本发明以水下推进器的前进方向为上游，如图1a所示，本发明实施例提供一种水下推进器，包括动力部1、螺旋桨2，所述动力部1设在所述螺旋桨2的上游，用于驱动所述螺旋桨2转动，所述水下推进器还包括：进水部3，所述动力部1设置在所述进水部3的上游或内部，所述进水部3上设有进水口31，所述进水部3的一端和另一端呈柱状，所述进水部3的一端所在径向截面的直径向所述进水部3的另一端所在径向截面的直径逐渐增大；出水部4，所述出水部4设置在所述进水部3的下游，所述出水部4的一端设有出水口41；其中，所述进水部3与所述螺旋桨2相邻，设置在所述螺旋桨2的上游，所述螺旋桨2设置在所述出水部4的内部。本发明实施例通过设置进水部的一端所在径向截面的直径向进水部的另一端所在径向截面的直径逐渐增大，更多不同方向的水流从进水口进入到进水部中，在螺旋桨的作用下，通过出水口排出水而产生推动力，进而提高了水下推进器在使用时的导向稳定性，以及动能利用率，有效地提升了用户体验。
本发明一个实施例提供的水下推进器，如图2a所示，还包括导流部10，设于进水部3与出水部4之间，与进水部3、出水部4以对插式分别进行连接，用于将进入到进水部3的水均匀分散至螺旋桨2的叶片21上。具体来说，如图2b和2d所示，并且参照图2a，进水部3的另一端插接在导流部的一端13上，出水部4的另一端插接在导流部的另一端14上，从而进一步提高进水部3与出水部4之间的密封性。
本发明一个实施例提供的水下推进器，如图2c和2d所示，导流部10包括：导流壳体17；中心圆盘15；多个导向片16，导向片16沿着导流壳体17的圆周方向分布，连接导流壳体17与中心圆盘15，两个相邻的导向片形成导向通道16’。其中，导向片17与水下推进器的中轴线之间的夹角为10～15°，夹角的开口方向与螺旋桨2的叶片21的旋转方向一致，使得将进入到进水部3的水通过导向通道16’均匀分散至螺旋桨2的叶片21上。
本发明又一个实施例提供的水下推进器，如图3所示，出水部4的另一端与进水部3的另一端对应连接，其中出水部4的另一端与进水部3的另一端的端口截面保持一致，并且同为柱状，在两者进行连接后，可以有效地防止水流从两者的连接处流出。
本发明又一个实施例提供的水下推进器，如图3所示，出水部4的另一端与进水部3的另一端通过螺丝孔与螺丝的锁紧作用而连接。图4a是本发明又一个实施例水下推进器的正视图；图4b是本发明又一个实施例水下推进器的图4a在方向A上的剖视图。在出水部4与进水部3的轴向方向上设置螺丝孔与螺丝的连接方式，进一步加固了出水部4与进水部3的连接性，防止水流从两者的连接处流出。可选地，出水部4的另一端外部边缘处可以设置有螺纹，进水部3的另一端内部边缘处设置有螺纹，两者配合连接，本发明实施例不限于此。
本发明又一个实施例提供的水下推进器，如图3所示，进水部3的一端向进水部3的另一端在轴向方向呈弧线或直线延伸。也就是说，在进水部3的一端所在径向截面的直径向进水部3的另一端所在径向截面的直径逐渐增大的同时，呈弧线或直线延伸，使得当水下推进器在水下前行时，有效减小了前行时的阻力。
本发明一个实施例提供的水下推进器，如图2a所示，螺旋桨2设于进水口31与出水口41之间，动力部1如马达带动螺旋桨2转动，用于将进水部3中的水通过出水口41排出，同时从进水口31吸入水，相对于现有技术中存在将螺旋桨设置于水下推进器的底部，暴露在水中，本发明实施例将所述螺旋桨2设于所述进水口31与所述出水口41之间，有效减少了用户所面临的潜在的受伤风险。
本发明一个实施例提供的水下推进器，如图4a至4d所示，出水部4内部设有多片格栅42，用于将高速旋转的水导向成直线型，使得流向所述出水口41的水流比较集中，进而产生较大的推动力。
本发明又一个实施例提供的水下推进器，如图5a至5c所示，出水部4内部设有多片格栅42，用于将高速旋转的水导向成直线型。其中，出水部4内部还设有中心圆盘，格栅42连接于中心圆盘与出水部4的壳体之间，用于将经过螺旋桨2高速旋转后的水最大化导向呈直线型，使得流向所述出水口41的水流比较集中，进而产生较大的推动力。本发明实施例不限于此。
本发明一个实施例提供的水下推进器，进水口31的形状为条形、椭圆形，且多个进水口31均匀分布在进水部3的周向方向上，有利于不同方向的水流从进水口31进入到进水部3中。进水口31的形状不限于此。
本发明一个实施例提供的水下推进器，如图4d所示，进水口31的延伸方向与水下推进器的中轴线平行或呈一夹角，也可以理解为，当进水部3的一端向进水部的另一端在轴向方向呈弧线延伸时，进水部3的一端在轴向上的切线与进水部3的另一端在轴向上的切线呈一夹角α，夹角α可选为0～10°，使得所述水下推进器在前行过程中，水流可以从多个角度进入到所述进水口31。
本发明又一个实施例提供的水下推进器，如图1a、2a、3、4b、4d所示，出水部4的另一端所在径向截面的直径向出水部4的一端所在径向截面的直径逐渐减小，如图2a、4b所示，可选呈流线型或曲率延伸，结合进水部3的弧线延伸，进水部3与出水部4的连接处所在径向截面的直径最大，此时出水口41所在的出水部4的端口径向截面的直径小于出水部4的另一端口径向截面的直径，有利于当不同方向的水流从进水口31进入到进水部3时，螺旋桨2的转动带动更多的水流流向出水口41，使得出水口处的水流保持一定强度的集中，进而产生较大的推动力。其中，出水部4的另一端所在径向截面的直径与出水部4的一端所在径向截面的直径的比值为1～3。
本发明一个实施例提供的水下推进器，如图1a所示，动力部1设置在进水部3的内部，动力部1的上游设置有电子调速器5，电子调速器5的上游设置有电池6。当动力部1为无刷电机时，需要通过电子调速器5与电池6连接，以为动力部3提供能量。

本发明一个实施例提供的水下推进器，动力部1的外表面设置有导热层，用于传导和散发动力部1产生的热量。所述水下推进器具有防水功能。
综上所述，本发明提供的一种水下推进器，当控制部7启动，电池5向动力部1提供电能，电池6通过电子调速器5向动力部1提供电能，动力部1将电能转化成动能带动转轴转动，转轴带动螺旋桨2转动，将通过所述进水口31进入到所述进水部3中的水流引入至所述出水口41处，所述出水部4内部设有多片格栅42，用于将高速旋转的水导向成直线型，使得流向所述出水口41的水流比较集中，进而产生较大的推动力，带动水下推进器前行。通过设置进水部的一端所在径向截面的直径向进水部的另一端所在径向截面的直径逐渐增大，水下推进器在工作过程中将正前方和侧前方的水吸入，更多不同方向的水流从进水口进入到进水部中，从而产生向前的拉力，再加上在螺旋桨的作用下，通过出水口排出水而产生推动力，更加全面有效地利用该产品的动能，有效地提升了用户体验。
综上所述，本发明提供的上述实施例仅例示性说明本发明的原理及其功效，而非用于限制本发明。任何熟悉此技术的人士皆可在不违背本发明的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本发明所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本发明的权利要求所涵盖。
