Compared with existing Clean-suction nozzle, the front apron of existing Clean-suction nozzle is quality of rubber materials, and the recovery coefficient of normal direction is less,Therefore rubbish is everlasting near the angle of front apron and upper sealing plate and is piled up, and is difficult for being absorbed. And the front of Clean-suction nozzle of the present inventionPlate 9 adopts resin skin to make, and has improved the recovery coefficient K of normal direction and tangential coefficientoffrictionμ, and the rubbish of motion is touched with itAfter hitting, be normal direction bounce-back trend, avoid horizontal the running helter-skelter of rubbish, draw chamber motion quilt in towards the first material of suction inlet 20 belowsSuck suction inlet 20. Can greatly reduce front end face and upper plate angle neighbouring sanitary fill and delay, improve infiltration rate.
As shown in Figure 5, in the present invention, Clean-suction nozzle also comprise respectively with multiple suction inlets 20 one by one corresponding arrange multiple secondMaterial draws chamber 50 in, and each the second material draws chamber 50 in and is arranged between the first material gathering chamber 10 and suction inlet 20, and the second material is receivedThe first end that holds together chamber 50 is communicated with suction inlet 20, and the second end that the second material draws chamber 50 in is communicated with the first material gathering chamber 10,Wherein, the recovery coefficient partly or completely of the internal face in the second material gathering chamber 50 is less than the recovery of the internal face of backboard 6Coefficient κ6。
Draw chamber 50 in by the second material is set, can make the rubbish that enters this second material gathering chamber be rapidly absorbed.
Wherein, the second material draws chamber 50 in and comprises spaced the second side plate 5, connects two of two the second side plates 5 respectivelyThe 3rd side plate 4 and two the 4th side plates 7 that are connected with the 3rd side plate 4, wherein, the part of the side wall surface of the 3rd side plate 4 or completeThe coefficientoffrictionμ of portion4Be greater than the part or all of coefficientoffrictionμ of the side wall surface of the second side plate 55, the side wall surface of the 4th side plate 7Part or all of coefficientoffrictionμ7Be greater than the part or all of coefficientoffrictionμ of the side wall surface of the 3rd side plate 44。
By above-mentioned setting, can improve solid refuse and the first material and draw the wall in chamber 10 and/or the second material gathering chamber 50 inCollision characteristic, reduce unnecessary mixed and disorderly rebound phenomena, accelerate it and absorbed by suction inlet 20, be conducive to promote Clean-suction nozzleAbsorption efficiency, reduces ground refuse and leaks.
The present invention also provides a kind of cleaning cart. Cleaning cart comprises chassis and is arranged on the Clean-suction nozzle of below, chassis, Clean-Suction nozzle is aforesaid Clean-suction nozzle.
The first embodiment
In the Clean-suction nozzle of prior art, the rubbish of motion and the first material draw in after the inwall collision in chamber 10, and bounce-back motion is acuteStrong, be presented on going hither and thither in cavity, be difficult to the effect of converging towards suction inlet 20 to rubbish that realizes, a part of solid refuse is subject toThe effect of air-flow continues to rebound in cavity, and collision is dropped ground from the leakage of Clean-suction nozzle rear, causes floor cleaning unclean.In order to address the above problem, technical scheme of the present invention is proposed.
As depicted in figs. 1 and 2, in the first embodiment of the present invention, suction inlet 20 is one, and recess 30 comprises two firstLinkage section 301 and be connected to two arc cornerite sections 302 between the first linkage section 301, suction inlet 20 is arranged on two first and connectsIn the angle region of close the arc cornerite section 302 that the section of connecing 301 forms, the internal face of the first linkage section 301 part or all ofRecovery coefficient be greater than the part or all of recovery coefficient of the internal face of arc cornerite section 302.
The rebounding characteristic that changes rubbish and inwall collision by said method, weakens the mixed and disorderly bounce-back campaign of rubbish gradually, improves fortuneMove track, thereby can greatly reduce the time of Clean-suction nozzle absorption rubbish.
Particularly, as shown in Figure 1, the second internal face 301b of one end of the close arc cornerite section 302 of the first linkage section 301Recovery coefficient be less than the recovery coefficient of the first internal face 301a of one end away from arc cornerite section 302 of the first linkage section 301.
Preferably, the internal face of stopper section 40 is made up of resin material, and the internal face of the first linkage section 301 is made up of glass, arcThe internal face of shape cornerite section 302 is made up of elastomeric material.
By above-mentioned setting, the first linkage section 301 is made up of glass, and the first linkage section 301 away from arc cornerite section 302The first internal face 301a of one end there is less recovery coefficient, after rubbish and the first linkage section 301 collisions, normal direction bounce-back subtractsA little less than, showing as this place's rubbish stronger along tangential bounce-back trend, motion is tending towards along the first linkage section 301 towards suction inlet 20 directions.Relative the first linkage section of recovery coefficient of the second internal face 301b of one end of the close arc cornerite section 302 of the first linkage section 301The recovery coefficient k of the first internal face 301a of one end away from arc cornerite section 302 of 301 reduces, and tangent direction friction coefficient μ increasesGreatly, after the second internal face 301b collision of solid refuse and the first linkage section 301, normal direction rebounds and tangentially rebounds compared with the first inwallFace 301a all weakens, and the unordered bounce-back campaign showing as after rubbish collision slows down greatly, and the rubbish that moves to this place can be inhaled as early as possibleMouth 20 absorbs.
In addition, as depicted in figs. 1 and 2, Clean-suction nozzle also comprises recess 30 and the stopper section 40 being connected with recess 30,Suction inlet 20 is arranged on one end away from stopper section 40 of recess 30, and recess 30 surrounds the first material with stopper section 40 and draws inChamber 10, the drawing on the side wall surface in chamber 10 and form Part I internal face, the court of recess 30 towards the first material of stopper section 40On the side wall surface in the first material gathering chamber 10, form Part II internal face, the coefficient of friction of the side wall surface of stopper section 40 and recessedEnter the coefficient of friction difference of the side wall surface of portion 30.
Wherein, the part or all of coefficient of friction of the side wall surface of stopper section 40 is greater than the part of the internal face of the first linkage section 301Or whole coefficient of friction. The part or all of coefficient of friction of the internal face of arc cornerite section 302 is greater than the sidewall of stopper section 40The part or all of coefficient of friction of face.
The coefficient of friction of the first internal face 301a of one end away from arc cornerite section 302 of the first linkage section 301 is greater than first and connectsThe coefficient of friction of the second internal face 301b of one end of the close arc cornerite section 302 of the section of connecing 301.
As shown in Figure 1, particularly, the rear with the Clean-suction nozzle of a suction inlet 20 is provided with as arc cornerite section 302Rear end face hinders rubbish, assembles the not only large but also speed of quantity of rubbish that moves to this place, and motion is violent. Due in rear endThe special wall material with less normal direction recovery coefficient k and larger tangent direction friction coefficient μ is set on face, as rubber composite,Making rubbish move to this place's bounce-back motion slows down and is inhaled in suction inlet 20. Thereby avoid the Clean-suction nozzle rubbish of prior artAfter this place and rear end face collision, because iron plate wall recovery coefficient is larger, cause energy loss less, the easy bullet of rubbish is from suction inlet20 and be difficult for absorbed problem.
