Detailed description of the invention
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail. It should be noted that, in the situation that not conflicting,Feature in embodiment and embodiment in the application can combine mutually.
It should be noted that the term that used is only in order to describe detailed description of the invention here, but not intention restriction is according to this ShenIllustrative embodiments please. As used herein, unless context explicitly points out in addition, otherwise singulative is also intended toComprise plural form, in addition, it is to be further understood that when using in this manual while belonging to " comprising " and/or " comprising ", itsIndicate and have feature, step, operation, device, assembly and/or their combination.
In the present invention, upper and lower to refer to the upper and lower of Clean-suction nozzle under in working order to, front and rear direction refers toClean-suction nozzle direction consistent with the fore-and-aft direction of cleaning cart in working order time, left and right directions is the right and left during in the face of frontTo.
Introducing as background technology, there is the poor technical problem of the service behaviour of Clean-suction nozzle in prior art. For solvingThis technical problem, inventor explores and analyzes the poor reason of Clean-suction nozzle service behaviour of above prior art.While finding the operating speed quickening of cleaning cart, the Clean-suction nozzle of prior art picks up action time minimizing to the suction of rubbish, more and moreMany rubbish does not suck suction inlet in time just from suction nozzle bottom " escape ", and the rubbish meeting showed increased that causes suction nozzle rear portion to omit is cleanCar clean-up performance less stable, along with its capacity variation that absorbs rubbish of variation of operating speed is larger, when operating speed increasesTime, its ability that absorbs rubbish sharply reduces; And the variation of the Clean-suction nozzle terrain clearance of prior art has directly affected suction nozzleSuction, when travelling to pavement roughness road conditions, suction nozzle suction is unstable, heap shape rubbish is intermittently leaked in suction inlet below.
Fig. 3 is the suction inlet front air motion schematic diagram of the Clean-suction nozzle of prior art. As shown in Figure 3, by hydrodynamics machineManage known, air-flow after the road clearance in suction inlet front enters, have obvious subsides ground motion trend (effect phenomenon near the ground,See a district that in Fig. 3, A air-flow forms), cause the relatively low whirlpool of formation speed in suction nozzle inner chamber, see B air-flow in Fig. 3.The effect in the air-flow a near the ground district being formed by A air-flow is to kick up ground refuse to suction nozzle inner chamber, when ground refuse thicker or clearThe operating speed of clean car is very fast, causes part rubbish not kick up from ground. Formed the b district that is positioned at inner chamber top by B air-flow,The air velocity in this b district is lower, is unfavorable for making the rubbish of kicking up to be transported in suction inlet, causes rubbish to be accumulated in suction nozzle inner chamber,Reduce pumping efficiency.
For above technical problem, on the above basis of exploring and analyze, inventor has proposed a kind of Clean-suction nozzle.
As shown in Fig. 4 to Figure 11, Clean-suction nozzle of the present invention comprises housing, suction inlet and gas supplementing opening. Housing has suction nozzle inner chamber.Suction inlet is arranged at the top of housing and is communicated with suction nozzle inner chamber. The top that gas supplementing opening is arranged at housing is communicated with suction nozzle inner chamber, and,Gas supplementing opening is than the edge, front of the more close suction nozzle inner chamber of suction inlet.
Fig. 8 is the suction inlet front air motion schematic diagram of the Clean-suction nozzle of the first embodiment. Below in conjunction with Fig. 8, the present invention is describedThe advantage of Clean-suction nozzle.
This Clean-suction nozzle is designed with gas supplementing opening on suction nozzle, and the top that gas supplementing opening is arranged at housing is communicated with suction nozzle inner chamber, and,Gas supplementing opening is than the edge, front of the more close suction nozzle inner chamber of suction inlet. From hydrodynamics mechanism, under the effect of suction nozzle inner chamber negative pressure,Air-flow, from suction nozzle chamber outer wall enters, can form the air-flow that one flow velocity is higher. Under fluid viscosity effect, compared with high gas flow meetingDrive its air motion around, near air speed improving. When air-flow enters suction from the gas supplementing opening at the top, front of housingAfter mouth inner chamber, can form one high velocity air and flow to suction nozzle intracavity bottom, paste after ground motion one segment distance, upwards promote and enter suctionMouthful, therefore, for the Clean-suction nozzle of prior art, the high velocity air that enters suction nozzle inner chamber by gas supplementing opening is (in Fig. 8C air-flow) can improve air-flow (the A air-flow in Fig. 8) speed in Clean-suction nozzle region near the ground (a district in Fig. 8)Degree and flow, improve the ground refuse efficiency of kicking up, and can strengthen suction nozzle inner chamber front upper place region (Fig. 8 of Clean-suction nozzleIn b district) flow velocity and the flow of air-flow (the B air-flow in Fig. 8), the rubbish that is conducive to be kicked up is transported to suction inlet, fromAnd can improve efficiency and the conveying capacity of rubbish in suction nozzle inner chamber that rubbish is kicked up from ground, strengthen suction nozzle and inhale scavenge ability,Therefore improve the service behaviour of Clean-suction nozzle.
Wherein, the reason that b district air-flow is strengthened is on the one hand the air-flow (the C air-flow in Fig. 8) that entered by gas supplementing opening, and b district flows throughBe pooled to suction inlet, be that on the other hand the C air velocity that gas supplementing opening enters is higher, improve speed because siphonage drives B air-flowDegree.
