The dimensional structure diagram looked up of mouth.
With reference to shown in Fig. 3 and 4, the cleaning car suction nozzle of the present embodiment includes the open housing 1 in lower section, and housing 1 surrounds suction
Room, the top of housing 1 are provided with pump orifice 2, and suction room is included positioned at first suction room 3 at the rear of pump orifice 2 and positioned at suction
Second suction room 4 in the front of mouth 2.Wherein front is the direction of advance of cleaning car.
Cleaning car suction nozzle also includes being used for the blower fan and the pipeline 8 of pump orifice 2 for connecting cleaning car.Further, car is cleaned to inhale
Mouth also includes wheel 7, in order to clean car suction nozzle smoothly with cleaning car movement.
First suction room 3 and the second suction room 4 communicate, can not be timely in the first suction room 4 during cleaning Chinese herbaceous peony is entered
Enter the rubbish of pump orifice 2, it is possible to enter 3 interior or the first suction room 3 lower section of the first suction room.
First suction room 3 communicates with pump orifice 2, and the rubbish of in the first suction room 3 or lower section of the first suction room 3 also can be
Entered in the presence of suction in pump orifice 2 and be sucked mouth 2 and siphoned away.Therefore, improve and car is cleaned present in prior art
The problem of rubbish in working range can not be drawn into dustbin by suction nozzle completely.
Further, the diversion component 5 that car suction nozzle also includes being located in the first suction room 3 is cleaned, diversion component 5 is used for will
The air intake of first suction room 3 guides to the front of diversion component 5, so that the air intake of the first suction room 3 and the second suction room 5
The joint of air intake moved towards the second suction room 4, above-mentioned joint is generally the starting point that rubbish moves upwards.
Diversion component 5 guides the air intake of the first suction room 3 towards the second suction room 4, while blows rubbish towards the second suction
Room 4 is moved, so as to extend time of the rubbish in the suction force range of pump orifice 2, add rubbish be sucked mouth 2 siphon away it is general
Rate.
The present embodiment, the width of the second suction room 4 is cumulative towards the direction away from pump orifice 2, so as to be advantageous to take out court
Suction inlet 2 converges.Further, the rubbish that pump orifice 2 fails to siphon away in time is also converged in the first suction room 3.
Fig. 5 shows 51 structural representation of the diversion component of the present embodiment.With reference to shown in Fig. 4 and Fig. 5, diversion component
5 include the first guide face 51 back to the second suction room 4, and the first guide face 51 is along direction from top to bottom towards the second suction room 4
Extension, the air intake of the first suction room 3 is guided towards the second suction room 4.
Diversion component 5 also includes the second guide face 52, and the second guide face 52 is taken out by the lower end of the first guide face 51 towards second
Suction-chamber 4 extends.
As shown in Figures 4 and 5, the bottom of diversion component 5 is provided with the projection towards the second suction room 4 protrusion.Second guide face 52
Including above-mentioned raised lower surface.
The lower end of diversion component 5 is higher than the lower surface of housing 1, in order to the first suction room 3 air intake towards pump orifice 2 or the
Two suction rooms 4 flow.Alternatively, the lower end of diversion component is higher than 5 to 30 millimeters of the lower end of housing 1.
Diversion component 5 includes concave face 53, and concave face 53 moves towards the second suction room 4 for buffering towards the first suction room 3
Dynamic rubbish, the rubbish buffered can also be sucked siphoning away for mouth 2.
As shown in figs. 4 and 6, the side wall of housing 1 is provided with the air channel 6 connected with the first suction room 3.
Air channel 6 extends along the extension that is directed downward from outside to inside, and along direction from outside to inside towards pump orifice 2, in order to
The rubbish of in the first suction room 3 and lower section of the first suction room 3 is blowed into the suction room 4 of pump orifice 2 or second, taken out with increasing rubbish
Time in the suction force range of suction inlet 2, so as to increase the probability that rubbish is sucked mouth 2 and siphoned away.
Alternatively, air channel 6 is 5 ° to 40 ° relative to the inclined angle of horizontal direction.Alternatively, air channel is relative to cleaning car
The inclined angle of direction of advance be 5 ° to 40 °.
Air channel 6 is that diversion component 5 is located near the air channel 6 of pump orifice 2 along the multiple of the direction of advance arrangement of cleaning car
Front, and positioned at pump orifice 2 rear.
Fig. 7 shows the schematic diagram of the cross section in the air channel 6 of the present embodiment, and cleaning car suction nozzle also includes being used to adjust air channel
The regulating member 9 of 6 circulation area.As shown in figure 3, further, cleaning car suction nozzle also includes controller 10, and controller 10 is used
In the speed controlling and adjusted part according to cleaning car, when cleaning the speed increase of car, reduce the circulation area in air channel, described
Increase the circulation area in air channel during the speed reduction for cleaning car.
Specifically, regulating member 9 includes the plate-shaped member that can be moved relative to air channel 6, to adjust the circulating face in air channel 6
Product.Cleaning car suction nozzle also includes being used for the screw rod for driving plate-shaped member to move.The screw thread being adapted with screw rod is provided with housing 1
Hole, screw rod are located in screwed hole and are connected with plate-shaped member, and screw rod drives plate-shaped member movement during rotating.
The motor that car suction nozzle also includes being used for drive screw turns is cleaned, the motor is connected with controller 10, so that control
The rotation of the controlled motor of device 10.
The upper end of first guide face 51 of diversion component 5 near the distance between air channel of pump orifice 2 be 20 to 80
Millimeter, it is therefore preferable to 40 to 60 millimeters.
First suction room 3 includes two side walls for being located at the both sides of pump orifice 2 respectively, and air channel 41 includes being respectively provided at two sides
The first air channel 61 and the second air channel 62 on wall.
The air-flow in the first air channel 61 and the second air channel 62 crosses, to blow afloat ground rubbish, and by rubbish to pump orifice 2 and
Two suction rooms 4 guide.
The position of first air channel 61 and the second air channel 62 in cleaning car direction of advance is concordant or misplaces.The He of first air channel 61
When second air channel 62 misplaces, the air-flow in the first air channel 61 and the second air channel 62 forms vortex, and the vortex can blow bigger weight
Rubbish, so as to improve the suction of the first suction room 3.
The cross section in air channel 6 is tapered along direction from outside to inside, to increase the speed of the air-flow of air channel 6.
Alternatively, the roof in air channel 6 and the height of bottom wall are by gradually reducing within outer, so that the air-flow phase in air channel 6
To horizontal direction, court tilts down.
The distance between the roof and bottom wall in air channel 6 by being gradually reduced within outer so that air channel 6 cross section along by outer
It is tapered to interior direction.
Alternatively, the section of the thickness direction of the parallel and housing 1 of the roof of air channel 6 is camber line or inclined relative to horizontal direction
Oblique straight line, so that the height of the roof in air channel 6 gradually reduces.
According to the another aspect of the application, the present embodiment additionally provides a kind of cleaning car, and the cleaning car includes above-mentioned clear
Clean car suction nozzle.
The exemplary embodiment of the present invention is the foregoing is only, is not intended to limit the invention, all spirit in the present invention
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
