Description

Technical Field

[0001] The utility model relates to the technical field of teeth cleaning products, in particular to a toothpick. Background Art

[0002] Current daily dental cleaning products primarily include toothpicks, dental floss, toothbrushes, oral irrigators, and dental gauze wipes. Toothpicks are inexpensive and can remove food debris from between teeth or cavities, but their cleaning range is limited. They cannot reach debris on the tooth surface or in the gingival sulcus, and often cause gum bleeding and widening of the gaps between teeth. Dental floss can better remove food debris and debris from between teeth, but it also cannot reach the tooth surface or the gingival sulcus, and often gets stuck. Toothbrushes are the most commonly used daily dental cleaning product, but they are inconvenient to carry around and cannot be used for cleaning after every meal. They also require a clean water source, making them impractical when traveling or camping where water is unavailable. Oral irrigators are expensive and bulky, making them difficult to carry around. They require access to a water source and use them with a water jet, resulting in weak and incomplete cleaning. Dental gauze wipes are typically used for cleaning infants and young children's teeth, but they cannot reach between teeth or the gingival sulcus and are also inconvenient to use.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] Example 1:

[0022] like Figure 1 As shown, the utility model provides a toothpick, including a toothpick rod 1 and a first piece 2, the first piece 2 is connected to the toothpick rod 1, the first piece 2 is a concave arc plane, the front end of the first piece 2 is provided with a first arc segment 21 in an outward convex arc shape, the rear end of the first piece 2 is provided with a second arc segment 22, a third arc segment 23 is connected between one end of the first arc segment 21 and one end of the second arc segment 22, and a fourth arc segment 24 is connected between the other end of the first arc segment 21 and the other end of the second arc segment 22.

[0023] Preferably, the first toothpick piece 2 is symmetrical about the central longitudinal axis of the toothpick rod 1.

[0024] Preferably, the first arc segment 21 is symmetrical about the central longitudinal axis of the toothpick rod 1, the second arc segment 22 is symmetrical about the central longitudinal axis of the toothpick rod 1, and the third arc segment 23 and the fourth arc segment 24 are symmetrically arranged with the central longitudinal axis of the toothpick rod 1 as the axis.

[0025] The toothpick provided in this embodiment has a first blade 2 that is a concave curved surface. The first blade 2 is shaped like a fingernail, and the first curved segment 21 is shaped like the leading edge of a fingernail. When cleaning a tooth surface, the curved third and fourth curved segments 23 and 24 deform to fit snugly against the tooth surface. The curved surface has a certain degree of rigidity along the axis. During use, the first curved segment 21 scrapes back and forth across the tooth surface to remove debris.

[0026] When cleaning the gingival sulcus, the first arc segment 21 extends into the gingival sulcus, applying pressure between the gums and the tooth surface toward the tooth surface while scraping toward the tooth tip to remove debris within the gingival sulcus. The curved ends of the third and fourth arc segments 23 and 24 facilitate entry into the gingival sulcus, providing a more effective and thorough cleaning than water rinsing. The first blade 2 is made of thin, curved plastic. Excessive force can cause the plastic to bend, preventing damage to the gums.

[0027] Preferably, the U-shaped support frame 4 is connected to the toothpick rod 1, and the U-shaped support frame 4 is wrapped around the outside of the second arc segment 22, the third arc segment 23 and the fourth arc segment 24. The U-shaped support frame 4 protects and supports the first toothpick 2.

[0028] Example 2:

[0029] like Figure 2 As shown, based on the first embodiment, a handle 5 is provided at the tail end of the toothpick rod 1, and the handle 5 is bent toward the concave surface of the first toothpick piece 2. The handle 5 is convenient for inserting into the oral cavity to clean the inner tooth surface and gingival sulcus.

[0030] Example 3:

[0031] like Figure 3 As shown, on the basis of embodiment 1, it also includes a second signature 3, the second signature 3 is connected to the toothpick rod 1, the first signature 2 and the second signature 3 are spaced apart, the second signature 3 is a concave arc-shaped plane, the front end of the second signature 3 is provided with a tip 35, the tip 35 extends to both sides with a first line segment 31 and a second line segment 32 respectively, the first line segment 31 extends toward the direction of the toothpick rod 1 with a third line segment 33, and the second line segment 32 extends toward the direction of the toothpick rod 1 with a fourth line segment 34.

[0032] The toothpick holder 1 is provided with a first pick 2 and a second pick 3, forming a double-ended toothpick. A distance is maintained between the first and second picks 2 and 3. The second pick 3 is shaped like a diamond leaf. When cleaning the outer interdental spaces, the tip 35 is aligned with the triangular space between the teeth and the gums, with the back of the second pick 3 facing the gums to protect them. Applying pressure pushes the second pick 3 into the interdental space, causing the toothpick to deform, curl, and bend, inserting into the interdental space. The edges of the first and second segments 31 and 32 scrape the outer surfaces of the interdental spaces, cleaning debris.

[0033] When cleaning the inner gaps between teeth, when the second toothpick 3 that has been inserted into the tooth gap is pulled out of the tooth gap, the toothpick deforms again and bends. The edges of the third line segment 33 and the fourth line segment 34 scrape the inner surface of the tooth gap, clean the attachments, and bring out the food residues in the tooth gap.

[0034] The line segment shapes of the first line segment 31, the second line segment 32, the third line segment 33 and the fourth line segment 34 can be as follows:

[0035] The first line segment 31, the second line segment 32, the third line segment 33 and the fourth line segment 34 are all straight line segments;

[0036] The first line segment 31, the second line segment 32, the third line segment 33 and the fourth line segment 34 are all concave arc line segments;

[0037] The first line segment 31, the second line segment 32, the third line segment 33 and the fourth line segment 34 are all convex arc line segments;

[0038] The first line segment 31 and the second line segment 32 are convex arc line segments, and the third line segment 33 and the fourth line segment 34 are concave arc line segments;

[0039] The first line segment 31 and the second line segment 32 are concave arc line segments, and the third line segment 33 and the fourth line segment 34 are convex arc line segments.

[0040] After curling in the above-mentioned situations, the side wings form different three-dimensional curvatures. When the toothpick is inserted into the triangular area between the teeth, the greater the contact area between the side wing edge and the tooth surface, the better the cleaning effect. Since the root of the tooth is arc-shaped, when all four sides are concave, the contact area is the largest. When the four sides are slightly concave, the edge contacts the teeth in the largest area.

[0041] The leaf-shaped wings of the second signature piece 3 utilize the principle of deformable curved surface. When the leaf-shaped wings are inserted into the tooth gap, the wings on both sides curl and deform, and at the same time scrape the side walls of the tooth gap. When the leaf-shaped wings are pulled out of the tooth gap, they curl and deform again, scraping the inner tooth gap, thereby achieving comprehensive cleaning of the tooth gap.

[0042] Example 4:

[0043] like Figure 1 and Figure 4 As shown, based on the third embodiment, the toothpick rod 1 includes a first toothpick rod 11 and a second toothpick rod 12, the first toothpick piece 2 is arranged at one end of the first toothpick rod 11, the second toothpick piece 3 is arranged at one end of the second toothpick rod 12, and the other end of the first toothpick rod 11 is detachably connected to the other end of the second toothpick rod 12.

[0044] The toothpick rod 1 can be separated from the middle to form the first toothpick rod 11 and the second toothpick rod 12, so that the first toothpick piece 2 and the second toothpick piece 3 are separated to form two independent toothpicks, which is convenient for use.

[0045] The present invention utilizes the principles of surface mechanics to design and manufacture. The curved surface can deform in the bending direction, allowing the toothpick to bend and deform to fit between teeth, and its curvature can be changed to fit the tooth surface. Along the axis (perpendicular to the bending direction), the curved surface has a certain degree of rigidity, generating a certain amount of support for scraping the tooth surface and between teeth. It can clean the inner and outer tooth surfaces, the gingival sulcus, and attachments in the teeth, providing a wider cleaning range than traditional toothpicks and dental floss, eliminating blind spots. The scraping cleaning method provides greater cleaning power than water-flushing with an oral irrigator, resulting in more thorough and efficient cleaning. It is compact, convenient, disposable, and inexpensive, making it portable and suitable for use after every meal, even in areas without access to water.

[0046] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
