Description

—种喷口可两头转换的喷嘴 - two conversion types spout nozzle

技术领域 FIELD

[0001] 本发明涉及用喷射即反作用原理达到推进的装置,具体涉及液体喷射推进器吸入口和喷射口的构造。 [0001] The present invention relates to a jet that is configured to promote the reaction principle of the device is reached, particularly relates to a liquid jet propulsion suction port and an injection port.

背景技术 Background technique

[0002] 喷流驱动的机器人常用于管状液体流道内的各种探测和清理作业,其中最常见的是血管机器人,如公开号为CN101961261A所公开的“一种射流驱动的血管机器人”和公开号为CN102125453A所公开的“一种清理血栓的血管机器人”。 [0002] The jet drive robot used in the liquid flow path within the tubular probe and various clean-up operations, the most common vascular robot, as disclosed in Publication No. CN101961261A to "a jet-driven vessels robot" and Publication No. CN102125453A disclosed as "a way to clean the blood vessel thrombosis robot." 上述血管机器人在狭长的血管内移动,如果调头反向移动则几乎不可能,因此需要推进系统中的喷嘴既承担吸流的作用,又承担喷流的作用。 Robot moves the blood vessel within the elongated vessel, if the reverse movement is nearly impossible to turn around, it is necessary to promote the action of the system to assume both the nozzles suction flow, and to assume the role of the jet. 由流体力学可知,吸流与喷流是两种不同的工况,吸流与喷流时液体与固体壁面之间的相互作用是不同的。 Seen from fluid mechanics, with the suction jet stream are two different operating conditions, the suction flow and the interaction between the liquid and the solid wall surface of the jets are different. 吸流时,希望喷嘴的端口变大,便于液体的聚集进而提高吸入效率;喷流时,希望喷嘴的端口变小,使液体在流道内逐渐增压后喷出。 When the suction flow, desired nozzle port becomes large, and thus facilitates aggregation liquid intake efficiency is improved; when jet desirable port smaller nozzles, the liquid is ejected after the gradual pressure increase in the flow path. 然而,上述两专利申请所述血管机器人两头的喷嘴内的流道都是一种直径由内向外逐渐减小的喇叭形。 However, the above two patent applications is the flow passage having a diameter gradually decreasing from the inside outwardly flared nozzle within the blood vessel of the two robots. 可见,虽然承担喷流的作用的喷嘴能使血液在流道内逐渐增压后喷出,但是由于承担吸流作用的喷嘴的吸入效率低,整个推进系统效率仍然无法提高。 Visible, although assume the role of the jet ejection nozzle can gradually pressurized blood in the flow path, but produces low suction efficiency because the suction action of the flow nozzle, still unable to promote the efficiency of the entire system is improved. 同理,如果将所述喷嘴反过来安装,即使其流道的直径由外向内逐渐减小,但承担喷流作用的喷嘴必然会失去增压喷射效果。 Similarly, if the nozzle is mounted, in turn, even though the diameter of the flow passage is gradually decreased from outside to inside, but assume the role of the nozzle spray bound to lose boost injection effect.

[0003] 综上所述,一种能根据所承担的作用,喷口可两头转换的喷嘴则成为本领域的渴求。 [0003] In summary, in accordance with one kind of action can be undertaken, two spout nozzles become converted desire in the art.
