Its simple structure requires no electronic components and is convenient to use.

Description

Baby toothbrush with moisture sensing time-display structure Technical Field

[0001] This invention relates to a toothbrush structure, particularly to a toothbrush structure for infants and toddlers that has a water inlet hole in the brush neck and a reaction chamber and a color developing medium inside the brush handle, so that external liquid can be introduced into the reaction chamber through a water guiding channel to produce a color change. Prior Technology

[0002] A typical baby toothbrush consists of a brush head, a brush neck, and a handle, and its function is to provide oral cleaning. However, after prolonged use, the bristles may wear down, become bent, or pose hygiene concerns, requiring regular replacement. In practice, the timing of replacement is often determined by the user themselves or estimated based on experience, lacking clear, structured guidelines.

[0003] There are also toothbrush designs on the market with a fadeable coating on the bristles, allowing the bristles to gradually fade as a reference for replacement. However, this type of design mainly addresses color changes caused by bristle wear or washing, and does not involve the configuration of internal liquid delivery and color-developing structures.

[0004] Some oral hygiene products use electronic timing or vibration reminders to indicate usage time, but such designs require batteries or electronic components, making the structure more complex and increasing the cost.

[0005] Therefore, existing toothbrush structures do not yet include a design that allows liquid to be introduced into the brush neck or handle to create cumulative color changes, thus providing a visual reminder for replacement. There is still room for improvement. Summary of the Invention

[0006] The main purpose of this invention is to provide an infant toothbrush with a moisture-sensing timing and color-displaying structure, which allows liquids that come into contact with the toothbrush during use to be introduced into the reaction chamber inside the handle, and the color change is displayed on the external viewing surface through the diffusion of the color-displaying medium, serving as a visual cue for when to replace the toothbrush, thus improving the problem of traditional toothbrushes lacking a structural reminder mechanism.

[0007] To achieve the above objectives, the present invention comprises: a brush head, a brush handle, and a brush neck disposed between the brush head and the brush handle; wherein, the brush neck is provided with a water inlet at a predetermined position; a reaction chamber is formed inside the brush handle, and a color developing medium is disposed inside the reaction chamber; the water inlet communicates with the reaction chamber through a water guiding channel, so that external liquid can be introduced into the reaction chamber; and the brush handle is provided with a viewing part, which is correspondingly disposed with the reaction chamber.

[0008] Therefore, when the toothbrush comes into contact with liquid during brushing or rinsing, the liquid can be introduced into the reaction chamber through the water inlet and the water channel, causing the color developing medium to gradually diffuse within the reaction chamber and display the color change through the viewing section, thus providing the user with a visual reminder to replace the toothbrush.

[0009] In this embodiment of the invention, the water guiding channel can be a narrow, elongated throttling channel to limit the liquid introduction speed; the water guiding channel can also be a capillary structure to allow the liquid to be introduced stably; the color developing medium can be disposed in a storage tank and can be a solid dye or a high-concentration dyeing solution; the viewing part can be a transparent or semi-transparent window; the reaction chamber can also be a narrow, elongated chamber to allow the color development to gradually diffuse along the length of the chamber.

[0010] Based on the above description, the features and effects of this novel invention are briefly summarized as follows:

[0011] 1. The structure of the brush neck with water inlet holes and water channels connecting to the reaction chamber provides a clear structural path for liquid introduction, rather than relying solely on material discoloration.

[0012] Second, through the configuration of the reaction chamber and the color developing medium, the color changes can be clearly identified on the external viewing part of the brush handle, forming an intuitive visual cues.

[0013] Third, this new type of device does not require electronic components or batteries, and its structure is relatively simple, which is beneficial to manufacturing and safe use.

[0014] Fourth, through the cumulative effect of liquid introduction and color diffusion, toothbrush replacement judgment has a structured basis, improving the convenience of use and management. Simple Explanation of the Diagram

Figure 3: Schematic diagram of the cross-section of the present invention after color development. Figure 4: A diagram illustrating a prompt for the user to change their toothbrush. Implementation

[0016] Please refer to Figures 1 to 4. The present invention, a baby toothbrush with a moisture-sensing timing and color-displaying structure, includes a handle 10, a brush head 20, and a brush neck 30. The brush head 20 is disposed at one end of the handle 10, and the brush head 20 is provided with a plurality of bristles 21; the brush neck 30 is disposed between the brush head 20 and the handle 10.

[0017] As shown in Figures 1 to 3, the brush neck 30 has a water inlet 31 at a predetermined position. The brush handle 10 forms a reaction chamber 40 inside, and a color developing medium 41 is disposed inside the reaction chamber 40. The water inlet 31 is connected to the reaction chamber 40 via a water guiding channel 32, so that external liquid can be introduced into the water guiding channel 32 through the water inlet 31 and further into the reaction chamber 40.

[0018] A viewing section 50 is provided on the outer side of the brush handle 10. The viewing section 50 is correspondingly provided to the reaction chamber 40, so that the state inside the reaction chamber 40 can be observed from the outside.

[0019] In this embodiment, the water guiding channel 32 can be a narrow and elongated channel to create a throttling effect; the water guiding channel 32 can also be a capillary structure to stably introduce liquid into the reaction chamber 40.

[0020] The color developing medium 41 can be disposed in a storage tank 42, which is disposed within the reaction chamber 40. The color developing medium 41 can be a solid dye or a high-concentration dyeing solution.

[0021] The reaction chamber 40 can be a long and narrow chamber, allowing the color to diffuse gradually along the length of the chamber. The viewing section 50 can be a transparent or semi-transparent window, and can be provided with patterns or text markings that will appear after the color is developed.

[0022] When the toothbrush comes into contact with liquid during brushing or rinsing, the liquid can be introduced into the water channel 32 through the water inlet 31 and further into the reaction chamber 40. After the liquid enters, the color developing medium 41 dissolves and diffuses within the reaction chamber 40. With repeated use, the distribution of the color developing medium 41 within the reaction chamber 40 gradually changes, and this color change is displayed through the viewing section 50, allowing the user to determine the toothbrush's condition and use it as a reference for replacement.

[0023] In summary, this novel baby toothbrush with a moisture-sensing, timing, and color-coding structure has the following characteristics and effects:

[0024] 1. Through the water inlet 31 provided on the brush neck 30 and the water guiding channel 32 connected thereto, external liquid can be introduced into the reaction chamber 40 according to a predetermined path, forming a clear structural water guiding mechanism, rather than relying solely on the discoloration of the material surface. The structural relationship is clear and stable.

[0025] Second, the color developing medium 41 provided in the reaction chamber 40 causes the liquid to dissolve and diffuse after it is introduced, and the color change is displayed through the viewing part 50 located on the outside of the brush handle 10, so that the user can intuitively identify the use status of the toothbrush.

[0026] Third, the water channel 32 can be a narrow channel or a capillary structure, so that the liquid introduction has a slow-release characteristic, which helps to form a cumulative color development effect and improves the stability of replacement judgment.

[0027] Fourth, the reaction chamber 40 can be a long and narrow chamber, so that the color gradually diffuses along the length of the chamber, and can be combined with the viewing part 50 to set patterns or text markings, so that the display effect is clearer.

[0028] V. This new type of device does not require electronic components or batteries. The overall structure is mainly composed of a brush handle 10, a brush neck 30, a water channel 32, and a reaction chamber 40. The structure is relatively simple, which is conducive to manufacturing, assembly and safe use.
