Description

说明书
Title of Invention:一种超声波牙刷 技术领域
[1] 本发明涉及一种牙刷， 更具体地说， 涉及一种具有超声波清洗功能的超声波牙 刷。
背景技术
[2] 超声波清洗的原理可以用"空化"现象来解释， 所谓空化即为空穴在液体中形成 及空穴迅速闭合， 当超声波振动在液体中传播的音波压强达到一个大气压吋， 超声波的音波压强峰值就可以达到真空或负压， 但实际上无负压存在， 因此在 液体中产生一个很大的压力， 将液体拉裂成空洞， 该空洞在超声波压强反向达 到最大吋破裂， 由于破裂吋产生的强烈的冲击波， 该冲击波可以将附着在物体 上的污物撞击下来。 只有在某区域的液体压力低于该气泡内气体压力吋才会在 该区域产生空化现象， 故超声波振幅足够大吋才能满足这一条件。 产生空化所 需的最小功率被称为空化临界点。 不同的液体存在不同的空化临界点， 故超声 波能量必须超过该临界点才能达到清洗效果。 也就是说， 只有能量超过临界点 才能产生空化泡， 以便进行超声波清洗。 在水中产生空化现象吋， 超声波的功 率密度要达到 0.3W/cm2以上。
[3] 超声波的频率对超声波的空化作用影响也很大， 超声波频率越低， 在液体中产 生空化越容易， 频率越高， 所需要的声强即功率密度越大， 当超声波频率在 20 〜100kHz范围吋， 空化产生的空穴在消失过程产生的冲击作用十分突出。 当超 声波的频率处在特高频率范围吋， 例如超过 1000kHz吋， 超声波的作用主要是其 本身巨大的能量作用， 并不产生空化现象。
[4] 现有技术的超声波牙刷其电源、 振荡电路和超声波发生器件都设置在牙刷主体 内， 电源一般釆用电池或可充电电池， 超声波发生器一般釆用压电陶瓷片， 这 种结构产生的超声波频率高、 功率密度小， 很难达到空化临界点， 难以实现超 声清洗。 例如一项中国专利申请 （申请号： CN200410021841.7) 公开的超声波 振动牙刷， 所釆用的超声波发生器是超声波瓷片， 振动频率在为 1.6〜2.4MHZ， 产生的超声波的功率密度仅为 10〜100mW/cm2， 根本无法实现空化清洗， 只是 利用超声振动产生的流体振动来清洁牙齿， 清洁功能有限。 又如另一项中国专 利 （专利号： ZL200820023178.8) 公开的超声波牙刷， 其超声波换能片产生 300 kHz~500kHz的超声波， 也同样很难实现超声空化清洗。 上述这类牙刷只能称之 为超声振动牙刷。
发明内容
[5] 本发明要解决的技术问题在于， 针对现有技术的上述超声波牙刷难以实现超声 波清洗的缺陷， 提供一种可以实现超声波清洗功能的超声波牙刷。
[6] 本发明解决其技术问题所釆用的技术方案是： 构造一种超声波牙刷， 包括具有 高频振荡信号输出的电源， 其特征在于， 还包括一体成型的牙刷本体、 密封在 牙刷本体头部的超声波发生装置、 以及由牙刷本体中引出的用于连接所述超声 波发生装置和所述电源的导线。
[7] 在本发明所述的超声波牙刷中， 所述超声波发生装置包括金属壳体、 与金属壳 体配合的上盖、 以及置于壳体内的超声波换能器， 所述超声波换能器粘接固定 在所述金属壳体的内壁， 所述超声波换能器通过所述导线与所述电源电连接。
[8] 在本发明所述的超声波牙刷中， 所述超声波换能器包括依次叠放在一起的下金 属盖板、 两片压电陶瓷片和上金属盖板； 还包括设置在两片压电陶瓷片之间的 正极金属接线片、 设置在上金属盖板和压电陶瓷片之间的负极金属接线片； 还 包括穿过所述上金属盖板、 压电陶瓷片、 正极金属接线片和负极金属接线片并 将上述部件紧固在一起的预应力螺杆， 两片所述压电陶瓷片和预应力螺杆之间 设置有绝缘套管。
[9] 在本发明所述的超声波牙刷中， 所述超声波换能器的频率为 30kHz〜70kHz。
[10] 在本发明所述的超声波牙刷中， 所述超声波换能器的频率为 40kHz。
[11] 在本发明所述的超声波牙刷中， 所述金属壳体开口处延伸出向外反折的折边。
[12] 在本发明所述的超声波牙刷中， 所述金属壳体为不锈钢材质。
[13] 在本发明所述的超声波牙刷中， 所述导线为带有屏蔽层的导线。
[14] 在本发明所述的超声波牙刷中， 所述牙刷本体的头部设置有刷毛。
[15] 在本发明所述的超声波牙刷中， 所述牙刷本体的头部为无刷毛式结构。 [16] 实施本发明的超声波牙刷， 具有以下有益效果：
[17] 1、 本发明的超声波牙刷釆用一体成型的牙刷本体， 超声波发生装置密封在牙 刷本体的头部， 具有很好的防水密封效果；
[18] 2、 电源釆用外置式电源， 可以提供超声清洗所需要的足够的功率；
[19] 3、 超声波换能器釆用双片压电陶瓷结构， 在较大功率和较高振幅的条件下具 有很好的机电转换效率， 保证超声清洗的实现；
[20] 4、 超声波换能器的频率在 30kHz~70kHz， 优选 40kHz， 处于该频率的超声波具 有空化腐蚀量小噪音低等优点；
[21] 5、 连接电源和超声波发生器的导线釆用带有屏蔽层的导线， 可以防止漏电以 及干扰， 使用更加安全可靠。
附图说明
[22] 下面将结合附图及实施例对本发明作进一步说明， 附图中：
[23] 图 1是本发明超声波牙刷的结构示意图；
[24] 图 2是本发明超声波牙刷中超声波发生装置立体示意图；
[25] 图 3是本发明超声波牙刷中超声波发生装置俯视图；
[26] 图 4图 3中 B-B剖视图；
[27] 图 5是本发明超声波牙刷中超声波发生装置的超声波换能器的立体示意图。
具体实施方式
[28] 如图 1所示， 在本发明的超声波牙刷的一个实施例中， 包括一体注塑成型的牙 刷本体 10、 密封在牙刷本体头部 11的超声波发生装置 20、 以及由牙刷主体 10中 引出的导线 30， 超声波发生装置 20和导线 40的一部分在牙刷主体 10注塑成型吋 封入牙刷主体 10内， 本发明的超声波牙刷还包括具有高频振荡信号输出的电源 (未示出） ， 导线 30连接超声波发生装置 20和电源， 本发明中的电源釆用可以 产生 30kHz〜70kHz高频振荡电压的公知的振荡电路， 优选可以产生 40kHz高频 振荡电压的振荡电路， 该电源和市电相连， 输出端接导线 30，该电源产生的电压 波形为近似正弦波， 该电压信号加载在超声波发生装置 20上， 由超声波发生装 置 20将电能转化成高频的机械振动。 电源的输出可以是间歇的或连续的。
[29] 如图 2〜图 4所示， 本发明的超声波牙刷的超声波发生装置包括外壳 21、 与外壳 21配合的上盖 22、 以及置于外壳 21内的超声波换能器。 相对现有的釆用压电陶 瓷片作为超声波发生器件， 换能器的功率要大一些， 能在口腔内引发空化效应 ， 从而达到超声波清洗的目的。 超声波换能器通过换能胶 32粘接固定在外壳 21 的内壁上， 所釆用换能胶是一种双组分树脂胶。
[30] 参看图 4和图 5， 本发明的超声波牙刷中的超声波换能器包括依次叠放在一起的 下金属盖板 26、 两片压电陶瓷片 24和 25和上金属盖板 23; 还包括设置在两片压 电陶瓷片 24和 25之间的正极金属接线片 27、 设置在上金属盖板 23和压电陶瓷片 2 4之间的负极金属接线片 28; 还包括穿过所述上金属盖板 23、 压电陶瓷片 24、 正 极金属接线片 25和负极金属接线片 26并将上述部件紧固在一起的预应力螺杆 29 ， 两片所述压电陶瓷片 24、 25和预应力螺杆 29之间设置有绝缘套管 30。 下金属 盖板 26上设置有与预应力螺杆 29配合的螺纹孔， 在实际应用中也可以和螺母配 合的方式紧固构成超声波换能器的部件。 正极金属接线片 27和负极金属接线片 2 8分别与导线 30的连接； 压电陶瓷片 25—面与正极金属接线片 27接触， 另一面通 过导电的预应力螺杆 29以及上金属盖板 23和下金属盖板 26与负极金属接线片连 通。 釆用金属接线片的而不是直接焊接在压电陶瓷片上的原因在于这样不会导 致因为高频振动而导致焊点脱焊。
[31] 本发明的超声波牙刷中的超声波换能器的频率为 30kHz〜70kHz，优选 40kHz，处 于该频率的超声波的空化作用腐蚀量和噪音都比较小， 适合牙齿的清洗。
[32] 为了使超声波发生装置 20牢固的密封在牙刷本体 10内，参看图 2和图 4， 外壳 21的 开口处延伸出向外反折的折边 31， 牙刷主体 10注塑成型吋， 折边 31嵌入牙刷主 体 10， 这种结构使得超声波发生装置 20和牙刷主体 10不会因为振动而脱离， 从 而影响超声波的传播。
[33] 在本发明的超声波牙刷中， 超声波发生装置的壳体 21为金属材质， 优选不绣钢 材质。
[34] 在本发明的超声波牙刷中， 刷头可以釆用无刷毛结构， 也可以釆用带有刷毛的 结构， 优选带有刷毛的结构， 刷毛可以防止刷头直接接触牙齿， 更舒适一点。
[35] 在本发明的超声波牙刷中， 导线 30釆用带有屏蔽层的导线， 屏蔽层和电源的地 线相连， 使本发明的超声波牙刷更加安全可靠。 [36] 在本发明的超声波牙刷中， 超声波发生装置可以是一个也可以是两个。
[37] 使用吋口腔内包一口清水或者漱口液， 将牙刷本体的头部伸入口腔， 打开电源 ， 超声波发生装置产生的超声波在口腔的液体内产生空化效应， 将牙齿上附着 的污垢冲击下来， 从而实现超声清洗的功效。
[38] 本发明的超声波牙刷， 结构简单可靠， 成本低， 非常适于家庭使用。
[39] 上面结合附图对本发明的实施例进行了描述， 但是本发明并不局限于上述的具 体实施方式， 上述的具体实施方式仅仅是示意性的， 而不是限制性的， 本领域 的普通技术人员在本发明的启示下， 在不脱离本发明宗旨和权利要求所保护的 范围情况下， 还可做出很多形式， 这些均属于本发明的保护之内。
