In addition, for convenience of explanation, the same reference numerals are assigned to the components having the same functions as the components described in the above-described embodiments, and the description thereof will not be repeated.
第五实施方式的电动牙刷刷头100D与第三实施方式的电动牙刷刷头100B的不同之处在于,卡合组件20D的结构不同于卡合组件20B的结构,具体将后述。The difference between the electric toothbrush head 100D of the fifth embodiment and the electric toothbrush head 100B of the third embodiment is that the structure of the engaging assembly 20D is different from that of the engaging assembly 20B, which will be described later.
请结合参阅图29-图33,在本实施方式中,电动牙刷刷头100包括刷头主体10D及卡合组件20D,卡合组件20D设置于刷头主体10D内。29-33, in this embodiment, the electric toothbrush brush head 100 includes a brush head body 10D and an engaging component 20D, and the engaging component 20D is disposed in the brush head body 10D.
在本实施方式中,刷头主体10D采用ABS、PP或POM,当然,在其他实施方式中,刷头主体10D也可以采用其他的材料。In this embodiment, the brush head body 10D is made of ABS, PP or POM. Of course, in other embodiments, the brush head body 10D can also be made of other materials.
该卡合组件20D包括主体30D,主体30D的靠近手柄200的一端即第一端沿第一方向X’开设有第一收容腔31,第一收容腔31用于收容驱动轴250的至少一部分,具体而言,第一收容腔31用于收容驱动轴250的第一金属部220。主体30D包括形成第一收容腔31的腔壁32,腔壁32凸设有抵接部320,抵接部320用于抵接驱动轴250。其中,抵接部320的弹性小,具有刚性,如此,无需再设置抵接于驱动轴250的弹性壁等结构。The snap-fit assembly 20D includes a main body 30D. One end of the main body 30D close to the handle 200, that is, the first end, is provided with a first receiving cavity 31 along the first direction X'. The first receiving cavity 31 is used for receiving at least a part of the drive shaft 250. Specifically, the first accommodating cavity 31 is used for accommodating the first metal portion 220 of the driving shaft 250 . The main body 30D includes a cavity wall 32 forming the first accommodating cavity 31 . The cavity wall 32 is protruded with an abutting portion 320 , and the abutting portion 320 is used for abutting against the drive shaft 250 . Among them, the abutting portion 320 has low elasticity and rigidity, and thus, there is no need to provide a structure such as an elastic wall abutting against the drive shaft 250 .
其中,主体30D的耐磨性高于刷头主体10D的耐磨性,使得无需设置从刷头主体10D分离且抵接于驱动轴250的弹性件。在本实施方式中,刷头主体10D的材料与卡合组件20D的主体30D的材料不同,且主体30D的材料耐磨性高于刷头主体10D的材料的耐磨性,第一方向X’为沿刷头主体10D的与手柄200连接的一端朝向刷头主体10D的远离手柄200的一端的方向。The wear resistance of the main body 30D is higher than that of the brush head main body 10D, so that there is no need to provide an elastic member separated from the brush head main body 10D and abutting against the drive shaft 250 . In this embodiment, the material of the main body 10D of the brush head is different from the material of the main body 30D of the engaging component 20D, and the wear resistance of the material of the main body 30D is higher than that of the material of the main body 10D of the brush head, the first direction X' The direction is along the direction of the end of the brush head body 10D connected to the handle 200 toward the end of the brush head body 10D away from the handle 200 .
当然,在其他实施方式中,主体30D的耐磨性高于刷头主体10D的耐磨性也可以通过 结构的设置来实现,只要主体30D的耐磨性高于刷头主体10D的耐磨性即可。Of course, in other embodiments, the wear resistance of the main body 30D is higher than the wear resistance of the brush head main body 10D can also be achieved through the arrangement of the structure, as long as the wear resistance of the main body 30D is higher than that of the brush head main body 10D That's it.

When the driving shaft 250 of the handle 200 is inserted into the first accommodating cavity 31 , the driving shaft can be stably moved. The 250 is engaged in the first accommodating cavity 31 and is not easy to fall off, so that the drive shaft 250 and the abutting portion 320 fit more closely, thereby making the vibration effect of the electric toothbrush head 100 better.
另外,本发明的电动牙刷刷头100D是通过腔壁32上设置的抵接部320直接抵接于驱动轴250的,没有设置从刷头主体10D分离且抵接于驱动轴250的弹性件、抵接于驱动轴250的弹性壁等结构,如此,能够有效确保电动牙刷300在使用时的稳定性,且外观效果佳。结构简单,无需额外设置弹性件等结构,能够有效简化制造工序,降低生产成本。In addition, the brush head 100D of the electric toothbrush of the present invention directly abuts the drive shaft 250 through the abutment portion 320 provided on the cavity wall 32 , and does not provide an elastic member, Structures such as the elastic wall abutting against the drive shaft 250 can effectively ensure the stability of the electric toothbrush 300 during use, and the appearance effect is good. The structure is simple, and no additional structure such as an elastic member is required, which can effectively simplify the manufacturing process and reduce the production cost.
