Description
Technical field
The present invention relates to spraying is the device that the principle of reaction reaches propelling, is specifically related to the structure of liquid jet propeller suction inlet and jet.
Background technology
The robot that jet flow drives is usually used in various detections and the prune job in the tubulose flow channel for liquids, wherein modal is vascular micro-robot, is that CN101961261A disclosed " a kind of jet-driven vascular micro-robot " and publication number are CN102125453A disclosed " a kind of vascular micro-robot of clearing up thrombosis " such as publication number.Above-mentioned vascular micro-robot is mobile in long and narrow blood vessel, if tune oppositely mobile hardly may, therefore need the nozzle in the propulsion system both to bear the effect of inhaling stream, bear again the effect of jet flow.By hydrodynamics as can be known, inhaling stream and jet flow is two kinds of different operating modes, inhales that the interaction between the liquid and solid wall surface is different when flowing from jet flow.When inhaling stream, wish that the port of nozzle becomes large, be convenient to the gathering of liquid and then improve suction efficiency; During jet flow, wish that the port of nozzle diminishes, liquid is sprayed after the supercharging in runner gradually.Yet, the runner in the nozzle at the described vascular micro-robot of above-mentioned two patent applications two all be a kind of diameter reduce gradually from inside to outside tubaeform.As seen, although bear the nozzle of the effect of jet flow blood is sprayed gradually in runner after the supercharging, because it is low to bear the suction efficiency of the nozzle of inhaling the stream effect, whole propulsion system efficient still can't improve.In like manner, if described nozzle is installed conversely, even the diameter ecto-entad of its runner reduces gradually, but the nozzle of bearing sedimentation exhalation will inevitably lose the boosting jet effect.
In sum, a kind of can be according to the effect of bearing, but the nozzle of spout two conversion then becomes craving for of this area.
Summary of the invention
In view of there is above-mentioned deficiency in prior art, but technical problem to be solved by this invention provides the nozzle of a kind of spout two conversion, this nozzle can be realized inhaling stream according to bearing of task and change with the function of jet flow, significantly improves the mobile efficient of the people's direct motion of jet flow driven machine and backward.
The technical scheme that the present invention addresses the above problem is:
But the nozzle of a kind of spout two conversion, this nozzle comprises housing, it is characterized in that, described housing is tubulose, be provided with slip ring in it, after an elastic tube passed through the centre bore tensioning of slip ring, the head of housing was fixed at two, the endoporus that the makes elastic tube expansion that after leaving the side of described slip ring, outwards stretches gradually, formation one closed cavity between the inwall of the outer wall of elastic tube and housing; The periphery of described slip ring and the inwall of housing are divided into two closed cavity in the middle of described movingly; Two of described housing is respectively equipped with the through hole that is communicated with the closed cavity of described slip ring both sides.
For make described slip ring can be as best one can near the end of housing, the both ends of described housing are embedded with respectively annular end cap, the centre bore edge of this end cap is provided with cannelure, by annular small end cover the head of described elastic tube is pressed in the set cannelure in the centre bore edge of end cap; Described through hole passes through described annular end cap and is communicated with the closed cavity of described slip ring both sides by the end of described housing.
Produce gauffer and increase the flow resistance of liquid through the centre bore of slip ring the time for fear of elastic tube, the external diameter of described elastic tube preferably equates with the aperture of the centre bore of described slip ring.
By the structure of nozzle of the present invention as seen, when injecting fluid media (medium) (liquid or gas) in the closed cavity of slip ring one side, described slip ring just moves to the other end by one of nozzle, and then two conversion of realization spout, in order to realize inhaling stream and flow-jetting function conversion according to bearing of task.Therefore, when the propulsion system that adopts nozzle of the present invention to consist of was used for jet flow driven machine people, the jet flow driven machine people who obtains was that direct motion or backward all have higher mobile efficient.
Description of drawings
Fig. 1 and Fig. 2 are the structural representation of a specific embodiment of nozzle of the present invention, and wherein, Fig. 1 is front view (the A-A rotation of Fig. 2 is cutd open), and dotted line represents that slip ring 2 is positioned at the state of housing 1 right head among the figure, and Fig. 2 is left view.
Fig. 3 is the jet flow driven machine people's of use nozzle of the present invention schematic diagram, and dotted line represents pipeline among the figure.
Fig. 4 is the structural representation of another specific embodiment of nozzle of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, whole nozzle is comprised of housing 1, slip ring 2, elastic tube 3 and end cap 4, and wherein, housing 1 is one section tubular structure, and both ends of the surface are provided with the cannelure that embeds end cap 4, and the side at two is provided with through hole 5; Slip ring 2 is annular, and it is located in the housing 1, and the inwall of periphery and housing 1 movingly; Elastic tube 3 is made greater than 50% linear low density polyethylene by elastic extension, and the equal diameters of the centre bore of external diameter and slip ring 2, it passes through after the centre bore tensioning of slip ring 2 two outwards stretch expansion and flange, then described flange is compressed and is fixed in the cannelure of housing 1 end face by screw 6 by end cap 4; The hole equals the annular of housing 1 internal diameter of tubulose centered by the described end cap 4.
As seen from Figure 1, form a closed cavity 7 between the inwall of the outer wall of elastic tube 3 and housing 1, this closed cavity 7 is divided into two by slip ring 2, and the through hole 5 of side, housing 1 two is communicated with the closed cavity 7 of slip ring 2 both sides respectively.
Referring to Fig. 3 and in conjunction with Fig. 1, when jet flow driven machine people 8 moves right, the slip ring 2 that first will be positioned at the nozzle 10 of jet flow driven machine people 8 left heads by propulsion control system 9 is pushed into the left head of housing 1, it is the state shown in the solid line among Fig. 1, simultaneously the slip ring 2 in the nozzle 10 of jet flow driven machine people 8 right heads is pushed into the right head of housing 1, i.e. state shown in dotted lines in Figure 1.Otherwise when jet flow driven machine people 8 is moved to the left then.By top description as seen, the nozzle 10 at two, jet flow driven machine people 8 left and right sides can carry out jet flow and the conversion of inhaling the stream function according to travel direction, significantly improves jet flow driven machine people 8 direct motion and the mobile efficient of backward.
Referring to Fig. 4, for make described slip ring 2 can be as best one can near the end of housing 1, this example has been done following improvement on the basis of embodiment illustrated in figures 1 and 2: make the diameter of end cap 4 centre bores less than the diameter of tubular shell 1 endoporus, namely increase the annulus area of end cap 4, be communicated with the closed cavity 7 of slip ring 2 both sides by the end of housing 1 so that two through hole 5 passes through end cap 4; Correspondingly, process a cannelure in the edge of the centre bore of end cap 4, adopt annular small end cover 11 in the same mode of embodiment illustrated in figures 1 and 2, two of elastic tube 3 is pressed in the cannelure set on the end cap 4.
