lower body 12 and the tongue stop portion, and the diameter of the output port 62 is greater than the diameter of the branch delivery conduit 612, so as to facilitate the rapid release of the reagent in the oral cavity.
