Description

电动牙刷
技术领域
本发明涉及牙刷用具技术领域，特别涉及一种电动牙刷。
背景技术
电动牙刷与普通牙刷相比，电动牙刷可以更彻底清除牙菌斑、减少牙龈炎、牙周病和牙龈出血等口腔疾病。具体的为电动牙刷通过电动机芯的快速旋转或震动，使刷头产生高频震动，瞬间将牙膏分解成细微泡沫，深入清洁牙缝；与此同时，刷毛的颤动能促进口腔的血液循环，对牙龈组织可进行按摩。
目前市面上的电动牙刷采用与普通牙刷相同的硬塑胶，手动的普通牙刷由于是人为控制，因此不会对口腔造成振动碰撞，但由于电动牙刷的震动是不受人为意识控制，电动机芯在快速旋转或震动时, 牙刷上的硬质塑胶会对牙齿和口腔等有接触部位由于高频震动碰撞而造成意外损伤。
发明内容
本发明的主要目的是提供一种电动牙刷，旨在提高电动牙刷使用的安全性。
为实现上述目的，本发明提出一种电动牙刷，其中，该电动牙刷包括牙刷本体及软质材料的套体，所述牙刷本体包括相连接的手柄和牙刷头，所述牙刷头连接有刷毛束，所述套体包括相连接的牙刷头套及牙刷柄套，所述牙刷头套至少部分包裹所述牙刷头，所述牙刷柄套至少部分包裹所述手柄，所述刷毛束穿过所述牙刷头套伸出所述牙刷头套外。
优选地，所述牙刷头套对应所述刷毛束设有开口，所述刷毛束由所述开口伸出所述牙刷头套外。
优选地，所述套体的材料为软质橡胶。
优选地，所述牙刷头套背离所述刷毛束一表面还设置有刷舌器。
优选地，所述套体的边角处设有过渡圆弧。
优选地，所述手柄上形成有台阶，所述牙刷柄套端部抵接所述台阶，所述牙刷柄套端部表面与所述台阶处表面平齐。
优选地，所述牙刷本体及所述套体为双色注塑一体成型。
优选地，该电动牙刷还包括电动组件。
本发明技术方案通过在牙刷头及与口腔接触的手柄部分包裹套体，通过软质材料的套体使硬质塑料的手柄和牙刷头与口腔进行隔离，使电动牙刷振动过程中，避免手柄和牙刷头对口腔的硬性高频震动碰撞，提高电动牙刷使用的安全性。

本发明提出一种电动牙刷。
参照图1至图6，图1为本发明电动牙刷一实施例的主视结构示意图；图2为本发明电动牙刷的左视结构示意图；图3为本发明电动牙刷的右视结构示意图；图4为本发明电动牙刷的牙刷本体结构示意图；图5为本发明电动牙刷的套体一立体结构示意图；图6为本发明电动牙刷的套体另一立体结构示意图。
请结合参照图1至图6，在本发明一实施例中，该电动牙刷包括牙刷本体10及软质材料的套体20，牙刷本体10包括相连接的手柄11和牙刷头12，牙刷头12连接有刷毛束13（参图4），套体20包括相连接的牙刷头套21及牙刷柄套22，牙刷头套21至少部分包裹牙刷头12，牙刷柄套22至少部分包裹手柄11，刷毛束13穿过牙刷头套21并伸出牙刷头套21外。
上述的牙刷本体10可由塑料制成，该塑料可为PP（聚丙烯）、PA（聚酰胺）、PC（聚碳酸酯）、PMMA（聚甲基丙烯酸甲酯）、ABS（丙烯腈-丁二烯-苯乙烯共聚物）、PS（聚苯乙烯）、PBT（聚对苯二甲酸丁二醇酯）、或PET（聚对苯二甲酸乙二醇酯）。优选采用与普通的手动牙刷相同的硬质塑料，便于节省材料研发和制造成本。套体20优选采用软质无害橡胶。刷毛束13为塑料制成，该塑料可为PP（聚丙烯）、PA（聚酰胺）、PC（聚碳酸酯）、PMMA（聚甲基丙烯酸甲酯）、ABS（丙烯腈-丁二烯-苯乙烯共聚物）、PS（聚苯乙烯）、PBT（聚对苯二甲酸丁二醇酯）、或PET（聚对苯二甲酸乙二醇酯），优选为硅胶和/或尼龙丝制成，可根据所选材料的硬度不同分为软毛、中毛、硬毛的刷毛束13，刷毛束13接触牙的一端外形可根据人体工程学设计，以便对牙齿的细缝进行全面清洁，如齿形或弧线形等。其中牙刷柄套22小于手柄11的长度的设计为牙刷本体10与口腔可能会接触的手柄11部分包裹有牙刷柄套22，其余手持手柄11的位置仍采用硬质塑料，以此节省橡胶材料，节约成本。
本发明技术方案通过在牙刷头12及与口腔接触的手柄11部分包裹套体20，通过弹性橡胶材质的套体20使硬质塑料的手柄11和牙刷头12与口腔进行隔离，使电动牙刷振动过程中，降低手柄11和牙刷头12对口腔的硬性高频震动碰撞，提高电动牙刷使用的安全性。
进一步地，套体20的材料为软质橡胶。其硬度可为60~70HS，使套体20的软硬度适中，能保持耐磨损性，电动牙刷高频振动时进行高效缓冲，使电动牙刷与口腔接触时对口腔内壁及牙龈进行保护，避免对口腔造成异物感刺激及损伤。
优选地，牙刷头套21对应刷毛束13设有开口211（参图5），刷毛束13由开口211伸出牙刷头套21外。套体20的边角处设有过渡圆弧24。
由于刷毛束13连接牙刷头12，牙刷头套21包裹牙刷头12，通过牙刷头12的开口使刷毛束13置于套体20外，刷毛束13与牙刷本体10连接的部分仍为硬质塑料，可便于牙刷本体10内部防水，刷毛束13间的污垢易于清理，开口211优选为略大于刷毛束13的开口，使牙刷头12的棱角能全部包裹在套体20内。手柄11由于一般采用为普通的硬质塑料，为提高手持牙刷的舒适度，在手柄11上的棱角部位也可包裹有套体22，手持手柄11的部分还可设有人体工程学曲面或防滑结构，以便于手持牙刷。通过套体20与口腔接触的表面均为过渡圆弧，适应于口腔的结构，对口腔不产生突兀感，提高刷牙的舒适性。
进一步地，牙刷头套21背离刷毛束13一表面还设置有刷舌器23。
其中，刷舌器23可为橡胶材质，为多条平行的弧形或线型等结构，刷舌器23与套体20可为一体成型结构，优选设于牙刷头套21与刷毛束13相反的一面上，使牙刷头12一面通过刷毛束13进行刷牙，另一面通过牙刷头套21的刷舌器23进行刷舌或口腔内壁等，以此增加牙刷的使用功能。
优选地，手柄11上形成有台阶14（参图4），牙刷柄套22端部抵接台阶14，牙刷柄套22端部表面与台阶14处表面平齐（参图1至图3）。
由于套体20部分包裹在牙刷本体10上，为防止套体20增大牙刷的外表面，设有与未设有套体20的交界处会产生凸起，通过凹设台阶14，套体20与牙刷本体10进行平滑连接，增强美观，使套体20与牙刷本体10紧密连接，不易脱落。
该电动牙刷还包括电动组件（未标示）。
其中，电动组件（未标示）可包括电机、可充电电池及防水结构等，使刷毛束13旋转或震动。电动组件（未标示）可容置于牙刷本体10内，通过电动组件（未标示）容置于牙刷本体10内部，进行防水。优选地，电动组件（未标示）单独设置，作为手柄11的一部分进行连接牙刷头12，并可拆卸，便于更换牙刷头12。
更进一步的，牙刷本体10及套体20为双色注塑一体成型。
上述的双射注塑可为双色成型机两只料管配合两套模具按先后次序经两次成型制成产品，使套体20与牙刷本体10紧密连接呈一体结构，减少加工工序，提高生产效率。套体20与牙刷本体10可为不同的颜色配合，增加其多样性。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
