As shown in FIG. 1 , in the first embodiment of the present invention, the toothbrush 1 can be convenient for the user to brush their teeth and penetrate deep into the teeth for cleaning. The toothbrush 1 includes a handle 10 , a brush head 20 and a plurality of bristles 30 . The handle 10 can be held by the user. The brush head 20 includes a brush head front end 21 and a brush head tail end 22 . The brush head tail end 22 is combined with the handle 10 , and a plurality of bristles 30 are combined with the brush head 20 . A plurality of bristles 30 are used to clean the teeth.

As shown in FIGS. 1 and 2 , the improvement of the toothbrush 1 of the present invention focuses on the fact that the plurality of bristles 30 include a plurality of interdental bristles 31 and a plurality of main bristles 32 , and the plurality of interdental bristles 31 are concentrated on the front end 21 of the brush head Whereas, a plurality of main bristles 32 are arranged on other positions of the brush head 20 . It should be noted that, in the accompanying drawings of the present utility model, although the interdental bristles 31 and the main bristles 32 are drawn as thicker black lines, each of the black lines is composed of thinner bristle bundles, so each Black lines should be considered multiple bristles, not one bristles.

In the first embodiment of the present invention, the plurality of main bristles 32 are like the bristles of a conventional toothbrush, and the main purpose is to brush teeth. The lengths of the plurality of interdental bristles 31 are longer than the plurality of main bristles 32, and the number of the plurality of interdental bristles 31 is much smaller than that of the plurality of main bristles 32. The main purpose of the plurality of interdental bristles 31 is to brush teeth The gap between the teeth to remove the food residue between the teeth, as shown in the schematic diagram in Figure 3.

As shown in FIG. 2 and FIG. 4 , in the first embodiment of the present invention, in order to allow the plurality of interdental bristles 31 to easily extend into the interdental space for cleaning, and even to brush out the food residue stuck in the interdental space, The inventors have designed a range limit for the size and number of the plurality of bristles 30 . The average interdental bristle length of the plurality of interdental bristles 31 is L1, and the average main bristle length of the plurality of main bristles 32 is L2, wherein the relationship between the average interdental bristle length and the average main bristle length is 10%≤(L1- L2)/L1≤50%; a better relationship between the average interdental bristle length and the average main bristle length is 20%≤(L1-L2)/L1≤40%.

In the first embodiment of the present invention, the longest interdental bristle length of the plurality of interdental bristles 31 is LM1, the longest main bristle length of the plurality of main bristles 32 is LM2; the longest interdental bristles 31 are The interdental bristle length LM1 is longer than the longest main bristle length LM2 of the plurality of main bristles 32, and the relationship between the longest interdental bristle length LM1 and the longest main bristle length LM2 is 10%≤(LM1-LM2) /LM1≤40%.

Through the above-mentioned length design, when the user is brushing teeth, and the plurality of main bristles 32 are in contact with the tooth surface and cannot penetrate into the interdental space, the plurality of interdental bristles 31 with longer lengths can still easily extend into the interdental space to prevent to clean. However, the range design of the average interdental bristle length L1, the average main bristle length L2, the longest interdental bristle length LM1 and the longest main bristle length LM2 is not limited to the above, and can be changed according to the needs of use, for example, children's The teeth are small and the interdental depth is shallow, so the relationship between the average interdental bristle length L1 and the average main bristle length L2, and the relationship between the longest interdental bristle length LM1 and the longest main bristle length LM2, can be According to the child's teeth, the changes are 20%≤(L1-L2)/L1≤30%, 10%≤(LM1-LM2)/LM1≤30%.

In the first embodiment of the present invention, the number of the plurality of interdental bristles 31 should not be too large, because the interdental bristles 31 are specially designed to brush between the teeth, so if the number of the plurality of interdental bristles 31 is too large, it is difficult to stretch into the narrow gap between the teeth. If the number of interdental bristles of the plurality of interdental bristles 31 is N1, and the number of main bristles of the plurality of main bristles 32 is N2, it is recommended that the relationship between the number of interdental bristles N1 and the number of main bristles N2 be 1%≤N1/N2 ≤15%. In addition, because the interdental space is narrow, the extension length of the interdental bristles 31 should not be too long; therefore, the extension length of the plurality of interdental bristles 31 along a longitudinal axis 25 of the brush head 20 is W, and the range of the extension length W is 0.06cm≤ W≤0.4cm, the optimum range of the extension length W is 0.08cm≤W≤0.3cm.

However, the range design of the number of interdental bristles N1, the number of main bristles N2 and the extension length W is not limited to the above, and can be changed according to the needs of use. The relationship between the number of bristles N1 and the number of main bristles N2 is 1%≤N1/N2≤5%, so as to reduce the number N1 of interdental bristles in accordance with children's teeth.

In order to penetrate between the teeth for cleaning, a plurality of interdental bristles 31 can also be arranged at other positions, such as at the end 22 of the brush head, please refer to FIG. An enlarged view of the bristles. in this utility model. The difference between the second embodiment and the first embodiment is that the positions of the plurality of interdental bristles 31 are different, and the rest of the length and quantity of the bristles are the same as those described in the first embodiment, so they are not repeated here.
