Abstract
Description
Technical Field
[0001] This utility model relates to the field of daily necessities technology, and more specifically, to a double-headed toothbrush. Background Technology
[0002] As people pay increasing attention to oral hygiene, brushing their teeth is becoming more and more important. However, depending on the level of oral hygiene needed, people usually use different brush heads with different bristles to clean their mouths. For example, before going to bed at night, it's necessary to thoroughly remove food debris and plaque accumulated throughout the day to prevent cavities and periodontal disease, so a stiffer bristle brush is used for deep cleaning. In the morning, it's more important to remove bad breath accumulated overnight and avoid irritating the gums, so a softer bristle brush is used for gentle cleaning. Currently, most toothbrushes on the market only come with one brush head, so using both soft and stiff brush heads usually requires having two toothbrushes, which is extremely inconvenient.
[0003] Although double-headed toothbrushes have appeared on the market, such as the double-headed toothbrush with patent publication number CN202698184U, which has two brush heads fixed at both ends of the toothbrush handle, this problem can be solved by setting different brush head types. However, fixing two brush heads to both ends of the toothbrush will expose both brush heads. During use, not only is it easy for the other brush head to come into contact with the arm and cause discomfort, but it also presents problems such as inconvenience in placement and difficulty in ensuring the hygiene of the brush heads.
[0004] The aforementioned shortcomings deserve improvement. Summary of the Invention

[0031] See Figures 1 to 4 As shown, this embodiment of the utility model provides a double-headed toothbrush, including a toothbrush handle 10, with a first brush head 11 and a second brush head 12 mounted on the same side at both ends of the handle 10. Preferably, both the first brush head 11 and the second brush head 12 are provided with nylon bristles 14, and one of the first brush head and the second brush head has hard nylon bristles 14, while the other has soft nylon bristles 14. By setting two types of nylon bristles 14 with different hardness, the user's needs for oral hygiene cleaning with bristles of different hardness during the morning and evening can be fully met.
[0032] Furthermore, the toothbrush handle 10 of this utility model is equipped with a rotating shaft 13, which is located between the first brush head 11 and the second brush head 12. The toothbrush handle 20 is provided with a support hole 23. By installing the rotating shaft 13 on the support hole 23, the toothbrush handle 10 can be fixed on the toothbrush handle 20 and can rotate around the support hole 23.
[0033] Specifically, the pivot 13 on the toothbrush handle 10 has a cut surface 15, and the support hole 23 at the top of the toothbrush handle 20 has an opening 25. The cut surface 15 matches the opening 25, allowing the pivot 13 to be installed and removed from the support hole 23 via the opening 25. This enables the replacement of individual components when the toothbrush handle 10 or the toothbrush handle 20 is partially damaged, increasing economic practicality. Preferably, the cut surface 15 is perpendicular to the toothbrush handle 10 to ensure the stability of the connection between the toothbrush handle 10 and the toothbrush handle 20 during use.
[0034] In this invention, the double-headed toothbrush also includes a toothbrush handle 20. The front and rear sides of the toothbrush handle 20 are provided with a first storage cavity 21 that matches the first brush head 11 and a second storage cavity 22 that matches the second brush head 12. The toothbrush handle 10 is rotatably connected to the toothbrush handle 20, so that when the first brush head 11 is stored in the first storage cavity 21, the second brush head 12 extends out, and when the second brush head 12 is stored in the second storage cavity 22, the first brush head 11 extends out, thereby improving the comfort of using the toothbrush and avoiding interference caused by both brush heads being exposed during use.
[0035] In fact, both the first storage cavity 21 and the second storage cavity 22 are equipped with support parts 24. The support parts 24 are used to limit contact with the toothbrush handle 10, which can prevent the brush head from being excessively embedded in the toothbrush handle 20, thereby avoiding damage to the bristles. Furthermore, the bottom of the second storage cavity 22 is also provided with a bottom wall 26, the position of which corresponds to the position of the second brush head 12, so as to ensure that when holding the toothbrush handle 20, the brush head is completely in the storage cavity, avoiding contact between the palm and the bristles, and ensuring a hygienic environment when storing.
[0036] Furthermore, the first length of the distance from the top of the first brush head 11 to the pivot 13 is greater than the second length of the distance from the top of the second brush head 12 to the pivot 13, and the distance from the bottom 21 of the first storage cavity to the support hole 23 is equal to the first length, and the distance from the bottom of the second storage cavity 22 to the support hole 23 is equal to the second length, so that when using the first brush head 11 or the second brush head 12, the other brush head can be fitted and stored in its matching storage cavity. Preferably, the difference between the first length and the second length is not less than the length of the head of the second brush head, so that the brush head located in the storage cavity is not excessively exposed, improving the hygiene environment when storing the toothbrush.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
