牙刷是人们常用的牙齿清洁用具，常用的牙刷主要分为普通的手动牙刷和电动牙刷两大类。现有的手动牙刷的结构是在手柄的一头植上刷毛。使用时，通过刷毛与牙齿的磨擦，把牙齿上的食物残渣刷掉。在这个过程中，为了刷毛能与牙齿磨擦，使用者需要通过不断地对牙刷施加上下或前后的往复直线运动。但是，由于刷毛具有柔软性，它使刷毛与牙齿的磨擦滞后于手柄的直线运动，同时刷毛的柔软性，还使刷毛与牙齿的磨擦幅度远小于手柄的运动幅度。由于这些原因再加上牙刷在清洁位于口腔最里头的臼齿和智慧齿时运动幅度受口腔的限制，这样就产生了一个很严重的问题。这个问题就是位于口腔最里头的臼齿和智慧齿得不到与其他牙齿同样的清洁擦拭。使这些牙齿特别容易坏掉，这也是牙医主张打掉智慧齿的原因之一。Toothbrush is people's commonly used tooth cleaning tool, and toothbrush commonly used is mainly divided into two big classes of common manual toothbrush and electric toothbrush. The structure of existing manual toothbrush is to plant bristle on one end of handle. During use, the food residue on the teeth is brushed off through the friction between the bristles and the teeth. During this process, in order for the bristles to rub against the teeth, the user needs to continuously apply up-and-down or back-and-forth linear motions to the toothbrush. But, because the bristles have softness, it makes the friction between the bristles and the teeth lag behind the linear motion of the handle, and the softness of the bristles also makes the friction range between the bristles and the teeth much smaller than the motion range of the handle. For these reasons, combined with the limitation of the toothbrush's range of motion when cleaning the innermost molars and wisdom teeth, a serious problem arises. The problem is that the molars and wisdom teeth, which are located in the innermost part of the mouth, do not get the same cleaning and wiping as the other teeth. This makes these teeth particularly vulnerable to failure, which is one of the reasons why dentists advocate removing wisdom teeth.

现有技术下一般的手动牙刷和电动牙刷除有着上述的缺点外，还有一个有一个不足的地方，就是它在使用时，一次只能清洁牙齿的一个面。这样就使牙齿的清洁用时不能节约，不符合现代人紧张的生活节奏。General manual toothbrush and electric toothbrush under the prior art except having above-mentioned shortcoming, also have a place that has a deficiency, be exactly that it can only clean a face of tooth once when it is in use. Like this just makes the cleaning time of tooth can not save, does not meet the tense rhythm of life of the modern.

发明内容Contents of the invention

为了让牙刷更好地清结牙齿，本发明采取了如下技术措施：刷头4装在手柄2上，手柄2呈Y字形结构，刷头4由两个圆盘和一个圆柱组成工字形骨架并在工字形骨架的内表面植上刷毛构成，电机1装在手柄2上，电机1的转轴3上装有蜗杆5，刷头4的转轴上装有蜗轮6，蜗杆5与蜗轮6齿合在一起，电机1可通过蜗杆5和蜗轮6驱动刷头4转动（如图1所示）；或刷头4装在手柄2上，手柄2呈Y字形结构，刷头4由两个圆盘和一个圆柱组成工字形骨架并在工字形骨架的内表面植上刷毛构成，电机1装在手柄2上，电机1的转轴3上装有小伞齿7，刷头4的转轴上装有大伞齿8，大伞齿8与小伞齿7齿合在一起，电机1可通小伞齿7和大伞齿8驱动刷头4转动（如图2所示）。In order to allow the toothbrush to clean teeth better, the present invention adopts the following technical measures: the brush head 4 is mounted on the handle 2, the handle 2 is in a Y-shaped structure, the brush head 4 is composed of two discs and a cylinder to form an I-shaped skeleton and The inner surface of the I-shaped frame is formed by planting bristles, the motor 1 is installed on the handle 2, the worm 5 is installed on the rotating shaft 3 of the motor 1, and the worm wheel 6 is installed on the rotating shaft of the brush head 4, and the worm 5 and the worm wheel 6 teeth are combined together. The motor 1 can drive the brush head 4 to rotate through the worm 5 and the worm gear 6 (as shown in Figure 1); or the brush head 4 is installed on the handle 2, the handle 2 is in a Y-shaped structure, and the brush head 4 is composed of two discs and a cylinder Form an I-shaped skeleton and plant bristles on the inner surface of the I-shaped skeleton. The motor 1 is mounted on the handle 2. The rotating shaft 3 of the motor 1 is equipped with a small bevel tooth 7. The rotating shaft of the brush head 4 is equipped with a large bevel tooth 8. The bevel teeth 8 and the small bevel teeth 7 are combined together, and the motor 1 can drive the brush head 4 to rotate through the small bevel teeth 7 and the large bevel teeth 8 (as shown in Figure 2).

这样做的好处是：由于本电动牙刷的最前端就是刷毛，而且它的刷头可无限量的旋转而不是现有手动牙刷和电动牙刷的小幅摆动。因此，它能有效地克服刷毛柔软所带来的运动滞后和幅度减小等问题，使它的清洁盲区大大小于现有技术下的各种牙刷、使口腔最里面的臼齿和智慧齿的清洁能得到有效的改善。同时由于本发明的刷头是旋转的，它的刷毛既有垂直方向的运动也有前后方向的运动，这样有利于它能同时对牙缝的擦拭清洁。另一方面，本发明的刷头4呈工字形，且内表面植有用于清洁牙齿的刷毛。因此，当它在上下颚之间的牙齿中旋转时，能同时清洁上下颚牙齿一共六个齿面，即它可清洁上颚牙齿的三个面（左右和下齿面）和下颚牙齿的三个面（左右和上齿面）使刷牙用时大大缩短。The advantage of doing like this is: because the front end of this electric toothbrush is exactly bristle, and its brush head can be rotated indefinitely instead of the slight swing of existing manual toothbrush and electric toothbrush. Therefore, it can effectively overcome the problems of movement hysteresis and amplitude reduction caused by soft bristles, making its cleaning blind area much smaller than that of various toothbrushes in the prior art, and making the cleaning performance of the innermost molars and wisdom teeth in the oral cavity be effectively improved. Simultaneously, because the brush head of the present invention is rotating, its bristles have the movement of both vertical direction and forward and backward direction, which is beneficial for it to wipe and clean between teeth simultaneously. On the other hand, the brush head 4 of the present invention is H-shaped, and the inner surface is planted with bristles for cleaning teeth. Therefore, when it rotates in the teeth between the upper and lower jaws, it can clean a total of six tooth surfaces of the upper and lower teeth at the same time, that is, it can clean the three sides of the upper teeth (left and right and lower teeth) and the three sides of the lower teeth. The surface (left, right and upper tooth surface) greatly shortens the time for brushing teeth.

具体实施方式 Detailed ways

为了让牙刷更好地清结牙齿，特别是位于口腔最里面的臼齿和智慧齿，同时也为了减小使用者刷牙用时。本发明采取了如下技术方案：把刷头4装在呈Y字形结构的手柄2上。刷头4由两个圆盘和一个圆柱组成工字形骨架并在工字形骨架的内表面植上刷毛构成。这样就构成一个具有三个工作面（一个圆柱面，两个圆形盘面）的刷头。当它旋转时可同时擦拭上下六共个齿面；为了驱动刷头4转动，本发明把电机1装在手柄2上，电机1的转轴3装上蜗杆5，刷头4的转轴装上蜗轮6（如图1所示）。蜗杆5与蜗轮6齿合在一起。这样电机1就可以通过蜗杆5蜗轮6驱动刷头4转动清洁牙齿；另一实施方式是在上面的部份基础上，把电机1转轴3上的蜗杆5改装小伞齿7、刷头4的转轴上改装大伞齿8。大伞齿8与小伞齿7齿合在一起。电机1就可以通过大小伞齿驱动刷头4转动清洁牙齿（如图2所示）。由于刷头4具有上下对称的上三个和下三个一共六个的可工作面，因此它转动时就能同时清洁六个牙齿面，令使用者刷牙用时大大缩短。In order to allow the toothbrush to better clean the teeth, especially the molars and wisdom teeth located in the innermost part of the oral cavity, and also to reduce the time for users to brush their teeth. The present invention adopts the following technical scheme: the brush head 4 is mounted on the handle 2 in a Y-shaped structure. The brush head 4 is composed of two discs and a cylinder to form an I-shaped skeleton and to plant bristles on the inner surface of the I-shaped skeleton. In this way, a brush head with three working surfaces (a cylindrical surface and two circular disc surfaces) is formed. When it rotates, it can wipe up and down six total tooth surfaces at the same time; in order to drive the brush head 4 to rotate, the present invention installs the motor 1 on the handle 2, the rotating shaft 3 of the motor 1 is equipped with a worm screw 5, and the rotating shaft of the brush head 4 is equipped with a worm gear 6 (as shown in Figure 1). Worm screw 5 and worm wheel 6 teeth are engaged together. Motor 1 just can drive brush head 4 to rotate and clean teeth through worm screw 5 and worm gear 6 like this; Refit big bevel tooth 8 on the rotating shaft. The large bevel tooth 8 is combined with the small bevel tooth 7 teeth. The motor 1 can drive the brush head 4 to rotate and clean the teeth through the large and small bevel teeth (as shown in Figure 2). Because the brush head 4 has a total of six workable surfaces, the upper three and the lower three, which are up and down symmetrical, it can clean six tooth surfaces at the same time when it rotates, so that the user's teeth brushing time is greatly shortened.
