Description

Technical Field

[0001] This utility model relates to the field of teeth whitening equipment technology, and in particular to a device for applying teeth whitening gel. Background Technology

[0002] Teeth whitening gel is a commonly used product in oral care. It is usually applied to the surface of teeth and then exposed to light through a whitening device to achieve a whitening effect. Currently, some whitening gel products on the market may contain a mixture of two or more active ingredients.

[0003] However, after mixing, the active ingredients in these multi-component gels may gradually react or decompose over time, leading to a decrease or even loss of their whitening effect. If the gel is pre-mixed during production, a considerable amount of time may have passed from manufacturing, transportation, and storage to end-user use, posing a risk of gel deterioration. Therefore, how to mix the gel instantly and evenly at the time of use and conveniently apply it to teeth is a problem that urgently needs to be solved in existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a teeth whitening gel application device, which aims to solve the problem that teeth whitening gel may fail due to pre-preparation in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a teeth whitening gel application device, the teeth whitening gel application device comprising: The outer cylinder has two chambers inside, each chamber being used to store two different gel components of equal volume. A piston that is slidably fitted within the cavity of the outer cylinder; A push rod, one end of which is connected to the piston; A spiral mixer, which is detachably mounted to the outlet end of the outer cylinder; The application end is located at the outlet of the spiral mixer and is used to apply the mixed gel to the tooth surface. The application end includes an angled brush that facilitates secondary stirring of the gel components during application.

[0006] In one embodiment, the two chambers have the same cross-section and volume.

[0007] In one embodiment, the spiral mixer is fixed at the outlet position of the outer cylinder by a connecting sleeve.

[0008] In one embodiment, the axis of the brush forms an angle of 40° to 50° with the axis of the outer cylinder.

[0009] In one embodiment, the outer cylinder has a flat overall structure.

[0010] In one embodiment, a sealing dust cap is also included, which can be installed at the outlet of the outer cylinder to seal the chamber when the spiral mixer is removed from the outer cylinder.

[0011] The above-described technical solutions in the embodiments of this utility model have at least the following technical effects or advantages: The teeth whitening gel application device provided in this embodiment stores two different gel components in two independent chambers. During use, the gel is extruded proportionally via a pusher and instantly mixed by a spiral mixer. A brush further agitates the gel during application, ensuring uniform mixing and application to the tooth surface. This avoids the risk of gel failure due to pre-preparation and prolonged storage, ensuring effective whitening. Furthermore, the flat outer cylinder facilitates gripping, and the brush's angled design (preferably 45°) better suits user habits, enhancing ease of use. Finally, a sealed dust cap seals the chambers when not in use, effectively preventing deterioration of the internal components upon contact with air, extending the product's shelf life, and facilitating packaging, storage, and transportation.

[0019] Please see Figures 1 to 2 This application provides a teeth whitening gel application device including an outer cylinder 1, a push rod 3, two pistons 2 (typically made of rubber) located at the front end of the push rod 3, a spiral mixer 4, and an application end 5. The outer cylinder 1 has two parallel, independent chambers 11 inside. These two chambers 11 have the same cross-sectional area and volume, and are used to store two different whitening gel ingredients respectively. The overall shape of the outer cylinder 1 is designed to be flat, which is more ergonomic and allows the user to hold it more conveniently and stably during application.

[0020] At the outlet end of the outer cylinder 1, a spiral mixer 4 is detachably installed via a connecting sleeve 5. The outlet end of the spiral mixer 4 is equipped with a brush, which serves as an application end 5. For ease of operation, the axis of the brush is designed to form an angle of 40° to 50° with the axis of the outer cylinder 1, with an optimal angle of 45°.

[0021] When needed, the user simply pushes the push rod 3 forward, which drives the two pistons 2 forward synchronously. Under the pressure of the pistons 2, the two gel components stored in the two chambers 11 are extruded evenly in equal proportions. These two components then enter the spiral mixer 4, where the spiral blade structure inside the mixer ensures that the two components are thoroughly and evenly mixed as they flow forward, forming the desired whitening gel. The mixed gel is then dispensed from the brush at the end. The user simply holds the device, aligns the brush with the outer surface of the teeth, and moves it repeatedly to complete the application. After application, the gel can be irradiated with a whitening device to activate its whitening function.

[0022] Optionally, the outer tube 1 is made of transparent PC material with graduations so that users can observe the remaining amount of whitening gel in the outer tube 1 and control the amount applied each time.

[0023] Please see Figure 3 The figure illustrates the device in its condition during transport or storage. To prevent the gel component within chamber 11 from deteriorating due to air contact during prolonged periods of non-use, the device is also equipped with a sealing dust cap 7. During packaging, transport, or routine storage, the user can remove the entire mixing and application assembly, including the connecting sleeve 5, the spiral mixer 4, and the brush, from the outer cylinder 1. The sealing dust cap 7 is then installed at the outlet of the outer cylinder 1, effectively sealing the openings of both chambers 11 and providing a dual function of dust prevention and preventing component deterioration.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
