Compare prior art, the nozzle unit of the utility model increases switching mechanism, when running into the bigger rubbish thing of large stretch of leaf equal-volume; Elastic baffle is overturn; Increase the openings of sizes of suction nozzle, guarantee that the rubbish thing gets into the space of suction pipe, in the moment of elastic baffle upset; The suction nozzle negative pressure can not reduce, and can not influence suction effect.
For let the above-mentioned of the utility model and other purpose, feature and advantage can be more obviously understandable, hereinafter is special lifts preferred embodiment, and cooperates appended graphicly, elaborates as follows.
Description of drawings
Fig. 1 is a kind of part-structure sketch map of existing suction nozzle of sweeping car device.
Fig. 2 is the vertical view of nozzle unit in the utility model preferred embodiment.
Fig. 3 is the sectional view of Fig. 2 along the III-III line, shows the state diagram when elastic baffle is not dug.
Fig. 4 and Fig. 3 are similar, but have shown the state diagram when elastic baffle is dug.
The specific embodiment
Please be simultaneously with reference to Fig. 2 and Fig. 3, the nozzle unit 200 of the utility model preferred embodiment comprises framework 20, is located at the inlet scoop 30 on the framework 20 and is installed in the switching mechanism 40 in the framework 20.Form the cavity 22 towards ground in the framework 20, this cavity 22 communicates with inlet scoop 30.Framework 20 comprises the elastic baffle 24 that is positioned at cavity 22 1 sides and is positioned at the fixed head 26 at cavity 22 tops.The material of elastic baffle 24 is generally rubber, and the one of which end is fixed on the fixed head 26, other end ground proximity.
Switching mechanism 40 drives with elastic baffle 24 and is connected, and switching mechanism 40 comprises thrust unit 42, swivel plate 44 and pivot point 46.Thrust unit 42 comprises push rod 422.Swivel plate 44 is a bending plate, comprises substrate 442 and extension board 444, and wherein substrate 442 is connected with push rod 422, and extension board 444 supports with elastic baffle 24.Pivot point 46 is fixed on the framework 20, and swivel plate 44 can rotate around pivot point 46.Please be simultaneously with reference to Fig. 4, when push rod 422 stretched out, push rod 422 promoted swivel plates 44 and rotates around pivot point 46, extension board 444 promotes elastic baffles 24 distortion that curves inwardly, until with fixed head 26 applyings.Thereby the driver through control push rod 422 stretch out and regain control switching mechanism 40.
Preferably, pivot point 46 is for to be fixed on the bearing pin 46 on the framework 20, and substrate 442 is provided with the axle sleeve 446 (please with reference to Fig. 4) that cooperates with bearing pin 46 with extension board 444 junctions.
