Abstract
Description
本发明属于口腔健康与卫生技术领域，具体涉及一种三刷联转式牙刷头.The invention belongs to the technical field of oral health and hygiene, and in particular relates to a three-brush interlocking toothbrush head.
现有的刷头多为平头刷型牙刷头，无论是手动还是电动旋转牙刷，刷毛顶端在牙齿表面做来回折返运动或圆周运动。这样带来的问题是容易损伤牙龈，并进入牙龈覆盖区造成牙龈伤害并萎缩。在长期以折返运动刷牙导致损伤牙龈和牙齿的结合部，在结合部形成刷伤沟。而且在刷牙时，平头刷型牙刷头不易伸入相邻牙齿之间的凹面，导致刷不干净，残留物长期累积形成结石造成口臭和牙周疾病。而且多数人们在刷牙过程中用力较大，导致短时间内就使得刷毛倾倒，倒毛后刷头对牙龈结合部的伤害更加严重，并且清洁牙齿功能也随之下降，不得不提前更换。人们在刷牙过程中不能很好的控制力度，导致刷毛对牙龈和牙齿的压力和方向不稳定，时常发生搓伤牙龈和空腔内壁的情况，尤其是儿童未掌握正确的刷牙方法，一旦对口腔造成损伤就会对刷牙产生抵触。而且现有的牙刷只有一个刷头，一次接触只能刷牙齿的一个面，需要调整刷头的方向才能完成牙齿内外侧面及牙冠的清理，使得刷牙时间长，无法满足人们日益加快的生活节奏。Most of the existing brush heads are flat-brush type toothbrush heads. No matter it is a manual or electric rotating toothbrush, the top of the bristles performs a back-and-forth reciprocating motion or a circular motion on the tooth surface. The problem with this is that it is easy to damage the gums and enter the gum coverage area to cause gum damage and recession. Brushing with a reentry motion for a long time results in damage to the junction of the gums and the teeth, and a brushing groove is formed in the junction. Moreover, when brushing teeth, the flat-brush type toothbrush head is not easy to protrude into the concave surface between adjacent teeth, resulting in unclean brushing, and the long-term accumulation of residues forms calculus, causing bad breath and periodontal disease. Moreover, most people use a lot of force in the process of brushing their teeth, which leads to the tipping of the bristles in a short period of time. After the bristles are poured, the damage of the brush head to the gingival joint is more serious, and the cleaning function of the teeth is also reduced, so it has to be replaced in advance. People can't control the force well during the brushing process, resulting in unstable pressure and direction of the bristles on the gums and teeth, often rubbing the gums and the inner wall of the cavity, especially if children do not master the correct brushing method, once the oral cavity is rubbed. Injury can result in resistance to brushing. Moreover, the existing toothbrush has only one brush head, and only one side of the tooth can be brushed at a time. The direction of the brush head needs to be adjusted to complete the cleaning of the inner and outer sides of the teeth and the crown, which makes the brushing time long and cannot meet people's increasingly accelerated life rhythm. .
发明内容SUMMARY OF THE INVENTION
为克服上述技术问题，本发明提供了一种一次动作即可清理牙齿内外侧面及牙冠的三刷联转式牙刷头。In order to overcome the above-mentioned technical problems, the present invention provides a three-brush interlocking toothbrush head which can clean the inner and outer surfaces of teeth and crowns in one action.
为达到上述目的，本发明是通过以下的技术方案来实现的。In order to achieve the above object, the present invention is achieved through the following technical solutions.
一种三刷联转式牙刷头，包括刷头、防护罩和传动装置；所述刷头为柱形，刷头柱面设有刷毛，刷头两端设有转轴；所述刷头有三个，分别为顶刷、左侧刷、右侧刷，各刷头轴线相互平行，三个刷头呈品字型排布；所述防护罩为U型曲面，防护罩两端设有三对轴套分别对应三个刷头的转轴；防护罩的开口处设置左侧刷、右侧刷，防护罩的底部设置顶刷；所述顶刷底部转轴端部设有连接头，在三个刷头之间设有传动装置。三个刷头呈品字型排布，由左侧刷和右侧刷负责清理牙齿的内外侧面，由顶刷负责清理牙冠，三个刷头的间距与正常牙齿的大小相匹配，无需再额外施加压力即可对牙齿完成清洁，避免用力过大导致牙龈或空腔受伤，刷毛也不易倒毛，同时清洁牙齿的三个面，各刷毛接触牙齿的力度稳定接触，使用舒适，清洁效率高。由防护罩遮挡刷毛防止刷毛对口腔内壁的摩擦。由 于刷毛端部在牙齿侧面做切线运动，顺着牙龈生长方向旋转，不损伤牙龈、不进入牙龈覆盖区，牙龈和牙齿的结合部受力均匀不会形成刷伤沟，能够顺利的进入相邻牙齿间的凹面，清洁时覆盖范围全面。A three-brush interlocking toothbrush head includes a brush head, a protective cover and a transmission device; the brush head is cylindrical, the cylindrical surface of the brush head is provided with bristles, and the two ends of the brush head are provided with rotating shafts; the brush head has three , are the top brush, the left brush and the right brush, the axes of the brush heads are parallel to each other, and the three brush heads are arranged in a zigzag shape; the protective cover is a U-shaped curved surface, and there are three pairs of bushings at both ends of the protective cover Corresponding to the rotating shafts of the three brush heads respectively; a left brush and a right brush are arranged at the opening of the protective cover, and a top brush is arranged at the bottom of the protective cover; There is a transmission in between. The three brush heads are arranged in a zigzag pattern. The left and right brushes are responsible for cleaning the inner and outer sides of the teeth, and the top brush is responsible for cleaning the crowns.

Exposing the bristles of the top brush outside the protective cover can be used to gently scrape the surface of the tongue for oral health care.
进一步地所述刷毛在刷头柱面交替排布。刷毛会在旋转的过程中自动适应牙龈和牙齿的高度变化，清洁时覆盖范围全面,不易残留食物残渣，避免结实的形成。Further, the bristles are alternately arranged on the cylindrical surface of the brush head. The bristles will automatically adapt to the height changes of the gums and teeth during the rotation, and the coverage will be comprehensive when cleaning, and it will not be easy to leave food residues and avoid the formation of firmness.
进一步地所述传动装置为齿轮组或柔性传动条或刚性传动轴。三个刷头以顶刷为主动刷头与刷柄的驱动端连接，在顶刷的转轴处设有齿轮或皮带轮，通过齿轮组或皮带或带有冠齿的刚性传动轴驱动左侧刷和右侧刷同步旋转。Further, the transmission device is a gear set or a flexible transmission bar or a rigid transmission shaft. The three brush heads take the top brush as the active brush head and are connected with the driving end of the brush handle. There are gears or pulleys at the rotating shaft of the top brush, and the left brush and the The right brush rotates synchronously.
进一步地所述左侧刷、右侧刷转动方向相反，且由防护罩开口处向防护罩中心转动。符合牙齿部位的人体工学，沿牙齿生长方向旋转，不损伤牙龈并能将食物残渣向齿尖清理。Further, the left brush and the right brush rotate in opposite directions, and rotate from the opening of the protective cover to the center of the protective cover. It conforms to the ergonomics of the teeth, rotates along the direction of tooth growth, does not damage the gums and can clean food residues to the tips of the teeth.
