A convenient toothpick structure

Abstract

This invention discloses a convenient toothpick structure, including a toothpick body and an extended handle. The toothpick body includes a handle portion and a flexible strip. The flexible strip is conical and has a spiral tooth structure along its circumferential direction. The front end of the extended handle can be connected to the handle portion via a connecting mechanism. The rear end of the handle portion has a cavity that can accommodate the flexible strip. This invention also discloses another structure, where the flexible strip has a flexible bar structure along its circumferential direction. The flexible bar structure gradually lengthens along the rear direction of the flexible strip, making it also conical. This invention replaces the traditional hard toothpick head with a conical flexible strip structure, combined with a spiral tooth or a gradually changing flexible bar structure. This ensures that the toothpick can reach deep into the gaps between teeth to clean food residue, while avoiding the problem that the sharp head of a traditional hard toothpick can easily injure the gums and scratch the oral mucosa.

Description

Technical Field

[0001] This invention relates to the field of oral hygiene products, and more particularly to a convenient toothpick structure. Background Technology

[0002] Toothpicks, as the most commonly used oral hygiene tool in daily life, have a history of use for hundreds of years. Currently, most mainstream toothpick products on the market are single, straight-handled wooden or bamboo toothpicks, with some products made of one-piece plastic. These traditional toothpicks have several undeniable drawbacks in actual use: First, the sharp tips and relatively short overall length of traditional toothpicks make it difficult for users to control the depth and force applied when holding them, easily injuring the gums. Long-term use may also lead to oral problems such as gum recession and widening of gaps between teeth. Second, the smooth toothpick handle is prone to slipping and incomplete cleaning when cleaning tightly packed food debris, especially in the gaps between the back teeth, where the insufficient length of ordinary toothpicks makes it difficult for users to apply force, significantly reducing the cleaning effect.

[0003] As people's awareness of oral health continues to improve, some alternative products such as dental floss and dental floss picks have appeared on the market. However, these products also have obvious limitations: dental floss has a high learning curve, and it is difficult for elderly users and children to master it and independently clean the dental area; ordinary dental floss picks have a limited cleaning range and are not ideal for cleaning soft plaque and dental plaque attached between teeth. Moreover, most products are for single use, and the overall cost of long-term use is high.

[0004] Currently, there are some patented toothpick products with extended handles, but most of these products have unreasonable structural designs. The toothpick heads lack a dedicated flexible cleaning structure; either they are too hard and easily damage the oral mucosa, or the cleaning teeth are poorly arranged and cannot adapt to different sized gaps between teeth. Furthermore, these products have poor storage properties; the exposed sharp heads not only easily puncture the packaging but also easily collect dust and bacteria during transport, posing significant hygiene risks. In addition, most existing products have limited functions and cannot be used in conjunction with the widely available electric toothbrushes, making it difficult to achieve more efficient deep cleaning through electric drive and failing to meet users' diverse oral hygiene needs.

[0005] A review of existing patents and market products reveals several key technological gaps in current toothpick products: First, the lack of a design that combines flexible cleaning teeth with a retractable structure compromises both safety during cleaning and hygienic storage for portability. Second, the structural parameters of the cleaning teeth are not specifically optimized; the tooth height and spacing either easily scratch gums or fail to effectively trap food debris, resulting in low cleaning efficiency. Third, the products lack adaptability; they lack extendable handles that can be flexibly attached to different cleaning areas and do not have a connection structure with universal electric toothbrushes, hindering the expansion of electric cleaning functionality and making it difficult to balance the convenience of manual operation with the efficiency of electric cleaning.

[0006] Therefore, in summary, developing a convenient toothpick structure that is structurally sound, effective in cleaning, safe to use, and easy to carry and store has become a pressing technical problem to be solved in the field of oral hygiene tools. Summary of the Invention

[0007] This invention addresses the aforementioned problems by proposing a convenient toothpick structure, primarily used to solve the problems mentioned above.

[0008] To achieve the above technical objectives, the present invention adopts a convenient toothpick structure, including a toothpick body and an extended handle; the toothpick body includes a handle portion and a flexible strip, the flexible strip is conical, and the flexible strip has a spiral tooth structure along its circumferential direction; the front end of the extended handle can be connected to the handle portion through a connecting mechanism, and the rear end of the handle portion has a cavity that can accommodate the flexible strip.

[0009] Preferably, the tooth height of the helical tooth structure is 0.1-0.5 mm and the tooth pitch is 0.3-1 mm.

[0010] More preferably, the spiral tooth structure is rotated in either left or right.

[0011] The present invention also introduces another convenient toothpick structure, including a toothpick body and an extended handle; the toothpick body includes a handle portion and a flexible strip, the flexible strip is conical, and the flexible strip is provided with a flexible barb structure along the circumferential direction; the flexible barb structure gradually lengthens along the rear direction of the flexible strip, so that the flexible barb structure is also a conical structure on the flexible strip; The front end of the extended handle can be connected to the handle part through a connecting mechanism, and the rear end of the handle part has a cavity that can accommodate the flexible strip.

[0012] Furthermore, a baffle structure is provided between the handle and the flexible strip, and the handle, flexible strip and baffle structure are integrally injection molded structures.

[0013] Furthermore, the inner wall of the extended handle is provided with anti-slip texture to increase friction with the soft strip.

[0014] Furthermore, the handle portion and the extended handle are connected by a threaded connection, a snap-fit ​​connection, or a magnetic connection.

[0015] The structure of the present invention also includes an electric toothbrush body, and the toothpick body can be combined with the electric toothbrush body to form a vibrating or high-speed rotating electric toothpick structure.

[0016] Furthermore, the electric toothbrush body is equipped with a driving device, which can drive the soft strip to vibrate or rotate. The vibration frequency is 50-200Hz, and the rotation speed of the soft strip is 1000-5000r / min.

[0017] Furthermore, the length of the extended handle is 4-10cm, and the diameter of the cavity is 0.1-0.3mm larger than the maximum diameter of the flexible strip.

[0018] After adopting the above-mentioned technical improvements, the present invention has the following advantages: 1. This invention replaces the traditional hard toothpick head with a tapered soft strip structure, combined with a spiral tooth or a gradient soft bar structure. While ensuring that it can reach deep into the gaps between teeth to clean residue, it avoids the problem that the sharp head of the traditional hard toothpick can easily puncture the gums and scratch the oral mucosa. 2. The spiral tooth structure of this invention, with targeted parameter optimization, has a tooth height controlled at 0.1-0.5mm and a tooth spacing controlled at 0.3-1mm. This allows it to reach into gaps of varying widths, effectively trapping and removing impacted food debris and plaque without slipping or causing incomplete cleaning. At the same time, the gradually elongated soft barb structure of this invention can also massage the gums around the gaps during cleaning, achieving both cleaning and gum protection effects. 3. The toothpick body of the present invention has a special cavity structure at the rear end of the handle. After use, the soft strip can be directly inserted into the cavity in reverse to completely hide the cleaning part, avoiding the exposed structure from puncturing the packaging bag and getting contaminated with dust and bacteria, making it more hygienic and safe to carry. 4. The toothpick body of the present invention can be directly combined with the body of a widely used electric toothbrush. With the help of the internal drive device of the electric toothbrush, it can achieve rotational cleaning. There is no need to purchase a special electric toothpick device. It can achieve deep cleaning between teeth by means of high frequency vibration or rotation, and improve the efficiency of residue removal. 5. Most of the overall structure of this invention can be integrally injection molded, which is simple to produce, does not require complicated assembly procedures, and has low manufacturing costs. At the same time, the baffle structure can limit the movement during use, preventing the soft strip from going too deep into the oral cavity, and further improving the safety of use.
