Description

一种电动牙刷头和电动牙刷 技术领域
本实用新型涉及电动牙刷技术领域，特别是涉及一种电动牙刷头和电动牙刷。
背景技术
随着社会文明化，人们越来越对卫生、健康重视，因此日常必备的洁齿牙具有了很大的改进，从而出现了适合牙型的各种材料、各种形状的牙刷，还有便于携带的牙刷、电动牙刷等等新式牙刷，电动牙刷具有刷牙功能，但并不具备洗漱功能，用户在刷牙后还需要进行洗漱，整体使用不够方便，用户体验较差。
实用新型内容
基于此，有必要针对上述问题，提供一种电动牙刷头，用户可以在刷牙的过程中同时进行洗漱。
一种电动牙刷头，包括：
牙刷头体，所述牙刷头体上设有毛刷部，且所述牙刷头体上开设有若干个出水孔，所述牙刷本体内具有：第一出水通道，所述第一出水通道与各所述出水孔连通；
牙刷杆体，与所述牙刷头体一体设置，所述牙刷杆体内具有轴连接通道和第二出水通道，所述第二出水通道环绕所述轴连接通道设置，所述第二出水通道与所述第一出水通道密封连接。
上述电动牙刷头，通过出水孔的设置用户在刷牙时，可以同时进行洗漱，达到提升了用户的洗漱速度，提升了用户的使用体验。第二出水通道环绕轴连接通道设置，使得第二出水通道与轴连接通道隔开，避免水流进入轴连接通道与电动手柄的连接轴接触，对连接轴造成损坏。
在其中一个实施例中，所述牙刷头体具有：顶面、与所述顶面相对的底面、连接在所述顶面和所述底面之间的两个侧面，所述毛刷部设在所述顶面上，所述顶面和所述侧面上开设有若干出水孔。
在其中一个实施例中，所述顶面上具有：用于设置所述毛刷部的毛刷面，所述出水孔开设在所述毛刷面的两侧。用户在使用电动牙刷时，将电动牙刷头横置，此时顶面上的出水孔位于毛刷部的上方和下方，在刷牙时可以对牙齿和牙床同时进行清洁，配合刷牙，清洁效果较好，使用方便，大大提升用户的使用体验。
在其中一个实施例中，所述顶面上的出水孔开设在所述毛刷部的周侧。在使用时，毛刷部的四周都可以喷水，对牙齿和牙床具有较好的清洁作用。
在其中一个实施例中，所述侧面为弧形面。牙刷头体的侧面为弧形，出水孔均匀开设在弧形的侧面上，相较于平整的侧面，开设在弧形侧面上的出水孔的数量可以设置更多，喷水的角度更多，喷水可覆盖的区域更大，从而获得更好的清洁效果，更大的清洁效率，位于弧形侧面边缘的出水孔可以清洁口腔中的死角位置，清洁效果远超平整侧面上的出水孔。
在其中一个实施例中，所述牙刷杆体的底部开设有连接槽，所述连接槽与所述第二出水通道连通。电动手柄的顶面在连接电动牙刷头上时，先嵌入连接槽，再与第二出水通道和轴连接通道连接，保证连接的稳定性，可以较好的避免水漏出。
在其中一个实施例中，所述出水孔为圆形出水孔或锥形出水孔。出水孔可以为锥形，以设在顶面上的出水孔为例，出水孔在朝向顶面的方向上孔径逐渐减小，即出水孔中的水流汇聚到中心出喷出，可以起到增加水流压力的效果，同时可以使出水孔喷出的水流较细，避免各出水孔中的水流相互干扰，造成水流的能量损耗。
在其中一个实施例中，所述第二出水通道的内径大于所述第一出水通道的内径。第二出水通道流向出水孔的水逐渐集中，可以增大出水压力，同时第二出水通道的内径较粗可以避免出水断流的情况发生。
本实用新型还公开了一种电动牙刷，包括电动手柄和上所述的电动牙刷头，所述电动手柄内设有驱动组件和水泵组件，所述电动手柄与所述电动牙刷头连接时，所述驱动组件进入所述轴连接通道内，所述水泵组件与所述第二出水通道连通。
在其中一个实施例中，所述电动手柄上设有水泵开关键和水泵档位键，所述水泵档位键用于切换所述水泵组件的输出档位。用户可以通过触发水泵开关键来开启或关闭水泵，来启动或关闭喷水。也可以通过调节水泵档位键来改变出水孔的流量，来适应不同用户的需求。

其中牙刷杆体200内还具有轴连接通道220，第二出水通道210环绕轴连接通道220设置，使得第二出水通道210与轴连接通道220隔开，避免水流进入轴连接通道220与电动手柄的连接轴接触，对连接轴造成损坏。
牙刷头体100具有：顶面120、与顶面120相对的底面、连接在顶面120和底面之间的两个侧面130，其中毛刷部110设在顶面120上，在刷牙时，牙刷头体100的顶面120朝向用户的牙齿，牙刷头体100往复移动，对用户的牙齿进行清洁。牙刷头体100的顶面120上开设有若干出水孔300，在用户刷牙时或准备对对牙齿进行清洗时，可以将牙刷头体100的顶面120朝向牙齿，顶面120上的出水孔300喷水对牙齿和口腔进行清洗。其中，出水孔300的出水功能独立，用户可以在刷牙时启动出水孔300，同步进行牙齿清洗；用户也可以单独开启出水孔300，进行单独的牙齿清洗。
在一个实施例中，毛刷部110设置在顶面120上，并位于顶面120中部，顶面120上的出水孔300开设在顶面120，并位于毛刷部110的两侧，毛刷部110具有长度方向和宽度方向，本实施例中，出水孔300开设在毛刷部110宽度方向上的两侧，用户在使用电动牙刷时，将电动牙刷头横置，此时顶面120上的出水孔300位于毛刷部110的上方和下方，在刷牙时可以对牙齿和牙床同时进行清洁，配合刷牙，清洁效果较好，使用方便，大大提升用户的使用体验。
另一个实施例中顶面120上的出水孔300开设在毛刷部110的周侧，环绕毛刷部110设置，在使用时，毛刷部110的四周都可以喷水，对牙齿和牙床具有较好的清洁作用。
本实施例中，牙刷头体100上的两个侧面130上均开设有若干个出水孔300，在牙刷头在使用时，牙刷头体100横置，侧面130上的出水孔300可以将向上下两侧进行喷水，不仅可以对口腔内壁进行清洗，也可以使水快速的充满口腔， 达到洗漱作用。牙刷头体100可以呈方向或椭圆形，本实施例中的牙刷头体100呈椭圆形，当然在其他实施例中，牙刷头体100也可以为方形，本实施例中仅以牙刷头体100呈椭圆形为例做说明，牙刷头体100的侧面130为弧形，出水孔300均匀开设在弧形的侧面130上，相较于平整的侧面130，开设在弧形侧面130上的出水孔300的数量可以设置更多，喷水的角度更多，喷水可覆盖的区域更大，从而获得更好的清洁效果，更大的清洁效率，位于弧形侧面130边缘的出水孔300可以清洁口腔中的死角位置，清洁效果远超平整侧面130上的出水孔300。
其中出水孔300可以为多种形状，可以为圆形或方形或任意形状，本实施例中的出水孔300为圆形，多个圆形的出水孔300可以喷出密集的水流，对牙齿和空腔进行冲洗。在另一实施例中，出水孔300可以为锥形，以设在顶面120上的出水孔300为例，出水孔300在朝向顶面120的方向上孔径逐渐减小，即出水孔300中的水流汇聚到中心出喷出，可以起到增加水流压力的效果，同时可以使出水孔300喷出的水流较细，避免各出水孔300中的水流相互干扰，造成水流的能量损耗。
牙刷杆体200的底部开设有连接槽，电动手柄有部分可以嵌入连接槽内并插入牙刷杆体200，连接槽与第二出水通道210、轴连接通道220均连通，电动手柄的顶面120在连接电动牙刷头上时，先嵌入连接槽，再与第二出水通道210和轴连接通道220连接，保证连接的稳定性，可以较好的避免水漏出。
牙刷杆体200整体也呈锥形设置，其中牙刷杆体200靠近牙刷头体100的一侧较细，靠近电动手柄的一侧较粗，第二出水通道210的内径大于第一出水通道的内径。从第二出水通道210流向出水孔300的水逐渐集中，可以增大出水压力，同时第二出水通道210的内径较粗可以避免出水断流的情况发生。
本实施例中的电动牙刷头，在进行牙齿清洁时，可以同步喷水进行口腔清理，功能多样且清洁效果较好，清洁效率高。牙刷头体100可以多方向喷水，也可以清洁到口腔内的死角，不会发生漏水的情况。
本实用新型的第二实施方式公开了一种电动牙刷，包括电动手柄和第一实施方式中的电动牙刷头。电动手柄内设有驱动组件和水泵组件，电动牙刷头可拆卸地装配在电动手柄上，在电动牙刷头安装到电动手柄上时，驱动组件进入轴连接通道220内，可以带动电动牙刷头震动，进行牙齿刷洗。
电动手柄上具有水泵开关键和水泵档位键，用户可以通过触发水泵开关键来开启或关闭水泵，来启动或关闭喷水。也可以通过调节水泵档位键来改变出水孔300的流量，来适应不同用户的需求。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本实用新型的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。因此，本实用新型专利的保护范围应以所附权利要求为准。
