具体实施方式detailed description
如图1-9所示，一种电动剃须刀的刀头组件，包括有网罩1、刀架2，其中，网罩1包括有支撑环11以及外刀网12、内刀网13，内刀网13、外刀网12、支撑环11以及刀架2均同轴设置，刀架2上对应外刀网12位置设有外刀片21，刀架2上对应内刀网13位置设有内刀片22，外刀片21与外刀网12可相互配合切削，内刀片22与内刀网13可相互配合切削，外刀片21和内刀片22的数量可以根据需要自行设定，在此，本发明具体实施例不再做详细阐述，外刀网12的内圈与内刀网13的外圈连接成一体，本发明具体实施例中，内刀网13只设置一环，当然，也可以设置两环或者更多，当设置两环以上时，相邻两个内刀网13的内圈和外圈一体连接即可；As shown in Figures 1-9, a cutter head assembly of an electric shaver includes a net cover 1 and a knife holder 2, wherein the net cover 1 includes a support ring 11, an outer knife net 12, an inner knife net 13, The inner knife net 13, the outer knife net 12, the support ring 11 and the knife rest 2 are all arranged coaxially. The knife rest 2 is provided with an outer knife 21 at the position corresponding to the outer knife net 12, and the knife rest 2 is provided with an inner knife net 13 at the position. The inner blade 22, the outer blade 21 and the outer blade net 12 can cooperate with each other for cutting, the inner blade 22 and the inner blade net 13 can cooperate with each other for cutting, and the number of the outer blade 21 and the inner blade 22 can be set according to the needs. The specific embodiment of the invention will not be described in detail. The inner ring of the outer knife net 12 and the outer ring of the inner knife net 13 are connected into one body. In the specific embodiment of the present invention, the inner knife net 13 is only provided with one ring. Two rings or more, when more than two rings are provided, the inner ring and the outer ring of two adjacent inner knife nets 13 can be integrally connected;
外刀网12的外圈与支撑环11之间设有若干个连接片14，连接片呈“7”字形，相邻连接片14之间间隔设置形成镂空部15，外刀网12由若干个锯齿121围成环状，各锯齿121位于同一平面上，外刀网12的厚度d1大于内刀网13的厚度d2，外刀片21的最外端211位于外刀网12上锯齿121齿尖1211的内侧，这样在使用时，可以避免外刀片21与皮肤接触，划伤皮肤，使用更加安全；外刀网12上各锯齿121的齿尖1211位于支撑环11内圈面的内侧，这样可以增大镂空部15的空间，便于更多毛发进入网罩1内。A number of connecting pieces 14 are arranged between the outer ring of the outer knife net 12 and the support ring 11. The connecting pieces are in the shape of a "7". The adjacent connecting pieces 14 are spaced to form hollow parts 15. The outer knife net 12 is composed of several The serrations 121 are surrounded by a ring, each serration 121 is located on the same plane, the thickness d1 of the outer knife net 12 is greater than the thickness d2 of the inner knife net 13, and the outermost end 211 of the outer blade 21 is located on the outer knife net 12. In this way, when using, the outer blade 21 can be prevented from contacting the skin, scratching the skin, and the use is safer; The space of the large hollow part 15 is convenient for more hairs to enter the mesh cover 1 .
为了提高外刀网12与支撑环11之间连接的强度，可以增大连接片14的宽度，但是，为了避免因连接片14宽度过大影响过长头发进入镂空部15，本发明具体实施例中，各连接片14上均开设有缺口141，这样过长头发可以从开口141处进入网罩1内。In order to improve the strength of the connection between the outer knife net 12 and the support ring 11, the width of the connecting piece 14 can be increased. However, in order to prevent the excessively long hair from entering the hollow part 15 due to the excessively large width of the connecting piece 14, the specific embodiment of the present invention In the middle, each connecting piece 14 is provided with a gap 141 , so that excessively long hair can enter the mesh cover 1 from the opening 141 .
本发明具体实施例中，外刀网12上各锯齿121的齿尖1211处设有弧形引导面12110，外刀网12上相邻两锯齿121的齿根1212之间经弧面连接12120，这样既可以防止齿尖1211或者相邻锯齿121的齿根1212连接位置划伤皮肤，又可以使得舒适感更强。In the specific embodiment of the present invention, the tooth tips 1211 of the teeth 121 on the outer knife net 12 are provided with arc-shaped guide surfaces 12110, and the tooth roots 1212 of two adjacent teeth 121 on the outer knife net 12 are connected by an arc surface 12120, This can not only prevent the tooth tips 1211 or the connecting positions of the tooth roots 1212 of the adjacent serrations 121 from scratching the skin, but also enhance the comfort.
为了进一步避免齿尖在使用时损伤皮肤，在外刀网上各锯齿121的齿尖1211至少向上或向下设置弧面，如图10所示，锯齿121的齿尖1211向上设置弧面12111，如图11所示，锯齿121的齿尖1211向下设置弧面12111，如图12所示，锯齿121的齿尖1211向上和向下均设置弧面12111。In order to further prevent the tooth tips from damaging the skin during use, the tooth tips 1211 of the serrations 121 on the outer knife net are at least upwardly or downwardly provided with arc surfaces, as shown in FIG. As shown in 11, the tooth tips 1211 of the saw teeth 121 are provided with arc surfaces 12111 downward. As shown in FIG. 12, the tooth tips 1211 of the saw teeth 121 are provided with arc surfaces 12111 both upward and downward.
为了进一步提高切削效果，各锯齿121的中心线L偏离外刀网12的中心O位置，这样在使用时，刀片与锯齿121之间可以形成切削夹角，切削更快。In order to further improve the cutting effect, the center line L of each serration 121 deviates from the center O of the outer knife net 12, so that when in use, a cutting angle can be formed between the blade and the serration 121, and the cutting is faster.
