Specific embodiment
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.It should be noted that in the feelings not conflicted
Under condition, the feature in embodiment and embodiment in the application can be mutually combined.
It should be noted that term used herein above is merely to describe specific embodiment, and be not intended to restricted root
According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative
Be also intended to include plural form, additionally, it should be understood that, when in this manual using belong to "comprising" and/or " bag
Include " when, it indicates existing characteristics, step, operation, device, component and/or combinations thereof.
In the present invention, upper and lower is to the upper and lower under referring to Clean- suction nozzle in working order to front and rear direction is
The direction consistent with the fore-and-aft direction of cleaning car, left side when left and right directions is in face of front when referring to Clean- suction nozzle in working order
Right direction.
As background technology is introduced, there is the poor technical problem of service behaviour of Clean- suction nozzle in prior art.
Explored to solve the technical problem, the reason for inventor is poor to the Clean- suction nozzle service behaviour of above prior art
And analysis.It was found that when the operating speed of cleaning car is accelerated, the suction of the Clean- suction nozzle of prior art to rubbish is picked up action time and is subtracted
Few, increasing rubbish does not suck suction inlet just from suction nozzle bottom " escape " in time, and the rubbish for causing suction nozzle rear portion to omit can be bright
It is aobvious to increase, car clean-up performance less stable is cleaned, as the capacity variation for changing its absorption rubbish of operating speed is larger, when
When operating speed increases, its ability for absorbing rubbish is drastically reduced；And the change of the Clean- suction nozzle terrain clearance of prior art
The suction of suction nozzle is directly affects, when under traveling to pavement roughness road conditions, suction nozzle suction is unstable, suction inlet lower section is intermittently
Leakage stack rubbish.
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 fluid force
Learn mechanism to understand, after air-flow enters through the road clearance in front of suction inlet, with obvious patch ground motion trend (effect near the ground
Phenomenon, is shown in a areas that A air-flows are formed in Fig. 3), cause to form relatively lower speed whirlpool in suction nozzle inner chamber, see B gas in Fig. 3
Stream.The effect in the air-flow a areas near the ground formed by A air-flows is kicked up in ground refuse to suction nozzle inner chamber, when ground refuse is thicker
Or the operating speed of cleaning car is very fast, causes part rubbish to be kicked up from ground.B positioned at inner chamber top is formed by B air-flows
Area, the air velocity in the b areas is relatively low, is unfavorable for making the rubbish kicked up be transported in suction inlet, causes rubbish to tire out in suction nozzle inner chamber
Product, reduces pumping efficiency.
For above technical problem, on the basis of exploring and analyze more than, a kind of Clean- suction nozzle is inventors herein proposed.
As shown in Fig. 4 to Figure 11, Clean- suction nozzle of the invention includes housing, suction inlet and gas supplementing opening.Housing has suction nozzle
Inner chamber.Suction inlet be arranged at the top of housing and with suction nozzle inner space.Gas supplementing opening is arranged at the top of housing and suction nozzle inner chamber connects
It is logical, also, gas supplementing opening than suction inlet closer to suction nozzle inner chamber front edge.
Fig. 8 is the suction inlet front air motion schematic diagram of the Clean- suction nozzle of first embodiment.This is illustrated below in conjunction with Fig. 8
The advantage of the Clean- suction nozzle of invention.
The Clean- suction nozzle is designed with gas supplementing opening on suction nozzle, and gas supplementing opening is arranged at the top of housing and suction nozzle inner chamber connects
It is logical, also, gas supplementing opening than suction inlet closer to suction nozzle inner chamber front edge.From hydrodynamics mechanism, in suction nozzle inner chamber negative pressure
In the presence of, air-flow can form one flow velocity air-flow higher from after the entrance of suction nozzle chamber outer wall.Under fluid viscosity effect,
The air motion around it can be driven compared with high gas flow, air speed nearby is improved.When air-flow from the upper front part of housing
After gas supplementing opening enters suction nozzle inner chamber, one high velocity air can be formed and flow to suction nozzle intracavity bottom, after one segment distance of patch ground motion, to
On be lifted into suction inlet, accordingly, with respect to the Clean- suction nozzle of prior art for, by gas supplementing opening enter suction nozzle inner chamber high speed
Air-flow (the C air-flows in Fig. 8) can improve air-flow (the A gas in Fig. 8 in Clean- suction nozzle region near the ground (a areas in Fig. 8)
Stream) speed and flow, improve ground refuse and kick up efficiency, and can strengthen the suction nozzle inner chamber front upper place region of Clean- suction nozzle
The flow velocity and flow of the air-flow (the B air-flows in Fig. 8) in (the b areas in Fig. 8), are conducive to the rubbish kicked up to be transported to suction inlet, from
And the conveying capacity of efficiency and rubbish that rubbish kicks up from ground in suction nozzle inner chamber can be improved, enhancing suction nozzle is inhaled and scavenges energy
Power, therefore improve the service behaviour of Clean- suction nozzle.
Wherein, on the one hand the reason for b areas air-flow is strengthened be that the air-flow (the C air-flows in Fig. 8) entered by gas supplementing opening flows through b
Area is pooled to suction inlet, further aspect is that the C air velocities that gas supplementing opening enters are higher, because siphonage drives B air-flows to improve
Speed.
