Description

可换高效防护刀具
技术领域
本发明涉及一种由若干刀片组及其配套使用的刀片组固定架组合成的刀具，刀片组和固定架组合后可以切制食品等，主要用于炊事用具领域，也可以用于其他领域切制其他的被切物。
背景技术
一般人们加工饭菜都需要把菜蔬切割成片、丝、丁等形状。传统的菜刀费时费力加工精度很难把握，有时候不小心切到手，有时候菜蔬粘刀，有时候切辛辣菜蔬会让人很难受，有时候需要各种花样的加工方式，有时候需要切割面不在一个平面上。市场上的擦床使用时会对菜蔬有挤压的作用使加工后的菜蔬口感不佳。电动切菜机费电，不易维修不适合家庭和小型食堂使用。一般的刀具使用的时候，一部分有用的能量消耗在被切物上，另一部分被消耗在刀刃和案板上，造成刀刃和案板的损耗，大大地减少了刀刃和案板的使用寿命。实用新型专利申请号200920255826.7 结构是几把刀并列一起两侧各有一个手柄，需要双手操作。实用新型专利申请号： 200920001966.1，结构是几把刀并列一起在一个容器内使用。以上两个专利都是刀片之间的距离固定，不能够更换刀片组，切出来的菜蔬尺寸单一。实用新型专利申请号 201020293206.5结构是几把刀并列一起，刀片之间距离可以调节。结构复杂调节距离不好控制，维修不便，只有一个刀把且在外侧：不方便使用。
技术问题
为了能够解决以上问题，目前已经研制出了一种由有防护板的若干刀片组及其与其配套使用的刀片组固定架组合成的新式刀具，该刀具单手手工操作不用电可以极大的提高加工的速度、精度、质量、卫生，保证了使用者的安全性和舒适性。防护板保护刀刃的作用：该刀具使用时候，一部分有用的能量消耗在被切物上，另一部分被消耗在刀刃、刀刃的弹性、案板和防护板上，刀刃的弹性和防护板分担了部分的无用且有害的损耗能量，从而大大地延长了刀刃和案板的使用寿命。因为切割作用就是刀刃的功能与刀身关系不大，所以可以使用有弹性的特殊材料制作的'细线'替代刀刃使用。为简化语言特此声明：本发明所说的刀刃包括有弹性和没有弹性的的刀刃或者替代刀刃使用的特殊材料制作的有弹性的和没有弹性的'细线'。具体说就是提供一种切一到三次就可以把被切物切成片、丝或者丁的新式安全刀具。每一个单个的刀片组： 1、单个刀片之间的距离如果相等则被切物被等分； 2 、单个刀片之间的距离如果不相等被切物则不被等分 3 、所有的刀片可以等大也可以不等大4 、除了少数的的兼具稳固作用的刀片外，其它的刀片可以用同样起刀刃作用的弹性'细线'替代。替代刀刃使用的'细线'由特殊的材料制作，并且刀刃的宽度或者'细线'横截面的外切圆的直径小于3 毫米。每一个单个的刀片组可以单独设立自己的刀片距离，这样可以通过更换不同的刀片组实现使被切物厚薄大小不同的结果。防护板的高度在 3０毫米以内，并且防护板的高度要大于刀片组的高度。使用防护板和弹性刀刃或者同样起刀刃作用的弹性'细线'的配合作用可以大大地延长刀刃或者同样起刀刃作用的弹性'细线'和案板的使用寿命。
技术解决方案
词语解释： 锋面：是指所有的刀刃或者'细线'组成的切割面，锋利的切割面之意。 n: 是指５以内的任意的数字，可以是小数。'螺栓''螺母'：形象说法，它们并没有真正 的螺纹，它们只是方便插拔的光滑的柱体和筒体。因为案板不一定是完全的平面，防护板保护刀刃的方法：1 、被切割物完全被切断时候，锋面长于防护板下端n 毫米，锋面的弹性要足以让锋面躲进防护板的保护范围以内。 2、被切割物基本被切断时候，锋面和防护板下端处于同一平面内，锋面的弹性要求不高，n 毫米以内即可。3 、'藕断丝连'型被切割物不完全被切断时候，锋面短于防护板下端 n 毫米，锋面可以没有弹性或者弹性要求不高几毫米以内即可。具体说明：一种新式刀具由刀把 1 刀架 2 及刀片组 3 组成，刀把1 和刀架 2 在刀片组 3 的上方。刀片组 3 由外围的防护板 7 和若干的刀片组合而成，刀刃 4 的一面组成的锋面要与防护板配合好，刀背组成的钝面要短于防护板 1毫米以上；需要的时候每一个刀片 4 要有 n 毫米以内的弹性形变能力，不能让防护板 7 失去保护刀刃4的能力即可；每一个刀片本身有若干的小洞 10；防护板的外侧有可以被插入的'螺母' 6 。刀架下端侧面成'士' 或者' t '字型，'士'字上面一横是倒'凹'字型滑槽8，'士'字下面一横是起插入作用的'螺栓'9， '士'字一竖是刀架 2 。上述的一种新型刀具，其特征是，诉述的刀片组防护板7 上端的'凸'字形 5 滑入刀架下端的倒'凹'字型滑槽 8 ，刀架的'螺栓' 9 插入刀片组的'螺母' 6 。
有益效果
1 .结构简单，刀片薄矮小，节约加工材料、能源和时间。2 .菜蔬不粘刀 ，操作简单，安全舒适，适合家庭、食堂等场合使用。3.可以方便快速的切割洋葱、辣椒等特殊的辣眼睛的菜蔬。4.可以根据需要更换不同的刀片组，拆装方便，清洗容易。5.可以实现只是切一次就可以把被切物一次性切成片或者丝，切二次或者三次就可以把被切物切成丁的目的，不用再次切剁，最大程度的保持了菜蔬的营养成分。 极大的提高了工作效率。 6.由于防护板和弹性的刀刃或者'细线'的配合作用大大地延长了刀刃或者'细线'和案板的使用寿命，节能环保。7.单手臂的残疾人也可以使用：完全单手操作不用另一只手辅助工作。8. 一旦刀刃不好用了，可以把刀片组更换一个新的，刀架可以继续循环使用。9.因为本发明的出现，加工菜蔬也可以成为一种艺术：可以快速简单的进行各种花式加工，各种艺术造型。

本发明的最佳实施方式
很多人都喜欢吃饺子、包子等菜馅类食品，但是又被大量的切馅劳动吓到，现在本刀具解决了问题：只是需要很少的几刀就可以完成以前需要几十分钟才能完成的大量的切馅劳动。使用完全切断切丝型的刀片组，每一个刀刃的距离2毫米，相邻的4个刀刃组成的横断面为2 平方毫米的锋面：切一次被切物成为横断面 2 平方毫米的细丝，再切一次被切物就成为可以直接使用的 2立方毫米的小丁了。不用再次切剁，最大程度的保持了菜蔬的营养成分。
本发明的实施方式
下面以最简单的方案说明，不以此限定本发明的保护范围。
1.具体实施方案：<1>用图（3）的切片型刀片组：切一次则被切物成片；切二次则被切物成丝；切三次则被切物成丁。<2>用图（4）的切丝型刀片组：切一次则被切物成丝，切二次则被切物成丁。
2.根据吃饭人数不同使用型号不同的刀具：<1 > 3-5口之家使用小号刀具，锋面的横截面积 25 平方厘米以内的就可以 <2>食堂使用中号刀具，锋面的横截面积100 平方厘米左右的就可以 <3>更多人数的可以使用更大的尺寸的刀具。
3.单个刀片组可以根据人的口味和牙齿情况不同：有的人喜欢软一点的，有的人喜欢硬一点的；有人牙齿好，有人牙齿差。<1>需求一样的：设计成刀片之间的距离全部相等 <2>需求不一样的，刀刃之间的距离设定：一部分比较大的距离，另一部分比较小的距离。
4.根据被切物不同:肉类需要全部切断使用，适宜使用锋面长于防护板的刀片组;果蔬类可以使用锋面等于或者短于防护板的刀片组。
5.与其他的刀具效果对比：<1>假设最简单的切一个土豆。切片一般菜刀需要10刀，切丝需要 20 刀，切丁需要30刀；切片本刀具只是需要 1 刀，切丝只是需要1-2 刀，切丁需要2-3刀。 <2>擦床也是需要好多次才能够达到目的而且因为使用时挤压菜蔬的原因使其口味变差。
６. 使用本刀具不用怕洋葱、辣椒等菜蔬的辣眼睛了：只需要切 1-3刀就完事了。
7.如果只用一个刀刃，那么本刀具就是一种刀片很小的新式菜刀。
8.可以把锋面做成各种形状，原则上说，只要是二维平面上的图形应该都可以，只是锋面的加工难度比较高：1、简单的几何形状：三角形、四角形、五角形等、三边形、四边形五边形等，3、各种圆各种弧度等。复杂的图形比如各种小动物等等太多了就不一一列举了。
9.锋面可以是三维的：不在一个平面上方便各种造型,比如:锋面设计成"☆"但是中间是向上凹进的圆弧形状,一刀切下去西红柿就成为包括有五角的形状但是底部中间还是联系在一起的形状,摆放方便又好看。
10.使用本发明完全可以设计成为几大系列庞大的产品线，企业完全可以傲视全球20年！
