Description

Technical Field

[0001] This utility model relates to the field of teeth whitening tray technology, specifically to a teeth whitening tray. Background Technology

[0002] As modern people place increasing importance on dental aesthetics, more and more teeth whitening products are appearing on the market. Whitening trays are one such product, which can decompose pigment molecules on the tooth surface by generating free radicals from the whitening agent placed inside the tray.

[0003] For example, see Figure 1 Hydrogen peroxide decomposes to produce carboxyl free radicals, which have strong oxidizing power. They can react with organic pigment molecules (tannic acid, furfural, tar, polyphenolic compounds, etc.) deposited on the tooth surface and in the dentinal tubules, oxidizing and decomposing them, thereby achieving the effect of teeth whitening.

[0004] Currently, commonly used teeth whitening trays generally use a fixed amount of whitening agent to whiten teeth, which results in lower whitening efficiency when tooth stains are severe. Summary of the Invention

[0005] In view of the problems existing in the prior art, this utility model provides a teeth whitening tray to improve the efficiency of teeth whitening.

[0006] To achieve the above objectives, this utility model provides a teeth whitening tray, which includes a U-shaped tray body forming a fitting groove to fit with a user's single jaw teeth; the tray body includes a first fitting part that fits with the anterior teeth, an electrolyte channel provided at the first fitting part, the electrolyte channel communicating with the fitting groove, and second fitting parts that fit with the posterior teeth formed on both sides of the width direction of the first fitting part; wherein, at least one electrode plate is provided on the side of the first fitting part near the teeth, and at least one vibration device is provided on the side of the second fitting part near the teeth.

[0007] In some embodiments, the first mating part further includes a driving assembly, which includes a driving controller electrically connected to the electrode sheet and the vibration device.

[0008] In some embodiments, the drive component further includes a battery and / or a charging interface.

[0009] In some embodiments, the driver component also includes a button.

[0010] In some embodiments, the button includes a light-emitting element.

[0011] In some embodiments, a plurality of contacts are formed on the side of the second mating portion near the mating groove, the plurality of contacts being used to abut and engage with the teeth.

[0012] In some embodiments, the plurality of contacts are located on the labial side of the teeth.

[0013] In some embodiments, a sealing structure is formed near the upper end of the mating groove in the dental tray body, and the sealing structure extends circumferentially along the mating groove.

[0014] In some embodiments, the sealing structure is a sealing strip.

[0015] In some embodiments, the vibration device is an ultrasonic generator.

[0016] In the embodiments of this application, by setting an electrolyte channel in the dental tray body, the entry and exit of the electrolyte in the dental tray can be effectively controlled, thereby enabling the reaction time to be controlled as needed, and the electrolyte to be replaced without removing the dental tray, thereby improving the efficiency of teeth whitening. The free radicals released by the electrode sheet electrolyzing the electrolyte decompose the organic pigment molecules on the tooth surface and in the dentinal tubules, restoring the teeth to their original color.

[0017] Furthermore, by installing a vibration device in the posterior tooth area, it is possible to effectively promote the removal of stubborn plaque on the posterior teeth, thereby exposing the tooth surface and enabling free radicals to quickly whiten the posterior teeth.

[0018] Therefore, based on the morphology and characteristics of the dental arch, this application arranges the electrode sheet and vibration device as described above, thereby effectively improving the whitening efficiency of both anterior and posterior teeth.

[0019] Furthermore, other functions and effects of this application will be described in detail with reference to the following figures and specific embodiments. Attached Figure Description

Detailed Implementation

[0021] To further illustrate the invention's purpose, technical features, and key advantages, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide further details of this application.

[0022] First, it is necessary to explain the background technology involved in the embodiments in order to fully understand the technical solution of this utility model.

[0023] Hydrogen peroxide (H2O2) is a mild oxidant that can increase its decomposition rate under the action of a low-frequency alternating electric field. The principle is that the alternating electric field can promote electron transfer and the formation of free radicals. In addition, compared with direct current, low-frequency alternating current can suppress the concentrated release of oxygen and hydrogen, that is, it will not lead to a significant water electrolysis reaction.

[0024] Furthermore, the technical solution of this application will be described below through specific embodiments.

[0025] Example 1

[0026] Please see Figure 2A and 2B This is a schematic diagram of the axial structure of the teeth whitening tray in Embodiment 1. The teeth whitening tray in Embodiment 1 includes a tray body 100, which is generally U-shaped. During use, it wraps around the user's upper or lower teeth through its inwardly recessed fitting groove 101. It can be understood that, as seen in... Figure 2A When the upper teeth are enclosed, the two ends of the mating groove 101 are closed, as seen in... Figure 2B When the lower dentition is included, the two ends of the fitting groove 101 form an open state, depending on the internal anatomical structure of the oral cavity. The dental tray body 100 is made of soft or hard transparent plastic.

[0027] Specifically, the denture body 100 includes a first mating part 110 and a second mating part 120. The first mating part 110 is mainly responsible for the delivery and electrolysis control of the electrolyte, and it primarily covers the anterior teeth area. Figure 3 The bottom of the first mating part 110 is provided with an electrolyte channel 111. In use, the electrolyte channel 111 is connected to a bidirectional micro electric pump through a pipeline. The bidirectional micro electric pump can be connected to an electrolyte container or a waste liquid container through a pipeline. During the whitening process, the user can control the bidirectional micro electric pump and the connection method of the pipeline to inject and remove the electrolyte in the mouth. The color of the teeth can be observed without removing the dental tray body 100 so as to decide whether to continue whitening.

[0028] The first mating part 110 is provided with an electrode plate 112 on the labial side of the tooth arch. When working, the electrode plate 112 releases low-frequency alternating current to electrolyze the electrolyte, thereby releasing hydroxyl radicals (OH) and continuously destroying organic pigment molecules deposited on the tooth surface and in the dentinal tubules. Since the focus of whitening is the anterior tooth area, by setting the electrode plate 112 in the anterior tooth area, the whitening efficiency of the anterior tooth area can be effectively improved.

[0029] Understandably, the concentration of hydrogen peroxide in the electrolyte should be ≤5%, and small amounts of potassium nitrate or sodium fluoride can be added to alleviate tooth sensitivity.

[0030] Furthermore, the second mating part 120 is mainly used for wrapping the posterior teeth area. The whitening requirements for the posterior teeth area are not as high as those for the anterior teeth area. However, since the posterior teeth area is an area that most people clean and maintain poorly, it is easy for thick plaque to accumulate. Therefore, the second mating part 120 is equipped with an ultrasonic generator 122 and a contact 121. Specifically, the contact 121 is located on the labial side of the tooth. The ultrasonic generator 122 vibrates and drives the contact 121, which can promote the removal of plaque in the posterior teeth area during the whitening process, so as to facilitate the whitening of the teeth.

[0031] Example 2

[0032] Please see Figure 5 The difference between the dental tray body 100 in this embodiment and that in embodiment 1 is that a sealing strip 102 is formed along the upper end of the mating groove 101. The sealing strip 102 can reduce the leakage of electrolyte during the operation of the dental tray, thereby reducing the sensitivity of other tissues in the oral cavity.

[0033] Example 3

[0034] Please see Figure 6 This is a system block diagram of a teeth whitening tray, which can be applied to the teeth whitening tray in Embodiment 1 or 2. It mainly includes a drive assembly 200, which includes a drive controller 201, a battery 202 and / or a charging interface 203 disposed at the first mating part 110. The drive controller 201 is mainly used to control the working state of the electrode plate 112 and the ultrasonic generator 122, and controls the start and stop of the whitening operation through the button 204. The button 204 is provided with a light-emitting element 205, which can emit different lights to indicate different working levels or working states.

[0035] It is understood that the aforementioned drive controller 201 can be a circuit board with control functions, such as a micro relay control board or an MCU main control board.

[0036] Therefore, in summary, the teeth whitening tray provided in this application realizes the injection and discharge of electrolyte through the electrolyte channel 111. After the electrolyte is injected, the working state of the tray is controlled by the button 204. During the whitening process, the electrode plate 112 in the anterior tooth area transmits low-frequency alternating current to continuously electrolyze the electrolyte, thereby releasing carboxyl free radicals in the electrolyte and effectively whitening the tooth surface. At the same time, the ultrasonic generator 122 and the contact 121 in the posterior tooth area can effectively separate the plaque attached to the posterior teeth from the tooth body, thereby improving the whitening efficiency of the posterior teeth area and making the whitening effect of the anterior and posterior teeth areas tend to be balanced.

[0037] It is understood that in this application, "at least one" means a quantity of one or more, and "more than one" means a quantity of two or more.

[0038] In this application, directional terms such as "upper", "lower", "left", "right", "inner", "outer", "length direction", "width direction", and "height direction" only indicate the relative relationships expressed in the accompanying drawings and are not intended to limit this utility model.

[0039] The features in the above embodiments can be freely combined. In order to express the solution concisely, this application does not describe all combinations of technical features that can achieve the purpose of the present invention. Therefore, without violating the principle and spirit of the present invention, the scope of the present invention is defined by the claims.
