Description
技术领域technical field
本发明关于一种导引装置，尤其是指一种可藉由旋转运动将液体形成线性位移运动加速排出的旋转导引液体装置。The present invention relates to a guiding device, in particular to a rotating liquid guiding device which can form a linear displacement motion and accelerate discharge of the liquid through a rotating motion.
现有技术current technology
传统的内螺旋输送装置通常藉由一中空管体内壁中结合一内衬橡胶，再以轴向方向加入一螺旋叶片，最后由一动力源直接连接该螺旋叶片带动转动，将中空管体内的固体或液体以该螺旋叶片进行输送。但上述传统的内螺旋输送装置在输送时，会产生外漏、流速不稳且经常故障的缺失。The traditional internal screw conveying device is usually combined with a lining rubber in the inner wall of a hollow tube, and then a screw blade is added in the axial direction, and finally a power source is directly connected to the screw blade to drive the rotation, and the hollow tube body The solid or liquid is conveyed by the helical blade. However, when the above-mentioned traditional internal screw conveying device is conveying, there will be leakage, unstable flow rate and frequent failures.
基于上述缺失，有业者设计将螺旋叶片外侧与中空管体内壁直接进行固定连接且为一平整切面，使该螺旋叶片与该中空管体藉由动力源而直接一体转动。但上述内螺旋输送装置却是因固体或液体无法在螺旋叶片与中空管体的平整切面下产生流速差，使入口侧的固体或液体不易进入该内螺旋输送装置中，相对效能较差。因此，针对上述习知内螺旋输送装置所存在的问题点，如何开发一种更具理想实用性的创新结构，实使用消费者所殷切企盼，亦系相关业者须努力研发突破的目标及方向。Based on the above-mentioned deficiency, some manufacturers have designed to directly connect the outer side of the helical blade to the inner wall of the hollow tube with a flat cut surface, so that the helical blade and the hollow tube body can be directly rotated together by a power source. However, the above-mentioned internal screw conveying device is relatively poor in efficiency because the solid or liquid cannot generate a flow velocity difference under the flat section of the helical blade and the hollow pipe body, so that the solid or liquid at the inlet side is difficult to enter the internal screw conveying device. Therefore, in view of the problems existing in the above-mentioned conventional internal screw conveying devices, how to develop a more ideal and practical innovative structure, which is eagerly awaited by consumers, is also the goal and direction that related companies must work hard to develop breakthroughs.

请参阅图2至图7B所示，其为本发明液体导引装置数个较佳实施例的立体结构及正视结构示意图。于上述实施例中，该主叶体52的该宽度w的尺寸与该管体51内缘半径r的尺寸为相等，而图2所示中，由于该主叶体52a的该宽度w1的尺寸小于该管体内缘半径r的尺寸，因此会使该液体导引装置5a形成有一中空部54直接连通该入口侧511以及该出口侧512。Please refer to FIG. 2 to FIG. 7B , which are three-dimensional structure and front view structure diagrams of several preferred embodiments of the liquid guiding device of the present invention. In the above-mentioned embodiment, the size of the width w of the main blade body 52 is equal to the size of the radius r of the inner edge of the tube body 51, and as shown in FIG. 2, due to the size of the width w1 of the main blade body 52a The dimension is smaller than the radius r of the inner edge of the tube, so the liquid guiding device 5 a is formed with a hollow portion 54 directly communicating with the inlet side 511 and the outlet side 512 .
再参阅图3A及图3B所示，不仅该主叶体52b的该宽度w2的尺寸小于该管体内缘半径r的尺寸，而且该管体51上更具有一导通管体55，该导通管体55为一中空圆柱，且外缘表面与该主叶体52b相结合。因此不仅该导通管体55直接连通该入口侧511以及该出口侧512，亦可用以直接连接该传动部4(图中未示出)。于本发明较佳实施例中 ，该主叶体52b更具有一开口523，该开口523具有一顶点524，且自该顶点524二侧分别具有一第三曲线525以及一第四曲线526延伸至该出口侧512，该顶点524定义为与该出口侧512相距有一间距s且位于该管体51内缘表面上，该第三曲线525定义为以该主叶体52b的螺旋曲线形状延伸至该出口侧512的螺旋曲线，该第四曲线526定义为自该顶点524延伸至相交于该出口侧512与该主叶体52b邻靠该中心轴50的一端点527的弧形连续曲线。由以上设计，不仅该液体2至该出口侧512排出阻力减少，亦可使该液体导引装置5b可进行不同方向(顺时针方向及逆时针方向)旋转达到相同功效。Referring to Fig. 3A and Fig. 3B again, not only the size of the width w2 of the main blade body 52b is smaller than the size of the radius r of the inner edge of the tube, but also the tube body 51 has a conduction tube body 55, the conduction tube body 51 The tube body 55 is a hollow cylinder, and the outer edge surface is combined with the main blade body 52b. Therefore, not only the conduit body 55 directly communicates with the inlet side 511 and the outlet side 512 , but also can be used to directly connect with the transmission part 4 (not shown in the figure). In a preferred embodiment of the present invention, the main blade body 52b further has an opening 523, the opening 523 has a vertex 524, and respectively has a third curve 525 and a fourth curve 526 extending from the two sides of the vertex 524 to On the outlet side 512, the apex 524 is defined as having a distance s from the outlet side 512 and is located on the inner edge surface of the pipe body 51, and the third curve 525 is defined as extending to the For the helical curve of the outlet side 512 , the fourth curve 526 is defined as an arc-shaped continuous curve extending from the apex 524 to an end point 527 intersecting the outlet side 512 and the main blade body 52 b adjacent to the central axis 50 .

上述数个实施例的每一该主叶体52、52a、52b为绕该中心轴50旋转的一螺旋曲线形状，且自该管体51内缘表面沿该中心轴50延伸有一宽度w的螺旋曲面形状。而以下所述的数个实施例中，如图4至图7B所示，与上述数个实施例不同的是，皆是将每一该主叶体52c、52d、52e、52f设计为一直线形状，且自该管体51内缘表面沿该中心轴延伸有一宽度w，而该主叶体52c、52d、52e、52f亦为结合于该管体51内缘表面上，且该主叶体52c、52d、52e、52f一端面521a与该入口侧511相距有一距离d。。Each of the main blade bodies 52, 52a, 52b in the above-mentioned several embodiments is in the shape of a helical curve rotating around the central axis 50, and extends from the inner surface of the tube body 51 along the central axis 50 in a helical shape with a width w. surface shape. In the several embodiments described below, as shown in Fig. 4 to Fig. 7B, different from the above several embodiments, each of the main blade bodies 52c, 52d, 52e, 52f is designed as a straight line shape, and extend from the inner edge surface of the tube body 51 along the central axis with a width w, and the main leaf bodies 52c, 52d, 52e, 52f are also combined on the inner edge surface of the tube body 51, and the main leaf body One end surface 521a of 52c, 52d, 52e, 52f is separated from the inlet side 511 by a distance d. .
请先参阅图4所示，复数个主叶体52c的数量为二个，且为交错排列，而该主叶体52c的该宽度w的尺寸与该管体51内缘半径r的尺寸为相等，因此会使复数个主叶体52c相交在该中心轴50的一点上。每一该辅叶体53a二侧分别具有一第一曲线531a以及一第二曲线532a，该第一曲线531a定义为以该主叶体52c的直线形状延伸至该入口侧511，该第二曲线532a定义为自该主叶体52c邻靠该中心轴50的一端点522a延伸至与该第一曲线531a相交于该入口侧511的弧形连续曲线。请再参阅图5所示，复数个主叶体52d的数量为二个，且为交错排列，但由于该主叶体52d的该宽度w1的尺寸小于该管体内缘半径r的尺寸，因此会使该液体导引装置5d形成有一中空部54a直接连通该入口侧511以及该出口侧512。Please refer to Fig. 4 first, there are two main leaf bodies 52c arranged in a staggered manner, and the size of the width w of the main leaf bodies 52c is equal to the size of the radius r of the inner edge of the tube body 51 , so the plurality of main blades 52c intersect at one point on the central axis 50 . Both sides of each auxiliary vane 53a have a first curve 531a and a second curve 532a respectively, the first curve 531a is defined as extending to the inlet side 511 in the straight line shape of the main vane 52c, and the second curve 532a is defined as an arc-shaped continuous curve extending from an end point 522a of the main blade body 52c adjacent to the central axis 50 to intersecting the first curve 531a at the inlet side 511 . Please refer to Fig. 5 again, there are two main leaf bodies 52d arranged in a staggered manner, but since the width w1 of the main leaf bodies 52d is smaller than the radius r of the inner edge of the tube, it will The liquid guiding device 5 d is formed with a hollow portion 54 a directly communicating with the inlet side 511 and the outlet side 512 .
而图6所示，复数个主叶体52e的数量为三个，且为交错排列，而该主叶体52e的该宽度w的尺寸与该管体51内缘半径r的尺寸为相等，因此会使复数个主叶体52e相交在该中心轴50的一点上。如图7A及图7B所示，复数个主叶体52f的数量为三个，且为交错排列，而该主叶体52f更具有一弧槽528，而藉由复数个弧槽528的排列，使沿进入该中心轴50方向形成有一圆形形状，并直接连通该入口侧511以及该出口侧512。As shown in Figure 6, the number of the plurality of main blade bodies 52e is three, and they are arranged in a staggered manner, and the size of the width w of the main blade body 52e is equal to the size of the inner edge radius r of the tube body 51, so A plurality of main vanes 52e intersect at one point of the central axis 50 . As shown in FIG. 7A and FIG. 7B, the number of the plurality of main blades 52f is three, and they are arranged in a staggered manner, and the main blades 52f further have an arc groove 528, and by the arrangement of the plurality of arc grooves 528, A circular shape is formed along the direction entering the central axis 50 , and directly communicates with the inlet side 511 and the outlet side 512 .
惟，以上所述仅为本发明的较佳实施例而已，非因此即拘限本发明的专利范围，故举凡运用本发明说明书及图式内容所为的简易修饰及等效结构变化，均应同理包含于本发明的专利范围内，合予陈明。However, the above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the description and drawings of the present invention should be In the same way, it is included in the patent scope of the present invention, and it is stated together.
