[0026] The following further describes the present utility model in detail with specific embodiments with reference to the accompanying drawings.
[0027] Embodiment 1
[0028] As Figures 1-6As shown, the interdental brush includes a handle 10, a brush head 20, and toothpicks 30. The brush head 20 and the toothpicks 30 are respectively connected to the handle 10, and the toothpicks 30 are located at the tail of the entire interdental brush. The handle 10 is straight as a whole (not in a curved shape). The handle 10 has a middle part, a front end 11, and a rear end 12. The brush head 20 is connected to the front end 11, and the toothpicks 30 are connected to the rear end 12. The top surface of the middle part of the handle 10 is a plane, and the bottom surface of the middle part of the handle 10 is a plane. These two planes are parallel to each other. The top surface of the middle part of the handle 10 is provided with a plurality of oval anti-slip grooves 13 (showing 7 oval anti-slip grooves 13 in the figure is only an example). The plurality of oval anti-slip grooves 13 are arranged in a line. Similarly, the bottom surface of the middle part of the handle 10 is also provided with a plurality of oval anti-slip grooves 13 (for example, there can be 7 oval anti-slip grooves arranged in a line). The front end 11 of the handle 10 also has a top surface and a bottom surface that are parallel to each other. The top surface of the front end 11 is provided with an oval anti-slip groove 14, and the bottom surface of the front end 11 is provided with an oval anti-slip groove. The rear end 12 also has a top surface and a bottom surface that are parallel to each other. The top surface of the rear end 12 is provided with an oval anti-slip groove 15, and the bottom surface of the rear end 12 is provided with an oval anti-slip groove 15. Refer to Figure 2 , 3 , 5, the middle part of the handle 10 is rectangular (not cylindrical as commonly seen in the prior art), that is, the width of the middle part of the handle 10 is greater than the thickness. Preferably, the ratio of the width dimension to the thickness dimension is 2:1. From Figure 5 , it can be seen that the four corners of the middle part of the handle 10 are rounded corners 10-1. Refer to Figure 2 , 3 , 5, the front end 11 is also rectangular, that is, the width of the front end 11 is greater than the thickness. The four corners of the front end 11 are also rounded corners. In addition, the width of the front end 11 is less than the width of the middle part of the handle 10, and the thickness of the front end 11 is greater than the thickness of the middle part of the handle 10. Refer to Figure 6 , at the connection between the top surface of the middle part of the handle 10 and the top surface of the front end 11 is an arc-shaped slope transition part 10-2, and at the connection between the bottom surface of the middle part of the handle 10 and the bottom surface of the front end 11 is an arc-shaped slope transition part 10-3. Similarly, the rear end 12 is also rectangular (the width of the rear end 12 is greater than the thickness of the rear end 12). The four corners of the rear end 12 are also rounded corners. The width of the rear end 12 is less than the width of the middle part of the handle 10, and the thickness of the rear end 12 is greater than the thickness of the middle part of the handle 10. At the connection between the top surface of the middle part of the handle 10 and the top surface of the rear end 12 is an arc-shaped slope transition part, and at the connection between the bottom surface of the middle part of the handle 10 and the bottom surface of the rear end 12 is an arc-shaped slope transition part.
[0029] The structure of the toothpicks 30 can adopt the structure in the prior art. For example, the toothpick structure in the utility model patent with the authorization announcement number CN217185178U can be adopted. The toothpicks 30 are used to achieve the function of toothpicks and can remove food residues between teeth.
[0030] The structure of the brush head 20 can adopt the conventional brush head structure in the prior art. The brush head 20 is usually provided with a support rod and a rubber sleeve. The rubber sleeve is connected to the support rod, and there are many bristles on the rubber sleeve. The material of the rubber sleeve is usually TPE material or silica gel material (so the material of the bristles is TPE material or silica gel material). Therefore, the brush head 20 is relatively soft. For example, the silica gel brush 30 in the utility model patent with the authorization announcement number CN209864125U, and for another example, the rubber sleeve 3 and the bristles 4 in the utility model patent with the authorization announcement number CN217185178U.
[0031] The present utility model makes technical improvements to the brush head structure, referring to Figure 1 , 2 , 3, 5 and 7, the brush head 20 includes a soft rod 21 and a plurality of conical thorns 22 connected to the soft rod 21. The specific improvement is carried out on the conical thorns 22, that is: the shape of each conical thorn 22 is conical, and the plurality of conical thorns 22 are spirally distributed along the circumference of the soft rod 21; along the length direction of the soft rod 21, all the conical thorns 22 are divided into 6 columns, and the multiple conical thorns in each column are linearly distributed, and the lengths of the multiple conical thorns in each column gradually decrease (the conical thorn at the root of the soft rod 21 is the longest, and the conical thorn at the end of the soft rod 21 is the shortest).
[0032] When using the above interdental brush, the user pinches the handle 10 with fingers and inserts the brush head 20 between two teeth to move, so as to remove food residues and debris between the teeth. Since the overall end size of the brush head 20 is the smallest and the length of the tapered spines 22 is smaller the closer to the end, it is very easy to insert into the gap between the teeth, and the pulling activity is easier, which can better remove food residues and debris between the teeth. All the tapered spines are spirally distributed, which can better remove food residues and debris between the teeth, thus improving the cleaning effect and efficiency; it is also applicable to gaps with different sizes between teeth, whether large or small. When necessary, a toothpick 30 can be used to pick out or loosen the food residues between the teeth. Loosening the food residues with the toothpick 30 is beneficial for the brush head 20 to remove the food residues. Regarding the structure of the handle 10, the user pinches the middle part of the handle 10 with fingers, that is, pinches the top surface and the bottom surface of the middle part of the handle 10, so that it can be held more firmly and stably, and the holding effect is better than that of the cylindrical handle in the prior art; the elliptical anti-slip grooves provided on the handle 10 can further play an anti-slip effect, further realizing a more firm and stable grip, and can also improve the comfort of pinching the handle with fingers. The arc-shaped slope transition parts provided at both ends of the handle 10 near the front end 11 and the rear end 12 can make the user's fingers feel this arc-shaped slope transition part when pinching, so as to help remind the operator to pinch the middle part of the handle 10 with fingers, preventing the fingers from pinching the front end 11 or the rear end 12, that is, restricting the fingers to the middle part of the handle 10; in addition, when the operator needs to apply a greater force to move the brush head 20, the arc-shaped slope transition part can be used as the force-bearing surface of the fingers, facilitating the generation of the required greater force.
[0033] Embodiment 2
[0034] As Figures 8-12 shown, the interdental brush includes a handle 40 and a brush head 50, and the brush head 50 is connected to the handle 40. The handle 40 is straight as a whole, the cross-section of the handle 40 is elliptical, and a plurality of elliptical anti-slip grooves 42 arranged in a line are provided on the top surface of the handle 40, and a plurality of elliptical anti-slip grooves arranged in a line are also provided on the bottom surface of the handle 40. The handle 40 is provided with a toothpick part 41, the toothpick part 41 is provided with a hook 41-1, and a plurality of cross-shaped protrusions 41-2 are provided on the top surface of the toothpick part 41 (the function of the cross-shaped protrusions 41-2 is to increase friction and scrape off and take out the residues on the teeth), and a plurality of cross-shaped protrusions are also provided on the bottom surface of the toothpick part 41. The brush head 50 includes a soft rod 51 and a plurality of tapered spines 52 connected to the soft rod 51. The shape of each tapered spine 52 is conical, and the plurality of tapered spines 52 are spirally distributed along the circumference of the soft rod 51; along the length direction of the soft rod 51, all the tapered spines 52 are divided into 6 columns, and the plurality of tapered spines in each column are linearly distributed, and the lengths of the plurality of tapered spines in each column gradually decrease (the tapered spine at the root of the soft rod 51 is the longest, and the tapered spine at the end of the soft rod 51 is the shortest).
[0035] When using this interdental brush, the user pinches the handle 40 with fingers and inserts the brush head 50 between two teeth for movement, so as to remove the food residues and debris between the teeth. Since the overall end size of the brush head 500 is the smallest and the length of the tapered spines 52 is smaller closer to the end, it is easy to insert into the gap between the teeth, and the pulling movement is also easier, which can better remove the food residues and debris between the teeth. The spiral distribution of all the tapered spines can better remove the food residues and debris between the teeth, thus improving the cleaning effect and efficiency; it is also applicable to gaps with different sizes between teeth, whether large or small. When necessary, the hook 41-1 of the toothpick part 41 can be used to pick out or loosen the food residues between the teeth. Loosening the food residues with the toothpick part 41 is beneficial for the brush head 50 to remove the food residues. The structure of the handle 40 has a good anti-slip effect when the operator pinches it.
[0036] The above has schematically described the present utility model and its implementation manners. This description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present utility model. The actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by it and, without departing from the gist of the creation of the present utility model, adopt other forms of part configurations, driving devices and connection manners to design structures and embodiments similar to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
