Description

Technical Field

[0001] This utility model relates to the technical field of oral cleaning appliances, and in particular to a multifunctional dental floss with a double-line cleaning structure and a brush head. Background Technology

[0002] In oral care, dental floss is a commonly used cleaning tool to remove food debris and plaque from between teeth and in the gingival sulcus. Traditional dental floss or toothpicks have a relatively simple structure, usually using a single thread design, which can only adapt to gaps of a fixed width. The cleaning effect varies greatly depending on the size of the gap. For example, thicker single threads cannot reach narrow gaps, while thinner single threads are prone to bending and deformation when cleaning wider gaps, resulting in incomplete cleaning.

[0003] Furthermore, traditional dental floss often features a single brush head or no brush head design at the tip, resulting in a limited cleaning area and insufficient cleaning power for the tooth surface and gingival sulcus, failing to meet users' needs for deep cleaning. Additionally, the connection angle between the tail and the arch of existing dental floss is typically a fixed right angle or obtuse angle, without considering compatibility with production molds. This leads to poor mold versatility and an uncomfortable grip angle during use, negatively impacting the user experience.

[0004] Therefore, there is an urgent need for a dental floss that can adapt to different gap widths between teeth, has efficient cleaning capabilities, and has a reasonable structural design, in order to solve the above-mentioned problems in existing technologies. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a multifunctional dental floss with a dual-line cleaning structure and a brush head. The bow section adopts a dual-track structure with parallel thick and thin lines, with a width difference of 0.4-0.8mm, which can adapt to different interdental spaces. The tip section has eight rows of radial brush heads with an included angle of 45°, which expands the cleaning area and enhances the cleaning power. The tail section is inclined at a 120°-150° angle to the bow section, which is ergonomic and adaptable to molds, thus improving production stability.

[0007] To achieve the above objectives, this utility model proposes a multifunctional dental floss with a dual-thread cleaning structure and brush heads, comprising an arch section, a tip section, and a tail section. The arch section is composed of parallel and inseparable thick and thin threads. The width of the thick thread is 0.8-1.2 mm, and the width of the thin thread is 0.3-0.6 mm, with a width difference of 0.4-0.8 mm. The tip section has eight rows of brush heads at its end, arranged radially at equal angles around the tip, with an included angle of 45° between adjacent rows. The connection between the tail section and the arch section forms an inclination angle α, which is 120°-150°. The arch section, tip section, and tail section are integrally formed.

[0008] This utility model discloses a multifunctional dental floss with a dual-line cleaning structure and brush head. The bow section adopts a dual-track structure with parallel thick and thin lines, with a width difference of 0.4-0.8mm, to adapt to different interdental spaces. The tip section has eight rows of radial brush heads at a 45° angle, which expands the cleaning area and enhances the cleaning power. The tail section is inclined at a 120°-150° angle to the bow section, which conforms to ergonomics and is compatible with molds, improving production stability.

[0009] In addition, the multifunctional dental floss with a dual-line cleaning structure and brush head proposed in the above application may also have the following additional technical features:

[0010] Specifically, the bow section is composed only of thick and thin wires, with a spacing of 0.5-1.0 mm between the thick and thin wires.

[0011] Specifically, each row of bristles in the eight-row brush head is made of a flexible material to enhance the cleaning effect.

[0012] Specifically, the dental floss has an overall length of 60-80mm and is made of biodegradable plastic.

[0013] The advantages of this invention compared to existing technologies are as follows:

[0014] (1) The bow section uses parallel thick and thin threads to form a dual-track cleaning structure. The difference in width between the thick and thin threads is 0.4-0.8mm, which can effectively clean wide and narrow gaps between teeth respectively, solving the problem of insufficient applicability of traditional single-thread dental floss.

[0015] (2) The tip is equipped with eight rows of radially distributed brush heads with an angle of 45° between adjacent brush heads, forming a 360° three-dimensional cleaning area. Compared with traditional single-row or few-row brush heads, the cleaning area is increased and the cleaning power is stronger, which can effectively remove stubborn stains on the tooth surface and in the gingival sulcus.

[0016] (3) The tail and the bow form a 120°-150° tilt angle, which optimizes the ergonomic angle when holding and makes it more comfortable to exert force when using. At the same time, this angle is precisely matched with the special mold, which improves the adaptability and stability of the mold in the production process.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0024] The following description, in conjunction with the accompanying drawings, describes a multifunctional dental floss with a brush head and a dual-line cleaning structure, according to an embodiment of the present invention.

[0025] like Figures 1-3 As shown in the figure, a multifunctional dental floss with a brush head and a dual-line cleaning structure according to an embodiment of the present invention includes an arch section 1, a tip section 2, and a tail section 3.

[0026] It is understandable that the dental floss adopts a one-piece molded structure to ensure a stable connection between the arch 1, tip 2, and tail 3, avoiding the risk of parts falling off during use. The arch 1 consists of parallel and inseparable thick and thin threads 11 and 12. When used by the user, the width of the thick thread 11 is 0.8-1.2mm, and the width of the thin thread 12 is 0.3-0.6mm. The 0.4-0.8mm width difference between the two can precisely adapt to different widths of interdental spaces. Wider interdental spaces are cleaned with the thick thread 11, which effectively scrapes away food debris due to its larger cross-sectional area; while narrower interdental spaces are cleaned with the thin thread 12, which reaches deeper into the interdental spaces due to its smaller size.

[0027] The eight rows of brush heads 21 at the tip 2 are radially distributed at equal angles around the tip 2, with the angle between adjacent rows of brush heads being 45°. When cleaning the tooth surface and gingival sulcus, the user can rotate the dental floss to allow the brush heads 21 to cover the cleaning area in 360°. Each row of brush heads can reach different parts of the interdental spaces and gingival sulcus, significantly improving the cleaning area and intensity compared to traditional single-row brush heads.

[0028] The connection between the tail section 3 and the bow section 1 forms a tilt angle α of 120°-150°. When the user holds the tail section 3, this angle conforms to the ergonomic design, making the force application more natural and comfortable. In the production process, this specific angle is precisely matched with the demolding angle of the injection mold, which facilitates the formation and demolding of dental floss in the mold, effectively improving production efficiency and product quality.

[0029] It should be noted that because the thinner floss 12 is 0.3-0.6mm wide, its small size and thinness, combined with its placement on the outer side, allow for easier and more targeted insertion into narrower interdental spaces. For example, when cleaning areas with relatively tight interdental spaces, such as molars, the user does not need to make any special adjustments; the thinner floss 12, due to its outer position, can quickly insert into the interdental space, avoiding the problem of difficulty in reaching the space caused by the thicker floss 11 contacting the interdental space first. Conversely, when cleaning wider interdental spaces, the user can adjust the floss angle so that the thicker floss 11 contacts the interdental space, utilizing its 0.8-1.2mm width for cleaning. The thinner floss 12, being on the outer side, does not interfere with the cleaning process of the thicker floss 11. Together, they further enhance the cleaning efficiency and applicability of the floss for different interdental space widths.

[0030] In one embodiment of this utility model, such as Figures 1-3 As shown, the bow 1 is composed of only a thick wire 11 and a thin wire 12, with a spacing of 0.5-1.0 mm between the thick wire 11 and the thin wire 12.

[0031] It is understandable that the bow section 1 consists only of a thick wire 11 and a thin wire 12, making the overall design simple and the function clearly defined. The distance between the two wires is set at 0.5-1.0mm, which ensures that the thick wire 11 and the thin wire 12 maintain independent cleaning functions while also preventing them from interfering with each other during use.

[0032] When using dental floss to clean their mouths, users can flexibly choose the cleaning method according to the width of the gaps between their teeth. For wider gaps, the thicker thread 11 is aligned with the gap, and its 0.8-1.2mm width allows for extensive contact with the inner walls of the gap, effectively scraping away attached food debris and plaque. For narrower gaps, the thinner thread 12, with its 0.3-0.6mm size and a spacing of 0.5-1.0mm, can be easily inserted to clean deep into the gap. Simultaneously, the parallel design of the two threads allows both the thicker thread 11 and the thinner thread 12 to work on adjacent gaps of different widths during cleaning, eliminating the need to frequently change the application point and greatly improving cleaning efficiency. Furthermore, this simple dual-thread design and precise spacing make the floss easier to shape and control in the manufacturing process, ensuring that each piece of floss consistently performs its cleaning function.

[0033] In one embodiment of this utility model, such as Figures 1-3 As shown, each row of bristles in the eight-row brush head 21 is made of a flexible material to enhance the cleaning effect.

[0034] It is understandable that the eight rows of brush heads 21 at the tip 2 are designed with flexible materials, which greatly improves the cleaning experience and effect. The bristles of each row of brush heads 21 are made of flexible silicone, which has good flexibility and elasticity.

[0035] During the cleaning process, when the user inserts the brush head 21 of the dental floss tip 2 deep into the tooth surface and gingival sulcus, the flexible bristles closely conform to the irregular curves of the teeth, effectively reaching the fine grooves on the enamel surface and the gaps at the junction of the gum and teeth. Compared to hard bristles, the flexible material will not damage the gum tissue due to excessive force, and can gently remove attached plaque and food debris even when cleaning sensitive areas such as the gingival sulcus. At the same time, the flexibility of the bristles allows them to deform under pressure, thereby increasing the contact area with the cleaning area, further enhancing the cleaning effect, ensuring that the tooth surface and gingival sulcus are thoroughly cleaned, achieving efficient cleaning while taking into account oral safety and comfort.

[0036] In one embodiment of this utility model, such as Figures 1-3 As shown, the overall length of the dental floss is 60-80mm, and the material is biodegradable plastic.

[0037] It's understandable that the overall length of the dental floss is set at 60-80mm. This size is convenient for users to hold while ensuring sufficient cleaning length. When using it, the appropriate length can easily cover all areas of the mouth, whether it's the front or back teeth, without the need for frequent adjustments to the floss position. For example, when cleaning the molars, a length of about 70mm allows it to naturally bend and reach deep into the mouth, ensuring a smooth cleaning process.

[0038] The floss is made of biodegradable plastic, preferably polylactic acid (PLA) or starch-based biodegradable materials. During production, all components (bow section 1, tip 2, and tail 3) are integrally molded using injection molding. After use, the biodegradable plastic dental floss gradually decomposes into water and carbon dioxide in the natural environment through the action of microorganisms, avoiding the environmental pollution problems caused by traditional plastic dental floss. At the same time, the biodegradable plastic material itself has good toughness and strength, ensuring that the structure of the thick and thin floss 11 of the bow section 1, the brush head 21 of the tip 2, and the tail 3 will not easily break during use, providing users with a stable and reliable cleaning experience.

[0039] Specifically, in actual use, when a user uses this dental floss, they first hold the tail end 3, utilizing its comfortable grip angle of 120°-150° to guide the floss to the oral cavity. Observe the width of the gaps between teeth. If the gaps are wide, align the thicker thread 11 of the arch 1 with the gap, using its 0.8-1.2mm width to adhere extensively to the inner wall of the gap and scrape back and forth to remove food debris. If the gaps are narrow, the thinner thread 12 on the outer side, due to its 0.3-0.6mm size and a reasonable distance of 0.5-1.0mm from the thicker thread 11, will automatically and preferentially insert into the deeper parts of the gap for cleaning.

[0040] When cleaning the tooth surface and gingival sulcus, rotate the floss to allow the eight rows of brush heads 21, arranged radially at a 45° angle from the tip 2, to fully cover the cleaning area. Each row of bristles, made of flexible silicone, closely conforms to the irregular curves of the teeth, reaching deep into the fine grooves of the enamel and the gingival crevices, gently and thoroughly removing plaque without damaging the gums. Throughout the cleaning process, the floss, with its suitable length of 60-80mm, covers all areas of the mouth without frequent adjustments, achieving a comprehensive clean from between teeth to the tooth surface and gingival sulcus. Finally, the biodegradable plastic floss used will not pollute the environment.

[0041] In summary, the multifunctional dental floss with a brush head and a dual-line cleaning structure of this utility model adopts a dual-track structure with parallel thick and thin lines in the bow section, with a width difference of 0.4-0.8mm, to adapt to different interdental spaces. The tip has eight rows of radial brush heads at a 45° angle, which expands the cleaning area and enhances the cleaning power. The tail is inclined at a 120°-150° angle to the bow section, which is ergonomic and adaptable to molds, improving production stability.
